Abstract

(57) [Abstract] [Purpose] To provide a door opening time limit control device for an elevator that enables setting of the door opening time limit according to the number of passengers. [Structure] The load displacement detection device PW in the car detects the displacement of the load in the car, the comparator CM performs a comparison calculation, and the door opening time setting device DW sets the door opening time by the output thereof. [Effect] Since the door closing operation is performed after the passengers get on and off the vehicle, the door closing operation does not occur in the course of getting in, and the safety and the driving efficiency can be improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator door opening time limit control device, and more particularly to an elevator door opening time limit control device suitable for improving service on a floor with many users.

[0002]

[Prior art]

 As a method of detecting the number of waiting customers in the hall and efficiently moving the elevator according to the number of waiting customers, for example, as disclosed in Japanese Utility Model Publication No. 56-47859, the number of waiting customers in the hall is detected. When the number of waiting passengers exceeded a predetermined value, multiple elevators were selected and serviced for the hall call.

[0003]

[Problems to be solved by the device]

 Although the above-mentioned conventional technology is effective in servicing passengers in the hall, it does not consider driving for all passengers getting on and off, regardless of whether many passengers get off or not. There was a problem of doing the same driving.

An object of the present invention is to remedy the above-mentioned drawbacks and to provide an elevator door opening time limit control device capable of distinguishing operations according to a floor having a large number of customers and a floor having a small number of customers. .

[0005]

[Means for Solving the Problems]

 The above purpose is to provide a service in accordance with the output from the detection means for detecting the fluctuation of the load in the car and outputting the output in the door opening time limit control device for the elevator that serves a plurality of floors. This can be achieved by providing variable means for changing the door opening time on the floor.

[0006]

[Operation] The detection means for detecting the displacement of the load in the car emits an output according to the situation of the passengers getting on and off the car, and changes the door opening time period based on this output. In other words, when there are many customers, the door opening time limit should be long, and when there are few customers, it should be shortened.

【Example】

 An embodiment of the present invention will be described below with reference to the block diagram of FIG. 1 and the circuit diagram of FIG.

The entire flow will be described with reference to FIG. In FIG. 1, PW is an in-car load displacement detection device that detects the displacement of the load in the car, and outputs an output according to the displacement of the load in the car. The GW is a predetermined load displacement setting device, which constantly outputs an output serving as a displacement reference. The CM is a comparator, which compares the inputs of the in-car load / displacement detection device PW and the predetermined load / displacement setting device GW and outputs the output to the place where the passenger is getting on and off. DW is a door opening time limit setting device, which sets the door opening time limit by input from the comparator CM.

Next, the operation will be described. As an example, the case where there are many users and the displacement of the load in the car continues for a long time, that is, the case where the door opening time period is lengthened, will be described. Since there are many passengers getting on and off, the output of the in-car load displacement detection device PW is large and lasts for a long time. The predetermined load displacement setting device GW outputs a reference output. The comparator CM inputs the signal of the in-car load displacement detection device PW and the signal of the predetermined load-displacement setting device GW, and since the input of the in-car load displacement detection device is large, there are many passengers getting on and off the elevator. Judges and outputs no output signal. Next, when the elevator getting on and off is completed, the output of the in-car load displacement detection device PW becomes small. The comparator CM inputs signals from the in-car load / displacement detection device PW and the predetermined load / displacement setting device GW, and judges that the elevator has finished getting on / off because the input of the in-car load / displacement detection device is small, and outputs an output signal. . The output signal is input to the door opening time setting device DW and the door opening time is cut off.

In FIG. 2, P and N are DC power supply terminals, S1 is an output signal from a comparator, DW1 is a timer, DW1a is a normally open contact of DW1, and DT is a door close command contactor. A closing start signal is given to the door control circuit.

The conditions will be described as the same as those described above. The output signal S1 is open because the displacement of the load in the car continues for a long time because there are many users. When the use of the elevator is completed, that is, when the load in the car is not displaced, the output signal S1 is closed. The circuit of P-S1-DW1-N is formed by closing S1, and the timer DW1 is of a timed operation type and is energized after a predetermined time elapses. DW1 a is closed by the activation of the timer DW1. When the DW1a is closed, a circuit of P-DW1a-DT-N is formed and the door close command contactor DT is energized. The door control circuit is actuated by the urging of the door close command contactor DT to close the elevator door.

As described above, according to the present embodiment, the door opening time period can be set by the displacement of the load in the car, so that it is possible to safely get on and off when there are many passengers and to operate efficiently.

[0013]

[Effect of device]

 As described above, according to the present invention, the door opening time limit can be set according to the number of passengers, so that safety is improved and operation efficiency is improved.
