The stop lever 62 is rotatably pivoted at the middle part of the stop lever 62, and the stop pins 63 of the hanger wheels 9 are provided to protrude inward from the inner surfaces of the lower ends of the front stop levers 62 on both sides. be.

Next, the operation of this embodiment will be explained.

The conveyed object A that has been traveling on the inclined carry-in rail 1 has its hanger wheels 9 locked by the locking pin 63 of the front locking lever 62 of the conveyed object stopper device 53, and then stops once and waits. .

During this time, the transfer device 14 on the carry-in side is pulled back to the position of the carry-in rail 1 by the traveling driving chain 45 connected to the traveling frame 17, and at this position, the piston rod 29 of the air cylinder 27 is pushed out to move the movable rail 24. Connect to loading rail 1.

At this time, the upper and lower guide pins 31 and 32 on the movable rail 24 side
The tip of the guide pin 31 is conical and pointed.
32 fits into the opposing guide boss 33 and the circular pipe 5, even if there is some deviation in the driving stop position of the travel drive cheno 45, the movable rail 24 and the travel frame 17
are integrally adjusted and moved to accurately align the circular pipes 5, 23 of the opposing rails 1, 24.

This is because the alignment shaft 47 to which the chino 45 is directly connected is connected to the traveling frame 1 through the front and rear coil springs 50 and 51.
It is elastically held by support parts 25 at the front and rear of the frame 7, and can move forward and backward relative to this support part 25, so that even if the travel drive cheno 45 and the alignment shaft 47 integrated therewith do not move, the travel frame 17 and a movable rail 24 integrated therewith
This is because the adjustment movement can be carried out without difficulty.

When the carry-in rail 1 and the movable rail 24 are connected together in this way, it is detected by an IJ Mitswitch or the like, and the air cylinder 56 of the conveyed object stopper device 53 is activated.
The piston rod 57 can be retracted.

As a result, the locking pin 60 of the rear locking lever 58 descends and locks the hanger wheel 9 of the following conveyed object A, and the locking pin 63 of the front locking lever 62 rises and locks the object. Release the transported object A.

As a result, the conveyed object A moves from the inclined carry-in rail 1 to the movable rail 24 by itself, and moves onto the movable rail 24.
It is locked to the movable rail 24 by a locking pin 40 of the locking lever 38 provided at the left end and a non-return claw 42 provided at the right end.

Next, operate the air cylinder 27 to move the movable rail 24.
is moved to the neutral position, the traveling frame 17 of the transfer device 14 is pulled and moved to a predetermined position of the storage rail 3 by the traveling drive cheno 45, and the air cylinder 27 is operated at that position to move the movable rail 24 to the storage rail 3. Connect to rail 3, at that time,
Both rails 24
3 alignment is performed, and in this state, the piston rod 36 of the air cylinder 35 on the movable rail 24 is retracted to release the conveyed object A from its locking pin 40.

As a result, the conveyed object A transfers from the movable rail 24 to the storage rail 3 by its own weight, further moves by itself on this storage rail 3, is stopped by the conveyed object stopper device 53 at the left end, and is transferred to the unloading side. It is transferred from the storage rail 3 to the carry-out rail 2 by the loading device 14 in the same manner as described above.

As described above, according to the present invention, the movable rail provided on the traveling frame has two positions: a neutral position where both ends of the movable rail are separated from fixed rails on one side and the other side, a one-side position where one end is connected to the fixed rail on one side, and another position. Since the above-mentioned traveling frame is provided with a movable rail drive device that moves forward and backward across the other side position where the end is connected to the fixed rail at the other end, the transfer between the fixed rails located on the - side and the other side is carried out by one set of movable rails. It can be done smoothly through.

In addition, positioning means are provided on the opposite sides of the fixed rail side and the movable rail side on the - side and the other side, and a buffer material is interposed between the running frame and the external drive means for forcibly moving the running frame. With this cushioning material, even if there is a slight deviation in the stopping position of the traveling frame by the external driving means, the traveling frame and the movable rail can be forcibly aligned to the fixed rail position by the positioning means, and the outside There is a self-aligning effect while the drive means is stopped.
