Description

  The present invention relates to an automatic label application method and apparatus, and more particularly, to an automatic label application method and apparatus that can use a commercially available general-purpose label sheet having a plurality of rows and a plurality of rows adhered.

  In the tire manufacturing process, in order to grasp the tire manufacturing history, a label with the history information is attached to the unvulcanized tire. Conventionally, this labeling operation has been performed manually, which has been one factor that hinders productivity.

  Therefore, in recent years, there have been proposed various apparatuses and methods that automatically attach a label with history information to an unvulcanized tire (see, for example, Patent Document 1).

However, each of these proposed technologies requires a dedicated label sheet in which labels are adhered in a line along the label sheet, and a commercially available general-purpose label sheet in which labels in a plurality of rows and a plurality of rows are adhered is used. There was a problem that the cost was high because it was not possible.
JP-A-8-197637

  The objective of this invention is providing the label automatic sticking method and apparatus which can use the commercially available general purpose label sheet which adhere | attached the label of multiple rows and multiple rows.

  Another object of the present invention is to provide an automatic label applying method and apparatus capable of reliably attaching a label even if the label sheet has a missing label.

  The label automatic pasting method of the present invention that achieves the above object includes a label sheet supply means for intermittently transporting a label sheet having a plurality of rows in the width direction and a plurality of rows in the longitudinal direction adhered to one surface, and the label A label peeling means for peeling off a label to be adhered by changing a sheet conveying direction, a label adsorbing means for adsorbing a label from which the conveyance side edge has been peeled, and a label adsorbed by the label adsorbing means A label detection sensor for detecting the presence of the label sheet, and only when the presence of the label is detected by the label detection sensor, the label is adsorbed by the label adsorption means, so that One of the label sheet supply means and the label adsorbing means is labeled with a label whose transport side end has been peeled off by the label peeling means. While it is moving in the width direction of the bets, and wherein the paste peel off sequentially one by one to be attached material.

  The label automatic pasting apparatus of the present invention includes a label sheet supply means for intermittently conveying a label sheet having a plurality of rows in the width direction and a plurality of rows in the longitudinal direction adhered to one surface, and conveyance of the label sheet. The label peeling means provided in the middle of the conveyance of the label sheet, the label peeling means for adsorbing the label peeled off from the conveyance side end, and the label to be peeled off from the conveyance side end. A label adsorbing means installed at an opposing position; and a label detection sensor disposed in the vicinity of the label adsorbing means for detecting the presence of a label adsorbed by the label adsorbing means, and the label sheet supply means And one of the label peeling means or the label suction means can be moved back and forth in the width direction of the label sheet, and the label suction means is close to the label peeling means. That direction can reciprocate, and is characterized in that movably placed toward a sticking object to paste the label.

  According to the above configuration, since the label adsorbing means can be moved in the width direction of the label sheet, in the label sheet to which labels of a plurality of rows and a plurality of rows are adhered, each label is adsorbed in order from the most transported column. A commercially available general-purpose label sheet can be used because it can be peeled off by means and attached to an object. Therefore, the cost for the label sheet can be reduced.

  In addition, since the label adsorbing means can adsorb the label only when the presence of the label is detected by installing the label detection sensor, the label adsorbing means removes the portion of the label sheet when the label is missing. The next label detected by the label detection sensor can be adsorbed by skipping. Therefore, even if the label sheet has a missing label, the label can be reliably attached to the object to be pasted.

  Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows an example of an automatic label applying apparatus according to the present invention. 1 is a label sheet supply means for intermittently conveying a label sheet S, 2 is a label drawn from the label sheet S conveyed by the label sheet supply means 1. Label peeling means 3 for peeling off, 3 a label adsorbing means for adsorbing the label peeled off by the label peeling means 2, and 4 a label detection sensor for detecting the presence of the label adsorbed by the label adsorbing means 3.

  The label sheet supply means 1 includes an unwinding reel (unwinding unit) 11 for unwinding the label sheet S being wound, and a winding reel (winding) for winding the label sheet S unwound from the unwinding reel 11 Part) 12. As shown in FIG. 2, the label sheet S includes a label group M composed of a plurality of labels m in a plurality of rows (5 rows in the drawing) along the width direction and a plurality of rows (5 rows in the drawing) along the longitudinal direction. It is configured to adhere to one surface S1 at a predetermined interval in the longitudinal direction. Each label m is attached with information indicating a tire manufacturing history.

  The take-up reel 11 and the take-up reel 12 are rotatably supported by a support 14 that is erected on a base 13 disposed on the base B. A table 16 for assisting the conveyance of the label sheet S is placed on the upper end of the support member 15 erected on each base portion 13. When the take-up reel 12 is rotated by a drive motor (not shown), the label sheet S is unwound from the take-up reel 11 and passes on the horizontal upper surface 16b of the table 16 with one surface S1 facing upward. The take-up reel 12 is wound up.

  On the base B below the table 16, a moving actuator 5 for reciprocating the label sheet supply means 1 in the width direction (Y direction) orthogonal to the conveyance direction (X direction) of the label sheet S is installed. The moving actuator 5 is engaged with the table 16, and the table 16 is reciprocated in the Y direction by the operation of the moving actuator 5, so that the label sheet supply means 1 can reciprocate in the Y direction.

  The label peeling means 2 is provided at the conveyance side end 16a of the table 16 in the middle of conveyance of the label sheet S. The end surface of the end portion 16a is formed on an inclined surface 21 inclined at an acute angle, the conveyance direction of the label sheet S is changed to an acute angle, and a plurality of labels m1 in the row on the most conveyance side are simultaneously conveyed on the table 16 on the conveyance side end. I'm trying to peel it off. This label peeling means 2 reciprocates in the Y direction together with the label sheet supply means 1.

  The label adsorbing means 3 is installed above the label peeling means 2, and a label adsorbing part 31 that adsorbs the label m 1 peeled off from the conveyance side by the label peeling means 2, and ascending / descending the label adsorbing part 31. The cylinder 32 is used. The label adsorbing portion 31 is configured by connecting a vacuum pad 31b for adsorbing the label m to the lower end of a support post 31a extending vertically.

  The vacuum pad 31b is connected to a vacuum source (not shown) so that the label m1 can be adsorbed by the operation of the vacuum source. The support post 31a is connected to the lift cylinder 32, and the operation of the lift cylinder 32 causes the label adsorbing portion 31 to approach or separate from the label peeling means 2, that is, the label sheet S passing horizontally on the table 16. It can be reciprocated in the vertical direction (Z direction) orthogonal to one surface S1.

  The raising / lowering cylinder 32 is connected to a horizontal moving cylinder 7 supported by a column 6 erected on the base B, and the operation of the horizontal moving cylinder 7 causes the label suction means 3 to reciprocate in the X direction. It is possible to advance and retreat toward the unvulcanized tire T to which the label m set in the X direction is attached.

  The label detection sensor 4 is disposed at the lower end of the sensor mounting arm 41 projecting downward on the side of the lifting cylinder 32 so as to be near the label suction portion 31 of the label suction means 3. It can be moved together with the suction means 3. When the lifting cylinder 32 is at the upper standby position (FIG. 1), the label detection sensor 4 reaches the label peeling means 2 and detects whether or not the label m1 is peeled off as shown in FIG. It is supposed to be.

  A sensor 10 for controlling a motor (not shown) that rotationally drives the take-up reel 12 is provided below the label peeling means 2. This sensor 10 looks at the row of labels m1 from which the conveyance side end has been peeled off by the label peeling means 3, and if there is a label m1 from which at least one conveyance side end has been peeled off in the row of labels m1, This is detected and the motor that drives the take-up reel 12 is stopped.

  With the apparatus described above, in the present invention, the label m is automatically attached to the unvulcanized tire T as follows. First, the take-up reel 12 rotates to unwind the label sheet S from the unwind reel 11 and convey it on the table 16. When the row of labels m1 located on the most transport side of the label group M of the label sheet S reaches the label stripping means 2, the transport side end is peeled off as shown in FIG. The conveyance of the label sheet S is stopped.

  Next, the label detection sensor 4 detects the presence or absence of the label m1 below the label adsorption unit 31. When the presence of the label m1 is detected, the label suction unit 31 is lowered by the operation of the lifting cylinder 32 and the label m1 is sucked by the vacuum pad 31b. When the label adsorbing portion 31 rises to the upper standby position, the label adsorbing means 3 moves forward toward the unvulcanized tire T by the operation of the horizontal moving cylinder 7. When it reaches the attaching position indicated by the broken line in FIG. 1, the label adsorbing portion 31 descends and attaches the label m <b> 1 to the inner peripheral surface T <b> 1 of the unvulcanized tire T.

  After the pasting, when the label suction means 3 returns to the position of the solid line in FIG. 1, the label sheet supply means 1 moves in the Y direction by the operation of the moving actuator 5, and the label suction portion 31 is moved to the next label m1 in the same row. Position it above. The label detection sensor 4 detects again the presence / absence of the label m1 below the label adsorption unit 31, and repeats the same process as described above. As a result, the labels m1 in the row on the most transport side of the label sheet S are sequentially peeled off one by one by the label adsorbing means 3 and attached to the unvulcanized tire T.

  When the application of the label m1 in the row on the most transport side is completed, the take-up reel 12 rotates to unwind the label sheet S from the take-out reel 11. When the label side of the next row is peeled off by the label peeling means 2 and the sensor 10 detects it, the conveyance of the label sheet S is stopped. As shown by the dotted line in FIG. 2, the label adsorbing means 3 now peels off the labels m in the next row one by one from the opposite direction and attaches them to the unvulcanized tire T.

  As shown in FIG. 2, when there is a spot n where the label m has dropped off from the label sheet S and the label adsorbing means 3 comes above and the label detecting sensor 4 detects it, the label adsorbing means 3 adsorbs. Wait at the upper standby position without performing any action. On the other hand, the moving actuator 5 is actuated to move the label sheet supply means 1 in the Y direction, and the label adsorbing portion 31 is positioned above the next label in the same row. That is, when the label detection unit 4 does not detect the label m, the label adsorbing unit 3 skips that portion and proceeds to the next label m detected by the label detection sensor 4. Only when the presence is detected, the label m is adsorbed.

  According to the present invention described above, since the label suction means 3 can be moved in the Y direction by moving the label sheet supply means 1 in the Y direction, a plurality of columns and rows of labels m are adhered. Even for the label sheet S, each label can be peeled off in order from the row on the most transport side and attached to the unvulcanized tire T, so that it is possible to use a commercially available general-purpose label sheet and reduce costs. Can be planned.

  Further, since the label m is adsorbed by the label adsorbing means 3 only when the presence of the label m is detected by the label detection sensor 4, the label m is removed from the unvulcanized tire T even if the label m is missing. Can be securely attached.

FIG. 4 shows another example of the label adsorbing means 3 described above, in which the vacuum pad 31b arranged at the adsorbing end of the label adsorbing portion 31 is made to be a telescopic bellows structure. Further, the support post 31a is slidably supported by a cylindrical body 33 extending vertically, and a spring 34 is interposed between the upper end surface 33a of the cylindrical body 33 and the upper end flange 31a ₁ of the support post 31a. ing.

  A support plate 35 extending in the horizontal direction is fixed to the lower end surface 33 b of the cylindrical body 33, and the label detection sensor 4 is attached to the support plate 35. The support plate 35 is connected to the lower end of the telescopic rod 32a of the lifting cylinder 32 described above.

  In such a label adsorbing means 3, the vacuum pad 31 b has a telescopic bellows structure, so that even if the adsorption surface of the label m of the label sheet S is slightly inclined, it can follow it. Can be made more reliable.

  In the present invention, in the above embodiment, the label sheet supply means 1 is reciprocally movable in the Y direction. Alternatively, the label suction means 3 may be reciprocally movable in the Y direction. Alternatively, any one of the label adsorbing means 3 may be configured to reciprocate in the label sheet width direction.

  The present invention can be suitably used for affixing a label with tire manufacturing history information to an unvulcanized tire, particularly in a tire manufacturing process, but is not limited thereto. Can also be used when attaching labels.
