The automated systems have been installed in the spinning mill whenever the price/performance ratio was profitable. Automatic can changing devices on cards and drawing frames have become standard, as well as the automated doffing systems on roving frames and on spinning frames.
As to the linkages between the various machines and to the material handling, following systems gained ground:
· linkage between lap winder and combing machine, for lap transport
· transport system for the roving bobbin with bobbin change by six or three units. An overhead trolley removes the bobbins produced by the roving frame, in a number corresponding to a sixth of the machine spindles and conveys them to an overhead store-room situated in front of the spinning frame. With same system the empty tubes are removed from the spinning frame and brought to the roving frame.
· robotized systems for unloading the bobbins from the open-end spinning machines and from the winders and their loading on pin trolleys or on pallets. These last, as soon as full of cones, are wrapped with a polyethylene sheet , weighed and labelled. These equipments can be placed at the end of the machine or in fixed positions fed by a bobbin transport system.
