It is configured with.

  The label sticking means 12 includes a peel plate 48 supported by the frame F, and a press roller 50 rotatably supported on the tip side of the peel plate 48 via a support arm (not shown). The peel plate 48 can peel the label L from the release sheet RL by abruptly reversing the belt-like sheet S on the leading end side, and the peeled label L is transported below the peel plate L. It is pressed and stuck by the press roller 50 to the adherend W conveyed on the apparatus 51.

  In the plane of the frame F, at a predetermined position on the upstream side in the feeding direction of the belt-like sheet S, in this embodiment, near the upper right corner of the frame F, the introduction portion 53 of the belt-like sheet S and two guide rollers 54 and 55 are arranged. The introduction portion 53 includes shafts 58 and 57A that are non-rotatably supported by the frame F, and a sponge roller 57B that is rotatably provided on the shaft 57A, and a belt-like sheet that passes between the sponge roller 57B and the shaft 58.

  In the present embodiment, in a state where the roll R is supported by the shaft member 15, a buffer region A as a twist correction unit is formed between the outer periphery of the roll R and the introduction portion 53. The buffer area A is for securing a surplus length by bending a predetermined length of the belt-like sheet S fed from the roll R supported by the shaft member 15 downward by its own weight. And while being able to respond | correspond to the continuous sticking of the label L, the twist of the said strip | belt-shaped sheet | seat S is correct | amended and it guides to the said introduction part 53 side. Therefore, on the lower side of the buffer area A, a pair of sensors 66 and 67 for detecting an extra length of a certain length are supported by the arms 68 protruding from the frame F.

  Next, the label sticking method in this embodiment is demonstrated.

  When the roll support device 11 supports the roll R, the projection amount of the shaft 43 is set in advance according to the diameter of the roll R to be supported, the nut member 19 of the shaft member 15 is retracted, and the collar 18 Is adjusted to be equal to or smaller than the inner diameter of the paper tube P. Then, the axis of the shaft member 15 is controlled to be in a substantially horizontal position via the angular displacement means 46. This is because, when a roll-like body that is easily collapsed, such as a label roll, is targeted, if the outer peripheral side of the roll is tilted while being held in hand, the roll collapses from the center side.

  Next, the shaft member 15 is inserted into the paper tube P until the roll R hits the disk 28. After the insertion, the angular displacement means 46 is operated in a predetermined manner to be angularly displaced in an inclined posture so that the distal end side of the shaft member 15 is at a position vertically higher than the proximal end side. Then, the nut member 19 is screwed into the shaft body 17, the collar 18 is expanded and displaced, and the inner peripheral surface of the paper tube P is pressed against the outer peripheral surface of the collar 18, thereby completing the support of the roll R.

  After the support of the roll R is completed in this way, the belt-like sheet S is pulled out from the roll R and is wound around the peel plate 48 through the introducing portion 53 and the guide rollers 54 and 55, and the driving roller 61 and the pinch roller 62 Then, the lead end is fixed to the winding roller 64.

  When the wrapping of the belt-like sheet S is completed, the motor M1 is driven by turning on an automatic sticking switch of an operating device (not shown), and the sensors 66 and 67 in the buffer area A are fed out until the belt-like sheet S is detected. When the motors M2 and M3 are driven and the label L is stopped at a predetermined position of the peel plate 48, the standby state is established.

Then, the adherend W transported on the transport device 51 is detected by a sensor (not shown), and the sticking operation is started while the label L is peeled off. In this operation, the driving roller 61 is rotated by the driving of the motor M2, so that a repetitive output is applied to the belt-like sheet S. On the other hand, the winding roller 64 is rotated by the driving of the motor M3 so Taken.

  When the belt-like sheet S is fed out and the sensors 66 and 67 in the buffer area A no longer detect the belt-like sheet S, the shaft member 15 is driven by the motor M1, and the extra length of the belt-like sheet S is always in the buffer area A. It is controlled so that the minutes are secured.

  The belt-like sheet S in the buffer area A hangs down in a twisted state due to the inclined posture of the shaft member 15, but the twist is corrected in the middle of being guided to the introduction portion 53 side, so that the belt-like sheet S is twisted. There is no such thing as paying out. In addition, a separate sensor may be provided to detect that the roll R is consumed and the diameter of the roll R is reduced, and the slide mechanism 44 is controlled in a direction to reduce the protruding length of the shaft 43. it can. Thereby, it is kept so that the drooping form of the strip | belt-shaped sheet | seat S in the buffer area | region A may not change a lot.

  In addition, when replacing | exchanging roll R, it can carry out in the reverse procedure to mounting | wearing operation | work.

However, the roll support device 11 according to the present invention includes a roll obtained by winding a belt-like sheet into a roll shape. The present invention can be applied to a general apparatus for feeding or winding a belt-like sheet into a roll. At this time, even when the belt-like sheet is applied to a roll-up device, the buffer region can be provided immediately before the winding direction with respect to the shaft member. That is, in the label sticking apparatus 10, when the roll is exchanged without using up the roll R, the release sheet RL is cut at a position past the peel plate 48, and the shaft member 15 is moved in the direction opposite to the feeding direction by the motor M1. It may be driven and wound up. Further, the shaft 58 of the introducing portion 53 can be driven via a motor, and by cooperating with the sensors 66 and 67, the twist of the belt-like sheet can be corrected and wound while forming the buffer region of the belt-like sheet S. .

  The shaft member 19 can also be provided so as to be movable in the vertical and horizontal directions. In this case, a drive device such as an air cylinder may be interposed between the holder 41 through which the shaft 43 is inserted and the plate 38.

  Further, the label sticking means 12 is configured to press the label L against the adherend W by the press roller 50, but may be replaced with other pressing means such as a vacuum grid having a holding surface for sucking the label. Not disturb.

  Moreover, it can replace with the disc 28 which comprises a collapse prevention means, and can also employ | adopt the some arm etc. which were orient | assigned to the radial direction from the shaft main body 17. FIG.
