Abstract
A spiral parts heat treatment apparatus includes a first guide, a transfer unit, a second guide, and a controller. The first guide has a carrier portion that continuously conveys the manufactured spiral parts carried thereon in a longitudinal direction. The transfer unit is disposed downstream from the first guide to feed the spiral parts one by one after discrimination. The second guide is provided continuously to the transfer unit and has a carrier portion and a driving portion. The carrier portion serves to guide the spiral parts carried thereon in the longitudinal direction in the heat treatment furnace. The driving portion serves to push the spiral parts from a rear end side thereof and a driving portion. The controller performs a control operation so as to feed the spiral parts one by one.
