The upper left arm 61A is shorter than the upper right arm 62A, and the left intermediate arm 61B. Is longer than the right middle arm 62B, and the lower left arm 61C is set to have the same length as the lower right arm 62C. Thereby, the displacement means 60 can move the suction plate 41 in the left-right direction including the rotation in the XZ plane so that the suction plate 41 can be in an inclined posture.

  The restricting means 64 biases the upper stopper 64A supported on the lower surface of the support plate 65, the lower stopper 64B supported on the upper surface of the suction plate 41, and the upper stopper 64A and the lower stopper 64B in the approaching direction. And a tension spring 64C as an urging means.

In the above sheet sticking apparatus 10, the procedure for sticking the adhesive sheet AS to the adherend WK will be described.
First, after the operator sets the original fabric RS as shown in FIG. 1, when an operation start signal is input via an input means (not shown) such as an operation panel or a personal computer, the feeding means 20 causes the rotation motor 23 and the illustration. Drive the drive device that does not, and feed out the raw fabric RS. Then, when a detection means (not shown) such as an optical sensor or an imaging means detects that the leading adhesive sheet AS positioned on the upper part of the peeling plate 30 has reached a predetermined position, the feeding means 20 drives the rotation motor 23 and a drive (not shown). Stop driving the device. Further, the pressing means 50 drives the linear motion motor 51 to position the suction plate 41 at the sheet receiving position P1 as shown by the solid line in FIG. 1, and the front end side in the feeding direction of the adhesive sheet AS on the suction plate 41 is the bond. The suction plate 41 is displaced so as to have an inclined posture closer to the adherend surface WK1 than the rear end side in the feeding direction of the sheet AS, that is, an inclined posture with respect to the line L1 parallel to the adherend surface WK1. The sticking device 10 enters a standby state. Note that, in this standby state, the rear end side of the adhesive sheet AS in the suction plate 41 in the feeding direction is upstream of the folded portion of the peeling sheet RL folded at the front end (left end) of the peeling plate 30. Located in the upper part.

  Next, when the conveying means 80 drives the conveyor or the like and conveys the adherend WK to a predetermined position below the pressing means 50 and stops as shown by the solid line in FIG. While being driven, the spraying means 70 starts spraying the gas, and the feeding means 20 drives the rotating motor 23 and a driving device (not shown) to feed out the original fabric RS. As a result, the leading adhesive sheet AS is peeled off by the peeling plate 30 and is sucked and held by the holding surface 41A, and the next adhesive sheet AS following the leading adhesive sheet AS has reached the upper predetermined position of the peeling plate 30. When the detection means (not shown) detects, the feeding means 20 stops driving the rotation motor 23 and the driving device (not shown). At this time, the adhesive sheet AS peeled off by the release plate 30 is bent following the folded release sheet RL by the adhesive force of the adhesive AD layer of itself, but its own rigidity is the adhesive strength of the adhesive AD layer. Since it is separated from the release sheet RL by overcoming, it is fed out toward the lower left. Further, the adhesive sheet AS peeled off by the peeling plate 30 tends to hang down because its own rigidity is lost to gravity. Therefore, by setting the suction plate 41 at the sheet receiving position P1 to the inclined posture, it is possible to prevent the suction sheet 41 from being sucked and held by the suction plate 41. In addition, the rear end side in the feeding direction of the adhesive sheet AS in the suction plate 41 is located above the folded portion of the peeling sheet RL folded at the tip of the peeling plate 30 and enters the upstream side in the feeding direction of the adhesive sheet AS. Therefore, the adhesive sheet AS peeled off from the release sheet RL can be held so as not to protrude from the rear end in the feeding direction of the adhesive sheet AS on the suction plate 41, and the pressing force by the pressing means 50 cannot be applied. Further, it is possible to prevent the rear end side in the feeding direction of the adhesive sheet AS attached to the adherend WK from being turned over, or air bubbles from being mixed into the rear end side.

  Thereafter, when the pressing means 50 drives the linear motion motor 51 and lowers the suction plate 41, the suction plate 41 is initially biased by the tension spring 64C, and the rolling roller 42 moves along the guide surface 63A. 2, and moves diagonally to the left. Next, as shown by a two-dot chain line in FIG. 2, when the upper stopper 64 </ b> A and the lower stopper 64 </ b> B come into contact, the suction plate 41 moves diagonally to the left. Then, the rolling roller 42 moves away from the guide surface 63A to the sheet sticking position P2, and presses the adhesive sheet AS against the adherend surface WK1 of the adherend WK as shown by the solid line in FIG. Affix it.

  When it is detected by a detection means (not shown) such as a pressure sensor or a load cell that a predetermined pressing force is applied to the adhesive sheet AS, the pressing means 50 drives the linear motion motor 51 to raise the suction plate 41. The suction plate 41 returns to the position indicated by the solid line in FIG. And the conveyance means 80 drives a conveyor etc., the to-be-adhered body WK with which adhesive sheet AS was stuck is conveyed to the following process, and the same operation | movement is repeated after that.

  According to the present embodiment as described above, since the suction plate 41 can be displaced in the biaxial direction only by the power of the single linear motor 51, the vertical direction intersecting the adherend surface WK1 and the vertical direction are While making it possible to move the suction plate 41 in different left and right directions, it is possible to prevent the apparatus from becoming large and the apparatus control from becoming complicated.
