Abstract:
A heat exchanging tube feed apparatus for a heat exchanger for taking out one by one a plurality of heat exchanging tubes each having a U-shape in outer appearance and arranged in parallel with each other and feeding the tubes in one direction, said heat exchanging tube feed apparatus comprising:push means for pushing out the heat exchanging tubes; a push-out cylinder for driving the push means; a grooved roller supporting one tube positioned to a lower side of the tubes from a lower side thereof; a link mechanism supporting the grooved roller; and cylinder means for driving the link mechanism vertically and horizontally and taking out sideways the tube supported by the grooved roller, wherein said grooved roller and said link mechanism are supported so as to be rotatable by a shaft at a tube take-out position, and when a U-shaped curved portion of the U-shaped tube passes at a time of tube insertion, the grooved roller and the link mechanism are opened so as to escape in a tube inserting direction through the shaft.
