However, with such a configuration, usually, when the mounting portion 22 is lifted,
The torque of the motor 27 is set so that the weight including the iron body 21 and the mounting portion 22 can be raised at a sufficient speed. Therefore, when the mounting portion 22 is lowered, the weight of the iron body 21 and the mounting portion 22 is added to the force for lowering the mounting table 22 by the motor 27, so that an overload is applied to the driving portion of the mounting portion 22. In addition to
There was a problem that the noise of the motor 27 also increased.

If the voltage of the commercial AC power supply 25 fluctuates or the load of the motor 27 fluctuates, the voltage of the DC power supply 26 fluctuates, and the voltage applied to the motor driving means 28 changes accordingly. Therefore, there has been a problem that the rotation speed of the motor 27 fluctuates and the mounting portion 22 cannot always be moved at a constant speed.

Further, since the mounting table 22 is operated at a constant output, stress is applied to the driving device 24 at the time of starting and stopping the mounting table 22. Therefore, a heavy structure is required to obtain a strong structure that can withstand this for a long period of time. There was also the problem of becoming.

[0018]

An embodiment of the present invention will be described below with reference to FIG. The configuration of the iron main body and the mounting portion on which the iron main body is mounted is the same as the conventional example shown in FIG.

As shown in FIG. 1, a stand 1 includes a motor 2 for moving a mounting section (not shown) so as to be able to move up and down, a motor driving means 3 for driving the motor 2, and a motor driving means 3. Power control means 4 for supplying power, DC power supply 6 for converting an AC voltage of commercial AC power supply 5 to DC voltage and supplying the same to power control means 4, and signal generating means for generating a control signal for power control means 4 7 and a capacitor 8.

The motor driving means 3 controls the start, stop or rotation direction of the motor 2 when the mounting section is raised or lowered. The signal generating means 7 operates by the output of the motor driving means 3 when the motor driving means 3 drives the motor 2 in the direction of lowering the mounting portion, and sends a control signal such as a pulse to the power control means 4. Output. The power control means 4 is composed of a transistor, a thyristor and the like, and controls the voltage supplied to the motor 2 by the output of the signal generation means 7.

In the above configuration, the AC voltage of the commercial AC power supply 5 is converted into a DC voltage by the DC power
Is applied. When the mounting section is lowered, the power control means 4 is turned on / off intermittently by a signal from the signal generation means 7,
The voltage of the DC power supply 6 is sent to the motor driving means 3 by the signal generating means 7
Is applied intermittently according to the signal of Then, this voltage is intermittently applied to the motor 2 to rotate the motor 2 intermittently. Thus, the number of rotations of the motor 2 can be controlled at a low speed when lowering the mounting portion.

Next, a second embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. As shown in the figure, the voltage stabilizing means 9 stabilizes the voltage of the DC power supply 6 and makes the voltage applied to the motor 2 substantially constant.

The power supply voltage of the commercial AC power supply 6 is not constant, and the voltage of the DC power supply 6
It fluctuates due to the load fluctuation of the motor 2. Therefore, the voltage applied to the motor 2 also varies. Since the rotation speed of the motor 2 also depends on the applied voltage, the rotation speed of the motor 2 fluctuates due to the voltage fluctuation of the commercial AC power supply 5 and the load fluctuation of the motor 2.

In the above configuration, by providing the voltage stabilizing means 9, the voltage applied to the motor 2 is kept constant regardless of the voltage fluctuation of the commercial AC power supply 5 and the load fluctuation of the motor 2, and Can be kept constant.

Next, a third embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. As shown in the figure, the voltage detecting means 10 is connected to the motor driving means 3 to detect a voltage supplied to the motor driving means 3, and compares the output of the voltage detecting means 10 with the output of the reference voltage source 11. And the output of the signal generator 7 is controlled by the output of the voltage comparator 12.

In the above configuration, the voltage applied to the motor driving means 3 is detected by the voltage detecting means 10 and compared with the voltage of the reference voltage source 11 by the voltage comparing means 12. The voltage applied to the motor driving means 3 is changed by the voltage fluctuation of the commercial AC power supply 5 or the DC power supply 6
When the voltage fluctuates due to the voltage fluctuation, the difference between the voltage applied to the motor driving means 3 and the voltage of the reference voltage source 11 is sent to the signal generating means 7 as an output signal of the voltage comparing means 12.

The signal generating means 7 changes the signal sent to the power control means 4 according to the output signal of the voltage comparing means 12 so that the rotation speed of the motor 2 does not fluctuate. For example, when the voltage of the commercial AC power supply 5 decreases and the voltage applied to the motor driving means 3 decreases, the output signal of the signal generating means 7 is changed so that the power control means 4 is turned on for a longer time. As a result, the time during which the voltage is applied to the motor 2 is extended, and the rotation speed of the motor 2 can be kept constant.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. As shown in the figure, the timer unit 13 measures the passage of time,
The output of the signal generating means 7 is controlled by the output of the timer section 13.

In the above configuration, the signal output from the signal generating means 7 is changed by the timer means 13 as time passes. Thereby, the power control unit 4 is turned on /
The off time is changed as time passes, and the motor 2
, That is, the number of revolutions of the motor 2 can be changed over time. For example, it is possible to slow down the rotation of the mounting section just before the start and immediately before the stop, and to increase the rotation during that time. it can.

Next, a fifth embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. The position detecting means 14 is for detecting the position of the mounting portion. The position detecting means 14 is connected to the signal generating means 7 and
4, the output of the signal generating means 7 is controlled.

In the above configuration, when the receiver passes the position detecting means 14, the output signal of the signal generating means 7 is changed by the signal output from the position detecting means 14. Thereby, as described above, the rotation speed of the motor 2 can be changed before and after the passage of the position detection means 14, and for example, the rotation of the mounting portion is accelerated at the start of movement, and the position detection means 14 before the stop is stopped. After passing, the rotation can be slowed down until it stops. Needless to say, if a plurality of position detecting means 14 are provided, finer rotation control can be performed.
