Further, the adjusting tool 38 is provided with a slot hole 38B extending in an oblique direction (an oblique 45 degree direction) in FIG. 3 in the plane, and a set bolt 39 can be inserted into the slot hole 38B. The slot hole 38B is set to an extension length that allows two suction ports 31 adjacent in the oblique direction to be disposed inside. The set bolt 39 is provided so as to be able to be screwed to the suction port 31, whereby the positioning means 16 can be detachably attached to the suction port 31.

  Next, a method for applying the adhesive sheet S according to the present embodiment will be described.

  First, the shape of the adhesive sheet S and the feeding position of the adhesive sheet S fed from the feeding means 11 to the suction surface 29D are confirmed. Next, in order to mount the positioning means 16, the adjustment tool 38 is arranged so that the positioning end 38 </ b> A abuts on the left corner C forming edge of the adhesive sheet S arranged at the feeding position. Then, after inserting the set bolt 39 into the slot hole 38B, the set bolt 39 is screwed into the suction port 31 using a tool such as a screwdriver or a hexagon wrench. As shown in FIGS. 3A and 3B, the number of set bolts 39 for attaching one adjuster 38 may be one or two, or the length of the slot hole 38B or the pitch of the suction port 31. Depending on the case, it may be three or more. The position adjustment of the adjusting tool 38 can be performed with the set bolt 39 loosened. After the positioning means 16 is mounted, the bottom wall 29B is removed or opened from the side wall 29C, and all the suctions other than the suction port 31 which is located outside the adhesive sheet S arranged at the feeding position and where the set bolt 39 is mounted. After closing the mouth 31 with the closing means 33, the bottom wall 29B is attached or closed to the side wall 29C. Depending on the shape and size of the adhesive sheet S, the adjusting tool 38 may not be placed at the corner C of the adhesive sheet S. In such a case, the bottom wall 29A is subjected to a new female screw process and adjusted. The tool 38 may be disposed at the corner C of the adhesive sheet S.

  When the adherend W is transported by the transport means CV and is detected by a sensor (not shown) at a predetermined position, the rotation motor M is operated to feed the original fabric R by one pitch of the adhesive sheet S, and by the peeling plate 22. The adhesive sheet S is peeled from the release sheet RL. Thereby, the adhesive sheet S is fed out to the head part 29 side that stands by on the leading end side of the peeling plate 22 (a feeding step). Next, the adhesive sheet S fed to the head portion 29 side is sucked and held on the suction surface 29D from the base material sheet BS side by the suction port 31 communicated with the pressure reducing means via the pressure reducing pipe 32 (suction holding step). . In this suction holding step, the fed adhesive sheet S is positioned within the surface of the suction surface 29D with the corner C forming edge abutting against the positioning end 38A of the adjustment tool 38 (positioning step). When the adherend W reaches a position below the head portion 29, it is detected by a sensor (not shown) and the conveyance is stopped by a stopper (not shown).

  From this state, the air cylinder 35 is actuated so that the distance between the adherend W and the suction surface 29D becomes a predetermined distance (for example, the distance from the upper surface of the adherend W to the lower surface of the retaining bolt 39 is 10 mm). The head part 29 is lowered. Thereafter, the suction port 31 is communicated with the pressurizing means via the pressurization pipe 36 at the same time as the communication with the decompression means is interrupted. Thereby, gas is ejected from the opened suction port 31, and the adhesive sheet S is blown away by this ejection, and the adhesive sheet S is pressed against the adherend W and pressed (pressing step).

  Therefore, according to such an embodiment, since the positioning means 16 can be mounted using the suction port 31, the installation position of the positioning means 16 can be adjusted according to the location where the suction port 31 is formed. Moreover, since the slot hole 38B is formed in the adjustment tool 38, it is possible to give a width to the adjustment. Thereby, it becomes possible to cope with the change of the type of the adhesive sheet S to be attached without difficulty, and it is possible to suppress the preparation of a plurality of head portions 29 according to the type of the adhesive sheet S, and to replace the entire head portion 29. Can be eliminated.

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.

For example, the design of the positioning means 16 can be changed in various ways, and can be replaced with the configuration shown in FIG. 4A and 4B, the adjustment tool 42 is formed in a circular shape in plan view, and is mounted so that the adjustment tool 42 comes into contact with each end edge forming the corner C of the adhesive sheet S. A hole 42 </ b> A through which the set bolt 39 is inserted is formed in the surface of the adjustment tool 42. By setting the diameter of the hole 42A to be larger than the diameter of the shaft portion of the set bolt 39, the position of the adjusting tool 42 can be finely adjusted while the set bolt 39 is inserted. Further, by making the shape of the hole 42A a slot hole, it is possible to increase the amount of position adjustment in the extending direction.
The positioning means 16 shown in FIGS. 4C and 4D includes a bolt member 43 such as two hexagon socket head bolts, and each head edge of the bolt member 43 forms a corner C of the adhesive sheet S. Will come into contact.

  The pressing means 13 may be changed as long as the adhesive sheet S can be pressed against the adherend W and pasted. For example, the pressing means 13 may be configured by only the air cylinder 35, and the adhesive sheet S may be pressed against the adherend W by the lowering operation of the head portion 29 by the air cylinder 35 and pasted. At this time, in the above embodiment, the positioning means 16 protrudes downward from the lower surface of the adhesive sheet S. However, if the adherend W is a flexible material, damage to the adherend W can be avoided, In addition, when the adherend surface of the adherend W is the same size as the adhesive sheet S or fits in the adhesive sheet S, contact between the positioning means 16 and the adherend W can be avoided. In addition, when the press means 13 is comprised only with the air cylinder 35, the pressurization pipe | tube 36 and the pressurization pump (illustration omitted) connected to this can be abbreviate | omitted.

  Further, when the adhesive sheet S can be blown off from the feeding position at which the adhesive sheet S is fed from the feeding means 11 to the suction surface 29D and can be attached to the adherend W, the air cylinder 35 may be omitted in the pressing means 13. .

  Further, the closing means 33 may be mounted from the suction surface 29D side. Further, the mounting of the set bolt 39 can be performed from the upper surface side of the bottom wall 29 </ b> A by forming a female screw portion screwed into the set bolt 39 in the adjusting tool 38.

  The feeding means 11 can be variously modified as long as feeding can be performed as described above.

  Furthermore, the drive device in the embodiment includes an electric device such as a rotation motor, a linear motion motor, a linear motor, a single axis robot, and an articulated robot, an actuator such as an air cylinder, a hydraulic cylinder, a rodless cylinder, and a rotary cylinder. In addition to these, a combination of them directly or indirectly may be employed (some of them overlap with those exemplified in the embodiment).
