However, the one described in Patent Document 1 requires an air blow device, so that the device has become large in size. Further, it can be used only by the mount 72 provided with the ear piece 73, and there is a problem that the use is limited. The problem is that since the sandwiching member 75 simply moves up and down, the earpiece 73 of the mount 72 is sandwiched by folding it twice, so that the gripping member 75 has a wide grip in the front-rear direction like the earpiece 73. This is because it was necessary to provide a margin at the end of the mount 72.

Therefore, the present invention solves the above-mentioned problems and does not require an air blow device. Therefore, the device is compact and compact, and the sheet to which the seal is attached does not require an ear piece, so that various types of seals can be used. It is an object of the present invention to provide a peeling device that can be used and is not limited to applications.

In the seal peeling device of the present invention, a peeling treatment is applied to the upper surface, a sheet on which the seal is attached is placed, and a table that can slide along the main surface of the sheet and the seal are adsorbed. The holding member that holds the table in a releaseable manner, the first holding member that holds the rear end portion of the sheet along the slide direction of the table in a releaseable manner, and the front end portion of the sheet along the slide direction of the table are released. A second sandwiching member that can be sandwiched is provided, and the first sandwiching member sandwiches the rear end portion of the sheet, bends downward only once by rotating while sandwiching the sheet, and further moves downward. Thereby, the seal peeling device for peeling the seal held by the holding member from the sheet while sliding the table, and the second holding member bends the front end portion of the sheet upward. It is characterized by being pinched.

According to one embodiment of the present invention, the first sandwiching member sandwiches the rear end portion of the sheet, bends downward only once by rotating while sandwiching the sheet, and slides the table by moving further downward. The seal held by the holding member is peeled off from the sheet. Since the front end portion of the sheet is bent and sandwiched only once in this way, a wide width in the front-rear direction is not required for the gripping allowance of the sheet. It is not necessary to provide an ear piece on the sheet, and since the front end portion of the sheet can be widely sandwiched in the width direction instead of sandwiching only a local part such as an ear piece, no air blow is required. Since no air blow is required, the device can be made compact. Also, since the sheet does not require an ear piece, various types of stickers can be used.

The seal peeling device according to one embodiment of the present invention includes a table, a holding member, a first holding member, and a second holding member. The table is on which a sheet is placed and can be slid along the main surface of the sheet, and the sheet is peeled off on the upper surface and a sticker is attached to the upper surface. The holding member holds the seal so that it can be released by suction. The first sandwiching member releasably sandwiches the rear end portion of the sheet along the sliding direction of the table. The second sandwiching member releasably sandwiches the front end portion of the sheet along the sliding direction of the table. Then, the first holding member is The seal held by the holding member while sandwiching the rear end portion of the sheet, bending the sheet downward only once by rotating while sandwiching the sheet, and sliding the table further downward. Is peeled off from the sheet.

As shown in FIG. 1, the seal peeling device 1 of the present invention positions the table 4 on which the sheet 3 to which the seal 2 is attached and the sheet 3 formed on the upper surface of the table 4 are placed. A step portion 5 for the purpose and a guide 6 for surely inviting the sheet 3 to the step portion 5 are provided.

Further, as shown in FIG. 2, the first holding member 7 and the second holding member 8 are holding portions provided before and after the table 4.

The first holding member 7 includes a plurality of claws 9 having a convex shape on the upper claw 9a and a concave shape on the lower claw 9b that hold the end portion of the seat 3 so as to be able to release the holding, and a cylinder that drives the claw 9 up and down (FIG. (Not shown), the holding portion main body 10 having the claws 9 (see FIG. 1), the moving means for moving the holding portion main body 10 to a predetermined position in the horizontal direction (not shown), and the holding portion main body 10 are rotated. It is composed of a rotating means (air cylinder 11) to be made to move.

Then, the first holding member 7 is held at an arbitrary angle (about 90 degrees downward) while holding the rear end of the seat 3 by the claws 9 having a convex shape on the upper claw 9a and a concave shape on the lower claw 9b. The end face of the sheet 3 is firmly held by rotating to.

The second holding member 8 has the same configuration as the first holding member 7, and the difference is that the rotation angle of the rotating means 12 (see FIG. 4) is (upward about 90 degrees).

Further, the suction member 13 vacuum sucks the seal 2 attached on the sheet 3 and fixes (holds) it on the table 4.

As shown in FIGS. 4 and 5, the robot cylinder 14 moves the first holding member 7 diagonally downward (22 degrees in the illustrated example) at an arbitrary angle, and the force causes the table 4 to move horizontally toward the front end side. At the same time, the sheet 3 is also separated from the seal 2. After being separated, the table 4 moves to a fixed position by the urging force of the spring 15 (urging member).
Specifically, when the first holding member 7 holding the rear end of the seat 3 moves diagonally downward, the back surface of the seat 3 pushes the rear end side of the table 4 against the urging force of the spring 15. The table 4 moves horizontally to the front end side. Further, the first holding member 7 rotates downward while holding the rear end of the seat 3 (bends downward only once), and the second holding member 8 rotates upward while holding the front end of the seat 3. Therefore, the sheet 3 and the seal 2 can be easily peeled off, and the tension of the sheet 3 for horizontally moving the table 4 can be maintained above a certain level. By sandwiching the sheet 3 between the convex upper claw 9a and the concave lower claw 9b provided on the first sandwiching member 7 or the like, the tension can be reliably maintained above a certain level.
