Abstract:
1. A method for deboning a bone-in leg by a deboning device, the method comprising the steps of: clamping the bone-in leg at an ankle thereof by a clamp unit; transferring the clamp unit intermittently between a plurality of work stations; and performing in each of the work stations at least one of an incision-making process of making an incision on the bone-in leg longitudinally by moving a cutter blade along the bones and a meat-separating process of separating a meat part of the bone-in leg from the bones by lifting the bone-in leg relatively upward while holding down the meat part from above by a meat separator and cutting a tendon with a cutter blade, wherein the deboning device comprises: a lifting and lowering shaft whose lower end is attached to the clamp unit and which has a lifting and lowering roller above the clamp unit; an elevating unit which is provided in each of the work stations and comprises a drive motor, a threaded shaft connected to an output shaft of the drive motor and a lifting and lowering table threadably mounted on the threaded shaft; and a traveling path which is arranged between the work stations and slopes downward in a transferring direction of the clamp unit, wherein the incision-making process or the meat-separating process is performed at one of the plurality of working stations by placing the lifting and lowering roller on the lifting and lowering table and lifting the bone-in leg by lifting the lifting and lowering table, and wherein the lifting and lowering roller travels in the traveling path under weight of the bone-in leg to transfer the clamp unit downward from one work station to a subsequent work station.
