Problems solved by technology

[0006] However, this embodiment has the disadvantage that the required torque at the drive shaft must be relatively accurately known to the control of the auxiliary drive motor in order that the drive torque introduced by the auxiliary drive motor has correct size
One such opening of the pressurized frame is usually performed by the operator and is difficult to account for by the control of the auxiliary drive motor

Embodiment Construction

[0017] Only two such drafting units are designated here with the reference number 1 , which are likewise referred to as machine parts in this application. Such a drafting unit 1 usually consists of a plurality of roller rows 2 , 3 and 4 , wherein the last roller row in the direction of transport of the fiber material to be spun is designated as drive shaft 5 . This refers to the drafting mechanism feed roller 4 .

[0018] The roller rows 2, 3, 4 of the drafting mechanism 1 are originally driven by the original drive 6, which includes the original drive motors 7 and 8 and the transmissions 9 and 10 as main components. The original driving motor 7 drives the two roller rows 2 and 3 through the transmission device 9 . The original drive motor 8 is connected with the drive shaft 5 in the original state through the transmission device 10, and drives the drafting mechanism to supply the cylinder 4 before the machine is refitted. The primary drive motors 7 , 8 are connected to a fr...

Abstract

A drive device for a spinning machine or a twisting machine comprises an original drive device affixed to at least a machine part driving shaft. A transferable driving moment transferred by the original drive device is not available due to complementary machine modifications. The machine modifications comprise a remodeling drive device affixed to a driving shaft having at least a remodeling drive motor. The original drive device is no longer connected to the driving shaft, and the torque is not transferred between the original drive device and the driving shaft. A revolution speed sensor is connected with a member which belongs to the original drive device, wherein the member distributes a rated value of rotating speed to the modified driving motor. The modified driving motor preferably comprises a rotating speed regulation to adjust the rotating speed to the rated value.

Description

technical field [0001] The invention relates to a drive device for a spinning or twisting machine, comprising at least one original drive device associated with a drive shaft of a machine part, the transmissible drive torque of which is no longer sufficient due to supplementary machine modifications used, wherein the machine retrofit includes a retrofitted drive unit associated with the drive shaft, which has at least one retrofitted drive motor. Background technique [0002] In practice, old spinning or twisting machines are often modernized by a supplementary addition or conversion, which is always accompanied by an increase in machine power. For example, the drafting unit can be retrofitted with a device which can additionally also spin the core yarn. Or each drafting mechanism can be supplemented with these devices, as they are known by DE 100 52 878 A1, and its purpose is to make the fibers not yet twisted by the side collection of its edge fibers before obtaining spin...
