【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the lower side of FIG. 1, the rear means the upper side of FIG. 1, the left means the left side of FIG. 1, and the right means the right side of FIG. As shown in Fig. 1, the racks 1 and 1 are installed in parallel with each other in the left-right direction with a predetermined distance in front and back, and along two rails 11 and 11 laid between the racks 1 and 1 facing each other. The stacker crane 10 is provided so that it can move left and right, and the left and right moving passages of the stacker crane 10 face the parts extending to the right along the racks 1 and 1, respectively. The general flow of the vehicle 9 is that the car 9 that has entered the garage 25 is received by the stacker crane 10 and is stored in the racks 1 and 1, and The automobile 9 taken out from the racks 1, 1 by the stacker crane 10 is supposed to be driven off after being placed on the exit 27.

As shown in FIG. 2, the rack 1 has a plurality of parking shelves 2 vertically and horizontally, and each of the parking shelves 2 has a pair of left and right pallet bearing members 3, 3. A predetermined butting interval (an interval at which two slide forks 15, 15 described later can be slid back and forth and vertically moved) is maintained. A pallet 5 is placed on each of these parking shelves 2 regardless of whether or not a vehicle 9 is stored therein.

As shown in FIG. 3, the pallet 5 has tire receiving portions 6 provided at the four corners thereof, and each of the tire receiving portions 6 extends in the left-right direction (longitudinal direction of the automobile 9). A plurality of notches 7 that penetrate vertically are formed at predetermined intervals in front of and behind each other. The distance L between the centers of the tire receivers 6 and 6 along the left-right direction (longitudinal direction) of the pallet 5 is the axis of a vehicle having a standard size among the vehicle types of the vehicle 9 for which parking is accepted. The length of each notch 7 is determined so as to match the distance (wheel base) and include the largest to the smallest axial distance. In addition, the distance W between the centers of the tire receiving portions 6 and 6 along the front-rear direction (width direction) of the pallet 5 is the standard size among the vehicle types of the vehicle 9 for which parking is accepted. The notches 7 are formed so that the notches 7 are formed so as to include those having the largest wheel diameters and those having the smallest wheel distances.

As shown in FIG. 4, the stacker crane 10 includes a traveling base 12 for left and right movement, a pair of left and right masts 13 and 13 standing on the traveling base 12, and the masts 13, 13. It has a lift table 14 that can be lifted and lowered along it. A fork base 16 is provided on the lift base 14 and is laid over in the left-right direction while maintaining a predetermined height. Sliding forks 15, 15 are provided. A pantograph lifting device 17 (see FIG. 5) is provided below the fork base 16. The hoisting device 17 holds a horse 18 so as to be vertically movable with respect to a hoisting base 14. The horse 18 has a forked shape from a bottom plate portion 19 and both left and right end portions of the bottom plate portion 19. (See FIG. 5), the side walls 20 and 20 vertically penetrating the fork base 16 and the tire receiving base 21 (which horizontally extends from the upper ends of the side walls 20 and 20 so as to face each other in the left-right direction). There are four in total). As shown in FIG. 5, the tire pedestal 21 of the horse 18 has a plurality of comb teeth 23 arranged in the front and back through the notches 22 extending in the left-right direction. The pallets 5 (see FIG. 3) are arranged at the same intervals as the notches 7 of the respective tire receiving portions 6. Therefore, when the pallet 5 is pulled up on the lift base 14 by the slide forks 15 and 15 and the horse 18 is lifted by the lift device 17, as shown by the chain double-dashed line in FIG. Passes through each tire receiving portion 6 (notch 7) and floats upward.

As shown in FIG. 1, like the parking shelves 2 of the rack 1, the pallet 5 is placed on the garage 25 and the garage 27 from the beginning. In addition, when the elevator 14 of the stacker crane 10 is lowered to the lowest level, the yard 5 and the yard 27 are located in the pallet 5 rather than the height from the floor level to the upper surface of the slide fork 15. It has a pair of left and right pallet holders 26 and 28 so that it can be held at a high level (see FIG. 2). Reference numeral 30 is a slope used for going up and down to the entry hall 25 and the exit hall 27. However, contrary to this, if the left and right moving passages (see FIG. 1) of the stacker crane 10 are dug down from the floor level according to the above-mentioned height dimension, the entrance 25 and the exit 27 are removed. It is possible to make it flush with the floor level. By the way, if a turntable 29 is provided at either the entrance 25 or the exit 27 (the exit 27 in the drawing), it can be set so that when the vehicle 9 leaves the car, it can face forward and start running. It's convenient.

[0011]

[Operation of the Example Device]

 Next, the operation of the embodiment apparatus will be described. In FIG. 1, when a car 9 is loaded on the pallet 5 of the storage area 25, the stacker crane 10 travels to a position corresponding to the storage area 25 and stops, and then the elevator platform 14 moves up and down and the slide fork is moved. Skillfully combining the front and rear sliding of 15, 15, the automobile 9 together with the pallet 5 is pulled onto the lift table 14 (slide forks 15, 15). Then, as shown in FIG. 5, by raising and lowering the lifting / lowering device 17 in this state, all four tire pedestals 21 are synchronously raised on the lifting / lowering platform 14, and the automobile 9 is mounted on these tire pedestals 21. Be lifted. As a result, the pallet 5 is in an empty state with no upper part placed on it. Therefore, the slide forks 15 and 15 and the elevator 14 are operated in substantially the reverse order of the above, and only this pallet 5 is moved. Will be returned to the storage area 25.

The stacker crane 10 travels toward and away from the racks 1 and 1 by the lateral movement of the traveling base 12 (see FIG. 1), and moves the lifting platform 14 by a predetermined amount toward the predetermined parking rack 2. During the operation, the elevating device 17 is kept in the ascending motion. Then, when the stacker crane 10 faces the desired parking rack 2, the slide forks 15, 15, the lifting platform 14, and the tire receiving platform 21 are operated in substantially the opposite manner to be placed on the parking rack 2. The pallet 5 that has been used is temporarily pulled onto the lift 14 (below the car 9 that is being lifted and held), and then the car 9 is transferred onto the pallet 5 and the car 9 is parked together with the pallet 5. Store it in 2. As is clear from these explanations, the stacker crane 10 once retracts the pallet 5 from the garage 25, the garage 27, and the parking shelves 2 of the rack 1 and then immediately returns the pallet 5 to the original position. As a result, the pallet 5 does not stay in the overall flow, and the time required for returning does not include the horizontal movement of the stacker crane 10 and the vertical movement of the lifting platform 14. Therefore, the operating efficiency is extremely high.

By the way, the horse 18 (see FIG. 4) having the above-mentioned tire receiving base 21 is fixed to the elevating base 14 and, instead, a vertically movable base frame for holding the slide forks 15, 15 (fork described above). The same operation as above can be obtained by moving the holding table 16) instead of the holding table 16 up and down by the lifting device 17. It should be noted that in the tire receiving portion 6 of the pallet 5, the notch 7 may have an opening shape that is long in the front-rear direction. In addition, with respect to the mutual arrangement of the rack 1 and the stacker crane 10, for example, only the entrance 25 may be positioned on the right side of the rack 1 and the exit 27 may be positioned on the left side of the rack 1. It is also possible to use both the storage area 25 and the output area 27 as one, and dispose them at the lower center of the front rack 1 (not shown).
