The release sheet RL is folded back at the release edge 23A, the release plate 23 as a release means for peeling the adhesive sheet AS from the release sheet RL, and the adhesive sheet AS is pressed against the ring frame RF and the adherend WK. Driven by a pressing roller 24 as a means and a rotation motor 25A as a driving device and sandwiching the release sheet RL between the pinch roller 25B and a driving device (not shown) between the pinch roller 25B A recovery roller 26 that always recovers the existing release sheet RL by applying a predetermined tension is provided.

The detecting means 30 includes a light emitting means 31 that emits electromagnetic waves such as ultraviolet rays, visible rays, infrared rays, gamma rays, and X-rays as light LE, a reflection means 32 that is provided in the support means 10 and reflects the light LE, and a reflection means 32. A light receiving means 33 for receiving the reflected light LE, provided at a position where it can be detected that the adhesive sheet AS is stuck at a predetermined position of the ring frame RF during the sticking operation of the sticking means 20, and the light emitting means 31. The light LE emitted from is reflected by the reflecting means 32, and the reflected light LE is received by the light receiving means 33, so that it is detected that the adhesive sheet AS is stuck at a predetermined position of the ring frame RF. ing.
In the case of the present embodiment, the detection means 30 is affixed to a predetermined position indicating that the front end AS1 and the rear end AS2 of the adhesive sheet AS in the adhesive sheet AS are affixed on the ring frame RF. It comes to judge.
The light emitting means 31 and the light receiving means 33 are integrated to form a photoelectric sensor 34.
The reflecting means 32 includes a first reflecting means 32A such as a mirror or a reflecting plate in which the first reflecting surface 32A1 is located between the left end of the opening RF1 of the ring frame RF on the support surface 12A and the left end of the recess 12B. A second reflecting means 32B such as a mirror or a reflecting plate is provided between the right end of the recess 12B on the support surface 12A and the right end of the opening RF1 of the ring frame RF.

In the above sheet sticking apparatus EA, the procedure for sticking the adhesive sheet AS to the ring frame RF and the adherend WK to form an integral object will be described.
First, a user (hereinafter simply referred to as “user”) of the sheet sticking device EA operates the sheet sticking device EA in a state indicated by a solid line in FIG. An automatic operation signal is input via an operating means (not shown) such as a panel or a personal computer. Then, the sticking means 20 drives the rotation motor 25A to feed out the original fabric RS, and the leading end of the leading adhesive sheet AS in the feeding direction is the peeling edge 23A of the peeling plate 23 as shown by the solid line in FIG. When the predetermined amount is peeled off, the drive of the rotation motor 25A is stopped.

  Next, a conveying means (not shown) such as a user or an articulated robot or a belt conveyor places the adherend WK at a predetermined position on the inner table 13, and the ring frame RF at a predetermined position on the outer table 12. , The support means 10 drives a decompression means (not shown), and starts holding the adherend WK and the ring frame RF on the support surfaces 13A and 12A. Then, the support means 10 drives the linear motor 11 to move the outer table 12 to the left, and when the outer table 12 reaches a predetermined position, the sticking means 20 drives the rotation motor 25A, and the outer table 12 The raw fabric RS is fed out in accordance with the moving speed. As a result, the adhesive sheet AS is peeled off from the release sheet RL by the release plate 23 and is pressed and stuck to the adherend WK and the ring frame RF by the pressing roller 24, so that the adherend WK passes through the adhesive sheet AS. Thus, an integrated object WK1 integrated with the ring frame RF is formed. Then, when the next adhesive sheet AS is peeled by a predetermined amount at the peeling edge 23A of the peeling plate 23, the sticking means 20 stops driving the rotation motor 25A.

  After that, when the outer table 12 reaches a predetermined position on the left side of the pressing roller 24, the support means 10 stops driving the linear motor 11, and then stops driving the decompression means (not shown), and supports the support surfaces 13A and 12A. The suction holding of the adherend WK and the ring frame RF is released. Next, when the user or a conveying means (not shown) conveys the integrated object WK1 to the next process, the supporting means 10 drives the linear motor 11 to return the outer table 12 to the initial position, and thereafter the same operation as described above is repeated. .

  Here, during the above-described pasting operation, the detecting means 30 drives the light emitting means 31 and the light receiving means 33, and the light receiving means 33 receives the light LE that is emitted from the light emitting means 31 and reflected by the reflecting means 32. Thus, it is determined whether or not the adhesive sheet AS has been attached to a predetermined position of the ring frame RF. In the case of the present embodiment, the detection unit 30 stores at least the light amount of the light LE reflected by the first and second reflection surfaces 32A1 and 32B1, and is reflected by the ring frame RF, the adhesive sheet AS, etc., and receives the light. The pass / fail judgment is performed based on the difference in the amount of light LE received by 33. That is, as shown in FIG. 1B, when the leading end AS1 of the adhesive sheet AS is stuck on the ring frame RF, the light receiving means 33 causes the light LE reflected by the ring frame RF or the adhesive sheet AS. Is received, and the light LE reflected by the first reflecting surface 32A1 is not received (the same applies to the rear end AS2 in the feeding direction of the adhesive sheet AS). Then, the detection means 30 makes a judgment of pasting success, and the pasting means 20 and the supporting means 10 continue the above pasting operation.

  On the other hand, as shown in FIG. 1C, if the leading end AS1 in the feeding direction of the adhesive sheet AS is not stuck on the ring frame RF, the light receiving means 33 receives the light LE reflected by the first reflecting surface 32A1. (The same applies to the rear end AS2 in the feeding direction of the adhesive sheet AS). Then, the detection means 30 determines that the application has failed, the support means 10 stops the drive of the linear motor 11, stops the movement of the outer table 12 to the left, and the application means 20 turns the rotation motor 25A. Is stopped, and the feeding of the adhesive sheet AS is stopped (hereinafter also referred to as “pasting stop process”). Next, after a removal means (not shown) such as a user or an articulated robot or a blade removes the adhesive sheet AS determined to be unacceptable from the release sheet RL, the ring frame RF or the adherend WK, the support means 10 The linear motor 11 is driven to return the support means 10 to the initial position. Thereafter, the sticking means 20 drives the rotation motor 25A to feed out the raw fabric RS, and when the leading end portion of the next adhesive sheet AS in the feeding direction is peeled by a predetermined amount at the peeling edge 23A of the peeling plate 23, the turning motor 25A. Stop driving. Next, the support means 10 drives the linear motor 11, moves the outer table 12 to the left, and performs the pasting operation similar to the above.

  According to the embodiment as described above, since the detection unit 30 detects that the adhesive sheet AS has been applied to a predetermined position of the ring frame RF during the application operation of the application unit 20, it takes time until the detection. It can suppress that and the sheet sticking capability which sticks adhesive sheet AS per unit time can suppress that it falls.
