Description

Technical Field

[0001] The present invention relates to the technical field of cotton detection, and in particular to a touch method for testing the moisture regain rate of cotton samples. Background Art

[0002] In each inspection link of cotton notarization inspection laboratories, moisture regain rate detection of cotton samples is required in the three links of bagging and sample separation, pretreatment, and equilibration. According to the requirements of the "Regulations for Inspection in Cotton Quality Notarization Inspection Laboratories", the sampling ratio of moisture regain rate testing in each link is 10%. Currently, the original cotton moisture meter is used for testing in the public inspection laboratories. The testing principle is applicable to GB / T6102.2-2012 "Test Method for Moisture Regain of Raw Cotton - Resistance Method". During testing, pressure needs to be applied to the cotton to make it compact, and then the moisture regain rate of the compacted cotton is measured by the resistance method through a sensor. The testing speed is slow. Before applying pressure, it takes some time for manual pressure adjustment, which results in reduced testing efficiency and is laborious; moreover, the equipment is prone to damage due to long-term pressure application. These two problems seriously affect the accuracy and timeliness of moisture regain rate inspection data. In addition, the moisture regain rate testers used in domestic cotton public inspection laboratories are all in manual mode, which simply cannot meet the requirements of fast, efficient, and on-line detection of laboratory automated logistics.

[0003] The specific manifestations of the above problems are described in detail taking the Bole Laboratory of China Cotton Notarization Inspection as an example. The total cotton output in the Bole area is about 300,000 tons. The China Cotton Notarization Inspection Bole Laboratory needs to complete more than 7,100 batches of notarization inspections every year, with 186 samples in each batch. The standard weight of each cotton sample is 125 grams, which is packed into 19 sample boxes. The cotton samples packed into the sample boxes are already in a fluffy state without pressure restraint. The normal number of sampling tests for moisture regain rate is: 7,100 batches * 19 boxes / batch * 1 time / box * 3 times = 404,700 times. If the moisture regain rate test is unqualified and needs to be retested after repeated processing, the above number of tests will increase.

[0004] Currently, the XJ130k rapid moisture regain rate tester is used for testing in the Bole Inspection Laboratory. The weight of this moisture regain rate tester is 1.5 Kg, and the manually applied pressure is 49 N ± 5 N. The testing method requires the tester to hold the instrument handle to apply pressure. When the pressure indicator light is on, maintain the pressure for about 3 seconds before the test result is displayed. It is difficult to master the manual pressure application value, and the testing process requires continuous adjustment. The testing efficiency is low, the equipment is prone to damage due to long-term pressure application, the failure rate is high, and the reliability is low.

[0005] Judging from the situation of the Bole Laboratory, with the moisture regain rate testing frequency of up to more than 400,000 times per inspection season, plus the 1.5 Kg weight of the instrument and the 49 N ± 5 N applied pressure, it is not difficult to see that this is a time-consuming, laborious, and inefficient detection work. Summary of the Invention

[0006] The object of the present invention is to provide a touch method for testing the moisture regain rate of cotton samples. This touch method for testing the moisture regain rate of cotton samples can achieve automatic detection of the moisture regain rate of cotton samples. Moreover, by using an ultra-high frequency resonant sensor, only by gently touching the cotton sample with the sensor, the rapid testing of the moisture regain rate of the cotton sample can be realized, without manually operating the tester to apply pressure to the cotton, avoiding the adjustment of pressure, thus improving the testing efficiency, reducing the failure rate, and improving the reliability.

[0007] In order to achieve the above object, a touch method for testing the moisture regain rate of cotton samples provided by the present invention has the following specific implementation scheme:

[0008] A touch method for testing the moisture regain rate of cotton samples includes the following steps:

[0009] S10. Provide a tester, which includes a tray rack feeder, a main frame, an ultra-high frequency resonant sensor, a barcode reader, a driving mechanism, and a control mechanism; the driving mechanism is installed on the main frame; the ultra-high frequency resonant sensor and the barcode reader are installed on the driving mechanism; the control mechanism is electrically connected to the driving mechanism, the ultra-high frequency resonant sensor, and the barcode reader;

[0010] S20. Push the tray rack feeder into the detection area;

[0011] S30. Place the first cotton sample box in the tray rack feeder. The cotton sample box has N storage grids for placing cotton samples. Each storage grid corresponds to a position sequence test number from 1 to N, and an RFID tag is provided at the bottom of each storage grid;

[0012] S40. After the detection starts, the control mechanism first generates a random test number from 1 to N, and then controls the driving mechanism to drive the ultra-high frequency resonant sensor and the barcode reader to move to the position of the storage grid corresponding to the random test number, and move downward until it contacts the cotton sample;

[0013] S50. The barcode reader reads the RFID code at the bottom of the storage grid. At the same time, the ultra-high frequency resonant sensor detects the moisture content of the cotton. The control mechanism receives the barcode reading information and the moisture content information, and converts the obtained moisture content information into the moisture regain rate;

[0014] S60. Subsequently, stack the other cotton sample boxes one by one, and perform the operations of steps S30 - S50 one by one;

[0015] S70. When the required number of cotton sample boxes are stacked on the tray rack feeder, manually push away the tray rack feeder;

[0016] S80. Push the next pallet rack truck into the detection area, and repeat steps S20 to S70.

[0017] In one embodiment, the overall frame includes a bottom frame and a gantry installed on the bottom frame. The bottom frame forms a limiting cavity with one side open, and the driving mechanism is installed on the gantry; in step S20, the detection area is the limiting cavity.

[0018] In one embodiment, the bottom frame includes two relatively arranged first crossbars and a second crossbar connecting one ends of the two first crossbars, and the first crossbars and the second crossbar enclose the limiting cavity.

[0019] In one embodiment, the pallet rack truck has a braking structure. In step S20, after the pallet rack truck is moved into the detection area, the pallet rack truck is braked by the braking structure; in S70, the pallet rack truck is removed and the braking of the pallet rack truck by the braking structure is released.

[0020] In one embodiment, in step S60, each time a cotton sample box is inspected, the control mechanism controls the driving mechanism to drive the ultra-high frequency resonance sensor to first lift by the height of two cotton sample boxes on the basis of the height of the last inspected cotton sample box, and wait for the next cotton sample box to be placed.

[0021] In one embodiment, the code reader is a macro code reader, which is limited to reading the RFID code of the cotton sample in the uppermost cotton sample box and will not penetrate the uppermost cotton sample box to read the RFID code of the lower cotton sample box.

[0022] In one embodiment, in step S60, during the time of placing and taking the next cotton sample box onto the pallet rack truck, the moisture regain detection of the cotton sample in the previous cotton sample box is completed.

[0023] In one embodiment, in step S60, each time a cotton sample box is detected, the control mechanism controls the driving mechanism to drive the ultra-high frequency resonance sensor to start from the relative coordinate origin, rather than starting from the last actual detection position, to eliminate the continuous accumulation of moving distance errors.

[0024] In one embodiment, rollers are provided at the bottom of the overall frame; after step S80, there is also step S90. After the detection of the required number of cotton sample boxes is completed, the power of the tester is turned off, and the tester is pushed to the vacant position between the sample dividing tables.

[0025] Based on the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0026] The present invention provides a tester including a control mechanism, a driving mechanism, and an ultra-high frequency resonance sensor. During testing, the control mechanism can control the driving mechanism to drive the ultra-high frequency resonance sensor to move to the position where the cotton sample to be measured is located. As long as the cotton sample is gently touched, the ultra-high frequency resonance sensor is used to detect the moisture content of the cotton, and then the control mechanism converts the moisture content of the cotton into the moisture regain rate. Thus, the moisture regain rate of the cotton sample in the cotton sample box to be measured can be obtained. The whole process is automated, eliminating the need to manually adjust the pressure on the cotton, saving time and effort, improving the testing efficiency and accuracy. Moreover, since there is no need for manual pressure application, damage to the tester caused by pressure application is also avoided, extending the service life of the tester. And each detection is carried out at a random position from 1 to N issued by the control system, well meeting the requirement of random sampling in the cotton inspection regulations. It eliminates the interference of human factors and further improves the accuracy and reliability of cotton detection data. Brief Description of the Drawings

Detailed Embodiment

[0032] To facilitate the understanding of the present invention, the specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings of the specification.

[0033] Unless otherwise specified or defined, the "first, second, ..." used herein are only for differentiating names and do not represent specific quantities or orders.

[0034] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] It should be noted that "fixed to" and "connected to" in this article can be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0036] The present invention discloses a touch method for testing the moisture regain rate of cotton samples, and the method includes the following steps:

[0037] S10. Provide a tester, Figure 1 and Figure 2 As shown, the tester includes a tray rack trolley 70, a main frame 10, an ultra-high frequency resonance sensor 30, a code reader 40, a driving mechanism 20, and a control mechanism 50; the driving mechanism 20 is installed on the main frame 10; the ultra-high frequency resonance sensor 30 and the code reader 40 are installed on the driving mechanism 20; the control mechanism 50 is electrically connected to the driving mechanism 20, the ultra-high frequency resonance sensor 30, and the code reader 40.

[0038] Among them, the code reader 40 is used to read the RFID tag at the bottom of the cotton sample box. The code reader 40 is a macro code reader, which is limited to reading the RFID code of the cotton sample in the uppermost cotton sample box and will not penetrate the uppermost cotton sample box to read the RFID code in the lower sample box; the ultra-high frequency resonance sensor 30 is used to detect the moisture content of the cotton sample. Preferably, an ultra-high frequency resonance sensor 30 with a detection response time in the millisecond level is selected; the driving mechanism 20 is installed on the gantry 12 and is connected to the ultra-high frequency resonance sensor 30 and the code reader 40 for driving the ultra-high frequency resonance sensor 30 and the code reader 40 to approach the cotton sample box; the control mechanism 50 is electrically connected to the driving mechanism 20, the ultra-high frequency resonance sensor 30, and the code reader 40, and is used to control the operation of the driving mechanism 20 and receive the information detected by the ultra-high frequency resonance sensor 30 and the code reader 40, and calculate the moisture regain rate of the cotton sample placed in the cotton sample box according to the moisture content information sent by the received ultra-high frequency resonance sensor 30.

[0039] This tester can implement a touch method for cotton samples. The touch method originates from a technology that uses the ultra-high frequency resonance principle to measure the moisture content of items. Measuring instruments using this technology have had mature and extensive use experiences in fields such as metallurgy and mining, but it is the first innovative attempt in the field of cotton detection.

[0040] Further, the overall frame 10 includes a bottom frame 11 and a gantry 12 mounted on the bottom frame 11. The gantry 12 includes two columns 121 and a cross beam 122. One ends of the two columns 121 are respectively fixed on the bottom frame 11, and the other ends are connected to the cross beam 122; the driving mechanism 20 is installed between the two columns 121.

[0041] The driving mechanism 20 includes a Z-axis driving component 21 installed on the column 121, an X-axis driving component 22 connected to the Z-axis driving component 21, and a Y-axis driving component 23 connected to the X-axis driving component 22; the ultra-high frequency resonance sensor 30 and the code reader 40 are both installed on the Y-axis driving component 23. The Z-axis driving component 21 is used to drive the ultra-high frequency resonance sensor 30 and the code reader 40 to move along the Z-axis direction, and the X-axis driving component 22 and the Y-axis driving component 23 are used to drive the ultra-high frequency resonance sensor 30 and the code reader 40 to move along the X-axis direction and the Y-axis direction. The Z-axis driving component 21, the X-axis driving component 22, and the Y-axis driving component 23 can be a driving mechanism composed of a motor + a lead screw, or a mechanism composed of a cylinder + a slider, or a mechanism composed of a servo motor + a synchronous belt, etc., and will not be specifically introduced here.

[0042] As Figure 2 shown, the pallet rack truck 70 includes a tray 71 for holding cotton sample boxes and truck rollers 72 provided below the tray 71.

[0043] Further, guide limiting plates 73 protruding from the top of the tray 71 are provided on four sides of the tray 71, which are used to limit the cotton sample boxes to fixed positions on the tray 71. While ensuring that the positions of the stacked cotton sample boxes on the tray 71 are relatively fixed, it can also prevent the stacked cotton sample boxes from sliding out of the tray 71.

[0044] The tester further includes frame rollers 80, and the frame rollers 80 are provided at the bottom of the bottom frame 11 of the overall frame 10, which is used to facilitate the movement of the entire tester.

[0045] S20: Push the pallet rack truck 70 into the detection area.

[0046] Specifically, in one embodiment, the bottom frame 11 forms a limiting cavity 113 with one side open; in step S20, the detection area is the limiting cavity 113. Further, as Figure 3As shown in the figure, the bottom frame 11 includes two relatively arranged first crossbars 111 and a second crossbar 112 connecting one end of the two first crossbars 111. The first crossbar 111 and the second crossbar 112 enclose a limiting cavity 113 of the detection area. Further, a track frame 114 for further positioning the pallet rack truck 70 is arranged in the limiting cavity 113. The track frame 114 includes two parallel tracks 1141, two guide plates 1144 located at the open end of the limiting cavity 113, and a connecting plate 1145 connecting the two tracks 1141 at the rear end of the limiting cavity 113; the two tracks 1141 are respectively installed on the two first crossbars 111; the two guide plates 1144 are respectively arranged at one end of the two tracks 1141 far from the first crossbar 111 and are arranged in a V shape, facilitating the entry and positioning of the pallet rack truck 70. Specifically, the cross-section of the track 1141 is L-shaped. The track 1141 includes a first plate 1142 connecting the first crossbar 111 and a second plate 1143 vertically connecting the first plate 1142. The second plate 1143 is arranged adjacent to the bottom surface of the first crossbar 111. A guiding channel is formed between the first plate 1142 and the second plate 1143. When the pallet rack truck 70 enters the limiting cavity 113, the vehicle rollers 72 on both sides of the pallet rack truck 70 respectively enter the guiding channels on the two tracks 1141 of the track frame 114. Under the guiding action of the guiding channel, the pallet rack truck 70 can perform stable linear motion and is not prone to shaking, ensuring the stability of the cotton sample box placed on the pallet rack truck 70. After the pallet rack truck 70 enters the track frame 114 in the limiting cavity 113 of the bottom frame 11, the track frame 114 can position the pallet rack truck 70, making the position of the cotton sample box in the limiting cavity 113 determined, facilitating the subsequent tester to accurately measure each cotton sample box placed on the pallet rack truck 70 one by one. Moreover, the setting of the bottom frame 11 with the attached track frame 114 is not only simple in structure but also convenient for the pallet rack truck 70 to enter and exit the limiting cavity 113.

[0047] In an embodiment, the pallet rack truck 70 has a braking structure. In step S20, after the pallet rack truck 70 is pushed into the detection area, the pallet rack truck 70 is braked through the braking structure so that the pallet rack truck 70 will not move after moving to the detection area, ensuring the detection accuracy. Further, the braking structure is a manual braking handle 74 arranged on the pallet 71. By manually pulling out the manual braking handle 74, the pallet rack truck 70 is braked.

[0048] S30. Place the first cotton sample box in the pallet rack truck 70. Each cotton sample box has N storage grids for placing cotton samples. Each storage grid corresponds to a test number with a natural sequence code from 1 to N, and an RFID tag is arranged below each storage grid, with a total of N.

[0049] The specific value of N is selected according to the size of the cotton sample box. Specifically, taking N as 10 for illustration, before the test, the control mechanism 50 issues any random test number within the range of 1 - 10. The ultra-high frequency resonance sensor 30 is quickly moved to the storage grid position corresponding to the test number under the traction of the driving mechanism 20. The driving mechanism 20 drives the ultra-high frequency resonance sensor 30 to gently touch the cotton sample, and at the same time drives the code reader 40 close to the storage grid, and the moisture regain test of the cotton sample and the information reading of the rfid tag at the bottom of the cotton sample box can be completed instantly. When detecting the moisture regain of cotton in other cotton sample boxes subsequently, since the test numbers issued by the control mechanism 50 before each test are random, random sampling detection of cotton samples in each cotton sample box can be completed, strictly implementing the cotton inspection regulations, completely avoiding human intervention, and improving the true reliability of the test data.

[0050] S40. After the detection starts, the control mechanism 50 first randomly generates a test number within the range of 1 - N, and then controls the driving mechanism 20 to drive the ultra-high frequency resonance sensor 30 and the code reader 40 to move to the storage grid position corresponding to the test number until they contact the cotton sample in the storage grid.

[0051] S50. The code reader 40 reads the rfid code at the bottom of the storage grid, and the ultra-high frequency resonance sensor 30 detects the moisture content of the cotton sample. The control mechanism 50 receives the rfid code information and the moisture content information, and converts the obtained moisture content information into moisture regain.

[0052] Specifically, the code reader 40 reads the rfid code at the bottom of the storage grid corresponding to the random test number, and sends the obtained information to the control mechanism 50 for storage. At the same time, the control mechanism 50 issues a detection instruction. The ultra-high frequency resonance sensor 30 tests the moisture content value of the cotton sample and sends it to the control mechanism 50, which is simultaneously converted into a moisture regain value and stored. The internal measurement and control program of the control mechanism 50 will associate the test number, rfid code, and moisture regain value of the above sample box. When detecting the moisture regain of cotton samples in each cotton sample box, the association of the test number, rfid code, and 32-bit identity bar code information of the cotton is completed first.

[0053] Among them, regarding the calculation of moisture regain from moisture content, refer to the national standard document GBT9995 - 1997 Determination of moisture content and moisture regain of textile materials - oven drying method standard, which specifically describes the counting method of converting moisture content into moisture regain.

[0054] The test principle of the ultra-high frequency resonant sensor is as follows: a relatively constant ultra-high frequency resonant detection field is formed between the ultra-high frequency resonant sensor 30 and the cotton sample to be measured; the control mechanism 50 detects and analyzes the cotton sample to be measured with a preset ultra-high frequency resonance coefficient; when trace moisture appears in the cotton sample to be measured, the entire constant ultra-high frequency resonant detection field will be slightly disturbed; the control mechanism 50 will instantaneously digitize and analyze this slight moisture disturbance signal into the moisture content, and then convert the moisture content into the regain rate.

[0055] In one embodiment, the tester further includes an operation display screen 60 electrically connected to the control mechanism 50. In step S50, the control mechanism 50 sends the information obtained during the detection to the operation display screen 60.

[0056] Specifically, the operation display screen 60 is used to send operation instructions to the control mechanism 50 and display the detection results, and receive the detection result information sent by the control mechanism 50, which facilitates the staff to operate the entire tester and read the detection results. The operation display screen 60 is provided with touch operation buttons. By operating the touch operation buttons, the operation display screen 60 sends operation instructions to the control mechanism 50; after receiving the information obtained by the ultra-high frequency resonant sensor 30 and the barcode reader 40, the control mechanism 50 will send all the processed information to the operation display screen 60 for display.

[0057] In one embodiment, in step S50, the control mechanism 50 can also wirelessly transmit the detection information to the background server.

[0058] S60. After completing the regain rate detection of the first cotton sample box, subsequent cotton sample boxes are stacked one by one, and the operations of steps S20 - S50 are performed one by one.

[0059] In one embodiment, in step S60, each time after sampling and inspecting a cotton sample box, the control mechanism 50 controls the driving mechanism 20 to drive the ultra-high frequency resonant sensor 30 to first lift by the height of two cotton sample boxes based on the height of the last detected cotton sample box, and wait for the next cotton sample box to be placed. This can not only shorten the vertical moving distance of the ultra-high frequency resonant sensor 30, shorten the test time, but also prevent the staff from bumping into the ultra-high frequency resonant sensor 30 when placing the cotton sample box.

[0060] Each time the ultra-high frequency resonant sensor 30 starts from the relative coordinate origin instead of the position where the previous test was completed, effectively preventing the transmission and accumulation of position errors.

[0061] Only one stack of cotton sample boxes is palletized on each pallet rack truck 70. When palletizing the cotton sample boxes on the pallet rack truck 70, each time a cotton sample box is palletized, the operator manually clicks the start detection button on the operation display screen 60, and the control mechanism 50 controls the drive mechanism 20 to drive the UHF resonant sensor 30 and the barcode reader 40 to act. Moreover, each time the operator presses the detection start button, the control mechanism 50 automatically counts once and transmits it to the operation display screen 60 for display.

[0062] Further, in step S60, within the time of placing the next cotton sample box onto the pallet rack truck, the moisture regain rate of the cotton sample in the previous cotton sample box is detected. In this way, the tester can quickly complete the detection of the moisture regain rate of the cotton sample without adding extra test time, which can greatly improve the detection work efficiency.

[0063] S70: When the required number of cotton sample boxes are palletized on the pallet rack truck 70, push away the pallet rack truck 70.

[0064] In step S70, when the pallet rack truck 70 is equipped with a braking mechanism, when removing the pallet rack truck 70, the operator needs to release the braking structure of the pallet rack truck 70 by the manual brake handle 74 before the pallet rack truck 70 can be pushed away.

[0065] S80: Push the next pallet rack truck 70 into the detection area and repeat steps S30 to S70.

[0066] S90: After completing the detection of the required number of cotton sample boxes, turn off the power of the tester and push the tester to the empty space between the sample dividing tables.

[0067] Specifically, after completing the detection of the cotton samples in the required number of cotton sample boxes, pushing the tester with the power turned off to the empty space between the sample dividing tables can reduce the occupation of laboratory space and ensure the beauty of the laboratory.

[0068] In summary, the present invention provides a tester including a control mechanism 50, a driving mechanism 20, a ultra-high frequency resonance sensor 30, and a code reader 40. During testing, the control mechanism 50 can control the driving mechanism 20 to drive the ultra-high frequency resonance sensor 30 to move to the position where the cotton sample to be measured is located. As long as the cotton sample is gently touched to form an ultra-high frequency resonance area in the detection area, the moisture content of the cotton can be instantly detected. Then, the control mechanism 50 converts the moisture content of the cotton into the regain rate, and the regain rate of the cotton sample in the cotton sample box to be measured can be obtained. The regain rate value can not only be stored locally, but also be uploaded to the background server at any time. The whole process is automated, eliminating the need to manually adjust the pressure on the cotton, saving time and effort, improving the testing efficiency and accuracy. Moreover, since there is no need for manual pressure application, the damage to the tester caused by pressure application is also avoided, improving the service life of the tester. And each detection is carried out at a random position from 1 to N issued by the control system, well meeting the requirement of random sampling in the cotton inspection regulations, eliminating the interference of human factors, and further improving the accuracy and reliability of the cotton detection data.
