Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a conveyor and a multi-story parking lot using the conveyor.

[0002]

2. Description of the Related Art In recent years, mechanical parking facilities have been widely used in order to efficiently transport and park vehicles by using mechanical devices instead of self-propelled vehicles in urban spaces. Among these mechanical parking facilities, parking facilities (multi-story parking lots) of the elevator slide type are often used in consideration of the number of accommodations. This elevator slide type parking facility combines an elevator type elevating device with a slide type conveyor and stores the vehicle three-dimensionally.

[0003] In this kind of parking lot, for example, vehicles are transferred between an entrance / exit berth and an entrance / exit lift, or between an entrance / exit lift and a traveling vehicle, and between a traveling vehicle and a storage shelf. Most of them are slat conveyors or roller conveyors.

[0004]

However, since the slat conveyor and the roller conveyor described above bear the load by the slats and rollers supported at both ends, the slat conveyor and the roller conveyor must be manufactured firmly in terms of material and size. In particular, in the case of a roller conveyor, there is a problem in that the cost must be increased because the bearing must be manufactured firmly.

[0005] Further, both have a problem in that they cannot be used in a multistory parking garage for storing large vehicles such as trucks because the above-mentioned support structure has a limit in the load they can bear, and they lack versatility.

[0006] Further, both have a problem that smoothness is difficult and noise is large because relatively large slats and rollers circulate and rotate.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a highly versatile conveyor capable of reducing cost and noise and a multi-story parking lot using the conveyor.

[0008]

In order to achieve the above-mentioned object, a conveyor according to the present invention has a plurality of rolling elements arranged on a fixed table so as to be able to roll in a desired direction. A load placed over the rolling element is transferred in the rolling direction of the rolling element.

In addition, the left, circulating on the fixed table,
A plurality of shafts are laterally suspended between the right and left chains at predetermined intervals in the circulation direction, and the rolling elements are supported on the shafts.

[0010] The chain is driven by a motor.

[0011] Further, the left,
A tension cross is provided so as to cover the fixed table by being supported between the right-toothed belts and to be able to circulate, and the rolling element is interposed between the tension cross and the fixed table.

Further, a multi-story parking garage according to the present invention is characterized in that the above-mentioned conveyor is used for transferring incoming and outgoing vehicles.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a conveyor according to the present invention and a multi-story parking lot using the conveyor will be described in detail with reference to the drawings using embodiments.

An entrance 21 and an exit 22 are provided above the elevators 17 and 18, and an entrance berth 23 and exit berth 24 are provided adjacent to the entrance 21 and exit 22. ing.

Each of the storage shelves 11, 12, 13, 14
Further, a conveyor 25 described later for transferring the vehicle is installed on each of the traveling vehicles 15 and 16, each of the lifts 19 and 20, and each of the berths 23 and 24.

As shown in FIG. 6, at the level where the entrance 21 and the exit 22 are provided, the entrance 2 of the vehicle 10 is connected to the entrance berth 23 adjacent to the entrance 21.
6 is provided, and a mirror 27 having a parking instruction lamp is provided in front of the storage berth 23.

On the other hand, an exit path 28 of the vehicle 10 is provided so as to be connected to an exit berth 24 adjacent to the exit 22. A pedestrian passageway 29 is provided between the entrance berth 23 and the exit berth 24 for occupants whose safety is ensured so that the vehicle 10 cannot enter.

The conveyor 25 is, as shown in FIG.
Chains 3 are arranged via sprockets 2 on both left and right sides of a fixed table 1 whose front and rear ends are curled downward in a semicircular shape so as to be circulated by driving a motor 4. The rolling elements 6 are mounted on a plurality of shafts 5 laid horizontally in the front-rear direction (circulation direction) at predetermined intervals.
Are supported in a skewered manner so that the rolling elements 6 can roll on the fixed table 1 in the circulating direction by the circulation of the chain 3.

In the illustrated example, the rolling element 6 is formed of a small ball made of rubber or nylon. However, the rolling element 6 may be in the form of a short cylinder or an abacus ball. But it is good.

The rolling element 6 is not provided over the entire length of the chain 3, and the rolling element 6 starts to rotate from a state where the vehicle 10 as a load is placed, and moves the vehicle 10 onto the adjacent conveyor 25. It is provided over the range up to mounting.

[Operation] With this configuration, when the vehicle 10 is stored in this mechanical multi-story parking lot, the entrance 2
The vehicle 10 that has entered from 6 stops on the berth 23, and the occupant gets off here.

The vehicle 10 on the storage berth 23 is moved by the conveyor 25 under the control of a computer.
, And descends to a predetermined level by the storage elevator 17.

Then, for example, in the storage shelf 11, the vehicle 1
0 is transferred from the elevating lift 19 to the traveling carriage 15 by the conveyor 25, and the traveling carriage 15 is moved to a predetermined position.

Here, the vehicle 10 is transferred from the traveling cart 15 to the storage shelf 12 by the conveyor 25. On the other hand, the occupant receives the parking ticket, passes through the pedestrian passage 29, and goes out of the building.

When the vehicle is taken out of the mechanical multi-story parking lot, the occupant goes to the exit berth 24 through the pedestrian passage 29 and inserts a parking ticket at a predetermined insertion position.

Then, a predetermined vehicle 10 is searched by computer control. For example, the vehicle 10 stored in the storage shelf 14 is transferred to the traveling carriage 16 by the conveyor 25,
The traveling carriage 16 is moved to the exit elevator 18.

Then, the vehicle 10 is transferred by the conveyer 25 to the retrieval elevating lift 20 and rises to the retrieval opening 22, where it is transferred to the retrieval berth 24 by the conveyor 25. On the other hand, the occupant gets on the vehicle 10 stopped at the exit berth 24 and exits through the exit route 28.

By the way, in the conveyor 25 of this embodiment,
As shown in FIG. 2, the rotation of the rolling element 6 causes the vehicle 10 to move at twice the moving speed V of the rolling element 6 (the rotation speed of the sprocket 2), so that the entry and exit operations can be speeded up. .

Further, in the conveyor 25, since the fixed table 1 bears a load, the fixed table 1 can withstand a large load, and can be used in a multi-story parking lot for storing large vehicles such as trucks, thereby increasing versatility. In addition, since the rolling elements 6 do not require precision or strength, cost reduction can be achieved by weight reduction and mass production. Further, even when the motor 4 is driven, the driving force is small due to the rolling friction and the noise is small.

Further, in the conveyor 25, a plurality of shafts 5 are horizontally laid between the left and right chains 3 circulating on the fixed table 1 at predetermined intervals in the circulating direction. Since the rolling elements 6 are supported at the same time, a plurality of rolling elements 6 can be aligned and reliably rolled in an arbitrary direction.

Since the chain is configured to be driven by the motor 4, the speed and position of the conveyor 25 can be easily controlled.

In the above embodiment, the example in which the chain 3 is driven by the motor 4 is shown. However, the vehicle 10 is directly handed (by a robot hand or the like) without driving the motor 4 and the rolling element 6 is driven. You may slide it up. According to this, the diameter of the shaft 5 can be reduced.

Although the rolling element 6 is supported on the shaft 5 driven by the chain 3, if the rolling element 6 is configured to be able to circulate and guide on the fixed table 1 like a ball screw, the chain 3 is driven. It does not need to be supported on the shaft 5 which is formed.

[Second Embodiment] FIG. 3 is a perspective view of a conveyor according to a second embodiment of the present invention, and FIG. 4 is a sectional view taken along line IV-IV of FIG.

[Construction] In this embodiment, the conveyor 25 of the first embodiment is provided with a toothed belt 3A via pulleys 2A on both left and right sides of a fixed table 1A formed in an oval shape.
Are circulated by a motor drive or the like, and
Two tension bars 7a, between the right double toothed belt 3A,
A tension cross 8 is disposed so as to be circulated while supporting the fixed table 1A while supporting the fixed table 1A through a support 7b. A number of free rollers 6A as rolling elements are interposed between the tension cloth 8 and the fixed table 1A. It is configured.

It is preferable that the tension cloth 8 is formed in a mesh shape and the free roller 6A is formed of a synthetic resin material. Other configurations are the same as those of the first embodiment.

[Operation] Also in this embodiment, the toothed belt 3A is driven by a motor or the like, and the free roller 6A is rotated via the tension cloth 8, thereby facilitating a large vehicle with a large driving force with a small driving force. And the same operation and effect as those of the first embodiment can be obtained. Also,
In this embodiment, since the free roller 6A is covered with the tension cloth 8, there is also an advantage that dust and the like hardly adhere to the free roller 6A.

The present invention is not limited to the above embodiments,
It goes without saying that various changes can be made without departing from the spirit of the present invention.

[0042]

According to the first aspect of the present invention, a plurality of rolling elements are arranged on a fixed table so as to be able to roll in a desired direction, and are mounted on the plurality of rolling elements. Since the configured load is transferred in the rolling direction of the rolling element,
Since the fixed table bears the load, the fixed table can withstand a large load, and can be used in a multi-story parking lot for storing large vehicles such as trucks, thereby increasing versatility. Further, since the rolling elements do not require accuracy or strength, cost reduction can be achieved by weight reduction and mass production.

According to the second aspect of the present invention, a plurality of shafts are horizontally suspended between the left and right chains circulating on the fixed table at a predetermined interval in the circulating direction, and the rolling elements are mounted on the shafts. Is supported, so that a plurality of rolling elements can be uniformly rolled in an arbitrary direction.

According to the third aspect of the present invention, since the chain is configured to be driven by a motor, it is easy to control the speed and position of the conveyor.

According to the fourth aspect of the present invention, a tension cross is provided between the left and right toothed belts circulating on the fixed table so as to cover the fixed table and to be circulable. Since the rolling elements are interposed between the rotary table and the fixed table, a plurality of rolling elements can be aligned and reliably rolled in an arbitrary direction. In addition, since the rolling elements are covered with the tension cloth, there is an advantage that dust and the like hardly adhere to the rolling elements.

According to the fifth aspect of the present invention, since the conveyors of the first to fourth aspects are used for transferring the incoming and outgoing vehicles, the speed of the incoming and outgoing operations can be increased with a small driving force.
