Description

Description: TECHNICAL FIELD The present invention includes a sleeve door and an automatic opening / closing door, and the automatic opening / closing door slides open / closes in normal times, and the sleeve door and the automatic opening / closing door are provided in an emergency. The present invention relates to a control method for a fully open type automatic door that can be rotated to open the entire opening.

Conventional technology For fully open type automatic doors, when rotating the automatic opening / closing door together with the sleeve door, the power of the motor driving the automatic opening / closing door is shut off and the automatic opening / closing door is stopped so that it does not slide open / close. When the door opens and returns to the normal state, the motor power is turned on and the automatic door slides open and close.

Problems to be Solved by the Invention As described above, the automatic opening / closing door is rotated by the hand of the person together with the sleeve door. A collision or a pinch of a person's hand is extremely dangerous.

[Means and Actions for Solving Problems]

In normal times, the sleeve door is stopped and the automatic opening / closing door slides open / close in the normal operation sequence based on the human body detection signal, and in an emergency etc., the sleeve door together with the automatic opening / closing door is turned to the open state by the human hand. Stop the sliding movement of the automatic door when
When the human body detection signal is input when the sleeve door is closed by human hands again together with the automatic opening / closing door, the automatic opening / closing door is opened at low speed, and if the human body detection signal is not input, it is automatically opened / closed. A control method for a fully-open type automatic door in which the door is closed at a low speed, and then the slide is opened and closed in the normal operation sequence described above.

Accordingly, when the automatic opening / closing door is rotated and opened / closed together with the sleeve door, the automatic opening / closing door does not collide with a person or a person's hand is mistakenly caught.

Embodiment A door frame 1 is provided with a blind 2 and left and right vertical frames 3 and 3, and an opening 4 thereof is an automatic opening / closing door 5 which is slidably opened / closed in a normal state and a sleeve door 6 which is fixed in a normal state. Is installed and the automatic door 5
Is a frame assembly including upper and lower frames 7 and 8 and left and right vertical frames 9, and a glass 10 is mounted in the frame assembly.
The glass frame 15 is mounted in a frame assembly consisting of the frame 2, the suspension frame 13 and the door frame 14, and the upper and lower sides of the suspension frame 13 are hinges 16 which rotate in the out-of-plane direction between the blind 2 and the base 17. A latch mechanism 18 is movably supported and is provided across the upper frame 11 and the seamless frame 2 for engaging and disengaging the upper frame 11 and the seamless frame 2.

The blind 2 is provided with a drive unit 22 including a motor 20 and a drive pulley 21, and a driven pulley 23. A belt 24 is wound around both pulleys, and the belt 2
4, a moving body 25 is connected, and the moving body 25 is guided by a rail 26 and a roller 27 over the entire width of the opening, and a hinge 28 is attached to one of the vertical frames 9 of the automatic opening / closing door 5. Is rotatably connected to the other vertical frame 9 through a latch mechanism 29 for engaging and disengaging the moving body 25 and the vertical frame 9.

The latch mechanisms 18 and 29 are normally in an engaged and held state, and can be turned in the out-of-plane direction by operating an operation member (not shown).

A lead switch 30 and a magnet 31 are provided facing each other at a position apart from the hinge 16 in the upper frame 11 of the seamless door 2 and the sleeve door 6, that is, on the door end frame 14 side. When the sleeve door 6 rotates together with the automatic opening / closing door 5 and becomes open, it separates from the magnet 31 and turns off.
Is turned on, facing the magnet 31 in the normal state.
The automatic opening / closing door open detector A is configured in such a manner as described above.

FIG. 1 is a control circuit diagram, which includes a controller 43 including a control circuit 41 connected to an AC power source 40 and a motor drive circuit 42, and a human body detector 44 inputs a human body detection signal R ₁ to the control circuit 41. The high-speed signal H, the low-speed signal L, the open signal O, the close signal C, and the brake signal B are sequentially input to the motor drive circuit 42 based on a predetermined operation sequence such that the motor 20 rotates in the high-speed forward rotation, high-speed reverse rotation, The automatic opening / closing door 5 is opened and closed at high and low speeds by sliding at low speed and normal rotation at low speed and slidingly opening and closing.

A power supply circuit 45 is provided between the AC power supply 40 and the controller 43. When the reed switch 30 is ON, that is, when the automatic door is in a normal state, the controller 43 is energized and the reed switch 30 is turned OFF. At that time, that is, when the automatic opening / closing door is rotated about the hinge and is open, the power supply to the controller 43 is cut off. When the controller 43 is switched from the power supply state to the cutoff state, the operation sequence is changed. The output of each signal is prohibited to stop the motor 20 even in the middle of the operation, and the low-speed signal L and the open signal are given priority over the operation sequence by switching to the cutoff state and then to the energized state again. O or a closing signal C is output.

Next, the control of the automatic door 5 will be described with reference to the drawings.

When the automatic door 5 is in the normal state, the reed switch 30 faces the magnet 31 and is turned on, so that the power supply circuit 45 is closed and the controller 43 is energized, so that the automatic door 5 receives the human detection signal R ₁ . The opening / closing operation is performed based on a predetermined operation sequence.

When the automatic opening / closing door 5 is opened and closed by turning the automatic opening / closing door 5 together with the sleeve door 6 by the hand of the person, the reed switch 30 is separated from the magnet 31.
Since the power supply circuit 45 becomes F and the power supply to the controller 43 is cut off, the motor M is stopped in priority to the operation sequence, and the automatic opening / closing door 5 is immediately stopped and becomes, for example, a half open position.

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

As a result, the control circuit 41 outputs the low speed signal L and the open signal O in priority to the operation sequence when the human body detection signal R ₁ is input to rotate the motor 20 at a low speed to reverse the automatic opening / closing door 5 to the end. Open at low speed. When reaching the open end, the high-speed signal H and the close signal C are output to rotate the motor 20 at high speed in the forward direction to close the automatic opening / closing door 5 at the high-speed closing operation to stop the motor 20. At this time, when the human body detection signal R ₁ is input, the normal opening operation is performed based on the operation sequence.

On the other hand, when the human body detection signal R ₁ is not input to the control circuit 41, the control circuit 41 outputs the low speed signal L and the closing signal C in preference to the operation sequence, and drives the motor 20 at a low speed forward rotation to automatically open and close the door. 5 is closed at a low speed until the closing end, and the motor 20 is stopped. At this time, when the human body detection signal R ₁ is input, the above operation is performed.

The above operation is shown in a flow chart as shown in FIG.

In the above embodiment, the power supply to the controller 43 is cut off when the lead switch 30 is turned off. However, the invention is not limited to this. When the lead switch 30 is turned off, the drive of the motor 20 is prohibited and stopped. The motor 20 may be driven as described above when the lead switch 30 is turned on.

That is, when the automatic opening / closing door 5 is opened, 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 low-speed closing operation or the low-speed opening operation is performed, and then the closing operation is performed. The slide opening / closing operation may be performed in the operation sequence.

Advantageous Effects of the Invention When the automatic opening / closing door rotates and opens together with the sleeve door, the automatic opening / closing door stops, and when the opened automatic opening / closing door rotates and closes with the sleeve door, the human body detection signal causes low speed. The door opens at a low speed and closes at a low speed if no human body detection signal is input. It is safe because it is not accidentally pinched, and the automatic opening / closing door does not close unnecessarily when the human body detection signal is not input.
