Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method and an apparatus for manufacturing a label continuum, and more particularly to a method and an apparatus for manufacturing a label continuum in which label pieces are temporarily attached to a belt-like mount at a predetermined interval.
[0002]
[Prior art]
The label continuum is obtained by temporarily attaching label pieces to a belt-like mount at a predetermined interval, and is conventionally manufactured as follows. First, a composite label base paper is prepared in which a strip label, which is a raw material of a label piece, is temporarily attached to a strip mount. Subsequently, a die-cutting blade is pressed against the strip-shaped label of the composite label base paper to die-cut label pieces having a predetermined shape at predetermined intervals. Then, unnecessary ridge portions around the punched label piece are peeled off from the belt-like mount. As a result, a continuous label body in which the label pieces are temporarily attached to the belt-like mount at a predetermined interval is manufactured.
[0003]
[Problems to be solved by the invention]
However, the label continuum manufactured by the conventional label continuum manufacturing method is used when the label strip is automatically pasted by the label automatic pasting apparatus that strips and peels the label strip from the strip mount by transporting the strip mount by the peeling plate. Furthermore, there is a drawback that the label piece is difficult to peel off from the belt-like mount. In other words, if the punching depth is too shallow, the label pieces will be peeled off together when the heel part is scraped off, so that the punching is performed deeper. However, if the punching depth is too deep, the punched label This is because the periphery of the piece bites into the belt-like backing sheet together with the glue of the glue layer formed on the back surface of the belt-like label, so that the label strip is temporarily transported while being temporarily attached to the belt-like backing sheet on the release plate.
[0004]
As a solution to such peeling failure and sticking failure in such an automatic label sticking device, a method called peel-end is conceivable. This method is a method in which the die-cut label piece is first peeled off from the strip-shaped mount, and then this label strip is moved from the original die-cutting position to a predetermined position and then reattached to the strip-shaped mount. When this method is used, even when the punching depth is deep, once the label piece is peeled off, the periphery of the label piece is not held by glue, and the label piece can be easily peeled off from the belt-like mount. is there. However, there is a disadvantage that this method cannot be applied when the pitch between the label pieces is short, or when a thin strip label of, for example, 50 μm or less is used.
[0005]
This invention is made in view of such a situation, and when manufacturing a label continuous body, providing the manufacturing method and apparatus of a label continuous body from which a label piece can peel easily from a strip | belt-shaped mount. Objective.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a method for producing a continuous label body in which label strips are temporarily attached to a strip mount at a predetermined interval. A method for producing a continuous label body in which a composite base paper that has been attached is die-cut from the side of the strip-shaped label with a die-cutting blade, and the ridge portion of an unnecessary strip-shaped label around the punched label piece is peeled off from the strip-shaped mount In this embodiment, the die-cutting depth of the die-cutting blade is characterized in that a peeling start side for peeling the label piece from the strip-shaped mount is shallow and a peeling end side is deepened.
[0007]
In order to achieve the above object, the present invention provides a continuous label manufacturing apparatus in which label pieces are temporarily attached to a belt-like mount at a predetermined interval, and is a belt-like label that is an original fabric of the label pieces on the belt-like mount. Of the label continuous body, in which the composite label base paper temporarily attached with a die is punched from the side of the strip-shaped label with a die-cutting blade, and the wrinkles of unnecessary strip-shaped labels around the punched label piece are peeled off from the strip-shaped mount In the manufacturing apparatus, the die cutting blade has a holding portion that supports the blade, and the protrusion amount of the blade with respect to the blade holding surface of the holding portion is small on the peeling start side for peeling off the label piece from the belt-like mount, and peeling is performed. The end side is formed large.
[0008]
According to the present invention, when the label piece is peeled off from the belt-like mount, the punching depth on the peeling start side is shallow and the peeling end side is deepened. As a result, when the strip mount is turned and conveyed by the peeling plate of the automatic label sticking device, the peeling start side of the label piece, that is, the front side in the carrying direction of the strip mount is easily peeled off. It is possible to prevent the problem of not being performed. In addition, since the die-cutting depth on the peeling end side of the label piece is deep, the label piece does not fall off from the belt-like mount during the conveyance of the label continuous body.

[0012]
A composite label base paper 22 wound in a roll is set on the composite label base paper supply reel 12. This composite label base paper 22 is temporarily attached to a belt-like mount 24 having a release layer made of silicon or the like formed on the surface thereof, and a belt-like label 26 having a glue layer formed on the back side (band-like mount side). It is wound to form a roll. Then, the composite label base paper 22 fed out from the composite label base paper supply reel 12 is guided to the die cutting device 14 via the guide roller 28.
[0013]
The die cutting device 14 includes a die cutting blade 30 and a support base 32 that supports the composite label base paper 22 when the composite label base paper 22 is punched by the die cutting blade 30. As the die cutting blade 30, a flat blade type or a rotary blade type can be preferably used (in addition, a flat blade type punch blade is shown in FIG. 1).
[0014]
FIG. 2 is a view for explaining a flat blade type of the die cutting blade 30, (a) is a bottom view, and (b) is a side view. As shown in these drawings, a flat cutting blade type die cutting blade 30 is formed of a rectangular shape with a U-shaped shallow cutting blade 30A and a U-shaped deep cutting blade 30B held by a blade holding portion 34. The blade 30 is formed to be fixed to the fixing member 31. Further, the shallow punching blade 30 </ b> A is formed so as to have a small projection amount with respect to the holding surface 34 </ b> A of the blade holding portion 34, and the release start side when the label piece 36 is peeled from the belt-like mount 24 is punched out. Further, the deep cutting blade 30B is formed to have a large projection amount with respect to the holding surface 34A, and the peeling end side when the label piece 36 is peeled from the belt-like mount 24 is punched. The difference in protrusion amount between the peeling start side and the peeling end side of the flat blade 30 is, for example, about 30 μm, the thickness of the blade 30 is about 1 mm, and the width of the blade edge of the blade 30 is about 0.02 to 0.03 mm. 34 is made of, for example, resin, and its thickness can be about 12 mm. When the belt-like label 26 side of the composite label base paper 22 conveyed by this flat-blade type die-cutting blade 30 is pressed, the belt-like label 26 is die-cut into label pieces 36, 36,. The mold release depth on the peeling start side of the label piece 36 temporarily attached to the belt-like mount 24 is shallow, and the mold release depth on the peeling end side is deep.
[0015]
FIG. 3 shows another aspect in which the die cutting depth is changed between the peeling start side and the peeling end side in the flat cutting blade type die cutting blade 30, FIG. 3 (a) is a bottom view, and FIG. 3 (b). Is a side view. As shown in these drawings, the die cutting blade 30 is formed by a single rectangular blade 30, but the blade holding portion 34 is changed by changing the polishing amount of the blade 30 between the peeling start side and the peeling end side. The protrusion amount of the blade 30 with respect to the holding surface 34A is formed so as to increase as it moves from the peeling start side where the label piece 36 is peeled off from the belt-like mount 24 to the peeling end side.
[0016]
FIG. 4 shows still another method for changing the die-cutting depth between the peeling start side and the peeling end side in the flat-blade type die-cutting blade 30. In this method, the amount of protrusion is the same on the peeling start side and the peeling end side of the blade 30 with respect to the holding surface 34A, and a PET film of about 30 μm is provided between the blade holding part 34 and the fixing member 31 on the peeling end side. The blade 30 is inclined by adhering it to the fixing member 31 with an adhesive 37 across 33. Thereby, the punching depth on the peeling start side of the label piece 36 temporarily attached to the belt-like mount 24 is shallow, and the punching depth on the peeling end side becomes deep.
[0017]
FIG. 5 is a side view of the rotary blade 30 type of the die cutting blade 30. Four square-shaped blades 30 are formed on the peripheral surface of the blade holding portion 34 on the peripheral surface of the cylindrical blade holding portion 34. The square blades 30 are supported at equal intervals in a curved state along the same direction, and the projection amount of the blades 30 with respect to the holding surface 34A of the blade holding part 34 is the same as in FIGS. 36 is formed so as to increase as it moves from the peeling start side for peeling 36 from the strip mount 24 to the peeling end side. A support roller 35 is provided opposite the rotary blade 30. Thereby, the punching depth on the peeling start side of the label piece 36 temporarily attached to the belt-like mount 24 is shallow, and the punching depth on the peeling end side becomes deep.
[0018]
The composite label base paper 22 that has been die-cut by the die-cutting device 14 is guided to the take-up roll device 16.
[0019]
The take-up roll device 16 is composed of a pair of rolls 38 and 38 that sandwich the band-shaped mount 24 and the band-shaped label 26 that are bonded together. By this take-up roll device 16, the unnecessary label stick 40 around the label piece 36 is removed, and the label stick 40 is taken up by the label pick-up reel 18.
[0020]
The composite label base paper 22 fed out from the composite label base paper supply reel 12 is transported through each part of the die cutting device 14 and the take-up roll device 16, and then a plurality of label pieces 36, 36,. The label continuous body 42 is temporarily attached at intervals.
[0021]
The produced label continuous body 42 is then wound up in a roll shape on the label continuous body take-up reel 20.
[0022]
Next, the operation of the continuous label manufacturing apparatus 10 of the present embodiment configured as described above will be described.
[0023]
First, the composite label base paper 22 is fed out from the composite label base paper supply reel 12 and guided to the die cutting device 14 through the guide roller 28. Subsequently, in the die cutting device 14, die cutting is performed by the flat blade 30 or the rotary blade 30 having the above-described structure. Thereby, the die-cutting process is performed so that the die-cutting depth on the peeling start side of the label piece 36 temporarily attached to the belt-like mount 24 is shallow and the die-cutting depth on the peeling end side is deep. This die cutting process is performed at a predetermined interval on the traveling composite label base paper 22. The composite label base paper 22 from which the label pieces 36, 36,... Have been die-cut is then removed by the take-off roll device 16 from the unnecessary label wrinkles 40 around the label pieces 36. The label bag 40 is taken up by the label bag take-up reel 18. After the label bag 40 is removed, the label continuous body 42 is obtained by temporarily attaching the label pieces 36, 36,... Thereafter, the label continuous body 42 is wound around the label continuous body winding reel 20.
[0024]
The label continuous body 42 manufactured in this way is suitable for the automatic label pasting apparatus 60 that automatically peels the label piece 36 from the strip-shaped mount 24 and sticks it to the article 58 to be pasted.
[0025]
FIG. 6 is a schematic diagram showing the overall structure of the automatic label pasting apparatus 60.
[0026]
As shown in the figure, the label automatic pasting device 60 is mainly composed of a supply reel 44 and a take-up reel 56 of the label continuous body 42, a printing unit 46, a peeling plate 48, and a suction plate 50.
[0027]
On the supply reel 44, the label continuous body 42 is wound and mounted in a roll shape. The label continuous body 42 is sent out from the supply reel 44 by rotating the platen roller 52 of the printing unit 46 and supplied to the printing unit 46.
[0028]
The printing unit 46 is composed of a thermal head 54 and a platen roller 52 that are arranged to face each other. Based on printing data output from a control device (not shown), each label piece 36, 36,. Etc. are printed. The printed label piece 36 is sent to the peeling plate 48 together with the belt-like mount 24.
[0029]
The peeling plate 48 has a leading end (an end on the suction plate 50 side) formed at an acute angle, the label continuous body 42 is hung on the leading end, and the belt-like mount 24 is wound around the take-up reel 56. Accordingly, since the belt-like mount 24 is turned by the peeling plate 48, the label piece 36 having a rigidity higher than that of the belt-like mount 24 is peeled from the belt-like mount 24. In the peeling of the label piece 36 by the peeling plate 48, the label continuous body 42 has a mold release depth on the peeling start side when peeling the label piece 36 from the belt-like mount 24, that is, on the front side in the transport direction of the label continuous body 42. It is shallow and formed so that the end of peeling is deep. As a result, when the strip-shaped mount 24 is turned and conveyed by the peeling plate 48, the peeling start side of the label piece 36 is easily peeled off, so that it is possible to prevent a problem that the label piece 36 is not peeled off from the strip-shaped mount 24 even after turning and transporting. In addition, since the die-cutting depth on the peeling end side of the label piece 36 is deep, the label piece 36 does not fall off the belt-like mount 24 during the transport of the label continuous body 42.
[0030]
The label piece 36 peeled off by the peeling plate 48 is drawn out below the suction board 50, sucked and held by the suction board 50, and the label piece 36 is attached to an object to be pasted 58, for example, cardboard, which has been conveyed by the conveyor 57 or the like. Affixed.
