Abstract

PURPOSE:To effectively prevent a door from jumping at the time of closing by using a single-phase motor as a drive source, and continuing to supply a single-phase AC to a secondary winding always at the time of closing. CONSTITUTION:When a passenger comes, a single-phase AC is supplied to the first winding M1 of a single-phase motor M by an opening door driver OL according to an opening door signal from a mat switch or the like, the motor M is rotated in a door opening direction to open a door. When a sufficient time is elapsed for the passenger, the supply of the single-phase AC to the driver OL is stopped by an inversion switch or the like, the single phase AC is supplied instead to the second winding M2 of the motor M through the driver OL, the motor M is reversed to move the door in its closing direction. The single-phase AC reduced at its voltage by a capacitor C is supplied through a closure holding circuit HL to the second winding M2 at the final stage of the closing operation, and the door is held in its closing state without jumping.

In order to prevent such a gap from occurring, a means is provided for applying a first-stage brake to the door, and after the first-stage brake is released, the first stage is decelerated and rotated to close the door. The first stage brake is applied to brake, and after this first stage brake is released, the first stage is rotated at a certain speed, and then 1! A means for applying a second stage brake to the motive force, and after the second stage brake is released, a second stage deceleration rotation is performed to close the door, and a first stage deceleration rotation or a second stage deceleration rotation is always applied. Measures are being taken to ensure that this is not the case.

There is a drawback that if resistance such as pressure is applied to the door, the door will not move in the closing direction. In the second method, the brakes are applied twice, so the first stage deceleration rotation can be made much faster, so the door will not become stiff due to wind pressure, etc. However, the door's servile drive VC is generally driven by a cable such as a V-belt. Because it uses a body, there is a drawback that a gap is created between the mullion and the door after the second stage deceleration is released. (9) As a means to eliminate this drawback in such a means, a detent is provided on the outer side of the wheel that transmits power on the rail by second-stage deceleration rotation so as to face the rail and become gradually narrower toward the terminal end. One possible method is to brake the wheels by making them come into contact with the member, and then clamp the wheels between the rail and the detent member and stop them in the next state so that there is no gap between the mullion and the door. The problem is that if the wheel is inserted too far, it will not come out and opening becomes difficult, and if it is not inserted enough, it will not be possible to sufficiently prevent the wheel from bouncing back. Furthermore, in the third means, generally FIGS.
The circuit shown in the figure is used, and the one shown in Figure 5 reduces the single-phase AC supplied to the single-phase motor M(1) to the second winding M to a desired voltage using a variable resistor VR. If the current is constantly supplied and fc is used, the 6 variable resistors v14 will heat up and be destroyed, and the large capacity variable resistor VR
Even in the case where the variable resistor ya is used, the heat generated from the variable resistor ya is large and has an adverse effect on other electronic components.

Furthermore, as shown in FIG. 7, in a configuration in which the voltage is lowered by the secondary voltage of the transformer T, there is a problem that if current is constantly supplied, the transformer T heats up and adversely affects other electronic components.
