The operation of the sheet sticking apparatus EA1 provided with the sheet manufacturing apparatus EA described above will be described.
First, a user of the sheet sticking device EA1 (hereinafter simply referred to as "user") places the original sheet RS on the sheet sticking device EA1 in which each member is arranged at the initial position indicated by the solid line in FIG. Set as shown, and input a signal for starting automatic operation through an operation means (not shown) such as an operation panel or a personal computer. Then, feeding means 10, sheet cutting means 20 and continuous unnecessary sheet peeling means 30 (hereinafter collectively referred to as "progressive feeding means") drive rotation motors 12A, 21 and 32A to rotate magnet roller 22. The cutting blade 23 is rotated to form a cut CU in the adhesive sheet base material AB, and the adhesive sheet base material AB is drawn out in the positive direction from the support roller 11 toward the recovery roller 13 . Then, when the magnet roller 22 rotates once, the forward feeding means stops driving the rotary motors 12A, 21, and 32A, and forms a cut CU having the same shape as the cutting blade 23 in the adhesive sheet base material AB (hereinafter referred to as forward feeding means). The above operation by the means is called "forward feeding operation"). Note that the entire adhesive sheet base material AB is peeled from the release sheet RL by the peel roller 31 until the leading end of the adhesive sheet AS formed by the cut CU passes the peel roller 31, but the leading end of the adhesive sheet AS After passing the separation roller 31 , the continuous unnecessary sheet US<b>1 formed by the cut CU is separated from the separation sheet RL by the separation roller 31 and collected by the continuous unnecessary sheet collection roller 33 .

Next, feeding means 10 and continuous unnecessary sheet peeling means 30 (hereinafter collectively referred to as “reverse feed means”) drive rotating motors 12A and 32A to move the sheet in reverse direction from collection roller 13 to support roller 11. After winding the adhesive sheet base material AB for a predetermined length in the direction, the rotation motors 12A and 32A are stopped (hereinafter, the above operation by the reverse feed means is referred to as "reverse feed operation"). After that, when the forward feeding means performs the forward feeding operation, as shown in FIG. The end region CU2 intersects, and a continuous cut CU is reliably formed. After that, the reverse feeding operation by the reverse feeding means and the forward feeding operation by the forward feeding means are repeated, and after several forward feeding operations, as shown in FIG. When the part is peeled off by the peeling edge 50A of the peeling plate 50 for a predetermined length, the next reverse feeding operation by the reverse feeding means is cancelled. As described above, when the leading edge of the leading adhesive sheet AS in the feeding direction is peeled off by the peeling edge 50A for a predetermined length, the other unnecessary sheets US2 are temporarily adhered to the peeling sheet RL, and are removed by the peeling roller. It is positioned in front of 44B.

Next, while the other unnecessary sheet peeling means 40 suppresses the driving of the rotating motor 41, the linear motion motor 44 is driven to move the peeling roller 44B as indicated by the chain double-dashed line on the right side of FIG. 1(C). While moving forward and pulling out the peeling tape PT from the side of the other unnecessary sheet collecting roller 46 against the application of a predetermined tension applied by the rotation motor 45, the peeling tape PT is pressed against the upper surface of the other unnecessary sheet US2. and affix it. When the peeling tape PT is attached to the front edge of the other unnecessary sheet US2, the unnecessary sheet peeling means 40 stops driving the direct-acting motor 44 and then suppresses the rotation of the rotation motor 41. In this state, the direct-acting motor 44 is driven again to move the peeling roller 44B toward the initial position. As a result, as indicated by the two-dot chain line on the left side in FIG. Other unnecessary sheet collecting rollers 46 collect the tape PT together with the tape PT. When the peeling roller 44B returns to the initial position, the other unnecessary sheet peeling means 40 stops driving the linear motion motor 44, drives the rotation motor 41, and peels the other unnecessary sheet US2 by a length longer than that which can be pasted next time. The tape PT is sent out toward the other unnecessary sheet collecting roller 46, and the driving of the rotation motor 41 is stopped.

Next, when a user or a conveying means (not shown) such as an articulated robot or a belt conveyor places the adherend WK on the adherend supporting table 72, the supporting means 70 drives the depressurizing means (not shown), and the support surface At 72A, suction holding of the adherend WK is started. Thereafter, the support means 70 drives the linear motor 71 to move the adherend support table 72 to the left, and when the adherend WK reaches a predetermined position, the reverse feed means performs a reverse feed operation. The forward feeding means performs a forward feeding operation in accordance with the moving speed of the adherend WK. 1A, the adhesive sheet AS is separated from the release sheet RL, and the adhesive sheet AS separated from the release sheet RL is applied to the adherend WK by the pressure roller 60. Pressed and applied. Next, when the leading edge of the next adhesive sheet AS following the first adhesive sheet AS is peeled off by the peeling edge 50A of the peeling plate 50 for a predetermined length, the forward feeding means stops the forward feeding operation. Also in this case, since the other unnecessary sheet US2 temporarily attached to the release sheet RL is positioned in front of the separation roller 44B, the other unnecessary sheet separating means 40 separates the other unnecessary sheet US2 from the release sheet RL in the same manner as described above. , the other unnecessary sheet US2 is collected by the other unnecessary sheet collecting roller 46 together with the peeling tape PT.

Then, when the entire adhesive sheet AS is attached to the adherend WK and the adherend support table 72 reaches a predetermined position on the left of the pressure roller 60, the support means 70 stops driving the linear motor 71. The depressurizing means is stopped, and the adherend WK held by the support surface 72A is released. Next, when the user or unillustrated conveying means conveys the adherend WK to which the adhesive sheet AS is attached to the next step, the support means 70 drives the linear motor 71 to move the adherend support table 72 to the initial position. After that, the operation similar to the above is repeated.
