Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a 0-44 type vehicle for loading and unloading vehicles using a vehicle loading fork device mounted on a stacker crane.
41 Regarding the turn + position of a car to change the direction of the automatic vehicle in a car lift) Noro.

Conventional technology + I:i Multi-story parking lot is the right f IJI publication of land in the city,
Various types of Shino have been developed and put into practical use in consideration of the cost. For example, from upstairs to downstairs C1
Installing a path for cars to dry on their own blades requires a relatively large site, but construction costs are low, so it is often used in small and medium-sized cities, whereas elevators and stacker cranes are used to dry cars. Although the construction cost of raising and lowering is relatively high, it uses a narrow site and can be used effectively, so it is often adopted in large cities, and is often used in small and medium-sized cities.
b. It is adopted when only a small amount of land can be acquired.

On the other hand, in the case of a car going up a passageway or an elevator, the driver must remain in the car and go to the desired floor, or get off from a predetermined floor.
In order to prevent such inconvenience, the parking lot has recently been closed down to a stacker crane. There is.

A multi-story parking lot using a stacker crane is one in which the stacker crane moves along storage racks that can stack multiple car storage spaces in multiple tiers.The stacker crane has a lifting deck and a It is equipped with a car loading fork device consisting of a lever that extends and retracts from the deck, and the car that enters the lobby is scooped up by the car loading fork device and transferred to the stacker crane. By moving the car in the direction l\ and moving the car loading device upward l\, the car is transported to the desired car storage space and covered, and at the time of unloading, the car is moved in the opposite direction. It is now possible to return to the lobby (for example,
9-269513).

In this type of multi-story parking lot, when entering and exiting the parking lot, there is no need to operate the car after the lobby, so the driver can get on and off the car in the lobby, and the automatic front
It is not necessary to go to the parking space at all, but since the direction of the car does not change during the round trip from the lobby to the car storage space, it is necessary to change the direction of the car in the lobby toward the entrance. , there is a problem that it is inconvenient to be forced to drive in reverse for a long distance.

Therefore, conventionally, as a means of changing the direction of a car,
In the lobby, a turntable was installed adjacent to the platform for transferring cars to the car loading fork device.
In this case, it was necessary to move the car from the platform to the turntable and back, and in order to avoid contact between the outer wall and the rotating car, it was necessary to make the lobby wider than necessary. Therefore, there was a problem that it was not desirable in terms of effective land use.

Purpose of the Invention Therefore, the purpose of the present invention is to avoid forcing the driver to drive in reverse by mounting an automatic direction change mechanism on the stacker crane in view of the actual situation of the prior art 1. However, the rotation range during automatic rotation covers the entire lobby! To provide a turning device for automobiles in a new multi-story parking lot, which minimizes the area of the lobby by extending the area without waste.

Composition of the invention The structure of this invention is to achieve this object.

A rotatable deck board is attached to the telescopic tip of the car loading fork device mounted on the stacker crane in a multi-story parking lot (ii6), and by rotating the deck board, the direction of the car can be changed while it is loaded on the stacker crane. In particular, there was no sound quality that would require space for a turntable separate from the platform, and,
The gist is that a part of the rotating range of the car can be shared with the platform space, so that the area of the lobby is not wasted.

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

When accommodating the car C in the above-mentioned multi-storey parking lot, in the lobby 12, the platform plate 19a of the platform 19 is placed on the platform board 19b so that the tires T, T... Then, the automatic medium C that entered from the doorway 14 ran onto the glazed teeth of the platform board 19a and crashed.Meanwhile, the stacker crane 20 loaded the car and the fork. Lower it to the bottom and open it (

Now, since the car C is loaded directly above the elevating deck 21, there is no need to move the stacker crane 20 or raise the elevating deck 21, and move the car C to the desired car storage space 16. I can direct you. When the car C arrives in front of the target car storage space 16, by extending the fork 22, the deck holder 23 is held out onto the II plate 17, and then raised and lowered, so that the deck 21 is gradually lifted.

By moving the car+fi mounted fork neck F, again connect the mouth and -12 to the platform 19.
The vehicle is returned to the position facing one direction, and the next vehicle C is transported and stored in the first vehicle storage space 16 by the same operation.

When the car C returns from the car storage space 16 to the lobby 12, the stacker crane 20 loads the car) A-
1. Direct the vehicle storage device 1: to the vehicle storage space 16.
(After inserting the deck boat 23 under the shelf board 17,
By raising this and passing the deck boat 23 from the bottom to the top of the shelf board 7, the tires T, 1 of the car C are placed on the comb teeth 24G, 24G... of the deck boat 23.
-... (51:J), then retract the fork 22, pull the car C together with the deck board 23 onto the lifting deck 21, and then move the stacker crane 20 toward the lobby 12.

When the stacker crane 20 loads the cars C to be left and reaches the position facing the platform 19 of the lobby 12, it extends the fork 22 and rotates the deck board 23 at the same time.

In order to avoid rotation of the deck board 23, when the -E-taper 30 is energized, the pinion 28b is driven via the belt or chain 32 and the reduction gear 31. is the turning wheel 2
It travels and revolves inside 7 and! Therefore, the deck board 23 as a whole rotates with respect to the support plate 25 by λ·1 and, in turn, with respect to the fork 22, together with the base plate 24a. Here, the balls 29, 29, . :I support it.

Now, if you turn the front side of the automatic HC to the 6th side of 2'-12 (arrow A7jlr++ in Figure 2), in front of the automatic medium C on Tey 4 Small To 23 *; 1: is, C, which moves in the direction away from the stacker crane 20, is set so that the front end crosses in front of the outer wall 13 surrounding the lobby '12 [J, the outer wall 13 is On the other hand, the rear ends 1 and 11 of the vehicle C rotate in the direction approaching the stacker crane 20.
During the 0 degree rotation, the center of rotation O moves away from the stacker crane 20 (arrow B in the figure), so the rotation center O moves away from the stacker crane 20 (arrow B in the figure), so
There is no danger of contact with the storage rack 10a located on the opposite side of the lobby 12. On the design h1 of the multi-story parking lot, we assume car C with the maximum length,
When the vehicle C is parallel to the fork 22 on the deck board 23, the distance 16 is located between the vehicle C and the safety road 1.
An outer wall 13 is provided on the outer wall 9, and the position of this outer wall 13 is
- When the deck board 23 is rotated with the lever 22 fully extended, the position where the car C will come into contact with it is good, so the lobby 12 is set very narrow;
Wear. However, the rotation range of car C is limited to the space for Blattbohm 19, Jj, and stacker crane 20.
Since it extends to a part of the passageway 11, etc., the lobby 12
The required area can be reduced.

As described above, if the deck hoard 23t is rotated 180 degrees, the direction of the automobile C loaded on the deck hoard 23 can be changed. At this time, deck board 2
It is better to make the mechanical center of No. 3 and the rotation center O coincide with each other. It is best to keep it biased toward the front when the first car enters.

This is because, in many cases, the dimensions of the vehicle body of the automobile C are larger from the center of the front and rear wheels to the rear than the front dimension.

Also, when the fork 22 is extended halfway (1/2 degree), -F! , it would be inconvenient to stop the extension and allow the deck board 23 to rotate during this stop. in this case,
Although the extension of the fork 22 and the rotation of the deck board 23 do not require a single step, safety is high, but the previous embodiment is superior in terms of time savings. Further, even if the deck board 23 is configured to rotate when the fork 22 is fully extended, this does not contradict the spirit of the invention. Even in this case, the area of the u1 go 12 can be smaller than in the conventional example in which an independent turn table is provided in the lobby 12.

Once the direction change of car C is completed, the
By lowering the platform plate 19a and passing it under the platform plate 19a, the car C is transferred onto the comb teeth, the deck hoard 23 is pulled onto the elevating deck 21, and then, by raising the elevating plate 19b, the vehicle C is moved to the platform. Move the tires T, T, etc. on the plate 19a to make it look like this. , and the driver gets on the car C and moves it forward, and the platform board 1
There is no way to go straight to entrance 14 from 9a.

<J: Jj, below [2] The operation control of each part explained above, for example, the movement of the stacker crane 20, the vertical movement of the lifting deck 21, the extension and contraction of the fork 22, the rotation of the deck hoard 23, the vertical movement of the lifting plate 19b, etc. are not shown in the figure. This is done based on electrical control by a non-contact control device.

As described in detail, according to the present invention, a rotatable deck board is provided in a telescopic vehicle loading device of a stacker crane, and by rotating the differential board, the stacker crane can be operated. By making it possible to change the direction of cars loaded on top, the lobby will be equipped with an independent turntable like the one traditionally used.
In addition, the rotating range of the car crosses the path of the stacker crane and the space of the lobby platform, making it possible to reduce the area required for the lobby to the minimum necessary. It has an effect of 10%. In addition, since the deck hoard can be rotated with the car loading and unloading device close to the lobby, a special space for the rotation must be provided on the opposite side of the lobby across the stacker crane. Instead, storage racks can be provided, and therefore, the land area can be used more effectively.

In addition, after the vehicle is transferred from the stacker crane to the truck platform, a turntable is not required, reducing the number of negative IDs required by the driver and reducing the amount of time it takes to take the vehicle out of the warehouse. It must have a practical effect.
