Abstract
Abstract A portable device for collecting and automatically sorting wound spools from open-end spinning machines is described. The device includes an entry chute that cooperates with the outlet end of a conveyor on the top of the spinning machine for guiding each spool into a wedge-shaped classifying guide, which directs each spool into an auxiliary storage magazine or onto a conveyor in accordance with the overall diameter of the spools. The spools directed to the conveyor are guided in the device onto a second conveyor, which moves in a horizontal path above a movable platform, from which extend a plurality of spool-receiving receptacles. Facilities are associated with the second conveyor for successively receiving classified spools from the first conveyor and for releasing the spools seriatim onto the underlying receptacles. When the spools are completely emptied from the spinning machine, the movable platform loaded with the collected spools can be taken out of the sorting device, while the rejected spools can be emptied from the auxiliary magazine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
261 words
In a portable arrangement for collecting and automatically sorting wound spools from an open-end spinning machine having an exit point for successively discharging the wound spools, the arrangement comprising, in combination, a main housing supported for movement past the exit point, an entry chute affixed to the housing for receiving the successive spools from the exit point, the entry chute having a lower guiding edge against which an outer periphery of each received spool bears during movement thereof to the outlet end of the entry chute, first conveying means supported in the housing, an auxiliary magazine supported in the housing, classifying means disposed opposite the outlet end of the entry chute for directing spools having a wound diameter less than a predetermined value to the auxiliary magazine and for directing the remaining spools onto the first conveying means, an auxiliary support floor movably carried in the housing, a plurality of spool-receiving receptacles extending upwardly in horizontally spaced relation from the auxiliary support floor in a prescribed regular pattern, second conveying means movably supported in the housing for horizontal movement in a first path extending successively past the upper ends of the receptacles, means interposed in the housing between the first and second conveying means for successively transferring spools from the first conveying means onto spaced points of the second conveying means, and means individually associated with the receptacles and disposed in the path of movement of the second conveying means for successively releasing spools carried on the spaced portions of the second conveying means onto successive ones of the underlying receptacles.

In a portable arrangement for collecting and automatically sorting wound spools from an open-end spinning machine having an exit point for successively discharging the wound spools, the arrangement comprising, in combination, a main housing supported for movement past the exit point, an entry chute affixed to the housing for receiving the successive spools from the exit point, the entry chute having a lower guiding edge against which an outer periphery of each received spool bears during movement thereof to the outlet end of the entry chute, first conveying means supported in the housing, an auxiliary magazine supported in the housing, classifying means disposed opposite the outlet end of the entry chute for directing spools having a wound diameter less than a predetermined value to the auxiliary magazine and for directing the remaining spools onto the first conveying means, an auxiliary support floor movably carried in the housing, a plurality of spool-receiving receptacles extending upwardly in horizontally spaced relation from the auxiliary support floor in a prescribed regular pattern, second conveying means movably supported in the housing for horizontal movement in a first path extending successively past the upper ends of the receptacles, means interposed in the housing between the first and second conveying means for successively transferring spools from the first conveying means onto spaced points of the second conveying means, and means individually associated with the receptacles and disposed in the path of movement of the second conveying means for successively releasing spools carried on the spaced portions of the second conveying means onto successive ones of the underlying receptacles.
Claim 3
Dependent Claim
43 words
An arrangement as defined in claim 1, in which the classifying means comprises wedge means having a vertex positioned opposite the outlet end of the entry chute, the wedge being positioned in transversely spaced relation to the guiding edge of the entry chute.
Claim 4
Dependent Claim
104 words
An arrangement as defined in claim 1, in which the first conveying means comprises, in combination, a first endless belt having a spool inlet point opposite the classifying means and a spool outlet point downstream thereof, blocking means disposed at the spool inlet point for normally inhibiting further passage of a spool, the blocking means being operable into a position out of the path of movement of the spool, sensing means normally actuable when the spool has reached the inlet point for operating the blocking means, and means rendered effective upon the occurrence of a predetermined condition for inhibiting actuation of the sensing means.
Claim 5
Dependent Claim
60 words
An arrangement as defined in claim 3, in which the transfer means comprises, in combination, third conveying means, and inertial means pivotally disposed at the inlet point of the first coveying means downstream of the blocking means and cooperable with an inlet point of the third conveying means for positioning spools passing the blocking means onto the third conveying means.
Claim 6
Dependent Claim
61 words
An arrangement as defined in claim 4, in which the transfer means further comprises, in combination, spool gripping means pivotally connected to spaced points along the second conveying means, and means rendered effective when the spool gripping means move past the outlet point of the third conveying means for engaging spools previously positioned at the inlet point by the inertial means.
Claim 7
Dependent Claim
77 words
An arrangement as defined in claim 5, in which the third conveying means has said outlet point disposed below and in alignment with the first path of the second conveying means, and in which the transfer means further comprises means disposed at the inlet point of the third conveying means for successively lifting spools conveyed to the inlet point of the third conveying means onto an overlying one of the spaced points of the second conveying means.
Claim 8
Dependent Claim
98 words
An arrangement as defined in claim 6, in which the second conveying means further comprises, in combination, a plurality of jaw means individually disposed at the spaced points along the second conveying means and cooperable with the lifting means, each jaw means being operable from a first normal spool-engaging position to a second spool-releasing position, and feeler means individually associated with each jaw means and engageable by the release means during movement of the second conveying means along the first path for operating the jaw means to discharge the engaged spool onto an underlying one of the receptacles.
Claim 9
Dependent Claim
60 words
An arrangement as defined in claim 7, in which the release means comprises a pivotally mounted arm normally disposed in a first position in the path of movement of the feeler means and responsive to engagement by the feeler means for movement into a second position out of the path of movement of a succeeding one of the feeler means.
Claim 10
Dependent Claim
61 words
An arrangement as defined in claim 8, in which the second conveying means further comprises, in combination, jaw resetting means including lever means disposed behind each feeler means and operable into an active position engageable with the pivotally mounted arm of the release means when such arm is in the second position for moving such arm back into its first position.
Claim 11
Dependent Claim
25 words
An arrangement as defined in claim 9, in which the second conveying means further comprises means for operating the lever means into its active position.
