Description

TECHNICAL FIELD The present invention relates to an improvement of a label sticking device, and more particularly, to a package corner label sticking device that does not require large-scale equipment, allows labels to be easily positioned, and is capable of obtaining a beautiful finish. is.

2. Description of the Related Art In order to seal a product packaging box and attach product information, etc., labels are attached to both sides of the upper lid and the bottom surface.

This labeling work is often done manually by an in-house worker, and it is difficult to work with gloves because the label has an adhesive surface, so it must be done with bare hands. There is a problem that it takes a lot of time and effort to reapply a label that has adhered to the surface or has been pasted in the wrong position.

Conventionally, there has been disclosed a device that automatically affixes a label to a corner of a package (see, for example, Patent Document 1).

However, such an apparatus requires a large-scale transportation means and the like, and there is a problem that the equipment cost increases.

Japanese Patent No. 4589152

SUMMARY OF THE INVENTION The present invention has been made in view of the problems described above in the conventional label applicator. To provide a label sticking device for the corner of a package which can easily obtain a beautiful finish.

The means employed by the inventors to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, the present invention is an apparatus for attaching labels 3 held at predetermined intervals on the surface of tape-shaped release paper 32 to corners of packages P,
An opening 11 is formed in a base 1 on which the package P can be placed and slid,
A label feeding device 2 capable of feeding the label 3 is provided, and by the label feeding device 2, a portion of the adhesive surface 31 of the label 3 can be protruded from the opening 11 in a state in which the adhesive surface 31 of the label 3 is separated from the release paper 32. hand,
In addition, a start switch 21 for the label feeding device 2 is arranged in the vicinity of the opening 11 on the upper surface of the base 1,
Further, a sensor 23 capable of optically detecting an object is provided in the label feeding device 2 in the vicinity of the opening 11, and by adjusting the unit time starting from the time when the leading edge of the label passes the reference position, the opening 11 is detected. allowing controllable projection distance of said label from
As the package P slides forward, the side surface of the package P abuts against the abutment surface of the start switch 21 together with a part of the adhesive surface 31 of the label 3 protruding upward from the opening 11. While making a part of the adhesive surface 31 stickable,
As the package P advances, the activation switch 21 is pushed in, the label 3 is bent by the edge of the opening 11, and the remaining adhesive surface 31 is peeled off from the release paper 32 and adheres to the bottom surface of the package P. By sticking, the label 3 can be attached to the corner of the package P,
By adopting the technical means that when the start switch 2 is turned back by taking out the package P, the next label 3 is fed out, the label pasting device for the corner of the package has been completed.

Furthermore, in order to solve the above problems, the present invention employs technical means of making the contact surface of the start switch 21 of the label feeding device 2 flat in addition to the above means as necessary. can be done.

According to the present invention, when the package slides forward, the side of the package comes into contact with the abutment surface of the activation switch together with a part of the adhesive surface of the label protruding upward from the opening, and the adhesive surface contacts the side surface of the package. While making a part stickable, the activation switch is pushed in by the forward movement of the package, and the label is bent by the edge of the opening, and the remaining adhesive surface is peeled off from the release paper to remove the package. By sticking to the bottom surface of the package, the label can be attached to the corners of the package.

Therefore, according to the present invention, since the structure is simple, large-scale equipment is not required, and costs can be reduced.

In addition, the positioning of the label is easy, a beautiful finish can be obtained, the manual work by the operator can be surely supported, and the usability is very good, so that the industrial utility value is extremely high.

An embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG. The sticking device of the present invention is a device for sticking labels 3 held at predetermined intervals on the surface of a tape-shaped release paper 32 to the corners of a package P. As shown in FIG.

In constructing the sticking device of the present embodiment, first, an opening 11 is formed in a base 1 on which the package P can be placed and slid. The base 1 is made of metal or plastic, has a predetermined strength, and has a flat and smooth top surface. can also

Next, a label feeding device 2 capable of feeding the label 3 is provided. The label 3 is usually used after being unwound from a roll. By picking up, the label 3 can be transported.

With this label feeding device 2 , a portion of the adhesive surface 31 of the label 3 can be protruded from the opening 11 in a state where the adhesive surface 31 has been peeled off from the release paper 32 .

Specifically, as shown in FIG. 1, the release paper 32 of the label 3 is moved along the separation plate 22, and only the release paper 32 is diffracted toward the back side of the separation plate 22 at the edge of the separation plate 22. By pulling the label 3 upright, part of the adhesive surface 31 can be peeled off from the release paper 32 due to the rigidity of the label 3 .

Further, a start switch 21 for the label feeding device 2 is arranged near the opening 11 on the upper surface of the base 1 . In the present embodiment, the contact surface of the start switch 21 can be made flat, so that the package P can be easily pressed, and the label 3 can be adhered two-dimensionally and beautifully.

As shown in FIG. 2, as the package P slides forward, the side surface of the package P is brought into contact with the contact surface of the start switch 21 together with a part of the adhesive surface 31 of the label 3 protruding upward from the opening 11 . A portion of the adhesive surface 31 can be adhered to this side surface in contact.

Further, as shown in FIG. 3 , as the package P advances, the activation switch 21 is pushed in, the edge of the opening 11 bends the label 3 , and the remaining adhesive surface 31 is separated from the release paper 32 . By peeling off and sticking to the bottom surface of the package P, the label 3 can be attached to the corners of the package P as shown in FIG.

After that, as shown in FIG. 5, when the start switch 21 is returned by taking out the package P, the device is driven and the next label 3 is delivered (set to the state shown in FIG. 1). If necessary, the start switch 21 can be additionally provided at another position, so that the first label 3 can be easily sent out when setting the first label 3 at the start of work.

In this embodiment, as shown in FIG. 6, a sensor 23 can be provided in the label feeding device 2 near the opening 11 . The sensor 23 employs a sensor capable of optically detecting an object. The projection distance of the label 3 can be controlled by adjusting the unit time starting from the time when the tip of the label 3 passes the reference position (light wave irradiation position). In the past, there were devices that determined the distance by detecting the difference in level between the label and the release paper. According to the above, the protrusion distance of the label can be stably and uniformly controlled.

Although the present invention is generally configured as described above, it is by no means limited to the illustrated embodiments, and various modifications are possible within the scope of the claims. The top surface of 1 may be horizontal or slanted depending on work efficiency.

Also, the layout of the stock positions of the labels 3 can be changed as appropriate, and any of these are within the technical scope of the present invention.
