Abstract
Abstract To permit single-basket conveyor transport of textile cops from a supply bin holding a number of cops, without damage to the thread wound on the cops upon removal of an individual cop and introduction into the conveyor, the supply bin is constructed such that at least a portion of the bottom thereof is inclined forwardly towards a removal opening leading to the conveyor, and includes a movable base plate which is mounted for movement between a feed position in which the base plate is inclined towards the opening and a re-supply position in which the movable portion is inclined upwardly and away from the removal opening; an ejector is provided having a movable ejector element and occupying a space at least approximately the size of the geometric outline of a cop, the ejector element pushing against the cop and pushing the selected cop for removal through the removal opening against a spring-loaded flap, the ejector element, due to its size, blocking contact between the cop being ejected and a next adjacent cop, while permitting feeding a next following cop into removal position upon withdrawal of the ejector element, preferably downwardly and below the bottom of the inclined portion of the supply bin.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
298 words
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.
Claim 2
Dependent Claim
298 words
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.
Claim 3
Dependent Claim
24 words
Combination according to claim 1, wherein said ejector element (40) is pivotally mounted, and said movement between said three positions is a pivoting movement.
Claim 4
Dependent Claim
34 words
Combination according to claim 1, wherein a portion of the bottom of the supply bin located in advance of the removal opening is defined by a downwardly set off or stepped bottom portion (23).
Claim 5
Dependent Claim
89 words
Combination according to claim 1, wherein the ejector element (40) is formed with rakes or tines, said ejector element occupying the space (30) immediately in advance of the ejection opening (19) when the ejector element is in rest position, and the bottom of the supply bin (14) is formed with a grid or grate-like structure with the solid portions of the grate-like structure offset with respect to the solid portions of the rake structure of the ejector element to permit penetration of the ejector element through said grate structure.
Claim 6
Dependent Claim
68 words
Combination according to claim 1, wherein the ejector element is mounted for sequential movement through its positions in this sequence: re-supply position; rest position; feed position; the ejector, upon movement between between rest position and feed position closing off the space immediately in advance of the ejector opening to prevent pressure on the cop (7a) being ejected by the ejector caused by other cops located in the bin.
Claim 7
Dependent Claim
56 words
Combination according to claim 1, further comprising a blocking lever (50) located above the ejection opening (19) and extending into the bin structure (14), said blocking lever being movable between a position close to the ejection opening and a raised position to push cops in the vicinity of the ejection opening away from the ejection opening.
Claim 8
Dependent Claim
42 words
Combination according to claim 6, wherein the blocking lever is a plate-like element extending transversely of the bin and having a length approximately similar to that of a cop in the bin, said blocking lever plate (50) being mounted for pivotal movement.
Claim 9
Dependent Claim
