Therefore, the versatility of the components of the electric switching device can be improved by using the existing components.

The present invention has various applications. The following applications can be combined as appropriate.
For example, the motor unit is driven at a first speed until the open / close body is lowered to a predetermined position, and when the open / close body is lowered to a predetermined position, the drive of the motor unit is stopped and the open / close body is Inertia descent, and after a predetermined time has elapsed, the control signal from the controller and the trigger signal may be generated again, and the motor unit may be driven at a second speed that is decelerated from the first speed. According to this configuration, when the opening and closing member reaches a predetermined height when it is lowered, the trigger signal temporarily stops the driving of the motor unit and makes it rotate in inertia, and the motor unit can be driven at a reduced speed after a predetermined elapsed time. Therefore, the deceleration effect can be realized more visually. Note that stopping the drive of the motor unit includes not only the state where the motor unit is not physically driven, but also the state where the motive power is not transmitted to the opening / closing member even if the motor unit is driven.

  Further, a motor control unit may be provided in the motor unit that receives a control signal from the controller and outputs a drive signal to the motor unit. According to this configuration, by providing the motor control unit in the motor unit, even in the motor unit without the motor control unit, the open / close control of various open / close members is realized without changing the connection means of the controller and the motor unit be able to.

  According to the present invention, a motorized switching device capable of improving the versatility of parts is provided. Other effects of the present invention will also be described in the embodiments for carrying out the invention described later.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same functional configuration will be assigned the same reference numerals and redundant description will be omitted.

First Embodiment
A first embodiment of the present invention will be described. First, the configuration of the electric switching device 100 according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a view schematically showing the overall configuration of the motored switching device 100. As shown in FIG. FIG. 2 is a block diagram for explaining the function of the motorized switching device 100. As shown in FIG.

  As shown in FIG. 1 and FIG. 2, the electric switching apparatus 100 mainly includes a switch 110, a controller 120, a motor unit 130, and an opening / closing member 140. Each component will be described in detail below.

(Switch 110)
The switch 110 is connected to the controller 120 as shown in FIGS. 1 and 2 and has a function as a command unit that transmits a command signal to the controller 120. As shown in FIG. 1, the switch 110 is provided with three buttons 110 u, 110 s, and 110 d. The raising button 110u is a button for giving an instruction to raise (UP) the opening / closing body 140, and "U" is displayed on the surface. The stop button 110 s is a button for giving an instruction to stop the operation of the opening and closing member 140 (STOP), and “S” is displayed on the surface. The lowering button 110d is a button for giving an instruction to lower the opening / closing member 140 (DOWN), and "D" is displayed on the surface.

(Controller 120)
As shown in FIGS. 1 and 2, the controller 120 is connected to the switch 110 and the motor unit 130, and is a functional unit that transmits a control signal to the motor unit 130. As shown in FIG. 2, the controller 120 mainly includes a central processing unit (CPU) 122 and a drive power supply unit 124. The central processing unit 122 receives the command from the switch 110 and the output from the encoder 132 in the motor unit 130 (such as the number of rotations of the motor unit 136), and controls the drive power supply unit 124. The drive power supply unit 124 is driven by an AC power supply of 100 V, and drives the A / D power supply unit 134 a in the motor unit 130 under the control of the central processing unit 122.

  The drive power supply unit 124 is connected to a CW line, a CCW line, and a COM line for transmitting the CW signal, the CCW signal, and the COM signal, as shown in FIG. These lines are connected to an A / D power supply unit 134 a in a motor unit 130 described later. Under the control of the central processing unit 122, the drive power supply unit 124 turns on / off (conductive / nonconductive) the CW line, the CCW line, and the COM line. The relationship between the CW line, the CCW line and the COM line, and the motor unit 130 will be described later.

(Motor unit 130)
As shown in FIGS. 1 and 2, the motor unit 130 is connected to the controller 120 and the opening / closing body 140, and is a functional unit for controlling the opening / closing body 140. As shown in FIG. 2, the motor unit 130 mainly includes an encoder 132, a motor control unit 134, and a motor unit 136. The encoder 132 is a functional unit that counts the number of rotations of the motor unit 136. The output of the encoder 132 is input to the central processing unit 122 in the controller 120. The motor control unit 134 is a functional unit that controls the motor unit 136. The motor unit 136 is a direct current motor (DC motor) driven by a direct current signal.

  As shown in FIG. 2, the motor control unit 134 mainly includes an A / D power supply unit 134 a and a central processing unit 134 b. The A / D power supply unit 134a is connected to the CW line, the CCW line, and the COM line described above. The A / D power supply unit 134 a converts the CW signal, the CCW signal, and the COM signal, which are AC signals from the drive power supply unit 124, into DC signals, and sends the DC signals to the motor unit 136. The central processing unit 134 b controls the A / D power supply unit 134 a.

The relationship between the input and output in the A / D power supply unit 134a is as follows.
When the CW line is turned on, a signal (+) for driving the motor unit 136 clockwise (in the direction in which the opening and closing member 140 is raised) is output.
When the CCW line is turned on, a signal (−) for driving the motor unit 136 counterclockwise (in the direction in which the opening and closing member 140 is lowered) is output.
The turning on of both the CW line and the CCW line generates a trigger signal, and the motor unit 136 is decelerated without changing its rotational direction.
When both the CW line and the CCW line are off (non-conduction), the motor unit 136 is not driven. At this time, as the motor unit 136 is not driven, the opening / closing body 140 descends by inertia.

  The motor unit 136 is connected to the opening and closing body 140, and opens and closes the opening and closing body 140 under the control of the motor control unit 134. As described above, when any one of the CW line and the CCW line becomes conductive and the control signal from the controller 120 is input, the motor unit 136 is driven in one direction. Then, when the opening and closing member 140 is in a predetermined state, both the CW line and the CCW line are conducted to generate a trigger signal, and the driving speed of the motor unit 136 is changed.

(Opening body 140)
The opening and closing body 140 is controlled to open and close by the drive of the motor unit 136 as shown in FIGS. 1 and 2. Specifically, the opening and closing body 140 is, for example, a shutter, a screen, or a blind.

  The configuration of the motorized opening and closing device 100 of the present embodiment has been described above. Next, the operation of the motorized opening and closing device 100 will be described with reference to FIGS. 3 to 8. The operation at the time of lowering of the opening and closing body 140 and the operation at the time of rising will be described in this order.

(Operation at the time of descent of opening and closing body 140)
First, the operation of lowering the opening / closing member 140 will be described with reference to FIGS. 3 to 5. FIG. 3 is a flow chart showing an operation at the time of lowering of the opening and closing member 140. FIG. 4 is a view showing an operation at the time of lowering of the opening and closing member 140. As shown in FIG. FIG. 5 is a view showing the relationship between the movement amount (falling height) and the number of rotations when the opening and closing member 140 is lowered.

  The opening and closing body 140 will be described as being above the predetermined height. When the lowering button 110 d of the switch 110 is operated, the controller 120 performs control for lowering the opening / closing body 140. The controller 120 conducts the CW line as shown in FIG. 4A (step S110). When the CW line becomes conductive and the control signal from the controller 120 is input, the motor unit 136 is driven in one direction (see the solid arrow in the clockwise direction in FIG. 4A), and the open / close member 140 is lowered (step S120).

The rotation of the motor unit 136 is counted by the encoder 132. The controller 120 can know the height of the opening / closing body 140 by the count of the encoder 132 being input. From the upper limit position to the predetermined height h _d from the upper limit position, as shown by symbol a in FIG. 5, the rotation number of the motor unit 136 is constant.

Then, the controller 120 performs control to change the driving speed of the motor unit 136 when the opening and closing member 140 reaches the predetermined height h _d . That is, when the opening / closing member 140 reaches a predetermined height h _d , as shown in FIG. 4B, both the CW line and the CCW line are conducted to generate a trigger signal (step S130). The driving speed of the motor unit 136 is reduced (see the broken arrow in the clockwise direction in FIG. 4B) (step S140).

From the predetermined height h _d to the lower limit position h _{dx of the} opening / closing body 140, as shown by symbol b in FIG. 5, the number of rotations of the motor portion 136 gradually decreases. Then, when the opening and closing member 140 reaches the predetermined lower limit position (step S150), the operation is stopped (step S160).

(Operation when the opening and closing body 140 is lifted)
Next, the operation at the time of lifting of the opening and closing member 140 will be described with reference to FIGS. FIG. 6 is a flow chart showing the operation when the opening and closing member 140 is lifted. FIG. 7 is a view showing an operation when the opening and closing member 140 is lifted. FIG. 8 is a view showing the relationship between the movement amount (rise height) and the number of rotations when the opening and closing member 140 is raised.

  The opening and closing body 140 will be described as being below the predetermined height. When the lift button 110 u of the switch 110 is operated, the controller 120 performs control to raise the opening / closing body 140. The controller 120 conducts the CCW line as shown in FIG. 7A (step S210). When the CCW line becomes conductive and the control signal from the controller 120 is input, the motor unit 136 is driven in one direction (refer to the solid-line arrow counterclockwise in FIG. 7A), and the cover 140 is raised ( Step S220).

From the lower limit position to the predetermined height h _u from the lower limit position, the rotational speed of the motor unit 136 is constant, as indicated by symbol a in FIG.

Then, the controller 120 performs control to change the driving speed of the motor unit 136 when the opening and closing member 140 reaches the predetermined height h _u . That is, when the opening / closing member 140 reaches a predetermined height h _u , as shown in FIG. 7B, both the CW line and the CCW line are conducted to generate a trigger signal (step S230). The driving speed of the motor unit 136 is reduced (refer to the broken arrow in the counterclockwise direction in FIG. 7B) (step S240).

From the predetermined height h _u to the upper limit position h _{ux of the} opening / closing body 140, the rotational speed of the motor portion 136 gradually decreases as indicated by symbol b in FIG. Then, when the opening / closing member 140 reaches the predetermined upper limit position (step S250), the opening / closing body 140 stops the operation (step S260).

(Effects of the first embodiment)
As described above, according to the present embodiment, when any one of the CW line and the CCW line is conductive, the trigger signal is generated when the other line is simultaneously conductive, and the driving speed of the motor unit 136 is generated. Will be able to change. For example, when the opening and closing member 140 is moving up and down, the raising and lowering speed is decelerated from a predetermined position by a trigger signal, and it can be opened and closed slowly to the open / close limit position to reduce operation noise. As described above, it is possible to realize the change of the driving speed of the motor unit 136 while using the existing switch 110 and the controller 120. Therefore, the versatility of the components of the electric switching device 100 can be improved by using the existing components.

Second Embodiment
A second embodiment of the present invention will be described mainly with reference to FIG. 9 and FIG. The present embodiment is different from the first embodiment in the control of the controller 120. In the present embodiment, differences from the above embodiment will be mainly described with reference to FIGS. 1, 2 and 4 as appropriate. About the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  The control of the controller 120 of the present embodiment will be described mainly with reference to FIGS. 9 and 10. FIG. 9 is a flow chart showing an operation at the time of lowering of the opening and closing member 140. FIG. 10 is a view showing the relationship between the movement amount (falling height) when the opening / closing body 140 is lowered and the rotational speed of the motor unit 136. As shown in FIG. The broken lines in FIG. 10 are for comparison with the first embodiment (FIG. 5).

  The opening and closing body 140 will be described as being above the predetermined height. When the lowering button 110 d of the switch 110 is operated, the controller 120 performs control for lowering the opening / closing body 140. The controller 120 conducts the CW line (step S310). When the CW line conducts and the control signal from the controller 220 is input to the motor unit 136, the motor unit 136 is driven in one direction, and the open / close member 140 is lowered (step S320).

As indicated by symbol a in FIG. 10, the rotation number of the motor unit 136 is constant from when the opening / closing member 140 starts to descend until it reaches the predetermined height h _d .

Then, the controller 120 performs control to change the driving speed of the motor unit 136 when the opening and closing member 140 reaches the predetermined height h _d . That is, when the opening / closing member 140 reaches the predetermined height h _d , both the CW line and the CCW line are conducted to generate a trigger signal (step S330), and the driving speed of the motor unit 136 is reduced.

  When 0.1 seconds elapse, the CW line and the CCW line are disconnected. At this time, the opening / closing body 140 is lowered by the inertia operation (step S340, symbol b in FIG. 10). Thereafter, when 0.4 seconds have elapsed, the CW line is turned on. As a result, the opening / closing member 140 is lowered again by the motor unit 136 (step S350, symbol c in FIG. 10). Further, after that, when 0.1 second elapses, both the CW line and the CCW line are made conductive to re-generate the trigger signal to reduce the driving speed of the motor unit 136 (step S360, sign of FIG. 10) d).

  Then, when the opening and closing member 140 reaches the predetermined lower limit position (step S370), the operation is stopped (step S380).

(Effect of the second embodiment)
As described above, according to the present embodiment, when the opening and closing member 140 reaches a predetermined height at the time of descent, the trigger signal temporarily stops the driving of the motor unit 136 and rotates in inertia, and the speed decelerated after a predetermined elapsed time Since the motor unit can be driven at the same time, the deceleration effect can be realized more visually. The above-described times (0.1 seconds and 0.4 seconds) are merely examples, and can be set as appropriate in consideration of visual effects and the like.

  In the present embodiment, the operation at the time of lowering of the opening / closing body 140 has been described, but the operation can be similarly performed at the time of rising of the opening / closing body 140. Further, the configuration or operation which has not been described in the present embodiment can be substantially the same as the configuration or operation described in the first embodiment.
