Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing body control system for controlling the operation of an opening / closing body configured to automatically close in the event of a fire or the like.
[0002]
[Prior art]
Opening / closing bodies such as shutters and doors provided at openings serving as entrances of buildings and rooms function to partition the inside and outside of buildings and rooms when in a closed state. Among these opening and closing bodies, fire shutters and fire doors designed especially for fire prevention and smoke prevention at the time of fire have a predetermined fire prevention performance, for example, by forming slats and doors thickly. The fire shutter and fire door are normally in a fully open state, and when an emergency signal is received, the fire shutter or fire door generally starts to descend or move by its own weight or a mechanical mechanism, and performs a closing operation. In some cases, even when an emergency signal is not received, the self-weight drop or the like is started by a manual operation, a fuse blow or the like. Such fire shutters and fire doors do not necessarily require an open / close device because they should drop by their own weight, etc., but they must be fully opened after installation, inspection, evacuation drills, etc. In some cases, some are equipped with a switch. In order to instruct the operation of the opening / closing switch, a control switch corresponding to each operation of the opening / closing stop is provided in the fire shutter or the fire door provided with such an opening / closing machine.
[0003]
The fire shutter and fire door described above are normally fully open and rarely perform opening and closing operations. On the other hand, it is configured to perform the same operation as the above fire shutter and fire door in the event of an emergency such as the occurrence of a fire, etc., and it controls the opening and closing of the switch by each switch such as opening and closing during normal times. However, there is a so-called management opening / closing body for closing an opening for crime prevention or partitioning, or for releasing the closure to form an opening. As such an opening / closing member for management, there is one described in Patent Document 1.

Japanese Patent Laid-Open No. 11-200745
[0004]
[Problems to be solved by the invention]
As described above, many of those that are electrically opened and closed using a switch include a wired operation switch (PBS) for controlling the operation. With an open / close body equipped with such an operation switch, the shutter curtain or door continues to be lifted or opened even when an emergency disaster signal is received during the normal operation of the shutter curtain or door being lifted or opened. However, there is a possibility that the automatic closing due to its own weight will not be started until the operation is stopped due to the fully opened state or the operation is stopped by the operation of the stop button. Therefore, in the event of an emergency such as a fire, it may take time to fully close the shutter curtain and door.
[0005]
The present invention has been made in view of the above-described points, and when an emergency automatic closing signal is received during operation of the opening / closing body, the opening / closing body capable of shortening the time required to fully close as much as possible. An object is to provide a control system.
[0006]
[Means for Solving the Problems]
The first feature of the opening / closing body control system according to the present invention is: Opening / closing body means provided in the opening, control means for controlling the opening / closing operation of the opening / closing body means, and control operation instruction means connected to the control means and outputting a signal related to the control of the opening / closing operation. In the opening / closing control system, when the emergency signal is input during the operation of the opening / closing member means in response to a signal related to the control of the opening / closing operation from the control operation instruction means, the control means controls the operation of the opening / closing member means. Stop immediately and automatically close the opening / closing means Especially is there. The operation of the opening / closing body means includes an opening operation, a closing operation, and an opening / closing operation for performing both operations. The control operation instruction means is usually composed of three push buttons, an open button, a stop button, and a close button, and is manually operated, but automatically by a timer by an automatic control device or the like. In the case of performing an opening operation and a closing operation, such an automatic control device is also included. The control means controls an opening / closing operation of the opening / closing body means, for example, an opening operation, a closing operation, and a stopping operation, according to the operation of each button of the control operation instruction means. In the opening / closing body means equipped with a self-holding circuit that maintains the operation state of the control operation instruction means, since the state is maintained during the opening operation of the opening / closing body means, even if an emergency signal is input, The automatic closing may not be started until after the upper limit stop or stop button is input to stop. Therefore, in the present invention, when an emergency signal due to the occurrence of a fire or the like is input, the operation of the opening / closing means is immediately stopped at that time, and automatic closing is performed. For example, by cutting off the power supply to the control operation instruction means, the self-holding circuit may not operate, thereby stopping the operation of the opening / closing body means. As a result, when an emergency signal is input during the opening operation as in the conventional case, it does not operate until it is fully opened, but immediately stops and starts automatic closing, thereby shortening the time until the opening / closing means is fully closed. can do. The term “automatic closing” as used herein does not include driving closing based on a power source, but means closing by self-weight drop or pure mechanical driving. The power supply is used for operations that are not related to the essential operation of automatic closing, such as braking operation for stopping halfway due to detection of an obstacle, releasing braking for subsequent re-descent, etc. Cases are included.
[0007]
A second feature of the opening / closing member control system according to the present invention is the opening / closing member control system according to the first feature. And setting means for setting so that at least the opening operation of the opening / closing operation of the opening / closing body means cannot be controlled by the control operation instruction means after the emergency signal is input. Especially is there. When an emergency signal generated from a smoke sensor, a temperature sensor, or the like is input in an emergency such as the occurrence of a fire, the setting means makes it impossible to control the opening / closing operation using the control operation instruction means thereafter. For example, the setting unit disconnects the connection between the control operation instruction unit and the control unit, cuts off the power supply to the control operation instruction unit, or the control unit ignores the control signal from the control operation instruction unit. In other words, the opening / closing operation cannot be controlled even if each button of the control operation instruction means is operated. This prevents the shutter curtain or door that is being automatically closed (descent) or fully closed from being lifted or opened. When the emergency signal is released, the setting means returns the control operation instruction means to the normal state so that the control operation instruction means can perform the opening / closing operation as usual.
[0008]
A third feature of the opening / closing member control system according to the present invention is the opening / closing member control system according to the second feature. And the setting means But And switch means for stopping power supply to the control operation instruction means in response to the input of the emergency signal Especially is there. Since the normal control operation instruction means is configured to control and maintain the opening / closing operation in a state where power is supplied, the switch means stops the power supply to the control operation instruction means, thereby The operation cannot be executed.
[0009]
A third feature of the opening / closing member control system according to the present invention is the opening / closing member control system according to the second or third feature. The control means and the control operation instruction means But The opening / closing body means is opened / closed by the power from the first power supply means, and the setting means closes the opening / closing body means by the power from the second power supply means in response to an emergency signal input. When the emergency signal is input at least during the opening operation of the opening / closing body means by the electric power from the first power supply means, the operation of the opening / closing body means is immediately performed by the control means or the setting means. Stop and perform the closing operation of the opening / closing body means by the setting means Especially is there. In the switching body control system, a commercial power source is used as the first power supply means, an emergency signal is used as the second power supply means, and the control means and the control operation instruction means are the power from the first power supply means. The setting means operates based on the power from the second power supply means. Normally, power is supplied from the first power supply means to the control means and the control operation instruction means. Therefore, if a signal relating to control of the opening / closing operation is output from the control operation instruction means to the control means. The control means opens and closes the opening / closing body means in response to the signal. Even when an emergency signal is input during the opening operation of the opening / closing body means, that is, when the power from the second power supply means is supplied to the setting means, the power from the first power supply means is controlled by the control means and the control means. Since it is supplied to the operation instruction means, the opening operation is continuously performed, and the closing operation of the setting means cannot be immediately performed. Therefore, in the present invention, when an emergency signal is input even during the opening operation, either the control means or the setting means is operated to immediately stop the operation of the opening / closing body means, and the opening / closing body by the setting means is The closing operation of the means was performed immediately. Generally, since the first power supply means consumes more power than the second power supply means, the power capacity of the first power supply means is the power capacity of the second power supply means. Is preferably larger. It should be noted that the power supply from the second power supply means may not be required at the time of self-closing due to its own weight drop or pure mechanical drive. That is, when only automatic closing is performed, the power supply capacity of the second power supply means may be zero.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of an opening / closing body control system according to the present invention will be described below with reference to the accompanying drawings. In this embodiment, a shutter device that is controlled to be opened and closed vertically will be described as an example of the opening / closing body control system. FIG. 1 is a diagram showing a schematic configuration of a shutter device according to the opening / closing body control system of the present invention.
[0011]
This shutter device is provided in an opening of a building, and basically includes a shutter case 1, a shutter curtain 2, guide rails 3, 4, a winding shaft 5, a chain 6, a motor 7, a control device 8, and an operation switch. 9 and the obstacle sensor 11. The shutter device is normally controlled to open and close by operating a motor 7 serving as an opening / closing device in response to an operation of an operation switch 9. In this shutter device, the shutter curtain 2 is held in the open state wound around the winding shaft 5 by a mechanical holding mechanism (not shown). When an emergency signal BS indicating the occurrence of a fire or the like is input from the outside to the control device 8 in this open state, the open state held by the holding mechanism is released, and the shutter curtain 2 is naturally lowered by its own weight. Thus, the opening is automatically closed.
[0012]
The guide rails 3 and 4 are provided on both ends of the opening of the building so as to be in contact with both ends of the shutter curtain 2, and have a U-shaped guide groove extending from the lintel to the floor surface. It is comprised with the metal member which has. The shutter curtain 2 moves up and down along the guide grooves of the guide rails 3 and 4 to open and close the opening. The winding shaft 5 is rotatably provided at both ends of the shutter case 1 and winds up or rewinds the shutter curtain 2. The chain 6 connects a main sprocket provided on the rotating shaft of the motor 7 and a driven sprocket provided on the rotating shaft of the winding shaft 5. Accordingly, the rotational driving force of the motor 7 is transmitted to the winding shaft 5 side via the chain 6, and when the motor 7 rotates, the winding shaft 5 rotates via the chain 6 and the opening / closing operation of the shutter curtain 2 is controlled. It has come to be.
[0013]
The control device 8 has a microcomputer configuration, and is supplied with power via a power supply line AC. The control device 8 controls the rotation of the motor 7 based on a control signal corresponding to the operation state of each operation button on the operation switch 9, or releases the holding mechanism based on the emergency signal BS.
[0014]
The operation switch 9 has an up button 9A, a stop button 9B, and a down button 9C as control switches corresponding to each operation of opening and closing, and outputs a control signal corresponding to the operation state of each button to the control device 8. .
[0015]
The emergency signal BS is a signal having a voltage of 24 [V] supplied from an external control room or the like in an emergency such as a fire. A temperature sensor or the like may be provided in the shutter case 1 in the vicinity of the opening of the lintel, that is, in the portion where the shutter curtain 2 moves up and down, together with or instead of the input of the emergency signal BS from the outside. Good. As this temperature sensor, the contact is always turned on, and when the contact reaches a predetermined temperature (any temperature in the range of 100 to 300 degrees Celsius), the contact is opened and the contact B is automatically turned off. If it is composed of a high-temperature bimetal thermostat or the like, and the contact is opened, an emergency signal BS may be output as a fire or the like has occurred. When such a temperature sensor is provided, a power source such as a battery may be provided separately from the power supply line AC in order to output a signal corresponding to the emergency signal BS inside the opening / closing body.
[0016]
The obstacle detector 11 has a transmitter provided at the lower end (seat plate) of the shutter curtain 2 and operates with a battery as a power source. When an obstacle is detected, the obstacle sensor 11 transmits a detection signal to the control device 8 by moving the seat plate switch. In addition, a return signal is transmitted during the return movement of the seat plate switch by removing the obstacle thereafter. Transmission of the signal from the transmitter of the obstacle sensor 11 to the control device 8 may be a wireless method or a wired method. In addition, a seat plate switch that moves by contact with an obstacle is provided at the lower end of the shutter curtain 2, and the tape switch provided along the height direction of the guide rail is pressed by the moving force of the seat plate at the time of obstacle contact. A configuration may be adopted, or a sensing signal may be output from the tape switch to the control means by wire. In addition, a configuration may be adopted in which a light projecting / receiving sensor such as a photoelectric tube or LED is provided in the opening, or an obstacle is sensed in a non-contact manner by image recognition or the like.
[0017]
FIG. 2 is a diagram showing a schematic configuration of the opening / closing body control system of the present invention. This switching body control system is supplied from a disaster prevention signal power source 27 using a battery as a power source, which is separate from the commercial power source, three-phase AC (R phase, S phase, T phase) of AC 200 [V] and the commercial power source. A shutter drive circuit using DC24 [V] as a drive source is provided. Each of the three-phase AC power supply lines is connected to the motor 7, and an ascending (opening) relay contact OM or a descending (closing) relay contact CM is provided in the middle thereof. The anti-phase circuit APR supplies the R-phase voltage to the operation switch 9 via the motor protector 20 when the three-phase alternating current of the R-phase, S-phase, and T-phase is correctly supplied. The anti-phase prevention circuit APR is configured not to supply voltage to the operation switch 9 when the three-phase alternating current of the R phase, S phase, and T phase is in reverse phase. The motor protector 20 is a heating detection switch provided in the motor 7 and stops supplying the R-phase voltage when the motor 7 is heated. Accordingly, when the reverse phase prevention circuit APR and the motor protector 20 are operated, power is not supplied to the operation switch 9, so that the opening / closing body control system does not operate.
[0018]
If it is a pure mechanical type that releases brakes when manual closing or fuse blows, etc. and does not perform control by obstacle detection, etc., this embodiment does not require a power supply. As described above, when the brake release operation is performed to start the descent of the dead weight, or when the operation such as the brake return at the time of obstacle detection and the brake release at the time of re-lowering is performed, a power supply that can be used even in the event of a fire is necessary. It is. As such a power supply, a commercial power supply such as a three-phase AC of AC 200 [V] is not used in principle, and the disaster prevention signal itself is used as a power supply, that is, a system different from a commercial power supply supplied from the outside of the shutter device. The disaster prevention signal power source 27 itself is used, or a standby power source unique to the shutter device is used. In this embodiment, a case where the disaster signal power supply 27 is used will be described. The disaster signal power supply 27 is normally constituted by a standby power supply such as a battery, and is supplied to the electromagnetic brake BC and the function stop switch 26 as an emergency signal BS in an emergency.
[0019]
When each relay contact OM or CM provided between the three-phase alternating current drive source and the motor 7 is closed, the motor 7 thereby causes the motor 7 to operate in the direction corresponding to the closed contact (AC200 [V] three-phase alternating current). ) Is supplied, and the raising (opening) or lowering (closing) of the shutter 2 is controlled. These relay contacts OM and CM are configured to close when the drive relay 21 for raising and the drive relay 22 for lowering are energized.
[0020]
The electromagnetic brake BC is a braking means connected to the motor 7, and releases the braking operation while the motor 7 is rotating, and executes the braking operation while the motor 7 is stopped. The electromagnetic brake BC is connected to relay contacts OM and CM via a rectifier RF and a counter CO. The rectifier RF rectifies the current supplied to the electromagnetic brake BC, and the counter CO counts the number of operations of the electromagnetic brake BC, that is, the number of opening / closing operations of the shutter 2. When the emergency signal BS is input from the disaster prevention signal power source 27 in the event of a fire or the like, the electromagnetic brake BC releases the braking operation of the electromagnetic brake BC using the power from the disaster prevention signal power source 27. The shutter curtain 2 operates so as to naturally drop by its own weight and automatically close the opening. And when the emergency signal BS from the power supply 27 for disaster prevention signals is cancelled | released, the electromagnetic brake BC comes to operate | move as usual.
[0021]
The operation switch 9 is shutter opening / closing control means, and includes an up (open) button 9A, a down (close) button 9C, and a stop button 9B. For example, when the up button 9A is operated, the drive relay 21 for opening is energized. This energization closes the relay contact (OM) provided on the power line of the motor 7, the motor 7 is driven in the opening direction, and the shutter curtain 2 rises. Then, since the self-holding relay contact 21A is closed by energization of the drive relay 21, the drive via the self-holding relay contact 21A is not required even if the lift button 9A is pressed once after the lift button 9A is pressed. The energized state of the relay 21 is maintained, and the ascending operation of the shutter curtain 2 is continued. The operation switch 9 includes such a self-holding circuit. When the shutter curtain 2 reaches the upper limit position, the contact of the upper limit switch 23 is opened, so that the drive relay 21 is deenergized and the shutter curtain 2 stops at the upper limit position.
[0022]
Similarly, when the lowering button 9C is operated, the commercial power source of AC 200 [V] is energized to the closing drive relay 22, the relay contact (CM) provided on the power line of the motor 7 is closed, and the motor 7 Is driven in the closing direction, and the shutter curtain 2 descends. Since the self-holding relay contact 22A is closed by energization of the drive relay 22, the energized state of the drive relay 22 is maintained via the self-holding relay contact 22A, and the lowering operation of the shutter curtain 2 is continued. When the shutter curtain 2 reaches the lower limit position, the lower limit switch 24 opens the contact, so that the commercial power supply to the drive relay 22 is cut off, and the shutter curtain 2 stops at the lower limit position.
[0023]
Further, when the stop button 9B is operated, the self-holding circuit is opened, and both the ascending and descending operations are stopped. The emergency switch 25 is an emergency stop switch when the shutter curtain 2 passes the upper limit switch 23 and abnormally rises.
[0024]
The function stop switch 26 is a normally closed switch provided in front of the operation switch 9 and continuously maintains the open state in response to the input of the emergency signal BS from the disaster prevention signal power source 27. Therefore, once the emergency signal BS is generated, the function stop switch 26 is kept open, and even if the operation switch 9 is operated, the power supply from the commercial power source of AC 200 [V] is cut off, and the motor 7 That is, the opening / closing body cannot be controlled. The function stop switch 26 is closed when the emergency signal BS is released.
[0025]
In FIG. 2, the obstacle detection control means is omitted, but the obstacle detection control means operates in response to the input of the detection signal and the return signal from the obstacle detector 11 when the shutter is normally opened and closed. The relay contact to be opened / closed is controlled to stop the lowering operation of the shutter curtain 2. In addition, when the emergency signal BS is generated, the power supply from the disaster signal power supply 27 causes the shutter curtain 2 during the automatic lowering to correspond to the input of the detection signal and the return signal from the obstacle detector 11. Control stop etc. The details of the obstacle detection control means are described in Patent Document 1, and are therefore omitted here.
[0026]
Next, details of the emergency signal reception processing executed by the opening / closing body control system of the present invention will be described with reference to the flowchart of FIG.
[Step S31]
When the emergency signal BS is received from the power supply 27 for the disaster prevention signal, the process is first branched depending on whether the shutter curtain 2 is being opened or closed. If it is in operation, the process proceeds to step S32. If not, the process jumps to step S33. Whether or not the opening / closing operation is being performed is determined by grasping the operation state of the motor 7 that is an opening / closing device, or an operation instruction to the motor 7 that is an opening / closing device is stored, and this storage state is stored. Judgment based on.
[Step S32]
When the shutter curtain 2 is in the open / close operation, the open / close operation is stopped. Here, both the opening and closing operations are not stopped, but may be stopped only during the ascending (opening) operation. In order to stop the operation, the electromagnetic brake BC may be operated by supplying power from the disaster signal power source 27 in response to the input of the emergency signal BS, or the operation is stopped by opening the function stop switch 26. May be. When the function stop switch 26 is opened in response to the input of the emergency signal BS, the operation switch 9 cuts off the AC 200 [V] commercial power supply to the motor 7. That is, when the emergency signal BS is input during the opening operation of the shutter curtain 2, the operation of the shutter curtain 2 is immediately stopped by the operation switch 9 or the function stop switch 26.
[0027]
[Step S33]
This process is performed both in the case where the shutter curtain 2 is not in an opening / closing operation in the previous step S31 and in the case where the operation is stopped in step S32 even when the shutter curtain 2 is in an opening / closing operation. The braking operation of the electromagnetic brake BC is canceled using the electric power of, and the automatic closing operation of the shutter curtain 2 is started.
[Step S34]
Even when the ascending button 9A of the operation switch 9 is operated during the automatic lowering, the operation is invalidated, that is, in order to prohibit the opening input of the ascending button 9A, the function stop switch 26 is opened according to the input to the emergency signal BS. Set to state. Thereby, even if each button of the operation switch 9 is operated, the operation by the button is not executed. It should be noted that this step may be omitted if the operation stop is executed by opening the function stop switch 26 in the previous step S32.
[0028]
[Step S35]
The obstacle detector 11 senses an obstacle and determines whether or not a sensing signal is output. If the sensing signal is output (yes), the process proceeds to the next step S36 and is not output ( no), jump to step S41.
[Step S36]
In the state where the emergency signal BS is generated from the power supply 27 for the disaster prevention signal, since the detection signal is output from the obstacle detector 11, the electromagnetic brake BC is operated to stop the shutter curtain 2 during the automatic lowering on the way. .
[0029]
[Step S37]
The shutter curtain 2 stopped halfway during the automatic lowering is raised by a predetermined amount. For this ascending operation, the emergency signal BS from the disaster prevention signal power source 27 may be used, a three-phase AC of AC 200 [V] may be used, or a spare battery or the like may be used separately. Good.
[Step S38]
Since the shutter curtain 2 is raised by a predetermined amount, the raising operation is stopped. This operation may be raised only for a predetermined time, or may be raised by a predetermined amount as judged from the rotational position of the motor 7. The operation of steps S37 and S38 is to make it possible to easily remove an obstacle that has contacted the shutter curtain 2. In addition, when it is desired to reduce the power supply capacity of the disaster prevention power supply or the spare battery or the power consumption of the shutter device as much as possible, the ascending operation of a predetermined amount is performed to avoid the power consumption generated for the opening direction operation of the switch and the like. Instead, it may be simply stopped. In this case, the process of step S37 and step S38 may be omitted, and the process may proceed to the obstacle removal determination process of step S39.
[0030]
[Step S39]
It is determined whether or not the obstacle has been removed by the operation in steps S37 and S38, that is, the obstacle has been removed by the reverse rise, that is, whether or not the obstacle in contact with the shutter curtain 2 has been removed. If it is determined (yes), the process proceeds to step S40, and if it is determined that it is not separated or not removed (no), the determination is repeated until the obstacle is released or removed. If this determination is repeatedly performed for a predetermined time or more, the process may proceed to step S40.
[Step S40]
Since it is determined to be yes in the previous step S39, the braking operation of the electromagnetic brake BC is canceled, and the shutter curtain 2 starts to descend its own weight again.
[0031]
[Step S41]
If the shutter curtain 2 is fully closed, that is, whether the shutter curtain 2 has reached the lower limit position and the lower limit switch 24 has opened the contact, and if it is determined to be fully closed (yes) Proceeding to the next step S42, if it is determined that it is not fully closed (no), the process returns to step S35, and the obstacle sensing process of steps S35 to S40 is repeatedly executed.
[Step S42]
Since the shutter curtain 2 reaches the lower limit position and is fully closed, the lower limit switch 24 opens the contact, the power supply to the drive relay 22 is cut off, and the shutter curtain 2 stops at this lower limit position.
[0032]
[Step S43]
Processing branches depending on whether or not the emergency signal BS has been received, that is, whether or not the emergency signal BS has been recovered. If the emergency is recovered (yes), the process proceeds to the next step S44, and if not recovered (no), the process of this step is repeated.
[Step S44]
Since the emergency has been recovered, the prohibition of input of the ascending button 9A of the operation switch 9 set in the previous step S34 is canceled. That is, since the emergency signal BS is not supplied to the function stop switch 26, the function stop switch 26 is closed, and the function of the operation switch 9 whose function is stopped becomes effective.
[0033]
In the embodiment described above, an example using hardware such as a switch has been described. However, the present invention is not limited to this, and the shutter curtain opening / closing operation may be controlled by executing software using a microprocessor. . In this case, the microprocessor or the like is operated by the power of the emergency signal BS from the disaster prevention signal power source 27. In the above-described embodiment, the operation of the shutter curtain 2 is stopped at step S32, automatically lowered at step S33, and the opening input of the ascending button 9A is prohibited at step S34. In step S32, the operation of the shutter curtain 2 may be stopped by setting the function stop switch 26 to the open state, and the automatic lowering may be performed immediately. In this case, the process of step S34 is unnecessary.
[0034]
Further, in the above-described embodiment, a normal electric shutter device has been described as an example of an opening / closing body. However, as long as the opening is closed by the operation of the automatic closing device, not only the shutter device but also a fire door, etc. Other opening / closing bodies may be used. The holding mechanism for holding the opening and closing body in an open state is not limited to the automatic closing device using the electromagnetic brake described in the above embodiment, and the release state is held by a press plate, a pulling mechanism, a magnet, and the like. It may be configured to be released by removing the presser plate by inputting the emergency signal BS.
[0035]
In the above-described embodiment, the shutter as the opening / closing body has been described as an example in which the weight is lowered. This holding mechanism is also naturally closed by the biasing force of the spring by the input of the emergency signal BS as in the above-described embodiment, and when the obstacle comes into contact during the closing, the suspension control is performed as described above. It can be. For example, in order to prevent the spring force acting in the closing direction, such an open / close door is provided with a brake mechanism that presses the door or pulls in the direction opposite to the closing direction, and this brake mechanism is operated by obstacle contact. The brake is released by releasing the contact and the biasing force of the spring is restored.
[0036]
In the above-described embodiment, the emergency signal BS of 24 [V] is input from the disaster prevention signal power supply 27. However, the present invention is not limited to this, and a normal signal input is received to switch to the emergency mode. Also good. In this case, it is necessary to mount a battery as a separate power source. Further, the input form of the signal is not limited to wired, and may be configured to include a receiving unit and be wirelessly input. Furthermore, in the above-described embodiment, the case where the emergency signal BS is input from the power supply for disaster prevention signal provided outside the shutter case in the event of a fire or the like has been described. A sensor may be provided, and the detection signal of the temperature sensor may be controlled as the emergency signal BS. Also in this case, it is necessary to mount a battery or the like as a separate power source. In the above-described embodiment, the case of using a commercial power source and a separate power source for disaster prevention has been described. However, the commercial power source may be used as a common power source.
[0037]
Further, the case where an electrical signal such as the emergency signal BS is input has been described. However, the present invention is not limited to such an input of an electrical signal. For example, the mechanical configuration is configured to release the shutter curtain from being held open. May be. In other words, if a fuse that melts in response to a fire is provided in the holding mechanism and the shutter curtain is naturally lowered when the fuse is blown, an operation similar to that when an emergency signal is detected when the fuse is blown is performed. It can also be. In addition, although the case where the obstacle is detected and paused and reversely raised has been described, only the pause may be used, or the reverse rise and fall may be repeated several times. Further, in the above-described embodiment, the power supply to the operation switch is cut off so that the opening / closing operation cannot be controlled even if each button of the operation switch is operated. It goes without saying that processing may be performed by software so that the connection with the device is disconnected or the operation command from the operation switch is ignored on the control device side.
[0038]
