When cargo c is carried into elevator cage d, pushed into elevator cage d one after another, and the required cargo is loaded, staff e of elevator a operates elevator a to move it to the required floor.
When the target floor is reached, the worker f on that floor
There is a method of sequentially pulling out the cargo placed on wagon b in elevator cage d, but all of this is done manually.

Therefore, in recent years, in order to reduce the amount of manual work and save labor, a tray conveyor g that can be reversibly reversible has been fixed inside the elevator cage d from the doorway of the elevator cage d toward the back, as shown in Figure 7. However, forklift i is used to transport cargo. In this case, driver h is forklift i
When the cargo is transported to the elevator cage d and loaded onto the tray conveyor g, the attendant e of the elevator a operates the tray conveyor g in normal rotation to sequentially move the cargo to the back of the elevator cage d.
When the required cargo is loaded, the attendant e operates the elevator a to move it to the required floor, and when it reaches the destination floor and stops, the attendant e of the elevator a
reverses the tray conveyor g to send the cargo one by one to the door of the elevator cage d, and the driver k of the forklift j drives the forklift j installed on the floor to move the cargo to the elevator cage d.
Transport the cargo from the doorway to the designated location.

In addition, as another conventional example, there is an example in which a forklift l is arranged in place of the conveyor g fixed in the elevator car d in the above-mentioned conventional example, and furthermore, as shown in FIG. 8, the elevator car d There is also an attempt to install an unmanned electric trolley m equipped with a battery inside the elevator car, and to operate the electric trolley m by remote control to load cargo into the elevator cage d or unload it from the elevator cage d. .

[Problems to be solved by the invention] However, in the conventional system shown in FIGS. It still requires a lot of human power and time to determine the floor level, and unmanned electric trolleys equipped with batteries are powered by batteries, so the transport output is poor and there is space between the floor and the elevator cage. Since it is not possible to overcome the steps that occur from time to time, there are problems such as the need to provide a bridge in the elevator car for the electric trolley to run to the floor.

In view of the above-mentioned circumstances, the present invention has been developed to perform tasks such as loading cargo into the elevator cage, discharging the cargo in the elevator cage to the floor of the required floor, and moving the elevator cage to the floor to which the cargo is to be delivered. This was done with the aim of automating everything, reducing the number of workers and shortening work time.

[Means for Solving the Problems] The present invention provides an elevator car that is operated by electric power supplied and signals sent and received through the control panel of a general elevator, and an elevator car that is housed within the elevator cage when the elevator car is raised and lowered.
