JPH04125264A - Control device for elevator stop floor - Google Patents

Abstract

PURPOSE:To reduce stopping to one half in the number of times by providing a means which prohibits a cage call for floors upstairs and downstairs to each registered floor for the cage call, and for floors upstairs and downstairs to the floor where a cage is stopped. CONSTITUTION:When a designation button to the fourth floor is depressed, the (b) contacts 13b and 15b of cage call registration relays 13 and 15 are closed, position detecting switches 23 through 25 are also closed, and a relay 14 is thereby actuated, so that a cage call for the fourth floor is kept in a self hold condition. A (a) contact 14a connected to a cage call registration circuit 30 is concurrently closed, so that the cage call is thereby registered. Furthermore, cage call circuits for the fifth and the third floors which are the upstairs and the downstairs of the fourth floor, are closed by the (b) contact 14b of the relay 14, the cage call registration for the third and the fifth floor is thereby prohibited. And when an elevator however reaches the fourth floor, a limit switch 24 is opened, the cage call circuit for the third and fifth floors is thereby opened.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an elevator stop floor control device.

(Prior Art) In elevators that are currently in widespread use, a person riding in a car can freely press a destination floor button to specify the floor where the car should stop.

Therefore, if there are 10 floors to stop, and 10 passengers get off at each floor, the train will start and stop 10 times. This increases the time it takes for the elevator to complete one rotation and return, resulting in a longer waiting time for each passenger.

On the other hand, it is known that the power consumption of an elevator increases in proportion to the number of stops if the load conditions are the same.

Therefore, by rationally processing elevator car calls,
It has become essential to improve elevator service.

(Problems to be Solved by the Invention) If an elevator repeatedly starts and stops, it will lead to deterioration in operating efficiency and increase in power consumption, so solving this problem can be said to be a major problem required for elevators6. From such a thing.

The purpose of this system is to control the operation so that the elevator stops every other floor in response to a car call, thereby reducing the number of stops by half.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, car call signals and elevator position signals for the upper and lower floors of the car are connected in series with the destination floor pushbutton switch in the car.

(Function) When a user enters the elevator and presses the destination floor button for the destination floor, the destination floor buttons for the floors above and below are disabled and car calls are restricted. Furthermore, even if you try to get on a stopped elevator and go to the floor directly above or below, and press the destination floor button, the car call will not be registered.

(Example) The present invention will be explained based on an example shown in FIGS. 1 and 2.

This embodiment shows a case where the elevator stops at the 1st to 7th floors.

The car call circuit for each destination floor is the destination floor pushbutton switch 1.
-7 in series with the b contacts 11b to 17b of the car call registration relays 11 to 17 on the floors immediately above and directly below, and
Elevator position detection limit switches 21 to 27 on each floor and the floors immediately above and below, and relays for registering 11 to 27
17 are connected in series, and at the same time, the a contacts 11a to 17a of the car call registration relays 11 to 17 are connected in parallel with the destination floor pushbutton switches 1 to 7 to form a self-holding circuit. In addition, here, the limit switch 21 for detecting the car position
27 opens when the elevator arrives at that floor.

In addition, the a contact 11a of the car call registration relays 11 to 17
17a are connected to the car call registration circuit 30.

In the above electric circuit, let us take as an example a case where a user gets on the elevator on the first floor and goes to the fourth floor.

When the passenger presses the destination floor pushbutton switch 4 on the 4th floor, the b contacts 13b and 15b of the car call registration relays 13 and 15 on the 3rd and 5th floors are closed, and the position detection limit switches 23 to 25 are also closed. Since the circuit is closed, the 4th floor car call registration relay 14 is activated, and the a contact of the 4th floor car call registration relay 14, which is parallel to the 4th floor destination floor pushbutton switch 4, is closed. The car call on the 4th floor is self-retained. At the same time, the a contact 14a connected to the car call registration circuit 30 is also closed, and the car call is registered. Furthermore, the b contact 14b of the relay 14 for car call registration on the 4th floor opens the car call circuits on the 5th and 3rd floors directly above and below.
Car call registration on the 5th and 5th floors is prohibited.

When the elevator reaches the fourth floor, the limit switch 24 for detecting the position of the fourth floor is opened, the self-holding circuit is released, and there is no car call for the fourth floor, so the elevator stops. At this time, even if the user on the 4th floor gets into the elevator and presses the destination floor pushbutton switch 3 or 5 for the 3rd or 5th floor, the position detection limit switch 24 for the 4th floor will not activate the car call circuit for the 3rd or 5th floors. Since the circuit is open, car calls on the 3rd and 5th floors are not registered.

According to the above configuration, the prohibition of car call registration on floors above and below the registered destination floor (car call) continues until the elevator is three or more floors away from the floor where the car call was registered.

〔Effect of the invention〕

As explained above, according to the present invention, car calls are registered for every other floor, so the number of floors where the elevator stops is halved, thereby improving the operating efficiency of the elevator and saving energy.
