In der DE-A-33 00 039 ist ein Umlenkaggregat dieser Art offenbart, das eine Umlenkrolle, einen dieser vorgeschalteten, an einem Rahmen ortsfest angebrachten Bandeinlaufkanal sowie einen der Umlenkrolle nachgeschalteten Bandauslaufkanal aufweist. Der Bandauslaufkanal ist an seinem einen Ende mittels eines Stiftes schwenkbar am Rahmen gelagert und wird bei Bandspannungsänderungen durch das hindurchlaufende Band verschwenkt und damit in seiner Lage bezüglich des ortsfesten Bandeinlaufkanals verändert. Diese Schwenkbewegung des Bandauslaufkanals wird zum Detektieren der Bandspannung verwendet. Zur Führung des Bandes sind zwischen dem Bandeinlauf- und dem Bandauslaufkanal Führungsrollen angeordnet, die dem Aussenumfang der innen liegenden Umlenkrolle gegenüber liegen. Das Umlenkaggregat ist zwischen dem Umreifungsaggregat einer Umreifungsmaschine und einem als Bandspule ausgebildeten Bandspeicher angeordnet und ist nur für die gegebene räumliche Anordnung von Bandspeicher und Umreifungsaggregat und nur für den gegebenen Umlenkungswinkel des über die Umlenkrolle geführten Bandes ausgelegt. In DE-A-33 00 039 a Umlenkaggregat this type discloses a pulley, one of these upstream, attached to a frame fixed Bandeinlaufkanal and one of the deflection roller having downstream strip outlet channel. Of the Bandauslaufkanal is at one end by means of a Pen pivotally mounted on the frame and is at Tape tension changes by the passing tape pivoted and thus in its position regarding the Fixed band inlet channel changed. These Pivoting movement of the belt outlet channel becomes detectable used the tape tension. To guide the band are between the Bandeinlauf- and the belt outlet channel Guide rollers arranged, which are the outer circumference of the inside lying opposite pulley. The deflection unit is between the Umreifungsaggregat a Strapping machine and trained as a reel Tape storage is arranged and is only for the given spatial arrangement of tape storage and Strapping unit and only for the given Deflection angle of the guided over the pulley belt designed.

Aufgrund dieser Ausbildung kann das Umlenkaggregat schnell und problemlos an unterschiedliche Gegebenheiten angepasst werden, wobei unabhängig von der jeweiligen relativen Lage der beiden in verschiedene Schwenklagen verstellbaren Bandlaufkanäle bzw. unabhängig vom jeweiligen Umschlingungswinkel, über den das Band über die Umlenkrolle geführt werden muss, stets eine zuverlässige Bandführung gewährleistet ist. Nachdem das Leitorgan flexibel ist, passt es sich automatisch an die jeweilige relative Lage der beiden Bandlaufkanäle an, so dass in jedem Fall für eine optimale Überbrückung des Zwischenbereiches und eine entsprechend zuverlässige Bandführung gesorgt ist.Due to this design, the Umlenkaggregat can quickly and easily adapted to different circumstances regardless of the relative position the two adjustable in different pivoting positions Bandlaufkanäle or independently of the respective Wrap angle over which the band over the Guide roller must be guided, always a reliable Tape guide is guaranteed. After the guiding organ flexible, it automatically adapts to the respective one relative position of the two tape channels, so that in in any case for an optimal bridging of the Zwischenbereiches and a correspondingly reliable Tape guide is taken care of.

Bei einer bevorzugten praktischen Ausführungsform ist das flexible Leitorgan, das vorzugsweise durch ein Leitblech gebildet ist, mit einem Ende am Bandeinlaufkanal und mit seinem anderen Ende am Bandauslaufkanal abgestützt. 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 im Bandauslaufkanal liegt. Damit ist bei sämtlichen Umlenk- bzw. Umschlingungswinkeln ausgeschlossen, dass das Band beim Einschieben an einer Kante anstößt.In a preferred practical embodiment, this is flexible guide member, preferably by a baffle is formed, with one end on Bandeinlaufkanal and with its other end supported on the belt outlet channel. there is advantageous if this flexible baffle with a End fixed to the outside of the tape inlet channel and with its other end inserted into the belt outlet channel is.

The length of the flexible Leitorgans is to be measured so that its free end even at maximum distance of the two each other facing channel ends is still in the belt outlet channel. This is at all Umlenk- or wrap angles excluded that the tape when inserting on a Edge abuts.

Bei einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Umlenkaggregats ist der relativ zur Umlenkrolle in verschiedene Schwenklagen verstellbare Bandeinlaufkanal in diesen Schwenklagen jeweils fixierbar. Es ist somit möglich, den Bandeinlaufkanal für den Einsatz bei unterschiedlichen Gegebenheiten entsprechend zu verstellen, während eines bestimmten Einsatzes dessen jeweils vorgegebene Schwenklage jedoch beizubehalten.In a convenient practical embodiment of the Umlenkaggregats invention is relative to Deflection pulley adjustable in various pivoting positions Bandeinlaufkanal in each of these pivotal positions can be fixed. It is thus possible to use the tape entry channel for use in different circumstances accordingly adjust, during a particular use of However, to maintain each predetermined pivotal position.

Alternativ oder zusätzlich kann der ebenfalls relativ zur Umlenkrolle in verschiedene Schwenklagen verstellbare Bandauslaufkanal federnd in seiner jeweiligen Schwenklage gehalten und aus den verschiedenen Schwenklagen jeweils entgegen einer Federkraft auslenkbar sein. Damit kann der eandauslauf kanal Änderungen der Bandlaufrichtung, wie sie beispielsweise während eines Umreifungsvorganges auftreten können, folgen. Alternatively or additionally, the also relative to Deflection pulley adjustable in various pivoting positions Band outlet channel resiliently in its respective pivot position held and from the different pivotal positions respectively be deflectable against a spring force. This can be the eandauslauf channel changes the tape direction, as they For example, occur during a strapping process can, follow.

Gemäß einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Umlenkaggregats ist der Bandeinlaufkanal lösbar an einem Träger befestigt. Alternativ oder zusätzlich kann auch der Bandauslaufkanal lösbar an einem solchen Träger befestigt sein. Der jeweilige Bandlaufkanal ist somit auswechselbar.

Die Figuren 1 bis 4 zeigen in rein schematischer Darstellung ein Umlenkaggregat 10 zum geführten Umlenken eines beispielsweise aus Kunststoff bestehenden Bandes 12.Figures 1 to 4 show a purely schematic representation of a deflection unit 10 for guided deflection of a plastic, for example existing volume 12.

Ein solches Umlenkaggregat 10 ist insbesondere für eine ein Umreifungsorgan 14 umfassende, in der Figur 5 dargestellte Umreifungsmaschine 16 geeignet. In diesem Fall kann das Umlenkaggregat 10 insbesondere in dem zwischen einem Bandspeicher 18 und dem Umreifungsaggregat 14 gelegenen Bereich angeordnet sein.Such a deflection unit 10 is in particular for a strapping 14 comprehensive, shown in Figure 5 strapping machine 16th suitable.

Wie anhand der Figuren 1 bis 4 zu erkennen ist, umfaßt das Umlenkaggregat eine Umlenkrolle 20, einen der Umlenkrolle 20 vorgeschalteten Bandeinlaufkanal 22 und einen der Umlenkrolle 20 nachgeschalteten Bandauslaufkanal 24. Der Bandeinlaufkanal 22 und der Bandauslaufkanal 24 sind relativ zueinander verstellbar.As can be seen from Figures 1 to 4, comprises the deflection unit a deflection roller 20, one of the deflection roller 20 upstream Bandeinlaufkanal 22 and one of the guide roller 20 downstream Belt outlet channel 24. The belt inlet channel 22 and the belt outlet channel 24 are adjustable relative to each other.

Darüberhinaus umfaßt dieses Umlenkorgan 10 ein den Zwischenraum zwischen Bandeinlauf- und Bandauslaufkanal 22 bzw. 24 überbrückendes, dem Außenumfang der innenliegenden Umlenkrolle 20 gegenüberliegendes äußeres flexibles Leitorgan, das im vorliegenden Fall durch ein flexibles Leitblech 26 gebildet ist.In addition, this deflecting member 10 includes a gap between Bandeinlauf- and belt outlet channel 22 and 24 bridging, the outer circumference of the inner guide roller 20 opposite outer flexible guide element, which in the present case by a flexible Guide plate 26 is formed.

Wie sich insbesondere aus der Figur 4 ergibt, besitzt die Umlenkrolle 20 eine Umfangsnut 28, in der das Kunststoffband 12 entsprechend geführt ist. In dem Bereich zwischen den beiden Bandlaufkanälen 22, 24 ist die Umfangsnut 28 durch das flexible Leitblech 26 abgedeckt, so daß das Kunststoffband 12 zuverlässig zwischen dem Boden der Nut 28 und diesem Leitblech 26 geführt, d.h. innerhalb der Umfangsnut 28 gehalten ist. As can be seen in particular from FIG. 4, the deflection roller 20 has a circumferential groove 28, in which the plastic strip 12 is guided accordingly is. In the area between the two tape channels 22, 24 is the Circumferential groove 28 covered by the flexible baffle 26, so that the Plastic band 12 reliably between the bottom of the groove 28 and this Guide plate 26 out, i. is held within the circumferential groove 28.

Wie anhand der Figuren 1 und 2zu erkennen ist, kann sich das flexible Leitblech 26 zumindest in seinem mittleren Bereich in die Umfangsnut 28 hinein erstrecken.As can be seen from Figures 1 and 2, the flexible Guide plate 26 at least in its central region in the circumferential groove 28th extend into it.

Beim vorliegenden Ausführungsbeispiel ist die Umlenkrolle 20 drehbar auf einer Achse 30 gelagert, die drehfest an einem Befestigungsarm 32 angebracht ist. Im vorliegenden Fall ist dieser Befestigungsarm 32 seitlich angeordnet. Grundsätzlich kann dieser beispielsweise jedoch auch oben oder unten angeordnet sein.In the present embodiment, the guide roller 20 is rotatable mounted on an axis 30, the rotationally fixed to a mounting arm 32nd is appropriate. In the present case, this attachment arm 32 is laterally arranged. Basically, this example, but also above or arranged below.

Das flexible Leitblech 26 ist mit einem Ende 34 am Bandeinlaufkanal 22 und mit seinem anderen Ende 36 am Bandauslaufkanal 24 abgestützt. Dabei ist das flexible Leitblech 26 mit dem einen Ende 34 durch Befestigungsmittel 38 an der Außenseite des Bandeinlaufkanals 22 fixiert und mit seinem anderen, freien Ende 36 in den Bandauslaufkanal 24 eingeführt.The flexible baffle 26 is connected to one end 34 at the band inlet channel 22nd and supported with its other end 36 on the belt outlet channel 24. In this case, the flexible guide plate 26 with one end 34 by fastening means 38 fixed to the outside of the band inlet channel 22 and with its other, free end 36 inserted into the belt outlet channel 24.

Der Bandeinlaufkanal 22 ist relativ zur Umlenkrolle 20 in verschiedene Positionen verstellbar und in diesen vorzugsweise jeweils fixierbar. Dazu ist der Bandeinlaufkanal 22 an einem Träger 40 angebracht, der auf der drehfesten Achse 30 schwenkbar gelagert und beispielsweise über eine Klemmschraube 42 in seiner jeweiligen Schwenklage fixierbar ist. In den Figuren 1 und 2 sind drei verschiedene Schwenklagen 22, 22', 22'' des Bandeinlaufkanals 22 dargestellt.The tape inlet channel 22 is relative to the guide roller 20 in different Adjustable positions and in these preferably each fixable. To the Bandeinlaufkanal 22 is mounted on a support 40 which on the rotatably mounted axis 30 pivotally mounted and, for example via a Clamping screw 42 is fixable in its respective pivot position. In the Figures 1 and 2 are three different pivotal positions 22, 22 ', 22' 'of Bandeinlaufkanals 22 shown.

Auch der Bandauslaufkanal 24 ist relativ zur Umlenkrolle 20 in verschiedene Positionen verstellbar. Aus diesen einstellbaren, vorgebbaren Positionen ist der Bandauslaufkanal 24 vorzugsweise jeweils entgegen einer Federkraft auslenkbar. Dazu ist der Bandauslaufkanal 24 an einem Träger 44 angebracht, der auf der drehfesten Achse 30 schwenkbar gelagert und vorzugsweise federnd in einer vorgebbaren Schwenklage gehalten ist.Also, the belt outlet channel 24 is relative to the guide roller 20 in different Adjustable positions. From these adjustable, predefinable positions the belt outlet channel 24 is preferably opposite to one Spring force deflectable. For this purpose, the belt outlet channel 24 on a support 44 mounted pivotally mounted on the rotationally fixed axis 30 and is preferably held resiliently in a predeterminable pivot position.

Beim vorliegenden Ausführungsbeispiel ist zwischen dem dem Bandauslaufkanal 24 zugeordneten Träger 44 und einem auf der Achse 30 verstellbaren Klemmteil 46 (vgl. insbesondere die Figuren 2 bis 4) eine Zugfeder 48 vorgesehen, durch die der Träger 44 und damit der Bandauslaufkanal 24 federnd in der jeweils eingestellten vorgegebenen Schwenklage gehalten wird. Die jeweils gewünschte Schwenkausgangslage des Bandauslaufkanals 24 kann durch ein entsprechendes Verstellen des Klemmteils 46 auf der drehfesten Achse 30 eingestellt werden. Aus dieser eingestellten Ausgangsschwenklage kann der Bandauslaufkanal 24 dann entgegen der Kraft der Zugfeder 48 ausgelenkt werden, so daß er Laufrichtungsänderungen des Kunststoffbandes 12, wie sie beispielsweise bei einem Umreifungsvorgang auftreten, folgen kann. Wie am besten anhand der Figur 3 zu erkennen ist, ist an dem Träger 44 sowie an dem Klemmteil 46 jeweils ein Zapfen 50 bzw. 52 vorgesehen, an dem ein jeweiliges Ende der Zugfeder 48 eingehängt ist.In the present embodiment is between the belt outlet channel 24 associated carrier 44 and one on the axis 30 adjustable Clamping part 46 (see in particular Figures 2 to 4) a tension spring 48 provided by the carrier 44 and thus the belt outlet channel 24 resiliently in the respective preset pivot position is held. The respective desired pivoting output position of the belt outlet channel 24 can by a corresponding adjustment of the clamping part 46 are set on the rotationally fixed axis 30. Off this set Output pivot position, the belt outlet channel 24 then counter the force of the tension spring 48 are deflected so that it changes direction of travel the plastic strip 12, as for example in a Strapping process can occur, follow. As best of all 3 can be seen on the carrier 44 and on the clamping part 46 each have a pin 50 and 52, respectively, at which a respective end the tension spring 48 is mounted.

In den Figuren 1 und 2 sind drei unterschiedliche, über das Klemmteil 46 einstellbare Ausgangspositionen 24, 24', 24'' des Bandauslaufkanals dargestellt.In FIGS. 1 and 2, there are three different ones, via the clamping part 46 adjustable starting positions 24, 24 ', 24' 'of the belt outlet channel shown.

Die beiden Bandlaufkanäle 22, 24 können beispielsweise jeweils durch ein geschlossenes Profil gebildet sein. The two tape running channels 22, 24 can each, for example, by a be formed closed profile.

Der Bandeinlaufkanal 22 ist durch Befestigungsmittel 54 lösbar an dem zugeordneten Träger 40 befestigt. Entsprechend ist auch der Bandauslaufkanal 24 durch Befestigungsmittel 56 lösbar an dem zugeordneten Träger 44 befestigt. Die beiden Bandlaufkanäle 22, 24 sind somit auswechselbar. Damit können je nach Bedarf Elemente unterschiedlicher Länge verwendet werden.The tape inlet channel 22 is releasably secured by fastening means 54 on the associated carrier 40 attached.
