Therefore, detailed description thereof will be omitted.

  Next, the operation of the sheet sticking device 10 in this embodiment will be described. Each of the rollers 12 and 14 to 19 is configured so that the other end side is supported in substantially the same form via the holder 22. Therefore, the position adjustment method of these rollers is driven for convenience of explanation. The roller 14 will be described, and a duplicate description will be avoided.

  The sheet sticking device 10 is supported via a frame (not shown). When the original fabric R is wound around the sheet sticking device 10, the handle 30 is grasped and released. In this state, the roll-shaped raw fabric R is supported by the support roller 12, the lead end is pulled out, the guide rollers 17 and 18, the peel plate 13 and the guide roller 19 are passed between the drive roller 14 and the pinch roller 15.

Is done.

  The label L is affixed by rotating the driving roller 14 by driving the motor M and applying a repetitive output to the release sheet RL sandwiched between the driving roller 14 and the pinch roller 15. By this feeding, the label L is peeled off from the release sheet RL at the tip of the peel plate 13, and is attached to the adherend W which is transported along the transport means CV located below the sheet sticking apparatus 10 via the press roller PR. Will be.

  In the sheet sticking apparatus 10 of the present invention, the label L feeding test is performed before the label L is stuck on the adherend W. When it is determined in this test that the original fabric R is meandering, correction is performed by adjusting the position of the holder 22 that supports the central shaft 37 of the drive roller 14. That is, by loosening the eight bolts 68 and 73 and continuously feeding the label L, the Z-axis moving member 64 and the X-axis moving member 65 are moved to appropriate positions, whereby the rotational axis of the drive roller 14 is rotated. Is adjusted. Then, the bolts 68 and 73 are tightened at a position where it is confirmed that the original fabric R has no meandering, and the correction is completed. The Z-axis moving member 64 and the X-axis moving member 65 can be moved while confirming that the tip of the conical member 40 is not displaced from the center C through the light transmission window 55. .

  When the position adjustment of the driving roller 14 is completed, the sheet sticking apparatus 10 is automatically operated and the cover 23 is opened and closed as necessary. However, the rotational axis of the driving roller 14 is corrected as described above when the cover 23 is closed. Therefore, the label L can be accurately attached to the adherend. In addition, when the raw fabric R is changed to a type having a different width or a part of the soft member 43 is worn out with time, these may cause meandering and misfeeding. You can eliminate them by doing.

  Further, when it is necessary to adjust the positions of rollers other than the driving roller 14, the corresponding holder 22 may be adjusted as described above.

  Therefore, according to such an embodiment, by supporting the rotational axes of the rollers 12 and 14 to 19 on both sides, the rotational axes are stabilized, so that the label L can be fed out at a high speed. In addition, even if meandering or misfeeding occurs when unwinding the raw fabric R, it is eliminated without difficulty by adjusting the rotation axis of the roller from the outside of the cover 23 without removing or disassembling the roller. The effect that it can be obtained.
