Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum sequentiellen Befördern von Bogen in einer Platinenpresse, die Greiferstangen umfasst, deren jeweilige Enden mit zwei biegsamen Elementen in Form von Endlosschleifen verbunden sind, wobei jedes jeweils mit einem Rad zum intermittierenden Antrieb und zumindest einem freien Rad in Eingriff steht, ein viereckiges Arbeitsgestell und einen beweglichen Rahmen, die auf beiden Seiten der Bahn der Greifer der Stange angeordnet sind, und Düsen, die mit einer Zufuhr für Druckluft verbunden sind, um während der Anhaltephase der Greiferstange Luftstrahle in Richtung des beweglichen Rahmens zu leiten, um die Bogen zwischen dem Arbeitsgestell und dem beweglichen Rahmen sukzessive anzuhalten.The The present invention relates to an apparatus for sequential carry of sheets in a platinum press comprising gripper bars whose respective ends with two flexible elements in the form of endless loops each with a wheel for intermittent Drive and at least one free wheel is engaged, a quadrangular Work frame and a movable frame, on both sides the path of the grippers of the rod are arranged, and nozzles that with a feeder for Compressed air are connected to during the stopping phase of the grab bar air jets in the direction of the moving Frame to guide the bows between the work frame and to suspend the movable frame successively.
Wenn eine Greiferstange einen Bogen befördert, erfasst sie diesen an seinem vorderen Rand und leitet ihn zwischen das Arbeitsgestell und die Stanzplatte, die auf dem beweglichen Rahmen der Platinenpresse montiert ist. Am Laufende verlangsamt sich die Greiferstange stark, bevor sie anhält, und wird angehoben, sobald sie am hinteren Querrand des Arbeitsgestells austritt.If a rapier bar conveys a bow, it records this its front edge and guides it between the work frame and the punching plate, which is on the moving frame of the blank press is mounted. The gripper bar slows down constantly, before she stops, and is raised as soon as it reaches the rear transverse edge of the work frame exit.
Während dieses brüsken Verfangsamens der Greiferstange ist es wichtig, ein Verformen des Bogens zu verhindern und ihn dazu zu bringen, praktisch eben zu bleiben. Wenn ein auf diese Weise beförderter, biegsamer Bogen einer Verlangsamungskraft ausgesetzt wird, verformt er sich aufgrund der auf ihn ausgeübten Schwerkraft vorrangig nach unten. Aus diesem Grund befinden sich die Greiferstangen vorzugsweise im Bereich der unteren Fläche des Profils, welches die Greiferstange bildet, damit sich der Bogen so nahe wie möglich bei dem beweglichen Rahmen verlagert. Um zu verhindern, dass sich der auf diese Weise verlangsamte Bogen nicht nach oben verformt, ist bereits ein Druckluftstrom zwischen dem Bogen und dem in Inneren des Arbeitsgestells der Platinenpresse befestigten Brett vorgeschlagen worden. Bei den bis jetzt vorgeschlagenen Lösungen sind die Düsen zum Ausblasen von Druckluft jedoch derart hinter dem hinteren Querrand des Arbeitsgestells angeordnet, dass der Druckluftstrom vor dem vollständigen Anhalten der Greifer unterbrochen wird und dass dadurch der Rahmen durch einen doch relativ großen Zwischenraum weiterhin vom Arbeitsgestell getrennt wird. Aus diesem Grund hört das Ausblasen von Luft vor dem Bogen auf, und schließt der in diesem Moment zwischen dem Arbeitsgestell und dem beweglichen Rahmen vorhandene Zwischenraum es nicht aus, dass sich der Bogen unter der Einwirkung des starken Verlangsamens doch verformt.During this brusque Trapping the rapier rod, it is important to a deformation of the bow to prevent and make him stay practically flat. If one transported in this way, flexible bow is subjected to a slowing force, deformed he prioritized due to the gravity applied to him downward. For this reason, the gripper bars are preferably in the area of the lower surface of the profile forming the rapier bar so that the bow as close as possible shifted at the moving frame. To prevent yourself the arc slowed in this way is not deformed upwards, is already a compressed air flow between the bow and the inside proposed the board of the board press mounted board Service. In the solutions proposed so far, the nozzles for Blowing compressed air, however, so behind the rear transverse edge arranged the working frame that the compressed air stream before the complete Stopping the gripper is broken and that thereby the frame through a relatively large one Space is still separated from the work frame. For this Reason hears that Blowing air out in front of the bow, and closing in at that moment the work frame and the movable frame existing gap it is not enough that the arch under the influence of strong Slowing down yet deformed.
Es ist Aufgabe der vorliegenden Erfindung, die oben erwähnten Nachteile, die das Drosseln des Arbeitstakts erzwingen, um das Zerknittern der Bogen zu verhindern, zumindest teilweise zu beheben.It It is an object of the present invention to overcome the above-mentioned disadvantages, that force throttling the work cycle to crumple to prevent the bow, at least partially fix it.
Zu diesem Zweck hat die vorliegende Erfindung eine Vorrichtung zum sequentiellen Befördern von Bogen in einer Platinenpresse gemäß Anspruch 1 zum Zweck.To For this purpose, the present invention has a device for sequential transport of Sheet in a sinker press according to claim 1 for the purpose.
Die Position der Düsen ermöglicht es, den Luftstrom praktisch bis zum Anhalten des Bogens wirkungsvoll zu machen. Aus diesem Grund bleibt der Bogen praktisch eben und wird daher mit höherer Sicherheit angehalten. Dies kann das Erhöhen des Arbeitstakts der Platinenpresse ermöglichen, ohne dass sich die Gefahr von Mängeln oder des Verstopfens der Maschine erhöht. Wie man im Laufe der folgenden Beschreibung feststellen wird, ist die vorgeschlagene Lösung sowohl hinsichtlich der Herstellung als auch der Verwendung der Vorrichtung besonders einfach.The Position of the nozzles allows it effectively, the air flow effectively up to the stop of the bow close. For this reason, the bow remains practically flat and is therefore more secure stopped. This can be increasing allow the working cycle of the blank press, without the Danger of defects or clogging the machine increases. How to go through the following Description, the proposed solution is both as regards the manufacture as well as the use of the device especially easy.
Weitere Merkmale und Vorteile der vorliegenden Erfindung werden im Laufe der nachfolgenden Beschreibung ersichtlich, die mit Hilfe der beigefügten Zeichnungen erstellt wird, welche schematisch und beispielhaft eine Ausführungsform der Beförderungsvorrichtung gemäß der vorliegenden Erfindung erläutern.Further Features and advantages of the present invention will become apparent the following description, with reference to the accompanying drawings which schematically and exemplifies an embodiment the conveyor according to the present Explain the invention.
