The invention is characterized in that to improve the energy efficiency of the packaging installation (10), organs are at least partially switched by means of at least one control unit (27) at least temporarily into an energy-saving mode in which the corresponding organs require less energy than in an operating mode.

Description

The invention relates to a system and / or a method for operating a packaging installation for products, in particular tobacco articles, wherein within a packaging installation several organs of the packaging installation, in particular packaging machines or units thereof follow one another within a packaging process, according to the preamble of claim 1.

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.

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.

To solve this problem, an inventive system has the features of claim 1. It is therefore envisaged that, in order to improve the energy efficiency of the packaging system, the organ is at least partially switched by means of at least one control unit at least temporarily into an energy-saving mode in which the corresponding organs require less energy than in an operating mode.

Energy efficiency is generally understood as the efficiency of the use of energy, ie the ratio of benefits to energy expenditure. In terms of a packaging system, energy efficiency means specific energy consumption, ie the energy required to package a product.

An advantage of the system according to the invention can be that the energy consumption of the organs is reduced by appropriate control and / or regulation thereof. This improvement is independent of the plant efficiency, ie the production rate of the plant. The energy efficiency of the system should not be confused with the choice of organs that consume (constant) little energy.

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.

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.

Provided that the institutions have different operating modes. exist - for example, for different products - it may be conceivable that the operating mode for a product corresponds to a power saving mode for another product.

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.

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.

For example, a program for "normal operation" would be conceivable, in which all organs are operated in operating mode. Optionally, several programs for the "normal operation" exist, for. B. 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.

In particular, it is conceivable to operate low-temperature heaters in accordance with the product to be packaged.

Furthermore, it is conceivable that the organs are controlled in accordance with the production speed or regulated. It would be conceivable that at low production speed of the packaging system, the heaters are operated at a lower temperature and vice versa.

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 conceivable z. For example, certain equipment may be operated individually according to operators at higher or lower production speeds to minimize specific energy consumption.

In practice, a great importance should also be assigned to programs that are used in the event of business interruptions, such as As breaks, malfunctions, during maintenance, after hours, on weekends, in plant 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.

• – 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.

In the automatic selection is on the one hand a timed 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.

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.

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.

• – 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 plant ( 10 ) and / or their organs,
• - time,
• - product,
• - Operator or operating team.

The acquired data can then be stored, for example, in the control unit ( 27 ), the machine control or a line computer.

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.

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.

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.

As an example, one could imagine that for the first time an aggregate of a folding turret fails in a packaging system for cigarettes, whereby no programming exists for this error. 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.

It goes without saying that this procedure can be used not only in the case of faults or errors, but also in the case of planned interventions in the operating procedure, such as, for example, For example, when changing brands, product changes, maintenance, etc.

Other special features concern the "prediction" of the expected duration of business interruptions. Based on the stored data, the expected duration of the interruption is determined by means of statistical calculations or probability calculations. In this case, it is also preferably taken into account which organs in which combination are affected by the business interruption, because this too can influence the duration of the business interruption.

Other special features concern constructive solutions in the displacement of organs in a power-saving mode.

A preferred embodiment of the invention will be described below with reference to the drawing. In this show:

The invention will be described below with reference to a packaging system 10 for tobacco products exemplified. The packaging system 10 includes in the illustrated embodiment an entire packaging line from the production of cigarettes to the packaging of bundles of packages.

It is understood that it is a packaging plant 10 does not necessarily have to act around an entire packaging line. A packaging plant 10 may also include only a single packaging machine or a single packaging unit.

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.

The packaging system 10 according to 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, linguistic simplification is always followed by organs of the packaging plant 10 be the talk. This term includes all controllable or controllable components of the packaging plant 10 , so ultimately the packaging machines, their aggregates, sub-aggregates, etc.

• – Filteransetzer 12,

• – Hinge-Lid-Packer 14,
• – Zuschnittmagazin 15,
• – Packungsspeicher 16,
• – Cellophaniermaschine 17,
• – Stangenpacker 18,

In the in 1 shown embodiment of a packaging system 10 the following organs follow each other within the packaging line or the packaging process:

• - Maker 11 .
• - Filter piecing 12 .
• - cigarette storage 13 .
• - Hinge-lid packer 14 .
• - Blank magazine 15 .
• - Pack storage 16 .
• - Cellophaning machine 17 .
• - bar packer 18 .
• - Carton packer 18 ,

On the side next to the packaging line is a bobbin store 20 arranged with packaging materials for the individual organs of the packaging plant 10 , By means of a Bobinenversorgung 21 The packaging materials can be supplied to the individual organs.

The organs of the packaging plant 10 are each machine controls 22 assigned, for controlling the respective machine or the respective organ. These are via control lines 23 with a host 24 connected. The main computer 24 in turn, can via lines 25 . 26 connected to the Internet and / or the intranet.

At a production site, several such packaging plants can 10 operated, if necessary, over the lines 25 to the intranet can be controlled together in the network. It is also conceivable to couple several packaging systems 10 via the Intranet and / or the Internet, to order from one or more central packaging facilities 10 at one or more Control, regulate, control or evaluate locations.

To increase the energy efficiency of the packaging plant 10 or their organs is a control unit 27 intended. The control unit 27 can be realized as a separate device and with the packaging system 10 over the wires 25 . 26 be connected or in the main computer 24 be arranged. In the control unit 27 are preferably different programs for operating the packaging system 10 saved. Depending on the intended use, the programs will see different configurations for the packaging system's organs 10 in front.

An example of a first program in the event of a business interruption is in 7 shown. In the left column of the diagram are individual organs of the packaging plant 10 In addition, each configuration is dependent on the length of the business interruption. In the present case, it is provided that the temperature of a shrinkage heating 28 is lowered to a temperature of 50 ° C during short interruptions, with a longer interruption of operation, the temperature is lowered to 30 ° C and finally at long interruption is the heat shrink 28 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.

Corresponding configurations are for a hot glue reservoir 29 , a monitor 30 , a machine lighting 31 , an emergency stop switch 32 , a servomotor 33 , a vacuum blower 34 , a camera control 35 and a laser print 36 intended.

In addition, in a program, of course, the configuration for the "normal" operation of the organs be deposited. The next to the icons in 7 executed configurations of the organs then stand for the different energy-saving modes of the same.

The control unit 27 In the present case, it is set up to set up, display and select the programs. As already mentioned, this is possible because the organs with the respective machine controls 22 and this with the control unit 27 are connected. 2 shows as other organs of the packaging plant 10 another switch cabinet 37 and the cellophaning machine 17 ,

• – manuell
• – automatisch und zeitgesteuert
• – automatisch nach Maßgabe des Betriebszustands.

The selection of programs can be as in 2 indicated in three different ways, namely

• - manually
• - automatically and timed
• - automatically according to the operating condition.

These three methods are in 2 by corresponding symbols in the control unit 27 indicated.

A simple case is the manual selection of programs. By an operator can at a control unit 27 the individual programs are selected. This can, for example, depending on the operating state of the packaging system 10 depending on the product to be manufactured or depending on other boundary conditions.

If a fault occurs which leads to an interruption of service, the operator can call the control unit 27 select a program that will then switch one or more or all organs to a power-saving mode. This energy saving mode can be constant until the program finishes or as in 7 be shown time-dependent.

Timed programming of the control unit 27 On the other hand, it enables automatic consideration of given interruptions in operation, such as in the case of breaks, shift changes, at closing time, on weekends, during company holidays or the like. Also for scheduled maintenance work such time-controlled programs can be used.

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.

The highest level of automation is provided by the selection of programs according to the operating status of the packaging system 10 , Due to the networking of the organs of the packaging plant 10 Information about the operating status of the packaging system 10 and the aggregates contained therein via the machine controls 22 to the control unit 27 directed. It can not only provide data on the current energy consumption of the organs, but also information about disturbances of individual organs to the control unit 27 be transmitted. With appropriate programming, the control unit 27 now capable of the respective operating condition of the packaging plant 10 automatically select suitable programs.

For example, it is conceivable that in the field of cellophaning machine 17 there is a fault, the stoppage of this unit and, where appropriate, the packaging system 10 requires. The message of the error in the area of the cellophaning machine 17 is from the control unit 27 evaluated and started a corresponding program, for example, the vacuum fan 34 for supplying the cellophaning machine 17 switches off with suction air. This can be like in 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.

If other organs are affected by business interruptions or disruptions in the area of one organ, the control unit can 27 appropriate energy saving modes also be deposited for these organs.

Preferably, the control unit 27 in addition, designed as a self-learning system. By monitoring the operating conditions of the organs of the packaging plant 10 can the control unit 27 Draw conclusions as to how much time is required for the elimination of certain malfunctions or business interruptions. Through these measurements, the control unit 27 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.

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 in case of disturbance of the Hinge-Lid-Packers 14 in 1 the before or after arranged organs of the packaging machine 10 So in this case the maker 11 and the filter piecing 12 as well as the cellophaning machine 17 be operated at a lower production speed. As a further alternative, it is conceivable that the above-mentioned organs continue to produce at normal operating speed until the memories 13 and 16 are filled or emptied and that only then by appropriate programming the speed is reduced. All of this can be done centrally by the control unit 27 be specified.

It is also conceivable that the control unit 27 automatically generates programs for new operating states to increase energy efficiency. This can be done with the help of the measurement results, error messages and with the aid of statistical calculations. 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.

The control unit 27 can also be used to operate the packaging system 10 to control and display with regard to the energy consumption of the organs. For this purpose, the control unit according to 4 a monitor 38 have to display such information. It is conceivable that on the monitor 38 Information about the energy consumption of the organs or the entire packaging plant 10 being represented.

4 shows in this sense, on the one hand, a graphic 39 the energy consumption of the packaging plant 10 depending on the time. Furthermore, monitor shows 38 in another graphic 40 the specific energy consumption of the packaging plant 10 , It is also conceivable this information related to individual organs of the packaging plant 10 display. Furthermore, the control unit has 27 over several buttons 41 , as well as a regulator 42 to select the information to be presented or to select the programs and / or programming them.

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 layer or another packaging plant 10 ,

The control unit 27 also allows the evaluation of the current energy consumption of the organs, as in 3 shown.

Each organ has an arrow 43 the current energy consumption is displayed. Furthermore, by a bar 44 a limit is displayed. In the present case, the limit value is a level above which the corresponding organ has an above-average energy consumption. Accordingly, the packaging system should 10 be operated so that the energy consumption is below the respective limit. It turns out that, for example, the laser printing 36 and the servomotor 33 above the limit, which may indicate disturbances. In both For example, pollution can lead to more energy being consumed 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.

Furthermore, it is conceivable that the control unit 27 the packaging plant 10 so controls that the lowest possible energy costs are caused. It is conceivable, for example, that the control unit 27 the packaging plant 10 Thus, certain (especially cyclical) packaging processes take place when the costs of purchasing 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.

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. It is conceivable, for example, a timely heating of heating elements, such. B. the shrinkage heater 28 so that the operating mode is at the end of the business interruption. This can be hard-coded for timed programs or the control unit 27 learns from events that have already occurred to adjust the programs accordingly.

Another special feature is in 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.

By way of example, such a measure is exemplified by the cellophaning machine 17 explained. It is common for the packaging material 45 in this area via pulleys 46 in the area of a suction conveyor 47 to be led. With the help of the suction conveyor 47 becomes a blank of the packaging material 45 , which by means of a separator 48 from the packaging material 45 is singulated, in the transport path of a product to be packaged 49 kept ready. The product 49 gets through the in a vertical plane on the suction conveyor 47 prepared blank conveyed and in a bag 50 a seal revolver 51 inserted. The suction conveyor 47 is done via a vacuum blower 34 supplied with a negative pressure.

In case of shutdown of the vacuum blower 34 during a longer business interruption ( 7 ) it would inevitably come to that the already isolated blanks from the scope of the suction conveyor 47 fall. As a result, when starting the device after the end of the business interruption inevitably a product 49 unpacked in the sealing turret 51 be inserted.

To solve this problem is provided that when switching off the vacuum fan 34 automatically a holding device 52 is activated to secure the position of the packaging material 45 or a single blank on the suction conveyor 47 ,

The holding device 52 is designed so that when switching off the vacuum blower 34 automatically a mechanical position assurance of the packaging material 45 he follows.

in the present case, this is a holding jaw 53 provided by means of a spring 54 against the suction conveyor 47 is pressed while the packaging material 45 against the suction conveyor 47 suppressed. The holding jaw 53 is on a shaft 55 arranged, which has a corresponding opening of a housing 56 penetrates. Inside the case 56 is on the shaft 55 a suction plate 57 arranged at the the spring 54 abuts and the holding jaw 53 under support on a wall of the housing 56 against the suction conveyor 47 suppressed. Furthermore, the housing has 56 a connection 58 for connection to the vacuum blower 34 , In the present case, the suction conveyor has 47 over two suction belts 59 , with each suction belt 59 a holding device 52 assigned.

The operation of the holding device 52 follows from the illustration according to 8th , The lower illustration in 8th shows the holding device 52 in the operating state. About the connection 48 There is a negative pressure in the housing 56 generated, which causes the suction plate 57 under bias of the spring 54 is sucked. This in turn causes the brake pad 53 the holding device 52 from the suction conveyor 47 is spaced. When switching off the vacuum fan 34 due to appropriate programming of the control unit 47 will - like the upper part of the 8th shows - the brake pad 53 through the spring 54 against the suction conveyor 47 pressed.

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 this sense, it is conceivable in principle that packaging materials and / or products are fixed at initiation of energy saving measures 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.

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.

Another solution provides that handling devices are mechanically held when initiating energy-saving measures in parking positions. It is conceivable, for example, the storage of a robot arm in a parking position in which the power supply to the robot arm can be turned off.
