As one method to reduce the operating time between floors, a so-called running close method has been proposed, in which when the elevator starts, the brake is released and a speed command is given to start the car before the door is completely closed. ing.

On the other hand, a predetermined condition is met, for example, when the door is forcibly closed when the door opening time exceeds a predetermined time, the number of times the door is reversed exceeds a predetermined value, or when a call for a disabled person is detected. For safety reasons, the door closing speed may be set to a slower speed than normal. Until now, if the above-mentioned running close was to be carried out, there was a problem in that the speed of the car would increase before the door was completely closed, that is, with the door open, creating a very dangerous situation.

The present invention was developed to solve the above problems, and its feature is that when the elevator is started, the brake is normally released before the doors are closed, and a speed command is given to the car. When a predetermined condition is met and the door closing speed is set slower than usual, the speed command is given after the door is closed, that is, the timing for giving the speed command to the car depends on whether the predetermined condition is met. The point is that we changed it.

Meanwhile, a door close command is output from a circuit not shown.
Contacts 26a and 26b close and the door begins its closing operation. Initially, all of the cam switches C1 to C3 are open, and all of the resistors 27 and 29 are inserted. Further, the resistor 28 is short-circuited because the contact 25c is closed. When the door begins to close and the cam switch C1 closes, a portion of the resistor 27 is short-circuited and the door motor DM accelerates. When the door reaches the deceleration area, the cam switch C1 opens and the door motor DM starts to decelerate, and then the cam switches C2 and C3 close in sequence, causing the door motor to start decelerating.
DM increases deceleration and completes door closing.
When the door is closed to a predetermined position during the door closing, the contact 17 is closed, the relay 18 is energized, and the contact 18a is closed. Further, during normal operation, the safety circuit relay 14 is energized and its contact 14a is closed. Therefore, when the door closes halfway, P-

The electromagnetic brake release contactor 15 and the speed command relay 16 are energized by the N circuit, and the contacts 15a and 1
By closing 5b, the exciting coil 10 is excited, the electromagnetic brake is released, and a speed command is given, so that the car starts running while the door is closed.

When the car runs and reaches the level of the desired stop floor, the contact 23 is opened and the operation relay 22 is deenergized, and the contactor 1 is opened by opening the normally open contact 22a.
5 is also deenergized, the electromagnetic brake is applied, and the car stops.

Next, a case will be described in which the door closing speed is set slower than usual due to the establishment of a predetermined condition.

When the door opening time exceeds a predetermined value, the door opening time detection circuit 24 is closed and the forced door closing command relay 25 is energized. This energizes the door closing relay, closing its normally open contacts 26a and 26b, and the door begins to close. The closing operation is the same as described above, but the contact 25c
The opening of the door inserts the resistor 28 so that the door closes at a slower rate than normal. Since the contact 25a is opened and the contact 25b is closed, even if the door is closed to a predetermined position and the contact 18a is closed, the contactor 15 is not energized and the electromagnetic brake is not released. When the door completes its closing operation, the contact 19 is closed, the door closed detection relay 20 is energized, and its contact 20a is closed. As a result, P-14a-25b-20a-
The electromagnetic brake release contactor 15 and the speed command relay 16 are energized by the 22a-15, 16-N circuits, the electromagnetic brake is released, and at the same time a speed command is given and the car starts running. In other words, in this case, the speed command is given after the door has been closed,
The car will start running with the door completely closed.

According to the present invention, in normal cases, a speed command is given to the car before the door is closed to perform a so-called running close, and when a predetermined condition is met and the door closing speed is set slower than usual, the door is closed. Since a speed command is given after completion, it is possible to reduce the driving time between floors, and at the same time
This prevents the dangerous situation of the car speeding up before the door is fully closed, and is highly effective in improving operational efficiency and safety.
