Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a label co-up prevention device, and more particularly, a label co-up that can suppress the co-up of a label by maintaining adhesion between the label and the base sheet when an unnecessary portion is peeled off from the base sheet. The present invention relates to improvement of the prevention device.
[0002]
[Prior art]
Conventionally, when a large number of labels are formed, a technique of cutting a label sheet into a large number of closed loops using a die cutting device is known. This label sheet is bonded to a base sheet made of a strip-shaped release paper via an adhesive layer. Unnecessary parts located outside each label are peeled off from the base sheet via an unnecessary part collecting device, The label is transferred to the next process as a state where only the label is adhered.
[0003]
However, in such an unnecessary part collecting apparatus, when the unnecessary part is peeled off, the label is peeled off from the base sheet together with the unnecessary part, so-called a phenomenon of rising together occurs, and the yield of the label is lowered. There is an inconvenience. This is because the label and the adhesive layer of the unnecessary part are bonded to each other after the cutting by the die-cutting device, or the outer peripheral edge of the label and the inner peripheral edge of the unnecessary part are caught when the unnecessary part is peeled off.
[0004]
By the way, as a technique for preventing co-up of labels, there is a method disclosed in Japanese Patent Publication No. 7-37088. In this publication, a technique is adopted in which compressed air is blown onto the label and the label is pressed against the base sheet when the unnecessary portion is peeled off.

Japanese Examined Patent Publication No. 7-37088 [0006]
[Problems to be solved by the invention]
However, in the method disclosed in Japanese Patent Publication No. 7-37088, compressed air is blown, so that not only the structure is complicated by a compressor, a nozzle, etc., but also the inconvenience that the whole apparatus is increased in size. Moreover, in addition to requiring maintenance of the compressor, it is necessary to supply power for operating the compressor, resulting in inconvenience that it is difficult to reduce the manufacturing cost. Moreover, since the co-raising of the label is suppressed using gas, a pressing force cannot be sufficiently applied to the label, which is not sufficient to prevent the co-raising. Therefore, a method for preventing the co-up with further improved reliability has been desired.
[0007]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and the object of the present invention is to easily suppress the co-raising of labels with a simple structure and to peel off unnecessary portions with a high yield. It is an object of the present invention to provide a label co-up prevention device that can realize the above.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention forms a plurality of closed loop labels by forming notches in a label sheet laminated on a strip-shaped base sheet via a predetermined adhesive layer, and the label, the base sheet, The label co-up prevention device when peeling from the base sheet as an unnecessary part, the area located outside each label while maintaining the adhesion of,
A blade capable of folding the unnecessary portion;
A piece member whose tip protrudes in the feed direction of the base sheet from the folded end of the blade,
When the unnecessary part is peeled from the base sheet with the blade, the tip of the one member contacts the label and presses the label against the base sheet. According to such a configuration, since a pressing force can be directly applied to the label using a single member, it is possible to effectively and reliably suppress the co-raising of the label with a simple structure, and consequently, the yield of label manufacturing. As a result, the cost of the product can be reduced. In addition, since compressed air as shown in the conventional example is not used, not only can the reliability of prevention of co-up rise be improved, but also the device can be reduced in size and the power for operating the device is also necessary. And not.
[0009]
Moreover, the structure that the said piece member is provided for every row | line | column of the label in alignment with the feed direction of a label sheet | seat can also be employ | adopted. With this configuration, even a label sheet in which a plurality of labels are formed can be applied to an apparatus that mass-produces labels that can prevent the labels in each column from rising together.
[0010]
Furthermore, it is preferable that the piece member has a configuration in which the tip position thereof can be adjusted. According to such a configuration, when the formation position and shape of the label change, or even if the base sheet feed direction is a different type of label manufacturing machine, it can easily cope with this, It is possible to appropriately adjust the pressing force of the single member against the label.
[0011]
In the present specification, the term “closed loop” is used for a shape in which outer peripheral edges forming a label are continuously surrounded by a series, such as a square, a rectangle, a circle, an ellipse, and an oval.

A roller 12 around which the belt-like sheet S is wound, a blade 13 acting as a folding guide extending substantially parallel to the axial direction of the roller 12, and a label co-up prevention device installed between the blade 13 and the roller 12 15 and an unnecessary portion take-up roll (not shown) that winds up an unnecessary portion, which will be described later, of the belt-like sheet S, and is positioned above the roller 12.
[0014]
The belt-like sheet S includes a base sheet S1 made of release paper and a label sheet S3 laminated on the base sheet S1 via a predetermined adhesive layer S2 (see FIG. 3). In the present embodiment, in the surface of the label sheet S3, a plurality of labels L having a substantially oval shape that is horizontally long in a plan view are formed in three rows along the feed direction of the label sheet S3 (the arrow X direction in FIG. 3). ing. Each label L is formed by cutting the label sheet S3 and the adhesive layer S2 using an upstream die cutting device (not shown). Here, an area located outside each label L in the label sheet S3 and the adhesive layer S2, that is, an area other than the label L in the label sheet S3 and the adhesive layer S2 is defined as an unnecessary part E.
[0015]
The blade 13 is formed to have a substantially triangular shape in cross section (see FIG. 3) and is supported so as to straddle the frames 11 and 11 via shaft members 13A at both ends in the longitudinal direction. The lower end portion of the blade 13 in the drawing is disposed at a position slightly away from the outer peripheral surface of the roller 12, and is provided so that an unnecessary portion E of the label sheet S 3 wound around the roller 12 can be folded upward.
[0016]
The label co-up prevention device 15 is attached to the inner surface side of each frame 11, 11 at a position above the roller 12 via a spacer 17, and has a pair of support plates 18, 18 having slot holes 18 A in the surface. In addition, a prismatic extending member 19 extending between the support plates 18 and 18 and three elongated piece members 20 extending between the extending member 19 and the blade 13 are configured. Bolts 22 and 22 that are screwed into both longitudinal ends of the passing member 19 are inserted into the slot holes 18A and 18A, so that the passing member 19 can move along the extending direction of the slot hole 18A. It is like that. Further, the handing member 19 includes a plurality of screw holes 19A formed at predetermined intervals along the longitudinal direction.
[0017]
The piece member 20 is disposed for each row of labels L along the feeding direction of the belt-like sheet S, and is provided in a direction substantially parallel to the tangential direction of the roller 12. The tip end side (lower end side in FIG. 2) of the piece member 20 is provided at a position that contacts the label L in the vicinity of the peeling position of the unnecessary portion E and protrudes in the feed direction of the base sheet S1 from the folded end of the blade 13, that is, the lower end.

In the above configuration, when the unnecessary portion E is peeled from the base sheet S 1, first, the belt-like sheet S is set between the roll 12 and the blade 13, and the belt-like sheet S is wound around the roll 12. Next, the unnecessary portion E located on the lead end side of the belt-like sheet S is forcibly peeled and attached to an unnecessary portion winding roll (not shown), and the unnecessary portion E is folded back at the lower end position of the blade 13. And while sending the strip | belt-shaped sheet | seat S to the arrow X direction in FIG. 3, the said unnecessary part winding roll is rotated to a predetermined direction, the unnecessary part E is peeled from the base sheet S1, and it winds up to an unnecessary part winding roll. Thus, only the label L is adhered on the base sheet S1. At this time, the tip side of the piece member 20 contacts the label L in the vicinity of the peeling position of the unnecessary portion E and presses the label L against the base sheet S1, so that the label L peels from the base sheet S1 together with the unnecessary portion E. So-called co-up is prevented.
[0019]
When adjusting the tip position of the piece member 20, the bolt 22 that supports the passing member 19 is loosened, moved along the slot hole 18 </ b> A of the support plate 18, and tightened to retighten the bolt 22. Adjustment of the front-end | tip position of the piece member 20 along the left-right direction in FIG. 3 is performed. Furthermore, the position adjustment along the tangential direction of the roll 12 in the piece member 20 can also be performed. In this case, the piece member 20 is extended to the slot hole 20A with the bolt 23 in the slot hole 20A of the piece member 20 loosened. The bolt 23 is retightened by moving along the exit direction.
[0020]
Therefore, according to such an embodiment, since the piece member 20 that contacts the label L in the vicinity of the peeling position of the unnecessary portion E is provided, when the unnecessary portion E is peeled, the inner peripheral edge of the unnecessary portion E and the outer peripheral edge of the label L Can be prevented and the label L can be prevented from rising together with the unnecessary portion E. In addition, since the support plate 18 and the piece member 20 are provided with slot holes 18A and 20A so that not only the piece member 20 but also the passing member 19 can be moved, the position adjustment in two different directions can be performed. It is possible to smoothly adjust the pressing force of the one-piece member 20 against L.
