Specifically, the charging device 40 includes a resistor (not shown), and when the power generation means 37 generates power due to rolling of the roller 33 even though the storage battery 39 is fully charged, the power generation means 37 generates power. Power is passed through the resistor to control consumption.

The inverter 42 is a device that converts the frequency of the electric current supplied from the storage battery 39 to the rolling means 36 and the moving means 35 under the control of the control microcomputer 41.

The movement (lateral movement) of the car 2 of the elevator 1 configured as described above along the lateral movement path C will be explained. The car 2 of this embodiment moves laterally as the lateral moving device 14 moves laterally.

As shown in FIGS. 4 and 5, the lateral movement of the car 2 in this embodiment is from one side (hoistway A side) to the other side (hoistway B side) of the elevator moving device 13 in which the cars 2 are arranged side by side. It is a movement towards. Specifically, during lateral movement, the lateral movement device 14 transitions from a state where it is coupled to the coupling portion 22 of the elevation movement device 13 on one side to a state where it is coupled to the coupling portion 22 of the elevation movement device 13 on the other side. As a result, the car 2 connected to the lateral movement device 14 moves laterally together with the lateral movement device 14. For example, as shown in FIG. 5, when the car 2 of this embodiment wants to move upward by overtaking the car 2 that is stopping or moving above, it moves laterally and ascends and descends in the adjacent hoistways A and B.

When the lateral movement device 14 moves laterally, the control microcomputer 41 controls the thrust of the movement means 35 or the rolling means 36 to accelerate the lateral movement device 14. In this embodiment, the control microcomputer 41 controls the inverter 42 to supply current of a predetermined frequency to the moving means 35, thereby accelerating the lateral moving device 14 to a predetermined speed. Further, the control microcomputer 41 controls the thrust of the moving means 35 to be cut off when the lateral moving device 14 accelerates to a predetermined speed. When the thrust of the moving means 35 is cut off, the lateral movement device 14 coasts along the lateral movement path C. Furthermore, the control microcomputer 41 can control the moving means 35 to supply a current of a predetermined frequency again when the lateral moving device 14 is coasting and decelerates to a predetermined speed or less. Note that the configuration is not limited to this, and the control microcomputer 41 can also control the lateral movement device 14 so that it can move at a substantially constant speed after the lateral movement device 14 accelerates to a predetermined speed.

Further, in this embodiment, the rolling means 36 rolls the roller 33 to assist the lateral movement of the lateral movement device 14 by the movement means 35. For example, if the car 2 has a large load and the thrust of the moving means 35 alone cannot provide sufficient acceleration, or if a problem occurs in the moving means 35, the rolling means 36 causes the rollers 33 to roll. , assists the lateral movement of the lateral movement device 14.

When the position detector 34 detects that the lateral movement device 14 has moved to a predetermined position, the control microcomputer 41 controls the lateral movement device 14 to decelerate and stop. Specifically, when decelerating the lateral movement device 14, the control microcomputer 41 controls the inverter 42 to cut off the thrust of the movement means 35 while controlling the power generation means 37 to generate electricity.

As shown in FIG. 8, the roller 33 (specifically, the rolling portion 43) is in contact with the horizontal guide rail 12, and as the horizontal movement device 14 and the car 2 move laterally, the roller 33 (specifically, the rolling portion 43) is in contact with the horizontal guide rail 12. Roll in contact with each other. Moreover, in this embodiment, the rollers 33 are provided so that both the rollers 33 provided in the upper part and the rollers 33 provided in the lower part are always in contact with the horizontal guide rail 12. That is, the roller 33 always rolls as it moves laterally.

When the power generating means 37 is generating power, rotational resistance is generated in the rolling motion of the roller 33. That is, when the power generation means 37 is generating power, a force is applied to the lateral movement device 14 to decelerate it due to rotational resistance. The control microcomputer 41 of the present embodiment controls the charging device 40 (power generation control section) so that the power generation means 37 generates power when the lateral movement device 14 decelerates, so the control microcomputer 41 controls the charging device 40 (power generation control section) so that the power generation means 37 generates power. Such rotational resistance causes the lateral movement device 14 to be braked and decelerated.

The electric power generated by the power generation means 37 is stored in the storage battery 39 and used for the operation of the car 2. Specifically, the electric power generated by the power generating means 37 is once stored in the storage battery 39 and then supplied to the moving means 35 or the rolling means 36 to operate the car 2 (specifically, for lateral movement). used. Further, the power generated by the power generation means 37 is also supplied to equipment inside the car 2 (for example, electric lights) via the storage battery 39.

According to the elevator 1 configured as described above, electric power can be generated by the rolling of the rollers 33, and the electric power obtained by the generated electricity is used to operate the car 2. Therefore, at least a part of the electric power required for the operation of the car 2 is transferred to the rollers 33. It can be supplied by power generation by the rolling of. Therefore, the power consumption related to the operation of the car 2 can be suppressed.

Furthermore, since the timing at which the rollers 33 generate electricity can be controlled by the power generation control unit (charging device 40), the generation of electricity by the rollers 33 increases the resistance to rolling of the rollers 33, which adversely affects the operation of the car 2. can be suppressed.

Furthermore, since the rollers 33 can be driven by the rolling means 36, the movement of the car 2 can be assisted by the rollers 33.

Further, the moving device 4 includes a lateral moving device 14 that moves the car 2 in the lateral direction, and the guide rail 5 has a lateral guide rail 12 that extends in the lateral direction and guides the lateral movement of the lateral moving device 14. In the power generation means 37, the roller 33 generates power by rolling when the lateral movement device 14 moves laterally. Therefore, electric power can be generated by the rolling of the rollers 33 when the car 2 moves laterally.

Further, the power generation control unit controls the power generation means 37 to generate power by rolling the rollers 33 when the car 2 needs to be braked. Therefore, the kinetic energy of the car 2 can be used to generate electricity, resulting in good energy efficiency.

Further, a section (joint section D) in which the reaction plate 24 is not arranged is formed in the lateral movement path C, and the moving means 35 is moved in the extending direction of the lateral movement device 14 by a distance greater than the distance of the section in which the reaction plate 24 is not arranged. A plurality of them are provided spaced apart. Therefore, at least one of the plurality of moving means 35 can be located in the section where the reaction plate 24 is arranged, so that the car 2 can be reliably moved laterally on the lateral movement path C.

Further, since a plurality of rollers 33 are provided spaced apart in the direction in which the lateral movement device 14 extends, the rollers 33 can contact the lateral guide rail 12 at a plurality of positions in the direction in which the lateral movement device 14 extends. Therefore, the lateral movement device 14 can lateral movement in a stable state.

Further, the power generation means 37 is configured to be able to generate power by rolling the roller 33 provided at the lower part of the lateral movement device 14. Therefore, the rollers 33 provided at the lower part due to gravity can reliably come into contact with the horizontal guide rail 12, so that electric power can be reliably generated as the car 2 moves.

Further, at least two rollers 33 are provided above and below the lateral movement device 14 and spaced apart in the extending direction of the lateral movement device 14 , and at least two rollers 33 are provided above and below the lateral movement device 14 . At least one is provided spaced apart in the stretching direction. Therefore, the lateral movement device 14 can lateral movement in a stable state.

Further, a section (seam portion D) in which the lateral guide rail 12 is not arranged is formed in the lateral movement path C, and the roller 33 is moved for a distance equal to or longer than the section in which the lateral guide rail 12 is not arranged in the extending direction of the lateral movement device 14. Since three or more are provided spaced apart from each other, it is possible to contact the lateral guide rail 12 at a plurality of positions in the extending direction of the lateral moving device 14. Therefore, the lateral movement device 14 can lateral movement in a stable state.

Although the embodiments of the present invention have been described above with reference to one example, the present invention is not limited to the embodiments described above, and various changes can be made without departing from the gist of the present invention.

For example, although a case has been described in which the mobile device 4 is driven by electric power, the configuration is not limited to this, and it may be driven by other than electric power (for example, an engine). When such a configuration is adopted, the electric power generated by the rolling of the rollers 33 can be used for equipment inside the car 2 (for example, electric lights).

Furthermore, although the case where the car 2 is generated when the car 2 moves horizontally has been described, the configuration is not limited to this, and it is also possible to generate electricity when the car 2 moves vertically, or when the car 2 is moving vertically. It is also possible to generate power both when moving horizontally and when moving laterally.

Furthermore, although the elevator 1 has been described as an example of the elevator 1 having a plurality of hoistways A and B and a lateral movement path C formed between the hoistways A and B as the movement path 3, the present invention is not limited to such a configuration. The present invention can also be applied to an elevator 1 in which one car 2 moves in one hoistway A, B.

Moreover, although the case has been described in which the electric power generated by the rolling of the rollers 33 is stored, the present invention is not limited to such a configuration, and the generated electric power can also be used for the operation of the car 2 without being stored.

Furthermore, although a case has been described in which the motor generator 38 is provided in which the rolling means 36 and the power generation means 37 are integrated, the present invention is not limited to such a configuration, and the rolling means 36 and the power generation means 37 may be configured as separate bodies. You can also do it.

Further, although the case has been described in which the motor generator 38 is an in-wheel motor configured integrally with the roller 33, the present invention is not limited to such a configuration, and the motor generator 38 and the roller 33 may be configured as separate bodies. .

Furthermore, although the case has been described in which the lateral movement device 14 moves over the entire area of the lateral movement path C mainly by the propulsive force of the movement means 35, it is not limited to such a configuration. For example, when the lateral movement path C is long in the left-right direction and the section where the reaction plate 24 is not provided is longer than the length of the lateral movement device 14, the section where the reaction plate 24 is not provided is the rolling means 36. It can also be configured to move using a propulsive force obtained by rolling the rollers 33.

In addition, although the power generation means 37 has been described for generating power by the rolling of the roller 33 provided at the lower part of the lateral movement device 14, it is not limited to such a configuration. It can also be configured to generate electricity through rolling. With such a configuration, even if the lateral movement device 14 floats upward around the car connection portion 32 due to the weight of the car 2, power generation can be ensured.

Furthermore, although a case has been described in which the power generation means 37 is controlled to generate power when the car 2 decelerates, the configuration is not limited to this, and for example, when the car 2 accelerates or when the car 2 moves at a constant speed. The moving speed (acceleration) of the car 2 can also be adjusted by generating electricity at the same time.
