DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG.
Is a horizontal train traveling route arranged in parallel in a plurality of upper and lower stages, and an entrance / exit train 3 is arranged in each stage train traveling route. Reference numeral 4 denotes a loading / unloading elevating transport device, and reference numeral 5 denotes a loading / unloading conveyor.

As shown in FIGS. 2 and 3, each of the train running routes 1 a to 1 i is formed between the shelves 2, and each of the train running routes 1 a to 1 i is supported by the left and right shelves 2. Guide rails 6 and 7 having a substantially L-shaped cross section are provided. On the horizontal rail portion 6a of one guide rail 6, a secondary conductor 9 in the linear motor type driving means 8 is laid, and on the horizontal rail portion 7a of the other guide rail 7, there is no contact. Taxiway (Litz wire) 1 in power supply means 10
1a and 11b are laid along the rail length direction in a state where they are arranged side by side in the left-right horizontal direction.

In each entry / exit train 3, a linear motor body (coil) 12 in a linear motor type driving means 8 is disposed so as to face the secondary conductor 9 on the guide rail 6 side. In addition, a pair of front and rear induction coil units 13a and 13b in the non-contact power feeding means 10 are provided. Each of the induction coil units 13a and 13b is composed of an induction coil 14 and a coil yoke 15 located between the guide paths 7a and 11b on the guide rail 7 side.

Further, the train 3 for entering and leaving the vehicle has wheels 16 rolling on the upper end surfaces of the vertical mounting portions 6b and 7b of the guide rails 6 and 7, and the vertical mounting portions 6b and 6b of the both guide rails 6 and 7.
7b is provided with a positioning vertical shaft roller 17 which abuts on the upper inner vertical surface, and transfers the load W between the load support 18 of the shelf 2 and the load support 19 of the loading / unloading train 3 on the upper portion. The transfer means 20 is provided. The load supporting portion 18 of the shelf 2 is an area partitioned by the partition member 22 on the load receiving plate 21.

Guideways 11a and 11b on the guide rail 7 side
A high-frequency current is supplied to the vehicle to generate a magnetic field around it, so that an electromotive force is generated in the induction coil 14 on the entrance / exit train 3 side, and power is transmitted to the entrance / exit train 3. By feeding power to the linear motor main body (coil) 12 with this electric power, a thrust acts on the train 3 for entrance and exit by the magnetic action between the secondary conductor 9 on the guide rail 6 side, and the train 3 for entrance and exit is generated. The vehicle travels along the guide rails 6 and 7 in a predetermined direction.

Thus, as shown in FIG. 1B, a pair of taxiways 11a and 11b in each of the train traveling routes 1a to 1i are
One end of the train traveling route is connected to each other in series. On the other hand, each stage train traveling route 1a to 1i is divided into upper and lower blocks A to C each including a plurality of upper and lower stages (three stages in the illustrated example), and trains of upper and lower stages in the same block. The guideways 11a and 11b of the route are connected in series with each other at the other end of the train travel route and connected to one of the power supply panels 23a to 23c. Each of these power panels 23
a to 23c may be mounted at the levels corresponding to the blocks A to C of the shelf 2, but may be collectively installed on the ground side as indicated by phantom lines. In addition, the number of stages of the train traveling routes belonging to each of the blocks A to C is considered so that the total length of the guideways 11a and 11b connected in series in each block is not so long as to reduce the induced electromotive efficiency. You can decide.

In the above-described embodiment, the automatic warehouse in which the traveling route of the loading / unloading train 3 is provided for each stage loading support level of the shelf has been described. A stacker crane type equipped with a lifting carriage capable of supporting a plurality of upper and lower load support levels may be used.

[0012]

The power supply device of the present invention can be implemented as described above. According to the device of the present invention, the guideway for contactless power supply laid on the train travel route is provided. Instead of connecting to the power supply panel for supplying high-frequency current separately for each train traveling route, it is connected to one power supply board with the guide paths of the upper and lower train traveling routes connected in series with each other. Therefore, the number of power supply panels can be reduced to achieve a significant cost reduction. Further, the cost required for the work of wiring the power supply to the power supply panel can be reduced.

Of course, the taxiways laid on the train travel routes of all the stages may be connected in series. However, as shown in the embodiment, the train travel routes are each divided into a plurality of upper and lower train travel routes. When the taxiways of the upper and lower train running routes are connected in series to each other and connected to one power panel, a large automatic warehouse is used. Even if the total length of the train travel route in the warehouse is very long, the disadvantage is that the total length of the taxiway connected to one power panel is too long, and the efficiency of wireless power supply to the train is reduced. The cost can be reduced without accompanying.
