Description

  The present invention relates to an opening / closing device having an opening / closing body operating position setting function and an opening / closing body operating position setting method.

  The opening / closing device includes a driving means for driving an opening / closing body such as a shutter curtain in an opening direction and a closing direction, and an operation position detection means for detecting an operation position of the opening / closing body by detecting an operation of the driving means. There has been known one provided with a control unit for controlling the automatic stop of the driving means in accordance with the operating position of the opened / closed body. An opening / closing apparatus provided with such a control unit recognizes the origin position for operating the opening / closing body, and uses the origin position as the origin to set the fully closed position and the operating position of the opening / closing body detected by the operation position detecting means. The fully open position and the intermediate position are made to correspond.

  The one described in Patent Document 1 below sets the origin position (full open position) of the opening / closing body, and detects the operating position of the opening / closing body by counting the number of encoder pulses of the drive means using this origin position as the origin. In addition, the opening / closing body is automatically stopped at the fully open position and the fully closed position. The origin position and the fully closed position of the opening / closing body are set by a setting operation after the stop operation of the opening / closing body by a remote controller.

  The thing of the following patent document 2 is the same as that of the above-mentioned patent document 1, and counts the pulse number of the encoder pulse of a drive means from the set origin position (fully opened position) as an origin, The operating position is detected, and the opening / closing body is automatically stopped at the fully open position, the fully closed position, and further at the intermediate position. Further, the origin position, fully closed position, and intermediate position of the opening / closing body are set by the setting operation of the remote controller as in the above-mentioned Patent Document 1, but at this time, the setting operation of each position is performed. The user is informed of the fact that it has been performed effectively by sound or light from a sound generator, LED, or the like equipped in the remote control.

  These positions in Patent Documents 1 and 2 are set by the normal opening / closing operation of the remote control at a position that the user recognizes as a fully open position, a fully closed position, and an intermediate position while opening / closing the opening / closing body. A numerical value at each position is set by performing a setting operation using a different operation.

Has been. That is, the end of setting of the fully open position P1 and the fully closed position P2 is notified by the operation sound of the braking portion 2B that operates at the end of setting of the fully open position P1 and the fully closed position P2.

  Further, the opening / closing device 1 is provided with a photoelectric sensor 11 that detects an obstacle in the opening 1A. The photoelectric sensor 11 is controlled to output an obstacle detection signal when an obstacle is detected, and control for stopping the closing operation of the opening / closing body 10 of the control unit 7 based on the obstacle detection signal. Is done. The sensor for detecting the obstacle is not limited to the photoelectric sensor 11, and for example, a contact sensor, a weight sensor, or the like may be used.

  In this embodiment, the opening / closing body opening / closing direction is the vertical direction. Further, the fully open position P1 is set to a position where the lower end portion 10A of the opening / closing body 10 corresponds to the lower end portion 200 of the storage portion 100, and the fully closed position P2 is set to the floor surface FL where the lower end portion 10A of the opening / closing body 10 contacts. The corresponding position is set, and the origin position P3 is set between the fully open position P1 and the fully closed position P2. The origin position P3 is set in the vicinity of the fully open position P1 (for example, a range of 50 mm to 150 mm downward from the fully open position P1).

  The opening / closing body 10 is a sheet-like body made of a flexible synthetic resin material. The opening / closing body 10 is mounted on a winding shaft 101 that is rotatably supported in the storage unit 100 so as to be wound and driven. The winding shaft 101 is supported with its axial direction parallel to the opening / closing body width direction.

  The opening / closing machine 3 is supported so that the drive shaft 21 is parallel to the axial direction (opening / closing body width direction) of the take-up shaft 101, and the drive rotation of the drive shaft 21 is made up of a gear train, a chain, a belt, and the like.

  The operation unit 4 is a remote controller that remotely controls the opening / closing operation of the opening / closing body 10 by radio, and includes an opening operation unit 40, a closing operation unit 41, and a stop operation unit 42. The operation unit 4 outputs an opening / closing operation signal, an operation position setting operation signal, an operation switching signal, and an origin correction operation signal by performing predetermined operations on the opening operation unit 40, the closing operation unit 41, and the stop operation unit 42. It has become.

  An example of the aforementioned predetermined operation in the operation unit 4 is shown in Table 1 below. The operation unit 4 is not limited to a wireless remote controller, and may be a wired type. Further, the operation settings for outputting the operation position setting signal and the origin correction start signal described above are not limited to the operation settings illustrated in Table 1, and the opening operation unit 40, the closing operation unit 41, and the stop operation unit. In addition to 42, an operation unit for outputting an operation position setting operation signal and an operation unit for outputting an origin correction signal may be provided (not shown).

  The origin detection unit 5 includes a rotary shaft 50 supported so as to be parallel to the axial direction (opening / closing body width direction) of the winding shaft 101, and a switch unit 51 that performs an ON / OFF operation in accordance with the rotation of the rotary shaft 50.

Such an origin detection unit 5 turns on the switch unit 51 when the lower end of the opening / closing body 10 matches the origin position P3 during the opening / closing operation of the opening / closing body 10 performed by the rotation of the winding shaft 101. When the switch 51 is turned on, the origin is detected and an origin detection signal is output.

  FIG. 2 is a configuration diagram of the switch 3. As the opening / closing machine 3, for example, one having a known structure disclosed in Japanese Utility Model Laid-Open No. 1-118084 can be used. Hereinafter, although the basic structure of this switch 3 is demonstrated, the switch 3 of this invention is not restricted to the thing of the form illustrated.

  The drive unit 2A of this embodiment is a known permanent magnet synchronous motor having an electromagnetic brake function. In addition, the drive unit 2A is not limited to the illustrated permanent magnet synchronous motor, and an excitation synchronous motor including an electromagnetic brake such as an electromagnet synchronous motor can be used.

  The brake unit 2B includes a brake member 22 that rotates in the same body as the drive shaft 21, a brake shaft 23 that is disposed coaxially with the drive shaft 21, and a movable brake member 24 that is fixed to the brake shaft 23 and contacts and separates from the brake member 22. And a coil spring 25 that urges the movable braking member 24 toward the braking member 22, and an electromagnetic solenoid 26 that separates the movable braking member 24 from the braking member 22 against the urging force of the coil spring 25 by excitation. Yes.

  The electromagnetic solenoid 26 is energized by the control unit 7 when the fully open position P1 and the fully closed position P2 of the opening / closing body 10 are set, and the movable brake member 24 is separated from the brake member 22, and the excitation is released after the separation is completed. The movable braking member 24 is controlled to come into contact with the braking member 22. That is, when the electromagnetic solenoid 26 is de-energized under the control of the control unit 7 and the movable braking member 24 is brought into contact with the braking member 22 by the urging force of the coil spring 25, the contact sound is generated from the fully open position P1 and the fully closed position described above. This is an operation sound to notify the end of the setting of the position P2. This operation sound may be generated when the movable braking member 24 is separated from the braking member 22 by the excited electromagnetic solenoid 26.

  The brake unit 2B is not used for maintaining the stop state in the normal opening / closing operation of the opening / closing body 10 but for generating an operation sound for notifying the end of the setting, and the driving unit 2A by a power failure. Even when the electromagnetic brake is no longer functioning, it is an existing one for braking so that the drive shaft 21 does not rotate due to the weight of the opening / closing body 10. Therefore, when the opening / closing body 10 is stopped except when the operation sound for notifying the end of the setting is generated, the movable braking member 24 is in a braking state in contact with the braking member 22.

  3 and 4 are schematic views of the drive unit 2A. The drive unit 2A alternately arranges a plurality of permanent magnets M in the N pole and the S pole over the entire circumference of the drive shaft 21, and the three stators U, V, W is a three-phase structure in which W are arranged at an angle of 120 degrees in the circumferential direction of the drive shaft 21. Such a drive unit 2A causes the stators U, V, and W to turn on and off a semiconductor switch (not shown) so that the magnetic poles of the stators U, V, and W are the same as the facing permanent magnet M. The drive shaft 21 is rotated by causing a current to flow while generating a rotating magnetic field between the permanent magnet M and the stators U, V, and W.

  The drive unit 2A drives the open / close body 10 to open / close across the fully open position P1 and the fully closed position P2 within the open / close operation range of the open / close body 10, and the open / close body 10 is fully open position P1 and fully closed position. It is controlled to stop driving when it reaches P2. In addition, when the opening / closing body 10 that performs the opening / closing operation reaches near the fully open position P1 and close to the fully closed position P2, the driving speed is controlled to decrease.

  Further, when the drive is stopped, the drive unit 2A causes the stator U and V to turn on the semiconductor switch so that current flows through the stator U and V so that the magnetic poles of the stators U and V are different from the facing permanent magnet M. As a result, the drive shaft 21 is braked.

  The drive unit 2A is provided with an operation position detection unit 8. The operation position detection unit 8 counts the drive rotation speed and the drive rotation direction of the drive shaft 21, thereby the current operation position of the opening / closing body 10. Is to be detected. For the operation position detector 8, a Hall IC, a rotary encoder, or the like can be used. The increase and decrease of the pulse count correspond to the opening / closing direction of the opening / closing body, and the increase / decrease amount corresponds (preferably substantially proportional) to the opening / closing movement amount of the opening / closing body. That is, based on the result detected by the operation position detection unit 8, the control unit 7 performs control such as stopping, continuing, and adjusting the drive speed of the drive unit 2A.

  The fully open position P1, the fully closed position P2, and the origin position P3 are set by the pulse count of the operation position detector 8. For example, the pulse count setting value at the fully open position P1 is set to “6050”, the pulse count setting value at the fully closed position P2 is set to “4050”, and the pulse count setting value at the origin position P3 is set to “6000”. Keep it. When the pulse count signal output from the operation position detection unit 8 becomes “6050”, the opening operation of the opening / closing body 10 is stopped in a state where the lower end portion 10A of the opening / closing body 10 reaches the fully open position P1, and the operation position Control is performed so that the closing operation of the opening / closing body 20 is stopped when the lower end portion 10A of the opening / closing body 10 reaches the fully closed position P2 when the pulse count signal output from the detection unit 8 reaches “4050”. The unit 4 controls the drive unit 2A. Note that the ratio of the width of the fully open position P1 region and the width of the fully closed position P2 region with respect to the opening height shown in FIG. 1 greatly exaggerates the ratio of the fully open position P1 region for convenience of explanation. It is different from the ratio.

  FIG. 5 is a block diagram illustrating a configuration of the operation signal determination unit 6. The operation signal determination unit 6 detects the output operation signal, determines what kind of the operation signal is, and the operation controlled by the control unit 7 so as to output the determination signal based on the determination result A signal detection unit 61 and an operation signal detection unit 62 controlled by the control unit 7 so as to detect the output determination signal and output an operation signal corresponding to the detected determination signal are provided.

  The operation signal detection unit 61 includes an operation type detection unit 61A that detects the type of an operation signal based on a predetermined operation from the operation unit 4, a time detection unit 61B that measures the output time of the operation signal, and a time detection unit 61B. And a timer 61C for measuring time. The operation signal detection unit 61 causes the operation signal detection unit 62 to output an operation type signal based on the operation signal detected by the operation type detection unit 61A, activates the timer 61C, and starts time measurement by the time detection unit 61B. It is controlled to let you. In addition, when the operation signal is not detected (operation unit 4 operation is stopped), the operation of the timer 61C and the time measurement of the time detection unit 61B are stopped and the measurement signal is output to the operation signal detection unit 62. It is controlled to let you.

  That is, the operation signal determination unit 6 detects the type of the operation signal from the operation unit 4 and the output time of the operation signal, thereby determining what the operation signal currently input from the operation unit 4 is. An operation signal corresponding to the determination signal based on the determination result is output. For example, as shown in Table 1, when the operation of the operation unit 4 is a fully open position setting operation, it is detected whether the operation signal is a simultaneous operation of the open operation unit 40 and the stop operation unit 42, and the operation It is detected whether or not the signal input time is 3 seconds. When the operation signal is the simultaneous operation of the opening operation unit 40 and the stop operation unit 42 and the output time of the operation signal is 3 seconds, it is determined that the current operation signal is the full open position setting operation signal, and this full open A fully open position setting operation signal based on the position setting operation signal is output. And the operation | movement shown in Table 1 of the switch 3 based on the fully opened position setting operation signal output is performed.

  Hereinafter, the control for notifying the end of the fully open setting and the fully closed setting of the opening and closing body 10 by operating the braking unit 2B at the end of the fully open setting and the fully closed setting of the opening and closing body 10 will be specifically described. FIG. 6 is a block diagram showing a configuration of the switchgear 1 including a specific configuration of the control unit 7.

  The control unit 7 includes a storage unit 70, an operation signal determination control unit 71, an opening / closing control unit 72, an operation position setting switching control unit 73, a fully open position setting preparation control unit 74, a fully open position setting control unit 75, and a fully closed position setting preparation control. Unit 76, fully closed position setting control unit 77, operation position setting end control unit 78, origin correction control unit 79, and CPU (not shown), and control unit 7 is output by operation of operation unit 4. Various controls are performed based on the operation signals determined and output by the operation signal determination unit 6 and the origin correction operation signal output from the origin detection unit 8.

  The storage unit 70 includes various programs such as various programs executed by the CPU, various application programs, operation type data of the operation unit 4 for causing the switch 3 to perform the operations shown in Table 1, operation data corresponding to the operation data, and the like. ROM storing data, fully open position data, fully closed position data, origin position data, RAM for temporarily storing the aforementioned pulse count and calculation results, etc., from origin position P3 to fully open position P1 and fully closed position P2. A nonvolatile memory (such as an EEPROM) that stores the value of the pulse count amount related to the distance as setting data that is retained even when the power is turned off is provided. The operation signal determination control unit 71, the opening / closing control unit 72, and the operation position setting are provided. Switching control unit 73, fully open position setting preparation control unit 74, fully open position setting control unit 75, fully closed position setting preparation control unit 76, fully closed position Setting control unit 77, the operation position setting end control unit 78, out of the various programs and data on the basis of a request origin correction control unit 79 is performed.

  The operation signal determination control unit 71 causes the operation signal determination unit 6 to determine the type of the operation signal based on the operation type data corresponding to the operation signal from the operation unit 4, and the operation corresponding to the determined operation type signal Operation signal output control for outputting an operation signal based on data is performed.

  The open / close control unit 72 performs manual operation control for driving the drive unit 2A based on the open / close operation signal from the operation signal determination unit 6 and stopping the drive of the drive unit 2A based on the stop operation signal. is there. Further, automatic operation control for stopping the driving of the drive unit 2A is performed based on the pulse count signal output from the operation position detection unit 8 based on the opening / closing operation signal from the operation signal determination unit 6.

  In the automatic operation control, the opening / closing control unit 72 detects the pulse count signal output from the operation position detection unit 8, and when the pulse count signal detected in the opening operation matches the fully opened position data, the drive unit 2A The driving is stopped, and when the pulse count signal detected in the closing operation matches the fully closed position data, the driving of the driving unit 2A is stopped.

  Based on the operation position setting switching operation signal from the operation signal determination unit 6, the operation position setting switching control unit 73 performs fully open position setting preparation, fully open position setting, fully closed position setting after power-on or from a normal opening / closing operation state. The control is performed so that the preparation and the fully closed position setting become effective. In addition, the operation signal from the operation signal determination unit 6 by various operations of the operation unit 4 after the switching control is a signal for performing fully open position setting preparation, fully open position setting, fully closed position setting preparation, and fully closed position setting. Control to be.

  The fully open position setting preparation control unit 74 determines the speed of the opening operation of the opening / closing body 10 based on the open signal from the operation unit 4 based on the fully open position setting preparation operation signal from the operation signal determination unit 6. Is controlled to be lower than the speed of the opening operation. By such control, it is possible to easily stop the opening / closing body 10 at the fully open position by visual observation. The control for lowering the speed of the opening operation may be a control for decreasing the speed from the beginning of the opening operation, or the same speed as the normal opening operation at the beginning of the opening operation, so that the speed decreases from near the fully opened position. It may be controlled.

  The fully open position setting control unit 75 causes the storage unit 70 to output the pulse count signal detected by the operation position detection unit 8 based on the fully open position setting operation signal from the operation signal determination unit 6 after preparation for full open position setting. Control is performed to store (overwrite) fully open position data. Furthermore, the brake unit 2B is controlled to release the brake and to return from the brake release state to the brake state.

  The fully closed position setting preparation control unit 76 determines the speed of the closing operation of the opening / closing body 10 by the closing operation of the operation unit 4 based on the fully open position setting preparation operation signal from the operation signal determining unit 6. Control is performed so as to be lower than the speed of the closing operation. By such control, it is possible to easily stop the opening / closing body 10 at the fully closed position by visual observation. The control for lowering the speed of the closing operation may be a control for reducing the speed from the beginning of the closing operation, or the same speed as the normal closing operation at the beginning of the closing operation, so that the speed is reduced from near the fully closed position. It is also possible to use control.

  The fully closed position setting control unit 77 outputs the pulse count signal detected by the operation position detection unit 8 to the storage unit 70 based on the fully closed position setting operation signal from the operation signal determination unit 6 after preparation for the fully open position setting. Thus, the control for storing (overwriting) the fully closed position data and the brake release operation of the braking unit 2B and the control for returning from the brake release state to the brake state are performed.

  The operation position setting end control unit 78 ends the above-described full-open position setting control and full-close position setting control based on both the full-open position setting operation signal and the full-close position setting operation signal. The switching control is performed so that the opening / closing operation control becomes effective. In this control, for example, the fully open position setting operation signal and the fully closed position setting operation signal are counted, and when both the operation signals are counted, the fully open position setting control and the fully closed position setting control are finished. Is mentioned.

  The origin correction control unit 79 is based on the origin signal output from the origin detection unit 8 based on the origin position correction signal from the operation unit 4 when returning from the non-power supply state due to a power failure or maintenance to the power supply state. Thus, the origin correction control at the time of power supply return for correcting the above-described origin position data stored in the storage unit 70 is performed.

  As an example of the above-described origin correction control, the position detection signal from the operation position detector 8 is a signal that the lower end 10A of the opening / closing body 10 is on the closing direction side P20 except for the origin position P and excluding the fully closed position P2. If there is, the drive unit 2A is driven to open the opening / closing body 10 until the lower end 10A of the opening / closing body 10 exceeds the origin position P3, and after that, the lower end 10A of the opening / closing body 10 is moved to the origin. When the lower end portion 10A of the opening / closing body 10 matches the origin position P3 in the closing operation, the origin detection of the origin detection unit 3 is performed, and this origin detection unit is driven. 3 is a control for correcting the above-mentioned origin position data based on the origin detection signal from 3.

  The origin correction control unit 79 further controls the drive unit 2A to drive the opening / closing body 10 so as to open after the input of the above-described origin detection signal. At this time, when the pulse count signal from the operation position detection unit 8 is a signal that the lower end 10A of the opening / closing body 10 has reached the fully open position P1, the opening / closing control unit 71 drives the drive unit 2A as described above. Is supposed to stop.

  The origin correction control unit 79 further performs control to invalidate the normal opening / closing instruction of the opening / closing body 10 performed to the opening / closing control unit 71. In the state where the origin detection unit 3 is performing the origin detection operation in this origin correction control, the drive unit 2A is not driven to perform a normal opening / closing operation.

  The origin correction control unit 79 further performs control to end the origin correction control after the opening / closing body 10 reaches the fully open position P1 after detecting the origin, and based on the opening / closing signal from the operation unit 4, the driving unit 2A. Is controlled to drive a normal opening / closing operation.

  The origin correction control of the origin correction control unit 79 is not limited to the exemplified control, and may be any control that can correct the origin during the opening / closing operation of the opening / closing body 10. For example, the origin detection may be performed when the lower end portion 10A of the opening / closing body 10 matches the origin position P every time the opening / closing body 10 is opened or closed. In the case of this origin correction control, the origin correction can be performed even during the normal opening / closing operation of the opening / closing body 10.

  Note that the operation order of the fully open position setting and the fully closed position setting described above is arbitrary, and it is only necessary to determine which one is to be performed first in consideration of efficiency depending on the stop position of the opening / closing body 10. In the operation position setting switching control, the opening operation, the closing operation, and the stop operation are simultaneously performed for 3 seconds or more, so that a fully open position setting preparation control unit 74, a fully open position setting control unit 75, a fully closed position setting preparation control unit 76, Although the control of the fully closed position setting control unit 77 is validated, in this control as well as the control of the fully open position setting control unit 73 and the fully closed position setting control unit 74, the braking unit 2B is operated and the braking unit 2B is operated. The operation position setting switching end may be notified by the operation sound.

  According to the control unit 7, it is possible to perform control for notifying the end of setting of the fully open position and the fully closed position of the opening / closing body 10 using the contact sound (operation sound) of the existing braking unit 2 </ b> B in the opening / closing device 1. . Further, switching control from full opening position setting control and full closing position setting control to normal opening / closing operation control of the opening / closing body 10 and origin correction control of the opening / closing body 10 can be performed.

  According to the opening / closing device 1 of the present embodiment, when the opening / closing body 10 is set to the fully open position and the fully closed position, the brake unit 2B is operated to the brake release state by operating the operation unit 4 for 3 seconds or more. Control to operate from the state to the braking state is performed, and the end of setting of the fully open position and the fully closed position of the opening / closing body 10 can be notified by a contact sound (operation sound) generated when the braking unit 2B is operated by this control.

  That is, since the opening / closing apparatus 1 of the present embodiment uses the contact sound (operation sound) of the existing braking unit 2B to notify the end of the setting of the fully open position and the fully closed position of the opening / closing body 10, Without equipping the part 4 with components such as a sound generator and an LED, it is possible to clarify the end of the setting of the fully open position and the fully closed position of the opening and closing body 10 and to increase the accuracy of setting the operating position of the opening and closing body. Therefore, even if the fully open position and the fully closed position of the opening / closing body 10 are frequently set, it is possible to set an accurate operation position, and the size of the operation unit 4 can be reduced by not increasing the number of parts. And cost reduction of the switchgear 1 can be achieved.

  7 to 11 are flowcharts of programs of the fully open position setting control method and the fully closed position setting control method of the opening / closing body 10. This program is a program that is activated by turning on the power to the switchgear 1 (step S1). At this time, braking of the braking portion 2 </ b> B acts on the opening / closing body 10, and the closing operation due to the weight of the opening / closing body 10 is braked. The braking of the braking unit 2B is continued unless various signals for releasing the braking are output. The various signals for releasing the braking are the above-described fully open position setting operation signal and fully closed position setting operation signal, and further, a disaster occurrence signal when the opening / closing body 10 is closed in the event of a disaster or the like.

[Operation position setting switching step]
When the operation position setting switching instruction is issued after the program is started (step S2), the state is switched to a state where the fully open position setting and the fully closed position can be set (step S3). The operation of the opening / closing machine 3 is limited to the operation at the time of setting the fully open position and the position of the fully closed position in the operation of the operation unit 4 after step S3.

[Fully open position setting preparation step]
When the opening / closing body 10 is instructed to be opened after the operation position setting is switched (step S4), a fully open position setting preparation signal is output (step S5), and an opening operation signal is output (step S6). 10 is started (step S7). The opening speed of the opening / closing body 10 is lower than the speed of the normal opening operation by the fully open position setting preparation signal. When a stop instruction is given when the opening / closing body 10 reaches the fully open position (step S8), a stop operation signal is output (step S9), the opening operation stops (step S10), and the drive unit 2A enters a braking state (step S10). Step S11). In this fully open position setting preparation step, in a state where the opening / closing body 10 is stopped at the fully opened position, the opening / closing body 10 is braked by the braking unit 2B in addition to the braking of the driving unit 2A. Even when the drive unit 2A cannot be braked due to the occurrence of the above or the like, the closing operation of the opening / closing body 10 is braked.

[Fully open position setting step]
When a fully open position setting instruction is issued after the opening / closing body 10 is stopped at the fully open position (step S12), a fully open position setting operation signal is output (step S13). Based on this fully open position setting operation signal, the operation position detector 8 The pulse count signal detected in (1) is output to the storage unit 70 (step S14), and the fully open position data based on this pulse count signal is stored (overwritten) (step S15). In addition, the braking unit 2B performs a braking release operation and a return operation from the braking release state to the braking state (step S16), and a contact sound (operation sound) generated during this operation notifies the end of the fully open position setting (step S17). Further, it is counted that the fully open position setting operation signal is output (step S18), and this count data is temporarily stored (step S19).

[Fully closed position setting preparation step]
When the opening / closing body 10 is instructed to close after the fully opened position is set (step S20), a fully closed position setting preparation signal is output (step S21), and the drive unit 2A starts driving (step S22). The closing operation is started (step S23). The opening speed of the opening / closing body 10 is lower than the speed of the normal closing action by the fully open position setting preparation signal. When a stop instruction is issued when the opening / closing body 10 reaches the fully closed position (step S24), a stop operation signal is output (step S25), the closing operation is stopped (step S26), and the drive unit 2A enters a braking state. (Step S27). In this fully closed position setting preparation step, in a state where the opening and closing body 10 is stopped at the fully closed position, the opening and closing body 10 is braked by the braking portion 2B in addition to the braking of the driving portion 2A. Even when a power failure or the like occurs and the drive unit 2A cannot be braked, the closing operation of the opening / closing body 10 is braked.

[Fully closed position setting step]
When a fully closed position setting instruction is issued after the opening / closing body 10 is stopped at the fully closed position (step S28), a fully closed position setting operation signal is output (step S29), and an operation is performed based on the fully closed position setting operation signal. The pulse count signal detected by the position detection unit 8 is output to the storage unit 70 (step S30), and the fully closed position data based on this pulse count signal is stored (overwritten) (step S31). In addition, the brake unit 2B performs a brake release operation and a return operation from the brake release state to the brake state (step S32), and an operation sound generated during this operation notifies the end of the fully closed position setting (step S33). Further, it is counted that the fully closed position setting operation signal is output (step S34), and this count data is temporarily stored (step S35).

[Operation position setting end step]
The count data obtained by counting the fully opened position setting operation signal and the count data obtained by counting the fully closed position setting operation signal are read (step S36). When both count data are read, the fully opened position setting signal and the fully closed position are read. A setting signal is output (step S37), switching is performed so that the normal opening / closing operation control of the opening / closing body 10 becomes effective (step S38), the stored count data is erased (step S39), and the opening / closing body 10 is fully opened. The program of the position setting method and the fully closed position setting method ends.

  According to the fully open position setting control method and the fully closed position setting control method of the present embodiment, when the fully open position setting and the fully closed position setting of the opening / closing body 10 are performed, the brake unit 2B is released by the operation of the operation unit 4 for 3 seconds or more. It is possible to perform control to operate from the braking release state to the braking state. Therefore, it is possible to notify the end of the setting of the fully open position and the fully closed position of the opening / closing body 10 by the operation sound generated during the operation of the braking unit 2B by this control. In addition, when the opening / closing body 10 is stopped in the fully opened state and the fully closed state, the braking unit 2 </ b> B can perform control to brake the closing operation of the opening / closing body 10. Therefore, it is possible to brake the closing operation of the opening / closing body 10 when the opening / closing body 10 is set to the fully open position and when the fully closed position is set.

  FIG. 12 is a flowchart of the program of the operation signal determination control method. This program is a program that is activated by turning on the power to the switchgear 1 (step S1).

  When the opening operation unit 40, the closing operation unit 41, and the stop operation unit 42 are operated to perform target control after the program is started (step S2), operation type data corresponding to the operation signal performed in step S2 is obtained. While reading, the present operation signal is determined based on the operation type data (steps S3 to S9), and the determination signal is output based on the determination result (steps S10 to S16). The operation data corresponding to the output determination signal is read, and the operation signal is output based on the operation data (steps S17 to S23), whereby the control method program of the operation signal determination control unit 71 is completed.

  According to the operation signal determination control method of the present embodiment, it is possible to perform the operation signal output control for determining the type of the operation signal from the operation unit 4 and outputting the operation signal corresponding to the determination result.

  In the opening / closing device 1, a monitor lamp 9 such as an LED may be used in combination as a notification means for notifying the end of setting of the fully opened position and the fully closed position of the opening / closing body 10 (see FIG. 1). This monitor lamp 9 is an existing lamp used for notifying various abnormalities of the switchgear 1 and the end of origin correction. As shown in Table 2 below, the monitor lamp 9 depends on the number of blinks and the blinking time of the monitor lamp 9. Various abnormalities and origin corrections are announced.

  In other words, simultaneously with the notification of the end of the fully open position setting and the fully closed position setting of the opening / closing body 10 by the operation sound of the braking unit 2B, the notification of the specific monitor lamp 9 blinking time or blinking time indicating the completion of the setting is performed. By controlling with the control unit 7, it is possible to notify the end of the setting of the fully open position and the fully closed position of the opening / closing body 10 by two different notification means of hearing and vision, so that the user can more reliably The end of the fully open position setting and the fully closed position setting can be known.

  An abnormality in each part is detected by an abnormality detection unit 90 (see FIG. 1). When the abnormality detection unit 90 detects an abnormality, an abnormality signal is output to the control unit 7. The control unit 7 controls the monitor lamp 9 to blink on the basis of this abnormality signal. Further, in the origin correction, the fully open position setting, and the fully closed position setting, the monitor lamp 9 is controlled to blink based on the origin correction signal and the operation position setting signal output from the operation unit 4. Note that the blinking mode of the monitor lamp 9 in the abnormality detection, origin correction, full open position setting, and full close position setting of each part of the opening / closing device 1 is not limited to that shown in Table 2.

  In addition, this invention is not limited to illustrated embodiment, Implementation by the structure of the range which does not deviate from the content described in each item of a claim is possible. For example, the fully open position P1 of the opening / closing body 10 may be set to a position where the lower end portion 10A of the opening / closing body 10 is below the lower end portion 240 of the storage unit 100, or the fully closed position P2 of the opening / closing body 10 is opened / closed. The lower end portion 10A of the body 10 may be set to a position above the floor surface FL (not shown). That is, the fully open position P1 and the fully closed position P2 referred to in the present invention are positions arbitrarily set by the user, and are not limited to positions where the opening 1A is fully opened and fully closed.

  Further, the braking unit 2B of the present invention only needs to have a configuration that generates a contact sound (operation sound) during the braking release operation and the return operation from the braking release state to the braking state (not shown). Moreover, the drive part 2A of this invention should just have a structure which carries out a braking operation | movement at the time of the brake release operation | movement at the time of an operation position setting, and is not limited to the electromagnetic brake of a permanent magnet synchronous motor.

  In the present embodiment, the brake unit 2B is operated to generate an operation sound when the fully open position is set and when the fully closed position is set. However, the present invention is not used when the fully open position is set or the fully closed position is set. When the operation is set, the braking unit 2B may be operated to generate a contact sound (operation sound).
