Description

Technical Field

[0001] The present application relates to the technical field of material measurement, and in particular to a material measurement method, device, medium and equipment based on bulk weighing bills. Background Art

[0002] With the progress and development of society, people's demand for industrial products is also increasing, and the requirements for the weight accuracy of various ingredients of products are getting higher and higher. Especially for the measurement of bulk materials, it is usually necessary to measure and weigh the materials multiple times. If there is a certain error value in each measurement and weighing, the final measurement value or weighing value will deviate from the actual demand due to the accumulated error, thus causing the deviation of the product's ingredient weight.

[0003] At present, material measurement is done by weighing the scale pan and using the door to close in advance to end the material discharge. However, the random changes in the material discharge speed and drop cause weighing errors. Although existing batching equipment has adopted drop correction measures, this correction uses the difference between the actual weight of the current pan and the target weight to calculate the target weight of the next pan. This correction has obvious hysteresis and has no effect on the current pan. As for the drop of the next pan, there is an erroneous logic. Therefore, a method is needed to accurately measure each pan of material. Summary of the invention

[0020] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0021] Figure 1 FIG. 1 is a flow chart of a material measurement method based on a bulk scale bill provided by an exemplary embodiment of the present application. Figure 1As shown, the material measurement method based on the bulk scale order includes the following steps:

[0022] Step 110: Obtain the opening of the discharge port of the material bin.

[0023] The discharge port opening refers to the degree of opening of the discharge port of the material bin. Since the switch of the discharge port can be fully opened or partially opened, the opening of the discharge port can be adjusted to achieve different opening degrees, thereby adjusting the discharge amount per unit time of the material bin, that is, the discharge speed.

[0024] Step 120: Obtain the vibration frequency of the material bin.

[0025] The vibration frequency is the vibration frequency of the vibration motor installed on the material bin. Since the materials may be adhered to a certain extent during long-term storage in the material bin, including adhesion between materials and adhesion between materials and the wall of the material bin, the materials are not easy to slide or the discharge is not smooth when the discharge port of the material bin is opened. In order to ensure the normal discharge of the materials, the present application installs a vibration motor on the material bin, and uses the vibration motor to provide vibration force to vibrate the materials, so that the materials can slide out of the material bin smoothly. And the discharge speed of the materials can be adjusted by controlling the vibration frequency of the vibration motor.

[0026] Step 130: Calculate the discharge speed of the material bin according to the discharge port opening and the vibration frequency.

[0027] The calculation formula of the discharge speed is as follows: ;in, V is the discharging speed, is the discharge opening, t For the discharge time, f t is the vibration frequency of the current time, f 0 As the basic vibration frequency, g The present application calculates the discharge speed of the material bin according to the discharge port opening of the material bin and the vibration frequency of the vibration motor, wherein the larger the discharge port opening and the larger the vibration frequency at the current time, the faster the discharge speed.

[0028] Step 140: Calculate a first measurement value of the material according to the discharge speed.

[0029] After the discharge speed is calculated, the first measurement value of the material is calculated based on the discharge speed of the material. Specifically, the present application can calculate the amount of material discharged from the material bin based on the integral of the discharge speed over time.

[0030] Step 150: Obtain a second measurement value of the scale pan.

[0031] Among them, the weighing pan is set below the discharge port of the material bin. Usually, a weighing pan is set below the material bin to carry and weigh the materials. In the process of discharging materials, the second measurement value of the weighing pan is obtained in real time to obtain the amount of material on the weighing pan. However, due to the gravitational impact force of the material, the second measurement value obtained by weighing the weighing pan is greater than the actual weight of the material.

[0032] Step 160: Based on the discharge port opening, the discharge speed and the second measurement value, a third measurement value of the material is calculated.

[0033] The third measurement value is less than the second measurement value. The present application can estimate the impact force of the material on the weighing pan according to the discharge port opening and the discharge speed, and calculate the third measurement value of the material based on the impact force and the second measurement value obtained by weighing the weighing pan, that is, correct the measurement value of the weighing pan according to the discharge port opening and the discharge speed.

[0034] Step 170: According to the first measurement value and the third measurement value, a final measurement value of the material is obtained by comprehensive calculation.

[0035] After obtaining the first measurement value and the third measurement value through two measurement methods, the present application combines the first measurement value and the third measurement value to calculate the final measurement value of the material.

[0036] The present application provides a material measurement method based on a bulk weighing list, which obtains the opening of a material bin discharge port; wherein the discharge port opening indicates the degree of opening of the material bin discharge port; obtains the vibration frequency of the material bin; wherein the vibration frequency is the vibration frequency of a vibration motor arranged on the material bin; calculates the discharge speed of the material bin according to the discharge port opening and the vibration frequency; calculates the first measurement value of the material according to the discharge speed; obtains the second measurement value of the weighing pan; wherein the weighing pan is arranged below the discharge port of the material bin; calculates the third measurement value of the material based on the discharge port opening, the discharge speed and the second measurement value. The third measurement value is less than the second measurement value; the final measurement value of the material is obtained by comprehensive calculation based on the first measurement value and the third measurement value; that is, the discharge speed of the material bin is calculated according to the discharge port opening of the material bin and the vibration frequency of the vibration motor, and then the first measurement value of the material is calculated, and the third measurement value is calculated by combining the discharge port opening, the discharge speed and the measurement value of the weighing pan, and the final measurement value of the material is obtained by combining the first measurement value and the third measurement value. In the measurement process, multiple influencing factors are considered and the final measurement value is obtained by combining the measurement results from multiple angles to improve the measurement accuracy.

[0037] In one embodiment, the specific implementation of the above step 140 may be: calculating the first measurement value according to the discharge speed and the discharge time.

[0038] After calculating the material discharge speed, the present application combines the discharge time to calculate the cumulative discharge amount of the material bin, which is the material measurement value.

[0039] In one embodiment, the specific implementation of the above step 160 may be: the calculation formula of the third measurement value is as follows: ;in, m 3 is the third measurement value, m 2 is the second measurement value, is the discharge port opening, V 0 The basic discharging speed.

[0040] Specifically, after measuring and obtaining the second measurement value, the present application combines the discharge port opening and the discharge speed of the material bin to calculate the third measurement value through the above formula to obtain the material measurement value obtained by weighing the scale.

[0041] In one embodiment, the specific implementation method of the above step 170 can be: calculating the difference between the first measurement value and the third measurement value; calculating the ratio of the difference value and the first measurement value; if the ratio is less than a preset ratio threshold, taking the first measurement value or the third measurement value as the final measurement value of the material.

[0042] After obtaining the first measurement value and the third measurement value, the present application verifies the first measurement value and the third measurement value against each other by calculating the difference between the first measurement value and the third measurement value. If the ratio of the difference to the first measurement value is less than a preset ratio threshold, it means that the difference between the first measurement value and the third measurement value is small, that is, the first measurement value and the third measurement value are both relatively accurate. At this time, the final measurement value of any one of the first measurement value and the third measurement value can be selected as the seat material.

[0043] In one embodiment, the specific implementation of the above step 170 may be: if the ratio value is greater than or equal to the ratio threshold, then the discharge speed is reduced.

[0044] If the ratio of the difference value to the first measurement value is greater than or equal to the preset ratio threshold, it means that the difference between the first measurement value and the third measurement value is large, that is, at least one of the first measurement value and the third measurement value is inaccurate. At this time, the discharge speed can be reduced to improve the accuracy of the first measurement value, while reducing the impact force on the scale pan and improving the accuracy of the third measurement value.

[0045] In one embodiment, the material bin includes a plurality of discharge ports with different diameters; wherein, before step 110, the material metering method based on bulk weighing orders may further include: opening the plurality of discharge ports in sequence from small to large according to diameter.

[0046] Specifically, the material bin may include multiple discharge ports with different diameters. When opening the material bin, in order to improve the measuring accuracy of the first measuring value, the present application opens multiple discharge ports in sequence starting from the discharge port with a small diameter, thereby improving the discharge efficiency as much as possible while ensuring the measuring accuracy.

[0047] Preferably, the present application can also achieve precise control of the discharge volume by closing multiple discharge ports in sequence, and adjust the discharge efficiency by controlling the opening and closing time intervals of the multiple discharge ports.

[0048] In one embodiment, when multiple materials are discharged at the same time, since multiple materials enter the weighing pan at the same time, the second measurement value obtained by weighing the weighing pan is no longer the weight of a single material. Therefore, the present application can obtain the total amount of materials based on the first measurement values ​​of multiple materials, and verify the total amount of materials based on the weighing of the weighing pan to improve the weighing accuracy of the materials.

[0049] In one embodiment, the specific implementation of the above step 120 may be: calculating the vibration frequency according to the size of the material and the diameter of the discharge port of the material bin.

[0050] Since materials of different sizes are discharged from material bins with different discharge port diameters at different speeds, the present application can calculate the vibration frequency of the vibration motor based on the material size and the discharge port diameter of the material bin, combined with the expected discharge speed of the material, to ensure the discharge speed of the material.
