DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically movable shelf member raising and lowering device used in a general stock shelf, a tableware disinfection storage room storing a large amount of tableware, a cold storage room, and the like.

[0002]

2. Description of the Related Art For example, in a tableware disinfection storage using this type of shelf member elevating device, the storage position of the storage is determined by the worker's good working posture and the height of the mounting table, etc. For example, the position of the third stage is usually used.
For this reason, when storing items, first, the uppermost shelf member stacked at the bottom is raised to the third stage position, the stored items are placed on the uppermost shelf member, and then the second The shelves are sequentially stored from the upper shelf so that the shelves are lifted to the third-stage position to place the stored items.

[0003] Therefore, when the stored items are placed in the upper three stages and then stored in the lower two stages, the hanging member, that is, the shelf member cannot be lifted any more, and the worker bends his waist and cannot be forced to do so. I have to put the stored items in the lower two stages in the posture,
In the case of heavy storage items, it is not particularly easy to put in and out.

[0004] For this reason, Japanese Patent Laid-Open Publication No.
In the publication, a plurality of shelf members are divided into an upper shelf group and a lower shelf group, and the upper shelf group and the lower shelf group are individually lifted and lowered, so that the lower shelf group can be raised and lowered to a position above the access position. Has been proposed.

[0005]

However, in this shelf device, all the upper and lower members of the lower shelf group are connected by pillars, and the lower shelf group is suspended by wires for the lower shelf and integrally moved up and down. For example, in a case where it is desired to lower all the shelf members to create a sufficient space above by lowering all the shelf members in order to store large storage items, the lower shelf group is not stacked and desired. There was a problem that space could not be obtained.

Further, a shelf moving device installed on the upper part for driving the shelf member up and down is constituted by a pair of endless chains arranged horizontally, and a wire for hanging each shelf is connected to the chain. Due to the structure, the horizontal width of the main body frame has to be increased to some extent, and there is a problem that a vertically long shelf device with a small installation area cannot be manufactured.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can easily store and remove stored items in a comfortable posture, and can sufficiently create an upper space. An object of the present invention is to provide a shelf member lifting / lowering device which can be formed vertically and can reduce an installation area.

For this purpose, a shelf member lifting apparatus according to the present invention has a plurality of shelf members horizontally supported in a shelf frame so as to be able to move up and down by hanging members suspended from above. In a shelf member elevating device provided with a hoisting device for winding up the suspending device, all the shelf members arranged in the shelf frame are sequentially suspended by the suspending device, and the auxiliary suspending device is connected to the shelf member at the intermediate position, A hoisting device and an auxiliary hoisting device are provided on the shelf frame, a hoisting device is wound up by the hoisting device, and the auxiliary hoisting device is connected so as to be hoisted by the auxiliary hoisting device.

[0009]

For example, six shelves (six shelves) are arranged in a shelf frame, auxiliary hanging members are connected to the third shelves, and the position of the entrance of the stored goods is determined by the good workability. From the third row of the shelf.

[0010] When all the shelves are empty and the stored goods are to be put in first, the auxiliary winding device is first driven to raise the third and lower shelf members, and the lowermost shelf member is moved to the third shelf member. (Entrance). Then, after placing the stored items on the lowermost shelf member, the auxiliary winding device is driven to lower the lower shelf member by one step, and the second lower shelf member is positioned at the entrance. And put the items on it.

Next, the auxiliary hoisting device is driven to lower the lower shelf member one step further downward, and the upper shelf member (the shelf supported by the hanging member) stacked on the third shelf member from the bottom. ) Is positioned at the doorway, and the articles are placed on the uppermost shelf member.

Next, the main hoisting device is driven to raise the suspension by one step (the uppermost shelf member is lifted by one step), and the articles are placed on the second shelf member.

[0013] Then, the hoisting device is driven to further raise the suspender by one step (the top and second shelf members are lifted by one step), and the articles are placed on the third shelf member. Next, the hoisting device is driven to further raise the suspender by one step, and the uppermost, second and third shelf members are lifted by one step. As a result, a space is formed on the lower shelf member, that is, on the third shelf member from the bottom, and finally, the stored items are placed on the shelf member, and a full storage state is obtained.

When taking out the stored items, the same operation is performed in the same manner as the above-mentioned operation, and the stored items are sequentially taken out from the shelf members.
