Method and device for fish management

Field of application of the invention:

The invention relates to a method and a device for fish management in the field of abdominal knife station of fish processing machines.

Characteristics of the known technical solutions: There are several methods and devices for the correct guidance of the fish in the field of fishing positions in fish processing machines are known, which take into account the different fish sizes and types. In a known device, the lateral guidance of the fish is carried out by swung in the transport direction paired centering surfaces, which change their distance from each other in the fish pass. In this device set out in DD application WP A 22 C 212593, it can be seen that the tail part of the fish can not be pivoted into the cutting zone of the cutting tools.

Object of the invention:

The aim of the invention is an improvement of the cut.

Presentation of the Invention:

The invention has for its object to develop a method and an apparatus that ensure a fish-size-dependent swinging and cutting the tail portions of fish in the cutting region of the cutting tools. According to the invention, a fish clamped between two means of transport, decapitated and cut in the abdomen reaches the area of downstream support elements forming an impression channel on the fish, is centered on the height during the transport and then, with the assistance of a pressure element, pivots the pressure points of the support elements in such a way the tail part of the fish is guided size-dependent into the cutting area.

In a further embodiment of the invention, the support elements are arranged under the transport means and protrude into the distance of the means of transport. Likewise, it should be noted that the support members are disc-like and purposefully connected to the pressure element. The adaptation of the support elements to the fish via cylindrical approaches that abut the transport.

It is advantageous to drive the support elements and equip with drivers.

As a further characteristic of the invention, the pressure element is connected to a plurality of independently acting working elements, which are brought into engagement depending on the fish size.

Embodiment:

The invention will be explained in more detail by an embodiment with drawing. FIG. 1 shows a side view of the device with fish. FIG. 2 shows a top view

Fig. 3 is a section A-A of Fig. 1 in an enlarged view

Essential parts of the device are paired, rotatably mounted and disc-like support elements 1; 1 ', a pressure element 2 and paired driven facial diameter 3 »3' · The support elements 1; 1 'are known paired transport 4? 4 'arranged and protrude with their working edges in the distance 5 of the transport 4; 4 ¹ inside. Furthermore, the support elements 1; 1 ¹ for adaptation to the fish 6 at the means of transport 4; 4 'adjacent cylindrical projections 7; 7 'up. The pressure element 2 is connected to two independent working cylinder 8; 9 connected.

Mode of action:

One between the transport means 4; 4 'clamped and measured by a not shown sensing device fish 6 enters the area of the abdominal knife 3; 3 '»is cut on the belly side and from the supporting elements 1 arranged behind it; 1 'an impression channel forming detected. Upon further advancement of the fish 6 is centered and then with the support of zweekbestirar.t with the support elements 1; 1 ¹ cooperating pressure element 2 to the pressure points 10 of the support elements 1; 1 'fish size-dependent in the cutting area of the abdominal knife 3; 3 'out. Depending on the determined fish size, the associated working cylinder 8; 9 put into operation, thus ensuring that the tail portion of the fish 6 comes in the correct position cutting position. For small fish 6, the actuation of the pressure element 2 takes place only via the working cylinder. 3

For larger fish 6 are due to their greater thickness, the transport 4; 4 ^f pressed apart and on the externally applied lugs 7 5 7 'the Stützeleraente 1; 1 'biased.

The new method with device ensures a fish size-dependent cutting of the tail areas of fish 6. The fish hull remains in one

necessary for further processing altitude, which is particularly advantageous for small fish 6 and those with a short abdominal cavity.
