【Example】

 An embodiment of this invention will be described with reference to FIGS. This unloading device is configured to carry out a product processed by a turret type single-spindle lathe 1, and is provided between a processing space 2 in which a spindle 1a and a turret 10 are arranged and an unload conveyor 3. Are partitioned by a partition cover 4. The lathe 1 has a long rod-shaped material Wa penetrating from the rear into the main spindle 1a, and the portion protruding forward from the main spindle 1a is processed by the tool of the turret 10, and the rod-shaped material Wa is projected to a predetermined size after the processing is completed. The product W is cut into pieces and cut into pieces.

The partition cover 4 has a product take-out window 5 formed in the upper part thereof. The processing space 2 is provided with a parts catcher 6 that receives the product W processed by the lathe 1, conveys it to the product extraction window 5, and inputs it to the unload conveyor 3 side. This parts catcher 6 is configured such that a rotation drive mechanism 9 rotates an approximately L-shaped arm 8 having a semi-cylindrical container 7 for receiving the processed product W at its tip pivotably pivotally attached. It is a thing. By this rotation of the arm 8, the container 7 moves between a position for receiving the processed product W on the spindle 1 a of the lathe 1 and a position for covering the product take-out window 5 of the partition cover 4.

A guide rod 11 for attitude control is provided outside the container 7 for receiving the product W. On the other hand, at a position on the moving path of the guide rod 11 close to the product taking-out window 5, the rod comes into contact with the guide rod 11 and changes the posture of the container 7 to the posture of covering the product taking-out window with the rotation of the arm 8. A regulating member 12 is arranged.

A shutter 13 for closing the product take-out window 5 of the partition cover 4 from the unload conveyor side is rotatably supported by a support shaft 14 provided at the upper edge of the product take-out window 5. There is. Further, a weight 15 is provided above the shutter 13 for constantly urging the shutter 13 in the closing direction. A guide plate 17 that forms a dropping guide path 16 for the product W together with the partition cover 4 is arranged between the product take-out window 5 and the unload conveyor 3 therebelow.

The operation of the unloading device having the above configuration will be described with reference to FIGS. 1 and 2. The rod-shaped material Wa of the product W is gripped by the main spindle 1a of the lathe 1 and processed by the tool attached to the turret 10. At this time, the arm 8 of the parts catcher 6 is retracted to the rotation position shown by the chain line in FIG.

When the processing is completed and the processed product W is cut off from the bar-shaped material Wa, the arm 8 of the parts catcher 6 is rotated counterclockwise by the rotation drive mechanism 9 from the standby position shown by the chain line in FIG. When the semi-cylindrical container 7 is rotated in the direction, the semi-cylindrical container 7 moves to a position below the processed product W held by the main shaft 1a and stops there. In this state, the processed product W is cut off. During this time, the product take-out window 5 of the partition cover 4 is not covered by the container 7 of the parts catcher 6, but is closed by the shutter 13. That is, the moment of the weight 15 urges the shutter 13 from the unload conveyor 3 side in the direction of closing the product take-out window 5. In this way, with the simple structure that only the weight 15 is provided, the closed state of the product take-out window 5 is maintained, and the chips and cutting oil generated at the time of cut-off are transferred from the product take-out window 5 to the unload conveyor 3 side. Intrusion is prevented.

The processed product W cut off from the gripped portion by the spindle 1 a is received by the semi-cylindrical container 7 of the parts catcher 6. Then, the arm 8 of the parts catcher 6 rotates clockwise in FIG. When the container 7 approaches the product take-out window 5 of the partition cover 4, the guide rod 11 of the container 7 is regulated by the rod regulating member 12, and as the arm 8 advances, the container 7 is placed in the posture of covering the product take-out window 5. be changed.

As a result, the product W contained in the container 7 is discharged to the product take-out window 5 by its own weight. Due to the weight of the product W, the shutter 13 closing the product take-out window 5 is pushed against the moment of the weight 15 and the product take-out window 5 is opened. That is, the moment of the weight 15 is set in advance so as to be smaller than the force by which the product W pushes and opens the shutter 13 by its own weight. In this way, the product W is dropped from the product take-out window 5 to the unload conveyor 3. The dropped product W is carried out by the unload conveyor 3.

FIG. 3 and FIG. 4 are longitudinal sectional views showing the essential parts of another embodiment of the unloading device of the present invention. In this embodiment, an elastic plate material 18 such as a plate spring is used as a means for constantly urging the shutter 13 against the product take-out window 5 of the partition cover 4 from the unload conveyor 3 side in the closing direction. That is, the upper side of the shutter 13 is connected to the upper edge of the product take-out window 5 via the elastic plate member 18. Other configurations are similar to those of the previous embodiment, and therefore their explanation is omitted here.

In this embodiment, when the container 7 of the parts catcher 6 that has received the processed product W has moved to the rotation position where the product take-out window 5 is covered as shown in FIG. 4, the container 7 is moved by its own weight. The product W discharged from the shutter 13 pushes the shutter 13 toward the unload conveyor 3 side against the restoring force of the elastic plate member 18. As a result, the product W is dropped onto the unload conveyor 3 from the product take-out window 5.

In each of the above-described embodiments, the shutter 13 is pushed open by the product W discharged from the container 7 of the parts catcher 6 by its own weight. However, the invention is not limited to this. For example, the container 7 of the parts catcher 6 can be opened. A pressing rod or the like that pushes and opens the shutter 13 may be provided so as to project, and the shutter 13 may be directly pushed and opened regardless of the product W. With this configuration, the moment of the weight 15 in the first embodiment that normally biases the shutter 13 and the restoring force of the elastic plate material 18 in the second embodiment are pushed by the weight of the product W. There is no need to consider setting the pressure lower than the pressure.
