Therefore, in order to perform the automatic adhesive splicing as described above, it is necessary to pre-process the starting end Ea of the web for gluing, but up until now, all of the pre-treatment for adhesive splicing has been performed manually. It's been coming. That is, first, the outer surface layer (3 to 5
Peel off the sheet) with a bamboo spatula, etc., and then
Ea is cut into a substantially V-shape as shown in FIG. 9, and its tip is attached to the outer surface of the body of the web E using a tab G. Next, a plurality of double-sided adhesive tapes H are attached to the outer surface of the starting end of the V-shaped web, and the upper protective paper is peeled off to expose the adhesive layer.

However, manual pretreatment for adhesive splicing has a problem in that work efficiency is low, leading to a rise in labor costs, and it is difficult to accurately and quickly apply the adhesive tape to a predetermined position on the starting end Ea of the web. Furthermore, the starting end of the paper roll is often damaged when applying or cutting the adhesive tape, which poses a problem in that adhesion errors are likely to occur.

On the other hand, in the field of packaging equipment, adhesive tape applicators have been developed for various types of automatic packaging such as paper packages. However, each tape applicator has a complicated structure, making it difficult to reduce manufacturing costs, and it also requires too much time and effort to operate and repair.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems in automatic packaging equipment and automatic adhesive splicing pre-treatment of paper rolls, namely, the structure of the adhesive tape applicator is complicated and it is difficult to reduce manufacturing costs. (b) Work efficiency is low and it is difficult to apply the adhesive tape to a predetermined position accurately and quickly; (c) The starting end of the paper roll is easily damaged when applying the adhesive tape, and adhesion errors are likely to occur. This technology aims to solve problems such as the following: adhesive tape can be applied to a desired shape with high efficiency and accuracy to a predetermined position on the surface of the material to be bonded, without damaging or staining the surface of the material to be bonded. The present invention provides an automatic adhesive tape applicator as described above.

(Means for Solving the Problems) The present invention includes a case body 8 movably disposed on the base frame 2a; A roll-up adhesive tape 16; a roller 18 along which the roll-up adhesive tape 16 is fed out along its outer surface; and a drive device 2.
2, the needle-shaped body 21b protruding from the tip of the arm 21a is pierced onto the roll-up adhesive tape 16 on the roller 18, and the rotation of the arm 21a causes the tip of the roll-up adhesive tape 16 an adhesive tape holding member 21 that pulls out the wound adhesive tape 16 onto the surface of the material to be bonded; disposed so as to be able to move toward and away from the surface of the material to be bonded; A presser device 20 for pasting the wound adhesive tape 16 with the needle-like body 21b of the adhesive tape holding member 21 pierced and the tip end stuck onto the surface of the material to be adhered to the needle-like body 21b. A cutter 19 that cuts from the tip end side of the piercing point; From the tip end of the wound adhesive tape 16 stuck onto the surface of the material to be adhered by the presser device 20;

(Function) The holding device 20 of the adhesive tape applicator is supported so as to be able to move toward and away from the surface of the material to be adhered, and moves at a constant speed in a predetermined direction along the surface of the material to be adhered. First, as the adhesive tape holding member 21 holding the adhesive tape 16 rotates, the adhesive tape is delivered onto the material to be adhered through the lower side of the presser device 20 that has been pulled upward. When the feeding of the starting end of the tape is completed, the presser device 20 is lowered onto the material to be adhered, and the end of the tape is adhered onto the surface of the material to be adhered. Once the end of the tape is pasted, the adhesive tape is continuously fed out by moving the tape pasting device and is successively pasted onto the material to be adhered.

The adhesive holding member 21 separates from the adhesive tape when it passes under the presser device 20, rotates to the latter position, and then stops there. When pasting of a predetermined length of adhesive tape is completed and the time to cut the tape approaches, the adhesive material holding member 21 starts rotating again and reaches above the roller 18, where it engages with the adhesive tape again. hold this.

When the adhesive material holding member 21 holds the adhesive tape, the cutter 19 is operated to cut the tape. The end portion of the cut tape is pressed onto the surface of the material to be adhered by the presser device 20 as the applicator moves, thereby completing the adhesion of the tape of a predetermined length.

The cutter 19 operates in the state where it is pierced, and the tape 16 is cut near the feeding side of the needle-shaped body 21b.

Next, the operation of the adhesive tape applicator 11 according to the present invention will be explained.

When forming an adhesive layer for adhesion and splicing on the starting end 7a of the paper web pulled out onto the table 6, first, the main processing device 3 is positioned on the table 6, and the main processing device 3
While aligning the holding position with the direction in which the adhesive layer is formed, the swinging device 13 is operated to lower the front end of the main processing device 3 and place the presser roller 20 in a position where it can be freely bonded to the upper surface of the starting end of the web.

Next, the rotation drive device 2 of the adhesive tape applicator 11
At the same time, the main processor 3 is moved along the table 6 in the adhesive layer forming direction. When the rotary drive device 22 rotates, the holding mechanism 20a of the presser roller 20 operates in synchronization with the rotation, and the presser roller 20 is lifted slightly above the plane of the paper and pierces the tip of the adhesive tape 16 on the drawer side. The tip of the adhesive tape 16 is pulled out by the needle-shaped body 21b via the guide roller 17, and is fed out through the lower side of the presser roller 20 onto the starting end of the web.

When the tip of the tape comes into contact with the needle remover 23, the needle-like body 21b comes off from the adhesive tape 16, and the needle-like body 21b that has been pulled off from the adhesive tape 16 continues to rotate and is attached to the tread surface of the grooved roller 18. At this point, the adhesive tape 16 is stuck again.

On the other hand, the tip of the adhesive tape 16 is connected to the presser roller 20.
When the tape is fed out downwardly, the presser roller 20 descends and presses the starting end 7a of the paper roll, and the adhesive layer formed on the lower surface of the adhesive tape sticks to the paper surface. Once the tip of the adhesive tape 16 is attached, the adhesive tape 16 continues to be fed out via the presser roller 20 even after the needle-shaped body 21b is removed from the adhesive tape 16 due to the subsequent movement of the main processor 3. and is adhered onto the starting end 7a.

The needle-shaped body 21b is moved again to the grooved roller 1 as described above.
When the tape 16c is pierced in step 8, the cutter 19 is activated to cut the tape 16c, and the main processor 3 continues to move, so that the cutter 16c is completely pasted. It will be worn.

By repeating the above operations, a predetermined length of double-sided adhesive tape 16 is adhered onto the starting end 7a of the web as shown in FIG. The length L of the adhesive tape depends on the moving speed of the main processor 3 and the rotating needle 21.
The adhesive tape 16 of any length can be attached by appropriately adjusting the relationship between the two speeds.

In addition, in the case of newspaper rolls, etc., a width L' is provided on the starting end 7a of the roll of paper, in which multiple strips of adhesive tape 16 are usually cut into a V-shape, so that the belt of the rotary drive device comes into contact with it during adhesive splicing. They are glued one after another.

Further, although the explanation is omitted in this embodiment, if necessary, a peeler for the surface protection paper of the double-sided adhesive tape 16 is installed downstream of the needle remover 23, and the peeler removes the adhesive. double-sided adhesive tape 16
Of course, the surface protection paper may be continuously peeled off to expose the adhesive layer.

Although each embodiment of the present invention has been described above,
In each of the embodiments described above, the pressing device 20 for the adhesive tape 16 is a pressing roller supported movably in the vertical direction. However, as the presser device 20, in addition to this, a belt may be wound around a plurality of pulleys.
It is possible to use a belt with a structure in which the tape 16 is pressed by the belt (not shown) or a belt with a semicircular outer peripheral curved surface and with a structure in which the tape 16 is pressed while sliding on the curved surface (not shown). be.

Further, in place of the rotary support needle 37, it is free to use a suction cup body (not shown) having a suction means at the upstream portion as the adhesive tape holding member 21, and furthermore, the grooved roller 18 For example, fill the groove with a soft material such as urethane rubber (not shown), or replace the grooved roller 18 with a non-grooved soft roller, or use two discs of appropriate thickness spaced apart. They may be arranged in parallel (both not shown). Moreover, by knurling the circumferential surface of the grooved roller 18 or a roller replacing the grooved roller 18, the double-sided adhesive tape 16
It is effective to prevent the double-sided adhesive tape 16 from adhering to the roller circumferential surface more than necessary by appropriately reducing the contact area with the roller. Incidentally, when the suction cup body is used instead of the rotary support needle 21, the groove of the grooved roller 18 is not necessary, and it is of course unnecessary to provide the needle remover 23.

In the above embodiments, a so-called double-sided adhesive tape is used to form the adhesive layer, but any type of adhesive tape may be used as long as it has an adhesive layer formed on the bottom side. Moreover, the object to which the tape is attached is not limited to newspaper rolls, and it goes without saying that the present invention can be applied to any sheet-like material to be adhered.

(Effect of the invention) In the present invention, the adhesive tape holding member 21
is engaged with the adhesive tape 16 and pulled out, and the tape 16 is cut while the adhesive tape holding member 21 is engaged with the adhesive tape 16 on the roller 18, so that the tape 16 is cut. The starting end of the tape can be reliably held during pulling out and cutting, and the adhesive tape can be applied quickly and smoothly. Furthermore, after the end of the tape is pulled out, by moving the applicator main body, the tape 16 is continuously pulled out and pasted via the presser device 20, so the applicator main body can be moved at high speed. Adhesive tape can be applied reliably even when the adhesive tape is used, and the efficiency of packaging operations can be greatly improved.

Furthermore, the present invention is constructed from an extremely simple mechanism, which reduces manufacturing costs, and allows for easy adjustment of the length of the adhesive tape piece 24, providing excellent practical utility.
