Definitions
- the invention relates to a thread delivery device of the type specified in the preamble of claim 1.
- the processed thread material namely permanently produces impurities such as fluff, dust, pieces of fiber and the like, which have the tendency, inter alia, to also enter the gap area, settle there and gradually move from there into the inside of the thread delivery device, which can lead to malfunctions. Contaminants in particular adhere to the inside of the ring until a coherent layer of contaminants builds up.
- the invention is based on the object of improving a thread delivery device of the type mentioned at the outset in a structurally simple and cost-effective manner in such a way that malfunctions due to contamination deposits are largely avoided.
- the catch element fulfills two functions. First of all, the build-up of a thick impurity layer on the inside of the ring is counteracted because the catch element forms a periodic irregularity during the relative movement as a disturbing factor in the build-up of an impurity layer, which counteracts the deposition of impurities from the start. Furthermore, there is surprisingly a mechanical effect of the catching element on impurities on the inside of the ring. Due to the different levels of centrifugal force on the contaminants, these expand inwards when the ring is stationary or at low speed until they collide with the catching element and are at least partially torn loose. The contaminants that are torn loose take the path of least resistance and fly out of the opening of the gap area.
- the breakaway surface represents a mechanical and a flow obstacle for contamination. If the breakaway surface is undercut, tufts of lint get caught particularly easily, as a result of which contaminants are torn off from the inside of the ring and the inside is stripped off before the impurities fly out of the gap area.
- a feed force is exerted on torn-off or just arriving impurities which conveys them outward from the gap area.
- the deflection surface removes the dirt like a plow, also supported by turbulence and air cushions.
- the embodiment according to claim 6 is also important, because already deposited impurities relax inward into the relaxation zone when the centrifugal force decreases and are torn loose when the ring accelerates.
- the embodiment according to claim 7 is structurally simple.
- the catch element can already be molded on during the manufacture of the housing flange. However, it is also conceivable to retrofit the catch element, for example to glue it on, to screw it on or to fasten it in some other way.
- the structuring on the surface of the projection causes an additional disturbance in the build-up of an impurity layer.
- the embodiment according to claim 10 is structurally simple and effective.
- the depression at the same time creates the breakaway surface or the rejection surface for each direction of rotation, while the bottom of the depression creates the necessary relaxation zone.
- a depression with the design according to claim 13 has a similarly favorable effect.
- a particularly advantageous embodiment is set out in claim 14.
- the edge bead of the rear winding protective trough is used for an additional task, since it is entrusted with the deepening for the loosening and removal of impurities.
- the protective channel has the effect of a rear winding, in which the thread reaches behind the ring, to prevent the thread from penetrating into the interior of the thread delivery device.
- FIG. 1 shows a schematic longitudinal sectional view of a first embodiment of a thread delivery device
- FIG. 2 shows a part of a longitudinal section of another embodiment of a thread delivery device
- FIG. 3 shows a part of the housing of the thread delivery device of FIG. 2 with differently designed catching elements
- FIG. 5 shows a view similar to that of FIG. 3 for the housing flange of the thread feeding device according to FIG. 1, and
- FIG. 6 shows a section in plane IV in FIG. 5.
- a thread delivery device F according to FIG. 1 (longitudinal section with hatching only for components that are important for the invention) has a stationary housing 1 to which a longitudinal arm 2 is attached.
- the housing 1 is fixed with a holder 3.
- a drive shaft 4 is rotatably mounted, for example with roller bearings 17, which can be driven in rotation by means of an electric motor 5.
- a storage drum 6 is located on the shaft 4 by means of bearings 18 rotatably supported, which is prevented from rotating with the shaft 4 by stationary magnets 15 and 16 arranged in the housing 1 and in the storage drum 6 and aligned with one another (stationary storage drum).
- a thread eyelet 7 is provided on the extension arm 2 for the thread drawn overhead from the storage drum 6.
- a winding element 9 (winding tube) is attached, through which the thread passing through the hollow shaft 4 in its rear region is deposited in turns on the storage drum 6.
- the winding element 9 can be integrated in a conical disk 10 and has an approximately cylindrical edge 11.
- the housing 1 is provided with a stationary housing flange 12 which engages under the edge 11 with an overlap Ü and defines a gap region S which is axially open to the left.
- a rear winding protective groove 13 ' is formed in the approximately cylindrical peripheral surface 13 in the housing flange 12, which ends with an edge bead 14 which engages under the ring 11.
- At least one catch element C is provided in the area of the edge bead 14 and the outer circumference 13 of the housing flange 12, which is explained in detail with reference to FIGS. 5 and 6.
- the shaft 14 which can be driven by the electric motor 5, carries the winding element 9 and the storage drum 6, which is prevented from rotating by means of the permanent magnets 15, 16. If necessary, an annular thread brake works together with the storage body 6.
- the outer circumference 13 of the housing flange 12 is approximately cylindrical and engages under the edge 11 of the disk 10 of the winding element 9 from the inside Rolling bearings 17 are mounted in the housing 1, while the storage body 6 is mounted on the shaft 4 with rolling bearings 18.
- At least one catch element C is provided in the gap area S defined between the edge 11 and the peripheral surface 13 of the housing flange 12, which will be explained in more detail with reference to FIGS. 3 and 4.
- a thread measuring device could also cooperate with the storage drum 6. Furthermore, the storage drum 6 could be driven in rotation and then define the winding element 9, the same interaction being present between the edge 11 and the housing flange 12 as shown in FIGS.
- the housing flange 12 of the housing 1 carries on its approximately cylindrical outer circumference 13 at least one catch element C in the form of a projection 19, which is expediently formed in one piece with the housing flange 12 and is between 1 and 5 mm high is.
- the projection 19 is located in the region of the overlap Ü between the ring 11 shown in dashed lines and the housing flange 12.
- the projection 19 shown in the middle of FIG. 3 has front and rear deflecting surfaces 20, 20 ', each with a Loose surface 21 is summarized.
- At least the breakaway surface 21 extends approximately radially to the axis of the housing 1. It may even be undercut.
- Several such triangular projections 19 can be provided along the circumference of the housing flange 12. If the ring 11 is always driven only with the same direction of rotation A or B, then a breakaway surface 21 or a deflecting surface 20 or 20 'combined with a breakaway surface 21, which is opposite to the direction of rotation A or B, is sufficient.
- a catch element of a projection 19 which is longer in the circumferential direction is indicated, which carries a deflecting surface 20 or 20 ', which is combined with an approximately radial breakaway surface 21.
- the outer circumference of the projection 19 could, as indicated at 25, be structured, e.g. cross-ribbed or equipped with saw teeth.
- the leftward tip of the middle projection 19 and the left-hand peripheral edge 21 of the two other projections close approximately with the contour of the ring 11 or protrude to the left above it.
- a simplified embodiment is indicated, in which the catching element C only as a simple axial rib or pin Like projection 19 is formed, which defines breakaway surfaces 21 or deflecting surfaces 20 on both sides. 3 and 4, a relaxation zone Z is provided in the direction of rotation in front of the catching element, in which the gap width is larger than directly above the catching element C.
- the upper side of the fan element C lies on the inside 11a of the edge 11 ⁇ according to the distance.
- edge 11 rotates in the indicated direction of rotation in FIG. 4, then impurities can only be deposited on the inside Ila with a small thickness because the breakaway surface 21 immediately tears away or pushes away further impurities. If, during the fast-running edge 11, impurities have accumulated on the inside 11a and if the edge 11 comes to a standstill or a slower rotary movement, the elastic impurities relax into the relaxation zone Z before they subsequently leave the upstanding breakaway surface 21 be torn off. A tuft of lint getting caught on the breakaway surface 21 sweeps along the inside 11a until all impurities have been torn loose and then fly outward out of the gap area S. If the breakaway surface 21 is combined with a deflecting surface 20, then the removal of contaminants is further favored, as indicated in FIG. 3.
- the catch element C is formed in an edge bead 14 of a back-winding protection channel 13 'in the form of a depression N, which is used, for example, for the direction of rotation A of the Ring 11 defines the breakaway surface 21 with its approximately radial boundary surface.
- the boundary surfaces are inclined (angle ⁇ ) so that the boundary surface intended for the direction of rotation A defines both a breakaway surface 21 and a deflecting surface 20 for contaminants which are conveyed to the outside.
- the groove 13 ' serves to pick up and collect thread windings which have reached the storage drum if the winding is faulty and are not intended to enter the gap area S.
- the boundary surfaces 23, 24 of the recess N can each define a breakaway surface 20 and a deflecting surface 21, expediently very sharp-edged, for example for the direction of rotation A, the base 22 of the recess N the relaxation zone Z forms.
- the depression N in the bead 14 is approximately rectangular. Their length in the circumferential direction is between 7 and 8 mm, their depth can be about 4 to 5 mm.
- the boundary surfaces 24 and 23 can also be undercut to form hooks. An inclination of the boundary surfaces as in FIG. 5, below, is also possible.
- a plurality of projections 10 or depressions N are expediently distributed in the circumferential direction of the housing flange 12.
