JPH05116875A - Elevator door controller - Google Patents

Abstract

PURPOSE:To provide an elevator door controller capable of ensuring safety in getting in and out of the elevator while leaving no passengers in the cage in getting in and out thereof by providing a means for continuously opening the door when the movement of the passengers in the cage is detected by a passenger movement detector. CONSTITUTION:When a cage 1 is full of passengers, a binary signal meaning that all switches 3a-3i stored from a binary signal clock generator 5 by a first clock pulse are opened is outputted to a terminal 7b of a comparator 7. When a passenger standing on a floor 29 to get out of the cage on the third story moves, the switch 3i is opened so that an adder 4 outputs a binary signal meaning that the switches 3a-3i are closed to a memory circuit 6 and the terminal 7a when a second clock pulse is inputted to 4j. The comparator 7 compares the binary signals of the input terminals 7a, 7b with each other to detect a difference between the input signals and output the signal to a base 8B of a transistor 8. The transistor 8 is turned ON to energize a relay 9 for continuously opening a door.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door control device for an elevator, and more particularly to a rational door control device for an elevator that controls the opening and closing of the door in response to getting on and off the elevator.

[0002]

2. Description of the Related Art Conventionally, elevator door control devices are
It is a device that automatically opens the door after arriving at the destination floor and automatically closes the door when the timer set to an arbitrary time after the full opening starts counting is set.
In the device described in Japanese Patent No. 31336, the operation efficiency of the elevator is improved by detecting the completion of getting on / off of passengers in the elevator due to the change in the load of the elevator, and immediately closing the door of the elevator to drive it to the next stop floor. There was an elevator door control that was meant to improve.

[0003]

In the above-mentioned prior art, since the door closing time is controlled by the fluctuation of the load, for example, when the elevator car is full, passengers who want to get off at the middle floor get on the rear side. However, there was a problem that it took time to get off, but it was considered that there was no change in the load, and the door closed early so that it could not go down.

Also, for users with luggage, passengers with children, etc., it is considered that there is no fluctuation in the load inside the car, and the passengers are closed during the boarding, or they hit the body. was there.

An object of the present invention is to provide a door control device for an elevator that allows passengers to get on and off safely and smoothly when getting on and off.

[0006]

In order to achieve the above object, the present invention relates to an elevator door control device which gives a door closing command after a predetermined time has elapsed since the elevator stopped and the door opened. Multiple load detectors are installed on the floor and the outputs of these load detectors are added together with the change in the added value of this adder for a certain period of time to move passengers in the car. And a door opening continuation means for continuing the door open state when the passenger movement detector detects the movement of the passenger.

[0007]

In the elevator door control device of the present invention,
The multiple load detectors on the floor of the car detect the movement of passengers in the car and keep the door open to prevent the passengers from getting on and off when leaving the vehicle and leaving the vehicle unattended. Can be provided to passengers.

Next, the operation will be described.

Now, when the car 1 is climbing from the first floor to the uppermost floor in a state of being full, it stops at the third floor on the way and a passenger standing on the floor 29 apart from the car door 1a is about to get off. When the car door 1a is fully opened, P-1OP-10-N
Circuit is formed and the activation relay 13 is energized, and the normally open contact 1
3a1 and 13a2 are closed.

Since the car 1 is full, the switches 3a to 3i
Are all closed, the input terminals 4a to 4i of the adder 4 all receive signals, and the first clock pulse from the binary signal clock generator 5 indicating that the switches 3a to 3i are all closed. When input to the terminal 4j, it is output to the memory circuit 6 and the terminal 7a of the comparator 7. Next, when the passenger standing on the floor 29 trying to get off on the third floor moves, the switch 3i opens, so that when the second clock pulse is input to 4j, the adder 4 closes the switches 3a to 3h. A binary signal indicating that the data is being generated is output to the memory circuit 6 and the terminal 7a, and the second clock pulse is input to the terminal 6a of the memory circuit 6, and the switches 3a to

Here, the comparator 7 compares the binary signals of the input terminals 7a and 7b, detects that there is the switch 3i opened by the passenger moving and the input signals are different, and outputs a signal to the base 8B of the transistor 8. , Transistor 8 is turned on and Vi-13a2-9-8C-8-8E-G
The electric current flows and the door open continuation relay 9 is energized. In this way, the door open continuation relay 9 continues to be energized until the passenger gets off the car 1, so that the circuit P-9a-14-N is formed and the door open command relay 14 continues to be energized in the same manner. The car door 1a is never closed while passengers are getting off. When a predetermined time has passed since the passenger got off, the car door 1a is closed by a door close command circuit (not shown). When the car door 1a is fully closed, the circuit P-1CL-11-N activates the door full-close detection relay 11, and P-11a-r-13-
Since the N circuit is formed, the starting relay 13 is deenergized.

In addition, the activation relay 13 has a function of P-10b-11 even if the open button 1c is operated while the car door 1a is closing the door.
b-1ca1-12-N and P-12a-S-13-N
Is activated by the circuit.

In this embodiment, the door opening is continued when the passengers get off when the passengers are full. However, since the same is true when the passengers get on, the description thereof will be omitted.

[0019]

According to the present invention, even if the inside of the car is full, the doors are kept open during the process of getting on and off, so that the passenger does not get left on the car, there is no leftover, and there is no body or luggage. It is possible to provide smooth entry and exit and safety without hitting the door.
