Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for discriminating the type of a wound tack label to be attached to a product in order to display the type of the product and the like, and a method for supplying and attaching a tack label.

[0002]

2. Description of the Related Art Labels on which brands, sizes, uses, and the like are printed are generally used to indicate the types of products. In recent years, with the diversification of consumer needs, manufacturers who supply industrial products in particular are forced to produce small quantities and many types of products, and the types of labels for identifying products are also quite large.

[0003] On the other hand, the supply and attachment of labels to products are generally automated as part of a production line. The most important thing in this process is to supply and affix a label that matches the product content. In particular, when producing many kinds of products on one production line, the risk of label mistakes increases, and there is no effective way to prevent it.
The current situation is that we are struggling to deal with this.

As a method of determining the type of a roll-shaped material such as a wound tack label, for example, Japanese Patent Application Laid-Open No. 2-265855 discloses a symbol for determining the type of the label on the hollow inner wall surface of the core of the wound label. And a method of reading it with an optical reader. By this method, it is possible to prevent label sticking error to some extent.

[0005] However, a method of integrally attaching a reader to a supporting device for holding a wound tack label as shown in the embodiment of the above-mentioned patent and reading an identification symbol attached to the inner wall surface of the core hollow is disclosed in Japanese Patent Application Laid-Open No. H11-287,086. There were various problems. That is, the inner diameter of the core hollow portion is limited, it is difficult to stably and reliably print the identification symbol or paste the printed matter, and the problem of reading accuracy related thereto,
And problems caused by the high frequency of replacement of the winding tack label in response to a large number of products of a small quantity, such as contamination of the identification symbol due to repeated use of the same winding tack label after being repeatedly removed and attached. There are problems such as peeling of the printed identification code and workability at the time of exchanging the rolled tack label (it takes time to insert the reading device into the supporting device because the reading device is attached to the supporting device as a pair).

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method capable of always accurately determining the type of label. In particular, it is an object of the present invention to provide a label discriminating method that can be suitably used for discriminating labels in a supply and sticking process of a label that is automatically incorporated in a production line for a small number of products.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to print, on each label, an identification symbol representing the label type on the back surface of a release label of a rolled tack label composed of release paper and a tack label. This is achieved by a method of determining the type of the winding tack label, wherein the identification symbol printed on the back surface of the release paper of the winding tack label is read for each label by an optical reader. .

According to the present invention, the accuracy of the discrimination and the label error are greatly improved as compared with the conventional discrimination of the winding unit of the label by discriminating the supplied labels one by one.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
FIG. 1 is a perspective view of a wound tack label showing one embodiment of the present invention. FIG. 1A is a perspective view seen from the back side,
FIG. 1B is a perspective view seen from the front side. The winding tack label (1) has the same position as the label where the tack label (3) cut out by die cutting on the front side of the band-shaped release paper (2) and the identification symbol (4) that symbolizes the label type on the back side. The configuration is printed on. As the identification symbol used in the present invention, an optically readable bar code, a Karla code, or the like is preferable.

In the present invention, the positional relationship between the tack label (3) and the identification symbol (4) is that the identification symbol is printed at the same pitch as the tack label in the sense that the identification symbol is determined for each tack label. Is preferred. In particular, as shown in FIG. 1A, it is preferable to print the identification symbol at the tack label position, because the reading accuracy of the optical sensor is improved (the light transmittance of the portion to be inspected is preferably low).

FIG. 2 is a schematic diagram showing a tack label supply and sticking process in a product production line. The wound tack label (1) set in the label supply / pasting device (21) is supplied after being unwound in the direction of the arrow. The identification symbol printed on the back side of the release label of the wound tack label is read by the optical sensor (8) for each label, and label type discrimination control is performed to determine whether the tack label matches the product (7) on the production line. The determination is made by the device (9). If not, the production line shuts down and an alarm sounds.

The tack label conveyed in the direction of the arrow is stripped from the release paper by setting the holding angle of the band release paper to an acute angle with the roller (11).
The tack label peeled from the release paper is attached to a product (usually a packing case in which the product is stored) conveyed by the product conveyor (22) by a label applicator (6) having a suction plate (12). Can be The band-shaped release paper from which the tack label has been peeled is wound around a roller (13).

The number of labels in a roll of the tacky label varies depending on the size of the label and the like, but the number of labels in a roll is usually about 500 to 3000. As described above, when a small number of products of various types are produced on a single production line, the product brand is frequently changed, and accordingly, the winding tack label is also replaced. Therefore, it is repeatedly performed that the wound tack label is replaced before the whole of the entire roll is used up, and that it is set in the label supply / pasting device and used again in the middle of use.

In such a production situation, the method of the present invention for discriminating the identification of each label is very suitable,
The conventional problem of discrimination due to contamination of the identification symbol and peeling of the printed matter is eliminated.

The above embodiment is an example in which all information determined by the manufacturer, such as brand, size, application, etc., as necessary, is supplied and affixed as final product labels as product information.

The embodiment described below is an example in which the label is provided with versatility. That is, there are many cases where the display of the final product is different due to a difference in size or the like while using the same intermediate product. In such a case, using the same information across the final products, for example, using a label in which only the brand is displayed in advance, additional information suitable for the product flowing on the production line, such as the size and application, is added to the label in the label supply and attachment process. An additional printing method can be adopted.

The above embodiment will be described with reference to FIG. The supply and affixing of the label are as described above. First, it is determined by the optical sensor (8) and the type determination control device (9) whether or not the supplied label matches, and additional information is printed in accordance with product information previously input to a CPU (not shown). Printing is performed on the label by the ribbon (14) and the printing device (15). Reference numeral (16) denotes a winding ribbon on the supply side, and reference numeral (17) denotes a printing ribbon on the winding side. The label on which the additional information is printed is affixed to the product transported by the product transport conveyor (22) by the roller (11) and the label affixing device (6). By the above method, the same label can be used for the final product group produced from the same intermediate product, and the number of label types can be reduced.

[0018]

According to the present invention, the type of label can always be determined accurately. In particular, the present invention can be suitably used for the supply of labels automatically incorporated in a small-quantity, multi-product production line, and for discrimination of labels in a sticking process.
