Description

  The present invention relates to a tape applicator used for continuously adhering various attached tapes such as a watertight tape and a decorative tape to a long material continuously in an automatic operation while removing a release paper attached to the tape. .

  Adhesive tape with adhesive on one or both sides prevents the adhesive force from deteriorating due to dust, dust, etc. adhering to the adhesive before it is attached to the adherend, and its handling At this time, in order to prevent the workability from being deteriorated due to adhesion to other materials, release paper is laminated on the surface of the pressure-sensitive adhesive. In particular, in order to improve handling such as transport and storage, when the supplied tape is produced and supplied in a roll state, the wound tape is separated from the adhesive surface in order to prevent the wound tapes from adhering to each other and becoming difficult to separate. Produced with paper pattern.

  When these attached tapes with release paper are used, the release paper is peeled off immediately before it is attached to the adherend, and thus the release release paper needs to be separately collected. In particular, in a machine device that automatically or semi-automatically attaches an adherent tape to an adherend, for example, using a vacuum device, the release paper separated from the tape supply roll is sucked into a reservoir to collect the release paper. (For example, refer to Patent Document 1).

Further, the chuck portion 23a of the picking means 23 transfers the long materials W one by one onto the input conveyor 21 by a signal sent from a microcomputer that controls the movement of the entire line L. The long material W waiting on the input conveyor 21 is controlled by the microcomputer and carried into the tape applicator 1.

  As shown in FIG. 1, the tape applicator 1 loaded with the long material W peels off the base B, the tape supply unit 2, and the release paper 3 attached to the tape T, and winds it. A release paper peeling means 4 for forming the release paper roll 7, an attaching means 5 for attaching the tape T to the long material W, and a tape cutting unit 6 for cutting the tape T between the long materials W are provided.

  The base B includes a gantry B1 and a device base B2 supported on the gantry B1. The gantry B1 is provided with a roll conveyor 25 including a plurality of rolls that are rotated by a well-known interlocking mechanism such as a chain (not shown), which is given rotational force by a power source 24 including an electric motor 24A. The long material W is fed onto the roll conveyor 25.

  The tape supply unit 2 includes a support column 26 erected on the upper portion of the apparatus base B2 and a horizontal supply shaft 27 provided on the upper portion of the support column 26. The release shaft 3 is attached to the supply shaft 27. A tape roll TR formed by winding the tape T is rotatably mounted. The tape T is pulled by advancing the long material W to which the tip of the tape T is adhered, and the tape roll TR is rotated by this tensile force to feed the tape T.

  As shown in FIG. 2, the release paper peeling means 4 is formed in the apparatus base B2, and includes a first peeling roller R1, a second peeling roller R2 facing the first peeling roller R1, and a winding. A take-up shaft 8 is provided.

It moves between a position where the tape T can be clamped and a position away from the first peeling roller R1.

  The winding shaft 8 is formed behind the first peeling roller R1, and supports a release paper roll 7 formed by winding the release paper 3. As shown in FIG. 4, a pulley 9a formed at the end of the winding shaft 8, a pulley 9b formed at the end of the shaft 30 with which the first peeling roller R1 is fitted, and both pulleys By providing the conduction means 9 comprising the belt 9c laid between 9a and 9b, the winding shaft 8 rotates in conjunction with the rotation of the first peeling roller R1. When the tape T that is pulled and fed by the advance of the long material W passes between the first peeling roller R1 and the second peeling roller R2 that sandwich the tape T, the first peeling is caused by friction. A rotational force is applied to the roller R1. The rotational force is transmitted to the take-up shaft 8 through the conduction means 9 and the release paper roll 7 rotates, so that the release paper 3 is pulled toward the release paper roll 7, thereby the first and second After passing between the release rollers R <b> 1 and R <b> 2, the release paper 3 is released from the tape and wound on the release paper roll 7. Therefore, since the release paper roll 7 is rotated and wound by the rotational force of the first peeling roller R1, the apparatus can be simplified without providing a separate drive source, and the release paper 3 can be peeled and taken up. It can be done smoothly. Further, the release paper 3 that has been peeled off is collected in a very compact form, so that it is easy to handle, and the work space is small and the workability is also good. Further, since the capacity for temporarily storing the release paper 3 in the apparatus is reduced, the apparatus can be downsized.

  Note that the outer diameter of the release paper roll 7 gradually increases as the winding progresses, and the winding length per rotation varies depending on the change of the outer diameter, so that the release paper 3 having the same length can be wound. The rotation speed of the winding shaft 8 increases or decreases. However, in this example, the transmission means 9 is configured such that, for example, the tension of the belt 9c installed between the pulleys 9a and 9b is set to be slightly small, so that the belt 9c exceeds the pulleys 9a and 9b when a certain load is exceeded. The slipping structure is used, and the increase / decrease in the number of rotations of the winding shaft 8 due to the change in the outer diameter of the release paper roll 7 is adjusted. Therefore, an appropriate tension can always be applied to the release paper 3, and the peeling and winding can be facilitated. Further, the transmission rate of the conduction means 9 can be adjusted by configuring the pulleys 9a, 9b or the belt 9c with a material having a small friction coefficient.

The starting end of the tape T that has passed through the gap between the first peeling roller R1 and the second peeling roller R2 is attached to the front end portion of the long material W. Next, the cylinder 28 is used to shift the second peeling roller R2 toward the first peeling roller R1 to sandwich the tape T, and the pressing roller 5b is shifted downward to make the long material W and The tape T affixed thereon is pressed, and in this state, the roll conveyor 25 is driven forward to start automatic affixing.

  When a new tape roll TR is mounted, the release paper 3 at the start end of the tape T peeled off by the operator is connected to the end of the release paper 3 wound around the release paper roll 7 with an adhesive tape. When the release paper roll 7 reaches a predetermined winding amount, the tape applicator 1 is stopped, the release paper roll 7 is removed from the take-up shaft 8, and a new take-up core 7a is attached to the take-up shaft 8. At the same time, the new start end of the release paper 3 is fixed to the winding core 7a with an adhesive tape. In this example, the supply shaft 27 of the tape supply unit 2 and the winding shaft 8 are formed to have the same diameter, and the used roll core 31 used for the tape roll TR is wound around the release paper roll 7. Since the core 7a is recycled, it is preferable in that resources can be used effectively.
