Winding machine fixing mechanism, winding machine and method for coupling and/or decoupling a winding sleeve to or from a winding spindle of a winding machine

A winding machine comprising a winding machine fixing mechanism for fixing a winding sleeve on a winding spindle comprising

• a) a fixing position and a release position,
• b) a motion control which actuates the winding machine fixing mechanism from the release position to the fixing position and from the fixing position to the release position,
• c) a fixing device which fixes the winding sleeve on the winding spindle and
• d) a catch which causes an actuation of the winding machine fixing mechanism and which is entrained by a movement of the winding sleeve during the motion control,
• e) the fixing device comprising at least one spreading element and at least one fixing element,
• f) the spreading element and the fixing element bearing against one another via at least one slanted surface,
• g) a movement of the catch causing a relative movement of the spreading element and the fixing element, the relative movement being guided by the slanted surface, the relative movement leading to a change of a distance of the fixing element from a longitudinal axis of the winding spindle,
• h) the fixing element comprising a fixing section that, after the winding sleeve has been slid on, is arranged behind the winding sleeve in a direction for sliding on, the fixing section being arranged radially outside of an inner diameter of the winding sleeve,
• i) the fixing section forming an axial stop for the winding sleeve that opposes or blocks a withdrawal of the winding sleeve from the winding spindle.

A winding machine fixing mechanism for fixing a winding sleeve on a winding spindle comprising

• a) a catch which
• aa) causes an actuation of the winding machine fixing mechanism from a release position to a fixing position,
• ab) is entrained by a movement of the winding sleeve when pushing the winding sleeve onto the winding spindle and
• ac) is mechanically coupled to a fixing element such that a movement of the catch causes a movement of the fixing element,
• b) wherein in the fixing position of the winding machine fixing mechanism the winding sleeve is axially clamped between a contact surface of the catch and an inclined contact surface of the fixing element, wherein the contact surface of the catch is embodied as a contact cone,
• an inner surface of the winding sleeve being free of contact with the winding spindle between an end portion of the winding sleeve contacted by the contact surface of the catch and an end portion of the winding sleeve contacted by the inclined contact surface of the fixing element.
