Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides an elevator device in which a car can be moved laterally between a plurality of elevator passages by means of a traverse passage that communicates between a plurality of elevator passages. Regarding.

[Prior art]

Conventional elevator equipment cannot accommodate multiple cages in one elevator shaft, so in order to increase the amount of transportation per unit time of users and per unit area of the building, it is necessary to increase the moving speed of the cages. Or it is necessary to increase the number of elevator shafts. However, there is a limit to the moving speed of the cage, and if the number of elevator shafts is increased, the usable area of each floor of the building will be reduced, resulting in the problem that the space within the building cannot be used for growth purposes. there were.

For this reason, an elevator system in which a plurality of cages are housed in an elevator shaft that is formed into a loop by connecting the upper and lower ends of an ascending route and a descending route through an upper passage and a lower passage. has been proposed (see Japanese Patent Laid-Open No. 62-275987). Additionally, the applicant has proposed that the cage be raised or lowered by a linear motor, and a plurality of lifting passages are connected by a traversing passage, and the cage is made to traverse via this traversing passage. (-For example, Utility Model Application No. 2-72852). As a result, the amount of transportation carried by users per unit time can be increased, and the space within the building can be used effectively.

[Problem to be solved by the invention]

However, in the conventional elevator system described above, inertial force acts on the occupant during acceleration and deceleration when the car is moving sideways, so the car needs to be at a very slow speed when it starts moving and just before it stops. For this reason, if emphasis is placed on passenger comfort, there is a problem in that the cage cannot be moved efficiently.

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to provide an elevator system that can efficiently move a car while maintaining comfort by alleviating the influence of inertial force applied to an occupant when moving the car.

[Means to solve the problem]

The elevator device according to the present invention is an elevator device that can move a car laterally between the elevator passages by means of a traversal passage that communicates between a plurality of elevator passages, wherein a floor tilting mechanism that tilts the cage with respect to the traverse direction; and a tilt control means that controls the floor tilting mechanism so as to offset inertial force applied to the occupant during acceleration and deceleration of moving and stopping the cage. are doing.

[Effect]

When the cage moves laterally and accelerates or decelerates when stopped, an inertial force acts on the occupant. Here, in the present invention, the floor surface tilting mechanism is operated by the tilt control means to tilt the floor surface of the cage so as to offset the inertial force. That is, for example, the floor surface is inclined so that it faces in the same direction as the direction in which the cage starts moving. This causes the occupant to lean in the direction of movement. On the other hand, since the inertial force acts in a direction that causes the occupant to move (try to stay) in the opposite direction to the moving direction, these directions are opposite directions, and the inertial force cancels each other out.

In this way, by inclining the floor surface according to the inertial force, even if the initial speed of the cage is increased or the cage is suddenly decelerated when stopped, no apparent inertial force is exerted on the occupants, making them comfortable. It is possible to increase the speed of the cage while maintaining its performance.

This stopper 28 restricts the rotation of the rotating rail 21 from a position corresponding to the lifting guide rail 20 shown in FIG. 3 to a position corresponding to the traversing guide rail 22 after rotating 90'. .

A rail 30 formed in an arc shape and an electromagnet 32 formed in an arc shape are arranged around the rotation shaft 24 of the rotation rail 21 with the rotation shaft 24 as the center (see FIG. 3).

Further, when the rotating rail 21 rotates with the cage 18 stopped at the position where the pair of rollers 46 is shown in FIG. Thereby, the cage 18 is guided by the traverse guide rail 22 and can traverse within the traverse passage 16. Further, as shown in FIG. 4, the holding part 44 rotatably supports a pair of auxiliary rollers 48, and when the cage 18 moves in the upward and downward directions, and when the cage 18 moves horizontally, the holding section 44 comes into contact with each guide rail. It is designed to assist in the movement of 18.

As shown in FIGS. 2 and 5, an electromagnet 50 is installed between the two lifting guide rails 20, and a plurality of electromagnets 50 are arranged along the entire length of the lifting passage 14. ing. A lifting magnet 52 made of a permanent magnet is also attached to the cage 18 in correspondence with the electromagnet 50. The electromagnet 50 and the lifting magnet 52 are maintained at a predetermined distance by the lifting guide rail 20. As a result, the electromagnet 50 and the lifting magnet 52 are

By controlling the magnitude and frequency of the voltage applied to the electromagnet 50 by the control device 4O, the cage 18
moves in the ascending and descending directions within the elevating passage 14, and its movement is stopped. Note that when the cage 18 is lowered (and when it stops moving), regenerative braking is performed in which the elevating linear motor 54 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 traverse passage 16 near the traverse guide rail. A traverse magnet 58 is also attached to the cage 18 in correspondence with the electromagnet 56 (see also FIG. 2).

(see FIG. 6), and its operation is controlled by a control device 40. By controlling the magnitude and frequency of the voltage applied to the electromagnet 56 by the control device 40, the cage 18 moves in the traverse direction along the traverse passage 16, and also moves in the traverse direction. will be stopped.

Further, a brake device 62 that protrudes from the cage 18 is attached to the cage 18 (see FIG. 2). The brake device 62 has the role of stopping the movement of the cage 18, and stops the cage 18 by sandwiching the lifting guide rail 20 or the traversing guide rail 22 with brake shoes (not shown).

As shown in FIG. 2, a power supply line 64 is disposed near the electromagnet 50 along the lifting passage 14. cage 18
A current collecting shoe 66 that contacts the power supply line 64 is attached to the power supply line 64 in correspondence with the power supply line 64 (see FIG. 5). Electric power is supplied to the cage 18 from a power supply line 64 through a current collecting shoe 66, and is used to operate lighting inside the cage 18, a motor (not shown) for opening and closing the door 68, and the like. Furthermore, an information cable 70 is disposed near the electromagnet 50 along the lifting passage 14. The information cable 70 is composed of a leaky coaxial cable.1. The signal being transmitted is radiated to the surroundings as a leakage current, and a signal to be described later from the cage 18 is received. An antenna 72 that receives signals leaked from the information cable 70 is attached to the cage 18 in correspondence with the information cable 70. This enables communication between the inside and outside of the cage 18, and also enables communication between the inside and outside of the cage 18. The position is detected.

As shown in FIG. 6, the information cable 70 connects to the control device 40.
It is connected to the. The control device 40 has an information cable 70
The positional information of each cage 18 detected via is input. Also, installed inside the cage 18 are an operation panel 74 operated by the occupant, a sensor 76 for detecting the presence or absence of an occupant inside the cage 18, and a transmitting device (not shown).

The sensor 76 includes, for example, an infrared sensor that emits infrared rays to detect the presence or absence of an occupant. When the destination floor is specified by the passenger operating the control panel,
This destination floor is transmitted as a signal from the above-mentioned transmitting device and inputted to the control device 40 via the information cable 70. Further, the output signal of the sensor 76 is also input manually from the transmitting device to the control device 40 via the information cable 70.

Further, a call button 78 for a user of the elevator device to call the car 18 is installed in the waiting space of each floor. Each call button 78 is connected to a control device. The control device 40 detects the call of the cage 18 by the user when the call button 78 is operated.

Next, the operation of this embodiment will be explained according to the flowchart of FIG.

In step 200, it is determined whether or not the cage 18 is moved in the lateral direction during the movement route for moving the cage 18 to the target floor. If it is determined that there is no movement in the lateral direction, the elevating linear motor 54 is activated in step 234 to move the cage 18 in the ascending or descending direction and stop it at the target floor.

If it is determined that there is movement in the transverse direction, step 20
2, the cage 18 is moved to the floor where it can be traversed, and the cage 18 is stopped at the connection between the 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 clamps the rotating rail 21. In step 204, the linear motor for rotating the rail is operated to rotate the rotating rail 21.
corresponds to the guide rail 22 for traversing. Accordingly, the rollers 46 attached to the cage 18 rotate around the holding portion 44, allowing the cage 18 to move in the transverse direction. In addition, when the rotating rail 21 rotates, the brake device 62 corresponding to the lifting guide rail 20
is retracted to the cage 18 side, and is made to correspond to the traverse guide rail after the rotation of the rotating rail 21 stops.

In step 206, it is determined whether there is an occupant in the cage 18. If there is an occupant in the cage 18, step 208
The traverse linear motor 60 is operated at a predetermined acceleration,
Next, in step 210, the electromagnetic valve 122 is energized so that the floor surface 100 faces in the transverse direction according to the acceleration. By this energization, the inclination angle θ of the floor surface 100 is determined according to the acceleration of the traverse linear motor 60, and the inertial force (in the opposite direction to the traverse direction) exerted on the occupant due to the movement of the cage 18 is canceled. The floor surface 100 is inclined so that a reaction force acts. Here, the gravity applied to the occupant is G, and the inertial force is α
Then, the inclination angle θ is expressed by the following formula.

θ= tan α/G Therefore, as shown in FIG. 9 (A>), the above-mentioned apparent acceleration corresponding to the acceleration due to the transverse movement of the cage 18 is obtained, and these cancel each other out and the acceleration applied to the occupant is The inertial forces will be canceled out.

In Fig. 9, the solid line shows the change in the moving speed of the cage, the dotted line shows the change in the acceleration applied to the cage, and the imaginary line shows the change in the moving speed of the cage.
The appearance due to the slope of 00 shows the change in acceleration above.

In the next step 212, it is determined whether the predetermined speed has been reached, and if the determination is negative, the process returns to step 210 and the inclination of the floor surface 100 is continued. If the determination is affirmative, the process proceeds to step 214 where the vehicle is driven at a constant speed, and then, in step 216, the floor surface 100 is made horizontal. In the next step 218, it is determined whether a predetermined distance has been reached, and if the determination is affirmative, the process moves to step 220 and deceleration is started. In the next step 222, the floor surface 100 is tilted in a direction opposite to the traversing direction in accordance with the acceleration at the time of deceleration (deceleration because it is a negative acceleration).

As a result, the inertial force applied to the occupant can be offset, similar to when the movement is started.

In the next step 224, it is determined whether or not the cage 18 has stopped. If the cage 18 has stopped, the process moves to step 226, where the floor surface 100 is made horizontal, and the process moves to step 228.

On the other hand, if there is no occupant in the cage 18, step 230
The traversal linear motor is operated to perform normal transport control. This normal conveyance control includes step 210 and step 2 of the control from step 208 to step 226.
16, the control excludes steps 222 and 226. That is, since there is no occupant, there is no need to change the inclination angle θ of the floor surface 100. Therefore, regardless of the presence or absence of an occupant, the cage 18 can be moved at a large acceleration/deceleration speed, and in the case of an occupant, since the floor surface 100 is inclined, the occupant will not be affected by inertial force. , comfort can be maintained.

When the cage 18 moves to the adjacent lifting passage 14 and stops, the rail rotating linear motor 38 is activated in step 228 to rotate the rotary rail 21 to a position corresponding to the lifting guide rail 20. Step 232
Then, the elevating linear motor 54 is activated to move the cage 18 in the ascending or descending direction and stop it at the target floor.

In this way, in this embodiment, ten cages 18 are accommodated in the elevator shaft 12, which is composed of four lifting passages 14 and a traversing passage 16 that communicates the lifting passages 14. , the amount of transportation of users per unit time and per unit area of the building can be improved, and the space within the building 10 can be used effectively.

Moreover, since the cage 18 is moved using the elevating linear motor 54 and the traversing linear motor 60,
The cage 18 can be moved at high speed, which is effective for high-rise buildings and the like.

Furthermore, since the rotating rail 21 can be connected to the lifting guide rail 20 or the traversing guide rail 22, and the rollers 46 are also rotated as the rotating rail 21 rotates, the moving direction of the cage 18 can be changed. It's easy.

Furthermore, when the presence of an occupant in the cage 18 is detected, the vehicle moves within the passageway 16 at a lower acceleration than when the absence of an occupant is detected, so that the occupant does not feel uncomfortable. The cage 18 can be moved side by side without giving any passengers, and since the car 18 can be moved side by side in a short time when the absence of an occupant is detected, the amount of passengers carried per unit time can be improved.

In the elevator system of this embodiment, the elevating linear motor 54 is a so-called single-sided induction type linear motor composed of a pair of an electromagnet 50 and an elevating magnet 52. However, in the present invention, each linear motor is of this type. It is not limited.

In this embodiment, as the floor tilting mechanism, the plate material 102 is supported by the cylinder 104, and the solenoid valve 122 is turned on and off.
The floor surface 100 was made to be inclined due to the off, but as shown in FIG. As shown, the guide rail 22 for traversing may be inclined depending on the portion of the cage 18 where the acceleration is large.Furthermore, an inclined rail and a horizontal rail may be provided in advance and switched at points.

〔Effect of the invention〕

The elevator system according to the present invention as described above has the excellent effect of being able to efficiently move the car while maintaining comfort by alleviating the inertial force applied to the occupant when moving the car.
