Description

The present invention relates to a measurement method for classifying a brush and a standard matrix diagram of the method, and particularly provides a standardization of a brush for performing a measurement method for classification and a standard matrix diagram.

All the brushes produced on the market are handmade by hand brush craftsmen. Manufacture is purely based on the experience of the individual brush craftsman, and there is currently no standardized standard. Therefore, even if a brush with the same design is produced by the same brush craftsman, there will be a difference in the properties of the brush. Therefore, when brushmakers with different experiences produce brushes of the same design, the difference in brush quality becomes even more apparent.

As mentioned above, the current brush manufacturing method clearly shows the difference in brush quality. So when buying a brush, especially brush lovers like calligraphers and ink painters, you can find one of the hundreds of brushes that suits you, but next time you buy the same brush. Sometimes, even if the brushes have the same display, the problem is that they are not all the same. For this reason, there is a problem that the brush does not fit in the hand when writing a book, and the brush is repurchased, and there is no basis for choosing the brush. Therefore, how to solve the problem that the current brush is not standardized is the problem to be solved by the present invention.

In order to improve the above-mentioned problems, the present invention provides a standard measurement of the ear neck, and a measurement method for brush classification and a standard matrix diagram of the method as a basis for brush classification.

It includes the following steps: The root of the ear is connected to the ear mounting rod, the ear neck installation rod is fixed on the detector stand at the reproduction angle, and the spike is directed toward the pressure sensor member installed on the detector stand, and the detector stand is used. Drives the tip installation rod to advance the route of downward pressing to reproduce the brush stroke, presses the tip against the pressure sensor member until it is elastically curved, and displaces it, and repeats this multiple times. When the average value is taken from the acquired multiple pressure values, the actual pressure value is measured, and the actual pressure value is compared with the standard matrix diagram and matched with the comparative pressure value, the head of the ear belongs to the matching comparative pressure value. It is the diameter, the length of the spikes and the corresponding brush hardness.

As another embodiment of the present invention, a standard matrix diagram using a measurement method for brush classification is provided. It divides into multiple spike diameters based on the size of the diameter of the ear root of the brush to be classified, and divides the lengths of multiple spikes within each spike diameter, and within each spike length. Further, a plurality of brush hardnesses are classified, and a standard matrix diagram is created with a plurality of brush hardnesses corresponding to a plurality of spike diameters and a plurality of spike lengths. Any brush hardness within the length of each panicle corresponding to each panicle diameter in the standard matrix diagram all has corresponding comparative pressure values.

The measurement method for brush classification of the present invention and the standard matrix diagram of the method measure the actual pressure value corresponding to each ear, and when classifying the brush, the standard to which the measurement method belongs based on the actual pressure value of each ear. Can be derived. By doing this, each ear has a standard to which it belongs, achieving standardization of brushes, making it easy for people to find a suitable standard when choosing a brush, and it is a basis for repurchasing a brush. There are advantages.

(One embodiment)
In order to explain the present invention, the central idea shown in the above-mentioned contents of the invention will be described with reference to specific examples. It is noted here that the various different members in the embodiment are ratios, sizes, deformations or displacements for illustration purposes, not actual member ratios.

The present invention provides a measurement method for brush classification and a standard matrix diagram of the method. First, the brushes classified in the following examples will be described. In FIGS. 1 and 2, the diameter of the 50 roots of the ear of the brush (hereinafter referred to as the ear diameter) is 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm. It is classified by 18 mm, 19 mm, 20 mm, and 21 mm, and is classified by the ear diameter A of 18 different ear diameters.
Further, each ear diameter A is further divided into a plurality of ear lengths B (the ear length B indicated by the present invention refers to the length of the brush ear after the root is subtracted from the ear 50). .. Each ear diameter A of this embodiment has three types of ear lengths B (unit: mm) of long hair, medium hair, and short hair, and in FIG. 1, the length of the ear root of each ear diameter A is further increased. Is shown.
Further, the length B of each ear is divided into a plurality of brush hardness C. In this embodiment, it is classified into three types of brush hardness C: bristles, standard hairs, and soft hairs.
Therefore, in the examples described below, the brushes that can be classified have 18 kinds of ear diameters A, each ear diameter A has 3 kinds of ear lengths B, and each ear length B has each ear length B. Since each of them has three types of brush hardness C, it can be classified into 162 types of brushes of different standards in this embodiment. However, the standards and quantities for the classification of brushes described here are merely for explaining this embodiment, and are not limited to the above-mentioned 162 types of standards.

In this embodiment, the measuring method is based on the above-mentioned 162 types of standards classified by brush, and first, a standard matrix diagram 100 (see FIG. 2) for brush classification is created. Based on the size of the diameter of the root of the ear 50 of the brush to be classified (4 mm to 21 mm), 18 kinds of ear diameters A are classified, and the ear diameters A are shown in the header of the vertical column in FIG.
Within each ear diameter A, the above-mentioned long hair, medium hair, and short hair are divided into ear lengths B, and further, within each ear length B, the above-mentioned bristles, standard hairs, and soft hairs are brushed. It is classified into hardness C. The length B of these spikes and the corresponding brush hardness C are shown in the header of the row in FIG. Based on these, in this embodiment, 162 kinds of standard matrix diagrams 100 are created.

In the standard matrix FIG. 100 shown in FIG. 2, any brush hardness C among the length B of each panicle corresponding to each panicle diameter A has a comparative pressure value D corresponding to each other. When classifying brushes, the head of each brush is based on the diameter A and the length B of the brush to which it belongs, and then the comparative pressure value D corresponding to each brush hardness C in the standard matrix diagram 100 is used as a comparison standard. Refer to them and classify the brushes based on them.

Further, in the standard matrix FIG. 100 shown in FIG. 2, among the three types of ear lengths B such as long hair, middle hair, and short hair classified by each ear diameter A, the ear length B is included in the “middle hair”. The comparative pressure value D of any brush hardness C is 1.16 times the comparative pressure value D of the same brush hardness C among the "long hairs" whose ear length B within the same ear diameter A is "long hair". (Here, it is defined as the first constant multiple).
The comparative pressure value D of any brush hardness C when the ear length B is "short hair" is the same brush hardness when the ear length B is "medium hair" within the same ear diameter A. The comparative pressure value D of C is 1.16 times. To explain by way of example, the corresponding comparative pressure values in which the ear diameter A is the same for the ear neck having a diameter of 5 mm, the ear length B is "medium hair", and the brush hardness C is "standard hair". D "25 g" is 1.16 times (rounded to an integer value) the corresponding comparative pressure value D "22 g" having a spike length B of "long hair" and the same brush hardness C.
Similarly, the ear diameter A is a tip with a diameter of 5 mm, and the corresponding comparative pressure value D "29 g" in which the ear length B is "short hair" and the brush hardness C is "standard hair" is The ear length B is "medium hair" and 1.16 times the corresponding comparative pressure value D "25 g" of the same brush hardness C, and the calculation of other ear diameters A follows this.

As described above, in the standard matrix FIG. 100 shown in FIG. 2, the length B of each ear is classified into three types of brush hardness C such as bristles, standard hairs, and soft hairs. Of the brush hardness C belonging to any ear length B, the comparative pressure value D of "standard hair" is 1.3 times the comparative pressure value D of "bristle" (here, the second constant times). The comparative pressure value D of "bristle" is 1.3 times the comparative pressure value D of "standard hair". To explain by way of example, the ear diameter A is the same at a diameter of 5 mm, and the ear length B is the head of "middle hair". The comparative pressure value D "25 g" whose brush hardness C is "standard hair" is 1.3 times the comparative pressure value D "19 g" whose brush hardness C is "soft hair" (rounded to an integer value). To).
Similarly, the comparative pressure value D "33 g" in which the ear diameter A is 5 mm in diameter, the ear length B is the "middle hair" head, and the brush hardness C is "bristle" is the brush hair. The hardness C is 1.3 times the comparative pressure value D "25 g" of the "standard hair", and the other calculations for the ear diameter A and the ear length B follow this. The above-mentioned first constant times and second constant times are 1.16 times the corresponding spike length B and 1.3 times the corresponding brush hardness C, and are also used for many years of repeated verification. I got a good result. However, the present invention does not limit this. As an example, the first constant multiple or the second constant multiple may all be adjusted within the range of 1.1 to 1.5 times.

As described above, each panicle A is all acquired at the comparative pressure values D of different panicle lengths B and corresponding brush hardness C, such as the first and second constant times described above. .. Therefore, when the present embodiment creates the standard matrix diagram 100 of FIG. 2, in the ear diameter A of 18 kinds of ear diameters (4 mm to 21 mm), the present invention has the ear diameters A of 5 mm, 11 mm and 17 mm. , The comparative pressure value D of the ear length B is "medium hair" and the brush hardness C is "standard hair" is empirically measured, and then all the ear diameters of 4 mm to 21 mm are measured by the average sharing method. The comparative pressure value D of A is established. The comparative pressure value D corresponding to the spike diameter A from large to small decreases by the method from high to low, and further, based on the above-mentioned first constant multiple and second constant multiple, all the spike lengths by the above method. The comparative pressure value D of the corresponding brush hardness C of B is calculated.

5 to 6 show an apparatus to which the measuring method of brush classification is applied, and in this embodiment, the calibration table 10, the detector table 20, and the electronic control unit 30 are included.
As shown in FIG. 5, a calibration head 11 is provided on the calibration table 10, and one end of the calibration head 11 has an acute-angled shape. In this embodiment, the calibration head 11 is installed above the calibration table 10 and one end of the acute-angled shape. Is facing down.
As shown in FIG. 6, the detector base 20 includes the base 21, the holding device 22, and the pressure sensor member 23 in this embodiment. The sandwiching device 22 includes a moving member 221 and a localization table 222, and the moving member 221 is installed on the base 21 and connects the driving member 24. The localization table 222 is installed on the moving member 221. Both the pressure sensor member 23 and the driving member 24 are electrically connected to the electronic control unit 30, and the driving member 24 is controlled by the electronic control unit 30 to displace the moving member 221. The standard matrix diagram 100 is digitized and stored in the electronic control unit 30, and the electronic control unit 30 has a display 31. The standard matrix diagram 100 may be digitized and stored in a terminal device (not shown in the diagram), for example, by storing it in a personal computer or a smartphone and displaying it, and this is used as a basis for classifying brushstrokes.
Further, the standard matrix diagram 100 may be an entity such as being displayed on paper or a board member. The pressure sensor member 23 is a load in this embodiment, the actual pressure value in this embodiment is a load measured by the pressure sensor member 23, and the above-mentioned comparative pressure value D is also displayed in units of g (gram). To.

In this embodiment, the base 21 is defined as the X-axis direction and the Y-axis direction intersecting horizontally, and the Z-axis direction is defined as vertically intersecting the X-axis direction and the Y-axis direction. The moving member 221 of this embodiment is moved by the driving member 24 and is displaced with respect to the base 21 along at least one axial direction in the X-axis direction, the Y-axis direction, and the Z-axis direction. The drive member 24 of this embodiment is a servomotor, and the moving member 221 is connected by a lead screw (not shown), and the localization table 222 is installed on the moving member 221 by a slide table and a slide rail (not shown). ..

The method for measuring the brush classification is as shown in FIG. 3 in the steps of this embodiment, and the details are as follows.

First, the root of the ear 50 waiting for measurement is connected to the ear installation rod 40 (step S1). The panicle mounting rod 40 is made of aluminum in this embodiment, and includes a holder body 41 and a head portion 42. The head portion 42 is installed at one end of the holder body 41, and then the root portion of the ear neck 50 is connected to the head portion 42 (see FIG. 4). The ear neck mounting rod 40 used in this embodiment is made of aluminum, but it is mainly composed of wood because the ear neck mounting rod 40 has an advantage that it is not affected by changes in the environment and has no size error. Prevents rods from causing size changes due to temperature or humidity.
In addition, the combination of the holder body 41 and the head portion 42 is only one holder body 41 in this embodiment, and the other 18 kinds of ear diameters A of this embodiment correspond to each other. The head portion 42 to be used is selected and used, and here, one head portion 42 is taken as an example.

When the step of connecting the root of the scion 50 to the panicle 40 is completed, the panicle 40 can be fixed on the detector stand 20 at a brush grip reproduction angle. In order to reproduce the movement of actually gripping the brush, the ear neck 50 can be brought closer to the actual brush stroke situation by first wetting it.
In this embodiment, before the tip of the tip 40 is fixed on the detector stand 20 at a brush grip reproduction angle, the tip of the tip 50 is wetted and the brushes are trimmed to form the tip of the tip 50 into an acute-angled shape. .. Next, the panicle installation rod 40 is localized on the calibration table 10 (see FIG. 5). At this time, when the ear neck 50 is made upright on the ear neck installation rod 40 and the end of the acute angle shape of the fixed ear neck 50 faces one end of the acute angle shape of the calibration head 11, and the acute angle and the acute angle face each other, Make sure that the sharp edges of the ear 50 are centered. The main advantage of the operation of confirming that the sharp end of the ear 50 is aligned with the center is that when the ear 50 is fixed to the detector stand 20 together with the ear mounting rod 40, the acute angle shape is obtained. Ensure that the end of the ear 50 does not deviate from the center and a measurement error does not occur.

After confirming that the sharp end of the ear 50 is aligned with the center, the ear mounting rod 40 can be fixed on the detector base 20 (see FIG. 6). Further, when the ear neck installation rod 40 is fixed, the brush grip reproduction angle is set, and the ear neck 50 faces the pressure sensor member 23 (step S2) installed on the detector base 20. In this embodiment, the ear neck installation rod 40 is fixed to the localization table 222, and when fixed, the brush grip reproduction angle is 12 degrees with respect to the vertical direction of the pressure sensor member 23, following the habit of copying by a person. And.

When fixing the panicle mounting rod 40 on the detector base 20 at a brush grip reproduction angle, it is necessary to set the route, displacement speed and process for the detector base 20 to displace the panicle mounting rod 40. The route is that the detector base 20 is installed on the ear neck in a situation where the ear neck installation rod 40 is fixed at the brush grip reproduction angle on the localization table 222 and is tilted at 12 degrees with respect to the vertical direction of the pressure sensor member 23. This is a route in which the 杆 40 is pressed downward to reproduce the brush stroke.
In this embodiment, the panicle mounting rod 40 is driven and displaced by a route inclined at 45 degrees with respect to the vertical direction of the pressure sensor member 23. The displacement speed is a speed at which the electronic control unit 30 controls the drive member 24 to displace the moving member 221. In this embodiment, the displacement speed is set at 50 cm / min, and the displacement speed is the speed at which a person writes with a brush. It is the speed that reproduces.

The process refers to the process required from when the ear neck 50 touches the pressure sensor member 23 to when it is elastically curved and displaced. Further, in this embodiment, the ear neck 50 is set to half the length exposed from the ear neck installation rod 40.
As an example, if the panicle A has a panicle 50 with a diameter of 10 mm, it has a panicle length B of "short hair" of 38.5 mm (see FIG. 1), that is, the panicle 50 has a root length of 7 mm. After subtraction, it is the length exposed from the panicle installation rod 40, and half the length is about 19 mm (rounded to an integer value). That is, the process required from when the ear neck 50 touches the pressure sensor member 23 to when it is elastically curved and displaced can be set to 19 mm. The other panicle diameters A are inferred to correspond to the processes required for each panicle length B.

If the ear neck 50 has a diameter of 12 mm and the ear length B is "middle hair", the process required for the displacement at the time of measurement is about half the length of the ear length B (53 mm). It is 27 mm (rounded to an integer value).
The tip of the tip 40 is fixed to the localization table 222 at a brush grip reproduction angle, and the preset path, process, and displacement speed of the tip 40 are displaced, that is, the pinching device 22 holds the tip 50 of the tip. Adjusts to the point where the pressure sensor member 23 touches a little (see FIG. 7A), then operates the electronic control unit 30 and displaces the moving member 221 by the drive member 24 (in the X-axis direction and the Z-axis direction). Displaces at an angle of 45 degrees along both axes). That is, the speeds match and proceed calmly. At this time, the ear neck 50 is a downward pressing route for brush grip reproduction angle and brush stroke reproduction, and is displaced by 27 mm from touching the pressure sensor member 23 until it becomes elastically curved (see FIG. 7 (B)). ) (Step S3). At this time, the measured actual pressure value is 116 g, and this actual pressure value is displayed on the display 31.
Next, it is compared whether or not the actual pressure value measured by the electronic control unit 30 and the comparative pressure value D in the above-mentioned standard matrix diagram 100 match (step S4). According to this comparison, when the ear neck 50 has a diameter of 12 mm and the ear length B is "middle hair", the actual pressure value of 116 g is the comparative pressure of the brush hardness C of "bristle" when looking at the standard matrix diagram 100. It can be seen that it corresponds to the value D (same thing 116 g). The ear 50 has an ear diameter A of 12 mm, which belongs to a comparative pressure value D of 116 g, an ear length B is "medium hair", and its corresponding brush hardness C conforms to the standard of "bristle" (this). Can abbreviate the ear diameter A, the ear length B, and the brush hardness C as "12-medium hair-bristle").

In order to further improve the accuracy of the actual pressure value of this embodiment, in step S3, the ear neck 50 is pressed against the pressure sensor member 23 until it is elastically curved to be displaced, and after that, it is performed a plurality of times. Obtain the average value of the acquired multiple pressure values. As an example, similarly, when the ear neck 50 has a diameter of 12 mm and the ear length B is "middle hair", the ear neck 50 is pressed against the pressure sensor member 23 until it is elastically curved based on the above-mentioned measurement operation. Displace and repeat, for example, five times. If each is measured as a pressure value of 116 g, 117 g, 115 g, 118 g, and 114 g, the actual pressure value of 116 g is obtained by averaging the pressure values (the error numerical range is within ± 5% of the comparative pressure value D of the control). (Pass), more objective and more accurate than the result of a single measurement, factors such as the thickness of the brush, the friction between the brushes, and the amount of water when the ear 50 gets wet. Avoid affecting the measurement results.

If the measurement result is acceptable, the ear 50 removed from the ear installation rod 40 becomes the brush as it is. If the measurement result is unacceptable, the ear 50 removed from the ear setting rod 40 adjusts the brush again, re-ties it, measures the adjusted ear 50 again, and continues until it passes.

The method for measuring brush classification and the standard matrix of the above-described embodiment The brushes classified and manufactured according to FIG. 100 display the ear diameter A, the ear length B, and the brush hardness C in numerical encoding. To explain by way of example, the encoding of "0413" is displayed on the rod 60 of the brush shown in FIG. As a general rule, the encoding is that the front two codes "04" have a spike diameter A and a diameter of 4 mm, and are called No. 4. If it is "05", the diameter of the ear diameter A is 5 mm and it is called No. 5, and it is inferred from this.
The third code represents the ear length B, where "1" is long hair, "2" is medium hair, and "3" is short hair.
The fourth code represents the brush hardness C, where "1" is bristles, "2" is standard hair, and "3" is soft hair. Therefore, when the encoding of "0413" is displayed on the rod body 60 of the brush, it means that the ear neck 50 connected to the rod body 60 of the brush is a standard of "No. 4-long hair-soft hair", that is, this. The display clearly identifies the brush standard.

From the above description, as a feature of the present invention, the corresponding actual pressure value is obtained based on each ear 50 based on the measurement method of the present invention and the application of the standard matrix diagram 100. Also, when classifying brushes, the actual pressure value given based on each head 50 derives the standard that belongs to it, and all the different heads 50 achieve the standardization of the brush with the standard that belongs to it, and the brush Make it easier to choose the right standard when choosing. As an example, I thought that it would be suitable when copying with the ear 50 of "12-medium hair-rigid hair", but it does not fit well in my hand, so "12-medium hair-standard hair" or "12-medium hair-soft hair" If you think that "12-medium hair-standard hair" will fit your hand best, and you want to buy it again at a later date, it will be the basis for purchasing "12-medium hair-standard hair". , It will be easier to choose and buy the brush that suits you best. In this way, standardization of brush classification can provide a basis for purchasing a brush.

In addition, the standard matrix diagram body using the measurement method for brush classification has a function of clearly classifying many types of brushes, which is useful for standardized classification of various different brushes. This brush classification standard matrix diagram is an epoch-making invention that achieves the function of standardizing and classifying a wide variety of different brushes, and is a basis for calligraphers to easily select the same type of brush. After that, when a calligrapher asks for a brush of the same quality again, even if six months or six years have passed, a brush of the same quality can be obtained based on the standard matrix diagram of this brush classification. The present invention can surely solve the problem that the inconsistency of the brush quality of the brush cannot be overcome for many years, and this is an invention with remarkable inventive step.

The comparative pressure value of the standard hair is a second constant multiple of the comparative pressure value of the soft hair, and the comparative pressure value of the bristles is classified into the hardness and belongs to an arbitrary ear length. Is the second constant multiple of the comparative pressure value of the standard hair, the first constant multiple is 1.16 times, the second constant multiple is 1.3 times, and the ear diameter is 4 mm in diameter. There are 18 types of ear diameters of 5, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm and 21 mm, and the head is the pressure. The process required to touch the sensor member and then press and displace it until it is elastically curved is that the tip is exposed by half the length of the tip and the tip is displaced. The pressure sensor member is pressed a plurality of times until it is elastically curved, the number of times is five, and the brush grip angle is tilted by 12 degrees with respect to the vertical direction of the pressure sensor member to reproduce the brush stroke. The measuring method for brush classification according to claim 1, wherein the downward pressing route for the pressure sensor member is inclined by 45 degrees with respect to the vertical direction of the pressure sensor member.
