Abstract (en)

Embodiments of this disclosure provide a single doffing device and a single doffing control method and control apparatus. The device includes: a spinning machine workstation (100) having a spinning mechanism (101) and a winding mechanism (102), wherein the winding mechanism (102) is provided with a replaceable tube (1021); a control apparatus (12) configured to, when a yarn is wound into a yarn bobbin (1022) of a predetermined size around the replaceable tube (1021) on the winding mechanism (102), transmit control information for instructing to replace the yarn bobbin (1022) on the winding mechanism (102); and a tube replacement apparatus (202) storing one or more tube(s) (1021) therein and configured to replace the yarn bobbin (1022) on the winding mechanism (102) by using one of the stored tubes upon receipt of the control information. Hence, the yarn bobbin (1022) is replaced with an empty tube (1021) automatically after the yarn winding is completed, thereby eliminating or avoiding artificial intervene, lowering maintenance cost, and improving security and operational efficiency.
