Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement in a multi-story warehouse for storing automobiles, which enables efficient loading and unloading of automobiles.

[Prior art and its issues] In general, the requirements for multi-level warehouses are how to efficiently store goods within a narrow site, how to efficiently carry out loading and unloading, and how to shorten the time required for this process. It is.

Furthermore, it is a technical issue how to best meet the above requirements depending on the type of article. In the case of automobiles being handled in particular, the newly manufactured cars are driven by the driver to a designated location in the warehouse. The methods are different. Therefore, it must be easy for the driver to carry in and out.

Also, in connection with the above, some car models have right-hand drive and left-hand drive, and consideration must be given to avoid damaging new cars.

A conventional multi-level warehouse for storing automobiles is shown and explained in FIG. This three-dimensional warehouse is a car hangar 1 in which parallel storage shelves 2 are arranged. Car loading section 10 and loading section 9
In this case, the loading and unloading lines are spaced apart and each line is separated. The reason for this separation is that when loading and unloading, the driver opens and closes the door when entering or exiting the car, so this door should not hit the neighboring car. This is because it is necessary to maintain a sufficient distance between adjacent vehicles in order to facilitate the entry and exit of drivers.

In addition, the carrying-in section 10, the carrying-out section 9, and the hangar 1
An endless annular rail 4 is laid between the two and is configured to receive and deliver automobiles.

In the conventional multi-storey vehicle storage warehouse configured as described above, loading and unloading is carried out as follows. First, a car brought in from the carry-in section 10 is placed on a pallet 8. This palette 8
While being loaded onto the trolleys 5-1 to 5-7, among the trolleys 5-1 to 5-7 that are moving on the rails 4, the rear of the trolleys 5-1 to 5.7 that are being transferred is The approaching truck will stop temporarily. That is, in the state shown in the figure, if a car is being transferred between the truck 5-1 and the pallet 8-1, the truck 5-2 and the pallet 8-2,
The trolley 5-3 and the unloading conveyor 6-3 are temporarily stopped.

Next, the carts 5-1 to 5-7 are moved along the rails 4, stopped in correspondence with the parallel retractable shelves 2 to be stored, lowered the car, and scooped it up with the stacker crane 3 and placed it in a predetermined position. Each pallet is stored in a storage shelf. While the cars are being unloaded from these bogies 5-1 to 5-7, the following approaching bogies are temporarily stopped, as described above.

On the other hand, in case of shipping, it is done as follows. The stored automobiles are scooped up along with the pallet 8 by the stacker crane 3, and placed on the carts 5-1 to 5-5.
7 (hereinafter, such a delivery place is referred to as the delivery origin), the car is unloaded here, and delivered to the trolleys 5-1 to 5-7. For example, in the figure, the delivery origin 2 of the parallel storage type shelf 2
Transfer between -1 and trolley 5-5. Next, the cart 5-5 is moved, stops at a vacant place in the carry-out section 9, and is delivered to the carry-out conveyor 6. In this state, the vehicle is facing backwards, so the vehicle is turned around by the turntable 7 and carried out by the driver. In this case as well, when transferring from the cart 5-5 to the conveyor, the remaining carts are temporarily stopped in the above state.

Next, when operating a warehouse, there are cases in which the above-mentioned loading and unloading are carried out simultaneously, or cases in which only a large amount of loading and unloading is carried out.

For example, to explain the case where loading and unloading are carried out at the same time, in the state shown in the figure, in the loading section 10, the cart 5-1 and the pallet 8-1, in the loading section 10, the cart 5-2 and the pallet 8-2, and in the unloading section 9, , trolley 5
-3, unloading conveyor 6-3, and trolley 5-
4 and an unloading conveyor 6-4 (this cart 5-4 and an unloading conveyor 6-4 are used to collect empty pallets 8), and on the hangar 1 side, an origin 2-1, an unloading conveyor 6-4, and an unloading conveyor 6-4. 2-2 and the trolley 5-6, and the origin 2-3 and the trolley 5-7 must be connected to each other during work. For example, if there is a delay in the delivery between the cart 5-1 and the pallet 8-1 in the loading section 10, all other parts will be affected,
Loading and unloading will take time.

In the above explanation, the bogies 5-1 to 5-7 running on the annular rail 4 have been described as moving in a constant connection.
Since it is not possible to overtake the other bogies, the other bogies have to wait during that time, which also takes a long time, and if one of the bogies 5-1 to 5-7 breaks down, it will affect the whole truck. It will affect you.
Further, a balance must be maintained between the processing capacity of the carry-in section 10 and the carry-out section 9 and the processing capacity inside the hangar 1.

For example, when shipping automobiles, a situation arises in which a large number of automobiles must be delivered in a short period of time. In such a case, to explain using the example shown in the figure, 11 stacker cranes 3 are operated in the hangar 1 to carry the cars to the delivery origin and wait, but in the unloading section 9, It only has the capacity to carry out 4 vehicles.

In other words, the processing capacity in the hangar 1 is 11, whereas the processing capacity in the unloading section is 4, and the balance between the two cannot be maintained, and in the end, the processing capacity of this warehouse is
It will be evaluated as the processing capacity of 4 machines. At the same time, the same can be said for the case of import.

In this way, the balance between the processing capacity within the hangar and the processing capacity of the loading/unloading section (this is referred to as warehouse equipment efficiency) greatly influences the efficiency of the warehouse. For example, in this example, it can be calculated to be approximately 50% (11 stacker cranes and 4 loading/unloading units).

As explained above, in conventional multi-level car storage warehouses, circular rails are laid down, which requires extra space, and the trolleys that move on the circular rails have to be moved intermittently. In addition, it will take time in connection with other deliveries, and if the cart stops moving for some reason, the entire function will be lost.
There were also issues such as low warehouse efficiency.

An object of the present invention is to provide a three-dimensional automobile storage warehouse that solves all the above-mentioned conventional problems.

[Means for Solving the Problems] The present invention solves the problems of the prior art by arranging a plurality of rows of right-angled storage shelves for storing cars perpendicular to the rows of shelves, and by arranging the right-angled storage shelves. A stacker crane is installed between the shelves to scoop up automobiles pallet by pallet and store or carry them out on a predetermined right-angled storage shelf, and this stacker crane is connected at the origin to a trolley on which the automobiles are loaded together with the pallet. In a multi-story automobile storage warehouse, a rail for running a bogie is provided on each extension of each row of right-angled storage shelves provided in the automobile hangar, and a rail for running a bogie is provided on each of the rails for running the bogie. , and one truck equipped with a turntable for adjusting the direction of the vehicle.

[Function] That is, the present invention uses a so-called right-angled storage type shelf, in which cars are stored perpendicular to the row of shelves, instead of the conventional parallel storage type, and the distance between cars at the loading/unloading section is reduced. In addition to making it possible for the shelves to be removed, trolleys for loading and unloading are installed corresponding to each row of shelves.
This system is designed to reduce the installation space and improve warehouse efficiency, with multiple rows of right-angled retractable shelves and rails for running trolleys laid on the extensions of the multiple rows of right-angled retractable shelves. A trolley equipped with a turntable that runs on the rails is installed to deliver and deliver automobiles, and a stacker crane is installed that runs between the rows of the right-angled retractable shelves. In addition, regarding the operation of pallets, the vehicle loading department,
Basically, pallets are not accumulated at the unloading section.
Empty pallets that occur are immediately returned to the shelves, and empty pallets are retrieved from the shelves when needed, and no special equipment is installed to operate the pallets.In other words, vehicles are continuously carried out. Sometimes, empty pallets generated during unloading are returned to the shelf while the next unloading vehicle is being picked up.
When carrying in a series of deliveries, a car is placed on an empty pallet taken out from the shelf for loading, and after storing this, a nearby empty pallet is taken out and the next car is picked up. When loading and unloading are mixed,
The system utilizes the back-and-forth movement of the stacker crane without wasting any waste by placing an incoming vehicle on an empty pallet after being carried out, storing it, and then taking out the next unloading vehicle.

[Example] An example of the present invention will be described in detail below. Figure 2 shows the hangar plan. In the figure, the hangar 1 is composed of a plurality of rows of right-angled storage shelves 2a. For example, in this example, 1
Two right-angled retractable shelves 2a are arranged. 3 is
This is a stacker crane that travels between rows of right-angled storage shelves 2a. 11 is a rail for running the bogie;
It is provided on an extension of each row of right-angled storage shelves 2a.

FIG. 3 is a diagram showing the delivery origin in detail. In the figure, reference numeral 15 is a truck that runs on the rails 11. This trolley 15 is provided with a turntable 18 so that it can rotate with a car 16 placed thereon. Further, as shown in the center of the figure, the distance between the adjacent rails 11 is regulated by the right angle retractable shelf 2a, and the trolley 1
The dimensions are such that even if a car 16 is placed on the car 5 and turns, they will not come into contact with each other. That is, the reason why the distance between the rails is ensured in this way is that the storage shelf is a right-angled storage shelf 2a. Reference numeral 12 denotes a stopper for positioning the automobile at a predetermined position on the pallet 17. This stopper 12 is installed in the drive device 1 according to the dimensions of the vehicle that has been brought in.
3, it is set at a predetermined position in the longitudinal direction, and when the trolley 15 starts, it is turned and retracted and driven so as not to hinder running. Reference numeral 14 denotes a wheel guide member for determining the direction in which the vehicle approaches, and the driver drives the vehicle aiming at this guide member 14 and places the vehicle on a predetermined position on the pallet 17.

FIG. 4 and FIG. 5 are diagrams showing a stacker crane. Figure 4 (side view) and Figure 5
In the figure (front view), the stacker crane 3 is
Two masts 19 and a car 16 on a pallet 17
Fork 21 with a telescopic mechanism that scoops up
and a hoisting device 25 for vertically moving the automobile 16 scooped up by the fork 21 to a predetermined height.

That is, the stacker crane 3 is moved to a predetermined position, the fork 21 is extended and the car 19 is scooped up along with the pallet 17, and then the fork 21 is extended.
The vehicle 16 is retracted, the vehicle 16 is held between the masts 19, and the vehicle travels to a predetermined position.

In addition, in the figure, 20 is a carriage, and 22 is a rail 2.
A traveling device 23 is a control panel for the stacker crane connected to the central control device, and is controlled by a computer, and is used to control the running of the stacker crane 3 and the hoisting device 25.
and the fork 21 are respectively performed, and the loading and unloading is performed as instructed.

The operation of this embodiment configured as above will be explained next.

First, a case where loading and unloading is performed arbitrarily will be explained. The inside of the hangar 1 is managed by a computer. For example, information such as which shelves are currently empty or which car models are stored on which shelves is stored.

For example, when storing a certain type of car,
The driver enters into the computer by card,
You will be directed to the gate for warehousing. In FIG. 6, for example, the driver is directed to gate No. 7 and drives the automobile 16 to that gate.

In Figure 3, pallet 17 (placed on trolley 15) is waiting at gate No. 7.
Place the car 16 on top of it. At this time, stopper 1
2, the vehicle is placed in a predetermined position, and the driver applies the handbrake. Next, the stopper 12 is moved back a little by the drive device 13 (in the direction of pushing the car), and after confirming that the car 16 is completely braked, it is released.

Next, the trolley 15 travels to a predetermined position. After that, the turntable 18 is rotated, and the car 1
6 is perpendicular to the shelf row, travels to the delivery origin, and stops. Then, it is scooped up by the stacker crane 3 and stored on a predetermined empty right-angled storage shelf 2a specified by the computer.

In Fig. 3, at the No. 5 gate, it is scooped up by the stacker crane 3 and held between the masts 19, and at the No. 6 gate, the cart 15 is scooped up and held between the masts 19.
At No. 7 gate, the vehicle 16 is being transported to a predetermined location and being rotated by a turntable, and at No. 8 gate, the vehicle 16 is being placed on the pallet. The vehicle 16 has been carried to a predetermined location by the vehicle, the direction change of the vehicle 16 has been completed, and the vehicle 16 has arrived at the delivery origin and is about to be scooped up by the stacker crane 3.

In this way, each gate is independently operated and stored. In addition, the same process is performed in the case of leaving the warehouse. For example, when a large number of cars are to be shipped out at once, such as when they are loaded on a ship, this will be explained using FIG. The stacker crane 3 is running to a predetermined position in order to place it on the trolley 15, and at the No. 6 gate, it has already been placed on the trolley 15 and is changing direction. At the gate, car 16 was being carried out by the driver, and No.
At the 8th gate, the stacker crane 3 has just placed it on the trolley 15.

In this loading and unloading work, gates No. 5 and No. 6 and gates No. 7 and No. 8 share one stacker crane 3, so for example, when loading a car, , without proper instructions, there will be some waiting time. This waiting time adjustment is done in the second
As shown in Figure 6 or Figure 6, for example, if the number of gates is No. 1 to No. 12, the function of the stacker crane is checked by computer, and No. 1
~By skillfully combining confirmation and instructions to bring the car into the gate with the least waiting time among gates No. 12, it is possible to match the processing capacity in Hangar 1 with the delivery capacity on a 1:1 basis. It is.

In the case of carrying out work, smooth operation can be achieved by instructing the worker in advance which gate the vehicle to be carried out will exit from.

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) The car hangar is designed to store at right angles, and the trolley itself has a turntable function.
It is possible to lay a trolley rail corresponding to each row of storage shelves, allowing a sufficient distance between adjacent cars, and it is possible to install a trolley for loading and unloading on each storage shelf.

(b) In addition, since a trolley is provided corresponding to each hangar shelf, there is a good balance between the processing capacity inside the hangar and the processing capacity for carrying in and out, greatly improving the storage processing efficiency of the multi-level warehouse. Can be done.

(c) In addition, since loading and unloading operations are carried out independently, for example, even if one trolley breaks down, it will not affect the others at all, and furthermore, the distance between the loading and unloading section and the delivery origin is shortened. The installation area can also be reduced.

(d) In conjunction with the above-mentioned improvement in warehouse equipment efficiency, the traveling distance of the trolley is short, so the time required for loading and unloading is greatly shortened.

(e) Furthermore, collecting and collecting empty pallets at the unloading section, transferring these pallets to the loading section, and
It is no longer necessary to dismantle the accumulated pallets at the loading section and supply a loading line, resulting in a significant reduction in equipment.
Palette operation can be simplified.

(f) In this way, it solves the problem of contact between cars when entering and exiting the warehouse, improves the work efficiency of drivers, improves warehouse efficiency, shortens the time required for entering and exiting the warehouse, and reduces the site area. It has excellent effects as a three-dimensional warehouse.
