Abstract
Abstract A device for the removal of bobbins from an automatic rotor spinning machine having a conveyor belt placed on the automatic spinning machine for collecting and delivering completed bobbins comprises a transfer device with a frame, a receiving conveyor belt swiveling on the frame in a vertical direction for receiving bobbins from the automatic spinning machine, a roller conveyor section extending the receiving conveyor belt and which can be swiveled between a position inclined in the direction of feed and a horizontal position, a receiving chute placed parallel to the roller conveyor section, a pusher for transfer of bobbins from the roller conveyor section to the receiving chute, a lifting device for vertically moving the receiving chute between a position adjacent to the roller conveyor section and a number of additional positions, and a tilting device for tilting the receiving chute around its longitudinal axis between a horizontal receiving position and a position essentially at a 90° angle to it for ejecting the bobbins into a magazine cart.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
A device for the removal of bobbins from a top conveyor belt of an automatic rotor spinning device to a magazine cart, said device comprising: a transfer frame; a receiving conveyor belt having one end mounted on said transfer frame for pivoting about a first horizontal axis to a position for receiving bobbins from said spinning device conveyor belt at the other end thereof; a roller conveyor section having one end mounted on said frame for pivoting about a second horizontal axis between an inclined position wherein said roller conveyor section forms an extension of said receiving conveyor belt and a horizontal position wherein said roller conveyor section is horizontal; receiving chute means positionable adjacent said roller conveyor section in said horizontal position; pusher means movable for transferring bobbins from said roller conveyor section in said horizontal position to said receiving chute means; means for mounting and vertically moving said receiving chute means on said frame means; and means for tilting said receiving chute means to a bobbin ejection position, said tilting means being located on said vertically moving means, whereby the bobbins may be transferred to the magazine cart.
Claim 2
Independent Claim
190 words
A device for the removal of bobbins from a top conveyor belt of an automatic rotor spinning device to a magazine cart, said device comprising: a transfer frame; a receiving conveyor belt having one end mounted on said transfer frame for pivoting about a first horizontal axis to a position for receiving bobbins from said spinning device conveyor belt at the other end thereof; a roller conveyor section having one end mounted on said frame for pivoting about a second horizontal axis between an inclined position wherein said roller conveyor section forms an extension of said receiving conveyor belt and a horizontal position wherein said roller conveyor section is horizontal; receiving chute means positionable adjacent said roller conveyor section in said horizontal position; pusher means movable for transferring bobbins from said roller conveyor section in said horizontal position to said receiving chute means; means for mounting and vertically moving said receiving chute means on said frame means; and means for tilting said receiving chute means to a bobbin ejection position, said tilting means being located on said vertically moving means, whereby the bobbins may be transferred to the magazine cart.
Claim 3
Dependent Claim
39 words
