  However, in the conventional apparatus as described in Patent Document 1, since the blowing area of the gas in the width direction that intersects the supply direction of the adhesive sheet is constant, the adhesive sheet having a smaller width dimension than the blowing area or in the supply direction When affixing an adhesive sheet having different width dimensions depending on the position to the adherend, there is an inconvenience that energy is wasted because the spraying means is driven. That is, the operating rate of the gas supply means such as a pressure pump and a turbine must be increased so that gas can be sprayed over a wide area at all times in accordance with the adhesive sheet having a large width dimension. Thus, the energy for driving the spraying means is wasted. On the other hand, if the spray area is made small in order to eliminate the inconvenience, in the case of an adhesive sheet having a width dimension larger than that of the spray area, gas cannot be sprayed over the entire width direction of the adhesive sheet, so that no gas is sprayed. This causes another inconvenience that the adhesive sheet portion drips and the adhesive sheet falls without being adsorbed by the adsorption plate.

Yes.

The supply means 2 includes a support roller 21 that supports the original fabric RS, a plurality of guide rollers 22 that guide the original fabric RS, a release plate 23 that folds the release sheet RL and peels the adhesive sheet AS from the release sheet RL, A pinch roller 26 that sandwiches the release sheet RL between a drive roller 25 that is driven by a rotation motor 24 as a drive device, and a collection roller 27 that recovers the release sheet RL by a drive device (not shown).
The pressing means 4 includes a holding plate 42 that is supported by an output shaft 44 of a direct acting motor 43 as a driving device and has a holding surface 41 connected to a pressure reducing means (not shown) such as a pressure reducing pump or a vacuum ejector.

  As shown in FIGS. 1 and 2, the spraying means 5 is connected to a gas supply means 51 such as a pressurization pump or a turbine via a pipe 52 and changes the spraying area in the width direction of the adhesive sheet AS. Means 53 are provided. The spray area changing means 53 includes a solenoid valve 54 in which a plurality of spray holes 550 (first to fifth spray holes 551 to 555) are arranged in the width direction of the adhesive sheet AS, and dimensions in the width direction of the adhesive sheet AS. And an input means such as a personal computer or an operation panel (not shown) provided so as to be able to output the inputted width dimension information to the electromagnetic valve 54. The pressure of the gas in the pipe 52 is controlled to be a predetermined pressure by a detection means such as a pressure sensor (not shown).

In the sheet sticking apparatus 1 described above, a procedure for sticking the adhesive sheet AS to the adherend WK will be described.
First, when the operator sets the original fabric RS as shown in FIG. 1 and inputs a width dimension signal indicating the dimension in the width direction of the adhesive sheet AS and an operation start signal via an input means (not shown), It becomes a state. When the conveying means 7 conveys the adherend WK and reaches a predetermined position by a detecting means such as a sensor or a camera (not shown), the supplying means 2 drives the rotation motor 24 to The RS is fed out and the adhesive sheet AS is supplied along the holding surface 41 of the holding plate 42 from the peeling sheet RL at the peeling edge of the peeling plate 23.

  When the adhesive sheet AS begins to peel from the release sheet RL, the spraying means 5 drives the gas supply means 51 to supply the gas CG, and the spray area changing means 53 drives the electromagnetic valve 54 based on the width dimension signal. The valve of the electromagnetic valve 54 is opened so that the gas CG can be ejected from at least one of the first to fifth blowing holes 551 to 555 in accordance with the size in the width direction of the adhesive sheet AS. For example, when the adhesive sheet AS is a square and the dimension in the width direction is constant regardless of the position in the feeding direction, only from the first blowing hole 551 or from the first to third blowing holes 551 to 553, Or you may make it gas CG eject from the 1st-5th blowing holes 551-555. Thus, the operation rate of the gas supply means 51 changes with the quantity of the gas CG ejected from the spray hole 550. That is, the amount of gas supplied from the gas supply means 51 is controlled by a detection means (not shown), and when the gas CG is ejected from only the first blowing hole 551, the pressure drop rate of the gas in the pipe 52 is small. Therefore, the operating rate of the gas supply means 51 is low, and when the gas CG is ejected from the first to fifth blowing holes 551 to 555, the pressure drop rate of the gas in the pipe 52 is large. Occupancy rate becomes high. In addition, for example, when the adhesive sheet AS is a polygon or an irregular shape other than a circle or a rectangle, and the dimension in the width direction varies depending on the position in the feeding direction, the gas CG is selected depending on the length of the adhesive sheet AS fed out. You may change the combination of the 1st-5th spray holes 551-555 which eject. As a result, the gas CG can be sprayed over substantially the entire width direction of the adhesive sheet AS.

Next, the pressing unit 4 drives a decompression unit (not shown), and the holding plate 42 sucks and holds the adhesive sheet AS on the holding surface 41 as indicated by a two-dot chain line in FIG.
Thereafter, the pressing means 4 drives the linear motion motor 43 to lower the holding plate 42 and press the adhesive sheet AS against the adherend WK, as shown by a two-dot chain line in FIG. The driving of the means is stopped, and the suction of the holding plate 42 is stopped.
Next, the pressing means 4 drives the linear motor 43 to return the holding plate 42 to the position indicated by the solid line in FIG.
Thereafter, the conveying means 7 is driven to convey the adherend WK to which the adhesive sheet AS has been attached to the next step, and the new adherend WK is conveyed to a predetermined position below the pressing means 4 and stopped. Thereafter, the same operation is repeated.

  According to the embodiment as described above, by providing the spray region changing means 53, it is possible to spray the gas CG over a wide area as necessary, and the operating rate of the gas supply means 51 can be lowered.
