Abstract

<P>PROBLEM TO BE SOLVED: To enable continuous half cutting in the direction of the transfer of label paper at limited costs. <P>SOLUTION: A flexible die 1 is provided, at least, with a pushing-out edge for forming a half cut ranging between the top and bottom of each label. With a magnet cylinder 2 being rotated at a constant speed, the label paper S is transferred so that there is a distance enabling the terminating end of the preceding half cut and the leading end of the following half cut to be separated and also so that each transfer speed when the starting point of the pushing-out edge commences to touch the label paper S and when the terminating point of the pushing-out edge leaves the label paper S is the same as the peripheral speed of the magnet cylinder 2. It is feasible to easily perform continuous half cutting in the direction of the transfer of the label paper, despite the flexible die which is intrinsically incapable of endless processing. Continuous half cuts can be formed at limited costs with the use of the inexpensive flexible die and without using an expensive die cutting roll. <P>COPYRIGHT: (C)2004,JPO

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label processing machine used to form a continuous label product by performing a half-cut process on a rolled label sheet that has been printed or partially processed.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when manufacturing a label product in a continuous state, a label device has been used as a device for performing a half cut corresponding to each of many types and finishing the product. As this label processing machine, a machine using a die cut roll in which a punching blade is formed directly on a cylinder is used. Further, there is also used one using a press-off roll formed by winding a flexible die having a press-cutting blade formed on a sheet-like metal plate around a magnet cylinder.
[0003]
[Problems to be solved by the invention]
The die-cut roll described in the former among those described in the prior art is a roll in which a punching blade is formed on the surface of the cylinder by engraving, and it is engraved exclusively, so it is expensive and used during polishing. However, there is a problem that a spare roll is required. On the other hand, the flexible die described in the latter is a thin plate-shaped corrosion blade type formed by etching, and the blade type is disposable and has the advantage that various types can be replaced. When wound around, there is a problem that a cut portion of the blade die is formed in a part of the outer periphery, so that it is not possible to perform endless processing.
[0004]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a label processing machine that enables continuous half-cut in a label paper transport direction while suppressing costs. To provide.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the label processing machine of the present invention uses a pressing roll formed by winding a flexible die having a patterned pressing blade formed on a sheet-shaped metal plate around a magnet cylinder, and a receiving roll. In a label processing machine that forms a continuous label product by performing half-cut processing with a pressing blade while conveying the label paper therebetween, a flexible die is a pressing blade for forming a half cut extending between the top and bottom of each label. With respect to the magnet cylinder rotating at a constant speed, the end point of the previous half-cut and the start end of the next half-cut have a distance that can be separated, and the starting point of the pressing blade is The transfer speed when starting to hit the label paper and when the end point moves away from the label paper are respectively set by the magnet cylinder. It is characterized by comprising an intermittent transfer mechanism for transferring the label sheet so as to be fast with the same speed.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
[0007]
FIG. 1 is an external perspective view showing an example of a label processing machine according to the present invention. As shown in the drawing, a pressing roll 3 formed by winding a sheet-shaped flexible die 1 around a magnet cylinder 2 and a receiving roll 4 opposed thereto are shown. Are supported in a parallel state by bearings (not shown), and the label paper S is conveyed between them. The label paper S is transported by hooking marginal punches provided on both sides, that is, transport pin holes 5 on a pin tractor of a paper transport mechanism.
[0008]
The flexible die 1 is obtained by sharpening a pattern-shaped cutting blade by etching a sheet-shaped metal thin plate, and the magnet cylinder 2 is formed by winding and fixing the sheet-shaped flexible die 1. The displacement of the flexible die 1 is prevented by the magnetic force.
[0009]
The label paper S conveyed between the push-off roll 3 and the receiving roll 4 is a continuous paper-like label material that has been printed or partially processed. Then, by passing the label paper S through a label processing machine, an island-like processing and a processing of peeling off at both ends are performed to form a label product. As described above, the basic structure is the same as that of a commercially available product, but the label processing machine of the present invention is different in the operation of transporting the label paper S.
[0010]
FIG. 2 shows an example of a half-cut label sheet. The label paper S shown in the drawing is a continuous paper in which a backing sheet coated with an adhesive and a release paper coated with the adhesive in a releasable manner are laminated, and in the longitudinal direction according to the use of the final product. The horizontal perforations 6 are formed at predetermined intervals, and by separating from the horizontal perforations 6, labels can be divided for each unit. Further, in the marginal areas 7 on both sides of the label paper S, pin holes 5 for hooking and transporting by a pin tractor of the transport mechanism are formed at predetermined intervals.
[0011]
Then, the marginal area 7 is scraped off from the release paper in a state where the mount and the adhesive are connected in the longitudinal direction as unnecessary parts. Specifically, after making a continuous half cut a at the boundary of the marginal area 7 of the mount, the mount and the adhesive in the marginal area 7 are rolled up as unnecessary parts and removed.
[0012]
A procedure for forming such a continuous half cut by the label processing machine of the present invention will be described in order with reference to FIGS. In FIGS. 3 to 8, reference numeral 1 a denotes a part of the pressing blade of the flexible die 1 wound around the magnet cylinder 2. That is, the cutting blade 1a for forming a half cut extending between the top and bottom of each label, and the label processing machine of the present invention continuously cuts the label sheet S by the cutting blade 1a which is not continuous in the wound state. The half cut is performed.
[0013]
First, in FIG. 3, the label paper S is conveyed forward at the same speed as the peripheral speed of the magnet cylinder 2, and the pressing blade 1 a protruding outside the magnet cylinder 2 makes a half cut on the label paper S. That is, half cuts from the X point to the Y point, which is the top and bottom of one label on the label sheet S, are to be formed, corresponding to the start point A to the end point B of the press cutting blade 1a.
[0014]
Then, as shown in FIG. 4, the feeding of the label paper S starts to be stopped at the position of the axis O at which the end point B of the pressing blade 1a reaches the Y point of the sheet S, and the position of the axis O as shown in FIG. The feeding of the label paper S is completely stopped at a point when the label paper S has gone a little over. In this way, by setting the conveying speed when the end point B of the push cutting blade 1a separates from the label paper S to be the same as the peripheral speed of the magnet cylinder 2, and stopping the feeding of the label paper S slightly shortly therefrom, the half-cut processing can be performed. Make it smooth.
[0015]
Next, as shown in FIG. 6, when the pressing blade 1a is not in contact with the label paper S, the label paper S is transported in the reverse direction. Then, as shown in FIG. 7, the label sheet S is returned until the point Y has moved a little over the position of the axis O, and then the label sheet S is started to be conveyed in the forward direction. The label sheet is conveyed so that the starting point A of the pressing blade 1a coincides with the Y point of the sheet S and has the same speed as the label sheet S. In this manner, the label paper S is started to be conveyed from a little behind where it comes into contact with the starting point of the pushing blade 1a, and the conveying speed when the starting point of the pushing blade 1a starts to hit the label paper S is made equal to the peripheral speed of the magnet cylinder 2. Makes the half-cut processing smooth.
[0016]
Then, the label paper S is half-cut by the pressing blade 1a as it is, and the state returns to the state of FIG. By intermittently transporting the label sheet S in this way, the cut by the start point A and the end point B of the pushing and cutting blade 1a is smoothly connected, and continuous half-cut processing can be performed on the label sheet S.
[0017]
Normally, when continuous half-cutting is performed with the punching blade always in contact with the label paper, as in the case of a die cut roll, there is a problem that the label paper tends to meander. Then, once shifted, a phenomenon occurs in which the paper continues to meander. On the other hand, in the half-cut processing described above, since there exists a state in which the pressing blade 1a does not contact the label paper S, the deflection of the label paper S returns to the original state during that time, and the influence on the paper meandering is avoided. Can be. Therefore, the cut by the starting point A and the ending point B of the pushing and cutting blade 1a is not largely shifted, and the cutting is not connected to the extent that the breaking is not possible at the time of raising.
[0018]
In the description of FIGS. 3 to 8 described above, an ideal case in which the cuts at the start point A and the end point B of the push cutting blade 1a completely coincide with each other at the axis O of the magnet cylinder 2 has been described. However, it may be separated by a distance that can be separated at the time of raising. Substantially, the intermittent transport mechanism of the paper S may be any as long as it transports the paper S such that the end of the previous half cut and the start of the next half cut are within 0.3 mm.
[0019]
In addition, the cuts at the start point A and the end point B of the push-cutting blade 1a may overlap in the transport direction. In this way, when the cut-off blade 1a is overlapped before and after the half-cut, the length of the push-cutting blade 1a will What is necessary is just to make it about 1 to 3 mm longer than the size, shake it upside down, and make an overlap of about 0.5 to 1 mm respectively.
[0020]
As described above, the embodiment of the present invention has been described in detail with reference to one specific example. However, the label processing machine according to the present invention is not limited to the above-described embodiment at all, and the purpose of the present invention is described. Naturally, various changes can be made without departing from the scope.
[0021]
【The invention's effect】
The label processing machine of the present invention uses a press-off roll formed by winding a flexible die, in which a pattern-like press-cutting blade is formed on a sheet-like metal plate, around a magnet cylinder, and press-cuts the sheet while transporting the label paper between it and a receiving roll. In a label processing machine that forms a continuous label product by performing half-cut processing with a blade, the flexible die has at least a pressing blade for forming a half cut extending between the top and bottom of each label, and has a constant speed. With respect to the magnet cylinder rotating at the position, the end of the previous half-cut and the start of the next half-cut should be separated from each other, and the start and end points of the pressing blade start and end on the label paper. Label the paper so that the transport speed when leaving the paper is the same as the peripheral speed of the magnet cylinder. It features an intermittent transport mechanism for transporting paper, so it can easily perform continuous half-cuts in the label paper transport direction, despite being a flexible die that cannot be processed endlessly. Becomes possible. Therefore, a continuous half cut can be formed by using an inexpensive flexible die without using an expensive die cut roll while controlling the cost.
