Title: Singulating device for vibrating yarn package feeder - has adjustable flexible exit passage walls to allow passage width to be altered to suit yarn package size
Inventor: BUEHREN HEINZ
IPC: B65G47/14
Filed: 1991-04-16
Abstract: Singulator is driven by a vibrator (28) and has a circular feed bowl with a domed centre (2) and a spiral feed passage (3). A device (7) for adjusting the width of the feed passage extends over 90 degrees of the feed bowl, ending at the delivery point (11). The device does not give sharp changes in section in the feed passage. The device can be a flexible wall whose length is adjusted tangentially to give a radial movement. An additional guide (10) can be positioned on the inside of the feed passage. Yarn packages are pref. placed randomly into the domed centre (2) of the feed bowl and travel under vibration towards the periphery. They enter the spiral feed passage (3) and gradually move towards the exit (11). A guide (20) and passage walls (7, 10) ensure that they emerge singly and axially aligned. The width of the exit section is accurately adjusted by moving the flexible wall (7) to suit the yarn package size which is being handled. USE/ADVANTAGE - When used in a vibrating feeder for a winding machine, the singulator provides adjustment which avoids the need to change feed bowls for different package sizes.
