[Problem that the idea aims to solve]

By the way, the baggage is transferred between the roller conveyor on the car side and the roller conveyor on the floor side. When transferring the package to another person, the level of the roller conveyor on the side receiving the package is the same as the level of the roller conveyor on the side receiving the package. It is desirable that it is slightly below the level of the roller conveyor. Therefore, in a passenger elevator, when stopping the elevator car at the destination floor, , the landing is controlled according to the level relationship described above. In addition, in elevators for people temporarily installed at construction sites, relatively long loads are Since the elevator car also has to be transported, the elevator car has a long horizontal spacing. The main basket is used.

0004 However, conventional baggage transfer using a combination of elevator and roller conveyor The device uses a landing control method that matches the elevator car floor with the floor surface of each floor. Therefore, the level of the car-side roller conveyor and the floor-side roller conveyor is at the specified level mentioned above. It is extremely difficult to control implantation to achieve a level relationship. In particular, in the case of long-span elevator cars, up to 10 There may be a difference of about 1 cm, and in such cases, the implantation control system automatically In a elevator, it is possible to control the level relationship between both roller conveyors to a predetermined level. It's almost impossible. As a result, the level of the roller conveyor on the baggage receiving side is lower than that of the roller conveyor on the baggage handing side. If the level is significantly higher than that in A, the delivery of the package by roller conveyor will be delayed. becomes impossible.

[0005] Therefore, by manually operating the control panel inside the elevator car, both rollers were controlled. The elevators are arranged so that the level relationship between the conveyors is such that it is easy to automatically transfer cargo. It is conceivable to control the landing position of the data cage, but the eye level of the operator The level relationship between both roller conveyors changes depending on the However, there was a problem in that the control was troublesome and complicated. This invention was developed in consideration of these points, and is a method for mutually receiving and receiving packages. The leveling of both the car side and floor side conveyors can be done easily and accurately. The purpose is to provide a baggage transfer device that is capable of handling cargo.

This is a protective fence that surrounds the periphery of the roller conveyor 8 on the floor side of this protective fence 15. An opening/closing gate 17 is provided on the storage side.

[0011] Next, the operation of the embodiment configured as described above will be explained. For example, on the lowest floor (basement floor) of a building, an electric forklift or the like is used to remove car 2. A place where the luggage 18 (see Figure 3) loaded on the roller conveyor 6 is transported to the destination floor. If the operator enters car 2, first open and close the opening/closing gate on the floor where the cargo was loaded. This will release the interlock of the elevator control system and allow the elevator to close. Make the control system ready for operation. In such a state, by operating the control panel 3, the elevator car 2 can be moved to the specified position. Run towards the target floor.

0012 When car 2 approaches the destination floor, a well-known landing device operates to slow down car 2. while automatically stopping at the destination floor. At this time, the upper and lower level detectors 11 and 12 are connected to the roller controllers on the target floor. By detecting the presence or absence of reflected light reflected by the reflector 10 of the bear 8, it is possible to determine the location of the target floor. Detects the relative level between the roller conveyor 8 and the car side roller conveyor 6, and sends the detection signal. The signal is output to the level determination circuit 13. In the level determination circuit 13, the car side roller conveyor is determined based on the input detection signal. The level of A6 is slightly above (or below) the level of roller conveyor 8 on the destination floor side. By determining whether or not the level is present and outputting the determination result to the level display 14 , by turning on or off the lamps 14a and 14b to connect the roller conveyors 6 and 8. Displays whether the level relationship is in a predetermined state.

[0013] Here, the level detector 1 when the car 2 is stopped by the well-known automatic landing control. Assuming that the positional relationship between 1 and 12 and the reflecting plate 10 is as shown in FIG. 5(a), The lamp 14a of the level indicator 14 is on, and the lamp 14b is off. Therefore, the operator can check the status of the lamp on the level indicator 14. The level of the roller conveyor 6 on your side is lower than the level of the roller conveyor 8 on the destination floor. By operating the control panel 3 again, the elevator is started and the car is turned off. 2 slightly upward (or downward) at low speed. As a result, the irradiated light from the level detectors 11 and 12 is shown in FIG. 5(b). When the positional relationship is such that both of them are irradiated and reflected by the reflector plate 10, the level display The lamps 14a and 14b of the container 14 are both lit, and the roller conveyor 6 on the car side is the target. This indicates that the roller conveyor 8 on the floor side has reached a suitable level for receiving and receiving parcels. Inform.

[0014] When the operator recognizes this condition, he stops elevator car 2 and removes the cargo. Shift to delivery operation. When transferring the cargo 18 in the basket 2 onto the floor-side roller conveyor 8 of the destination floor, First, the operator in car 2 opens the opening/closing gate 17 of the destination floor, and the car side roller control Connect one end of the power supply cable 9 extending from the conveyor 6 to the floor-side roller conveyor 8.
