Abstract
A novel structure of a spiral conveyor is provided which is also suitable for conveyance of curl-shape and permanent-shape cuttings in a lathe system while suppressing the occurrence of noise caused by vibration. At the lowest point, a conveyance spiral of this spiral conveyor for conveying chips contacts the ground (the ground point P) at the lowest point of a tray, and the conveyance spiral is not in contact with a pair of rails in opposite positions on the inner surface of the tray and extending in the length direction, and small gaps t are formed between the conveyance spiral and the rails. Because it is only at the lowest point that the conveyance spiral contacts the tray, similarly to conventional rail-less designs, a low level of noise is achieved, similar to that in the rail-less designs.
