The suction holes 31 formed in the suction surface 32 include a plurality of Y axis rows (first to sixth Y axis rows Y1 to Y6) along the Y axis direction and a plurality of X axis rows (first to first axes) along the X axis direction. It is formed at the intersection of the sixth X axis rows X1 to X6).

  The suction region changing means 6 includes a predetermined number (one in the case of this embodiment) of suction holes 31 as one unit, and a plurality of (36 in the case of this embodiment) communication paths 60 provided for each unit. , A decompression case 62 having an opening 61 in the front, an insertion / extraction plate 64 as a main body portion provided with a through hole 63, which can be inserted into / removed from the opening 61 into the decompression case 62, and can be inserted into and removed from the through hole 63 And a countersunk screw 65 serving as a communication passage opening / closing means provided in the housing. In the decompression case 62, when the insertion / extraction plate 64 is inserted, a recess 66 (see FIG. 3) is formed above the insertion / extraction plate 64 and forms a decompression space SP communicating with the decompression source 41 via the pipe. ), And a plurality of communication holes 67 connected to the through-holes 63 and connected to the communication path 60 are provided below the insertion / extraction plate 64. Further, the through hole 63 formed in the insertion / extraction plate 64 is constituted by a female screw part 63A and a countersunk part 63B continuous to the female screw part 63A, and the communication passage 60 is individually decompressed by screwing the countersunk screw 65. 4, that is, the communication path 60 can be individually communicated with the decompression means 4, or the communication can be individually blocked. With such a configuration, each suction hole 31 communicates with the decompression source 41 via the communication path 60, the communication hole 67, the through hole 63, the decompression space SP, and the pipe 42, and the screw of the countersunk screw 65. Accordingly, communication with the decompression source 41 is interrupted, and the suction area can be changed.

The communication path 60 may be formed of a member that can be elastically deformed, such as resin or rubber, or may be formed of a member that cannot be elastically deformed. You may provide a flexible joint, a flexible tube, etc. so that it may not be influenced by the raising / lowering of the board 33. FIG.
In addition, at least one of the decompression case 62 and the insertion / extraction plate 64 prevents the outside air or the decompression from leaking from the opening 61 when the insertion / extraction plate 64 is inserted into the decompression case 62, and the decompression space SP A sealing means such as a packing or a shielding plate (not shown) is provided so that the suction holes 31 do not communicate with each other at the lower part of the insertion / extraction plate 64 so that the reduced pressure does not leak below the insertion / extraction plate 64.
Further, the interval between the through holes 63 may be wider or narrower than the interval between the suction holes 31. In particular, when the interval between the suction holes 31 is narrow, the interval between the through holes 63 is preferably set so that the operator does not need to attach and detach the countersunk screws 65 in a narrow space. In this case, the countersunk screw 65 can also be made large, and the inconvenience that the operator is forced to perform fine work can be solved. Further, since the suction area changing means 6 can be provided at a position separated from the holding means 3, it is possible to eliminate the inconvenience of putting a hand inside a narrow apparatus and forcing work.

In the sheet sticking apparatus 1 described above, a procedure for sticking the adhesive sheet AS to the adherend WK will be described.
First, the original fabric RS is set as shown in FIG. 1 while adjusting the rear edge of the adhesive sheet AS to a predetermined reference position. Next, a countersunk screw 65 is screwed into the through-hole 63 of the insertion / extraction plate 64, and the insertion / extraction plate 64 is inserted and accommodated in the decompression case 62 from the opening 61, so that the suction area on the suction surface 32 is the size of the adhesive sheet AS. Change to match. For example, when the adhesive sheet AS is an adhesive sheet AS1 having a size indicated by a solid line in FIG. 1, when the adhesive sheet AS1 is supported by the suction surface 32, a suction force is applied to the suction holes 31 located outside the adhesive sheet AS1. In order to prevent this, the suction hole 31 to which a suction force is applied is selected from the plurality of suction holes 31 and the suction region is changed. That is, as shown in FIG. 2, only the suction hole 31 at the intersection of the first to fourth Y-axis rows Y1 to Y4 and the first to second X-axis rows X1 to X2 communicates with the vacuum source 41, and the area is sucked. The through hole 63 corresponding to the other suction hole 31 is closed with a countersunk screw 65 so as to be an area. On the other hand, when the adhesive sheet AS is an adhesive sheet AS2 having a size indicated by a two-dot chain line in FIG. 1, the suction holes 31 at the intersections of the first to sixth Y axis rows Y1 to Y6 and the first to sixth X axis rows X1 to X6. The (all suction holes 31) are in communication with the vacuum source 41, and the region is a suction region.

  Next, when the adherend WK is transported on a transport means CV such as a conveyor, it is detected by a sensor (not shown), and the adherend WK is sucked by the suction plate 33 as indicated by a two-dot chain line in FIG. Stop at a position below the area. When it is confirmed that the adherend WK has stopped, the feeding means 2 drives the rotation motor DM and feeds the adhesive sheet AS, and the decompression means 4 drives the decompression source 41 and feeds the adhesive sheet. The AS is sucked and held in the suction area. When the adhesive sheet AS is sucked and held in the suction area, the sticking means 5 drives the linear motion motor 51 to lower the suction plate 33 toward the adherend WK, so that the adhesive sheet AS contacts the adherend WK. Let it stick.

  When the application of the adhesive sheet AS is completed, the decompression unit 4 stops the decompression source 41 and releases the adsorption and holding of the adhesive sheet AS by the adsorption plate 33, and then the application unit 5 drives the linear motion motor 51 to 33 is returned to the position indicated by the solid line in FIG. 3, and the same operation is repeated thereafter.

According to this embodiment as described above, the following effects are obtained.
That is, a plurality of communication paths 60 are provided, and the plurality of communication paths 60 are individually provided with the countersunk means 65 and the countersunk screws 65 that can be intermittently connected, so that the parts for changing the suction region can be changed in shape and size of the adhesive sheet AS. It is not necessary to prepare for each case, and versatility can be improved.
In addition, since the suction area can be changed simply by intermittently connecting and disconnecting the communication path 60 to and from the decompression means 4, the work burden on the operator can be reduced.

May be provided in the first X axis row X1, and the suction region may be changed by inserting and removing the countersunk screws 65 into the through holes 63 so that one suction hole 31 can be connected to the decompression means 4. In short, it is only necessary that the adhesive sheet AS can be sucked and held by the suction surface 32 regardless of the position, shape, and size of the adhesive sheet AS, and the suction holes 31 are provided in two directions different from the X-axis direction and the Y-axis direction. Also good.
