Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement in a two-door/two-gate elevator that has a door on the front landing and the car, and also has a door on the rear landing and the car. be.

[Prior art]

In a conventional two-door, two-gate elevator, when there are hall calls on both doors and one door is being opened in accordance with priority service, there are many passengers boarding on this door side, and the load detection device detects that the elevator is full. , even though the door was opened to the opposite landing after the door was closed, passengers at the opposite landing were unable to board, and the passenger at the opposite landing was unable to board, creating a severe sense of distrust. Ta. It also caused a huge loss in service time, resulting in a deterioration of the overall service.

[Summary of the invention]

This invention has been made for the purpose of eliminating such drawbacks, and when it is detected that one hall is full during service, if there are no car calls and only hall calls at the opposite hall, a service prevention detection device is activated, The purpose of the present invention is to propose an elevator operating device that can prevent services based on hall calls to the opposite hall, thereby improving the overall service.

The normally open contact of the travel detection relay is closed while the vehicle is traveling and opens when it stops. Reference numeral 9 denotes a priority service determination time relay, which is activated when the elevator stop determination relay is activated and operates after a predetermined time period. 9a is the normally open contact, 10F is the normally closed contact of the time relay for setting the non-interference time for the front door,

4R is the same door control relay for the rear door as above, 14
Ra and 14Rb are the normally open contacts, and 15a and 15b are the normally open contacts of the travel pattern command relay, which are closed when the vehicle starts traveling and open when it enters the door zone of the stop floor.

The above example shows a case where each floor of a four-story building has front and rear landings, and since it is dangerous to open the doors at the same time on floors with doors on both sides, the operation will be described below assuming that the doors are opened alternately.

When the elevator is on the first floor and the doors on both sides are open and a rising landing occurs on the front and rear sides of the third floor, the elevator starts running according to a well-known circuit.

When the elevator arrives a certain distance before the third floor, it is determined to stop, the elevator stop determination relay is energized, its normally open contact 4a is closed, and +-4a-9-
- The priority service determining time relay 9 is energized by the circuit 9 and operates after a certain period of time.

Since there are hall calls on both sides of the third floor, the stop detection relay by the front hall button and the stop detection relay by the rear hall button are energized, and their normally open contacts 2
Fa, 2Ra are closed. As a result, +−2Fa−
The front door priority service detection relay 7F is energized at 6Rb-8a-7Rb-7F--. On the other hand, the rear door priority service detection relay 7R is not energized because the operation of the priority service determination time relay 9 is delayed because it is a time relay and its normally open contact 9a does not close. Therefore, the third floor will be serviced from the front hall.

When the elevator reaches the third floor door zone, the run pattern command relay is deenergized and its normally open contacts 15a, 15b open. However, since the front door priority service detection relay 7F is energized and its normally open contact 7Fa is closed, the rear door control relay 14R continues to be energized without being deenergized. On the other hand, the front door control relay 14F is deenergized and the door opens.

Here, if there are many passengers boarding from the front landing on the third floor and the load exceeds 80%, the full occupancy detection switches 1A and 1B close. When the non-interference time for the front door ends and the normally closed contact 10F of the time relay for setting the non-interference time for the front door closes, the door control relay 14F for the front door switches to +-10F-11F-.
12F-13F-14F-- are energized. Also, the normally open contact 14Fa is closed. As a result, +-
1A-14Fa-3Fa-4b-6F-- energizes the full-occupancy detection relay 6F, and its normally closed contact 6
Fb opens.

Normally, after the front door is closed, that is, when the front car door lock switch is turned, the door opening priority relay for the opposite door is activated and the service side door is opened. If the priority relay is deenergized and the door on the opposite side detects a stop due to a car call or a hall call, the door will be opened.

However, as mentioned above, if the front door is detected to be full and there are no passengers getting off at the rear door level, that is, if there is no car call, even if the door opening service is provided, it is already full and no passengers can board the car. I can't get into it.

In this embodiment, the normally closed contact 6Fb of the front full detection relay 6F is inserted between the rear door priority service detection relay 7R and the elevator control DC power supply +, -, and is open. Priority service detection relay 7R is not energized and its normally closed contact 7
Since Rc is closed, +-7Rc-13R-14
At R--, the door control relay 14R for the rear door continues to be energized and the door does not open.

If the front door is detected to be full, and there is no car call at the rear door but only a hall call, service by hall call at the rear door is blocked. As a result, passengers are not left with a significant sense of distrust, and the loss of operating time can be reduced, resulting in improved overall service.

In the above example, the case where there is a front and rear landing area on each floor in a 4-story building was explained.
It can also be applied to buildings other than one story, and can also be applied when there are front and rear landings only on specific floors. Alternatively, instead of giving priority to opening the front door, priority may be given to opening the rear door, or for each floor, priority may be given to the door on the side where more passengers are expected to get on and off.

〔Effect of the invention〕

As explained above, this invention is equipped with a service blocking detection device that blocks service for calls on the opposite side when the service door side detects that the door is full during door open service. This has the effect that the situation where the service is not open can be avoided, and the overall service can be improved without causing distrust to passengers or loss of service time.
