3 is a side view when the flow measuring apparatus of FIG. 1 operates.

The present invention relates to a flow measuring apparatus and a flow measuring method using the same, and more particularly, to a flow measuring apparatus that can easily and accurately measure the flow of the liquid and a flow measuring method using the same.

If consumers use liquids such as rinses or shampoos, they prefer to spread over the hair. Therefore, when using a rinse or shampoo, it is important to measure the degree of spreading well on the hair. Flowability is used as an index indicating this.

Since it is difficult to directly measure the flowability, the flowability has been indirectly measured by using the viscosity (absolute viscosity) indicating the stickiness of the fluid. Viscosity is an indicator of the inherent viscous resistivity of the fluid itself, indicating the stickiness of the liquid against the liquid in the flowing state. Viscosity was measured using a Brookfield viscometer. However, the viscosity was somewhat different from the flow quality felt by the actual consumer. In other words, when measuring the viscosity of the rinse, but satisfies a certain level, there was a problem that the consumer does not spread well when using the rinse. Therefore, it was difficult to check whether the quality of the shampoo or rinse only reached the level satisfactory by the viscosity alone.

In order to solve the above problem, kinetic viscosity has been used as an index. Kinematic viscosity is a method of measuring the flowability of a fluid, that is, the fluidity, and is a relative index indicating the degree of fluid flow. Kinematic viscosity is the absolute viscosity divided by the density. Kinematic viscosity is used as an indicator of fluidity in circular tube flow or conduit fluid processes such as crude oil transport and oil viscosity. It is also used as an index for measuring the degree of coating or flowing of paint, paint, and the like.

Kinematic viscosity is measured mainly using an Oswalt viscometer. Oswald viscometer is mainly used in the laboratory as a method of measuring the time the fluid moves by dipping one end of the Oswald viscometer in a beaker containing the fluid and inhaled from the other end. In addition, the kinematic viscosity can be measured using an Ubbelohde viscometer and a cannon-fenske viscometer.

When measuring the kinematic viscosity by the above-described method, it is possible to measure the quality of the product actually used by the consumer, but the experiment takes a long time and cumbersome. Therefore, there was a problem that quality control is difficult during mass production.

The present invention is to solve the above-mentioned problems, to provide a flow measuring device that can easily and accurately measure the flow of the liquid.

In addition, the present invention is to provide a flow measurement method using the above-described flow measurement apparatus.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5D. These examples are merely illustrative of the present invention and the present invention is not limited thereto.

1 shows a flow measuring apparatus 100 according to an embodiment of the present invention. The structure of the flow measurement apparatus 100 shown in FIG. 1 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the flow measurement apparatus 100 may be modified in other forms.

The flow measurement apparatus 100 shown in FIG. 1 includes a reservoir 10, a switch 20, a detection sensor 30 (shown in FIG. 2), and a control panel 40. In addition, it may further include a base 50 for fixing them. Other parts may be further included as needed.

Since the base 50 has a stepped shape, the base 50 includes a base top 501 and a base bottom 503. In order to smoothly measure the flowability, the switch 20 is installed at the upper end of the base 501. The reservoir 10 is located on the bottom of the base 503, and the control panel 40 is installed on the bottom of the base 503. A sidewall 505 is formed between the upper end of the base 501 and the lower end of the base 503, and a sensor 30 (shown in FIG. 2) is installed therein to easily discharge the test object discharged from the reservoir 10. It can be detected.

The reservoir 10 stores the test subject. The test can be carried out by putting the test subject in the reservoir 10. The test subject is a liquid, and examples thereof include shampoo and rinse. It is preferable to form the reservoir 10 transparently so that the test subject stored in the reservoir 10 can be easily observed. The subject stored in the storage tank 10 is discharged downward by gravity. The space 101 is formed in the upper portion of the reservoir 10 to contain the test subject. Although FIG. 1 shows that three spaces 101 are formed in a cuboid 10, this is merely to illustrate the present invention, and the present invention is not limited thereto. Therefore, the storage tank 10 may be formed in the form of surrounding only three spaces 101, ie, three funnels.

The space 101 becomes smaller toward the bottom of the reservoir 10. As long as it becomes smaller toward the bottom, there is no great restriction on the shape of the space 101. The shape of the space 101 shown in FIG. 1 is for illustrating the present invention, and the present invention is not limited thereto. Since the space 101 has the above-described form, it is possible to smoothly discharge the subject under gravity by gravity. The support 60 fixes and supports the reservoir 10. The pedestal 70 is installed on both lower sides of the support 60 to fix the support 60 on the base 50.

Guide portions 103 are formed at both sides of the upper end of the reservoir 10. The guide part 103 extends long along the longitudinal direction of the reservoir 10. When the test subject is poured into the reservoir 10, the level between the test subjects stored in the three spaces 101 may not match. When the test subjects do not have the same level, the test subject is injected to slightly overflow the space 101 of the storage tank 10 during the test. Next, the upper surface of the reservoir 10 may be pushed in the + Y-axis direction by removing the contact plate 105 mounted on the base 50 to maintain the same level between the test subjects. Since the length of the contact plate 105 is the same as the width between the guide portions 103, the guide plate 103 can be guided to the guide portion 103 to stably remove the extra test subject.

As illustrated in FIG. 1, a plurality of spaces 101 may be formed to isolate and store a test subject. Therefore, various kinds of test subjects can be tested together. The space 101 is formed side by side along one direction (X-axis direction). The plate 105 preferably removes the test subject while passing all three spaces 101 at once. To this end, the guide part 103 extends in the direction (Y-axis direction) perpendicular to the direction (X-axis direction) in which the space 101 is formed side by side. Thus, the test subjects stored in the spaces 101 can be removed at once without being mixed with each other. The test subject thus removed may be removed by being contained in the temporary storage tank 107. To this end, the temporary storage tank 107 is detachably coupled to the upper end of the storage tank 10 at one end of the guide unit 103 and installed in the storage tank 10. Therefore, the extracted test subject can be easily separated and put in a temporary storage tank 107.

The switch 20 opens the lower portion of the reservoir 10 to discharge the test subject stored in the reservoir 10 to the lower portion or closes the lower portion of the reservoir 10 to block the discharge of the test subject to the lower portion.

The switch 20 includes a switch 201, a power transmission unit 203 and the drive unit 205. The opening and closing portion 201 includes a cylinder (not shown). The cylinder operates in the Y-axis direction and can be pneumatically operated by air supplied through line 2051. Since the structure of the cylinder can be easily understood by those skilled in the art, detailed description thereof will be omitted.

The power transmission unit 203 is connected to the driving unit 205 and moves forward and backward according to the operation of the cylinder. The power transmission portion 203 includes a piston rod 2031 (shown in FIG. 2), in which the piston rod 2031 inserted into the cylinder is advanced back and forth by pneumatic pressure. Power generated by the driving unit 205 is transmitted to the opening and closing unit 201 by the power transmission unit 203.

The opening and closing part 201 is connected to the power transmission part 203 and opens and closes to open and close the lower part of the reservoir 10. The guide hole 601 of the support 60 guides the forward and backward movement of the opening and closing portion 201 so that the opening and closing portion 201 can operate smoothly. As shown in FIG. 1, the opening and closing part 201 is installed in the same number as the number of the storage tanks 10. Since three storage tanks 10 are installed, three opening and closing portions 201 are also provided. Since the three opening and closing portions 201 are all connected to the power transmission portion 203, they move forward and backward at the same time. Therefore, the same type of test subject can be stored in the storage tank 10 so that the experiment can be carried out many times at the same time.

The control panel 40 is installed on the lower end of the base 503 to control the operation of the switch 20 and the detection sensor 30 and the like. The control panel 40 includes a MAIN POWER button 401, a timer 403, an ON button 405, an OFF button 407, and a RESET button 409. The power button 401 turns on or off the power of the flow measuring apparatus 100. When the power supply of the flow measurement apparatus 100 is in the ON state, when the ON button 405 is pressed, the switch 20 is operated and the reservoir 10 is opened to start discharging the test liquid to the lower portion. If the experiment is to be stopped in the middle, the experiment may be stopped by pressing the OFF button 407. The timer 403 may measure the kinematic viscosity of the test subject by measuring the time from the opening of the reservoir 10 to the initial detection of the test subject. In order to return the time recorded in the timer 403 to its original state, press the RESET button 409. Since the operation method of the control panel 40 can be easily understood by those skilled in the art, detailed description thereof will be omitted.

FIG. 2 shows a state of the flow measuring apparatus 100 of FIG. 1 seen from the left side. 2 shows the flow measurement apparatus 100 before it is still in operation.

As shown in FIG. 2, the reservoir 10 includes a storage 111 and a discharge 113. The subject 111 is stored in the storage 111. As the lower portion of the storage 111, the space for storing the test subject becomes smaller. The space 101 (shown in FIG. 1) in the storage 111 may be formed in an inverted cone shape, that is, a cone upside down for smooth discharge of the test subject. The discharge part 113 communicates with the lower end of the storage part 111 and passes through the support 60. The discharge part 113 extends downwardly so that a test subject may flow.

A pair of openings 1131 (dotted lines) are formed on the side surface of the discharge part 113. The opening and closing portion 201 is advanced back and forth through the pair of openings 1131. Therefore, the opening and closing part 201 may cross the discharge part 113 and penetrate the side surface thereof. Therefore, the discharge part 113 may be opened and closed using the opening and closing part 201. This will be described in more detail with reference to FIG. 2.

The enlarged circle of FIG. 2 shows a state where the storage unit 10 is viewed from the Z-axis direction when the flow measuring apparatus 100 does not operate. As shown in FIG. 2, the opening-and-closing part 201 is formed with the discharge opening 2011 (dotted line) which penetrated up and down. The discharge port 2011 communicates with the discharge part 113 to discharge the test subject downward. However, in FIG. 2, since the switch 20 is reversed and the discharge part 113 is blocked by the open / close part 201, the test object stored in the storage part 111 may not be discharged downward. Therefore, the test subject may be temporarily stored in the storage 111.

3 shows a state in which the flow measurement apparatus 100 shown in FIG. 2 operates. Since the switch 20 is operated as shown in FIG. 3, the switch 201 moves forward in the direction of the arrow. Since the opening and closing portion 201 is guided by the guide hole 601, it can be stably advanced, in which case the reservoir 10 is opened. 3 shows that the opening and closing portion 201 is advanced in the direction of the arrow, this is merely to illustrate the present invention and the present invention is not limited thereto. Therefore, when the position of the discharge port 2011 is changed, the opening and closing part 201 may be reversed.

As shown in the enlarged circle of FIG. 3, the opening of the reservoir 10 is performed while the discharge port 2011 of the switch 201 communicates with the discharge portion 113 of the reservoir 10. Therefore, the test subject stored in the storage 111 is discharged along the discharge 113.

The detection sensor 30 is provided on the side wall 505 of the base 50. When the reservoir 10 is opened, the detection sensor 30 detects the test subject discharged to the lower portion. To this end, the sensor 30 is spaced apart from the discharge part 113 of the storage unit 10 and is installed toward the discharge part 113. Therefore, the detection sensor 30 may detect the test object when it first arrives and transmit a signal to the control panel 40. As the detection sensor 30, a motion detection sensor or the like may be used, and other types of detection sensors may be used. The detailed structure of the sensing sensor may be easily understood by those skilled in the art, and thus the detailed description thereof will be omitted.

Hereinafter, an operation process of the flow measurement apparatus 10 will be described with reference to FIG. 4 and FIGS. 5A to 5D. 4 shows an operation flowchart of the flow measuring apparatus, and FIG. 5A to FIG. 5D schematically show an operation process of the flow measuring apparatus. For convenience, FIGS. 5A to 5D show only apparatuses related to flow measurement of a test subject. The operation process of the flow measurement apparatus 10 described later is merely to illustrate the present invention, the present invention is not limited thereto.

First, the experiment starts from step S400 of FIG. 5A shows the state before the experiment was started. The test subject L is filled in the storage 111 of the reservoir 10. Here, the test subject L has a constant viscosity as a rinse, a shampoo, or the like, and thus flows relatively slowly during the lower opening. Discharge of the test subject L is blocked by the opening / closing portion 201 penetrating the discharge portion 113. After storing the test subject L, the power button 401 of the control panel 40 is pressed. Therefore, the flow measuring device is turned on.

As the power is turned on, the sensor power is also turned on at step S410. Therefore, it is prepared to detect the test subject (L). Next, in step S420, the ON button 405 is pressed. In this case, the switch 20 is operated in the direction of the arrow in step S430 to advance the opening and closing portion 201 disposed in the lower portion of the reservoir 10. As the opening portion 201 is advanced, the discharge port 2011 of the opening portion 201 communicates with the discharge portion 113 of the storage tank 10. At the same time, the timer of the control panel 40 is automatically turned on in step S440 and the time starts counting in seconds. Therefore, the test subject L is discharged downward along the discharge part 113 in step S450.

In step S460, as illustrated in FIG. 5C, the test subject L first arrives at a sensing position of the sensing sensor 30. Therefore, the detection sensor 30 detects the test subject L and transmits a signal to the control panel. In step S470, the timer, in which the time continues to be counted by the signal transmitted by the sensor 30, is stopped. Therefore, the timer displays the time measured from the opening of the reservoir to the initial detection of the test subject L, that is, the time the test subject flowed. When the height difference from the lower height of the test subject L to the sensing sensor 30 at the time of blocking by the switchgear 20 is set height, the flowability of the liquid is calculated according to the following equation (1). The set height is fixed.

Flowability (mm / s) = set height (mm) / time the subject has flowed (s)

Through the above Equation 1, the flowability of the test subject can be easily obtained. Since the flowability is inversely proportional to the flow time of the test subject, the faster the test subject flows, the larger the calculated value and the better the flowability.

As described above, when the detection sensor 30 detects the test subject L, when the OFF button 407 is pressed as shown in FIG. 5D in step S480, the switch 20 moves backward in the direction of the arrow and returns to the original state. Return to. Accordingly, the lower portion of the reservoir 10 may be closed to block the flow of the test subject L. FIG. The test subject L discharged from the discharge part 113 of the storage tank 10 is discharged downward. Through all these processes, the experiment using the flow measurement apparatus is completed in step S490.

Since the flow measuring apparatus according to the present invention has a simple structure, it is possible to measure the kinematic viscosity of the test subject at low cost without fear of failure. In addition, the kinematic viscosity can be easily measured within a short time.

The flowability measuring apparatus according to the present invention has an advantage of automating the measurement by removing the factor of occurrence of deviation between the measurers.

According to the flowability measuring method of the present invention, the method of relying on sensory evaluation by conventional satisfaction measurement can be improved and quantified.

Although the present invention has been described above, it will be readily understood by those skilled in the art that various modifications and variations are possible without departing from the spirit and scope of the claims set out below.
