Paper roll handling apparatus

摘要

Paper roll handling apparatus comprising an elevated member supported for rotation about a vertical axis and having a plurality of roll suspending devices in angularly spaced relation about the axis and selectively operable to engage and suspend rolls to be carried by the member and for releasing the rolls, the member being driven step-by-step to advance the suspending devices successively into positions related to a plurality of angularly spaced stations. The elevated member may be in the form of a ring-shaped carriage having a rim riding on supporting rollers. Spoke-like beams supported by the carriage ring and by a hub mounted rotatably on a center post support the roll suspending devices each of which has reciprocably operable probe mandrels for engaging in the cores of rolls to be suspended. Means are provided for selectively rotating the rolls through one of the mandrels of each of the suspending devices. Indexing means accurately align the suspending devices with the successive spaced stations.
