Definitions

  • the present invention relates to a method, a device and a system for processing at least a back end part of an animal carcase, as well as a system for primary cutting and further subsequent processing of a carcase.
  • the processing in particular comprises fixed gripping or retaining of the back end part and possible further processing.
  • the carcase can for example be a hog, cattle or sheep carcase having a heel joint constituting a thickening relatively to a ham or a hind toe part, extending in separate directions from the heel joint.
  • slaughterhouses pose increasing demands of automatic and individual processing of parts of a carcase in order to obtain optimal yield with minimal costs.
  • carcases are often conveyed hanging vertically from hooks along an overhead conveyor.
  • the hooks may, e.g., be gambrels or hooks according to German standard DIN 5047, also known as "Euro Haken".
  • the carcases can either be conveyed as carcase sides or as complete carcases.
  • the carcases are conveyed in single file or in pairs to a primary cutting system, where the carcase sides are divided into front end parts, middle parts and back end parts, and from the primary cutting system they are conveyed lying on conveyor belts for further processing in the processing line.
  • Subsequent processing of the parts may be of various kind, and the slaughterhouses normally also desire the possibility of individually processing the parts.
  • a back end part is conveyed further on in the processing line with or without hind toe, loop tying, i.e. with a string through the hind leg, or it may be desired that the back end part is conveyed further on, lying on a conveyor belt, or that the part is transferred to a vertical position to a conveyor system where the parts are conveyed vertically hanging or suspended from, e.g., a string.
  • the back end parts may be conveyed hanging vertically separately or in batches on vertical rods with hook, i.e. on so-called "Christmas trees".
  • the processes mentioned above are performed at different times relatively to the primary cutting of the carcase.
  • cutting the hind toe away from the back end part may be performed automatically in connection with putting down of the carcases from a vertically hanging transport to a horizontally lying transport, or manually after putting down the carcases to the horizontally lying transport.
  • Loop tying the parts and/or hanging the parts on Christmas trees is performed manually or semi-automatically after the parts have been conveyed away from the primary cutting system.
  • DK 174515 describes a system for processing carcase sides, where a carcase side is conveyed suspended from its hind toe in a gambrel.
  • the hind toe is automatically cut off after a gripping mechanism has gripped between the knee joint and the heel joint and lifted the hind toe and the ham out of the gambrel, in such a way that the ham of the carcase side is suspended in the gripping mechanism.
  • the ham falls upon a conveyor belt by means of which the carcase side may be conveyed to a position of primary cutting.
  • EP 1 053 684 discloses an automatic machine for deboning animal parts by means of a fluid jet.
  • Hams with the hind toe and heel joint already cut off are conveyed to a pick-up station where the end of the shin bone is engaged by a gripper which grips and retains the ham.
  • the gripper then moves the ham to a deboning station where the deboning takes place.
  • the orientation of the ham is changed from a substantially horizontal orientation to a substantially vertical orientation. Since the hind toe and heel joint have already been cut off, it is not possible to let the gripping means rest on the heel joint during this movement. Accordingly, relatively strong gripping forces are needed in order to retain the ham.
  • a method and a device for processing preferably including at least positioning and fixation of at least a back end part of a carcase having a thickened heel joint and a hind toe part extending from a first side of the heel joint, and a ham part extending from a second side of the heel joint, said second side being opposite to the first side.
  • the method according to the invention is characterised in that the back end part in a lying position is gripped by means of a gripping and retaining mechanism at the ham side of the thickened heel joint. Thereby fixated gripping of back end parts, e.g. lying horizontally on a conveyor belt, is obtained.
  • the parts may subsequently be processed in various manners. They may, e.g., be transferred to a hanging position for cutting off the hind toe, loop tying or another further processing.
  • a lying back end part is gripped around the hind leg, e.g. immediately subsequently to cutting off the back end part in the primary cutting system.
  • the gripping and retaining mechanism which may have a closed and an open mode, may follow the back end part synchronously, and rotate it from a first to a second orientation, e.g. from a substantially horizontal to a substantially vertical orientation. The further processing will normally take place in the second, e.g. vertical, orientation.
  • the position and/or the orientation of the back end part may be detected using suitable means, e.g. a vision system, or the position/orientation may be transferred from the control system of the primary cutting system, thereby allowing gripping of the back end part in a predefined position, e.g. around the hind leg above the thickened heel joint.
  • suitable means e.g. a vision system
  • the position/orientation may be transferred from the control system of the primary cutting system, thereby allowing gripping of the back end part in a predefined position, e.g. around the hind leg above the thickened heel joint.
  • the thickened heel joint will engage an upper side of the gripping and retaining mechanism, thereby retaining and fixating the part relatively to the thickened heel joint. This fixation is appropriate for the further processing, since the thickened heel joint may serve as an anatomical reference for, e.g., cutting off the hind toe or loop tying.
  • a weighting unit may form part of the system according to the invention. Thereby the weight of the individual back end part, or other parts of the carcase, may be determined, and may be included for the purpose of controlling the further processing of the back end part.
  • the gripping and retaining mechanism may be arranged at the end of a gripping arm which is rotatable about a first axis at one end of the gripping arm, the gripping and retaining mechanism being arranged at the other end of the gripping arm.
  • further gripping arms are provided, e.g. 2, 3, 4 or more, the number being chosen in accordance with the desired capacity of the system.
  • the rotation of the gripping arm about the first axis may advantageously be synchronized with the movement of a conveyor belt on which the back end part is conveyed.
  • the first axis is at least substantially parallel to the conveyor belt, and at least substantially perpendicular to the conveying direction of the back end part on the conveyor belt.
  • the gripping and retaining mechanism may further be rotatable about a second axis arranged at least substantially parallel to the gripping arm.
  • the rotation about the second axis may be provided by an actuator mounted on the gripping arm.
  • the gripping and retaining mechanism may grip a back end part about the hind leg above the heel joint, and the gripping arm with the retained back end part may subsequently be rotated about the first axis, in such a way that the peripheral velocity of this movement corresponds to the conveying velocity of the lying back end part.
  • the length of the gripping arm and the position where the gripping takes place may be determined in such a way that the back end part by rotation is moved over an end of the conveyor belt, and in such a way that the back end part is rotated about the second axis, due to the force of gravity, to a vertically hanging position.
  • the rotation of the gripping arm with the rotated gripping and retaining mechanism with the retained back end part may be stopped in a given position, in such a way that the back end part is hanging vertically, carried by the gripping mechanism with the upper side of the heel joint of the hind leg resting on the upper side of the gripping and retaining mechanism.
  • Subsequent processing may be performed with the back end part positioned in this known position and with the defined position of the heel joint of the hind leg by activating one or more processing units. For example, a hind toe cutting unit, a loop tying unit, or a transfer/hanging unit may be applied.
  • the gripping and retaining mechanism may be opened, thereby releasing the back end part from the system. Subsequently the gripping and retaining mechanism is rotated back to its initial position relatively to the gripping arm, and the gripping arm with the gripping mechanism may be rotated in such a way that the next back end part may be processed.
  • the system may be provided with several processing units which may be automatically activated depending on the desired processing.
  • the gripping means may be provided with a weighting cell, in such a way that a vertically hanging back end part may be weighted, and in such a way that the weight may be taken into account when deciding the further processing of the back end part.
  • the invention further relates to a system for processing at least a back end part of a carcase, the system comprising a device as described above and a processing unit.
  • the invention relates to a system for primary cutting and further processing of a carcase, the system comprising:
  • a primary cutting system comprising control means for controlling the primary cutting
  • control means for controlling the further processing performed by the system comprising control means for controlling the further processing performed by the system; wherein the control means of the primary cutting system can communicate with or is integral with the control means for controlling the further processing.
  • Fig. 1 shows the system with four gripping arms with gripping mechanisms in a closed position
  • Fig. 2 shows the system with four gripping arms with a back end part hanging vertically.
  • Fig. 1 shows a system with four gripping arms 1 with gripping and retaining mechanism 2 having gripping units or jaws 3 and 4, at least one of the jaws 3, 4 being adapted to be activated by actuator 5.
  • the gripping arm(s) 1 is/are rotatable about an axis arranged in parallel with conveyor belt 8 and perpendicularly to the conveying direction 11 with centre of rotation 6.
  • the gripping and retaining mechanism 2 can rotate in rotational bearing 7 about an axis arranged in parallel with gripping arm 1.
  • Fig. 2 shows the system with a vertically hanging back end part 9.
  • Gripping arm 1 has been rotated about centre 6 after gripping of back end part 9 on conveyor belt 8 by gripping mechanism 2.
  • gripping mechanism 2 has been rotated in rotational bearing 7 due to the gravitational force acting on back end part 9.
  • the vertically hanging back end part 9 is hanging with the upper side of its heel joint resting on the upper side of the closed gripping units 3 and 4, and cutting off the hind toe may be performed at a desired incision angle and decision position in the heel joint by cutting means 10, since the cutting means 10 may be angled, and/or moved horizontally and vertically.
