Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, and in particular to a box strip traceability code association device and method. Background Technology

[0002] In modern consumer goods industries, particularly food, pharmaceuticals, tobacco, and cosmetics, ensuring product quality and safety, combating counterfeiting, and achieving refined supply chain management typically requires printing unique digital identification codes (i.e., traceability codes) on product packaging. A complete traceability system usually requires printing independent traceability codes (called "package codes" and "barcodes") on the smallest sales unit (small package) and on a carton consisting of multiple small packages, and linking the two through a data management system. Thus, during distribution, scanning the barcode provides information on all the small packages within it, while scanning any package code allows tracing back to its original barcode and batch, achieving forward tracking and reverse traceability throughout the entire supply chain.

[0003] In the existing technology, a typical existing production process is as follows: First, on an independent small package packaging line, a unique package traceability code is printed online for each small package; then, these coded small packages are automatically collected and arranged according to a predetermined quantity (such as ten boxes per pack), and the pack packaging machine completes the pack box forming and sealing, and prints a unique bar traceability code for each pack during this process; finally, through a central control system, the codes of small packages in the same batch are logically associated with the corresponding barcodes and stored in the database.

[0004] However, the online coding process for small packages is susceptible to interference from factors such as material characteristics, high-speed vibrations on the production line, printhead clogging, or unstable ink (or laser) conditions, leading to incomplete, blurry, unreadable, or completely missing coding. These uncoded or defective packages flow into subsequent baggage packaging processes, creating an "information black hole"—baggage contains untraceable packages. This not only undermines the integrity of the traceability system, breaking the traceability chain for that baggage and even the entire batch of products, but more seriously, products containing untraceable units enter the market. If quality issues arise, recalls become difficult, responsibility cannot be determined, and significant compliance risks and brand reputation damage occur for the company.

[0005] Therefore, there is an urgent need for a box tag traceability code association device and method that can reduce the outflow rate of products with incomplete traceability codes. Summary of the Invention

[0006] The purpose of this invention is to provide a box and bar traceability code association device and method to solve the problems existing in the prior art. By using a third barcode reader and a second barcode reader located downstream of the rejection mechanism, the invalid package traceability code is rejected while associating the complete package traceability code and the bar traceability code.

[0007] To achieve the above objectives, the present invention provides the following solution: This invention provides a box tag traceability code association device, comprising: Computer, conveying mechanism, and the following arranged sequentially along the conveying direction of the conveying mechanism: A first coding machine, the working end of the first coding machine is arranged facing the conveying mechanism, and the first coding machine is capable of printing a package traceability code for small packages; A first barcode reader, the working end of the first barcode reader being positioned facing the conveying mechanism; The rejection mechanism is connected to the first code reader and is capable of rejecting small packages whose traceability codes cannot be identified. A second barcode reader, the working end of which is positioned facing the conveying mechanism; A second coding machine, the working end of which is positioned facing the conveying mechanism, is capable of printing bar traceability codes on the packaging paper of the bar pack; A third barcode reader, the working end of which is positioned facing the conveying mechanism; The second and third barcode readers are connected to the computer via signals, and the computer is able to associate the information read by the second and third barcode readers.

[0008] In one embodiment, the conveying mechanism includes a first conveyor belt and two clamping belts with the same conveying direction. The first conveyor belt is horizontally arranged, and the two clamping belts are vertically arranged above the first conveyor belt. There is a clamping space between the two clamping belts that can clamp the small package. The two clamping belts move at the same speed and can drive the small package to move along the conveying direction of the first conveyor belt. The working end of the first coding machine faces the clamping space.

[0009] As one embodiment, it also includes a drive motor, and the drive shafts of both clamping belts are connected to the output shaft of the drive motor.

[0010] In one embodiment, the conveying mechanism includes a second conveyor belt, a conveying track, and a pushing mechanism. The second conveyor belt is connected to the first conveyor belt. The conveying direction of the conveying track is perpendicular to the conveying direction of the second conveyor belt. The entrance end of the conveying track is located on one side of the second conveyor belt. The pushing mechanism is located on the side of the second conveyor belt away from the conveying track. The pushing mechanism is correspondingly arranged with the conveying track. The pushing direction of the pushing mechanism is parallel to the conveying direction of the conveying track. The working end of the second barcode reader is correspondingly arranged with the entrance end of the conveying track. The second barcode reader is signal-connected to the pushing mechanism.

[0011] As one embodiment, the conveying mechanism further includes a third conveyor belt, which is arranged parallel to the upper side of the second conveyor belt, and the gap between the second conveyor belt and the third conveyor belt is not greater than the dimension in the width direction of the small package.

[0012] In one embodiment, the second barcode reader includes a main barcode reader and a secondary barcode reader, with the main barcode reader located upstream of the secondary barcode reader and the main barcode reader and the secondary barcode reader being signal-connected.

[0013] As one embodiment, it also includes a baffle plate, which is disposed at the entrance end of the conveying track along the conveying direction of the second conveyor belt, and the baffle plate is disposed on the side of the conveying track away from the first conveyor belt.

[0014] As one embodiment, it also includes an encoder, which is signal-connected to the pushing mechanism, the second barcode reader, and the second coding machine, respectively. The encoder can control the working state of the second barcode reader and the second coding machine according to the working state of the pushing mechanism.

[0015] In one embodiment, the first coding machine is signal-connected to the computer, and the computer can obtain the loss amount based on the information from the first coding machine and the information from the second code reader.

[0016] This invention provides a method for associating box tag traceability codes, using the aforementioned box tag traceability code association device, and includes the following steps: Step S1: The first coding machine prints a traceability code for the small packages on the conveyor mechanism; Step S2: The first reader performs a code reading operation on the small packet; Step S3: The rejection mechanism rejects small packages whose traceability codes cannot be identified. Step S4: The second barcode reader performs a barcode reading operation on the small packet; Step S5: The second coding machine prints a barcode traceability code on the packaging paper of the bar package; Step S6: The third barcode reader performs a barcode reading operation on the barcode package; In step S7, the computer associates the information read by the second barcode reader with the information read by the third barcode reader.

[0017] The present invention achieves the following technical effects compared to the prior art: In the box bar traceability code association device and method disclosed in this invention, a first coding machine can print a package traceability code for a small package. A first barcode reader located downstream of the first coding machine can read the package traceability code on the small package. If the first barcode reader fails to read the code, it indicates that the package traceability code on the corresponding small package is unqualified. At this time, the first barcode reader sends a signal to the rejection mechanism, and the rejection mechanism works to reject the small package with the unqualified package traceability code from the conveying mechanism, strictly ensuring that the small package with the unqualified package traceability code will not flow downstream. If the first barcode reader reads the code successfully, it indicates that the package traceability code on the corresponding small package is qualified, the rejection mechanism does not work, and the corresponding small package enters the downstream. A second barcode reader can identify the package traceability code on the incoming small package, and a third barcode reader can identify the bar traceability code on the packaging paper of the bar package. The computer can associate the complete package traceability code read by the second barcode reader with the bar traceability code read by the third barcode reader, achieving the technical effect of reducing the outflow rate of products with incomplete traceability codes.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The purpose of this invention is to provide a box and bar traceability code association device and method to solve the problems existing in the prior art. By using a third barcode reader and a second barcode reader located downstream of the rejection mechanism, the outflow rate of products with incomplete traceability codes can be reduced while associating complete package traceability codes and bar traceability codes.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 Please refer to Figure 1 - Figure 3This embodiment provides a box tag traceability code association device, including: a computer, a conveying mechanism, and a first coding machine 1, a first code reader 3, a rejection mechanism 4, a second code reader, a second coding machine 5, and a third code reader 6 arranged sequentially along the conveying direction of the conveying mechanism; wherein, the working end of the first coding machine 1 is set facing the conveying mechanism, and the first coding machine 1 can print a package traceability code for the small package 2 (i.e., the box); the working end of the first code reader 3 is set facing the conveying mechanism; the rejection mechanism 4 is signal-connected to the first code reader 3, and the rejection mechanism 4 can reject the small package 2 that cannot be identified by the package traceability code; the second coding machine 5, the third code reader 6, the fourth code reader 6, the fifth code reader 7, the sixth code reader 8, the seventh code reader 9, the 10th code reader 1, the 11th code reader 1, the 12th code reader 1, the 13th code reader 1, the 14th code reader 1, the 15th code reader 1, the 16th code reader 1, the 17th code reader 1, the 18th code reader 1, the 19 ... The working ends of the second barcode reader 5 and the second barcode printer 5 are positioned facing the conveying mechanism. The second barcode printer 5 can print barcode traceability codes on the packaging paper of the package. The working end of the third barcode reader 6 is positioned facing the conveying mechanism. The second and third barcode readers 6 are connected to a computer signal. The working principle is as follows: the conveying mechanism can transport the small package 2 placed upstream to downstream. When the small package 2 reaches the corresponding position of the first barcode printer 1, the first barcode printer 1 can print a package traceability code on the small package 2. The first barcode reader 3 can detect the traceability code on the small package 2. If the first barcode reader... If the first barcode reader 3 can recognize the traceability code on the small package 2, it means the traceability code is qualified, and the downstream rejection mechanism 4 does not operate. If the first barcode reader 3 cannot recognize the traceability code on the small package 2, it means the traceability code is unqualified. At this time, the first barcode reader 3 sends a signal to the rejection mechanism 4, and the rejection mechanism 4 operates, removing the small package 2 corresponding to the unqualified traceability code from the production line, thus preventing the small package 2 with the unqualified traceability code from flowing downstream. The small package 2 with the qualified traceability code continues to move downstream under the action of the conveyor mechanism. When it moves to the second barcode reader, the second barcode reader can... The system identifies the package traceability code on small package 2 and transmits the information of the package traceability code to the computer. The second coding machine 5 can print a bar traceability code on the packaging paper of the bar package. The third barcode reader 6 can identify the bar traceability code on the packaging paper of the bar package and transmit the information of the bar traceability code to the computer. The computer can associate the package traceability code on small package 2 with the bar traceability code on the packaging paper of the bar package. By adopting the above method, invalid package traceability codes can be removed while associating package traceability codes and bar traceability codes, thus preventing products with unqualified traceability codes from leaving the market and achieving the technical effect of reducing the outflow rate of products with incomplete traceability codes.

[0025] In one embodiment, the conveying mechanism includes a first conveyor belt 7 and two clamping belts 8 with the same conveying direction. The first conveyor belt 7 is horizontally arranged, and the two clamping belts 8 are both vertically arranged above the first conveyor belt 7. There is a clamping space between the two clamping belts 8 that can clamp the small package 2. The two clamping belts 8 move at the same speed and can drive the small package 2 to move along the conveying direction of the first conveyor belt 7. The working end of the first coding machine 1 faces the clamping space. After the small package 2 is placed on the first conveyor belt 7, the first conveyor belt 7 can drive the small package 2 to move downstream. The conveying direction of the two conveyor belts is the same as that of the first conveyor belt 7. When the small package 2 moves to the corresponding position of the clamping belt 8, it will enter the clamping space between the two clamping belts 8. Since the gap between the two clamping belts 8 is smaller than the size of the small package 2, the two clamping belts 8 can clamp the small package 2. The clamping force of the two clamping belts 8 on the small package 2 is greater than the friction between the small package 2 and the first conveyor belt 7. At this time, the small package 2 will move at the same speed as the two clamping belts 8. Under the action of the clamping belts 8, the small package 2 passes through the working end of the first coding machine 1. The running speed of the two clamping belts 8 and the working rhythm of the coding machine are dynamically coordinated and stably synchronized, ensuring that the coding machine is in the best printing state when each small package 2 passes through the coding area, thereby improving the pass rate of the package traceability code.

[0026] In one embodiment, the package traceability code is printed at one end of the length direction of the small package 2, and the width direction of the small package 2 is set along the conveying direction of the first conveyor belt 7, that is, the distance between the two clamping belts 8 is less than the thickness of the small package 2.

[0027] In one embodiment, the conveying mechanism further includes a drive motor 9, and the drive shafts of both clamping belts 8 are connected to the output shaft of the drive motor 9. This one-drive-multiple-drive approach reduces the complexity of the device. It is understood that the drive shafts of the two clamping belts 8 are arranged in parallel. To ensure that the conveying directions of the two clamping belts 8 are the same, the rotation directions of the drive shafts of the two clamping belts 8 are opposite. Therefore, one drive shaft can be directly connected to the drive motor 9, and the other drive shaft can be connected to the drive motor 9 through a reversing gear set. Alternatively, one drive shaft can be directly connected to the drive motor 9, and the other drive shaft can be connected to the first drive shaft through a reversing gear set.

[0028] In one embodiment, the conveying mechanism includes a second conveyor belt 10, a conveying track 11, and a pushing mechanism 12. The second conveyor belt 10 is connected to the first conveyor belt 7. The conveying direction of the conveying track 11 is perpendicular to the conveying direction of the second conveyor belt 10. The entrance end of the conveying track 11 is located on one side of the second conveyor belt 10. The pushing mechanism 12 is located on the side of the second conveyor belt 10 away from the conveying track 11. The pushing mechanism 12 is correspondingly arranged with the conveying track 11. The pushing direction of the pushing mechanism 12 is parallel to the conveying direction of the conveying track 11. The working end of the second barcode reader is correspondingly arranged with the entrance end of the conveying track 11. The second barcode reader is signal-connected to the pushing mechanism 12. The second conveyor belt 10 is perpendicular to the conveyor track 11. When the small package 2 reaches the position corresponding to the conveyor belt and the conveyor track 11, the small package 2 needs to rely on the pushing mechanism 12 to enter the conveyor track 11. The second barcode reader can read the package traceability code on the small package 2 and record the number of package traceability codes read. The pushing mechanism 12 pauses for a certain period of time after each pushing action, and the working rhythm of the pushing mechanism 12 matches the working rhythm of the second conveyor belt 10. During the pause time of the pushing mechanism 12, the second conveyor belt 10 can transport a specified number of small packages 2 to the area corresponding to the entrance end of the conveyor track 11. Then the pushing mechanism 12 moves to push multiple small packages 2 corresponding to the area corresponding to the entrance end of the conveyor track 11 into the conveyor track 11 together, realizing the single transport of a specified number of small packages 2. During the process of the small package 2 entering the area corresponding to the entrance end of the conveyor track 11, the second barcode reader is always in working state to read the package traceability code on the small package 2.

[0029] Understandably, the second barcode reader has a built-in algorithm that can record the number of complete traceability codes read by the second barcode reader.

[0030] In one embodiment, the pushing mechanism 12 is an existing structure with a pushing function, such as a linkage mechanism driven by a motor, a push rod, or a cylinder. Taking a push rod as an example, a push plate is installed at the working end of the push rod to push multiple small packages 2 at the same time.

[0031] In one embodiment, the working rhythm of the pushing mechanism 12 and the second conveyor belt 10 is adjustable; preferably, during the time the pushing mechanism 12 is idle, the second conveyor belt 10 can transport ten small packages 2 to the area corresponding to the entrance end of the conveyor track 11.

[0032] In one embodiment, taking the pushing mechanism 12 as a linkage mechanism driven by a motor as an example, the control rhythm of the pushing mechanism 12 can be adjusted by controlling the speed of the motor.

[0033] In one embodiment, the second conveyor belt 10 is driven by a motor, and the working rhythm of the second conveyor belt 10 can be adjusted by adjusting the output power of the drive motor of the second conveyor belt 10.

[0034] In one embodiment, the working end of the second coding machine 5 is positioned facing the conveyor track 11, that is, the packaging paper of the bar pack is printed with bar traceability codes on the conveyor track 11.

[0035] In one embodiment, after a specified number of small packages 2 enter the conveyor track 11, the specified number of small packages 2 can move downstream together with the packaging paper of the strip package and enter the strip packaging machine to complete the packaging of the strip package.

[0036] In one embodiment, the box tag traceability code association device further includes a packaging paper feeding mechanism, which can transport the packaging paper of the package to a designated position on the conveying track 11.

[0037] In one embodiment, the second coding machine 5 can print the bar traceability code when the packaging paper is placed on the conveyor track 11, or it can print the bar traceability code while the packaging paper and the small package 2 are moving downstream together.

[0038] In one embodiment, the conveying mechanism further includes a third conveyor belt 13, which is arranged parallel to the upper side of the second conveyor belt 10. The gap between the second conveyor belt 10 and the third conveyor belt 13 is no greater than the width dimension of the small package 2. This arrangement ensures the stability of the small package 2 during conveying. It is understood that structures capable of adjusting the orientation of the small package 2, such as robotic arms or adjusting blocks, are provided upstream of the second and third belts to change the orientation of the small package 2 from a vertically extending form along its length to a vertically extending form along its width.

[0039] In one embodiment, the second barcode reader includes a main barcode reader and a secondary barcode reader. The main barcode reader is located upstream of the secondary barcode reader, and the main and secondary barcode readers are signal-connected. The main and secondary barcode readers use burst mode dynamic barcode reading. One end of the printed traceability code on the small package 2 faces the main and secondary barcode readers. The main and secondary barcode readers can quickly take pictures of the small package 2, thus capturing multiple photos with the traceability code. Among these photos, there will inevitably be duplicate traceability codes and incomplete traceability codes. The system built into the main barcode reader can automatically ignore duplicate and incomplete traceability codes until a specified number of non-duplicate traceability codes are parsed from the photos taken by the main and secondary barcode readers. By using two barcode readers in cooperation, the reading speed of the traceability code is improved while ensuring complete reading, thereby ensuring the working efficiency of the device.

[0040] In one embodiment, the main barcode reader is connected to a computer and is used to transmit the information read by the main barcode reader and the secondary barcode reader to the system.

[0041] In one embodiment, the box tag traceability code association device further includes a baffle plate 14, which is disposed at the entrance end of the conveyor track 11. Along the conveying direction of the second conveyor belt 10, the baffle plate 14 is disposed on the side of the conveyor track 11 away from the first conveyor belt 7. The baffle plate 14 can prevent the first counted small package 2 from moving to the downstream side of the entrance end of the conveyor track 11 before the second code reader reads the specified number of package traceability codes, thus ensuring that the specified number of small packages 2 can enter the conveyor track 11 together.

[0042] In one embodiment, the box tag traceability code association device further includes an encoder 15, which is connected to the push mechanism 12, the second code reader, and the second coding machine 5. The encoder 15 can control the working state of the second code reader and the second coding machine 5 according to the working state of the push mechanism 12. Encoder 15 is connected to push mechanism 12. When push mechanism 12 completes its forward push, encoder 15 detects a +V signal. At this time, small package 2 enters conveyor track 11. Encoder 15 sends a signal to the second coding machine 5 to start coding. Small package 2 entering conveyor track 11 will be able to move downstream along with the packaging paper of the strip package. Furthermore, subsequent small packages 2 on the second conveyor belt cannot continue to move downstream. That is, along the conveying direction of the second conveyor belt, small package 2 is intercepted on the upstream side of the entrance end of conveyor track 11. Encoder 15 sends a signal to the second code reader to end the acquisition. The second code reader stops acquiring the package traceability code of small package 2. When push mechanism 12 completes its retraction action, encoder 15 detects a -V signal. Encoder 15 sends a signal to the second coding machine 5 to stop coding. At this time, small package 2 on the second conveyor belt can continue to move towards the corresponding position at the entrance end of conveyor track 11. Encoder 15 sends a signal to the second code reader to start the acquisition. The second code reader continues to acquire the package traceability code of small package 2.

[0043] In one embodiment, a baffle is provided on the side of the pushing mechanism 12 upstream of the second conveyor belt. When the pushing mechanism 12 extends, the baffle can prevent the small package 2 upstream of the second conveyor belt from continuing to move towards the corresponding position at the entrance end of the conveyor track 11. Alternatively, a telescopic plate can be provided on the side of the conveyor track 11 near the upstream of the second conveyor belt. The telescopic plate is horizontally positioned and perpendicular to the conveying direction of the second conveyor belt. When the pushing mechanism 12 extends, the telescopic plate also extends to block the small package 2 on the upstream side of the second conveyor belt.

[0044] In one embodiment, the first coding machine 1 is connected to a computer signal. The computer can obtain the loss amount based on the information from the first coding machine 1 and the information from the second code reader. Specifically, the first coding machine 1 can record the number of traceability codes it prints and upload it to the computer. The computer calculates the number of small packages 2 rejected by the rejection mechanism 4 by subtracting the number of traceability codes uploaded by the second code reader from the number of traceability codes uploaded by the first coding machine 1. The total number of rejected small packages 2 is the loss amount.

[0045] In one embodiment, the box label traceability code association device further includes a packaging machine, which is correspondingly arranged with the conveying mechanism. The packaging machine is located downstream of the second barcode reader and can package at least two small packages 2 into a package. Specifically, the number of small packages 2 in each package can be pre-adjusted according to actual needs. When any small package 2 passes the corresponding position of the second barcode reader, the second barcode reader can identify the package traceability code on the small package 2 and upload the package traceability code information to the computer. Subsequently, the small package 2 arrives at the conveying track 11, which can transport the small package 2 and the packaging paper of the package together to the packaging station of the packaging machine, thereby enabling multiple small packages 2 to be packaged into a package. The packaging machine is an existing structure, and its packaging principle will not be described in detail here.

[0046] In one embodiment, the third barcode reader 6 is connected to the bar packaging machine via a signal. The bar packaging machine is equipped with a bar packaging rejector. If the third barcode reader 6 cannot recognize the bar traceability code on the bar package, it means that the traceability code is unqualified. At this time, the third barcode reader 6 sends a rejection signal to the PLC of the bar packaging machine, and the bar packaging rejector is activated, removing the bar package corresponding to the unqualified traceability code from the production line, further reducing the risk of products with unqualified traceability codes flowing out. If the third barcode reader 6 can recognize the bar traceability code on the bar package, it means that the traceability code is qualified, and the bar packaging rejector does not activate.

[0047] Of course, the strip pack rejector can also be set on the subsequent conveying device. The conveying device is connected to the output end of the strip pack machine. By setting an independent detection and rejection device on the conveying device, strip packs with unqualified traceability codes can also be removed.

[0048] In one embodiment, after the third barcode reader 6 uploads the identified barcode information to the association system, the upper-level association system can verify its association data. If the association fails, it can also send a signal to the PLC of the barcode machine to remove the corresponding barcode.

[0049] In one embodiment, both the first coding machine 1 and the second coding machine 5 are laser coding machines. Of course, they can also be thermal inkjet printers, high-resolution inkjet printers, or UV inkjet printers.

[0050] In one embodiment, both the rejection mechanism 4 and the strip rejector are rejection nozzles connected to a high-pressure air source, with the outlet of the rejection nozzle coinciding with the movement path of the material. Alternatively, it can be a push rod-type rejection mechanism that can directly provide thrust.

[0051] In one embodiment, a motion state detection photoelectric sensor 16 is provided upstream of the first coding machine 1. The motion state detection photoelectric sensor 16 can detect the motion state of the small package 2 on the conveying mechanism.

[0052] In one embodiment, the first coding machine 1 is provided with a coding trigger photoelectric sensor 17. The detection path of the coding trigger photoelectric sensor 17 coincides with the movement path of the small package 2. When the small package 2 triggers the coding trigger photoelectric sensor 17, the first coding machine 1 works and starts coding the small package 2.

[0053] In one embodiment, the encoder 15 monitors the movement of the pushing mechanism 12. The encoder 15 has a built-in PLC or a computer has a built-in PLC to calculate the movement speed of the pushing mechanism 12 and determine when to send a signal, so as to compress the work cycle and improve production efficiency.

[0054] Example 2 This embodiment provides a method for associating box tag traceability codes, including the box tag traceability code association device described above, and includes the following steps: Step S1: The first coding machine 1 prints a package traceability code for the small package 2 on the conveying mechanism; Step S2: The first code reader 3 performs a code reading operation on the small packet 2; Step S3: The rejection mechanism 4 rejects the small package 2 whose traceability code cannot be identified; Step S4: The second code reader performs a code reading operation on small packet 2; Step S5: The second coding machine 5 prints a barcode traceability code on the packaging paper of the bar package; Step S6: The third barcode reader 6 performs a barcode reading operation on the barcode packet; In step S7, the computer associates the information read by the second barcode reader with the information read by the third barcode reader 6. This method can associate package traceability codes and barcode traceability codes while simultaneously removing invalid package traceability codes, preventing products with non-compliant traceability codes from leaving the market and achieving the technical effect of reducing the outflow rate of products with incomplete traceability codes.

[0055] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
