At the door closing position of the horizontal frame 14, a closing limit switch 10 for detecting the closing of the door 1 is provided, and
An open limit switch 11 for detecting that the door 1 is fully opened is provided at the door fully open position of the horizontal frame 14.

In the figure, A is a controller, 5 is a main power switch, and 6 is a sub power switch.

A mat switch 9 is provided at the fully closed position of the door 1 and serves as a start switch for opening the door 1.

The controller A of the present embodiment will be described next with reference to FIG. 2. The controller A includes a motor control unit 4, a reversal number counting unit 2, a door opening storage unit 3, a pulse counting unit 20 and a pulse storage unit 21. Consists of.

The motor control unit 4 controls the rotation direction, rotation angle and rotation speed of the motor 7, and controls the opening / closing movement of the door 1 via a transmission mechanism such as a belt 8.

The motor 7 is provided with a pulse generator for generating a current of a pulse number proportional to the rotation angle of the motor 7, and the pulse generator is connected to the pulse counting section 20.

The pulse counting unit 20 counts the number of pulses of the pulse generator to input the number of pulses corresponding to the initial half-open position of the door (b in FIG. 3), that is, the half-open setting position, to the pulse storage unit 21. In addition, while the motor 7 is being driven, the number of pulses corresponding to the rotation angle is input to the motor controller 4 at every instant.

The pulse storage unit 21 is connected to the main power switch 5, the pulse counting unit 20, and the motor control unit 4, and stores the number of pulses when the main power switch 5 is turned on. It corresponds to the half-open position of the door. Then, when the motor 7 is being driven, the number of pulses corresponding to the half-open position of the door is input to the motor control unit 4 and stopped at the half-open position of the door.

The reversal number counting unit 2 counts the number of times the mat switch 9 is activated when the door 1 is in the middle of the closing stroke and is reversed in the opening stroke, and inputs the counted number to the motor control unit 4 at every moment.

The door opening degree storage unit 3 sets and stores the door opening degree corresponding to the predetermined number of times of reversal. For example, the predetermined number of times of reversal is set to N, and when the number of times of reversal reaches N, the first half-opening of the door is performed. The degree (initial half open, b in FIG. 3) plus L (for example, 20 cm) is set and stored so as to be the next door opening (halfway open halfway, c in FIG. 3).

The motor control unit 4 increases the door opening when the number of reversals reaches a predetermined number of reversals based on the inputs of the reversal counting unit 2 and the door opening storage unit 3 and sets the door to the door opening. It is to open it.

The motor control unit 4 includes a mat switch 9, a closed limit switch 10 and an open limit switch 11.
Are connected respectively.

If the initial half-open position (b in FIG. 3) is too narrow, it cannot be used unless it is opened, for example, about 10 cm. Therefore, the pulse storage unit 21 is preset with the number of pulses corresponding to 40 cm opening. Therefore, cancel all settings below 40 cm and set it to 40 cm.

FIGS. 4 to 6 are flow charts showing an example of the control according to the present embodiment. The opening / closing operation of the door based on this control will be specifically described with reference to FIGS. 3 (a) to 3 (d). (a) shows fully closed, (b) shows initial half open, (c) shows halfway open, and (d) shows full open.

The case of the fully open mode of manual fixing will be described (FIG. 7). In the standard one stroke, the mat switch 9 is turned on, the door 1 is moved from the fully closed state to the fully opened state, is fully opened for a certain period of time, and then is closed to be fully closed. When the mat switch 9 is turned on during the closing stroke, the mating switch 9 is reversed to the opening stroke to be fully opened, and after being fully opened again for a certain period of time, it is closed to be fully closed.

When the fully opened door is closed by 5 cm or more by an external force, it is opened again to be fully opened.

The case of the half-open mode of manual fixing will be described (FIG. 8). In one standard stroke, the mat switch 9 is turned on, the door 1 is opened from fully closed to half open, and after half open for a certain period of time, it is closed to full close. When the mat switch 9 is turned on during the closing stroke, the mating switch 9 is reversed to the opening stroke to be half-opened, and after half-opening for a certain period of time again, it is closed and fully closed.

When the start signal from the mat switch 9 is continuously input for 5 seconds or more after the half-opening is continued for a certain period of time in the half-opening stroke, the mating switch 9 is opened to shift to full-opening. If the door 1 is further opened by an external force of 5 cm or more during the half-opening stroke, the door 1 is opened to be fully opened. If the door 1 is further closed by an external force of 5 cm or more during the half-opening stroke, it opens and returns to half-opening.

The case of the automatic half-open variable mode will be described (FIG. 9), but the predetermined number of reversals N is 3 and the door opening increase (L) is 20 cm. In a standard one stroke, the mat switch 9 is turned on, the door 1 is opened from the fully closed state to the initial half open state (b in FIG. 3), and the door is closed for a certain period of time and then closed to be fully closed. When the mat switch 9 is turned on during the closing stroke, the mating switch 9 is reversed to the opening stroke to be half-opened, and after half-opening for a certain period of time again, it is closed and fully closed.

When the number of reversals reaches three times in succession, the initial half-opening degree (b in FIG. 3) plus 20 cm is set as the half-way opening degree (c in FIG. 3), and the half-opening degree is half-opened. After half-opening for a certain period of time, it closes and becomes fully closed.

In this embodiment, the door opening degree increase (L)
The width is 20 cm, but the present invention is not limited to this, and the width may be any width according to the place of use and the amount of traffic. Further, although the automatic door of this embodiment is a single door, the present invention can also be applied to a double door automatic door.
