The carrying bars (7) of an auxiliary carrier (3) are moved in the pallet slots, for the receiving of the stack (S) or the residual stack (R). Following the placing of the pallet on the stack carrying plate, the position of at least one slot on the top side of the pallet in the direction of the A or B sides is detected and before the travelling in of the carrier bars in the slots of the pallet, the carrier bars are aligned corresp. to the established position in the direction of the A or B sides.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Ausrichtung eines automatischen Stapelwechslers gemäß dem Oberbegriff des Verfahrens- bzw. Vorrichtungsanspruches.The invention relates to a method and a device for aligning a automatic stack changer according to the preamble of the process or Device claim.

Bei Bogenoffsetdruckmaschinen werden die zu bedruckenden Bogen von der Oberseite eines Anlegerstapels entnommen und über einen Fördertisch zu einer Anlage transportiert. Da bei Bogenoffsetdruckmaschinen Bedruckstoffstärken in der Größenordnung von 1mm und mehr verarbeitet und auch mit einer hohen Druckgeschwindigkeit durch die Maschine gefördert werden (10.000 bis 15.000 Bogen/h), sind die Stapel im Anleger der Maschine relativ schnell abgearbeitet. Um den Auflagedruck ohne Unterbrechung fortführen zu können, ist es nötig, einen neuen Stapel auf der Stapeltragplatte bereitzustellen, d.h diesen neuen Stapel genau in der gleichen Position unterhalb des Reststapels (vorheriger abgearbeiteter Stapel) zu positionieren und sodann den Reststapel mit dem neuen Hauptstapel zu vereinigen. Zu diesem Zweck sind automatische Stapelwechselvorrichtungen entwickelt worden, vermittels denen der bis auf einen Rest abgearbeiteter Stapel (Reststapel) von der Palette auf der Stapeltragplatte abgenommen und nach dem Absenken der Stapeltragplatte sowie dem Aufsetzen eines neuen Hauptstapels wieder lagegenau auf der Oberseite eines neuen Hauptstapels aufgelegt werden kann. Diese bekannten Stapelwechselvorrichtungen arbeiten insbesondere mit horizontal verfahrbaren Stäben nach Art eines Rechens zusammen, wobei diese den Reststapel aufnehmenden Stäbe an einer vertikal verfahrbaren Hilfsstapeltragvorrichtung angebracht sind. In sheetfed offset printing machines, the sheets to be printed are printed by the Removed the top of a feeder stack and a conveyor table to one Plant transported. With sheetfed offset printing presses in the order of 1mm and more processed and also with a high Printing speed can be conveyed through the machine (10,000 to 15,000 Sheets / h), the stacks in the feeder of the machine are processed relatively quickly. In order to continue printing without interruption, it is necessary to provide a new stack on the stack support plate, i.e. this new one Stack exactly in the same position below the remaining stack (previously processed Stack) and then position the remaining stack with the new one Unite main stack. Automatic stack changing devices are for this purpose have been developed, by means of those which have been processed to the rest Stack (residual stack) removed from the pallet on the stack support plate and after lowering the stack support plate and putting on a new one Main stack again placed exactly on top of a new main stack can be. These known stack changing devices work in particular together with horizontally movable bars in the manner of a rake, wherein these rods receiving the remaining stack on a vertically movable Auxiliary stack support device are attached.

Die nicht vorveröffentlichte DE 197 04 285 A1 zeigt eine derartige Stapelwechseleinrichtung für den Bogenanleger einer Bogenoffsetdruckmaschine, bei welcher die Stäbe der Hilfsstapeltragvorrichtung einzeln und/oder in Gruppen zusammengefaßt zum Abheben des Reststapels einfahrbar ausgebildet sind. Die die Stapel aufnehmenden Paletten weisen an deren Oberseite ein Nutprofil auf, wobei die Nuten in Richtung der ein- und ausfahrbar gelagerten Stäbe verlaufen. Die Hilfsstapeltragvorrichtung wird in einem derartigen Höhenniveau positioniert, daß die Stäbe genau in der Höhe der Nuten zwischen den den Stapel tragenden Stegen eintauchen können. Zu diesem Zweck ist es nötig, nach dem Absenken der Stapeltragplatte mit Aufsetzen einer neuen Palette diese Palette mit dem neuen Stapel genau zu den Stäben der Hilfsstapeltragvorrichtung auszurichten. Geschieht dies nicht, so kann es zu einer Kollision der Stäbe mit den Stegen der Palette (Nutprofil) und somit zu erheblichen Beschädigungen kommen.The unpublished DE 197 04 285 A1 shows such a stack changing device for the sheet feeder of a sheetfed offset press, at which combines the rods of the auxiliary stack support device individually and / or in groups are designed to be retractable for lifting off the remaining stack. The the stack-receiving pallets have a groove profile on their top, the grooves run in the direction of the retractable and extendable rods. The auxiliary stack support device is positioned at such a height level that the bars are exactly at the level of the grooves between those carrying the stack Can immerse webs. For this purpose it is necessary after lowering the stack support plate with a new pallet, this pallet with the Align the new stack precisely with the bars of the auxiliary stack support device. If this does not happen, the rods may collide with the webs of the Pallet (groove profile) and thus considerable damage.

Eine einfache Ausrichtmöglichkeit ergibt sich dadurch, daß die auf die abgesenkte Stapeltragplatte aufzusetzende neue Palette mit dem darauf befindlichen Stapel exakt in eine vorgegebene Position verbracht wird, also durch die Bedienperson mittels Hubwagen genau an dem dafür vorgesehenen Platz abgestellt werden muß. Dies macht die Handhabung relativ zeitaufwendig und umständlich, ferner verlängert sich dadurch die für den gesamten Stapelwechselvorgang zur Verfügung stehende Zeit, so daß insgesamt größere Reststapel von der Hilfsstapeltragvorrichtung aufzunehmen sind und die Häufigkeit der automatischen Stapelwechsel sich erhöht.A simple alignment option results from the fact that the lowered on the Stacking pallet new pallet to be placed with the one on it Stack is brought exactly into a predetermined position, that is, by the operator parked exactly in the space provided for this using a pallet truck must become. This makes handling relatively time consuming and cumbersome furthermore, this extends the entire stack changing process Time available so that overall larger residual stacks from the auxiliary stack support device are included and the frequency of automatic Stack change increases.

Aus der US-PS 5 011 126 ist es bekannt den unterhalb des Hilfsstapels neu aufgestellten Hauptstapel mittels einer seitlich hin- und herverfahrbaren Stapeltragplatte derartig zu positionieren, so daß der Reststapel genau deckungsgleich auf der Oberseite des neuen Hauptstapels zu liegen kommt. Dazu sind Detektoren vorgesehen, vermittels denen die Lage des Reststapels (Seitenfläche des Reststapels) sowie des darunter befindlichen Hauptstapels tastbar ist. Diese vorbekannte Einrichtung weist jedoch nicht Tragstäbe einer Hilfsstapeltragvorrichtung auf, welche mit einem auf der Oberseite einer Palette angeordneten Nutprofil zusammenwirken.From US-PS 5 011 126 it is known the newly set up below the auxiliary stack Main stack by means of a stack support plate that can be moved back and forth to be positioned in such a way that the remaining stack is exactly congruent the top of the new main stack. There are detectors provided, by means of which the position of the remaining stack (side surface of the remaining stack) and the main stack underneath is palpable. This previously known However, the device does not have support rods of an auxiliary stack support device which cooperate with a groove profile arranged on the top of a pallet.

Aus der DE 4 129 702 C2 ist ein Entfernungsmeßsystem bekannt, welches insbesondere dem speziellen Anwendungsfall der Stapelausrichtung bei einem automatischen Stapelwechsler dient. Dieses System besteht aus zwei nach dem Triangulationsprinzip arbeitenden Meßkanälen, durch welche jeweils der Abstand zur Seitenfläche des Reststapels bzw. der des Hauptstapels erfaßbar ist, um diese Stapel dann über entsprechende Positioniereinrichtungen relativ zueinander auszurichten. Mit diesem speziellen Meßwertsystem gelingt jedoch keine Ausrichtung einer Hilfsstapeltrageinrichtung mit horizontal verfahrbaren Stäben relativ zu einer auf der Oberseite ein Nutprofil aufweisenden Palette.A distance measuring system is known from DE 4 129 702 C2, which in particular the special application of stack alignment in an automatic Stack changer is used. This system consists of two after the Triangulation principle working measuring channels, through which the distance to the side surface of the remaining stack or that of the main stack is detectable in order to these stacks then relative to one another via corresponding positioning devices align. With this special measurement system, however, no one succeeds Alignment of an auxiliary stack support device with horizontally movable bars relative to a pallet with a groove profile on the top.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren und eine Vorrichtung zur Ausrichtung eines automatischen Stapelwechslers gemäß dem Oberbegriff des Verfahrens- bzw. Vorrichtungsanspruches derartig zu erweitern, so daß unter Vermeidung der zuvorstehend genannten Nachteile eine einfache und sichere Positionierung der Stäbe der Hilfsstapeltragvorrichtung zu der entsprechend strukturierten Oberfläche der den Hauptstapel aufnehmenden Paletten gewährleistet ist.The object of the present invention is therefore a method and a device to align an automatic stack changer according to the generic term to expand the process or device claim in such a way, so that while avoiding the disadvantages mentioned above, a simple and safe positioning of the bars of the auxiliary stack support device to the corresponding structured surface of the pallets receiving the main stack is guaranteed.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Verfahrens- bzw. des Vorrichtungsanspruches. Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.This task is solved by the characteristic features of the process or of the device claim. Further developments of the invention result from the respective subclaims.

Gemäß der Erfindung ist vorgesehen, daß nach Aufsetzen einer neuen Palette auf die vollständig bzw. fast vollständig abgesenkte Stapeltragplatte für den Hauptstapel die Lage dieser neuen Palette dahingehend sensorisch erfaßt wird, um festzustellen, um welchen Wegbetrag in Richtung A- bzw. B-Seite die Stäbe der Hilfsstapeltragvorrichtung verfahren werden müssen, um genau in die Nuten zwischen den Stegen an der Oberseite der Palette eintauchen zu können. According to the invention it is provided that after putting on a new pallet on the completely or almost completely lowered stack support plate for the Main stack, the position of this new pallet is sensed, to determine the amount of travel towards the A or B side of the bars The auxiliary stack support device must be moved precisely into the grooves to be able to dip between the webs on the top of the pallet.

Erfindungsgemäß gelingt dies in einer ersten bevorzugten Ausführungsform dadurch, daß im unteren Bereich des Anlegers ein als Reflektionslichttaster ausgebildeter Sensor angeordnet ist, vermittels dem die seitliche Orientierung der Palette bzw. des Nutprofils mit darauf befindlichem Hauptstapel auf der Stapeltragplatte feststellbar ist. Dieser Reflektionslichttaster ist dabei in einer derartigen Höhe im unteren Bereich des Anlegers, vorzugsweise in dessen Mitte angeordnet, so daß nach dem Aufsetzen einer neuen Palette nebst auf deren Oberseite befindlichen Stapel und dem Anheben der Stapeltragplatte um einen vorbestimmten wegbetrag der wirksame Tastbereich genau auf der Höhe des Nutprofils der Palette liegt. Sodann wird die Stapeltragplatte um vorgegebene Wegbeträge in Richtung A- und/oder B-Seite verfahren, daß aufgrund der Tastsignale des Sensors die Lage der Nuten bzw. der dazwischen liegenden Stege feststellbar ist. Zur Feststellung der Lage einer Nut kann es ausreichend sein, die Stapeltragplatte lediglich in eine Richtung zu verfahren (z.B. A-Seite), um aus dem Signalwechsel des Sensors die Position der Nut zu bestimmen. Eine höhere Genauigkeit ergibt sich aber dann, wenn die Stapeltragplatte um vorgegebene Wegbeträge in beide Richtungen verfahren wird und so aus dem Signalverlauf des Sensors in Verbindung mit den Steuersignalen für den Pos-Antrieb der Stapeltragplatte die Mitte einer Nut bestimmt wird.According to the invention, this is achieved in a first preferred embodiment by that in the lower area of the feeder is designed as a reflection light sensor Sensor is arranged by means of the lateral orientation of the pallet or the groove profile with the main stack on the stack support plate is noticeable. This reflection light scanner is one of these Height in the lower area of the feeder, preferably arranged in the middle thereof, so that after placing a new pallet on top of it located stack and lifting the stack support plate by a predetermined the effective sensing range exactly at the height of the groove profile the pallet lies. Then the stack support plate by predetermined travel amounts move in the direction of the A and / or B side, that due to the key signals the position of the grooves or the webs between them can be determined by the sensor is. To determine the position of a groove, it may be sufficient to use the stack support plate only move in one direction (e.g. A-side) to get out of the Signal change of the sensor to determine the position of the groove. A higher accuracy results, however, when the stack support plate by predetermined travel amounts is moved in both directions and thus from the signal curve of the Sensors in connection with the control signals for the pos drive of the stack support plate the center of a groove is determined.

Nach dem Bestimmen der Lage einer Nut kann die Stapeltragplatte wieder in die Grundposition (Mitte Anleger) verfahren werden. Aus der Lage wenigstens einer Nut bzw. eines Steges ist dann ermittelbar, um wieviel die Stäbe bzw. die ganze Hilfsstapeltragvorrichtung in Richtung A- bzw. B-Seite verfahren werden muß (ausgehend von einer Null-Stellung), damit zum Abnehmen des Reststapels die Stäbe genau in die Nuten der Palette einfahren können. In dieser von der Lage der Palette auf der Stapeltragplatte abhängigen Position verbleiben die Tragstäbe dann bis zu einem erneuten Einfahren, also bis wieder eine neue Palette mit neuem Stapel aufgesetzt wird. Nach Abheben des Reststapels von der Palette wird der neue Hauptstapel durch seitliche Ausrichtbewegungen in eine zum Reststapel deckungsgleiche Position verbracht, wozu die Seitenflanken des Rest- und Hauptstapels tastende Detektoren vorgesehen sind.After determining the position of a groove, the stacking support plate can be put back into the Basic position (middle of feeder). From the situation at least one Groove or a web can then be determined by how much the bars or the whole Auxiliary stack support device must be moved in the direction of the A or B side (starting from a zero position), so that to remove the remaining stack Can insert rods precisely into the grooves of the pallet. In this from the location The support rods remain in the pallet on the position dependent on the stack support plate then until a new run-in, i.e. until a new pallet with new stack is put on. After removing the remaining stack from the pallet the new main stack is turned into one by lateral alignment movements Remaining stack spent congruent position, for which the side edges of the rest and Main stack scanning detectors are provided.

Gemäß der zuvorstehend beschriebenen ersten bevorzugten Ausführungsform der Erfindung erfolgt die Palettenausmessung durch einen im unteren Bereich des Anlegers angeordneten Sensor (Reflexlichttaster). Mit diesem Sensor, der mit der Oberseite der Palette im Bereich des Nutprofiles zusammenwirkt, ist wegen der Periodizität des Nutprofiles die Mindestverschiebung der Tragstäbe der Hilfsstapeltragvorrichtung bestimmbar, damit diese kollisionsfrei in den zwischen den Tragstegen befindlichen Nuten der Oberseite der Palette eintauchen können. Ferner ist durch diesen einen Sensor auch feststellbar, ob die Palette in einer richtigen Orientierung zur Stapeltragplatte aufgesetzt worden ist, also insbesondere ob die Kante der Palette parallel bzw. hinreichend parallel zu einer entsprechenden Ausrichtkante der Stapeltragplatte verläuft. Letztlich ist durch diesen einen Sensor auch feststellbar, ob überhaupt der richtige Palettentyp verwendet worden ist, also eine Palette, welche auf ihrer Oberseite das auszumessende Nutprofil aufweist. Somit wäre bei Verwendung einer Palette ohne jegliches Nutprofil auf der Oberseite durch das erfindungsgemäß vorgesehene Ausmessen der Stapeltragplatte kein Wechsel des Tastsignals beim Verfahren der Palette feststellbar.According to the first preferred embodiment described above According to the invention, the pallet is measured by a in the lower area of the Sensor arranged by the investor (diffuse sensor). With this sensor, the one with the Interaction of the top of the pallet in the area of the groove profile is due to the Periodicity of the groove profile the minimum displacement of the support rods of the auxiliary stack support device can be determined so that they collision-free in the between the Grooves located on the top of the pallet can dip. Furthermore, this one sensor can also determine whether the pallet is in one correct orientation to the stack support plate has been placed, in particular whether the edge of the pallet is parallel or sufficiently parallel to a corresponding one Aligning edge of the stack support plate runs. Ultimately, through this a sensor can also determine whether the correct pallet type is used at all a pallet, which has the one to be measured on its top Has groove profile. This would be without any groove profile when using a pallet on the top by measuring the Stack support plate no change of the tactile signal detectable when moving the pallet.

Gemäß einer Weiterbildung der Erfindung kann vorgesehen sein, daß die Orientierung der auf die Stapeltragplatte aufgesetzten Palette mittels zwei voneinander beabstandenden Sensoren erfolgt. Auch in diesem Fall wird dann aus dem entsprechenden Verfahrsignal des Antriebs der seitlichen Positioniereinrichtung der Stapeltragplatte in Verbindung mit den Signalen der Sensoren der Wegbetrag bestimmt, um welchen die Stäbe bzw. die gesamte Hilfsstapeltragvorrichtung mit den darin enthaltenen Stäben in Richtung A- bzw. B-Seite zu verfahren sind.According to a development of the invention, it can be provided that the orientation the pallet placed on the stack support plate by means of two of them spacing sensors. In this case, too, the corresponding Travel signal of the drive of the lateral positioning device Stack support plate in connection with the signals from the sensors the travel amount determines by which the bars or the entire auxiliary stack support device with the rods contained in it must be moved in the direction of the A or B side.

Nachdem das erfindungsgemäß vorgesehene Ausmessen der Lage der auf der Stapeltragplatte befindlichen Palette durch seitliches Verfahren der Tragplatte abgeschlossen ist, kann gemäß einer bevorzugten Ausführungsform der Erfindung die Stapeltragplatte des Hauptstapels wieder in die Null-Position zurückgefahren werden, um dann über die Stapeltragplatte seitlich so ausgerichtet zu werden, daß die Seitenflanken des Hauptstapels mit den durch die Tragstäbe der Hilfsstapeltragvorrichtung gehaltenen Reststapels zusammenfallen (fluchten). Dann erfolgt das Vereinigen von Reststapel mit neuem Hauptstapel durch Herausziehen der Stäbe der Hilfsstapeltragvorrichtung.After the measurement of the position on the Pallet support plate located pallet by lateral movement of the support plate is completed, according to a preferred embodiment of the invention the stack support plate of the main stack is moved back to the zero position are then aligned laterally over the stack support plate be that the side edges of the main stack with the through the support rods of the Auxiliary stack support device collapsed remaining stack (align). Then the remaining stack is combined with the new main stack by pulling out the bars of the auxiliary stack support.

Nachdem die Tragstäbe zwischen Palette und neuem Hauptstapel eingefahren worden sind, bewegen sich die Stapeltragplatte und die Hilfsstapeltragvorrichtung solange synchron, d.h. die entsprechenden Antriebe werden durch die sensorische Stapeloberkantentastung solange synchron verfahren, bis der Reststapel eine vorgesehene Mindesthöhe erreicht hat, woraufhin dann die Stapeltragplatte abgesenkt und zum Beladen mit einer neuen Palette nebst Hauptstapel in eine Grundposition am Boden verfahren wird. Nach Aufsetzen eines neuen Stapels nebst Palette erfolgt dann wiederum das Ausmessen der Lage der Palette, um die Tragstäbe kollisionsfrei in die Nuten an der Oberseite der Palette einfahren zu können.After the support rods between the pallet and the new main stack are retracted the stack support plate and the auxiliary stack support device move as long as synchronous, i.e. the corresponding drives are sensory Move the top edge of the stack synchronously until the remaining stack has reached an intended minimum height, whereupon the stack support plate lowered and loaded into a new pallet together with the main stack Basic position is moved on the ground. After placing a new stack In addition to the pallet, the position of the pallet is then measured around the Insert the support rods into the grooves on the top of the pallet without collision can.

Einer Bogenoffsetdruckmaschine 1 werden von einem Anleger 2 über einen dazwischen befindlichen Fördertisch Bogen zugeführt. Im Anleger 2 werden dazu mittels Bogenvereinzelungsvorrichtungen 4 Bogen von der Oberseite eines Stapels S entnommen (Fig. 1). Der Hauptstapel S im Anleger 2 ist mittels einer Palette P auf einer über eine nicht dargestellte Hubvorrichtung heb- und senkbare Stapeltragplatte ST aufgestellt. Dem Anleger 2 ist ein Hilfsstapelträger 3 vorgeordnet, der über Führungsschienen 8 einer Hubvorrichtung 5 heb- und senkbar ist. Der Hilfsstapelträger 3 weist ein Gestell 6 auf, in dem horizontal verfahrbare Tragstäbe 7 angeordnet sind, welche sich in der Darstellung gemäß Fig. 1 in der eingefahrenen Position innerhalb des Gestelles 6 befinden.A sheetfed offset printing machine 1 is fed by a feeder 2 in between located conveyor table arch fed. This will be done in investor 2 4 sheets from the top of a stack by means of sheet separation devices S taken (Fig. 1). The main stack S in the feeder 2 is by means of a pallet P on a lifting device, not shown, can be raised and lowered Stacking support plate ST set up. An auxiliary stack carrier 3 is arranged upstream of the feeder 2, which can be raised and lowered via guide rails 8 of a lifting device 5 is. The auxiliary stack carrier 3 has a frame 6, in which horizontally movable Support rods 7 are arranged, which in the illustration according to FIG. 1 in the retracted position are within the frame 6.

Die auf der Stapeltragplatte ST den Hauptstapel S aufnehmenden Paletten P weisen an deren Oberseite eine Vielzahl parallel zueinander verlaufende Nuten N mit jeweils dazwischen verbleibenden und die Unterseite des Hauptstapels S tragenden Stegen SG auf (Fig. 5). Der Abstand und die Breite der Nuten N sowie entsprechend die Breite der dazwischenliegenden den Stapel tragenden Stege SG ist auf den Abstand und die Breite der Tragstäbe 7 des Hilfsstapelträgers 3 abgestimmt.The pallets P receiving the main stack S on the stack support plate ST have a plurality of grooves N running parallel to one another on the upper side thereof with each remaining in between and bearing the underside of the main stack S. Web SG on (Fig. 5). The distance and width of the grooves N as well correspondingly the width of the intermediate webs carrying the stack SG is on the distance and the width of the support rods 7 of the auxiliary stack carrier 3rd Voted.

Die Figuren 3 und 4 zeigen den durch die Tragstäbe 7 des Hilfsstapelträgers 3 gehaltenen Reststapel 1 oberhalb des Hauptstapels S. Zunächst wurde in der untersten Position der Stapeltragplatte ST ein neuer Stapel S mit einer Palette P aufgestellt. Danach ist die Stapeltragplatte ST in eine vorgegebene Höhenposition oberhalb der Grundposition verfahren worden, so daß durch einen im unteren Bereich des Anlegers 2 angeordneten Sensor 9, der als optischer Reflexlichttaster (Entfernungsmeßsystem) ausgebildet ist, das Profil der Nuten N und der dazwischenliegenden Stege SG dem Wirkbereich des Sensors 9 gegenüberliegt. Daraufhin wird über die Steuerung 11 für den automatischen Stapelwechsel der Antrieb 10 für die Seitenausrichtung der Stapeltragplatte ST derartig angesteuert, so daß die Stapeltragplatte ST um einen vorgegebenen Wegbetrag in Richtung A- und/oder B-Seite verfahren wird. Dabei ist durch den als Reflexlichttaster ausgebildeten Sensor 9 feststellbar, bei welchem Verfahrweg des als Positionierantrieb ausgebildeten Antriebes 10 eine Kante des Übergangs zwischen Nut N und Steg SG der Palette P auftritt, also um welchen Wegbetrag die Palette P über die Stapeltragplatte ST zu verschieden ist, damit der genau in der Formatmitte des Anlegers 2 angeordnete Sensor 9 einer Nut N der Palette P gegenüberliegt. Dieser beim Flankenwechsel des Ausgangssignales des Sensors 9 vorliegende Verschiebeweg wird durch die Steuerung 11 erfaßt und gespeichert. Die Stapeltragplatte ST weist zusätzliche Einrichtungen und Markierungen auf (nicht dargestellt), vermittels denen eine Palette P mit darauf befindlichem Stapel S zumindest annähernd in der Mitte der Stapeltragplatte ST und somit des Anlegers 2 aufstellbar ist.Figures 3 and 4 show the through the support rods 7 of the auxiliary stack carrier 3rd held remaining stack 1 above the main stack S. First in the lowest position of the stack support plate ST a new stack S with a pallet P set up. The stack support plate ST is then in a predetermined height position have been moved above the basic position, so that by an im lower region of the feeder 2 arranged sensor 9, which acts as an optical diffuse sensor (Distance measuring system) is formed, the profile of the grooves N and the webs SG lying therebetween are opposite the effective range of the sensor 9. Thereupon the control 11 for the automatic stack change the drive 10 for the side alignment of the stack support plate ST is controlled in this way, so that the stack support plate ST in by a predetermined amount Is moved towards the A and / or B side. It is by the as a diffuse sensor trained sensor 9 can be determined at which travel of the as a positioning drive trained drive 10 an edge of the transition between Groove N and web SG of the pallet P occur, i.e. the amount by which the pallet P on the stacking support plate ST is too different so that it is exactly in the middle of the format the sensor 2 arranged sensor 9 of a groove N of the pallet P is opposite. This is present when the edge of the output signal of sensor 9 changes Displacement is detected and stored by the controller 11. The Stack support plate ST has additional facilities and markings (not shown), by means of which a pallet P with a stack S thereon at least approximately in the middle of the stack support plate ST and thus the feeder 2 can be set up.

Nachdem durch die Steuerung 11 der über den Antrieb 10 für die Seitenausrichtung der Stapeltragplatte ST nötige Weg zur Lageerfassung wenigstens einer Nut N durch den Sensor 9 bestimmt worden ist, werden die über einen weiteren Positionierantrieb 12 in Richtung A- und B-Seite verfahrbar gelagerten Tragstäbe 7 des Hilfsstapelträgers 3 entsprechend ausgerichtet, so daß diese, nachdem der Hilfsstapelträger 3 auf das Höhenniveau zum Einfahren der Stäbe unter den Stapel S bewegt wurde, in die Nuten N der Palette P einfahren können.After through the controller 11 of the drive 10 for the side alignment the stack support plate ST necessary way to detect the position of at least one groove N has been determined by the sensor 9, the are via a further positioning drive 12 support rods 7 which can be moved in the direction of the A and B sides of the auxiliary stack carrier 3 aligned accordingly, so that after the Auxiliary stack carrier 3 to the height level for moving the bars under the stack S has been moved into the grooves N of the pallet P.

Das seitliche Verfahren der Palette P, der Stapeltragplatte ST sowie des Stapels S zur Bestimmung der nötigen Orientierung der Tragstäbe 7 des Hilfsstapelträgers 3 ist zusätzlich noch einmal in Fig. 2 in einer Ansicht von oben dargestellt. An dieser Stelle sei noch einmal darauf hingewiesen, daß vor Ausführen des seitlichen Verfahrens der Stapeltragplatte ST durch den Antrieb 10 zur Lageerfassung wenigstens einer Nut N die Stapeltragplatte ST sich in einer Grundstellung in der Mitte des Anlegers 2 befindet. Nach dem Ausmessen der Palette P kann die Stapeltragplatte ebenfalls wieder in die Grundstellung verfahren werden. Auch die Tragstäbe 7 des Hilfsstapelträgers 3 befinden sich vor der seitlichen Ausrichtung entsprechend der durch den Sensor 9 festgestellten nötigen Verschiebung in einer Grundposition (Null-Stellung). Erst zum Einfahren der Tragstäbe 7 werden diese bzw. der Hilfsstapelträger seitlich ausgerichtet, wobei diese Position nach dem Abheben des Reststapels R von der Palette P bis zu Vereinigung mit einem neuen Stapel S durch Herausziehen der Tragstäbe 7 beibehalten wird. Dadurch bleiben die durch die Bogenvereinzellung 4 von der Oberseite des Haupt- bzw. Reststapels S, R abzunehmenden Bogen stets in der gleichen Orientierung zum Seitenregister.The lateral movement of the pallet P, the stack support plate ST and the stack S to determine the necessary orientation of the support rods 7 of the auxiliary stack carrier 3 is additionally shown again in FIG. 2 in a view from above. At this point it should be pointed out again that before executing the lateral Method of the stack support plate ST by the drive 10 for position detection at least one groove N the stack support plate ST in a basic position is located in the middle of the feeder 2. After measuring the pallet P can the stack support plate can also be moved back to the basic position. Also the support rods 7 of the auxiliary stack carrier 3 are in front of the lateral alignment corresponding to the necessary shift in detected by the sensor 9 a basic position (zero position). Only to retract the support rods 7 this or the auxiliary stack carrier aligned laterally, this position after the removal of the remaining stack R from the pallet P until it is combined with one new stack S is maintained by pulling out the support rods 7. Thereby remain through the arches 4 from the top of the main or Remaining stack S, R sheets to be removed always in the same orientation to Page register.

Abschließend sei festgestellt, daß durch den Antrieb 10 für die Seitenausrichtung der Stapeltragplatte ST neben der zuvorstehend erfindungsgemäßen Ausmessung der Lage der Nuten N/Stege SG der Palette P auch die Seitenausrichtung des Stapel S vor der Vereinigung mit dem Reststapel R erfolgt. Jeder neu aufgesetzte Stapel S wird somit individuell bezüglich dem durch die Tragstäbe gehaltenen Reststapel R ausgerichtet. Finally, it should be noted that the drive 10 for the side alignment the stack support plate ST in addition to the measurement according to the invention described above the position of the grooves N / webs SG of the pallet P also the side orientation of the stack S takes place before the union with the remaining stack R. Every new one Stack S is thus individual with respect to that held by the support rods Remaining stack R aligned.
