Abstract
Abstract An apparatus for arranging cross-wound packages, wound on a spinning machine, upon an auxiliary transport belt which is aligned with a main transport belt extending longitudinally of the spinning machine and serving for carrying away the cross-wound packages. One end of the auxiliary transport belt adjoins one neighboring confronting end of the main transport belt. A detector is actuated by the cross-wound packages moved by the transport belt and initiates starting of the auxiliary transport belt upon the arrival of a cross-wound package. Also, there is provided a stopping device for the auxiliary transport belt, whereby the latter is stopped after it has moved through a distance at least approximately equal to the bobbin length. The currently known continuous sliding of the transport belt under the full cross-wound packages is thus avoided. There is also avoided that the thread layers of the cross-wound packages entangle with one another or come to lie at the end faces of the cross-wound packages which would severely impede unwinding thereof or even make such unwinding impossible.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
300 words
An apparatus for removing cross-wound packages having a predetermined bobbin length from a spinning machine, and comprising: a main transport belt extending substantially lengthwise of the spinning machine for receiving cross-wound packages therefrom and serving to deliver said cross-wound packages to one end of a transport path defined by said main transport belt; each of said cross-wound packages having a lengthwise axis extending substantially parallel to their direction of movement during transport upon said main transport belt; an auxiliary transport belt positioned substantially in alignment with said main transport belt and defining a transport path having a starting end adjoining said one end of said transport path of said main transport belt; means for limiting to an acceptable minimum, during the removal of said cross-wound packages from said spinning machine, any relative sliding movement between said auxiliary transport belt and said cross-wound packages; said limiting means comprising detector means for controlling the movement of said auxiliary transport belt; said detector means being arranged at a region where said transport path of said auxiliary transport belt neighbors said transport path of said main transport belt; said detector means being activated by said cross-wound packages on said transport belts in order to initiate movement of said auxiliary transport belt whenever one of said cross-wound packages passes said detector means; said limiting means further comprising stopping means for stopping said auxiliary transport belt after movement of the same through a distance at least approximately equal to the bobbin length of said cross-wound packages such that a successive arrangement of a closely spaced predetermined number of said cross-wound packages can be formed on said auxiliary transport belt; and said limiting means still further comprising removal means for removing in substantially frictionless manner at least one of said cross-wound packages from said auxiliary transport belt.
Claim 2
Independent Claim
300 words
An apparatus for removing cross-wound packages having a predetermined bobbin length from a spinning machine, and comprising: a main transport belt extending substantially lengthwise of the spinning machine for receiving cross-wound packages therefrom and serving to deliver said cross-wound packages to one end of a transport path defined by said main transport belt; each of said cross-wound packages having a lengthwise axis extending substantially parallel to their direction of movement during transport upon said main transport belt; an auxiliary transport belt positioned substantially in alignment with said main transport belt and defining a transport path having a starting end adjoining said one end of said transport path of said main transport belt; means for limiting to an acceptable minimum, during the removal of said cross-wound packages from said spinning machine, any relative sliding movement between said auxiliary transport belt and said cross-wound packages; said limiting means comprising detector means for controlling the movement of said auxiliary transport belt; said detector means being arranged at a region where said transport path of said auxiliary transport belt neighbors said transport path of said main transport belt; said detector means being activated by said cross-wound packages on said transport belts in order to initiate movement of said auxiliary transport belt whenever one of said cross-wound packages passes said detector means; said limiting means further comprising stopping means for stopping said auxiliary transport belt after movement of the same through a distance at least approximately equal to the bobbin length of said cross-wound packages such that a successive arrangement of a closely spaced predetermined number of said cross-wound packages can be formed on said auxiliary transport belt; and said limiting means still further comprising removal means for removing in substantially frictionless manner at least one of said cross-wound packages from said auxiliary transport belt.
Claim 3
Dependent Claim
37 words
The apparatus as defined in claim 1, wherein: said stopping means comprises a detector activated by said cross-wound packages located upon said auxiliary transport belt; and said detector, when activated, initiating stoppage of said auxiliary transport belt.
Claim 4
Dependent Claim
16 words
The apparatus as defined in claim 1, wherein: said stopping means comprises a distance measuring device.
Claim 5
Dependent Claim
25 words
The apparatus as defined in claim 1, wherein: said detector means defines a common detector for effecting starting and stopping of said auxiliary transport belt.
Claim 6
Dependent Claim
92 words
The apparatus as defined in claim 2, wherein: said detector means comprises a first detector for initiating the starting of movement of said auxiliary transport belt; said detector of said stopping means being different from said first detector; and said detector of said stopping means being arranged at such a distance from said first detector that the amount of travel of said auxiliary transport belt within the time period between the starting and stopping of said auxiliary transport belt is at least approximately equal to said bobbin length of said cross-wound packages.
Claim 7
Dependent Claim
35 words
The apparatus as defined in claim 1, further including: a detector for generating a signal caused by a leading one of a number of cross-wound packages located upon said auxiliary transport belt passing said detector.
Claim 8
Dependent Claim
24 words
The apparatus as defined in claim 1, wherein: said removal means simultaneously remove said cross-wound packages arranged in succession upon said auxiliary transport belt.
Claim 9
Dependent Claim
35 words
The apparatus as defined in claim 7, wherein: said removing means comprises a cross-wound package grab means for simultaneously grasping and removing a plurality of said successively arranged cross-wound packages from said auxiliary transport belt.
Claim 10
Dependent Claim
61 words
The apparatus as defined in claim 7, wherein: said removing means comprise a trough extending substantially parallel and immediately adjacent to said auxiliary transport belt in order to receive said cross-wound packages arriving upon said auxiliary transport belt; and said removing means further comprising a cross-wound package pusher for displacing said cross-wound packages from said auxiliary transport belt to said trough.
Claim 11
Dependent Claim
65 words
The apparatus as defined in claim 1, wherein: said detector means comprises a multiplicity of detectors actuatable by means of said cross-wound packages moved upon said auxiliary transport belt and upon said main transport belt and supplying indicating signals; and said indicating signals being different for cross-wound packages assuming an undesired position in comparison to indicating signals generated by cross-wound packages assuming an orderly position.
Claim 12
Dependent Claim
