  • Publication number: 20040163236
    Abstract: A heat exchanging tube assembling apparatus is adapted to a heat exchanger having an outer casing in which is arranged a partition plate formed with holes through which heat exchanging tubes, each having a U-shape in an outer appearance, are inserted from an open end side of the casing in a full automatic manner. The heat exchanging tube assembling apparatus comprises a tube grasping device for grasping a plurality of U-shaped tubes in a lump at a working position, a tube positioning device for positioning the grasped tubes to positions from which the U-shaped tubes are inserted into the holes formed to the partition plate, a tube taking-out device for sequentially taking out one by one the U-shaped tubes grasped by the tube grasping device, and a tube feed device for feeding the taken-out tubes toward the partition plate and inserting the tubes into the holes of the partition plate.

  • Patent number: 5946793
    Abstract: At a time of disassembling and assembling stator windings of a dynamo-electric machine in which the stator windings fitted in slots formed to an inner periphery of a stator core disposed inside a stator frame are disassembled therefrom and conveyed outside the stator core successively and new stator windings are then conveyed into the stator core and assembled into the slots successively, a mounting apparatus is arranged between the slot and an inside conveyer for mounting the stator winding into the slot. The stator winding is disassembled from the slot into which the stator winding is inserted while receiving and holding the stator winding by a receiving member provided for the mounting apparatus. The stator winding is then moved to the inside conveyer from the mounting apparatus and then conveyed from the inside conveyer to an outside conveyer.
