The container supporting member 16 protrudes forward from the main body 2 and is vertically movable upward and downward to move up and down when the mixing container 4 is coupled to the main body 2, And is lowered when the mixing vessel 4 is detached. The main body 2 is provided with a lever 18 for moving the container supporting member 16 up and down. The lever 18 and the container supporting member 16 are engaged so that the container supporting member 16 is lifted and lowered when the lever 18 is lifted upward and the container supporting member 16 is lifted Descend.

A method of operating a mortar mixing apparatus according to an embodiment of the present invention will now be described.

4 is a flowchart showing a mixing method of a paste according to an embodiment of the present invention. 5A and 5B are flowcharts illustrating a method of mixing mortars according to an embodiment of the present invention.

First, with reference to FIG. 4, a mixing method of a paste in which water and cement are mixed will be described.

The operator inserts water and cement into the mixing vessel 4 (S1). At this time, the operator inputs water and cement at a predetermined set ratio. Water and cement are put into the mixing vessel (4), and wait for about 30 seconds so that the cement is sufficiently absorbed in the water.

The operator then joins the mixing container 4 to the main body 2 and then operates the lever 18 to fix the lower portion of the mixing container 4 to the container supporting member 16. [ When the container supporting member 16 fixes the lower portion of the mixing container 4, the mixing container 4 can be prevented from oscillating or departing in the mixing container 4 when the paddle 8 rotates. When the mixing and fixing of the mixing vessel 4 is completed, the control unit 20 can notify that the coupling and fixing are completed through the display unit 14 (S2).

After confirming that the mixing vessel 4 is engaged and fixed, the operator selects the paste mixing mode using the operation unit 12 (S3).

When the paste mixing mode is selected, the controller 20 drives the motor 10 at a predetermined first rotation speed for a first predetermined operation time to rotate the paddle 8 at low speed (S4). In this embodiment, for example, the first operation time is about 60 seconds, and the first rotation speed is about 135 to 145 rpm, for example. In this case, when the paddle 8 is rotated at a high speed at the initial stage of mixing, the contact surface between the cement and water is condensed due to the hydraulic property of the cement, thereby lowering the cement absorption rate. Thereby maximizing the dispersion of the materials in the substrate 4.

On the other hand, it is determined whether or not the first operation time has elapsed (S5) while the motor 10 is rotating at the low rotation speed at the first rotation speed. When the first operation time has elapsed, The operation is stopped (S6).

When the motor 10 is stopped, the operator removes the mixing container 4 from the main body 2, and scrapes the mixed paste dispersed on the inner surface of the mixing container 4 to the center. To remove the mixing container 4, the lever 18 is operated to lower the container supporting member 16, and then the mixing container 4 is detached from the main body 2. Here, a scraper is used to scrape the mixed paste. After the mixed paste is scratched to the center of the mixing vessel 4, the mixing vessel 4 is again coupled to the main body 2 (S7).

On the other hand, when the motor 10 is stopped, the control unit 20 operates the lamp and the buzzer for the first stop time to notify the stop of the motor (S8). The first stop time is about 15 seconds, for example. The control unit 20 can make an alarm sound through the buzzer during the first stop time and control the lamp to blink. At this time, the controller 20 controls the flickering of the lamp slowly for 10 seconds from the stopping point, and then controls the flickering of the lamp rapidly for 5 seconds thereafter. Therefore, the operator can easily recognize the passage of time, so that it is possible to quickly perform the operation of raking the mixed paste and bonding the mixing container 4 to the main body 2. [

On the other hand, if it is determined that the first stop time has elapsed while the motor 10 is stopped (S9), if the mixing container 4 is coupled to the main body 2 after the first stop time has elapsed, The control unit 20 drives the motor 10 at the second rotation speed for the second operation time to rotate the paddle 8 at high speed. The second operation time is set to be longer than the first operation time, and is about 60 seconds, for example. The second rotation speed is set to be faster than the first rotation speed and is about 275 to 295 rpm, for example. By rotating the motor 10 at high speed in this way, air can be mixed into the material in the mixing container 4, and the mixture can be properly condensed (S10).

It is determined whether or not the second operation time has elapsed while the motor 10 rotates at a high rotation speed at the second rotation speed (S11). When the second operation time has elapsed, the control unit 20 stops the operation of the motor 10 (S12).

After the operation of the motor 10 is stopped, if the mixing container 4 is detached, it can be confirmed that the paste is completed in the mixing container 4 (S13).

As described above, by using the mixing device to produce a paste in which water and cement are mixed, sufficient and proper agitation can be performed, so that a good quality paste can be produced, and work time and manpower consumption can be minimized.

5A and 5B, a method of producing mortar by mixing the paste and sand produced as described above will be described.

The operator inserts the paste into the empty mixing container 4 (S20). Further, the operator inserts the required amount of sand into the hopper 6. [

After the worker has joined the mixing vessel 4 to the main body 2, the lever 18 is operated so that the vessel supporting member 16 fixes the lower portion of the mixing vessel 4. When the container supporting member 16 fixes the lower portion of the mixing container 4, the mixing container 4 can be prevented from oscillating or departing in the mixing container 4 when the paddle 8 rotates. When the mixing and fixing of the mixing vessel 4 is completed, the control unit 20 can notify that the coupling and fixing are completed through the display unit 14 (S21).

After confirming that the mixing vessel 4 is engaged and fixed, the operator selects the mortar mixing mode using the operation unit 12 (S22).

When the mortar mixing mode is selected, the control unit 20 drives the motor 10 at a third rotational speed set in advance for the third operation time to rotate the paddle 8 at a low speed (S23). In the present embodiment, for example, the third operation time is about 60 seconds, and the third rotation speed is about 135 to 145 rpm, for example. Here, the dispersion of the materials in the mixing vessel 4 can be maximized by rotating the paddle 8 at a low speed at the beginning of mixing.

While the motor 10 rotates at a low speed, the control unit 20 controls the operation of the valve 7 to inject sand into the mixing vessel 4 through the hopper 6. [ At this time, the sand throw-in time is after a predetermined set time has elapsed from when the motor 10 started to rotate at low speed. Here, the set time is about 30 seconds, for example. That is, when 30 seconds have elapsed since the motor 10 started to rotate at low speed, the valve 7 is opened to introduce sand into the mixing container 4 from the hopper 6 (S24) (S25).

It is determined whether or not the third operation time has elapsed while the motor 10 is rotating at the third rotation speed at the low rotation speed (S26). When the third operation time has elapsed, the control unit 20 sets the motor 10 in advance And drives the paddle 8 at a high speed during the fourth operation time at the fourth rotational speed. The fourth operation time is, for example, 60 seconds which is the same as the third operation time. The fourth rotational speed is set to be faster than the third rotational speed, and is about 275 to 295 rpm, for example (S27).

It is determined whether or not the fourth operation time has elapsed while the motor 10 is rotating at the fourth rotation speed at high speed (S28). When the fourth operation time has elapsed, the control unit 20 controls the operation of the motor 10 (S29)

When the motor 10 stops, the worker scrapes the mixed mixture to the center portion on the inner surface of the mixing container 4 after removing the mixing container 4 from the main body 2. To remove the mixing container 4, the lever 18 is operated to lower the container supporting member 16, and then the mixing container 4 is detached from the main body 2. A scraper is used to scrape the mixture. After the mixture is scratched to the center of the mixing vessel 4, the mixing vessel 4 is again coupled to the main body 2 (S30).

On the other hand, when the motor 10 is stopped, the control unit 20 operates the lamp and the buzzer for a second predetermined stop time to notify the stop of the motor (S31). The second stop time is about 90 seconds, for example. The control unit 20 can make an alarm sound through the buzzer for a second stop time and control the lamp to blink. At this time, the controller 20 controls the flickering of the lamp slowly for 80 seconds from the stopping point, and then, for 10 seconds, it can quickly control the flickering of the lamp. Therefore, the worker can easily recognize the passage of time, so that it is possible to perform the operation of raking the mixture and bonding the mixing vessel 4 to the body 2 quickly.

While the motor 10 is stopped, it is determined whether or not the second stop time has elapsed (S32). If the mixing container 4 is coupled to the main body 2 after the second stop time has elapsed, the control unit 20 drives the motor 10 at the fifth rotation speed for the fifth operation time, ) At a high speed. The fifth operation time is set to be the same as the fourth operation time, and is about 60 seconds, for example. The fifth rotation speed is set to be the same as the fourth rotation speed, and is about 275 to 295 rpm, for example (S33).

It is determined whether or not the fifth operation time has elapsed (S34) while the motor 10 is rotating at the fifth rotation speed at a high speed. If the fifth operation time has elapsed, the control unit 20 determines the operation of the motor 10 (S35).

After the operation of the motor 10 is stopped, if the mixing vessel 4 is detached, it can be confirmed that the mortar is completed in the mixing vessel 4 (S36).

As described above, by mixing and producing the mortar using the mixing device, sufficient and appropriate stirring is performed, so that good quality mortar can be produced. In addition, work time and manpower consumption can be minimized.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
