The shaft 31 and the slat 10 wound around the shaft 31 are accommodated in the shutter box 30.

Next, the structure of the shutter curtain 20 will be described with reference to FIGS. 2A and 2B. 2A and 2B are cross-sectional views of the plurality of slats 10 connected to each other as viewed from the side.
The slat 10 has a movable wing 100 and a fixed wing 101. The movable wing 100 has a lower front hook 100a, an upper front hook 100b, and a middle front hook 100c formed at the upper end.
The fixed wing 101 has an upper rear hook 101a at the upper end and a lower rear hook 101b and a protrusion 101c at the lower end. In addition, the fixed wing 101 has an opening 101d as shown in FIGS. 2A and 2B. Next, the slat 10 connected to the upper side and the lower side will be described. The protrusion 101 c provided on the fixed wing 101 of the upper slat 10 and the upper front hook 100 b are engaged with the upper front hook 101 b provided on the movable wing 100 of the lower slat 10. The lower front hook 100 a and the middle front hook 100 c of the movable wing 100 of the lower slat 10 are engaged with the upper rear hook 101 a provided on the fixed wing 101 of the lower slat 10.

When the movable wing 100 is in the closed state, the opening 101d is in the closed state, so that light and wind from the outside cannot pass through the opening 101d to the indoor side.

FIG. 2B is a cross-sectional view of the shutter curtain 20 in a state where the movable wing 100 is open. In this figure, when the shutter curtain 20 is in a closed state (a state where the baseboard of the shutter curtain 20 is in contact with the floor surface), based on the relative movement between the upper slat 10 and the lower slat 10, This represents a state where the movable wing 100 is in an open state. The movable wing 100 is positioned so as to have an angle with respect to the fixed wing 101.
This relative movement can be performed, for example, when the lower slat 10 is pressed by the upper slat 10.
When the movable wing 100 is in the open state, the opening 101d is in the open state, and light and wind from the outside can pass through the opening 101d to the indoor side.
Here, after the shutter curtain 20 is in the closed state, the motor 32 is rotated forward by a predetermined number of revolutions so as to further unwind the shutter curtain 20, whereby the tip portion x of the protrusion 101c of the upper slat 10 is moved. By pressing the indoor side of the contact surface y of the movable wing 100 of the lower slat 10, the movable wing 100 is opened with the upper end portion (upper rear hook 101a) of the fixed wing of the lower slat 10 as a fulcrum. It becomes a state. In addition, after the movable wing 100 is in the open state, the motor 32 rotates reversely by a predetermined number of rotations so as to wind up the shutter curtain 20, so that the tip portion x of the protrusion 101c of the upper slat 10 is lowered. By moving away from the contact surface y of the movable wing 100 of the slat 10 on the side, the movable wing 100 is in a closed state (FIG. 2A).

FIG. 3 is a functional block diagram showing functions of the shutter device 1. In this figure, the shutter device 1 includes an operation unit (input unit) 200, a control device 300, a detection unit 400, and a motor 32.
The operation unit 200 is connected to the control device 300. The operation unit 200 is provided with an open switch 201, a stop switch 202, and a close switch 203. The user can perform normal operation or ventilation operation of the shutter curtain 20 by pressing these switches. The normal operation is an operation of closing the shutter curtain 20 and an operation of stopping the operation of the shutter curtain 20 during the opening / closing operation. The ventilation operation is an operation of opening the movable wing 100 of the slat 10 as described above. When any switch is pressed by the user, the operation unit 200 outputs a switch signal that is a signal corresponding to the switch to the control device 300. The communication between the operation unit 200 and the control device 300 may be wired or wireless.

The detection unit 400 detects that the skirting board of the shutter curtain 20 is in contact with the floor surface. The detection unit 400 has a function of detecting, for example, the driving state (for example, load) of the motor 32.
The detection unit 400 acquires position pulses from, for example, an encoder (not shown) built in the motor 32. The position pulse obtained from the encoder is output every time the motor 32 rotates by a predetermined amount. Further, the position pulse from the encoder increases in pulse width as the rotational speed of the motor 32 decreases, and decreases in pulse width as the rotational speed of the motor 32 increases. Therefore, the detection unit 400 calculates the rotational speed of the motor 32 as a load by counting the position pulses obtained from the encoder. The detection unit 400 may detect the rotation speed of the motor 32 as a load by obtaining the pulse width of the position pulse from the encoder. The detection unit 400 outputs the detection result to the control device 300.

The control device 300 is connected to each of the operation unit 200, the motor 32, and the detection unit 400. The control device 300 includes, for example, a CPU (Central Processing Unit), a storage device, and the like, and controls driving of the motor 32 according to the operation of the switch of the operation unit 200.
The control device 300 includes a control unit 301 and a driver 302.
The control unit 301 has a first mode in which the shutter curtain 20 and the movable wing 100 are closed, a second mode in which the movable wing is opened based on relative movement from the state in which the shutter curtain is closed, There is a third mode in which the motor 32 is rotated in the reverse direction so that the movable wing opened in the second mode is closed again.
Further, the control unit 301 can shift to the second mode when receiving an instruction to shift to the second mode from the operation unit 200 after the shutter curtain 20 is closed in the first mode. is there. For example, the control unit 301 uses the driver 302 in response to a switch operation (hereinafter referred to as “switch operation”) of the operation unit 200 performed by the user in a state where the shutter curtain 20 has shifted from the open state to the closed state. The driving of the motor 32 is controlled. More specifically, the control unit 301 determines which switch of the operation unit 200 is pressed based on a switch signal obtained from the operation unit 200. The control unit 301 receives the switching signal from the operation unit 200, counted by the timer provided in itself, based on whether received continuously switch signal preset time above T ₁ pressed It is determined whether or not the pressed switch is pressed and held.
In addition, when the control unit 301 receives two or more different types of switch signals during a preset time T ₂ (≦ T ₁ ) after timing, the user turns on the plurality of switches of the operation unit 200 together. It is determined that the button has been pressed.

When the control unit 301 determines that the user presses the open switch 201 of the operation unit 200 for a short time, the control unit 301 drives the motor 32 to wind the shutter curtain 20 around the shaft 31 and raises the command (hereinafter referred to as “open command”). .) To the driver 302. When the control unit 301 determines that the user has pressed the close switch 203 of the operation unit 200 for a short time, the control unit 301 drives the motor 32 to unwind the shutter curtain 20 from the shaft 31 and lowers the command (hereinafter referred to as a “close command”). .) To the driver 302. When the user presses the stop switch 202 of the operation unit 200 for a short time, the control unit 301 outputs a command (stop command) to stop the operation of the shutter curtain 20 by stopping the driving of the motor 32 to the driver 302. . Note that, for example, the control unit 301 determines that the switch is pressed, if not received continuously switch signal preset time above T ₁ is short pressed.

In addition, when the user performs a switch operation (hereinafter referred to as “slat switching switch operation”) different from the switch operation for performing the normal operation described above, the control unit 301 moves the movable wing 100 of the slat 10 to the motor 32. A command to operate (hereinafter referred to as “turn command”) is output to the driver 302. The slat selector switch operation is, for example, an operation of long-pressing any one predetermined switch of the operation unit 200 or an operation of pressing a plurality of different switches of the operation unit 200 together. The long pressing operation of the switch of the operation unit 200 may be any one of the open switch 201, the stop switch 202, and the close switch 203.
The operation of pressing down a plurality of different switches of the operation unit 200 may be performed by pressing at least two of the open switch 201, the stop switch 202, and the close switch 203. Note that a dedicated switch for shifting the shutter curtain 20 from the closed state to the ventilated state may be provided in the operation unit 200.

The control unit 301 acquires the load from the detection unit 400 at regular intervals while performing the operation of closing the shutter curtain 20. The control unit 301 detects whether or not the shutter curtain is in a closed state by determining whether or not the acquired load is equal to or greater than a full-close threshold. The fully closed threshold value is a value for determining that the shutter curtain 20 is closed, and is a load value of the motor 32 when the baseboard of the shutter curtain 20 comes into contact with the floor surface. The fully closed threshold is determined according to the moving distance of the shutter curtain 20 from the open state to the closed state, for example. The position pulse obtained from the encoder becomes higher than the load of the motor during normal operation when the base plate of the shutter curtain 20 comes into contact with the floor surface, so that the pulse width increases and the rotation speed decreases.
When the load acquired from the detection unit 400 is equal to or greater than the full-close threshold, the control unit 301 determines that the baseboard of the shutter curtain 20 is in contact with the floor surface. In this case, the control unit 301 outputs a stop command to the driver 302, and the operation of the shutter curtain 20 is stopped. On the other hand, when the load acquired from the detection unit 400 is less than the full-close threshold, the control unit 301 determines that the shutter curtain 20 is not closed and continues outputting the close command to the driver 302. The control unit 301 determines the position of the shutter curtain 20 from the motor load and fluctuations of the load, that is, the opened state (fully opened state, fourth mode) where the shutter curtain 20 is wound up, and the closed state (fully closed state, 1 mode), a pause state, or a ventilation state (second mode). This temporary stop state can be determined by detecting whether or not the stop switch 202 is pressed before reaching the closed state or the open state during the closing operation or the opening operation.

When the shutter curtain 20 is in the closed state, the control unit 301 specifies a preset number N and outputs a turning command to the motor 32 when the user performs a step changeover switch operation. The number N is the number of rotations of the motor 32 necessary to change the shutter curtain 20 from the closed state to the ventilated state, and is set in advance based on the results of experiments and the like.
In addition, when the shutter curtain 20 is in a ventilated state, the control unit 301 specifies a preset number N and outputs a reverse turn command to the motor 32 when the user performs a step changeover switch operation. The reverse turning command is a command for causing the motor 32 to operate the movable wing 100 of the slat 10 in the reverse direction, that is, to make it close.

  The driver 302 controls the motor 32 by generating a drive signal for the motor 32 and outputting the drive signal to the motor 32 based on a command from the control unit 301. The driver 302 maintains a predetermined rotation speed regardless of the load variation during the opening operation or the closing operation of the shutter curtain 20. When the shutter curtain 20 is in the closed state, the driver 302 receives the turning command and rotates the motor 32 by the number N in the unwinding direction. As a result, the shutter curtain 20 enters a ventilation state. On the other hand, when the shutter curtain 20 is in a ventilated state, when the driver 302 receives a reverse turning command, the driver 302 rotates the motor 32 by the number N in the winding direction. Thus, the shutter curtain 20 is closed.

Next, the operation of the control device 300 of the shutter device will be described based on the flowchart of FIG. FIG. 4 is a flowchart of the operation of the shutter curtain 20 in the present embodiment. Here, a case where the shutter curtain 20 is in an open state will be described as an initial state of the shutter curtain 20.
In step S <b> 100, the control unit 301 determines whether or not a closing operation switch signal is input from the operation unit 200 when the user presses the closing switch 203. When the control unit 301 determines that the closing operation switch signal is not input from the operation unit 200 (step S100: NO), the control unit 301 performs the determination in step S100 again. When the control unit 301 determines that the closing operation switch signal is input from the operation unit 200 (step S100: YES), the control unit 301 outputs a closing command to the driver 302. The driver 302 transmits the drive signal based on the close command to the motor 32 to drive the motor 32 in the unwinding direction. Thereby, since the shaft 31 connected to the motor 32 rotates in the unwinding direction, the slat 10 wound around the shaft 31 is unwound and the closing operation of the shutter device 1 is performed.

  In step S <b> 101, the control unit 301 acquires a detection result of the motor load from the detection unit 400 at regular intervals during the closing operation of the shutter curtain 20, and determines whether or not the threshold value is equal to or greater than the fully closed threshold. When the motor load is less than the fully closed threshold (step S101: NO), the control unit 301 continues the closing operation of the shutter curtain 20. If the motor load is equal to or greater than the fully closed threshold (step S101: YES), the process proceeds to step S102. The control unit 301 continues the closing operation of the shutter curtain 20 until the detection result of the motor load becomes equal to or greater than the fully closed threshold value.

In step S <b> 102, the control unit 301 outputs a stop command to the driver 302.
Based on the stop command, the driver 302 stops the output of the drive signal to the motor 32 and stops the rotation of the motor 32. Thereby, the closing operation of the shutter curtain 20 is stopped.
In step S <b> 103, the control unit 301 determines whether a switch signal corresponding to the user's step changeover switch operation is detected from the operation unit 200. When the control unit 301 does not detect the user's step change switch operation (step S103: NO), the control unit 301 proceeds to step S104. On the other hand, the control part 301 progresses to step S106, when a user's step change switch operation is detected (step S103: YES).

In step S <b> 104, the control unit 301 determines whether the operation unit 200 has detected a switch signal corresponding to the opening operation from the operation unit 200. When the control unit 301 does not detect the opening operation switch signal from the operation unit 200 (step S104: NO), the control unit 301 returns to step S103. On the other hand, when the control unit 301 detects an opening operation (step S104: YES), the control unit 301 proceeds to step S105.
In step S <b> 105, the control unit 301 outputs an open command to the driver 302. The driver 302 rotates the motor 32 in the winding direction by transmitting a drive signal based on the opening command to the motor 32. Here, the shutter device 1 continues the opening operation until the shutter curtain 20 is fully opened.

  In step S <b> 106, the control unit 301 determines whether or not the shutter curtain 20 is in a closed state based on whether or not the detection result of the load of the motor 32 is equal to or greater than the fully closed threshold value. When the shutter curtain is in the closed state (step S106: YES), the control unit 301 proceeds to step S107. On the other hand, when the shutter curtain is not in the closed state (step S106: NO), the control unit 301 proceeds to step S108.

  In step S <b> 107, the control unit 301 designates a preset number N and outputs a turning command to the motor 32. The driver 302 transmits a drive signal based on the turning command to the motor 32, so that the motor 32 rotates N times in the unwinding direction. Therefore, the shaft 31 connected to the motor 32 rotates in the N rotation unwinding direction. However, the control unit 301 cannot close the shutter curtain 20 because the baseboard of the shutter curtain 20 is in contact with the floor surface. For this reason, in the shutter curtain 20, the lower slat 10 is pressed by the upper slat 10, the movable wing 100 is opened, and the ventilation is performed. When the control unit 301 closes the shutter curtain 20, the process proceeds to step S103.

  In step S <b> 108, the control unit 301 specifies a preset number of times N and outputs a reverse turn command to the motor 32 via the driver 302. The motor 32 rotates N times in the winding direction based on this signal. For this reason, in the shutter curtain 20, the lower slat 10 is not pressed by the upper slat 10, and the movable wing 100 is closed.

  In step S109, the process proceeds to step S103 until the power supply to the shutter device 1 is stopped. When the power supply is stopped, the control device 300 ends the operation.

Next, the relationship between the switch of the operation unit 200 and the state of the shutter curtain 20 (open state, closed state, pause state, ventilation state) will be described with reference to FIG.
In step S201, when the user presses the open switch 201 when the shutter curtain 20 is in the open state, the shutter curtain 20 is already in the open state, and thus the closing operation is not performed. On the other hand, when the user presses the close switch 203, the shutter curtain 20 is closed and the closed state is entered (step S202). However, if the user presses the stop switch 202 during the closing operation of the shutter curtain 20, the control device 300 stops the closing operation of the shutter curtain 20. That is, the closed state is maintained halfway (step S203).

  When the shutter curtain 20 is in the closed state, if the user presses the close switch 203, the shutter curtain 20 is already in the closed state and does not operate (step S204). When the user presses the open switch 201, the shutter curtain 20 is opened to enter an open state (step S205). When the user operates the step changeover switch on the operation unit 200, the shutter curtain 20 enters the ventilation state (step S206).

When the shutter curtain 20 is in a ventilated state and the user presses the open switch 201, the shutter curtain 20 is opened to enter an open state (step S207). Here, when the user presses the stop switch 202 during the opening operation of the shutter curtain 20, the control device 300 stops the opening operation of the shutter curtain 20, and the shutter curtain 20 stops. That is, the closed state is maintained halfway (step S208).
FIG. 6 is a diagram illustrating another example of the operation flow of the state transition of the switch of the operation unit 200 and the shutter curtain 20 according to the embodiment of the present invention. As shown in FIG. 6, when the shutter curtain 20 is in the ventilation state, when the user operates the step changeover switch on the switch of the operation unit 200, the shutter curtain 20 is closed. As described above, when the shutter curtain 20 is in the ventilation state, the shutter device 1 can shift the shutter curtain 20 to the closed state or the open state in accordance with the switch operation of the operation unit 200. Therefore, when the shutter curtain 20 is in a ventilated state, the shutter device 1 shifts the shutter curtain 20 to the closed state when the user performs an operation other than pressing the open switch 201 (for example, a step changeover switch operation). be able to.

Next, the effect of this embodiment will be described. FIG. 7 is a diagram illustrating an operation flow of transition between the switch of the operation unit and the shutter curtain state (open state, closed state, pause state, ventilation state) in the conventional shutter device.
In the conventional shutter device, when the user depresses the close switch when the shutter curtain is in the open state, the shutter curtain is closed to enter the ventilation state. When the shutter curtain is in a ventilated state, when the user presses the open switch, the shutter curtain is opened and the shutter curtain is opened.
Thus, in the conventional shutter device, there is no mode in which the shutter curtain is closed. Therefore, when it is desired to close the shutter curtain, the user needs to manually press the stop switch with good timing while the shutter curtain is raised and lowered.
However, for example, when the shutter curtain shifts from the ventilated state to the open state, if the timing when the user presses the stop switch is delayed, a gap is generated between the shutter curtain and the floor surface. In addition, when the shutter curtain transitions from the open state to the ventilated state, if the timing when the user presses the stop switch is delayed, the slat movable wing 100 is activated and the slat opening is opened. Thus, when the user closes or opens the movable wing 100 of the shutter curtain, the operation is complicated in the conventional apparatus.
However, as described above, according to the present embodiment, the control device 300 has two modes of the first mode and the second mode, and changes the shutter curtain 20 from the open state to the closed state. Further, when the shutter curtain 20 is in the closed state, the control device 300 can set the ventilation state in which the movable wing 100 of the slat 10 is operated based on the switch signal of the step changeover switch operation from the operation unit 200. Further, when the shutter curtain 20 is in a ventilated state, the control device 300 operates the movable wing 100 of the slat 10 in the reverse direction based on the switch signal of the step change switch operation supplied from the operation unit 200, and the shutter curtain 20. Can be closed. Thereby, when a user makes the shutter curtain 20 a closed state, operation does not become complicated. Also, the control device 300 can have further modes.
Further, as described above, according to the present embodiment, the switch of the existing operation unit 200 is used as it is, and the switch operation of a pattern different from the normal operation of the shutter curtain 20 (for example, the operation of pressing both switches together) ), The shutter curtain 20 can be changed from the closed state to the ventilated state. Thus, it is not necessary to provide a new switch.

In addition, this invention is not restricted to the above-mentioned embodiment, In the range which does not deviate from the meaning of this invention, what added the various change to the above-mentioned embodiment is included.
In the present embodiment, as a method for detecting that the skirting board of the shutter curtain 20 is in contact with the bottom surface, the control device 300 determines whether or not the load calculated by the detection unit 400 from the encoder position pulse is equal to or greater than the full-close threshold. However, the present embodiment is not limited to this.
For example, a contact sensor or an optical sensor that detects contact with an object may be used. When the sensor is used, the sensor is disposed at either the lower end of the shutter curtain 20 or the lower end of the guide rails 40 and 50. When the lower end portion of the shutter curtain 20 reaches the floor surface by the closing operation of the shutter curtain 20, for example, the sensor changes from an off state to an on state. The control device 300 stops the motor 32 by detecting this on / off state change. In addition, the control device 300 stores in advance in a storage unit (not shown) the number of times the motor 32 is rotated until the shutter curtain 20 changes from the open state to the closed state (hereinafter referred to as “total number of closes”). Keep it. When performing the closing operation from the fully open state, the control device 300 reads the number of full closures stored in advance in the storage unit, and rotates the motor 32 until the number of rotations reaches the number of full closures. The number of full closures may be determined in advance by adjustment on site.

In the above-described embodiment, the case where the instruction to open the movable feather 100 is input after the shutter curtain 20 is in the closed state has been described. However, the shutter curtain 20 is in the open state or the closing operation is performed. When an instruction to open the movable wing 100 is input in the middle, the control may be performed so that the movable wing 100 is continuously opened after the shutter curtain 20 is closed.
In the above-described embodiment, the case where the slat 10 is connected to the upper side and the lower side has been described. However, the present invention is not limited to this configuration. For example, if it is the structure connected so that each slat 10 may adjoin, a connection direction is not limited to an up-down direction.

  As another embodiment of the present invention, the present invention may be implemented by the configuration shown in the following supplementary notes. In that case, for example, the control unit 301 controls the motor 32 by detecting a load change in the first mode, and opens and closes the shutter curtain 20. Further, the control unit 301 controls the motor 32 by detecting the rotation speed in the second mode, and opens and closes the movable wing 100.
