Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a winding end tape for automatically attaching a tape to the winding end of a paper roll in a post process of a web winding device in a paper mill. The present invention relates to a pasting device.

(Prior Art) In a paper mill, a web roll formed by a web winder (hereinafter referred to as a winder) has a winding end portion at a right angle with respect to the end face of the paper roll when the roll rolls out of the winder. It is cut in the direction, but the winding end is fixed to the winding roll with tape so that this paper cut portion (hereinafter referred to as the winding end) does not interfere with the handling of the winding roll in the subsequent process. There is a need to.

An example of the method of applying the tape to the winding end portion will be roughly described on the basis of the technique disclosed in Japanese Patent Application No. 58-231874 already proposed. As shown in FIG. After receiving 1 on a roll rotating device composed of a pair of rotating rolls 16 and 17, the beam 3 which has been waiting at a high position in advance is lowered to the position shown in the drawing and installed over the entire width of the paper roll 1. While pressing the outermost layer of the paper roll 1 with the paper presser 18
The web roll 1 is rotated in the direction of arrow 19. At this time, when the position of the winding end 2 reaches the position 20 for tape application (in this example, the position of the winding paper roll 1 at 12:00), the rotation is stopped, and the tape guide 21 winds the one-sided adhesive tape 22. The tape is attached by a mechanism that moves the guide 21 over the entire width of the paper roll 1 while unwinding the adhesive tape 22 while pressing it against the paper roll 1.

Of the above, the role of the paper presser 18 is that the outermost layer of the web roll 1 is rotated when the web roll 1 is rotated by the frictional force generated between the paper presser 18 and the outermost layer of the web roll 1. The purpose is to prevent loosening or to positively remove the looseness, and also to prevent the winding end portion 2 from being pulled by the adhesive tape 22 and shifting in the width direction when the tape is attached.

In addition, as shown in FIG. 6, the winding end tape applying device for the thin paper winding paper roll such as newspapers and high-quality papers is used, as shown in FIG. When the and are adhered along the winding end portion 2 by using the double-sided adhesive tape 23, the paper presser 18 is attached with the arrow 19 in FIG.
It is also possible to use it as an ironing for pressing the winding end portion 2 against the double-sided adhesive tape 23 when the paper roll 1 is rotated in the same manner as the direction.

As described above, the paper presser 18 has an important role. On the other hand, on the other hand, the paper roll 1 that has been transferred from the winder.
Generally has several slits 24 in its width direction as shown in FIG. 7, that is, it is composed of several rolls.
Strictly speaking, each roll does not have a perfect circular shape with a perfect circle and the same diameter. The surface may be elliptical.

(Problems to be Solved by the Invention) As described above, when a plurality of paper rolls to be taped are coaxially arranged and each of them does not have a safe cylindrical shape with the same diameter, for example, As an extreme example, when the shape shown in FIG. 8 is formed, the surface 20 to be taped is not a flat surface having the same height, and the surface 20
Even if it is pressed by one paper retainer over the entire width of the paper roll 1 or by several paper retainers 18 as shown in FIG. It is impossible to press the outermost layer of the take-up roll uniformly, and therefore (1) the paper is loosened because the presser is not enough.

(2) Originally loose paper cannot be stretched even when the paper roll 1 is rotated.

(3) The part where the presser foot is not enough is pulled by the tape when it is attached and is displaced in the width direction.

(4) Especially, since the part 25 of the paper roll 1 shown in FIG. 9 is not pressed at all, there is a possibility that the outermost layer of the part 25 may slide down in the direction perpendicular to the same figure before tape is applied. .

Such problems occur.

The present invention is intended to solve these problems,
It is an object of the present invention to provide a winding end tape applying apparatus provided with a paper pressing device that always presses the entire width of a winding paper roll of any shape.

(Means for Solving the Problems) For this reason, the present invention relates to a device for affixing the winding end of a paper roll formed by a web winding device to the surface of the paper roll with a tape. A paper pressing device including a paper pressing plate divided into several parts in the width direction of the roll, a large number of through holes formed in the pressing plate in the paper width direction, and a large number of paper pressing weights inserted in the respective through holes. Is provided, which is a means for solving the above problems.

(Function) The paper pressing device applied to the present invention is such that a paper pressing plate divided into several pieces in the paper width direction is provided with holes subdivided in the width direction, and the paper pressing device is movable vertically in the holes. By inserting the weights, the subdivided paper pressing weights press the winding paper rolls at even intervals in the width direction in a substantially uniform state, and achieve the overhang and retention of the outermost layer of the winding paper rolls. Further, by appropriately selecting the weight of the paper presser weight or the material (friction coefficient) of the presser surface, it is possible to optimize the state of the paper presser.

(Embodiment) An embodiment of a paper pressing plate having a subdivided paper pressing weight, which is a feature of the present invention, will be described with reference to FIG. 1 and FIG. 2 which is a ZZ cross section of FIG. Roll of paper, 2
Is a winding end portion, 3 is a beam movable in the up-down direction 4 as shown in FIG. 5 and described above, 5 is a paper pressing plate mounted rotatably around a lower fulcrum 6 of the beam 3, The movable rotation range of the paper pressing plate 5 is limited to an arbitrary range 8 by the contact between the stopper 7 and the beam 3. Further, 9 is a paper presser weight, which is a characteristic part of this embodiment, and is inserted into a large number of holes 11 formed in the paper presser plate 5 over the width direction 10 of the paper roll 1, It is movable in direction 4. However, the lower limit of the paper presser weight 9 is limited by the contact between the upper end flange portion 12 of the paper presser weight 9 and the paper presser plate 5.

Next, the operation of the paper presser weight according to the present embodiment will be described.
Explaining with reference to the drawing, even in the paper roll 1 whose tape-bonding surface does not have a uniform height as shown in the figure, the paper pressing weight 9 subdivided causes the surface of the paper roll 1 to be equalized by its own weight. By pressing at a plurality of places at the interval 13, the paper can be pressed sufficiently and can be uniformly performed in the width direction.

Further, as shown in FIG. 4, the material of the contact portion 14 of the paper presser weight with the take-up paper roll 1 is made variable so as to change the material suitable for the paper type, that is, the friction coefficient, or It is also one of the features of the present invention that various means for optimizing the paper pressing state such as attaching another weight 15 on the pressing weight 9 and changing the weight thereof can be adopted.

(Effects of the Invention) As described above in detail, according to the winding end tape applying apparatus equipped with the paper retainer according to the present invention, the outermost layer of the winding paper roll before tape application is applied regardless of the shape of the winding paper roll. Since the looseness can be prevented and the winding end can be prevented from being displaced when the tape is applied, automation of the winding end tape application of the winding paper roll can be achieved.
