Description

Technical Field

[0001] The invention relates to the technical field of material sampling, and more specifically, to a method for sampling incoming rail-transported materials. Background Art

[0002] In recent years, with the continuous increase in the company's production, the demand for purchased raw materials and auxiliary materials has continued to increase, resulting in huge pressure on the company's railway transportation. The raw materials and auxiliary materials transported by rail must be sampled for quality inspection before unloading. There are three reasons: First, since the train receiving trough is a mixed use of multiple varieties, sampling after unloading will cause secondary pollution and affect the true results of the samples; second, due to the influence of the material yard, it is impossible to stack them separately, and the samples taken after mixing are not representative; third, sampling after unloading cannot meet the requirements of return if major quality problems are found.

[0003] At present, manual sampling is time-consuming and laborious, which seriously affects the company's train transportation efficiency and production. In addition, there are also great safety hazards and fraud risks in the manual sampling operation. The details are as follows:

[0004] 1. Manual sampling is time-consuming and labor-intensive, and the sampling operation is time-consuming, which seriously affects the efficiency of train transportation and production;

[0005] 2. Manual sampling has great safety hazards. First, there is a risk of falling and getting injured during the climbing process; second, personnel entering the railway to work may cause vehicle injury accidents;

[0006] 3. Manual sampling is feasible and there is a possibility of intentionally avoiding sampling of inferior materials, which is not conducive to the company's counterfeiting management. Summary of the invention

[0007] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. The purpose of the present invention is to provide a method for sampling incoming rail-transported materials to improve efficiency, increase safety and reduce the risk of fraud.

[0008] The technical solution of the present invention is: a method for sampling incoming rail-transported materials, comprising the following steps:

[0009] Step 1. The Marketing Department should prepare the forecast of railway transportation information;

[0010] Step 2. The logistics center completes the rail transport information entry work according to the rail transport information from the marketing department;

[0011] Step 3. The railway dispatching department of the logistics center instructs the train to stop within the effective sampling range of the train automatic sampler;

[0012] Step 4. After the vehicle is assigned, the Railway Dispatching Department of the Logistics Center notifies the Quality Inspection Department to take samples and informs the Quality Inspection Department of the sampling information in detail;

[0013] Step 5. After receiving the sampling notice, the quality inspection department checks the sampling information and batches, and the quality inspection personnel print the sampling barcode and go to the site for sampling;

[0014] Step 6. After the quality inspectors arrive at the sampling site, they will first check the physical information, check whether the material name is consistent with the actual object, check whether the number of sampling cards is consistent with the actual situation, and check the surface quality of the carriage materials; if it is found that the system sampling information is inconsistent with the actual situation, or other quality abnormalities are found, sampling will be stopped immediately, and relevant units will be organized to jointly handle the situation on site. Sampling operations can only be continued after the handling results are consistent;

[0015] Step 7. Prepare before sampling operation, clean the drill bit with the original sample, and set the sampling rules;

[0016] Step 8. The train automatic sampling machine performs vehicle identification and positioning;

[0017] Step 9. After the vehicle identification and positioning is completed, the sampling program is started to start sampling;

[0018] Step 10. During the sampling process, you need to pay close attention to the operation of the equipment and the quality of the materials;

[0019] Step 11. Single sampling is completed and samples are packaged and collected;

[0020] Step 12. Notify the railway dispatching department to locate the next carriage by trailer, repeat steps 8 to 12 until all sampling is completed, the train automatic sampler is reset, and the equipment is cleaned and maintained.

[0021] As a further improvement, the rail transport information entering the factory includes the date, time, card number, car number, material name, and supplier. The logistics center will enter the rail transport information into the company's quality management system.

[0022] Furthermore, the sampling information includes unit, product name, and card number.

[0023] Furthermore, the surface quality of the carriage material includes at least one of color, abnormal particle size, impurities, and water accumulation.

[0024] Furthermore, setting sampling rules includes:

[0025] Fully automatic definition, the operator fills in the sampling rules, selects the sample quantity gear, selects fully automatic, starts the program, and the train automatic sampler automatically completes the train departure, position selection, sampling, rising, hopper extension, unloading, and shrinking. After shrinking, part of the sample enters the hopper, and the other part falls back to the train car. Fully automatic sampling can realize multi-point and multi-carriage linkage;

[0026] Semi-automatic definition: the operator fills in the sampling rules, selects the sample quantity gear, selects semi-automatic, and manually drives the train automatic sampler to the position of the carriage where sampling is required, starts the program, and the drill goes down, rises, the receiving hopper extends, unloads, and shrinks. After the shrinkage, part of the sample enters the receiving hopper, and part falls back to the train carriage. Semi-automatic sampling can only be done by single sampling and single unloading, and cannot be linked to multiple points or multiple carriages. Manual control of the point location is required. Semi-automatic sampling is mainly used for targeted quality spot checks when most surface quality abnormalities are found;

[0027] Sampling rules: when the number of carriages is ≤5, randomly select 2 carriages and take 3 points from each carriage; when the number of carriages is 6 and the number of carriages is ≤10, randomly select 6 carriages and take 2 points from each carriage; when the number of carriages is ≥16, randomly select 8 carriages and take 1 point from each carriage;

[0028] Sample quantity requirements: powder ore / ≥20Kg; lump ore / ≥30Kg; coal and coke powder ≥18Kg;

[0029] The sample quantity is controlled by a telescopic material receiving device, which is divided into three gears: high, medium and low.

[0030] Furthermore, the reduction is divided into three levels: high, medium and low, corresponding to 3 / 4, 1 / 2 and 1 / 3 respectively.

[0031] Furthermore, vehicle identification and positioning requires identification of the X, Y, and Z coordinate axes of the carriage, where the X axis represents the width of the carriage, the Y axis represents the length of the carriage, and the Z axis represents the height of the material in the carriage, as follows:

[0032] X-axis carriage width, using the train track to define the X-axis, that is, the drill bit travels to the center of the track as the 0 point, and the left and right deviations are positive and negative distances. After the carriage width is set, the recognition system of the train automatic sampler automatically recognizes the sampling position;

[0033] Y-axis car length, use the first car or the last car to define the Y-axis, and read through the infrared sensor. No matter sampling from front to back or from back to front, the first time the sensor senses is 0, and the forward and backward movements are positive and negative distances respectively. Set the hook distance and length between the cars, and the recognition system automatically recognizes the car and sampling position;

[0034] Z-axis carriage material height, the carriage floor and material probe are used to define the Z-axis; the carriage floor height is 0 point, upward is the positive distance, and a 10 cm safety distance is reserved. The part above is the sampling range of the drill bit; the material loading height is obtained through the material probe. During the sampling process of the sampling head, the material probe and the sampling head drop together. When the material probe touches the material surface, the system starts counting from 0, and downward is a negative number. Subtracting the carriage floor height is equal to the material thickness, that is, the sampling depth range. Set the carriage floor height, and the recognition system automatically recognizes the sampling depth;

[0035] The sampling position and depth are randomly generated by the system to ensure that no less than 3 deep points are sampled each time. The deep point is defined as: the position where the drill bit reaches 10 cm above the 0 point on the floor of the carriage;

[0036] The train carriages are uniformly C80 type carriages with fixed length, width and floor height;

[0037] The train automatic sampler adopts existing mature products. The train automatic sampler mainly includes a trolley, a small car, a drill lifting device, a drill, a central control machine, and a sampling system. The movement of the trolley is the X-axis, the movement of the trolley is the Y-axis, and the lifting of the drill is the Z-axis.

[0038] Beneficial Effects

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] 1. The present invention solves the problem that the existing manual sampling operation of climbing a train is time-consuming and labor-intensive, seriously affecting the company's train transportation efficiency, affecting production, and there are also major safety hazards and fraud risks in the manual sampling operation process.

[0041] 2. It improves the sampling efficiency of incoming rail transport materials, reduces the company's train transportation pressure, and avoids the situation where the unloading and production of rail transport materials are affected by time-consuming and labor-intensive sampling.

[0042] 3. Reduce the labor intensity of manual sampling and release manpower.

[0043] 4. Reduces manual operation safety and fraud risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION

[0045] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0046] See also Figure 1 A method for sampling incoming rail transport materials includes the following steps 1 to 12:

[0047] Step 1. The Marketing Department shall prepare forecasts for rail transport information entering the factory, which shall include the date, time, card number, carriage number, material name, and supplier.

[0048] Step 2. The logistics center completes the rail transportation information entry work according to the marketing department's rail transportation information, and enters the date, time, card number, car number, material name, and supplier information into the company's quality management system.

[0049] Step 3. The railway dispatching department of the logistics center instructs the train to stop within the effective sampling range of the train automatic sampler. Sampling cannot be performed if the train stops outside the effective sampling range.

[0050] Step 4. After the vehicle is assigned, the Railway Dispatching Department of the Logistics Center notifies the Quality Inspection Department to take samples and informs the Quality Inspection Department of the sampling information in detail. The sampling information includes the unit, product name, and number of cards.

[0051] Step 5. After receiving the sampling notice, the Quality Inspection Department will check the sampling information and group the batches. The same unit, the same product name, and the same day (8:00-8:00 the next day) will be grouped as one batch. The quality inspection personnel will print the sampling barcode and go to the site for sampling. The sampling barcode contains the sampling information.

[0052] Step 6. After the quality inspectors arrive at the sampling site, they will first check the physical information, check whether the material name is consistent with the actual object, check whether the number of sampling cards is consistent with the actual situation, and check the surface quality of the carriage materials. The surface quality of the carriage materials includes at least one of the following: color, abnormal particle size, impurities, and water accumulation. If it is found that the system sampling information is inconsistent with the actual situation, or other quality abnormalities are found, sampling will be stopped immediately, and relevant units will be organized to jointly handle the situation on site. Sampling operations can only be continued after the handling results are consistent.

[0053] Step 7. Prepare before sampling operation, clean the drill bit with the original sample, set the sampling rules, including:

[0054] 1) Fully automatic definition: the operator fills in the sampling rules, selects the sample quantity gear, selects fully automatic, and starts the program. The train automatic sampler automatically completes the process of leaving the train (the sampling machine trolley and the sampling trolley leave the initial position), selecting the location (point layout), sampling (the drill bit enters the carriage to sample the depth), rising (the drill bit rises), the hopper extends, the material is discharged (the sampling head discharges the material into the hopper), and the reduction is divided into three gears: high, medium, and low, corresponding to 3 / 4, 1 / 2, and 1 / 3 respectively. After the reduction, part of the sample enters the hopper, and the other part falls back to the train carriage. Fully automatic sampling can realize multi-point and multi-carriage linkage.

[0055] 2) Semi-automatic definition: the operator fills in the sampling rules, selects the sample quantity gear, selects semi-automatic, and manually drives the train automatic sampler to the position of the carriage where sampling is required. The program is started, and the drill bit goes down, rises, the receiving hopper extends, unloads, and shrinks. The shrinkage is divided into three gears: high, medium, and low, corresponding to 3 / 4, 1 / 2, and 1 / 3 respectively. After the shrinkage, part of the sample enters the receiving hopper, and part falls back to the train carriage. Semi-automatic sampling can only be done for single sampling and single unloading, and cannot be linked to multiple points or multiple carriages. Manual control of the point location is required. Semi-automatic sampling is mainly used for most of the surface quality abnormalities (such as color and particle size abnormalities) for targeted quality spot checks.

[0056] 3) Sampling rules: when the number of carriages is ≤5 cars, randomly select 2 cars and take 3 points from each car; when the number of carriages is 6 cars≤the number of carriages is ≤10 cars, randomly select 6 cars and take 2 points from each car; when the number of carriages is ≥16 cars, randomly select 8 cars and take 1 point from each car.

[0057] 4) Sample quantity requirements: powder ore / ≥20Kg; lump ore / ≥30Kg; coal and coke powder ≥18Kg.

[0058] 5) Sample quantity control is controlled by a telescopic material receiving device, which is divided into three gears: high, medium and low. It is set according to different materials (such as powdered materials, block materials, dry materials and wet materials). For example, high, medium and low correspond to 3 / 4, 1 / 2 and 1 / 3 respectively.

[0059] Step 8. The train automatic sampler performs vehicle identification and positioning. Vehicle identification and positioning require the identification of the X, Y, and Z coordinate axes of the carriage, where the X axis represents the width of the carriage, the Y axis represents the length of the carriage, and the Z axis represents the height of the carriage material, i.e., the sampling depth. The details are as follows:

[0060] 1) X-axis carriage width: The X-axis is defined by the train track, that is, the drill bit travels to the center of the track (which is also the center of the carriage) as the 0 point, and the left and right deviations are positive and negative distances. After the carriage width is set, the recognition system of the train automatic sampler automatically identifies the sampling position.

[0061] 2) Y-axis car length. Use the first car or the last car to define the Y-axis and take readings through an infrared sensor. Regardless of sampling from front to back or from back to front, the first time the sensor senses is zero. The forward and backward movements are positive and negative distances, respectively. Set the hook distance and length between the cars. The recognition system automatically identifies the cars and sampling positions.

[0062] 3) Z-axis carriage material height, i.e., sampling depth, uses carriage floor and material probe to define Z-axis; carriage floor height is 0 point, upward is positive distance, 10 cm safety distance is reserved, and the above part is the sampling range of the drill bit. The material loading height is obtained through the material probe (i.e., sensor), and the material probe and sampling head descend together during the sampling process. When the material probe touches the material surface, the system starts counting from 0, and downward is negative. Subtracting the carriage floor height is equal to the material thickness, which is the range of sampling depth. Set the carriage floor height (i.e., the distance from the track to the carriage floor), and the recognition system automatically identifies the sampling depth.

[0063] 4) The sampling position and depth are randomly generated by the system to ensure that no less than 3 deep points are sampled each time. The deep point is defined as the position where the drill bit reaches 10 cm above the 0 point on the floor of the carriage. The deep point is a safe position.

[0064] 5) Train carriages are uniformly C80 type carriages with fixed length, width and floor height.

[0065] 6) The train automatic sampler adopts existing mature products, such as MCY-HQCLX22 train sampler and ZDHC train sampler. The train automatic sampler mainly includes a trolley, a small car, a drill lifting device, a drill, a central control machine and a sampling system. The trolley travels as the X-axis, the trolley travels as the Y-axis and the drill lifting is the Z-axis.

[0066] Step 9. After vehicle identification and positioning are completed, start the sampling program to begin sampling.

[0067] Step 10. During the sampling process, it is necessary to pay close attention to the operation of the equipment (including the drill bit operation trajectory, sampling points and other abnormal conditions), and pay attention to the quality of the materials (including abnormal conditions such as impurities, stratification, mixing, and inferior products).

[0068] Step 11. Single sampling is completed and the samples are packaged and collected.

[0069] Step 12. Notify the railway dispatching department to locate the next carriage by trailer, repeat steps 8 to 12 until all sampling is completed, the train automatic sampler is reset, and the equipment is cleaned and maintained.

[0070] According to the present invention, after the vehicle arrives at the sampling line, the sampling personnel complete the input of sampling information, firstly, retrieve the train number to be sampled from the company's quality system, then fill in the sampling rules, and finally select the sampling method. After confirmation, the sampling program is started to start the automatic sampling of the whole process. Through mechanized and intelligent operation, the purpose of fast and automatic sampling of rail transport materials is achieved, which solves the problem that the existing manual climbing car sampling operation is time-consuming and labor-intensive, seriously affects the company's train transportation efficiency, affects production and there are still large safety hazards and fraud risks in the manual sampling operation process.

[0071] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
