Description: TECHNICAL FIELD The present invention relates to an elevator apparatus.

[Conventional technology]

2. Description of the Related Art Conventionally, an elevator apparatus attached to a building or the like includes an elevator shaft provided along a vertical direction of the building, and a cage for accommodating a user. The cage is suspended in the elevator shaft by a wire cable, and is lifted and lowered in the elevator shaft by winding and pulling out the wire cable, and moves vertically to the floor where the call was made by the user to move the user. Transport.

However, the conventional elevator apparatus cannot accommodate a plurality of cages in one elevator shaft. For this reason, in order to increase the amount of transport per user per unit time and per unit building area, it is necessary to increase the moving speed of the car or increase the number of elevator shafts. However, the moving speed of the cage is limited, and when the number of elevator shafts is increased, there is a problem that the space in each building floor cannot be used effectively because the use area of each floor of the building decreases. Was.

For this reason, an elevator device in which a plurality of cages are movably accommodated in an elevator shaft formed in a loop shape by connecting the upper end and the lower end of each of an ascending route and a descending route with an upper passage and a lower passage. (See Japanese Patent Application Laid-Open No. 62-275987). In this elevator apparatus, each car moves along the elevator shaft as follows and circulates in a loop. .

That is, an endless wire driven by a motor is provided on the ascending route along the ascending route, and the cage sandwiches the wire and ascends in the ascending route. The upper passage is provided with a monorail along the upper passage, and the cage engages with the extendable arm on the monorail and moves in the upper passage by a chain driven by a motor. A guide rail and an endless wire are provided on the descending route similarly to the ascending route, and the cage clamps the wire and descends in the descending route. In addition, the cage moves by itself on the descending route. It is stated that this makes it possible to accommodate a plurality of elevator cars in the elevator shaft, to increase the amount of transport per user per unit time, and to make effective use of the space in the building.

[Problems to be solved by the invention]

However, in this elevator apparatus, the method of moving the cage differs between the ascending and descending routes, the upper passage, and the lower passage. For this reason, complicated control is required when the cage moves to the adjacent passage by changing the moving direction. For example, when the cage moves from the ascending route to the upper passage, stop the pinching of the wire at the top of the ascending route, activate the brake to stop the movement, engage the arm with the monorail, and apply the brake. It was necessary to control the operation of canceling the operation of and starting the movement by the chain.

The present invention has been made in view of the above-described facts, and has as its object to obtain an elevator apparatus in which a moving direction of a car can be easily changed.

[Means for solving the problem]

In order to achieve the above object, an elevator apparatus according to the present invention provides a cage passage including a plurality of elevating passages and a traversing passage communicating between the elevating passages, a first rail and a second rail. The longitudinal direction of each rail is aligned with the longitudinal direction of the elevating passage, and the ends of each rail are arranged to face each other at a predetermined interval, and the cage is raised and lowered along the elevating passage. A guide rail for ascending and descending, and a first rail and a second rail, wherein the longitudinal direction of each rail coincides with the longitudinal direction of the traversing passage, and the ends of the rails are spaced apart from each other by a predetermined distance. A traversing guide rail disposed so as to be opposed to each other and guiding the cage in the horizontal direction along the traversing path; a rotating rail rotatably disposed within the space; and both ends of the rotating rail Is a lift A first position facing the ends of the first and second rails of the trail, and a second position where both ends of the rotating rail face the ends of the first and second rails of the traversing guide rail, respectively. And stopping means for stopping the rotation of the rotating rail.

[Action]

According to the present invention, since the rotating rail is stopped at the first position, both ends of the rotating rail face the ends of the first and second rails of the elevating guide rail, respectively. It is possible to move the distance between the first rail and the second rail in the ascending and descending directions. Further, in a state where the rotating rail is stopped at the second position, both ends of the rotating rail face the ends of the first and second rails of the traversing guide rail, respectively. The distance between the first rail and the second rail can be moved in the horizontal direction.

Therefore, if the rotating rail is rotated to stop at the first position or the second position in a state where the cage reaches the position of the rotating rail, the moving direction of the cage is changed. For example, when the cage moves up the elevating passage along the elevating guide rail and moves into the traversing passage, the rotating rail is moved from the first position to the second position when the cage reaches the position of the rotating rail. Rotate. Thereby, since the respective ends of the rotating rail and the traversing guide rail face each other, the moving direction of the cage is changed, and the cage can be moved along the rotating rail and the traversing guide rail stopped at the second position. Become.
As described above, in the present invention, it is possible to change the moving direction of the cage by rotating the rotating rail, so that it is easy to change the moving direction of the cage.

When an AC current is applied to the AC voltage 32, the rotating rail 21 rotates in the direction of arrow A in FIG.

Support portions 42 are attached to the upper and lower ends of the cage 18 for accommodating the occupant, respectively (see FIG. 2). As shown in FIG. 3, a holding portion 44 is rotatably supported by each support portion 42. The holding section 44 rotatably supports a pair of rollers 46 arranged at a predetermined interval. The pair of rollers 46 sandwich the elevating guide rail 20, whereby the cage 18 is guided by the elevating guide rail 20 and can move in the elevating passage 14 in the ascending and descending directions. . When the rotating rail 21 rotates with the pair of rollers 46 at the positions shown in FIG. 3 and the cage 18 stops, the pair of rollers 46 rotates together with the holding rail 44 and the rotating rail 21 integrally. As a result, the cage 18 is guided by the traversing guide rails 22 and can traverse the traversing passage 16.
Further, as shown in FIG. 4, the holding portion 44 is a pair of auxiliary rollers.

The movement of the cage 18 is guided.

As shown in FIGS. 2 and 5, an electromagnet 50 is mounted between the two elevating guide rails 20, and a plurality of electromagnets 50 are provided along the entire length of the elevating passage 14. ing. An elevating magnet 52 composed of a permanent magnet is also attached to the cage 18 corresponding to the electromagnet 50. The electromagnet 50 and the elevating magnet 52 are held at predetermined intervals by the elevating guide rail 20. Thus, the electromagnet 50 and the elevating magnet 52 are connected to each other by using the electromagnet 50 as a primary side.
A secondary motor is used as a lifting / lowering linear motor 54 (see FIG. 6). When an AC voltage is applied to the electromagnet 50 and an AC current flows, the motor operates as a synchronous linear motor, and the controller 40 operates the synchronous linear motor. Is controlled. Control device
By controlling the magnitude and frequency of the AC current flowing through the electromagnet 50 by the 40, the cage 18 moves in the ascending and descending directions in the elevating passage 14, and the movement is stopped. At the time of controlling the descending speed of the cage 18 and at the time of stopping the movement, regenerative control is performed in which the linear motor 54 for raising and lowering acts as a generator to convert the kinetic energy of the cage 18 into electric power and return it to the power supply system.

Further, as shown in FIG. 5, a plurality of electromagnets 56 are arranged along the traversing passage 16 near the traversing guide rail. The cage 18 also has a transverse magnet corresponding to the electromagnet 56.
58 are attached (see also FIG. 2). The electromagnet 56 and the traversing magnet 58 are held at predetermined intervals by the traversing guide rail 22. Thus, the electromagnet 56 and the traversing magnet 58 constitute a traversing linear motor 60 (see FIG. 6), and its operation is controlled by the controller 40. Control device

As shown in FIG. 2, a lifting passage is provided near the electromagnet 50.
A power supply line 64 is provided along 14. The cage 18 has a current collecting shoe 66 corresponding to the power supply line 64 and corresponding to the power supply line 64.
(See FIG. 5). The cage 18 is supplied with power from a power supply line 64 via a current collection
It is used for the operation of the illumination inside the motor 18 and the motor (not shown) for opening and closing the door 68. An information cable 70 is provided near the electromagnet 50 along the elevating passage 14. The information cable 70 is formed of a leaky coaxial cable, radiates a signal being transmitted to the surroundings as a leak magnetic flux, and receives a signal described later from the cage 18. An antenna 72 for receiving a signal leaked from the information cable 70 is attached to the cage 18 in correspondence with the information cable 70, thereby enabling communication between the inside and outside of the cage 18 and the cage 18
Is detected.

As shown in FIG. 6, the information cable 70 is connected to the control device 40. The position information of each cage 18 detected via the information cable 70 is input to the control device 40. In the cage 18, an operation panel 74 operated by an occupant and a sensor 76 for detecting the presence or absence of an occupant in the cage 18 are provided.
And a transmitting device (not shown) are attached. The sensor 76 includes, for example, an infrared sensor that emits infrared rays to detect the presence or absence of an occupant. When the occupant operates the operation panel to specify the destination floor, the destination floor is transmitted as a signal from the transmission device described above and input to the control device 40 via the information cable 70. Further, the output signal of the sensor 76 is also input from the transmitting device to the control device 40 via the information cable 70.

A call button 78 for a user of the elevator apparatus to call the cage 18 is attached to a waiting space on each floor. Each call button 78 is connected to the control device 40. The control device 40 detects the call of the cage 18 from the user by operating the call button 78.

 Next, the operation of the present embodiment will be described.

In the elevator apparatus of the present embodiment, as shown in FIG.
Different cages 18 are operated at work (for example, 8:00 am to 9:30 am), at lunch (for example, 00:00 to 1:00 pm), and during off hours (other than the above). .
In FIG. 7, “○” indicates a floor where the cage 18 stops.

When going to work with the largest number of users who move from the ground floor to the other floor with the highest concentration of users, two of the four elevating passages 14 (Nos. 1 and 2 in FIG. 7) are used. It is for low-rise (1st floor to 10th floor) and has two lift passages (No.3,
4) is for high floors (11th to 18th floors). In the low-rise aisle, the gauge 18 raises the user up to the tenth floor on the first floor of the No. 2 elevating aisle 14 and unloads passengers on each floor. When the passenger unloads on the 10th floor, the cage 18 moves to the No. 1 ascending / descending passage 14 via the 10th floor traversing passage 16 and
After descending to the floor, N
It moves to the elevating passage 14 of o.2 and circulates. In the high-rise aisle, the cage 18 ascends with a user having a destination of 11 or more floors on the first floor of the No. 4 elevator aisle 14. 10 from the second floor
Passengers are dropped off on the 11th and higher floors without stopping the cage 18 as an express section up to the floor. When all the passengers are unloaded on the 18th floor, the cage 18 traverses the traversing passage 16 on the 18th floor, moves to the No. 3 ascending and descending passage 14 and descends to the first floor above the ground.
It moves again to the No. 4 ascending / descending passage 14 via the floor traversing passage 16 and circulates. The elevator apparatus of the present embodiment has ten cages 18, and circulates five cages 18 in each of the low-rise circulation path and the high-rise circulation path. Thereby, the transport amount of the user per unit time and per unit area of the building is improved as compared with the conventional case.

At lunch time, many users move from each floor to the third floor, which is used as a dining room. For this reason, as in the case of going to work, the two elevating passages 14 are for low-rise, the two elevating passages 14 are for high-rise, and the cage 18 can be moved in the traverse direction on the third floor. User cages 18 from floors below
If there is no call and there is no passenger who designates a floor below the third floor as a destination, the cage 18 is moved in the transverse direction on the third floor.

Although the number of users is small during off-peak hours, the direction of travel and the destination floor of users are more random than at work and at lunch. For this reason, for example, two cages 18 are allocated to the No. 1 elevating passage 14, and N cages are used for the low-rise and the high-rise, respectively.
It reciprocates in the elevator passage 14 of o.1. No.2 elevator passage 1
For example, one cage 18 is allocated to 4 and stopped at each floor from the first floor to the 18th floor, and reciprocated in the No. 2 elevating passage 14. For example, two cages 18 are allocated to the elevating passages 14 of No. 3 and No. 4, circulating between the first floor and the 18th floor and traversing on the 10th floor in response to a call from the user. By moving, the cage 18 can be operated according to the moving direction of the user and the destination floor. The surplus cage 18 can be stored on the 19th floor and the first basement floor.

The control device 40 controls the movement of each cage 18 based on the position information of each cage 18 input via the information cable 70 so that the distance between the cages 18 does not become less than a predetermined value.

Next, control for moving each cage 18 to the target floor will be described with reference to the flowchart of FIG.

In step 100, it is determined whether or not the cage 18 has been moved in the traversing direction in the movement path for moving the cage 18 to the target floor. If it is determined that there is no movement in the traverse direction, the linear motor 54 for elevation is operated in step 116,
The cage 18 is moved upward or downward to stop at the target floor.

If it is determined that there is movement in the traverse direction, step 10
The cage 18 is moved to the traversable floor in 2 and stopped at the connection between the cage 18 elevating passage 14 and the traversing passage 16 by the elevating linear motor 54 and the brake device 62. In this state, each roller 46 corresponds to the rotating rail 21 and the rotating rail
Hold 21. In step 104, the rail rotation linear motor is operated, and the rotation rail 21 is moved to the traversing guide rail 22.
To correspond to. Along with this, the roller 46 attached to the cage 18 rotates about the holding portion 44, and the cage 18 can be moved in the transverse direction. When the rotating rail 21 rotates, the brake device 62 corresponding to the elevating guide rail 20 is retracted to the cage 18 side. The brake device
62 is attached to a holding portion 44 that supports a pair of rollers 46 so as to be rotatable integrally with the holding portion 44. When the brake device 62 is operated, the vicinity of a portion of the guide rail that is sandwiched by the pair of rollers 46 is a brake shoe. May be pinched. This allows the brake device to rotate when the rotating rail 21 rotates.
It is not necessary to retract the cage 62, and the cage 18 can be stopped by sandwiching the traversing guide rails 22 when the cage 18 traverses.

At step 106, the presence or absence of an occupant in the cage 18 is determined. If there is an occupant in the cage 18, the traversing linear motor 60 is operated in step 108 to accelerate so that the maximum value of the acceleration applied to the cage 18 becomes small, and decelerate so that the maximum value of the deceleration becomes small. Control is performed so as to stop at the target elevating passage 14. As a result, the acceleration applied to the cage 18 draws a gentle sine curve as shown in FIG. 9 (A), and does not cause discomfort to the occupants in the cage 18. In FIG. 9, the solid line indicates a change in the moving speed of the cage, and the dotted line indicates a change in the acceleration applied to the cage. If there is no occupant in the cage 18, the linear motor for traverse is operated at step 110, The control is performed so that 18 accelerates at a large acceleration, moves to the target elevating passage 14, and stops at a large deceleration. As a result, a large acceleration is instantaneously applied to the cage 18 as shown in FIG. 9 (B), and the time required to move in the traversing passage 16 is reduced as compared with the case where there is an occupant in the cage 18. be able to.

When the cage 18 moves to the target elevating passage 14 and stops, in step 112, the linear motor 38 for rail rotation is rotated.
Is operated to rotate the rotating rail 21 to a position corresponding to the elevating guide rail 20. In step 114, the elevator linear motor 54 is operated to move the cage 18 in the ascending or descending direction and stop at the target floor.

As described above, in this embodiment, ten cages 18 are accommodated in the elevator shaft 12 composed of the four elevating passages 14 and the traversing passages 16 connecting the elevating passages 14. In addition, the transport amount of the user per unit time and per unit area of the building can be improved, and the space in the building 10 can be effectively used.

Further, since the cage 18 is moved by using the linear motor 54 for elevation and the linear motor 60 for traversing, the cage 18 can be moved at high speed, which is effective for high-rise building and the like.

Furthermore, since the rotating rail 21 can be connected to the elevating guide rail 20 or the traversing guide rail 22, and the roller 46 is also rotated together with the rotation of the rotating rail 21, the moving direction of the cage 18 can be changed. Easy.

Further, when the presence of the occupant in the cage 18 is detected, the vehicle is accelerated with a smaller acceleration than when the absence of the occupant is detected and moves in the traversing passage 16, so that the occupant is uncomfortable. The cage 18 can be traversed without giving, and when the absence of the occupant is detected, the traversing is completed in a short time, so that the transport amount of the user per unit time and per unit area of the building can be improved. .

In the elevator apparatus of this embodiment, the lifting linear motor 5 is a so-called one-sided synchronous linear motor constituted by a pair of an electromagnet 50 and a lifting magnet 52. It is not limited.
For example, as shown in FIGS. 10 and 11, a so-called double-sided type in which the elevating linear motor 54 is constituted by a stator 51 attached to the cage 18 and a pair of electromagnets 49 arranged so as to sandwich the stator 51 therebetween. May be used as the induction type linear motor. No.
In the elevator apparatus shown in FIG. 10 and FIG.
Three elevating guide rails 20 are arranged along 14. Stators 51 are arranged at both ends of the cage 18.
A long hole 51A is provided in the stator 51, and the long hole 51A loosely fits a pin 55 fixed to the cage 18. Further, one end of a damper 53 for moving the stator 51 is attached to the stator 51. The other end of the damper 53 is attached to the cage 18. When the cage 18 moves in the ascending or descending direction, the damper 53 projects the stator 51 from the cage 18 to the position shown by the solid line in FIG.
51 and as a linear motor 54 for lifting and lowering,
When the cage 18 moves in the transverse direction, the stator 51 is moved along the long hole 51A to be housed at the position shown by the imaginary line in FIG. This allows the cage 18 to move in the transverse direction without the stator 51 and the pair of electromagnets 49 coming into contact with each other.

Further, in the elevator apparatus of the present embodiment, the elevator shaft 12 is configured in a plane, but the elevator shaft 80 may be configured in a three-dimensional manner as shown in FIG. In conventional elevator equipment, it is necessary to make the elevator shaft a shape that extends in the vertical direction of the building,
In a building where the floor area is gradually reduced from the lower layer to the upper layer, the space in the building cannot be used effectively. However, in the elevator device of the present invention, the twelfth
As shown in the figure, the elevating passage does not necessarily have to be continuous in the vertical direction. In this case, the cage rises vertically in the elevating passage 82 to the upper end of the elevating passage 82 (arrow B in FIG. 12), and moves to the elevating passage 84 extending to a higher floor to move up and down. It rises in the passage 84 (arrow C in FIG. 12).
Thus, in the present invention, the cage can move in a so-called zigzag manner in the elevator shaft. Thereby, the space in the building can be effectively used.

Further, in the elevator apparatus of the present invention, the car can be operated as follows. In other words, the elevator shaft 80 shown in FIG. 12 has a space for raising and lowering the cage arranged in four rows and two columns in the lower part as shown in FIG. There is a traversing passage in the space. Elevator shaft 80
Are provided with four openings 86 for getting on and off. The four elevating passages on the side where the opening 86 is provided are slow lanes for the cages stopping on each floor to go up and down, and the four elevating passages on the side where the opening 86 is not provided are provided on each floor. It is an express lane for a cage that does not stop moving up and down.
The cage can move between the slow lanes (the direction of arrow D in FIG. 13) and can move between the slow lane and the express lane (the direction of arrow E in FIG. 13). When the car that is moving up the express lane unloads passengers, it moves sideways and moves to the slow lane (the direction of arrow F in FIG. 12). The cage in the slow lane descends traversing the slow lane (arrow G in FIG. 12).
direction). When the cage in the slow lane moves to a higher layer, it moves sideways to the express lane and rises (in the direction of arrow H in FIG. 12). As described above, in the present invention, a plurality of passages can be used for the express lane and the slow lane in a shared role, and an opening for getting on and off may not be provided for each passage.

In this embodiment, the rotating rail 21 is rotated by the rotating linear motor 38. However, the rotating rail 21 need not be rotated by a linear motor, and a normal motor or a driving device such as a hydraulic device may be used.

Further, in the present embodiment, a leaky coaxial cable was used as a means for transmitting information between the inside and the outside of the cage 18,
The present invention is not particularly limited to this. For example, a carrier wave such as an electromagnetic wave is modulated by a signal wave containing each information and radiated, and the information is transmitted by a so-called wireless communication that demodulates and extracts a signal on the cage 18 side. You may make it.

In this embodiment, the number of cages is set to 10, and the number of guide rails in each passage is set to 4 or 3.
The present invention is not limited to these numerical values. For example, the number of guide rails in the passage may be two.

Furthermore, in the present embodiment, the linear motor for lifting and lowering is a synchronous type, the electromagnet 50, the lifting and lowering magnet 52 as a permanent magnet,
However, the configuration of the lifting linear motor 54 is not particularly limited to this. For example, a lifting magnet 52
Instead, an induction type linear motor using an iron plate coated with aluminum may be used, or a synchronous type linear motor using an electromagnet instead of the permanent magnet may be used. Similarly, for the traversing linear motor 60, an iron plate or an electromagnet coated with aluminum may be used for the traversing magnet 58. As described above, in the present invention, it is possible to use either the induction type or the synchronous type as the type of the lifting linear motor 54 and the traversing linear motor 60.

In this embodiment, the elevating passage is formed to extend in the vertical direction, and the traversing passage is formed to extend in the horizontal direction. However, in the present invention, the direction of each passage is limited to the vertical direction and the horizontal direction. For example, each passage may be formed to extend obliquely, or may be formed so that the direction changes at an intermediate portion of the passage.

〔The invention's effect〕

As described above, in the present invention, both ends of the rotating rail face the first and second ends of the elevating guide rail, respectively, and both ends of the rotating rail correspond to the traversing guide rail. Since the rotation of the rotating rail is stopped at the second position opposing the ends of the first rail and the second rail, it is possible to easily change the moving direction of the cage. Have.
