(54) Doffing apparatus


(57) A textile machine represented by an automatic winder (1, 103) including multiple winding units (2, 112) arranged in a row and a doffing apparatus (3, 103) capable of running in an arrangement direction of the winding units. The winding units wind on a winding tube (7, 133) a spun yarn that is unwound from multiple yarn supplying bobbins (5) while performing yarn joining thereby creating a fully-wound package of a specific yarn amount. The doffing apparatus (3, 103) of the automatic winder (1, 103) includes, for example, a cradle opener (32, 140) that performs opening/closing operation and raising/lowering operation of a cradle (12, 132), and a yarn catching unit (60, 145) that catches a yarn end on the yarn supplying bobbin side and guides the yarn end to a winding tube (7, 133). The cradle opener (32, 140) is raised or lowered by a fluid pressure cylinder (38, 158) and opened or closed by a driving motor (52, 152, 156). The yarn catching unit (60, 145) is driven by a driving source (62, 171, 182).
