Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Reinigen des Deckelsatzes einer Wanderdeckelkarde gemäss dem Oberbegriff des Patentanspruches 1.The present invention relates to a device for cleaning the set of covers of a revolving card, according to the preamble of claim 1.

In den Karden nimmt der auf seiner zylindrischen Oberfläche mit Nadeln versehene Tambour bei seiner Rotation das ihm zugeführte Fasermaterial mit sich und bewegt dieses zwischen seiner Garnitur und derjenigen der Deckel des sich normalerweise in der entgegengesetzten Richtung bewegenden Kardendeckelsatzes. Dadurch werden die Fasern des Fasermaterials parallelisiert. Zusätzlich erfahren sie eine Reinigung. Verunreinigungen wie Schalenteile, Nissen und dergleichen sammeln sich dabei in den Garnituren der Kardendeckel an. Diese Garnituren müssen daher ihrerseits während des Betriebs der Karde laufend wieder gereinigt werden. Dies erfolgt an einer sich ausserhalb der Kardierzone befindlichen Reinigungszone mittels in die Garnitur der Deckel eintauchenden Bürsten.In the cards, the reel, which is provided with needles on its cylindrical surface, takes with it the fiber material fed to it and moves it between its clothing and that of the cover of the card cover set, which normally moves in the opposite direction. The fibers of the fiber material are thereby parallelized. They also undergo cleaning. Contaminants such as shell parts, nits and the like accumulate in the card cover sets. These sets must therefore be continuously cleaned again during the operation of the card. This takes place in a cleaning zone located outside the carding zone by means of brushes immersed in the clothing of the cover.

Gemäss dem CH-Patent Nr. 501 294 wird der Deckelputz mit einer schwingenden Bürste aus der Garnitur der Deckel gelöst und gelangt als zusammenhängendes Vlies in die Bewegungsbahn eines schwingenden Kammes. Dieser sticht mit seinen Nadeln in das Vlies ein und trennt Streifen von der Vliesbahn ab, welche bei senkrechter Lage der Nadeln des schwingenden Kammes von diesem abfallen. Eine rotierende Bürste reinigt zusätzlich die Deckelgarnitur von Schalen und dergleichen.According to Swiss Patent No. 501 294, the cover plaster is released from the set of covers with a swinging brush and enters the path of movement of a swinging comb as a coherent fleece. This pierces the fleece with its needles and separates strips from the fleece web, which fall off the vibrating comb when the needles of the vibrating comb are in a vertical position. A rotating brush also cleans the lid set from bowls and the like.

Diese Reinigungsvorrichtung besitzt den Nachteil, dass die Reinigung der Deckelgarnitur nicht mit genügender Gründlichkeit erfolgt und die Verunreinigungen nicht in genügendem Masse aus der Garnitur herausgeschafft werden.This cleaning device has the disadvantage that the cover set is not cleaned with sufficient thoroughness and the impurities are not removed from the set to a sufficient extent.

Im weiteren ist aus der Deutschen Patentschrift Nr. 52 845 eine Vorrichtung zum Reinigen des Deckelsatzes gemäss Oberbegriff des ersten Anspruches bekannt.Furthermore, a device for cleaning the lid set according to the preamble of the first claim is known from German Patent No. 52 845.

Dabei ist der Träger der Reinigungsbürste mittels einer Nockenführung in Richtung gegen den Deckelsatz und in entgegengesetzter Richtung linear bewegbar, sowie mittels einer zweiten Nutenführung schwenkbar, so dass die Reinigungsbürste auf Grund der beiden Nutenführungen in der Lage ist, in der einen Schwenkrichtung in die Garnitur der Dekkel einzudringen und in der Rückwärtsbewegung daran vorbeizuschwenken.The carrier of the cleaning brush can be moved linearly by means of a cam guide in the direction against the cover set and in the opposite direction, and can be pivoted by means of a second groove guide, so that the cleaning brush is able to swivel into the set in one direction due to the two groove guides Penetrate lid and swing past it in the backward motion.

Der Nachteil besteht jedoch darin, dass durch die für die genannte lineare wie auch für die genannte Schwenkbewegung je ein Hebel notwendig ist, welcher durch die Nutenführungen bewegt werden muss, was einerseits die Möglichkeit ausschliesst zusätzlich die erfindungsgemässe translatorische Bewegung und andererseits ebenso die Möglichkeit ausschliesst die Eindringtiefe der Bürste in die Garnitur variabel zu gestalten, was als weitere erfindungsgemässe Ausführungsform später beschrieben und beansprucht ist.The disadvantage, however, is that a lever is required for the linear as well as for the mentioned pivoting movement, which has to be moved by the groove guides, which on the one hand excludes the possibility of the translational movement according to the invention and on the other hand also excludes the possibility of To make the depth of penetration of the brush variable in the set, which is described and claimed later as a further embodiment according to the invention.

Gemäss vorliegender Erfindung sollen die vorgenannten Nachteile durch die im kennzeichnenden Teil des ersten Anspruches aufgeführten Merkmale vermieden werden.According to the present invention, the aforementioned disadvantages are to be avoided by the features listed in the characterizing part of the first claim.

Der Vorteil unserer Erfindung besteht in der wesentlich einfacheren und leichteren Bedienbarkeit sowie in der Flexibilität um gute technologische Resultate zu erhalten.The advantage of our invention is that it is much easier and easier to use and that it is flexible enough to get good technological results.

Gleiche Teile sind in den Figuren mit gleichen Bezugszeichen versehen.Identical parts are provided with the same reference symbols in the figures.

In Fig. 1 ist eine rotierbare Trommel 11 einer Karde gezeigt, auf deren zylindrischer Mantelfläche Nadeln 12 angebracht sind. Ein Wanderdeckelsatz umfasst einzelne Deckel 13, von denen jeder mit einer Garnitur 14 versehen ist. Der Wanderdeckelsatz bewegt sich im Betrieb relativ langsam in Richtung des Pfeils 15. Eine sich über die ganze Breite der Karde erstreckende Bürste 16 ist mit einer Welle 17 fest verbunden und mit dieser um deren Achse 18 zwischen den strichliert gezeichneten Positionen A und B und über die Position C, wie durch den Doppelpfeil 19 angedeutet, schwenkbar. Die Welle 17 erstreckt sich zwischen zwei zu ihr senkrechten Platten 20, von denen die eine Platte sichtbar ist. Sie wird von den Platten 20 getragen. Die letzteren tragen ausserdem einen Kamm 21. Die Platten sind durch nicht gezeigte Bauteile zu einer Einheit zusammengebaut, welche einen Träger für die Welle 17 bildet. Deshalb soll das Bezugszeichen 20 sowohl die Platten als auch den Träger bezeichnen. Schliesslich ist noch eine Trägerstange 22 vorgesehen, welche am Kardengestell befestigt ist und zum schwenkbaren Tragen der Platten 20 dient. Ueberdies sind diese Platten 20 von einem Ende einer Zylinder-Kolbeneinheit 23 getragen, deren anderes Ende an einer Befestigungsstelle 24 am Kardengestell befestigt ist. Der Kolben der Einheit 23 ist mittels eines Druckfluidums in der einen Richtung und mittels einer Druckfeder in der anderen Richtung bewegbar. Das Druckfluidum wird über ein Ventil 25 in den Zylinder eingeführt. Das Ventil 25 ist mittels eines nicht gezeigten, an sich bekannten Steuermittels steuerbar.In Fig. 1, a rotatable drum 11 of a card is shown, on the cylindrical surface of which needles 12 are attached. A traveling cover set comprises individual covers 13, each of which is provided with a clothing 14. The revolving cover set moves relatively slowly in the direction of arrow 15 during operation. A brush 16 that extends over the entire width of the card is included a shaft 17 firmly connected and with this about its axis 18 between the dashed positions A and B and the position C, as indicated by the double arrow 19, pivotable. The shaft 17 extends between two plates 20 perpendicular to it, one plate of which is visible. It is carried by the plates 20. The latter also carry a comb 21. The plates are assembled to form a unit by components, not shown, which forms a carrier for the shaft 17. Therefore, reference numeral 20 is intended to designate both the plates and the carrier. Finally, a support rod 22 is also provided, which is fastened to the card frame and is used for pivotably supporting the plates 20. In addition, these plates 20 are carried by one end of a cylinder-piston unit 23, the other end of which is fastened to a fastening point 24 on the card frame. The piston of the unit 23 can be moved in one direction by means of a pressure fluid and in the other direction by means of a pressure spring. The pressure fluid is introduced into the cylinder via a valve 25. The valve 25 can be controlled by means of a control means, which is not shown and is known per se.

Im Betrieb bewegt sich der Deckelsatz langsam (z.B. 25 cm/Min.) in der durch den Pfeil 15 gezeigten Richtung. Die Bürste 16 führt, wie durch den Doppelpfeil 19 angedeutet, Schwenkungen (z.B. 40/Min.) aus. Die Schwenkungen bewegen sich in einer (der Garniturreinigung dienenden) Reinigungsbewegung von der Position A über die Position C zur Position B und in einer Rückbewegung wieder zur Position A zurück. Die Position C repräsentiert die Stelle, an der die Garnituren 14 der Deckel 13 gereinigt werden, also die Deckelreinigungsstelle. Da diese mit der Position C zusammenfällt, ist sie im Folgenden ebenfalls mit dem Bezugzeichen C bezeichnet. Um die von der Bürste 16 mitgenommenen Materialteilchen wieder aus der Bürste zu entfernen, wird diese bei ihrer Schwenkbewegung durch einen Kamm 21 durchbewegt.In operation, the lid set moves slowly (eg 25 cm / min.) In the direction shown by arrow 15. As indicated by the double arrow 19, the brush 16 carries out swivels (for example 40 / min.). The swivels move in a cleaning movement (serving to clean the clothing) from position A via position C to position B and in a return movement back to position A. Position C represents the point at which the clothing 14 of the cover 13 is cleaned, that is to say the cover cleaning point. Since this coincides with the position C, it is also designated with the reference symbol C below. To remove the material particles carried by the brush 16 out of the brush remove, this is moved through its comb through a comb 21.

Im Betrieb wird die Einheit 23 im Rhythmus der Schwenkbewegungen der Bürste 16 betätigt. Durch Oeffnen des Ventils 25 wird durch das Druckfluidum auf den Kolben der Einheit 23 ein Druck ausgeübt, wodurch sich dieser Kolben, unter Zusammendrücken der in der Einheit 23 vorhandenen Druckfeder, in Richtung von der Befestigungsstelle 24 weg bewegt. Dabei werden die Platten 20 um die Trägerstange 22 im Gegenuhrzeigersinn geschwenkt. Es kann für jede der Platten 20 eine ein Antriebsmittel bildende Einheit 23, oder für beide Platten 20 eine diesen gemeinsame, ein Antriebsmittel bildende Einheit 23 vorgesehen sein. Da die Welle 17 von den Platten oder dem Träger 20 getragen wird, vergrössert sich bei dieser Schwenkung der an der Deckelreinigungsstelle C vorhandene Abstand der Bewegungsbahn der Bürste 16 vom Deckelsatz, d.h. die Platten 20 und damit die Bewegungsbahn der Bürste 16 werden in eine an der Reinigungsstelle C vom Deckelsatz entfernte Position gebracht.In operation, the unit 23 is operated in the rhythm of the pivoting movements of the brush 16. By opening the valve 25, a pressure is exerted on the piston of the unit 23 by the pressure fluid, as a result of which this piston moves away from the fastening point 24 while compressing the compression spring present in the unit 23. The plates 20 are pivoted about the support rod 22 counterclockwise. A unit 23 forming a drive means can be provided for each of the plates 20, or a unit 23 forming a drive means common to both plates 20. Since the shaft 17 is carried by the plates or the carrier 20, the distance between the movement path of the brush 16 and the set of covers, i.e. the plates 20 and thus the path of movement of the brush 16 are brought into a position at the cleaning point C from the set of covers.

Das Ventil 25 der Einheit 23 ist durch ein an sich bekanntes und daher nicht gezeichnetes Steuermittel betätigbar. Dieses kann beispielsweise auf der Basis einer elektrischen Schaltung beruhen. Durch das Steuern des Ventils wird der Kolben der Zylinder-Kolbeneinheit 23 und wird über diesen Kolben der Träger 20 bewegt. Die Rückbewegung des Kolbens wird durch einen vom Steuermittel gesteuerten Abfluss des Druckmediums aus dem Zylinder und durch die vorgespannte Druck- oder Rückstellfeder bewirkt. Dadurch werden die Platten 20 im Uhrzeigersinn um die Trägerstange 22 geschenkt und der Träger 20 gelangt in eine dem Deckelsatz an der Reinigungsstelle C nahe Position. In anderen Ausführungsformen können andere Steuermittel, wie Nockenscheiben und dergl. zur Steuerung der Einheit 23 verwendet werden. Dabei umfassen bei den letztgenannten Einrichtungen diese sowohl das Steuermittel als auch das Antriebsmittel.The valve 25 of the unit 23 can be actuated by a control means known per se and therefore not shown. This can be based on an electrical circuit, for example. By controlling the valve, the piston of the cylinder-piston unit 23 is moved and the carrier 20 is moved via this piston. The return movement of the piston is brought about by an outflow of the pressure medium from the cylinder controlled by the control means and by the prestressed compression or return spring. As a result, the plates 20 are given clockwise around the support rod 22 and the support 20 comes into a position close to the set of covers at the cleaning point C. In other embodiments, other control means such as cam disks and the like can be used to control unit 23. In the case of the latter means both the control means and the drive means.

Im Beispiel der Fig. 1 wird bei der Reinigungsbewegung der Bürste 16 von der Position A weg und vor Erreichen der Position C, der Druck im Zylinder der Einheit 23 reduziert, wodurch der Träger 20 und damit die Bewegungsbahn der Bürste 16 in die an der Reinigungsstelle C dem Dekkelsatz nahe Position bewegt wird. Bei der Rückbewegung der Bürste 16 von der Position B zur Position A wird das Ventil 25, bevor die Bürste 16 die Position C erreicht, durch das Steuermittel geöffnet und damit der Abstand der Bewegungsbahn der Bürste 16 vom Deckelsatz an der Reinigungsstelle C vergrössert und damit die Bewegungsbahn in die vom Deckelsatz an der Reinigungsstelle entfernte Position gebracht.In the example of FIG. 1, during the cleaning movement of the brush 16 away from position A and before reaching position C, the pressure in the cylinder of the unit 23 is reduced, as a result of which the carrier 20 and thus the path of movement of the brush 16 into that at the cleaning point C is moved close to the cover set. When the brush 16 moves back from position B to position A, the valve 25, before the brush 16 reaches position C, is opened by the control means and thus the distance of the path of movement of the brush 16 from the cover set at the cleaning point C is increased and thus the Movement path brought into the position removed from the cover set at the cleaning point.

Auf diese Weise ergibt sich der Vorteil, dass bei der Reinigungsbewegung die Bürste 16 mit ihren Zähnen in greifender Position tief in die Garnitur 14 eintaucht und die Verunreinigungen gründlich entfernt und dass bei der Rückbewegung die Bürste 16 wenig oder überhaupt nicht in die Garnitur 14 eintaucht, sodass in dieser vorhandenes, zu entfernendes Material nicht gegen den Boden der Garnitur gestossen wird.In this way, there is the advantage that, during the cleaning movement, the brush 16 dips deeply into the clothing 14 with its teeth in the gripping position and thoroughly removes the impurities, and that during the return movement the brush 16 dips little or not at all into the clothing 14, so that existing material to be removed is not pushed against the bottom of the set.

Es ist ersichtlich, dass gemäss vorliegender Erfindung die Eintauchtiefe der Garnitur der Bürste 16 in die Garnitur 14 der Deckel 13 beliebig gewählt werden kann. Damit wird eine optimale Reinigung der Garnitur 14 und das Anpassen an verschiedene Verhältnisse ermöglicht.It can be seen that, according to the present invention, the immersion depth of the brush 16 set in the cover 14 set 13 can be chosen as desired. This enables optimal cleaning of the clothing 14 and adaptation to different conditions.

Nachdem die Bürste 16 ihre Rückbewegung aus der Position B begonnen hat, durchstreicht sie den Kamm 21, wobei der von ihr gehaltene Deckelputz 26 abfällt, sofern dieser nicht schon beim Durchstreichen anlässlich der von der Position A zur Position B erfolgten Reinigungsbewegung abgefallen ist. Der Deckelputz wird über einen Auffangbehälter 27 abgeführt. Im gezeigten Beispiel ist der Kamm 21 an den Platten 20 befestigt.After the brush 16 has started its return movement from the position B, it brushes through the comb 21, the cover plaster 26 held by it falling off, provided that this does not fall off when the brushing is carried out on the occasion of the cleaning movement from position A to position B. is. The cover plaster is removed via a collecting container 27. In the example shown, the comb 21 is attached to the plates 20.

Die Trägerstange 22 ist vorteilhafterweise nahe an einer Seitenkante der Platten 20 in der Weise angebracht, dass, wie in Fig. 1 und 2 gezeigt, die sich an der Reinigungsstelle C befindliche Bürstengarnitur und die Trägerstange 22, sich ungefähr gleich hoch über einer gedachten, durch die waagrechte Oberfläche des Deckelsatzes an der Deckelreinigungsstelle C definierten Ebene befinden. Damit ergibt sich die an sich erwünschte Bewegung des Trägers 20 an der Reinigungsstelle C in zum Deckelsatz praktisch senkrechter Richtung nach oben und unten.The support rod 22 is advantageously mounted close to a side edge of the plates 20 in such a way that, as shown in FIGS. 1 and 2, the brush set located at the cleaning point C and the support rod 22 are approximately the same height above an imaginary one the horizontal surface of the lid set is at the level defined at the lid cleaning point C. This results in the desired movement of the carrier 20 at the cleaning point C in the direction perpendicular to the set of covers up and down.

Im Ausführungsbeispiel der Fig. 2 sind wiederum Deckel 13 eines Deckelsatzes einer Wanderdeckelkarde gezeigt, von denen jeder Deckel 13 mit einer Garnitur 14 versehen ist. Die Bewegungsrichtung der Deckel 13 ist durch den Pfeil 15 angegeben. Eine Bürste 16 ist wiederum von einer Welle 17 getragen und um deren Achse 18 zwischen den Positionen A und B über die Position C, wie durch den Doppelpfeil 19 angegeben, hin und her schwenkbar. Die Welle 17 ist von zwei zu ihr senkrecht stehenden, einen Träger bildenden Platten 20 getragen. Ein Kamm 28 zur Reinigung der Bürste 16 ist in diesem Beispiel fest am nicht gezeichneten Kardengestell befestigt. Eine Trägerstange 22 und eine Zylinder-Kolbeneinheit 23, welche als Antriebsmittel dient, sind ebenfalls vorgesehen. die Einheit 23 dient wiederum zum Verschwenken der Platten bzw. des Trägers 20 zum Zweck, an der Reinigungsstelle C den Abstand der Bewegungsbahn der Bürste 16 von dem durch die Deckel 13 gebildeten Deckelsatz bzw. von deren Garnituren 14 zu variieren. Schliesslich ist noch ein Auffangbehälter 27 für den Deckelputz vorgesehen.In the embodiment of FIG. 2, again cover 13 of a cover set of a revolving flat card is shown, of which each cover 13 is provided with a clothing 14. The direction of movement of the cover 13 is indicated by the arrow 15. A brush 16 is in turn carried by a shaft 17 and can be pivoted about its axis 18 between positions A and B via position C, as indicated by the double arrow 19. The shaft 17 is supported by two plates 20 which are perpendicular to it and form a support. In this example, a comb 28 for cleaning the brush 16 is firmly attached to the card frame (not shown). A support rod 22 and a cylinder-piston unit 23, which serves as drive means, are also provided. the unit 23 in turn serves to pivot the plates or the carrier 20 for the purpose of varying the distance of the path of movement of the brush 16 from the set of covers formed by the covers 13 or from the sets 14 thereof at the cleaning point C. Finally, a collecting container 27 is also provided for the cover plaster.

Im Gegensatz zum Beispiel der Fig. 1 ist gemäss der Ausführungsform der Fig. 2 eine weitere Zylinder-Kolbeneinheit 29 als Antriebsmittel vorgesehen. Diese Einheit dient zum Verschieben der Platten 20 in zur Längserstreckung des Decksatzes an der Reinigungsstelle C parallelen Translationsbewegungen. Um solche Bewegungen zu ermöglichen, sind die Platten 20 mit Schlitzen 30 versehen. Die Platten 20 werden von der Trägerstange 22 und der Einheit 23 getragen. Die Deckelreinigungsstelle ist wiederum der Bereich der sich in der Position C befindlichen Bürste 16.In contrast to the example in FIG. 1, a further cylinder-piston unit 29 is provided as the drive means in accordance with the embodiment in FIG. 2. This unit is used to move the plates 20 in translational movements parallel to the longitudinal extension of the cover set at the cleaning point C. In order to enable such movements, the plates 20 are provided with slots 30. The plates 20 are carried by the support rod 22 and the unit 23. The lid cleaning point is again the area of the brush 16 located in position C.

Bei der Vorrichtung der Fig. 2 ist somit die Bürste 16 folgender Bewegungskomponenten fähig:
Schwenkbewegungen a, b, Bewegungen senkrecht zur Oberfläche des Deckelsatzes c, d, Bewegungen parallel zur Längserstreckung des Deckelsatzes e, f. Durch Kombinieren der einzelnen Bewegungskomponenten ergeben sich eine Vielzahl von Möglichkeiten, die Bewegungsbahn der Bürste 16 zu variieren, wobei auch die Geschwindigkeit des Bewegungslaufes miteinbezogen werden kann. Zur weiteren Erläuterung sei die Arbeitsweise des folgenden Ausführungsbeispieles eingehender betrachtet.2, the brush 16 is therefore capable of the following movement components:
Swiveling movements a, b, movements perpendicular to the surface of the cover set c, d, movements parallel to the longitudinal extent of the cover set e, f. By combining the individual movement components, there are a multitude of possibilities for varying the path of movement of the brush 16, the speed of the movement course also being able to be included. For a further explanation, the mode of operation of the following exemplary embodiment is considered in more detail.

Bei diesem Beispiel werden bei Beginn der Reinigungsbewegung a die Bewegungen gemäss den Komponenten a und c ausgeführt. Während des Durchgangs durch die Position C wird die Komponente f und unmittelbar daran anschliessend wird die Bewegung gemäss der Komponente d ausgeführt.In this example, the movements according to components a and c are carried out at the start of cleaning movement a. During the passage through position C, component f is carried out and immediately thereafter the movement according to component d is carried out.

Zur Erläuterung des Verlaufs der Bewegung der Bürste 16 bei dieser Arbeitsweise sei auf die Fig. 3 verwiesen. In dieser zeigt die dick ausgezogene Linie den Verlauf eines gegebenen Punktes der Bürste 16. Dies sei beispielsweise der Punkt 39 in Fig. 2. In der Fig. 2 ist noch die Garnitur 14 eingezeichnet. Die Position 31 bezeichnet die Lage der Achse 18 vor Beginn der Reinigungsbewegung a der Bürste 16, Position 32 die Lage der Achse 18 nach Ausführen der Bewegung c mittels der Einheit 23, Position 33 die Lage der Achse 18 nach Ausführen der Bewegung f mittels der Einheit 29 und Position 34 die Lage der Achse 18 nach Ausführen der beiden Bewegungen c und f. Wenn sich die Achse 18 an einer der Positionen 31, 32, 33, 34 befindet, so beschreibt der Punkt 39 der eine Schwenkung ausführenden Bürste 16 eine der gezeichneten Kreisbahnen, und zwar gehört zur Position 31 die Kreisbahn 35, zur Position 32 die Kreisbahn 36, zur Position 33 die Kreisbahn 36, zur Position 33 die Kreisbahn 37 und zur Position 34 die Kreisbahn 38.To explain the course of the movement of the brush 16 in this mode of operation, reference is made to FIG. 3. In this, the thick solid line shows the course of a given point of the brush 16. This is the point 39 in FIG. 2, for example. In FIG. 2, the clothing 14 is also shown. Position 31 denotes the location the axis 18 before the start of the cleaning movement a of the brush 16, position 32 the position of the axis 18 after performing the movement c by means of the unit 23, position 33 the position of the axis 18 after performing the movement f by means of the unit 29 and position 34 the position the axis 18 after executing the two movements c and f. If the axis 18 is located at one of the positions 31, 32, 33, 34, the point 39 of the brush 16 which executes a pivoting movement describes one of the circular paths shown, namely the circular path 35 at position 31 and the circular path 36 at position 32 , to position 33 the circular path 36, to position 33 the circular path 37 and to position 34 the circular path 38.

Falls nun nach dem Beginn der von der Position A ausgehenden, der Reinigung der Deckelgarnitur dienenden Reinigungsbewegung der Bürste 16 gemäss der Komponente a, die Bewegungen entsprechend der Komponente c und darauf die der Komponente f ausgeführt werden, so beschreibt der Punkt 39 eine der dick ausgezogenen Linie entsprechende Bahn. Diese verläuft anfänglich längs des Kreises 35 und endet im Kreis 38. In diesem Beispiel werden, nachdem die Bürste die Position C fast vollständig durchlaufen hat und die Bewegung f im wesentlichen beendet ist, die Platten 20 durch Ausführen der Bewegungskomponente d, wieder in ihre an der Reinigungsstelle C vom Deckelsatz entfernte Position gebracht. Dadurch wird die Bewegung des Punktes 39 auf den zur Position 33 gehörenden Kreis 37 gebracht. Der Ablauf dieses Vorgangs ist in Fig. 3 gezeigt. Nach Beendigung des letzteren und bevor die Bürste 16 wieder ihre Rückbewegung gemäss der Komponente b ausgeführt hat, muss irgendwann eine Bewegung gemäss der Komponente e ausgeführt werden. Dies bringt die am Ende ihrer Rückbewegung b in der Position A eintreffende Bürste wieder auf die Kreisbahn 35.If, after the start of the cleaning movement of the brush 16 according to component a, starting from position A and serving to clean the cover set, the movements corresponding to component c and then component f are carried out, point 39 describes one of the thickly drawn out lines Line corresponding train. This initially runs along the circle 35 and ends in the circle 38. In this example, after the brush has almost completely passed the position C and the movement f has essentially ended, the plates 20 are brought back into their position by executing the movement component d the cleaning point C removed from the lid set. As a result, the movement of point 39 is brought to circle 37 belonging to position 33. The course of this process is shown in FIG. 3. After the latter has ended and before the brush 16 has again carried out its return movement according to component b, a movement according to component e must be carried out at some point. This brings the brush arriving in position A at the end of its return movement b back onto the circular path 35.

Bei der soeben beschriebenen Arbeitsweise findet die Bewegung f statt, während sich die Bürste 16 über die Reinigungsstelle C bewegt. Die Bürste 16 taucht in dieser Arbeitsphase kräftig in die Garnitur ein, wobei die Eintauchtiefe durch die Wahl der Grösse der Bewegung c gegeben ist. Die Geschwindigkeit, mit der sich die Bürste 16 durch die Garnitur 14 bewegt, wird durch das Ueberlagern der Komponente f mit der Komponente a verlangsamt. Sie ist der um die Geschwindigkeit der Bewegung f verminderten, durch die Rotationsgeschwindigkeit der Bürste gegebenen Umfangsgeschwindigkeit gleich. Damit ergibt sich ein verbessertes Erfassen des wegzuschaffenden Materials. Zusätzlich erfolgt die Bewegung der Komponente d mit grosser Geschwindigkeit, was einem senkrecht nach oben erfolgenden Herausreissen gleichkommt. Die Kombination dieser Vorgänge trägt zu einer stark verbesserten Reinigung der Garnitur 14 bei.In the mode of operation just described, the movement f takes place while the brush 16 moves over the cleaning point C. The brush 16 plunges vigorously into the clothing during this working phase, the immersion depth being given by the choice of the size of the movement c. The speed at which the brush 16 moves through the clothing 14 is slowed down by superimposing component f with component a. It is equal to the peripheral speed reduced by the speed of the movement f and given by the rotational speed of the brush. This results in an improved detection of the material to be removed. In addition, component d moves at high speed, which is equivalent to tearing out vertically upwards. The combination of these processes contributes to greatly improved cleaning of the clothing 14.

Es zeigt sich somit, dass durch die verlangsamte Bewegung der in die Garnitur 14 eingetauchten Bürste 16 der pro Reinigungsbewegung a überstrichene Garniturstreifen etwas schmaler wird, und dass das Erfassen eines schmaleren Streifens der Garnitur 14 bei den einzelnen Eintauchbewegungen der Bürste 16 zusammen mit der langsameren Bewegung derselben relativ zum Decksatz bessere Resultate ergibt als ein rascherer Reinigungsvorgang über einen breiteren Streifen der Garnitur 14.It can thus be seen that the slower movement of the brush 16 immersed in the clothing 14 makes the clothing strip swept per cleaning movement a slightly narrower, and that the detection of a narrower strip of the clothing 14 during the individual immersion movements of the brush 16 together with the slower movement the same gives better results relative to the cover set than a faster cleaning process over a wider strip of clothing 14.

Auch in diesem Beispiel ist zum Reinigen der Bürste 16 ein periodisches Durchbewegen der letzteren durch den Kamm 28 vorgesehen. In diesem Beispiel ist jedoch, im Gegensatz zu dem der Fig. 1, der Kamm 28 nicht von den einen Träger bildenden Platten 20 getragen, sondern er ist fest am Kardengestell befestigt. Unter diesen Verhältnissen ist eine besonders vorteilhafte Ausführungsform dadurch gekennzeichnet, dass in der Arbeitsphase in der sich die Bürste im Bereich der Position B befindet, bei der Reinigungsbewegung a vor dem Durchgang der Bürste 16 durch den Kamm 28, die Platten 20 nochmals einer Bewegung c ausgesetzt sind, und damit, zusammen mit der Bewegungsbahn der Bürste 16, nochmals in ihre, dem Deckelsatz an der Reinigungsstelle nahe Lage versetzt werden. Man vermeidet auf diese Weise ein Eintauchen der Bürste in den Kamm 28 während der Reinigungsbewegung a, sodass bei dieser kein Deckelputz in die Bürste hineingerückt wird. Unmittelbar beim Beginn der Rückbewegung b der Bürste 16 und bevor diese wieder beim Kamm 28 angelangt ist, findet wieder eine Bewegung d statt, durch welche die Platten 20 wieder in ihre vom Deckelsatz entfernte Position versetzt werden. In dieser findet ein kräftiges Eintauchen der Zähne des Kamms 28 in die Garnitur der Bürste statt, wobei die Zähne des Kamms 28 sich in greifender Position befinden. Damit erhält man eine Verbesserung der Reinigung der Bürste 16, was wiederum eine Verbesserung der Reinigung der Garnitur 14 mit sich bringt.In this example, too, the brush 16 is periodically moved through the comb 28 to clean it. In this example, however, in contrast to that of FIG. 1, the comb 28 is not carried by the plates 20 forming a support, but is fixedly attached to the card frame. Under these conditions, a particularly advantageous embodiment is characterized in that in the working phase in which the brush is located in the area of position B, in the Cleaning movement a before the passage of the brush 16 through the comb 28, the plates 20 are again subjected to a movement c, and thus, together with the path of movement of the brush 16, are again placed in their position close to the cover at the cleaning point. This prevents the brush from dipping into the comb 28 during the cleaning movement a, so that no cover plaster is pushed into the brush during this. Immediately at the beginning of the return movement b of the brush 16 and before it has reached the comb 28 again, a movement d takes place, by means of which the plates 20 are moved back into their position removed from the cover set. The teeth of the comb 28 are immersed vigorously in the brush set, the teeth of the comb 28 being in the gripping position. This results in an improvement in the cleaning of the brush 16, which in turn leads to an improvement in the cleaning of the clothing 14.

Es ist ersichtlich, dass die Ausführungsform der Fig. 2 neben den gezeigten Beispielen noch viele, weitere Varianten zulässt. Je nach der Reihenfolge des Einsatzes der Bewegungskomponenten a, b, c, d, e und f und der Wahl der Geschwindigkeit des Ablaufens der Bewegungen sind Anpassungen an verschiedenste Verhältnisse möglich.It can be seen that the embodiment of FIG. 2 permits many other variants in addition to the examples shown. Depending on the order of use of the motion components a, b, c, d, e and f and the choice of the speed of the movements, adaptations to various conditions are possible.
