Abstract
A knife assembly for performing, for example, a filleting cut on a slaughtered and gutted fish has at least one cutting head. The cutting head has at least one housing with a knife unit and a drive unit for rotationally driving a knife shaft rotatably borne inside the housing. A separating knife is arranged on a free end of the knife shaft for conjoint rotation. The knife shaft is axially movable relative to the housing and is configured to be decouplable from the drive unit for the purpose of axially moving the knife shaft in such a way that rotational movement of the knife shaft can be performed independently of the axial movement of the knife shaft. An apparatus and a method are disclosed.
Claims32
A knife assembly for performing a filleting cut on a slaughtered, beheaded and at least partly gutted fish, comprising:
- at least one cutting head, the cutting head comprising;
- at least one housing having a knife unit;
- a drive unit configured and adapted for rotationally driving a knife shaft rotatably borne inside the housing;
- a separating knife arranged on a free end of the knife shaft for conjoint rotation;
- wherein the knife shaft is axially movable relative to the housing and is configured to be decouplable from the drive unit for the purpose of axially moving the knife shaft in such a way that rotational movement of the knife shaft can be performed independently of the axial movement of the knife shaft.
A method for filleting animal products, comprising the steps of:
- feeding the animal product that is to be processed to at least one working station by a transport device in a transport direction;
- performing a processing cut on the animal product being processed, using a knife assembly as a working station, by transporting the animal product being processed along at least one rotationally driven separating knife of a cutting head of the knife assembly;
- the rotating separating knife being axially moved out of a standby position into a cutting position and back again or vice versa in order to be positioned in relation to the animal product being processed;
- wherein axial adjustment of the separating knife is superimposed on the rotational movement of the separating knife by only a knife shaft carrying the separating knife being moved relative to a housing of the cutting head of the knife assembly.
