Description

Technical Field

[0001] This invention relates to a fish processing line, belonging to the field of processing lines. Background Technology

[0002] For a long time, the fish processing industry has relied on manual labor or a few semi-automated machines for various processes, such as raw material processing, filleting, skinning, and subsequent deep processing. This has resulted in fish processing not being a complete production line, leading to low production efficiency, high labor intensity, difficulty in controlling hygiene conditions during processing, and unstable product quality. Moreover, if it is a semi-automated traditional processing line, there are problems such as poor connection between functional areas and reliance on manual handling for material flow. This results in low processing efficiency, easy cross-contamination, and difficulty in achieving large-scale and standardized production.

[0003] While some automated equipment, such as automatic fish filleting machines and skinning machines, is already in use in fish processing, these machines often operate independently, lacking systematic production line integration and process optimization. This prevents them from achieving continuous, efficient, and clean processing from raw materials to finished products. Therefore, there is an urgent need for an integrated, highly automated, rationally laid-out, and continuously operating fish processing production line to improve overall processing efficiency and ensure product quality and food safety.

The finished products processed by the filleting machine 21 are transported to the skinning machine 25 by the blade conveyor 23 to remove the fish skin. The removed fish skin is discharged through the outlet at the bottom of the skinning machine 25. The fish fillets after removing the fish skin are transported from the skinning machine 25 to the Z-type elevator 27. The Z-type elevator 27 transports the fish fillets to the weighing elevator 28 for weighing and then to the next process.

[0042] like Figure 2 and Figure 3 As shown, the knife conveyor 23, peeling machine 25 and Z-type elevator 27 are connected by a first conveyor plate 24 and a second conveyor plate 26.

The waste elevator 35 is located below the return basket conveyor line 31 and to the right of the middle-layer correction conveyor line 32 and the lower-layer heavy box conveyor line 33. At the same time, the waste elevator 35 and the lower-layer heavy box conveyor line 39 are connected to the return basket conveyor line 31 and the middle-layer correction conveyor line 32. Waste conveyor 34 is vertical and receives waste material from it. Quality inspection machine 37 is located below return basket conveyor 31 and to the right of waste elevator 35. Workstations are provided on both sides of quality inspection machine 37. Elevator 36 is located between quality inspection machine 37 and lower heavy box conveyor 33 and connects quality inspection machine 37 and lower heavy box conveyor 33. A middle layer insect inspection conveyor 38 is provided to the right of quality inspection machine 37. A lower layer qualified conveyor 39 is provided below the middle layer insect inspection conveyor 38. Elevator 36 is provided between quality inspection machine 37 and middle layer insect inspection conveyor 38.

A chute connecting to lower layer qualified conveyor 39 is provided on the middle layer insect inspection conveyor 38. Finished product barrels are placed above the lower layer qualified conveyor 39. A light inspection table is also provided on the middle layer insect inspection conveyor 38.

[0045] The return basket conveyor 31 is used to return subsequent empty baskets to the weighing elevator 28. The Z-type elevator 27 feeds fish fillets onto the weighing elevator 28. Once the weight is reached, the Z-type elevator 27 stops feeding. The weighing elevator 28 opens its chute to receive the fish fillets through the empty baskets fed onto it. Then, the weighing elevator 28 closes its chute, the Z-type elevator 27 continues feeding, and the weighing elevator 28 continues weighing. At the same time, the weighing elevator 28 lowers the fish baskets containing fish to the height of the intermediate correction conveyor 32 and transports them onto the intermediate correction conveyor 32. Then, the weighing elevator 28 returns and repeats the above operation.

[0046] After receiving the fish baskets, the middle-layer correction conveyor line 32 transports the fish baskets to various workstations for cleaning.

[0047] like Figure 4As shown, each workstation of the middle-layer correction conveyor line 32 includes a standing plate 321, a PE cutting board 322, a cleaning water pipe 323, a box frame 324, a waste chute 325, and a finished product trough 326. The standing plate 321 is located on the outermost side of each workstation of the middle-layer correction conveyor line 32. The PE cutting board 322 is located in the middle of the workstation. The box frame 324 and the waste chute 325 are located on both sides of the PE cutting board 322. The waste chute 325 is connected to the waste conveyor line 34. The cleaning water pipe 323 is located above the waste chute 325. The finished product trough 326 is located inside the PE cutting board 322 and is inclined towards the box frame 324.

[0048] During the cleaning process, workers stand on the standing platform 321 and dump all the fish fillets from the conveyed fish baskets onto the PE cutting board 322. The empty baskets are then placed on the rack 324. The fish fillets are washed using the cleaning water pipe 323. Waste is placed in the waste chute 325 and then enters the waste conveyor line 34, which then transports it to the waste elevator 35 to remove the waste. The cleaned finished products are then placed in the finished product trough 326 and enter the rack 324. The fish fillets are placed in empty baskets in section 4, and then the baskets containing the finished products are placed on the lower heavy box conveyor line 33. They are then conveyed to the quality inspection machine 37 via the elevator 36. After quality inspection, the qualified fish fillets are conveyed again via the elevator 36 to the middle insect inspection conveyor 38. Then, the workers pour the qualified fish fillets into the light inspection table for light inspection. The qualified fish fillets enter the finished product barrel on the lower qualified conveyor line 39 through the chute on the middle insect inspection conveyor 38. Finally, the empty baskets are placed on the return basket conveyor line 31 to complete the entire cycle.

[0049] like Figure 2 As shown, the end of the middle layer correction conveyor line 32 is provided with an end stop device 327, which is used to stop the fish basket and prevent it from falling.

[0050] like Figure 2 As shown, the quality inspection machine 37 includes a middle quality inspection conveyor line 371 and a lower quality inspection conveyor line 372. The left end of the middle quality inspection conveyor line 371 is connected to the lower heavy box conveyor line 33 via a hoist 36. The lower quality inspection conveyor line 372 is located below the middle quality inspection conveyor line 371. The right end of the lower quality inspection conveyor line 372 is connected to the middle insect inspection conveyor 38 via a hoist 36.

[0051] The fish baskets containing finished products that enter the quality inspection machine 37 first enter the middle layer quality inspection conveyor line 371. Then, after manual quality inspection, the fish fillets are poured onto the quality inspection table on the middle layer quality inspection conveyor line. The empty baskets are placed on the lower layer quality inspection conveyor line 372. After quality inspection, the qualified fish fillets are transferred through the chute on the middle layer quality inspection conveyor line 371 into the empty baskets on the lower layer quality inspection conveyor line 372. Then, they are conveyed to the middle layer insect inspection conveyor 38 by the elevator 36.

[0052] Meanwhile, the quality inspection machine 37 has a weighing function, which can weigh qualified and unqualified fish fillets.

[0053] like Figure 2 and Figure 3 As shown, the raw fish conveying and distribution area 1 and the slicing and peeling area 2 are specifically connected to the slicing machine 21 through the material distribution device 14. The slicing and peeling area 2 and the deep processing area 3 are specifically connected to the output end of the weighing elevator 28 and the input end of the return basket conveyor line 31 and the middle layer correction conveyor line 32.

[0054] Example 2

[0055] Any of the above fish processing lines also includes a control system, which includes a logic motion calculation control module, a data binding module, a data processing and traceability module, and an employee management performance appraisal and statistics module.

[0056] The logic motion calculation and control module is used to process the logical motion after the transport basket arrives, and to collect information before proceeding to the next step of the motion.

[0057] Data binding module: used to bind the information of the transport basket, the workstation number and the operator information at the workstation, and to bind the information of the transport basket, the weight of qualified products, the weight of unqualified products, the quality inspection workstation number and the quality inspection employee information at the quality inspection workstation.

[0058] The transport basket is the fish basket. The weighing elevator 28 is equipped with a card reader. Each basket has its own information. When the Z-type elevator 27 transports fish fillets to the weighing elevator 28, the card reader first scans the information of the fish basket. Then the weighing elevator 28 weighs the fish fillets. After the set weight is reached, the weighing elevator 28 opens the material chute and receives the fish fillets through the empty baskets transported to the weighing elevator 28. At this time, the system associates the information of the empty basket with the weight of the fish fillets received.

[0059] After the fish baskets enter the middle-level correction conveyor line 32, each station is equipped with a card reader to read the information of the fish baskets and bind this information with the personnel information and station number of the station. After completion, the baskets are transported to the quality inspection machine 37. The quality inspection machine 37 is equipped with the same card reader to read the information of the fish baskets and bind this information with the operator information and station number. It also binds the weight information of qualified and unqualified fish fillets. After completion, the baskets proceed to the next process.

[0060] The logical actions of the entire process are implemented through the logical motion calculation and control module, so as to achieve the process actions after data collection and avoid the situation where process information and actions are mismatched.

[0061] Data processing and traceability module: Based on the bound data, it automatically calculates and accumulates the total processed weight, qualified product weight, unqualified product weight and loss weight for each operator, and can realize traceability function;

[0062] The employee management performance appraisal statistics module is used to calculate the weight data for each operating employee based on the sorted data, and generate employee performance data accordingly.

[0063] The control system also includes an access control module, which is used to set data viewing permissions for the terminal devices at the quality inspection station;

[0064] The terminal device at the quality inspection station is configured to hide the personal information of the trimming operator when displaying processing data from the trimming station, according to the settings of the permission management module.

[0065] This correction station is the station on the middle-level correction conveyor line 32.
