An Independent claim for a container emptying device is also included.

Description

Die Erfindung betrifft ein Verfahren zum aufeinanderfolgenden Entleeren von Artikel enthaltenden Behältern (Vollbehältern), die an einer Aufgabestation in einen Rahmen überführt, danach mit dem Rahmen zu einer Entleerungsstation bewegt und dort entleert werden, wonach sie mit dem Rahmen zu der Aufgabestation zurückbewegt werden.
Die Erfindung betrifft außerdem eine Vorrichtung zum aufeinanderfolgenden Entleeren von Artikel enthaltenden Behältern (Vollbehältern), mit einer Überführungsvor richtung zum Überführen eines zugeförderten Vollbehälters an einer Aufgabestation in einen Rahmen, einer Fördervorrichtung zum Bewegen von Rahmen und Vollbehälter zu einer Entleerungsstation und einer Fördervorrichtung zum Zurückbewegen des Rahmens mit dem entleerten Behälter zu der Aufgabestation.The invention relates to a method for the successive emptying of containers containing containers (full containers), which are transferred to a loading station in a frame, then moved with the frame to a discharge station and emptied there, after which they are moved back with the frame to the loading station.
The invention also relates to a device for the successive emptying of containers containing containers (full containers), with a Überführvor direction for transferring a full container zugeförderten at a loading station in a frame, a conveyor for moving frame and full container to a discharge station and a conveyor for moving back the Frame with the empty container to the loading station.

Bei der Produktion von Artikeln, zum Beispiel von stabförmigen Artikeln der tabakverarbeitenden Industrie wie Zigaretten oder Filterstäben, werden diese oft in Behälter abgefüllt und in diesen zur Speicherung und/oder Weiterverarbeitung, insbesondere zur Verpackung gefördert. Bei der automatischen Zufuhr von in Behälter gefüllten Zigaretten zu den Magazinen von Packmaschinen oder zu Zwischenmagazinen, aus denen die Zigaretten auf Förderbändern zu den eigentlichen Packmaschinen im sogenannten Massenstrom gefördert werden, müssen die Behälter entleert werden. Bei den Behältern für Zigaretten handelt es sich im allgemeinen um sogenannte Schragen, die zumeist aus einer die Zigaretten in Form von Stapeln aufnehmenden Bodenfläche, zwei parallel zu den Zigarettenachsen verlaufenden Seitenwänden und einer senkrecht zu den Zigarettenachsen verlaufenden Rückwand bestehen; nach oben und vom sind die Schragen meist offen, doch können auch dort Wände vorgesehen sein, die zum Füllen und Entleeren entfernbar sind.In the production of articles, for example of rod-shaped articles of the tobacco processing industry such as cigarettes or filter rods, these are often filled into containers and promoted in these for storage and / or further processing, in particular for packaging. In the automatic supply of cigarettes filled in containers to the magazines of packaging machines or intermediate magazines, from which the cigarettes are conveyed on conveyor belts to the actual packaging machines in the so-called mass flow, the containers must be emptied. The containers for cigarettes are generally so-called Schragen, which consist mostly of a cigarettes in the form of stacks receiving bottom surface, two parallel to the cigarette axes extending side walls and a perpendicular to the cigarette axes rear wall; Upwards and downwards, the casings are usually open, but walls can also be provided there, which can be removed for filling and emptying.

Zum Entleeren der Artikel in die Magazine oder Zwischenmagazine werden die Behälter gedreht oder geschwenkt, damit die Artikel herausfallen können. Entsprechende Vorrichtungen sind bekannt. Die US-Patentschriften 3 655 080, 4 403 908, 3 527 369, 3 777 911 sowie die deutsche Patentschrift 19 39 395 beschreiben Dreh- und Schwenkanordnungen mit Aufnahmen oder Rahmen für mit Zigaretten gefüllte Behälter/Schragen. Dabei müssen die vollen Behälter zunächst in die Rahmen (Aufnahmen) überführt werden, worauf diese zur Entleerung geschwenkt oder gedreht werden. Nach dem Zurückschwenken oder Zurückdrehen werden die leeren Behälter aus den Rahmen entfernt und volle Behälter zugeführt. Hierzu sind besondere Mittel erforderlich. Außerdem erfordert das Entleeren Zeit, die bei den enormen Produktionsleistungen moderner Zigarettenmaschinen knapp ist.To empty the items in the magazines or intermediate magazines, the containers are rotated or pivoted so that the items can fall out. Corresponding devices are known. US Pat. Nos. 3,655,080, 4,403,908, 3,527,369, 3,777,911 and German Patent Specification 19 39 395 describe rotary and pivoting arrangements with receptacles or frames for containers / cassettes filled with cigarettes. The full container must first be transferred to the frame (recordings), whereupon they are pivoted or rotated for emptying. After swinging back or turning back the empty containers are removed from the frame and fed full containers. For this purpose, special funds are required. In addition, emptying requires time, which is scarce with the enormous production capacities of modern cigarette machines.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, das Beladen und Entladen der Aufnahmen mit vollen bzw. von leeren Behältern zu erleichtern und damit zu beschleunigen.
Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß ein weiterer Vollbehälter beim Überführen in den Rahmen den darin befindlichen leeren Behälter (Leerbehälter) unmittelbar oder mittelbar aus dem Rahmen entfernt.
In einer vorteilhaften Weiterbildung der Erfindung kann die Zufuhr eines Vollbehälters zu dem Rahmen mittels mindestens eines vorzugsweise horizontalen Förderbandes erfolgen, auf dem eine Mehrzahl von Vollbehältern gespeichert werden kann. Das Förderband oder besser zwei Förderbänder überführt dann den Vollbehälter in den Rahmen, wobei gleichzeitig ein in dem Rahmen befindlicher Leerbehälter aus dem Rahmen in einer Richtung entfernt wird, die die Fortsetzung der Zufuhrrichtung darstellt, d. h. der neue Vollbehälter wird durch die freie Vorderfläche des Rahmens diesem zugefördert, während der Leerbehälter aus dem Rahmen durch dessen Rückseite entfernt wird. Dabei kann ein voller Behälter einen Leerbehälter unmittelbar, also durch mechanischen Kontakt, aus dem Rahmen schieben.The problem underlying the invention is to facilitate the loading and unloading of the images with full or empty containers and thus to accelerate.
According to the invention, this object is achieved in that another full container when transferred to the frame located therein empty container (empty container) directly or indirectly removed from the frame.
In an advantageous embodiment of the invention, the supply of a full container to the frame by means of at least one preferably horizontal conveyor belt carried on which a plurality of full containers can be stored. The conveyor belt or better two conveyor belts then transfers the full container into the frame, at the same time removing an empty container in the frame from the frame in a direction that represents the continuation of the feed direction, ie the new full container is replaced by the free front surface of the frame fed while the empty container is removed from the frame through the back. In this case, a full container an empty container directly, ie by mechanical contact, push out of the frame.

Es ist aber auch möglich, einen Leerbehälter mittelbar, zum Beispiels mittels einer den Vollbehälter zu- und überführenden Aufnahme, aus dem Rahmen entfernen zu lassen.
Transportfähige Behälter für Zigaretten, auch Schragen genannt, sind meist quaderförmig geformt und bestehen im allgemeinen aus einem Boden, auf dem die Zigaretten quer zur Bodenstreckung liegen, aus zwei rechtwinklig dazu angeordneten vertikalen Seitenwände und aus einer Rückwand, die an die Seitenwände und den Boden angrenzt. Die Rückwand ist die größte Fläche und ist meist rechteckförmig geformt. Die Vorderwand eines Schragens fehlt, meist auch die Deckenwand. Ein Rahmen, mit dem die Erfindung zu realisieren ist, kann Seitenwände, Klemmvorrichtungen für den Schragen/Behälter sowie eine entfernbare Deckenwand, also einen Deckel aufweisen. Die Klemmvorrichtung dient zur sicheren Halterung des Schragens während einer Rahmenbewegung. Eine Vorderwand und eine Rückwand fehlt bei dem Rahmen, so daß ein durch die leere Vorderfläche zugeführter Vollbehälter einen in dem Rahmen befindlichen Leerbehälter durch die leere Rückfläche entfernen kann. Der Rahmen wird vorteilhaft mit dem Vollbehälter, evtl. nach einer Hubbewegung, mittels einer Schwenkbewegung zu der Entleerungsstation bewegt.
Gemäß einer weiteren wichtigen Ausgestaltung der Erfindung, der selbständiger erfinderischer Rang zukommt, wird der Rahmen mit dem Vollbehälter auf die oberen Enden von bewegbaren Wänden eines Magazins für die Artikel aufgesetzt. Darauf werden die Wände mit dem Rahmen und dem Vollbehälter nach unten bewegt, bis die Unterseite des Rahmens zumindest annähernd die Oberfläche der zwischen den auf- und abbewegbaren Wänden befindlichen Artikel erreicht. Danach wird ein Deckel des Rahmens entfernt, so daß die Artikel nach unten auf die Oberfläche sinken; danach werden die Wände mit dem Rahmen und dem Vollbehälter nach oben bewegt. Nach Erreichen einer oberen Position und Entleerung des Behälters wird der Rahmen mit dem nunmehr leeren Behälter mittels einer umgekehrten Schwenkbewegung zurück zur Aufgabestation bewegt. Nach dem Zurückschwenken des Rahmens sinken die Artikel zwischen den sich in ihrer oberen Position befindlichen Wänden ab, bis nach der erneuten Zufuhr des Rahmens mit einem neuen Vollbehälter ein den Wänden zugeordneter Sensor beim Erreichen der Artikeloberfläche durch die abwärtsgeführten oberen Enden der abgesenkten Wände ein Signal für das Entfernen des Deckels von dem Rahmen abgibt. Durch diese vorteilhafte Weiterbildung der Erfindung kann die Zeit, die vom Aufsetzen eines Rahmens auf dem oberen Ende der Wände bis zum Auslösen eines Rückschwenkvorganges minimiert werden, was der Erhöhung der Leistungsfähigkeit des Entleerungsverfahrens und der Entleerungsvorrichtung zugute kommt. Außerdem ist die Fallhöhe der aus dem Vollbehälter nach unten fallenden Artikel gering, so daß auch die bei höheren Fallhöhen erhöhte Störungsgefahr infolge sich querlegender Artikel gering ist.
Gemäß einer weiteren Ausführungsform der Erfindung kann ein Leerbehälter nach dem Zurückbewegen in die Aufgabestation in dem Rahmen durch Lösen der Klemmung freigegeben und von einem folgenden Vollbehälter auf eine Abgabefläche entfernt werden, von der er zu vorzugsweise zumindest annähernd horizontalen Abförderbändern abgesenkt wird.
Der Leerbehälter kann in der einfachsten Form durch direkten Kontakt mit einem Vollbehälter, der zum Beispiel von etwa horizontalen Förderbändern zugefördert wird, aus dem Rahmen entfernt werden. Zur Erhöhung der Zufördergeschwindigkeit und damit des Leistungsvermögens des Entleerungsverfahrens und der Vorrichtung kann in weiterer vorteilhafter Ausgestaltung der Erfindung, der selbständiger erfinderischer Rang zukommt, ein Vollbehälter von einem Antrieb, vorzugsweise von einem Linearantrieb, in einer Aufnahme zu der Aufgabestation gefördert und in den Rahmen überführt werden, wobei die Aufnahme den in dem Rahmen befindlichen Leerschragen entfernt. Eine einen Vollbehälter sehr schnell zufördernde Aufnahme kann dann zusätzlich den Leerbehälter (mittelbar) aus dem Rahmen entfernen.But it is also possible to have an empty container indirectly, for example, by means of a full container to the incoming and transferring recording to remove from the frame.
Transportable containers for cigarettes, also called Schragen, are generally cuboid shaped and generally consist of a bottom on which the cigarettes are transverse to the bottom extension, of two perpendicularly arranged vertical side walls and a rear wall adjacent to the side walls and the bottom , The back wall is the largest surface and is usually rectangular in shape. The front wall of a Schragen is missing, usually the ceiling wall. A framework with which the invention is to be realized, may have side walls, clamps for the tray / container and a removable ceiling wall, so a lid. The clamping device is used for secure support of the tray during a frame movement. A front wall and a rear wall are missing from the frame, so that a full container fed by the empty front surface can remove an empty container in the frame through the empty rear surface. The frame is advantageously moved with the full container, possibly after a lifting movement, by means of a pivoting movement to the emptying station.
According to another important embodiment of the invention, the independent inventive rank plays, the frame is placed with the full container on the upper ends of movable walls of a magazine for the article. Then the walls with the frame and the full container are moved downwards until the underside of the frame at least approximately reaches the surface of the articles located between the upwardly and downwardly movable walls. Thereafter, a lid of the frame is removed, so that the articles sink down to the surface; then the walls with the frame and the full container are moved upwards. After reaching an upper position and emptying of the container frame with the now empty container by means of a reversed pivoting movement moved back to the loading station. After swinging back of the frame, the articles sink between the walls in their upper position until after re-feeding the frame with a new full container a sensor associated with the walls upon reaching the article surface by the downwardly guided upper ends of the lowered walls a signal for removing the lid from the frame. By means of this advantageous development of the invention, the time taken by placing a frame on the upper end of the walls until a return pivoting operation is triggered can be improved, which increases the efficiency of the emptying method and the emptying device. In addition, the drop height of the falling down from the full container items is low, so that even at higher heights increased risk of failure due to querlegender article is low.
According to a further embodiment of the invention, after returning to the feeding station in the frame an empty container can be released by releasing the clamping and removed from a following full container onto a delivery surface, from which it is lowered to preferably at least approximately horizontal delivery belts.
The empty container can be removed in the simplest form by direct contact with a full container, which is conveyed for example by about horizontal conveyor belts, from the frame. To increase the Zufördergeschwindigkeit and thus the performance of the emptying process and the device can in a further advantageous embodiment of the invention, the independent inventive rank plays a solid container from a drive, preferably from a linear drive, promoted in a recording to the Aufzufestation and transferred into the frame be removed, wherein the receptacle located in the frame Leerschragen. A very fast zufördernde a full container recording can then also remove the empty container (indirectly) from the frame.

Das Verfahren gemäß der Erfindung eignet sich insbesondere für die Entleerung von Behältern, sogenannten Schragen, die mit auf Zigarettenproduktionsmaschinen hergestellten Zigaretten mit und ohne Filter gefüllt sind, und die zur Weiterverarbeitung, zum Beispiel auf Packmaschinen, gefördert werden.

Figur 1 zeigt die Seitenansicht einer Entleerungsvorrichtung 1 für mit Filterzigaretten 2 gefüllte Behälter/Schragen 3, die, wie Figur 2 erkennen läßt, einen horizontalen Boden 4, zwei vertikale Seitenwände 6 und eine vertikale Rückwand 7 aufweist. Die Vorderfläche 8 sowie die Deckenfläche 9 sind frei. Die Zigaretten 2 liegen neben- und übereinander in dem Behälter 3, wobei ihre Längsachsen parallel zu den Ebenen der Seitenwände verlaufen. Die Füllung der Behälter 3 mit Zigaretten 2 erfolgt meist im Anschluß an die Zigarettenherstellung auf Zigarettenproduktionsmaschinen durch spezielle Maschinen, sogenannte Schragenfüllmaschinen. Die mit Zigaretten gefüllten Behälter (im folgenden "Vollbehälter" genannt) werden - evtl. nach kürzerer oder längerer Lagerung - einer Vollschragenstation 11 der Entleerungsvorrichtung zugeführt, wobei sie auf parallelen Zuförderbändem 12 in Richtung des Pfeils 13 einem Rahmen (Kassette) 14 einer Schwenkeinrichtung 16 zugefördert und in einer Aufgabestation 17 in den Rahmen überführt werden. Die Schwenkeinrichtung 16 schwenkt den Rahmen 14 mit einem Vollbehälter 3 entsprechend dem Pfeil 18 zu einer Entleerungsstation 19 über einem Behälter in Form eines Magazins 21 einer sonst nicht dargestellten an sich bekannten Packmaschine für die Zigaretten 2, die in das Magazin entleert werden, worauf die Schwenkeinrichtung 16 den Rahmen 14 mit dem nun leeren Behälter 22 (im folgenden "Leerbehälter" genannte) entsprechend dem Pfeil 23 zu der Aufgabestation 17 zurückbewegt. Von einem der Aufgabestgation neu zugeführten Vollbehälter 3 wird ein Leerbehälter 22 aus dem Rahmen 14 entfernt und von einer Absenkvorrichtung 24 zunächst abgesenkt, worauf er dann auf parallelen Abförderbändern 26 zu einer Leerbehälterstation 28 entsprechend Pfeil 27 abgefördert wird.Figure 1 shows the side view of an emptying device 1 for filled with filter cigarettes 2 container / tray 3, which, as Figure 2 reveals, a horizontal bottom 4, two vertical side walls 6 and a vertical rear wall 7 has. The front surface 8 and the ceiling surface 9 are free. The cigarettes 2 are adjacent and one above the other in the container 3, with their longitudinal axes parallel to the planes of the side walls. The filling of the container 3 with cigarettes 2 is usually carried out following cigarette production on cigarette production machines by special machines, so-called Schragenfüllmaschinen. The filled with cigarettes container (hereinafter referred to as "full container") - possibly after a shorter or longer storage - a full rack station 11 of the emptying device supplied, wherein they on parallel Zuförderbändem 12 in the direction of arrow 13 a frame (cassette) 14 a pivoting device sixteenth be conveyed and transferred in a feeding station 17 in the frame. The pivoting device 16 pivots the frame 14 with a full container 3 according to the arrow 18 to a discharge station 19 on a container in the form of a magazine 21 an otherwise not shown packing machine for the cigarettes 2, which are emptied into the magazine, after which the pivoting device 16 the frame 14 with the now empty container 22 (hereinafter referred to as "empty container") moved back according to the arrow 23 to the loading station 17. An empty container 22 is removed from the frame 14 and initially lowered by a lowering device 24, whereupon it is then conveyed away on parallel delivery belts 26 to an empty container station 28 in accordance with arrow 27.

Nach der Beschreibung der Hauptbauelemente der Entleerungsvorrichtung 1 wird im folgenden auf Einzelheiten eingegangen.
Die Zuförderbänder 12 sind über Rollen 31, 32, 33 und 34 geführt, von denen Rolle 34 über einen Zahnriemen 36 von einem steuerbaren Elektromotor 37 und einem Getriebe 38 angetrieben ist. Auch die über Rollen 39 , 41, 42 und 43 geführten Abförderbänder 26 sind von dem Elektromotor 37 und seinem Getriebe 38 angetrieben. An der Aufgabestation 17 befindet sich der Rahmen 14, der, wie insbesondere Figur 2 zeigt, Seitenwände 47, 48 und einen Deckel 51 aufweist. Der Deckel 51 ist von einem besonderen Antrieb entfernbar und wieder in seine dargestellte Position zurückführbar. Die Ausbildung eines solchen Deckels und seines Antriebs ist den eingangs genannten US-Patentschriften zu entnehmen, so daß sich eine besondere Darstellung erübrigt. Eine Vorderwand und eine Rückwand fehlen bei dem Rahmen 14, so daß ein Vollbehälter 3 durch die Vorderfläche 52 in den Rahmen 14 überführt und ein Leerbehälter 22 durch die Rückfläche 53 aus ihm entfernt werden kann. Der Rahmen 14 ist durch Führungen 44 auf Schwenkarmen 45 geführt und von einem nicht dargestellten Antrieb in Richtung des Doppelpfeils 46 hin und her bewegbar. An dem Rahmen 14 befinden sich Klemmvorrichtungen 54 und 56, die im wesentlichen aus Pneumatikzylindern 57 bzw. 58, Kolbenstangen 59 bzw. 61 und Klemmplatten 62 bzw. 63 bestehen. Bei Betätigung der Pneumatikzylinder durch ein elektrisches Signal legen sich die Klemmplatten 62, 63 gegen einen Vollbehälter 3 in dem Rahmen 14, heben ihn um eine relativ kleine Strecke an (Pfeil 68), wobei er bis unter den Rahmendeckel 51 gelangt, und klemmen ihn dabei fest, so daß auch bei einer Verschwenkung des Rahmens 14 die Fixierung des Vollbehälters (und später des Leerbehälters) im Rahmen erhalten bleibt. Zum Freigeben eines Behälters wird der Druck von den Pneumatikzylindern 57 und 58 weggenommen, so daß die Klemmung aufgehoben wird und der Rahmen 14 wieder absinkt. Figur 2a zeigt den Behälter in geklemmtem, Figur 2b in freigegebenem Zustand. Es liegt im Rahmen der Erfindung, den Rahmen 14 zur Aufnahme von zwei oder mehr Behältern 3, 22 auszubilden.
Bei der Überführung eines Vollbehälters 3 in den Rahmen 14 wird der in diesem befindliche Leerbehälter 22 herausgeschoben und damit entfernt. Figur 11 zeigt einen halb eingeschobenen Vollbehälter 3 und einen entsprechend halb herausgeschobenen Leerbehälter 22. In Figur 1 sind die Behälterbewegungen abgeschlossen. Der Leerbehälter 22 ist auf eine Fläche 64 der Absenkvorrichtung 24 geschoben, die auf ein elektrisches Signal hin von einem Spindelantrieb 65, einem Zahnriemen oder dergleichen abgesenkt werden kann, bis der Leerbehälter 22 auf das Abförderband 26 übergeben ist, von dem er zu der Leerbehälterstation 28 abgefördert wird. Hub- und Absenkvorrichtungen für Leerbehälter sind in der Industrie für Behälterfüll- und Behälterentleerungsmaschinen vielfach bekannt und zum Beispiel in den US-Patentschriften 3 777 911, 3 655 080 und 3 527 369 beschrieben.After the description of the main components of the emptying device 1 will be discussed in detail below.
The feed belts 12 are guided over rollers 31, 32, 33 and 34, of which roller 34 via a toothed belt 36 of a controllable electric motor 37 and a Gear 38 is driven. The over rollers 39, 41, 42 and 43 guided Abförderbänder 26 are driven by the electric motor 37 and its transmission 38. At the feed station 17 is the frame 14, which, in particular Figure 2 shows, side walls 47, 48 and a lid 51 has. The lid 51 is removable from a particular drive and traceable back to its illustrated position. The formation of such a lid and its drive can be found in the aforementioned US patents, so that a special representation is unnecessary. A front wall and a rear wall are missing from the frame 14, so that a full container 3 can be transferred through the front surface 52 into the frame 14 and an empty container 22 can be removed from it by the rear surface 53. The frame 14 is guided by guides 44 on pivot arms 45 and movable by a drive, not shown, in the direction of the double arrow 46 back and forth. On the frame 14 are clamping devices 54 and 56, which consist essentially of pneumatic cylinders 57 and 58, piston rods 59 and 61 and clamping plates 62 and 63, respectively. Upon actuation of the pneumatic cylinder by an electrical signal put the clamping plates 62, 63 against a full container 3 in the frame 14, lift it by a relatively small distance (arrow 68), where it passes under the frame cover 51, and clamp him fixed, so that even with a pivoting of the frame 14, the fixation of the full container (and later of the empty container) is maintained in the frame. To release a container, the pressure from the pneumatic cylinders 57 and 58 is removed, so that the clamping is released and the frame 14 drops again. Figure 2a shows the container in clamped, Figure 2b in the released state. It is within the scope of the invention, the frame 14 for receiving two or more containers 3, 22 form.
When transferring a full container 3 into the frame 14, the empty container 22 located in it is pushed out and thus removed. Figure 11 shows a half inserted full container 3 and a corresponding half pushed out empty container 22. In Figure 1, the container movements are completed. The empty container 22 is pushed onto a surface 64 of the lowering device 24, which can be lowered in response to an electrical signal from a spindle drive 65, a toothed belt or the like, until the empty container 22 is transferred to the discharge conveyor 26, from which he to the empty container station 28th is carried away. Empty container lifting and lowering devices are widely known in the industry for container filling and container emptying machines and are described, for example, in US Pat. Nos. 3,777,911, 3,655,080 and 3,527,369.

Nach dem Überführen des Vollbehälters 3 in den Rahmen 14 an der Aufgabestation 17 wird der Rahmen auf ein Steuersignal hin von einem Motor 66 mit Getriebe 67 der Verschwenkeinrichtung 16 um eine Schwenkachse 69 verschwenkt, wobei der einen (oder mehrere) Vollbehälter 3 enthaltende Rahmen 14 einen Weg entsprechend Pfeil 18 ausführt und dabei zu der Entleerungsstation 19 bewegt wird. Schwenkeinrichtungen der verwendeten Art (manchmal auch Kippeinrichtungen genannt) sind vielfach bekannt, zum Beispiel durch den eingangs genannten Stand der Technik und durch zum Teil danach gebaute Entleerungsmaschinen (auch Magazinfüller genannt), so daß sie im einzelnen nicht mehr besonders beschrieben zu werden brauchen.
Ist der Rahmen 14 mit einem Vollbehälter 3 in der Entleerungsstation 19 angelangt, so wird er auf den oberen Rand 71 von zum Beispiel durch die US-Patentschrift 3 527 369 und die deutsche Patentschrift 19 39 395 sowie in der Zigarettenindustrie vielfach benutzte Entleerungsmaschinen bekannte auf- und abbewegbaren Wänden 72 gesetzt, die den oberen Abschluß des Behälters 21 bilden. Zwischen den Wänden 72, die in ihrer oberen Endposition dargestellt sind, und deren unteren Enden 73 an das feststehende obere Ende 74 des Magazin 21 anschließen, befinden sich Artikel, wie zum Beispiel Zigaretten, die bei der Bewegung des vorigen Vollbehälters 3 durch den Rahmen 14 in die Entleerungsstation 19 zugeführt worden sind.After transferring the full container 3 into the frame 14 at the feed station 17, the frame is pivoted to a control signal from a motor 66 with gear 67 of the pivoting device 16 about a pivot axis 69, wherein the one (or more) full container 3 containing frame 14 a Path according to arrow 18 executes and is thereby moved to the emptying station 19. Swivel devices of the type used (sometimes called tilting devices) are widely known, for example, by the above-mentioned prior art and partly built by emptying machines (also called magazine filler), so that they need not be described in detail in detail.
If the frame 14 has arrived at the emptying station 19 with a full container 3, it becomes known on the upper edge 71 of, for example, US Pat. No. 3,527,369 and German patent specification No. 19 39 395 and emptying machines frequently used in the cigarette industry. and movable walls 72 set, which form the upper end of the container 21. Between the walls 72, which are shown in their upper end position, and their lower ends 73 connect to the fixed upper end 74 of the magazine 21, there are articles, such as cigarettes, in the movement of the former full container 3 through the frame 14th have been supplied to the emptying station 19.

Die Oberfläche der Zigaretten sinkt wegen der Entnahme von Zigaretten zwecks Verpackung aus dem unteren Bereich des Magazins 21 ständig ab. Die Zufuhr eines neuen Vollbehälters 3 in seinem Rahmen 14 erfolgt aber schon, bevor die Oberfläche der Artikel zwischen den Wänden 72 deren untere Lage und damit den oberen Bereich 74 des Magazins 21 erreicht hat. Nachdem ein neuer Rahmen 14 mit darin befindlichem Vollbehälter 3 auf den oberen Rand 71 der in ihrer oberen Position befindlichen auf- und abbewegbaren Wände 72 aufgesetzt worden ist, wird ein ebenfalls nicht dargestellter an sich bekannter Antrieb aktiviert, der die Wände 72 nach unten entsprechend Pfeil 75 bewegt, wobei sie an den feststehenden Wänden des Magazins 21 vorbeigleiten. Hierzu kann zum Beispiel ein nicht dargestellter Pneumatikzylinder oder elektrischer Antrieb in an sich bekannter Weise den Rahmen 14 mit seinen Führungen 44 entlang der Schwenkarme 45 in Richtung des Pfeils 75 verschieben. Erreicht der obere Rand 71 der abgesenkten Wände 72 die Oberfläche der Artikel, so gibt ein mit dem oberen Rand der Wände 72 bewegter Sensor, zum Beispiel eine Lichtschranke 77 ein Signal ab, das den Senkantrieb der Wände 72 stoppt und den Deckel 51 des Rahmens 14 in bekannter Weise mittels eines nicht dargestellten Antriebs von dem Rahmen entfernt. Die Zigaretten können nun den Vollbehälter 3 nach unten verlassen, wobei die Fallhöhe infolge des Nachfahrens des Vollbehälters 3 in dem Rahmen 14 zu der Artikeloberfläche minimiert ist. Nach dem Entfernen des Deckels 51 bewegt der Antrieb der Wände 72 diese in bekannter Weise zusammen mit der Lichtschranke 77, dem auf dem oberen Rand 71 der Wände 72 sitzenden Rahmen 14 und dem Vollbehälter 3 entsprechend Pfeil 78 nach oben in die dargestellte obere Position der Wände 72. Der zugeführte Vollbehälter 3, der schon während der Hochbewegung der Wände 72 Artikel abgegeben hat, gibt diese entsprechend dem Abzug von Artikeln aus dem Magazin 21 fortlaufend weiter ab, bis die Lichtschranke 77 ein Ende der Artikelabgabe aus dem Vollbehälter, aus dem nunmehr ein Leerbehälter 22 geworden ist, feststellt. Die Lichtschranke 77 gibt nunmehr ein Steuersignal an den Schwenkantrieb 66, der den Rahmen 14 mit dem nunmehr leeren Behälter 22 in Richtung des Pfeils 23 zur Aufgabestation 17 zurückbewegt. Nach deren Erreichen wird die Klemmung des Leerbehälters 22 durch Desaktivieren der Klemmvorrichtungen 54, 56 gelöst, so daß der Leerbehälter 22 in seine Freigabelage entsprechend Pfeil 68 sinken kann. Danach wird ein neuer Vollbehälter 3 von den Förderbändern 12 zu der Aufgabestation 17 gefördert und in den Rahmen 14 überführt, wodurch der Leerbehälter 22 aus dem Rahmen 14 auf die Fläche 64, von der der vorige Leerbehälter zwischenzeitlich entfernt worden ist, geschoben wird. Damit ist ein Entleerungszyklus beendet.The surface of the cigarette drops because of the removal of cigarettes for packaging from the bottom of the magazine 21 for packaging. However, the supply of a new full container 3 in its frame 14 takes place before the surface of the article between the walls 72 has reached its lower position and thus the upper region 74 of the magazine 21. After a new frame 14 with therein full container 3 has been placed on the upper edge 71 of the located in its upper position up and down movable walls 72, a likewise not shown known drive is activated, the walls 72 down arrow 75, while they slide past the fixed walls of the magazine 21. For this purpose, for example, a not shown pneumatic cylinder or electric drive in a conventional manner, the frame 14 with its guides 44 along the pivot arms 45 in the direction of the arrow 75 move. When the upper edge 71 of the lowered walls 72 reaches the surface of the articles, a sensor moved with the upper edge of the walls 72, for example a light barrier 77, emits a signal which stops the lowering drive of the walls 72 and the cover 51 of the frame 14 removed in a known manner by means of a drive, not shown, from the frame. The cigarettes can now leave the full container 3 down, wherein the drop height is minimized as a result of the Nachfahr the full container 3 in the frame 14 to the article surface. After removal of the lid 51, the drive of the walls 72 move them in a known manner together with the light barrier 77, the frame 14 seated on the upper edge 71 of the walls 72 and the full container 3 as indicated by arrow 78 upwardly in the illustrated upper position of the walls 72. The supplied full container 3, which has already delivered 72 items during the upward movement of the walls, this continues according to the deduction of articles from the magazine 21 continues from until the photocell 77 an end of the article delivery from the full container, from the now Empty container 22 has been detected. The light barrier 77 is now a control signal to the rotary actuator 66, the moved back the frame 14 with the now empty container 22 in the direction of arrow 23 to the loading station 17. After reaching the clamping of the empty container 22 is released by deactivating the clamping devices 54, 56, so that the empty container 22 can sink into its release position according to arrow 68. Thereafter, a new full container 3 is conveyed by the conveyor belts 12 to the feed station 17 and transferred into the frame 14, whereby the empty container 22 from the frame 14 on the surface 64 from which the previous empty container has been temporarily removed, is pushed. This completes a draining cycle.

Der Unterschied der Variante der Erfindung gemäß den Figuren 13 bis 16 im Vergleich mit der Ausführungsform gemäß den Figuren 1 bis 12 besteht im wesentlichen darin, daß zur Überführung der Vollbehälter 3 in den Rahmen 14 der Schwenkeinrichtung 16 nicht die Zuförderbänder 12 verwendet werden, sondern ein besonderer Antrieb, der die Vollbehälter in der Endphase der Zuförderung erheblich schneller transportieren und in den Rahmen 14 überführen kann. Hierdurch wird die Leistungsfähigkeit der Entleerungsvorrichtung erheblich gesteigert. Die Schwenkeinrichtung 16, das Magazin mit den bewegbaren Wänden, die Absenkvorrichtung mit der Absenkfläche 64 und den Abförderbändern sind ausgebildet wie bei Figuren 1 bis 12 und brauchen daher nicht mehr dargestellt und beschrieben werden.The difference of the variant of the invention according to Figures 13 to 16 in comparison with the embodiment according to Figures 1 to 12 is essentially that for the transfer of the full container 3 in the frame 14 of the pivoting device 16, not the feed belts 12 are used, but a special drive that can transport the full container in the final phase of the feed much faster and can transfer into the frame 14. As a result, the performance of the emptying device is significantly increased. The pivoting device 16, the magazine with the movable walls, the lowering device with the lowering surface 64 and the Abförderbändern are formed as in figures 1 to 12 and therefore need not be shown and described.

In Figur 13 ist die Schwenkeinrichtung 16 dargestellt, die den Rahmen 14 mit einem Vollbehälter 3 in die Entleerungsposition 19 geschwenkt hat. Im Bereich der Zuförderbänder 12 und der Vollschragenstation 11 befindet sich eine Aufnahme 81 für einen Vollbehälter 3, die an einem Antrieb, vorzugsweise einem Linearantrieb 82 zum Beispiel in Form eines sogenannten kolbenstangenlosen Pneumatikzylinders 83 befestigt ist. Derartige Zylinder haben außer dem innen angeordneten Kolben auch eine innen befindliche Kolbenstange, mit der die Aufnahme 81 entweder durch einen abgedichteten Schlitz oder berührungslos (z.B. magnetisch) verbunden ist, und entsprechend Pfeil 84 in Richtung auf die Aufgabestation 17, entsprechend Pfeil 86 in entgegengesetzter Richtung bewegbar ist. An der der Behälterstation 11 zugewandten Seite des Linearantriebes 82, der auch als Zahnstangen- oder Zahnriemenantrieb ausgebildet sein kann, befindet sich ein Hubelement 87 in Form eines Hubzylinders 88, dessen Kolbenstange 89 den Linearantrieb 82 einseitig anheben, d. h. um eine Drehachse 91 verschwenken kann. Hierdurch wird, wie Figur 14 zeigt, die Aufnahme 81 mit dem Vollbehälter 3 ebenfalls angehoben, wodurch beide Elemente leicht kippen (in Figur 14 nach rechts), so daß die Zigaretten 2 sich mit ihren Filterenden 2a an der Rückwand 7 ihres Behälters abstützen können und die Gefahr des Herausfallens der Zigaretten 2 aus dem Behälter auch bei großen Linearbeschleunigungen oder Verzögerungen verringert wird. Figur 13 zeigt die Aufnahme 81 und den direkt darüber befindlichen Vollbehälter 3 in der Stellung, in der die Förderbänder 12 den Vollbehälter 3 an die Aufnahme 81 abgegeben haben; Figur 14 zeigt die Aufnahme 81 und den Vollbehälter 3 in gekippter Lage kurz vor Erreichen der Aufgabestation 17, in der sich der Rahmen 14 mit einem Leerbehälter 22 befindet.In Figure 13, the pivoting device 16 is shown, which has pivoted the frame 14 with a full container 3 in the emptying position 19. In the area of the feed belts 12 and the full rack station 11 is a receptacle 81 for a full container 3, which is attached to a drive, preferably a linear drive 82, for example in the form of a so-called rodless pneumatic cylinder 83. Such cylinders have in addition to the piston inside also an internal piston rod, with which the receptacle 81 is connected either by a sealed slot or non-contact (eg magnetic), and according to arrow 84 in the direction of the feed station 17, corresponding arrow 86 in the opposite direction is movable. At the container station 11 side facing the linear drive 82, which may also be designed as a rack or belt drive, there is a lifting element 87 in the form of a lifting cylinder 88, the piston rod 89, the linear drive 82 unilaterally lift, d. H. can pivot about a rotation axis 91. As a result, as shown in Figure 14, the receptacle 81 is also raised with the full container 3, whereby both elements tilt slightly (in Figure 14 to the right), so that the cigarettes 2 can be supported with their filter ends 2a on the rear wall 7 of their container and the risk of the cigarettes 2 falling out of the container is reduced even in the case of large linear accelerations or delays. FIG. 13 shows the receptacle 81 and the full container 3 located directly above it in the position in which the conveyor belts 12 have delivered the full container 3 to the receptacle 81; Figure 14 shows the receptacle 81 and the full container 3 in a tilted position shortly before reaching the feed station 17, in which the frame 14 is located with an empty container 22.

Figur 15 zeigt, wie der im Vergleich zu den Förderbändern 12 sehr schnelle Linearantrieb 82 die Aufnahme 81 mit dem Vollbehälter 3 schon teilweise in den Rahmen 14 geschoben hat, wobei eine Nase 92 den Leerbehälter 22 teilweise aus dem Rahmen 14 auf die Absenkfläche 64 entfernt hat.Figure 15 shows how the compared to the conveyor belts 12 very fast Linear drive 82 has the receptacle 81 with the full container 3 already partially pushed into the frame 14, wherein a nose 92 has the empty container 22 partially removed from the frame 14 on the lowering surface 64.

Figur 16 zeigt den beendeten Überführungsvorgang, d. h. ein Vollbehälter 3 ist in den Rahmen 14 überführt und ein Leerbehälter 22 aus dem Rahmen entfernt und auf die Absenkfläche 64 geschoben worden, die ihn danach nach unten absenkt, von wo aus er abgefördert wird. Nach dem Überführungsvorgang und dem Beginn der Schwenkbewegung wird die leere Aufnahme 81 entsprechend Pfeil 86 von dem Linearantrieb 82 zurückgefördert, wobei das Hubelement 87 den Linearantrieb 82 und die daran befestigte Aufnahme 81 wieder in die aus Figur 13 hervorgehende Position absenkt. Im übrigen arbeitet die Vorrichtung, wie anhand der Figuren 1 bis 12 beschrieben, insbesondere was die Schwenkbewegung, die Höhenbewegungen der Magazinwände, die Abförderbewegung der Leerbehälter und die Klemmung eines Behälters in dem Rahmen anbelangt.Figure 16 shows the completed transfer operation, d. H. a full container 3 has been transferred to the frame 14 and an empty container 22 has been removed from the frame and pushed onto the lowering surface 64, which then lowers it down from where it is carried away. After the transfer process and the beginning of the pivoting movement, the empty receptacle 81 is fed back according to arrow 86 from the linear drive 82, wherein the lifting element 87, the linear actuator 82 and the attached receptacle 81 drops back into the position resulting from Figure 13 position. Moreover, the device operates, as described with reference to Figures 1 to 12, in particular as regards the pivoting movement, the height movements of the magazine walls, the Abförderbewegung the empty containers and the clamping of a container in the frame.
