In this case, the containers can be designed as standard trays with an undivided receiving space for the products or with a receiving space divided into individual trays be. For further processing of the stored products, these are delivered to downstream devices, such as packaging machines or the like, or introduced into an existing mass flow. The so-called emptying stations are usually available for the automated supply or emptying of the trays or shaft trays. The emptying stations have in a known manner a supply for products filled with containers, an emptying magazine, a discharge for the emptied containers and a transfer device, by means of the full container from the feed in the region of the emptying magazine and the empty container from the emptying magazine in the area the removal be transported. The emptying station can also consist of the emptying magazine alone, the containers are then emptied manually, for example, in the emptying magazine.

Das Entleermagazin dient dazu, die aus den Behältern strömenden Produkte kontinuierlich und gleichmäßig über das den Aufnahmeraum nach unten begrenzende Förderelement abzuführen und den nachgeordneten Vorrichtungen oder dergleichen zuzuführen. Ein solches Entleermagazin ist beispielsweise der DE 10 2007 005 749 A1 zu entnehmen. Das darin beschriebene Entleermagazin weist die Merkmale des Oberbegriffes des Anspruches 1 auf. Im Aufnahmeraum dieses Entleermagazins sind mehrere Stromregulierungselemente angeordnet, die mehrere parallel zueinander verlaufende, vertikal gerichtete Kanäle bilden. Die vertikal gerichteten Kanäle münden in einen durch das Förderelement gebildeten, horizontal verlaufenden Kanal, durch den die Produkte in einem gemeinsamen Massenstrom abtransportiert werden. Der Abstand zwischen den Stromregulierungselementen und dem Förderelement ist einstellbar, indem die Kontur der Stromregulierungselemente verändert wird. Anders ausgedrückt sind die Stromregulierungselemente teleskopartig ausgebildet und werden in Abhängigkeit des Füllstands wahlweise auseinander gezogen oder zusammen gefahren. Diese Ausbildung des Entleermagazins ist jedoch zum einen konstruktiv aufwendig. Zum anderen verläuft der Entleervorgang ungleichmäßig.The emptying magazine serves to remove the products flowing from the containers continuously and uniformly over the conveying space delimiting the receiving space down and supply the downstream devices or the like. Such an emptying magazine is for example the DE 10 2007 005 749 A1 refer to. The emptying magazine described therein has the features of the preamble of claim 1. In the receiving space of this emptying magazine several power regulating elements are arranged, which form a plurality of mutually parallel, vertically directed channels. The vertically directed channels open into a horizontal channel formed by the conveying element, through which the products are transported away in a common mass flow. The distance between the current regulating elements and the conveying element is adjustable by changing the contour of the current regulating elements. In other words, the current regulating elements are telescopically formed and are optionally pulled apart or driven together depending on the level. However, this training of the emptying magazine is structurally complex. On the other hand, the emptying process is uneven.

Der Erfindung liegt damit die Aufgabe zugrunde, ein einfaches und hinsichtlich des Entleervorgangs optimiertes Entleermagazin zu schaffen. Des Weiteren ist es Aufgabe der Erfindung, ein entsprechendes Verfahren vorzuschlagen.The invention is therefore an object of the invention to provide a simple and with regard to the emptying optimized emptying magazine. Furthermore, it is an object of the invention to propose a corresponding method.

Die Aufgabe wird durch ein Entleermagazin der eingangs genannten Art dadurch gelöst, dass der Neigungswinkel α und der Abstand zwischen dem Förderelement und jedem Stromregulierungselement in Abhängigkeit der Durchmesser der Produkte durch Verstellbarkeit jedes Stromregulierungselementes unter Beibehaltung seiner Kontur und des Förderelementes einstellbar sind, wobei der Neigungswinkel α des Förderelementes unabhängig von der Abstandseinstellbarkeit verstellbar ist, wobei dem Förderelement ein Antrieb zur Verstellung des Neigungswinkels α zugeordnet ist, und dass alle Stromregulierungselemente an einem Träger angeordnet sind, wobei der Träger in der Höhe vertikal verstellbar ist und dem Träger zwei Antriebe zur Verstellung der Höhe der Stromregulierungselemente in Bezug auf das Förderelement zugeordnet sind, und dass der jeweilige Durchmesser der Produkte über ein Eingabefeld eingebbar ist, um die Antriebe zu steuern. Mit dieser erfindungsgemäßen Ausbildung wird ein gleichmäßiger und besser nachvollziehbarer Produktfluss erreicht, was die Funktionssicherheit des Entleermagazins erhöht. Durch das geneigte Förderelement wird nämlich erreicht, dass alle Produkte unabhängig von ihrer Position innerhalb des Schragen bzw. Schachtschragen bis zum Erreichen des Förderelementes nahezu gleiche Wege nehmen. Des Weiteren wird eine konstruktiv einfache Ausbildung erreicht, da die Kontur der Stromregulierungselemente beibehalten wird. Anders ausgedrückt werden wahlweise die Stromregulierungselemente als Ganzes und/oder das Förderelement verstellt, wodurch eine einfache und reproduzierbare Grundeinstellung des Entleermagazins erreicht wird. Durch die erfindungsgemäße Ausbildung, nämlich die Verstellbarkeit des Neigungswinkels α und/oder des Abstands, wird weiterhin erreicht, dass ein automatischer Formatwechsel insbesondere in Bezug auf den Durchmesser der Produkte unterstützt wird. Dadurch, dass der Neigungswinkel und der Abstand unabhängig voneinander einstellbar sind, ist das Förderelement derart unterhalb des Aufnahmeraums bzw. unterhalb der Stromregulierungselemente anzuordnen, dass aus jedem der vertikal gerichteten Kanäle die gleiche Produktlagen-Anzahl gebildet werden kann, was den Produktfluss weiter verbessert. Gleichzeitig wird durch die gleichmäßige Lagenbildung und Verteilung der Produkte die mechanische Beanspruchung der Produkte reduziert. Insbesondere wird ein übermäßiges Rollen der Produkte verhindert. Dadurch, dass alle Stromregulierungselemente an einem Träger angeordnet sind, wobei der Träger in der Höhe vertikal verstellbar ist, sind die Einstellung und Reproduzierbarkeit der Einstellung wesentlich vereinfacht.The object is achieved by an emptying magazine of the type mentioned above in that the angle of inclination α and the distance between the conveying element and each current regulating element as a function of the diameter of the products Adjustability of each current regulating element while maintaining its contour and the conveying element are adjustable, the inclination angle α of the conveying element is independent of the Abstandseinstellbarkeit adjustable, wherein the conveying element is assigned a drive for adjusting the inclination angle α, and that all current regulating elements are arranged on a support, wherein the support is vertically adjustable in height and the carrier is associated with two drives for adjusting the height of the Stromregulierungselemente with respect to the conveying element, and that the respective diameter of the products can be entered via an input field to control the drives. With this embodiment of the invention, a more uniform and better traceable product flow is achieved, which increases the reliability of the discharge magazine. By the inclined conveyor element is namely achieved that take all products, regardless of their position within the Schragen or Schachtschragen until reaching the conveying element almost the same way. Furthermore, a structurally simple design is achieved because the contour of the current regulating elements is maintained. In other words, optionally the flow regulating elements as a whole and / or the conveying element are adjusted, whereby a simple and reproducible basic setting of the discharge magazine is achieved. The inventive design, namely the adjustability of the inclination angle α and / or the distance, is further achieved that an automatic format change is supported in particular with respect to the diameter of the products. Characterized in that the inclination angle and the distance are independently adjustable, the conveying element is to be arranged below the receiving space or below the Stromregulierungselemente that from each of the vertically directed channels the same number of product layers can be formed, which further improves the product flow. At the same time, the uniform application of the layers and distribution of the products reduces the mechanical stress on the products. In particular, an excessive rolling of the products is prevented. Characterized in that all current-regulating elements are arranged on a support, wherein the support is vertically adjustable in height, the adjustment and reproducibility of the setting are much easier.

Vorteilhafterweise sind sämtliche Stromregulierungselemente identisch ausgebildet. Damit wird erreicht, dass auch die vertikal gerichteten Kanäle gleich gestaltet sind, wodurch die Unterschiede bezüglich der Wegstrecke, die die Produkte in den unterschiedlichen Kanälen nehmen, weiter minimiert werden.Advantageously, all current regulating elements are identical. This ensures that the vertically directed channels are designed the same, whereby the differences in the distance that take the products in the different channels are further minimized.

Die Aufgabe wird auch durch ein Verfahren mit den eingangs genannten Schritten dadurch gelöst, dass die Produkte in dem Kanal schräg nach unten abtransportiert werden und der Neigungswinkel α und der Abstand zwischen dem Förderelement und jedem Stromregulierungselement in Abhängigkeit der Durchmesser der Produkte eingestellt werden, wobei die Neigung des Förderelementes unabhängig vom Abstand zwischen dem Förderelement und den Stromregulierungselementen verstellt wird, und dass alle Stromregulierungselemente gleichzeitig über einen gemeinsamen Träger in der Höhe verstellt werden, wobei der jeweilige Durchmesser der Produkte über ein Eingabefeld eingegeben wird, um Antriebe zum Verstellen der Neigung und zum Verstellen der Stromregulierungselemente zu steuern. Die sich daraus ergebenden Vorteile wurden bereits im Zusammenhang mit dem Entleermagazin erläutert, so dass zur Vermeidung von Wiederholungen auf die entsprechenden Passagen verwiesen wird.The object is also achieved by a method with the steps mentioned above, that the products are transported away in the channel obliquely downwards and the inclination angle α and the distance between the conveyor element and each current regulating element depending on the diameter of the products are set, the Inclination of the conveying element is adjusted independently of the distance between the conveying element and the current regulating elements, and that all current regulating elements are adjusted simultaneously via a common support in height, wherein the respective diameter of the products is input via an input field to drives for adjusting the inclination and Adjust the flow control elements to control. The resulting benefits have already been explained in connection with the emptying magazine, so that reference is made to avoid repetition of the corresponding passages.

Die in der Zeichnung dargestellten Entleermagazine dienen zum Entleeren von mit stabförmigen Produkten gefüllten Behältern an einer Schragenstation, können jedoch auch als separate Einheit eingesetzt werden.The emptying magazines shown in the drawing are used to empty containers filled with rod-shaped products at a Schragenstation, but can also be used as a separate unit.

Eine erste Ausführungsform eines Entleermagazins 10 umfasst einen Aufnahmeraum 11 für die aus Behältern 12, beispielsweise Schragen oder Schachtschragen, strömenden Produkte. Der Aufnahmeraum 11 ist zu allen Seiten begrenzt. Das bedeutet, dass derA first embodiment of an emptying magazine 10 comprises a receiving space 11 for the products flowing from containers 12, for example trays or shaft trays. The receiving space 11 is limited to all sides. This means that the

Aufnahmeraum 11 durch Seitenwände 13, 14, eine Vorderwand 15 (der besseren Übersicht halber in der Darstellung weggelassen) und eine Rückwand 16 begrenzt ist. Nach oben hin, in Richtung des Behälters 12 ist der Aufnahmeraum offen ausgebildet und optional durch geeignete Schließelemente abgedeckt. Nach unten ist der Aufnahmeraum 11 durch ein Förderelement 17 begrenzt. Das Förderelement 17 ist beabstandet zum Aufnahmeraum 11 angeordnet, so dass das Förderelement 17 einen Kanal 18 bildet, in dem die Produkte abtransportiert werden. Innerhalb des Aufnahmeraums 11 ist mindestens ein Stromregulierungselement 19 angeordnet. Vorzugsweise sind jedoch mehrere Stromregulierungselemente 19 vorgesehen. In Abhängigkeit der Breite der zu entleerenden Behälter 12 können z.B. 2 oder 3 Stromregulierungselemente 19 angeordnet sein. Die Stromregulierungselemente 19 sind so in dem Aufnahmeraum 11 angeordnet, dass sie den Aufnahmeraum 11 vorzugsweise im Auslaufbereich der Produkte aus dem Aufnahmeraum 11 in vertikal gerichtete Kanäle 20 teilen. Bei drei Stromregulierungselementen 19 sind vier parallel verlaufende Kanäle 20 ausgebildet, wobei im Bereich der Seitenwände 13, 14 angepasste Stromregulierungselemente 21 vorgesehen sind. Die Stromregulierungselemente 19, 21 dienen insbesondere zur Steuerung des Produktstroms innerhalb des Entleermagazins 10. Unterhalb der Stromregulierungselemente 19, 21 ist das Förderelement 17 angeordnet. Der Abstand zwischen dem Förderelement 17 und dem oder jedem Stromregulierungselement 19, 21 ist einstellbar.Receiving space 11 by side walls 13, 14, a front wall 15 (the sake of clarity omitted in the illustration) and a rear wall 16 is limited. At the top, in the direction of the container 12, the receiving space is open and optionally covered by suitable closing elements. Down the receiving space 11 is limited by a conveying element 17. The conveying element 17 is arranged at a distance from the receiving space 11 so that the conveying element 17 forms a channel 18 in which the products are transported away. Within the receiving space 11, at least one current regulating element 19 is arranged. Preferably, however, a plurality of current regulating elements 19 are provided. Depending on the width of the containers 12 to be emptied, e.g. 2 or 3 flow regulating elements 19 may be arranged. The current regulating elements 19 are arranged in the receiving space 11 so that they preferably divide the receiving space 11 in the outlet region of the products from the receiving space 11 into vertically directed channels 20. In three current regulating elements 19 four parallel channels 20 are formed, wherein in the region of the side walls 13, 14 adapted power regulating elements 21 are provided. The current regulating elements 19, 21 are used in particular for controlling the product flow within the emptying magazine 10. Below the current regulating elements 19, 21, the conveying element 17 is arranged. The distance between the conveying element 17 and the or each current regulating element 19, 21 is adjustable.

Das den Kanal 18 bildende Förderelement 17 zum Abtransport der Produkte ist in Bezug auf den Aufnahmeraum 11 bzw. auf die Stromregulierungselemente 19, 21 geneigt angeordnet. Anders ausgedrückt verläuft das Förderelement 17 beginnend von einer Seitenwand 14 schräg nach unten, so dass der Abstand des Förderelementes 17 von der einen Seitenwand 14 geringer ist als von der gegenüber liegenden Seitenwand 13. Der Abstand zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21 ist in Abhängigkeit der Durchmesser der Produkte einstellbar. Dazu sind wahlweise die Stromregulierungselemente 19, 21 unter Beibehaltung ihrer Kontur, also als Ganzes, und/oder das Förderelement verstellbar. Mit anderen Worten sind die Stromregulierungselemente 19, 21 bei gleich bleibender Form/Gestalt oder das Förderband auf und ab bewegbar. Auch eine überlagerte Bewegung von Stromregulierungselementen 19, 21 einerseits und Förderelement 21 andererseits ist möglich.The channel 18 forming conveyor element 17 for transporting the products is arranged inclined with respect to the receiving space 11 and to the current regulating elements 19, 21. In other words, starting from a side wall 14, the conveyor element 17 extends obliquely downward, so that the distance of the conveyor element 17 from the one side wall 14 is less than from the opposite side wall 13. The distance between the conveyor element 17 and the current regulating elements 19, 21 adjustable depending on the diameter of the products. For this purpose, either the current regulating elements 19, 21 while maintaining their contour, ie as a whole, and / or the conveying element adjustable. In other words, the current regulating elements 19, 21 with the same shape / shape or the conveyor belt are movable up and down. Also a superimposed movement of Stromregulierungselemente 19, 21 on the one hand and conveying element 21 on the other hand is possible.

Wie bereits erwähnt, ist das Förderelement 17 derart unterhalb des Aufnahmeraums 11 bzw. der Stromregulierungselemente 19, 21 geneigt positioniert, dass aus jedem der vertikal verlaufenden Kanäle 20 die gleiche Produktlagen-Anzahl gebildet wird. Der Neigungswinkel α des Förderelementes 17 ist in Abhängigkeit der Durchmesser der Produkte, vorzugsweise jedoch unabhängig von der Abstandseinstellbarkeit der Stromregulierungselemente 19, 21 und/oder des Förderelementes 17 verstellbar. Die Abstandseinstellbarkeit erfolgt ebenfalls in Abhängigkeit der Durchmesser der Produkte. Zur Einstellbarkeit des Abstands zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21 sind die Stromregulierungselemente 19, 21 als Ganzes und/oder das Förderelement 17 in linearer Richtung in der Höhe verstellbar ausgebildet. Bevorzugt ist das Förderelement 17 - mit Ausnahme der Verstellbarkeit des Neigungswinkels α - ortsfest, während die Stromregulierungselemente 19, 21 als Einheit alle synchronisiert auf und ab bewegbar sind. Neben dem Durchmesser der Produkte kann als weiteres Kriterium die Gesamthöhe des Massenstroms berücksichtigt werden. In der Tabak verarbeitenden Industrie haben sich insbesondere die Höhen 80mm, 100mm und 120mm für den abzutransportierenden Massenstrom durchgesetzt.As already mentioned, the conveying element 17 is positioned below the receiving space 11 or the current regulating elements 19, 21 in such a way that the same number of product layers is formed from each of the vertically extending channels 20. The inclination angle α of the conveying element 17 is adjustable as a function of the diameter of the products, but preferably independent of the distance adjustability of the current regulating elements 19, 21 and / or the conveying element 17. The Abstandseinstellbarkeit also takes place depending on the diameter of the products. For adjustability of the distance between the conveying element 17 and the current regulating elements 19, 21, the current regulating elements 19, 21 as a whole and / or the conveying element 17 are adjustable in height in a linear direction. Preferably, the conveying element 17 - with the exception of the adjustability of the inclination angle α - stationary, while the current regulating elements 19, 21 are all synchronized up and down movable. In addition to the diameter of the products can be considered as a further criterion, the total height of the mass flow. In the tobacco processing industry in particular the heights 80mm, 100mm and 120mm have prevailed for the mass flow to be removed.

Dazu sind alle Stromregulierungselemente 19, 21 an einem gemeinsamen Träger 22 angeordnet, der in der Höhe vertikal verstellbar ist. Dem Träger 22 ist mindestens ein Antrieb 23 zugeordnet. Vorzugsweise sind aber zwei Antriebe 23, 24 vorgesehen, die bevorzugt als Spindelantriebe ausgebildet sind. Selbstverständlich kann der Träger 22 auch manuell, z.B. über Gewindestangen, Handkurbeln oder dergleichen, betätigbar sein. Auf dem Träger 22 selbst sind die Stromregulierungselemente 19, 21 optional auch in horizontaler Richtung verstellbar angeordnet, so dass die Breite der vertikal gerichteten Kanäle 20 einstellbar ist. Auch kann die Anzahl der Stromregulierungselemente 19, 21 variiert werden. Grundsätzlich sind alle Stromregulierungselemente 19, 21 identisch ausgebildet. In erster Linie trifft das auf die frei im Aufnahmeraum 11 angeordneten Stromregulierungselemente 19 zu. Allerdings sind auch die an den Seitenwänden 13, 14 liegenden Stromregulierungselemente 21 identisch zueinander. Gegenüber den frei im Aufnahmeraum 11 angeordneten Stromregulierungselementen 19 sind die an den Außenseiten liegenden Stromregulierungselemente 21 lediglich geteilt ausgebildet, so dass sie einerseits an die Seitenwände 13, 14 angepasst sind und andererseits auf der den Kanälen 20 zugewandten Seite identisch zu den Stromregulierungselementen 19 sind. In der Höhe, die wesentlich die Gestalt und Ausbildung der Kanäle 20 bestimmt, weisen alle Stromregulierungselemente 19, 21 gleiche Abmessungen auf. Auch sind die Abstände zwischen den Stromregulierungselementen 19, 21 gleich, so dass die Kanäle 20 nicht nur in der Höhe sondern auch in der Breite gleich sind.For this purpose, all current regulating elements 19, 21 are arranged on a common carrier 22, which is vertically adjustable in height. The carrier 22 is assigned at least one drive 23. Preferably, however, two drives 23, 24 are provided, which are preferably designed as spindle drives. Of course, the carrier 22 also manually, for example via threaded rods, winches or the like, be actuated. On the carrier 22 itself, the current regulating elements 19, 21 are optionally arranged to be adjustable in the horizontal direction, so that the width of the vertically directed channels 20 is adjustable. Also, the number of current regulating elements 19, 21 can be varied. In principle, all current regulating elements 19, 21 are identical. In the first place, this applies to the power regulation elements 19 arranged freely in the receiving space 11. However, the power regulation elements 21 lying on the side walls 13, 14 are also identical to one another. Opposite the freely arranged in the receiving space 11 Stromregulierungselementen 19, the lying on the outer sides of the current regulating elements 21 are formed only split, so that they are adapted on the one hand to the side walls 13, 14 and on the other hand on the channels 20 side facing identical to the current regulating elements 19. In height, which essentially determines the shape and design of the channels 20, all current regulating elements 19, 21 have the same dimensions. Also, the distances between the current regulating elements 19, 21 are the same, so that the channels 20 are equal not only in height but also in width.

Zur Verstellung des Neigungswinkels α des Förderelementes 17 ist diesem ein Antrieb 25 zugeordnet, der bevorzugt als Spinelantrieb ausgebildet ist. Selbstverständlich sind andere Antriebe, auch manuelle Antriebseinrichtungen möglich. Optional kann das Förderelement 17 auch zusätzliche Antriebe zur Höhenverstellung aufweisen. Sämtliche Antriebe 23, 24, 25 sind an Steuerungen angeschlossen. Bevorzugt sind alle Antriebe 23 bis 25 mit einer gemeinsamen (nicht explizit dargestellten) Steuerung verbunden. Die Steuerung kann auch in Verbindung mit einem Messelement oder dergleichen in Wirkverbindung stehen. Beispielsweise kann ein Messelement zur Messung/Erkennung der Durchmesser der Produkte vorgesehen sein. In Abhängigkeit der Durchmesser der Produkte lassen sich dann die Antriebe 23 bis 25 zur Einstellung des Neigungswinkels α und/oder des Abstands zwischen Förderelement 17 und den Stromregulierungselementen 19, 21 steuern. Es besteht optional auch die Möglichkeit, dass der jeweilige Durchmesser der Produkte über ein Eingabefeld oder dergleichen z.B. an einem Bedienterminal vorgegeben bzw. eingegeben wird, um die Antriebe 23 bis 25 zu steuern.To adjust the inclination angle α of the conveying element 17, a drive 25 is associated with this, which is preferably designed as a spinel drive. Of course, other drives, including manual drive devices are possible. Optionally, the conveyor element 17 may also have additional drives for height adjustment. All drives 23, 24, 25 are connected to controls. Preferably, all drives 23 to 25 are connected to a common (not explicitly shown) control. The controller may also be operatively connected in conjunction with a measuring element or the like. For example, a measuring element for measuring / detecting the diameter of the products may be provided. Depending on the diameter of the products can then be the drives 23 to 25 for adjusting the inclination angle α and / or the distance between the conveying element 17 and the current regulating elements 19, 21 control. Optionally there is also the possibility that the respective diameter of the products may be transmitted via an input field or the like e.g. is specified or input to an operator terminal to control the drives 23 to 25.

Die Seitenwände 13, 14 sind - bezogen auf die Produkte bzw. die Produktgeometrie - vorzugsweise formatunabhängig und fest an einem Rahmen 26, Gehäuse oder dergleichen befestigt. Vorzugsweise die Vorderwand 15 ist als Sichtscheibe ausgebildet und formatabhängig. Zur Anpassung des Aufnahmeraums 11 an geänderte Produktlängen ist mindestens die Sichtscheibe verstellbar ausgebildet.The side walls 13, 14 are - based on the products or the product geometry - preferably format independent and fixed to a frame 26, housing or the like. Preferably, the front wall 15 is formed as a viewing window and format-dependent. To adapt the receiving space 11 to changed product lengths at least the lens is adjustable.

Wie bereits erwähnt, ist die Verstellbarkeit des Neigungswinkels α sowie des Abstands zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21 abhängig vom Durchmesser der Produkte und der Anzahl der Kanäle 20. Auch die Innenbreite der zu entleerenden Behälter kann ein Einstellparameter sein. Anders ausgedrückt können der Neigungswinkel α und der Abstand zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21 als eine Funktion von Durchmesser der Produkte und/oder Innenbreite der Behälter 12 abgebildet werden.As already mentioned, the adjustability of the inclination angle α and the distance between the conveying element 17 and the current regulating elements 19, 21 depends on the diameter of the products and the number of channels 20. The internal width of the containers to be emptied may also be an adjustment parameter. In other words, the angle of inclination α and the distance between the conveying element 17 and the flow regulating elements 19, 21 can be depicted as a function of the diameter of the products and / or the inner width of the containers 12.

Im Folgenden wird das Verfahrensprinzip anhand der Figuren näher erläutert: Ein mit Produkten gefüllter Behälter 12 wird manuell oder automatisch mit geeigneten Hilfsmitteln in üblicher Weise über Kopf in den Bereich eines Anschlussmittels des Entleermagazins 10 gebracht bzw. geschwenkt. Die Produkte fallen direkt oder nach dem Öffnen eines Schließelementes in den Aufnahmeraum 11 des Entleermagazins 10. Der aus den Produkten gebildete Produktstrom wird durch den Aufnahmeraum 11 und durch die Kanäle 20 dem Förderelement 17 zugeführt, das den Produktstrom durch den Kanal 18 aus dem Entleermagazin 10 transportiert. Beim Strömen der Produkte durch den Aufnahmeraum 11 wird der Produktstrom P (siehe z.B. Figur 2) im Bereich der Stromregulierungselemente 19, 21 in kleinere Produktströme PK (siehe z.B. Figur 2) geteilt. Anders ausgedrückt regulieren die Stromregulierungselemente 19,21 den einströmenden Produktstrom P, so dass dieser gleichmäßig in einzelne gleich große Produktströme PK auf die Kanäle 20 aufgeteilt und mit etwa gleichen Wegen nach den Stromregulierungselementen 19, 21 im Bereich des Kanals 18 wieder zu einem gemeinsamen Produktstrom PA (siehe Figur 2) zusammengeführt und abtransportiert wird. Die vertikal strömenden Produktströme PK werden durch das Förderelement 17 quasi umgelenkt und bilden jeweils einen entsprechend der Neigung des Förderelementes 17 geneigten Produktstrom PN. Die einzelnen Produktströme PN liegen übereinander und bilden den gemeinsamen Produktstrom PA. Die Breite der Produktströme PK sowie die Höhe der Produktströme PN ist jeweils gleich. Die Produktströme PN sind aus mindestens einer Lage von Produkten, vorzugsweise jedoch aus mehreren Produktlagen gebildet. Die Produktlagenhöhe des gemeinsamen Produktstroms PA, also die übereinander gestapelte Anzahl von Produkten bzw. Produktlagen, ist grundsätzlich durch die Anzahl der Kanäle 20 teilbar. Anders ausgedrückt ist der Abstand zwischen den Stromregulierungselementen 19, 21 und dem Förderelement 17 derart gewählt, dass jeder Produktstrom PN aus einer ganzzahligen Anzahl von Produktlagen besteht. Die Anzahl der Kanäle 20 hängt dabei insbesondere von der Breite der zu entleerenden Schragen ab. Je breiter ein Schragen ist, desto größer ist die Anzahl der Kanäle 20 und umgekehrt.In the following, the method principle is explained in more detail with reference to the figures: A container 12 filled with products is brought or pivoted manually or automatically with suitable aids in the usual way via the head into the region of a connection means of the emptying magazine 10. The products fall into the receiving space 11 of the emptying magazine 10 directly or after opening a closing element. The product stream formed from the products is supplied through the receiving space 11 and through the channels 20 to the conveying element 17, which delivers the product flow through the channel 18 from the emptying magazine 10 transported. When the products flow through the receiving space 11, the product flow P (see, for example, FIG FIG. 2 ) in the region of the current regulating elements 19, 21 into smaller product streams P K (see, for example, US Pat FIG. 2 ) divided. In other words, the current regulating elements 19, 21 regulate the inflowing product flow P so that it is evenly divided into individual equal product flows P K onto the channels 20 and returned to a common product flow with approximately equal paths to the flow regulating elements 19, 21 in the region of the channel 18 P A (see FIG. 2 ) is brought together and transported away. The vertically flowing product streams P K are virtually deflected by the conveying element 17 and each form a corresponding to the inclination of the conveying element 17 inclined product flow P N. The individual product streams P N lie above one another and form the common product stream P A. The width of the product streams P K and the height of the product streams P N are the same. The product streams P N are formed from at least one layer of products, but preferably from several product layers. The product layer height of the common product flow P A , ie the stacked number of products or product layers, is basically divisible by the number of channels 20. In other words, the distance between the current regulating elements 19, 21 and the Conveying element 17 is selected such that each product flow P N consists of an integer number of product layers. The number of channels 20 depends in particular on the width of the drawer to be emptied. The wider a Schragen, the greater the number of channels 20 and vice versa.

Der aus den einzelnen Produktströmen PK bzw. PN gebildete Produktstrom PA wird schräg nach unten abgeführt. Das heißt, dass alle einzelnen aus den Kanälen 20 strömenden Produktströme PK denselben Weg zurücklegen, bis sie auf das Förderelement 17 bzw. den darauf bereits befindlichen Produktstrom PN des stromaufwärts liegenden Kanals 20 oder der darauf befindlichen Produktströme PN der stromaufwärts liegenden Kanäle 20 treffen. Der Abstand zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21, genauer zwischen der Oberseite des Förderelementes 17 und den Unterkanten der Stromregulierungselemente 19, 21, wird in Abhängigkeit der Durchmesser der Produkte eingestellt. Der Produktstrom PA wird dann mit einem weiteren, beispielsweise von einer Produktionsmaschine ("Maker") stammenden Produktstrom PM zu einem Gesamtmassenstrom PG vereinigt (siehe z.B. Figur 3).The product flow P A formed from the individual product streams P K and P N is discharged obliquely downwards. This means that all the individual product streams P K flowing out of the channels 20 travel the same way until they reach the conveying element 17 or the product stream P N of the upstream channel 20 or the product streams P N of the upstream channels 20 thereupon to meet. The distance between the conveying element 17 and the current regulating elements 19, 21, more precisely between the top of the conveying element 17 and the lower edges of the current regulating elements 19, 21, is adjusted depending on the diameter of the products. The product stream P A is then combined with a further, for example from a production machine ("Maker") originating product flow P M to a total mass flow P G (see, eg FIG. 3 ).

Die Neigung bzw. der Neigungswinkel α und der Abstand zwischen dem Förderelement 17 und den Stromregulierungselementen 19,21 können unabhängig voneinander eingestellt werden. Vorzugsweise wird mittels der übergeordneten Steuerung aber eine direkte Beziehung zwischen diesen beiden Parametern hergestellt. Die Kanäle 20 sind derart ausgebildet, und zwar insbesondere durch Positionierung der Stromregulierungselemente 19, 21 horizontal zueinander, dass die Produktströme PK alle die gleiche Breite und beim Auftreffen auf das Förderelement 17 oder den bereits auf dem Förderelement 17 liegenden Produktstrom PK die gleiche Höhe aufweisen. Die Abstandseinstellung zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21 wird vorzugsweise dadurch erreicht, dass alle Stromregulierungselemente 19, 21 über einen gemeinsamen Träger 22 in der Höhe verstellt, also auf und ab bewegt werden. Die Verstellung der Höhe der Stromregulierungselemente 19, 21 und der Neigung des Förderelementes 17 erfolgt durch geeignete Antriebe 23, 24, 25. Vorzugsweise werden die Durchmesser der Produkte gemessen. Das Messergebnis wird über eine Steuerung an die Antriebe 23, 24, 25 weiter gegeben, so dass der Neigungswinkel α und/oder der Abstand zwischen dem Förderelement 17 und den Stromregulierungselementen 19, 21 entsprechend eingestellt wird. Die Durchmessergröße kann aber auch über geeignete Eingabefelder, Tasten oder dergleichen eingegeben und zur Steuerung verwendet werden.The inclination or the inclination angle α and the distance between the conveying element 17 and the current regulating elements 19, 21 can be adjusted independently of each other. Preferably, however, a direct relationship between these two parameters is established by means of the higher-level controller. The channels 20 are formed in such a way, in particular by positioning the Stromregulierungselemente 19, 21 horizontally to each other that the product streams P K all the same width and when hitting the conveyor element 17 or lying already on the conveyor element 17 product flow P K the same height exhibit. The distance adjustment between the conveying element 17 and the current regulating elements 19, 21 is preferably achieved in that all current regulating elements 19, 21 adjusted by a common carrier 22 in height, so be moved up and down. The adjustment of the height of the current regulating elements 19, 21 and the inclination of the conveying element 17 is effected by suitable drives 23, 24, 25. Preferably, the diameters of the products are measured. The measurement result is transmitted via a control to the drives 23, 24, 25 further given, so that the inclination angle α and / or the distance between the conveying element 17 and the current regulating elements 19, 21 is set accordingly. The diameter size can also be entered via suitable input fields, buttons or the like and used for control.

Für den Fall, dass ein Produktwechsel erfolgen soll, beispielsweise Produkte mit einem abweichenden Durchmesser, kann dies über die Steuerung, beispielsweise über einen Touch-Screen oder dergleichen vom Bediener eingegeben werden. Alternativ ist mittels Datenverbindung mit und von der Zigaretten- oder Filterstabherstellungsmaschine der Durchmesser übertragbar, um diesen Wert für die automatische Anpassung zu nutzen. Anschließend werden die Neigung und/oder der Abstand automatisch angepasst, so dass ein optimierter und gleichmäßiger Abfluss des Produktstroms gewährleistet ist.In the event that a product change should take place, for example products with a different diameter, this can be entered via the controller, for example via a touch screen or the like by the operator. Alternatively, the diameter can be transferred by data link to and from the cigarette or filter rod making machine to use this value for automatic adjustment. Subsequently, the inclination and / or the distance are adjusted automatically, so that an optimized and even outflow of the product flow is ensured.

Wie z.B. der Figur 3 zu entnehmen ist, strömt der Massenstrom PA aus dem Entleermagazin 10 über das Förderelement 17 in einen Mündungsbereich 27 des Kanals 18. Der Massenstrom PA wird durch den Mündungsbereich 27 geleitet und trifft in einem spitzen Winkel (spitzer Winkel bedeutet kleiner 90°) auf den unteren Massenstrom PM, der auf einem Förderelement 28 transportiert wird. Am Ausgang des Mündungsbereichs 27 treffen die Massenströme PA und PM aufeinander und vereinigen sich zu dem gemeinsamen Massenstrom PG, der vorzugsweise auf einem zusätzlichen Förderelement 29 abtransportiert wird. In der Tabak verarbeitenden Industrie haben sich insbesondere die Höhen 80mm, 100mm und 120mm für den abzutransportierenden Massenstrom PG durchgesetzt. Die beiden Förderelemente 28 und 29 können mit einem Leitblech 50 oder dergleichen miteinander verbunden sein. Genauer kann das Leitblech 50 oder ein entsprechendes Element, z.B. ein Brückenelement oder dergleichen, den Abstand zwischen den beiden Förderelementen 28, 29 überbrücken. Vorzugsweise ist der Bereich des Übergangs zwischen den beiden Förderelementen 28, 29 im Wesentlichen unterhalb des Mündungsbereichs 27 angeordnet. Mit anderen Worten ist das Leitblech 50 in einem Auftreffbereich der aus dem Mündungsbereich 27 strömenden Produkte angeordnet.Like the FIG. 3 can be seen, the mass flow P A flows from the discharge hopper 10 via the conveying element 17 in an orifice region 27 of the channel 18. The mass flow P A is passed through the mouth region 27 and hits at an acute angle (acute angle means less than 90 °) the lower mass flow P M , which is transported on a conveying element 28. At the outlet of the mouth region 27, the mass flows P A and P M meet and unite to the common mass flow P G , which is preferably transported away on an additional conveyor element 29. In the tobacco processing industry in particular the heights 80mm, 100mm and 120mm have prevailed for the mass flow P G to be removed. The two conveying elements 28 and 29 may be connected to one another with a guide plate 50 or the like. More precisely, the guide plate 50 or a corresponding element, for example a bridge element or the like, can bridge the distance between the two conveying elements 28, 29. Preferably, the region of the transition between the two conveying elements 28, 29 is arranged substantially below the mouth region 27. In other words, the baffle 50 is arranged in an impact area of the products flowing out of the mouth region 27.

Der Mündungsbereich 27 kann, wie in Figur 3 dargestellt, eine einfache Verlängerung des Kanals 18 sein, wobei die Verlängerung aus einem unteren Leitelement 30 und einem oberen Leitelement 31 gebildet ist. Die beiden Leitelemente 30, 31 sind gekrümmt ausgebildet. Das obere Leitelement 31 ist schwenkbar um einen Schwenkpunkt S ausgebildet. Im Falle eines flacheren Massenstroms PA oder zum Stoppen des Massenstroms PA fällt das obere Leitelement 31 nach unten. Genauer schwenkt das Leitelement 31 gegen den Uhrzeigersinn um den Schwenkpunkt S, um den Mündungsbereich 27 zu verengen. Sobald der Massenstrom PA wieder mit voller Höhe transportiert wird, drückt der Massenstrom PA das Leitelement 31 wieder in die geöffnete Stellung (wie in Figur 3 gezeigt).The mouth region 27 can, as in FIG. 3 shown, a simple extension of the channel 18, wherein the extension of a lower guide element 30 and an upper guide element 31 is formed. The two guide elements 30, 31 are curved. The upper guide element 31 is pivotally formed about a pivot point S. In the case of a flatter mass flow P A or to stop the mass flow P A , the upper guide element 31 falls down. More specifically, the guide member 31 pivots counterclockwise about the pivot point S to narrow the mouth portion 27. As soon as the mass flow P A is again transported at full height, the mass flow P A pushes the guide element 31 back into the open position (as in FIG FIG. 3 shown).

Im Mündungsbereich 27 kann jedoch auch eine Einrichtung 32 gemäß der Figuren 4 bis 6 angeordnet sein. Die Einrichtung 32 kann integraler Bestandteil des Entleermagazins 10 sein, alternativ aber auch als eigenständige Einrichtung 32 zum Zusammenführen beliebiger Massenströme eingesetzt werden. Die Einrichtung 32 umfasst ein erstes Leitelement 33 und ein oberhalb des ersten Leitelementes 33 angeordnetes, zweites Leitelement 34. Beide Leitelemente 33, 34 bilden einen Mündungskanal 35 zum Zusammenführen des aus dem Mündungskanal 35 strömenden Massenstroms PA mit einem weiteren, in einem spitzen Winkel auf den Massenstrom PA treffenden Massenstrom PM. Das obere Leitelement 34 ist als Begrenzungselement 36 zum Regeln des aus dem Mündungskanal 35 strömenden Massenstroms PA und zur Bildung eines Ausgleichsreservoirs ausgebildet. Zum Regeln des Massenstroms PA ist das Begrenzungselement 36 bewegbar ausgebildet. In der bevorzugten Ausführungsform ist das Begrenzungselement 36 schwenkbar, beispielsweise an einer Seitenwand, einem Gestell oder Rahmen oder dergleichen angeordnet. Durch die Schwenkbarkeit des Begrenzungselementes 36 ist der Abstand zwischen dem unteren Leitelement 33, das z.B. ein einfaches gebogenes Blech 37, ein angetriebener Förderer oder dergleichen sein kann, zur Vergrößerung oder Verkleinerung des Mündungskanals 35 veränderbar. Durch die Schwenkbarkeit des Begrenzungselementes 36 ist dieser auch als Ausgleichsreservoir geeignet. Mit der Auslenkung, also insbesondere der Vergrößerung des Mündungskanals 35 vergrößert sich auch das Aufnahme- bzw. Speichervolumen im Bereich des Mündungskanals 35. Andere Ausbildungen des Begrenzungselementes 36 zur Schaffung eines Ausgleichsreservoirs, wie z.B. ein flexibles Bandelement oder dergleichen, sind aber ebenfalls möglich.In the mouth region 27, however, a device 32 according to the FIGS. 4 to 6 be arranged. The device 32 may be an integral part of the emptying magazine 10, but alternatively be used as an independent device 32 for merging any mass flows. The device 32 comprises a first guide element 33 and a second guide element 34 arranged above the first guide element 33. Both guide elements 33, 34 form an outlet channel 35 for merging the mass flow P A flowing from the outlet channel 35 with another, at an acute angle the mass flow P A striking mass flow P M. The upper guide element 34 is designed as a delimiting element 36 for regulating the mass flow P A flowing out of the outlet channel 35 and for forming a compensation reservoir. For controlling the mass flow P A , the limiting element 36 is designed to be movable. In the preferred embodiment, the restriction member 36 is pivotally mounted, for example, on a side wall, a frame or frame or the like. Due to the pivoting of the limiting element 36, the distance between the lower guide element 33, which may be, for example, a simple bent plate 37, a driven conveyor or the like, to increase or decrease the mouth channel 35 is variable. Due to the pivoting of the limiting element 36, this is also suitable as a compensation reservoir. With the deflection, ie in particular the enlargement of the mouth channel 35, the receiving or storage volume in the region of the mouth channel 35 increases. Other embodiments of the limiting element 36 to create a compensation reservoir, such as a flexible band member or the like, but also possible.

Wie bereits erwähnt, ist das Begrenzungselement 36 schwenkbar angeordnet, und zwar in einem Schwenkpunkt S. Dazu ist das Begrenzungselement 36 einem Pendelarm 38 zugeordnet. Genauer bilden Begrenzungselement 36 und Pendelarm 38 eine vorzugsweise voneinander lösbare Einheit, die um den Schwenkpunkt S schwenkbar ist. Der Pendelarm 38 selbst kann als Betätigungsmechanismus für die Schwenkbewegung dienen. Vorzugsweise ist dem Pendelarm 38 jedoch ein zusätzlicher Betätigungsmechanismus zugeordnet. Dazu ist dem Pendelarm 38 an einem freien Ende 39 ein Gewicht 40 zugeordnet. Andere Betätigungsmechanismen, wie z.B. Stellmotore oder dergleichen sind aber ebenfalls einsetzbar. Das Gewicht 40 ist austauschbar und insbesondere auch an unterschiedlichen Positionen des Pendelarms 38, der einen Hebelarm um den Schwenkpunkt S bildet, zu befestigen, um den Schwerpunkt des Gewichts 40 zu verlagern. Optional kann dem Pendelarm 38 ein Positionsgeber 51 zugeordnet sein, der beispielsweise aus einem Auslöseelement 52 und mindestens einem, vorzugsweise jedoch mehreren und besonders bevorzugt drei Näherungsinitiatoren 53, Sensoren oder dergleichen besteht. Die Position des Auslöseelementes 52 kann zur Steuerung z.B. der Fördergeschwindigkeiten des Förderelementes 17 und/oder des Förderelementes 28 und/oder des Förderelementes 29 dienen. In der Figur 4 sind alle Näherungsinitiatoren 53 durch das Auslöseelement 52 abgedeckt, was z.B. bedeuten kann, dass der Mündungskanal 35 maximal geöffnet ist. In der Figur 5 sind alle Näherungsinitiatoren 53 frei, was bedeuten kann, dass der Mündungskanal 35 geschlossen ist. Andere Positionen des Auslöseelementes 52 definieren damit eine geänderte Öffnung des Mündungskanals 35.As already mentioned, the limiting element 36 is pivotably arranged, specifically in a pivot point S. For this purpose, the limiting element 36 is associated with a pendulum arm 38. More specifically, the limiting element 36 and the pendulum arm 38 form a preferably detachable unit, which is pivotable about the pivot point S. The pendulum arm 38 itself can serve as an actuating mechanism for the pivoting movement. Preferably, however, the pendulum arm 38 is associated with an additional actuating mechanism. For this purpose, the pendulum arm 38 is assigned a weight 40 at a free end 39. Other actuating mechanisms, such as servo motors or the like are also used. The weight 40 is replaceable and in particular also at different positions of the pendulum arm 38, which forms a lever arm about the pivot point S, to fix the center of gravity of the weight 40 to move. Optionally, the pendulum arm 38 may be associated with a position sensor 51, which consists for example of a trigger element 52 and at least one, but preferably more and more preferably three proximity sensors 53, sensors or the like. The position of the triggering element 52 can serve to control, for example, the conveying speeds of the conveying element 17 and / or of the conveying element 28 and / or of the conveying element 29. In the FIG. 4 are all proximity switches 53 covered by the trigger element 52, which may mean, for example, that the mouth channel 35 is open to the maximum. In the FIG. 5 are all proximity switches 53 free, which may mean that the mouth channel 35 is closed. Other positions of the trigger element 52 thus define a modified opening of the mouth channel 35.

An dem freien Ende 41 vom Begrenzungselement 36, also an dem dem Schwenkpunkt S gegenüber liegenden Ende ist ein Sperrelement 42 angeordnet. Das Sperrelement 42 ist schwenkbar am Begrenzungselement 36 angeordnet und ist vorzugsweise als einfaches Klappelement oder dergleichen ausgebildet. Genauer ist das Sperrelement 42 schwenkbar an einem Rahmen 43 gelagert, der am freien Ende 41 angeordnet ist. Das Sperrelement 42, das ein einfaches Blech, ein blockartiges Element oder dergleichen sein kann, ist durch eine Ausnehmung 44 in dem Begrenzungselement 36 aus der den Mündungskanal 35 freigebenden Position in eine den Mündungskanal 35 schließende Position und umgekehrt schwenkbar (siehe hierzu insbesondere Figuren 6 und 7). Das Sperrelement 42 weist zwei Abschnitte 55, 56 auf. Einer der Abschnitte 55, 56, beispielsweise der Abschnitt 56, ragt, zumindest in einer Schließstellung, in den Mündungskanal 35, während der andere Abschnitt 55 stets, also unabhängig von der Schwenkposition, außerhalb des Mündungskanals 35 liegt.At the free end 41 of the limiting element 36, ie at the pivot point S opposite end, a blocking element 42 is arranged. The locking element 42 is pivotally mounted on the limiting element 36 and is preferably designed as a simple folding element or the like. More specifically, the locking member 42 is pivotally mounted on a frame 43 which is disposed at the free end 41. The blocking element 42, which may be a simple plate, a block-like element or the like, is pivotable through a recess 44 in the limiting element 36 from the mouth channel 35 releasing position into a mouth channel 35 closing position and vice versa (see in particular FIGS. 6 and 7 ). The blocking element 42 has two sections 55, 56. One of the sections 55, 56, For example, the portion 56, projects, at least in a closed position, in the mouth channel 35, while the other portion 55 is always, so regardless of the pivot position, outside the mouth channel 35.

An dem zweiten, stets außerhalb des Mündungskanals 35 befindlichen Abschnitt 55 ist ein Betätigungselement 45 angeordnet. Das Betätigungselement 45 ist vorzugsweise einstellbar. In der gezeigten Ausführungsform ist das Betätigungselement 45 ein veränderbares Gewicht, das z.B. aus mit einer Schraube fixierten Unterlegscheiben gebildet ist. Das Betätigungselement 45 kann auch eine Rändelschraube sein, deren Abstand zum Sperrelement 42 veränderbar ist. Auch kann der Abstand zur Schwenkachse AS optional variiert bzw. eingestellt werden. Selbstverständlich sind andere Betätigungselemente 45, wie z.B. einfache Muttern, Gewichte, Federelemente, Stellglieder oder dergleichen einsetzbar.At the second, always located outside of the mouth channel 35 section 55, an actuating element 45 is arranged. The actuating element 45 is preferably adjustable. In the embodiment shown, the actuating element 45 is a variable weight, which is formed, for example, from washers fixed with a screw. The actuating element 45 may also be a knurled screw whose distance from the blocking element 42 is variable. Also, the distance to the pivot axis A S can optionally be varied or adjusted. Of course, other actuators 45, such as simple nuts, weights, spring elements, actuators or the like can be used.

Ebenfalls im Bereich des freien Endes 41, vorzugsweise an dem Rahmen 43 ist ein Bandelement 46 oder ähnliches angelenkt. Das Bandelement 46 ist über mindestens zwei, vorzugsweise jedoch drei Umlenkrollen 47 geführt und an dem dem Befestigungselement 36 entgegen gesetzten Ende mit einem Gewicht 48 versehen. Das Gewicht 48 wird je nach Stellung des Sperrelementes 42 nach oben oder nach unten, bedingt durch die Verbindung mit dem Bandelement 46, gezogen. In geöffneter Position des Sperrelementes 42 ist das Gewicht 48 in einer unteren Position (siehe Figur 4), während sich das Gewicht 48 in Schließposition des Sperrelementes 42 in oberer Position befindet (siehe Figur 5).Also in the region of the free end 41, preferably on the frame 43, a band member 46 or the like is articulated. The band member 46 is guided over at least two, but preferably three deflection rollers 47 and provided at the fastening element 36 opposite end with a weight 48. The weight 48 is depending on the position of the locking element 42 up or down, due to the connection with the band member 46 is pulled. In the open position of the blocking element 42, the weight 48 is in a lower position (see FIG. 4 ), while the weight 48 is in the closed position of the locking element 42 in the upper position (see FIG. 5 ).

Die Funktionsweise der Einrichtung 32 wird im Folgenden anhand der Zusammenführung des aus dem Entleermagazin 10 strömenden Massenstroms PA mit dem aus einer Herstellungsmaschine strömenden Massenstrom PM beschrieben: Üblicherweise strömt der Massenstrom PA durch den Kanal 18 und drückt das Begrenzungselement 36 auf, so dass der Mündungskanal 35 geöffnet ist. Mit anderen Worten wird der Pendelarm 38 mit dem Begrenzungselement 36 in eine geöffnete Stellung geschwenkt. Der Massenstrom PA strömt durch den Mündungskanal 35, der den Massenstrom 35 schräg nach unten in einem spitzen Winkel auf den Massenstrom PM lenkt. Im Mündungsbereich 27 vereinigen sich die beiden Massenströme PA und PM zu dem Massenstrom PG. Beim Schwenken des Begrenzungselementes 36 im Uhrzeigersinn um den Schwenkpunkt S wird das an dem Begrenzungselement 36 befestigte Sperrelement 42 mitgenommen. Sobald der Schwerpunkt des Betätigungselementes 45 den Scheitelpunkt überschritten hat, kippt das Sperrelement 42 mit dem Abschnitt 55 in Richtung des Begrenzungselementes 36. Der Mündungskanal 35 ist damit vollständig geöffnet (siehe insbesondere Figur 4).The mode of operation of the device 32 will be described below on the basis of the merging of the mass flow P A flowing from the emptying magazine 10 with the mass flow P M flowing from a production machine. Usually, the mass flow P A flows through the channel 18 and presses the limiting element 36 so that the mouth channel 35 is open. In other words, the pendulum arm 38 is pivoted with the limiting element 36 in an open position. The mass flow P A flows through the orifice passage 35, which directs the mass flow 35 obliquely downward at an acute angle to the mass flow P M. In the mouth region 27, the two mass flows P A and P M unite to the mass flow P G. When the limiting element 36 is pivoted clockwise about the pivot point S, the blocking element 42 fastened to the limiting element 36 is entrained. As soon as the center of gravity of the actuating element 45 has exceeded the vertex, the blocking element 42 tilts with the section 55 in the direction of the limiting element 36. The mouth channel 35 is thus completely open (see in particular FIG FIG. 4 ).

Für den Fall, dass der Massenstrom PA reduziert oder ganz angehalten wird oder angehalten werden soll, schwenkt das Begrenzungselement 36 vorzugsweise mittels Schwerkraft gegen den Massenstrom PA. Dies führt zu einer Verengung des Mündungskanals 35, so dass sich in der Engstelle eine Art Produkt-Pfropf bildet, der den Mündungskanal 35 sperrt. Dadurch entsteht im Mündungsbereich 27 ein Freiraum, also ein von Produkten freier Raum. Sobald der Schwerpunkt des Betätigungselementes 45 beim Schwenken des Betätigungselementes 36 um die Schwenkachse S gegen den Uhrzeigersinn den Scheitelpunkt überschritten hat, kippt das Sperrelement 42 mit dem Abschnitt 56 in den Mündungskanal 35. Anders ausgedrückt klappt das Sperrelement 42 mit dem Abschnitt 55 vom Begrenzungselement 36 weg, so dass der Mündungskanal 35 vollständig geschlossen ist (siehe Figuren 5 bis 7). Der möglicherweise verbleibende Abstand zwischen dem Sperrelement 42 und dem Leitelement 33 ist vorzugsweise geringer als der Durchmesser der zu fördernden Produkte. Damit wird auch das vereinzelte Nachlaufen bzw. Herausfallen von Produkten aus dem Massenstrom PA wirksam verhindert. Der Massenstrom PA kann durch die Einrichtung 32 also exakt geführt und geregelt werden.In the event that the mass flow P A is reduced or stopped completely or should be stopped, the limiting element 36 pivots preferably by gravity against the mass flow P A. This leads to a narrowing of the mouth channel 35, so that forms a kind of product graft in the bottleneck, which blocks the mouth channel 35. This creates a free space in the mouth region 27, that is, a space free of products. As soon as the center of gravity of the actuating element 45 has exceeded the vertex when pivoting the actuating element 36 about the pivot axis S in the counterclockwise direction, the blocking element 42 tilts with the section 56 into the mouth channel 35. In other words, the blocking element 42 works with the section 55 away from the limiting element 36 , so that the mouth channel 35 is completely closed (see FIGS. 5 to 7 ). The possibly remaining distance between the blocking element 42 and the guide element 33 is preferably smaller than the diameter of the products to be conveyed. This also the occasional lagging or falling out of products from the mass flow P A is effectively prevented. The mass flow P A can thus be exactly guided and regulated by the device 32.

In anderen Ausführungen können das Begrenzungselement 36 und/oder das Sperrelement 42 aktiv gesteuert, nämlich bewegt bzw. geschwenkt werden. Die Steuerung der Einrichtung 32 kann über eine eigene Steuerung, aber auch über ein Steuerung vorgeordneter oder nachgeordneter Vorrichtungen oder Maschinen erfolgen.In other embodiments, the limiting element 36 and / or the blocking element 42 can be actively controlled, namely moved or pivoted. The control of the device 32 can be done via its own control, but also via a control of upstream or downstream devices or machines.
