Abstract

The invention relates to a packaging machine including a machine frame in addition to a method for the construction and alteration thereof. The packaging machine includes a frame made of transversal ( 3, 22, 28, 29 ) and longitudinal elements ( 2, 12, 13, 15, 16, 18, 19, 25, 33 ) for receiving and fixing the individual work stations of the packaging machine, whereby the stations are used, for example, for forming, filling, sealing and labelling the packaging. Displacably mounted securing means for the work stations are fixably arranged on the longitudinal elements of the frames. The invention also relates to a method for constructing the type of packaging machine, whereby the frame is made of longitudinal elements ( 2, 12, 13, 15, 16, 18, 19, 25, 33 ) which preferably are the same length as the individual work stations, and transversal elements ( 3, 22, 28, 29 ) are assembled together and the work stations are consequently suspended, orientated and fixed in the frame. The invention further relates to a method for altering the packaging machine, whereby the respective work stations are removed form the frame once the securing means have been detached. Subsequently, a replacement-work station can be fixed to the longitudinal elements. The longitudinal elements can also be removed, the remaining frame parts being joined together. The old work station is replaced by a new one which has different dimensions, and the longitudinal elements are also replaced by longitudinal elements having a different length.

Description

Die Erfindung betrifft eine Verpackungsmaschine mit einem Rahmen zur Aufnahme und Fixierung von Arbeitsstationen, beispielsweise zum Formen, Siegeln, Schneiden und Etikettieren von Verpackungen. Insbesondere betrifft die Erfindung eine Maschine zur Herstellung von tiefgezogenen Verpackungsmulden aus einer Kunststofffolie. Darüber hinaus betrifft die Erfindung Verfahren zur Errichtung und zum Umbau einer solchen Verpackungsmaschine.The invention relates to a packaging machine with a frame for receiving and fixing workstations, for example, for molding, sealing, cutting and labeling of packaging. In particular, the invention relates to a machine for producing thermoformed packaging trays made of a plastic film. Moreover, the invention relates to methods for the construction and conversion of such a packaging machine.

Maschinen der in Rede stehenden Art (s. z.B. US 3 938 302-A) bestehen aus einer Vielzahl von Arbeitsstationen, die unterschiedliche Funktionen erfüllen und üblicherweise hintereinander aufgestellt und ausgerichtet werden. Nach dem Abwickeln durchläuft eine Kunststofffolie dabei beispielsweise nach einer eventuellen Aufheizung die Bereiche Formen, Abkühlen, Befüllen, Siegeln, Etikettieren und Schneiden. Dabei muss aber vor allem sichergestellt sein, dass die relative Lage der einzelnen Arbeitsstationen sowohl zueinander als auch zu den über die gesamte Länge der Maschine wirkenden Arbeitsmitteln, so etwa der Transportvorrichtung für die Folienbahn oder -bahnen, dauerhaft gewährleistet ist.Machines of the type in question (see, for example, US 3 938 302-A) consist of a plurality of workstations which perform different functions and are usually set up and aligned one behind the other. After unwinding, a plastic film passes through the areas of shaping, cooling, filling, sealing, labeling and cutting, for example after a possible heating up. But above all, it must be ensured that the relative position of the individual workstations is permanently guaranteed both to one another and to the working means acting over the entire length of the machine, such as the transport device for the film web or webs.

Die Arbeitsstationen müssen daher so angeordnet werden, dass eine Ausrichtung der einzelnen Komponenten aufeinander dauerhaft gesichert ist. Eine Möglichkeit dieser Sicherung ist beispielsweise die Verwendung eines die jeweilige Arbeitsstation umfassenden Maschinenrahmens. Bei den bekannten Verpackungsmaschinen mit Rahmen werden vorgefertigte Einheiten, bestehend aus einem Rahmen und der eigentlichen Arbeitsstation, aneinandergereiht, ausgerichtet und gegebenenfalls miteinander verbunden. Der Austausch einzelner Arbeitsstationen ist bei den Verpackungsmaschinen gemäß dem Stand der Technik nur schwierig durchzuführen. Auch ein nachträglicher Einbau neuer Arbeitsstationen mit andern Abmessungen ist in die bekannten Verpackungsmaschinen in den meisten Fällen nur mit einem erheblichen Aufwand möglich.The workstations must therefore be arranged so that an alignment of the individual components is permanently secured to each other. One way this backup is, for example, the use of a respective workstation comprehensive machine frame. In the known packaging machines with frame prefabricated units consisting of a frame and the actual workstation, strung together, aligned and possibly interconnected. The replacement of individual workstations is difficult to perform in the packaging machines according to the prior art. Also, a subsequent installation of new workstations with other dimensions is possible in the known packaging machines in most cases only with considerable effort.

Es war daher eine Aufgabe der Erfindung eine Verpackungsmaschine zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist und die einfach herzustellen und umzubauen ist.It was therefore an object of the invention to provide a packaging machine which does not have the disadvantages of the prior art and which is easy to manufacture and modify.

Die Aufgabe der Erfindung wird durch eine Verpackungsmaschine mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung finden sich in den abhängigen Ansprüchen.The object of the invention is achieved by a packaging machine with the features of claim 1. Preferred embodiments of the invention can be found in the dependent claims.

Gemäß der Erfindung ist somit eine Verpackungsmaschine zur Verfügung gestellt worden, die in einfacher Bauweise zusammengestellt und bei Bedarf auch um einzelne oder mehrere Arbeitsstationen erweitert oder vermindert werden kann. Der Maschinenrahmen wird dabei in einer auf die Abmessungen der Maschine abgestimmten Weise errichtet, um die einzelnen Arbeitsstationen der Maschine aufzunehmen. Im wesentlichen besteht der Maschinenrahmen aus Querelementen, welche mit einer Mehrzahl von Längselementen, auf denen die Arbeitsstationen zumindest teilweise verschiebbar gelagert und daran fixierbar angebracht sind,According to the invention, a packaging machine has thus been provided which can be assembled in a simple construction and, if necessary, can be extended or reduced by individual or multiple workstations. The machine frame is erected in a manner adapted to the dimensions of the machine to accommodate the individual workstations of the machine. In essence, the machine frame consists of transverse elements, which are mounted with a plurality of longitudinal elements on which the workstations are at least partially displaceably mounted and fixed thereto,

Die Längselemente können dabei jeden beliebigen, vorzugsweise über die Länge konstanten Querschnitt aufweisen, um ein Verschieben der Fixierungsmittel in Längsrichtung zu ermöglichen. Dies kann beispielsweise bei Verwendung von Längselementen mit rechteckigem oder quadratischem Querschnitt oder auch bei profilierten Blechen gegeben sein. Besonders vorteilhaft ist jedoch die Verwendung von Rohren, vorzugsweise mit im wesentlichen runder Querschnittsfläche. Hierdurch wird insbesondere die Möglichkeit eröffnet, Rohre auf besonders einfache Weise miteinander zu verbinden und eine hohe Steifigkeit des Maschinenrahmens zu erzielen. Weiterhin bevorzugt sind Profile, vorzugsweise Rohre mit einem rechteckigen oder quadratischen Querschnitt. Bei der Verwendung dieser Profile wird das Verschieben der Fixierungsmittel deutlich vereinfacht. Des weiteren wird durch die Verwendung runder Rohre die Reinigung der Maschine, die besonders bei einer Verwendung als Verpackungsmaschine für Lebensmittel häufig und gründlich durchgeführt wird, erleichtert, da die Reinigungsmittel hier in der Regel abtropfen können und sich keine Ansammlungen auf Oberflächen bilden.The longitudinal elements can have any desired, preferably over the length constant cross-section to allow a displacement of the fixing means in the longitudinal direction. This can be done, for example, when using longitudinal elements with rectangular or square cross-section or in profiled sheets. However, the use of tubes, preferably with a substantially round cross-sectional area, is particularly advantageous. As a result, in particular the possibility is opened to connect pipes in a particularly simple manner with each other and to achieve a high rigidity of the machine frame. Further preferred are profiles, preferably tubes with a rectangular or square cross-section. When using these profiles, the shifting of the fixing means is greatly simplified. Furthermore, the use of round pipes facilitates the cleaning of the machine, which is frequently and thoroughly carried out especially when used as a packaging machine for foodstuffs, since the cleaning agents can generally drip off here and accumulate on surfaces.

Die Länge der Längselemente richtet sich nach den jeweiligen Gegebenheiten. Die Längselemente können sich jeweils über die gesamte Länge der Verpackungsmaschine erstrecken oder aber auch kürzer sein. Die Längselemente können einstückig ausgeführt sein oder sich jeweils aus mehreren Teilstücken zusammensetzen.The length of the longitudinal elements depends on the particular circumstances. The longitudinal elements can each extend over the entire length of the packaging machine or else be shorter. The longitudinal elements can be made in one piece or each composed of several sections.

Falls sich die Längselemente aus mehreren Teilstücken zusammensetzen, erfolgt deren Verbindung vorzugsweise so, daß eine hohe Steifigkeit des Maschinenrahmens gewährleistet ist. Eine solche Verbindung ist in einer vorteilhaften Ausgestaltung der Erfindung gegeben, wenn mit den Enden der Längselemente senkrechte Laschen verbunden sind. Durch Aneinandersetzen und reversibles Verbinden der Laschen wird eine besonders einfache und sichere form- und kraftschlüssige Verbindung der Längselemente hergestellt, die zudem leicht gelöst werden kann. In einer besonders bevorzugten Ausgestaltung der Erfindung erfolgt diese Verbindung der Laschen durch Schrauben. Durch diese besonders vorteilhafte Ausgestaltung wird eine besonders leicht zu lösende und auf die jeweiligen Gegebenheiten anpassungsfähige und sichere Verbindung der Längselemente geschaffen.If the longitudinal elements composed of several sections, their connection is preferably such that a high rigidity of the machine frame is ensured. Such a connection is given in an advantageous embodiment of the invention, when connected to the ends of the longitudinal elements vertical tabs. By juxtaposing and reversibly connecting the tabs a particularly simple and secure positive and non-positive connection of the longitudinal elements is produced, which can also be easily solved. In a particularly preferred embodiment of the invention, this connection of the tabs is done by screws. This particularly advantageous embodiment provides a particularly easy to solve and adaptable to the particular circumstances and secure connection of the longitudinal elements.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung erfolgt die Verbindung der Längselemente über ein zwei gegenläufige Gewinde aufweisendes Verbindungselement, vorzugsweise ein Mehrkant-Verbindungselement. Bei der Verbindung der Längselemente mit dem Verbindungselement wird eine feste Verbindung erzielt. Des weiteren können die verbundenen Längselemente auch vorgespannt werden. Eine hohe Steifigkeit des Maschinenrahmens ist in dieser bevorzugten Ausgestaltung der Erfindung ebenfalls gewährleistet.In a further advantageous embodiment of the invention, the connection of the longitudinal elements via a two opposing thread exhibiting connecting element, preferably a polygonal connecting element. In the connection of the longitudinal elements with the connecting element, a firm connection is achieved. Furthermore, the connected longitudinal elements can also be biased. A high rigidity of the machine frame is also ensured in this preferred embodiment of the invention.

Weitere bevorzugte Ausführungsformen der Verbindung der Längselemente sind in den Figuren 9a, b sowie 10a, b dargestellt.Further preferred embodiments of the connection of the longitudinal elements are shown in FIGS. 9a, b and 10a, b.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung weisen Paare von vertikal beabstandeten Längselementen Verbindungsstege auf. Durch diese Stege kann die Steifigkeit der Rahmenkonstruktion deutlich erhöht werden. Dabei ist es besonders vorteilhaft, die Stege derart anzubringen, dass ein Verschieben der Fixierungsmittel und/oder Arbeitsstationen entlang der Längselemente nicht behinaert wird, zumindest aber weiterhin möglich ist. In einer weiteren besonders vorteilhaften Ausgestaltung der Erfindung können diese Stege an die Längselemente angeschweißt werden. Dies stellt zum einen eine einfach herzustellende Form der Verbindung zwischen den Längselementen dar. Zum anderen besteht die Möglichkeit, die Stege auch nachträglich an der bereits bestehende Rahmenkonstruktion anzubringen, um etwa die Steifigkeit der gesamten Konstruktion zu erhöhen oder aber auch nur gezielt Teilbereiche des Rahmens zu verstärken.In a further advantageous embodiment of the invention, pairs of vertically spaced longitudinal elements on connecting webs. Through these webs, the rigidity of the frame construction can be significantly increased. It is particularly advantageous to attach the webs such that a displacement of the fixing means and / or workstations along the longitudinal elements is not behinert, but at least it is still possible. In a further particularly advantageous embodiment of the invention, these webs can be welded to the longitudinal elements. On the one hand, it is also possible to subsequently attach the webs to the already existing frame construction in order to increase, for example, the rigidity of the entire construction or else only selectively subregions of the frame strengthen.

Die Fixierungsmittel können in jeder beliebigen Form und Anzahl an der erfindungsgemäßen Verpackungsmaschine angebracht sein. Um eine sichere Verbindung zwischen dem Maschinenrahmen und den einzelnen Arbeitsstationen der Verpackungsmaschine zu gewährleisten ist es von Vorteil, wenn die Fixierungsmittel die Längselemente zumindest teilweise formschlüssig umgreifen. Die Fixierungsmittel können einstückig ausgebildet sein und bereits vor dem Zusammenbau des Maschinenrahmens auf die Längselemente aufgeschoben werden. Besonders vorteilhaft ist eine Ausgestaltung der Fixierungsmittel aus mehreren Teilen, die miteinander verbunden den zumindest teilweisen Formschluss mit den Längselementen bewirken. Hierdurch wird ein nachträgliches Anbringen weiterer Fixierungsmittel oder ein Abnehmen überschüssiger Fixierungsmittel auch ohne einen zumindest teilweisen Abbau des Maschinenrahmens möglich.The fixing means may be mounted in any desired form and number on the packaging machine according to the invention. In order to ensure a secure connection between the machine frame and the individual workstations of the packaging machine, it is advantageous if the fixing means engage around the longitudinal elements at least partially positively. The fixing means may be formed in one piece and be pushed onto the longitudinal elements prior to assembly of the machine frame. Particularly advantageous is an embodiment of the fixing means of a plurality of parts, which connected to each other cause the at least partial positive connection with the longitudinal elements. As a result, subsequent attachment of further fixing means or removal of excess fixing means is possible even without at least partial dismantling of the machine frame.

In einer besonders vorteilhaften Ausgestaltung der Erfindung bestehen die Fixierungsmittel aus zwei im wesentlichen gleichartigen miteinander verbundenen Hälften, die im Zusammenspiel die Längselemente von zwei Seiten zumindest teilweise formschlüssig umschließen.In a particularly advantageous embodiment of the invention, the fixing means of two substantially similar interconnected halves, which enclose the longitudinal elements of two sides at least partially form-fitting in interaction.

Prinzipiell ist die Lagerung der Fixierungsmittel an jeweils einem Längselement ausreichend. Bei Verwendung von runden Rohren als Längselemente ist es aber zur sicheren und drehfesten Lagerung der Fixierungsmittel notwendig, dass diese jeweils mit mindestens zwei vertikal beabstandeten Längselementen, vorzugsweise runden Rohren zusammenwirken. Durch diese Ausgestaltungsform der erfindungsgemäßen Verpackungsmaschine ist eine sichere Fixierung der Arbeitsstationen an den Längselementen am Rahmen gewährleistet.In principle, the storage of the fixing agent on each one longitudinal element is sufficient. When using round tubes as longitudinal elements, however, it is necessary for secure and non-rotatable mounting of the fixing means that they interact in each case with at least two vertically spaced longitudinal elements, preferably round tubes. This embodiment of the packaging machine according to the invention ensures secure fixing of the work stations to the longitudinal elements on the frame.

Zur sicheren Fixierung der jeweiligen Arbeitsstationen am Rahmen sind jeweils mindestens zwei Fixierungsmittel vorzusehen, die mit zwei an der Arbeitsstation diagonal gegenüberliegenden Angriffpunkten verbunden sind. Vorzugsweise jedoch erfolgt die Fixierung der jeweiligen Arbeitsstationen über mindestens drei vorzugsweise vier Fixierungsmittel, wobei wenigstens ein Fixierungsmittel auf jeder Längsseite der jeweiligen Arbeitsstation wirken muss.For secure fixation of the respective workstations on the frame at least two fixing means are provided, which are connected to two diagonally opposite points of attack at the workstation. Preferably, however, the fixation of the respective workstations via at least three preferably four fixing means, wherein at least one fixing agent must act on each longitudinal side of the respective workstation.

Weiterhn bevorzugt sind Fixierungsmittel beliebiger Art direkt an den Arbeitsstationen vorgesehen. Diese Arbeitsstationen können innerhalb des Maschinenrahmens verschoben und dann an der gewünschten Stelle fixiert werden. Die Fixierung erfolgt vorzugsweise durch Reibschluß mit den Längselementen.Weiterhn preferred fixative of any kind are provided directly to the workstations. These workstations can be moved within the machine frame and then fixed at the desired location. The fixation is preferably carried out by frictional engagement with the longitudinal elements.

Ein Querelement im Sinne der Erfindung ist jedes Bauelement, das geeignet ist, quer zur Längsachse der Längselemente als Abstandhalter zwischen den Längselementen zu dienen und eine ausreichende Steifigkeit der Rahmenkonstruktion zu gewährleisten. Der Fachmann erkennt, dass die Querelemente nicht notwendigerweise aus einem Vollmaterial gefertigt sein müssen. Es ist ebenfalls denkbar, Rahmen, gegebenenfalls durch Quer- oder Diagonalelemente verstärkt, Gitter oder auch durchbrochen Bleche wie etwa Lochbleche oder dergleichen vorzusehen. Der Fachmann erkennt auch, dass die Querelemente ebenso aus mehreren Teilen, beispielsweise Pfosten und Querstreben einer beliebigen Form zusammengesetzt sein können.A transverse element in the context of the invention is any component which is suitable to serve as a spacer between the longitudinal elements transversely to the longitudinal axis of the longitudinal elements and to ensure sufficient rigidity of the frame structure. The person skilled in the art recognizes that the transverse elements do not necessarily have to be made of a solid material. It is also conceivable frame, possibly reinforced by transverse or diagonal elements, grid or perforated plates such as perforated plates or the like provided. The skilled person also recognizes that the transverse elements can also be composed of several parts, such as posts and cross members of any shape.

Zwei Querelemente bilden die Stirnwände einer erfindungsgemäßen Verpackungsmaschine. Weitere Querelemente werden darüber hinaus bei Bedarf innerhalb des Rahmens eingesetzt. Durch den Einbau weiterer Querelemente in den Rahmen wird die Konstruktion deutlich verstärkt. Der Einbau von versteifenden Elementen kann dabei ohne besonderen Aufwand auch nachträglich erfolgen, sofern sich beispielsweise Schwächen der Konstruktion in einzelnen Bereichen zeigen sollten. Er kann aber ebenso notwendig sein Querelemente temporär einzuziehen, beispielsweise, wenn die Belastung der Rahmenkonstruktion erhöht wird, so etwa beim Transport des gesamten Rahmens zusammen mit den in ihm fixierten Arbeitsstationen. Die Querelemente können auch beispielsweise bei einem Umbau der Maschine entlang der Längselemente verschoben werden und dann wieder fixiert werden.Two transverse elements form the end walls of a packaging machine according to the invention. Additional cross members are also used within the frame as needed. By installing additional cross members in the frame, the construction is significantly strengthened. The incorporation of stiffening elements can also be done subsequently without any special effort, provided, for example, weaknesses of the design in individual areas should show. But it may also be necessary to temporarily feed transverse elements, for example, when the load on the frame structure is increased, such as the transport of the entire frame together with the fixed in him workstations. The cross elements can also, for example, during a conversion be moved along the longitudinal elements of the machine and then fixed again.

In einer vorteilhaften Ausgestaltung der Erfindung sind in den Seiten der Querelemente Aussparungen vorgesehen, die geeignet sind, zumindest einen Teilumfang der Längselemente aufzunehmen. Durch eine solche Ausgestaltung der erfindungsgemäßen Verpackungsmaschine wird eine platzsparende Bauweise des Maschinenrahmens auf besonders einfache Weise verwirklicht.In an advantageous embodiment of the invention recesses are provided in the sides of the transverse elements, which are adapted to receive at least a partial circumference of the longitudinal elements. By such an embodiment of the packaging machine according to the invention a space-saving design of the machine frame is realized in a particularly simple manner.

Vorzugsweise weist die erfindungsgemäße Verpackungsmaschine zumindest in Teilbereichen Versteifungen auf. Diese Versteifungen sind vorzugsweise weitere Längselemente, die sich über mindestens zwei Querelemente erstrecken. Durch diese Ausgestaltung des Rahmens wird die Steifigkeit der Konstruktion entweder gezielt in Teilbereichen oder aber im gesamten Rahmen besonders wirksam erhöht.The packaging machine according to the invention preferably has stiffeners at least in some areas. These stiffeners are preferably further longitudinal elements which extend over at least two transverse elements. As a result of this embodiment of the frame, the rigidity of the construction is increased particularly effectively, either specifically in partial areas or else in the entire frame.

In einer vorteilhaften Ausgestaltung der Erfindung sind an den einzelnen Arbeitsstationen Mittel zur verschiebbaren Lagerung der Arbeitsstationen vorgesehen, über die eine Lageveränderung der Arbeitsstation, vorzugsweise entlang der Längselemente möglich ist. Hierdurch wird ein Verschieben, insbesondere eine Justierung der Arbeitsstationen auf eine besonders einfache und schnell durchzuführende Weise ermöglicht.In an advantageous embodiment of the invention, means for the displaceable mounting of the workstations are provided at the individual workstations, via which a change in position of the workstation, preferably along the longitudinal elements is possible. In this way, a displacement, in particular an adjustment of the workstations in a particularly simple and quickly carried out manner allows.

In einer besonders vorteilhaften Ausgestaltung der Erfindung sind diese Mittel mit den Arbeitsstaionen verbunden. In einer überaus bevorzugten Ausgestaltung der Erfindung erfolgt die Verschiebung der Arbeitsstationen in dem Maschinenrahmen mit einer Zahnstange oder Spindel. Durch diese besonders bevorzugte Ausgestaltung der Erfindung wird eine besonders sichere und stufenlos einstellbare Möglichkeit der Justierung eröffnet, die zudem ein hohes Maß an Genauigkeit bietet.In a particularly advantageous embodiment of the invention, these means are connected to the working stations. In a most preferred embodiment of the invention, the displacement of the workstations in the machine frame with a rack or spindle. This particularly preferred embodiment of the invention, a particularly safe and infinitely adjustable possibility of adjustment is opened, which also offers a high degree of accuracy.

Es kann darüber hinaus sinnvoll sein, nur einen Teil der innerhalb des Maschinenrahmens befindlichen Arbeitsstationen zu fixieren. Dies ist immer dann von Vorteil, wenn eine exakte Ausrichtung mit den anderen Arbeitsstationen nicht notwendig erscheint. Auch kann durch eine solche Ausgestaltung eine Übertragung von Vibrationen von einer Arbeitsstation auf die andere oder aber auf den gesamten Rahmen wirksam unterbunden werden.It may also be useful to fix only some of the workstations within the machine frame. This is always an advantage if an exact alignment with the other workstations does not seem necessary. Also, by such a configuration, a transmission be effectively prevented from vibrations from one workstation to the other or on the entire frame.

An dem Maschinenrahmen der erfindungsgemäßen Maschine werden vorzugsweise zusätzlich Mittel zur Befestigung von Abdeckplatten oder ―blenden vorgesehen sein. Das Abdecken einzelner Maschinenbereiche erfolgt regelmäßig im Rahmen der für den Betrieb einer solchen Verpackungsmaschine geltenden Sicherheitsvorschriften. Durch die Abdeckungen kann beispielsweise der Kontakt der Maschinenkomponenten mit dem Bedienpersonal vermieden werden, so dass eine Kontamination der Verpackungsfolien unterbunden und die Verletzungsgefahr minimiert wird.On the machine frame of the machine according to the invention, means for fastening cover plates or panels are preferably additionally provided. The covering of individual machine areas is carried out regularly within the framework of the safety regulations applicable to the operation of such a packaging machine. Through the covers, for example, the contact of the machine components can be avoided with the operator, so that a contamination of the packaging films prevented and the risk of injury is minimized.

Der Rahmen der erfindungsgemäßen Verpackungsmaschine ist vorzugsweise aus einem Material hergestellt, das sowohl die für die Erfüllung der oben genannten Aufgaben notwendige Festigkeit und Tragkraft besitzt als auch gegen aggressive Medien wie Reinigungs- oder Desinfektionsmittel beständig ist. Gerade bei der Verwendung von Maschinen zur Herstellung von Verpackungen für Lebensmittel ist aufgrund der hohen einzuhaltenden Hygienestandards eine gründliche und aufwendige Reinigung und Desinfektion der gesamten Anlage regelmäßig und in kurzen Intervallen notwendig. Es ist daher sinnvoll, den Rahmen aus einem Werkstoff herzustellen, der in der Lage ist, beide Aufgaben zu erfüllen, wie beispielsweise Aluminium oder rostfreier Stahl. Es ist aber auch denkbar, beide Aufgaben von verschiedenen Komponenten einer Werkstoffkombination, etwa eines beschichteten Materials, erfüllen zu lassen.The scope of the packaging machine according to the invention is preferably made of a material which has both the strength and carrying capacity necessary for the fulfillment of the abovementioned objects and is also resistant to aggressive media such as cleaning agents or disinfectants. Especially when using machines for the production of packaging for food is due to the high standards of hygiene to be complied with a thorough and costly cleaning and disinfection of the entire system regularly and at short intervals necessary. It is therefore useful to make the frame from a material capable of performing both tasks, such as aluminum or stainless steel. But it is also conceivable to fulfill both tasks of different components of a material combination, such as a coated material.

Die Form des Maschinenrahmens sollte aber aufgrund der Häufigkeit der Reinigung in jedem Fall unter dem Gesichtspunkt gestaltet werden, dass keine schwer zugänglichen Bereiche, insbesondere aber keine Rückhaltebereiche, in denen sich Restmengen des Reinigungsmittels ohne Abflussmöglichkeit ansammeln können, vorhanden sind.However, due to the frequency of cleaning, the shape of the machine frame should in any case be designed in such a way that there are no hard-to-reach areas, but in particular no retention areas, in which residual quantities of the cleaning agent can accumulate without outflow possibility.

Die Erfindung betrifft darüber hinaus ein Verfahren zur Errichtung und zum Umbau von der erfindungsgemäßen Verpackungsmaschine, welches im folgenden näher erläutert wird. Die aufgeführten Verfahrensschritte sind jedoch weder als abschließende Aufzählung aller Arbeitsschritte zu verstehen noch gibt die beanspruchte Auflistung eine Reihenfolge vor, in der diese Schritte bei Durchführung des erfindungsgemäßen Verfahrens ausgeführt werden müssen.The invention also relates to a method for the construction and conversion of the packaging machine according to the invention, which will be explained in more detail below. However, the listed process steps are neither as to understand concluding enumeration of all steps still gives the claimed listing an order in which these steps must be performed when carrying out the method according to the invention.

Das erfindungsgemäße Verfahren zur Errichtung einer Verpackungsmaschine sieht vor, dass der Auf- und Zusammenbau des Maschinenrahmens durch Verbinden der Längselemente mit den Querelementen erfolgt. In diesen Maschinenrahmen werden dann die einzelnen Arbeitsstationen eingehängt, anschließend werden die jeweiligen Arbeitsstationen durch Verschieben ausgerichtet und schließlich mit dem Maschinenrahmen kraftschlüssig verbunden.The inventive method for constructing a packaging machine provides that the assembly and assembly of the machine frame is carried out by connecting the longitudinal elements with the transverse elements. In this machine frame then the individual workstations are mounted, then the respective workstations are aligned by moving and finally non-positively connected to the machine frame.

Bei Durchführung des erfindungsgemäßen Verfahrens wird in einfacher Weise ein auf die jeweiligen Erfordernisse der zu errichtenden Maschine abgestimmter Rahmen mit besonders einfachen Mitteln hergestellt. Darüber hinaus wird die Möglichkeit eröffnet, den Aufbau schnell und mit einfachen Mitteln vor Ort durchzuführen.When carrying out the method according to the invention, a frame adapted to the respective requirements of the machine to be erected is produced in a simple manner with particularly simple means. In addition, the possibility is opened up to carry out the construction quickly and with simple means on site.

Bei einem weiteren erfindungsgemäßen Verfahren wir die Verpackungsmaschine beispielsweise bei Defekt einzelner Anlagenteile umgebaut, indem die Arbeitsstationen nach Lösen der Fixierungsmittel aus dem bestehenden Rahmen herausgenommen werden. Eine Austausch-Station kann dann in den Rahmen eingesetzt und kraftschlüssig mit dem Rahmen verbunden werden. Durch eine derartige Ausgestaltung des erfindungsgemäßen Verfahrens können auf besonders einfache Weise und bei besonders geringem Zeitaufwand Anlagenteile ausgetauscht werden, wobei die Austausch-Station nicht dieselben Längenmaße wie die ursprüngliche Station aufweisen muß.In a further method according to the invention we rebuilt the packaging machine, for example, in case of failure of individual parts of the system by the workstations are removed after loosening the fixing means of the existing frame. An exchange station can then be inserted into the frame and frictionally connected to the frame. By such an embodiment of the method according to the invention system parts can be replaced in a particularly simple manner and at a very low cost, the exchange station does not have to have the same length dimensions as the original station.

Anlagenteile mit anderen Ausmaßen als die ausgetauschten können in den Rahmen eingefügt werden, indem vor oder nach dem Einsetzen der neuen Arbeitsstation ein Verschieben der übrigen Arbeitsstationen entlang der Längselemente erfolgt. Gleichfalls kann, beispielsweise bei Wegfall von ausgeführten Arbeitsschritten, eine Arbeitsstation ersatzlos entnommen werden. Die Maschine wird dann in besonders einfacher Weise durch Verschieben der restlichen Arbeitsstationen in dem bestehenden Maschinenrahmen wieder in den optimalen Betriebszustand gebracht.Plant parts of dimensions other than those exchanged may be inserted into the frame by shifting the remaining work stations along the longitudinal members before or after the new workstation is inserted. Likewise, a workstation can be removed without replacement, for example in the absence of executed steps. The machine is then brought in a particularly simple manner by moving the remaining workstations in the existing machine frame back to the optimal operating condition.

Figur 1 zeigt die erfindungsgemäße Verpackungsmaschine in schematischer Darstellung. Eine Folie 42 wird von einer Rolle abgerollt und durchläuft zunächst eine Tiefziehstation 43, die aus einem Oberwerkzeug 44 und einem Unterwerkzeug 45 besteht. Das Unterwerkzeug 45 ist auf einer Platte 46 montiert, die, wie durch den Pfeil angedeutet, angehoben und abgesenkt werden kann. In der Tiefziehstation 43 wird die Folie 42 zu einer Verpackungsmulde 47 verformt. Figure 1 shows the packaging machine according to the invention in a schematic representation. A film 42 is unrolled from a roll and first passes through a thermoforming station 43, which consists of an upper tool 44 and a lower tool 45. The lower tool 45 is mounted on a plate 46 which can be raised and lowered as indicated by the arrow. In the thermoforming station 43, the film 42 is deformed into a packaging tray 47.

Danach werden die Verpackungsmulden 47 mit einem Verpackungsgut befüllt und in der folgenden Siegelstation 48 werden die Verpackungsmulden mit einer Deckelfolie versiegelt. Auch die Siegelstation 48 besteht aus einem Oberwerkzeug 49 und einem Unterwerkzeug 50, wobei auch bei der Siegelstation das Unterwerkzeug 50 angehoben und abgesenkt werden kann.Thereafter, the packaging trays 47 are filled with a packaged product and in the following sealing station 48, the packaging trays are sealed with a lidding film. Also, the sealing station 48 consists of an upper tool 49 and a lower tool 50, wherein also in the sealing station, the lower tool 50 can be raised and lowered.

Abschließend werden die Verpackungen in der Schneidstation 51 auseinandergeschnitten. Auch die Schneidstation besteht aus einem Oberwerkzeug 52 und einem Unterwerkzeug 53, wobei auch bei der Schneidstation das Unterwerkzeug 53 angehoben und abgesenkt werden kann.Finally, the packages are cut apart in the cutting station 51. Also, the cutting station consists of an upper tool 52 and a lower tool 53, wherein also at the cutting station, the lower tool 53 can be raised and lowered.

In Figur 2 wird ein Maschinenrahmen 1 dargestellt, welcher aus rohrförmigen Längselementen 2 und Querelementen 3 besteht. Des weiteren sind Fixierungselemente 4, bestehend aus einer außenliegenden Hälfte 5 und einer innenliegenden Hälfte 6, dargestellt, die auf den Längselementen 2 verschiebbar und fixierbar angebracht sind. Ebenfalls sind Mittel 26 zur Fixierung der Querelemente 3 an den Längselementen 2 angebracht. Die Querelemente 3 weisen an ihren Unterseiten 11 Aussparungen 7 zur Aufnahme eines Teilumfangs der Längselemente 2 auf. In den Seitenwänden der Querelemente 3 sind ebenfalls Aussparungen 27 gleicher Form vorgesehen. Die Aussparungen 7 sind so gestaltet, dass sie zusammen mit den Mitteln 26 zur Fixierung der Querelemente 3 die Längselemente 2 formschlüssig umgreifen. Die Außenhälften 5 der Fixierungsmittel 4, 14 und die Mittel 26 zur Fixierung der Querelemente 3 können zudem gleich gestaltet werden. In diesem Fall haben die Aussparungen 7, 27 an den Querelementen 3 eine Form, bei der beim Zusammenfügen der Querelemente und der Mittel 26 Form- und/oder Kraftschluss zwischen dem Querelement 3 und dem Längselement 2 erzielt wird. FIG. 2 shows a machine frame 1 which consists of tubular longitudinal elements 2 and transverse elements 3. Furthermore, fixing elements 4, consisting of an outer half 5 and an inner half 6, are shown, which are mounted on the longitudinal elements 2 displaceable and fixable. Also, means 26 for fixing the transverse elements 3 are attached to the longitudinal elements 2. The transverse elements 3 have on their undersides 11 recesses 7 for receiving a partial circumference of the longitudinal elements 2. In the side walls of the cross members 3 are also Recesses 27 provided the same shape. The recesses 7 are designed so that they engage around the longitudinal elements 2 in a form-fitting manner together with the means 26 for fixing the transverse elements 3. The outer halves 5 of the fixing means 4, 14 and the means 26 for fixing the transverse elements 3 can also be made the same. In this case, the recesses 7, 27 on the transverse elements 3 have a shape in which, when joining the transverse elements and the means 26, positive and / or frictional connection is achieved between the transverse element 3 and the longitudinal element 2.

Der gesamte Maschinenrahmen 1 ruht auf einer Vielzahl von verstellbaren Füßen 9, mit denen ein Niveauausgleich, beispielsweise bei Bodenunebenheiten, möglich ist.The entire machine frame 1 rests on a variety of adjustable feet 9, with which a leveling, for example in uneven floors, is possible.

Zum Einhängen der Arbeitsstationen in den Maschinenrahmen 1 ist es notwendig, dass wenigstens zwei horizontal beabstandete und parallel verlaufende Längselemente 2 die benachbarten Querelemente 3 miteinander verbinden. Darüber hinaus kann eine Erhöhung der Steifigkeit der Konstruktion durch Hinzufügen einer beliebigen Anzahl weiterer Längselemente 2 zu den bereits vorhandenen Längselementen erreicht werden. Im Mittenbereich 10 des Maschinenrahmens 1 sind dazu beispielsweise an der Unterseite 11 der Seitenwände der Wandelemente 3 zwei Längselemente 12, 13 angebracht.To mount the work stations in the machine frame 1, it is necessary that at least two horizontally spaced and parallel longitudinal elements 2 connect the adjacent cross members 3 together. In addition, an increase in the rigidity of the construction can be achieved by adding any number of further longitudinal elements 2 to the already existing longitudinal elements. In the middle region 10 of the machine frame 1, for example, two longitudinal elements 12, 13 are attached to the underside 11 of the side walls of the wall elements 3.

Figur 3 zeigt ebenfalls einen Maschinenrahmen 1, in welchem zwei übereinander angebrachte und parallel verlaufende Längselemente 15, 16 über eine Vielzahl von Stegen 17 miteinander verbunden sind. Diese Stege 17 sind in der Darstellung gleichmäßig über die Länge des Maschinenrahmens 1 verteilt. Es ist jedoch ebenfalls denkbar, dass die Stege 17 in bestimmten Bereichen einen kürzeren Abstand zueinander aufweisen, möglicherweise auch in anderen Bereichen des Maschinenrahmens 1 gänzlich fehlen. FIG. 3 likewise shows a machine frame 1, in which two longitudinal elements 15, 16, which are mounted one above the other and run parallel, are connected to one another via a multiplicity of webs 17. These webs 17 are distributed uniformly over the length of the machine frame 1 in the illustration. However, it is also conceivable that the webs 17 in certain areas have a shorter distance from each other, possibly also completely absent in other areas of the machine frame 1.

In Figur 4 ist ein Maschinenrahmen 1 in einer weiteren Ausführungsform dargestellt. Die Längselemente 25 dieser Ausführungsform bestehen aus Profilblechen 18 und schienenförmigen Elementen 19, die auf Blöcken 20, welche durch ein Trennstück 21 voneinander beabstandet sind, auf den Querelementen 22 ruhen. Die Aussparungen 23 der Querelemente 22 weisen die Form der Profilbleche 18 auf. Die Profilbleche 18 sind mit Anschlagmitteln 24 an den Querelementen 22 befestigt. Hier nicht gezeigte Mittel zur Fixierung der nicht gezeigten Maschinenkomponenten sind verschiebbar zwischen den verschiedenen Anschlagmitteln 24 gelagert. Bei der in Fig. 3 dargestellten Ausführungsform der Längselemente 25 und bei jeder andersartigen Ausführungsform, bei der die Längselemente 25 keinen runden Querschnitt aufweisen, ist es zur sicheren Fixierung der Arbeitsstationen ausreichend, wenn die Fixierungsmittel (hier nicht gezeigt) lediglich mit einem Längselement 25 zusammenwirken und auf diesem verschiebbar und fixierbar gelagert sind. FIG. 4 shows a machine frame 1 in a further embodiment. The longitudinal elements 25 of this embodiment consist of profile sheets 18 and rail-shaped elements 19 which rest on blocks 20, which are spaced apart by a separator 21, on the cross members 22. The recesses 23 of the transverse elements 22 have the shape of the profiled sheets 18. The Profile sheets 18 are fastened with stop means 24 to the cross members 22. Means not shown here for fixing the machine components, not shown, are displaceably mounted between the various stop means 24. In the embodiment of the longitudinal elements 25 shown in FIG. 3 and in any other embodiment in which the longitudinal elements 25 do not have a round cross-section, it is sufficient for secure fixing of the workstations if the fixing means (not shown here) cooperate only with a longitudinal element 25 and are mounted on this displaceable and fixable.

In Figur 5 wird ein Maschinenrahmen 1 dargestellt, bei dem die Querelemente 3 aus senkrechten Querpfosten 28, Querrohren 29 und unteren und oberen Verbindungsmitteln 30, 31 zur kraftschlüssigen Verbindung der Querpfosten 28 und Querrohre 29 bestehen. Die Mittel 28 und 29 sind Querelemente im Sinne der Erfindung. Die oben liegenden Paare von Längselementen 15, 16 weisen an ihren Enden die Längselemente 15 und 16 miteinander verbindende senkrechte Laschen 32 auf. Die Verbindung mehrerer Paare von Längselementen 15, 16 erfolgt dann durch eine form- und kraftschlüssige Verbindung der Laschen 32 eines jeden Paares von Längselementen 15, 16. Die unterhalb der Paare von Längselementen 15, 16 liegenden Längselemente 33 werden ebenfalls über senkrecht zu den Längselementen 33 stehenden Laschen 34 miteinander verbunden. In den Querpfosten 28 sind Aufnahmen für die Querrohre 29 vorgesehen. Darüber hinaus weisen die Verbindungsmittel 30, 31 Aufnahmen für die Querpfosten 28 und die Querrohre 29 auf. Des weiteren weisen die Verbindungsmittel 30, 31 Öffnungen auf, durch die die Längselemente 15, 16, 33 hindurchgeführt werden können. Mit den oberen Verbindungsmitteln 31 sind zudem Haltemittel 35 verbunden, an denen weitere Mittel (nicht gezeigt) zur Versteifung der Querelemente 3 befestigt werden können. FIG. 5 shows a machine frame 1 in which the transverse elements 3 consist of vertical transverse posts 28, transverse tubes 29 and lower and upper connecting means 30, 31 for the non-positive connection of the transverse posts 28 and transverse tubes 29. The means 28 and 29 are transverse elements in the context of the invention. The overhead pairs of longitudinal elements 15, 16 have at their ends the longitudinal elements 15 and 16 interconnecting vertical tabs 32. The connection of several pairs of longitudinal elements 15, 16 then takes place by a positive and non-positive connection of the tabs 32 of each pair of longitudinal elements 15, 16. The below the pairs of longitudinal elements 15, 16 longitudinal elements 33 are also perpendicular to the longitudinal elements 33rd standing tabs 34 connected to each other. In the transverse posts 28 receptacles for the transverse tubes 29 are provided. In addition, the connecting means 30, 31 have receptacles for the transverse posts 28 and the transverse tubes 29. Furthermore, the connecting means 30, 31 openings, through which the longitudinal elements 15, 16, 33 can be passed. Holding means 35 are additionally connected to the upper connecting means 31, to which means (not shown) for reinforcing the transverse elements 3 can be fastened.

Figur 6 ist eine vergrößerte Detailzeichnung der Ausführungsform gemäß Figur 4 dargestellt. Die Laschen 32, 34 weisen Bohrungen 36 zum Aufnehmen von Nieten oder Schrauben zur kraftschlüssigen Verbindung der mit den Längselementen 15, 16, 33 verbundenen Laschen 32, 34 auf. Die unteren Verbindungsmittel 30 sind aus einem äußeren Teil 37 und einem inneren Teil 38 zusammengesetzt. Der innere Teil 38 des unteren Verbindungsmittels 30 weist eine Aufnahme für ein Querrohr 29 sowie eine Aussparung auf, in der ein Teilumfang des Längselements 33 aufgenommen wird. Mit dem inneren Teil 38 ist der Querpfosten 28 formschlüssig verbunden. Der äußere Teil 37 der unteren Verbindungsmittel 30 weist ebenfalls eine Aufnahme für einen Teilumfang des Längselements 33 auf.

Mit dem inneren Teil 40 sind zudem in Längsrichtung des Maschinenrahmens 1 verlaufende Haltemittel 41 in Form von zwei parallelen voneinander beabstandeten Klemmschienen zum Aufnehmen von weiteren versteifenden Elementen (nicht gezeigt) der Querelemente 3 verbunden. FIG. 6 is an enlarged detailed drawing of the embodiment according to FIG. 4. The tabs 32, 34 have holes 36 for receiving rivets or screws for non-positive connection of the longitudinal elements 15, 16, 33 connected tabs 32, 34. The lower connecting means 30 are composed of an outer part 37 and an inner part 38. The inner part 38 of the lower connecting means 30 has a receptacle for a cross tube 29 and a recess in which a partial circumference of the longitudinal member 33 is received. With the inner part 38 of the transverse post 28 is positively connected. The outer part 37 of the lower connecting means 30 also has a receptacle for a partial circumference of the longitudinal element 33. In combination, the parts 37 and 38 form a positive connection with the longitudinal element 33. The upper connecting means 31 are composed of an outer part 39 and an inner part 40. The outer part 39 has two recesses for receiving a partial circumference of the longitudinal elements 15 and 16. The inner part 40 also has these recesses, so that the parts 39, 40 composed the longitudinal elements 15, 16 engage around a form fit. Holding means 41 running in the longitudinal direction of the machine frame 1 are also connected to the inner part 40 in the form of two parallel spaced-apart clamping rails for receiving further stiffening elements (not shown) of the transverse elements 3.

Figur 7 zeigt einen von der Spiegelachse versetzten Schnitt durch das Querelement 3 gemäß der Figuren 4 und 5. Mit den inneren Teilen 38 der unteren Verbindungsmittel 30 sind Füße 9 verbunden, auf denen der gesamte Maschinenrahmen ruht. Mit den inneren Teilen 40 der oberen Verbindungsmittel 31 sind Haltemittel 35 verbunden, in die Nuten 41 zum Einschieben und/oder Verklemmen von weiteren versteifenden Elementen eingebracht sind. Figure 7 shows a section offset from the mirror axis by the transverse element 3 according to Figures 4 and 5. To the inner parts 38 of the lower connecting means 30 are connected feet 9 on which the entire machine frame rests. With the inner parts 40 of the upper connecting means 31 holding means 35 are connected, are introduced into the grooves 41 for insertion and / or jamming of further stiffening elements.

Figur 8a zeigt eine perspektivische Ansicht eines weiteren Querelementes. In dem vorliegenden Fall sind die Querpfosten 28 als U-Profile ausgeführt, in die die inneren Teile 38, 40 der Verbindungsmittel eingearbeitet sind. Die Längselemente 2 werden von diesen Verbindungsmitteln teilweise aufgenommen. Die äußeren Verbindungsmittel 37, 39 werden an die Querpfosten angeschraubt und umschließen die Längselemente 2 ebenfalls teilweise. Die beiden Querpfosten 28 sind durch ein an den Kanten aufgebogenes Blech 61 miteinander verbunden. FIG. 8a shows a perspective view of another transverse element. In the present case, the transverse posts 28 are designed as U-profiles, in which the inner parts 38, 40 of the connecting means are incorporated. The longitudinal elements 2 are partially received by these connecting means. The outer connecting means 37, 39 are screwed to the transverse posts and also partially surround the longitudinal elements 2. The two transverse posts 28 are connected to each other by a sheet 61 bent up at the edges.

Figur 8b zeigt eine Seitenansicht des Querelementes gemäß Figur 8a. Diese Ansicht verdeutlicht insbesondere, dass alle Teile so miteinander verbunden bzw. so konstruiert sind, dass Spalte 63 vorhanden sind, durch die Reinigungswasser abfließen kann. Diese Konstruktion ist sehr hygienisch, weil Flüssigkeitsansammlungen vermieden werden. Der Abstand zwischen dem Blech 61 und dem Querpfosten 28 wird beispielsweise durch eine Unterlegscheibe 62 Realisiert. FIG. 8b shows a side view of the transverse element according to FIG. 8a. This view illustrates in particular that all parts are connected or constructed so that there are gaps 63 through which cleaning water can flow. This construction is very hygienic because Liquid accumulations are avoided. The distance between the sheet 61 and the transverse post 28 is realized, for example, by a washer 62.

Figur 9a, b zeigt eine Ausführungsform der Verbindung zwischen zwei Längselementen 2, die im wesentlichen aus zwei L-förmig gestalteten Teilen 2ünd 2" gestaltet ist. Die Teile 2'und 2"sind jeweils mit einem Längselement verschweißt. Diese beiden werden mittels des Gewindes 65 und nicht dargestellten Schrauben miteinander verbunden und durch die Stifte 64 gegeneinander zentriert. 9a, b shows an embodiment of the connection between two longitudinal elements 2, which is essentially made up of two L-shaped parts 2 and 2 "The parts 2 'and 2" are each welded to a longitudinal element. These two are connected to each other by means of the thread 65 and screws, not shown, and centered by the pins 64 against each other.

Figur 10a, b zeigt eine weitere Ausführungsform der Verbindung zwischen zwei Längselementen 2, die im wesentlichen als Zapfen 2" der in eine Bohrung 2'eingeführt wird, gestaltet sind. Der kraftschlüssige Verbund erfolgt durch die Stifte 64, die nach dem Einführen des Zapfens in die Bohrung in entsprechende Bohrungen eingeführt werden. 10a, b shows a further embodiment of the connection between two longitudinal elements 2, which are designed essentially as a pin 2 "which is inserted into a bore 2. The non-positive connection is made by the pins 64, which after insertion of the pin in the bore are inserted into corresponding holes.

Figur 11 zeigt die Lagerung einer Arbeitsstation an dem Maschinenrahmen. Jede Arbeitsstation hat mindestens 2, vorzugsweise 4 Räder 66, die zwischen den Längselementen 2 laufen, so dass die Arbeitsstationen entlang des Maschinenrahmens verschoben werden können. In der gewünschten Position werden die Arbeitsstationen mit dem Maschinenrahmen verklemmt. Figure 11 shows the mounting of a work station on the machine frame. Each workstation has at least 2, preferably 4, wheels 66 running between the longitudinal members 2 so that the workstations can be slid along the machine frame. In the desired position, the workstations are clamped to the machine frame.
