Description

Technical Field

[0002] Sampling is an essential part of inspection and testing, covering multiple links such as sample extraction, preparation, storage, and transportation, and is an important basis for ensuring the fairness and accuracy of inspection and testing results. Standards such as "Technical Specifications for Vegetable Sampling NY / T2103-2011", "Sampling Specifications for Veterinary Drug Residue Monitoring in Animals and Animal Products NY / T 1897-2010", and "Sampling Specifications for Aquatic Products GB / T30891-2014" all put forward specific requirements for sampling work to ensure the standardization of the sampling process. Relevant standards also have clear provisions on the weight, preparation, packaging, coding, and storage of samples.

[0003] In actual work, agricultural product sampling work all takes place at outdoor breeding bases. Due to the limitations of the site environment, most agricultural product sampling work can only be done according to local conditions, overcome difficulties, and prepare as many tools and materials as possible to ensure the smooth progress of sampling work. In order to ensure the smooth progress of agricultural product sampling work, at least two people are generally required to work at the same time. The most time-consuming part of the sampling process is the sample extraction link, which includes sample picking, fishing time and sample preparation time. In the sample preparation link, one person is responsible for sorting samples, shrinking and crushing samples, and cleaning crushing equipment; the other person is responsible for coding, packaging, and packaging samples. In actual measurement at work, two staff members carry out on-site preparation of vegetable and fruit samples, and can prepare 10 to 15 samples in half a day; two staff members carry out on-site preparation of aquatic product samples or livestock and poultry samples, and can prepare 5 to 10 samples in half a day, which is less efficient. In addition, due to manual operation, the packaging process may also result in insufficient sample weight, coding errors, blurred and unrecognizable handwriting, uneven sample packaging, and sample liquid leakage and contamination.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The sampling process in the sampling work is affected by many factors such as the site, season, climate, etc., and is more affected by uncontrollable factors. Due to the particularity of the test samples, the test samples cannot interfere with each other or contaminate each other, which puts high requirements on the on-site preparation of the test samples, so it is difficult to compress time and improve efficiency. The weighing, coding and packaging work in the preparation process has relatively clear steps, so it is feasible to realize automation. In addition, if the weighing, coding and packaging of samples are automated, it will save about half of the manpower, and it can be more accurately grasp the weight of the samples, accurately code, and accurately package the samples into multiple copies without leakage or pollution, greatly improving the efficiency and reliability of sample preparation. The packaging of samples after automated packaging is more standardized and normalized, which is more conducive to docking laboratory testing automation.

[0041] In order to solve the above technical problems, the present invention proposes a test sample weighing, coding and packaging system, which automatically controls the weighing, coding, packaging and other links of the test samples through a programmable logic controller and a preset algorithm, can accurately weigh the quality of the test samples, and automatically encode and package the test samples; can greatly reduce labor costs, improve the quality of test sample packaging, and prevent sample contamination, and is suitable for various scenario requirements such as on-site sample preparation, laboratory sample preparation, and supervised random inspection sample preparation.

[0042] The following describes a sample weighing, coding and packaging system according to an embodiment of the present invention with reference to the accompanying drawings.

[0043] like Figures 1 to 11 As shown, the sample weighing, coding and packaging system of the embodiment of the present invention includes: a control box unit 1 and an automatic operation box unit 2, and the control box unit 1 is located at the rear of the automatic operation box unit 2.

[0044] like Figure 1 As shown, the control box unit 1 includes a programmable logic controller 11, a power control module 12 and a heat dissipation window 13, and the heat dissipation window 13 can be used to dissipate heat for the control box unit 1 in a timely manner.

[0045] like Figure 2As shown, the outside of the automated operation box unit 2 is provided with a sample inlet 2A, a touch screen 2B, an emergency stop button 2C, a label outlet 2D, a material outlet 2E and a universal wheel 2F. The inspector puts the test sample into the test sample weighing and coding packaging system through the sample inlet 2A, and performs relevant control operations through the touch screen 2B. When the system is abnormal, the system can be shut down by pressing the emergency stop button 2C.

[0046] like Figure 3 As shown, the interior of the automated operation box unit 2 is provided with a weighing module 21, a packaging module 22, a coding module 23 and a conveying module 24, wherein the weighing module 21 is used to weigh the test sample, wherein the test sample is suitable for being placed in the sample bag 3; the packaging module 22 is used to vacuum the weighed test sample and to package it according to a preset number of samples; the coding module 23 is used to encode the packaged test sample and print the code; the conveying module 24 is used to transport the packaged test sample to the material taking port 2E.

[0047] The programmable logic controller 11 is connected to the weighing module 21, the packaging module 22, the encoding module 23 and the conveying module 24 respectively, and is used to obtain the signal of the weighing module 21, and control the weighing module 21, the packaging module 22, the encoding module 23 and the conveying module 24. The power control module 12 is externally connected to the mains, and is used to power the weighing module 21, the packaging module 22, the encoding module 23, the conveying module 24 and the touch display screen 2B.

[0048] Specifically, when testing the test sample, the inspector first enters the sample matrix information, sample coding information and grouping information into the programmable logic controller 11 in advance, and puts the sample bag 3 containing the test sample on the hook of the weighing module 21 through the sample inlet 2A, then closes the sample inlet 2A, clicks the run button displayed on the touch screen 2B, and the weighing module 21 feeds back the sample quality information to the programmable logic controller 11, and the programmable logic controller 11 judges the sample weight according to the sample matrix and other information. If the sample weight meets the requirements, the touch screen 2B displays the actual weight information of the sample. After weighing, when the quality of the test sample meets the test requirements, the packing module 22 is closed, and the air in the sample bag 3 is extracted. According to the preset number of sample copies, the packing module 22 performs longitudinal packaging cutting and transverse packaging cutting on the sample bag 3. After the packing module 22 is opened, the packaged sample naturally falls to the conveying module 24 and is conveyed to the material taking port 2E.

If not, press the reset button on the touch screen 2B to initialize each module and ensure that the weighing slider 216 is at the lower end of the slide rail 217. Then hang the sample bag 3 containing the test sample on the crossbar hook 215. The weighing sensor 212 weighs the test sample and feeds back the sample quality information to the programmable logic controller 11. The programmable logic controller 11 judges the sample weight based on information such as the sample matrix.

[0064] Example 1: When sampling a batch of Chinese cabbage, the inspector first enters the sample matrix information Chinese cabbage, sample code information 2023NCP-CJ-083 and three copies of grouping information into the programmable logic controller 11 in advance, and then checks whether each module is in the initial state. If not, press the reset button on the touch screen 2B to initialize each module, ensure that the weighing slider 216 is located at the lower end of the slide rail 217, and then hang the sample bag 3 containing the test sample on the crossbar hook 215, so that the sample bag 3 is flatly placed between the sub-packaging fixed component 221 and the sub-packaging movable component 222. Then, the inspector closes the sample inlet 2A and clicks the run button displayed on the touch screen 2B. The weighing module 21 feeds back the sample quality information to the programmable logic controller 11, and the programmable logic controller 11 judges the sample weight according to the sample matrix and other information. If the sample weight does not meet the requirements, the touch screen 2B displays an alarm message, and the inspector replenishes the sample amount and clicks the touch screen 2B run button again. The weighing module 21 weighs the sample weight greater than the requirement, and the touch screen 2B displays the actual weight information of the sample (700g). After weighing, the horizontal electric push rod 2226 in the subpackaging movable component 222 is started, and the air extraction port 2212 in the subpackaging fixed component 221 is closed to extract the air in the sample bag 3. Two groups of longitudinal electric push rods 2227 are started to push the two groups of longitudinal movable devices 2223 and the transverse plastic sealing block 2213 in the subpackaging fixed component 221 to close.

Open the lateral movable device 2222 and the longitudinal movable device 2223, and according to the preset algorithm in the programmable logic controller 11, start the slider electric push rod 218 to lift the sample bag 3 to the preset height. Start the lateral electric push rod 2226 again, push the lateral movable device 2222 and the module fixing assembly to close, start the lateral plastic sealing block 2213 to heat the plastic sealing, and start the lateral cutting wire 2214 to cut. Start the lateral electric push rod 2226 to remove the lateral movable device 2222. The packaged samples naturally fall to the conveying module 24 and are transported to the sample collection box 243. The encoding module 23 prints the sample information label and outputs it from the label outlet 2D. The sample information includes but is not limited to the sample name (Chinese cabbage), sample number (2023NCP-CJ-083), sample grouping information (one positive sample, one sub-sample, and one retained sample), and the actual weight of the sample after grouping (210g±30g). The inspector takes out the packaged samples and manually sticks the labels to the packaged samples.

[0065] Example 2: The inspector first enters the sample matrix information pork, sample code information 2023XCP-CJ-121 and four copies of grouping information into the programmable logic controller 11 in advance, and then checks whether each module is in the initial state. If not, press the reset button on the touch screen 2B to initialize each module, ensure that the weighing slider 216 is at the bottom of the slide rail 217, and then hang the sample bag 3 containing the test sample on the crossbar hook 215, so that the sample bag 3 is flat between the sub-packaging fixed component 221 and the sub-packaging movable component 222. The inspector closes the sample inlet 2A and clicks the run button displayed on the touch screen 2B. The weighing module 21 feeds back the sample quality information to the programmable logic controller 11, and the programmable logic controller 11 judges the sample weight according to the sample matrix and other information. If the sample weight meets the requirements, the touch screen 2B displays the actual sample weight information (900g). After weighing, the transverse electric push rod 2226 in the packaging movable component 222 is started, pushing the transverse movable device 2222 and the air extraction port 2212 in the packaging fixed component 221 to close, and extracting the air in the sample bag 3. At the same time, the three groups of longitudinal electric push rods 2227 are started to push the two groups of longitudinal movable devices 2223 and the transverse plastic sealing block 2213 in the packaging fixed component 221 to close. The longitudinal plastic sealing block 2215 is started to heat and seal, and the longitudinal cutting wire 2216 is started to cut. The transverse movable device 2222 and the longitudinal movable device 2223 are opened, and according to the preset algorithm in the programmable logic controller 11, the slider electric push rod 218 is started to lift the sample bag 3 to a preset height. The transverse electric push rod 2226 is started again to push the transverse movable device 2222 and the packaging fixed component 221 to close, the transverse plastic sealing block 2213 is started to heat and seal, and the transverse cutting wire 2214 is started to cut. The transverse electric push rod 2226 is started to remove the transverse movable device 2222. The packaged samples naturally fall onto the conveying module 24 and are transported to the sample collection box 243. The encoding module 23 prints the sample information label and outputs it from the label outlet 2D. The sample information includes but is not limited to the sample name (pork), sample number (2023XCP-CJ-121), sample grouping information (one positive sample, one duplicate sample, two reserved samples), and the actual weight of the sample after grouping (220g±30g). The inspector takes out the packaged samples and manually sticks the labels on the packaged samples.

[0066] In summary, according to the detection sample weighing coding and packaging system of the embodiment of the present invention, when the detection sample is detected, the inspector first enters the sample matrix information, sample coding information and grouping information into the programmable logic controller in advance, and puts the sample bag containing the detection sample on the hook of the weighing module through the injection port, and then closes the injection port, clicks the run button displayed on the touch screen, and the weighing module feeds back the sample quality information to the programmable logic controller, and the programmable logic controller judges the sample weight according to the information such as the sample matrix, and the sample weight meets the requirements, and the touch screen displays the actual weight information of the sample. After weighing, when the quality of the detection sample meets the detection requirements, after the packaging module is closed, the air in the sample bag is extracted, and according to the preset sample number, the packaging module performs longitudinal packaging cutting and transverse packaging cutting and packaging on the sample bag. After the packaging module is opened, the packaged sample naturally falls to the conveying module and is conveyed to the material taking port. At the same time, the coding module prints the corresponding number of copies and the coded labels for the inspector to post and use. Thus, the system can ensure that the sample quality of the test sample meets the requirements when preparing the sample, and prevent the situation that the quality of the test sample does not meet the test requirements; various information of the test sample can be accurately coded to prevent various errors and omissions caused by unclear handwriting on site; automatic extrusion grouping can be achieved; full-process closed operation can be achieved to prevent the sample from leaking and contaminating; with standardized packaging capabilities, the sample after packaging can be directly connected to the laboratory test automation.
