Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic paper splicing processing method and automatic paper splicing processing for pre-processing for paper splicing on newspaper printing webs and commercial printing webs such as magazines and books. Regarding the device.

[0002]

2. Description of the Related Art Generally, newspaper printing rolls and commercial printing rolls delivered to a printing plant are usually protected by covering the outer peripheral surface with a hump (lower grade paper). In order to perform automatic splicing of the rolls of paper in the paper section, a lump removal process and a pre-splicing process of the rolls of paper are performed in the printing plant.

[0003] Conventionally, the one-pitch removal processing of the paper roll is performed manually or by a one-pip cutting and peeling processing apparatus disclosed in Japanese Patent Laid-Open No. 63-277161. Further, the pretreatment for splicing the rolled paper is performed manually or in JP-A-63-2.
This is performed by the automatic paper splicing pretreatment device disclosed in Japanese Patent Publication No. 95354.

By the way, as shown in FIG. 29, in the pre-bonding process for the newspaper printing web P, the front end of the web P from which the hump has been removed is cut into a substantially V shape, and double-sided adhesive is applied to the front surface. The tape is attached to form the adhesive layer b for paper splicing, and the tip portion is attached to the outer surface of the paper roll P by the tab T. Further, as shown in FIG. 30, the pre-treatment for the splicing of the commercial printing web P is performed by cutting the front end of the web P from which the hump has been removed into a substantially trapezoidal shape, and attaching the double-sided adhesive tape to the surface of the front end. Thus, the adhesive layer b for paper splicing is formed, and the tip end portion is adhered to the outer surface of the paper roll P by a plurality of tabs T.

Thus, in the rotary press for printing, as shown in FIG.
As shown in, a new paper roll P that has been pretreated for paper splicing
Is mounted on the web support device 101 of the rotary press 100 (for newspapers or commercial), and is rotated at a constant circumferential speed with the web P being used, which is being fed to the rotary press 100 at a constant speed. When the trailing end of the web P is pressed against the beginning of the new web P, the end of the web P in use and the beginning of the new web P are attached and connected by the adhesive layer b for splicing the paper, and the tab T is formed. The start end portion of the new paper W that has been cut is continuously supplied to the rotary press 100. In FIG. 31, 102 is an arm of the paper roll support device 101, and 103 is a rotating shaft of the arm 102.

[0006]

By the way, in the case where the newspaper splicing paper and the commercial printing web are subjected to the pre-joining process, both require a dedicated tab T as shown in FIGS. 31 and 32. To do. However, since the tab T is relatively expensive (a high one costs about 100 yen) and is a consumable item, there is a problem that the processing cost is significantly increased. In particular, newspaper printing factories use hundreds of tabs T per day, so the processing cost will rise by several million yen or more per year.

Further, in the case where the paper splicing pretreatment is automated, when the tab T is attached to the front end portion of the paper roll P, it is disclosed in Japanese Patent Laid-Open No. 63-
The tab attachment device disclosed in Japanese Patent Publication No. 295354 or Japanese Utility Model Publication No. 5-11248 is additionally required, which causes a problem that the structure of the processing device itself becomes extremely complicated and the manufacturing cost rises. . In particular, commercial printing paper roll P
In this case, since a plurality of tabs T are pasted, it takes time to attach the tabs T in one tab attaching device, resulting in a decrease in work efficiency. It should be noted that a plurality of tab attaching devices may be arranged to attach the tabs T efficiently, but in this case, the device becomes more complicated and the cost rises, and a large installation space is required. Such problems will occur.

Further, various papers such as coated papers, art papers, high-quality papers, medium-quality papers, waste papers, etc. are used for the commercial printing web P, and the paper quality thereof is extremely diverse. For example commercial printing paper roll P, it weight per 1m ² 30g~13
The range is as wide as 0 g, and the paper quality inevitably differs greatly. Therefore, in the commercial printing web P, when the paper splicing pretreatment is performed using the tab T having a uniform paper quality and shape, the paper quality of the web P and the paper quality of the tab T may be different. In this case, there arises a problem that the paper splicing in the paper feeding section of the rotary press 100 cannot be performed satisfactorily and reliably. For example, when the quality of the paper P is poor and the quality of the tab T is good,
A new winding paper P is formed by adhering and connecting the end portion of the winding paper P in use and the starting end portion of a new winding paper P with a paper splicing adhesive layer b.
When the front end of the web P is torn off from the outer surface of the web P, the tab T may not be cut and the front end side of the web P may be cut, which makes it impossible to splice the web P in a good and reliable manner. was there. It should be noted that the tab T may be made to have a poor quality so that the tab T is reliably cut when the web P is spliced, but in this case, before the web P is mounted on the web support device 101 of the rotary press 100. Since the tab T may be cut, it is not preferable to reduce the paper quality of the tab T. In order to solve these problems, the number of tabs T to be used is increased or decreased depending on the paper quality of the paper P, or several types of tabs T having different paper qualities are prepared and the tab T to be used according to the paper quality of the paper P is used. However, the method of checking the paper quality of the paper roll P one by one to increase or decrease the number of tabs T, or preparing several kinds of tabs T and selecting the tab T from them is complicated. Other problems will occur, such as increasing cost and cost.

Furthermore, if the paper quality of the paper roll P and the paper quality of the tab T are different, the amounts of expansion and contraction of both of them due to changes over time will differ. As a result, after the tab T is attached, the paper roll P
If the tape is not used immediately, the leading end of the web P may become loose due to aging, and the rotary press 100
In some cases, the paper splicing in the paper feeding part of the paper could not be performed satisfactorily and reliably.

The present invention was devised in order to solve the above problems, and the purpose thereof is to eliminate the need for a dedicated tab and to greatly reduce the processing cost, and to improve the paper quality of the paper roll and the tab. Automatic paper splicing processing method and automatic paper splicing processing device for winding paper in a paper feeding section of a rotary press regardless of conditions and simplifying the structure of the device itself. To provide.

[0011]

In order to achieve the above object, an automatic paper splicing method for a paper roll according to the present invention comprises a paper roll supporting step of rotatably supporting a paper roll by a paper roll support device, and a surface layer of the paper roll. After removing the part, the leading edge of the paper roll is fed out onto the table, the paper roll is cut out into a predetermined shape to form the tip, and the adhesive backing layer is formed on the back of the tip. And a back side adhesive layer forming step, and a front side adhesive layer forming step of forming a paper splicing adhesive layer on the tip surface and closer to the winding paper body side than the sticking adhesive layer at the time of forming the tip portion or after forming the tip portion. And, at the time of or after the formation of the adhesive layer for paper splicing, separate the part to which the adhesive layer for adhering is adhered at the front end portion of the paper roll and between the adhesive layer for adhering adhesive and the adhesive layer for paper splicing. For cutting A tab forming step of forming eyes and integrally forming a separable tab on the leading end of the paper roll, and a tab attaching process of rewinding the paper roll and attaching the tab ends to the outer surface of the paper roll It is a thing.

Further, the automatic paper splicing processing device for a web according to the present invention includes a web support device for rotatably supporting the web.
A peeling device, which is arranged above the paper roll support device and turns over the surface layer of the paper roll supported by the paper roll support device, and a paper splice at the tip of the rolled paper roll, which is arranged near the peeling device. And a paper pre-treatment device for splicing paper, which is arranged at a position substantially the same height as the outer peripheral surface of the upper side of the paper roll, and is wound up from the paper roll. The table that supports the feeding portion of the paper is disposed above the table, and the feeding portion of the paper roll is cut to form a leading end portion of a predetermined shape, and a cutting notch is formed at the leading end portion for separation. Cutter mechanism with a cutter that integrally forms a tab, a folding mechanism that sucks and holds the leading edge of the paper roll and folds it back onto the table, and a double-sided adhesive tape on the back and front of the leading edge of the paper roll to form an adhesive layer. One in which was formed from the tape applying mechanism to be formed.

[0013]

The web (for newspaper printing or commercial printing) conveyed to the paper feeding section of the rotary press is rotatably supported by the web supporting device. When the paper roll is supported by the paper roll support device, the peeling device removes the wrap and the surface layer portion of the paper roll. When the wamp or the surface layer portion is removed, the leading end portion of the paper roll is fed out onto the table, and this feeding portion is cut by the cutter mechanism to cut and form the leading end portion of a predetermined shape. When the front end of a predetermined shape is formed on the paper roll, a tape sticking mechanism forms a sticking adhesive layer on the back surface of the front end. When the adhesive layer for sticking is formed on the back surface of the tip portion, the adhesive layer for paper splicing is formed on the surface of the tip portion by the tape attaching mechanism, and the cutting notch is formed on the tip portion by the cutter mechanism. As a result, a severable tab is integrally formed at the leading end of the paper roll. When the tab is formed, the front end is rewound and the end of the tab is attached to the outer surface of the web.

According to the present invention, a separable tab is integrally formed at the front end portion of the paper roll to be subjected to the pretreatment for paper splicing, and the tab is used to stop the front end portion of the paper roll on the outer surface of the web roll. Therefore, a dedicated tab is unnecessary. As a result, the processing cost can be significantly reduced. Of course, a tab attaching device or the like for attaching the tabs is not required, so that the structure of the device itself can be simplified and the manufacturing cost can be reduced. Furthermore, since the tabs and the paper quality of the web are the same, the tab is surely cut when the web of the web is spliced, so that the web splicing of the web of paper can be performed reliably and satisfactorily. Moreover, since the tabs and the paper rolls have the same paper quality, both of them have the same amount of expansion and contraction over time.
As a result, even if the paper roll is not used immediately after the tab is attached, it cannot be said that the leading end portion of the paper roll is loosened due to aging.

After the cylindrical core material Pa is matched with the support shaft 4 provided on the arm 3, the support shaft 4 is inserted into the core material Pa so that the paper core support device 1 is rotatably supported. Note that the roll paper P conveyed to the paper feed section has the end plates that cover both end surfaces of the roll paper P removed, and the end of the wamp P ′ has the roll paper P.
It has a shape that is bent to the end face side of. Further, the peeling device A and the table 26 are in the retracted positions, respectively.

When the paper roll P is supported by the paper roll support device 1, the arm 3 rotates to move the paper roll P to the processing position (the solid line position in FIG. 1) and the frame 5 moves from above to the solid line position in FIG. The peeling device A and the table 26 are moved downward to approach the web P, and the swing plate 6 is then swung downward to bring the foot roller 14 into contact with the outer peripheral surface of the wipe P ′.

When the foot roller 14 comes into contact with the outer peripheral surface of the one-pitch P ', the traveling plate 7 travels on the oscillating plate 6 in the width direction, and the leaf spring 21 and the cutter 9'approach the end face of the web P. It stops in this state (see FIG. 9). The approach to the end surface of the paper roll P is detected by the positioning sensor 25.

When the leaf spring 21 and the cutter 9'approach the end surface of the paper P, the support arm 19 moves the fluid pressure cylinder 2
0 swings upward. At this time, since the front end of the leaf spring 21 is close to the end face of the paper P, the end of the one-pitch P'is locked by the leaf spring 21 and is lifted upward so that the end of the paper P and the one-pitch P'end. A gap is formed between the parts. Further, the blade 22 located between the leaf springs 21 cuts a part of the end portion of the one-pitch P '(see FIGS. 10A and 10B).

In this state, the support arm 19 further swings upward, the regulating roller 24 contacts the lower surface of the swing plate 6 to regulate the rise of the support arm 19, and the cutter 9'opposes the gap. Stop at the position you want.

When the cutter 9'stops at the position facing the gap, the traveling plate 7 travels on the oscillating plate 6 along the width direction of the paper P. At this time, since the two blades of the cutter 9'are in contact with the one-pitch P'and the surface paper of the web P, one or a plurality of the one-ply paper of the one paper P'and the paper P is conveyed along with the traveling of the cutter 9 '. Will be cut along the line (see FIGS. 11A and 11B).

FIG. 12 shows the surface layer paper of the wand P'and the paper roll P.
When the paper is completely cut along the width direction as shown in FIG. 3, air is jetted from the air jet nozzle 23 to the cutting portion, the cut portion is turned up, and the paper roll P is rotated in the feeding direction by the paper roll support device 1. , The turned-up one-piece P ′ and the cut end of the surface paper of the web P are the table 2
6 is extended (see FIGS. 13 and 14).

Since the foot roller 14 presses the wipe P'at the time of ejecting air, the flipped-up wipe P'and the surface paper of the paper P are prevented from sliding down, and the wipe P'and the paper P are prevented. The surface paper of this is Table 26
It is surely sent up. In this manner, the cutting and peeling process of the one-pitch P ′ of the paper roll P supported by the paper roll support device 1 and the surface paper is performed.

When the wipe P'is fed out onto the table 26 and the discrimination sensor 53 detects the boundary between the wipe P'and the web P, the feeding of the web P is once stopped and the support member 31 is moved to the support P. Traveling in the width direction, and the cutter mechanism 27 cuts the boundary portion between the one-pitch P'and the web P along the width direction to separate the one-pitch P'from the web P side (see FIG. 15).

The separated ones P'are discharged from the table 26 and transferred to the damaged paper processing device C, wound up in a round by the damaged paper processing device C, and then crushed into a flat shape to form a damaged paper. It is collected in the collection cart 62.

When the wipe P'is discharged, the flaw detection sensor 54 detects the stain or damage on the web P, and the web P is unrolled onto the table 26. When the stain P or damage is eliminated, the web P is removed. Feeding is stopped (see FIG. 15).

When a clean portion of the paper roll P is delivered onto the table 26, the suction holder 29a vacuum-adsorbs the paper web P, and in this state, the cutter mechanism 50 runs along the delivery direction, so that the paper surface on the table 26 moves. Both ends are cut diagonally (see FIGS. 17A and 17B).

When both ends of the paper surface on the table 26 are obliquely cut, the supporting member 31 travels in the width direction of the paper P, and the tip end is cut by the cutter mechanism 27 along the width direction (see FIG. 18 ( See A) and (B)). As a result, a substantially trapezoidal tip portion is formed. The separated waste paper is discharged from the table 26, transferred to the waste paper processing device C, rolled up by the waste paper processing device C, and then crushed into a flat shape to recover the waste paper recovery cart. 62
Be recovered to.

When the trapezoidal tip portion is formed, the suction holder 29a is turned over to the inverted position with the lower surface of the tip portion sucked and held, and the tip portion is folded back on the table 26.
In this state, the support member 31 travels in the width direction of the web P,
The tape sticking mechanism 28 forms the sticking adhesive layer a on the back surface of the front end portion in the width direction (see FIGS. 19A and 19B).

When the adhesive layer a for sticking is formed on the back surface of the tip portion, the suction holder 29a returns from the reverse position to the suction position, and thereafter the support member 31 travels in the width direction of the paper roll, and the tape sticking mechanism 28 is used. An adhesive layer b for splicing paper is intermittently formed on the surface of the tip portion and closer to the main body of the paper P than the adhesive layer a for sticking, and a cutting mechanism c is provided on the tip side of the adhesive layer b for splicing by a cutter mechanism. Are intermittently formed (see FIGS. 20A and 20B). The adhesive layer b for paper splicing and the cut c are formed so as to face each other.

When the adhesive layer b for paper splicing and the notch c for cutting are formed, the guide rail 30 slightly moves in the longitudinal direction of the table 26, and then the support member 31 travels in the width direction of the paper roll and the cutter mechanism 27. By this, cutting cuts c are intermittently formed closer to the paper P main body side than the paper splicing adhesive layer b (see FIG. 21). The cutting cuts c and the previously formed cutting cuts c are formed in a zigzag pattern. Due to the cutting cut c, a separable tab T is integrally formed at the leading end of the paper roll.

When the tab T is formed, the paper roll support device 1
Thus, the paper roll P is rewound. At this time, air is ejected upward from the suction holder 29a, and the tab T is prevented from being attached to the table 26. Further, at the time of rewinding the roll of paper P, since the tip end side is rewound while being handled by the brush 52, the end of the tab T is attached to the adhesive layer a.
It is affixed to the outer surface of the paper roll P via (see FIG. 22). In this way, the pre-treatment for splicing the commercial printing web P is performed.

The operations of the paper roll supporting device 1, the peeling device A, the pre-processing device B for splicing paper, and the waste paper processing device C are automatically controlled according to preset signals from a control device (not shown) such as a computer. Has been done.

Thus, the web P having been subjected to the paper splicing pretreatment is rotated at a speed equal to the paper feed speed of the web P supplied to the rotary press, and the end portion of the web P in use is newly replaced. When the start end of the paper P is pressed, both papers are attached and connected by the adhesive layer b for paper splicing, and the tab T is cut at the cut c portion as shown in FIG. As a result, the starting end of the new web P is continuously supplied to the rotary press.

Particularly, in the paper splicing pretreatment, a separable tab T is integrally formed at the tip of the web P to be subjected to the paper splicing pretreatment, and the tab T is used to form the tip of the web P. Since the paper is stopped on the outer surface of the web P, the tab T and the paper P have the same paper quality. As a result, the tab T is surely cut at the time of splicing the roll of paper P, and the splicing of the roll of paper P can be performed reliably and satisfactorily. Further, the dedicated tab T is not required, and the processing cost can be greatly reduced. Further, a device for sticking the tab T (for example, a tab sticking device or the like) is not required, and the structure of the device itself can be simplified and the manufacturing cost can be reduced. In addition, since the tab T and the paper roll P have the same paper quality, both of them have the same amount of expansion and contraction over time. As a result, even if the web P is not used immediately after the tab T is attached, the leading end of the web P does not become loose due to changes with time. In addition, in the automatic paper splicing processing device, at the upper position of the paper roll support device 1, the one-piece P'of the paper web P supported by the paper roll support device 1 is cut and peeled to expose the surface layer portion of the paper web P. Since the device A is provided, and the paper splicing pretreatment device B for performing the pretreatment for paper splicing is provided at the position near the web supporting device 1 at the tip of the rolled-up paper P. Further, it is possible to fully automate the one-piece removal processing of the paper roll P and the pretreatment for paper splicing, so that the working efficiency can be greatly improved and the labor cost can be reduced. However, since the peeling device A and the pretreatment device B for paper splicing are integrated, the device itself can be made compact, the structure can be simplified, and the cost can be reduced.

In the above embodiment, the automatic paper splicing processing device is installed in the paper feeding section of the rotary press, but the automatic paper splicing processing device is installed in the winding paper conveyance path from the paper stock to the rotary press. It may be installed on the way to perform one-pitch removal of the paper roll P and pretreatment for paper splicing. In this case, it is necessary to dispose a roll paper support device (for example, a support device disclosed in Japanese Patent Laid-Open No. 63-295354) that rotatably supports the roll paper P below the table 26.

In the above embodiment, the web P having the outer peripheral surface covered with the one-pitch P'is processed. However, the web P having the one-piece P'removed in advance is rotatably supported by the web-supporting device 1. You may make it support and perform the pretreatment for paper splicing in the paper splicing pretreatment apparatus B. In this case, the peeling device A
In this case, a structure in which the surface layer of the paper P is cut and the cut end can be pulled out onto the table 26 is used.

In the above embodiment, the one-pitch P'and the damaged paper (surface layer paper) of the paper roll P are separated on the table 26, and both are separately collected by the damaged paper processing device C. It is also possible to collect the waste paper P'and the damaged paper of the web P by the damaged paper processing device C without separating them.

In the above embodiment, the tip end portion of the web P and the cutting notch c are formed by one cutter mechanism 27. However, a plurality of cutter mechanisms 27 are provided to wind the web. The formation of the tip of P and the formation of the cut c may be performed by different cutter mechanisms 27.

In the above embodiment, the adhesive layer for paper splicing b
For forming and cutting splicing c on the tip side of the adhesive layer b for paper splicing
The cutting notation c is formed at a position closer to the main body of the paper roll P than the adhesive layer b for paper joining, and the adhesive layer b for paper joining and both cutting notches c are all formed. It may be performed separately or all at the same time. Note that two cutter mechanisms 27 are required when simultaneously forming both cutting cuts c.

In the above embodiment, the adhesive layer b for paper splicing
Although the cut c for cutting is formed intermittently, it may be formed continuously. Also, the number of adhesive layers b for paper splicing and the number of cuts c for cutting are not limited to those in the above-described embodiment, and the front end portion of the paper roll P can be reliably attached to the end portion of the paper roll P in use. Any number may be used as long as it can be worn and the tab T can be surely cut at the cutting cut c.

FIGS. 24 and 25 are a schematic side view and a schematic plan view of an automatic paper splicing processing device for processing a newspaper printing web P, which is a newspaper printing press. Installed on the paper feeding section of the paper, and the outer peripheral surface of the newspaper printing web P is covered with the web P to remove the web P'and the pre-treatment for paper splicing is applied to the front end of the web P. It is composed of a device 1, a peeling device A, a pre-processing device B for splicing paper, and a damaged paper processing device C.

As the roll paper support device 1, a roll paper support device for a newspaper printing press is used, which has the same structure as a conventionally known one. In FIG. 24, 2 is a reel shaft, 3 is a three-pronged arm, and 4 is a support shaft.

Further, in the peeling device A, the pre-processing device B for splicing paper, and the broke paper processing device C, the supporting structures of the cutter mechanism 27 and the tape adhering mechanism 28 of the pre-processing device B for splicing the frame 5 are changed. Except for the above, the structure is substantially the same as that of the above embodiment. That is, the longitudinal direction of the table 26 (see FIG.
Guide rail 3 movably supported in the left-right direction
No. 0, the turning rail 64 is horizontally movably mounted via the support shaft 65 and is movable in the width direction of the table 26 (vertical direction in FIG. 25), and the turning rail 64 is provided with the cutter mechanism 27 and the tape attaching mechanism. 28 is movably supported via a supporting member 31 and a lifting member 32.

When the newspaper printing web P is processed using the automatic paper splicing processing device, the web P is first rotatably supported by the web support device 1. next,
The peeling device A removes the hump P ′ and the surface layer portion of the paper roll P, and feeds the leading end of the paper roll P onto the table 26. When the front end of the paper P is fed to the table 26, the turning rail 64 is turned to the solid line position and the alternate long and short dash line position in FIG. 25, and in this state, the supporting member 31 is caused to travel along the turning rail 64. The cutter mechanism 27 cuts the feeding portion of the web P into a V-shape to form the leading end. After that, the tip end portion is folded back by the folding back mechanism 29, the turning rail 64 is turned along the width direction of the table 26, and in this state, the tape sticking mechanism 28 forms the sticking adhesive layer a on the back surface of the tip end portion. . When the sticking adhesive layer a is formed, the folded-back portion of the tip portion is returned to the original state, the turning rail 64 is turned, and the tape sticking mechanism 28 forms the paper joining adhesive layer b on the tip surface. At the same time, the cutter mechanism 27 forms the cutting cut c. As a result, the separable tab T is integrally formed at the V-shaped tip. Finally, the front end portion of the paper roll P is rewound and attached to the outer surface of the paper roll P by the tab T (see FIG. 26). In this way, the paper splicing pretreatment of the newspaper printing web P is performed.

FIGS. 27 and 28 are perspective views of the web P having the leading end portion of the newspaper printing web P subjected to the paper pre-treatment by using the automatic paper web processor, and FIG. A separable rectangular tab T is integrally formed at the tip portion, and FIG. 28 shows a position where the cutting notch c is changed.

[0067]

As described above, according to the present invention, a severable tab is integrally formed at the front end of the web for pre-bonding, and the front end of the web is attached to the outer surface by using the tab. I'm trying to stop. As a result, it is possible to significantly reduce the processing cost without requiring a relatively expensive dedicated tab as in the conventional case. However, unlike the conventional case, a tab attaching device is not required separately, and the structure of the processing device is simplified. In addition, since the quality of the tab and the quality of the paper of the web are always the same, the quality of the paper of the tab and the paper of the web are different from each other, so that the tab is not cut at the time of splicing the web, and the leading end side of the web is cut. Without saying
The tabs are surely cut for splicing the web. As a result, regardless of the paper quality of the web or the tab, it is possible to reliably and reliably splice the web in the paper feeding section of the rotary press. Further, when the tab T and the paper roll P have the same paper quality, the elongation and contraction amount of the two become the same due to a change with time, and even if the paper roll is not used immediately after the tab is attached, the leading end of the paper roll becomes loose due to a change with time. There is nothing to say.
