Description

The present invention relates to an auto-lock device that is mounted on an automatic door device that controls the opening and closing of a door by rotating a motor in a forward and reverse direction when an object such as a person is detected by a sensor, and in particular, a power supply is in a power failure state. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolysis lock type auto-lock device capable of forming an electrolysis lock type component for maintaining a door in an unlocked state and reducing manufacturing costs.

When an object such as a person is detected by an external sensor provided on the outer side of the door and an internal sensor provided on the inner side of the door, the automatic door device inputs the detection signal to a microcomputer to drive the motor. The door is opened and closed by rotating it forward and backward.

That is, the opening/closing control of the door is such that the door is opened/closed when an object such as a person is detected by an external sensor and an internal sensor provided on the outer side and the inner side of the door, respectively.
As such an automatic door device, one having an electric lock for locking the door is known (for example, refer to Patent Document 1).

According to the automatic door device described in Patent Document 1, the signal is supplied from an external timer during business hours by being installed at the entrance/exit of a cash corner of a bank, so that traffic can be passed from outside to inside. Is possible. Then, when it is outside the business hours, the signal from the external timer is turned off, and outside the business hours, the inside can pass freely, but the outside cannot pass.
In this way, the automatic lock device controls the opening and closing of the door depending on the presence or absence of the door activation signal from the external timer.

That is, specifically, when the ON signal from the external timer is input, the unlocking signal is transmitted from the electric lock control device to the electric lock by the action of the ON signal from the external timer. In addition, the object detection signal from the external sensor is accepted by the electric lock control device as an effective signal for opening and closing the door.

Further, 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. Then, in the unlocked state, an unlocking confirmation signal is transmitted from the electric lock to the electric lock control device as a signal indicating the unlocked state, and an internal sensor or an external device is operated by the action of the ON signal of the unlocking confirmation signal. When an object detection signal from any of the sensors is output, a door activation signal is transmitted from the electric lock control device to a door controller that opens and closes the door to open and close the door.

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

That is, specifically, when the off signal from the external timer is input (the on signal is not input), the electric lock control device first accepts 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 to unlock. Then, when the unlocking 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 unlocking confirmation signal, and the door activation signal is output. It is transmitted from the electric lock control device to the door controller to open and close the door.

Further, as a conventional automatic door device, in the automatic door device in which a driving force from a drive source composed of a motor is transmitted to a door via a transmission mechanism to open and close the door, a transmission mechanism is used as a motor output shaft. An electromagnetic solenoid is provided that has a disc-shaped restrained member that is axially mounted and that has a restraining rod that engages with a through hole provided in the restrained member. There is known an automatic door device having an electric lock that is unlocked by unlocking the restraint rod by retracting the restraint rod by deactivating the electromagnetic solenoid by deactivating the electromagnetic solenoid. , Patent Document 2.).

According to the automatic door device described in Patent Document 1, the electromagnetic solenoid is de-energized by turning on the opening/closing mode switch, and the door is brought into the released state to execute the energized opening/closing mode. When the open/close mode switch is turned off, the electromagnetic solenoid is energized, the door is locked, and the open/close mode for locking is executed.

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

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

The non-energized lock type electric lock is in the locked state unless the open/close mode switch is turned off to energize the electromagnetic solenoid. That is, this non-energized lock type electric lock is in an unlocked state when the opening/closing mode switch is turned on to energize the electromagnetic solenoid, and the unlocked state is maintained as long as energization to the electromagnetic solenoid is maintained. It is like this. When the opening/closing mode switch is turned off to de-energize the electromagnetic solenoid, or when the energization of the electromagnetic solenoid is stopped due to a power failure, the electromagnetic solenoid is locked.

The operation of the electric lock of the energization lock type and the electric lock of the non-energization lock type is completely opposite. Therefore, the energized lock type electric lock and the non-energized lock type electric lock are used for completely different purposes.
That is, when the power supply is operating normally, the auto-lock device of the anti-electrostatic lock type approaches the outside or inside of the doorway, and when the sensor near the doorway detects a passerby, the motor operates and the automatic door is opened and closed. It When the automatic door is opened, this electrolysis lock type auto-lock device turns off the electric lock that is in the locked state by energizing the electromagnetic solenoid by stopping the energization of the electromagnetic solenoid and unlocking the motor. Operates to move and open the automatic door.
The automatically opened automatic door is closed by the motor reversing after a certain period of time. In this way, the automatic door is locked by energizing the electromagnetic solenoid so that the automatic door does not open due to external force (such as wind pressure) after being closed.
And, this auto-stop device of the electrolytic decoupling lock type, when the automatic door is closed and the power supply to the electromagnetic solenoid is stopped due to a power failure or the like, the automatic door remains locked, and the person inside the automatic door remains locked. It is used for general doors that require the electric door to be unlocked so that it cannot be trapped and to keep the automatic door freely open by human hands.

On the other hand, the power-off lock type auto-lock device approaches the outside or inside of the doorway when the power supply is operating normally, and when the sensor near the doorway detects a passerby, the motor operates to open and close the automatic door. .. When the automatic door is opened, the power lock locking type auto-lock device stops the energization of the electromagnetic solenoid so that the locked electric lock is unlocked so that the automatic door can be opened.
The automatically opened automatic door is closed by the motor reversing after a certain period of time. Then, after the automatic door is closed, the electromagnetic solenoid is de-energized to be locked.
This power lock lock type auto-lock device keeps the automatic door locked when a power failure occurs and the electromagnetic solenoid is de-energized after the automatic door is closed. It cannot be opened to the public. It is used for automatic doors, such as ATM corners and cashing corners, which need to be kept in a locked state so that the doors cannot be opened freely when the power supply to the electromagnetic solenoid is stopped due to a power failure or the like.

As described above, the electrolysis lock type automatic lock device and the power outage lock type auto lock device perform the opposite operations, and thus have a problem that they cannot be manually opened in an emergency. ..
In addition, the electrolysis lock type automatic lock device and the power failure lock type auto lock device perform the opposite operations, and thus need to be manufactured separately, and the parts are also manufactured separately.
For this reason, it is necessary to prepare a component for the deactivation electrolytic lock type auto-lock device and a component for the power lock type auto-lock device, respectively. Have

Here, the operation of the automatic lock device 1 will be described.
The automatic door opens and closes automatically so that when a person detects an object such as a person while passing through the entrance and exit, the motor is normally rotated to open and when a person passes through the entrance and exit, the motor is rotated in reverse to close. Controlled. That is, the automatic door is in a closed state when a person does not approach the doorway when the automatic door device is powered on and the operation is in the operating state. Then, when the automatic door is in the closed state, the supply of power to the electromagnetic solenoid 6 is stopped and is in the locked state. At this time, the tip of the switch pressing screw 12 attached to the connecting plate 9 is separated from the switch operating plate 31 without coming into contact with the switch operating plate 31 of the micro switch 28 as shown in FIG. ..
Therefore, the connecting plate 9 is released from the electromagnetic solenoid 6, and the battery spring 13 provided between the wall surface 6 a of the electromagnetic solenoid 6 and the connecting plate 9 is locked between the flange 20 and the slide block 15. It is held in a state of being separated from the electromagnetic solenoid 6 by cooperation with the spring 22 fitted to the shaft 18. That is, the lock shaft 18 attached to the connecting plate 9 is in a protruding state as shown in FIG. 2, and the automatic door is in a locked state by the lock shaft 18.

Next, when an object such as a person is detected by the sensor as a person approaches the doorway, the door controller supplies power to the electromagnetic solenoid 6 based on the detection by the sensor. Then, the electromagnetic solenoid 6 supplied with the electric key operates. When the electromagnetic solenoid 6 operates, the plunger 8 moves, and the connecting plate 9 connected to the plunger 8 moves by the plunger 8.
That is, as shown in FIG. 3, the connecting plate 9 is attached to the battery spring 13 provided between the wall surface 6 a of the electromagnetic solenoid 6 and the connecting plate 9, and the lock shaft 18 between the flange 20 and the slide block 15. The repulsive force in the direction away from the electromagnetic solenoid 6 due to the cooperation with the fitted spring 22 is resisted, and the electromagnetic solenoid 6 is attracted.

When the connecting plate 9 is attracted by the plunger 8 due to the energization of the electromagnetic solenoid 6 as described above, the lock shaft 18 connected to the connecting plate 9 is retracted as the connecting plate 9 moves, and the automatic door is unlocked.

The slide block 212 of the automatic lock device 200 shown in FIG. 12 uses the same structure as the slide block 15 of the automatic lock device 1 shown in FIG. However, since the auto-lock device 1 shown in FIG. 2 is a power lock type, and the auto-lock device 200 shown in FIG. 12 is an electrolysis lock type, the case of the auto-lock device 1 shown in FIG. The mounting of the slide block 15 to the electromagnetic solenoid 6 is opposite to the mounting 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, it is possible to share objects having the same structure only by reversing the mounting directions.

Further, although 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. 12 is a power-out lock type, and the auto-lock device 200 shown in FIG.
Therefore, the position of the connecting plate 9 in the case of the automatic lock device 1 shown in FIG. 2 and the position of the connecting plate 207 in the case of the automatic lock device 200 shown in FIG. 12 are vertically opposite positions.

Further, since the auto-lock device 1 shown in FIG. 2 is a power lock type, and the auto-lock device 200 shown in FIG. 12 is an electrolysis lock type, an electromagnetic solenoid of the auto-lock device 1 shown in FIG. The operation is reversed between the case where 6 is not energized and the case where the electromagnetic solenoid 205 of the automatic lock device 200 illustrated in FIG. 12 is not energized.
Therefore, the lock shaft 18 of the auto lock device 1 shown in FIG. 2 when the electromagnetic solenoid 9 is not energized is protruding, and the lock shaft 18 of the auto lock device 200 shown in FIG. 12 when the electromagnetic solenoid 205 is not 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. It has the same length. In this way, it can be shared by simply adjusting the length of the lock shaft.

Further, due to the difference that the auto-lock device 1 shown in FIG. 2 is a power lock type, and the auto-lock device 200 shown in FIG. 12 is an electrolysis lock type, the manual unlocking of the auto-lock device 1 shown in FIG. Since the lock device 32 and the manual unlocking operation tool 234 of the auto-lock device 200 shown in FIG. 12 are reversed in operation, their configurations are different.
That is, in the case of a power lock type such as the automatic lock device 1 illustrated in FIG. 2, when the power supply to the electromagnetic solenoid 9 is stopped due to a power failure, the manual unlocking device 32 is locked and locked so that the automatic door does not open. Therefore, when it is necessary to open the automatic door, it is operated to release the lock.
On the other hand, in the case of an electrolysis lock type lock like the auto-lock device 200 shown in FIG. 12, the manual unlocking operation tool 234 unlocks the electric lock when the power supply to the electromagnetic solenoid 205 is stopped due to a power failure. Since the automatic door is unlocked, it is not used for unlocking the automatic door lock in principle. Therefore, in the case of the automatic lock device 200 shown in FIG. 12, when the electric lock cannot be unlocked for some reason (when the electromagnetic solenoid 205 is still energized), it is operated.

Further, since the auto-lock device 1 shown in FIG. 2 is a power lock type, and the auto-lock device 200 shown in FIG. 12 is an electrolysis lock type, the mounting directions of the slide block 15 and the slide block 212 are different. Since they are reversed, 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, as in the auto-lock device 1 shown in FIG. 2, the switch pressing screw 12 is attached to the electromagnetic solenoid 9, and the switch operating plate 31 is pressed by the tip of the switch pressing screw 12 to cause the switch operating plate 31 to switch the switch button. The operation of throwing in 30 cannot be performed. For this reason, in the case of the auto-lock device 200 shown in FIG. 12, the push plate 224 is attached to the connecting plate 207, the push 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 drawn. The switch button 229 is turned on.

Next, the operation of the auto lock device 200 will be described.
The automatic door opens and closes automatically so that when a person detects an object such as a person while passing through the entrance and exit, the motor is normally rotated to open and when a person passes through the entrance and exit, the motor is rotated in reverse to close. Controlled. That is, the automatic door is in a closed state when a person does not approach the doorway when the automatic door device is powered on and the operation is in the operating state. When the automatic door is in the closed state, power is supplied to the electromagnetic solenoid 205 and the electromagnetic solenoid 205 is in the locked state. At this time, the tip of the push plate 224 attached to the connecting plate 207 is in a state of being separated from the switch operating plate 230 by opening the switch operating plate 230 of the micro switch 227 as shown in FIG. ..
Therefore, the connecting plate 207 is in a state of being 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, and the slide block 212. By the cooperation with the spring 219 fitted to the lock shaft 215, the electromagnetic solenoid 205 is held in the attracted state.
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 in a locked state by the lock shaft 215.

Next, when an object such as a person is detected by the sensor when a person approaches the entrance or the like, the door controller stops the power supply to the electromagnetic solenoid 205 based on the detection by the sensor. Then, the electromagnetic solenoid 205 whose power supply 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 moves by the plunger 206.
That is, as shown in FIG. 12, the connecting plate 207 is attached to the battery spring 210 provided between the wall 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. By the cooperation with the fitted spring 219, the spring 219 moves in a direction away from the electromagnetic solenoid 205 and is separated from the electromagnetic solenoid 205.

Thus, when the connecting plate 207 is separated by the plunger 206 when the electromagnetic solenoid 205 is not energized, the lock shaft 215 connected to the connecting plate 207 retracts as the connecting plate 207 moves, and the automatic door is unlocked. It Then, in a state where the electromagnetic solenoid 205 is not energized, that is, in a state where the lock shaft 215 is retracted to unlock the automatic door, the motor operates in the normal direction to open the automatic door.
When the automatic door is opened, a person can pass through the doorway, and when a person passes through the doorway, the motor reversely operates to close the automatic door.

When the electromagnetic solenoid 205 is de-energized and the connecting plate 207 is moved away by the plunger 206 in this way, the pressing 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 micro switch 227 by the connecting plate 207.
Further, when the electromagnetic solenoid 205 is not energized, the plunger 206 moves and the connecting plate 207 moves in a direction away from the electromagnetic solenoid 205 side. Then, the tip of the push plate 224 attached to the connecting plate 207 draws the switch operating plate 230 of the micro switch 227.
Then, when the electromagnetic solenoid 205 is not energized, the plunger 206 is further attracted, and the connecting plate 207 moves in a direction away from the electromagnetic solenoid 205 side, the tip of the push plate 224 attracts the switch operating plate 230 of the micro switch 227.

When the switch operating plate 230 of the micro switch 227 is continuously attracted by the tip of the push plate 224, the switch operating plate 230 is pushed, and the switch button 229 of the micro switch 227 is turned on by the switch operating 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, the lock shaft 215 is retracted, and it is detected that the automatic door is unlocked. To do.

And the spring 219 fitted to the lock shaft 215 between the flange 217 and the slide block 212 cooperate with each other, and are kept away from the electromagnetic solenoid 205. 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 operates, 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, two urging forces of the battery spring 210 and the spring 219 are applied. The connecting plate 207 can be moved in good balance 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 slightly protrudes from the outer wall surface 212a of the slide block 212 on the side opposite to the connecting plate 207 side, as shown in FIG. Has become.
Therefore, the lock shaft 215 does not engage with the key receiving device 250 described later, and holds the automatic door in the open state.
When the connecting plate 207 is separated 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 against. That is, the switch actuation 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 operating plate 230 of the micro switch 227 is in a state of pressing the switch button 229.

As shown in FIG. 14, when the supply of power to the electromagnetic solenoid 205 is started from the state where the supply of power to the electromagnetic solenoid 205 is stopped, that is, the state where the electromagnetic solenoid 205 is off, the electromagnetic solenoid 205 turns on. ..
When the electromagnetic solenoid 205 is turned on, the electromagnetic solenoid 205 operates, 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 205a of the electromagnetic solenoid 205.
That is, the connecting plate 207 is a spring fitted to the battery spring 210 provided between the wall surface 205 a 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. 15, the electromagnetic solenoid 205 is attracted against the repulsive force in the direction away from the electromagnetic solenoid 205 in 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 projects from the outer wall surface 212a of the slide block 212 on the side opposite to the connecting plate 207, as shown in FIG. ..

When the connecting plate 207 is attracted to 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 to lock 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. It is in a state of being separated from the operating plate 230. That is, the switch actuation plate 230 of the micro switch 227 is released from the pressing force from the tip of the push plate 224, and the switch button 229 of the micro switch 227 is turned off. Therefore, the switch operating plate 230 of the micro switch 227 is in a state of being separated from the switch button 229.

First, as shown in FIG. 21, when the automatic door 81 is in the opened state, power is not supplied to the electromagnetic solenoid 205, and the connecting plate 207 is the wall surface 205 a of the electromagnetic solenoid 205 and the connecting plate 207. And the spring 219 fitted to the lock shaft 215 between the flange 217 and the slide block 212 cooperate with each other so that they are separated from each other. Therefore, the lock shaft 215 attached to the connecting plate 207 is retracted into the slide block 212.

When the automatic door 81 is closed from such a state, power is supplied to the electromagnetic solenoid 205 and the connecting plate 207 is attracted by the action of the electromagnetic solenoid 205, as shown in FIG. 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, if the power supply to the electromagnetic solenoid 205 is not cut off for some reason and the lock needs to be released in such a state, or the power supply to the electromagnetic solenoid 205 is stopped, In the case where the lock shaft 215 remains down and the lock cannot be released due to some trouble, the lock of the electric lock is released using the manual unlocking device 232.

That is, when the string 240 is pulled by hand, the pin portion 239a of the seated pin 239 to which the string 240 is attached is pulled, and the pin portion 239a is pulled into the hollow of the tubular portion 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, as shown in FIG. 23, the lock shaft 215 attached to the connecting plate 207 is retracted, and the automatic door is unlocked by the lock shaft 215.

In addition, it goes without saying that the present invention can be variously modified and implemented without departing from the spirit of the present invention.
