Abstract

Described is a method of producing wire-mesh mats (G) from criss-cross longitudinal (L) and transverse (Q) wires welded together at the crossing points. The longitudinal wires (L) are drawn continuously from a feed into a buffer store (4) from where they are fed further. The longitudinal wires (L) in front of the welding line (X-X) in the welding machine (7) are clamped at their front ends to additional longitudinal wires (L) drawn from the feed through the buffer store (4) and brought into position. All the longitudinal wires (L) are then displaced horizontally, in front of the welding line (X-X), at right angles to their longitudinal axis to give a predetermined spacing, and predetermined longitudinal wires (L) are fed, together with transverse wires (Q), on a cyclic basis, to the welding line and a selectable length cut off from the wire feed. The welded mat (G) is pulled out of the welding machine on a cyclic basis at the same time as the longitudinal wires are fed in and finally stacked.

Description

Verfahren und Anlage zum Herstellen von Gittermatten Process and plant for the production of mesh mats
Die Erfindung betrifft ein Verfahren und eine Anlage zum Herstellen von Gittermatten aus einander kreuzenden und an den Kreuzungspunkten miteinander verschweißten Längs- und Querdräh¬ ten.The invention relates to a method and a system for producing lattice mats from longitudinal and transverse wires that cross each other and are welded together at the crossing points.
Aus der DE-Al-3744768 ist ein Verfahren zur Herstellung von Betonstahlmatten bekannt, bei dem die Längsdrähte mittels einzeln ansteuerbarer Vorschubelemente direkt von Spulen abge- zogen und von individuell ansteuerbaren, nachgeschalteten Schneideinrichtungen vom Materialstrang vor der Schweißlinie in beliebiger Länge abgeschnitten werden. Alle Längsdrähte liegen an den Schneidkanten der Schneideinrichtung an und werden von den Vorschubelementen geklemmt. Nachteilig ist bei dieser Ar- beitsweise, daß eine stufenlose Einstellung der Längsdrahttei¬ lung nicht möglich ist und ein Abzug der Längsdrähte direkt von den Spulen erfolgt.From DE-Al-3744768 a method for the production of reinforcing steel mats is known, in which the longitudinal wires are pulled directly from coils by means of individually controllable feed elements and are cut from the material strand in front of the welding line in any length by individually controllable, downstream cutting devices. All longitudinal wires lie on the cutting edges of the cutting device and are clamped by the feed elements. A disadvantage of this method of operation is that a continuous adjustment of the line wire division is not possible and that the line wires are drawn off directly from the coils.
Aus der DE-Cl-3530384 ist eine Schweißmaschine bekannt, die eine sich über ihre gesamte Breite erstreckende, angetrie- bene Walze aufweist, und deren Schweißeinheiten einlaufseitig eine zustellbare, mit der Walze zusammenwirkende Klemmrolle so¬ wie eine zwischen der Klemmrolle und den Schweißelektroden an¬ geordnete Längsdrahtschere aufweisen. Die Schweißeinheiten samt Klemmrolle und Längsdrahtschere sind zum Einstellen unter- schiedlicher Längsdrahtteilungen auf Schienen quer zur Produk¬ tionsrichtung einzeln verfahrbar. Diese Konstruktion hat den Nachteil, daß die Längsdrähte erst nach dem Positionieren der Schweißeinheiten in die aus Walze und zugehöriger Klemmrolle bestehenden Vorschubvorrichtung eingefädelt werden können. Aus der DE-Al-4137122 ist ein Verfahren zum kontinuierli¬ chen Fertigen von Betonstahlmatten bekannt, bei dem der Längs¬ oder Querdraht mittels Rollen von der Spule abgezogen und in zumindest eine als Pufferspeicher dienende Ringschlaufe einge¬ schoben wird. Aufgabe der Erfindung ist es, die geschilderten Nachteile zu vermeiden und ein Verfahren sowie eine Anlage der einleitend angegebenen Art zu schaffen, welche das laute, lärmintensive Durchtrennen der Gittermatten vermeiden, eine kontinuierliche Produktion der Gittermatten durch eine rasche Bereitstellung der erforderlichen Langsdrahte sowie eine rasche und einfache Änderung der Längsdrahtteilung und Langsdrahtstarken ermögli¬ chen. Das erfindungsgemaße Verfahren zeichnet sich dadurch aus, daß die Langsdrahte von einem Drahtvorrat kontinuierlich in ei¬ nen Pufferspeicher abgezogen und aus diesem vorgeschoben wer¬ den, worauf die Langsdrahte vor der Schweißlinie einer Gitter- schweißmaschine gemeinsam mit weiteren, über den Pufferspeicher vom Drahtvorrat abgezogenen, in Bereitstellung gebrachten Langsdrahten mit ihren vorderen Enden geklemmt werden, sodann alle Langsdrahte vor der Schweißlinie in horizontaler Richtung quer zu ihrer Langsachse auf eine vorbestimmte Längsdrahttei¬ lung verschoben und vorbestimmte Langsdrahte gemeinsam mit Querdrahten der Schweißlinie taktweise zugeführt und vor der Schweißlinie in wahlbarer Lange vom Drahtvorrat abgetrennt wer¬ den, und daß die fertige Gittermatte synchron mit dem Langs- drahtvorschub taktweise aus der Gitterschweißmaschine ausgezo¬ gen und anschließend gestapelt wird.From DE-Cl-3530384 a welding machine is known which has a driven roller which extends over its entire width and the welding units of which on the inlet side have an adjustable clamping roller which interacts with the roller and one between the clamping roller and the welding electrodes ¬ have ordered line wire cutters. The welding units, including the clamping roller and line wire shears, can be moved individually to set different line wire divisions on rails transversely to the direction of production. This construction has the disadvantage that the longitudinal wires can only be threaded into the feed device consisting of roller and associated clamping roller after the welding units have been positioned. From DE-Al-4137122 a method for the continuous manufacture of reinforcing steel meshes is known, in which the line or cross wire is pulled off the spool by means of rollers and inserted into at least one ring loop serving as a buffer store. The object of the invention is to avoid the disadvantages described and to provide a method and a system of the type specified in the introduction, which avoid the loud, noisy cutting of the grid mats, a continuous Production of the lattice mats by rapid provision of the required long wires as well as a quick and easy change in the longitudinal wire division and long wire strengths. The method according to the invention is characterized in that the longitudinal wires are continuously drawn from a wire supply into a buffer store and are advanced therefrom, whereupon the longitudinal wires in front of the welding line of a grid welding machine, together with further ones, are drawn off from the wire supply via the buffer store. provided longitudinal wires are clamped with their front ends, then all longitudinal wires in front of the welding line are displaced in the horizontal direction transversely to their longitudinal axis to a predetermined longitudinal wire division and predetermined longitudinal wires are fed together with transverse wires to the welding line in cycles and in front of the welding line in a selectable length from the wire supply are separated, and that the finished mesh mat is pulled out of the mesh welding machine in cycles and then stacked in synchronism with the longitudinal wire feed.
Durch das erfindungsgemaße Verfahren kann das konventio- nelle Durchtrennen der fertiggeschweißten Gittermatten hinter der Gitterschweißmaschine entfallen, das mit einer starken, ge- sundheitsgefardenden Larmentwicklung verbunden ist.The method according to the invention makes it possible to dispense with the conventional cutting of the finished welded mesh mats behind the mesh welding machine, which is associated with a strong, health-threatening development of larvae.

Die Langsdraht-Ablaufvorrichtung 1 weist je Langsdraht L, LI, L2 je em Spulengestell 13 und eme Spule 14 auf. Die An¬ zahl der Spulengestelle 13 entspricht zumindest der Anzahl der Langsdrahte in der herzustellenden Gittermatte, ist im Rahmen der Erfindung vorzugsweise jedoch großer als diese, um für Pro¬ grammwechsel bei der Gittermattenherstellung oder bei Störungen im Langsdrahtablauf genügend Langsdrahte m Bereitstellung zu haben. Die horizontale Richtvorrichtung 2 besteht je Langsdraht aus jeweils zwei hintereinander angeordneten, horizontalen Dressurvorrichtungen 15, die je mehrere zueinander versetzt an¬ geordnete Richtrollen 16 aufweisen, wobei die Achsen der Richt- rollen 16 vertikal verlaufen und die Langsdrahte L, LI, L2 da¬ durch in der horizontalen Ebene gerade gerichtet werden.The system shown in FIGS. 1 and 2 is used to manufacture lattice mats G from longitudinal wires L, LI, L2 and transverse wires Q which cross each other and are welded to one another at the crossing points.

Der Langsdrahtspeicher 4 besteht im wesentlichen aus einem Rahmengestell 19, das derart ausgebildet ist, daß für jeden Längsdraht L, LI, L2 eine separate Schlaufenführungsbahn defi¬ niert wird, in welcher der Langsdraht in Form von Ringschlaufen S geführt wird. Die Längsdrahtschlaufen S sind in ihrer Größe veränderlich, um das kontinuierliche Abziehen der Langsdrahte von den Längsdrahtspulen 14 mit dem taktweisen Einschieben der Längsdrähte in die Gitterschweißmaschine 7 zu koordinieren.The long wire storage 4 essentially consists of a frame 19 which is designed such that a separate loop guideway is defined for each longitudinal wire L, LI, L2, in which the long wire is guided in the form of ring loops S.

Im Rahmen der Erfindung ist es je¬ doch auch möglich, nur eme Schneidvorrichtung 22 vorzusehen, wobei diese zum Abtrennen der Langsdrahte unabhängig von den Prazisionsrollenvorschuben 21 entsprechend dem Doppelpfeil P3 quer zur Langsachse der Langsdrahte verschiebbar ist.The vertical straightening device 5 arranged downstream of the long wire store 4 consists of a vertical dressage 20 per long wire, which has a plurality of straightening rolls arranged offset from one another, the axes of these straightening rolls running horizontally, so that the long wires are now also straightened exactly in the vertical plane . The cutting and feed device 6 has, for each longitudinal wire, a precision roller feed 21, which consists of a driven feed roller and a counter roller, for inserting the respective longitudinal wire into the grid welding machine 7 and a cutting device 22 for cutting through the long wire, each precision roller feed 21 with the associated one Cutting device 22 is coupled. To position the longitudinal wires according to the desired longitudinal wire division in the lattice mat G to be manufactured, clamp the precision roller 21 feeds the long wires and tightly smd corresponding to the D ouble arrow P3 displaceable perpendicularly to the direction of production in Pl horizon ¬ ta l he direction. Within the scope of the invention, however, it is also possible to provide only one cutting device 22, which can be displaced transversely to the longitudinal axis of the longitudinal wires in accordance with the double arrow P3 in order to cut off the longitudinal wires independently of the precision roller feeds 21.
Die Gitterschweißmaschine 7 arbeitet nach der Widerstands¬ schweißmethode und besteht im wesentlichen aus emer Reihe von mehreren Schweißkopfen 23, die in einem Gestell 24 entlang ei¬ ner horizontalen, senkrecht zur Produktionsrichtung Pl verlau¬ fenden Schweißlinie X-X angeordnet sind und zum Verschweißen der Kreuzungspunkte der Querdrahte mit der Längsdrahtschar die¬ nen. Jeder Schweißkopf 23 besteht aus einer Unterelektrode und aus einer Oberelektrode, die unterhalb bzw. oberhalb der Ebene der Längsdrahtschar angeordnet smd und entweder einzeln oder gemeinsam zueinander anstellbar und mit dem erforderlichen Schweißdruck beaufschlagbar smd. Zum Verandern der Längsdraht¬ teilung in der herzustellenden Gittermatte G sind die Schweiß- köpfe 23 relativ zueinander einstellbar. An der Emlaufseite der Gitterschweißmaschine 7 ist für jeden Langsdraht eme Langsdrahtfuhrung 25 angeordnet. Die Gitterschweißmaschine 7 kann nach dem Einzelpunkt- oder dem Doppelpunktschweißverfahren arbeiten. Die Transport- und Stapelvorrichtung 9 hat einen auf Stut¬ zen 26 angeordneten Tragrahmen 27, der zwei Langstrager 28 auf¬ weist. Auf jedem Langstrager 28 ist jeweils eine Fahrbahnschie¬ ne 29 angeordnet, auf der em angetriebener Transportwagen 30 entsprechend dem Doppelpfeil P4 verschiebbar ist. Der Trans- portwagen 30 ist mit einer Vorrichtung zum Greifen der aus der Gitterschweißmaschine 7 auszuziehenden Gittermatten G versehen, wobei die Greifvorrichtung an zumindest einem Querdraht an zu¬ mindest zwei Stellen angreift, um em präzises, schlupffreies und paralleles Fordern der Gittermatte G zu gewährleisten. Zur Abstutzung der Gittermatten G beim Fordern derselben sind in der Transport- und Stapelvorrichtung 8 zumindest zwei Stutzrol¬ len 31 vorgesehen, die miteinander gekoppelt auf an dem Trag¬ rahmen 27 angeordneten Laufbahnschienen 32 entsprechend dem Doppelpfeil P5 ausemanderziehbar smd. Die fertigen Gittermat¬ ten G werden auf einem hohenverstellbaren Hubtisch 33 abgelegt, der mit einem Rollgang 34 zum leichteren Abtransport des kom¬ pletten Gittermattenstapels M versehen ist. Die Ablaufvorrichtung 9 für den Querdraht besteht aus ei¬ nem Spulengestell 35, das eine in einem Drehzapfen 36 gelagerte Spule 37 in Arbeltsstellung und eme in einem Drehzapfen 36' gelagerte Spule 37' m Warteposition tragt. Um einen einwand¬ freien Ablauf des Querdrahtes Q zu gewährleisten, werden die Spulen 37, 37' mittels Bremsen 38 bzw. 38' abgebremst. Zum Ein¬ fädeln des Querdrahtes in den Querdrahtspeicher 11 und zum Auf- und Abwickeln etwaiger Restlangen auf den Spulen 37, 37' bei Produktionsende bzw. Drahtstarkenwechsel ist die Querdraht-Ab- laufvorrichtung 9 mit einem Hilfsantrieb 39 versehen. Die Querdraht-Vorschubvorrichtung 10 besteht aus einer an¬ getriebenen Vorschubrolle und einer angefederten Gegenrolle.The grid welding machine 7 works according to the resistance welding method and essentially consists of a series of several welding heads 23, which are arranged in a frame 24 along a horizontal welding line XX running perpendicular to the production direction P1 and for welding the crossing points of the transverse wires with the longitudinal wire coulters. Each welding head 23 consists of a lower electrode and an upper electrode, which are arranged below or above the plane of the longitudinal wire array and can be adjusted either individually or together and can be subjected to the required welding pressure. The welding heads 23 can be adjusted relative to one another in order to change the longitudinal wire division in the lattice mat G to be produced. A long wire guide 25 is arranged on the upstream side of the grid welding machine 7 for each long wire. The grid welding machine 7 can work according to the single-point or the double-spot welding method. The transport and stacking device 9 has a support frame 27 which is arranged on supports 26 and has two long beams 28. A carriageway rail 29 is arranged on each long beam 28, on which a driven transport carriage 30 can be moved in accordance with the double arrow P4. The transport carriage 30 is provided with a device for gripping the grid mats G to be pulled out of the grid welding machine 7, the gripping device acting on at least one cross wire at at least two points in order to ensure precise, slip-free and parallel loading of the grid mat G. To support the lattice mats G when they are being conveyed, at least two support rollers 31 are provided in the transport and stacking device 8, which are coupled to one another on track rails 32 arranged on the support frame 27 in accordance with the Double arrow P5 expandable smd. The finished lattice mats G are placed on a height-adjustable lifting table 33, which is provided with a roller table 34 for easier removal of the entire lattice mat stack M. The run-off device 9 for the cross wire consists of a bobbin frame 35 which bears a bobbin 37 mounted in a pivot 36 in the working position and a bobbin 37 'mounted in a pivot 36' in the waiting position. In order to ensure that the cross wire Q runs properly, the coils 37, 37 'are braked by means of brakes 38 and 38', respectively. For threading the cross wire into the cross wire storage 11 and for winding and unwinding any remaining lengths on the bobbins 37, 37 'at the end of production or changing the wire gauge, the cross wire drain device 9 is provided with an auxiliary drive 39. The cross-wire feed device 10 consists of a driven feed roller and a spring-loaded counter roller.
Die beschriebene Anlage arbeitet in folgender Weise: Die Langsdrahte werden mit Hilfe des Rollenvorschubs 17 der Richt- und Vorschubvorrichtung 3 kontinuierlich von den Spulen 14 der Ablaufvorrichtung 1 abgezogen, in der horizontalen Dressur 15 der horizontalen Richtvorrichtung 2 in der horizontalen Ebene gerade gerichtet und erhalten mit Hilfe der Tendenzdressur 18 der Rieht- und Vorschubvorrichtung 3 die zum einwandfreien Ab¬ lauf der Langsdrahte im Langsdrahtspeicher 4 erforderliche Ge- stalt einer Drahtschlaufe S. Die dem Langsdrahtspeicher 4 nach¬ geschaltete vertikale Dressur 20 der vertikalen Richtvorrich¬ tung 5 korrigiert die Längsdrahtschlaufen wieder und richtet die Langsdrahte in vertikaler Richtung gerade.The system described works in the following manner: The longitudinal wires are continuously drawn off from the coils 14 of the discharge device 1 with the aid of the roller feed 17 of the straightening and feeding device 3, straightened in the horizontal dressing 15 of the horizontal straightening device 2 in the horizontal plane and are retained With the help of the tendency dressing 18 of the straightening and feeding device 3, the shape of a wire loop S required for the smooth running of the long wires in the long wire store 4 is corrected. The vertical dressing 20 of the vertical straightening device 5 downstream of the long wire store 4 corrects the longitudinal wire loops again and again straightens the long wires in the vertical direction.
Durch den Prazisionsrollenvorschub 21 der Schneid- und Vorschubvorrichtung 6 werden die zum Herstellen der Gittermatte G benotigten Langsdrahte in die Gitterschweißmaschine 7 takt¬ weise eingeschoben und dort mittels der Schweißkopfe 23 mit den zugefuhrten Querdrahten Q verschweißt. Die nicht benotigten, sich in Bereitstellung befindlichen Langsdrahte werden von lh- ren zugehörigen Prazisionsrollenvorschuben 21 festgeklemmt.Due to the precision roller feed 21 of the cutting and feed device 6, the long wires required for producing the grid mat G are inserted into the grid welding machine 7 in cycles and are welded there with the supplied transverse wires Q by means of the welding heads 23. The long wires which are not required and which are in preparation are clamped by their associated precision roller feeds 21.
Die aus der Gitterschweißmaschme 7 austretenden Gitter¬ matten G werden von der Greifvorrichtung des Transportwagens 30 der Transport- und Stapelvorrichtung 8 erfaßt und entsprechend der Produktionsrichtung Pl synchron und im Takt mit dem durch die Präzisionsrollenvorschübe 21 erfolgenden Vorschub der Längsdrähte aus der Gitterschweißmaschine 7 herausgezogen. Hierbei werden die Gittermatten G von den Stützrollen 31 unter- stützt, die je nach Länge der Gittermatten mehr oder weniger auseinandergezogen werden. Nach dem Abtrennen der Längsdrähte vom Drahtvorrat durch die Schneidvorrichtung 22 wird die Git¬ termatte G in der Gitterschweißmaschine 7 fertig geschweißt, wobei der Vorschub der Gittermatte G durch den Transportwagen 30 im Takt der Gitterschweißmaschine 7 erfolgt. Nach Fertig¬ stellung der Gittermatte G wird diese rasch und kontinuierlich aus der Gitterschweißmaschine 7 herausgezogen und anschließend auf dem Hubtisch 33 abgelegt, wobei zum Ablegen der Gittermatte G die Stützrollen 31 in ihre Ausgangslage an der Einlaufseite der Transport- und Stapelvorrichtung 8 zurückgefahren werden und die Greifvorrichtung des Transportwagens 30 von der Gitter¬ matte G gelöst wird.The lattice mats G emerging from the lattice welding machine 7 are gripped by the gripping device of the transport carriage 30 of the transport and stacking device 8 and correspondingly the production direction Pl is pulled out of the grid welding machine 7 synchronously and in time with the feed of the longitudinal wires by the precision roller feeds 21. The lattice mats G are supported by the support rollers 31, which are pulled apart more or less depending on the length of the lattice mats. After the longitudinal wires have been separated from the wire supply by the cutting device 22, the grid mat G is finished welded in the grid welding machine 7, the grid mat G being fed by the transport carriage 30 in time with the grid welding machine 7. After completion of the lattice mat G, it is quickly and continuously pulled out of the lattice welding machine 7 and then placed on the lifting table 33, the support rollers 31 being moved back to their starting position on the inlet side of the transport and stacking device 8 for depositing the lattice mat G, and the Gripping device of the transport carriage 30 is released from the grid mat G.
Weitere Gittermatten können unmittelbar anschließend her¬ gestellt werden, indem erneut Längsdrähte der Gitterschweißma- schine 7 zugeführt werden. Im Rahmen der Erfindung ist es hier¬ bei möglich, die Längsdrähte entweder jeweils von denselben Spulen abzuziehen, die auch die vorher hergestellte Gittermatte mit Längsdrähten versorgt haben, oder die Längsdrähte teilweise oder zur Gänze von neuen in Bereitstellung befindlichen Spulen abzuziehen. Hierbei werden, falls erforderlich, die Präzisions¬ rollenvorschübe 21 gegebenenfalls zusammen mit den gekoppelten Schneidvorrichtungen 22 entsprechend der gewünschten Längsdr¬ ahtteilung durch Verschiebung in horizontaler Richtung entspre¬ chend dem Doppelpfeil P3 neu positioniert. Durch diese Vor- gangsweise können ohne Produktionsunterbrechung und ohne Ver¬ schweißen der Längsdrähte leere Spulen schnell ersetzt werden sowie in einfacher Weise die Längsdrahtteilung sowie die Durch¬ messer der Längsdrähte der herzustellenden Gittermatten verän¬ dert werden. Zum Verändern der Längsdrahtteilung in der herzustellenden Gittermatte G können im Rahmen der Erfindung die zugehörigen Präzisionsrollenvorschübe 21, gegebenenfalls mit den zugehöri¬ gen Schneidvorrichtungen 22, mit den Schweißköpfen 23 der Git- terschweißmaschine 7 derart gekoppelt werden, daß sie gemeinsam relativ zueinander einstellbar sind.Further lattice mats can be produced immediately afterwards by again feeding longitudinal wires to the lattice welding machine 7. In the context of the invention, it is possible in this case to either pull the longitudinal wires from the same coils that have supplied the previously produced grid mat with longitudinal wires, or to pull the longitudinal wires partially or entirely from new coils in preparation. In this case, if necessary, the precision roller feeds 21, if necessary together with the coupled cutting devices 22, are repositioned in accordance with the desired longitudinal wire division by displacement in the horizontal direction in accordance with the double arrow P3. With this procedure, empty coils can be quickly replaced without interrupting production and without welding the longitudinal wires, and the longitudinal wire division and the diameter of the longitudinal wires of the lattice mats to be produced can be changed in a simple manner. In order to change the longitudinal wire division in the lattice mat G to be produced, the associated precision roller feeds 21, optionally with the associated cutting devices 22, with the welding heads 23 of the lattice gates Terschweißmaschine 7 are coupled such that they are jointly adjustable relative to each other.
Die Schneidvorrichtungen 22 ermöglichen außerdem ein Ab¬ trennen einzelner Langsdrahte wahrend dem Schweißen der Gitter- matte G, so daß es möglich ist, individuelle gestaltete Gitter¬ matten mit unterschiedlich langen Langsdrahten innerhalb einer Gittermatte und auch Gittermatten mit Unterbrechungen in den Langsdrahten herzustellen.The cutting devices 22 also make it possible to separate individual longitudinal wires during the welding of the grid mat G, so that it is possible to produce individually designed grid mats with different lengths of longitudinal wire within a grid mat and also grid mats with interruptions in the longitudinal wires.
Zum Zufuhren des Querdrahtes ist zunächst eme Quer- drahtspule 37 m Arbeltsstellung, wahrend eine weitere Quer¬ drahtspule 37' sich in Wartestellung befindet. Der Quer- drahtspeicher 11 weist, im Prinzip ähnlich dem Langsdrahtspei¬ cher 4, eme in ihrer Große kontrolliert veränderliche Ring¬ schlaufe auf, um den kontinuierlichen Abzug des Querdrahtes Q von der Spule 37 bzw. 37' mit dem taktweisen Einschießen des Querdrahtes in die Emschußlmie E der Gitterschweißmaschine 7 zu koordinieren. Aus der Emschußlmie E wird der Querdraht durch geeignete Hilfsmittel in die Schweißlinie X-X der Gitter¬ schweißmaschine 7 befordert. Im Rahmen der Erfindung ist jedoch auch möglich den Querdraht Q direkt in die Schweißlinie X-X einzuschießen.To feed the cross wire, a cross wire coil 37 m is first in the working position, while a further cross wire coil 37 'is in the waiting position. The cross-wire storage 11 has, in principle similar to the long-wire storage 4, a ring loop of variable size that can be controlled in order to continuously withdraw the cross-wire Q from the coil 37 or 37 'with the intermittent shooting of the cross-wire into the Coordinate Emschußlmie E of the grid welding machine 7. The cross wire is conveyed from the discharge E into the welding line X-X of the grid welding machine 7 by suitable aids. In the context of the invention, however, it is also possible to shoot the cross wire Q directly into the welding line X-X.
Es versteht sich, daß das dargestellte Ausfuhrungsbeispiel im Rahmen des allgemeinen Erfindungsgedankens verschiedentlich, insbesondere hinsichtlich der Anordnung der Emschußlmie E des Querdrahtes, abgewandelt werden kann. Die Emschußlmie E kann unterhalb und/oder oberhalb der Ebene der Längsdrahtschar und in Produktionsrichtung Pl gesehen sowohl vor als auch hinter der Schweißlinie X-X verlaufen. Die Zufuhr des Querdrahtes kann im Rahmen der Erfindung sowohl von einer Seite der Gitter- schweißmaschine 7 als auch von beiden Seiten entlang der Em¬ schußlmie E erfolgen. In die Emschußlmie E können im Rahmen der Erfindung auch zwei Querdrahte, als sogenannte Doppel¬ drahte, eingeführt werden.It goes without saying that the exemplary embodiment shown can be modified in various ways within the scope of the general inventive concept, in particular with regard to the arrangement of the emissivity E of the transverse wire. Emschußlmie E can run below and / or above the plane of the longitudinal wire coulter and in the direction of production Pl both in front of and behind the welding line X-X. In the context of the invention, the cross wire can be fed in from one side of the grid welding machine 7 as well as from both sides along the path E. Within the scope of the invention, two transverse wires, so-called double wires, can also be introduced into the discharge E.
Des weiteren ist es im Rahmen der Erfindung möglich, be- reits abgelangte, gerade gerichtete Querdrahte einzeln oder zu zweit, als sogenannter Doppeldraht, aus einem unterhalb und/oder oberhalb der Ebene der Längsdrahtschar angeordnetem Magazin senkrecht zur Emschußlmie E der Gitterschweißmaschine 7 zuzuführen oder auch direkt in die Schweißlinie X-X der Git¬ terschweißmaschine 7 zu befordern.Furthermore, it is possible within the scope of the invention to cut straight straight wires, either straight or in pairs, as so-called double wires, from a magazine arranged below and / or above the plane of the longitudinal wire array perpendicular to the emission E of the lattice welding machine 7 or to request it directly into the welding line XX of the grid welding machine 7.
Ferner ist es im Rahmen der Erfindung möglich, zur Erhö¬ hung der Produktionsgeschwmdigkeit zwei Emschußlmie E und zwei Schweißlmien X-X vorzusehen, so daß die Gitterschweißma¬ schine 7 im in Langsdrahtrichtung arbeitendem Doppelpunkt¬ schweißverfahren arbeiten kann. Furthermore, it is possible within the scope of the invention to provide two discharge lines E and two welding lines X-X in order to increase the production speed, so that the grid welding machine 7 can operate in the double-spot welding process operating in the longitudinal wire direction.
