The open / close body device such as the fire shutter device 10 is provided with a disaster prevention signal BS (for example, a 24V DC signal or no signal) from the sensor 15 (or an interlock controller connected to the sensor or a disaster prevention panel) that senses smoke or heat generated in the event of a fire. In response to the output of the voltage a contact ON signal), an automatic closing device 3 for releasing the brake 2 connected to the switch 1 is provided. The voltage value of the signal may not be 24 V, and the voltage value is determined as appropriate. The opening / closing machine 1 is a drive motor for driving the shutter curtain 4. The harmless interlocking repeater 5 outputs a DC 24V signal to the automatic closing device 3 when the disaster prevention signal BS is input. The harm prevention interlocking repeater 5 normally outputs using a commercial power supply 16, but outputs a DC 24V signal by power from a built-in standby power supply (battery such as a storage battery) at the time of a power failure or the like. . The automatic closing device 3 depends on the power (DC 24V signal) from the commercial power supply 16 supplied via the harm prevention interlocking relay 5 or the standby power supply (storage battery) built in the harm prevention interlocking relay 5. Operate.

  The automatic closing device 3 is connected to the sensor 15 (or the interlock control with the sensor connected) even if there is no supply of commercial power to the fire prevention shutter device 10 in the event of a fire due to the standby power source built in the interlock device 5 for hazard prevention. The brake 2 is released based on a disaster prevention signal BS input from a device, a disaster prevention board, etc.), and the shutter curtain 4 having a fire prevention structure in a wound state is lowered by its own weight so that the opening can be automatically closed. It has become. The automatic closing device 3 includes a device configured to mechanically transmit power from the automatic closing device 3 to the brake 2 and to release or return the brake with the power. There is a configuration in which a command signal for instructing release is output, and the brake 2 is configured to electrically release or return the brake in accordance with the input command signal. In an emergency, the automatic closing device 3 lowers the shutter curtain 4 by its own weight according to the operation of the electric manual closing device 7 (emergency shutter closing button 8). The automatic closing device 3 releases the brake 2 while there is power supply (DC 24V signal) from the harm prevention interlocking repeater 5, but when there is an obstacle detection signal from the wired obstacle detection device, Meanwhile, the brake 2 is returned. In some cases, the brake is restored when the power supply (DC 24V signal) is lost from the harm prevention interlocking relay 5.

  The electric manual closing device 7 controls a DC 24V signal output from the harm prevention interlocking repeater 5 according to the operation of the emergency shutter closing button 8. The electric manual closing device 7 includes an input switch (push button switch) corresponding to the opening / closing stop of the switch 1, an operation button and a recovery button (not shown).

  FIG. 2 is a diagram showing a schematic configuration of the harm prevention interlocking repeater 5 of FIG. As shown in FIG. 2, the harm prevention interlocking repeater 5 includes a power supply circuit 51, a charging device 52, a standby power supply (storage battery) 53, a power supply switching device 54, and a control circuit 55. The power supply circuit 51 converts the commercial power supply 16 into a DC 24V signal, supplies a DC voltage to the control circuit 55 via the power supply switching device 54, and supplies power to the charging device 52. The charging device 52 charges the standby power supply (storage battery) 53 using the power from the power supply circuit 51. The standby power supply (storage battery) 53 is composed of a lithium ion rechargeable battery or other batteries, and supplies a direct-current voltage to the control circuit 55 via the power supply switching device 54. The power supply switching device 54 selectively switches one of the power supplies of the power supply circuit 51 and the standby power supply 53 and connects it to the control circuit 55. Normally, since the power from the commercial power supply 16 is supplied, the DC voltage from the power supply circuit 51 is supplied to the control circuit 55, but the power supply from the commercial power supply 16 is stopped in an emergency such as the occurrence of a fire. In some cases, the DC voltage from the standby power supply 53 is supplied to the control circuit 55. The return switch 56 is a switch for resetting the operation of the control circuit 55.

  In this way, the standby power supply 53 built in the hazard prevention interlocking repeater 5 allows the sensor 15 (or the interlocking controller connected to the sensor or On the basis of the disaster prevention signal BS input from the disaster prevention panel or the like to the control circuit 55, an operation signal (DC 24V signal) is output from the harm prevention interlocking repeater 5 to the automatic closing device 3, and the automatic closing device 3 releases the brake 2. By releasing, the shutter curtain 4 having a fire-proof structure in the wound state can be lowered by its own weight to automatically close the opening. In an emergency, by operating the electric manual closing device 7 (emergency shutter closing button 8), an operation signal (DC 24V signal) is also output from the control circuit 55, and the shutter curtain 4 is lowered by its own weight. Can do.

The fire shutter device 10 is provided with an obstacle sensing device that detects contact with an obstacle during opening and closing. As shown in the figure, the obstacle sensing device includes a seat switch 9 provided on the seat plate at the lower end of the shutter curtain 4, a wired obstacle sensing device 17 provided in the storage box of the shutter curtain 4, and these And a signal cord 11 that electrically connects the two. The seat plate switch 9 is attached to the seat plate of the shutter curtain 4 and has a built-in micro switch that closes the contact point when the seat plate comes into contact with an obstacle such as a person or an object. Then, it is transmitted as a sensing signal to the wired obstacle sensing device 17 via the signal code 11 in a wired manner. The signal code 11 is a cable that transmits the sensing signal of the seat board switch 9 to the wired obstacle sensing device 17. The cable is housed or guided by a cord reel, a movable pulley, or the like, so that it does not bend to obstruct the opening and closing of the shutter curtain 4. The wired obstacle sensing device 17 controls the operation of the switch 1 according to the input of a sensing signal from the seat board switch 9. The automatic closing device 3 returns the brake 2 in response to the input of a sensing signal from the wired obstacle sensing device 17 and controls to stop the closing operation of the shutter curtain 4. Therefore, when the shutter curtain 4 is lowered by its own weight in the event of a fire, the seat plate or the like comes into contact with an obstacle, and when the sensing signal is detected from the seat plate switch 9, the lowering of the weight of the shutter curtain 4 is stopped. It has become. The limit switch 12 is a switch for stopping the shutter curtain 4 at the upper limit and the lower limit. An example of such a fire shutter device is disclosed in Patent Document 1.
JP 2002-81281 A

In the conventional fire shutter device as described above, the wired obstacle sensing device 17 determines that an abnormality has occurred when the signal cord 11 that transmits the signal from the seat switch 9 is disconnected, and notifies the user or the like with a buzzer. Or, the opening / closing operation of the shutter curtain 4 is controlled by operating the emergency shutter closing button 8 of the electric manual closing device 7 and / or the control by operating the opening / closing button is set to a mode different from the normal mode such as the push-off operation mode. Accordingly, the user can recognize the abnormality by operating. The push-off operation mode here is, for example, that the operation is maintained while the button is operated by pressing the button, but the operation is stopped accordingly when the operation is stopped by releasing the button, for example. It is an operation mode. After such an abnormality as the disconnection of the signal cord 11 is detected, the user is replaced with a normal one in which the signal cord 11 is not disconnected, and the normal connection with the seat plate switch 9 is wired. When the obstacle sensing device 17 recognizes, the wired obstacle sensing device 17 adopts a method of canceling (resetting) the abnormality.
However, the disconnection of the signal cord 11 may be caused by mechanical fatigue of the cord itself due to the signal cord 11 expanding or contracting according to the opening / closing operation of the shutter curtain 4. In such a case, the signal cord 11 is in a state of being cut off, and the signal lines are alternately contacted and non-contacted according to the opening / closing operation thereof. Even if it is recognized that there is an abnormality in a stable state, depending on the subsequent contact state, there is a possibility that the abnormality is canceled and the normal operation of the shutter curtain can be performed.

  An object of the present invention is to provide an opening / closing body device configured so that a sensing signal output from an obstacle sensing means such as a seat plate switch can be normally transmitted via wiring means.

The first feature of the opening / closing body device of the present invention is that the opening / closing body means provided at the peripheral edge of the opening, and an obstacle on the moving path when the opening / closing body means is moving, And obstacle control for causing the opening / closing body means to perform an avoiding operation in response to the sensing signal when the obstacle sensing means detects an obstacle on the operation path of the opening / closing body means Means, wiring means for transmitting the sensing signal when the obstacle sensing means senses an obstacle to the obstacle control means, and the wiring means normally transmits the sensing signal to the obstacle control means And determining means for maintaining the determination of the impossibility without performing the determination until a predetermined operation is performed after the determination. There is.
Opening / closing body means can be used to open and close doors and windows, or openings such as internal passages and spaces in structures such as buildings, houses, factories, and warehouses, or shutter curtains that only move closed It is made up of an opening and closing member and a closing member, and is extended to partition the opening for fire prevention, smoke prevention, waterproofing, windproofing, crime prevention, etc. in the event of a disaster or closing. When the opening / closing means is, for example, a fire prevention / smoke prevention shutter curtain for forming a fire prevention section, the fire prevention shutter curtain is stored in an upper part which is one of the peripheral parts of an opening of a building or the like and passes through a lintel etc. Descends and closes the opening. In addition to this, the opening / closing body means may be housed in the side portion of the opening and opened / closed by a horizontal pulling method, or may be housed in the lower part of the opening and opened / closed by an ascending method. The opening / closing body means includes those that can be fully closed by closing and those that cannot be fully closed.
In such fire shutter curtains and the like, as an example, obstacle sensing means for detecting contact with obstacles during opening and closing is provided on the seat plate at the front end of the closed side, and by detecting obstacles, The shutter curtain is designed to perform the avoidance operation. The avoidance operation here includes a case where the descent of the shutter curtain is stopped, the descent speed is suppressed without reaching the stop, or the shutter curtain is raised reversely from the sensed state. . In addition, the obstacle sensing means includes a contact type sensor provided on a seat plate or the like at the front end of the closed side and a non-contact type sensor such as an area sensor. Accordingly, the shutter curtain performs an avoidance operation when the seat plate comes into contact with an obstacle while the shutter curtain is moving under its own weight during automatic closing.
Thus, in order for the obstacle sensing means provided at the closed end or the like to operate normally while the shutter curtain is descending, the sensing signal is sent from the obstacle sensing means to the obstacle control means via the wiring means. It is necessary to communicate normally. That is, if it is once determined by the determination means that it is impossible to transmit normally (abnormal), there is a possibility that some trouble has occurred in the transmission means. However, there is no guarantee that the normal state will continue, and it may be determined as abnormal at any time. Therefore, in the present invention, when it is determined by the determination means that the wiring means cannot normally transmit the sensing signal, the determination is made without performing the determination until a predetermined operation is performed after the determination. I tried to keep it. The predetermined operation here means an operation such as a maintenance check and replacement work of the wiring means, and when this operation is completed, it is determined whether it is normal or abnormal. The opening / closing body device can perform a normal opening / closing operation in a state where a sensing signal output from an obstacle sensing means such as a seat plate switch can be normally transmitted via the wiring means. After performing maintenance inspections and replacement work for the wiring means, turn on the power again or perform a reset operation so that the predetermined operation such as maintenance inspection and replacement work for the wiring means is completed. May be.

A second feature of the opening / closing body device according to the present invention is that in the opening / closing body device according to the first feature, when the determination unit determines that the determination is impossible, the determination result indicating the impossibility is displayed in a visible manner. The display means to be provided.
In the present invention, when the determination means determines that the wiring means cannot normally transmit the sensing signal (that is, abnormal), the information is displayed in a visible manner, and the wiring means needs to be inspected or replaced. The manager is notified at an early stage that it has become.

According to a third feature of the opening / closing body device of the present invention, in the opening / closing body device according to the first feature, the opening / closing body means is closed in response to an input of an artificial operation signal and a signal different from the operation signal. An automatic closing means to be operated, a power supply means for supplying electric power to the obstacle sensing means, and an operator means provided in the casing, the transparent panel capable of being pushed and broken provided in a part of the casing The operation means that outputs the operation signal by being manually operated via a display, and the remaining capacity of the electric capacity of the power supply means provided in the housing so as to be visible through the transparent panel In addition, there is provided display means for displaying the determination result of the impossibility so as to be visible when the determination means determines the impossibility.
The artificial operation signal input to the automatic closing means is generated when the operation means such as an emergency shutter closing button provided in the housing is artificially operated. Usually, since a transparent panel that can be pushed through is provided in a part of the casing, the operator means is manually operated by outputting the transparent panel and outputs an operation signal. Moreover, as a signal different from the operation signal, there is a disaster prevention signal or an emergency closing signal generated in the event of a fire or the like. By inputting these signals, the automatic closing means lowers the fire shutter curtain and closes the opening.
The present invention displays that the remaining amount of electric capacity of the power source means such as a standby power source has been reduced (including disappearance) and the determination result that is impossible when the determination means determines impossible (abnormal) Display means is provided in a housing housing the emergency shutter closing button at a position where it can be seen through a transparent panel that can be pushed through provided in a part of the housing. The display means promptly notifies the manager or the like that inspection or replacement of power supply means such as a standby power supply or wiring means is necessary. In this way, by using the transparent panel of the existing casing, the display means can be provided so as to be visible without any special processing or the like for providing the display means, and the design of the casing itself is also improved. Can be improved.

According to a fourth feature of the opening / closing member apparatus of the present invention, in the opening / closing member device according to the third feature, the display means is in the vicinity of the operator means means and is visible through the transparent panel. It is to be provided at a position.
In this case, the display means is provided in the vicinity of the operator means which is an emergency shutter closing button in the housing. By providing in the vicinity of the operator means, visibility from the transparent panel is improved.

According to a fifth feature of the switchgear device of the present invention, in the switchgear device according to the third feature, the operator means itself serves as the display means and the remaining electric capacity of the power supply means and the impossibility. The determination result is displayed so as to be visible through the transparent panel.
This is because the visibility from the transparent panel is further improved by constructing the display means integrally with the operator means which is an emergency shutter closing button.
According to a sixth feature of the switchgear device of the present invention, in the switchgear device described in the third, fourth or fifth feature, at least two of the power supply means are provided, and two power supply means are provided in different systems. An opening / closing body device configured to supply electric power to the automatic closing means and the obstacle sensing means.
In this system, two power supply means are provided, and power is supplied to the automatic closing means and the obstacle sensing means in different systems. By providing at least two power supply means in this way, even if one power supply means cannot be used due to its life or cannot be used due to some trouble, power can be supplied from the other power supply means. Operational safety can be increased. Further, by alternately exchanging the two power supply means at about half of their lifetimes, it is possible to reduce the occurrence of the end of the life of the power supply means.
It should be noted that the wording “displayably visible” described in each feature of the opening / closing body device of the present invention is only required to be indirectly visible, and it is only necessary to visually recognize the display content by reflection, transmission, semi-transmission, etc. Including things. The display mode may be any type, for example, a display based on the presence or absence of light emission (or brightness), a display based on a difference in the flashing mode of light, a display based on a difference in color development, or a difference in direction. There are various things such as display, display due to differences in shape (projection size of protrusions, etc.), display due to differences in display characters (symbols) and display modes, display due to meter display and display due to differences in movement, etc. By displaying simply by the presence or absence of light emission, there is an advantage that a complicated structure is not required and visibility is good.

  According to the opening / closing body device of the present invention, there is an effect that the sensing signal output from the obstacle sensing means such as the seat plate switch can be normally transmitted via the wiring means.

  Hereinafter, a fire shutter device will be described as an example of an opening / closing device according to the present invention with reference to the accompanying drawings. FIG. 3 is a view showing a schematic configuration of a fire shutter device which is an opening / closing body device according to the present invention. This fire-proof shutter device is normally in an open state in which the opening / closing machine 1 basically winds up the shutter curtain 4. This open state is maintained by being mechanically held by the brake 2. In the event of a fire, the automatic closing device 3 receives a disaster prevention signal BS or electric signal from the sensor 15 (or an interlocked controller connected to the sensor, a disaster prevention panel, etc.) input via the harm prevention interlocking relay 3. In response to an operation signal of the manual type manual closing device 7 (emergency shutter closing button 8), the release state of the brake 2 is released and the shutter curtain 4 is naturally lowered by its own weight, thereby closing the opening, It is designed to form a fire protection zone. The detector 15 for outputting the disaster prevention signal BS to the interlocking device for preventing harm, the interlocking controller connected to the detector, the disaster prevention panel, and the like are appropriately selected and provided depending on the installation environment. Multiple sensors may be provided, but when one or more of the multiple sensors are detected, the number of disaster prevention signals corresponding to the detection of multiple disaster prevention BSs is input to the hazard-prevention interlocking relay Alternatively, a single disaster prevention signal BS may be input to the hazard-prevention interlocking relay when one or more of a plurality of sensors or the like are detected. The disaster prevention signal BS output from the interlock controller connected to the disaster prevention panel or sensor is often a voltage signal such as DC 24V, but the disaster prevention signal BS output from the sensor is a non-voltage signal. Therefore, the harm prevention interlocking repeater can be appropriately adapted to the inputted disaster prevention signal BS.

  The opening / closing machine 1 is a drive motor for opening and closing the shutter curtain 4 electrically. If it is not necessary to open and close the shutter curtain 4 during normal operation, the shutter curtain 4 may be configured only by the brake 2 instead of the switch 1 and the brake 2 which are driving sources as shown in the figure. . The harmless interlocking repeater 5 outputs a DC 24V signal to the automatic closing device 3 when the disaster prevention signal BS is input. The harmless interlocking repeater 5 normally outputs a DC 24V signal using the commercial power supply 16, but in the event of a power failure or the like, the DC 24V is supplied by power from a built-in standby power supply (battery such as a storage battery). Output a signal.

  The automatic closing device 3 depends on the power (DC 24V signal) from the commercial power supply 16 supplied via the harm prevention interlocking relay 5 or the standby power supply (storage battery) built in the harm prevention interlocking relay 5. Operate. Further, the automatic closing device 3 is provided with a disaster prevention signal inputted from the sensor 15 or the like by a standby power supply built in the harm prevention interlocking repeater 5 even if no commercial power is supplied to the fire prevention shutter device 10 in the event of a fire. The brake 2 is released based on the BS, and the shutter curtain 4 having a fire prevention structure in the winding state is lowered by its own weight so that the opening can be automatically closed. Further, the automatic closing device 3 lowers the shutter curtain 4 by its own weight in response to an operation of the electric manual closing device 7 (emergency shutter closing button 8) in an emergency.

  The electric manual closing device 7 controls the DC 24V signal output from the harm prevention interlocking repeater 5. The electric manual closing device 7 includes an input switch (push button switch) corresponding to an open / close stop of the switch 1, an operation button which is an emergency shutter closing button, a recovery button, a battery test button, and the like, and further a battery test. Various display means for displaying the result, displaying the state of the standby power supply, and displaying the code disconnection state are provided.

  In this embodiment, a hazard control interlocking repeater 5 has a first control circuit that operates in response to an input of the disaster prevention signal BS, and an operation signal for the electric manual closing device 7 (emergency shutter closing button 8). The second control circuits that operate in response to the inputs are provided independently of each other. The electric manual closing device 7 is covered with a resin-made transparent panel (push-break cap), and can be operated by pressing the resin-made transparent panel in an emergency. ). Detailed configurations of the harm prevention interlocking relay 5 and the electric manual closing device 7 (emergency shutter closing button 8) will be described later.

  The fire shutter device 10 is provided with an obstacle sensing device that detects contact with an obstacle during opening and closing. As shown in the figure, the obstacle sensing device includes a seat switch 9 provided on the seat plate at the lower end of the shutter curtain 4, a wired obstacle sensing device 17 provided in the storage box of the shutter curtain 4, and these And a signal cord 11 that electrically connects the two. The seat plate switch 9 is attached to the seat plate of the shutter curtain 4 and has a built-in micro switch that closes the contact point when the seat plate comes into contact with an obstacle such as a person or an object. Then, it is transmitted as a sensing signal to the wired obstacle sensing device 17 via the signal code 11 in a wired manner. The signal code 11 is a cable that transmits the sensing signal of the seat board switch 9 to the wired obstacle sensing device 17. The cable is housed or guided by a cord reel, a movable pulley, or the like, so that it does not bend to obstruct the opening and closing of the shutter curtain 4.

  FIG. 4 is a diagram for explaining the principle of disconnection detection when the signal code is disconnected. Both ends of the seat plate switch 9 are connected to connection terminals of the connector 41, respectively. The signal lines 111 and 112 of the signal cord 11 are connected to the connection terminals of the connector 42, respectively. A resistor 115 having a resistance value of about 51 [kΩ] is connected in parallel with the seat plate switch 9 between the signal line 111 and the signal line 112. The wired obstacle sensing device 17 detects the current flowing between the signal lines 111 and 112 of the signal code 11 with a built-in microcomputer, and the current value is a specified current value (the resistance value of the resistor 115 is 150 [kΩ]. The current value in the above case) In the following case or when no current can be detected, it is detected that the signal code 11 is disconnected. In addition, what is necessary is just to determine these resistance values suitably so that the presence or absence of a disconnection can be detected.

  The wired obstacle sensing device 17 is normally operated by a commercial power supply, controls the operation of the switch 1 in response to the input of a sensing signal from the seat plate switch 9, and at least in the event of an emergency such as a fire. The obstacle detection signal from the plate switch 9 is through-outputted to the automatic closing device 3. The automatic closing device 3 stops the closing operation of the shutter curtain 4 according to the input of the obstacle detection signal from the wired obstacle detection device 17 and performs the avoidance operation. Therefore, when the shutter curtain 4 is lowered by its own weight in the event of a fire, if the seat plate or the like comes into contact with an obstacle and a detection signal is detected from the seat plate switch 9, the weight reduction of the shutter curtain 4 is stopped. The avoidance operation is performed. That is, when the obstacle detection signal is input while the shutter curtain 4 is being lowered, the wired obstacle detection device 17 normally performs control to stop the lowering operation of the shutter curtain 4 and raise it for a certain time. On the other hand, the wired obstacle detection device 17 detects the obstacle when the automatic closing device 3 is activated and an obstacle detection signal is input while the shutter curtain 4 is descending, such as when disaster prevention occurs. A signal is transmitted through to the automatic closing device 3, the operation of the automatic closing device 3 is stopped, the release state of the brake 2 of the switch 1 is returned, and the shutter curtain 4 is temporarily stopped. The limit switch 12 is a switch for stopping the shutter curtain 4 at the upper limit and the lower limit.

  The control of lowering the dead weight of the fire shutter device 10 is performed by an opening / closing body control system configured by the interlocking relay 5 for preventing harm and the automatic closing device 3. The interlocking relay 5 for hazard prevention controls the power supply to the automatic closing device 3, and the automatic closing device 3 operates according to the power supply from the interlocking relay 5 for hazard prevention and is released by a brake. The state is released and the shutter curtain 4 is naturally lowered by its own weight.

  FIG. 5 is a flowchart showing an example of the operation of the wired obstacle sensing device of FIG. First, in step S51, the wired obstacle sensing device 17 detects the current value of the signal cord 11 shown in FIG. 4, calculates a resistance value based on the current value, and the resistance value is a predetermined specified value ( If the resistance value is greater than or equal to the specified value (yes), the process proceeds to the next step, and if not (no), the process returns to perform this cable disconnection determination process. Run repeatedly. In this step S51, the cable disconnection determination may be performed continuously with a constant current flowing, or the cable disconnection determination may be performed with a current flowing at predetermined intervals.

  In step S52, based on the result of the determination in step S51, it is determined that the current signal code 11 is in a disconnection abnormal state, and appropriate processing is executed accordingly. For example, the user is notified with a buzzer, the opening / closing operation of the shutter curtain 4 is controlled by operating the emergency shutter closing button 8 of the electric manual closing device 7 and / or the control by operating the opening / closing button is pushed out. In this embodiment, an LED for informing the disconnection of the signal cord 11 is lit in the vicinity of the emergency shutter closing button 8 of the electric manual closing device 7. .

  In step S53, it is determined whether or not the power is turned on again. When the power is turned on again (yes), the process proceeds to the next step S54. Repeat the determination process. That is, by the process of this step, the determination of the disconnection abnormality is continued until the signal code 11 determined to be the disconnection abnormality is replaced and the power is turned on again. In the case of a disconnection abnormality, the notification may be continued by supplying power to the notification unit while holding the determination of the disconnection abnormality, or until the maintenance and replacement work of the wiring means starts. Alternatively, the notification may be automatically terminated when a predetermined time has elapsed. In addition, while holding the disconnection abnormality determination, it is preferable not to supply power to the cable until a predetermined operation such as a maintenance check or replacement work of the wiring means is completed.

  In step S54, since the power is turned on again, the current value of the signal code 11 shown in FIG. 4 is determined in the same manner as in step S51 in order to determine whether or not the replacement work of the signal code 11 has been normally completed. Detect and calculate a resistance value based on the current value, determine whether the resistance value is a predetermined specified value (about 150 [kΩ]) or less, and if the resistance value is less than the specified value (yes) Then, the process proceeds to the next step S55 so that the normal operation can be performed. If not (no), the process returns to step S52 to execute a process for notifying that the signal code 11 is abnormal in disconnection.

  As described above, in this embodiment, when the disconnection abnormality of the signal code 11 is detected even once in the processing of Step S51 and Step S52, the determination of the disconnection abnormality in Step S52 is held. The process of notifying the disconnection abnormality to the user or the like is continued or performed again. Therefore, even if the signal code 11 is in a state of being cut off and the signal lines are alternately contacted and non-contacted alternately according to the opening / closing operation, the signal code 11 is determined to be broken and is continuously notified. Thus, it is possible to prevent the fire shutter device from operating in an unstable state. In addition, when the signal cord 11 is exchanged, it is also determined whether or not the exchange operation has been completed normally, so that a wiring mistake or the like during the exchange operation of the signal cord 11 can be prevented.

The disaster prevention interlocking repeater 5 receives a disaster prevention signal 6d from a disaster prevention interlocking repeater (not shown) via a terminal block 6c. Further, a fully closed signal 6e and a power supply abnormality signal 6f are output to the harm prevention interlocking relay device 5 via the terminal block 6c. In addition, a power supply abnormality indicator lamp may be provided in the vicinity of the battery test indicator lamp 83 of the electric manual closing device 7 so as to be lit and displayed using the power abnormality signal 6f. The standby power supply 53 is composed of a battery such as a storage battery, and is normally in a state in which it can be sufficiently charged, such as being in a charged state. And is connected to the harm prevention interlocking repeater 5 via the connector 53a. In addition, in FIG. 6, the connection relationship regarding the output of the operation signal output from the harm prevention interlocking repeater is not shown.

  7 and 8 are diagrams showing an example of the electric manual closing device of FIG. 3 provided with a remaining amount indicator lamp, and FIG. 7 shows a state in which the lid of the electric manual closing device 7 is closed, FIG. 8 is a view showing a state in which the lid of the manual closing device is opened. As shown in the figure, the manual closing device 7 includes a metal casing 71 and a lid 72. The lid 72 has a security key 73 and a resin transparent panel (pull-off cap) 74 that allows the emergency shutter closing button 8 provided inside the housing 71 to be seen from the outside. This resin-made transparent panel 74 is configured to be easily broken by a hand or the like in an emergency. Further, the transparent panel 71 and the emergency shutter closing button 8 are disposed in such a positional relationship that the emergency shutter closing button 8 can be pressed through the transparent panel 71 that has been pushed through. The emergency shutter closing button 8 is a red push button. An open button 62, a close button 63, and a stop button 64 for controlling opening / closing of the shutter curtain 4 are provided inside the casing 71 of the manual closing device 7. When the emergency shutter closing button 8 is pressed, the shutter curtain 4 is in its own weight closed state, so that the opening / closing control by the opening button 62, the closing button 63, and the stopping button 64 cannot be performed as usual. Therefore, a recovery button 81 is provided to end the self-weight closed state and perform open / close control by the open button 62, the close button 63, and the stop button 64. In addition, a battery test button 82 for checking the battery state (capacity) of the standby power supply 53 built in the harm prevention interlocking repeater 5 is provided.

  The remaining amount indicator lamp 14 is composed of an LED or the like, and the LED blinks or lights to indicate that the electric capacity has decreased. The battery test indicator lamp 83 is also composed of an LED or the like. The LED blinks or lights up to indicate whether the battery check is successful or not. In this embodiment, as shown in FIG. 7, even when the lid 72 is closed, the lighting state of the remaining amount indicator lamp 14 can be confirmed from the outside through the transparent panel 74. In addition to this LED, a plurality of battery-shaped display units may be provided, and the display state of the display unit may be changed according to the electric capacity so that the state can be confirmed through the transparent panel 74. In this case, the power source for operating the remaining amount indicator lamp 14 uses the commercial power source 16 and / or the standby power source 53 to determine whether power is supplied from the commercial power source 16 and / or the standby power source 53. It becomes possible. Moreover, although the case where the remaining amount indicator lamp 14 and the battery test indicator lamp 83 are provided separately has been described, the remaining amount indicator lamp 14 may be used also as the function of the battery test indicator lamp 83. Furthermore, the function of displaying the code disconnection state may be combined. Note that the display unit only needs to be directly or indirectly visible, and may be capable of visually recognizing display contents by reflection, transmission, semi-transmission, and the like. The display mode may be anything as long as it can be visually recognized. For example, the display is based on the presence or absence of light emission (or brightness), the display is based on the flashing mode, the display is based on the color difference, Various display such as display by difference in direction, display by difference in shape (such as the size of protrusion of protruding piece), display by difference in display character (symbol) and display mode, display by meter display and display by difference in movement As shown in this embodiment, a simple display with or without light emission has an advantage that a complicated structure is not required and visibility is good. In addition to the transparent panel configured to operate the emergency shutter closing button 8 indirectly through the transparent panel by pressing the transparent panel in an emergency, the transparent panel is operated by the emergency shutter closing button. The emergency closing button 8 can be directly operated after moving to a place that does not interfere with the operation (turning, removing, sliding along the lid 72, pressing the emergency shutter closing button 8 without operating, etc.). A transparent panel may be used.

  FIG. 9 is a diagram showing another embodiment of the fire shutter device of FIG. In this fire prevention shutter device, the control circuit that operates in response to the input of the disaster prevention signal BS and the operation signal of the electric manual closing device 7 (emergency shutter closing button 8) are input to the hazard prevention interlocking relay 5. Control circuits that operate accordingly are provided independently of each other. In FIG. 3, the disaster prevention signal BS (for example, the no-voltage a contact ON signal) from the sensor 15 is illustrated as being input to the harm prevention interlock repeater. However, in FIG. The operation signal (for example, DC 24V signal) from the interlock controller 29 to which the sensor 15 is connected is shown as being input to the hazard prevention interlock repeater. It is also possible to replace the interlock controller 29 connected to the sensor 15 with a disaster prevention panel.

  The harmless interlocking repeater 5 is supplied with a commercial AC power source (AC 100 [V], AC 200 [V], etc.) 16 from the outside and a battery serving as a power supply source of a system different from the commercial AC power source 16. The standby power supply 53 is built in. Therefore, even if the harm prevention interlocking repeater 5 cannot receive the supply of the commercial AC power supply 16 in an emergency, the automatic closing device 3 and the cable are connected by the standby power supply 53 or the standby power supply built in the disaster prevention interlocking controller 92. The type obstacle sensing device 17 can be operated. That is, in the event of an emergency, a DC 24V signal is output from the harm prevention interlocking repeater 5 to the automatic closing device 3 and the wired obstacle sensing device 17. Further, power may be supplied to the wired obstacle sensing device 17 using a timer or the like before power is supplied to the harm prevention interlocking relay 5.

  FIG. 10 is a diagram showing a schematic configuration of a harm prevention interlocking repeater employed in the fire shutter device of FIG. As shown in FIG. 10, the harm prevention interlocking repeater 5 includes a power supply circuit 51, a charging device 52, a standby power supply (storage battery) 53, a power supply switching device 54, and control circuits 55a and 55b. The power supply circuit 51 converts the commercial power supply 16 into a DC 24V signal, supplies a DC voltage to the control circuits 55 a and 55 b via the power supply switching device 54, and supplies power to the charging device 52. The charging device 52 charges the standby power supply (storage battery) 53 using the power from the power supply circuit 51. The standby power supply (storage battery) 53 is composed of a lithium ion rechargeable battery or other batteries, and supplies a DC voltage to the control circuits 55 a and 55 b via the power supply switching device 54. The power source switching device 54 selectively switches either one of the power source circuit 51 or the standby power source 53 and connects it to the control circuits 55a and 55b.

  Usually, since the power from the commercial power supply 16 is supplied, the DC voltage from the power supply circuit 51 is supplied to the control circuits 55a and 55b. However, the power supply from the commercial power supply 16 is supplied in an emergency such as the occurrence of a fire. When the operation is stopped, the operation is performed so that the DC voltage from the standby power supply 53 is supplied to the control circuits 55a and 55b. That is, the standby power supply 53 built in the harm prevention interlocking repeater 5 is connected to the control circuits 55a and 55b even when commercial power is not supplied to the fire prevention shutter device 10 due to some trouble or failure in the event of a fire. It can supply power.

  The control circuit 55a outputs an operation signal (DC 24V signal) based on the disaster prevention signal BS input from the sensor 15, and releases the brake 2. The control circuit 55b outputs an operation signal (DC 24V signal) based on the input of the operation signal of the electric manual closing device 7 (emergency shutter closing button 8), and releases the brake 2. The return switches 56a and 56b forcibly stop the supply of power to the automatic closing device 3.

  As described above, since the control circuit 55a can be supplied with power from a commercial power supply or a standby power supply, an operation signal (DC 24V signal) is generated based on the disaster prevention signal BS input from the sensor 15 to the control circuit 55a. By outputting and releasing the brake 2, the shutter curtain 4 having a fire-proof structure in the winding state is lowered by its own weight, and the opening is automatically closed. At this time, even if there is a problem in the disaster prevention signal path or a problem occurs in the control circuit 55a, the electric manual closing device 7 (emergency shutter closing button 8) is operated, Since the operation signal (DC 24V signal) is output from the control circuit 55b which is another circuit configuration, the shutter curtain 4 can be lowered urgently by manual operation. In addition to the one using the electric manual closing device 7, there is one configured to release the brake and lower the shutter curtain only by mechanical operation without using electricity.

  First, the sensor 15 detects a fire. Then, a fire signal is input from the sensor 15 to the disaster prevention interlocking controller 92. The disaster prevention interlocking controller 92 outputs a disaster prevention signal BS to the harm prevention interlocking repeater 5. The disaster prevention signal BS is often a single signal of about 10 seconds. Since a continuous operation signal (DC 24V signal) is output to the automatic closing device 3 from the control circuit 55a of the harmless interlocking repeater 5, the fire curtain shutter curtain 4 in the wound state is lowered by its own weight. And automatically closes the opening.

  On the other hand, when the electric manual closing device 7 (emergency shutter closing button 8) is operated and a no-voltage A contact ON signal is output to the control circuit 55b of the harm prevention interlock relay 5, the hazard prevention interlock relay is performed. The operation signal (DC 24V signal) is continuously output from the control circuit 55b of the device 5 to the automatic closing device 3, and the fire curtain shutter curtain 4 in the wound state descends by its own weight and automatically closes the opening. Will come to do. At this time, when the electric manual closing device 7 (emergency shutter closing button 8) is operated by receiving power from the standby power supply 53, the remaining electrical capacity of the standby power supply 53 is low or disappears. If the manual closing device 7 (emergency shutter closing button 8) is operated, the shutter curtain 4 cannot be lowered by its own weight. A remaining amount display means is provided so that the remaining amount can be displayed and the remaining amount can be easily confirmed. In this embodiment, since the LED is provided and the light emission state of the indicator lamp is controlled in various ways, the code disconnection state may be recognized from the light emission state.

  When a fire signal is generated from the sensor 15 or when the manual closing device 7 (emergency shutter closing button 8) is operated, the shutter curtain 4 is in the closing operation, that is, the shutter curtain 4 is being lowered. When the sensing device senses an obstacle, a no-voltage A contact ON signal is input to the automatic closing device 3 via the seat plate switch 9 and the wired obstacle sensing device 17, so the automatic closing device 3 automatically The brake is applied and the descent of the shutter curtain 4 is stopped. When the obstacle is removed, a no-voltage A-contact OFF signal is input to the automatic closing device 3 through the seat switch 9 and the wired obstacle sensing device 17 so that the automatic closing device operates again. When the brake is released, the shutter curtain 4 starts to descend by its own weight, and when the opening is fully closed by the shutter curtain 4, the self-weight drop is stopped. At this time, the operation and release of the brake may be performed in response to the supply of power from the standby power supply 53. In addition, by providing a timer, etc., it may be provided for a predetermined time from when the obstacle is removed and the seat switch is turned off until the A contact point OFF signal is input to the automatic closing device, or automatically closed. After the A contact point OFF signal is input to the device, the automatic closing device is provided for a predetermined time until the automatic closing device is activated again. After the obstacle is removed, the automatic closing device is activated again and the brake is released. A predetermined time difference may be provided until the shutter curtain starts to descend due to its own weight.

  In this embodiment, the disaster prevention signal BS and the manual closing device 7 (with the standby power supply 53 built in the harm prevention interlocking relay 5 are provided even if the commercial power supply 16 is not supplied to the fire prevention shutter device 10 in the event of a fire. The brake 2 can be released based on the operation signal of the emergency shutter closing button 8), and the fire curtain shutter curtain 4 in the wound state can be lowered by its own weight to automatically close the opening. . However, this standby power source is composed of a lithium ion rechargeable battery, other batteries, and the like, and has a long service life. Therefore, in this embodiment, the remaining capacity indicator lamp 14 of the electric capacity of the standby power supply 53 is provided in or near the manual closing device 7 (emergency shutter closing button 8). This is because the vicinity of the manual closing device 7 (emergency shutter closing button 8) may be inspected at the time of inspection or the like, so that the remaining amount can be easily confirmed at that time. An LED or the like for displaying the code disconnection state may also be provided in the vicinity of the remaining amount indicator lamp 14.

  FIG. 11 is a flowchart showing an example of the operation of the disaster prevention shutter device of FIG. First, in step S111, it is determined whether or not the sensor signal from the sensor 15 has been received, or whether or not the manual closing device 7 (emergency shutter closing button 8) has been pressed (turned on). If it has been pressed or turned on (yes), the process proceeds to the next step S112, and if it has not been received or has not been pressed (no), the determination in step S111 is made until the signal is received or until it is pressed. Repeat the process.

  In step S112, since the sensor signal is received or the manual closing device 7 (emergency shutter closing button 8) is pressed (ON), the automatic closing device 3 releases the brake. Thereby, in step S113, the shutter curtain 4 starts to descend by its own weight by releasing the brake.

  In step S114, it is determined whether or not any obstacle has contacted the seat plate at the lower end of the shutter curtain 4 and is detected by the seat plate switch (micro switch) 9 incorporated in the seat plate. If (yes), the process proceeds to step S116. If not detected (no), the process proceeds to step S115.

  In step S115, the descent operation of the shutter curtain 4 is continued, and the process returns to step S114. Note that when the shutter curtain 4 descends and comes into contact with the floor surface or the like and becomes fully closed, further closing cannot be performed. In this case, the processing is stopped. On the other hand, when an obstacle detection signal is output from the seat switch (microswitch) 9 and it is determined yes in step S114, the process proceeds to step S115.

  The determination of “yes” in step S114 means that the seat plate has come into contact with some obstacle during the lowering operation of the shutter curtain 4. Therefore, in step S116, the lowering of the shutter curtain 4 is stopped. The stop here is to apply braking, and the stop state (avoidance operation) is maintained until the brake is released in step S112. In addition, after stopping the descent | fall of the shutter curtain 4, you may perform the avoidance operation | movement which raises the shutter curtain 4 only for a fixed time or distance.

  In step S117, the determination in step S117 is repeated until no obstacle detection signal is continuously sensed from the seat board switch (microswitch) 9 built in the seat board. Return to, release the brakes, and resume weight drop. In this embodiment, as long as the obstacle detection signal is continuously sensed, a flow in which this step S117 cannot be exited is shown.

  In the above-described embodiment, when the obstacle detection signal is no longer sensed, the process returns to step S112. However, in the usage mode in which the descent is prioritized, the predetermined state is maintained even in the sensed state. The process may return to step S112 as time elapses, and the descent may be resumed. In some cases, the descent may be lowered by a predetermined distance or may be lowered by a predetermined time.

  FIG. 12 is a diagram showing a modified example of the fire shutter device according to the present invention, and FIG. 13 is a diagram showing a schematic configuration of a modified example of the harm prevention interlock repeater employed in the fire shutter device of FIG. is there. 9 and 10 includes a control circuit 55a that operates in response to an input of a disaster prevention signal BS, and a manual closing device 7 (emergency shutter closing button 8) in a hazard prevention interlocking relay 5. A control circuit 55b that operates in response to an input of an operation signal is provided independently. In this case, if there is a problem in the signal path related to the control opening 55b, or if a problem occurs in the control circuit 55b, the control circuit 55b does not operate even if the emergency shutter closing button (manual closing device) 8 is operated. A condition can occur.

  Therefore, in the modified example of FIGS. 12 and 13, two series of control circuits 551 and 552 having the same configuration are provided, and the disaster prevention signal BS and the manual closing device 7 (emergency use) are provided in the respective control circuits 551 and 552 in different systems. An operation signal for the shutter close button 8) is input. As a result, if there is a problem in the signal path related to the control open circuit 551 or a problem occurs in the control circuit 551, another control circuit 552 sends the disaster prevention signal BS and the manual closing device 7 (emergency shutter closing button 8). It can operate in response to an input of an operation signal. On the other hand, if there is a problem in the signal path related to the control opening 552 or a problem occurs in the control circuit 552, another control circuit 551 sends the disaster prevention signal BS and the manual closing device 7 (emergency shutter closing button 8). It can operate in response to an input of an operation signal. As a result, the fire shutter can be manually closed even when a failure occurs in the electrical circuit of the fire shutter device equipped with the electric manual closing device.

  FIG. 14 is a view showing a further modification of the fire shutter device according to the present invention. In the above-described embodiment, the case where there is one spare power supply has been described. However, as with the control circuits 551 and 552, two independent spare power supplies 531 and 532 are provided, and each supplies power to the control circuits 551 and 552. You may do it. In this case, the two standby power sources 531 and 532 may employ different power source systems (power sources such as dry batteries and power sources such as rechargeable lithium ion rechargeable batteries and other batteries) that are different from each other. Good. The power of the standby power supplies 531 and 532 is also supplied to the switch 1, the remaining amount indicator lamp 14, the battery test indicator lamp 83, the cord disconnection state indicator lamp, and the like. In the figure, the remaining amount indicator lamp 14 may display the total remaining amount of the two standby power supplies, or may display the remaining amounts of the two standby power sources 531 and 532 individually. In addition, when the standby power sources 531 and 532 are replaced, they may be replaced alternately at about half the life of the standby power source. That is, when the lifespan of the standby power sources 531 and 532 is 2 years, by replacing only the standby power source 531 in the first year and only the standby power source 532 in the next year. The same effect as that of exchanging a standby power supply with a lifetime of 2 years every year can be obtained.

  FIG. 15 is a view showing still another modified example of the fire shutter device according to the present invention and corresponding to FIG. In the embodiment of FIG. 6, the standby power source is stored in the vicinity of the harm prevention interlocking relay 5, but in this modification, the standby power source 53 is made of a metal that constitutes the electric manual closing device 7. It is installed in the housing 71 of the above. Thus, by providing the standby power supply 53 in the metal casing 71 constituting the electric manual closing device 7, the replacement of the standby power supply can be easily performed. As shown in FIG. 14, when two standby power supplies 531 and 532 are provided, either one or both may be stored in the casing 71. Further, the standby power source stored in the casing 71 and the standby power source stored in the vicinity of the harm prevention interlocking repeater 5 are different from each other in the power source system (a type of power source that can be used up like a dry battery or a rechargeable lithium ion rechargeable battery). Or other battery power source). Further, two power supply means are provided in the housing 71 of the electric manual closing device 7 or in the vicinity thereof, and the two power supply means supply power to the automatic closing device 3 and the wired obstacle sensing device 17 in different systems. You may make it supply. In FIG. 15, only the remaining amount indicator lamp 14 is provided, the battery test indicator lamp 83 and the cord disconnection state indicator lamp are omitted, and the remaining amount indicator lamp 14 has functions of the battery test indicator lamp 83 and the cord disconnection state indicator lamp. The case where it is used together is shown. In this case, even when the lid 72 is closed, the lighting state of the remaining amount indicator lamp 14 can be confirmed from the outside through the transparent panel 74. In addition, in FIG. 15, the connection relationship regarding the output of the operation signal output from the harm prevention interlocking repeater is not shown.

  FIG. 16 is a diagram showing an example of an automatic battery check process executed by the harm prevention interlocking relay device of FIG. In the above-described embodiment, a case where the battery state (capacity) of the standby power source built in the harm prevention interlocking repeater 5 is manually checked by operating the battery test button 82 or the battery test button 6b will be described. However, in FIG. 16, the harm prevention interlocking repeater 5 operates to automatically (periodically) check the battery state (capacity) of the standby power supply.

  First, in step S161, it is determined whether or not it is a check timing. If the check timing (yes), the process proceeds to the next step S162, and if not (no), the process jumps to step S166. In this check timing, since the timer count is started from when the primary power is turned on, it is determined whether or not the timer count value has reached a value corresponding to 30 days. The predetermined period is an example, and can be arbitrarily set such as a week or a unit of 5 days.

  In step S162, a battery state check process is performed. In this process, a load current is passed through the battery for 3 seconds, and the battery voltage value at that time is measured. In step S163, it is determined whether the battery state check processing result, that is, whether the voltage value when the load current is passed is 21 [V] or more or less than 21 [V], and the voltage value is less than 21 [V] (no ), The process proceeds to the next step, and if it is not 21 [V] or more (yes), the process jumps to step S166.

  In step S164, as a result of the determination in step S163, it is determined that the voltage value is in an abnormal state of less than 21 [V]. Therefore, an abnormal process corresponding to the abnormal state is executed. For example, the battery test indicator lamp 68, the electrical test indicator lamp (LED) 83, etc. are blinked, notified to the user or the like with a buzzer, or the power supply abnormality signal 6f is output to the outside.

  In step S165, it is determined whether or not an abnormality release switch for returning from the abnormality process has been operated. If the abnormality release switch has been operated (yes), the process proceeds to the next step S166, and if not (no) Repeats the abnormality process of step S164. That is, if it is determined that the battery is abnormal by the processing in this step, the abnormal state of the battery is continuously notified until the battery is replaced.

  In step S166, it is determined whether or not it is time to replace the battery. If it is time to replace (yes), the process proceeds to the next step S167, and if not (no), the process returns. In this case, the timer is counted from the time when the primary power is turned on, and it is determined whether or not the timer count value has reached a value corresponding to about five years. This predetermined period is an example and can be set arbitrarily. In this embodiment, the battery replacement time is about 5 years from the start of energization, but there may be other cases depending on the performance of the battery.

  In step S167, as a result of the determination in step S166, it is determined that it is time to replace the battery. Therefore, a replacement time display process similar to that in step S164 is executed. For example, the battery test indicator lamp 68, the electrical test indicator lamp (LED) 83, etc. are blinked, notified to the user or the like with a buzzer, or the power supply abnormality signal 6f is output to the outside.

  In step S168, as in step S165, it is determined whether or not the abnormality release switch for returning from the replacement time display process has been operated. If the abnormality release switch has been operated (yes), the process returns. In the case of (no), the replacement time display process in step S167 is repeatedly executed. That is, if it is determined that the battery replacement time is determined by the processing in this step, the battery replacement time is continuously notified until the battery is replaced. In place of the abnormality release switch, a switch that is turned on and off in conjunction with the removal and installation of the battery is provided, and the battery has been replaced by the change of ON → OFF and / or OFF → ON of this switch. You may make it recognizable.

  In the above-described embodiment, the case where the remaining amount indicator lamp, the cord disconnection status indicator lamp, and the like are provided separately from the emergency shutter closing button 8 is described. However, the emergency shutter closing button 8 itself is configured by an LED, The emergency shutter closing button 8 may be blinked or lit to display that the electric capacity has decreased or that the cord has been disconnected. In the above-described embodiment, the case where the automatic closing device 3 receives power supply from the control circuits 55a and 55b or the control circuits 551 and 552 via different electric systems has been described. You may make it supply via the electrical system of.

  Further, in the above-described embodiment, the fire shutter device that is closed while the shutter curtain that is the opening and closing member is lowered has been described as an example. However, the opening and closing member is extended by the horizontal pulling method or raised. It can be applied in the same manner even if it is drawn out by a method or drawn out by a horizontal method. In addition, although there are some that are not suitable for fire, an appropriate device may be selected as the open / close body according to the type of disaster prevention, for example, a shutter device, a blind device, a roll screen device, a banner device, or the like. When the opening / closing body device is a shutter device, the opening / closing member, which is the opening / closing body means, is a shutter curtain. Pipe curtains made from one piece, panel curtains made from one or more connected panel materials, net curtains made from net materials, sheet curtains made from synthetic resin or cloth fiber sheet materials, or composite members thereof This is due to the composite curtain. The material of the opening / closing member that is the opening / closing member means may be any material as long as it is suitable for the purpose of use. Specifically, it can be made of metal, wood, plastic, cloth, or a composite of these. In the case of an opening / closing body device installed for the purpose of fire prevention, the material of at least the opening / closing member which is the opening / closing body means preferably has fire resistance.

In the above-described embodiment, an example in which an obstacle is detected by abutting against the obstacle, such as a seat plate switch, has been described as an example, but other obstacles can be detected by a tape switch or non-contact. It may be a thing. For example, as an object that detects an obstacle without contact, an infrared light emitting element and a light receiving element are provided on both sides of the opening / closing member, and the obstacle is detected when the infrared light is blocked. There is. The obstacle detection means detects an obstacle present in the opening including the periphery of the opening.
In the above-described embodiment, the manual closing device 7 (emergency shutter closing button 8), which is an electric manual closing device, has been described as being operated by receiving an output from the standby power supply 53. 7 (emergency shutter closing button 8) may be provided with a dedicated spare power supply separately from the spare power supply 53, and in this case, the remaining power may be displayed.
The power for causing each LED to emit light may be supplied from a commercial power source or from a standby power source.
The rechargeable power source may be replaced with a type of power source that can be used up like a dry battery. In this case, charging is not performed, and thus the charging device is disabled or unnecessary. In this case, power supply from a commercial power supply is not necessary if it is not used except for emergency and maintenance inspection.
Equipment that needs to be supplied with power in the event of a commercial power outage may be supplied with power from the harm prevention interlocking relay 5 using a DC 24V signal, etc. When there is a supply, the control mode may be switched to an emergency mode.
