Energy storage means for a yarn guide of a textile machine for producing a cross-wound bobbin

Abstract

This energy accumulator has at least two permanent magnets arranged in fixed positions and one permanent magnet capable of traversing with the finger yarn guide. These permanent magnets are arranged so that poles in the same direction face to each other, and the permanent magnets arranged in the fixed positions are positioned near a motor shaft of an electric mechanical driving device, which is formed with a finger thread guide turning shaft in a left or a right turning range of the finger yarn guide, so that magnetic force of the permanent magnets returns the finger yarn guide to a central area, wherein magnetic force of the permanent magnets are neutral, in the condition that the driving device is disconnected.

Description

technical field [0001] The invention relates to an energy store according to the preamble of claim 1 . Background technique [0002] It is well known that in order to manufacture spinning packages at least two prerequisites must be fulfilled. On the one hand, the spinning package must be rotated and, on the other hand, the yarn wound onto the rotating spinning package must be traversed along the package axis. [0003] If the yarn traverses slowly, a spinning package is formed in which the wound yarns are as parallel as possible. If such a spinning package is to have a relatively large volume and a flat end face arranged substantially perpendicular to the axis of the package, there must be limiting discs on both sides of the winding. If the yarn traverses rapidly so as to form cross-winding, the use of limit discs can be avoided. Since modern spinning machines are known to operate at relatively high winding speeds when making cross-wound bobbins, high traversing rates are ...

Problems solved by technology

[0007] Such accumulators of course have various disadvantages: due to the relatively rapid braking of the yarn guides when they hit the respective accumulators, the entire laying system is stressed, for example, and thus must be operated at high speeds. stability, which significantly increases the mass and inertia of the laying system

[0010] However, the rotary spring has been a possible weak point of such a well-adjusted reciprocating device, which works perfectly in theory and in practice, and the service life of this spring may not be reliable enough to meet the requirements proposed for such a laying system. strict requirements
