Next, the operation will be described.

The articles W transported from the outside are transferred from the loading / unloading conveyor 24 to the elevator loading / unloading machine 27, and are raised by the elevator loading / unloading machine 27 to the shelf 21 having the desired storage frame 25. Then, the article W is transferred to the waiting conveyance / transfer vehicle 23 via the moving table 28. The transfer is performed by moving the moving bodies 41, 41 moved by the transfer motor 35 of the transport / transfer vehicle 23 into the moving table 28.

The transporting / transferring vehicle 23 that has received the article W pulls the moving body 41 back onto the frame 36, moves to the front of the desired storage frame 25, and stops.

After that, the transfer motor 35 causes the pair of moving bodies 41, 41 to enter the storage frame 25, and conveys / transfers the article W engaged with the picking pins 42, 42 protruding from the pair of moving bodies 41, 41. Transfer from the vehicle 23 to the shelf 21. The articles W to be transferred from the transfer / transfer vehicle 23 to the shelf 21 are provided on the guide plate 44 on the transfer / transfer vehicle 23.
And the guide plate 26 on the shelf 12 to guide and transfer. Therefore, the direction of the article W does not change during transfer,
Transfer of the article W is smoothly performed. Furthermore, the transport / transfer vehicle 23 may stop a little too far from the front of the storage frame 25,
Alternatively, even if it stops before the storage frame 25 and the transport / transfer vehicle 23 stops at the wrong position, the guide plate 26 of the shelf 21 stores the article W in the predetermined position of the shelf 21, When it is next carried out, it is smoothly transferred to the transfer / transfer vehicle 23.

Further, when the article W is transferred from the transporting / transferring vehicle 23 to the shelf 21, the article W passes over the rail R, but since the rail R is covered with the cover 46, the article W moves without touching the upper surface of the rail R. To be made. Further, even if a part of the bolt 39 is projected on the upper surface of the rail R in front of the storage frame 25 or the connection plate 40 is attached, the cover 46
Covers the upper surface of the bolt 39 and the connecting plate 40, the article W is moved to the shelf 21 without contacting the bolt 39 and the connecting plate 40.

Therefore, the top surface of the rail R and the bottom surface of the article W are not scratched.

The transporting / transferring vehicle 23 that has transferred the article W on the shelf 21 retracts the picking pin 42, releases the engagement with the article W, and then pulls the moving body 41 back onto the frame 36.

When the article W is unloaded from the shelf 21, the moving body 41 is advanced into the shelf and the picking pin 42 is engaged with the article W. Thereafter, the moving body 41 is returned to the frame 36 so that the articles W are loaded on the transport / transfer vehicle 23. After that, the transport / transfer vehicle 23 travels the article W to another storage frame 25 or the moving table 28.

Effects of the Invention The article transfer guide structure of the present invention has the following effects because the cover covers the upper surface of the rail laid at a position lower than the shelf.

Since the rails can be laid at a position lower than the upper surface of the shelves, the transport / transfer vehicle can be stored in the space between the shelves and the height of the entire storage shelves can be reduced.

There is no connecting part other than between the transporting / transferring vehicle and the cover, and items can be transferred smoothly, and
The chance of giving vibration to the article is reduced, and damage to the article can be prevented.

When transferring goods, since the goods pass on the top surface of the rail without touching them, the surface treatment film (generally paint) applied to the rail is not peeled off and the bottom surface of the goods is cleaned for a long time. Can be kept at

Even if a protrusion such as a part of a bolt or a rail connecting plate is projected on the rail upper surface, the protrusion is also covered by the cover, so that the protrusion can be freely provided on the rail.

When the guide plate is provided as in claim 2, the orientation of the article does not change when the article is transferred.
Transfer can be smoothly performed between the transfer vehicle and the shelf.

Further, when the guide plate is provided as in claim 2, the article is stored in a predetermined position on the shelf even if the stop position of the transport / transfer vehicle may be misaligned. When the article is carried out, it can be smoothly transferred to the transfer / transfer vehicle.
