Definitions
- the invention relates to a method and an arrangement for the lateral alignment of individual sheets on sheet-processing printing presses, in which the sheets to be printed are conveyed against a lateral stop by means of a pneumatic side pulling device arranged below or in the system table and working in time with the incoming sheets.
- a device which uses a measuring head instead of the side drawing mark on the feed table. After aligning the sheet to the front marks, the lateral position of each sheet is determined using a measuring head. The measured value is compared with a target value. The difference results in the extent of the required lateral displacement, which is realized by means of a suction pull bar arranged in the feed table and displaceable transversely to the sheet conveying direction.
- a scanning device having at least one sensor is used.
- a suction box which can be moved laterally to the sheet conveying direction and to which a measuring slot is arranged is arranged in the feed table.
- a sensor is arranged above the measuring slot and is coupled to an electronic evaluation system. The bow is moved laterally using a suction box, the side edge of the sheet being guided past the measuring line formed by the sensor and measuring slot. If the measuring line is exceeded, a signal is generated after the arc is moved a constant distance into its defined position.
- a sheet alignment corresponding to the preamble of claims 1 and 2 is known which conveys the sheet against a lateral stop by means of a pneumatic side pulling device.
- the pneumatic side-pulling device is arranged in or below the system table, works in time with the incoming sheets and consists of a suction cup that can be moved back and forth via a control curve and a valve block with a rotary disk valve.
- the object of the invention is to eliminate the disadvantages known from the prior art known above.
- the solution according to the invention realizes a position detection of the sheet before the alignment in the lateral direction when the sheet lies against the front marks and the preceding one is drawn into the feeder printing unit by the pre-gripper.
- the sheet to be aligned is for a short time no longer covered by the preceding one and the following one has not yet reached the side pulling device.
- the scanning device for detecting the position of the sheet is arranged in this free area. Starting from its arrival position, each sheet is only subjected to suction air by means of the vacuum path-dependent vacuum control as long as its individual deviation from the end position requires it. The movement of the suction cup remains constant with every curve. A correct end position of the sheet is achieved at both lower and higher machine speeds (greater than 12,000 sheets / h).
- the speed of impact of the sheet at the side stop is controlled in a defined manner so that a rebound of the sheet at the front marks is eliminated. Regardless of the machine speed and the time at which the suction air is applied, each sheet is immediately delayed before it arrives at the side mark stop and is moved against the stop at a very low speed. This is achieved via a defined travel time behavior of the control curve, in combination with the individual vacuum path control depending on the travel path. Regardless of the type of paper, this also protects the sheet edges.
- the solution according to the invention consists of a pneumatic side pulling device integrated in a feed table 1 and a In terms of circuitry, sensor 4 connected to it for position detection of a sheet 2.
- Sensor 4 is fixed in sheet feed direction 21 in front of side stop 6, which is attached to cover plate 8, in feed table 1.
- Sensor 4 and side stop 6 are arranged on a line 22 and the sensor 4 extends with its measuring range, starting from line 22, into the area of the feed table 1.
- the measuring range of the sensor 4 is as large as the range of movement of a suction device 7.
- the side pulling device consists of a valve housing 10 in which a drive shaft 9 is received by means of radial bearings 18.
- a control cam 15 is attached to the drive shaft 9, on which a roller 23 runs.
- the roller 23 is connected to a slide 14 which is displaceably mounted on a suction pipe 13 arranged parallel to the drive shaft 9 in the valve housing.
- the carriage 14 carries the replaceable suction device 7 with its suction surface 7.1.
- an opening 12 is provided in the suction pipe 13, which ensures the suction of the air via the suction device 7.
- the sucker 7 is movably coupled to the slide 14 in a recess 11 reaching below the side stop 6 and integrated into the cover plate 8.
- the valve housing 10 has a suction air line 16 connected to a suction pump 19, which is coupled to a solenoid valve 17.
- the solenoid valve 17 is connected to the intake manifold 13 and further connected in terms of circuitry to a signal converter 5, which in turn is coupled to the sensor 4 fixed in the feed table 1.
- a valve 20 e.g. a poppet valve.
- this valve 20 is connected to an end position switch 24 which is arranged on the valve housing 10 and is contacted by means of a suction slide 14 when it has reached its rear end position.
- the operation of the arrangement is described below.
- the sheets 2 separated by the system are fed to the front marks 3 via the obliquely arranged feed table 1, for example a suction belt table.
- Sheet 2 is now on the front marks 3 and the pre-gripper pulls the preceding one into the feeder printing unit. Sheet 2 is therefore no longer covered by the preceding one and the following one has not yet reached the side pulling device.
- the sensor 4 for example a reflection measuring head, is fixed in the feed table 1 for detecting the position of the sheet 2.
- Sensor 4 now determines the individual drawing path for the sheet 2.
- This information is supplied to the solenoid valve 17 in terms of circuitry via the signal converter 5.
- a negative pressure generated by the suction pump 19 and supplied via the suction air line 16 is constantly applied to the solenoid valve 17.
- the sucker 7 is in a position which corresponds to the high point of the control curve 15. While the sheet 2 is in contact with the front marks 3, the suction device 7 is moved to the side stop 6, starting from the drive shaft 9 operating in time with the incoming sheet 2, the control cam 15, roller 23 and the suction slide 14 which can be moved on the suction pipe 13. Depending on the position determined by the sensor 4 and the resulting individual drawing path of the sheet 2, the suction air is switched on sooner or later via the solenoid valve 17 for the constant movement of the suction device 7. Each sheet 2 is conveyed by the suction device 7 against the side stop 6. On the valve housing 10, the limit switch 24 is contacted by the slide 14 and causes the valve 20 to open. The vacuum therefore breaks down quickly.
- the holding force between the suction device 7 and the sheet 2 is dimensioned such that the suction device 7 slips under the sheet 2 when the latter rests against the side stop and is finally released (rear end position). This is realized by a delay phase in the path-time behavior of the control curve 15 and by the now open valve 20 arranged at the free end of the intake manifold 13.

Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Anordnung zum seitlichen Ausrichten von einzelnen Bogen an bogenverarbeitenden Druckmaschinen, bei denen die zu bedruckenden Bogen mittels eines unterhalb bzw. im Anlagetisch angeordneten, im Takt der ankommenden Bogen arbeitenden, pneumatischen Seitenziehorgans gegen einen seitlichen Anschlag gefördert werden.The invention relates to a method and an arrangement for the lateral alignment of individual sheets on sheet-processing printing presses, in which the sheets to be printed are conveyed against a lateral stop by means of a pneumatic side pulling device arranged below or in the system table and working in time with the incoming sheets.
Es sind verschiedene Bogenausrichteinrichtungen bekannt, die mittels ortsfestem Seitenanschlag oder ohne Anschlag bzw. Seitenmarke den Bogen paßgerecht der Druckmaschine zuführen.Various sheet alignment devices are known which feed the sheet to the printing press in a fit manner by means of a fixed side stop or without a stop or side mark.
Aus der DE-AS 2 046 602 ist eine Vorrichtung bekannt, die anstelle der Seitenziehmarke auf dem Anlegetisch einen Meßkopf verwendet. Nach dem Ausrichten des Bogens an den Vordermarken wird die Seitenlage jedes Bogens mittels Meßkopf ermittelt. Der Meßwert wird mit einem Sollwert verglichen. Aus der Differenz ergibt sich das Maß der erforderlichen Seitenverschiebung, die über eine im Anlegetisch angeordnete, quer zur Bogenförderrichtung verschiebbare, Saugziehleiste realisiert wird.From DE-AS 2 046 602 a device is known which uses a measuring head instead of the side drawing mark on the feed table. After aligning the sheet to the front marks, the lateral position of each sheet is determined using a measuring head. The measured value is compared with a target value. The difference results in the extent of the required lateral displacement, which is realized by means of a suction pull bar arranged in the feed table and displaceable transversely to the sheet conveying direction.
Eine weitere Lösung ist aus der DE-PS 3 301 722 C2 bekannt. Anstelle von Anschlag und Seitenmarke wird eine, mindestens einen Sensor aufweisende, Abtasteinrichtung verwendet. Im Anlegetisch ist ein seitlich zur Bogenförderrichtung verschiebbarer Saugkasten angeordnet, dem ein Meßschlitz nachgeordnet ist. Über dem Meßschlitz ist ein Sensor angeordnet, der mit einer Auswerteelektronik gekoppelt ist. Der Bogen wird mittels Saugkasten seitlich bewegt, wobei die Seitenkante des Bogens an der durch Sensor und Meßschlitz gebildeten Meßlinie vorbei geführt wird. Beim Überschreiten der Meßlinie wird ein Signal erzeugt, nachdem der Bogen noch eine konstante Strecke in seine definierte Position bewegt wird.Another solution is known from DE-PS 3 301 722 C2. Instead of the stop and side mark, a scanning device having at least one sensor is used. A suction box which can be moved laterally to the sheet conveying direction and to which a measuring slot is arranged is arranged in the feed table. A sensor is arranged above the measuring slot and is coupled to an electronic evaluation system. The bow is moved laterally using a suction box, the side edge of the sheet being guided past the measuring line formed by the sensor and measuring slot. If the measuring line is exceeded, a signal is generated after the arc is moved a constant distance into its defined position.
Des weiteren ist aus der DE-PS 2 851 935 C3 eine dem Oberbegriff der Patentansprüche 1 und 2 entsprechende Bogenausrichtung bekannt, die mittels einer pneumatischen Seitenzieheinrichtung den Bogen gegen einen seitlichen Anschlag fördert. Die pneumatische Seitenzieheinrichtung ist im bzw. unterhalb des Anlagetisches angeordnet, arbeitet im Takt der ankommenden Bogen und besteht aus einem über eine Steuerkurve hin und her bewegbaren Sauger sowie einem Ventilblock mit Drehscheibenventil.Furthermore, from DE-PS 2 851 935 C3 a sheet alignment corresponding to the preamble of
Nachteilig ist es, daß die genannten Einrichtungen relativ aufwendig sind und bei hohen Maschinengeschwindigkeiten (größer als 12.000 Bogen/h) dynamisch bedingt, die Massenkräfte zunehmen. Somit werden Leistungsgrenzen erreicht, die bei höheren Maschinengeschwindigkeiten zu schlechteren Ergebnissen führen. Das Ziehen der Saugplatte und die Saugluftbeaufschlagung über das Drehscheibenventil erfolgen synchron. Der Bogen wird undefiniert an den Anschlag gefördert und prallt somit mehr oder weniger zurück. Dieser Effekt wirkt sich negativ auf eine paßgerechte Übergabe des jeweiligen Bogens an den Druckzylinder aus.It is disadvantageous that the devices mentioned are relatively complex and, at high machine speeds (greater than 12,000 sheets / h), cause the inertial forces to increase. In this way, performance limits are reached which lead to poorer results at higher machine speeds. Pulling the suction plate and the suction air through the turntable valve are done synchronously. The bow is conveyed to the stop undefined and thus bounces back more or less. This effect has a negative effect on a suitable transfer of the respective sheet to the printing cylinder.
Aufgabe der Erfindung ist es, die aus dem oben bekannten Stand der Technik bekannten Nachteile zu beseitigen.The object of the invention is to eliminate the disadvantages known from the prior art known above.
Erfindungsgemäß wird die Aufgabe gemäß dem Kennzeichen der Ansprüche 1 und 2 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention the object is achieved according to the characterizing part of
Die erfindungsgemäße Lösung realisiert eine Lageerkennung des Bogens vor der Ausrichtung in Seitenrichtung, wenn der Bogen an den Vordermarken anliegt und der Vorausgehende vom Vorgreifer in die Anlegerdruckeinheit eingezogen wird. Der auszurichtende Bogen ist für kurze Zeit nicht mehr vom Vorausgehenden verdeckt und der Nachfolgende hat die Seitenzieheinrichtung noch nicht erreicht. In diesem freien Bereich ist die Abtasteinrichtung zur Lageerkennung des Bogens angeordnet. Ausgehend von seiner Ankunftslage wird jeder Bogen mittels der ziehwegabhängigen Unterdrucksteuerung nur solange mit Saugluft beaufschlagt, wie seine individuelle Abweichung von der Endlage es erfordert. Die Bewegung des Saugers bleibt dabei bei jedem Bogen konstant. Es wird bei geringeren als auch bei hohen Maschinengeschwindigkeiten (größer als 12.000 Bogen/h) eine paßgerechte Endlage des Bogens erzielt. Die Aufprallgeschwindigkeit des Bogens am Seitenanschlag wird definiert gesteuert, so daß ein Rückprallen des Bogens an den Vordermarken beseitigt wird. Unabhängig von der Maschinengeschwindigkeit und vom Zeitpunkt der Saugluftbeaufschlagung wird jeder Bogen vor der Ankunft am Seitenmarkenanschlag gleich verzögert und mit einer sehr kleinen Geschwindigkeit gegen den Anschlag bewegt. Dies wird über ein definiertes Wegzeitverhalten der Steuerkurve, in Kombination mit der individuellen, ziehwegabhängigen Unterdrucksteuerung, erzielt. Unabhängig von der Papiersorte werden dadurch auch die Bogenkanten geschont.The solution according to the invention realizes a position detection of the sheet before the alignment in the lateral direction when the sheet lies against the front marks and the preceding one is drawn into the feeder printing unit by the pre-gripper. The sheet to be aligned is for a short time no longer covered by the preceding one and the following one has not yet reached the side pulling device. The scanning device for detecting the position of the sheet is arranged in this free area. Starting from its arrival position, each sheet is only subjected to suction air by means of the vacuum path-dependent vacuum control as long as its individual deviation from the end position requires it. The movement of the suction cup remains constant with every curve. A correct end position of the sheet is achieved at both lower and higher machine speeds (greater than 12,000 sheets / h). The speed of impact of the sheet at the side stop is controlled in a defined manner so that a rebound of the sheet at the front marks is eliminated. Regardless of the machine speed and the time at which the suction air is applied, each sheet is immediately delayed before it arrives at the side mark stop and is moved against the stop at a very low speed. This is achieved via a defined travel time behavior of the control curve, in combination with the individual vacuum path control depending on the travel path. Regardless of the type of paper, this also protects the sheet edges.

Die erfindungsgemäße Lösung besteht aus einer in einem Anlegetisch 1 integrierten, pneumatischen Seitenzieheinrichtung und einem schaltungstechnisch mit ihr verbundenen Sensor 4 zur Lageerkennung eines Bogens 2. Der Sensor 4 ist in Bogenförderrichtung 21 gesehen vor dem auf einem Deckblech 8 befestigten Seitenanschlag 6 im Anlegetisch 1 fixiert. Sensor 4 und Seitenanschlag 6 sind dabei auf einer Linie 22 angeordnet und der Sensor 4 ragt mit seinem Meßbereich, ausgehend von der Linie 22, in den Bereich des Anlegetisches 1 hinein. Der Meßbereich des Sensors 4 ist dabei so groß wie der Bewegungsbereich eines Saugers 7. Die Seitenzieheinrichtung besteht aus einem Ventilgehäuse 10, in dem eine Antriebswelle 9 mittels Radiallager 18 aufgenommen ist. Auf der Antriebswelle 9 ist eine Steuerkurve 15 befestigt an der eine Rolle 23 abläuft. Die Rolle 23 ist mit einem auf einem parallel zur Antriebswelle 9 im Ventilgehäuse angeordneten Saugrohr 13 verschiebbar gelagerten Schlitten 14 verbunden. Der Schlitten 14 trägt den auswechselbaren Sauger 7 mit seiner Saugfläche 7.1. Im Bewegungsbereich des Schlittens 14 ist im Saugrohr 13 ein Durchbruch 12, der die Ansaugung der Luft über den Sauger 7 gewährleistet, vorgesehen. Der Sauger 7 ist in einer unter den Seitenanschlag 6 reichenden Ausnehmung 11 beweglich mit dem Schlitten 14 gekoppelt und in das Deckblech 8 integriert.The solution according to the invention consists of a pneumatic side pulling device integrated in a feed table 1 and a In terms of circuitry,
Das Ventilgehäuse 10 besitzt eine mit einer Saugpumpe 19 verbundene Saugluftleitung 16, die mit einem Magnetventil 17 gekoppelt ist. Das Magnetventil 17 ist mit dem Saugrohr 13 verbunden und weiterhin mit einem Signalwandler 5 schaltungstechnisch verbunden, der wiederum mit dem im Anlegetisch 1 fixierten Sensor 4 gekoppelt ist. Am freien Stirnende des Saugrohres 13 ist ein Ventil 20, z.B. ein Tellerventil, angeordnet. Dieses Ventil 20 ist schaltungstechnisch mit einem Endlagenschalter 24 verbunden der am Ventilgehäuse 10 angeordnet ist und mittels Saugschlitten 14 kontaktiert wird, wenn dieser seine hintere Endlage erreicht hat.The
Die Wirkungsweise der Anordnung wird nachfolgend beschrieben. Die vom Anlageapparat vereinzelten Bogen 2 werden den Vordermarken 3 über den schräg angeordneten Anlegetisch 1, z.B. einem Saugbändertisch, zugeführt. Bogen 2 liegt nun an den Vordermarken 3 an und der Vorausgehende wird vom Vorgreifer in die Anlegerdruckeinheit eingezogen. Bogen 2 ist somit nicht mehr vom Vorausgehenden verdeckt und der Nachfolgende hat die Seitenzieheinrichtung noch nicht erreicht. In diesem Bereich ist der Sensor 4, z.B. ein Reflexionsmeßkopf, zur Lageerkennung des Bogens 2 im Anlegetisch 1 fixiert. Sensor 4 ermittelt nun den individuellen Ziehweg für den Bogen 2. Diese Information wird schaltungstechnisch über den Signalwandler 5 dem Magnetventil 17 zugeführt. Am Magnetventil 17 liegt ständig ein von der Saugpumpe 19 erzeugter und über die Saugluftleitung 16 zugeführter Unterdruck an. Der Sauger 7 befindet sich in einer Stellung, die dem hohen Punkt der Steuerkurve 15 entspricht. Während der Bogen 2 an den Vordermarken 3 anliegt, wird der Sauger 7, ausgehend von der im Takt der ankommenden Bogen 2 arbeitenden Antriebswelle 9, der Steuerkurve 15, Rolle 23 und dem auf dem Saugrohr 13 verschiebbaren Saugschlitten 14 zum Seitenanschlag 6 bewegt. Je nach vom Sensor 4 ermittelter Lage und daraus resultierenden individuellem Ziehweg des Bogens 2 wird die Saugluft über das Magnetventil 17 früher oder später zur konstant ablaufenden Bewegung des Saugers 7 dazu geschaltet. Jeder Bogen 2 wird vom Sauger 7 lagefixiert gegen den Seitenanschlag 6 gefördert. Am Ventilgehäuse 10 wird der Endlagenschalter 24 vom Schlitten 14 kontaktiert und bewirkt das Öffnen des Ventils 20. Der Unterdruck bricht somit schnell zusammen. Die Haltekraft zwischen Sauger 7 und Bogen 2 ist so bemessen, daß der Sauger 7 unter dem Bogen 2 hindurch rutscht, wenn dieser am Seitenanschlag anliegt und schließlich freigegeben wird (hintere Endlage). Dies wird durch eine Verzögerungsphase im Wegzeitverhalten der Steuerkurve 15 und durch das am freien Ende des Saugrohres 13 angeordnete, jetzt geöffnete Ventil 20 realisiert.The operation of the arrangement is described below. The
