DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage system such as a fork-type multi-story parking lot for storing automobiles.

[0002]

2. Description of the Related Art Conventionally, for example, as a multi-story parking lot, a gondola type parking lot in which a rotor having a plurality of vehicle loading tables is rotated and vehicles are sequentially loaded is known. However, in this gondola type, the rotor cannot be rotated at a high speed, and the entire apparatus becomes large-scale. Therefore, in recent years, a fork type has been widely used instead of the gondola type.

In the fork type multi-story parking lot system, a multi-story parking lot is formed by adjoining a plurality of storage towers. On each floor of the containment tower, there is formed a traveling passage on which the truck travels. The traveling passage is constituted by a pair of guide rails which engage with traveling rollers of the bogie. The cart reciprocates between the storage towers along the guide rail. Further, a plurality of parking rooms are formed on both sides of the traveling passage on each floor, and a traverse tray is arranged in each space. The traversing tray traverses between the traveling passage and the parking room. In the one storage tower, an elevating lift for transporting a vehicle to a predetermined floor of the storage tower is provided on a traveling passage.

When entering a vehicle, first, the truck is moved to a position facing a parking room where no vehicle is stored, and a transverse tray in the parking room is placed on the truck. Next, the trolley is moved to a position facing the elevating space where the elevating lift moves, and then the traversing tray on the trolley is lowered to the elevating space. In this state, when the lift on which the vehicle is mounted is moved to a predetermined floor where the traversing tray waits, the fork of the traversing tray is engaged with the fork of the lifting lift, and the vehicle on the lifting lift is transferred onto the traversing tray. . After the vehicle has been transferred onto the traversing tray, the traversing tray is placed on the carriage again. Then, the carriage is moved to a predetermined parking room, and the transverse tray on the carriage is returned to the parking room.

[0005] The vehicle is stored as described above.

[0006]

However, in the above-described fork-type multi-story parking lot system, it is necessary to move the bogie to a position facing the parking room where the vehicle is not stored every time the vehicle is parked. For this reason, there is a problem that the entry / exit operation of the vehicle is not performed smoothly.

[0007] Further, since the traveling passage is constituted by a thin guide rail, its strength is relatively low. for that reason,
The truck cannot run at high speed, and the vehicle cannot be smoothly entered and exited. As a result, the number of vehicles that can enter and leave the vehicle within a prescribed time period decreases, and as a result, the number of parking rooms decreases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a storage system capable of smoothly carrying out storage and retrieval of stored items.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, the floor is divided into a plurality of floors,

[0013] According to the invention described in claim 5, the first aspect is provided.
In the storage system according to any one of claims to 4, the gist is that the storage room is provided on both sides of the passage.

[0014]

According to the first aspect of the present invention, since the carriage has a plurality of upper and lower placement portions on which the transverse tray is placed, the transverse tray is always placed on the carriage. Can be. As a result, it is not necessary to take out the traversing tray from the storage room each time the storage object is stored.

According to the second aspect of the present invention, when the traversing tray is placed on the placing portion of the cart, the traversing tray is placed on the placing portion as the tray placing means is driven. When lowering the traversing tray from the placing section, the traversing tray is lowered from the placing section as the tray lowering means is driven.

According to the third aspect of the present invention, when the storage room and each mounting portion of the cart are opposed to each other, the mounting portion is moved up and down by the elevating means. Thereby, each placement unit and the storage room face each other, and it is possible to place the traversing tray from the storage room to the placement unit and to descend from the placement unit to the storage room.

According to the fourth aspect of the present invention, when storing a stored object in the storage room, first, the traversing tray placed on the placing portion of the cart is lowered into the lifting space by the tray lowering means. . Next, the lifting lift on which the stored object is placed is moved up and down to a predetermined floor where the traversing tray is on standby. When the elevating lift moves to a predetermined floor, the fork of the elevating lift and the fork of the traversing tray overlap, and the items stored on the elevating lift move onto the traversing tray. Then, the traversing tray on which the storage object is placed by the tray placing means is placed again on the carriage from the elevating space. When the traversing tray on which the stored items are placed is placed on the trolley, the trolley moves the nearest stored item from the space in which the elevating lift moves up and down to a position facing the unstored storage room. When the trolley moves the stored object to the position facing the unstored storage room, the tray mounting part is moved up and down by the elevating means, so that the traversing tray of the storage room and the mounting part on which the traversing tray is not mounted face each other. I do. From this state, the traversing tray in the storage room is placed on the placing portion by the tray placing means.

Thereafter, the loading section is moved up and down again by the lifting means, so that the traversing tray on which the stored items are placed faces the storage chamber. From this state, the traversing tray on which the stored items are placed is lowered into the storage room by the tray lowering means. Thereby, the storage thing is stored in the storage room.

According to the fifth aspect of the present invention, since the storage chambers are provided on both sides of the traveling passage, the storage of the stored items can be performed more quickly.

As shown in FIGS. 1, 2 and 8, the parking room 4 of each of the storage towers 1A to 1D is partitioned by a roller frame 13. Each roller frame 13 supports a plurality of rollers 14. The roller 14 is positively rotated by a motor (not shown). That is, this roller 14
The traversing tray 6 is placed on the upper side, and the traversing tray 6 reciprocates right and left with the rotation of the roller 14. Further, a roller frame 13 supporting the rollers 14 is provided before and after each floor in the elevating space 5.

As shown in FIG. 4, the traversing tray 6 has a substantially H-shaped tray frame 15 and the tray frame 15.
Are formed from a comb-shaped fork 17 projecting from both sides of the fork. The fork 17 of the traversing tray 6 is formed alternately with the fork 16 of the lift 8 so as not to interfere with the fork 1 formed on the lift 8. Each of the traversing trays 6 traverses between the parking room 4 and the traveling passage 2 as the rollers 14 rotate.

As shown in FIG. 5, running rollers 19 are provided at both front and rear ends of a frame 18 constituting the carriage 3. The roller 19 is positively rotated by a drive motor (not shown). Thereby, the bogie 3 runs on the traveling passage 2 by itself. In addition, the front, rear, left and right 4 of the frame 18 of the carriage 3
Hydraulic cylinders 20 as elevating means are mounted and fixed at the locations. Piston rod 21 of the same hydraulic cylinder 20
The first tray receiving bracket 22 is attached and fixed to the tip of the first tray. The first tray receiving bracket 22 is provided with a plurality of pairs of front and rear tray moving rollers 23 constituting a tray mounting unit and a tray lowering unit.
Are positively rotated by a drive motor (not shown).

Further, the first tray receiving bracket 2
A second tray receiving bracket 24 is attached and fixed to the upper part of the second tray 2. The same bracket 24 is provided with a plurality of tray moving rollers 23 similarly to the first tray receiving bracket 22. The roller 2 between the first tray receiving bracket 22 and the second tray receiving bracket 24
3 are each driven and controlled. A space is provided between the first tray receiving bracket 22 and the second tray receiving bracket 24 to allow the transverse tray 6 to enter and exit. Incidentally, the pump driving the respective drive motor and the hydraulic cylinder 20 is adapted to be driven by power applied from the laid feeding line (not shown) on the travel through path 2.

As shown in FIG. 7, the hydraulic cylinder 20
During the contraction, the uppermost outer peripheral surface of the tray moving roller 23 of the second tray receiving bracket 24 and the roller 14 of the roller frame 13 in the parking room 4 and the elevating space 5 is substantially the same height. Also, as shown in FIG.
When 0 is extended, the uppermost outer peripheral surface of the tray moving roller 23 of the first tray receiving bracket 22 and the roller frame 13 of the parking room 4 becomes substantially the same height. Therefore, the traveling passage 2 is formed at a position lower than the parking room 4.

The motors and winches are automatically controlled by a controller (not shown). Next, an operation when the vehicle C enters the warehouse will be described.

It is assumed that the traversing trays 6 are arranged in all the parking rooms 4 and that the traversing trays 6 are already mounted on the first tray receiving brackets 22 of the cart 3.

For example, when storing the vehicle C in the parking room 4 on the second floor, the vehicle C is first entered into the entry / exit room 7.
At the same time, the carriage 3 arranged in the traveling passage 2 on the second floor is moved to a position facing the lift elevating space 5, that is, to the storage tower 1A (see FIG. 8). When the cart 3 reaches the storage tower 1A, the tray moving roller 23 and the roller frame 1
The roller 14 is rotated to lower the traversing tray 6 from the first tray receiving bracket 22 to the lift elevating space 5 (see FIG. 9). Next, the lift 8 is lowered to a position lower than the horizontal tray 6 arranged in the lift space 5. As a result, the vehicle C transfers from the lift 8 to the traversing tray 6 (see FIG. 10).

At the same time, the piston rod 21 of the hydraulic cylinder 20 is contracted, and the second tray receiving bracket 2
4 and the traversing tray 6 in the lift elevating space 5 are opposed to each other. Then, the roller 23 of the second tray receiving bracket 24 and the roller 14 of the roller frame 14 are turned over,
The traversing tray 6 is placed on the second tray receiving bracket 24 (see FIG. 11). When the placing of the traversing tray 6 on which the vehicle C is placed on the second tray receiving bracket 24 is completed, the trolley 3 is moved from the lift elevating space 5 to the nearest storage tower opposite the parking room 4 where no vehicle is stored. here,
For example, in a case where the parking room 4 not containing a vehicle closest to the lift elevating space 5 is the parking room 4 of the storage tower 1B, the carriage 3 is moved from the storage tower 1A to the storage tower 1B (see FIG. 12).

When the bogie 3 moves to the storage tower 1B, the piston rod 21 of the hydraulic cylinder 20 is extended to
The tray receiving bracket 22 of the vehicle and the traversing tray 6 in the parking room 4 are opposed to each other (see FIG. 6). Then, the tray moving roller 23 of the first tray receiving bracket 22 and the roller 14 of the roller frame 14 are rotated, and the traversing tray 6 in the parking room 4 is placed on the first tray receiving bracket 24. When the placing of the transverse tray 6 on the first tray receiving bracket 24 is completed, the piston rod 21 is contracted, and the second tray receiving bracket 24 and the parking room 4 are opposed to each other (see FIGS. 7 and 13). Then, the tray moving rollers 23 of the second tray receiving bracket 24 and the rollers 14 of the roller frame 14 are rotated, and the traversing tray 6 placed on the second tray receiving bracket 24 is lowered into the parking room 4. Thus, the vehicle C is stored.

As described above, in this embodiment, two stages (the first tray receiving bracket 22 and the second tray receiving bracket 24) for mounting the traversing tray 6 on the carriage 3 are provided. Each of the brackets 22 and 24 has a transverse tray 6.
Are provided, respectively, for moving the tray. Thereby, since the transverse tray 6 can be always placed on the carriage 3, the vehicle C can be quickly moved in and out.

That is, in this embodiment, when the vehicle C is to be stored in the vehicle, the number of movements of the carriage 3 is only two (see FIG. 14). On the other hand, in the prior art, when the vehicle is stored, the number of movements of the bogie is four (see FIG. 15). As is apparent from the number of movements of the trolley 3, the number of movements of the trolley 3 is smaller in the present embodiment than in the related art, so that the vehicle C can be quickly stored. Further, in the prior art, the traversing tray on which the vehicle is mounted must be lowered to the original parking room. On the other hand, in the present embodiment, the traversing tray 6 on which the vehicle C is mounted can be placed in the parking room 4 in which the vehicle is not stored, which is closest to the lift elevating space 5. As described above, in this embodiment, the moving distance of the carriage 3 is also shortened, so that the vehicle C can be stored more quickly.

Further, in this embodiment, unlike the prior art, the traveling passage 2 is constructed on a flat surface by laying concrete without using guide rollers, so that the strength of the traveling passage 2 can be sufficiently maintained. . Thereby, even if the cart 3 is run at a high speed, the traveling passage 2 is not damaged, so that a smoother entrance / exit can be performed.

As described above, in the present embodiment, the time required for entering and leaving the vehicle can be greatly shortened as compared with the prior art, so that it is possible to increase the number of vehicles C entering and leaving within a prescribed time. It is possible to increase the number of stored vehicles C, that is, the number of parking rooms 4.

It should be noted that the present invention is not limited to the above embodiment, but may be configured as follows, for example, without departing from the spirit of the invention. (1) The traversing movement of the traversing tray 6 is performed using a device such as an actuator that performs a linear reciprocating motion. In addition, the movement of the traversing tray 6 should be self-propelled like the carriage 3.

(2) In the above embodiment, the storage system is embodied in a multilevel parking garage, but may be embodied in a storage system or the like for storing luggage such as cardboard boxes. (3) Tray receiving bracket 2 as a mounting portion for the cart 3
The number of stages 2, 24 must be three or more. in this case,
Piston rod 2 of hydraulic cylinder 20 as lifting means
1 is used that can expand and contract in accordance with the number of stages of the mounting portion.

(4) In the above embodiment, the hydraulic cylinder 20
Although the lifting means is constituted by the above, instead of this, the tray receiving brackets 22 and 24 may be moved up and down by a mechanism such as a gear mechanism, a chain mechanism and a rack & pinion mechanism.

(5) In the above embodiment, the parking room 4 is provided on both sides of the traveling passage 2, but the parking room 4 may be formed only on one side of the traveling passage 2 to embody the present invention.

[0042]

As described in detail above, according to the present invention,
Since the number of times of movement and the moving distance of the cart can be reduced, there is an excellent effect that storage and retrieval of stored items can be performed quickly in a short time.
