The invention discloses a vertical shaft type ring
spinning automatic
yarn falling device, and belongs to the technical field of ring
spinning yarn falling devices. The device comprises a frame, a base, a motor, a traveling mechanism, a positioning mechanism, a pre-loosening mechanism, a
yarn falling transmission mechanism and a
manipulator. By the matching between the positioning mechanism and the yarn falling transmission mechanism, the
manipulator can be positioned relative to a caught
bobbin when the frame moves forwards; and by the matching between the yarn falling transmission mechanism and the
manipulator, horizontal revolving and
vertical motion of the manipulator and a function of opening and closing the manipulator are realized, so that the aim of vertically pulling out the
bobbin from a spindle blade is comprehensively fulfilled. The device adopts a yarn falling mode that the tops of yarns are in contact with the
bobbin, so that the yarns cannot be damaged; the bobbin can be continuously pulled out, and the yarn falling efficiency is high; by the matching between the yarn falling transmission mechanism and the pre-loosening mechanism, before the manipulator upwards pulls out the bobbin, the bobbin and the spindle blade relatively rotate to realize loosening, so that the pre-loosening effect is good; complicated sensing control is not needed, the volume is small, and the weight is light; and when the vertical shaft type ring
spinning automatic yarn falling device is used, the existing ring spinning
machine does not need to be improved.
