Description
"Bandzuführungsanlage für Schraubennaht-Rohrmaschinen""Tape feeding system for screw seam pipe machines"
Die Erfindung betrifft eine Bandzuführungsanlage für Schraubennaht-Rohrmaschinen, bei der jedes zur Verarbeitung gelangende Band, gleich welcher Breite, immer mit seiner geraden Bandkante unmittelbar dem 1. Punkt der Verschweißung zugluft, wobei di es er Punkt über der Drehachse zwischen Bandzuführungsanlage und Rohrformanlage liest und wo Bandabhaspel - Bandquerschweiß -Bandricht- und Ba!dförder-Station mit ihren Iviitten bandmittig zur Deckung kommen.The invention relates to a tape feed system for screw seam pipe machines, in which every tape to be processed, regardless of its width, is always included its straight band edge directly to the 1st point of the weld, whereby that is, the point above the axis of rotation between the strip feeding system and the tube forming system reads and where tape decoiler - tape cross welding - tape straightening and tape conveyor station with their ivies come to coincide in the middle of the band.
Us ist bekannt, bei Bandzuf:jhrungsanlagen wenigstens die -andförderstation zwecks Bandmittendeckung quer verstellbar anzuordnen. Eine solche Anoflnung ist sehr kostspielig, da allein schon wegen des hohen Kippmomentes große Kräfte in der Schlittenbahn zwecks Querverstellung aufgenommen werden müssen, so daß man sich für die übrigen Stationen mit außermittigem Banddurchlauf begnügen mußte. Die hierbei aftretenden unterschiedlichen Lagerbelastungen bzw. außermittigen Bandbelastungen versuchte man bei einigen Konstruktionen durch hydraulische Druckeinheiten auszusteuern, was wiederum aufwendig und sehr störanfällig ist.It is known that in the case of belt feeding systems, at least the -and conveyor station to be arranged transversely adjustable for the purpose of tape center coverage. One such suggestion is very costly, because of the high overturning moment alone, there are great forces in the Sledge track must be included for the purpose of transverse adjustment, so that you can had to be content with eccentric belt passage for the other stations. The one here Occurring different bearing loads or off-center belt loads Attempts were made in some constructions to be controlled by hydraulic pressure units, which in turn is complex and very prone to failure.
Der Erfindung liegt die Aufgabe zugrunde, alle für die Bandzuführungsanlage wichtigen Stationen zwecks Querverstellung zusammenzufassen.The invention is based on the object, all for the tape feed system summarize important stations for the purpose of lateral adjustment.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein gemeinsamer Unterbau die gewtinschten Stationen aufnimmt und der seinerseits auf dem Bandzuführungs-Grundrahmen quer zur Bandlaufrichtung verschoben werden kann.This object is achieved according to the invention in that a common Substructure accommodates the desired stations and that in turn on the tape feed base frame can be moved transversely to the direction of travel of the belt.
Der Unterbau kann zwecks einwandfreier Parallelverschi ebung in einer T-Nut-Führung mittels zweier Spindeln, die über gleichgeschaltete Getriebeeinheiten gleichförmig gedreht werden, bewegt werden.The substructure can ebung for the purpose of perfect Parallelverschi in a T-slot guidance by means of two spindles, which are connected via synchronized gear units rotated uniformly, moved.
Das iibliche BesLuffischerenpaar ½ann von der Zusammenfassung der Stationen auf dem Unterbau ausgenommen und auf dem Bandzufährungs-Grundrahmen ve der Rohrformungsanlage installiert werden.The usual visiting pair of shears from the summary of the Stations on the substructure excluded and on the belt feed base frame of the pipe forming line.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit einer einzigell Verstelloperation bei geringem konstruktivem Aufwand alle gewinschten Stationen mit einem Bruchteil des üblichen Zeitaufwandes auf jede beliebige Bandmitte eingestellt werden können. Kurze Umriist- und Einstellzeiten sind atsschlaggebend für die Wiitschaftlichkeit einer Schraubennaht-Rohrmaschine. Hierbei werden zudem die iLirDpmomente aufgrund des relativ langen Unterbaues in ihrer Auswirkung auf die T-Nut-Führung erheblich reduziert. Eine übliche se itenunters clii edliche hydraulische Druckaussteuerung der lagerungen einzelner Stationen entfällt.The advantages achieved with the invention are in particular: that with a single adjustment operation with little constructive effort all won stations with a fraction of the usual expenditure of time to any Mb can be adjusted. Short outline and setting times are essential for the economy of a screw seam pipe machine. Here are also the effect of the iLirDpmomente due to the relatively long substructure the T-slot guide is significantly reduced. A common side under the clii ed hydraulic There is no need for pressure control of the storage of individual stations.
Da die eine Bes iumschere des Bes;)umscherenl)aares nicht verstellt zu werden braucht (da sie immer auf der Linie der dem 1. Schweißpunkt zulaufenden geraden Bandkante steht) ist es zweckmäßig, das Besäumscherenpaar von der gemeinsamen Verstellung der Stationen auszunehmen und sie zwischen diesen und der Rohrformanlage zu installieren.Since one of the Bes iumschere des Bes;) umscherenl) aares does not adjust needs to be (because it always runs on the line of the 1st welding point straight band edge) it is advisable to separate the pair of trimming scissors from the common Excluding adjustment of the stations and placing them between these and the pipe forming line to install.
Ein ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden naher beschrieben.An exemplary embodiment of the invention is shown in the drawing and is described in more detail below.
Es zeigen Fig. 1 eine Seitenansicht einer Schraubennaht-Rohrmaschine Fig. 2 u. 3 je eine Draufsicht von Fig. 1 mit je einem in Verarbeitung befindlichen schmalen und einem breiten Band.1 shows a side view of a screw seam pipe machine 2 and 3 each show a top view of Fig. 1, each with one being processed narrow and one wide band.
Aus Fig. 1 bis 3 ist ersichtlich, wie ein Bandhaspel 1 in einer Bandabhaspel-Station 2 sich abspulen durch BaLndquerschweiß-tation 3, Bandricht-Station 4 und Bandförder-Station 5 hindurchlçuft, und diese Stationen alle eeinsam auf einem Unterbau 6 befestigt sind, der seinerseits in einer T-Nut-Führung 7 auf dem Bandzuführungs-Grundrahmen 8 mittels Spindeln 9, 10 parallel zu den Bandmitten 11 und 12 verstellt werdeii kann. Die Spindeln 9 und 10 können ihrerseits durch Getriebe 13 und 14, die zwecks Gleichlauf mit einer Welle 15 gekoppelt sind, angetrieben werden.From Fig. 1 to 3 it can be seen how a tape reel 1 in a tape decoiler station 2 unwind through strip cross welding station 3, strip straightening station 4 and belt conveyor station 5 runs through, and these stations are all attached to one another on a substructure 6 are in turn in a T-slot guide 7 on the tape feed base frame 8 by means of spindles 9, 10 parallel to the belt centers 11 and 12 werdeii can. The spindles 9 and 10 can in turn through Transmission 13 and 14, which are coupled to a shaft 15 for the purpose of synchronism, are driven.
Sowohl die gerade linke Bandkante 16 des schmalen Bandes 17 als auch die gerade linke Bandkante 18 des breiten Bandes 19 sind deckungsgleich und laufen durch den IittelpuzAt der Drehachse 20, über dem auch der 1. Punkt der Verschweißung 21 liegt.Both the straight left band edge 16 of the narrow band 17 and the straight left band edge 18 of the wide band 19 are congruent and run due to the IittelpuzAt of the axis of rotation 20, above which also the 1st point of the weld 21 lies.
Während die Rohrformstation 22 gewöhnlich fest auf dem Fundament 23 verankert ist, kann (z. B. bei erforderlichen unterschiedlichen Steigungswinkeln der Xohrwendel) um die Drehachse 20, auf Rollen 24 der Bandzuführungs-Grundrahmen 8 verschwenkt werden, wobei auf ihm auch zwei Besäumscheren 25 und 26 mit ihrem Schlittenunterbau 27 montiert sind.While the pipe forming station 22 is usually firmly on the foundation 23 is anchored, can (e.g. if different angles of inclination are required the coil) around the axis of rotation 20, on rollers 24 of the tape feed base frame 8 are pivoted, with two trimming shears 25 and 26 on it with their Carriage substructure 27 are mounted.
Hierbei braucht nur die Besäumschere 26 bei wechselnden Bandbreiten verstellt zu werden.In this case, only the trimming shear 26 is required with changing strip widths to be adjusted.
