Description

[Detailed Description of the Invention] Industrial Application Field The present invention includes a sleeve door and an automatic opening/closing door, and the automatic opening/closing door slides open and close in normal times, and the sleeve door and the automatic opening/closing door slide open and close in normal times. The present invention relates to a method of controlling an automatic door that opens by rotating the opening so that the entire opening can be opened.

Conventional technology In a fully opening automatic door, when the automatic opening/closing door is rotated together with the sleeve door, the power to the motor that drives the automatic opening/closing door is cut off retroactively to stop the automatic opening/closing door from sliding open/close. When the automatic opening/closing door returns to its proper state, the motor is turned on and the automatic opening/closing shaft slides open and close.

Problems to be Solved by the Invention As mentioned above, the automatic opening/closing door is rotated together with the sleeve door by hand, so if it is slid open/closed at high speed immediately after returning to the normal state, it may collide with a person. It is extremely dangerous as nine people's hands may get caught in the butt.

Means and effect for solving the problem: After the automatic opening/closing door is opened once, it returns to the normal state, and the next time, the automatic opening/closing door is paused for a certain period of time, and then slides open/close in the normal operation sequence. , to prevent collisions with people or accidental pinching of hands, etc.

Embodiment The door frame 1 includes a blind 2 and left and right vertical frames 3, 3, and the opening 4 has an automatic opening/closing door 5 that slides open and close during normal times and a shaft door 6 that is fixed during normal times. Installed, automatic opening/closing door 5
is a frame assembly in which a glass 10 is mounted inside the frame assembly consisting of the upper and lower frames 7, 8 and the left and right vertical frames 9, and the shaft door 6 is attached to the upper and lower frames 11. +
2 and hanging frame! A glass 15 is mounted inside a frame assembly consisting of a frame 3 and a door frame 14, and the upper and lower sides of the hanging frame 13 are supported by hinges 16 so as to be rotatable in the out-of-plane direction between the frame 2 and the base IR+7. In addition, a latch mechanism 18 for engaging and disengaging the upper stile 11 and the blind 2 is provided across the upper stile 11 and the blind 2.

A drive unit 22 and a driven pulley 23 that fit within the motor 20 and the drive pulley 21 are disposed in the blind 2, and a belt 24 is wound around both pulleys.
A moving body 25 is connected to 4, and this moving body 25 is guided by rails 26 and rollers 27 across the entire width of the opening, and is attached to one vertical stile 9 of the automatic opening/closing door 5. The moving body 2 is rotatably connected to the other vertical frame 9 by a hinge 2B.
5 and the vertical stile 9 are connected via a latch mechanism 29 for engaging and disengaging them.

The latch mechanism +8.29 is normally in an engaged and held state, and becomes rotatable in an out-of-plane direction by operating an operating member (not shown).

A reed switch 30 and a magnet 31 are provided facing each other at a position away from the hinge 16 in the upper stile 11 of the blind 2 and the shaft portion n6, and on the side of the stile door front stile 14. When the shaft door 6 rotates together with the automatic opening/closing door 5 and becomes open, it separates from the magnet 31 and turns OFF.
Therefore, in the normal state, O is opposite to the magnet 31.
N, and constitutes an automatic opening/closing door open detector A.

FIG. 1 is a control circuit diagram, which includes a controller 43 consisting of a control circuit 41 connected to an AC power source 4o and a motor drive circuit 42, and a human body detection signal R1 from a human body detector 44 is input to the control circuit 41. Based on a predetermined operation sequence, high-speed signal H1 low-speed signal L, open signal O11
Signal C and brake signal B are input into the motor drive circuit 42, and the motor 2o rotates in high-speed forward rotation, high-speed reverse rotation, low-speed forward rotation,
The automatic opening/closing door 5 is opened and closed at high and low speeds by rotating in reverse at low speed and sliding to open and close.

A power supply circuit 45 is provided between the AC power supply 40 and the controller 43, and when the reed switch 30 is ON, that is, when the automatic opening/closing door is in the normal state, the controller 4
3 is energized, and the reed switch 30 is set to Ot″F.
In other words, when the automatic opening/closing door is rotated around the hinge and opened, the power to the controller 43 is cut off, and when the controller 43H is switched from the energized state to the cut-off state, the operation sequence is interrupted. Even if the output of each signal is prohibited and the motor 20 is stopped, the normal operation sequence will resume after a certain period of time set by the timer when switching to the fresh state and then switching to the energized state again. The automatic opening/closing door 5 is designed to slide open/close based on this.

Next, control of the automatic opening/closing door 5 will be explained based on the drawings.

When the automatic opening/closing door 5 is in the normal state, the reed switch 30 faces the magnet 31 and turns on, so the power supply circuit 45 is closed and the controller 43 is energized, so the automatic opening/closing door 5 is activated in advance by the human body detection signal R1. Opening and closing operations are performed based on a predetermined sequence of operations.

When the automatic opening/closing door 5 is opened/closed by a person and rotated together with the shaft door 6 to open the automatic opening/closing door 5, the reed switch 3o is separated from the magnet 31 and the reed switch 3o is separated from the magnet 31 and the
becomes FF, the power supply circuit 45 becomes open, and the controller 43
Since the energization to is cut off, the motor M stops prior to the operation sequence, and the automatic opening/closing door 5 immediately stops and assumes, for example, a half-open position.

Thereafter, when the automatic opening/closing door 5 is rotated to the normal state in the same manner as described above, the reed switch 30 is turned on facing the magnet 31, the power supply circuit 45 is closed, and the controller 43 is energized.

As a result, the control circuit 41 controls the set time of the timer 46,
For example, it pauses for 5 seconds, and when the timer 46 times up, it outputs each signal based on a preset operation sequence and slides the automatic opening/closing door 5.

The above operation is illustrated in a flowchart as shown in Figure @4.

In the above embodiment, the power supply to the controller 43 is cut off when the reed switch 30 is turned OFF, but the present invention is not limited to this, and when the reed switch 30 is turned ON,
Directly input OFF to the control circuit 41 and turn off the reed switch 3.
The drive of the motor 20 may be prohibited and stopped when the reed switch 30 is turned OFF at 0, and the normal opening/closing operation may be performed after a predetermined period of time has elapsed when the reed switch 30 is turned ON again.

In other words, when the automatic opening/closing door opens, the sliding movement of the automatic opening/closing door 5 is immediately stopped, and when the automatic opening/closing door 5 returns to the normal state again, the timer 46 is started, and after the timer 46 times up (a certain period of time has passed), the sliding movement of the automatic opening/closing door 5 is stopped immediately. The slide opening/closing operation may be performed in a normal operation sequence.

Effects of the Invention When the automatic opening/closing door 5 returns to the normal state from the open state, the automatic opening/closing door 5 pauses for a certain period of time and then resumes the normal opening/closing operation. It is safe because the hand of the person rotating the automatic opening/closing door 5 will not be accidentally caught, and the automatic opening/closing door will not collide with a person when it starts moving rapidly.
