Thereby, as shown in FIG. 2B, the adhesive sheet AS <b> 1 peeled off by the peeling plate 23 is sucked and held by the first holding surface 32. And if the detection means (not shown) detects that the supply direction front-end | tip part of adhesive sheet AS2 reached | attained the predetermined position, the supply means 2 will stop the drive of the rotation motor 24 and the drive device not shown.

  Thereafter, the moving means 4 drives the linear motor 41 to move the suction plate 31 forward so that the second holding surface 33 is located at the supply position P1, as shown in FIG. Next, the holding unit 3 drives the second decompression unit 37, and the supply unit 2 drives the rotation motor 24 and a driving device (not shown) to feed out the original fabric RS. As a result, as shown in FIG. 2D, the adhesive sheet AS <b> 2 peeled off by the peeling plate 23 is sucked and held by the second holding surface 33. Then, when a detection unit (not shown) detects that the next adhesive sheet AS has reached a predetermined position, the supply unit 2 stops driving the rotation motor 24 and a driving device (not shown).

  Next, the moving means 4 drives the linear motor 42 to lower the suction plate 31 to the position indicated by the two-dot chain line in FIG. Thereafter, the holding means 3 stops driving the first decompression means 36, and the pressing means 5 drives the first gas supply means 51 to spray a predetermined amount of gas on the adhesive sheet AS1, and attach the adhesive sheet AS1. Affixed to the adherend surface WK1 of the body WK. After the gas is blown by the first gas supply means 51, the holding means 3 stops driving the second decompression means 37 after a predetermined time difference, and the pressing means 5 drives the second gas supply means 52, A predetermined amount of gas is blown onto the adhesive sheet AS2, and the adhesive sheet AS2 is pressed and attached to the adherend surface WK1 of the adherend WK.

And the conveyance means 6 drives, the to-be-adhered body WK with which several adhesive sheet AS1 and AS2 were affixed is conveyed to the following process, and the same operation | movement is repeated after that.

  According to the embodiment as described above, the diffused gas affects the adhesive sheet AS that has lost its support by providing a time difference to the plurality of held adhesive sheets AS1 and AS2 and blowing the gas. The adhesive sheets AS1 and AS2 can be prevented from being displaced in the surface direction of the adhesive sheet AS, and the plurality of adhesive sheets AS1 and AS2 can be attached to appropriate positions on the adherend WK without being displaced. Can be attached.

  As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the invention has been illustrated and described with particular reference to certain specific embodiments, but without departing from the spirit and scope of the invention, Various modifications can be made by those skilled in the art in terms of material, quantity, and other detailed configurations. In addition, the description of the shape, material, and the like disclosed above is exemplary for ease of understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded the limitation of one part or all of such restrictions is included in this invention.

For example, the moving means 4 is provided with a plurality of sliders 41 </ b> A that can move independently of each other on the linear motor 41, and each slider 41 </ b> A supports the linear motor 42, and is held by the output shaft 42 </ b> A of each linear motor 42. The means 3 and the pressing means 5 may be supported respectively.
Further, the moving means 4 does not employ the linear motion motor 42, but blows a predetermined amount of gas on the adhesive sheets AS1 and AS2 from the position where the adhesive sheet AS is sucked and held, thereby attaching the adhesive sheets AS1 and AS2 to the adherend. The structure which presses and sticks to the to-be-attached surface WK1 of WK may be sufficient.

  Further, a driving device that can relatively move the supply unit 2 and the holding unit 3 along the supply direction of the adhesive sheet AS is adopted, and the supply unit 2 and the holding unit 3 are held in accordance with the operation of peeling the adhesive sheet AS from the release sheet RL. The adhering sheet AS may be held on the suction plate 31 by relatively moving the means 3. In this case, only the supply unit 2 may move, only the holding unit 3 may move, or both the supply unit 2 and the holding unit 3 may move.

  The pressing means 5 is configured to further press the adhesive sheet AS with the first and second holding surfaces 32 and 33 after the adhesive sheet AS is pressed and pasted by blowing, or to cover the adhesive sheet AS by blowing. After pressing and adhering to the adherend surface WK1 of the adherend WK, it may be configured to be further pressed by a pressing roller, a blade material, or pressing auxiliary means such as rubber, resin, sponge, or the like.

Further, the number of the adhesive sheets AS held by the holding means 3 may be three or more, and the holding surface, the chamber, the pressure reducing means, and the gas supply means are each three according to the number of the adhesive sheets AS to be held. What is necessary is just to provide above.
