DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is to improve the transportation efficiency by organically combining a self-propelled elevator system installed in the same building and capable of running vertically and horizontally with a plurality of rope-type elevator systems. On possible elevator systems.

[0002]

2. Description of the Related Art Conventionally, most of elevator systems widely used except for a hydraulic elevator which raises and lowers a car using a hydraulic plunger and a winding drum elevator which is used in a relatively small capacity area. In this system, a car and a counterweight are connected in a sloping manner with a rope, and one car is arranged on one hoistway.

[0003] In this elevator system of the hanging type, a car 1 and a counterweight 2 are placed in a hoistway as shown in FIG.
Guide rails (guide rails) 3 and 4 are provided and arranged between them, and both are hanged by a rope 8 via a sheave 6 or a deflecting sheave 7 of a hoisting machine 5 installed in a machine room above the hoistway. It is a configuration to combine in a shape. In recent years, a three-phase induction motor has been widely used as a motor for driving the hoisting machine 5, and an inverter device having a microprocessor mounted on a control device has been widely used.

[0004] In such a lift-type elevator system, a driving force corresponding to an unbalanced load with the counterweight 2 is sufficient except for a running loss caused by a machine for running the car 1. It has a feature that the capacity of the control device can be small, and since it is a system that has been widely used in the past, technology in terms of performance and safety has been established and is reliable.

However, in recent years, as a future prospect,
The idea of a new inter-story transportation system to respond to the demands of skyscrapers has been proposed, but one of the proposed new transportation systems is that the car itself travels without using ropes. This is a concept of a vertically and horizontally movable elevator system having a configuration capable of traveling not only vertically but also horizontally.

The concept of this self-propelled elevator system is as follows:
It breaks down the conventional concept of a single car with one hoistway, and is attracting attention as an innovative technology capable of running a plurality of cars on one hoistway.

FIG. 7 shows the configuration of such a self-propelled elevator system capable of running vertically and horizontally, in which a linear motor secondary conductor 10 is installed in a plurality of cars 9 and provided on a hoistway (elevating shaft). Linear motor primary coil 11
The drive thrust is obtained by the magnetic force between the two. And, as a safety device, a shock absorber 13 for alleviating an impact due to a collision between the brake 12 and the car 9,
In addition, a superconducting magnet 14 is provided inside or below the shock absorber 13 for performing connected traveling. Further, a suspending machine 15 and a movable plate 16 for horizontal traveling are installed on the top floor, and a hydraulic jack 17 is also installed on the lowest floor, and a plurality of cars 9 can travel on one elevating shaft. And

[0008]

However, in the elevator system shown in FIG. 6, generally only one elevator can be installed on one hoistway (elevating shaft). From the viewpoint of the occupied space, it is not preferable in terms of efficiency to take a space of (the cross-sectional area of the elevator shaft per elevator x the number of floors including the express zone), and in particular, the building tends to be high-rise. Today, the trend is becoming more pronounced in higher-rise buildings.

On the other hand, as shown in FIG. 7, in a self-propelled elevator system in which a plurality of cars are run on one elevating shaft, a plurality of cars are mounted on one elevating shaft in comparison with a lift-type elevator system. Since cars can be installed, improvements are expected from the viewpoint of the space occupied by the building.However, in operation management, since there are multiple cars on one elevating shaft, Even if many elevator cars are arranged on one elevating shaft, the time tends to increase from the viewpoint of the waiting time for passengers and the riding time,
It is anticipated that traffic congestion in the elevator car will occur, and operation control will be difficult.

[0010] Further, as compared with the elevator system of the slide type shown in Fig. 6, a large-capacity driving thrust is required and a linear motor primary coil needs to be installed on a hoistway (a hoisting shaft). There is the disadvantage that it increases significantly.

The present invention provides an elevator system capable of improving transportation efficiency, reducing the space occupied by the elevator system in the same building, improving transportation efficiency, and suppressing the equipment cost of the elevator. The purpose is to:

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of an elevator system according to one embodiment of the present invention. In the present embodiment, it is assumed that the building has 31 floors above ground (floor) and 1 basement floor (B1 floor) and has 12 vertically moving shafts, but the present invention is not limited to this. The first and second shafts are provided with first and second self-propelled elevator systems (a self-propelled elevator bank is formed by both systems) for running a car capable of running vertically and horizontally, and are underground. Each of the first floor and the 31st floor has a lateral traveling path on which a car can move in a lateral direction (floor direction).

In each of the first and second self-propelled elevator systems, eight cars are installed in the shaft, the first shaft is a downward operation shaft, and the second shaft is an upward operation shaft. When the eight self-propelled elevator cars depart from the B1 floor, they move up the second shaft, move laterally to the first shaft at the 31st floor, and move laterally again to the second shaft at the B1 floor. , A circulating motion between the first and second shafts is possible. The stop floors of the self-propelled elevator system are B1 floor, 1st floor, 6th floor, 10th floor, 16th floor, 21st floor, 2nd floor as main floors.
The sixth floor and the 31st floor are set, and other than the above are set as express zones so as not to stop.

The third to seventh shafts and the eighth to seventh shafts
The rope-type elevator system shown in FIG. 6 is installed on each of the twelfth shafts, and the rope-type elevator systems respectively installed on the third to seventh shafts are:
Each of them can be moved up and down from the 16th floor to the 31st floor. These five rope-type elevator systems constitute a rope-type high-rise bank, and the rope-type elevators installed on the eighth to twelfth shafts respectively. Each of the systems can be moved up and down from the B1 floor to the 16th floor, and these five rope-type elevator systems constitute a rope-type low-rise bank.

[0022] Accordingly, the passengers from the main floor go from the main floor to the floor near the destination floor by this self-propelled elevator, and change to the rope type elevator at that floor. Conversely, passengers from floors other than the main floor ride on the target rope-type elevator and transfer to the self-propelled elevator at the nearest main floor if there is no destination floor in the bank. In other words, the self-propelled elevator bank is configured to serve only the main floors except the express zone from the B1 floor to the 31st floor in the whole building configuration, and to perform the main transportation function which is the backbone of passenger movement. Then, the group management control is performed for each of the five elevator systems constituting the rope-type low-rise bank and the rope-type high-rise bank.

The major difference between the first embodiment described above and the conventional system is that, when a building of the same scale is assumed, compared with a case where the whole building is constituted by a rope type elevator, a high rise and a low rise Since there are self-propelled elevator banks in each of the banks, the number of groups is reduced by about 2 to 3 units.
Since it is not necessary to use the 15th floor as an express zone, as in the case of a low-rise bank, it is possible to use only elevator equipment that is in the low-speed category of about 120 m / min to 180 m / min. This is beneficial in terms of both cost and equipment cost. In addition, since a driving elevating shaft is not required from the 15th floor to the B1 floor, the building can be used as effective equipment.

FIG. 2 shows a basic circuit configuration for supplying linear motor drive power to the self-propelled elevator bank formed on the first and second shafts of FIG.

The reason for dividing the primary coil 19 into a plurality of sections in this way is that if the primary coil 19 is extended over the entire length of the elevating shaft, a long coil will be used. This is because the economy of the entire system is impaired.

Reference numeral 21 denotes a section selection switch for supplying drive power from each controller 20 to the primary coil (section coil) 19, and the output terminal of each controller 20 is connected via the switch 21 as shown in the figure. It is connected to all section coils 19. Accordingly, the section selection switches 21 for the number of cars can be connected to the respective section coils 19, and for example, the control device 20 of the car 1 of the first car switches the section selection of the section where the car of the first car exists. To select the section coil 19
, And by sequentially selecting the section selection switch 21 according to the traveling direction of the car, the car can be propelled.

That is, assuming that the car of the first car exists in the section a of the first elevating shaft, the control device 20 of the car of the first car firstly operates the section selection switch 21 of 1Aa.

It controls the control device 20 that drives the car 29 by obtaining thrust.

The group management control device 22 includes a hall call control unit 25 and an operation management unit 26. The hall call control unit 25 controls input / output of hall call information from the hall call device 18 for each service floor via the inter-shaft transmission system 27. In addition, the operation management unit 27 includes 1 to 8
Information is transmitted to and from the control device 20 of the car through the inter-control device transmission system 28. Information of each elevator car 29 is input from each control device 20 and each of the elevator cars 29 is input based on the information. While giving a response command to the car 29,
For each car 29, a driving permission command to the next stop scheduled floor and a traversing permission command at the traversable floor (B1, 31st floor in the embodiment of FIG. 1) based on the operation of all the cars 29 and the position situation are given. Output.

Next, the third to seventh shafts and the eighth to first shafts in FIG.
A control system for a two-shaft rope-type elevator (FIG. 6) will be described with reference to FIG. The high / low banks constitute a normal group management system.

According to the above-described embodiment, a plurality of self-propelled elevator systems are installed in a small number of shafts, and only limited main floors are serviced in advance, so that the operation can be managed relatively easily. And can provide backbone transportation to the main floor of the building.

In addition, as a local transportation means for moving from the main floor to the destination floor of the passenger, it is possible to move by a rope type elevator system which performs ordinary group management control, so that the elevator system in the building is occupied. The space required for the elevator can be improved, and the equipment cost of the elevator can be reduced.

In addition, the self-propelled elevator system is configured to serve only the main floor as a main transportation means in the building, and the local elevators that can service each floor from the main floor are constituted by the rope type elevator system, thereby reducing equipment costs. To limit the number of operating elevator shafts to a relatively small number to limit the self-propelled elevator system, which is expensive and difficult to manage the operation of multiple elevators, to the means of transportation to the main floor, thereby reducing equipment costs. And the number of service stop floors is limited, so that operation management can be relatively easily realized.

Further, the rope type elevator system is
Since the main purpose of transportation is to travel only from the main floor,
It is possible to reduce the number of elevator group controls for each bank, and for high-rise banks, there is no need to have an express zone, so relatively low-speed elevator facilities that are comparable to low-rise banks can be used, reducing equipment costs. And the effective floor area in the building can be increased.

Further, since the banks other than the low-rise banks do not have the express zone as in the prior art, the express zone space can be used as an effective floor, so that the effective floor area can be greatly increased.

This embodiment is not limited to the above-described embodiment, and can be carried out in various modifications without departing from the scope of the present invention. For example, in this embodiment, the vertical and horizontal self-propelled elevator has been shown by the demand method by the hall call, but the hall call is eliminated, and each hall is provided with a hall display device for providing arrival guidance and destination floor guidance. Alternatively, each self-propelled elevator may circulate on the top floor / bottom floor with fixed scheduling like a train. In such a case, the passenger can determine the route to the destination floor according to the guidance by the hall display device of the self-propelled elevator hall.

In this embodiment, the self-propelled bank and the rope bank are not linked to each other.
A transfer button is installed in the self-propelled elevator, and if the transfer button is registered a predetermined time before the self-propelled elevator stops at the main stop floor, the hall call of the rope-type local elevator bank is automatically registered and transferred. It is good also as a structure which improves the above usability.

In the embodiment, the rope type elevator is divided into high-rise and low-rise banks, and the self-propelled elevator bank has one shaft each for ascending and descending. However, the present invention is not limited to this. Lift elevator bank /
Two shaft configurations descending and a traversing floor are also provided on the middle floor,
The setting may be such that the floor can be returned halfway according to the elevator demand. Further, the rope type bank is not limited to the two-layer bank configuration, and may be a configuration in which the number of service floors does not match that of the self-propelled elevator bank.

[0048]

According to the present invention described above, the disadvantages of the self-propelled elevator system and the rope type elevator system can be canceled out, and a configuration that organically combines the advantages of each other can be realized in a well-balanced manner. As a result, the present invention can provide an elevator system that can increase transportation efficiency, occupy less space in an elevator system in the same building, improve transportation efficiency, and suppress equipment costs for elevators. .
