[0016]

As described above, according to the automatic warehouse facility of the present invention, of the two warehouse units arranged side by side, the loading and unloading operation for the warehouse unit on the side equipped with the elevating and conveying device is the same as in the prior art. In addition, the elevating and lowering transfer device can be used to transfer the load between the loading and unloading conveyor and the load transfer part of the load transfer traveling vehicle corresponding to the loading and unloading level in the rack. For loading and unloading work for the other warehouse unit that does not have the above-mentioned equipment, the above-mentioned lifting / lowering transport is used to transport the load between the loading / unloading conveyor and the loading / unloading part of the loading / unloading carriage corresponding to the loading / unloading level in the rack. This can be performed without trouble by using the device and the relay load transfer table corresponding to the loading / unloading level among the upper and lower relay load transfer tables adjacent to the elevating path.

As described above, according to the configuration of the present invention, one elevating / conveying device attached to one of the warehouse units also serves as the elevating / conveying device required for the loading / unloading operation for the two warehouse units arranged in parallel. Therefore, the entire equipment can be constructed at a low cost as compared with the conventional configuration in which both the warehouse units are provided with the expensive and large-scale lifting and lowering transporting device.

Further, in the structure of the present invention according to claim 2, the load transfer traveling trolley used in both the warehouse units has a load transfer section that moves forward and backward to the left and right sides. Using a conventional well-known general one that has a running fork that can be moved up and down, by the running fork,
It is possible to perform load transfer to and from the elevating load transfer table of the elevating and lowering transfer device and each stage relay load transfer table, and The transfer of the load to and from the relay load transfer table can be performed by a transfer drive conveyor provided so as not to interfere with the advancing / lowering movement of the running fork. Furthermore, by raising the elevator conveyor provided on the elevator transfer table to the upper level, the elevator conveyor can be used to connect the elevator conveyor between the elevator transfer device and the loading / unloading conveyor. Transfer of cargo can be done automatically.

That is, according to the automatic warehouse equipment of the present invention according to claim 2, one elevator transport device required for loading and unloading work for two warehouse units arranged in parallel is also used as one. The apparatus of the present invention can be implemented easily, easily and inexpensively without using a special load transfer means for pushing and pulling a load.
