Definitions
- the present invention relates to a card with a device for adjusting the carding gap between revolving carding elements and a drum, the carding elements interacting with at least one arcuate slide bar which are arranged on both sides of the drum on a side plate, each slide bar having at least one wedge-shaped bar, which is slidably arranged on a mutually aligned wedge-shaped support element, the bar being adjustable and fixable on the support element by means of a device.
- flat bars with flexible card clothing (revolving flat) and / or fixed carding elements with all-steel clothing are used as carding elements for the carding process.
- the flat bars have pins on their end faces, which on the one hand interact with drive belts to circulate the flat bars, on the other hand slide on a slide bar which is arranged on both sides of the carding drum and via which the carding gap can be adjusted.
- the sliding strips can be adjusted using radial adjusting devices so that the carding gap can be enlarged or reduced.
- actuators or mechanical devices are used with which the radius of the sliding strips can be increased or decreased.
- An alternative or addition to this is a wedge-shaped adjustment of the sliding strips in the circumferential direction of the card drum, which means A small and precise change in the radius of the sliding strip is effected over a large travel range.
- This device can also be operated mechanically or by a motor. A rough adjustment of the slide bar takes place via a plurality of radially arranged adjusting spindles, the exact adjustment however via the wedge-shaped adjustment device effective in the circumferential direction of the carding drum.
- the DE 19831139 B4 and CH 692348 A5 describe a sliding strip whose radius can be adjusted using a sliding wedge system.
- a pocket in which a gear drive is arranged is incorporated within the sliding strip.
- This gear drive takes up a relatively large installation space, which weakens the strength of the sliding strip and thus causes an additional deviation from the exact pitch circle shape.
- the upper slide bar is moved around the circumference of the lower slide bar by means of traction means.
- the WO 2007/038891 A1 also discloses the adjustment of the carding gap by adjusting the sliding guide. This will be point by point bent by means of adjusting elements, so that a non-uniform bending radius is created.
- the object of the invention is to develop an adjusting device on the slide strip of a card, with which an exact adjustability is possible and which improves the existing system.
- the card has an adjusting device for adjusting the carding gap between revolving carding elements and a drum, the carding elements interacting with at least one arcuate slide bar, which are arranged on both sides of the drum on a side plate, each slide bar having at least one wedge-shaped bar that is displaceable is arranged on a mutually aligned wedge-shaped support element, the bar being adjustable and fixable on the support element by means of a device.
- the invention includes the technical teaching that by fixing the device to a lateral end face of the support element, the slide bar can be designed with a higher moment of resistance and therefore the slide surface on which the carding elements run comes closer to the ideal arcuate contour.
- essential functional elements are relocated to the outside of the sliding strip so that its cross section is not excessively weakened.
- the device preferably has two guides arranged in a cross shape with respect to one another, one guide being designed as an arcuate elongated hole in which a guide element is slidably arranged.
- the setting and fixing device can be moved to an outside of the sliding strip via the guides, which are arranged cross-shaped to one another.
- a guide is arranged as an arcuate slot in the side wall of the support element.
- Fig. 1 shows a card according to the prior art, in which fiber flocks are guided via a chute to a feed roller 1, a feed table 2, via several lickerins 3a, 3b, 3c, to the drum 4 or the tambour.
- the fibers of the fiber flocks are parallelized and cleaned by means of stationary rotating carding elements 14 arranged on a revolving flap system 17.
- the resulting fiber web is then conveyed via a doffer 5, a doffing roller 6 and several nip rollers 7, 8 to a web guide element 9, which feeds the fiber web with a funnel 10 formed into a sliver, which is transferred via take-off rollers 11, 12 to a subsequent processing machine or a can 15.
- the adjustment of the carding elements 14 to the drum 4 takes place via slide strips 18, which have elements aligned with one another in a wedge shape.
- Figure 2 shows schematically the mode of operation of the slide strips 18, which are fastened on each side of the card to the side of the machine frame (not shown) on an approximately semicircular rigid side plate.
- the sliding strips 18 each comprise at least one support element 19 and one strip 20, which are arranged on both sides in the area of the side shields.
- the support element 19 is arcuate and can be rigidly cast on the side plate. Alternatively, the support element 19 can also be arranged adjustably on the side plate and can be adjusted radially by means of a plurality of adjusting means 22, the support element 19 being slightly bent in the process.
- the support element 19 has a convex outer surface 19a and an underside 19b. Above the support element 19 there is arranged an arcuately displaceable bar 20, which can for example consist of a slidable plastic.
- the carding elements 14, not shown here, slide on the bar 20 with their pins protruding from the lateral end faces on the outer surface 20a.
- the radius r1 is assigned to the outer surface. If the radius r1 increases, the carding gap increases, since the flat bars are guided at a greater distance from the drum 4.
- the bar 20 has a convex outer surface 20a and a concave inner surface 20b.
- the concave inner surface 20b rests on the convex surface 19a, both the support element 19 and the bar 20 being wedge-shaped and aligned with respect to one another in their inclination.
- the bar 20 can be guided laterally through the support element 19, for example through raised webs, so that the bar 20 is arranged in a groove in the support element 19 ( Figure 3 ).
- a displacement of the two elements 19, 20 with respect to one another causes a change in the outer diameter or the radius r1, so that the distance (carding gap) between carding element 14 and the drum 4 is changed.
- the wedge system shown here has the advantage that a small change in the radius r1 is brought about by a large adjustment path arranged in the radial circumferential direction.
- the two elements 19, 20 can be displaced relative to one another by manual adjustment or a motorized actuator, as described below.
- the support element 19 has an arcuate guide in the area of a lateral end face, which guide can be designed as an elongated hole 19c, the guide extending over an arc of approximately 20 ° on the circumference of the support element 19.
- the depth of the elongated hole 19c extends only up to approximately the middle of the cross section of the support element 19.
- a guide element 21 is slidably arranged within the elongated hole 19c and can be clamped by a pin 25 with a fastening element 23.
- the guide element 21 can be designed as a slot nut, for example.
- the guide element 21 can also be slightly bent in accordance with the arcuate elongated hole 19c in order to prevent jamming.
- a further elongated hole 19d is arranged orthogonally to the elongated hole 19c within the support element 19 and extends from the outer surface 19a to the elongated hole 19c. Due to the cross-shaped arrangement of the elongated holes 19c, 19d, which meet in the central cross section of the support element 19 and end there, the moment of resistance of the support element 19 is only insignificantly reduced. Adjusting and thus bending the support element 19 by the adjusting means 22 causes almost no deviation of the outer surface 19a from the ideal arch shape due to the only insignificantly weakened cross section.
- the elongated hole 19d extends over the same arc or circumference as the elongated hole 19c and receives a driver 24 which is fastened in the guide element 21 and is guided in the elongated hole 19d.
- the driver 24 protrudes with its head over the outer surface 19a.
- the head 24a of the driver 24 in turn engages in a receptacle or hole in the strip 20 without play.
- the head 24a of the driver 24 can be a spherical cap or spherical head be trained.
- two catches 24 can also be connected to and arranged with the guide element 21 at a distance from one another within the elongated hole 19d.
- the bar 20 By loosening the fastening element 23 and shifting the guide element 21 within the elongated hole 19c, the bar 20 can thus be shifted on the support element 19. This changes the radius r1, so that the size of the carding gap is changed.
- the carding gap can be changed by 0.025 mm by means of an arcuate displacement of the strip 20 over the support element 19 of, for example, 10 mm.
- the invention has the advantage that the cross section of the support element 19 is weakened to a lesser extent and thus the outer contour of the outer surface 20a deviates less strongly from the ideal arc shape. The carding gap at this point can thus be set more precisely.
- a safeguard against adjustment can take place by means of a form-fitting connection of the fastening element 23 to the support element 19.
- a display scale 26 is arranged on the side of the support element 19 below the elongated hole 19c and interacts with a marking or an arrow on the fastening element 23.
- the guide element 21 can also be motorized, for example via an in Figure 4 spindle drive shown can be adjusted.
- the guide element 21 can be connected by means of a pin 25 or a fastening element to a spindle nut 31 which interacts with one end of a spindle 30.
- the spindle nut 31 is rotatably connected to the pin 25 or the fastening element.
- the other end of the spindle 30 is rotatably arranged in a bearing 32.
- This bearing 32 is also rotatably arranged at a fixed point, for example on the support element 19.
- the rotatable connection between the spindle nut 31 and pin 25 and the rotatable arrangement of the bearing 32 ensure that when the spindle 30 changes position when it is actuated does not bend.
- the rotatable actuation of the spindle 30 can take place via an electromotive drive 33, or via a point of application for a manually operated tool, for example a ratchet with a hexagon socket.
- a safeguarding or fixability of the device against possible adjustment takes place through the self-locking of the spindle 30 and / or through an additional form-fitting securing, for example according to the embodiment of FIG Figure 3 .

Description
Die vorliegende Erfindung betrifft eine Karde mit einer Vorrichtung zur Einstellung des Kardierspaltes zwischen umlaufenden Kardierelementen und einer Trommel, wobei die Kardierelemente mit mindestens einer bogenförmigen Gleitleiste zusammenwirken, die beidseitig der Trommel an einem Seitenschild angeordnet sind, wobei jede Gleitleiste zumindest eine keilförmig ausgebildete Leiste aufweist, die verschiebbar auf einem gegeneinander ausgerichteten keilförmigen Auflageelement angeordnet ist, wobei die Leiste auf dem Auflageelement mittels einer Vorrichtung einstellbar und fixierbar ist.The present invention relates to a card with a device for adjusting the carding gap between revolving carding elements and a drum, the carding elements interacting with at least one arcuate slide bar which are arranged on both sides of the drum on a side plate, each slide bar having at least one wedge-shaped bar, which is slidably arranged on a mutually aligned wedge-shaped support element, the bar being adjustable and fixable on the support element by means of a device.
An Karden aktueller Bauform werden für den Kardierprozess als Kardierelemente Deckelstäbe mit flexiblen Garnituren (Wanderdeckel) und/oder Festkardierelemente mit Ganzstahlgarnituren benutzt. Die Deckelstäbe weisen an ihren Stirnseiten Stifte auf, die einerseits mit Antriebsriemen zum Umlaufen der Deckelstäbe zusammenwirken, andererseits auf einer Gleitleiste gleiten, die beidseitig der Kardentrommel angeordnet ist und über die der Kardierspalt eingestellt werden kann. Die Gleitleisten können über radiale Stellvorrichtungen so eingestellt werden, dass der Kardierspalt vergrößert oder verkleinert werden kann. Hierzu werden Stellantriebe oder mechanische Vorrichtungen verwendet, mit denen der Radius der Gleitleisten vergrößert oder verkleinert werden kann. Eine Alternative oder Ergänzung hierzu ist eine keilförmige Anstellung der Gleitleisten in Umfangsrichtung der Kardentrommel, womit über einen großen Stellweg eine kleine und genaue Radiusänderung der Gleitleiste bewirkt wird. Auch diese Vorrichtung kann mechanisch oder motorisch betrieben werden. Eine grobe Einstellung der Gleitleiste erfolgt dabei über mehrere radial angeordnete Stellspindeln, die genaue Einstellung jedoch über die in Umfangsrichtung der Kardentrommel wirksame keilförmige Einstellvorrichtung.On cards of the current design, flat bars with flexible card clothing (revolving flat) and / or fixed carding elements with all-steel clothing are used as carding elements for the carding process. The flat bars have pins on their end faces, which on the one hand interact with drive belts to circulate the flat bars, on the other hand slide on a slide bar which is arranged on both sides of the carding drum and via which the carding gap can be adjusted. The sliding strips can be adjusted using radial adjusting devices so that the carding gap can be enlarged or reduced. For this purpose, actuators or mechanical devices are used with which the radius of the sliding strips can be increased or decreased. An alternative or addition to this is a wedge-shaped adjustment of the sliding strips in the circumferential direction of the card drum, which means A small and precise change in the radius of the sliding strip is effected over a large travel range. This device can also be operated mechanically or by a motor. A rough adjustment of the slide bar takes place via a plurality of radially arranged adjusting spindles, the exact adjustment however via the wedge-shaped adjustment device effective in the circumferential direction of the carding drum.
Da nach heutigem Stand die Einstellung des Kardierspaltes und damit die Anpassung der Gleitleiste fast nur bei einem Maschinenstillstand nach einem Garniturenwechsel erfolgt, kann für die Mehrzahl der Anwendungen eine mechanische und manuelle Einstellung der Gleitleiste über das Keilsystem ausreichend sein.Since the setting of the carding gap and thus the adjustment of the sliding bar almost only takes place when the machine is at a standstill after a clothing change, mechanical and manual adjustment of the sliding bar via the wedge system can be sufficient for the majority of applications.
Da heute die Karde mit einem sehr engen Kardierspalt von 1/100 bis 5/100 mm betrieben wird, wird von der Oberfläche der Gleitleiste, auf der die Stifte der Deckelstäbe gleiten, eine exakt gerundete Kontur erwartet. Dies stimmt aber mit der Realität nicht überein, da im Bereich der Angriffspunkte der Stellspindel die Oberfläche der Gleitleisten Ausbuchtungen aufweisen, die von der exakten Rundung abweichen. Damit ergibt sich an diesen Stellen ein größerer Kardierabstand, oder je nach Einstellung zwischen den Angriffspunkten der Stellspindel ein kleinerer Kardierabstand.Since today the card is operated with a very narrow carding gap of 1/100 to 5/100 mm, an exactly rounded contour is expected from the surface of the sliding strip on which the pins of the flat bars slide. However, this does not agree with reality, since in the area of the points of application of the adjusting spindle the surface of the sliding strips have bulges that deviate from the exact rounding. This results in a larger carding distance at these points or, depending on the setting between the points of application of the adjusting spindle, a smaller carding distance.

Aufgabe der Erfindung ist die Weiterbildung einer Einstellvorrichtung an der Gleitleiste einer Karde, mit der eine exakte Einstellbarkeit möglich ist und die das bestehende System verbessert.The object of the invention is to develop an adjusting device on the slide strip of a card, with which an exact adjustability is possible and which improves the existing system.
Die Aufgabe wird gemäß dem Oberbegriff des Anspruches 1 mit den jeweils kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object is achieved according to the preamble of claim 1 with the respective characterizing features. Advantageous further developments of the invention are given in the dependent claims.
Erfindungsgemäß weist die Karde eine Einstellvorrichtung zur Einstellung des Kardierspaltes zwischen umlaufenden Kardierelementen und einer Trommel auf, wobei die Kardierelemente mit mindestens einer bogenförmigen Gleitleiste zusammenwirken, die beidseitig der Trommel an einem Seitenschild angeordnet sind, wobei jede Gleitleiste zumindest eine keilförmig ausgebildete Leiste aufweist, die verschiebbar auf einem gegeneinander ausgerichteten keilförmigen Auflageelement angeordnet ist, wobei die Leiste auf dem Auflageelement mittels einer Vorrichtung einstellbar und fixierbar ist.According to the invention, the card has an adjusting device for adjusting the carding gap between revolving carding elements and a drum, the carding elements interacting with at least one arcuate slide bar, which are arranged on both sides of the drum on a side plate, each slide bar having at least one wedge-shaped bar that is displaceable is arranged on a mutually aligned wedge-shaped support element, the bar being adjustable and fixable on the support element by means of a device.
Die Erfindung schließt die technische Lehre ein, dass durch eine Fixierung der Vorrichtung an einer seitlichen Stirnseite des Auflageelementes die Gleitleiste mit einem höheren Widerstandsmoment ausgebildet werden kann und daher die Gleitfläche, auf der die Kardierelemente laufen, der idealen bogenförmigen Kontur näherkommt. Im Unterschied zum Stand der Technik werden wesentliche Funktionselemente auf die Außenseite der Gleitleiste verlegt, so dass deren Querschnitt nicht übermäßig geschwächt wird.The invention includes the technical teaching that by fixing the device to a lateral end face of the support element, the slide bar can be designed with a higher moment of resistance and therefore the slide surface on which the carding elements run comes closer to the ideal arcuate contour. In contrast to the prior art, essential functional elements are relocated to the outside of the sliding strip so that its cross section is not excessively weakened.
Vorzugsweise weist die Vorrichtung zwei kreuzförmig zueinander angeordnete Führungen auf, wobei eine Führung als bogenförmiges Langloch ausgebildet ist, in der ein Führungselement verschiebbar angeordnet ist. Über die kreuzförmig zueinander angeordneten Führungen kann die Einstell- und Fixiervorrichtung auf eine Außenseite der Gleitleiste verlegt werden. Dabei ist eine Führung als bogenförmiges Langloch in der Seitenwand des Auflageelementes angeordnet.The device preferably has two guides arranged in a cross shape with respect to one another, one guide being designed as an arcuate elongated hole in which a guide element is slidably arranged. The setting and fixing device can be moved to an outside of the sliding strip via the guides, which are arranged cross-shaped to one another. A guide is arranged as an arcuate slot in the side wall of the support element.

Die Gleitleisten 18 umfassen zumindest jeweils ein Auflageelement 19 und eine Leiste 20, die beidseitig im Bereich der Seitenschilde angeordnet sind. Dabei ist das Auflageelement 19 bogenförmig ausgebildet und kann starr am Seitenschild angegossen sein. Alternativ kann das Auflageelement 19 auch einstellbar am Seitenschild angeordnet sein und mittels mehrerer Stellmittel 22 radial verstellt werden, wobei das Auflageelement 19 dabei leicht gebogen wird. Das Auflageelement 19 weist eine konvexe Außenfläche 19a und eine Unterseite 19b auf. Oberhalb des Auflageelementes 19 ist eine bogenförmig verschiebbare Leiste 20 angeordnet, die beispielsweise aus einem gleitfähigen Kunststoff bestehen kann. Auf der Leiste 20 gleiten die hier nicht dargestellten Kardierelementen 14 mit ihren an den seitlichen Stirnflächen herausragenden Stiften auf der Außenfläche 20a. Der Außenfläche ist der Radius r1 zugeordnet. Vergrößert sich der Radius r1, vergrößert sich der Kardierspalt, da die Deckelstäbe in einem größeren Abstand von der Trommel 4 geführt werden. Die Leiste 20 weist eine konvexe Außenfläche 20a und eine konkave Innenfläche 20b auf. Die konkave Innenfläche 20b liegt auf der konvexen Fläche 19a auf, wobei sowohl das Auflageelement 19 wie auch die Leiste 20 keilförmig ausgebildet und in der Neigung gegeneinander ausgerichtet sind. Die Leiste 20 kann dabei seitlich durch das Auflageelement 19 geführt werden, beispielsweise durch hoch gezogene Stege, so dass die Leiste 20 in einer Nut des Auflageelementes 19 angeordnet ist (
Nach
Über ein Lösen des Befestigungselementes 23 und Verschieben des Führungselementes 21 innerhalb des Langloches19c kann damit die Leiste 20 auf dem Auflageelement 19 verschoben werden. Damit ändert sich der Radius r1, so dass der Kardierspalt in der Größe verändert wird. So kann über eine bogenförmige Verschiebung der Leiste 20 über dem Auflageelement 19 von beispielsweise 10 mm der Kardierspalt um 0,025 mm verändert werden. Die Erfindung hat im Gegensatz zum Stand der Technik den Vorteil, dass der Querschnitt des Auflageelementes 19 weniger stark geschwächt wird und damit die Außenkontur der Außenfläche 20a weniger stark von der idealen Bogenform abweicht. Der Kardierspalt an dieser Stelle ist damit genauer einstellbar. Eine Absicherung gegen Verstellen kann durch eine formschlüssige Anbindung des Befestigungselementes 23 an dem Auflageelement 19 erfolgen. Seitlich am Auflageelement 19 unterhalb des Langloches19c ist eine Anzeigeskala 26 angeordnet, die mit einer Markierung oder einem Pfeil am Befestigungselement 23 zusammenwirkt.By loosening the
