The operation of the sheet sticking device EA1 provided with the above winding device EA will be described.
First, with respect to the sheet sticking device EA1 in which each member is arranged at the initial position shown in FIG. 1, the user of the sheet sticking device EA1 (hereinafter, simply referred to as “user”) attaches the adhesive sheet base material as shown in the figure. After setting AB, a signal for starting automatic operation is input via an operation panel (not shown) or an operation mechanism such as a personal computer. Next, when the user or a transfer means (not shown) such as an articulated robot or a belt conveyor places the adherend WK on the adherend support surface 62A at a predetermined position as shown in FIG. 1, the support means 60 drives a decompression means (not shown) and a linear motion motor 61 to start suction holding of the adherend WK on the adherend support surface 62A and raise the table 62. After that, the sticking means 50 drives the linear motor 56B and the linear motor 53, lowers the pressing roller 56D, presses the adhesive sheet base material AB against the sheet supporting surface 62B with a predetermined pressing force, and then two points in FIG. As shown by the chain line, the pressing roller 56D is moved to the right, and the adhesive sheet base material AB is pressed and attached to the adherend WK and the sheet support surface 62B.

Next, the sticking means 50 drives the articulated robot 31, the cutting blade 32 is held by the tip arm 31A, and the cutting blade 32 is pierced into the adhesive sheet base material AB as shown by the alternate long and short dash line in FIG. The cutting blade 32 is moved along the outer periphery of the adherend WK to form the adhesive sheet AS and the unnecessary sheet US. When the adhesive sheet AS and the unnecessary sheet US are formed, the sticking means 50 drives the articulated robot 31 to retract the cutting blade 32 to the rear of the supporting means 60. Then, the winding means 10 and the sticking means 50 drive the rotary motor 14A and the rotary motor 55A, and as shown by the alternate long and short dash line in FIG. 1, the frame 54 is moved to the right, and is unnecessary from the seat support surface 62B. The sheet US is peeled off and the unnecessary sheet US is wound up by the take-up shaft 13B. During this time, the winding means 10 drives the linear motor 11, and while pressing the winding shaft 13B against the drive roller 14 with a predetermined pressing force, the winding shaft 13B is adjusted to the outer diameter of the unnecessary sheet US wound around the winding shaft 13B. The winding member 13 after winding is moved up and down.
