Description

  The present invention relates to a sheet sticking apparatus and a sticking method, and more specifically, in a state where a sheet is attached to an adhesive sheet, the sheet is sandwiched between the adhesive sheet and an adherend and attached. The present invention relates to a sheet sticking apparatus and a sticking method that can be used.

  Conventionally, a sheet pasting apparatus for pasting an adhesive sheet such as a delivery slip concealing confidential information on an adherend serving as a delivery product has been used. Such a sheet sticking device is disclosed in, for example, Patent Document 1. The sheet sticking apparatus of Patent Document 1 folds a single sheet on which confidential information is printed, and a single sheet folded by the folding means is bonded to the adhesive sheet, and then the adhesive sheet is covered. Pressing means for pressing and attaching to the body.

JP 2009-83402 A

  However, in Patent Document 1, since the sheet is folded and the printed content becomes invisible, after the sheet and the adhesive sheet are bonded, the printed content of the adhesive sheet is bonded to this. It becomes impossible to verify the printed content of a single sheet. Here, if the printed content of the sheet is imaged before the sheet is folded, the verification can be performed before bonding. There is a risk that the sheet may fall off and be lost. Also, after the verification of the printed contents, and before the pasting to the adhesive sheet, a problem occurs, and it is necessary to stop the device and remove the sheet or adhesive sheet to deal with the problem. There is also a possibility that the operator will set another sheet or adhesive sheet by mistake. For this reason, inconvenience that it becomes impossible to prove whether or not the printed contents of the adhesive sheet and the printed contents of the single-sheet are reliably aligned with each other is caused.

  Next, the overall operation of this embodiment will be described.

  When the adherend W to which a management label including printing information (not shown) is attached is conveyed by the conveyor C, the information on the management label is read by the third imaging unit 21. When this information is read, the motors M1 and M2 are driven, and the original fabrics R1 and R2 are fed out. And while the raw fabric R1 is being fed out, the first printing means 25 performs predetermined printing on the base sheet BS side of the adhesive sheet S1 based on the printing information of the management label. After this printing, the adhesive sheet S1 is peeled off from the release sheet RL by the release plate 28, sandwiched and transported between the round belt 46 and the guide roller 47, detected by the first detection means A1, and brought into a stopped state. At the same time, the original fabric R2 is subjected to predetermined printing on the upper surface of the belt-like sheet TS based on the printing information of the management label by the second printing means 37 during feeding. After this printing, the strip sheet TS is cut by the cutting means 39 to form the sheet S2. The sheet S2 is conveyed toward the bonding means 14 while being guided by the guide roller 53 and adsorbed from the printing surface side by the suction belt 52.

  When the single sheet S2 conveyed by the second conveying means 42 is detected by the second detecting means A2, the stopped round belt 46 is re-driven at a predetermined timing, and the adhesive sheet is synchronized with the suction belt 52. S1 is conveyed to the bonding means 14. After the sheet S2 is aligned so as to protrude to the right by the length L from the right end of the adhesive sheet S1, the press roller 43 presses the sheets S1 and S2 via the air cylinder 55, and the sheet S2 and adhesive sheet S1 are bonded together. At this time, since the width of the sheet S2 is smaller than the adhesive sheet S1, the non-printing surface of the sheet S2 is bonded so that the adhesive layer AD of the adhesive sheet S1 is partially exposed.

  The bonded adhesive sheet S1 and single sheet S2 are imaged by the first and second imaging means 19 and 20, and their consistency, relative position, print quality, print content, etc. are verified by the first verification means 22A. Is done. Further, from the respective imaging results of the first to third imaging means 19 to 21, the consistency of the printed contents of the sheets S1 and S2 and the adherend W is verified by the second verification means 22B. When the first and second verification means 22A and 22B determine that the verification is incompatible, the operation of the sheet sticking device 10 is stopped, a signal is output to a pilot lamp, a buzzer, etc. (not shown), and the operator is incompatible with the verification. Is to be announced.

  If the first and second verification means 22A and 22B determine that the verification is appropriate, the driving of the round belt 46 is stopped at the position where the right end of the adhesive sheet S1 is disposed on the right end of the contact body 65, and the holding means The adhesive sheet S1 is sucked and held by the suction pad 61 of 57. Next, as shown in FIG. 2, the contact body 65 is raised by the first air cylinder 66 of the pre-folding means 58, and the adhesive sheet S <b> 1 with the sheet S <b> 2 is sandwiched between the suction pad 61. Thereafter, the second air cylinder 67 is operated to lower the roller 68, whereby the sheet 68 is preliminarily bent at an angle of about 90 ° on the right side of the contact body 65 by the roller 68.

  After the sheet S2 is preliminarily folded, the suction pad 61 is moved to the right, and the sheet S2 is passed between the large diameter portions 70A of the stepped rollers 70. The roller 70 is rotated by driving of the motor M3 in synchronization with the movement of the suction pad 61 to the right side, and the adhesive sheet S1 and the sheet S2 are moved in the right direction while being folded with the printing surface of the sheet S2 as a mating surface. Pull out. At this time, since the length in the circumferential direction of the large diameter portion 70A is set not to exceed the protruding length L of the sheet S2, the end of the folded sheet S2 (the left end indicated by a two-dot chain line in FIG. 2) Part) can be adhered to the adhesive layer AD, and the roller 70 is prevented from adhering to the adhesive layer AD.

  After the sheet S2 is folded, the air cylinder 63 is operated to place the adhesive sheet S1 with the sheet S2 on the holder 75. Thereafter, the adhesive sheet S1 with the sheet S2 is transferred to the lower surface of the suction plate 77 via the single-axis robot 74, and then the suction plate 77 sucks and holds the adhesive sheet S1 and retracts the holding body 75 to the original position. Let Then, the suction plate 77 is lowered toward the adherend W by the operation of the cylinder 78, so that the folded sheet S <b> 2 is disposed between the adherend W and the sheet S <b> 2. It will be affixed on the adherend W by the adhesive layer AD of the adhesive sheet S1 that is exposed to the outside.

  Therefore, according to such an embodiment, the adhesive sheet S1 and the single sheet S2 are imaged after the adhesive sheet S1 and the single sheet S2 are bonded and before the single sheet S2 is folded. It becomes possible to improve the consistency of the adhesive sheet S1 and the sheet S2 that are simultaneously attached to the sheet. In addition, since the adherend W is also imaged and the correspondence with the sheets S1 and S2 is verified, the consistency between them can be improved.
