Abstract

The invention relates to a sheet processing machine and a method with a device for determining the consumption of ink and/or varnish, the sheet processing machine having several application units and a feed system being arranged to supply the several application units with ink and/or varnish from at least one container, wherein the at least one container is arranged in an operative connection with at least one weight measuring device and wherein the at least one weight measuring device is arranged coupled to a control unit of the sheet processing machine, wherein the at least one control unit uses the at least one weight measuring device to determine at least one ink consumption and/or varnish consumption per print job and/or or arranged to determine per printed copy.

Description

The invention relates to a sheet processing machine with a device for determining the consumption of ink and/or varnish according to the preamble of claim 1 and a method for operating a sheet processing machine with a device for determining the consumption of ink and/or varnish according to the preamble of claim 1 claim 12.

A wide variety of printing fluids or printing inks and/or paints are used in printing machines. During printing, the printing fluids are applied to a printing material. In this case, the pressure fluids are usually fed to the application units, for example printing units or coating units, from larger paint or coating containers.

through the DE 10 2005 058 768 B4 an automated monitoring of the amount of paint or the amount of paint is disclosed. For this purpose, the filling level of the container of the or each printing unit and/or coating unit is detected by means of a filling level sensor during the printing operation. The amount of paint and/or varnish used is determined from this data. For this purpose, the printing machine is equipped with an inline measuring system. For example, the amount of varnish or ink per printed copy can be determined from the data. Furthermore, the inline consumption measurement of paint or printing ink can be used in a logistics system for automated logistics control. In addition, information about contamination, for example on anilox rollers, or incorrect press settings can be obtained from the data. Alternatively, the fill level can also be recorded indirectly with a flow sensor.

Furthermore, through the WO 2005/077657 A1 discloses a method for accurately measuring the ink consumption of a printing press. Ink consumption is usually determined by measuring the weight before and after a print job. For example, the price per print job can be calculated from this data. The data can be shown to a plant operator on a display of a control station, for example. The data can also be transmitted wirelessly.

Furthermore, through the EP 0 227 232 A2 a system for monitoring the pressurized fluid supply system is known. Floor scales and/or flow sensors are used for this. As a result, the pressure fluid consumption can be analyzed precisely.

The object of the invention is to create a sheet processing machine with a device for determining the consumption of ink and/or varnish and a method for operating a sheet processing machine with a device for determining the consumption of ink and/or varnish.

The object is achieved according to the invention by the features of claim 1 and claim 12 respectively.

An advantage that can be achieved with the invention consists in particular in the fact that the consumption quantity of different printing fluids, such as printing inks or varnishes, can be determined in printing presses in a simple manner. For this purpose, the weight of the paint or varnish container provided is determined at least before and after each print job. From this, the consumption quantity of the lacquer or paint can be derived, taking into account all rheological parameters. The device for determining the amount of pressurized fluid is particularly simple, inexpensive and can be set up universally. The device has many evaluation and linking options. In particular, the consumption quantity per print job and in particular per printed copy can also be determined and printing ink or ink can be supplied to the printing machine in a targeted manner or the supply can be stopped in good time. It is also easy to check that there is always sufficient lacquer or paint in the container or container. The logistics of means of production can also be optimized using the data, preferably via intelligent systems. Such an intelligent system is preferably characterized by the ability to learn, autonomy, error tolerance, etc. Artificial intelligence methods are preferably used in such an intelligent system.

A floor scale installed directly on the machine can be used particularly preferably. The paint or varnish containers are preferably placed directly on such a floor scale. In a preferred embodiment, the at least one floor scale has a unit for wireless data transmission, for example to a control unit of the sheet processing machine or to a memory unit. In this way, transmission to mobile devices can also take place in a simple manner.

The weight measuring devices are coupled to a control unit and/or at least to the control station. Various machine parts derived from the data can then be controlled and/or regulated. The data can be sent wirelessly to the controller, for example be transmitted. The at least one floor scale is preferably coupled at least in terms of data technology to a controller for the paint supply and/or a chamber doctor blade.

A further advantage that can be achieved with the invention consists in particular in the fact that the at least one floor scale can be linked in terms of data technology to a mobile terminal device. For example, the data can be displayed on an application of the terminal device and, for example, recommendations for action can be given to the operator. In this case, the data can easily be transmitted wirelessly from the weight measuring device.

A further advantage that can be achieved with the invention is that the weight measuring device is arranged coupled directly or indirectly via the control of the machine to a logistics control for means of production. Such means of production are preferably means required for the production itself and/or means required for upstream and/or downstream processing operations. In addition, data from the machine, such as the number of sheets to be processed and/or sheets already processed, as well as a production plan, are available to the logistics controller. From this, the consumption per print copy can be precisely determined and an exact consumption forecast can be derived. For example, precise consumption planning for the sheet processing machine can be provided by means of various evaluation methods or preferably by means of artificial intelligence. For example, the supply of paint and/or varnish can be adapted to future consumption and a supply can be switched off in good time and in an optimized manner, so that cleaning of application units is made easier, for example. For example, the production plan can also be automatically changed and/or optimized from the consumption quantities via the logistics control, preferably by means of artificial intelligence. In particular, the degree of automation of the sheet processing machine can be further increased and manual entries by the operator can be avoided. In particular, an improved production process or an improved supply of paint and/or varnish is achieved with the aid of the data from the at least one weight measuring device, for example through machine learning or through neural networks. Deviations or errors in the setting of the machine can also be easily recognized by the artificial intelligence.

An embodiment of the invention is shown in the drawings and is described in more detail below.

The sheet-shaped substrate B or the thus defined Here sheet B is preferably made of paper or cardboard, ie as a sheet of paper or cardboard, but can in principle also be formed by sheets B, panels or possibly plates made of plastic, cardboard, glass or metal.

For the sake of simplicity, in the foregoing and in the following - unless explicitly differentiated and named accordingly - the term "printing ink" should be understood in the sense of a liquid or at least free-flowing coloring fluid to be printed in a processing machine 01, in particular a printing machine 01, which not only refers to the higher-viscosity coloring fluids for use in rotary printing machines, which are more colloquially associated with the term "printing ink", but in addition to these higher-viscosity coloring fluids, in particular also low-viscosity coloring fluids such as "inks", especially inkjet inks, but also powder-form coloring fluids such as e.g. B.

toner, includes. In the foregoing and in the following, colorless lacquers are also meant in particular when printing fluids and/or inks and/or printing inks are mentioned. In the foregoing and in the following, means for a pretreatment (so-called priming or precoating) of printing substrate 02 are also preferably meant when printing fluids and/or inks and/or printing inks are mentioned. As an alternative to the term pressure fluid, the term coating agent is to be understood synonymously.

The individual components of a sheet-fed processing machine on a sheet-fed printing press are described in more detail below.

such as Am 1 and or 2 shown, a substrate feeder 01 embodied as a sheet feeder 01 is shown, with a conveyor section 02 embodied, for example, as a belt table 02, and with a printing substrate container 09 formed by a stack of sheets 09, for example, which is arranged on a receiving device 10, e.g. B. a stacking plate 10 is placed. The stacking plate 10 is connected to transport means 11, which ensure that the top of the stack of sheets 09 is held in a defined position.

In one embodiment, individual drives are provided for the separating suckers 12 and the transport suckers 13 . Individual drives are understood here as controllable drives which are assigned to one or a group of working elements (sheet separating elements 12 and/or sheet transport elements 13) to drive them, in particular to drive them independently of the drive (preferably all) other working elements or groups of working elements, in particular without to be coupled via a mechanical and/or positive drive connection to drives of other working elements that are driven individually or also in one or more groups.

Sheets B of the stack of sheets 09 are positioned on stop elements 16, in particular with the front edge of the sheet on stop surfaces of front stops 16. A sheet flap 17 can form an approximately vertical continuation of the stop surfaces of the front stops 16 in the upper region of the stack of sheets 09. The curved flap 17 is, for example, via a flap shaft 18, to which it is connected in a rotationally fixed manner, in drive connection with a drive, preferably an individual drive. The sheet flap 17 can thus be pivoted out of the position forming a straight continuation of the stop surfaces and thus brought into a position that supports the guidance of the sheets B to the downstream belt table 02.

This intermediate drying can also be carried out by a drying unit arranged in the machine.

The sheet delivery 08 of a sheet-processing machine, in this case in particular a sheet-fed printing press, in particular a sheet-fed offset rotary printing press, contains a sheet-guiding system 69 arranged downstream of a sheet-guiding system, in this case as a sheet-guiding cylinder, specifically impression cylinder 34, which is embodied in particular as a chain conveyor system 69. The sheet conveying system 69 contains traction means which are moved via drive and deflection means and which drive gripping devices 70 for sheet conveying. The gripping devices 70 have fixing elements for taking over and fixing the sheets B. In particular, clamping and/or suction grippers can be used as fixing elements for gripping the edges of the sheet. In not shown developments are provided additional gripping devices for the sheet trailing edges.

The sheet conveyor system 69 embodied here as a chain conveyor system 69 contains chains 73 which are laid over sprockets 72 and are driven by them and are guided in laterally arranged guide rails (not shown), on which a gripper device 70, in particular a plurality of gripper carriages 70 for transporting the sheets B are arranged. The gripper carriages 70 convey the sheets B in the sheet transport direction 15 to the delivery pile 71, which is stored on a pallet 76 or another type of transport base, for example. The gripper carriages 70 preferably contain leading edge clamping grippers which have gripper fingers which interact with gripper supports and which are arranged at a distance from one another on a gripper shaft and can be controlled by this.

A sheet guiding device and, for example, a dryer are provided in the sheet delivery 08 to ensure that the sheets B held by the gripper carriages 70 are transported safely. The sheet guiding device has sheet guiding plates facing the gripper carriage 70, which are provided with blast air nozzles and extend across the width of the machine. Blower boxes are arranged under the sheet guide plate, via which the blown air nozzles are supplied with blown air, so that a supporting air cushion is formed between the sheet guide plate and the sheets B transported by the gripper carriage 70 . In order to be able to regulate heating of the sheet guide plate in the area of the dryer, a coolant circuit can be integrated. In order to prevent the sheets B from sticking together on the delivery pile 71, a release agent application device, in particular a powder device, preferably combined with a device for sucking off the powder, is preferably provided in the area of the sheet delivery 08.

In front of the delivery pile 71 there is a braking device, not designated further, for decelerating the sheets B released by the gripper carriage 70 . The braking device can contain rotating suction rings and/or circulating suction belts or can be designed as a follow-up gripper system. The sheets B decelerated by the braking device come into contact with front stops and are thus deposited on the delivery pile 71 in an aligned manner. The delivery pile 71 is preferably lowered by a pile lifting drive by the thickness of the deposited sheet, so that the surface of the pile always assumes an approximately constant level.

To change the z. B. transport documents 76 designed as pallets 76 to avoid stopping the sheet-fed printing press, the sheet delivery 08 can be equipped with a non-stop device, not shown. This mainly includes an auxiliary stack carrier, for example in the form of a slatted table that can be rolled up, in particular also referred to as a roller blind. The roller blind has rods which are movably connected to one another. In its rest position, it is arranged rolled up in front of the delivery pile 71 and is unrolled between two sheets B into a working position lying parallel to the surface of the delivery pile 71 to change the pile while the sheet-fed printing press is running in the sheet transport direction 15 . In this position above the delivery pile 71, this lattice table temporarily accepts the incoming sheets B, so that an auxiliary pile is formed. In the meantime, the main stack can be removed and replaced by a new transport base 76, in particular a pallet 76. At the end of the stack changing process, the roller blind is pulled back into its rest position and the auxiliary stack is placed on the new pallet 76.

At least one drive motor (not shown) is assigned to the sheet-fed printing press.

In a first embodiment, this is at least one drive motor z. B. designed as a main motor and drives z. B. a closed train of wheels that forms a drive network. The drive assembly includes in particular the pressure cylinder 34; 36, the transfer drums 35, the blanket cylinders 33, the plate cylinders 32, the coating unit 07 and the inking units 42.

Individual functional units of the sheet-fed printing press, such as the substrate feed system 01, specifically the sheet feeder 01, the ink pick-up roller 44 and/or any dampening units 51 provided, can preferably be connected to the drives of the other functional units and the drive system comprising the main motor, are or be driven. In an embodiment that develops the first embodiment, at least the plate cylinders 32 are separated from the drive system and replaced by separate drives assigned only to the respective plate cylinder 32, in particular individual drives, i.e. without a mechanical and/or positive drive connection to the drives of the other plate cylinders 32 and to the main motor comprehensive drive system and to drives other functional units such as the substrate supply device 01, the ink fountain rollers 44 and/or the dampening units 51. The individual drives of the plate cylinders 32 can in particular be formed by so-called direct drives, the direct drive being understood to mean an above-mentioned individual drive in which the drive motor or its rotor is connected to the drive shaft, in particular the journal, of the plate cylinder 32, preferably without intermediate gear elements, directly or possibly via a coupling in a mutually coaxial arrangement. The drive motor is preferably designed in such a way that the interposition of a gear can be dispensed with. The peripheral speed of the plate cylinders 32 is adapted to the peripheral speed of the cylinders interacting with the plate cylinders 32 . According to another embodiment, several of the works 05; 06; 07, preferably any of the works 05; 06; 07 its own, the drive network of the relevant plant 05; 06; 07 driving drive motor, but without a mechanical and/or positive drive connection to drives of other movements 05; 06 to be paired. For example, the coating unit 07 also has at least one drive of its own. Such a drive is, for example, a direct drive and/or an auxiliary drive. Such an auxiliary drive can preferably be decoupled from the main drive and used, for example, to position individual cylinders, in particular the forme cylinder 63 .

• Die Bogenvereinzelungsorgane 12 werden gegen die Oberseite des Bogenstapels 09 geführt, erfassen den jeweils obersten Bogen B und heben diesen vom darunter liegenden Bogen B ab, indem sie in ihre Ausgangslage zurückbewegt werden. Die Bläser unterblasen den von den Bogenvereinzelungsorganen 12 gehaltenen Bogen B und trennen diesen so vollflächig vom darunter liegenden Bogen B. Der von den Bogenvereinzelungsorganen 12 gehaltene und vollflächig getrennte Bogen B wird von den Bogentransportorganen 13 erfasst und von den Bogenvereinzelungsorganen 12 freigegeben. Die Bogentransportorgane 13 fördern den erfassten Bogen B in Bogentransportrichtung 15, wobei mit Beginn des Bogentransports die Bogenklappe 17 nach unten geschwenkt werden kann, so dass der Bogen B mit der Bogenvorderkante zur z. B. als Bändertisch 02 ausgebildeten Förderstrecke 02 transportiert werden kann. Die Taktrollen 25 sind anfänglich von der Antriebswalze 20 abgehoben und setzen auf den jeweiligen Bogen B auf, wenn dieser sich im Spalt zwischen den Taktrollen 25 und der Antriebswalze 20 befindet. Anschließend wird der jeweilige Bogen B von den Bogentransportorganen 13 freigegeben. Die von den Bogentransportorganen 13 in Bogentransportrichtung 15 geförderten Bogen B werden unter Einhaltung eines vorgegebenen Schuppenabstandes auf der z. B. als Bändertisch 02 ausgebildeten Förderstrecke 02 positioniert und von diesem bzw. dieser im Arbeitstakt der Bogendruckmaschine gegen die Vordermarken 27 geführt und können nachfolgend durch die beispielsweise als Schwinggreifer 04 ausgebildeten Bogenbeschleunigungsmittel 04 abgezogen werden.

The sheets B are in the z. B. provided as a stack of sheets 09 09 to be printed. The uppermost sheet B of the stack of sheets 09 is grasped by the sheet separator 14 and forwarded for further processing. This happens e.g. B. as follows:

• The sheet separating elements 12 are guided against the top of the stack of sheets 09, grasp the uppermost sheet B and lift it off the underlying sheet B by being moved back into their starting position. The blowers blow under the sheet B held by the sheet separating elements 12 and thus separate it over its entire surface from the underlying sheet B. The sheet B held by the sheet separating elements 12 and separated over its entire surface is gripped by the sheet transport elements 13 and released by the sheet separating elements 12. The sheet transport elements 13 promote the detected sheet B in the sheet transport direction 15, with the beginning of the sheet transport, the sheet flap 17 can be pivoted downwards, so that the sheet B with the sheet leading edge to the z. B. designed as a belt table 02 conveyor line 02 can be transported. The timing rollers 25 are initially lifted from the drive roller 20 and set down on the respective sheet B when this is in the gap between the timing rollers 25 and the drive roller 20. The respective sheet B is then released by the sheet transport elements 13 . The supported by the sheet transport members 13 in the sheet transport direction 15 sheets B are in compliance with a predetermined scale spacing on the z. B. configured as a belt table 02 conveyor line 02 and guided by this or this in the work cycle of the sheet-fed printing press against the front lays 27 and can then be drawn off by the sheet acceleration means 04 embodied, for example, as a rocking gripper 04.

The grippers z. B. of the swing gripper 04 transfer the sheet B to the gripper of the feed drum 29, through which the sheet B is transferred to the gripper system 57 of the impression cylinder 34 of the first printing unit 05.

• Die im z. B. im als Farbkasten 43 ausgebildeten Farbvorrat 43 bevorratete Farbe, insbesondere Druckfarbe wird zonenweise dosiert auf die Farbaufnahmewalze 44, z. B. Farbkastenwalze 44, gebracht und bevorzugt von dem periodisch hin und her bewegten Farbheber 47 als Farbstreifen auf die z. B. als Farbreibwalze 48 ausgebildete erste Farbwerkwalze 46 abgelegt. Diese überträgt die Farbe über durch Friktion angetriebene Farbwerkwalzen 49 auf die Farbreibwalzen 48. Über weitere Farbwerkwalzen 45 wird die Farbe auf die Farbauftragswalzen 50 übertragen und gelangt dadurch auf die auf dem Formzylinder 32 aufgespannte Druckform, wobei in Drehrichtung 53 des Formzylinders 32 gesehen vor dem Auftrag der Farbe durch die Farbauftragswalzen 50 der Auftrag von Feuchtflüssigkeit durch die Feuchtauftragswalze 52 erfolgen kann.

The sheet B now on the impression cylinder 34 is inked by the inking unit 42 via the forme cylinder 32 and in the form of an offset printing unit via the transfer cylinder 33 . This happens e.g. B. as follows:

• The z. B. designed as an ink fountain 43 color reservoir 43 stored color, especially ink is zoned metered onto the ink pickup roller 44, z. B. ink fountain roller 44, and preferably brought by the periodically reciprocating ink lifter 47 as a color stripe on the z. B. formed as an inking roller 48 first inking unit roller 46 is stored. This transfers the ink via friction-driven inking unit rollers 49 to the inking rollers 48. The ink is transferred to the inking unit rollers 50 via further inking unit rollers 45 and thus reaches the printing forme clamped on the forme cylinder 32, with this before the application as seen in the direction of rotation 53 of the forme cylinder 32 of the color through the inking rollers 50, the application of dampening liquid through the dampening form roller 52 can take place.

The color deposited on the printing form is transferred to the blanket cylinder 33 in accordance with the motif and from there to the sheet B guided by the impression cylinder 34 .

• Der Bogen B wird von dem Greifersystem 57 des Druckzylinders 34 an das Greifersystem 59 der Übergabetrommel 35 übergeben und so weiter durch die gesamte Bogendruckmaschine geführt. In den einzelnen Druckwerken 05; 06 wird dann über die betreffenden Übertragungszylinder 33 die Farbe auf den Bogen B aufgebracht.

The sheet B is now transferred from the first printing unit 05 to the following printing unit 06 and, if necessary, subsequent further printing units. This happens e.g. B. as follows:

• The sheet B is transferred from the gripper system 57 of the impression cylinder 34 to the gripper system 59 of the transfer drum 35 and so on through the entire sheet-fed printing press. In the individual printing units 05; 06, the ink is then applied to the sheet B via the relevant transfer cylinder 33.

• Der auf der Speichertrommel 80 liegende, im Schöndruck bedruckte Bogen B wird vom Bogenhaltesystem 83 im Bereich der Bogenvorderkante geführt und zusätzlich von einem als Sauggreifer des Saugersystems 84 ausgebildeten Bogenhaltesystem 84 im Bereich der Bogenhinterkante fixiert. Nachdem die Bogenvorderkante den Tangentenpunkt zwischen Speichertrommel 80 und der nachfolgenden Wendetrommel 81 passiert hat, wird sie vom Bogenhaltesystem 83 freigegeben. Während die Bogenhinterkante den Tangentenpunkt zwischen Speichertrommel 80 und Wendetrommel 81 passiert, wird sie vom Wendegreifersystem 82 der Wendetrommel 81 übernommen und vom Bogenhaltesystem 84 der Speichertrommel 80 freigegeben, so dass die Bogenhinterkante dann zur Bogenvorderkante wird.

On the way of the sheet B through the sheet-fed printing press, if a turning device 78 is present, the sheet B can also be turned and printed on its back. The operation of the sheet holding system described in the embodiment in the perfecting mode is z. B. the following:

• The straight-printed sheet B lying on storage drum 80 is guided by sheet holding system 83 in the area of the sheet leading edge and additionally fixed by a sheet holding system 84 designed as a suction gripper of suction system 84 in the area of the sheet trailing edge. After the leading edge of the sheet has passed the tangent point between the storage drum 80 and the subsequent turning drum 81, it is released by the sheet holding system 83. While the trailing edge of the sheet passes the tangent point between storage drum 80 and turning drum 81, it is taken over by the turning gripper system 82 of the turning drum 81 and released by the sheet holding system 84 of the storage drum 80, so that the trailing edge of the sheet then becomes the leading edge of the sheet.

After the sheet B has passed the printing units 05; 06 has passed, it can be provided with a coating layer in one or more coating units 07 by the coating forme cylinder 63. The gripper system of the pressure cylinder 61 then transfers the sheet B to z. B. the chain conveyor system 69 of the sheet delivery 08.

The gripped at the leading edge sheets B are z. B. out on a track that faces up. The sheets B are dried by the drying devices 68 provided and z. B. covered with powder. The sheets B are transported by the gripper carriage 70 up to the height of the delivery pile 71 and deposited there on it.

Each printing unit 05; 06 has the semi-automated and/or automated plate changing device 41. Via such a plate changing device 41, the respective printing unit 05; 06 Printing plates supplied and/or printing plates changed. When a printing plate is changed, for example after the end of a print job, a printing plate clamped on the forme cylinder 32 and held by the fastening means 40 is released and guided out of the printing press via the plate changing device 41 . A new printing plate is then introduced, preferably automatically, into the printing press by the plate changing device 41 and clamped on the forme cylinder 32 by the fastening means 40 . The plate change can be detected in a control device by various sensors. As a result, processes stored in the control device can be started. Such a process is, for example, degumming and/or developing a printing plate in the printing press.

The at least one sheet processing machine 01 has an ink supply system 100. Each commissioned unit 05; 06; 07, in particular each printing unit 05; 06 and/or each coating unit 07 has at least one supply line 103 coupled to at least one container 102 for supplying paint and/or coating. The at least one container 102 for coating unit 07 is preferably embodied as a paint container 102 and is filled with a paint. The at least one container 102 is preferred for the printing units 05; 06 is preferably designed as an ink tank 102 and filled with a printing fluid or printing ink. Each container 102 is preferably operatively connected to a weight measuring device 101 . Such a weight measuring device 101 is preferably designed as a floor scale 101 . The weight measuring device 101 preferably has a high measurement uncertainty of at most ±8 kg, more preferably at most ±2 kg.

Each weight measuring device 101 is preferably arranged coupled to a control unit 104 of the sheet processing machine. Additionally or alternatively, the weight measuring devices 101 are coupled to a control station, in particular a display device, preferably a control station. For example, the consumption of varnish and/or paint can be displayed and/or monitored and/or the supply can be regulated or controlled. For this purpose, the at least one weight measuring device 101 preferably has a unit for wireless data transmission to a controller 104 or to at least one mobile terminal device. As an alternative or in addition, the data is transmitted to the controller 104 conventionally using cables and is then transmitted from there either wirelessly or by cable connection, for example to a control station or to a mobile terminal device. Multiple evaluation methods are preferably stored in the control unit 104, with which processed data are transmitted to the control unit 104 or the mobile terminal device. Real-time data is preferably transmitted. This is an intelligent system. Such an intelligent system is characterized by: ability to learn, autonomy, error tolerance, etc.

Additionally or alternatively, each weight measuring device 101 can be coupled directly or indirectly to a mobile terminal device. For this purpose, for example, the paint or varnish consumption can be recorded on the mobi end device can be monitored. For example, the supply of paint and/or varnish can be controlled and/or regulated.

The at least one weight measuring device 101 measures the weight of the container 102 automatically and preferably permanently, in particular during machine operation. At least the at least one weight measuring device 101 measures the weight at least before and after a print job. By coupling to the control unit 104, information can be obtained about how many sheets or prints are being produced. In particular, the number of sheets that have been printed and the change in the weight of the container 102 can be used to calculate how much ink or varnish is required per printed copy. For example, the consumption can be shown on a display of the control center and support an operator in his decisions. The at least one weight measuring device 101 is preferably coupled directly or indirectly via the at least one control unit 104 to a logistics controller. Such a logistics control coordinates and/or controls, in particular, upstream and/or downstream processes and the provision of means of production in the sheet processing machine. In particular, a means of production logistics can be controlled with the logistics control. Means of production are all means that are used in production or that are required for production. For example, a production plan can be stored in the logistics control. This indicates in which order and in which process the production is run. Based on this, means of production are provided. For example, fully automated printing plate logistics can transport printing plates to the machine at exactly the right time in coordination with the production plan. Fully automated color and/or paint changes can also be prepared. In particular, the data from the at least one weight measuring device 101 can be used to optimize the production process, for example. To be optimized in particular so that frequent cleaning of the ink and/or coating unit can be avoided. More preferably, the consumption of paint and/or varnish is automatically determined by coupling the weight measuring device 101 to a logistics controller, and the consumption of paint and/or varnish can be coordinated with a production plan. Paint and/or varnish can then be provided via the logistics control without manual intervention. The supply of ink can also be restricted, preferably via the control unit 104, if a print job requires a change of ink and/or varnish, for example. In this way, a commissioned unit 05; 06; 07 be prepared and simplified. In particular, program sequences for the automatic control of the sheet processing machine are integrated in the controller.

The at least one weight measuring device 101 is preferably connected directly or more preferably indirectly via the control unit 104 to the at least one controller of a chamber doctor blade of the application units 05; 06; 07 arranged coupled. Based on this, for example, the squeegee can be set or adjusted.

Additionally or alternatively, the data from the at least one weight measuring device 101 is processed in the control unit 104 . For example, methods of artificial intelligence or machine learning are used in order to use the data from the weight measuring device 101 in an improved manner. Various solutions for increased automation of the sheet processing machine can be derived from the data. On the one hand, various recommendations for action for an operator can be displayed via the evaluation methods, for example at a control station or on an application of a mobile terminal device. Preferably, real-time data from the at least one weight measuring device 101 can also be displayed. More preferably, the data from the at least one weight measuring device 101 is converted directly into paint or varnish consumption. In particular, a precise coating and/or ink consumption for each individual printed copy can be determined through the coupling with the machine control and the information on the printed sheets. In addition, the data of the paint or varnish consumption is stored in a storage unit. Future consumption can be determined based on the production plan using various evaluation methods such as regression and/or machine learning or neural networks. For example, a paint and/or varnish supply can then be adjusted automatically. Alternatively or additionally, an optimized form of the production plan can be proposed, or a new production plan can be created automatically. In a particularly preferred manner, the preparation, in particular the provision of means of production, can then also be optimized and further processing can also be adapted to the optimized production process. Errors or misalignments in the production process, for example a faulty printing press, can also be recognized and/or identified and/or dealt with accordingly due to a deviating ink or varnish consumption. Using the data from the weight measuring device 101, the production plan can be optimized in particular to the effect that the cleaning steps of commissioned units 05; 06; 07 can be reduced or prevented.
