Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric winding device that winds and lowers an opening / closing member by a rotational driving force of a motor.

[0002]

2. Description of the Related Art A motor of a conventional electric winding device is wired at the time of factory shipment so as to rotate normally when the opening / closing member is wound, and reversely rotate when it is unwound. However, depending on the mounting location of the electric winding device, wiring may not be possible unless the direction of the motor is reversed. In such a case, it is necessary to reverse the rotation direction of the motor and re-wire the motor so that the motor rotates in the reverse direction when the opening / closing member is wound and rotates in the normal direction when the opening / closing member is unwound.

For this reason, conventionally, when the motor is installed in the left-right direction, the user / constructor pulls out the pin of the connector connecting the motor and the control device and replaces the pin in the reverse direction. The motor was rotating in the opposite direction. Alternatively, the lead wire between the motor and the connector is cut in advance at the manufacturing stage and shipped as a bare wire, and the user / constructor connects the lead wire according to the situation of the installation location of the electric winding device. Sometimes I did it.

[0004]

However, in the method of replacing the pins of the connector in the opposite direction, the pins are pulled out in a semi-forced manner, which may damage the connector or cause a contact failure, and thus the reliability of the connector is reduced. May be damaged. As a result, quality control and quality assurance cannot be thoroughly implemented, and the manufacturer cannot recommend such a method. Moreover, the user also has to perform extra work on the construction site in addition to the work of mounting the main body, which is very troublesome and inconvenient.

Also, the method of connecting the lead wires on site not only increases the labor on the construction site as in the above case, but may also make a mistake in the connection, which is also problematic in terms of reliability.

The present invention has been made in consideration of the above circumstances. Therefore, an object of the present invention is to easily switch the rotation direction of a motor according to the mounting direction of the motor and to improve the reliability of the product. It is to provide an electric winding device that can contribute to

[0007]

The electric winding device of the present invention winds and lowers the opening / closing member by the rotational driving force of the motor. In the winding of the opening / closing member, the motor is rotated in the forward direction to be lowered. It is characterized by further comprising operation mode switching means for switching between a first operation mode in which the motor is reversely rotated at a time and a second operation mode in which the motor is rotated in the reverse direction when the opening / closing member is wound up and is normally rotated when the opening / closing member is wound down.

[0008]

If the first operation mode is set by operating the operation mode switching means, the motor rotates normally when the opening / closing member is wound up and reversely rotates when it is unwound. On the other hand, if the operation mode switching means is operated to switch to the second operation mode, the motor rotates in the reverse direction when the opening / closing member is wound, and in the normal direction when the opening / closing member is unwound. Since the switching between the first operation mode and the second operation mode can be performed only by operating the operation mode switching means, connector replacement or lead wire connection according to the conventional motor mounting direction can be performed. No need for connection work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, as shown in FIG. 3, the motor 1 is arranged in the winding cylinder 2, and the rotation driving force of the motor 1 rotates the winding cylinder 2 so that the opening / closing member 3 is unwound or wound up. Is becoming On the other hand, the opening / closing member 3 is configured to be wound up and down by the winding cylinder 2 along the guide rail 4. A weight bar 5 is attached to the lower end of the opening / closing member 3 so that the opening / closing member 3 does not loosen during the hoisting and unwinding operations.

Further, as shown in FIG. 1, the motor 1 is composed of, for example, a capacitor motor, and its winding is connected to an AC power source 8 via semiconductor switching elements such as triacs 6 and 7. The control of forward / reverse rotation is controlled by turning on / off 7. In this case, if one of the triacs 6 is in the ON state, the motor 1
Rotates in the normal direction, and the motor 1 rotates in the reverse direction when the other triac 7 is in the ON state. The gates of the triacs 6 and 7 are connected to the microcomputer 9, and an on / off signal is input from the microcomputer 9 to the gates of the triacs 6 and 7.

The microcomputer 9 controls the operation of the motor 1 via the triacs 6 and 7 in response to an operation input from the operation unit 10. This microcomputer 9 has an operation mode switching means 11
Is set to either the first operation mode or the second operation mode. According to the control program shown in FIG. 2, in the first operation mode, the motor 1 is opened / closed. In the second operation mode, the motor 1 is rotated in the normal direction when it is wound up, and is rotated in the reverse direction when it is unwound.

In this case, when the motor 1 is attached to the left, for example, the operation mode switching means 11 is set to the first position.
When the motor 1 is set to the operation mode side and the motor 1 is installed in the left and right directions, the operation mode switching means 11 is set to the second operation mode side.

Next, the operation of the above configuration will be described.
When the user operates the operation unit 10 to wind up or down the opening / closing member 3, the microcomputer 5 controls the rotation of the motor 1 according to the control program shown in FIG.

That is, in step S1, whether the operation mode switching means 11 is set to the first operation mode side or the second operation mode side (that is, the direction of the motor 1 is reversed right and left). It is installed)). When the microcomputer 5 is set to the first operation mode side, the microcomputer 5 advances the following control operation in the first operation mode (step S2), and when it is set to the second operation mode side, Is advanced in the second operation mode (step S3).

First, when the control operation proceeds in the first operation mode, if there is an operation input from the operation unit 10 (YES in step S4), it is determined whether or not the operation input is a rising command (step S4). S5), if it is a rise command, a high level signal is output to one of the triacs 6, the triac 6 is turned on, and the motor 1 is rotated forward (step 6).

On the other hand, if it is a down command, the process proceeds from step S5 to step S7, a high level signal is output to the other triac 7, the triac 7 is turned on, and the motor 1 is rotated in the reverse direction. By such control, in the first operation mode, the motor 1 rotates normally when the opening / closing member 3 is wound up, and reversely rotates when it is unwound.

On the other hand, when the control operation proceeds in the second operation mode (that is, when the motor 1 is mounted in the left-right reversed direction), an operation input is input from the operation unit 10 (YES in step S8). Judgment), it is judged whether or not the operation input is a rising command (step S9), and if it is a rising command, a high level signal is output to the other triac 7, the triac 7 is turned on, and the motor 1 is reversed. Rotate (step 10).

On the other hand, if the command is a down command, the process proceeds from step S9 to step S11, a high level signal is output to one of the triacs 6, the triac 6 is turned on, and the motor 1 is rotated forward. By such control, in the second operation mode, the motor 1 rotates in the reverse direction when the opening / closing member 3 is wound up, and rotates in the forward direction when winding down.

As described above, the first operation mode in which the motor 1 is normally rotated when the opening / closing member 3 is wound up and is reversely rotated when being unwound, and the second operation mode where the motor 1 is reversely rotated when the opening / closing member 3 is wound up and normally rotated when unwinding. It is possible to freely switch between the operation modes and the operation mode switching means 11 by operating the operation mode switching means 11. Therefore, it is not necessary to replace the connector or connect the lead wire in accordance with the mounting direction of the motor 1, and the user side of the motor 1 is not required. This is convenient because it greatly reduces the time and effort required to change the rotation direction. Also, for the manufacturer side, the user side will not damage the connector or mistakenly connect the lead wires, so it will be possible to perform more thorough quality control and quality assurance of the product than before. The reliability can be improved. That is, providing the operation mode switching means 11 for switching between the first operation mode and the second operation mode is very beneficial to both the user side and the manufacturer side.

In this embodiment, the triacs 6 and 7 are used as the semiconductor switching device, but other than this, for example, a photothyristor is used, and it is changed to turn it on and off by irradiating light from the light emitting diode. Is also good.

Further, in the present embodiment, the switching operation between the first operation mode and the second operation mode is performed by software by the microcomputer 9, but this is performed by the IC.
Alternatively, the processing may be performed in a hardware manner by an electronic circuit using the above.

In addition, the present invention can be variously modified without departing from the scope of the invention, for example, a DC motor may be used instead of the capacitor motor.

[0023]

As is apparent from the above description, the present invention provides a first operation mode in which the motor is normally rotated when the opening / closing member is wound and reversely rotated when the opening / closing member is wound, and the motor is operated when the opening / closing member is wound. Since the operation mode switching means for switching between the second operation mode in which the motor is reversely rotated and normally rotated when unwinding is provided, the rotation direction of the motor can be easily switched according to the mounting direction of the motor, and at the same time, the product can be manufactured. Quality control and quality assurance can be thoroughly implemented, which can contribute to the improvement of product reliability.
