Bobbin winding machine

Abstract

A bobbin winding machine with a plurality of winding stations which are arranged along a bobbin winding spindle for winding a plurality of threads into bobbins is described. The winding stations are assigned a traversing device which has a flyer traversing unit for each winding station. The flyer traversing units are driven jointly and for this purpose have in each case a drive wheel which is coupled to a driven driving wheel via a toothed belt. The toothed belt is coupled to the toothed drive wheels and to the toothed driving wheel via a toothed profile side.

1 . Bobbin winding machine with a plurality of winding stations which are arranged next to one another along a bobbin winding spindle and wind a plurality of threads in parallel into a plurality of bobbins, and with a traversing device which has a flyer traversing unit for each winding station, the flyer traversing units being assigned a plurality of drive wheels which are arranged next to one another and which are coupled via a toothed belt to a driven toothed driving wheel for driving the flyer traversing units, wherein the toothed belt is coupled to the toothed drive wheels and to the toothed driving wheel via a toothed profile side. 
     
     
         2 . Bobbin winding machine according to  claim 1 , wherein one of a plurality of deflecting rollers is arranged between adjacent drive wheels, and in that wherein the deflecting rollers guide the toothed belt on an opposite flat side. 
     
     
         3 . Bobbin winding machine according to  claim 2 , wherein the deflecting rollers have in each case a guide casing with one or more continuous guide grooves, and wherein the toothed belt can be guided on the flat side by the guide casing with or without an endless longitudinal web. 
     
     
         4 . Bobbin winding machine according to  claim 1 , wherein the flyer traversing units, the drive wheels and the driving wheel are arranged on a plate-shaped traversing carrier which is held moveably in a machine stand. 
     
     
         5 . Bobbin winding machine according to  claim 4 , wherein a plurality of damping elements are arranged between the traversing carrier and the machine stand. 
     
     
         6 . Bobbin winding machine according to  claim 1 , wherein each of the flyer traversing units has two contradirectionally rotatable flyer rotors and a power divider which is coupled to one of the drive wheels wheel. 
     
     
         7 . Bobbin winding machine according to  claim 6 , wherein the power dividers are formed selectively by one of two types of gear which generate an opposite direction of rotation on the flyer rotors. 
     
     
         8 . Bobbin winding machine according to  claim 3 , wherein the flat side of the toothed belt carries a damping textile ply, a basic material of the toothed belt being formed from a polyurethane, and a plurality of steel cords being embedded in the basic material. 
     
     
         9 . Bobbin winding machine according to  claim 8 , wherein the profile side of the toothed belt has a multiplicity of belt teeth with a spacing (T) in the range of 4 mm to 5 mm. 
     
     
         10 . Bobbin winding machine according to  claim 1 , wherein a flat side of the toothed belt carries a damping textile ply, a basic material of the toothed belt being formed from a polyurethane, and a plurality of steel cords being embedded in the basic material. 
     
     
         11 . Bobbin winding machine according to  claim 10 , wherein the profile side of the toothed belt has a multiplicity of belt teeth with a spacing (T) in the range of 4 mm to 5 mm.
