JP 2007-169916 A

  As described above, the automatic window opening / closing system disclosed in Patent Document 1 includes a window opening / closing mechanism (automatic opening / closing mechanism) for automatically opening / closing a window and a window locking mechanism (automatic locking mechanism) for automatically locking a window. And. On the other hand, some automatic window opening / closing systems having an automatic opening / closing mechanism do not include an automatic locking mechanism. In general, the control method of the automatic window opening / closing system varies depending on whether the automatic window opening / closing system includes an automatic locking mechanism or not.

  That is, if the automatic window opening / closing system does not have an automatic locking mechanism, the automatic opening / closing mechanism may simply open a closed window, but the window automatic opening / closing system has an automatic locking mechanism. In this case, after confirming that the automatic locking mechanism unlocks the window, the automatic opening / closing mechanism must open the closed window. Therefore, in general, it is necessary to change the control software of the automatic window opening / closing system depending on whether the automatic window opening / closing system has an automatic locking mechanism or not. The versatility of becomes low.

  Then, the subject of this invention is providing the automatic opening / closing system of the fitting which can improve versatility in the automatic opening / closing system of the fitting provided with the opening / closing mechanism which opens / closes the fitting automatically.

  In order to solve the above-described problems, an automatic opening / closing system for a joinery according to the present invention supplies a current to an opening / closing mechanism that automatically opens and closes an openable / closable fitting and a first drive source that is a drive source of the opening / closing mechanism. A second drive for driving the second drive source by supplying a current to a first drive unit that drives the drive source and a second drive source that is a drive source of a locking mechanism that automatically locks the closed fitting. And a drive command unit that outputs a drive command signal of the second drive source to the second drive unit, and when opening the closed joinery, the drive command unit sets the joinery to an unlocked state. Drive command signal is output to the second drive unit, and after the drive command signal is input to the second drive unit, the first drive unit has a predetermined current value output from the second drive unit. When the threshold value is exceeded or the drive command signal is input to the second drive unit, the second drive If not output current from and drives the first driving source so fittings open.

  In the automatic opening / closing system for a joinery according to the present invention, when opening the closed joinery, a drive command signal for unlocking the joinery to the second drive unit for driving the second drive source of the locking mechanism. When the value of the current output from the second drive unit exceeds a predetermined threshold or the drive command signal is input to the second drive unit, the current from the second drive unit is Is not output, the first drive unit that drives the first drive source of the opening / closing mechanism drives the first drive source so that the fitting is opened.

  Therefore, in the present invention, when the automatic opening / closing system of a joinery includes a locking mechanism, the current supplied to the second drive source from the second drive unit when the locking member of the locking mechanism moves to the unlocked position. When the value of exceeds the predetermined threshold, the first drive source can be driven so that the joinery opens. In addition, when the automatic opening / closing system of the joinery is not provided with a locking mechanism, no current is output from the second drive unit even if a drive command signal is input to the second drive unit. Thus, it becomes possible to drive the first drive source.

  Therefore, in the present invention, when the automatic opening / closing system for a joinery includes a locking mechanism using common control software, the joinery in a closed state is moved after the locking member of the locking mechanism is moved to the unlocking position. When the automatic opening / closing system of the joinery is not provided with a locking mechanism, the joinery in the closed state can be opened as it is. That is, according to the present invention, it is possible to open a closed joinery using common control software depending on whether or not the automatic opening / closing system of the joinery has a locking mechanism. As a result, in the present invention, versatility of the automatic opening / closing system for joinery can be enhanced.

  In the present invention, when closing the joinery in the open state, the first drive unit drives the first drive source so that the joinery is closed, and when the joinery is closed, the drive command unit places the joinery in a locked state. The drive command signal is output to the second drive unit, and the control unit of the automatic opening and closing system of the joinery inputs the value of the current output from the second drive unit after the drive command signal is input to the second drive unit. It is preferable that the closing operation of the joinery is completed if the current exceeds the predetermined threshold value or if no current is output from the second drive unit despite the drive command signal being input to the second drive unit.

  If comprised in this way, when the automatic opening / closing system of a joinery is provided with the locking mechanism, the locking member of the locking mechanism moves to the locking position, and the current supplied from the second drive unit to the second drive source When the value exceeds a predetermined threshold value, the closing operation of the joinery is completed. When the automatic opening / closing system of the joinery is not provided with the locking mechanism, the closing operation of the joinery can be completed as it is. That is, when the automatic opening and closing system of the joinery has a locking mechanism using common control software, the closing operation of the fitting is completed after locking, and the automatic opening and closing system of the fitting has the locking mechanism. If not, the joinery closing operation can be completed as it is.

  In the present invention, when closing the joinery in the open state, the drive command unit outputs a drive command signal for bringing the joinery into an unlocked state to the second drive unit, and the first drive unit receives the drive command. After the signal is input to the second drive unit, if the value of the current output from the second drive unit exceeds a predetermined threshold value, or the drive command signal is input to the second drive unit, When no current is output from the second drive unit, it is preferable to drive the first drive source so that the fitting is closed.

  If comprised in this way, when the automatic opening / closing system of joinery is provided with the locking mechanism, the locking member of the locking mechanism moves to the unlocking position, and the current supplied from the second drive unit to the second drive source When the value of is over a predetermined threshold, the first drive source is driven so that the joinery closes, and when the automatic opening / closing system of the joinery does not include a locking mechanism, the first fitting is closed as it is. It becomes possible to drive the drive source. In other words, if the automatic opening and closing system for a joinery is equipped with a locking mechanism using common control software, the locking member of the locking mechanism is securely moved to the unlocked position, and then the fitting is closed and the automatic opening and closing of the fitting is performed. If the system does not include a locking mechanism, the joinery can be closed as it is.

  As described above, according to the present invention, in the automatic opening / closing system for a joinery including an opening / closing mechanism that automatically opens and closes the joinery, the versatility of the automatic opening / closing system for the joinery can be enhanced.

It is the schematic for demonstrating the structure of the automatic opening / closing system of the fitting concerning embodiment of this invention. It is a block diagram for demonstrating the structure of the control part of the automatic opening / closing system of the fitting shown in FIG. FIG. 2 is a flowchart for explaining an example of a control method of the automatic window opening / closing system when the opening / closing mechanism shown in FIG. 1 opens a closed window; It is a flowchart for demonstrating an example of the control method of the automatic opening / closing system of a window when the opening / closing mechanism shown in FIG. 1 closes the window of an open state.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Schematic configuration of automatic opening / closing system for joinery)
FIG. 1 is a schematic diagram for explaining the configuration of a joinery automatic opening / closing system 1 according to an embodiment of the present invention. FIG. 2 is a block diagram for explaining the configuration of the control unit 12 of the automatic opening / closing system 1 for joinery shown in FIG.

  The automatic opening / closing system 1 (hereinafter, referred to as “automatic opening / closing system 1”) of the present embodiment is a system for automatically opening and closing the window 2 that is a fitting that can be opened and closed. The window 2 is, for example, a vertical sliding window. The automatic opening / closing system 1 includes an opening / closing mechanism 3 that automatically opens and closes the window 2. Further, the automatic opening / closing system 1 of this embodiment may or may not include a locking mechanism 4 that automatically locks the closed window 2.

  The opening / closing mechanism 3 includes a motor 5 as a drive source. The opening / closing mechanism 3 includes, for example, a screw shaft (not shown) that is rotated by the power of the motor 5 and a moving member (not shown) having a nut member that engages with the screw shaft, and the screw shaft rotates. Then, the moving member moves in the axial direction of the screw shaft. The moving member moves between an open position where the window 2 is opened and a closed position where the window 2 is closed. A bearing (not shown) that rotatably supports the screw shaft and the motor 5 are attached to the window frame 6. One end of a link member (not shown) is rotatably connected to the moving member. The other end side of the link member is rotatably connected to a ridge surrounding the window glass 7. The motor 5 of this embodiment is a first drive source.

  The locking mechanism 4 includes a motor 8 as a drive source. The locking mechanism 4 transmits, for example, a locking member (not shown) that rotates between a locking position that locks the window 2 and an unlocking position that unlocks the window 2, and the power of the motor 8 to the locking member. Power transmission mechanism (not shown). When the automatic opening / closing system 1 includes the locking mechanism 4, the motor 8, the locking member, and the power transmission mechanism are attached to the window frame 6. The motor 8 of this embodiment is a second drive source.

  The control unit 12 of the automatic opening / closing system 1 supplies a first motor driver 13 that supplies current to the motor 5 to drive the motor 5, and a second motor driver 14 that supplies current to the motor 8 to drive the motor 8. And a microcomputer 15 to which the first motor driver 13 and the second motor driver 14 are connected. The microcomputer 15 outputs a drive command signal for the motor 5 to the first motor driver 13. Further, the microcomputer 15 outputs a drive command signal for the motor 8 to the second motor driver 14. The first motor driver 13 of this embodiment is a first drive unit, the second motor driver 14 is a second drive unit, and the microcomputer 15 is a drive command unit.

  The control unit 12 includes a current detection resistor 16 for detecting the value of the current output from the second motor driver 14 and a potential detection circuit 17 for detecting the potential of the current detection resistor 16. The potential detection circuit 17 is connected to the microcomputer 15. The microcomputer 15 detects the value of the current output from the second motor driver 14 based on the output signal of the potential detection circuit 17. The control unit 12 includes a current detection resistor (not shown) for detecting the value of the current output from the first motor driver 13, and a potential detection circuit (not shown) that detects the potential of the current detection resistor. The microcomputer 15 also detects the value of the current output from the first motor driver 13.

  The control unit 12 is mounted on a circuit board (not shown). A connector (circuit board side connector) for electrically connecting the motor 8 to the circuit board is mounted on the circuit board. When the automatic opening / closing system 1 includes the locking mechanism 4, a connector (a connector on the motor 8 side) attached to the tip of the cable of the motor 8 is connected to the connector on the circuit board side. On the other hand, when the automatic opening / closing system 1 does not include the locking mechanism 4, the connector on the motor 8 side is not connected to the connector on the circuit board side.

(Control method of automatic switching system)
FIG. 3 is a flowchart for explaining an example of a control method of the automatic opening / closing system 1 when the opening / closing mechanism 3 shown in FIG. 1 opens the closed window 2. FIG. 4 is a flowchart for explaining an example of a control method of the automatic opening / closing system 1 when the opening / closing mechanism 3 shown in FIG. 1 closes the opened window 2.

  When the opening / closing mechanism 3 opens the window 2 in the closed state, for example, an “open” button of a remote controller (not shown) of the automatic opening / closing system 1 is pressed by the user, and the microcomputer 15 receives a start signal for opening the window 2. As a result, the opening operation of the window 2 is started. When the opening operation of the window 2 is started, as shown in FIG. 3, the microcomputer 15 outputs a drive command signal for the motor 8 for bringing the window 2 into an unlocked state to the second motor driver 14 ( Step S1). Thereafter, the microcomputer 15 determines whether or not the value of the current output from the second motor driver 14 exceeds a predetermined threshold th1, and whether or not the current is output from the second motor driver 14. Judgment is made (step S2).

  When the automatic opening / closing system 1 includes the locking mechanism 4, when the locking member of the locking mechanism 4 finishes rotating to the unlocking position, the load acting on the motor 8 increases, and thus the second motor driver 14 outputs the load. The value of the current (that is, the current supplied from the second motor driver 14 to the motor 8) exceeds the threshold th1. When the automatic opening / closing system 1 does not include the locking mechanism 4, no current is output from the second motor driver 14 because the connector on the motor 8 side is not connected to the connector on the circuit board side. Therefore, in step S2, if the value of the current output from the second motor driver 14 exceeds the threshold th1, or if no current is output from the second motor driver 14, the control unit 12 unlocks the window 2. Is completed (step S3).

  Thereafter, the microcomputer 15 outputs a drive command signal for the motor 5 for opening the window 2 to the first motor driver 13 (step S4). Thereafter, the microcomputer 15 determines whether or not the value of the current output from the first motor driver 13 exceeds a predetermined threshold th2 (step S5). When the moving member of the opening / closing mechanism 3 moves to the open position, the load acting on the motor 5 increases, so that the current output from the first motor driver 13 (that is, the current supplied from the first motor driver 13 to the motor 5). ) Exceeds the threshold th2. Therefore, when the value of the current output from the first motor driver 13 exceeds the threshold th2 in step S5, the control unit 12 determines that the window 2 has been opened and completes the opening operation of the window 2. .

  Thus, when opening the closed window 2, the microcomputer 15 outputs a drive command signal for bringing the window 2 into an unlocked state to the motor driver 14. Further, after the drive command signal for bringing the window 2 into the unlocked state is input to the motor driver 14, the current value output from the motor driver 14 exceeds the threshold th1 or the window 2 is in the unlocked state. If a current is not output from the motor driver 14 even though the drive command signal for the above is input to the motor driver 14, the motor driver 13 drives the motor 5 so that the window 2 opens.

  When the opening / closing mechanism 3 closes the opened window 2, for example, a “close” button on the remote control is pressed by the user, a start signal for closing the window 2 is input to the microcomputer 15, and the window 2 is closed. Operation starts. When the closing operation of the window 2 is started, as shown in FIG. 4, the microcomputer 15 outputs a drive command signal for the motor 8 for bringing the window 2 into an unlocked state to the second motor driver 14 ( Step S11). Thereafter, the microcomputer 15 determines whether or not the value of the current output from the second motor driver 14 exceeds the threshold th1 and determines whether or not the current is output from the second motor driver 14. (Step S12).

  As described above, when the automatic opening / closing system 1 includes the locking mechanism 4, when the locking member of the locking mechanism 4 finishes rotating to the unlocking position, the value of the current output from the second motor driver 14 becomes the threshold value. It exceeds th1. In addition, when the automatic opening / closing system 1 does not include the locking mechanism 4, no current is output from the second motor driver 14. Therefore, in step S12, if the value of the current output from the second motor driver 14 exceeds the threshold th1, or if no current is output from the second motor driver 14, the control unit 12 unlocks the window 2. Is completed (step S13).

  Thereafter, the microcomputer 15 outputs a drive command signal for the motor 5 for closing the window 2 to the first motor driver 13 (step S14). Thereafter, the microcomputer 15 determines whether or not the value of the current output from the first motor driver 13 exceeds the threshold th2 (step S15). When the moving member of the opening / closing mechanism 3 moves to the closed position, the load acting on the motor 5 increases, so the value of the current output from the first motor driver 13 exceeds the threshold th2. Therefore, when the value of the current output from the first motor driver 13 exceeds the threshold th2 in step S15, the control unit 12 determines that the window 2 has been closed (step S16). Note that the threshold th2 in step S5 and the threshold th2 in step S15 may be different.

  Thereafter, the microcomputer 15 outputs a drive command signal for the motor 8 for bringing the window 2 into the locked state to the second motor driver 14 (step S17). Thereafter, the microcomputer 15 determines whether or not the value of the current output from the second motor driver 14 exceeds the threshold th1 and determines whether or not the current is output from the second motor driver 14. (Step S18). Note that the threshold value th1 in steps S2 and S12 may be different from the threshold value th1 in step S18.

  When the automatic opening / closing system 1 includes the locking mechanism 4, when the locking member of the locking mechanism 4 finishes rotating to the locking position, the load acting on the motor 8 increases, and thus the second motor driver 14 outputs the load. The current value exceeds the threshold th1. When the automatic opening / closing system 1 does not include the locking mechanism 4, no current is output from the second motor driver 14 because the connector on the motor 8 side is not connected to the connector on the circuit board side. Therefore, in step S18, if the value of the current output from the second motor driver 14 exceeds the threshold th1, or if no current is output from the second motor driver 14, the control unit 12 unlocks the window 2. And the closing operation of the window 2 is completed.

  Thus, when closing the opened window 2, the microcomputer 15 first outputs a drive command signal for bringing the window 2 into an unlocked state to the motor driver 14. Further, after the drive command signal for bringing the window 2 into the unlocked state is input to the motor driver 14, the current value output from the motor driver 14 exceeds the threshold th1 or the window 2 is in the unlocked state. If a current is not output from the motor driver 14 even though the drive command signal is input to the motor driver 14, the motor driver 13 drives the motor 5 so that the window 2 is closed.

  When the window 2 is closed, the microcomputer 15 outputs a drive command signal for bringing the window 2 into a locked state to the second motor driver 14. When the drive command signal for setting the window 2 in the locked state is input to the second motor driver 14 after the current value output from the second motor driver 14 exceeds the threshold th1, If a drive command signal for locking the window 2 is input to the motor driver 14 and no current is output from the motor driver 14, the closing operation of the window 2 is completed.

(Main effects of this form)
As described above, in this embodiment, when the closed window 2 is opened, a drive command signal for bringing the window 2 into an unlocked state is input to the motor driver 14 and then output from the motor driver 14. If the current value exceeds the threshold th1, or the motor driver 14 does not output current even though the drive command signal for unlocking the window 2 is input to the motor driver 14, the motor The driver 13 drives the motor 5 so that the window 2 opens.

  For this reason, in this embodiment, when the automatic opening / closing system 1 includes the locking mechanism 4 using common control software, the window is closed after the locking member of the locking mechanism 4 is moved to the unlocking position. 2 can be opened, and when the automatic opening / closing system 1 is not provided with the locking mechanism 4, the closed window 2 can be opened as it is. That is, in this embodiment, the closed window 2 can be opened using common control software depending on whether the automatic opening / closing system 1 includes the locking mechanism 4 or not. Therefore, in this embodiment, the versatility of the automatic opening / closing system 1 can be enhanced.

  In this embodiment, when closing the opened window 2, the microcomputer 15 first outputs a drive command signal for bringing the window 2 into an unlocked state to the motor driver 14. Further, after the drive command signal for bringing the window 2 into the unlocked state is input to the motor driver 14, the current value output from the motor driver 14 exceeds the threshold th1 or the window 2 is in the unlocked state. If a current is not output from the motor driver 14 even though the drive command signal is input to the motor driver 14, the motor driver 13 drives the motor 5 so that the window 2 is closed.

  Therefore, in this embodiment, when the automatic opening / closing system 1 includes the locking mechanism 4 using common control software, the locking member of the locking mechanism 4 is moved to the unlocking position and then opened. If the automatic opening / closing system 1 is not provided with the locking mechanism 4, the opened window 2 can be closed as it is.

  In this embodiment, when the opened window 2 is closed, the microcomputer 15 outputs a drive command signal for bringing the window 2 into a locked state to the second motor driver 14. In addition, after the drive command signal for setting the window 2 in the locked state is input to the second motor driver 14, the control unit 12 exceeds the threshold th1 when the current value output from the second motor driver 14 exceeds the threshold th1. Alternatively, the window 2 closing operation is completed when no current is output from the motor driver 14 even though a drive command signal for locking the window 2 is input to the motor driver 14.

  Therefore, in this embodiment, when the automatic opening / closing system 1 includes the locking mechanism 4 using common control software, the locking member of the locking mechanism 4 is moved to the locking position (that is, locking is performed). After the closing operation of the window 2 can be completed, and the automatic opening / closing system 1 does not include the locking mechanism 4, the closing operation of the window 2 can be completed as it is.

  In this embodiment, even if the automatic opening / closing system 1 includes the locking mechanism 4, the opening / closing mechanism 3 and the locking mechanism 4 do not operate simultaneously. Therefore, in this embodiment, it becomes possible to reduce the maximum power required in the automatic opening / closing system 1.

(Other embodiments)
The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited to this, and various modifications can be made without departing from the scope of the present invention.

  In the above-described embodiment, when the current is not output from the second motor driver 14 in step S2 when the automatic opening / closing system 1 is operated for the first time after installation, in the subsequent control of the automatic opening / closing system 1, Steps S1 to S3, S11 to S13, S17, and S18 may be omitted. That is, if it is determined in step S2 that no current is output from the second motor driver 14 and the automatic opening / closing system 1 is not provided with the locking mechanism 4, the control of the automatic opening / closing system 1 thereafter includes step S1. To S3, S11 to S13, S17, and S18 may be omitted.

  Further, when the microcomputer 15 detects the current output from the second motor driver 14 in step S2 when the automatic opening / closing system 1 is operated for the first time after installation, In steps S2, S12, and S18, the microcomputer 15 does not have to determine whether or not a current is output from the second motor driver 14. That is, in step S2, when the microcomputer 15 detects the current output from the second motor driver 14 and determines that the automatic opening / closing system 1 includes the locking mechanism 4, the subsequent automatic opening / closing system 1 In this control, in steps S2, S12, and S18, the microcomputer 15 does not need to determine whether or not a current is output from the second motor driver 14.

  Similarly, when the automatic opening / closing system 1 is operated for the first time after installation, if no current is output from the second motor driver 14 in step S12, in the subsequent control of the automatic opening / closing system 1, step S1 is performed. To S3, S11 to S13, S17, and S18 may be omitted. When the microcomputer 15 detects the current output from the second motor driver 14 in step S12 when the automatic opening / closing system 1 is operated for the first time after installation, In steps S2, S12, and S18, the microcomputer 15 does not have to determine whether or not a current is output from the second motor driver 14.

  In the embodiment described above, a plurality of motors 8 may be connectable to a circuit board on which the control unit 12 is mounted. That is, the automatic opening / closing system 1 may include a plurality of locking mechanisms 4 that automatically lock the window 2. In this case, the control unit 12 includes a plurality of second motor drivers 14 that drive each of the plurality of motors 8. In this case, the microcomputer 15 outputs a drive command signal to each of the plurality of second motor drivers 14 in steps S1, S11, and S17.

  In this case, the microcomputer 15 determines whether or not the value of the current output from the second motor driver 14 exceeds the threshold th1 in steps S2, S12, and S18, and the current from the second motor driver 14. Is sequentially determined for each of the plurality of second motor drivers 14. Alternatively, the microcomputer 15 determines whether or not the value of the current output from the second motor driver 14 exceeds the threshold th1 in steps S2, S12, and S18, and the current is output from the second motor driver 14. Whether or not the plurality of second motor drivers 14 are simultaneously determined.

  In the above-described embodiment, even if the automatic opening / closing system 1 includes the locking mechanism 4, if the window 2 need not be automatically locked when the opened window 2 is closed, Steps S17 and S18 may be omitted. Moreover, in the form mentioned above, even if it is a case where the automatic opening / closing system 1 is provided with the locking mechanism 4, it is not assumed that the locking member of the locking mechanism 4 moves to the locking position with the window 2 open. In this case, steps S11 to S13 may be omitted.

  In the embodiment described above, it is detected that the window 2 is opened and the window 2 is closed based on the value of the current output from the first motor driver 13, but the open / closed state of the window 2 is detected. It may be detected that the window 2 is opened and the window 2 is closed by the sensor. That is, the automatic opening / closing system 1 may include a sensor that detects the open / closed state of the window 2. In this case, the open / closed state of the window 2 is detected in steps S5 and S15 based on the detection result of the sensor.

  In the above-described embodiment, when the automatic opening / closing system 1 includes the locking mechanism 4, the automatic opening / closing system 1 may include a sensor that detects the locking / unlocking state of the window 2. In this case, when the detection signal of this sensor is not input to the microcomputer 15, it is determined that the window 2 is unlocked. When the detection signal of this sensor is input to the microcomputer 15, the window 2 is locked. It is judged that. Even in this case, in steps S2, S12, and S18, the microcomputer 15 determines whether or not the value of the current output from the second motor driver 14 exceeds the predetermined threshold th1, and the second motor. It is determined whether or not current is output from the driver 14.

  In the embodiment described above, the drive source of the opening / closing mechanism 3 may be a solenoid. Similarly, the drive source of the locking mechanism 4 may be a solenoid. In the embodiment described above, the joinery that the automatic opening / closing system 1 opens and closes may be a window 2 such as a sliding window, a side sliding window, an outside fall window, or an inside fall window. Further, the joinery that the automatic opening / closing system 1 opens and closes may be a joinery other than the window 2 such as a door, a sliding door, or a shutter.
