  Next, the operation of the band sticking device configured as described above will be described in relation to the sticking method.

  The uppermost band W stacked in the storage unit 16 is sucked and held by the suction cup 40a, one end of the band W is wound upward, and the moving mechanism 38 moves toward the supply position by the moving mechanism 44. The uppermost band W is taken out from the storage unit 16 and transferred toward the band conveyance device 20, and is loaded with the band W lying on the loading surface 48b of the conveyance bodies 48, 48 located at the receiving position. (See FIGS. 6 and 7).

  The band W is sucked and held on the mounting surface 48 b of the transport body 48, the transport mechanism 48 is moved toward the advance position by the operating mechanism 60, and the band W is moved on the fixed bed 50. At this time, the upstream end of the belt W is supported by the protrusion 62 of the transport body 48, and the belt W is transported satisfactorily during transport even when a suction failure occurs. Then, the left and right sides of the band W transported to the application preparation position S as the transport body 48 moves to the advance position are placed on the movable bed 52 located at the application preparation position S.

  At the timing when the container 10 conveyed by the introduction conveyor 12 is detected by the article sensor 13 and arrives at the crossover, the traveling of the introduction conveyor 12 and the conveyance conveyor 14 is stopped. The left and right sticking arms 70, 70 waiting above the sticking preparation position S are lowered and pressed against the left and right ends of the strip W on the movable bed 52, and the adhesive tape 22 held by suction on the sticking arm 70. The start end 22a is affixed to the left and right ends of the top surface of the band W (see FIG. 8A). Since the belt W is adsorbed and held on the transport body 48, the sticking position of the adhesive tape 22 is prevented from being shifted.

  Next, the transport body 48 retreats to the receiving position, and the left and right sticking arms 70 and 70 are lifted to lift the band W with the sticking tape 22 attached to both ends from the movable bed 52. Then, the movable bed 52 is retracted to the retracted position by the operating mechanism 60, and the lower part of the pasting preparation position S is opened.

  Both the pasting arms 70 and 70 are lowered by the synchronous operation of the elevating mechanism 76 while maintaining a gap, and the central portion of the strip W holding both left and right ends is directed to the top surface of the container 10 (FIG. 8). (See (b)). Further, as the strip W is directed to the top of the container, the holding cylinder 68 is operated to release the holding of the pressing body 64 at the retracted position, so that the pressing body 64 is lowered, and the center is formed at the crossover portion. The belt W is held on the container by the pressing material 64 a and the connecting material 64 b on the top surface of the container 10 positioned on the belt conveyor 26, and is pressed against the conveyor 26 together with the container 10 by the weight of the pressing body 64.

  Next, the operation of the traversing mechanism 74 and the elevating mechanism 76 causes each sticking arm 70 to approach the side surface of the container 10 while simultaneously descending the left and right sides of the container 10. In addition, since the sticking force of the adhesive tape 22 affixed with respect to the strip W is superior to the suction force by the said 1st adsorption | suction part 87a, the start end part 22a of the adhesion tape 22 adsorbed and hold | maintained by the 1st adsorption | suction part 87a. After the start end portion 22a of the adhesive tape 22 applied by the application arm 70 is attached to the band W, the adhesive tape 22 is pulled out from the tape roll 86 by the operation of the application arm 70 descending and approaching the side of the container. When the pressure-sensitive adhesive tape 22 is pulled out to a required length and the pressure-sensitive adhesive tape 22 is cut by the cutter 90, the pressure-sensitive adhesive tape 22 attached to the band W extends from the end of the band W by an amount corresponding to the required length. The gap T between the left and right belt conveyors 28 of the introduction conveyor 12 and the transfer conveyor 14 allows the sticking arm 70 to move toward the bottom surface of the container 10. The extending end 22b of the tape piece extending from the band W is held by the suction force of the second suction portion 87b until it is attached to the container 10. The start end portion 22 a of the adhesive tape 22 drawn out from the tape roll 86 is sucked and held at the tip of the sticking arm 70 and stands by. Subsequently, each sticking arm 70 is slightly lowered corresponding to the shape of the side surface of the container 10 so that the extended end 22b of the tape is released from the tip of the arm while receiving the suction force of the second suction portion 87b. The both ends of the strip W are taped without being bumped against the side surface of the container body 10a (see FIG. 8C).

  Next, the sticking arm 70 traverses away from the container 10 and rises to return to the sticking start position. Further, the holding cylinder 68 is operated, and the pressing body 64 is moved to the retracted position. Further, the introduction conveyor 12 and the transport conveyor 14 start to travel, and the container 10 around which the band W is wound is transported toward the carry-out side by the transport conveyor 14.

  When different packaging varieties such as a container size and a container shape are selected and set by the touch panel, the operation data of the traversing mechanism 74 and the lifting mechanism 76 related to the pasting operation based on the set value in relation to the container 10. Is changed and the operation is controlled. Thereby, the strip W is taped well to the various containers 10.

  In the pasting apparatus of the embodiment, the band W can be automatically pasted on the container 10 without much manpower. In addition, a uniform product with no variation in the position where the band W is applied and the tension applied can be mass-produced.

  In the affixing device of the embodiment, the belt W positioned and placed on the placing part (movable bed 52) at the affixing preparation position S set above the transfer part between the introduction conveyor 12 and the transport conveyor 14 is adhesive tape 22 at both ends. The movable bed 52 that has supported the band W from the lower side is retreated to the upstream side in the band conveyance direction so that the lower side of the application preparation position S is opened. Therefore, the band W held by the sticking arm 70 can be lowered and wound around the container 10 as it is. That is, since it is not necessary to move the band W held by the sticking arm 70 back and forth in the container transport direction, it is possible to suppress the winding position of the band W around the container 10 from being shifted. Moreover, since the movable bed 52 moves horizontally between the advance position facing the application preparation position S and the retracted position, it is necessary to allow the movement of the movable bed 52 for opening the lower part of the application preparation position S. Can be made smaller. That is, the distance between the application preparation position S and the top surface of the container 10 is shortened, and the posture of the web W is lowered until the paper sheet W held by the application arm 70 is lowered and applied to the top surface of the container 10. The change can be suppressed, and the shift of the winding position of the belt W can be more reliably prevented.

  Further, in the pasting device of the embodiment, the belt W placed on the fixed bed 50 is transferred to the movable bed 52 waiting at the pasting preparation position S by the transport body 48, so that it can be moved by the pasting arm 70. While the adhesive tape 22 is affixed to the band W on the bed 52, the transport body 48 can be retracted to the receiving position and the next band W can be received, and the work efficiency can be improved. In addition, since the strips W stored in the storage unit 16 are taken out and supplied one by one to the transport body 48 at the receiving position, the transport of the strip W to the transport body 48 can be satisfactorily performed.

  Further, in the pasting device of the embodiment, the operation of the pasting arm 70 is controlled so that the adhesive tape 22 is pulled out from the tape roll 86 when the strip W addressed to the top surface of the container 10 is guided and wound around the bottom surface of the container 10. Since the contact portion of the strip W with the container top surface becomes a resistance when the tape is pulled out, it is possible to uniformly extend the pasting margin when the strip W is displaced or when the adhesive tape 22 is pulled out. Both ends of the band W can be securely attached to the container body 10a.

(6) The belt W held on the application arm 70 at the application preparation position S is moved back and forth from the application preparation position S, and is moved down to avoid the application preparation position S. The form to be made can be adopted. In this case, it is possible to adopt a form in which after the belt W is lowered from the sticking preparation position S, the sticking arm 70 is moved back and forth in the container transport direction and the belt W is applied to the top surface of the container 10.
(7) The configuration is not limited to the configuration in which the adhesive tape 22 is pulled out from the tape roll 86 after the strip W is addressed to the top surface of the container 10, and the adhesive strip 22 is pasted on the strip W at the pasting preparation position S. A configuration in which the adhesive arms 70 and 70 are moved away from each other and the adhesive tape 22 is pulled out can be adopted until the adhesive is applied to the top of the container.
(8) In the process of attaching the strip W to the container 10, the conveyance of the container 10 by the conveyors 12 and 14 is stopped. For example, as illustrated in Japanese Patent Application No. 2007-283344, A configuration may be adopted in which the sticking arm 70 is moved to the downstream side together with the container 10 and the sticking operation of the band W is performed during the movement of the container 10 toward the downstream side.
(9) The introduction conveyor 12 is composed of three belt conveyors 26, 28, and 28 to form a gap T that prevents interference with the sticking arm 70. For example, Japanese Patent Application No. 2010-242803 is exemplified. As described above, the opposing end portions of the introduction conveyor 12 and the carry-in conveyor 14 can be moved toward and away from each other, and a holding means for placing and holding the bottom surface of the container 10 by a narrow area is provided at the time of the separation. You may make it prevent interference with the conveyors 12 and 14 and the sticking arm 70. FIG.
