Eine derartige Mehrfachbogenkontrollvorrichtung ist durch die DE 38 23 201 C2 bekannt.Such a multiple sheet control device is known from DE 38 23 201 C2.

Der Hebel zur Betätigung des Schalters und zur Halterung des Tastelementes ist bei der DE 38 23 202 C2 an einer getakteten Welle angeordnet. Die ständige Hin- und Herbewegung des Hebels führt zu Schwingungen der gesamten Vorrichtung und damit zu ungenauen Messergebnissen.The lever for actuating the switch and for holding the pushbutton element is in the DE 38 23 202 C2 arranged on a clocked shaft. The constant back and forth movement of the lever leads to vibrations of the entire device and thus inaccurate Measurement results.

Eine Kontrollvorrichtung für geschuppten Bogentransport zeigt auch die US 2,637,552. Diese weist nebeneinander über die Breite der zu transportierenden Bogen verteilt angeordnete Tastrollen auf, die einzeln gelagert sind und mittels einer Taktwelle gemeinsam periodisch auf und abbewegbar sind. Jede Tastrolle ist individuell höheneinstellbar und axial verstellbar gelagert.A control device for shingled sheet transport also shows US 2,637,552. This points side by side across the width of the sheets to be transported arranged tracer rollers, which are stored individually and by means of a clock shaft are periodically movable up and down together. Each tracer roll is individual adjustable in height and axially adjustable.

Der Erfindung liegt die Aufgabe zugrunde eine Mehrfachbogenkontrollvorrichtung zu schaffen, die mit höherer Präzision arbeitet.The invention has for its object a multiple sheet control device create that works with higher precision.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Ein wesentlicher Vorteil der Erfindung ist die Anordnung von mehreren, mindestens jedoch zwei Tastelementen nebeneinander auf der Traverse. Durch diese Maßnahme kann der Bogen bzw. Bogenstrom an mehreren Stellen gleichzeitig kontrolliert werden. Insbesondere im Randbereich des Bogens oder des Bogenstromes können umgeknickte Ecken zuverlässig detektiert werden.An essential advantage of the invention is the arrangement of several, at least however two probe elements next to each other on the crossbeam. This measure can the arc or arc flow in several places be checked at the same time. Especially in the edge area of the arch or of the arc current, bent corners can be reliably detected.

Ein weiterer Vorteil der Erfindung ist die Anordnung eines Betätigungselementes für ein vorgesehenes Schaltelement drehfest an der schwenkbaren Traverse der Tastelemente.Another advantage of the invention is the arrangement of a Actuating element for a switching element provided on the swiveling traverse of the probe elements.

Es braucht daher nur ein Schalter vorgesehen zu werden, da jedes Tastelement drehfest auf der schwenkbaren Traverse angeordnet ist, führt jede Auslenkung eines Tastelements zur Betätigung des Schalters.Therefore, only one switch needs to be provided, since each Each sensing element is arranged in a rotationally fixed manner on the swiveling traverse Deflection of a push button to actuate the switch.

Vorzugsweise wird die Mehrfachbogenkontrollvorrichtung am Anfang des Fördertisches eingesetzt. Durch diese Maßnahme ergibt sich ein großes Zeitfenster zum Anhalten der Bogen verarbeitenden Maschine, insbesondere Druckmaschine, auch bei hohen Verarbeitungsgeschwindigkeiten.Preferably, the multiple sheet control device at the beginning of the Conveyor table used. This measure results in a big one Time window for stopping the sheet processing machine, in particular Printing machine, even at high processing speeds.

In vorteilhafter Weise wird der Bogen bzw. geschuppte Bogenstrom berührungsfrei zur Tastrolle kontrolliert, da nur bei Mehrfachbogen oder fehlerhaften Bogen die Tastrolle berührt wird und eine Schwenkbewegung initiiert wird, die ein Stillsetzen der Bogenförderung zur Folge hat.Advantageously, the arc or shingled arc stream Checked without contact to the feeler roller, since only with multiple sheets or defective bow the touch roller is touched and a pivoting movement is initiated, which results in the stopping of sheet feeding.

Eine Rotationsdruckmaschine, z. B. Bogen 7 verarbeitende Druckmaschine 1, weist einen Anleger 2, mindestens ein Druckwerk 3 bzw. 4 und einen Ausleger 6 auf. Die Bogen 7 werden von einem Bogenstapel 8 entnommen und vereinzelt oder schuppenförmig über einen Zuführtisch 9 den Druckwerken 3 und 4 zugeführt. Diese enthalten in bekannter Weise jeweils einen Plattenzylinder 11; 12. Die Plattenzylinder 11 und 12 weisen jeweils eine Vorrichtung 13, 14 zum Befestigen flexibler Druckplatten 16 auf. Darüber hinaus ist jedem Plattenzylinder 11; 12 eine Vorrichtung 15; 17 für den halboder vollautomatischen Druckplattenwechsel zugeordnet.A rotary printing machine, e.g. B. sheet 7 processing printing machine 1, has a feeder 2, at least one printing unit 3 or 4 and one Boom 6 on. The sheets 7 are removed from a sheet stack 8 and isolated or in scaly form via a feed table 9 to the printing units 3 and 4 fed. These each contain one in a known manner Plate cylinder 11; 12. The plate cylinders 11 and 12 each have one Device 13, 14 for attaching flexible pressure plates 16. About that each plate cylinder 11; 12 a device 15; 17 for the half or fully automatic printing plate change assigned.

Zwischen Anleger 2 und Zuführtisch 9 ist zunächst in Bogenförderrichtung gesehen ein Taktrollenpaar 18, 19 angeordnet. Die Taktrolle 18 ist frei drehbar gelagert und wird auf und ab bewegt, wodurch sich ein Abstand der Taktrolle 18 zur angetriebenen Gegenrolle 19 im Takt der Bogen verarbeitenden Maschine verringert und vergrößert. Dem Taktrollenpaar 18, 19 ist in Bogenförderrichtung eine erfindungsgemäße Mehrfachbogenkontrollvorrichtung 21 nachgeordnet, die sich am Anfang des Zuführtisches 9 befindet. Die Mehrfachbogenkontrollvorrichtung 21 besteht im wesentlichen aus einer frei drehbar gelagerten Gegenrolle 22, die in einer Aussparung 23 des Zuführtisches 21 angeordnet ist und einem der Gegenrolle 22 oberhalb des Zuführtisches 21 gegenüber angeordneten Tastelement 24. Between feeder 2 and feed table 9 is initially in the sheet conveying direction seen a pair of clock rollers 18, 19 arranged. The clock roller 18 is freely rotatable stored and is moved up and down, creating a distance of Clock roller 18 to the driven counter roller 19 in time with the bow processing machine reduced and enlarged. The clock roller pair 18, 19 is an inventive in the sheet conveying direction Multiple sheet control device 21 downstream, which at the beginning of Feed table 9 is located. The multiple sheet control device 21 consists in essentially from a freely rotatably mounted counter roller 22, which in a Recess 23 of the feed table 21 is arranged and one of the Counter roller 22 arranged above the feed table 21 opposite Tactile element 24.

Das Tastelement 24 ist vorzugsweise als drehbar gelagerte Rolle ausgebildet. Andere Formen wie Gleitschuh, Bügel, Taststift oder dergleichen sind denkbar.The feeler element 24 is preferably designed as a rotatably mounted roller. Other shapes such as sliding shoe, bracket, stylus or the like are conceivable.

Die drehbar gelagerte Rolle 24 sitzt an einem schwenkbar an einer Halterung 26 gelagerten Hebel 27. Die Halterung 26 ist axial verschiebbar auf einer Traverse 28 angeordnet. Eine Arretierschraube 29 dient zum Festsetzen der Halterung 26 in einer gewünschten Position. An der Halterung 26 ist eine Druckfeder 31 abgestützt, die mit einem Ende auf einen Arm 32 des Hebels 27 einwirkt, so daß dieser gegen einen einstellbaren Anschlag 33 gedrückt wird.The rotatably mounted roller 24 is pivotally seated on a bracket 26 mounted lever 27. The bracket 26 is axially displaceable on a Traverse 28 arranged. A locking screw 29 is used to fix the Bracket 26 in a desired position. On the bracket 26 is one Compression spring 31 supported with one end on an arm 32 of the lever 27 acts so that it is pressed against an adjustable stop 33.

Die Traverse 28 ist in Seitengestellen 34, 36 schwenkbar gelagert. In der Nähe des Seitengestells 34 weist die Traverse 28 einen Hebel 37 auf. !The cross member 28 is pivotally mounted in side frames 34, 36. Nearby of the side frame 34, the cross member 28 has a lever 37. !

Auf einem Lagerzapfen 38 der Traverse 28 sitzt schwenkbar ein Halter 39 für einen Schalter 41 zum Stillsetzen der Bogenförderung.On a bearing pin 38 of the cross member 28, a holder 39 is pivotally seated a switch 41 for stopping the sheet feeding.

Darüber hinaus trägt der Halter 39 einen Anschlag 42, der an dem Hebel 37 anliegt. Eine am Seitengestell 34 abgestützte Druckfeder 44 drückt den Hebel 37 gegen den Anschlag 42. Eine Justierschraube 46 wirkt mit dem Halter 37 zusammen und schwenkt diesen um den Lagerzapfen 38 gegen die Kraft der Druckfeder 44. Durch diese Maßnahme wird bei Änderung der Bedruckstoffstärke der Abstand zwischen Rolle 24 und der Gegenrolle 22 eingestellt.In addition, the holder 39 carries a stop 42 which is connected to the lever 37 is applied. A compression spring 44 supported on the side frame 34 presses the Lever 37 against the stop 42. An adjusting screw 46 acts with the Holder 37 together and swings it around the bearing pin 38 against the Force of the compression spring 44. This measure changes the Substrate thickness the distance between roller 24 and counter roller 22 set.

Auf der Traverse 28 werden zur Erkennung von kleinen Bogenstückchen oder - schnipsel eine größere Anzahl, Halterungen 26 mit jeweils einer zugeordneten Tastrolle 24 angeordnet. Zur gemeinsamen Verstellung sämtlicher auf der Traverse 28 angeordneten Tastrollen 24 auf die zu verarbeitende Bogenstärke, z. B. Bedruckstoffstärke bei Druckmaschinen wird die gemeinsame Justierschraube 46 verwendet.On the traverse 28 are used to detect small pieces of bow or - snip a larger number, brackets 26, each with an associated Taster roller 24 arranged. For the common adjustment of all on the Traverse 28 arranged feeler rollers 24 on the sheet thickness to be processed, z. B. substrate thickness in printing machines is the common Adjustment screw 46 used.

Zur Höhenausrichtung der Tastrollen 24 untereinander ist der verstellbare Anschlag 33 vorgesehen, z. B. bei der Grundeinstellung in der Montage.For the vertical alignment of the feeler rollers 24 with one another, the adjustable one Stop 33 provided, for. B. in the basic setting during assembly.

Die Auslenkung einer einzigen Tastrolle 24 hat zur Folge, daß die Traverse 28 gegen die Kraft der Druckfeder 44 geschwenkt wird, die an dem Hebel 37 anliegt. Bei der Schwenkbewegung gelangt der Hebel 37 in Kontakt mit dem Schalter 41, der daraufhin die Bogenförderung stoppt. The deflection of a single feeler roller 24 has the consequence that the cross member 28 is pivoted against the force of the compression spring 44 on the lever 37 is applied. During the pivoting movement, the lever 37 comes into contact with the Switch 41, which then stops the sheet feed.
