The roller 64 of the power cylinder 63 is detached from the guide groove 9 formed on the back surface of the tray, and in this state, the other tray 2 is moved horizontally to the dead space.
When reaching S ₁ , the female connecting fitting 18 and the male connecting fitting 19 collide, so the tray retracting/extracting device 36 is activated in advance to move the tray toward you by approximately 250 l.
The tray is moved vertically by about mm, and furthermore, as the tray is moved vertically, the roller 64 of the power cylinder, which had been detached until then, fits into the guide groove 9 on the back surface of the tray. When the tray is moved to the left by l'=approximately 100 mm, the longitudinal wheels 26 of the tray are disengaged from the front fixed rail 25, and the transverse wheels 22 are placed on the auxiliary transverse rails 30.

Therefore, in FIG. 3, in order to put the car in (take out) the warehouse, the vertical feeder ₃₂ is driven to move the tray 2 in position to the dead space _S2 , and then the horizontal feeder ₄₂ is driven. When the tray 2 in the position is transferred to the elevating frame 8 of the forklift 6, a dead space S ₁ ' is formed. Next, when the tray 2 is moved to the dead space _S1 by driving the traversing device 42, the tray 2 is moved to the dead space _S1 .
When another dead space S ₁ ″ is formed next to S ₁ ′, the traversing power cylinder 63 is activated to move the tray 2 ′ by a distance l ′, and the traversing wheels 22 of the tray move on the auxiliary lateral rail 30 . At the same time as traveling a distance l', the longitudinal wheels 26 move to the front fixed rail 25.

When the tray retracting/extracting device 36 is driven in this state, the tray 2' travels a distance l on the front fixed rail 25, and the male connecting fitting 19 of the tray is connected to the female connecting fitting 18 of the tray 2 on the dead space _S1 . By meshing to form the coupler 20, a row of trays is integrally formed, and if this tray row is moved to the right by driving the traversing device ₄₁ twice, a dead space _S1 is formed. Therefore, tray movement circulation, ie, preparation operation, can be performed in a two-step manner between the pre-formed dead space _S2 and the dead space _S1 .

Next, the forklift 6 that has completed loading (unloading)
When the tray 2 on the lift frame 8 enters (takes out) the first floor underground, the level of the parking device unit 5, that is, the fixed rail 23 on the lift frame 8 and the front fixed rail 25 are at opposite end positions. Confronting the 6th
7B, by driving the tray retracting/extracting device 36, the drive sprocket 41 is rotated in the direction of the hour hand (in the direction of the arrow) as shown in FIG. , the endless chain 42 moves in the direction of the arrow, and therefore,
A traction roller 58 attached to this endless chain and fitted into a groove-shaped latch 57 provided on the back side of the tray 2 allows the tray to be moved between the fixed rail 23 on the elevating frame 8 and the front side of the tray. After traveling on the fixed rail 25 and being fixed at a predetermined position corresponding to the front tray row, further,
The tray is moved forward by a distance l by the operation of the tray pull-in/pull-out device 36, and is moved by a distance l' by the transverse feed power cylinder 63.

In addition, when entering (and exiting) a car in the parking device unit 5 on the second floor underground, the elevating frame 8
The end of the upper fixed frame 23 passes through the front fixed rail 25 of the first level underground as shown in FIGS. 6 and 7a, and is inserted into the parking apparatus unit in the manner shown in FIG. 7b. This is brought to the (exit) warehouse level, and although the above example describes a multi-layer flat circulation type parking facility, it is of course possible to achieve the same purpose with a single-layer flat circulation type parking facility. .

(Effects of the Invention) As described above, according to the present invention, a front fixed rail is provided in the front side space of a forklift, and a fixed rail is provided on the tray retracting and extracting device and the lifting frame, and the front fixed rail A tray with longitudinal wheels and transverse wheels is placed on top to increase the number of vehicles accommodated, and the tray is incorporated into a two-step tray movement circulation, i.e., preparation operation, in the parking device unit of the extraction layer, thereby reducing the loading and unloading time.
