Description

    The present invention relates to a label continuum, a processing apparatus thereof, and a processing method thereof, and in particular, a label continuum having a structure in which a label base material is temporarily attached to a strip-shaped release paper via an adhesive layer, a processing apparatus thereof, and a processing thereof It is about the method.

The conventional label continuum will be outlined with reference to FIGS.
FIG. 3 is a cross-sectional view of a general label continuum 1. The label continuum 1 includes a strip-shaped release paper 2 (mounting paper), an adhesive layer 3 laminated on the release paper 2, and the adhesive. And a label substrate 4 laminated on the release paper 2 via the layer 3.
In general, the label base material 4 and the pressure-sensitive adhesive layer 3 are cut in the stacking direction as shown in the figure with respect to the pressure-sensitive adhesive base paper composed of the release paper 2, the pressure-sensitive adhesive layer 3 and the label base material 4. Thus, a plurality of label pieces 5 composed of the label substrate 4 and the pressure-sensitive adhesive layer 3 are formed, and the plurality of label pieces 5 are temporarily attached onto the release paper 2 via the pressure-sensitive adhesive layer 3.
A position detection mark 6 is printed in advance on the back side of the release paper 2.

When the label continuous body 1 having such a configuration is loaded into the automatic label pasting machine 7 and an automatic pasting operation is performed, there are the following problems.
FIG. 4 is a schematic side view of the automatic label applicator 7. The automatic label applicator 7 includes a supply unit 8, a detection unit 9, a printing unit 10, a peeling unit 11, and a peeling unit. The paper winding unit 12, the pasting unit 13, and the article conveying unit 14 are included.

    The supply unit 8 winds and holds the strip-shaped label continuous body 1 in a roll shape, and enables the label continuous body 1 to be fed out in a strip shape.

    The detection unit 9 includes a position detection sensor 15. The position detection sensor 15 detects the position detection mark 6 of the label continuous body 1, and the printing unit 10 or the peeling unit 11 of the label continuous body 1 (label piece 5). The relative position to can be detected.

    The printing unit 10 can print predetermined information (variable information) on the label piece 5 of the label continuous body 1 by an arbitrary printing method. If necessary information (fixed information) is printed on the label piece 5 in advance and variable information is unnecessary, the printing unit 10 is not required.

    The peeling part 11 has a peeling pin 16, and the peeling pin 16 turns only the peeling paper 2 in the direction of the peeling paper winding part 12 so that the label piece 5 can be peeled from the peeling paper 2.

    The release paper take-up unit 12 winds the release paper 2 turned at the release pin 16 of the release unit 11 at a predetermined pitch.

    The affixing unit 13 has a label aspirator 17 that sucks the peeled label piece 5 and reciprocates in the direction of the article M (object to be adhered) so that the label piece 5 can be affixed to the surface thereof. .

The article transport unit 14 includes, for example, a belt conveyor 18 that moves in a direction perpendicular to the paper surface, and transports the article M to a position below the pasting unit 13.
The article conveying unit 14 may be a belt conveyor that moves in the direction in which the label continuous body 1 is transferred (from left to right in FIG. 4). Instead of the label suction unit 17, a label pressing roller (see FIG. (Not shown) may be provided, and the peeled label piece 5 may be pressed against the article M conveyed to the lower position.

    In the automatic label sticking machine 7 of the automatic sticking method as described above, it is essential that the label piece 5 is peeled off from the release paper 2 reliably and stably, and the peeling property that the label piece 5 peels from the release paper 2. When (peeling force) is strong, there is a possibility that the label piece 5 may not be peeled from the release paper 2 in the peeling part 11, and there is a problem that it is difficult to expect stable automatic sticking.

Thus, the peeling force is determined in the production stage of the adhesive base paper by the characteristics of the label base 4, the adhesive characteristics of the adhesive layer 3, the release characteristics of the release paper 2, etc. In some cases, it is practically difficult to obtain an adhesive base paper (label continuous body 1) having a peeling force that perfectly suits each automatic label applicator 7 while it is difficult to control or prepare the peeling force. It is.
That is, as for the peeling property (peeling force) of the continuous label 1, the value is given a predetermined width at present, but of course there are structural differences due to the individual automatic label applicators 7. There is a problem that the label piece 5 may not be properly peeled off from the release paper 2 due to temperature, humidity, etc. at the use site.
Accordingly, the label continuum 1 having an incompatible peeling force may be inevitably discarded, which causes a problem from the viewpoint of resource saving and also causes a cost increase.

Next, the label continuum 20, the processing device 21 and the processing method thereof according to the embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 3 and 4 are denoted by the same reference numerals, and detailed description thereof will be omitted.
FIG. 1 is a schematic perspective view of the label continuum 20 and its processing device 21, and FIG. 2 is a longitudinal sectional view of the label continuum 20.
The label continuous body 20 was laminated on the release paper 2 via the adhesive layer 3 and the strip-shaped release paper 2, the adhesive layer 3 laminated on the release paper 2, similarly to the label continuous body 1 described above. And a plurality of label pieces 5 composed of the label base material 4 and the pressure-sensitive adhesive layer 3 by cutting the label base material 4 and the pressure-sensitive adhesive layer 3 in the stacking direction. The plurality of label pieces 5 are temporarily attached onto the release paper 2 via the adhesive layer 3.
However, the processing device 21 forms the concavo-convex portion 22 on the surface of the release paper 2 on the pressure-sensitive adhesive layer 3 side of the label continuum 20.

As shown in FIG. 1, the processing apparatus 21 includes a peeling portion 23, a concavo-convex forming portion 24, and a re-tempering portion 25.
In addition, as a supply form of the label continuous body 1 to the processing apparatus 21, a form in which the label continuous body 1 in a state in which the label piece 5 is formed is loaded in a rolled state, or the label piece 5 is not yet formed. It is possible to adopt an arbitrary form such as a form in which the adhesive strip is loaded as it is, and a cut portion (not shown) is provided upstream of the peeling portion 23 to form the label piece 5 and then supplied to the peeling portion 23. . Further, regarding the printing unit 10 (FIG. 4), it is optional whether to provide this on the upstream side or downstream side of the peeling unit 23 or not to provide it.

    The peeling unit 23 includes a peeling roller 26, and the peeling roller 26 turns only the peeling paper 2 to peel the label piece 5 from the peeling paper 2.

The concavo-convex forming portion 24 is provided on a release paper detour 27 formed between the release portion 23 and the re-attachment portion 25, and is applied to the surface side of the release paper 2 (adhesive layer 3 side). It has the processing roller 28 and the rubber roller 29 which contacts the back surface side of the release paper 2.
The release paper detour 27 is a detour that can transfer the release paper 2 from which the label pieces 5 have been separated to the re-tacking unit 25 by detouring between the peeling unit 23 and the re-tacking unit 25.
The embossing roller 28 is formed by uniformly dispersing protrusions 28A having an arbitrary shape on the peripheral surface thereof, and peeling is performed by pressure-transferring the release paper 2 between the rubber roller 29 and a predetermined pressure. The uneven portion 22 can be formed on the paper 2. Therefore, the concavo-convex portions 22 (in FIG. 2, the concave portions 22A and the convex portions 22B) of the release paper 2 are uniformly dispersed on the surface of the release paper 2.

    The shape, size, and density of the protruding portion 28A are arbitrary. As the shape, it is possible to adopt a shape as required, such as a triangular cross section, a trapezoidal shape, a quadrangular shape, or a semicircular shape.

The interval is such that the transfer paper 2 on the side can be transferred to the release paper 2 on the re-tempering roller 30 side.

In particular, as shown in FIG. 2, a gap 31 is formed between the release paper 2 and the pressure-sensitive adhesive layer 3 by forming the uneven portion 22 in the release paper 2.
Therefore, by adjusting the density of the concavo-convex portions 22 in the release paper 2, the contact area of the pressure-sensitive adhesive layer 3 to the release paper 2 can be adjusted, and the peeling force of the label piece 5 from the release paper 2 can be adjusted. .
Moreover, the peeling force from the release paper 2 of the label piece 5 is adjusted by selecting the characteristics of the label substrate 4, the adhesive characteristics of the adhesive layer 3, the release characteristics of the release paper 2, and the density of the concavo-convex portion 22. Can be possible.

    In the processing apparatus 21 having such a configuration, the label piece 5 is peeled off from the release paper 2 by turning only the release paper 2 in the peeling portion 23 of the loaded label continuous body 1 and the release paper 2 from which the label piece 5 has been peeled off. Is transferred to the release paper bypass circuit 27, and the uneven portion 22 is formed on the release paper 2 in the uneven portion forming section 24 of the release paper bypass route 27, and the release paper 2 on which the uneven portion 22 is formed is disposed downstream of the release portion 23. In the temporary reattachment portion 25 located at, the label piece 5 can be temporarily attached again to form the continuous label body 20 according to the present invention.

    Thus, even if it is the label continuous body 1 which has a peeling characteristic within a predetermined high level range, it is allowed to pass between the pressure-sensitive adhesive layer 3 and the release paper 2 by passing it through the concavo-convex forming portion 24 in the processing device 21. By reducing the contact area and reducing the peeling force, it is possible to peel the label piece 5 from the release paper 2 stably and reliably even if it is loaded in the automatic label applicator 7 (FIG. 4).

    Further, since the label piece 5 is easily peeled from the release paper 2, not only automatic sticking but also when the operator peels the label piece 5 with a finger and performs a manual sticking operation, It can be done smoothly.
