Supporting frame for a drafting system unit and drafting system comprising such a drafting system unit

Abstract

A supporting frame for a drafting system unit for drafting a fiber band at a workstation of a textile machine as well as a drafting system comprising such a drafting system unit. In order to make a drafting system and a drafting system unit available, the supporting frame has a coupling section and a locking unit for detachably connecting the supporting frame to an assigned workstation.

What is claimed is: 
     
         1 . A supporting frame for a drafting system unit for drafting a fiber band at a workstation of a textile machine, in which case the supporting frame has at least one bearing point for pivotably bearing a weighting arm assigned to the drafting system unit,
 characterised in that   the supporting frame has a coupling section and a locking unit for detachably connecting the supporting frame to the textile machine.   
     
     
         2 . The supporting frame according to  claim 1 , wherein the textile machine is an assigned workstation. 
     
     
         3 . The supporting frame according to  claim 1 , characterised in that the coupling section is configured for arrangement on a take-up section of the workstation for moving the supporting frame between a release position, in which the supporting frame can be removed from the assigned workstation, and an operating position, in which the supporting frame is arranged in a secure position at the assigned workstation for operation of a weighting arm bome on the supporting frame. 
     
     
         4 . The supporting frame according to  claim 3 , characterised in that the coupling section has a recess adapted to the take-up section. 
     
     
         5 . The supporting frame according to  claim 4 , wherein the take-up section is a frame brace of the textile machine. 
     
     
         6 . The supporting frame according to  claim 4 , characterised in that the recess is configured in one piece with the supporting frame. 
     
     
         7 . The supporting frame according to  claim 1 , characterised in that the locking unit has a detent body which can be moved between an opening position and a machine in an operating position of the supporting frame. 
     
     
         8 . The supporting frame according to  claim 7 , characterised in that the detent body is pretensioned in the direction of the latching position. 
     
     
         9 . The supporting frame according to  claim 1 , characterised in that the supporting frame is configured to accommodate a lower roller assigned to an upper roller ( 7 ) which can be arranged on the weighting arm for the rotationally movable bearing of the same. 
     
     
         10 . The supporting frame according to  claim 1 , characterised in that the supporting frame is configured to accommodate at least one additional aggregate. 
     
     
         11 . The supporting frame according to  claim 10 , characterised in that the at least one additional aggregate is an arrangement of a drive unit of the lower roller, a communication unit, a control device of the drive unit, or a combination thereof. 
     
     
         12 . The supporting frame according to  claim 10 , characterised in that the supporting frame has a fastening rail to accommodate the at least one additional aggregate. 
     
     
         13 . The supporting frame according to  claim 1 , characterised in that the supporting frame has two bearing points, each of which is for pivotably bearing a weighting arm. 
     
     
         14 . The supporting frame according to  claim 13 , characterised in that two weighting arms bear at least one upper roller between the two weighting arms. 
     
     
         15 . The supporting frame according to  claim 1 , characterised in that the supporting frame has a handling element. 
     
     
         16 . The supporting frame according to  claim 1 , characterised in that the handling element is a gripping element. 
     
     
         17 . A drafting system for a textile machine comprising a drafting system unit having a weighting arm with at least one upper roller, characterised in that the drafting system unit has a supporting frame having a coupling section and a locking unit for detachably connecting the supporting frame to the textile machine, on which the weighting arm is pivotably borne. 
     
     
         18 . The drafting system according to  claim 17 , characterised in that two weighting arms with at least one upper roller between the two weighting arms are arranged on the supporting frame, the weighting arms being connectable or connected to each other via a gripping element.
