Description

[Detailed description of the invention] A method for cleaning worms of a ring spinning machine and an apparatus for carrying out the same method The present invention resides in the following claims. Regarding the worm cleaning method for ring spinning machines described in the preamble to paragraph 1 and the equipment for carrying out the method, It is something to do.

The contents of DE-PS 1267154 include: The device consists of a serrated scraper and a suction device. Ru. According to an embodiment, the device runs along the spinning machine together with a kelp pulling device; Removes windings of the spindle warb thread as it passes through. The whole device is two cars It is suspended by wheels on a running rail attached along the ring spinning machine. It is supported against the guide rail by one other wheel. serrated scre The bar is elastically supported and therefore fits into the annular groove in which the spindle is to be cleaned. Fits in elastically. This results in considerable wear in the area of this annular groove. be done. However, the main drawback of this device is that the period of contact with the annular groove is relatively short. This is because the cleaning effect is not satisfactory.

Cleaning devices of the type mentioned at the beginning are the subject of EP-A 0251397, this The device can also run along rails provided in the floor below the spinning machine.

This device has a head consisting of a canter, a suction nozzle, and a rotating round brush. I'm being kicked. Movement of the equipment along the spinning frame is carried out by Geneva gears; The gears are located below the spindle support plate (spindle rail). Engages a pin aligned with the spindle axis. The head moves in synchronization with the movement along the spinning machine. performs a reciprocating lateral movement extending perpendicular to the longitudinal movement, in which case the device When the head approaches the spindle, the head moves so that it is in contact with the spindle, and the device moves further away from the spindle.

Here again, the cleaning effect is not satisfactory. This is because the cleaning head is spindle. This is because it only engages with the annular groove of the ring for a relatively short period of time. However, the engagement time is longer If you try to remove the cleaning device, it will move along the spindle support plate at a very low speed. The drawback is that it cannot be moved.

Based on that, we have improved the worm cleaning device so that the cleaning head can spin for a sufficiently long time. the speed at which the device engages the annular groove of the spindle and moves along the spindle support plate in that case The challenge is to prevent this from being reduced.

This object is solved by the features of claim 1.
