Description

Technical Field

[0001] This utility model relates to an online sampling device for process equipment, belonging to the field of tobacco processing technology. Background Technology

[0002] In the processing of tobacco materials, processing equipment is required to control various physical properties of the materials (such as moisture content). To ensure that the material properties meet the requirements, processing parameters need to be adjusted based on factors such as the environment and the physical properties of different batches of materials. This process often requires referencing the test data of various physical properties of the materials from online instruments (such as moisture meters). Therefore, it is necessary to use laboratory testing methods and standard verification methods to regularly verify and correct the accuracy of online instruments.

[0003] Taking a tobacco sheet re-drying machine as an example, existing technology, to ensure the material's moisture content meets standards, includes online moisture meters and manual sampling windows on both sides of the middle of the equipment. Several sampling personnel periodically and simultaneously take quantitative vertical samples from above the main conveyor belt on both sides of the equipment within a specified time. After obtaining the samples, they are quickly placed in sample containers, sealed, labeled, and sent for testing. The moisture content of the samples is measured using the oven drying method, and the moisture meter readings are recorded several times and averaged. Finally, the moisture meter is calibrated and corrected using two sets of data according to prescribed methods.

[0004] In the specific manual sampling process, several sampling personnel need to climb ladders from both sides of the equipment, reach their hands into the equipment through the sampling window, grab materials from both sides of the running conveyor belt, and then remove the materials from the window and place them in a container for testing. This process carries a high risk to production safety, requiring careful operation to avoid touching the running tobacco re-drying machine conveyor belt and guard plates to prevent scratches. Furthermore, due to objective differences in the height, arm span, and reaction time of the sampling personnel, manual sampling involves random errors in point location, depth, and synchronization, leading to doubts about the accuracy and validity of the sample moisture content.

[0005] Meanwhile, in existing equipment, for sampling of tobacco sheet re-drying machines with a conveyor width of nearly 3.5m, to ensure the representativeness of the sample material, it is best to simultaneously sample three points (left, center, and right) on the same cross-section of the material in the process processing equipment. Existing manual sampling techniques are quite difficult to sample material in the middle of the same cross-section.

[0006] A search revealed another patent, CN220230984U, entitled "Automatic Sampling Device for Online Infrared Moisture Analyzer Calibration in Cigarette Production Process," which discloses an automatic sampling device for tobacco materials passing through the probe of an online infrared moisture analyzer. Driven by the online infrared moisture analyzer, the device is characterized by comprising: a material-gas conveying pipe (6), one end of which is provided with a material suction port (5) to absorb tobacco material samples; and a blower (9) connected to the other end of the material-gas conveying pipe (6). The output end of (9) is connected to the input end of the gas-material separator (7); a sample collection box (8) is provided at the output end of the gas-material separator (7), and the sample collection box (8) is sealed to the gas-material separator (7). The tobacco material sample falls into the sample collection box (8) after being separated by the gas-material separator (7); the control system is linked with the online infrared moisture meter, and the automatic sampling device is driven by the online infrared moisture meter through the control system to control the automatic sampling device to start or stop sampling. This patent also has the following technical problems:

[0007] On the one hand, the sample collection method of this technical solution is negative pressure suction. This method cannot solve the problem of collecting materials at a constant depth and quantity as required by this patent; negative pressure suction cannot collect materials at the same depth in each cross-section. For example, in the same cross-section of a process processing equipment, the materials have upper, middle and lower layers in the depth direction, and the moisture content is not the same. On the other hand, the above-mentioned device cannot ensure that the proportion of upper, middle and lower layers of materials is the same each time it is sampled. Negative pressure suction requires a large amount of airflow to transport the materials. This process changes the moisture content of the materials significantly, which reduces the accuracy and representativeness of the sample materials. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0073] In summary, a more specific embodiment of this utility model is as follows:

[0074] Before using the online sampling device for a process processing equipment with the above-mentioned design structure, it needs to be manufactured and installed as a backup.

[0075] As per the instruction manual Figures 1-18 As shown, an online sampling device for a process processing equipment includes a control system 7 connected to several online moisture meters 3 inside the processing equipment 9, and further includes:

[0076] Follow-up system 1 is connected to the left and right sides and the middle of the sampling point box 91 above by connecting frame 14. The sampling point box 91 is provided with a pick-up and put-out port adapted to each set of follow-up system 1.

[0077] Lifting system 2 is connected to each follower system 1 and is used to drive the material handling system 4 connected to it to move up and down.

[0078] Material handling system 4 is connected to the lower end of lifting system 2 and is used to grab materials and put them into the corresponding discharge system 5.

[0079] The discharge system 5 is located at one end of the corresponding follow-up system 1 and is used to collect materials.

[0080] Furthermore, it also includes a partition assembly 8, which is respectively installed at each sampling port on the sampling point box 91, for sealing and opening the sampling ports.

[0081] Specifically, the partition assembly 8 includes:

[0082] The movable cover plate 81 is slidably connected to the sampling point box 91 above the pick-up and drop-out port;

[0083] The cover plate drive component 82 is connected to the connecting frame 14 on one side. The working end of the cover plate drive component 82 is connected to the movable cover plate 81 and is used to drive the movable cover plate 81 to move and open or close the corresponding pick-up and put-out port.

[0084] In this utility model, the cover plate drive component 82 is a cylinder.

[0085] Furthermore, the follow-up system 1 is used to drive the lifting system 2 connected thereto to reciprocate along the conveying surface of the main conveyor belt 92;

[0086] The servo system 1 includes:

[0087] Linear module 11, which is connected to the connecting frame 14;

[0088] A drive motor 12 is connected to one end of the linear module 11 and provides power to the linear module 11.

[0089] Slider 13 is slidably connected to linear module 11;

[0090] The slider 13 is driven by the drive motor 12 and can move synchronously with the main conveyor belt 92. The drive motor 12 is connected to the control system 7.

[0091] Furthermore, the lifting system 2 includes:

[0092] Lifting module 21, the lower part of which is connected to slider 13;

[0093] The lifting drive motor 22 is connected to the top of the lifting module 21 and provides power to the lifting module 21.

[0094] The lifting slider 23 is slidably connected to the lifting module 21.

[0095] The lifting slider 23 reciprocates along a straight line perpendicular to the conveying surface of the main conveyor belt 92. The lifting drive motor 22 is controlled by the control system 7, which enables the lifting slider 23 to precisely control its relative distance to the main conveyor belt 92.

[0096] In this utility model, the linear module 11 and the lifting module 21 can be linear modules, Cartesian coordinate robots, linear slides, and the transmission method can be synchronous belt, lead screw, chain, gear rack or cylinder piston; the drive motor 12 and the lifting drive motor 22 can be servo motors, stepper motors, ordinary motors or compressed air.

[0097] Furthermore, the material handling system 4 includes:

[0098] The upper end of the gripper 41 is connected to the lifting slider 23 of the lifting system 2 via a connecting rod;

[0099] The gripper 42 is symmetrically connected to both ends of the gripper 41. The gripper 42 is connected to the corresponding fingers of the gripper 41, and the number of grippers 42 is the same as the number of fingers of the gripper 41. Driven by the fingers of the gripper 41, it can close or open at a certain angle.

[0100] Among them, the grab bucket 42 can grab the material above the main conveyor belt 92 at a fixed point and depth.

[0101] In this invention, the swing driver 31 can be a swing cylinder, which can be driven by compressed air, a servo motor, a stepper motor or a regular motor.

[0102] Furthermore, the discharge system 5 is connected to the outside of the corresponding follower system 1 via a support frame, and the discharge system 5 includes:

[0103] The material collection bin 51 is installed on the support frame and is located above the outlet end of the main conveyor belt 92;

[0104] The upper end of the sealing head 52 is connected to the lower end of the collection bin 51.

[0105] In this invention, the collection bin 51 can prevent material accumulation and sticking; the sealing head 52 is located outside the protective cover 53, which makes it convenient for sampling personnel to place the sampling container and prevent the sample from spilling or leaking.

[0106] Specifically, above the sampling point box 91 of each follow-up system 1 and discharge system 5, there is also a 53, in which the lower end of the sealing head 52 obliquely protrudes from the lower part of the protective cover 53.

[0107] In this invention, the control system 7 is located near the sampling point housing 9 of the processing equipment and consists of a programmable controller, a memory, a driver, a display, and an operation interface, among other control and communication devices. The control system 7 can receive feedback signals from the sensing device 6 and the online moisture meter 3, and store and display the detection data of the online moisture meter 3 based on the feedback signals, the sampling personnel's control signals, and preset program switches, thereby controlling the operation of the aforementioned systems.

[0108] In this invention, the control system is equipped with an integrated label printer. After sampling, the system automatically prints information such as material details, sampling location, sampling time, and average moisture content measured by the moisture meter onto self-adhesive stickers. These stickers are then affixed by the sampler to the corresponding sealed box / bag to prevent sample confusion during subsequent oven-drying testing. This facilitates sampler labeling and reduces workload.

[0109] When using:

[0110] Step 1, Sampling begins: The sampling personnel place the sampling container below the discharge system 5 and the operation control system 7 sends a start signal;

[0111] Step 2, data recording begins: The follow-up system 1 and the lifting system 2 operate. After the material handling system 4 reaches the sampling start position, the control system 7 begins to read and store the detection data of the online moisture meter 3 and the time displayed by the built-in clock of the control system 7 at set time intervals.

[0112] Step 3, Sample Grabbing: Simultaneously with the start of data recording, the follow-up system 1 and the lifting system 2 operate according to the speed and direction signals output by the control system 7, so that the material handling system 4 moves at the same speed and in the same direction as the main conveyor belt 92; at the same time, the gripper 41 of the material handling system 4 drives the grab bucket 42 to close, completing the sample grabbing action. The control system 7 outputs signals according to the interval time set by the program, controlling the operation of the follow-up system 1 and the lifting system 2, so that the material handling system 4 reaches the sampling completion position;

[0113] Step 4, data recording ends: The material handling system 4 reaches the sampling completion position, the control system 7 ends the reading and storage of the detection data of the online moisture meter 3 at the set time interval, and calculates and displays the average value of the detection data of the online moisture meter 3 during this sampling process, the sampling time, the batch of the processed material and other information according to the set program;

[0114] Step 5, Sampling ends: In parallel with the step of the control system 7 displaying the detection data of the online moisture meter 3, the follow-up system 1 and the lifting system 2 operate according to the speed and direction signals output by the control system 7, so that the material handling system 4 moves to the top of the collection bin 51 of the discharge system 5. The control system 7 controls the grab bucket 42 of the material handling system 4 to open, and the sample enters the collection bin 51 under the action of gravity and then falls into the sampling container at the sealing head 52 of the discharge system 5.

[0115] Step 6, Sample testing steps: The sampling personnel, according to the information displayed by the control system 7, seal the sampling container and mark and record the average value of the data detected by the online moisture analyzer 3, the sampling time, the batch of the processed material, and other information before sending it for testing. The moisture content standard value of the sample is measured by the oven drying method.

[0116] Step 7, Instrument Verification Steps: Relevant personnel determine the detection accuracy of the online moisture meter according to the average value of the detection data of the online moisture meter 3 and the standard value of sample moisture content using the prescribed method. Then, they determine whether the online moisture meter needs to be calibrated and the value of the calibration coefficient according to industry standards.

[0117] Between steps 1 and 2 above, since it is located in the partition assembly 8, the control system 7 needs to control the cover drive 82 to move the movable cover 81 to open the pick-up and put-out port, so as to facilitate the operation of the follow-up system 1, the lifting system 2 and the pick-up and put-out system 4.

[0118] Example 2

[0119] This embodiment is basically the same as embodiment 1, except that it also includes a sensing device 6 for detecting whether the moving parts in each system are in place. The sensing device 6 includes multiple sub-sensing devices, which are located at the designed positions of each system. They are composed of several proximity switches, limit switches, photoelectric switches and encoders. They are used to detect whether the moving parts in each system are in place, the real-time conveying speed of each drive and the main conveyor belt 92 of the processing equipment, and to feed the detection signal back to the control system 7. The control system 7 is located below one side of the processing equipment 9.

[0120] During use, since each system is equipped with a sensing device 6 for detecting whether each moving part is in position, after step 1, the system self-test can be started: the sensing device 6 detects whether the moving parts in each system are within the allowable range, and detects the belt speed of the main conveyor belt 92 to determine whether it is within the allowable range; if there is an abnormality, the sampling personnel will be prompted to suspend sampling and make corrections.

[0121] When used in step 2, the control system 7 can detect the corresponding signal of the sensing device 6, and start reading and storing the detection data of the online moisture meter 3 and the time displayed by the built-in clock of the control system 7 at set time intervals.

[0122] In step 2, during belt speed detection, the control system 7 reads the belt speed detection signal of the main conveyor belt 92 from the sensing device 6 to determine whether the belt speed of the main conveyor belt 92 is within the allowable range. If the belt speed exceeds the set range, a warning message is issued to prompt the sampling personnel to suspend sampling and correct the belt speed; if the belt speed is within the set range, the current running speed data of the main conveyor belt 92 is read and stored, and the process proceeds to the next step.

[0123] During the status detection and correction of each system, the control system 7 reads the position signals of each sub-sensing device corresponding to each system. If the requirements are met, a start signal is output to proceed to the next step; otherwise, a position correction command is issued to control the drive motor of each system to start in the programmed direction and run until the position signal of each subsystem is correct.

[0124] In step 5, after the control system 7 detects the signal corresponding to the sensing device 6, it can quickly display the sampling end information.

[0125] Preferred design: This scheme limits the total height of the sampling unit to 1.8m, reducing the overall height of the guardrail and equipment, thus lessening the torque load on the X-axis while providing a 2.1m vertical lifting stroke. Furthermore, the electric cylinder modules for the X and Z axes are always positioned above the outer edge of the sampling point housing 91, with the material discharge height of the sampling container approximately 1m above the top of the sampling point housing 91. This prevents accidental grease leakage and contamination of materials, avoids the impact of high temperatures, humidity, and dust on sensitive components, and facilitates maintenance and material collection.

[0126] Each sampling port is equipped with a partition assembly 8, and a cylinder-driven movable cover 81 is installed above the sampling point box 91. The movable cover 81 is normally closed and only opened during sampling. Combined with the flange design at the top of the sampling port, it can prevent foreign objects from falling into the sampling point box 91 and contaminating the material, and can also prevent dust and moisture inside the sampling point box 91 from affecting the sampling system.

[0127] The sampling system works as follows: the sampler issues a sampling command, the system self-checks whether each device is in the correct position, the control system reads the conveyor belt speed and judges whether the speed is appropriate; if all parameters are normal, the belt speed data is stored and the movable cover 81 is opened; the follow-up system 1 moves to the correct position, the material handling system 4 unfolds to the correct position and then pauses, and the pneumatic gripper assembly is in the sampling start position; sampling begins, the follow-up system 1 runs at the designed distance according to the main conveyor belt speed 92 and then pauses, the lifting system 2 is delayed for several seconds and then raised to the folded position and pauses, during which time the pneumatic gripper assembly closes to the correct position; the follow-up system 1 runs to the sampling position and stops, the movable cover 81 closes, and the material handling system 4 opens to complete the sampling.

[0128] In the above embodiments, the acquisition of sample moisture data involved in this invention is carried out in accordance with relevant industry regulations. For example, the "Cigarette Processing Specification," section 13.2.4.2, specifies:

[0129] While the material is passing through normally, take samples and measure their moisture content using the oven drying method, recording the moisture meter readings at least five times during sampling. The calculation formula is as follows:

[0130]

[0131] In the formula:

[0132] —Detection accuracy %;

[0133] —Measured moisture content of material in the i-th time, %, where i is a natural number from 1 to n;

[0134] —Displays the moisture content % of the material in the i-th iteration, where i is a natural number from 1 to n.

[0135] —Number of tests.

[0136] The above-mentioned oven drying method 13.1.4.1.2 stipulates:

[0137] a sampling method

[0138] Sampling should be done during the stable production phase, taking approximately 50-100g of samples randomly within 3.0m of the inlet or outlet of each process equipment or within 20cm of the moisture meter detection point, and placing them in a sealed sample box or bag.

[0139] b Sample preparation

[0140] After the samples are mixed thoroughly, take a certain amount of sample and place it in a sample box of known weight. Immediately close the box and weigh it to an accuracy of 0.001g. Each sample should be measured at least twice in parallel.

[0141] c Sample Detection

[0142] When the oven temperature stabilizes at 100±1℃, open the lid of the sample box and place it at the bottom of the box in the middle rack of the oven. The sample boxes should be placed at a density of no less than 1 box per 120cm². 2 Close the oven door and start timing. After 2 hours, open the oven door, cover each sample box, remove them, and place them in a desiccator. After cooling to room temperature, weigh each sample to an accuracy of 0.001g and calculate the sample moisture content using the following formula:

[0143]

[0144] In the formula:

[0145] W — Sample moisture content;

[0146] m1 — Weight of the sample before drying (g);

[0147] m2——Weight of the sample after drying (g).

[0148] Calculate the average moisture content of the parallel samples.

[0149] Additional Example: After the sampler issues a sampling command, the control system begins to read and store the online moisture meter measurement data. The storage frequency is no less than 5 times, and the storage duration is determined by the conveying speed of the process equipment and the coverage area of ​​the sampling container. In principle, the material corresponding to the recorded data and the sample material are within the same cross-sectional area.

[0150] Further optimizations include integrating a label printer to facilitate samplers in marking sample information and reducing workload. After sampling, the control system automatically prints material information, sampling location, sampling time, and average moisture content on self-adhesive stickers, which samplers can then affix to the corresponding sealed box / bag to prevent sample confusion during subsequent oven-drying testing.
