Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking apparatus for automatically sticking labels one by one to a target object. The present invention relates to a label sticking apparatus having a function of removing dust from a label and a method of removing dust from a label.

[0002]

2. Description of the Related Art There have been proposed a number of label sticking apparatuses for peeling labels one by one from a base sheet to which a plurality of labels are temporarily attached and automatically sticking the peeled labels to an object. ing.

[0003] Most of these label sticking apparatuses are provided with a base sheet on which a plurality of labels are temporarily attached and a feeder for feeding the base sheet in a predetermined direction, though there are some structural differences. And a label applicator for peeling off the labels one by one from the substrate sheet and attaching the peeled labels to an object.

[0004]

When feeding a label or peeling off a label, a large amount of fine dust is generated. Such dust can adversely affect the operation of the labeling device. Further, some objects to which the label is to be attached may not be attached with dust (for example, a semiconductor).

For this reason, in the above-mentioned label sticking apparatus, fine dust is removed by suction using a suction pump or the like.

In recent years, the materials of labels have been diversified, and labels have been made from various materials. For example, recently, silicon has been frequently used as a material of a label because of its durability and ease of processing.

[0007] However, fine dust of silicon tends to adhere to surroundings when charged, and once adhered, considerable force is required to peel it off. In particular, when a label is fed by a feeder or peeled off by a label applicator, a large frictional force is generated, so that static electricity is easily generated, and therefore, the label is easily charged.

As described above, once a label made of a silicon-based material is charged, it cannot be easily removed by a conventional dust removing means such as a suction pump.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem in the conventional label sticking apparatus, and is intended to sufficiently remove fine silicon dust generated when a label made of a silicon material is used. It is an object of the present invention to provide a label sticking device for a labeling device.

[0010]

Means for Solving the Problems To achieve the above object, of the present invention, a first aspect of the present invention relates to a base sheet to which a plurality of labels are temporarily attached, Means, a label peeling means for peeling off labels one by one from a base material sheet and attaching the peeled labels to an object, an ion shower spray nozzle for spraying an ion shower from an oblique direction to the label, and an ion shower spray Provided is a label sticking apparatus including: a dust suction unit configured to suction dust blown off by an ion shower sprayed from a nozzle.

The label sticking apparatus according to the present invention is based on two findings of the inventor. One is that an ion shower is effective for effectively removing silicon dust, and the other is that when an ion shower is sprayed on a label from an oblique direction with respect to the label, it is most effective. The ability to remove silicon dust from labels with great efficiency.

The label attaching apparatus according to the first aspect is made based on these two findings, and makes it possible to efficiently remove silicon-based dust from the label as described later.

In particular, as described in claim 2,
The inventor has found that the silicon dust can be most efficiently removed from the label by setting the angle of the jet of the ion shower to 30 degrees.

[0014] As described in claim 3, the ion shower injection nozzle is preferably arranged near the label peeling means.

[0015] Dust from the label is generated in the largest amount when the label is peeled off. For this reason, by disposing the ion shower spray nozzle near the label peeling means, and blowing off the label dust by the ion shower sprayed from the ion shower spray nozzle, and sucking the dust by the dust suction means, the label can be efficiently printed. Dust can be removed.

According to a fourth aspect of the present invention, the dust suction means can be constituted by a suction pump and a pair of dust suction nozzles. In this case, the dust suction nozzle is provided by an ion shower injection nozzle. In the vicinity, it can be arranged on both sides of the base sheet.

Since the space below the base sheet is a space for moving the object to which the label is to be attached, it is extremely difficult to dispose the dust suction nozzle of the dust suction means below the base sheet. For this reason, by arranging the dust suction nozzles on the left and right sides of the base sheet, it is possible to efficiently arrange the dust suction nozzles while securing a space for moving the target object.

Further, as described in claim 5,
It is preferable that the present label attaching device includes an ultraviolet lamp for irradiating the label with ultraviolet light.

By irradiating the label with an ion shower and irradiating ultraviolet rays, it is possible to simultaneously remove the silicon dust and sterilize the label surface.

The above two findings can be embodied as a method. That is, claim 6 describes a process of spraying an ion shower in a direction of 30 degrees with a label while a base sheet on which a plurality of labels are temporarily attached is fed, and dust blown off by the ion shower. And a method of removing dust on a label, comprising the steps of:

Further, as described in claim 7,
It is also possible to add a sterilization process of the label by irradiation of ultraviolet rays.
