Description

DETAILED DESCRIPTION OF THE INVENTION (a). INDUSTRIAL APPLICABILITY The present invention relates to packaging materials such as paper, plastic film,
By performing half-cutting, dot-cutting, and full-cutting of aluminum foil laminated sheets, etc.,
The present invention relates to a method for punching and cutting packaging materials used for cheerful lids and the like of cosmetics and the like.

(B). Conventional technology Conventionally, for the above-described purpose, when punching a resin film, paper, aluminum foil processed sheet, etc., it is performed by pressing a Thomson blade or the like from a sheet or tape material, but usually, Only the material moves sequentially, and the underlying base mat is in a fixed state, so if the cutting edge is repeatedly pressed, the surface of the base mat loses uniformity as damage or abrasion, not only adversely affecting the product, The wear of the cutting edge was also great.

Further, there are many drawbacks, such as the necessity of taking out mechanisms such as male and female blades in order to continuously take out punched products or to continuously manufacture perforated products as products while simultaneously collecting chips.

(C). Problems to be Solved by the Invention In view of the above-mentioned many disadvantages of the prior art, the present invention prevents damage and wear of a base mat due to repeated pressurization of a Thomson blade or the like, and performs half cut, spotted cut, etc. In order to improve the efficiency of the cutting work and reduce the wear of the cutting edge, and also in the case of full-cut cutting, manufacturing by collecting cut products or chips on the mat and continuously manufacturing perforated products The purpose of the present invention is to provide a processing method capable of improving efficiency and reducing costs.

(D). Means for Solving the Problems The present invention will be specifically described below with reference to the drawings showing the embodiments.

Packaging materials (1) For example, sheets of aluminum foil, paper, plastic films, etc., tapes, etc., Thomson blades (2)
When the continuous mat is performed, the underlay mat (3) (hereinafter, referred to as a crossing mat) is moved by crossing the underlay mat with the packaging material (1) (usually at a right angle but at another angle). The upper cut product or chip is moved from the cut position together with the position of the cut mark (31).

For example, FIG. 1 is a plan view of an embodiment of a dot cutting of an aluminum foil processed sheet. A material sheet (1) is cut with a dot by a Thomson punching die (2) and moves intermittently or continuously. Although the cutting process is repeatedly performed, the crossing mat (3) laid across the lower surface of the punching lower material sheet (1) moves sequentially and always moves along the punching mark (3).
So that 1) is at a different position.

The crossing mat (3) that moves together with the material sheet (1) without completely opening it, such as a half cut and a dot cut, is used to facilitate separation from the material sheet (1) after the cutting process. Non-tacky woven fabric, as material to
It is preferable to use a nonwoven fabric, a film, or the like (hereinafter, referred to as a separate cloth, a separate film, or the like).

FIG. 2 is a plan view showing an example of the implementation of the full-cutting. In this case, the width of the movement of the crossing mat (3) depends on the punched product (13) or the punched product (32). In order to obtain (3), it must be done according to the size of the punch.

Further, in this case, at least the surface of the crushing mat (3) on the material sheet side has adhesiveness to the material sheet. Specifically, for example, an adhesive paper or an adhesive film is used as a material of the crossing mat (3). If the surface of the crossing mat is adhesive, the material sheet portion pressed by the Thomson blade during cutting adheres to the surface of the crossing mat. Therefore, at the end of the cutting operation, the cut object (cut product or chip) is collected on the mat. On the other hand, the crossing mat (3) sequentially moves in a direction perpendicular to the direction of travel of the material sheet. Therefore, since the cutting object collected on the mat is moved from the cutting position, it is not cut at the cutting position a plurality of times, and the cut shape is not damaged. In addition, due to the movement of the crossing mat, the cutting object or the trace of the Thomson blade moves from the cutting position, and a new crossing mat surface is constantly updated at the cutting position. Therefore, cutting can always be performed under favorable conditions, and continuous production of high-quality cut processed products becomes possible.

FIG. 3 is a plan view showing a lid for a mass-produced cosmetic container made of a processed aluminum foil sheet according to the present invention. That is, a large number of spotting cuts (11) are performed simultaneously, and holes for fixing the position at the time of lid cover are provided in the four corners and the like by cutting, thereby contributing to an improvement in the efficiency of automatic production.

In the above case, the spotting cut (11) and the perforated cut (13) can be performed separately from the cutting process.
It can also be performed in the same process by considering the material of the crossing mat and the like.

(E). The cutting method of the packaging material according to the present invention is intended to prevent damage to the base mat, abrasion, etc., maintain the cutting edge lasting, and for the purpose by sequentially moving the underlying crossing cloth simultaneously with the punching process. Accordingly, by making the crossing cloth separate or sticky, the mechanism can be simplified and the production efficiency can be improved.

(F). EFFECT OF THE INVENTION The present invention achieves the production cost by maintaining the uniformity of the punched product and improving the efficiency by eliminating damage and deformation of the base mat (crossing cloth), and preventing the deformation and wear of the cutting edge. To reduce. In particular, according to the present invention, it is possible to surely and smoothly collect a cut product or a chip without using a complicated mechanism or process. That is, according to the present invention, a remarkable effect that the improvement of the productivity and the improvement of the quality of the cut product can be simultaneously achieved while simplifying the mechanism is obtained.
