According to some embodiments, there is provided a welding device for welding outer peripheral edges of two irregular shaped plates which are overlapped, including: a rotary table to which the two irregular shaped plates in an overlapped state are fixed; a torch unit, including a welding torch positioned to face the outer peripheral edges of the two irregular shaped plates fixed to the rotary table; a first torch actuator, capable of changing an orientation and a distance of the welding torch relative to the outer peripheral edges; and a first controller, configured to control the first torch actuator, so that the orientation of the welding torch relative to a tangential line of the outer peripheral edges and the distance of the welding torch from the outer peripheral edges are kept constant along a circumferential direction of the outer peripheral edges, during rotation of the two irregular shaped plates.

Welding device and welding method

A welding device according to some embodiments includes a rotary table fixing two irregular shaped plates which are overlapped, a torch unit including a welding torch positioned to face outer peripheral edges of the two irregular shaped plates fixed to the rotary table, a torch actuator configured to move the welding torch toward and away from the outer peripheral edges, an after-shielding part mounted to the welding torch on downstream side in a rotational direction of the rotary table and having nozzles arranged along the rotational direction, configured to jet shielding gas to the outer peripheral edges, and including a first nozzle positioned upstream and a second nozzle positioned downstream of the first nozzle in the rotational direction, and a controller configured to control an orientation of the nozzle in a direction of decreasing a shielding-gas-jetting distance between the second nozzle and the outer peripheral edges welded by the welding torch.

Welding device

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

An automatic deboning method and apparatus are provided whereby, in a deboning process comprising the steps of: severing shoulder joints off from an upper half of a poultry carcass; stripping wings together with breast meat; then removing white meat, and thus deboning is completed, a high recovery rate is secured while coping with individuality of a work, such as a size and imbalance between the left and right sides, in an automatic manner, and the apparatus comprises: a main tact transport section 29 and an auxiliary tact transport section 30 wherein the main tact transport section 29 includes a main tact transport 20 and a group of 1.sup.st to 12.sup.th stations.
