Description

TECHNICAL FIELD The present invention relates to a storage device for storing automobiles and other storage items in multiple stages, multiple rows, and multiple layers.

[Prior Art] Conventionally, in order to make effective use of a storage space of an automobile or the like as much as possible, as a storage device for storing stored items in multiple stages, as shown in FIG. 11 and FIG. In addition, an elevating space 2 for the stored items is provided through each stage from the ground to the uppermost stage, and on the left and right sides of the elevating space 2 for the stored items, a stored item loading pallet 4 capable of suspending and traversing the stored items 3 is stored. There were those in which the storage space 5 was arranged, a merry-go-round type storage device that circulates in a loop, and a puzzle type storage device.

[Problems to be solved by the invention]

In general, stored items are not always put in and out at fixed time intervals, but may be temporarily concentrated. However, in a storage device having an elevating space in the center, the stored items 3 must always pass through the elevating space 2 in the center when loading and unloading, and even a carousel of the merry-go-round type has a large number of storages on the narrow ground. Although possible, loading and unloading is done in one place.

Therefore, when it takes time to call an empty pallet at the time of warehousing and a target pallet at the time of warehousing, and when a large number of stored items are temporarily put in and out, the stored items are concentrated and crowded at the loading and unloading port on the ground, and stored. It interferes with work.

In addition, in both devices, it is difficult for a person to enter and leave the storage device when entering and exiting the storage device, but it is difficult to check that, and when a person is in the storage device, the pallet accidentally goes up and down or falls. There is a risk of

The present invention solves the above problems in a storage device, can eliminate congestion at the loading / unloading port during peak times, and can store efficiently, and a person can stand in the storage device. It is an object of the present invention to provide a safe multi-row multi-row multi-layer storage device that does not require entry.

[Means for solving problems]

The multi-stage multi-row multi-layer type storage device of the present invention is provided with a mounting device capable of traversing each row except for the top row with one row being a vacant space, and each row of the top row and each mounting of each row except the top row. A puzzle-type multi-stage multi-row storage device, in which a pallet and a fork-shaped pallet stand that can be engaged and disengaged, are suspended in the device, is arranged in multiple layers in the front-rear direction, and for each row or each layer on the ground. At the provided loading / unloading port, there is arranged a traveling carriage capable of transferring pallets to and from the fork-shaped pallet stand and traveling in each row or each layer.

[Action]

Generally, a multi-stage, multi-row storage device called a puzzle type excludes the uppermost stage in the height direction and the horizontal direction in the m-row configuration (

The same applies to the case of storage.

When such puzzle-type multi-stage multi-row storage devices are arranged in parallel in the front-rear direction in n layers to form an m-row n-layer structure, an arbitrary i
The stored goods of the pallet in the j-th row and the k-th layer are formed in the k-th layer by forming the ascending / descending space to lower the target pallet to the ground, and further, from the 1st layer to the (k-1) th layer. The pallet on the unloading path is traversed to secure a passage, and then a forklift or the like is used to carry in and out between the warehousing port and the pallet (when the stored product is a car, the warehousing / unloading is carried out. Then, it is performed as follows.

(A) When storing stored goods When the storage position of the i-th row, the j-th row, and the k-th layer is empty, the pallet corresponding to that position is placed on the traveling carriage on the ground and prepared at the entrance / exit. The stored items are loaded on this pallet. In the k-th layer, the mounting devices in the j-th column below the i-th stage are traversed to form a hoisting space, and the fork-shaped pallet stand is lowered to the ground. The position of the fork-shaped pallet table where the fork-shaped pallet table between the j-th row and the k-layer fork-shaped pallet table and the traveling vehicle at the entrance and exit of the j-th column is traversed to form a traveling space, and the traveling vehicle is lowered. Move to. When the fork-shaped pallet table is lifted, the pallet is transferred to the fork-shaped pallet table and lifted, and a predetermined i-th row j-th column k
It is stored in the storage space of the layer. If the next storage item arrives at the entrance / exit before the end of the above storage cycle at peak time,
Put it on a pallet on the traveling carriage in the other row and make it stand by,
Then, the warehousing operation is performed.

(B) When a stored item is unloaded If the storage positions of the i-th row, the j-th column, and the k-th layer in which the desired stored item is stored are designated, as in the case of storage, the j-th column, the k-th floor elevating space, and the j-th column. The traveling space is formed and the traveling carriage moves to the j-th row and the k-th layer, and the fork-shaped pallet stand at the i-th step, the j-th row, and the k-th layer descends on the traveling carriage, and travels on the pallet on which the stored items are placed. Transfer to a dolly. The traveling cart is moved to the loading / unloading port and the stored items are taken out from the pallet.
