Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Aus einem allgemeinen Stand der Technik herleitbare Lösungen der Schwierigkeiten, die durch Bandsäbel verursacht werden, sind z. T. sehr aufwendig und nachträglich schwer einbaubar und sie führen zuweilen nicht zu dem günstigen Ergebnis eines zwangfreien Bandeinlaufs und einer konstanten Bandbreite. Die Vorrichtung nach dem DE-GM 18 99 814, von der die Erfindung ausgeht, zeigt keine Lösung, da nur der Gesamtgrundrahmen ver schwenkbar ist.Solutions that can be derived from a general prior art the difficulties caused by band sabers are z. T. very complex and difficult to install afterwards and they sometimes do not lead to the favorable result of one easy tape entry and a constant bandwidth. The Device according to DE-GM 18 99 814, of which the invention runs out, shows no solution, since only the overall base frame ver is pivotable.
Der Erfindung liegt daher die Aufgabe zugrunde, die bekannte Vorrichtung so auszugestalten, daß säbelförmiges Band ohne Stauchung der Kanten bei deren einwandfreier Besäumung verar beitet werden kann.The invention is therefore based on the object, the known To design the device so that saber-shaped band without Process the edges when they are trimmed properly can be processed.
Die Lösung dieser Aufgabe ist in den Kennzeichen der Ansprüche beschrieben.The solution to this problem is in the characteristics of the claims described.
Anhand eines zeichnerisch dargestellten Beispieles wird die Erfindung nachstehend im einzelnen erläutert. Es zeigtUsing a graphically illustrated example, the Invention explained in detail below. It shows
Fig. 1 eine Draufsicht auf eine Vorrichtung gemäß der Erfindung als Prinzipskizze mit den wesentlichen Merkmalen beim Auftreten eines Bandsäbels mit einem Abweichungswinkel α S , Fig. 1 is a plan view of a device according to the invention as a principle sketch of the essential features of the occurrence of a band with a saber angle of deviation α S,
Fig. 2 eine perspektivische Ansicht einer
erfindungsgemäßen Vorrichtung.
Fig. 2 is a perspective view of a device according to the invention.
Das eine Problem, das erfindungsgemäß gelöst wird, besteht darin, daß das säbelförmig von dem Bandbund ablaufende Band sich seitlich in der Abwickeleinrichtung 1 verklemmt, oder die seitlichen Bandkanten-Führungsrollen (entsprechend den dargestellten Rollen 5 und 6) hinter der Abwickeleinrichtung 1 stauchen eine Bandkante auf, je nachdem, nach welcher Seite der Säbel ausweicht.The one problem that is solved according to the invention is that the saber-shaped tape running off the tape bundle is jammed laterally in the unwinding device 1 , or the lateral tape edge guide rollers (corresponding to the rollers 5 and 6 shown ) behind the unwinding device 1 compress a tape edge depending on which side the saber dodges.
Die Abwickeleinrichtung 1 ist auf der Schwenkplatte 2, die um den Drehzapfen 3, der in der Ebene der Bandkanten-Führungs rollen 5 und 6 liegt, schwenkbar angeordnet, und zwar auf der Grundplatte 4, die wiederum für sich seitlich verschiebbar ist.The unwinding device 1 is pivotally arranged on the pivot plate 2 , which roll around the pivot 3 , which roll in the plane of the band edge guide 5 and 6 , on the base plate 4 , which in turn is laterally displaceable.
Die beiden Bandkanten-Führungsrollen 5 und 6 messen den Druck, den das Band beim Ablauf ausübt. Wird nun die rechte Rolle 5 stark gepreßt, so läuft der Säbel mit einer rechtsgerichteten seitlichen Krümmung ein. In diesem Fall schwenkt die Abwickel einrichtung 1 z. B. mit Hilfe eines Stellzylinders 8 nach links, bis eine Übereinstimmung mit einem vorgewählten Seitendruck erzielt ist.The two tape edge guide rollers 5 and 6 measure the pressure that the tape exerts during the process. If the right roller 5 is now strongly pressed, the saber runs in with a right-hand lateral curvature. In this case, the unwinding device 1 z. B. with the help of an actuating cylinder 8 to the left until a match with a preselected side pressure is achieved.
Der Seitendruck kann durch Druckmeßdosen 7 in ähnlicher Weise gemessen werden. Im vorliegenden Fall bewirkt das Stellglied 8 das Verschwenken der Schwenkplatte 2 mit der Abwickeleinrich tung 1. Auf diese Weise ist gewährleistet, daß das Band zwang frei einläuft.The side pressure can be measured by pressure cells 7 in a similar manner. In the present case, the actuator 8 causes the pivoting of the pivot plate 2 with the Abwickeleinrich device 1st This ensures that the belt runs in freely.
Das wie beschrieben eingelaufene säbelige Band hat aber bis zum Einlauf in die Verformung zum Schraubennahtrohr noch ein anderes Problem zu überstehen.The saber-like band that has run in as described has up to for entry into the deformation to the screw seam tube to survive another problem.
Die Bandkantenbesäumung erfolgt gewöhnlich mit Hilfe von Kreismesserscheren 9 oder durch Fräs-Einheiten, die auf einer Tragplatte angeordnet sind. The band edge trimming is usually carried out with the help of circular knife shears 9 or by milling units which are arranged on a support plate.
Ein Fertigungsproblem tritt auf, wenn der Schrottstreifen 11, den z. B. die Kreismesser-Schere 9 abschneidet, durch den einlaufenden Säbel so schmal wird, daß ein einwand freier Schnitt nicht mehr gewährleistet ist oder das Band sogar ganz aus der Schere läuft, d. h. aus dem Kreismesser paar 9 einer Seite heraustritt. In diesem Fall wird auf der entgegengesetzten Seite der Schrottstreifen zu breit. Soll nun aber - wie fast immer - der Schrottstreifen zer kleinert werden, so treten Probleme in dem Zerhacker-System beider Seiten auf. Das bedeutet einen Stillstand der Gesamt- Anlage, d. h., Material- und Zeitverlust in beträchtlichem Umfang.A manufacturing problem occurs when the scrap strip 11 , the z. B. the circular knife scissors 9 cuts through the incoming saber so narrow that a perfect cut is no longer guaranteed or the tape even runs completely out of the scissors, ie from the circular knife pair 9 one side emerges. In this case, the scrap strip becomes too wide on the opposite side. However, if the scrap strip is to be shredded, as is almost always the case, problems occur in the chopper system on both sides. This means that the entire system comes to a standstill, ie a considerable loss of material and time.
Dieses Problem wird nun dadurch gelöst, daß die Schrott streifenbreite 11 z. B. einer Seite durch ein Meßgerät 10 laufend gemessen und überwacht wird. Über- oder unter schreitet die Breite des Schrottstreifens 11 die eingestell ten Werte, so wird die Grundplatte 4 auf dem Bandeinlaufrah men 14 verstellt, und zwar nach rechts, wenn der Schrottstreifen 11 der rechten Seite zu schmal wird, oder nach links, falls der rechte Schrottstreifen 11 zu breit wird.This problem is now solved in that the scrap strip width 11 z. B. one side is continuously measured and monitored by a measuring device 10 . Above or below the width below the scrap strip 11 which is values set, the base plate 4 is on the Bandeinlaufrah men adjusted 14, namely to the right when the scrap strip 11 is the right side too narrow, or to the left, if the right Scrap strip 11 becomes too wide.
Dadurch ist ein störungsfreier Produktionsablauf gewährleistet.This ensures a trouble-free production process.
