Förderrichtung bewegt. Hierzu werden die Artikel von in Förderrichtung hintereinanderliegenden und sich quer zur Förderrichtung erstreckenden Aufnahmeabschnitten an der Außenseite des bewegbaren Körpers aufgenommen. Während des Transportes sind die Aufnahmeabschnitte über im bewegbaren Körper ausgebildete Durchlässe mit einer Unterdruckquelle verbunden, sodass die zu fördernden Artikel durch einen in den Aufnahmeabschnitten ausgebildeten Unterdruck in Richtung auf die Außenseite des bewegbaren Körpers der Fördervorrichtung angesaugt und von diesem während dessen Bewegung mitgenommen werden, wobei die Aufnahmeabschnitte insbesondere nuten- oder muldenförmig ausgebildet sind.In the conveying device of the type mentioned, the transport of the articles of the tobacco processing industry takes place by means of the movable body provided as a conveying element, which moves with its article receiving outside in the direction of movement and thus in the transport or conveying direction. For this purpose, the articles are received on the outside of the movable body one behind the other in the conveying direction and extending transversely to the conveying direction receiving portions. During transport, the receiving portions are connected to a negative pressure source via passages formed in the movable body, so that the articles to be conveyed are sucked by a negative pressure formed in the receiving portions toward the outside of the movable body of the conveyer and are carried along thereby the receiving portions are in particular groove-shaped or trough-shaped.
Bevorzugt wird als Fördervorrichtung der zuvor erwähnten Art eine Rotationsfördervorrichtung verwendet, bei welcher der bewegbare Körper als drehbar gelagerte, angetriebene Trommel ausgebildet ist, um die Artikel der Tabak verarbeitenden Industrie quer zu ihrer Längserstreckung in Rotationsrichtung zu fördern, die somit die Förderrichtung definiert. Derartige Fördervorrichtungen und insbesondere Rotationsfördervorrichtungen werden in Trommelmaschinen der Tabak verarbeitenden Industrie eingesetzt, und zwar insbesondere in Filteransetzmaschinen und Multifilterherstellmaschinen.Preferably, as the conveying device of the aforementioned type, a rotary conveying device is used, in which the movable body is designed as a rotatably mounted, driven drum in order to convey the articles of the tobacco processing industry transversely to its longitudinal extension in the direction of rotation, thus defining the conveying direction. Such conveying devices and in particular rotary conveying devices are used in drum machines of the tobacco processing industry, in particular in filter attachment machines and Multifilterherstellmaschinen.

Aus der
Für die Herstellung von Artikeln der Tabak verarbeitenden Industrie mit unterschiedlichem Format, insbesondere unterschiedlicher Länge, sind die entsprechenden, formatrelevanten Komponenten einer hierfür verwendeten Maschine, insbesondere der Fördervorrichtungen der eingangs genannten Art, an ein geändertes Format anzupassen.For the production of articles of the tobacco processing industry with different format, in particular different length, the corresponding formatrelevanten components of a machine used for this purpose, in particular the conveying devices of the type mentioned, are adapted to a modified format.
Es ist eine Aufgabe der vorliegenden Erfindung, Maßnahmen vorzuschlagen, wodurch sich im Falle eines Formatwechsels die damit verbundene Anpassung der Fördervorrichtung einfach und zuverlässig bewerkstelligen lässt.It is an object of the present invention to propose measures whereby, in the case of a format change, the associated adaptation of the conveying device can be accomplished simply and reliably.
Gelöst wird diese Aufgabe mit einer Aufnahmevorrichtung zur Aufnahme von Artikeln der Tabak verarbeitenden Industrie für eine zum Fördern dieser Artikel ausgebildete Fördervorrichtung, welche einen in Förderrichtung bewegbaren Körper aufweist, an dessen Außenseite, bevorzugt in einer standardisierten Anordnung, mindestens eine erste Saugöffnung und mindestens eine, bevorzugt von der ersten Saugöffnung quer zur Förderrichtung beabstandete, zweite Saugöffnung ausgebildet sind, mit mindestens einem Aufnahmeelement, das eine Außenseite zur Aufnahme mindestens eines Artikels, an der mindestens ein erster Einlass und mindestens ein, bevorzugt vom ersten Einlass quer zur Förderrichtung beabstandeter, zweiter Einlass ausgebildet sind, eine Innenseite, an der mindestens ein erster Auslass und mindestens ein, bevorzugt vom ersten Auslass quer zur Förderrichtung beabstandeter, zweiter Auslass ausgebildet sind, und mindestens einen ersten Verbindungskanal zur Verbindung des ersten Einlasses mit dem ersten Auslass und mindestens einen zweiten Verbindungskanal zur Verbindung des zweiten Einlasses mit dem zweiten Auslass aufweist, und mindestens einer Lage, die am bewegbaren Körper anzuordnen ist und eine Außenseite, eine Innenseite, mit der die Lage an der Außenseite des bewegbaren Körpers der Fördervorrichtung anzuordnen ist, und Durchgangsöffnungen aufweist, die zur Herstellung einer Fluidverbindung zwischen mindestens einem Auslass in dem mindestens einen Aufnahmeelement und mindestens einer Saugöffnung im bewegbaren Körper der Fördervorrichtung vorgesehen sind, dadurch gekennzeichnet, dass das mindestens eine Aufnahmeelement, mit seiner Innenseite der Außenseite der mindestens einen Lage gegenüber liegend, am bewegbaren Körper gegenüber diesem stationär anzuordnen ist und die mindestens eine Lage gegenüber dem mindestens einen Aufnahmeelement zwischen mindestens einer ersten Arbeitsposition und einer von der ersten Arbeitsposition unterschiedlichen zweiten Arbeitsposition verstellbar ist.This object is achieved with a receiving device for receiving articles of the tobacco processing industry for a conveyor device for conveying this article having a movable body in the conveying direction, on the outside, preferably in a standardized arrangement, at least one first suction port and at least one, Preferably, from the first suction opening transversely to the conveying direction spaced, second suction opening are formed, with at least one receiving element having an outer side for receiving at least one article at the at least one first inlet and at least one, preferably from the first inlet transversely to the conveying direction spaced second inlet are formed, an inner side, are formed at the at least one first outlet and at least one, preferably spaced from the first outlet transversely to the conveying direction, second outlet, and at least one first connecting channel for connecting the first egg and at least one second connection channel for connecting the second inlet to the second outlet, and at least one layer, which is to be arranged on the movable body and an outer side, an inner side, with which the position on the outside of the movable body of the To arrange conveying device, and having through openings, which are provided for establishing a fluid connection between at least one outlet in the at least one receiving element and at least one suction opening in the movable body of the conveying device, characterized in that the at least one receiving element, with its inside of the outside of at least a position opposite lying on the movable body relative to this stationary to arrange and the at least one position relative to the at least one receiving element between at least a first working position and a different from the first working position n second working position is adjustable.
Hiernach erfolgt erfindungsgemäß die Steuerung der Saugluft mithilfe mindestens einer Lage, die Durchgangsöffnungen enthält, die zur Herstellung einer Fluidverbindung zwischen mindestens einem Auslass in dem mindestens einen Aufnahmeelement und mindestens einer Saugöffnung im bewegbaren Körper der Fördervorrichtung vorgesehen sind. Dabei wird erfindungsgemäß die Lage zwischen der Außenseite des bewegbaren Körpers der Fördervorrichtung und der Innenseite des mindestens einen Aufnahmeelementes angeordnet. Somit wird der bewegliche Teil der Fördervorrichtung mithilfe der Erfindung zweigeteilt, nämlich in einen bewegbaren Körper und mindestens eine auf den bewegbaren Körper anzuordnen Lage, über der wiederum mindestens ein Aufnahmeelement zur Aufnahme mindestens eines Artikels angeordnet ist.Thereafter, according to the invention, the control of the suction air using at least one layer containing through holes, which is used to produce a Fluid connection between at least one outlet in the at least one receiving element and at least one suction opening in the movable body of the conveying device are provided. In this case, the position between the outside of the movable body of the conveyor and the inside of the at least one receiving element is arranged according to the invention. Thus, the movable part of the conveying device is divided into two parts by means of the invention, namely in a movable body and at least one position to be arranged on the movable body, on which in turn at least one receiving element for receiving at least one article is arranged.
Die Saugöffnungen an der Außenseite des bewegbaren Körpers bilden zweckmäßigerweise ein standardisiertes oder regelmäßiges Lochprofil. Demgegenüber sind die Durchgangsöffnungen in der mindestens einen Lage so auszubilden und zueinander anzuordnen, dass sich im Falle einer Änderung des Formates, insbesondere der Länge, des aufzunehmenden Artikels eine entsprechende Anpassung des Saugluftmusters an der Außenseite des mindestens einen Aufnahmeelementes und somit des Saugverhaltens der Fördervorrichtung durch Veränderung der Position der Lage gegenüber dem bewegbaren Körper erzielen lässt. Die Steuerung der Saugluft erfolgt demnach über die mindestens eine Lage, indem in Abhängigkeit von ihrer Relativposition gegenüber dem bewegbaren Körper mindestens eine ihrer Durchgangsöffnungen in fluide Verbindung mit mindestens einer gewünschten Saugöffnung in der Außenseite des bewegbaren Körpers gebracht wird. Dies wird erfindungsgemäß dadurch erreicht, dass die mindestens eine Lage gegenüber dem mindestens einen Aufnahmeelement zwischen mindestens einer ersten Arbeitsposition und einer von der ersten Arbeitsposition unterschiedlichen zweiten Arbeitsposition verstellbar ist. Da erfindungsgemäß das mindestens eine Aufnahmeelement am bewegbaren Körper gegenüber diesem stationär anzuordnen ist, führt eine Verstellung der mindestens einen Lage zwischen der ersten Arbeitsposition und mindestens einer zweiten Arbeitsposition auch zu einer entsprechenden Änderung der Relativposition gegenüber dem bewegbaren Körper.The suction openings on the outside of the movable body expediently form a standardized or regular hole profile. In contrast, the passage openings in the at least one layer are to be formed and arranged relative to each other in such a way that in the case of a change in format, in particular the length of the male article, a corresponding adaptation of the Saugluftmusters on the outside of the at least one receiving element and thus the suction behavior of the conveyor Change the position of the situation with respect to the movable body can achieve. Accordingly, the control of the suction air takes place via the at least one layer in that, depending on its relative position relative to the movable body, at least one of its passage openings is brought into fluid communication with at least one desired suction opening in the outside of the movable body. This is inventively achieved in that the at least one position relative to the at least one receiving element between at least one first working position and a different from the first working position second working position is adjustable. Since, according to the invention, the at least one receiving element is to be arranged stationary on the movable body, an adjustment of the at least one position between the first working position and at least one second working position also leads to a corresponding change in the relative position relative to the movable body.
Mithilfe der Erfindung lässt sich ein Formatwechsel, insbesondere hinsichtlich Längenänderungen der Artikel und vorzugsweise von Filtersegmenten, an einer Fördervorrichtung, insbesondere an einer Sammel- bzw. Zusammenstelltrommel in einer Multifilterherstellungsmaschine, besonders einfach durchführen, indem nämlich lediglich die mindestens eine Lage relativ zum bewegbaren Körper in eine andere Arbeitsposition verbracht wird, in der die Durchgangsöffnungen hinsichtlich ihrer Anordnung und/oder Ausbildung an ein anderes Format, insbesondere eine andere Länge, der dann aufzunehmenden Artikel entsprechend angepasst sind.By means of the invention, a format change, in particular with regard to changes in length of the articles, and preferably of filter segments, on a Carrying conveyor, in particular on a collecting or compilation drum in a Multifilterherstellungsmaschine perform particularly simple, namely, only the at least one position relative to the movable body is moved to a different working position in which the through holes in terms of their arrangement and / or training to another Format, in particular a different length, which are then adapted to be included article accordingly.
Ein Vorteil der Erfindung besteht nicht nur in der einfachen Handhabung, sondern auch darin, dass für die Anpassung an ein anderes Format keine Teile getauscht zu werden brauchen. Des Weiteren erlaubt die Erfindung eine standardisierte und somit vereinfachte Ausgestaltung und Fertigung des bewegbaren Körpers der Fördervorrichtung. Denn als bewegbarer Körper der Fördervorrichtung kann ein formatunabhängiger Körper verwendet werden, während in Abhängigkeit von dem jeweiligen Format der zu transportierenden Artikel die mindestens eine Lage einfach nur in eine andere Arbeitsposition verbracht zu werden braucht, in der deren Durchgangsöffnungen hinsichtlich ihrer Anordnung und/oder Ausbildung an ein gewünschtes anderes Format, insbesondere die gewünschte Länge, des aufzunehmenden Artikels angepasst sind.An advantage of the invention is not only in the ease of use, but also in that no parts need to be replaced for adaptation to another format. Furthermore, the invention allows a standardized and thus simplified design and manufacture of the movable body of the conveyor. Because as a movable body of the conveyor, a format-independent body can be used, while depending on the particular format of the article to be transported, the at least one layer just needs to be spent in a different working position, in the through holes in terms of their arrangement and / or training are adapted to a desired other format, in particular the desired length of the male article.
Was die Ausgestaltung des Aufnahmeelementes betrifft, so sind grundsätzlich unterschiedliche Ausführungen denkbar. Beispielsweise kann das Aufnahmeelement im Wesentlichen von einem länglichen und verhältnismäßig dünnen oder flachen Körper gebildet sein, an dessen Außenseite mehrere nebeneinanderliegende Aufnahmeabschnitte ausgebildet sind, von denen jeder Aufnahmeabschnitt mindestens einen Artikel aufnimmt. Bei dieser Ausführung sind in jedem Aufnahmeabschnitt mindestens ein erster Einlass und ein von diesem beabstandeter zweiter Einlass ausgebildet, die jeweils über Verbindungskanäle mit einem ersten bzw. zweiten Auslass an der Innenseite verbunden sind. Der im Wesentlichen das Aufnahmeelement bildende längliche und dünne oder flache Körper ist mit seiner Innenseite im Wesentlichen flächig auf der Lage angeordnet, welche wiederum auf der Außenseite des bewegbaren Körpers der Fördervorrichtung aufliegt. Für den eher häufiger anzutreffenden Fall, dass die Fördervorrichtung als Rotationsfördervorrichtung ausgebildet ist, bei welcher als bewegbarer Körper eine drehbar gelagerte Trommel vorgesehen ist, deren Rotationsrichtung die Förderrichtung definiert, ist der im Wesentlichen das Aufnahmeelement bildende längliche Körper ringförmig ausgebildet, dessen Innendurchmesser an den Außendurchmesser der Trommel angepasst ist, sodass zwischen der Trommel und dem das Aufnahmeelement bildenden ringförmigen Körper lediglich die auswechselbare Lage anzuordnen ist.As far as the design of the receiving element is concerned, fundamentally different designs are conceivable. For example, the receiving element may essentially be formed by an elongated and relatively thin or flat body, on the outside of which a plurality of adjacent receiving sections are formed, of which each receiving section receives at least one article. In this embodiment, at least one first inlet and a second inlet spaced therefrom are formed in each receiving section, which are each connected via connecting channels to a first or second outlet on the inner side. The elongate and thin or flat body essentially forming the receiving element is arranged with its inner side substantially flat on the layer, which in turn rests on the outer side of the movable body of the conveying device. For the more frequently encountered case that the conveyor device is designed as a rotary conveyor, in which as movable Body is provided with a rotatably mounted drum whose direction of rotation defines the conveying direction, the elongated body essentially forming the receiving element is annular, whose inner diameter is adapted to the outer diameter of the drum, so that between the drum and the receiving element forming the annular body only the interchangeable Location is to be arranged.
Bei einer bevorzugten alternativen Ausführung wird (anstelle eines länglichen 'durchgehenden' Körpers) eine Vielzahl von diskreten Aufnahmeelementen verwendet, von denen jeder nur einen einzigen Aufnahmeabschnitt aufweist, der im Wesentlichen von der Ober- bzw. Außenseite des Aufnahmeelementes gebildet wird. Die als diskrete Körper vorgesehenen Aufnahmeelemente werden bei dieser Ausführung nebeneinander auf der Außenseite des bewegbaren Körpers der Fördervorrichtung angeordnet, wobei im Allgemeinen die Befestigung jedes Aufnahmeelementes separat von den übrigen Aufnahmeelementen erfolgt.In a preferred alternative embodiment, a plurality of discrete receiving elements are used (instead of an elongate 'continuous' body), each of which has only a single receiving portion formed substantially from the top and the outside of the receiving element, respectively. In this embodiment, the receiving elements provided as discrete bodies are arranged side by side on the outside of the movable body of the conveying device, with the fastening of each receiving element generally taking place separately from the other receiving elements.
Der guten Vollständigkeit halber sei an dieser Stelle noch angemerkt, dass das mindestens eine Aufnahmeelement nicht nur am bewegbaren Körper gegenüber diesem stationär anzuordnen, sondern zweckmäßigerweise an diesem auch zu befestigen ist, wobei bevorzugt die Befestigung bei Bedarf lösbar ist, um einen Austausch des mindestens einen Aufnahmeelementes gegen ein anderes Aufnahmeelement zu ermöglichen. Ebenfalls sei an dieser Stelle der guten Vollständigkeit halber angemerkt, dass für die mindestens eine am bewegbaren Körper verstellbar anzuordnende Lage bevorzugt noch eine Arretiereinrichtung vorzusehen ist, die die Lage in der jeweils gewählten Arbeitsposition gegenüber dem bewegbaren Körper und somit auch gegenüber dem mindestens einen Aufnahmeelement fixiert und sich nur für den Fall der Verbringung der Lage in eine andere Arbeitsposition lösen lässt.For the sake of completeness, it should be noted at this point that the at least one receiving element is not only to be arranged stationary on the movable body, but expediently also to be fastened to it, the attachment preferably being detachable if necessary in order to replace the at least one To allow receiving element against another receiving element. It should also be noted at this point, for the sake of good completeness, that for the at least one position to be arranged adjustably on the movable body, a locking device is preferably provided which fixes the position in the respectively selected working position relative to the movable body and thus also relative to the at least one receiving element and can only be resolved in the event of transferring the situation to another job position.
Zwar ist die Verwendung einer Lage oder eines Flachteils in einer zum Fördern von Artikeln der Tabak verarbeitenden Industrie vorgesehenen Fördervorrichtung bekannt. So lehrt die
Bevorzugte Ausführungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Preferred embodiments and further developments of the invention are characterized in the dependent claims.
Bevorzugt ist die mindestens eine Lage im Wesentlichen in Förderrichtung verstellbar.Preferably, the at least one layer is substantially adjustable in the conveying direction.
In Abhängigkeit von dem gewünschten Format ist es zweckmäßig, die Durchgangsöffnungen in der mindestens einen Lage derart zu positionieren, dass sich in einer ersten Arbeitsposition der Lage deren Durchgangsöffnungen in fluider Verbindung mit mindestens einem Teil der Saugöffnungen in der Außenseite des bewegbaren Köpers befinden und in einer von der ersten Arbeitsposition unterschiedlichen zweiten Arbeitsposition der Lage mindestens ein Teil der Saugöffnungen in der Außenseite des bewegbaren Körpers von der Lage verschlossen sind. Somit findet in der ersten Arbeitsposition der Lage eine Kopplung eines bestimmten Auslasses oder mehrerer bestimmter Auslässe an der Innenseite des mindestens einen Aufnahmeelementes mit bestimmten Saugöffnungen in der Außenseite des bewegbaren Körpers statt, während in der zweiten Arbeitsposition bestimmte Saugöffnungen und insbesondere die zuvor erwähnten bestimmten Saugöffnungen in der Außenseite des bewegbaren Körpers von der Lage verschlossen und somit deaktiviert sind.Depending on the desired format, it is expedient to position the passage openings in the at least one layer in such a way that, in a first working position of the layer, their passage openings are in fluid communication with at least part of the suction openings in the outside of the movable body and in one from the first working position different second working position of the position at least a part of the suction openings in the outside of the movable body are closed by the position. Thus, in the first working position of the ply, a coupling of a particular outlet or outlets on the inside of the at least one receiving element with certain suction openings in the outside of the movable body takes place while in the second working position certain suction openings and in particular those previously mentioned are determined Suction openings in the outside of the movable body are closed by the layer and thus deactivated.
In Abhängigkeit von den gewünschten unterschiedlichen Formaten kann das ferner von Vorteil sein, beispielsweise die Durchgangsöffnungen in der mindestens einen Lage derart zu positionieren, dass in einer ersten Arbeitsposition der Lage sich deren mindestens eine Durchgangsöffnung in fluider Verbindung mit der mindestens einen ersten Saugöffnung in der Außenseite des bewegbaren Körpers befindet und die mindestens eine zweite Saugöffnung in der Außenseite des bewegbaren Körpers von der Lage verschlossen ist, in einer von der ersten Arbeitsposition unterschiedlichen zweiten Arbeitsposition der Lage sich deren mindestens eine Durchgangsöffnung in fluider Verbindung mit der mindestens einen zweiten Saugöffnung in der Außenseite des bewegbaren Körpers befindet und die mindestens eine erste Saugöffnung in der Außenseite des bewegbaren Körpers von der Lage verschlossen ist und in einer von den ersten und zweiten Arbeitspositionen unterschiedlichen dritten Arbeitsposition der Lage die Saugöffnungen des bewegbaren Körpers von der Lage verschlossen sind. Bei dieser Ausführung lassen sich somit für mindestens einen Auslass an der Innenseite des mindestens einen Aufnahmeelementes drei Zustände definieren, nämlich (1.) Kopplung mit der mindestens einen ersten Saugöffnung in der Außenseite des bewegbaren Körpers, (2.) Kopplung mit der mindestens einen zweiten Saugöffnung in der Außenseite des bewegbaren Körpers und (3.) Sperrung, d.h. keine Kopplung mit Saugöffnungen in der Außenseite des bewegbaren Körpers.Depending on the desired different formats, it may further be advantageous to position, for example, the passage openings in the at least one layer such that in a first working position of the layer, the at least one passage opening is in fluid communication with the at least one first suction opening in the outside the movable body is located and the at least one second suction opening in the outer side of the movable body is closed by the layer, in a second working position of the layer different from the first working position, the at least one passage opening in fluid communication with the at least one second suction opening in the outer side the movable body is located and the at least one first suction opening in the outer side of the movable body is closed by the layer and in a different from the first and second working positions third working position of the L. age the suction openings of the movable body are closed by the situation. In this embodiment, three states can thus be defined for at least one outlet on the inside of the at least one receiving element, namely (1) coupling with the at least one first suction opening in the outside of the movable body, (2) coupling with the at least one second Suction opening in the outside of the movable body and (3.) blocking, ie no coupling with suction openings in the outside of the movable body.
Eine derartige Ausführung ist beispielsweise auch für eine zum Fördern der Artikel ausgebildete Fördervorrichtung geeignet, deren bewegbarer Körper an seiner Außenseite, bevorzugt in einer standardisierten Anordnung, mindestens eine Gruppe von ersten Saugöffnungen und mindestens eine von der Gruppe der ersten Saugöffnungen beabstandete Gruppe von zweiten Saugöffnungen aufweist, wobei die Durchgangsöffnungen in der mindestens einen Lage derart positioniert sind, dass in einer ersten Arbeitsposition der Lage sich deren Durchgangsöffnungen in fluider Verbindung mit den ersten Saugöffnungen in der Außenseite des bewegbaren Körpers befinden und die zweiten Saugöffnungen in der Außenseite des bewegbaren Körpers von der Lage verschlossen sind, in einer von der ersten Arbeitsposition unterschiedlichen zweiten Arbeitsposition der Lage sich deren Durchgangsöffnungen in fluider Verbindung mit den zweiten Saugöffnungen in der Außenseite des bewegbaren Körpers befinden und die ersten Saugöffnungen in der Außenseite des bewegbaren Körpers von der Lage verschlossen sind und in einer von den ersten und zweiten Arbeitspositionen unterschiedlichen dritten Arbeitsposition der Lage die Saugöffnungen in der Außenseite des bewegbaren Körpers von der Lage verschlossen sind.Such an embodiment is also suitable, for example, for a conveying device designed to convey the articles, whose movable body has on its outer side, preferably in a standardized arrangement, at least one group of first suction openings and at least one group of second suction openings spaced from the group of the first suction openings wherein the passage openings in the at least one layer are positioned such that in a first working position of the sheet, their through holes are in fluid communication with the first suction holes in the outside of the movable body and the second suction holes in the outside of the movable body are in position are closed, in a second working position of the sheet different from the first working position, the through-holes of which are in fluid communication with the second suction holes in the outside of the movable body and the first suction holes in the outside of the movable body are closed by the sheet and in one of the first and second holes Working positions different third working position of the situation the suction openings in the outside of the movable body are closed by the situation.
Bei einer Weiterbildung der zuvor beschriebenen Ausführung, die für eine zum Fördern der Artikel ausgebildete Fördervorrichtung geeignet ist, deren bewegbarer Körper in seiner Außenseite eine etwa quer zur Förderrichtung verlaufende erste Nut, die in eine erste Saugöffnung mündet, eine benachbart zur ersten Nut etwa quer zur Förderrichtung verlaufende zweite Nut, in die eine zweite Saugöffnung mündet, und einen benachbart zur zweiten Nut etwa quer zur Förderrichtung verlaufenden Steg aufweist, ist die mindestens eine Durchgangsöffnung in der mindestens einen Lage derart positioniert, dass in der ersten Arbeitsposition der Lage sich die Durchgangsöffnung in fluider Verbindung mit der ersten Nut in der Außenseite des bewegbaren Körpers befindet und ein zur Durchgangsöffnung benachbarter Abschnitt der Lage die zweite Nut in der Außenseite des bewegbaren Körpers bedeckt, in der zweiten Arbeitsposition der Lage sich die Durchgangsöffnung in fluider Verbindung mit der zweiten Nut in der Außenseite des bewegbaren Körpers befindet und der zur Durchgangsöffnung benachbarte Abschnitt der Lage die erste Nut in der Außenseite des bewegbaren Körpers bedeckt und in der dritten Position der Lage sich deren Durchgangsöffnung über dem Steg befindet und der zur Durchgangsöffnung benachbarte Abschnitt gemeinsam die ersten und zweiten Saugöffnungen in der Außenseite des bewegbaren Körpers bedeckt. Diese Weiterbildung erlaubt nicht nur eine einfache Ausbildung der mindestens einen Lage, sondern auch eine einfache Ausrichtung der Lage quer zur Förderrichtung, da durch die Ausbildung der Nuten in der Außenseite des bewegbaren Körpers im Wesentlichen unabhängig von der Ausrichtung der Lage quer zur Förderrichtung deren mindestens eine Durchgangsöffnung in der ersten Arbeitsposition in fluchtende Anordnung mit der ersten Nut und somit in fluide Verbindung mit der ersten Saugöffnung und in der zweiten Arbeitsposition in fluchtende Anordnung mit der zweiten Nut und somit in fluide Verbindung mit der zweiten Saugöffnung gelangt.In a further development of the embodiment described above, which is suitable for a conveying device designed for conveying the article whose movable body in its outer side extending approximately transversely to the conveying direction of the first groove, which opens into a first suction opening, adjacent to the first groove approximately transversely to Conveying direction extending second groove into which opens a second suction opening, and has an adjacent to the second groove extending transversely to the conveying direction web, the at least one through hole in the at least one layer is positioned such that in the first working position of the position, the passage opening in is fluidly connected to the first groove in the outer side of the movable body and an adjacent to the passage opening portion of the layer covers the second groove in the outer side of the movable body, in the second operating position of the position, the passage opening in fluid communication with the zw Nut is in the outer side of the movable body and adjacent to the passage opening portion of the layer covers the first groove in the outer side of the movable body and in the third position of the layer whose passage opening is located above the web and the passage adjacent to the adjacent portion together the first and second suction openings in the outside of the movable body covered. This development allows not only a simple formation of the at least one layer, but also a simple orientation of the position transversely to the conveying direction, as by forming the grooves in the outside of the movable body substantially independent of the orientation of the position transversely to the conveying direction whose at least one Through opening in the first working position in alignment with the first groove and thus in fluid communication with the first suction port and in the second working position in alignment with the second groove and thus in fluid communication with the second suction port.
Bei einer weiterführenden Ausgestaltung der zuvor beschriebenen Weiterbildung, welche für eine zum Fördern der Artikel ausgebildete Fördervorrichtung geeignet ist, deren bewegbarer Körper mehrere jeweils von der ersten Nut, der zweiten Nut und dem Steg gebildete Anordnungen aufweist, enthält die Lage mehrere Durchgangsöffnungen, wobei der Abstand jeweils zweier benachbarter Durchgangsöffnungen voneinander im Wesentlichen dem Abstand zwischen den ersten Nuten von jeweils zwei benachbarten Anordnungen in der Außenseite des bewegbaren Körpers entspricht. Demnach entspricht die Teilung der ersten Nuten der Teilung der Durchgangsöffnungen.In a further refinement of the further development described above, which is suitable for a conveying device designed to convey the articles, whose movable body has a plurality of respective arrangements formed by the first groove, the second groove and the web, the layer contains a plurality of passage openings, wherein the distance each two adjacent passage openings from one another substantially corresponds to the distance between the first grooves of each two adjacent arrangements in the outer side of the movable body. Accordingly, the pitch of the first grooves corresponds to the pitch of the through holes.
Vorzugsweise ist die mindestens eine Lage als sich im Wesentlichen in Förderrichtung erstreckender Streifen ausgebildet.The at least one layer is preferably designed as a strip extending essentially in the conveying direction.
Die mindestens eine Lage kann bevorzugt nur eine im Wesentlichen in Förderrichtung verlaufende Reihe von Durchgangsöffnungen aufweisen, so dass bei dieser Ausführung die Durchgangsöffnungen auf einer in Förderrichtung verlaufenden virtuellen Linie angeordnet sind. Mit anderen Worten sind bei dieser Ausführung die Durchgangsöffnungen einreihig angeordnet.The at least one layer may preferably have only one row of passage openings extending essentially in the conveying direction, so that in this embodiment the passage openings are arranged on a virtual line running in the conveying direction. In other words, in this embodiment, the through holes are arranged in a single row.
Insbesondere wenn eine Mehrzahl von auswechselbaren, diskreten Aufnahmeelementen verwendet wird, weist bevorzugt das mindestens eine Aufnahmeelement in einer standardisierten Anordnung an seiner die Artikel aufnehmenden Außenseite mehrere nebeneinanderliegende Einlässe und an seiner Innenseite mehrere nebeneinanderliegende Auslässe auf, wobei die Anzahl der Einlässe und der Auslässe gleich ist und jeweils ein Einlass über einen Verbindungskanal mit einem Auslass verbunden ist. Dabei kann bevorzugt jeweils ein Einlass im Wesentlichen über einem Auslass liegen.In particular, when a plurality of interchangeable, discrete receiving elements is used, preferably the at least one receiving element in a standardized arrangement at its article receiving outside a plurality of adjacent inlets and on its inside a plurality of juxtaposed outlets, wherein the number of inlets and outlets is the same and each inlet is connected to an outlet via a connection channel. In this case, preferably, in each case one inlet can lie substantially above an outlet.
Ferner sind vorzugsweise die Auslässe an der Innenseite des mindestens einen Aufnahmeelementes im Wesentlichen quer zur Förderrichtung nebeneinander angeordnet. Dies ist insbesondere für die Aufnahme von länglichen Artikeln vorteilhaft, wenn diese quer zu Ihrer Längserstreckung zu transportieren sind.Furthermore, the outlets on the inside of the at least one receiving element are preferably substantially adjacent to one another, transversely to the conveying direction arranged. This is particularly advantageous for receiving elongate articles if they are to be transported transversely to their longitudinal extent.
Zur Erzeugung unterschiedlicher Lochmuster ist es von Vorteil, mindestens zwei quer zur Förderrichtung zueinander benachbart und/oder beabstandet angeordnete Lagen vorzusehen. Bei einer Weiterbildung dieser Ausführung kann die Anzahl der Lagen gleich der an einem Aufnahmeelement vorgesehenen Anzahl der Auslässe sein, wenn die Lage nur eine einreihige Anordnung von Durchgangsöffnungen in Förderrichtung aufweist.In order to produce different hole patterns, it is advantageous to provide at least two layers arranged adjacent to one another and / or spaced apart from one another in relation to the conveying direction. In a further development of this embodiment, the number of layers may be equal to the number of outlets provided on a receiving element when the layer has only a single-row arrangement of passage openings in the conveying direction.
Im Falle der Verwendung einer Vielzahl von Aufnahmeelementen, die in Förderrichtung des bewegbaren Körpers der Fördervorrichtung hintereinander angeordnet sind, sollte vorzugsweise der Abstand zwischen in Förderrichtung benachbarten Durchgangsöffnungen in der mindestens einen Lage im Wesentlichen dem Abstand zwischen dem Auslass eines Aufnahmeelementes und einem Auslass des benachbarten Aufnahmeelementes in Förderrichtung entsprechen. Somit ist bei dieser Ausführung die Teilung der Durchgangsöffnungen im Wesentlichen gleich dem Abstand zwischen den Auslässen zweier benachbarter Aufnahmeelemente, der im Übrigen auch dem Abstand zwischen den Mittellinien zweier benachbarter Aufnahmeelemente entspricht.In the case of using a plurality of receiving elements, which are arranged one behind the other in the conveying direction of the movable body of the conveying device, preferably the distance between adjacent in the conveying direction passage openings in the at least one layer substantially the distance between the outlet of a receiving element and an outlet of the adjacent receiving element in the conveying direction. Thus, in this embodiment, the pitch of the passage openings is substantially equal to the distance between the outlets of two adjacent receiving elements, which also corresponds to the distance between the center lines of two adjacent receiving elements.
Insbesondere im Falle der Verwendung einer Mehrzahl von auswechselbaren, diskreten Aufnahmeelementen ist bevorzugt ein Rahmen vorgesehen, in den das mindestens eine Aufnahmeelement lösbar einsetzbar ist, wobei der Rahmen auf der Lage anzuordnen ist. Vorzugsweise enthält der Rahmen eine Vielzahl von Durchbrüchen, die in Förderrichtung des bewegbaren Körpers der Fördervorrichtung hintereinander angeordnet und zur Aufnahme der Aufnahmeelemente ausgebildet sind. Die Verwendung eines derartigen Rahmens ermöglicht auf konstruktiv einfache, jedoch geschickte Weise eine definierte Anordnung der Aufnahmeelemente in Bezug auf die Lage und die Außenseite des bewegbaren Körpers der Fördervorrichtung; denn eine definierte Anordnung dieser drei Komponenten relativ zueinander ist wichtig, um zwischen den Auslässen an der Innenseite der Aufnahmeelemente, den Durchgangsöffnungen in der Lage und den Saugöffnungen in der Außenseite des bewegbaren Körpers der Fördervorrichtung jeweils eine Fluidverbindung herzustellen.In particular, in the case of using a plurality of interchangeable, discrete receiving elements, a frame is preferably provided, in which the at least one receiving element is detachably insertable, wherein the frame is to be arranged on the layer. Preferably, the frame includes a plurality of openings, which are arranged one behind the other in the conveying direction of the movable body of the conveying device and designed to receive the receiving elements. The use of such a frame allows a structurally simple, yet clever way a defined arrangement of the receiving elements with respect to the position and the outside of the movable body of the conveyor; because a defined arrangement of these three components relative to each other is important to between the outlets on the inside of the receiving elements, the through holes in the position and the Suction openings in the outer side of the movable body of the conveying device each produce a fluid connection.
Bevorzugt ist die Fördervorrichtung als Rotationsfördervorrichtung ausgebildet, die als bewegbaren Körper eine drehbar gelagerte Trommel aufweist, deren Rotationsrichtung die Förderrichtung definiert, bei welcher die mindestens eine Lage als in Förderrichtung umlaufender Ring ausgebildet ist.Preferably, the conveying device is designed as a rotary conveying device, which has as a movable body a rotatably mounted drum whose direction of rotation defines the conveying direction, in which the at least one layer is designed as a circumferential ring in the conveying direction.
Zweckmäßigerweise weist die Außenseite des mindestens einen Aufnahmeelementes eine längliche Nut oder Mulde auf oder bildet eine Nut oder eine Mulde, die im Wesentlichen quer zur Förderrichtung des bewegbaren Körpers der Fördervorrichtung orientiert ist.Expediently, the outer side of the at least one receiving element has an elongated groove or trough or forms a groove or a trough which is oriented substantially transversely to the conveying direction of the movable body of the conveying device.
Insbesondere für den Fall, dass eine Vielzahl von diskreten Aufnahmeelementen vorzusehen ist, weist das mindestens eine Aufnahmeelement einen länglichen Körper mit zwei Langseiten auf, der im Wesentlichen quer zur Förderrichtung des bewegbaren Körpers der Fördervorrichtung anzuordnen ist.In particular, in the event that a plurality of discrete receiving elements is to be provided, the at least one receiving element has an elongate body with two long sides, which is to be arranged substantially transversely to the conveying direction of the movable body of the conveying device.
Schließlich kann zweckmäßigerweise das Aufnahmeelement als einstückiger Körper ausgebildet sein.Finally, the receiving element can expediently be designed as a one-piece body.
