Description

[Detailed Description of the Invention] Industrial field of application The present invention is applicable to automobiles such as parking devices and automatic warehouses, cargo, etc.
The present invention relates to an automatic storage device and method capable of automatically storing vehicles (hereinafter simply referred to as automobiles, etc.).

In the conventional parking device, for example, an endless chain is hung between sprockets arranged above and below inside the tower, and cages suspended from the chain at equal intervals are circulated by the rotation of the sprockets, and cars entering the cage are sequentially moved to the tower. Vertical circulation system that stores indoors in the air, parking spaces are provided in multiple stages on the front and back or left and right sides of the car elevator, and cars that are transported to the desired floor by the car elevator are parked by self-propulsion or by a horizontal conveyance device. An elevator system in which cars are moved into a space for storage, and an elevator slide system in which a car elevator moves horizontally as it goes up and down, and multi-level parking spaces are installed parallel to both sides of the elevator travel path. In addition, there are various types of parking spaces, such as multi-level parking spaces, and each level has multiple unit boards that can move horizontally and move up and down above the parking space. A car elevator is installed, and the pallet carrying the car is grabbed by the car elevator through the lifting space formed above and below by moving the unit plate of each stage, carried to the desired floor, and is received by the unit plate from below and stored. There is also a type that does this (Japanese Patent Application No. 62-29145).

Problems to be Solved by the Invention The latter type shown in Japanese Patent Application No. 62-29145 is capable of storing multiple rows or rows of vehicles on each stage by horizontally moving an automobile elevator from side to side or back and forth. (by moving the car elevator from side to side and back and forth, cars can be stored in multiple rows and rows on each level). Since you only need to move the unit plates, the power required for loading and unloading can be reduced, and since each unit plate has a small mass, the influence of inertia can be reduced, making control easier. However, in order to be able to store a large number of cars on each tier, it is necessary to be able to move the car elevator to the left and right or at least front and back. In such cases, when entering or exiting a warehouse, a car must be transported to the top level using an elevator, then moved horizontally and descended.

Conventional devices, including the type shown in the latter Japanese Patent Application No. 62-29145, have also been used to transport automobiles, etc., unless a plurality of automobile elevators are provided or a plurality of automobiles, etc. can be transported side by side. As a general rule, not only can only one vehicle be taken in and out of the warehouse, but it is also not possible to take out the warehouse until the entry is completed, and it is not possible to enter the warehouse until the delivery is completed, and it is not possible to take in and out at the same time.
Further, it is not possible to carry out the next warehousing or warehousing.

In the conventional system, storage spaces are provided on both sides of the lifting space where the car elevator goes up and down, and the car is sent into the storage space by a transport device. The transport devices are each driven independently, and each transport device has a drive device such as a motor, making the structure of the device complicated.

The present invention is an automatic storage device in which storage spaces are provided on both sides of an elevator space, so that even cars located at the back side that do not face the elevator space can be put in and taken out without having to lift the elevator to the top level. Aiming at speeding up, another invention is to make it possible to take out or put in a plurality of cars at once, or to take out and put in a warehouse at the same time, using the elevator used in the above invention. With the goal.

Yet another object of the invention is to enable vehicles, etc. to be taken in and taken out of the warehouse at the same time, and to make it possible to carry out the next entry and exit without completing the entry and exit, thereby speeding up the delivery and removal. shall be.

Yet another object of the invention is to further speed up the loading and unloading process by combining the above-mentioned inventions.

Another object of the invention is to simplify the structure of the apparatus by using a common drive source for each conveyance apparatus.

Means for Solving the Problems In order to achieve the object of the first invention, there is provided an elevator that moves up and down a lifting space to transport cars, etc., and an automatic storage device that has storage spaces arranged in multiple stages on both sides of the lifting space to store cars, etc. In the elevator, the elevator is configured to have a plurality of upper and lower stages, and each stage can accommodate a vehicle, etc., and a transport device for horizontally moving the vehicle, etc. is provided in each stage of the elevator and each storage space.

The storage space may be elongated so as to be in series with the elevating space, or the elevating space may be elongated in the front and rear or left and right directions and provided in parallel along the elongated elevating space. In the latter two cases, the elevator is horizontally movable back and forth or left and right, or multiple elevators are installed so that each elevator can go up and down independently, or the length is the same as the elevator space. It is constructed so that multiple cars etc. can be transported at the same time.

A typical example of the transport device is a conveyor.

The transport device installed in the storage space may be a plurality of devices arranged in series so that cars, etc. can be transferred, or it may be a single device, which allows multiple cars, etc. to move horizontally. . Note that the conveyance device of the elevator may be the same type as the conveyance device of the storage space, or may be different.

In order to use the above-mentioned elevator to move multiple cars in and out at once, a recess into which the elevator enters is formed in the first floor, and by raising and lowering the elevator, each stage is brought to the level of the first floor. According to the method of loading and unloading cars, etc., installing a floor with a difference in height at the entrance of the first or several stages depending on the number of stages of the elevator, and creating a passageway that reaches each floor, and floors with different heights from the left and right of the elevator. There are methods for moving cars etc. in and out.

Another device that can speed up the loading and unloading of cars, etc. includes an elevator that moves up and down the lifting space and transports cars, etc., and a storage space that is arranged in multiple stages on both sides of the lifting space to store cars, etc. An automatic storage device that has an automatic storage device that can be raised and lowered adjacent to the lifting space, and that can be moved horizontally with a lifter that can lift a car, etc. from the first stage to the upper stage, and that is The elevator, the lifter, and the cart are each provided with a transport device for horizontally moving an automobile or the like.

Here, the storage space may be formed in series or in parallel with the elevating space, or may be formed to be wide in the front-back and left-right directions, as described above. If the elevators are arranged in parallel along the elevating space or are formed wide on the left and right sides, the elevators can be moved back and forth or left and right, or multiple elevators are provided so that they can each move independently, or the elevators are arranged so that they can move independently. formed to the same length.

The first floor in the method and apparatus described above may be flush with the ground, or may be higher or lower than the ground.

Although the trolley may be movable in a direction perpendicular to the storage space, it is preferably movable in a direction along the storage space below the storage space. In the former case, the conveyance device installed in the elevator needs to be able to move forward and backward as well as in the left and right directions, making the structure of the conveyance device complicated, whereas in the latter case, the conveyance device of the elevator must be able to move forward and backward or left and right. This is because it is only necessary to allow movement in one direction, which simplifies the structure.

The lifter may be of any type as long as it has the function of lifting an automobile or the like, and examples of such a lifter include a lifting type and a bending/stretching mechanism that combines a buntograph mechanism and a hydraulic cylinder.

Examples of the switching device include a hydraulic cylinder connected to a truck to move the truck forward and backward, a self-propelled device for the truck including a motor, and the like.

As the conveyance device, a conveyance device similar to that used in the first invention is used, and a device suitable for conveying an automobile or the like, such as a pallet 7), is used as necessary.

In another aspect of the above-described apparatus, a conveying device for horizontally moving an automobile or the like is provided on the opposite side of the raised lifter across the lifting space. In this case, the trolley of the device described above can be omitted.

Another method that can speed up the loading and unloading of cars, etc. uses the above-mentioned device in which cars, etc. are placed on pallets and moved horizontally, and is placed in series with a trolley across the lifting space. Empty pallets are placed on the provided conveyance device, and when a car etc. enters the warehouse, they are moved horizontally and replaced with the pallet that carries the car etc. lifted by the lifter, and when the car leaves the warehouse, it is replaced with the pallet that carries the car etc. that has been lowered into the elevator. be replaced.

Yet another method for further speeding up the loading and unloading of automobiles, etc. is that in the above method, the elevator used is comprised of a plurality of upper and lower stages, so that automobiles, etc. can be stored in each stage.

In order to simplify the structure of the conveyance device by sharing the drive source of the conveyance devices installed in elevators and storage spaces, etc., we have created an elevating space where the elevator goes up and down, a storage space located on both sides of the elevator, and a storage space located on both sides of the elevator and the elevating space. It consists of an elevator and a transport device installed in a storage space,
In an automatic storage device in which automobiles and the like are transported from an elevator to a storage space by a transport device, each transport device is composed of an endless conveyor, and the transport device installed in the elevator is provided with a drive source consisting of a motor, and the storage space is A clutch mechanism is provided for intermittent transmission of power to the conveying device.

The automatic storage device referred to here may be one based on the conventional elevator system or elevator slide system mentioned above, or one of the type shown in Japanese Patent Application No. 62-29145, or one that partitions an elevator into multiple upper and lower stages. Or,
The above-mentioned device may include a horizontally moving cart.

The conveyor may be one wide conveyor, or it may be multiple narrow conveyors, and vehicles etc. may be placed directly on it, or conveyors may be placed on it via pallets. You may also be able to post it.

The clutch mechanism is provided with a transmission mechanism to ensure that the conveyance device of the elevator and the conveyance device of the storage space are fed in the same direction. This transmission mechanism may be a friction transmission or a gear transmission.

In the case of friction transmission, a friction wheel that rotates in conjunction with a motor engages directly with the conveyor or with a friction wheel that is coaxial with a pulley or sprocket on which the conveyor is installed, and in the case of gear transmission, a friction wheel that rotates in conjunction with a motor engages with a friction wheel that is coaxial with the pulley or sprocket on which the conveyor is installed. The gear that engages with the gear that is coaxial with the pulley or sprocket.

As for the conveyance device, one similar to the above-mentioned conveyance device is used.

Operation Figures 4A to 4E show an example in which the elevator l is arranged in two stages, upper and lower, so that cars, etc. can be stored in each stage.When leaving the car, etc. 4 in the storage space A, After adjusting the level of the transport device 2A to the transport device 3 in the storage space (Fig. 4B),
Vehicles 4.5 in storage spaces A and B are both transported by the transport device 3, and first, the vehicle 5 is stored in the upper tier of the elevator 1 (Fig. 4C).Next, the elevator 1 rises by a certain amount and moves to the lower tier. The transport device 2B matches the level of the transport device 3 (Fig. 4D), and the automobile etc. 4 is stored in the lower stage of the elevator l (Fig. 4E), and then the elevator 1 is fixed! After descending, the upper transport device 2A matches the level of the transport device 3, and the upper transport device 5 is sent into the transport device 3. Thereafter, the elevator 1 containing the cars 4 descends.

Note that the movement of the elevator 1 may be reversed so that the automobiles etc. 5 in the storage space B can be stored in the lower tier and the automobiles etc. 4 in the storage space A can be stored in the upper tier.

When a car or the like is stored in the storage space A, the car or the like in the storage space is put into the -l elevator and operated according to the procedure described above.

When leaving the storage spaces A and B together, the elevator l descends to the lowest position of the first stage and enters the recess 6 of the floor 7, and the cars on the upper stage first (Fig. 5A), then the elevator 1 rises by a certain amount, and the cars in the lower tier are taken out of the garage in sequence (Fig. 5B).Conversely, it is also possible to have the cars in the lower tier be taken out first, then the cars in the upper tier.

The same procedure as above is followed when warehousing.

As shown in Fig. 6, if there is a height difference in the floor 8 and a passageway is provided to reach it, cars etc. stored in the upper tier of the elevator 1 will be placed on the lower floor than cars etc. stored on the lower tier. The goods will be delivered from each floor. When entering the warehouse, the items are stored in the upper and lower tiers of the elevator l via each aisle and each floor.

Figures 7A to 7H show a horizontal conveying device 10 that is adjacent to the lift space of the elevator and can be lifted by a lifter from the first stage, and that is moved horizontally to a position on the lifter's lift path and a position retreating from it. This figure shows the procedure for loading and unloading a mechanism that has a trolley 11 with a transfer device that can be switched to and from the warehouse.After the trolley 11 has moved to the retreat position (Fig. 7B), the elevator 12 containing the vehicle 13 to be exited is shown. is lowered onto the transport device 14, and the vehicle 15 to enter the warehouse is placed on the transport device 10, and lifted by the lifter 9 to the level of the trolley 11 and the transport device 14 (Fig. 7C). and 15 are both horizontally moved to the left by each conveyance device and transferred onto the adjacent conveyance device (Fig. 7D), and then the vehicle 13 placed on the conveyance device 10 to be left is lowered by a lifter ( (Fig. 7E), the trolley 11 moves to the right onto the lifting path of the lifter (Fig. 7F), and the vehicle 15 on the trolley
is sent to the conveyance device 14 (Fig. 7G), and then the automobile etc. 15 is transported by the elevator 12 (Fig. 7H) and stored in the intended storage space.

When a conveyance device is provided on the opposite side of the lifter across the lifting space, vehicles entering and leaving the warehouse are horizontally moved to the right, and conversely, vehicles leaving the warehouse are temporarily retreated to the right. Then, the cars and the like to be stored are carried upwards by the elevator, and then the cars and the like that have been evacuated are moved onto the lifter and taken out.

Figures 8A to 8G show another procedure for the warehousing method using pallets using the above device.
As shown in the figure, an empty pallet 18 placed on a conveying device 17 which is provided in series with the truck across a lifting space is transferred to the conveying device and sent onto the truck (FIG. 8B), and the pallet 18 The cart 11 carrying the pallet moves to the left retreat position (FIG. 8C). Next, the elevator 12 lowers the empty pallet 19 onto the conveyor 14, and the lifter 9 lowers the automobile, etc. placed on the pallet 20. 1

(Fig. 8D), then move horizontally together with other pallets 18 and 19 and transfer to the next conveying device (Fig. 8D).
Figure E).

Thereafter, the car etc. 13 is transported to the upper floor by the elevator 12, and the empty pallet 18 is lowered (Fig. 8F).
, the cart 11 is moved to its original position (FIG. 8G), and an empty pallet is lowered to the first stage to replace the vehicle, etc. to be parked, and then the vehicle, etc. to be parked is placed thereon.

Figures 9A to 9G show the procedure for exiting the warehouse.
First, the trolley 11 moves backward to the left in the same manner (Fig. 9B),
An elevator 12 places a car or the like 15 on a pallet 19 and lowers it onto the conveyor 14, and an empty pallet 20 is lifted by a lifter 9 (9th
Figure C) Next, the pallet 19 carrying the automobile etc. 15 is sequentially moved horizontally to the left along with the other pallets 18 and 20,
After that, the automobile etc. 15 is lowered by a lifter, and the elevator carries the empty pallets 8 to the upper floor (Fig. 9E) and places them in the desired storage space. Or they are accumulated at a predetermined location. From then on, the trolley 11 moves to the right in the same way as above (Fig. 9F).
The pallet 20 is transferred to the transport device 17 (Figure 9G)
.

Although the procedures for warehousing and unloading have been described above, it is also possible to perform warehousing and unloading at the same time using the same procedure.

As described above, empty pallets are now supplied to the first floor as they are loaded and unloaded, compared to the conventional method where empty pallets are supplied to the first floor for loading and unloading after completing loading and unloading. The speed of pallet supply is increased, and warehouse loading and unloading can be done quickly.

When an elevator is provided with a conveyance device having a driving source consisting of a motor and is also provided with a transmission mechanism, by engaging the transmission device with the conveyance device of the storage space, both the conveyance device of the elevator and the conveyance device of the storage space are driven by the motor. is driven by the driving source.
