Description

Stand der TechnikState of the art

Die Neuerung geht aus von einer Verpackungsvorrichtung nach der Gattung des Hauptanspruchs. Bei einer durch die US-PS 32 69 091 bekannt gewordenen Vorrichtung dieser Art hat die das zu verpackende Gut zuführende Fördereinrichtung U-förmige Becher mit festen Seitenwänden. Von oben teilweise in die Becher abgesenkte Preßplatten drücken das Gut so zusammen, daß sein Querschnitt dem der aufnehmenden Faltschachtel entspricht. Schwierigkeiten bereitet das Einsetzen von Beutelpackungen in die Becher, da Luft enthaltende, kissenförmige Schlauchbeutelpackungen nicht formstabil sind und ihre Breite größer ist als die der Faltschachteln. Es ist daher eine Verpackungsvorrichtung anzustreben, die die Beutelpackungen sicher übernimmt, in eine der Faltschachteln entsprechende Form bringt und in diese einführt.The innovation is based on a packaging device according to the type of the main claim. In a device of this type which has become known from US Pat. No. 3,269,091, the conveying device which is to be packaged has U-shaped cups with fixed side walls. Press plates partially lowered into the cups from above compress the goods so that their cross-section corresponds to that of the receiving folding box. It is difficult to insert pouch packs into the cups, since air-containing pillow-shaped tubular pouch packs are not dimensionally stable and their width is larger than that of the folding boxes. It is therefore desirable to have a packaging device which reliably takes over the bag packs, brings them into a shape corresponding to the folding boxes and introduces them into them.

Vorteile der ErfindungAdvantages of the invention

Die neuerungsgemäße Verpackungsvorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat den Vorteil, daß die Becher der Gutfördereinrichtung zur Aufnahme von Beutelpackungen zu einem trichterförmigen Querschnitt geweitet werden können, so daß die von einer Herstellmaschine kommenden Beutelpackungen ohne besondere auf die Beutelform wirkende Einrichtungen in die Becher abgeworfen werden können. Ferner kann die schwenkbare Wand der Becher die eingelegten Beutelpackungen überpressen, d.h.; enger zusammenpressen als die Weite der aufnehmenden Faltschachteln.The new packaging device with the characterizing features of the main claim has the advantage that the cups of the material conveying device for receiving bag packs can be expanded to a funnel-shaped cross-section, so that the bag packs coming from a manufacturing machine are thrown into the cups without special devices acting on the bag shape can. Furthermore, the pivotable wall of the cups can press over the inserted bag packs, i.e.; Press closer together than the width of the receiving folding boxes.

Es zeigen Figur 1 einen Teil einer Verpackungsvorrichtung für Beutelpackungen in Vorderansicht und Figur 2 die Verpackungsvorrichtung nach Figur 1 im Querschnitt in der Ebene 11-11 der Figur 1.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a part of a packaging device for bag packs in a front view and FIG. 2 shows the packaging device according to FIG. 1 in cross section in the plane 11-11 of FIG. 1.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Eine Vorrichtung zum Verpacken von Beutelpackungen 3 in Faltschachteln 4 hat eine erste umlaufende, endlose Fördereinrichtung 10 mit Mitnehmern 11 für die Faltschachteln 4. Diese Fördereinrichtung 10 führt geöffnete Faltschachteln 4 in einer horizontalen Strecke zunächst einer Fülleinrichtung und danach nicht dargestellten Schließeinrichtungen zu. Die Fülleinrichtung besteht aus einer zweiten umlaufenden, endlosen Fördereinrichtung 12, welche die erste Fördereinrichtung 10 auf einer bestimmten horizontalen Wegstrecke in gleicher Höhe begleitet. Die zweite Fördereinrichtung 12 hat zur Aufnahme und zum Zuführen der zu verpackenden Beutelpackungen 3 U-förmige Becher 13.A device for packaging bag packs 3 in folding boxes 4 has a first circulating, endless conveying device 10 with drivers 11 for the folding boxes 4. This conveying device 10 leads opened folding boxes 4 in a horizontal path initially to a filling device and then not shown closing devices. The filling device consists of a second circulating, endless conveyor device 12 which accompanies the first conveyor device 10 over a certain horizontal distance at the same height. The second conveyor 12 has 3 U-shaped cups 13 for receiving and feeding the bag packs to be packaged.

Die Becher 13 bestehen aus einem L-förmigen Teil mit einem Boden 14 und einer mit diesem starr verbundenen, in Förderrichtung hinteren senkrechten Wand 15, deren oberer Teil nach hinten abgewinkelt ist. Die in Förderrichtung vordere Wand 16 ist in einem bestimmten Winkelbereich schwenkbar. Sie wird von zwei Hebeln 17 getragen, welche auf einer in Lagerböcken 18 unterhalb des Bodens 14 drehbar gelagerten Achse 19 sitzen. Die Hebel 17 greifen durch Aussparungen 20 im vorderen Randbereich des Bodens 14 der Becher 13. Eine an einem der Hebel 17 und am Boden 14 eingehängte Zugfeder 21 verschwenkt die vordere Wand 16 in eine Schräglage, so daß sich die Becher 13 nach oben trichterförmig weiten. Einer der Hebel 17 hat einen rechtwinklig abstehenden Arm 22 mit einer Rolle 23, die in einem Teilbereich der oben erwähnten gemeinsamen Wegstrecke auf einer ortsfesten Steuerschiene 24 mit einem ansteigenden Teil 25, einem waagerechten Teil 26 und einem abfallenden "Teil 27 läuft. Die Becher 13 sind mittels vom Boden 14 nach unten abstehender Laschen 28 an der zweiten Fördereinrichtung 12 befestigt, die wie die erste Fördereinrichtung 10 aus einem endlosen, um Umlenkräder geführten Kettenpaar besteht.The cups 13 consist of an L-shaped part with a bottom 14 and a rigidly connected to this, in the conveying direction rear vertical wall 15, the upper part is angled backwards. The front wall 16 in the conveying direction can be pivoted in a certain angular range. It is carried by two levers 17 which are seated on an axle 19 which is rotatably mounted in bearing blocks 18 below the base 14. The levers 17 engage through cutouts 20 in the front edge region of the base 14 of the cups 13. A tension spring 21 suspended on one of the levers 17 and on the base 14 pivots the front wall 16 into an inclined position, so that the cups 13 widen upwards in a funnel shape. One of the levers 17 has a right-angled arm 22 with a roller 23 which runs in a partial region of the above-mentioned common path on a stationary control rail 24 with a rising part 25, a horizontal part 26 and a falling part 27. The cup 13 are fastened to the second conveyor 12 by means of tabs 28 projecting downward from the bottom 14, which like the first conveyor 10 consists of an endless pair of chains guided around deflection wheels.

Oberhalb der zweiten Fördereinrichtung 12 ist eine dritte endlose Fördereinrichtung 30 angeordnet, die sich ebenfalls in einem Teilbereich der oben angeführten, gemeinsamen Wegstrecke erstreckt. Diese Fördereinrichtung 30, die ebenfalls aus einem Kettenpaar besteht, trägt an Laschen 31 Platten 32, welche in Deckung mit den Bechern 13 führbar sind, so daß sie die Becher 13 nach oben abschließen.A third endless conveyor device 30 is arranged above the second conveyor device 12 and also extends in a partial area of the above-mentioned common path. This conveyor 30, which also consists of a pair of chains, carries on plates 31 plates 32, which can be guided in congruence with the cups 13, so that they close the cups 13 at the top.

Die beschriebene Verpackungsvorrichtung. arbeitet wie folgt:

  • Die drei Fördereinrichtungen 10, 12 und 30 laufen mit gleicher Geschwindigkeit um und sind so synchronisiert, daß auf der gemeinsamen Wegstrecke die Becher 13 mit den geförderten Faltschachteln 4 fluchten und die Platten 32 eine obere Begrenzung der Becher 13 bilden. An einer Stelle vor Eintauchen der Platten 32 in die Becher 13 werden in diese je eine Beutelpackung 3 eingelegt, wobei die vordere Wand 16 der Becher 13 nach vorne abgeschwenkt ist, so daß sich der Becher 13 trichterförmig nach oben weitet. Wenn im weiteren Verlauf eine Platte 32 den Becher 13 in paralleler Lage zum Boden 14 nach oben abschließt, läuft die Rolle 23 auf den ansteigenden Teil 25 der Steuerschiene 24 auf, wobei die vordere Wand 16 nach hinten verschwenkt wird. Dabei nimmt sie schließlich eine Lage ein, in der sie von der Senkrechten um einen kleinen Winkel nach hinten zur festen Wand 15 hin geneigt ist. Bei dieser Schwenkbewegung wird der im Becher 13 liegenden Beutelpackung 3, die ursprünglich die Form eines Kissens hat, in die von den Wänden 14, 15, 16 des Bechers 13 und der Platte 32 vorgegebene Form eines Quaders umgeformt, wobei insbesondere die Breite der Beutelpackung 3 verringert wird. Die große Verringerung der Weite eines Bechers 13 wird insbesondere dadurch erzielt, daß die Schwenkachse 19 der schwenkbaren Wand 16 unterhalb der Ebene des Bodens 14 der Becher 13 angeordnet ist. Sobald eine Beutelpackung 3 die Umformung zum Quader erfahren hat, dringt ein mitlaufender Schieber 33 in Längsrichtung des Bechers 13 in diesen ein und durchquert diesen, wobei die Beutelpackung 3 in die fluchtend geförderte Faltschachtel 4 eingeschoben wird. Danach hebt die Platte 32 ab, die vordere Wand 16 schwenkt im Bereich des abfallenden Teils 27 der Sheuerschiene 24 wieder nach vorne und der Schieber 33 kehrt in seine Ausgangslage zurück.
The packaging device described. works as follows:
  • The three conveyors 10, 12 and 30 run at the same speed and are synchronized so that the cups 13 are aligned with the conveyed folding boxes 4 on the common path and the plates 32 form an upper limit of the cups 13. At a point before the plates 32 are immersed in the cups 13, a bag pack 3 is inserted into each of them, the front wall 16 of the cups 13 being pivoted forward so that the cups 13 widen upwards in a funnel shape. If, in the further course, a plate 32 closes off the cup 13 in a position parallel to the bottom 14, the roller 23 runs onto the rising part 25 of the control rail 24, the front wall 16 being pivoted backwards. In doing so, it finally assumes a position in which it is inclined from the vertical by a small angle backwards to the fixed wall 15. During this pivoting movement of the bag pack 3 lying in the cup 13, which originally has the shape of a pillow, into which the The walls 14, 15, 16 of the cup 13 and the plate 32 are shaped into a predetermined shape of a cuboid, in particular the width of the bag pack 3 being reduced. The large reduction in the width of a cup 13 is achieved in particular in that the pivot axis 19 of the pivotable wall 16 is arranged below the plane of the bottom 14 of the cup 13. As soon as a bag pack 3 has undergone the forming of a cuboid, a moving slide 33 penetrates and traverses the cup 13 in the longitudinal direction thereof, the bag pack 3 being pushed into the folding box 4, which is conveyed in alignment. Then the plate 32 lifts off, the front wall 16 pivots again in the region of the falling part 27 of the slide rail 24 and the slide 33 returns to its initial position.

Ergänzend wird bemerkt, daß zum Umformen von kissenförmigen Beutelpackungen in eine Form, deren Querschnitt dem der aufnehmenden Faltschachteln entspricht, nicht nur die in Förderrichtung vordere Wand der Becher schwenkbar angeordnet sein kann, sondern auch die hintere Wand oder, je nach Geometrie der Beutelpackung, auch beide vom Boden abstehende Wände eines Bechers. Ferner kann die die Wand 16 verschwenkende Steuerschiene 24 so gestaltet sein, daß die Wand 16 bereits gegen die hintere Wand 15 der Becher 13 verschwenkt wird, bevor die Platten 32 gegen die Becher 13 abgesenkt werden und diese nach oben abschließen.In addition, it is noted that for forming pillow-shaped bag packs into a shape whose cross-section corresponds to that of the receiving folding boxes, not only the front wall of the cups can be pivoted in the conveying direction, but also the rear wall or, depending on the geometry of the bag pack, also both walls of a cup protruding from the floor. Furthermore, the control rail 24 pivoting the wall 16 can be designed such that the wall 16 is already pivoted against the rear wall 15 of the cups 13 before the plates 32 are lowered against the cups 13 and close them off at the top.
