Sorting apparatus for alive fish
The present invention is related to a sorting apparatus for alive fish, according to the preamble of claim 1.
Background
Within the fish industry it is often required to sort fish into batches according to size, number, etc., i.e. grading, wherein the number of fishes in a batch and size-range are variable. There have over the years been proposed different solutions for sorting, grading, counting, etc. within the fish industry. When sorting alive fish, it is a requirement that the solutions should be able to process large amounts of fish over a short time interval. Further, a biomass of alive fish, due to the properties and behaviour of the alive fish, behaves different than any other object, organism or item, hereunder dead, anaesthetized or stunned fish that do not move, that are graded or sorted.
Presently, there is also an increasing focus on fish welfare, and there are now requirements, as, e.g., described in:
https://nofima.no/wp-content/uploads/2021/05/FISHWELL-Welfare-indicators-for-farmed-Atlantic-salmon-November-2018.pdf and
https://nofima.no/wp-content/uploads/2021/05/Welfare-Indicators-for-farmed-rainbow-trout-Noble-et-al.-2020.pdf,
defining welfare indicators also related sorting, hereunder grading, that have to be meet by the fish industry.
In US 2008283453 A1 is disclosed a grading apparatus grading apparatus for grading objects such as in particular fish or shrimp in respect of their size, comprising a plurality of juxtaposed substantially parallel endless conveyor belts, where each conveyor belt comprises a plurality of hinged segments with a sloping cross-section such that in between each adjacent pair of belts is formed a V-shaped valley with substantially continuous sloping sides.
From NO 319328 B1 is known an apparatus for sorting fish including feeding means, ridged belts, rail guides, sorting chambers, drive means and adjustment mechanisms. The fish are fed to the feeding means and from there onto the ridged belts, which transport it and grade it by thickness into the appropriate grading compartments.
The closest prior art to present invention is found in FI8235U1 and FR975679A.
In FI8235U1 is described a sorting apparatus for sorting products and items, such as e.g. fish, the sorting apparatus comprising a supply unit supplying products or items to be sorted to a sorting device. The sorting device is formed by a motor-driven endless chain and multiple tubes or poles extending with their longitudinal direction in transversal direction of the endless chain (and moving direction thereof) arranged in a raised plane above the mentioned chain. The tubes or poles are arranged to the chain by means of respective vertical supports arranged at both transversal sides of two adjacent chain links, positioning the tubes or poles at a distance above the chain. The mentioned vertical supports also form side walls of the sorting path of the sorting apparatus.
The chain is further so arranged that the chain path enables the spacing between the tubes or poles to increase in the moving direction of the chain.
The solution of FI8235U1 may be used for sorting fish, but is related to dead fish for, e.g., deepfrying, and not alive fish that may move during the sorting process. Further, the solution is not designed for fish welfare and to avoid damages/mechanical affection/wear during the sorting process. E.g., in the FI8235U1 solution, the fish might become hanging after the head over a longer time. The solution of FI8235U1 further suffer from that the solution will not be accurate, due to the sorting is based on vertical supports arranged to the links of the chain. Slack in the chain or wear on the links or vertical supports will affect the accuracy of the sorting/grading. In addition, the wear or slack on different sides of the chain links or vertical supports may result in different sizes of the spacing and thus different sorting/grading close to the respective sides of the sorting device.
In FR975679A is described a method and device for sorting bodies, more particularly dead bodies, such as fish. The device comprises a mobile grid circulating around two drums, wherein the grid comprises transversal tubes or bars arranged parallel to each other, extending between respective links of two chains. The links are designed such that the mentioned tubes or bars are allowed to move in elongated slots of the links via pins. The mentioned tubes or bars are further associated with a lever solution designed to be affected by cams or similar, arranged in connection with the chain, such that when the chains travel in the moving direction, the cams affect the lever solutions affecting the tubes or bars to move in the elongated slots of the links, thus increasing the spacing/gap between the adjacent tubes or bars. In this manner an increasing gap between adjacent tubes or bars is achieved as the mobile grid is rotated in the moving direction, enabling sorting of fish of larger size into different receiving units as the mobile grid travels.
The solution of FR975679A also suffers from the above-mentioned drawbacks of FI8235U1. Further, the solution requires many movable parts to enable the change in the spacing between the adjacent tubes or bars, that will be exposed to mechanical wear, but also exposed to dirt and other objects that may come into the mentioned elongated slots and lever solution, affecting the grating/sorting accuracy.
Accordingly, there is a need for a sorting apparatus enabling accurate sorting of alive fish.
There is further a need for a sorting apparatus for alive fish that meets the requirements of fish welfare.
There is also a need for a sorting apparatus for alive fish that do not expose the alive fish to any mechanical affection/wear during a sorting process.
