The occupying area can thus be effectively utilized.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention uses a left and right feeding device to transport trays arranged in two vertical stages on a steel frame installed in a parking space below the second floor or underground. The present invention also relates to a parking device in which a forklift for raising and lowering the tray is attached to a parking device unit that lowers the upper tray to the lower tray using tray rotation devices installed at both ends of the tray row, and at the same time raises the lower tray to the upper tray. More specifically, the present invention relates to a multi-layer circular parking system in which the above-mentioned parking system units are stacked vertically in a plurality of layers, and a method for operating the same.

(Conventional technology) In a circular circulation parking system as described above.

When planning a parking lot for a building, in order to reduce the volume occupied by the parking equipment and make it more compact as a whole, the floor surface of the elevator section and the floor surface of the circulation section were designed without creating a pit to accommodate the elevator compartment moving section. The one that made it to the same level was JP-A-6
This is proposed in Japanese Patent No. 4-58775.

(Problem to be Solved by the Invention) However, even if it is intended to double the number of parking devices by superimposing another parking device unit on the upper layer of the parking device unit of the circular circulation parking device of the Pi-I-less type, the lower layer When removing the tray from the parking device unit.

There is a drawback in that the tray placed on the lift frame of the forklift hits the tray in the rotating part of the upper parking unit, making it impossible to remove the lower tray.

An object of the present invention is to reduce the number of spaces or trays accommodated in the upper parking device unit by one compared to the number of spaces or trays accommodated in the lower parking device unit (3), thereby increasing the number of vehicles accommodated and making effective use of the occupied area. An object of the present invention is to provide a multi-layer circular parking system and an operating method thereof.

(Means for Solving the Problems) In order to achieve the above object, the multi-layer circular parking system of the present invention is arranged in two stages, upper and lower, on a steel frame installed in a parking space below the second floor or underground. At the same time, the installed trays are transferred by a left and right feeding device, and the upper tray is lowered to a lower layer by the 1 to 1 tray turning devices installed at both ends of the tray row.

When an upper parking device unit having the same structure as the previous one is superposed on top of a lower parking device unit in which the lower tray is raised to the upper level, and the number of trays in the lower parking device unit is N.

The number of trays in the upper parking device unit is set to N-1, the number N of lower layer trays is an even number, the number of upper layer trays is an odd number, and the tray has a foldable elevating frame on either side of both the parking device units. It is equipped with a forklift for lifting (4).

In addition, as an operating method of the multi-layer circular parking system of the present invention, the tray of the upper parking system unit is moved and circulated to form a portion without a tray or a ghost tray at the end of the lift side, so that an empty hoistway area is formed. By doing so, the tray of the lower parking device unit is taken out, the lower tray is moved half a pitch, and after the elevating frame of the forklift has passed, the upper tray is taken out.

There is a method of operating a multi-layer circular parking system according to claim (1), characterized in that during this period, a preparation operation for taking out the lower tray is performed.

(Example) In FIGS. 1 and 2, the multi-layer circular parking system is composed of 9, for example, an upper parking unit U, a lower parking unit 1 to TJ, and a forklift FL. A parking device unit U1 (lower parking device unit 1-U2), a tray 2 on which cars 1 are placed, which are arranged side by side in two upper and lower stages on a machine frame or a steel frame (not shown) as appropriate.
(2'), a driving sprocket wheel 3 (3'), a driven sprocket wheel 4 (4'), and a link chain 5 (5') suspended endlessly on these sprocket wheels. ') are respectively attached to link chains 5 (5') via attachments (not shown), and drive sprocket wheels 3
The trays are moved and circulated in the directions of the arrows by the rotation of (3'), and the upper trays are lowered to the lower tiers and the lower trays are simultaneously raised to the upper tiers at the same time by mechanical turning devices to be disposed at both ends of both tray rows. It is configured as follows.

Each of the parking device units U and U constructed in this way
Tray 2 (2'
) is installed for raising and lowering a forklift FL (for example, see the above-mentioned Japanese Patent Application Laid-open No. 64-58775). It consists of a pair of drive roller chains 8, a drive sprocket wheel 9 and a rear moving sprocket wheel 10, which are attached to the lower and upper parts of the lift column on which these chains are mounted, and the drive roller chain A counterweight 11 is attached to the outside of the lift.

The elevating frame 6 is lowered or raised by the rotation of the wheel 9 to the quick-acting sprocket 1 driven by an elevating device (not shown) as appropriate.

Note that the number of trays 2 in the upper parking device units 1 to U1 is one less than the number in the lower parking device unit U2, that is, the number of trays in the lower parking device unit U2 is N (16 in the illustration). When I did.

The number of trays in the upper parking device unit U1 is N-1 (15 in the figure).

As a result, a portion without a tray (ghost tray) is formed at the end of the lift I side of the upper parking device unit, resulting in an empty elevator path area 12, so that the elevator frame 6 of the forklift FL can freely pass through. This allows the tray 2' of the lower parking device unit to be taken out.

On the other hand, the number of 1 helay 2' (7) of the lower parking device unit U2 is an even number N, and the number of 1 helay 2' (7) of the upper parking device unit U1 is
~The number of relays 2 is an odd number of N-1 units.

As shown in FIG. 3, by moving the stopping position of the lower tray 2' by half a pitch, the lifting frame 6 of the forklift FL in the folded state can be raised, and after passing through the tray rotation area, During tray removal of the tier parking unit, the lower tier parking unit may also be primed.

(Function) The tray 2' of the lower parking device unit huz is moved and circulated, and after being placed on the lifting frame 6 of the forklift FL located at the position indicated by the two-dot chain line shown in FIG. When the vehicle rises, the upper parking unit (
1), a ghost tray without the tray 2 or an empty hoistway area 12 is formed in the revolving section, so the elevating frame or tray rises without hitting the upper tray 2 and reaches the solid line position; The vehicle 1 is entered and exited from the warehouse through the entrance 13.

(8) Also, as shown in FIG. 3, when the forklift FL is at the lowest position, that is, with the elevating frame 6 folded, the tray 2' of the lower parking device unit U2 is moved by half a pitch, and the elevating frame After passing through the rotating part of the lower parking device unit, the lifting frame is opened and the tray 2 of the upper parking device unit U1 is taken out. ' can perform the unloading preparation operation.

(Effects of the Invention) From the above, according to the present invention, the number of trays in the upper parking device unit must be reduced by two in a simple overlapping circular circulation parking device, whereas,
By reducing the number of trays by one compared to the number of trays in the lower parking device unit, it is possible to take out the tray of the lower parking device unit, and the number of cars accommodated can be doubled.
- Since the number of trays in the first layer parking device unit is an odd number and the number of trays in the lower layer parking device unit is an even number, the preparation operation of the lower layer parking device unit 1 is possible while taking out the tray of the upper layer parking device unit. This has the effect of shortening the time it takes for cars to enter and exit the garage.
