Description

Speiseeinrichtung für Karden, Krempel u.dgl. Feeding device for cards, cards and the like
Die Erfindung betrifft eine Speiseeinrichtung für Karden, Krempel u.dgl. mit einem vertikalen ersten Schacht, an dessen unterer Öffnung eine Speisewalze angeordnet ist, die mit einer unterhalb der Speisewalze angeordneten gegensinnig rotierenden Schlagwalze zu¬ sammenwirkt, und mit einem tangential von der Schlag¬ walze abgehenden zweiten Schacht.The invention relates to a feeding device for cards, cards and the like. with a vertical first shaft, at the lower opening of which a feed roller is arranged, which cooperates with an oppositely rotating impact roller arranged below the feed roller, and with a second shaft tangentially extending from the impact roller.
Bei Speiseeinrichtungen für Karden, Krempel und öffnungs- und Reinigungsmaschinen u.dgl. wird das Fasergut unter der Einwirkung von Schwerkraft und mit Luftdruckstützung aus einem als Reserveschacht be¬ zeichneten ersten Schacht einem Muldeneinzug zugeführt, in dem eine Speisewalze angeordnet ist (DE-PS 28 04 413) . Die Speisewalze drängt das flockige Fasermaterial in die eine Hälfte der Mulde, von wo es durch eine Öffnung im unteren Bereich der Mulde austritt. Unter- halb der Speisewalze befindet sich eine rotierende Schlagwalze, die an ihrer ümfangsflache Schlagleisten aufweist. Diese Schlagwalze, die in derselben Dreh¬ richtung rotiert wie die Speisewalze, schlägt nicht nur vom Umfang der Speisewalze Fasermaterial ab, sondern ihre Schlagleisten bewegen sich aus dem Bereich der Muldenöffnung auf die Spitze der öffnungskante zu. Das Fasermaterial, das sich im Bereich der Öffnungskante befindet, wird einer starken Umlenkung um diese Öffnungskante herum und somit einer starken Scher- und Zugbeanspruchung ausgesetzt. Durch diese hohe Schlag- belastung am öffnungsrand besteht die Gefahr, daß das Fasermaterial bricht und reißt. Diese Gefahr ist ins¬ besondere dann gegeben, wenn das Fasermaterial zu- sammenhängende Büschel bildet, die an der Umlenkstelle von den Schlagleisten gewissermaßen zerschlagen werden.For feeding devices for cards, cards and opening and cleaning machines and the like. the fiber material is fed under the action of gravity and with air pressure support from a first shaft, designated as a reserve shaft, to a trough feeder in which a feed roller is arranged (DE-PS 28 04 413). The feed roller pushes the flaky fiber material into one half of the trough, from where it exits through an opening in the lower region of the trough. Under- Half of the feed roller is a rotating impact roller, which has blow bars on its circumferential surface. This impact roller, which rotates in the same direction of rotation as the feed roller, not only cuts off fiber material from the periphery of the feed roller, but its blow bars move from the region of the trough opening to the tip of the opening edge. The fiber material, which is located in the area of the opening edge, is subjected to a strong deflection around this opening edge and thus to a strong shear and tensile stress. Due to this high impact load at the opening edge, there is a risk that the fiber material will break and tear. This danger arises in particular when the fiber material forms coherent tufts which are smashed to a certain extent by the blow bars at the deflection point.
Es ist ferner eine Speiseeinrichtung für Karden und Krempel u.dgl. bekannt (DE-OS 33 36 517) , bei der die Speisewalze gegensinnig zur Schlagwalze angetrieben wird.It is also a feeding device for cards and cards and the like. known (DE-OS 33 36 517), in which the feed roller is driven in opposite directions to the beater roller.
Bei den bekannten Speiseeinrichtungen kann im Bereich der Schlagwalze an der Schachtwand ein Rollen der auf- gelösten Faserflocken entstehen, das zu unerwünschten Agglomerationen führen kann.In the known feeding devices, a roll of the dissolved fiber flakes can occur in the area of the beater roller on the shaft wall, which can lead to undesired agglomerations.
Der Erfindung liegt die Aufgabe zugrunde, eine Speise¬ einrichtung der eingangs genannten Art zu schaffen, mit der ein Rollen des Faεermaterials entlang von Schacht¬ wänden verhindert ist und wobei eine geringere Be¬ anspruchung des Fasermaterials gewährleistet ist.The invention is based on the object of providing a feed device of the type mentioned at the outset, with which rolling of the fiber material along shaft walls is prevented and less stress on the fiber material is ensured.
Zur Lösung dieser Aufgabe dienen die Merkmale des Hauptanspruchs. Bei einer Neigung der Ebene durch die Drehachsen der Speise- und Schlagwalze, nämlich von mindestens 15° bis zu ca. 90° gegenüber der Vertikalebene durch den Walzenmittelpunkt der Schlagwalze, und zwar in Dreh- richtung der Schlagwalze geneigt, ist gewährleistet, daß das Flockenmaterial aus dem ersten Schacht nahezu geradlinig in den zweiten Schacht gelangt, wobei die Faserflocken im Bereich der Schlagstelle nicht auf Schachtwänden abrollen können und sich auf diese Weise zu neuen Flockenbüscheln zusammenballen können. Außer¬ dem wird erreicht, daß das Fasermaterial in hohem Maße schonend behandelt wird. Die Anordnung der Walzen er¬ möglicht eine kompakte Bauweise der Speiseeinrichtung.The features of the main claim serve to solve this problem. If the plane is inclined by the axes of rotation of the feed and beater roller, namely from at least 15 ° to approximately 90 ° with respect to the vertical plane through the center of the beater roller, and inclined in the direction of rotation of the beater roller, it is ensured that the flake material almost straight from the first shaft to the second shaft, whereby the fiber flakes cannot roll on shaft walls in the area of the impact point and can thus clump together into new tufts of flakes. In addition, it is achieved that the fiber material is treated in a highly gentle manner. The arrangement of the rollers enables a compact construction of the feed device.
Die Speisewalze ist im wesentlichen mittig in dem Schachtguerschnitt am Ende des ersten Schachtes ange¬ ordnet.The feed roller is arranged essentially centrally in the shaft cross section at the end of the first shaft.
Der zweite Schacht verläuft im wesentlichen in Ver- längerung des ersten Schachtes, wodurch das Flocken¬ material von dem ersten Schacht in den zweiten Schacht einen im wesentlichen geradlinigen Weg unter größt¬ möglicher Schonung des Fasermaterials ausführt.The second shaft essentially extends the first shaft, as a result of which the flake material runs from the first shaft into the second shaft in a substantially straight path while protecting the fiber material as much as possible.
Der Klemmpunkt zwischen der Speisewalze und der Schlag¬ walze ist dabei vorzugsweise innerhalb der Breite der Schächte angeordnet.The nip between the feed roller and the beater roller is preferably arranged within the width of the shafts.
Im folgenden wird unter Bezugnahme auf die einzige Figur ein Ausführungsbeispiel der Erfindung näher1 er¬ läutert.In the following, an embodiment of the invention is explained in more detail 1 with reference to the single figure.
In der Zeichnung ist ein schematischer Querschnitt durch eine Speiseeinrichtung dargestellt. Die Speisevorrichtung weist einen vertikalen ersten Schacht 1 auf, in welchem das Fasergut enthalten ist. In dem ersten Schacht 1 sinkt das Fasergut unter Schwer- krafteinfluß nach unten. Diese Abwärtsbewegung des Faserguteε wird zusätzlich durch Luftdruck unterstützt. Die Transportluft kann dabei an zumindest einer Schachtwand 2 in eine Abluftkammer 3 austreten.The drawing shows a schematic cross section through a feed device. The feed device has a vertical first shaft 1, in which the fiber material is contained. In the first shaft 1, the fiber material sinks under the influence of gravity. This downward movement of the fiber material is additionally supported by air pressure. The transport air can exit at least one shaft wall 2 into an exhaust air chamber 3.
Am unteren Ende des ersten Schachtes 1 ist in einer Öffnung 3 eine angetriebene Speisewalze 4 angeordnet, die bei dem Ausführungsbeispiel in Gegenuhrzeigersinn rotiert. Die Speisewalze 4 ist in etwa mittig unter dem ersten Schacht 1 angeordnet.At the lower end of the first shaft 1, a driven feed roller 4 is arranged in an opening 3, which rotates counterclockwise in the exemplary embodiment. The feed roller 4 is arranged approximately centrally under the first shaft 1.
Unterhalb der Öffnung und der Speisewalze 4 ist die ebenfalls angetriebene Schlagwalze 7 angeordnet, die im Uhrzeigersinn rotiert. Die Schlagwalze 7 kann auf ihrem Umfang verteilt angeordnete Schlagleisten aufweisen, die beispielsweise mehrere radial abstehende Nadeln tragen. Der Achsabstand von Speisewalze 4 und Schlag¬ walze 7 ist so gewählt, daß sich die beiden Walzen ge¬ rade nicht mehr berühren.Below the opening and the feed roller 4, the likewise driven beater roller 7 is arranged, which rotates clockwise. The beater roller 7 can have beater bars arranged distributed over its circumference, which for example carry a plurality of radially projecting needles. The center distance of the feed roller 4 and the beater roller 7 is selected so that the two rollers are no longer in contact.
Die Vertikalen durch die Schlag- bzw. Speisewalzen 4,7 sind versetzt zueinander, wobei die Verbindungsebene durch die Drehungsmittelpunkte der Walzen gegenüber der Vertikalen durch die Schlagwalze 7 um einen Winkel zwischen 15° und 90°, vorzugsweise 45°, in Drehrichtung der Schlagwalze geneigt ist. Dadurch ist der Klemmpunkt zwischen den beiden Walzen im wesentlichen innerhalb der Schachtbreite sowohl des oberen Schachtes 1 als auch des unteren Schachtes 8, der tangential von der Schlagwalze 7 im wesentlichen vertikal, oder gering¬ fügig um 10° von der Vertikalen durch den oberen Schachtquerschnitt abstehend, abgeht. Die Schlagwalze 7 übt eine schonende Klemmwirkung auf das Fasermaterial aus, das zu Flocken ausgezupft, jedoch nicht übermäßig mechanisch beansprucht wird und das im wesentlichen seine Bewegungsrichtung, nämlich vertikal von oben nach unten, beibehält. The verticals through the beater or feed rollers 4, 7 are offset from one another, the connecting plane being inclined in the direction of rotation of the beater roller by an angle between 15 ° and 90 °, preferably 45 °, relative to the vertical axis of the rollers relative to the vertical through the beater roller 7 is. As a result, the nip between the two rollers is essentially within the shaft width of both the upper shaft 1 and the lower shaft 8, which is tangentially from the beater roller 7 essentially vertical, or slightly at 10 ° from the vertical through the upper one Shaft cross section protruding, coming off. The beater roller 7 exerts a gentle clamping action on the fiber material, which is plucked into flakes, but not excessively mechanically stressed, and which essentially maintains its direction of movement, namely vertically from top to bottom.
