Abstract
A heat exchanger tube inserting apparatus includes a roller conveyor section and a pushing section. The roller conveyor section includes a roller that advances the heat exchanger tube to thereby insert the heat exchanger tube into the insertion holes of the fins and to a first position by rotation of the roller. The pushing section pushes the heat exchanger tube, which has been moved to the first position by the roller conveyor section, to a second position located further inside than the first position.
Claims22
A heat exchanger tube inserting apparatus adapted to insert, in a process of assembling a heat exchanger including a number of fins and heat exchanger tubes passing through the number of fins, a heat exchanger tube into insertion holes formed in the fins, the heat exchanger tube inserting apparatus comprising:
- a roller conveyor section including a roller configured to advance the heat exchanger tube in an insertion direction to thereby insert the heat exchanger tube into the insertion holes of the fins and to a first position by rotation of the roller;
- a pushing section configured to push the heat exchanger tube, which has been moved to the first position by the roller conveyor section along the insertion direction, to a second position located further inside than the first position;
- and
- a main body frame supporting the roller conveyor section and the pushing section,
- the roller conveyor section and the pushing section being spaced from each other along a direction horizontally transverse to the insertion direction to allow simultaneous insertion of a tube into the first position and another tube into the second position, and
- the main body being movable parallel to the extending direction of the fins.
A heat exchanger tube inserting apparatus adapted to insert, in a process of assembling a heat exchanger including a number of fins and heat exchanger tubes passing through the number of fins, a heat exchanger tube into insertion holes formed in the fins, the heat exchanger tube inserting apparatus comprising:
- a roller conveyor section including a first roller and a second roller configured to advance the heat exchanger tube to thereby insert the heat exchanger tube into the insertion holes of the fins and to a first position by rotation of the first roller and the second roller;
- and
- a pushing section configured to push the heat exchanger tube, which has been moved to the first position by the roller conveyor section, to a second position located further inside than the first position,
- the heat exchanger tube being a hairpin tube including a pair of straight tube portions extending in parallel to each other and a hairpin portion connecting respective ends of the straight tube portions,
- the first roller
- coming into contact with the pair of straight tube portions in a case when the pair of straight tube portions are in a horizontal state of extending horizontally side by side, and
- coming into contact with one of the pair of straight tube portions that is at a lower position in a case when the pair of straight tube portions are in an oblique state of extending side by side at different vertical positions, and
- the second roller coming into contact with the other of the pair of straight tube portions that is at a higher position in the case when the pair of straight portions are in the oblique state.
