Definitions

  • the present invention relates to a fish-cutting machine, particularly for cutting fillets from the backbones of fish.
  • Fish processing operations include the removal of the fish gut or entrails and at times also the heads of the fish. This is done in close conjunction with taking the fish from the water. It is also normal in fish processing to fillet the dead fish. This can be carried out manually or with the aid of mechanical auxiliary devices which are automated to a greater or a lesser extent and which cut the fillets from the fish backbone, normally with the aid of knives or cutting rollers which are mounted in parallel so as to cut right and left fillets from the fish at the same time.
  • Known fish filleting machines normally comprise two parallel cutting rollers or knives which cut along both sides of the fish backbone simultaneously. These cutting rollers or knives are either normally fixedly mounted or are mounted so as to enable the cutters to be adjusted manually to a specific distance apart.
  • the size of the fish to be filleted is not taken into account in the former case, while manual setting of the cutters is difficult to achieve in the latter case, said fish often varying in size and therewith also in the thickness of the backbone. Consequently, when the space between the cutting devices is fixed and the thickness of the backbone varies, the cutting rollers or knives will often either cut into the backbone as the fish is filleted or will leave an unnecessary large amount of flesh on the backbone. This is because the conventional machines do not adapt directly to the thick- ness of the backbone of the fish concerned or any curves or bends which particular fish may exhibit along their backbones. This results in an undesirable irregular cut surface.
  • Machines have also been proposed in which the cutting devices comprise two parallel endless saw blades.
  • the saw blades When filleting the fish, the saw blades are placed against the backbone of the fish, on each side thereof, and as a result of the resilience of the saw blades the blades will follow the backbone of the fish as they move therealong in a more effective manner than the aforesaid cutting rollers or knives.
  • This increases the tolerance with regard to different fish sizes in relation to fixed cutting rollers or knives, and therewith also to the varying thicknesses of the backbones of fish to be filleted.
  • Machines of this latter kind are defined, for instance, in U.S. 3,596,308 and U.S. 4,534,085.
  • One object of the present invention is to provide a machine which will enable fish to be cut or filleted in a more effective, simpler and ergonomically reliable manner without needing to adjust the settings of the machine, even should the fish vary in size, such that the amount of flesh left on the backbone of the fish will always be at a minimum.
  • Another object of the invention is to provide a machine in which fish to be filleted can be fed through the machine without damaging the fillets.
  • a fish filleting machine which includes two mutually parallel and mutually adjacent bandsaw-like devices 1 which are mirror images of each other.
  • Each of the devices 1 comprises a cutting device 4 which extends in an endless loop around a respective pair of wheels 2 and 3 which are spaced vertically in the same plane.
  • the cutting device is comprised of a thin, smooth steel cutting band which has a generally rectangular cross- section and the mutually opposing short profiled sides of which are considerably shorter than the long profile sides.
  • One of the short sides of the cutter band profile forms a cutting surface while one of its long sides forms a surface on which the cutting band abuts the surfaces of the wheels in a respective wheel pair.
  • the respective cutting devices 1 include a motor which transmits rotary movement to one wheel 2 of the wheel pair 2 and 3, while the other, freely running wheel 3 is mounted on a spring suspension.
  • the motor driven wheel 2 drives the cutting band 4. This is made possible by keeping the cutting band constantly under tension between the wheel pairs 2 and 3 with the aid of the spring-loaded suspension means of the freely running wheel 3.
  • the mutually parallel cutting bands 4 move in the same direction in the fish cutting region, this direction being vertically downwards in the case of the illustrated embodiment.
  • the fish filleting machine also includes cooling devices 5 in the form of water hoses arranged in the fish-cutting region and functioning to deliver water for cooling and lubricating purposes, among other things to avoid fish flesh from fastening to the cutting bands and impairing their cutting properties.
  • the illustrated filleting machine also includes a recipro- catingly movable carriage 6 which is supported on runners 7 and the possible directions of movements of which are determined by guide rails 8 in which the runners 7 move.
  • the carriage supports two generally parallel and mutually spaced support rails or bars 9 which extend longitudinally in the direction of carriage movement and against which the fish are intended to be placed.
  • the carriage 6 carrying the support rails 9 is reciprocatingly movable in a direction transversely to the direction of movement of the cutting bands 4 and parallel with the band abutment surfaces.
  • the support rails 9 are mounted on the carriage 6 so as to be able to move on each side of the cutting region defined by the parallel cutting bands 4 and such as to enable the band spacing at the ends the ends of the bands to be adjusted in accordance with varying fish sizes and shapes.
  • the support rails 9 are provided with movable stabilizing devices 10 which assist in stabilizing the narrowing tail part of a fish lying between the rails 9. This arrangement is primarily intended to compensate for non-linear tapering of the fish body.
  • the fish to be filleted, from which the gut or entrails have been removed, are placed on the support rails 9 with the spine of the fish facing downwards and with the head end of the fish facing towards the cutting bands 4.
  • the fish are firmly clamped as the belly parts of the gutted fish are pressed outwards against respective support rails 9 by two maneuverable holding devices or jaws 11, while eliminating the risk of unintentional damage to the fish fillets by the cutting devices at the same time.
  • the holding devices 11 are each manoeuvered individually via a mechanical link system with the aid of two handles 12 mounted on respective sides of the first short side of the carriage.
  • the same handles 12 are also used for pushing and pulling the carriage 6 backwards and forwards in relation to the cutting bands 4.
  • the two cutting bands 4 of the two bandsaw-like cutting devices 1 extend mutually parallel to one another in the cutting region with a band spacing which, when no fish is present between the bands, corresponds to the width of a typical fish backbone.
  • the fish are aligned in the filleting machine, preferably by moving the backbone of the fish in between the parallel cutting bands 4.
  • a hard metal wedge 13 which when the carriage 6 is in its stand-by state is located beneath the cutting region and penetrates in between the cutting bands 4 while functioning to hold the bands apart to an extent which will allow the backbone of the fish to be inserted into the space between the cutting bands.
  • the fish are clamped firmly by the holding devices 11, after having been placed in the filleting machine. These devices hold the two fish fillets apart and press the fillets against respective support rails 9 during the whole of the fish-cutting operation.
  • the cutting bands are moved towards one another in a manner such that the greatest possible surface area of the cutting bands 4 will abut the backbone and cover the greatest possible peripheral area of said backbone. Since that side of respective cutting bands 4 which lies in abutment with the backbone of the fish is relatively large in comparison with that side of the bands which cut through the fish, the cutting bands 4 will not cut pieces of bone from the backbone of the fish, despite the fact that the cutting bands 4 are tensioned relatively firmly against the backbone. This results in the desired effect of minimizing the amount of flesh that remains on the backbone.
  • the cutting, bands 4 are guided by means of two pairs of clamping devices, of which a first pair is located above the fish and a second pair is located beneath the fish.
  • Each pair of clamping devices includes two centrally opposing and mutually coating pressure applicators 14 which, when active, lie against respective cutting bands 4.
  • the pressure parts 14 are com ⁇ prised of a smooth low-friction material and are operated by a foot peddle (not shown) via an intermediate wire or cable.
  • the carriage 16 is moved forwards to its end position wit the aid of the handles 12, wherein the cutting bands 4 in firm conforming abutment with the backbone of the fish on either side thereof will closely follow the backbone and remove the fish fillets. Because of the tension in the cutting bands, the bands will clamp firmly against the sides of the fish and conform to the configuration of the backbone and therewith cut away essentially all flesh therefrom, irrespective of variations in thickness along the backbone or irrespective of variations in the sizes of the backbones of different fish.
  • sliding-type guide devices may also have the form of rollers, wheels, pulleys or the like, for instance. Neither is the invention restricted to filleting of fish which lie on their backs and where cutting of the fish is begun at the head end of the fish, since variants of these features are conceivable within the scope of the invention.
  • certain of the features of the illustrated filleting machine have been described as manually operated, for instance such features as the carriage, the belly clamping devices, the means for moving the cutting devices together, etc., it will be understood that these members of the inventive machine may alternatively be operated pneumati ⁇ cally, electrically, hydraulically for instance, or in some other convenient manner.
