DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a work reversing aligning and conveying apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.

1A to 1C, reference numeral 10 is used.
1 shows a work reversing alignment transfer device according to an embodiment of the present invention. The work reversing aligning and conveying device 10 is basically arranged in parallel with each other and a first
And the second and second conveyors 12, 14 and the first and second conveyors.
It comprises a reversing device 16 provided above the parallel running sections of the conveyors 12 and 14. The second conveyor 14 is located relatively lower than the first conveyor 12 via the slope portion 18. Thereby, the first conveyor 12 to the second conveyor 14
The work 20 is basically transferred by its own weight. The shape of the conveyed work 20 is a rod having a large-diameter portion 22 having one end larger than the small-diameter portion 21 (see FIGS. 2 and 3).

The reversing device 16 has a first claw 26 for locking the large-diameter portion 22 of the work 20 above the end 24 of the first conveyor 12. A proximity sensor 28 is provided for detecting the presence or absence of the work 20 to be performed. In this case, if the first claw portion 26 is configured to be slidable in the vertical and horizontal directions, it is possible to cope with the work 20 having various dimensions. A rotating unit 34 is provided so as to bridge between the end 24 of the first conveyor 12 and the start 25 of the second conveyor 14. The rotating portion 34 includes an arm 35 that is urged by the motor 30 about the shaft portion 32 and rotates 180 degrees, and a pair of second claw portions symmetrically provided on the arm 35 about the shaft portion 32. 36a, 3
6b. The second claw portions 36a, 36b have ends 38a, 38b formed with large diameters at their shaft ends.
Is provided. The large-diameter portion 22 of the work 20 is attached to the end 38a.
Are engaged, and the work 20 is inverted with the rotation of the arm 35. Further, a guide 39 having an inclined surface 39a inclined in the direction of the second conveyor 14 is provided so that the inverted work 20 does not jump out of the transport path.

The reversing device 16 includes a rotating part 34.
Is provided with a proximity sensor 40 for confirming the reversal of.

The work reversing and aligning and conveying apparatus 10 according to the present embodiment is basically constructed as described above. Next, the operation and effect of the apparatus will be described.

First, rod-shaped workpieces 20 aligned in the axial direction are individually carried into the first conveyor 12 by an unillustrated aligning / conveying device. The work 20 is conveyed by the first conveyor 12 urged by a driving device (not shown) to the terminal portion 24 of the first conveyor, that is, the reversing device 16. Here, when the large-diameter portion 22 of the work 20 is oriented in the traveling direction, the large-diameter portion 22 is locked by the first claw portion 26 of the reversing device 16 (see FIGS. 2 and 3). The proximity sensor 28 provided on the first claw portion 26 detects the large-diameter portion 22 and transmits a detection signal to the rotating portion 34. The rotating part 34
Then, the detection signal is received and the motor 30 is rotated.

At this time, the arm 35 rotates with the rotation of the motor 30, and the first claw portion 26 is moved to the large diameter portion 22 of the work 20.
Is pressed in the direction of arrow a in FIG. Due to this pressing force, the work 20 moves in the direction of arrow a, and is released from the locked state by the first claw portion 26. The work 20 tries to drop in the direction of the second conveyor 14 due to its own weight of the large-diameter portion 22, but the end 38 a of the rotating first claw 26 locks the small-diameter portion 21 of the work 20, and The work 20 is rotated together with the part 34. The work 20 has its small-diameter portion 21 formed by the centrifugal force of the work 20 itself.
Press

When the arm 35 rotates by 180 degrees, the proximity sensor 40 provided in the reversing device 16 detects the arm 35 and stops the rotation of the motor 30. When the rotation stops, the centrifugal force disappears, and the work 20 separates from the second claw portion 36a. Since the separation is performed by the weight of the work 20, it is not necessary to control the second claw portion 36a specially. The work 20 is guided by the guide 39 and the second
It falls on the conveyor 14. Next, the work 20 is continuously transported to the next process by the second conveyor 14 (FIG. 1).
A, see FIG. 1B and FIG. 2).

When the large-diameter portion 22 of the axially aligned rod-shaped workpiece 20 carried into the first conveyor 12 faces in the direction opposite to the traveling direction, that is, the small-diameter portion 21
Is facing the traveling direction, the workpiece 20 is the first claw portion 2
Before being locked to 6, it falls along the slope portion 18. Therefore, the work 20 is not locked by the first claw portion 26, and the proximity sensor 28 provided on the first claw portion 26 does not detect the large diameter portion 22 of the work 20. Eventually, the rotating unit 34 does not rotate (see FIG. 1C).

By the above operation, the workpieces 20 aligned in a predetermined direction are transported to the next process by the second conveyor 14.
