Abstract
Description
[0001] The invention relates to a method for checking and / or adjusting a bearer ring pressure in a measuring system according to the preamble of claim 1 and a measuring system according to the preamble of claim 16.
[0002] During printing, the plate cylinder and blanket cylinder of a printing unit roll against each other. The blanket cylinder, in turn, is in pressure contact with an impression cylinder. Due to the cylinder channels present in the cylinders, fluctuations in the applied forces occur. This fluctuation in pressure between zero and the maximum value is also referred to as "channel runout". Bearer rings are used on the front sides of cylinders rolling against each other to create an additional bearing point with closer bearing spacing and thereby reduce the amplitude of vibrations caused by channel runout. The bearer rings of the adjacent cylinders roll against each other. The relative pressure of the bearer rings on each other is also referred to as the preload of the bearer rings. For example, the pressure can be adjusted using an adjusting spindle. In an exemplary design, stops determine the adjustment range of the adjusting spindle.Precise adjustment of the pressure between the bearer rings is crucial. If the pressure is too low, pressure-related problems arise. If the pressure is too high, damage or a shortened service life of the bearings and / or the bearer rings themselves can result.
[0003] The basic setting of the press force is performed during printing tower assembly. For example, a colored medium, such as ink, is applied to the bearer rings of a plate cylinder at the transition between the channel and the outer surface. Starting from a basic position, the pressure is increased until the colored medium forms a shape determined by comparison images on the bearer rings. This state describes a reference state of the press force, from which the actual required press force is set. This process is manual, complex, and requires considerable experience in its execution and interpretation of the results.
[0004] DE 103 23 041 B3 discloses a method for determining the bearer ring preload on a cylinder. The bearer ring preload is calculated based on the deflection of a cylinder journal. With the cylinder in the compression position against a second cylinder, a signal curve of signals from a strain gauge arranged on at least one journal of the cylinder is recorded as a function of the cylinder's angle of rotation over one full revolution of the cylinder. The bearer ring preload is calculated from the maximum of the signal curve and the angular displacement of the maximum compared to a calibration signal curve obtained from a calibration measurement, which also covers one full revolution.
[0005] DE 10 2010 042 991 A1 discloses a printing press module in which a strain gauge is arranged on a support and is attached via the support to a static support element of the printing press module, such as a module frame wall. The support is geometrically contoured such that it has at least one section that exhibits increased expansion or compression compared to the expansion or compression of the support element caused by the operation of a dynamic assembly mounted in the support element. The strain gauge is arranged on the support in the region of such a section with increased expansion or compression.
[0006] DE 10 2019 220 116 B3 shows a method for controlling bearer ring pressure in a printing unit. A strain sensor is used to determine the pressure between a first bearer ring of a first cylinder and a second bearer ring of a second cylinder, and an actuator is used to adjust one of the two bearer rings relative to the other. The strain sensor is used to measure the strain of a component such as the side wall of the frame of the printing unit in which the first cylinder and the second cylinder are mounted, in particular a side wall of the frame of the printing unit. In a first step, in a "print off" mode of the printing unit, first measured values are obtained, and in a second step, in a "print on" mode, second measured values are obtained. The bearer rings are in contact with one another in the "print on" mode and out of contact with one another in the "print off" mode.
[0007] The invention is based on the object of providing a method for checking and / or adjusting a bearer ring pressure in a measuring system and a measuring system.
[0008] The object is achieved according to the invention by the features of claim 1 and claim 16.

At least one first processing unit has at least one bearer ring of a first cylinder and at least one bearer ring of a second cylinder, which roll or are designed to roll off one another during a processing operation. During a measuring operation, at least one sensor in a measuring arrangement on the at least one first processing unit determines a set bearer ring pressure at at least one measuring point, preferably a second measuring point.

Particularly preferably, the second processing unit is constructed identically to the at least one first processing unit, at least with regard to the at least two cylinders having the bearer rings and / or a component supporting the cylinders. In a further measuring operation, the at least one sensor in the further measuring arrangement determines a set bearer ring pressure on the at least one second processing unit. At least one measured value determined in the further measuring arrangement on the at least one second processing unit is compared with at least one measured value determined in the measuring arrangement on the at least one first processing unit.

[0013] The at least one sensor is preferably arranged selectively on the at least one first processing unit or on the at least one second processing unit and / or selectively carries out the measuring operation or further measuring operation.
[0014] A measuring system comprising at least one first processing unit and at least one second processing unit is preferably provided.

The at least one sensor has the first measuring arrangement in a first measuring mode, the second measuring arrangement in a second measuring mode, and the third measuring arrangement in a third measuring mode.
[0015] By means of the method for checking and / or adjusting a bearer ring pressure in the measuring system and / or the measuring system created, the bearer ring pressure to be adjusted is advantageously set and / or checked without complex basic adjustment on at least two processing units. The setup time of the machine is advantageously shortened. A check of the adjusted bearer ring pressure is advantageously made possible regardless of the operating state of the machine.

The drive motor 92 preferably drives a, preferably closed, gear train. The drive system comprises, for example, the impression cylinders 34, the transfer drums 35, the blanket cylinders 33 and / or the inking units 42. In a first embodiment, the plate cylinders 32 are part of the drive system. Alternatively and in a preferred embodiment, however, the at least one plate cylinder 32 is mechanically separated from the drive system and preferably has a separate drive, preferably a single drive, with a drive motor 91.Individual functional units of the sheet-fed printing press, such as the substrate feed device 01, specifically the sheet feeder 01, the ink pickup roller 44 and / or the at least one dampening unit 51, and particularly preferably at least the at least one plate cylinder 32, are driven, for example, by separate drives, in particular individual drives, i.e. without a mechanical and / or positive drive connection to drives of the other functional units and the drive system comprising the main motor 92.

[0031] Preferably, at least one first cylinder 32, preferably designed as a forme cylinder 32, thus has its own first drive motor 91, in particular in order to be able to drive this first cylinder 32 or forme cylinder 32 independently of other rollers and / or cylinders 33, in particular independently of a second cylinder 33 or transfer cylinder 33 interacting with this first cylinder 32 or forme cylinder 32. Preferably, the second drive motor 92 assigned to the second cylinder 33 or transfer cylinder 33 is designed as a main motor 92 and / or is drive-connected to the gear train of the processing machine and / or is connected to the second cylinder 33 or transfer cylinder 33 via at least one gear train and / or at least one gear mechanism. Alternatively, the second cylinder 33, preferably designed as a transfer cylinder 33, also has a single drive with a drive motor 92, particularly preferably a direct drive.Advantageously, for example, relative movements between interacting forme cylinders 32 and impression cylinders 33 can be realized, which allow a particularly targeted different circumferential speed between forme cylinder 32 on the one hand and transfer cylinder 33 on the other hand.
[0032] A first drive motor 91 of the forme cylinder 32 preferably drives the forme cylinder 32 to rotate about its axis of rotation 93 and is thus designed as a rotary drive 91. A second drive motor 94 of the forme cylinder 32 preferably drives the forme cylinder 32 in the axial direction A, in particular parallel to its axis of rotation 93, and is thus designed as an axial drive 94, for example for lateral register adjustment. A first drive motor 92 of the transfer cylinder 33 preferably drives the transfer cylinder 33 to rotate about its axis of rotation 97 and is thus designed as a rotary drive 92. A second drive motor 96 of the transfer cylinder 33 preferably drives the transfer cylinder 33 in the axial direction A, in particular parallel to its axis of rotation 97, and is thus designed as an axial drive 96, for example for lateral register adjustment.
[0033] At least one inking unit 42 is provided for inking the printing form, which is preferably designed as a printing plate. The inking unit 42 is part of the printing unit superstructure 30. The inking unit 42 is designed, for example, as a short inking unit 42, as a ductor inking unit 42, as a film inking unit 42, or in another suitable manner.

For applying the ink or printing fluid prepared by the inking rollers 45 to the printing plate, at least two, preferably at least four, inking rollers 50 are provided.
[0034] In the direction of rotation 53 of the plate cylinder 32 during operation, a dampening forme roller 52 is optionally arranged upstream of the ink forme rollers 50.

A bridge roller 54, preferably switchable, can be provided between a first ink forme roller 50 in the direction of rotation 53 of the plate cylinder 32 and the dampening forme roller 52.

[0035] For example, the printing press comprises at least one turning device for turning the sheets that have already been partially printed and / or are to be printed. This is then preferably arranged between at least two of the printing units 05; 06. The turning device is preferably configured so that it can be switched from straight printing to perfecting printing, so that the press operates either in straight printing mode or in both straight and perfecting printing mode. Perfecting printing means that a sheet B is turned after being printed by a number of printing units 05; 06 in order to print its reverse side with the subsequent printing units 05; 06. The turning usually takes place according to the principle of trailing edge turning, for example by a three-drum turning device or a single-drum turning device.
[0036] Preferably, at least one processing unit 07 designed as a coating unit 07, also called a coating unit 07, is arranged downstream of the last printing unit 06.

The area of a coating unit superstructure of the coating unit 07, designed, for example, as a superstructure module, preferably differs from the printing unit superstructures 30 of the printing units 05; 06. Within the coating unit superstructure, there is preferably arranged a coating unit cylinder, preferably designed as a coating forme cylinder, on which a transfer means, preferably designed as a coating blanket or coating plate, is fastened, preferably clamped, via a fastening system, for example a clamping and / or tensioning system.To apply the varnish to the varnish blanket, which may be configured as a rubber blanket, or to the varnish plate, an application system is used, preferably designed as a chambered doctor blade system. This system preferably comprises an inking roller, in particular an anilox roller, with a cup structure on its outer surface, and a chambered doctor blade. The chambered doctor blade here contains two doctor blades that interact with the anilox roller.
[0037] Downstream of the last printing unit 05; 06 or, if at least one coating unit 07 is provided, after the coating unit 07, a drying section is preferably provided. To form the drying section, one or more drying devices are arranged in the printing substrate path between the last unit 05; 06; 07 designed as a printing or coating unit 05; 06; 07 and a product bundle preferably formed by at least one delivery stack. Preferably, one or more drying devices are arranged above and / or below the sheet path in the sheet delivery 08. In a preferred embodiment, the path between the last coating or printing unit 05; 06; 07 and the sheet delivery 08 can be extended, in particular by interposing a drying unit, in order to gain space for the arrangement of additional drying devices. If necessary, intermediate drying can also be carried out in the press by drying devices assigned to the cylinders.This intermediate drying is carried out, for example, additionally or alternatively by a drying unit arranged in the machine.
[0038] The sheet delivery 08 is preferably designed to have a delivery stack of products. For example, alternatively, the sheet delivery 08 is designed as a double-stack delivery or a multiple-stack delivery with at least two or more delivery stacks; in this case, at least one means acting as a diverter is preferably provided to deposit the processed sheet onto one of the stacks. The sheet delivery 08 preferably has a sheet conveying system arranged downstream of a sheet guiding system, preferably as a sheet guiding cylinder, specifically impression cylinder 34, which is preferably designed as a chain conveying system. The sheet conveying system preferably has traction means moved via drive and deflection means, which drive gripping devices for conveying the sheets. The gripping devices preferably have fixing elements for receiving and fixing the sheets. Clamping and / or suction grippers for gripping the sheet edges are preferably used as fixing elements.For example, additional gripping devices are provided for the trailing edges of the sheets.
[0039] The sheets are preferably removed individually from the feed stack of the substrate feed device 01, preferably the topmost sheet in each case, and preferably conveyed in an overlapping manner along the conveyor line 02 to the feed device 03. There, the separated sheet is aligned and transferred by the sheet acceleration means 04 to the first processing stage 05, preferably by means of at least one transfer drum. Within the first unit 05, preferably printing unit 05 or alternatively priming unit, the sheet is taken over by the printing cylinder 34 and transported through the printing nip, preferably being subjected to printing fluid, preferably ink or varnish. From the printing cylinder 34, the printed sheet is transferred to the downstream transfer drum 35 and from there transported to the next unit 06; 07, where a further processing step, preferably printing or varnishing, preferably takes place.After the final processing stage 05; 06; 07, the sheet is preferably transported to the sheet delivery 08, where it is preferably dried along the transport path. In the sheet delivery 08, the sheet is deposited on a delivery pile.
[0040] The processing units 05; 06; 07 have at least two cylinders 32; 33; 34 that roll on each other during processing. In particular, the forme cylinder 32 is designed to roll on the transfer cylinder 33. In addition, the transfer cylinder 33 is preferably designed to roll on the impression cylinder 34. The cylinders 32; 33; 34 that roll on each other thus form cylinder pairs.
[0041] For example, a first cylinder 32 of a cylinder pair is designed as a forme cylinder 32, preferably a plate cylinder 32. At least one printing forme, preferably a printing plate, can be mounted on it. The printing forme is preferably designed to be non-compressible. The second cylinder 33 of the cylinder pair is preferably formed by the transfer cylinder 33, which is preferably designed as a rubber cylinder 33, also called a blanket cylinder. The mountable blanket is preferably designed to be compressible. The at least one plate cylinder 32 and the at least one blanket cylinder 33 preferably each have at least one, in particular at least two, bearer rings 86; 87; 88; 89, which are attached to the end faces of the cylinders 32; 33. The cylinder 32 designated as the first cylinder 32, in particular the plate cylinder 32, has at least one first bearer ring 86 and at least one second bearer ring 87.The cylinder 33, in particular the blanket cylinder 33, referred to as the second cylinder 33, has at least one first bearer ring 88 and at least one second bearer ring 89. The bearer rings 86; 87; 88; 89 are preferably races made of preferably hardened steel and with high rolling resistance. If the blanket cylinder 33 and the plate cylinder 32 are prestressed against one another, the bearer rings 86; 87; 88; 89 of the cylinders 32; 33 preferably roll on one another. For example, the printing plates are mounted higher than the surface of the bearer rings 86; 87 of the plate cylinder 32. In a preferred embodiment, the printing plate is 0.15 mm above the bearer ring surface. In addition, in a preferred embodiment, the surface of the rubber blanket is also higher than the bearer ring surface, preferably 0.05 mm above it. Alternatively, for example, the surface of the rubber blanket is at the same height as the surface of the bearer rings 88; 89 of the rubber cylinder 33.
[0042] The at least one processing unit 05; 06; 07, for example the at least one printing unit 05; 06 and / or the at least one coating unit 07, thus has at least one bearer ring 86; 87, in particular a first and / or second bearer ring 86; 87, of a first cylinder 32 and at least one bearer ring 88; 89, in particular a first and / or second bearer ring 88; 89, of a second cylinder 33, which roll on one another and / or are designed to roll on one another and / or are designed to be unrollable during processing. In a particularly preferred embodiment, at least the at least one printing unit 05; 06 has the bearer rings 86; 87; 88; 89. For example, the at least one coating unit 07 is designed without bearer rings 86; 87; 88; 89, wherein then preferably instead of the bearer rings on the at least one coating unit 07, brass rings are arranged, which are not in contact with each other during operation.
[0043] The method for determining and / or adjusting and / or checking a bearer ring pressure is described below, particularly using the example of the first bearer rings 86; 88. Preferably, the method is carried out equally for the second bearer ring pair, i.e., the second bearer rings 87; 89. Thus, the method is preferably carried out on both sides for the at least one cylinder pair consisting of the first and second cylinders 32; 33.
[0044] There is preferably no bearer ring contact between the blanket cylinder 33 and the impression cylinder 34. The impression cylinder 34 preferably has measuring rings on both cylinder sides, the diameter of which is smaller than the bearer ring diameter. Preferably, the bearer rings 88; 89 of the blanket cylinder 33 do not touch the measuring rings of the impression cylinder 34. Alternatively, the impression cylinder 34 is also equipped with bearer rings, whereby when the cylinders 33; 34 are positioned against one another under pretension, bearer ring contact exists between the blanket cylinder 33 and the impression cylinder 34. The impression cylinder 34 and the blanket cylinder 33 then form a further cylinder pair consisting of a first and second cylinder 33; 34. The following method for determining and / or adjusting and / or checking a bearer ring pressure is then preferably also carried out for the at least one, preferably both, bearer ring pairs of this cylinder pair.
[0045] In the coating unit 07, the cylinder pair is preferably formed by the printing cylinder and the coating forme cylinder, which particularly preferably also each have first and second bearer rings. The following method for determining and / or adjusting and / or checking a bearer ring pressure is then preferably also carried out for at least one, preferably both, bearer ring pairs of this cylinder pair.
[0046] The at least one first cylinder 32 and the at least one second cylinder 33 are mounted in a component, preferably a housing or frame of the processing unit 05; 06; 07. This is preferably the housing of the superstructure module 30; in the case of the pressure cylinder 34, the housing of the substructure module 31. The cylinders 32; 33; 34 are preferably mounted on both sides in cylinder bearings 104. The at least one cylinder bearing 104 is preferably designed as an eccentric bearing bush.
[0047] To set a required bearer ring pressure Mp, the processing unit 05; 06; 07 has at least one actuator 98; 99; 101; 102. Preferably, at least one actuator 98; 99 is assigned to the first cylinder 32. Preferably, additionally or alternatively, at least one actuator 101; 102 is assigned to the second cylinder 33. Particularly preferably, an actuator 98; 99; 101; 102 is assigned to each side of the at least one cylinder 32; 33. The at least one actuator 98; 99; 101; 102 is particularly preferably designed as a spindle drive. Preferably, the at least one actuator 98; 99; 101; 102 has a motor. For example, alternatively or additionally, the at least one actuator 98; 99; 101; 102 can be operated manually.The at least one actuator 98; 99; 101; 102 preferably acts on the at least one cylinder bearing 104, wherein, in a particularly preferred embodiment, the eccentric bearing bushes are adjustable or are adjusted by means of the actuator 98; 99; 101; 102. For example, the rotation axes 93; 97 of the cylinders 32; 33 are adjusted relative to one another by the at least one actuator 98; 99; 101; 102.
[0048] Preferably, at least one stop is provided which defines a positioning of the bearer rings 86; 88; 87; 89 relative to one another with a set bearer ring pressure Mp. Preferably, the at least one stop defines an adjustment range of the at least one actuator 98; 99; 101; 102, in particular of the at least one spindle drive. The maximum permissible pressure is preferably present at at least one stop. The maximum permissible pressure is preferably the required bearer ring pressure Mp. Depending on the result of the at least one computing unit, the at least one stop has a first position or a second position, or a further position different therefrom. It is adjusted by positioning it in one of the positions such that when the bearer rings 86; 88; 87; 89 are positioned against one another during machining, they have the required bearer ring pressure Mp.At least one stop is preferably set manually into the relevant position.
[0049] The machining unit 05; 06; 07 has at least one measuring point 81; 82 for determining at least one measured variable Y characterizing a bearer ring pressure Mp to be set. Preferably, at least one measuring point 81; 82 of the measuring points 81; 82, preferably at least a first measuring point 81 and at least a second measuring point 82, is arranged on at least one component supporting the first cylinder 32 and the second cylinder 33, preferably the housing of the superstructure module 30. The resulting radial forces of a bearer ring contact are preferably transferred into the housing and lead to measurable frame deformations. Thus, by measuring the frame deformations, conclusions can be drawn about the forces present in the bearer ring contact.The at least one measuring point 81; 82 is a position at which the frame expansion reacts to the force between the cylinders 32; 33 rolling against one another, i.e., the set bearer ring pressure; i.e., a position whose frame expansion can be influenced by the pressing force and thus advantageously a change can be measured. For example, a top or bottom side of the frame is therefore unsuitable, whereas the side walls of the frame, in particular on their inside and / or outside, offer suitable measuring points 81; 82. For example, alternatively, the at least one measuring point is arranged on a cylinder bearing 104 of the first and / or second cylinder 32; 33. However, this has the disadvantage that a sensor is difficult to position and cannot be quickly and easily assembled and disassembled.
[0050] For example, the at least one measuring point 81; 82 each describes an area within which the respective measurement is or can be taken by the at least one sensor. Preferably, the area of the at least one measuring point 81; 82 is larger than the area actually required by the sensor for measurement, preferably by at least 3 mm (millimeters), preferably at least 5 mm, more preferably at least 10 mm. For example, in addition, the area is larger than the area actually required by the sensor for measurement by a maximum of 25 mm, preferably a maximum of 15 mm, more preferably a maximum of 12 mm, particularly preferably a maximum of 10 mm.For example, two different, identical processing units 05; 06; 07 have corresponding measuring points 81; 82, wherein the actual measuring position of the sensor within the measuring points deviates from one another by a maximum tolerance value, for example by a maximum of 10 mm (millimeters), more preferably a maximum of 5 mm, more preferably a maximum of 2 mm, more preferably a maximum of 1 mm, more preferably a maximum of 0.5 mm, more preferably a maximum of 0.3 mm, more preferably a maximum of 0.1 mm. The deviation is attributable, for example, to manufacturing inaccuracies.
[0051] Preferably, at least one measuring point 81, designated as the first measuring point 81, is provided. A basic adjustment of the bearer ring pressure Mp during pressure assembly preferably takes place using the at least one first measuring point 81. The at least one first measuring point 81 is, for example, a measuring point 81 that is not accessible to the operator during machining. The at least one first measuring point 81 is preferably a position on a side of the component facing the cylinders 32; 33, preferably a position on the side of the component facing the cylinders 32; 33 that is horizontally offset from a connecting path between the rotation axes 93; 97 of the mounted cylinders 32; 33. Preferably, the at least one first measuring point 81 is horizontally offset from the connecting path between the rotation axes 93; 97 of the mounted cylinders 32; 33 with respect to the side of the component having the at least one first measuring point 81.At the at least one first measuring point 81, the deformations of the component due to the bearer ring pressing are preferably particularly high relative to other positions on the component, which enables a simple and accurate measurement.
[0052] Preferably, at least one measuring point 82, referred to as the second measuring point 82, is provided. For example, the at least one second measuring point 82 is used to determine and / or check and / or fine-tune the set bearer ring pressure Mp, preferably during printing tower assembly. Additionally or alternatively, a measurement of the set bearer ring pressure Mp is performed using the at least one second measuring point 82 during a machining operation of the machining unit 05; 06; 07. The at least one second measuring point 82 is preferably at a greater distance from the connecting section between the rotation axes 93; 97 of the mounted cylinders 32; 33 than the at least one first measuring point 81.Additionally or alternatively, the at least one second measuring point 82 is preferably a position on a side of the component different from the side facing the cylinders 32; 33, for example the outside of the processing unit 05; 06; 07. The outside is preferably the side of the frame facing away from the mounted cylinders 32; 33, preferably with the normal vector of the side being parallel to the rotation axis 93; 97. In particular, the second measuring point 82 must also be a position at which the frame expansion reacts to the bearer ring pressure Mp and thus advantageously a change can be measured.
[0053] The at least one measuring point 82, preferably second measuring point 82, is preferably arranged such that during a machining operation the at least one sensor is adjusted or can be adjusted from a measuring arrangement, in particular a second measuring arrangement of the sensor, on the at least one first machining unit 05; 06; 07 for determining the measured variable Y at its measuring point 82, to a different measuring arrangement, in particular a third measuring arrangement of the sensor, on the at least one second machining unit 05; 06; 07 for determining the measured variable Y at its measuring point 82. In particular, the sensor is thus adjusted or can be adjusted accordingly during operation from an orientation on or at the at least one measuring point 82 of the at least one first machining unit 05; 06; 07 to an orientation on or at the at least one measuring point of the at least one second machining unit 05; 06; 07.Thus, no machine stop is necessary to adjust the sensor. Simple and quick checking and adjustment of the bearer ring pressure is possible, regardless of machine operation. Particularly preferably, the at least one second measuring point 82 is a position accessible to an operator during operation of the processing unit 05; 06; 07. Thus, preferably, the at least one measuring point 82 in the at least one second measuring arrangement and / or in the at least one third measuring arrangement is a position accessible to an operator during operation of the processing units 05; 06; 07. Accessible here preferably describes that an operator can attach and remove the at least one sensor to the at least one measuring point during operation of the machine.
[0054] At least one sensor is provided for determining the at least one measured variable Y at the at least one measuring point 81; 82. Sensors are preferably provided on both sides of the cylinders 32; 33, i.e. at least a first sensor in the axial direction A before and at least one further sensor in the axial direction A after the cylinders 32; 33. Thus, the bearer ring pressures Mp to be set are preferably determined on both sides. The at least one sensor preferably determines at least one variable correlated with an expansion of a component, preferably a deformation. Preferably, the deformation of a frame wall is measured. The at least one sensor is preferably an expansion sensor and particularly preferably an extensometer. An extensometer is a strain measuring device used to measure the expansion of a material under load. Preferably, the extensometer is a strain transformer with or without an amplifier.
[0055] In a preferred embodiment, the at least one sensor is mounted in direct contact with a measuring point 81; 82 of the measuring points 81; 82, preferably fastened thereto, particularly preferably screwed. As a contact sensor, the extensometer preferably has sensor transducers or clip-on transducers. The deformation or expansion of the component is preferably transmitted to the sensor by frictional engagement. The at least one sensor is preferably arranged directly on the component, i.e. preferably without any means in between that amplifies the measured variable Y, and is detachable. The direct arrangement increases the measuring accuracy. The detachable design increases the flexibility of the arrangement and assembly of the sensor.The component supporting the cylinders 32; 33 preferably has connecting devices, for example thread-like elements, preferably threads, at the at least one measuring point 81; 82, which come into operative contact with connecting elements, preferably screws, of the at least one sensor during its arrangement at the respective measuring point 81; 82.
[0056] In an alternative embodiment, the at least one sensor is designed as a non-contact sensor, i.e., it is preferably neither in direct nor indirect contact with the measuring point 81; 82. The sensor is then arranged such that the at least one measuring point 81; 82, at which it is intended to detect the measured variable Y at this time, is within its detection range. As a non-contact sensor, the at least one sensor is preferably laser-based or camera-based, i.e., preferably an optical sensor. The non-contact design of the sensor has the advantage of particularly simple and flexible positioning of the sensor.
[0057] The measured variable Y preferably characterizes the bearer ring pressure present at the time of the measurement. In particular, a different measured value y1; y2; yp of the measured variable Y is achieved depending on the bearer ring pressure occurring. The measured variable Y is preferably a variable correlating with an elongation of a component, in particular the deformation of the frame supporting the cylinders 32; 33. For example, with a non-contact sensor, a changing distance between two measuring points is determined, which corresponds to the occurring elongation. For example, with a sensor in contact, a voltage is measured that is generated in the extensometer by the occurring deformation, for example by means of a built-in strain gauge.
[0058] At least one computing unit is preferably connected to the at least one sensor via data technology. The sensor transmits its measurement data to the at least one computing unit, which then processes it further. The at least one computing unit is preferably designed to calculate at least one setting value dx2. At least one control unit that is connected to the computing unit via data technology is preferably designed to control and / or regulate at least one actuator 98; 99; 101; 102 for the relative adjustment of the bearer rings 86; 87; 88; 89 to one another. At least one display unit for displaying a result of a calculation by the at least one computing unit is preferably connected to the at least one computing unit and more preferably displays at least the result of the calculation.For example, the result of the calculation is transmitted to a control unit and / or the operator reads the result.
[0059] In the foregoing and in the following, the bearer ring pressure preferably describes the radial forces of the bearer rings 86; 87; 88; 89 which they act on each other. For example, the pressure is described indirectly via a relative adjustment path of the bearer rings 86; 87; 88; 89 or the cylinders 32; 33 to each other. After assembly of the cylinders 32; 33 and their bearer rings 86; 87; 88; 89 in the supporting component, the cylinders 32; 33 are spaced apart from each other. There is no contact between the cylinders 32; 33 and / or their bearer rings 86; 87; 88; 89. By relative adjustment of the rotation axes 93; 97 of the cylinders 32; 33 or the bearer rings 86; 87; 88; 89, contact is created, which is accompanied by an effective pressing force. From the initial contact of the bearer rings 86; 87; 88; 89 with each other, the pressure is further increased with further relative adjustment toward each other.After further relative adjustment towards each other, a linear relationship results between the existing pressure and the resulting sensor signal during a measurement.
[0060] During printing tower assembly, a basic adjustment, i.e., preferably the initial adjustment, of the bearer ring pressure Mp is preferably carried out. This adjusted bearer ring pressure Mp is then achieved during machining when the bearer rings 86; 87; 88; 89 are brought into contact with one another. The bearer ring pressure Mp to be adjusted is preferably a previously defined value that provides an optimum balance between wear and print image quality. For example, the bearer ring pressure Mp to be adjusted corresponds to a relative adjustment path X of the bearer rings 86; 87; 88; 89 towards one another of 0.1 mm (millimeters) from contact. However, due to the non-linear relationship during pressure build-up, the actual first contact is difficult to determine from the sensor signal, which is why measured values y1, y2 of the linear range are particularly preferably used to determine the bearer ring pressure Mp to be adjusted.
[0061] In one method, the bearer ring pressure Mp of the processing unit 05; 06; 07 to be adjusted is determined and / or adjusted. The method for determining and / or adjusting the bearer ring pressure Mp of the processing unit 05; 06; 07 advantageously enables precise adjustment, in particular with regard to a first adjustment of the bearer ring pressure during assembly, based on measured values y1; y2; yp. The measurement results are advantageously easily reproducible, and the adjustment is easy to repeat and document. The method is simple to carry out and advantageously enables objective adjustment regardless of the operator's experience. The method is advantageously suitable as a calibration method for calibrating the at least one sensor, in particular when it is designed as an extensometer.
[0062] The determination and / or adjustment of the bearer ring pressure Mp to be adjusted is preferably carried out during the assembly of the cylinders 32; 33, preferably during the printing tower assembly, and / or before the start of the machining operation of the machining unit 05; 06; 07.
[0063] The at least one sensor is preferably attached to the processing unit 05; 06; 07 in a first step such that it detects the at least one measuring point 81; 82, preferably the first measuring point 81, with its detection range. The arrangement of the at least one sensor for detecting the first measuring point 81 preferably describes a first measuring arrangement of the sensor. In a first measuring operation, the at least one sensor determines at least one measured value y1; y2; yp at the at least one first measuring point 81. The at least one sensor is preferably attached in direct contact with the measuring point 81; 82 or determines the measured values y1; y2; yp at the measuring point 81; 82 without contact. For example, in the case of a contactless design, the optical detection unit of the sensor is aligned with the at least one measuring point 81; 82.In the alternative embodiment with contact, the at least one sensor is preferably mounted, preferably screwed, at the at least one measuring point 81; 82. Preferably, at least one sensor is attached on each side, i.e., at a measuring point 81; 82 in axial direction A before and at a measuring point 81; 82 in axial direction A after the cylinders 32; 33.
[0064] Before determining at least one measured value y1; y2, in particular at least one first measured value y1 and / or at least one second measured value y2, a lateral surface of the at least one bearer ring 86; 87; 88; 89 of the bearer rings 86; 87; 88; 89, preferably of all bearer rings 86; 87; 88; 89, is preferably cleaned. This advantageously increases the measurement accuracy.
[0065] Before determining at least one measured value y1; y2, in particular the at least one first measured value y1 and / or the at least one second measured value y2, at least one printing forme, preferably a printing plate, is preferably removed from at least one of the cylinders 32; 33. Alternatively, the measurement is carried out before the at least one printing forme is mounted. In particular, in the preferred embodiment, the at least one cylinder 32, which is preferably designed as a forme cylinder 32, is free of printing forms during the determination of the at least one measured value y1; y2, in particular the at least one first measured value y1 and / or the at least one second measured value y2. Thus, the at least one forme cylinder 32 is preferably free of printing forms when the at least one sensor is in a state that determines the measured values y1; y2.For example, the surface of the at least one printing forme, when arranged on the at least one cylinder 32, protrudes further than the surface of the at least one bearer ring 86; 87. When the printing forme is removed from the forme cylinder 32, the forme cylinder 32 and transfer cylinder 33 preferably roll onto one another exclusively via their bearer rings 86; 87; 88; 89. By measuring with the printing forme removed, their influence on the measurement is advantageously excluded and only the influence of the bearer ring contact is measured. Alternatively, the measurement is carried out with the printing forme mounted, in which case its influence is preferably taken into account. For example, the at least one rubber blanket is also removed, although this is optional due to the compressible design.
[0066] Preferably, the cylinders 32; 33 are rotated relative to each other so that their cylinder channels are outside of a possible contact area. This eliminates the influence of the cylinder channel on the measurement.
[0067] When the bearer rings 86; 87; 88; 89 are arranged outside of contact with one another, a zero adjustment of the at least one sensor is preferably carried out. A zero adjustment preferably means that the determined measured value is defined as zero for the now available setting parameters. The zero adjustment preferably takes place before a first measurement of the sensor, preferably before the determination of the at least one first measured value y1. Alternatively, the zero adjustment takes place after the first measurement and / or after the measurement of the at least one second measured value y2. It is crucial that the zero adjustment preferably takes place before a calculation of a straight line equation.
[0068] The rolling bearer rings 86; 87; 88; 89 are preferably positioned against each other, i.e., in contact with each other. This positioning forms a starting position for determining the bearer ring pressure Mp to be set and / or the relative adjustment of the bearer rings 86; 87; 88; 89 to each other.
[0069] For example, to adjust the bearer rings 86; 87; 88; 89 relative to one another, only one actuator 98; 99; 101; 102 is actuated, or the two actuators 98; 99; 101; 102 of one of the cylinders 32; 33 are actuated. Alternatively, actuators 98; 99; 101; 102 of both cylinders 32; 33 are actuated. Preferably, the at least one actuator 98; 99; 101; 102 is controlled by a control unit that actuates its motor. Alternatively, manual actuation is possible.
[0070] At least one measuring state M1; M2 is assumed, in which at least one measured value y1; y2 of a measured variable Y is determined. In particular, at least two measuring states M1; M2 are assumed one after the other, in each of which at least one measured value y1; y2 is determined. During the determination of the at least one measured value y1; y2, preferably the at least one first measured value y1 and the at least one second measured value y2, the cylinders 32; 33 are preferably stationary with respect to a movement about their axes of rotation 93; 97, i.e. they do not rotate. Advantageously, a high level of measurement accuracy is achieved. The measured variable Y is preferably determined at the at least one measuring point 81; 82, which is a position on the component, preferably the frame, supporting the cylinders 32; 33.Particularly preferably, the at least one measuring point 81; 82 is horizontally offset with respect to the side of the component having the measuring point 81; 82 relative to the connecting path between the rotation axes 93; 97 of the mounted cylinders 32; 33.
[0071] Preferably, starting from the starting position, the bearer rings 86; 87; 88; 89, i.e. in particular the two bearer rings 86; 87; 88; 89 rolling on one another, are arranged in touching contact with one another in a first measuring state M1 by means of the at least one actuator 98; 99; 101; 102 by relative adjustment of the bearer rings 86; 87; 88; 89 to one another while applying a first pressing force. Preferably, the distance between the rotation axes 93; 97 of the cylinders 32; 33 is smaller in the first measuring state M1 than in the starting position. For example, the bearer rings 86; 87; 88; 89 were adjusted towards one another relative to one another by at least 0.01 mm (zero point zero one millimeter), preferably at least 0.03 mm, and / or a maximum of 0.08 mm, preferably a maximum of 0.05 mm.Preferably, the relative adjustment starting from the starting positioning in the first measuring state M1 ensures that the measured values y1 determined here lie in a measuring range with a linear relationship between the sensor signal and the resulting pressing force.
[0072] In the first measurement state M1, at least one first measured value y1 of a measured variable Y is determined by the at least one sensor. For example, at least two, preferably at least five, individual measured values are determined in the first measurement state M1, and their mean value is calculated. The mean value then preferably describes the determined first measured value y1. Preferably, the at least one determined first measured value y1 is stored in at least one data set. Preferably, the at least one computing unit accesses the at least one data set.
[0073] The relative adjustment path X describes, for example, the change in the distance between the rotational axis 93 of the first cylinder 93 and the rotational axis 97 of the second cylinder 33. The relative adjustment path X preferably characterizes the pressure of the bearer rings 86; 87; 88; 89 present at the respective time and state. In the first measuring state M1, a first control value x1 is present. A first adjustment path dx1 preferably describes the length of the adjustment path X covered by which the bearer rings 86; 87; 88; 89 were moved towards one another relative to one another, starting from a first touch contact up to the first measuring state M1, i.e. up to the first control value x1. Neither the absolute value of the first control value x1 nor the absolute value of the first adjustment path dx1 are preferably known at the time of the first measurement in the first measuring state M1.
[0074] Preferably, starting from the first measuring state M1, the bearer rings 86; 87; 88; 89, i.e. in particular the two bearer rings 86; 87; 88; 89 rolling on one another, are arranged in touching contact with one another in a second measuring state M2 by means of the at least one actuator 98; 99; 101; 102 by relative adjustment of the bearer rings 86; 87; 88; 89 to one another, while applying a second pressing force. Thus, between the first and second measuring states M1; M2, preferably at least one of the bearer rings 86; 87; 88; 89 rolling on one another is adjusted in its positioning relative to the second bearer ring 86; 87; 88; 89 of the bearer rings 86; 87; 88; 89 rolling on one another. The second pressing force is different from the first pressing force, preferably higher. Preferably, the distance between the rotation axes 93; 97 of the cylinders 32; 33 is smaller in the second measuring state M2 than in the first measuring state M1.
[0075] For example, in order to avoid premature wear due to excessive pressing force, the first measuring state M1 and the second measuring state M2 are selected by adjusting the bearer rings 86; 87; 88; 89 relative to one another so that the first pressing force and the second pressing force are greater than zero and smaller than the pressing force to be set for the bearer ring pressure Mp to be determined.
[0076] In the second measuring state M2, at least one second measured value y2 of the measured variable Y is determined by the at least one sensor. For example, at least two, preferably at least five, individual measured values are determined in the second measuring state M2, and the mean value is calculated. The mean value then preferably describes the determined second measured value y2. The measured values y2 determined here preferably lie in the measuring range with a linear relationship between the sensor signal and the resulting pressing force. The at least one determined second measured value y2 is preferably stored in at least one data set. The at least one computing unit preferably accesses the at least one data set.
[0077] In the second measuring state M2, a second control value x2 is present. To set the second measuring state M2, the relative position of the bearer rings 86; 87; 88; 89 to one another is changed by a specified distance, starting from the relative position in the first measuring state M1. The distance describes a relative adjustment of the bearer rings 86; 87; 88; 89 by the length of the travel dx0. For example, the travel dx0 corresponds to one complete revolution of the spindle drive. For example, the travel dx0 is 0.05 mm. The absolute value of the control value x2 corresponds to the sum of x1 and dx0.
[0078] The at least one first measured value y1 and the at least one second measured value y2 are preferably transmitted from the at least one sensor to at least one computing unit. For example, the at least one display unit displays the at least two measured values y1; y2.
[0079] The at least one computing unit preferably calculates a setting value dx2, taking into account the at least one first measured value y1 and the at least one second measured value y2, in order to achieve the bearer ring pressure Mp to be set. In particular, a setting value is calculated that uniquely characterizes the bearer ring pressure Mp to be set. The calculation of the at least one setting value dx2 preferably comprises several calculation steps, of which at least one calculation step is preferably carried out by the at least one computing unit. For example, at least two, for example even all, of the subsequent calculation steps are carried out in a common calculation process and / or summarized in a common equation.
[0080] As the setting value dx2, a travel dx2 of one of the bearer rings 86; 87; 88; 89 relative to the second of the bearer rings 86; 87; 88; 89 is preferably calculated. The setting value dx2 particularly preferably describes the travel dx2 starting from the second measuring state M2 until the setting value xp of the bearer ring pressure Mp to be set is achieved. For example, the setting value dx2 is the difference between the travels dx0 and dx1 and the setting value xp when the bearer ring pressure Mp is set. For example, alternatively, a travel starting from the zero point or the first measuring state M1 is calculated as the setting value.
[0081] Preferably, in addition to or as an alternative to the travel distance dx2, at least one variable correlating with the travel distance dx2 is calculated as a setting value or further setting value, for example the necessary number of revolutions of the spindle drive and / or control parameters of the motor of the at least one actuator 98; 99; 101; 102.
[0082] Preferably, additionally or alternatively, the measurement signal yp of the measured variable Y to be generated is calculated when the desired bearer ring pressure Mp is reached, or a value that clearly characterizes it is calculated. For example, this allows for a verification of the set bearer ring pressure Mp.
[0083] One of the calculation steps taken into account or a part of the calculation is preferably the determination of a straight line equation. Taking into account the at least two measured values y1 and y2, a straight line equation is preferably calculated, preferably by means of the at least one computing unit. This straight line preferably runs through the zero point of the axis with the relative adjustment path X plotted. The bearer rings 86; 87; 88; 89 are preferably arranged relative to one another in the first measuring state M1 and in the second measuring state M2 such that the at least one first measured value y1 and the at least one second measured value y2 form a linear relationship with a zero point of the axis with the relative adjustment path X plotted. For example, a diagram is generated in the at least one computing unit from which the bearer ring pressure Mp to be set can be read off.
[0084] For example, additionally or alternatively, as part of the calculation, the actual zero point, i.e., the positioning at the first contact of the bearer rings 86; 87; 88; 89 rolling against each other, is calculated together, taking into account at least two measured values y1 and y2. This results, in particular, from the determined linear equation.
[0085] Preferably additionally or alternatively, as part of the calculation, the travel dx1 is calculated taking into account the at least two measured values y1 and y2 in order to set the first measuring state M1 by relative adjustment starting from the first contact of the bearer rings 86; 87; 88; 89 with each other.
[0086] Preferably, the measurements are performed on both sides by at least one sensor each. This means that measurements are performed for both the first bearer rings 86; 88 and the second bearer rings 87; 89. In particular, a first sensor performs the measurements for the first bearer rings 86; 88, while another sensor performs the measurements for the second bearer rings 87; 89. Preferably, at least one setting value dx2 is calculated for each of the sides. For example, based on the first setting value of the first side, i.e., axially in front of the cylinder 32; 33, at least one first actuator 98; 101 is actuated, whereas based on the second setting value of the second side, i.e., axially after the cylinder 32; 33, at least one second actuator 99; 102 is actuated.
[0087] After the calculation has been completed, the at least one bearer ring 86; 87 of the first cylinder 32 and the at least one bearer ring 88; 89 of the second cylinder 33 are preferably adjusted relative to one another by the at least one actuator 98; 99; 101; 102 according to the calculated setting value dx2. As a result, they are arranged in the bearer ring pressure Mp to be set. In particular, the bearer rings 86; 87; 88; 89 are adjusted relative to one another by the adjustment distance dx2 starting from the second measurement state M2. For example, the set positioning is checked by determining at least one measured value yp, for example also an average value from several measured values. Preferably, the positioning of the bearer rings 86; 87; 88; 89 relative to one another with the bearer ring pressure Mp set is marked and / or fixed by setting the at least one stop.At least one stop is positioned according to the adjusted bearer rings 86; 87; 88; 89.
[0088] The at least one sensor is preferably removed, preferably disassembled, from the machining unit 05; 06; 07 before machining operation of the machining unit 05; 06; 07 after the measurements have been taken. This advantageously frees up the installation space for the machining process and / or prevents it from being obstructed by the sensor. Furthermore, the sensor is protected from damage during machining.
[0089] For machining, disassembled printing forms are preferably mounted on the at least one form cylinder 32. During machining, when the cylinders 32; 33 are adjusted, the bearer rings 86; 87; 88; 89 are arranged against one another such that they have the bearer ring pressure Mp to be set, for example, determined by the at least one stop.
[0090] A measuring system has the at least one processing unit 05; 06; 07 as at least a first processing unit 05; 06; 07. The measuring system additionally has at least one second processing unit 05; 06; 07. The at least one first and / or second processing unit 05; 06; 07 each have the at least one bearer ring 86; 87 of the first cylinder 32 and the at least one bearer ring 88; 89 of the second cylinder 33, which are designed to roll or can roll on one another during a processing operation. The term “first processing unit” here preferably describes a processing unit 05; 06; 07 on which a first or second measuring operation is carried out. This is, for example, the first processing unit 05 arranged in the machine according to a transport of substrate or also a further processing unit 06; 07 arranged second or third or later according to the transport of substrate. 07.For example, alternatively, the first processing unit is a processing unit that is arranged outside the machine, for example a processing unit of another machine or a test bench. The at least one second processing unit 05; 06; 07 is preferably structurally identical to the at least one first processing unit 05; 06; 07, at least with regard to the at least two cylinders 32; 33 having the bearer rings 86; 87; 88; 89 and / or with regard to the component supporting the cylinders 32; 33. The at least one processing unit 05; 06; 07, preferably the at least one first and / or second processing unit 05; 06; 07, has the at least one measuring point 81; 82.In particular, the at least one first and / or second processing unit 05; 06; 07 has the at least one first measuring point 81 and the at least one second measuring point 82, which are arranged on the at least one component supporting the first cylinder 32 and the second cylinder 33.
[0091] The measuring system comprises at least one sensor, in particular a strain sensor, preferably an extensometer. The at least one sensor determines the existing bearer ring pressure. Once the bearer ring pressure Mp to be set has been set, the at least one sensor determines the at least one measured value yp of the measured variable Y that characterizes the set bearer ring pressure Mp.
[0092] The at least one sensor is preferably arranged or can be arranged optionally in a first measuring arrangement for determining the at least one measured variable Y at the at least one first measuring point 81 of the at least one first processing unit 05; 06; 07, in a second measuring arrangement for determining the at least one measured variable Y at the at least one second measuring point 82 of the at least one first processing unit 05; 06; 07 or in a third measuring arrangement for determining the at least one measured variable Y at at least one measuring point 82, preferably second measuring point 82, of the at least one second processing unit 05; 06; 07. It is therefore adjustable between the measuring arrangements. The at least one sensor is therefore configured such that it determines the at least one measured variable Y at the at least one first measuring point 81 in a first measuring arrangement.In addition, the at least one sensor is configured such that, in a second measuring arrangement, it determines the at least one measured variable Y at the at least one second measuring point 82. The at least one sensor is additionally configured such that, in a third measuring arrangement, it determines the at least one measured variable Y at the at least one measuring point 82, preferably the measuring point 82 configured as the second measuring point 82, of the at least one second processing unit 05; 06; 07.
[0093] The at least one measuring point 82 of the third measuring arrangement on the at least one second processing unit 05; 06; 07 preferably corresponds to the at least one second measuring point 82 of the second measuring arrangement on the at least one first processing unit 05; 06; 07 with regard to its position. For example, two different, identical processing units 05; 06; 07 thus have corresponding measuring points 81; 82, wherein the actual measuring position of the sensor within the measuring points deviates from one another by a maximum tolerance value, for example by a maximum of 20 mm (millimeters), preferably a maximum of 10 mm, more preferably a maximum of 5 mm, more preferably a maximum of 2 mm, more preferably a maximum of 1 mm. In particular, the measured values y1; y2; yp obtained at the corresponding, preferably second, measuring points 82 of the various processing units 05; 06; 07 are comparable with one another.
[0094] The at least one sensor preferably has the first measuring arrangement in a first measuring operation, the second measuring arrangement in a second measuring operation, and / or the third measuring arrangement in a third measuring operation. The at least one sensor preferably has either the first measuring arrangement or the second measuring arrangement or the third measuring arrangement. Thus, the sensor is preferably designed such that it can switch between the at least two, preferably three, measuring points 81; 82. Advantageously, the flexibility of the measurement is increased by selecting the appropriate measuring point 81; 82. Particularly preferably, the at least one sensor is adjustable at least between the second and third measuring arrangements during a machining operation.
[0095] The at least one computing unit, which is data-linked to the at least one sensor, is preferably configured to compare at least two measured values from at least two measuring arrangements, preferably from the second and third measuring arrangements.

At least one display unit for displaying at least two measured values y1; y2; yp determined in the measuring arrangements and / or for displaying a comparison of at least two measured values y1; y2; yp determined in the measuring arrangements is preferably connected in terms of data technology to the at least one sensor and / or to the at least one computing unit performing the comparison.
[0096] The bearer ring pressure is checked and / or adjusted in the measuring system. In particular, a bearer ring pressure is determined on the at least one first processing unit 05; 06; 07 serving as a reference and is checked and / or adjusted accordingly on the at least one second processing unit 05; 06; 07. Advantageously, the bearer ring pressure Mp to be adjusted is set and / or checked on at least two processing units 05; 06; 07 without complex basic adjustment, preferably independently of the operating state of the machine. Advantageously, the machine setup time is shortened. Advantageously, a simple and quick method for calibrating the at least one sensor, in particular when it is designed as an extensometer, is achieved.Advantageously, a simple calibration of at least one measuring point 82 of the second processing unit 05; 06; 07 is achieved by comparison with the measuring point 82 on the at least one first processing unit 05; 06; 07 serving as a reference.
[0097] In the at least one first machining unit 05; 06; 07, the bearer ring pressure is or will preferably be adjusted so that the bearer rings 86; 87; 88; 89, in particular the at least two bearer rings 86; 87; 88; 89 rolling on one another, have the bearer ring pressure Mp to be adjusted during machining when the cylinders 32; 33 are positioned against one another. In particular, the bearer rings 86; 87; 88; 89 rolling on one another have the pressing force according to the adjusted bearer ring pressure Mp. The bearer ring pressure Mp to be adjusted is preferably determined and / or adjusted in a first measuring operation on the at least one first machining unit 05; 06; 07.Particularly preferably, in the first measuring operation, the at least one sensor or a further sensor, which is preferably identical in construction to the at least one sensor, in the first measuring arrangement at the at least one first measuring point 81 on the at least one first processing unit 05; 06; 07 determines the at least one measured value y1; y2 for setting the bearer ring pressure Mp to be set.
[0098] The bearer ring pressure Mp to be set or set is preferably set according to the above method for determining and / or setting the bearer ring pressure Mp to be set of the machining unit 05; 06; 07. In particular, the bearer ring pressure Mp to be set or set, preferably the one present in machining operation, is set in that at the at least one first measuring point 81 of the first measuring arrangement of the at least one first machining unit 05; 06;07 the at least one first measured value y1 of the measured variable Y is determined by applying the first pressing force and the at least one second measured value y2 of the measured variable Y is determined by applying the second pressing force, that the at least one setting value dx2 for achieving the bearer ring pressure Mp to be set is calculated taking into account the at least one first measured value y1 and the at least one second measured value y2, and preferably that the at least one bearer ring 86; 87 of the first cylinder 32 and the at least one bearer ring 88; 89 of the second cylinder 33 are adjusted relative to one another by the at least one actuator 98; 99; 101; 102 in accordance with the calculated at least one setting value dx2.;
[0099] In a measuring operation, in particular in the second measuring operation, the at least one sensor in a measuring arrangement, preferably in the second measuring arrangement, on the at least one first processing unit 05; 06; 07 at at least one measuring point 82, preferably the at least one second measuring point 82, determines the set bearer ring pressure Mp, preferably its measured value yp of the measured variable, which uniquely characterizes the set bearer ring pressure Mp. For example, at least two, preferably at least five, individual measured values are determined, the mean of which is calculated. The mean value then preferably describes the determined measured value yp. Preferably, the at least one determined measured value yp is stored in at least one data set. Preferably, the at least one computing unit accesses the at least one data set.
[0100] Preferably, the at least one sensor of the second measuring mode is the same sensor as in the first measuring mode. Alternatively, for example, a different sensor is used, which is then preferably of the same type as the sensor of the first measuring mode.
[0101] Advantageously, the setting is checked easily and quickly by changing the measuring arrangement compared to the first measuring operation. For example, the set bearer ring pressure Mp is checked by arranging the at least one sensor or at least one further sensor in the at least one second measuring arrangement, i.e. by determining the measured variable Y at the at least one second measuring point 82. Preferably before or alternatively after determining the at least one measured value yp of the set bearer ring pressure Mp at the at least one second measuring point 82 of the at least one first processing unit 05; 06; 07, the linearity of the measured values y1; y2; yp of the measured variable Y of the at least one sensor at the at least one second measuring point 82 is preferably checked.This is preferably done by changing the bearer ring pressure, preferably by adjusting the bearer rings 86; 87; 88; 89 relative to one another by means of the at least one actuator 98; 99; 101; 102. Measured values of the measured variable Y are preferably determined by the at least one sensor at the at least one second measuring point 82 in at least three measuring states. For example, in a first measuring state, at least one measured value is determined, wherein the at least two bearer rings 86; 87; 88; 89 rolling on one another are arranged out of contact with one another. For example, in a second measuring state, at least one measured value is determined, wherein the at least two bearer rings 86; 87; 88; 89 rolling on one another are arranged in contact with one another and wherein the pressure is half the value to be applied in the bearer ring pressure Mp to be set.For example, in a third measuring state, at least one measured value is determined, wherein the at least two bearer rings 86; 87; 88; 89 rolling on one another are arranged in contact with one another and wherein the pressure is the bearer ring pressure Mp to be set. For example, the linearity check is also carried out on the at least one second processing unit 05; 06; 07. Preferably, the computing unit calculates a curve from the at least three measured values, for example, mean values formed from a plurality of individual measured values, and more preferably compares this with the straight line equation to determine the bearer ring pressure to be set.
[0102] Advantageously, by determining and / or checking the at least one measured value yp of the set bearer ring pressure Mp at the at least one, preferably second, measuring point 82 of the at least one first processing unit 05; 06; 07, the at least one sensor is calibrated in order to be used at a measuring point of the same construction on another processing unit 05; 06; 07.
[0103] The at least one sensor is preferably moved from the measuring arrangement, in particular the second measuring arrangement, to a further measuring arrangement, in particular to the third measuring arrangement, on the at least one second processing unit 05; 06; 07, i.e. preferably to the measuring point 82 corresponding to the previously used one. The at least one sensor is preferably adjusted in its position so that the at least one sensor determines the measured variable Y at at least one measuring point 82, preferably the measuring point 82 corresponding to the second measuring point 82 of the first processing unit 05; 06; 07, of the at least one second processing unit 05; 06; 07. The measuring part of the sensor is aligned with the measuring point 82 now to be measured. The at least one sensor is preferably disassembled from the at least one first processing unit 05; 06; 07 and mounted on the at least one second processing unit 05; 06; 07.
[0104] The at least one sensor is therefore preferably arranged selectively on the at least one first processing unit 05; 06; 07 or on the at least one second processing unit 05; 06; 07. Preferably, the at least one sensor is arranged selectively in the first measuring arrangement, the second measuring arrangement, or the third measuring arrangement. Preferably, the at least one sensor selectively performs the second measuring operation or the third measuring operation, particularly preferably additionally selectively the first measuring operation.
[0105] Advantageously, in order to check and / or adjust the bearer ring pressure that was set on the at least one second processing unit 05; 06; 07 during the assembly of the cylinders 32; 33, the at least one measured value yp of the set bearer ring pressure Mp is determined in the third measuring operation. For example, the basic setting of the at least one second processing unit 05; 06; 07 is also carried out in this way. In a further, in particular the third, measuring operation, the at least one sensor in the further, in particular third, measuring arrangement determines the set bearer ring pressure Mp on the at least one second processing unit 05; 06; 07. In this case, the same sensor is preferably used as in the second measuring operation, in particular in the second measuring arrangement. It is crucial that the same sensor is used at the corresponding measuring points 82 of the two processing units 05; 06; 07 to compare the measured values yp.In particular, the measured value yp of the currently set bearer ring pressure is determined. For example, at least two, preferably at least five, individual measured values are determined, the mean of which is calculated. The mean value then preferably describes the determined measured value yp. Preferably, the at least one determined measured value yp is stored in at least one data set. Preferably, the at least one computing unit accesses the at least one data set.
[0106] The determined measured values yp of the set bearer ring pressures Mp of the processing units 05; 06; 07 are compared. The at least one measured value yp determined in the further, in particular third, measuring arrangement on the at least one second processing unit 05; 06; 07, preferably at the at least one second measuring point 82, is preferably compared with the at least one measured value yp determined in the, preferably second, measuring arrangement on the at least one first processing unit 05; 06; 07, preferably at the at least one second measuring point 82. In particular, the measured values yp of the corresponding measuring points 82 are compared. The comparison is carried out, for example, by an operator. However, the comparison is preferably carried out by the at least one computing unit.A deviation of the at least one measured value yp of the at least one second processing unit 05; 06; 07 from the at least one measured value yp of the at least one first processing unit 05; 06; 07 is determined.
[0107] The bearer ring pressure of the at least one second processing unit 05; 06; 07 is preferably adjusted depending on the comparison. The bearer rings 86; 87; 88; 89 of the at least one second processing unit 05; 06; 07 are preferably adjusted relative to one another depending on the comparison, so that at least one further measured value yp of the at least one second processing unit 05; 06; 07 corresponds or would correspond to the at least one measured value yp of the at least one first processing unit 05; 06; 07, i.e. corresponds to the bearer ring pressure Mp to be set. The adjustment is preferably carried out by actuating the at least one actuator 98; 99; 101; 102 and thereby a relative adjustment of the bearer rings 86; 87; 88; 89 rolling on one another.The at least one computing unit that accesses the at least one data set is preferably connected in terms of data technology to at least the at least one second processing unit 05; 06; 07, preferably to at least one control unit that controls it and / or its at least one actuator 98; 99; 101; 102. Preferably, the at least one actuator 98; 99; 101; 102 of the at least one second processing unit 05; 06; 07 is actuated as a function of the comparison, preferably by the at least one control unit. Advantageously, the bearer ring pressure Mp to be set is set on at least two processing units 05; 06; 07 without complex basic settings. This advantageously shortens the machine setup time.
[0108] Preferably, the at least one display unit displays the at least two measured values yp to be compared and / or a result of the comparison of the measured values yp determined by the at least one computing unit, for example on a monitor.
[0109] Preferably, one of the cylinders 32; 33 is designed as a forme cylinder 32 and is free of printing forms during at least one measuring operation of the measuring operations, preferably at least the first measuring operation. Additionally or alternatively, the at least one printing forme is removed from at least one of the cylinders 32; 33 during at least one measuring operation of the measuring operations, preferably before determining the at least one measured value yp of the set bearer ring pressure Mp.
[0110] The at least one measured value yp determined in the second measuring arrangement on the at least one first processing unit 05; 06; 07 and / or the at least one measured value yp determined in the third measuring arrangement on the at least one second processing unit 05; 06; 07 are preferably determined during a processing operation.
