(54) Apparatus for processing the salt, spiced or otherwise prepared fish, preferably herring.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for treating salted, seasoned or otherwise prepared fish, preferably herring, where the head bone is removed and the two fillets are interconnected in the spine, and from which fish the skin is to be removed by transporting the fillets through a denaturing plant. by contacting a liquid, preferably acetic or citric acid, with the g skin, for example by duching, in which apparatus is placed q at least one transport path for transporting the fish past a fin cutting device for cutting its spine-shaped ridges are provided by rotating blades, having two inserts spaced apart to form a gap.

t 3 2 143833

The prior art devices of this kind have the disadvantage that there is a clogging in the gap between the two blades, which in the last working operation cut off the fish's dorsal fin.

The invention has for its object to eliminate this disadvantage and to provide an apparatus which continuously cleans the space between the two blades.

This is achieved according to the invention by means of an apparatus, characterized in that a scraper is arranged in connection with each knife which extends between the blades and from above into the plane of the conveying path to 'immediately cut off the dorsal fin parts immediately after cutting. away from the knife.

The invention will now be described in more detail with reference to the drawing, in which 1 is a side view of an apparatus according to the invention; and FIG. 2 shows the same, seen from the front.

The drawing shows a machine 1 for carrying out the denaturation process. Since the construction and operation of such machines is well known, only the front end portion of the machine 1 and a conveyor belt included therein and an end roller 6 over which the conveyor belt 3 runs are shown. The portion 8 of the conveyor belt 3, which carries fish, runs essentially horizontally through the machine 1.

In connection with the denaturation, to achieve a fully automatic treatment of the fish, according to the invention, the fish are transported along a trajectory, so that each fish passes a fin cutting device which divides the fish into three parts, namely a part which exhibits the dorsal fin and which is disposed of as waste. , and two fishing side portions which are transported to the denaturing plant and further therein to denaturing.

A fine cutting device for carrying out this treatment consists of a machine frame 25 (schematically shown only) which is positioned to or fixedly mounted on the machine 1. The machine frame 25 has a driven conveyor belt 26 which extends endlessly over rollers 27, 28 and the guide roller 29 These rollers 27 to 29 are mounted on the machine frame 25 and at least one of them is driven to propel the conveyor belt, so that its upper portion moves in the direction of arrow B and forms a conveying portion or conveying path 30 extending from a fish loading table. 51 to the conveying portion 8 of the conveyor belt 3.

The conveyor belt 26 consists of a plurality of adjacent endless conveying means 31, e.g. tubular plastic strands, and the belt is divided by stationary elongated guide members 32 into longitudinal sections 33, 34, 35, 36 with a number, e.g., six transport means 31 in each section.

The control means 32 preferably rise in level with the upper side of the transporting part, d, v.s. in level with the conveying path 30 formed by said part, or it protrudes slightly above said top side.

The control means 32 are directed to a fin-cutter assembly 37 having a plurality of cutting means in the form of blades 38 mounted on a machine-stand-mounted shaft 39 driven by a drive assembly (not shown). Each knife 38 has two circular inserts 40 and is connected to a guide member 32 so that this is directed to the space between the inserts 40. The size of this space can be varied by at least one of the inserts 40 in each knife 38 being slidably mounted on the shaft. 39 and can be tightened by means of a tightening screw 41 or so. like. Each cutter 40 projects below said transport path 30 and rotates in arrow direction C.

To guide cut fins downward, elongate scrapers 42 are placed into the blades 38 which are mounted above the holders 43 on the machine frame 25 above the conveying path 30. Each scraper 42 projects in the direction of one of the blades 38 and simultaneously downwards, between the blades 40 at the height of the conveyor web 30 or rather below the plane of the conveyor web 30. The holders 43 are preferably arranged such that all of the scraps 42 or each scraper 42 can be individually adjusted in different angular positions and / or different height positions relative to the conveying path 30.

The fin cutting unit 37 also has a knife 44 serving as a knife protection, which over hinges 45 or so. like. is pivotally connected to the machine frame 25, the sheath 44 can be pivoted upwards from its protective position in arrow direction D to expose the blades 38 so that they can be easily cleaned or adjusted as needed.

To ensure removal of cut fins, it is advantageous to equip the fin cutting unit 37 with a coil device 46, preferably consisting of a conduit 47 fixed or pivotally mounted on the underside of the sheath 44. Pipeline 47 has nozzles 48 directing relatively strong fluid jets 49 from above and inclined downwards between the cutters 40 of the blades 38 so that a jet 49 can
