A second work support device 27 in the form of an endless conveyor is provided horizontally through the column 5, and its end near the die 25 is held in a horizontal state by a fluid pressure device 29 (see FIGS. 1 and 3). It can be freely swung downwards from the top.

In front of the lower frame 3 mentioned above (to the left in Figs. 1 and 2), there is a table bed 3 of the same level height.
1 is provided, and side tables 35, 35 are mounted on parallel Y-axis horizontal guide rails 33, 33 provided between the table bed 31 and the lower frame 3, and are movable in the front and back direction of the punch press 1. It is provided.

The above-mentioned side tables 35, 35 are integrated with a carriage base 37 that spans the front end side (the left end side in FIGS. 1 and 2), and the carriage base 37 is rotated by a Y-axis motor 39. It is connected to a nut member (not shown) that is screwed into the driven Y-axis feed screw 41.

An X-axis feed screw 45 driven by an X-axis motor 43 is provided on the carriage base 37, and a nut member 47 is screwed into the X-axis feed screw 45.
The carriage 5 is guided by an X-axis horizontal guide 49 provided on the punch press 1 side of the carriage base 37 and is movable in the X-axis direction (vertical direction in FIG. 2).
1 is provided.

On the punch press 1 side of the carriage 51,
A plurality of gripping claw devices 53, 53 are provided and can grip and release one end side of the workpiece W.

On the table bed 31 described above, a first work support device 55 is provided on the side opposite to the processing position of the punch press 1, with the height and width center in the horizontal state aligned with the second work support device 27 described above. .

This first workpiece support device 55 may be of a caterpillar type, for example, which extends around sprockets 57, 57, and can be attached to the carriage base 3 by appropriate means.
7, it is configured to move toward and away from the processing position in synchronization with the processing position.

The above-described first work support device 55, side tables 35, 35, and second work support table 2
A large number of rolling wheels 59 that are rotatable in the left and right directions (up and down in FIG. 2) are buried in the upper surface of the workpiece 7. It is made so that it does not cause any damage.

Further, the second workpiece support device 27 described above is configured to be able to move toward and away from the processing position of the first workpiece support device 55 in synchronization with an appropriate means (not shown) in the same direction. It is.

Since the first and second work support devices 55 and 27 are driven separately, a configuration in which both are synchronized is, for example, rotating the motor for driving the second work support device 27 with the rotation of the motor that drives the first work support device 27. This can be easily implemented by appropriate means such as synchronizing with the movement of 55.

The apparatus of this embodiment described in detail above is provided with a first work supporting device that moves in synchronization with the movement of the workpiece at a position where the workpiece approaches and leaves the processing position of the punch press from one side, and Since a second workpiece support is provided on the other side to transport the product to the rear of the punch press, the flow direction of the punching process is unidirectional, resulting in highly efficient assembly work.

Furthermore, since the second work support device for transporting the processed product to the rear of the punch press is provided so as to be able to move in synchronization with the movement speed of the first work support device, there is a gap between the product and the second work support device in the process of transporting the product. This eliminates the inconvenience of scratching the product.

Furthermore, since a large number of wheels that can freely roll in a direction perpendicular to the direction of workpiece conveyance are provided on the upper surfaces of the first workpiece support device and the second workpiece support device, the point contact of the conventional ball bushing becomes a line contact, and the carriage This solves the conventional problem of creating groove-like dents on the workpiece even when the workpiece is moved in the orthogonal direction.

In addition, since the processing position end of the second workpiece support device is configured to be able to freely swing downward from the horizontal state, the product cut from the material does not interfere with the material, as shown in Figure 3. This also had the effect of allowing it to be transported to the rear of the vehicle.
