Description

Technical Field

[0001] The invention relates to the technical field of total moisture testing, and in particular to a sample tray scheduling and total moisture testing method. Background Art

[0002] During the full moisture test, in order to improve the experimental efficiency, multiple samples are usually placed in an oven, but the moisture values ​​of different samples vary greatly, and the required drying time is also different, usually 1.5h-3h. Before the samples are placed in the oven, they need to go through processes such as sample reception and shrinking. This process takes about 10min-15min, and the transfer robot needs to put the shrunken samples into the oven in order; and there is uncertainty in the sample reception time, which may cause the coexistence of samples that have been dried and new samples in the oven. After the sample is dried and enters the inspection drying process, if a new high-moisture sample is subsequently placed in the same oven, the humidity in the oven will increase rapidly due to the rapid release of external water, causing the dried sample to absorb water, affecting the inspection drying process and causing deviations in the test results. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a sample tray scheduling method with high test accuracy and high drying efficiency, and provide a total moisture testing method with high test accuracy, high equipment utilization and strong adaptability.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A sample plate scheduling method comprises the following steps: Step S1: After the sample tray receives the test sample, determine whether there is an oven with a vacant space in the oven module. If yes, proceed to step S2; if not, wait until an oven with a vacant space appears. Step S2, determining whether there is a sample plate in the inspection drying process in the vacant oven, if yes, proceeding to step S3, if not, proceeding to step S4; Step S3, transferring the sample tray in the inspection drying process to another oven that also has sample trays in the inspection drying process, and returning to step S2; Step S4: placing the sample plate in an oven for drying.

[0005] After step S4, the following steps are also included: Step S5, determining whether the drying time set by the system has been reached, if yes, proceeding to step S6, if no, continuing drying until the set drying time is reached; Step S6, transport the sample plate to the weighing station for weighing, and determine whether inspection drying is required. If yes, proceed to step S7, if not, proceed to step S8; Step S7, transport the sample plate back to the oven, continue drying, and return to step S5; Step S8: clean and recycle the sample tray.

[0006] The step S8 specifically includes the following steps: Step S81, transporting the sample plate to a cleaning station for cleaning; Step S82, determine whether there is an empty space on the sample tray storage rack. If so, transfer the cleaned sample tray to the sample tray storage rack for storage. If not, transfer the cleaned sample tray to the drying oven for temporary storage.

[0007] In step S1, the oven module includes a plurality of ovens, and a plurality of drying stations are provided in the ovens.

[0008] A total moisture testing method comprises the following steps: Step S100, transporting the sample bottle containing the sample to the shrinking station; Step S101, the sample is reduced at the reduction station into a test sample and a reserve sample. The test sample is divided into two parts and received by two sample trays respectively, and the reserve sample is received by an empty sample bottle that has completed feeding; Step S102, determine whether parallel sample testing is required, if yes, proceed to step S103, if no, proceed to step S106; Step S103, flatten and weigh the two sample trays respectively, use the above-mentioned sample tray scheduling method to schedule the sample trays to dry and weigh the test samples, and calculate the total moisture values ​​of the two test samples; Step S104, judging whether the moisture results of the two parallel samples are out of tolerance, if yes, proceeding to step S105, if no, the test ends; Step S105, start the redo process, transfer the sample bottle containing the prepared sample to the reduction station, and return to step S101; Step S106, flatten and weigh one sample tray, use the above-mentioned sample tray scheduling method to schedule the sample tray to dry and weigh the test sample, and calculate the total moisture value of the test sample; clean and recycle the other sample tray.

[0009] After step S106, the method further includes the following steps: Step S107, determine whether there is a total moisture value output, if yes, the test ends, if not, go to step S105.

[0010] Before step S105, it is also necessary to determine whether the sample weight is greater than the minimum reduced input weight supported by the system. If so, proceed to step S105. If not, notify manual intervention and the test ends.

[0011] The sample weight m5 It is calculated in the following way: m 5 =m 0 -m 1 -m 2 -m 3 ; or m 5 =m 4 -m 3 ; Among them, m 0 is the weight of the sample bottle containing the sample; m 1 、m 2 are the weights of the test samples in the two sample pans, m 3 is the weight of the sample bottle; m 4 is the weight of the sample bottle containing the prepared sample.

[0012] In step S105, the test sequence priority of the sample bottle containing the prepared sample is set to the highest.

[0013] In step S102, it is determined whether parallel sample testing is required according to system settings or external instructions.

The sample tray scheduling method of the present invention transfers the sample trays in the inspection drying process to other ovens that also have sample trays in the inspection drying process for centralized drying. This can avoid placing subsequent high-moisture samples in the same oven as the samples undergoing inspection drying. The test accuracy is high, and each station of each oven can be fully utilized, resulting in high drying efficiency.

[0015] 2. The sample tray scheduling method of the present invention reduces the demand for empty sample tray storage space and the volume of the sample tray storage rack by utilizing an oven to temporarily store empty sample trays; moreover, the sample trays are preferentially stored in the sample tray storage rack, thereby improving the utilization rate of the sample tray storage rack.

[0016] 3. The total moisture test method of the present invention, by transferring the sample tray in the inspection drying process to other ovens that also have sample trays in the inspection drying process for centralized drying, can avoid placing the subsequent high-moisture samples in the same oven as the samples undergoing inspection drying, and the test accuracy is high; by dividing the samples that have been reduced into test samples and backup samples, and saving the backup samples for future reference, when the test results are abnormal (for example, the results of the two samples are out of tolerance), the backup samples can be tested again, and the test accuracy is higher; by recycling the empty sample bottles that have completed the feeding for backup samples, the sample bottles can be reused, the equipment utilization rate is high, and the cost is low; by dividing the test sample into two parallel test samples, the two test samples can verify the results with each other, the test accuracy is higher, and the single and double sample tests can be switched according to actual needs. In some scenarios, parallel samples may not be required to improve test efficiency and reduce energy consumption, and the adaptability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "assemble", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1: like Figure 1 As shown, the sample disk scheduling method of this embodiment includes the following steps: Step S1: After the sample tray receives the test sample, determine whether there is an oven with a vacant space in the oven module. If yes, proceed to step S2; if not, wait until an oven with a vacant space appears. Step S2, determining whether there is a sample plate in the inspection drying process in the vacant oven, if yes, proceeding to step S3, if not, proceeding to step S4; Step S3, transferring the sample tray in the inspection drying process to another oven that also has sample trays in the inspection drying process, and returning to step S2; Step S4: placing the sample plate in an oven for drying.

[0024] The sample tray scheduling method of this embodiment transfers the sample trays in the inspection drying process to other ovens that also have sample trays in the inspection drying process for centralized drying. This can avoid placing subsequent high-moisture samples in the same oven as the samples undergoing inspection drying. The test accuracy is high, and each station in each oven can be fully utilized, resulting in high drying efficiency.

[0025] Furthermore, in this embodiment, after step S4, the following steps are also included: Step S5, determining whether the drying time set by the system has been reached, if yes, proceeding to step S6, if no, continuing drying until the set drying time is reached; Step S6, transport the sample plate to the weighing station for weighing, and determine whether inspection drying is required. If yes, proceed to step S7, if not, proceed to step S8; Step S7, transport the sample plate back to the oven, continue drying, and return to step S5; Step S8: clean and recycle the sample tray.

[0026] By weighing the sample pan that has reached the set drying time and ensuring that the sample pan has a constant weight, and then cleaning and recycling it, the test accuracy is higher.

[0027] Furthermore, in this embodiment, step S8 specifically includes the following steps: Step S81, transporting the sample plate to a cleaning station for cleaning; Step S82: determine whether there is an empty space on the sample tray storage rack. If yes, transfer the cleaned sample tray to the sample tray storage rack for storage. If not, transfer the cleaned sample tray to the drying oven for temporary storage. By using the drying oven to temporarily store empty sample trays, the demand for empty sample tray storage space is reduced, and the volume of the sample tray storage rack is reduced; and the sample trays are stored in the sample tray storage rack first, thereby improving the utilization rate of the sample tray storage rack.

[0028] Furthermore, in this embodiment, in step S1, the oven module includes a plurality of ovens, and a plurality of drying stations are provided in the ovens, so that sample plates in different states can be dried at the same time, and the drying efficiency is high.

[0029] Preferably, in this embodiment, the number of sample tray storage positions of the sample tray storage rack is greater than the number of drying positions of a single oven, so that when the sample tray storage rack is full, at least one oven is vacant and can be preheated in advance, resulting in higher drying efficiency.

[0030] Embodiment 2: like Figure 2 As shown, the full moisture testing method of this embodiment includes the following steps: Step S100, transporting the sample bottle containing the sample to the shrinking station; Step S101, the sample is reduced at the reduction station into a test sample and a reserve sample. The test sample is divided into two parts and received by two sample trays respectively, and the reserve sample is received by an empty sample bottle that has completed feeding; Step S102, determine whether parallel sample testing is required, if yes, proceed to step S103, if no, proceed to step S106; Step S103, flattening and weighing the two sample trays respectively, using the sample tray scheduling method of Example 1 to schedule the sample trays to dry and weigh the test samples, and calculating the total moisture values ​​of the two test samples; Step S104, judging whether the moisture results of the two parallel samples are out of tolerance, if yes, proceeding to step S105, if no, the test ends; Step S105, start the redo process, transfer the sample bottle containing the prepared sample to the reduction station, and return to step S101; Step S106, flatten and weigh one sample tray, and use the sample tray scheduling method of Example 1 to schedule the sample tray to dry and weigh the test sample, and calculate the total moisture value of the test sample; clean and recycle the other sample tray.

[0031] The full moisture test method of this embodiment, by transferring the sample tray in the inspection drying process to other ovens that also have sample trays in the inspection drying process for centralized drying, can avoid placing the subsequent high-moisture samples in the same oven as the samples undergoing inspection drying, and the test accuracy is high; the samples that have been shrunk are divided into test samples and backup samples, and the backup samples are stored for reference. When the test results are abnormal (for example, the results of the two samples are out of tolerance), the backup samples can be tested again, and the test accuracy is higher; the empty sample bottles that have completed the feeding are recycled to receive the backup samples, the sample bottles can be reused, the equipment utilization rate is high, and the cost is low; the test sample is divided into two parallel test samples, the two test samples can verify the results with each other, the test accuracy is higher, and the single and double sample tests can be switched according to actual needs. In some scenarios, parallel samples may not be required to improve test efficiency and reduce energy consumption, and the adaptability is strong.

[0032] Furthermore, in this embodiment, after step S106, the following steps are also included: Step S107, determine whether there is a total moisture value output, if yes, the test ends, if not, go to step S105. When the test result is abnormal (for example, the single sample test result is not output normally), the spare sample can be tested again, and the test accuracy is higher.

[0033] Furthermore, in this embodiment, before step S105, it is necessary to determine whether the weight of the prepared sample is greater than the minimum weight of the reduced material supported by the system. If so, step S105 is entered. If not, manual intervention is notified and the test ends. By determining whether the weight of the prepared sample is greater than the minimum weight of the reduced material supported by the system, the prepared sample that does not meet the national standard full water sample weight requirement is prevented from being reduced, thereby reducing the test efficiency.

[0034] Furthermore, in this embodiment, the sample weight m 5 It is calculated in the following way: m 5 =m 0 -m 1 -m 2 -m 3 ; (1) or m 5 =m 4 -m 3 ; (2) Among them, m 0 is the weight of the sample bottle containing the sample; m 1 、m 2 are the weights of the test samples in the two sample pans, m 3 is the weight of the sample bottle; m 4 is the weight of the sample bottle containing the prepared sample.

[0035] In the double sample test, both sample pans are weighed, and the sample weight m can be calculated using formula (1). 5 When testing a single sample, since the other sample tray is cleaned and recycled, the weight of the prepared sample m can be calculated using formula (2). 5 The calculation process is simple and reliable.

[0036] Furthermore, in this embodiment, in step S105, the test sequence priority of the sample bottle containing the spare sample is set to the highest. When the test result is abnormal, the test can be quickly redone and the cause of the abnormality can be found in time by adjusting the priority.

[0037] Furthermore, in this embodiment, in step S102, it is determined whether parallel sample testing is required according to system settings or external instructions. When the total moisture value is used as a key indicator (such as trade settlement, dispute arbitration), parallel samples are required to reduce random errors and ensure the reliability of the test results; if the total moisture value is only used as an auxiliary indicator, parallel samples may not be required to improve test efficiency and reduce energy consumption.

[0038] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above in the preferred embodiment, it is not used to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above without departing from the spirit and technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention, still fall within the scope of protection of the technical solution of the present invention.
