Description

  The present invention relates to a shielding member such as a sheet-like, slat-like, or panel-like fire curtain for partitioning an entrance of a building such as a building or a factory or an opening such as a large room, a passage, a hall space, or a structure such as an underground shopping center. The present invention relates to an opening / closing body device including a fire door, and more particularly to an opening / closing body device in which a shielding member opens and closes using a part of a side end portion of the fire door as a guide rail.

  In general, in the construction of large buildings, etc., in passages and hall spaces inside structures, in the form of sheets and slats that automatically close as soon as a fire occurs to prevent the spread of fire and the spread of smoke in the event of a fire Or, using a shielding member such as a panel-shaped fire curtain, there is provided an opening / closing body device that operates to form a space three-dimensionally enclosed with pillars, walls, floors, etc., that is, a fire prevention compartment or a smoke prevention compartment. ing. In addition, there is a structure in which the opening is closed by using a fire door or the like as a part of the shielding member. Some of these shutter devices are extended to partition an opening for fire prevention, smoke prevention, waterproofing, windproofing, crime prevention, etc. when a disaster other than a fire occurs or when a store is closed.

Recently, as shown in FIG. 1, the guide rail 22 is provided at the side end portion of the fire door 12 adjacent to the guide rail 21 provided at one end portion of the opening portion without providing guide rails at both end portions of the opening portion. An opening / closing body device is proposed that is configured to perform the closing operation of the shutter curtain 4 along the guide rail 21 and the side end guide rail 22 of the fire door 12. As an opening / closing body device in which the fire door 12 has the function of the guide rail 22 as described above, for example, there is a device as described in Patent Document 1.
Utility model registration number 3043893

The opening / closing body device in which the guide rail of the shutter curtain as described above is formed on the side end portion of the door is formed with a locking portion at a door contact portion provided on the floor or ceiling, and locked to this locking portion. Tools are provided on the fire door side. A movable switch for closing the shutter curtain in conjunction with the closing operation of the fire door is installed at the door stop. Accordingly, the fire door is closed first and comes into contact with the door stop, and the shutter curtain starts the closing operation when the movable switch is pushed by the locking tool.
In the open / close body device having such a configuration, the fire door and the shutter curtain are started to be closed by inputting a fire occurrence signal (emergency signal) from a sensor or the like in an emergency such as a fire. Therefore, when the fire occurrence signal from the sensor or the like does not reach the control unit due to disconnection or the like, the fire door and the shutter curtain are not closed, which is not preferable.

  It is an object of the present invention to provide a case where a fire door and a shutter curtain are not closed in response to an emergency signal in a fire door provided with a guide rail and an opening / closing device provided with a shutter curtain that is closed along the guide rail of the fire door. However, it is providing the opening-closing body apparatus comprised so that a fire door and a shutter curtain could be closed.

The first feature of the opening / closing body device of the present invention is that the opening / closing body device rotates and moves from the state of being housed in the housing portion provided on the lateral side of the peripheral portion of the opening, and stops contacting the door stop portion provided on the peripheral portion. Shielding door means for partitioning a part of the opening by the above, closing confirmation means for detecting that the shielding door means has stopped contacting the door stop and outputting a shielding door closing signal, and a peripheral edge of the opening From the state housed in the housing part provided on the upper side, it passes through the entrance / exit part provided on the upper peripheral edge and is formed on the side edge part side of the shielding door means after contact stop at the door stop part. The opening / closing body means for lowering the remaining portion of the opening that is lowered along the guide groove and is not partitioned by the shielding door means, and the shielding door means according to the input of an artificial operation signal. Rotating and moving the shielding door means If after starting the rotational movement entered the shielding door closing signal from the closing confirmation means is to have a self-closing means for lowering the closing body means in response to input of the shield door closing signal.
Shielding door means such as fire doors partition (close) part of openings such as entrances, windows, internal passages and spaces in structures such as buildings, houses, factories, and warehouses. . This fire door is usually housed in a housing provided on the side of the peripheral edge of the opening. When a disaster occurs, it is stopped by rotating and moving from the state of being housed on the side of the peripheral edge and coming into contact with the door stop provided on the upper (ceiling) side or lower (floor) side of the peripheral edge. Divide part of the part. The closing confirmation means detects that the fire door has stopped contacting the door stop and outputs a shielding door closing signal. The shutter curtain, which is an opening / closing body means, has an opening along a guide groove (guide rail) formed at a side end of a fire door adjacent to a guide groove (guide rail) provided at one end of the opening. The remaining portion of the opening which is fed out through the entrance / exit part on the upper edge of the rim and not partitioned by the fire door is partitioned (closed). The opening / closing member means is configured to start the closing operation of the shielding door means and the opening / closing member means by inputting an emergency signal such as a fire occurrence signal. Therefore, when an emergency signal is not input to the automatic closing means as the control unit due to some trouble, the shielding door means and the opening / closing body means are not closed in response to the closing confirmation signal. Therefore, in the present invention, the shielding door means is rotated in response to an input of an artificial operation signal output from a manual closing device (emergency closing means instruction means), and the closing confirmation means is rotated after the shielding door means is rotated. When the shielding door closing signal is input from the door, the opening / closing member means is lowered in response to the input of the shielding door closing signal. Thus, even when an emergency signal is not input to the closing means due to some trouble, the shielding door means and the opening / closing body means are closed by manually operating a manual closing device (emergency closing means indicating means) or the like. There is an effect that can be. Here, after the start of the rotational movement of the fire door, it means that the fire door is after the time when the instruction of the rotational movement is issued even if the fire door does not rotate at all.
According to a second feature of the opening / closing member device of the present invention, in the opening / closing member device according to the first feature, the closing confirmation signal from the closing confirmation means within a predetermined time after the start of the rotational movement of the shielding door means. In response to the input of the shielding door closing signal, the opening / closing member means is lowered and the shielding door closing signal is input from the closing confirmation means within the predetermined time after the start of the rotational movement of the shielding door means. If not, the opening / closing member means is lowered after the predetermined time has elapsed. When a closing door closing signal is input from the closing confirmation means within a predetermined time after the fire door starts rotating, the opening / closing means is lowered in response to the input of the closing door closing signal, and the predetermined time after the fire door starts rotating. When the closing door closing signal is not input from the closing confirmation means within the time, the opening / closing body means is forcibly lowered after a predetermined time has elapsed.

  According to the opening / closing body device of the present invention, the fire door and the shutter curtain are closed according to the emergency signal in the fire door having the guide rail and the shutter curtain closing along the guide rail of the fire door. Even if not, there is an effect that the fire door and the shutter curtain can be manually closed.

  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. 2 is a diagram 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 is housed in a housing part provided above the peripheral edge of the opening by winding the shutter curtain 4 around a winding shaft (not shown). As another example, there is a case in which the shutter curtain is stored in the storage unit without being wound and is opened. This open state is maintained by being mechanically held by the brake 2. Then, in the event of a fire, the automatic closing device 3 is provided with a disaster prevention signal BS and an electric manual closure from the sensor 15 (or an interlocking controller connected to the sensor or a disaster prevention panel) input via the interlocking relay 5. In response to the operation signal of the device 7 (including the emergency shutter closing button), the release of the brake 2 is released, and the shutter curtain 4 is pulled out from the storage portion by natural descent under its own weight, thereby opening the opening. It is closed (partitioned) to form a predetermined fire protection compartment.

  The sensor 15 for outputting the disaster prevention signal BS to the interlocking repeater, the interlocking controller connected to the sensor, the disaster prevention panel, and the like are appropriately selected and provided depending on the installation environment. A plurality of sensors may be provided, but when one or more of the plurality of sensors are detected, the number of disaster prevention signals corresponding to the detection of the plurality of disaster prevention BSs is input to the interlocking repeater. Alternatively, a single disaster prevention signal BS may be input to the interlocking repeater when one or more of a plurality of sensors 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 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. In the normal time when the shutter curtain 4 does not need to be opened and closed, the shutter 1 may be configured only by the brake 2 instead of the switch 1 and the brake 2 which are driving sources as illustrated. When the disaster prevention signal BS is input, the interlocking relay 5 outputs a DC 24V signal that is a voltage signal to the automatic closing device 3. The interlock repeater 5 normally uses a commercial power supply 16 to output a DC 24V signal, but at the time of a power failure or the like, the interlock repeater 5 is powered by power from a standby power supply (battery such as a storage battery) built in the interlock repeater 5 DC 24V signal is output.

  The automatic closing device 3 is a commercial power source 16 supplied via the interlocking relay 5 or a standby power source (storage battery) built in the interlocking relay 5 like a known automatic closing device used for a conventional fire shutter or the like. It operates according to the electric power (DC 24V signal) from. Further, the automatic closing device 3 operates using the power of the 24V signal supplied from the interlocking relay 5 having a built-in shutter power supply, so that even if there is no supply of commercial power to the fire prevention shutter device 10 in the event of a fire. The brake 2 is released based on the disaster prevention signal BS input from the sensor 15 or the like, and the shutter curtain 4 having a fire prevention structure in the wound state is lowered by its own weight, so that the opening can be automatically closed. ing.

  The electric manual closing device 7 is mainly used for operating a shutter for opening and closing the shutter electrically operated and manually inputting a start signal for causing the interlock repeater to perform the same operation as when the disaster prevention signal BS is input. It is. The electric manual closing device 7 includes an input switch (push button switch) for normal operation corresponding to an instruction to open / close the shutter curtain to the switch 1, an operation button that is an emergency shutter closing button, a recovery button, It includes a battery test button and the like, and further includes various display means for displaying the battery test result, displaying the status of the standby power supply, and displaying the code disconnection status. Although the electric manual closing device 7 is illustrated above the fire door 12 in FIG. 2, it is actually installed at a position where a person such as a housing near the fire door 12 can operate. In particular, the operation button of the electric manual closing device 7 is covered with a resin transparent panel (push-break cap), and the emergency shutter closing button is configured to be operated by pushing the resin transparent panel in an emergency. (Actuation button).

  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 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.

  In a general configuration of a fire shutter device provided with a fire door in addition to the shutter curtain, on both sides of the shutter curtain 4, guide rails provided at the opening side end and an opening between the shutter curtain and the fire door There is a guide rail called a middle pillar provided in the section. In this embodiment, the guide rail 21 is provided on one side (left side in the drawing) of the shutter curtain 4, but there is no center pillar, and a concave groove is provided in a part of the side end of the fire door 12. It is used as the guide rail 22. Therefore, in the case of the opening / closing body device according to this embodiment, the guide rails do not exist on both sides of the shutter curtain 4 unless the fire door 12 is rotated and closed (partitioned).

  Therefore, in this embodiment, the closing confirmation switch 24 for closing the shutter curtain 4 in conjunction with the closing operation of the fire door 12 which is a sleeve door provided as a shielding door means is a door stop portion or an opening portion. The shutter curtain 4 is configured to start the closing operation when the fire door 12 is closed first and the switch 24 for closing confirmation is operated. The fire door 12 is always open, and is usually stored in a door pocket or the like provided on a column or wall on the side of the opening. In this normally open type fire door 12, an evacuation passage is secured by a diving door 121 provided separately in the closed fire door. Since the automatic closing operation of the fire door is known, it will be briefly described here. The fire door is normally restrained in an open state by a fire door automatic closing device (not shown), but when the restraint is released by the fire door automatic closing device, its own weight (using a so-called gravity hinge, etc.) or spring force ( It is configured to be closed by an urging force such as using a closer. The automatic closing device for fire doors is electrically connected to an external device power supply terminal (24 volt output terminal: terminal 24-0) provided in the interlock repeater, and the hazard prevention interlock repeater inputs an activation signal. Accordingly, when a voltage of 24 [V] is output as a voltage signal from the external device power supply terminal to the automatic closing device for the fire door, the fire door is unconstrained using the electric power and the fire door is closed. In addition, when a fire door manual closing device (emergency closing instruction means) is connected to the fire door automatic closing device, the fire door automatic closing device is also fire-proof by operating the fire door manual closing device. You can also release the door restraint and close the fire door. The automatic closing device for a fire door may be one that electrically outputs a closing instruction signal to the automatic closing device for a fire door, or one that mechanically acts to activate the automatic closing device for a fire door.

  FIG. 3 is a diagram illustrating an example in which a fire door, which is a sleeve door, and a shutter curtain operate in conjunction with each other. First, in step 31, the interlocking repeater 5 is in a standby state. In step 32, the interlock repeater 5 determines whether or not the disaster prevention signal BS or the activation signal has been input. If it is input (yes), the process proceeds to the next step 33, and if it is not input (no). Returning to step 31, the processes of steps 31 and 32 are repeatedly executed until an activation signal is input. Here, as a type of the start signal, when the disaster prevention signal BS, the signal from the electric manual closing device start switch, the signal from the start switch for inspection provided in the interlock repeater 5, the start signal is transmitted from a remote place Or a signal from an external activation switch that may be connected when transmitting simultaneously to a plurality of disaster prevention shutter devices. In step 32, instead of determining that the activation signal has been input, has the sleeve door state detection means (not shown) detected the start of closing operation of the sleeve door (fire door) that is closed in response to the input of the activation signal? You may make it determine whether. In step 33, a voltage of 24 [V] is output from the external device power supply terminal (24 volt output terminal: terminal 24-0) provided in the interlock repeater 5, the fire door is closed, and the sleeve door interlock standby state. And a 60 second timer is started.

  In step 34, it is determined whether or not a sleeve door closing signal is input from the closing confirmation switch 24 by closing the sleeve door. If the sleeve door closing signal is input (yes), the process proceeds to the next step 35 and is not input (no). If so, go to Step 37. In step 35, since the sleeve door closing signal is input from the closing confirmation switch 24, the counting of the 60 second timer is stopped and the start delay timer (delay time of about 3 seconds) is started. The activation delay timer is not for immediately closing the shutter curtain when a sleeve door closing signal is input from the closing confirmation switch 24, but for closing the shutter curtain with a slight delay. In step 36, it is determined whether or not the activation delay timer started in step 35 has been counted up. If it has been counted up (yes), the process proceeds to step 38. If it has not been counted up (no), the activation delay is counted. The determination process of step 36 is repeatedly executed until the timer counts up.

  In step 37, since it is determined that the sleeve door closing signal is not input from the closing confirmation switch 24, it is determined whether or not the 60-second timer started in step 33 has been counted up (step 37). If yes, the process proceeds to step 38. If not counted up (no), the process returns to step 34, and the processes of steps 34 and 36 are repeated until the count is incremented. In step 38, the process is executed when it is determined in step 36 that the activation delay timer has been counted up, or when it is determined in step 36 that the 60-second timer has been counted up, and the automatic closing device 3 is activated. The shutter curtain automatic closing process is executed. Thus, in the above-described sleeve door interlock operation flow, when the sleeve door closing signal is not input, the 60 second timer is set, and the shutter curtain is automatically closed after 60 seconds. It is like that.

  FIG. 4 is a diagram illustrating another example of a case where a fire door, which is a sleeve door, and a shutter curtain operate in conjunction with each other. First, in step 41, a start signal input confirmation process, which is the same process as in steps 31 and 32 of FIG. 3, is performed. That is, since the automatic closing device 3 is normally in a standby state, it is determined whether or not an activation signal has been input. If it is input (yes), the process proceeds to the next step 42, and if it is not input (no). This determination process is repeatedly executed. In step 41, instead of determining that the activation signal has been input as in step 32, the start of the closing operation of the sleeve door (fire door) that closes in response to the input of the activation signal is detected by the sleeve door state detection (not shown). You may make it determine whether it detected by the means. In step 42, the interlocking repeater 5 is activated. In step 43, the automatic closing device for fire doors on the door side (or the doors on both sides when doors exist on both the left and right sides of the shutter curtain 4) are operated. In step 44, a door closing process is executed (or doors on both sides if there are doors on the left and right sides of the shutter curtain 4).

  In step 45, since the door closing process is started in step 44, the interlock repeater 5 starts an operation delay timer for operating the shutter-side automatic closing device. In step 46, it is determined whether or not the operation delay timer started in the previous step has been counted up. If it has been counted up (yes), the process proceeds to step 47. If it has not been counted up (no), step 46 is performed. Repeat the process. In step 47, it is a process executed when it is determined in step 46 that the operation delay timer has been counted up, and the interlock repeater 5 activates the shutter-side automatic closing device 3. In step 48, an automatic closing process by the automatic closing device 3 is executed. As described above, in the sleeve door interlocking operation flow of FIG. 4, automatic door closing is executed in response to the input of the activation signal, and then forcedly depending on the timer count-up process (regardless of the fire door closing status). ) Is designed to automatically close the shutter curtain.

  FIG. 5 is a diagram showing still another example in the case where the fire door as the sleeve door and the shutter curtain operate in conjunction with each other. First, in step 51, the automatic closing device 3 is in a standby state. In step 52, the automatic closing device 3 determines whether or not an activation signal has been input. If the activation signal has been input (yes), the process proceeds to the next step 53, and if not input (no), the process returns to step 51. Until the activation signal is input, the processes of steps 51 and 52 are repeatedly executed. In step 53, a voltage of 24 [V] is outputted from the external device power supply terminal (24 volt output terminal: terminal 24-0), the fire door is closed, and the sleeve door interlocking standby state is set and a 60 second timer is set. Start.

  In step 54, it is determined whether or not a sleeve door closing signal is input from the closing confirmation switch 24. If it is input (yes), the process proceeds to the next step 55, and if it is not input (no), the process proceeds to step 57. move on. In step 55, since the sleeve door closing signal is input from the closing confirmation switch 24, the count of the 60 second timer is stopped and the start delay timer (delay time of about 3 seconds) is started. The activation delay timer is not for immediately closing the shutter curtain when a sleeve door closing signal is input from the closing confirmation switch 24, but for closing the shutter curtain with a slight delay. In step 56, it is determined whether or not the activation delay timer started in step 55 has been counted up. If it has been counted up (yes), the process proceeds to step 5A, and if it has not been counted up (no), the activation delay is determined. The process of step 56 is repeatedly executed until the timer counts up.

  In step 57, since it is determined that the sleeve door closing signal is not input from the closing confirmation switch 24, the start switch from the electric manual closing device (hand-closing device) 7 after the 60 second timer start (step 55). Is entered (yes), the process proceeds to step 58, and if not entered (no), the process proceeds to step 59. In step 58, since it is determined in step 57 that the start switch from the electric manual closing device 7 has been input, the count-up of the 60-second timer is stopped and the process proceeds to step 5A. In step 59, since it is determined that the sleeve door closing signal is not inputted from the closing confirmation switch 24 and the activation switch from the electric manual closing device 7 is not inputted, the 60 seconds started in step 53 are started. It is determined whether or not the timer has counted up. If the timer has been counted up (yes), the process proceeds to step 5A. If the timer has not been counted up (no), the process returns to step 54. The processes 57 and 59 are repeatedly executed. In step 5A, if it is determined in step 56 that the activation delay timer has been counted up, if it is determined in step 59 that the 60-second timer has been counted up, or the activation switch from the electric manual closing device 7 is input. The automatic closing device 3 is activated to execute the shutter curtain automatic closing process.

  In the above-mentioned sleeve door interlocking operation flow, when the sleeve door closing signal is not inputted, a 60 second timer is set, and the shutter curtain is automatically closed after 60 seconds. When the electric manual closing device 7 is operated before the up, the shutter curtain is forcibly lowered immediately. In this case, the fire protection compartment can be substantially formed by manually closing the sleeve door even after the shutter curtain is lowered. On the contrary, after the shutter curtain descends, there is a possibility that the shutter curtain may be broken by closing the sleeve door. In such a case, a door stop protruding from the lintel is provided only when the shutter curtain is closed. The sleeve door may not collide with the shutter curtain 4.

  In the above-described embodiment, the case where the sleeve door and the shutter curtain operate in conjunction with each other has been described. However, after the sleeve door is manually or electrically closed, the shutter curtain is electrically operated using the electric manual closing device 7. You may make it operate. In this case, when the sleeve door closing signal is not inputted, that is, when the sleeve door is not closed, the input of the open / close switch of the push button of the electric manual closing device 7 is invalidated, and in this state the normal input switch For example, a battery test indicator (LED) of the electric manual closing device 7 is turned on only during the input, and the user cannot operate with the electric manual closing device 7 (sleeves). You may make it display that a door is not closed. In addition, when the sleeve door closing signal is input for 3 seconds in this state, the input of the push button opening / closing switch is validated, and the shutter curtain and / or the sleeve door is electrically opened / closed. Alternatively, an electric operation of the sleeve door may be enabled.

  In this way, when the shutter curtain and / or the sleeve door is electrically operated temporarily, when the sleeve door is opened and the sleeve door closing signal is not input, the electric manual closing device 7 A stop signal may be output for about 1 second to stop the shutter curtain closing operation, and the open / close switch of the electric manual closing device 7 may be disabled. Even when the sleeve door closing signal is not inputted when the electric manual closing device 7 is turned on, a stop signal of the electric manual closing device 7 is similarly output for about 1 second.

  When the sleeve door closing signal is not input, that is, the sleeve door is not closed, the stop switch of the input switch for normal operation of the electric manual closing device 7 is, for example, about 5 times (about 5 times for 10 seconds). When operated, for example, for 2 minutes, the normal operation input switch of the electric manual closing device 7 is operated (limited to the push-off operation that opens and closes only during input) to open and close You may be able to do. The state in which the sleeve door closing signal is not input as described above is referred to as a sleeve door interlocking forced operation state. After 2 minutes, a stop output is output for 1 second, for example, and the input of the open / close switch of the push button of the electric manual closing device 7 is invalidated.

  If the sleeve door closing signal continues to be input for 3 seconds during the sleeve door interlocked operation state, the input of the open / close switch of the normal operation input switch is enabled and the shutter curtain is electrically opened and closed as described above. In other words, it enables electric operation of a normal shutter curtain. In addition, when the sleeve door closing signal is not input and the input of the open / close switch of the normal operation input switch of the electric manual closing device 7 is in an invalid state, the disaster prevention signal is activated from the electric manual closing device. Even if any signal such as a signal from the switch, a signal from the inspection start switch, or a signal from the external start switch is input, the input to the open / close switch of the normal operation input switch of the electric manual closing device 7 is The input of the open / close switch of the normal operation input switch is validated only when the sleeve door closing signal is continuously input for 3 seconds while the invalid state remains.

  The automatic closing device 3 outputs an external notification signal of about 2 seconds when the automatic closing process is started by normal activation through the processing of step 36 or step 56. After the processing of step 59, when the shutter curtain automatic closing process is started due to the 60 second timer counting up (during abnormal closing), the output time of this external notification signal is about 4 seconds longer than usual. Is output to the outside that it is an automatic closing process due to abnormal closing. In addition, here, it was made possible to recognize whether it was normally closed or abnormally closed by changing the output time of the external start signal, but normal close and abnormal close were made by changing the voltage or waveform of the external start signal in various ways. The difference may be output to the outside as a signal that can be recognized.

  In the above-described embodiment, when it is determined in step 34 or step 54 that the sleeve door closing signal is input, the activation delay timer is started, and the recovery button is operated before the shutter curtain is lowered, the sleeve door is operated. You may make it return to an interlocking standby state. Further, regardless of whether or not the sleeve door closing signal is input, when the recovery button is operated before the shutter curtain is lowered, the sleeve door interlock standby state may be restored.

  In the embodiment of FIG. 5 described above, the case where the sleeve door interlocking standby state is performed when the activation signal is input and the sleeve door and the shutter curtain are interlockingly closed is described. By operating, it may be possible to execute the interlocking closing operation of the sleeve door and the shutter curtain as in the case where the activation signal is input.

  The interlocking repeater 5 is preferably located inside or outside the shutter case, at a location closest to the automatic closing device, which facilitates battery maintenance and the like. Moreover, it is preferable that an automatic closing device is arrange | positioned near a sleeve door and an opening / closing machine.

  In the embodiment of FIG. 4 described above, when the door side exists on both sides of the opening, the doors on both sides are automatically closed, and then the shutter curtain is automatically closed according to the timer count-up process. In the case of the sleeve door closing signal input presence / absence determination processing at step 34 in FIG. 3 and step 54 in FIG. 5, when there are sleeve doors on both sides of the opening, both sleeve door closing signals are If it is input, it is determined that the sleeve door closing signal is input. A case where a sleeve door closing signal is input from either one of the sleeve doors may be determined as having a sleeve door closing signal input.

  In the above-described embodiment, the case where the sleeve door closing confirmation switch 24 is configured by one limit switch has been described. However, two or more limit switches may be connected to a plurality of sleeves according to the sleeve door closing. When it is provided so that a door closing signal is output, it may be determined that a sleeve door closing signal is input when a sleeve door closing signal is output from any of the limit switches. In this case, when a sleeve door closing signal is output from all of the plurality of limit switches, a case where a sleeve door closing signal is output from a specific limit switch among the plurality of limit switches is referred to as a sleeve door closing signal being input. You may make it determine.

  FIG. 6 is a view of the state of the area where the sleeve door is movable as seen from the upper part of the opening. If a person stops in the area where the sleeve door is movable or if an obstacle is placed, the sleeve door will be obstructed. As shown in Fig. 6, the tape ( It is desirable to stick a yellow and black striped tape) on the floor or to display an indication to call attention. This improves the reliability of the fire protection equipment. In addition, if there is a person in the closed part of the sleeve door, the sleeve door may not close or may come into contact with the sleeve door. The fire door is now closed. The sleeve door may be closed when the surrounding people are alerted with a voice announcement or light. As a result, it is possible to prompt the person who is in the movable area of the sleeve door to move out quickly. In this case, after inputting the sleeve door closing signal, “The shutter will close now. be careful. Is performed about 1 to 3 times, and the shutter curtain descending process is started after the announcement is completed. That is, in the process of step 35 or step 55, the start delay timer is started and this voice announcement is performed. If the sound announcement duration is set to the time of the activation delay timer, the sleeve door will just start the closing process after the voice announcement is completed.

  FIG. 7 is a diagram illustrating an example of a case where a fire door, which is a sleeve door, and a shutter curtain operate in conjunction with each other and make a voice announcement before the fire door is closed. First, in step 71, the automatic closing device 3 is in a standby state. In step 72, the automatic closing device 3 determines whether or not an activation signal has been input. If the activation signal has been input (yes), the process proceeds to the next step 73. If not (no), the process returns to step 71. Until the activation signal is input, the processes of steps 71 and 72 are repeatedly executed. In step 73, since the start signal is input, “The fire door will close now. be careful. Start a voice announcement like Close the sleeve door after alerting the surrounding people by voice announcement. As a result, it is possible to prompt the person who is in the movable area of the sleeve door to move out quickly. In step 74, it is determined whether or not the voice announcement started in step 73 has been performed a predetermined number of times (for example, three times in this embodiment), and if it has been performed a predetermined number of times (yes), the process proceeds to step 75. If not (no), the determination process of step 74 is repeatedly executed until a voice announcement is made a predetermined number of times. In addition, it may replace with audio | voice announcement and you may make it display so that visual recognition is possible using light, a display means, etc., and you may make it display visually recognizable with audio | voice announcement.

  In step 75, a voltage of 24 [V] is output from the external device power supply terminal (24 volt output terminal: terminal 24-0) provided in the interlock repeater 5, and the sleeve door interlock standby state is set and 60 seconds. Start the timer. In step 76, it is determined whether or not a sleeve door closing signal is input from the closing confirmation switch 24. If it is input (yes), the process proceeds to the next step 77, and if it is not input (no), the process proceeds to step 79. move on. In step 77, since the sleeve door closing signal is inputted from the closing confirmation switch 24, the counting of the 60 second timer is stopped and the start delay timer (delay time of about 6 to 10 seconds) is started. The start delay timer does not immediately close the shutter curtain when the sleeve door closing signal is input from the closing confirmation switch 24, but “the shutter is now closed. be careful. Start a voice announcement like ”and close the shutter curtains when alerting the people around you. This prompts the person on the movement path of the shutter curtain to move out quickly. In step 78, it is determined whether or not the activation delay timer started in step 77 has been counted up. If it has been counted up (yes), the process proceeds to step 7C, and if it has not been counted up (no), the activation delay is counted. Step 78 is repeated until the timer counts up. Also in this case, it may be possible to display in a visually recognizable manner using light or display means instead of the audio announcement, or a display that is visible together with the audio announcement may be performed.

  In step 79, since it is determined that the sleeve door closing signal is not inputted from the closing confirmation switch 24, the start switch from the electric manual closing device (hand-closing device) 7 after the 60 second timer start (step 75). Is input, if yes (Yes), the process proceeds to Step 7A, and if not input (No), the process proceeds to Step 7B. In step 7A, since it is determined in step 79 that the start switch from the electric manual closing device 7 has been input, the count-up of the 60-second timer is stopped and the process proceeds to step 7C. In Step 7B, since it is determined that the sleeve door closing signal is not input from the closing confirmation switch 24 and the activation switch from the electric manual closing device 7 is not input, the 60 seconds started in Step 75 is started. It is determined whether or not the timer has counted up. If the timer has been counted up (yes), the process proceeds to step 7C. If the timer has not been counted up (no), the process returns to step 76. The processing of 79 and 7B is repeated. In step 7C, if it is determined in step 78 that the activation delay timer has been counted up, if it is determined in step 7B that the 60-second timer has been counted up, or the activation switch from the electric manual closing device 7 is input. The automatic closing device 3 is activated to execute the shutter curtain automatic closing process. As described above, in the above-described sleeve door interlocking operation flow, the voice announcement and the visible display are performed before the sleeve door is closed and the shutter curtain is closed.

  In the above-described embodiment, the processing when the activation signal is input and the sleeve door closing signal is input has been described. However, the interlock relay does not input the activation signal, but the sleeve door closing signal is input. May be outputted, an erroneous closing signal indicating that the sleeve door is accidentally closed may be output. A manual closing device for a fire door that operates a fire door automatic closing device (not shown) is provided, and when this fire door manual closing device is operated to close the fire door and there is a shielding door closing signal, it is interlocked The repeater may output a 24V signal to the self-closing device immediately or after a predetermined time even if no activation signal is input, and close the shutter curtain. Further, the interlock repeater detects that this manual operation of the fire door manual closing device has operated the fire door emergency close instruction, and thereafter, the same control as when an activation signal is input to the interlock relay (step 33 ( Alternatively, the control after step 42, 53, 73) may be performed. In this case, an artificial emergency closing operation can be performed even if the electric manual closing device 7 that outputs an activation signal to the interlocking repeater is omitted.

  Conventionally, interlocking repeaters have different pipe take-out positions at each site, so pipe outlets are located above and below the interlock repeater so that pipes can be connected from above or below depending on this take-out position. It is provided. When the pipe outlets are provided above and below the interlock repeater in this way, the interlock repeater itself becomes large, and there is a problem that the installation location is restricted and further the cost is increased. Therefore, in this embodiment, the piping outlet and the wiring space of the interlocking repeater are provided only on one side, the interlocking relay itself is downsized, the installation place is not restricted, and the cost is reduced.
