Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur kontinuierlichen Abfüllung einer vorgegebenen Menge eines Produktes, insbesondere eines Getränks oder Lebensmittels, in aus vorzugsweise von einer Rolle bereitgestelltem Packstoff, insbesondere Karton-Kunststoff-Verbundmaterial, hergestellte Packungen.The invention relates to a method and a device for the continuous filling of a predetermined amount of a product, in particular a beverage or food, in packs preferably made of a roll, in particular cardboard-plastic composite material.

Aus der Praxis sind unterschiedlichste Vorrichtungen zum Abfüllen von flüssigen, körnigen, pulverförmigen und/oder festen Produkten in Portionspackungen bekannt. Neben dem Abfüllen in Flaschen, Container oder dergleichen, also in bereits fertige Behältnisse, gibt es jedoch auch solche Anlagen, die die zu befüllenden Packungen zunächst aus einem Rohstoff oder Halbzeug herstellen. Solche Verbundpackungen bestehen meist aus innen und außen mit einer PE-versiegeltem Kartonträgermaterial und weisen ggf. darüber hinaus noch weitere Schichten als Sauerstoffsperrschicht, Lichtschutzschicht oder dergleichen auf. So enthalten beispielsweise Verbundpackungen für H-Milch eine zusätzliche Aluminiumfolie als Lichtschutzschicht.From practice a variety of devices for filling liquid, granular, powdery and / or solid products in sachets are known. In addition to bottling, containers or the like, so in already finished containers, but there are also those systems that produce the packs to be filled first from a raw material or semi-finished. Such composite packages usually consist of an inside and outside with a PE-sealed cardboard carrier material and, if appropriate, also have further layers as an oxygen barrier layer, light protection layer or the like. For example, composite packagings for UHT milk contain an additional aluminum foil as a light protection layer.

Aus den zu verwendenden Rohmaterialien werden in Verpackungsfabriken die einzelnen Schichten zu einem Verbundmaterial laminiert, dieses dann bedruckt und vereinzelt. Nach entsprechender Vorfaltung, Rillung, Prägung und Aufbringen der Längsnaht werden dann die Schlauchabschnitte, sogenannte "Packungsmäntel", flachgelegt in Umkartons, den eigentlichen Abfüllbetrieben zur Verfügung gestellt. Durch das Vereinzeln der Packungsmäntel ist bei dieser Art der Herstellung von Verbundpackungen eine Qualitätskontrolle während des Fertigungsprozesses möglich, so dass nur einwandfreie Packungsmäntel zu den Abfüllmaschinen gelangen.From the raw materials to be used in packaging factories, the individual layers are laminated to a composite material, which is then printed and separated. After appropriate pre-folding, grooving, embossing and applying the longitudinal seam then the tube sections, so-called "packing coats", laid flat in outer cartons, the actual bottling provided. By separating the packing shells, a quality control during the manufacturing process is possible in this type of production of composite packs, so that only flawless packing shells reach the filling machines.

Bei der alternativen Herstellung von Verbundpackungen von auf Rollenbahnen angeliefertem Verbundmaterial müssen festgestellte fehlerhafte Abschnitte der Rollen in einem Rollenschneider überarbeitet werden, indem die fehlerhaften Stellen entfernt, die Verpackungsmaterialbahn unter Bildung einer - zusätzlichen - Nahtstelle wieder "geflickt" werden. Solche Nahtstellen der Materialbahnen führen jedoch später zu Ausschussware, da aufgrund der stärkeren Materialanhäufung Undichtigkeiten sowie Probleme beim Druckbild auftreten können. Da hierbei jedoch nur die groben Fehler eliminiert werden können, muss auch weiterhin mit Materialfehlern oder Druckfehlern beim aufgerollten Verbundmaterial gerechnet werden.In the alternative production of composite packages of composite material delivered on roller conveyors, detected defective portions of the rolls must be reworked in a slitter by removing the defective areas, "patching" the packaging material web to form an additional seam. However, such seams of the webs later lead to rejects, since due to the increased accumulation of material leaks and problems in the printed image can occur. However, since only the gross errors can be eliminated, material defects or printing errors in the rolled-up composite material must continue to be expected.

Im eigentlichen Abfüllbetrieb werden die Rollen in einer Abfüllanlage geformt, abgeschnitten, befüllt und verschlossen. Das Endprodukt ist ein mit dem entsprechenden Produkt gefüllte Packung. Bei dem bekannten Verfahren bzw. mit den bekannten Vorrichtungen ist es nicht auszuschließen, dass Packungen mit fehlerhaften Innenoberflächen auf den Markt gebracht werden, weil nach dem Verschließen der Packung die Fehler durch die meist zerstörungsfreien Qualitätsprüfungen nicht erkannt werden. Auch ist nicht völlig auszuschließen, dass Packungen mit fehlerhaften Außenoberflächen oder fehlerhaftem Druck zum Endverbraucher gelangen, weil diese Packungen nach dem Verlassen der Füllmaschine meist sofort in Verkaufstrays palettiert werden.In the actual filling operation, the rolls are shaped, cut, filled and sealed in a filling plant. The final product is a package filled with the corresponding product. In the known method or with the known devices, it can not be ruled out that packages with faulty inner surfaces are brought to the market, because after the closure of the package, the errors are not recognized by the mostly non-destructive quality tests. It is also not completely ruled out that packs with faulty outer surfaces or faulty pressure reach the end user, because these packs are usually palletized immediately after leaving the filling machine in sales trays.

Der Erfindung liegt daher die Aufgabe zugrunde, das eingangs genannte und zuvor näher beschriebene Verfahren und die entsprechende Vorrichtung so auszugestalten und weiterzubilden, dass Defekte im Verbundmaterial und/oder Mängel der befüllten Packungen erkannt werden und die entsprechende Ausschussware aus dem Produktionsprozess entsorgt wird.The invention is therefore based on the object at the outset and described in more detail above method and the corresponding device and further educate, that defects in the composite material and / or defects of the filled packages are recognized and the corresponding rejects from the production process is disposed of.

Diese Aufgabe wird hinsichtlich des Verfahrens dadurch gelöst, dass eine Zentralsteuerung vor, während und nach der Abfüllung über eine Mehrzahl von Schnittstellen Informationsdaten über den Herstellungsprozess des Packstoffs, die Unversehrtheit des Packungsmantels und/oder der offenen Packung und den Abfüllprozess sammelt und den Produktionsprozess so beinflusst, dass defekte oder beschädigte Packungen nicht befüllt werden und dass nicht gefüllte oder gefüllte, jedoch undichte oder beschädigte Packungen aus dem laufenden Produktionsprozess ausgeschleust werden.With regard to the method, this object is achieved in that a central controller collects information data about the manufacturing process of the packaging material, the integrity of the packaging jacket and / or the open package and the filling process before, during and after filling via a plurality of interfaces and thus influences the production process in that defective or damaged packages are not filled and that unfilled or filled but leaky or damaged packages are removed from the current production process.

Hinsichtlich der Vorrichtung besteht die Lösung der Aufgabe darin, dass die Vorrichtung zur Durchführung des Verfahrens eine Zentralsteuerung, eine Mehrzahl von Detektoren zum Sammeln von Daten für die Zentralsteuerung und wenigstens eine Ausschleusvorrichtung zum Ausschleusen von nicht gefüllten oder gefüllten, jedoch undichten oder beschädigten Packungen aufweist.With regard to the device, the object of the invention is that the device for carrying out the method has a central control, a plurality of detectors for collecting data for the central control and at least one discharge device for the discharge of unfilled or filled, but leaky or damaged packages.

Für sich sind bereits einzelne Lösungen zur Qualitätskontrolle in Verbindung mit Füllmaschinen bekannt:For itself, individual solutions for quality control in connection with filling machines are already known:

So ist beispielsweise aus der DE 43 32 645 C2 eine Maschine zum Füllen von Getränken in auf Unversehrtheit geprüften Flaschen bekannt, die eine Vielzahl umlaufender Füllorgane aufweist, deren Flüssigkeitsventile einzeln von einer gemeinsamen Steuereinrichtung schaltbar sind. Die Maschine ist ferner mit einer Eingabeeinrichtung, in der die Flaschen einzeln separiert und synchron zum Maschinenumlauf laufend von einer zuführenden Transporteinrichtung auf die Maschine überführt werden, und mit einer Ausgabeeinrichtung, der unmittelbar oder unter Zwischenschaltung von Verschließ- und/oder Etikettiereinrichtungen eine Endkontrolleinrichtung nachgeschaltet ist, versehen. Die Endkontrolleinrichtung prüft die Flaschen auf Unterfüllung und entfernt sie ggf. aus dem Flaschenstrom. Außerdem weist diese Maschine eine Eingangskontrolleinrichtung auf, die im Bereich der Eingabeeinrichung die Flaschen auf Fehler überprüft und bei Feststellung eines Fehlers ein Signal zum Geschlossenhalten desjenigen Flüssigkeitsventils, das während des folgenden Umlaufs der als defekt erkannten Flasche zugeordnet ist, an die Steuereinrichtung abgibt. Die Eingangskontrolleinrichtung besteht in dem in der Zeichnung dargestellten Ausführungsbeispiel aus drei Videokameras, die über Bilderkennungseinrichtungen zur Fehlererkennung das Abschaltsignal erzeugen. Die Endkontrolleinrichtung, die die Flaschen daraufhin überprüft, ob sie unterfüllt sind, weist in dem dargestellten Ausführungsbeispiel eine Videokamera und eine Ausstosseinrichtung auf. Die Flaschen werden somit vor und nach dem Abfüllvorgang kontrolliert.For example, from the DE 43 32 645 C2 a machine for filling drinks in integrity tested bottles, having a plurality of circumferential filling members, the liquid valves are individually switchable by a common control device. The machine is further provided with an input device in which the bottles are individually separated and transferred synchronously to the machine cycle from a feeding conveyor to the machine, and with an output device, which is followed directly or with the interposition of sealing and / or labeling a final control device , Mistake. The final inspection device checks the bottles for underfilling and possibly removes them from the bottle stream. In addition, this machine has an input control device, which checks the bottles for errors in the area of the input device and, when a fault is detected, a signal to keep the liquid valve closed during the following Circulation of the bottle recognized as defective is assigned to the control device. The input control device consists in the embodiment shown in the drawing of three video cameras that generate the shutdown signal via image recognition devices for error detection. The final control device, which then checks the bottles for being underfilled, has a video camera and an ejection device in the exemplary embodiment shown. The bottles are thus checked before and after the filling process.

Des weiteren beschreibt die EP 0 378 052 A1 eine Verpackungsvorrichtung gemäss dem Oberbegriff des Anspruchs 6, die ein Beutelformmaschine aufweist und zum Herstellen von mit Schüttgut zu füllenden Beuteln aus einem Einschlagmaterialband dient, das über eine Eingangseinrichtung der Beutelformmaschine zugeführt wird. Die Eingangseinrichtung weist eine Kontrolleinrichtung zum Nachweis von Fehlern im Einschlagmaterial und Auslenkmittel auf, die bei einem Einschlagmaterialbandfehler den Anfang eines ankommenden Bandabschnittes in einen Ausscheidebehälter fallen lassen.Furthermore, the describes EP 0 378 052 A1 a packaging device according to the preamble of claim 6, which has a bag-forming machine and is used to produce bags to be filled with bulk material from a wrapping material strip, which is fed via an input device of the bag-forming machine. The input device has a control device for detecting defects in the wrapping material and deflection means, which fall in a Einschlagmaterialbandfehler the beginning of an incoming band section in a separation container.

Ferner sei noch auf die WO 98/ 05 558 hingewiesen, die ein Verfahren und eine Vorrichtung zur Erfassung von Konstruktionsfehlern in einer aus einem zweidimensionalen Zuschnitt hergestellten Verpackung beschreibt. Abschnitte der Verpackung weisen dabei Bereiche mit Konstrastfarben auf, welche optisch abgetastet werden. Die Abtastergebnisse werden einer elektronischen Kotrolleinheit zum Vergleich mit gespeicherten Parametern zugeführt. Wenn die Abtastergebnisse mit den gespeicherten Parametern nicht übereinstimmen, wird die betreffende Verpackung als fehlerhaft angesehen. Das in der Zeichnung dargestellt Ausführungsbeispiel betrifft die Kontrolle einer Verpackung zur Aufnahme von Joghurtbechern.Furthermore, be on the WO 98/05558 which describes a method and apparatus for detecting design errors in a package made from a two-dimensional blank. Sections of the packaging have areas with contrasting colors, which are optically scanned. The scan results are fed to an electronic knockout unit for comparison with stored parameters. If the sampling results do not match the stored parameters, the packaging in question is considered defective. The embodiment shown in the drawing relates to the control of a package for containing yogurt cups.

Die erfindungsgemäße Lösung basiert also auf der Erkenntnis, dass durch eine Zentralsteuerung Dateninformationen von unterschiedlichsten Oberflächenkontrollen und sonstigen Kontrollsystemen einheitlich erfasst und verarbeitet werden. Erfindungsgemäß ist erreicht worden, dass fehlerhafte Packungen dort aussortiert und entfernt werden, wo es imThe solution according to the invention is therefore based on the knowledge that data information from a wide variety of surface controls and other control systems is uniformly recorded and processed by a central control. According to the invention it has been achieved that defective packages are sorted out and removed there, where it is in

Bezug auf den gesamten Fertigungs- und Abfüllprozess kostenmäßig am günstigsten ist. Die Erfassung von Daten über bei der Packstoffherstellung auftretende Fehler in der Zentralsteuerung können - räumlich und zeitlich getrennt - Informationen über die Oberflächenbeschaffenheit und das Gewicht des Packstoffs, Nahtstelle, Druckfehler, etc. erst später beim eigentlichen Abfüllprozess ausgewertet und gemeinsam mit den erfassten Daten über den Abfüllprozess ausgewertet werden. Während des Abfüllprozesses werden Informationen über die Füllhöhe bzw. das Gewicht der gefüllten Packung, die Qualität der Siegelnaht bzw. Siegelnähte und den äußeren Stand der fertigen Packung sowie ggf. weitere produktionstechnisch bedingte Parameter gesammelt.In terms of cost, the lowest cost is related to the entire manufacturing and filling process. The acquisition of data on defects occurring during the production of packaging materials in the central control system - spatially and temporally separated - information about the surface condition and the weight of the packaging material, interface, printing errors, etc. evaluated later in the actual filling process and together with the collected data on the Bottling process to be evaluated. During the filling process, information about the filling level or the weight of the filled pack, the quality of the sealed seam or sealing seams and the outer state of the finished pack as well as possibly other production-related parameters are collected.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung lassen sich auf bestehende Abfüllanlagen mit geringen Umrüstarbeiten anwenden.The method according to the invention and the device according to the invention can be applied to existing filling plants with little retooling work.

Ein weiterer Vorteil der Erfindung ist es, dass über eine Prozesserfassungs-Software, die in der Zentralsteuerung erfassten Daten für die Erstellung einer exakten Kostenabrechnung für den Packstoffhersteller ausgewertet werden können. Mit einer solchen "automatischen Kombikontrollsystemanlage" lassen sich beim Abfüller Kosten sparen, indem dieser nur noch das Material für die einwandfreien Packungen bezahlen muss und die Kosten für den Ausschuss (und ggf. der gesamten erfindungsgemäßen Vorrichtung) dem Packstoffhersteller in Rechnung stellt. Aufgrund der beim Packstoffhersteller durch den Wegfall einer Qualitätskontrolle bedingten Einsparung sind die Gesamtkosten des Fertigungsprozesses durch die erfindungsgemäße Lösung geringer als bei herkömmlichen Prozessen. Für die Detektion der Fehler im Packstoff lassen sich optische, elektrische/elektronische oder mechanische Detektoren sowie Wiegevorrichtungen oder dergleichen einsetzen.A further advantage of the invention is that, via a process detection software, the data recorded in the central control can be evaluated for the production of an exact cost accounting for the packaging material manufacturer. With such an "automatic combination control system" costs can be saved at the bottler by this only has to pay the material for proper packaging and the cost of the Committee (and possibly the entire device according to the invention) the packaging material manufacturer invoices. Due to the packaging manufacturer's loss of quality control-related savings, the total cost of the manufacturing process by the inventive solution are lower than in conventional processes. For the detection of the defects in the packaging material can be optical, electrical / electronic or mechanical detectors and weighing devices or the like.

Im Rahmen der Erfindung ist es möglich, eine einzige, am Ende des Produktionsprozesses vorgesehene Ausschleusvorrichtung vorzusehen, wenn die gesamte Linie so ausgebildet werden kann, dass beschädigte oder fehlerbehaftete Packungen zwar die Fülleinheit durchlaufen, aber nicht mit Produkt gefüllt werden. Es ist jedoch auch möglich, vor den einzelnen Einheiten, also insbesondere vor der Auffalt- und Bodenformeinheit und/oder vor der eigentlichen Fülleinheit entsprechende Ausschleusvorrichtungen vorzusehen.Within the scope of the invention, it is possible to provide a single discharge device provided at the end of the production process, if the entire line can be formed such that damaged or faulty packages pass through the filling unit but are not filled with product. However, it is also possible to provide corresponding ejection devices in front of the individual units, that is to say in particular before the unfolding and bottom forming unit and / or before the actual filling unit.

Schließlich kann die am Ende des Produktionsprozesses vorgesehene Ausschleusvorrichtung auch mit Mitteln zum sortierten Ausschleusen, wie beispielsweise einer Doppelweiche, versehen sein, um neben der Produktlinie einwandfreier Produkte nicht nur Ausschussware auszusortieren, sondern auch minderwertige Ware separat auszuschleusen. Auf diese Weise ist es möglich, ordnungsgemäß gefüllte und einwandfrei dichte Packungen, die jedoch beispielsweise mit Druckfehlern behaftet sind, als minderwertige Ware auszusortieren.Finally, the discharge device provided at the end of the production process can also be provided with means for sorted discharge, such as, for example, a double diverter, in order to not only reject rejects in addition to the product line of perfect products, but also to reject inferior goods separately. In this way, it is possible properly sorted and properly sealed packs, however, for example, are prone to misprints to sort out as inferior goods.

Dabei weist die Vorrichtung zunächst und im Wesentlichen eine Rolle 1 zur Bevorratung des bahnförmigen Packstoffes und eine Abfüllanlage 2 auf, in der die aus dem bahnförmigen Packstoff ausgeformten Packungen mit einem Produkt 3 abgefüllt werden. Am Ende des Produktionsprozesses verlassen fertig gefüllte Packungen 4 die Vorrichtung.In Fig. 1 the device according to the invention is shown schematically. In this case, the device initially and essentially a roll 1 for storing the web-shaped packaging material and a filling plant 2, in which the packages formed from the web-shaped packaging material are filled with a product 3. At the end of the production process, ready-filled packages 4 leave the device.

Erfindungsgemäß weist nun die Vorrichtung darüber hinaus eine Zentralsteuerung 5, eine Oberflächenkontrollanlage 6 für Material- und/oder Druckfehler und eine Mehrzahl von Detektoren zum Sammeln von Daten für die Zentralsteuerung 5 auf. Darüber hinaus ist im dargestellten und insoweit bevorzugten Ausführungsbeispiel auch eine Wiegevorrichtung 7 zur Überprüfung des Füllgewichtes vorgesehen. Die zuvor genannten Detektoren zum Sammeln von Daten werden über mehrere Schnittstellen mit der Zentralsteuerung 5 verbunden. Es sind dies im Einzelnen eine Schnittstelle 9 zur externen Packstofffertigung, eine Schnittstelle 10, 11 zur Oberflächenkontrollanlage, eine Schnittstelle 12 zur Abfüllanlage, eine Schnittstelle 13 zur Wiegekontrolle, eine Schnittstelle 14 zur Ausschleusvorrichtung und eine Schnittstelle 15 zur Produktionserfassungs-Software.According to the invention, the device now also has a central control 5, a surface control system 6 for material and / or printing errors and a plurality of detectors for collecting data for the central control 5. In addition, in the illustrated preferred embodiment, a weighing device 7 is provided for checking the filling weight. The above-mentioned detectors for collecting data are connected to the central controller 5 via a plurality of interfaces. These are in detail an interface 9 for the external packaging material production, an interface 10, 11 for surface control system, an interface 12 to the bottling plant, an interface 13 for weighing control, an interface 14 to the discharge device and an interface 15 for production detection software.

In der Abfüllanlage 2 wird aus dem von der Rolle 1 kommenden Packstoff einzelne Zuschnitte hergestellt und diese in bekannter Weise geformt, mit einem Produkt 3 gefüllt und anschließend verschlossen. Vor dem Vereinzeln wird der bahnförmige Packstoff in der Oberflächenkontrollanlage 6 auf Fehler hin überprüft. Dabei sind im dargestellten Ausführungsbeispiel zur besseren Übersicht nur zwei Oberflächengeräte vorhanden; es ist klar, dass, wenn mehrere Packstoffrollen vorhanden sind, beispielsweise Aluminiumfolie und Papier für Schokoladenverpackungen, pro Rolle jeweils zwei Oberflächengeräte vorhanden sind.In the bottling plant 2, individual blanks are produced from the packaging material coming from the roll 1 and these are shaped in a known manner, filled with a product 3 and then sealed. Before separating the web-shaped packaging material in the surface control system 6 is checked for errors. In the illustrated embodiment, for better clarity, only two surface devices are present; it is clear that if there are several dunnage rolls, for example aluminum foil and paper for chocolate packaging, there will be two surface devices per roll.

Die Oberflächen des Packstoffs können beschichtet, kaschiert, bedruckt, gestanzt, perforiert, unbehandelt oder mit einem anderen Verfahren veredelt sein. Die Oberflächenkontrollanlage ist dabei jeweils auf die zu verarbeitende Packstoffart speziell angepasst. Die dort ermittelten Daten werden über die zugeordneten Schnittstellen 10, 11 an die Zentralsteuerung 5 übermittelt. Dabei werden Informationen über erkannte Oberflächenfehler oder Druckfehler detektiert. Dabei können die Fehler in unterschiedliche Fehlerklassen unterteilt werden.The surfaces of the packaging material can be coated, laminated, printed, stamped, perforated, untreated or refined by another method. The surface control system is specially adapted to the type of packaging material to be processed. The data determined there are transmitted via the assigned interfaces 10, 11 to the central controller 5. In this case, information about detected surface defects or printing errors is detected. The errors can be divided into different error classes.

Über die Schnittstelle 9 zur externen Packstofffertigung erhält die Zentralsteuerung 5 Informationen aus dem Fertigungsprozess der Packstoffrollenherstellung. Diese Dateninformationen können über Datenträger, zum Beispiel Disketten, online an die Zentralsteuerung 5 übermittelt werden. Zweckmäßiger Weise sind die Oberflächenkontrollsysteme beim Packstoffhersteller und dem Abfüllanlagenbetreiber aufeinander abgestimmt oder sogar vom gleichen Hersteller. In der Zentralsteuerung 5 werden die über die Schnittstelle 9 zur externen Packstofffertigung gesammelten Daten mit den Informationen aus der Oberflächenkontrollanlage abgeglichen.Via the interface 9 for the external production of packaging material, the central control 5 receives information from the production process of the packaging material roll production. This data information can be transmitted via data carriers, for example floppy disks, online to the central controller 5. The surface control systems are expediently coordinated with the packaging material manufacturer and the bottling plant operator or even by the same manufacturer. In the central controller 5, the data collected via the interface 9 for the external production of packaging material is compared with the information from the surface control system.

Weitere Dateninformationen erhält die Zentralsteuerung 5 von der Schnittstelle 12 zur Abfüllanlage, hierbei umfassen die Dateninformationen beispielsweise fehlerhafte Abfüllprodukte, Abfüllschwierigkeiten, Maschinengeschwindigkeit und andere Prozessinformationen. Eine weitere Dateninformation erhält die Zentralsteuerung 5 von der Schnittstelle 13 zur Wiegekontrolle. Dort werden die abgefüllten Produkte und Packungen gewogen und mit einem Sollwert verglichen. Wird der Sollwert mit den zugelassenen Abweichungen nicht erreicht, bekommt die Zentralsteuerung 5 wiederum eine entsprechende Dateninformation. Weitere Detektoren können hinter der Abfüllanlage 12 angeordnete Metallsuchkontrollsysteme oder sonstige Kontrollsysteme sein, die ebenfalls in die Zentralsteuerung 5 eingebunden werden können. In der Zentralsteuerung 5 werden alle Dateninformationen verarbeitet und mit vorgegebenen Sollwerten und Fehlerklassen abgeglichen werden. Alle Daten berücksichtigen dabei die Maschinengeschwindigkeit der gesamten Vorrichtung. Von der Zentralsteuerung 5 werden dann die aus den unterschiedlichen Detektoren erkannten Fehler in mindestens die Kategorien a) einwandfreie Packungen 4, b) minderwertige Packungen 4' und c) Ausschuss 4" unterteilt.The central controller 5 receives further data information from the interface 12 to the bottling plant, in which case the data information includes, for example, defective bottling products, bottling difficulties, machine speed and other process information. The central controller 5 receives further data information from the interface 13 for weighing control. There, the bottled products and packs are weighed and compared with a setpoint. If the nominal value with the permitted deviations is not reached, the central controller 5 again receives corresponding data information. Further detectors may be arranged behind the filling 12 metal search control systems or other control systems, which can also be integrated into the central control 5. In the central controller 5, all data information is processed and compared with predetermined setpoints and error classes. All data takes into account the machine speed of the entire device. The central controller 5 then divides the errors detected from the different detectors into at least the categories a) perfect packs 4, b) inferior packs 4 'and c) broke 4 ".

Dementsprechend wird die Ausschleusvorrichtung 8, welche im dargestellten und insoweit bevorzugten Ausführungsbeispiel als "Doppelweiche" ausgeführt ist, von der Zentralsteuerung 5 angesteuert.Accordingly, the discharge device 8, which is embodied in the illustrated preferred embodiment as a "double switch", is controlled by the central controller 5.

Wird durch die Oberflächenkontrollanlage 6 ein Fehler der Fehlerklasse "Ausschuss" festgestellt oder ist eine entsprechende Information aus der Packstoffherstellung 9 vorhanden, gibt die Zentralsteuerung 5 zusätzlich zu dem Signal an die Ausschleusvorrichtung 8 ein weiteres Signal an die Steuerung der Abfüllanlage 2, um durch eine nicht dargestellte Dosierstation die Zuführung des abzufüllenden Produktes zu stoppen. Die fehlerhafte Verpackung wird daher nicht abgefüllt, leer verschlossen und weiter transportiert und erst in der Ausschleusvorrichtung 8 ausgeschleust. Die Anzahl der ausgeschleusten Packungen 4, 4', 4'' mit den zugehörigen Fehlerklassen werden von der Zentralsteuerung 5 über die Schnittstelle 15 zur Produktionserfassungs-Software, dem ggf. vorhandenen Produktionsdatenerfassungssystem oder einem anderen Abrechnungssystem mitgeteilt. Aufgrund dieser Dateninformationen kann nun eine exakte Kostenabrechnung für den Packstoffhersteller erstellt werden. Mit der erfindungsgemäßen Vorrichtung muss der Packstoffhersteller also seine Produktionsfehler nicht mehr aufwendig und kostenintensiv entfernen. Die Fehlerdaten werden an den Abfüller weitergegeben und werden bei der eigentlichen Abfüllung aussortiert. Auf diese Weise kann der Abfüllbetrieb dem Packstoffhersteller einen erheblichen Aufwand sparen. Die Kosten der abfüllseitigen Entfernung von Produktionsfehlern sind in der Regel wesentlich geringer als eine entsprechende Qualitätskontrolle beim Packstoffhersteller.If the surface control system 6 detects an error of the defect class "rejects" or if corresponding information from the production of packaging material 9 is present, the central control 5 sends, in addition to the signal to the discharge device 8, a further signal to the control of the filling installation 2 in order to prevent it from coming off Dosing station shown to stop the supply of the product to be filled. The faulty packaging is therefore not filled, sealed and transported empty and discharged in the discharge device 8. The number of discharged packages 4, 4 ', 4''with the associated error classes are communicated by the central controller 5 via the interface 15 to the production registration software, the possibly existing production data acquisition system or another accounting system. Based on this data information, an exact cost accounting for the packaging material manufacturer can now be created. With the device according to the invention, the packaging material manufacturer therefore no longer has to remove his production errors in a costly and expensive manner. The error data are passed on to the bottler and are sorted out during the actual filling. In this way, the filling operation can save the packaging material manufacturer a considerable effort. The cost of filling-side removal of production errors are usually much lower than a corresponding quality control in the Packaging material manufacturer.

Fig. 2 zeigt ein weiteres Ausführungsbeispiel der erfindungsgemäßen Vorrichtung. Dabei sind eine Vereinzelungseinheit 16 und eine Aufformeinheit 17 vor der eigentlichen Abfüllanlage 2 angeordnet. Auch diese können wiederum mit weiteren Detektoren versehen sein, so dass in zusätzlich angeordneten Ausschleusvorrichtungen 8', 8" fehlerhafte Zuschnitte bzw. fehlerbehaftete Leerpackungen ausgeschleust werden. Die entsprechend detektierten Daten werden über die Zentralsteuerung 5 an zugehörige Schnittstellen 14' und 14" an die Anschleusvorrichtungen 8' und 8'' weitergegeben. Auf diese Weise ist es möglich, jede, die Abfüllanlage 2 erreichende Packung mit dem abzufüllenden Produkt 3 zu befüllen. Fig. 2 shows a further embodiment of the device according to the invention. In this case, a separation unit 16 and an impression unit 17 are arranged in front of the actual filling installation 2. These can in turn also be provided with further detectors so that faulty blanks or faulty empty packs are discharged in additionally arranged discharge devices 8 ', 8 ".The corresponding detected data are transmitted via the central control 5 to the associated interfaces 14' and 14" to the attachment devices 8 'and 8''passed. In this way it is possible to fill each, the filling line 2 reaching pack with the product to be filled 3.
