Description
Die Erfindung betrifft ein Umlenkaggregat zum geführten Umlenken eines insbesondere aus Kunststoff bestehenden Bandes, insbesondere für eine ein Umreifungsaggregat umfassende Umreifungsmaschine zum Umlenken des Bandes in einem zwischen einem Bandspeicher und dem Umreifungsaggregat gelegenen Bereich.The invention relates to a deflection unit for guided deflection of a especially made of plastic tape, especially for a a strapping machine comprising deflection unit of the band in a between a band store and the strapping unit located area.
Wird ein solches Umlenkaggregat beispielsweise zwischen dem Umreifungsaggregat einer dem Umspannen des betreffenden Umreifungsgutes dienenden Umreifungsmaschine und einem beispielsweise als Rolle vorgesehenen Bandspeicher eingesetzt, so können je nach Ausführung, Position und/oder relativer Lage der Umreifungsmaschine und des Bandspeichers insbesondere auch unterschiedliche Bandumlenkwinkel erforderlich sein. Wird das Kunststoffband beispielsweise über eine Umlenkrolle geführt, so ergeben sich entsprechend unterschiedliche Umschlingungswinkel. Die bisher üblichen Umlenkaggregate sind nun aber in der Regel nur für einen oder einige wenige spezielle Anwendungsfälle geeignet. Sofern ein Umrüsten überhaupt möglich ist, ist dies in der Regel mit einem relativ großen Aufwand verbunden.Such a deflection unit, for example, between the strapping unit one is the reclamping of the strapping material in question serving strapping machine and one provided for example as a roll Tape storage used, depending on the version, position and / or relative position of the strapping machine and the belt store in particular, different belt deflection angles may also be required. If the plastic band is guided over a deflection roller, for example accordingly different wrap angles result. The deflection units that were customary up to now are generally only for one or a few special applications. If a changeover is possible at all, this is usually with a relatively large Associated effort.
Der Erfindung liegt die Aufgabe zugrunde, ein Umlenkaggregat der eingangs genannten Art zu schaffen, das bei möglichst einfach gehaltenem Aufbau problemlos insbesondere auch an unterschiedliche Gegebenheiten angepaßt werden kann. The invention has for its object a deflection unit of the beginning to create the type mentioned, while keeping it as simple as possible Easy to set up, especially in different circumstances can be adjusted.
Zur Lösung dieser Aufgabe umfaßt das Umlenkaggregat erfindungsgemäß eine Umlenkrolle, einen der Umlenkrolle vorgeschalteten Bandeinlaufkanal, einen der Umlenkrolle nachgeschalteten Bandauslaufkanal, wobei der Bandeinlaufkanal und der Bandauslaufkanal relativ zueinander verstellbar sind, und ein den Zwischenraum zwischen Bandeinlauf- und Bandauslaufkanal überbrückendes, dem Außenumfang der innenliegenden Umlenkrolle gegenüberliegendes äußeres flexibles Leitorgan.To achieve this object, the deflection unit comprises according to the invention a deflecting roller, a strip inlet duct upstream of the deflecting roller, one of the deflection roller downstream tape outlet channel, the The tape inlet channel and the tape outlet channel are adjustable relative to one another and the space between the tape inlet and tape outlet channel bridging the outer circumference of the inner Deflection roller opposite outer flexible guide element.

Dabei ist von Vorteil, wenn dieses flexible Leitorgan mit einem Ende an der Außenseite des Bandeinlaufkanals fixiert und mit seinem anderen Ende in den Bandauslaufkanal eingeführt ist. Je nach relativer Lage der beiden Bandlaufkanäle ragt das betreffende Bandende somit mehr oder weniger weit in den Bandauslaufkanal hinein. Die Länge des flexiblen Leitorgans ist so zu bemessen, daß dessen freies Ende auch bei maximaler Entfernung der beiden einander zugewandten Kanalenden noch in dem Bandauslaufkanal liegt. Damit ist bei sämtlichen Umlenk- bzw. Umschlingungswinkeln ausgeschlossen, daß das Band beim Einschieben an einer Kante anstößt.In a preferred practical embodiment, the flexible guide element is with one end at the tape inlet channel and with its other end supported on the tape outlet channel. It is an advantage if this flexible guide element with one end on the outside of the tape inlet channel fixed and inserted with its other end into the tape outlet channel is. Depending on the relative position of the two tape channels, the one in question protrudes The end of the strip is more or less far into the strip outlet channel inside. The length of the flexible guide element is to be dimensioned such that its free end even at maximum distance between the two facing channel ends is still in the tape outlet channel. So that is at all deflection or wrap angles excluded that the tape hits an edge when inserted.

It is thus possible, for example, for the tape inlet channel to adjust the use accordingly in different circumstances, the given position during each assignment to maintain however.
Dabei kann der Bandeinlaufkanal beispielsweise auf einer vorzugsweise mit der Achse der Umlenkrolle zusammenfallenden Achse schwenkbar gelagert und in seiner jeweiligen Schwenklage vorzugsweise fixierbar sein.In this case, the tape inlet channel can preferably be on, for example axis coinciding with the axis of the deflection roller stored and preferably be fixable in its respective pivot position.
Alternativ oder zusätzlich kann auch der Bandauslaufkanal relativ zur Umlenkrolle in verschiedene Positionen verstellbar sein. Dabei ist dieser Bandauslaufkanal aus den verschiedenen Positionen vorzugsweise jeweils entgegen einer Federkraft auslenkbar. Damit kann der Bandauslaufkanal Änderungen der Bandlaufrichtung, wie sie beispielsweise durch einen jeweiligen Umreifungsvorgang hervorgerufen werden, folgen.Alternatively or additionally, the tape outlet channel can also be relative to the The pulley can be adjustable in different positions. Here is this Tape outlet channel from the different positions preferably each deflectable against a spring force. So that the tape outlet channel Changes in the tape running direction, such as those caused by a particular one Strapping process follow.
Dabei kann der Bandauslaufkanal beispielsweise auf einer vorzugsweise mit der Achse der Umlenkrolle zusammenfallenden Achse schwenkbar gelagert und vorzugsweise federnd in seiner jeweiligen Schwenklage gehalten sein.

Alternativ oder zusätzlich kann auch der Bandauslaufkanal lösbar an einem solchen Träger befestigt sein. Der jeweilige Bandlaufkanal ist somit auswechselbar. Damit besteht beispielsweise die Möglichkeit, je nach Bedarf Elemente unterschiedlicher Länge zu verwenden.According to a preferred practical embodiment of the invention Deflection unit, the tape inlet channel is detachable on a carrier attached. Alternatively or additionally, the tape outlet channel can also be used be releasably attached to such a carrier. The respective tape run channel is therefore interchangeable.
