Abstract

In the manufacturing of ferrite core devices, an initial step can include threading a wire through a line of cores. Particularly when the cores are very small and the wire is very thin, so that manipulation of the parts is difficult, an automatic tool for this purpose is useful. Such a tool includes a feeder for segregating a row of torroidal cores from a randomly oriented supply and aligning the row for receipt of a wire.

Vibratory Feed for Ferrite Core Handling

In the manufacturing of ferrite core devices, an initial step can include threading a wire through a line of cores. Particularly when the cores are very small and the wire is very thin, so that manipulation of the parts is difficult, an automatic tool for this purpose is useful. Such a tool includes a feeder for segregating a row of torroidal cores from a randomly oriented supply and aligning the row for receipt of a wire.

Inclined block 10 is formed with grooves 12 for receiving cores 14 and guiding them as they roll by gravity to terminal position 16. At such position, cores 14 are held against further rolling by stop 18 mounted by block 10. Cover 20 prevents any cores 14 which are not aligned in grooves 12 from reaching position 16. The joint between block 10 and stop 18 is formed with a V-groove 22 for receiving wire 24 to be fed through aligned cores 16. The tops of walls 26 defining grooves 12 have inclined surfaces against which unoriented cores 30 rest. These cores 30 tend to slide down the block and jamb against cover 20. This is prevented by directional feed vibrator, not shown, which mounts block 10.

The vibrator provides a quick motion in direction 32, followed by a lower acceleration in direction 34. Cores 30 lying on their sides are fed in direction 36 by friction while cores 14, which are in position in grooves 12 to roll easily, are fed in direction 38 by gravity. Thus, the improperly oriented cores are urg...
