(A) Embodiment Hereinafter, an embodiment of an opening / closing body control device of the present invention will be described with reference to the drawings.

  This embodiment is a case where the opening / closing body control device of the present invention is applied to a disaster prevention shutter system typified by a fire prevention shutter or a smoke prevention shutter provided in a certain disaster prevention section.

(A-1) Configuration of Embodiment FIG. 1 is a diagram illustrating a schematic overall configuration of a disaster prevention shutter drive control system that controls the operation of the disaster prevention shutter according to the present embodiment.

  As shown in FIG. 1, the disaster prevention shutter drive control system 10 of this embodiment is provided with shutter guide rails 8a and 8b so that a certain disaster prevention section can be formed, and is guided by the shutter guide rails 8a and 8b to lower its own weight. A shutter curtain 6 that can be used, a control means 1 that receives a disaster prevention signal from a control panel (not shown) and controls the operation of the disaster prevention shutter drive control system 10, and a brake mechanism 3 that brakes the shutter curtain 6 under the control of the control means 1. And an automatic closing device 4 at least.

  In the disaster prevention shutter drive control system 10 of the present embodiment, the shutter curtain 6 is wound up in a normal time when no disaster occurs, and the wound shutter curtain 6 is stored, and the opening is in an open state. ing. At this time, the brake mechanism 3 brakes the shutter curtain 6 so that the shutter curtain 6 does not drop by its own weight. An operation switch (not shown) may be connected so that the opening / closing operation of the shutter curtain 6 can be operated from the operation switch.

  The shutter curtain 6 is provided with an infrared light transmitting unit 5a and an infrared light receiving unit 5b whose optical axes coincide with each other, and obstacle sensing devices 7a and 7b. Power can be supplied to the infrared light transmitting unit 5a and the infrared light receiving unit 5b, and the sensing switch 7a of the obstacle sensing device by a wired power source or a battery power source.

  The infrared light transmitting unit 5a transmits infrared rays, and the infrared light receiving unit 5b receives the infrared light transmitted by the infrared light transmitting unit 5a and receives an electrical signal obtained by photoelectric conversion (in this embodiment, infrared light receiving). A signal) is given to the automatic closing device 4.

  Thereby, it is possible to notify the automatic closing device 4 that the infrared light receiving unit 5b is receiving infrared light. In addition, if the infrared light receiver 5b can notify the automatic closing device 4 whether or not infrared rays are received, a notification signal notifying that infrared rays are not received when infrared rays are not received. The automatic closing device 4 may be provided.

  In the present embodiment, when the infrared light receiving unit 5b does not receive infrared light, for example, when the shutter curtain 6 is lowered by its own weight, the infrared light transmitted from the infrared light transmitting unit 5a is blocked by smoke generated by a disaster. The case where the light-receiving part 5b cannot receive infrared rays etc. is assumed.

  Note that the communication method in which the infrared light receiving unit 5b notifies the automatic closing device 4 of the infrared light reception signal may be, for example, a wired line or a wireless connection. In the case of wireless connection, the infrared light receiving unit 5b and the automatic closing device 4 are required to have a wireless communication function.

  Moreover, as for the positional relationship between the infrared light transmitting unit 5a and the infrared light receiving unit 5b, it is desirable that the infrared light receiving unit 5b is located on the optical axis of the infrared light transmitted by the infrared light transmitting unit 5a. Therefore, the infrared light transmitting unit 5a and the infrared light receiving unit 5b should be positioned on the optical axis even when the shutter curtain 6 is being wound up during normal times or while the shutter curtain 6 is falling under its own weight during a disaster. Is desirable.

  Next, the installation positions of the infrared light transmitting unit 5a and the infrared light receiving unit 5b in the shutter curtain 6 will be described.

  The installation positions of the infrared light transmitting unit 5a and the infrared light receiving unit 5b in the shutter curtain 6 are not particularly limited, but in the present embodiment, one set is provided on each of the front surface and the back surface in the vicinity of the closing side end of the shutter curtain 6. An infrared light transmitting unit 5a and an infrared light receiving unit 5b are provided. That is, two sets of infrared light transmitting unit 5a and infrared light receiving unit 5b are provided for one shutter curtain 6.

  As described above, the reason for providing each pair of the infrared light transmitting part 5a and the infrared light receiving part 5b on both surfaces of the shutter curtain 6 is from any space (section) formed by the lowering of the shutter curtain 6. This is to make it possible to cope with smoke.

  When it is sufficient to cope with smoke from one specific space, a set of infrared light transmitting unit 5a and infrared light receiving unit 5b may be provided only on one surface of the shutter curtain 6 on the specific single surface side. it can.

  FIG. 2 is a diagram illustrating two examples of the installation positions of the infrared light transmitting unit 5 a and the infrared light receiving unit 5 b in the shutter curtain 6. FIG. 2 is a cross-sectional view with respect to the optical axis of infrared rays.

  In the example of FIG. 2A, a pair of infrared light transmitting unit 5a and infrared light receiving unit 5b are provided on both surfaces of the shutter curtain 6 so that the optical axes of the infrared rays of each group are parallel to the shutter curtain 6. Is the case.

  In the example of FIG. 2B, each set of infrared light transmitting unit 5a and infrared light receiving unit 5b is provided on the opposite surface so that the optical axes of the infrared rays of each set intersect each other. The example of FIG. 2B is applicable when the shutter curtain 6 is transparent, for example.

  As shown in the example of FIGS. 2A and 2B, the infrared light transmitting unit 5 a and the infrared light receiving unit 5 b in the shutter curtain 6 maintain the optical axis as the shutter curtain 6 is opened and closed, while maintaining the optical axis. It is installed to move with.

  Returning to FIG. 1, the shutter curtain 6 includes an obstacle sensing device 7 a at the closed end. The obstacle sensing device 7a is provided, for example, at the lower end of the shutter curtain 6 and the like, and a sensing switch 7a that sends a sensing signal when the obstacle is touched, and a detection that detects the sensing signal sent by the sensing switch 7a. Part 7b. The detection unit 7b is fixedly provided on, for example, a lintel so that the detection signal from the detection switch 7a can be received.

  As a method for the detection unit 7b to detect the sensing state of the sensing switch 7a, for example, there is a method for detecting the sensing state by wiring a wire or transmitting wirelessly. The detection unit 7 b detects the sensing state of the sensing switch 7 a and gives an obstacle sensing signal to the automatic closing device 4.

  The control means 1 controls the function of the disaster prevention shutter drive control system 10. The control means 1 controls the automatic closing device 4 so that the brake mechanism 3 applies a brake during normal operation.

  In addition, when a disaster prevention signal is received from a control panel (not shown) at the time of a disaster, the control means 1 gives the disaster prevention signal to the automatic closing device 4 so as to release the brake of the brake mechanism 3.

  The automatic closing device 4 controls the operation of the brake mechanism 3 according to the control of the control means 1. That is, the automatic closing device 4 has a brake release motor 41 that controls the driving of the brake mechanism 3. When a disaster prevention signal is received from the control means 1 at the time of a disaster, the brake release motor 41 is operated based on the disaster prevention signal. The brake of the brake mechanism 3 is released. In normal times, the brake release motor 41 is not operated, and the brake mechanism 3 remains braked.

  In addition, the automatic closing device 4 does not operate the brake release motor 41 while receiving the infrared light receiving signal from the infrared light receiving unit 5b after receiving the disaster prevention signal, and causes the brake mechanism 3 to brake. It is. Thereby, even if a disaster occurs and a disaster prevention signal is given, the shutter curtain 6 is not lowered immediately, so an evacuation route can be secured.

  In addition, a shielding member may be provided so as to shield infrared rays during a period from when the shutter is fully opened to when the distance is lowered for a certain distance so that the distance is lowered immediately after receiving the disaster prevention signal.

  Further, the automatic closing device 4 operates the brake release motor 41 to release the brake of the brake mechanism 3 when the infrared light receiving signal is not given from the infrared light receiving unit 5b after receiving the disaster prevention signal. As a result, when the infrared ray cannot be received, the shutter curtain 6 can be lowered immediately, so that safety against disasters can be ensured.

  The automatic closing device 4 once again activates the brake releasing motor 41 and then again interrupts the operation of the brake releasing motor 41 when receiving the infrared light receiving signal from the infrared light receiving unit 5b.

  As described above, after receiving the disaster prevention signal, the automatic closing device 4 controls the operation of the brake releasing motor 41 according to the presence or absence of the infrared light receiving signal from the infrared light receiving portion 5b, so that the infrared light receiving portion 5b senses the infrared light. The height of the shutter curtain 6 can be controlled so that it can be done (that is, the infrared rays are not blocked by smoke). As a result, it is possible to secure an evacuation route while keeping the safety by lowering the shutter curtain 6 in accordance with the state of smoke generated by the disaster.

  When the automatic closing device 4 receives the obstacle detection signal from the detection unit 7b of the obstacle sensing device after receiving the disaster prevention signal, the automatic closing device 4 interrupts the operation of the brake releasing motor 41 and causes the brake mechanism 3 to brake. It is to make.

  The automatic closing device 4 is used for releasing the brake when receiving the obstacle detection signal from the detection unit 7b of the obstacle detection device even when the infrared light reception signal is not supplied from the infrared light reception unit 5b after receiving the disaster prevention signal. The operation of the motor 41 is interrupted and the brake mechanism 3 is braked. That is, the automatic closing device 4 can secure safety by giving priority to the reception of the obstacle detection signal over the reception of the infrared light reception signal.

  Here, FIG. 3 is a functional block diagram showing the internal configuration of the control means 1 and the connection relationship between the control means 1 and the automatic closing device 4. In addition, the code | symbol of the component requirement shown by FIG. 3 is a respectively corresponding component requirement.

  As illustrated in FIG. 3, the control unit 1 includes at least a power supply circuit 11, an auxiliary power supply 12, a power supply switching circuit 13, a switching unit 14, and a drive control unit 15.

  The power supply circuit 11 normally rectifies an external current supplied from an external power supply (not shown) and supplies the rectified current to the switching means 14 and the like.

  The auxiliary power supply 12 supplies current to the switching means 14 and the like instead of the external power supply when the external power supply is abnormal. Thereby, even when the supply of external power is interrupted, power can be supplied to the switching means 14 and the like, and the switch can be operated. As the configuration of the auxiliary power supply 12, for example, a battery that is charged while an external power supply is supplied (for example, a secondary battery) can be applied. As a result, the auxiliary capacity can be supplied after the external power supply is cut off.

  The power supply switching circuit 13 switches the connection to the auxiliary power supply 12 when the external power supply is cut off. The power supply switching circuit 13 includes, for example, a relay contact for power supply abnormality, and enables power supply switching by switching the contact to the auxiliary power supply 12 side when an external power supply abnormality is detected.

  The switching means 14 outputs a disaster prevention signal to the automatic closing device 4 when a disaster prevention signal is received from a control panel (not shown).

  The drive control unit 15 controls the function of the control unit 1, and is a control unit including, for example, an MPU, a RAM, a ROM, and the like, and includes at least a timer 15a.

  The timer 15a measures a predetermined time after receiving the disaster prevention signal in order to forcibly lower the shutter curtain 6 after the control means 1 gives the disaster prevention signal to the automatic closing device 4. When the timer 15a counts a predetermined time, the control means 1 further gives a forced brake release signal to the automatic closing device 4 so as to forcibly lower the shutter curtain 6.

  In this way, the control means 1 gives a forced brake release signal to the automatic closing device 4 so that after the disaster prevention signal is received and a predetermined time has elapsed, the brake is forcibly braked regardless of the infrared light receiving state of the infrared light receiving unit 5b. The brake of the mechanism 3 can be released and the shutter curtain 6 can be lowered. Thereby, safety can be ensured more.

(A-2) Operation | movement of embodiment Next, operation | movement of the disaster prevention shutter drive control system 10 of this embodiment is demonstrated with reference to drawings.

  FIG. 4 is an operation flowchart showing the operation of the disaster prevention shutter drive control system 10 of the present embodiment.

  First, in the disaster prevention shutter drive control system 10, the shutter curtain 6 is wound up at a normal time when a disaster prevention signal is not input from a control panel (not shown), and the wound shutter curtain 6 is stored. Further, the brake mechanism 3 applies a brake to the wound shutter curtain 6 so as not to lower its own weight.

  When a disaster occurs, a disaster detection sensor (not shown) connected to the control panel detects the disaster, and the control panel outputs a disaster prevention signal. And the disaster prevention signal from a control panel inputs into the control means 1 (step 1).

  When the disaster prevention signal is input to the control means 1, the control means 1 gives the disaster prevention signal to the automatic closing device 4.

  When the disaster prevention signal is given to the automatic closing device 4, in the automatic closing device 4, it is judged whether or not the obstacle detecting signal is given to the automatic closing device 4 from the detection unit 7b of the obstacle sensing device (step 2). ).

  When the obstacle detection signal is not given, it is determined in the automatic closing device 4 whether or not a forced brake release signal is given from the control means 1 to the automatic closing device 4 (step 3).

  When the forced braking release signal is not given from the control means 1 (that is, when the predetermined time has not elapsed after receiving the disaster prevention signal by the timer 15a), the infrared light receiving signal is automatically transmitted from the infrared light receiving unit 5b in the automatic closing device 4. It is judged whether or not it is given to the closing device 4 (step 4).

  When the infrared light receiving signal is given to the automatic closing device 4 from the infrared light receiving unit 5b (that is, when the infrared light receiving unit 5b receives infrared rays), the automatic closing device 4 receives the disaster prevention signal. The brake release motor 41 is not operated (step 5). Since the brake releasing motor 41 is not operated, the brake mechanism 3 remains braked on the shutter curtain 6 (step 6). Thereby, an evacuation route can be secured by not dropping the shutter curtain 6 immediately after the disaster occurs.

  On the other hand, in step 4, when the infrared light receiving signal is not given to the automatic closing device 4 from the infrared light receiving unit 5b, the automatic closing device 4 operates the brake releasing motor 41 (step 7). When the brake release motor 41 is activated, the brake mechanism 3 is activated, the brake applied to the shutter curtain 6 is released (step 8), and the shutter curtain 6 is lowered by its own weight (step 9).

Thereafter, it is determined whether or not the height of the shutter curtain 6 has reached a preset lower limit position. When the height of the shutter curtain 6 has reached the lower limit position, the process ends. The process is repeated until the lower limit position is reached (step 10).
Here, when the infrared light receiving unit 5b does not give an infrared light reception signal in step 4, for example, the case where the infrared light is blocked by smoke generated by a disaster can be considered.

  Therefore, when the brake is released (step 8), the shutter curtain 6 falls by its own weight to a height at which smoke does not stand (step 9), and the infrared light receiving unit 5b receives the infrared light again before reaching the lower limit position (step 4). The automatic closing device 4 interrupts the operation of the brake releasing motor 41 (step 5), the brake mechanism 3 brakes the shutter curtain 6 (step 6), and the shutter curtain 6 stops at a height where smoke does not stand. To do.

  As a result, even if the shutter curtain 6 starts to descend by its own weight, the shutter curtain 6 stops at a evacuable height where no smoke is standing, and the escape path (opening) is prevented while preventing the smoke from flowing out to other sections. Can be secured.

  In step 2, when the obstacle detection signal is given to the automatic closing device 4, the process proceeds to step 5 where the automatic closing device 4 does not operate the brake releasing motor 41 so that the shutter curtain 6 stops (step 5). ).

  In step 3, when a forced brake release signal is given to the automatic closing device 4, the automatic closing device 4 brakes the shutter curtain 6 so that its weight is lowered regardless of whether or not the infrared light reception signal is given. The release motor 41 is operated (step 7).

(A-3) Effects of the Embodiment As described above, according to the present embodiment, the shutter curtain 6 includes the infrared light transmitting unit 5a and the infrared light receiving unit 5b, and the automatic closing device 4 performs the shutter according to the presence or absence of the infrared light reception signal.

The part 5b can cope with disasters in both of the two spaces partitioned by the shutter curtain 6.

(B-3) In the above-described embodiment, it is described that the shutter curtain 6 is lowered by its own weight until the infrared light receiving signal is given after the infrared light receiving signal is not given from the infrared light receiving unit 5b.

  However, when the shutter curtain 6 is lowered by its own weight after the infrared light receiving signal is not given from the infrared light receiving unit 5b, the automatic closing device 4 applies a brake to the shutter curtain 6 with a predetermined drop width or drop time. The shutter curtain 6 may be lowered at every predetermined stage. The descending width and descending time can be variably set.

  Further, the automatic closing device 4 may be controlled so as to brake the shutter curtain 6 and decelerate the descending speed of the shutter curtain 6.

(B-4) In the above-described embodiment, the auxiliary power supply is activated after the disaster prevention signal is detected, and the disaster prevention shutter drive control system 10 is driven using the auxiliary power supply. However, the disaster prevention signal (for example, DC 24V) is used. The signal may be driven based on the input of the signal itself.

(B-5) In the automatic closing device 4 of the above-described embodiment, the processing according to the presence / absence of reception of the infrared light reception signal and the obstacle detection signal is based on the premise that the disaster prevention signal is received. Therefore, in embodiment mentioned above, the process of the automatic closing apparatus 4 after disaster prevention signal reception was demonstrated in detail.

  However, when the automatic closing device 4 does not receive the infrared light reception signal or the reception of the obstacle detection signal before receiving the disaster prevention signal, for example, the positions of the infrared light transmission unit 5a and the infrared light reception unit 5b are shifted. It may be possible to manage device settings under normal conditions such as not being positioned on the optical axis.

(B-6) In the above-described embodiment, the case where the present invention is applied to a self-closing shutter such as a disaster prevention shutter that falls by its own weight has been described, but it may be closed electrically. In this case, the closing direction is not limited to the downward direction, and can also be applied to a lateral direction, an upward direction, an oblique direction, a curved direction in which these plural directions are combined, and a rotational direction.

(B-7) In the above-described embodiment, the case where the opening / closing body control device of the present invention is applied to the disaster prevention shutter system has been described. However, the disaster prevention shutter is a shutter other than the disaster prevention shutter, door, automatic door, window, overhead door.
