Abstract
Description
Technical Field
[0001] The invention relates to a livestock carcass coding method and a corresponding system, which are mainly used for marking meat. Background Art
[0002] Figure 1 This diagram illustrates an automated coding scenario in a slaughterhouse. Pork carcass halves 31, 32, 33, and 34 are hung on track 1 via hooks and move forward along the track at a speed of 0.1 to 0.2 m / s. Automated coding equipment 2 obtains each pig's coding information, quarantine information, and quality inspection information from the slaughterhouse's traceability information management platform and prints the corresponding pattern on the pigskin surface.
[0003] Figure 2 The printed pattern includes QR code, digital code, quality inspection seal, animal quarantine inspection seal, and other auxiliary information, such as serial number, slaughter line code, etc.
[0004] However, the automatic inkjet printer 2 cannot adapt well to the working environment of the slaughterhouse, cannot complete the automatic inkjet printing smoothly, and cannot guarantee the printing quality. The following are the problems often encountered in the slaughterhouse scene.
[0005] First of all, there are many breeds of live pigs in China, and they vary in length, fatness, weight, etc. Automated inkjet coding equipment cannot adapt to the coding of all types of live pig carcasses, or the cost of adapting to all types is relatively high.
[0006] Secondly, the slaughtering process for live pigs can vary greatly. Some pigs need to be split in half, while others do not, such as the carcasses for roasted pigs; some pig carcasses need to be headed, while others need to keep the head; some heads need to be kept intact, while others need to be split, etc. These different process flows also affect the operation of automated inkjet printers.
[0007] Furthermore, the coding of live pig carcasses is generally done near the spine, but when the pig carcasses are hung on the production line, the abdomen sometimes faces the coding equipment, affecting the operation of the automated coding equipment.
[0008] In addition, the slaughtering line cannot always maintain full production capacity. Some hooks are hung with pig carcasses, while some are empty. If the pig carcasses on the hooks cannot be effectively distinguished, it will affect the operation of the automatic coding equipment.
[0009] In addition, the business models of slaughterhouses include self-operation, slaughtering on behalf of others, or a mixture of the two. Different meat business entities have different requirements for the content of the coding, especially some brand customers, who need to print their own brand logos. In this way, different carcasses on the slaughtering line need to be accurately printed with different content.
[0010] In addition, in order to promote "high quality and high price", the meat industry needs to label and distinguish "high quality and high price" meat products, and also needs to print different labels when slaughtering.
[0011] As mentioned above, how to maintain the normal operation of the automated inkjet coding equipment, how to maintain the correct coding information printed on each pig carcass, and how to maintain the correct content of the inkjet printing on each pig carcass have become problems that must be solved. Summary of the Invention

DETAILED DESCRIPTION
[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0026] Figure 3 It is a schematic diagram of the application scenario of the present invention. The two parts 31, 32, 33, 34 and 35 of the pig carcass are hung on the track 1 by hooks and move forward along the track at a speed of 0.1~0.2 meters per second. The automatic coding equipment 2 obtains the coding information of each pig from the coding server of the slaughterhouse and prints the corresponding pattern on the surface of the pig skin. At the same time, camera 1 8 and camera 2 6 are also set at the coding site. Camera 1 8 identifies and counts the status of the pig carcasses entering the coding area. Camera 2 6 is used to identify the status of the pig carcasses after coding, including whether coding is performed, the quality of coding, and further, to identify and record the coding data. Due to the existence of the situation that is not suitable for coding as described in the background technology, a manual coding station is also provided on the slaughter line, and a handheld coding device 7 is used to re-print the pig carcasses that have not been coded.
[0027] Figure 4 The main controller obtains the coding information from the coding server and sends it to the first coding device and the second coding device. The first coding device and the second coding device cooperate to complete the pig carcass coding task of the slaughtering production line. Figure 3 , the first inkjet coding device is an automatic inkjet coding device 2, and the second inkjet coding device is a handheld inkjet coding device 7. The inkjet coding server communicates with the slaughter production management server to obtain slaughter production plan information and actual production information for completing the inkjet coding task. The main controller also interacts with the PLC controller to obtain the status information and detection data of the PLC controller, including the detection data signals of detection device 1 and detection device 2, and the pulse signal of the slaughter line motion encoder, and at the same time obtains the real-time status information of the automatic inkjet coding device 2, such as the start of the inkjet coding stroke, the end of the inkjet coding stroke, the moving speed, the length of the inkjet coding stroke, etc. The main controller sends the obtained information to the first inkjet coding device and the second inkjet coding device for controlling the inkjet coding. In addition, the inkjet coding server is also connected to camera 1 and camera 2, which correspond to Figure 3 Camera one 8 and camera two 6 are shown.
[0028] Figure 5The following diagram shows a detection scheme for fully automatic pig coding. The pig carcass halves 3 are hung on track 1 via hooks 5 and move forward along the track at a speed of 0.1 to 0.2 m / s. Hooks 5 are connected to rollers that roll along track 1, driving hooks 5 forward. On either side of hook 5 are installed detection devices 1: an infrared switch sensor transmitter 50 and an infrared switch sensor receiver 51. These devices are used for hook detection. When hook 5 passes by the infrared sensor, it blocks the infrared light emitted by the infrared switch sensor transmitter 50, preventing the infrared switch sensor receiver 51 from receiving the light. This signals the presence of a pig carcass and initiates the fully automatic coding process. However, if no pig carcass is hung on the hook, a misjudgment may occur, leading to the erroneous initiation of the fully automatic coding process.
[0029] A second detection device is installed in the head area of the lower pig carcass, which includes an infrared matrix grating sensor transmitting end 40 and an infrared matrix grating sensor receiving end 41. The length of the pig carcass is judged by detecting the blocked area of the infrared light 42, thereby determining the combination of the coding pattern or the length of the coding pattern, determining the marking stroke or marking area of the automatic coding equipment 2, and determining the clamping position of the pig carcass to prevent the pig carcass clamping component of the automatic coding equipment from clamping the correct part.
[0030] Along the forward direction of the production line, detection device 2 is installed in the front and detection device 1 is installed in the back. In this way, detection device 2 can first determine the pig carcass and the length of the pig carcass, that is, it determines that there is a pig hanging on the hook 5. In this way, when detection device 1 detects the presence of a hook, it can determine that there is a pig carcass hanging on the hook 5, so that the automatic inkjet printer 2 will not run empty, and the first inkjet printer automatic inkjet printer 2 will not have the situation of misprinting. Misprinting not only wastes ink, but more importantly, the traceability code that is misprinted will cause information confusion and statistical data problems, affecting the subsequent delivery of pork products and the corresponding paperless meat quality inspection certificate and animal product quarantine inspection certificate. The installation position distance between detection device 2 and detection device 1 can be consistent with the spacing between the hooks on the production line. Generally, it takes 6 seconds of running time, which is enough to complete the detection and information exchange.
[0031] Figure 6 This is the inkjet printing process flow chart of the present invention. In order to illustrate the possible problems in the inkjet printing process, the following Figure 6For explanation. Detection device 1 sequentially detects that hook A, hook B, hook C, hook D, hook E, and hook F have passed by. Detection device 2 sequentially detects that carcasses A, carcass B, carcass C, and carcass D have passed by and are hung on hooks B, hook C, hook E, and hook F, respectively. Hooks A and D do not have pig carcasses hung on them. There are many reasons for this, such as worker negligence, being too busy, or the pig carcass falling off during movement. However, carcass B is not suitable for automatic coding. The operator then controls the automatic coding device to pause coding, or the main controller controls the pause, and the handheld coding device 7 behind it performs manual coding. In this way, the main controller controls the automatic coding device 2 to execute the coding operations: coding A, coding B, and coding C. The corresponding traceability code sequences are traceability code A, traceability code C, and traceability code D, and the traceability code of the handheld coding device 7 is traceability code B. In this way, the carcass sequence and the traceability code sequence are one-to-one corresponding, avoiding information confusion caused by coding.
[0032] As mentioned above, in order to avoid misprinting of the traceability code and ensure that the pig carcass, traceability code, meat quality inspection certificate, and animal product quarantine inspection certificate are consistent, the coding process must be done in sequence for each pig carcass. To ensure the accuracy of the information, the following information is recorded for each test result of the detection device 2: 1) Detection count 2: the cumulative count of pig carcasses detected during the shift (count_carcass); 2) Test result 2: converted carcass length (length_carcass); 3) Detection time 2: the time when the detection is completed (time_carcass_detected).
[0033] For each test result of the detection device 1, record the following information: 1) Detection count 1: the cumulative count of hooks detected during the shift, count_hook; 2) Detection time 1: The time when the detection is completed (time_hook_detected).
[0034] The detection results of the slaughter line motion encoder record the following information: 1) Whether the killing line is running: When the killing line is detected to be running for a period of time, such as the killing line is detected to be running for more than 3 seconds, it is determined that the killing line is running; 2) Slaughter line running speed: after the slaughter line is detected, the current slaughter line running speed; 3) Suspended operation of the slaughter line: If the slaughter line operation is not detected for more than 2 seconds continuously, it is determined that the slaughter line operation is suspended; if the slaughter line operation is detected for more than 2 seconds continuously after the suspension, it is determined that the slaughter line operation is resumed; 4) Slaughter line suspension time period: When the slaughter line is suspended, the slaughter line suspension time is recorded; when the slaughter line resumes operation, the slaughter line resumption time is recorded; the period between the two times is the slaughter line suspension time period.
[0035] After obtaining the above information, it can be determined whether there is a pig carcass hanging on the current hook.
[0036] First, in the pig carcass detection step, the pig carcass is detected by the second detection device. After the pig carcass is detected, the cumulative count of the pig carcass is increased by one to determine the length of the pig carcass and record the detection time time_carcass_detected.
[0037] Then, in the hook detection step, the detection device 1 performs hook detection, and when a hook is detected passing through, the accumulated count of hooks detected is increased by one, and the detection time time_hook_detected is recorded.
[0038] Next, the pig hanging on the hook determination step is performed. If a pig carcass is detected in the pig carcass detection step, a hook is detected in the hook detection step, and (time_hook_detected - time_carcass_detected) is greater than or equal to the time required for the hook to move from detection device 2 to detection device 1, it can be determined that a pig carcass is hanging on the hook. Otherwise, the hook is determined to be empty and no coding is required.
[0039] Next, the automatic coding judgment step. If there is a pig carcass hanging on the hook and the pig carcass is suitable for coding, the main controller or the PLC controller has not started to suspend automatic coding, the inkjet printer has not issued a fault alarm, and the remaining ink in the ink cartridge of the inkjet printer also meets the coding requirements, then the automatic coding can be started, otherwise the automatic coding is suspended. After the automatic coding is completed, the status of the pig carcass is marked as automatically coded, and the coding time and the traceability code printed on the pig carcass are recorded. If the automatic coding is suspended, the status of the pig carcass is marked as not coded, and the traceability code of the pig carcass is recorded. The information is pushed to the handheld coding device 7. After receiving the coding task, the handheld coding device 7 issues an operation reminder. After receiving the reminder, the staff uses the handheld coding device to perform the coding operation, completes the coding task, and marks the status of the pig carcass as manually coded, and records the manual coding time.
[0040] From the above description, the hook sequence can be used as the minimum granularity of management. The status of each hook includes: serial number, whether a pig carcass is hung, whether coding is performed, coding time, coding content, whether coding is abnormal, etc. With the status sequence of the hook, we can obtain information such as the pig carcass sequence and coding sequence.
[0041] Correct coding and consistent alignment of information such as carcasses and traceability codes are also closely related to the operating status of the slaughter line. If the slaughter line is paused and then restarted, many problems can arise. First, if the slaughter line is paused immediately after Detection Device 2 detects a carcass, the time (time_hook_detected - time_carcass_detected) will be very long, potentially leading to numerous unexpected situations and inaccuracies in the hook-hanging pig determination step and the automatic coding determination step. Second, if Detection Device 1 detects a hook, the automatic coding determination step determines that coding is suitable and initiates automatic coding, pausing the production line. This may cause Automatic Coding Device 2 to continue moving forward with the carcass.
[0042] In order to better complete the marking and reduce data confusion, a slaughter line operation status detection step is also required, which determines whether the slaughter line is operating normally. The first method is to obtain the detection result of the slaughter line motion encoder to determine whether the slaughter line is running and is not in a paused state, and then judge that the slaughter line is operating normally. The second method is that if the pig carcass detection step detects that a pig carcass has passed within a long period of time, such as 5 minutes, then the slaughter line is considered to be operating normally. The third method is that if the hook detection step detects that a hook has passed within a long period of time, such as 5 minutes, then the slaughter line is considered to be operating normally. In this way, the slaughter line operation status detection step can be added to the previous steps. If the slaughter line is not operating normally, the aforementioned judgment step needs to comprehensively consider the slaughter line operation status to make a judgment.
[0043] In the automatic coding judgment step, if the current automatic coding is paused, manual coding needs to be prompted, which can be achieved through the alarm device of the PLC controller.
[0044] Automatic coding requires conditional testing, such as whether a suitable pig carcass is hung on the hook, whether the main controller or PLC has activated or suspended automatic coding, whether the printer has issued a fault alarm, and whether the remaining ink in the printer cartridge meets coding requirements. Generally speaking, automatic coding condition testing includes three main categories: pig carcass testing, PLC self-testing, and printer testing. When an anomaly is detected, different alarm signals can be issued depending on the severity of the anomaly.
[0045] In order to correctly execute the complete pig carcass coding process, before coding, it is necessary to first establish a coding device combination of the automatic coding device 2 and the handheld coding device 7. When the automatic coding device 2 cannot perform the coding task, the uncoded pig carcass information is pushed to the handheld coding device 7, and the handheld coding device 2 completes the coding. Alternatively, at the beginning, after the automatic coding device 2 and the handheld coding device 7 establish the coding device combination, the main controller transmits the coding information to the automatic coding device 2 and the handheld coding device 7. If the automatic coding device 2 fails to print, the handheld coding device 7 will query and discover the missing code and promptly start manual coding.
[0046] Figure 7 The following is a flow chart of the coding method of the present invention. First, the coding process starts, including self-testing, data loading, and automatic coding equipment warm-up. The combined coding equipment is then checked to see if it is online. Here, the automatic coding device is the master device, and the handheld coding device is the slave device. After the master and slave devices are configured, the master device will detect whether the paired device is online upon startup. If so, both devices execute the coding task together. If not, the fully automatic coding device can also perform the coding task independently. Next, the system begins hook detection, pig carcass detection, and slaughter line movement detection. These three detection tasks are performed simultaneously. The hook is then checked to see if a pig carcass is hanging on the hook. If so, an automatic coding determination is performed. If not, the hook is unloaded and unsuitable for coding, and the hook detection, pig carcass detection, and slaughter line movement detection are continued. Next, an automatic coding determination is performed. If so, automatic coding is performed and recorded. If not, a reminder is given and manual coding is performed and recorded, or the task is skipped. The conditions for automatic coding judgment are based on actual needs. As mentioned above, the automatic coding condition detection mainly includes three categories: pig carcass detection, PLC self-detection and inkjet printer detection.
[0047] Previously, automatic or manual coding was selected mainly by detecting coding conditions. From a technical perspective, automatic coding is not as flexible as manual coding. Therefore, for different coding contents, it is also necessary to select automatic or manual coding to better complete the coding task. For example, the printing of different brand logos and different quality logos on pig carcasses mentioned in the background technology. The following describes the technical implementation in this scenario.
[0048] There are five types of pig carcass branding: butcher's brand, pig dealer's brand, slaughterhouse brand, industry-specific slaughterhouse or pork grading brand, and pig breed marking. First, let's describe butcher's brand printing. There are generally three methods to choose from.
[0049] Method 1: Fusion automatic synchronous printing, that is, the badge logo and brand logo are merged into one pattern and then printed according to the automatic printing method described above. First, according to the slaughtering task sequence of the slaughtering line, pigs from different butchers will be slaughtered at different time periods. During slaughtering production, the coding server will obtain the slaughtering task sequence from the production management server, and determine which butcher the different pigs belong to based on the slaughtering task sequence, and whether the brand logo needs to be printed. If so, the corresponding brand logo is obtained and combined with other seal logo contents to be printed to generate a printing pattern, which is sent to the first coding device and the second coding device. When a pig carcass that needs to be printed with a brand logo according to the slaughtering task sequence passes through the coding area, the first coding device or the second coding device performs the corresponding coding operation, printing the corresponding brand logo on the pig carcass that needs to be printed with a brand logo, and not printing the brand logo on the pig carcass that does not need to be printed with a brand logo, but only printing a fixed seal logo.
[0050] Figure 8 This is a flowchart for Method 1, which integrates automatic and synchronous printing. First, the carcass's stamp identification and brand information are acquired. Then, a print image containing the stamp identification and brand information is generated and distributed to coding devices A and B, or more coding devices, located on the slaughter line. Finally, depending on the line's operating conditions, coding device A, B, or one of the more coding devices prints the print image onto the carcass's surface. Typically, coding device A is an automatic printer, and coding device B is a manual printer.
[0051] Method 2: Fusion manual simultaneous printing: This involves combining the badge and brand logo into a single pattern, which is then printed by a handheld device according to the butcher's brand requirements. Carcasses with badges but no brand logo are then printed by automated equipment. Generally speaking, automated coding is suitable for printing fixed content. Adding the brand logo changes the length of the printed pattern, impacting the automated coding equipment's operation. For carcasses requiring brand logos, manual coding can be used, and the automated coding system can skip the process by not coding the carcasses.
[0052] Figure 9 This is a flowchart for Method 2, which incorporates manual synchronous printing. First, the carcass stamp identification and brand information are acquired. Then, a stamp identification image is generated and distributed to printer A. A brand information image is generated and distributed to printer B. Finally, printers A and B each print the image onto the carcass skin. Typically, printer A is an automatic printer, and printer B is a manual printer.
[0053] Method three: independent manual asynchronous printing, that is, the fixed seal mark is printed by the automatic inkjet printer, while the brand mark is printed by the manual inkjet printer. In this way, during slaughter production, the inkjet printer server will obtain the slaughter task sequence from the production management server, and determine which butcher the different pigs belong to based on the slaughter task sequence, and whether the brand mark needs to be printed. If so, the corresponding brand mark is obtained, and a printing pattern is generated by combining the brand mark and seal mark. The pattern is sent to the first and second inkjet printers. When a pig carcass that needs to be printed with a brand mark according to the slaughter task sequence passes through the coding area, the first or second inkjet printer prints the corresponding seal mark, and the second inkjet printer manually prints the corresponding brand mark.
[0054] Figure 10 This is a flowchart for independent manual asynchronous printing for method three. First, the carcass stamp identification information and brand information are obtained; then, a print image of the stamp identification information is generated and distributed to coding device A; a print image including the stamp identification information and brand information is generated and distributed to coding device B; finally, a determination is made as to whether the carcass contains brand information. If so, coding device B prints the print image onto the carcass skin; if not, coding device A prints the print image onto the carcass skin. Typically, coding device A is an automatic coding device, and coding device B is a manual coding device. Here, the determination step can also be placed before generating the print image including the stamp identification information and brand information and distributing it to coding device B. This is because if there is no brand information, there is no need to generate a print image; coding device A can simply print it directly.
[0055] The above three methods are just examples, not exhaustive. Automatic or manual, integrated or independent, synchronous or asynchronous, these permutations and combinations are beyond the three methods.
[0056] Alternatively, if only a manual inkjet printer is available, the manual inkjet printer will perform the coding task. The inkjet printer server will receive the slaughtering task ranking from the production management server. Based on the slaughtering task ranking, it will determine which butcher each pig belongs to and whether brand identification is required. If so, it will retrieve the corresponding brand identification, combine it with the seal identification, and generate a print pattern. This pattern is then sent to the manual inkjet printer, which then applies the corresponding brand and seal identification to each butcher's pig.
[0057] The automatic coding device generally has a scraping and cleaning action for the carcass skin. When the coding action is not being performed, the scraping and cleaning action can continue to be performed, which facilitates the subsequent manual coding device to perform the coding work.
[0058] The printing method for the pig vendor's brand logo is basically the same as that for the butcher's brand logo.
[0059] Regarding the slaughterhouse's brand identity, the quality inspection seal in the seal logo already represents the slaughterhouse's brand. However, all slaughterhouses have the seal logo printed, which cannot reflect the different management levels of the slaughterhouse. Therefore, the slaughterhouse's own brand can also be printed separately. Because current inkjet coding is based on slaughterhouse granularity management, all pigs slaughtered from a slaughterhouse are stamped with the same slaughterhouse seal logo or slaughterhouse brand logo before leaving the factory, so it can be printed as required without going through the production management server.
[0060] For the industry-wide slaughterhouse grading management brand, since the grading brand of each slaughterhouse is the same, the current inkjet coding is based on the management of the slaughterhouse granularity. All the pigs slaughtered from a slaughterhouse have the same slaughterhouse seal or slaughterhouse brand logo stamped on them when leaving the factory. The inkjet coding server can print as required after unified settings are made during coding.
[0061] For industry-wide meat grading management brands, since the meat grade of each pig is comprehensively evaluated after slaughter, the quality of pork from each pig is different. Therefore, it is necessary to conduct quality inspection and grading of the pigs slaughtered in the slaughterhouse according to the industry's unified grading standards. Then, the coding server will obtain the traceability code and corresponding grading information of the current coded pig from the production management server. The above three methods are basically suitable for the printing of meat grading management brands.
[0062] For pig breed identification, such as "Liangtouwu" and "Jianli Black Pig," many of which are geographically indicated products, the slaughterhouse's production management system distinguishes each pig's breed. The coding server obtains the slaughter task sequence from the production management server, identifies each pig carcass with a superior breed identification based on the slaughter task sequence, and prints the corresponding superior breed identification as required. The previous three methods are all suitable for printing breed identification.
[0063] In addition, when automatic coding and manual coding are working at the same time, if the livestock carcass coding system is needed, it will prompt the operator to perform manual coding operations in a timely manner to complete the printing of the brand logo.
[0064] It should be noted that the aforementioned seal identification mainly includes quarantine inspection seals and meat quality seals. In addition, they may also include traceability codes. These are printed identically on all pig carcasses, and their effectiveness as branding is very weak. The present invention prints different brands on different carcasses to meet the production management needs of slaughterhouses.
[0065] As can be seen from the previous description, printing multiple and different brand logos is very cumbersome using traditional stamps. However, digital inkjet printing can automatically generate different print images, making it very convenient. Because the main body of the brand logo is different, two or more brand logos may be printed on a pig carcass. In this way, multiple brand logos can be merged first, and then the printing is completed by the inkjet device that performs brand logo printing.
[0066] Automatic laser marking of pork carcasses has also been developed. The method described in this invention can also be implemented using laser marking, or other future marking technologies, and this invention also claims protection for these technologies. Furthermore, while the embodiments use pigs as an example, it can be seen that post-slaughter marking of cattle, sheep, and poultry is also applicable.
[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention. The scope of protection of the present invention shall be based on the scope of protection of the claims.
