BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of an opening/closing device according to the present invention will be described below with reference to the accompanying drawings. In this embodiment, a shutter device having a shutter curtain that is opened and closed vertically as an opening/closing means will be described as an example. FIG. 1 is a diagram showing a schematic configuration of a shutter device, which is an opening/closing device according to one embodiment of the present invention. In FIG. 1, an opening/closing device 10 is a shutter device for vertically opening and closing an opening of a doorway.

The opening/closing body device 10 is provided at an opening of a building, and basically includes a shutter case 11, a shutter curtain 12, guide rails 13 and 14, a winding shaft 15, a chain 16, a motor 17, and a position detection device 172 ( 2), a control device 18, an obstacle sensor 185, an operation switch 19, a power supply device 20, and the like. Normally, the opening/closing device 10 drives a motor 17, which is an opening/closing device, according to the operation of the operation switch 19 to control opening/closing. Furthermore, in this opening/closing body device 10, the open state in which the shutter curtain 12 is wound around the winding shaft 15 is held by a mechanical holding mechanism (not shown). When an emergency signal BS or the like indicating the occurrence of the shutter is input to the control device 18, the holding mechanism is released from holding the open state, and the shutter curtain 12 naturally descends under its own weight to automatically close the opening. It also has the function to

The guide rails 13 and 14 are provided at both ends of the opening of the building so as to be in contact with both ends of the shutter curtain 12, and extend from the lintel to the floor and have a U-shaped cross section. It is composed of a metal member or a member equivalent to this. The shutter curtain 12 moves up and down along the guide grooves of the guide rails 13 and 14 to open and close the opening.

The winding shaft 15 is rotatably provided on both end sides of the shutter case 11 to wind up and rewind the shutter curtain 12 . The chain 16 connects a driving sprocket provided on the rotation shaft of the motor 17 and a driven sprocket provided on the rotation shaft of the winding shaft 15 . Therefore, the rotational driving force of the motor 17 is transmitted to the winding shaft 15 side via the chain 16, and when the motor 17 rotates, the winding shaft 15 rotates via the chain 16, and the shutter curtain 12 is opened and closed. It is supposed to be controlled.

The motor 17 is provided with a position detector 172 (see FIG. 2) for detecting its rotational position, that is, the open/closed position and open/closed state of the shutter curtain 12 . The position detection device 172 is composed of a pulse-generating rotary encoder or the like. Since a pulse signal corresponding to the rotation of the motor 17 is output to the control device 18, the rotational position of the motor 17 and the position of the closing side tip of the shutter curtain 12 at the opening can be controlled based on the generation of this pulse. The device 18 will calculate it.

Further, the position detection device 172 detects that the lower end of the shutter curtain 12 has reached the upper limit position for winding, and also detects that the lower end of the shutter curtain 12 has reached the lower limit position for rewinding. It also serves as an upper and lower limit switch.

The operation switch 19 has a rise (open) button 19A, a stop (stop) button 19B, and a fall (close) button 19C as control switches corresponding to each operation of opening and closing. It outputs the control signal to the control device 18 . Although not shown in FIG. 1, the control device 18 can also be operated by a wireless remote controller.

The emergency signal BS is a signal with a voltage of 24 [V] supplied from an external control room or the like in the event of an emergency such as a fire, and is input to a non-illustrated harm prevention interlock relay in the control device 18 . Along with the input of the emergency signal BS from the outside, or instead, a temperature sensor or the like is provided inside the shutter case 11 and near the opening of the lintel, that is, the part where the shutter curtain 12 moves up and down. may As this temperature sensor, the contact is always on, and when the contact reaches a predetermined temperature (an arbitrary temperature in the range of 100 to 300 degrees Celsius), the contact opens and turns off. It may be composed of a high-temperature bimetal type thermostat or the like, and may output a signal indicating that a fire or the like has occurred as a signal corresponding to the emergency signal BS when the contact is opened.

The obstacle sensor 185 has a transmitter provided at the lower end (seat plate) of the shutter curtain 12. When an obstacle is detected, a detection signal corresponding to the movement of the built-in seat plate switch is sent to the controller 18. In addition, when the seat plate switch returns after removing the obstacle, a return signal is transmitted. The transmission of signals from the transmitter of the obstacle sensor 185 to the control device 18 is not limited to the wired system as shown in the drawing, but may be a wireless system using a battery as a power source. A seat plate switch is provided at the lower end of the shutter curtain 12 to move upon contact with an obstacle, and a tape switch is provided along the height direction of the guide rails 13 and 14 by the moving force of the seat plate upon contact with the obstacle. or a configuration in which a sensing signal is output from the tape switch to the control device 18 by wire. In addition, a light emitting/receiving sensor such as a phototube or an LED may be provided in the opening, and an obstacle may be sensed in a non-contact manner by image recognition or the like.

The power supply device 20 is supplied with AC 100 V or AC 200 V power from the power supply line AC of the commercial power supply, and when there is no commercial power supply such as during a power failure, the external power supply 30 supplies AC with the same voltage as the commercial power supply. Power is supplied. As the external power supply 30, an electric vehicle, a hybrid vehicle, a portable backup AC power supply, or the like is used.

Since the switchgear device 10 is installed at and near an entrance, a window, or an opening such as an internal passage or space in a structure such as a house, a building, a factory, a warehouse, a garage, or the like, the electric vehicle can be used. vehicles can easily approach. Electric vehicles and the like are equipped with a battery and an inverter. The opening/closing operation of the opening/closing body can be easily performed at the time of power failure without using the
