Description

Verfahren und Vorrichtung zum Dosieren von^Ea-OduktenMethod and device for dosing ^ Ea adducts
Die Erfindung betrifft ein Verfahren zum Dosieren von Produkten, die in einer vordefinierten Menge einer Verpackung zugeführt werden und bei dem eine Dosiermenge durch ein Öffnen und Schließen mindestens eines Ventils festgelegt wird.The invention relates to a method for dosing products, which are supplied in a predefined amount of packaging and in which a dosage is set by opening and closing at least one valve.
Die Erfindung betrifft darüber hinaus eine Vorrichtung zum Dosieren von Produkten, die in einer vordefinierten Menge einer Verpackung zugeführt werden, wobei die Vorrichtung mindestens ein Ventil aufweist, das einen Produktstrom durch Öffnen und Schließen eines Förderweges steuert oder regelt und das ein Ventilgehäuse aufweist, in dem mindestens ein Sperrelement positionierbar im Förderweg angeordnet ist.The invention further relates to a device for dosing products, which are supplied in a predefined amount of packaging, wherein the device comprises at least one valve which controls or regulates a product flow by opening and closing a conveying path and which has a valve housing in which at least one blocking element is arranged positionable in the conveying path.
Derartige Vorrichtungen und Verfahren dienen beispielsweise zur Abfüllung und/oder Mengendosierung von schüttfähigen, fließfähigen oder pastösen Produkten oder Produkten mit stückigen Anteilen insbesondere auch von Nahrungsmittelprodukten, beispielsweise von Getränken, anderen flüssigen oder pastösen Nahrungsmitteln, von stückigen Lebensmitteln und/oder von Gemischen oder Gemengen der oben aufgeführten Lebensmittel oder Produkte. Zur Abfüllung derartiger Produkte muß in der Regel ein großer Öffnungsquerschnitt bereitgestellt und bei einem Schließen des Ven- tils muß das Produkt möglichst abgeschnitten werden. Derartige Anforderungen liegen insbesondere auch im Bereich der aseptischen Abfüllung von Nahrungsmitteln vor. Für derartige aseptische Anwendungen werden häufig sogenannte Pinauslaufe eingesetzt. Im nicht aseptischen Bereich ist es bekannt, Walzenausläufe oder ähnliche Einrichtungen zu verwenden.Such devices and methods are used, for example, for filling and / or quantity dosage of pourable, flowable or pasty products or products with particulate portions especially of food products, such as beverages, other liquid or pasty foods, lumpy foods and / or mixtures or mixtures of above listed foods or products. For the filling of such products, a large opening cross-section usually has to be provided and, upon closure of the valve, tils the product must be cut as possible. Such requirements are also present in particular in the field of aseptic filling of foodstuffs. For such aseptic applications so-called pin spouts are often used. In the non-aseptic field, it is known to use roller outlets or similar devices.
Die bislang bekannt gewordenen Verfahren und Vorrichtungen können noch nicht alle Anforderungen erfüllen, die an eine schnelle, zuverlässige und zugleich störungsarme Abfüllung gestellt werden.The hitherto known methods and devices can not meet all the requirements that are placed on a fast, reliable and at the same time trouble-free filling.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren der einleitend genannten Art derart zu verbessern, daß ein schneller und zuverlässiger Füllvorgang bei schonender Handhabung des abzufüllenden Produktes realisiert wird.Object of the present invention is therefore to improve a method of the aforementioned type such that a faster and more reliable filling process with gentle handling of the product to be filled is realized.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß durch eine steuerbare oder regelbare Positionierung von mindestens einem in einem Ventilgehäuse des Ventils angeordneten zylinderartigen Sperrelement mindestens eine im Bereich von Seitenflächen des Sperrelementes angeordnete Ausnehmung zur Bereitstellung einer Öffnungs- oder Schließposition und zum Festlegen eines Querschnittes einer Ausströmöffnung angeordnet wird.This object is achieved in that arranged by a controllable or controllable positioning of at least one arranged in a valve housing of the valve cylinder-like locking element at least one arranged in the region of side surfaces of the locking element recess for providing an opening or closing position and for defining a cross section of an outflow becomes.
Weitere Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der einleitend genannten Art derart zu konstruieren, daß eine schnelle und schonende Abfüllung des Produktes bei einfachem mechanischen Aufbau der Dosiereinrichtung unterstützt wird.Another object of the present invention is to construct a device of the aforementioned type such that a quick and gentle filling of the product is supported with a simple mechanical structure of the metering device.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sowohl ein erstes als auch ein zweites Sperrelement eine zylinderartige Ausbildung aufweist und im Bereich von Seitenflächen jeweils mit mindestens einer Ausnehmung versehen sind und daß die Sperrelemente relativ zueinander im wesentlichen koaxial angeordnet sind. Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung ermöglichen es, die Größe der resultierenden Austrittsöffnung variabel an das abzufüllende Produkt anzupassen und die Position der Austrittsöffnung in geeigneter Art und Weise zu verändern. Zur Vermeidung von Anhaftungen am Füllauslauf ist es möglich, daß der Auslauf in einer geschlossenen Position so verfahren wird, daß gegebenenfalls ein überhängendes Produkt beispielsweise an der Gehäusewand in eine bereitstehende Verpackung abgestreift werden kann. Es werden darüber hinaus Überschneidungen der Schließkanten bereitgestellt, die zu einem sauberen Trennen und/oder Durchschneiden des Produktes führen und hierdurch das Auftreten von Quetschungen vermeiden, die insbesondere bei der Abfüllung von Nahrungsmitteln unerwünscht sind. Es werden darüber hinaus mechanische Anschläge vermieden, so daß ein entsprechender Verschleiß lediglich gering ist.This object is achieved in that both a first and a second locking element has a cylinder-like design and are provided in the region of side surfaces each having at least one recess and that the locking elements are arranged relative to each other substantially coaxially. The inventive method and the device according to the invention make it possible to variably adapt the size of the resulting outlet opening to the product to be filled and to change the position of the outlet opening in a suitable manner. To avoid buildup on the filling spout, it is possible that the spout is moved in a closed position so that optionally an overhanging product can be stripped, for example, on the housing wall in a ready-made packaging. In addition, overlaps of the closing edges are provided, which result in a clean separation and / or cutting of the product and thereby avoid the occurrence of bruising, which are undesirable in particular in the filling of food. It also mechanical stops are avoided, so that a corresponding wear is low.
Durch den erfindungsgemäßen Auslauf wird im Vergleich zu einem Absperrventil die Erzeugung eines Druckes bei einem Öffnen der Ventileinrichtung innerhalb der Füllkammer vermieden. Darüber hinaus kommt der Auslauf außenseitig nicht direkt mit dem Produkt in Berührung, so daß eine Produktanhaftung am Auslauf minimiert ist. Schließlich ist auch die benötigte Kraft zum öffnen und Schließen der Dosiereinrichtung unabhängig vom Druck innerhalb der Füllkammer, so daß ein vergleichsweise gering dimensionierter Antrieb für die Sperrelemente ausreichend ist.As a result of the outlet according to the invention, the generation of a pressure when the valve device is opened within the filling chamber is avoided in comparison with a shut-off valve. In addition, the outlet on the outside does not come into direct contact with the product, so that product adhesion to the outlet is minimized. Finally, the force required to open and close the metering device is independent of the pressure within the filling chamber, so that a comparatively small dimensioned drive for the blocking elements is sufficient.
Eine kompakte Konstruktion wird dadurch unterstützt, daß die Sperrelemente relativ zueinander koaxial positioniert werden.A compact construction is assisted by coaxially positioning the locking elements relative to one another.
Eine einfache Ansteuerbarkeit kann dadurch erreicht werden, daß die Sperrelemente relativ zueinander durch eine Drehbewegung positioniert werden.A simple controllability can be achieved in that the locking elements are positioned relative to each other by a rotational movement.
Montage- und Demontagevorgänge werden dadurch erleichtert, daß die Sperrelemente relativ zueinander in einer axialen Richtung verschieblich angeordnet werden. Besonders vorteilhafte Dosiermöglichkeiten werden dadurch bereitgestellt, daß beide Sperrelemente in einem Ventilgehäuse beweglich gelagert werden.Assembly and disassembly operations are facilitated by the locking elements are slidably disposed relative to each other in an axial direction. Particularly advantageous metering options are provided by the fact that both locking elements are movably mounted in a valve housing.
Zur Anpassung an spezielle Dosieraufgaben wird vorgeschlagen, daß durch eine Anordnung der Sperrelemente relativ zueinander und relativ zum Ventilgehäuse eine Größe der Austrittsöffnung vorgegeben wird.To adapt to special metering tasks, it is proposed that a size of the outlet opening is predetermined by an arrangement of the locking elements relative to each other and relative to the valve housing.
Zur Vorgabe einer Dosiermenge erweist es sich als vorteilhaft, daß durch eine Anordnung der Sperrelemente relativ zueinander und relativ zum Ventilgehäuse eine Positionierung der Austrittsöffnung vorgegeben wird.To specify a metered amount, it proves to be advantageous that a positioning of the outlet opening is predetermined by an arrangement of the locking elements relative to each other and relative to the valve housing.
Insbesondere ist auch daran gedacht, daß durch eine Anordnung der Sperrelemente relativ zueinander und relativ zum Ventilgehäuse sowohl eine Größe als auch eine Positionierung der Austrittsöffnung vorgegeben wird.In particular, it is also contemplated that both a size and a positioning of the outlet opening is predetermined by an arrangement of the locking elements relative to each other and relative to the valve housing.
In den Zeichnungen sind Ausführungsbeispiele der Erfindung sche- matisch dargestellt. Es zeigen:Exemplary embodiments of the invention are shown schematically in the drawings. Show it:
Fig. 1 einen Querschnitt durch ein Ventil mit zwei relativ zueinander im wesentlichen koaxial angeordneten hülsenartigen Sperrelementen in einem geschlossenen Zustand des Ventils,1 shows a cross section through a valve with two sleeve-like locking elements arranged substantially coaxially relative to one another in a closed state of the valve,
Fig. 2 die Anordnung gemäß Fig. 1 in einem geöffneten Zustand des Ventils undFig. 2 shows the arrangement of FIG. 1 in an open state of the valve and
Fig. 3 eine perspektivische Darstellung der beiden hülsenartigen Sperrelemente in einem auseinandergenommenen Zustand.Fig. 3 is a perspective view of the two sleeve-like locking elements in a disassembled state.
Gemäß der Ausführungsform in Fig. 1 ist die Vorrichtung zum Dosieren von Produkten mit einem Ventil (1) versehen, das im Bereich eines Förderweges (2) angeordnet ist. Innerhalb eines Ven- tilgehäuses (3) sind ein erstes Sperrelement (4) und ein zweites Sperrelement (5) angeordnet. Relativ zu einer Querachse (6) erstrecken sich die Sperrelemente (4, 5) im wesentlichen relativ zueinander koaxial und hülsenartig.According to the embodiment in Fig. 1, the device for dosing products with a valve (1) is provided, which is arranged in the region of a conveying path (2). Within a Venous Tilgehäuses (3) a first blocking element (4) and a second blocking element (5) are arranged. Relative to a transverse axis (6) extend the locking elements (4, 5) substantially relative to each other coaxially and sleeve-like.
Die Anordnung der Bauelemente erfolgt hierbei derart, daß das Ventilgehäuse (3) außenseitig positioniert ist und das erste Sperrelement (4) führt. Innerhalb des ersten Sperrelementes (4) ist das zweite Sperrelement (5) angeordnet. Die Anordnung erfolgt hierbei insbesondere derart, daß das erste Sperrelement (4) relativ zum Ventilgehäuse (3) beweglich angeordnet ist und daß das zweite Sperrelement (5) innerhalb des ersten Sperrelementes (4) beweglich angeordnet ist. Die Beweglichkeit ist hierbei als eine Verdrehbarkeit der Bauelemente relativ zueinander und um die Querachse (6) herum realisiert.The arrangement of the components takes place in such a way that the valve housing (3) is positioned on the outside and the first blocking element (4) leads. Within the first blocking element (4), the second blocking element (5) is arranged. The arrangement is in this case in particular such that the first blocking element (4) is arranged to be movable relative to the valve housing (3) and that the second blocking element (5) is arranged to be movable within the first blocking element (4). The mobility is realized here as a rotatability of the components relative to one another and around the transverse axis (6).
Die Sperrelemente (4, 5) weisen jeweils Mantelflächen (7, 8) auf, die entsprechend von Abschnitten und Segmenten einer Zylinderwandung konturiert sind. Im Bereich der Mantelflächen (7, 8) sind jeweils Ausnehmungen (9, 10) angeordnet.The blocking elements (4, 5) each have lateral surfaces (7, 8), which are contoured correspondingly by sections and segments of a cylinder wall. In the region of the lateral surfaces (7, 8) each recesses (9, 10) are arranged.
Fig. 1 zeigt eine Anordnung des Ventils (1) derart, daß eine Ausströmöffnung (11) des Ventilgehäuses (3) von den Mantelflächen (7, 8) der Sperrelemente (4, 5) verschlossen ist. In diesem Betriebszustand kann kein abzufüllendes Produkt aus der Ausströmöffnung (11) austreten.Fig. 1 shows an arrangement of the valve (1) such that an outflow opening (11) of the valve housing (3) from the lateral surfaces (7, 8) of the locking elements (4, 5) is closed. In this operating state no product to be filled can escape from the outflow opening (11).
Gemäß dem Betriebszustand in Fig. 2 sind die Sperrelemente (4, 5) relativ zueinander und relativ zum Ventilgehäuse (3) um die Querachse (6) herum derart verdreht worden, daß die Ausströmöffnung (11) freigegeben ist. Die Ausnehmungen (9, 10) der Sperrelemente (4, 5) und die Ausströmöffnung (11) überdecken sich hierbei zumindest bereichsweise. Fig. 2 veranschaulicht insbesondere, daß durch eine entsprechende Positionierung der Sperrelemente (4, 5) relativ zueinander und relativ zum Ventilgehäuse (3) sowohl die Größe einer resultierenden Austrittsöffnung (12) als auch die Positionierung einer Flächenmittellinie (13) relativ zum Ventilgehäuse (3) verändert und variiert werden kann. Die Vorgabe der wirksamen Größe der Austrittsöffnung (12) und der Orientierung der Flächenmittellinie (13) kann gemäß der Aus- führungsform in Fig. 1 und Fig. 2 insbesondere dadurch unterstützt werden, daß das erste Sperrelement (4) sowohl mit einer Mantelfläche (7) als auch mit einer Mantelfläche (14) ausgestattet sind, die relativ zueinander in einer Umfangsrichtung mit einem Abstand angeordnet sind und die Ausnehmung (9) begrenzen.According to the operating state in Fig. 2, the locking elements (4, 5) relative to each other and relative to the valve housing (3) have been rotated around the transverse axis (6) around such that the outflow opening (11) is released. The recesses (9, 10) of the locking elements (4, 5) and the outflow opening (11) overlap here at least partially. Fig. 2 illustrates in particular that by an appropriate positioning of the locking elements (4, 5) relative to each other and relative to the valve housing (3) both the size of a resulting outlet opening (12) and the positioning of a surface center line (13) relative to the valve housing (3 ) can be changed and varied. The specification of the effective size of the outlet opening (12) and the orientation of the surface center line (13) can, in accordance with the embodiment in FIGS. 1 and 2, be assisted in particular in that the first blocking element (4) is provided both with a lateral surface (7 ) as well as with a lateral surface (14) are provided, which are arranged relative to each other in a circumferential direction at a distance and the recess (9) limit.
Eine Positionierung der Sperrelemente (4, 5) relativ zueinander und relativ zum Ventilgehäuse (3) kann manuell oder automatisch erfolgen. Bei einer automatischen Positionierung ist insbesondere an die Verwendung von elektrischen oder pneumatischen Positionierelementen gedacht, die entweder direkt oder unter Zwischenschaltung von Kopplungen, Getrieben oder anderen Verbindungseinrichtungen auf die Sperrelemente (4, 5) einwirken.A positioning of the locking elements (4, 5) relative to each other and relative to the valve housing (3) can be done manually or automatically. In the case of an automatic positioning, the use of electrical or pneumatic positioning elements is particularly intended, which act on the blocking elements (4, 5) either directly or with the interposition of couplings, gears or other connecting devices.
Fig. 3 zeigt eine perspektivische Darstellung der beiden voneinander getrennten und aus dem Ventilgehäuse (3) her-ausgenommenen Sperrelemente (4, 5) . Die zylinderartige Gestaltung der Sperrelemente (4, 5) wird hierdurch nochmals verdeutlicht. Insbesondere ist zu erkennen, daß die Sperrelemente (4, 5) jeweils an den Enden der jeweiligen zylindrischen Erstreckungen einen Boden (15, 16) und einen Deckel (17, 18) besitzen. Bei geeigneten Abdichtungen der Sperrelemente (4, 5) relativ zum Ventilgehäuse (3) ist es allerdings nicht erforderlich, daß die Böden (15, 16) und die Deckel (17, 18) eine flächig geschlossene Ausbildung aufweisen, sondern diese können beispielsweise als Führungsring oder andersartig gestaltetes Führungseiement ausgebildet sein.Fig. 3 shows a perspective view of the two separate and from the valve housing (3) her-recessed locking elements (4, 5). The cylindrical design of the locking elements (4, 5) is thereby clarified again. In particular, it can be seen that the locking elements (4, 5) each have at the ends of the respective cylindrical extensions a bottom (15, 16) and a lid (17, 18). With suitable sealing of the locking elements (4, 5) relative to the valve housing (3), however, it is not necessary that the bottoms (15, 16) and the cover (17, 18) have a surface closed training, but these can, for example, as a guide ring or differently designed Führungsseiement be formed.
Die vorstehend erläuterte hülsenartige Ausführungsform stellt eine besondere Ausführungsform einer zylinderartigen Gestaltung der Sperrelemente (4, 5) dar. Zylinderartige Ausbildungen umfassen ebenfalls kegelartige oder kegelstumpfartige Ausbildungen. Die entsprechenden kegel- oder zylinderartigen Gestaltungen können auch teilweise massiv ausgeführt sein, wobei sich vorzugsweise innerhalb der massiven Ausführungsform Durchgangskanäle erstrecken. Alternativ zur Bereitstellung der Ausströmöffnung durch eine geeignete Drehverstellung der Versperrelemente (4, 5) ist es auch möglich, die Größe und/oder die Lage der Ausströmöffnung durch eine axiale Positionierung der Sperrelemente (4, 5) vorzugeben. The above-described sleeve-like embodiment represents a particular embodiment of a cylinder-like design of the locking elements (4, 5). Cylindrical formations also comprise conical or frustoconical designs. The corresponding conical or cylindrical designs may also be made partially solid, preferably extending within the solid embodiment through channels. As an alternative to providing the outflow opening by means of a suitable rotational adjustment of the blocking elements (4, 5), it is also possible to specify the size and / or the position of the outflow opening by an axial positioning of the blocking elements (4, 5).
