Method and device for controlling the working means when filleting fish

Field of application of the invention:

The invention relates to a method and device for controlling the working means when filleting fish in fish processing plants.

Characteristic of the known technical solutions: There are known filleting machines and methods for filleting fish, in which the time for the beginning or ending of the free cutting of the fillets in the region of the end of the end of the end of the stomach takes place by scanning the strip containing the spokes. The button is purposefully connected to the rib knives and or guide flaps. It protrudes into the gap formed by the abdominal cavity guides and is pivotally mounted transversely to the transport direction. This technique is set forth in DD Patent No. 111280. In another method included in DD Patent No. 107,590, the pivotally arranged probe element is positioned below the peritoneal ducts with its free end extending across the gap of the peritoneal ducts the cutting area is performed. In the known inventions, the reference base is the abdominal end of the fish, which is especially true for those with an extended abdominal cavity

Meat loss results because the plank cut in the tail area is terminated too late.

Object of the invention

The aim of the invention is to increase the meat yield.

Explanation of the essence of the invention; The invention has for its object to develop a new method with device for controlling the working means depending on the course of the connected to the spine ribs or spinous processes. According to the invention, the control of the flank cut during filleting in dependence on the beginning and end of the cut from the back and / or ventral side position of the ribs or spinous processes in such a way that their course is scanned along the spine. For carrying out the method, a scanning element provided with cutting edges is provided for scanning. In a further embodiment of the invention, the cutting tools for the deepening backcut can be formed as a cutting feeler elements.

Embodiment:

The invention will be explained in more detail by an embodiment with drawing. 1 is a simplified side view of FIG. 2 is a simplified plan view and Fig. 3 is a section A-A of Fig. 2 with fish in an enlarged view

In a machine part, not shown, are paired abdominal and back knife 1 arranged one above the other; 2 installed behind these drag knife 3 for a deepening backcut and saddle-shaped guides 4- flank knife 5 is provided. Between the drag and flank knives 3; 5, a probe element 6 is pivotally suspended in the transport direction.

Mode of action:

A beheaded fish 7 gets ahead with its cut side, by means not shown transport in the loading area of the abdominal and back knife 1; 2. It is measured size dependent on a known, not shown control system and the measurement result used for vertical adjustment of the dorsal blade 2. In the area of the abdominal and back knife 1; 2 takes place the cutting of the fish 7 from above and below along the spine 8 · At the end of the abdominal cavity, the dorsal blade 2 pivot down, the sections of the abdominal and back knife 1; 2 converge. In the tail area, the spine 8 is cut free from both sides. At the same time grab the drag knife 3 in the column of dorsal cuts so ek that the still adhering to the spine 8 meat bands are separated. After passing the abdominal and back knife 1; 2 passes the fish 7 on the guide plates 4 sliding into the working area of the probe element 6 "This is deflected by the ribs of the fish 7 in the transport direction and extends in the gap of the back section. About a case triggered signal the guide plates 4 are controlled in a known manner down and released the cutting edges of the flank knife. At the end of the ribs, the probe element 6 pivots back into the starting position. The still applied signal is canceled, the guide plates 4- return to their original position and the flank cut runs out at the end of the ribs. It is also possible to scan the ribbed position from the ventral side. In this case, the free end of the probe element 6 is formed as a cutting edge. As a further embodiment, the drag knife 3 can take over the function of the probe element 6. When controlling the flank knives 5 as a function of the position of the ribs, a higher meat yield is achieved, in particular in fish 7 with an extended abdominal cavity. If the scanning from above, soiling of the tools are reduced.

Claims (2)

21 1280 Invention claim: Method for controlling the working means when filleting fish, cutting the fish from above along the spinal column and from below to the spinal column, performing a deepening of the back and then cutting the fillets free of the ribs and spinous processes, characterized in that the control of the Flank cut as a function of the beginning and end of the spine (8) connected and cut free from the back and / or ventral side ribs or spinous processes by scanning them along the spine (8). 2. Apparatus for carrying out the method according to item 1, characterized in that for scanning a cutting edge exhibiting Tastelement (6) is provided or that the cutting tools (3) are formed for the deepening backcut as cutting sensing elements (6).
