DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the accompanying drawings, which illustrate embodiments of the present invention in which a precision impeller RPM control is easy.

FIG. 1 and FIG. 2 are diagrams for illustrating a configuration of an agitation device that can easily control the RPM of a precision impeller according to a preferred embodiment of the present invention, and FIG. 3 is a diagram for explaining the RPM control of a precision impeller according to a preferred embodiment of the present invention 1 is a block diagram of a stirring device.

The present invention relates to an agitator including a motor and a stirring blade that rotates in conjunction with the motor, and a stirring blade that rotates in conjunction with the rotation shaft.

1 to 3, the stirring device which can easily control the RPM of a precision impeller according to the present invention includes a motor 30 for providing a rotating force, and an impeller shaft 51 for rotating together with the impeller 52 A decelerating gear 40 for rotating the output shaft with the decelerated RPM in association with the motor 30 according to a predetermined reduction ratio with respect to the RPM of the motor 30, A motor RPM sensor 60 for sensing the RPM of the motor 30 and a control unit 60 for controlling the RPM of the impeller 52 RPM control means 90 for controlling the motor output control unit 20 to control the motor output control unit 20 such that the output shaft RPM of the reduction gear 40 is generated according to the impeller RPM information set by the RPM control means 90, And a microcomputer 70 for controlling the microcomputer.

The impeller shaft 51 connected to the impeller 52, the motor output control unit 20, the motor RPM sensor 60, the RPM sensor 60, Adjustment means 90, and a microcomputer 70, and optionally further comprising a reduction gear 40.

The motor 30 is a means for providing a rotational force to the impeller shaft 51 in which the impeller 52 rotates in conjunction therewith. The motor 30 is connected to the motor output controller 20.

The motor output regulating unit 20 is a means for supplying power to the motor 30 and means for adjusting the RPM of the motor 30 by regulating the power supplied to the motor.

The reduction gear 40 includes an output shaft to which the impeller shaft 51 is coupled. The reduction gear 40 rotates the output shaft with the decelerated RPM in cooperation with the motor 30 according to a predetermined reduction ratio with respect to the RPM of the motor 30 It is means.

That is, the reduction gear 40 rotates the output shaft according to a predetermined reduction ratio with respect to the RPM of the motor 30.

At this time, the impeller shaft 51 is coupled to the output shaft, and the impeller 52 is coupled to the impeller shaft 51 to be engaged and rotated.

For example, when the reduction ratio is set by the reduction ratio setting unit 45 so that the reduction ratio of the output shaft of the reduction gear 40 is 2: 1, the RPM of the motor 30 is 200 RPM , The output shaft of the reduction gear 40 is rotated at 100 RPM.

The motor RPM sensor 60 is means for sensing the current RPM of the motor 30 in real time.

The RPM adjusting means 90 is a means for setting the RPM of the impeller 52 or the impeller shaft 51 or the output shaft to be rotated at a specific RPM.

That is, the RPM adjusting means 90 may be a dialing method, a digital input method, or the like, as the adjusting means for setting the rotational RPM of the impeller 52.

The RPM number of the impeller 52 set by the RPM adjusting means 90 can be displayed on the set RPM display portion 83 and the current RPM number of the impeller 52 can be displayed on the current RPM display portion 84 respectively.

An embodiment of the dialing method will be described in more detail later in this specification.

The microcomputer 70 is a means for controlling the motor output control unit 20 so that the output shaft RPM of the reduction gear 40 is generated according to the RPM information of the impeller 52 set by the RPM control means 90.

That is, the microcomputer 70 controls the motor output control unit 20 to generate the RPM of the motor, which allows the impeller to rotate according to the impeller RPM set by the RPM control unit 90, And power is supplied to the motor (30) from the output control unit (20).

At this time, the microcomputer 70 controls the RPM of the motor 30 to be controlled according to the reduction ratio of the reduction gear 40.

For example, as in the above example, the reduction ratio of the reduction gear 40 is set by the reduction gear setting unit 45 so that the RPM of the motor 30 is 2: 1, The microcomputer 70 controls the operation of the motor output regulator 20 such that the RPM of the motor 30 becomes 200 RPM when the impeller 52 is set to rotate at 100 RPM at 90 RPM.

FIG. 4 is a view illustrating an example in which the RPM adjusting means 90 is selected and operated in the first adjusting mode, and FIG. 5 is an example of the RPM adjusting means 90 being selected and operated in the second adjusting mode.

4 and 5, the RPM regulating means 90 may be operated in a first regulating mode and a second regulating mode, in which the pushing of the dial button 93 of the RPM regulating means 90 The second needle 87 is connected to the switch 85 by the second switch 87. [

The first control mode is a mode in which the RPM of the impeller 52 is precisely adjusted by a discontinuous first RPM variation amount within a range between the minimum RPM and the maximum RPM.

The second mode of adjustment may be such that the RPM of the impeller 52 is rapidly fluctuated by a constant, discontinuous second RPM change amount that is greater than the first RPM change amount within the range between the minimum RPM and the maximum RPM of the impeller 52 This mode is controlled.

For example, in the first adjustment mode, the impeller RPM may be set to be changed by 10 RPM per unit rotation angle of the dial button 93, and in the second adjustment mode, the impeller RPM May be set to change by 50 RPM.

Alternatively, the first RPM change amount in the first control mode may be set to 1 RPM and the second RPM change amount in the second control mode may be set to be 20 RPM.

That is, the RPM of the impeller 52 can be precisely controlled in the first adjustment mode, and the RPM of the impeller 52 can be rapidly and variably controlled in the second adjustment mode.

In general, the stirring speed may be precisely maintained within a certain range, or it may be necessary to adjust the stirring speed slowly so that the stirring speed can be finely controlled in the first adjusting mode without depressing the dial button 93.

On the other hand, when stirring is to be started at a high RPM, when it is necessary to change the stirring speed rapidly according to the phase change of the stirring object during stirring, when it is necessary to stir for a short time, The stirring speed can be quickly and variably controlled in the second control mode while being held down.

6 is a flowchart illustrating a method of controlling the RPM control means 90 according to an embodiment of the present invention in which the first control mode and the second control mode are selected in accordance with the depression of the dial button 93 of the RPM control means 90 and the RPM is selected according to the rotation amount of the dial button 93 The present RPM adjustment means 90 includes a dial button 93, a first needle 86, a second needle 87, a tab 96, a wire 97, Lt; / RTI > 7 is a plan view showing the arrangement of the first needle 86, the tab 96 and the electric wire 97 with the RPM adjusting means 90 being selected in the first adjustment mode, Is a plan view for showing the arrangement of the first needle (86), the tab (96), and the electric wire (97) with the means (90) selected in the second adjustment mode.

The RPM control means 90 of the present invention determines whether or not the set RPM of the tap 96 to which the first needle 86 is connected becomes 0 while the power is ON and the RPM change amount There is no reason why the number of RPMs to be displayed around the dial button 93 is displayed in advance because the setting RPM and the current RPM are differently displayed on the display units 83 and 84. However, 4, 5, 7, and 8, the number of RPMs corresponding to the amount of RPM change for each tab 96 is shown.

Referring to FIG. 6, a first needle 86 and a second needle 87 are extended from the dial button 93 of the RPM adjusting means 90.

The first needle 86 can be electrically discontinuously connected to the tabs 96 disposed along a constant circumference about the dial button 93 in accordance with the rotation of the dial button 93, And the resistance value measured by the resistance measuring device (not shown) can be grasped by the microcomputer 70. [0052] Fig.

Each of the tabs 96 is connected to an electric wire 97 having a different resistance value and each electric wire 97 is connected to a resistance meter (not shown) connected to the microcomputer 70, The intrinsic resistance value may be designed to be input to the microcomputer 70 in advance.

The position of the tab 96 to which the first needle 86 is currently connected can be grasped by the microcomputer 70 through the resistance value measured by the resistance meter (not shown) The rotation direction and the amount of rotation (angle) can be grasped by the microcomputer 70 when the first needle 87 rotates in accordance with the rotation of the first needle 87.

On the other hand, when the dial button 93 is pressed, the second needle 87 is electrically connected to the switch 85 so that a current flows to the microcomputer 70, whereby the microcomputer 70 can grasp the control mode.

It is preferable that the RPM adjusting means 90 is basically selected to be in the first adjusting mode 91 and is designed to be operated in the second adjusting mode 92 in a state in which the switch 85, which will be described later, Do.

The microcomputer 70 recognizes the state in which the second needle 87 and the switch 85 are separated from each other and turned off by the switch 85 because the dial button 93 of the RPM adjusting means 90 is not pressed, When the dial 93 is pressed and the second needle 87 and the switch 85 are electrically connected and turned on, an electrical signal flows to the microcomputer 70 so that the microcomputer 70 recognizes it as the second adjustment mode . &Lt; / RTI >

The first RPM change amount in the first control mode and the second RPM change amount in the second control mode can be input to the microcomputer 70 in advance.

The RPM setting in the first mode adjustment and the second adjustment mode is set by the rotation amount (angle) of the dial button 93 of the RPM adjustment means.

For example, if the dial button 93 of the RPM control means 90 is rotated in the clockwise direction without being pressed, the microcomputer 70 controls the motor output control unit 20 so that the RPM increases by the first RPM change amount at every predetermined angle can do.

For example, when the dial button 93 of the RPM control means 90 is rotated in the counterclockwise direction without depressing the dial button 93, the microcomputer 70 controls the motor output control unit 20 such that RPM decreases by the first RPM change amount Can be controlled.

For example, when the dial button 93 of the RPM control means 90 is pressed and rotated in the clockwise direction, the microcomputer 70 controls the motor output control unit 20 such that RPM increases by a second RPM change amount at a certain angle .

For example, when the dial button 93 of the RPM control means 90 is pressed and rotated in the counterclockwise direction, the microcomputer 70 controls the motor output control unit 20 such that the RPM is decreased by the first RPM change amount at every predetermined angle can do.

4 and 7 illustrate operation of the RPM adjusting means in the first adjustment mode. In FIG. 4 and FIG. 7, clocks are generated at a predetermined angle of about 9 degrees from 0 RPM, which is the reference position of the first needle 86, The RPM is set to be increased by 10 RPM, which is the first RPM change amount.

In the case of the conventional RPM adjusting means, when the power is turned off while the first needle 86 of the dial button 93 is adjusted to the high RPM, when the power is turned on to resume the operation of the stirrer, The reference position of the first needle 86 in the power ON state in the first adjustment mode is set to be lower than the reference position of the first needle 86 in the power ON state even when the power is turned off at the high RPM Starting from 0 RPM, this problem can be solved.

Also, unlike the conventional RPM control means, the present RPM control means 90 can rotate several times over 360 degrees, which makes it possible to precisely control the RPM within a wider RPM range than the conventional RPM control means It becomes.

5 and 8 illustrate the operation of the RPM adjusting means in the second adjusting mode. In this case, the RPM adjusting means is operated from the specific RPM, which is the reference position of the first needle 86 in the pressed state of the dial button 93, Is set to increase by 20 RPM, which is a second RPM change amount, which is larger than the first RPM change amount, every time the rotation is made by 9 degrees in the clockwise direction.

In this case, when the RPM adjusting means 90 is rotated in the counterclockwise direction, the operation principle is set such that the RPM is adjusted to be decreased by the second RPM change amount at every predetermined angle. The operation principle is the same as that in the operation state by the first mode adjustment Principle can be set.

The microcomputer 70 is connected to the motor RPM sensor 60 and receives RPM information of the motor 30 in real time and compares the RPM information with the impeller RPM information set by the RPM control means 90, When the RPM information of the impeller calculated corresponding to the received RPM information of the motor 30 is out of the preset tolerance range from the impeller RPM information set by the RPM adjusting means 90, And precisely and quickly controls the operation of the motor output regulating part 20 so as to be formed within the tolerance range.
