Filleting machine for fish

The invention relates to a filleting machine for filleting and simultaneous cutting out of the flesh bones of fish with one A conveyor for the fish moving in a stretched path, pairs of circular belly and back knives arranged symmetrically to one another, rib knives and herringbone knives enclosing an obtuse angle towards the back of the fish for cutting the meatbones.

In such filleting machines it is important that the meat the fish is obtained with a high yield and is free of bones.

Through the DT PS 1 579 ^ 26 a device for cutting off the Known meat bones and vertebral processes when filleting fish, by means of which fish fillets free of meat bones can be obtained, which no longer need to be inspected.

Such a device is an advantageous solution on board of fishing and processing vessels, in which the possibility of The fastest possible processing of the captured marriage and the saving of expensive and scarce labor is a priority.

When filleting fish on land, at today's fish prices, the fish bones are cut off by cutting off the flukes and conical appendages containing belly flaps incurred losses in meat yield or the like even when they are processed into meatballs. cannot be compensated and therefore not justifiable.

The invention is based on the object during filleting the Safely cut out meat bones with little meat loss.

According to the invention, this object is achieved in that above and below the track of the conveyor, which is designed as a pusher, there are pairs of guide rails for the backbone of the fish, and the meatballs (onrno sser between the fi Ic tiormcssi rn and the rib knives, and. iodom der FIc i scherätmcs se r a Trennme eac r is assigned, which with its peripheral cutting edge touches the peripheral cutting edge of its Flei scherät.messe rs approximately at the point closest to the guide rails.

The advantages achieved with the invention are in particular: that the fish cut by the filleting knife by means of the Pairs of guide rails with its backbone is precisely guided and the meat bones are very safe with curdled losses of fish meat have it cut out.

An embodiment of the invention is shown schematically in the drawing and is described in more detail below. Show it

1 shows a view of the area of the cutting tools of a filleting machine in an oblique parallel projection,

Fig. 2 is a section through the tail part of the fish after his Passage through the filleting knives,

Fig. 3 is a section through the belly part of a fish in the Bone bone knives,

4 shows a section through the belly part of a fish in the rib knives.

In the machine frame, not shown, there is a plurality of sliding saddles 16 supporting, endless conveyors, deflected around two horizontal axes, arranged and continuously driven. Below the track of the sliding saddle 16 are belly filleting knives 1 arranged in pairs, lower guide rail. 8 and fillet discharge belts 7, above the same also paired back fillet knives 2, upper guide rails 9 and rib knives 10, 11 are arranged.

In front of the belly filleting knives 1 and the back filleting knives 2 there is a pair of laterally resiliently flexible insertion flaps 17,

in front of these is the dispatch table 12, the horizontal surface of which is in the area the path of the sliding saddle 16 is interrupted by the floor compartment formed by the two inclined side walls 14 and provided with a slide 15 at the bottom.

Mad Area zvischsn ds π Fi Is νί «» νϊ · «Γϊϊ 1 and 2 and the nipping knives 10 a pair of circular knives placed at an acute angle to one another are arranged on both sides of the upper guide rails 9, each of which has an upper meat bone 3> 4 and the lower cutting knife 5.6 are touching with their circumferential cutting edges. Difc bearings, controls and drives for the filleting knives 1 and 2, the meat bone knives 3 and 4, the cutting knives 5 and 6 and the filet removal belts 7 are the Gone away for the sake of clarity.

The mode of operation of the device is as follows:

A decapitated and gutted fish will open with its abdominal cavity the sliding saddle 16 se placed that his tail to the right wfeiat and the fish ait its belly end at the one in front At the end of the sliding saddle. When the fish is advanced in the direction of the arrow, it is aligned by the pair of insertion flaps and cut by the two pairs of circular knives 1 and 2 next to the belly and back spokes. The guide rails 8 and 9 penetrating into these incisions take the spine of the fish between them and lead by means of the same the fish in the straight path ir direction of the rib knives 10, 11. When the push saddle 16 with the Fish reaches the meatbone knives 3, 4 with their cutting knives 5, 6, these are controlled from their pivoted-out position into the position shown in FIG. 3 and cut out as the fish continues to advance the sides of which each have a wedge-shaped strip that contains the meat bones. The so-called from the back Fish that have been cut free and freed from the meat bones reach the two when the push saddle 16 is further advanced Rib knives 10, 11, which with their tips over the lateral vertebral processes of the dorsal vertebrae peel the fish meat from the same and the ribs and thus the two fillets from loosen the bone structure so that each one of the fillet discharge belts for example, can be fed to a skinning machine.
