Description

The present invention relates to a sheet peeling device and a sheet peeling method.

A sheet peeling device is known in which a peeling tape is attached to an adhesive sheet attached to an adherend and tension is applied to the peeling tape to peel the adhesive sheet from the adherend (for example, Patent Document 1). reference).

JP-A-2017-50364

In the sheet peeling device 10 (sheet peeling device) described in Patent Document 1, the suction means 23F (holding member) presses the peeling tape PT (peeling tape) against the adhesive sheet AS (adhesive sheet) to attach it. Since the release tape is held at a position between the pressing head 25C (pressing member) and the cutting blade 72 (cutting member) for cutting the release tape, the distance between the pressing means and the cutting means is widened. For this reason, the length from the tip end portion of the release tape in the feeding direction to the attachment portion attached to the adherend becomes long, which causes the inconvenience of wasting the release tape.

An object of the present invention is to provide a sheet peeling device and a sheet peeling method capable of preventing wasteful consumption of the peeling tape.

The present invention has adopted the configuration described in the claims.

According to the present invention, since the holding member holds the peeling tape at a position other than between the pressing member and the cutting member, the distance between the pressing member and the cutting member is not widened, and the tape is attached from the tip of the peeling tape. Since the length to the portion is shortened, it is possible to prevent wasteful consumption of the peeling tape.
Further, if the holding member is juxtaposed with the pressing member in the intersecting direction intersecting the feeding direction of the peeling tape, the peeling tape held by the holding member can be reliably pressed by the pressing member.

The operation of the above sheet peeling device EA will be described.
First, with respect to the sheet peeling device EA in which each member is arranged at the initial position shown by the solid line in FIG. 1, the user of the sheet peeling device EA (hereinafter, simply referred to as “user”) is used for peeling as shown in the figure. After setting the tape PT and positioning the tip PT1 in the feeding direction of the peeling tape PT and the sticking portion PT2 to be stuck to the adherend WK at predetermined positions, an input means such as an operation panel or a personal computer (not shown) is used. The signal for starting automatic operation is input via. Then, the holding means 10 drives the suction means 17, and the suction means 17 starts sucking and holding the peeling tape PT.

Next, the user or a transport means (not shown) such as an articulated robot or a belt conveyor places the adherend WK to which the adhesive sheet AS is attached at a predetermined position on the support surface 52A as shown by the solid line in FIG. When mounted, the support means 50 drives a decompression means (not shown) to start adsorbing and holding the adherend WK on the support surface 52A. After that, the support means 50 drives the linear motor 51 to move the table 52 to the left, and when the left end portion of the adhesive sheet AS is located directly below the pressing member 22 as shown by the alternate long and short dash line in FIG. , The drive of the linear motor 51 is stopped. Next, the holding means 10 drives the linear motion motor 18, and as shown by the alternate long and short dash line in FIG. 1, the auxiliary roller 19 is retracted from below the accommodating means 16, and then the rotary motor 12 and the linear motion motor 15 The accommodating means 16 is lowered to a predetermined position directly above the adhesive sheet AS while feeding out the peeling tape PT. Then, the pressing means 20 drives the heating means 23 and the linear motor 21 to lower the heated pressing member 22, and as shown in FIG. 2 (A), the peeling tape PT held by the holding means 10 is attached. The portion PT2 is pressed and attached to the left end portion of the adhesive sheet AS attached to the adherend WK.

When the attachment of the peeling tape PT to the adhesive sheet AS is completed, the holding means 10 stops driving the suction means 17, the pressing means 20 drives the linear motor 21, and the holding means 10 drives the linear motor 15. It is driven to return the pressing member 22 and the accommodating means 16 to the initial positions. Next, the peeling means 30 drives the linear motion motor 34, and the peeling tape PT is sandwiched between the pinch roller 35 and the pressing roller 33 with a predetermined pressing pressure. After that, the support means 50 drives the linear motor 51, moves the table 52 to the left as shown in FIG. 2 (B), presses the left end of the adhesive sheet AS, and is positioned directly below the lowermost portion of the roller 33. Let me. Next, the holding means 10 drives the rotary motor 12, winds up the peeling tape PT by a predetermined length, drives the linear motor 31, and presses the stripping tape PT as shown by the chain double-dashed line in FIG. 2 (B). While bending the peeling tape PT at the lowermost part of the roller 33, the bent portion is pressed. Then, the peeling means 30 and the supporting means 50 drive the rotary motor 32 and the linear motors 36 and 51, and as shown by the solid line in FIG. 2C, the pressing roller 33 moves the table 52 to the left. Is rotated counterclockwise, and the guide roller 37 is moved to the right to apply tension to the peeling tape PT. As a result, the adhesive sheet AS is peeled off from the adherend WK while being pressed by the lowermost portion of the pressing roller 33 following the peeling tape PT, and is guided to the right by the guiding roller 37.

As shown by the alternate long and short dash line in FIG. 2C, when the entire adhesive sheet AS is peeled from the adherend WK, the peeling means 30 and the supporting means 50 drive the rotary motor 32 and the linear motors 36 and 51. Stop. Next, the holding means 10 drives the linear motion motor 18 to return the auxiliary roller 19 to the initial position, and then drives the suction means 17 to start sucking and holding the peeling tape PT by the suction means 17. After that, the cutting means 40 drives the linear motor 41, lowers the cutting blade 42 as shown in FIG. 2D, cuts the peeling tape PT from which the adhesive sheet AS has been peeled off, and newly replaces the peeling tape PT. Form a tip PT1. The adhesive sheet AS is collected by dropping into a collection means (not shown) such as a box or a bag due to its own weight. Next, when the user or a transport means (not shown) transports the adherend WK on the table 52 to the next step, each means drives each drive device to return each member to the initial position, and the same operation thereafter. Is repeated.

According to the above embodiment, since the suction means 17 holds the peeling tape PT at a position other than between the pressing member 22 and the cutting blade 42, if the distance between the pressing member 22 and the cutting blade 42 is wide. However, since the length from the tip portion PT1 of the peeling tape PT to the sticking portion PT2 is shortened, it is possible to prevent the peeling tape PT from being wasted.
