Title: Empty bobbin sleeve collection -  has build=up conveyor surface stretch for compressed air to pass through and move them without friction damage
Inventor: BUNGTER HELMUT
IPC: D01H9/18
Filed: 1990-09-27
Abstract: Appts. to collect a group of empty bobbin sleeves, after doffing, in the conveyor system, has a stretch to collect them on their carriers (20) in prepn. before the transfer point to the spinners. The collection stretch is formed as a build-up conveyor path (16) with openings in the conveyor surface (15) to blow air through from a compressed air supply (13). Pref. in addn. to the conveyor surface (15), blower openings are at the edges of the build-up conveyor (16), esp. at guide rails with their inner sides directed at the conveyor surface (15). The under side of the base plate (19) for each tray (20), towards the conveyor surface (15), is flat and free of any contours, or the under side of the base plate has a sawtooth profile in a ring round the centre axis of the holding spindle (22). In each tooth gap, in a radial direction outwards, the angled tooth flank precedes the straight tooth flank. The blower openings are set on a narrow strip along the centre of the conveyor surface (15), along the direction of travel, less than one-third of the conveyor path width, to reduce compressed air loss when the trays (20) are tightly together as they move along in successin. ADVANTAGE - System moves the bobbin sleeve carriers positively along their direction of movement towards the transfer point, but without friction and without damaging the carriers or the conveyor path.
