Method for cleaning a spinning rotor of open-end spinning machine having at least one spinning device, and a cleaning device for cleaning a spinning rotor

A method for cleaning a spinning rotor of a spinning device in an open-end spinning machine in which at least one cleaning measure is carried out on the spinning rotor with the aid of a pneumatic or a mechanical cleaning device, comprising:

• storing parameters in a memory bank, wherein settings for carrying out the cleaning measure are automatically determined by a control unit associated with the open-end spinning machine based on present parameters of the spinning device;
• with a control unit associated with the open-end spinning machine and the memory bank, specifying settings for carrying out the cleaning measure by one or both of:
• previously empirically determined settings for carrying out the cleaning measure suitable for the present parameters of the spinning device stored in the memory bank;
• or
• rules for determining the settings suitable for the present parameters of the spinning device stored in the memory bank;
• wherein a cover element of the spinning device is at least partially opened in order to carry out the cleaning measure;
• wherein the parameters comprise at least type of a channel insert adapter or type of the spinning rotor, and the settings include at least an opening angle of the cover element of the spinning element;
• and
• wherein the cleaning measure comprises multiple cleaning steps and assigned to each of the cleaning steps is a separate opening angle of the cover element.

• or
• rules for determining the settings suitable for the present parameters of the spinning device stored in the memory bank;
• wherein the cleaning measure is carried out with a cleaning device that is situated in a movable maintenance unit and is initially advanced toward the spinning rotor to be cleaned and, subsequently, the spinning rotor is accelerated to a defined cleaning speed with a drive and, once the cleaning speed has been reached, or thereafter, a cleaning element of the cleaning device is brought into action on the spinning rotor and the spinning rotor is cleaned;
• wherein the defined cleaning speed is less than an operating speed of the spinning rotor;
• and
• wherein the drive is shut down once the cleaning speed has been reached, and subsequent to the spinning rotor running down, the spinning rotor is accelerated back to the cleaning speed again with the drive and the cleaning element is brought into action on the spinning rotor again.

An open-end spinning machine, comprising:

• a spinning device, the spinning device comprising a spinning rotor;
• a cleaning device configured to carry out a cleaning measure on the spinning rotor;
• a control unit associated with the open-end spinning machine, the control unit configured to:
• automatically determine settings for the cleaning measure using stored parameters in a memory bank based on present parameters of the spinning device by one or both of:
• previously empirically determined settings for carrying out the cleaning measure suitable for the present parameters of the spinning device stored in the memory band;
• or
• rules for determining the settings suitable for the present parameters of the spinning device stored in the memory bank;
• a cover element of the spinning device that is at least partially opened in order to carry out the cleaning measure;
• and
• wherein the settings include an opening angle of the cover element that is changeable and determined based on one or both of the parameters of type of the spinning rotor or type of a channel insert adapter used with the spinning rotor and rotor.
