DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of operating a self-propelled elevator driven by a linear motor without using a suspension rope.

[0002]

2. Description of the Related Art In recent years, a self-propelled elevator that raises and lowers a car by driving a linear motor has been proposed in place of the conventional rope type elevator. For example, Japanese Unexamined Patent Publication
No. 261789 and JP-A-3-272987.

[0003] In these, a primary coil of a linear motor is provided on the inner wall of a hoistway, a secondary conductor is provided on a car side, and a plurality of units are used by utilizing the interaction between the primary coil and the secondary conductor. In this configuration, the cars are moved up and down in the hoistway.

[0004] In such a self-propelled elevator driven by a linear motor, the present applicant has further developed and proposed the following automatic elevator as a promising one from the viewpoint of reality.

[0005] In this method, first, primary coils of a linear motor are provided on both left and right outer sides of a doorway of a car, respectively.
By attaching secondary conductors to the opposite side walls of the hoistway throughout the hoisting path of the car, the car and the hoistway form linear motors on both left and right sides. Configuration.

[0006] The hoistway has an up-only road and a down-only road, and a car ascending the up-only road becomes a down-only road, and a car descending down the down-only road becomes an up-only road. A traversing path for transition is provided at the uppermost part and the lowermost part, so that a plurality of cars can climb up and down by following a loop-like path one after another.

[0007] Further, the ascending and descending exclusive road of the hoistway is configured such that the car has a plurality of hoistway sections each capable of ascending and descending in parallel in the depth direction from the landing doorway, so that the car can be used for passing on and off. This system is capable of securing routes for use, etc., and controlling such that a plurality of cars can arrive at a target floor without being restricted as much as possible by the movements of other cars while selecting these routes as appropriate.

[0008]

By the way, in the above-mentioned proposal, primary coils of a linear motor are provided on both left and right outer sides of a car, and secondary conductors are provided on both side walls in the hoistway opposed to the primary coils. By doing so, thrust is exerted on two cars on the left and right sides of one car to secure the necessary thrust, which is particularly problematic as a self-propelled elevator.

However, with the current linear motor technology, it is still difficult to secure a large thrust, and it is difficult to increase the capacity of the car in order to reduce the weight of the car as much as possible. I will be forced.
For this reason, there is not much problem in a time zone where elevator users are few and dispersed, but it is necessary to secure a large transportation capacity in a time zone where passengers are concentrated such as morning work time and lunch time. This is necessary, and as described above, the transportation capacity of one car is small, so that even if a plurality of cars are efficiently operated, a problem occurs that a large number of passengers cannot be easily handled.

The present invention has been made in view of the above-mentioned circumstances, and its object is to provide a self-propelled type in which a car is moved up and down by driving a linear motor, but the size of the self-propelled car can be increased as necessary, especially during a time when users are concentrated. It is an object of the present invention to provide a self-propelled elevator operation system that secures transportation capacity and does not reduce overall transportation efficiency and service.

[0011]

In order to achieve the above object, a self-propelled elevator operating system according to the present invention provides a self-propelled elevator in which a plurality of cars are moved up and down in an elevator hoistway by driving a linear motor. The hoistway has a plurality of hoistway parts in which at least three elevator cars can respectively ascend and descend in parallel in the depth direction from the landing doorway, and the car can be moved between the hoistway parts before and after the hoistway part by the guide steering mechanism. The car has a car doorway device that opens and closes in conjunction with the landing doorway device when ascending and descending the front hoistway part, and a rear doorway device that maintains a closed state at normal time on the opposite rear surface. When a large amount of passengers are transported, the connecting means connects the car at the front hoistway part and the car arranged to be able to ascend and descend to the hoistway part immediately behind it. In addition to being connected in a state of being raised and lowered together in parallel in the front and rear, the car entrance / exit device of the rear car is opened in conjunction with the rear entrance / exit device of the front car, and the front and rear cars are brought into an internal communication state. In addition, the connecting car moves up and down by using the foremost hoistway part and the hoistway part immediately behind the foremost dedicated area as dedicated zones.

[0012] When a connecting car for transporting a large amount of passengers moves up and down as a dedicated zone using the front hoistway section and the hoistway section immediately behind the connecting car, the other cars are brought close to the connecting car. It is desirable to retreat to the hoistway site on the rear side and preferentially raise and lower the connected car.

[0013] In addition, the connected car for transporting a large amount of passengers rises and descends while stopping on the floor only at the predetermined large transport applicable floor, and the other cars stop landing on each floor while avoiding the connected car. It is desirable to go up and down.

[0014]

According to the self-propelled elevator operation system having the above-mentioned structure, in a time period when the number of elevator users is small, each car is independently and independently raised and lowered by the linear motor drive to transport the passengers. In addition, if it is necessary to secure a large transport capacity such as morning work hours or lunch, the car at the front hoistway part and the car that can be raised and lowered at the hoistway part immediately behind it are connected. In addition to the connection by the means, the car entrance / exit device of the rear car is opened in conjunction with the rear entrance / exit device of the front car, and the front and rear cars are interconnected to each other, thus the connected car is moved forward and backward. Each linear motor is driven up and down together in a connected state in which the internal communication is performed in parallel.

[0015] Thus, a large number of passengers can get into the connecting car from the landing floor at the landing stop floor, and twice as many passengers can be transported at a time as when the car operates alone, so that a large transport capacity can be secured. become. At this time, the front and rear cars are connected to each other while being internally communicated with each other, but since they are individually driven by linear motors, a necessary and sufficient thrust can be obtained and the vehicle can ascend and descend reliably. Moreover, since the connecting car at the time of the large transportation moves up and down as a dedicated zone between the front hoistway part and the hoistway part immediately behind the connecting car, a large number of passengers can be efficiently transported by the connecting car. Become.

At the time of large transportation by the connected car,
Other cars are evacuated to the rear hoistway part due to the approach of the connecting car, and the connecting car is raised and lowered with priority given to the dedicated zone between the foremost hoistway part and the immediately following hoistway part If this is done, more efficient passenger transport will be possible.

[0017] Further, the connected car during the transportation of a large amount of passengers rises and descends while stopping landing only on the predetermined large transport applicable floor (body transport service floor), while the other cars avoid the connected car. If you stop landing on each floor and move up and down, it is possible to perform high-efficiency large transport for many people by connecting cars, and at the same time, you can stop landing according to calls to each floor by other cars. As a result, large transport capacity can be secured without lowering the overall service.

It is supposed to be.

A car doorway device 23 is provided at the front doorway of the car room 21 of each car 2.
The rear entrance device 24 is provided also on the rear surface opposite to this.

The car doorway device 2 on the front of the car 2
Reference numeral 3 includes a pair of left and right doors 23a arranged to be openable and closable at the front entrance of the cab, and a motor-equipped door opening and closing drive mechanism 23b for opening and closing the doors. The engagement plate (3) is configured to protrude forward from the door 23a. The configuration is the same as that of a conventional general car door device having a razor (commonly called a razor) 23c.

When the car 2 stops landing on the destination floor, the drive mechanism 23b operates to open the left and right doors 23a. At this time, the engaging plate 23c is connected to the landing doorway device 15 by the driving mechanism 23b. A door engaging mechanism having a pair of engaging rollers 15b on the back surface of the left and right doors 15a of the left and right doors 15a (similar to a conventional general landing door device) enters between the rollers 15b of the door entrance mechanism 15 and the left and right sides of the landing entrance device 15 thereof. When the car 2 departs from the floor after the passengers get on and off, the doors 23a and 23b are opened in conjunction with each other so as to follow the door 15a.

The connecting device 25 uses mechanical means such as a connecting device of a railway vehicle or an electromagnet. When a large amount of passengers are transported, the car 2 of the front hoistway portion 11a or 12a and the rear hoistway portion 11b are used. Alternatively, it is a configuration in which the car 2 that is arranged to be able to move up and down to 12b is connected in a state of being moved up and down together in parallel in the front and rear.

In the drawing, reference numeral 26 denotes a current collecting device (current collecting shoe) mounted on one side of the cab of the car 2, which slides on a power supply line (not shown) provided in the hoistway 1. In contact therewith, it controls the primary coil 17 of the car 2, the car guidance steering mechanism 22, the car entrance / exit device 23, etc., and collects power for power and power for lighting in the car.

Next, the operation of the self-propelled elevator operating system having the above configuration will be described. Normal operation is performed during a time period when there are relatively few elevator users. During this normal operation, each car 2 is separated and independent, and the current collector 26 independently receives power for control and power from the power supply line, and receives the primary coil 17 on both sides of the car room and the two coils on both sides inside the hoistway 1. A thrust is obtained by driving a linear motor to generate a suction / repulsion force with the next conductor 16, and each car 2 moves up and down and stops while being guided by the car guidance steering mechanism 22.

At the time of such normal operation, passengers get on and off by moving the car 2 alone to the front hoistway sections 11a, 12a near the landing entrance 15 of the hoistway 1 or the hoistway 11 of the hoistway 1 alone. Then, the car 2 is stopped at the landing on the floor and the door is opened. Then, the car 2 is raised and lowered to the destination floor in response to the in-car call and the hall call assigned to the car.

When the car 2 travels alone, the foremost hoistway sections 11a and 12a and the corresponding traversing paths 13 and 14 are mainly used, but other cars are provided in the course between the destination floors. If there is a vehicle 2 or if it is determined that such a state will occur, the car guide steering mechanism 22 is operated to bypass them, and the car 2 is moved from the front hoistway sections 11a and 12a. Hoistway section 11 on the rear side
The route is shifted to the overtaking route of b, 12b, returned to the hoistway sections 11a, 12a near the target floor again, and stopped on the target floor. At the time of the detour, it is also possible to move the car 2 to the hoistway portions 11c and 12c on the rear side to operate.

The hoistway sections 11b, 12 on the rear side
b and the hoistway sections 11c and 12c on the rear side are used for orthogonal driving when an empty car 2 with no passengers is forwarded to a specific floor, or when a fault occurs in a certain route and the car cannot be passed. Lines, used as standby lines for excess cars when there are few passengers.

When it is necessary to secure a large transport capacity, such as in the morning at work or during lunch, as shown in the dedicated downhill road 12 in FIG. For the rear surface of the car 2 to be arranged, the rear shaft section 1
The car 2 arranged in 2b is approached while being tilted by the thrust by the linear motor drive and the guidance of the car guidance steering mechanism 22, and joined at the same height in a state in which the car 2 is arranged back and forth.
Then, the two cars 2 and 2 are connected to each other by the connecting device 2.
Connect by 5.

With this approaching operation, the engaging plate 23c of the car doorway device 23 on the front side of the rear car 2 is moved to the rear side of the left and right doors 24a of the rear doorway device 24 of the front car 2 by the door engaging mechanism. It enters between the rollers 24b. In this state, the car entrance / exit device 23 of the rear car 2 opens the door, and the doors 24a of the rear entrance / exit device 24 of the front car 2 are opened in conjunction with each other so as to follow.

With this, the two cars 2 and 2 are lifted and lowered together by the linear motor drive in a connected state in which the two cars 2 and 2 are communicated in parallel in the front and rear direction. When the landing is stopped at the landing floor, the car doorway device 23 on the front side of the car 2 on the front side operates the door opening operation in conjunction with the landing doorway device 15.

In this state, the passengers can get into the car 2 on the front side of the connected cars 2 and 2 from the landing, and can also pack the car 2 on the rear side as it is, so that a large number of passengers Now you can get on the car 2
The car entrance / exit device 23 on the front of the vehicle interlocks with the hall entrance / exit device 15 to close the door, and the connected cars 2 and 2 move up and down to the target floor together. As a result, twice as many passengers can be transported at one time as compared with the time when the car 2 operates alone, and a large transport capacity can be secured. At this time, the front and rear cars 2 and 2 are connected to each other by internal communication. However, since they are individually driven by the linear motors, a necessary and sufficient thrust is obtained and the vehicle can ascend and descend reliably.

Moreover, the connecting car 2 for the large transportation
2 moves up and down as a dedicated zone using the front shaft section 12a and the shaft section 12b immediately behind the front shaft section 12a, so that a large number of passengers can be efficiently transported by the connected cars 2 and 2.

In addition, during large transportation by the connecting cars 2, 2, the other cars 2 move to the rear hoistway section 12c and retreat when the connecting cars 2, 2 approach,
The connected cars 2, 2 are moved up and down with priority given to the dedicated zone of the front shaft section 12a and the hoistway section 12c immediately behind, so that more efficient passenger transport can be performed.

Further, the connected cars 2 and 2 during the transportation of a large amount of passengers move up and down while stopping landing on only the preset large transport applicable floor (body transport service floor). The vehicle stops landing on each floor while avoiding the cars 2 and 2, and then goes up and down. At the same time, the connected cars 2 and 2 perform high-efficiency large-scale transportation for many people, and the other cars 2 The landing will be stopped according to the call, and large transportation capacity will be secured without lowering the overall service.
