Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for producing a printed label, and more particularly, to a method for directly performing printing on a pressure-sensitive adhesive surface of a label substrate and performing printing in a series of steps. The present invention relates to a printing label manufacturing apparatus and a manufacturing method thereof capable of manufacturing a label.

[0002]

2. Description of the Related Art Heretofore, there has been known a print label in which predetermined printing is performed on a resinous film that can be attached to various adherends such as a box. As the conventional structure of this print label, an adhesive is provided on both sides of the base such as paper and film, and a release film is attached to the surface of one adhesive,
A configuration is adopted in which printing is performed on the surface of the other adhesive by an ink jet printer, and a transparent laminate film is attached to the surface (for example, Japanese Utility Model Application Laid-Open No. 3-31).
776).

[0003] When the print label is attached to the adherend, the release film in the direction opposite to the printing is peeled off from the base, and the adhesive appearing on the surface is adhered to the adherend. Therefore, since the printed characters, symbols, and the like are covered with the laminate film, it is possible to effectively avoid peeling of the print after being attached to the adherend, and it is possible to maintain a stable display effect.

However, the above-mentioned print label has a base, an adhesive provided on each of both sides of the base, and a laminate film in an attached state, and constitutes the entire print label. The number of layers becomes a multilayer structure of four layers, and therefore, the number of manufacturing steps of the print label inevitably increases, and
There is a disadvantage that the production cost of the printed label is increased.

Further, according to the print label having a multilayer structure as described above, there is naturally a limit in reducing the thickness of the print label as a whole. Therefore, when the print label is attached to the adherend, a certain level difference exists between the surface of the laminate film and the adherend surface, and the print label is inadvertent due to the adhesive strength of the adhesive. There is also a disadvantage that it is easily peeled off.

Accordingly, the present inventor has made it possible to greatly reduce the number of layers of a printed label while simplifying the structure while effectively maintaining the existing effect of preventing the printed characters and symbols from being peeled and stained. (Japanese Patent Application No. Hei 6-2421) has proposed a print label that can reduce the manufacturing cost.
No. 29).

According to the above-mentioned proposed printing label, the number of label layers can be reduced and the production efficiency can be dramatically improved.
In particular, it could be suitable for application to a distribution system or the like.

[0008]

However, the print label is intended to be a label in which a large number of label substrates used as a raw material are continuously attached at regular intervals in the longitudinal direction of a release sheet. This is based on the premise that it is necessary to previously form a label base material corresponding to the size at the time of sticking to the adherend. In addition, immediately after the production of the print label, although it is suitable for sticking it to a predetermined adherend,
This method is not suitable for a case where only a print label is manufactured and a time-dependent operation of attaching the print label to an adherend in another step is performed.

[0009]

Further, in the printing label manufacturing apparatus according to the present invention, the release sheet peeled from the label substrate is attached to a printing surface side of the label substrate printed by the non-contact printing device. Configuration can be adopted.

Further, the label manufacturing method according to the present invention uses a raw material obtained by attaching a release sheet to a label substrate via an adhesive, and leaves the adhesive on the label substrate side to remove the adhesive from the release sheet. A method is adopted in which a label is obtained by printing with a non-contact printing device on the pressure-sensitive adhesive surface while feeding the label base material in a predetermined direction after peeling.

In the above manufacturing method, a method is also adopted in which the release sheet peeled from the label substrate is attached to the printing surface side of the label substrate printed by the non-contact printing device. can do.

[0015]

The raw material for producing a printed label is a material in which a release sheet is adhered to one surface of a label base material which is continuous in a band shape via an adhesive. The release sheet is peeled off from the raw material while leaving the pressure-sensitive adhesive on the label substrate side during the delivery. The label substrate after the release sheet has been peeled is printed on the adhesive surface by a non-contact printing device in the process of being sent out by the sending device, thereby forming a print label. This print label can be attached with the pressure-sensitive adhesive surface facing the adherend, and in the attached state, the print surface is sandwiched between the label base material and the adherend, and the character To prevent rubbing and staining.

The configuration in which the release sheet peeled off from the label substrate is adhered to the printing surface side of the label substrate printed by a non-contact printing device enables storage or the like without immediately attaching to the adherend. Become.

The print label according to the present invention can be suitably applied to a label composed of characters, symbols, and the like for indicating the source or quality, and also as a print label such as a bar code for a POS system. Also, when peeling off the label, the adhesive is distorted, or the tamper-proof label can be seen to have been opened by the cracking of the adhesive layer, or the printing surface and the adhesive surface and a special method It can also be used as a tamper-proof label or the like for which a fake label cannot be easily produced.

Further, as the label base material in the present invention, it is preferable to employ a material having translucency.
In a mode in which the printing surface is exposed through the adherend, an opaque label substrate may be used.

Further, the transmission of each driving force such as the transmission device 20 in the present invention is not limited to the illustrated configuration example, and the same operation can be performed even if various design changes are made. .

Although the non-contact printing device 23 has been described using an ink jet printer, the same operation and effect as described above can be obtained even if another printing device is employed. For example, in addition to an ink jet printer, a laser printer or the like that can perform printing by directly irradiating a laser beam to the adhesive surface may be employed.

Further, in the above-described embodiment, the case where the pressure-sensitive adhesive surface is on the lower surface side is illustrated and described as the posture for sending out the label base material 19, but the present invention is not limited to this, and
May be adopted in such a manner that the surface is oriented in the vertical direction, and the non-contact printing device 23 may be used for printing in the process.

In the above embodiment, the second die cutting device is arranged between the first die cutting device 27 and the label winding device 32.
