Description

Detailed Description of the Invention The present invention provides a method for creating grooves and streaks at desired positions on cardboard or thin steel plates, such as the folds of packaging boxes. This invention relates to a mounting device for a grooved master mold that is mounted on a cutting plate.

Generally, creases, etc. in packaging boxes are created by interposing paper or the like between a pressed line and a groove provided opposite to it, and by a press operation. Often used is a method in which a sheet of carbon paper or the like is laid down on a plate, a pressed line is pressed, and a matrix is attached with grooves formed along the pressed line marks on the surface of the cutting plate.

However, this method requires a lot of effort to attach the matrix, and there are many concerns about accuracy, and there are also drawbacks such as a time loss in the attachment work. Therefore, the present applicant has invented a method in which a magnet is first magnetically attached to the side surface of the stamping rule, a magnetically grooved matrix is attached to the magnet, and the matrix is adhered to the cutting surface using a press operation. , which has been filed as Japanese Patent Application No. 1978-7823y.
Even in such a system, various drawbacks occur. In other words, if the protrusion of the press line from the main cutting die is small or the magnetic attraction force of the magnet is weak, it cannot be guaranteed that the magnet will be reliably attached to the press line, and the magnet may be damaged due to some impact during press operation. There is a high risk that the magnet will fall off, and this falling off will not only cause a situation where the master mold cannot be attached to the cutting surface accurately, but also that it will stop immediately if the magnet falls off after the master mold is attached. There is also a risk that the magnet will be pressed by the press line as the main cutting die moves up and down, and the press line may be damaged. In view of the above, the present invention aims to provide a new and improved mother die mounting device, which includes a magnetically adhesive press line 1,
A retaining body 3 is provided on the bottom surface of the main cutting die 2 along the stamping line 1, a magnet 4 is magnetically attached to the magnetic body 3 on the top surface and the stamping line 1 on the side surface, and a groove 7 is formed in the longitudinal direction of the top surface. It is characterized by comprising a matrix 6 which is provided with an adhesive 9 on its lower surface and is magnetically attached to the lower surface of the magnet 4 with the stamping lines 1 facing the grooves 7.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a magnetically-adhesive pressing rule, which is protruded from a suitable position on the lower surface of a book-cutting die 2 that moves up and down. 3 is a retaining body provided by gluing or embedding on the bottom surface of the main cutting die 2 along the stamping line 1, and there is a lotus setting.
are separated.

Reference numeral 4 denotes a magnet whose upper surface is magnetically attached to the magnetic body 3 and its side surface is magnetically attached to the pressing rule 1. For example, a rubber magnet is used, and a guide 5 extending parallel to the pressing line 1 is formed protruding downwardly. Reference numeral 6 denotes the longest matrix having an appropriate groove 7 in the longitudinal direction at the center of the upper surface, and an adhesive 9 protected by a release paper 8 on the lower surface.
A magnetic material such as 0 is interposed or mixed therein, or the material is formed of a magnetic material itself and has magnetic property.

11 is a cutting plate to which the mother mold 6 is attached;
2 is cardboard to which folds are added.

Then, press ruled lines 1 at the necessary places to make creases with book cutting die 2.
Attach a magnet 4 to one side or both sides of this pressed line 1, the top surface of which is attached to the adhesive body 3, and the side surface of which is adhered to the pressed rule 1,
A matrix 6 having an appropriate groove 7 in the longitudinal direction at the center of the upper surface on the lower surface of the magnet 4 and an adhesive 9 provided on the lower surface is magnetically attached with the release paper 8 protecting the adhesive 9 removed.

The magnetic attachment of the magnet 4, the magnetic attachment of the master mold 6, and the peeling off of the release paper 8 can be performed not only before the main cutting die 2 is attached to a press operation machine, but also afterward. Next, the main die 2 is lowered by a press operation, and the master die 6 is pressed by the magnet 4 and adhered to the cutting plate 11.

As a result, the mother die 6 is attached to the cutting plate 11 with the groove 7 accurately aligned with the press line 1.
The work is completed by removing the magnet 4 after attaching the mother mold 6.
At this time, the magnet 4 is in a state of being adhered to the stamping rule 1 and the magnetized body 3, and can be easily removed. In this way, pressed line 1
At the same time, the matrix 6 is magnetically attached to the magnet 4 which is attached to both of the magnetized body 3, and the matrix 6 is attached to the cutting plate 1 by lowering the pressing line 1.
1, it is possible to install the groove 7 in the correct position relative to the t-pressing line 1, and it is possible to reliably create creases, etc. according to the purpose, and the use of the magnet 4 simplifies the work. It is possible to create a matrix 6 without requiring advanced technology.
Installation work can be done, time loss can be prevented, and
Since the magnet 4 is magnetically attached to both the ruled line 1 and the magnetically attached body 3 and is strongly attached, there is no chance of it falling off unexpectedly or causing any problems associated with it, and it can not only be used safely, but also It is also economically advantageous because the magnet 4 can be used repeatedly over a long period of time. In addition, when the magnet 4 is a rubber magnet, when adhering the matrix 6 to the cutting plate 11, the elasticity of the rubber magnet can be used to press it, and not only can the adhesion be made flexibly and strongly. Even if the magnet 4 were to fall off, accidental damage to the ruled line 1 can be prevented. Furthermore, magnet 4
By forming a protruding guide 5 parallel to the pressing rule 1 below, the guide 5 can be inserted into the groove 7 of the matrix 6 or
The matrix 6 can be pressed by contacting the outer edge of the press line 1.
The position of the groove 7 of the matrix 6 relative to the mold 6 can be made even more accurate, and folds etc. with extremely high precision can be reliably created.

As described above, the present invention aims at accuracy in attaching the master die 6 having the grooves 7 for creating folds etc. of the packaging box to the cutting plate 11, and also simplifies the work and uses advanced technology. It has various effects such as being able to carry out the necessary work without any delay, preventing time loss of work, and being economically advantageous.
