FIG. 9 shows another embodiment of the movable deck, in which the movable deck 71.7 is in the traveling path forming position.
This is an example in which the step S between 1 and the fixed deck 72 is reduced.

That is, in the case of the previous embodiment, it was not possible to make the fixed deck 36 higher in order to avoid interference with the wheels 31 when the movable deck 25 moves laterally. On the other hand, in the example shown in FIG. 9, the rail surface of the fixed deck 72 in the rail member 73 is set as a horizontal rail surface 73a, and the fixed deck 72 is provided at a high position without interfering with the wheels 75 of the movable deck 71. to be able to
The part on the loading/unloading position side following the horizontal rail surface 73a is a sloped rail surface 73b that slopes downward toward the loading/unloading position side, and the slope of this sloped rail surface 73b is made larger than the rail slope of the previous embodiment. This ensures the height difference due to the lateral movement of the movable deck 71.

The horizontal rail surface 73a and the slope rail surface 73b of the rail member 73 are also located on the lower surface of the movable deck 71 at the loading/unloading position side.
A horizontal guide surface 71a and a slope guide surface 7 respectively corresponding to
1b. 76 is a roller that guides the horizontal guide surface 71a and the slope guide surface 71b, and 77 is a cylinder device for lateral movement.

In this example, as mentioned above, the gradient becomes larger, and the driving force required of the cylinder device 77 increases accordingly, but this does not pose a problem because there are no vehicles or people on the moving deck 71 when it moves. Must not be.

FIGS. 10 and 11 show other embodiments of the lifting means of the swing device.

That is, in the previous embodiment, the vehicle is raised and lowered together with the pallet 12 by the lifting means 441; however, in this example, the load of the vehicle and the pallet 12 is not directly applied to the driving portion of the lifting means 81. It is something that can be done.

Specifically, first, the lifting support stand 82 itself is guided by guide columns 83a and 83b similar to those in the previous embodiment, and can be lifted and lowered in a horizontal state by a guide chain 85 suspended from guide sprockets 84a and 84b. ing.

Regarding the elevating means 81, the guide pillar 83b on the entrance/exit side;
The rotating shaft 86 is passed horizontally between the lower ends of each of the parts 83b,
Crank arms 87, 87 are coupled to both ends of this rotating shaft 86, and the crank arms 87, 87 and the lifting support
2 are connected by a rod 88°88. A lifting motor 89 (guard motor) is provided at the bottom of the pit 28, and this lifting motor 89 and the rotating shaft 8
A driving sprocket 91 and a driven sprocket 9 between
A transmission means consisting of a transmission chain 93 and a transmission chain 93 is provided.

Note that illustration of the swivel table and swivel means is omitted.

In use, the crank arm 87 is rotated and stopped at its top dead center, that is, the lifting support base 82 is placed in the uppermost position, and in this state, the lifting platform (elevator) of the hoistway that connects the storage/exit section and the parking section is ) is lowered (immediately before stopping and at low speed), and the vehicle is placed on the swivel table above the lifting support table 82 together with the pallet. Then, by turning the swivel table in this state, the direction of the vehicle is changed, and then the hoistway platform is raised to pick up the vehicle together with the pallet, and the elevating support table 52 is lowered.

Therefore, the elevating means 81 only raises and lowers the swivel platform and the revolving means, and the vehicle itself can be raised and lowered using an elevator, so the load of the vehicle does not directly act on the elevating motor 89 and the transmission means. , these can be made into low-load and simple ones.

Of course, the elevating means 81 can also be used by itself to raise and lower the vehicle together with the pallet, as in the previous embodiment. The error in the stopping position at the end can be extremely reduced, and the robot can start moving up and down at a slow speed, gradually speed up, reach the maximum speed in the middle, and then gradually slow down and end the move at a slow speed. Since the lifting speed changes sinusoidally, the effect is that the operation can be made extremely smooth.

In the above embodiment, the moving deck is moved laterally by a cylinder device, but other means for moving the moving deck laterally, such as a chain feeding mechanism, may be used.

In addition, in the above embodiment, the two movable decks are aligned at the loading/unloading position, but it is possible to combine the movable decks into one and move this one movable deck laterally between the loading/unloading position and its side. You can also do this.

Further, in the above embodiment, two parking devices are arranged in tandem, but it goes without saying that the present invention can also be applied to cases in which three or more parking devices are arranged in tandem.

In addition, although the parking device in the above embodiment is an elevator type parking device with a bottom entry system, it may also be an upper entry system, a middle entry system, a vertical circulation type, a horizontal circulation type, or a box type circulation type. The present invention can also be applied in the same manner as in the above embodiments.
