Description

Verpressvorrichtung für mit geklebten Böden versehene Säcke Pressing device for bags provided with glued bottoms

Die Erfindung betrifft eine Verpressvorrichtung für mit geklebten Böden versehene Säcke gemäß des Anspruchs 1.The invention relates to a pressing device for bags provided with glued bottoms according to claim 1.

Die geklebten Böden von Säcken, insbesondere von Papiersäcken, müssen unmittelbar nach der Verklebung zusammengedrückt werden, um zu verhindern, dass sich die Bodenfaltungen unter Lösung der Verklebung aufrichten. Außerdem wird durch die Verpressung der Bodenbereiche eine haltbare Verklebung erzielt.The glued bottoms of sacks, especially paper sacks, must be pressed together immediately after gluing in order to prevent the bottom folds from erecting while loosening the glue. In addition, a durable bond is achieved by pressing the floor areas.

Zu diesem Zweck werden die Säcke zunächst in einer Schuppenbildungsstation schuppenartig übereinander gelegt. Anschließend werden die Böden der Säcke in der Verpressvorrichtung verpresst. Nach dem Verpressvorgang werden die Säcke in einer Sackstapelstation gestapelt und abtransportiert.For this purpose, the sacks are first placed on top of one another in a scale-forming station. The bottoms of the sacks are then pressed in the pressing device. After the pressing process, the bags are stacked in a bag stacking station and transported away.

Bei der aus der DE 40 02 156 A1 bekannten Verpressvorrichtung werden die Sackböden in Pressbänder umfassende Förderstrecken gefördert, wobei die Pressbänder die Böden der Säcke zusammendrücken. Um eine lange Verweildauer der einzelnen Säcke in der Verpressstation zu erreichen, weist diese mindestens zwei Presszylinder auf, die von den Pressbändern umschlungen werden, so dass die Pressbänder einen S-förmigen oder einen mehrfach S-förmigen Weg zurücklegen.In the pressing device known from DE 40 02 156 A1, the bag bottoms are conveyed in conveyor belts comprising press belts, the press belts compressing the bottoms of the bags. In order to achieve a long residence time of the individual bags in the pressing station, the latter has at least two press cylinders which are wrapped around by the press belts, so that the press belts cover an S-shaped or a multiple S-shaped path.

Bekannte Verpressvorrichtungen sind für die Bedienung auf einer Längsseite des Maschinengestells ausgelegt. Oft sind diese Verpressvorrichtungen Teil eines größeren Systems wie eines Bodenlegers. Im alltäglichen Betrieb einer derartigen Ver- pressvorrichtung muss das Bedienpersonal zum Teil jedoch auch Arbeiten auf der anderen Längsseite der Verpressvorrichtung beziehungsweise des Systems ausführen. Die beidseitige Bedienung der Verpressvorrichtung ist jedoch nicht möglich, da das Bedienpersonal nicht auf die andere Längsseite der Verpressvorrichtung gelangen kann, ohne den Bedienbereich der Verpressvorrichtung für eine gewisse Zeit zu verlassen.Known pressing devices are designed for operation on one long side of the machine frame. Often these crimping devices are part of a larger system like a floor layer. In the daily operation of such a However, the operator must also partially carry out work on the other long side of the pressing device or the system. However, operating the pressing device on both sides is not possible since the operating personnel cannot get to the other long side of the pressing device without leaving the operating area of the pressing device for a certain time.

Aufgabe der vorliegenden Erfindung ist es daher, eine Verpressvorrichtung vorzuschlagen, welche eine beidseitige Bedienung der Verpressvorrichtung oder des die Verpressvorrichtung umfassenden Systems ermöglicht.The object of the present invention is therefore to propose a pressing device which enables the pressing device or the system comprising the pressing device to be operated on both sides.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Demnach sind die die Pressbänder führenden und/oder antreibenden Antriebsmittel, Führungsmittel und/oder Presszylinderpaare derart im Maschinengestell angeordnet, dass die Pressbänder über zumindest eine brückenartig ausgebildete Stelle des Maschinengestells geführt werden. Das Maschinengestell weist in dem unter der brückenartig ausgebildeten Stelle befindlichen Bereich einen begehbaren Freiraum auf. Dieser Freiraum kann vom Bedienpersonal dazu genutzt werden, um von einer Längsseite des Maschinengestells auf die andere Längsseite zu gelangen. Das Maschinengestell kann an dieser Stelle einen oder mehrere Träger aufweisen, in welchem oder in welchen die die Pressbänder führenden Führungsmittel gelagert sind. Führungsmittel können dabei Rollen oder Walzen sein, auf denen die Pressbänder geführt werden. Die Rollen oder Walzen können auch angetrieben sein, so dass sie Antriebsmittel für die Pressbänder darstellen. Jedoch können die Pressbänder in dem Bereich der brückenartig ausgebildeten Stelle auch ohne jegliche Unterstützung durch Antriebs- oder Führungsmittel geführt werden. Das Maschinengestell kann an dieser Stelle unterbrochen sein.According to the invention, this object is achieved by the features of the characterizing part of claim 1. Accordingly, the drive means, guide means and / or press cylinder pairs guiding and / or driving the press belts are arranged in the machine frame in such a way that the press belts are guided over at least one bridge-like location on the machine frame. The machine frame has an accessible space in the area under the bridge-like area. This free space can be used by the operating personnel to get from one long side of the machine frame to the other long side. At this point, the machine frame can have one or more supports in which or in which the guide means guiding the press belts are mounted. Guide means can be rollers or rollers on which the press belts are guided. The rollers or rollers can also be driven so that they represent drive means for the press belts. However, the press belts can also be guided in the region of the bridge-like location without any support from drive or guide means. The machine frame can be interrupted at this point.

In einer vorteilhaften Weiterbildung befindet sich die brückenartig ausgebildete Stelle des Maschinengestells unmittelbar hinter der Schuppenbildungsstation. Bei einer solchen Anordnung verlaufen die der Schuppenbildungsstation folgenden Pressbänder vorteilhafterweise zunächst ansteigend, um dann eine Höhe zu erreichen, die einen ausreichenden Freiraum im anschließenden Bereich zulässt. Bei einer Anordnung der brückenartig ausgebildeten Stelle unmittelbar hinter der Schuppenbildungsstation kann ein Träger vorgesehen werden, in welchem die die Pressbänder führenden Antriebs- und/oder Führungsmittel gelagert sind. Der Träger kann einendig am Maschinengestell befestigt sein, so dass er ein auskragendes Bauteil des Maschinengestells darstellt. In diesem Fall braucht der Träger an seinem zweiten Ende nicht zusätzlich abgestützt zu werden.In an advantageous development, the bridge-like location of the machine frame is located directly behind the scale formation station. With such an arrangement, the press belts following the scale formation station advantageously initially rise in order to then reach a height which allows sufficient free space in the adjoining area. In the case of an arrangement of the bridge-like point directly behind the scale formation station, a carrier can be provided in which the drive and / or guide means guiding the press belts are mounted. The carrier can be attached at one end to the machine frame, so that it represents a projecting component of the machine frame. In this case, the support does not need to be additionally supported at its second end.

In einer bevorzugten Ausführungsform reicht der Freiraum bis auf die Ebene, auf welcher die Verpressvorrichtung aufgebaut ist. Im Regelfall ist dieses der Boden einer Werkshalle, der sowohl die Schuppenbildungsstation, die Verpressvorrichtung und die Sackstapelstation trägt. Das untere Ende des Freiraums ist also insbesondere nicht durch Bauteile des Maschinengestells begrenzt.In a preferred embodiment, the free space extends to the level on which the pressing device is constructed. As a rule, this is the floor of a factory hall, which carries both the scale formation station, the pressing device and the bag stacking station. The lower end of the free space is therefore in particular not limited by components of the machine frame.

Eine besonders bevorzugte Ausführungsform der Erfindung weist einen Freiraum auf, der in der Transportrichtung der Säcke ein Maß von mindestens 500mm aufweist. Dieses Maß stellt eine Durchgangsbreite des Freiraums dar, bei der das Bedienpersonal sehr einfach die Bedienseite wechseln kann.A particularly preferred embodiment of the invention has a free space which has a dimension of at least 500 mm in the direction of transport of the bags. This dimension represents a passage width of the free space in which the operating personnel can change the operating side very easily.

Da auch selbst bei einer großen Durchgangsbreite ein Kontakt des Bedienpersonals mit sich bewegenden Maschinenteilen nicht ausgeschlossen werden kann, ist in einer bevorzugten Ausgestaltung der Erfindung eine Trenneinrichtung zwischen dem Freiraum und dem Maschinengestell vorgesehen. Diese Trenneinrichtung kann durch Bleche gebildet werden. Um die Sicht auf die Maschinenteile und die zu verpressenden Säcke zu ermöglichen, kann diese Trenneinrichtung auch aus einem Gitter oder Plexiglasscheiben bestehen.Since even with a large passage width, contact of the operating personnel with moving machine parts cannot be ruled out, a separating device between the free space and the machine frame is provided in a preferred embodiment of the invention. This separating device can be formed by sheets. In order to allow a view of the machine parts and the bags to be pressed, this separating device can also consist of a grid or plexiglass panes.

Vorteilhaft ist es, wenn der Freiraum zwischen der Schuppenbildungsstation und einer Einrichtung zur Umlenkung des aus den geschuppt übereinander angeordnetenSäcken bestehenden Schuppenstroms, in welcher der Schuppenstrom um mindestens 120° umgelenkt wird, angeordnet ist. Eine solche Einrichtung zur Umlenkung des Schuppenstroms besteht in der Regel aus einem Presszylinderpaar. Entlang der Oberflächen dieser Presszylinder beschreiben die Säcke, wie eingangs erläutert, einen in etwa S-förmigen Weg. Um diese starke Verpressung über eine ausreichend lange Zeit aufrecht zu erhalten, werden die Säcke über einen Winkel von mindestens 120° über jeden Presszylinder geführt. Eine solche Einrichtung zur Umlenkung des Schuppenstroms kann allerdings auch mit einer Vielzahl von Walzen relativ kleinen Durchmessers realisiert sein. Die Walzen sind dabei so angeordnet, dass die Säcke ebenfalls entlang eines S-förmigen Wegs gefördert und dabei stark verpresst werden.It is advantageous if the free space is arranged between the scale formation station and a device for deflecting the scale flow consisting of the shingled sacks, in which the scale flow is deflected by at least 120 °. Such a device for deflecting the scale flow usually consists of a pair of press cylinders. As explained at the beginning, the bags describe an approximately S-shaped path along the surfaces of these press cylinders. In order to maintain this strong compression for a sufficiently long time, the bags are at an angle of at least 120 ° over each press cylinder. Such a device for deflecting the scale flow can, however, also be implemented with a large number of rollers of relatively small diameter. The rollers are arranged in such a way that the bags are also conveyed along an S-shaped path and are strongly compressed in the process.

Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor. Die einzige Figur zeigt eine Seitenansicht der erfindungsgemäßen Verpressvorrichtung.Further exemplary embodiments of the invention are evident from the description and the claims. The single figure shows a side view of the pressing device according to the invention.

Die Figur zeigt eine Verpressvorrichtung 1 für mit geklebten Böden versehene Säcke. Diese Säcke werden zunächst der Schuppenbildungsstation 2 in der Transportrichtung A zugeführt und auf allgemein bekannte und daher nicht näher beschriebene Weise schuppenförmig angeordnet. Nach der Schuppenbildung werden die Säcke von zwei übereinander liegenden Pressbändern 3 übernommen, wobei die Sackböden zwischen den Pressbändern 3 klemmend gefördert werden. In der Figur sind die doppelt übereinander gelegten Pressbänder 3 der Einfachheit halber nur als eine einzige Linie dargestellt. Die Pressbänder 3 werden über nicht dargestellte Rollen oder Walzen, welche im Maschinengestell 4 gelagert sind, geführt beziehungsweise angetrieben. Auf dem Weg durch die Verpressvorrichtung 1 werden die Pressbänder 3 über ein Paar von Presszylindern 5, 6 geführt. In dem gezeigten Ausführungsbeispiel umschlingen die Pressbänder 3 jeden der Presszylinder um mindestens 180°. Nachdem die Säcke die Presszylinder 5, 6 passiert haben, gelangen sie zur Sackstapelstation 7, in der die nun fertig hergestellten Säcke stapelweise angeordnet werden. Die Sackstapel können von dort abtransportiert werden.The figure shows a pressing device 1 for bags provided with glued bottoms. These bags are first fed to the scale formation station 2 in the transport direction A and arranged in a scale-like manner in a generally known and therefore not described manner. After the formation of flakes, the bags are taken over by two press belts 3 lying one above the other, the bag bottoms between the press belts 3 being conveyed by clamping. For the sake of simplicity, the press belts 3, which are placed twice over one another, are shown in the figure only as a single line. The press belts 3 are guided or driven via rollers or rollers, not shown, which are mounted in the machine frame 4. On the way through the pressing device 1, the press belts 3 are guided over a pair of press cylinders 5, 6. In the exemplary embodiment shown, the press belts 3 loop around each of the press cylinders by at least 180 °. After the sacks have passed the press cylinders 5, 6, they arrive at the sack stacking station 7, in which the sacks which have now been produced are arranged in stacks. The stacks of bags can be removed from there.

Im Bereich 8 zwischen Schuppenbildungsstation und den Presszylindern 5, 6 sind die Pressbänder 3 ansteigend angeordnet. Im Bereich dieses Anstieges, den die Pressbänder 3 durchlaufen, ist das Maschinengestell 4 brückenartig ausgebildet, so dass unter dem Maschinengestell 4 ein Freiraum 9 verbleibt. Dieser Freiraum 9 bietet einen Durchgang für das Bedienpersonal der Maschine, so dass dieses von der einen auf die andere Seite der Verpressvorrichtung 1 gelangen kann. Der Freiraum 9 ist durch eine Trenneinrichtung 10 von der Verpressvorrichtung 1 abgeteilt, so dass ein unbeabsichtigtes Hineingreifen in die Vorrichtung seitens des Bedienpersonals verhindert wird. In the area 8 between the scale formation station and the press cylinders 5, 6, the press belts 3 are arranged to rise. In the area of this rise, through which the press belts 3 pass, the machine frame 4 is designed in a bridge-like manner, so that a free space 9 remains under the machine frame 4. This free space 9 provides a passage for the operating personnel of the machine, so that it can get from one side to the other side of the pressing device 1. The free space 9 is separated from the pressing device 1 by a separating device 10, so that unintentional reaching into the device by the operating personnel is prevented.
