Abstract
Description
Vorrichtung zum Transport von Bögen, vorzugsweise Bedruckstoffbögen, insbesondere für eine Druckmaschine, umfassend wenigstens eine Transportrolle, vorzugsweise ein Transportrollenpaar auf einer gemeinsamen Achse, die bevorzugt unangetrieben, frei drehbar gelagert ist und mit einer ihr zugeordneten angetriebenen Antriebsrolle, auf der sie anliegt, einen Transportspalt für den jeweiligen Bogen bildet, wobei die Anlage der wenigstens einen Transportrolle, vorzugsweise durch Verschwenkbarkeit der Achse der Transportrolle, bevorzugt verfedert, variieren kann.contraption for transporting bows, preferably printing material sheets, especially for a printing machine comprising at least one transport roller, preferably a pair of transport rollers on a common axis, which is preferred undriven, freely rotatably mounted and with an associated driven drive roller on which it rests, a transport gap for the forms respective arc, wherein the investment of at least one transport roller, preferably by pivoting the axis of the transport roller, preferably feathered, may vary.
Als
Stand der Technik wird nur beispielhaft auf die
Die Kraft, welche in der Vorrichtung auf den jeweiligen Bogen wirkt, ist vorzugsweise durch eine Feder vorgegeben. Hierdurch gibt es Medien, welche mit diesem System nur unzureichend funktionieren. Leichte Papiergrammaturen neigen zum Beispiel aufgrund einer zu hohen Kraft zum Knittern. Bei längeren Standzeiten drücken die Transportrollen bei einer hohen Kraft stark in die vorzugsweise darunter liegenden Antriebsrollen ein.The Force acting in the device on the respective arc, is preferably predetermined by a spring. There is this Media that only work inadequately with this system. light Paper grammages, for example, tend to be too strong to wrinkle. For longer Press lifetime the transport rollers at a high force strong in the preferably underlying drive rollers.
Schwere Papiergrammaturen werden dagegen bei einer zu niedrigen Kraft nicht mehr sicher transportiert. Eine geringe Kraft führt zu Problemen in Transportrichtung der Bögen und dadurch zum Beispiel zu Papierstaus. Im Extremfall werden verschwenkbare Transportrollen einfach durch zu steife Bögen angehoben, insbesondere wenn sie sich am Ausgang einer Bogenumlenkung befinden.severity Paper grammages, on the other hand, will not work if the force is too low transported more safely. A small force leads to problems in the transport direction the arches and thus, for example, to paper jams. In extreme cases, be swiveled Transport rollers simply lifted by too stiff bows, in particular when they are at the exit of a bend turn.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Anpassung der Kraft an die durch den jeweiligen Bogen bedingten Gegebenheiten zu ermöglichen.Of the Invention is therefore the object of an adjustment of the force to allow for the conditions caused by the respective bow.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Zusammenwirken einer mechanischen Feder zur Verfederung der Anlage der wenigstens einen Transportrolle und einer schalt- und/oder regelbaren bzw. steuerbaren elektromagnetischen Einrichtung.These The object is achieved by an interaction of a mechanical spring for springing the Plant of at least one transport roller and a switching and / or controllable or controllable electromagnetic device.
Aufgrund des Zusammenwirkens zwischen einer (relativ) konstanten Federkraft und einer zuschaltbaren und/oder variablen Magnetkraft, können die resultierenden Kraftverhältnisse erfindungsgemäß mit Vorteil den jeweiligen Bedürfnissen angepasst werden.by virtue of the interaction between a (relatively) constant spring force and a switchable and / or variable magnetic force, the resulting force ratios according to the invention with advantage the respective needs be adjusted.
Dabei kann die Feder insbesondere so vorinstalliert sein, dass die Feder die Transportrolle in Anlagerichtung belastet oder dass die Feder die Transportrolle entgegen der Anlagerichtung entlastet.there In particular, the spring may be pre-installed such that the spring loaded the transport roller in the direction of investment or that the spring relieves the transport roller against the direction of investment.
Die elektromagnetische Einrichtung kann dazu so installiert sein, dass sie der Federwirkung entgegenwirkt und/oder dass die elektromagnetische Einrichtung die Federwirkung verstärkt.The Electromagnetic device may be installed so that it counteracts the spring action and / or that the electromagnetic device reinforced the spring action.
Eine wahlweise Verstärkung oder Abschwächung der Federwirkung durch die elektromagnetische Einrichtung kann erfindungsgemäß nach einer Weiterbildung dadurch erreicht werden, dass die elektromagnetische Einrichtung in ihrer Wirkrichtung umkehrbar ist.A optional reinforcement or mitigation the spring action by the electromagnetic device according to the invention according to a development be achieved in that the electromagnetic device is reversible in their direction of action.
Eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung sieht vor, dass die elektromagnetische Einrichtung über einen Hebelmechanismus auf die Achse der Transportrolle wirkt.A preferred embodiment the device according to the invention provides that the electromagnetic device via a Lever mechanism acts on the axis of the transport roller.
Vorzugsweise ist vorgesehen, dass bei der elektromagnetischen Einrichtung der Strompuls und/oder die Eintauchtiefe eines Elektromagnetenkerns zur Änderung der Anlagekraft der Transportrolle variierbar ist.Preferably is provided that in the electromagnetic device of the Current pulse and / or the immersion depth of an electromagnet core to change the contact force of the transport roller is variable.
Des weiteren ist es bevorzugt vorgesehen, dass zu einem Anfahren der Vorrichtung aus dem Stand, die Anlagekraft der Transportrolle zunächst stärker einzustellen ist als im laufenden Betrieb danach.Of Further, it is preferably provided that to start the Device from the prior to initially adjust the contact force of the transport roller stronger is as on the fly afterwards.

Es zeigen:embodiments of the invention, from which further inventive features can result, but not limited to the scope of the invention, are shown in the drawing. Show it:
