Rotor drive of an open-ended spinning apparatus

Abstract

The invention relates to a rotor drive (18) of an open-ended spinning apparatus (1) which has a bearing arrangement (5) for the support of a spinning rotor (3) which rotates at high frequency and is mounted without contact. A rotor shaft (4) of the spinning rotor (3), formed as a runner, is held during the spinning process freely hovering between a front and back bearing (6, 7) of the rotor drive (18). For the conductive discharge of the electrostatic charge occurring during the spinning process,the spinning rotor (3) is distanced from one of the bearings (6, 7) in such a way that when a specified electrostatic charge is reached, a voltage sparkover between the spinning rotor (3) and the bearing (6, 7) occurs, and in such a way that the rotor drive (18) is surrounded by a rotor drive housing (37) which is electrically conductive and grounded and to which the bearing (6, 7) serving for the conductive discharge is conductively connected.

AI Technical Summary

Benefits of technology

This patented technology allows for better controllability over how much energy accumulates at certain points along with prevention of damage or malfunctions due to static charges generated while manufacturing processes are being carried out. It achieves this by connecting both the spinner's driving apparatus (rotors) and its supports together into a single structure called a machine frame. When there is no excess potential difference across any two structures, they work like capacitors without causing problems. However, if too many electrons enter their space, then some will get trapped inside instead of moving around freely within the spaces where they were previously located. To solve this problem, the system includes a separate circuit board attached to each side of the motor body. Each plate carries multiple circuits and connects to different terminals on the rotator drive housing through wires. These connections help reduce impedance issues and improve signal quality. Additionally, the use of insulating suspending material reduces unwanted signals and improves overall performance. Overall, this design ensures stable operation even under high levels of stress and provides improved efficiency compared to previous designs.

Problems solved by technology

This patented technical solution describes different ways how to prevent static electricity charged off while spunting fibers or other material through an opening spinning machine (open end) without causing damage. One method involves isolating the spinging rotors' bearings between them and connecting it directly to their grounding parts. Another approach uses conductive elements like springs instead of physically touching them, but also includes applying pressure against these conductive areas to keep the rotation stable over time.
