Abstract

PURPOSE:To keep uniformity of punched products as well as to improve efficiency by advancing an underlay mat forward as crossed with a packaging material, and shifting the position of punched marks on the underlay mat. CONSTITUTION:A material sheet is perforated by a Thomson trimming die 2 and intermittently or continuously moved, thus cut operation is repeatedly carried out. At this time, a crossing mat 3 laid down as crossed with the underside of the material sheet 1 at a lower part of the trimming die is moved in succession and it comes to such a position as different in punched marks 31 at all times. In this connection, as for a suchlike one as not fully opened like half-cut and perforation and moved together with the material sheet 1, it is desirable that the crossing mat 3 uses a nonadhesive woven fabric, nonwoven fabric, film or the like as materials in order to facilitate its separation from the material sheet 1 after the cut process.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of Application The present invention is capable of cutting pharmaceuticals by half-cutting, dot-cutting, or completely punch-cutting packaging materials such as paper, plastic films, and aluminum foil laminated sheets. This invention relates to a method for punching and cutting packaging materials used for lids and other containers for foods, cosmetics, etc.

(b), Conventional Technology Conventionally, when punching resin film, paper, aluminum foil processed sheets, etc. for the above purpose, it is performed by applying pressure with a Thomson blade or the like from a sheet or tape-shaped material. However, normally only the material moves sequentially and the underlying base mat is fixed, so if the cutting edge is repeatedly pressurized, the surface of the pace mat may be damaged or worn, resulting in loss of uniformity and adversely affecting the product. Not only did this cause a problem, but the wear and tear on the cutting edge was also large.

Furthermore, there were many drawbacks, such as the need for a removal mechanism such as a male and female blade in order to continuously take out the punched products, to continuously manufacture the punched products as products, and to collect the punched dregs at the same time. .

(e) Problems to be Solved by the Invention In view of the many drawbacks of the prior art as described above, the present invention aims to prevent the fi 41 of Besmat from being worn out due to repeated pressure using a Thomson blade, etc. Dotting improves the efficiency of cutting operations and reduces wear and tear on the cutting edge. In addition, even when cutting completely, the punched product is collected on a mat, and the hole punching allows the product to be manufactured continuously. This work was completed with the aim of providing a processing method that can improve manufacturing efficiency and reduce costs.

(d) Means for Solving Problem 1 The present invention will be specifically explained below based on drawings showing examples of implementation.

Packaging materials (1) For example, when making continuous cuts on processed aluminum foil, sheets of paper, plastic films, tapes, etc., with a Thomson blade (2), etc., the underlay mat is crossed with the packaging material 11) (usually at right angles, but This is characterized in that the position (31) of the punching mark on the underlay 77) (3) (hereinafter referred to as the crossing mat) is moved every time the punching process is performed.

For example, Fig. 1 is a plan view of an example of dotted cutting of an aluminum foil processing sheet, but the material sheet (1) is dotted and cut by a Thomson cutting die (2) intermittently or continuously. The cutting process is repeated and the cutting process is repeated, but the crossing mat (3) laid across the lower surface of the cutting die (1) is moved one after another and the cutting marks (31) are always at different positions. Do as you like.

In addition, for half cuts and dotted cuts that do not open completely and move together with the material sheet +1), the crossing mat (3) is used as a material to facilitate separation from the material sheet +11 after the cutting process. It is preferable to use non-adhesive woven fabric, non-woven fabric, film, etc. (hereinafter referred to as separate cloth, separate film, etc.).

FIG. 2 is a plan view showing an example of carrying out a complete cut.
In order to obtain a fully punched punched product (13) or a punched product (32), the process must naturally be carried out depending on the size of the cutting die.

Furthermore, in this case, in order to collect the die-cut product (32) or scraps on the crossing mat (3) without leaving them in the mold, the material of the cutting mat (3) is adhesive paper,
Preferably, it is an adhesive film or the like.

FIG. 3 is a plan view showing a mass-produced cosmetic container lid made of an aluminum foil processed sheet according to the present invention. In other words, in addition to performing multiple dots (11) at the same time, holes (13) for fixing the position when covering the container are provided in the four corners of the container by cutting, thereby contributing to improving the efficiency of automatic production.

In the above case, the cutting process for marking (11) and the cutting process for drilling holes (13) can be done in separate processes, but they can be done in the same process depending on the material of the crossing mat, etc. You can also do that.

(e) 8 Effects The punch-cutting method for packaging materials according to the present invention prevents damage, wear, etc. to the pacemat and maintains the longevity of the cutting edge by sequentially moving the underlying crossing cloth at the same time as the punching process. Furthermore, by making the crossing cloth separable, adhesive, etc. depending on the purpose, the mechanism can be simplified and production efficiency can be improved.

(f) 1 Effect of the invention This invention provides 1 of the pace mat (crossing cloth).
1. By eliminating scratches, deformation, etc., it maintains the uniformity of punched products and improves efficiency. It also prevents deformation, wear, etc. of the cutting edge, lowering production costs, and furthermore, it is possible to dispose of all punched products and scraps. This is a new cutting method that can omit conventional complicated mechanisms and processes.

Claims (3)

[Claims] (1) When making continuous punch-cuts on roll-shaped or flat-shaped long packaging materials using a Thomson blade, etc., the underlay mat should also be advanced so as to intersect with the packaging material to move the position of the punch marks on the underlay mat. Features a punch-cutting method for packaging materials. (2) The punch-cutting method according to claim (1), wherein the mat is moved so that the position of the punching die on the mat always changes during the half-cut or dotted cut. (3) The punch-cutting method according to claim (1), wherein the mat is moved in accordance with the size of the punching die during the complete punch-cutting.
