Description

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 double-deck elevator, and more particularly to a method of operating when demand for transportation is concentrated on a specific floor.

[0002]

2. Description of the Related Art Double-deck elevators that operate by connecting two cars, an upper car and a lower car, are operated by a double system, a single system, and a semi-double system.
A method can be considered. The contents and characteristics of each operation method will be described below.

First, the double system is an operation system in which the upper and lower cars are always stopped on the first floor by stopping the upper car only on the even floors and the lower car only on the odd floors. In this way, the operation of using the upper and lower cars to service the first floor floor jump is a basic operation method of a double-deck elevator, and has a capacity of 2 compared to a general elevator.
In addition to doubling, the number of stops is halved, which shortens the lap time, has high transportation capacity, and has the advantage of shortening the waiting time at the landing. However, in this case, the user needs to use the stairs for one floor for inter-floor movement (inter-floor traffic) such as odd floors to even floors or even floors to odd floors. Therefore, it is necessary to take architectural considerations such as arranging stairs so that they can be used easily.

The single system is a system in which the door of the lower (upper) car of the two upper and lower cars is closed and only the upper (lower) car is used for service like a general elevator.

This system is suitable for handling inter-floor traffic, but one car is not used, so the double-deck elevator cannot be effectively used in terms of transportation capacity and the like.

[0006] Normally, in a double-deck elevator, the specifications such as the number of vehicles are set based on the improvement of the transportation capacity due to the two-story car. Therefore, when operated by the single system, the transportation efficiency drops to about 2/3. , Transport capacity will be insufficient. If the single method is applied to business hours, which occupy most of the daytime, one lap time will be extended, the car operation interval will be longer, and the average waiting time will be longer than the double method. Therefore, the single method is used only when it is applied to passenger transportation where the stairs cannot be used, such as in the off-hours of traffic such as at night or in wheelchair users.

The semi-double system is an eclectic system of a double system and a single system, and it is a system that tries to cope with inter-floor traffic while leaving the advantages of the double system, which is a feature of the double deck elevator, as much as possible.

Basically, a car responds to a hall call like a hall call on an even floor and a lower car responds to a hall call on an odd floor as in the case of the double system, and the upper and lower cars stop on the first floor jump. Let The car call registration method for passengers from the departure floor is the same as the double method. For example, only even floors in the upper car and only odd floors in the lower car are valid. However, after the car leaves the departure floor and is stopped by a landing call, it is possible to register the car calls for all floors without any distinction between even and odd floors.

That is, the passengers on the departure floor are asked to divide the halls according to the odd and even floors and the destination floor, but passengers from the middle floor can directly enter the upper or lower car. You can reach the destination floor without using stairs.
Compared to the double system, the number of car stops increases, the waiting time at the hall and the boarding time of passengers increase, but it is effective for inter-floor traffic.

[0010]

However, to take advantage of the characteristics of the double-deck elevator for the purpose of improving the transportation capacity, the double method is adopted as the basis of the operating method, which can always exert the transportation power to operate on the first floor. However, in the conventional method (double method, single method, semi-double method), if there is only one dining room floor on one floor at any time, there is a demand for elevators at a specific floor at lunch time or at the end of a meeting. If you concentrate on one place, the upper deck (or lower cage) of the double deck elevator may be full, but the lower cage (or upper cage) may continue to operate with almost empty condition. In some cases, it may not be able to fully exert its own transportation capacity, and may only exhibit the same transportation capacity as a single-dish elevator.

Therefore, an object of the present invention is to provide a double-deck elevator which efficiently handles the transportation demand to a specific floor and the demand from a specific floor in a specific time zone.

[0012]

In order to achieve the above object, the present invention provides a double-deck elevator in which a car in which an upper car and a lower car are vertically connected is arranged on one shaft, wherein the upper car and the lower car are arranged. 1 for each
A means to enable service on the floor floor, and service during lunch time or concentrated operation on a specific floor when demand on the cafeteria floor or a specific floor is concentrated. Provide a double deck elevator with means to enable. Further, a display unit is provided for notifying which of the upper car or the lower car is serving at the hall on the dining room floor or the specific floor during the lunch operation or the concentrated operation on the specific floor. In addition, the upper car and the lower car will be equipped with an in-car operation panel that displays whether or not the service floor can be registered.

[0013]

According to the present invention having the above-described structure, in the double-deck elevator in which the upper car and the lower car are vertically connected to one shaft, the upper car and the lower car are serviced on the first floor respectively. During the lunch operation or the concentrated operation on the specific floor where the demand on the dining room floor or the specific floor is concentrated, both the upper car and the lower car are served to the dining room floor or the specific floor. Further, during the lunch operation or the concentrated operation on the specific floor, the display means informs whether the upper car or the lower car is in service at the hall on the dining room floor or the specific floor.
Further, whether or not the service floor can be registered is displayed on the operation panel in the car.
