Carrying device for an apron drafting system

Abstract

An apron drafting system for a spinning machine as well as a carrying device for an apron drafting system of a spinning machine, with a first and a second support, each of which is configured for detachably accommodating an apron bridge and/or for rotatably bearing a drawing roller is provided. In order to provide a carrying device for an apron drafting system as well as an apron drafting system of a spinning machine, which enable an apron to be changed quickly, there is provision with the carrying device for the first support to have a base element and a guide section detachably connected to the base element and having a bearing opening for rotatably bearing the drawing roller as well as a first mounting opening for accommodating a first bearing section of the apron bridge.

What is claimed is: 
     
         1 . A carrying device for an apron drafting system of a spinning machine, with a first support and a second support, each of which is configured for detachably accommodating an apron bridge, for rotatably bearing a drawing roller, or both,
 characterized in that   the first support has a base element and a guide section which is detachably connected to the base element, the guide section has a bearing opening for rotatably bearing the drawing roller as well as a first mounting opening for accommodating a first bearing section of the apron bridge.   
     
     
         2 . The carrying device according to  claim 1 , characterized in that the carrying device has a base carrier on which the first support and the second support are arranged at a distance from one another, the base element being connectable to the base carrier. 
     
     
         3 . The carrying device according to  claim 1 , characterized in that the guide section is detachably connected to the base element via a linear guide in an operating position aligned in the longitudinal axis direction of the drawing roller and apron bridge. 
     
     
         4 . The carrying device according to  claim 3 , wherein the linear guide is a dovetail guide. 
     
     
         5 . The carrying device according to  claim 1 , characterized by a securing element for locking the guide section to the base element in the operating position. 
     
     
         6 . The carrying device according to  claim 5 , wherein the securing element is a securing screw. 
     
     
         7 . The carrying device according to  claim 1 , characterized in that the second support for detachably accommodating a second bearing section of the apron bridge comprises a second mounting opening with an entry slope running obliquely to an accommodating shaft, the accommodating shaft being configured in the operating position of the apron bridge by a shaft connecting the first and second mounting opening, and a first detenting spaced apart from the entry slope and delimiting the second mounting opening, which in the operating position is brought into engagement with a complementary second detenting on the second bearing section, in which case the second bearing section of the apron bridge is adjustable in the second mounting opening between the operating position and a release position in which the first detenting and the second detenting are disengaged. 
     
     
         8 . The carrying device according to  claim 7 , characterized in that the second detenting is configured as a slot, the first detenting is configured as a detent pin aligned perpendicular to the accommodating shaft, or both. 
     
     
         9 . The carrying device according to  claim 1 , characterized in that the carrying device is configured for carrying a drive unit, in which case the drawing roller is borne in a stationary manner on the drive unit with its end opposite the first support. 
     
     
         10 . The carrying device according to  claim 1 , characterized in that the apron bridge is borne in the operating position so as to be longitudinally displaceable along the accommodating shaft on the first support and the second support. 
     
     
         11 . An apron drafting system for a spinning machine having a carrying device with a bottom apron guided over a drivable bottom roller, the bottom apron being supported in the area of a main drawing zone by a sliding section of an apron bridge,
 characterized in that   the carrying device is configured with a first support and a second support, each of which is configured for detachably accommodating an apron bridge, for rotatably bearing a drawing roller, or both, wherein the first support has a base element and a guide section which is detachably connected to the base element, the guide section has a bearing opening for rotatably bearing the drawing roller as well as a first mounting opening for accommodating a first bearing section of the apron bridge.   
     
     
         12 . The apron drafting system according to  claim 11 , wherein the spinning machine is an air spinning machine.
