Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an automatic storage shelf, and more particularly, to an automatic storage shelf that automates the operation of storing and taking out objects to be stored such as various rolls, various products, steel materials, pipes, and the like.

[0002]

[Prior art]

 The following are known as means for storing objects to be stored in and out freely.

[0003] (A) Means for loading and unloading objects to and from a three-dimensional warehouse by a stacker crane

(B) Means for loading / unloading objects to / from a fixed shelf with a forklift truck

(C) Means for loading and unloading objects to and from a stepladder-shaped inclined shelf by an overhead crane

(D) Means for stacking objects to be stored on the floor, and for stacking and removing the objects to be stored are performed by an overhead crane.

[0007]

[Problems to be solved by the invention]

 However, the means (a) to (d) have the following problems.

[Means (A)] Since a stacker crane is expensive, it cannot be profitable unless it is a large-scale warehouse. Stacker cranes are suitable for luggage stored in containers, but are not suitable for items not stored in containers.

[Means (b)] Since a forklift vehicle turns, a large space is required around the fixed shelf and the passage of the forklift vehicle in order for the forklift truck to move the stored objects in and out of the fixed shelf. I need. In addition, when the object to be stored is loaded on the forklift vehicle, if the center of gravity of the object to be stored is not properly adjusted to the position of the fork in the forklift vehicle, the object may fall from the forklift vehicle during traveling.

[0010] [Means (c)] The object placed on the uppermost stage of the inclined shelf can be easily lifted by the overhead crane, but the object placed on the lower stage is lifted by the overhead crane. It's difficult to do it. If the inclination of the inclined shelf is reduced, the work to be lifted by the overhead crane can be easily carried out by using the overhead crane, but in this case, the floor area occupied by the inclined shelf increases.

[Means (d)] When removing the lower layer of the stored items stacked on the floor, the upper layer of the stored item is first removed by the overhead crane, and then the desired stored item is removed. It is necessary to hang out the garbage and then stack the removed objects back to their original positions. This is a cumbersome and inefficient task. In addition, the places where goods are stored tend to become more and more messy over time.

The present invention has been made to solve the above-mentioned problems in the conventional means (a) to (d). That is, the present invention has been made to provide an automatic storage shelf having a small occupied floor area, in which various objects to be stored can be easily stored in a sorted state.

 [Automatic Storage Shelf of Claim 1] The storage objects are stored in each storage object support shelf of the storage device in a state where they are appropriately classified according to the size, shape, material, and the like. The items to be stored may be placed directly on each of the items-supported shelves, but it is preferable that the items to be stored are appropriately stored in containers such as pallets and placed on the respective items-supported shelves. Since the storage shelves are arranged vertically, the floor area occupied by the storage device is small.

The storage object is put in and taken out of the storage object support shelf from the opening side opposite to the input / output device by the input / output device.

The loading / unloading device operates on the rail by rotating the wheels by operating the first driving means, and approaches the storage device or moves away from the storage device. The fork of the access device is moved up and down (moves up and down) by the second driving means. The fork is moved in and out by the third driving means (projects from or retracts into and out of the access device).

For example, a case of taking out a desired storage object (the storage object indicated by reference numeral 1b with hatching) stored in the storage device will be described with reference to FIGS. First, a pair of floor mounts (see reference numeral 3) are previously arranged on the floor on both sides of the rail. By moving the loading / unloading device on the rails, it is stopped in a state of approaching the storage device (see FIG. 5), and the fork is raised to a position directly below the storage object support shelf on which the desired storage object is placed. At the same time, the fork is made to protrude below the storage object support shelf (see FIG. 6). In this state, the fork is further raised to place a desired object on the fork (see FIG. 7). Subsequently, the loading / unloading device is moved in a direction away from the storage device to stop near the floor table, the fork is lowered, and the object to be stored on the fork is placed on the floor table (see FIG. 8). ). Thereafter, the fork is immersed in the device, and the fork is raised to the home position. Further, the loading / unloading device is moved in the direction of the storage device, and the object to be stored on the floor table is lifted by, for example, a crane (see FIG. 9). In addition, when storing an object placed on the floor table in the storage device, the above procedure may be performed in reverse.

In the automatic storage shelf according to the second aspect, the fork of the loading / unloading device in the automatic storage shelf according to the second aspect is rotated in a predetermined horizontal direction so as to protrude below the storage object support shelf and move in the opposite horizontal direction. It is immersed in the device by rotating.

[Automatic storage shelf of claim 3] In the automatic storage shelf of claim 3, when the access device approaches the storage device, the base provided with wheels in the access device enters the opening of the storage device base. Thus, when the automatic storage shelf is not used, the loading / unloading device can be compactly fitted into the storage device, and the floor area occupied by the automatic storage shelf can be reduced.

In the automatic storage shelf according to the fourth aspect, the auxiliary wheels of the storage device are supported by the receiving plate of the storage device when the storage device is approached to the storage device. The loading / unloading device is guided and supported by the storage device, and especially in the case of a large automatic storage shelf, the loading / unloading device is stabilized.
