A rod 10 is erected above the check gauge 8.

Reference numeral 11 denotes a column, which is erected on the base 12, and a support box 13 is fixedly installed on the top of the column.

Inside the support box 13, a first limit switch is arranged corresponding to each step of the step-like recess 8a of the check gauge 8, thereby forming a first limit switch group 14.

The first limit switch group 14 detects the relative contact position between the check gauge 8 and the drive pinion a.

That is, each first limit switch of the first limit switch group 14 corresponds to each step portion of the check gauge 8 on a one-to-one basis.

Reference numeral 15 denotes a check cylinder, which is fixedly installed outside the support box 13.

A rod 10 of the check gauge 8 is inserted into a support box 13 so as to be vertically movable.

A connecting plate 16 connects the tip of the piston rod 15a of the check cylinder 15 and the upper end of the rod 10 of the check gauge 8.

The rod 10 is free with respect to the connecting plate 16.

Reference numeral 10a denotes a protrusion provided on the rod 10, which comes into contact with a contact of a predetermined first nomit switch (corresponding to the main body b of the drive pinion a) when the rod 10 descends.

Reference numeral 17 denotes a guide rail having a U-shaped cross section, and is fixed on the base frame 7 fixed to the base 12.

Both are inclined to become lower as the distance from the guide rail 17 increases.

Reference numeral 20 denotes a second limit switch, which is disposed on the cover member 9 of the transport vehicle 5 on the side opposite to the check position with respect to the guide rail 17, so that the receiver 4 corresponds to the socket 19a of each carry-out chute 19. , which constitutes a second limit switch group.

A projecting piece 21 is fixed to the cylinder body of the lifting cylinder 6, and is positioned so as to come into contact with each contact of the second limit switch 20 when the receiver 4 (transport vehicle 5) moves.

Reference numeral 22 denotes a support plate, which is fixed to the lower side of the transport vehicle 5, and an upper chain 23 is attached to the lower surface of the support plate 22.

On the other hand, a lower chain 24 is also attached to the base 12 in correspondence with the upper chain 23, and a sprocket 25 is meshed with both chains 23,24.

The sprocket 25 is rotatably attached to the piston rod 26a of the transport cylinder 26, and moves the transport carriage 5.

In the above structure, the support plate 22 (carrying carriage 5) to which the upper chain 23 is mounted moves twice the distance that the sprocket 25 moves relative to the lower chain 24.

Furthermore, a control circuit (not shown) is provided that connects the first limit switch of the first limit switch group 14 and the second limit switch 20 of the second limit switch group, respectively, so as to operate the sorting device. is controlled.

In addition, 27.27 is a cylinder that operates the guide members 3, 3 of the horizontal portion 2a of the carry-in chute 2.

Reference numeral 28 denotes support legs that support the socket 19a of the carry-out chute 19 on the base frame 7.

Next, the operation of the above device will be explained. First, the drive pinion a is conveyed along the carry-in chute 2 to the check position.

At this time, the shaft portion C of the drive pinion a is guided by the guide members 3, 3, and is supported at the check position.

Subsequently, the check cylinder 15 is activated, and the check gauge 8 is lowered and wraps around the horizontal portion 2a of the carry-in chute 2 through the slit 8b.

One of the stepped portions of the recess 8a of the check gauge 8 fits into the main body b of the drive pinion a, and the check gauge 8 no longer descends.

That is, since the rod 10 of the check gauge 8 is free with respect to the connection plate 16, even if the check cylinder 15 is activated, only the connection plate 16 will be lowered.

The check gauge 8 (rod 10) does not move, and at that time, the protrusion 10a of the rod 10 moves to the predetermined first limit switch, that is, the first limit switch corresponding to the stepped part of the check gauge 8 fitted to the main body b of the drive pinion a. 1 Activate the limit switch.

At the same time, only the corresponding second limit switch 20 is controlled to be operable by the signal from the first limit switch.

Subsequently, the check cylinder 15 is moved upward to move the check gauge 8 upward.

Subsequently, the soil holding cylinder 6 is operated to move the receiver 4 upward, and the shaft portion C of the drive pinion a is inserted into the support portion 4b of the receiver 4, and the drive pinion a is moved by the receiver 4.
The lower end of the shaft portion C is lifted up to a position slightly above the upper edge of the horizontal portion 2a of the carry-in chute 2.

After that, the conveying cylinder 26 is activated, and the sprocket 2
5 rotates to move the carriage 5 in the S direction (first
(see figure).

The carriage 5 moves with the support 4 holding up the drive pinion a.

In this way, the carriage moves, and the protruding piece 21 of the carriage 5 is brought into contact with the contact of the second limit switch 20 corresponding to the first limit switch activated at the time of checking among the first limit switch group 14. The second limit switch 20 is activated.

At this time, the operation of the conveying cylinder 26 is immediately stopped by the signal from the second limit switch 20 (each second limit switch 20 and the socket 19a of each unloading chute 19 correspond, so the predetermined unloading Socket 1 of chute 19
9 The receiver 4 is stopped directly above a).

Subsequently, the lifting cylinder 6 is operated to lower the receiver 4 and lower the drive pinion a.

Then, the main body b of the drive pinion a moves to the unloading chute 1.
When the support 4 further descends and reaches the bottom dead center, the engagement between the shaft portion C of the drive pinion a and the support portion 4b of the support 4 is released, and the drive Pinion a becomes free.

Thus, the drive pinion a slides down the carry-out chute 19 due to the action of gravity and is stored.

Further, the receiver 4 that has reached the bottom dead center passes through the lower side of the socket 19a of each carry-out chute 19 and returns to the original check position by the operation of the transport cylinder 26.

At this time, a new drive pinion a has already been supplied to the check position through the carry-in chute 2 by a supply means (not shown), and the drive pinion a is subsequently sorted in the same manner.

Further, in the above embodiment, the first limit switch group is attached to the support box 13 side, and the rod 10 is provided with the protrusion 10a that activates the first limit switch group. Of course, a protrusion may be provided on the support box 13 side, or the check gauge 8 may be fixed, the first limit switch group and the protrusion may be arranged on the receiver 4 side, and the receiver may be moved up and down. The mounting position thereof is not particularly limited as long as the relative contact position between the check gauge 8 and the drive pinion a (shafted article) can be detected.

As mentioned above, this invention mechanizes and automatically sorts products with shafts such as drive pinions based on the diameter of their bodies, which was previously done manually, resulting in extremely efficient sorting. This has an excellent practical effect of saving labor.

Furthermore, since the present invention has a simple circuit in which each first limit switch and each second limit switch correspond to each other, it has the advantage that failures are rare and repairs are easy.
