Abstract

PURPOSE:To accomplish paper ending with high efficiency at low cost and reliably by sticking the base end portion of a tab to the leading end of the back of a V-shaped starting end portion with a squeeze plate. CONSTITUTION:First a table 6 is set at a designated position, and then the outer surface layer of wound paper is cut and removed by co-operation of a sucker with a main processor and so on. Further, an ending adhesive layer 11i and a cut having a pointed end portion are formed at the leading end portion of rolled paper by the main processor 3. Subsequently, paper is cut off along the cut, and the pointed end portion of the cut is folded back to the main body of the rolled paper by co-operation of the sucker with a squeeze plate 5. Further, the base end portion of the tab is sticked and fixed to the upper surface of the folded-back piece 7c by the main processor, and the rolled paper 7 is squeezed by the squeeze plate 5 and unwound. Lastly, the leading end portion of the tab is sticked and fixed to the outer surface of the drum portion of the rolled paper 7. Accordingly, there is only the adhesive layer 11i on the upper surface side of the V-shaped leading end portion, and there is no concave- convex portion due to the base end portion of the tab and the adhesive tape, so that there is no bad adhesion at the time of ending.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Applications) The present invention relates to improvements in a pre-processing device and processing method for automatic splicing of web paper, and is used as an accessory to a rotary press.

(Prior art) Generally, in a rotary press, a rotary press A is used as shown in FIG.
Using a pressing device F, the terminal end Ca of the web C, which is supported by the support trident B, is glued and spliced to the starting end Ea of the web E, which is rotated at a constant circumferential speed by a rotary drive device. Thus, paper is continuously fed to the rotary press A.

Therefore, in order to perform the automatic splicing of the web, the starting end Ea of the web E needs to be pretreated for adhesion.
Until now, all of the preprocessing has been performed manually. That is, the outer surface layer (4
~5 sheets) with a bamboo spatula, etc., cut the starting end Ea into a roughly V-shape as shown in Figure 14, and adhere the tip of the 7-shape to the web E side with a tab G.
A plurality of double-sided adhesive tapes H are attached to the outer surface of the starting end of the character.

However, some wholesalers say that the above-mentioned manual pre-processing for paper splicing is inefficient and leads to a rise in labor costs, and that the inner paper is likely to be damaged when the outer surface layer of the web E is peeled off.

Therefore, the applicant of this patent has developed an automatic paper splicing pre-processing device for the purpose of solving the various problems in the manual paper splicing pre-processing, and has published Japanese Patent Application No. 59-11176 and
This is published as No.-132651. That is, as shown in FIG. 15, the automatic paper splicing pre-processing device presses and holds the web starting end Ea with the squeezing roller (2), and (2)
A tab G is placed on top of the character-shaped starting end Ea, and both ends of the tab G are adhered to the starting end Ea and the roll body using adhesive tape H, respectively.

However, in the pretreatment device, the ladder roller I
, it becomes impossible to expose the upper adhesive layer of the double-sided paper splicing tape H that is attached to the upper surface of the starting end of the web E when it is attached to the starting end. As a result, after the attachment of the tab G is completed, it is necessary to individually peel off the upper surface protective paper of the double-sided tape H for paper splicing, and a lot of work is required to peel off the protective paper.

In addition, since the base end of the tab G is stuck above the V-shaped starting end Ea via the adhesive tape H', unevenness will occur on the upper surface of the ■-shaped starting end Ea. As a result, when press-bonding the terminal end Ca of the web C to the upper surface of the V-shaped starting end Ea, it is difficult to completely and tightly adhere the two, and there is a problem in that poor adhesion is likely to occur.

(Points to be Solved by the Invention) The present invention solves the above-mentioned problems in the pretreatment for paper splicing as disclosed in the above-mentioned Japanese Patent Application No. 59-11176. In order to do this, a protective paper is required on the top surface of the adhesive tape H for paper splicing, and it takes time to peel off the protective paper after attaching the tab G.
Since it is fixed to the upper surface of the V-shaped starting end Ea, unevenness is formed on the upper surface of the V-shaped starting end Ea, which tends to cause poor adhesion during paper splicing. A paper splicing pre-processing device and pre-processing device that enables highly efficient, low-cost, and reliable automatic paper splicing by attaching the paper to the tip of the back side of the V-shaped starting end Ea using an ironing plate. The present invention provides a processing method.

In addition, the second invention of the present application removes the surface layer of a rotatably supported web, and also feeds out the starting end of the web onto a table, and forms a paper splicing adhesive layer and cuts on the starting end using a main processor. After that, the starting end of the web is separated along the cut line,
Invention of folding back the cut end of the web using a sucker and attaching the base end of the tab tape to the upper surface of the folded piece, and then applying the tip of the tab tape to the outer surface of the web while squeezing the starting end of the web using a squeezing device. This is the basic configuration.

(Function) Cutting and removal of the outer surface layer is performed by the cooperation of the sucker 4 and the main processor 3, etc. Furthermore, the main processor 3 applies an adhesive layer for paper splicing to the starting end of the web fed onto the table 6. Then, a cut is formed to grow the tip.

In addition, the upper surface protective paper of the double-sided adhesive tape 11
The film was sequentially peeled off for 1 h.

The operation of applying the double-sided tape 11i as described above is continuously and repeatedly performed while moving the main processor 3 in any direction along the upper surface of the starting end of the web, thereby attaching the double-sided tape 11i to a desired position on the starting end of the web. An adhesive layer is formed. Incidentally, if it is necessary to leave the protective paper on the upper surface of the double-sided adhesive tape 11i attached, the peeler 11h is set in a non-operating state. Furthermore, although the adhesive layer is formed using double-sided adhesive tape in this embodiment, it is also possible to form the adhesive layer by applying an adhesive or the like.

As will be described later, the cutter device 12 cuts the starting end of the web cut by the horizontal blade cutter device 13 into a shape having a pointed end 7b such as a V-shape, and is lowered by the operation of the solenoid 12a to cut the paper into the paper surface. By moving the main processor 3 in a V-shape, a 7-shaped tip is cut and formed.

Of course, the rocking device 14 may have any other configuration, and a hydraulic piston or the like may also be used.

Next, the operation of the automatic paper splicing pretreatment device according to the present invention and the pretreatment method thereof will be explained.

First, as shown in FIG. 1, the web 7 is rotatably supported from both sides by the rotating shaft 2c of the web support device 2, and the height of the table 6 is made approximately parallel to the top of the web 7.

Next, as shown in FIG. 8, the sucker 4 is operated to suck the outer surface layer of the web 7 upward by the suction cup 4a. The outer surface layer of the web is generally loosened during transportation, and the suction cup 4
Although the paper is pulled upward by a few degrees by the vacuum suction in step a, the amount of the paper being pulled up is increased by rotating the paper roll 7 and squeezing the central part of the paper roll in the tightening direction by the squeezing device 5.

When suction by the sucker 4 is completed, the horizontal blade cutter 13 of the main processor 3 is activated to cut the surface layer of the web 7 in the width direction.

In FIG. 8, the horizontal blade cutter 13 is inserted from above the surface layer 7 of the paper web that has been pulled upward by the suction cup 4a, and the surface layer 7 is cut in the horizontal direction by moving the horizontal blade cutter 13 laterally. However, the suction cup 4a pulls up the surface layer at the end of the web 7, and the horizontal blade cutter 13 is inserted from the side to the back side of the pulled-up surface layer, and the cutter 13 is inserted into the surface layer. The surface layer portion 7 may be cut in the lateral direction by moving it laterally while in contact with the back side of the holder. Next, the web 7 is rotated to feed out the turn-up paper (surface layer paper) and the starting end 7a of the web onto the table 6, and the tip of the main processor 3 is swung upward, and the paper feeding device 9 The turned paper is discharged to the outside of the table 6 by the driven roller 9b, and the starting end 7a of the web is sandwiched between the roller 9b and the table surface.

Subsequently, the main processing device 3 is operated, and its adhesive layer forming device 11 is activated to sequentially apply double-sided adhesive tapes 11i for paper splicing to predetermined positions on the upper surface of the starting end of the web, as shown in FIG. , the cutter device 12 is operated to form a substantially V-shaped cut 15 having a pointed end 7b.

Note that it is preferable that the cut is not a complete cut, but leaves a small connecting portion at both ends.

Further, in this embodiment, the cuts 15 are formed after the adhesive tape 11i is pasted, but the cuts 15 may be formed first and then the adhesive tape 15 is pasted. Furthermore, when applying the adhesive tape 15, a necessary interval (L) is provided for the acceleration belt of the web 7 to come into contact with the adhesive tape 15, and the free pressing roller 11 of the adhesive layer forming device 11 is
Needless to say, the tape application position is determined and the adhesive layer forming device 11 is operated so that the adhesive tape does not touch the upper adhesive surface of the adhesive tape.

As shown in Figure 9, pasting of double-sided adhesive tape 11i and cut 15
When the formation of the roll is completed, the front end of the main processor 3 is swung upward and the paper feeding device 9 is activated to separate the starting end of the web along the square cut 15.

After that, operate the suction cup 4a of soccer 4, and first
As shown in (3) in the figure, lift the tip of the V-shaped starting end, insert the insertion plate 5a of the squeezing device 5, and fold back the ■-shaped tip 7b. Next, as shown in FIG. 10(B), the presser plate 5b is inserted above the folded piece 7C, its tip is folded back forward, and the folded piece 7c is pressed and held.

Then, the main processor 3 is operated to operate the tab tape supply device, and as shown in FIG. The tab tape 10f is fixed to the folded piece 7c with the adhesive tape 11i. In this case, the top protective paper of the adhesive tape 11i is not peeled off, and the upper adhesive surface of the tape remains hidden.0 Once the base end of the tab tape 10f has been fixed, the insert plate 5a is attached to the winding paper. Rewind the paper roll 7 while pressing the starting end, squeeze the ■-shaped tip 7b, release the V-shaped tip 7b from the table 6, and then continue to operate the main processor 3 to create double-sided adhesive as shown in FIG. The tip of the tab tape 10f is fixed to the outer surface of the web 7 with the tape 11i. After fixing the tip of the tab tape 10f, the squeezing device 5 is removed, the main processor 3 is operated, and a double-sided adhesive tape is attached to the upper surface of the V-shaped tip 7b to form an adhesive layer. It is desirable to form. Also, squeezing device 5
The insertion plate 5a and the presser plate 5b may have relatively small outer dimensions (about 10-151M in width) that can effectively press the folded piece 7c.
Even if the upper surface protective paper of the adhesive tape 11i for paper splicing attached to the adhesive tape 11i is peeled off at the same time as it is attached, the ironing device will not touch the adhesive layer.

(Effects of the Invention) As described above, the present invention can automatically perform all the pre-treatments for paper splicing at the starting end of the web, which greatly improves work efficiency. There will be no damage at all.

Further, in the present invention, the squeezing device 5 is formed by the narrow insertion plate 5a and the two-handed presser plate 5b, and the squeezing device 5 is
The tip of the V-shaped starting end of the web is folded back and the base end of the tab is pasted on the back side of the tip by the cooperation of the sucker 4 and the V-shaped starting end, so that the top side of the V-shaped starting end is used for paper splicing. Since only the adhesive layer 11j exists and there are no irregularities caused by the tab base end or the adhesive tape for attaching the tabs, there is no adhesion failure during paper splicing, and extremely reliable automatic paper splicing can be performed.

Furthermore, since the ironing device 5 having the above-mentioned configuration is used, even if the protective paper on the top surface of the double-sided adhesive tape pasted on the top surface of the ■-shaped end is continuously peeled off at the same time as the tape is pasted, the tab will not stick. Sometimes the squeezing device 5 does not come into contact with the adhesive layer.

As a result, the conventional manual work of peeling off the protective paper on the top surface of the double-sided adhesive tape for paper splicing becomes unnecessary, and it is possible to significantly reduce processing costs and completely automate the pre-processing for paper splicing.

As mentioned above, the present invention has excellent practical utility.
