SPIRAL SYSTEM STORAGE AND TRANSPORTATION DEVICE

摘要

A storage and conveying unit having two helically shaped guideways on which workpieces are adapted to be supported in a position inclined slightly to the vertical. One of the guideways is mounted on an outer cylindrical support and the other guideway is mounted on an inner cylindrical support having a diameter slightly less than the diameter of the outer cylindrical support. The inner cylindrical support is reciprocated vertically through a short stroke to advance the workpieces in the direction of their inclination. The two cylindrical supports are provided with vertical guides and guide rollers engaging the guides for preventing relative circumferential movement between the two supports.
