no. 1 approach

[0061] figure 1 It is a block diagram illustrating the outline of the automatic door 1 according to Embodiment 1 of the present invention. A driving pulley 5 is attached to the motor 4 via a speed reducer (not shown), and a belt 7 is stretched between the driving pulley 6 and the driven pulley 6 . The doors 2A, 2B are connected to the belt 7 via the belt clamps 8A, 8B provided on the upper parts thereof, move in the opening direction by forward rotation of the motor 4 , and move in the closing direction by reverse rotation. A driving unit 9 for an automatic door including a motor 4, a driving pulley 5, a driven pulley 6, a belt 7, and the like is disposed above the door leaves 2A, 2B.

[0062] In addition, locking means 3A, 3B constituted by pin locks are attached to the lower parts of the doors 2A, 2B so that the doors 2A, 2B can be locked or unlocked.

[0063] The automatic door is connected with a person detection unit 15 that detects a person passing through the doors 2A...

[0135] Since Embodiment 2 is only available in Figure 7 The shown abnormality detection part of the finger-trap avoidance program differs from the first embodiment, so only the different configuration will be described, and other configurations are the same as those in the first embodiment, so descriptions will be omitted.

[0136] Figure 9 It is a flow chart of the finger pinching avoidance program at the time of abnormality detection in Embodiment 2. exist Figure 7 In the case where the abnormality detection position during the opening operation is within a predetermined range from the closing completion position (step 5), transfer to Figure 9 The finger pinch avoidance procedure during anomaly detection (inside the dotted box). As finger pinching avoidance processing, control unit 12 makes the driving current of the opening direction of motor 4 gradually reduce to substantially zero (step 31) through predetermined time, then, wait for the stop of motor, confirm the s...

no. 3 approach

[0141] Since Embodiment 3 is only available in Figure 7 The shown abnormality detection differs from Embodiment 1 in that a part of the finger-trap avoidance program is different, so only the different configuration will be described, and other configurations are the same as those in Embodiment 1, so descriptions will be omitted.

Abstract

The present invention provides a safe automatic door and a control method of the same; even if the power is turned on in a locked state due to an erroneous operation, the automatic door does not causea person to be injured by the fingers being caught. The automatic door has the following parts: a drive unit that includes a motor and opens and closes a door leaf; a control unit that controls the opening and closing of the door leaf; the control unit has an opening motion obstruction detection unit; and opening motion obstruction detection unit detects that the opening movement of the door leafis obstructed or not; when the door leaf position is within a predetermined range from the completion of closing, and the opening motion obstruction detection unit detects the opening operation of the door leaf is obstructed, the drive current in the opening direction to the motor of the drive unit can be gradually reduced to substantially zero after a predetermined period of time,.

Description

technical field [0001] The present invention relates to an automatic door capable of ensuring the safety of passers-by even when an abnormality occurs in the opening and closing operation of a door leaf due to an erroneous operation of the automatic door or the like, and a control method thereof. Background technique [0002] Among the automatic doors, there are many automatic doors in which a pin lock for allowing an administrator to lock or unlock the door leaf is attached to the lower part of the door leaf. The administrator operates the thumbpin from the inside of the house and the key from the outside of the house, so that the pin of the stud lock advances and retreats in the lower part of the door, thereby locking or unlocking the door. The operation of locking needs to be performed after the power supply of the automatic door is cut off when the door leaves are closed, and the operation of unlocking needs to be performed before the power supply of the automatic door i...
