Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator system.

[Conventional technology]

BACKGROUND ART Conventionally, an elevator apparatus installed in a building or the like includes an elevator shaft provided along the vertical direction of the building, and a cage for accommodating users. The cage is suspended in the elevator shaft by a wire cable, and is raised and lowered in the elevator shaft by winding and pulling out the wire cable, and moves vertically to the floor where the user calls, and carries the user. transport.

However, conventional elevator systems cannot accommodate multiple cages within one elevator shaft. Therefore, in order to increase the amount of transportation carried by users per unit time and per unit area of a building, it is necessary to increase the moving speed of the cage or increase the number of elevator shafts. However, there is a limit to the movement speed of the cage.
Furthermore, when the number of elevator shafts is increased, the effective area of each floor of the building is reduced, so there is a problem that the space within the building cannot be used effectively.

For this reason, the present applicant has proposed an elevator system that is provided with a passageway for going up and down and a passageway for traversing, and in which a plurality of cages go up and down and traverse along each passage (Japanese Patent Application No. 72852/1989).
. This elevator system makes it possible to accommodate a large number of cages in the elevator shaft, increasing the amount of transportation per unit time for users and per unit area of the building, and making effective use of space within the building. .

In the above-mentioned elevator apparatus, a lifting guide rail is arranged along the lifting passage, and a traversing guide rail is arranged along the traversing passage.

A pair of guide rollers are attached to the cage to sandwich the lifting guide rail or the traversing guide rail.
It is guided in the ascending and descending direction or in the transverse direction via guide rollers. Further, a rotating rail is provided at a position where the lifting guide rail and the traversing guide rail intersect, and the rotating rail has a first position where the lifting guide rail is continuous and a second position where the traversing guide rail is continuous. It is possible to rotate between the two positions. When changing the direction of movement of the cage, this is done by rotating the rotary rail in a state where the guide rollers correspond to the rotary rail. This changes the direction of movement of the cage.

[Problem to be solved by the invention]

However, when a plurality of cages are allowed to operate in a single elevator passageway, the transportation capacity of the elevator system may be reduced if there are variations in the floors at which the cages stop.

For example, when a preceding car has many floors to stop, the following car is restricted in its movement speed even if it has fewer floors, and the transportation capacity of the elevator system is reduced.

Further, in the elevator system, when the following car is moved sideways to overtake the preceding car, there is a problem in that the travel time becomes long. That is,
- First, the ascending movement of the following cage is stopped, the rotation rail is rotated to change the direction of movement, and then the cage is moved approximately horizontally in the traversing passage, and when it reaches another elevating passage, the movement is stopped again and the cage is moved. It was necessary to change direction and move upwards. As described above, when the moving route of the cage includes upward and downward movement and movement between the upward and downward passages, the movement time becomes long. For this reason, the waiting time after a car is called becomes long, and as a result, the transportation capacity of the elevator system is reduced.

The present invention has been made in consideration of the above facts, and can shorten the waiting time after calling a cage.
The aim is to obtain an elevator installation with which the transport capacity can be improved.

[Means to solve the problem]

In order to achieve the above object, an elevator apparatus according to the present invention includes a passage including a plurality of lifting passages and a diagonal passage that communicates between the lifting passages, and a passageway provided along the lifting passage. a lifting guide rail, a diagonal guide rail that is arranged diagonally with respect to the lifting passage in the diagonal passage and that connects the lifting guide rails provided in different lifting passages; a driving means for moving the cage along a guide rail and a diagonal guide rail; and a control means for controlling the driving means so that the cage is moved along the elevating guide rail or the diagonal guide rail;
have.

Further, the cage includes a moving part that is moved by the driving part, a housing part that is rotatably supported by the moving part and that accommodates the occupant, and a housing part that is connected to the moving part so that the housing part always faces in a vertical direction. It is preferable to include a rotating means for rotating the parts relative to each other.

[Effect]

In the present invention, a lifting guide rail is provided along the lifting passage, and in the diagonal passage, a lifting guide rail is provided at a diagonal t with respect to the lifting passage and is provided in a different lifting passage. A diagonal guide rail is provided to communicate between the two. The control means controls the cage to move along the elevation guide rail or the diagonal guide rail.

As a result, for example, when multiple cages are operating in a single elevator passageway and the preceding cage has many stopping floors, the following cage can be moved diagonally along the diagonal guide rail to take the lead. Since the car can be overtaken, the transportation capacity of the elevator system can be improved. Additionally, compared to the case where the cage is moved laterally and overtaken, the moving distance of the cage can be shortened, so the waiting time after calling the cage can be shortened, and the cage transportation capacity can be improved. can be done.

In addition, by providing a housing part that is rotatably supported on the moving part moved by the drive part and accommodating the occupant, and by making the storing part always face vertically by the rotating means, the moving part can be used for diagonal travel. Even when the storage part is moved along the guide rail and tilted diagonally, the storage part is rotated relative to the moving part,
The floor surface of the storage section is maintained substantially horizontal. This guarantee prevents the occupant from losing his/her balance when the cage moves in the diagonal direction.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a building 10 equipped with an elevator system according to the invention. The building 10 is provided with an elevator shaft 12 through which a car 18 (described later) of the elevator system moves. The elevator shaft 12 includes four elevating passages 14 extending in the vertical direction of the building 10 and diagonal passages 1 provided at multiple locations along the vertical direction and communicating between the elevating passages 14.
It consists of 6. The cage 18 is a lifting passage 14
It is movable in the ascending direction and descending direction within the diagonal passage 16, and is also movable in the so-called diagonal direction, which is an inclined direction with respect to the ascending and descending direction.

As shown in FIG. 2, two lifting guide rails 20 are installed along the lifting passage 14 in each lifting passage 14. As shown in FIG. The cross section of each lifting guide rail 20 in the direction perpendicular to the longitudinal direction is shaped like a channel in which both end portions of the opening are bent in a direction approaching each other. have.

The cage 18, whose movement is guided in the vertical direction by the vertical guide rail 20, includes a moving section 22 that is moved by applying a moving force, and a housing section 24 that accommodates the occupant. A rotating shaft 26 protrudes from the moving section 22, and the moving section 22 rotatably supports the housing section 24 via the rotating shaft 26. Further, a support shaft 28 protrudes from the surface opposite to the surface from which the rotating shaft of the moving section 22 protrudes. A support portion 30 that is accommodated in the elevating groove portion 21 is attached to the tip of the support shaft 28 . The support portion 30 has a pair of rectangular parallel support plates 32 and 34 fixed to the support shaft 28. A pair of rollers 36 are pivotally supported between the parallel support plates 32 and 34 with a support shaft 28 in between. The radially outer end of each roller 36 is in contact with the inner wall of the lifting guide rail 20. On the outside of the pair of parallel support plates 32 and 34,
A total of four ball bearings 38 are fixed coaxially with each roller 36. each ball bearing 38
are arranged so as to be in constant contact with the inner wall of the elevating groove 21. Thereby, the moving part 22 is guided to move along the lifting guide rail 20, and is supported so that a predetermined gap is maintained between an electromagnetic coil 58 and a permanent magnet 64, which will be described later.

Further, as shown in FIG. 3, a pair of skew guide rails 40 are laid in the skew passage 16 along a skew direction that is inclined with respect to the vertical direction. One end of the diagonal guide rail 40 is connected to the lifting guide rail 20 laid in a predetermined lifting passage 14, and the other end is connected to the lifting passage 14 adjacent to the predetermined lifting passage 14. It is connected to a guide rail 20 for lifting and lowering laid down.

In addition, the diagonal guide rail 40 is the elevating guide rail 2.
0 and has a diagonal groove 42 (
(See Figure 4). This oblique movement groove 42 can accommodate the support part 30 similarly to the elevation groove 21.

As an example, as shown in FIG. 4, a diagonal guide rail 40
At the connecting portion 44 between the guide rail 20 and the lifting guide rail 20, the lifting groove 21 and the skewing groove 42 are communicated with each other. Further, a rectangular hole 46 along the direction that blocks the vertical direction and a rectangular hole 48 along the direction that blocks the oblique direction are bored in the vicinity of the connecting portion 44 of the vertical groove 21. Two slide plates 50.52 are disposed in the connecting portion 44, and the slide plates 50.52 can protrude into or retreat into the elevating groove 21 through the rectangular holes 46.48.

Note that FIG. 4 shows a state in which the slide plate 52 protrudes into the elevating groove 21 and the slide plate 50 is retracted from the elevating groove 21.

Each slide plate 50, 52 has a slide plate drive device 54 (
(see Figure 6).

In the state where the slide plate 50 protrudes into the elevating groove 21 and the slide plate 52 is retracted from the elevating groove 21, the support portion 3
0 moves in the ascending direction from below in the elevating groove 21 and passes through the connecting part 44, the rollers 36 and the like come into contact with the slide plate 50 and are guided in the ascending direction without changing the direction of movement.

In addition, when the slide plate 52 protrudes into the elevating groove 21 and the slide plate 50 is retracted from the elevating groove 21, the rollers 36 and the like come into contact with the slide plate 52 when the support portion 30 passes through the connecting portion 44. The direction of movement is changed to the oblique direction, and the object is guided into the oblique groove 42 . In this manner, by protruding either of the slide plates 50, 52 into the elevating groove 21, the support portion 30 can be guided in the elevating direction or the oblique direction. Each connecting portion 44 is provided with a similar slide plate, so that the moving direction of the support portion 30, that is, the moving direction of the cage 18 can be changed.

Note that a weight 56 serving as a rotating means is attached to the lower end of the accommodating portion 24 of the cage 18.

As a result, even when the support section 30 moves within the skew groove 42 and the moving section 22 is tilted along the skew direction, the accommodating section 24 is rotated relative to the moving section 22 by the weight 56. The floor surface of the storage section 24 is maintained substantially horizontal.

As shown in FIG. 2, an electromagnetic coil 58 is installed between the two lifting guide rails 20 in the lifting passage 14. As shown in FIG. The electromagnetic coil 58 is provided along the entire length of the elevating passage 14, and has a large number of elevating excitation coils 60 arranged along the elevating direction as shown in FIG. As shown in FIG. 6, each lifting excitation coil 60 is connected to a power supply control device 62, and is energized or de-energized by the power supply control device 62. Further, as shown in FIG. 2, the cage 18 is moved 822 in correspondence with the electromagnetic coil 58.
A permanent magnet 64 is attached to the. As aforementioned,
The electromagnetic coil 58 and the permanent magnet 64 are maintained at a predetermined distance by the support portion 30. Therefore, the electromagnetic coil 5
8 and the permanent magnet 64 constitute a driving means, and when a large number of excitation coils 60 for elevating are sequentially energized and excited by the power supply control device 62 along the elevating direction, the cage 18 is moved in the elevating direction. Acts as a motor.

As shown in FIG. 5, electromagnetic coils 58 are also installed between the two diagonal guide rails 40 in the diagonal passage 16, and a large number of electromagnetic coils 58 are arranged along the diagonal direction. It has an excitation coil 66 for diagonal movement. This skew excitation coil 66 is also connected to the power supply control device 62. When the electromagnetic coil 58 and the diagonal excitation coil 66 are sequentially excited along the diagonal direction, they function as an induction linear motor that moves the cage 18 in the diagonal direction.

In addition, a lifting guide rail 20 and a diagonal guide rail 4 are also provided.
An electromagnetic coil 58 is also attached near the connection part 44 with 0, and this electromagnetic coil 58 has a large number of finely divided excitation coils 68 for changing direction. This direction changing excitation coil 68 is also connected to the power supply control device 62 . When moving the cage 18 in the up/down direction to pass the connection part 44, the power supply control device 62 sequentially excites the direction change excitation coil 68 along the up/down direction. In addition, when changing the moving direction of the cage 18 and moving it to the oblique direction using the connecting portion 44, each direction-changing excitation coil is connected so that the moving direction of the cage 18 changes smoothly from the ascending and descending direction to the oblique direction. energize it by energizing it.

As shown in FIG. 6, the power supply control device 62 is connected to the control device 70, and each excitation is controlled so that the cage 18 moves in the movement direction instructed by the control device 70 and at the movement speed instructed by the control device 70. Electrify the coil. Furthermore, when the cage 18 is lowered or stopped moving, regenerative braking is performed by causing the electromagnetic coil 58 to act as a generator, converting the kinetic energy of the cage 18 into electric power by the excitation coil 60 for raising and lowering, and returning it to the power supply system.

As shown in FIG. 2, a power supply line 72 is disposed near the electromagnetic coil 58 along each guide rail. cage 1
A current collection brush 74 that contacts the power supply line 72 is attached to the power supply line 8 in correspondence with the power supply line 72 . Electric power is supplied to the cage 18 from a power supply line 72 via a current collector brush, and is used to operate lighting inside the cage 18, a motor (not shown) for the door 76 (see FIG. 3), and the like.

Further, an information cable 78 is disposed near the electromagnetic coil 58 along each guide rail.

As shown in FIG.
It is connected to the. The information cable 78 is composed of a leaky coaxial cable, and radiates the signal being transmitted to the surroundings as electromagnetic waves, and receives the signal from the cage 18. An antenna 80 for receiving signals leaked from the information cable 78 is attached to the cage 18 in correspondence with the information cable 78 (see also FIG. 2). The control device 70 outputs, for example, information indicating the floor on which the cage 18 is currently located, to the information cable 78, and connects the information cable 78 and the antenna 8.
The information is conveyed via 0.

Inside the cage 18 is an operation panel 8 operated by the occupant.
2 and a sensor 84 that detects the presence or absence of an occupant in the cage 18.
is installed. The sensor 84 includes, for example, an infrared sensor that emits infrared rays to confirm the presence or absence of an occupant. The operation panel 82 is a panel for the passenger to specify the destination floor, etc. When the destination floor is specified, the destination floor is transmitted as a signal from the transmitting device 86 and sent to the control device 70 via the information cable 78. Man-powered.

Further, the output signal of the sensor 84 is also input manually from the transmitting device 86 to the control device 70 via the information cable 78. Also,
Position information of each cage 18 detected via an information cable 78 is also input to the control device 70 . Further, a call button 88 for a user to call the cage 18 is attached to the double-bedded hall on each floor, and each call button 88 is connected to the control device 70. The control device 70 detects a call to the cage 18 from the user when the call button 88 is operated.

Next, as an operation of this embodiment, control for moving each cage 18 will be explained with reference to the flowchart of FIG. 7.

In step 100, it is determined whether there is an instruction to move the cage 18. The cage 18 is instructed to move by operating a call button 88 by the user or by operating the operation panel 82 by an occupant in the cage 18 and specifying a destination floor. If there is no instruction to move the car 18, step 100 is repeated until the car 18 is called or a destination floor is specified.

If there is a movement instruction, a cage to be moved is selected in step 102 according to the movement instruction. In the case of a movement instruction using the call button 88, the cage 18 located near the floor on which the call button 88 was operated is selected. Further, in the case of a movement instruction using the operation panel 82, the operation panel 82 selects the operated cage 18.

In the next step 104, the destination floor of the selected cage is determined and a moving route is set. In the case of a movement instruction using the call button 88, it is determined that the floor on which the call button 88 was operated is the destination floor, and in the case of a movement instruction using the operation panel 82, it is determined that the specified destination floor is the destination floor. . Regarding the method of setting the movement route, for example, a movement route connecting the current position of the selected car and the destination floor is assumed, and the car 18 is set to allow other users to get on and off the car on the assumed movement route. If it is necessary to move between the lifting passages 14, such as when the elevator is stopped, the other lifting passage 14 is moved via the diagonal passage 16.
The assumed moving route is changed so that the moving route is moved to . Furthermore, while passing through the diagonal passage 16, other cages pass through the connecting portion 44 between the diagonal guide rail 40 and the lifting guide rail 20 disposed in the diagonal passage 16. Exclusive control is performed to set the travel route so that no accidents occur.

In step 106, it is determined whether the movement route set in step 104 includes movement in an oblique direction.

If the determination in step 106 is negative, the movement route does not include movement in the oblique direction, and therefore the energization of the excitation coil 60 for raising and lowering the electromagnetic coil 58 is controlled to move the selected cage 18 simply. It is moved to the destination floor in the ascending direction or descending direction within one elevating passage 14.

If the determination in step 106 is affirmative, step 11
At 0, the slide plate driving device 54 is controlled so that the slide plates 50 and 52 provided at the oblique movement location on the movement route move to a position that guides the oblique movement of the cage 18.

As a result, for example, at an oblique location as shown in Fig. 4,
The slide plate 52 protrudes into the elevating groove 21, and the slide plate 50 is retracted from the elevating groove 21.

In the next step 112, energization of the electromagnetic coil 58 is controlled to move the cage 18 to the target floor. That is, the cage 18 is moved to the oblique location by controlling the energization of the excitation coil 60 for raising and lowering the electromagnetic coil 58, and the energization of the direction change excitation coil 68 is controlled at the oblique location to move the cage 18.
To change the direction of movement without stopping. After changing the moving direction, the cage 18 is moved along the diagonal guide rail 40 by controlling the energization of the diagonal excitation coil 66. At this time, the movable part 22 of the cage 18 is tilted along the oblique direction, but the weight 5G rotates the accommodating part 24 relative to the movable part 22, and the floor surface of the accommodating part 24 is maintained substantially horizontal. Therefore, when the cage 18 moves in the oblique direction, the occupant inside the accommodation section 24 will not lose his/her balance. After the cage 18 has moved to the lift passage 14, the energization of the lift excitation coil 60 is controlled again to move the cage 18 up and down within the lift passage 14 to the target floor.

In this way, when the movement route of the cage 18 includes movement in the lifting direction and movement between the lifting passages 14,
Since the cage is moved in the diagonal direction along the diagonal guide rail 40, the moving distance can be shortened compared to the conventional case where the cage is moved horizontally between the elevator passages. , it is possible to shorten the moving time from when the cage 18 is instructed to move until the cage 18 reaches the target floor. Furthermore, since the slide plates 50 and 52 are moved to the position to guide the skew movement of the cage 18 before the cage 18 starts moving, the direction of movement of the cage 18 can be changed without stopping the movement of the cage 18. Therefore, the time required to move the cage 18 can be shortened.

In the next step 114, the slide plate drive device 54 is controlled so that the slide plates 50, 52 return to the position where they guide the cage 18 in the vertical direction.

After executing step 114, the process returns to step 100 and repeats the above process.

Note that the diagonal guide rail 40 is not limited to the arrangement shown in this embodiment, but may be arranged in a loop shape such that the moving direction of the cage 18 is changed by 180°, for example.

Further, in this embodiment, the weight 56 is used as a rotating means, but the housing portion 24 may be rotated so as to face in the vertical direction, for example, by a motor or the like.

Further, the elevator shaft may be provided with a diagonal passage for causing the car to traverse in a diagonal direction and a traverse passage for causing the car to traverse in a substantially horizontal direction.

〔Effect of the invention〕

As explained above, in the present invention, a diagonal guide rail is provided in the diagonal passage, which is arranged diagonally with respect to the lifting passage, and connects the lifting guide rails provided in different lifting passages, and Since the cage is moved along the ascending and descending guide rail or the diagonal guide rail, the waiting time after calling a cage can be shortened, and the cage is not affected by the operation of the preceding cage. This has the excellent effect of shortening the time it takes for the cage to reach the destination floor and improving transportation capacity.
