The hoisting machine 5 and the control device 6 may be provided in the hoistway 3 . The hoisting machine 5 may be provided at the top of the hoistway 3 or may be provided in the pit of the hoistway 3 .

FIG. 1 shows a state in which a car 1 is stopped at a landing 7 formed in a building A. As shown in FIG. FIG. 2 is a diagram showing an example of the car 1 stopped at the landing 7 viewed from the landing 7. As shown in FIG. FIG. 2 shows the door of the landing 7 and the door of the car 1 open.

A car room 8 is formed in the car 1 . The car room 8 is a space for a user to ride. The car 1 also includes a charging device 9 . A charging device 9 is a device for charging the battery 10 . 1 and 2 show an example in which the charging device 9 is provided on the back wall of the car room 8. FIG. FIG. 2 also shows an example in which the charging device 9 can charge a plurality of batteries 10 simultaneously.

The battery 10 is detachable with respect to the charging device 9 . A user can attach the battery 10 to the charging device 9 in the cab 8 . In the example shown in FIG. 2, three batteries 10 are attached to the charging device 9 . In the example shown in FIG. 2, it is possible to attach another battery 10 to the charging device 9 .

A user can remove the battery 10 from the charging device 9 in the car 8 . The user can carry the battery 10 removed from the charging device 9 , ie, the battery 10 charged by the charging device 9 , out of the car 1 . The battery 10 is portable, and has a size and weight that allow the user to carry it through the doorway of the car 1 .

FIG. 3 is a diagram for explaining the functions of the elevator device. As shown in FIG. 3, power for the control device 6 is basically supplied from a commercial power supply 11. As shown in FIG. The control device 6 includes an operation control section 21 , a charging/discharging control section 22 and an interruption detection section 23 . Operation control part 21 controls automatic operation. Automatic operation is operation for sequentially responding to registered calls by car 1 . The calls include hall calls and car calls.

Automatic operation includes power running operation and regenerative operation. The power running operation is an operation when the torque output direction of the hoisting machine 5 and the direction in which the sheave of the hoisting machine 5 rotates are the same. The weight of the counterweight 2 is set in advance so as to match the weight of the car 1 when a load of 45 to 50% of the rated load is acting on the car 1, for example. That is, when there are no users in car 1, car 1 is lighter than counterweight 2. In this case, the operation for lowering the car 1 when there is no user in the car 1 is the power running operation.

On the other hand, regenerative operation is an operation when the torque output direction of the hoisting machine 5 and the direction in which the sheave of the hoisting machine 5 rotates are different. For example, the operation to raise the car 1 when there is no user in the car 1 is the regenerative operation. In regenerative operation, the hoist 5 functions as a generator. In the example shown in the present embodiment, if the battery 10 is attached to the charging device 9 , the battery 10 is charged with the electric power generated in the regenerative operation, that is, the electric power regenerated by the hoisting machine 5 . A function of charging the battery 10 is implemented by the charge/discharge control unit 22 .

The cutoff detection unit 23 detects that the power from the commercial power supply 11 has been cut off. For example, when a power outage occurs in building A or in an area including building A, cutoff detection unit 23 detects that power from commercial power source 11 has been cut off. A cable 14 is connected between the car 1 and the controller 6 . When the interruption detection unit 23 detects that the power from the commercial power source 11 is interrupted, the charge/discharge control unit 22 supplies power from the battery 10 attached to the charging device 9 to the devices necessary for operation. supply. The equipment includes a hoist 5 and a control device 6 . The battery 10 functions as an emergency power supply during a power outage in the elevator system.

Moreover, as described above, the battery 10 is detachable from the charging device 9 , and the user can carry the battery 10 removed from the charging device 9 out of the car 1 . Therefore, in the example shown in this embodiment, the user can use the battery 10 for specific equipment other than the elevator system.

For example, a battery case 12 is arranged outside the car 1 . The battery case 12 is preferably provided at a location not associated with the elevator system. The battery 10 is attachable to and detachable from the battery case 12 . When the battery 10 is attached to the battery case 12, power is supplied from the battery 10 to a specific device. In the following, the device will also be referred to as an external device.

As an example, the external device is an electric bicycle. The user removes the battery 10 from the charging device 9 in the car room 8 when going out on the electric bicycle. The user gets off the car 1 while holding the battery 10 removed from the charging device 9, and attaches the battery 10 to the battery case 12 provided on the electric bicycle. As a result, the electric power from the battery 10 can assist the rotation of the pedals of the electric bicycle.

Also, when the user returns to the building A on the electric bicycle, the user removes the battery 10 from the battery case 12 of the electric bicycle. Then, the user gets on the car 1 with the battery 10 removed from the electric bicycle. When the user gets on the car 1, the user attaches the battery 10 to the charging device 9 in the car room 8. - 特許庁The user gets off the car 1 with the battery 10 attached to the charging device 9. - 特許庁The user can remove the battery 10 from the charging device 9 again when using the electric bicycle next time.

As another example, the external device may be a shared facility installed in building A. Common facilities are facilities that are shared by people who use building A. Shared facilities include water pumps, entrance hall lamps, and emergency staircase lamps. The battery case 12 is provided in the building A when power from the battery 10 is supplied to shared facilities.

In the example shown in this embodiment, the battery 10 can be charged by the charging device 9 and the user can use the battery 10 outside the car 1 as well.

In addition, when the building A is an apartment, the elevator system is often used by a small number of people. For example, if only one person is in car 1, car 1 will be lighter than counterweight 2. That is, such an elevator apparatus is often operated in a state where the car 1 is lighter than the counterweight 2 . The charging device 9 may be used to increase the weight of the car 1 side in such an elevator device. In an elevator device installed in an apartment building or the like, energy efficiency can be improved by using the charging device 9 as a virtual weight on the car 1 side.

The program is stored in memory 32 . The control device 6 implements the functions of the respective units indicated by reference numerals 21 to 23 by causing the processor 31 to execute programs stored in the memory 32 . A semiconductor memory or the like can be used as the memory 32 .

FIG. 5 is a diagram showing another example of hardware resources of the control device 6. As shown in FIG. In the example shown in FIG. 5, controller 6 comprises processing circuitry 30 including processor 31 , memory 32 and dedicated hardware 33 .
