When the drive motor 55 is driven, the drive pulley 57 is rotated, and this rotation is transmitted to the cylindrical grindstone 47 via the belt 61 and the driven pulley 59, and the cylindrical grindstone 47 is rotated at a desired rotational speed. Become.

Since a workpiece passing sensor 69 is provided at the end of the rear part of the transfer table 45, the workpiece processed by the turret punch press 1 is clamped by the clamp 41 of the unloading device 25 and the workpiece is loaded. When the work is carried out to the unloading device 3, it is possible to detect that the tip of the work has passed.

The side plate 21S of the main body frame 21
The entirety of the deburring device 43 provided on the side of the turret punch press 1 is surrounded by a cover 71. To the rear end of the cover 71, for example, one end of a connection pipe 73 as a connection member is connected, and to the other end of the connection pipe 73, a dust collector 75 is connected.

With the above configuration, when the dust collector 75 is operated, the burrs removed by the deburring device 43 are collected by the dust collector 75 via the connecting pipe 73.

After the work W is carried into the turret punch press 1 from the work loading / unloading device 3, punching is performed by the turret punch press 1, and the operation until the processed work W is carried out to the work loading / unloading device 3. Will be described.

First, as shown in FIG.
The work W is transferred from the work loading / unloading device 3 to the work table 1 of the turret punch press 1 by the loading device 23.
3 and the work W
Is punched.

The work W punched by the turret punch press 1 is, as shown in FIG.
After the clamp 41 of the unloading device 25 advances to the turret punch press 1 side to clamp the edge of the work W, it is retracted to the work loading / unloading device 3 and carried out.

When the work W is carried out to the work loading / unloading device 3 side, as shown in FIG.
Of the workpiece W is detected by the workpiece passing sensor 69.
Is confirmed to have passed. Thereafter, the drive motor 55
Is driven and the air cylinders 51F and 51B are operated, the cylindrical grindstone 47 rises while rotating and comes into contact with the lower surface of the work W. The air cylinder 51F,
By disposing a pressure reducing valve (regulator) in the pneumatic circuit of the upper cylinder chamber of 51 </ b> B, the contact force of the cylindrical grindstone 47 on the lower surface of the work W can be made constant.

As shown in FIG. 3B, when the work W clamped by the clamp 41 of the unloading device 25 is further retracted, the work W passes over the cylindrical grindstone 47 and the lower surface of the work W Burrs adhering to the surface are removed.

As shown in FIG. 3C, when the rear end of the work W passes the work passing sensor 69, the rotation of the cylindrical grindstone 47 is stopped and the cylindrical grindstone 47 is lowered to the original position. Is done. If the dust collector 75 is operated while the work W is passing over the cylindrical grindstone 47, the work W
The burr removed from the dust is collected by the dust collector 75 via the connection pipe 73.

As described above, by providing the deburring device 3 on the side of the turret punch press 1 of the main body frame 21 in the work loading / unloading device 3, the turret punch press 1
When the work W is carried out to the work loading / unloading device 3 from
Burrs on the lower surface of the work W can be automatically removed. Therefore, it is not necessary to perform a deburring operation in another step, and the work W can be transported as it is in the next step, so that the processing time can be reduced.

Since the cylindrical grindstone 47 of the deburring device 43 is moved up and down by the air cylinders 51F and 51B and rotated by the drive motor 55, the work W
The burr can be automatically removed while unloading the workpiece, and the deburring device 43 can be provided in the work loading / unloading device 3 after installation.

The deburring device 43 is surrounded by a cover 71, and a part of the cover 71 is connected to a dust collector 7 through a connecting pipe 73.
Since the burrs 5 are provided, the removed burrs can be collected by the dust collector 75 without scattering.

Since the work passing sensor 69 is provided on the turret punch press 1 side of the body frame 21 of the work loading / unloading device 3, when the work W is carried out from the turret punch press 1 to the work loading / unloading device 3. When the front end and the rear end of the work W are detected, the deburring device 43
The vertical movement and rotation drive and stop can be automatically performed.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. In this embodiment, a turret punch press was used as the plate processing machine, but other punch presses may be used.

[0039]

As will be understood from the above description of the embodiment, according to the present invention, a pair of vertically movable whetstone brackets with a lifting guide are provided on the plate material processing machine side of the main body frame of the work carry-in / out device. Since both sides of the grindstone are rotatably held by this, when the work after processing is carried out from the plate processing machine, burrs generated by the processing of the plate processing machine can be removed by the grindstone.

The pair of hoisting wheel brackets with lift guides rotatably support both sides of a shaft, and pinions provided on both sides of the shaft mesh with racks provided vertically. When the pair of lifting and lowering guide-equipped whetstone brackets is moved up and down, the whetstone can be held upright and moved up and down. Therefore, the grindstone can accurately contact the lower surface of the work, and burrs generated on the lower surface can be reliably removed.
