Abstract

PURPOSE: To provide a simplified structure by storing automobiles on motor- equipped traversing pallets on trays except the uppermost and lowermost trays, and causing the trays hung by means of chains and hanging members to be raised and lowered by one drive portion per line. CONSTITUTION: When an automobile is to be taken out of A1 , for example, a leveling device 5 is operated to establish the levels of lines A, B, C. When the traversing pallets 3 of A1 , A2 , A3 are made to self-travel to B2 , B3 , B4 , a home position sensor detects the pallets, and the pallets are stopped in predetermined positions. In this case, below A1 is only a tray 1 used for holding the pallets of A2 , A3 and held by a tray hanging member 10. When a lift-brake- equipped geared motor 4 is operated in the downward direction, the tray 1 of A3 arrives at the foundation, and the tray 1 of A2 is stacked thereon. When the uppermost tray 2 of A1 is further stacked thereon, a sensor detects it, stopping the motor 4 and permitting the automobile in A1 to be taken out. Thus automobiles are raised and lowered by one drive, whereby the system and structure can be simplified.

Description

Each row of A, B, C is equipped with one gear motor with 4 lifting brakes, 1 main sprocket and shaft, 8 chain, 9 small sprocket for suspension, 10 tray suspension members, 1, 2 Hanging tray. 3 traverse pallets are placed on the 11 rails of this tray, and the cams of the 5 leveling devices installed on the front and rear surfaces are driven by the motor to push up the trays in rows A, B and C by 5 m / m to level out. When you do, the lateral movement condition is completed. At this time, as shown in FIG. 2, the 6 stoppers are lowered downward and unlocked only under the condition that the trays are adjacent to each other. The tray is equipped with guide rollers at the four corners, and the stanchions are used as guides. There is no need to move laterally at the top and bottom when entering and leaving the car, and the car is directly on the tray. The bottom pallet moves laterally directly on the rail installed on the foundation. B
_There is no pallet in ₂ , B ₃ , and B _{4, and} it is always empty as a receiving space for the laterally moving pallet. The presence or absence of a car is constantly confirmed by 12 photocells. The operation when the A ₁ is unloaded will be described. The 6 stoppers are in the released state, and the 5 leveling device operates to complete the leveling of the rows A, B, and C. Next, the A ₂ , A ₃ , and A ₄ pallets are self-propelled to B ₂ , B ₃ , and B ₄ and stopped by the localization sensor detection. Below A ₁ , there are only A ₂ and A ₃ trays held by 10 tray suspension members. 4 elevator geared motor with a brake is actuated in the downward direction, A ₃ tray arrives at the basic, continued A ₂ overlies the A _3. Furthermore, when the A ₁ tray is overlaid on it, the geared motor with 4 lift brakes is stopped by the sensor detection,
_{The first} car is ready to leave. The receipt of A _{1 and} the exit of C ₂ are performed by the same operation. As shown in FIG. 4, parking efficiency can be increased by allowing the pallet to move in the vertical direction as well as to use the land with a narrow entrance and a deep space and the space for entering and exiting the carriageway.
