SU923348A3 - Method and apparatus for oriented feeding of fish to fish-dressing machine - Google Patents

Abstract

Fishes with their heads removed are automatically orientated on a conveyor system. The fish first pass through the decapitation stage and are then dropped onto the orientator. This has two conveyor bands along the sides and a support for the fishes belly below. The support has a circular profile along which the fish is pulled. It is finally picked up by a profiled wheel which pushes the fish onto the support and inverts the belly. The fish is fed forward onto a slicer to fillet it. The system is of use in factories for preparing fish. It allows precise orientation of the fish.

Description

FIELD OF THE INVENTION The invention relates to the fish industry, in particular to a technique of oriented feeding of fish, mainly cod, to fish dressing machines.

There is a method of oriented feeding in fish processing machines of fish, involving the movement of fish with the support of it in the abdomen and sides 1.

It is also known a device for oriented feeding of fish to fish trimming units, including two longitudinal closed conveyor belts arranged below them to form a feeding chute, a closed bottom conveyor belt and an element 1 above the chute of direction.

The disadvantage of the known method and device for its implementation is that the alignment of the position of the fish when they are fed to the groove is not ensured, since the alignment task is performed by the tilting chutes, which feed the fish into the inlet device inverted by 90 around the longitudinal axis, which cannot be corrected in filing case

fish has a cross section close to round, for example, cod fish, and this leads to a deterioration in the quality of cutting.

The purpose of the invention is to more precisely align the position of the fish relative to the plane of its symmetry and thereby increase the quality of its subsequent cutting.
