Description

[Detailed Description of the Invention] (Industrial field of application) The present invention automatically uses a double-sided adhesive tape for the winding end of a paper roll formed by a web winding device of a paper mill and the surface of its inner paper layer. The present invention relates to a winding end tape applying device for a winding paper roll, which is provided with a paper scooping device for applying the tape to the paper.

(Prior Art) A web winding device (hereinafter referred to as a winder) that is generally used in a paper manufacturing plant, and a winding paper roll that is a cut portion of the paper when handling the roll in a post process. It is necessary to fix the winding end portion to the paper layer surface of the winding paper roll with a tape so that the end portion does not cause any trouble. The work for this is usually done manually, and particularly for thin paper rolls such as newspapers and high-quality paper, as shown in FIG. After pulling the portion 30 in the direction of the arrow 31 or folding the winding end portion into a triangle and pulling in the direction of the arrow 32 as shown in FIG.
Each tape 33 is attached as shown in (b).

However, since the work is a work that must be performed every time the winding by the winder is completed, the work frequency is high and the load on the operator is large, and further, the operator enters the web roll transfer path. Therefore, automation of tape application to the winding end of the roll of the paper roll is desired for reasons such as being unfavorable in terms of safety because it is a work of

In order to achieve this automation as easily as possible, a double-sided adhesive tape 32 is attached along the winding end to the paper layer surface inside the winding end 22 of the paper roll 1, as shown in FIG. A winding end process of attaching the winding end portion 22 and fixing the winding end portion can be considered.

(Problems to be solved by the invention) In the above-mentioned method for attaching the winding end tape using the double-sided adhesive tape, as long as the double-sided adhesive tape is simply attached to the surface of the paper roll, it is well known in the papermaking industry. This can be easily achieved by using a double-sided pressure-sensitive adhesive tape sticking device for a paper tube (for example, Japanese Patent Application No. 56-115624). In order to attach the double-sided adhesive tape to the layer surface, a technique of flipping the winding end portion and its vicinity before the tape is applied is indispensable, and this should be solved in advance in order to achieve the above-mentioned tape application method. At the same time, it is an issue that should be achieved by a simple, inexpensive and clean method.

(Means for Solving the Problems) For this reason, the present invention is directed to the winding end portion, which is a paper cutting portion, and the paper inside thereof so that the winding paper roll formed in the web winding device does not become loose in the subsequent process. In a device for attaching the layer surface to the surface via a double-sided adhesive tape, a wedge-shaped paper scoop that has a jetting port of an intermittently operated air jet at the tip and is movable in the tape attaching direction is opposed to the winding end. By arranging and moving in the width direction of the paper roll, a space is created between the end of the roll and the surface of the paper layer, and an adhesive tape is attached to the surface of the paper layer in the same space. The tape applying roller of the tape applying device is arranged at the rear portion of the paper scoop and is movable in the width direction of the paper roll integrally with the paper scoop, which is a means for solving the problem.

(Operation) The present invention holds the outermost layer of the outermost layer of the paper roll pressed by an arbitrary paper holder so that the outermost layer of the paper roll near the winding end does not shift relative to the inner paper layer. After that, the winding end is blown up by an air jet, a wedge-shaped paper scoop is inserted into this raised portion, and then the paper scoop is moved in the tape sticking direction with a tape sticking device.

If the direction, flow rate, and pressure of the air blown to the winding end are arbitrarily set according to the type of paper, it is easy to blow up the winding end from the paper roll, and this floating end A wedge-shaped paper scoop is inserted between the paper sheet and the paper layer on the inside of the sheet, and by advancing the paper scoop along the winding end together with tape application, the winding end can be easily picked up and at the same time double-sided adhesive. Attach the tape.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a winding end tape applying apparatus as an embodiment of the present invention, in which 1 is a roll of paper to be taped, 2 and 3 are roll end positions 4 of the same roll of paper 1. A pair of rotating rolls for rotating the paper roll 1 in order to position it at a position where tape can be applied, 5 are both sides using a paper tube tape applying device (Japanese Patent Application No. 56-115624) known in the paper manufacturing industry. Adhesive tape sticking device, 6 is a paper scoop having an air-jet jet nozzle according to the present invention, 7 is a mounting plate for the double-sided adhesive tape sticking device 5 and the paper scoop 6, and 8 is a mounting plate 7 for supporting the mounting plate 7 and moving it in the vertical direction. And a beam that allows the web roll 1 to be moved over the entire width 9. On the other hand, as shown in FIG. 1 and FIG. 2 which is a Z view of FIG. 1, the paper roll 1 has a paper pressing plate over its entire width.
It is designed to be held down by 10.

An embodiment of the paper scoop 6 which is a characteristic part of the present invention will now be described with reference to FIGS. 2 and 3. Reference numeral 11 denotes a paper scoop body which is formed in a wedge shape toward the tip and the winding end 22, 12 is a bracket for attaching the paper scoop body 11 to the mounting plate 7, 13 is an air nozzle for ejecting an air jet formed on the paper scoop body 11, 14 is an air flow rate adjuster, and 15 is an air pressure adjuster. Reference numeral 16 is an air tube, 17 is a thin plate for adjusting the blowing direction and blowing range of the air, and its mounting angle can be arbitrarily changed.

The tape applying method using the present tape applying apparatus will be described below. First, the direction of the arrow 18 shown in FIG.
As shown in FIG. 3, the paper scooping body 11 is the first roll when the tape is advancing, that is, the direction in which the tape is applied.
It stands by at a position before the side surface 20 of 19, and at the same time when the work starts, the air nozzle 21 is jetted from the air nozzle 13 of the paper scooping body 11 to blow up the winding end 22. By advancing the mounting plate 7 in this state, the paper scoop body 11 is inserted below the blown up winding end 22, and the air jet is temporarily stopped here. When the mounting plate 7 is further advanced and the winding end 22 is scooped up as shown in FIG. 2, the tape application roller 23 of the double-sided adhesive tape application device 5 which moves forward together reaches the first roll 19 from the time when the tape application roller 23 reaches the first roll 19.
