Description

Vorrichtung zur Herstellung von Säcken aus schlauchförmigem Material Apparatus for producing bags of tubular material
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Säcken aus schlauchförmigem Material, welches Gewebe aus gerecktenThe invention relates to a device for producing sacks of tubular material, which fabric from stretched
Kunststoffbändchen umfasst, nach dem Oberbegriff des Anspruchs 1 , und ein Verfahren zur Herstellung von Säcken nach dem Oberbegriff des Anspruchs 13.Plastic tape comprises, according to the preamble of claim 1, and a method for producing sacks according to the preamble of claim 13.
Solche Vorrichtungen sind bekannt und schon längere Zeit am Markt erhältlich. Diese Vorrichtungen umfassen in der Regel zunächst eine Schlauchbildungsvorrichtung zur Herstellung und Bereitstellung eines schlauchförmigen Materials. Es kann auch lediglich eine Schlauchabwickelvorrichtung vorhanden sein. Diese ist in der Regel mit einem Materialwickel bestückbar, auf welchem schlauchförmiges Material gewickelt ist. Von diesem Materialwickel wird das Material meist kontinuierlich in Längsrichtung abgezogen.Such devices are known and have been available on the market for a long time. These devices typically include a tube forming apparatus for making and providing a tubular material. It may also be present only a Schlauchabwickelvorrichtung. This is usually equipped with a material wrap on which tubular material is wound. From this material wrap the material is usually withdrawn continuously in the longitudinal direction.
Beim Sackherstellungsprozess nach den Maschinen des Standes der Technik wird der durch die Schlauchbildungsvorrichtung oder der durch die Schlauchabwickelvorrichtung bereitgestellte Gewebeschlauch der Querschneideeinrichtung zugeführt, die den Gewebeschlauch in einzelne Schlauchstücke vereinzelt. Die Schlauchstücke werden einer Transporteinrichtung übergeben. Mithilfe dieser Transporteinrichtung erfolgt eine Änderung der ursprünglichen Transportrichtung, in der der Schlauch bzw. die Schlauchstücke in Richtung ihrer Längsachsen transportiert wurden, in eine neue Transportrichtung, so dass die Schlauchstücke nun nicht mehr in Richtung ihrer Schlauchlängsachse, sondern quer hierzu transportiert werden, so dass die Enden der Schlauchstücke zwecks Anformung der Böden seitlich erreichbar sind. Die ursprüngliche und die neue Transportrichtung des Schlauchs bzw. des Schlauchstücks liegen dabei senkrecht zueinander.In the sack manufacturing process of the prior art machines, the fabric hose provided by the hose forming apparatus or by the hose unwinding apparatus is fed to the cross cutter, which separates the fabric hose into individual pieces of hose. The pieces of hose are transferred to a transport device. By means of this transport device, a change of the original transport direction, in which the tube or pieces of tubing were transported in the direction of their longitudinal axes, takes place in a new transport direction, so that the tube pieces are no longer transported in the direction of their tube longitudinal axis, but transversely thereto, so that the ends of the hose pieces for the purpose of Anformung the floors laterally accessible are. The original and the new transport direction of the hose or hose piece are perpendicular to each other.
Wie bereits erwähnt, wird das schlauchförmige Gewebematerial, das zudem beschichtet sein kann, zu Schlauchstücken vereinzelt. Bei der Schlauchstückherstellung wird der Schlauch in seiner Längsrichtung taktweise jeweils um eine Schlauchstücklänge vorgezogen. Um das taktweise Vorziehen zu ermöglichen, ist zwischen dem Materialwickel und der Vereinzelungsvorrichtung eine Ausgleichseinrichtung in Form von mindestens einer beweglichen Umlenkstange vorgesehen. Anschließend wird ein Schlauchstück von dem Schlauch vereinzelt, also abgetrennt. Dieses erfolgt in der Regel mit einem Schneidwerkzeug wie einem Messer. Jedoch sind auch andere Abtrennverfahren und die zugehörigen Einrichtungen denkbar. Der genannte Materialwickel umfasst oft einen Gewebeschlauch, der aus rundgewebtem Material besteht. Der auf einem Rundwebstuhl erzeugte Schlauch wird nach seiner Herstellung flachgelegt und mit einer Beschichtung versehen, welche sicherstellt, dass Teile des Schlauchstücks miteinander verschweißt werden können, ohne dass das gereckte Gewebe Schaden nimmt und seine Festigkeit einbüßt.As already mentioned, the tubular fabric material, which may also be coated, is singulated into pieces of tubing. In the manufacture of tubing, the tubing is progressively advanced in its longitudinal direction by one length of tubing. To enable the cyclic advancing, a compensation device in the form of at least one movable deflection bar is provided between the material winding and the separating device. Subsequently, a piece of hose is separated from the hose, so separated. This is usually done with a cutting tool such as a knife. However, other separation methods and the associated facilities are conceivable. Said material wrap often comprises a fabric tube made of a circular woven material. The tube produced on a round loom is flattened after its manufacture and provided with a coating, which ensures that parts of the hose piece can be welded together without the stretched fabric being damaged and losing its strength.
Die Schlauchbildungsvorrichtung formt schlauchförmiges Material, indem die Ränder der Materialbahn aufeinander gelegt und miteinander, beispielsweise mittels eines Kunststoffextrudats, verbunden werden. Bei diesem Prozess werden sowohl die flache Materialbahn als auch der Schlauch in Längsrichtung transportiert. Das schlauchförmige Material besteht aus zwei übereinander liegenden Materialbahnen, welche jeweils aus mehreren Schichten bestehen können. Die genannte Schlauchbildungsvorrichtung kann zusätzlich in der Lage sein, Seitenfalten einzulegen. Mit Seitenfalten versehene Säcke weisen Vorteile auf, wenn sie im befüllten Zustand gestapelt werden sollen. Die Herstellung von Schläuchen aus gewebtem und beschichtetem Flachmaterial hat den großen Vorteil, dass kein Beschichtungsmatehal seitlich über den Rändern des flachen Schlauches übersteht, wie es oft der Fall ist, wenn flachgelegtes, rundgewebtes Schlauchmaterial beschichtet wird. Überstehendes Beschichtungsmaterial führt häufig zu Fehlern bei der Herstellung von Säcken aus Stücken des Schlauchmaterials.The hose forming apparatus forms tubular material by stacking the edges of the web of material and joining them together, for example by means of a plastic extrudate. In this process, both the flat web and the hose are transported in the longitudinal direction. The tubular material consists of two superimposed material webs, which may each consist of several layers. The said hose-forming device may additionally be capable of inserting gussets. Gusseted bags have advantages when stacked when filled. Producing hoses made of woven and coated sheet material has the great advantage that no coating matehal projects laterally beyond the edges of the flat hose, as is often the case when flat laid, round-woven hose material is coated. Supernatant coating material leads often errors in the manufacture of bags from pieces of tubing.
Das auf die beschriebene Weise erzeugte Schlauchstück wird von zumindest einer Transportvorrichtung übernommen, um sie in die einzelnenThe piece of hose produced in the manner described is taken over by at least one transport device in order to place them in the individual
Bearbeitungsstationen zu verbringen. Nach dem Abtrennen werden dieSpend processing stations. After disconnecting, the
Schlauchstücke nicht mehr in Längsrichtung weiter transportiert, sondern inHose pieces no longer transported in the longitudinal direction, but in
Querrichtung. Mit „Querrichtung" ist gemeint, dass die Schlauchstücke nunmehr quer zu ihrer Längserstreckung transportiert werden, um bei den weiteren Schritten zur Herstellung von Säcken ungehinderten Zugang zu beiden Enden der Schlauchstücke zu erhalten.Transverse direction. By "transverse direction" it is meant that the pieces of tubing are now transported transversely to their longitudinal extent so as to obtain unimpeded access to both ends of the pieces of tubing in the further steps of making bags.
Im Folgenden werden einzelne Stationen bei der Sackherstellung aufgeführt und deren Funktion erläutert:In the following, individual stations are listed during bag making and their function is explained:
• In einer fakultativ vorhandenen Vorbruchstation werden Formstempel zur Erzeugung einer Falzlinie auf das Schlauchstück abgesenkt. Auf dieser Falzlinie befinden sich später die Eckeinschläge des geöffneten Schlauchbodens. Die Formstempel können zu diesem Zweck auch beheizt werden.• In a pre-breaking station that is available as an option, forming dies are lowered onto the piece of hose to create a fold line. On this fold line are later the corner impacts of the open tube bottom. The dies can also be heated for this purpose.
• In der Bodenöffnungsstation wird zumindest ein Ende eines Schlauchstücks aufgezogen, so dass an diesem aufgezogenen Ende ein Boden angeformt werden kann. Die Eckeinschläge befinden sich auf den Falzlinien des Schlauchstücks. Aufgrund ihrer geometrischen Form wird die Bodenöffnung auch Bodenöffnungsquadrat genannt. Dabei sei angemerkt, dass die Form nicht quadratisch, sondern in den meisten Fällen rechteckig ist. In der Regel werden beide Enden eines Schlauchstücks auf die gleiche Weise bearbeitet.In the bottom opening station, at least one end of a piece of hose is pulled open, so that a bottom can be formed on this pulled-up end. The corner stops are located on the fold lines of the hose section. Due to its geometric shape, the bottom opening is also called floor opening square. It should be noted that the shape is not square, but in most cases rectangular. In general, both ends of a piece of hose are processed in the same way.
• In der Ventilzettelstation wird ein Ventilzettel auf den zuvor geöffneten Boden des Schlauchstücks gelegt. Durch den Ventilzettel kann später der fertige Sack mit Hilfe eines geeigneten Füllstutzens befüllt werden.• In the valve dispensing station, a valve leaflet is placed on the previously opened bottom of the tube piece. Through the valve leaflet, the finished bag can later be filled with the aid of a suitable filler neck.
• In einer so genannten Zulegestation werden Teile der Bodenöffnungen bzw. der Bodenöffnungsquadrate, die so genannten Laschen, beidseitig zur Falzkante hin zurückgefaltet. Dabei können Bereiche dieser Laschen überlappen, und diese überlappenden Bereiche dieser Laschen können miteinander verbunden werden. • Anschließend wird in der Bodendeckblattstation ein Bodendeckblatt mit der zugefalteten Bodenöffnung befestigt, beispielsweise verschweißt.• In a so-called feeding station, parts of the bottom openings or the bottom opening squares, the so-called tabs, are folded back on both sides towards the folded edge. It can areas of these tabs overlap, and these overlapping areas of these tabs can be interconnected. • Subsequently, a ground cover sheet with the folded bottom opening is fastened in the ground cover sheet station, for example welded.
Es ist zu erwähnen, dass nicht alle der aufgezählten Stationen in einer Vorrichtung zur Herstellung von Säcken vorhanden sein müssen. So kann auf eine Vorbruchstation verzichtet werden. Auch Bodendeckblätter müssen nicht immer aufgebracht werden, um einen Sack zu fertigen. Gleichwohl sind weitere Stationen denkbar.It should be noted that not all of the enumerated stations must be present in a sack making apparatus. So can be dispensed with a pre-break station. Even ground cover sheets do not always have to be applied to make a sack. Nevertheless, further stations are conceivable.
Wie oben bereits erwähnt, wird beim Sackherstellungsprozess bei an sich bekannten Sackherstellungsvorrichtungen der durch dieAs already mentioned above, in the sack-making process in sack-making apparatuses known per se, the method described by US Pat
Schlauchbildungsvorrichtung bereitgestellte Gewebeschlauch der Querschneideeinrichtung zugeführt, die den Gewebeschlauch in einzelne Schlauchstücke vereinzelt. Die Schlauchstücke werden einer Transporteinrichtung übergeben. Mithilfe dieser Transporteinrichtung erfolgt eine Änderung der ursprünglichen Transportrichtung, in der der Schlauch bzw. die Schlauchstücke in Richtung ihrer Längsachsen transportiert wurden, in eine neue Transportrichtung, so dass die Schlauchstücke nun nicht mehr in Richtung ihrer Schlauchlängsachse, sondern quer hierzu transportiert werden, so dass die Enden der Schlauchstücke zwecks Anformung der Böden seitlich erreichbar sind. Die ursprüngliche und die neue Transportrichtung des Schlauchs bzw. des Schlauchstücks liegen dabei senkrecht zueinander. Aus diesem Grund sind auch die Schlauchbildungsvorrichtung und die oben erwähnten Bearbeitungsstationen senkrecht zueinander angeordnet bzw. aufgebaut.Tube forming device supplied fabric tube of the cross cutter, which singles the fabric tube into individual pieces of hose. The pieces of hose are transferred to a transport device. By means of this transport device, a change of the original transport direction, in which the tube or pieces of tubing were transported in the direction of their longitudinal axes, takes place in a new transport direction, so that the tube pieces are no longer transported in the direction of their tube longitudinal axis, but transversely thereto, so that the ends of the hose pieces are laterally accessible for the purpose of molding the floors. The original and the new transport direction of the hose or hose piece are perpendicular to each other. For this reason, the tube forming apparatus and the above-mentioned processing stations are also arranged perpendicular to each other.
Die senkrechte Anordnung der Schlauchbildungsvorrichtung zu den Bearbeitungsstationen ist nachteilig. Die Grundfläche von Produktionshallen ist in der Regel rechteckig und daher ist eine solche Anordnung Platz raubend.The vertical arrangement of the hose forming device to the processing stations is disadvantageous. The floor space of production halls is usually rectangular and therefore such an arrangement is space consuming.
Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Herstellung von Säcken aus schlauchförmigem Material vorzuschlagen, die Platz sparender aufgebaut werden kann. Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils der Ansprüche 1 und 13 gelöst.The object of the present invention is therefore to propose a device for the production of bags of tubular material, which can be constructed to save space. According to the invention, this object is solved by the features of the characterizing part of claims 1 and 13.
Demnach sind die Transportrichtungen des schlauchförmigen Materials in der Schlauchbildungsvorrichtung und der Schlauchstücke in der Transporteinrichtung parallel zueinander ausgerichtet. „Parallel" kann dabei umfasst werden, dass die Transportrichtungen einander entgegengesetzt oder auch gleichgerichtet sind. Der erstgenannte Fall ist interessant, falls eine lang gestreckte, schmale Werkhalle zur Verfügung steht. Der an zweiter Stelle genannte Fall bietet sich für eher breite, aber dafür kurze Werkhallen an. „Parallel" meint zudem die horizontale Komponente der Bewegungsrichtung. Eine vertikale Bewegungskomponente bleibt davon unberührt.Thus, the transporting directions of the tubular material in the hose forming device and the hose pieces in the transporting device are aligned parallel to each other. "Parallel" can be understood to mean that the directions of transport are opposite or even rectilinear.The former case is interesting if an elongated, narrow workshop is available.The second case is more broad but short In addition, "horizontal" means the horizontal component of the direction of movement. A vertical component of motion remains unaffected.
Die Schlauchbildungsvorrichtung fördert das schlauchförmige Material entlang der Schlauchlängsachse. Da die Bearbeitungsstationen die Enden der einzelnen Schlauchstücke erreichen müssen, ist es vorteilhaft, die Schlauchstücke quer zur Längsachse zu den Bearbeitungsstationen zu transportieren. Daher ist es besonders vorteilhaft, wenn zumindest eine Umlenkvorrichtung zwischen der Schlauchbildungsvorrichtung und der Bodenbildungsvorrichtung vorgesehen ist, mit welcher das schlauchförmige Material vor der Querschneidung in eine neue Transportrichtung umlenkbar ist, welche sich zumindest teilweise quer zur ursprünglichen Transportrichtung erstreckt. Damit kann der Schlauch bereits in die Richtung gefördert werden, die der Lage der Schlauchstücke entspricht, die für die spätere Bearbeitung der Schlauchstücke notwendig ist. Im Gegensatz hierzu wäre es möglich, den Schlauch in Transportrichtung zu Schlauchstücken zu vereinzeln und diese Schlauchstücke einzeln oder im Paket zu drehen, was allerdings aufwändig und damit teuer im Vergleich zu der erfinderischen Lösung ist. Der umgelenkte Schlauch kann anschließend in einzelne Schlauchstücke vereinzelt werden, die den Bearbeitungsstationen nun in einer Bewegungsrichtung quer zu ihrer Längsachse zugeführt werden. Auch eine Schlauchabwickelvorrichtung kann gemäß der genannten Erfindung angeordnet werden. Eine besonders bevorzugte Ausgestaltung der Erfindung beinhaltet, dass die Umlenkvorrichtung, mit der das schlauchförmige Material umlenkbar ist, in ihrer Position veränderbar, insbesondere in der ursprünglichen Transportrichtung des schlauchförmigen Materials verschiebbar ist. Dies hat den Vorteil, dass die Kantenlage unterschiedlich breiter Materialschläuche an die Querschneideoder Vereinzelungsvorrichtung angepasst werden kann. Insbesondere bei Schläuchen, die in einer Schlauchbildungsvorrichtung erzeugt werden, ist die Mittellage, unabhängig von der Schlauchbreite, meist gleich. Von der Transporteinrichtung werden die Schlauchstücke jedoch an ihrer vorderen Seitenkante erfasst, so dass nicht die Mittellinie, sondern die Vorderkante, unabhängig von der Schlauchbreite, eine konstante Position einnehmen muss. Dies wird besonders einfach durch die Verschiebbarkeit der Umlenkvorrichtung erreicht. Gleichwohl ist denkbar, dass mehrere Umlenkelemente vorgesehen sind, die in ihrem Neigungswinkel relativ zur Transportrichtung der Schlauchbahn veränderbar sind. Auch auf diese Weise kann die Position der Vorderkante angepasst werden.The hose forming device conveys the tubular material along the tube longitudinal axis. Since the processing stations have to reach the ends of the individual tube pieces, it is advantageous to transport the tube pieces transversely to the longitudinal axis to the processing stations. Therefore, it is particularly advantageous if at least one deflecting device is provided between the hose forming device and the bottom forming device, with which the tubular material is deflected before the transverse cutting in a new transport direction, which extends at least partially transverse to the original transport direction. Thus, the hose can be conveyed already in the direction corresponding to the position of the hose pieces, which is necessary for the subsequent processing of the hose pieces. In contrast, it would be possible to singulate the tube in the transport direction into pieces of tubing and to rotate these pieces of tubing individually or in a package, which is, however, complicated and thus expensive compared to the inventive solution. The deflected tube can then be separated into individual pieces of tubing, which are then fed to the processing stations in a direction of movement transverse to their longitudinal axis. A hose unwinding device may also be arranged according to the invention. A particularly preferred embodiment of the invention includes that the deflection device, with which the tubular material is deflected, in its position variable, in particular in the original transport direction of the tubular material is displaceable. This has the advantage that the edge layer of different widths of material hoses can be adapted to the cross-cutting or separating device. Especially with hoses that are produced in a hose-forming device, the middle layer, regardless of the hose width, is usually the same. By the transport device, however, the hose pieces are detected on its front side edge, so that not the center line, but the leading edge, regardless of the hose width, must assume a constant position. This is achieved particularly easily by the displaceability of the deflection device. Nevertheless, it is conceivable that a plurality of deflection elements are provided, which are variable in their inclination angle relative to the transport direction of the tubular web. Also in this way, the position of the leading edge can be adjusted.
Bei der Umlenkvorrichtung kann es sich vorteilhafterweise um eine an sich bekannten Luftwendestange handeln. Die Luftwendestange kann Bohrungen enthalten, die mit Luft beaufschlagt werden, so dass das schlauchförmige Material berührungslos über die Wendestange geführt werden kann.The deflecting device can advantageously be a per se known air turning bar. The air turning bar may include holes that are exposed to air, so that the tubular material can be guided without contact over the turning bar.
In einer bevorzugten Ausführungsform der Erfindung sind die Vereinzelungsvorrichtung und die Umlenkvorrichtung vertikal voneinander beabstandet. Bevorzugt ist dabei die Umlenkvorrichtung oberhalb der Vereinzelungsvorrichtung angeordnet. Die Umlenkvorrichtung kann aber auch unterhalb der Vereinzelungsvorrichtung positioniert sein. Dadurch ist es möglich, dass die Schlauchbereitstellungsvorrichtung und die weiteren Schlauchstück-Bearbeitungsstationen direkt hintereinander - in einer Linie - aufgebaut bzw. angeordnet werden können. In diesem Fall befinden sich auch die geometrische Schlauch- und Schlauchstückmittellinie in einer Linie, was ebenfalls unnötigen Platzverbrauch vermeidet. Vor allem ist es dadurch möglich, dass die Transportrichtung des Schlauchs mittels nur einer, in Transportrichtung des Schlauches schräg angeordneter, Umlenkvorrichtung verändert wird. Besonders vorteilhaft ist es, wenn die Umlenkvorrichtung oberhalb der Vereinzelungsvorrichtung angeordnet ist. Mittels Transportwalzen, deren Drehachsen quer zur Transportrichtung des Schlauches angeordnet sind, kann letztere auf die Ebene der Vereinzelungsvorrichtung geleitet werden.In a preferred embodiment of the invention, the separating device and the deflection device are vertically spaced from each other. Preferably, the deflection device is arranged above the separating device. However, the deflection device can also be positioned below the separating device. This makes it possible for the hose delivery device and the further hose piece processing stations to be constructed or arranged directly one behind the other - in a line. In this case, the geometric hose and hose center line are in line, which also avoids unnecessary space consumption. Above all, it is possible that the transport direction of the tube by means of only one, in the transport direction of the tube obliquely arranged deflecting device is changed. It is particularly advantageous if the deflecting device is arranged above the separating device. By means of transport rollers whose axes of rotation are arranged transversely to the transport direction of the tube, the latter can be passed to the level of the separating device.
In einer weiteren bevorzugten Ausführungsform der Erfindung umfasst die Schlauchbildungsvorrichtung eine Speichervorrichtung, welche in Transportrichtung des Schlauches vor der Umlenkeinrichtung angeordnet ist. Mit der Speichervorrichtung ist schlauchförmiges Material, welches zuvor durch die Schlauchbildungsvorrichtung erzeugt wurde, speicherbar. So können beispielsweise bei einer Fehlfunktion der Schlauchbildungssvorrichtung oder bei einem Materialwickelwechsel die einzelnen Bearbeitungsstationen (insbesondere die Schlauchvereinzelungsvorrichtung) weiter mit schlauchförmigem Material versorgt werden, ohne dass die Sackproduktion gestoppt werden muss. Auch kann, in gewissen Grenzen, weiteres Schlauchmaterial gespeichert werden, wenn die Bearbeitungsstationen angehalten werden müssen.In a further preferred embodiment of the invention, the hose-forming device comprises a storage device which is arranged in the transport direction of the hose in front of the deflection device. With the storage device, tubular material previously generated by the tube forming device is storable. Thus, for example, in the event of a malfunction of the hose-forming device or during a material-winding change, the individual processing stations (in particular the hose-separating device) can be further supplied with tubular material without the sack production having to be stopped. Also, within certain limits, further tubing can be stored when the processing stations need to be stopped.
In einer weiteren vorteilhaften Ausführungsform umfasst die Schlauchbildungsvorrichtung eine Aufwicklung, mit welcher das zuvor hergestellte schlauchförmige Material zu einem Wickel aufgewickelt werden kann. Die Schlauchbildungsvorrichtung kann „offline" - das heißt ohne Zuführung von schlauchförmigem Material an die Bearbeitungsstationen - arbeiten.In a further advantageous embodiment, the hose-forming device comprises a winding with which the previously prepared tubular material can be wound into a winding. The tube forming apparatus can operate "offline" - that is, without supplying tubular material to the processing stations.
Im „Offline-Betrieb" können die Bearbeitungsstationen auch von einer Abwickelvorrichtung mit schlauchförmigem Material gespeist werden. Die Abwickelvorrichtung umfasst einen Wickel aus schlauchförmigem Material und ist nicht mit der Schlauchbildungsvorrichtung verbunden. Der Materialwickel kann zuvor von der Schlauchbildungsvorrichtung produziert worden sein.The unwinding device comprises a coil of tubular material and is not connected to the hose forming device The material coil may have previously been produced by the hose forming device.
Die Vorrichtung zur Herstellung von Säcken kann demnach in zwei alternativen Arbeitsweisen betrieben werden. Im so genannten „Inline-Betrieb" wird die Querschneidevorrichtung direkt mit schlauchförmigem Material von der Schlauchbildungsvorrichtung versorgt. Im „Offline-Betrieb" wird die Vorrichtung zur Herstellung von Säcken - wie oben bereits beschrieben - von einem separaten Schlauchmaterialwickel versorgt, der in der beschriebenen Weise von der Schlauchbildungsvorrichtung erzeugt werden kann. Auf diese Weise können die genannten Bestandteile der Vorrichtung zur Herstellung von Säcken mit größtmöglicher Flexibilität betrieben werden. Diese Flexibilität ist beispielsweise bei Wartungsarbeiten an einzelnen Bestandteilen der Vorrichtung zur Herstellung von Säcken besonders gefordert.The device for producing sacks can therefore be operated in two alternative ways of working. In the so-called "in-line operation", the cross-cutting device is used directly with tubular material from the Hose forming device supplied. In "off-line" operation, as described above, the sack making apparatus is supplied by a separate tubing reel that can be produced by the hose forming apparatus in the manner described This flexibility is particularly required, for example, for maintenance work on individual components of the device for producing sacks.
In einer weiteren bevorzugten Ausführungsform umfasst die Schlauchbereitstellungsvorrichtung eine Vorrichtung zurIn a further preferred embodiment, the hose delivery device comprises a device for
Materialfehlererkennung. Durch die Vorrichtung zur Materialfehlererkennung sind fehlerhafte Schlauchbereiche erkennbar. Bei den fehlerhaften Schlauchbereichen kann es sich um undichte Nahtstellen handeln. Diese können beispielsweise bei einer fehlerhaften Verklebung der Materialbahnränder in der Schlauchbildungsvorrichtung entstehen. Fehlerhafte Schlauchbereiche können aber auch Gewebefehler oder Beschichtungsfehler des flachen Materials sein, welches zum schlauchförmigen Material gefertigt wird. Auch eine falsche Schlauchbreite kann als fehlerhafter Schlauchbereich erkannt werden.Material error detection. Due to the device for material defect detection faulty hose areas are recognizable. The faulty hose areas can be leaky seams. These may arise, for example, in the case of faulty bonding of the material web edges in the hose forming device. However, defective hose areas can also be fabric defects or coating defects of the flat material, which is made into a tubular material. Even a wrong hose width can be recognized as a defective hose area.
Vorteilhaft ist, wenn in Transportrichtung des schlauchförmigen Materials hinter der Schlauchvereinzelungsvorrichtung eine Ausscheideweiche vorgesehen ist. Mit dieser Ausscheideweiche können Schlauchstücke, die fehlerhafte Bereiche aufweisen, ausgeschleust werden.It is advantageous if, in the transport direction of the tubular material, a separation separator is provided behind the tube separating device. With this separating softener pieces of hose, which have faulty areas, can be discharged.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist eine Steuervorrichtung vorgesehen, der über eine geeignete Datenleitung Daten von der Vorrichtung zur Materialfehlererkennung zuleitbar sind. Bei diesen Daten handelt es sich um Informationen zu den oben beschriebenen fehlerhaften Bereichen des schlauchförmigen Materials. Die Vorrichtung zur Materialfehlererkennung ist vorteilhafterweise vor der Vereinzelungsvorrichtung angeordnet. Hinter der Vereinzelungsvorrichtung befindet sich vorteilhafterweise direkt die Ausscheideweiche.In a further advantageous embodiment of the invention, a control device is provided, which can be supplied via a suitable data line data from the device for material defect detection. This information is information about the defective areas of the tubular material described above. The device for detecting material defects is advantageously arranged in front of the separating device. Behind the separating device is advantageously located directly the separation.
Vorteilhafterweise wird die Ausscheideweiche von der Steuervorrichtung aktiviert, wenn die Vorrichtung zur Materialfehlererkennung einen fehlerhaften Bereich erkannt (und dies der Steuereinheit übermittelt) hat und der betreffende Schlauchabschnitt vereinzelt wurde. Anstelle der Transportvorrichtung übernimmt nun die Ausscheideweiche den Schlauchabschnitt. In diesem Fall wird das fehlerhafte Schlauchstück ausgeschleust, bevor es zu den einzelnen Bearbeitungsstationen gelangen und zum Sack verarbeitet werden kann. Mit dieser rechtzeitigen Ausschleusung fehlerhafter Schlauchstücke kann daher viel Energie und Zeit eingespart werden, da fehlerhafte Schlauchstücke nicht erst zum Sack verarbeitet werden.Advantageously, the Ausscheideweiche is activated by the control device, when the device for material defect detection detected a defective area (and this the control unit transmitted) and the respective tube section has been singled. Instead of the transport device now takes the elimination separator the hose section. In this case, the defective piece of hose is discharged before it can reach the individual processing stations and can be processed into a sack. With this timely discharge defective hose pieces can therefore be saved a lot of energy and time, because faulty hose pieces are not processed until the bag.

Die Schlauchbildungsvorrichtung 13 umfasst einen Wickel 3, der bahnförmiges Material 14 enthält. Das bahnförmige Material 14 wird in Transportrichtung x' einem Schlauchbildungsbereich 28 zugeführt. Hier 28 wird das bahnförmige Material in bekannter Weise auf sich selbst zurückgefaltet und die Kanten miteinander verklebt oder verschweißt, so dass ein Materialschlauch 2 entsteht. Anschließend erfährt der Schlauch 2 die so genannte Öffnung in der Öffnungsstation 5. Dabei wird der Gewebeschlauch um ein Innenwerkzeug herum geführt, welches die beiden Lagen voneinander trennt, so dass sich die Lagen, falls sie bei einem der Herstellungsschritte des Schlauches 2 miteinander verklebt wurden, trennen. Nur bei getrennten Lagen kann sichergestellt werden, dass die folgenden Produktionsschritte ordnungsgemäß durchgeführt werden können. Im Anschluss werden die voneinander getrennten Materiallagen des Schlauches 2 wieder aufeinander gelegt.The tube forming device 13 comprises a coil 3 containing sheet material 14. The web-shaped material 14 is fed in the transport direction x 'a hose forming portion 28. Here, the web-shaped material is folded back on itself in a known manner and the edges glued or welded together, so that a material tube 2 is formed. Subsequently, the tube 2 undergoes the so-called opening in the Opening station 5. The fabric hose is guided around an inner tool around which separates the two layers, so that the layers, if they were glued together in one of the manufacturing steps of the tube 2, separate. Only with separate layers can it be ensured that the following production steps can be carried out properly. Subsequently, the separate material layers of the tube 2 are placed again on each other.
Im weiteren Transportverlauf wird die schlauchförmige Materialbahn 2 einer Umlenkvorrichtung, vorzugsweise zumindest einer Wendestange 17, zugeführt.In the further course of transport, the tubular material web 2 is a deflection device, preferably at least one turning bar 17, supplied.
Die Wendestange 17 ist in Richtung des Doppelpfeils 15 verschiebbar. Mithilfe der Wendestange 17 wird der Materialschlauch 2 aus der ursprünglichenThe turning bar 17 is displaceable in the direction of the double arrow 15. By means of the turning bar 17 of the material hose 2 from the original
Transportrichtung x' in die Transportrichtung y gelenkt und einerTransport direction x 'directed in the transport direction y and a
Querschneidevorrichtung 6 zugeführt, die den Gewebeschlauch in einzelne Schlauchstücke 16 vereinzelt.Cross cutting device 6 supplied, which singles the fabric tube into individual pieces of hose 16.
Anschließend werden die Schlauchstücke 16 quer zu ihrer Schlauchlängsachse in Transportrichtung x transportiert, so dass die Enden der Schlauchstücke zwecks Anformung der Böden von den betreffenden Bearbeitungsstationen seitlich erreichbar sind.Subsequently, the tube pieces 16 are transported transversely to their tube longitudinal axis in the transport direction x, so that the ends of the tube pieces for the purpose of Anformung the bottoms of the respective processing stations are laterally accessible.
Die Transportrichtung x' des schlauchförmigen Materials 2 und die Transportrichtung x des Schlauchstücks 16 verlaufen parallel.The transport direction x 'of the tubular material 2 and the transport direction x of the tube piece 16 are parallel.
Durch den parallelen Verlauf der Transportrichtung x' des schlauchförmigen Materials und x des Schlauchstücks wird erreicht, dass auch eine parallele Anordnung der Schlauchbildungsvorrichtung zu den Bearbeitungsstationen möglich ist. Dadurch ist eine sehr kompakte und Platz sparende Bauweise der Sackherstellungsvorrichtung möglich. Ebenfalls wird es durch die Parallelität der Bewegungsrichtungen x' und x möglich, die Schlauchbereitstellungsvorrichtung und die einzelnen Bearbeitungsstationen direkt hintereinander aufzustellen und so eine lange, aber schlanke Sackproduktionslinie zu erhalten. In der folgenden Station, der Bodenöffnungsstation 8, werden beide Enden eines jeden Schlauchstücks geöffnet und die so genannten Bodenquadrate gelegt. In der darauf folgenden Ventilstation 9 wird auf eines der beiden offenen Enden ein Ventil aufgelegt und befestigt. Die offenen Böden werden nun in der Bodenschließstation 10 geschlossen, wobei zwei Laschen aufeinander gelegt werden und miteinander dauerhaft, beispielsweise durch Verschweißen, verbunden werden. Den Abschluss des eigentlichen Sackherstellprozesses bildet das Aufbringen je eines Bodendeckblattes auf die Böden in der Deckblattstation 11. Dazu können die Deckblätter ebenfalls aufgeschweißt werden. Die fertigen Säcke werden anschließend auf dem Sackstapel 12 abgelegt und von dort auf nicht näher beschriebene Weise abtransportiert.By the parallel course of the transport direction x 'of the tubular material and x of the hose piece is achieved that a parallel arrangement of the hose forming device to the processing stations is possible. As a result, a very compact and space-saving design of the sack manufacturing device is possible. It is also possible by the parallelism of the directions of movement x 'and x, set up the hose delivery device and the individual processing stations directly behind each other and thus to obtain a long but slim bag production line. In the following station, the bottom opening station 8, both ends of each tube piece are opened and the so-called bottom squares are laid. In the following valve station 9, a valve is placed and secured on one of the two open ends. The open floors are now closed in the bottom closing station 10, wherein two tabs are placed on each other and permanently connected to each other, for example by welding. The conclusion of the actual Sackherstellprozesses forms the application of a ground cover sheet on the floors in the cover sheet station 11. For this purpose, the cover sheets can also be welded. The finished bags are then placed on the bag stack 12 and transported away from there on unspecified manner.
Die Figur 2 zeigt eine Draufsicht auf die Wendestange 17. Die Wendestange kann über eine Halterung 24 drehbar auf einem Halterahmen 18 befestigt sein. Der Halterahmen 18 liegt in dem hier gezeigten Ausführungsbeispiel in einer Ebene, die parallel zur Bewegungsrichtung des schlauchförmigen Materials 2 ist. Unterhalb des Halterahmens 18 sind Schlitten 20, 27 angebracht, die in Schienen 19 greifen (Figur 3). Der Halterahmen 18 ist mithilfe der Schlitten 20, 27 auf den Schienen 19 verfahrbar. Der Schlitten 27 ist in Richtung z verlängert. Am unteren Ende des verlängerten Schlittens 27 ist eine Spindelmutter eingearbeitet, in die eine Spindel 21 greift. Die Spindel 21 ist mithilfe des Motors 23 drehbar. Durch Drehung der Spindel 21 , die in die Spindelmutter der verlängerten Schlitten 27 eingreift, ist der Halterahmen - und damit auch die darauf drehbar gelagerte Wendestange 17 - in Richtung x' und -x' bewegbar. Durch die Bewegbarkeit der Wendestange parallel zur Bewegungsrichtung des schlauchförmigen Materials 2 (in Richtung x' und -x') kann die Kantenlage unterschiedlich breiter Materialschläuche an die Querschneide- oder Vereinzelungsvorrichtung 6 angepasst werden. Der Spindelmotor 23 ist über eine geeignete Datenleitung 26 mit einer Steuereinrichtung 25 verbunden. In der Steuervorrichtung können die Breitenmaße der zu verarbeitenden Materialschläuche bereits gespeichert sein. Eine manuelle Eingabe dieser Breitenmaße ist jedoch auch möglich. Bei einem Auftragswechsel steuert die Steuervorrichtung 25 aufgrund der Breitenmaße des schlauchförmigen Materials den Spindelmotor 23 derart an, dass die Wendestange 17 in Richtung x' bewegt wird, bis die Kantenlage des schlauchförmigen Materials an die Querschneide- oder Vereinzelungsvorrichtung 6 angepasst ist.FIG. 2 shows a top view of the turning bar 17. The turning bar can be rotatably mounted on a holding frame 18 via a holder 24. The holding frame 18 is in the embodiment shown here in a plane which is parallel to the direction of movement of the tubular material 2. Below the holding frame 18 carriages 20, 27 are mounted, which engage in rails 19 (Figure 3). The holding frame 18 is movable by means of the carriages 20, 27 on the rails 19. The carriage 27 is extended in the direction z. At the lower end of the extended carriage 27, a spindle nut is incorporated, in which a spindle 21 engages. The spindle 21 is rotatable by means of the motor 23. By rotation of the spindle 21, which engages in the spindle nut of the extended slide 27, the holding frame - and thus also the rotatably mounted turning bar 17 - in the direction x 'and -x' movable. Due to the mobility of the turning bar parallel to the direction of movement of the tubular material 2 (in the direction x 'and -x'), the edge position of different widths of material hoses can be adapted to the cross-cutting or separating device 6. The spindle motor 23 is connected to a control device 25 via a suitable data line 26. In the control device, the width dimensions of the material hoses to be processed can already be stored. However, manual entry of these width dimensions is also possible. In a job change, the control device 25 controls the spindle motor 23 due to the width dimension of the tubular material such that the Turning bar 17 in the direction x 'is moved until the edge position of the tubular material is adapted to the cross-cutting or separating device 6.
Die Figur 4 zeigt die Seitenansicht einer Schlauchbildungsvorrichtung 13. Das bahnförmige Material 14 wird von einem Wickel 3 abgewickelt und einem nicht näher beschriebenen Schlauchbildungsbereich 28 zugeführt, in welchem 28 das bahnförmige Material 14 zu schlauchförmigem Material 2 verarbeitet wird. Anschließend gelangt das schlauchförmige Material über Führungsrollen 22 zur Wendestange 17. Alternativ kann auch im so genannten Offline-Modus bahnförmiges Material auf einem Wickel 4 aufgewickelt werden. Wie bereits erwähnt, wird der Materialschlauch 2 mithilfe der Wendestange 17 aus der ursprünglichen Transportrichtung x' in die Transportrichtung y gelenkt und einer Querschneidevorrichtung 6 zugeführt, die den Gewebeschlauch in einzelne Schlauchstücke 16 vereinzelt. Man kann anhand der Figur 4 erkennen, dass sich die Wendestange in einer Ebene oberhalb der Querschneidevorrichtung befindet. Die Vereinzelungs- oder Querschneidevorrichtung 6 kann auch von einem separaten Materialwickel 29 mit schlauchförmigem Material versorgt werden. Die Sackherstellungsvorrichtung kann in zwei Betriebsmodi betrieben werden. Im so genannten „Inline-Modus" wird die Querschneidevorrichtung 6 direkt von der Schlauchbildungsvorrichtung 13 - über die Wendestange 17 - mit bahnförmigem Material versorgt. Im so genannten „Offline-Modus" wird die Querschneidevorrichtung von einem separaten Wickel 29 mit schlauchförmigem Material versorgt. Das schlauchförmige Material kann zuvor von der Schlauchbildungsvorrichtung 13 hergestellt und zu einem Wickel 4 aufgewickelt worden sein. In diesem Fall würde zur Sackherstellung der Wickel 4 anschließend auf die Position des Wickels 29 gebracht.4 shows the side view of a hose forming device 13. The web-shaped material 14 is unwound from a roll 3 and fed to a hose forming region 28 not described in detail, in which 28 the web-shaped material 14 is processed into tubular material 2. Subsequently, the tubular material passes through guide rollers 22 to the turning bar 17. Alternatively, even in the so-called off-line mode web material can be wound on a winding 4. As already mentioned, the material hose 2 is guided by means of the turning bar 17 from the original transport direction x 'in the transport direction y and fed to a cross-cutting device 6, which separates the fabric tube into individual tube pieces 16. It can be seen with reference to FIG. 4 that the turning bar is located in a plane above the transverse cutting device. The separating or cross-cutting device 6 can also be supplied by a separate material winding 29 with tubular material. The bag making apparatus can be operated in two modes of operation. In the so-called "in-line mode", the cross-cutting device 6 is supplied with web-shaped material directly from the tube-forming device 13 via the turning bar 17. In the so-called "offline mode", the cross-cutting device is supplied with a tubular material by a separate winding 29. The tubular material may have previously been made by the tube forming device 13 and wound into a coil 4. In this case, the bag 4 would then be brought to the position of the roll 29 for bag production.
Unterhalb der Führungsrollen 22 befindet sich ein Durchgang 7, durch welchen 7 das Bedienpersonal hindurch schreiten kann. So sind für das Bedienpersonal der Sackherstellungsvorrichtung beide Maschinenseiten erreichbar, ohne die komplette Maschine umlaufen zu müssen. Dies ist besonders vorteilhaft, da mit der Hintereinanderstellung der Schlauchbildungseinrichtung 13 und der einzelnen Schlauchstück-Bearbeitungsstationen die Gesamtmaschinenlänge vergrößert wird. Die Position des Durchganges direkt neben der Vereinzelungsbzw. Querschneidevorrichtung 6 ist vorteilhaft, weil der Bediener so einfacher an die Querschneidevorrichtung 6 gelangen und beispielsweise Materialstauchungen beseitigen kann. Außerdem sind von dort beide Schlauchmaterialwickel 4 und 29 vom Bediener erreichbar. Dies ist sowohl bei auftretenden Fehlern wie auch bei einem Materialwickelwechsel vorteilhaft. Below the guide rollers 22 is a passage 7 through which 7 the operator can pass through. Thus, both sides of the machine can be reached by the operators of the bag making device without having to circulate the entire machine. This is particularly advantageous because with the succession of the tube forming device 13 and the individual piece piece machining stations the overall machine length is enlarged. The position of the passage next to the singling or. Cross-cutting device 6 is advantageous because the operator so easier to get to the cross-cutting device 6 and, for example, can eliminate material compression. In addition, from there both tubing wraps 4 and 29 can be reached by the operator. This is advantageous both in the case of errors occurring as well as in a Materialwickelwechsel.
