Description

    The present invention relates to an apparatus and a method for manufacturing a perforated label continuous body, and more particularly to an apparatus and a method for manufacturing a perforated label continuous body in which through holes having an arbitrary shape are formed in an inner region.

Conventionally, a perforated label continuum in which through holes of arbitrary shapes are opened in the inner region of labels of various shapes has been manufactured.
6 is a perspective view of a general annular label continuous body 1 as an example of a perforated label continuous body, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG.
The annular label continuous body 1 has a band-like backing 2 and a plurality of annular labels 3 (perforated labels) temporarily attached to the upper layer side of the backing 2.

    The annular label 3 has a label base 4 and a pressure-sensitive adhesive layer 5 in the lower layer portion, and a circular through hole 3A is formed in the central portion of the inward region. The through hole 2A is also formed in the base 2 at a portion corresponding to the through hole 3A.

FIG. 8 is a schematic cross-sectional view showing essential steps in manufacturing the annular label continuous body 1, and the label base paper 8 is positioned between the male cutting die 6 and the female cutting die 7. As shown in FIG.
The label base paper 8 temporarily adheres the strip-shaped label base material 4 to the strip-shaped base sheet 2 via the adhesive layer 5.

The male punching die 6 has a punching blade 9 and cuts out the label substrate 4 and the adhesive layer 5 together with the backing 2 with the inner punching blade 9A extending to at least the back surface of the backing 2, and the punching holes of the female punching die 7. Remove inner label residue 10 from 7A.
An outer label residue 11 formed by cutting out the label substrate 4 and the pressure-sensitive adhesive layer 5 with an outer extraction blade 9B having a length to the surface of the backing sheet 2 of the extraction blade 9 simultaneously with removal of the inner label residue 10 Are removed (so-called "sludge removal") to produce an annular label 3 with through holes 3A.

However, if the through holes 2A and the like are formed in the backing sheet 2, the stress is concentrated on the through hole 2A portion during the transfer of the annular label continuous body 1 and there is a problem that the negative effects such as the backing sheet are easily generated.
Furthermore, there is a problem that the cost of die cutting becomes high and the cost of mechanically removing the unnecessary portion (inner label waste 10) also becomes high.

In addition, as another manufacturing method of the annular label continuous body 1, there is a method of leaving the inward label waste 10 which is an unnecessary portion as it is, but the range of use of the manufactured annular label continuous body 1 is limited There is a problem that the device may be damaged or it may be inadvertently peeled off from the backing when it is used.
In addition, although illustration is omitted, for example, as the inner label residue, the inner label residue formed by manual cutting without cutting up to the backing sheet 2 (cut out to the label base 4 and the adhesive layer 5, so-called “half removal”) is performed manually. Although there is also a method of removing it from the backing sheet 2 by, etc., there is a problem that a huge processing time is required as the number of manufacturing processes increases.

    As the perforated label continuum, not only so-called annular labels 3 as shown in FIG. 6, but also elliptical labels, triangular or rectangular labels, and labels having any other similar shapes may be used. As for the shape of the through hole formed in the inner region, problems occur, and there are circular, oval, triangular or rectangular shapes as well as other arbitrary shapes, but for the perforated label continuum of these various shapes, There is a demand for a manufacturing apparatus and method that can reliably remove the unnecessary portion (in particular, the inner label residue).

Unexamined-Japanese-Patent No. 1-137287

    The present invention has been made in view of the above problems, and an object of the present invention is to provide an apparatus and a method for producing a perforated label continuous body capable of efficiently producing a perforated label in which through holes are formed.

    Moreover, this invention makes it a subject to provide the manufacturing apparatus and manufacturing method of the perforated label continuous body which can manufacture a perforated label in the state which removed unnecessary parts, such as inner direction label waste, completely.

    Another object of the present invention is to provide an apparatus and a method for producing a perforated label continuum capable of compressing the number of production steps.

    That is, according to the present invention, the adhesive force of the pressure-sensitive adhesive layer is reduced at the bottom surface facing the backing of the inward label waste which is rendered unnecessary as a perforated label, The first invention is an apparatus for manufacturing a perforated label continuum in which the through holes are formed in the inward region, and the label base material is attached to the band-like mount via the pressure-sensitive adhesive layer. In the area of the pressure-sensitive adhesive layer corresponding to the inward area surrounded by the peripheral edge of the through-hole in the thickness direction of the temporarily attached label base paper, a pressure-sensitive adhesive deactivation layer for at least reducing the activity of the pressure-sensitive adhesive layer is formed A punching blade capable of cutting the label substrate and the pressure-sensitive adhesive layer from the label substrate side, and a peeling plate positioned on the lower surface side of the backing sheet downstream of the punching blade; By the blade The inward label substrate in the inward region and the pressure-sensitive adhesive layer can be cut along the outline of the inward region to form an inward label residue, and the inward label residue can be peeled off from the backing sheet by the release plate. The apparatus for manufacturing a perforated label continuous body is characterized in that the perforated label in which the through holes are formed can be left in a temporarily attached state on the backing sheet.

    The second invention is a method of manufacturing a perforated label continuum in which through holes are formed in the inward region, and the thickness of label base paper in which a label base material is temporarily attached to a band-like backing via an adhesive layer. In the pressure-sensitive adhesive layer area corresponding to the inward area surrounded by the peripheral edge of the through-hole in the direction, a pressure-sensitive adhesive deactivation layer that at least reduces the activity of the pressure-sensitive adhesive layer is formed The inner label substrate and the pressure-sensitive adhesive layer in the inward region are cut along the outline of the inward region by the extraction blade capable of cutting the label substrate and the pressure-sensitive adhesive layer, thereby forming the inward label residue The inward label residue is peeled off from the backing sheet by a peeling plate formed on the downstream side of the backing sheet at the downstream side of the punching blade, and the perforated label on which the through holes are formed is temporarily attached on the backing sheet. Let it survive Which is a method for producing a perforated label strip, wherein.

    The inner label residue can make the adhesion to the backing smaller than the adhesion of the perforated label to the backing.

    The adhesive passivation layer may extend slightly outward from the inner region.

    The pressure-sensitive adhesive deactivation layer can be formed by printing the pressure-sensitive adhesive layer.

    The release plate may be capable of deforming a portion of the mount on which the inner label residue is stacked toward the inner label residue.

    A part of the mount on which the inward label residue is laminated may have a turning angle with respect to the release plate smaller than a turning angle with respect to the release plate of the perforated label.

    The release plate may have a step portion that protrudes from the lower surface of the mount to the inner label residue side.

    A turning film having a width equal to the width of the through hole can be attached to the peeling tip of the peeling plate.

    It is possible to provide a suction mechanism capable of suctioning the inward label residue peeled off from the backing sheet by the peeling plate.

    On the downstream side of the peeling plate, a pressing roll can be provided which presses the label base paper from the label base material side toward the mount side.

    The outer label residue of the apertured label and the inner label residue of the apertured label can be sequentially removed from the mount as the label base paper is transferred.

    In the apparatus and method for manufacturing a perforated label continuum according to the present invention, a pressure-sensitive adhesive inactivation layer is formed which at least reduces the activity of the pressure-sensitive adhesive layer corresponding to the inward region surrounded by the periphery of the through-hole The inward label waste is formed in the inward region by the blade, and the inward label waste is peeled off from the backing sheet by the peeling plate, and the perforated label having the through holes is left temporarily attached to the backing sheet. The unnecessary inward label residue can be reliably removed.

    In particular, according to the apparatus for manufacturing a perforated label continuum of the first invention, adhesion inactivation is applied to the area of the pressure-sensitive adhesive layer corresponding to the inward area surrounded by the periphery of the through-hole, at least reducing the activity of the pressure-sensitive adhesive layer. Since the layer is formed, the adhesion of the inward label residue formed by the extraction blade is further reduced, so that it is easy to peel off the backing sheet at the portion of the peeling plate, which can be automatically removed.

    In particular, according to the method for producing a perforated label continuum of the second invention, while the inner label residue in a state in which the adhesive deactivation layer is formed on the pressure-sensitive adhesive layer in the inner region is formed by a punching blade, Since the part is peeled off, the inner label residue can be easily removed from the backing sheet.

FIG. 5 is a schematic side view of an apparatus 20 for manufacturing a perforated label continuum 29 according to an embodiment of the present invention. It is a perspective view which shows the part of the inward label scrap removal part 28 equally. It is a top view of the same and inward label scrap removal part 28. FIG. FIG. 10 is an enlarged side view of the peeling plate 55 and the pressing roll 57 in the same manner. Similarly, FIG. 5A is a schematic side view for explaining the difference in the turning angle of the peeling plate 55, and FIG. 5A slightly exaggerates the case where the step portion 59 corresponding to the turning film 58 is provided, FIG. 5 (2) shows the case where the step part 59 is not provided. It is a perspective view of the general annular ring label continuum 1 as an example of the conventional perforated label continuum. FIG. 7 is a cross-sectional view taken along line VII-VII of FIG. It is a schematic sectional drawing which shows the principal part process at the time of manufacturing the annular | circular shaped label continuous body 1 equally.

    The present invention forms the inward label residue with the punching blade in the adhesive deactivation layer and makes it possible to remove the inner label residue with the release plate, so that the inward label residue can be reliably removed from the backing sheet. We realized the manufacturing equipment and manufacturing method of

Next, an apparatus and a method for producing a perforated label continuous body according to an embodiment of the present invention will be described with reference to FIGS. However, the same reference numerals are given to the same parts as in FIG. 6 to FIG. 8, and the detailed explanation thereof will be omitted.
FIG. 1 is a schematic side view of a manufacturing apparatus 20 for the perforated label continuum 29. The manufacturing apparatus 20 for the perforated label continuum 29 includes a supply unit 21 of the label base paper 8 and a surface printing unit 22; The backing sheet separation unit 23, the back surface printing unit 24, the bonding unit 25, the die cut unit 26, the outward label waste removal unit 27, the inward label waste removal unit 28, and the winding unit 30 of the perforated label continuous body 29 And.
FIG. 2 is a perspective view showing a portion of the inner label scraping portion 28. As shown in FIG.

    As described above, the label base paper 8 temporarily adheres the strip-shaped label base material 4 to the strip-shaped base sheet 2 via the adhesive layer 5, and from the supply unit 21 to the surface printing unit 22 via the guide roller 31. Supply this.

    The surface printing unit 22 includes a surface printing machine 32 and an ultraviolet irradiator 33, and prints predetermined information on the surface side of the label base paper 8 (label base material 4).

    The mounting paper separation unit 23 separates the mounting paper 2 and the laminate 35 of the label base 4 and the pressure-sensitive adhesive layer 5 by the separation roller 34 and can be transported to the respective transfer paths.

The back side printing unit 24 has a back side printing machine 36 and an ultraviolet irradiator 37, and performs printing on a predetermined region of the pressure-sensitive adhesive layer 5 on the back side of the label base paper 8 (laminated body 35).
The predetermined area is an area for forming the inward label residue 51 (described later in FIG. 2).
That is, the predetermined area is an area of the pressure-sensitive adhesive layer 5 corresponding to the inward area 39 surrounded by the periphery of the through hole 38 (FIG. 2) in the thickness direction of the label base paper 8. By printing an optional ink, an adhesive passivation layer 40 (see enlarged portion in FIG. 1) that at least reduces the activity of the pressure-sensitive adhesive layer 5 is formed.
However, due to the formation of the adhesive deactivation layer 40, the inner label residue 51 is not immediately peeled off by the clipping action at the die cutting portion 26 on the downstream side of the label base paper 8 in the transfer direction, and attached to the peripheral device portion. It is necessary to do.
In addition, the adhesiveness of the inner label residue 51 can be optionally selected by selecting the type of printing ink of the adhesive deactivation layer 40 or the printing area thereof, and the printing pattern such as lattice, multi-row or mesh. It can be set.
Note that the adhesion inactivation layer 40 is spread slightly outward from the inner region 39, so that the cutting action in the die cut portion 26 is reliably performed in the region of the adhesion inactivation layer 40. Guarantee that.

    The bonding unit 25 has a bonding roller 41, and is a base 2 separated from the label base paper 8 in the base paper separating unit 23 and guided by the guide rollers 42 and 43, and a laminate 35 subjected to back surface printing. , Are again laminated and laminated, and are supplied to the die cutting portion 26 through the guide rollers 44, 45, 46.

The die cut portion 26 has a die cut roller 47 and an anvil roller 48, and the die cut roller 47 has a punching blade 49 capable of cutting the label substrate 4 and the adhesive layer 5 from the label substrate 4 side.
The extraction blade 49 forms the outer label residue 50 located on the outer side of the perforated label 54 (FIG. 2) in the label base paper 8, and the inner label substrate 4 and the pressure-sensitive adhesive layer 5 in the inner region 39 The inner label residue 51 can be formed on the inner side of the perforated label 54 by cutting along the outline of the inner region 39.
That is, unlike the punching blade 9 (inward punching blade 9A, outward punching blade 9B, FIG. 8) in the conventional male punching die 6, the punching blade 49 forms the outer label waste 50 and the inner label waste 51. Have the same cut length.

    The outer label waste removal portion 27 has a waste removal roller 52 and a waste take-up roller 53, and the waste take-up roller 53 takes up the outer label waste 50 cut out by the removal blade 49.

In particular, as shown in FIG. 2, on the downstream side of the inward label scraping portion 28, the perforated label continuum 29 in which the perforated label 54 is temporarily attached on the backing 2 is manufactured.
The perforated label 54 has the inner label residue 51 removed and has a through hole 38 in the inner region 39 thereof.
That is, the inward label residue removing portion 28 has a peeling plate 55, a suction mechanism 56, and a pressing roll 57.

The peeling plate 55 is located on the lower surface side of the backing 2 at the downstream side of the punching blade 49 of the die cutting portion 26.
The inner label residue 51 is peeled off from the backing 2 by the peeling plate 55, and the perforated label 54 having the through holes 38 formed thereon can be left in a temporarily attached state on the backing 2.

    As described above, since the inner label residue 51 has the adhesive deactivation layer 40 formed on the back side, the adhesiveness to the backing 2 is made smaller than the adhesiveness of the perforated label 54 to the backing 2 There is.

Further, the peeling plate 55 can deform a part of the backing sheet 2 on which the inward label waste 51 is stacked toward the inward label waste 51.
FIG. 3 is a plan view of the inner label residue removing portion 28, and FIG. 4 is an enlarged side view of the peeling plate 55 and the pressing roll 57. As shown in FIG.
In particular, as shown in FIG. 4, a turning film 58 having a width equal to the width of the inward label residue 51 to the through holes 38 is attached to the peeling tip of the peeling plate 55.
By arbitrarily selecting the thickness T of the turning film 58, it is possible to adjust the turning angle of a part of the backing sheet 2 on which the inner label residue 51 is stacked.
That is, due to the step by the diverting film 58, a force to push up locally in the peeling direction acts only on the portion of the inward label waste 51 through the backing sheet 2, and the inward label waste 51 is peeled from the other area of the perforated label 54 I am making it easy.

The position of the through hole 38 in the perforated label 54 is adjusted by adjusting the affixing position of the turning film 58 so as to match the formation position of the through hole 38 of the inner label residue 51 in the width direction of the peeling plate 55 The inner label waste 51 can be peeled off properly.
In addition, by adjusting the width of the turning film 58, it is possible to form a peeling turning portion that matches the backing sheet 2 on which the inward label residue 51 in the through hole 38 in the perforated label 54 is to be stacked.
Of course, by disposing a release plate (not shown) having a width matched to the width and position of the inner label residue 51 without providing the turning film 58 (ie, the inner region 39 or the through hole) By providing this peeling plate only in 38), it is possible to peel and remove only the inner label residue 51 in the same manner as described above.

    In other words, part of the backing sheet 2 on which the inward label waste 51 is laminated has the inward label waste 51 set by making its turning angle with respect to the peeling plate 55 smaller than the turning angle of the perforated label 54 with respect to the peeling plate 55. The main body region portion of the perforated label 54 is prevented from being peeled off from the backing 2 while being easily peeled off.

FIG. 5 is a schematic side view for explaining the difference in the turning angle of the peeling plate 55, and FIG. 5 (1) slightly exaggerates the case where the step portion 59 corresponding to the turning film 58 is provided. FIG. 5 (2) shows the case where the stepped portion 59 is not provided.
That is, as shown in FIG. 5 (1), when the stepped portion 59 or the diverting film 58 is provided, in the peeling plate 55, the stepped portion 59 or the diverting film 58 is inward label waste 51 from the lower surface of the mount 2. It will be projected to the side.
Therefore, the turning angle α of the inward label waste 51 becomes smaller than the turning angle β of the area other than the inward label waste 51 in the perforated label 54 (α <β, in other words, set in a more acute direction). Is easier to peel off.
Further, as shown in FIG. 5 (2), even if the turning angle is the same, the formation of the adhesive deactivation layer 40 on the bottom surface of the inner label residue 51 makes the inner label residue 51 easier to peel from the backing sheet 2 I can do it.
In short, peeling off the inner label residue 51 by arbitrarily selecting the adhesion reduction degree of the inner label residue 51 by the adhesive deactivation layer 40 and the turning angle of a part of the backing sheet 2 on which the inner label residue 51 is laminated. The accuracy can be controlled.

    In addition, it is necessary to synchronize with the transfer of the label base paper 8, but by removing the inner label residue 51 by driving the release plate having the same shape as the inner label residue 51 in the direction of the inner label residue 51 It can also be

The suction mechanism 56 has a suction pipe 60 by vacuum suction, and can suction and remove the inward label residue 51 peeled off from the mount 2 by the peeling plate 55.
Thus, the outer label residue 50 of the perforated label 54 and the inner label residue 51 of the apertured label 54 are sequentially removed from the mount 2 in accordance with the transfer of the label base paper 8.

The pressing roll 57 presses the label base paper 8 from the side of the label base 4 toward the mount 2 on the downstream side of the peeling plate 55.
By selectively adjusting the installation position of the presser roll 57 in the transfer direction of the label base paper 8, it is possible to adjust the turning angle of a part of the mount 2 on which the inner label residue 51 is to be stacked.
Further, as shown by the arrows of virtual lines in FIG. 1, the inner label residue 51 is peeled by controlling the pressing roller 57 to move up and down to contact and separate the perforated label continuum 29 (label base paper 8). The timing of the start and end of the operation can be adjusted. Similarly, the timing can be adjusted by moving the peeling plate 55 up and down as indicated by an arrow of a phantom line.

In the apparatus 20 for producing the perforated label continuous body 29 having such a configuration, in particular, as described above, in the inner label residue removing portion 28, the adhesive of the inner label residue 51 corresponding to the inner region 39 surrounded by the periphery of the through hole 38 In the area of the layer 5, the adhesive deactivation layer 40 is formed in the back surface printing unit 24.
In the die cut portion 26, the inward label substrate 4 and the adhesive layer 5 in the inward region 39 are cut along the outline of the inward region 39 by the punching blade 49 to form an inward label residue 51, and In the inward label scrap removing portion 28, only the inward label residue 51 is peeled off from the backing sheet 2 by the peeling plate 55 positioned on the lower surface side of the backing sheet 2, and the perforated label 54 in which the through holes 38 are formed is provisionally placed on the backing sheet 2. Since the inner label residue 51 is left in the worn state, the inner label residue 51 is reliably peeled off from the backing sheet 2 without opening the through holes 2A (FIG. 7) and the like in the backing sheet 2 as before (i.e. The perforated label continuum 29 can be manufactured stably without causing paper breakage and the like.
The apertured label continuum 29 thus produced is wound up by its winding section 30 (FIG. 1).

The inward label residue removing portion 28 may be provided on the downstream side of the die cutting portion 26 and on the upstream side of the outer label residue removing portion 27.
Further, when the outer label waste 50 is not formed as a perforated label, the outer label waste removing portion 27 does not have to be provided.
