Conventionally, even if a manual emergency stop switch was operated, or the emergency stop switch or dive stop device was activated, the power supply for the electric opening and closing device itself continued to function properly. Therefore, if the relay contacts melted or the CPU went out of control within the control device that controlled the operation of the opening and closing device, the opening and closing device could malfunction and the operation of the opening and closing device could not be stopped.

The present invention has been made in consideration of the above points, and aims to improve safety by preventing malfunction of the opening and closing body when the emergency stop switch is operated, or when the emergency stop switch or the sudden descent stop device is activated.

The first feature of the opening/closing body device of the present invention is that the opening/closing body device includes an opening/closing means provided on the periphery of the opening, an opening/closing machine for electrically operating the opening/closing means, a control means for electrically controlling the operation of the opening/closing means by driving the opening/closing machine, a power supply device for supplying power based on a commercial power source to the control means, an emergency stop switch for manually emergency stopping the operation of the opening/closing means, an emergency stop switch for automatically emergency stopping the operation of the opening/closing means when the opening/closing means passes through a predetermined upper limit position and rises, or passes through a predetermined lower limit position and falls, and a sudden descent stop device for automatically stopping the descent of the opening/closing means when the descent speed of the opening/closing means exceeds a predetermined value, and includes a power cutoff means for cutting off the power supplied from the power supply device to the control means, and an instruction means for instructing the control means to stop the operation of the opening/closing means when the emergency stop switch is operated or the emergency stop switch or the sudden descent stop device is operated, and then instructing the power cutoff means to cut off the power supplied from the power supply device to the control means.

A power cut-off means for cutting off the power supplied from the power supply device to the control means and an instruction means are provided, and when the emergency stop switch is operated, or the emergency stop switch or the rapid descent stop device is activated, the instruction means instructs the control means to stop the operation of the opening/closing means, and then instructs the power cut-off means to cut off the power supplied from the power supply device to the control means. Therefore, after the instruction to stop the operation of the opening/closing means is given, the power is cut off, and malfunction of the opening/closing body is prevented.

The opening and closing means is composed of an opening and closing member such as a shutter curtain that electrically opens and closes openings such as entrances and windows, or internal passageways and spaces in structures such as buildings, including houses, buildings, factories, warehouses, and garages. When the opening and closing means is a shutter curtain, it is stored in the upper part, which is one of the peripheral parts of the opening in a building, and the shutter curtain passes through a lintel or the like and descends, electrically opening and closing the opening. In addition, the opening and closing means may be stored in the lower part of the opening and electrically opened and closed by an upward movement. Also, the opening and closing means may include those that can fully close the opening when closed, and those that cannot.

The second feature of the opening/closing body device of the present invention is that in the opening/closing body device described in the first feature, the instruction means has a logic circuit that transmits a plurality of confirmation signals via the emergency stop switch, the emergency stop switch, and the rapid drop stop device, respectively, and when any of the confirmation signals changes, outputs a stop signal to the control means to instruct the operation of the opening/closing means to stop, and then outputs a cutoff signal to the power cutoff means to instruct the cutoff of the power supplied from the power supply device to the control means when a time longer than the time required from when the operation of the opening/closing means is started to be stopped until the opening/closing means actually stops has elapsed.

A logic circuit provided in the instruction means sends multiple confirmation signals separately via the emergency stop switch, emergency stop switch, and sudden drop stop device, and when any of the confirmation signals changes, a stop signal is output to the control means to instruct the operation of the opening and closing means to stop. After that, when a time longer than the time required from when the opening and closing means began to stop operating until the opening and closing means actually stops has elapsed, a cutoff signal is output to the power cutoff means to instruct the power supplied from the power supply device to the control means to be cut off, so that after the operation of the opening and closing means is stopped, the power supplied from the power supply device is cut off.

A third feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first or second feature, the instruction means has a start-up switch for manually instructing the power supply cutting means to release the power supply cut-off, and the power supply cutting means releases the power supply cut-off when the start-up switch is operated.
Unless the manual start switch is operated, the power cut-off by the power cut-off means is not released, and the effect of preventing malfunction of the opening/closing body is maintained, thereby improving safety.

A fourth feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the first, second, or third feature, the instruction means has an emergency stop switch and an operation switch for manually instructing the control means to perform each of the opening and closing operations of the opening/closing means, arranged together, and the control means controls each of the opening and closing operations of the opening/closing means in response to operation of the operation switch.
By arranging the emergency stop switch and the operation switch for manually instructing the control means to open and close each operation of the opening and closing means, together with the instruction means, operability is improved.

This is a control method for an opening/closing body device, which corresponds to the opening/closing body device described in the first aspect.

A second feature of the control method for an opening/closing body device of the present invention is that, in the control method for an opening/closing body device described in the first feature, a plurality of confirmation signals are passed separately via an emergency stop switch, an emergency stop switch, and a rapid descent stop device, and when any of the confirmation signals changes, a stop signal is output to the control means instructing it to stop operating the opening/closing means, and thereafter, when a time longer than the time required from when the stopping of the operation of the opening/closing means begins to when the opening/closing means actually stops is elapsed, a cut-off signal is output to the power cut-off means instructing it to cut off the power supplied from the power supply device to the control means.
This is a control method for an opening/closing body device, which corresponds to the opening/closing body device described in the second aspect.

This is a control method for an opening/closing body device, which corresponds to the opening/closing body device described in the fourth aspect.

The present invention provides an opening/closing body device that can prevent malfunction of the opening/closing body and improve safety when the emergency stop switch is operated, or when the emergency stop switch or the sudden descent stop device is activated.

A preferred embodiment of an opening/closing body device according to the present invention will now be described with reference to the attached drawings. In this embodiment, a shutter device equipped with a shutter curtain that opens and closes vertically will be described as an example of an opening/closing means. Figure 1 is a diagram showing the schematic configuration of a shutter device, which is an opening/closing body device according to one embodiment of the present invention. In Figure 1, the opening/closing body device 10 is a shutter device that opens and closes the opening of an entrance and exit vertically.

The opening/closing device 10 is installed at the opening of a building, and basically comprises a shutter case 11, a shutter curtain 12, guide rails 13, 14, a winding shaft 15, a chain 16, a motor 17, a position detection device 172, a control device 18, an obstacle detection device 185, a power supply device 20, a power cut-off device 40, a stop/cut-off instruction unit 50, an emergency stop switch 60, and a sudden descent stop device 70.

Under normal circumstances, this opening/closing body device 10 drives the motor 17, which is an opening/closing device, to control opening and closing in response to the operation of the operation switch 19 of the stop/shutoff command unit 50 described below. Furthermore, in this opening/closing body device 10, the open state in which the shutter curtain 12 is wound up on the winding shaft 15 is maintained by a mechanical holding mechanism (not shown), and if an emergency signal BS indicating the occurrence of a fire or the like is input from the outside to the control device 18 in this open state, the holding mechanism releases the open state, and the shutter curtain 12 naturally descends under its own weight, automatically closing the opening.

The guide rails 13 and 14 are provided on both ends of the opening in the building so as to contact both ends of the shutter curtain 12, and are made of a metal member or an equivalent member having a guide groove with a U-shaped cross section that spans from the lintel to the floor. The shutter curtain 12 rises and falls along the guide grooves of the guide rails 13 and 14 to open and close the opening.

The winding shaft 15 is rotatably mounted on both ends of the shutter case 11, and winds and unwinds the shutter curtain 12. The chain 16 connects a driving sprocket mounted on the rotating shaft of the motor 17 to a driven sprocket mounted on the rotating shaft of the winding shaft 15. Therefore, the rotational driving force of the motor 17 is transmitted to the winding shaft 15 via the chain 16, and when the motor 17 rotates, the winding shaft 15 rotates via the chain 16, controlling the opening and closing operation of the shutter curtain 12.

The motor 17 is provided with a position detector 172 (see FIG. 2) for detecting its rotational position, i.e., the open/closed position and open/closed state of the shutter curtain 12. This position detector 172 is composed of a pulse-generating rotary encoder or the like. A pulse signal corresponding to the rotation of the motor 17 is output to the control device 18, so that the control device 18 calculates the rotational position of the motor 17 and the position of the tip of the shutter curtain 12 at the opening on the closed side based on the generation status of this pulse.

The control device 18 is configured as a microcomputer, and receives power from the commercial power line AC via the power supply device 20. The control device 18 controls the rotation of the motor 17 based on control signals corresponding to the operation states of the operation buttons on the operation switch 19 of the stop/shutoff instruction unit 50 (described later), a detection signal from the obstacle detection device 185, and a signal from the position detection device 172 provided on the motor 17, and releases the holding mechanism based on an emergency signal BS.

The emergency signal BS is a 24V signal supplied from an external control room in the event of an emergency such as a fire, and is input to a harm prevention interlocking relay (not shown) in the control device 18. In addition to or instead of the input of the emergency signal BS from the outside, a temperature sensor may be provided inside the shutter case 11 near the opening of the lintel, i.e., the part where the shutter curtain 12 rises and falls. This temperature sensor may be configured to be a high-temperature bimetal thermostat with an automatic reset type B contact whose contacts are always on and open when the contacts reach a specified temperature (any temperature between 100 and 300 degrees Celsius), and when the contacts are open, a signal indicating that a fire has occurred may be output as a signal equivalent to the emergency signal BS.

The obstacle detection device 185 has a transmitter installed at the lower end (seat plate) of the shutter curtain 12. When an obstacle is detected, the device transmits a detection signal corresponding to the movement of the built-in seat plate switch to the control device 18, and when the seat plate switch returns to its original position due to the removal of the obstacle, a return signal is also transmitted. The transmission of the signal from the transmitter of the obstacle detection device 185 to the control device 18 is not limited to a wired system as shown in the figure, but may be a wireless system that operates using a battery as a power source. In addition, a seat plate switch that moves when an obstacle comes into contact with the lower end of the shutter curtain 12 may be provided, and a tape switch installed along the height direction of the guide rails 13 and 14 may be pressed by the force of the seat plate moving when the obstacle comes into contact, or a detection signal may be output from the tape switch to the control device 18 via a wire. In addition, a photoelectric tube, LED, or other light emitting/receiving sensor may be provided at the opening, and an obstacle may be detected without contact by image recognition, etc.

The power supply device 20 inputs AC power from the power line AC of a commercial power source, and supplies AC power to the control device 18 if the motor 17 is an AC motor, or DC power obtained by converting the AC power to DC if the motor 17 is a DC motor.
In this embodiment, the power supply device 20 is installed inside the shutter case 11 , but the power supply device 20 may be installed outside the shutter case 11 .

As described below, when a power cutoff signal is input from the stop/cutoff instruction unit 50, the power cutoff device 40 cuts off the power supplied from the power supply device 20 to the control device 18.
In this embodiment, the power cutoff device 40 is provided between the power supply device 20 and the control device 18 , but the power cutoff device 40 may be provided in front of or inside the power supply device 20 .

The stop/shutoff instruction unit 50 includes the operation switch 19, an emergency stop switch 50a, a start switch 50b, and an abnormality lamp 50c.
The operation switch 19 has an up (open) button 19A, a stop (stop) button 19B, and a down (close) button 19C as control switches corresponding to the opening/closing and stopping operations, and outputs control signals according to the operation states of each of these buttons to the control device 18. Although not shown in Fig. 1, the control device 18 may also be operable by a wireless remote control device.

The emergency stop switch 50a is a manual button that an operator presses by hand in the event of an emergency to instruct an emergency stop of the operation of the shutter curtain 12. When the emergency stop switch 50a is operated, an abnormality lamp 50c is turned on to notify the operator that the emergency stop switch 50a has been activated. The abnormality lamp 50c is also turned on when the emergency stop switch 60 or the rapid descent stop device 70, which will be described later, is activated.
The start switch 50b is a manual button for canceling the emergency stop caused by the emergency stop switch 50a and restarting the operation of the shutter curtain 12. Note that the start switch 50b may be configured to be operated at all times when the operation of the shutter curtain 12 is started.

In this embodiment, operability is improved by arranging an emergency stop switch 50a and an operation switch 19 for manually instructing the control device 18 to open/close and stop the shutter curtain 12, side by side on the stop/shutoff instruction unit 50.
However, the operation switch 19 may be provided separately from the stop/shutoff instruction unit 50 .

The emergency stop switch 60 is an automatic switch for emergency stopping the operation of the shutter curtain 12 when the shutter curtain 12 passes through a predetermined upper limit position and rises, or passes through a predetermined lower limit position and falls. A contact-type mechanical detection device is used as this emergency stop switch 60. The emergency stop switch 60 operates by detecting that the shutter curtain 12 has passed through a predetermined upper limit position and rises, or that it has passed through a predetermined lower limit position and falls.
The emergency stop switch 60 may be an optical non-contact detection device.

The sudden drop stop device 70 is a device that automatically stops the descent of the shutter curtain 12 when the descent speed of the shutter curtain 12 exceeds a predetermined value. The sudden drop stop device 70 is equipped with a microswitch that operates when it detects that the descent speed of the shutter curtain 12 exceeds a predetermined value, and a brake mechanism that applies a brake to the rotating shaft of the winding shaft 15 when the microswitch operates, immobilizing the winding shaft 15.

Fig. 2 is a diagram for explaining the operation of each device in the shutter device shown in Fig. 1. The control device 18 controls the motor 17 using power supplied from the power supply device 20 via the power cutoff device 40, based on signals from the stop/cutoff command unit 50, the obstacle sensor 185, and the position detector 172, as well as the emergency signal BS.
In addition, the stop/shutoff instruction unit 50 receives operation confirmation signals, which will be described later, from the emergency stop switch 60 and the sudden descent stopping device 70 .
In FIG. 2, the connection relationship of the commercial power source to components other than the control device 18 is omitted.

FIG. 3 is a diagram showing a circuit configuration of a control device for a shutter device and a stop/shutoff instruction unit according to an embodiment of the present invention.
The control device 18 of the present embodiment includes a motor drive circuit 18a, a CPU 18b, and the like.
The motor drive circuit 18a is composed of an IPM (Intelligent Power Module: high-performance power semiconductor element) driver and the like, and outputs AC power or DC power supplied from the power supply device 20 to the control device 18 to the motor 17 under the control of the CPU 18b, thereby driving the motor 17.
The CPU 18b controls the driving of the motor 17 by the motor driving circuit 18a.

The stop/shutdown instruction unit 50 includes a PLC (Programmable Logic Controller) 51 as a logic circuit, in addition to the above-mentioned operation switch 19, emergency stop switch 50a, start switch 50b, and abnormality lamp 50c.
The PLC 51 receives signals from an emergency stop switch 50 a , a start switch 50 b , an emergency stop switch 60 , and a sudden descent stopping device 70 .
In addition, the CPU 18b of the control device 18 and the PLC 51 of the stop/shutdown instruction unit 50 may be the same (one unit performing both functions).

FIG. 4 is a diagram for explaining the operation of the PLC.
The emergency stop switch 50a is a normally-closed contact switch, and receives an operation confirmation signal from the PLC 51. The emergency stop switch 50a cuts off the operation confirmation signal from the PLC 51 when operated.
Similarly, the emergency stop switch 60 is a normally-closed contact switch, and an operation confirmation signal is applied from the PLC 51 to the emergency stop switch 60. The emergency stop switch 60 operates upon detecting that the shutter curtain 12 has passed a predetermined upper limit position and risen, or that the shutter curtain 12 has passed a predetermined lower limit position and fallen, and cuts off the operation confirmation signal from the PLC 51.
The sudden descent stopping device 70 is provided with a microswitch 70a with normally closed contacts, and an operation confirmation signal is applied to the microswitch 70a from the PLC 51. The microswitch 70a operates upon detecting that the descent speed of the shutter curtain 12 exceeds a predetermined value, and cuts off the operation confirmation signal from the PLC 51.

When any one of the multiple operation confirmation signals that are energized separately via the emergency stop switch 50a, the emergency stop switch 60, and the microswitch 70a of the sudden descent stop device 70 is cut off, the PLC 51 outputs a shutter stop signal to the CPU 18b of the control device 18 to instruct the stop of the operation of the shutter curtain 12. At this time, the PLC 51 also outputs a lighting signal to the abnormal lamp 50c to instruct it to light up.
When the CPU 18b of the control device 18 receives a shutter stop signal from the PLC 51, it stops the operation of the shutter curtain 12 regardless of the operation state of the operation switch 19. In addition, the abnormal lamp 50c receives a turn-on signal from the PLC 51 and turns on.

After that, when a predetermined time has elapsed, the PLC 51 outputs a power cutoff signal to the power cutoff device 40 to instruct the power cutoff device 40 to cut off the power supplied from the power supply device 20 to the control device 18. The power cutoff device 40 is composed of an electromagnetic switch (magnetic switch) and the like, and cuts off the power supplied from the power supply device 20 to the control device 18 when the power cutoff signal is input from the PLC 51.
At this time, the predetermined time is set to be longer than the time required from when the shutter curtain 12 starts to stop operating until the shutter curtain 12 actually stops operating. As a result, after the shutter curtain 12 stops operating, the power supplied from the power supply device 20 is cut off.

The start-up switch 50b is a normally open contact switch, and when the start-up switch 50b is operated, an operation signal is passed from the PLC 51 through the start-up switch 50b. When the operation signal is passed through the start-up switch 50b, the PLC 51 outputs a release signal to the power cut-off device 40, which instructs the power cut-off device 40 to release the cut-off of the power supplied from the power supply device 20. When the power cut-off device 40 receives the release signal from the PLC 51, it releases the cut-off of the power supplied from the power supply device 20 to the control device 18.
Unless the manual start switch 50b is operated, the power cut-off by the power cut-off device 40 is not released, and the effect of preventing malfunction of the shutter curtain 12 is maintained, thereby improving safety.

In the embodiment described above, a logic circuit (PLC 51) that instructs the power cutoff device 40 to cut off the power supplied from the power supply device 20 to the control device 18 after the emergency stop switch 50a is operated or after the emergency stop switch 60 or the sudden drop stop device 70 is activated is provided in the stop/cutoff instruction unit 50 together with the emergency stop switch 50a, but a device having a similar function may be provided in equipment other than the equipment in which the emergency stop switch 50a is provided.

The opening/closing device of the present invention can also be applied to, for example, shutter devices, window shutter devices, blind devices, roller screen devices, curtain devices, movable partition devices, sliding door devices, swing door devices, folding door devices, gate devices, awning devices, waterproof board devices, etc.
