  • Publication number: 20050098525
    Abstract: Apparatus for removing a bobbin deposited by a bobbin winding device includes a traveling unit suspended from an overhead track and having a drive comprised of an electric motor and a driving roller rolling along the track. A gripping device has at least two gripper arms for grabbing a bobbin in a jaw-like manner, whereby the gripper arms are urged by a mechanical spring assembly against a bobbin surface and can be released from the bobbin surface through pneumatic or electric energy in opposition to the spring assembly. A motor-driven hoisting device connects the gripping device to the traveling unit and moves the gripping device between up and down positions, wherein the gripping device is centered in the traveling unit, when assuming the up position. Flexible supply lines are provided to feed power to the traveling unit and the gripping device and extend between one end of the track and a connection of the traveling unit.

  • Patent number: 6769854
    Abstract: An arrangement for exchanging empty bobbins with full bobbins includes a creel having lateral delivery positions for holding filament-carrying bobbins for delivery of filaments to a textile machine. Disposed above the creel is a bobbin carrier which has several transport positions for bobbins and is moveably guided in a rail for travel in suspended disposition along a travel path. Transfer units are positioned on either side of the creel for transferring bobbins between the creel and the bobbin carrier and include an upright moveable along the creel and at least one support moveable along the upright and having receptacles for the bobbins. The receptacles are moveable horizontally relative to the support, wherein the delivery positions of the creel that neighbor the transfer unit are provided at a number and at a distance which corresponds to a number of and a vertical distance of the transport positions on the bobbin carrier.
