The purpose of the present invention is to propose a device for controlling and/or regulating the setting elements in the sheet delivery region of a sheet printing machine.

Description

Die Erfindung bezieht sich auf eine Einrichtung zur Regelung und/oder Steuerung einzelner Stellelemente im Bereich des Auslegers einer Bogendruckmaschine, wobei mindestens eine Eingabevorrichtung zur Eingabe von bogen- und druckmaschinenspezifischen Kenndaten und mindestens eine Rechenvorrichtung zur Weiterverwendung der Kenndaten vorgesehen sind und wobei weiterhin eine Steuervorrichtung vorgesehen ist, die bei einzelnen Stellelementen eine formatabhängige Einstellung gemäß den angegebenen Kenndaten veranlaßt.The invention relates to a device for regulating and / or controlling individual control elements in the area of the delivery of a sheet printing machine, wherein at least one input device for entering sheet and press-specific characteristics and at least a computing device for further use the characteristics are provided and where a control device is also provided, a format-dependent for individual control elements Adjustment according to the specified characteristics prompted.

Aus der DE 34 13 179 A1 ist bereits eine Steuer- und Regelvorrichtung für den Bogenausleger einer Bogendruckmaschine bekannt geworden. Über mindestens eine Eingabevorrichtung werden das Bogenformat, das Papiergewicht sowie die Drehzahl der Maschine in eine Recheneinrichtung eingegeben. Formatabhängige Einstellungen werden entsprechend den Eingabedaten vorgenommen. Darüber hinaus erfolgt beispielsweise die Einstellung der Greiferöffnungskurve oder die Einstellung der Saugwalze nach Sollwerten, die für jeden Betriebszustand empirisch ermittelt wurden und in Form von Kennlinienfeldern in einem Speicherelement abgespeichert sind.DE 34 13 179 A1 is already one Control and regulating device for the sheet delivery a sheetfed press. Be at least one input device the sheet format, the paper weight and the Speed of the machine in a computing device entered. Format-dependent settings made according to the input data. In addition, the setting is made, for example the gripper opening curve or the setting the suction roll according to setpoints for each Operating condition were determined empirically and in Form of characteristic curve fields in a storage element are saved.

Als Nachteil dieser Erfindung darf sicherlich angesehen werden, daß die empirischen Ermittlungen der jeweiligen Einstelldaten in Abhängigkeit von den Größen Papiergewicht und Drehzahl sehr langwierig sind. Darüber hinaus muß die Ermittlung dieser Kennlinienfelder von einem qualifizierten Fachmann durchgeführt werden. Die Abspeicherung der Kenndatenfelder erfordert weiterhin eine hohe Speicherkapazität.The disadvantage of this invention can certainly be be considered that the empirical investigation of the respective setting data depending of the sizes paper weight and speed very are tedious. In addition, the investigation of these characteristic fields from a qualified Be carried out by a specialist. The saving the characteristic data fields still require one high storage capacity.

Probleme dürften sich auch daraus ergeben, daß die Kennlinienfelder keine kontinuierlichen Kennlinien enthalten. Vielmehr werden die Messungen bei einigen feststehenden Parameterkombinationen durchgeführt; anschließend werden die gemessenen Werte interpoliert. Darüber hinaus ist in der DE 34 13 179 A1 vorgesehen, daß zur Optimierung der Bogenauslage vom Drucker einzelne Einstellwerte korrigiert werden können, was zu Unstetigkeiten in den Kennlinien führt.Problems may also arise from that the characteristic fields are not continuous Characteristic curves included. Rather, the measurements with some fixed parameter combinations carried out; then the measured Interpolated values. In addition, in DE 34 13 179 A1 provided that for optimization individual settings for the sheet delivery from the printer can be corrected, causing discontinuities leads in the characteristic curves.

Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Einrichtung zur Steuerung und/oder Regelung der Stellelemente im Bogenauslegerbereich einer Bogendruckmaschine vorzuschlagen, die unter Verwendung von papierspezifischen und druckmaschinenspezifischen Kenndaten die Einstellwerte der Stellelemente des Bogenauslegers bestimmt.Based on this state of the art the object of the present invention is a device for control and / or regulation of the control elements in the sheet delivery area Propose sheetfed press that using of paper-specific and press-specific Characteristics of the setting values of the Control elements of the bow boom determined.

Diese Aufgabe wird dadurch gelöst, daß die Recheneinrichtung aus den Kenndaten die Energie des in der Auslage ankommenden Bogens berechnet, daß die Rechenvorrichtung weiterhin entsprechend den errechneten Energiewerten die Ansteuergrößen für die Saugwalze und/oder die Greiferöffnungskurve derart bestimmt, daß die durch diese Elemente bewirkte Energieentnahme im wesentlichen der Energie des im Auslegerbereich ankommenden Bogens entspricht und daß die Steuervorrichtung die Saugwalze und/oder die Greiferöffnungskurve entsprechend den errechneten Werten ansteuert.This object is achieved in that the Calculator from the characteristic data the energy of the sheet arriving in the delivery, that the computing device continues accordingly the control values for the calculated energy values for the suction roll and / or the gripper opening curve so determined that by this Essentially effecting energy extraction the energy of the arriving in the boom area Arc corresponds and that the control device the suction roll and / or the gripper opening curve according to the calculated values controls.

Gemäß einer vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens berechnet die Rechenvorrichtung die Saugkraft der Saugwalze nach der Formel F = m * v2 2 * µ * s , wobei m die Masse des Bogens, v die Geschwindigkeit des in der Auslage ankommenden Bogens. µ einen Reibwert und s die Papierlänge, über die die Saugkraft der Saugwalze wirkt, darstellt. Bei konstanter Papierlänge s, über die die Saugkraft der Saugwalze wirkt, d. h. bei fester Einstellung der Greiferöffnungskurve, ändert sich die Saugkraft F der Saugwalze in Abhängigkeit von dem Quadrat der Geschwindigkeit des in der Bogenauslage ankommenden Bogens.According to an advantageous embodiment of the method according to the invention, the computing device calculates the suction force of the suction roll according to the formula F = m * v 2nd 2 * µ * s , where m is the mass of the sheet, v is the speed of the sheet arriving in the delivery. µ represents a coefficient of friction and s the length of paper over which the suction force of the suction roller acts. With a constant paper length s over which the suction force of the suction roller acts, ie with a fixed setting of the gripper opening curve, the suction force F of the suction roller changes depending on the square of the speed of the sheet arriving in the sheet delivery.

Gemäß einer Weiterentwicklung des erfindungsgemäßen Verfahrens ist vorgesehen, daß bei Erreichen der maximalen Saugkraft Fmax die Steuervorrichtung die Greiferöffnungskurve derart variiert, daß die Papierlänge, über die die Saugkraft der Saugwalze wirkt, gemäß der Formel s = m * v2 2 * µ * Fmax geändert wird.According to a further development of the method according to the invention, it is provided that when the maximum suction force F max is reached, the control device varies the gripper opening curve in such a way that the paper length over which the suction force of the suction roller acts, according to the formula s = m * v 2nd 2 * µ * F Max will be changed.

Gemäß einer alternativen Ausführungsform der erfindungsgemäßen Einrichtung ist vorgesehen, daß die Recheneinrichtung in Abhängigkeit von der Energie, mit der der Bogen in der Auslage ankommt, die Papierlänge s, über die die Saugkraft der Saugwalze wirkt, gemäß der Formel s = m * v2 2 * µ * F berechnet. Bei Erreichen der Stellgrenze der maximal möglichen Papierlänge smax, über die die Saugkraft der Saugwalze wirkt, errechnet die Recheneinrichtung die Saugkraft der Saugwalze gemäß der Formel F = m * v2 2 * µ * smax Üblicherweise wird die Vorgehensweise derart sein, daß die Saugkraft entsprechend der zuvor genannten Formel F = m * v2 2 * µ * s berechnet wird. s wird dabei vorerst konstant gehalten. Bei der Einstellung von s wird berücksichtigt, daß der Bogen um so besser zur Ablage ankommt, je länger er durch die Greifer geführt wird, d. h., je kürzer s ist. Nur in Ausnahmefällen wird eine Korrektur der Bogenauslage daher über eine Änderung der Papierlänge s, über die die Saugkraft der Saugwalze wirkt, vorgenommen werden.According to an alternative embodiment of the device according to the invention, it is provided that the computing device, depending on the energy with which the sheet arrives in the delivery, the paper length s over which the suction force of the suction roller acts, according to the formula s = m * v 2nd 2 * µ * F calculated. When the setting limit of the maximum possible paper length s max over which the suction force of the suction roller acts is reached, the computing device calculates the suction force of the suction roller according to the formula F = m * v 2nd 2 * µ * s Max Usually, the procedure will be such that the suction force according to the aforementioned formula F = m * v 2nd 2 * µ * s is calculated. s is kept constant for the time being. When setting s, it is taken into account that the longer the sheet is fed through the grippers, the shorter s is. Only in exceptional cases will the sheet delivery be corrected by changing the paper length s over which the suction force of the suction roller acts.

In einer Weiterbildung der erfindungsgemäßen Einrichtung wird vorgeschlagen, daß Eingabevorrichtungen vorgesehen sind, die der Rechenvorrichtung Informationen über den jeweiligen Farb-, Lack-, Feuchtmittel- und/oder Puderauftrag auf den Bogen zuführen, und daß die Rechenvorrichtung diesen Massezuwachs bei der Berechnung der Energie des in der Auslage ankommenden Bogens berücksichtigt. Beispielsweise kann Information über die auf den Bogen aufgetragene Farbmenge über die Stellung der Farbschieber erhalten werden. Problemlos läßt sich auch der Lack-, Feuchtmittel- und/oder Puderauftrag auf dem Bogen feststellen.In a development of the invention It is proposed that input devices are provided that the computing device Information about the respective color, Paint, dampening solution and / or powder application on the Feed sheet, and that the computing device this increase in mass when calculating the Energy of the sheet arriving in the delivery considered. For example, information about the amount of paint applied to the sheet can be obtained via the position of the color slider. The varnish, dampening solution and / or determine powder application on the sheet.

Alternativ oder zusätzlich ist eine Eingabevorrichtung vorgesehen, über die der Drucker die Saugkraft F der Saugwalze oder die Papierlänge s, über die die Saugkraft der Saugwalze wirkt, mittels eines Korrekturfaktors k beeinflußt. Wird beispielsweise in dem ursprünglichen Rechenprogramm der Massezuwachs durch den Farb-, Lack-, Feuchtmittel- oder Puderauftrag nicht berücksichtigt, so ist dem Drucker hierdurch die Möglichkeit gegeben, durch eine Korrektur der Saugkraft der Saugwalze bzw. durch eine Korrektur der Greiferöffnungskurve auf die Ablage des Bogens einzuwirken.An input device is alternatively or additionally provided by which the printer uses the Suction force F of the suction roller or the paper length s, by means of which the suction force of the suction roller acts a correction factor k affects. For example in the original calculator Mass increase due to the color, varnish, dampening solution or powder application is not taken into account this gives the printer the opportunity by correcting the suction force of the suction roller or by correcting the gripper opening curve to act on the storage of the sheet.

In einer Weiterbildung wird vorgeschlagen, daß ein von dem Drucker eingegebener Korrekturfaktor k bei der Berechnung der Saugkraft F der Saugwalze bzw. bei der Berechnung der Papierbogenlänge s berücksichtigt wird und daß bei Erreichen der Stellgrenze der Saugkraft Fmax bzw. bei Erreichen der maximalen Papierlänge smax der angegebene Korrekturfaktor zur Berechnung der Papierlänge s bzw. zur Berechnung der Saugkraft F übernommen wird. Die Verwendung eines Korrekturfaktors bietet den Vorteil, daß Korrekturen über den gesamten Geschwindigkeitsbereich wirksam werden, wodurch keine Unstetigkeiten in den Einstellwerten der Stellelemente auftreten.In a further development it is proposed that a correction factor k entered by the printer be taken into account in the calculation of the suction force F of the suction roller or in the calculation of the paper sheet length s and that when the setting limit of the suction force F max or when the maximum paper length s is reached max the specified correction factor for calculating the paper length s or for calculating the suction force F is adopted. The use of a correction factor offers the advantage that corrections take effect over the entire speed range, as a result of which there are no discontinuities in the setting values of the adjusting elements.

Vorteilhaft ist es hierbei, wenn der aufgefundene Korrekturfaktor k, der die o.k.-Einstellungen in Abhängigkeit von den vorgegebenen Parametem bewirkt, bei Druckauftragsende in den Speicher der Recheneinrichtung übernommen wird. Der gespeicherte Wert wird dann automatisch als Vorgabe bei einem Folgeauftrag mit gleichen Parametem übernommen, so daß eine erneute Korrektur der Einstellungen der Saugwalze bzw. der Greiferöffnungskurve nicht oder nur geringfügig notwendig wird.It is advantageous here if the one found Correction factor k, which is the ok settings in Dependency on the given parameters causes in the memory of the Computing device is taken over. The saved one The value is then automatically set as the default a follow-up order with the same parameters, so that a new correction of the settings the suction roll or the gripper opening curve not or only marginally necessary becomes.

In einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens ist vorgesehen, daß die Steuervorrichtung die Pudervorrichtung derart ansteuert, daß die in Abhängigkeit von der Maschinengeschwindigkeit pro Fläche aufgetragene Pudermenge konstant ist. Weiterhin ist vorgesehen, daß die Rechenvorrichtung die auf einem Bogen aufgebrachte Pudermenge in Abhängigkeit von der Endstapelhöhe berechnet. So kann beispielsweise die auf den Bogen aufgebrachte Pudermenge von der Unterkante des Stapels bis zur Oberkante des Stapels linear abnehmen. Da der Druck auf die unteren Bogen wesentlich höher ist als auf die oberen, wird hierdurch ein Verkleben der Bogen im unteren Bereich des Stapels vermieden.In a further embodiment of the invention The procedure provides that the Control device controls the powder device in such a way that depending on the machine speed amount of powder applied per surface is constant. It is also provided that that the computing device on a sheet amount of powder applied depending on the End stack height calculated. For example the amount of powder of the bottom edge of the stack to the top edge of the Remove the stack linearly. Because the pressure on the lower arch is much higher than on the upper, this will cause the sheets to stick together avoided lower area of the stack.

Gemäß einer Ausgestaltung der erfindungsgemäßen Einrichtung wird vorgeschlagen, daß der Steuervorrichtung über die Eingabevorrichtung Daten über die Massenverteilung eines bedruckten Bogens zuführbar sind und daß die Steuervorrichtung die Blasdüsen so ansteuert, daß über die Fläche des Bogens eine Druckverteilung erzeugt wird, die mit der Massenverteilung des Bogens korreliert.According to an embodiment of the invention It is proposed that the Control device via the input device data about the mass distribution of a printed Sheet can be fed and that the control device controls the blow nozzles so that the Surface of the arch creates a pressure distribution will that with the mass distribution of the bow correlated.

Da die Blasdüsen durch die Steuervorrichtung derart angesteuert werden, daß die Druckverteilung der realen flächenhaften Massenverteilung des Bogens entspricht, kann der Bogen exakt und schnell auf dem Stapel abgelegt werden. Unter Umständen kann es vorteilhaft sein, die Blasdüsen so einzustellen, daß infolge der Druckverteilung der Bogen zuerst in der Bogenmitte abgelegt wird. Die Ablage kann jedoch auch so erfolgen, daß ausgehend von der zuerst abgelegten Stelle, welche in der Regel außermittig liegt, die Luft unter den Bogen schnell ihren Weg nach außen findet. So können die von oben auf den Bogen wirkenden Blasluftdüsen evtl. durch seitlich vom Stapel angeordnete Saugvorrichtungen unterstützt werden.Because the blow nozzles through the control device can be controlled such that the pressure distribution the real areal mass distribution of the arch corresponds, the bow can be exact and fast placed on the stack. In certain circumstances it may be advantageous to adjust the blow nozzles that due to the pressure distribution of the sheets first placed in the middle of the sheet. Filing can, however, also take place so that starting from the first filed, which is usually is off-center, the air under the arches quickly finds its way out. So those of blowing air nozzles possibly acting on top of the bend by suction devices arranged on the side of the stack get supported.

Die flächenhafte Massenverteilung kann mit Hilfe der Rechenvorrichtung exakt bestimmt werden, wenn dieser die Daten über die Papierdicke, den Farb-, Puder- und/oder Lackauftrag zugeleitet werden. Beispielsweise kann die Information über die Farbverteilung über die Stellung der Farbzonenschrauben ermittelt werden. Auch ist es vorteilhaft, wenn zur Ermittlung der Massenverteilung die Oberfläche des Bogens in matrixartige Flächenelemente zergliedert wird und für diese Flächenele mente neben dem Papiergewicht die Masse der Farbe, des Lacks, des Feuchtmittels und des Puders abzüglich der Verdunstung bzw. des Puderverlustes ermittelt wird. Als Hilfseinrichtungen können dabei Einrichtungen zur Messung des Gewichtes des Stapels vor dem Drucken und nach dem Drucken installiert sein. Die Einstellung einer der Massenverteilung entsprechenden Druckverteilung mittels der Blasdüsen kann in Abhängigkeit von der konstruktiven Ausführungsform in vielfältiger Art und Weise erfolgen. So ist es möglich, die Blasluftmenge, die Anzahl der zugeschalteten Blasdüsen sowie die Richtung der Blaswirkung in Abhängigkeit von den bekannten bogen- und maschinenspezifischen Daten zu variieren.The areal mass distribution can with Can be determined exactly with the aid of the computing device, if this is the data about the paper thickness, the paint, powder and / or paint application supplied become. For example, the information about the color distribution via the position of the ink fountain keys be determined. It is also advantageous if to determine the mass distribution Surface of the arch in matrix-like surface elements is broken up and for these surface elements in addition to the paper weight, the mass of the Paint, varnish, dampening solution and powder minus evaporation or loss of powder is determined. As auxiliary facilities can thereby devices for measuring the weight the stack before printing and after Print installed. Hiring one of the Mass distribution corresponding pressure distribution by means of the blowing nozzles depending on the constructive embodiment in various ways and way. So it is possible to control the amount of blown air, the number of activated blowing nozzles as well as the direction of the blowing effect depending from the well-known sheet and machine specific Data to vary.

Konstruktiv vorteilhaft ist es, wenn oberhalb des Stapels eine Blasluftvorrichtung vorgesehen ist, die matrixförmig über die Oberfläche eines Bogens verteilte Luftaustrittsdüsen aufweist, wobei die Düsen mittels der Steuervorrichtung einzeln mit Blasluft beaufschlagt sind. Damit ist es möglich, an den Düsen, welche auf einen Bereich des Bogens wirken, der zuerst abgelegt werden soll, früher Blasluft austreten zu lassen als bei den restlichen Düsen. Beispielsweise werden die Düsen von der Hinterkante beginnend in Richtung Vorderkante reihenweise abgeschaltet.It is structurally advantageous if above a blown air device is provided in the stack, the matrix shape over the surface of an arch has distributed air outlet nozzles, the nozzles by means of the control device individually with blown air are acted upon. This makes it possible for the Nozzles that act on an area of the arc, which should be put down first, formerly blowing air to let out than with the remaining nozzles. For example, the nozzles are from the trailing edge starting in rows towards the front edge switched off.

Die Erfindung wird anhand der nachfolgenden Zeichnungen näher erläutert.The invention is based on the following Drawings explained in more detail.

It shows:
Fig. 1
a schematic side view of the delivery area of a sheet-fed rotary printing press and
Fig. 2
a sketched representation of the quantities calculable by means of the method according to the invention.

In Fig. 1 ist in schematischer Seitenansicht ein Bogenausleger 1 einer nicht dargestellten Bogenrotationsdruckmaschine dargestellt. Die Ketten 2 mit den Greiferbrücken 3 laufen über die Umlenkräder 4, 5. Die Greiferbrücken befördern die Bogen 6 in Richtung des Auslagestapels 7. Eine Abbremsung des Bogens erfolgt über die Saugwalze 9, sobald der Bogen 6 über dem Auslagestapel 7 durch die Greiferbrücken 3 losgelassen wird. Die Greiferbrükken 3 werden über die Greiferöffnungskurve 10 gesteuert. Ein Niederdrücken des Bogens 6 auf den Auslagestapel 7 erfolgt mittels der Blasdüsen 11.In Fig. 1 is a schematic side view Sheet delivery 1 of a sheet-fed rotary printing machine, not shown shown. The chains 2 with the gripper bridges 3 run over the deflection wheels 4, 5. The gripper bridges convey the sheets 6 in Direction of the delivery stack 7. A deceleration of the sheet takes place via the suction roller 9 as soon as the sheet 6 above the delivery stack 7 through the Gripper bridges 3 is released. The grapple bridges 3 are on the gripper opening curve 10 controlled. Depressing the arch 6 the delivery stack 7 takes place by means of the blowing nozzles 11.

Die Ablage des Bogens 6 auf dem Auslagestapel 7 sollte idealerweise derart erfolgen, daß die Bremskraft F der Saugwalze 9 und die wirksame Bremsstrecke s so bemessen sind, daß bei Erreichen der Hinterkante des Auslagestapels 7 die kinetische Energie des Bogens 6 zumindest sehr gering ist. Hierdurch wird verhindert, daß der Bogen zu hart gegen die Stapelanschläge 8 prallt, was zu Beschädigungen des Bogens 6 führen würde.The placement of sheet 6 on the delivery stack 7 should ideally be such that the Braking force F of the suction roller 9 and the effective one Braking distance s are dimensioned so that when reached the rear edge of the delivery stack 7 die kinetic energy of the arch 6 at least very much is low. This prevents the bow crashes too hard against the stacking stops 8, which would damage the arch 6.

Erfindungsgemäß wird die Einstellung der Saugwalze und/oder der Greiferöffnungskurve derart gesteuert, daß diese Bedingung stets erfüllt ist.According to the setting of the Suction roll and / or the gripper opening curve in such a way controlled that this condition is always met.

Die Größen, die zur Berechnung der Einstellung der Saugwalze 9 bzw. zur Einstellung der Greiferöffnungskurve dienen, sind in Fig. 2 schematisch dargestellt.The sizes used to calculate the setting the suction roller 9 or to adjust the Serve gripper opening curve are schematic in Fig. 2 shown.

Fig. 2 stellt im wesentlichen den Bereich um die Saugwalze 9 gemäß Fig. 1 dar. Der Bogen 6 wird von der Greiferbrücke 3 über die Saugwalze 9 geführt. Die Saugwalze 9 ist an eine in der Zeichnung nicht dargestellte Unterdruckquelle angeschlossen. Die Saugkraft F der Saugwalze 9 ist einstellbar. So lange der Bogen 6 von den Greiferbrücken 3 geführt wird, bewegt er sich mit Maschinengeschwindigkeit. Wird der Bogen 6 von der Greiferbrücke 3 losgelassen, erfolgt infolge der Saugkraft F der Saugwalze 9 ein Abbremsen des Bogens 6. s kennzeichnet die Papierlange des Bogens 6, über die die Saugkraft F der Saugwalze 9 wirkt. Unter Berücksichtigung des Reibwertes u läßt sich die Energie, die von der Saugwalze 9 zur Bremsung des Bogens 6 und damit zur Entnahme der Energie aus dem Bogen 6 aufgebracht wird, nach der Formel E = F * µ * s berechnen. Im Idealfall ist diese Entnahme der Energie aus dem Bogen gleich der kinetischen Energie 1/2 * m * v2 des im Auslegerbereich einer Bogenrotationsdruckmaschine ankommenden Bogens 6.2 essentially represents the area around the suction roller 9 according to FIG. 1. The sheet 6 is guided by the gripper bridge 3 over the suction roller 9. The suction roller 9 is connected to a vacuum source, not shown in the drawing. The suction force F of the suction roller 9 is adjustable. As long as the sheet 6 is guided by the gripper bridges 3, it moves at machine speed. If the sheet 6 is released from the gripper bridge 3, the sheet 6 is braked as a result of the suction force F of the suction roller 9. The paper length of the sheet 6 is identified by s. The suction force F of the suction roller 9 acts on it. Taking into account the coefficient of friction u, the energy which is applied by the suction roller 9 for braking the sheet 6 and thus for extracting the energy from the sheet 6 can be according to the formula E = F * µ * s to calculate. Ideally, this removal of the energy from the sheet is equal to the kinetic energy 1/2 * m * v 2 of the sheet 6 arriving in the delivery area of a sheet-fed rotary printing press.

Wie bereits erwähnt, kennzeichnet die Größe s die Papierlänge des Bogens 6, über die die Saugkraft F der Saugwalze 9 wirkt, nachdem der Bogen 6 von der Greiferbrücke 3 nicht mehr geführt wird. Zu beachten ist, daß sich die Saugwalze selbst evtl. auch dreht. Nur im Fall, daß die Saugwalze steht, kennzeichnet s die Papierlänge des Bogens 6 hinter der Saugwalze 9. Dreht sich die Saugwalze 9 in Papierlaufrichtung oder gegen die Papierlaufrichtung, so muß zusätzlich die Umfangsstrecke der Saugwalze 9 vom Zeitpunkt der öffnung der Greiferbrücken 3 bis zu dem Zeitpunkt, an dem der Bogen 6 die Saugwalze 9 passiert hat, berücksichtigt werden. Um diese Umfangsstrecke muß die Papierlänge s des Bogens 6 hinter der Saugwalze 9 bei Drehen in Papierlaufrichtung vermindert und bei Drehen gegen die Papierlaufrichtung erhöht werden.As already mentioned, the size s the paper length of the sheet 6, over which the suction power F of the suction roller 9 acts after the arc 6 is no longer guided by the gripper bridge 3. It should be noted that the suction roller itself possibly also rotates. Only in the event that the suction roller stands, s denotes the paper length of the sheet 6 behind the suction roller 9. The suction roller rotates 9 in the paper direction or against the paper direction, so the circumferential distance must also the suction roller 9 from the time of opening Gripper bridges 3 until the time when the Sheet 6 has passed the suction roller 9 is taken into account become. In order to cover this circumferential distance Paper length s of the sheet 6 behind the suction roller 9 reduced when rotating in the direction of paper movement and increased when turning against the paper feed direction become.

Generell läßt sich sagen, daß die Ablage des Bogens 6 um so besser erfolgt, je länger der Bogen 6 durch die Greiferbrücken 3 geführt wird, d. h., je kürzer die Papierlänge s, über die die Saugkraft F der Saugwalze 9 wirkt, ist. Die günstigste Vorgehensweise zur Berechnung der Einstellungen der Stellelemente im Auslegerbereich wird daher die sein, daß die Einstellung der Greiferöffnungskurve 10 vorerst konstant ist. Die Saugkraft F der Saugwalze 9 läßt sich dann gemäß der Formel F = m * v2 2 * µ * s in Abhängigkeit vom Quadrat der Geschwindigkeit v des im Auslegerbereich der Druckmaschine ankommenden Bogens 6 berechnen. Die zur Berechnung notwendigen Daten, wie die Masse des Bogens, bzw. seine Länge, Breite, Dicke und Dichte, ebenso wie die Geschwindigkeitsinformation, werden einem Rechner 13 über eine Eingabevorrichtung 12 zugeführt. Diese Eingabe erfolgt entweder über das Bedienpersonal oder über entsprechende Meßstellen an der Druckmaschine selbst. Beispielsweise kann über die Druckbeistellung und die Deckmarkenhöheneinstellung die Papierdicke ermittelt werden. Formatabhängige Informationen lassen sich anhand der Ziehmarkenposition oder mittels der Farbzoneneinstellung erhalten. Die Geschwindigkeit des im Auslegerbereichs ankommenden Bogens 6 ist ohne weiteres aus der Drehgeschwindigkeit der Druckmaschine bestimmbar. Information über den Farbauftrag in den einzelnen Druckwerken, der evtl. für die Korrektur der Masse m des Bogens 6 berücksichtigt wird, kann aus der Stellung der Farbzonenschrauben ermittelt werden. In ähnlicher Weise kann dem Rechner auch die Menge des auf den Bogen aufgetragenen Lackes, Feuchtmittels oder Puders bereitgestellt werden.In general, it can be said that the sheet 6 is deposited the better the longer the sheet 6 is guided through the gripper bridges 3, ie the shorter the paper length s over which the suction force F of the suction roller 9 acts. The cheapest procedure for calculating the settings of the adjusting elements in the boom area will therefore be that the setting of the gripper opening curve 10 is initially constant. The suction force F of the suction roller 9 can then be according to the formula F = m * v 2nd 2 * µ * s as a function of the square of the speed v of the sheet 6 arriving in the delivery area of the printing press. The data required for the calculation, such as the mass of the sheet or its length, width, thickness and density, as well as the speed information, are fed to a computer 13 via an input device 12. This input is made either by the operating personnel or via corresponding measuring points on the printing press itself. For example, the paper thickness can be determined via the print delivery and the cover mark height adjustment. Format-dependent information can be obtained from the position of the drawing mark or from the color zone setting. The speed of the sheet 6 arriving in the delivery area can easily be determined from the speed of rotation of the printing press. Information about the ink application in the individual printing units, which may be taken into account for the correction of the mass m of the sheet 6, can be determined from the position of the ink fountain keys. In a similar manner, the amount of lacquer, dampening solution or powder applied to the sheet can also be made available to the computer.

Ist gemäß der Formel F = m * v2 2 * µ * s , wobei s konstant ist, die Stellkraft F der Saugwalze 9 erreicht, so berechnet der Rechner die notwendige Korrektur bei der Einstellung der Greiferöffnungskurve 10 über die Formel s = m * v2 2 * µ * Fmax Sollte es aus irgendwelchen Gründen vorkommen, daß beispielsweise die berechnete Saugkraft F der Saugwalze 9 bei fester Einstellung der Greiferöffnungskurve 10 nicht zu einer optimalen Auslage des Bogens 6 führt, so ist dem Bedienpersonal über die Eingabevorrichtung 12 die Möglichkeit gegeben, die Saugkraft F der Saugwalze 9 über einen Korrekturfaktor k zu beeinflussen. Wird bei Hochfahren der Geschwindigkeit v die Steligrenze der Saugkraft Fmax der Saugwalze 9 erreicht, so berücksichtigt der Rechner 13 diesen Korrekturfaktor auch bei der Berechnung der Papierlänge s. Selbstverständlich läßt sich s auch direkt durch den Korrekturfaktor k beeinflussen. Günstig bei dieser Vorgehensweise ist, daß die Korrektur über den gesamten Geschwindigkeitsbereich wirksam wird und so zu keinen Unstetigkeiten in der Einstellung der Saugkraft bzw. der Papierlänge s, über die die Saugkraft F wirkt, führt.Is according to the formula F = m * v 2nd 2 * µ * s , where s is constant, the actuating force F of the suction roller 9 is reached, the computer calculates the necessary correction when setting the gripper opening curve 10 using the formula s = m * v 2nd 2 * µ * F Max If, for any reason, it should happen that, for example, the calculated suction force F of the suction roller 9 does not lead to an optimal delivery of the sheet 6 when the gripper opening curve 10 is fixed, then the operating personnel is given the possibility of using the input device 12 to extract the suction force F of the suction roller 9 to influence via a correction factor k. If the final limit of the suction force F max of the suction roller 9 is reached when the speed v is increased, the computer 13 also takes this correction factor into account when calculating the paper length s. Of course, s can also be influenced directly by the correction factor k. It is favorable with this procedure that the correction becomes effective over the entire speed range and thus does not lead to any discontinuities in the setting of the suction force or the paper length s over which the suction force F acts.

Desweiteren ist vorgesehen, daß die Korrekturfaktoren in Abhängigkeit von den eingegebenen Parametern in eine Speichereinrichtung übernommen werden. Diese Korrekturen werden bei Folgeaufträgen mit gleichen Parametem automatisch zur Einstellung der Saugkraft F der Saugwalze 9 bzw. zur Einstellung der Greiferöffnungskurve 10 berücksichtigt.It is also provided that the correction factors depending on the entered Parameters transferred into a storage device become. These corrections are made for follow-up orders automatically with the same parameters Setting the suction force F of the suction roller 9 or taken into account for setting the gripper opening curve 10.
