  In FIG. 1 and FIG. 2, the sheet sticking apparatus 10 is provided in parallel with a conveying means CV including a belt conveyor or the like that conveys the adherend WK in the left-right direction. The sheet sticking device 10 is a feeding means for feeding out a raw fabric RS in which a belt-like sheet WS having an adhesive layer AD on one surface of a base material sheet BS is temporarily attached to the belt-like release sheet RL via the adhesive layer AD. 11, printing means 12 for performing desired printing on the belt-like sheet WS, a cut CU having a predetermined shape is formed on the belt-like sheet WS, and the inside of the cut CU is formed as an adhesive sheet AS. A notch forming means 14 for forming an unnecessary sheet US outside the cut-in CU, and a printing means 12 and the notch forming means 14 are disposed opposite to each other with the original fabric RS interposed therebetween. 14, a single pressure receiving means 15 that receives the pressing force applied from 14, a peeling plate 17 as a peeling means for peeling the adhesive sheet AS from the peeling sheet RL, and the adherend WK to the adherend WK. It is constituted by a pressing means 18 for affixing it pressed.

  The feeding means 11 includes a support shaft 20 that supports the raw fabric RS, a drive roller 21 and a pinch roller 22 that sandwich the unnecessary sheet US and the release sheet RL that have been fed from the support shaft 20 and passed through the release plate 17. A winding shaft 24 is provided that winds the unnecessary sheet US and the release sheet RL after passing through them with a predetermined torque by a driving device (not shown). The drive roller 21 is rotatably provided via a rotation motor DM1 as a drive device.

  The printing means 12 is disposed on the belt-like sheet WS side of the raw fabric RS to be fed, and is disposed above the pressure receiving means 15 with the raw fabric RS interposed therebetween, and an ink pan 26 containing ink, and a part of the outer peripheral surface of the ink. Is provided with an ink roller 27 disposed so as to be immersed, a transfer roller 28 in contact with the outer peripheral surface of the ink roller 27, and a plate cylinder 30 onto which the ink is transferred via the transfer roller 28. The plate cylinder 30 is provided with a printing plate for performing predetermined printing on the belt-like sheet WS, and ink is transferred from the transfer roller 28 to the printing plate. In the present embodiment, the ultraviolet curable ink is used.

  The notch forming means 14 is disposed on the belt-like sheet WS side of the raw fabric RS to be fed out, and is disposed on the left side of the pressure receiving means 15 with the raw fabric RS interposed therebetween. It is provided with a projecting closed loop-shaped cutting blade 33, and is provided so as to be able to form a substantially rectangular cut CU. A fixing means 35 is incorporated in the inner region of the cutting blade 33 in the die cut roller 32. The fixing unit 35 includes a plurality of LEDs (light emitting diodes) capable of emitting ultraviolet rays, and is provided on the outer peripheral surface of the die cut roller 32 at a predetermined interval. The LED may be provided in the same plane as the outer peripheral surface without jumping out from the outer peripheral surface of the die cut roller 32.

  The pressure receiving means 15 includes a rotation motor DM2 as a driving device, and an impression cylinder roller 16 provided rotatably via the rotation motor DM2. The plate cylinder 30 and the die cut roller 32 are rotatably provided in conjunction with the rotation of the plate cylinder 30 by a transmission mechanism (not shown).

  The pressing means 18 includes a suction plate 38 and an air cylinder 39 as a drive device that supports the suction plate 38 so as to be able to advance and retreat toward the adherend WK. The suction plate 38 includes a number of suction holes (not shown) on the lower surface side, and is configured to suck and hold the adhesive sheet AS from the upper surface side by suction means such as a suction pump and a vacuum ejector (not shown).

  Next, a method for applying the adhesive sheet AS in the present embodiment will be described.

  First, the original fabric RS supported by the support shaft 20 is passed between the impression cylinder roller 16 and the plate cylinder 30 and the die cut roller 32, and then folded at the tip of the peeling plate 17 to drive the roller 21 and the pinch roller 22. And the lead end is fixed to the take-up shaft 24.

  Then, the feeding means 11 and the pressure receiving means 15 drive the rotation motors DM <b> 1 and DM <b> 2 and feed the original fabric RS from the support shaft 20 toward the winding shaft 24. When the original fabric RS passes between the plate cylinder 30 and the impression cylinder roller 16, the printing unit 12 performs printing on the base sheet BS side of the belt-like sheet WS. After this printing, when the original fabric RS passes between the die-cut roller 32 and the impression cylinder roller 16, the cut forming means 14 surrounds a region where printing is performed from the base sheet BS side by the cutting blade 33. A shaped cut CU is formed. Thereby, the belt-like sheet WS is divided into an adhesive sheet AS inside the cut CU and an unnecessary sheet US outside the cut CU. In the printing on the belt-like sheet WS and the formation of the cut CU, the pressing force applied from the plate cylinder 30 and the die cut roller 32 is received by the single impression cylinder roller 16. Further, during the formation of the cut CU, the fixing means 35 emits light from the LED, and the ink is cured and fixed by irradiating the ink with the ultraviolet rays of the LED.

  After that, when the feeding means 11 and the pressure receiving means 15 drive the rotation motors DM1 and DM2 and continue to feed the original fabric RS, a plurality of printed adhesive sheets AS are formed. Then, when it is detected by a sensor (not shown) that the leading adhesive sheet AS has reached a predetermined position on the peeling plate 17, the feeding of the original fabric RS is temporarily stopped. Next, the adherend WK is transported by the transport means CV and stops at a predetermined position below the suction plate 38. When it is confirmed that the adherend WK has stopped, the feeding means 11 and the pressure receiving means 15 drive the rotation motors DM1 and DM2 to restart the feeding of the raw material RS, and the peeling sheet RL is released at the tip of the peeling plate 17. The adhesive sheet AS is peeled off. Then, the pressing means 18 drives a suction means (not shown) to suck and hold the adhesive sheet AS peeled off by the suction plate 38, and also drives the air cylinder 39 to move the suction plate 38 toward the upper surface of the adherend WK. Lower. Thereby, the adhesive sheet AS is affixed to the adherend WK.

  Therefore, according to such an embodiment, since the printing unit 12 and the notch forming unit 14 serve as the single impression cylinder roller 16, each of the printing unit 12 and the notch forming unit 14 has an impression cylinder. The number of parts can be reduced compared to the case where rollers are installed. In addition, since the feeding path from the printing unit 12 to the notch forming unit 14 can be shortened, the apparatus configuration can be simplified and the entire apparatus can be downsized. In addition, since both the printing unit 12 and the notch forming unit 14 are brought close to the impression cylinder roller 16 and the fixing unit 35 is incorporated in the die-cut roller 32, the configuration can be simplified and the entire apparatus can be reduced in size. Can do.
