<p>PCT No. PCT/EP81/00187 Sec. 371 Date Jul. 6, 1982 Sec. 102(e) Date Jul. 6, 1982 PCT Filed Dec. 2, 1981 PCT Pub. No. WO82/02186 PCT Pub. Date Jul. 8, 1982.The present invention concerns an apparatus for sorting conical bobbin tubes, using trough-shaped transporting pockets, into which the bobbin tubes are placed individually, and in which they are shifted at a bias to their longitudinal direction. According to the invention the bobbin tubes pass under two rolls, which with respect to the direction of this movement are arranged inclined at an angle in the same sense, and which are mounted on a frame which is pivotable about an axis. One, and only this one of the rolls, namely the one, under which the bobbin tube zone of greater diameter passes, contacts the bobbin tube, and owing to its inclined arrangement effects a shifting movement of the bobbin tube in its longitudinal direction. In this manner the bobbin tubes are shifted into different positions depending on the position of their bobbin tube foot ends relative to their tip ends, and in this manner are sorted. A main application of the invention is seen in the use for supplying bobbin tubes, with the same ends oriented towards the same side, to the bobbin transporting belt of ring spinning and ring twisting machines. On such machines the bobbin tubes, once sorted, can be arranged, e.g. using a drop chute, with the same ends to the same side in simple manner. A substantial advantage of the invention is seen in that the apparatus adapts automatically to bobbin tubes of varying diameters. Furthermore, no parts impeding the bobbin tube shifting movement are present.</p> |
