Description

The present invention relates to an opening/closing body device and a control method for the opening/closing body device that are configured to separate openings in structural bodies, including buildings such as houses, buildings, factories, warehouses, and garages, using opening/closing bodies such as shutters, and in particular to an opening/closing body device and a control method for the opening/closing body device that are suitable for preventing malfunctions when detecting the displacement of objects around the opening and automatically operating the opening/closing body.

Opening and closing body devices such as shutter curtains are installed at the entrances and windows of structural bodies including houses, buildings, factories, warehouses, garages, and other buildings, or at openings such as internal passages and spaces, and the openings are opened and closed by moving the opening and closing body. This opening and closing body device is configured to unfold and lower from the top of the opening an opening and closing body such as a slat curtain made of many rectangular slat materials, a pipe grill curtain made of many pipe materials connected with link materials, a panel curtain made of one panel material or many connected panels, a net curtain made of a net material, a sheet curtain made of a sheet material made of synthetic resin or cloth fiber, or a composite curtain made of a composite material of these materials, etc., to close the entire opening. In such opening and closing body devices, the opening and closing operation of the opening and closing body is often performed electrically. Examples of electrically operated opening and closing body devices include an electric shutter device, an electric door device, and an electric awning device.

In general, an electric opening and closing body device is configured such that an opening and closing body for opening and closing an opening and closing space of a structure such as a building is raised and lowered by an opening and closing machine (motor, etc.) arranged in the ceiling of the structure or in the shutter case.

JP 2006-9450 A

For safety reasons, the power supply device that supplies commercial power to the control device of the opening and closing device is usually equipped with a circuit breaker that cuts off the flow of electricity from the commercial power to the power supply device. The circuit breaker cuts off the flow of electricity to the power supply device from the commercial power when an abnormal overcurrent flows through the power supply device due to an overload, short circuit, or other factor. When the circuit breaker is in the cut-off state, the operator must manually restore electricity.

If a non-contact sensor equipped with an optical sensor or the like is used as a sensor for detecting the displacement of objects around the opening, and this non-contact sensor is installed near the circuit breaker, when the circuit breaker in the cut-off state is energized and the sensor is turned on, the sensor detects and stores the presence of an operator or the like around the opening, and when the operator then moves away from the area around the opening, the sensor detects the displacement of objects around the opening, which could cause a malfunction in which the opening/closing body that was closed opens. In particular, if the circuit breaker and sensor are installed above the opening, the operator must climb onto a ladder or workbench to energize the circuit breaker, and the operator who energizes the circuit breaker, as well as the ladder or workbench, could cause the opening/closing body to malfunction.

The present invention has been made in consideration of the above points, and aims to provide an opening/closing body device that can detect the displacement of objects around the opening and closing body and prevent malfunctions when automatically operating the opening/closing body.

A first feature of the opening/closing body device of the present invention is that it comprises an opening/closing means provided on the peripheral portion of the opening, a circuit breaker for electrically operating the opening/closing means, a control means for driving the circuit breaker to electrically control the operation of the opening/closing means, a power supply device for supplying power based on a commercial power source to the control means, a circuit breaker for cutting off current to the power supply device from the commercial power source, and a sensor means provided near the circuit breaker for detecting displacement of objects around the opening and outputting a detection signal to the control means, and the control means has processing means for not turning on the sensor means when current is passed through the circuit breaker in the cut-off state, but turning on the sensor means after a predetermined time has elapsed, and controls the operation of the opening/closing means in accordance with the detection signal from the sensor means.
When the circuit breaker in the cut-off state is energized, the processing means does not turn on the sensor means, but turns on the sensor means after a predetermined time has elapsed, thereby ensuring time for the operator who energized the circuit breaker in the cut-off state to retreat from the vicinity of the opening, and preventing malfunction of the opening/closing means caused by an operator who was in the vicinity of the opening when the circuit breaker in the cut-off state was energized.

The opening and closing means is composed of opening and closing members such as shutter curtains that electrically open and close 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 open and close using an upward movement method, or the opening and closing means may be stored in the side and electrically move using a sliding movement method. Also, the opening and closing means may include those that can fully close the opening when closed, and those that cannot.

A 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, it is provided with an instruction means for an operator to instruct the control means to turn on the sensor means, and the processing means turns on the sensor means after a first predetermined time has elapsed since the circuit breaker was energized when the instruction means is not operated after the circuit breaker in an interrupted state is energized, and after a second predetermined time shorter than the first predetermined time has elapsed since the instruction means was operated when the instruction means was operated.
The system is provided with an instruction means for an operator to instruct the control means to turn on the sensor means, and when the instruction means is not operated after the circuit breaker in an off state is energized, the processing means turns on the sensor means after a first predetermined time has elapsed since the circuit breaker was energized, thereby ensuring that the operator who energized the circuit breaker has sufficient time to evacuate from the area around the opening.
In addition, when the indicating means is operated after the circuit breaker in the cut-off state is energized, the processing means turns on the sensor means after a second predetermined time, which is shorter than the first predetermined time, has elapsed since the indicating means was operated. Therefore, when the operator who energized the circuit breaker is ready to move away from the area around the opening, he or she can operate the indicating means to hasten the time at which the sensor means is turned on.

A third feature of the opening/closing body device of the present invention is that, in the opening/closing body device described in the second feature, an operating switch having a stop button for an operator to instruct the control means to stop the opening/closing means, and the stop button also serves as the instruction means.
Since the stop button of the operation switch also serves as instruction means for instructing the control means to turn on the sensor means, there is no need to provide an instruction means separately from the operation switch, and therefore no increase in equipment costs.

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, when a circuit breaker in an interrupted state is energized, the processing means prohibits the opening/closing means from descending without turning on the sensor means, and after turning on the sensor means, releases the prohibition on the descending of the opening/closing means.
When the circuit breaker in the cutoff state is energized, the processing means prohibits the lowering of the switching means without turning on the sensor means, and after turning on the sensor means, the prohibition of the lowering of the switching means is released, so that the lowering of the switching means is not performed while the sensor means is not operating, and safety is ensured.

A first feature of the control method for an opening/closing body device of the present invention is a control method for an opening/closing body device comprising an opening/closing means provided on the peripheral portion of an opening, a circuit breaker for electrically operating the opening/closing means, a control means for driving the circuit breaker to electrically control the operation of the opening/closing means, a power supply device for supplying power based on a commercial power source to the control means, a circuit breaker for cutting off current flow from the commercial power source to the power supply device, and a sensor means provided near the circuit breaker for detecting displacement of objects around the opening and outputting a detection signal to the control means, in which when current is passed through the circuit breaker in a cut-off state, without turning on the sensor means, after a predetermined time has elapsed, the control means turns on the sensor means and controls the operation of the opening/closing means in accordance with the detection signal from the sensor means.
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, an instruction means is provided for an operator to instruct the control means to turn on the sensor means, and when the instruction means is not operated after the circuit breaker in an interrupted state is energized, the control means turns on the sensor means after a first predetermined time has elapsed since the circuit breaker was energized, and when the instruction means is operated, after a second predetermined time shorter than the first predetermined time has elapsed since the instruction means was operated.
This is a control method for an opening/closing body device, which corresponds to the opening/closing body device described in the second aspect.

A third 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 second feature, an operating switch having a stop button that allows an operator to instruct the control means to stop the opening/closing means is provided to double as an instruction means.
This is a control method for an opening/closing body device, which corresponds to the opening/closing body device described in the third aspect.

A fourth 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, second, or third feature, when a circuit breaker in an interrupted state is energized, the sensor means is not turned on, and the control means prohibits the descent of the opening/closing means, and after the sensor means is turned on, the prohibition on the descent of the opening/closing means is released.
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 device that can detect the displacement of objects around an opening and prevent malfunctions when automatically operating the opening/closing body.

FIG. 2 is a diagram showing a circuit configuration of a control device for a shutter device according to an embodiment of the present invention. FIG. 4 is a diagram showing an example of a current supply circuit to a start-up sensor in the control device. 5 is a flowchart showing the operation of a control device for a shutter device according to one embodiment of the present invention. 10 is a flowchart showing the operation of a control device for a shutter device according to another embodiment of the present invention.

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 sheet curtain made of a sheet material 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 an opening of a building, and basically comprises a shutter case 11, a sheet 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, an operation switch 19, a power supply device 20, a breaker (circuit breaker) 30, and an activation sensor 40.
In normal operation, the opening/closing body device 10 drives a motor 17, which is an opening/closing mechanism, in response to the operation of an operating switch 19 or the activation of a start sensor 40, to control opening and closing.

The guide rails 13, 14 are provided on both ends of the building opening so as to contact both ends of the sheet 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 sheet curtain 12 rises and falls along the guide grooves of the guide rails 13, 14, opening and closing the opening.

The winding shaft 15 is rotatably mounted on both ends of the shutter case 11, and winds and unwinds the sheet curtain 12. A 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 sheet 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 sheet 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 opening at the tip of the closed side of the sheet curtain 12 based on the generation status of this pulse.

The control device 18 is configured as a microcomputer, and is supplied with 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, detection signals from the activation sensor 40, detection signals from the obstacle detection device 185, and signals from the position detection device 172 provided on the motor 17, and releases the holding mechanism based on an emergency signal BS.

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 a control signal according to the operation state 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 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 sheet 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 and turn off 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 sheet 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 sheet 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 moving force of the seat plate 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 receives AC power from the power line AC of a commercial power source, and supplies AC power when the motor 17 is an AC motor, or DC power obtained by converting the AC power into DC when the motor 17 is a DC motor, to the control device 18. Note that 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.
The breaker 30 cuts off the supply of electricity to the power supply device 20 from the commercial power source when an abnormal overcurrent flows through the power supply device 20 due to an overload, a short circuit, or the like. When the breaker 30 is in the cut-off state, an operator must manually restore the supply of electricity.

The activation sensor 40 is provided near the power supply device 20 in which the breaker 30 is provided, and has an irradiator that irradiates the periphery of the opening with a detection wave or detection light such as infrared light, and a detector that detects the intensity of the reflected wave or reflected light from the surrounding object of the opening. The activation sensor 40 detects and stores the intensity of the reflected wave or reflected light when the activation sensor 40 is turned on, and then, when the intensity of the detected reflected wave or reflected light changes, it outputs a detection signal to the control device 18 to instruct the operation of the sheet curtain 12, assuming that the surrounding object of the opening has been displaced. When the control device 18 inputs the detection signal from the activation sensor 40, it opens the sheet curtain 12 when the sheet curtain 12 is fully closed, and when the sheet curtain 12 is lowered, it reverses the operation of the sheet curtain 12 to raise the sheet curtain 12.

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, based on signals from the operation switch 19, the start sensor 40, the obstacle detection device 185, and the position detection device 172, as well as the emergency signal BS.
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 of a shutter device according to an embodiment of the present invention. The control device 18 of this embodiment is configured to include a motor drive circuit 18a, a CPU 18b, and a current supply circuit to the activation sensor shown in Fig. 4. The motor drive circuit 18a is composed of an IPM (Intelligent Power Module: high-performance power semiconductor device) driver and the like, and outputs AC power or DC power supplied to the control device 18 from a power supply device 20 to the motor 17 under the control of the CPU 18b to drive the motor 17.
The memory 18c stores data on a predetermined "predetermined time T" to be described later with reference to Fig. 5, or data on a predetermined "first predetermined time T1" and a "second predetermined time T2" to be described later with reference to Fig. 6. As will be described later, the "second predetermined time T2" is set to be shorter than the "first predetermined time T1".

Figure 4 is a diagram showing an example of a current supply circuit to the activation sensor in the control device. The converter 181 converts the AC or DC power input from the power supply device 20 into DC power (e.g., DC 24 V) required for the operation of the activation sensor 40. The DC/DC converter 182 reduces the output power of the converter 181 and outputs to the CPU 18b the DC power (e.g., DC 3.3 V) required for the operation of the CPU 18b. The switching element 183 is made of, for example, a transistor, and is controlled by the CPU 18b to supply the DC power output from the converter 181 to the activation sensor 40, turning the activation sensor 40 into an operating state (ON).

Figure 5 is a flowchart showing the operation of a control device for a shutter device according to one embodiment of the present invention. The CPU 18b of the control device 18 first determines whether the breaker 30 in the cut-off state is energized or not, based on the presence or absence of power supplied from the power supply device 20 (step 501). If the breaker 30 is not energized, the flow returns to the beginning. If the breaker 30 is energized, the CPU 18b prohibits the lowering of the sheet curtain 12 (step 502). At this time, in Figure 4, the CPU 18b has not yet controlled the energization of the activation sensor 40, and the activation sensor 40 is not on.

In FIG. 5, next, the CPU 18b determines whether or not the "predetermined time T" (e.g., several tens of seconds to several minutes) has elapsed since the breaker 30 was energized based on the data of the "predetermined time T" stored in the memory 18c (step 503). If the "predetermined time T" has not elapsed, step 503 is repeated. If the "predetermined time T" has elapsed, the CPU 18b controls the energization of the activation sensor 40 and turns on the activation sensor 40 (step 504). After that, the CPU 18b releases the prohibition on lowering the sheet curtain 12 (step 505).

According to the embodiment shown in FIG. 5, when the breaker 30 in the cut-off state is energized (step 501), the CPU 18b does not turn on the activation sensor 40, and after a "predetermined time T" has elapsed (step 503), the activation sensor 40 is turned on (step 504). This ensures time for the operator who energized the breaker 30 in the cut-off state to evacuate from the vicinity of the opening, and prevents malfunction of the sheet curtain 12 caused by an operator who was near the opening when the breaker 30 in the cut-off state was energized.

In addition, when the breaker 30 in the cut-off state is energized, the CPU 18b does not turn on the activation sensor 40 and prohibits the lowering of the sheet curtain 12 (step 502), and after turning on the activation sensor 40 (step 504), it releases the prohibition on the lowering of the sheet curtain 12 (step 505). Therefore, while the activation sensor 40 is not operating, the sheet curtain 12 is not lowered, ensuring safety.

Figure 6 is a flowchart showing the operation of a control device for a shutter device according to another embodiment of the present invention. In this embodiment, the stop button 19B of the operation switch 19 is used as an instruction means for the operator to instruct the control device 18 to turn on the activation sensor 40.

Steps 601-602 in FIG. 6 are similar to steps 501-502 in FIG.
After prohibiting the lowering of the sheet curtain 12 in step 602 in FIG. 6, the CPU 18b of the control device 18 judges whether the stop button 19B of the operation switch 19 has been operated (step 603). If the stop button 19B has not been operated, the CPU 18b judges whether the "first predetermined time T1" (e.g., several tens of seconds to several minutes) has elapsed since the breaker 30 was energized based on the data of the "first predetermined time T1" stored in the memory 18c (step 604). If the "first predetermined time T1" has not elapsed, the process returns to step 603. If the "first predetermined time T1" has elapsed, the CPU 18b controls the energization of the activation sensor 40 to turn on the activation sensor 40 (step 606). After that, the CPU 18b releases the prohibition of the lowering of the sheet curtain 12 (step 607).

When the stop button 19B is operated in step 603, the CPU 18b determines whether or not a "second predetermined time T2" (e.g., several tens of seconds) that is shorter than the "first predetermined time T1" has elapsed since the stop button 19B was operated, based on the data of the "second predetermined time T2" stored in the memory 18c (step 605). If the "second predetermined time T2" has not elapsed, step 605 is repeated. If the "second predetermined time T2" has elapsed, the CPU 18b controls the supply of electricity to the activation sensor 40, turning the activation sensor 40 on (step 606). After that, the CPU 18b releases the prohibition on lowering the sheet curtain 12 (step 607).

According to the embodiment shown in FIG. 6, after the breaker 30 in the cut-off state is energized (step 601), if the stop button 19B is not operated (step 603), the CPU 18b turns on the activation sensor 40 (step 606) after the “first predetermined time T1” has elapsed since the breaker 30 was energized (step 604). This allows the operator who energized the breaker 30 in the cut-off state enough time to evacuate from the vicinity of the opening.
Furthermore, when the stop button 19B is operated (step 603) after the breaker 30 in the cut-off state is energized (step 601), the CPU 18b turns on the activation sensor 40 (step 606) after a "second predetermined time T2" that is shorter than the "first predetermined time T1" has elapsed since the stop button 19B was operated (step 605). Therefore, when the operator who has energized the breaker 30 in the cut-off state is ready to retreat from around the opening, he or she can operate the stop button 19B of the operation switch 19 to hasten the time at which the activation sensor 40 is turned on.

In addition, the stop button 19B of the operation switch 19 also serves as an instruction means for instructing the control device 18 to turn on the activation sensor 40, so there is no need to provide an instruction means separate from the operation switch, and equipment costs do not increase.

Furthermore, when the breaker 30 in the cut-off state is energized (step 601), the CPU 18b does not turn on the activation sensor 40 and prohibits the lowering of the sheet curtain 12 (step 602), and after turning on the activation sensor 40 (step 606), it releases the prohibition on the lowering of the sheet curtain 12 (step 607). Therefore, while the activation sensor 40 is not operating, the sheet curtain 12 is not lowered, ensuring safety.

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.
