There is a slight gap between the carriages 40A, 40B suspending A, 2B and the vehicle support base receiving frame 46 (see FIG. 5), and the laterally movable vehicle supports 2A, 2B can be moved sideways. it can.

As shown in FIGS. 1 to 3, the laterally movable vehicle supports 2 A and 2 B located at the lower vehicle support level D are:
The vehicle can be taken in and out regardless of its position. The loading / unloading of the vehicle with respect to the lifting / lowering vehicle supports 1A to 1C starts by lowering the lifting / lowering vehicle support of the lifting / lowering vehicle supports 1A to 1C to the lower vehicle support level D. Just below the lift vehicle supports 1A to 1C to be lowered to the lower vehicle support level D, the laterally moving vehicle support 2
If A or 2B is present, the laterally-moving vehicle support 2
A or 2B must be moved sideways to make the space directly below the lift vehicle supports 1A to 1C to be lowered to the lower vehicle support level D empty.

As shown in FIG. 2, in order to lower the elevating vehicle support 1B, only the laterally moving vehicle support 2B directly below the elevating vehicle support 1B is moved to the position directly below the elevating vehicle support 1C. When the traction unit 5 shown in FIG.
In a state where the pusher 66 of FIG. 4 is in the initial position where it does not engage with the pressed plate 68 of the laterally movable vehicle support 2A (the carriage 40A) as shown in FIG. The pinion gear 52 is driven to rotate in the forward direction by the motor 53 of the means 50, and the bogie 40B suspending the laterally movable vehicle support 2B with the propulsive force generated by the engagement with the rack gear 51 on the frame F side is moved to the front side shown in FIG. Through the pair of positioning / supporting guide rails 41 and left and right grooved wheels 42 and the rear supporting guide rails 43 and the left and right wheel units 44a and 44b (four wheels 45) to a position directly below the ascending and descending vehicle support base 1C. Just move it sideways.

In order to lower the elevating vehicle support 1A,
When the two laterally moving vehicle supports 2A and 2B, which are located directly below the ascending and descending vehicle supports 1A, 1B, are moved to the position directly below the ascending and descending vehicle supports 1B, 1C, the traction means 5 shown in FIG.
The rotary shafts 59 and 62 are driven to rotate by a predetermined angle by the motor 60, and the pusher 66 is engaged with the pressed plate 68 of the laterally-moving vehicle support base 2A (the bogie 40A) as shown by a virtual line in FIG. Switch to working position. Thereafter, when the self-propelled driving means 50 of the laterally movable vehicle support 2B is operated as described above to laterally move the laterally movable vehicle support 2B to a position directly below the vertically movable vehicle support 1C, the free end becomes a trolley. The rotating shafts 59 and 62 that move integrally with the laterally-moving vehicle support base 2B while being suspended from the trolley guide rail 65 via the center 64.
The pusher 66 in the vicinity of the free end pushes the laterally moving vehicle support 2A through the pressed plate 68 engaged with the pusher 66, and the laterally moving vehicle support 2A is driven by the self-propelled driving means 50. As a result, the vehicle moves laterally together with the self-propelled laterally moving vehicle support 2B. When the laterally moving vehicle support 2B arrives at a position directly below the vertically moving vehicle support 1C, the laterally moving vehicle support 2A also arrives immediately below the vertically moving vehicle support 1B.

The two vertically moving vehicle supports 2A and 2B are located immediately below the ascending and descending vehicle supports 1B and 1C, and the state immediately below the ascending and descending vehicle support 1A is empty. 1B to lower the vehicle support base 1
In order to switch just below B to an empty state, it is sufficient that only the laterally moving vehicle support 2A can be moved to a position directly below the vertically moving vehicle support 1A. Since the vehicle support 50 is not provided, first, the laterally moving vehicle support 2B is laterally moved by the self-propelled drive means 50 to a position directly below the central ascending and descending vehicle support 1B. At this time, the trolley 40B suspending the laterally moving vehicle support 2B directly pushes the trolley 40A suspending the laterally moving vehicle support 2A, so that the laterally moving vehicle support 2A is pushed by the laterally moving vehicle support 2B. As a result, the vehicle moves laterally to a position directly below the ascending and descending vehicle support 1A. Thereafter, in a state where the pusher 66 of the traction means 54 is at the initial position where the pusher 66 of the traction means 54 does not engage with the pressed plate 68 of the laterally moving vehicle support 2A (the carriage 40A), only the laterally moving vehicle support 2B is again moved. The driving means 50 for self-propulsion must be moved sideways to a position directly below the lifting vehicle support 1C.

As described above, it is possible to switch the space immediately below any one of the lift vehicle supports 1A to 1C at the upper vehicle support level U, which is to be taken in and out, into an empty state. Thereafter, the upper vehicle support level U
Is lowered to the lower vehicle support level D. When any of the lift vehicle supports 1A to 1C is lowered, the motor 4 of the lift drive means 3 is turned off. Operate and drive tooth wheels 8A, 8B
Is driven to rotate in the direction in which the hanging ropes (chains) 6A and 6B are extended. As a result, each of the lift vehicle supports 1A to 1C
Ropes 6A and 6B for suspending the
A, 8B side, each elevator vehicle support 1A-1
C starts to descend due to gravity, but the laterally moving vehicle support 2A,
Two of the vertically movable vehicle supports 1A to 1C located right above 2B immediately suspend the respective laterally movable vehicle supports 2A and 2B immediately below the lower contact member 23 (see FIG. 6). Vehicle support base receiving frame portion 46 of lowered carriages 40A and 40B
(Refer to FIG. 5).
Two of the vehicles 1C are received by the lower laterally movable vehicle supports 2A and 2B (bogies 40A and 40B) and cannot descend from the upper vehicle support level U.

On the other hand, an ascending / descending vehicle support for a vehicle which cannot be received by the laterally movable vehicle supports 2A and 2B (an ascending / descending vehicle support 1C in a state shown by a solid line in FIG. 1 and an ascending / descending vehicle support 1B in FIG. 2) For example, the elevating vehicle support 1C is
As the hanging ropes 6A and 6B are extended, they descend, and FIG.
As shown in the imaginary line of FIG. 7 and FIG.
It is possible to descend to the lower vehicle support level D of the same level as 2B. The ascending and descending vehicle support base 1C lowered to the lower vehicle support level D is supported by the floor surface S when the lower contact member 23 contacts the floor surface S.

Therefore, since the hanging ropes 6A and 6B are relaxed by the subsequent extension of the hanging ropes 6A and 6B, as shown in FIG. 7, the floating guide wheel 16 has gravity (springs may be used together). As a result, the swing arm 18 separates from the upper limit stopper 19, and the limit switch 20 detects this state. Also, the driving tooth wheel 8A,
The lifting tooth wheels 12A, 12B and the lifting shaft 1 are formed by the hanging portions 6b of the hanging ropes 6A, 6B pulled up by the lifting wires 8B.
1 is guided by the ascending and descending guide rails 9A and 9B and moves upward, so that a detection signal of a detector for detecting that the ascending and descending tooth wheels 12A and 12B have reached the ascending limit position, a signal of the limit switch 20, and the like are used. Then, the motor 4 may be automatically stopped.

As described above, the lifting vehicle support 1A-
By lowering one of the lifting and lowering vehicle supports of the vehicle loading / unloading operation in 1C to the lower vehicle support level D, the vehicle can be moved in and out of the lifting and lowering vehicle support.

However, the suspension cables 6A and 6B are
Elevating vehicle support bases 1A to 1 where parts are hung up and down
C moves up and down without fear of tilting in the front-rear direction as long as the unwinding speeds of both the hanging ropes 6A and 6B are the same. The two interlocking cables 32 and 33 of the tilting prevention means 30 shown in FIGS.
A to 1C (extended frame 31) rear end left and right side portions 31
Since the ascending and descending movements of the a and 31b are forcibly synchronized, the ascending and descending vehicle supports 1A to 1C ascend and descend without fear of tilting in the left-right direction. That is, the elevating vehicle support 1A-1
C moves up and down in parallel while maintaining the horizontal posture.

The elevating and lowering vehicle supports 1A to 1C, which have completed the taking in and out of the vehicle, are not immediately raised to the upper vehicle supporting level U, but are moved to the laterally moving vehicle supporting base 2 for taking in and out of the next vehicle.
Until the situation where A and 2B have to be moved sideways,
It is desirable to keep waiting at the lower vehicle support level D as it is. The reason is that, just below, the laterally moving vehicle supports 2A, 2B
Are supported by the laterally moving vehicle supports 2A and 2B as described above, so that there is no danger of falling, but the upper vehicle support level U And the lower side supports 2A, 2
This is because one of the ascending and descending vehicle supports 1A to 1C in which B is not present may fall in the event of an accident in which the hanging ropes 6A and 6B are broken.
