no. 1 approach

[0061] figure 1 In order to illustrate a schematic block diagram of an outline of the automatic gate 1 of the first embodiment of the present invention. On the motor 4, a drive pulley 5 is mounted via an omitted allelery, and the frame is provided with a belt 7 between its and the driven pulley 6. The door sectors 2a, 2b are connected to the belt 7 through the belt clips 8a, 8b provided thereon, moving in the opening direction through the forward rotation of the motor 4, and the direction is moved in the direction of the direction. The drive unit 9 of the automatic door formed by the motor 4, the drive pulley 5, the driven pulley 6, and the belt 7, and the like are disposed above the door segments 2a, 2b.

[0062] Further, at the lower portion of the door sectors 2a, 2b, the upper lock units 3a, 3b composed of pin locks are mounted, so that the door sectors 2a, 2b can be locked or unlocked.

[0063] On the automatic door, the person detecting unit 15 is connected to the passagers...

no. 2 approach

[0134] Since the implementation 2 is only Figure 7 The abnormality detection shown is different from one of the programs to avoid the program, and thus only the different structures will be described, and for other configurations, since the same configuration as in the first embodiment, the description is omitted.

[0135] Figure 9 The flow diagram of the plug is avoided when the abnormality detection of the second embodiment. in Figure 7 The abnormality detection position in the open operation is located within a predetermined range from the closing completion position (step 5), transferred to Figure 9 When the abnormality detection, the finger is increated to avoid the program (in the box of the broken line). As a finger clam avoidance, the control unit 12 passes through a predetermined time, and the driving current in the opening direction of the motor 4 gradually decreases to substantially zero (step 31), then, the stop of the motor is stopped, the motor is stopped (Step 32),...

no. 3 approach

[0140] Since the implementation 3 is only Figure 7 Different from the different configurations of the exemplary embodiment, the illustrated exception detection is different from the first embodiment, and thus only the different structures will be described, and for other configurations, since the same structure as the first embodiment, the description will be omitted.

[0141] Figure 10 The flow chart of the exemption avoiding the program is avoided when the abnormality detection of the third embodiment. in Figure 7 The abnormality detection position in the open operation is located within a predetermined range from the closing completion position (step 5), transferred to Figure 10 When the abnormality detection, the finger is increated to avoid the program (in the box of the broken line). The control unit 12 determines whether or not the position of the door sector after the predetermined time standby from the abnormality is located in a predetermined range from the position of ...

Abstract

The present invention provides a safe automatic door and a control method thereof that prevent passers-by from being injured by pinching their fingers even if power is turned on in a locked state due to misoperation. The automatic door has: a driving unit, which includes a motor, and opens and closes the door leaf; a control unit, which controls the opening and closing of the door leaf, and the control unit has an opening movement obstruction detection unit, and the opening movement obstruction detection unit Detecting that the opening operation of the door leaf is hindered, when the position of the door leaf is within a predetermined range from the completion of closing, when the opening operation of the door leaf is detected to be hindered by the opening operation obstruction detection unit In the case of , the driving current in the opening direction supplied to the motor of the driving unit is gradually reduced to substantially zero over a predetermined time.

Description

Technical field [0001] The present invention relates to an abnormality in which a passive person's security automatic door and its control method can be ensured even in the open shut-off operation of the door sector due to misoperation operation of the automatic door. Background technique [0002] In the automatic door, there is a lot of automatic doors that make the upper lock or unlocking pin lock of the door to the door of the door. The manager operates the key from the outer side of the house, and the lock pin of the pin is retracted in the lower portion of the door fan, thereby performing the upper lock or unlock of the door leaf. The latched operation requires the power to cut off the automatic door in a state where the door is closed, and the unlocked operation needs to be performed before the power of the automatic door. The matter is noted in the instruction manual of the automatic door, but it is difficult to completely prevent the following mistakes, that is, the lock ...
