Description

  The present invention relates to a label sticking device, and more particularly to a label sticking device capable of sticking a label having information on a member or the like to a green tire or the like accurately and efficiently in a tire manufacturing process or the like.

  Conventionally, in a tire manufacturing process or the like, for example, a label having tire information is attached to the periphery of a bead portion outside the tire of a green tire before vulcanization. The tire information includes the manufacturer, the date and time of manufacture, the tire type, and the like, and is used for product management, sorting, etc., and enables reliable traceability, which is very important.

  As the label, for example, a label having a surface printed with a two-dimensional code or the like is used, and in order to improve work efficiency, a label mount wound in a reel having a large number of labels continuously spaced at predetermined intervals. The label is pasted at a predetermined position using an automatic pasting apparatus.

  In the conventional automatic sticking device, one end of the label mount is pulled out to move the label in the supply direction, and the supply direction is changed by folding it to the opposite side of the surface on which the label is provided. After a part of the sheet is peeled off, the label is sucked with a suction head or the like and peeled off from the mount (for example, see Patent Documents 1 and 2).

  However, with this device, the behavior of the label becomes unstable until it is adsorbed from the part where it is peeled off, and the peeled parts stick to each other, making it impossible to use the label. There are problems such as dropping off, and each time the sticking device has to be stopped, man-hours and time are required, resulting in poor work efficiency.

Further, there is a problem in that the label cannot be attached to a predetermined position with high accuracy by being held by the suction head in a state where the position is shifted.

  The label supply device 4 includes a drive system unit of a drive roller 13 and a free roller 14, and drives the drive roller 13 with a drive source (not shown) with one end portion of the label mount 3 being sandwiched between the rollers 13 and 14. By doing so, the label mount 3 is pulled out and the label 2 is supplied. In this embodiment, the label 2 is provided on the lower surface of the label mount 3. An intervening plate 9 is provided below the free roller 14, and the function of the intervening plate 9 will be described later.

  The mount guide 10 is a cylindrical body having a rectangular cross section, and has a size that allows the label mount 3 to be pulled out to be inserted smoothly from one end side to the other end side and to be smoothly pulled out while preventing vertical and horizontal misalignment. Yes.

  In this embodiment, since the label supply device 4 is disposed above the mount guide 10, the label mount 3 coming out from the other end of the mount guide 10 is pulled out in a bent state in the supply path. Will be.

  That is, the other end portion of the mount guide 10 serves as a supply direction changing section 5 and changes the supply direction of the label 2 to the opposite side of the label mount 3 from the surface on which the label 2 is provided. The supply direction changing unit 5 may be provided separately from the mount guide 10.

  The suction head 6 has a suction hole at the tip, and has a structure capable of sucking the label 2 provided on the label mount by vacuum. The suction head 6 is attached to the tip of the operating rod 20 and is attached to the suction rod working cylinder 19. It is possible to advance and retract with respect to the label 2 supplied by operation.

  A synchronous operation rod 18 of the synchronous movement cylinder 17 is connected to the operation rod 20 via a connecting portion 21. The synchronous operation rod 18 can advance and retreat in the supply direction of the label 2, and the suction head 6 can move in the supply direction of the label 2 by this connection.

  The label sticking device 1 according to the present embodiment further includes a positioning device 8 that can stop the supplied label 2 at a predetermined position, a tensioner 11 that applies tension to the label mount 3, and after the label 2 is peeled off. A cutting device 7 for cutting the label mount 3 and a label mount winder 15 for winding the label mount 3.

  The positioning device 8 includes a position sensor 8a that detects the position of the supplied label 2, and a control unit 8b that controls the driving of the driving roller 13 based on a detection signal from the position sensor 8a. According to a preset program, the driving roller 13 is stopped by the detection signal of the position sensor 8a, and the label 2 can be stopped at a predetermined position, so that the label 2 can be cueed.

The tensioner 11 is provided with a contact plate 11a having a flexible contact surface and a coil spring 11b, and the label mount 3 is pressed against the lower surface of the top surface of the mount guide 10 by the biasing force of the coil spring 11b. Is giving tension. This prevents sagging of the label mount 3 and enables the label 2 to be supplied smoothly and accurately. In order to bring the contact plate 11a and the label mount 3 into contact with each other, the lower surface of the mount guide 10 around the tensioner 11 is opened.
After the label 2 is peeled off, the label mount 3 is automatically wound and accommodated in a label mount winding portion 15 having a C-shaped housing by driving of a drive roller.

  The cutting device 7 is disposed downstream of the drive roller 13 in the pulling-out direction of the label mount 3, and the label mount 3 passing between the cutting edges of the pair of cutting blades 7a and 7a is closed to a predetermined length. It can be severely cut. Accordingly, when the label mount 3 is replaced, the label mount 3 that is no longer necessary does not get in the way, and the label mount 3 can be replaced quickly.

  Hereinafter, based on FIGS. 2-8, the process until the label sticking apparatus 1 peels the label 2 from the label mount 3, and sticks it on the green tire 16 is explained in full detail. The driving of the driving roller 13 and the operation of both cylinders 17 and 19 in this series of pasting processes are controlled by the control unit 8b.

  2 and 7 show the first process. FIG. 2 is a front view of the main part, and FIG. 7 is a plan view of a part of the configuration in FIG. 2 (viewed from above). The label mount 3 is pulled out by driving of the driving roller 13 to supply the label 2, and the label 2 to be peeled off is cued by the positioning device 8. At this time, the suction head 6 is located on the return side by the synchronous operation rod 18 and moves toward the label 2 by the operation of the operation rod 20.

  An intervening plate 9 is disposed on the side of the label mount 3. The intervening plate 9 has a rotation shaft 9 a at one upper end portion, and can rotate, and can also move in the supply direction of the label 2. In this process, the intervening plate 9 is not in contact with the free roller 14.

  3 and 8 show the second process. FIG. 3 is a front view of the main part, and FIG. 8 is a plan view (part viewed from above) showing a part of the configuration in FIG. The suction head 6 comes into contact with the label 2 for suction, and the operation of the operating rod 20 causes the suction head 6 to come into contact with the intervening plate 9, and the interposition plate 9 moves around the rotation shaft 9a. And the free roller 14. That is, the suction head 6 sucks the label 2 on the upstream side in the supply direction with respect to the supply direction changing unit 5 in the label supply path. When the intervening plate 9 is sandwiched, the synchronous operation rod 18 is in a free state.

  In the third process, as shown in FIG. 4, the height position of the actuating rod 20 is fixed, the synchronous actuating rod 18 is in a free state, and the interposed plate 9 and the suction head 6 sandwiched receive a driving force. The free roller 14 moves in the label 2 supply direction in synchronization with the label 2. As described above, the structure in which the intervening plate 9 is sandwiched facilitates the synchronous movement of the suction head 6 and the label 2.

  The means for synchronous movement is not limited to this. For example, the synchronous movement is performed by means such as controlling the operation of the synchronous operation rod 18 to move the suction head 6 in the same direction and in the same direction as the movement speed of the label 2. It can also be made.

  Here, the label mount 3 changes the moving direction upward along the free roller 14 by the supply direction changing unit 5, but the suction head 6 that sucks the label 2 changes the direction beyond the supply direction changing unit 5. Without progressing. Since the label supply direction after the direction change, that is, the moving direction of the label mount 3 is on the opposite side of the surface of the label mount 3 on which the label 2 is provided, when passing through the supply direction changing section 5, A force to release the label 2 by its own elastic force acts on the leading end of the supply direction of the label 2, and the adsorbed label 2 is easily peeled off from the label mount 3 by using the peeling force as a trigger. When the label 2 is peeled off, the driving roller 13 is stopped and the supply of the label 2 is interrupted.

  As described above, in the present invention, since the force to peel off the label 2 itself is used, it can be surely and easily peeled off. As a result, it is possible to minimize loss such as stopping the apparatus without being able to peel off, and it is possible to increase the efficiency of labeling.

  The angle A formed between the supply direction of the label 2 changed by the supply direction changing unit 5 and the supply direction before the change is determined as appropriate depending on the material of the label 2, the adhesive force, and the like. become.

  In the fourth process, as shown in FIG. 5, the suction head 6 is moved to the green tire 16 at a predetermined position by the operation of the synchronous operation rod 18 and the operation rod 20, and the label 2 is pressed by the operation rod 20. Affixed to the green tire 16.

  In the fifth step, as shown in FIG. 6, the suction head 6 is brought into contact with the interposition plate 9 by the operation of the synchronous operation rod 18 and the operation rod 20, and the synchronous operation rod 18 is moved backward to move the interposition plate 9. Move back to the original position.

  Thereafter, the process returns to the state of the first process in FIG. 2 again, and the first to fifth processes are similarly repeated. As described above, in the present invention, the label 2 is continuously held by the suction head 6 until it is peeled off from the state on the label mount 3 and attached to the green tire 16 at a predetermined position. There is no dropout or displacement of the label 2 in the process, and it is possible to attach it at a predetermined position with high accuracy. Accordingly, it is possible to improve the efficiency of label attachment.

  In this embodiment, the object to which the label 2 is applied is the green tire 16, but the present invention is not limited to this, and the label 2 can be attached to another object such as a tire member.
