- the motor 52 is driven to rotate until a predetermined time preset in the timer 90b elapses from the time when the leading end of the tape piece A is detected based on the time (step S3). 5.
- the rotation of 2 is stopped (step S4).
- This predetermined time is defined by the edge 70 of the guide block 66 and the tip of the guide plate 74 by feeding out the tape band T after the tape piece A is detected by the optical sensor 62a. It is set equal to the time normally required for this piece of tape A to be accurately positioned within the overhang area of the tape strip running path.
- the controller 90 functions as an adjustment unit that adjusts the feeding amount of the tape band T.
- the air supply solenoid valve for the air cylinder 46 is opened, as indicated by the arrow in FIG.
- the air cylinder 46 is driven, and the pusher 48 attached to the piston rod drives the brake drum through the brake cylinder 40.
- step S5 the movement of the tape band T on the tape band traveling route in the feeding direction and the movement in the rewinding direction are restricted. That is, the movement of the tape band T is suppressed or prohibited (step S5).
- step S6 the forward movement solenoid valve of the air cylinder 94 of the horizontal slide mechanism is opened to supply air to the forward movement cylinder chamber of the air cylinder 94, and the attaching device 14 is moved horizontally toward the wrapping paper P as a whole. It is moved (step S6).
- step S7 limit switches
- the air supply to the air cylinder 94 is performed. Is stopped, and the attaching device 14 stops at the horizontal movement completion position. At this time, as shown in FIG.
- the tape piece A positioned in the overhang area between the edge 70 and the tip of the guide plate 74 is the suction surface of the suction compensator 8 that defines the wrapping paper traveling path section.
- the entire piece of tape is pressed against the wrapping paper P held by the wrapper, and the tape piece A is attached to the wrapping paper P.
- the movement of the tape band T along the tape band traveling route is restrained, and the path length of the tape band T from the lower guide roller 60 to the azupagidro roller 64 does not substantially change. . Therefore, the possibility that the tape piece A is attached to a position shifted from the wrapping paper P is eliminated or reduced.
- the lowering solenoid valve corresponding to the air cylinder 80 is driven to supply air to the lowering cylinder chamber of the air cylinder 80, thereby causing the piston rod 82 to extend and move up and down as shown by the arrow in FIG.
- the guide unit 68 moves toward the guide block 66, that is, descends (step S8).
- the tape belt running path is configured so that the mount D is largely bent at the guide surface 86 formed at the tip of the guide plate 74.
- the guide surface 86 is formed in a smooth arc shape as shown in FIG. 6, and the guide plate 74 is made of a material having a low coefficient of friction with the mount D.
- the guide plate 74 is made of a material having a low coefficient of friction with the mount D.
- the amount of movement of the bent portion of the mount D is equal to the amount of downward movement of the elevating guide unit 68. Therefore, as the elevating guide unit 68 moves downward, that is, as the guide plate 74 having the guide surface 86 for bending the mount D moves downward, the mount D is smoothly peeled off from the tape piece A.
- the elevating guide unit 68 is configured to elevate and lower in parallel with the mount D extending between the guide roller 76 and the upper guide roller 64. Therefore, while the elevating guide unit 68 descends, the pressure-contact state between the guide surface 86 of the guide plate 74 and the tape band T achieved by the horizontal movement of the attaching device 14 in steps S6 and S7 is maintained. You. That is, while the peeling of the backing sheet D from the tape piece A stuck to the wrapping paper P is performed by the downward movement of the elevating guide unit 68, the tape piece A is guided by the guide plate 74 via the backing sheet D. The possibility that the tape piece A is peeled off from the wrapping paper P by being pressed toward the wrapping paper P by the surface 86 is eliminated or reduced.
- steps S6 and S The pasting device 14 is further moved from the position where the horizontal movement of the pasting device 14 at 7 is completed to the wrapping paper P side, so that the pressing force of the tape plate T on the wrapping paper P side by the guide plate 74 is further increased. May be.
- step S9 the electromagnetic valve for downward movement is turned off.
- the supply of air to the downward movement cylinder chamber of the air cylinder 80 is stopped, and the lifting / lowering guide unit 68 is held at the downward movement completion position.
- the forward solenoid valve for the air cylinder 94 of the horizontal slide mechanism is closed, and the return solenoid valve is opened to supply air to the return cylinder chamber of the cylinder 94.
- step SI 1 when the attaching device 14 is returned to the standby position in FIG. 1 (step SI 1), the return solenoid valve for the air cylinder 94 is closed, and the horizontal movement of the attaching device 14 in the return direction is completed. . Further, the solenoid valve for upward movement corresponding to the lift guide unit 68 is turned on, air is supplied to the upward movement cylinder chamber of the air cylinder 80, and the lift guide unit 68 moves upward (step S12). When completion of the upward movement is detected by the limit switch (step S13), the air supply is stopped, the elevating guide unit 68 is held at the standby position, and the air supply solenoid valve corresponding to the air cylinder 46 is further provided.
- the attaching device 14 returns to the initial state, and waits for the next automatic connection operation of the paper roll supply unit 1. According to the pasting device 14 of the above-described embodiment, since the backing sheet D can be reliably peeled off at the same time as the tape piece A is pasted, the automatic connection operation of the rolled paper P by the supply unit 1 is greatly increased. Contribute.
- the attaching of the tape pieces A and the peeling of the backing sheet D by the attaching device 14 can be further improved. It can be done reliably.
- the detection of the tape piece A by the optical sensor 62a becomes easy, and the feeding accuracy of the tape strip T and the positioning accuracy of the tape piece A are further improved.
- the normal brake force of the holder 30 by the air cylinder 46, the normal brake force can be set low, and the tape 52 can be properly fed out by the motor 52. Then, when the mount D is peeled, the braking force is increased, and the free movement of the tape band T is restrained, so that the peeling operation can be reliably performed.
- the specific configuration of each part can be variously modified without being limited to the above-described embodiment.
- the guide block 66 and the guide plate 74 are members that are in sliding contact with the tape band T, but one or both of them may be replaced with rollers or pins.
- a take-up reel may be provided integrally with the elevating guide unit 68, and simultaneously with the lowering of the elevating guide unit 68, the reel may be rotated synchronously to take up the mount D. In this case, when the elevating guide unit 68 is raised next, the tape band T is fed out without rotating the reel.
- the web to which the tape piece A is to be applied is not limited to cigarette wrapping paper or chip vaporizer.
