Description

[Detailed description of the invention] <Industrial application field> <Conventional technology> Currently, the following types of multi-story parking lots are known.

(a) Pallet-type multi-storey parking lot This is a parking lot that uses plates called pallets, as typified by, for example, Japanese Patent Application Laid-Open No. 129469/1982, and has sections on each floor that can accommodate cars. It is a multi-level parking lot in which each car enters or exits with a plate placed on it inside a building with space.

(b) Gondola-style multilevel parking lot This is a parking lot with a structure similar to a gondola at an amusement park.
An endless chain is wound between the large sprockets placed between the top and bottom, and gondolas are attached at equal intervals along the chain to circulate the desired gondola to the position closest to the ground. It is a multi-story parking lot where cars can enter and exit the parking lot.

<Problems to be Solved by the Present Invention> The conventional multi-level parking lot described above has the following problems.

<B> In multi-storey parking garages with pallet format, there are two types: one pallet is stored in each room of the shelf, and the pallet is loaded and unloaded by taking it in and out of the shelf, and the other type is a type where a large number of pallets are stored. There are two types: one in which pallets with cars placed on them are stored in shelves one after another each time they are put into storage, and the remaining pallets are piled up again when they are taken out.

In the former type, it is necessary to take out and take out only pallets from the shelves each time the goods come in or go out of stock, which requires a lot of effort and time.

The latter type requires a dedicated space for stacking pallets, making it difficult to utilize the space effectively.

In addition, for both types, it is necessary to drive the car straight onto the pallet and accurately so that the wheels do not protrude from the front and back of the pallet, making it troublesome and time-consuming to set up the car for storage.

In addition, in the case of a multi-storey parking lot with pallets, set the parking brake or put the transmission in gear to stop the vehicle placed on the pallet to prevent it from falling. It is considered a condition.

However, if the vehicle is not stopped properly, the vehicle may fall off the pallet during transfer, which is very dangerous.

In addition, even if the vehicle is reliably stopped, there is a risk that the vehicle will be thrown off the pallet if it is attempted to be transferred at high speed, so it is forced to operate at low speed.

Therefore, it takes a long time to enter and take out the warehouse.

<C> In the case of a gondola-type multi-story parking lot, in addition to the fact that the capacity for accommodating cars is small compared to the building site area, each gondola is arranged in series, so the desired gondola can be quickly reached from the ground. It takes time to enter and exit the warehouse because the vehicle cannot be moved to the entrance.

(2) Nowadays, it is not possible to construct an unlimited number of buildings above ground or underground, so there are inevitably restrictions on the total height of a multi-story parking lot.

Under these current circumstances, the carrying capacity of automobiles is becoming more efficient.
A proposal for a multi-level parking lot is desired.

<Object of the present invention> The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a method for storing vehicles without using pallets, which are troublesome to manage and set up for vehicle storage. An object of the present invention is to provide a conveyor in a multi-story parking lot that can enter and exit the parking lot.

A further object of the present invention is to provide a conveyor in a multi-story parking lot that prevents vehicles from falling and significantly improves the safety of parking and exit operations.

Another object of the present invention is to provide a conveyor for a multi-story parking lot that can carry out warehousing and warehousing operations at high speed.

<Configuration of the Present Invention> Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

<A> Overall description of multi-story parking lot Figure 4.5 shows an overall view of the multi-story parking lot 10 according to the present invention.

Inside the multi-story parking lot 10, there is an elongated central passage 11 and groups of parking rooms 12 formed on both sides of the central passage 11 in the vertical and horizontal directions.

The central passage 11 faces all parking spaces 12.

Reference numeral 13 denotes a door provided in a part of the central passage 11, which is opened and closed when a car enters or leaves the warehouse.

One door 13 serving as an entrance/exit may be used in common, or may be provided separately.

A conveyor 20 is accommodated in the central passage 11 so as to be movable in the vertical and longitudinal directions using transmission members such as belts and chains arranged in the vertical and horizontal directions, or by a known structure such as a rail system.

The movement and stopping of the carrier 20 is entirely controlled by a computer.

Each part will be explained below.

<Mouth> Transport body (Fig. 1) FIG. 1 shows a plan view of the carrier 20.

The carrier 20 is a dedicated device for loading and unloading vehicles, and includes an L-shaped loading table 21 and this loading table 2.
The basic components are a rotary table 22 rotatably placed on the rotary table 22 and an undercover crane device 30 placed on the rotary table 22 so as to be movable in and out.

As shown in FIG. 4, the rotary table 22 is configured to be able to rotate forward or reverse within a 180° range at a 90° position.
As the rotation table 22 rotates, the infiltration crane device 30
rotates.

<C> Infiltration crane device (Fig. 1) The infiltration crane device 30 is a thin device that can be infiltrated into the center of the lower part of the vehicle, and is equipped with four sets of swingable arms.
This is a device that slightly lifts and moves all wheels A and B while keeping these arms locked to the curved inner surfaces of each of the front and rear wheels A and B of the vehicle.

The undercover crane device 30 includes a frame 31 having a traveling function and an elevating function, and a pair of frames installed on both sides of the frame 31 to allow horizontal swinging and sliding in a limited area along the longitudinal direction of the frame 31. First swing arm 40.4
0 and a second arm 50.50.

<2> Swing mechanism and sliding mechanism of swing arm FIG. 2 shows the first and second swing arms 40 that can be locked to the front and rear wheels A and B of the vehicle.
．． 40.50.50 is a conceptual diagram showing an example of a swinging mechanism and a sliding mechanism.

Therefore, in FIG. 2, elements other than the swing mechanism are omitted.

In the figure, 41 is one of the two first sliding plates placed on the right side of the frame 31 in the drawing, and 51 is one of the two second sliding plates placed on the frame 31 on the left side of the first sliding plate. This is one of the moving plates.

42 is a stopper that restricts movement of the first sliding plate 41 to the right; 43 is a stopper with a limit switch that restricts movement of the first sliding plate 41 to the left; both stoppers 42. 43 is fixed to the frame 31.

A spring 44 always urges the first sliding plate 41 in the right direction in the drawing.

Therefore, the first sliding plate 41 moves between these two stoppers 42.4.
You will be sliding over a short section of 3.

45 is a first horizontal plate that imparts a swinging motion to the first swinging arm 40.40.

An arm piece 47.47 extending from a first arm 40.40 pivotally supported by a king pin 46 on the first sliding plate 41, and a first horizontal plate 45
A screw rod 260 whose both ends are connected by a pin is a threaded rod rotatably attached to the first slide plate 41, and its midway is screwed into the first horizontal plate 45.

Therefore, the pair of first swing arms 40.40 are connected to the threaded rod 6.
a first spline section 61 connected to the base end of the threaded rod 62; a second spline section 63 connected to the threaded rod 62;
The rotational force is transmitted from the swing motor M1 connected to the frame 31, and the frame 31 swings within a range of approximately 90° from a position along the longitudinal direction of the frame 31 to a position orthogonal to the frame 31.

Spline section 6 that transmits rotation while sliding in the axial direction
1.63 was adopted for both sets of swing arms 40.50
The first and second sliding plates 41.5 are
This is to allow the slider to slide.

The swinging mechanism of the second swinging arm 50.50 is the first swinging arm described above.
The swinging mechanism is basically the same as the swinging mechanism of the swinging arms 40.40, but a threaded rod 62 is screwed into the second horizontal plate 52, and both sets of swinging arms 40 are moved by the swinging motor M1 of the second side. .50
The structure is such that it is possible to simultaneously control the swinging of both.

53 is a stopper incorporating a limit switch, and the second
It is fixedly attached to the sliding plate 51, and detects when the swinging of both sets of swinging arms 40, 50 reaches the orthogonal position of the frame 31, and sends a rotation stop signal to the swinging motor M1. .

Further, in order to swing the second sliding plate 51 to which the second swing arm 50.50 is attached along the longitudinal direction of the frame 31, the following configuration is provided.

That is, the sliding motor M2 disposed at the left end of the frame 31
A threaded rod 64 extends from the rotating shaft.

A hollow guide member 54 is fixed to the left end of the second sliding plate 51.

A movable body 55 is slidably housed within the guide member 54, and the threaded rod 64 is screwed into the center of the movable body 55.

A spring 56 urges the movable body 55 to the right in the drawing.

The stopper 57 has a built-in limit switch and is attached to the opening side of the guide member 54.

The limit switch built into the stopper 57 is electrically connected to control the operation of the swing motor M2. Therefore, while the movable body 55 is away from the stopper 57, the sliding motor M2 rotates and the second motor M2 rotates. The sliding plate 51 is pulled in the direction in which the sliding motor M2 approaches, and the moving body 55 comes into contact with the stopper 57 to activate the limit switch (and the rotation of the sliding motor M2 stops, causing the second sliding plate 51 to slide). The movement stops.

In addition to the above-described rocking mechanism for the two sets of rocking arms 40 and 50, a known mechanism such as a gear type or a hydraulic cylinder type may be adopted.

<E> Frame elevating mechanism (Fig. 1.3) Fig. 3 shows an example of a mechanism capable of elevating the frame 31 together with both sets of swing arms 40 and 50.

This example utilizes a plurality of sets of sprockets 70 having body lengths and a plurality of sets of bolts 71 that screw together each sprocket 70 so as to be able to move up and down.

That is, on the upper and lower sides of both ends of the frame 31, two sheets 1! The board is placed at Jl.

The plate body 32 located above the frame 31 is integrally fixed to the frame 31 by welding or the like.

A board 33 located below the frame 31 has running wheels 34 at both ends, and a plurality of bolts 7 on its top surface.
1 is planted.

A long sprocket 70 is screwed into each bolt 71, respectively.

In this embodiment, two sets of sprockets 70 are arranged on each side of the frame 31, for a total of four sets. An endless chain or belt (not shown) is wound between these sprockets 70, and some sprockets 70 are connected to motors, etc. If a rotational drive source is connected, all groups of sprockets 70 can be raised and lowered simultaneously by normal rotation or reverse rotation of some of the sprockets 70, thereby vertically moving both sets of swing arms 40 and 50 together with the frame 31. Can be done.

Note that 72 is a bearing interposed between each sprocket 70 and the plate.

In addition to the example described above, the elevating and lowering mechanism of the frame 31 may employ a known mechanism such as a system using a cylinder that expands and contracts by fluid pressure.

Kube> Advancement and retreat structure of the infiltration crane device (Fig. 1) In order to provide the infiltration crane device 30 with a running function, for example, the running wheels 34 are configured to be self-propelled, or the infiltration crane is installed under the rotary table 22. A mechanism may be employed in which a belt member that moves along the forward and backward direction of the device 30 is arranged, and the tail end of the undercover crane device 30 is connected to a part of this belt member to apply running force.

<G> Since the movement of the automatically controlled conveyance body 20 can be grasped coordinately using a computer, the data of each parking room 12 is inputted into the computer in advance, and in order to detect the stop position of the movement of each member. By placing these sensors in appropriate locations, all operations within a multi-story parking lot can be automatically controlled.

<Effect> Next, the operation of the multi-story parking lot having the above structure will be explained.

(The warehousing operation is performed.) When entering a vehicle, the driver must move the vehicle to the door 1 shown in Figure 4.
Stop outside No. 3, pull the parking brake, and get off.

At this time, the carrier 20 is waiting inside the door 13.

<Exit> The levitation door 13 of the incoming vehicle opens (and the infiltration crane equipment f
f130 moves forward from above the rotating table 22 toward the center of the lower part of the vehicle.

When the crawler crane device 30 smoothly crawls into the center of the lower part of the vehicle, both swing arms 40, 50 are closed so as not to impede the crawler.

When a sensor (not shown) attached to the submerged crane device 30 detects that the second swinging arm 50.50 has passed to the front wheel, both swinging arms 40.40. 50.50 is opened by swinging 90 degrees between the inside of both wheels A and B of the vehicle.

Next, with both swing arms 40, 40, 50, 50 widened by 90°, the undercover crane device 30 continues to move forward at low speed,
At the same time, the second sliding plate 51 slides toward the front wheel A.

When the pair of first swing arms 40 and 40 come into contact with the curved inner peripheral surface of the rear wheel B as the infiltration crane device 30 moves forward,
The advance of the undercover crane device 30 is stopped.

As the second sliding plate 51 slides toward the front wheel A, the second swing arm 50.50 comes into contact with the inner peripheral surface of the front wheel A.
The sliding plate 51 stops sliding.

The mechanism for stopping the sliding of both sets of swing arms 40 and 50 has already been explained based on FIG.
The explanation will be omitted.

When the process of locking both sets of swinging arms 40.50 to the inner peripheral surfaces of the front wheel A and rear wheel B, respectively, is completed, the frame 31 floats up, and both sets of swinging arms 40.50 are integrated with the frame 31.
50 slightly lifts all wheels A and B.

The amount of rise of the frame 31 is 40.50 for both sets of swing arms.
The front wheel A and the rear wheel B, which are locked and gripped, are at a slight height away from the floor surface.

The weight of the vehicle is supported by the running wheels 34 via each sprocket 70 and bolt 71.

(c) Pulling in the warehouse vehicle Next, as shown in FIG. 1, the infiltration crane device 30 is retreated to pull the vehicle onto the rotary table 22 while keeping the vehicle floating.

(2) The transport body 20 carrying the transport vehicle of the passenger vehicle moves through the shortest distance from the position of the door 13 to the front of the parking room 12 where it is scheduled to enter.

Until the conveyor 20 stops in front of the parking room 12 scheduled to enter, the rotary table 2 rotates 90'' toward the parking room 12 scheduled to enter, changing the direction of the vehicle.

Since both sets of swinging arms 40, 50 reliably sandwich the inner peripheral surfaces of all wheels A and B of the vehicle, high-speed movement of the vehicle is possible.

<E> When the warehousing transport body 20 stops in front of the destination parking room 12, the sneak crane device 30 advances toward the parking room 12 with the vehicle still mounted thereon.

When the carrier 20 transports the vehicle to a fixed position in the parking room 12, the infiltration crane device 30 stops.

Next, hold the frame 31 while holding all the wheels A and B.
descends.

Then, the vehicle slowly descends together with the frame 31, and the front wheels A and rear wheels B, which had been floating until then, land in the parking room 12.

Next, each arm 40. which was locked to the front wheel A and the rear wheel B.
50 is closed and housed in the frame 31, the infiltration crane device 30 is pulled out from the center of the lower part of the vehicle, and the carrying object 20 is removed.
Pull back to.

The vehicle is left in the parking lot 12 as it is, and the warehousing work is completed.

<Go> Return process After the infiltration crane device 30 is pulled back to the carrying body 20, the rotating table 22 is moved 90” before moving to the front of the door 13.
The direction of the infiltration crane device 30 is changed by reversing the direction.

The carrier 20 closes the door 13 for the next warehousing or unloading operation.
Wait until in front of.

(If) The unloading operation is different from the above-mentioned warehousing operation, except that the position where the vehicle is lifted and the position where the vehicle lands on the floor are different, and the basic operation of the carrier 20 is the same.

Therefore, a description of the unloading operation will be omitted.

<Other Examples> In the above embodiments, the case where the 12 groups of parking spaces are provided on both sides of the central passage 11 has been described, but the structure in which the 12 groups of parking spaces are provided only on one side, or the structure in which the 12 groups of parking spaces are provided on both sides, or the case where the central passage has 12 groups of parking spaces on both sides has been described. 1
It may be a multi-story parking lot in which a plurality of sets of 1 are provided and a transport body 20 is provided for each central passage 11.

<Effects of the Present Invention> Since the present invention is as described above, the following effects can be obtained.

<A> - All vehicles can be stored and taken out with just one hidden crane device.

Therefore, there is no need to use a single pallet, which is troublesome to manage.

<Exposure> Since it is gripped by locking onto the inner circumferential surface of each wheel of the vehicle, there is no risk of the vehicle falling over even if the conveyor is moved at high speed, making it safe and capable of high-speed operation. .

<C> The height of the parking room can be designed to be low because the wheels are simply raised to a height that is off the floor.

(2) It is easy to apply to above-ground, underground, or semi-underground parking structures.
