BRIEF SUMMARY OF THE INVENTION

The in Japanese Unexamined Patent Application Publication No. Hei 9-58920 however, the arrangement disclosed is such that the oscillation mechanism oscillates around the entire sheet size changing mechanism and the sheet registration plates and so on, whereby the inertial mass subjected to vibrational motion is large. Also, if the arcs are large in the width direction and may drop, for example, by a few millimeters, so that the amplitude for the movement of the sheet alignment plates back and forth, ie, the movement width, a margin of 10 mm, or the like, by this situation to encounter.

Consequently is the oscillation of the sheet registration plates at high speed difficult and there is a limit to increasing the speed of the Oscillation cycle.

Consequently without being able to increase the oscillation cycle, the Number of times to press down of the falling arc by means of the sheet registration plate elevated so that will improve the sheet alignment performance consists.

The The present invention provides a sheet registration device as well a sheet storage available, which is provided with it, and a sheet-fed printing press for increase the number of times an arc is depressed to the benefits to improve the sheet alignment of stacked sheets.

Likewise, the present invention provides a A sheet aligning device, and a sheet tray, a sheet fed printing press, and a sheet aligning method are provided to sufficiently handle the sheets which would otherwise fall down in the width direction in a highly unoriented manner and to improve the sheet aligning performance of the stacked sheets.

Furthermore The present invention provides a sheet registration device and a printing device arranged so arranged that they further improve the sheet registration performance of the sheets.

Around to solve the problems described above, the present invention Invention the following elements available.

This means that according to one First aspect of the present invention, a sheet alignment device is arranged so that they are on both sides of the direction to be issued is arranged in the direction of travel to the positions of this Bows in to align with the trap where the sheets are stacked and which ones comprising: a moving element provided to be in Width direction is movable to a frame; a sheet size changing mechanism, which is arranged so that it the movement element in the width direction emotional; a pushing element, which is attached so that it is widthwise on the bow side the movement element is movably mounted; and an approach / withdrawal mechanism, the is arranged so that it presses the element at a predetermined Timeline to the bows approaching and withdraw from these.

With the sheet straightening device according to the present aspect in the case that the width of the sheets is changed, the sheet size changing mechanism started, the moving elements are moved in the width direction of the sheets and the position of the pressing elements is moved to positions to make contact with both sides of the sheets. In this state, when the pressing elements are in the width direction the arches with the approach / retraction mechanism to be issued Bends approximates / from withdraw this from the pressing element so pressed that they are aligned in a position in the width direction.

Consequently the arch is pressed, while only the pressing element is vibrating, compared with the case currently the complete device oscillates, causing the section with the vibrating inertial mass can be significantly reduced.

By Reduction of sluggish Mass of the section to be vibrated can make the vibration cycle faster be made so that the number of times to press the issued bows in the width direction by the pressing element elevated can be.

Consequently For example, the sheet aligning performance in the width direction of the sheets can be improved become.

As well can the approach / retreat mechanism further comprising an elastic member so arranged is that it's the pusher presses elastically on the bow side; and a position regulating member arranged so that it is the movement of the pushing element on the sheet side by acting on the pressing member in the direction to retreat from the arches regulated and its regulatory position so causes them approach the sheets in a predetermined time / withdraw from the sheets.

According to the present Construction becomes the pressing element pressed continuously on the bow side by the elastic element, so that the pressing element by approaching / retreating the Regulating position with the position regulating element approaches the sheets / of the bows withdraws.

To this time pushes the position regulating element the pressing element in the direction around itself from the arches withdraw giving the force to press of the pressing element on the bow side only the elastic force of the elastic element is. Accordingly, for example, even if a situation acts occurs when an object sandwiched between the stacked Bow and the pressing element lies, so that the pressing element not the bow side moves, the elastic force from the elastic element only against the pressing element, so that too big Force not on the pusher acts. Therefore, breakage of the pressing member can be prevented.

According to the above it is described for construction the position regulating member desirably arranged to be that there is the regulatory position to the bows approximates / retracts a cam element, which is rotatably driven.

Consequently can the push element cyclic with respect to the bows only approximated / retracted by turning the cam member.

The operation of the sheet-fed printing press 1 according to the present embodiment as described above will now be described.

First, the printing operation of the sheet-fed printing press 1 to be discribed.

The ones on the discard pile board 11 the sheet store 3 stacked bows 9 are taken from the uppermost portion by means of a sheet feeding mechanism, not shown, sheet by sheet and the printing unit 5 fed.

The to the printing unit 5 fed bow 9 is with the gripper device of the intermediate cylinder 19 the printing unit 5 grabbed and while he was from the intermediate cylinder 19 is taken to the impression cylinder 17 guided. This is repeated to the bow through the printing unit 5 through to transport.

To every printing unit 5 Water is added to the non-image coverage areas on the surface of the printing cylinder 13 applied printing plate supplied from the moistening device, followed by supplied to the image cover portions of the printing plate from the ink supply device ink.

The printed image thus obtained on the printing plate is applied to the blanket cylinder 15 transfer.

That on the blanket cylinder 15 transferred print image is on a sheet 9 , the impression cylinder 19 is transported, then the printing of a color is carried out.

This will happen with each of the printing units 5 repeated to get a color print.

The sheet subjected to color printing 9 is guided down while he is back to the gripper device 19 of the chain gripper 21 from the impression cylinder 17 the last printing unit 5 is taken.

The with the gripper device 29 transported bow 9 is the removal of the staple at the top of the discard pile board 23 undergoes, falls down and becomes on the discard pile board 23 piled up.

At this time will prevent the ink from drying on the back of the sheet 9 is transferred to the upper side, the bow 9 beforehand blown with a powder when the bow from the gripper device 29 is transported.

Following is the batch operation of the sheets 9 on the discard pile board 31 described.

The positions of the vacuum suction wheel 43 , the rear sheet alignment device 39 and the width-aligning sheet-aligning device 35 (left bow registration section 47a and right bow registration section 47b ) are in accordance with the size of the output sheets 9 set.

For example, the positions are set with the solid lines in 2 are shown.

In this condition, the vacuum suction wheel becomes 43 rotated at a predetermined speed while a non-illustrated pump is operated to apply a set suction force.

Likewise, the electric motors 87 and 133 operated. Thus, the output waves rotate 95 and 141 over the retarder 89 and 135 so that the eccentric cams 91 and 137 rotate.

When the eccentric cam 91 and 137 rotated, the outer side end portions of the eccentric cams move 91 and 137 between the outer side position and the inner side position in one rotation. The movement is twice the eccentric (0.5 mm), so this is about 1 mm.

Thus, when the outer side end portions of the eccentric cams 91 and 137 be moved, the positions of the eccentric cam 91 and 137 indicating the movement of the cylindrically guided down element 81 and 127 regulate, cyclically moving towards the inside in the width direction.

When moving the cylindrical roller 81 and 127 the rear registration plate move 67 and the front alignment plate 113 integral in width direction B, as in 2 with the solid line and the narrow second-dot line (vibrated at vibration A (about 1 mm)) is shown.

At this time, the movement of the cylindrical roller 81 and 127 forced to the outside by the eccentric cams 91 and 137 against the force of the compression springs 85 and 131 The movement on the other side towards the inside is caused by the force of the compression springs 85 and 131 causes.

In this state, when the above-described pressure is executed, the sheet is made 9 with the gripper device 29 of the chain gripper 21 removed bracket with its rear end portion of an intake by the Vakuumsaugrad 43 subjected and thus controlled in a slow progress as it falls. The front end of the bow 9 bumps against the kick-off section 33 which stops its progress and aligns the position of the leading end portions.

At the same time, the positions on both sides can be aligned by being from both sides by means of the rear alignment plate 37 and the front alignment plate 113 be pressed.

The rear ends are stacked in a state where they pass through the rear sheet registration devices 39 be guided.

Thus, the rear alignment plate portion becomes 57 and the front alignment plate portion 103 only vibrates, the bows 9 so that, compared with a current situation where the entire device (including the size changing mechanism) is vibrated, the inertial mass of the portion to be vibrated is significantly reduced.

When the inertial mass of the portions to be vibrated is reduced, the vibration cycle can be made faster, so that the number of times for pressing the output sheets 9 by means of the rear alignment plate 67 and the front alignment plate 113 can be increased.

Thus, the sheet registration performance for the sheets 9 be improved in the width direction.

The eccentric cams 91 and 137 push the rear alignment plate section 57 and the front alignment plate portion 103 so that they are different from the bows 9 pull back, leaving the rear alignment plate section 57 and the front alignment plate portion 103 on the bow side 9 pressing force only the elastic force of the compression springs 85 and 131 is. Accordingly, for example, in such a case where there is something between the stacked sheets 9 and the rear registration plate 67 and the front alignment plate 133 is captured, leaving the rear alignment plate 67 and the front registration plate 133 not to the side of the bow 9 move, only the elastic force of the compression springs 85 and 131 on the rear alignment plate 67 and the front alignment plate 133 Applied so that excessive force does not affect the rear alignment plate 67 and the front alignment plate 133 or the like acts. Therefore, damage to the rear alignment plate 67 and the front alignment plate 133 and the like are inhibited.

Also, the rear end portion and the front end portion of the arches become 9 (ie both sides of the center of the arches 9 in the direction of movement of the sheets 9 ) by means of the rear alignment plate 67 and the front alignment plate 133 pressed, so that no torque is applied to rotate the arc surface. Therefore, the sheet aligning performance in the width direction of the sheets 9 be improved.

The following is a description of the handling in such a case where the size of the sheets to be printed 9 is changed.

As in 2 is shown in the case that the bow of a currently used bow 9 as shown by the solid lines, to a smaller arc 9 is changed, as indicated by the double-dotted lines, first the Vakuumsaugrad holding section 45 moved to the front and the position of the vacuum suction wheel 43 is moved to a predetermined position shown by the double-dotted line.

In accordance with the movement of the vacuum suction-wheel holding portion 45 towards the front, the rear sheet alignment device becomes 39 integral with the vacuum suction wheel holding section 45 is configured, moved to a predetermined position.

At the same time, the movement holding member moves 163 to the front side along the drive shaft 151 out. As a result of the movement of the movement-holding element 163 the rear rack move 143 and the rear sprocket 147 towards the front. In accordance with the movement of the rear rack, the rear width aligning section moves 49 towards the front and the rear alignment plate 67 is positioned in a position in engagement with the rear end portion of the new sheet 9 stands.

Thus, the rear width aligning section becomes 49 by means of the vacuum suction wheel holding section 45 , the vacuum suction wheel 43 keeps moving while maintaining a nearly constant positional relationship at the upstream end of the arc 9 is maintained and therefore automatically positioned in a nearly constant positional relationship with the trailing end of the sheet.

Accordingly, for adjusting the positions of the rear width-aligning unit 49 related to the sheet size change, the means for moving the rear alignment unit 49 and means for their adjustment are omitted.

Likewise, the front width alignment unit 51 provided with the position in the direction of travel of the fixed sheet and thus constantly positioned in a nearly constant positional relationship with the front end of the sheet.

Therefore, for adjusting the position of the rear width aligning portion 49 and the front width alignment section 51 in the direction of travel, the means for moving these sections and the means for adjusting these sections are omitted.

After that, when the electric motor 153 is driven and the drive shaft 151 over the retarder 155 is rotated, the rear sprocket 147 and the front pinion 149 turned. At this time stand the rear sprocket 147 that is not slidable on the drive shaft 151 is attached and fixed, in engagement with the corner portion of the drive shaft 151 ,

Thus, the drive shaft 151 with the hexagonal protruding portion integral with the drive shaft 151 rotated, so that a groove such as one with a key structure, does not have to be formed.

If the groove portion is not formed, a situation where the powder for preventing image transfer to the back side of the sheets is prevented 9 is inflated, but the powder accumulates in the grooves and prevents the back pinion 147 along the drive shaft 151 emotional.

If the rear sprocket 147 and the front pinion 149 are rotated, the meshing with the pinions racks 143 and 145 moved in the width direction B, so that the rear width alignment portion 49 and the front width alignment section 51 move in the width direction. Thus, the positions of the rear alignment plate 67 and the front alignment plate 113 be positioned in a predetermined position in the width direction B.

Thus, when the drive shaft 151 is rotated, the rear sprocket 147 and the front pinion 149 turned, the rear rack 143 and the front rack 145 that mesh with it are moved in the width direction B. Thus, the rear width aligning section 49 and the front width alignment section 51 be moved in the width direction, so that the position in the width direction B of the rear width alignment portion 49 and the front width alignment section 51 can be adjusted so that changes in width direction dimensions of the bows 9 can be countered.

It should be noted that in the present embodiment, the cross-sectional shape of the drive shaft 151 hexagonal, but not limited thereto, and any shape that can realize a combing structure to transmit a rotational driving force may be provided.

For example, a square shape as in 12 or a polygonal protruding shape having three or more angles can be used. Similarly, a reset polygon like the one in 13 shown used.

In addition, a round cross section, as in 14 shown to be provided with a corrugation extending key groove to the rear sprocket 147 engaged with a key 165 bring to. In this case, this is when the key 165 along the entire length of the key groove on the side of the drive shaft 151 is provided, this is effective for preventing the accumulation of powder in the key groove.

Also, with the present embodiment, the width direction position B of the sheet becomes 9 at two positions of the rear registration plate 67 and the front alignment plate 113 However, this alignment can also take place at three positions or more.

In addition, the sheet aligning performance in the width direction of the sheets 9 be improved with the slightest vibration of the alignment plate, so that they can be aligned in one position.

Following is another method of operation, which is the width direction sheet registration control unit 165 that in the 15 to 19 is shown is described.

The width direction sheet registration control unit 165 operates the electric motor 153 in a way that he drives the shaft 151 rotates, causing the rear sprocket 147 and the front pinion 149 to be turned around. At this time comes the rear sprocket 147 that is not slidable on the drive shaft 151 attached and fixed with this, in engagement with the angular portion of the drive shaft 151 ,

If the backward direction 147 and the front pinion 149 are turned, the meshing with the pinions rear racks 143 and front racks 145 moved in the width direction B, so that the rear width alignment section 49 and the front width alignment section 51 move in the width direction. Thus, the positions of the rear alignment plate 67 and the front alignment plate 113 in a predetermined position in the width direction B, with the size of the issued sheets 9 as they are with solid lines in 15 are shown, match, be positioned.

In this condition, the vacuum suction wheel becomes 43 rotated at a predetermined speed while operating a pump, not shown, to apply the set suction force.

Likewise, the width direction sheet registration control unit operates 165 the electric motors 87 and 133 and the electric motor 153 in a set operating mode.

With this mode of operation, the electric motors 87 and 133 as well as the electric motor 153 operated independently of each other.

The width direction sheet registration control unit 165 is driven so that they are the electric motors 87 and 133 continuously operates.

When the electric motors 87 and 133 rotate, the eccentric cams rotate 91 and 137 and the positions of the outer side end portions of the eccentric cams 91 and 137 move with each rotation between the outside position and the inside position. The movement is twice the eccentric (0.5 mm) and is therefore about 1 mm.

Thus, when the outer side end portions of the eccentric cams 91 and 137 to move, the positions of the eccentric cams 91 and 137 that control the movement of the cylindrical rollers 127 regulate towards the inside, cyclically moving in the width direction.

From the movement of the cylindrical rollers 81 and 127 vibrate the rear registration plate 67 and the front alignment plate 113 in clause gem dimensions integrated with each other in the width direction B, as in 15 is shown with the solid line and the narrow two-dot line, with a vibrating width D1 (normal forward and backward movement). The vibration width D1 is about 1 mm.

At this time, the movement of the cylindrical rollers 81 and 127 on the outside through the eccentric cam 91 and 137 against the force of the compression springs 85 and 131 Forcibly and the movement on the other side towards the inside is due to the force of the compression springs 85 and 131 causes.

On the other hand, with the width direction sheet registration control unit 165 at a certain interval, ie periodically or alternatively at a predetermined timing of the electric motor 153 for a defined time towards the rear registration plate 67 and the front alignment plate 113 that from the arches 9 are retracted, operated and the next step is operated in the opposite direction to the rear registration plate 67 and the front alignment plate 113 to return to the original position.

Thus, the rear alignment plate moves 67 and the front alignment plate 113 once in each case (large backward and forward movement) back and forth between the position of aligning the bow 9 periodically from a position retreated in the width direction from such a position. The vibration width D2 of this forward and backward movement is about 10 mm, for example.

The vibration width D2 is about 10 times the size compared with the vibration width D1 of the rear alignment plate 67 and the front alignment plate 113 that with the electric motors 87 and 133 be effected. It is desirable that the size of this vibration width D2 be several times larger than the vibration width D1.

Likewise, the specific interval is that of the electric motor 153 is not operated, for example, 5 seconds or 10 seconds.

This Interval or the vibration width D2 may be in terms of Type of sheets used, the printing speed, the sheet output state and the like are set appropriately become.

16 shows the trajectories Ka and Kb of the positions of the inner side end portions of the rear alignment plate 67a and 67b as well as the front alignment plates 113a and 113b in the case of synchronous operation of the electric motor 153a of the left bow registration section 47a and the electric motor 153b of the left bow registration section 47b ,

The electric motors 87 and 133 are operated independently, leaving the rear alignment plate 67 and the front alignment plate 113 minimal by the electric motor 153 even then vibrate when from the bows 9 withdrawn.

In this state, when the above-mentioned printing work is performed, the sheet becomes 9 from which the clamp of the gripper device 29 of the chain gripper 21 was removed and its end portion of the vacuum suction 43 sucked and thus controlled, slowly progressing while falling down. The front end of the bow 9 bumps against the kick plate 33 which stops its progression and aligns the leading end portions.

At the same time, the positions on both sides can be aligned by having both sides through the rear alignment plate 67 and the front alignment plate 113 be pressed.

The rear ends are stacked in a state in which they pass through the rear sheet alignment device 39 be guided and aligned.

At this time, a condition may exist in which a bow 9 clearly shifted in the width direction B is output. For example, as in 15 is shown in a case where the shift amount H from the predetermined position of the sheets 9 is greater than the vibration width D1, an alignment of the positions of the sheets with the minimum vibrations of the rear registration plate 67 and the front alignment plate 113 by means of electric motors 87 and 133 to be difficult.

According to the present embodiment, the rear alignment plate 67 and the front alignment plate 113 about the vibration width D2 with the electric motor 153 , which operates at a predetermined time sequence, moves forward and backward so that the shifted arc 9 back to the inside with the return movement of the movement can be pushed back and forth.

At this time, the rear alignment plate lead 67 and the front alignment plate 113 minimal vibrations through, giving them the bows 9 when bumping against the bow 9 can express what the width direction positioning the arches 9 further eased.

If the bow 9 enters the range of the vibration width D1, which is the minimum vibration, the positions of the arcs can 9 are accurately aligned with the minimum vibrations, so that even in the case where the sheet is dropped in a way that is largely shifted in the width direction, the sheet-aligning performance in the sheet width direction can be improved.

Thus, the bows 9 solely pressed by the rear alignment plate section 57 and the front alignment plate portion 103 are vibrated as compared with the case that the entire apparatus (including the sheet size changing mechanism) is oscillated, whereby the portion with the inertial mass to be vibrated can be significantly reduced.

By reducing the portion with the inertial mass to be vibrated, the vibration cycle can be made faster, so that the number of times for pressing the output sheets 9 by means of the rear alignment plate 67 and the front alignment plate 113 can be increased in the width direction.

Thus, the sheet aligning performance in the width direction of the sheets 9 be improved.

It should be noted that in the present embodiment, the electric motor 153a of the left bow registration section 47a and the electric motor 153b of the right arch registration section 47b be operated synchronously, but differently than synchronously operated and in 17 shown, the operation of the motors can also be done with a different timing.

Thus, on the one hand, for example, vibrate when the rear alignment plate 67a and the front alignment plate 113a then hit the bow, if this strong as in 15 shown shifted to the left side, the rear alignment plate 67b and the front alignment plate 113b Minimal and stand near the predetermined positions so that they can prevent the bow 9 is shifted strongly to the right side.

Also, in the present embodiment, the electric motors 87 and 133 as well as the electric motor 153 arranged so that they can be operated independently, but can also be operated synchronously.

In this case, for example, as in 18 shown, the peaks of the vibration width D2 by the electric motor 153 and the tip of the minimum vibration by the electric motors 87 and 133 be so adapted to each other.

Thus, for example, the distance to retract the rear alignment plate 67 and the front alignment plate 113 large, so that the amount of movement of the rear holding section 55 and the front holding portion 101 due to the electric motor 153 can be set correspondingly smaller.

Likewise, for example, as in 19 shown the electric motors 87 and 133 stop synchronously when the electric motor 153 is operated.

Thus, the electric motors 87 and 133 be stopped at a time when the position alignment of the sheets 9 less is required, so that energy consumption can be reduced.

The left sheet alignment unit 201 and the right sheet registration unit 201b are arranged symmetrically to each other and surround the arches 9 from both sides and have a generally symmetrical structure to each other.

It should be noted that in the description given below, the left Bogenausrichtungseinheit 201 and the right sheet registration unit 201b are constructed symmetrically, so that the left sheet alignment unit 201b will be described in detail and the description of the right sheet alignment unit 201b is omitted, unless a description of this is necessary. Similarly, the left sheet registration unit 201 and the right sheet registration unit 201b be distinguished by the addition of the suffix "a" or "b" after the reference character. This means that "a" is a section or element on the left sheet registration unit 201 describes and that "b" is a section or element on the right sheet registration unit 201b features. Subsequently, in the description or in the diagrams, a or b are given in such cases as the left sheet registration unit 201 and the right sheet registration unit 201b but if they are not particularly distinguishable, the section or element is indicated by its reference numeral, and the suffix a or b is omitted.

The left sheet alignment unit 201 has a rear alignment unit 220 and a front alignment unit 240 which serve as width alignment units. The rear alignment unit 220 and the front alignment unit 240 are successively along the travel direction L of the sheets 9 provided, ie that the rear alignment unit 200. on the upstream side (back), whereas the front alignment unit 240 is provided on the downstream side (front side). The rear alignment unit 220 serves to align the position of the rear end portion of the sheet 9 in the width direction B, while the front alignment unit 240 for aligning the positions of the front end portion in the width direction B is used. In addition, the left sheet registration unit points 201 a size change mechanism 280 as the sheet size changing mechanism for changing the positions of the rear aligning unit 220 and the front alignment unit 240 following the width direction B, which corresponds to the widthwise width B of the sheets 9 corresponds, as in 22 is shown.

Now the rear alignment section is 220a the left sheet registration unit 201 and the rear alignment section 220b the right sheet registration unit 201b and the front alignment section 240a the left sheet registration unit 201 and the front alignment section 240b the right sheet registration unit 201b each equivalent to a pair of width-alignment units according to the present invention. This means that the width direction sheet alignment device 200. According to the present embodiment, two pairs of width-alignment units according to the present invention in the direction of travel L has. The rear alignment section 220a and the rear alignment section 220b are at the rear end portion of the arches 9 provided so that they are aligned in the width direction B on both Verfahrrichtungsseiten the sheets 9 whereas the front alignment section 240a and the front alignment section 240b at the front section of the arches 9 are provided so that they face each other in the width direction B at both Verfahrrichtungsseiten the sheets 9 face.

It should be noted that in the description given below the 23 to 28 the rear alignment unit 220 and the front alignment unit 240 generally symmet are built so that the structure of the front alignment unit 240 will be described in detail and the description of the rear alignment unit 220 as long as its specific description is not required. At the rear alignment unit 220 however, is the length of a rear registration plate 221 serving as a sheet alignment member and a holding plate 223 serving as a holding member, which will be described later, slightly shorter than the front alignment plate to the travel direction L 241 and the holding plate 243 the front alignment unit 240 ,

The front alignment unit 204 has a front alignment plate 241 serving as a sheet alignment member, an oscillation unit 242 which serves as an oscillation unit, and a holding plate 243 , which serves as a holding element, as shown in the 23 and 28 is shown. The front alignment plate 241 is formed in a plate shape, wherein the side along the travel direction L is the long side. The holding plate 243 is formed in a nearly L-shaped plate shape and while the oscillation unit 242 is fixed and fixed to the surface of the upper side in the vertical direction, is a front rack described later 282 fixed to the surface of the lower side in the vertical direction. The oscillation unit 242 has a plate spring 244 (Spring element), which serves as a pressing element, and an eccentric cam mechanism 245 serving as the oscillation drive mechanism.

The plate spring 244 points, like this in 24 is shown a base end portion 246 on, on the retaining plate 243 is fixed, a folded-back section 247 at the lower side in the vertical direction (in the stacking direction of the sheets 9 ) of this base end section 246 is provided, as well as a tip section 248 which is on the upper side in the vertical direction over the folded-back section 247 folded back. The base end section 246 is on the plate spring mounting portion 249 fixed by the lower surface of the retaining plate 243 protrudes. At the plate spring 244 the tip section extends 248 who is on the bow 9 with the folded-back section 247 folded back, upwards in the vertical direction. That means the plate spring 244 is formed with a cross section in which the short side direction has a nearly J-shape.

The front alignment plate 241 is at the surface of the top section 248 the plate spring 244 at the bow side 9 fixed so that she is able to be in contact with the bow 9 in the width direction side section while passing through the holding plate 343 with the plate spring 244 is supported. The plate spring 244 is elastic with the folded-back section 247 rotatable in the lower portion in the vertical direction as a fulcrum and the front alignment plate 241 may be in the width direction B with the tip portion of the folded-back portion 247 the plate spring 244 oscillate as Oszillationsdrehpunkt.

Accordingly, the front alignment plate 241 an oscillation fulcrum on the underside in the vertical direction and the plate spring 244 is supported so as to be able to oscillate in the width direction B with the oscillation fulcrum as the center, and also to the side of the arc 9 pressed down. The plate spring 244 pushes the front alignment plate 241 in the direction of the bow 9 and puts a force on the front alignment plate 241 on to the bows 9 to press. As already described above, the front alignment plate is 241 formed in a rectangular plate shape, wherein the side along the travel direction L is the long side, and so forms the oscillation fulcrum at the tip portion of the folded-back portion 247 a horizontal axis of oscillation along the travel direction L from.

As already described above, by providing a front registration plate 241 at the top section 248 , with the folded-back section 247 folded back, wherein the base end portion 246 on the retaining plate 243 is fixed, provided a structure in which an oscillation fulcrum at the lower portion of the front alignment plate 241 is ready and the upper end portion of the front registration plate 241 is supported so that it is able to oscillate, and a structure in which the front alignment plate 241 on the side of the arches 9 is pressed, can be realized simultaneously.

As in 25 shown is a cut-out section 254 on the front registration plate 241 formed on the vertically downwardly directed portion. The front alignment unit 240 has a regulation plate 255 inside this cut-out section 254 on. The regulation plate 255 is formed in a plate shape and on the holding plate 243 at the side of the oscillation fulcrum on the front alignment plate 241 fixed. The regulation plate 255 is a plate-shaped element that acts as a separate unit from the front alignment plate 241 is formed, with the surface on the side to the sheets 9 almost with the surface of the arches 9 down in the vertical direction of the front alignment plate 241 is aligned and in contact with the width direction side portion of the sheets 9 can get. As already described above, the front alignment plate becomes 241 through the retaining plate 243 by means of the plate spring 244 supported so that they are relative to Retaining plate 243 can be moved while the regulation plate 255 on the retaining plate 243 is fixed and so not in relation to the retaining plate 243 can be moved.

The eccentric cam mechanism 245 has an electric vibration motor 250 on, which serves as an engine, an eccentric cam 251 , a connection 252 and a cam-side boom 253 like this in the 23 and 26 is shown. The cam-side boom 253 is on the surface of the retaining plate 243 fixed at the top in vertical direction. The electric vibration motor 250 can be rotatably driven and has an output shaft 256 at an end portion. The electric vibration motor 250 is on the cam-side boom 253 so attached, that the output shaft 256 in the cam-side boom 253 is used.

The eccentric cam 251 is at the output shaft 256 the electric vibration motor 250 intended. The eccentric cam 251 is about two roller bearings 257 within the cam-side boom 253 supported. The eccentric cam 251 is formed in such a shape that the number of cylinders are stacked, and an axial line is positioned in the center thereof so that the position exceeds a predetermined amount d (for example, 0.5 mm) horizontally from the rotation axis of the electric vibration motor 250 is moved.

One end portion side of the connection 252 is with the eccentric cam 251 and the other end portion side is with the front alignment plate 241 Mistake. One end portion side of the connection 252 runs through the side wall of the cam-side arm 253 and an insertion opening 258 is inside the cam-side cantilever 253 educated. The connection 252 has a roller bearing 259 in this insertion hole 258 on, with the eccentric portion of the eccentric cam 251 over the roller bearing 259 is used. The connection 252 and the eccentric cam 251 are relatively rotatable with the roller bearing 259 connected.

Likewise, the connection shows 252 a connection section 260 on top of the front registration plate 241 and the eccentric cam mechanism 245 connects to the other end section side. The connecting section 260 has a slot 261 which serves as a cut-out section, a pen 262 which serves as a protruding portion, and a sheet alignment plate side. boom 263 like this in the 26 and 27 is shown. The sheet registration plate side boom 263 is at the back (the back surface of the surface of the sheet side 9 ) of the top section 248 the plate spring 244 fixed. The slot 261 is on the other end section side of the link 252 formed, ie in the end portion on the side opposite the end portion, with which the eccentric cam 251 connected is. The slot 261 is in the width direction B, that is, along the pressing direction of the plate spring 244 intended. The pencil 262 is fixed to the sheet registration plate side boom 263 attached while in the slot 261 is used. The slot 261 and the pen 262 point between them along the pressing direction of the plate spring 244 a pre-determined space. Accordingly, the front alignment plate 241 with the connection 252 the eccentric cam mechanism 245 at the connection unit 260 over the plate spring 244 and the sheet registration plate side delivery 263 connected while a widthwise width B according to the distance along the printing direction between the slot 261 and the pen 262 is present. As a result, for example, in a case where one of the chain gripper 21 falling bow 9 in a significantly offset position or if a foreign object falls between those on the discard pile board 23 stacked bows 9 and the front alignment plate 241 is captured and what a big burden on the front alignment plate 241 or the plate spring 244 causes the front alignment plate 241 or the top section 248 the plate spring 244 in a retraction direction of the sheet in accordance with the distance along the pressing direction between the slot 261 and the pen 262 emerge, thereby preventing an unnecessary force greater than the urging force of the plate spring 244 is on the front registration plate 241 or the plate spring 244 is applied.

In the eccentric cam mechanism constructed as described above 245 is the output wave 256 the electric vibration motor 250 rotatably driven, causing the eccentric cam 251 also with the output wave 256 turns and the connection 252 Moves back and forth along the width direction B over a distance according to the Exzentermaß (predetermined amount d). Then the eccentric cam mechanism can become 245 with the along the width direction B back and forth moving connection 252 the upper portion of the front alignment plate 241 between the sheet registration position, in contact with the sheets 9 comes (with the middle solid lines in 24 shown) and the waiting position, by the arches 9 is withdrawn (shown with middle dotted lines in 24 ) move back and forth. In particular, the eccentric cam mechanism pulls 245 with the rotating eccentric cam 251 and in the retreat page the bows 9 along the width direction B moving connection 252 as with the dotted lines in 24 shown is the front alignment plate 241 and the top section 248 the plate spring 244 in a direction to pull back from the arches 9 so that the top section 248 the plate spring 244 on the back (the side opposite the arches 9 ) with the tip portion of the folded-back portion 247 as the center positioned oscillation fulcrum points. Thus, the upper portion of the front alignment plate rotates 241 in the vertical direction with the tip section 248 the plate spring 244 so as to get away from the bows 9 to withdraw with an oscillation fulcrum as the center. The eccentric cam 251 then turns on and the connection 252 moves so that it is the bow side 9 along the width direction B, whereby the tip portion 248 the plate spring 244 to the bows 9 returns with an oscillation fulcrum as the center. Thus, the upper portion of the front alignment plate rotates 241 in a vertical direction on the arches 9 along with the top section 248 the plate spring 244 with an oscillation fulcrum as the center. Accordingly, a vibration section 242a the upper portion of the front alignment plate 241 in the width direction B of the sheets 9 oscillate.

The front alignment plate 241 oscillates with the tip portion of the folded-back portion 247 as the oscillation fulcrum, so that as the oscillation distance at the upper portion becomes longer in the vertical direction, the oscillation distance at the lower portion becomes shorter and becomes almost zero at the lowermost portion near the oscillation fulcrum. It should be noted that the position at which the front alignment plate 241 the bows 9 is closest, ie the position of the front alignment plate 241 in the case of that connection 252 in a position closest to the arches 9 stands, according to the width directional length of the sheets 9 by means of a sheet change mechanism 280 is set, which will be described next, that is, in a position at which the side portions of the sheets 9 not be pressed down.

The drive shaft 285 is in its intermediate section (an area of the front main unit 288 and the rear attachment member 289 ) formed with a cross-sectional shape in almost hexagonal shape. The retarder 287 is on the front main unit 288 over a mounting plate 290 attached to the front surface side (downstream side in the travel direction L) of the front main unit 288 is fixed. Likewise, the retarder 287 provided such that the output shaft 291 along the travel direction L, while with the drive shaft 285 connected is. The electric engine 286 is on the front surface side of the retarder 287 appropriate.

The front pinion 284 is mounted so that it is not in the axial direction of the drive shaft 285 emotional. The front rack 282 is arranged so that it with the front pinion 284 meshes and extends along the width direction B and slidably through the front main unit 288 is held. The front rack 282 is constructed so that the arc-side end portion on the lower surface of the holding plate 243 on the front alignment unit 240 (please refer 24 ) and along the width direction B in an integrated manner with the front alignment unit 240 is mobile.

The rear sprocket 283 is movable in the axial direction of the drive shaft 285 appropriate. Likewise, the rear sprocket 283 rotatable by the movement-holding element 292 supported. The rear rack 281 is like this in the 29 and 30 is shown, arranged so that it with the rear sprocket 283 meshes and extends along the width direction b and slidable by the movement-holding member 292 is held. The rear rack 281 is similar to the front rack 282 constructed so that the arc-side end portion on the lower surface of the holding plate 223 at the rearward alignment unit 220 is fixed and along the width direction B in an integrated manner with the rear alignment unit 220 is mobile. The movement holding element 292 is on the vacuum wheel support unit 45 fixed. The vacuum wheel support unit 45 is movable along the travel direction L by means of a frame (not shown) of the tray 7 supported. Accordingly, the movement holding member 292 movable in travel direction L with the vacuum wheel support unit 45 in accordance with the movement of the vacuum wheel support unit 45 built in the direction of travel L.

The width direction sheet alignment device 200. further comprises a control device 300 acting as a control unit for controlling the drive of the size change mecha mechanism 280 serves as well as a sample removal switch 304 serving as a detection unit, as shown in FIG 31 is shown.

In addition, in the control device 300 the input / output device 303 of the sampling switch 304 electrically connected to each other. The input / output device 303 is for the input of instructions by the worker in the case of the operation of the sheet-fed printing press 1 or to indicate the operating state of the sheet-fed printing press 1 arranged for a worker and has an operation panel, a monitor and so on. From the input / output device 303 are pre-set instructions for previously adjusting the size of the sheets 9 by means of the operation of a worker, input, whereby the processor unit 301 the control device 300 the drive of the vacuum suction device 37 or the size change mechanism 280 according to the pre-set instructions, to the rear alignment unit 220a , the rear alignment unit 220b , the front alignment unit 240a and the front alignment unit 240b to a predetermined position according to the size of the sheets 9 to move. When the sample removal switch 304 was turned on by the operation of a worker, a sample removal signal to the control device 300 be transmitted. It should be noted that in the present embodiment, the input / output device 303 as well as the sample removal switch 304 are constructed as separate devices, the input / output device 303 however, it can also be used as a detection unit according to the present invention.

Upon receipt of the sample removal signal from the sample removal switch 304 in the case of turning on the sample removal switch 304 by the operation of a worker and the generation of a sample removal signal, the control device drives 300 the electric impulse motor 304 for rotation of the shaft 41 on and the kick-off unit 33 will, as in the dotted lines in 20 is shown pushed down the direction of travel L downstream, whereby the abutment unit 33 held in an open position. Thereafter, the control device controls 300 the drive of the electric motors 286a and 286b the size change mechanism 280a and 280b to the holding plates 223a . 223b . 243a and 243b (please refer 22 ) from the bows 9 withdraw in the width direction B, whereby the rearward alignment unit 220a , the rearward alignment unit 220b , the front alignment unit 240a and the front alignment unit 240b each over a predetermined distance (for example, about 5 mm) from the sheets 9 be withdrawn. After the sample removal switch 304 was turned off by the operation of a worker drives the control device 300 the electric impulse motor 304 for rotation of the shaft 41 on, the kick-off unit 33 is raised in the travel direction L to the downstream side, whereby the abutment unit 33 is held in closed position, then it controls the drive of the electric motor 286a and 286b for approaching the retaining plates 223a . 223b . 243a and 243b (please refer 22 ) near the arches 9 along the width direction B and guides the rear alignment unit 220a , the rear alignment unit 220b , the front alignment unit 240a and the front alignment unit 240b back to their original position.

In addition, the control device controls 300 the drive of the electric oscillation motors 130a . 130b . 250a and 250b to the setting timing of the rear registration plates 221a and 221b and the front alignment plates 241a and 241b the respective rear alignment unit 220a , the rear alignment unit 220b , the front alignment unit 240a and the front alignment unit 240b to contact with the bows 9 make and be mutually asynchronous.

Subsequently, the operation of the above-described sheet-fed printing press 1 and the width direction sheet alignment device 200. to be discribed. First controls, after the size of the bows 9 from a worker via the input / output device 303 is entered, the control device based on the inputted size information about the sheets 9 the vacuum suction device 37 and the electric motors 286a and 286b the size change mechanism 280 so the vacuum suction wheel 43 , the rear sheet alignment device 39 , the rear alignment unit 220a , the rear alignment unit 220b , the front alignment unit 240a , and the front alignment unit 240b to predefined positions (for example, the lines drawn in 21 shown positions) according to the open of the arches 9 to move.

After receiving the print start signal from the input / output device 303 the control device starts 303 the drive of the various drive units of the sheet feeder 3 including the electric oscillation motors 230a . 230b . 250a and 250b , the pressure unit 2 and the filing 7 ,

The ones on the discard pile board 11 the sheet feed 3 piled sheets 9 are transferred from the uppermost section sheet by sheet through the sheet conveying mechanism 6 removed and to the printing unit 5 the printing unit 2 promoted. The bows 9 leading to the printing unit 5 are transported by each printing unit 5 by successively passing down through the gripper devices (not shown) of the impression cylinder 17 and the intermediate cylinder 19 every printing unit 5 passed through, during which transport ink is added.

With every printing unit 5 Water is added to the non-image coverage areas of the printing plate, which are on the surface of the printing cylinder 13 is attached by a moistening device (not shown), followed by ink, which is conveyed to the image covering portions of the rotating platform by means of an ink conveying device (not shown). The printed image thus obtained on the printing plate is applied to the blanket cylinder 15 transferred. That to the blanket cylinder 15 transferred print image is on the sheet 9 transferred from the impression cylinder 17 is transported, and the printing of a color is carried out. This will happen with every printing unit 5 repeatedly to carry out color printing.

The sheet subjected to color printing 9 is through the gripper 15a of the chain gripper 21 from the impression cylinder 17 the last printing unit 5 passes down, seized. the arc 9 , the gripper 15a is transported, the removal of a staple at the top of the discard pile board 23 is dropped and dropped on the discard pile board 23 stacked. At this time, it will prevent the non-dried ink on the back of the sheet 9 transferred to the top, in advance a powder on the sheet 9 inflated when the bow with the gripper 15a is transported.

During this time is by the vacuum suction 43 that rotates at a predetermined speed, and a suction unit (not shown) such as an operated pump, a predetermined suction force on the tray 7 applied. The electric oscillation motors 130a . 130b . 250a . 250b rotatably drive, whereby the upper end portions in the vertical direction of the rear alignment plates 221a and 221b as well as the front alignment plates 241a and 241b the respective rear alignment units 220a . 220b and the front alignment units 240a . 240b along the width direction B with the oscillation fulcrum of the lower end portion in the vertical direction as the center.

In this state, as already described above, the bow 9 from which the clamp by means of the gripper 15a of the chain gripper 21 was removed, at the rear end portion by the Vakuumsaugrad 43 sucked and controlled, slowly led forward and dropped. The front end of this bow 9 pushes against the impulse unit 33 and its progress is stopped and the leading end portion positions are aligned. At the same time, the rear end portion side of the arch 9 through the rear alignment plate 221a and the rear alignment plate 221b pressed and the front end portion side is through the front alignment plate 241a and the front alignment plate 241b from both sides in the width direction B, whereby the positions in the width direction B can be aligned. The back end of the bow 9 is then passed through the back sheet registration device 39 guided and aligned and the bow 9 gets on the donation stack board 23 is stacked in a state of alignment in the travel direction L and width direction B, as shown in FIG 24 is shown.

At this time, for example, with the front registration plate 241a only the upper portion oscillates in the vertical direction, with the tip portion of the folded-back portion 247a at the bottom in the vertical direction serves as oscillation fulcrum, whereby the oscillation unit 242a the section to be oscillated with the front alignment plate 241 whose inertial mass is reduced and the oscillation cycle of the front alignment plate 241a can be made faster. Accordingly, the number of times for pressing the falling sheets 9 be increased in the width direction, whereby the sheet alignment performance is improved for the sheets. In addition, since the front alignment plate 241 with the tip portion of the folded-back portion 247a oscillates as oscillation fulcrum, the oscillation distance longer than the upper end portion side in the vertical direction to be in contact with the arc 9 while falling, whereas the contact at the lower end portion side to contact with those on the storage board 23 stacked bows 9 becomes shorter so that the widthwise positions of the sheets 9 during the fall can be safely aligned while also preventing unnecessary vibrations on the sheets 9 on the storage board 23 stacked, are applied, which ultimately also confirms the bows 9 is prevented.

Likewise, for example, a regulatory plate 255a at the lower portion of the front alignment plate 241a provided in the vertical direction, with the front alignment plate 241a relative to retaining plate 243a can be moved while the regulation plate 255a not relative to retaining plate 243a is moved, reducing the positions of the storage board 23 stacked bows 9 safely in the width direction B can be maintained.

Likewise, the rear alignment plates 221a and 221b as well as the front alignment plates 241a and 241b formed in a rectangular shape with the long side along the travel direction L, as described above, so that the surface area in contact with the widthwise side portions of the sheet 9 passes, with the rear registration plate 221a and 221b as well as the front alignment plates 241a and 241b is made wide, what the orientation of the bows 9 in the width direction, and also there the oscillation fulcrum of the tip portion of the folded-back portion 247 forms a horizontal axial oxidation line along the travel direction L, wherein the Oszillationsmaß the rear alignment plates 221a and 221b as well as the front alignment plates 241a and 241b is constant in the horizontal direction and the contact state with the arches 9 can be kept constant in the horizontal direction.

In addition, the control device controls 300 the drive of the electric oscillation motors 130a . 130b . 250a and 250b for adjusting the timing, leaving the upper sections of the rear registration plates 221a and 221b as well as the front alignment plates 241a and 241b the respective rear alignment unit 220a , rear alignment unit 220b , front alignment unit 240a and front alignment unit 240b come in contact with the arcs mutually asynchronously, whereby the oscillation cycles of the four rear alignment plates 221a and 221b as well as the front alignment plates 241a and 241b are not aligned, so even if the fall positions of the bows 9 that of the chain gripper 21 fall down, are scattered, the bows 9 can be collected reliably in the predetermined position.

Likewise, in the width direction sheet alignment device 200. two pairs of width alignment units of the rear alignment unit 220a and the rear alignment unit 220b and the front alignment unit 240a and the front alignment unit 240b provided along the travel direction L, so that while the rear alignment unit 220a and the rear alignment unit 220b the widthwise position of the sheets 9 at the rear end portion of the arches 9 align, the front alignment unit 240a and the front alignment unit 240b the widthwise positions of the sheets 9 at the front end portion of the sheets 9 Align so that a torque for rotating the arc surface is not applied.

Upon receiving a print stop signal from the input / output device 303 stops the control device 300 the drive of the various drive units of the sheet feeder 3 , the pressure unit 2 as well as the filing 7 including the electric oscillation motors 130a . 130b . 250a and 250b ,

In case of removal of a sample of a bow 9 that was subjected to a pressure from those on the storage board 23 stacked bows 9 during operation of the sheet-fed printing press 1 as a result of receipt, a sample removal signal at the sample removal switch 4 , drives the control device 300 the electric impulse motor 305 to hold the push unit 33 in an open position. Thereafter, the control device controls 300 the drive of the electric motors 286a and 286b the size change mechanism 280a and 280b for temporarily retracting the rear alignment unit 220a . the rear alignment unit 220b , the front alignment unit 240a and the front alignment unit 240b of bows 9 over a predetermined distance, creating a space through the impulse unit 33 formed downstream in the travel direction L, through which a sample of the stacked sheets 9 is removed, during which process prevents the bow 9 on the rear registration plate 221a and 222b as well as the front alignment plate 241a and 241b is taken.

Subsequently, the operation is described in a case where the size of the bow 9 is changed for printing. As in 21 is shown in the case that a change of an arc 9 with the solid line, which is the current print job, to a smaller arc 9 is changed with the two-dot broken line, first a vacuum wheel support unit 45 moves forward and the position of the vacuum suction wheel 43 is moved to a predetermined position indicated by the two-dot chain line. In accordance with the movement of a vacuum wheel support unit 45 toward the front side, the back sheet aligning device becomes 39 integral with the vacuum wheel support unit 45 is configured to move to a predetermined position. At the same time, the movement holding elements move 292a and 292b along the drive shafts 285a and 285b Forward. Along with the movements of the movement-holding elements 292a and 292b become the rear racks 281a and 281b as well as the rear sprockets 283a and 283b moved forward. Along with the movements of the rear racks 281a and 281b become the rear alignment units 220a and 220b moved forward and the rear alignment plates 221a and 221b are arranged in a position capable of being in contact with the rear end portion of the new sheet 9 to get.

Thus, the rear alignment units become 220a and 220b through the vacuum wheel support unit 45 that the vacuum suction wheel 43 holds and which the positional relationship with the upstream edge of the bow 9 keeps almost constant, moving, causing the constant positional relationship with the rear end of the arc 9 automatically positioned and kept almost constant. Accordingly, for the position adjustment of the rear alignment unit 220a and 220b that the size change of the bow 9 follow, the means for moving and the means for adjusting are omitted. Likewise, the positions of the front alignment unit 240a and the front alignment unit 240b fixed in the direction of travel L of the bow 9 provided so that they are constant in a nearly constant positional relationship with the leading edge of the bow 9 are positioned. Therefore, to adjust the positions of the rear alignment units 220a and 220b and the front alignment units 240a and 240b in the direction of travel, the means for moving and the means for adjusting are omitted.

Following are the electric motors 286a and 286b are operated and the drive shafts 285a and 285b over the retarder 287a and 287b turn the rear sprockets 283a and 283b and the front sprockets 284a and 284b to be turned around. At this time stand the rear sprockets 283a and 283b Slidable on the drive shafts 285a and 285b are attached, but not fixed to this, with the corner portions of the drive shafts 285a and 285a engaged, the cross-sectional shape is almost hexagonal, and are rotated.

After the rear sprocket 283a and 283b and the front sprockets 283a and 284b turn, the meshing with these rear racks 281a and 281b and front racks 282a and 282b moved in the width direction B, leaving the rear alignment units 220a and 220b and the front alignment units 240a and the front alignment unit 240b to move in the width direction B Thus, the rear alignment plates 221a and 221b as well as the front alignment plates 241a and 241b be positioned in a predetermined position in the width direction B.

Thus, the width direction sheet aligning device has 200. according to the present embodiment, rear alignment units 220a and 220b and front alignment units 240a and 240b on, on both sides in the direction L of the sheets 9 which are subjected to printing, and the positions in the width direction B of the sheets 9 in the case of stacking the bows 9 align, and the rear alignment unit 220a , the rear alignment unit 220b , the front alignment unit 240a and the front alignment unit 240b have rear alignment plates 221a and 221b and front registration plates 241a and 241b the upper portions of which are pivotable with the lower portion in the vertical direction as the center of oscillation rotation and in contact with the side portion of the arch 9 in the width direction B, and oscillation units 222a . 222b . 242a and 242b that are capable of the rear alignment plates 221a and 221b as well as the front alignment plates 241a and 241b in the width direction B of the sheets 9 to oscillate.

Accordingly, for example, the front alignment unit oscillates 240a only upper sections of the front registration plate 241a With the lower portion in the vertical direction as Oszillationsdrehpunkt, whereby the oscillation unit 242a the sections of the front alignment plate 241a which are to be oscillated, thereby reducing the inertial mass and the oscillation cycle of the front alignment plate 241a can be made faster. Accordingly, the number of times to press the sheets 9 be increased in the width direction B and the sheet alignment performance of the sheet 9 can be improved. In addition, the oscillation distance of the front alignment plate becomes 241a larger at the upper end portion side in the vertical direction, which is in contact with the sheets 9 device, whereas the lower end section, in contact with the arches 9 gets on the discard pile board 23 have accumulated, becomes shorter, so that the widthwise position of the falling bows 9 can be safely aligned while applying unnecessary vibration to the sheets 9 laying on the discard pile board 23 are stacked, prevented and damage the bows 9 is prevented. As a result, both an improvement in the sheet aligning performance and damage prevention of the sheets 9 be achieved, ie a prevention of a pressure barrier.
