Abstract: 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.

Abstract: 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.

Abstract: In an automated deboning device for deboning a bone-in leg of livestock carcass, a clamp unit 12 suspending the work w includes a servomotor 104, a threaded shaft 106 connected to an output shaft of the servomotor 104 and a lifting and lowering block 108 threadably mounted on the threaded shaft 106. A lifting and lowering roller 92 mounted on a lifting and lowering shaft 70 travels in a traveling path 94 to lower and transfer the work w to a next work station. By bring a swinging roller 84 mounted on the lifting and lowering shaft 70 in contact with the cam plate 170, 180, 182, the lifting and lowering shaft 70 is rotated by a setting angle so that the work w faces round cutter blades 22, 64. Thus, the pathway of the round cutter blades 22, 64 can be approximately straight, thereby simplifying and reducing the cost of the moving mechanism.
