Apparatus for sorting conical bobbin tubes of textile machines

Abstract

An apparatus for sorting conical bobbin tubes for textile machines with their tip ends located to one side comprises a supply device supplying individual bobbin tubes transversely of their axes along a guide table and between two lateral guide edges. The distance of the lateral guide edges from the guide table is equal to the mean bobbin tube diameter and the mutual distance between which diminishes, seen in the direction of the bobbin tube supply, from a value greater than the bobbin tube length to a value smaller than the bobbin tube length. During their movement in the supply direction the bobbin tubes are forced to move longitudinally in the direction of their tip end, which permits sorting them with their tip end to one side. For also automatically sorting bobbin tubes of varying diameter with their tip end to one side, the guide edges are connected with a feeler, designed as a rod, which checks the mean bobbin tube diameter, in such a manner that their distance from the guide table always corresponds to the mean bobbin tube diameter.
