Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Auflagern und Führen eines zu bearbeitenden Materialbandes, insbesondere von Nylon- oder Stahlcordbändern, im Bereich einer vom kontinuierlichen oder diskontinuierlichen Zuführ- oder Abtransport des Materialbandes mittels entsprechender Fördereinrichtungen herrührenden, sich abhängig vom diskontinuierlichen Zuführ- oder Abtransport in ihrer hängenden Lage ändernden Schlaufe des Materialbandes.The invention relates to a device for supporting and guiding material tape to be processed, especially nylon or steel cord tapes, in the range of a continuous or discontinuous feed or Removal of the material strip by means of appropriate conveying devices depends on the discontinuous supply or removal in their hanging position changing loop of the material band.
Im Rahmen der Herstellung oder Verarbeitung derartigen Bandmaterialien kommt es infolge des fördermäßig unterschiedlichen Zu- oder Abtransports des Bandmaterials unweigerlich zur Bildung einer hängenden Schlaufe, die zwischen dem Ende der Zuführeinrichtung und dem Anfang der Abtransporteinrichtung (in beiden Fällen handelt es sich im allgemeinen um Förderbänder) frei durchhängt und infolge der unterschiedlichen Kontinuität der Förderung ihre hängende Lage ändert. Infolge des freien Durchhängens jedoch kommt es infolge des Eigengewichts des Materialbandes im Schlaufenbereich zu einer Streckung des Materialbandes, was eine Breitenänderung zur Folge hat, aufgrund welcher sich zum einen die Materialeigenschaften ändern können,. zum andern können Fehler bei der Bearbeitung von beispielsweise bereits auf eine exakt bestimmte Länge zugeschnittenen Bandteilen auftreten.As part of the manufacture or processing of such strip materials it due to the different conveyance of the in or out transport of the strip material inevitably to form a hanging loop between the end the feeding device and the beginning of the removal device (in both Cases are generally conveyor belts) slack and consequent the different continuity of funding changes their hanging situation. As a result of the free sagging, however, it occurs due to the dead weight of the Material tape in the loop area to stretch the material tape what results in a change in width due to which the material properties change can change. on the other hand, errors in processing from, for example, already cut to a precisely defined length Band parts occur.
Um diese'Schwierigkeiten zu vermeiden, ist in der DE 44 11 936 C2 bereits ein Unterstützungstransportband vorgeschlagen worden, welches das eigentliche Materialband im Schlaufenbereich, zumindest im Bereich der Schlaufensenke, unter Bildung einer Unterstützungsschlaufe trägt. Das Unterstützungstransportband wird dabei so angetrieben, daß sich die Transportbandschlaufe synchron mit der Materalschlaufe ändert und die Materialbandschlaufe daher in jeder Lage auf der Unterstützungstransportbandschlaufe aufgelagert ist.In order to avoid these difficulties, DE 44 11 936 C2 already contains a Support conveyor belt has been proposed, which is the actual one Material band in the loop area, at least in the area of the loop depression, wearing a support loop. The support conveyor belt is driven so that the conveyor belt loop is synchronized with the material loop changes and therefore the material band loop in any position the support conveyor belt loop is supported.
Diese Anordnung ist jedoch relativ kompliziert ausgebildet, teuer in der Herstellung und anfällig im Betrieb. However, this arrangement is relatively complicated, expensive to manufacture and vulnerable in operation.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszugestalten, daß mit einfachen Mitteln irreversible Änderungen der Länge und/oder Breite des Materialbandes vermieden werden können.The invention is therefore based on the object of a device at the outset mentioned type so that with simple means irreversible changes the length and / or width of the material band can be avoided.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß das Materialband über, die Schlaufe in zwei Teilschlaufen unterteilende, kontinuierlich mit der Abtransporteinrichtung rotierend angetriebene Beruhigungsrollen, insbesondere in Form einer Beruhigungstrommel mit großem Durchmesser, vorzugsweise oberhalb 350 mm, geführt ist.To solve this problem, the invention provides that the material band over, dividing the loop into two partial loops, continuously with the Removal device, rotatingly driven calming rollers, in particular in the form of a large diameter calming drum, preferably above 350 mm, is guided.
Durch die erfindungsgemäße Ausbildung bildet sich zwischen der Zuführeinrichtung der Beruhigungstrommel eine sich in ihrer Länge entsprechend der meist diskontinuierlichen Zuführung ändernde Schlaufe aus, innerhalb derer tatsächlich Längungen des Materialbandes auftreten. Die zwischen der Beruhigungstrommel und der Abtransporteinrichtung liegende Beruhigungsschlaufe konstanter Länge führt aber überraschenderweise dazu, daß sich diese Längungen vollständig oder zumindest weitestgehend wieder zurückbilden, so daß auf der Abtransporteinrichtung das Materialband wieder in der Form vorliegt, wie es von der Zuführeinrichtung angeliefert wird.The inventive design forms between the feed device the calming drum is one in length corresponding to the most discontinuous feed changing loop, within which actually Elongations of the material band occur. The one between the calming drum and the calming loop of constant length lying on the removal device surprisingly, however, leads to these elongations being complete or at least largely regress, so that on the removal device the material band is again in the form as it is from the feed device is delivered.
In Ausgestaltung der Erfindung kann dabei auch vorgesehen sein, daß die Beruhigungsrollen die Umlenkrollen einer Förderbandstrecke bilden, d.h. zwischen der Vorratsschlaufe und der Beruhigungsschlaufe ist eine im wesentlichen horizontale Förderbandstrecke eingeschaltet.In an embodiment of the invention it can also be provided that the calming rollers form the deflection rollers of a conveyor belt section, i.e. between the The supply loop and the calming loop is an essentially horizontal one Conveyor belt section switched on.
Bevorzugt soll die zwischen der Beruhigungstrommel und der Abtransporteinrichtung liegende Beruhigungsschlaufe nur kurz ausgebildet sein, also nur wenig durchhängen, und darüber hinaus soll.die Beruhigungstrommel näher bei der Abtransporteinrichtung als bei der Zuführeinrichtung angeordnet sein. Durch diese relativ kleine Beruhigungsschlaufe ist deren Gewicht auch entsprechend klein, so daß hier nicht nur keine unerwünschten Längungen aufgrund eines hohen Gewichts der Schlaufe auftreten können, sondern im Gegenteil sogar die vorstehend angesprochene Rückbildung der Längungen, die zwischen der Zuführeinrichtung und der Beruhigungstrommel aufgetreten sind, stattfinden kann.Preferably between the calming drum and the removal device lying calming loop should be designed only briefly, so only a little sag, and moreover, the calming drum should be closer to the removal device than be arranged in the feed device. Through this relatively small calming loop, its weight is correspondingly small, so that here not only no unwanted elongations due to high weight the loop can occur, on the contrary, even the above mentioned regression of the elongations between the feeder and the calming drum has occurred can take place.

- Fig. 2
- eine Seitenansicht einer abgewandelten Vorrichtung, bei der die Beruhigungstrommel durch eine Förderbandstrecke ersetzt ist.

Die Figur 1 zeigt eine Spleißvorrichtung 1, von der das gespleißte Materialband 2,
beispielsweise ein Nylon- oder Stahlcordband, über eine als Förderband ausgebildete
Zuführeinrichtung 3 normalerweise über eine hängende Schlaufe 4 oberhalb
einer Grube 5 an eine Abtransporteinrichtung 6 übergeben wird, die, ebenfalls
bevorzugt . als Transportband ausgebildet, kontinuierlich angetrieben wird.
Infolge der durch das Anhalten des Bandes zum Spleißen diskontiuierlichen Zuführung
über die Zuführeinrichtung 3 ändert sich normalerweise die Länge der
Schlaufe 4 beim Zuführen, die demzufolge stärker nach unten hängt. Während
der Phasen, in denen die Zuführeinrichtung 3 entsprechend dem Spleißvorgang in
der Spleißeinrichtung 1 angehalten ist, wird durch die kontinuierliche Weiterförderung
der Abtransporteinrichtung 6 die Länge der durchhängenden Schlaufe 4 geringer.FIG. 1 shows a splicing device 1, of which the
Um Veränderungen der Bandlänge und der Bandbreite durch das hohe Gewicht
der durchhängenden Schlaufe 4 zu vermeiden, ist erfindungsgemäß eine Beruhigungstrommel
7 vorgesehen, über die das Materialband 2 geführt und dadurch in
zwei Teilschlaufen, nämlich die Vorratsschlaufe 8 und eine Beruhigungsschlaufe
9, unterteilt wird. Die Vorratsschlaufe 8 ändert ihre Länge in gleicher Weise, wie
dies bei der herkömmlichen einteiligen Schlaufe 4 der Fall war, während die Länge
der Beruhigungsschlaufe 9 gleich bleibt, da die Beruhigungstrommel 7 mit gleicher
kontinuierlicher Geschwindigkeit angetrieben wird wie die Abtransporteinrichtung
6. Die Beruhigungstrommel mit ihrer Antriebsvorrichtung 10 ist dem Beginn
der Abtransporteinrichtung 6 näher beabstandet als dem Ende der Zuführeinrichtung
3. Dadurch kann sich zum einen eine große Vorratsschlaufe 8 ausbilden und
zum andern ergibt sich nur eine relativ kleine Beruhigungsschlaufe 9. Diese Ausbildung
wiederum hat zur Folge, daß sich in der Beruhigungsschlaufe 9 mit geringem
Gewicht und kontinuierlicher Länge eine Rückbildung der Längungen ausbilden
kann, die unweigerlich in der Vorratsschlaufe 8 stattgefunden haben. Diese
Rückbildung kann dabei so weit gehen, daß das Materialband 2 auf der Abtransporteinrichtung
6 in identisch gleicher Länge und Breite, also im gleichen Zustand,
abtransportiert wird, in dem es von der Zuführeinrichtung 3 in die Vorratsschlaufe
8 eingebracht worden ist.To change the length and bandwidth of the band due to the high weight
To avoid the sagging loop 4 is a calming drum according to the invention
7 provided over which the
Dabei hat es sich. gezeigt, daß die Rückbildung von Längungen besonders günstig durch eine Erhöhungdes. Durchmessers der Beruhigungstrommet 7 beeinflußt werden kann, die demzufolge einen Mindestdurchmesser von etwa 350 mm aufweisen sollte.It did. shown that the regression of elongations is particularly favorable by increasing the. Diameter of the calming stream 7 is affected can be, which consequently have a minimum diameter of about 350 mm should.
Die Ausführungsform nach Fig 2 unterscheidet sich von der nach Fig. 1 lediglich
dadurch, daß anstelle einer Beruhigungstrommel 7 zwei die Umlenkrollen eines
Förderbandes 11 bildende Beruhigungsrollen 12 vorgesehen sind. Die Vorratsschlaufe
8 und die Beruhigungsschlaufe 9 werden also nicht von einer einzelnen
Trommel getrennt, sondern einer im Prinzip beliebig langen Förderbandstrecke.The embodiment according to FIG. 2 only differs from that according to FIG. 1
characterized in that instead of a calming drum 7 two the pulleys one
