Most of such drawing rollers have and are installed in resting position and driven upper feeding roller, and have and be installed in resting position and driven lower payment roller.Upper feeding roller is assigned to movably and the upper feeding roller be loaded, and the fibre bundle introduced is sandwiched between upper feeding roller and lower feed roller.Fibre bundle and upper feeding roller all to be carried secretly by lower feed roller by being frictionally engaged.Similarly, lower payment roller is assigned to movably and the upper payment roller be loaded, and the fibre bundle be discharged also is sandwiched between payment roller and lower payment roller.Fibre bundle and upper payment roller are also carried secretly by lower payment roller by being frictionally engaged at this.Rotate with the peripheral speed more much higher than lower feed roller the drawing-off that this fact realizes fibre bundle by lower payment roller, the fiber of fiber sliver is opened along transporting direction in draw zone.
In order to realize the even drawing-off of fibre bundle and avoid the defectiveness drawing-off of fibre bundle, fiber guiding device is arranged on (such as in DE362211) in the draw zone of drawing rollers.Therefore the fiber guiding device described in DE362211 is made up of fiber guide band and fiber guide element, wherein between fiber guide band and fiber guide element, guides fibre bundle.The downside that the fiber guide band being implemented as continuous band is arranged on drawing rollers extends around stationary yaw element and lower feed roller.When the drawing rollers described in DE362211, compared to such traditional drawing rollers, independent roller drives fiber guide band, and this independent roller to be arranged on below lower feed roller and to be connected to fiber guide band by being frictionally engaged.
The fiber guide element being implemented as rigid plate form is arranged on the upside of drawing rollers.Fiber guide element to be sat idly on fiber guide band with himself weight and therefore fibre bundle is compressed this band.In order to increase pressing effect, additional spring force is used to act on fiber guide element by spring.Fiber guide element is attached to the framework of drawing rollers together with spring by means of linkage, make fiber guide element can be taken away draw zone so that such as in order to clean drawing rollers.A significant drawback of such drawing rollers is, takies the large quantity space in drawing rollers, so fiber guiding device has somewhat complex design due to fiber guiding device.Another shortcoming of drawing rollers may be the following fact: spring stands fair wear and tear, therefore presses effect and weakens in time.This quality for drafted fibre bundle has negative effect.
Summary of the invention
Therefore, target of the present invention improves the drawing rollers of the above-mentioned type, even quality when making fiber guiding device have more simply design compared to prior art and guarantee the drawing-off of fibre bundle.
In the context of the present invention, fibre bundle is understood to be the slim-lined construction of single fiber, and its length is far shorter than the length of this structure.The fiber sliver non-twist in fact that fibre bundle can be produced specifically on carding machine, combing machine or drawing frame.This fiber sliver is processed to form the rove having protectiveness and twist with the fingers on the flyer spindle being equipped with drawing rollers.Similarly, fibre bundle can be the rove being equipped with protectiveness to twist with the fingers, and it is processed to the yarn with sth. made by twisting on spinning machine, and this spinning machine is equipped with the drawing rollers such as on ring spinning frame.
Drawing rollers according to the present invention are suitable for the spinning preparation machine of such as flyer spindle or drawing frame and both spinning machines of such as ring spinning frame particularly, and when they have multiple work station, each work station produces a rove or yarn.Also can expect that multiple fibre bundle is supplied to drawing rollers at a work station place and by drawing-off together.
In addition, draw zone is understood as that it is region between the clamping line that two adjacent rollers at drawn fiber bundle place are right.Here bottom roll is the roller in stationary bracket, and top roller is the roller in movable support compressing bottom roll.Top roller is arranged on above its corresponding bottom roll usually.But, also can expect the drawing rollers that wherein fibre bundle substantially vertically extends.In this case, the top roller of roller centering and bottom roll can be disposed side by side.Fiber guide band is continuous structure, and it turns round around deflecting element, makes it at least major part of draw zone, contact fibre bundle (observed by along direct of travel), and as one man moves with fibre bundle.
This target is implemented by following firm basis the present invention: fiber guide element is implemented as elastic spring element, and it has the fiber guide surface for guiding fibre bundle.
At operating position, there is the elastic spring element contact fiber guide band on fiber guide surface and gone out its resting position by fiber guide belt deflector.Due to its spring performance, elastic spring element is because this deflection experience is along the restoring force in its resting position direction.In this way, directed between fiber guide band and fiber guide surface fibre bundle is pressed against fiber guide band.Compared to prior art, the pressing force pointed to across with the transporting direction of fibre bundle is produced by the elastomeric spring effect of spring element itself.In addition, elastic spring element achieves following result: fibre bundle directed between fiber guide band and fiber guide surface utilizes even pressing force to be pressed against fiber guide band.Therefore, drafted fibre bundle accurately to be guided in fiber guiding device, this contributes to the even drawing-off of fibre bundle.Test verified, when fiber guide band be stretched in draw zone and turn round around deflecting element be fixedly mounted in draw zone time, realize enough pressing forces of elastic spring element.This achieve following result: the fiber guide surface of elastic spring element is with its full recovery power contact fiber guide band.That deflecting element is cage or bridge at the top roller of feed roller centering or bottom roll upper rotary according to fiber guide band.In order to realize the accurate guiding of fibre bundle between fiber guide band and the fiber guide surface of elastic spring element, also advantageously verified, when the forming element at fiber guide band stretching (making elastic spring element accurately contact fiber guide band) place is arranged between deflecting element and fiber guide band.Because fiber guide element is as the design of elastic spring element, the design of drawing rollers is simplified, this is because compared to prior art, eliminates the additional springs used for generation of pressing force.In addition, due to its simplicity, elastic spring element can be manufactured cheaply.
