DEVICE FOR TAKEDOWN OF THE ARTICLE BEING FORMED, FOR CIRCULAR KNITTING MACHINES

摘要

A device for takedown of the article being formed, for circular knitting machines, comprising at least one takedown roller (2), which is supported, so that it can rotate about its own axis, by a supporting structure (3) and can engage, by means of its lateral surface, the article (4) to be taken down. There is a motor element (10), which can rotate with a reciprocating motion, along an arc of rotation, about a main axis (2a), and there are actuation means (11), which operate on the motor element (10) to turn it about the main axis (2a) in a first direction of rotation (41). There are also reloading means (12), which operate on the motor element (10) to cause its rotation about the main axis (2a) in a second direction of rotation (42) that is opposite to the first direction of rotation (41). Unidirectional connection means (13) are interposed between the motor element (10) and the takedown roller (2) for connecting the takedown roller (2) to the motor element (10) in its rotation in the first direction of rotation (41) and for disconnecting the takedown roller (2) from the motor element (10) in its rotation in the second direction of rotation (42). The reloading means (12) comprise a fluid-operated reloading cylinder (14), which is supported by the supporting structure (3) and operates with the stem (15a) of its piston (15) on the motor element (10) with a reloading force (FR) that is oriented along a direction spaced from the main axis (2a) for applying to the motor element (10) a reloading torque (CR) that is oriented concordantly with the second direction of rotation (42).
