DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention provides a method for safely storing a vehicle in a predetermined position.
The present invention relates to a comb device for transferring vehicles in a multilevel parking system used for safely loading and unloading vehicles.

Prior Art A multi-story parking system in the form of a multi-story warehouse that combines a storage rack and a stacker crane has been put into practical use. This product is equipped with a movable stacker crane equipped with a telescopic fork device for loading cars that can be raised and lowered, and a large number of shelf-type vehicle storage spaces are installed on one or both sides of the stacker crane's running path. Vehicles are transported into and out of a predetermined vehicle storage space by the movement of a stacker crane and the lifting/lowering and expansion/contraction of a fork device.

In such multilevel parking systems, a comb device for transferring vehicles may be used. For example, each vehicle storage space is formed with a pair of comb teeth that face each other in accordance with the spacing between the vehicle tires, and the fork device has a fork device that can be moved up and down by meshing with the comb teeth of the vehicle storage space. Provide comb teeth. The vehicle supported by the comb teeth of the fork device is moved onto the comb teeth of the vehicle storage space by the comb teeth of the fork device meshing with the comb teeth of the vehicle storage space and moving from above to below. The vehicle on the comb teeth of the vehicle storage space can be transferred onto the comb teeth of the fork device by moving the fork device from below to above. That is, the comb teeth of the vehicle storage space and the comb teeth of the fork device can form a transfer device for alternately transferring vehicles between them.

Problems to be Solved by the Invention In this prior art, each comb tooth is formed into a simple bar shape with the same width from its base to its tip, so the vehicle tire tends to slip in the longitudinal direction of the comb teeth. The drawback was that it was extremely dangerous. In other words, the vehicle must be safely supported by the comb teeth while it is being transported by a stacker crane and stored in the vehicle storage space, but if the comb teeth are simple rod-shaped, the tires must be supported safely. The only force that prevents slipping is the static frictional force acting between the tire and the comb teeth, and this frictional force becomes extremely small when the tire is wet.

SUMMARY OF THE INVENTION In view of the drawbacks of the prior art, an object of the present invention is to change the shape of the first comb teeth and the second comb teeth that support the tires of a vehicle into a trapezoidal shape in plan view that becomes narrower toward the tip. To provide a comb device for transferring vehicles in a multi-story parking system, which can actively prevent tires from slipping in the longitudinal direction of the comb teeth and greatly improve overall safety. It's about doing.

Structure of the Invention The structure of the present invention to achieve the above object consists of a first comb tooth and a second comb tooth that mesh with each other and move vertically relative to each other to transfer a vehicle supported by one to the other. comb teeth, the first comb teeth and the second comb teeth each consist of a pair facing each other,
The gist is to form a trapezoidal shape in plan view that becomes narrower toward the tip.

Effect: According to the structure of the invention, each comb tooth is formed into a trapezoidal shape in plan view, so that the tire supported by the comb tooth is likely to slip in the direction from the base to the tip of the comb tooth. , in the opposite direction, its slippage is actively prevented. The space between each comb tooth is the opposite of the comb tooth itself, as it narrows from the tip of the comb tooth to the base.
This is because the tread of a tire that has fallen inward is pinched by the comb teeth on both sides, and cannot slide more than a certain distance in the direction where the tread becomes narrower. The anti-slip effect becomes more pronounced as the amount of tire deformation increases, and is particularly effective for low-pressure tubeless tires, which are rapidly becoming popular as tires for passenger cars.

Each comb tooth is made up of a pair facing each other in order to support the tires on both the left and right sides of the vehicle, so if one tire can be actively prevented from slipping in this way, the other tire will also slip. Therefore, the vehicle can be safely supported on the upper surface of the comb teeth.

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

A comb tooth device for vehicle transfer in a multi-story parking device includes first comb teeth 13a, 13a... having a trapezoidal shape in plan view.
and second comb teeth 23a, 23... (FIG. 4).

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

The storage rack 10 is a structure supported by pillars 12, 12, etc., and a pair of opposing shelf boards 13, 13 are protruded from the lower part of each vehicle storage space 11 (see Fig. 2). , Figure 3). Shelf board 13, 13
The spacing between the tires Ct of the vehicle C to be accommodated is selected in consideration of the left and right spacing between the tires Ct of the vehicle C to be accommodated.
... are arranged in rows at equal pitches (Figures 2 to 4). The shape of each first comb tooth 13a is a trapezoidal shape in plan view that becomes narrower from the base to the tip (Fig. 4), and its dimensions and strength are as follows.
It is assumed that the setting is sufficient to stably support the contact surface Cg of the tire Ct of the vehicle C.

The stacker crane 20 is guided by rails 22, 22 at both ends of the column 21, and is mounted on the storage rack 10.
(Fig. 1). Pillar 21
It can be raised and lowered in the vertical direction (direction of arrow A in the figure), and horizontally (direction of arrow B in the figure).
A fork device 23 for loading an automobile that is extendable and retractable is mounted on the vehicle. The fork device 23 includes a driving rack 24a and a pinion 2 built into the fork device 23.

The stacker crane 20 is equipped with a control device 25 (Fig. 1), and the stacker crane 20 has the following functions:
In addition to being able to position and stop at any position along the storage rack 10, the vertical position and extension/contraction length of the fork device 23 can be controlled as desired.

Now, assume that the vehicle C is stored in an arbitrary vehicle storage space 11.

First, the fork device 23 is retracted, the stacker crane 20 is moved to a predetermined loading position (not shown), and the vehicle C on the standby platform is moved onto the fork device 23, which is stopped at the same height as the standby platform (not shown). Load the vehicle and lock the handbrake.

Subsequently, the stacker crane 20 is moved, the fork device 23 is raised, extended into a predetermined vehicle accommodation space 11 (FIG. 1), and stopped at a predetermined position (FIG. 2). At this time, the fork device 23 operates the shelf board 13 of the vehicle accommodation space 11,
The first comb teeth 13 are placed at a height slightly above the upper surface of the first comb teeth 13 (FIGS. 3 and 5A).
The second comb teeth 23a, 23 are located between a, 13a...
It is assumed that the stacker crane 20 and the fork device 23 are accurately positioned so that a... is located.

Next, when the fork device 23 is lowered (FIG. 5B), the second comb teeth 23a, 23a... pass between the first comb teeth 13a, 13a... (FIG. 5C),
At this time, the tires Ct of the vehicle C that were on the second comb teeth 23a, 23a...
3a... remains on top. Therefore, if the fork device 23 is further lowered, the entire fork device 23 will eventually come out under the shelves 13, 13, and the transfer of the vehicle C can be completed (C in the same figure). The stacker crane 20 may then retract the fork device 23 and proceed to the next storage operation of the vehicle C.

When carrying out the vehicle C stored in the vehicle storage space 11, it is sufficient to carry out the procedure in the reverse order of the carrying-in procedure, and the fork device 23 extended below the shelf boards 13, 13 is moved upward. Shelf board 1

figure). It is possible to more reliably prevent the occurrence of a major accident in which the tires Ct slip and the vehicle C falls.

First comb teeth 13a, 13a... and second comb teeth 23
a, 23a... can have their upper surfaces depressed at least at positions corresponding to the contact surface Cg of the tire Ct (FIG. 8). Since the vehicle C can be prevented from moving back and forth inadvertently, the overall safety can be further improved.

In the previous embodiment, the direction of the vehicle C in the vehicle accommodation space 11 is determined by the direction of the stacker crane 20.
Although it is perpendicular to the traveling direction of the stacker crane 20, it may alternatively be parallel to the traveling direction of the stacker crane 20. Since the depth dimension of the storage rack 10 can be reduced, it is advantageous when constructing on land with a narrow frontage.

In addition, the storage rack 10 is a structure in which an arbitrary number of vehicle storage spaces 11, 11... are stacked in multiple stages.
An arbitrary number of stacker cranes 20 can be arranged in parallel in the travel direction, and furthermore, the vehicle accommodation spaces 11, 11, . . .
They can be arranged facing each other not only on one side of 0 but also on both sides.

Effects of the Invention As explained above, according to the present invention, the first
The comb teeth and the second comb teeth have trapezoidal shapes in plan view, so that when the first comb teeth and the second comb teeth cause a vehicle to be injured or killed, Since the tire tread falls between the comb teeth, which narrow from the tips of the comb teeth to the base, it is possible to actively prevent the tire from slipping in the direction of the base of the comb teeth, and Since the left and right tires of the vehicle are simultaneously supported by a pair of opposing comb teeth, the vehicle on the first comb teeth and the second comb teeth as a whole slides in the longitudinal direction of the comb teeth. It has the excellent effect of being able to achieve extremely high safety without causing any problems. In addition, each comb tooth does not have a special anti-slip finish on its upper surface, but simply has a trapezoidal overall shape in plan view, so even when manufactured in large quantities, the manufacturing cost is low. It also has the practical effect of not becoming excessive.
