ABSTRACT:
A delivery device for delivering articles to be heated within a compound furnace, including at least two furnace chambers differing in heating conditions and which can effectively prevent damage to the articles by melt adhesion due to contact with each other and which can also reduce the adverse influence of high temperatures upon the component members of the delivery device is disclosed as including clamps which are capable of reciprocating within a delivery passage and which have the function of clamping and unclamping the articles to be heated so as to deliver or transport the same. Running rods, upon which the clamps are fixed, are adapted to move along the delivery passage and a main drive source for driving the rods and clamps, as well as a subsidiary drive source for performing the clamping and unclamping operations of the clamps are also provided. A movement converting transmission mechanism for converting the linear driving force of the subsidiary drive source into a rotary drive force for rotating the running rods in order to actuate the clamps for performance of the clamping and unclamping operations is included and a clamp positioning mechanism for determining the stopping position of the clamps is operatively associated with the running rods. The movement converting transmission mechanism may include a rack-and-pinion mechanism, a slide bar or rod-crank mechanism, an actuator-gear mechanism, or a cylindrical cam mechanism.
