In both cases, for example, soiling can lead to more energy being expended than usual.

Description

Die Erfindung betrifft ein System zum Betreiben einer Verpackungsanlage für Produkte, insbesondere Tabakartikel, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a system for operating a packaging installation for products, in particular tobacco articles, according to the preamble of claim 1.

In Zeiten zunehmender Energiepreise verlangen Käufer von Verpackungsanlagen, Verpackungsmaschinen und von einzelnen Aggregaten für solche Maschinen, dass diese Organe energiesparend betrieben werden können. Es wird daher seit längerem darauf geachtet, dass die Organe im Betriebszustand allgemein möglichst wenig Energie verbrauchen. Weiterhin ist es üblich Organe so zu dimensionieren, dass sie normalerweise mit einem Auslastungsgrad betrieben werden, in dem das Organ einen geringen Energieverbrauch aufweist.In times of increasing energy prices, buyers of packaging equipment, packaging machines and individual units for such machines require that these organs can be operated in an energy-saving manner. It has therefore long been taken to ensure that the organs generally consume as little energy as possible during operation. Furthermore, it is common to dimension organs so that they are normally operated at a utilization level in which the organ has a low energy consumption.

Aus WO 2011/113506 A1 ist ein Verfahren zum Betrieb oder Steuern eines Schrumpftunnels bekannt, bei dem vorgeschlagen wird, einzelne Organe bei Betriebsstörungen in einen Standbymodus zu versetzen, um Energie zu sparen.Out WO 2011/113506 A1 For example, a method for operating or controlling a shrink tunnel is known in which it is proposed to put individual organs in a standby mode in the event of malfunctions in order to save energy.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde Systeme der eingangs genannten Art in Richtung weiterer Energieeinsparung zu verbessern. Der Begriff Energieeinsparung bezeichnet dabei alle Maßnahmen, die die Menge verbrauchter Energie verringern.On this basis, the invention has the object to improve systems of the type mentioned in the direction of further energy savings. The term energy saving refers to all measures that reduce the amount of energy consumed.

Zur Lösung dieser Aufgabe weist ein erfindungsgemäßes System die Merkmale des Anspruchs 1 auf.To solve this problem, an inventive system has the features of claim 1.

Als Energieeffizienz wird im Allgemeinen die Effizienz des Einsatzes von Energie verstanden, also das Verhältnis von Nutzen zum Energieaufwand. Bezogen auf eine Verpackungsanlage wird unter Energieeffizienz der spezifische Energieverbrauch verstanden, also die für das Verpacken eines Produkts benötigte Energie.Energy efficiency is generally understood as the efficiency of the use of energy, ie the ratio of benefits to energy expenditure. Related to one Under energy efficiency, packaging equipment is understood to be the specific energy consumption, ie the energy required for the packaging of a product.

Unter dem Betriebsmodus wird im Rahmen dieser Anmeldung der Zustand der Organe verstanden, in dem sie sich bei regulärem bzw. üblichem Betrieb der Verpackungsanlage befinden. Dabei muss nicht zwangsläufig nur ein einziger Betriebsmodus existieren, sondern es können mehrere Betriebsmodi existieren, beispielsweise für unterschiedliche zu verpackende bzw. in der Anlage zu handhabende Produkte.Under the operating mode is understood in the context of this application, the state of the organs in which they are in regular or normal operation of the packaging system. In this case, not only a single mode of operation necessarily exists, but several modes of operation may exist, for example for different products to be packed or handled in the system.

Unter einem Energiesparmodus wird im Rahmen dieser Anmeldung ein Zustand verstanden in dem die Organe weniger Energie als im jeweiligen Betriebsmodus verbrauchen. Dies kann durch (komplette) Abschaltung der Organe erfolgen oder aber auch durch teilweise Reduzierung des Energieverbrauchs. In der Praxis kann jedes Organ verschiedene Energiesparmodi aufweisen, mit unterschiedlichem jeweiligem Energieverbrauch, bis zur Komplettabschaltung als Energiesparmodus mit dem geringsten bzw. keinem Energieverbrauch.Under a power-saving mode is understood in the context of this application, a state in which the organs consume less energy than in the respective operating mode. This can be done by (complete) shutdown of the organs or by partially reducing the energy consumption. In practice, each organ may have different energy saving modes, with different respective energy consumption, until complete shutdown as the energy saving mode with the least or no energy consumption.

Sofern für die Organe unterschiedliche Betriebsmodi existieren - beispielsweise für verschiedene Produkte - kann es denkbar sein, dass der Betriebsmodus für ein Produkt einem Energiesparmodus für ein anderes Produkt entspricht.If different modes of operation exist for the organs - for example, for different products - it may be conceivable that the operating mode for one product corresponds to a power saving mode for another product.

Gemäß einer bevorzugten Weiterbildung der Erfindung kann vorgesehen sein, dass in der Steuereinheit Programme zur Steuerung der Verpackungsanlage und/oder deren Organe hinterlegt sind, wobei die Programme bestimmten Betriebszuständen der Verpackungsanlage und/oder deren Organen zugeordnet sind.According to a preferred development of the invention it can be provided that programs for controlling the packaging installation and / or their organs are stored in the control unit, the programs being assigned to specific operating states of the packaging installation and / or their organs.

Es kann demnach eine Steuereinheit vorgesehen sein, die Programme zur Steuerung oder Regelung der Organe aufweist im Hinblick auf die Betriebs- und Energiesparmodi bzw. den Energieverbrauch. Weiterhin ist vorgesehen, dass diese Programme bestimmten Betriebszuständen zugeordnet sind.Accordingly, a control unit may be provided which has programs for controlling or regulating the organs with regard to the operating and energy-saving modes or the energy consumption. Furthermore, it is provided that these programs are assigned to specific operating states.

Denkbar wäre zum Beispiel ein Programm für den "normalen Betrieb", in dem alle Organe im Betriebsmodus betrieben werden. Gegebenenfalls können mehrere Programme für den "normalen Betrieb" existieren, z.B. in Abhängigkeit vom zu verpackenden Produkt. Denkbar sind dabei Programme für bestimmte Produkte, bei denen Organe teilweise in einen Energiesparmodus versetzt werden oder sogar abgeschaltet werden, weil sie bei der Verpackung des Produkts in geringerem Maße oder gar nicht benötigt werden.For example, a program for "normal operation" in which all organs are operated in operating mode would be conceivable. If necessary, several programs for the "normal operation" exist, for example, depending on the product to be packaged. Conceivable are programs for certain products, in which organs are partially put into a power-saving mode or even switched off, because they are required in the packaging of the product to a lesser extent or not at all.

Denkbar ist insbesondere der Betrieb von Heizeinrichtungen mit niedriger Temperatur nach Maßgabe des zu verpackenden Produkts.In particular, it is conceivable to operate low-temperature heaters in accordance with the product to be packaged.

Weiterhin ist denkbar, dass die Organe nach Maßgabe der Produktionsgeschwindigkeit gesteuert bzw. geregelt werden. Denkbar wäre, dass bei niedriger Produktionsgeschwindigkeit der Verpackungsanlage die Heizeinrichtungen mit geringerer Temperatur betrieben werden und umgekehrt.Furthermore, it is conceivable that the organs are controlled or regulated in accordance with the production speed. It would be conceivable that at low production speed of the packaging system, the heaters are operated at a lower temperature and vice versa.

Insbesondere wäre es denkbar die Anlage nach Maßgabe der Arbeitsgeschwindigkeit eines Bedieners zu steuern bzw. zu regeln. Auf diese Weise könnte beispielsweise bei der Einarbeitung von Bedienern Energie gespart werden. Es könnte auf diese Weise auch die allgemeine Arbeitsgeschwindigkeit der Bediener einer Anlage berücksichtigt werden. Denkbar ist dann z.B., dass bestimmte Anlagen individuell entsprechend der Bediener mit höheren oder niedrigeren Produktionsgeschwindigkeiten betrieben werden, um den spezifischen Energieverbrauch so gering wie möglich zu halten.In particular, it would be conceivable to control or regulate the system in accordance with the operating speed of an operator. In this way, for example, could be saved in the training of operators energy. It could also be considered in this way, the general operating speed of the operator of a plant. It is then conceivable, for example, that certain systems are operated individually according to the operator with higher or lower production speeds in order to keep the specific energy consumption as low as possible.

In der Praxis dürfte eine große Bedeutung auch Programmen zukommen, die bei Betriebsunterbrechungen, wie z.B. Pausen, Störungen, bei Wartungsarbeiten, nach Feierabend, an Wochenenden, in Werksferien etc. zum Einsatz kommen. Hier ist es denkbar, dass je nach Länge der Unterbrechung verschiedene Programme zur Verfügung stehen, um den Energieverbrauch der Organe zu senken.In practice, great importance is also to be attached to programs which can be used in the event of business interruptions, such as Breaks, malfunctions, during maintenance, after hours, on weekends, in factory holidays etc. are used. Here it is conceivable that, depending on the length of the interruption, various programs are available to reduce the energy consumption of the organs.

Hinsichtlich der Auswahl der Programme in der Steuereinheit sind verschiedene Möglichkeiten denkbar, die einzeln oder kumulativ in beliebiger Kombination verwirklicht sein können:

  • die Programme können direkt (manuell) ausgewählt werden,
  • die Programme können automatisch ausgewählt werden.
With regard to the selection of the programs in the control unit, various possibilities are conceivable which can be implemented individually or cumulatively in any combination:
  • the programs can be selected directly (manually),
  • the programs can be selected automatically.

Bei der automatischen Auswahl kommt zum einen eine zeitgesteuerte Auswahl in Frage, mit der planmäßige Änderungen des Betriebszustands der Organe berücksichtigt werden können, wie z.B. Pausen, planmäßige Wartungsarbeiten, Feierabend, Schichtwechsel, Wochenenden, Werksferien etc.In the automatic selection is on the one hand a time-controlled selection in question, with the planned changes in the operating state of the institutions can be considered, such as breaks, scheduled maintenance, closing time, shift changes, weekends, plant holidays, etc.

Denkbar ist aber zum anderen auch eine automatische Auswahl der Programme anhand des Betriebszustands der Verpackungsanlage und/oder deren Organe.On the other hand, an automatic selection of the programs on the basis of the operating state of the packaging installation and / or its organs is also conceivable.

Insbesondere für eine automatische Auswahl der Programme aber auch für statistische Zwecke bzw. für eine manuelle Auswertung kann es sinnvoll sein, dass die Betriebszustände und/oder Betriebsunterbrechungen der Verpackungsanlage und/oder deren Organe durch die Steuereinheit erfasst werden.In particular, for an automatic selection of the programs but also for statistical purposes or for a manual evaluation, it may be useful that the operating conditions and / or service interruptions of the packaging system and / or its organs are detected by the control unit.

Weiterhin ist vorzugsweise vorgesehen, dass der Energieverbrauch der Verpackungsanlage und/oder deren Organe erfasst werden. Vorzugsweise erfolgt die Erfassung in Abhängigkeit von einem oder mehreren der folgenden Faktoren:

  • Betriebsmodus der Verpackungsanlage (10) und/oder deren Organe,
  • Zeitpunkt,
  • Produkt,
  • Bediener bzw. Bedienmannschaft.
Furthermore, it is preferably provided that the energy consumption of the packaging installation and / or its organs are detected. Preferably, the detection is dependent on one or more of the following factors:
  • Operating mode of the packaging installation (10) and / or its organs,
  • Time,
  • Product,
  • Operator or operating team.

Die erfassten Daten können dann beispielsweise in der Steuereinheit (27), der Maschinensteuerung oder einem Linienrechner gespeichert werden.The acquired data can then be stored, for example, in the control unit (27), the machine control or a line computer.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die in der Steuereinheit hinterlegten Programme aufgrund von Aufzeichnungen des Betriebszustands und/oder des Energieverbauchs und/oder der Betriebsunterbrechungen der Verpackungsanlage und/oder einer oder mehrerer Organe automatisch angepasst werden. In diesem Fall "lernt" das System aus den aufgezeichneten Daten und kann hieraus die Programme selbsttätig optimieren.According to a preferred embodiment of the invention, it is provided that the programs stored in the control unit are automatically adjusted on the basis of records of the operating state and / or the energy consumption and / or the service interruptions of the packaging installation and / or one or more organs. In this case, the system "learns" from the recorded data and can automatically optimize the programs from this.

Beispielsweise kann ein selbstlernendes System erkennen, dass bestimmte Störungen der Organe zu Betriebsunterbrechungen gewisser Länge führen. Sobald ausreichende Daten vorliegen, kann statistisch bzw. durch Wahrscheinlichkeitsberechnungen ermittelt werden, wie lang die jeweilige Unterbrechung voraussichtlich dauern wird, sodass die entsprechenden Programme entsprechend durch die Steuereinheit angepasst werden.For example, a self-learning system can detect that certain disorders of the organs lead to business interruptions of a certain length. Once sufficient data is available, it can be determined statistically or by probability calculations how long the respective interruption is likely to take, so that the corresponding programs are adapted accordingly by the control unit.

Darüber hinaus ist denkbar, dass neue Anlässe für Betriebsunterbrechungen durch die Steuereinheit erkannt werden und entsprechende Programme generiert werden, um auf diese Betriebsunterbrechung zu reagieren.In addition, it is conceivable that new occasions for business interruptions are detected by the control unit and corresponding programs are generated in order to respond to this business interruption.

Als Beispiel könnte man sich vorstellen, dass in einer Verpackungsanlage für Zigaretten erstmalig ein Aggregat eines Faltrevolvers ausfällt, wobei zu diesem Fehler noch keine Programmierung existiert. Das System würde den neu aufgetretenen Fehler erkennen und in der Folge registrieren welche Organe der Anlage aufgrund dieses Fehlers angehalten oder mit geringerer Leistung betrieben werden können bzw. müssen. Weiterhin würde das System die Zeit bis zur Behebung des Fehlers registrieren und könnte dann eine neue Regel bzw. ein neues Programm generieren, das bei erneutem Eintritt des Fehlers abgerufen wird. Bei jedem zukünftigen Auftritt der Betriebsunterbrechung würden die Auswirkungen erkannt und das Programm gegebenenfalls angepasst.As an example, one could imagine that for the first time an aggregate of a folding turret fails in a packaging plant for cigarettes, whereby no error has yet been given for this defect Programming exists. The system would detect the newly occurring fault and subsequently register which organs of the system can be stopped or operated with less power due to this fault. Furthermore, the system would register the time until the error was remedied and could then generate a new rule or program which will be called upon re-occurrence of the error. Any future outage appearance would detect the effects and adjust the program if necessary.

Es versteht sich, dass diese Vorgehensweise nicht nur bei Störungen bzw. Fehlern zum Einsatz kommen kann, sondern auch bei planmäßigen Eingriffen in den Betriebsablauf, wie z.B. beim Markenwechsel, Produktwechsel, Wartungsarbeiten, etc.It goes without saying that this procedure can be used not only in the event of faults or errors, but also in the case of planned interventions in the operating sequence, such as, for example, brand change, product change, maintenance, etc.

Weitere Besonderheiten betreffen konstruktive Lösungen bei der Versetzung von Organen in einen Energiesparmodus.Other peculiarities relate to constructive solutions in the displacement of organs in a power-saving mode.

Die Erfindung wird nachfolgend anhand einer Verpackungsanlage 10 für Tabakartikel exemplarisch erläutert. Die Verpackungsanlage 10 beinhaltet im gezeigten Ausführungsbeispiel eine gesamte Verpackungslinie von der Herstellung der Zigaretten bis zur Verpackung von Gebindepackungen.The invention is explained below by way of example with reference to a packaging installation 10 for tobacco products. In the exemplary embodiment shown, the packaging installation 10 includes an entire packaging line from the production of the cigarettes to the packaging of bundle packs.

Es versteht sich, dass es sich bei einer Verpackungsanlage 10 nicht zwangläufig um eine ganze Verpackungslinie handeln muss. Eine Verpackungsanlage 10 kann auch lediglich eine einzige Verpackungsmaschine bzw. ein einziges Verpackungsaggregat beinhalten.It goes without saying that a packaging installation 10 does not necessarily have to be an entire packaging line. A packaging system 10 may also include only a single packaging machine or a single packaging unit.

Des Weiteren versteht sich, dass die Erfindung nicht nur im Zusammenhang mit der Verpackung von Tabakartikeln, wie Zigaretten, Zigarillos oder dergleichen zum Einsatz kommen kann, sondern auch bei anderen Produkten, wie beispielsweise Hygieneprodukten.Furthermore, it is understood that the invention can be used not only in connection with the packaging of tobacco articles, such as cigarettes, cigarillos or the like, but also in other products, such as hygiene products.

Die Verpackungsanlage 10 gemäß Fig. 1 verfügt über eine Reihe von Verpackungsmaschinen, die das herzustellende Produkt bzw. Zwischenprodukt während der Bearbeitung innerhalb der Verpackungsanlage durchläuft. Jede Verpackungsmaschine wiederum weist eine Reihe von Aggregaten auf, die wiederum gesteuert bzw. geregelt werden können. Insofern wird im Folgenden zur sprachlichen Vereinfachung stets von Organen der Verpackungsanlage 10 die Rede sein. Dieser Terminus umfasst alle steuerbaren bzw. regelbaren Bestandteile der Verpackungsanlage 10, also letztendlich die Verpackungsmaschinen, deren Aggregate, Sub-Aggregate etc.The packaging system 10 according to Fig. 1 has a number of packaging machines that pass through the product or intermediate to be manufactured during processing within the packaging plant. Each packaging machine in turn has a number of aggregates, which in turn can be controlled or regulated. In this respect, in the following textual simplification will always be the organs of the packaging system 10. This term includes all controllable or controllable components of the packaging installation 10, ie ultimately the packaging machines, their aggregates, sub-aggregates, etc.

In dem in Fig. 1 gezeigten Ausführungsbeispiel einer Verpackungsanlage 10 folgen folgende Organe innerhalb der Verpackungslinie bzw. des Verpackungsprozesses aufeinander:

  • Maker 11,
  • Filteransetzer 12,
  • Zigarettenspeicher 13,
  • Hinge-Lid-Packer 14,
  • Zuschnittmagazin 15,
  • Packungsspeicher 16,
  • Cellophaniermaschine 17,
  • Stangenpacker 18,
  • Kartonpacker 19.
In the in Fig. 1 In the exemplary embodiment of a packaging installation 10, the following organs follow one another within the packaging line or the packaging process:
  • Maker 11,
  • Filter inserter 12,
  • Cigarette storage 13,
  • Hinge-lid packer 14,
  • Blank magazine 15,
  • Packet memory 16,
  • Cellophaning machine 17,
  • Rod packer 18,
  • Carton packer 19.

Seitlich neben der Verpackungslinie ist ein Bobinenlager 20 angeordnet, mit Verpackungsmaterialien für die einzelnen Organe der Verpackungsanlage 10. Mittels einer Bobinenversorgung 21 sind die Verpackungsmaterialien den einzelnen Organen zuführbar.On the side next to the packaging line, a reel storage 20 is arranged, with packaging materials for the individual organs of the packaging installation 10. By means of a reel supply 21, the packaging materials can be supplied to the individual organs.

Den Organen der Verpackungsanlage 10 sind jeweils Maschinensteuerungen 22 zugeordnet, zur Steuerung der jeweiligen Maschine bzw. des jeweiligen Organs. Diese sind über Steuerleitungen 23 mit einem Hauptrechner 24 verbunden. Der Hauptrechner 24 wiederum kann über Leitungen 25, 26 mit dem Internet und/oder dem Intranet verbunden sein.The organs of the packaging system 10 are each associated with machine controls 22 for controlling the respective machine or the respective organ. These are connected via control lines 23 to a host computer 24. The main computer 24 in turn can be connected via lines 25, 26 to the Internet and / or the intranet.

An einem Produktionsort können mehrere solcher Verpackungsanlagen 10 betrieben werden, die gegebenenfalls über die Leitungen 25 zum Intranet miteinander im Verbund gesteuert werden können. Denkbar ist auch eine Koppelung mehrerer Verpackungsanlagen 10 über das Intranet und/oder das Internet, um von einer oder mehreren zentralen Stellen Verpackungsanlagen 10 an einem oder mehreren Standorten steuern, regeln, kontrollieren oder auswerten zu können.At a production location, a plurality of such packaging systems 10 can be operated, which can optionally be controlled together via the lines 25 to the intranet in the network. It is also conceivable to couple a plurality of packaging installations 10 via the intranet and / or the Internet in order to be able to control, regulate, control or evaluate packaging installations 10 at one or more central locations from one or more central locations.

Zur Steigerung der Energieeffizienz der Verpackungsanlage 10 bzw. deren Organe ist eine Steuerungseinheit 27 vorgesehen. Die Steuerungseinheit 27 kann als separate Vorrichtung verwirklicht und mit der Verpackungsanlage 10 über die Leitungen 25, 26 verbunden sein oder im Hauptrechner 24 angeordnet sein. In der Steuereinheit 27 sind vorzugsweise verschiedene Programme zum Betrieb der Verpackungsanlage 10 gespeichert. Die Programme sehen je nach Einsatzweck verschiedene Konfigurationen für die Organe der Verpackungsanlage 10 vor.To increase the energy efficiency of the packaging system 10 and its organs, a control unit 27 is provided. The control unit 27 can be realized as a separate device and be connected to the packaging installation 10 via the lines 25, 26 or arranged in the main computer 24. Various programs for operating the packaging installation 10 are preferably stored in the control unit 27. The programs provide different configurations for the organs of the packaging installation 10, depending on the purpose of use.

Ein Beispiel eines ersten Programms für den Fall einer Betriebsunterbrechung ist in Fig. 7 gezeigt. In der linken Spalte des Diagramms sind einzelne Organe der Verpackungsanlage 10 grafisch dargestellt, daneben findet sich jeweils die Konfiguration in Abhängigkeit von der Länge der Betriebsunterbrechung. Im vorliegenden Fall ist vorgesehen, dass die Temperatur einer Schrumpfheizung 28 bei kurzen Unterbrechungen auf eine Temperatur von 50°C abgesenkt wird, bei einer länger dauernden Betriebsunterbrechung wird die Temperatur auf 30°C abgesenkt und schließlich bei langer Unterbrechung wird die Schrumpfheizung 28 ausgestellt. Vorzugsweise wird bei der Absenkung der Temperatur auch die Länge der zu erwartenden Betriebsunterbrechung berücksichtigt. Insbesondere soll die Temperatur nur soweit abgesenkt werden, dass sie bis zum erwarteten Ende der Betriebsunterbrechung wieder auf die Betriebstemperatur angehoben werden kann, sodass die Betriebsunterbrechung nicht durch das Absenken der Temperatur verlängert wird.An example of a first program in the event of a business interruption is in Fig. 7 shown. In the left column of the diagram, individual organs of the packaging installation 10 are shown graphically, in addition, there is in each case the configuration depending on the length of the business interruption. In the present case, it is provided that the temperature of a shrinkage heater 28 is lowered at short interruptions to a temperature of 50 ° C, with a longer interruption of the operation, the temperature is lowered to 30 ° C and finally at long Interruption, the shrink heater 28 is issued. Preferably, when lowering the temperature, the length of the expected service interruption is taken into account. In particular, the temperature should be lowered only to the extent that it can be raised again to the operating temperature until the expected end of the interruption, so that the business interruption is not prolonged by the lowering of the temperature.

Entsprechende Konfigurationen sind für einen Heißleimvorratsbehälter 29, einen Monitor 30, eine Maschinenbeleuchtung 31, einen Notaus-Schalter 32, einen Servomotor 33, ein Vakuumgebläse 34, eine Kamerakontrolle 35 und eine Laserbedruckung 36 vorgesehen.Corresponding configurations are provided for a hot glue reservoir 29, a monitor 30, a machine lighting 31, an emergency stop switch 32, a servo motor 33, a vacuum blower 34, a camera control 35 and a laser print 36.

Darüber hinaus kann in einem Programm natürlich auch die Konfiguration für den "normalen" Betrieb der Organe hinterlegt sein. Die neben den Symbolen in Fig. 7 ausgeführten Konfigurationen der Organe stehen dann für die verschiedenen Energiesparmodi derselben.In addition, in a program, of course, the configuration for the "normal" operation of the organs be deposited. The next to the icons in Fig. 7 executed configurations of the organs then stand for the different energy-saving modes of the same.

Die Steuereinheit 27 ist im vorliegenden Fall dazu eingerichtet die Programme einzurichten, anzuzeigen und auszuwählen. Wie bereits eingangs geschildert ist dies dadurch möglich, dass die Organe mit den jeweiligen Maschinensteuerungen 22 und diese mit der Steuereinheit 27 verbunden sind. Fig. 2 zeigt als weitere Organe der Verpackungsanlage 10 noch einen Schaltschrank 37 und die Cellophaniermaschine 17.In the present case, the control unit 27 is set up to set up, display and select the programs. As already mentioned, this is possible because the organs are connected to the respective machine controls 22 and these are connected to the control unit 27. Fig. 2 shows as a further organs of the packaging system 10 nor a cabinet 37 and the Cellophanier 17th

Die Auswahl der Programme kann wie in Fig. 2 angedeutet auf drei verschiedene Arten erfolgen, nämlich

  • manuell
  • automatisch und zeitgesteuert
  • automatisch nach Maßgabe des Betriebszustands.
The selection of programs can be as in Fig. 2 indicated in three different ways, namely
  • manually
  • automatic and timed
  • automatically according to the operating status.

Diese drei Methoden sind in Fig. 2 durch entsprechende Symbole in der Steuereinheit 27 angedeutet.These three methods are in Fig. 2 indicated by corresponding symbols in the control unit 27.

Einen einfachen Fall stellt die manuelle Auswahl der Programme dar. Durch einen Bediener können an einer Steuereinheit 27 die einzelnen Programme ausgewählt werden: Dies kann beispielsweise in Abhängigkeit von dem Betriebszustand der Verpackungsanlage 10 erfolgen, in Abhängigkeit von dem zu fertigenden Produkt oder in Abhängigkeit von sonstigen Randbedingungen.A simple case is the manual selection of programs. By an operator, the individual programs can be selected on a control unit 27: This can, for example, depending on the operating state of Packaging system 10, depending on the product to be manufactured or in dependence on other boundary conditions.

Bei Eintreten einer Störung, die zu einer Betriebsunterbrechung führt, kann der Bediener an der Steuereinheit 27 ein entsprechendes Programm wählen, das dann einzelne oder mehrere oder alle Organe in einen Energiesparmodus schaltet. Dieser Energiesparmodus kann konstant sein bis das Programm beendet oder wie in Fig. 7 gezeigt zeitabhängig sein.Upon the occurrence of a fault that leads to an interruption in operation, the operator at the control unit 27 can select a corresponding program, which then switches one or more or all organs into a power-saving mode. This energy saving mode can be constant until the program finishes or as in Fig. 7 be shown time-dependent.

Die zeitgesteuerte Programmierung der Steuereinheit 27 hingegen ermöglicht eine automatische Berücksichtigung von vorgegebenen Betriebsunterbrechungen, wie im Fall von Pausen, Schichtwechseln, zu Feierabend, an Wochenenden, in Betriebsferien oder dergleichen. Auch für planmäßig durchzuführende Wartungsarbeiten können solche zeitgesteuerten Programme zum Einsatz kommen.The time-controlled programming of the control unit 27, however, allows automatic consideration of predetermined interruptions in operation, such as in the case of breaks, shift changes, at closing time, on weekends, company holidays or the like. Also for scheduled maintenance work such time-controlled programs can be used.

Grundsätzlich soll bei Betriebsunterbrechungen die Zeit berücksichtigt werden, die benötigt wird, um die Aggregate wieder in den Betriebszustand zu bringen. Dies gilt insbesondere für die Zeit, die zum Aufheizen von Siegelorganen, Leimleitungen, Leimdüsen, Trockenrädern und dergleichen benötigt wird.In principle, during interruptions in operation, the time required to bring the units back to operating condition should be taken into account. This is especially true for the time required to heat sealing members, glue lines, glue nozzles, dry wheels and the like.

Den höchsten Automatisierungsgrad bietet die Auswahl der Programme nach Maßgabe des Betriebszustands der Verpackungsanlage 10. Aufgrund der Vernetzung der Organe der Verpackungsanlage 10 werden Informationen über den Betriebszustand der Verpackungsanlage 10 und der darin enthaltenen Aggregate über die Maschinensteuerungen 22 zur Steuereinheit 27 geleitet. Dabei können nicht nur Daten über den aktuellen Energieverbrauch der Organe, sondern auch Informationen über Störungen von einzelnen Organen an die Steuereinheit 27 übermittelt werden. Bei entsprechender Programmierung ist die Steuereinheit 27 nun in der Lage die für den jeweiligen Betriebszustand der Verpackungsanlage 10 passenden Programme automatisch auszuwählen.The highest degree of automation offers the selection of programs in accordance with the operating state of the packaging system 10. Due to the networking of the organs of the packaging system 10 information about the operating condition of the packaging system 10 and the units contained therein via the machine controls 22 to the control unit 27 passed. Not only data about the current energy consumption of the organs, but also information about disorders of individual organs to the control unit 27 can be transmitted. With appropriate programming, the control unit 27 is now able to automatically select the appropriate for the respective operating state of the packaging system 10 programs.

Beispielsweise ist es denkbar, dass im Bereich der Cellophaniermaschine 17 eine Störung vorliegt, die einen Stillstand dieses Aggregats und gegebenenfalls der Verpackungsanlage 10 erfordert. Die Meldung des Fehlers im Bereich der Cellophaniermaschine 17 wird von der Steuereinheit 27 ausgewertet und ein entsprechendes Programm gestartet, das beispielsweise das Vakuumgebläse 34 zur Versorgung der Cellophaniermaschine 17 mit Saugluft ausschaltet. Dies kann wie in Fig. 7 exemplarisch gezeigt auch erst nach einer gewissen Länge des Fehlers erfolgen, sodass kurzzeitige Unterbrechungen nicht zu einer Abschaltung führen.For example, it is conceivable that there is a fault in the area of the cellophaning machine 17, which requires a standstill of this unit and possibly of the packaging installation 10. The message of the error in the area of the cellophaning machine 17 is evaluated by the control unit 27 and a corresponding program started, for example, the vacuum fan 34 to supply the cellophaning machine 17 turns off with suction. This can be like in Fig. 7 shown as an example also take place only after a certain length of the fault, so that short-term interruptions do not lead to a shutdown.

Sofern durch Betriebsunterbrechungen bzw. Störungen im Bereich eines Organs andere Organe betroffen sind, können in der Steuereinheit 27 entsprechende Energiesparmodi auch für diese Organe hinterlegt sein.If other organs are affected by business interruptions or disruptions in the region of an organ, corresponding energy-saving modes can also be stored for these organs in the control unit 27.

Vorzugsweise ist die Steuereinheit 27 darüber hinaus als selbstlernendes System ausgebildet. Durch Überwachung der Betriebszustände der Organe der Verpackungsanlage 10 kann die Steuereinheit 27 Rückschlüsse darauf ziehen, wie viel Zeit zur Beseitigung bestimmter Störungen bzw. Betriebsunterbrechungen benötigt wird. Durch diese Messungen kann die Steuereinheit 27 dann die hinterlegten Programme anpassen und verbessern. Denkbar ist es auch, dass die Programme in Abhängigkeit vom zu verpackenden bzw. herzustellenden Produkt programmiert werden, beispielsweise in Abhängigkeit von der Zigarettenmarke bzw. des entsprechenden Packungstyps.Preferably, the control unit 27 is also designed as a self-learning system. By monitoring the operating conditions of the organs of the packaging installation 10, the control unit 27 can draw conclusions as to how much time is needed to eliminate certain disturbances or interruptions in operation. By these measurements, the control unit 27 can then adjust and improve the stored programs. It is also conceivable that the programs are programmed depending on the product to be packaged or manufactured, for example, depending on the cigarette brand or the corresponding type of pack.

Weiterhin ist es denkbar, dass eine Betriebsunterbrechung nicht oder nur bedingt dazu führen muss, dass die nicht von der Störung oder Unterbrechung betroffenen Organe ebenfalls bzw. in gleichem Maße in einen Energiesparmodus versetzt werden. Denkbar ist beispielsweise auch, dass zum Beispiel bei Störung des Hinge-Lid-Packers 14 in Fig. 1 die davor bzw. danach angeordneten Organe der Verpackungsmaschine 10, also in diesem Fall der Maker 11 und der Filteransetzer 12 sowie die Cellophaniermaschine 17 mit geringerer Produktionsgeschwindigkeit betrieben werden. Als weitere Alternative ist denkbar, dass die vorstehend genannten Organe zunächst bei normaler Betriebsgeschwindigkeit weiter produzieren, bis die Speicher 13 und 16 gefüllt bzw. geleert sind und dass erst danach durch entsprechende Programmierung die Geschwindigkeit verringert wird. All dies kann zentral durch die Steuereinheit 27 vorgegeben werden.Furthermore, it is conceivable that a business interruption does not have to lead, or only conditionally, to the fact that the organs not affected by the disturbance or interruption are likewise put into an energy-saving mode or to the same extent. It is also conceivable, for example, that, for example, if the hinge-lid packer 14 is disturbed Fig. 1 the before or after arranged organs of the packaging machine 10, so in this case the maker 11 and the filter applicator 12 and the cellophaning machine 17 are operated at a lower production speed. As a further alternative, it is conceivable that the above-mentioned organs continue to produce initially at normal operating speed until the reservoirs 13 and 16 are filled or emptied and that only then, by appropriate programming, is the speed reduced. All of this can be specified centrally by the control unit 27.

Denkbar ist weiterhin, dass die Steuereinheit 27 selbsttätig für neu eintretende Betriebszustände Programme generiert, um die Energieeffizienz zu erhöhen. Dies kann mit Hilfe der Messergebnisse, Fehlermeldungen und unter Zuhilfenahme statistischer Berechnungen erfolgen. Darüberhinaus ist es denkbar derartige Programmierungen auch noch in Abhängigkeit von anderen Faktoren vorzusehen, beispielsweise in Abhängigkeit von dem zu verpackenden Produkt, in Abhängigkeit der Leistungsfähigkeit der Bediener, in Abhängigkeit von Umwelteinflüssen wie beispielsweise Temperaturen, und dergleichen.It is also conceivable that the control unit 27 automatically generates programs for newly entering operating states in order to increase energy efficiency. This can be done with the help of the measurement results, error messages and with the help of statistical Calculations take place. Moreover, it is also conceivable to provide such programming in dependence on other factors, for example depending on the product to be packaged, as a function of the performance of the operators, as a function of environmental influences such as temperatures, and the like.

Die Steuereinheit 27 kann weiterhin dazu benutzt werden den Betrieb der Verpackungsanlage 10 im Hinblick auf den Energieverbrauch der Organe zu kontrollieren und anzuzeigen. Hierzu kann die Steuereinheit gemäß Fig. 4 einen Monitor 38 aufweisen zur Darstellung solcher Informationen. Denkbar ist, dass auf dem Monitor 38 Informationen zum Energieverbrauch der Organe oder gesamten Verpackungsanlage 10 dargestellt werden.The control unit 27 can further be used to control and display the operation of the packaging equipment 10 with respect to the power consumption of the organs. For this purpose, the control unit according to Fig. 4 have a monitor 38 for displaying such information. It is conceivable that information on the energy consumption of the organs or the entire packaging installation 10 is displayed on the monitor 38.

Fig. 4 zeigt in diesem Sinne einerseits eine Grafik 39 des Energieverbrauchs der Verpackungsanlage 10 in Abhängigkeit von der Zeit. Weiterhin zeigt Monitor 38 in einer weiteren Grafik 40 den spezifischen Energieverbrauch der Verpackungsanlage 10. Denkbar ist es auch diese Informationen bezogen auf einzelne Organe der Verpackungsanlage 10 darzustellen. Weiterhin verfügt die Steuereinheit 27 über mehrere Taster 41, sowie einen Regler 42 zur Auswahl der darzustellenden Informationen bzw. zur Auswahl der Programme und/oder Programmierung derselben. Fig. 4 shows in this sense, on the one hand, a graph 39 of the energy consumption of the packaging system 10 as a function of time. Furthermore, monitor 38 shows in a further graph 40 the specific energy consumption of the packaging installation 10. It is also conceivable to display this information in relation to individual organs of the packaging installation 10. Furthermore, the control unit 27 has a plurality of buttons 41, and a controller 42 for selecting the information to be displayed or for selecting the programs and / or programming the same.

Grundsätzlich ist es denkbar, dass nicht nur der aktuelle Energieverbrauch dargestellt wird, sondern dass chronologische oder statistische Auswertungen vorgenommen werden, wie beispielsweise Vergleiche mit dem Vortag, einer anderen Schicht oder einer anderen Verpackungsanlage 10.In principle, it is conceivable that not only the current energy consumption is displayed, but that chronological or statistical evaluations are made, such as comparisons with the previous day, another shift or another packaging installation 10.

Die Steuereinheit 27 erlaubt weiterhin die Auswertung des momentanen Energieverbrauchs der Organe, wie in Fig. 3 gezeigt.The control unit 27 further allows the evaluation of the instantaneous energy consumption of the organs, as in Fig. 3 shown.

Für jedes Organ ist dabei jeweils über einen Pfeil 43 der momentane Energieverbrauch angezeigt. Weiterhin ist durch einen Balken 44 ein Grenzwert angezeigt. Im vorliegenden Fall handelt es sich bei dem Grenzwert um einen Pegel, ab dem das entsprechende Organ einen überdurchschnittlich hohen Energieverbrauch aufweist. Entsprechend sollte die Verpackungsarilage 10 so betrieben werden, dass der Energieverbrauch jeweils unterhalb des jeweiligen Grenzwerts liegt. Es zeigt sich, dass beispielsweise die Laserbedruckung 36 und der Servomotor 33 oberhalb des Grenzwerts betrieben werden, was auf Störungen hindeuten kann. In beiden Fällen können zum Beispiel Verschmutzungen dazu führen, dass mehr Energie aufgewendet werden muss als eigentlich üblich. Ein solcher Anstieg des Energieverbrauchs kann umgekehrt darauf hindeuten, dass bestimmte Organe bzw. Aggregate verschmutzt sind und überholt, gereinigt oder gewartet werden müssen. Der Energieverbrauch muss natürlich nicht prozentual angegeben sein, sondern dies kann auch mit absoluten Angaben erfolgen.For each organ, the current energy consumption is indicated in each case via an arrow 43. Furthermore, a threshold 44 is indicated by a bar. In the present case, the limit value is a level above which the corresponding organ has an above-average energy consumption. Accordingly, the Verpackungsarilage 10 should be operated so that the energy consumption is below the respective limit. It can be seen that, for example, the laser print 36 and the servomotor 33 are operated above the limit value, which may indicate disturbances. In both cases, for example, soiling can lead to more energy being expended than usual. Conversely, such an increase in energy consumption may indicate that certain organs or aggregates are contaminated and need to be overhauled, cleaned or maintained. Of course, the energy consumption does not have to be stated as a percentage, but this can also be done with absolute information.

Weiterhin ist es denkbar, dass die Steuereinheit 27 die Verpackungsanlage 10 so steuert, dass möglichst geringe Energiekosten verursacht werden. Denkbar ist beispielsweise, dass die Steuereinheit 27 die Verpackungsanlage 10 so steuert, dass gewisse (insbesondere zyklische) Verpackungsprozesse dann stattfinden, wenn die Kosten für den Bezug der Energie besonders günstig sind. Denkbar wäre also beispielsweise eine Ausnutzung von Nachtstromtarifen oder dergleichen. Beispielsweise können auf diese Weise insbesondere zyklisch ablaufende Prozesse wie zum Beispiel die Tabakaufbereitung zu Zeiten ablaufen, in denen die Energie kostengünstig zur Verfügung steht. Sofern die Energie aus regenerativen Energiequellen stammt können die Prozesse auch nach Maßgabe zu erwartender Energieerträge aus den regenerativen Energiequellen ablaufen, beispielsweise unter Berücksichtigung bzw. nach Maßgabe von Wettervorhersagen.Furthermore, it is conceivable that the control unit 27 controls the packaging installation 10 in such a way that the lowest possible energy costs are caused. It is conceivable, for example, that the control unit 27 controls the packaging installation 10 such that certain (in particular cyclical) packaging processes take place when the costs for the procurement of the energy are particularly favorable. It would be conceivable, for example, an exploitation of night tariffs or the like. For example, in this way, in particular cyclical processes such as tobacco processing can take place at times when the energy is available at low cost. If the energy comes from regenerative energy sources, the processes can also take place in accordance with expected energy yields from the regenerative energy sources, for example, taking into account or in accordance with weather forecasts.

Eine weitere Besonderheit kann darin bestehen, dass die Programme vorsehen die Organe rechtzeitig vor Beendigung der Betriebsunterbrechung wieder in den Betriebsmodus zu versetzen. Denkbar ist beispielsweise ein rechtzeitiges Aufheizen von Heizorganen, wie z.B. die Schrumpfheizung 28, sodass zum Ende der Betriebsunterbrechung der Betriebsmodus vorliegt. Dies kann bei zeitgesteuerten Programmen fest programmiert werden oder die Steuereinheit 27 lernt anhand von bereits eingetretenen Ereignissen, um die Programme entsprechend anzupassen.Another peculiarity may be that the programs provide for the institutions to return to operational mode in good time before the end of the business interruption. For example, timely heating of heating elements, such as e.g. the heat shrink 28, so that at the end of the interruption of the operating mode is present. This can be hard-coded in timed programs, or the control unit 27 learns from events that have already occurred to adjust the programs accordingly.

Eine weitere Besonderheit ist in Fig. 5, 6 und 8 gezeigt. Die Darstellungen befassen sich mit Maßnahmen zur Unterstützung eines Energiesparmodus. Es ist vorgesehen, dass Maßnahmen getroffen werden, um die Fortsetzung des Verpackungsprozesses nach einer Betriebsunterbrechung bzw. der Aktivierung eines Energiesparmodus gewährleisten zu können.Another special feature is in Fig. 5, 6 and 8th shown. The illustrations deal with measures to support a power saving mode. It is envisaged that measures will be taken to ensure the continuation of the packaging process after a business interruption or the activation of a power-saving mode.

Exemplarisch wird eine solche Maßnahme am Beispiel der Cellophaniermaschine 17 erläutert. Es ist üblich, dass das Verpackungsmaterial 45 in diesem Bereich über Umlenkrollen 46 in den Bereich eines Saugförderers 47 geführt wird. Mit Hilfe des Saugförderers 47 wird ein Zuschnitt des Verpackungsmaterials 45, welches mittels einer Trenneinrichtung 48 aus dem Verpackungsmaterial 45 vereinzelt wird, im Transportweg eines zu verpackenden Produkts 49 bereitgehalten. Das Produkt 49 wird durch den in einer vertikalen Ebene auf dem Saugförderer 47 bereitgehaltenen Zuschnitt hindurchgefördert und in eine Tasche 50 eines Siegelrevolvers 51 eingeschoben. Der Saugförderer 47 wird dazu über ein Vakuumgebläse 34 mit einem Unterdruck versorgt.By way of example, such a measure is explained using the example of the cellophaning machine 17. It is common that the packaging material 45 is guided in this area via deflection rollers 46 in the region of a suction conveyor 47. With the help of the suction conveyor 47 is a blank of the packaging material 45, which is separated by means of a separator 48 from the packaging material 45, held in the transport path of a product to be packaged 49. The product 49 is conveyed through the cut prepared in a vertical plane on the suction conveyor 47 and inserted into a pocket 50 of a sealing turret 51. The suction conveyor 47 is supplied via a vacuum blower 34 with a negative pressure.

Im Falle der Abschaltung des Vakuumgebläses 34 bei einer längeren Betriebsunterbrechung (Fig. 7) würde es unweigerlich dazu kommen, dass die bereits vereinzelten Zuschnitte vom Umfang des Saugförderers 47 herabfallen. Infolge dessen würde beim Anfahren der Vorrichtung nach Ende der Betriebsunterbrechung zwangsläufig ein Produkt 49 unverpackt in den Siegelrevolver 51 eingeschoben werden.In the case of shutdown of the vacuum fan 34 during a prolonged stoppage ( Fig. 7 ) it would inevitably happen that the already isolated blanks fall off the circumference of the suction conveyor 47. As a result, would inevitably be a product 49 unpacked inserted into the sealing turret 51 when starting the device after the end of the business interruption.

Zur Lösung dieses Problems ist vorgesehen, dass bei Abschaltung des Vakuumgebläses 34 automatisch eine Halteeinrichtung 52 aktiviert wird zur Sicherung der Lage des Verpackungsmaterials 45 bzw. eines einzelnen Zuschnitts am Saugförderer 47.To solve this problem, it is provided that when the vacuum blower 34 is switched off, a holding device 52 is automatically activated to secure the position of the packaging material 45 or a single blank on the suction conveyor 47.

Die Halteeinrichtung 52 ist derart konstruiert, dass bei Abschalten des Vakuumgebläses 34 automatisch eine mechanische Lagesicherung des Verpackungsmaterials 45 erfolgt.The holding device 52 is constructed in such a way that when the vacuum fan 34 is switched off, a mechanical securing of the position of the packaging material 45 takes place automatically.

Im vorliegenden Fall ist hierzu eine Haltebacke 53 vorgesehen, der mittels einer Feder 54 gegen den Saugförderer 47 gedrückt wird und dabei das Verpackungsmaterial 45 gegen den Saugförderer 47 drückt. Die Haltebacke 53 ist an einem Schaft 55 angeordnet, der eine entsprechende Öffnung eines Gehäuses 56 durchdringt. Innerhalb des Gehäuses 56 ist am Schaft 55 eine Saugplatte 57 angeordnet, an der die Feder 54 anliegt und die Haltebacke 53 unter Abstützung an einer Wandung des Gehäuses 56 gegen den Saugförderer 47 drückt. Weiterhin hat das Gehäuse 56 einen Anschluss 58 zur Verbindung mit dem Vakuumgebläse 34. Im vorliegenden Fall verfügt der Saugförderer 47 über zwei Saugriemen 59, wobei jedem Saugriemen 59 eine Halteeinrichtung 52 zugeordnet ist.In the present case, a holding jaw 53 is provided for this purpose, which is pressed by means of a spring 54 against the suction conveyor 47 and thereby pushes the packaging material 45 against the suction conveyor 47. The holding jaw 53 is arranged on a shaft 55, which penetrates a corresponding opening of a housing 56. Within the housing 56, a suction plate 57 is arranged on the shaft 55, against which the spring 54 and the holding jaw 53 presses under support on a wall of the housing 56 against the suction conveyor 47. Furthermore, the housing 56 has a port 58 for connection to the vacuum blower 34. In the present case, the suction conveyor 47 has two suction belts 59, each suction belt 59 is associated with a holding device 52.

Die Funktionsweise der Halteeinrichtung 52 ergibt sich aus der Darstellung gemäß Fig. 8. Die untere Darstellung in Fig. 8 zeigt die Halteeinrichtung 52 im Betriebszustand. Über den Anschluss 48 wird ein Unterdruck im Gehäuse 56 erzeugt, der dazu führt, dass die Saugplatte 57 unter Vorspannung der Feder 54 angesaugt wird. Dies führt wiederum dazu, dass der Bremsklotz 53 der Halteeinrichtung 52 vom Saugförderer 47 beabstandet wird. Bei Abschaltung des Vakuumgebläses 34 aufgrund entsprechender Programmierung der Steuereinheit 47 wird - wie der obere Teil der Fig. 8 zeigt - der Bremsklotz 53 durch die Feder 54 gegen den Saugförderer 47 gedrückt.The mode of operation of the holding device 52 results from the illustration according to FIG Fig. 8 , The lower illustration in Fig. 8 shows the holding device 52 in the operating state. Via the port 48, a negative pressure in the housing 56 is generated, which causes the suction plate 57 is sucked under bias of the spring 54. This in turn means that the brake pad 53 of the holding device 52 is spaced from the suction conveyor 47. When switching off the vacuum fan 34 due to appropriate programming of the control unit 47 is - like the upper part of the Fig. 8 shows - the brake pad 53 pressed by the spring 54 against the suction conveyor 47.

Mit anderen Worten sieht dieser Aspekt der Erfindung vor, dass den im Energiesparmodus abgeschalteten oder heruntergeregelten Organen Sicherungsmittel zugeordnet sind, um eine Fortsetzung des Verpackungsprozesses nach Reaktivierung des Betriebszustands zu gewährleisten.In other words, this aspect of the invention provides that securing means are switched off or down-regulated in the energy-saving mode in order to ensure continuation of the packaging process after reactivation of the operating state.

In diesem Sinne ist es grundsätzlich denkbar, dass Verpackungsmaterialien und/oder Produkte bei Einleitung von Energiesparmaßnahmen durch mechanische Haltemittel als Sicherungsmittel derart fixiert werden, dass nach Beendigung des Energiesparmodus die Produktion fortgesetzt werden kann, ohne dass ein Eingriff in den Produktionsablauf erforderlich ist, insbesondere durch einen Bediener. In Frage kommt eine solche Lösung beispielsweise beim Transport oder Fixieren von Produkten mittels Unterdruck, Druckluft oder Fliehkraft.In this sense, it is conceivable in principle that packaging materials and / or products are fixed at initiation of energy savings by mechanical holding means as securing means such that after completion of the energy saving mode production can be continued without intervention in the production process is required, in particular by an operator. In question comes such a solution, for example, when transporting or fixing products by means of negative pressure, compressed air or centrifugal force.

Daneben ist es beispielsweise möglich elektromagnetisch arbeitende Halteeinrichtungen als Sicherungsmittel bei Einleitung von Energiemaßnahmen durch mechanische Mittel zu ersetzen. Denkbar ist in diesem Sinne elektronmagnetische Halteeinrichtungen in Elektromotoren (beispielsweise für Servoantriebe) durch mechanische (Federdruck-) Bremsen zu ersetzen.In addition, it is possible, for example, to replace electromagnetically operating holding devices as securing means when introducing energy measures by mechanical means. It is conceivable in this sense to replace electronic-magnetic holding devices in electric motors (for example for servo drives) by mechanical (spring-loaded) brakes.

Eine andere Lösung sieht vor, dass Handhabungsgeräte bei Einleitung von Energiesparmaßnahmen in Parkpositionen mechanisch gehalten werden. Denkbar ist beispielsweise die Ablage eines Roboterarms in einer Parkstellung, in der die Stromzufuhr zum Roboterarm abgestellt werden kann.
