Definitions
- the invention relates to a ring spinning spindle with a separating device to separate a spider thread when pulling off the cop the cutting and cams includes, the cams the Radially project sections in sections and also in Extend in the direction of the axis of the ring spinning spindle. This stretching the cam in the direction of the axis of the ring spinning spindle serves to protect against injury when touching the spindle in the area of the cutting knife and to prevent sliding of the piecing thread around the perimeter of the separator and adjusts essential feature of the same.
- Such separation devices are from DE 42 37 475 A1 and DE 40 15 707 C2 known. These separators are the Arranged cams on a separate part from the cutting knife, the is usually designed as a pressure or injection molded part. The devices therefore require the production of two parts and their Assembly. This training is expensive and caused because of it the cutting knife is a wearing part that sometimes must be replaced, not inconsiderable spare parts costs.
- the object of the invention was to provide a simpler structure and thus a more cost-effective production of such a separation device to reach.
- the sheet metal part forming the separating device in Is pulled towards the axis of the ring spinning spindle in it both in a plane and in a conical surface or cutting edges lying in a cylinder jacket as well as in Cams extending in the direction of the axis of the ring spinning spindle shape.
- the one-piece of the separating device has in addition cost-effective production has the further advantage that it Avoids gaps in common multi-part separators, Experience has shown that thread pieces can pull into them, which are difficult or impossible to remove are.
- the Separating device forming, stamped, preferably still flat Sheet metal part cutting introduced (e.g. ground, punched, embossed) and the teeth that remain between them in the direction the axis of the spindle and thus formed into cams.
- This Cams can then be given a certain contour, be rounded off, for example.
- This embodiment is particularly suitable for separators with one level To cut. However, it is also possible to cut in a beforehand Insert a pot-shaped sheet metal part.
- the cams are against the axis of the ring spinning spindle are inclined so that they are at their free ends have a greater distance from the spindle axis than at the connecting them with the ring spindle and their the Cutting facing inner surfaces moved away from these cutting edges are threads or pieces of thread, such as when pulling of the cop are pulled behind the cams through which Centrifugal force thrown off again while the ring spinning spindle was running.
- Cutting devices made of very thin sheet metal offer the Advantage, little machining to sharpen the Cutting or low forces for shaping the cutting edges and to require equally low forces for the forming process.
- Around sufficient strength even with such separators at least the cam, possibly also the entire separating device
- the cams can be reached by bending back the Rag from which they are formed against themselves (Flanging) to be doubled. This also as a forming process feasible doubling can extend over the area of the cams out into the area of the ring body of the separating device extend.
- a preferred embodiment of the invention for a Separating device the cutting of which in a conical or cylindrical Area is arranged by a crown cap marked not dissimilar fitting that the cams forming projections and recesses containing the cutting edges has, the recesses to be cut by scraping, for example are sharpened.
- a separation device has none Undercuts behind which threads can get caught.
- Such a separating device can also be made by so-called drums be deburred and rounded with emery stones without the recessed cutting edges reached by the emery bodies and could be made blunt.
- the separation device without cutting as in a molding process in a negative mold part of the desired spatial shape be.
- This can be a sintering of powder metal or a pressure or injection molding process. It has shown that with these manufacturing processes, the cutting can be achieved in the required sharpness and hardness.
- a such part has the advantage that it is in a single Manufacturing process is producible. At most they can Cutting in a preferably galvanic post-processing step subject to additional sharpening.
- a separator The essential components of a separator are Cut and the cams. If a separator above further components such as behind recesses in the upper part of the spindle snapping noses, guide bushes for functionally appropriate Holders of the separation devices and the like, understands it is that these other components when pulling the the separating device forming sheet metal part can be molded.
- FIG. 1 shows the essentials for understanding the invention Parts of a common ring spinning spindle 1. It comprises a rotatable spindle upper part 3 mounted in a lower spindle part 2, on which a sleeve 4 is attached.
- the upper spindle part 3 will by a spindle spindle 5, not shown in detail arranged drive, for example in the form of a tangential belt in Rotation offset.
- On the sleeve 4 is by means of a Spinning ring 6 rotating rotor 7 from a thread 8, the a drafting device, not shown, via a thread guide 9 runs, a winding 10 built.
- Sleeve 4 and winding 10 form a cop 11.
- the ring spinning spindle 1 is shown in a position in which after finishing a cop 11 of the spinning ring 6 down guided and in an underwind area 12 of the upper spindle part 3 a winding 13 has been formed. This runs from the winding of the cop 11 a spinning thread 14 for winding 13. This spinning thread 14 must be separated when pulling out a cop become. To facilitate this and pulling thread To prevent from underwinding 13 is between the underwinding area 12 and the cop 11 on the upper spindle part 3 Separating device 15 arranged with a separating knife, on the Cutting edge of the spinning thread 14 is present when the cop is pulled off pressed and cut in the process.
- the separating device 15 is an embodiment variant 2 and 3 of a flat steel disc from the outside edge by means of an in Fig. 3 indicated disc-shaped grinding wheel 16 one after the other sharp cutting edges 17 are ground between them these cutting-edge tabs 19 remain, of which two dashed lines are indicated on the side of the grinding wheel. These tabs 19 are then still in a pulling process bent over at the bottom so that they protrude the cutting edges 17 and one substantial extension in the direction of the axis of the ring spinning spindle Form 1 having cams 18. You pose this way both protection against touching the cutting edges as well Leading edges for the spinning thread.
- FIG. 4 and 5 show an embodiment in which the outer edge the steel disc from which the separator 15 is made is, preferably by punching into differently shaped, lobes 19 and 20 indicated by dashed lines at one point is formed, from which on the one hand the cutting edges 17 and on the other hand the cams 18 are formed.
- the separating cut goes 21 between the tabs 19 and 20 up to an imaginary dash-dotted circle 22, from which the cams 18 the plane of the cutting edges 17 are to be bent out.
- the for the Cutting 17 provided tabs 19 are, for example, on the in Fig. 3 indicated way sharpened.
- the one for the cams 18 provided tabs 20 are pulled towards the axis of the ring spinning spindle in the one shown in FIG. 4 Curved up and down.
- the contour of the cams 18 can with this production method by appropriate punching dies can be designed arbitrarily.
- the cams 18 '' can be reached after another Proposal of the invention according to FIG. 8 by bending back their correspondingly longer flaps 20 doubled become. This deformation can also be caused by a pulling process in the direction of the axis of the ring spinning spindle.
- the two Layers of the tabs 20 forming the cams 18 ′′ can be with one another glued, soldered or otherwise firmly connected and to be additionally stiffened.
- the cutting edges 17 'as in FIGS. 6 and 7th together by scraping with a lifting movement Tool are manufactured.
- the cams 18 ′′ are through multiple bending of the tabs 20 formed. As can be seen bending the tabs 20 offers the possibility of the cams to train in various forms. Those lying on one level Cutting edges 17 'of FIG. 9 can also be angled as in FIG. 8 and then lie in the surface of a cone or a cylinder.
- the separating devices of FIGS. 6 to 8 have their inner diameter a collar 28 by means of which the separator is guided exactly on the upper part of the spindle.
- This covenant 28 can be molded on when pulling the separator.
- this collar 28 also have a nose 29 which behind a groove in Upper spindle part 2 occurs and the separating device on the Specifies the upper part of the spindle.
- a separator about a shape as shown in Fig. 6 and 7, can also be achieved by a non-cutting molding process can be achieved in a negative form.
- This can be a pressure or injection molding process or around sintering powder metal act in a corresponding divisible form.
- the Rule are one in this way in one step manufactured separator no further (post) operations required. In some cases it can be advantageous to sharpen the cutting edges 17, 17 '. This offers itself especially a galvanic operation.
