The operation of the automatic operation will be described with reference to a time chart shown in FIG. In FIG. 5, the horizontal axis indicates time t, and the vertical axis indicates each operation item.

When the automatic operation starts, first, the cutter drive motor 34 and the piston drive motor 74 rotate synchronously, and the workpiece 40 is fed into the cutter 30 via the forced supply arm 51 by the rotation of the cutter drive motor 34. Then, it is pulverized and fragmented by the cutter 30, sequentially discharged from the processing object discharge port 22 of the hopper 20, and put into the cylinder 61 through the opening 61 a of the cylinder 61 as shown in FIG. 6.
In addition, the forward rotation of the piston drive motor 74 causes the workpiece pressing piston 62 to sequentially move forward while pressing the workpiece 40 from the last retreat position.

At this time, the cutter driving motor 34 is set at the position where the object pressing piston 62 closes the opening 61a of the cylinder 61 (the limit switch LS3 is "ON", FIG.
The time set by the timer T1 until the point B)
It rotates forward and backward intermittently. That is, the motor rotates forward during the time TR1 and reverses during the time TR2 (<time TR1).

When the workpiece pressing piston 62 advances to a position where the opening 61a of the cylinder 61 is closed as shown in FIG. 7, the operating portion 62e of the workpiece pressing piston 62 comes into contact with the limit switch LS3. To operate the limit switch LS3. Then, the cutter drive motor 34 stops, but the workpiece pressing piston 62 is further moved forward by the piston drive motor 74 which rotates continuously and presses the workpiece 40 (see FIG. 8).

At this time, if the pressure of the cylinder 61 exceeds a predetermined pressure, that is, if the pressure applied to the workpiece 40 exceeds the predetermined value and the pressure applied to the workpiece pressing piston 62 exceeds the predetermined value, the workpiece 61 As shown in FIG. 9, the pressing piston 62 stops moving, that is, the nut 71 stops moving, and the threaded rod 72 retracts while compressing the urethane spring 79 via the stopper 75, and the operating part 75 b of the stopper 75 switches the limit switch LS <b> 5. , And the limit switch LS5 is turned “ON”, the piston drive motor 74 temporarily stops.

Thereafter, when the pressing force against the object to be processed 40 reaches a predetermined value, the resilient force of the urethane spring 73 returns the screw rod 72 to the old position. Then, the stopper 75
Is separated from the limit switch LS5, the limit switch LS5 is turned "OFF", and the piston drive motor 74 rotates forward again.

Here, when the limit switch LS5 is operated for the first time, the timer T3 starts to operate, and during the time TR3 (for example, 15 to 20 minutes) preset in the timer T3, the forward rotation of the piston drive motor 74 is started. And stop are repeatedly performed by the limit switch LS5.

When the timer T4 is turned "OFF", the piston drive motor 74 stops, and the discharge gate drive motor 82
Rotates forward, and the processed material discharge gate 63 rises.

As shown in FIG. 10, when the processed material discharge gate 63 reaches the highest position and the processed material discharge port 61b of the cylinder 61 is opened, the operating portion 63a comes into contact with the limit switch LS7 to limit the limit. When the switch LS7 is actuated (point D in FIG. 5), the discharge gate drive motor 82 stops, and at the same time, the piston drive motor 74 rotates forward again to move the workpiece pressing piston 62 forward and discharge the processed workpiece from the cylinder 61. The processed object 41 is put into the casing 91 from the outlet 61b.

As shown in FIG. 11, when the workpiece pressing piston 62 reaches the most advanced position, the operating portion 62e
Touches the limit switch LS4 to operate the limit switch LS4 (point C in FIG. 5).
Operates, and after the piston drive motor 74 stops for a time TR5 set in advance by the timer 5, the motor rotates reversely. As a result, the workpiece pressing piston 62 retreats, and when its operating portion 62e comes into contact with the limit switch LS3, the limit switch LS3 is activated, the piston drive motor 74 stops, and at the same time, the discharge gate drive motor 82 reversely rotates. The processed material discharge gate 63 is lowered.

Then, the processed material discharge gate 63 reaches the lowermost position, and its operating portion 63a is set to the limit switch LS.
6, the limit switch LS6 is activated, and the lowering of the processed material discharge gate 63 is stopped. At the same time, the piston drive motor 74 rotates in the reverse direction,
2, the limit switch LS2 is operated by the operating portion 62e, and the piston drive motor 7
4 stops. Thus, one cycle of the automatic operation is completed.

Further, when the automatic operation is continued, the operation of the limit switch LS2 causes the piston drive motor 74 to start forward rotation, and the cutter drive motor 34 rotates forward and backward for the time set in the timer T1, and so on. The cycle is repeated. As described above, the operation of the apparatus of the present invention has been described as the operation start position on the left end of the time chart in FIG. 5 for convenience. However, it is needless to say that the operation can be started or stopped at an arbitrary position.

During the automatic operation, when a processed object 41 having a predetermined weight or more is loaded into the casing 91, the casing 91 rotates clockwise about the roller 97 as a rotation center, thereby The measuring lever 93 of the measuring means 92 rotates counterclockwise against the spring force of the tension spring 94, and the measuring lever 93 comes into contact with the limit switch LS8 and the limit switch LS.
8, and the automatic operation stops. Then, when the casing 91 filled with the processed material 41 is taken out of the machine casing 10 and the empty casing 91 is stored at a predetermined position in the machine casing 10, automatic operation can be performed again.
