Abstract

The gripper (4) which is fastened on a link chain consists of a rigid advancing part (5) which is provided with bearing surface (7) and stopping surface (8), and a spring element (9) attached on a following chain link and which acts with spring pressure on the bearing surface (7) with its free arm (10) in the extended chain position. By deflecting the link chain, the grippers (4) are automatically opened and closed again. <IMAGE>

Description

Die Erfindung bezieht sich auf einen selbsttätigen, auf handelsüblichen Befestigungselementen von Gliederketten befestigten Greifer für Kettenausleger von Druckmaschinen.The invention relates to an automatic gripper fastened to commercially available fasteners of link chains for chain arms of printing machines.

Greifer von Kettenauslegern ermöglichen den zwangsweisen Weitertransport von aus Druckmaschinen anfallenden Druckprodukten, indem sie an der Uebernahmestelle das Druckprodukt erfassen und an der Uebergabestelle wieder freigeben.Grippers of chain arms enable the forced transport of printed products from printing machines by capturing the printed product at the pick-up point and releasing it again at the transfer point.

Greifer für Kettenausleger sind in verschiedenen Ausführungen bekannt. Vor der Uebernahme der Druckprodukte werden sie durch eine Steuerung irgendwelcher Art geöffnet und zum Erfassen der Druckprodukte meist mittels Federdruck geschlossen. An der Uebergabestelle sorgt wieder eine Steuerung für das Oeffnen der Greifer.Grippers for chain brackets are known in various designs. Before the printed products are taken over, they are opened by a control of any kind and are usually closed by spring pressure to capture the printed products. At the transfer point, a control system again opens the grippers.

Alle derartigen Greifer, wie sie z.B. aus der schwedischen Patentschrift 7704188-7 bekannt sind, bedingen mindestens einen beweglichen Greiferteil und damit dem Verschleiss unterworfene Lagerstellen, sowie den Ausleger verteuernde Steuerkurven oder Betätigungselemente od. dgl.All such grippers, e.g. are known from the Swedish patent specification 7704188-7, require at least one movable gripper part and thus bearings subject to wear, and control cams or actuating elements or the like which make the boom more expensive.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie im Anspruch gekennzeichnet ist, löst die Aufgabe, einen selbsttätigen Greifer für Kettenausleger von Druckmaschinen zu schaffen, bei dem die Greifer an den Kettenumlenkpunkten automatisch geöffnet und wieder geschlossen werden.The invention seeks to remedy this. The invention, as characterized in the claim, solves the problem of creating an automatic gripper for chain arms of printing presses, in which the grippers are automatically opened and closed again at the chain deflection points.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass der Greifer frei von beweglichen Teilen und damit frei von dem Verschleiss unterworfenen Lagerstellen ist und keine spezielle Steuerung benötigt. Insgesamt zeichnet sich der Greifer durch seinen äusserst einfachen Aufbau und eine hohe Lebensdauer aus.The advantages achieved by the invention are essential Lichen can be seen in the fact that the gripper is free of moving parts and thus free of the bearings subject to wear and does not require any special control. Overall, the gripper is characterized by its extremely simple structure and long service life.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt

  • Figur 1 einen mit erfindungsgemässen Greifern bestückten Kettenausleger,
  • Figur 2 einen Greifer in geöffnetem Zustand und
  • Figur 3 einen Greifer in geschlossenem Zustand.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. It shows
  • 1 shows a chain boom equipped with grippers according to the invention,
  • Figure 2 shows a gripper in the open state and
  • Figure 3 shows a gripper in the closed state.

In den Figuren ist ein Kettenausleger mit selbsttätigen Greifern dargestellt. Im Kettenausleger 1 sind mit der, mit handelsüblichen Befestigungselementen 2 versehenen Gliederkette 3 Greifer 4 entsprechend der gewünschten Auslegedistanz der Druckprodukte 5 fest verbunden. Der vorlaufende Teil 6 des Greifers 4 ist mit einer Auflagefläche 7, die durch eine Anschlagfläche 8 begrenzt ist, versehen. Mit den Befestigungselementen 2' eines nachfolgenden Kettengliedes ist der nachlaufende Teil des Greifers 4, ein Federelement 9, beispielsweise eine Blattfeder, fest verbunden, dessen freier Schenkel 10 bei gestreckter Kettenlage mit Federdruck auf die Auflagefläche 7 einwirkt. Durch Umlenken der Gliederkette 3 öffnet sich der Greifer 4 automatisch entsprechend dem Durchmesser des Kettenumlenkrades 11, 11' um sich beim Uebergang in die gestreckte Kettenlage wieder zu schliessen. Der Kettenausleger 1 ist in bekannter Art und Weise so gelagert, dass er, resp. die Greifer 4 an der Uebernahmestelle zur Uebernahme der Druckprodukte 5 einstellbar ist.A chain boom with automatic grippers is shown in the figures. In the chain arm 1, the link chain 3, provided with commercially available fastening elements 2, 3 grippers 4 are firmly connected in accordance with the desired delivery distance of the printed products 5. The leading part 6 of the gripper 4 is provided with a support surface 7 which is delimited by a stop surface 8. The trailing part of the gripper 4, a spring element 9, for example a leaf spring, is firmly connected to the fastening elements 2 'of a subsequent chain link, the free leg 10 of which acts on the bearing surface 7 with spring pressure when the chain position is extended. By deflecting the link chain 3, the gripper 4 opens automatically in accordance with the diameter of the chain deflection wheel 11, 11 'in order to close again when it transitions into the stretched chain position. The chain boom 1 is mounted in a known manner so that it, respectively. the gripper 4 at the takeover point for taking over the printed products 5 is adjustable.
