Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automatic label pasting device, and more specifically to an automatic label pasting device for pasting a label on a moving workpiece.

[Conventional technology]

2. Description of the Related Art Conventionally, labeling devices have been provided for affixing labels such as price tags and barcodes to various works.

In such a conventional label sticking device, the label sticking device is held by hand and the labels are sequentially stuck onto the surface of the workpiece.

However, when there are many works to be pasted,
Since it is inefficient to attach labels while holding the device in the hand, automatic label attaching devices are now being provided.

In such a label sticking device, in order to automatically stick labels, the sticking section is formed to be movable in the vertical direction from the fixed frame of the automatic label sticking device, Labels are pasted by placing a workpiece below this pasting section.

For example, as such a conventional automatic label pasting device, there is a device described in Japanese Utility Model Publication No. 13931/1983.

This label pasting device is for pasting labels on spherical objects of irregular sizes, and the movement of the workpiece, such as a watermelon, is stopped when pasting the label. Ta.

[The problem that the idea attempts to solve]

In such a conventional automatic label pasting device, the workpiece is moved intermittently, and the label is pasted onto the workpiece while the workpiece is in a stationary state when pasting the label.

This is an automatic label pasting device that only moves in the vertical direction, so if you try to paste a label while the workpiece is moving, the pasting part of the automatic label pasting device will This was caused by the fact that the label moved relative to the workpiece, causing the label to shift or part of the label to peel off, making complete adhesion impossible.

On the other hand, as mentioned above, in order to move the workpiece intermittently, the intermittent movement device is complicated, and the distance of the intermittent movement must be changed depending on the size of the workpiece, so the overall device is extremely difficult to move. It was becoming more complex and more likely to break down.

Therefore, in the present invention, the automatic label pasting device itself can only move in the vertical direction.
In addition, even if the workpiece to which the label is to be pasted is moved continuously, the pasting part of the automatic label pasting device is formed to be swingable in the moving direction of the workpiece and to be able to move upwards, so that it can be moved continuously. The purpose of this is to make it possible to attach labels to workpieces, to improve the attaching efficiency, and to simplify the moving device.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a label automatic system that attaches labels sequentially supplied from a label supply mechanism to a moving workpiece by an attaching section that is moved downward by a vertical movement mechanism. In the pasting device, the pasting part is formed of a fixed frame fixed to a vertical movement mechanism and a rocking body pivotally supported by the fixed frame so as to be able to swing in the moving direction of the workpiece. The present invention is characterized in that a contact part is provided at the lower end of the vibrating body to hold the label and come into pressure contact with the workpiece, and the contact part is formed to be movable upward.

[Effect]

The automatic label pasting device according to the present invention descends toward the moving workpiece and eventually comes into contact with the workpiece.

The label is attached to the workpiece when it comes into contact with the workpiece, but the workpiece moves while it is being attached.

However, in the present invention, the sticking part that actually sticks the label to the workpiece can swing in the direction of movement of the workpiece and can move upward, so the sticking part The label is moved upward and shaken at the same time, so that the label can be completely attached without shifting the label or peeling off part of the label.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, one embodiment of the present invention will be described according to an illustrated example.

FIG. 1 is a side view showing the vertical movement mechanism 10 and the label supply mechanism 20 as blocks, and FIG. 2 is a front view thereof.

In both figures, the automatic label pasting device according to the present invention applies labels 30 sequentially supplied from a label supply mechanism 20 to a workpiece being moved by a pasting unit 50 that is moved downward by a vertical movement mechanism 10. This is a device for attaching to 40.

The labels 30 are attached in advance to the wrapping paper at equal intervals, and each label 30 is peeled off from the wrapping paper and attached to the surface of the workpiece 40.

The label supply mechanism 20 is for supplying one label 30, the bottom surface of which is a pasting surface, to the pasting section 50 which is moved up and down by the vertical movement mechanism 10.

The vertical movement mechanism 10 uses a cylinder (not shown), a cam mechanism, a gear mechanism, etc. to move the adhesive part 50.
This is for moving up and down. Further, this vertical movement is made possible in consideration of the height of the workpiece 40 and the like, from a height that does not collide with the tallest workpiece 40 to a height that allows the label 30 to be attached to the lowest workpiece 40.

Furthermore, this vertical movement mechanism 10 can be controlled so that it automatically stops after descending a predetermined distance when the heights of the workpieces 40 are the same. Conversely, when attaching the label 30 to the workpiece 40 that is not the same height, it is necessary to detect that the attachment part 50 has contacted the workpiece 40 and stop the effect of the vertical movement mechanism 10. As means for such detection, for example, a proximity sensor to the workpiece 40 may be provided in the pasting section 50, or a pressure sensor may be provided to detect contact between the pasting section 50 and the workpiece 40. That is required.

Further, the pasting part 50 includes a fixed frame 51 fixed to the vertical movement mechanism 10, and an oscillating body 52 pivotally supported on the fixed frame 51 so as to be able to oscillate in the moving direction of the workpiece 40.
A contact portion 53 is provided at the lower end of the vibrating body 52 to hold the label 30 and come into pressure contact with the workpiece 40.

The fixed frame 51 is formed in a substantially horizontal U-shape when viewed from the front, and a swinging shaft 54 for pivotally supporting the swinging body 52 is formed inside the U-shaped portion. The adjustment screw 55 fixed to the fixed frame 51 and in contact with the oscillating body 52 is connected to the oscillating body 52 which is pivotally supported by the fixed frame 51.
This is to regulate the swing angle of one of the two.

The oscillating body 52 has a shaft support 57 located inside the U-shaped portion of the fixed frame 51 formed from the center to the upper part of the horizontal beam 56, and is movable up and down on a vertical shaft 58 at both ends of the horizontal beam 56. It is held in The upper end of this vertical shaft 58 is connected to the stop body 5 on the upper part of the cross beam 56.
9, the lower end is fixed to the contact portion 53, and a spring 60 is compressed between the cross beam 56 and the contact portion 53. Therefore, in this oscillator 52, due to its own weight and the elastic force of the spring 60, the stop body 59 is in contact with the upper end surface of the cross beam 56, and the contact portion 53 is located at the lowest end. When a load is applied that pushes the contact part 53 upward from below, the contact part 53 can rise.

The contact part 53 holds the label 30 supplied from the label 30 supply device on its lower surface, and the workpiece 40
This is for attaching the label 30 by pressing the top surface. Also here, the contact part 5
3. The label 30 is held on the lower surface by negative pressure suction or the like.

Note that the work 40 placed below the contact portion 53 in FIG. 1 is placed on a conveyor 42 that is moved by a moving device 41.

Next, the operation of the automatic label pasting device according to the present invention will be explained.

First, the sticking part 50 is raised to a predetermined position by the vertical movement mechanism 10.

After the sticking section 50 has risen to a predetermined position, the label 30 is held on the lower surface of the contact section 53 of the sticking section 50 by the label supply mechanism 20.

Next, the adhesion part 50 is lowered toward the workpiece 40 by the vertical movement mechanism 10.

Then, the contact part 53 of the sticking part 50 will come into contact with the moving workpiece 40 soon.

Then, the label 30 held on the lower surface of the contact portion 53 is attached to the upper surface of the workpiece 40.

However, even when the label 30 is being pasted on the workpiece 40, the workpiece 40 continues to move.

Therefore, although the workpiece 40 is still moving when the contact part 53 contacts the surface of the workpiece 40, in the automatic label 30 pasting apparatus according to the present invention, the vibrating body 52 of the pasting part 50 moves the workpiece 40. Since the contact portion 53 is shaken in the moving direction, the label 30 to be attached is also shaken as the workpiece 40 moves.
In many cases, the label 30 is displaced or a part of the label 30 is peeled off.

Furthermore, when the contact part 53 is pressed into contact with the workpiece 40 during the pasting work of the label 30, the vertical shaft 58 to which the contact part 53 is fixed at the lower part resists its own weight and the elastic force of the spring 60. and move upward.

Further, when the workpiece 40 moves while the contact portion 53 is in contact with or in pressure contact with the workpiece 40, the shaking body 52 is shaken as the workpiece 40 moves, but the relationship between the workpiece 40 and the shaking shaft 54 is Since the distance is constant, the contact portion 53 is pushed upward and oscillated.

In this way, the label 30 can be stuck more reliably, and the oscillating body 52 of the adhering section 50 moves around the oscillating shaft 54, and the contact section 53 moves upward, so that the contact section 53 is in pressure contact. Even if the workpiece 40 is moved, the contact portion 53
Since the label is also shaken and raised, there is no possibility that the label will be misaligned.

[Effect of idea]

As explained above, the present invention allows automatic label pasting even though the automatic label pasting device itself only moves in the vertical direction and the workpiece to be pasted with labels is moved continuously. The pasting section of the device is formed so that it can swing freely in the direction of movement of the workpiece and can move upwards, making it possible to stick labels on moving workpieces, improving pasting efficiency and simplifying the moving device. It is ivy.
