Description

Technical Field

[0001] This invention relates to the field of salmon processing equipment technology, specifically a flexible intelligent production line for salmon processing. Background Art

[0002] Salmon is a common name for some salmonid fish, named for the similarity in pronunciation to the English word "salmon." It is one of the world's most prized fish, often referred to as the "King of Fish" or "Gold of the Water." In recent years, with the increasing development of the raw food industry in China, salmon has become a top choice for raw food restaurants. Due to its high protein and unsaturated fat content, and its high water content making it prone to spoilage, salmon easily deteriorates and rots if not properly preserved after capture. Therefore, maximizing processing speed—quickly selecting, weighing, and packaging the fish to minimize the time the fillets are exposed to the external environment—is crucial for salmon processing.

[0003] Currently, salmon processing mostly involves manual weighing, grading, and packaging. This grading method is highly susceptible to cross-contamination due to insufficient hand disinfection by employees, leading to a decrease in product qualification rate. The grading and packaging process requires different weights and packaging specifications according to order requirements, and the high-intensity work of employees also poses a potential risk of data recording errors. Therefore, technological improvements are urgently needed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a flexible intelligent production line for salmon processing. It can solve the problems of low processing efficiency and numerous processing steps in traditional salmon processing, the problem of long overall processing time in traditional salmon processing which makes salmon prone to spoilage, and the problem of data recording errors that are easy to occur when workers are working under high intensity for long periods of time.

[0022] Preferably, the pallet loading area is located at the top of the palletizing robot, and the pallet unloading machine is located at the top of the palletizing robot.

[0023] Working Principle: This flexible intelligent salmon processing production line first uses a forklift to lift and transport the insulated salmon crates to the unloading platform. Pressing a remote control sends a tilting command, and the receiving device communicates with the PLC to activate the hydraulic station. The hydraulic solenoid valves open, raising the hydraulic cylinders on both sides and driving the tilting platform forward. Anti-tipping crossbars are installed above the tilting platform to prevent the insulated crates from tipping over during the tilting process. The PLC's lifting command is executed in two stages. The first stage of lifting lasts for 10 seconds, then the second stage is executed until the proximity switch on the unloading platform's support communicates with the tilting platform. The system maintains the tilting posture for another 10 seconds, then the cylinders descend and the tilting platform returns to its original position. The raw salmon is then transported by a conveyor belt to each gutting platform. Each gutting platform has a raw salmon distribution lever. Employees... Select or turn on / off the raw fish distribution lever according to the quantity of raw materials at the workstation. Raw materials not fully distributed at the front end are automatically sent to the final visceration platform. However, after visceration, the raw fish have a large amount of blood, fish feces, uneaten feed, and other dirt attached to their abdominal cavity and surface. The viscerated raw fish conveyor belt is equipped with four spray devices to rinse and clean the surface of the fish and the conveyor belt. The product is lifted to the spiral cleaning tank by an lifting conveyor belt, which uses a mesh conveyor belt. During the lifting process, the wastewater on the surface of the viscerated raw fish is promptly drained, extending the service life of the water in the spiral cleaning tank. An ice-adding system is installed at the top of the spiral cleaning tank to control the temperature of the water inside. The Roots blower installed in the tank continuously and efficiently forms a high-speed jet of water inside the tank, causing the fish to rotate and generating a large number of microbubbles. The bursting of the microbubbles generates a powerful shock. The spiral washing system uses shock waves to thoroughly clean the surface and abdominal cavity of the fish, causing blood and impurities to float to the surface and flow out through the overflow outlet. Water replenishment pipes promptly replenish lost water. Each tank has a landing net at the end to scoop out the fish and transfer them to the next process. The landing net then transports the fish along a fish chute to the selection platform. On the selection platform, staff use external senses to inspect and screen for deformed, physically damaged, or diseased fish. Substandard fish are moved through a non-conforming product chute and packaged separately. Conforming fish slide into a temporary storage tank, triggering a baffle. A proximity switch on the baffle closes and communicates with the PLC. The PLC sends a signal to a photoelectric sensor on the fish conveyor belt. The photoelectric sensor detects that there are no fish in the empty trough of the fish conveyor belt. The PLC activates the locking cylinder, which retracts the lower door of the raw fish storage tank, allowing the raw fish to fall accurately into the empty trough of the conveyor belt. The photoelectric sensor then communicates with the PLC again, confirming the action is complete. The locking cylinder then opens, awaiting the next action. This design features two sets of raw fish storage tanks, enabling efficient sorting by two workers. The photoelectric sensor ensures that each baffle on the draining conveyor belt contains only one raw fish. During the upward movement of the draining conveyor belt, residual water in the abdominal cavity is drained. The equidistant baffle design of the conveyor belt effectively aids in the accuracy of the next weighing process, preventing multiple fish from being weighed together and causing imbalance. The corrective conveyor belt must ensure that the raw fish entering the belt scale is centered on the scale and does not come into contact with other parts of the scale, as this could cause weight errors affecting the system's grading judgment.During the process of the raw fish being transported from the drain belt to the corrective conveyor belt, due to inertia, the fish are prone to lateral movement or even tilting. The left and right guide baffles on the conveyor belt can correct and center the fish's position. However, due to the tilting issue during the initial descent, two fish may appear head-to-tail or overlap on the conveyor belt. Although the guide baffles have corrected and centered the fish, two fish may still enter the belt scale connectedly, causing errors. Therefore, the corrective conveyor belt and the belt scale are designed to operate at different speeds. When the fish enter the belt scale, the higher speed of the belt scale quickly separates the connected products, achieving accurate weighing. The raw fish then passes through the transmission system's weighing sensors, which rapidly connect and record the values ​​to the electronic control system. The electronic control system monitors all sensors and pneumatic components on the production line. The system effectively controls components such as motors and printing systems, and sequentially turns on or off electrical components of each subsystem based on sensor feedback signals. The electrical control system consists of an industrial computer, PLC, frequency converter, and relays. It can record and output the number and weight of individual fish, single-shift production reports, and production area temperature displays in real time. The system has multiple pre-set programs to track, analyze, and execute real-time data, truly achieving flexible matching of grading specifications, grading modules, and grading weights. After the fish are weighed by a belt scale, the electrical control system controls the pneumatic grading lever on the grading conveyor belt to prevent the fish from entering the designated grading port. Photoelectric sensors on both sides of the grading port chute record the number of fish. When the system reaches the preset value, the temporary storage tank opens, and the fish falls into the foam box. The empty foam box is then transported by an empty container. The conveyor belt delivers the fish to the boxing waiting area. The empty box waiting area contains pneumatic clamping cylinders and weighing sensors on both sides of the foam box. After the foam box is weighed both empty and full in the waiting area, the data is transmitted to the electronic control system. The electronic control system subtracts the two weights and communicates with the printing system. Simultaneously, the electronic control system, according to a preset program, transports the specified size of raw fish via a grading conveyor belt to the end-of-line insulated box turnover weighing module. This module can perform functions such as temporary storage, weighing, and boxing. When the raw fish arrives at the raw fish temporary storage tank, the weighing sensor of the bucket scale communicates with the electronic control system to provide feedback on the scale's working status. If the weight of the raw fish in the bucket scale has reached the system's internal threshold, the weighing result is directly communicated to the electronic control system and the printer, and the cylinder closes the raw fish temporary storage tank door, waiting for the weighing process to complete. Otherwise, the system opens the raw fish temporary storage tank. The system operates until the weight of the raw fish in the weighing bin reaches the system's preset range. Simultaneously, the independent printing system uses a manual labeling mode. The printing drive engine receives the weighing value from the electronic control system, converts it into a preset label version, and drives the label transmission mechanism to deliver blank labels to the print head for printing. After printing, the pneumatic labeling mechanism uses a negative pressure device to attract the label, and a cylinder affixes the label to the designated area of ​​the foam box. Empty boxes and lids are stored in the outer packaging material warehouse. Empty boxes and lids are manually fed into the circulating elevator's loading area. The elevator then delivers materials to the empty box and lid conveyor belt. Both the empty box conveyor belt and the empty box waiting area are equipped with photoelectric sensors. When a sensor detects a shortage of boxes at a workstation, the deflecting conveyor belt lifts the empty box and delivers it to the empty box waiting area.The next box is pushed along the empty box conveyor belt one by one. Simultaneously, the raw fish passes through the transmission system, where a weighing sensor quickly connects the data to the electronic control subsystem. The subsystem reads the empty box weight and net weight from the label's QR code. The weighing sensor subtracts the empty box weight from the actual weight and compares it to the net weight on the label. If the values ​​match, the subsystem automatically releases the box. If the weight exceeds the preset range, the subsystem issues an audible and visual alarm and deletes and records the box's data from the shift report in the electronic control system. The subsystem also has an independent weighing and labeling function, which can be used as a small-scale sales system. Relevant data can be promptly fed back into the shift report for inventory management. Furthermore, when the raw fish foam box, having passed metal detector inspection, reaches the end, an optical scanning transmission... The sensor identifies the box label, and the relevant information communicates with the electronic control subsystem. The electronic control subsystem then controls the palletizing robot to pick up the original fish foam box and place it in the designated pallet loading area. Simultaneously, the box data is transmitted to the electronic control system for comparison with the scanning results from the re-inspection station. Once the pallet reaches the preset layer height, the subsystem activates the pallet conveyor belt to deliver it to the forklift work area. The palletizing robot then automatically turns to the pallet unpacking machine to pick up empty pallets and place them in the pallet loading area where there are no pallets. Pallets in the unpacking area are placed manually. Each time an empty pallet is picked up, the unpacking machine automatically replenishes the empty pallet to the waiting area. If the optical scanning sensor cannot correctly identify the label, the pallet is sent to the manual palletizing conveyor belt via a steering conveyor belt to await manual palletizing.
