Description

System und Verfahren zum Herstellen von Säcken oder Beuteln  System and method for making sacks or bags
Die Erfindung betrifft ein System zum Herstellen von Säcken oder Beuteln, welches mindestens zwei Maschinen enthält, welchen Steuerkomponenten zugeordnet sind und welche durch zumindest eine Transport- und eine Lagervorrichtung mit einander verbunden sind. The invention relates to a system for producing sacks or bags, which contains at least two machines, which are associated with control components and which are connected by at least one transport and a bearing device with each other.
Weiterhin betrifft die Erfindung ein Verfahren zum Herstellen von Säcken oder Beuteln, bei welchem mindestens zwei Maschinen betrieben werden, und bei welchem zumindest eine Transport- und eine Lagervorrichtung Beutel bzw. Sackhalbzeuge zwischen den zumindest zwei Maschinen transportiert und/oder zwischen den zumindest zwei Maschinen lagert. Furthermore, the invention relates to a method for producing sacks or bags, in which at least two machines are operated, and in which at least one transport and a storage device bag or semi-finished sacks transported between the at least two machines and / or stored between the at least two machines ,
Zur Herstellung von Säcken oder Beuteln sind mehrere Schritte erforderlich, die in zumindest zwei Maschinen erfolgen, die das eingangs genannte System bilden. Zunächst werden in der Regel Schlauchstücke aus einer oder mehreren flachen Materialbahnen, meist Papier- und/oder Kunststoffbahnen hergestellt, indem diese Bahnen zunächst zu einem Schlauch zusammengelegt werden, wobei die sich überlappenden Randbereiche miteinander mit Klebstoff verklebt werden. Anschließend wird der Schlauch in Schlauchstücke vereinzelt. Diese Maschine zum Bilden der Schlauchstücke wird als Schlauchmaschine bezeichnet. Eine solche Schlauchmaschine ist in der Druckschrift DE 197 04 332 A1 offenbart. For the production of sacks or bags several steps are required, which take place in at least two machines that form the system mentioned above. First, pieces of tubing are usually produced from one or more flat sheets of material, usually paper and / or plastic sheets, by first folding these sheets into a tube, wherein the overlapping edge portions are glued together with adhesive. Then the hose is separated into pieces of hose. This machine for forming the hose pieces is called a tube machine. Such a tube machine is disclosed in the document DE 197 04 332 A1.
In einer so genannten Bodenlegemaschine werden an einem oder an beiden offenen Enden dieser Schlauchstücke Böden geformt, in dem die Enden unter Ausbildung von Bodenrechtecken und Dreieckstaschen aufgezogen werden. In a so-called floor laying machine, soils are formed at one or both open ends of these pieces of tubing, in which the ends are raised to form bottom rectangles and triangular pockets.
BESTÄTIGUNGSKOPIE Teile der Bodenrechtecke werden anschließend, zum Teil nach Einbringung eines Ventilzettels, zurückgefaltet und mit Klebstoff verklebt. Auf diese Weise entsteht ein befüllbarer Sack. An geeigneten Stellen in dieser Maschine können zusätzlich noch Innenriegel und/oder Bodendeckblätter aufgeklebt werden. Schließlich werden die Säcke zu Sackstapeln angeordnet. Wichtige Funktionen von Bodenlegemaschinen sind den Druckschriften DE 195 40 148 A1 , DE 195 40 150 A1 , DE 196 21 586 A1 , DE 103 09 893 A1 , D1 103 27 646 A1 , EP 1 892 086 A1 und DE 103 30 750 A1 zu entnehmen. In einer weiteren Maschine, der Palettiermaschine, können die Sackstapel auf Paletten angeordnet werden, so dass eine große Anzahl an Säcken auf einfache Weise abtransportiert werden können. Die Druckschriften DE 100 22 272, DE 103 09 131 und DE 10 2005 049 964 A1 zeigen solche Palettiermaschinen. CONFIRMATION COPY Parts of the Bodenrechtecke are then folded back, in part after the introduction of a Ventilzettels, and glued with adhesive. This creates a bag that can be filled. In addition, inside bars and / or bottom cover sheets can be glued on to suitable places in this machine. Finally, the sacks are arranged into sack stacks. Important functions of floor laying machines can be found in the publications DE 195 40 148 A1, DE 195 40 150 A1, DE 196 21 586 A1, DE 103 09 893 A1, D1 103 27 646 A1, EP 1 892 086 A1 and DE 103 30 750 A1 , In another machine, the palletizing machine, the sack stacks can be arranged on pallets, so that a large number of sacks can be transported away in a simple manner. The documents DE 100 22 272, DE 103 09 131 and DE 10 2005 049 964 A1 show such palletizing machines.
Weitere Maschinen können im Produktionsprozess integriert sein. Other machines can be integrated in the production process.
Im Rahmen dieser Patentanmeldung sind unter Maschinen alle Maschinen zu verstehen, die Material, also beispielsweise Materialbahnen, Schlauchstücke oder fertige Säcke ver- oder bearbeiten, behandeln, anordnen oder andere Veränderungen an ihnen vornehmen. Den Maschinen sind Steuerkomponenten zugeordnet, welche die für den Betrieb der Maschine notwendigen Funktionen und Aggregate steuern. Solche Steuerkomponenten können Hardware- Elemente, wie etwa eine SPS (speicherprogrammierbare Steuerungseinheit) oder ein IPC (Industrie-PC) sein. Auch Software-Code kann Bestandteil der Steuerkomponenten sein. Die Steuerung kann dabei auf der Basis der vom Bedienpersonal vorgegebenen Anforderungen erfolgen. So kann das Bedienpersonal beispielsweise die Fertigungsgeschwindigkeit vorgeben. Zwischen den einzelnen Maschinen ist jeweils zumindest eine Transport- oder Lagervorrichtung vorzusehen, die die Maschinen miteinander verbindet. Das bedeutet, dass die Werkstücke, also die Schlauchstücke oder Säcke, mit diesen Transport- und/oder Lagervorrichtungen zwischen den Maschinen transportiert werden können, wobei diese Vorrichtungen eine gewisse Menge an Werkstücken (Speichervolumen) aufnehmen können. Jedes Werkstück, das durch eine Transport- und/oder Lagervorrichtung von einer Maschine übernommen wird, wird also nicht sofort von der im Produktionsfluss folgenden Maschine weiterverarbeitet. Vielmehr verweilt das Werkstück in dieser Vorrichtung. Dadurch wird das ausreichende Abtrocknen der Klebstoffe ermöglicht. Außerdem wird ein Puffer für den Fall geschaffen, dass eine der Maschinen nicht mit ausreichender Leistungsfähigkeit arbeiten kann. Die Transport- und/oder Lagervorrichtungen stellen somit einen Speicher dar. In den Transport- und Lagervorrichtungen werden in der Regel keine Veränderungen an den Werkstücken vorgenommen. Es kommt lediglich zu einer Ortsveränderung. Die Werkstücke können einzeln, vorzugsweise aber in Stapeln, transportiert oder gelagert werden. Eine solche Transport- und/oder Lagereinrichtung ist in der WO 2005/018923 A1 offenbart. Wenn nun alle der genannten Maschinen und Transport- und Lagervorrichtungen mit einer gleichen, möglichst hohen Fertigungsgeschwindigkeit betrieben werden, so ist der maximale Durchsatz des Systems erreichbar. Die maximale Fertigungsgeschwindigkeit wird dabei von der langsamsten Maschine bestimmt. Oft ist dies die Bodenlegemaschine. In the context of this patent application, machines are to be understood as meaning all machines which process or process, treat, arrange or make other changes to material, for example material webs, pieces of tubing or finished sacks. The machines are assigned control components which control the functions and units necessary for the operation of the machine. Such control components may be hardware elements such as a PLC (Programmable Logic Control Unit) or an IPC (Industrial PC). Software code can also be part of the control components. The control can be done on the basis of the requirements imposed by the operator. For example, the operating personnel can specify the production speed. In each case at least one transport or storage device is to be provided between the individual machines, which connects the machines to one another. This means that the workpieces, so the pieces of hose or bags, can be transported between the machines with these transport and / or storage devices, these devices a certain amount of Workpieces (storage volume) can record. Each workpiece, which is taken over by a transport and / or storage device of a machine, so it is not processed immediately by the following in the production flow machine. Rather, the workpiece dwells in this device. This allows sufficient drying of the adhesives. In addition, a buffer is created in case one of the machines can not work with sufficient capacity. The transport and / or storage devices thus represent a memory. In the transport and storage devices usually no changes are made to the workpieces. It only comes to a change of location. The workpieces can be transported or stored individually, but preferably in stacks. Such a transport and / or storage device is disclosed in WO 2005/018923 A1. Now, if all of the above machines and transport and storage devices are operated with the same, highest possible production speed, the maximum throughput of the system can be achieved. The maximum production speed is determined by the slowest machine. Often this is the floor laying machine.
Die tatsächlichen Fertigungsgeschwindigkeiten der Maschinen, insbesondere der Schlauchmaschine und der Bodenlegemaschine, werden durch verschiedene Einflüsse herabgesetzt. So muss beispielsweise die Produktion in der Schlauchmaschine unterbrochen werden, wenn eine Rolle, auf die die Materialbahnen gewöhnlich gewickelt sind, gewechselt werden muss. Oft bleibt dann aber für die Bodenlegemaschine der Nachschub weg, so dass sich diese im Leerlauf befindet oder ebenfalls angehalten muss. Im ersten Fall kommt es zu einem unnötigen Ressourcenverbrauch, im zweiten Fall muss die Maschine wieder auf die Fertigungsgeschwindigkeit hochgefahren werden, was neben einem Zeitverlust in der Regel auch einen so genannten Anfahrausschuss (Produktion nicht brauchbarer Säcke oder Beutel) zur Folge hat. Der in der Praxis auftretende, tatsächliche Durchsatz bleibt also oft hinter dem maximal möglichen Durchsatz zurück. Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung und ein Verfahren vorzuschlagen, mit denen der tatsächliche Durchsatz zu erhöhen ist. The actual production speeds of the machines, in particular the hose machine and the floor laying machine, are reduced by various influences. For example, the production in the tube machine must be interrupted if a roll on which the material webs are usually wound must be changed. Often, however, the replenishment is left for the floor laying machine, so that it is idle or has also stopped. In the first case, there is an unnecessary consumption of resources, in the second case, the machine must be restarted to the production speed, which in addition to a loss of time usually also has a so-called start-up committee (production of unusable bags or bags) result. The actual throughput that occurs in practice often lags behind the maximum possible throughput. The object of the present invention is therefore to propose an apparatus and a method with which the actual throughput is to be increased.
Die Aufgabe wird gelöst durch ein System nach dem Oberbegriff des Anspruchs 1 , dem die Merkmale des Kennzeichens dieses Anspruchs hinzugefügt wurden. The object is achieved by a system according to the preamble of claim 1, to which the features of the characterizing part of this claim have been added.
Demnach ist eine Steuereinheit vorgesehen, welche derart eingerichtet ist, dass ihr die Fertigungsgeschwindigkeiten zumindest zweier Maschinen übermittelbar sind und welche derart eingerichtet ist, dass sie die Fertigungsgeschwindigkeiten zumindest zweier Maschinen aufgrund von Betriebsparametern des Systems vorschlägt und/oder einstellt. Von besonderem Vorteil ist dabei, wenn die absoluten Fertigungsgeschwindigkeiten vorschlagbar und/oder einstellbar sind. Die Aufgabe wird zudem durch den Anspruch 3 gelöst, nach dem einer Steuereinheit die Fertigungsgeschwindigkeit der zumindest zwei Maschinen und zumindest ein anderer Betriebsparameter der Maschinen, Transport- und/oder Lagervorrichtungen gemeldet wird und die Steuereinheit die Fertigungsgeschwindigkeit zumindest einer der zumindest zwei Maschinen aufgrund der gemeldeten Werte vorschlägt und/oder einstellt. Das Wort„Werte" steht hierbei abkürzend für die Fertigungsgeschwindigkeit und den zumindest einen anderen Betriebsparameter. Accordingly, a control unit is provided, which is set up so that the production speeds of at least two machines can be transmitted to it and which is set up in such a way that it proposes and / or sets the production speeds of at least two machines on the basis of operating parameters of the system. Of particular advantage is when the absolute production speeds are proposed and / or adjustable. The object is also achieved by claim 3, according to which a control unit, the production speed of at least two machines and at least one other operating parameters of the machinery, transport and / or storage devices is reported and the control unit, the production speed of at least one of the at least two machines due to the reported Suggests and / or sets values. The word "values" stands for the production speed and the at least one other operating parameter.
Der Erfindung liegt der Gedanke zugrunde, dass eine Maschine, wenn sie produktionsbereit ist, auch produzieren können soll. Das bedeutet, dass von der vorgeordneten Transport- und/oder Lagervorrichtung Werkstücke übernehmbar sein müssen und/oder dass die bearbeiteten Werkstücke auch durch eine folgende Transport- und/oder Lagervorrichtung abgenommen werden müssen. Das Speichervolumen der Transport- und/oder Lagervorrichtung darf also zu keinem Zeitpunkt vollständig ausgeschöpft werden, das heißt, die Transport- und/oder Lagervorrichtung darf nie gänzlich geleert oder gefüllt sein. In diesem Fall können ein Leerlauf oder ein Stillstand und der damit einhergehende Anfahrausschuss vermieden werden. Um dieses zu erreichen, erfasst die Steuereinheit neben den Fertigungsgeschwindigkeiten auch zumindest einen weiteren Betriebsparameter, um hierauf entsprechend reagieren zu können. Die Reaktion äußert sich im Einstellen von passenden Fertigungsgeschwindigkeiten, so dass in allen Transport- und Lagervorrichtungen stets sowohl Werkstücke als auch freie Plätze zur Verfügung stehen. The invention is based on the idea that a machine, if it is ready for production, should also be able to produce. This means that from the upstream transport and / or storage device workpieces must be accepted and / or that the machined workpieces must be removed by a subsequent transport and / or storage device. The storage volume of the transport and / or storage device may therefore at no time be completely exhausted, that is, the transport and / or storage device must never be completely emptied or filled. In this case, idling or stoppage and the associated start-up committee can be avoided. In order to achieve this, the control unit not only records the production speeds but also at least one further operating parameter in order to be able to react accordingly. The reaction manifests itself in the setting of suitable production speeds, so that both workpieces and free places are always available in all transport and storage devices.
In einer vorteilhaften Ausführungsform ist vorgesehen, dass die Steuereinheit die Fertigungsgeschwindigkeit zumindest einer Maschine aufgrund der gemeldeten Werte einer vorgelagerten und/oder der nachgelagerten Maschine vorschlägt und/oder einstellt. Steht beispielsweise bei der Schlauchmaschine ein Rollenwechsel an, so kann im Vorfeld bereits die Fertigungsgeschwindigkeit der Bodenlegemaschine entsprechend verringert werden, so dass sich der Speicher entsprechend füllt. Alternativ kann ein höherer Füllungsgrad des Speichers erreicht werden, indem die Schlauchmaschine im Vorfeld des Rollenwechsels mit einer höheren Fertigungsgeschwindigkeit betrieben wird. In an advantageous embodiment it is provided that the control unit proposes and / or sets the production speed of at least one machine on the basis of the reported values of an upstream and / or downstream machine. If, for example, a roll change occurs in the hose machine, the production speed of the floor laying machine can already be correspondingly reduced in advance, so that the store fills up accordingly. Alternatively, a higher degree of filling of the storage can be achieved by the tubular machine is operated at a higher production speed in the run-up to the roll change.
Vorteilhaft ist dabei, wenn die Steuereinheit die Fertigungsgeschwindigkeit zumindest einer Maschine derart regelt, dass der Füllstand zumindest einer Transport- und/oder Lagervorrichtung einem Sollwert zustrebt. Bevorzugt wird dabei, dass eine Maschine derart geregelt wird, dass der Füllstand der nachfolgenden Transport- und/oder Lagervorrichtung einem Sollwert zustrebt. Weiterhin ist es vorteilhaft, wenn dieser Sollwert von der Steuereinheit im Verlauf der Produktion angepasst wird. So kann bei einer bevorstehenden Verringerung der Fertigungsgeschwindigkeit einer Maschine der Sollwert für die Speicherbelegung der vorgelagerten Transport- und/oder Lagervorrichtung verringert und/oder der Sollwert für die Speicherbelegung der nachgelagerten Transport- und/oder Lagervorrichtung erhöht werden. It is advantageous if the control unit controls the production speed of at least one machine such that the level of at least one transport and / or storage device strives for a desired value. It is preferred that a machine is controlled such that the level of the subsequent transport and / or storage device strives for a desired value. Furthermore, it is advantageous if this desired value is adapted by the control unit in the course of production. Thus, in the case of an imminent reduction in the production speed of a machine, the setpoint value for the memory occupancy of the upstream transport and / or storage device can be reduced and / or the setpoint value for the memory occupancy of the downstream transport and / or storage device can be increased.
Der Sollwert kann dabei verschiedene Zahlenwerte annehmen. Dieser kann sich zwischen einer oberen Grenze und einer unteren Grenze bewegen, wobei diese Grenzen innerhalb des Speichervolumens liegen. Diese Zahlenwerte können Relativwerte zum maximalen Speichervolumen sein. So können die Sollwerte im Bereich zwischen 10 % und 90 % des maximalen Speichervolumens der betreffenden Transport- und/oder Lagervorrichtung liegen. Auch feste Werte, beispielsweise gemessen in Anzahl der Säcke oder Anzahl der Sackstapel, können solche Grenzen bilden. In weiterer Ausgestaltung der Erfindung ist vorgesehen, diese Grenzen zu über- oder zu unterschreiten, wenn unvorhergesehene Veränderungen der Betriebsparameter auftreten, etwa Störungen, die zum Stillstand einer Maschine führen. Die Grenzen können festgelegt sein oder vom Bedienpersonal vorgebbar oder während des Betriebes einstellbar sein. Es können etwa engere Grenzen (beispielsweise zwischen 20 % und 80 %) und entsprechend größere Speicherreserven können vorteilhaft sein, wenn eine höhere Störungsanfälligkeit zu befürchten ist. Ebenso können weitergehende Grenzen vorteilhaft sein, beispielsweise wenn der Produktionsprozess sehr stabil ist. The setpoint can assume different numerical values. This can move between an upper limit and a lower limit, these limits being within the storage volume. These numerical values can be relative values to the maximum storage volume. Thus, the setpoints can be in the range between 10% and 90% of the maximum storage volume of the relevant transport and / or storage device. Even fixed values, for example measured in number of sacks or number of sack stacks, can form such limits. In a further embodiment of the invention, it is provided to exceed or fall short of these limits if unforeseen changes in the operating parameters occur, for example faults which lead to the stoppage of a machine. The limits may be fixed or predefinable by the operating personnel or adjustable during operation. There may be narrower limits (for example, between 20% and 80%) and correspondingly larger memory reserves may be advantageous if a higher susceptibility to interference is to be feared. Likewise, more extensive limits may be advantageous, for example if the production process is very stable.
Die Steuereinheit erfasst neben den Fertigungsgeschwindigkeiten auch zumindest einen weiteren Betriebsparameter, der die optimale Fertigungsgeschwindigkeit beeinflussen kann. Diese Betriebsparameter lassen sich in zwei Teile gliedern. Zum einen sind dies Parameter, die einmalig, beispielsweise vor Produktionsbeginn eines Auftrages erfasst werden. Hierzu gehören das Format der Säcke, der zu verwendende Klebstoff, der Umfang des Auftrages (Auftragsmenge), der Durchmesser der Rollenhülsen, vorgegebene Reinigungs- oder Wartungsintervalle, die für eine ordnungsgemäße Verklebung erforderliche Trockenzeit, die maximal möglichen Beschleunigungen der Maschinen in Abhängigkeit vom Produkt, die maximale Geschwindigkeit der Maschine in Abhängigkeit vom Produkt oder das maximale Speichervolumen der Transport- und/oder Lagervorrichtungen. Das Speichervolumen wird dabei als Anzahl der speicherbaren Schlauchstücke, Säcke oder Beutel angegeben. Ein weiterer Betriebsparameter kann eine optimale Maschinengeschwindigkeit sein. Dieser Parameter kann dabei auf Erfahrungswerten beruhen. Einige der aufgeführten Parameter können durch die Steuereinheit berechenbar sein. So kann beispielsweise das maximale Speichervolumen aus dem Format der Säcke berechnet werden. Diese Werte können für einen Folgeauftrag auch bereits während eines laufenden Auftrags eingegeben oder ermittelt werden, so dass die Steuereinheit die Fertigungsgeschwindigkeiten des laufenden Auftrags bereits unter Berücksichtigung der Betriebsparameter des Folgeauftrages einstellen und/oder vorschlagen kann. So finden beispielsweise die gegebenenfalls notwendigen Umrüstzeiten Niederschlag in den Fertigungsgeschwindigkeiten. In addition to the production speeds, the control unit also detects at least one further operating parameter which can influence the optimum production speed. These operating parameters can be divided into two parts. On the one hand, these are parameters that are recorded once, for example before the start of production of an order. These include the format of the bags, the adhesive to be used, the size of the order (order quantity), the diameter of the roller sleeves, specified cleaning or maintenance intervals, the drying time required for proper bonding, the maximum possible machine acceleration depending on the product, the maximum speed of the machine depending on the product or the maximum storage volume of the transport and / or storage devices. The storage volume is specified as the number of storable pieces of tubing, bags or bags. Another operating parameter may be an optimal engine speed. This parameter can be based on empirical values. Some of the listed parameters may be calculable by the controller. For example, the maximum storage volume can be calculated from the size of the bags. These values can also be entered or determined for a follow-up order during a running job, so that the control unit can already set and / or suggest the production speeds of the current order, taking into account the operating parameters of the follow-up order. For example, if necessary, changeover times will result in precipitation in the production speeds.
Aber auch Betriebsparameter aus der laufenden Produktion können von der Steuereinheit erfasst oder berechnet werden. Dazu gehören beispielsweise Fehlermeldungen von oder Störungen an Maschinenkomponenten, die aktuelle Belegung der Transport- und/oder Lagervorrichtungen, die Restlaufzeit des Auftrags oder die aktuellen Durchmesser der Materialbahnrollen. Die Erfassung oder die Berechnung des Rollendurchmessers kann dazu ausgenutzt werden, um den Zeitpunkt des nächsten Rollenwechsels und damit des nächsten Stillstands der Maschine zu bestimmen. Auch andere Werte können hierzu herangezogen werden. So kann beispielsweise rechtzeitig vor diesem Stillstand die nachfolgende Transport- und/oder Lagervorrichtung gefüllt werden (gegebenenfalls kann der genannte Sollwert erhöht werden), in dem die vorgelagerte Maschine mit einer höheren Fertigungsgeschwindigkeit betrieben wird, und/oder die Fertigungsgeschwindigkeit der nachfolgenden Maschine verringert werden, so dass beim Rollenwechsel die nachfolgende Maschine weiter produzieren kann. Ein notwendiger Palettenwechsel in der Palettiermaschine ist ein weiterer Betriebsparameter. Auch kann in einem solchen Fall die vorangehende Transport- und/oder Lagervorrichtung geleert und/oder die Fertigungsgeschwindigkeit der vorhergehenden Maschine verringert werden. But also operating parameters from the current production can be recorded or calculated by the control unit. These include, for example, error messages from or faults in machine components, the current occupancy of the transport and / or storage devices, the remaining time of the order or the current diameter of the web rolls. The acquisition or calculation of the roll diameter can be used to determine the time of the next roll change and thus the next standstill of the machine. Other values can also be used for this purpose. Thus, for example, the following transport and / or storage device can be filled in good time prior to this standstill (if necessary, the specified value can be increased), in which the upstream machine is operated at a higher production speed, and / or the production speed of the subsequent machine is reduced, so that when reel change the subsequent machine can continue to produce. A necessary pallet change in the palletizing machine is another operating parameter. Also in such a case the preceding transport and / or storage device can be emptied and / or the production speed of the preceding machine can be reduced.
Der Maschinenbediener kann darüber hinaus Stillstände bestimmter Zeitdauern anfordern. In der laufenden Produktion kann es vorkommen, dass ein Bauteil einen Defekt erleidet, der jedoch für eine gewisse Zeit hinnehmbar ist, ohne dass die Funktionsfähigkeit der Maschine beeinträchtigt ist. Die Anforderung eines Stillstandes zur Beseitigung dieses Defektes kann von der Steuereinheit berücksichtigt werden. Diese schlägt dann einen Zeitpunkt für den Stillstand vor oder legt diesen fest. Nicht voraussehbare, aber dennoch notwendige Wartungsarbeiten können ebenfalls Anlass für die Anforderung eines Stillstandes sein. The machine operator can also request shutdowns of certain periods. In current production, it can happen that a component suffers a defect which, however, is acceptable for a certain period of time without impairing the functioning of the machine. The requirement of a standstill for the elimination of this defect can be taken into account by the control unit. This then suggests or sets a time for standstill. Unpredictable, but necessary Maintenance work can also be the reason for requesting a shutdown.
Die genannten Betriebsparameter der laufenden Produktion lassen sich nochmals in voraussehbare oder kalkulierbare (anstehende Wechsel, anstehende Wartungsarbeiten, Anforderungen von Stillständen) und in plötzlich auftretende oder verändernde (Defekt, welcher die Funktionsfähigkeit der Maschine beeinträchtigt) Betriebsparameter unterscheiden. Vorteilhaft ist darüber hinaus, wenn die Steuereinrichtung zumindest einen Teil der Produktionsparameter und/oder daraus abgeleitete Informationen auf einer Anzeigeeinrichtung sichtbar macht, auf der die anzeigten Parameter der jeweiligen Systemkomponente zugeordnet werden können. So kann ein anstehender und vom Bedienpersonal durchzuführender Rollenwechsel frühzeitig angezeigt werden. Das Bedienpersonal kann den Rollenwechsel ohne Verzögerung durchführen, was die Stillstandszeit der betreffenden Maschine verkürzt und letztendlich den Durchsatz erhöht. The above-mentioned operating parameters of the current production can be further differentiated into predictable or calculable (pending changes, upcoming maintenance work, requirements of downtime) and in sudden or changing (defect, which affects the functioning of the machine) operating parameters. It is also advantageous if the control device makes at least a part of the production parameters and / or information derived therefrom visible on a display device, on which the displayed parameters of the respective system component can be assigned. Thus, an upcoming and to be performed by the operator role change can be displayed early. Operators can perform reel change without delay, which shortens the downtime of the machine in question and ultimately increases throughput.
Es ist von großem Vorteil, wenn verschiedene, oder gar alle in dieser Druckschrift vorgestellte Verfahren von der Steuereinheit des Systems automatisiert ausgeführt werden. Hierzu kann die Steuervorrichtung entsprechend eingerichtet werden. Diese Einrichtung kann durch eine Programmierung vorgenommen werden. Diese Programmierung kann auch unter Verwendung von Datenträgern oder moderner Datenübermittlungsmethoden wie E-Mail, Chatting oder Fernwartungsmethoden vorgenommen werden. It is of great advantage if various, or even all presented in this document method by the control unit of the system are carried out automatically. For this purpose, the control device can be set up accordingly. This device can be made by programming. This programming can also be done using data carriers or modern data transmission methods such as e-mail, chatting or remote maintenance methods.

Fig. 1 zeigt eine Schlauchmaschine 1 als Bestandteil eines erfindungsgemäßen Systems. Gezeigt ist eine solche Maschine zum Herstellen eines vierlagigen Schlauches. Vier Lagen sind jedoch keine Beschränkung, es können auch Schläuche mit mehr oder mit weniger Lagen produzierbar sein. Die einzelnen Bahnen 6, 7 werden von hintereinander angeordneten und in Abwickeleinrichtungen 2, 3 gelagerten Materialrollen 4, 5 abgezogen. Es sind nur zwei Abwickeleinrichtungen dargestellt. Die Materialrollen 4, 5 sind in Gestellen 8, 9 drehbar gelagert. Die abgezogenen Bahnen 6, 7 laufen über Leitrollen zu den Vorzugseinrichtungen. Die Bahnen 6, 7, 10, 11 werden durch angetriebene Vorzugseinrichtungen vorgezogen, von denen jede aus der angetriebenen Vorzugswalze 12 und der den Umschlingungswinkel vergrößernden Leitwalze 13 besteht. Hinter den Vorzugswalzen 12, 13 ist eine die Bahn mit Nadellöchern versehende Einrichtung angeordnet, die aus einer Gegendruckwalze 14 besteht, über die die eingezogene Bahn läuft und an die eine Nadelwalze 15 anstellbar ist, die die Bahn entweder über ihre ganze Breite oder streifenmäßig mit Nadellöchern versieht, die der Entlüftung der aus den Bahnen hergestellten Säcken dienen. Nun läuft jede Papierbahn von der Nadelwalze zu der Messerwalze 16, die an eine Gegendruckwalze 17 anstellbar ist. Die Messerwalze 16 erzeugt eine Querperforation, die die spätere Abrisslinie bildet. Die Papierbahnen laufen daran anschließend in einen Ständer 18 ein, in dem die Bahnen 6, 7 und 10 beidseits der Querperforationen durch Klebstoffauftragswalzen 19 mit quer verlaufenden Klebstoffstreifen versehen werden. Nach dem Zusammenführen der Bahnen mittels der Umlenkrollen 20 laufen diese über Klebstoffauftragswalzen 21 , welche die Bahnen mit Klebestoffaufträgen in Längsrichtung versehen. Es schließt sich die Schlauchbildungsstation 22 an, welche im Wesentlichen Führungselemente wie etwa Führungsbleche umfasst, mit welchen die Außenränder der Bahnen umgeschlagen und übereinander gelegt werden. Der so gebildete Schlauch 23 läuft nun in ein Abreißwerk 24 ein, in dem der Schlauch 23 entlang der Querperforation reißt und auf diese Weise in Schlauchstücke 25 vereinzelt wird. Ein solches Abreißwerk ist beispielsweise aus der EP 0 711 724 A1 bekannt. Aus mehreren Schlauchstücken 25 werden nun in der Stapeleinrichtung 26 Schlauchstückstapel 27 gebildet, die über eine erste Transporteinrichtung 28 abgeführt werden. Fig. 1 shows a hose machine 1 as part of a system according to the invention. Shown is such a machine for producing a four-ply hose. However, four layers are not limitative; hoses with more or less layers can also be produced. The individual webs 6, 7 are withdrawn from successively arranged and in unwinding devices 2, 3 mounted material rolls 4, 5. Only two unwinding devices are shown. The material rolls 4, 5 are rotatably mounted in frames 8, 9. The withdrawn tracks 6, 7 run over guide rollers to the preference devices. The webs 6, 7, 10, 11 are pulled forward by driven preferred means, each of which consists of the driven feed roller 12 and the wrap angle-increasing guide roller 13. Behind the feed rollers 12, 13 there is arranged a web provided with pinholes which consists of a counterpressure roller 14 over which the drawn web runs and to which a needle roller 15 can be placed, which strips the web either over its entire width or in strips with pinholes which serves to vent the sacks made from the webs. Now, each paper web runs from the needle roller to the knife roller 16, which can be adjusted to a counter-pressure roller 17. The knife roller 16 creates a transverse perforation that forms the later tear line. The paper webs then run into a stand 18, in which the webs 6, 7 and 10 are provided on both sides of the transverse perforations by adhesive applicator rollers 19 with transverse adhesive strips. After merging the webs by means of the deflection rollers 20, these run over adhesive application rollers 21, which provide the webs with adhesive orders in the longitudinal direction. This is followed by the hose forming station 22, which essentially comprises guide elements, such as guide plates, with which the outer edges of the webs are folded over and laid one on top of the other. The tube 23 thus formed now enters a tear-off device 24, in which the tube 23 tears along the transverse perforation and is separated in this way into pieces of tubing 25. Such a tear-off device is known, for example, from EP 0 711 724 A1. From several pieces of tubing 25 26 pieces of tubing 27 are now formed in the stacking device, which are discharged via a first transport device 28.
Die Schlauchmaschine umfasst mehrere Walzen, die angetrieben sein können. Neben den bereits genannten Vorzugswalzen 12 können weitere Walzen als Antriebswalzen ausgebildet sein. Die Fertigungsgeschwindigkeit kann dabei über Drehgeber an den Antriebswalzen (nicht gezeigt) oder über Drehgeber an einer Umlenkwalze gemessen werden. Als Beispiel umfasst die Umlenkwalze 29 einen Drehgeber 30. Auch ist denkbar, die Transportgeschwindigkeit einer Bahn direkt zu messen. Der Umfang der Materialrollen 4 und 5 kann über Sensoren 31 , 32 gemessen werden. Darüber kann, bei Kenntnis des Durchmessers der Wickelhülsen 35, die Restmenge des Materials bestimmt und damit der Zeitpunkt des spätesten Rollenwechsels vorausbestimmt werden. Als Alternative bieten sich Drehgeber 33, 34 an, die die Drehgeschwindigkeiten der Materialrollen messen. Unter Berücksichtigung der Fertigungsgeschwindigkeit kann der Zeitpunkt des Rollenwechsels bestimmt werden. The tube machine includes a plurality of rollers that can be driven. In addition to the already mentioned feed rollers 12 further rollers may be formed as drive rollers. The production speed can be measured via rotary encoders on the drive rollers (not shown) or via rotary encoders on a deflection roller. As an example, the guide roller 29 includes a rotary encoder 30. It is also conceivable to measure the transport speed of a web directly. The circumference of the material rolls 4 and 5 can be measured via sensors 31, 32. In addition, with knowledge of the diameter of the cores 35, the remaining amount of the material determined and thus the time of the latest roll change can be predetermined. As an alternative, rotary encoders 33, 34 are available, which measure the rotational speeds of the material rolls. Taking into account the production speed, the time of the roll change can be determined.
Ein weiterer Sensor 36 bestimmt die Anzahl der Schlauchstücke 25 in dem Schlauchstückstapel 27. Die Daten der Sensoren und Drehgeber 30 - 34 und 36 können über eine Datenleitung 37 der Steuereinheit 38 zugänglich gemacht werden. Weitere Sensoren und/oder Messeinrichtungen an weiteren Stellen der Maschine sind denkbar, auch sie wären über die Datenleitung 37 an die Steuereinheit 38 angeschlossen. Die Steuereinheit 38 steuert nun über die Steuerleitung 39 die Antriebe an. Beispielhaft ist gezeigt, dass die Steuerleitung 39 zum Antrieb der Umlenkwalze 12 führt. A further sensor 36 determines the number of tube pieces 25 in the tube piece stack 27. The data of the sensors and rotary encoders 30-34 and 36 can be made accessible to the control unit 38 via a data line 37. Further sensors and / or measuring devices at other locations of the machine are conceivable, and they would also be connected to the control unit 38 via the data line 37. The control unit 38 now controls the drives via the control line 39. By way of example, it is shown that the control line 39 leads to the drive of the deflection roller 12.
Auch die erste Transporteinrichtung 28 wird hinsichtlich ihrer Transportgeschwindigkeit von der Steuereinrichtung 38 über eine Steuerleitung 40 gesteuert. Wenigstens ein Belegungssensor 41 kann vorgesehen sein, um den Füllungsgrad dieser ersten Transporteinrichtung 28 bestimmen zu können. Also, the first transport device 28 is in terms of their transport speed of the controller 38 via a control line 40 controlled. At least one occupancy sensor 41 can be provided in order to be able to determine the degree of filling of this first transport device 28.
Nicht gezeigt ist, dass zwischen den Abwickeleinrichtungen 2, 3 und den Vorzugswalzen 12 noch zumindest eine Druckmaschine angeordnet sein kann, die abgewickelte Bahnen, in der Regel eine der Bahnen, bedruckt. Auch an oder in dieser Druckmaschine können Betriebsparameter bestimmt oder berechnet werden. Dazu können Sensoren vorhanden sein, die zum Beispiel den Füllstand der Druckfarbe in den Farbtanks überwachen. Betriebsparameter der Druckmaschine können über nicht gezeigte Datenleitungen der Steuereinrichtung übermittelt werden. Diese Betriebsparameter können dann zum Einstellen oder zum Vorschlagen von Fertigungsgeschwindigkeiten von Maschinen herangezogen werden. Die Figur 2 zeigt eine Bodenlegemaschine 50, der über die erste Transporteinrichtung 28 Schlauchstückstapel 27 zugeführt werden. Die erste Transporteinrichtung 28 kann aus verschiedenen Elementen bestehen. So können mehrere Transporteinrichtungen vorgesehen sein. Hiervon können einige zum vertikalen Transport oder zur Änderung der Ausrichtung der Schlauchstücke, relativ zu ihrer Transportrichtung, dienen. Auch eine oder mehrere Lagerelemente können vorgesehen sein, in denen die Schlauchstücke gewisse Zeiten verweilen können. Ein solches Lagerelement ist beispielsweise in der EP 1 593 614 beschrieben. Die Bodenlegemaschine 50 übernimmt die Schlauchstücke 25 so, dass ihre Ausrichtung, das heißt die Ausrichtung der Längsklebenaht, quer zur Transportrichtung ist. Die Schlauchstücke 25 werden von einer Vereinzelungseinrichtung 51 , die, wie in der Figur 2 angedeutet, als Rotationsanleger ausgeprägt sein kann, einzeln von dem Schlauchstückstapel entnommen. Eine Ausricht- und Transportvorrichtung 52 transportiert die Schlauchstücke 25 weiter und sorgt gleichzeitig für eine gute Ausrichtung der Lage der Schlauchstücke 25. Ein Doppelbandförderer 53 übernimmt die einzelnen Schlauchstücke 25 und befördert diese zu den einzelnen Bearbeitungsstationen, die in bekannter Weise an einem oder beiden Enden der Schlauchstücke 25 Böden anformen. Dabei werden in einem ersten Schritt die Enden aufgezogen, so dass offene Bodenrechtecke unter Ausbildung von seitlichen Dreieckstaschen entstehen. Anschließend kann ein Ventilzettel 54 aufgeklebt werden. Dazu wird der Ventilzettel und/oder Bereiche des Schlauchstücks 25 mit Klebstoff aus einem so genannten Leimauftragswerk versehen. Die Ventilzettel 54 bestehen in der Regel aus Papier und entstehen durch Abschneiden einzelner Zettel von der Materialbahn 55, die als Materialbahnrolle 56 zur Verfügung gestellt wird. Analog zu den Materialbahnrollen 4 und 5 in der Schlauchmaschine 1 können an dieser Stelle Sensoren 57 und/oder Drehgeber 58 vorgesehen sein, die über Datenleitungen 59 mit der Steuereinheit 38 verbunden sind, um letztendlich den Zeitpunkt eines bevorstehenden Rollenwechsels im Voraus bestimmen zu können. Auch Komponenten des Leimauftragswerks, wie etwa ein Leimvorratsbehälter, können auch mit Sensoren ausgestattet sein. Die Steuereinheit 38 steuert über eine Steuerleitung 60 unter anderem die Umfangsgeschwindigkeit des Antriebsrads 61 des Doppelbandförderers 53 und damit die Fertigungsgeschwindigkeit der Bodenlegemaschine 50. Auch die Vorzugsgeschwindigkeit der Materialbahn 55 wird auf eine solche, allerdings nicht dargestellte Art und Weise gesteuert. It is not shown that between the unwinding devices 2, 3 and the feed rollers 12 at least one printing press can still be arranged, the unwound webs, usually one of the webs, printed. Also on or in this printing machine operating parameters can be determined or calculated. These sensors may be present, for example, monitor the level of the ink in the color tanks. Operating parameters of the printing press can be transmitted to the control device via data lines (not shown). These operating parameters can then be used to set or propose machine production speeds. FIG. 2 shows a floor laying machine 50, which is supplied with hose piece stacks 27 via the first transport device 28. The first transport device 28 may consist of different elements. Thus, a plurality of transport devices can be provided. Some of these may be used for vertical transport or to change the orientation of the tube pieces relative to their direction of transport. Also, one or more bearing elements may be provided, in which the hose pieces can dwell certain times. Such a bearing element is described for example in EP 1 593 614. The floor laying machine 50 takes over the hose pieces 25 so that their orientation, that is the orientation of the longitudinal adhesive seam, is transverse to the transport direction. The tube pieces 25 are removed individually from the tube piece stack by a separating device 51, which, as indicated in FIG. 2, can be designed as a rotary feeder. An alignment and transport device 52 transports the tube pieces 25 on and at the same time ensures a good alignment of the position of the tube pieces 25th A double belt conveyor 53 takes over the individual pieces of tubing 25 and conveys them to the individual processing stations, which in a known manner at one or both ends of the pieces of tubing 25 form soils. In this case, the ends are raised in a first step, so that open Bodenrechtecke arise to form lateral triangular pockets. Subsequently, a valve leaflet 54 are glued. For this purpose, the valve sheet and / or regions of the hose piece 25 are provided with adhesive from a so-called glue applicator. The valve pad 54 are usually made of paper and are created by cutting individual pieces of the material web 55, which is provided as web roll 56 available. Analogous to the web rolls 4 and 5 in the tube machine 1 sensors 57 and / or rotary encoder 58 may be provided at this point, which are connected via data lines 59 to the control unit 38 to ultimately determine the time of an upcoming roll change in advance can. Components of the glue applicator, such as a glue reservoir, may also be equipped with sensors. The control unit 38 controls via a control line 60, inter alia, the peripheral speed of the drive wheel 61 of the double belt conveyor 53 and thus the production speed of the floor laying machine 50. Also, the preferred speed of the web 55 is controlled in such, but not shown manner.
Nach dem Aufkleben des Ventilzettels 54 wird der Boden zugelegt und gegebenenfalls verklebt. Schließlich kann noch ein Bodendeckblatt 62 zur Verstärkung des fertigen Bodens aufgeklebt werden. Die Bodendeckblätter 62 werden dazu von einer Materialbahn 63, die von einer Materialbahnrolle 64 zur Verfügung gestellt wird, vereinzelt. Wie im Fall der Ventilzettel 54 sind auch hier entsprechende Sensoren, Drehgeber, Datenleitungen und/oder Steuerleitungen vorgesehen, was aber der Einfachheit halber nicht gezeigt wird. After sticking the valve leaflet 54, the soil is added and possibly glued. Finally, a bottom cover sheet 62 can be glued to reinforce the finished floor. The bottom cover sheets 62 are for this purpose of a material web 63, which is provided by a web roll 64, isolated. As in the case of the valve pad 54, corresponding sensors, rotary encoders, data lines and / or control lines are also provided here, but this is not shown for the sake of simplicity.
Die so aus Schlauchstücken 25 gefertigten Säcke 65 werden von einer zweiten Transporteinrichtung 66 übernommen und abtransportiert. Oft werden die Säcke 65 dazu in Schuppen (siehe Figur 3) angeordnet. Die Schuppen werden, wie in der Figur 3 zu erkennen ist, von der zweiten Transporteinrichtung an eine so genannte Ablageeinrichtung 67 übergeben. Diese Ablageeinrichtung 67 transportiert die Säcke 65 über bestimmte Wege und nimmt dabei eine Verpressung der frisch hergestellten Böden vor, um für eine dauerhaft starke Verklebung zu sorgen. Die Transportstrecke in der Ablageeinrichtung ist verhältnismäßig lang, um ein ausreichendes Abtrocknen der Verklebung zu ermöglichen. Die zweite Transporteinrichtung 66 kann wiederum in mehrere Transport- und/oder Lagereinrichtungen untergliedert sein. Nach dem Durchlaufen der Ablageeinrichtung 67 gelangen die Säcke 65 auf eine dritte Transporteinrichtung 68, welche die Säcke 65 zu einer nicht gezeigten Schuppenzähl- und Trenneinrichtung transportiert. Diese trennt die Schuppen und ordnet die Säcke 65 zu Sackstapeln 69 mit einer bestimmten Anzahl an Säcken 65 an. Eine solche Schuppenzähl- und Trennstation ist beispielsweise in der DE 10 2004 055 325 B4 gezeigt und erläutert. Der Schuppenzähl- und Trennstation folgen oft noch eine oder mehrere weitere Transport- und/oder Lagereinrichtungen, beispielsweise solche, wie sie für den Bereich zwischen der Schlauchmaschine 1 und der Bodenlegemaschine 50 beschrieben wurden. In dem Bereich hinter der Schuppenzähl- und Trennstation werden oft stichprobenartig einzelne Säcke oder Sackstapel entnommen, einer Qualitätskontrolle unterzogen und anschließend wieder in die Transportkette eingefügt. Auch die Zeit der Kontrolle kann als Lagerung angesehen werden. The bags 65 produced in this way from hose pieces 25 are taken over by a second transport device 66 and transported away. Often, the sacks 65 are arranged in sheds (see FIG. 3). As can be seen in FIG. 3, the flakes are transferred by the second transport device to a so-called depositing device 67. This depositing device 67 transports the sacks 65 via certain paths and thereby takes a compression of the freshly prepared soils in order to ensure a permanently strong bonding. The transport distance in the storage device is relatively long to allow sufficient drying of the bond. The second transport device 66 can in turn be subdivided into a plurality of transport and / or storage facilities. After passing through the depositing device 67, the sacks 65 reach a third transport device 68, which transports the sacks 65 to a scissor counting and separating device (not shown). This separates the scales and arranges the sacks 65 to bag stacks 69 with a certain number of bags 65 at. Such a scanning counting and separating station is shown and explained, for example, in DE 10 2004 055 325 B4. The scissor counting and separating station often still follow one or more further transport and / or storage facilities, such as those described for the area between the hose machine 1 and the floor laying machine 50. In the area behind the screed counting and separating station, individual sacks or sacks of piles are often taken randomly, subjected to quality control and then re-inserted into the transport chain. Also the time of the control can be regarded as storage.
Die Figur 4 zeigt eine Palettiermaschine 70 als ein Ausführungsbeispiel einer Vorrichtung, mit welcher eine Vielzahl von Säcken zu einem transportierbaren Sackverbund angeordnet werden können. Eine andere solche Vorrichtung ist etwa eine Einrichtung, in der geschuppt angeordnete Säcke unter Zuhilfenahme von Bändern oder Streifen zu Rollen aufgewickelt werden. Die Palettiermaschine 70 umfasst eine vierte Transporteinrichtung 71 , die die Sackstapel 69 in den Bewegungsbereich einer Greifeinrichtung 72 bringt. Die Greifeinrichtung 72 ergreift jeweils einen Sackstapel 69 und ordnet ihn auf einer Palette 73 an. Auch in der Palettiermaschine können Sensoren vorgesehen sein, die beispielsweise die aktuelle Belegung der Palette 72 überwachen. Die Sensoren sind über nicht gezeigte Datenleitungen mit der Steuereinheit 38 verbunden. Die Steuereinheit 38 kann unter Berücksichtigung von Betriebsparametern und Fertigungsgeschwindigkeiten anderer Maschinen die Palettiergeschwindigkeit der Palettiermaschine vorschlagen und/oder einstellen. 4 shows a palletizing machine 70 as an embodiment of a device with which a plurality of bags can be arranged to form a transportable bag composite. Another such device is, for example, a device in which bags arranged in a scaled state are wound into rolls with the aid of bands or strips. The palletizing machine 70 comprises a fourth transport device 71, which brings the sack stacks 69 into the movement range of a gripping device 72. The gripping device 72 engages in each case a sack stack 69 and arranges it on a pallet 73. Sensors may also be provided in the palletizing machine which monitor, for example, the current occupancy of the pallet 72. The Sensors are connected to the control unit 38 via data lines, not shown. The control unit 38 can propose and / or adjust the palletizing speed of the palletizing machine taking into account operating parameters and production speeds of other machines.
