Description

Die Erfindung betrifft eine Vorrichtung zum Abpacken von Beuteln mit einem Siegelrand an wenigstens zwei gegenüberliegenden Seiten mittels einer Fördereinrichtung in einen nachgeordneten Verpackungsbehälter.The invention relates to a device for packaging bags with a sealing edge on at least two opposite sides by means of a conveyor into a downstream packaging container.

Beutel mit umlaufendem Siegelrand werden beispielsweise eingesetzt von Verpackung von pulverförmigem Gut wie zum Beispiel Kaffeepulver oder Suppenpulver. Diese Beutel müssen vom Hersteller zur Lieferung an die Abnehmer in bestimmter Stückzahl in Kartons abgepackt werden. Hierzu werden diese auf eine Fördereinrichtung gegeben, die die Beutel nacheinander in einem Verpackungsbehälter ablegt.Pouches with a circumferential sealing edge are used, for example, for packaging powdery goods such as coffee powder or soup powder. These bags have to be packed in boxes by the manufacturer for delivery to the customers. For this purpose, they are placed on a conveyor device, which places the bags one after the other in a packaging container.

Infolge der bauchigen Querschnittsform derartiger Beutel kommt es hierbei immer wieder zu Verdrehungen der Beutel um ihre Vertikalachse auf der Fördereinrichtung, so daß eine einwandfreie Ablage im Verpackungsbehälter nicht immer gewährleistet ist und die Abpackleistung der vorbekannten Vorrichtungen sehr begrenzt ist.As a result of the bulbous cross-sectional shape of such bags, the bags repeatedly twist about their vertical axis on the conveying device, so that perfect storage in the packaging container is not always guaranteed and the packaging performance of the previously known devices is very limited.

Bei den bekannten Vorrichtungen zum Abpacken von Beuteln sind darüberhinaus noch Zwischenstationen erforderlich, um diese konstruktiven Nachteile zu berücksichtigen:In the known devices for packaging bags, intermediate stations are also required in order to take these design disadvantages into account:

Die Beutel werden dabei einem Egalisator zugeführt, durch den der Packungsinhalt gleichmäßig in dem verfügbaren Beutelvolumen verteilt werden soll, so daß die Beutel in ihrer Gesamtfläche eine möglichst gleichmäßige Dicke aufweisen, um eine Stapelung einer größeren Anzahl von Beuteln überhaupt erst zu ermöglichen.The bags are fed to a leveling device through which the contents of the pack are to be distributed evenly in the available bag volume, so that the total area of the bags is as uniform as possible in order to enable a large number of bags to be stacked in the first place.

Die derart vorbehandelten Beutel werden dann zunächst in einer weiteren Zwischenstation in einem kassettenartigen Behälter in der vorbestimmten Menge gestapelt und dann gemeinsam in den nachgeordneten Verpackungsbehälter eingeschoben.The bags pretreated in this way are then first stacked in a further intermediate station in a cassette-like container in the predetermined amount and then pushed together into the downstream packaging container.

Trotz dieser aufwendigen Maßnahmen bleibt die Abpackleistung einer solchen z.B. aus der GB-A 2 017 035 vorbekannten Vorrichtung auf etwa 200 Beutel/Minute begrenzt.Despite these complex measures, the packaging performance of such a from GB-A 2 017 035 previously known device limited to about 200 bags / minute.

Aufgabe der Erfindung ist es daher, eine derartige Vorrichtung so weiterzubilden, daß die Abpackleistung, also die Zahl der pro Zeiteinheit in den Verpackungsbehälter förderbaren Beutel wesentlich gesteigert wird.It is therefore an object of the invention to develop such a device in such a way that the packaging performance, that is to say the number of bags which can be conveyed into the packaging container per unit of time, is substantially increased.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.

Durch die beidseitige Erfassung der Beutel an ihren gegenüberliegenden Siegelrändern sind Drehungen der Beutel um ihre Vertikalachse praktisch ausgeschlossen und die Beutel können in dichtem Abstand mit hoher Fördergeschwindigkeit in den nachgeschalteten Verpackungsbehälter abgelegt werden.Due to the double-sided detection of the bags at their opposite sealing edges, rotation of the bags around their vertical axis is practically impossible and the bags can be placed in close proximity at a high conveying speed in the downstream packaging container.

Insbesondere kann dabei auf weitere Zwischenstationen, wie Egalisatoren oder Zwischenkassetten verzichtet werden.In particular, further intermediate stations, such as levelers or intermediate cassettes, can be dispensed with.

Durch die erfindungsgemäßen Maßnahmen ist daher eine Steigerung der Abpackleistung um das 10- bis 100fache möglich, beispielsweise sind bei einer Beutellänge von 65 mm Abpackleistungen von 7000 Stück pro Minute, bei einer Beutellänge von 150 mm von 4000 Stück pro Minute erreichbar.The measures according to the invention therefore make it possible to increase the packaging performance by 10 to 100 times, for example with a bag length of 65 mm, packaging performance of 7000 pieces per minute, and with a bag length of 150 mm, 4000 pieces per minute.

Weitere Ausbildungen der Erfindung sind aus den Unteransprüchen entnehmbar.Further embodiments of the invention can be found in the subclaims.

Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung wird anhand von Zeichnungen näher erläutert, es zeigen:

  • Figur 1: Einen Vertikalquerschnitt in der Transportrichtung durch die erfindungsgemäße Vorrichtung,
  • Figur 2: eine Aufsicht auf die Vorrichtung gemäß Figur 1,
  • Figur 3: einen Vertikalschnitt in der Ebene 111-111 der Figur 1.
An embodiment of the device according to the invention is explained in more detail with reference to drawings, in which:
  • FIG. 1: a vertical cross section in the transport direction through the device according to the invention,
  • FIG. 2: a top view of the device according to FIG. 1,
  • Figure 3: a vertical section in the plane 111-111 of Figure 1.

Die erfindungsgemäße Vorrichtung beinhaltet eine Fördereinrichtung 10 und einen nachgeschalteten Verpackungsbehälter 30, in den die Beutel 20 nacheinander eingeführt werden, so daß sie dort aufeinander gestapelt werden.The device according to the invention includes a conveyor 10 and a downstream packaging container 30, into which the bags 20 are inserted one after the other so that they are stacked on top of one another there.

Die Fördereinrichtung 10 besteht aus einem rechten Förderbandpaar 11A,11B (Figur 3) und einem linken Förderbandpaar 12A,12B, deren Abstand x einstellbar ist, wie dies durch die gestrichelte Darstellung eines Förderbandpaares in den Figuren 2 und 3 angedeutet ist. Die Förderbänder laufen über Rollen, die an vier horizontal und parallel zueinander gelagerten Achsen angebracht sind, wobei die Achsen in entsprechenden Lagerböckchen gehalten sind und zumindest eine Achse von einem Motor 13 angetrieben ist, beispielsweise einem GleichstromMotor mit Getriebeaufsatz, um eine variable Transportgeschwindigkeit der Förderbandpaare zu ermöglichen.The conveyor device 10 consists of a right conveyor belt pair 11A, 11B (FIG. 3) and a left conveyor belt pair 12A, 12B, the distance x of which is adjustable, as indicated by the broken line of a conveyor belt pair in FIGS. 2 and 3. The conveyor belts run over rollers which are attached to four horizontally and parallel axes, the axes being held in corresponding bearing blocks and at least one axis being driven by a motor 13, for example a DC motor with a gear attachment, in order to achieve a variable transport speed of the conveyor belt pairs enable.

Der horizontale Abstand x der Förderbandpaare ist nun so auf die zu fördernden Beutel 20 abgestimmt, daß die Förderbänder die beiden gegenüberliegenden Siegelränder 20A,20B der Beutel kraftschlüssig zwischen sich einschließen, wobei ein ausreichender Kraftschluß durch eine entsprechende Regulierung des Vertikalabstandes z der übereinander liegenden Förderbänder erreichbar ist.The horizontal distance x of the conveyor belt pairs is now matched to the bags 20 to be conveyed in such a way that the conveyor belts enclose the two opposite sealing edges 20A, 20B of the bags in a force-fitting manner between them, an adequate frictional connection being achievable by corresponding regulation of the vertical distance z of the conveyor belts lying one above the other is.

Dadurch ist gewährleistet, daß bei ordnungsgemäßer Einführung der Beutel 20 in die Fördereinrichtung 10 diese auch ohne Verdrehungen um ihre Vertikalachse am Ausgabeende der Fördereinrichtung ausgeworfen werden.This ensures that when the bags 20 are properly introduced into the conveyor 10, they are ejected at the output end of the conveyor even without twisting about their vertical axis.

Unmittelbar an der Ausgabeseite der Fördereinrichtung 10 befindet sich der Verpackungsbehälter 30, dessen Eingabeöffnung 31 sich im oberen Randbereich einer Vorderseite befindet, wobei die höhenmäßige Anordnung des Verpackungsbehälters 30 so ist, daß die Beutel 20 mit hoher Geschwindigkeit in die Eingabeöffnung 31 geschossen werden, an der Rückwand 33 des Verpackungsbehälters 30 abprallen und dann nach unten fallen und sich dort stapeln.Immediately on the delivery side of the conveyor 10 is the packaging container 30, the input opening 31 of which is located in the upper edge region of a front side, the height arrangement of the packaging container 30 being such that the bags 20 are shot into the input opening 31 at high speed, at which Bounce off rear wall 33 of packaging container 30 and then drop down and stack there.

Der Abstand y der Eingabeöffnung 31 von der Abgabeseite der Fördereinrichtung 10 kann dabei durch entsprechende Verschiebung des Verpackungsbehälters gegenüber dem Rahmen der Fördereinrichtung 10 an die Abmessungen der Beutel 20 und die Fördergeschwindigkeit der Fördereinrichtung 10 angepaßt werden.The distance y of the input opening 31 from the delivery side of the conveyor 10 can be adjusted to the dimensions of the Beu by appropriate displacement of the packaging container relative to the frame of the conveyor tel 20 and the conveyor speed of the conveyor 10 can be adjusted.
