Method and device for yarn traversing upon winding the yarn on a bobbin

Abstract

The invention relates to method of yarn traversing upon yarn winding on a bobbin (7) with cheese package at which the yarn is wound on a bobbin with forced rotation (7), while the yarn passes through the traversing guide mounted on the traversing element (1), which moves reversibly between the left and right dead centre. The traversing element (1) is subject to acting of the draw bar (2) on rotatably mounted main crank (3), whose angle speed by means of a rotating electronic controllable drive (4) controlled by a control device (5) upon movement of the traversing element (1) from one dead centre to the second dead centre continuously slows down or accelerates in a direct dependence on a required angle value of yarn crossing on a bobbin being wound (7) and / or in a direct dependence on a position of traversing element (1), through which the required angle of yarn crossing on the bobbin being wound (7) and / or required course of speed of motion of the traversing element (1) is achieved. The invention also relates to the device for yarn traversing upon yarn winding on a bobbin (7) with cheese package, at which the yarn is wound on a bobbin with forced rotation (7), while the yarn passes through the traversing guide (6) mounted on the traversing element (1), which moves reversibly between the left and right dead centre. To the traversing element (1) by its one end there is rotatablyconnected a draw bar (2) whose second end is rotatably connected with the rotatably mounted main crank (3) coupled with the movable section of the electronic controllable rotation drive (4) coupled with the control device (5).

Description

technical field [0001] The invention relates to a method for yarn guidance by winding the yarn on bobbins with cheese packages, the yarn being wound on the bobbins forced to rotate while the yarn passes through The transverse guide is reversibly movable between left and right dead centers. [0002] The invention also relates to a device for guiding the yarn by winding the yarn on a bobbin with a cheese package, the yarn being wound on the bobbin forced to rotate while the yarn passes through a transverse element mounted on The transverse guide can be moved reversibly between left and right dead centers. Background technique [0003] The technical solution for guiding the yarn when winding the yarn on the bobbin is mainly based on a system of pulley guides located in shaped guide grooves, guides of a pair of pulleys in a transverse disc or on a shaped guide rib of a transverse disc while the pulley is connected to the transverse rod of the transverse guide carrying the woun...

Problems solved by technology

[0007] Despite the ease and rapidity of set-up and the possibility of making required changes in the parameters of the transverse rod motion (possibly controlled by a linear motor electronic controller for the rod), the main drawback of this arrangement is the changing momentum of the direction of motion of the transverse rod, e.g. The action of the inertial force partly related to the inaccuracy of the part in the dead center, which is partly related to the mechanical stress of the transverse rod

Another drawback is the high cost of acquisition
