Description

[Detailed Description of the Invention] This invention relates to a label attaching device for a label printer that facilitates attaching a label issued from a label printer equipped with a label suction unit to an article.

Conventional label printers either take a label with one hand and affix it to an item (packaged item) held in the other hand, or affix the removed label to an item using air pressure.

However, these conventional methods require the use of both hands to apply the label, making it impossible to pick up the item with one hand and apply the label with that hand.

As a result, it was not possible to perform efficient, assembly-line weighing operations such as placing the next item on the scale with one hand.

In addition, labels that are attached using pneumatic pressure have a complicated structure and require a compressor, making them expensive and difficult to install on all types of label printers.

In addition, there is a type of label sticking device that is equipped with a label suction part so that the label pasting surface is outside of the label suction part and is held on the suction surface of the label suction part, but this suction surface is not fixed. Because of this, the label cannot be completely affixed to the object, and the label may turn over and cannot be affixed reliably.

This idea was made to improve the above-mentioned situation, and the label suction part of the label pasting device is moved from a fixed operating position along the traveling direction of the label peeled from the mount to a position parallel to the top surface of the main unit. A label pasting device for a label printer is provided with a rotating body having a rotating suction surface, and is capable of easily, quickly and reliably pasting a label fed out from a label feeding opening onto a product with only one hand holding the product. It is characterized by providing

This invention will be explained below with reference to an embodiment shown in the drawings.

FIG. 1 is a perspective view of a label printer of this invention, FIG. 2 is a schematic sectional view of the same example, and FIG. 3 is a longitudinal sectional view of a label pasting device of the same example.

The label printer has a label adsorption unit 1, a peeling plate 2, a platen roller 3, a thermal head 4, a guide roller 5, a press roller 6, a paper feed roller 7, a label detection unit 8, a stepping motor 9, and a label adsorption unit of a label sticking device in the main body A.
A label feeding shaft 10, a label feeding port 11, a tape feeding port 12, a rotating body 13, a box 14, a suction surface 15, an air suction port 16, a tension spring 17, a support body 18, and a support shaft 19 are provided inside.

The label supply shaft 10 is provided with labels at predetermined intervals.
The backing paper sheet with attached a... is wound, and the paper feed roller 7 and the presser roller are rotated intermittently by the activation of the stepping motor 9, and accordingly the backing paper sheet is moved intermittently.

The control circuit (
The platen roller 3 and thermal head 4, which are activated by a printing command (not shown), print the product name, code, unit price of the product, weight, processing date, expiration date, price, quantity, and other necessary numbers, letters, barcodes, and symbols. is printed, and then when the backing paper is reversed in the direction of movement of the backing paper at the label feed-out port 11 opened on the top surface of the main body A, the label a is peeled off from the backing paper and protrudes from the label feed-out port 11. .

A label suction section 1 is provided near the label feeding port 11 of the main body A of such a label printer at a position where the top surface of the label suction section 1 is substantially parallel to the top surface of the main body A.

This label suction unit 1 sucks air and when the peeled label a protrudes from the label outlet 10 by the suction force, the label adhesive side faces up and the label a is placed at a predetermined position on the bottom surface of the product. They are positioned so that they join together.

The label adsorption section 1 is attached to a box 1 as shown in FIG.
4, and a rotating body 13 provided within this box 14.

The rotating body 13 is rotatably supported on a support shaft 19 provided on a support 18 installed in the box 14, and the support 18 and one side of the lower end of the rotating body 13 are connected to each other. It is biased clockwise by a tension spring 17 provided between the two, and one or more air suction ports 16 are provided on the upper surface of the tension spring 17 to form a label suction surface 15. Since it is always biased clockwise by the spring 17, one side of the rotating body 13 is stopped at one end of the box 14 and maintained in its operating position.

In this way, the label a that has been peeled off from the tape-shaped mount and protrudes from the label outlet 11 can be adsorbed and held in the air inlet 16 with the label adhesive side up by the suction force of the air. Make it.

With this configuration, the label a that is peeled off from the mount is reliably attracted to the attraction surface of the label attraction section 1 that is parallel to the traveling direction.

Then, hold the product in one hand and use the adsorption surface 1 of the label adsorption section.
5 together with the label a, the suction surface 15 is rotated to a position parallel to the top surface of the main body A against the clockwise bias of the tension spring 17, so that the label a on the bottom surface of the product is It is possible to reliably paste parts one by one from the edges without having to paste the entire surface.

Therefore, the label a can be reliably bonded and affixed to the lower surface of the product at a predetermined position with a simple structure.

Next, when the pasting work is completed and the product is moved from the suction surface 15, the rotating body 13 is restored to the predetermined position by the clockwise bias of the tension spring 17, and is ready for the next label pasting work. .

As explained above, in the present invention, the label adsorption section is rotatable and equipped with a tension spring so that it always returns to a fixed position, so that the label that is fed out from the label feeding opening and peeled off from the backing paper is securely removed. Since the label is held on the suction surface of the label suction part and pressed together with the product against the clockwise bias of the suction surface, the label can be reliably affixed to the product. The structure has the effect of making it possible to reliably attach labels to products.

Also, although a thermal head is used as the printer in this example, it is also possible to use other printers.

In the label pasting device configured in this way, a label suction section is provided near the label feeding opening of the main body, and the label is fed out and held on the suction surface of the rotating body of the label suction section so that the label pasting side faces upward. Therefore, the label can be reliably attached to the bottom of the product by simply holding the product with one hand and pressing it from above on the label adsorption section, and therefore, the label can be firmly attached to the bottom of the product without having to grasp each unrolled label with your finger. It allows easy one-handed operation, and since the label is securely held in the position of the label suction unit, labeling can be done easily and quickly by simply placing the product on the held label. This has the practical effect of making it possible.
