Description

The present invention relates to an elevator in which a car traverses on a traverse track.

The inventors of the present application have proposed that a car and a lift drive device for raising and lowering a car are separated and coupled, and that the lift drive device is located in an adjacent hoistway through a horizontal track provided on the lift drive device. We have proposed an elevator that can shift cars (Patent Document 1).

JP 2016-121021 A

In such an elevator in which the car laterally moves on the lateral track, when the lateral movement of the car is performed by a linear motor, the magnetic circuit is divided due to the gap between the parallel lifting and lowering drive devices, and the propulsive force decreases. However, the car may not be able to move sideways smoothly.

In an elevator in which a car laterally moves on a horizontal track, the present invention relates to an elevator between laterally parallel elevator driving devices, or between both laterally parallel elevator driving devices and lateral moving units. Another object of the present invention is to provide an elevator in which a car can smoothly laterally move between two laterally moving parts arranged in parallel in the lateral direction.

The elevator of the present invention is
In an elevator in which a car and a lifting drive device for raising and lowering the car are separated and connected,
Two or more sets of the elevator car and the lift drive device are arranged side by side in the horizontal direction, or one or more lateral movers can arrange the elevator car moved from the lift drive device. are arranged so as to be able to be paralleled in the lateral direction with respect to the lifting drive device,
The lifting drive device or the lateral movement unit includes a lateral track extending in a lateral direction,
By moving in the lateral direction along the lateral track, the car moves laterally from the lateral track of the elevating drive device to the lateral direction of the other elevating drive device or the lateral movement section positioned laterally in parallel. can shift to a track, or can shift between the lateral tracks of the two side-by-side lateral moving units;
A linear motor that generates a driving force for the lateral movement is formed over the elevator car and the lifting drive device or over the elevator car and the lateral movement unit,
The car is provided with a plurality of laterally spaced propulsion force output means,
each of the plurality of propulsion force output means is configured to generate a propulsion force for the lateral movement of the car by itself or in combination with other configurations;
The plurality of propulsive force output means are defined as a boundary between the two elevator driving devices when the two elevator driving devices are horizontally arranged side by side, or when the elevator driving device and the lateral movement unit are horizontally parallel to each other. With reference to the boundary between the two laterally moving units in the case where the
In a state in which none of the plurality of propulsive force output means exceed the boundary, the driving force of the propulsive force output means that is the most forward in the lateral movement direction of the car is the driving force of the other propulsive force output means. driven to be smaller than the driving force,
When a part of the plurality of propulsive force output means exceeds the boundary, the driving force of the propulsive force output means forward of the boundary is greater than the driving force of the propulsive force output means rearward of the boundary. It is configured to be driven such that

According to this configuration, when all of the plurality of propulsive force output means have not crossed the boundary, the propulsive force output means that crosses the boundary first is driven with a smaller driving force than the other propulsive force output means. do. On the other hand, in a state where some of the plurality of propulsive force output means have crossed the boundary, the forward propulsive force output means that has already crossed the boundary is the rear propulsive force that has not yet crossed the boundary. Since the driving force is greater than that of the output means, the propulsive force output means for crossing the boundary crosses the boundary with a smaller propulsive force than the other propulsive force output means. Therefore, it is possible to reduce the influence of the decrease in propulsive force when crossing the boundary. For this reason, in the linear motor, the problem that the magnetic circuit is divided by the gap at the boundary and the car cannot move laterally smoothly is unlikely to occur. The car can be smoothly laterally moved between the two laterally moving parts when they are laterally parallel to each other, or between both laterally moving parts when two laterally moving parts are laterally parallel to each other.

Also, in the elevator,
The plurality of propulsive force output means,
When all of the plurality of propulsive force output means do not cross the boundary, the propulsive force output means that is the most forward in the lateral movement direction of the car is stopped,
In a state where some of the plurality of propulsive force output means have crossed the boundary, the propulsive force output means forward of the boundary are driven, and the propulsive force output means rearward of the boundary are stopped. may have been

According to such a configuration, since the control of the propulsion force output means when passing through the boundary is ON/OFF control, the control can be easily performed.

Also, in the elevator,
The linear motor has a primary side structure provided in the car and a secondary side structure provided in the lifting drive device or the lateral movement unit,
A part of the linear motor may also serve as the propulsion force output means, and may be a plurality of the primary sides arranged in the car at intervals in the lateral direction.

According to such a configuration, it is possible to realize a configuration in which the car can be smoothly laterally moved by the linear motor.

Also, in the elevator,
The propulsive force output means is provided separately from the linear motor, is arranged laterally apart from the rotary drive source in the car, and is rotated by the drive force transmitted from the rotary drive source. and a plurality of drive wheels for producing said thrust for said lateral movement.

According to such a configuration, the propulsive force output means provided separately from the linear motor can assist the reduction in the propulsive force of the linear motor when the boundary is passed.

In addition, the elevator
You may provide the in-wheel motor by which the said rotational drive source and the said driving wheel were made integral.

According to such a configuration, it is possible to simplify the configuration of the elevator in which the car can laterally move between the parallel up-and-down driving devices.

As described above, according to the present invention, in an elevator in which a car laterally moves on a horizontal track, it is possible to provide an elevator in which the car can smoothly laterally move between the parallel elevator drive devices.

A first embodiment, which is one embodiment of the present invention, will be described below with reference to FIGS. 1 to 10. FIG. The elevator 1 is an elevator (elevating separation type elevator) in which a car 3 and an elevating drive device 4 for elevating the car 3 are separated and connected. In this elevator 1, the car 3 itself does not have a lifting function.

As shown in FIG. 5, the elevator 1 comprises a plurality of hoistways 2 extending vertically over a plurality of floors in the building, a car 3 freely moving on the hoistway 2, and the hoistway 2. and a lifting drive device 4 that moves vertically. Further, the car 3 can move up and down in the hoistway 2 and stop at the landing 5 provided on each floor of the building.

Further, in the elevator 1, two or more sets of the car 3 and the lifting drive device 4 are arranged side by side in the horizontal direction. In the configuration shown in FIG. 5, two sets of the car 3 and the lifting drive device 4 are arranged side by side in the horizontal direction.

In this elevator 1, two hoistways 2 are provided in parallel on the right and left sides of the drawing, and extend vertically for five floors. Furthermore, the parallel hoistways 2A and 2B are in communication with each other so that the car 3 can move laterally (an arrow indicates the third floor portion). A gate that can be opened and closed is provided in these communicating portions, and the movement of the car 3 can be restricted by closing the gate. Although only one place is marked with a reference numeral, all of the ten boxes shown in FIG.

The physical configuration of the elevator 1 is in common with the configuration described in Patent Literature 1, which was previously filed by the inventor of the present application. This physical configuration is described below. FIG. 1 shows a state in which the elevator car 3 is connected to the lift drive device 4 . As shown in FIG. 2, the lifting drive device 4 is arranged along a guide rail 21 provided inside the hoistway 2A and is configured to be liftable by a suspension rope 22. As shown in FIG. Here, in the conventional traction elevator, the car itself connected to the suspension rope is raised and lowered. On the other hand, the conventional car portion is replaced with a lift drive device 4, and the lift drive device 4 is configured to have a horizontal track 41 extending in the horizontal direction (horizontal direction in the drawing). Therefore, as shown in FIG. 4, the car 3 moves laterally along the horizontal track 41A of the lifting drive device 4A on the right side of the drawing, thereby moving the other lifting drive device located on the left side of the drawing side by side in the horizontal direction. It is possible to shift to the lateral track 41B of the device 4B.

The lift drive device 4 does not prevent the car 3 of another elevator or the lift drive device 4 from passing vertically through an empty space without the car 3 in the separated state where the car 3 is not connected. is configured as That is, in one hoistway 2A, 2B, the movement locus of one elevation driving device 4 and the movement locus of another elevation driving device 4 are configured so as not to overlap. With such a configuration, the cars 3 that move vertically and horizontally can intersect, and a layout of structures such as buildings that is advantageous in terms of space saving can be achieved. Although the configuration of the present embodiment is a traction type, other driving methods can also be used.

FIG. 3 shows the car 3 of this embodiment from the front side. The car 3 protrudes laterally from a car main body 31 on which a user boards, and on the rear surface of the car main body 31, and travels along a horizontal track 41 of the elevation drive device 4. A portion 32 is provided. In addition, the track running portion 32 may be provided on the side surface of the car body 31, and the present invention is such that the track running portion 32 provided on the side surface of the car body 31 crosses the later-described boundary B in the front-rear direction. Configuration is also applicable.

The car main body 31 is provided with a car door 30 for communicating inside and outside by opening and closing. The car door 30 of the present embodiment is a double door in which a pair (two) of opening and closing units (one door or a unit composed of a plurality of doors that move in the same direction when opening and closing) are provided symmetrically. It is In addition, the hall door is also made into the same form. In this embodiment, since the car 3 moves vertically and horizontally over the hoistways 2A and 2B, the outside of the car main body 31 is provided to absorb the shock in case another car 3 collides with it. It is also possible to provide a damping device located at . This shock absorber can be directly fixed to the car body 31, or it is movably provided in the lifting drive device 4 and positioned so as to surround the car body 31 (fixed directly to the car body 31). not).

FIG. 4 shows a state in which the car 3 is moving along the horizontal tracks 41A and 41B between the two elevator drive devices 4A and 4B arranged in the horizontal direction. A linear motor 6 that generates a driving force for lateral movement is formed across the car 3 and the lift drive device 4 (in this embodiment, across the track running section 32 and the horizontal track 41). Due to the formation of the linear motor 6, the car 3 and the lift drive device 4 (in this embodiment, the track running section 32 and the horizontal track 41) move laterally relative to each other. As a result, the car 3 laterally moves from the lift drive device 4A, passes through the boundary B, and moves to the lift drive device 4B.

The track running part 32 has a first running part 321 located on the near side in the depth direction of the car 3, and a first running part 321 provided on the far side of the first running part 321 and having a larger dimension in the vertical direction than the first running part 321. and a second running portion 322 . Further, as shown in FIG. 6, the horizontal track 41 includes a first track portion 411 located on the front side of the car 3 in the depth direction, and a first track portion 411 provided on the back side of the first track portion 411. and a second track portion 412 having a larger dimension in the vertical direction than 411 .

Power supply to the linear motor 6 (primary side structure 61 described later) may be performed from a power supply device provided on either the car 3 or the lift drive device 4 side. is supplied from a power supply device 33 provided in the car 3, as shown in FIG. Further, power supply to the linear motor 6 may be performed from an external power source provided other than the car 3 and the lift drive device 4 .

In the following description, it is assumed that the car 3 laterally moves leftward from the lift drive device 4A, passes through the boundary B, and moves to the lift drive device 4B. As shown in FIG. 7, the car 3 (in this embodiment, the track running section 32) is provided with a plurality of propulsion force output means 34 spaced apart in the lateral direction. Each of the plurality of propulsive force output means 34 is configured to generate a propulsive force for lateral movement of the car 3 in combination with another configuration (specifically, a reaction plate 43 to be described later). In addition, the plurality of propulsion force output means 34 are arranged with reference to the boundary B between the two elevation drive devices 4A and 4B when the two elevation drive devices 4A and 4B are arranged side by side in the horizontal direction. In the state where none of 34A and 34B crosses the boundary B, the forwardmost propulsive force output means 34B (the propulsive force output means 34B located on the left side in FIG. 7) in the lateral movement direction of the car 3 is driven. It is configured such that the drive force is smaller than the driving force of the other propulsive force output means 34A (the propulsive force output means 34A located on the right side in FIG. 7). That is, in this state, the other propulsive force output means 34A is driven to push out the forwardmost propulsive force output means 34B in the lateral movement direction.

Further, when a part of the plurality of propulsive force output means 34A and 34B (specifically, the propulsive force output means 34B) exceeds the boundary B, the propulsive force output means 34B ahead of the boundary B ( The driving force of the propulsive force output means 34B located on the left side is driven to be greater than the driving force of the propulsive force output means 34A located behind the boundary B (the propulsive force output means 34A located on the right side in FIG. 7). is configured as follows. That is, in this state, the forwardmost propulsive force output means 34B is driven to pull the other propulsive force output means 34A in the lateral movement direction.

In this elevator 1, when all of the plurality of propulsive force output means 34A and 34B have not crossed the boundary B, the propulsive force output means 34B that crosses the boundary B earlier than the other propulsive force output means 34A. Drive with a small driving force. On the other hand, when some of the plurality of propulsive force output means 34A and 34B have crossed the boundary B, the forward propulsive force output means 34B, which has already crossed the boundary B, has not crossed the boundary B yet. In order to drive with a larger driving force than the rear propulsive force output means 34A in the state, the propulsive force output means 34A crossing the boundary B is driven with a smaller propulsive force than the other propulsive force output means 34B. exceed B. Therefore, it is possible to reduce the influence of the drop in propulsive force when crossing the boundary B. Therefore, the problem that the car 3 cannot move smoothly laterally due to the magnetic circuit being cut off by the gap at the boundary B in the linear motor 6 is unlikely to occur. can move sideways smoothly.

In this embodiment, the plurality of propulsive force output means 34A, 34B are arranged in the forwardmost direction in the lateral movement direction of the car 3 when all of the plurality of propulsive force output means 34A, 34B do not cross the boundary B. In a state where a certain propulsive force output means 34B is stopped and a part of the plurality of propulsive force output means 34A and 34B (specifically, propulsive force output means 34B) exceeds the boundary B, forward propulsion beyond the boundary B The force output means 34B is driven, and the propulsion force output means 34A behind the boundary B is stopped. In this configuration, the control of the propulsive force output means 34A and 34B when passing through the boundary B is on/off control (drive or stop control), so control can be easily performed.

In addition, in the linear motor 6 of the present embodiment, the primary side structure 61 is provided in the car 3, and the secondary side structure 62 is provided in the lift drive device 4 (see also FIG. 6). A part of the linear motor 6 (specifically, the primary side structure 61) also serves as the propulsive force output means 34 (see FIG. 7). Specifically, a plurality of primary side structures 61 arranged laterally apart in the car 3 of the linear motor 6 also serve as the propulsive force output means 34 . That is, the propulsive force output means 34 is configured to generate a propulsive force for lateral movement of the car 3 in combination with the configuration 62 on the secondary side. In this configuration, the linear motor 6 can realize a configuration in which the car 3 can be smoothly laterally moved. In this embodiment, the linear motor 6 is an induction linear motor, but may be a synchronous linear motor.

The primary side arrangement 61 is, for example, an armature containing coils. In this linear motor 6, the primary side structure 61 is divided into a front primary side structure 61B and a rear primary side structure 61A in the direction of progress of lateral movement. After the car 3 crosses the boundary B, the current in the configuration 61B on the primary side ahead in the direction of travel is turned off, the current in the configuration 61A on the rear primary side is turned on, and after the car 3 crosses the boundary B, the configuration 61B on the front primary side is turned on and the current in the rear primary configuration 61A is turned off.

In this embodiment, the elevator car 3 laterally moves from the elevator drive device 4A, passes through the boundary B, and moves to the elevator drive device 4B. Detects position relative to

In this car 3, the propulsive force output means 34 (primary side structure 61), the control microcomputer 35, the position detection section 36, the driver 37, and the guide rollers 38 are arranged in the track running section 32. At least one of the members other than the guide rollers 38 may be arranged in a configuration other than the track running section 32 (for example, the car main body 31).

The control microcomputer 35 controls lateral movement of the car 3 (see FIG. 8). Further, the control microcomputer 35 can grasp whether or not the lateral movement of the car 3 is at the target position (the position overlapping the lift drive device 4A or the lift drive device 4B). Furthermore, the control microcomputer 35 is connected to the position detector 36 and the driver 37 .

In this embodiment, the control microcomputer 35 determines whether or not the car 3 is at the target position based on the detection result of the position detection unit 36, the moving direction of the car 3, and the propulsive force output means 34A and 34B. 41 and whether or not the rear propulsive force output means 34A has crossed the boundary B. Further, the control microcomputer 35 controls the lateral movement of the car 3 by outputting a signal indicating whether to drive or stop the propulsive force output means 34 to the driver 37 .

The position detection unit 36 is a sensor that detects the relative position of the car 3 with respect to the elevator drive devices 4A and 4B (specifically, a linear scale 44 described later). Furthermore, the position detector 36 is connected to the control microcomputer 35 . In this embodiment, the position detection unit 36 is arranged at a position facing the linear scale 44 (specifically, a position facing the linear scale 44 from the front side). Also, two position detection units 36 are provided, and for example, one each is arranged at both ends in the lateral direction of the surface of the track running unit 32 facing the linear scale 44 . The position detector 36 may be a limit switch that detects whether or not the propulsive force output means 34 has crossed the boundary B.

The driver 37 is connected to the propulsive force output means 34 and the power supply device 33 . Further, the driver 37 switches between driving and stopping the propulsive force output means 34 (on/off of the current of the primary side configuration 61). In this embodiment, one driver 37 switches currents of a plurality of (for example, two) propulsive force output means 34 . Specifically, this driver 37 is a multi-axis driver. In addition, the car 3 may be provided with a plurality of drivers 37 provided for one propulsive force output means 34 .

The guide rollers 38 are non-powered rollers that support the horizontal track 41 (lifting drive device 4) of the car 3 (see FIG. 7). Further, the guide roller 38 is provided to keep the distance between the primary side structure 61 and the secondary side structure 62 of the linear motor 6 constant. A part of the guide roller 38 is exposed from the track running portion 32 (specifically, the second running portion 322) and comes into contact with the horizontal track 41 (specifically, the second track portion 412) of the lifting drive device 4. (see also Figure 2).

In this car 3, a plurality of guide rollers 38 (for example, three or more, three in this embodiment) are provided in order to run smoothly on the horizontal track 41 without rattling (see FIG. 7). ). Specifically, the guide rollers 38 are arranged with a gap in the lateral direction, and one propulsive force output means 34 (primary side structure 61) is arranged between a pair of adjacent guide rollers 38 . That is, the guide rollers 38 include a first guide roller 381 arranged behind the rear propulsive force output means 34A, a second guide roller 382 arranged in front of the forward propulsive force output means 34B, and a propulsion and a third guide roller 383 arranged between the force output means 34A, 34B.

In this embodiment, a part of the plurality of guide rollers 38 (specifically, the first guide roller 381 and the second guide roller 382) protrudes downward from the track running portion 32 and is exposed, above the lateral track 41 (specifically, the upward facing surface of the second track portion 412) (see also FIG. 2). Furthermore, the rest of the plurality of guide rollers 38 (specifically, the third guide roller 383) protrudes upward from the track running portion 32 and is exposed, and the surface facing downward of the horizontal track 41 (specifically, the downward facing surface of the second raceway portion 412).

The elevator drive device 4 includes a drive device main body 42 to which the car 3 is coupled and to which the transverse track 41 is provided, and a secondary side structure 62 and a linear scale 44 of the linear motor 6 provided in the drive device main body 42. (See Figure 6).

The lateral track 41 extends laterally in a groove-like shape on the front vertical surface of the driving device main body 42 . Note that the lateral track 41 may be provided on the top surface of the drive device main body 42 or may be provided on the bottom surface of the drive device main body 42 depending on the support form of the car 3 .

The secondary configuration 62 extends laterally. Also, the secondary side arrangement 62 is arranged in a transverse track of the drive body 42 . The secondary configuration 62 includes, for example, magnetic material. Specifically, the secondary side arrangement 62 is the reaction plate 43 . The reaction plate 43 has, for example, a two-layer structure, and specifically, covers a body layer 430 made of a ferromagnetic material such as iron and the body layer 430 (for example, the front surface of the body layer 430). and a covering layer 431 made of a good conductor such as aluminum.

A linear scale 44, which is part of the linear encoder 7, extends laterally. Also, the linear scale 44 is arranged on the lateral track 41 of the driving device main body 42 . Note that the linear scale 44 may be arranged at another location on the drive device main body 42 instead of the horizontal track 41 .

Furthermore, in the elevator 1 of the present embodiment, the track running portion 32 of the car 3 is surrounded by the driving device main body 42 at the position of the horizontal track 41, so that the car 3 is coupled to the lifting drive device 4 (Fig. 4). The car 3 may be coupled to the lift drive device 4 by sandwiching the drive device main body 42 between the track running section 32 (inverted relationship with respect to FIG. 4).

Specific processing for lateral movement of the car 3 in the elevator 1 will be described with reference to the flow charts of FIGS. 9 and 10. FIG.

First, a series of processes when the car 3 moves laterally from the lift drive device 4A positioned on the right side, crosses the boundary B, and reaches the lift drive device 4B positioned on the left side will be described. As shown in FIG. 9, from the state in which the propulsive force output means 34A and 34B are both driven (step S1), it is determined whether or not the car 3 is at the target position (step S2). At this time, the control microcomputer 35 of the car 3 outputs a signal to the driver 37 to drive the driving force output means 34A and 34B together. position at the center of the front side with respect to the device 4B).

When it is determined that the car 3 is not at the target position (No in step S2), it is determined whether the traveling direction of the car 3 is leftward (step S3). At this time, the control microcomputer 35 determines whether or not the traveling direction is the left direction based on the detection result of the position detection section 36 .

When the traveling direction of the car 3 is the left direction (Yes in step S3), the rear propulsive force output means 34A is driven in the lateral movement direction, and the forward propulsive force output means 34B is stopped (step S4). , and the propulsive force output means 34A and 34B are on the same horizontal track 41 (step S5). At this time, the control microcomputer 35 determines whether or not the propulsive force output means 34A and 34B are on the same horizontal track 41 based on the detection result of the position detection section 36 .

When it is determined that the propulsive force output means 34A and 34B are not on the same lateral track 41 (No in step S5), it is determined whether or not the forward propulsive force output means 34B in the lateral movement direction has crossed the boundary B. (step S6). At this time, the control microcomputer 35 determines whether or not the forward propulsive force output means 34B has crossed the boundary B based on the detection result of the position detection section 36. FIG.

When it is determined that the forward propulsive force output means 34B has not crossed the boundary B (No in step S6), the forward propulsive force output means 34B is stopped, and while the rear propulsive force output means 34A is driven, the step It returns to judgment whether the car 3 is in the target position of S2. Specifically, the control microcomputer 35 continues to output a signal to the driver 37 to stop the front propulsive force output means 34B and drive the rear propulsive force output means 34A.

When it is determined that the front propulsive force output means 34B has crossed the boundary B (Yes in step S6), the front propulsive force output means 34B is driven and the rear propulsive force output means 34A is stopped (step S7). , the process returns to step S2 to determine whether or not the car 3 is at the target position. Specifically, in step S7, the control microcomputer 35 outputs a signal to the driver 37 to drive the front propulsive force output means 34B and stop the rear propulsive force output means 34A.

When it is determined that the propulsive force output means 34A and 34B are on the same horizontal track 41 (Yes in step S5), the forward propulsive force output means 34B is stopped and the rearward propulsive force output means 34A is driven. Then, the process returns to step S2 to determine whether or not the car 3 is at the target position. Specifically, the control microcomputer 35 continues to output a signal to the driver 37 to stop the front propulsive force output means 34B and drive the rear propulsive force output means 34A.

When it is determined that the car 3 is at the target position (Yes in step S2), the front propulsion force output means 34B and the rear propulsion force output means 34A are stopped (step S8), and the process ends. Specifically, in step S8, the control microcomputer 35 outputs a signal to the driver 37 to stop the front propulsive force output means 34B and the rear propulsive force output means 34A.

When the traveling direction of the car 3 is the right direction, the same processing as the series of processing described above is performed. Specifically, a series of processes when the car 3 moves laterally from the elevator driving device 4B located on the left side, crosses the boundary B, and reaches the elevator driving device 4A located on the right side will be described. From the state in which the propulsive force output means 34A and 34B are both driven (step S1), it is determined whether or not the car 3 is at the target position (step S2). At this time, the control microcomputer 35 of the car 3 determines whether or not the car 3 is at the target position (the central position on the front side of the car 3) based on the detection result of the position detector 36.

When it is determined that the car 3 is not at the target position (No in step S2), it is determined whether the traveling direction of the car 3 is leftward (step S3). At this time, the control microcomputer 35 outputs a signal to the driver 37 to drive the propulsive force output means 34A and 34B together, and determines whether or not the traveling direction is to the left based on the detection result of the position detection section 36. do.

When the traveling direction of the car 3 is the right direction (No in step S3), as shown in FIG. 10, the rear propulsive force output means 34B is driven in the lateral movement direction, and the forward propulsive force output means 34A is driven. is stopped (step S9), and it is determined whether or not the propulsive force output means 34A and 34B are on the same lateral track 41 (step S10). At this time, the control microcomputer 35 determines whether or not the propulsive force output means 34A and 34B are on the same horizontal track 41 based on the detection result of the position detection section 36 .

When it is determined that the propulsive force output means 34A and 34B are not on the same lateral track 41 (No in step S10), it is determined whether or not the forward propulsive force output means 34A in the lateral movement direction has crossed the boundary B. (step S11). At this time, the control microcomputer 35 determines whether or not the forward propulsive force output means 34A has crossed the boundary B based on the detection result of the position detection section 36. FIG.

When it is determined that the forward propulsive force output means 34A has not crossed the boundary B (No in step S11), the forward propulsive force output means 34A is stopped, and while the rear propulsive force output means 34B is driven, the step It returns to judgment whether the car 3 is in the target position of S1. Specifically, the control microcomputer 35 continues to output a signal to the driver 37 to stop the front propulsive force output means 34A and drive the rear propulsive force output means 34B.

When it is determined that the front propulsive force output means 34A has crossed the boundary B (Yes in step S11), the front propulsive force output means 34A is driven and the rear propulsive force output means 34B is stopped (step S12). , the process returns to step S2 to determine whether or not the car 3 is at the target position. Specifically, in step S12, the control microcomputer 35 outputs a signal to the driver 37 to drive the front propulsion force output means 34A and stop the rear propulsion force output means 34B.

When it is determined that the propulsive force output means 34A and 34B are on the same horizontal track 41 (Yes in step S10), the forward propulsive force output means 34A is stopped and the rear propulsive force output means 34B is driven. Then, the process returns to step S2 to determine whether or not the car 3 is at the target position. Specifically, the control microcomputer 35 continues to output a signal to the driver 37 to stop the front propulsive force output means 34A and drive the rear propulsive force output means 34B.

When it is determined that the car 3 is at the target position (Yes in step S2), the front propulsion force output means 34A and the rear propulsion force output means 34B are stopped (step S8), and the process ends. Specifically, in step S8, the control microcomputer 35 outputs a signal to the driver 37 to stop the front propulsive force output means 34A and the rear propulsive force output means 34B.

Next, regarding the second embodiment, mainly the differences from the first embodiment will be described. This configuration is useful when some of the horizontal tracks 41 provided in the plurality of elevation driving devices 4 are not provided with the reaction plate 43 . For example, as shown in FIG. 11, each of the plurality of propulsive force output means 34C and 34D may be configured to generate propulsive force for lateral movement of the car 3 by itself. In this case, the propulsive force output means 34C and 34D are provided separately from the linear motor 6. FIG.

The propulsive force output means 34C and 34D have a structure in which the track running section 32 or the horizontal track 41 (the track running section 32 in this embodiment) includes a rotary motor and a rotating body such as a wheel driven by the motor. The track running portion 32 and the horizontal track 41 are horizontally moved relative to each other. Specifically, the propulsive force output means 34C and 34D are arranged laterally apart from the rotary drive source (for example, rotary motor) in the car 3, and are rotated by the driving force transmitted from the rotary drive source. It consists of a plurality of drive wheels that provide the thrust for lateral movement. In this configuration, the propulsive force output means 34 provided separately from the linear motor 6 can assist the reduction in the propulsive force of the linear motor 6 when passing through the boundary, so that smooth lateral movement can be achieved. can. In addition, it is preferable that the driving force of the driving force output means 34C and 34D is larger than the driving force of the linear motor 6 in order to assist the reduction of the driving force.

In this embodiment, the propulsive force output means 34C and 34D each include a rotary drive source and drive wheels. Specifically, each of the propulsive force output means 34C and 34D is an in-wheel motor in which the rotary drive source and the drive wheels are integrated. This simplifies the structure of the elevator 1 in which the car 3 can be laterally moved between the elevator drive devices 4 arranged in parallel.

Furthermore, for example, when the car 3 laterally moves to the left, the propulsive force output means 34 of the present embodiment is set to The driving force of the propulsive force output means 34D, which is the most forward in the lateral movement direction, is driven so as to be smaller than the driving force of the other propulsive force output means 34A, 34B, 34C. Specifically, when none of the plurality of propulsive force output means 34 has crossed the boundary B, the forwardmost propulsive force output means 34D in the lateral movement direction of the car 3 is stopped.

Further, in a state where some of the plurality of propulsive force output means 34 (for example, propulsive force output means 34B, 34D) have crossed the boundary B, the propulsive force in front of the boundary B in the lateral movement direction of the car 3 The driving force of the output means 34B, 34D is configured to be greater than the driving force of the propulsive force output means 34A, 34C behind the boundary B. Specifically, when some of the plurality of propulsive force output means 34 (for example, propulsive force output means 34B and 34D) have crossed the boundary B, the propulsive force output means 34B and 34D ahead of the boundary B are driven. , the propulsive force output means 34A, 34C behind the boundary B are stopped.

In addition, the drive wheels of the propulsive force output means 34C behind the boundary B may be driven without being stopped. That is, the driving force of the propulsive force output means 34B in front of the boundary B is driven to be greater than the driving force of the propulsive force output means 34A behind the boundary B, and the propulsive force output means 34C behind the boundary B is driven forward. may be driven with the same driving force as the driving force output means 34D.

Also, the propulsion force output means 34C and 34D may not include a rotational drive source. In this case, the propulsion force output means 34C and 34D are composed of one rotary drive source, one drive force transmission means (for example, a drive force transmission means with a clutch) that divides the drive force of the rotary drive source into a plurality of parts, and and a plurality of (for example, two) driving wheels driven by a divided driving force.

Further, the propulsive force output means 34 is configured by a primary side structure 61 of a plurality of linear motors 6 spaced apart in the lateral direction and driving force transmitted from the rotary drive source spaced in the lateral direction. If the car 3 includes a plurality of drive wheels that generate a driving force for lateral movement by rotating, the car 3 has the lateral track 41 provided with the reaction plate 43 and the lateral track 41 not provided with the reaction plate 43. It is capable of lateral movement corresponding to any of the tracks 41 .

In the configuration of FIG. 11, the propulsion force output means 34 is rotated by the primary side configuration 61 of the plurality of linear motors 6 spaced apart in the horizontal direction and the drive force transmitted from the rotary drive source. and a plurality of drive wheels that generate a driving force for lateral movement, but one of the primary side structure 61 of the linear motor 6 and the drive wheel may be provided in plurality and the other may be provided in one. In this case, adjustment of the driving force of the propulsive force output means 34 located in front or behind the boundary B may be performed only for the plurality of primary side structures 61 or drive wheels.

The elevator of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, some of the configurations of certain embodiments can be deleted.

In the above embodiment, when the forward propulsive force output means 34B in the lateral movement direction of the car 3 exceeds the boundary B, the propulsive force output means 34B forward of the boundary B is driven and The rear propulsive force output means 34A is configured to be stopped. While driving both the thrust output means 34A and 34B, the forward thrust output means 34B, which has already crossed the boundary B, is output from the rear thrust output, which has not yet crossed the boundary B. It may be driven with a driving force greater than that of the means 34A. In this case as well, the car 3 is less likely to be affected by the drop in propulsive force when it crosses over the boundary B, so that the magnetic circuit of the linear motor 6 is divided by the gap at the boundary B so that the car 3 can move smoothly. Since the problem of not being able to move hardly occurs, the car 3 can be smoothly laterally moved between the parallel elevator drive devices 4A and 4B. In this case, from the state where all of the propulsive force output means 34 have not crossed the boundary B, until the car 3 laterally moves and all of the propulsive force output means 34 crosses the boundary B, the backward propulsion The propulsive force of the force output means 34A may be gradually decreased, and the propulsive force of the forward propulsive force output means 34B may be gradually increased, so that the car 3 can be laterally moved more smoothly.

In the above embodiment, the linear motor 6 has the primary side structure 61 provided in the car 3 and the secondary side structure 62 provided in the elevation drive device 4. However, the primary side structure 61 is provided in the elevation drive device. 4 and a secondary arrangement 62 may be provided in the car 3 .

In addition, in the above-described embodiment, the linear motor 6 has two primary side structures 61, but may have three or four or more primary side structures 61. FIG. For example, even when three primary side components 61 (thrust force output means 34) are provided, if all of the plurality of thrust force output means 34 do not cross the boundary B, the lateral direction of the car 3 The driving force of the propulsive force output means 34 which is the most forward in the movement direction is driven so as to be smaller than the driving force of the other propulsive force output means 34 . Further, in a state in which some of the plurality of propulsive force output means 34 have crossed the boundary B, the driving force of the propulsive force output means 34 forward of the boundary B drives the propulsive force output means 34 rearward of the boundary B. driven to be greater than the force.

It should be noted that the linear motor that generates the thrust for lateral movement may not be formed across the car 3 and the lift drive device 4. In this case, the thrust for the lateral movement is provided by the rotary drive source It may be generated by an in-wheel motor integrated with the drive wheel, or by a motor separate from the drive wheel.

In the elevator 1 of the above-described embodiment, two or more sets of the car 3 and the lift drive device 4 are arranged side by side in the horizontal direction. One or more lateral moving units may be arranged laterally parallel to the lift drive device 4 . The moving part comprises a lateral track extending laterally. Also, the linear motor 6 is formed over the car 3 and the lateral movement portion. The arrangement 62 on the secondary side of the linear motor 6 is provided, for example, in the lateral movement. The lateral movement part is, for example, a lateral movement path extending horizontally adjacent to the hoistway 2 .

When the elevator driving device 4 and the lateral moving unit are arranged in parallel, the car 3 moves laterally along the lateral track, thereby moving from the lateral track 41 of the elevator driving device 4 to the lateral track of the lateral moving unit. can migrate. Further, the plurality of propulsive force output means 34 are arranged so that all of the plurality of propulsive force output means 34 are arranged on the basis of the boundary B between the elevation drive device 4 and the lateral movement unit when they are arranged side by side in the lateral direction. In the state where B is not exceeded, the driving force of the propulsive force output means 34 which is the most forward in the lateral movement direction of the car 3 is driven so as to be smaller than the driving force of the other propulsive force output means 34. part of the propulsive force output means 34 has crossed the boundary B, the driving force of the propulsive force output means 34 in front of the boundary B is greater than the driving force of the propulsive force output means 34 behind the boundary B It is configured to be driven to grow.

When two laterally moving parts are arranged in parallel, the car 3 can move between the lateral tracks of the two laterally moving parts arranged side by side. Further, the plurality of propulsion force output means 34 are arranged to move the car 3 in the lateral direction with the boundary B between both laterally moving parts as a reference, and in a state where all of the plurality of propulsion force output means 34 do not exceed the boundary B. The driving force of the propulsive force output means 34 that is the most forward in the direction is driven to be smaller than the driving force of the other propulsive force output means 34, and some of the plurality of propulsive force output means 34 have crossed the boundary B. is configured such that the driving force of the propulsive force output means 34 in front of the boundary B is greater than the driving force of the propulsive force output means 34 behind the boundary B. FIG.

Even in such a configuration, the linear motor 6 does not easily cause the problem that the magnetic circuit is divided by the gap at the boundary B and the car cannot move smoothly laterally. The car can smoothly laterally move between the two laterally moving parts when they are laterally aligned, or between both laterally moving parts when two laterally moving parts are laterally aligned.
