Determination method of brush classification

Abstract

The present invention provides a method for measuring the classification of writing brushes and a specification matrix table used in the method. The pen head is connected to a pen holder at its root, and the pen holder is fixed on a detection machine to simulate the pen holding angle, and the pen head faces a pressure sensing component set up on the detection machine. The detection machine drives the pen holder to simulate the route of pen pressing down, so that the pen head is displaced and presses on the pressure sensing component until it is elastically bent. This is repeated several times, and the average value of the multiple pressure values ​​obtained is taken to measure the actual pressure value. When a comparison pressure value is met by comparing with the specification matrix table, the pen head has a pen diameter, a tip length and a corresponding brush hair hardness belonging to the comparison pressure value that meets the requirements, thereby forming the present invention.

Technical Field

Background Art

[0002] The brushes produced on the market are all handmade by brush makers. The craftsmanship is purely based on the personal experience of the brush makers. There are currently no standardized specifications. Therefore, even if the same brush is made by the same brush maker, there will still be differences in the quality of the brush. If the same brush is made by brush makers with different experience, the difference in quality will be more obvious.

[0003] As mentioned above, due to the obvious differences in the properties of the current brush manufacturing method, when people buy brushes, especially calligraphers and Chinese painters, even if they find a suitable brush from hundreds of brushes, when they buy the same brush next time, even if it is marked as the same brush, there is still the problem of different properties, which leads to the trouble of having to choose a new brush because it is not convenient to write, and there is no basis for selection. Therefore, how to solve the problem faced by the current brushes without standardized specifications is the main focus of the present invention. Summary of the invention

[0049] In order to facilitate the description of the central idea of ​​the present invention in the above invention content column, a specific embodiment is used for expression. Various objects in the embodiment are depicted according to the proportion, size, deformation or displacement suitable for description, rather than being drawn according to the proportion of the actual element, which is described first.

[0050] The present invention provides a method for determining the classification of brushes and a specification matrix table used in the method. First of all, it should be noted that the brushes to be classified in the following embodiments are as follows: Figure 1 , Figure 2 As shown, the diameter of the root of the brush head 50 of the writing brush (hereinafter referred to as the brush diameter) is 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, and 21mm, and eighteen different brush diameters A are distinguished, and each brush diameter A is further distinguished into a plurality of tip lengths B (the tip length B referred to in the present invention refers to the length of the brush tip after deducting the root of the brush head 50). For example, each brush diameter A in the present embodiment has three tip lengths B (in mm), namely, long tip length, medium tip length, and short tip length, and in Figure 1 The root length of the brush head of each pen diameter A is shown in the figure; furthermore, each tip length B is further distinguished into a plurality of brush hair hardness C, such as the present embodiment can distinguish three types of brush hair hardness C, namely hard brush hair, standard brush hair, and soft brush hair. Therefore, in the embodiment described below, the brushes to be classified have eighteen pen diameters A, each pen diameter A has three types of tip lengths B, and each tip length B has three types of brush hair hardness C, so the present embodiment can classify 162 different specifications of brushes, but the specifications and quantity of the brush classification described here are only for auxiliary explanation of the present embodiment, and are not limited to the above 162 specifications.

[0051] In this embodiment, the measuring method pre-establishes a brush classification specification matrix table 100 (eg, Figure 2 As shown in FIG. 1 , eighteen kinds of pen diameters A are distinguished according to the diameter size (4 mm to 21 mm) of the root of the brush head 50 of the brush to be classified. The pen diameter A is as follows: Figure 2 As shown in the header in the column of; each pen diameter A is distinguished into the tip length B as mentioned above, such as the long tip length, medium tip length, and short tip length, and each tip length B is further distinguished into the brush hair hardness C as mentioned above, such as the hard brush hair, standard brush hair, and soft brush hair. The tip length B and the corresponding brush hair hardness C are shown as Figure 2 As shown in the headers of the horizontal columns, a specification matrix table 100 of one hundred and sixty-two specifications of this embodiment is formed.

[0052] exist Figure 2 In the specification matrix table 100 shown, each brush diameter A corresponds to each brush hair hardness C in each tip length B and has a corresponding comparison pressure value D. When classifying brushes, the brush head of each brush is based on the brush diameter A and tip length B, and the comparison pressure value D corresponding to the brush hair hardness C listed in the specification matrix table 100 is used as a comparison standard to classify the brushes.

[0053] Furthermore, in Figure 2 In the specification matrix table 100 shown, the three types of tip lengths B, namely long tip length, medium tip length and short tip length, are distinguished by each pen diameter A. The comparative pressure value D of the hardness C of any brush hair within the tip length B of the medium tip length is 1.16 times (defined as the first constant multiple) of the comparative pressure value D of the hardness C of any brush hair within the tip length B of the long tip length in the same pen diameter A; the comparative pressure value D of the hardness C of any brush hair within the tip length B of the short tip length is 1.16 times the comparative pressure value D of the hardness C of any brush hair within the tip length B of the medium tip length in the same pen diameter A. For example, for a pen tip with the same diameter A of 5mm, the comparative pressure value D (25g) corresponding to the tip length B of the middle tip and the hardness C of the standard bristles is 1.16 times (rounded to the integer) the comparative pressure value D (22g) corresponding to the tip length B of the long tip and the same hardness C of the bristles; for a pen tip with the same diameter A of 5mm, the comparative pressure value D (29g) corresponding to the tip length B of the short tip and the hardness C of the standard bristles is 1.16 times the comparative pressure value D (25g) corresponding to the tip length B of the middle tip and the same hardness C of the bristles, and the calculation for different pen diameters A is similar.

[0054] As above, also in Figure 2In the specification matrix table 100 shown, each tip length B distinguishes three types of brush hair hardness C, namely hard brush hair, standard brush hair, and soft brush hair. Among the brush hair hardness C belonging to any tip length B, the comparison pressure value D of the standard brush hair is 1.3 times the comparison pressure value D of the soft brush hair (defined as the second constant multiple here), and the comparison pressure value D of the hard brush hair is 1.3 times the comparison pressure value D of the standard brush hair. For example, for a pen tip with the same diameter A of 5mm and tip length B of the middle tip, the hardness C of the brush hair is the comparative pressure value D (25g) of the standard brush hair, which is 1.3 times (rounded to the integer value) the comparative pressure value D (19g) of the hardness C of the soft brush hair; for a pen tip with the same diameter A of 5mm and tip length B of the middle tip, the hardness C of the brush hair is the comparative pressure value D (33g) of the hard brush hair, which is 1.3 times the comparative pressure value D (25g) of the hardness C of the standard brush hair, and the calculations for different pen diameters A and tip lengths B are similar. The above-mentioned first constant multiple and second constant multiple, i.e., 1.16 times of the tip length B and 1.3 times of the hardness C of the brush hair, are the better results obtained after many years of repeated verification, but the present invention is not limited thereto, for example, the first constant multiple or the second constant multiple can be adjusted within the range of 1.1-1.5 times.

[0055] As described above, the comparison pressure value D of each pen diameter A at different tip lengths B and corresponding pen hair hardness C can be obtained by the first constant multiple and the second constant multiple mentioned above. Figure 2 When the specification matrix table 100 is prepared, among the eighteen pen diameters (4mm~21mm), the present invention can empirically measure the comparison pressure value D of the tip length B as the center tip length and the brush hair hardness C as the standard brush hair in the pen diameters A of 5mm, 11mm and 17mm respectively, and then establish the comparison pressure value D of all pen diameters A of 4mm~21mm by averaging, and the comparison pressure value D corresponding to the pen diameter A decreases from high to low from large to small, and calculates the comparison pressure value D of the brush hair hardness C corresponding to all tip lengths B in the above manner according to the first constant multiple and the second constant multiple.

[0056] like Figures 5 and 6 As shown, the device used in the method for determining the classification of writing brushes in this embodiment includes a calibration platform 10, a detection machine 20, and an electronic control unit 30. Figure 5 As shown, the calibration platform 10 is provided with a calibration head 11, one end of which is pointed. In this embodiment, the calibration head 11 is arranged above the calibration platform 10 with the pointed end facing downward. Figure 6As shown, the inspection machine 20 in this embodiment includes a base 21, a clamping device 22 and a pressure sensing member 23. The clamping device 22 includes a moving member 221 and a positioning seat 222. The moving member 221 is arranged on the base 21 and connected to a driving member 24. The positioning seat 222 is arranged on the moving member 221. The pressure sensing member 23 and the driving member 24 are both electrically connected to the electronic control unit 30. The electronic control unit 30 controls the driving member 24 to drive the moving member 221 to move. The specification matrix table 100 is electronically stored in the electronic control unit 30. The electronic control unit 30 has a display screen 31. The specification matrix table 100 can also be electronically stored in a terminal device (not shown in the figure), such as stored in a computer or a smart phone for display, so as to serve as a basis for classifying brushes; or, the specification matrix table 100 can also be physical, such as marked on paper or board. The pressure sensing element 23 in this embodiment is a load cell, and the actual pressure value in this embodiment is the load measured by the pressure sensing element 23 and is expressed in g (grams) as the same unit as the comparison pressure value D.

[0057] In this embodiment, the base 21 defines an X-axis direction and a Y-axis direction that are horizontally orthogonal, and defines a Z-axis direction that is vertically orthogonal to the X-axis direction and the Y-axis direction. The moving member 221 of this embodiment is driven by the driving member 24 to move relative to the base 21 along at least one of the X-axis direction, the Y-axis direction and the Z-axis direction. The driving member 24 of this embodiment is a servo motor and is connected to the moving member 221 by a lead screw (not shown in the figure), and the positioning seat 222 is disposed on the moving member 221 via a slide seat and a slide rail (not shown in the figure). The pressure sensing member 23 is disposed in the Z-axis direction.

[0058] The determination method of the brush classification is as follows in the steps of this embodiment: Figure 3 The detailed description is as follows:

[0059] First, a pen tip 50 to be tested is connected to a pen holder 40 at its root (step S1). The pen holder 40 is made of aluminum in this embodiment and includes a rod body 41 and a head 42. The head 42 is connected to one end of the rod body 41. Then, the pen tip 50 is connected to the head 42 at its root (step S2). Figure 4 The pen holder 40 used in this embodiment is made of aluminum mainly to ensure that the pen holder 40 will not have dimensional errors due to environmental changes, and to avoid dimensional changes caused by temperature or humidity differences due to the use of different woods to form the pen holder. In addition, the combination of the rod body 41 and the head 42 in this embodiment only has one rod body 41, and corresponding heads 42 corresponding to the eighteen pen diameters A of this embodiment are available for selection and use. Here, only one head 42 is taken as an example.

[0060] After the step of connecting the pen tip 50 to the pen holder 40 at the root is completed, the pen holder 40 can be fixed on the detection machine 20 to simulate the pen holding angle. Since the actual pen holding action is simulated, the pen tip 50 can be wetted first, which has the advantage of being closer to the actual pen movement. In this embodiment, before the pen holder 40 is fixed on the detection machine 20 to simulate the pen holding angle, the pen tip 50 is wetted and combed to make the pen tip 50 sharp, and then the pen holder 40 is positioned on the calibration table 10 (such as Figure 5 As shown in the figure, the pen tip 50 is made upright with the pen holder 40, and the fixed pen tip 50 faces the pointed end of the calibration head 11 with the pointed end thereof, and when the two tips are aligned, the pointed end of the pen tip 50 is confirmed to be the alignment center. The action of confirming that the pointed end of the pen tip 50 is the alignment center has the main advantage of ensuring that when the pen tip 50 is fixed to the inspection machine 20 with the pen holder 40, there will be no measurement error caused by the eccentricity of the pointed end of the pen tip 50.

[0061] After the pointed end of the pen tip 50 is confirmed to be aligned with the center, the pen holder 40 can be fixed on the inspection machine 20 (such as Figure 6 ), and the pen holder 40 is fixed to simulate the pen holding angle, and the pen head 50 is facing the pressure sensing element 23 provided on the detection machine 20 (step S2), that is, the pen head 50 is facing upward toward the Z axis. In this embodiment, the pen holder 40 is fixed to the positioning seat 222, and when fixed, it is tilted 12 degrees relative to the vertical direction of the pressure sensing element 23 as the simulated pen holding angle according to the human writing habit.

[0062] When the pen holder 40 is fixed on the detection machine 20 at the simulated pen holding angle, it is also necessary to set the route, displacement speed and stroke of the detection machine 20 to drive the pen holder 40 to move. In the route, the pen holder 40 is fixed at the positioning seat 222 at a simulated pen holding angle, and is tilted 12 degrees relative to the vertical direction of the pressure sensing component 23, and then the detection machine 20 drives the pen holder 40 to move along the route of simulating pen pressure. In this embodiment, the pen holder 40 is driven to move along a route that is tilted 45 degrees relative to the vertical direction of the pressure sensing component 23. The displacement speed, that is, the speed at which the electronic control unit 30 controls the driving component 24 to drive the moving component 221 to move, is set to 50 cm / min in this embodiment. This displacement speed simulates the speed of a person writing with a brush.

[0063] The stroke refers to the stroke required for the pen tip 50 to move from touching the pressure sensing element 23 to the elastic bending state, and in this embodiment is set to half of the length of the pen tip 50 exposed from the pen holder 40; for example, the pen tip 50 with a pen diameter A of 10 mm has a short tip length B of 38.5 mm (e.g. Figure 1As shown), that is, the length of the pen tip 50 that will be exposed in the pen body 40 after deducting the length of 7mm at the root, half of its length is approximately 19mm (rounded to an integer), so the required stroke of the pen tip 50 from touching the pressure sensing component 23 to displacing to the elastic bending shape can be set to 19mm, and the required strokes for other pen diameters A corresponding to each tip length B are similar.

[0064] For example, if the pen tip 50 has a diameter of 12 mm and the tip length B is the middle tip length, the stroke required for displacement during measurement is half the tip length B (53 mm), which is about 27 mm (rounded to an integer). When the pen holder 40 has been fixed to the positioning seat 222 by simulating the pen holding angle, and the displacement route, stroke and displacement speed of the pen holder 40 have been set, the pen tip 50 can be adjusted through the clamping device 22 until the tip of the pen slightly touches the pressure sensor 23 (such as Fig. 7A As shown in the figure, the electronic control unit 30 is started to control the driving member 24 to drive the moving member 221 to move (along the two axes of the X-axis and the Z-axis and at an inclined angle of 45 degrees), that is, the speed is consistent and stable. At this time, the pen head 50 moves along the simulated pen holding angle and the simulated pen pressing route (as shown in the figure). Figure 7B As shown), the pressure sensing element 23 is displaced 27mm from the touch to the elastic bending state (step S3). At this time, the actual pressure value measured is 116g. This actual pressure value will be displayed on the display screen 31, and then the electronic control unit 30 compares the measured actual pressure value with the comparison pressure value D in the aforementioned specification matrix table 100 to see if it is consistent (step S4). After comparison, it is found that the pen tip 50 has a diameter of 12mm and the tip length B is the middle tip length. The actual pressure value 116g is consistent with the comparison pressure value D (also 116g) of the hardness C of the pen hair according to the specification matrix table 100. The pen tip 50 is in accordance with the comparison pressure value D of 116g, which belongs to the specification of pen diameter A of 12mm, tip length B of the middle tip length, and the corresponding hardness C of the pen hair (the specification can be referred to as: 12-medium-hard according to the pen diameter A, tip length B and pen hair hardness C).

[0065] In order to further increase the accuracy of the actual pressure value of this embodiment, after the pen tip 50 is displaced and the pressure sensing element 23 is pressed to an elastic bending state for several times in step S3, the multiple pressure values ​​obtained are averaged. For example, if the pen tip 50 has a diameter of 12 mm and the tip length B is the middle tip length, the pen tip 50 is displaced and the pressure sensing element 23 is pressed to an elastic bending state according to the above-mentioned measurement action, and the measurement is repeated for five times, assuming that the pressure values ​​of 116g, 117g, 115g, 118g, and 114g are measured respectively, and after averaging, the actual pressure value of 116g can still be obtained (the error value range is within ±5% of the control pressure value D for acceptance), and the result of the measurement performed only once will be relatively objective and more accurate, so as to avoid the influence of the measurement result due to factors such as the thickness of the brush hair, the friction between the brush hairs, and the amount of water when the pen tip 50 is wetted.

[0066] When the test result is qualified, the pen head 50 removed from the pen holder 40 can be made into a writing brush. When the test result is unqualified, the pen head 50 removed from the pen holder 40 can be re-adjusted and re-tied, and the adjusted pen head 50 can be tested again until the test result is qualified.

[0067] The brushes manufactured by the brush classification determination method and the specification matrix table 100 of the above-mentioned embodiment have the brush diameter A, the tip length B and the brush hair hardness C digitally coded and marked. Figure 8 The shaft 60 of the brush shown is marked with a code of 0413. The coding principle is that the first two codes 04 represent the pen diameter A, which is 4mm in diameter and is called No. 4, and if it is 05, it represents the pen diameter A is 5mm in diameter and is called No. 5, and so on; the third code represents the tip length B, 1 is long, 2 is medium, and 3 is short; the fourth code represents the hardness of the brush hair C, 1 is hard, 2 is standard, and 3 is soft. Therefore, the shaft 60 of the brush is marked with a code of 0413, indicating that the brush head 50 connected to the shaft 60 of the brush is of the specification of No. 4-long-soft, and the specification of the brush can be clearly identified by this marking.

[0068] From the above description, it is not difficult to find that the characteristic of the present invention is that, through the measuring method of the present invention and in conjunction with the application of the specification matrix table 100, the corresponding actual pressure value of each brush head 50 can be measured, and when the writing brushes are classified, the exclusive specifications of each brush head 50 are determined according to the actual pressure value measured, so that different brush heads 50 have their own exclusive specifications to achieve the standardization of the specifications of the writing brushes, which can make it easy for people to compare the applicable specifications when selecting writing brushes. For example, if it is considered that the 12-medium-hard pen head 50 is suitable for writing but still a little uncomfortable, you can try 12-medium-standard or 12-medium-soft instead. If you finally think that 12-medium-standard is the most convenient, you can use 12-medium-standard as the basis for repeated purchases of writing brushes in the future, so as to facilitate the purchase of the writing brush that you think is most suitable. The specification standardization of the writing brush classification can achieve the effect of providing a basis for purchasing writing brushes.

[0069] In addition, the specification matrix table used in the brush classification and measurement method itself has the function of clearly classifying a variety of brushes, which is conducive to the standardized classification of a variety of different brushes. This brush classification specification matrix table provides a groundbreaking invention, which achieves the function of standardized classification of a variety of different brushes, and allows calligraphers to simply choose brushes with the same brush nature. With this reference, when calligraphers want to obtain brushes with the same brush nature again, no matter if the interval is six months or six years, they can still obtain brushes with the same brush nature according to this brush classification specification matrix table. The present invention has indeed solved the long-standing problem of not being able to overcome the inconsistency of brush nature.

[0070] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
