Description

  The present invention relates to a fine pattern punching method and apparatus for punching a desired fine pattern on a roll-based substrate based on paper.

Conventionally, as a method of continuously punching a desired pattern on a paper-based roll-shaped substrate, the substrate is sandwiched between a roll such as a rubber roll and a die-cut roll having a metal blade corresponding to the desired pattern and inserted. The method of punching and letting go is often used.
However, in such a method, there is a drawback in that continuous punching is hindered because the material scrap generated when punching the material into a desired pattern is scattered in the vicinity of the roll. Since the metal blades used in the process are usually machine tools, it is difficult to manufacture metal blades corresponding to more than a certain amount of complex patterns. There was a drawback that it was not possible.

There is also a method of punching by laser cutting in a sheet or roll using a laser processing machine, but the minimum size of the handle that can be processed is small, but it is suitable for punching fine patterns, but it is a paper-based substrate However, there are problems such as burning of paper, mixing of burnt residue, and odor due to scorching, which leads to a production environment unsuitable for primary containers.
In addition, since laser cutting has a low processing speed, the production speed is slower than punching with a die cut roll, and there is a drawback that it cannot be applied to mass production.

For example, as a method using a normal punching machine for a single wafer, there is a normal punching method using a punching machine and an etching blade.
Although this method requires less processing cost, it has a problem that not only the minimum size of the punched pattern that can be processed is large, but also the removal of the scraps with a diameter of about 10 mm or more cannot be prevented.
In addition, there is a method using a punching mechanism with a waste storage box added to a normal punching mechanism using a sculpture blade on a single sheet, but this also completely prevents spilling out, and even closer patterns It is difficult to pull out and is not suitable for expressing fine patterns.

Moreover, as a punching method used for a plastic film, there is a method of punching a roll-shaped base material using a metal blade or a hot fusing blade.
For example, Patent Document 1 describes a method for punching and manufacturing a strip-shaped material that can be processed without scattering the scraps generated when a heat-cuttable material is punched into a desired pattern. Between the outer side of the thermal cutting roll having the shape of the cutting blade and the outer side of the backup roll, the hot-cutting strip-shaped material and the strip-shaped material and an adhesive receiving member having a sticking shape are overlapped and inserted. Thus, there has been proposed a method in which a desired pattern is punched in a strip-shaped material, and the scrap generated at this time is adhered to the scrap receiving member by welding, adhesion or the like and processed together with the receiving member for scraping the scrap.
According to this method, it is said that it is possible to provide a pattern punching manufacturing method for a strip-shaped material that can be processed without scattering the shavings generated when a heat-cuttable material is punched into a desired pattern.

However, when the method proposed in Patent Document 1 is used for a paper-based base material, problems such as paper burning caused by the heat of a hot fusing roll, mixing of burnt residue, and odor due to scorching are not torn. .
In addition, it is very difficult to confirm that a pattern having a shape corresponding to a desired punching pattern is adhered and separated and removed at a predetermined position of the receiving member.

  From the above situation, it can be processed without scattering the scraps generated when punching a paper-based substrate into a desired pattern, and it is easy to be surely punched into a desired pattern A new method for punching a fine pattern on a roll-shaped substrate that can be confirmed has been desired.

By suppressing the dimensional change due to the fluctuation of the tension, it is possible to more stably confirm that the dropout (6) is attached at a predetermined position using the image inspection machine (24).

The dropping receiving member (9) provides adhesion by forming a pressure-sensitive adhesive layer or an adhesive layer on the surface of the member base material that overlaps the roll-shaped base material.
As the base substrate, polyethylene terephthalate (PET), stretched polypropylene (OPP), polyvinyl chloride, cellophane, acetate, paper, cloth, or the like can be used.
As the pressure-sensitive adhesive or adhesive, acrylic adhesive, rubber or the like can be used.

In many cases, the roll-shaped substrate (2) is a paper such as a coated paper or a laminate of the paper and a resin film layer or a metal layer, but is not limited thereto. The thickness of the substrate is 200 μm or less, and preferably in the range of 50 μm to 130 μm.
In order to reduce damage to the punching blade, it is desirable to use a protective film on the surface opposite to the surface of the receiving member (9) to be superposed on the roll-shaped substrate.
As the protective film (12), polyethylene terephthalate (PET), stretched polypropylene (OPP), polyvinyl chloride, cellophane, acetate, paper, cloth and the like can be used.

The die-cut roll (10) is formed in a cylindrical shape whose surface is made of a magnesium alloy or the like that is usually suitable for etching, and the peripheral surface of the cylinder has a protruding shape corresponding to a desired punching pattern by chemical treatment such as etching. A punching blade (4) (see FIGS. 2 and 4) is provided.
The backup roll (11) has an outer peripheral surface formed of a soft material such as silicon rubber, and a roll-shaped base (2) inserted between the die-cut roll (10) and a receiving member (9) to be removed. Is pressed to the die-cut roll (10) side with a predetermined pressure, and the roll-shaped substrate (2) can be smoothly punched by the punching blade (4).
A cutting mechanism (not shown) having a cutting blade or the like may be provided between the punching step and the winding.
The roll-shaped base material (2) punched with a predetermined pattern by this cutting mechanism can be cut to an appropriate length.

  As described above, according to the fine punching method for the roll-shaped substrate of the present invention, the scraping member (6) is stuck to the adhesive of the scraping receiving member (9) and the scraping receiving member (9). , (12) is wound on the winder, so that the scraps (6) are not scattered below the die-cut roll (10), etc. Failures can be prevented.

  Further, since the scrap (6) is carried by being adhered or adhered to the scrap receiving member (9) as described above, the distribution of the scrap (6) by the image inspection machine from the surface of the scrap receiving member (9). By confirming the above, when the punching by the die cut roll (10) is incomplete, it can be reliably determined.

Further, the punching blade (4) provided in the die cut roll (10) is formed on the outer peripheral surface of the die cut roll (10) by a chemical treatment such as etching from a metal such as a magnesium alloy. Compared with the shape of the blade by processing, it becomes possible to manufacture a punching blade having a much more complicated shape, and it becomes possible to punch a complicated shape.
Further, since the punching blade (4) is formed by etching, the manufacturing cost is low, and therefore the die cut roll (10) can be provided at low cost.

In this embodiment, the die-cut roll (10) is made of a magnesium alloy, but the invention is not limited to this, and the die-cut roll (10) may be made of a metal that can be etched and has strength as a punching blade.
When the punching pattern is not complicated, the punching blade (4) of the die-cut roll (10) is not formed by etching, and a metal piece corresponding to machining or a desired pattern is fixed to the peripheral surface of a roll made of iron or the like. Although it may be formed, if it is formed by etching, there is an advantage that it is inexpensive.

Further, the outer peripheral surface of the backup roll (11) is not limited to a soft material such as silicon rubber, but may be formed of a hard member having excellent heat resistance. However, if the soft material is used, the punching blade (4) is damaged. There is an advantage that there is nothing.
Further, the supply of the roll-shaped base material (2) is not limited to the method of unwinding from the printed winding, but can also be supplied from a printing process by a printer directly connected in synchronization.
In this way, not only a simple punching pattern is formed on the roll-shaped substrate (2), but if a printing machine and a punching pattern are used in combination, there is an advantage that more various patterns can be formed in synchronization.
