Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for taking out a product that has been cut into a blade mold when a resin molded product or a mold material in which an assembled paper box is developed is pressed and cut.

[0002]

2. Description of the Related Art In a conventional cutting machine, for example, in a resin molded product, a blade mold having a Thomson blade is placed and fixed on a base plate, and a molded product in which a plurality of products are connected is arranged in the blade mold by a pressing action. It is cut into individual products with a blade.

At the time of this cutting, since the periphery of the product is press-cut by the Thomson blade, the cut product is bitten by the endlessly surrounded Thomson blade and bites into it, so that it touches the surrounding Thomson blade. It is necessary to grab and take out the product so as not to get hurt.

Therefore, an elastic body is installed at an appropriate place in the Thomson blade, and after pressing and cutting, the product in the Thomson blade is lifted by the restoring force of the elastic body and protruded from the upper surface of the Thomson blade to make the product safe. There are those which are taken out from the machine, or those which push up the product from the Thomson blade with a computer-controlled pushing device.

[0005]

When the above elastic body (actually, sponge) is used, it is necessary to adjust the shape and thickness of the sponge according to the blade type Thomson blade. Is required, and the amount of elastic body is considerable, so it is not effective in dealing with a wide variety of products in small lots. Further, the computer-controlled push-up device has no problem in working efficiency, but is expensive, and it is difficult to install it on the cutting machine currently in use, resulting in high equipment investment.

Therefore, the present invention is intended to provide a product take-out mechanism which can be used in a current cutting machine, can be mounted at low cost, and can ensure work safety.

[0007]

According to the present invention, a large number of through holes are arranged in a base plate for mounting and fixing a blade die having a Thomson blade arranged thereon, and a pin support is installed directly below the base plate so that it can be moved up and down. In order to push the pin that pushes up the product that bites into the blade type Thomson blade from the blade type into and out of the through hole on the base plate, the pin is selectively inserted into the through hole and supported by the pin support. is there.

Since the base plate is exposed in the blade type Thomson blade mounted and fixed on the base plate, a pin is formed in the through hole at an appropriate position of the exposed base plate in the Thomson blade according to the form of the product. By inserting, it is possible to stand upright by supporting it with a pin support installed directly below the base plate. Then, the product left after biting into the Thomson blade after press cutting rises as the pin support rises, so it is pushed up by the pin and pushed upward from the inside of the Thomson blade to separate, so it was separated. The product can be taken out safely and easily.

It suffices to insert the pin into the through hole of the base plate at a position which is considered necessary for pushing up depending on the shape of the product, and if the through hole is arbitrarily selected according to the shape of the product and the pin is inserted, It can be applied to products in any form.

If it cannot be handled by pushing up with a pin, if a flat auxiliary body is placed on the base plate in the Thomson blade and is interposed between the flat piece and the product, the flat auxiliary body supports the product. By pushing it up, the product can be reliably separated upward from the inside of the Thomson blade.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of an essential part showing a mechanism of the present invention. A base plate 2 is installed on a machine base 1, and a blade die 3 is placed and fixed on the base plate 2. Further, a pin support 4 is installed between the machine base 1 and the machine base 1 directly below the base plate 2 so as to be able to move up and down between the machine base 1 and the base plate 2 by a cylinder 5.

The base plate 2 is on the machine base 1 while maintaining a space 7 between the base plate 2 and the machine base 1 by stays 6, 6, ..., And through holes 8, 8, 8, ...
A large number of holes are provided at positions where the stays 6 and 6 do not exist at m intervals (in the vertical and horizontal directions), and at least about 10 in the space surrounded by the Thomson blades 10 of the blade type 3 to be mounted by the positioning block 9. Should appear.

The blade die 3 has a Thomson blade 10,
It is widely used in the past for arranging a plurality of 10 ... Endlessly, for example, a resin product obtained by continuously molding a plurality of products, and for cutting a folding box from a paperboard material into an expanded form.

The support 4 includes a frame 11 and a support plate 12,
The base plate 2 is attached to the frame body 11 which is composed of 12 ...
Between the stays 6 and 6, and corresponding to the positions where the through holes 8, 8, 8 ... Are provided, supporting plates 12, 12 ... Are provided, and the cylinder rod is provided on one of the facing surfaces of the frame body 11. 13 are connected and supported by a cylinder 5 erected on the machine base 1, and the support member 4 is supported by the expansion and contraction of the cylinder rod 13.
Moves up and down between the machine base 1 and the base plate 2.

Then, an optional through hole 8 in the base plate 2
When the pin 15 is inserted therein, the pin 15 is erected by being supported by the support plate 12 of the support body 4, and when the support body 4 rises, the pin 15 also rises and projects from the inserted through hole 8. . The length of the pin 15 is preferably such that the tip thereof is near the surface of the base plate 2 when the support body 4 is supported by the support rod 12 at the lowest descent point, and then the thickness of the support plate 12 and the base plate 2 (the through hole 8). (Inner circumference), and is accurately supported by the through hole 8 as a guide.

Therefore, by pushing up several positions from the through holes 8, 8 ... Appearing in each Thomson blade 10 of the blade die 3 in relation to the form of the product 16, the Thomson is exposed. By selecting the through holes 8, 8 ... Which are pushed up from the inside of the blade 10 and inserting the pins 15, 15, ... By operating the cylinder 5 and moving the support 4 up and down, it is easy and safe. The product 16 can be taken out of the Thomson blade 10 of the blade die 3.

FIG. 3 is a cross-sectional view showing an embodiment of claim 2, and the Thomson blade 10 is used when pushing up cannot be stably performed due to the relationship between the shape of the product 16 and the through hole 8. By placing a plate having an appropriate size or a flat auxiliary member 14 having a strength not to be deformed on the inner base plate 2 and interposing it between the product 16 and the pins 15, 15 ,. The product 16 above is supposed to be pushed up.

In this way, the pin 15 is raised and the product 1
By pushing up 6, the product is removed from the inside of the Thomson blade 10 and the product 16 is placed above the Thomson blade 10.
Since the product floats, the product 16 can be taken out safely and easily without contacting the Thomson blade 10.

When the cylinder rod 13 is lowered after the product 16 is taken out, the pins 15, 15 ... Also descend as the support plate 12 descends, and the head of the pins 15 is depressed below the upper surface of the base plate 2. In preparation for the next press cutting and pushing up of the product 16.

[0020]

As described above, according to the present invention, by appropriately selecting the through hole appearing in the Thomson blade formed in the blade mold according to the product and inserting the pin, Thomson after press cutting. The product bites into the blade can be pushed up to be taken out safely and easily.Because you can select the through hole to insert the pin according to the product, it has versatility for the product even with a simple structure It can be attached to a cutting machine, and has the effect that it can be provided at a significantly lower cost than a computer-controlled one.
