Opfindelsen angår en fremgangsmåde til afskæring af en kropsdel fra slagtet fjerkræ ved hjælp af et med en skærende æg forsynet skæreelement/ som samvirker med en dermed forbunden positioneringsdel, der bevæges og er indrettet til positioneis ring af det ønskede skærested i forhold til den skærende æg.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of cutting a body part from slaughtered poultry by means of a cutting element provided with a cutting egg which cooperates with an associated positioning part which is moved and arranged for positioning the desired cutting point relative to the cutting egg.

Kropsdele, såsom ben, vinger og hals, på slagtet fjerkræ afskæres normalt ved hjælp af en eller flere stationære, ofte roterende skærende knive, langs med hvilke de dele, som skal afskæres, passerer. Dette kræver en meget nøjagtig positionering af delene i forhold til det skærende element.Body parts, such as legs, wings and throats, of slaughtered poultry are usually cut by one or more stationary, often rotating cutting blades along which the parts to be cut pass. This requires a very accurate positioning of the parts relative to the cutting element.

Denne positionering tilvejebringes ikke altid lige godt, hvilket giver problemer, især når fugle med forskellig størrel-15 se skal bearbejdes. Yderligere er det svært at positionere visse dele, f.eks. overgangen mellem vingen og kroppen, i forhold til en stationær roterende skærende kniv.This positioning is not always provided well, which causes problems, especially when birds of different sizes need to be processed. Further, it is difficult to position certain parts, e.g. the transition between the wing and the body, relative to a stationary rotary cutting knife.

Fra U.S. patent nr. 2.926.383 kendes et apparat til overskæring af halsen på slagtet fjerkræ, som af en transportør føres fremad ophængt med hovedet nedad. Apparatet har et fast V-formet styreorgan, som er dannet af en V-formet udskæring i en vandret anbragt plade, og hvis kanter er affasede ^ til dannelse af skærende ægge. En aflang roterende kniv med to aktive skærende ægge er anbragt til at rotere om en lodret akse og samvirkende med den V-formede udskærings skærende ægge at overskære fjerkræhalsen, når denne er blevet ført ind i udskæringen. Positionerings- eller styreorganet og skæreorganet udgøres således af to separate dele, at hvilke 30 positioneringsorganet står stille, medens skæreorganet bevæges.From the U.S. Patent No. 2,926,383 discloses an apparatus for cutting the throat of slaughtered poultry which is carried forward by a carrier suspended with its head down. The apparatus has a fixed V-shaped guide member formed by a V-shaped cutout in a horizontally arranged plate, the edges of which are beveled to form cutting edges. An oblong rotating knife with two active cutting edges is arranged to rotate about a vertical axis and cooperating with the V-shaped cutting edge to cut the poultry neck once it has been inserted into the cut. The positioning or control means and the cutting means are thus formed by two separate parts, which position the positioning means while the cutting means is moved.

Fra U.S. patent nr. 4.091.503 kendes en fremgangsmåde og et apparat af den indledningsvis nævnte art. Ved denne fremgangsmåde til at brække, strække og dernæst overskære halsen 35 af slagtet fjerkræ fremføres fuglene ophængt i fødderne, hvorefter halsen gribes af en til apparatet hørende positioneringsdel og dernæst strækkes og afskæres. Denne fremgangsmådeFrom the U.S. U.S. Patent No. 4,091,503 discloses a method and apparatus of the kind mentioned above. In this method of breaking, stretching and then cutting the throat 35 of slaughtered poultry, the birds are advanced suspended in the feet, after which the neck is gripped by a positioning part of the apparatus and then stretched and cut. This procedure

Det fra U.S. patent nr. 4.091.503 kendte apparat er kompliceret og dyrt. Det omfatter to separate, indbyrdes forbundne roterbare dele, hvoraf den første er forsynet med positioneringsdele, der er anbragt langs dets periferi, og den anden er forsynet med skæreelementer, der har radialt forløbende skæreægge. Denne opbygning sikrer imidlertid ikke, at overskæringen foretages på det ønskede sted.That from the U.S. Patent No. 4,091,503 known apparatus is complicated and expensive. It comprises two separate interconnected rotatable portions, the first of which is provided with positioning portions disposed along its periphery and the second of which is provided with cutting elements having radially extending cutting edges. However, this structure does not ensure that the cutting is done at the desired location.

Formålet med opfindelsen er at anvise en fremgangsmåde og •,g et apparat til udøvelse af fremgangsmåden, og ved hjælp af hvilke de nævnte ulemper er overvundet.The object of the invention is to provide a method and apparatus for practicing the method and by which the disadvantages mentioned are overcome.

Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at positioneringsdelen er direkte forbundet med skæreelementet 2g og således bevæges efter i det væsentlige samme bane som dette. Herved fremkommer en særlig simpel fremgangsmåde, idet positioneringen af overskæringsstedet og overskæringen foretages i det væsentlige samtidigt af de to direkte indbyrdes forbunde dele.The method according to the invention is characterized in that the positioning part is directly connected to the cutting element 2g and thus moves along substantially the same path as this. This results in a particularly simple method, the positioning of the intersection site and the intersection being carried out substantially simultaneously by the two directly interconnected parts.
