Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label printing apparatus, which sequentially prints labels on a roll-shaped label surface without release paper so that they can be easily attached to an appropriate adherend. The present invention relates to a label printing device which is designed to be put out.

[0002]

2. Description of the Related Art Conventionally, as a label printing apparatus, since the label has the form of a label sheet adhered to a release mount, it can be handled like plain paper, and when printing, it is used by the platen of the printer. The label paper is wound around, the print head is made to face the label surface, and the printing operation is performed in the same manner as plain paper.

[0003]

However, when a printed label is attached to an adherend, the label is peeled off from the release mount and used, so that the release paper of the label paper remains. . SUMMARY OF THE INVENTION It is an object of the present invention to provide a label printing device which has a simple structure and can accurately print on a roll-shaped label paper without release paper.

[0005]

In order to achieve the above-mentioned object, a label printing apparatus of the present invention has a roll having no release paper so that the back surface of the printing surface is coated with an adhesive and can be rotated and pulled out. The rotary shaft to which the label is attached and the roll label attached to the rotary shaft is pulled out from one end and the adhesive surface coated with the adhesive is temporarily adhered and transferred.
A belt-shaped platen composed of an endless belt wound around a plurality of rolls, and a print head provided facing the predetermined position where the belt-shaped platen is temporarily adhered to and moved at a predetermined position. .

[0006]

The adhesive is applied to the back side of the printing surface, and the label without release paper that is rotated and pulled out is temporarily adhered to the belt-shaped platen and transferred to perform printing. Since the belt-shaped platen is stretched over a plurality of rolls, the label for which printing has been completed is peeled off at a peeling angle as compared with a circular platen having the same circumference as the belt-shaped platen when peeled off from the platen. It can be made large and can be easily peeled off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. 1 is a side sectional view of the label printing apparatus of the present invention, and FIG. 2 is an enlarged view of a partial side sectional view of the label printing apparatus of FIG.

As shown in FIG. 1, the label printing apparatus P showing the present invention is a roll-shaped label, which is a hollow label core 1.
The pressure sensitive adhesive is applied to the back surface (inner surface side) and the release surface is applied to the printing surface side so as not to be adhered by the pressure sensitive adhesive. The roll-shaped label 1 is adapted to be inserted by being inserted into a rotary shaft 15 which is attached inside a frame of a label printing apparatus. The label L of the roll-shaped label 1 is pulled out by the paper feeding roller 2. A belt-shaped platen composed of a short belt 5 made of a silicone resin, which is stretched over a plurality of rollers 4, 6, and 7, is arranged at the subsequent stage of the sheet feeding roller 2. Of the plurality of roller groups, the roller 6 is a drive roll. A sticking roller 3 is provided above the roller 4 positioned as a feed roll so that the adhesive application surface of the transported label is adhered to the short belt 5 and transported. On the upper part of the roller 6, a stripping roller 8 around which the short belt 5 is wound and which is temporarily adhered to the short belt 5 for peeling off a label is provided. Further, between the rollers 4 and 6 and inside the infinite belt 5, a plastic template 13 for preventing the indentation of the infinite belt is provided, and the infinite belt 5 is separated to face the plastic template 13 so as to face the thermal insulation. A print head 9 composed of a head is provided. Below the print head 9, an ink ribbon R is supplied from a ribbon core 10 so that the ink ribbon R is wound around the winding ribbon core 11. As the print head 9, a print head having a print width in the axial direction of the roll-shaped label 1 is adopted, and a print head having a print width of 50 to 10 cm is used.

The label L printed in this manner is successively fed out from 10 and 11 and cut by a cutter K (specifically not shown) or the like provided in the subsequent stage,
It can be attached to an adherend.

In the present embodiment, the print head may be a conventionally known printing system such as a dot system or a laser printing system other than the thermal head. Regarding the roll-shaped label, when the label is peeled off, a release agent is applied so that it is easy to peel off, but a pressure-sensitive color developing agent is applied on the printed surface, and a transparent film layer also serving as a release layer is provided on it. In this case, a label may be used in which a pressure sensitive color former on the lower surface of the transparent film layer is colored by a thermal head to print without providing an ink ribbon as a printing mechanism. Need to

[0011]

As is apparent from the above description, according to the present invention, it is possible to print on a roll-shaped label having no release paper. Therefore, when the printed label is attached to an adherend, the release paper is Since it does not remain, the release paper itself does not need to be treated, and the work efficiency can be greatly improved. Further, even in the printer configuration, since the label surface that is temporarily adhered to the short belt-like platen that is stretched over a plurality of rollers is used for printing, the label can be easily peeled off after printing and the printer itself It has an effect that the structure can be simplified and is industrially beneficial.
