Abstract

PROBLEM TO BE SOLVED: To surely prevent a passenger from being caught in a door by controlling a door so that after the load in a car is detected by a weighing device, the door is closed to travel the car to a destination floor, and after landing, the door is opened, and in the case where the load in the car is not detected by the weighing device, the door is closed. SOLUTION: When a passenger uses an elevator for going to the second floor from the first floor, first the passenger presses a call button for the elevator hall of the first floor (S1). It is judged whether an elevator car is on standby at the first floor or not (S2), and if not, the car is traveled to the first floor (S3) to be landed (S4). Then, a door is opened (S5), and after the load in the car is detected by a weighing device (S7), that is, after boarding of passengers is confirmed (S8), the car is traveled to the second floor (S9), and landed (S10), and the door is opened (S11). After that, in the case where the load is detected and no load is detected, the door is closed (S13). After that, the car is on standby at the second floor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator door control device.

[0002]

2. Description of the Related Art As a conventional door control method for an elevator, a door is opened on a landing floor on which a car is pressed in response to pressing of a landing push button provided on each floor landing, and the door is opened for a predetermined time ( After about 5 seconds, close the door.

[0003] Then, the vehicle is controlled to travel to the destination floor registered by the passenger, open the door after landing, and close the door after a lapse of a predetermined time (about 3 seconds).

[0004]

However, in the above-described conventional door control method, the door is automatically closed after a predetermined time after being opened, so that in some cases, there is an inconvenience that a passenger is pinched by the door. Was.

That is, in the case of a passenger who takes a long time to get on and off between the car and the hall, such as an elderly person or a handicapped person, there is a problem that the passenger is caught by the door.

[0006] The present invention has been made in view of such inconvenience, and an object of the present invention is to prevent passengers from being reliably caught in the vehicle regardless of the time of getting on and off between the passenger's car and the landing. The present invention provides an elevator door control device capable of getting on and off a vehicle.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an elevator having a hall call button provided on each floor hall, a car and a weighing device provided in the car. In the door control device, the car opens the door after landing on the floor of the hall where the hall call button is pressed, closes the door after detecting the load in the car by the weighing device, and moves the car to the destination floor. It is characterized in that the door is closed after running, and after landing, and when the load in the car is not detected by the weighing device, the door is closed.

According to the present invention, as described above, when a passenger gets into a car, it is confirmed that the passenger has got into the car, and when the passenger gets off the car, that the passenger has got off is checked by the presence or absence of load detection in the car. Since the elevator door control device is configured to be controlled to close, the passenger can safely get on and off between the landings without being caught by the door.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, a method of detecting a load in a car which is a door control condition by the door control device of the present invention will be described with reference to FIG.

FIG. 2 is a sectional view of a car in which a general weighing device for detecting a load in a car is installed.

In the drawing, a car comprises a crosshead 2a to which a main rope 1 is connected, a sling 2b having an upper end connected to both ends of the crosshead 2a, and a base connecting a lower end of the sling 2b. 2c, and a car room 3 including a floor plate 3a supported inside the frame body 2, a side plate 3b, and a ceiling 3c.

The floor panel 3a includes a floor member 31a and a tile 32a laid on the upper surface of the floor member 31a.

The weighing device 34 includes a micro switch 4a attached to the base 2c and the micro switch 4a.
A pair of anti-vibration rubbers 5 mounted on the upper surface of a pair of, and a connecting plate 6 having both ends supported on the upper surfaces of the pair of anti-vibration rubbers 5
And a pressing member 4b attached to the connecting plate 6 so as to face the micro switch 4a, and a C-shaped member 7 disposed between the connecting plate 6 and the floor plate 3a. I have.

The operation method is as follows.
When a load is applied to the passenger from the luggage or the like, the load is applied to the C-shaped material 7 and to the vibration isolating rubber 5 via the connecting plate 6, and the vibration isolating rubber 5 is connected to the base 2c. Compresses and flexes between. Then, the pressing body 4b is displaced downward due to the bending of the vibration isolating rubber 5, and operates by pressing the microswitch 4a.
The distance between the pressing body 4b and the microswitch 4a is set to a car loading load, for example, 10 to 20 times the rated load.
By setting the pressing body 4b to press the microswitch 4a at the time of%, even if a small number of people get into the car, it can be detected.

Next, a door control method by the door control device of the present invention utilizing the above-described detection of the weighing device will be described with reference to FIG. 1 taking a small elevator ascending and descending on the second floor as an example.

FIG. 1 is a flowchart showing a door control method of the door control device of the present invention.

When the passenger uses the elevator from the first floor to the second floor, first, when the passenger presses the hall call button on the first floor (step S1), it is determined whether the first floor is waiting (step S1).
2) If it is not the first floor, drive the car to the first floor (step S3) and land on the floor (step S4). Then, the door is opened (step S5), and if the load in the car is detected by the weighing device (step S6), that is, if it is confirmed that the passenger has entered, the door is closed (step S7).

As described above, according to the present embodiment, it is possible to detect that a passenger has got into a car by the weighing device and prevent the passenger from being caught by the door. When the door closing is confirmed (step S8), the vehicle is driven to the second floor (step S9), and after landing (step S10), the door is opened (step S11). Closes the door (step S13), and then
The car waits on the second floor (step S14).

As described above, according to this embodiment, the door is closed after confirming that the passenger has got out of the car, that is, that there is no load detected by the weighing device. Can be prevented from being pinched by the door.

Further, according to the present embodiment, load detection is performed to prevent the door from continuing to open after landing on the floor where the hall call occurs and not being able to respond to a new hall call on another floor (step S).
6) After a lapse of 30 seconds from the absence (step S15), another floor call is performed.
6) The door is closed (step S5), and the call is accepted (step S17).

[0022]

According to the present invention, as described above, the door control device is configured to control the opening and closing of the door in consideration of the presence or absence of the load in the car. Regardless, it is possible to reliably prevent passengers from being caught in the door and to be able to get on and off safely.
