Abstract:
A heat exchanging tube feed apparatus for a heat exchanger for feeding out a heat exchanging tube, received at a predetermined position, in one direction, comprising:a base; a pair of roller support frames supported by the base for being movable symmetrically upward and downward; an introduction mechanism for moving the tube with respect to the roller support frames, the introduction mechanism having a pair of guide rollers supported by the roller support frames, respectively; and a plurality of drive rollers and follower rollers which are disposed on a downstream side of tube insertion direction of the introduction mechanism, wherein the guide rollers receive extreme ends of the tube through a reciprocal motion of the roller support frames along the tube insertion direction, the drive rollers and the follower rollers are rotatable so as to clamp the tube to thereby feed the tube to the heat exchanger.
