Description

  The present invention relates to an auto-lock device that is attached to an automatic door device that automatically opens and closes a door by rotating a motor forward and backward when an object such as a person is detected by a sensor, and the power supply is particularly in a power failure state. In particular, the present invention relates to a power failure locking type auto-lock device that can form a power failure locking type component that maintains a door in a locked state and can reduce manufacturing costs.

  When an automatic door device detects an object such as a person using an external sensor provided on the outside of the door and an internal sensor provided on the inside of the door, the detection signal is input to a microcomputer and the motor is operated. The door is controlled to open and close by rotating forward and backward.

In other words, the door opening / closing control is configured to open / close a door when an object such as a person is detected by an external sensor and an internal sensor provided on the outside and inside of the door, respectively.
As such an automatic door device, one having an electric lock for locking the door is known (for example, see Patent Document 1).

According to the automatic door device described in Patent Document 1, it is installed at the entrance and exit of a cash corner of a bank and the signal from the external timer is on during business hours. Is possible. Then, when it is outside business hours, the signal from the external timer is turned off. Outside the business hours, traffic from the inside is free, but traffic from the outside is impossible.
Thus, the auto-lock device controls the opening and closing of the door depending on the presence or absence of a door activation signal from the external timer.

  Specifically, when the ON signal from the external timer is input, the unlock signal is transmitted from the electric lock control device to the electric lock by the action of the ON signal from the external timer. At the same time, the object detection signal from the external sensor is received by the electric lock control device as an effective signal for opening and closing the door.

  The object detection signal from the internal sensor is always accepted by the electric lock control device regardless of the on / off signal from the external timer. When in the unlocked state, the unlocking confirmation signal is transmitted from the electric lock to the electric lock control device as a signal indicating the unlocked state. When an object detection signal is output from any one of the sensors, a door activation signal is transmitted from the electric lock control device to a door controller that opens and closes the door, thereby opening and closing the door.

  On the other hand, when the ON signal from the external timer is not input, transmission of the unlock signal to the electric lock is stopped by the action of the OFF signal from the external timer, and the electric lock enters the locked state. The object detection signal from is blocked and cannot be accepted by the electric lock control device. For this reason, the door is opened and closed only when an object detection signal is input from the internal sensor.

  Specifically, when the off signal from the external timer is input (the on signal is not input), first, the electric lock control device accepts it regardless of the on / off signal of the external timer. When the object detection signal from the internal sensor is input to the electric lock control device, the unlock signal is transmitted to the electric lock and unlocked. When the unlock confirmation signal is transmitted from the electric lock to the electric lock control device, the object detection signal from the internal sensor is output as the on signal by the action of the on signal of the unlock confirmation signal, and the door activation signal is generated. The door is opened and closed by being transmitted from the electric lock control device to the door controller.

  Further, as a conventional automatic door device, in an automatic door device in which a driving force from a driving source constituted by a motor is transmitted to a door via a transmission mechanism to open and close the door, the transmission mechanism is connected to a motor output shaft. An electromagnetic solenoid having a plunger with a constraining rod that engages with a through hole provided in the constrained member is provided with a disk-shaped constrained member that is attached to the shaft, and the constraining rod protrudes to engage with the through hole. There is known an automatic door device having an electric lock that performs locking and unlocks an electromagnetic solenoid to be de-energized to retract a restraining rod to release engagement with a restrained member (for example, , See Patent Document 2).

JP 2005-240273 A Japanese Patent Laid-Open No. 6-221055

  According to the automatic door device described in Patent Document 1, the electromagnetic solenoid is de-energized by turning on the open / close mode switch, the door is released, and the energized open / close mode is executed. When the open / close mode switch is turned off, the electromagnetic solenoid is energized, the door is locked, and the lock open / close mode is executed.

  In such a conventional electric lock, there are used two types, an energized lock type electric lock and a non-energized lock type electric lock. Also in the conventional automatic door device, two types, an energized locking type electric lock and a non-energized locking type electric lock, are used according to the type of the electric lock.

  The energized lock type electric lock is in an unlocked state unless the open / close mode switch is turned off to energize the electromagnetic solenoid. That is, this energized locking type electric lock is in a locked state when the electromagnetic solenoid is energized by turning on the open / close mode switch, and the locked state is maintained as long as energization to the electromagnetic solenoid is maintained. ing. When the open / close mode switch is turned off to cancel the energization of the electromagnetic solenoid, or when the energization of the electromagnetic solenoid is stopped due to a power failure, the unlocked state is established.

  Further, the non-energized lock type electric lock is in a locked state unless the electromagnetic solenoid is energized by turning off the open / close mode switch. That is, this non-energized locking type electric lock is in an unlocked state when the electromagnetic solenoid is energized by turning on the open / close mode switch, and the unlocked state is maintained as long as the electromagnetic solenoid is energized. It is like that. Then, when the open / close mode switch is turned off to cancel the energization of the electromagnetic solenoid, or when the energization of the electromagnetic solenoid is stopped due to a power failure, the locked state is established.

The operation of the energized lock type electric lock and the non-energized lock type electric lock are completely reversed. For this reason, the energized lock type electric lock and the non-energized lock type electric lock are used for completely different purposes.
In other words, when the power supply is operating normally, the stationary electrolytic lock type auto-lock device approaches the outside or inside of the doorway, and when the sensor in the vicinity of the doorway detects a passerby, the motor operates to open and close the automatic door. The When the automatic door is opened, this non-electrolytic lock-type auto-lock device switches the electric lock, which is locked by energizing the electromagnetic solenoid, to the unlocked state by de-energizing the electromagnetic solenoid. Operates to move and open automatic doors.
The automatic door that is automatically opened is closed by a reverse rotation of the motor after a certain time. As described above, after the automatic door is closed, the electromagnetic solenoid is energized and locked so that the automatic door is not opened by an external force or the like (for example, wind pressure or the like).
And when the automatic door is closed and the power supply to the electromagnetic solenoid stops after the automatic door is closed, the automatic door is locked and the person is placed inside the automatic door. It is used for general doors that need to be kept open so that the automatic door can be freely opened by human hands with the electric lock unlocked so as not to be trapped.

On the other hand, when the power supply is operating normally, the power lock-off type auto-lock device approaches the outside or inside of the entrance / exit, and when a sensor near the entrance / exit detects a passerby, the motor operates to open / close the automatic door . When the automatic door is opened, this electric power locking type automatic lock device stops the energization of the electromagnetic solenoid and puts the locked electric lock into an unlocked state so that the automatic door can be opened.
The automatic door that is automatically opened is closed by a reverse rotation of the motor after a certain time. And after an automatic door is closed, electricity supply to an electromagnetic solenoid is stopped and it will be in a locked state.
And this power outage lock type auto-lock device, when the automatic door is closed, when a power outage occurs and the electromagnetic solenoid stops energization, the automatic door remains locked and the automatic door can be freely moved by hand. Cannot be opened. Thus, it is used for automatic doors, such as ATM corners and cashing corners, which need to be kept locked so that the doors do not open freely when a power failure occurs and the electromagnetic solenoid is de-energized.

As described above, the electroless lock type auto-lock device and the power failure lock type auto-lock device have the problem that they are not devices that can be manually opened in an emergency because they perform the opposite operations. .
In addition, since the electroless lock type auto-lock device and the power failure lock type auto-lock device perform the opposite operations, they must be manufactured separately, and the components are also manufactured separately.

The slide block 212 of the auto-lock device 200 shown in FIG. 12 uses the same structure as the slide block 15 of the auto-lock device 1 shown in FIG. However, since the auto-lock device 1 shown in FIG. 2 is a power failure locking type, and the auto-lock device 200 shown in FIG. 12 is a non-electrolytic lock type, the case of the auto-lock device 1 shown in FIG. The attachment of the slide block 15 to the electromagnetic solenoid 6 and the attachment of the slide block 212 to the electromagnetic solenoid 205 in the case of the auto-lock device 200 shown in FIG.
In this way, the same configuration can be shared only by reversing the mounting direction.

2 can be used as the slide block 15 in the case of the auto-lock device 1 shown in FIG. 2 and the slide block 212 in the case of the auto-lock device 200 shown in FIG. The auto-lock device 1 shown in FIG. 6 is a power failure locking type, and the auto-lock device 200 shown in FIG.
Therefore, the position of the connecting plate 9 in the case of the auto-locking device 1 shown in FIG. 2 and the position of the connecting plate 207 in the case of the auto-locking device 200 shown in FIG.

2 is a power failure lock type, and the auto lock device 200 shown in FIG. 12 is a non-electrolytic lock type. Therefore, the electromagnetic solenoid of the auto lock device 1 shown in FIG. The operation is reversed between the case where the power is not supplied to 6 and the case where the electromagnetic solenoid 205 of the auto-lock device 200 shown in FIG.
Accordingly, the lock shaft 18 of the auto-lock device 1 illustrated in FIG. 2 when the electromagnetic solenoid 9 is not energized protrudes, and the lock shaft of the auto-lock device 200 illustrated in FIG. 12 when the electromagnetic solenoid 205 is de-energized. 215 is in a retracted state.
That is, the length of the lock shaft 18 of the auto-lock device 1 shown in FIG. 2 when the electromagnetic solenoid 9 is not energized and the lock shaft 215 of the auto-lock device 200 shown in FIG. 12 when the electromagnetic solenoid 205 is energized. The length is the same. In this way, it can be shared only by adjusting the length of the lock shaft.

2 is a power failure locking type and the auto locking device 200 shown in FIG. 12 is a non-electrolytic locking type, the manual unlocking of the auto locking device 1 shown in FIG. Since the operation of the locking device 32 and the manual unlocking operation tool 234 of the automatic locking device 200 shown in FIG.
That is, in the case of a power failure locking type like the auto-lock device 1 shown in FIG. 2, the manual unlocking device 32 is locked when the energization to the electromagnetic solenoid 9 is stopped by a power failure, and the automatic door is not opened. Therefore, when it becomes necessary to open the automatic door, it is operated to release the locking lock.
On the other hand, in the case of the electroless lock type as in the auto-lock device 200 illustrated in FIG. 12, when the power supply to the electromagnetic solenoid 205 is stopped due to a power failure, the manual unlocking operation tool 234 is unlocked, Since the automatic door is unlocked, it is not used in principle to release the automatic door locking lock. Therefore, in the case of the auto-lock device 200 shown in FIG. 12, it is operated when the electric lock cannot be unlocked for some reason (when the electromagnetic solenoid 205 is still energized).

Further, since the auto-lock device 1 shown in FIG. 2 is a power failure locking type and the auto-lock device 200 shown in FIG. 12 is an electroless lock type, the mounting direction of the slide block 15 and the slide block 212 can be changed. Therefore, the mounting position of the micro switch 28 of the auto-lock device 1 shown in FIG. 2 is opposite to the mounting position of the micro switch 227 of the auto-lock device 200 shown in FIG. .
Therefore, like the auto-lock device 1 shown in FIG. 2, a switch push screw 12 is attached to the electromagnetic solenoid 9, and the switch operation plate 31 is pressed by the tip of the switch push screw 12 to switch the switch button. The operation of throwing 30 cannot be performed. For this reason, in the case of the auto-lock device 200 shown in FIG. 12, the pressing plate 224 is attached to the connecting plate 207, the pressing plate 224 is moved by the connecting plate 207, and the switch operating plate 230 is pulled by the tip and the switch operating plate 230 is moved. A switch button 229 is input.

Next, the operation of the auto-lock device 200 will be described.
The automatic door opens and closes automatically when the person detects an object, such as a person, when the person passes the doorway, and opens the motor by rotating it forward, and when the person passes the doorway, the motor is reversely operated and closed. Be controlled. In other words, when the automatic door device is powered on and activated, the automatic door is in a closed state in a state where no person approaches the doorway. When the automatic door is in a closed state, power is supplied to the electromagnetic solenoid 205 and is locked. At this time, the front end of the push plate 224 attached to the connecting plate 207 is in a state in which the switch operation plate 230 of the micro switch 227 is opened and separated from the switch operation plate 230 as shown in FIG. .
Accordingly, the connecting plate 207 is attracted by the electromagnetic solenoid 205, and the battery spring 210 provided between the wall surface 205 a of the electromagnetic solenoid 205 and the connecting plate 207, the flange 217, the slide block 212, and the like. The magnetic solenoid 205 is held in a state of being attracted by the cooperation with the spring 219 fitted to the lock shaft 215 between the two.
That is, the lock shaft 215 attached to the connecting plate 207 is in a protruding state as shown in FIG. 13, and the automatic door is locked by the lock shaft 215.

Next, when an object such as a person is detected by the sensor, for example, when a person approaches the entrance / exit, the door controller stops supplying power to the electromagnetic solenoid 205 based on the detection by the sensor. Then, the electromagnetic solenoid 205 whose supply of power has been stopped is deactivated. When the electromagnetic solenoid 205 is deactivated, the plunger 206 moves, and the connecting plate 207 connected to the plunger 206 is moved by the plunger 206.
That is, the connecting plate 207 is attached to the battery spring 210 provided between the wall surface 205a of the electromagnetic solenoid 205 and the connecting plate 207 and the lock shaft 215 between the flange 217 and the slide block 212 as shown in FIG. It moves in a direction away from the electromagnetic solenoid 205 by cooperation with the spring 219 fitted therein, and is in a state away from the electromagnetic solenoid 205.

When the coupling plate 207 is separated by the plunger 206 while the electromagnetic solenoid 205 is not energized in this way, the lock shaft 215 connected to the coupling plate 207 is retracted along with the movement of the coupling plate 207, and the automatic door is unlocked. The Then, in a state where the electromagnetic solenoid 205 is not energized, that is, in a state where the lock shaft 215 is retracted and the lock of the automatic door is released, the motor is rotated forward to open the automatic door.
When the automatic door is opened, it becomes possible for a person to pass through the doorway, and when the person passes through the doorway, the motor reversely operates to close the automatic door.

When the electromagnetic solenoid 205 is thus de-energized and the connecting plate 207 is moved away by the plunger 206, the push plate 224 attached to the connecting plate 207 is pulled by the connecting plate 207. The push plate 224 moves so that its tip approaches the microswitch 227 by the connecting plate 207.
Further, when the electromagnetic solenoid 205 is de-energized, the plunger 206 moves, and the connecting plate 207 moves away from the electromagnetic solenoid 205 side. Then, the tip of the push plate 224 attached to the connecting plate 207 pulls the switch operation plate 230 of the micro switch 227.
When the plunger 206 is further drawn by deenergization of the electromagnetic solenoid 205 and the connecting plate 207 moves away from the electromagnetic solenoid 205 side, the tip of the push plate 224 draws the switch operation plate 230 of the microswitch 227.

If the switch operation plate 230 of the micro switch 227 is continuously pulled by the tip of the push plate 224, the switch operation plate 230 is pushed, and the switch button 229 of the micro switch 227 is turned on by the switch operation plate 230 as shown in FIG. become.
When the switch button 229 of the micro switch 227 is turned on by the switch operating plate 230, an input signal of the switch button 229 is transmitted to the door controller, and the lock shaft 215 is retracted to detect that the automatic door is unlocked. To do.

That is, the connecting plate 207 is in contact with the receiving portion 214 of the pedestal base 213.
The plunger 206 of the electromagnetic solenoid 205 is attached to the lower part of the connecting plate 207, and the connecting plate 207 moves when the plunger 206 of the electromagnetic solenoid 205 is operated, but the lock shaft 215 is attached to the upper part of the connecting plate 207. Since the battery spring 210 and the spring 219 fitted to the lock shaft 215 cooperate with each other to press the connecting plate 207, the two biases of the battery spring 210 and the spring 219 are applied. The connecting plate 207 can be moved in a well-balanced manner by the force.

When the connecting plate 207 is located away from the wall surface 205a of the electromagnetic solenoid 205, the lock shaft 215 is slightly protruded from the outer wall surface 212a of the slide block 212 opposite to the connecting plate 207 side, as shown in FIG. It has become.
For this reason, the lock shaft 215 does not engage with a key receiving device 250 described later, and holds the automatic door in an open state.
When the connecting plate 207 is away from the electromagnetic solenoid 205, the tip of the pressing plate 224 attached to the connecting plate 207 presses the switch operating plate 230 of the micro switch 227 as shown in FIG. Is pressed. That is, the switch operation plate 230 of the micro switch 227 is pressed by the tip of the push plate 224, and the switch button 229 of the micro switch 227 is turned on. Therefore, the switch operation plate 230 of the micro switch 227 is in a state where the switch button 229 is pressed.

As shown in FIG. 14, when the supply of power to the electromagnetic solenoid 205 is stopped, that is, when the supply of power to the electromagnetic solenoid 205 is started from the state where the electromagnetic solenoid 205 is off, the electromagnetic solenoid 205 is turned on. .
When the electromagnetic solenoid 205 is turned on, the electromagnetic solenoid 205 is activated and the plunger 206 is attracted, and the connecting plate 207 is attracted to the wall surface 205a of the electromagnetic solenoid 205 as shown in FIG. Then, the connecting plate 207 contacts the wall surface 205 a of the electromagnetic solenoid 205.
That is, the connecting plate 207 is a battery spring 210 provided between the wall surface 205a of the electromagnetic solenoid 205 and the connecting plate 207, and a spring fitted to the lock shaft 215 between the flange 217 and the slide block 212. As shown in FIG. 15, the electromagnetic solenoid 205 is attracted against the repulsive force in the direction away from the electromagnetic solenoid 205 due to the cooperation with 219.
Therefore, when the connecting plate 207 is attracted to the wall surface 205a of the electromagnetic solenoid 205, the lock shaft 215 protrudes from the outer wall surface 212a of the slide block 212 opposite to the connecting plate 207 side as shown in FIG. .

When the connecting plate 207 is attracted by the wall surface 205a of the electromagnetic solenoid 205 and is retracted from the receiving portion 214 of the pedestal base 213, the lock shaft 215 engages with a key receiving device 250 described later and locks the automatic door. To.
When the connecting plate 207 is attracted by the electromagnetic solenoid 205, the tip of the push plate 224 attached to the connecting plate 207 opens the switch operating plate 230 of the micro switch 227 as shown in FIG. The state is separated from the operating plate 230. That is, the switch operating plate 230 of the micro switch 227 is released from the tip of the push plate 224, and the switch button 229 of the micro switch 227 is turned off. Therefore, the switch operation plate 230 of the micro switch 227 is in a state of being separated from the switch button 229.

When the automatic door 81 is closed from such a state, as shown in FIG. 22, power is supplied to the electromagnetic solenoid 205, and the connecting plate 207 is attracted by the action of the electromagnetic solenoid 205. For this reason, the lock shaft 215 attached to the connecting plate 207 is pushed by the connecting plate 207 and protrudes from the slide block 212.
In such a state, the power to the electromagnetic solenoid 205 cannot be cut off due to some trouble, and it is necessary to release the lock in such a state, or the power supply to the electromagnetic solenoid 205 is stopped despite being stopped. When the lock shaft 215 is down and cannot be unlocked due to some trouble, the manual unlocking device 232 is used to unlock the electric lock.

That is, when the string 240 is pulled by hand, the pin part 239a of the seated pin 239 to which the string 240 is attached is pulled, and the pin part 239a is pulled into the hollow of the cylindrical part 236a of the flanged guide member 236. Then, the sliding member 238 to which the flanged guide member 236 is attached moves.
When the sliding member 238 moves, the protrusion 238a provided on the sliding member 238 moves and pushes up the manual push screw 209 that is in contact with the protrusion 238a. By pushing up the manual push screw 209, the connecting plate 207 attached to the manual push screw 209 moves in a direction away from the wall surface 205a of the electromagnetic solenoid 205.
Then, the lock shaft 215 attached to the connecting plate 207 is retracted as shown in FIG. 23, and the automatic door is released from being locked by the lock shaft 215.

  In addition, the present invention can of course be modified in various ways within the scope not changing the gist of the present invention.
