Description

[0001] The invention relates to a method for operating a machine, in particular a printing press, which processes and / or handles a substrate, especially a web- or arc-shaped one, with a system supporting energy efficiency, and to a machine, in particular a printing press, with such a system according to the preamble of claim 1 or 10.

[0002] Machines that process or handle substrates, such as printing presses, especially sheet-fed presses, often consume a significant amount of energy during production, primarily electrical energy. On the one hand, this results in very high costs for operators, such as printing companies, which must be reduced, particularly in times of rising energy prices. Peak loads, which exceed average expected consumption, are often especially expensive. On the other hand, the efficient use of energy is also of great interest for environmental protection reasons.

[0003] For example, DE 10 2016 209 118 A1 discloses an energy management system for a printing plant, designed to prevent energy consumption exceeding threshold values ​​for all machines. This system includes, for instance, indicator lights whose switching states change between green, yellow, and red depending on whether certain threshold values ​​for the total power consumption across all consumers are exceeded. In the case of red, the indicator prompts the respective operator to take energy-saving action. In one embodiment, the system simplifies the process for personnel by allowing different consumers, e.g.,Printing presses, dryers, or other equipment are monitored, and the system itself highlights one of several defined states as a suggestion on a screen to determine the production speed. If accepted by staff, this suggestion would eliminate the impermissible exceedance. If no action is taken and an even higher limit is exceeded, the system can, as a last resort, automatically select and implement a suitable measure.

[0004] The invention is based on the objective of creating a method for operating a web- or arc-shaped substrate processing machine, in particular a printing press, with a system supporting energy efficiency, as well as a machine with such a system.

[0005] The problem is solved according to the invention by the features of claim 1 or 10.

[0006] In this process, when operating a machine – in particular a web- or arc-shaped – that processes and / or handles a substrate, especially a printing press, with a plurality of electrical power consumers, data sets describing past production situations are stored in a data storage system of a system supporting the energy-efficient operation of the machine, in short an energy efficiency system. These data sets include at least data on product-specific properties, production speed, operating parameters relating to the consumers, and total power consumed by the consumers considered. The machine is operated in a production situation with a current set of operating parameters relating to the consumers and a production speed to manufacture a product with specific product-specific properties.At a certain point during operation in this production situation, one or more measuring devices determine the total power consumption of the majority of the considered consumers. At least the product-specific characteristics of the current production situation and the data relating to the total power consumption are transmitted to the energy efficiency system, and the data already stored there is checked to see if a data record for a production situation with comparable product-specific characteristics but a lower total electrical power consumption already exists in the data storage. If so, the operating parameters contained in a found data record are adopted for the further operation of control devices of a machine control system or at least suggested to the operating personnel for adoption.

[0007] In a machine, particularly a printing press, which includes such an energy efficiency system and is particularly suitable for the above procedure, the energy efficiency system is in signal communication with the control means controlling the machine and with one or more measuring devices that determine the total power consumption of consumers to be taken into account. The energy efficiency system includes data processing means which are configured to check data transmitted by the control means, at least regarding the product-specific characteristics of a current production situation and the current total power consumption, to see whether a data record for a production situation with comparable product-specific characteristics and a lower total electrical power consumption already exists in the data storage.and, if successful, to transfer the operating parameters contained in a found data set to the control system for further operation or to suggest them to the operating personnel for adoption at a display device.

[0008] The advantages achievable with the invention consist in particular of the fact that unnecessarily high energy consumption and / or undesirable exceedances of threshold or limit values ​​for the consumption of electrical power can be avoided.

[0009] In particular, the system continuously improves through the repeated storage of data on respective production situations – at least over a period of time – leading to increasingly efficient operating methods.

[0010] By examining and analyzing the available data for more energy-efficient production situations from the past, the most energy-efficient operation of the machine can be achieved, becoming less dependent on the individual experience of individual operators.

[0011] Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

[0012] They show: Fig. 1 an example of a machine designed as a printing press with multiple printing units and a system supporting the energy-efficient operation of the machine, hereinafter also referred to as the energy efficiency system; Fig. 2 a diagram for a first process sequence “A” when operating the machine using the energy efficiency system; Fig. 3 a diagram for a second procedure sequence “B” when operating the machine using the energy efficiency system; Fig. 4. An exemplary table showing data stored in the energy efficiency system relating to past production situations; Fig. 5 An example illustrating the use of the energy efficiency system and performance measurement for the operation of the machine.

[0013] A machine that processes and / or handles substrate S, e.g., a printing press, especially a sheet-fed printing press, comprises, for example, a substrate feeder 01, e.g., a feeder 01 for providing, e.g., sheet-shaped substrate S, one or more processing units 02; 03, and a product delivery unit 04, e.g., a stack delivery unit 04. In the case of web-shaped substrate S, the substrate feeder 01 can be a roll unwinder, and the product delivery unit a roll rewinder or—after, e.g., cutting and possibly further processing—a delivery unit for individual products. The substrate S can consist, for example, of paper, cardboard, corrugated board, plastic, metal, or a combination thereof.

[0014] As processing units 02, 03, one or more printing units 02 and / or one or more coating units 03 and / or one or more mechanical processing units, e.g., die-cutting or embossing units, can be arranged in the substrate path. Components 06; 07; 11 of the machine serving substrate conveying and processing are driven by one or more electrically operated drives 08; 09, in particular drive motors 08; 09.

[0015] In particular, the substrate S is transported by one or more motor-driven substrate guide elements 06; 07, preferably for arc-shaped substrate S, hereinafter referred to as substrate arc S, e.g., motor-driven cylinders 06; 07, such as cylinders 06 transporting the substrate arc S through a respective processing gap and acting as counter-pressure cylinders 06, and / or further transfer cylinders 07 serving only for further transport. In the case of a web-shaped substrate S, these can be cylinders involved in the processing gap and / or traction rollers. The cylinders 06; 07 that accomplish the transport on the substrate path through the processing units 02; 03 can be driven individually, in groups, or together by a drive motor 08, e.g., a so-called main drive 08. In addition, drive connections to the main drive 08 or, alternatively, further drive motors can be provided to drive the substrate feed 01 and / or the product discharge 03.

[0016] In addition to, for example, the counter-pressure cylinders 06 used for transport, further components 11 of the machining units 02; 03 include, for example, positively driven cylinders 11. Depending on the type of machining unit 02; 03, positively driven cylinders 11 can be provided as form cylinders 11 with appropriate features, e.g., a cylinder 11 carrying a printing or coating form, or possibly a die-cutting or embossing die, and can be driven either by the main drive 08 or indirectly or directly by a drive motor 09 that is mechanically independent of the main drive 08. These form cylinders 11 can be driven individually or as a group together with other functional parts, e.g., cylinders or rollers, of the respective machining unit 02; 03.

[0017] In addition to the electrical consumers 08; 09 formed by the drive motor(s) 08; 09, the machine may be assigned further electrical consumers 12; 13; 14, such as a compressor 12 for the supply of compressed air and / or other pressure fluids, one or more electrically operated dryers 13; 14, lighting equipment, air conditioning, temperature control of process fluids, e.g. paint, varnish or temperature control fluid, or other peripheral devices or equipment not shown in figures.

[0018] An important and increasingly important objective for such machines is to ensure the most energy-efficient operation possible, preferably without or with minimal limitations in quality and productivity. To meet or at least come closer to achieving this objective, the machine is equipped with a system 16 – primarily database-based – to support energy-efficient operation, hereinafter also referred to as "Energy Efficiency System 16".

[0019] In order to have knowledge of the total energy consumption P - preferably at any time or at any desired time GTo advantageously provide information about specific partial consumption, a measuring device 17 for determining the instantaneous electrical power consumption is provided at least in one of the main lines supplying the machine with electrical energy. This device can be designed, for example, as a power meter or – if the mains voltage is known and stable – as an ammeter and is hereinafter also referred to, for example, as power measuring device 17. The total power P can be determined by this inlet-side measuring device 17. G(e.g., specified in kilowatts or kW) are determined and transmitted indirectly or directly to the aforementioned system 16 via appropriate signal connections, e.g., via a control or monitoring station 23 of the printing press. Alternatively or additionally, individual measuring devices 18, or power measuring devices 18, which determine the instantaneous consumption of electrical power, can be provided for individual consumers 08, 09, 12, 13, 14 or groups of consumers, and their consumption values ​​can be transmitted to the aforementioned system 16. If only such measuring devices 18, which determine only partial consumption, are provided, the total power P G to form by their sum.

[0020] The energy efficiency system 16 comprises at least one data storage device 19, e.g., in the form of a database 19, in which data records D containing production-relevant parameters for a production process can be stored and retrieved, as well as data processing means 21, via which the data storage device 19 is to be supplied with data records D and via which queries to the database for retrieving and retrieving specific data records are or can be directed—e.g., queries formulated there using appropriately configured software routines and / or initiated externally by operating personnel. Furthermore, the system 16 comprises a respective signal connection to the common or respective power measuring device 17; 18, via which the current consumption data are transmitted, as well as a signal connection to the control means 22 controlling the machine, e.g.,a machine control system and / or a control or monitoring station 23 encompassing this system, via which product- and operation-relevant data DP; DB as well as a quantity representing the production speed V are or can be transmitted to the system. The energy efficiency system 16 is preferably in signal connection to an operator interface 24, which has, for example, buttons for input or at least for confirmation and / or selection of a suggestion, as well as a display device 26, e.g., a display 26 or monitor 26, on which measured values ​​for electrical power supplied by the energy efficiency system 16 and / or suggestions for energy-reduced operation can be displayed. The operator interface 24 and the display device 26 can be specifically assigned to the energy efficiency system 16 or can be connected to the data processing means 21 of the energy efficiency system 16 via signal technology as part of the control or monitoring station 24.

[0021] The data sets D belonging to a respective production situation, or production for short, include, as production-relevant variables, e.g., data on product-specific properties D. P , i.e., data relating to the properties of the product to be manufactured D P as well as data on operating parameters relating to this production situation D B of the machine or machine components. As product-specific properties D P The data set D includes, for example, at least one property characterizing the substrate S underlying the production, e.g., its basis weight, and / or at least one property characterizing the pressure, e.g., the area coverage. Data relating to the operating parameters D PParticularly relevant are energy-related process parameters, e.g., a measure of the operating speed or load setting, e.g., for a dryer, the specification of full or partial load in percent [%] (see example table from Fig. 4) Furthermore, a data set D relating to a specific production situation includes information representing the production speed V, which is given, for example, in manufactured products per unit of time (as is common in the field of web processing machines) or in substrate sheets S per hour (e.g. [B / h]) (as is common in the field of sheet processing machines).

[0022] The data on the product-specific properties D P and to the operating parameters D BWithin a specific production situation, the data points D are fixedly related to each other and thus represent a specific constellation, which, for example, can be assigned an identifier in its entirety, such as a database ID. In particular, the production speed V and the total output P determined or recorded in this production situation are also relevant. G .

[0023] In an energy efficiency system 16, which supports the energy-efficient operation of the machine, past production situations are gradually stored in the data storage 19. P , D B , V descriptive data records D stored (see e.g. the table in as an example) Fig. 4) The production situations D P , D B , V are thereby at least based on product-specific properties D P, based on a production speed V and based on operating parameters D relating to consumers 08; 09; 12; 13; 14 B and information on the total power consumed by the consumers considered (08; 09; 12; 13; 14) P G described. The latter can also consist of a specification of several partial services which together constitute the total service P. G represent. The first such data sets D can be generated and stored, for example, during a test or commissioning phase, or over time during production in different production situations.

[0024] When operating a machine that processes and / or handles a web- or arc-shaped substrate S in a specific production situation D, different from an initial operation P , D B , V with a current set of operating parameters D concerning the consumers under consideration 08; 09; 12; 13; 14 Band a production rate V for manufacturing a product with specific product-specific properties D P (see e.g. step A1 in Fig. 2 or B1 in Fig. 3) at a time during operation, the total power P consumed by the consumers under consideration 08; 09; 12; 13; 14 is measured by one or more of the aforementioned measuring devices 17; 19. G determined, for example by the at least one measuring device 17; 19 recorded (see e.g. step A2 in Fig. 2) This occurs particularly during stable operation and the production of saleable products, in the case of the sheet-fed printing press, for example, so-called "good sheets", i.e., production with sufficiently good quality.

[0025] From the control means 22 controlling the machine, at least the current product-specific properties D are determined. Pand from the at least one measuring device 17; 19 - directly or indirectly, e.g. via the control or monitoring station - the total power P consumed by the consumers 08; 09; 12; 13; 14 taken up G The relevant data are transmitted to the energy efficiency system 16 and – e.g., using the appropriately configured data processing equipment 21 – the data records D already stored in the data storage 19 are checked to see if a data record D for a production situation D already exists there. P , D B* , V with comparable product-specific properties D P , i.e., with the same or, up to a defined maximum deviation, e.g., of a maximum of 10%, similar area coverage and / or the same basis weight, but with a lower total electrical power P G is (see e.g. step A3 in Fig. 2) If several such data sets D are found, a suitable one, for example the most energy-efficient, can be selected according to defined criteria. If several data sets D, fulfilling the same conditions mentioned above except for power consumption, are stored in data storage 19, data sets D from production situations D that are less suitable according to defined criteria can be selected. P , D B* , V, e.g. those with a higher energy consumption compared to the most economical operation, are deleted.

[0026] The operating parameters D contained in the found or selected data set D B* are taken over for further operation by the control means 22 of the machine control or at least suggested to the operating personnel for takeover, in particular at the display device 26 (see e.g. step A6 in Fig. 2) After the takeover, a reprint is then carried out, for example, with the taken-over operating parameters D. B* .

[0027] Preferably, in addition to the product-specific properties D P The current production speed V is also transmitted to the energy efficiency system 16 and used in the search for an alternative production situation D. P , D B* , V is taken into account in such a way that, according to a data set D, both with the same product-specific properties D P as well as a similar production speed V is sought.

[0028] The recording of the total performance and the check for the existence of an existing data set D with a value compared to the current total performance P G smaller total electrical power P Gcan be carried out routinely at a fixed time, e.g. after a defined progress in production, for example when 60% of the order volume has been completed, by the energy efficiency system 16 itself or at any time on request by the operating personnel.

[0029] The described procedure is used, for example, in Fig. Figure 5 illustrates where, for example, after the machine has been started up, it is initially operated at a production speed V of 15,000 substrate sheets S per hour (B / h) (see, for example, state Z1 at time 10:00 a.m. in Fig. 5b)), and the production speed V is subsequently increased to 18,000 substrate sheets S per hour (state Z2 at the relevant time). As a result of a routine check or a check initiated by operating personnel for more energy-efficient operation, or as a result of exceeding a threshold value, the energy efficiency system 16 in the data memory 19 generates a new set of operating parameters D B* searched, found (see highlighted record “0088” in the table from Fig. 4) and automatically or by confirmation, in which, for example, the dryer output P 14 The second dryer 14, at a constant production speed V, is at "zero", meaning that dryer 14 is switched off and therefore not essential for proper production in this case (state Z3). The data for state Z3 at the measurement time are in Fig. 5a) highlighted and reflect the affected production situation with the adopted operating parameters D B again.

[0030] Based on the further course of events in Fig. 5 illustrates further training for the evaluation or verification of the measurement results from performance measurement, according to which, in the event that during recurring measurements of the total performance P G during an otherwise unchanged production situation D P , D B , V a significant increase in the determined total power P G is determined (see e.g. condition Z4 in Fig. 5b)), a fault or maintenance requirement is inferred for at least one component of the machine which is operated or designed by a consumer 08; 09; 12; 13; 14 integrated into the measurement. The existence of a fault can already be determined from the evaluation of the total power P GThe limitation to the potentially affected consumer 08; 09; 12; 13; 14 or the component trained or operated by the consumer in question 08; 09; 12; 13; 14 can be determined, however, only if, in an advantageous embodiment, several measuring devices 18 are provided for the consumers 08; 09; 12; 13; 14 or groups. In the example, despite, for example, a manual or energy efficiency system 16-induced reduction in the production speed V, there is even a further, albeit weakened, increase in total power P. G to determine (see e.g. state Z5).

[0031] In the event that, in the above question from step A3, no data set D has yet been found for such a production situation D P , D B* , V with comparable product-specific properties D P with lower total electrical power P GIf a new data set D is available, for example, one containing the currently available product-specific properties D will be created. P , the current operating parameters D B , the current production speed V and the D for this production situation P , D B* , V present total output P G transferred to data storage 19 (see e.g. step A4 in Fig. 2) For example, printing continues with the existing operating parameters D. B .

[0032] In this way, System 16 grows with a self-optimizing database, in which data for a wide variety of productions with different product-specific properties is stored. P and, if applicable, production speeds V, continuously improved operating parameters D B are maintained and accessible for energy-saving operation. A schematic example of such a database is shown, for example, in Fig. 4 explained and stored, for example, in database 19.

[0033] Preferably, one or more drive motors 08; 09 of the components 06; 07; 11 serving substrate conveying and / or processing of the machine and / or one or more electrically operated dryers 13; 14 and / or a compressor 12 for the supply of compressed air or other pressurized fluids and / or one or more lighting devices and / or an air conditioning device and / or a temperature control device for process fluids are used in the described method or device for increasing efficiency, i.e., performance measurement and testing of the production situation D. P , D B , V towards an alternative, more economical production situation D P , D B* , V; D P , D B , V* with lower total power P G included.

[0034] Instead of or in addition to the routine or operational personnel-initiated measurement of total power and testing for a more energy-saving alternative for the selection of operating parameters D B This can happen during production (see e.g. step B1 in Fig. 3) a check for the existence of an existing data set with a smaller total electrical power P G This can also be triggered by the fact that during a routine determination and testing of the overall performance P - e.g., continuous or recurring G an exceedance of a specified threshold for the permitted total power P G is determined (see e.g. step B2 in Fig. 3) If such an exceedance is detected, a data set D of an alternative production situation D is used in the manner described above – preferably assuming a constant production speed V. P , DB* , V sought (step B3), whose total power P G below the threshold, and in the event of success, their operating parameters D B* , and e.g. directly or possibly after an initial proposal (step B4) adopted into the control means 22 controlling the machine, whereupon the printing continues with the new operating parameters D B* This is done. (Step B5).

[0035] However, in the event that no data record D for such a production situation D exists in step B3 P , D B* , V with comparable product-specific properties D P and the same production speed V with lower total electrical power P GIf a certain condition is detected, the production speed V is reduced, for example. This reduction can be carried out – e.g., based on a recommendation from the database system 16 at the display unit 26 – via manual intervention by the operating personnel at the or another operating interface 24.

[0036] In an advantageous further development, however, the throttling is directed towards a search for a data record D already stored in data storage 19, for which in a production situation D P , D B , V* with comparable product-specific properties D P and operating parameters D B the total power P Gat the smallest possible reduced production speed V* below the threshold value (step B6). This means that the data set D with the smallest reduction in production speed V is selected from potentially several possible data sets. The production speed V* present in the found or selected data set D is either directly adopted by the control elements 22 of the machine control system for further operation or at least suggested to the operating personnel for adoption (step B7). After adoption, printing continues with the reduced production speed V* (step B8).

[0037] If, in the above configuration of the machine, only one higher-level power measuring device 17 is provided, the power consumption of individual consumers 08; 09; 12; 13; 14 or groups of consumers can be derived from a comparison of different production or operating situations stored in the data memory 19 and stored in the data memory 19. If, for example, the machine requires 100 kW of power with two active dryers 13; 14 in a specific production run, but only 90 kW with only one active dryer 13; 14 under otherwise comparable conditions, the inactive dryer 14; 13 can be measured with a power P 14 ; P 13 Assuming a power output of 10 kW, this can be stored, for example, in a different table of the data storage or within a functional context. A power output P 08The main drive 08 can be determined, for example, by a separate measuring device 18 or, if necessary, in idle mode, i.e., without the operation of the other units or components.

[0038] Instead or in addition to this, the total power consumption P can be determined from comparable productions with different production speeds using the stored data sets D. G derive and record in a table or functional relationship which production rate V yields which total output P for comparable production processes. G is retrieved. Such a list or dependency can also be used, for example, to derive a proposal for a desired or necessary saving, especially if no directly comparable production data is stored for the current production situation.

[0039] A machine, particularly suitable for carrying out the described process, for processing and / or manufacturing web- or arc-shaped substrate S, which includes a plurality of electrical power consumers 08; 09; 12; 13; 14, is therefore assigned an energy efficiency system 16 supporting the efficient operation of the machine, which includes a data storage system 19 in which past production situations D P , D B , V descriptive data sets D are kept, which at least contain data on product-specific properties D P , to a production speed V, to the operating parameters D concerning consumers 08; 09; 12; 13; 14 B and to a total power output P achieved through this G to include. Furthermore, at least one measuring device 17; 18 is provided, by which, during operation, the current production situation D P , D B, V a current consumption of total power P taken in by the majority of consumers 08; 09; 12; 13; 14 G The energy efficiency system 16 is connected to the control means 22 that control the machine and to the control means or means that determines the total power P. G Determining measuring devices 17; 18. The energy efficiency system 16 comprises data processing equipment 21, which is designed to process data transmitted from the control equipment 22, at least regarding the product-specific properties D P and to the overall performance P G to then check whether a data record D for a production situation D already exists in data storage 19 P , D B* , V with comparable product-specific properties D P with a smaller total electrical power P Gis present, and in the event of success, i.e., in the event that such a data record D is found or can be found, the operating parameters D contained in the or a found data record D B* to hand over to the control means 22 for further operation or to propose to the operating personnel at a display device 26 for takeover.

[0040] Preferably, the data processing means 21 are configured to process data transmitted from the control means 22 relating to both the product-specific properties D P as well as to check whether a data record D for a production situation D already exists in data storage 19, in addition to the current production speed V. P , D B* , V with comparable product-specific properties D P at the same production speed V, but with a lower total electrical power P Gis present, and if successful, the operating parameters D contained in a found data set D B* to transfer the data to a machine control 22 for continued operation at unchanged production speed V, or at least to suggest it to the operating personnel at a display device 26 for takeover.

[0041] Advantageously, an operating interface 24, which is connected to the control means 22 and the energy efficiency system 16 via signal technology, is provided with at least one mechanically or touch-sensitive button, by the actuation of which a suggestion displayed on the display device 26 can be selected and / or accepted.

[0042] As an alternative or supplementary further development to the above procedure, which is based solely on a comparison with previous production situations, it is possible – e.g., in a different operating mode of system 16 – to use information stored in data memory 19 on the power consumption of individual consumers 08; 09; 12; 13; 14 or consumer groups and / or on the basis of or using the determined speed dependency of the total power P G The machine can be operated in an energy-efficient manner by adjusting the total electrical power P in case the machine currently requires more power. G consumed as defined by the above threshold as a maximum, by means of the data processing means 21 included in the energy efficiency system 16, via appropriately configured software, a modified set of operating parameters D Band / or a speed V is determined and, if necessary, suggested that ensures reduced power consumption below the threshold. This could be, for example, a calculated reduction in production speed V*, reduced dryer capacity, a lower blowing or suction air setting, or a combination of several measures. The selection of the most suitable measure(s) can be determined using fixed rules and priorities, dependencies based on fuzzy logic, and / or self-learning algorithms, such as AI-based algorithms.
