Further, the control means 20 has a function of controlling the printing contents by the printing means 23 by the output of the barcode reader 47 that reads the barcode attached to the adherend W.

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

  When the first adherend W is transported by the adherend transport means 16, first, the barcode attached to the first adherend W is read by the barcode reader 47. The printing unit 23 is controlled by the control unit 20 based on the read bar code information, and predetermined printing is performed on the upper surface of the adhesive sheet S by the print head 30. The adhesive sheet S on which printing has been completed is peeled from the release sheet RL by the peel plate 24, and the peeled adhesive sheet S is transported by the belts 38 of the first to third transport units 33 to 35 and is transported to the third transport. It is detected by a sensor (not shown) provided in the unit 35 and stops at a predetermined position. Note that the adherend transport speed v of the adherend transport means 16 is input to the control means 20 in advance.

  When the first adherend W that has passed the bar code reader 47 is further conveyed, it is detected by the length detection means 19 and the line sensor 18, and the data is output to the control means 20 so that the adherend W A length Wl and a height Wh with respect to the transport direction are specified. Further, the bonding position of the adhesive sheet S in the transport direction with respect to the obtained length W1 of the adherend W is also obtained by the control means 20.

  Thereafter, the control unit 20 swings the second and third transport units 34 and 35 via the linear motor 45 in accordance with the height Wh of the adherend W, and the third transport that becomes the pressing unit 13. The part 35 is put on standby at a pressing preparation position for pressing the adhesive sheet S. The pressing preparation position is a height position at which the lowermost portion of the belt 38 in the third transport unit 35 is slightly separated from the adherend surface Ws.

  Then, when the adherend W is detected by the sensor P, the second and third transport units 34 and 35 are prepared for pressing after a predetermined time has elapsed so that the adhesive sheet S is stuck to a predetermined position of the adherend W. The belt 38 is lowered again from the position, and the belt 38 rotates in synchronization with the adherend W, so that the adhesive sheet S is stuck on the adherend W by being pressed by the third transport unit 35. As shown in FIG. 3A, the sensor P is a position where the lowermost portion of the position where the third transport unit 35 is closest to the adherend transport means 16 crosses, and the adherend transport means 16 Are provided on both sides in the short width direction.

The 3rd conveyance part 35 rotates with the circular-arc locus shown with the code | symbol R in the figure according to the detected height Wh of the to-be-adhered body W. As shown in FIG. At this time, the lowermost portion of the belt 38 changes the shift amount Ld toward the downstream side in the transport direction of the adherend W. The deviation amount Ld is obtained by the control means 20 by the calculation formula shown in FIG. 3A, for example, at the moment when the height Wh is measured by the line sensor 18 (Lt is the driving pulley 37D of the second transport unit 34). To the center of the driven pulley 37F of the third transport unit 35). Further, the distance at which the adhesive sheet S starts to be applied from the tip position of the adherend W at the moment when the length Wl is measured by the length detection means 19 is obtained by the calculation formula shown in FIG. Then, the time t for lowering the second and third transport units 34 and 35 after the tip of the adherend W is detected by the sensor P is determined from the transport speed v of the adherend transport means 16, for example, FIG. Obtained by the calculation formula shown in Then, the linear motion motor 45 is controlled by the control means 20 so that the adhesive sheet S is stuck to a desired position (a central position in the transport direction) of the adherend W, and the adhesive sheet S is pressed by the third transport unit 35. Affixed. Thereby, even if the height Wh of the adherend W changes, the adhesive sheet S can be applied with high accuracy to the obtained adhesion position in the transport direction of the adherend W. In addition, since the lowest part of the 3rd conveyance part 35 changes with rotation of the 2nd and 3rd conveyance parts 34 and 35, the control means 20 further detects the adhesive sheet S stopped by the sensor which is not shown in figure. The third conveyance unit 35 is controlled such that the sticking start end (left end in FIG. 3) of the adhesive sheet S is positioned at the lowermost part of the third conveyance unit 35 by feeding or returning.

  Prior to the application of the adhesive sheet S described above, the adherend transport means 16 passes the adherend W one after another, and the barcode attached to them is read by the barcode reader 47, and the adherend W The adhesive sheet S corresponding to is made in the second and first transport units 34 and 33 and stopped. Each time the adhesive sheet S is affixed, the third transport unit 35 is swung up and down as described above while the adhesive sheet S is sequentially transported to the third transport unit 35 side.

  Therefore, according to such an embodiment, even when the adhesive sheets S are sequentially attached to the adherends W having different heights, the third transport unit 35 is provided between the pressing standby positions of the adherends W. The adhesive sheet S can be stuck only by moving. This eliminates the need to reciprocate the pressing means 13 between the supply position of the adhesive sheet S and the adherend surface Ws each time the adhesive sheet S is applied, and the number of adhesive sheets S applied per unit time can be reduced. The increase can be achieved.
