[Operation of sheet pasting device]
Next, operation | movement of the sheet sticking apparatus 1 in this embodiment is demonstrated with reference to drawings.
First, when the original fabric RS is passed through the feeding means 10 and an automatic operation instruction is input, the feeding means 10 drives the rotation motor 15 to feed out the original fabric RS, and the first support means 21 is illustrated. The pressure reducing means and the rotation motor 21A are driven, the suction belt 21D is rotated at the same speed as the unrolled original RS, and the first first adhesive sheet AS1 peeled off by the peeling plate 14 is sucked and held to the left. To go out. Then, as shown by the solid line in FIG. 1, when the left end of the first adhesive sheet AS1 is detected at a predetermined position on the left side of the first support means 21 by a detection means (not shown) such as an imaging means or a photoelectric tube, the feeding means 10 and The first support means 21 stops driving the rotation motors 15 and 21A and enters a standby state. At this time, the second second adhesive sheet AS2 is stopped at a position sandwiched between the suction belt 21D and the release plate 14 on the right side of the first support means 21.

  When the adherend WK transported by the transport means CV such as a conveyor is detected by a detection means such as an imaging means or a photoelectric tube (not shown), the adherend WK is held by a two-dot chain line in FIG. It stops at a predetermined position below 30. Next, after the moving means 23 drives the linear motion motor 23C, the second support means 22 is raised, the rotating member 22C is brought into contact with the adhesive surface ASB of the first adhesive sheet AS1, and then the feeding means 10 and the first support are provided. The means 21 drives the rotation motors 15 and 21A to feed out the original fabric RS and to rotate the suction belt 21D at a constant speed with the fed-out raw material RS. Simultaneously with the driving of the rotation motors 15 and 21A, the moving means 23 drives the linear motion motor 23A to support the adhesive sheet AS from both the adhesive surface ASB side and the non-adhesive surface ASA side of the adhesive sheet AS. Carries both sides. At this time, the moving means 23 moves the second support means 22 to the left at a speed slightly faster than the speed at which the first adhesive sheet AS1 is conveyed by the suction belt 21D. Specifically, the moving means 23 is such that the overhang amount DA (for example, 40 mm) of the first adhesive sheet AS1 indicated by the solid line in FIG. 1 becomes the overhang amount DB (for example, 20 mm) indicated by the two-dot chain line in the same drawing. The direct acting motor 23A is driven so that a speed difference is generated. As described above, the first adhesive sheet AS1 is pulled by the rotating member 22C and the suction belt 21D even if the first adhesive sheet AS1 is in a wavy state due to the speed difference. It is conveyed to a predetermined position below the holding portion 31 while the undulating state is eliminated. Thereafter, when the left end of the second second adhesive sheet AS2 is detected by a detection means (not shown) at a predetermined position on the left side of the first support means 21, the feeding means 10 and the first support means 21 are turned to the rotation motor 15, The drive of 21A is stopped and it prepares for the next sticking.

  Thereafter, the first adhesive sheet AS1 that has slipped out from below the suction belt 21D is supported and transported only by the second support means 22, and when the first adhesive sheet AS1 is transported to a predetermined position below the holding surface 31A, an imaging (not shown) is performed. The moving means 23 stops driving the linear motion motor 23A. Next, the pressing unit 40 drives the linear motion motor 41 to bring the holding surface 31A of the holding unit 31 into contact with the non-adhesive surface ASA of the first adhesive sheet AS1, and then the holding unit 30 drives a decompression unit (not shown). The first adhesive sheet AS1 is sucked and held. Next, the moving means 23 drives the linear motion motors 23C and 23A to lower the second support means 22, and then retracts to the right. At this time, if the moving means 23 drives only the linear motion motor 23A without driving the linear motion motor 23C, and the second support means 22 is retracted to the right without lowering, the rotating member 22C is counteracted. Even if the first adhesive sheet AS1 is pressed and held by the holding surface 31A in a state where the first adhesive sheet AS1 undulates by rotating clockwise, the first adhesive sheet AS1 is pressed against the holding surface 31A. The 1-adhesive sheet AS1 is released from the state of being stretched and waved.

  Next, the pressing means 40 drives the linear motion motor 41, lowers the holding portion 31, and presses and sticks the first adhesive sheet AS1 to the upper surface of the adherend WK. Then, after a predetermined time has elapsed, after the pressing means 40 stops driving the decompression means (not shown), the linear motion motor 41 is driven to return the holding portion 31 to the upper initial position. The adherend WK to which the first adhesive sheet AS1 is affixed is conveyed by driving the conveying means CV, and thereafter the same operation is repeated.

According to this embodiment as described above, the following effects are obtained.
That is, by providing the conveying means 20 with the moving means 23 for moving the second support means 22 to a position facing the holding surface 31A of the holding means 30, the adhesive sheet AS is rubbed and waved on the holding surface 31A. The adhesive sheet AS can be stuck to the adherend WK without causing wrinkles.
