Description

  The present invention relates to an adhesive tape supply device that feeds the leading end side of an adhesive tape that is rewound from a rewinding device to a tape tip transfer work position and cuts the fed adhesive tape to a set dimension. As an adhesive tape, what formed the adhesive layer on the single side | surface or both surfaces of the sheet | seat consisting of a plastic film, metal foil, paper, etc. is used.

Conventionally, there is a method in which an adhesive tape that has been rewound from a rewinding device is cut into set dimensions and supplied to a predetermined location. For example, with the leading and trailing edges of the new and old webs butted together, the adhesive tape is applied across the entire width of the web while straddling the leading and trailing edges of the new and old webs, and the new and old webs are butt joined. There is a web splicing method and a splicing splicing device (Patent Document 1). The web butt splicing device is equipped with a tape holding device that can hold the adhesive tape on the holding surface in the adsorbed state so that it can move forward and backward. The tape holding device can be moved forward and backward until a standby position on either the left or right side of the new and old webs extending inward. Then, the supply of the adhesive tape to the standby tape holding device is performed manually by the operator, and the operator rewinds from the rewinding device and cuts to the set dimension, and the cut adhesive tape is transferred to the tape holding device. It is done to hand over.

And the first moving means 24 for winding / rewinding and the second moving means 25 for winding / rewinding are operated in synchronization with each other, and the adhesive tape is applied to the outer peripheral surface of the holding bar 22 The adhesive surface of the tip end side Ta of T is attached so as to have an appropriate winding angle (about 180 ° in this example) and wound or rewound (see FIGS. 7 and 9).

  In order to adjust the sticking force of the adhesive tape T on the outer peripheral surface, the holding rod 22 of this example forms an uneven portion that is dispersed by applying uneven processing such as a file on the outer peripheral surface, and is formed on the surface of the convex group. The adhesive surface of the adhesive tape T is stuck. The ratio of the surface area of the convex portion group per unit area of the outer peripheral surface of the holding rod 22 is appropriately selected depending on the adhesive force of the adhesive tape T, and is wound around the outer peripheral surface of the holding rod 22 so that the tip side Ta of the adhesive tape T is attached. The adhesive tape T does not peel off when moved (see FIG. 8), and the adhesive tape T peels off smoothly when the tip side Ta of the adhesive tape T is rewound from the outer peripheral surface of the holding rod 22 (see FIG. 9). A range is selected.

  In the present example, the contact / separation moving device 23 and the first moving / rewinding moving means 24 are guided by the first moving tool 27 and are movable in the left-right direction. A slider), a third moving tool 29 that pivotally supports the second moving tool 28 (slider) so as to swing up and down, and rotatably supports the holding rod 22, and a first moving tool 27 and a second moving tool 29.

The leading end side Ta of the adhesive tape T that is wound around and held is guided toward the tape tip delivery work position B. While the front end side Ta of the adhesive tape T is guided, the tape feeding device 4 is activated to feed the adhesive tape T toward the tape front end delivery work position B.

  Subsequently, after stopping the tape feeding device 4 and the reciprocating moving device 21 to stop the feeding and guiding of the adhesive tape T, the tape cutting device 6 is operated to cut the adhesive tape T to the set size. When the cutting is completed, the tape feeding device 4 and the reciprocating moving device 21 are activated again, and the leading end side Ta of the adhesive tape T is moved to the tape leading edge delivery work position B. Next, as shown in FIG. 9, the tape front end guiding device 5 holds the holding rod 22 in the standby state by operating the pressing / separating contact / separation moving device 23 at the tape front end delivery work position B. After moving toward the moving device 7 and pressing or approaching the tip side Ta of the adhesive tape T wound around the outer peripheral surface of the holding rod 22 on the tape holding surface 7a of the tape holding / moving device 7, the winding is performed. -The holding rod 22 is moved in the direction toward the tape front end Ta of the adhesive tape T (in this example, the direction toward the right) by the synchronized operation of the first moving means 24 for rewinding and the fifth moving device 35. By rotating in the rewinding direction (clockwise in this example), the front end side Ta of the adhesive tape T wound and held on the holding rod 22 is rewound from the outer peripheral surface of the holding rod 22.

  Finally, the tape front end guiding device 5 moves the holding rod 22 away from the tape holding / moving device 7 by operating the pressing / separating contact / separation moving device 23, and sucks and holds it on the tape holding surface 7a which is in a sucked state. The holding rod 22 is separated from the front end side Ta of the adhesive tape T thus applied, and the delivery of the front end side Ta of the adhesive tape T to the tape holding / moving device 7 is completed. As shown in FIG. 5, the tape tip guide device 5 that has been delivered returns the holding rod 22 to the first tape tip holding work position A by operating the reciprocating moving device 21. The tape holding / moving device 7 transfers the adhesive tape T that has been delivered and sucked and held by the tape holding surface 7a to a tape sticking work position that is separated as the operation arm 50 of a robot (not shown) moves. It conveys reliably and sticks the adhesive tape T to a target object.

  The device 1 of the present invention holds the front end Ta of the adhesive tape T in a state of being wound around and attached to the holding rod 22 and moves it together with the holding rod 22 from the tape tip holding work position A to the tape tip delivery work position B. By unwinding and delivering from the holding rod 22 at the tape tip delivery work position B, the tip side Ta of the adhesive tape T can be reliably pulled out to the tape tip delivery work position B. Since the tape T can be cut to a set dimension, it is possible to save labor without requiring a lot of conventional labor and skill.

  In addition, the device 1 of the present invention uses a rotary holding rod as the holding rod 22 so that the tip end side Ta of the adhesive tape T is held in a state of being wound around and attached to the holding rod 22 to hold the tape tip. Since it can be moved together with the holding rod 22 from the position A to the tape tip delivery work position B, unwound from the holding rod 22 and delivered to the tape holding surface 7a of the tape holding / moving device 7, the holding to the adhesive tape tip side Ta is possible. The rod 22 can be held and separated smoothly.

In this state, the holding rod 22 is moved in the left-right direction by operating the moving operation tool 93 and rotated in the forward / reverse direction so that the front end side Ta of the adhesive tape T is wound / rewinded on the outer peripheral surface of the holding rod 22. It is like that.
