When cutting by means, the pressure-sensitive adhesive tape is pulled out from the pressure-sensitive adhesive tape roll, and the pressure sufficient to cut the pressure-sensitive adhesive tape does not act on the pressure-sensitive adhesive tape. There were many problems.

  Therefore, when the web paper is cut by the cutter, the pressure-sensitive adhesive tape stretched between the web paper and the pressing roller generates sufficient tension to cut the pressure-sensitive adhesive tape, and the web paper can be cut at a desired timing. A tape applicator was desired.

  An object of the present invention is to provide an adhesive tape sticking device for a paper threading device capable of solving the above-mentioned problems, and the configuration is made by a paper threading body that moves along a paper threading path of a rotary press.

Pressing on the outer peripheral surface of the pressing roller with the presser plate, and when the pressing roller is in the affixing position, it does not press the adhesive tape on the outer peripheral surface of the pressing roller with the pressing plate, and corresponds to the pressing roller And the receiving means provided so as to sandwich the paper threading body and the web paper that move downstream in the paper threading direction together with the pressing roller at the pasting position, and the adhesive tape is restricted from being pulled out from the adhesive tape roll. The cutting edge is in contact with the pressure-sensitive adhesive tape pull-out restricting means, and the pressure-sensitive adhesive tape after the paper threading body and the web paper are pasted, so that the cutting edge is cut and the standby position where the blade edge is separated is moved. And a pressing roller having an adhesive tape attached to the paper threading body and the web paper at the attaching position toward the standby position. After the movement starts, the cutting means moves to the cutting position between the paper thread or web paper and the outer peripheral surface of the pressing roller, and after the movement of the cutting means to the cutting position is finished, the pressure-sensitive adhesive tape pull-out regulating means is the pressure-sensitive adhesive tape roll. The adhesive tape is controlled to be pulled out from the press, and the presser plate presses the adhesive tape on the outer peripheral surface of the pressing roller, and the operation of the presser plate changes the path of the adhesive tape from the outer peripheral surface of the pressing roller to the cutting edge of the cutting means at once. In addition, the contact force of the adhesive tape to the blade edge is increased.

  In the adhesive tape pasting device of the paper threading device, the press plate is processed so that at least a portion in contact with the adhesive surface of the adhesive tape reduces the adhesive force of the adhesive surface, and the adhesive tape pull-out restricting means includes a pressing roller. It is provided to restrict rotation and to prevent the adhesive tape from being pulled out of the adhesive tape roll by pressing the adhesive tape against the pressing roller, so that at least the part in contact with the adhesive surface of the adhesive tape reduces the adhesive force of the adhesive surface I processed it.

And the receiving roller 301, the adhesive tape Ma, the attachment La, and the turn bar paper W1 attached to the attachment La are sandwiched (FIG. 6).

  At the same time, the driving roller 6 of the second paper threading body moving device B2 starts to rotate, and the paper threading body L starts to move with the turn bar paper W1 aligned with the moving direction and the traveling speed.

  As shown in FIG. 6, as the paper thread L and the turn bar paper W1 move together, the adhesive tape Ma is pulled out from the adhesive tape roll M and reaches the outer peripheral surface of the pressing roller 111. And the adhesive surface is pressed against and attached to the turn bar paper W1 moved onto the peripheral surface of the receiving roller 301 (FIG. 7).

  At this time, a slight change in tension acting on the adhesive tape Ma drawn from the adhesive tape roll M is absorbed by the arm 104 supporting the guide roller 106 by angular displacement against the force of the spring 107.

  The movement of the paper thread L and the turn bar paper W1 by the second paper thread moving device B2 is performed for a predetermined distance, and the adhesive tape Ma is pasted over the attachment La and the turn bar paper W1. The solenoid valve of the pressure cylinder 203 is switched, the rod of the fluid pressure cylinder 203 is retracted, the adhesive tape holding means 100 is raised, and the pressing roller 111 moves from the sticking position to the standby position.

  During this movement, the movement of the paper thread L and the turn bar paper W1 is continued, and when the upward movement of the adhesive tape holding means 100 is completed, the adhesive tape Ma moves along with the turn bar paper W1. It is in a state of being inclined and spanned between a position downstream from the receiving roller 301 on the upper surface and a standby position of the pressing roller 111 (FIG. 8).

  In addition, when an appropriate timing after the rod of the fluid pressure cylinder 203 starts to be degenerated, for example, when the rod of the fluid pressure cylinder 203 is degenerated, a solenoid valve (not shown) connected to the fluid pressure cylinder 406 is switched, The rod of the fluid pressure cylinder 406 is extended, the arm 404 is angularly displaced in the clockwise direction in FIG. 2 and the waiting cutter 401 is lowered, and the cutting edge of the cutter 401 comes from the receiving roller 301 on the upper surface of the turn bar paper W1. Between the downstream position and the outer peripheral surface of the pressing roller 111 that has moved to the standby position, the adhesive tape Ma in a state of being inclined and contacted is pressed down from above. At the same time or slightly later, the solenoid valve of the fluid pressure cylinder 115 is switched, the rod of the fluid pressure cylinder 115 is retracted, the bell crank arm 113 is angularly displaced, and the pressing block 501 and the pressing plate 114 are pressed against the pressing roller 111. The pressing block 501 strongly presses the adhesive tape Ma against the pressing roller 111 with the pressing surface 501a, restricts the rotation of the pressing roller 111, and the pressing plate 114 has an adhesive tape with the adhesive tape pressing surface 114a. Ma is pressed into the groove 111 a on the outer peripheral surface of the pressing roller 111.

  By the operation of the pressing block 501 and the pressing plate 114, the path of the adhesive tape Ma from the outer peripheral surface of the pressing roller 111 to the cutting edge of the cutter 401 is changed from a linear shape indicated by a two-dot chain line in FIG. While the shape changes to a shape refracted at the tip of 114, the adhesive tape Ma is pressed against the outer peripheral surface of the pressing roller 111 whose rotation is restricted, and the pull-out of the adhesive tape Ma from the adhesive tape roll M is restricted, and the adhesive tape Ma. The tension acting on the surface increases at a stretch. As a result, the contact force of the adhesive tape Ma to the cutting edge of the cutter 401 increases at a stretch. In addition, the refraction angle of the adhesive tape Ma that is refracted by contacting the blade edge of the cutter 401 (the angle on the cutter 401 side formed by the upstream and downstream adhesive tapes Ma of the blade edge of the cutter 401) is reduced.

  Accordingly, the increased contact force concentrates on the refracted portion of the adhesive tape Ma having a small refraction angle and acts at once, and the adhesive tape Ma is immediately cut. The tail portion of the cut adhesive tape Ma falls on the turn bar paper W1 and sticks to the turn bar paper W1.

  When a predetermined time elapses after the operation of the fluid pressure cylinder 115, the solenoid valve of the fluid pressure cylinder 406 is switched as shown in FIG. 9, the rod of the fluid pressure cylinder 406 is retracted, and the arm 404 is angularly displaced. Then, the cutter 401 rises and moves to a standby state.

  As described above, the operation of attaching the paper thread L to the attachment La with the adhesive tape Ma is completed. The paper threading body L is moved as it is according to the guide rail G, and the paper threading is performed to the second paper threading path Q2 of the turn bar paper W1.

  In the pre-sticking preparatory operation and the sticking operation, the adhesive tape pressing surface 114a of the pressing plate 114 and the pressing surface 501a of the pressing block 501 have reduced adhesive force with the adhesive surface, and the adhesive surface of the adhesive tape Ma. When being separated from each other, separation can be performed very easily.
