Abstract

The packaging material is transported as a sheet of material carried on a conveyor chain which includes e.g. rollers or sliders (15) running in guide rails (13, 14). The outside of the guidance system is kept open at least locally, so that the upper and lower guide rails are accessible for cleaning. The guide rails are fastened to a holding profile (18) with clearance. A number of stand-off fasteners (17) which are spaced apart, hold the guide rails. This makes the spaces between fastening components accessible.

Description

Die Erfindung betrifft eine Verpackungsmaschine, insbesondere eine Rollen- oder Tiefziehmaschine, eine Schalenversiegelungsmaschine oder dergleichen nach dem Oberbegriff des Anspruchs 1.The invention relates to a packaging machine, in particular a roller or thermoforming machine, a tray sealing machine or the like according to the preamble of claim 1.

Verpackungsmaschinen der genannten Art sind üblicherweise mit zwei Transportketten ausgestattet, die für den Transport einer Materialbahn, wie einer Folie oder dergleichen vorgesehen sind. An der Kette sind hierbei innenseitig, d.h. auf der der Materialbahn zugewandten Seite Halterungselemente, beispielsweise Klemmelemente angebracht, um die zu transportierende Materialbahn, z.B. eine Folie zu ergreifen und mit dem Vorschub der Kette zu transportieren. Verpackungsmaschinen mit solchen Transportketten sind beispielsweise in der Druckschrift DE 33 15 419 A1 oder der EP 14 98 353 A1 beschrieben.Packaging machines of the type mentioned are usually equipped with two transport chains, which are provided for the transport of a material web, such as a film or the like. On the chain here are on the inside, ie on the material web side facing support members, such as clamping elements mounted to take the material to be transported web, such as a foil and to transport with the feed of the chain. Packaging machines with such transport chains are for example in the document DE 33 15 419 A1 or the EP 14 98 353 A1 described.

Da die zu transportierende Materialbahn zwischen den beiden Transportketten aufgespannt transportiert wird, wirken auf die Transportketten Querkräfte quer zur Vorschubrichtung, denen diese Transportketten standhalten müssen. Daher werden derartige Transportketten in Führungselementen geführt, die die notwendige Stabilität in Querrichtung bewirken. Üblich sind hierbei C-Profile aus Metall, in die ein weiteres C-Profil aus Kunststoff mit guten Gleiteigenschaften für die Kette angeordnet ist. Das außen liegende C-Profil aus Metall dient dabei zur Montage sowie zur Versteifung der Kettenführung. Eine solche Kettenführung ist beispielsweise in der Druckschrift DE 43 14 550 A1 beschrieben.Since the material to be transported web is transported spanned between the two transport chains act on the transport chains transverse forces transverse to the feed direction, which must withstand these transport chains. Therefore, such transport chains are guided in guide elements, the bring about the necessary stability in the transverse direction. Common here are C-profiles made of metal, in which a further C-profile made of plastic with good sliding properties for the chain is arranged. The outer C-profile made of metal serves for mounting and stiffening the chain guide. Such a chain guide is for example in the document DE 43 14 550 A1 described.

Auf der der Transportbahn gegenüberliegenden Außenseite der Transportkette bildet sich bei einer derartigen Ausführungsform ein durch die Kette verschlossener Hohlraum. Auch durch die ineinanderliegenden Profile dieser Führungsvorrichtung ergeben sich Hohlräume, Ritzen oder dergleichen.On the transport path opposite the outside of the transport chain is formed in such an embodiment, a closed by the chain cavity. Also by the nested profiles of this guide device cavities, cracks or the like arise.

In den genannten Hohlräumen, Ritzen oder dergleichen können sich Keimherde bilden, was insbesondere beim Einsatz in einer Verpackungsmaschine für Lebensmittel aus hygienischen Gründen von Nachteil ist.In said cavities, cracks or the like, germs may form, which is particularly disadvantageous when used in a packaging machine for food for hygienic reasons.

Aufgabe der Erfindung ist es daher, eine Verpackungsmaschine der genannten Art vorzuschlagen, mit der eine bessere Hygiene zu verwirklichen ist.The object of the invention is therefore to propose a packaging machine of the type mentioned, with which better hygiene is to be realized.

Diese Aufgabe wird ausgehend von einer Maschine gemäß dem Oberbegriff des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved on the basis of a machine according to the preamble of claim 1 by the characterizing features of claim 1.

Durch die in den Unteransprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.The measures mentioned in the dependent claims advantageous embodiments and developments of the invention are possible.

Dementsprechend zeichnet sich eine erfindungsgemäße Verpackungsmaschine dadurch aus, dass die Vorrichtung zur Kettenführung auf der der Transportseite gegenüberliegenden Außenseite der Kette wenigstens bereichsweise so offen gehalten ist, dass die Kettenaußenseite und/oder die sich an der Kette anschließenden Führungselemente wenigstens bereichsweise von der Außenseite her zur Reinigung zugänglich sind.Accordingly, a packaging machine according to the invention is characterized in that the device for chain guide on the opposite side of the transport side of the chain at least partially open is held that the outer chain side and / or the subsequent to the chain guide elements are at least partially accessible from the outside for cleaning.

Hierdurch ist eine bessere Reinigung der Kette sowie der im Bereich der Kette befindlichen Führungselemente möglich, ohne dass die entsprechenden Maschinenkomponente demontiert werden müssen. Zugleich werden durch eine solche Bauweise Hohlräume, Ritzen oder dergleichen vermieden, wo durch entsprechende Verunreinigungen an derartigen Stellen mit der damit verbundenen Beeinträchtigung der Hygiene entfallen.As a result, a better cleaning of the chain and located in the chain guide elements is possible without the corresponding machine component must be dismantled. At the same time cavities, cracks or the like are avoided by such a construction, where accounted for by corresponding impurities in such places with the associated impairment of hygiene.

Vorteilhafterweise wird die Vorrichtung zur Kettenführung an einem Halterungsprofil mit Abstand zu diesem befestigt. Das Halterungsprofil dient dabei zur Versteifung der Vorrichtung zur Kettenführung, wobei durch die beabstandete Befestigung die erfindungsgemäße Zugänglichkeit von der Außenseite her gewährleistet bleibt.Advantageously, the device for chain guide is attached to a support profile at a distance to this. The support profile serves to stiffen the device for chain guide, wherein the inventive accessibility is ensured by the spaced attachment from the outside.

In einer bevorzugten Weiterbildung dieser Ausführungsform werden mehrere in Längsrichtung voneinander beabstandete Befestigungselemente zur Befestigung der Vorrichtung zur Kettenführung vorgesehen, wobei der Zwischenraum zwischen den Befestigungselementen frei zugänglich ist. Durch derartige Befestigungselemente, die zugleich als Abstandshalter zwischen der Vorrichtung zur Kettenführung und dem oben angeführten Halterungsprofil dienen können, wird die Vorrichtung zur Kettenführung quasi freischwebend befestigt. Berührungspunkte bestehen lediglich im Bereich dieser Befestigungselemente. In dem Zwischenbereich ist die Kettenführung von der Außenseite her frei zugänglich, so dass die erfindungsgemäße vorteilhafte Reinigungsmöglichkeit gewährleistet ist.In a preferred embodiment of this embodiment, a plurality of longitudinally spaced fastening elements are provided for fastening the device to the chain guide, wherein the gap between the fastening elements is freely accessible. By such fasteners, which can serve as a spacer between the device for chain guide and the above-mentioned support profile at the same time, the device for chain guide is fixed quasi free floating. Points of contact exist only in the area of these fastening elements. In the intermediate region, the chain guide is freely accessible from the outside, so that the advantageous cleaning possibility according to the invention is ensured.

In einer vorteilhaften Ausführungsform der Erfindung umfasst die Kettenführung eine erste Führungsleiste. Die Ausbildung als Führungsleiste ist konstruktiv einfach und gewährleistet zugleich eine Führung der Kette und Stabilisierung gegenüber Querkräften, die beispielsweise durch die zu transportierende Materialbahn auf die Kette ausgeübt werden können.In an advantageous embodiment of the invention comprises the chain guide a first guide rail. The design as a guide bar is structurally simple and at the same time ensures a leadership of the chain and stabilization against lateral forces that can be exerted on the chain, for example, by the material to be transported web.

Bevorzugt wird eine solche Führungsleiste als Auflageleiste für die Kette ausgebildet, so dass die Kette durch diese Führungsleiste nicht nur in Querrichtung geführt wird, sondern zugleich eine tragende Auflage durch die Führungsleiste erhält.Preferably, such a guide bar is designed as a support strip for the chain, so that the chain is guided by this guide bar not only in the transverse direction, but at the same time receives a bearing support by the guide rail.

Vorteilhafterweise werden die Kettenglieder so ausgebildet, dass sie wenigstens teilweise Kettenlaschen umfassen, die seitlich neben die Führungsleiste überstehen und diese so wenigstens teilweise umgreifen. Hierdurch kann die oben angeführte Führungsfunktion und insbesondere die Überleitung von Querkräfte, die beispielsweise durch die zu transportierende Materialbahn auf die Kette ausgeübt werden, auf die Führungsleiste bewirkt werden.Advantageously, the chain links are formed so that they at least partially comprise link plates, which project laterally next to the guide bar and thus at least partially embrace. As a result, the above-mentioned guiding function and in particular the transfer of transverse forces which are exerted on the chain, for example, by the material web to be transported, are effected on the guide rail.

Bevorzugt wird eine zweite Führungsleiste vorgesehen, wobei die Kette zwischen den beiden Führungsleisten geführt ist. In diesem Fall ist die Kette vollständig zwischen den Führungsleisten fixiert und erhält nur noch einen Freiheitsgrad in der Bewegung in Längsrichtung. Hierdurch kann eine besonders stabile Kettenführung realisiert werden, die auch größeren Querkräften Stand hält und darüber hinaus Vertikalbewegungen der Kette verhindert, so dass eine sichere Positionierung in vertikaler Richtung sichergestellt ist.Preferably, a second guide rail is provided, wherein the chain is guided between the two guide rails. In this case, the chain is completely fixed between the guide rails and receives only one degree of freedom in the movement in the longitudinal direction. In this way, a particularly stable chain guide can be realized, which also withstands larger transverse forces and moreover prevents vertical movements of the chain, so that a secure positioning in the vertical direction is ensured.

In einer Weiterbildung der beschriebenen Ausführungsform werden die eine oder beide Führungsleisten mit Distanzelementen am Halterungsprofil befestigt. Derartige Distanzelemente können beispielsweise Distanzhülsen sein, in die eine Spannschraube zum Verschrauben der Führungsleisten am Halterungsprofil eingeführt werden können. Vorzugsweise werden die Fügestellen dieser Distanzhülse an den Führungsleisten und/oder am Halterungsprofil durch Dichtelemente abgedichtet oder am Halterungsprofil verschweißt, so dass in diesem Bereich keine schmutz- und keimempfindlichen Hohlräume oder Kapillaren entstehen können und so die erfindungsgemäß vorzusehenden Hygieneverhältnisse realisierbar sind.In a further development of the described embodiment, the one or both guide rails are fastened with spacer elements on the support profile. Such spacers may be, for example spacers in which a clamping screw for screwing the guide rails can be introduced on the support profile. Preferably, the joints of this spacer sleeve are sealed to the guide rails and / or on the support profile by sealing elements or welded to the support profile, so that no dirt and germ-sensitive cavities or capillaries can arise in this area and so the invention to be provided hygienic conditions can be realized.

In einer besonderen Ausführungsform der Erfindung werden die Führungsleisten in ein Hüllprofil eingefügt. Ein solches Hüllprofil kann die mechanische Stabilität der Führungsleisten verbessern, wobei für die Gleitflächen der Führungsleiste ein Material vorrangig unter Berücksichtigung der Gleiteigenschaften des Materials in Zusammenwirkung mit der Kette auswählbar ist.In a particular embodiment of the invention, the guide rails are inserted into an enveloping profile. Such an enveloping profile can improve the mechanical stability of the guide rails, wherein a material is primarily selectable taking into account the sliding properties of the material in cooperation with the chain for the sliding surfaces of the guide rail.

Eine Führungsleiste aus einem Material mit guten Gleiteigerischaften kann dabei durch das Hüllprofil, das im Hinblick auf die mechanische Steifigkeit ausgebildet wird, versteift werden.A guide strip made of a material with good slip imperfections can be stiffened by the enveloping profile, which is formed with regard to the mechanical rigidity.

In der letztgenannten Ausführungsform wird vorteilhafterweise das Hüllprofil mit Abstandshaltern befestigt, so dass sich eine insgesamt mechanisch sehr stabile Anordnung ergibt, wobei das Hüllprofil mit den eingefügten Führungsleisten erfindungsgemäß von der Außenseite zur Reinigung zugänglich ist.In the latter embodiment, the envelope profile is advantageously fastened with spacers, so that an overall mechanically very stable arrangement results, wherein the envelope profile with the inserted guide strips according to the invention is accessible from the outside for cleaning.

Das Hüllprofil kann dabei so ausgebildet sein, dass es lediglich eine Führungsleiste umhüllt, so dass im Falle von zwei Führungsleisten zwei Hüllprofile verwendet werden, die jeweils eine Führungsleiste stabilisieren.The enveloping profile can be designed so that it envelops only one guide strip, so that in the case of two guide rails two enveloping profiles are used, each stabilizing a guide strip.

Es ist jedoch auch denkbar, ein Hüllprofil zu verwenden, das C-profilartig geformt ist und somit sowohl eine obere als auch eine untere Führungsleiste umhüllen kann. In dieser Ausführungsform wird vorteilhafterweise das Hüllprofil mit Ausnehmungen versehen, durch die erfindungsgemäß die Führungskette und/oder die Führungsleisten wenigstens im Bereich der Kette zur Reinigung zugänglich sind.However, it is also conceivable to use an enveloping profile, which is C-shaped like a profile and thus both an upper than can also wrap a lower guide strip. In this embodiment, the enveloping profile is advantageously provided with recesses, by means of which according to the invention the guide chain and / or the guide strips are accessible for cleaning at least in the region of the chain.

Die Führungsleisten können beispielsweise aus einem gleitfähigen Kunststoff, beispielsweise einem Polyethylen gefertigt sein. Denkbar wären jedoch auch andere Materialien, beispielsweise ein nicht abrasives harzgetränktes Hartgewebe (HGW), ein keramisches oder metallisches Material, wie Edelstahl oder dergleichen, insbesondere ein gleitschichtbeschichtetes Metall, wie beschichteter Edelstahl usw..The guide rails can be made for example of a lubricious plastic, such as a polyethylene. However, other materials would also be conceivable, for example a non-abrasive resin-impregnated hard tissue (HGW), a ceramic or metallic material, such as stainless steel or the like, in particular a sliding-layer-coated metal, such as coated stainless steel, etc.

In einer besonderen Ausführungsform der Erfindung werden die Führungsleisten mit Stabilisierungselementen versehen. Insbesondere bei der Verwendung einer Kunststoffleiste können Stabilisierungselemente die mechanische Steifigkeit der Führungsleiste erhöhen. Diese Stabilisierungselemente können beispielsweise durch Fasermaterial gebildet sein, beispielsweise von Glasfasern oder auch Kohlefasern, das zusammen mit dem Kunststoff homogen verteilt in die Führungsleisten eingebracht wird, wobei die Oberfläche gegebenenfalls mit einer Beschichtung versehen wird, um abrasive Eigenschaften zu vermeiden.In a particular embodiment of the invention, the guide rails are provided with stabilizing elements. In particular, when using a plastic strip stabilizing elements can increase the mechanical rigidity of the guide rail. These stabilizing elements can be formed for example by fiber material, for example of glass fibers or carbon fibers, which is homogeneously distributed together with the plastic in the guide rails, wherein the surface is optionally provided with a coating to avoid abrasive properties.

Eine andere Ausführungsform könnte aus einem mechanisch stabilen Kern, beispielsweise aus Glasfaser oder Metall mit einem entsprechenden Gleitmantel, beispielsweise aus Kunststoff bestehen. Auch eine solche Ausführungsform würde sowohl die Gleiteigenschaften eines dafür geeigneten Materials mit der mechanischen Steifigkeit eines anderen, mechanisch steiferen Materials vereinen. Derartige Führungen können z.B. koextrudiert werden.Another embodiment could consist of a mechanically stable core, for example of glass fiber or metal with a corresponding sliding jacket, for example made of plastic. Such an embodiment would combine both the sliding properties of a suitable material with the mechanical stiffness of another, mechanically stiffer material. Such guides may e.g. be coextruded.

Auch eine Verbundleiste, die laminatartig aus einer Leiste mit guten Gleiteigenschaften für die Führungskette und einer Leiste zur mechanischen Versteifung gebildet wird, wäre erfindungsgemäß denkbar. Ein solches Laminat könnte auch aus mehr als zwei Lagen bestehen und so die gewünschten Eigenschaften erzielen.Also a composite strip, the laminate of a bar formed with good sliding properties for the guide chain and a bar for mechanical stiffening, the invention would be conceivable. Such a laminate could also consist of more than two layers and thus achieve the desired properties.

Eine weitere vorteilhafte Ausführungsform der Erfindung ist durch eine Profilierung der Führungsleisten möglich. So kann eine Führungsleiste beispielsweise als T-, L- und/oder H-Profil ausgebildet werden, um die mechanische Stabilität gegenüber Querkräften zu verbessern. Eine solche strukturierte Profilgebung kann beispielsweise kombiniert werden mit der Verwendung verschiedener Materialien und/oder eines Laminats wie oben angeführt.A further advantageous embodiment of the invention is possible by profiling the guide rails. For example, a guide strip can be designed as a T, L and / or H profile in order to improve the mechanical stability with respect to transverse forces.

Die Vorrichtung 1 zur Kettenführung gemäß Figur 1 kann in verschiedenen Verpackungsmaschinen zum Einsatz kommen, beispielsweise in Maschinen gemäß dem einleitend genannten Stand der Technik, insbesondere Rollen- oder Tiefziehmaschinen oder Schalenversiegelungsmaschinen.The device 1 for chain guide according to FIG. 1 can be used in various packaging machines, for example in machines according to the introductory state of the art, in particular roller or thermoforming machines or tray sealing machines.

Eine Transportkette 2 ist umlaufend entlang der Transportstrecke geführt, so dass sich ein Obertrumm 3 sowie ein Untertrumm 4 ergibt. An einigen Kettengliedern, beispielsweise den dargestellten Kettengliedern 5 und 6 sind Klemmvorrichtungen 7, 8 zum Einklemmen einer Materialbahn, beispielsweise einer Verpackungsfolie zwischen Klemmbacken 9, 10 angebracht. Somit kann mit dem Vorschub der Transportkette 2 eine zu transportierende Materialbahn mitgeführt werden. Bei Verpackungsmaschinen der genannten Art wird eine solche Verpackungsfolie während des Transports im Obertrumm 3 mitgeführt und z.B. bei der Umlenkung ins Untertrumm 4 durch entsprechende Auslösemechanismen aus den Klemmvorrichtungen 7, 8 gelöst.A transport chain 2 is guided circumferentially along the transport path, so that an upper strand 3 and a lower strand 4 results. At some chain links, for example, the chain links 5 and 6 shown clamping devices 7, 8 for clamping a web, such as a packaging film between jaws 9, 10 are attached. Thus, with the feed of the transport chain 2, a material web to be transported can be carried. In packaging machines of the type mentioned, such a packaging film is carried during transport in the upper strand 3 and is e.g. in the deflection in Untertrumm 4 solved by appropriate release mechanisms from the clamping devices 7, 8.

Die Transportkette 2 umfasst Kettenglieder 5, 6 mit Kettenlaschen 11, 12, die eine erste untere 13 sowie eine zweite obere 14 Führungsleiste seitlich umgreifen. Hierdurch ist die Transportkette 2 gegenüber Querkräften in Richtung des Pfeils Q, die beispielsweise durch die in den Klemmvorrichtungen 7 gehaltene Materialbahn verursacht werden, stabil in den Führungsleisten 13, 14 gehalten.The transport chain 2 comprises chain links 5, 6 with link plates 11, 12, which laterally surround a first lower 13 and a second upper 14 guide strip. As a result, the transport chain 2 with respect to transverse forces in the direction of the arrow Q, which are caused for example by the material held in the clamping devices 7 web, stably held in the guide rails 13, 14.

Die Führungsleisten 13, 14 des Obertrumms bzw. 15, 16 des Untertrumms 4 sind über Abstandshalter 17 an einem Halterungsprofil 18 befestigt, beispielsweise verschraubt. In der Darstellung gemäß Figur 1 sind zwei verschiedene Varianten von Führungsleisten 13, 14 bzw. 15, 16 dargestellt. Das Halterungsprofil 18 stabilisiert über die Abstandshalter 17 zudem die Führungsleisten 13, 14, 15, 16. Die dem Untertrumm 4 zugeordneten Führungsleisten 15, 16 sind einstückig, während die zur Darstellung eines weiteren Ausführungsbeispiels dem Obertrumm 3 zugeordneten Führungsleisten 13, 14 zweiteilig aus einem Stabilisierungskern 19 und einem Gleitmantel 20 bestehen. Die Variante gemäß der Darstellung des Obertrumms 3 soll veranschaulichen, dass die Führungsleisten 13, 14 aus unterschiedlichen Materialien zusammengesetzt sein können, um einerseits mechanische Stabilität, beispielsweise durch den Stabilisierungskern 19 bei guten Gleiteigenschaften, beispielsweise durch den Gleitmantel 20 zu kombinieren.The guide rails 13, 14 of the upper strand or 15, 16 of the lower strand 4 are fixed by spacers 17 on a support profile 18, for example screwed. In 1, two different variants of guide rails 13, 14 and 15, 16 are shown. The support section 18 also stabilizes the guide rails 13, 14, 15, 16 via the spacers 17. The guide rails 15, 16 assigned to the lower run 4 are in one piece, while the guide runners 13, 14 assigned to the upper run 3 represent a two-part stabilizing core 19 and a sliding jacket 20 exist. The variant according to the illustration of the upper strand 3 is intended to illustrate that the guide strips 13, 14 may be composed of different materials, on the one hand to combine mechanical stability, for example by the stabilizing core 19 with good sliding properties, for example by the sliding shell 20.

Die Variante gemäß dem Untertrumm 4 hingegen ist ohne Stabilisierungskern ausgebildet, da die oben angeführten Querkräfte durch eingespanntes Material 29 nur im Obertrumm 3 auftreten.The variant according to the Untertrumm 4, however, is formed without stabilizing core, since the above-mentioned lateral forces occur by clamped material 29 only in the upper strand 3.

Im Übrigen wäre eine mechanisch stabile Ausgestaltung ohne Stabilisierungskern auch mit einem Material realisierbar, das beide Eigenschaften gleichermaßen verwirklicht, beispielsweise einem Kunstoff-Glasfaser-Verbundwerkstoff, der eine homogene Materialdurchmischung zeigt oder einen Verbundwerkstoff aus einem Glasfaserkern mit Kunststoffmantel.Incidentally, a mechanically stable configuration without a stabilizing core would also be possible with a material that embodies both properties equally, for example a plastic-glass fiber composite material that exhibits homogeneous material mixing or a composite material made of a glass fiber core with a plastic jacket.

In Figur 2 ist in der perspektivische Darstellung ersichtlich, dass die Abstandshalter 17, 17', in Längsrichtung L mit großen Abständen zueinander angeordnet sind. Hierdurch sind die Führungsleisten 13, 14 sowie die darin gelagerte Kette von der der zu transportierenden Materialbahn gegenüberliegenden Außenseite 21 her einer Reinigung zugänglich. In Figur 2 sind zur verbesserten Anschaulichkeit lediglich drei Kettenglieder mit drei Klemmvorrichtungen im Obertrumm 3 dargestellt. Grundsätzlich muss nicht jedes Kettenglied mit einer Klemmvorrichtung 7 versehen sein. Die Anzahl und Anordnung ist nach den jeweiligen Anforderungen der Maschine auszuwählen.In FIG. 2 it can be seen in the perspective view that the spacers 17, 17 'are arranged in the longitudinal direction L at great distances from each other. As a result, the guide rails 13, 14 as well as the chain mounted therein are accessible for cleaning from the outer side 21 of the material web to be transported. In Figure 2 are improved Illustrated only three links with three clamping devices in the upper strand 3 shown. Basically, not every chain link has to be provided with a clamping device 7. The number and arrangement must be selected according to the requirements of the machine.

Wie anhand von Figur 2 ersichtlich ist, ist eine durchgehende Führung des Untertrumms 4 nicht zwingend erforderlich. Je nach Anwendungsfall kann auf eine solche Führung ganz verzichtet oder eine lückenbehaftete Führung entsprechend Figur 2 vorgesehen werden.As can be seen with reference to FIG. 2, a continuous guidance of the lower run 4 is not absolutely necessary. Depending on the application, it is possible to dispense with such a guide altogether or to provide a gap-type guide according to FIG. 2.

Die Figuren 3 und 4 zeigen eine weitere Variante der Erfindung, bei der Führungsleisten 22, 23 für eine Transportkette 24 in einem C-Profil 25 eingebettet sind, das als Hüllprofil für die Führungsleisten 22, 23 dient. In der Schnittdarstellung ergibt sich somit ein Bild, wie es aus dem Stand der Technik bekannt ist. Abweichend vom Stand der Technik ist jedoch nunmehr das Hüllprofil 25 in Höhe der Kette mit Ausnehmungen 26 versehen, so dass auch bei dieser Ausführungsform die Transportkette 24 sowie die Führungsleisten 22, 23 von der Außenseite 27 her zur Reinigung zugänglich sind. Um diese Zugänglichkeit zu ermöglichen, wird das Hüllprofil 25 ebenfalls über Distanzelemente (nicht näher dargestellt), die beispielsweise als Distanzhülsen über die Befestigungsschrauben 28 gesteckt werden können, an einem entsprechenden Maschinenteil, beispielsweise einem Halterungsprofil entsprechend dem Halterungsprofil 18 gemäß Figur 1, befestigt. Somit ergibt sich ein Abstand zwischen der dem Hüllprofil 25 und dem zugehörigen Maschinenteil, beispielsweise einem Halterungsprofil 18, über den die erfindungsgemäße Zugänglichkeit verwirklicht wird.Figures 3 and 4 show a further variant of the invention, are embedded in the guide rails 22, 23 for a transport chain 24 in a C-profile 25, which serves as an envelope for the guide rails 22, 23. The sectional view thus results in an image, as is known from the prior art. Deviating from the prior art, however, now the envelope profile 25 is provided at the level of the chain with recesses 26, so that in this embodiment, the conveyor chain 24 and the guide rails 22, 23 are accessible from the outside 27 for cleaning. In order to enable this accessibility, the enveloping profile 25 is also fastened via spacer elements (not shown in greater detail), which can be inserted, for example, as spacers via the fastening screws 28, to a corresponding machine part, for example a mounting profile corresponding to the mounting profile 18 according to FIG. This results in a distance between the envelope profile 25 and the associated machine part, for example a support profile 18, via which the accessibility according to the invention is realized.

Die Figuren 5 und 6 zeigen eine weitere Ausführungsform für die Gestaltung der Zugänglichkeit der Kette von der Außenseite her.Figures 5 and 6 show a further embodiment for the design of the accessibility of the chain of the Outside.

Dabei ist ein Winkelprofil 30 mit hakenförmigen Halterungselementen 31, 32 versehen. Die Halterungselemente 31, 32 können beispielsweise aus dem Winkelprofil 30 durch Stanzen und Rollen gefertigt werden. Zwischen diesen Halterungselementen 31, 32 ist ein Abstand vorgesehen, der der Breite einer Führungsleiste 33 entspricht, so dass diese in die hakenförmigen Halterungselemente 31, 32 eingeführt werden kann. Die Führungsleiste 33 ist hierbei mit einer Abstufung 34 versehen, die sich an dem übergreifenden Halterungselement 31 stirnseitig abstützt.In this case, an angle section 30 with hook-shaped support members 31, 32 is provided. The support members 31, 32 can be made for example from the angle section 30 by punching and rolling. Between these support members 31, 32, a distance is provided which corresponds to the width of a guide rail 33, so that it can be inserted into the hook-shaped support members 31, 32. The guide rail 33 is in this case provided with a gradation 34, which is supported on the overarching support member 31 frontally.

Für die gegenüberliegende Führungsleiste 35 sind entsprechende Halterungselemente in das Winkelprofil 30 eingeformt, wobei in der Darstellung gemäß Figur 5 nur das von unten die Führungsleiste 35 umgreifende Halterungselement 36 sichtbar ist.For the opposite guide rail 35 corresponding support members are formed in the angle section 30, wherein in the illustration of Figure 5, only the bottom of the guide rail 35 embracing support member 36 is visible.

Die Ausführung gemäß den Figuren 5 und 6 ist besonders fertigungs- und montagefreundlich, da die Halterungselemente einfach zu fertigen sind und die Führungsleisten 33, 35 lediglich in die Halterungselemente 31, 32 bzw. 36 eingesetzt werden müssen. Nach dem Einführen der nicht dargestellten Kette werden die Führungsleisten 33, 35 durch die Kette auf Abstand gehalten und somit in den Halterungselementen 31, 32, 36 fixiert.The embodiment according to Figures 5 and 6 is particularly easy to manufacture and easy to install, since the support members are easy to manufacture and the guide rails 33, 35 only in the support members 31, 32 and 36 must be used. After insertion of the chain, not shown, the guide rails 33, 35 held by the chain at a distance and thus fixed in the support members 31, 32, 36.

Diese Funktion ist in Figur 6 erkennbar, in der die Kette 38 dargestellt ist.This function can be seen in Figure 6, in which the chain 38 is shown.

Neben den genannten Ausführungsbeispielen sind noch viele weitere, teilweise in den Unteransprüchen weitergebildete Varianten denkbar. Wesentlich ist bei allen Ausführungsvarianten die wenigstens bereichsweise zugängliche Ausbildung und Anordnung der Kette und der zugehörigen Führungselemente.In addition to the aforementioned embodiments, many more, partially further developed in the dependent claims variants are conceivable. It is essential in all embodiments, the at least partially accessible design and arrangement of the chain and the associated Guide elements.
