Problems solved by technology

Disturbances on the motor shaft occur due to changes in load, vibration of the belt, etc., so these disturbances cannot be effectively eliminated
The result is an impairment of running calm during constant operation and an asynchrony between the rollers of the drafting system

Embodiment Construction

[0024] figure 1 An adjusted drafting device 1 according to the invention is shown schematically, comprising a pair of input rollers, a pair of intermediate rollers and a pair of output rollers. exist figure 1 Only the bottom rollers of these roller pairs are shown in , that is, input bottom roller 2, intermediate bottom roller 3 and output bottom roller 4. Only these bottom rollers 2, 3, 4 are driven, whereas top rollers, not shown, are pressed against the respective bottom rollers 2, 3, 4, so that the schematically directed fiber strip FB is clamped between the roller pairs. Both the bottom rollers 2, 3 are driven by a common electric motor 10, which produces a specified pre-draft via a transmission stage (not shown in more detail) with a belt drive 6 located between the input and intermediate roller pairs. stretch. The output bottom roller 4 is driven by a separate electric motor 20 via a belt drive 7 (not shown in more detail). The rpm of the electric motors 10, 20 can ...

Abstract

Disclosed is a drafting arrangement for a spinning machine, particularly a draft regulator, comprising at least two successive pairs of rollers, several electric motors (10, 20) for driving at least one respective roller (2, 3, 4) belonging to said roller pairs, and an electronic regulating ring (5) to which the electric motors (10, 20) are connected. The drafting arrangement is characterized in that an acceleration sensor (12, 22) is allocated to at least one electric motor (10, 20) and / or at least one roller (2, 3, 4).

Description

technical field [0001] The invention relates to a drafting device for a spinning machine, in particular an automatic leveler draw frame, comprising at least two consecutive roller pairs, several electric motors for driving at least one roller of said roller pairs respectively and An electronic control unit connected to the motor. Background technique [0002] In a controlled drafting system, the exact synchronization of the roller pairs of the drafting system is decisive for the quality or evenness of the produced fiber sliver. Mechanical connections via gearwheels or belt drives are particularly ideal for this, since these connections ensure a substantial synchronicity of the roller pairs. However, these connections are not optimal for automation. [0003] The use of several direct drives, so-called individual drives, for driving the drafting plant elements makes it possible to automate the machine settings for drafting and elongation. Drafting devices with such individu...
