For example, a cylindrical guide portion 120 can be adopted.

[Attachment process of protective film]
FIG. 13 is a diagram showing an example of a processing procedure of the protective film sticking process according to the first embodiment of the present technology. First, the film sticking portion 10 waits until the vehicle 9 is detected (step S101). This can be done by detecting whether or not the vehicle 9 has been transported to a predetermined detection position by a sensor or the like. When the vehicle 9 is detected (step S101: Yes), the film attaching portion 10 holds the seat 40 (step S102). Specifically, the elevating part 140 lowers the support part 130 and the sticking part 110 to the position of the sheet 40 supplied by the sheet supply part 30, and the suction cup 113 of the sticking part 110 sucks the sheet 40, so that the sheet 40 is released.

After the release paper (release paper 42) is peeled off, the protective film 41 is held in the sticking portion 110.

Next, the sticking portion 110 is moved to the position of the wheel 91 (step S104). This can be done by lowering the support portion 130 and rotating the support portion 130 by the elevating portion 140. As a result, the sticking portion 110 can be arranged so as to face substantially the same height as the wheel 91. Next, the transport unit 150 starts synchronous movement with the vehicle 9 (step S105). As a result, the sticking portion 110 moves in synchronization with the vehicle 9. Next, the support portion 130 moves the sticking portion 110 toward the wheel 91, and the guide portion 120 guides the sticking portion 110 to the position of the wheel 91 (step S106). Next, the sticking portion 110 sticks the protective film 41 according to the guidance of the guide portion 120 (step S107). This is executed by the support portion 130 pressing the sticking portion 110 and the protective film 41 held by the sticking portion 110 being pressed against the wheel 91. Note that step S106 is an example of the guidance procedure described in the claims. Step S107 is an example of the sticking procedure described in the claims.

After that, the synchronous movement of the transport unit 150 with the vehicle 9 is stopped (step S108), and the film sticking unit 10 returns to the standby position. After that, the process from step S101 is executed again. By the above procedure, the protective film 41 can be attached to the wheel 91 of the vehicle 9 conveyed by the conveyor 8. At this time, the protective film 41 can be attached without stopping the conveyor 8. Therefore, the protective film can be attached at high speed, and the conveyor 8 can be easily controlled. Further, since the sticking portion 110 moves in synchronization with the vehicle 9 at the time of sticking, the protective film can be accurately stuck to the position of the wheel 91.

As described above, the film sticking portion 10 of the first embodiment of the present technology moves the guide portion 120 and the sticking portion 110 in synchronization with the vehicle 9 to be conveyed, and responds to the guidance of the guide portion 120. The protective film 41 can be attached to the wheel 91. This makes it possible to simplify the process of attaching the protective film 41.

When sandwiching the edge of the paper pattern, a valley-shaped recess is formed at the edge of the paper pattern, and in the state where this recess is formed, the edge of the paper pattern is moved in the direction of peeling from the film to perform peeling. Will be done. The formed recesses are expected to improve the rigidity of the edge of the paper pattern.

In the second aspect of the present technology, the sandwiching portion may form the recessed portion starting from the vicinity of the boundary between the end portion of the release paper and the region to which the film is attached. The starting point of the recess is formed near the boundary, and it is expected that the initial peeling of the release paper will be formed near the boundary.

In the second aspect of the present technology, the sandwiching portion may be provided with a protruding portion on the surface forming the recess among the two surfaces that sandwich the edge of the release paper. It is expected that the protruding portion arranged in the sandwiching portion will form a valley-shaped recess at the end of the paper pattern.

In the second aspect of the present technology, the sandwiching portion may sandwich the release paper edge portion in a direction different from the direction parallel to the held film. The end of the release paper is sandwiched in a direction different from that of the release paper, and the end of the release paper bends in the vicinity of the boundary. It is expected to promote the formation of initial exfoliation.

In the second aspect of the present technology, a spraying portion for spraying gas may be further provided in the vicinity of the boundary between the edge of the release paper and the region to which the film is attached. It is expected that the release paper will be peeled off by the gas sprayed near the boundary.

In the second aspect of the present technology, the paper pattern may have a notch along the recess. The formation of recesses along the notch is expected.

According to such an aspect, the release paper release device according to the present technology has an excellent effect of simplifying the release step of the release paper attached to the protective film.

In the figure, a is a view showing the end portion 45 of the paper pattern seen from the side of the protective film 41. The alternate long and short dash line of a in the figure represents the sheet holding portion 111 of the sticking portion 110. Further, b in the figure is a cross-sectional view taken along the CC'line of a in the figure. The sheet holding portion 111 and the holding portion 23 constitute a paper pattern peeling device.

Since the protrusions 233 and the recesses 234 are arranged in the first sandwiching portion 231 and the second sandwiching portion 232, respectively, the sandwiched paper pattern end portion 45 has a valley-shaped recess when viewed from the side of the protective film 41. 48 is formed. Further, the starting point 49 of the recess 48 can be formed in the vicinity of the boundary 51 between the region where the protective film 41 is attached to the paper pattern 42 and the edge 45 of the paper pattern. The alternate long and short dash line of b in the figure represents the position of the side surface of the paper pattern 42 and the protective film 43 in the region other than the recess 48.

By forming the recess 48, the rigidity of the paper pattern end portion 45 can be improved. On the other hand, the protective film 41 is sucked by the suction cup 113 in the vicinity of the boundary 51, and relatively high rigidity is imparted in the region. Therefore, the paper pattern 42 is bent to a relatively large curvature in the vicinity of the boundary 51, which causes the initial peeling 52. When the holding portion 23 moves the release paper 42 in the direction of separating from the protective film 41 while sandwiching the release paper end portion 45, the release paper 42 is peeled off from the initial peeling 52, so that the release paper 42 can be easily peeled off. Can be done. Further, at this time, since the end portion 45 of the release paper has high rigidity, the tension due to the movement of the holding portion 23 can be concentrated in the vicinity of the boundary 51, and the release paper 42 can be peeled off more easily.

Further, as shown in b in the figure, the sandwiching portion 23 can sandwich the release paper end portion 45 in a direction different from the direction parallel to the protective film 41 held by the sticking portion 110. Specifically, the holding portion 23 can hold the release paper end portion 45 at an angle with respect to the protective film 41. As a result, the release paper 42 can be bent at the boundary 51, and the initial peeling 52 can be easily formed.

Further, the sheet 40 having the notch 47 described in d in FIG. 8 can also be applied to the above-mentioned release paper peeling device. At this time, the notch 47 is formed in the central portion of the paper pattern edge portion 45, and is arranged at a position along the recess 48. Therefore, the recess 48 can be easily formed by the holding portion 23.

[Other configurations of the paper pattern peeling device]
