CONSTITUTION:When an opening button OP is pressed during the door being closed, a power supply P-contact 104b2-contact 100a1-button OP-relay-100-safety shoe switch SS-the opening/closing command relay 100 of the circuit of a power supply N are de-energized so as to close a contact 100b, and a door opening command relay 102 is thereby energized to perform door opening action. When a closing button CL is pressed at the intermediate time of door opening action, the opening/closing command relay 100 is energized so as to close a contact 100a2. A door opening detecting switch CS is also closed, and a door closing command relay 102 is energized with the circuit structure of power supply P-contact 100a2-switch CS-relay 101-switch CLS power supply N. A contact 101b2 is thereby opened to de-energize the door opening command relay 102, and the door opening action is interrupted. Simultaneously, door closing action is performed by the energization of the door closing command relay 101.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator door opening/closing control device.

[Conventional technology]

Conventionally, the elevator door opening/closing control device was developed in U.S. Pat.
As described in Japanese Patent No. 23376, the door cannot be closed until the opening is completed.

[Problem to be solved by the invention]

When there are few passengers getting on and off, passengers often get on and off the train before the door is fully opened. Further, there are cases where a car call is registered by mistake, or a hall call is registered but the user ends up getting on another elevator, and so on, even though the call is registered, there are no passengers getting on or off the elevator. Even in such cases,
According to the conventional door opening/closing control device, since the door does not close until it is completely opened, there is a problem that the door is opened for a longer time than necessary.

An object of the present invention is to provide an elevator door opening/closing control device that can shorten the door opening time.

[Means to solve the problem]

The above purpose is to provide an open door detection switch that operates when the door opens to a predetermined halfway position while the door is open, and also to provide a control circuit with an open door detection switch that operates when the door close button is pressed while the open door detection switch is operating. This is accomplished by providing a circuit that de-energizes the command relay and energizes the door-closing command relay.

[Effect]

If passengers have boarded or alighted before the door fully opens, or if there is a call registration but there are no passengers getting on or off, by pressing the close button, the door that is in the middle of opening will be moved to a predetermined halfway position where the door open detection switch will operate. Flip it over and begin to close it. Thereby, the time required to open and close the door is not extended more than necessary, and the opening time of the door can be shortened.
