Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for operating a self-propelled elevator driven by a linear motor that does not use a hanging rope.

[0002]

2. Description of the Related Art Recently, there has been proposed a self-propelled elevator which moves a car up and down by a linear motor drive in place of the conventional rope type elevator. For example, Japanese Patent Laid-Open No. 2-
There are 261789 and JP-A-3-272987.

In these, a primary coil of a linear motor is provided on the inner wall of the hoistway, a secondary conductor is provided on the side of the car, and a plurality of units are provided by utilizing the interaction force between the primary coil and the secondary conductor. It is configured to raise and lower each car in the hoistway.

The applicant of the present invention has further developed a linear motor-driven self-propelled elevator, and has proposed the following automatic elevator, which can be expected in terms of reality.

First, primary coils of a linear motor are provided on both left and right outer sides of the car, which sandwich the doorway of the car.
Secondary conductors are attached to both side walls inside the hoistway opposite to the car over the entire hoisting stroke of the car, so that the car and the hoistway form linear motors on the left and right sides respectively. It is a composition.

In addition, the hoistway has an ascending path and an ascending path, and a car that has risen on the ascending path is a descending path and a car that descends the descending path is an ascending path. Transverse paths for transition are provided at the uppermost and lowermost portions so that a plurality of cars can move up and down one after another in a looped path.

Further, the ascending / descending path of the hoistway has a plurality of hoistway sections capable of ascending / descending the car in parallel in the depth direction from the entrance / exit of the hall, and is used for getting on / off and passing. It is a system that secures routes such as those for cars and controls them so that multiple cars can arrive at the target floor without being restricted by the movements of other cars as much as possible while selecting these routes in a timely manner.

[0008]

By the way, according to the above-mentioned proposal, primary coils of the linear motor are provided on both left and right outer sides of the car, and secondary conductors are attached to both side walls of the hoistway facing the linear motor. By doing so, thrust is exerted from two places on the left and right sides of one car, and the necessary thrust that is particularly problematic as a self-propelled elevator is to be secured.

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 to be mounted. Therefore, it is necessary to reduce the capacity of the car to minimize the weight of the car. I will be forced.
For this reason, it does not pose a problem in a time when the number of elevator passengers is small and dispersed, but it is important to secure a large transportation capacity in a time when the number of passengers is concentrated, such as work hours in the morning and lunch. This is necessary and, as mentioned above, the number of passengers for a single car is small. Therefore, even if a plurality of cars are operated efficiently, a large number of users cannot be easily handled.

The present invention has been made in view of the above circumstances, and an object of the present invention is a self-propelled type in which a car is lifted and lowered by a linear motor drive. It is 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 operation system according to the present invention is a self-propelled elevator in which a plurality of cars move up and down in an elevator hoistway by a linear motor drive. The hoistway has a plurality of hoistway parts which can be hoisted by at least three cars in parallel in the depth direction from the hall entrance and exit, and the car can be moved between the hoistway parts before and after the hoistway parts by a guide steering mechanism. The car has a car entrance / exit device that opens and closes in conjunction with the landing entrance / exit device when going up and down the foremost hoistway part, and the rear entrance / exit device on the opposite side of the car that maintains a closed state during normal times. When transporting a large number of passengers, the car that is arranged at the front hoistway part and the car that is arranged so as to be able to go up and down immediately behind the hoistway part are connected by the connecting means. The cars are connected in parallel to the front and rear so that they can go up and down together, and the car entrance / exit device of the car on the rear side opens in conjunction with the entrance / exit device on the rear surface of the car on the front side to bring the front and rear cars into internal communication. In addition, the connected car moves up and down by using the foremost hoistway portion and the hoistway portion immediately behind it as a dedicated zone.

[0012] When a connected car for transporting a large number of passengers moves up and down by using the front hoistway part and the hoistway part immediately behind it as a dedicated zone, the other cars are moved by the approach of the connected car. It is desirable to evacuate to the rear hoistway area and to preferentially raise and lower the connected car.

Further, when a large number of passengers are transported, the connected cars move up and down while stopping landing only on a preset floor for large transportation, and the other cars stop landing on each floor while avoiding the connected cars. It is desirable to move 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 passengers of the elevator is small, each car is separated and independently moved up and down by the linear motor drive to transport the passengers. In addition, when it is necessary to secure a large transportation capacity such as during work hours in the morning or during lunch, a car connected to the front hoistway part and a car connected to the hoistway part immediately behind the car can be connected. While connecting by means of means, the car entrance / exit device of the car on the rear side is interlocked with the rear entrance / exit device of the car on the front side to establish internal communication between the front and rear cars, and thus the connected car is connected to the front and rear. In parallel with each other, the linear motors are driven to move up and down together in a connected state in which they are internally communicated.

[0015] With this, a large number of passengers can enter the connected car from the landing stop floor, and it is possible to transport twice as many passengers at a time as compared with the case where the car operates independently, so that a large transportation capacity can be secured. become. At this time, the front and rear cars are connected to each other through internal communication, but since they are individually driven by the linear motors, a necessary and sufficient thrust can be obtained and the car can be surely moved up and down. Moreover, since the connected car during the large-scale transportation moves up and down as a dedicated zone between the front hoistway part and the hoistway part immediately behind it, a large number of passengers can be efficiently transported by the connected car. Become.

Further, during a large transportation by the connected car,
Other cars are retracted to the rear hoistway part by the approach of the connected car, and the connected car is lifted up and down preferentially in the dedicated zone between the front hoistway part and the rear hoistway part immediately behind it. By doing so, even more efficient passenger transportation will be possible.

Further, when a large number of passengers are transported, the connected cars move up and down while stopping landing only on a preset large transportation applicable floor (body transportation service floor), while other cars avoid the connected cars. By stopping landing on each floor and moving up and down, it is possible to carry out highly efficient large-scale transportation for a large number of people with a connected car, and at the same time, stop landing according to calls to each floor with other cars. , It will be possible to secure a large transport capacity without reducing the overall service.

In contact therewith, the primary coil 17 of the car 2, the car guide steering mechanism 22, the car entrance / exit device 23, and the like, and the power supply for the power supply and the electric power for lighting in the car are collected.

Next, the operation of the self-propelled elevator operation system having the above construction will be described. Normal operation is performed during times when the number of elevator passengers is relatively low. During this normal operation, the cars 2 are separated and independent of each other, and the current collectors 26 independently receive power for control and power from the power supply line, and the primary coils 17 on both sides of the car room and the two coils on both sides in the hoistway 1 A thrust is generated by a linear motor drive that generates attraction / repulsive force between the car 2 and the next conductor 16, and each car 2 is moved up and down while being guided by the car guide steering mechanism 22.

During such normal operation, the passengers can get on and off by moving the car 2 independently to the front hoistway portions 11a and 12a near the landing entrance 15 of the ascent road 11 or the ascent road 12 of the hoistway 1. , The car 2 is stopped at the landing on the floor and the door is opened. Then, the car 2 is moved up and down to the destination floor in response to the in-car call and the hall call assigned to the car.

When the car 2 is traveling alone, the front hoistway portions 11a and 12a and the corresponding traverses 13 and 14 are mainly used, but the other car is in the course between the destination floors. 2 is present, 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 parts 11a and 12a. Hoistway part 11 on the rear side
After shifting to the overtaking route of b and 12b, it is returned to the front hoistway parts 11a and 12a near the target floor again and stops landing on the target floor. At the time of the detour, it is possible to move the car 2 to the hoistway parts 11c and 12c on the rear side and operate.

With this, twice as many passengers can be transported at one time as compared to the case where the car 2 operates independently, and a large transportation capacity is secured. At this time, the front and rear cages 2 and 2 are in a state of being internally communicated with each other, but since they are individually driven by the linear motors, a necessary and sufficient thrust can be obtained to surely ascend and descend.

In addition, the connected car 2, when the large transportation
2 ascends and descends using the front hoistway portion 12a and the hoistway portion 12b immediately behind the hoistway portion 12b as dedicated zones, and the connecting car 2, 2 efficiently transports a large number of passengers.

During large transportation by the connected cars 2, 2, when the other cars 2 approach each other, the other cars 2 move to the hoistway portion 12c on the rear side and evacuate,
The connecting cars 2 and 2 are moved up and down preferentially in the exclusive zone between the front hoistway portion 12a and the hoistway portion 12c immediately behind the hoistway portion 12a, so that passengers can be transported more efficiently.

Further, when the large number of passengers are transported, the connected cars 2 and 2 ascend and descend while landing only on the preset large transportation floor (body transportation service floor), and the other cars 2 are connected to the connected car. While avoiding the cars 2 and 2, it stops landing on each floor and goes up and down, so that the connected car 2 and 2 carry out highly efficient large-scale transportation for a large number of people, and at the same time, the other cars 2 reach each floor. Landing will be stopped according to the call, and large transport capacity can be secured without lowering the overall service.

[0044]

Since the self-propelled elevator operation system of the present invention is configured as described above, it is a self-propelled type which elevates and lowers a car by a linear motor drive, and particularly, in view of securing thrust, the capacity of the car is Even when limited to small things, such as during work hours or lunch time when the users are concentrated,

Moreover, the connected car at the time of the large transportation can be connected to the front hoistway part and the rear side immediately behind it. Since the hoistway and the hoistway area are moved up and down as a dedicated zone, a large number of passengers can be efficiently transported by the connected car.

Further, during a large transportation by the connected car,
Other cars are retracted to the rear hoistway part by the approach of the connected car, and the connected car is lifted up and down preferentially in the dedicated zone between the front hoistway part and the rear hoistway part immediately behind it. By doing so, more efficient passenger transportation will be possible, and further, when a large number of passengers are transported, the connected cars will move up and down while stopping landing only on the preset large transportation applicable floor (body transportation service floor). However, by avoiding the connected car, the other cars can be stopped and landed on each floor and moved up and down. By doing so, it is possible to stop landing according to the call to each floor, and it is possible to obtain the effect of securing a large transport capacity without lowering the overall service.
