DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for treating the winding end of a web so that the web is not loosened when winding the web to produce a winding roll. The present invention relates to a roll manufacturing method and a winding roll manufacturing apparatus having such an apparatus.

[0002]

2. Description of the Related Art Conventionally, when a web-shaped paper (hereinafter referred to as a "wound paper") is wound on a take-up roll in a paper machine winder, for example, bonding is performed so that the winding end is not peeled off when the winding is completed. The end of the winding is fixed with tape. 7 and 8 are views showing a method of fixing the end of a take-up roll wound by a conventional paper machine winder, FIG. 7 is a view showing a method of fixing with an adhesive tape, and FIG. It is a figure which shows the fixing method with a plastic band.

[0003] A general fixing method using an adhesive tape includes:
As shown in FIG. 7, a short one-sided adhesive tape 2 is stuck from the outside at an appropriate interval and fixed (see FIG. 7A).
A double-sided adhesive tape 3 attached to the inside of the winding end and fixed in the width direction (see FIG. 7B), and a single-sided adhesive tape 4 fixed to the winding end from the outside in the width direction of the roll (FIG. 7)
(C)).

Further, since the outer layer is easily loosened particularly with thick paper, as shown in FIG. 8, a band 5 made of a steel band or a plastic is hung on the end of the winding roll 1 and tightened so that the winding is not loosened. However, such banding requires the installation of a banding device in a location separate from the winder,
In addition to the increase in equipment costs, the work requires extra steps and time.

[0005] By the way, there are various types of devices for fixing the winding end portion of the take-up roll with tape, such as a device for processing inside a winder and a device for processing outside the machine away from the winder. It is desirable to perform processing in a winder from the surface side. As a method for this, a tail seal method (winding end processing method) of a roll of paper roll is proposed in Japanese Patent No. 2559660.

FIG. 9 is a schematic view showing the outline of a tail seal device (winding end processing device) proposed in Japanese Patent No. 2559660, and FIG. 9A is a diagram in which winding paper is wound using a winding drum. It is a diagram showing a state of winding on a take-up roll,
(B) is a figure which shows a mode that a roll paper is cut | disconnected at a winding end part. As shown in FIG. 9, the tail seal device includes a pair of winding drums 10, 10, a touch roll 11, a tape sticking unit 12, an arm 15, a push roll 16, and a cutter 17 as essential parts.

[0007] As shown in FIG.
It is wound on a winding roll (roll) 9 via one winding drum 10. One end of an arm 15 is supported by the one winding drum 10 so as to be rotatable around the rotation axis of the winding drum 10, and a push roll 16 is supported by the other end of the arm 15. A touch roll 11 is provided below the winding drum 10, and a tape sticking unit 12 is provided to face the touch roll 11. The cutter 17 is driven by an arm (not shown) rotatable around the rotation axis of the take-up drum 10 so as to come into contact with and separate from the take-up paper 8.

[0008] In the tail seal where the double-sided adhesive tape 13 is adhered to the winding end portion, the winding paper 8 is wound on a winding roll 9.
During the winding, the double-sided adhesive tape 13 of the tape applying unit 12 is attached to the touch roll 11 in advance. When the touch roll 11 is pressed against the winding drum 10 when the winding end passes, immediately before the double-sided adhesive tape 14 on the touch roll 11 is attached to the winding roll 9, FIG.
As shown in (b), the arm 15 is rotated, and the take-up roll 9 is pushed by the push roll 16 so that one of the winding drums 1 is rotated.
The take-up roll 9 is released from 0. The cutter 17 is operated in the separated gap to cut the web 8. Winding roll 9
Is further rotated, the double-sided adhesive tape 14 is
6 and the take-up roll 9, and the winding end is adhered by the nip pressure between the take-up roll 9 and the press roll 14.
Therefore, in this tail seal device, FIG.
The processing at the winding end as shown in FIG.

[0009]

However, since the web 8 is cut before the web end is fastened with the double-sided adhesive tape, the web end is fastened in a state where the tension of the web 8 is not maintained. There is a problem that winding looseness occurs at the winding end. When the winding is loosened, the force for tightening the paper layers in the radial direction of the roll is weakened, so that the winding of the surface layer is loosened, and when the roll is conveyed in a later step and conveyed, as shown in FIG. Paper is likely to be misaligned due to a shift in the width direction.
When the paper is vertically stored with the rolls shifted in the width direction in this manner, the shifted portions are crushed and become waste paper, so that the band is not loosened by banding with a band such as a steel band or plastic. You need to do that. However, this band must be removed at the final stage, such as in a printing plant, which is time-consuming and requires disposal of the removed band as waste, which is a burden on work efficiency and costs. There was a problem that.

1 acts in the direction of flow of the web (web-like paper, hereinafter referred to as rolled paper) 8 to be applied.

That is, in the tape sticking unit 30,
First, the double-sided adhesive tape 31 wound in a roll shape is hung on the supply reel 32. Then, the front end of the double-sided adhesive tape 31 is rewound, and is fixed to the take-up reel 33 via the guide roll 37 and the press roll 34. After this, the presser roll 34
Is driven by the cylinder 35, moves toward the winding drum 10, and transfers the double-sided adhesive tape body to the winding paper 8. At this time, the backing material is wound around the take-up reel 33. When the double-sided adhesive tape main body is moved by a necessary length, the cylinder 35 is driven to separate the pressing roll 34 from the web paper 8, and the double-sided adhesive tape main body is cut by the tape cutter 36. In this manner, the double-sided adhesive tape body cut and attached to the web 8 by the tape cutter 36 to a predetermined length is referred to as a double-sided adhesive tape piece (adhesive member) 21.

Disconnect. When the web 8 is cut, the tension of the web 8 near the cut portion is removed, but the double-sided adhesive tape piece 21 is cut.
Is already fastened to and fixed to the winding end, so that the winding at the winding end does not loosen. Further, since the double-sided adhesive tape piece 21 is stuck sufficiently long in the longitudinal direction of the web 8, the winding end can be firmly fixed, and even if the timing of cutting the web 8 with the cutter 17 is slightly shifted, Processing is performed reliably.

After the winding end process is performed and cut out by the cutter 17, the remaining portion is wound up by a winding roll 20 and taken out as a roll as shown in FIG. The winding roll manufacturing apparatus and method according to the first embodiment of the present invention are configured as described above, so that the winding end of the winding paper 8 is fastened and fixed in a tensioned state, and then the downstream side is fixed. Since the winding paper 8 on the side is cut, a winding roll 20 without winding slack can be obtained. Therefore, as shown in FIG. 10, it is possible to avoid a problem that the rolled paper 8 in the surface layer portion is shifted in the width direction and becomes uneven.

Further, since the above-described operation is performed in parallel with the step of winding the winding paper 8, a tape is attached to the end of the winding by using another device, or a belt, plastic, or the like is used. It is not necessary to tighten and reinforce with a band, which contributes to reduction of equipment cost and improvement of work efficiency.
Further, since the double-sided adhesive tape piece 21 is stuck sufficiently long in the longitudinal direction of the web 8, the winding end can be firmly fixed, and even if the timing of cutting the web 8 with the cutter 17 is slightly shifted, The processing is reliably performed, and the winding roll 20 without winding slack can be obtained.

By configuring the winding roll manufacturing apparatus and method by using the winding roll end processing apparatus and method, a winding roll having a simple configuration and no slack can be manufactured.

The cutter 43 is driven forward and backward by an arm (not shown) having the same rotation axis as the rotation axis of the winding drum 40.

As shown in FIG. 5, when the cut portion at the winding end comes to a predetermined position, the arm 42 is driven by the stand 41 so that the winding roll 20 is separated from and separated from the winding drum 40, and the presser roll 44 is moved. It rises at an appropriate timing and presses the winding end. Then, the cutter 43 is advanced to a position near the web 8 and the winding end is cut. After the cutting, no tension is applied to the winding paper 8, but since the tip of the double-sided adhesive tape piece 21 is already stuck and fixed in a state of tension, the tension of the entire winding end is sufficiently maintained. I have.
Then, similarly to the first embodiment, the double-sided adhesive tape piece 21 is stuck sufficiently long in the longitudinal direction of the web paper 8 so that the end of the web can be firmly fixed and the web paper 8 is cut by the cutter 43. Even if the timing of the winding is slightly shifted, the winding end processing is reliably performed.

After the winding end is cut, the take-up roll 20 is driven and rotated by the center 42a, and the remaining portion is pressed by the press roll 44 to be completely taken up. Note that the double-sided adhesive tape piece 21 may be pressed and held by the take-up roll 20 by the holding roll 44 instead of being held by the nip pressure between the take-up drum 40 and the take-up roll 20.

Since the winding roll manufacturing apparatus and method according to the second embodiment of the present invention are configured as described above, similarly to the first embodiment, the winding end of the winding paper 8 is tensioned. After being fixed in the hooked state, the winding paper 8 on the downstream side is cut, so that the winding roll 20 without winding slack can be obtained. In addition, since the above-described operation is performed in parallel with the step of winding the winding paper 8, a tape is attached to the end of the winding paper using another device and fixed, or a band such as a steel band or plastic is used. Since there is no need to tighten or reinforce, it contributes to reduction of equipment costs and improvement of work efficiency.

Further, the double-sided adhesive tape piece 21 is
Is sufficiently long in the longitudinal direction, so that the winding end portion can be firmly fixed, and even if the timing of cutting the web 8 with the cutter 17 is slightly shifted, the winding end processing is reliably performed, and the winding without slackening is performed. A take-up roll 20 can be obtained. Next, a modified example of the second embodiment of the present invention will be described with reference to FIG. 6. In this modified example, as shown in FIG. The parts 40 are arranged apart from each other without providing a nip part. Except for this, the configuration is the same as that of the second embodiment.

The double-sided adhesive tape piece (adhesive member) 21 is affixed and fixed by the force in the roll center direction generated in the circumferential portion of the winding roll 20 by the tension of the winding paper 8 given by the center 42a. Double-sided adhesive tape piece 2
After the front end portion is fixed, the winding end is cut by the cutter (cutting portion) 43 as in the second embodiment.
