Abstract
Greifersystemkörper zum Transport von Bogen in bogenverarbeitenden Maschinen mit einem Greifersystem zum Fixieren einer Bogenkante, der einen tropfenförmigen Querschnitt und eine Abrisskante (9) aufweist und von umlaufenden Transportmitteln entlang eines Bogenförderweges bewegbar ist, wobei der Greifersystemkörper von Luft umströmt wird, wobei sich dem tropfenförmigen Querschnitt entgegen der Bedruckstoffförderrichtung (BFR) ein sich verjüngender Querschnitt anschließt, wobei der Greifersystemkörper als ein Hohlprofil aufweisender Greiferwagen (1) ausgebildet ist, der eine Greiferwelle (4) umfasst, der Greiferfinger (3) zugeordnet sind, die mit Greiferauflagen (2) zusammenwirken, wobei der Greiferwagen (1) eine maximale Greiferwagenhöhe (8) aufweist und die Abrisskante (9) zwischen 9/10 und 8/10 der maximalen Greiferwagenhöhe (8) angeordnet ist.Gripper system body for transporting sheets in sheet-processing machines with a gripper system for fixing a sheet edge, which has a teardrop-shaped cross section and a spoiler edge (9) and is movable by circulating transport along a Bogenförderweges, wherein the gripper system body is flowed around by air, wherein the teardrop-shaped cross-section opposite to the Bedruckstoffförderrichtung (BFR) followed by a tapered cross-section, wherein the gripper system body is designed as a hollow profile gripper carriage (1) comprising a gripper shaft (4) associated with the gripper fingers (3), which cooperate with gripper pads (2), wherein the gripper carriage (1) has a maximum gripper carriage height (8) and the trailing edge (9) between 9/10 and 8/10 of the maximum gripper carriage height (8) is arranged.
Description
Die Erfindung betrifft einen Greifersystemkörper zum Transport von Bogen in bogenverarbeitenden Maschinen gemäß den Merkmalen des 1. Anspruchs.The invention relates to a gripper system body for transporting sheets in sheet-processing machines according to the features of the first claim.
Als Förderorgan eines Fördersystems im Ausleger einer Bogendruckmaschine kommen an Ketten befestigte und von diesen bewegte Greiferwagen zum Einsatz. Durch die Bewegung dieser Greiferwagen in den Maschinen werden deren Konturen von Luft umströmt. Dabei findet ein Strömungsabriss am Greiferwagen statt. Dieser Strömungsabriss tritt in Wechselwirkung mit den zu fördernden Bogen und führt zum Teil zu erheblichen Bewegungen des Bogens mit daraus resultierenden Problemen der Bogenhandhabung und des Abschmierens.As a conveying member of a conveyor system in the boom of a sheet-fed press come attached to chains and moving from these gripper carriage used. Due to the movement of these gripper carriages in the machines, air flows around their contours. In this case, a stall takes place on the gripper carriage. This stall occurs in interaction with the sheets to be conveyed and in part leads to significant bow movements with consequent sheet handling and smearing problems.
Bisherige Greiferwagen wurden vorzugsweise nach Festigkeitskriterien entwickelt, wobei mit steigenden Fördergeschwindigkeiten deren strömungstechnische Nachteile deutlich hervortreten. Zum Beispiel wurden zylindrische Konstruktionen gewählt, die bekannter Maßen zur Ausbildung der Karmanschen Wirbelstraße führen. Diese Strömungen führen zu erheblichen Problemen bei dem Fördervorgang des Bogens und werden als ungünstig angesehen.Previous gripper carriages have preferably been developed according to strength criteria, with their fluidic disadvantages clearly emerging with increasing conveying speeds. For example, cylindrical structures have been chosen which, as is known, lead to the formation of the Karman vortex street. These flows lead to significant problems in the conveying process of the bow and are considered unfavorable.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Greifersystemkörper zu schaffen, der eine verbesserte Luftführung aufweist und einen sicheren Puderauftrag ermöglicht.The invention is therefore an object of the invention to provide a gripper system body, which has an improved air flow and allows a safe powder application.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des 1. Anspruchs gelöst.According to the invention the object is achieved by a device having the features of the first claim.
Die Erfindung hat den Vorteil, dass eine verbesserte Luftführung erreicht wird. Der strömungstechnisch relevante Querschnitt des Greiferwagens wird derart gemindert, dass der negative Effekt der Evakuierung hinter dem Greiferwagen minimiert wird und der Raum hinter dem Greiferwagen durch gezielte Luftführung mit Luft befüllt wird. Gleichzeitig wird durch die gerichtete Luftführung ein sicherer Puderauftrag ermöglicht.The invention has the advantage that an improved air flow is achieved. The fluidically relevant cross section of the gripper carriage is reduced in such a way that the negative effect of the evacuation behind the gripper carriage is minimized and the space behind the gripper carriage is filled with air by targeted air guidance. At the same time a reliable powder application is made possible by the directional air flow.
Im Folgenden soll die Erfindung beispielhaft erläutert werden. Die dazugehörige Zeichnung stellt dabei schematisch dar:
-
1 : Greiferwagen mit tropfenförmigem Querschnitt und sich anschließendem verjüngenden Querschnitt, der eine Abrisskante aufweist.
-
1 : Gripper carriage with drop-shaped cross-section and subsequent tapering cross-section, which has a spoiler lip.

Zur Wirkungsweise der erfindungsgemäßen Einrichtung: Das Greiferwagenprofil wird auf der dem Bogenleitblech abgewandten Seite so gestaltet, dass die verdrängte Luft beim Umströmen der Greiferwagenkontur nicht von dieser abgelenkt, sondern gezielt in den Rezirkulationsraum einströmt.For the operation of the device according to the invention: The gripper carriage profile is designed on the side facing away from the sheet guide plate so that the displaced air is not deflected by the gripper carriage contour of this, but selectively flows into the recirculation space.
Zu diesem Zweck wird eine stetige Greiferwagenkontur ohne Kanten gestaltet, um ungewollte Strömungsabrisse zu verhindern. Am strömungstechnischen Ende des Profils wird eine gezielte scharfe Abrisskante
