Abstract
Description
Die Erfindung betrifft eine Stapelvorrichtung für flache, auf ihren Schmalseiten stehende Sendungen, mit Führungsmitteln zum Leiten der zugeführten Sendungen in eine Einstapelstelle auf eine Stapelunterlage gegen eine Stützwand, an der die Sendungen abgebremst werden und an der entlang die Sendungen einen Stapel bilden, einer in Stapelrichtung an einer Linearführung verschiebbaren Stapelplatte zum Abstützen des Stapels an seiner stromabwärtigen Stirnseite und einer an der Stapelplatte angreifenden, auf eine Spule aufgewickelten Rollfeder zur Erzeugung einer zum sich aufbauenden Stapel hin gerichteten Andruckkraft der Stapelplatte.The The invention relates to a stacking device for flat, on their narrow sides standing shipments, with guidance for routing the consignments in a stacking point on a stack support against a support wall, at which the shipments are slowed down and along the shipments form a stack, a displaceable in the stacking direction on a linear guide Stacking plate for supporting the stack at its downstream end face and an attacking on the stacking plate, wound on a spool Roll spring for generating a stack to be directed towards Pressure force of the stacking plate.

Erfindung liegt die Aufgabe zugrunde, die aus der
Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass die Rollfeder in einem Anfangsbereich eine degressive und ansonsten horizontale Federkennlinie aufweist. Die Vereinfachung der vorgeschlagenen Lösung besteht somit darin, die Rollfeder selbst als Dämpfungselement zu verwenden, indem eine über die Länge der Rollfeder unterschiedliche Federkennung gezielt eingesetzt wird. Dadurch kann die Rollfeder zu Beginn ihres Federweges eine stärkere Dämpfung aufweisen, nämlich dann und dort, wo zu Beginn der Stapelbildung ein Zurückprallen der Sendung verhindert werden soll. Sobald sich ein größerer Stapel gebildet hat und der Stapel selbst die Dämpfungsfunktion übernommen hat, kann die Dämpfung der Rollfeder auf das zur geordneten Stapelbildung erforderliche Maß zurückgenommen werden.to solution the object is proposed according to the invention that the scroll spring in a starting area is a degressive and otherwise horizontal spring characteristic has. The simplification of the proposed solution is thus to use the scroll spring itself as a damping element, by having an over the length the spring different springs is used targeted. Thereby the roll spring can have a stronger damping at the beginning of its spring travel, namely then and where at the beginning of the stack formation prevents rebounding of the shipment shall be. As soon as a bigger stack has formed and the stack itself has taken over the damping function, can the damping the scroll spring on the required for ordered stacking Measurement withdrawn become.
Die unterschiedliche Federkennlinie lässt sich durch verschiedene Maßnahmen erreichen. So wird in einer Ausgestaltung der Erfindung vorgeschlagen, die Rollfeder bandförmig mit gleichmäßiger Dicke so auszubilden, dass sie im Anfangsbereich eine größere Breite als im weiteren Bereich aufweist.The different spring characteristic can be different activities to reach. Thus, in one embodiment of the invention, it is proposed the scroll spring band-shaped with uniform thickness so that they form a larger width in the initial area as in the broader area.
In einer anderen Ausgestaltung wird erfindungsgemäß vorgeschlagen, dass die Rollfeder bandförmig mit gleichmäßiger Breite ausgebildet ist und im Anfangsbereich eine größere Dicke als im weiteren Bereich aufweist.In another embodiment, the invention proposes that the scroll spring band-shaped uniform width is formed and in the initial area a greater thickness than in the other Has area.
Es ist aber auch denkbar, beide Gestaltungsmerkmale der Rollfeder zu kombinieren und die Rollfeder bandförmig so auszubilden, dass sie im Anfangsbereich eine größere Breite und Dicke als im weiteren Bereich aufweist.It but is also conceivable, both design features of the scroll spring combine and form the scroll spring band-shaped so that they in the beginning a larger width and thickness than in the broader range.
Schließlich kann erfindungsgemäß die Rollfeder so ausgebildet sein, dass sie im Anfangsbereich einen kleineren Wickelradius aufweist.Finally, can according to the invention the scroll spring be designed so that they have a smaller in the initial area Has winding radius.
Allen Ausführungen ist gemeinsam, dass die Rollfeder selbst zur Dämpfung der am Anfang problematischen Aufprallenergie verwendet wird, indem zu Beginn des Stapelvorganges durch die Gestaltung der Rollfeder eine größere Federwirkung und damit Dämpfung herbeigeführt wird, als nach der Bildung eines Anfangsstapels. Diese Wirkung ist mit sehr einfachen und preiswerten Mitteln erzielbar, ohne dass auf die Vorteile des bekannten aufwändigen Dämpfungselementes verzichtet werden muss.all versions is common that the scroll spring itself to dampen the problematic at the beginning Impact energy is used by at the beginning of the stacking process by the design of the scroll spring a greater spring action and thus damping is brought about, than after the formation of a beginning stack. This effect is with very simple and inexpensive means achievable without on the advantages of the known elaborate damping element must be waived.
