Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Reinigen des Deckelsatzes einer Wanderdeckelkarde gemäss dem Oberbegriff des Patentanspruchs I.The present invention relates to a device for cleaning the lid set of a revolving card, according to the preamble of claim I.

Durch das Schweizerpatent Nr. 501 069 ist eine Anordnung zum Reinigen der Kardendeckel bekannt, bei welcher die Drähte eines Reinigungskamms während ihrer Vorwärts-Schwenkbewegung Fasern und Verunreinigungen aufnehmen. Dabei kommen diese bei der Rückwärts-Schwenkbewegung auf die Spitzen des Kardendeckelbezugs zu liegen. Sie werden von einem mit dem Kamm mitschwingenden Saugtrichter entweder bei dessen Rückwärts-Hub oder beim nächsten Vorwärts-Hub eingesaugt.An arrangement for cleaning the card cover is known from Swiss Patent No. 501 069, in which the wires of a cleaning comb absorb fibers and impurities during their forward pivoting movement. These come to rest on the tips of the card cover with the backward swiveling movement. They are sucked in by a suction funnel that vibrates with the comb either during its reverse stroke or at the next forward stroke.

Der sich über die ganze Breite des Deckelsatzes erstreckende Saugtrichter benötigt für ein einwandfreies Entfemen des Deckelputzes eine sehr grosse Saugleistung, sodass diese Anordnung sich als unwirtschaftlich erweist. Dieser Nachteil soll gemäss vorliegender Erfindung vermieden werden. Diese weist die im kennzeichnenden Teil des Anspruchs I aufgeführten Merkmale auf.The suction funnel, which extends over the entire width of the cover set, requires a very high suction power for the removal of the cover plaster, so that this arrangement proves to be uneconomical. According to the present invention, this disadvantage should be avoided. This has the features listed in the characterizing part of claim I.

Die Erfindung sei nun an Hand verschiedener Ausführungsformen und der Figuren der Zeichnung näher erläutert. In der Letzteren ist

  • Fig. I eine schematische Darstellung der erfindungsgemässen Vorrichtung von der Seite gesehen und sind die
  • Fig. 2, 3 und 4 zur Erläuterung der Wirkungsweise dienende Darstellungen.
The invention will now be explained in more detail with reference to various embodiments and the figures of the drawing. In the latter is
  • Fig. I is a schematic representation of the device according to the invention seen from the side and are the
  • 2, 3 and 4 to illustrate the mode of operation representations.

Fig. I zeigt einen Teil eines Tambours II einer Karde, der in Richtung des Pfeils 12 rotierbar und mit einer Garnitur 13 ausgestattet ist. Die Deckel 14, von denen jeder ebenfalls mit einer Garnitur 15 versehen ist, bilden in ihrer Gesamtheit einen Deckelsatz. Sie sind in Richtung des Pfeils 16 bewegbar.Fig. I shows part of a reel II of a card, which is rotatable in the direction of arrow 12 and equipped with a clothing 13. The covers 14, each of which is also provided with a set 15, form a set of covers in their entirety. They can be moved in the direction of arrow 16.

Eine Bürste 17, welche sich über die ganze Länge der Deckel 14, d.h. über die ganze Breite des Deckelsatzes erstreckt und ungefähr die gleiche Länge wie die Deckel 14 besitzt, ist mittels eines Antriebs 18 um eine Achse 19 schwenkbar. Bezüglich der durch den Pfeil 16 angegebenen Bewegungsrichtung befindet sich hinter der Bürste 17 eine Saugeinrichtung 20. Diese umfasst eine Saugdüse 21 und einen an diese angeschlossenen Schlauch 22 zum Abführen der Saugluft. Ausserdem umfasst sie eine Schiene 23, längs welcher die Düse 21 in der Richtung senkrecht zur Bewegungsrichtung (16) der Deckel, d.h. senkrecht zur Zeichenebene, hin und her bewegbar ist und von welcher sie getragen ist.A brush 17 which extends over the entire length of the lid 14, i.e. Extending over the entire width of the cover set and having approximately the same length as the cover 14 can be pivoted about an axis 19 by means of a drive 18. With regard to the direction of movement indicated by the arrow 16, there is a suction device 20 behind the brush 17. It comprises a suction nozzle 21 and a hose 22 connected to it for discharging the suction air. It also includes a rail 23 along which the nozzle 21 extends in the direction perpendicular to the direction of movement (16) of the cover, i.e. perpendicular to the plane of the drawing, can be moved back and forth and from which it is carried.

Im Betrieb der Karde rotiert der Tambour 12 mit relativ hoher Geschwindigkeit in der durch den Pfeil 12 gezeigten Richtung. Hingegen bewegen sich die Deckel 14 des Deckelsatzes in der Richtung des Pfeiles 16 nur relativ langsam (z.B. 10 cm pro Minute). Dadurch ergibt sich durch das Zusammenwirken der Garnituren 13 und 15 eine Kardierwirkung der auf der Tambourgarnitur 13 herangeführten Textilfasern. Dabei werden kurze Fasern, Fremdkörper, Nissen und dgl. von der Garnitur 15 der Deckel 14 mitgenommen. Daher ist diese im Ansaugbereich mit solchen Materialien gefüllt.When the card is in operation, the reel 12 rotates at a relatively high speed in the direction shown by the arrow 12. In contrast, the lids 14 of the lid set move relatively slowly in the direction of the arrow 16 (e.g. 10 cm per minute). As a result of the interaction of the sets 13 and 15, a carding effect of the textile fibers brought up on the drum set 13 results. Short fibers, foreign bodies, nits and the like are taken away from the clothing 15 of the cover 14. It is therefore filled with such materials in the intake area.

Um die Garnituren 15 der Deckel 14, bevor sie wieder zum Einsatz kommen, zu reinigen, wird die Bürste 17 mittels des Antriebs 18 zu Schwenkbewegungen veranlasst. Die Drähte 24 der Bürste 17 heben dabei das zu entfernende Material aus der Garnitur 15 heraus und legen es als Deckelputz auf die Spitzen der Garnitur. Der Deckelputz wandert mit dem Deckelsatz in Richtung des Pfeiles 16 weiter. Wenn er in den von der Düse 21 überstrichenen Bereich gelangt, wird er von der Düse 21 weggesaugt. Es ist somit ersichtlich, dass zum vollständigen Wegschaffen des Deckelputzes jede Stelle der Oberfläche des Deckelsatzes mindestens einmal abgesaugt werden muss.In order to clean the sets 15 of the covers 14 before they are used again, the brush 17 is caused to pivot by means of the drive 18. The wires 24 of the brush 17 lift the material to be removed from the set 15 and place it on the tips of the set as a cover plaster. The cover plaster moves with the cover set in the direction of arrow 16. When it reaches the area covered by the nozzle 21, it is sucked away from the nozzle 21. It can thus be seen that in order to completely remove the cover plaster, every point on the surface of the cover set must be vacuumed off at least once.

Zur eingehenderen Betrachtung dieses Sachverhalts sei auf die Fig. 2, 3 und 4 verwiesen. Diese zeigen eine Ansicht der Oberfläche des Deckelsatzes in Richtung des Pfeils 25 der Fig. I gesehen, wobei die einzelnen Deckel 14 nicht gezeigt, sondern nur die seitlichen Begrenzungen oder die Seiten 26 des Deckelsatzes gezeichnet sind. Die Richtung der Bewegung der Deckel bzw. des Deckelsatzes ist wiederum durch die Pfeile 16 angegeben. Die Geschwin digkeit der Bewegung der Deckel 14 ist in allen Figuren 2, 3 und 4 als gleich gross vorausgesetzt. Ausserdem zeigt jede der Fig. 2, 3 und 4 in ganz schematischer Weise die Schiene 23. Die drei gezeigten, von den Schienen 23 getragenen Düsen 27, 28 und 29 weisen Düsenöffnungen rechteckigen Querschnitts und verschiedener Längen auf. Die Düse 27 ist die kürzeste und die Düse 29 ist die längste derselben. Die Geschwindigkeit, mit der sich die Düsen senkrecht zur Länge des Deckelsatzes, also zu den Seiten 26 bewegen, sei in allen drei Fig. dieselbe. Es ist aus den Letzteren noch ersichtlich, dass die Längserstreckung der rechteckig geformten Düsenöffnungen parallel zur durch die Pfeile 16 gezeigten Bewegungsrichtung des Deckelsatzes ist.For a closer look at this fact, reference is made to FIGS. 2, 3 and 4. These show a view of the surface of the lid set in the direction of arrow 25 of FIG. I, the individual lids 14 not being shown, but only the lateral boundaries or the sides 26 of the lid set being drawn. The direction of the movement of the cover or the set of covers is again indicated by the arrows 16. The speed of the movement of the cover 14 is assumed to be the same size in all of the FIGS. 2, 3 and 4. Furthermore, each of FIGS. 2, 3 and 4 shows the rail 23 in a very schematic manner. The three shown nozzles 27, 28 and 29 carried by the rails 23 have nozzle openings of rectangular cross section and different lengths. The nozzle 27 is the shortest and the nozzle 29 is the longest thereof. The speed at which the nozzles move perpendicular to the length of the cover set, that is to say to the sides 26, is the same in all three figures. It can also be seen from the latter that the longitudinal extension of the rectangularly shaped nozzle openings is parallel to the direction of movement of the cover set shown by arrows 16.

Die Fig. 2, 3 und 4 zeigen die im Betrieb der Karde von den Düsenöffnungen überstrichenen Flächen. Zur Erklärung und Veranschaulichung sei angenommen, bei Beginn dieser Betrachtung hätten sich gemäss jeder der drei Figuren die Düsen in der Position 30 befunden. Während der ersten Hubbewegung jeder der Düsen von der Position 30 weg über die Breite des Deckelsatzes, führt der Letztere einen Vorschub aus, sodass die Düse am Ende ihrer Hubbewegung sich in der Position 31 befindet. Dabei wurde in allen Fig. die von den Strecken al, a2 begrenzte Fläche überstrichen. Nach dem nächsten Hub, also nach dem beendeten Doppelhub, befinden sich die Düsen 27, 28 und 29 in den Positionen 32 und haben zusätzlich die zwischen den Strecken bl, b2 liegende Fläche überstrichen. Nach dem Doppelhub ist der Vorschub der Deckel bzw. des Deckelsatzes somit gleich z.B. der durch die Strecken al und bl begrenzten Länge der in den Fig. rechten Seiten 26 des Deckelsatzes.2, 3 and 4 show the areas swept by the nozzle openings during operation of the card. For explanation and illustration it is assumed that at the beginning of this consideration, according to each of the three figures, the nozzles were in position 30. During the first stroke movement of each of the nozzles from position 30 across the width of the lid set, the latter performs a feed so that the nozzle is in position 31 at the end of its stroke movement. The area delimited by the distances a1, a2 was covered in all the figures. After the next stroke, that is to say after the double stroke has ended, the nozzles 27, 28 and 29 are in the positions 32 and have additionally covered the area lying between the lines b1, b2. After the double stroke, the feed of the lid or the lid set is the same e.g. the length delimited by the distances al and bl of the right side 26 of the cover set in FIGS.

Bei den weitem Bewegungen werden noch die durch die Strecken cl, c2, die Strecken dl, d2, die Strecken el, e2, die Strecken fl, f2 und die Strecken gl, g2 definierten Flächen überstrichen, womit schliesslich die Düsen 27, 28, 29 in den gezeichneten Positionen angelangt sind. Die Strecken a, c, e und g wurden strichliert und die Strecken b, d, f ausgezogen gezeichnet. Dies geschah nur zum Zweck der Verbesserung der Uebersichtlichkeit.For the further movements, the areas defined by the distances cl, c2, the distances dl, d2, the distances el, e2, the distances fl, f2 and the distances gl, g2 are also covered, which finally the nozzles 27, 28, 29 have reached in the positions shown. The lines a, c, e and g were dashed and the lines b, d, f drawn in solid lines. This was only for the purpose of improving clarity.

Es ist aus Fig. 2 ersichtlich, dass auf der Oberfläche des Deckelsatzes dreieckige Flächen vorhanden sind, die von der Düse 27 nicht überstrichen werden. Das oberste dieser Dreiecke, 33, wird von der in Fig. 2 rechten Seite 26 und den Strecken a2 und bl begrenzt. Das zweitoberste Dreieck 34 wird von der in Fig. 2 linken Seite 26 und den Strecken b2 und cl, das drittoberste Dreieck 35 von der rechten Seite 26 und den Strecken c2, dl usw., begrenzt.It can be seen from FIG. 2 that there are triangular surfaces on the surface of the cover set which are not covered by the nozzle 27. The uppermost of these triangles, 33, is delimited by the right side 26 in FIG. 2 and the distances a2 and bl. The second uppermost triangle 34 is delimited by the left side 26 in FIG. 2 and the distances b2 and cl, the third uppermost triangle 35 by the right side 26 and the distances c2, dl etc.

In Fig. 3 ist die Länge der Düsenöffnung gleich der Länge des Deckelsatzvorschubs während eines Doppelhubs der Düse 28. Es ist aus Fig. 3 ersichtlich, dass unter diesen Umständen von der Düse 28 unüberstrichene, dreieckförmige Flächen verschwunden sind. Falls die Düse 29, wie in Fig. 4 gezeigt, länger ist als die Länge des Deckelsatzvorschubs während eines Doppelhubs der Düse, so sind unüberstrichene Flächen mit Sicherheit vermieden.In FIG. 3, the length of the nozzle opening is equal to the length of the cover set advance during a double stroke of the nozzle 28. It can be seen from FIG. 3 that, under these circumstances, triangular surfaces which have not been covered by the nozzle 28 have disappeared. If, as shown in FIG. 4, the nozzle 29 is longer than the length of the cover set advance during a double stroke of the nozzle, uncoated areas are certainly avoided.

Es ist somit ersichtlich, dass ein Ueberstreichen jeder Stelle der zu reinigenden Deckelsatzoberfläche unter der Bedingung vorhanden ist, dass die Länge der Düsenöffnung mindestens gleich oder grösser ist als der Deckelsatz vorschub während einer Doppelhubbewegung der Düse. Dabei ist zu berücksichtigen, dass, genau genommen, nicht die Grösse der Düsenöffnung, sondern der "Bereich der Saugwirkung der Düse" die massgebende Dimensionierung darstellt. Dies ist, insbesondere für den Geltungsbereich des Patentanspruchs 6, zu berücksichtigen.It can thus be seen that there is a sweep over each point of the lid set surface to be cleaned, provided that the length of the nozzle opening is at least equal to or greater than the lid set advance during a double stroke movement of the nozzle. It must be taken into account that, strictly speaking, it is not the size of the nozzle opening, but the "area of the suction effect of the nozzle" that is the decisive dimension. This is to be taken into account, in particular for the scope of claim 6.

Will man ein mehrmaliges Ueberstreichen jeder Stelle der Deckelsatzoberfläche erhalten, so kann dies durch eine in Richtung des Pfeiles 16 relativ lange Düsenöffnung und durch gegenseitiges Abstimmen des Deckelsatzvorschubs und der Düsenhubzahl erfolgen. Bei einem gegebenen Deckelsatzvorschub müssen die Düsenhubgeschwindigkeit, der Energieverbrauch der Düsen und die Gefahr des Verstopfens derselben gegeneinander abgewogen werden. Es ist vorteilhaft, falls die gegebenen Umstände es zulassen, ein mehrfaches Ueberstreichen jeder Stelle des Deckelsatzes durch die Düse herbeizuführen, wobei bis zu einem fünffachen Ueberstreichen gegangen werden kann.If you want to get a repeated sweep of each point on the cover set surface, this can be done by a relatively long nozzle opening in the direction of arrow 16 and by mutual coordination of the cover set feed and the number of nozzle strokes. For a given lid set feed rate, the nozzle lift speed, the energy consumption of the nozzles and the risk of them clogging must be weighed against each other. It is advantageous if the given circumstances allow a multiple sweep of each point of the cover set through the nozzle, it being possible to sweep up to five times.

Eine sehr gute Arbeitsweise ergab sich bei einer Anordnung mit einer Deckelgeschwindigkeit von ca. 10 cm pro Minute und 5 bis 10 Doppelhüben der Düse pro Minute.A very good method of working was obtained with an arrangement with a lid speed of approx. 10 cm per minute and 5 to 10 double strokes of the nozzle per minute.

Wie bereits erwähnt, ist die Düsenöffnung vorteilhafterweise von rechteckiger Form. Es kann aber auch eine elliptische Form in Betracht gezogen werden. Die Längserstreckung der Düsenöffnung ist parallel zur durch den Pfeil 16 gezeigten Bewegungsrichtung der Deckel 14. Eine vorteilhafte Ausgestaltung einer rechteckigen Düsenöffnung besteht darin, dass das Verhältnis der Länge der Düsenöffnung zu deren Breite einen zwischen 3 und 7 liegenden Wert aufweist. In einer Ausführungsform, welche sehr gute Resultate ergab, war die rechteckige Oeffnung 12 cm lang und 2,5 cm breit.As already mentioned, the nozzle opening is advantageously of rectangular shape. However, an elliptical shape can also be considered. The longitudinal extension of the nozzle opening is parallel to the direction of movement of the cover 14 shown by arrow 16. An advantageous embodiment of a rectangular nozzle opening consists in that the ratio of the length of the nozzle opening to its width has a value between 3 and 7. In one embodiment, which gave very good results, the rectangular opening was 12 cm long and 2.5 cm wide.

In Bezug auf die Möglichkeit eines Verstopfens der Düse zeigt es sich, dass diese Gefahr wesentlich reduziert wird, wenn die Düse an ihrem bezüglich der Bewegungsrichtung der Deckel 14 vordern Teil mit einer Abschrägung versehen ist, welche gegen das vorderste Ende der Düse hin nach oben, d.h. vom Deckelsatz weg, verläuft. Diese Abschrägung ist in Fig. 1 mit 36 bezeichnet. Eine gute Arbeitsweise wurde bei einem Abstand der Düsenöffnung von ca. 3 mm von den Spitzen der Deckelgarnitur, erhalten.With regard to the possibility of clogging of the nozzle, it can be seen that this risk is substantially reduced if the nozzle is provided on its front part with respect to the direction of movement of the cover 14 with a bevel which is directed upwards towards the foremost end of the nozzle, ie away from the lid set. This bevel is designated 36 in FIG. 1. A good working method was obtained with a distance of the nozzle opening of approx. 3 mm from the tips of the cover set.
