Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a label sticking device for sticking a label to an article or the like.

[Prior Art] Conventionally, as a device for attaching a label to an article or the like, after the labels that are issued one by one are adsorbed at the tip of an air cylinder equipped with a vacuum generator, the label is activated by operating the air cylinder. There is known a method of attaching the article to the surface of an article or the like that has moved and stopped.

Here, as the label that is issued in the previous step that is adsorbed by the air cylinder, one that is continuously arranged at substantially constant intervals on the surface of the tape-shaped mount is used. Then, these labels are continuously punched on a surface of a wide tape-shaped mount in a plurality of rows at substantially constant intervals, and then the portions other than the labels are wound and removed, and substantially the center of each label in each row is cut off to It is designed to be used after being processed into a row of tape.

[Problems to be Solved by the Invention] However, there is a problem in that each label that has passed through the above-described steps cannot obtain accuracy with respect to the position with respect to the tape width, the arrangement interval between the labels, and the like. It was

Also, if the punching teeth are too deeply inserted when punching the label, when the label is peeled from the backing sheet when issuing the label, the rear edge of the label becomes difficult to peel off from the backing sheet, and the label is sucked and held by the air cylinder. There was a problem that the label was printed in the wrong direction.

That is, in the above-described conventional label sticking apparatus, the label is stuck to the article or the like without correcting the variation during the label processing, so that there is a problem in that the accuracy of the sticking position of the label to the article or the like is low.

Therefore, in order to solve the above problems, the present invention can always adsorb and hold the label at the same position even if there are variations in the label position during label processing, and it is constant according to the distance to the adherend such as an article. It is an object of the present invention to provide a label sticking device capable of sticking a label to the position of with high accuracy.

[Means for Solving Problems] Next, means for solving the above problems will be described with reference to FIGS. 1 and 2 corresponding to the embodiment.

The label sticking apparatus of the present invention is a label sticking apparatus that sucks and holds an issued label 11 and sticks it to an adherend 18, and a label suction unit 9 provided with a suction pad 10 that sucks and holds the label, Positioning means 17 provided so as to surround two sides of the label sucked on the suction pad, and the label suction part with respect to the label issuing direction until the two sides of the label come into contact with the positioning means. And a label positioning moving unit 5 for moving the label obliquely.

[Operation] The label 11 issued by the label issuing device is sucked and held by the suction pad 10 of the label suction unit 9. The label suction unit 9 is moved by the label positioning moving means 5 to move the label 1
It moves diagonally with respect to the issuing direction of 1. Then, when the two sides of the label 11 come into contact with the stopper 17 which is the positioning means, the parallel direction and the orthogonal direction to the issuing direction of the label 11 are positioned. In this state, after the positioning by the stopper 17 is released, the sticking moving means 2 moves the label suction portion to a position close to the sticking surface of the sticking object 18. After that, the suction pad 10 of the label suction unit 9 moves until it comes into contact with the sticking surface of the sticking target 18, or the label 11 sucked and held by the suction pad 10 is stuck to the sticking target 18 by blowing out air.

[Embodiment] FIG. 1 is a schematic side view showing an embodiment of a label sticking apparatus according to the present invention, and FIG. 2 is a partially omitted perspective view of the label sticking apparatus according to the same embodiment.

The label sticking apparatus 1 is generally composed of a plurality of air cylinders and a vacuum generator.

First, the sticking air cylinder 2 is installed downward, and a rectangular moving block 4 is provided at the tip of the piston 3. Rotation of the moving block 4 when the sticking air cylinder 2 is actuated is restricted by a rotation stop guide portion (not shown), and the moving block 4 can be moved vertically while keeping horizontal. Further, the moving block 4 is provided with an adsorption label moving air cylinder 5 as a moving means on the bottom surface. The suction label moving air cylinder 5 is attached so as to operate in a diagonal direction of the bottom surface of the moving block 4 in a direction orthogonal to the moving direction of the moving block 4. Further, a suction label moving unit 7 is provided at the tip of the piston 6 of the suction label moving air cylinder 5 so as to be located directly below the moving block 4. In this suction label moving unit 7, a compressor (not shown) is provided with a vacuum generator (label suction ejector) 8
Connected through. Further, the suction label moving portion 7 is provided with a label suction portion 9 protruding in the same direction as the operating direction of the sticking air cylinder 2 described above. A suction pad 10 is provided at the tip of the label suction unit 9, and the suction surface 10a of the suction pad 10 has a label 11a.
The label 11 is formed smaller than the above size, and the label 11 can be suction-held by operating the above-described vacuum generator.

Next, the stopper moving air cylinder 12 is fixed to the end portion of the moving block 4 described above via the bracket 13. A stopper mounting portion 15 having a vertical portion and a horizontal portion 15a is provided at the tip of the piston 14 of the stopper moving air cylinder 12. The horizontal portion 15a of the stopper mounting portion 15 is formed in a substantially L shape in which one corner of a rectangular plate is cut out, and a label positioning portion 16 is formed in this cutout portion. The label positioning portion 16 is provided at a position surrounding the two sides of the suction pad 10 described above. In addition, this label positioning unit 16
In this case, a plurality of cylindrical stoppers 17 processed by Teflon (trade name) or the like are arranged in an L shape so that the label 11 does not adhere to the surface of the label 11 by the glue of the label itself. These stoppers 17 are provided so that the curved wall surface thereof projects from the edge of the positioning portion 16. Then, the label 17 is positioned by these stoppers 17.

Next, the operation of the label sticking apparatus configured as described above will be described with reference to the time chart of FIG. 3 and a partially enlarged view of the label sticking apparatus shown in FIGS. 4 to 7.

First, when the label 11 is issued 31 from the label issuing device, as shown in FIG. 4, the vacuum generation mounting is activated at the same time as the issuance, and the label 11 is adsorbed 32 and held on the adsorption pad 10. Next, after the label issuance end 33, the suction label moving air cylinder 5 is actuated 34, and as shown in FIG. 5, the suction label moving portion 7 holding the label 11 by suction is directed toward the label positioning portion 16 toward the label 11 issuing direction. In contrast, it is moved diagonally (arrow A in FIG. 5). At this time, as shown in FIG. 6, the stopper 17 contacts the two sides of the label 11 to position the label 11.

Next, when the label positioning is completed 35, as shown in FIG. 7, the label positioning portion 16 moves up 36 by the operation of the stopper moving air cylinder 12, and at the same time, the moving block 4 moves down 37 by the sticking air cylinder 2. To do.
Then, the label suction section 9 provided on the moving block 4 via the suction label moving air cylinder 5 and the like attaches the label 11 suction-held on the suction pad 10 to the article 18 as an adherend. To do. Then, at the same time as the attachment, the vacuum generator releases 39 the suction.

After sticking the label 11 to the article 18, the sticking air cylinder 2 raises the moving block 4 to 40, and the stopper moving air cylinder lowers the label positioning portion 41. The suction label moving air cylinder also returns to the original position 42 at this time. Then, the apparatus waits until the next label issuance, and when the next label is conveyed from the label issuing device, the above operation (1 cycle) is repeated.

Therefore, in the label sticking apparatus 1 configured as described above, even if the position accuracy of the label 11 is deviated when the label 11 is issued, the label 11 is moved by the suction label moving cylinder 5 and the stopper 17 is used. Because it is configured to be attached to the article after accurate positioning,
The label can be attached to the article with high accuracy without changing the attaching position.

In this embodiment, the sticking air cylinder is moved down to press and stick to the article.However, by providing a vacuum breaking valve in the ejector part of the vacuum suction device for sticking the label, the sticking is performed at the time of sticking the label. For goods that are things,
The label may be attached by blowing air. As a result, it is possible to accurately attach the label to the moving article.

[Advantages of the Invention] As described above, according to the label sticking apparatus of the present invention,
By moving the label suction portion obliquely with respect to the label issuing direction by the label positioning moving means, the two sides of the label are brought into contact with the positioning means and positioned, so that the label is parallel to the label issuing direction. The label can be positioned in the direction orthogonal to and in a single operation, and the label can always be adsorbed and held at the same position. Regardless of variations in the label attachment position due to errors in the label tape width during label processing, There is an effect that the label sticking position with respect to the sticking object can be obtained with high accuracy. Moreover, since the label is always adsorbed and held at the same position, it is possible to apply the label to the adherend at a fixed position according to the distance to the adherend, which has the effect of improving the sticking accuracy.
