Description

Description: TECHNICAL FIELD The present invention relates to a multi-layer circulation parking facility in which a plurality of circulation parking devices are vertically arranged in layers.

(Prior Art) Generally, a plurality of pallets on which a vehicle is mounted are circulated in an elliptical loop by upper and lower horizontal transition parts and arcuate transition parts at both ends connecting these horizontal transition parts. Parking devices are known. Then, the parking device is arranged in upper and lower layers, and an elevating means for elevating the pallet between the upper and lower parts of the vehicle is provided beside the parking device. There is also known a device which transfers pallets to and from the device (see Japanese Patent Laid-Open No. 51-104785).

In such a multi-layer circulation parking facility, for example, when a vehicle is received together with a pallet from a parking device in the lower layer by an elevating means and is taken out to an upper vehicle entrance / exit portion, if it is lifted as it is from the position of the arcuate transition portion, It will interfere with the pallet located in the arcuate transition of the parking device above it. Therefore, in the technique described in the above publication, the ascending / descending path of the pallet by the ascending / descending means and the arcuate transition path of the pallet by the parking device do not overlap each other, and the pallet can be moved laterally on the ascending / descending means. The pallet received by the arcuate transition portion is temporarily taken out of the arcuate transition portion, and the pallet is moved up and down at the ejection position to avoid the above interference.

(Problem to be Solved by the Invention) However, in the case of the above-mentioned conventional technique, since the ascending / descending trajectory of the pallet and the arcuate transition trajectory cannot be overlapped with each other, a wide ascending / descending space is required beside the parking space of the vehicle. There's a problem.

On the other hand, by providing a pallet-less portion in the elliptical pallet row in the parking device, the parking device is actuated when the pallet is moved up and down by the elevating means so that the pallet-less part is moved up and down. It can be considered to position it on the side to prevent the above interference. According to this, it is possible to save space by overlapping the ascending / descending trajectory of the pallet with the arcuate transition trajectory.

However, in this case, it is necessary to bring the pallet-less part of the parking device to the elevating device side at the time of operation of the elevating device, and it takes time to move the part without the pallet and the pallet from one of the parking devices. While the pallet to be taken out next is determined, the other parking device cannot forward the pallet to the lifting means side in advance, and in the end it takes time to move the car in and out. This will be the case. Further, as described above, when the parking device is provided with the pallet-less portion, the number of parkings in the parking device is reduced accordingly.

(Means for Solving the Problem) In order to solve the above problems, the present invention, when a pallet is moved up and down, the parking device on the ascending / descending path positions the intermediate portion of two adjacent pallets at the arcuate transition portion. As a result, it is possible to partially wrap the lifting and lowering trajectory of the pallet and the arcuate transition trajectory without causing interference between the pallet being raised and lowered and the pallet on the parking device. The pallet can be moved laterally on the lifting means to enable smooth delivery of
It is possible to quickly move in and out of a car without reducing the number of parked cars or expanding an elevating space.

That is, the multi-layer circulation parking equipment according to the present invention has a plurality of parking devices arranged in layers vertically to move a plurality of pallets on which a vehicle is placed so as to draw a trajectory of an oblong circular shape on a vertical plane and circulate the plurality of parking devices. And a trailing locus partially wrapped around the arcuate transition locus of the pallet at one end of each of the parking devices provided between the parking station and a vehicle entrance / exit station arranged above or below the parking station. Lifting means for raising and lowering the pallet, pallet moving means provided on the raising and lowering means for horizontally moving the pallet for delivery of the pallet between the raising and lowering means and the parking device, and parking for delivering the pallet. The delivery part of the device is moved to the lap position between the arc-shaped transition locus and the elevating and lowering locus so that the parking device moves up and down when the pallet goes up and down. So as not to interfere with the dot and middle portion between two pallets adjacent the parking device located on the lifting path in which and a parking apparatus control means for moving the said lap position.

(Operation) In the above-described multi-layer circulation parking facility, the parking device located on the ascending / descending path of the pallet when ascending / descending shifts the intermediate portion of two adjacent pallets to the wrap position of the ascending / descending trajectory of the pallet and the arcuate transition trajectory. As a result, the protrusion to the lap position is eliminated, and the interference with the ascending / descending pallet is prevented.

When moving up and down, the middle part of the pallet of any adjacent set in the parking device may be shifted to the lap position. Therefore, if there is no pallet to be taken out next, the middle part of the set closest to the lap position. By shifting, the shift time can be shortened and the pallets can be raised and lowered quickly. If there is a pallet to be taken out next, the middle part of the set including the pallet is shifted, and after the previous pallet has been lifted and lowered, the next pallet is moved to the lap position by a slight movement, that is, the lifting means. It can be brought to the delivery position with respect to, and the necessary pallet can be quickly taken out.

Further, when transferring the pallet between the lifting means and the parking device, the pallet moving means can move the pallet between the lifting trajectory and the arc-shaped transition trajectory. At least the amount of overlap with the locus enables smooth delivery.

(Effect of the invention) Therefore, according to the present invention, the pallet ascending / descending path and the arcuate transition path of the parking device are partially overlapped so that the pallet being lifted and the pallet on the parking device do not interfere with each other. Since the intermediate portions of two adjacent pallets of the apparatus are shifted to the lap position, and the pallets can be moved on the elevating means to enable smooth delivery of the pallets even with only a part of the laps. By increasing the number of parking units in one parking device as much as possible without expanding the elevating space and shifting the middle part of the pallet of the group closest to the lap position, the pallet can be shortened to reduce the shift time. Quickly raise and lower,
By shifting the middle part of the set including the pallet to be taken out next, the next pallet can be taken out quickly.
