JPH04260514A - Three-dimensional warehouse for heavy article of traveling cart type - Google Patents

Abstract

PURPOSE:To enable storage of heavy articles, free carry-in and carry-out, and wasteless storage of articles by assembling a support structure material in the directions of side, depth, and height at the predetermined space in a matrix shape, and providing many pairs of rails, many carts, a drive vehicle, and an elevator for loading article on the support material in lateral direction. CONSTITUTION:To lower a loading article 9' on the floor at the lowest floor, a cart 5 for each floor on the loading article 9' is moved to ensure a lift-up passage, and the cart 5 is moved and removed from the passage to ensure the passage. Next, as for the direction of travel of the cart 5, the cart 5 on the right side is moved to the left and connected with the intermediate cart 5 by means of a connecting tool 7' in the case of the uppermost floor. Then, a connecting tool 7'' of the intermediate cart 5 is removed to separate the cart 5 on the left side, and two carts 5 are moved to the right. Also, the cart 5 is moved in the same way in the case of the second and third floors. Upon completion of the travel of the carts 5, a lift 8 for loading article is positioned on the lift-up passage, and its hook is lowered and hooked on the loading article 9' to lift it up.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile trolley-type multi-story warehouse for heavy goods, which uses a mobile trolley and a hoist-type overhead crane to easily take in and take out heavy goods.

0002

2. Description of the Related Art Three-dimensional warehouses have been used for storing articles. This method employs a method of loading and unloading stored items from the side of a multi-level warehouse using a forklift. FIG. 6 is an explanatory diagram of the loading and unloading operation of loaded items in a conventional warehouse.

0003

The conventional system uses a forklift for loading and unloading from the side, which limits the weight of the articles that can be handled, making it difficult to handle heavy items. Also, space was needed for a forklift path. Furthermore, space was required to store the forklift. These spaces have become a limiting condition for storing goods.

The object of the present invention is to solve the various problems described above, and to provide a mobile trolley type solid body for heavy objects, which is capable of storing heavy objects, can be taken in and taken out freely, and can store objects without waste. It is to provide a warehouse. It also aims to provide the above-mentioned multi-level warehouse at a low cost.

[0005]

[Means for Solving the Problems] The apparatus according to the present invention is a mobile trolley-type multi-level warehouse for heavy goods as described below. That is, it consists of a three-dimensional structure constructed by assembling supporting structural members in a matrix shape at predetermined intervals in the lateral, depth, and height directions; A large number of pairs of rails are arranged on the rail; a large number of carts are arranged on the large number of pairs of rails; a coupling device for connecting the large number of carts is provided at the front and rear of the large number of carts; be equipped with a drive car for moving the bogies on the rails for each row of the large number of bogies; for each row of bogies, the total number of bogies and drive cars is equal to the space of the bogies; be smaller than the total number of; be equipped with a load lifting device for loading loads onto and unloading loads from the truck; moving the load lift device back and forth and from side to side. The ceiling is provided with a track for a loaded load lifting device for the purpose of This is a mobile trolley-type multi-storey warehouse for heavy goods, characterized in that the space between the supporting structures in the depth direction is sufficiently larger than the lateral dimension of the cargo loaded on the trolley.

[0006] In the above-mentioned mobile trolley-type multi-level warehouse for heavy goods, it is possible to use a hoist-type overhead traveling crane as the load lifting device.

[0007] Furthermore, it is also possible to equip an overhead traveling automated guided vehicle equipped with a hoist as the load lifting device, and to also provide means for remotely operating this.

Furthermore, in the above-mentioned mobile trolley-type multi-level warehouse for heavy goods, it is also possible to equip the area around the load lifting device with a guide tool for smoothly moving the load up and down.

[0009] Furthermore, the above-mentioned equipment may be provided with means for remotely operating a drive vehicle for moving the trolley on the rails.

0010

[Example] In Figures 1 and 2, 1 is a column, 2 is a beam in the depth direction, and 3 is a beam in the horizontal direction.These supporting structural members are assembled in a matrix as a whole, and Construct a support structure that forms a number of spaces for housing the trolley.

A large number of pairs of rails 4 are laid horizontally on the horizontal beams 3 of each floor except the lowest floor. On each pair of rails 4, a plurality of carts 5 and one drive car 6 are arranged in a row. These rows of carts 5 are designed to be movable along the rails 4 by drive cars 6. multiple trolleys 5
One unit is accommodated in each space. The total number of the plurality of carts 5 and the driving cars 6 is the number of spaces (
In this embodiment, the number of carts 5 is 3 and the number of driving cars 6 is 1, which is one less than the number of vehicles (in this embodiment, 5 rooms). Each truck 5 and drive vehicle 6 are connected to each other by a connector 7. The drive wheel 6 and the connector 7 are manufactured to be operated by remote control.

Reference numeral 8 denotes a load elevating device for loading and unloading the load 9 onto the cart 5. Examples of the load lifting device 8 include a hoist overhead traveling crane and an overhead traveling automated guided vehicle equipped with a hoist. The loaded object lifting device 8 moves back and forth and left and right along a loaded object lifting device track 10 provided on the ceiling. The load lifting device 8 is operated by remote control. A guiding tool (not shown) is installed around the loaded object lifting device 8 to smoothly move the loaded object up and down.

Next, a description will be given of the loading and unloading operation of the loaded object using the apparatus of the above embodiment. In FIGS. 3 and 4, in order to unload the loaded object 9' placed on the floor of the lowest floor, first move the trolley 5 on each floor above the loaded object 9' to secure a lifting passage. I'll keep it. In order to secure this passage, the cart 5 is moved and removed from the passage. For example, in the case of the top floor, the method of moving the trolley 5 is as follows.
As shown in FIG. 5, first, the right hand truck 5 is moved to the left and connected to the middle cart 5 by the connector 7'. Subsequently, as shown by the imaginary line, the connector 7'' of the middle cart 5 is removed to separate the left cart 5, and the two carts 5 are moved to the right to be in the state shown in FIG. The cart 5 is moved in the same manner on the second and third floors.

When the movement of the truck 5 is completed, the loaded object lifting device 8 is positioned on the lifting path, and its hook is lowered to hook onto the loaded object 9' and pulled up.

[0015]

[Effects of the Invention] The mobile trolley-type multi-level warehouse for heavy goods of the present invention is capable of storing heavy goods, and can freely take them in and out.
Moreover, it is possible to store items without waste.
