Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is mainly used in a pretreatment device for automatic adhesive splicing of paper rolls, etc., which is an auxiliary equipment of a rotary press or the like.

(Prior Art) Generally, in a rotary press A, as shown in FIG.
Continuous paper feeding is carried out by gluing and splicing ca to the starting end Ea of the web E, which is rotated at the same peripheral speed as this, by means of a pressing device F. In addition, in the figure, B is the trident for supporting the web, and D is
is a rotating drive device for the web.

Therefore, in order to perform automatic paper splicing as described above,
Although pretreatment for adhesion is required at the starting end Ea of the web, all of the pretreatment for adhesion has so far been performed manually. That is, 3 to 5 pieces of the outer surface of the web E supported by the supporting trident are peeled off with a bamboo spatula, etc.
Thereafter, the starting end of the web Ea is cut into a substantially V-shape as shown in Figure 7, and the tip is attached to the outer surface of the body of the web E using the tab G, and the V-shaped starting end of the web Ea is attached to the outer surface of the body of the web E. A plurality of double-sided adhesive tapes H are attached, and the upper protective paper is peeled off to expose the adhesive layer.

However, manual pretreatment for paper splicing has a problem in that work efficiency is low and labor costs are high, and the inside of the paper is easily damaged when the outer surface layer of the web is peeled off.

Therefore, the applicant of this patent has newly developed an automatic paper splicing pre-processing device for the purpose of automating the pre-processing of paper rolls for paper splicing, and has published this as Japanese Patent Application No. 132651/1983. That is, the main processor 2 which is the main part of the automatic paper splicing pre-processing device 1 of Japanese Patent Application No. 59-132651.
As shown in FIG. 8, it is composed of a case body 3, a paper feed device 4, a tab tape supply device 5, an adhesive tape applicator 6, a cutter device 7, a swing device 8 for the main processing device, etc. The case body 3 is disposed so as to be movable in the left-right direction on a guide rail (not shown) that is rotatably supported in a horizontal plane to a device (not shown), and the front end of the case body 3 is swingable in the vertical direction. .

The adhesive tape applicator 6 also includes a double-sided adhesive tape take-up reel 6a, a guide roller 6b, a grooved roller 6c, a cutter 6d, a free pressing roller 6e,
It is composed of a rotating needle 6f for holding and feeding out the tape, a needle removing needle 6g, etc.

A rotating needle 6f is pierced by a grooved roller 6c into the adhesive tape 6i fed out from the take-up reel 6a via a guide roller 6b.
The end of the adhesive tape is pulled out onto the starting end Ea of the web while being held by f. Further, when the adhesive tape is drawn out, the presser roller 6e is operated to press and stick the tip of the adhesive tape, and the movement of the main body 3 causes the adhesive tape 6i to be drawn out and stuck.

On the other hand, the rotating needle 6f is pulled off from the adhesive tape 6i by the needle removal 6g, and the stepping motor 6j
As the tape 6i is continued to be rotated by the grooved roller 6c, the tape 6i is again pierced by the grooved roller 6c. Katsuta 6
d operates with the rotating needle 6f piercing and holding the tape 6i, thereby cutting the tape 6i. After that, in the same way, pull out the tape tip, attach the tape tip, feed the tape and attach it.
The tape is held and cut.

Note that the top protective paper of the adhesive tape 6i that has been pasted is peeled off manually in a separate paper feeding section.

The pasting operation of the double-sided adhesive tape 6i as described above is as follows:
This is carried out continuously while moving the main processor 2 in any direction along the upper surface of the starting end Ea of the web, thereby forming a desired adhesive layer at a predetermined position on the starting end Ea of the web.

However, in the automatic paper splicing pretreatment device 1 according to Japanese Patent Application No. 132651/1980, it takes time to replenish the double-sided adhesive tape 6i that is consumed in the adhesive tape applicator 6, which is the main part, and the operating efficiency of the device is reduced. This has disadvantages in that, in addition to lowering the pressure, various troubles occur when replenishing the double-sided adhesive tape 6i.

(Problems to be solved by the invention) The present invention solves the above-mentioned problems in the main processor of the automatic paper splicing pre-processing device of Japanese Patent Application No. 59-132651, which was previously developed, namely (a) Replenishing the double-sided adhesive tape in the adhesive tape applicator takes time and makes continuous operation of the device difficult, and (b) it is often necessary to replenish the double-sided adhesive tape above the starting end of the web. , when replenishing the tape, the starting end of the web paper Ea
