Definitions

  • the invention relates to a device for transporting fluid packs through treatment stations, with an endless toothed belt provided with teeth as projections and extending from a feed point to at least one discharge point around a drive wheel and a deflection wheel arranged at a distance therefrom, each with a vertical axis of rotation the packs holding containers arranged in the form of a row and held in engagement with the teeth of the toothed belt are guided through stationary rails on at least part of the closed conveying path.
  • liquid food e.g. As milk or fruit juices
  • pack in packs to transport and to offer the end consumer, which e.g. consist of paper, plastic or a combination of these materials.
  • These packs can have different designs, e.g. be cuboid, tubular or have a combination of these designs.
  • Treatment stations are machine parts or devices or individual devices that perform certain functions at a specific point along a conveyor line along which the packaging is conveyed, or perform activities on the packs that pass them, e.g. Filling, folding, closing, folding, pushing out of the conveyor line, etc.
  • Chains with metal parts are known as transport devices.
  • Containers or roller chains with fastening flanges which are connected to one another in a chain-like manner and to which containers are screwed are also known.
  • These known devices have the disadvantage that they have to be continuously provided with lubricants and maintained. In stainless steel, these devices are difficult and expensive to manufacture.
  • As a result of normal wear and tear, such chains expand or elongate perpendicular to the two axes of the drive wheels, over which these chains are guided. This makes it necessary to readjust the center distance between the two drive wheels, so that this center distance must be changeable.
  • This causes a disadvantageous change in the position of the individual treatment stations relative to one another. For example, the folding station must be kept at a certain distance from the filling station, and if this distance has changed, the treatment stations must also be moved. Correcting the distance between the treatment stations is a serious disadvantage for both the company and the manufacturer.
  • a transport device similar to the type described at the outset is known, in which the containers are clamped to the toothed belt via a coupling pin, so that exact guidance is not possible, which also does not appear necessary because the vials transported there should not be guided to certain stations with comparable precision.
  • guide means can be provided in the region of the deflection wheels, but these are horizontally arranged support surfaces on which the vials slide so that they do not slide down through the through holes in the above-mentioned containers. In places, the containers with extensions grip around the edges of a plate as a guide.
  • the object of the invention is therefore to improve the device of the type described in the introduction in such a way that stable guidance of the plasticizer packs - even if they are filled with plasticizer and open on one side - is made possible from one treatment station to the next with precise positioning.
  • the containers are guided and held against one another in at least one straight strand in a continuous row lying in the conveying direction.
  • the liquid packs are guided precisely and stably through the rails and are also held precisely to the individual treatment stations, including the loading and unloading points. Because the liquid packs are held in the stably guided containers, the conventional means of transport can be used, e.g. the chain timing belts.
  • the packs are guided through stationary rails, it is preferably the straight part of the closed conveying path on which these rails are arranged.
  • the stabilization of the position and the conveying path of the containers is furthermore particularly expediently ensured that, in an embodiment of the invention, two stationary rails are arranged one above the other at a vertical distance on one side of the upright rotating toothed belt and the containers on the other side of the same and in the rails running guide rollers are provided.
  • the advantageous stabilization takes place, so to speak, around the conveyor belt or toothed belt, because the conveyor rollers running in the rails are arranged on one side of the toothed belt and the containers on the other side of the toothed belt are not.
  • the toothed belt is used, so to speak, only as a tension element and is therefore not subject to any stretch.
  • the toothed belt is guided precisely, so that a high stability and exact position are made possible for the containers and the liquid packs arranged in them.
  • a change in the distance between the axles of the drive and deflection wheels in the sense of a correction is not necessary, because stretching of the belt is hardly to be expected. Even if this should have occurred due to the many hours of operation and difficult conditions, this does not affect the exact positioning of the containers, because the containers push each other at a defined distance or width. In this way, a maintenance-free and wear-free transport device is obtained, in which the containers are moved towards one another in pushing operation.
  • the invention is further configured in that the container has a receiving part holding the fluid pack and a flange carrier arranged next to the toothed belt and fastened to the receiving part, to which the guide rollers are rotatably attached in the longitudinal direction at a distance via clamping pieces.
  • the structure of the container thus ensures the best stability.
  • the flange carrier which is provided lying flat against the toothed belt, serves on the one hand as a holder for the container, to the one side of the toothed belt, and on the other hand as a holder for the guide rollers on the opposite side of the toothed belt (in relation to the Receiving part) are arranged.
  • These guide rollers ensure a stable mounting of the flange carrier and thus the receiving part, and consequently also the liquid pack. It is particularly expedient if the clamping pieces have a complementary design to the teeth of the toothed belt and ensure that the containers engage with the toothed belt. Such a construction is particularly space-saving and compensates for the forces occurring in the area and on both sides of the toothed belt on the container through the weights and the drive train.
  • a further embodiment of the invention is also advantageous if the lower guide rollers are provided with conductive support rails in the curved section of the conveyor belt.
  • the stationary guide rails mentioned are only located on the straight section or the straight run of the conveyor line, so that there is a simple and inexpensive production option in terms of production technology, since those in the curved sections usually have a cross-section U-shaped rails are not necessary.
  • a sufficient stability of the guided toothed belt itself has been shown in the curved section, and it has been found that it is probably due to the height of the drive wheel or the height of the deflection wheel on the one hand and the curvature of the toothed belt on the other hand, which is why sufficient stability has been determined.
  • only L-shaped support rails, which guide the lower guide rollers have proven to be advantageous only in the lower region and preferably in cross section.

Description

Die Erfindung betrifft eine Vorrichtung zum Transportieren von Fliessmittelpackungen durch Behandlungsstationen, mit von einer Aufgabestelle bis mindestens zu einer Abgabestelle um ein Antriebs- und ein im Abstand von diesem angeordnetes Umlenkrad mit jeweils vertikaler Drehachse umlaufend vorgesehenem, endlosem, mit Zähnen als Vorsprüngen versehenem Zahnriemen, wobei die Packungen halternde, in Form einer Reihe angeordnete und mit den Zähnen des Zahnriemens in Eingriff gehaltene Behältnisse mindestens auf einem Teil des geschlossenen Förderweges durch stationäre Schienen geführt sind.The invention relates to a device for transporting fluid packs through treatment stations, with an endless toothed belt provided with teeth as projections and extending from a feed point to at least one discharge point around a drive wheel and a deflection wheel arranged at a distance therefrom, each with a vertical axis of rotation the packs holding containers arranged in the form of a row and held in engagement with the teeth of the toothed belt are guided through stationary rails on at least part of the closed conveying path.

Es ist bekannt, flüssige Lebensmittel, z. B. Milch oder Fruchtsäfte, in Packungen zu verpacken, zu transportieren und dem Endverbraucher anzubieten, die z.B. aus Papier, Kunststoff oder einer Kombination dieser Materialien bestehen. Diese Packungen können unterschiedliche Gestaltung haben, z.B. quaderförmig, tubusförmig sein oder Formen einer Kombination dieser Gestaltungen haben.It is known to liquid food, e.g. As milk or fruit juices, to pack in packs, to transport and to offer the end consumer, which e.g. consist of paper, plastic or a combination of these materials. These packs can have different designs, e.g. be cuboid, tubular or have a combination of these designs.

Unter Behandlungsstationen versteht man Maschinenteile bzw. Einrichtungen oder Einzelgeräte, die an einer bestimmten Stelle eines Förderstranges, längs welchem die Verpackungen gefördert werden, gewisse Funktionen ausüben bzw. Tätigkeiten an den an ihnen vorübergeführten Packungen durchführen, z.B. Füllen, Falten, Verschliessen, Umlegen, aus dem Förderstrang herausschieben usw.Treatment stations are machine parts or devices or individual devices that perform certain functions at a specific point along a conveyor line along which the packaging is conveyed, or perform activities on the packs that pass them, e.g. Filling, folding, closing, folding, pushing out of the conveyor line, etc.

Bekannt sind als Transporteinrichtungen Ketten, die Metallteile aufweisen. Bekannt sind auch kettenartig miteinander verbundene Behältnisse oder Rollenketten mit Befestigungsflanschen, an denen Behältnisse angeschraubt sind. Diese bekannten Einrichtungen haben den Nachteil, dass sie mit Schmiermitteln laufend versehen und gewartet werden müssen. In rostfreier Ausfertigung sind diese Einrichtungen schwierig und teuer herzustellen. Durch den normalen Verschleiss erfolgt eine Ausdehnung oder Längung derartiger Ketten senkrecht zu den zwei Achsen der Antriebsräder, über welche diese Ketten geführt sind. Hierdurch wird ein Nachstellen des Achsabstandes zwischen den beiden Antriebsrädern erforderlich, so dass dieser Achsabstand veränderbar sein muss. Dies wiederum bedingt in nachteiliger Weise eine Veränderung der Position der einzelnen Behandlungsstationen zueinander. Beispielsweise muss die Faltstation in bestimmtem Abstand zur Einfüllstation gehalten werden, und wenn sich dieser Abstand geändert hat, müssen auch die Behandlungsstationen verschoben werden. Dieses Korrigieren des Abstandes zwischen den Behandlungsstationen bedeutet sowohl für den Betrieb als auch für den Hersteller einen schwerwiegenden Nachteil.Chains with metal parts are known as transport devices. Containers or roller chains with fastening flanges which are connected to one another in a chain-like manner and to which containers are screwed are also known. These known devices have the disadvantage that they have to be continuously provided with lubricants and maintained. In stainless steel, these devices are difficult and expensive to manufacture. As a result of normal wear and tear, such chains expand or elongate perpendicular to the two axes of the drive wheels, over which these chains are guided. This makes it necessary to readjust the center distance between the two drive wheels, so that this center distance must be changeable. This in turn causes a disadvantageous change in the position of the individual treatment stations relative to one another. For example, the folding station must be kept at a certain distance from the filling station, and if this distance has changed, the treatment stations must also be moved. Correcting the distance between the treatment stations is a serious disadvantage for both the company and the manufacturer.

Aus der FR-A-2215369 ist eine Transportvorrichtung ähnlich der eingangs beschriebenen Art bekannt, bei welcher die Behälter über einen Kupplungsstift am Zahnriemen festgeklemmt sind, so dass eine exakte Führung nicht möglich ist, die auch deshalb nicht erforderlich erscheint, weil die dort transportierten Phiolen nicht vergleichbar präzise an bestimmte Stationen geführt werden sollen. Im Bereich der Umlenkräder können im bekannten Falle zwar Führungsmittel vorgesehen sein, hierbei handelt es sich aber um horizontal angeordnete Stützflächen, auf welchen die Phiolen gleiten, damit sie durch die durchgehenden Löcher in den erwähnten Behältern nicht nach unten hindurchrutschen. Streckenweise umgreifen die Behältnisse mit Fortsätzen die Kanten einer Platte als Führung.From FR-A-2215369 a transport device similar to the type described at the outset is known, in which the containers are clamped to the toothed belt via a coupling pin, so that exact guidance is not possible, which also does not appear necessary because the vials transported there should not be guided to certain stations with comparable precision. In the known case, guide means can be provided in the region of the deflection wheels, but these are horizontally arranged support surfaces on which the vials slide so that they do not slide down through the through holes in the above-mentioned containers. In places, the containers with extensions grip around the edges of a plate as a guide.

Aufgabe der Erfindung ist daher die Verbesserung der Vorrichtung der eingangs bezeichneten Art dahingehend, dass eine stabile Führung der Fliessmittelpackungen - selbst wenn sie mit Fliessmittel gefüllt und einseitig offen sind - unter genauer Positionierung von einer Behandlungsstation zur nächsten ermöglicht ist.The object of the invention is therefore to improve the device of the type described in the introduction in such a way that stable guidance of the plasticizer packs - even if they are filled with plasticizer and open on one side - is made possible from one treatment station to the next with precise positioning.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Behältnisse in mindestens einem geraden Trum in einer fortlaufenden, in Förderrichtung liegenden Reihe aneinanderliegend geführt und gehalten sind. Durch die Schienen werden die Flüssigkeitspackungen präzise und stabil geführt und auch zu den einzelnen Behandlungsstationen exakt gehalten geführt, einschliesslich Aufgabestelle und Abgabestelle. Weil die Flüssigkeitspackungen in den stabil geführten Behältnissen gehaltert sind, können die herkömmlichen Transportmittel eingesetzt werden, z.B. die Kettenzahnriemen. Bei der Führung der Packungen durch stationäre Schienen handelt es sich vorzugsweise um den geraden Teil des geschlossenen Förderweges, an welchen diese Schienen angeordnet sind. Durch das weiterhin erfindungsgemäss vorgeschlagene Aneinanderliegen der geführten Reihe von Flüssigkeitspackungen erreicht man ein Verschieben der Behältnisse mit Hilfe des Zahnriemens und erlaubt den exakten Vorlaufschritt über den Schubbetrieb, der sogar von einer etwaigen Längenausdehnung des Transportbandes unabhängig ist. Dadurch können Faltverschlüsse an mit Flüssigkeit gefüllten und zunächst noch einseitig offenen Packungen verschlossen werden, wobei die Flüssigkeitsabdichtung durch exakt an die richtige Stelle legbare Siegelnähte erfolgen kann. Dies alles gelingt deshalb, weil die Führung der Behältnisse auf dem Förderweg des Zahnriemens präzise und genau erfolgt.This object is achieved according to the invention in that the containers are guided and held against one another in at least one straight strand in a continuous row lying in the conveying direction. The liquid packs are guided precisely and stably through the rails and are also held precisely to the individual treatment stations, including the loading and unloading points. Because the liquid packs are held in the stably guided containers, the conventional means of transport can be used, e.g. the chain timing belts. When the packs are guided through stationary rails, it is preferably the straight part of the closed conveying path on which these rails are arranged. Due to the fact that the guided row of liquid packs, which is further proposed according to the invention, one moves the containers with the help of the toothed belt and allows the exact advance step via the pushing operation, which is even independent of any length extension of the conveyor belt. As a result, folding closures can be closed on packages filled with liquid and initially still open on one side, wherein the liquid can be sealed by sealing seams which can be placed exactly in the right place. All of this is possible because the containers are guided precisely and precisely along the conveying path of the toothed belt.

Die Stabilisierung der Lage und des Förderweges der Behältnisse wird weiterhin besonders zweckmässig dadurch gewährleistet, dass in Ausgestaltung der Erfindung in vertikalem Abstand übereinander zwei stationäre Schienen auf der einen Seite des hochkant umlaufenden Zahnriemens und die Behältnisse auf der anderen Seite desselben angeordnet und mit in den Schienen laufenden Führungsrollen versehen sind. Die vorteilhafte Stabilisierung erfolgt sozusagen um den Förderriemen oder Zahnriemen herum, weil die in den Schienen laufenden Förderrollen auf der einen Seite des Zahnriemens und die Behältnisse auf der anderen Seite des Zahnriemens angeordnet sind. Der Zahnriemen wird sozusagen nur als Zugelement verwendet und unterliegt somit praktisch keiner Dehnung. Der Zahnriemen wird präzise geführt, so dass für die Behältnisse und die in diesen angeordneten Flüssigkeitspackungen eine hohe Stabilität und exakte Position ermöglicht sind. Eine Veränderung des Abstandes zwischen den Achsen der Antriebs- und Umlenkräder im Sinne einer Korrektur ist nicht erforderlich, denn eine Dehnung des Riemens ist kaum zu erwarten. Selbst wenn eine solche aber durch sehr viele Betriebsstunden und schwierige Verhältnisse doch aufgetreten sein sollte, wirkt sich diese auf das genaue Positionieren der Behältnisse nicht aus, denn die Behältnisse schieben sich gegenseitig in hierdurch bzw. durch ihre Breite definiertem Abstand. Auf diese Weise erhält man eine wartungsfreie und verschleissfreie Transporteinrichtung, bei welcher die Behältnisse im Schiebebetrieb in Anlage aneinander vorbewegt werden.The stabilization of the position and the conveying path of the containers is furthermore particularly expediently ensured that, in an embodiment of the invention, two stationary rails are arranged one above the other at a vertical distance on one side of the upright rotating toothed belt and the containers on the other side of the same and in the rails running guide rollers are provided. The advantageous stabilization takes place, so to speak, around the conveyor belt or toothed belt, because the conveyor rollers running in the rails are arranged on one side of the toothed belt and the containers on the other side of the toothed belt are not. The toothed belt is used, so to speak, only as a tension element and is therefore not subject to any stretch. The toothed belt is guided precisely, so that a high stability and exact position are made possible for the containers and the liquid packs arranged in them. A change in the distance between the axles of the drive and deflection wheels in the sense of a correction is not necessary, because stretching of the belt is hardly to be expected. Even if this should have occurred due to the many hours of operation and difficult conditions, this does not affect the exact positioning of the containers, because the containers push each other at a defined distance or width. In this way, a maintenance-free and wear-free transport device is obtained, in which the containers are moved towards one another in pushing operation.

Vorteilhaft ist die Erfindung weiter dadurch ausgestaltet, dass das Behältnis ein die Fliessmittelpackung halterndes Aufnahmeteil und einen neben dem Zahnriemen angeordneten, am Aufnahmeteil befestigten Flanschträger aufweist, an welchem in seiner Längsrichtung im Abstand über Klemmstücke die Führungsrollen drehbeweglich angebracht sind. Der Aufbau des Behältnisses gewährleistet hierdurch die beste Stabilität. In raumsparender Weise dient der Flanschträger, der flach am Zahnriemen anliegend vorgesehen wird, einerseits als Halterung für das Behältnis, und zwar zur einen Seite des Zahnriemens hin, und andererseits als Halterung für die Führungsrollen, die auf der gegenüberliegenden Seite vom Zahnriemen (im Verhältnis zum Aufnahmeteil) angeordnet sind. Diese Führungsrollen sorgen für eine stabile Halterung des Flanschträgers und damit des Aufnahmeteiles, folglich auch der Flüssigkeitspackung. Besonders zweckmässig ist es dabei, wenn die Klemmstücke komplementäre Gestaltung zu den Zähnen des Zahnriemens haben und den Eingriff der Behältnisse mit dem Zahnriemen besorgen. Ein solcher Aufbau ist besonders raumsparend und kompensiert die im Bereich und auf beiden Seiten des Zahnriemens am Behältnis auftretenden Kräfte durch die Gewichte und den Antriebszug.Advantageously, the invention is further configured in that the container has a receiving part holding the fluid pack and a flange carrier arranged next to the toothed belt and fastened to the receiving part, to which the guide rollers are rotatably attached in the longitudinal direction at a distance via clamping pieces. The structure of the container thus ensures the best stability. In a space-saving manner, the flange carrier, which is provided lying flat against the toothed belt, serves on the one hand as a holder for the container, to the one side of the toothed belt, and on the other hand as a holder for the guide rollers on the opposite side of the toothed belt (in relation to the Receiving part) are arranged. These guide rollers ensure a stable mounting of the flange carrier and thus the receiving part, and consequently also the liquid pack. It is particularly expedient if the clamping pieces have a complementary design to the teeth of the toothed belt and ensure that the containers engage with the toothed belt. Such a construction is particularly space-saving and compensates for the forces occurring in the area and on both sides of the toothed belt on the container through the weights and the drive train.

Eine weitere Ausgestaltung der Erfindung ist ferner günstig, wenn im gekrümmten Abschnitt des Transportbandes die unteren Führungsrollen leitende Stützschienen vorgesehen sind. Für den Betrieb hat es sich als ausreichend erwiesen, wenn die genannten stationären Führungsschienen sich jeweils nur auf der geraden Strecke bzw. dem geraden Trum des Förderstranges befinden, so dass herstellungstechnisch eine einfache und preiswerte Fertigungsmöglichkeit besteht, weil in den gekrümmten Abschnitten solche im Querschnitt meist U-förmig ausgestaltenen Schienen nicht notwendig sind. Im gekrümmten Abschnitt hat sich eine hinreichend grosse Stabilität des geführten Zahnriemens selbst gezeigt, und man hat herausgefunden, dass es wohl an der Höhe des Antriebsrades bzw. der Höhe des Umlenkrades einerseits sowie der Krümmung des Zahnriemens andererseits liegt, weshalb eine ausreichende Stabilität festgestellt wurde. Um diese aber noch weiter zu verbessern und dennoch praktische Herstellungsmöglichkeiten der erfindungsgemässen Vorrichtung vorzusehen, haben sich nur im unteren Bereich und vorzugsweise im Querschnitt nur L-förmige Stützschienen als günstig erwiesen, welche die unteren Führungrollen leiten.A further embodiment of the invention is also advantageous if the lower guide rollers are provided with conductive support rails in the curved section of the conveyor belt. For operation, it has proven to be sufficient if the stationary guide rails mentioned are only located on the straight section or the straight run of the conveyor line, so that there is a simple and inexpensive production option in terms of production technology, since those in the curved sections usually have a cross-section U-shaped rails are not necessary. A sufficient stability of the guided toothed belt itself has been shown in the curved section, and it has been found that it is probably due to the height of the drive wheel or the height of the deflection wheel on the one hand and the curvature of the toothed belt on the other hand, which is why sufficient stability has been determined. However, in order to improve this still further and still provide practical manufacturing options for the device according to the invention, only L-shaped support rails, which guide the lower guide rollers, have proven to be advantageous only in the lower region and preferably in cross section.

Zum Aufgeben bzw. Abnehmen der geförderten Gegenstände ist es zweckmässig, wenn an mindestens einer Stelle des Förderstranges senkrecht zu dessen Längsrichtung angetrieben bewegbare Kolbeneinrichtungen angeordnet sind. Diese können in Richtung senkrecht zur Förderrichtung, vorzugsweise vertikal, von oben nach unten oder umgekehrt in den Förderstrang mehr oder weniger tief hineingeschoben werden, um hierbei das Fördergut herauszuschieben oder beiseite zu ziehen.For loading or unloading the conveyed objects, it is expedient if movably movable piston devices are arranged at at least one point on the conveying strand perpendicular to its longitudinal direction. These can be pushed more or less deeply in the direction perpendicular to the conveying direction, preferably vertically, from top to bottom or vice versa, in order to push out the conveyed material or pull it aside.

Zur Halterung des Fördergutes, vorzugsweise der Flüssigkeitspackung, hat es sich bei weiterer Ausgestaltung der Erfindung als besonders vorteilhaft gezeigt, wenn das Aufnahmeteil des Behältnisses einen etwa runden Innenquerschnitt mit ein Viereck aufspannenden, am Innenrand befindlichen Ausnehmungen und mit neben letzteren angebrachten Stiften aufweist. Die Transporteinrichtung gemäss der Erfindung ist nämlich besonders günstig anwendbar auf im Querschnitt im allgemeinen runde Flüssigkeitspackungen, die an einem, vorzugsweise dem unteren Ende geschlossen sind und am gegenüberliegenden oberen Ende offen sind. Diese Behältnisse können längs eines kreisförmigen Innenrandes in das Aufnahmeteil hereingeschoben und über die Stifte geführt, vorzugsweise drehfest gehaltert und festgelegt werden. Hierdurch wird die hohe Stabilität und die exakte Position der in den Behältnissen geführten Packungen optimal gestaltet.To hold the material to be conveyed, preferably the liquid pack, it has been shown to be particularly advantageous in a further embodiment of the invention if the receiving part of the container has an approximately round inner cross section with a square spanning recesses located on the inner edge and with pins attached next to the latter. The transport device according to the invention is namely particularly advantageously applicable to liquid packs which are generally round in cross section and which are closed at one end, preferably the lower end, and are open at the opposite upper end. These containers can be pushed into the receiving part along a circular inner edge and guided over the pins, preferably held and fixed in a rotationally fixed manner. As a result, the high stability and the exact position of the packs guided in the containers are optimally designed.

Wenn man ferner vorsieht, dass die Führungsrollen aus Kunststoff und die Führungsschienen aus Metall bestehen, dann erhält man eine vollkommen schmierfreie Transporteinrichtung, die zudem noch den Vorteil der Geräuscharmut hat. Trotz dieser günstigen Eigenschaften werden die synchrone Bewegung der einzelnen Behältnisse zueinander und der genaue Abstand und damit die exakte Positionierung der Behältnisse bzw. der Flüssigkeitspackungen unter den Behandlungsstationen gewährleistet.If you also provide that the guide rollers made of plastic and the guide rails made of metal, then you get a completely lubrication-free transport device, which also has the advantage of low noise. Despite these favorable properties, the synchronous movement of the individual containers to one another and the exact spacing and thus the exact positioning of the containers or the liquid packs under the treatment stations are ensured.

Man erkennt aus der Draufsicht der Transporteinrichtung in Figur 1 rechts das mit Speichen versehene Antriebsrad 1, welches durch das in Figur 2 rechts dargestellte Schrittschaltgetriebe 2 für den Antrieb der vertikalen Achse 34 dieses Antriebsrades 1 angetrieben ist. Aus Figur 2 erkennt man auch das mit dem schematisch angedeuteten Fuss 4 versehene Gestell 3, auf welchem die Tischplatte 16 ruht. In den Figuren 1 und 2 befindet sich auf der dem Antriebsrad 1 gegenüberliegenden Seite im Abstand B der vertikalen Drehachsen 34 zueinander das Umlenkrad 5, welches ebenfalls als Speichenrad ausgebildet ist und vorzugsweise aus Kunststoff besteht, während das Antriebsrad aus Metall gefertigt sein sollte. Der in den Figuren 1 bis 5 gezeigte Zahnriemen 6 als Transportband besteht ebenfalls aus Kunststoff und ist somit flexibel, so dass er selbst als Trägerelement für die Flüssigkeitspackungen 25 nicht verwendbar ist.One can see from the top view of the transport device in FIG. 1 on the right the drive wheel 1 provided with spokes, which is driven by the stepping transmission 2 shown on the right in FIG. 2 for driving the vertical axis 34 of this drive wheel 1. FIG. 2 also shows the frame 3 provided with the schematically indicated foot 4, on which the table top 16 rests. In FIGS. 1 and 2, on the side opposite the drive wheel 1 at a distance B from the vertical axes of rotation 34 to one another, the deflection wheel 5, which is also designed as a spoke wheel and preferably consists of plastic, while the drive wheel should be made of metal. The toothed belt 6 shown in FIGS. 1 to 5 as a conveyor belt also consists of plastic and is therefore flexible, so that it itself cannot be used as a carrier element for the liquid packs 25.

Deshalb sind Behältnisse 7 vorgesehen, mit deren Hilfe um den Zahnriemen 6 herum eine Stabilisierung der Packungen 25 erreicht ist. In den Figuren 1 und 2 sieht man, dass der Zahnriemen 6 in Förderrichtung des Pfeiles 22 (in Figur 1 im Uhrzeigersinn) bewegt wird, und zwar von der Aufgabestelle 32 in Figur 1 nach rechts zunächst längs des geraden oberen Trums 41, dann an dessen rechtem Ende anschliessend über den gekrümmten Abschnitt 42 zum Anfang des unteren geraden Trums 41', welches etwa an der Abgabestelle 33 endet, um hier wieder in den linken gekrümmten Abschnitt 42 überzugehen, dessen in Transportrichtung vorderes Ende dann wieder an den Anfang des oberen geraden Trums 41 bei der Aufgabestelle 32 anschliesst.Containers 7 are therefore provided, with the aid of which the packs 25 are stabilized around the toothed belt 6. In FIGS. 1 and 2 it can be seen that the toothed belt 6 is moved in the conveying direction of the arrow 22 (clockwise in FIG. 1), namely from the feed point 32 in FIG. 1 to the right first along the straight upper run 41, then on the latter right end then via the curved section 42 to the beginning of the lower straight run 41 ', which ends approximately at the delivery point 33, in order to merge here again into the left curved section 42, the front end of which in the transport direction then returns to the beginning of the upper straight run 41 connects to the drop point 32.

In den Figuren 1 und 2 sind auch zwei Behandlungsstationen, nämlich die Schweiss- und Verschliessstationen 29 und 20' gezeigt, deren Abstand D voneinander in Figur 1 angedeutet ist. In dieser Figur ist auch der Abstand C zwischen zwei Zähnen 61 des Zahnriemens 6 sowie die Breite E eines Behältnisses 7 gezeigt. Man erkennt ferner, dass im Bereich der geraden Trums 41, 41' die Behältnisse 7 in einer Reihe angeordnet und im Schiebebetrieb in Anlage aneinander vorgesehen sind, während in den gekrümmten Abschnitten 42 die Anlage der einzelnen Behältnisse zueinander aufgehoben ist, weil der Aussenumfang grösser als der des gekrümmten Zahnriemens 6 ist.1 and 2 also show two treatment stations, namely the welding and sealing stations 29 and 20 ', the distance D from which is indicated in FIG. 1. The distance C between two teeth 61 of the toothed belt 6 and the width E of a container 7 are also shown in this figure. It can also be seen that in the area of the straight runs 41, 41 'the containers 7 are arranged in a row and are provided in abutment against one another during pushing operation, while in the curved sections 42 the abutment of the individual containers with respect to one another is canceled because the outer circumference is greater than that of the curved toothed belt 6.

Man erkennt besonders deutlich auf Figur 1 auch die Führungen für die Behältnisse 7 in Gestalt stationärer Schienen 18, die sich nur im Bereich der geraden Trums 41, 41' finden, nämlich beispielsweise in Figur 1 bei dem oberen geraden Trum 41 von der durch den Pfeil 20 bis zu der durch den Pfeil 21 gekennzeichneten Stelle.The guides for the containers 7 in the form of stationary rails 18, which are found only in the area of the straight runs 41, 41 ', can be seen particularly clearly in FIG. 1, namely, for example, in FIG. 1 for the upper straight run 41 from the one indicated by the arrow 20 to the point indicated by arrow 21.

Die Anordnung und Anbringung der Behältnisse 7 am Zahnriemen 6 ist in Drauf- bzw. Seitenansicht zwar teilweise schon aus den Figuren 1 und 2 ersichtlich, geht aber besonders deutlich aus den übrigen Figuren 3 bis 5 hervor.The arrangement and attachment of the containers 7 on the toothed belt 6 can be seen in part from the top or side view from FIGS. 1 and 2, but is particularly clear from the remaining FIGS. 3 to 5.

In Figur 3 sieht man das Behältnis 7 vergrössert dargestellt. Es besteht aus dem mit rundem Innenquerschnitt am Innenrand 43 versehenen Aufnahmeteil 12, an welchem unten an den in den Figuren 5 und 6 gezeigten Stellen Stifte 11 herausstehen, Metallstifte, die vorzugsweise in das Aufnahmteil 12 oben eingeschraubt sind. Das mithin im wesentlichen ring-förmige Aufnahmeteil 12 ist über Schrauben an einem Flanschträger 13 befestigt, der als rechteckige, längliche Platte zu denken ist, deren Ebene im wesentlichen parallel zur benachbarten Teilebene des Zahnriemens 6 liegt. Vorzugsweise kann die hintere Fläche des Flanschträgers 13 direkt auf der Vorderfläche des Zahnriemens 6 anliegend vorgesehen sein. Die Kopplung dieses Flanschträgers 13 mit dem Zahnriemen 6 erfolgt über Klemmstücke 8 und 9, die jeweils über zwei hintereinander angeordnete Schrauben 10 im Abstand übereinander angeordnet und am Flanschträger 13 befestigt sind. Zwischen den hintereinanderliegenden Schrauben 10 befinden sich in den Klemmstücken 8 und 9 Löcher für die Aufnahme jeweils eines Trägerbolzens 14, der nach hinten auf der bezüglich des Zahnriemens 6 dem Aufnahmeteil bzw. Behältnis 7 gegenüberliegenden Seite herausteht und frei drehbar die Führungsrolle 15 haltert, so dass bei vertikal stehend gedachten Achsen 34 des Antriebsrades 1 und Umlenkrades 5 der Abstand zwischen der unteren Führungsrolle und der oberen Führungsrolle 15 ebenfalls in vertikaler Richtung liegt.In Figure 3, the container 7 is shown enlarged. It consists of the receiving part 12 provided with a round inner cross section on the inner edge 43, from which pins 11 protrude at the bottom at the points shown in FIGS. 5 and 6, metal pins which are preferably screwed into the receiving part 12 at the top. The essentially ring-shaped receiving part 12 is fastened by screws to a flange carrier 13, which is to be thought of as a rectangular, elongated plate, the plane of which is essentially parallel to the adjacent sub-plane of the toothed belt 6. The rear surface of the flange carrier 13 can preferably be provided so as to lie directly on the front surface of the toothed belt 6. The coupling of this flange carrier 13 to the toothed belt 6 takes place via clamping pieces 8 and 9, which are each arranged at a distance above one another by means of two screws 10 arranged one behind the other and are fastened to the flange carrier 13. Between the screws 10 one behind the other there are holes in the clamping pieces 8 and 9 for receiving a respective carrier bolt 14 which protrudes towards the rear on the side opposite the receiving part or container 7 with respect to the toothed belt 6 and which holds the guide roller 15 so that it can rotate freely with axially standing axes 34 of the drive wheel 1 and deflection wheel 5, the distance between the lower guide roller and the upper guide roller 15 is also in the vertical direction.

Aus Figur 3 erkennt man auch die im vertikalen Abstand über eine Stange 17 miteinander verbundenen, im Querschnitt U-förmigen Führungsschienen 18, deren untere an der Tischplatte 16 befestigt ist und deren obere über die Stange 17 einerseits und den Querträger 23 andererseits mit der Tischplatte 16 und damit dem Gestell 3 verbunden ist. Die offenen Enden der beiden U-förmigen Führungsschienen 18 sind einander zugerichtet, so dass die beiden Führungsrollen 15 von innen in diese Schienen 18 eingreifen können. Die Führungsrollen 15 bestehen vorzugsweise aus Kunststoff und können daher schmierfrei und geräuscharm in den geraden Führungsschienen 18 gehalten sein. Über dem unteren rechten Ende der Tischplatte 16 ist in Figur 3 eine Schiene 31 zu sehen, über welche die in Figur 3 nicht gezeigte Flüssigkeitspackung gleitend geschoben werden kann.FIG. 3 also shows the guide rails 18, which are connected to one another at vertical spacing via a rod 17 and are U-shaped in cross section, the lower ones of which are fastened to the table top 16 and the upper ones of which are attached to the table top 16 via the rod 17 on the one hand and the cross member 23 on the other hand and is connected to the frame 3. The open ends of the two U-shaped guide rails 18 face each other so that the two guide rollers 15 can engage in these rails 18 from the inside. The guide rollers 15 are preferably made of plastic and can therefore be kept in the straight guide rails 18 in a lubrication-free and low-noise manner. A rail 31 can be seen in FIG. 3 above the lower right end of the table top 16, over which the liquid pack, not shown in FIG. 3, can be slid.

In Figur 4 ist diese Führungsschiene 31 heb- und senkbar vorgesehen und wird über den Kolben 40 bewegt. Da die Darstellung der Figur 4 eine Schnittansicht im gekrümmten Abschnitt 42 des Förderstranges ist, gibt es hier die beiden Führungsschienen 18 nicht. Vielmehr ist hier lediglich eine auf der Tischplatte 16 befestigte Stützschiene 18' unten befestigt, so dass sich die untere Führungsrolle 15 auf dieser so abstützen kann, dass das Behältnis 7 auch im Bereich des Aussenumfanges des Antriebsrades 1, d.h. des gekrümmten Abschnittes 42 des Förderstranges, einwandfrei stabil gehalten ist.In FIG. 4, this guide rail 31 can be raised and lowered and is moved via the piston 40. Since the illustration in FIG. 4 is a sectional view in the curved section 42 of the conveyor line, there are no two guide rails 18 here. Rather, it is just here a support rail 18 'fastened on the table top 16 attached below, so that the lower guide roller 15 can be supported on it in such a way that the container 7 is kept perfectly stable even in the region of the outer circumference of the drive wheel 1, ie the curved section 42 of the conveyor line .

Gemäss Figur 5 ist das Aufnahmeteil 12 innen rund, wie der Kreis 24 zeigt. In der Draufsicht der Figur 6 und im Querschnitt der Figur 3 erkennt man ferner, dass das Aufnahmeteil oben mit einem konusförmigen Einführstück versehen ist, um die Aufgabe der Flüssigkeitspackung in das Behältnis 7 an der Station 32 zu erleichtern. Längs vier Linien, wo die Stifte 11 in das Aufnahmeteil 12 eingesteckt und befestigt oder eingeschraubt sind, wird die zunächst im Querschnitt runde Flüssigkeitspackung geführt und drehfest gehalten.According to FIG. 5, the receiving part 12 is round on the inside, as the circle 24 shows. In the plan view of FIG. 6 and in the cross section of FIG. 3, it can also be seen that the receiving part is provided at the top with a conical insertion piece in order to facilitate the task of packing the liquid into the container 7 at the station 32. The liquid pack, which is initially round in cross section, is guided and held in a rotationally fixed manner along four lines, where the pins 11 are inserted and fastened or screwed into the receiving part 12.

In Figur 5 sieht man zunächst einen Schnitt durch den Zahnriemen 6, auf dessen oberer Seite sich das Aufnahmeteil 12 mit angebrachtem Flanschträger befindet, während gegenüberliegend das Klemmstück 8 bzw. 9 und über den Trägerbolzen 14 die drehbar daran angebrachte Führungsrolle 15 gezeigt sind. In dieser Darstellung sind die Zähne 61 des Zahnriemens 6 besonders deutlich ersichtlich, und das hier gezeigte Klemmstück 8 bzw. 9 weist einen komplementären Vorsprung 81 auf, welcher genau in die Zahnlücke des Zahnriemens 6 passt und auf diese Weise eine synchrone Kopplung des Behältnisses 7 mit dem Zahnriemen 6 garantiert. Der Abstand A der hinteren Fläche des Flanschträgers 13 zur nächstliegend angeordneten Fläche des Vorsprunges 81 kann entweder mit leichtem Übermass oder mit leichtem Untermass bezüglich der Riemendicke an dieser Stelle ausgebildet sein. Beispielsweise kann der Abstand A mit 1/10 mm Untermass bezüglich der Dicke des Zahnriemens 6 ausgestaltet sein. Damit erhält man eine Pressung durch die Schrauben 10, welche den Flanschträger 13 mit den Klemmstücken 8 und 9 verbinden. Andererseits könnte man aber auch ein Spiel von 1/10 mm im Bereich des Abstandes A vorsehen, wenn der Zahnriemen 6 nicht verformt werden soll. Bei einer bevorzugten praktischen Ausführungsform der Erfindung hat sich gezeigt, dass das Behältnis 7 besonders dann einen klaren und definierten Halt am Zahnriemen 6 erhält, wenn eine Pressung von 1/10 mm vorgegeben wird. Dieses Mass von 1/10 mm ist eine absolute Grösse.5 shows a section through the toothed belt 6, on the upper side of which the receiving part 12 with the attached flange carrier is located, while the clamping piece 8 or 9 is shown opposite and the rotatable guide roller 15 is shown above the carrier bolt 14. In this illustration, the teeth 61 of the toothed belt 6 can be seen particularly clearly, and the clamping piece 8 or 9 shown here has a complementary projection 81 which fits exactly into the tooth gap of the toothed belt 6 and in this way a synchronous coupling of the container 7 the timing belt 6 guaranteed. The distance A between the rear surface of the flange carrier 13 and the surface of the projection 81 arranged next to it can either be designed with a slight oversize or with a slight undersize with regard to the belt thickness at this point. For example, the distance A can be designed with 1/10 mm undersize with respect to the thickness of the toothed belt 6. This gives a pressure by the screws 10, which connect the flange support 13 to the clamping pieces 8 and 9. On the other hand, one could also provide a play of 1/10 mm in the area of the distance A if the toothed belt 6 is not to be deformed. In a preferred practical embodiment of the invention, it has been shown that the container 7 receives a clear and defined hold on the toothed belt 6 especially when a pressure of 1/10 mm is specified. This measure of 1/10 mm is an absolute size.

Im Betrieb wird vorzugsweise eine zunächst tubusförmige, mit einem Deckel unten verschlossene Packung 25 an der Aufgabestelle 32 in das Aufnahmeteil 12 hereingeschoben und längs der Stifte 11 nach innen in das Behältnis soweit heruntergeschoben, dass bei der Darstellung der Figuren 2 bis 4 der Boden der Packung 25 auf der Stützschiene 31 ruht, während die zylindrischen Aussenwände der Packung durch die Anlage der Stifte 11 längs der Linie 28 (Figur 6) verdrehfest und mit leichter Klemmung gehalten sind. Es erfolgt dann beim Fortlauf der Transporteinrichtung in Richtung des Pfeiles 22 an nicht gezeigten Behandlungsstationen das Befüllen der tubusförmigen Packung mit einer Flüssigkeit und schliesslich das Verschweissen und Verschliessen in den Stationen 29 und 20', bevor letztlich die Abgabe an der Stelle 33 erfolgt. Das Verschliessen wird bei dieser bevorzugten Ausführungsform über eine Klotzbodenausgestaltung vorgenommen, so dass sich die in gestrichelter Gestalt in Figur 6 gezeigte Position der Packung 25 ergibt. Man erkennt hier die von oben nach unten in der Mite verlaufende Längsnaht, die durch nicht gezeigte Schweissbakken dichtend verschlossen ist. Der Schweiss- und Verschliessstation nachgeschaltet sind an sich bekannte Behandlungsstationen, mit deren Hilfe die herausstehenden Dreiecklappen auf Seitenwände oder die Deckelwand umgelegt und dort befestigt werden.In operation, an initially tubular packing 25, closed with a lid at the bottom, is pushed into the receiving part 12 at the feed point 32 and pushed inward along the pins 11 to the extent that the bottom of the packing is shown in FIGS. 2 to 4 25 rests on the support rail 31, while the cylindrical outer walls of the pack are held against rotation and held with slight clamping by the contact of the pins 11 along the line 28 (FIG. 6). When the transport device continues in the direction of arrow 22, the tubular package is filled with a liquid at treatment stations (not shown) and finally sealed and sealed in stations 29 and 20 'before finally being dispensed at point 33. In this preferred embodiment, the closure is carried out by means of a block bottom configuration, so that the position of the pack 25 shown in dashed lines in FIG. 6 results. One can see here the longitudinal seam running from top to bottom in the middle, which is sealed by welding baffles, not shown. The welding and sealing station is followed by treatment stations known per se, with the aid of which the protruding triangular flaps are folded over onto side walls or the cover wall and fastened there.

Weil die Packung vor und nach dem Befüllen rund ist, ist das Aufnahmeteil im Querschnitt kreisförmig, wie in Figur 5 der Kreis 24 zeigt. Weil aber danach durch das Verschliessen gemäss Klotzboden zumindest an diesem oberen Ende der Packung sich schliesslich eine vierecke Gestalt ergibt, sind an den Innenkreis 24 anschliessend vier Ausnehmungen 26 dort eingebracht, wo die vier Ecken der Packung sich aus der Rundung ergeben und Platz innerhalb des Aufnahmeteils 12 benötigen. Dennoch wird der untere übrige Teil der auf diese Weise verschlossenen Packung nach wie vor längs der Grenze geführt, die in Figur 6 durch den Innenkonus 27 angedeutet ist. Über diesen stehen die Stifte 11 längs der kleinen Bereiche 28 leicht vor, so dass durch die Stifte ein gewisser Eindruck an der Packung 25 hier ausgeübt wird. Dies dient gleichzeitig der Längsführung der Packung 25 in dem Behälter 7 wie auch einer Verdrehhinderung. Die die Packung 25 berührende Innenkante der Stifte 11 ist mit 28 bezeichnet und steht leicht über den Innenkreis 27 nach innen hinein, vorzugsweise um 1 mm jeweils. Man erkennt übrigens aus den Figuren 5 und 6 auch, dass die Ausnehmungen 26 sich jeweils neben dem Ort der Stifte 11 befinden, so dass sich hier keine gegenseitige Störung ergibt.Because the pack is round before and after filling, the receiving part is circular in cross section, as shown in FIG. 5 by the circle 24. However, because afterwards, by closing the block bottom, at least at this upper end of the pack, a square shape finally results, four recesses 26 are subsequently made in the inner circle 24 where the four corners of the pack result from the rounding and space within the receiving part 12 need. Nevertheless, the lower remaining part of the package sealed in this way is still guided along the boundary, which is indicated in FIG. 6 by the inner cone 27. The pins 11 protrude slightly above these along the small areas 28, so that a certain impression is exerted on the pack 25 here by the pins. This simultaneously serves to guide the package 25 in the container 7 as well as to prevent rotation. The inner edge of the pins 11 touching the pack 25 is designated 28 and projects slightly inwards over the inner circle 27, preferably by 1 mm in each case. It can also be seen from FIGS. 5 and 6 that the recesses 26 are each located next to the location of the pins 11, so that there is no mutual interference here.
