Regarding door devices.

Door devices that are driven by electric power are already known. Further, there are known bolt devices that lock the door so that it cannot move in the closed state, as well as tightening devices that tighten the door against the wall in the closed state in order to bring the door into close contact with the wall.

As the door device becomes larger, the tightening device and bolt device described above also become larger, and it is troublesome to operate them manually, and in some cases it is impossible to operate them manually. It is being considered that even the locking device could be driven by electric power.

However, if the door device itself, the tightening device, and the locking device are also driven by electric power, various problems will occur if each driving part can be operated independently and freely. For example, if the locking device or locking device can be operated freely when the door is retracted from the opening surface of the wall and is in the open state, the tightening device or the locking device can be adjusted to The door may be moved in the closing direction while the door is in the restrained state, and if this happens, the tightening device or the locking device will collide with the wall, and the tightening device or the locking device will be damaged. In addition, if you try to operate the door drive motor in the opening direction while the tightening device or bolt device is tightening and restraining the door against the wall, the door drive motor will be overloaded and the drive motor will burn out.

Cox is a relay circuit as shown in Figure 33.
Co is a contact point at the circuit Co, which is closed by applying a DC voltage Vcc to the circuit Co via the buffer _b1 .

Now, if you rotate the key switch KS to the second stage, contacts KS ₁ and KS ₂ will close and the voltage will drop.
Vcc is generated, which activates the relay circuit Co and closes the contact Cox. Therefore, even if the operation of the key switch KS is stopped and the key switch KS returns to stage 1, and the contact KS ₂ is turned off, the voltage Vcc
is maintained.

FIG. 34 shows a control circuit in which SW ₁ to SW ₆ ,
LS ₁ to LS ₆ , S ₁ , S ₂ , STOP, and PL ₂ to PL ₅ correspond to the above-mentioned switches and indicator lights, respectively.
In Fig. 38, _A1 to _A6 are input circuits, the specific circuit configuration of which is as shown in Fig. 35.
When the voltage Vcc is input, a high level (hereinafter abbreviated as "H") signal is output. _B1 to _B9 are also input circuits, and their specific circuit configuration is as shown in Figure 36, and when the input terminals are grounded, a low level (hereinafter abbreviated as "L") signal is output. It's becoming like that. Co to _C6 are a type of relay circuit, and their specific circuit configuration is as shown in Figure 37. When an "H" signal is input, the relay coils are energized, and each relay is activated. contact
Cox to C ₆ x can be turned on or off. a ₁ to a ₄ are AND circuits, O ₁ to O ₁₄ are OR circuits, FF ₁ to FF ₆ flip-flop circuits,
I ₁ to I ₅ are inverters, and b ₁ to b ₇ are buffers. The contacts C ₁ x to C ₆ x of the relay circuits C ₁ to C ₆ are inserted into the power supply circuit to the motors M ₁ , M ₂ , and M ₃ as shown in FIGS. 38, 39, and 40, respectively. ,
When circuit C ₁ operates, contact C ₁ x turns on and off, forming a normal rotation circuit for motor M _1. When circuit C ₂ operates, contact C ₂ A reversing circuit of _M1 is configured. Similarly, when circuit C ₃ operates, a forward rotation circuit for motor M ₂ is formed, and when circuit C ₄ operates, a reverse rotation circuit for motor M ₂ is formed.
Furthermore, the normal rotation circuit of motor _M3 is activated by circuit _C5 .
The operation of circuit C ₆ forms a reverse circuit for motor M ₃ .

The control circuit is configured to perform the following operations.

When closing the door from an open state,
First, operate switch SW ₁ . As a result, Vcc is applied to input circuit _A2 , and its output becomes "H".
The output of FF ₂ is applied to the preset terminal of FF ₂ and converted to "H", and is applied to the circuit C ₁ via b ₂ .
As a result, a normal rotation circuit for motor _M1 shown in FIG. 38 is formed. The motor _M1 corresponds to the above-mentioned driving motor 32, and the normal rotation of the motor _M1 causes the door to move in the closing direction. When the door is completely closed, the limit switch LS ₁ is turned off, and the input of the input circuit B ₅ , whose input terminal was previously grounded, is disconnected from the ground, and the output of the circuit B ₅ becomes "H". This “H” signal passes through O ₇ , O ₄ , O ₅ to FF ₂
is input as a clear signal to FF 2, the output of FF ₂ changes to "L", the operation of circuit C ₁ stops, and the 38th
The power supply to motor _M1 in the figure stops, and the door stops moving. In addition, the "H" signal of circuit B ₅ is converted to "L" by inverter I ₃ , thereby creating a potential difference in indicator light PL ₃ , lighting indicator light PL ₃ , and closing the door completely. Show that.

Next, operate SW ₃ . As a result, the output of _A3 becomes "H" and is added to _a1 . The other input terminal of a ₁ has a circuit based on the door being completely closed.
Since the "H" signal from _B5 and the "H" signal from circuit _B9 , which is generated when limit switch _LS6 detects that the bolt is completely retracted, _are added, The output becomes "H", which is
This becomes a preset signal for FF ₃ , and the output of FF ₃ becomes “H”.
Convert to This signal is applied to relay circuit _C4 via buffer _b5 , and the operation of relay circuit _C4 forms a normal rotation circuit for motor _M2 in FIG. 39.
Since the motor _M2 corresponds to the drive motor 50 of the aforementioned tightening device, the tightening device operates in the direction of tightening the door against the wall. When the door is fully tightened,
Limit switch LS ₃ operates, the output of circuit B ₆ becomes "H", this is applied to the clear terminal of FF ₃ via O ₈ , the output of FF ₃ changes to "L", and the circuit
C ₄ stops and motor M ₂ stops. Also, at this time, the "H" output of circuit B ₆ is converted to "L" by inverter I ₄ , so that the indicator lamp PL ₄ receives Vcc.
is applied and indicator light PL ₄ lights up to indicate that the tightening device is fully activated.

Next, operate switch SW ₅ . As a result, the input circuit _A5 becomes "H" and is input to _a3 . Since the "H" signal from the input circuit _B6 is applied to the other input of _a3 , _a3 becomes "H" and is applied to _FF5 as a preset signal. This results in
The output of FF ₅ becomes "H", actuating relay circuit C ₆ and forming a normal rotation circuit for motor M ₃ in FIG. 40. The motor _M3 corresponds to the aforementioned bolt drive motor 59, and causes the bolt to protrude and lock the door so that it cannot be opened. When the bolt is fully protruded, the limit switch LS ₅ that detects this is activated, and the output of circuit B ₈ becomes "H", which becomes the clear signal for FF ₆ .
The output of FF ₆ is changed to "L", relay circuit C ₅ stops, and motor M ₃ stops. Also, at this time, the voltage Vcc is applied to the indicator light PL ₅ , and the indicator light PL ₅ lights up to indicate that the bolt is fully operated.

The above was a case where the door was closed, the tightening device was activated, and the locking device was activated in that order.
By operating SW ₆ , SW ₄ , and SW ₂ in this order, the door can be opened.

First, when switch SW ₆ is operated, circuit A ₆ becomes "H" and is added to a ₄ . Since the ``H'' output signal of circuit B <sub>6</sub> is added to the other input of a <sub>4</sub> , a <sub>4</sub> becomes ``H'', which becomes the preset signal of FF ₆ , and FF ₆ becomes ``H'', which activates the relay. circuit C ₅
operates to form a reversal circuit for motor _M3 shown in FIG. This causes the bolt to retract into the door, and when it is completely retracted, limit switch LS ₆ is activated and the circuit is closed.
_B9 becomes “H” and this “H” signal is passed through _O14 .
Added to FF ₆ as a clear signal, FF ₆ becomes “L”
, circuit C ₅ stops, and motor M ₃ also stops. Additionally, the indicator light PL ₅ goes out due to the return of the limit switch LS ₅ .

Next, when switch SW ₄ is pressed, circuit A ₄ becomes "H" and this is added to a ₂ . The other two input terminals of a ₂ are the “H” output signal of circuit B ₅ and the circuit
Since the "H" output signal of _B9 is added to each, the output of _a2 becomes "H", which becomes the preset signal _of FF ₄ , which becomes "H" and activates relay circuit _C3 . . The actuation of circuit C ₃ forms the reverse circuit of motor M ₂ shown in FIG. 39, and the tightening device returns to release the tightening of the door wall by the tightening device. When the tightening device is fully restored, limit switch LS ₄ is actuated, and from circuit B ₇
A clear signal is applied to FF ₄ via O ₉ , FF ₄ becomes "L", relay circuit C ₃ stops, and motor M ₂
stops. Also, at this time, the limit switch
When LS ₃ returns, indicator light PL ₄ goes out.

Next, press switch SW ₂ and circuit A ₁ to "H"
A signal is output and added to FF ₁ as a preset signal, and FF ₁ changes to "H", which activates relay circuit C ₂ , forming the reverse circuit of motor M ₁ in Figure 38, and opening the door. Drive in the direction. When the door is completely moved, limit switch LS ₂ is activated and is applied as a clear signal to FF ₁ from circuit B ₄ via O ₆ , O ₂ , O ₃ , and the output of FF ₁ becomes "L" and the relay circuit is activated. C ₂ stops and motor M ₁ stops. Also, at this time, the limit switch LS ₁ returns to normal and the indicator light PL ₃ turns off.

In this way, the combination of each limit switch and logic circuit causes a predetermined operation to be performed when the operating switches are operated in a predetermined order, so it is possible to damage the tightening device or bolt device, or to damage each motor. This can prevent things like overheating.

When the door is running, the tightening device is operating, or the locking device is operating, operate the emergency stop switch STOP if you want to stop the operation due to an emergency need. As a result, the output of input circuit B ₁ becomes "H", and this "H" signal passes through O ₁ and then goes to O ₂ and O _3.
to FF ₁ through O ₄ , FF ₂ through O ₅ , FF ₃ through O ₈ , FF ₄ through O ₉ , FF ₅ through O ₁₃
Then, the flip-flop circuit which is in the "H" state is changed to "L" because it is applied as a clear signal to FF ₆ via _O14 , and the flip-flop circuit which is in the "H" state is changed to "L", and the door running or the tightening device is activated or the lock is activated at that moment. The operation of the device will be stopped immediately. switch
STOP is an automatic return type, but once it is pressed, it maintains the above-mentioned stopped state. When the emergency situation is resolved, normal operation can be performed by operating each of the operating switches in a predetermined order.

By the way, it is uncertain whether the flip-flop circuit will be in the "H" or "L" state when the power is turned on, and therefore, unless some measure is taken, the movement of the door and the operation of the tightening device or locking device will be affected. They may be done at the same time. Therefore, in the illustrated example, the resistors R ₁ , R ₂ ,
An initial reset circuit consisting of a capacitor C, a diode D, and an inverter _I1 is provided, and when a DC voltage Vcc is generated by operating the key switch KS, an initial reset signal is sent to each of the flip-flop circuits _FF1 to _FF6 . It is added to the clear terminal so that none of the motors M ₁ , M ₂ , and M ₃ are driven.

In the above-described operation, the movement of the door, the operation of the tightening device, and the operation of the locking device were performed by operating separate operation switches, but in the illustrated example, the operation of the switch _S1 was performed. A series of operations necessary to open the door are performed, and a series of operations necessary to close the door are performed by operating the switch _S2 .

That is, it is assumed that the door is now closed, the door is tightened by the tightening device, and the movement of the door is restrained by the bolt device, and S ₁ is operated from this state. The switch _S1 consists of three contacts, each of which is connected to each of the operating switches _SW2 ,
Since SW ₄ and SW ₆ are connected in parallel, pressing the switch S ₁ causes each of the above operation switches SW ₂ ,
This is the same state as pressing and holding SW ₄ and SW ₆ at the same time. However, as mentioned earlier, the combination of each limit switch and logic circuit operates in a predetermined order, and in this case, A ₆
-a ₄ -FF ₆ -C ₅ operates and the bolt retracts, then limit switch LS ₆ operates and changes from B ₉ to a ₂ at "H".
Since the "H" signal has been added to _a2 in advance via _A4 and _B5 , a preset signal is added from _a2 to _FF4 , and as _FF4 switches, _C3 changes. The tightening device releases the tightening, and the limit switch LS ₄ is activated to release the tightening device.
The clear signal applied to FF ₁ and FF ₂ via _B7 - _I2 is stopped _, and FF ₁ and FF ₂ become ready for presetting. At this point, a preset signal is applied from A1 to FF ₁ , C ₂ will operate and the door will move in the opening direction.

Next, when the switch S ₂ is operated from the open state of the door, the switch S ₂ consists of three contacts, and each contact is connected to each of the operating switches SW ₁ , SW ₃ , SW ₅
SW ₁ ,
Since this is the same as operating SW ₃ and SW ₅ in this order, the closing of the door, the tightening operation by the tightening device, and the locking operation by the bolt device are performed in this order.

In addition, SO ₁ in FIG. 34 is a switch that operates in conjunction with the operation of the right safety bar 66 in FIG. 26, and SO ₂ is a switch that operates in conjunction with the operation of the left safety bar 66 in FIG. 26. If switch SO ₁ operates while the door is moving in the direction of opening the entrance/exit, a clear signal is applied to FF ₂ via B ₃ −O ₇ −O ₄ −O ₅ , and C ₁ operates. stops and the door stops moving, and if switch SO ₂ operates while _the door is moving in the _closing direction _{, the}
To avoid the danger that a clear signal is applied to FF ₁ , the operation of C ₂ is stopped, and the door stops running, resulting in a human body, etc. being caught between the door and the wall. It is becoming possible to do this.

As described above, according to the present invention, power is supplied to the door via the power supply device comprising a bus bar and a sliding contact member that can slide into contact with the bus bar, so that the door travels smoothly. The power supply line does not stretch or loosen as a result of this, eliminating the inconveniences seen with conventional devices, such as the power supply line obstructing the movement of the door or walking near the door. can do.
