  By the way, in recent years, the functions required of tires are diversified and it is common to produce a wide variety of tires in small quantities. However, if a label supply cassette is prepared for each type of tire, the manufacturing cost increases, In addition to preparing a label supply cassette, a mount roll having labels for a plurality of lots is prepared for each type of tire, and the mount roll to be mounted on the label supply cassette is exchanged according to the type of tire to be produced. For this reason, it is necessary to store the mount roll mounted before the replacement in a predetermined storage location, and there is a problem that it takes time to replace the mount roll of the label supply cassette. There is also a problem that a storage place for storing a mount roll prepared for each type of tire is required.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to perform label replacement without interrupting tire production and to quickly and easily perform label replacement work. In addition, the present invention is to provide a label sticking device that does not need to prepare a mount roll for each label even when the sticking label differs depending on the kind of sticking object.

  In order to achieve the above object, the present invention is directed to a label sticking device that peels a label from a strip-like mount having a plurality of labels attached to one surface at predetermined intervals in the longitudinal direction and sticks the label to a sticking object. In this case, the mount is cut into an arbitrary length and is wound in a roll shape without using a winding core, and a label storage section that can be stored in contact with the other surface of the mount drawn from the label storage section. A contact member, a winding roller that can be wound around the outer peripheral surface by bending the mount immediately after passing through the end of the contact member toward the other surface side, and a mount that has passed through the winding roller can be accommodated. A label supply cassette having a mount collection unit and a winding roller are provided so that their outer peripheral surfaces face each other, and the mount is sandwiched between the roll rollers and the mount is placed on the mount collection unit side by a predetermined distance. Move The adsorbing member for adhering the adsorbed label to the object to be applied and the label supply cassette are replaced with another label supply cassette. And a cassette mounting portion that can be mounted.

  As a result, the label supply cassette is attached so as to be exchangeable with other label supply cassettes. For example, a plurality of label supply cassettes are prepared and labels corresponding to the type of tire to be produced next are supplied in advance. By attaching it to the cassette, the label can be exchanged without interrupting the production of the tire. Moreover, since the mount cut into an arbitrary length is stored in the label storage unit without using the core, for example, predetermined information is printed only on the number of labels corresponding to the number of tires produced, The portion of the mount on which the label is affixed can be cut and mounted on the label supply cassette.

  According to the label sticking device of the present invention, it is possible to replace the labels without interrupting the production of the tires by exchanging the label supply cassettes, and it is possible to perform only a predetermined number of labels corresponding to the number of tires produced. The information on the label can be printed, and the mount on the part where the label is affixed can be cut and attached to the label supply cassette, so that a large amount of label remains in the label supply cassette after the production of the tire is completed. Therefore, when replacing the label of the label supply cassette, the mount mounted before the replacement can be discarded without storing. In other words, the label replacement operation of the label supply cassette can be performed quickly and easily, which is extremely advantageous for improving productivity. Also, since it is possible to cut out and use the required amount of mount from a commercially available mount roll having a large amount of labels, it is not necessary to prepare a mount roll for each type of tire, for example, a storage place for storing the mount roll Can be reduced.

The drive roller 40 is disposed so that the outer peripheral surface thereof faces the free roller 24 of the cassette 20 supported by the cassette holder 30, and the mount SH is sandwiched between the drive roller 40 and the free roller 24.

  The label suction mechanism 50 is fixed to the lower side of the vacuum head 51 as a suction member that sucks the label LA of the mount SH on the guide 23, and protrudes to the right side in FIG. A vertical cylinder comprising a head drive plate 52 formed on the head, a rod 53 fixed to the head drive plate 52 and extending in the vertical direction, and a well-known air cylinder that supports the rod 53 movably in the vertical direction. 54, a horizontal cylinder 55 made of a well-known air cylinder that supports the vertical cylinder 54 so as to be movable in the left-right direction in FIG. 1, and an upper end surface of the vacuum pad 51, and protrudes to the right in FIG. And a positioning guide 56 formed in such a manner. Further, the head drive plate 52 and the horizontal cylinder 55 constitute an adsorption member moving mechanism.

  The vacuum head 51 is provided with a suction hole (not shown) on the right end surface in FIG. 1, and sucks air from the suction hole to suck the label LA.

  The head drive plate 52 is formed so as to be insertable into the gap between the guide 23 and the back plate 21a. When the vacuum head 51 is brought into contact with the label LA of the mount SH on the guide 23, the head drive plate 52 in FIG. The right end surface is in contact with the outer peripheral surface of the free roller 24.

  When replacing the cassette 20 of the label sticking apparatus configured as described above, the levers 30b of the cassette holder 30 are rotated to the front side (FIG. 2), and the cassette 20 is pulled out from the cassette holder 30. Remove (Figure 3). Subsequently, another cassette 20 with a label LA corresponding to the tire to be produced next is inserted from the front side to the back side of the cassette holder 30 (FIG. 4), and each lever 30b is rotated to the back side ( FIG. 5). As a result, the outer peripheral surface of the free roller 24 and the outer peripheral surface of the drive roller 40 face each other, and the mount SH is sandwiched between the free roller 24 and the drive roller 40.

  Subsequently, the leading label LA is positioned so as to be positioned slightly below the upper end of the guide 23 by a sensor (not shown) and the driving roller 40 controlled based on the detection result of the sensor (FIG. 6).

  Here, when a new mount SH is mounted on the removed cassette 20, the mount SH is pulled out as much as necessary from a commercially available mount roll (not shown) having thousands to tens of thousands of labels, and then produced. Predetermined information is printed only on the number of labels LA corresponding to the number of tires, the mount on the portion where the printed label LA is affixed is cut, and the mount is wound in a roll shape to the label storage unit 22 Accommodate. Therefore, a large amount of label LA does not remain in the cassette 20 removed from the label holder 30 for replacement, and the mount mounted before replacement can be discarded without storing.

  Subsequently, when the label LA is pasted to the unvulcanized tire TA by the label pasting device to which the cassette 20 is attached, first, the vacuum head 51 and the head driving plate 52 are moved to the guide 23 side by the horizontal cylinder 55, and the guide The vacuum head 51 is brought into contact with the top label LA of the mount SH on 23, and the label LA is adsorbed by the vacuum head 51 (FIG. 7). At this time, the head drive plate 52 contacts the outer peripheral surface of the free roller 24. Further, the vertical cylinder 54 is set in a state in which the rod 53 is movable in the vertical direction.

  Next, by rotating the driving roller 40 by a predetermined angle, the free roller 24 is rotated by the rotation of the driving roller 40, and the head driving plate 52 is moved upward by the rotation of the free roller 24, so that the upper side of the mount SH. In synchronization with the movement, the vacuum head 51 moves upward to a position exceeding the upper end of the guide 23 (FIG. 8). Here, since the mount SH is bent to the other surface side of the mount SH immediately after passing through the guide 23, the label LA is peeled off from the mount SH and adsorbed to the vacuum head 51. That is, since the label LA does not bend due to its rigidity when the mount SH is bent, the label LA is reliably peeled off from the mount SH. Further, since the vacuum pad 51 moves in synchronization with the mount SH and also moves upward to a position exceeding the upper end portion of the guide 23, the variation in the suction position of the label LA on the vacuum pad 51 can be reduced.

  Subsequently, the vacuum pad 51 and the pad drive plate 52 are moved away from the guide 23 by the horizontal cylinder 55 (FIG. 9), and the vacuum pad 51, the pad drive plate 52 and the rod 53 are moved upward by the vertical cylinder 54. After that, the vacuum pad 51 is moved downward and toward the unvulcanized tire TA by the vertical cylinder 54 and the horizontal cylinder 55 so that the positioning guide 56 is locked to the inner peripheral surface of the unvulcanized tire TA from above (see FIG. 10). Here, by locking the positioning guide 56 to the inner peripheral surface of the unvulcanized tire TA from above, the position in the height direction of the vacuum pad 51 with respect to the unvulcanized tire TA is always a predetermined position. Variations in the position of the label LA that is affixed to the vulcanized tire TA can be reduced.

  Next, the label LA adsorbed to the vacuum pad 51 by the horizontal cylinder 55 is brought into contact with one end in the width direction of the unvulcanized tire TA, and the adsorption of the label LA by the vacuum pad 51 is released (FIG. 11). The vacuum pad 51 is moved by the vertical cylinder 54 and the horizontal cylinder 55 to a predetermined standby position where the vacuum pad 51 can come into contact with the label LA to be next sucked (FIG. 12).

  Thus, according to this embodiment, since the cassette 20 is attached to the cassette holder 30 so as to be exchangeable with other cassettes 20, a plurality of cassettes 20 are prepared and the type of tire TA to be produced next is set. By attaching the corresponding label LA to the other cassette 20 in advance, the label LA can be exchanged without interrupting the production of the tire.

  Further, the label storage unit 22 of the cassette 20 is formed so as to be able to store a mount SH that is cut into an arbitrary length and wound in a roll shape without using a winding core, and the number of sheets according to the number of tires to be produced. The predetermined information is printed only on the label LA, and the mount SH on which the label LA is attached is mounted on the cassette 20 by cutting the portion of the mount SH on which the label LA is attached and winding it in a roll. As a result, there is no large amount of label LA remaining in the cassette 20 that has been removed after the production of the tire, and when mounting the label LA of the cassette 20, the mount SH that was mounted before replacement can be stored. Can be discarded without That is, the replacement operation of the label LA of the cassette 20 can be performed quickly and easily, which is extremely advantageous for improving productivity.

  Further, the required amount of the backing sheet SH is drawn from a commercially available backing roll having thousands to tens of thousands of labels LA, and predetermined information is printed only on the number of labels LA corresponding to the number of tires to be produced. Since the mount SH where the LA is pasted can be cut and mounted on the cassette 20, there is no need to prepare a commercially available mount roll for each type of tire, and the storage space for storing the mount roll is reduced. Can do.

  In addition, the cassette holder 30 can be attached to the cassette 20 from the front side by guide portions 30a provided at both ends in the width direction, and each guide portion 30a is provided with a lever 30b and each lever 30b. Since the cassette 20 is mounted on the cassette holder 30 and the levers 30b are rotated to the back side, the cassette 20 is restricted from moving toward the front side. Since the cassette 20 can be removed by rotating the front side 30b, the cassette 20 is securely supported by the cassette holder 30, and the cassette 20 can be easily attached to and detached from the cassette holder 30. .

  Further, the label storage unit 22 is formed so as to cover the outer peripheral surface side of the mount SH wound in a roll shape from the outside, and an opening 22 a through which the mount SH can be drawn out is provided in a part of the label storage unit 22. Therefore, the mount SH wound without using the winding core can be securely held in the cassette 20, and the mount SH can be smoothly supplied to the guide 23 side.

  Further, the collection guide 25a is formed so as to extend along one surface of the mount SH that passes through the free roller 24 and hangs downward, and the other surface side of the mount SH from the lower end of the collection guide 25a. The recovery unit body 25b is formed so that the curved tip is directed upward, and the mount SH that hangs down after passing through the free roller 24 is the recovery guide 25a and the recovery unit body 25b. Since the mount SH is wound in a roll shape with the other side inward, it is easy to take out the mount SH when replacing the label LA of the cassette 20. This is extremely advantageous in quickly changing the label LA.

  Further, the vacuum head 51 is attracted to the label LA of the mount SH on the guide 23 before reaching the upper end of the guide 23, and the vacuum pad 51 is moved in the moving direction of the mount SH in synchronization with the movement, Further, the vacuum pad 51 is moved to a position beyond the upper end of the guide 23, and the mount SH is bent at the upper end of the guide 23, whereby the label LA is surely peeled from the mount SH and the peeled label LA is Since the vacuum pad 51 that moves in synchronization with the mount SH is attracted, the variation in the suction position of the label LA on the vacuum pad 51 can be reduced, and the label LA is accurately applied to the unvulcanized tire TA. This is extremely advantageous.

  In this embodiment, the label LA is applied to the unvulcanized tire TA. However, the label LA is applied to an unvulcanized rubber member, a vulcanized tire, an industrial product other than the tire, and the like constituting the unvulcanized tire. It is also possible to paste.

  Further, in the present embodiment, the tension is applied to the mount SH on the guide 23 by its own weight, but a brake that presses the mount SH on the guide 23 toward the guide 23 with a predetermined force is applied to the base plate 10. It is also possible to provide a predetermined tension to the mount SH on the guide 23.
