Description

Längsdrahtführung zum Vorschub einer Schar paralleler Stahldrähte Longitudinal wire guide for feeding a group of parallel steel wires

Die Erfindung betri f ft eine Längsdrahtführung zum Vorschub einer Schar paralleler Stahldrähte in eine vorgegebene X-Rich- tung . The invention relates to a longitudinal wire guide for advancing a group of parallel steel wires in a predetermined X direction.

Stand der Technik bei der Herstellung von Industriegittern und Bewehrungsmatten ( z . B . Zaungitter, Estrichgitter ) in automatisierten Schweißmaschinen mit auf Länge geschnittenen Drähten ist ein einlauf seif iges Vorschubsystem, eine einlauf seif ige Drahtführung und ein auslauf seif iges Vorzugsystem. Bisher werden einer Maschine einlaufseitig Längsdrähte zugeführt , wobei feststehende Führungselemente den Abstand der Längsdrähte einer Mattenebene untereinander festlegen . Lösungen dieser Art sind nachteilig, weil sie nicht oder nur schwer verstellbar oder anpassbar sind . The state of the art in the production of industrial mesh and reinforcement mats (e.g. fence mesh, screed mesh) in automated welding machines with wires cut to length is an inlet soapy feed system, an inlet soapy wire guide and an outlet soapy feed system. Up until now, longitudinal wires have been fed to a machine on the inlet side, with fixed guide elements determining the distance between the longitudinal wires of a mat plane. Solutions of this type are disadvantageous because they are difficult or impossible to adjust or adjust.

Aufgabe der Erfindung ist es , eine Schar von Längsdrähten schnell und genau taktweise in Richtung einer Schweißmaschine zu transportieren und dabei eine ausreichend genaue und schnelle Verstellbarkeit des Abstandes der Längsdrähte untereinander zu ermöglichen . The object of the invention is to transport a group of line wires quickly and precisely in cycles in the direction of a welding machine and to enable the distance between the line wires to be adjusted with sufficient precision and speed.

Die erfindungsgemäße Längsdrahtführung erreicht dies dadurch, dass sie eine Viel zahl von Garnituren aufweist , bestehend aus unterem Längsdraht führungshebel ( LD-Führungshebel ) , oberem Längsdraht führungshebel ( LD-Führungshebel ) , zwischen beiden wirkender Druckfeder sowie mit einer seitlichen Längsdraht füh- rung ( LD-Führung) , wobei die Garnituren stufenlos in einer senkrecht zur X-Richtung liegenden Y-Richtung zueinander ver- schieblich angeordnet sind, und wobei die Viel zahl von Garnituren auf einem Wagen angeordnet sind, der in X-Richtung antreibbar ist . The line wire guide according to the invention achieves this by having a large number of sets, consisting of a lower line wire guide lever (LD guide lever), an upper line wire guide lever (LD guide lever), a compression spring acting between the two and a lateral line wire guide (LD -leadership), wherein the sets can be continuously adjusted to one another in a y-direction perpendicular to the x-direction are arranged to be slidable, and the multiplicity of sets are arranged on a carriage which can be driven in the X-direction.

In einer Aus führungs form sind die Viel zahl von Garnituren gemeinsam auf einem Rahmen angeordnet , auf welchem sie gemeinsam in einer Z-Richtung, die im Wesentlichen senkrecht zur Y-Rich- tung und zur X-Richtung liegt , mittels einer Höhenverstellung anhebbar und senkbar sind . In one embodiment, the multitude of sets are arranged together on a frame, on which they can be raised and lowered together in a Z-direction, which is essentially perpendicular to the Y-direction and to the X-direction, by means of a height adjustment are .

Zusätzlich sind der Antrieb des Wagens und ein Schließen der unteren LD-Führungshebel sowie der oberen LD-Führungshebel durch eine Steuerung taktbar, um eine Schar paralleler Stahldrähte in wiederholten Schritten in X-Richtung zu transportieren . In addition, the drive of the carriage and a closing of the lower LD guide levers and the upper LD guide levers can be clocked by a controller in order to transport a group of parallel steel wires in repeated steps in the X direction.

Es ist ebenso denkbar, dass der der Antrieb des Wagens elektrisch, pneumatisch oder hydraulisch erfolgt . It is also conceivable that the carriage is driven electrically, pneumatically or hydraulically.

Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Aus führungsbeispiels näher erläutert . Es zeigen : Fig . 1 eine Seitenansicht einer Garnitur für den Längsdraht- vorschub, Fig . 2 eine schematische Seitenansicht eines Längs- drahtvorschubs und Fig . 3 eine Vorderansicht einer Reihe von Garnituren für den Längsdrahtvorschub . The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawings. Shown are : Fig . 1 is a side view of a set for the line wire feed, FIG. 2 shows a schematic side view of a line wire feed and FIG. 3 is a front view of a series of line wire feeder assemblies.

Wie in Fig . 1 und 2 gezeigt , besteht ein Längsdrahtvorschub aus einem feststehenden Grundgestell 1 mit einem in der Höhe ( Z-Richtung) verstellbaren Rahmen 2 , in dem ein in X-Richtung bewegbarer Vorzugswagen bzw . Wagen 3 mit den seitlichen Längs- draht führungen 10 samt Hebeln ( siehe unten) sitzt , der dieAs in Fig. 1 and 2, a line wire feeder consists of a fixed base frame 1 with a height-adjustable (Z-direction) frame 2, in which a priority carriage or Carriage 3 with the lateral longitudinal wire guides 10 including levers (see below) sits, which the

Längsdrähte 6 in X-Richtung in eine Schweißmaschine (nicht dargestellt ) befördert . Die Längsdrähte ( LD) 6 werden üblicherweise einer Schar bestehend aus einer Anzahl bis in den dreistelligen Bereich aus Vorräten entnommen und in die Längs- draht führungen 10 und weitere Elemente eingefädelt . In der dem Längsdrahtvorschub nachgeordneten Schweißmaschine werden taktweise Querdrähte ( QD) zugebracht , mit den Längsdrähten 6 verschweißt und bilden so die gewünschten Drahtgittermatten . Line wires 6 in the X-direction in a welding machine (not shown ) promoted . The longitudinal wires (LD) 6 are usually taken from a crowd consisting of a number up to the three-digit range from supplies and threaded into the longitudinal wire guides 10 and other elements. In the welding machine downstream of the line wire feed, transverse wires (QD) are fed in cycles, welded to the line wires 6 and thus form the desired wire mesh mats.

Durch den Vorschub der Längsdrähte 6 wird die vorbestimmte , oft variable Querdrahtteilung erzeugt . The advance of the longitudinal wires 6 produces the predetermined, often variable, transverse wire spacing.

Eine Garnitur einer Längsdraht führung 4 wird aus einer seitlichen Längsdraht führung 10 sowie zumindest einem unteren LD- Führungshebel 7 und einem oberen LD-Führungshebel 8 gebildet . Die Hebel bilden taktweise schließbare Zangen, die den LD in X-Richtung schieben . Der untere LD-Führungshebel 7 kann einstückig mit der seitlichen LD-Führung 10 ausgebildet sein . Die seitliche LD-Führung 10 ist zumindest ein Durchlass , ein Schlitz o . ä . für einen LD, der dessen Auslenkung in Y-Richtung verhindert . A set of a longitudinal wire guide 4 is formed from a lateral longitudinal wire guide 10 and at least one lower LD guide lever 7 and an upper LD guide lever 8 . The levers form intermittently closing tongs that push the LD in the X-direction. The lower LD guide lever 7 may be integrally formed with the LD side guide 10 . The LD side guide 10 is at least a passage , a slit o . uh . for an LD that prevents its deflection in the Y direction.

Die Längsdrahtschar wird in den einzelnen unteren und oberen LD-Führungshebel 7 , 8 mittels einer ( oder mehreren) Druckfedern 5 (wahlweise auch Hydraulik- , Pneumatik- , Elektrozylinder ) , dessen Federkraft in Richtung des Pfeiles F wirkt und die Hebel schließt , angepresst und gehalten . Das Öf fnen aller Längsdraht führungen 4 , d . h . die Klemmkraft-Deaktivierung erfolgt gemeinsam über zwei Anpressleisten 11 , die sich in Y- Richtung erstrecken und alle unteren und oberen LD-Führungshebel 7 , 8 betätigen . Diese Anpressleisten 11 werden vorzugsweise von einem oder mehreren Hydraulikzylindern ( Pneumatik- , Elektrozylinder ) betätigt . Für die exakte Längsdrahthöhe in Z-Richtung und Zusatz funktionen ist eine Höhenverstellung 12 vorzugsweise elektrisch vorgesehen . Die Längsdrahthöhe wird durch den Auflagepunkt eines Längsdrahtes 6 auf dem j eweiligen unteren LD-Führungshebel 7 bestimmt , welcher über einen LD-Führungshalter 9 mit der Höhenverstellung 12 verbunden ist . The longitudinal wire panel is pressed into the individual lower and upper LD guide levers 7, 8 by means of one (or more) compression springs 5 (optionally also hydraulic, pneumatic, electric cylinders), whose spring force acts in the direction of arrow F and closes the levers, and held . The opening of all longitudinal wire guides 4, d. H . the clamping force deactivation takes place jointly via two pressure strips 11 which extend in the Y direction and actuate all lower and upper LD guide levers 7 , 8 . These pressure strips 11 are preferably actuated by one or more hydraulic cylinders (pneumatic, electric cylinders). A height adjustment 12, preferably electrically, is provided for the exact longitudinal wire height in the Z direction and additional functions. The longitudinal wire height is determined by the support point of a longitudinal wire 6 on the respective lower LD guide lever 7 , which is connected to the height adjustment 12 via an LD guide holder 9 .

Die Garnituren von Längsdraht führungen 4 können entlang einer gemeinsamen Welle 13 in Y-Richtung verschoben werden, um die Abstände der LD 6 untereinander zu verändern und der Schweißmaschine zuzuführen . Alternativ können statt einer Welle 13 Schwalbenschwanz führungen, T-Nuten oder Äquivalentes verwendet werden . Dies kann für alle oder nur einzelne LD 6 erfolgen, und zwar in Zeitspannen des Stillstands , die während der kontinuierlichen Produktion und während die Schar der LD 6 gleichmäßig getaktet in X-Richtung vorgeschoben wird, vorkommen . The sets of longitudinal wire guides 4 can be moved along a common shaft 13 in the Y direction in order to change the distances between the LD 6 and feed them to the welding machine. Alternatively, dovetail guides, T-slots or equivalent can be used instead of a shaft 13. This can be done for all or only individual LD 6, specifically in periods of standstill that occur during continuous production and while the group of LD 6 is uniformly clocked advanced in the X direction.

Ändert sich der Durchmesser der verwendeten LD 6 und/oder der Querdrähte ( typische Durchmesser liegen zwischen 2 und 8 mm) , werden alle Längsdraht führungen 4 um den erforderlichen Di f ferenzbetrag in Z-Richtung angehoben oder abgesenkt . Dies kann erfindungsgemäß auch in der laufenden Produktion erfolgen, z . B . wenn sich der LD-Durchmesser von zwei direkt hintereinander herzustellenden Drahtgittermatten ändert . If the diameter of the LD 6 used and/or the transverse wires changes (typical diameters are between 2 and 8 mm), all longitudinal wire guides 4 are raised or lowered by the required difference in the Z direction. According to the invention, this can also be done during ongoing production, e.g. B. if the LD diameter of two wire mesh mats to be produced directly one behind the other changes.

Die taktbare Längsdraht führung 4 kombiniert daher in vortei lhafter Weise die Funktionen der allgemeinen Längsdraht Zuführung, der Längsdraht führung hinsichtlich der Binnenabstände und der Längsdrahtpositionierung hinsichtlich des Höhenniveaus einlaufseitig an automatisierten Schweißmaschinen . Die Längsdrahtdurchmesser sind variabel , da sich eine Schweißmaschine mit erfindungsgemäßer Längsdraht führung 4 konstruktionsbedingt automatisiert umstellen kann . Eine Umstellung der Längsdrahtteilung erfolgt zwar nicht automatisiert , gestaltet sich j edoch auch denkbar einfach gemäß der hier dargelegten Form . The tactable line wire guide 4 therefore advantageously combines the functions of the general line wire feed, the line wire guide with regard to the internal distances and the line wire positioning with regard to the height level on the inlet side of automated welding machines. The line wire diameters are variable, since a welding machine with a line wire guide 4 according to the invention can be automatically adjusted due to the design. A conversion of the longitudinal wire pitch is not automated, but it is also very simple in the form presented here.

Die Längsstabschar kann in Y-Richtung stufenlos aufgenommen werden . Die Längsstabschar kann nach erfolgter Aufnahme mit in Y-Richtung änderbaren Abständen geführt werden, da die Längs- drahtführung 4 mit separat wirkender Klemmkraftaufbringung sowie mit stufenloser, in über die gesamte Mattenbreite wirkender Klemmkraft-Deaktivierung ausgestattet ist . Die Klemmkraftaufbringung mittels oberer und unterer LD-Führungshebel 7 , 8 ist material- und oberflächenschonend . The longitudinal bar panel can be picked up steplessly in the Y-direction. After being picked up, the group of longitudinal bars can be guided with variable distances in the Y-direction, since the longitudinal wire guide 4 is equipped with separately acting clamping force application as well as stepless clamping force deactivation acting over the entire width of the mat. The application of the clamping force by means of the upper and lower LD guide levers 7, 8 is gentle on the material and the surface.

Bei Bedarf kann die Längsstabschar in X-Richtung auch zurücktransportiert werden . Dies ist in der Steuerung programmiert , bedarf an der Vorrichtung aber keiner Modi fikationen . Die Längsstabschar kann weiters in X-Richtung an den Schweißelektroden ausgerichtet werden; sie kann sogar bis zum Schweißpunkt gebracht werden, ohne die Klemmung zu verlieren . Dadurch ist eine sicherere Zubringung ermöglicht . If necessary, the longitudinal bar panel can also be transported back in the X direction. This is programmed in the controller but does not require any modifications to the device. The group of longitudinal bars can also be aligned in the X-direction on the welding electrodes; it can even be brought up to the welding spot without losing the clamp. This enables safer delivery.

In Z-Richtung kann die LD-Schar zudem zum Querdraht-Durchmesserausgleich angehoben werden, falls sich der Durchmesser der Querdrähte ändern sollte . Ein Ausgleich in Z-Richtung ist im Detail auch aus einer Reihe weiterer Faktoren erzielbar, die die Variabilität der Maschine und die Qualität der geschweißten Matten betri f ft , z . B . wenn die Einschweißtief e an der Längsstabschar programmgesteuert vorbestimmt und ausgegl ichen werden soll , wenn ein all fällig auftretender Elektroden- verschleiß aus zugleichen ist , wenn Querdrähte unterhalb der Mattenebene verschweißt werden sollen, oder auch wenn Gitterebenheit in Längsrichtung beeinflusst werden soll . Im Stand der Technik ist dies nicht möglich . In the Z direction, the LD panel can also be raised to compensate for cross wire diameters if the diameter of the cross wires should change. A balance in the Z-direction can also be achieved from a number of other factors that affect the variability of the machine and the quality of the welded mesh, e.g. B. if the welding depth on the longitudinal bar array is to be predetermined and compensated for by program control, if any electrode wear that may occur wear out at the same time is when cross wires are to be welded below the mesh level, or when the evenness of the mesh is to be influenced in the longitudinal direction. This is not possible in the prior art.

Die Längsdraht führung 4 kann zum Zwecke eines überstandslosen Schweißens die Längsstabschar stirnseitig in X-Richtung weitere Längsdrähte 6 nachschieben . Schließlich können auch Führungseinheiten den Gitterverband von Querdrahthaltemagneten (nicht gezeigt ) lösen . The longitudinal wire guide 4 can push further longitudinal wires 6 along the face of the family of longitudinal rods in the X-direction for the purpose of welding without overlap. Finally, guide units can also detach the lattice structure of transverse wire holding magnets (not shown).
