[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in an automatic paper splicing pretreatment device for a paper roll for preprinting a newspaper printing paper roll, and has a substantially V-shaped tip surface of the paper roll. The present invention relates to a front end processing device for a roll of paper, in which a double-sided adhesive tape is attached to form a pressure-sensitive adhesive layer for paper splicing, and a T-shaped tab is attached to the rear surface of the front end.

[0002]

2. Description of the Related Art Generally, newspaper printing webs carried into a paper feed unit of a printing press are preliminarily spliced so that automatic paper splicing can be performed at the paper feed unit of the rotary press. Pre-processed. In this paper splicing pretreatment, as shown in FIG. 22, the leading end portion of the paper roll P is cut into a substantially V shape,
A double-sided adhesive tape is adhered to the front surface of the front end to form a paper splicing adhesive layer a, and the front end is wound with a tab T to wind up the paper P.
It is attached to the outer surface of.

In recent years, most of the paper splicing pretreatment for newspaper printing rolls has been automated in order to reduce labor costs and improve work efficiency. For example, Japanese Patent Laid-Open No. 63-295354 and Japanese Unexamined Utility Model Publication No. 63-295354. This is performed using the automatic paper splicing pretreatment device disclosed in Japanese Patent Laid-Open No. 62-38268. That is, the automatic paper splicing pretreatment device cuts the table on which the leading end of the paper roll is placed and the leading end of the paper roll into a substantially V shape, and attaches a double-sided adhesive tape to the surface of the leading end to splice paper. It is equipped with a main processor that forms an adhesive layer for paper, and a tab sticking device that sticks the base end of the tab to the approximately V-shaped tip of the paper roll. Each processing step such as cutting processing of the leading end portion, forming a paper splicing adhesive layer on the leading end portion of the paper roll, and adhering a tab to the leading end of the paper roll can be sequentially and automatically performed. Also, as shown in FIG.
As shown in (A) and (B), T-shaped tabs T and substantially rectangular tabs T are used, and these are all core papers T.
Adhesive layers Tb are provided on the front and back surfaces of a, and protective paper T'is attached to the front and back surfaces thereof.

Thus, in the rotary printing press, as shown in FIG.
As shown in, a new paper roll P that has been pretreated for paper splicing
Is attached to the three-pronged arm 100, and is rotated at a constant circumferential speed with the web P'in use that is being fed to the rotary press 101 at a constant speed. When the pressing device 102 presses the starting end portion of the new paper roll P, the terminal end part of the paper roll P ′ in use and the starting end part of the new paper roll P are attached and connected by the adhesive layer a for paper splicing, and the tab T is formed. New paper roll P that has been cut
The starting end portion of is continuously supplied to the rotary press 101.

[0005]

By the way, the tab attaching device used in the above-mentioned automatic paper joining pretreatment device is such that when the tab is attached to the substantially V-shaped tip of the paper roll, a protective paper or scraper is used. After peeling with a roller, the tab is attached to the front end of the paper roll. That is, the tab is sucked and held by a vacuum suction board, and in this state, a scraper is inserted into the back surface of the protection paper of the tab to peel off the protection paper, or a roller rotating at a low speed is brought into contact with the protection paper surface to protect the tab. The paper is peeled off by scraping it, and then the vacuum suction disk is moved to the front end side of the winding paper to attach the tab to the substantially V-shaped front end of the winding paper. However, in a tab sticking device in which the protective paper is peeled off with a scraper or roller, it is extremely difficult to peel off the protective paper reliably and smoothly because the adhesive layer of the tab and the protective paper are in close contact with each other. However, there is a problem in that the tab may be stuck incorrectly and the tab itself may be easily damaged.
In addition, the tab attaching device using the rectangular tab is considerably expensive (the expensive one costs about 100 yen) as compared with the T-shaped tab, and is a consumable product. There was a problem that it would cause a sharp rise in costs. In particular,
In newspaper printing factories, hundreds of tabs are used per day, so the processing cost will rise by several million yen or more per year. Further, when the paper roll is subjected to the paper splicing pretreatment by using the T-shaped tab, the paper splice adhesive layer is not formed on the substantially V-shaped tip surface (the surface of the apex portion) of the paper roll. Therefore, when the paper is spliced in the paper feeding unit of the rotary press, the front end of the web is not stuck and connected to the end of the running web, and the tab may not be cut. As a result, there has been a problem that the splicing cannot be performed reliably and satisfactorily in the paper feeding section of the rotary press.

The present invention was devised to solve the above-mentioned problems, and its purpose is to use a relatively inexpensive T-shaped tab from which the protective paper can be reliably and easily peeled off. Prevent tabs from sticking mistakes and tab damage,
An object of the present invention is to provide a leading edge processing device for a rolled paper, which is capable of reliably and satisfactorily splicing a paper in a paper feeding section of a rotary press.

[0007]

In order to achieve the above object, a device for treating a front end portion of a paper roll according to the present invention comprises a tape supply device for supplying a double-sided adhesive tape having a fixed length and having a protective paper on the front surface side, The tape supply device further comprises a tab attaching device that receives the double-sided adhesive tape and attaches the double-sided adhesive tape to the front surface of the substantially V-shaped tip of the paper roll, and attaches a T-shaped tab to the rear surface of the front end of the paper roll. The device is rotatably supported by a tape reel, and a reel-shaped double-sided adhesive tape in which protective paper is pasted on the surface side of the adhesive layer, and a tape pull-out mechanism that grips the tip of the double-sided adhesive tape and pulls out a certain length from the tape reel. And a cutter mechanism for cutting the pulled out double-sided adhesive tape to a predetermined length, and the tab attaching device is provided on both sides of the base end of the T-shaped core paper and the tip of the back face thereof. Adhesive layer Then, a tab mounting mechanism for supporting and mounting a tab in which front surface protective paper and back surface protective paper having the same shape are attached to the front and back surfaces of the core paper in a laminated manner, and a constant supplied from the tape supply device. A double-sided adhesive tape of length is adsorbed and held, and this is adhered to the substantially V-shaped tip surface of the paper roll, and the surface protective paper of the tab placed on the tab placing mechanism is adsorbed and one tab is attached. An upper tab holder that can be moved back and forth, left and right, and moved up and down, a drive mechanism for the upper tab holder that moves the upper tab holder back and forth, left and right, and up and down, and the back surface of the tab sucked and held by the upper tab holder. The protective paper is adsorbed and held to form a gap between the tab core paper and both protective papers, and the base end of the tab from which the surface protective paper has been peeled off is attached to the front and back of the roll paper, and the back surface is protected. Before peeling the paper and handing it over to the upper tab holder The lower tab holder that can be moved and moved up and down, the lower tab holder drive mechanism that moves the lower tab holder back and forth, and the up and down movement, and the surface that is inserted into the gap formed between the tab core paper and the surface protection paper. And a surface protective paper peeling mechanism provided with a wedge capable of advancing and retreating the protective paper from the core paper.

[0008]

[Function] The T mounted on the tab mounting device in a laminated manner
Only one letter-shaped tab is suction-held by the upper tab holder. At this time, the tab is in a state in which the surface protective paper side is adsorbed. When the upper tab holder adsorbs and holds the tab, the lower tab holder adsorbs the back surface protective paper of the tab, and in this state, the lower tab holder slightly lowers. As a result, a gap is formed between the core paper and both protective papers. When a gap is formed between the tab core paper and both protective papers, the wedge of the surface protective paper peeling mechanism is inserted into the gap between the core paper and the surface protective paper, and the surface protective paper is peeled from the core papers. It by this,
The upper tab holder adsorbs and holds the front protective paper, and the lower tab holder adsorbs and holds the core paper and the back protective paper. When the surface protective paper is peeled off from the tab, the surface protective paper is collected by the protective paper collecting mechanism. Then, the upper tab holder receives the double-sided adhesive tape of a constant length from the tape supply device, adheres the double-sided adhesive tape to the substantially V-shaped tip surface of the paper roll on the table, and sucks the tip to flip it upward. . When the front end to which the double-sided adhesive tape is attached is flipped up, the lower tab holder holding the tab from which the surface protective paper has been peeled goes under the front end of the paper roll, and the front tab is pressed downward by the upper tab holder. by this,
The base end portion of the tab is attached to the back surface of the front end of the paper roll. When the base end of the tab is attached to the back of the tip of the paper roll,
Move with the lower tab holder adsorbing the back side protective paper,
Peel backside protective paper from the tab. The peeled back surface protective paper is delivered to the upper tab holder and collected by the protective paper collecting mechanism.

Since the winding paper leading edge processing apparatus of the present invention uses the relatively inexpensive T-shaped tab to perform the leading edge processing of the winding paper, the processing cost can be greatly reduced. Further, the front end processing device adsorbs and holds the front and back surface protective paper of the tab by the upper tab holder and the lower tab holder respectively to form a gap between the core paper of the tab and the front and back protective paper, Insert a wedge to remove the surface protection paper,
Since the back side protective paper is peeled off by adsorbing and holding the back side protective paper by the lower tab holder and moving the lower tab holder, both sides of the tab protective paper can be surely and smoothly peeled off. As a result, neither tab sticking error nor damage to the tab itself will occur. Of course, the front end processing device has a substantially V-shaped front end surface (surface of the apex) of the paper roll.
Since the double-sided adhesive tape is adhered to the paper, the front end of the paper roll is reliably adhered to the trailing end of the running paper roll during splicing. As a result, the tabs are surely cut at the time of splicing the paper rolls, so that the splicing of the paper rolls can be performed reliably and satisfactorily.

When the surface protective paper T ′ is peeled off, the upper tab holder 28 horizontally moves from the tab holding position to the protective paper discarding / tape receiving position while holding the surface protective paper T ′, and from the standby position to the protective paper receiving position. The adsorption state of the surface protective paper T ′ is released directly above the moving protective paper recovery box 60, and the surface protective paper T ′ is thrown into the protective paper recovery box 60 (see FIG. 14). The protective paper storage box 60
Moves from the protective paper receiving position to the standby position after collecting the surface protective paper T '. When the upper tab holder 28 discards the surface protective paper T ′, the tape feeding device 7 moves from the tape retracting position to the tape feeding position, and the tape pull-out mechanism 13 pulls the tape t from the tape reel 19 for a certain length. In this state, the rear end holder 28b of the upper tab holder 28 at the protective paper dumping / tape receiving position swings to the tape suction position to suck the protective paper side of the tape t, and then the cutter mechanism 14 operates to perform double-sided adhesive. The tape t is cut (see FIG. 15). As a result, the double-sided adhesive tape t having a fixed length is adsorbed and held by the rear end holder 28b. The rear end holder 28b swings upward after adsorbing and holding the double-sided adhesive tape t.
Also, the tape supply device 7 returns to the tape retreat position after supplying the tape t of a fixed length. Upper tab holder 28
When the double-sided adhesive tape t is adsorbed and held, the upper tab holder 28 moves at a height of the tab holding position to just above the substantially V-shaped tip of the web P on the table 4, and then descends to the tape attaching position to wind the web. The double-sided adhesive tape t is attached to the front surface of P (see FIG. 16). At this time, the double-sided adhesive tape t is in a state in which protective paper is attached. When the double-sided adhesive tape t is attached to the front surface of the paper roll P, the upper tab holder 28
Moves up to the turning position with the front end of the paper roll adsorbed. As a result, the leading edge of the paper roll P is turned up (see FIG. 17). When the front end of the paper roll P is flipped up, the lower tab holder 30 holding the tab T in this state moves forward slightly above the table 4 and goes under the front end of the winded paper roll P. (See Figure 17). The lower tab holder 30 is a paper roll P.
When the lower tab holder 30 descends below the leading edge, the lower tab holder 30 descends to the tab attaching position, and the upper tab holder 28 descends from the flipping position to the pressing position to press the leading edge of the paper P to the lower tab holder 30 side. As a result, the base end portion of the tab T held by the lower tab holder 30 is attached to the back surface of the front end of the web P (see FIG. 18). When the tab T is attached to the back surface of the front end of the paper P, the upper tab holder 28 returns to the tab holding position, and the lower tab holder 30 rises slightly above the table 4 to adsorb the back surface protective paper T ″. Then, the back protective paper T ″ is peeled off from the core paper Ta (see FIG. 19). When the lower tab holder 30 peels off the back surface protective paper T ″, the lower tab holder 30 retracts slightly above the table 4 and stops immediately below the upper tab holder 28 at the tab holding position, and then the protective paper suction position. Then, the back side protective paper T ″ is raised to the upper tab holder 28 (see FIG. 20). The lower tab holder 30 returns to the standby position after delivering the back surface protective paper T ″ to the upper tab holder 28. The upper tab holder 28 receiving the back surface protective paper T ″.
Releases the suction state of the back side protective paper T ″ right above the protective paper collection box 60 which is horizontally moved from the tab holding position to the protective paper dumping / tape receiving position and is moved from the standby position to the protective paper receiving position. The rear protective paper T ″ is thrown into the protective paper collection box 60 (see FIG. 21). Then, the upper tab holder 28 returns to the tab holding position after discarding the back surface protection paper T ″, and the protection paper storage box collects the back surface protection paper T ″ and then returns from the protection paper receiving position to the standby position. Move to. In this way, the double-sided adhesive tape t is attached to the front surface of the substantially V-shaped tip of the paper roll P, the protective paper is peeled off from the tab T, the protective paper is discarded, and the tab T is adhered to the rear surface of the substantially V-shaped tip of the paper roll P. And so on.

The paper P that has been subjected to the pretreatment for splicing by the automatic pretreatment device for splicing is placed on the three-pronged arm of the paper feeding section of the rotary press with the protective paper of the double-sided adhesive tape t at the leading end peeled off. It is installed. Thus, the web P supported by the three-pronged arm is rotated at a speed equal to the paper feed speed of the web P supplied to the rotary press, and the end of the web P in use becomes the start end of the new web P. When pressed, both papers are attached and connected by the paper splicing adhesive layer and the double-sided adhesive tape t, and the tab T is cut at the cutting cut Tc portion. As a result, the starting end of the new web P is continuously supplied to the rotary press. In particular, the pretreatment for paper splicing is
Since the double-sided adhesive tape t is attached to the front end surface (the surface of the apex portion) of the paper roll P, the front end of the paper roll is surely attached to the end part of the paper roll in use at the time of paper splicing. As a result, the tab T is surely cut at the time of splicing the paper rolls, so that the splicing of the paper rolls can be performed reliably and satisfactorily.

[0033]

As described above, the paper edge processing device of the present invention uses the relatively inexpensive T-shaped tab to perform the edge processing of the paper, so that the processing cost is greatly reduced. Can be planned. Further, the front end processing device adsorbs and holds the front and back surface protective paper of the tab by the upper tab holder and the lower tab holder respectively to form a space between the core paper Ta of the tab and the front and back surface protective paper, and within the gap. A wedge is inserted to peel off the front surface protective paper, and the lower tab holder sucks and holds the rear surface protective paper and moves the lower tab holder to peel off the rear surface protective paper. Both protective paper can be peeled off reliably and smoothly. As a result, neither tab sticking error nor damage to the tab itself will occur.
Moreover, since the front end processing device attaches the double-sided adhesive tape to the front end surface of the web, the front end of the web is surely attached to the trailing end of the running web during splicing. As a result, the tabs are surely cut at the time of splicing the webs, and the webs of the webs can be spliced reliably and satisfactorily in the paper feeding section of the rotary press. In addition, since the front end processing device collects the peeled front and back protective paper by the protective paper collection mechanism, it can be said that the peeled protective paper is scattered and interferes with the pretreatment for splicing. Nor.
