Description

  The present invention belongs to the technical field of ventilation and daylighting type electric shutter devices built in windows and doorways of houses.

  Generally, in an electric shutter device configured such that a shutter curtain opens and closes an opening by driving an opening / closing device in accordance with operation of an operation tool, the shutter curtain is connected to a plurality of slats in a series, and the shutter curtain By opening and closing the switch at the lower limit position where the lowermost slat abuts (adjacent to) the floor, a gap is formed between each adjacent slat so that ventilation and lighting in the opening can be prevented. There are some which are configured to change into a gap forming posture which can be changed and a closed posture where the gap is eliminated. In this case, by adjusting the posture in the gap formation posture and appropriately changing the size of the gap, the amount of light collected and the amount of ventilation in the opening can be changed. Then, when adjusting the shutter curtain posture by operating the operation switch, for example, immediately after the shutter curtain that has been once closed by operating the closing switch is operated to open by operating the opening switch. By operating the stop switch, a gap forming posture was set. For this reason, in order to finely adjust the optimum gap formation posture, the switches for opening, stopping, and closing must be handled as inching operations, which is complicated and in this case Since there is a time lag between the actual operation and the operation of the shutter curtain, there is a problem that the operation is difficult, there is no reproducibility, the posture adjustment is difficult, and it is troublesome. Therefore, in addition to the switch for opening and closing the shutter curtain in the operating tool, there is also a switch that can be adjusted easily by operating using the switch for adjustment, but in this case, in this case, Since a general-purpose operation tool cannot be used, there is a problem that costs increase.

As a measure for improvement, a general-purpose operation tool, that is, an operation tool provided only with an opening / closing / closing switch for opening and closing the shutter curtain is used and stored in advance in a memory as a predetermined switch operation is performed. What has been made possible to achieve the desired action posture is proposed, and thereby, the operation to make the gap forming posture can be performed easily and easily.

  However, in the conventional device, a plurality of gap forming postures having different gap amounts are stored in the control unit, and an operation for operating the closing switch for a predetermined time set in advance for these different gap forming postures. A configuration in which the shutter curtain is set to the desired gap forming posture by setting the number of times and selecting and operating the number of closing switch operations corresponding to the desired gap forming posture as much as possible when closing the shutter curtain. It has become. As described above, the conventional configuration is configured to specify the gap formation postures having different gap amounts by the number of times the operation switch is operated for a predetermined time. In this case, the number of types of operation of the operation switch is increased. There is a limit, and it is not possible to increase the types of gap forming postures that can be stored in advance. Further, if the number of tentatives and types is increased, the number of switch operations to be performed in a short period of time increases, resulting in a problem that the operation becomes complicated and difficult. For this reason, the degree of freedom of adjustment in the gap forming posture is narrowed, and there is a problem that it may not be possible to obtain an optimal gap forming posture that suits the use conditions depending on the season. Also, in this case, it is possible to obtain an optimal gap formation posture that matches the use conditions by changing the stored gap formation posture, but since it is necessary to re-store the desired gap formation posture one by one, There is also a problem that the memory operation is troublesome and troublesome, and there are problems to be solved by the present invention.

According to the invention of claim 4, it is possible to provide a more convenient ventilation and lighting type electric shutter device.

Next, embodiments of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a ventilation / lighting type electric shutter device installed in an opening corresponding to a window of a house, and a shutter curtain 2 constituting the electric shutter device 1 is configured by using a plurality of slats 3. However, each of the slats 3 is swingably disposed on a telescopic pantograph-like link body (not shown) provided in a pair of guide rails 4 disposed on the left and right sides of the opening. Are respectively connected to the operating pieces.
A head case 5 is arranged above the opening, and a drive shaft 6 that is long in the left-right direction is rotatably mounted in the head case 5, at both left and right ends of the drive shaft 6. The drive sprockets 6a are integrally fitted and fixed in positions facing the pair of guide rails 4 respectively. On the other hand, a driven sprocket (not shown) is rotatably mounted at the lower end portion of the guide rail 4, and an endless chain (not shown) is suspended between the driven sprocket and the drive sprocket 6a. The chain is configured to be connected to the lower end portion of the link body to which each slat 3 is connected.

The drive shaft 6 is set so as to rotate forward and backward in accordance with forward / reverse driving of the opening / closing machine 7, and the forward / reverse rotation of the drive shaft 6 causes the left and right driven sprockets 6 a to rotate integrally, and the chain is driven to drive 6a and the driven sprocket are displaced in the vertical direction, and the link body expands and contracts while being guided by the guide rail 4, and the slat 3 connected to the link body is moved up and down integrally (opening and closing operation). Is set to let At this time, each slat 3 of the shutter curtain 2 has a maximum gap as shown in the upper part of FIG. 2A and the slat surface of each slat 3 in the horizontal direction, as indicated by the alternate long and short dash line in FIG. The shutter curtain 2 is set so as to move up and down in a first gap forming posture, and the shutter curtain 2 is opened by being housed in the head case 5 in a state where the slats 3 facing in the horizontal direction are stacked. It is set to a fully open posture that opens the part. Then, when the drive shaft 6 is driven to be closed from this state, the slats 3 maintaining the horizontal posture are sequentially lowered from the lower side in accordance with the extension operation of the link body that is forcibly moved down by the chain. In a state where a gap is formed between them, the lowermost slat 3 is set to descend until reaching the lower limit position close to the floor surface, and the drive shaft 6 is further driven in the state where the lower limit position is reached. As a result, each slat 3 swings as the operating piece swings relative to the link body, and the second gap forming posture shown by a thin line and the third gap forming posture shown by a two-dot chain line in FIG. Via, the adjacent slats 3 are parallel to each other in the vertical direction to close the gap between the slats 3 (fully closed posture of the shutter curtain 2), and the opening is fully closed It is set so as to state. By the way, in the opening operation of the shutter curtain 2, the operating piece swings and the slats 3 in the closing posture are changed to the first gap forming posture that faces the horizontal direction via the third and second gap forming postures, and then the link. When the body starts to shrink, it starts to move upward, and the slat 3 on the lower end side moves upward while being sequentially stacked on the upper slat, and is set to a fully open posture that opens the opening. Yes.
In the gap formation posture of the shutter curtain 2, the opening is ventilated and daylighted. In the gap formation posture, the swing angle of each slat 3 is adjusted by adjusting the swing amount of the operating piece accompanying the rotation of the drive shaft 6. Adjustment (posture adjustment) is performed, and thereby, the air flow rate and the amount of light collected are set as appropriate, but these basic configurations are all conventional.

An operation switch 8 is an operation tool for opening and closing the shutter curtain 2. The operation switch 8 is provided on the indoor side of the opening, and an opening operation switch PBU for opening and closing the shutter curtain 2. A stop operation switch PBS and a closing operation switch PBD are provided.
On the other hand, 9 is a control unit connected to the switch 7 to control the opening / closing of the switch 7, and the control unit 9 includes a CPU. The control unit 9 is connected to the operation switch 8, and the upper limit position detection switch LSU that switches the shutter curtain 2 when the shutter curtain 2 is opened to the fully open posture, and the lowermost slat of the shutter curtain 2. 3 is a lower limit position detection switch LSD that detects the change of position to the closed position by contacting the floor, and an obstacle that is switched as the shutter curtain 1 comes into contact with the obstacle during the closing operation. Necessary switches such as the detection switch 10 are appropriately connected. As the switches PBU, PBS, PBD, LSU, LSD, 10 and the like are operated or switched, the control unit 9 has a corresponding opening operation signal, stop operation signal, closing operation signal, upper limit position. The detection signal, the lower limit position detection signal, the obstacle detection signal, and the like are set to be input.

Then, in the normal opening / closing control mode, the control unit 9 opens to the switch 7 in response to the input signals from the switches PBU, PBS, PBD, LSU, LSD 10 and the like. By outputting any one of a drive command, a drive stop command, and a closing drive command, the opening / closing control is performed to open / close the shutter curtain 1 by driving the switch 7 to open / close.
The control unit 9 is provided with posture adjustment control means 9a. When the shutter curtain 2 reaches the lower limit position and is in the closed posture, a mode switching operation is performed, so that the posture adjustment mode is set. It is set so that it can be switched. When switched to the posture adjustment mode, the control unit 9 is set to perform posture adjustment for appropriately changing the shutter curtain 2 to a gap forming posture based on the switch operation of the operation switch 8. In this posture adjustment mode, the control unit 9 drives the opening / closing device 7 to be opened during the first timer period in response to one operation (opening operation) of the opening operation switch PBU. With the operation (closing operation) of the switch PBD, the switch 7 is set to be driven to close during the second timer time. In any operation, the first and first operations are performed regardless of the operation time. It is set to drive for two timers.
Here, in the posture adjustment mode, for example, in a state where the opening operation is performed and the switch 7 is driven to open, even if the operation switch 8 is operated, the control unit 9 does not accept a signal due to the operation. Thus, the adjustment operation can be performed while checking the adjustment of the gap formation posture, and the posture can be adjusted smoothly while being reliable.

Further, the control unit 9 is provided with a gap formation posture storage means 9b. When the predetermined gap formation posture is set in the posture adjustment mode, the previous stop position (stop) which is the set gap formation posture is set. State) is stored, and when switching to the next posture adjustment mode, the opening / closing machine 7 is driven to set the shutter curtain 2 to the previous gap formation posture (positioned at the stop position). Thus, when the mode is switched to the posture adjustment mode, the posture may be adjusted based on the previous gap formation posture, and the desired gap formation posture can be adjusted with higher operability.
Reference numerals 11 and 12 are indicator lights and buzzers provided on the indoor side of the opening, and the controller 9 is set to light up and sound based on a command from the controller 9 by switching to the posture adjustment mode. Has been.

Here, in the present embodiment, the mode switching operation is performed by pressing the stop operation switch PBS of the operation switch 8 for a preset time (for example, two seconds) or more in a state where the shutter curtain 2 is in the closed posture. Is set to be.
In the present embodiment, the time required until the shutter curtain 2 (each slat 3) changes from the closed position to the first gap forming position where the maximum gap is formed, that is, the shutter curtain 2 is at the lower limit position. The time required to reach the closed posture is set to approximately 0.9 seconds. Then, the first timer time for the opening and closing operation of the opening / closing device 7 by performing the opening operation once in the posture adjustment mode is shorter than the time required for changing from the closed posture to the first gap forming posture, It is set to 0.3 seconds corresponding to 1/3 of the required time. In addition, the second timer time during which the switch 7 is driven to close by performing a single closing operation is shorter than the first timer time, and is set to 0.1 second in the present embodiment.
By setting in this way, in the case where the second gap forming posture shown in FIG. 2B is a posture realized by opening and closing the switch 7 from the closed posture for 0.7 seconds, for example, an opening operation is performed. Is performed three times (0.9 second opening drive) to obtain the first gap forming posture, and then the second gap forming posture can be obtained by performing the closing operation twice (0.2 second closing drive). . In the case where the third gap forming posture shown in FIG. 2B is a posture realized by driving the opening / closing device 7 to open for 0.5 seconds from the closed posture, the opening operation is performed twice (0.6 seconds). The third gap forming posture can be obtained by performing the closing operation once (0.1 second closing driving) after performing the opening driving. Thus, in the posture adjustment mode, by repeatedly repeating the opening operation and the closing operation, the slats 3 can be oscillated and displaced corresponding to the opening operation of the opening / closing device 7 for 0.1 seconds, and the gap The posture adjustment in the forming posture can be performed by simple and easy operation, and the adjustment can be made to change greatly in the opening operation, and the adjustment can be made to change small in the closing operation. Thus, it is configured so as to be able to surely adjust.

Next, the opening / closing control state of the shutter curtain 2 by the control unit 9 and an example of the control procedure in the posture adjustment control means will be described based on the block diagram of FIG. 3, the flowcharts of FIGS. 4, 5 and the timing charts of FIGS. explain.
First, the flowchart of FIG. 4 will be described. When the preset initial setting is made and the switching control mode is set, the control unit 9 determines whether or not the closing operation switch PBD is operated and there is an input of a closing operation signal. A closing drive command is output, and the closing operation of the shutter curtain 2 is started. Subsequently, the control unit 9 determines whether or not a stop operation signal is input in the process of the closing operation, and when it is determined that there is a stop operation signal input, the shutter curtain 2 stops in a halfway open state. The control unit 9 is set to output a drive stop command and return (return) to the initial state.

  On the other hand, when it is determined that there is no stop operation signal input, the control unit 9 determines whether there is an obstacle detection signal input, and when it is determined that there is an obstacle detection signal input, the obstacle detection is performed. It is set to control. The obstacle detection control is set to perform an opening operation (touch-up) for a predetermined time after the shutter curtain 2 has been urgently stopped. When an obstacle detection signal is input, the control unit 9 performs a predetermined operation of the shutter curtain 2 and then performs a predetermined operation (return operation) to return to the initial state. Is set.

Further, when it is determined that no obstacle detection signal is input, the control unit 9 determines whether there is a lower limit position detection signal input, and when there is no lower limit position detection signal input, outputs a closing drive command. Continuing, it is determined whether or not the lowermost position detection signal has been input when the lowermost slat 3 of the shutter curtain 2 comes into contact with the floor and the shutter curtain 2 is in the closed posture. When it is determined that the lower limit position detection signal has been input, the control unit 9 is set to output a drive stop command.
In the open / close control mode, when it is determined that the closing operation signal is not input, it is determined whether or not the opening operation signal is input, and when the opening operation signal is input, the opening drive command is output. Then, the shutter curtain 2 is opened, but the opening control has a conventional configuration and will not be described in detail.

In the state where the shutter curtain 2 is changed to the closed posture, the control unit 9 inputs a stop operation signal during the N1 timer time (2 seconds in the present embodiment) which is a predetermined time of the present invention as the mode switching operation. If there is no input, the initial state is restored. If there is an input, the posture adjustment mode is set to perform posture adjustment control.
When shifting to the posture adjustment control, as shown in the flowchart of FIG. 5, the control unit 9 sets N2 timer set to a preset N2 timer time (maximum time for posture adjustment, for example, 60 seconds). While setting the timer, the indicator lamp 11 is turned on and the buzzer 12 is sounded to notify the user that the posture adjustment mode has been entered. Further, when the previous gap formation posture is stored in memory, the control unit 9 outputs a drive command to the switch so that the previous gap formation posture is obtained, and sets the shutter curtain 2 to the previous gap formation posture. Subsequently, the control unit 9 waits for an operation signal from the operation switch 8. In the standby state, when the open operation switch PBU is operated and an open operation signal is input, the N3 timer time (this implementation) In the embodiment, although it is set to 2 seconds like the N1 timer time, it is not necessarily limited to the input of the stop operation signal. (For example, the signal may be input by simultaneously pressing the stop operation switch and the release operation switch), and the N4 timer set within the N2 timer time or a preset N4 timer time described later is set. In the case where the current time is within the N4 timer time, the preset N5 timer time (the first timer time, which is 0.3 in this embodiment) Set the N5 timer set in between), and is set to output the drive open command during the said N5 timer time. At this time, if the posture adjustment operation has already been performed and the N4 timer is operating, the control unit 9 cancels the set N4 timer, outputs the opening drive command, and then restarts the N4 timer. Set to return to the operation signal standby state.

  On the other hand, when the closing operation switch PBD is operated and the closing operation signal is input in the standby state, there is no input of the stop operation signal for the N3 timer time and the N4 timer is operating within the N2 timer time. In this case, on the condition that it is within the N4 timer time, the N6 timer set to the preset N6 timer time (second timer time, which is 0.1 second in the present embodiment) is set, The closing drive command is set to be output during the N6 timer time. At this time, if the posture adjustment operation has already been performed and the N4 timer is in operation, the set N4 timer is canceled, the closing drive command is output, the N4 timer is set again, and the operation signal Return to standby state.

Here, the control unit 9 sets the N4 timer when an open or close drive command is output during the N5 or N6 timer time, and the N4 timer is set between the switch operation and the switch operation for posture adjustment. Is set to 10 seconds in the present embodiment. Thus, as will be described later, when the time between the switch operations becomes longer in the posture adjustment mode, the normal opening / closing control mode is set (returned). For this reason, if the switch operation is performed for the first time in the posture adjustment mode, the control unit 9 does not determine whether it is within the N4 timer time. In this embodiment, the N4 timer is set to be set when the operation signal from the operation switch 8 disappears, as shown in the timing chart of FIG. In this case, the operability is improved.
Then, as in the present embodiment, by controlling to provide the N4 timer, it is possible to quickly return to the normal opening / closing control mode after making necessary adjustments when changing to the gap forming posture. There is an advantage that you can.

As described above, in the state of shifting to the posture adjustment mode, the posture adjustment can be performed by repeatedly operating the operation switch 8 during the N2 timer time. When the stop operation signal is input during the N3 timer time, the control unit 9 determines that the attitude adjustment mode has ended, and releases the N4 timer together with the N2 timer if the N4 timer is operating. On the other hand, the indicator lamp 11 is turned off, the buzzer 12 is stopped, and the current stop position (gap formation posture) of the shutter curtain 2 is stored (memory), and then set to the normal opening / closing control mode. (Refer to the timing chart in FIG. 6A).
Further, in the posture adjustment mode, if no switch operation is performed during the N4 timer time after the operation by the opening or closing operation switch PBU or PBD within the N2 timer time, the posture adjustment mode is set as described above. It is determined that the timer has ended, the N2 timer is released, the indicator lamp 11 is turned off, the buzzer 12 is stopped, and the current stop position (gap formation posture) of the shutter curtain 2 is stored, and then the normal opening / closing control The mode is set to shift to the mode (see the timing chart in FIG. 7A).
Accordingly, in any case, after the posture adjustment, the normal opening / closing control mode can be promptly shifted.

On the other hand, when the N2 timer time has elapsed after entering the posture adjustment mode, it is determined that the posture adjustment mode has ended, and when the N4 timer is operating, the N4 timer is canceled, while the indicator lamp 11 The light is turned off, the sounding of the buzzer 12 is stopped, and the current stop position of the shutter curtain 2 is memorized, and then it is set to shift to the normal opening / closing control mode (see the timing chart in FIG. 6B).
As a result, after switching to the posture adjustment mode and adjusting the posture, even if the forgetting operation of the stop operation switch PBS for the N3 timer time is forgotten, it is possible to surely shift to the normal opening / closing control mode. Even when the operation switch 8 is operated to cause the shutter curtain 2 to perform a normal opening / closing operation, as in the case where the portion 9 remains in the posture adjustment mode, the operation of the shutter curtain 2 adjusts the posture. Thus, it is possible to solve the problem that the operation becomes different from the intention of the operator. Furthermore, even when the stop operation switch PBS is broken and becomes inoperable for some reason after switching to the posture adjustment mode, it is possible to automatically shift to the normal opening / closing control mode.

In this embodiment, the transition from the posture adjustment mode to the normal opening / closing control mode is performed by inputting an obstacle detection signal to the control unit 9 or from a temperature abnormality detection switch that detects a temperature abnormality of the switch 7. It is configured to shift even when there is a so-called shutter abnormality, such as an input of a detection signal. For example, in the case of shifting from the posture adjustment mode with the input of an obstacle detection signal, the timing of FIG. As shown in the chart, the indicator lamp 11 is turned off and the buzzer 12 is turned off, and immediately set to shift from the posture adjustment mode to the normal opening / closing control mode.
Further, as a standby mode in a state where the shutter curtain 2 is in a closed posture, it is configured to wait for a switching operation to the posture adjustment mode by the stop operation switch PBS, a timer time in the standby mode is set in advance, If there is no switching operation during the timer period, the standby mode may be automatically shifted to the normal opening / closing control mode.

  As described above, in the posture adjustment mode, regardless of the operation time of the opening operation switch PBU and the closing operation switch PBD, if the opening operation switch PBU is operated, the N5 timer time is opened and the closing operation switch is operated. If the PBD is operated, the N6 timer time is set to be closed, and the state is shown in the timing charts of FIGS. 6 (A), 6 (B), and 7 (A). As a result, the adjustment of the slat 3 to a delicate swing angle can be performed easily, reliably and with good reproducibility.

  In the present embodiment configured as described, each slat 3 swings and changes into a gap forming posture and a closed posture by driving the opening / closing device 7 with the shutter curtain 2 reaching the lower limit position. The posture adjustment of the shutter curtain 2 in the gap formation posture can be performed by operating the existing operation switch 8 without providing a separate adjustment switch. In this case, the operation switch 8 is driven to open or close for a preset N5 timer time or N6 timer time, regardless of the pressing operation of the opening operation switch PBU or the closing operation switch PBD. In other words, variations in gap formation postures can be made abundant. In addition, quick operation is not required, and accurate fine adjustment can be performed at any time. Good ventilation and daylighting type electric shutter device 1 can be provided.

  As described above, when the present invention has been implemented, the mode is switched to the posture adjustment mode for adjusting the posture in the gap forming posture based on the operation of the operation switch 8, but when the posture adjustment mode is switched to In addition, the N5 (first) timer time for opening driving by operating the opening operation switch PBU (opening operation) is longer than the driving time required for the shutter curtain 2 to change between the closed position and the first gap position. Is set to a time longer than the N6 (second) timer time of the closing drive by the operation (closing operation) of the closing operation switch PBD, so that the closing posture can be obtained by appropriately combining the opening operation and the closing operation. Can be quickly changed to a gap forming posture, and fine posture adjustment can be realized with certainty.

  In addition, in this case, the gap formation posture storage means is provided, the gap formation posture set in the posture adjustment mode is stored, and when the next posture adjustment mode is switched, the previous gap is automatically set. Because of the formation posture, the optimum gap formation posture can be obtained as it is depending on the conditions, and the air-operated and daylighting type electric shutter device 1 that is more convenient to use can be obtained.

Of course, the present invention is not limited to the above embodiment, and the mode switching operation for switching the control unit to the posture adjustment mode is not necessarily an operation using the operation tool. As shown in the timing chart of), it is possible to automatically switch to the posture adjustment mode by switching to the posture adjustment mode when the shutter curtain reaches the lower limit position and changes to the closed posture. In this case, after the shutter curtain is closed, if any switch operation is performed, the adjusted gap formation posture can be obtained, and if no operation is performed, the previous gap formation posture can be automatically set. Can be made more operable.
In addition, as in the first embodiment, a plurality of conditions for shifting from the posture adjustment mode to the normal opening / closing control mode can be set, but either one is selected according to the use environment. One or two can be selected as appropriate.
