Tension is applied to the continuous paper W1 traveling in the inkjet printing units 13 , 14 , and the continuous paper W1 is sent out to the subsequent folding unit 16 .

The folding unit 16 has a paper guide roller 161, an angle rod 162, two sets of clamping rollers H1, H2, a saw body I, a folding body J, a clamp body K, a guide belt L, an impeller M, a conveyor N, and a paper guide Parts G1, G2, G3 and guide rollers R61~R64.

Specifically, the printed continuous paper W1 is wound around the driven and rotated delivery roller 161 by the guide rollers R61 and R62 , and then drawn and guided to the upper part of the folding unit 16 . Then, the orientation of the continuous paper W1 is changed by 90 degrees in the horizontal direction by the angle lever 162, and is guided to the pinch roller H1 by the guide rollers R63 and R64.

The pinch rollers H1 and H2 are arranged vertically below the guide roller R63, and are respectively composed of a pair of left and right rollers Ha and Hb that are driven to rotate in opposite directions. The rollers Ha and Hb are formed with pressing portions having an outer shape larger than other parts in the vicinity of both ends in the width direction of the continuous paper W1 passing between them. The vicinity of both ends in the width direction of the continuous paper W1 is sandwiched with an appropriate pressing force by the pressing portions of the rollers Ha and Hb of the pinch rollers H1 and H2, and the continuous paper W1 is sent out from the pinch roller H2 arranged on the lower side to the fold. Between the page body J and the holder body K.

The saw main body I and the hinge main body J are arranged so that the axis of the hinge main body J is slightly higher than the axis of the saw main body I, and a small gap is formed between the peripheral surfaces of the saw main body I and the hinge main body J. Then, the folding main body J and the saw main body I are driven to rotate in opposite directions, and the continuous paper W1 fed out from the pinch roller H2 enters the folding main body J and the saw main body I along the substantially tangential direction of the folding main body J. between.

The folder main body K is arranged on the opposite side of the saw main body I beside the folding main body J, and the axis center of the folder main body K is slightly higher than the axis center of the folding main body J, between the folder main body K and the folding main body J Small gaps are formed between the peripheral surfaces. Furthermore, the adapter main body K is driven to rotate in the direction opposite to the rotation direction of the hinge main body J. As shown in FIG.

3A and 3B are enlarged views of the Z portion of FIG. 2 , which are schematic cross-sectional views of the saw main body I, the hinge main body J, and the clamp main body K.

The saw main body I has a saw blade device I1. On the other hand, the saw blade device I1 includes a saw blade I11 and a paper pressing member I12. The saw blade I11 is a sawtooth with a thin mountain-shaped blade tip, and the blade tip protrudes radially outward from the peripheral surface of the saw body I in a direction parallel to the axis of the saw body I. The pressing piece I12 is an elastic body arranged adjacent to the saw blade I11 on both sides of the saw blade I11. The saw blade seat J1, which is set on the main body K of the clamping body K described later, is in contact with the pressing piece I12 as the main body rotates. In the opposite position, the continuous paper W1 is sandwiched between the saw blade seat J1 and the paper presser I12 with the help of the elastic force of the paper presser I12, and the tip of the saw blade I11 sinks into the saw blade seat J1 by 1 to 2 mm, so as to be parallel The continuous paper W1 is cut in the width direction. The length (cutting length) of the continuous paper W1 cut by the saw main body I per rotation is the horizontal length of two pages of the newspaper produced by the newspaper production device described later.

The perimeter of the folding main body J is twice the cutting length of the continuous paper W1, the saw blade seat J1, the needle device J2 as a holding mechanism, and the insertion blade device J3 as a folding blade mechanism are located near the surrounding surface of the folding main body J respectively. Two are arranged equally, and among them, the needle device J2 holds paper (continuous paper W1 or the sheet made by cutting the continuous paper W1. The following is the same.) on the outer peripheral surface of the folding main body J, and the insertion blade device J3 holds the paper. The pieces on the outer peripheral surface of the hinge main body J protrude outward in the radial direction.

The saw blade holder J1 is made of rubber with appropriate hardness, and faces the saw blade device I1 of the saw main body I, and the continuous paper W1 is sandwiched between the saw blade holder J1 and the saw blade device I1 to cut it.

In the direction of rotation of the folder body J, the needle device J2 is arranged immediately behind the position where the saw blade I11 of the saw blade device I1 cooperates with the saw blade holder J1 to cut the continuous paper W1. In one needle device J2, a plurality of needles J21 that can move in and out with respect to the peripheral surface of the folding body J are arranged at appropriate intervals in the width direction of the continuous paper W1. And, by making the needle J21 protrude several millimeters from the peripheral surface of the folder main body J, along with the rotation of the folder main body J, the continuous paper W1 is pierced immediately before the continuous paper W1 is cut by the saw blade I11, and the piercing is cut. The leading end of the continuous paper W1 is held, and the continuous paper W1 is wound around the folding body J while being pulled. Then, the needle J21 is pulled in from the peripheral surface of the folder main body J at an appropriate timing, and the needle J21 is pulled out from the sheet wound and held on the folder main body J so as not to hinder the transfer of the paper to the adapter main body K. In addition, a relief groove is formed on the main body K of the clamp to avoid interference with the needle J21, and the hardness of the pressing member I12 of the saw main body I is such that the needle J21 can easily penetrate.

The insertion blade device J3 has an insertion blade J31 that is a thin plate that can move in and out with respect to the peripheral surface of the folding main body J in the entire width direction of the continuous paper W1, and the insertion blade J31 is provided toward a position where the continuous paper W1 is cut. (2 places on the peripheral surface of the hinge main body J) The middle position protrudes. By protruding the insertion blade J31 from the peripheral surface of the folder main body J at an appropriate timing, the sheet wound on the folder main body J by the needle J21 is inserted into the anchor device K1 provided on the adapter main body K described later. Between the splints K11 and K12.

Next, the circumference of the main body K of the clamp is twice the cutting length, and two clamping devices K1 are equally arranged near the circumference.

The clamping device K1 has two adjacent clamping plates K11, K12. The clamping plate K11 is installed and fixed on the clamping body K, the clamping plate K12 swings around the swing axis K120, and the edge of the clamping plate K12 can approach or separate from the edge of the clamping body K relative to the edge of the clamping plate K11. And, in the state where the edge of the anchor plate K11 and the edge of the anchor plate K12 are separated, the insertion edge J31 of the hinge body J is connected between the edge of the anchor plate K11 and the edge of the anchor plate K12 by the rotation of the adapter body K. When facing each other, by protruding the insertion edge J31, the sheet wound on the peripheral surface of the hinge main body J is inserted between the jaws K11, K12, and then the jaws K12 move toward the direction in which the edge of the jaws K11 contacts the edge of the jaws K11. Swing, the edge of the clamping plate K11 and the edge of the clamping plate K12 clamp and hold the piece inserted through the insertion edge J31. The sheet held by the edge of the hinge plate K11 and the edge of the hinge plate K12 leaves a crease at the held position, and is wound on the leading side of the folder body J by the needle J21 pulled into the folder body J The end is released from the hinge main body J, pulled from the hinge main body J to the holder main body K along the paper guide G1, and then, the trailing side of the bitten position is wound on the holder main body K.

The guide belt L is guided by a plurality of pulleys including pulleys driven to rotate, and is an endless belt partially wound around the main body K of the adapter. Taking the creases formed by the adapter plates K11, K12 as a precedent, the sheet wound on the adapter body K is sandwiched between the guide belt L and the peripheral surface of the adapter body K, whereby half of the folded sheet and The other half overlaps towards its two cutting edges, thereby forming the newspaper signature Pf1, and cooperates with the holder body K to transport the newspaper signature Pf1 to the top of the impeller M.

From the position opposite to the position between the insertion blade J31 and the clamping plates K11, K12, the clamping main body K rotates more than half a turn and rotates forward, and the position where the newspaper folded signature Pf1 is clamped reaches before the front end of the paper guide G2. The clamping plate K12 swings in a direction in which its edge is separated from the edge of the clamping plate K11, so that the newspaper signature Pf1 is released from the clamping main body K.

The newspaper signature Pf1 released from the adapter main body K is guided between the vane M1 and the vane M1 of the impeller M by the paper guide G2 and the guide belt L traveling away from the peripheral surface of the adapter main body K.

The impeller M is driven to rotate so as to advance a distance corresponding to the distance between the blade M1 and the distance between the blades M1 during the one-half turn of the chuck main body K, and the impeller M is transported at a speed equal to the speed of the continuous paper W1. The newspaper signature Pf1 is partially accommodated between the blades M1 and M1, and the newspaper signature Pf1 is decelerated. Then, when the newspaper folded sheet Pf1 accommodated between the blades M1 and the blades M1 moves all the way to the lower side of the impeller M, it is pushed out from between the blades M1 and the blades M1 by the paper guide G3, and is discharged to a ratio of the continuous paper W1. The traveling speed is low on the conveyor N driven, and arranged in scales in which a part of the newspaper signature Pf1 overlaps.

The newspaper signature Pf1 carried out by the conveyor N is adjusted to a desired shipping posture by a post-processing device not shown.

In addition, the rotation speeds of the folding main body J and the clamping main body K are equal. In addition, the saw main body I rotates at twice the rotational speed of the folding main body J and the clamping main body K, so that the saw blade device I1 of the saw main body I and the The saw blade seat J1 of the folding body J, the insertion blade J31 of the folding body J, and the anchor plates K11, K12 of the chucking body K are synchronously driven in such a way that they face each other through rotation.

In the newspaper producing device 1 shown in FIG. 1, in the traveling path of the continuous paper W1, the traveling direction of the continuous paper W1 is changed by 90 degrees in the horizontal direction by the angle lever 162 of the folding unit 16, so that the newspaper signature Pf1 Carried out from the conveyor N to the direction at right angles to the advancing direction of the continuous paper W1 advancing in the newspaper making device 1, but also can have no angle bar, and the newspaper folded signature Pf1 is carried out from the conveyor N to the direction at right angles to the continuous paper W1 in the newspaper making device 1. In the same direction as the traveling direction of the continuous paper W1 traveling inside.

Next, the process of producing a vertically written 8-page newspaper by the above-mentioned newspaper producing apparatus 1 will be described.

4 is a simplified perspective view schematically showing the path of the printed continuous paper W1 forming a newspaper signature Pf1. FIG. Overlapping staggered perspective views.

The width of the continuous paper W1 is equal to the longitudinal length of the newspaper to be produced. In addition, in FIG. 4, the edge e1 of the continuous paper W1 (in the structure of the newspaper production apparatus 1 shown in FIG. 1, in FIG. 1, the front side of the continuous paper W1 passing through the inkjet printing units 13, 14) is The upper side of the newspaper page.

The continuous paper W1 that passes through the feeding unit 12 from the paper supply unit 11 and then passes through the first inkjet printing unit 13, on the front side Fw, prints the layout of the fifth page as the first time, and then prints it as the second time. Page 4 layout. The layout of page 5 is printed again as the third time, and then the layout of page 4 is printed as the fourth time. Next, the layout of the seventh page is printed as the fifth time, and the layout of the second page is printed as the sixth time. The layout of page 7 is printed again as the seventh time, and then the layout of page 2 is printed as the eighth time. That is to say, the layout is repeatedly printed in the order of the 5th, 4th, 5th, 4th, 7th, 2nd, 7th, and 2nd pages. The continuous paper W1 that has been printed in this way on the front side Fw continues to print the layout of the 6th page on the reverse side Bw of the layout of the 5th page that has been printed by the second inkjet printing unit 14. On the reverse side Bw of the layout of the first page, the layout of the third page is continuously printed, on the reverse side Bw of the layout of the seventh page, the layout of the eighth page is continuously printed, and on the reverse side Bw of the layout of the second page. Continue to print the page 1 layout. That is, it is integrated with the layout acquisition position printed on the front Fw, and repeats in the order of pages 6, 3, 6, 3, 8, 1, 8, and 1 (page numbers shown in parentheses in FIG. 4 ). print layout.

The continuous paper W1 printed on both sides is guided to a folding unit 16 via a delivery unit 15 . The continuous paper W1 drawn to the upper part of the folding unit 16 by the threading roller 161 is changed in the horizontal direction by 90 degrees by the angle bar 162, and is guided to the pinch roller H1 by the guide rollers R63 and R64. The rolls Ha and Hb of the pinch roll H1 pinch both ends of the continuous paper W1 in the width direction, that is, the upper and lower margins of the layout, with an appropriate pressing force by the pressing portion, and are sent out to the pinch roll H2. Like the pinch roller H1, the pinch roller H2 pinches both ends of the continuous paper W1 in the width direction by the pressing portion with an appropriate pressing force, and sends it out between the folder main body J and the saw main body I. Since the continuous paper W1 is fed between the two sets of rollers Ha and Hb that are driven to rotate, the variation in tension caused by the subsequent cutting between the folding main body J and the saw main body I will not affect the continuous paper W1. On the upstream side of the traveling path, and the rollers Ha and Hb sandwich the blank part of the plate, the ink on the plate will not be transferred to the pressing part of the rollers Ha and Hb, and the plate will not be stained.

The continuous paper W1 sent downward from the pinch roller H2 enters between the folder main body J and the saw main body I. With the rotation of the two main bodies, the needle J21 protruding from the surface of the folding main body J pierces through the back side Bw from the front side Fw of the continuous paper W1, and the paper presser I12 sandwiches the continuous paper W1 between the paper presser I12 and the saw blade seat J1 In between, the saw blade I11 sinks into the saw blade seat J1 to cut the continuous paper W1. Regarding the position to be cut, the printing timing of the inkjet printing units 12, 13 is aligned with the rotation phase of the folding main body J and the saw main body I, and the fourth page of the layout printed on the front surface Fw and subsequent printing are repeatedly cut in sequence. between the 5th page (between the 3rd page printed on the reverse side Bw and the 6th page printed thereafter (the position indicated by the arrow a in Figure 4)), the 4th page printed on the front side Fw and the 6th page printed thereafter Between the 7th page printed later (between the 3rd page printed on the back side Bw and the 8th page printed later (the position indicated by the arrow b in Fig. 4)), the 2nd page printed on the front side Fw between page 1 and the 7th page printed later (between the 1st page printed on the back side Bw and the 8th page printed thereafter (the position indicated by the arrow c in FIG. 4 )) and the layout printed on the front side Fw Between the 2nd page and the 5th page printed thereafter (between the 1st page printed on the layout of the reverse side Bw and the 6th page printed thereafter (the position indicated by the arrow d in FIG. 4 )).

The continuous paper W1 is sandwiched between the platen I12 and the saw blade holder J1, so that when the saw blade I11 sinks into the saw blade holder J1 and cuts the continuous paper W1, the cutting position will not deviate.

In addition, the paper that has been cut into a sheet has the needle J21 pierced at the leading end thereof, so that the needle J21 remains on the periphery of the hinge body J until the needle J21 is pulled from the periphery of the hinge body J and pulled out from the sheet. face.

In this way, for the first time, a sheet with pages 5 and 4 printed on the front Fw and pages 6 and 3 printed on the back Bw is produced, and a sheet with pages 5 and 4 printed on the front Fw and pages 4 and 3 are also produced for the second time. On the reverse side Bw, the sheets with the layouts of pages 6 and 3 are printed for the third time, and the sheets with the layouts of pages 7 and 2 printed on the front Fw and pages 8 and 1 printed on the reverse side Bw are made for the third time, and then, for the fourth time, This time, a sheet with pages 7 and 2 printed on the front Fw and pages 8 and 1 printed on the back Bw is also produced, and so on.

On the other hand, the leading end of the first piece p1 cut from the continuous paper W1 is pulled by being pierced by the needle J21, and is held in a half state of being wound around the main body J of the folder. Even if the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge main body J under the piece p1 reaches a position facing between the anchor plates K11 and K12 of the adapter main body K, the insertion edge J31 is not protruded, and , nor pull in the needle J21 at the leading end of the piercing sheet p1. That is, the first sheet p1 is pulled and held by the needle J21, and the leading end portion again faces a position overlapping with the traveling path of the continuous paper W1.

In addition, the leading end of the continuous paper W1 serving as the second sheet is also pierced by the needle J21 and wound around the peripheral surface of the hinge main body J. As shown in FIG.

The needle J21 that pierces through the leading end of the first sheet p1 for holding and pulling along with the rotation of the folding body J further penetrates the continuous paper W1 sent from the pinch roller H2, and the saw blade device I1 will The continuous paper W1 sandwiched between the saw blade device I1 and the saw blade holder J1 is cut to separate the trailing end of the second sheet p2 from the leading end of the continuous paper W1 which becomes the third sheet (see FIG. 3A ). Then, the continuous paper W1 superimposed on the outside of the first sheet p1 to become the third sheet is also pulled by the needle J21 and wound around the hinge main body J. As shown in FIG.

During this period, the second piece p2 cut from the continuous paper W1 rotates together with the main body J of the main body of the main body of the main body of the main body of the folding paper J in a state of being pulled by the needle J21 to be wound and held by half of the circumference of the main body of the main body of the folding paper. And, when the insertion blade J31 in the state of being pulled in from the peripheral surface of the hinge main body J under the sheet p2 reaches a position facing between the adapter plates K11 and K12 of the adapter main body K, the insertion blade J31 does not protrude, and, The needle J2 that pierced the leading end of the sheet p2 is not pulled in either. That is, the second sheet p2 is also pulled by the needle J21, and the leading end portion again faces a position overlapping with the traveling path of the continuous paper W1.

The needle J21 that pierces the leading end of the second sheet p2 to hold and pull it further penetrates the continuous paper W1 sent from the pinch roller H2 along with the rotation of the folding main body J, and the saw blade device I1 The continuous paper W1 sandwiched between the saw blade device I1 and the saw blade holder J1 is cut to separate the trailing end of the third sheet from the leading end of the fourth sheet of the continuous paper W1. Then, the continuous paper W1 stacked on the outside of the second sheet p2 to form a fourth sheet is also pulled by the needle J21 and wound around the hinge main body J. As shown in FIG.

Next, the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge main body J under the overlapped first piece p1 and the third piece is about to reach between the jaw plates K11 and K12 of the main body K. Before the position of , the insertion blade device J3 starts to protrude the insertion blade J31, and at the same time, the needle device J2 that pierces the leading end of the first sheet p1 and the third sheet pulls the needle J21 in.

In this way, on the peripheral surface of the main body J of the folding page, the centers of the two sheets with the third sheet superimposed on the outside of the first sheet p1 are held by the edge of the splint K11 and the edge of the splint K12. The position forms the crease. Then, the two sheets held by the edge of the clamping plate K11 and the edge of the clamping plate K12 are sandwiched by the clamping main body K and the guide belt L, so that the overlapped and creased sheets are on the peripheral surface of the folding main body J. The upper half on the leading side and the half on the trailing side of the crease overlap to form a newspaper signature Pf1 in which pages 1 to 8 are printed (see FIG. 5 ).

The newspaper fold Pf1 is transported to the upper part of the impeller M by the clamping main body K and the guide belt L. Before the position where the newspaper fold Pf1 is clamped reaches the paper guide G2, the clamping device K1 makes the clamping plate K12 leave the clamping plate K12 to its edge. The direction of the edge of the clamping plate K11 swings, so that the newspaper folded signature Pf1 is released from the clamping plate K11 and the clamping plate K12, and is thrown into the blade M1 and the blade M1 of the impeller M through the paper guide G2 and the guide belt L extending along the paper guide G2 between.

When the newspaper fold Pf1 put into and accommodated between the blade M1 and the blade M1 is rotated so that the accommodated position is at the lower side, the newspaper fold Pf1 is discharged from between the blade M1 and the blade M1 to the conveying position. on machine N.

On the other hand, the continuous paper W1 overlapping the outside of the second sheet p2 and becoming the fourth sheet is also pulled by the needle J21 and wound around the folding body J, and the saw blade device I1 is sandwiched between the saw blade device I1 and the saw. The continuous paper W1 between the blade blocks J1 is cut, and the trailing end of the fourth sheet is separated from the continuous paper W1. Then, under the overlapped second piece p2 and the fourth piece, the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge main body J is about to reach between the jaw plates K11 and K12 of the main body K. Before the position, the insertion blade device J3 starts to protrude the insertion blade J31, and at the same time, the needle device J2 piercing the leading end of the second sheet p2 and the fourth sheet pulls the needle J21 in.

Immediately after the above-mentioned operations are performed, the insertion blade J31 faces between the jaws K11 and K12 of the main body K, and the second piece p2 and the fourth piece are inserted between the jaws K11 and K12. Immediately after the insertion, the clamping device K1 makes the clamping plate K12 swing around the swing axis K120, and the second piece p2 and the fourth piece are held by the edge of the clamping plate K11 and the edge of the clamping plate K12, so that the second The first piece p2 and half of the leading side of the fourth piece are pulled from the hinge body J to the holder body K, and the second piece p2 and the half of the trailing side of the fourth piece are wound around the holder body K .

The insertion edge J31 inserts the second piece p2 and the fourth piece between the clamping plates K11 and K12, and then is pulled into the folding body J so as not to hinder the movement of the paper pulled from the folding body J to the clamping body K .

In this way, on the peripheral surface of the main body J of the folding page, the centers of the two sheets with the fourth sheet superimposed on the outside of the second sheet p2 are held by the edge of the splint K11 and the edge of the splint K12. The position forms the crease. Then, the two sheets held by the edge of the clamping plate K11 and the edge of the clamping plate K12 are sandwiched by the clamping main body K and the guide belt L, so that the overlapped and creased sheets are on the peripheral surface of the folding main body J. The upper half on the leading side and the half on the trailing side of the crease are overlapped to form a newspaper with printed pages 1 to 8 in the same way as the newspaper signature Pf1 formed by the first sheet p1 and the third sheet described above. Fold post Pf1.

The produced newspaper signature Pf1 formed of the second sheet p2 and the fourth sheet is discharged onto the conveyor N through the impeller M in the same way as the newspaper signature Pf1 formed of the first sheet p1 and the third sheet. By repeating the above-mentioned operations, eight pages of newspapers are continuously produced.

Therefore, these structures are those in which "continuous paper WI" in the above description is replaced with "overlaid continuous paper W21 and continuous paper W22", and "newspaper signature Pf1" is replaced with "newspaper signature Pf2". Description omitted.

Next, the process of producing a newspaper with 16 vertical pages by the newspaper producing device 2 will be described.

Fig. 8 is a perspective view schematically showing the path of the newspaper signature Pf2 formed by the printed continuous paper W2, and Fig. 9 is a diagram showing the overlapping of the newspaper signature Pf2 in order to easily understand the page structure of the newspaper signature Pf2 in Fig. 8 stereogram.

The width of the continuous paper W2 is equal to twice the longitudinal length of the newspaper. In addition, in the structure of the newspaper production apparatus 2, the position where the continuous paper W2 is cut by the paper cutting mechanism E and becomes an edge, that is, the widthwise center of the continuous paper W2 (the position indicated by the dotted line e2 in FIG. 8 ) is On the lower side of the newspaper page, both ends in the width direction of the continuous paper W2 (positions denoted by e3 and e4 in FIG. 8 ) become the upper side of the newspaper page.

The continuous paper W2 that passes through the feeding unit 22 from the paper supply unit 21 and then passes through the first inkjet printing unit 23, on its front face Fw, is on the front side of the printing width direction (cut by the paper cutting mechanism E) as the first time. The side that becomes the continuous paper W21) prints the layout of the ninth page, and prints the layout of the twelfth page on the inner side in the width direction (the side that becomes the continuous paper W22 cut by the cutter mechanism E), and then prints the layout of the twelfth page as the second time on the width The layout of the eighth page is printed on the front side in the direction of the eye, and the layout of the fifth page is printed on the inside in the width direction.

As the third time, the layout of page 9 is printed on the front side of the width direction again, and the layout of page 12 is printed on the inside of the width direction, and then the layout of page 8 is printed on the front side of the width direction as the fourth time, and the layout of page 8 is printed on the front side of the width direction. The layout of page 5 is printed on the inside.

Then, as the fifth time, the layout of page 13 is printed on the front side in the width direction, and the layout of page 16 is printed on the inside in the width direction, and the layout of page 4 is printed on the front side in the width direction as the sixth time. The layout of page 1 is printed on the inside of the direction.

Print the layout of page 13 again on the front side in the width direction as the seventh pass, print the layout of page 16 on the inside in the width direction, and then print the layout of page 4 on the front side in the width direction as the eighth pass, and print the layout on the inside in the width direction Layout for printing page 1.

That is, pages 9, 8, 9, 8, 13, 4, 13, 4 on the front side in the width direction, and pages 12, 5, 12, 5, 16, 1, 16, 16 on the inside in the width direction. The layout is printed repeatedly in the order of 1 page. The continuous paper W2 printed in this way on the front Fw is passed through the second inkjet printing unit 24 to continue printing the layout of the 10th page on the reverse side Bw printed with the layout of the 9th page, and printing the layout of the 12th page. Continue printing the layout of the 11th page on the reverse side Bw of the layout, then continue printing the layout of the 7th page on the reverse side Bw of the layout of the printed page 8, and continue printing on the reverse side Bw of the layout of the 5th page For the layout of page 6, continue to print the layout of page 14 on the reverse side Bw of the layout of page 13, continue to print the layout of page 15 on the reverse side Bw of the layout of page 16, and then print The layout of the third page is continuously printed on the reverse side Bw on which the layout of the fourth page is printed, and the layout of the second page is continuously printed on the reverse side Bw on which the layout of the first page is printed. That is to say, it is aligned with the layout acquisition position printed on the front side Fw, on the front side in the width direction of the back side Bw in the order of the 10th, 7th, 10th, 7th, 14th, 3rd, 14th, and 3rd pages, and on the inner side in the width direction according to the order of the 10th, 7th, 10th, 7th, 14th, 3rd, 14th, 3rd pages. 11, 6, 11, 6, 15, 2, 15, 2 pages (the page numbers in parentheses are shown in FIG. 8 ) are repeatedly printed on the layout.

The continuous paper W2 printed on both sides is guided to a folding unit 26 via a delivery unit 25 .

The continuous paper W2 is drawn to the upper part of the former F1 by the idler E2 serving also as the delivery roller of the paper cutting mechanism E, and is cut at the center in the width direction by the paper cutter E1 to form the continuous paper W21 and the continuous paper W22. The continuous paper W21 and the continuous paper W22 change their direction by 90 degrees along the inclined edge of the triangular plate F1, and then are superimposed by the superposition rollers F2 and F2, and then go toward the pinch roller H1. The rolls Ha and Hb of the pinch roll H1 pinch both ends of the overlapped continuous paper W21 and W22 in the width direction, that is, the upper and lower margins of the layout, with an appropriate pressing force through the pressing part, and send it out to the pinch roll H2. Like the pinch roller H1, the pinch roller H2 clamps both ends of the overlapped continuous paper W21 and continuous paper W22 in the width direction with an appropriate pressing force through the pressing part, and sends it out between the folding main body J and the clamping main body K. between. The continuous paper W21 and the continuous paper W22 are fed out between the two sets of rollers Ha and Hb driven to rotate, so that fluctuations in tension caused by cutting between the subsequent folding main body J and saw main body I will not affect them. The upstream side of the travel path of the continuous paper W21 and the continuous paper W22. In addition, since the margins of the layout are sandwiched, the ink on the layout will not be transferred to the pressing parts of the rollers Ha and Hb, nor will it be transferred between the continuous paper W21 and the continuous paper W22, and the layout will not be stained. .

The continuous paper W21 and the continuous paper W22 sent downward from the pinch roller H2 enter between the folder main body J and the saw main body I. As the folder body J and the saw body I rotate, the needles J21 protruding from the surface of the folder body J pierce the back side Bw from the front side Fw of the continuous paper W21, and then pierce the front side Fw from the back side Bw of the continuous paper W22, and The paper presser I12 clamps the continuous paper W21 and the continuous paper W22 between the paper presser I12 and the saw blade seat J1, and the saw blade I11 sinks into the saw blade seat J1 to cut the continuous paper W21 and the continuous paper W22.

Regarding the position to be cut, by matching the printing timing of the inkjet printing units 22 and 23 with the rotation phases of the folding main body J and the saw main body I, the positions of the layout printed on the front surface Fw of the continuous paper W21 are sequentially and repeatedly cut. Between the 8th page and the 9th page printed thereafter (between the 7th page of the layout printed on the back side Bw and the 10th page printed thereafter), simultaneously cut the 1st page of the layout printed on the front side Fw of the continuous paper W22. Between the 5th page and the 12th page printed later (between the 6th page printed on the reverse side Bw and the 11th page printed later (the position indicated by the arrow a in Fig. 8)), cut on the continuous paper W21 Between the 8th page printed on the front side Fw and the 13th page printed thereafter (between the 7th page printed on the back side Bw and the 14th page printed thereafter), simultaneously cut the front side of the continuous paper W22 Between the 5th page printed on Fw and the 16th page printed thereafter (between the 6th page printed on the reverse side Bw and the 15th page printed thereafter (position indicated by arrow b in Fig. 8)) , cutting between the 4th page of the layout printed on the front side Fw of the continuous paper W21 and the 13th page printed thereafter (between the 3rd page of the layout printed on the back side Bw and the 14th page printed thereafter), and cutting at the same time Between the 1st page of the layout printed on the front side Fw of the continuous paper W22 and the 16th page printed thereafter (between the 2nd page of the layout printed on the back side Bw and the 15th page printed thereafter (arrows in FIG. 8 The position indicated by c)) and between the 4th page of the layout printed on the front side Fw of the continuous paper W21 and the 9th page printed thereafter (between the 3rd page of the layout printed on the back side Bw and the 10th page printed thereafter) between the first page of the layout printed on the front side Fw of the continuous paper W22 and the subsequent printed page 12 (between the second page of the layout printed on the back side Bw and the subsequent printed page 11 ( The position indicated by the arrow d in Fig. 8)).

The overlapped continuous paper W21 and continuous paper W22 are sandwiched between the platen I12 and the saw blade holder J1. Therefore, when the saw blade I11 sinks into the saw blade holder J1 while cutting the continuous paper W21 and the continuous paper W22, the cutting The position will not be offset.

In addition, the paper that is cut into sheets has the needle J21 pierced at the leading end thereof, so that the needle J21 is pulled from the peripheral surface of the hinge body J and pulled out from the sheet, and remains on the hinge body J. Zhou surface.

In this way, for the first time, on the front side Fw of the continuous paper W21, pages 9 and 8 and pages 10 and 7 are printed on the back side Bw, and pages 12 and 5 are printed on the front side Fw of the continuous paper W22. And on the back side Bw, the sheets with the layout of the 11th and 6th pages are printed on the back side Bw respectively, and are made by overlapping the back side Bw. In the second time, the 9th and 8th pages are printed on the front side Fw of the continuous paper W21 and the 1st page is printed on the back side Bw. Sheets with page 10 and page 7 layouts and sheets with pages 12 and 5 printed on the front side Fw of the continuous paper W22 and pages 11 and 6 printed on the back side Bw are respectively superimposed on the back side Bw. The continuous paper W21 has pages 13 and 4 printed on the front Fw and pages 14 and 3 printed on the back Bw three times, and continuous paper W22 has pages 16 and 1 printed on the front Fw and printed on the back Bw three times. Sheets with the 15th and 2nd page layouts are superimposed on the back side Bw respectively, and then, in the fourth time, the 13th and 4th pages are printed on the front side Fw of the continuous paper W21 and the 14th and 3rd pages are printed on the back side Bw The sheets of the layout of the continuous paper W22 are overlapped with the sheets having the 16th and 1st pages printed on the front Fw and the 15th and 2nd pages printed on the back Bw respectively facing the back Bw, and so on.

On the other hand, the leading end of the first sheet (two sheets) cut from the continuous paper W21 and the continuous paper W22 is pierced by the needle J21 and drawn, and is wound and held around the folding main body J in half. In one of the states, even if the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge main body J under the first piece (2 sheets) reaches between the jaw plates K11 and K12 of the main body K position, the insertion blade J31 does not protrude, and the needle J21 that pierces the leading end of the first sheet (2 sheets) is not pulled in, that is, the first sheet (2 sheets) is still pulled and held by the needle J21 Then, the leading end portion again faces a position overlapping the travel paths of the continuous paper W21 and the continuous paper W22.

In addition, the leading ends of the continuous paper W21 and the continuous paper W22 serving as the second sheet (two sheets) are also pierced by the needle J21 and wound around the peripheral surface of the needle body J.

The needle J21 that pierces the leading end of the first sheet (two sheets) for holding and pulling further penetrates the continuous paper W21 and the continuous paper W22 repeatedly fed from the pinch roller H2 by the rotation of the folding main body J, and The saw blade device I1 cuts the continuous paper W21 and the continuous paper W22 sandwiched between the saw blade device I1 and the saw blade seat J1, so that the trailing end of the second sheet (2 sheets) and the continuous sheet of the third sheet The leading ends of the paper W21 and the continuous paper W22 are separated. Then, the continuous paper W21 and the continuous paper W22 which are stacked on the first sheet (two sheets) and become the third sheet are also pulled by the needle J21 and wound around the main body J of the folder.

During this period, the second sheet (two sheets) cut from the continuous paper W21 and the continuous paper W22 is pulled by the needle J21 to be wound and held in half of the periphery of the folding main body J, Rotate together with the hinge body J. And, when the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge main body J under the second piece (2 sheets) reaches the position facing between the jaw plates K11 and K12 of the main body K, the insertion blade J31 is inserted. The blade J31 does not protrude, and does not pull in the needle J21 that pierces the leading end of the second sheet (2 sheets), that is, the second sheet (2 sheets) is also pulled by the needle 21, and the leading end again faces and continues A position where the travel paths of the paper W21 and the continuous paper W22 overlap.

The needle J21 that pierces the leading end of the second sheet (two sheets) for holding and pulling, further pierces the continuous paper W21 and the continuous paper W22 sent from the pinch roller H2 by the rotation of the folding main body J, And the saw blade device I1 cuts the continuous paper W21 and the continuous paper W22 sandwiched between the saw blade device I1 and the saw blade seat J1 to make the trailing end of the third sheet (2 sheets) and the end of the fourth sheet. The leading ends of the continuous paper W21 and the continuous paper W22 are separated. Then, the continuous paper W21 and the continuous paper W22 stacked on the outside of the second sheet (two sheets) to form the fourth sheet are also pulled by the needle J21 and wound around the main body J of the folder.

Next, the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge main body J under the overlapped first piece (2 pieces) and the third piece (2 pieces) is about to reach the joint with the holder main body K. Before the facing position between the splints K11 and K12, the insertion blade device J3 starts to protrude the insertion blade J31, and roughly at the same time, the needles at the leading ends of the first piece (2 pieces) and the third piece (2 pieces) are pierced. Device J2 pulls needle J21 in.

Immediately after the above-mentioned action is performed, the insertion blade J31 faces between the clamping plates K11 and K12 of the clamping main body K, and the first piece (2 pieces) and the third piece (2 pieces) are inserted into the clamping plates K11, K12 between. Immediately after insertion, the clamping device K1 makes the clamping plate K12 swing around the swing axis K120, and holds the inserted first piece (2 sheets) and the third piece through the edge of the clamping plate K12 and the edge of the clamping plate K11 (2 sheets), thereby pulling the leading side half of the first sheet (2 sheets) and the third sheet (2 sheets) from the hinge body J to the holder body K, and, making the first sheet (2 sheets) sheet) and half of the trailing side of the third sheet (2 sheets) are wound around the main body K of the adapter.

The insertion blade J31 inserts the first sheet (2 sheets) and the third sheet (2 sheets) between the splints K11 and K12, and then is pulled into the main body J of the folding page, so as not to hinder the pulling from the main body J of the folding page to the hinge. Movement of the paper that clamps the main body K.

In this way, a third sheet (2 sheets) is overlapped on the first sheet (2 sheets), and the center of a sheet that overlaps 4 pages is held by the edge of the splint K11 and the edge of the splint K12. The position forms the crease. Then, the four sheets held by the edge of the clamping plate K11 and the edge of the clamping plate K12 are clamped by the clamping main body K and the guide belt L, so that the overlapped and creased sheets are on the peripheral surface of the folding main body J The half on the leading side and the half on the trailing side of the crease overlap to form a newspaper signature Pf2 (see FIG. 9 ) in which pages 1 to 16 are printed.

The newspaper fold Pf2 is transported to the upper part of the impeller M by the clamping body K and the guide belt L, the position where the newspaper fold Pf2 is clamped reaches before the paper guide G2, and the clamping device K1 makes the clamping plate K12 away from the clamping plate towards its edge The direction of the edge of K11 swings, so that the newspaper folded signature Pf2 is released from the clamping plate K11 and the clamping plate K12, and is thrown between the blades M1 and blades M1 of the impeller M through the paper guide G2 and the guide belt L extending along the paper guide G2 .

The newspaper signature Pf2 put in and accommodated between the blade M1 and the blade M1 is discharged from between the blade M1 and the blade M1 to the conveyance when the impeller M rotates so that the stored position becomes the lower side. on machine N.

On the other hand, the continuous paper W21 and the continuous paper W22, which are overlapped on the outside of the second sheet (2 sheets) and become the fourth sheet, are also pulled by the needle J21 and wound around the folding body J, and the saw blade device I1 clamps The continuous paper W21 and the continuous paper W22 between the saw blade device I1 and the saw blade seat J1 are cut, and the trailing end of the fourth sheet (2 sheets) is separated from the continuous paper W21 and the continuous paper W22. And, the insertion edge J31 in the state of being pulled in from the peripheral surface of the hinge body J under the overlapped second sheet (2 sheets) and the fourth sheet (2 sheets) is about to reach the engagement with the holder body K. Before the facing position between the splints K11 and K12, the insertion blade device J3 starts to protrude the insertion blade J31, and roughly at the same time, penetrates the front side of the second sheet (2 sheets) and the fourth sheet (2 sheets). Needle device J2 pulls needle J21 in.

Immediately after performing the above actions, the insertion edge J31 faces between the jaws K11 and K12 of the main body K, and inserts the second piece (2 pieces) and the fourth piece (2 pieces) into the jaws K11, K12 between. Immediately after the insertion, the clamping device K1 makes the clamping plate K12 swing around the swing axis K120, and the second piece (2 pieces) and the fourth piece inserted are held by the edge of the clamping plate K12 and the edge of the clamping plate K11 (2 sheets), thereby pulling the leading side half of the second sheet (2 sheets) and the fourth sheet (2 sheets) from the hinge body J to the holder body K, and, making the second sheet (2 sheets) One side of the trailing side of sheet) and the fourth sheet (2 sheets) are wound around the main body K of the holder.

The insertion edge J31 is pulled into the hinge body J after inserting the second piece (2 pieces) and the fourth piece (2 pieces) between the splints K11 and K12, so as not to hinder the pulling from the hinge body J to the Movement of the paper that holds the main body K.

In this way, on the peripheral surface of the folding main body J, a fourth sheet (2 sheets) is superimposed on the second sheet (2 sheets), so that the center of the sheet that overlaps 4 sheets is formed by the edge of the splint K11 and the splint. The edge of the K12 is bitten, forming a crease at the bitten position. In addition, the four sheets held by the edge of the clamping plate K11 and the edge of the clamping plate K12 are clamped by the clamping main body K and the guide belt L, so that the overlapping and creased sheets are folded on the peripheral surface of the folding main body J. The half on the leading side of the crease coincides with the half on the trailing side of the crease, which is the same as the above-mentioned newspaper fold Pf2 formed by the first sheet (2 sheets) and the third sheet (2 sheets), forming the printed first sheet. Newspaper folder Pf2 from pages 1 to 16.

The newspaper folder Pf2 formed by the second sheet (2 sheets) and the fourth sheet (2 sheets) and the newspaper sheet formed by the first sheet (2 sheets) and the third sheet (2 sheets) The posts Pf2 are the same, and are discharged to the conveyor N by the impeller M. By repeating the above-mentioned operations, 16 pages of newspapers are continuously produced.

In the newspaper making device 2 shown in FIG. 6, a paper cutting mechanism and a folding former mechanism as a overlapping mechanism are provided on the folding unit, but it is not limited to this, and it may also be provided in the traveling path of the printed continuous paper. The overlapping mechanism formed by combining the cutting mechanism C shown in Fig. 10 and two angle bars B and B cuts a continuous paper W2 in the continuous direction to form a continuous paper W21 and a continuous paper W22. The two edges of the paper W21 and the continuous paper W22 are aligned and overlapped, and then introduced into the folding unit (the arrows in FIG. 10 indicate the running direction of the continuous paper). In addition, in the structure of Fig. 10, in Fig. 10, the edge represented by the symbol d1 is the upper side of the newspaper layout printed on the continuous paper W21, and the edge represented by the symbol d2 is the upper side of the newspaper layout printed on the continuous paper W22. upper side.

Preferred embodiments of the present invention have been described above, but the technical scope of the present invention is not limited to the range described in the above-mentioned embodiments. Various changes and improvements can be made to the above-described embodiments.

For example, in the first and second embodiments, it has been described that a newspaper whose number of pages is twice that of continuous paper is produced by performing the following so-called "collect run" (collect run) in newspaper production. The process of forming newspapers from sheets, that is, every time the folding main body J rotates 2 times and each insertion blade J21 reaches a position facing between the clamping plates K11 and K12 of the main body K, the insertion of each insertion blade device J2 The blade J21 protrudes, and at approximately the same timing, the needle 111 of the needle device 11 on the leading side of the insertion blade J21 is pulled in at about 90 degrees, and by performing such an action, the paper is held on the rotating folding page. On the peripheral surface of the main body J, paper is piled up on the held paper to form a folded signature. However, according to the inkjet printing unit, it is possible to print a variety of arbitrary layouts in any order. Therefore, every time the folding body J rotates X times, the insertion blade J21 of each insertion blade device J2 is protruded and the needle device is moved. The needle I11 of I1 pulls in to hold and overlap the paper roll on the peripheral surface of the main body J of the folding page, thereby making it possible to produce a newspaper formed by sheets whose number of pages is X times the number of continuous paper pages.

In addition, newspaper signatures are not thrown between the blades of the rotating impeller while the sheets are held and overlapped on the peripheral surface of the folder main body, so newspaper signatures are arranged on the conveyor at unequal intervals. In order to arrange the newspaper sheets at equal intervals on the conveyor, it is only necessary to make the conveyor run intermittently or at a variable speed in accordance with the newspaper sheets discharged from the impeller. In addition, it is of course also possible to directly process the newspaper folds arranged on the conveyor at unequal intervals by the post-processing device.

Moreover, the folding unit 16 and the folding unit 26 of the first and second embodiments are so-called "clamp folding mechanisms" in which the clamping device K1 of the clamping main body K clamps the sheet and folds the sheet at the engaged position. ", but it may also be a folding unit of the so-called "leaf folding mechanism", that is, a pair of folding nip rollers are provided at the lower part of the folding main body, and the sheet is inserted through the folding blades protruding from the folding main body. The fold is sandwiched between the rollers to form the crease.

In addition, the folding main body J and the holder main body K of the folding unit 16 and the folding unit 26 are so-called "double main bodies" whose perimeter is twice the cutting length of the continuous paper cut parallel to the width direction, but also It can be that its circumference is 3 times or a multiple of more than 3 times of the cutting length.

In addition, in order to perform collation by printing with a rotary printing machine, the perimeter of the folding body needs to be an odd multiple of the cutting length, generally 3 or 5 times. This is because, in a rotary printing machine, two types of printing plates for printing different pages are installed on the main body of the printing plate having a circumference twice the cutting length for printing. Therefore, in the direction of travel of the continuous paper, Different pages that should overlap are alternately printed next to each other. Therefore, in the case where two different pages are to be superimposed on the main body of the folding page through the operation with collation, for example, by forming the main body of the folding page with three times the perimeter, it is possible to print the type of page on the first sheet. A fourth slice of a page of a different kind than the first slice overlaps. However, according to the inkjet printing unit, arbitrary various layouts can be printed in any order, so the perimeter of the folding body is not limited to an odd multiple of the cutting length, so the folding unit can be miniaturized.

[Third Embodiment]

Fig. 11 shows a newspaper producing device 3 of the third embodiment. The newspaper making device 3 is provided with a sheet making device S and a sheet accumulating device T between the upper part of the sending unit 15 of the newspaper making device 1 and the folding unit 16, and is provided with a continuous paper W1 that is set on the sending roller. The guide roller R after 151 guides the paper path to the sheet forming apparatus S, and the path of the printed continuous paper W1 passing through the folding unit 16 and the path passing through the sheet forming apparatus S can be selected. By passing the continuous paper W1 through the sheet forming device S, the continuous paper W1 can be cut into sheets and accumulated in the sheet stacking device T. FIG. Since various devices of the sheet forming device and the sheet stacking device are well known, descriptions of the sheet forming device S and the sheet stacking device T are omitted here. According to the newspaper making device 3 shown in FIG. 11, in addition to being able to make a newspaper signature by the folding unit 16, it is also possible to make a sheet of a predetermined cut length by guiding the continuous paper W1 to the sheet making device S. shaped prints.
