Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a multi-story parking system, particularly a multi-story automobile parking system in the form of a multi-story warehouse, which is composed of storage racks and stacker cranes.

Prior Art The applicant previously proposed, as a means of solving the problem of securing parking lots in cities, a storage rack configured by stacking car storage spaces in multiple stages, and a stacker crane that can run and move along the storage rack. We proposed a multi-storey parking system in the form of a multi-storey warehouse.

There, a first comb tooth and a second comb tooth are formed in the car loading fork device and the car storage shelf so that the car loading fork extends into the car storage space. By moving the device up and down so that the ground plane of a car tire supported on the top surface of one comb tooth is supported on the top surface of the other comb tooth, it can be used as a car storage shelf without using pallets. This realizes mutual transfer of vehicles between the vehicle loading fork device and the vehicle loading fork device.

However, in the multilevel parking device according to this prior art, the running direction of the stacker crane,
In addition to aligning the longitudinal direction of the automobile on the stacker crane and in the automobile storage space, the direction of each comb tooth provided on the automobile loading fork device and the automobile storage shelf is perpendicular to the longitudinal direction of the automobile. The comb teeth support the tire on the contact surface of the car tire in a state perpendicular to the circumferential direction of the tire, and the ridgeline on the top surface of the comb teeth bites into the tire, so it is especially suitable for low-pressure tires. There was a problem in that when a car equipped with a tire was stored for a long time, the tire could become deformed.

Purpose of the Invention In view of the actual state of the prior art, the purpose of the present invention is to provide an improved multi-level parking system that does not cause the tires to deform even when cars equipped with low air pressure tires are accommodated for a long period of time. Our goal is to provide the following.

Structure of the Invention The structure of the present invention for achieving the above object is a multi-level warehouse type warehouse comprising a storage rack and a stacker crane equipped with a car loading fork device that can access any car storage space on the storage rack. In the multi-story parking system, the car storage shelf in the car storage space and the car loading fork device have at least first comb teeth and second comb teeth provided at a position that supports a contact surface of a car tire.
By providing the comb teeth in a direction that corresponds to the longitudinal direction of the vehicle in the vehicle storage space, each comb tooth supports the tire along the circumferential direction of the tire, and the upper surface of the comb tooth The gist of this is that since the ridgeline part of the tire does not dig into the tire, there is no risk of deformation of the tire even if the tire is supported for a long period of time.

Example Examples will be described below with reference to the drawings.

The multi-story parking device has car storage spaces 11 and 1.
It consists of a storage rack 10 in which 1... are stacked in multiple stages, and a stacker crane 20 that can move along the storage rack 10 (Fig. 1).

23c, 23... are individual comb teeth 13a, 23a
However, its position, size, and depth are such that when the relative heights of the car storage shelf 13 and the car loading fork device 23 are matched, a smooth pot-bottom-shaped depression is formed from one piece as a whole. It is designed to form a One depression formed at this time is
Each comb tooth 13a, 23a has a substantially rectangular pot bottom shape with depth gradually increasing from the periphery to the center, and has a size of approximately 600 mm in the longitudinal direction and approximately 400 mm in the width direction of the vehicle to be accommodated. The shapes and dimensions of the individual depressions 13c and 23c provided in the wafer are determined.
Further, the position is such that it can cover the range that supports the ground contact surface of the tire Ct of the car C to be accommodated.

The automobile C is positioned such that the ground plane of Ct falls into the second recesses 23c, 23c, . . . above the second comb teeth 23a, 23a, and is stopped. car C
Since the tread, wheelbase, and size of the contact surface of each tire Ct differ depending on the vehicle model, the contact surface of each tire Ct may not always coincide with the deepest part of the depression 23c, but in that case,
The weight of the vehicle C acting on the inclined surface of the recess 23c acts in a direction that causes the tire Ct to fall into the deepest part of the recess 23c.
It is possible to effectively eliminate the possibility of the user accidentally slipping down from 3a. In addition, the depressions 23c, 23c
... has the above-mentioned size, so that it is possible to load most of the domestic ordinary passenger cars so that all the wheels are located at least on the slope of the recess 23c.

Next, the car loading fork device 23 loaded with the car C is positioned slightly above the car storage shelf 13 and inserted and extended into the car storage space 11 (the top stage in FIG. 1). If the horizontal position and extension length of the automobile loading fork device 23 are determined so that the guide block 24 fits into the groove 14a of the guide 14, the first comb shelves 13a, 13a, . . . and the second comb teeth 23a, 23a... are positioned so that they mesh without interfering with each other. Therefore,

...There is no risk that the ridgeline portion of the upper surface will dig into the tire Ct. Furthermore, first comb teeth 13a, 13a...
... and the second comb teeth 23a, 23a... have protrusions 13d, 13d..., respectively, on the top surface tips thereof.
23d, 23d, . . . are formed, it is possible to effectively prevent the tire Ct of the automobile C from rolling beyond the tip of each comb tooth 13a, 23a.

Needless to say, when carrying out the car C from the car storage space 11, it is sufficient to carry out the procedure completely reverse to the above-mentioned storage procedure.
3, the car loading fork device 23 inserted and extended slightly below the car storage shelf 13 is raised.
The automobile C supported on the combs 13a, 13a, . . . is transferred onto the second comb teeth 23a, 23a, . At this time as well, the mutual fitting of the guides 14 and 24 facilitates positioning of the vehicle loading fork device 23.

In addition, as long as the first comb teeth 13a, 13a... and the second comb teeth 23a, 23a... form a group that meshes with each other and are parallel to each other, the automobile C
It is also possible to form it diagonally at a slight angle with the front-rear direction. Since it is possible to increase the number of comb teeth 13a, 23a that support the ground contact surface of the tire Ct, it is advantageous to increase its load capacity.

Effects of the Invention As explained above, according to the present invention, the first comb, which is provided on the car storage rack and the car loading fork device of the multi-story parking system in the form of a multi-story warehouse, is engaged with each other and can pass vertically. The direction of the tooth and the second comb tooth,
By arranging it in a direction that matches the front-rear direction of the car in the car storage space, there is no risk that the ridgeline on the top surface of the comb teeth will dig into the tire, making it ideal for storing cars that have been fitted with low-pressure tires for a long period of time. This has the excellent effect that there is no risk of deformation of the tire even if the tire is

In addition, the first comb teeth and the second comb teeth can be directly implanted in the car storage rack and the car loading fork device, respectively, and there is no need to interpose any structural member in between, so the mechanical structure can be easily fixed. Another structural advantage is that it can increase strength.
