Description
Die Erfindung betrifft einen Sauger zum Trennen und Transportieren bogenförmigen Materials, insbesondere in Bogendruckmaschinen.The The invention relates to a suction device for separating and transporting sheet material, especially in sheetfed presses.
Zum
Trennen des jeweils obersten Bogens eines Bogenstapels und nachfolgenden
Transportieren zu einer bogenverarbeitenden Maschine sind Sauger
bekannt. Diese Sauger werden durch ein Kraftpotential in Richtung
des Bogenstapels bewegt und erfassen nach dem Aufsetzen auf den
Bogenstapel mittels Unterdruck den zu trennenden Bogen. Durch gesteuerte
Saugmittel werden die Sauger entgegen dem in Richtung des Bogenstapels
wirkenden Kraftpotentials bewegt und damit der zu vereinzelnde Bogen
aus einer Bogentrenn- in eine Bogentransportposition gefördert (
Diese Sauger haben den gemeinsamen Nachteil, daß sie unter der Wirkung des Kraftpotentials in der Bogentrennposition verharren, wenn kein Bogen erfaßt wird.These Suckers have the common disadvantage that they are under the effect of Force potential remain in the sheet separation position, if no bow detected becomes.
Das bedeutet, daß mit diesen Saugern, um Beschädigungen zu vermeiden, lediglich eine etwa senkrecht zur Bogenstapelebene verlaufende Hubbewegung (Trennsauger) oder eine von der Senkrechten abweichende Transportbewegung realisiert werden kann, wenn si chergestellt ist, daß im Fall des Nichterfassens eines Bogens eine Kollision der Sauger mit weiteren Bauteilen ausgeschlossen werden kann.The means that with these suckers to damage to avoid only one approximately perpendicular to the sheet pile plane running stroke movement (separating suction) or one of the vertical Deviating transport movement can be realized if si chergestellt is that in the Case of not catching a bow a collision of the suckers with other components can be excluded.
Außerdem weisen die Sauger den Nachteil auf, daß diese, wenn sie im Abstand nebeneinander über eine Formatbreite verteilt angeordnet sind, zu unterschiedlichen Zeitpunkten den Rückhub beginnen. Das bedeutet, daß flexible und instabile Bogen wellenförmig verformt werden, so daß das Einsatzgebiet der Sauger weiter eingeschränkt wird.In addition, show the suckers have the disadvantage that these, if they are distributed at a distance next to each other over a format width are arranged to start the return stroke at different times. That means flexible and unstable arcs wavy be deformed so that the Field of application of the sucker is further restricted.
Aufgabe der Erfindung ist die Schaffung eines universell einsetzbaren Saugers zum Trennen und Transportieren bogenförmigen Materials.task The invention is the creation of a universally applicable sucker for separating and transporting sheet material.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des ersten Anspruchs gelöst.According to the invention Problem solved by the features of the first claim.
Durch die erfindungsgemäße Lösung wird gesichert, daß der Sauger auch dann aus der Bogentrennposition zurückgeführt wird, wenn kein Bogen erfaßt wurde. Damit ist es möglich, mit diesen Saugern Transportbewegungen zu realisieren, die nicht lediglich durch eine Hubbewegung erfüllt werden können, ohne zusätzliche Mittel vorsehen zu müssen, die in jedem Fall sicher eine Kollision der Sauger mit anderen Bauelementen ausschließen.By the solution according to the invention is secured, that the Sucker is then returned from the sheet separation position, if no sheet was detected. This makes it possible to realize with these suckers transport movements, not only fulfilled by a lifting movement can be without additional To provide funds In any case, the collision of the suckers with other components is safe exclude.
Außerdem können alle Sauger, wenn diese z.B. über die Formatbreite eines zur Verarbeitung gelangenden bogenförmigen Materials verteilt angeordnet sind, gleichzeitig angesteuert werden, so daß diese in ihrer Gesamtheit zwangsweise aus einer Trennposition in eine Transportposition geführt werden, wodurch Wellenbildungen und Verwerfungen des bogenförmigen Materials ausgeschlossen sind.In addition, everyone can Sucker, if this e.g. above the format width of a sheet material to be processed are distributed, are controlled at the same time, so that this in its entirety forcibly from a separating position into a Transport position led which causes waviness and distortion of the sheet material excluded are.
