Definitions

  • the present invention relates to an apparatus for filleting fish.
  • “filleting” is intended that the backbone of the fish is cut away so that two fillets remain.
  • An apparatus of this kind includes the means which are set out in the preamble to the accomanying claim 1.
  • This known apparatus allows mechanised filleting of fish at a very high rate of production, i.e. a very large number of fish can be filleted per time unit.
  • the present invention has the object of remedying this drawback and achieving an apparatus which, without lowering the produc ⁇ tion rate of the apparatus, allows cutting away the backbone of the fish so that if not all, at least neraly all of the flesh is in the fillets and not on the backbone.
  • the flesh on the fish is thickest above the backbone, and it is therefore highly desirable that as much of this flesh as possible is included in the fillets, thus keeping their weight as great as possible.
  • Figre 1 is a plan view from above of the apparatus in accordance with the invention.
  • FIG 2 is a side view of the apparatus illustrated in Figure 1
  • FIG. 3 is a detail of the apparatus in accordance with the invention.
  • Figure 4 is an exploded view of a detail of the apparatus in Figure 3,
  • Figure 5 is a schematic, perspective view of a section through a fish of the salmon variety
  • Figure 6 schematically illustrates the setting of the cutting discs in the known apparatus.
  • Figure 7 illustrates the setting of the cutting discs in the inventive apparatus
  • Figure 8 is a plan view from the front illustrating how much flesh remains on the backbone when the cutting discs according to Figure 6 fillet the fish, and
  • Figure 9 illustrates in a plan view from the front how little flesh remains on the backbone when the apparatus in accordance with the invention is utilise .
  • the apparatus includes a stand 1 and two endless belts 2, 3.
  • the belt 2 is extended between two rollers 4, 5, the roller 4 being driven.
  • the belt 3 extends between two rollers 6 and 7, the roller 6 being driven.
  • the belts which are rather wide, are arranged facing each other and together form a conveying path for an unillustrated fish, which is fed into the apparatus at an input 8.
  • the fish is fed in substantially horizonally and with its back or dorsal part facing downwards. The fish may still have its head, but this is not necessary. Pairs of spring biased pressure rollers 9 and 10 urge the belts 2 and 3 towards each other.
  • Two knives 11, 12 in the form of flat discs are arranged downstream of the pair of pressure rollers 10, and are intended for cutting the fillets away from the backbone.
  • the discs are arranged on shafts 13 and 14, which are each mounted on a slide 15 and 16 attached to stand by holders 17 and 18.
  • the respective slide 15, 16 allows adjustment of the distance between the knife discs.
  • An additional pair of pressure rollers 19 urge the endless belts towards the respective knife disc 11 and 12.
  • the fish is thus urged against the outside of the discs and the cut-out backbone falls away by gravity downwards between the knife discs and is discharged via an outlet chute 20 situated under the bottom part of the circumference of the knife dies.
  • the two fillets leave the conveying path via an outlet chute 21.
  • a spreader 22 arranged immediately upstream of the knife discs guides the ventral or "belly" sides of the fish outwards so that the flesh in these portions is not cut or otherwise damaged during passage past the knife discs.
  • a motor 23 drives the rollers 4 and 6 via a belt or chain transmission 24, while another motor 25 drives the shafts 13, 14 via a belt or chain transmission, and thereby the knife discs 11, 12 in the direction noted by the arrow 27.
  • FIG 3 shows the knife discs 11, 12, which are non-rotatably arranged on the respective shaft 13, 14.
  • Each shaft is carried by two bearings 28, 29 arranged on the respective slide 15 and 16.
  • the side 15 is reciprocally movable in the horizonal direction in the plane of the paper, with the aid of a set screw 30.
  • the slide 16 can be reciprocally moved in the plane of the paper by a set screw 31.
  • the mutual spacing of the knife discs 11, 12 is thus set by the set screws 30, 31.
  • the inclination of the knife discs relative a vertical line 32 can be adjusted with the aid of their respective set screws 33 and 34.
  • the screw 33 is threaded into an opening in the holder 17 and has its end surface engaging against the underside of the slide 15.
  • the slide can thus be turned towards the position illustrated by dashed lines, the shaft 13 mounted on it as well as the knife disc 11 thus also turning relative the vertical line 32.
  • the slide 16 can also be turned in a corresponding manner using a set screw 34 for allowing the angular attitude of the knife disc 12 to be adjusted.
  • Figure 4 illustrates the slide 15 dovetailed to, and slidable on, a base 35 which is screwed to the holder 17 by screws 36.
  • a block 37 is screwed to the slide 15 and moves in a groove 38 made in the base 35 for translating the turning movement of the set screw 33 to a rectilinear movement of the slide 15.
  • Elongate holes 39 in the base 35 allow setting the angle of the knife discs in relation to the travelling direction of the fish. This angle is here called the "ploughing angle".
  • Figure 5 illustrates a cutlet 40 cut from a fish body, and its backbone is denoted by the numeral 41.
  • the ventral parts of the fish are denoted by 42 and the dorsal part of the fish by 43.
  • the dashed planes 44 and 45 indicate the planes of the knife discs 11, 12 in the case where the planes are parallell to the vertical line 32 and the ploughing angle is zero degrees, i.e., when the knife discs are seen from above in Figure 1 they are mutually parallel. If the fish is filleted with this adjustment of the knife discs, it is obvious that the flesh volume illustrated by hatching 46 will remain on the cut-out backbone 41. Since the fish flesh is thickest at this place on the fish, it is obvious that an unnecessary amount of flesh remains on the backbone. This is not exonomi- cally advantageous. It is desirable that waste flesh is kept to a minimum.
  • the hatching 50 in Figure 9 illustrates the amount of flesh remaining on the backbone 41 with this setting of the discs 11, 12.
  • the vertical angle is illustrated exaggerated in Figure 9.
  • the knives cut in at the backbone and then cut with the constantly changing curvature up to the dorsal part 43 of the fish.
  • the knife discs cut even more acutely in, and deeper down towards the backbone, and then cut almost parallel up towards the dorsal part 43. The result will be that practically no flesh remains on the backbone.
  • the cutting sequence can be simply demonstrated if one takes a saucer in each hand and puts them in front of oneself, first with the saucers parallel according to Figure 5, and then turning the saucers towrds each other round vertical axes to set the plughing angle, the saucers now having the attitude as in Figure 8.
  • the vertical angle is then set by turning the saucers round horizontal axes so that they assume the position illustrated in Figure 9. It will then be seen that the downward edges of the saucers are practically parallel and that the minimum spacing between the discs is shifted downwards from the position in Figure 8 to the position in Figure 9.

Abstract

Est décrit un appareil pour découper des poissons en filets. La grande arête du poisson est ôtée entre deux disques à couteaux (11, 12), lesquels forment l'un par rapport à l'autre un angle de rognage (47) et également un angle vertical (49). Des moyens sont prévus pour régler lesdits angles ainsi que l'écartement entre les disques à couteaux. Il ne reste ainsi qu'un minimum de chair sur l'arête ôtée.
