Abstract

PURPOSE:To enter or deliver a vehicle into or out of a rack in a short time without using a pallet. CONSTITUTION:Multiple cantilever support bars 10 are provided on the right and left shelf members of each rack 2, and arm bars 9 crossing the support bars 10 with no interference when a fork-lift 3 is lifted or lowered in the protruded state are provided on the fork-lift 3 of a stacker crane. A vehicle can be entered or delivered into or out of the rack 2 without using a pallet, thus the efficient access can be realized in a short time as compared with the conventional system.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical multilevel parking lot using a stacker crane that does not use a dedicated pallet.

[0002]

2. Description of the Related Art Conventionally, there is a method shown in FIG. 6 (Japanese Patent Laid-Open No. 61-151374) for increasing the number of vehicles accommodated in a parking lot. In this system, the loading and unloading of the automobile A into and from the rack 2 is performed by the stacker crane 1 traveling in the longitudinal direction of the rack 2. In the case of warehousing, first, the vehicle A is driven up to the top of the pallet 14 which is set in advance in the warehousing position, and the driver gets off the vehicle A with the brake applied. Next, after the stacker crane 1 travels to the loading / unloading position, the slidable fork 3 is slid below the pallet 14 on which the vehicle A is mounted, the fork 3 is lifted and the pallet 14 is lifted by the fork 3, and then the stacker is stacked. Pull the fork 3 into the crane 1. For loading into the designated rack 2, the stacker crane 1 travels to the position of the rack 2 and is stopped on the rack 2 to a position slightly higher than the mounting level, and then the fork 3 is slid to the rack 2 and lowered. The pallet 14
Is placed on the fence 4 of the rack 2, the fork 3 is further lowered, and then stopped, and the fork 3 is returned into the stacker crane 1 to complete a series of operations. When unloading the car A of the rack 2, the procedure is the reverse of the above warehousing.

[0003]

However, in the conventional method, since the vehicle needs to be temporarily stored on the dedicated pallet, when the warehousing or unloading occurs continuously, for example, at the warehousing, In the stacker crane, first, it is necessary to go to the stacker crane to pick up the pallet stored in the rack where the car is not stored and to move it to the loading / unloading position, descend, and set the pallet. is there. Next, there is a drawback in that it takes a long time to load and unload one vehicle because the stacker crane starts loading after driving the vehicle onto the pallet. Further, there is a problem in terms of cost that pallets for the number of cars to be stored are required.

[0004]

A plurality of cantilever type support bars are provided on the left and right shelf members of each rack, and the forks slide into the rack and interfere with the support bars when the rack is moved up and down. By having an arm bar on the fork that can cross without a load, the vehicle can be loaded into and unloaded from the rack without using a pallet.

[0005]

In the loading / unloading position, there is a support bar provided on the ground which fits the tire positions of the front and rear wheels of the vehicle, and the vehicle is driven up to the support bar and stopped. The fork of the stacker crane is slid below the supporting bar and then lifted to directly scoop the tire portion of the automobile by the arm bar attached to the fork, which alternately intersects with the supporting bar, and takes it into the stacker crane. It becomes possible. In the case of mounting on a support bar provided on a shelf material in the rack, it can be performed by an operation reverse to the above scooping.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a multilevel parking lot according to an embodiment of the present invention, and FIG.
1 is a plan view of FIG. 1, FIG. 3 is a front view of a stacker crane,
FIG. 4 shows a side view of FIG. 3, and FIG. 5 shows an assembling view of comb-shaped pedestals in a rack. In FIG. 1, a plurality of rows of racks 2 are arranged on both sides of the stacker crane 1 in the traveling direction of the stacker crane 1 to form a multilevel parking lot. The stacker crane 1 is lifted and lowered by a lift drive device 7 installed on a base frame 6 along a plurality of guide posts 5 via a wire rope 12 and the like, and a lift frame 8
Formed on the rack is a foam 3 that can slide into the rack 2.
In FIG. 2, the fork 3 is provided with a plurality of arm bars 9 in both directions with respect to the sliding direction in accordance with the positions of the tires 11 of the front and rear wheels of the automobile A. On the other hand, when the fork 3 slides in the rack 2 in each rack 2 and moves up and down at the stopped position, the cantilever type alternately intersects with the arm bars 9 attached to both sides of the fork 3. A plurality of support bars 10 are provided. A traveling drive device (not shown) is provided on the base frame 6 of the stacker crane 1 to travel on a rail 13 laid in the longitudinal direction of the rack 2. The procedure for leaving the automobile A stored in the rack 2 will be described below. First, if the rack 2 position to be unloaded is designated, the stacker crane 1 moves up and down to the designated rack 2 position and travels.
The ascending / descending stop position is a position where the upper surface of the fork 3 is slightly below the lower end position of the support bar on the rack side, and a position where a gap is secured when the fork 3 slides is stopped. Next, after sliding the fork 3 into the rack 2, the lifting frame 8 is lifted by the lifting drive device 7. Since the arm bars 9 attached to both sides of the fork 3 and the support bars provided on the shelf material 4 of the rack 2 are in a positional relationship of alternately intersecting each other, FIG.
As shown in FIG. 5, when the forks 3 are lifted, they can intersect without interfering with each other. The vehicle A, which is directly stored in the support bar 10 of the rack 2 before the fork 3 rises, has the tire 11 portion supported by the arm bar 9 on the fork side as the fork 3 rises and the support bar 10 on the rack 2 side. Is cut off. After the ascent of the fork 3 is stopped, the fork 3 is slid into the stacker crane 1 and retracted, and the stacker crane 1 travels and descends to the loading / unloading position. A supporting bar 10 having the same shape as the inside of the rack 2 is provided even at the loading / unloading position arranged on the ground, and the fork 3 stopped at a position higher than the supporting bar 10 is slid above the supporting bar and then lowered. The arm bar 9 on the fork 3 side and the support bar 10 at the loading / unloading position.
Alternately intersect with each other without interference, and the car A is transferred to the support bar 10 installed on the ground. At the same time as the driver gets in the automobile A and exits the multi-storey parking lot, the fork A is pulled in, the stacker crane 1 is moved to the position of the rack 2 where the next issue command is issued, and the issue operation can be started. Carrying in the car A can be performed by performing the operation opposite to the above-mentioned warehousing.

[0007]

The vehicle can be loaded and unloaded from the support bar in a short time because it can be taken in by a stacker crane and stored in a rack without using a dedicated pallet.
