Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a building having a plurality of floors,
For example, the present invention relates to a device for vertically transporting a load from a floor entering and leaving a warehouse to a floor of another floor in a warehouse having floors of several floors.

[0002]

2. Description of the Related Art Transported goods (luggage) in a warehouse consisting of multiple floors
A forklift, a roll box (pallet with wheels) or a small transport vehicle is used to carry the goods into the elevator, and the goods carried by these are carried into the elevator and moved to the floor of the specified floor by this elevator. Then, on the floor, it is taken out from the inside of the elevator by using the carrying device such as the forklift and carried out to a predetermined place.

[0003]

In the case of an elevator installed in a large-scale building or hotel, the floor surface of each floor and the elevator floor surface are stopped so that they coincide with each other, and Regardless, it stops at a predetermined position. However, in the case of an elevator for luggage, it is not a device that accurately estimates the safety factor to a large extent, and a slight step is generated between the floor surface of each floor and the elevator floor surface. This step will change depending on the amount of luggage loaded in the elevator.

When loading and unloading luggage in the elevator by a forklift traveling on the floor of each floor,
The height of the forks can be adjusted and plugged into the elevator, so the work is not impossible. However, in the case of a small hand-held transport vehicle, it has to enter the elevator floor surface from the floor surface and then exit, so even if there is a slight step between the floor surfaces, this transport vehicle can enter the elevator surface.・ If you cannot move out and the load is heavy, several people will operate one transport vehicle. Further, when using a pallet with wheels, that is, a roll box, there is a problem that it is difficult to enter the elevator due to the step difference as described above.

A license is required to carry a transported object by using a forklift, and therefore, it is not possible to carry the transported object without the specific operator.
As a practical matter, it is difficult to prepare such workers at each warehouse or factory. In addition, when using a forklift, it is necessary to secure a passage through which it can be moved, especially a plaza in front of the elevator so that the forklift can turn around, which is wasteful in space and is not used in small warehouses. Can not do it.

[0006] The present invention has been achieved to solve the problems of the above conventional elevators, in which a load placed on the floor can be easily carried into the elevator, and (EN) A vertical transfer device that can be carried out from the inside of an elevator to the floor surface of another floor.

[0007]

In order to achieve the above object, a vertical carrying apparatus according to the present invention supports a load receiving frame in a vertical frame body so as to be able to move up and down, and can move in and out horizontally with respect to the load receiving frame. It is configured by providing a fork device. A fork device supports the load receiving frame so as to be vertically adjustable.

More specifically, a load receiving frame 4 is supported in a vertical frame 2 so as to be able to move up and down, and the loading / unloading claw frame 6 is moved up and down with respect to the load receiving frame 4 by a drive device 9. The claw-shaped arm 7 is supported so as to be adjustable, and a claw-shaped arm 7 is provided to the loading / unloading claw frame 6 so as to be able to move in and out in a horizontal direction by a driving device. The claw-shaped arm 7 supports a load and carries it into the load receiving frame 4. Alternatively, it is configured to be carried out from the inside of the receiving frame 4.

[0009]

[Operation] Since the fork device is installed in the cargo receiving frame, that is, the elevator lifting frame, carry goods into the elevator from the floor, or carry goods stored in the elevator to the floor. It is possible to carry out the carrying-out operation very easily, and it is possible to carry out operations such as carrying goods in a factory and carrying goods in a warehouse safely and quickly.
