Abstract

An approximately vertical stack (1) of flat sheets of paper stands on a lifting jack ready for removal from the top one sheet at a time by e.g. a suction device serving e.g. a print machine. The exact position of the stack side is ascertained by a sensor which consists of a touch-wheel (6) on an arm (7) linked to a switch (9) and held in position by a spring (14). As the stack is raised the sensor wheel defines the position of the stack edge to within a fine tolerance. The exact position of the stack can then be adjusted for precision pick-up of the top sheet of paper. The sensor is non-linear.

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

In bogenverarbeitenden Maschinen sind zur Vereinzelung von Bögen von einem Anlegerstapel Vorrichtungen vorgesehen, die eine exakte Trennung von Einzelbögen und deren genauen Transport zur bogenverarbeitenden Maschine erlauben. In einem Bogenanleger sind dazu ein Hubwerk, ein sogenannter Saugkopf und Ausrichtvorrichtungen für den Stapel bzw. die Bögen vorhanden. Dabei kommt es darauf an, daß die Bogen innerhalb einer gewissen Toleranzbreite in ihrer seitlichen Lage quer zur Transportrichtung geführt werden. Der Einfluß dieser Lage auf die Funktionsweise in der bogenverarbeitenden Maschine ist groß. Die seitliche Lage der Bogen wird schon durch die möglichst korrekte Ausrichtung des im Bogenanleger zu verarbeitenden Bogenstapels bestimmt. Da die Bogenstapel im angelieferten Zustand nicht immer exakt ausgerichtet sind, sind im Anleger Mittel vorzusehen, um eventuelle Abweichungen während des Betriebes der bogenverarbeitenden Maschine ausgleichen zu können. Damit wird sichergestellt, daß die Bogen im Rahmen einer gewissen Toleranz zur bogenverarbeitenden Maschine angeliefert werden. Hierbei sind beispielsweise an den Stapelseitenkante Sn Abtasteinrichtungen vorgesehen, mittels derer Abweichungen der Bogenlage feststellbar und ausregulierbar sind. Die Abtasteinrichtungen liefern Signale, um innerhalb des Bogenanlegers Stapelbewegungen zu erzeugen. Dazu ist der Bogenstapel beispielsweise auf einer seitlich bewegbaren Stapeltragplatte angeordnet.In sheet processing machines are used to separate sheets from one Feeder stack devices are provided that provide an exact separation of Single sheets and their exact transport to the sheet processing machine allow. For this purpose, a hoist, a so-called Suction head and alignment devices for the stack or sheets available. It is important that the bend is within a certain tolerance range be guided in their lateral position transversely to the transport direction. The influence This location on how it works in the sheet processing machine is great. The lateral position of the arches is already correct alignment of the sheet stack to be processed in the sheet feeder. Since the Sheet stacks in the delivered state are not always exactly aligned, are in the Investors provide funds to cover any deviations during operation to be able to compensate for the sheet processing machine. So that will ensured that the bow within a certain tolerance sheet processing machine can be delivered. Here are for example the stack side edge Sn provided by means of which Deviations in the sheet position can be determined and adjusted. The Scanners deliver signals to within the sheet feeder Generate batch movements. For this purpose, the stack of sheets is open, for example a laterally movable stack support plate.

Beispielsweise ist in der DE-OS 2911735 ein Bogenanleger beschrieben. Der Bogenanleger weist ein Hubwerk auf, an dessen Tragplatte für einen Bogenstapel eine Ausrichtvorrichtung vorgesehen ist. Die Ausrichtvorrichtung wird durch einen Sensor, der auf eine obere seitliche Stapelkante einwirkt, angesteuert. Ein solcher Sensor ist in Form einer Tastrolle ausgebildet und einer oder beiden seitlichen Stapelkanten des Bogenstapels zugeordnet. Beim Anheben des Bogenstapels mittels des Hubwerkes gerät die seitliche Stapelkante in den Bereich der Tastrolle und beeinflußt diese in unterschiedlicher Weise. Die Tastrolle ist mittels Federkraft in Richtung der Stapelkante angestellt. Je nach Lage der Tastrolle kann mittels elektrischer Schalteinrichtungen eine Position der Stapelkante in einem bestimmten Toleranzbereich erfaßt werden. Damit wird die Sollage der Stapelkante definiert erkannt und kann mittels der Stelleinrichtungen an der Stapelplatte nachgefahren werden. Die gezeigte Sensoranordnung wirkt infolge ihrer Anordnung nicht linear. Die Abtastung von Kurvensegmenten wirkt sich auf die Toleranzen ungünstig aus.For example, a sheet feeder is described in DE-OS 2911735. The Sheet feeder has a hoist on its support plate for a sheet stack an alignment device is provided. The alignment device is a Sensor that acts on an upper side stack edge. Such a Sensor is designed in the form of a sensing roller and one or both sides Assigned stack edges of the sheet stack. When lifting the sheet stack by means of the lifting device, the side stack edge comes into the area of the feeler roller and influences them in different ways. The tracer roller is spring-loaded in the direction of the stack edge. Depending on the position of the feeler roller, you can use electrical switching devices a position of the stack edge in one certain tolerance range can be detected. This is the target position of the stack edge defined recognized and can by means of the actuators on the stacking plate be followed up. The sensor arrangement shown acts as a result of it Arrangement is not linear. The scanning of curve segments affects the Tolerances unfavorable.

Ziel der Erfindung ist es, die Sensoreinrichtung zu vereinfachen.The aim of the invention is to simplify the sensor device.

In Figur 1 ist eine Einrichtung dargestellt, die sowohl der Seitenausrichtung eines Bogenstapels 1 als auch der Belüftung zu vereinzelnder Bogen dient. Dazu ist im vorderen Bereich in Bogentransportrichtung gegenüber einer Seitenkante des Bogenstapels 1 ein Bläser 2 zugeordnet. Faktisch sind beiderseits des Bogenstapels 1 Bläser 2 angeordnet. Der Bläser 2 ist an einer Halterung 3 befestigt. Die Halterung 3 wiederum ist auf einer Achse 4 einstellbar festklemmbar. An der gleichen Halterung 3 ist ein Hebel 7 befestigt, der eine Tastrolle 6 trägt. Die gesamte Anordnung ist mittels eines Klemmhebels 10 in einer bestimmten, z.B. formatabhängigen, Position arretierbar.In Figure 1, a device is shown, both the side orientation of a Sheet stack 1 and the ventilation to be separated sheet is used. This is in front area in the sheet transport direction opposite a side edge of the Sheet stack 1 assigned a blower 2. In fact, both sides of the Sheet stack 1 wind 2 arranged. The blower 2 is on a holder 3 attached. The holder 3 is in turn adjustable clampable on an axis 4. On the same bracket 3, a lever 7 is attached, which carries a feeler roller 6. The entire arrangement is by means of a clamping lever 10 in a certain, e.g. format-dependent, position lockable.

Dazu ist in Figur 2 die Anordnung aus einer anderen Ansicht dargestellt. Hierbei ist wiederum der Bläser 2 nunmehr mit sichtbaren Blasöffnungen dargestellt. In der Halterung 3 ist wiederum eine Öffnung 5 gezeigt, die eine hier nicht dargestellte Welle aufnimmt. Auf dieser Welle kann die Halterung 3 in Längsrichtung der Welle bzw. quer zur Transportrichtung der Bogen verschoben werden, so daß der Abstand des Bläsers 2 bzw. der Tastrolle 6 zur Seitenkante des Bogenstapels 1 veränderbar wird. Dazu ist die Klemmeinrichtung aus Figur 1 geeignet. Weiterhin ist in Figur 2 die Schwenkachse 4 dargestellt, mittels derer der Bläser 2 bzw. die Tastrolle 6 in ihrer vertikalen Lage bezüglich der Bogenseitenkante des Bogenstapels 1 veränderbar ist. Weiterhin ist dargestellt, wie der Hebel 7 mit der Tastrolle 6 an dem Halterung 3 befestigt ist. Dazu ist eine schwenkbare Verbindung in Form eines Gelenkes vorgesehen.For this purpose, the arrangement is shown in another view in FIG. Here is again the blower 2 is now shown with visible blowing openings. In the Bracket 3 is again shown an opening 5, which is not shown here Wave picks up. On this shaft, the holder 3 in the longitudinal direction of the shaft or be moved transversely to the transport direction of the sheet, so that the Distance of the blower 2 or the feeler roller 6 from the side edge of the sheet stack 1 is changeable. The clamping device from FIG. 1 is suitable for this. Farther is shown in Figure 2, the pivot axis 4, by means of which the blower 2 and the Tracer roller 6 in its vertical position with respect to the sheet side edge of the Sheet stack 1 is changeable. It is also shown how the lever 7 with the Tracer roller 6 is attached to the bracket 3. There is a swivel Connection provided in the form of a joint.

Die detailliertere Darstellung in Figur 3 zeigt die Funktionsweise der Sensoranordnung auf. Der Hebel 7, der die Tastrolle 6 trägt, ist mittels eines Gelenkes 11 auf einem weiteren Halter 8 schwenkbar befestigt. Zur Ausrichtung des Hebels 7 zum Halter 8 ist eine Biegefeder 14 vorgesehen. Die Biegefeder 14 ist im Halter 8 geklemmt. Weiterhin ist die Biegefeder 14 in einem Gelenkelement 15 gefasst. Das Gelenkelement 15 sitzt an dem Hebel 7 und weist eine Öffnung auf, die die Biegefeder 14 ungespannt aufnimmt. Innerhalb des Gelenkelementes 15 kann sich die Biegefeder 14 sowohl in Längsrichtung bewegen als auch eine Kippbewegung zum Hebel 7 ausführen.The more detailed illustration in FIG. 3 shows how the Sensor arrangement on. The lever 7, which carries the feeler roller 6, is by means of a Joint 11 pivotally attached to a further holder 8. For alignment of the lever 7 to the holder 8, a spiral spring 14 is provided. The spiral spring 14 is clamped in the holder 8. Furthermore, the spiral spring 14 is in a joint element 15 composed. The joint element 15 sits on the lever 7 and has an opening on, which receives the spiral spring 14 untensioned. Within the joint element 15, the spiral spring 14 can move in the longitudinal direction as well as one Carry out a tilting movement to lever 7.

Die Anordnung ist in Figur 4 aus einer zweiten Ansicht dargestellt. Hierbei ist insbesondere auch das Gelenkelement 15 mit seinen Bewegungsmöglichkeiten auf dem Hebel 7 erkennbar.The arrangement is shown in Figure 4 from a second view. Here is especially the joint element 15 with its possibilities of movement the lever 7 recognizable.

Die Funktionsweise der Sensoranordnung ist wie folgt:The sensor arrangement works as follows:

Bei Anlenkung der Tastrolle 6 gegen eine Seitenkante eines Bogenstapels 1 kann sich der Hebel 7 infolge der Wirkung der Biegefeder 14 um ein bestimmtes Maß aus seiner gesteckten Lage in Bezug auf den Halter 8 bewegen. Hierbei wird das obere Ende des Hebels 7 in bezug auf einen Präzisionsschalter 9 verändert. Der Präzisionsschalter 9 ist in Figur 3 und Figur 4 als auf dem Halter 8 befestigt dargestellt. Der Präzisionsschalter 9 wirkt in einer nicht näher zu bezeichnenden Weise auf ein Markierungsobjekt, wie z. B. eine Seitenkante des Hebels 7. Durch Verlagerung des Hebels 7 bzw. von dessen oberem Ende ergibt sich eine Änderung der Relativlage der entsprechenden Markierungskante oder des Markierungsobjektes zum Präzisionsschalter 9, die dieser erfaßt. Der Präzisionsschalter 9 kann hierbei auf eine beliebig kleine oder auch große Toleranzbreite eingestellt werden. Der Präzisionsschalter 9 ist ein beidseitig wirkender Schalter. Das bedeutet, daß die Auslenkung der Tastrolle 6 an dem Hebel 7 nach beiden Seiten erfaßt werden kann. Damit kann die Tastrolle 6 der veränderbaren Stapelseitenkante S folgen. Gleichzeitig wird über die Abtastung des Hebels 7 mittels des Präzisionsschalters 9 bei Überschreiten der Grenzen der Toleranzbreite D ein entsprechendes Signal zur Erzeugung einer der abgetasteten Abweichung entgegengerichteten Stellbewegung am Bogenstapel 1 quer zur Bogentransportrichtung ausgegeben.When articulating the feeler roller 6 against a side edge of a sheet stack 1 can the lever 7 due to the action of the spiral spring 14 by a certain amount move from its inserted position in relation to the holder 8. Here is the changed the upper end of the lever 7 with respect to a precision switch 9. The Precision switch 9 is attached in Figure 3 and Figure 4 as on the holder 8 shown. The precision switch 9 acts in an unspecified Way to a marking object, such as. B. a side edge of the lever 7. By Shifting the lever 7 or from its upper end results in a Change the relative position of the corresponding marking edge or the Marking object to the precision switch 9, which this detects. The Precision switch 9 can be any small or large Tolerance range can be set. The precision switch 9 is on both sides acting switch. This means that the deflection of the feeler roller 6 on the Lever 7 can be detected on both sides. So that the tracer roller 6 changeable stack side edge S follow. At the same time, the scanning of the lever 7 by means of the precision switch 9 when the limits of Tolerance width D a corresponding signal to generate one of the scanned Deviation of opposite movement on the sheet stack 1 across Sheet transport direction output.

Gegen die anstellende Wirkung der Biegefeder 14 ist aber durch die Anlenkung nur einer einzigen Bogenstapelkante auch nur eine Bewegung in einer Richtung ausführbar. Daher können im Normalfall zwei Tastrollen 6, d.h. für jede Stapelseitenkante S eine Tastrolle 6 vorgesehen werden. Against the hiring effect of the spiral spring 14 is due to the articulation only a single sheet stack edge even a movement in one direction executable. Therefore, two tracer rollers 6, i.e. for every Stack side edge S a sensing roller 6 can be provided.

Soll dagegen nur eine Tastrolle 6 verwendet werden, muß der Präzisionsschalter 9 mit seiner Einstellung der Toleranzgrenzen im Bereich der gegen die Biegefeder 14 wirkenden Auslenkung von Hebel 7 und Tastrolle 6 eingestellt sein. Die Nullage bei entspannter Feder kann dabei die eine Toleranzgrenze definieren, so daß die Tastrolle 6 im Ruhezustand an der Toleranzgrenze zur maximalen Abweichung in Richtung des Bogenstapels 1 zu liegen kommt. Der Hebel 7 mit der Tastrolle 6 steht demgemäß in seiner Nullage gegenüber der Halterung 3 in Richtung zur Stapelseitenkante hin schief. Von der Nullage aus erstreckt sich dann die Toleranzbreite der Stapelseitenkante S nach außen vom Bogenstapel 1 weg.If, on the other hand, only one tracer roller 6 is to be used, the precision switch 9 with its setting of the tolerance limits in the area against the spiral spring 14 acting deflection of lever 7 and roller 6 can be set. The zero position with the spring relaxed, it can define a tolerance limit so that the Tracer roller 6 in the idle state at the tolerance limit for the maximum deviation in Direction of the sheet stack 1 comes to lie. The lever 7 with the feeler roller 6 is accordingly in its zero position with respect to the holder 3 in the direction of Stack side edge skewed. The then extends from the zero position Tolerance width of the stack side edge S to the outside of the sheet stack 1 away.

Durch die hier beschriebene Anordnung wird ein größerer Regelbereich bei der Abtastung von Stapelseitenkanten S gegenüber der weiter oben beschriebenen Anordnung erreicht, so daß man mit nur einer einzigen Abtasteinrichtung auskommen kann.Due to the arrangement described here, a larger control range in the Scanning of stack side edges S compared to that described above Arranged so that you can with only a single scanner can get by.

Diese prinzipielle Wirkungsweise wiederum gilt für beide Stapelseitenkante S in entgegengesetzter Richtung gleich. Damit zeigt sich auf ganz einfache Weise, daß die gleiche Sensoranordnung in gleicher Art und Weise mit den beschriebenen Vorteilen für beide Stapelseitenkanten S, d.h. hier allerdings in jeweils entgegengesetzter Richtungen wirkend, einsetzbar ist.This principle of operation in turn applies to both sides of the stack S in opposite direction the same. This shows in a very simple way that the same sensor arrangement in the same way with those described Advantages for both sides of the stack S, i.e. here, however, in each acting in opposite directions, can be used.

Die gesamte Anordnung ist mittels der Klemmeinrichtung 10 auf beliebige Positionen bei beliebigen Bogenformaten zu einem Bogenstapel 1 einstellbar. Hierbei ist ein Mitnehmer 12 vorgesehen, der beispielsweise mit der Halterung 3 des Bläsers 2 verbunden werden kann, so daß die Einstellung der Tastrolle 6 zur Bogenstapelseitenkante S gleichzeitig mit der Einstellung des Bläsers 2 erfolgt. Weiterhin ist es möglich, in der Öffnung 5 der Halterung 3 ein Gewinde vorzusehen. Damit kann die gesamte Anordnung auf einer Gewindespindel angeordnet und femgesteuert automatisch einstellbar bzw. verfahrbar gemacht werden.The entire arrangement is arbitrary by means of the clamping device 10 Positions for any sheet formats for a sheet stack 1 can be set. In this case, a driver 12 is provided which, for example, with the holder 3 of the blower 2 can be connected so that the setting of the feeler roller 6 Sheet stack side edge S takes place simultaneously with the setting of the fan 2. Furthermore, it is possible to have a thread in the opening 5 of the holder 3 provided. So that the entire arrangement on a threaded spindle arranged and automatically controlled or made movable by remote control become.

Der wesentliche Vorteil der Einrichtung in Form ihrer einfachen Bauweise und flexiblen Einsetzbarkeit ist nicht auf die hier speziell dargestellte Bauform beschränkt.The main advantage of the facility in the form of its simple construction and flexible use is not based on the design shown here limited.
