In the figure, 52 indicates a control panel, 53 indicates a rotation warning light, and 54 indicates a base plate for supporting the conveyed object a. They are provided on both sides of the conveyor 1 in parallel to the conveyor 1. Note that a indicates a cylindrical object to be transported.

In such a configuration, when a cylindrical object a is placed upright on the conveyor 1 and the object a is conveyed by the conveyor 1, the clamp body 1
In this case, the clamp fork 21 at 9 is
In the open state, it is waiting for the transported object a, so that the transported object a first comes into contact with the contact frame 33 and the stopper body 47, and its movement is stopped. In this case, the stopper body 47 is
It acts to prevent the conveyed object a from falling down due to the conveying force of the conveyor 1, thereby maintaining the upright state of the conveyed object a.

In this state, the clamp drive cylinder 2
6 actuates, the clamp fork 21 closes via the link motion of the interlocking rod 24, and as a result, the outer ring 31 of each cam clutch 28 is pressed against the outer peripheral surface of the transported object a.

At the same time, the operating rod 16 of the lifting drive cylinder 15 is activated, and the clamp body 19 moves up along the support columns 10 on both sides while holding the conveyed object a via the clamp fork 21, and then the turning gear motor 17 As a result of the operation, it turns to one side about the turning shaft 18, and then stops after turning at a right angle.

When the clamp body 19 rises, the transported object a
Each of the cam clutches 28, which are in contact with the cam clutches 28, acts to prevent the transported object a from slipping down due to its weight.

The clamp body 19, which has risen and rotated while holding the conveyed object a, holds the conveyed object a on one side of the base plates 54 provided parallel to the conveyance path of the conveyor 1. It stops in a state located above the base plate 54 and then descends, whereby the conveyed object a is supported on the surface of the base plate 54. In this case, even if the clamp body 19 further descends after the transported object a reaches the surface of the base plate 54, the outer ring 31 of each cam clutch 28
Due to this action, the transferred object a is transferred without damaging the transferred object a.

That is, when the clamp body 19 attempts to descend further after the transported object a has arrived at the surface of the base plate 54, the outer ring 31 of the cam clutch 28 rotates in a rotatable direction. Only the clamp body 19 will be lowered along the line.

When the conveyed object a is transferred onto the surface of the base plate 54 in this way, the clamp fork 21 opens,
The clamp fork 21 is opened and the conveyed object a is released from clamping, and in this state, the pusher gear motor 42 is operated.

As the pusher gear motor 42 operates, rotational force is transmitted to the transmission shaft 39 on one side, and the transmission shaft 39 on the other side also rotates via the transmission chain 41. The advancing/retracting frame 36 advances toward one side while being guided by the guide stand 35, and the pushing frame 37 on one side
The conveyed object a on the base plate 54 is pushed through the base plate 54, and the conveyed object a is pushed into a rail (not shown) of a stocker layer connected to the base plate 54.

In this way, in a state where the predetermined conveyed object a is pushed into the predetermined rail of the stocker, the clamp body 19 returns to the upper position and returns to its rotational state, and the pusher 34 returns to the standby position, and the next It will be prepared for transferring the transported object a.

The above-mentioned series of operations are performed continuously and periodically, and the objects a to be conveyed sequentially on the conveyor 1 at intervals are each pushed into a predetermined rail of the stocker. Frame 5
travels along the rail 2 and stops at a predetermined position, so that the transported object a is pushed into a selected rail on a stocker layer connected to the base plate 54.

Further, the bumper 51 and the phototube 49 are
It acts to detect whether there are any obstacles on the traveling path of the traveling frame 5, and in particular, the photocell 49
acts to detect whether the conveyed object a is present in the clamp fork 21 section or whether the conveyed object a is not carried in when the clamp fork 21 turns, based on the presence or absence of light shielding. and controls the traveling of the traveling frame 5.

In addition, in the above embodiment, the clamp body 19
Although an example is shown in which the device A and the device of the pusher 34 are configured separately, it is also possible to integrate these devices, and in the operation of the clamp body 19, the conveyed object a is clamped, raised, After turning and lowering, it is also possible to adopt a method in which the clamp fork 21 itself is moved back and forth, or a method in which the entire clamp fork 21 is moved back and forth to push the conveyed object a into a predetermined position and then the clamp fork 21 is opened.

Further, in the above embodiment, the clamp body 19
Although the direction of rotation of the clamp body 19 and the direction of advancement of the pusher 34 are directed toward the base plate 54 on one side, the rotation of the clamp body 19 and the direction of advancement of the pusher 34 are also directed toward the base plate 54 on the other side. Of course.

According to the present invention, the conveyed object conveyed by the conveyor is clamped by the clamp body, rises and turns, and then descends, is supported on the base plate, and is unclamped, and in this state The clamp body is pushed by a pusher into a predetermined rail on the stocker, and in this case, since the clamp body is installed on a traveling frame, the clamp body is moved by running the traveling frame along the conveyor. The clamped conveyed object can be accurately pushed into the selected predetermined rail, and by automatically repeating this series of operations, multiple conveyed objects can be conveyed sequentially on the conveyor. To provide a transfer device that can easily sort and push objects into each rail, thereby sequentially and quickly sending objects to be conveyed by a conveyor into predetermined rails in a stocker. become.
