Patent

CA 2425248

Methods and apparatus are described for automatically splitting carcass (10) of a slaughtered animal. The apparatus includes saw assembly (17) mounted on carriage (22) and ultrasonic scanner (30). Assembly (17) is moved by carriage (22) along support (16) so that saw blade (18) commences cutting at the base of the spine and progressively advances downwardly following the line of the spine. Scanner (30) scans carcass (10) and the data signals are processed to locate the spine and/or determine its conformation immediately ahead of the point where blade (18) is splitting carcass (10). The processed signals are used to control the degrees of movement of blade (18) including lateral movement, rolling movement, vertical movement, tilting movement and yawing movement. The apparatus can also follow a desired line of cut in other medical, veterinary or forensic applications, or for cutting manufactured products, artefacts or achaeological articles having an internal structure.

L'invention concerne des procédés et des appareils de découpe automatique de carcasses (10) d'animaux abattus. Cet appareil comprend un ensemble scie (17) monté sur un chariot (22), et un échographe (30). L'ensemble (17) est entraîné par le chariot (22) le long d'un support (16) de sorte que la lame de scie (18) commence à découper la carcasse depuis la base de la colonne vertébrale et avance progressivement vers le bas, en suivant le prolongement de la colonne vertébrale. Un échographe (30) analyse la carcasse (10). Les signaux de données sont traités pour situer la colonne vertébrale et/ou déterminer sa conformité immédiatement devant le point où la lame (18) découpe la carcasse (10). Les signaux traités sont utilisés pour contrôler le degré de déplacement de la lame (18), notamment le déplacement latéral, le déplacement de roulement, le déplacement vertical, le déplacement d'inclinaison et le mouvement de lacet. Cet appareil peut également suivre l'axe de coupe souhaité dans d'autres applications médicales, vétérinaires ou médico-légales, ou pour découper des produits manufacturés, des artefacts ou des objets archéologiques pourvus d'une structure interne.
