Abstract

The invention relates to a vibration-damping apparatus ( 18 ) for a winding device ( 4 ) of a textile machine ( 1 ), which textile machine produces cross-wound packages ( 5 ), the vibration-damping apparatus being provided for reducing the vibrations that occur at the pivotably mounted package cradle ( 8 ) during the winding operation of the textile machine ( 1 ).
According to the invention, in order to obtain a vibration-damping apparatus which is unproblematic both with regard to safety and with regard to contamination and which also always ensures a vibrationally relatively stable state of the package cradle, the vibration damper is in the form of a friction damper ( 20 ) having friction forces of different intensity depending on the working direction, the friction forces acting as the cross-wound package ( 5 ) lifts off during the winding operation being greater than the friction forces acting during the return of the cross-wound package ( 5 ).

First claim

The invention claimed is:

1. A vibration-damping apparatus ( 18 ) for a winding device ( 4 ) of a textile machine ( 1 ) that is configured to produce cross-wound packages ( 5 ), the vibration-damping apparatus ( 18 ) being configured for reducing vibrations that occur at a pivotably mounted package cradle ( 8 ) during a winding operation of the textile machine ( 1 ), the vibration-damping apparatus ( 18 ) comprising:
a friction damper ( 20 ), configured to exert friction forces of different intensities, depending on a working direction, the friction damper ( 20 ) comprising:
a braking rod ( 32 ), mounted for sliding relative to a damper housing ( 31 ) of the friction damper ( 20 );
a stationary first braking element ( 39 ); and
a movably mounted second braking element ( 41 ), configured to be placed against the braking rod ( 32 ) via a movable support lever ( 38 ),

wherein:
friction forces that are effective as a cross-wound package ( 5 ) lifts off during a winding operation are greater than friction forces effective during a return movement of the cross-wound package ( 5 ), and
one end of the movable support lever ( 38 ) is connected to the second braking element ( 41 ) such that limited movement is allowed, while another end is supported in a guide ( 35 ) of the damper housing ( 31 ) via a guiding and arresting device ( 36 ).

2. The vibration-damping apparatus ( 18 ) according to claim 1 , further comprising a spring element ( 42 ) configured to act, in frictional contact, on the movable support lever ( 38 ),
wherein the support lever ( 38 ) is arranged at an angle to the braking rod ( 32 ).

3. The vibration-damping apparatus ( 18 ) according to claim 2 , wherein the spring element ( 42 ) comprises a compression spring ( 42 ), wherein the compression spring ( 42 ) is configured such that an effective compressive force of the compression spring ( 32 ) can be set in a defined manner via an adjustment screw ( 43 ).

4. The vibration arresting apparatus ( 18 ) according to claim 1 , wherein the guiding and arresting device ( 36 ) is configured to form a pivoting and support point ( 37 ) for the movable support lever ( 38 ) and is mounted in the guide ( 35 ) of the damper housing ( 31 ) such that the guiding and arresting device ( 36 ) can be slid therein and can be positioned therein in a defined manner.

5. The vibration-damping apparatus ( 18 ) according to claim 1 , wherein the guide ( 35 ) is part-circular-shaped.

6. The vibration-damping apparatus ( 18 ) according to claim 1 , wherein the first braking element ( 39 ) and the second braking element ( 41 ) are identical.

7. The vibration-damping apparatus ( 18 ) according to claim 6 , wherein the first braking element ( 39 ) and the second braking element ( 41 ) are each equipped with:
through-bores ( 40 ) configured to enable fastening, and
a recess ( 45 ) for an exchangeable brake lining ( 46 ).
