In this embodiment, the moving means 40 supports the bracket BR to which the cutting blade CM is attached with the tip arm 41A, moves the cutting blade CM with respect to the stationary sheet supporting means 10, and moves the cutting blade CM to the adhesive sheet base. The adhesive sheet AS is formed by cutting the material AB.

The operation of the sheet pasting device EA1 employing the above-described sheet supporting device EA will be described.
First, a user (hereinafter simply referred to as "user") of the sheet applicator EA1 (hereinafter simply referred to as "user") sets the sheet applicator EA1 in which each member is placed at the initial position shown by the solid line in FIG. 1(A) as shown in the figure. After setting the original fabric RS, a signal to start automatic operation is inputted via an operation means (not shown) such as an operation panel or a personal computer. Then, the sheet pasting means 30 drives the rotary motor 35A to feed out the original fabric RS, and as shown by the solid line in FIG. When the peeling edge 33A peels off a predetermined length, the rotation motor 35A stops driving.

Next, when a user or a conveyance means (not shown) such as an articulated robot or a belt conveyor places the adherend WK on the inner support surface 12A as shown in FIG. Then, the pressure reducing means that does not move is driven, and suction and holding of the adherend WK on the inner support surface 12A is started. Thereafter, the sheet support means 10 drives the linear motor 11 to move the support table 12 to the left, and when the support table 12 reaches a predetermined position, the sheet pasting means 30 drives the rotary motor 35A to move the support table 12 to the left. The raw fabric RS is fed out in accordance with the moving speed of the support table 12. As a result, the adhesive sheet base material AB is peeled off from the release sheet RL, and the adhesive sheet base material AB peeled off from the release sheet RL is moved by the pressure roller 34 as shown by the two-dot chain line in FIG. 1(A). It is pressed and attached to the outer support surface 12C and the upper surface of the adherend WK. Next, when the leading end in the feeding direction of the next adhesive sheet base material AB following the first adhesive sheet base material AB is peeled off for a predetermined length by the peeling edge 33A of the peeling plate 33, the sheet pasting means 30 is activated by the rotating motor. 35A is stopped.

Then, when the entire adhesive sheet base material AB is attached to the outer support surface 12C and the adherend WK and the support table 12 reaches within the working range of the moving means 40, the sheet supporting means 10 stops driving the linear motor 11. . Next, the moving means 40 drives the articulated robot 41, and as shown by the solid line in FIG. The cutting blade CM is pierced into the adhesive sheet base material AB so as to be further away from the inner support surface 12A than the contact surface 21A1. Thereafter, the moving means 40 drives the articulated robot 41 to move the cutting blade CM along the first contact surface 21A1 while bringing the cutting blade CM closer to the first contact surface 21A1. Next, as shown by the solid line in FIG. 1(C), when the contact detection means 22 detects that the cutting blade CM has contacted the first contact surface 21A1, the moving means 40 detects this contact position. Using the starting point, the cutting blade CM is made to make one revolution along the first abutting surface 21A1 while keeping it in contact with the first abutting surface 21A1. Then, an adhesive sheet AS is formed from the adhesive sheet base material AB, and an integrated object UP is formed in which the adhesive sheet AS is attached to the adherend WK. At this time, the first contact surface 21A1 assists the movement of the cutting blade CM, such as the moving direction and orientation, of the cutting blade CM moved by the articulated robot 41, thereby controlling the behavior, posture, etc. of the cutting blade CM. It is possible to stabilize the outer edge of the formed adhesive sheet AS.

When the integral object UP is formed, the moving means 40 drives the articulated robot 41 to return the cutting blade CM to the initial position. Then, when the sheet support means 10 stops driving the pressure reducing means (not shown) and releases the adsorption and holding of the adherend WK on the inner support surface 12A, the user or the conveyance means (not shown) moves the integrated object UP to the inner support surface. It is removed from 12A and the integrated object UP is transported to the next process. Next, when the user or a sheet peeling means (not shown) peels off the adhesive sheet base material AB from which the adhesive sheet AS has been cut out from the outer support surface 12C and discards it, the sheet support means 10 drives the linear motor 11 to remove the support. The table 12 is returned to its initial position, and the same operations as described above are repeated thereafter.

Here, when changing the size or shape of the adhesive sheet AS, the moving means 40 drives the articulated robot 41 to penetrate the adhesive sheet base material AB as shown by the two-dot chain line in FIG. 1(B). The cutting blade CM is pierced into the adhesive sheet base material AB such that the penetrating portion CM1 of the cutting blade CM is further away from the inner support surface 12A than the second contact surface 21A2 within the groove 12B. Thereafter, the moving means 40 drives the articulated robot 41 to bring the cutting blade CM into contact with the second contact surface 21A2, as shown by the two-dot chain line in FIG. Form AS.

According to the embodiment described above, since the penetrating portion CM1 is brought into contact with the contact portion 21 corresponding to the shapes of the plurality of types of adhesive sheets AS, while assisting the movement of the cutting blade CM, the shape of the plurality of types of adhesive sheets AS is An adhesive sheet AS can be formed.
