Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cutting device that cuts a strip plate to a predetermined width and continuously obtains narrow pieces.

Up until now, when cutting strips to a predetermined width to obtain small-width products, the strips were sent out with rolls and then cut, but due to roll slips, accurate feeding was not possible, and the strips were continuously cut to the same size. There is a problem in that it is not possible to obtain narrow width products.

The present invention solves these problems and provides an automatic cutting device with less material loss, and will be described in detail below with reference to the accompanying drawings.

In FIGS. 1A and 1B, reference numeral 1 denotes a towing body, and a chuck 2 is fixed to one end of the towing body 1 with screws, bolts, or the like. 3 is a fixed plate that moves up and down,
The fixing plate 3 cooperates with a cylinder 31 attached at the bottom as shown in FIG.
To move the cylinder 31 by a predetermined distance to the right, the fixed plate 3 is lowered and the towing body 1 is held between the fixed plate 3 and the tip of the cylinder 31, and in this state, the cylinder 31 is driven to the right by a predetermined distance. After driving, the fixed plate 3 is raised to release the clamping state, and the fixed plate 3 and the cylinder 31 are driven to return to their original state.
By repeating this process, the pulling body 1 is intermittently moved in one direction by the movement width of the fixed plate 3.

4 is a conveyance belt which is held by the chuck 2 and moves a predetermined distance in synchronization with the intermittent movement of the towing body 1;
A belt-shaped plate A is temporarily fixed onto the conveyor belt 4 with an adhesive tape B.

Reference numeral 5 denotes a vertically moving cutting mechanism provided above the conveyor belt 4, and the mechanism 5 includes a cutting blade 52 and a blade fixture 51.
The width of the vertical movement of the mechanism is appropriately controlled, and is set so that the belt-shaped plate A is cut but the conveyor 4 is not cut. The cutting mechanism set in this manner is driven to cut the strip plate that is fed out as the conveyance strip moves as described above.

In the cutting device of the present invention, as described above, the strip plate A is fixed to the conveyor belt and is fed out by the moving width of the pulling body, so the feeding length accuracy is high and narrow-width objects of the same size can be continuously cut. It has the characteristic that it can be obtained from

Furthermore, there is the advantage that material loss can be eliminated by setting the tip of the strip plate below the blade when cutting is started.
