Supply bin and feeder system combination for textile cops or pirns

The combination of a supply bin (14) for textile cops and a feeder system to feed the cops, singly, to a removal station (24), and to separate the cops during the feeding operation to prevent pressure by cops in the supply bin on a cop (7a) being removed for feeding, having

• a bin structure having a removal opening (19) formed therein;
• a biassed flap (26) releasably closing the removal opening,
• and ejection means (40) engageable with the lowermost cop to feed the cop to the removal means,
• wherein, in accordance with the invention,
• at least a portion of the bottom of the supply bin structure (14) is inclined forwardly towards the removal opening (19) and includes
• a movable base plate (31), the base plate being mounted for movement between a feed position in which the base plate is inclined in the direction of inclination of the bottom of the supply bin and towards the opening, and a re-supply position in which the base plate is inclined upwardly and away from the removal opening (19);
• and the ejection means comprises
• a movable ejector (40) occupying a space at least approximately of the size of the geometric outline of a cop, said ejector element (40) being mounted for movement between a rest position in which the ejector element is located immediately in advance of the cop removal opening (19) and closes off said opening, a re-supply position in which the ejector element (40) is located in a position beneath the bottom of the supply bin (14), and a feed position in which the ejector (40) is engaging a cop (7a) to feed said cop in advance thereof, along the downwardly inclined bottom of the supply bin and pushing said cop against said biassed flap (26) and through said removal opening.
