Is pressed against the winding end 5 a held by the suction plate 22. In this state, the mount 33 is moved in the direction of the arrow in FIG. Then, the double-sided adhesive tape 38 is paid out from the supply reel 37, and the tape body of the double-sided adhesive tape 38 is transferred to the winding end 5a (the transferred tape body is referred to as a double-sided adhesive tape piece (adhesive member) 38a), Is wound on a take-up reel 39.

After the tape piece 38a has been applied to the vicinity of the other end face of the take-up roll 5, the movable table 35 is moved by the cylinder 36 in a direction of coming and going from the end 5a, and the pressing roll 40 is separated from the end of the wind. When the mounting table 33 is slightly moved along the rail 32 in this state, the main body of the tape 38 is torn. Then, the movable table 35 is moved to the winding end 5 by the cylinder 36.
a, and the remaining portion of the double-sided adhesive tape piece 38a that has been torn off by the pressing roll 40 is pressed. When the pressing is completed, the movable table is again moved by the cylinder 36 in the direction of coming and going from the winding end 5a to separate the pressing roll 40 from the paper, and the tape application in the horizontal direction is completed.

Next, the defective portion of the winding end 5a is cut. First, the tape application device 30 is moved along the rail 32 so that the rotary cutter 54 comes to one end of the winding end 5a. Then, the cylinder 51 is operated to bring the rotary cutter 54 into contact with the winding end 5a. At this time, the rotary cutter 54
Is adjusted so that the cutting edge is positioned in the groove provided in the suction plate 22, so that the rotary cutter 54 directly contacts the suction plate 22.
Avoid contact with By moving the tape applying device 30 to the other end of the winding end 5a while rotating the rotary cutter 54 with the motor 53, the winding end 5a is moved at a fixed distance from the position of the attached double-sided adhesive tape piece 38a. It is cut (the cut end face is referred to as a cut end 5b).

When the tape application device 30 completes the application of the tape in the web width direction and the cutting of the defective portion, the tape application device 30 is moved in the width direction of the take-up roll 5 so that there is no interference when the take-up roll 5 is transported. Evacuate to the position
As shown in (5), the temporary fixing tape applying device 60 is raised to the tape supply start position. This tape supply start position is a position where the front end of the temporary fixing tape is slightly higher than the cut end 5b previously cut by the rotary cutter 54. At this position, the movable table 66 is moved toward the winding end 5a by the cylinder 68, and the pressing roll 69 is pressed against the winding end 5a. Further, the cylinder 71 is operated to supply the supply roll 70 to the winding end 5.
Press on a. In this way, the leading end of the temporary fixing tape 64 held between the supply roll 70 and the temporary fixing tape retainer 74 is pressed against the winding end 5a. In this state, when the temporary fixing tape applying device 60 is moved downward in the drawing, the temporary fixing tape 64 is applied to the winding end. When the leading end of the tape 64 affixed to the winding end 5a passes through the presser roll 69, the cylinder 71 is operated to pull the supply roll 70 back to the position shown in FIG. When the temporary fixing tape 64 is supplied beyond the winding end and the temporary fixing tape applying device 30 reaches the tape supply completion position, the cylinder 73 is operated to operate the cutter 72.

The leading end of the cut tape 64 on the supply reel 65 side is held between the supply roll 70 and the tape holder 74. The tape supply completion position is set below the cut end 5b, and the temporary fixing tape piece 64a is affixed so that both ends thereof respectively cover the suction plate 22 and the winding end 5a.

FIG. 4 shows the state of the adhesive tapes 38a and 64a attached to the winding end 5a at this stage. In this manner, the temporary fixing tape (one-sided adhesive kraft tape piece) 64a is attached to the suction plate 22 simultaneously with the paper. Therefore, the surface of the suction plate 22 is non-adhesive processed with a material such as silicon or fluorine so that the temporary fixing tape 64a does not strongly adhere to the suction plate 22.

Next, the take-up roll 5 is rotated by a winding means (not shown) to wind up the winding end 5a, and the temporary fixing tape 64a is brought below the holding device 80. Therefore,
As shown in FIG. 5, when the presser plate 88 is rotated to an operation position for pressing the temporary fixing tape 64a, and the winding roll 5 is further rotated while being pressed by the cylinder 84, the lower half of the temporary fixing tape 64a is attached to the winding roll 5. Thus, the winding end 5a is fixed. After the operation of the presser plate 88 is completed, the tailoring operation is completed when the presser plate 88 is placed at a standby position indicated by a chain line so as not to hinder the transfer of the winding roll 5, and is conveyed to the operation position of the next process.

As described above, according to the winding end processing apparatus and method according to the present embodiment, the winding roll 5 on which the web 1 has been wound on the reel stand 2 has the outer surface of the winding end 5 a by the tape application device 30. The double-sided adhesive tape 38 is affixed to the tape and is temporarily fixed by the temporary fixing tape applying device 60 and is conveyed to the winder 7, so that even if the winding roll 5 rotates due to vibration during conveyance, the unwinding does not occur. In addition, the double-sided adhesive tape piece 38a does not hit the floor or another machine, so that the adhesive surface does not become dirty or the additional surface is broken and the tape surface does not stick.

At this time, since the winding end 5a is affixed to the winding roll 5 main body with the temporary fixing tape piece 64a as a temporary fixing method, the apparatus can be simplified. Also, after the temporary fixing tape piece 64a is attached to the winding end 5a by the temporary fixing tape applying device 60, the winding roll 5 is rotated to wind up the winding end 5a to which the tape piece 64a is attached, and the pressing device 80 Since the tape piece 64a is pressed against the take-up roll 5 main body to fix the winding end portion 5a, the temporary fixing tape attaching device 60 and the pressing device 80 can be provided separately, and each device 60, 80 is simplified. be able to. Then, the pressing operation is further simplified by installing the pressing device 80 at a position where the pressing device 80 is wound around the winding end 5a winding roll 5 main body. That is, the configuration of the device can be simplified by installing the presser device 80 on the transport rail 6.

The winding end 5a is suctioned and held by a suction device through a plurality of holes provided in the suction plate 22, so that the winding end 5a is reliably held while the suction device 2 is held.
0 is simplified. Further, when the winding roll 5 thus processed is spliced by the winder 7, the temporary fixing tape 64a separates from the winding roll as shown in FIG. ), The leading edge of the paper is torn and remains on the take-up roll, but in any case, since it is the part of the ear cut off by the slitter of the winder, there is no effect on the loss of the product. Also, since the paper splicing process can be performed with the temporary fixing tape attached,
Extra work such as peeling off the temporary fixing tape before splicing is not required, and the work efficiency is improved.

The present invention is not limited to the above-described embodiment, but can be implemented in various modifications without departing from the spirit of the present invention. For example, the temporary fixing may be any as long as it can fix the winding end 5a to the winding roll 5 main body. Instead of attaching the single-sided adhesive kraft tape 64 to the outer surface of the winding end 5a, the temporary fixing is performed. A double-sided adhesive tape may be attached to the inner surface of 5a, or an adhesive may be applied.

The adhesive member at the time of splicing is a winding end 5a.
The adhesive may be applied instead of attaching the double-sided adhesive tape 38.
Further, the suction plate 22 may have any shape as long as it can suction and fix the winding end portion 5a for applying the double-sided adhesive tape 38 and the single-sided kraft tape 64, and a plurality of holes are provided in the surface. Instead of suctioning, a plurality of narrow slots leading to the suction box 21 are provided to suck the winding end 5a, and when the rotary cutter 54 cuts a defective portion of the winding end 5a, cutting is performed at the slot. You may do so.

[0033]

As described in detail above, according to the present invention,
Since the take-up roll is transported with the winding end portion temporarily fixed by the temporary fixing member, even if the take-up roll rotates during conveyance, the winding roll is not unwound, and the subsequent splicing operation with the winder can be performed. It can be performed smoothly (claims 1 and 4).

Further, the temporary fixing process can be performed smoothly by attaching a temporary fixing tape after attaching an adhesive member for splicing to the winding end portion (claim 2).
In addition, by attaching the single-sided adhesive tape from the outer surface of the web, the temporary fixing can be reliably performed with a simple configuration. Also, by suctioning and holding the winding end by a suction device through a plurality of holes provided in the suction plate,
The structure of the winding end holding means can be simplified (claim 5).

Since the provisionally fixing means has the winding means, the provisionally fixing member supply means and the fixing means can be separated from each other, so that the structure of the entire apparatus can be simplified. At this time, further simplification of the device can be realized by mounting the fixing means at a position where the fixing means does not interfere with the winding roll of the transport rail (claim 7).
