As shown in FIG. 6, the film roll supporting and abutting means 17 is provided with a pair of fixed frames 88 and 89 on both sides of the conveyor 14 immediately below the rotary drum 4, and these fixed frames 88 and 89 are fixed to the fixed frames 88 and 89. Is provided with movable supporting members 90, 90 provided with fitting protrusions 89, 89 facing each other so as to be movable back and forth on the conveyor 14 side, and these movable supporting members 90, 90 are attached to the air cylinders 91, 91. Each of the fitting protrusions 89 is formed in a hollow cylindrical shape that can be lightly fitted to the paper tube 15 of the film roll 16, and the tip 89a is formed in a truncated cone shape. Has been done.

Therefore, according to the film roll supporting and abutting means 17, when the film roll 16 which is supported between the racks 14a, 14a of the conveyor 14 and is intermittently transferred comes to a position directly below the rotating drum 4, the position is appropriately adjusted. The position detecting means detects and the air cylinders 91, 91 are extended for a required time by the detection signal, whereby the fitting protrusions 89, 89 are advanced from the retracted position of the virtual line in the figure to the operating position shown by the solid line. ,
The film roll 16 is inserted and fitted at both ends of the paper tube 15.

In this case, the film roll 16 sent by the conveyor 14

In this state, the paper tube 15 is rotatable with respect to the fitting protrusions 89, 89, and is rotated following the rotation of the rotary drum 4. Therefore, the rotation of the paper tube 15 causes the peripheral surface of the film roll 16 to move. The tape 3 from the peripheral surface of the rotating drum 4 is wound while being transferred.

In FIG. 1, 92 and 93 are air injection nozzles, and the nozzle 92
Is a roller for pressing the tape 3 in the tape supply means 8.
When the tape 3 to be transferred from 29 to the peripheral surface of the rotary drum 4 is transferred, pressure air is jetted to the surface side of the tape 3 so that the tape 3 is easily separated from the pressing roller 29. Further, the nozzle 93 injects air to the bent portion of the tape 3 so that the rear end of the cut tape 3 is surely bent to the front side when the rear end of the cut tape 3 is folded back by the rotating piece 56. It is the one to be confused.

Next, a series of operations of the taping device having the above configuration will be described.

As shown in FIG. 1, the tape 3 is unwound from the reel 1, passes through the rollers 26, 27, 41, 28 and the pressing roller 29, and is attached to the tape 3 at a predetermined position on the peripheral surface of the rotary drum 4. The tape 3 is supplied with the coated surface on the front side.
It is assumed that the tip has already reached the cutting position directly below the cutter 12, and although not shown, the tape pulling mechanism 36 pulls it by hand to the pressing roller 29 side, and the gap between the roller 27 and the pressing roller 29 is reached. , And the cutter 12 is in a state immediately after the cutting by the blade 47 is finished.

When the drive shaft 6 starts to rotate from such a state, the rotary drum 4 is rotated by 90 ° in the initial stage of one rotation of the drive shaft 6 by the Geneva top mechanism, so that the support piece 55 and the support piece 55 positioned immediately below the cutter 12 are rotated. The rotating piece 56 moves 90 ° to reach the rotating disc 64 side.
During the rotation, the pressing roller 29 is driven to rotate at the same peripheral speed as the peripheral speed of the rotary drum 4, the tape 3 is supplied onto the peripheral surface of the rotary drum 4, and the supplied tape 3 is vacuum suction means 9
Is adsorbed and held on the peripheral surface of the rotary drum 4.

During the tape supply, the tape 3 is a tape pulling mechanism.
Since it is in the state where it is urged to the pressing roller 29 side by 36 in advance and the support roller 27 and the pressing roller 29 are bent, the pressure roller 29 is reliably supplied without slipping.

Further, the tape 3 fed from the reel 1 is a support roller.
When supplied to the peripheral surface of the rotary drum 4 via 26, 27, 41, 28 and the pressing roller 29, the adhesive coating surface side of the tape 3 is in contact with the peripheral surface of the pressing roller 29. The pressing roller 29 can pull the tape 3 toward the peripheral surface of the rotary drum 4 and reliably and easily supply the tape 3 onto the peripheral surface of the rotary drum 4 by the adhesive action of the tape 3 with the adhesive.

Then, when the rotary drum 4 completes the initial 90 ° rotation and enters the rest period, the pressing roller 29 stops and the tape 3
Is stopped, the tool rest 48 is lowered, and the tape 47 on the peripheral surface of the rotary drum 4 is cut by the tool 47. The tip of this cut tape 3 is from the cutting position by the cutter 47.
Although the tape 3 has been fed 90 °, since the tape 3 is the tip tape, the peeling portion forming means 13 only operates in the absence of the tape. Further, while the rotary drum 4 is at rest, the tape pull-in mechanism 36 manually pulls in the tape 3. When the rest period of the rotary drum 4 ends, one rotation of the drive shaft 6 ends.

When the continuously rotating drive shaft 6 shifts to the next one rotation, the rotating drum 4 rotates 90 ° in the initial stairs as described above,
By the time the 90 ° rotation of the rotating drum 4 is completed, the leading end of the preceding tape 3 reaches the film roll supporting and abutting means 17 side immediately below the rotating drum 4 and the tape 3
The rear end portion reaches the rotating disc 60 side while being held by the tape pressing surface 62 of the rotating piece 56. Then, at the time of rest of the rotary drum 4, the rear end portion of the tape 3 is reciprocally rotated by the reciprocal rotation of the rotary disc 60, so that the adhesive surface on the tape surface side as shown in FIG. Folded back and glued,
As a result, the stripped portion PGF is formed. Other operations during this period are similar to those described above.

Then, the rest of the rotary drum 4 is completed, and the driving shaft 6
When the rotary drum 4 starts to rotate 90 ° again for the next one rotation, the film roll supporting and abutting means 17 is actuated to move the film roll 16 on the conveyor 14 to the peripheral surface of the rotary drum 4. The film roll 16 is brought into contact with the front end of the tape 3 which is held, and rotates as the rotating drum 4 rotates
Is rotated, the tape 3 on the peripheral surface of the rotary drum 4 is wound around the peripheral surface of the film roll 16, and a peeling portion P is formed at the end of the winding tail of the tape 3 as shown in FIG. It will be.

After that, the support of the film roll 16 by the film roll supporting and abutting means 17 is released, and the film roll 16 on which the tape 3 is wound is dropped between the racks 14a, 14a of the conveyor 14 and transferred.

After that, the above operation is repeated, and the tape 3 with the peeling portion P is automatically and sequentially wound around the film roll 16 sent by the conveyor 14.

In the apparatus of the embodiment described above, all the operations of the rotary drum, the tape supply means, the cutter, and the tape rear end folding means are controlled by one drive source (motor), so that the structure is small and compact. As well as
The operation is easily controlled.

In implementing the present invention, instead of using one drive source as in this embodiment, a plurality of drive sources may be separately driven to set appropriate timings.

Further, although the rotary drum is driven to rotate intermittently in the embodiment, the rotary drum may be driven to rotate continuously.

(Operation and Effect of the Invention) In the taping device of the present invention, the rotary drum is rotationally driven in a fixed direction, and the tape is applied to the tape at a predetermined position on the peripheral surface of the drum so that the adhesive-coated surface is the front side. Thus, this tape is suction-held on the peripheral surface of the drum by the vacuum suction means. In this way, the tape which is sucked and held on the drum peripheral surface and continuously supplied is cut by the cutter at a fixed position, and the trailing end portion of the tape is folded back to the tape surface side by the peeling portion forming means. , Forming a stripped portion.

Thus, the tape having the stripped portion formed at the rear end moves along with the rotation of the rotary drum while being held on the drum peripheral surface, and at the fixed position, the front end of the tape is placed on the adherend to be wound. When the contact support means is brought into contact with the member to be wrapped that is conveyed by the conveyor, the member to be wound rotates following the rotation of the rotary drum, whereby the peripheral surface of the member to be wrapped is rotated. The tape on the peripheral surface of the drum is wound, and a peeling portion is formed at the end of the tape trailing end of the tape wound on the body to be wound.

As described above, according to the taping device of the present invention, a work of winding a tape of a predetermined length, one side of which is coated with an adhesive, around a roll-shaped member, and peeling off the tape at the end of the tail end of the tape. Since the work of forming the portion can be automatically performed in the same process, the taping work efficiency can be remarkably improved as compared with the conventional manual work.

In particular, according to the peeling portion forming means of this device, the tape supplied to the peripheral surface of the rotating drum by the tape supplying means with the adhesive coated surface on the front side is cut into a predetermined length by a cutter, By rotating the turning piece back and forth with the rear end of the cut tape positioned on the tape pressing surface, the rear end of the tape is surely folded back to the front side by the turning piece, The peeled portion can be formed at the rear end portion of the tape which is polymer-bonded to the tape portion on the peripheral surface and cut into a predetermined length.

As described above, since the peeling portion can be formed at the rear end portion of the tape supplied with the adhesive coated surface on the front side on the peripheral surface of the drum, this tape is used in the next step to support the wound body supporting and abutting means. When the tape is brought into contact with the wound body and is wound around the wound body, the tape having the peeled portion formed thereon can be accurately wound around the wound body from the tip end portion thereof as it is. The work of forming the peeling portion on the tape and the work of winding the tape around the member to be wrapped can be performed continuously.
