A cutting apparatus cuts a string in a workpiece by bringing a cutter into contact with the workpiece while rotating the workpiece supported by a clamper. The workpiece supported by the clamper is restrained by a holding member from the opposite side from the cutter. The holding member is elastically supported by a support part.

Cutting apparatus

A work measurement device according to an aspect includes a posture holding surface for holding a posture of a work, a first work presser capable of pressing the work against the posture holding surface from an opposite side to the posture holding surface across the work, a contact disposed to be able to contact the work, a moving unit for moving, relative to the contact, the work pressed against the posture holding surface by the first work presser. The contact is configured to contact the work downstream of the first work presser in a relative movement direction of the work by the moving unit.

Work measurement device and slit forming system

A slit forming device according to an aspect includes a damper configured to pass through a plurality of stations arranged on a circumference, a slit forming blade disposed on an outer circumference side or an inner circumference side of a slit forming station among the plurality of stations, and a damper rotating part capable of rotating the damper about a vertical line such that a slit forming surface of a work faces the slit forming blade in the slit forming station.

Slit forming device

A cartilage cutting device for a bone-in meat according to an embodiment includes a cutting blade disposed on a conveying path for a bone-in meat and an elastic support portion for elastically supporting the cutting blade so that the cutting blade can recede by a reaction force applied to the cutting blade when cutting the bone-in meat. The elastic support portion is configured such that an elastic supporting force of the elastic support portion is switchable between a first elastic supporting force and a second elastic supporting force. The first elastic supporting force is capable of cutting a cartilage adhering to a bone part of the bone-in meat. The second elastic supporting force is smaller than the first elastic supporting force and is incapable of cutting the cartilage.

A processing system for bone-in limb meats according to an embodiment includes: a right-limb incision-forming portion for forming incision on a right bone-in limb meat; a left-limb incision-forming portion for forming incision on a left bone-in limb meat; a processing line including a plurality of processing stations to separate a bone part and a meat part of each bone-in limb meat on which incision is formed at the right-limb incision-forming portion or the left-limb incision-forming portion; and a loading portion arranged at an uppermost stream part of the processing line to receive the right bone-in limb meat with incision formed at the right-limb incision-forming portion and the left bone-in limb meat with incision formed at the left-limb incision-forming portion.

Processing system for bone-in limb meats and producing method for deboned meats

A bone-meat separation device for a bone-in limb meat according to an embodiment is a bone-meat separation device for a bone-in limb meat for separating a meat part adhering to a trunk-side end bone head of a bone-in limb meat, the device including a plurality of clamp portions for conveying the bone-in limb meat along a conveying path, a guide portion disposed on the conveying path and forming a V-shaped guide space with an open end thereof being directed upstream in a conveying direction of the bone-in limb meat, a cutter disposed at a downstream end of the guide space in the conveying direction, and a holding portion holding the meat part below the guide portion and the cutter. The holding portion is configured to hold the meat part of the bone-in limb meat when the meat part is cut from the trunk-side end bone head with the cutter.

In a deboning process, a knee joint length is measured in a work loading section of a first process station, and incision making of a thigh meat portion is performed in a second process station based on the measured knee joint length. At the same time, the entire length of a work is measured, and the knee joint length is calculated from previously collected data based on the measured entire length of the work. Positioning of a cutting blade and a meat separator is performed based on these values in subsequent process stations, and cutting of a tendon adhering to a knee joint and tearing of thigh meat are performed. A thigh bone is separated from a lower thigh in a further process station.

Device and method for deboning bone-in leg

In an automated deboning device for deboning a bone-in leg of livestock carcass, a clamp unitsuspending the work w includes a servomotor, a threaded shaftconnected to an output shaft of the servomotorand a lifting and lowering blockthreadably mounted on the threaded shaft. A lifting and lowering rollermounted on a lifting and lowering shafttravels in a traveling pathto lower and transfer the work w to a next work station. By bring a swinging rollermounted on the lifting and lowering shaftin contact with the cam plate, the lifting and lowering shaftis rotated by a setting angle so that the work w faces round cutter blades. Thus, the pathway of the round cutter bladescan be approximately straight, thereby simplifying and reducing the cost of the moving mechanism.

Method and device for deboning bone-in leg

A method and an apparatus for separating thigh meat and oyster meat from the thighbone can automatically separate thigh meat and oyster meat without detecting the boundary of the white cap at an end of the thighbone and the meat including thigh meat and oyster meat. The apparatus includes a cutter that is inserted into the detected boundary part in the final operation of deboning a thigh-with-bone of an edible beast and bird. The apparatus has a clamper, a guide-with-a-groove device, and a guide-with-a-cutter device downstream of the guide-with-a-groove device provided on the transfer line of the clamper. Both guide devices are provided such that the open end side of each guide device, which is Y-shaped is directed toward upstream of transfer of the clamper.

Apparatus for separating thigh meat and oyster meat

A method and apparatus are provided for separating thigh meat and oyster meat from the thighbone automatically without detecting the boundary of the white cap at an end of the thigh bone and the meat including thigh meat and oyster meat and inserting a cutter into the detected boundary part in the final operation of deboning a thigh-with-bone of an edible beast and bird. The apparatus of the invention for separating thigh meat and oyster meat is composed of a clamper, a Y-shaped guide-with-a-groove, and a Y-shaped guide-with-a-cutterdownstream of the guideprovided on the transfer line of the clamper, both guides being provided such that the open end side of Y-shape of each guide is directed toward upstream of transfer of the clamper.
