Further, rotating rails 21 are arranged near the upper end and near the lower end of the connection between the elevating passage 14 and the traversing passage 16, respectively.

The rotating rail 21 has an H-shaped cross section similarly to the elevating guide rail 20 and the traversing guide rail 22.
A shaft 24 is supported by a bearing 26 and is rotatable about a rotating shaft 24. The rotating rail 21 corresponds to the elevating guide rail 20 at the position shown in FIG. 3, and corresponds to the traversing guide rail 22 at a position rotated 90 ° from the position shown in FIG.

The pair of rollers 46 sandwich the elevating guide rail 20. Thus, the cage 18 is guided by the elevating guide rail 20 and is movable 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.

By controlling the magnitude and frequency of the voltage applied to the electromagnet 50 by the control device 40, the cage 18 moves up and down in the elevating passage 14, and the movement is stopped. When the cage 18 is lowered (and when the movement is stopped), regenerative braking is performed in which the kinetic energy of the cage 18 is converted to electric power by returning the linear motor 54 for raising and lowering to a 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
By controlling the magnitude and frequency of the voltage applied to the electromagnet 56 by 40, the cage 18 moves in the traversing path 16 in the traversing direction along the traversing path 16 and stops moving in the traversing direction. Is done.

A brake device 62 projecting from the cage 18 is attached to the cage 18 (see FIG. 2). Brake equipment
Reference numeral 62 has a function of stopping the movement of the cage 18, and stops the lift guide rail 20 or the traverse guide rail 22 with a brake shoe (not shown).

In addition, as shown in FIG.
82 are provided. The display unit 82 is configured by sticking a sheet material or the like on which a barcode is printed at a predetermined position on the side surface of the cage 18. The display units 82 are provided in all of the eight cages 18, and the displayed barcodes are different for each cage 18. By reading this bar code, the cage 18 can be identified. A plurality of barcode readers 84 are arranged in the elevating passage 14 along the elevating passage 14. When the cage 18 moves up and down, the display unit 82 displays each bar code reader 84 disposed along the elevating passage 14.
In order. Accordingly, the barcode reader 84 corresponding to the display unit 82 can read the barcode displayed on the display unit 82.

As shown in FIG. 2, a plurality of barcode readers 84 are also provided along the traversing passage 16 in the traversing passage 16. When the cage 18 traverses in the traversing passage 16, the display unit 82 is similarly corresponding to each bar code reader 84 disposed along the traversing passage 16 in order, and the displayed bar code is the bar code reader 84. Is read. Each barcode reader
84 are respectively connected to the control device 40 (see FIG. 6),
The information represented by the read barcode is transmitted to the control device 40.
Output to When the barcode information is input from the barcode reader 84, the control device 40 determines that the barcode reader 84 has detected the presence of the cage 18. It should be noted that each bar code reader 84 is conveniently assigned an address corresponding to the position at which it is arranged, and each bar code reader 84 outputs the bar code information and the address information assigned to itself. The controller 40 stores, in a memory or the like (not shown), a table indicating the correspondence between the address of the barcode reader 48 and the position of the barcode reader 48 to which the address is assigned. The position of each cage 18 can be determined based on the

As shown in FIG. 2, a lifting passage is provided near the electromagnet 50.
A power supply line 64 is provided along 14. A current collecting brush 66 that contacts the power supply line 64 corresponding to the power supply line 64 is provided in the cage 18.
(See FIG. 5). The cage 18 is supplied with power from a power supply line 64 via a current collecting brush 66,
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 current, and receives a signal described later from the cage 18. An antenna 72 for receiving a signal leaked from the information cable 70 and a transmitting device 78 for transmitting a signal toward the information cable 70 are attached to the cage 18 in correspondence with the information cable 70. Thereby, information can be transmitted between the inside and the outside of the cage 18.

As shown in FIG. 6, the information cable 70 is connected to the control device 40. 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 mounted in the cage 18. Sensor 76
Is composed of, 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 transmitting device 78 and the information cable is transmitted.
It is input to the control device 40 via 70. Further, the output signal of the sensor 76 is also input from the transmission device 78 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 a control device. 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 first embodiment will be described.

First, referring to the flowchart of FIG.
Will be described. The interrupt routine of FIG. 7 is started when each barcode reader 84 detects a barcode on the display unit 82, and processes the detected barcode information. In addition, the bar code reader 84, which is in a state where the cage 18 is stopped and the state corresponding to the display unit 82 is maintained, is executed at predetermined time intervals to process the detected bar code information.

In step 200, the cage number is identified from the detected barcode information with reference to the cage management information. The cage management information is stored in the memory of the control device 40, for example, as a table as shown below.

Each cage 18 is provided with a cage number for convenience,
The table stores, for each cage No., cage management information indicating the state of the cage 18 corresponding to the cage No. In the next step 202, the stored detection time and address are read out with reference to the cage management information corresponding to the identified cage No. Note that the detection time and address read at this time correspond to the cage number corresponding to the cage number.
Reference numeral 18 denotes a detection time at the time of previous detection and an address of the detected barcode reader 84.

In the next step 204, the previous address is compared with the current address to determine whether or not there has been a movement from the previous time. If the determination in step 204 is negative, step 2
Move to 10. If the determination in step 204 is affirmative, in step 206, the moving direction of the cage 18 is determined based on the previous address and the current address. In step 208, the moving speed of the cage 18 is calculated based on the elapsed time and the moving distance from the previous detection. In step 210, the cage management information is written in the table, and the process ends.

Through the above processing, the cage management information is updated according to the change in the state of each cage 18, and the state of each cage 18 is grasped.

Next, control when moving each cage 18 using the cage management information will be described with reference to the flowchart in FIG.

In step 250, it is determined whether or not an instruction to move the cage 18 has been given. The movement of the cage 18 is instructed by a call button 78 operated by the user or an occupant in the cage 18 operating the operation panel 74 to designate a destination floor. If there is no instruction to move the cage 18, step 250 is repeated until the cage 18 is called or the destination floor is designated.

If there is a movement instruction, the cage management information stored in the memory is read out in step 252, and the
At 254, the cage 18 to be moved according to the movement instruction is selected. In the case of the movement instruction by the call button 78, the cage 18 located near the floor where the call button 78 is operated is selected based on the read cage management information. When a movement instruction is given by the operation panel 74, the operation panel
74 selects the operated cage 18.

In the next step 256, the destination floor of the selected cage 18 is determined, and a moving route is set. Call button 78
In the case of the movement instruction by the user, the floor on which the call button 78 is operated is determined as the destination floor, and in the case of the movement instruction by the operation panel 74, the specified destination floor is determined as the destination floor. As for the method of setting the moving route, for example, a moving route connecting the current position of the selected cage 18 and the destination floor is assumed, and when another cage 18 is stopped on the moving route, the moving route is traversed. The moving route is set by changing the assumed moving route so as to move to another ascending / descending passage 14 via the moving passage 16. When traversing, the traversing passage 16 where the cage 18 does not currently exist
Set a travel route to traverse via.

In step 258, the address of the barcode reader 84 corresponding to the stop position on the movement route and the address of the barcode reader 84 corresponding to the deceleration start position are obtained. The numbers of the stop positions and the deceleration start positions vary according to the movement route as shown in FIG. 9 as an example. For example, FIG. 9 (A)
As shown in (1), when the moving route to the destination floor is the moving route 86 that only moves down, the stop position and the deceleration start position are each one. Further, as shown in FIG. 9 (B), in the case of the movement route 88 in which the movement route rises after traversing and reaches the destination floor, the stop position and the deceleration start position are each two. Further, as shown in FIG. 9 (C), in the case of the movement route 90 in which the movement route descends, traverses, and descends to reach the destination floor, the stop position and the deceleration start position are each three. In step 258, the address of the barcode reader 84 corresponding to the stop position and the deceleration start position is determined according to the movement route set in step 256.

In the following steps 260 to 274, the cage is moved to the stop position. That is, in step 260, it is determined whether or not the movement of the cage 18 to the stop position is a traversing movement. If the determination in step 260 is affirmative, in step 262 the rotation rate 21 disposed between the current position of the cage 18 and the first stop position is changed to the traversing guide rail 22.
Then, the rotation linear motor 38 is operated so as to correspond to.
On the other hand, if the determination in step 260 is negative, in step 264, the rotating rail 21 disposed between the current position of the cage 18 and the first stop position is moved up and down by the guide rail for lifting.
The rotation linear motor 38 is operated so as to correspond to 20.

In the next step 266, the linear motor 54 for lifting and lowering or the linear motor 60 for traversing is operated, and the movement of the cage 18 to the stop position is started. In the next step 268, it is determined whether or not the cage 18 has reached the deceleration start position. This judgment is
This is performed by determining whether or not the address stored as the cage management information matches the address of the barcode reader 84 corresponding to the deceleration start position. Steps
If the determination at 268 is negative, step 268 is repeated until the determination is positive. If the determination in step 268 is affirmative,
In step 270, the linear motor 54 for elevation and the linear motor 60 for traverse are controlled so that the cage 18 is decelerated at a predetermined deceleration. As a result, the cage 18 is controlled to stop almost at the stop position.

In step 272, it is determined whether the cage 18 has reached the stop position. This determination is made by determining whether the address stored as cage management information matches the address of the barcode reader 84 corresponding to the stop position. If the determination in step 272 is negative, step 272 is repeated until the determination is positive. If the determination in step 272 is affirmative, in step 274, the movement of the cage is stopped.

In step 276, it is determined whether the cage 18 has reached the destination floor. This determination is made by determining whether the position where the cage is currently stopped is the last stop position on the movement route. When there are a plurality of stop positions on the moving route, for example, in the case of the moving routes 88 and 90 described above, this determination is denied and the process returns to step 260, and the cage 18 moves to the next stopping position in steps 260 to 274. To move. If there is only one stop position on the travel route, for example, travel route 86, step 27
When the determination at 6 is affirmative, the process returns to step 250 and repeats the above processing.

It should be noted that characters or numerals may be used instead of the barcode, and these may be read to identify each cage 18.

Further, in the case where the car and the elevator shaft are in one-to-one correspondence with each other as in a conventional elevator apparatus and there is no need to identify the car, the presence or absence of the car is detected instead of the barcode reader 84. A sensor such as an infrared sensor may be used.

Second Embodiment Next, a second embodiment of the present invention will be described. The same portions as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 10, a reflection section 100 is provided on the side surface of each cage 18 of the second embodiment in place of the display section 82 described above. The reflection section 100 has a single projection 104. Protrusion 10
The position where 4 is provided differs for each cage 18 and is offset for each cage 18 along a direction orthogonal to the vertical direction of the cage 18. FIG. 10 shows, as an example, a projection 104 provided at a position corresponding to the cage 18 whose cage No. is “1”. A reflection member (not shown) for reflecting a laser or the like is attached to the lower surface of the projection 104, and constitutes a part of the reflection means.

Further, a reflection section 102 having a single projection 106 is provided on a side surface of each cage 18. The position where the projection 106 is provided is offset for each cage along a direction orthogonal to the transverse direction of the cage 18. FIG. 10 shows, as an example, a projection 106 provided at a position corresponding to the cage 18 whose cage No. is “1”. A reflection member (not shown) for reflecting a laser or the like is attached to a side surface of the projection 106, and constitutes a reflection unit together with the projection 104.

As shown in FIG. 11, a laser processing device 108 is attached to the lowermost portion of each of the four elevating passages 14. As shown in FIG. 10, each laser processing apparatus 108 has the same number of laser processing units 110 as pairs of laser transmitting units and laser light receiving units as the number of cages 18. Each laser processing unit 110 corresponds to the installation position of the projection 104 different for each cage 18 described above. For example, the laser processing unit 110 arranged on the leftmost side in FIG. It corresponds to the installation position. Each of the laser processing units is arranged so that the trajectory of the laser beam transmitted by the laser transmitting unit coincides with the movement trajectory of the projection 104 when the corresponding cage 18 moves up and down in the elevating passage 14, and the elevating passage If there is a corresponding cage 18 in 14, the transmitted laser will
It is adjusted so that it is reflected by the reflecting member of No. 4 and received by the laser light receiving unit.

As shown in FIG. 11, an absorption device 116 is provided at the uppermost portion of the elevating passage 14 in correspondence with the laser processing device 108. The laser emitted from each laser processing unit 110 of the laser processing device 108 is reflected by the projection 104 when the corresponding cage 18 exists in the elevating passage 14, and is absorbed when the cage 18 does not exist. The light enters the device 116 and is absorbed without being reflected or transmitted. Therefore, when the laser is transmitted from each laser processing unit 110, only the laser processing unit 110 in which the corresponding cage 18 exists in the elevating passage 14 receives the laser.

A laser processing device 112 similar to the above is attached to one end of each traversing passage 16, and an absorbing device 118 is attached to the other end. The laser transmitted from each laser processing unit 114 (see FIG. 10) of the laser processing device 112 is reflected by the projection 106 when the corresponding cage 18 exists in the traversing passage 16 and is reflected by the laser light receiving unit. The light is received, and when the cage 18 does not exist, the light enters the absorber 118 and is absorbed without being reflected and transmitted. Accordingly, as described above, when the laser is transmitted from each laser processing unit 114, only the laser processing unit 114 in which the corresponding cage 18 exists in the traversing passage 16 receives the laser.

As shown in FIG. 12, each of the laser processing devices 108 and 112 is connected to the control device 40. The laser processing devices 108 and 112 transmit laser light in a pulsed manner from the laser transmitting units of the laser processing units 110 and 114, and the transmitted laser light
Alternatively, when the laser light is received by the laser light receiving unit after being reflected by the projection 106, information indicating which cage 18 the laser processing units 110 and 114 that have received the laser correspond to the control device.
Output to 40. In addition, the distance to the protrusion 104 or 106 is calculated based on the time from the transmission of the laser to the reception of the laser, and the moving direction and the movement are determined based on the difference between the wavelength of the transmitted laser and the wavelength of the received laser. The speed is calculated and output to the control device 40. The control device 40 controls each cage based on the information input from each of the laser processing devices 108 and 112.
The position, the moving direction, and the moving speed of each cage 18 are determined, and the cage management information is updated. Thus, the control device 40 can always grasp the state of each cage 18 and can control the operation of each cage 18 as in the first embodiment.

As described above, in the second embodiment, the cage is
Since 18 positions are detected, the laser processing devices 108 and 1
There is no need to provide a large number of 12 along the elevating passage 14 and the traversing passage 16.

In the above embodiment, the number of cages is eight. However, the present invention is not limited to this numerical value. For example, the number of cages can be nine or more.

In the second embodiment, the projections 104 and 106 are used as the reflection means. However, a cube corner prism or the like that reflects the laser in the incident direction is used as the reflection means, and the ascending / descending passages 14 and the traversing passages 16 are used. A laser processing unit capable of changing the laser transmission angle may be provided one by one, and the cage 18 may be identified from the reflection angle of the reflected laser.

Further, in the second embodiment, only the position of each cage 18 is detected by the laser. However, information can be transmitted between the cage 18 and the control device 40 by performing laser communication.

Further, when updating the cage management information, the cage 18
The acceleration applied to the cage 18 may be calculated from the moving speed and time of the cage 18 and stored as cage management information, and control may be performed such that the acceleration does not exceed a predetermined value when the movement of the cage 18 is controlled.
