Abstract

The invention is intended to eliminate the problems encountered in the processing of sabre-shaped strips (strips with a lateral curvature). The invention eliminates the following problems: the lateral jamming in the uncoiling station (Fig. 2, Item 1), the compression of the strip-edge guide rollers (Items 5 and 6) and the risk that the strip will not run uniformly through the circular-blade shears (Item 9). The solution is as follows: The uncoiling station (Item 1) is of pivotable design. The pivot (Item 3) is situated in the plane of the strip edge guide rollers (Items 5 and 6). The base plate (Item 4), which supports the uncoiling station (Item 1) can be displaced sideways. Pivoting of the decoiling station (Item 1) with a predeterminable pressure on the strip-edge guide rollers (Items 5 and 6). Measurement of the width of the scrap strip (Item 11) of the circular-blade shears (Item 9). If the preselected width of the scrap strip is exceeded or undershot, the base plate (Item 4) with the uncoiling station is adjusted sideways in a corresponding manner. This gives a constant width of the scrap strip. Result: A trouble-free production process. Applications: In all helical-seam tube plants. <IMAGE>

Description

Verfahren zum Überwinden der Probleme eines Bandsäbels-Method of Overcoming the Problems of a Ribbon Saber

bei der Herstellung von Schraubennahtrohren Die Erfindung betrifft ein Verfahren zum Überwinden der Probleme eines Bandsäbels beim Einlauf eines gecoilten Bandes in eine Anlage zur Herstellung von Schraubennahtrohren. in the manufacture of screw sutures. The invention relates to a method of overcoming the problems of a ribbon saber running in a coiled one Tape in a plant for the production of screw sutures.

Bekannte 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.Known solutions to the difficulties caused by band sabers are sometimes very complex and difficult to install at a later date, and they lead sometimes not to the favorable result of an unconstrained strip infeed and one constant bandwidth.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Nachteile mit einer möglichst einfachen Konstruktion zu beheben.The invention is therefore based on the object of these disadvantages to fix the simplest possible construction.

Die Lösung dieser Aufgabe ist in den Ansprüchen beschrieben.The solution to this problem is described in the claims.

Anhand eines zeichnerisch dargestellten Beispieles wird die Erfindung nachstehend im einzelnen erläutert.The invention is based on an example shown in the drawing explained in detail below.

In der Zeichnung zeigen: Fig.1 eine Draufsicht auf eine Vorrichtung gemäß der Erfindung als Prinzipskizze mit den wesentlichen Merkmalen beim Auftreten eines Bandsäbels mit einem Abweichungswinkel (Alpha-s) und Fig.2 eine perspektivische Ansicht einer -erfindungsgemäßen Vorrichtung.The drawing shows: FIG. 1 a plan view of a device according to the invention as a schematic diagram with the essential features when it occurs a ribbon saber with an angle of deviation (alpha-s) and FIG. 2 a perspective View of a device according to the invention.

Das eine Problem, das erfindungsgemäß gelöst wird, besteht darin, daß das säbelförmig von dem Coil ablaufende Band sich seitlich in der Coilablauf-Station 1 verklemmt, oder die seitlichen Bandkanten-Ftihrungsrollen ((entsprechend den dargestellten Rollen 5 und 6) hinter der Entcoil-Station 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 unwinding tape from the coil is laterally in the coil unloading station 1 jammed, or the side belt edge guide rollers ((according to the illustrated Rolls 5 and 6) behind the decoiling station 1 compress a strip edge, depending on which side the saber dodges.

Die Entcoil-Station 1 ist nun im vorliegenden Fall auf der Schwenkplatte 2, die um den Drehzapfen 3, der in der Ebene der Bandkanten-Fffhrungsrollen 5 u.6 liegt, schwenkbar angeordnet und zwar auf der Grundplatte 4, die wiederum- für sich seitlich verschiebbar ist.The decoiling station 1 is now on the swivel plate in the present case 2, around the pivot 3, which is in the plane of the belt edge guide rollers 5 and 6 lies, pivotably arranged on the base plate 4, which in turn - for itself can be moved laterally.

Die beiden Bandkanten-Führungsrollen 5 und 6 messen den Druck, den das Band beim Ablauf susübt. Wird nun die rechte Rolle 5 stark gepreßt, so läuft der Säbel mit einer rechtsgerichteten seitlichen Krümmung ein.The two tape edge guide rollers 5 and 6 measure the pressure, the practicing the tape in the process. If the right roller 5 is now pressed hard, it runs the saber with a right-hand lateral curvature.

In diesem Fall schwenkt die Entcoil-Station 1 z.B. mit Hilfe eines Stellzylinders 8 nach links bis eine Übereinstimmung mit einem vorgewählten Seitendruck erzielt ist.In this case the decoiling station 1 swivels e.g. with the help of a Adjusting cylinder 8 to the left until a match with a preselected side pressure is achieved.

Der Seitendruck kann durch Druckmeßdosen 7 oder in ähnlicher Weise gemessen werden. Im vorliegenden Fall bewirkt das Stellglied 8 das Verschwenken der Schwenkplatte 2 mit der Entcoil-Station 1. Auf diese Weise ist gewährleistet, daß das Band zwangfrei einläuft.The side pressure can be measured by pressure cells 7 or in a similar manner be measured. In the present case, the actuator 8 causes the pivoting the swivel plate 2 with the decoiling station 1. This ensures that that the tape runs in without force.

Das wie beschriebene eingelaufene säbelige Band (solche ohne Säbel gibt es nichtl) hat aber bis zum Einlauf in die Verformung zum Schraubennahtrohr noch ein anderes Problem zu überstehen, Die Bandkantenbesäumung erfolgt gewöhnlich mit Hilfe von Kreismesser-Scheren 9 oder durch Fräs-Einheiten (nicht gezeichnet), die auf einer Tragplatte 13 angeordnet sind.The saber-like band worn in as described (those without sabers does not existl) but has up to the entry into the deformation to the screw suture tube yet another problem to overcome, the tape edge trimming is usually done with the help of circular knife scissors 9 or by milling units (not shown), which are arranged on a support plate 13.

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 einwandfreier Schnitt nicht mehr gewährleistet ist1 oder das Band sogar ganz aus der Schere läuft, d.h. aus dem Kreismesserpaar 9 einer Seite heraustritt.A manufacturing problem occurs when the scrap strip 11, the E.g. the circular knife scissors 9 cut off, so narrow due to the incoming saber becomes that a perfect cut is no longer guaranteed1 or the tape even runs completely out of the scissors, i.e. emerges from the pair of circular knives 9 on one side.

In diesem Fall wird auf der entgegengesetzten Seite der Schrottstreifen zu breit. Soll nun aber -wie fast immerder Schrottstreifen zerkleinert werden, so treten Probleme in dem Zerhacker-System beider Seiten auf.In this case, the scrap strip will be on the opposite side to wide. But if the scrap strip is to be shredded, as is almost always the case, so problems arise in the chopper system on both sides.

Das bedeutet einen Stillstand der Gesamt-Anlage, d.h., Material- und Zeitverlust in beträchtlichem Unfang.This means a standstill of the entire system, i.e., material and Considerable loss of time.

Dieses Problem wird nun dadurch gelöst, daß die Schrottstreifenbreite 11, z.B. einer Seite durch ein Meßgerät 10 laufend gemessen und überwacht wird. Über- oder unterschreitet die Breite des Schrottstreifens 11 die eingestellten Werte, so wird die Grundplatte 4 auf dem Bandeinlaufrahmen 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 by the fact that the scrap strip width 11, e.g. one side is continuously measured and monitored by a measuring device 10. If the width of the scrap strip 11 exceeds or falls below the set values, so the base plate 4 is adjusted on the tape inlet frame 14 and that to the right if the scrap strip 11 becomes too narrow to the right side, or to the left if the right scrap strip 11 is too wide.

Dadurch ist ein störungsfreier Produktionsablauf gewährleistet.This guarantees a trouble-free production process.
