Description

[Detailed description of the invention] [Industrial application field] This invention can be used to store cars and other items in multiple stages.

This invention relates to a three-dimensional storage device that stores in multiple rows.

[Conventional technology]

Conventionally, in order to solve parking difficulties in urban areas, multi-level parking systems that can accommodate a large number of cars per level area have been developed, such as vertical circulation storage systems called tower parking systems and horizontal elevating storage systems called puzzle parking systems. There was a storage device, etc.

[Problem that the invention seeks to solve]

Vertical circulation type storage devices can store a large number of items in a narrow space, but there is only one entrance and exit, and it takes time to retrieve the empty pallets when they come in and the target pallets when they go out. When a large number of vehicles are required to enter and exit the garage, vehicles concentrate at the entrance and exit, leading to congestion and long waiting times. Furthermore, since the storage cages are each suspended from the chain, the weight is large, the chain speed cannot be increased, and the cost is high.

On the other hand, for a 2-stage, 1-m-row horizontal elevating storage device, each row in the hall is left empty except for the top row (β-1), and any i
When taking out a car on a pallet in column J, if there are other pallets on the delivery route, the traversing cart carrying the pallet is moved sideways to form an empty space for delivery, and the target pallet is lowered to the ground. The system is configured so that the vehicle can be taken out of the warehouse (returning the procedure is the reverse procedure). This device has individual hoisting devices for lifting and lowering the pallets on all the traversing carts except the bottom tier and the pallets suspended on the top tier, so storage units with a large number of storage units have a common entrance/exit. However, a large number of hoisting devices are required, which increases costs. In particular, increasing the operating speed to speed up the loading/unloading cycle not only requires a large number of high-output drive devices, but also requires a steady rest for the stored items, which is uneconomical.

This invention solves the above-mentioned problems in parking devices, and reduces the time required for entering and leaving the parking lot to reduce congestion at the entry and exit gates. The purpose is to provide a three-dimensional storage device.

[Means for solving problems]

The storage device of the present invention having multi-stage and multi-row storage spaces includes:
A traversable valet mounting platform is installed on each stage except the lowest stage, and vertical support arms are pivotally pivoted to the sides of a horizontal frame equipped with rope sheaves to form a gate-shaped frame. A lift cage, which is provided with a claw at the lower end of the vertical support arm and engages with the edge of the pallet, is suspended from the top of the two-most storage space.

[Effect]

(A) When stocking, if the pallet in the storage space in any i-stage, j-column is empty,
Among the pallet mounting stands in the j column, all the pallet mounting stands except for the one in the i stage are moved sideways to form a space for raising and lowering the lifting cage. Then, the elevator cage is lowered and the claws of its vertical support arms are engaged with the pallets in row i and row j,
After the pallet loading platform is evacuated sideways, the elevator cage is lowered and the pallet is placed at the lowest level! 3! place When the stored items are placed on this pallet, the elevator cage is rolled up to the i stage,
Return the pallet loading platform that had been evacuated. After the claws of the elevator cage are released from the pallet and the pallet is placed on the pallet mounting base, the elevator cage is rolled up and storage is completed.

(B) When leaving the warehouse When the position of the 1st column 1 j column where the stored items to be dispensed are stored is specified, a lift space in the j column is created in the same way as when entering the warehouse, and the elevator cage is stored in the i column. After engaging the loaded pallet with the claws of the vertical support arm, it is lowered to the lowest level. The stored items are then removed from the pallet and shipped.

Depending on the time of day, when unloading continues, the empty pallet is rolled up and returned to its original position, but when restocking is expected, it can be left on the bottom shelf for restocking.

〔Example〕

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of a three-dimensional storage device that is an embodiment of the present invention. This device has one arbitrary stage.

m columns (β1m is a positive integer), but in this example, ff=5. m=4, that is, 5 stages.

It has a configuration having four rows of storage spaces 7.

Here, each stage except the bottom stage is equipped with a pallet 8 (m-1), that is, three pallet loading tables 9 that can be moved laterally.
are arranged, and a car 10 as a stored item is loaded on the pallet 8.

A lifting cage 11 is suspended above the storage space 7 at the top, and can be raised and lowered by a hoisting device 12.

FIGS. 2 and 3 show pallet 8. Pallet mounting stand9. FIG. 2 is an explanatory view showing the front and side surfaces of the elevator cage 11. FIG. The pallet 8 has a flat plate shape with concave edges 13 formed on both left and right ends, and a convex portion 14 on the lower surface for positioning and fixing on the valet mounting table 9. The pallet mounting stand 9 is a cart having wheels 15, has a recess 16 on the upper surface into which the convex part 14 of the pallet 8 is inserted, and can be moved laterally on a rail 17 by a drive device (not shown).

The lifting cage 11 has vertical support arms 2 at both ends 21 of a horizontal frame 20 equipped with a rope sheave 18 and guide rollers 19.
2 are pivotally connected to be rotatable laterally to form a gate frame.

At the lower end of the vertical support arm 22, a T-shaped claw 2 as shown in FIGS. 4 to 6 or an L-shaped claw 2 as shown in FIGS. 7 and 8 is provided.
3 is provided, and this claw 23 is attached to the edge 1 of the pallet 8.
It is possible to engage with 3.

24 is a lobe of the hoisting device 12.

Further, a supporting arm 25 equipped with a guide roller 19 is provided at the upper part to prevent the lifting cage 11 from swinging when going up and down. to guide you. Guide roller 19
However, the support arms 25 are placed above and below the support arms 25 because there is a running space 27 in the middle of the guide rail 26 through which the wheels 15 of the pallet mounting base 9 pass, so that the guide roller j9 can smoothly pass through this space. This is to do so.

A solenoid 28 is provided between the horizontal frame 20 and the upper end of the vertical support arm 22, and by energizing the solenoid 28, the vertical support arm 22 is rotated laterally, thereby releasing the bullet of the claw 23. 8 is engaged and disengaged.

When storing a car 10, if the storage space 7 in row i and row j is empty, all the pallet mounting racks 9 in row j except for the one in row i are moved side by side. This forms a space for raising and lowering the elevator cage 11. The elevator cage 11 is then lowered and the solenoid 28 is actuated to engage the pawl 23 with the edge 13 of the pallet 8. Therefore, after the pallet mounting table 9 is retracted laterally, the elevating cage 1 is lowered and the valet 8 is placed on the lowest stage. The car 10 is driven onto this pallet, the elevator cage 11 is hoisted up to the i stage, and the pallet mounting platform 9, which has been evacuated, is returned to its original position. In this state, the claw 23 is detached from the pallet 8, the pallet 8 is transferred to the pallet mounting table 9, and the elevator cage 11 is moved.
is rolled up and storage is completed. If there is a lift cage 11 in row J
If there is no pallet mounting platform 9 in the adjacent column N-1) or (j+1), a space for lifting and lowering the elevator cage 11 is formed by moving the pallet mounting platform 9 in the adjacent N-1) column or (j+1) column horizontally. After moving it, it is raised and lowered in the same way to store it.

When leaving the car 10, if the position of the i stage and the j column where the car 10 to be taken out is stored is specified, a space for lifting in the j column is formed in the same way as when the car 10 is stored, and the elevator cage 11 is moved to the i position. After the pallet 8 loaded with the automobile 10 is engaged with the pawl 23 at the stage, it is lowered to the lowest stage. A car 10 is driven by itself from above a pallet 8 placed on the lowest stage to leave the warehouse. If there is a new car 10 in the empty valet 8,
It can be used as is for stocking. If the item continues to be delivered, roll it up and return it to its original position. This storage device differs from conventional traversing lift types in that it does not have a traversing trolley at the bottom, and the entry/exit entrance is not limited to one location, allowing for independent entry/exit processing. Even when multiple vehicles need to be loaded and unloaded, multiple vehicles can be processed at the same time, reducing congestion and waiting times caused by cars concentrating at the loading/unloading gate. In addition, the parts at the bottom where lifting is not performed (the left and rightmost rows in Figure 1) are as follows:
During busy times, it can be used as a path for cars to enter and exit, and as a waiting space, and during off-hours, it can be used as a flat parking floor.

〔Effect of the invention〕

The three-dimensional storage device of the present invention is configured as described above,
Since there is no need to provide a hoisting device for each traversing truck, the number of hoisting devices can be reduced, equipment costs can be reduced, and it is easy to increase the height of the elevator cage by increasing the speed. In addition, congestion at the time of entering and exiting the warehouse can be prevented, and a large storage device with a large storage capacity can be used.

In addition, compared to the case where the cage has a rigid frame structure and a complicated gripping device is installed at the tip, the bending moment acting on the cage can be reduced and the weight can be reduced, and the structure is simple and the engagement with the pallet can be performed safely and reliably. .
