Description

  The present invention relates to a label adhering and sticking method and a label adhering and sticking apparatus for peeling off a label from a mount, adsorbing the peeled label, and attaching it to a tire.

2. Description of the Related Art Conventionally, devices as described below are known as devices that peel off a label having an adhesive applied to the back surface from a belt-like mount and attach the peeled label to a tire.
This device passes the band-like mount with the label adhered while passing back at the edge of the release plate, peels the label from the band-like mount, and adsorbs the surface of the peeled label to the suction head, It was stuck on a certain tire.
In this type of device, it is difficult to completely remove the label from the belt-like mount, and for this purpose, for example, the label is completely removed by blowing air from the back side to the label from which the tip has been peeled off. It was considered to peel it off from the strip.
As another contrivance, the edge portion of the peeling plate is separated from the peeling plate main body, and the edge portion at a position separated from the peeling plate main body in advance after the label with the tip portion peeled is sucked to the suction head. It has also been considered that the label adsorbed by the suction head can be peeled off from the mount without being moved with respect to the suction head by moving the sheet to the peeling plate body side (see, for example, Patent Document 1). ).
JP 2002-338136 A

However, the above-described conventional apparatus has the following problems.
In the former device, which uses air as an auxiliary material to peel off the label, there is a problem that the label does not peel off from the belt mount due to variations in the adhesive strength of the label to the belt mount, or the label blows off. It was. In order to prevent the label from blowing off, when the label is peeled off, the peeled label may be temporarily received by a cradle disposed on the back side of the label. The problem of adhering to the surface occurs. In addition, when the label sucked by the suction head is moved together with the suction head and attached to the tire, the cradle interferes and hinders the movement of the suction head.

  On the other hand, in the latter apparatus having the structure in which the edge portion is separated from the peeling plate body, the edge portion must be separated from the peeling plate body, and the movement amount of the edge portion with respect to the peeling plate body must be controlled. The configuration becomes complicated. In addition, since the edge portion itself is extremely small, the drive system of the edge portion is required to be downsized, and implementation may be difficult and costly.

The present invention has been made in view of the above circumstances, and an object thereof is to be able to reliably peel off a label from a belt-like mount with a simple configuration.
Another object of the present invention is to attach the label once peeled off from the belt-like mount to the tire while adhering it to the adsorption head without adhering it to other components.
Furthermore, another object of the present invention is that when the label once peeled off from the belt-like mount is adsorbed to the adsorption head or moved to the tire and attached, there is no part that obstructs the movement of the adsorption head, and the adsorption head is smooth. Therefore, it is possible to secure a safe movement and to shorten the paste processing time.

The present invention employs the following means in order to solve the above problems.
The label adhering and sticking method according to the present invention includes a step of conveying the belt-like mount to which the label is adhered to the release plate, and folding the conveyed belt-like mount at the edge portion of the release plate and drawing it in the direction opposite to the conveyance direction. And a step of adsorbing the label peeled off from the band-shaped mount by the suction head when the band-shaped mount is folded back at the edge portion of the peeling plate, and an adhesive surface of the label sucked by the suction head The peeling nail is brought into contact with the non-adhesive surface and pushed to the non-adhesive surface side, and the rear end portion of the label is peeled off from the belt-shaped mount, and the label sucked by the suction head is moved to the tire together with the suction head. And a step of affixing to the tire.

  In this label adhering and sticking method, the belt-like mount to which the label is adhered is conveyed to the release plate, and the conveyed belt-like mount is folded back at the edge portion of the release plate and drawn in the direction opposite to the conveyance direction. At this time, the label located at the edge portion of the peeling plate is gradually peeled off from the front end portion to the belt-like mount in an attempt to maintain a flat state due to its rigidity. The label from which the tip is peeled is sucked by the suction head. The rear end of the label tends to remain on the belt-like mount, but the peeling claw comes into contact with the adhesive surface of the label and pushes the label toward the non-adhesive surface. Thereby, the rear-end part of a label can be reliably peeled from a strip | belt-shaped mount. Thereafter, the peeled label is moved to the tire while being stuck to the suction head, and is attached to the tire.

  The label adhering and sticking apparatus according to the present invention conveys the belt-like mount to which the label is adhered to the release plate, and folds the conveyed belt-like mount at an edge portion of the release plate in a direction opposite to the conveyance direction. A belt-shaped backing sheet transport means for drawing, a movable suction head for sucking the label peeled off from the belt-shaped backing paper when the belt-shaped backing paper is folded back at the edge portion of the peeling plate, and the suction head Further, a label peeling means for peeling the rear end portion of the label from the belt-like mount by pressing a peeling claw on the pressure-sensitive adhesive surface of the label and pressing it toward the non-stick surface side, and the label sucked by the suction head A suction head moving means for moving the suction head to the tire together with the suction head and attaching the suction head to the tire.

  In this label adhering and sticking apparatus, the belt-like board transport means transports the belt-like board to the peeling plate, and the conveyed belt-like board is folded back at the edge portion of the peeling plate and pulled in the direction opposite to the carrying direction. At this time, the label located at the edge portion of the peeling plate is gradually peeled from the front end portion with respect to the belt-like mount in an attempt to maintain a flat state due to its rigidity. The label from which the tip is peeled is sucked by the suction head. The rear end of the label tends to remain on the belt-like mount, but the label peeling means brings the peeling claw into contact with the adhesive surface of the label and pushes the label toward the non-adhesive surface. Thereby, the rear-end part of a label can be reliably peeled from a strip | belt-shaped mount. Thereafter, with the peeled label being adsorbed by the adsorbing head, the adsorbing head moving means moves the adsorbing head together with the tire to affix the label to the tire.

In the label adhering and pasting apparatus according to the present invention, the label peeling means causes the peeling nail to abut on the adhesive surface of the label in a point contact state or a line contact state so that a rear end portion of the label is formed in the belt shape. It is characterized by peeling from the mount.
In this label adhering and sticking device, the peeling nail contacts the adhesive surface of the label in a point contact state or a line contact state, and the rear end portion of the label is peeled off from the belt-like mount, so that the label is difficult to adhere to the peeling nail. . For this reason, not only when the label is completely peeled off from the belt-like mount, but also after that, the state where the label is adsorbed by the adsorption head can be maintained.

The label adhering and sticking device according to the present invention is characterized in that the peeling nail includes a plurality of cutting edge portions arranged in parallel to each other and in contact with an adhesive surface of the label.
In this label adhering and sticking device, a plurality of cutting edge portions arranged in parallel with each other are brought into contact with the adhesive surface of the label, that is, in a state where there are a plurality of line contact states, the label is peeled off from the belt-like mount. The label can be peeled off from the belt-like mount without changing its posture while preventing it from adhering to the peeling nails.

The label adhering and sticking apparatus according to the present invention is characterized in that the label peeling means includes a retraction mechanism that retreats the peeling claw to a position that does not hinder the movement of the suction head.
In this label suction sticking apparatus, the peeling claw can be retracted to a position that does not hinder the movement of the suction head by the retracting mechanism. For this reason, when moving the suction head to the tire while the label is sucked, the peeling claw does not interfere with the suction head, and the suction head can be moved smoothly, and the suction head can be secured. By previously retracting the peeling claw before moving the head to the tire side, it is possible to shorten the sticking processing time.

The label adhering and sticking apparatus according to the present invention is characterized in that the label peeling means is provided with a plurality of types of the peeling nails, and one of them is detachably attached to the nail support portion. .
In this label adhering and sticking device, it is possible to select the most suitable nail for peeling off the label from the strip mount and attach it to the nail support portion according to the type and size of the label, and change the posture of the label The effect which can be peeled off from a strip | belt-shaped baseboard can be heightened further.

  According to the present invention, the label from which the leading end is peeled can be sucked by the suction head, and the trailing end of the label can be reliably peeled off from the belt-like mount. Moreover, after that, the peeled label can be moved to the tire while being stuck to the suction head, and can be attached to the tire.

Embodiments according to the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the label adhering and sticking apparatus 1 according to this embodiment transports the strip-shaped mount 3 to which a large number of labels 2 are adhered to the release plate 4 and also transfers the transported strip-shaped mount 3 to the release plate. 4 is a belt-like mount conveying means 5 that is folded back at the edge portion 4a and drawn in the direction opposite to the carrying direction, a suction head 6 that sucks the label 2 whose tip is peeled off from the belt-like mount 3, and the back surface (adhesive surface) of the label 2 The peeling claw 7 is brought into contact with and pressed to the surface side (non-adhesive surface side), whereby the label peeling means 8 for peeling the rear end portion of the label 2 from the belt-like mount 3 and the label 2 sucked by the suction head 6 are removed. The suction head 6 is moved to the tire 9 together with the suction head 6 and attached to the tire 9. The suction head moving means 10 includes a fluid cylinder 10 such as air or hydraulic pressure.

  The belt-like board transport means 5 includes a paper feed roll 12 around which the belt-like board 3 is wound in a plurality of stages, a collection roller 13 that winds up the belt-like board 3 from which the label 2 has been peeled off, and these paper feed rollers 12. A plurality of idle rollers 14 disposed along the transport path of the strip-shaped mount 3 and the strip-shaped mount 3 from which the label 2 has been peeled off, on the downstream side of the peeling plate 4, are peeled off. A pair of pull-in rollers 15 and 15 that pulls in a direction away from the plate 4 (a direction opposite to the transport direction of the belt-like mount to which the label 2 is adhered) is provided.

The peeling plate 4 includes an edge portion 4a set at a predetermined acute angle in order to peel off the label 2 adhered to the band-shaped mount 3 by folding the band-shaped mount 3 back. Further, the peeling plate 4 is arranged so that the side surface 4b with which the belt-like mount 3 first contacts is oriented in the substantially vertical direction so that the label 2 to be peeled off by the edge portion 4a faces in the substantially vertical direction (FIGS. 2 and 2). 3).
A printer 16 is disposed on the upstream side of the peeling plate 4. The printer 16 prints necessary information on the label 2, for example, tire type, manufacturing factory, lot number, etc. in the form of a barcode.

  The suction head 6 is formed in a hollow shape, and the hollow portion is connected to air suction means (not shown) such as a vacuum pump. The front end surface portion 6a facing the label of the suction head 6 has a large number of holes, and a negative pressure is introduced into the hollow portion via air suction means, so that the label 2 by the front end surface portion 6a Adsorption is possible.

  The suction head 6 is attached to the tip of the piston rod of the fluid cylinder 10, and the operation of the fluid cylinder 10 causes the tip surface 6 a to retreat a predetermined distance from the one side surface 4 b of the peeling plate 4 in the direction where the printer 16 exists. Label (2) where the tip surface portion 6a is in the same plane as the side surface 4b of the peeling plate 4 and the tip surface portion 6a is moved forward by a predetermined distance toward the tire 9 and the label 2 is sucked by the suction head 6. Is controlled so as to reach any one of the pasting positions (C) for pasting to the tire 9 (see FIGS. 1 and 3).

  As shown in FIG. 3, the label peeling means 9 supports the peeling claw 7 that contacts the back surface of the label 2 and pushes the label 2 to the front surface side, supports the peeling claw 7, and rotates around the pin 19a. And a fluid cylinder 20 that is attached to the end of the claw support 19 opposite to the side that supports the peeling claw 7 via a link 19b and rotates the claw support 19 With.

  The peeling claw 7 comes into contact in a point contact state or a line contact state so that the label 2 is less likely to adhere when contacting the back surface of the label 2. As a specific configuration of the peeling claw 7, for example, as shown in FIG. 8 (a), a plurality of (for example, three) claw portions 7b are formed at the tip of the claw base portion 7a. There is one in which the cutting edge portions 7ba formed at the tip of the portion 7b are arranged in parallel with each other and at the same height. In addition, as shown in FIG. 8 (b), there is a case where only one claw portion 7b having a blade edge portion 7a is formed at the tip of the claw base portion 7a. In addition, although not shown in the figure, it is also conceivable that a plurality of needle members are arranged at the tip of the claw base portion 7a so as to be parallel to each other and at the same height.

  A plurality of types of peeling nails 7 are prepared as described above, and one of them is detachably attached to the nail support portion 19 by a fixing means such as a screw.

As shown in FIG. 2, the peeling claw 7 is retracted from the protruding position (d) where the claw portion 7 b can come into contact with the back surface of the label 2 and the moving range of the suction head 6 by operating the fluid cylinder 20. It is controlled to reach any one of the positions (e). Here, the fluid cylinder 20 constitutes a retracting mechanism for retracting the peeling claw 7 to a position that does not hinder the movement of the suction head 6.
When the claw portion 7b is in a protruding state (d) in which the claw portion 7b can come into contact with the back surface of the label 2, the suction head has the blade edge portion 7ba in the vicinity of the edge portion of the peeling plate and in the label adsorption state (b). The position is set so as to be arranged at a position separated from the front end surface portion 6a of the label 6 by the thickness t of the label 2 (see FIG. 5).
In FIG. 1, reference numeral 21 denotes a bar code reader for reading the information on the label 2 attached to the tire 9.

Next, a method for adsorbing a label using the label adhering / applying apparatus configured as described above and adhering the adsorbed label to a tire will be described.
As shown in FIG. 1, the belt-like mount 3 fed from the paper feed roller 12 is wound around the collection roller 13 through a plurality of idle rollers 14, a peeling plate 4, and a pair of drawing rollers 15 and 15.

  In this state, the drawing rollers 15 and 15 are rotationally driven by a motor (not shown), and the belt-like mount is conveyed as indicated by an arrow in FIG. When the label 2 adhered to the belt-like mount 3 reaches a position facing the printer 16, the printer 16 operates and prints a predetermined barcode on the label 2. The printed label 2 is conveyed while being in sliding contact with one side surface 4b of the release plate 4 together with the belt-like mount 3. At this time, when the printed label 2 reaches the edge portion 4a of the peeling plate 4, the belt-like mount 3 overlapping the label 2 is gradually folded back by the edge portion 4a. At this time, since the label 2 keeps its original shape due to its rigidity, the label 2 is gradually peeled off from the front end portion with respect to the belt-like mount 3.

Then, when the label 2 is peeled off by a predetermined amount, the suction head 6 that has been in the standby position (A) in advance moves forward to the label suction position (B) by driving the fluid cylinder 10 (see FIG. 4). As a result, the tip of the label 2 is sucked by the suction head 6. Thereafter, the drawing rollers 15 and 15 are rotationally driven to further convey the belt-like mount 3. At the same time, the peeling claw 7 previously in the retracted position (e) is rotated by driving the fluid cylinder 20 to reach the protruding position (d) (see FIGS. 4 and 5). As a result, the peeling claw 7 comes into contact with the back surface of the label 2 sucked by the suction head 6, and the label 2 is pushed to the front surface side to peel off the rear end portion of the label 2 from the belt-like mount 3.
That is, the label 2 is completely peeled off from the belt-like mount 3 and delivered to the suction head 6.

At this time, when using the three-claw structure shown in FIG. 8A as the peeling claw 7, a plurality of cutting edge portions 7ba arranged in parallel with each other are brought into contact with the back surface of the label 2, That is, since the label 2 is peeled off from the belt-like mount 3 in a state where there are a plurality of line contact states, the label 2 can be reliably peeled while preventing the label 2 from adhering to the peeling claw 7. In addition, the label 2 can be peeled off from the belt-like mount 3 while being held in parallel with the front end surface portion 6a of the suction head 6 without changing the posture of the label 2.
When the label 2 is small, or when the adhesive applied to the back surface of the label 2 is extremely strong, it is shown in FIG. 8B instead of the peeling claw 7 having a three-claw structure. A peeling claw 7 having a single claw structure may be used.

  After the label 2 is peeled off from the strip-shaped mount 3, the transport of the transport mount 3 is stopped at an appropriate timing. Thereafter, the fluid cylinder 20 is driven to move the peeling claw 7 at the protruding position (d) to the retracted position (e) (see FIG. 6). After the peeling claw 7 is retracted in this way, the fluid cylinder 10 is driven, and the suction head 6 that sucks the label 2 at the label suction position (b) is indicated by a two-dot chain line in FIG. The adhering label 2 is affixed to the tire 9 by moving to the affixing position (c) in the adsorbed state.

In this label suction sticking device 1, the peeling claw 7 can be retracted from the moving range of the suction head 6 by driving the fluid cylinder 20 which is a retracting mechanism. For this reason, when the suction head 6 is moved to the tire 9 while the label 2 is sucked, the peeling claw 7 does not interfere with the suction head 6 and the smooth movement of the suction head 6 is ensured. In addition, before the suction head 6 is moved to the tire 9 side, the sticking processing time can be shortened by retracting the peeling claw 7 in advance.
Incidentally, it is conceivable to change the moving path of the suction head instead of retracting the peeling claw, but in this case, the apparatus becomes complicated.

  Through the above operation, the label 2 on which a predetermined barcode is printed can be adsorbed to the adsorption head 6 and attached to the tire 9. The label 2 attached to the tire can be read by the barcode reader 21 to check whether or not the predetermined label 2 is attached to the tire 9.

Thereafter, the fluid cylinder 10 is driven again, and the suction head 6 at the sticking position (C) is returned to the initial standby position (A).
Hereinafter, by repeatedly performing the above operation, the label 2 printed with a predetermined barcode can be adsorbed to the adsorption head 6 and attached to the tire 9.

The present invention is not limited to the above-described embodiment, and can be appropriately changed in design without departing from the spirit of the invention.
For example, in the above-described embodiment, the suction head 6 and the peeling claw 7 are moved by the fluid cylinders 10 and 20, respectively, but not limited thereto, by a rack and pinion mechanism that uses the driving force of the motor, Alternatively, the suction head 6 or the like may be moved by a linear motor.
In the embodiment, when the suction head 6 is at the label suction position (b), the suction head 6 is set so that the front end surface portion 6 a is flush with the one side surface 4 b of the peeling plate 4. However, the position is not limited to this, and the position may be set so that the tip surface portion 6a is closer to the tire side (right side in FIG. 2) than the one side surface 4b of the peeling plate 4.
In the embodiment, when the label 2 is transferred to the suction head, the separation head 7 is moved to the protruding position (d) after the suction head 6 is moved to the label suction position (b). Without being limited to this, the peeling claw 7 may be moved to the protruding position (d) at the same time as the suction head 6 is moved to the label suction position (b).
