Regarding the power conversion unit.

For example, as a device using an electric device such as a motor, an opening / closing body device will be described below as an example.
Opening and closing devices such as shutter curtains are installed at the entrances and windows of structural structures including buildings such as houses, buildings, factories, warehouses, and garages, or at openings such as internal passages and spaces, and open and close them. By moving the body, the opening is opened and closed. This opening / closing device includes a slat curtain made of a large number of strip-shaped slat materials, a pipe grill curtain made of a large number of pipe materials connected by a link material, and a panel curtain made of a single piece or a large number of connected panel materials. An opening / closing body such as 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 member of these is extended and lowered from the upper part of the opening to extend the entire opening. It is configured to close. In such an opening / closing body device, the opening / closing operation of the opening / closing body is often performed electrically. Examples of the electric opening / closing device include an electric shutter device, an electric door device, and an electric awning device.

Generally, in an electric switch, an switch for raising and closing a space for opening and closing a structure such as a building is driven up and down by a switch (motor, etc.) arranged behind the ceiling of the structure or in a shutter case. It has become like. In such an electric opening / closing body device, for example, there is a configuration in which the opening / closing body itself is lowered by its own weight and held in a fully closed state by performing a predetermined operation in the event of a power failure. Therefore, conventionally, when opening the fully closed opening / closing body in the event of a power failure, for example, the output rotating shaft (rotating shaft) of the switch is manually opened / closed by rotating it with a manual operation handle provided in the vicinity thereof. I was trying to roll up my body and open it.

In such an electric opening / closing device, even in the event of a power outage due to a fire, the opening / closing device is electrically operated by connecting the hose of the fire brigade to the water supply port (water supply port) and discharging water (water supply). Some are equipped with an emergency power supply that is configured to open the opening and closing body in an emergency. The emergency power supply unit is configured by mounting a standby power supply including a battery and electronic components such as an inverter device. External devices such as an automatic closing device for an opening / closing device, an obstacle detection device, an interlocking repeater for hazard prevention, an operation switch equipped with a start button, and a hydraulic switch, and an external power supply line are connected to this emergency power supply device. There is. As an opening / closing device provided with such an emergency power supply device, the one described in Patent Document 1 is known. In addition, there is also one that uses a generator to supply electric power to a control device of a switch (motor, etc.) in the event of a power failure of a commercial power source.

Hereinafter, preferred embodiments of the emergency external power conversion unit according to the present invention will be described with reference to the accompanying drawings. In this embodiment, an emergency external power conversion unit for a shutter device provided with a shutter curtain that opens and closes up and down as an opening / closing means will be described as an example. FIG. 1 is a diagram showing an example of a schematic configuration of a shutter device which is an opening / closing body device. In FIG. 1, the opening / closing body device 10 is a shutter device that opens / closes an opening at an entrance / exit up and down.

The opening / closing device 10 is provided at an opening of a building, and is basically a shutter case 11, a shutter curtain 12, guide rails 13, 14, a take-up shaft 15, a chain 16, a motor 17, a position detecting device 172, and the like. It includes a control device 18, an obstacle detector 185, an operation switch 19, a power supply switching device 20, a connector 20a, an external power supply conversion device 30, and the like. Normally, the opening / closing body device 10 drives a motor 17 which is an opening / closing machine to control opening / closing in response to an operation of the operation switch 19. Further, in the opening / closing body device 10, the shutter curtain 12 is held in an open state in which the shutter curtain 12 is wound around the take-up shaft 15 by a mechanical holding mechanism (not shown), and in this open state, a fire is generated from the outside. When an emergency signal BS or the like indicating the occurrence is input to the control device 18, the holding of the open state by the holding mechanism is released, and the shutter curtain 12 naturally descends under its own weight to automatically close the opening. It also has a function to

The guide rails 13 and 14 are provided on both ends of the opening of the building so as to be in contact with both ends of the shutter curtain 12, and a guide groove having a U-shaped cross section extending from the forage portion to the floor surface is formed. It is composed of a metal member having a member or a member equivalent thereto. The shutter curtain 12 rises and falls along the guide grooves of the guide rails 13 and 14, and opens and closes the opening.

The take-up shaft 15 is rotatably provided on both end sides of the shutter case 11 to take up and rewind the shutter curtain 12. The chain 16 connects a main sprocket provided on the rotating shaft of the motor 17 and a driven sprocket provided on the rotating shaft of the take-up shaft 15. Therefore, the rotational driving force of the motor 17 is transmitted to the take-up shaft 15 side via the chain 16, and when the motor 17 rotates, the take-up shaft 15 rotates via the chain 16 and the shutter curtain 12 opens and closes. It is designed to be controlled.

The motor 17 is provided with a position detecting device 172 (see FIG. 2) for detecting the rotational position, that is, the open / closed position and the open / closed state of the shutter curtain 12. The position detection device 172 is composed of a pulse generation type 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 rotation position of the motor 17 and the position at the opening of the closed end of the shutter curtain 12 are controlled based on the generation status of this pulse. The device 18 will be calculated.

The control device 18 has a microcomputer configuration, and power is supplied from the power supply line AC via the power supply switching device 20.

It may be composed of a high temperature bimetal thermostat or the like, and when a contact is opened, a signal indicating that a fire or the like has occurred may be output as a signal corresponding to an emergency signal BS.

The obstacle detector 185 has a transmitter provided at the lower end (seat plate) of the shutter curtain 12, and when an obstacle is detected, a detection signal corresponding to the movement of the built-in seat plate switch is transmitted to the control device 18. It is configured to transmit, and when the seat plate switch returns and moves due to the subsequent removal of obstacles, a return signal is transmitted. The transmission of the signal from the transmitter of the obstacle detector 185 to the control device 18 is not limited to the wired method as shown in the figure, but may be a wireless method operated by using a battery as a power source. Further, a seat plate switch that moves by contact with an obstacle is provided at the lower end of the shutter curtain 12, and a tape switch provided along the height direction of the guide rails 13 and 14 by the moving force of the seat plate at the time of contact with an obstacle. The detection signal may be output from the tape switch to the control device 18 by wire. In addition, a photocell or LED light emitting / receiving sensor may be provided in the opening to detect obstacles in a non-contact manner by image recognition or the like.

FIG. 2 is a diagram illustrating the operation of each device in the opening / closing body device.
