Description

Die Erfindung betrifft eine Vorrichtung zum Beschicken einer Gitterschweißmaschine mit Längselementen, mit in einer Vorschubebene quer zur Vorschubrichtung mit konstantem gegenseitigem Abstand angeordneten Organen zum Einführen der Längselemente in in der Vorschubebene quer zur Vorschubrichtung verschwenkbare Zuführkanäle.The invention relates to a device for loading a grid welding machine with longitudinal elements, with organs arranged in a feed plane transverse to the feed direction with constant mutual spacing for introducing the longitudinal elements into feed channels pivotable in the feed plane transverse to the feed direction.

Aus der AT-PS 348.314 ist eine Vorrichtung zum Zuführen einer Schar von zueinander parallelen, hochkant stehenden Flacheisenbändern zu einer Gitterrost-Schweißmaschine bekannt. Um den Abstand der Bänder in der Schweißmaschine frei wählen zu können, wird zwischen einem hinsichtlich des gegenseitigen Abstandes unveränderbaren Satz von Führungsrohren und der Schweißmaschine ein Satz von Verteilerrohren zwischengeschaltet, deren einlaufseitige Enden in festem, dem Abstand der Führungsrohre entsprechendem-Abstand voneinander angeordnet sind und die schwenkbar gelagert sind, so daß der gegenseitige Abstand ihrer auslaufseitigen Enden wählbar ist, wobei diese Rohre in der gewählten Lage fixierbar sind. Bei der bekannten Vorrichtung definieren die Verteilerrohre Zuführkanäle mit fest vorgegebenen, unveränderlichen Breiten und sind nur je als gesamte Einheit verschwenkbar. Bedingt durch diese Ausführung ist der Schwenkbereich jedes Verteilerrohres jeweils durch den Schwenkbereich des benachbarten Verteilerrohres begrenzt. Außerdem wird durch die konstante Breite der Verteilerrohre eine konstante untere Grenze für den Abstand der Längselemente zueinander vorgegeben.From AT-PS 348.314 a device for feeding a family of parallel, upright standing flat iron strips to a grating welding machine is known. In order to be able to freely select the spacing of the belts in the welding machine, a set of distributor pipes is interposed between a set of guide tubes which cannot be changed with respect to the mutual spacing, the inlet-side ends of which are arranged at a fixed distance from one another corresponding to the spacing of the guide tubes and which are pivotally mounted so that the mutual distance between their outlet ends can be selected, these tubes being fixable in the selected position. In the known device, the distributor pipes define feed channels with fixed, unchangeable widths and can only be pivoted as a whole unit. Due to this design, the swivel range of each distributor pipe is limited by the swivel range of the adjacent distributor pipe. In addition, a constant lower limit for the spacing of the longitudinal elements from one another is predetermined by the constant width of the distributor pipes.

Die Erfindung zielt darauf ab, eine Beschickungsvorrichtung zu schaffen, bei der mit Hilfe variabler Zuführkanäle sowohl die Anzahl als auch der gegenseitige Abstand der Längselemente frei wählbar sind. Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, daß jeder Zuführkanal seitlich durch mit dem Einführorgan fest verbundene, einzeln quer zur Vorschubrichtung verschwenkbare Führungselemente begrenzt ist, deren freie Enden an der Einlaufseite von nachgeschalteten Zuführorganen der Schweißmaschine mittels an diesen Zuführorganen befestigten Leiteinrichtungen lösbar festlegbar sind, wobei die quer zur Vorschubrichtung verschiebbaren Zuführorgane auf frei wählbare Querabstände einstellbar sind und wobei jedes Zuführorgan über die Führungselemente mit einem oder mehreren Zuführkanälen verbindbar ist.The invention aims to provide a loading device in which both the number and the mutual spacing of the longitudinal elements can be freely selected with the aid of variable feed channels. The device according to the invention is characterized in that each feed channel is laterally delimited by guide elements which are firmly connected to the insertion member and can be pivoted individually transversely to the feed direction, the free ends of which on the inlet side of downstream feed elements of the welding machine can be detachably fixed by means of guide devices attached to these feed elements, the feed elements which can be displaced transversely to the feed direction being adjustable to freely selectable transverse distances, and each feed element being connectable to one or more feed channels via the guide elements.

Es sei erwähnt, daß es aus der AT-PS 228.028 bei einer Vorrichtung anderer Art bekannt ist, die Zuführorgane quer zur Vorschubrichtung zu verschieben.It should be mentioned that it is known from AT-PS 228.028 in a device of a different type to move the feed members transversely to the feed direction.

Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung sind die durch Trichter gebildeten Einführorgane mit ihren Führungselementen auf einer Achse in Richtung senkrecht zur Vorschubebene der Längselemente verschwenkbar montiert.According to a preferred embodiment of the invention, the insertion members formed by funnels are pivotally mounted with their guide elements on an axis in the direction perpendicular to the feed plane of the longitudinal elements.

Vorzugsweise bestehen die Führungselemente aus verschleißfesten Federstahlbändern. Nach einem weiteren Erfindungsmerkmal sind die Leiteinrichtungen durch senkrecht zur Vorschubebene der Längselemente verschwenkbare Verschlußklappen gebildet.The guide elements preferably consist of wear-resistant spring steel strips. According to a further feature of the invention, the guide devices are formed by closure flaps which can be pivoted perpendicularly to the feed plane of the longitudinal elements.

Eine Weiterbildung der Erfindung zeichnet sich dadurch aus, daß die Zuführorgane durch einen um eine quer zur Vorschubrichtung verlaufende Achse drehbaren Teilungsrevolver, der an seinem Umfang verteilt Führungsnuten enthält, abstützbar und in diesen Führungsnuten fixierbar sind, wobei eine der Führungsnuten beliebig wählbare Abstände der Zuführorgane ermöglicht, wogegen die übrigen Führungsnuten entlang der Längsachse des Teilungsrevolvers entsprechend vorbestimmten Standardabständen der Zuführorgane angeordnet sind.A further development of the invention is characterized in that the feed elements can be supported and fixed in these guide grooves by means of a dividing turret which can be rotated about an axis running transversely to the feed direction and which contains guide grooves distributed over its circumference, one of the guide grooves allowing freely selectable distances between the feed elements , whereas the other guide grooves are arranged along the longitudinal axis of the division revolver according to predetermined standard distances of the feed elements.

Die Vorrichtung gemäß der Erfindung ermöglicht es, die Lage der Seitenwände der Zuführkanäle zueinander sowie die Breite der Zuführkanäle je nach Bewegung und Stellung der Führungselemente unterschiedlich zu gestalten. Insbesondere sind die Bewegungsbereiche aller Seitenwände der Zuführkanäle im Zusammenspiel mit den Seitenwänden der benachbarten Zuführkanäle, d.h. unter Veränderung der Breite des jeweiligen, benachbarten Zuführkanals, erweiterbar und an unterschiedliche Längselementdurchmesser und Längselementteilungen optimal anpaßbar. Erfindungsgemäß können somit die Längselemente aus Zuführpositionen mit festgelegten, unveränderlichen Querabständen an Zuführorgane mit beliebig einstellbaren Querabständen übergeben werden, die beispielsweise bei Schweißmaschinen für die Herstellung von Gittermatten mit beliebig wählbarer Längsdrahtteilung Anwendung finden. Die Längselemente können beliebige Querschnittform haben, d.h. beispielsweise aus Runddrähten für die Herstellung von Gittermatten oder aus Flachbändern für die Herstellung von Gitterrosten bestehen. Zugleich ist es mit Hilfe der erfindungsgemäßen Vorrichtung möglich, den Zuführorganen der Schweißmaschine Längselemente in Form von Einzel- und Doppelelementen zuzuführen.The device according to the invention makes it possible to design the position of the side walls of the feed channels relative to one another and the width of the feed channels differently depending on the movement and position of the guide elements. In particular, the ranges of movement of all side walls of the feed channels are in interaction with the side walls of the adjacent feed channels, that is, by changing the width of the respective, adjacent feed channel, expandable and optimally adaptable to different longitudinal element diameters and longitudinal element divisions. According to the invention, the longitudinal elements can thus be transferred from feed positions with fixed, unchangeable transverse distances to feed elements with arbitrarily adjustable transverse distances, which are used, for example, in welding machines for the production of lattice mats with any desired longitudinal wire pitch. The longitudinal elements can have any cross-sectional shape, that is to say, for example, consist of round wires for the production of mesh mats or of flat strips for the production of gratings. At the same time, the device according to the invention makes it possible to feed longitudinal elements in the form of single and double elements to the feed elements of the welding machine.

In den Figuren sind die an sich bekannten Antriebs- und Verstelleinrichtungen, die hydraulisch, pneumatisch, elektromotorisch, aber auch händisch betätigbar sein können, der Übersicht halber weggelassen.In the figures, the drive and adjustment devices known per se, which can be operated hydraulically, pneumatically, by electric motor, but also by hand, have been omitted for the sake of clarity.

Gemäß den Fig. 1 und 2 werden Längselemente L, z.B. Längsdrähte, von einem nicht dargestellten Zuführwagen in der zur Herstellung einer Gittermatte od. dgl. notwendigen Anzahl sowie in dem dem Gittermattenaufbau entsprechenden Querabstand in Richtung des Pfeiles P Einführtrichtern 1 zugeführt. Die Zuführbahnen der Längselemente L fluchten mit den Öffnungen der Einführtrichter 1. Je Einführtrichter wird nur ein Längselement L zugeführt.1 and 2, longitudinal elements L, e.g. Longitudinal wires, from a feed trolley, not shown, in the number necessary for the production of a mesh mat or the like. As well as in the transverse distance corresponding to the mesh structure in the direction of the arrow P, feed funnels 1 are fed. The feed paths of the longitudinal elements L are aligned with the openings of the insertion funnel 1. Only one longitudinal element L is fed to each insertion funnel.

Die Einführtrichter 1 liegen parallel zur Schweißlinie S der Schweißmaschine nebeneinander in der durch die Zuführbahnen der Längselementeschar definierten Vorschubebene E-E. Die Anzahl der Einführtrichter 1 entspricht zweckmäßig der größten Anzahl von Längselementen L, die von der nachgeschalteten Schweißmaschine verarbeitet werden können. Der gegenseitige Abstand der Einführtrichter 1 ist jeweils konstant und stimmt zweckmäßig mit der kleinstmöglichen Grundteilung der Elektroden der Gitterschweißmaschine überein. Die Einführtrichter 1 sind um eine Achse 2 in Richtung des Pfeiles P₁ senkrecht zur Vorschubebene schwenkbar mit einem Gestell 3 verbunden, das in Richtung des Pfeiles P₂ längsverschiebbar und in Richtung des Pfeiles P₃ höhenverstellbar auf einem in Richtung des Pfeiles P₄ längsverschiebbaren Grundgestell 4 angeordnet ist.The insertion funnels 1 lie parallel to the welding line S of the welding machine next to one another in the feed plane defined by the feed paths of the longitudinal elements EE. The number of insertion funnels 1 suitably corresponds to the largest number of longitudinal elements L that can be processed by the downstream welding machine. The mutual distance between the insertion funnels 1 is constant in each case and suitably corresponds to the smallest possible basic pitch of the electrodes of the grid welding machine. The insertion funnel 1 are pivotally connected about an axis 2 in the direction of arrow P₁ perpendicular to the feed plane with a frame 3 which is longitudinally displaceable in the direction of arrow P₂ and height-adjustable in the direction of arrow P₃ on a base frame 4 which is longitudinally displaceable in the direction of arrow P₄.

An dem der Schweißmaschine zugekehrten Ende jedes Einführtrichters 1 sind seitlich zwei Führungselemente 5 angebracht, die hochkant senkrecht zur Vorschubebene E-E stehen und einen Zuführkanal K für je ein Längselement L begrenzen. Die Führungselemente 5 bestehen z.B. aus verschleißfesten Federstahlbändern, die an ihren freien Enden in der Vorschubebene E-E in Richtung des Pfeiles P₅ quer zur Vorschubrichtung P verschwenkbar sind. Die Länge der Führungselemente 5 wird so gewählt, daß bei extremer seitlicher Verschwenkung derselben auch Längselemente mit in der nachgeschalteten Schweißmaschine zu verarbeitenden größten Abmessungen ohne bleibende Verformung in den Zuführkanälen K gleiten können, ohne daß allzu große Reibungsverluste auftreten. Ein am Gestell 3 befestigtes Abschlußblech 6 begrenzt die Zuführkanäle K nach unten und verhindert damit ein Herausfallen der Längselemente L aus den Kanälen.At the end of each insertion funnel 1 facing the welding machine, two guide elements 5 are attached laterally, which are upright perpendicular to the feed plane E-E and limit a feed channel K for one longitudinal element L. The guide elements 5 are e.g. from wear-resistant spring steel strips, which can be pivoted at their free ends in the feed plane E-E in the direction of the arrow P₅ transversely to the feed direction P. The length of the guide elements 5 is selected so that, in the event of extreme lateral pivoting of the same, longitudinal elements with the largest dimensions to be processed in the downstream welding machine can slide in the feed channels K without permanent deformation, without excessive friction losses occurring. An end plate 6 fastened to the frame 3 limits the feed channels K at the bottom and thus prevents the longitudinal elements L from falling out of the channels.

Jeder Zuführkanal K mündet in ein rohrförmiges Zuführelement 7, das jeweils auf eine Schweißelektrode 8 der nachgeschalteten Schweißmaschine ausgerichtet und an einem Hubbalken 9 in Richtung des Pfeiles P₆ längsverschiebbar und in Richtung des Pfeiles P₇ querverschiebbar befestigt ist. Der Zuführkanal K ist außerdem durch einen um eine Achse 10 in Richtung des Pfeiles P₈ verschwenkbaren Verschlußdeckel 11 abgedeckt.Each feed channel K opens into a tubular feed element 7, which is aligned with a welding electrode 8 of the downstream welding machine and is longitudinally displaceable on a lifting beam 9 in the direction of arrow P₆ and can be moved in the direction of arrow P₇. The feed channel K is also covered by a cover 11 which can be pivoted about an axis 10 in the direction of the arrow P₈.

Die Anzahl der Zuführrohre 7 stimmt zweckmäßig mit der größten Anzahl der in der Schweißmaschine verarbeitbaren Längselemente überein. Die Fixierung eines Zuführrohres 7 am Hubbalken 9 erfolgt mittels einer lösbaren Klemmeinrichtung 12. Der Hubbalken 9 ist in Richtung des Pfeiles P₉ höhenverstellbar am Grundgestell 4 montiert, wodurch die Lage des Zuführrohres 7 auf unterschiedliche Durchmesser der Längselemente eingestellt werden kann. Das Zuführrohr 7 ist außerdem auf einem in Richtung des Pfeiles P₁₀ um eine quer zur Vorschubrichtung verlaufende Achse drehbaren Teilungsrevolver 13 abgestützt. Der Teilungsrevolver 13 enthält an seinem Umfang verteilt mehrere Zentriernuten 14, 14', welche in zur Längsrichtung des Teilungsrevolvers 13 parallelen Reihen angeordnet sind. Auf diese Weise können mehrere, fest vorgegebene Standardabstände der Zuführrohre 7 und somit Standardteilungen der Längselemente L rasch und reproduzierbar eingestellt werden. Außerdem ist eine durchgehende, sich über die gesamte Länge des Teilungsrevolvers 13 erstreckende Führungsnut 14'' vorhanden, die eine stufenlose Querverschiebung der Zuführrohre 7 und somit eine stufenlose Einstellung der Längselementeteilung gestattet.The number of feed tubes 7 appropriately corresponds to the largest number of longitudinal elements that can be processed in the welding machine. A feed pipe 7 is fixed to the walking beam 9 by means of a releasable clamping device 12. The walking beam 9 is mounted on the base frame 4 in a height-adjustable manner in the direction of the arrow P₉, as a result of which the position of the feed pipe 7 can be adjusted to different diameters of the longitudinal elements. The feed pipe 7 is also supported on a dividing turret 13 which is rotatable in the direction of the arrow P 1₀ about an axis extending transversely to the feed direction. The dividing turret 13 contains a plurality of centering grooves 14, 14 ′ distributed around its circumference, which are arranged in rows parallel to the longitudinal direction of the dividing turret 13. In this way, a plurality of fixed, predetermined standard distances between the feed pipes 7 and thus standard divisions of the longitudinal elements L can be set quickly and reproducibly. In addition, there is a continuous guide groove 14 ″ extending over the entire length of the revolving turret 13, which allows a stepless transverse displacement of the feed tubes 7 and thus a stepless adjustment of the longitudinal element division.

An dem den Führungselementen 5 zugekehrten Ende des Zuführrohres 7 sind an beiden Seiten des Zuführrohres Leitbleche 15 befestigt, die das Zuführrohr 7 in Richtung zu den Führungselementen 5 hin entsprechend verlängern und diese in der Arbeitsstellung umschließen. Im Zuführrohr 7 sind eine V-förmige Längsnut sowie geeignete Federelemente vorgesehen, welche die Längselemente L in diese Nut drücken und somit eine genau reproduzierbare, exakt fixierte Lage der Längselemente bei ihrem Vorschub in die Schweißmaschine gewährleisten.At the end of the feed tube 7 facing the guide elements 5, guide plates 15 are attached on both sides of the feed tube, which lengthen the feed tube 7 in the direction of the guide elements 5 and enclose them in the working position. A V-shaped longitudinal groove and suitable spring elements are provided in the feed tube 7, which press the longitudinal elements L into this groove and thus ensure a precisely reproducible, exactly fixed position of the longitudinal elements as they are fed into the welding machine.

Bei Produktionsbeginn und bei jeder Änderung der Längselementteilung, die eine Verstellung der Schweißelektroden 8 in der Schweißlinie S erforderlich macht, werden folgende Schritte ausgeführt:
   Das Gestell 3 wird in Richtung des Pfeiles P₂ entgegen der Vorschubrichtung P der Längselemente L so weit aus der Arbeitsstellung zurückgezogen, bis sich die Führungselemente 5 aus den Leitblechen 15 der Zuführrohre 7 lösen und in ihre Ausgangslage parallel zur Vorschubrichtung P zurückfedern können. Anschließend wird das Grundgestell 4 in Richtung des Pfeiles P₄ ebenfalls entgegen der Vorschubrichtung P der Längselemente zurückgezogen, so daß sich die Zuführrohre 7 von den Schweißelektroden 8 der Schweißmaschine entfernen, um die nachfolgende Verstellung der Schweißelektroden 8 auf die gewünschte Längselementteilung zu ermöglichen. Anschließend wird die Klemmeinrichtung 12 gelöst und es werden gegebenenfalls die Zuführrohre 7 in Richtung des Pfeiles P₆ entgegen der Vorschubrichtung P zurückgezogen. Nach erfolgter Verstellung der Schweißelektroden 8 wird das Grundgestell 4 in Richtung des Pfeiles P₄ in seine Ausgangsstellung zurückgeschoben.The following steps are carried out at the start of production and each time the longitudinal element division changes, which makes it necessary to adjust the welding electrodes 8 in the welding line S:
The frame 3 is so far from in the direction of arrow P₂ against the feed direction P of the longitudinal elements L. Working position withdrawn until the guide elements 5 detach from the guide plates 15 of the feed pipes 7 and can spring back into their starting position parallel to the feed direction P. Subsequently, the base frame 4 is also retracted in the direction of the arrow P₄ against the feed direction P of the longitudinal elements, so that the feed tubes 7 are removed from the welding electrodes 8 of the welding machine in order to enable the subsequent adjustment of the welding electrodes 8 to the desired longitudinal element division. Subsequently, the clamping device 12 is released and the feed pipes 7 are optionally retracted in the direction of the arrow P₆ against the feed direction P. After adjustment of the welding electrodes 8, the base frame 4 is pushed back into its starting position in the direction of the arrow P₄.

Die Zuführrohre 7 werden aus den Führungsnuten 14, 14' des Teilungsrevolvers 13 herausgehoben und dieser wird je nach gewünschter Teilung der Längselemente im herzustellenden Gitter in Richtung des Pfeiles P₁₀ derart gedreht, daß die entsprechende Reihe von Führungsnuten 14, 14' oder die endlose Führungsnut 14 in die oben liegende Arbeitsstellung gebracht wird.The feed pipes 7 are lifted out of the guide grooves 14, 14 'of the dividing turret 13 and this is rotated in the grating to be produced depending on the desired division of the longitudinal elements in the direction of the arrow P₁₀ such that the corresponding row of guide grooves 14, 14' or the endless guide groove 14th is brought into the working position above.

Dann werden die Zuführrohre 7 durch entsprechende Querverschiebung in Richtung des Doppelpfeiles P₇ sowie anschließende Längsverschiebung in Richtung des Pfeiles P₆ mittels nicht dargestellter Zentrierhilfen auf die Schweißelektroden 8 einzentriert und mittels der Klemmeinrichtung 12 fixiert. Nicht benötigte Zuführrohre 7 können gegebenenfalls an den Rand der Produktionsebene in eine sogenannte Parkstellung geschoben werden.Then, the feed tubes 7 are centered on the welding electrodes 8 by means of a corresponding transverse displacement in the direction of the double arrow P₇ and a subsequent longitudinal displacement in the direction of the arrow P₆ and are fixed by means of the clamping device 12. Feed pipes 7 that are not required can optionally be pushed to the edge of the production level in a so-called parking position.

Anschließend wird der Verschlußdeckel 11 durch Verschwenken in Richtung des Pfeiles P₈ in die strichliert eingezeichnete Offenstellung bewegt und das Gestell 3 wird in Richtung des Pfeiles P₂ in seine ursprüngliche Ausgangslage zurückgeschoben. Von der Schweißmaschinensteuerung werden entsprechende Befehle an zweckmäßig auf den Einführtrichtern 1 angebrachte, nicht dargestellte Signalanzeigen gegeben, um der Bedienungsperson anzuzeigen, welche der Einführtrichter 1 für den zu produzierenden Gittermattentyp vom nicht dargestellten Zuführwagen mit Längselementen L beschickt werden und welche der Zuführkanäle K welchen Zuführrohren 7 zugeordnet werden müssen.Then the cover 11 is moved by pivoting in the direction of arrow P₈ in the open position shown in dashed lines and the frame 3 is pushed back in the direction of arrow P₂ in its original starting position. Corresponding commands are given by the welding machine controller to signal displays, not shown, which are expediently attached to the insertion funnels 1 in order to indicate to the operator which of the Insertion funnels 1 for the type of lattice mat to be produced are fed with longitudinal elements L from the feed carriage (not shown) and which of the feed channels K must be assigned to which feed tubes 7.

Eine derartige Zuordnung wird dadurch hergestellt, daß der entsprechende Einführtrichter 1 mit seinen beiden Führungselementen 5 in Richtung des Pfeiles P₁ in die strichliert eingezeichnete Stellung hochgeschwenkt wird und die freien Enden der Führungselemente 5 anschließend durch seitliches Verschwenken in Richtung des Pfeiles P₅ zwischen die Leitbleche 15 des entsprechenden Zuführrohres 7 eingelegt werden. Dabei werden, wie in Position D gezeigt, bei einer sogenannten Doppelschweißung, bei welcher zwei Längselemente L ohne Querabstand gemeinsam mit den Querelementen, z.B. Querdrähten, verschweißt werden, zwei Zuführkanäle K gemeinsam zwischen die Leitbleche -15 eines Zuführrohres 7 eingelegt.Such an assignment is made in that the corresponding insertion funnel 1 is pivoted up with its two guide elements 5 in the direction of arrow P 1 in the position shown in dashed lines and the free ends of the guide elements 5 are then pivoted sideways in the direction of arrow P₅ between the guide plates 15 of the corresponding feed tube 7 are inserted. Here, as shown in position D, in a so-called double welding, in which two longitudinal elements L without transverse spacing together with the transverse elements, e.g. Cross wires are welded, two feed channels K inserted together between the guide plates -15 of a feed tube 7.

In Fig. 2 sind die mit nur einem Längselement L beschickten Zuführrohre mit 7' bezeichnet, wobei auch gezeigt ist, daß Längselemente unterschiedlichen Durchmessers zugeführt werden können. Da in vielen Fällen in Abhängigkeit vom gewünschten Gittermattentyp nicht alle Einführtrichter 1 benötigt werden, werden diese Einführtrichter 1 keinem Zuführrohr 7 zugeordnet und auch nicht mit Längselementen L vom Zuführwagen beschickt. Abschließend werden die Zuführkanäle K durch Herabschwenken des Verschlußdeckels 11 in Richtung des Pfeiles P₈ von oben verschlossen, um auch in dieser Richtung einen Austritt der Längselemente zu verhindern.In FIG. 2, the feed pipes which are loaded with only one longitudinal element L are designated 7 ', it also being shown that longitudinal elements of different diameters can be fed. Since, in many cases, depending on the desired type of grid mat, not all of the insertion funnels 1 are required, these insertion funnels 1 are not assigned to a feed tube 7 and are also not loaded with longitudinal elements L from the feed carriage. Finally, the feed channels K are closed by swiveling down the closure lid 11 in the direction of the arrow P₈ from above in order to prevent the longitudinal elements from escaping in this direction as well.

Für jene Fälle, in denen eine Beschickung der Zuführrohre 7 direkt vom Zuführwagen erfolgen soll, können alle Zuführkanäle K durch Absenken des Gestells 3 in Richtung des Pfeiles P₃ aus der Vorschubebene E-E funktionslos werden.For those cases in which the feed pipes 7 are to be fed directly from the feed carriage, all feed channels K can become inoperative by lowering the frame 3 in the direction of arrow P 3 from the feed plane E-E.

Bei der in Fig. 2 dargestellten Ausführungsvariante der Vorrichtung sind die Einführtrichter 1 und auch die Führungselemente 5 in Richtung senkrecht zur Vorschubebene der Längselementeschar nicht verschwenkbar. Statt der Leitelemente 15 ist eine um eine Achse 17 in Richtung des Pfeiles P₁₁ verschwenkbare, U-förmig ausgebildete, unten offene Verschlußklappe 16 am Eingang jedes Zuführrohres 7 befestigt.In the embodiment variant of the device shown in FIG. 2, the insertion funnels 1 and also the guide elements 5 cannot be pivoted in the direction perpendicular to the feed plane of the longitudinal element group. Instead of the Guide elements 15 is a pivotable about an axis 17 in the direction of arrow P₁₁, U-shaped, open bottom closure flap 16 attached to the entrance of each feed tube 7.

Zur Änderung der Zuordnung der Zuführkanäle K zu den Zuführrohren 7 wird nach den oben beschriebenen Schritten statt des Hochschwenkens der Führungselemente 5 und Einlegens derselben in die Leitbleche 15 nunmehr die Verschlußklappe 16 in Richtung des Pfeiles P₁₁ zunächst hochgeschwenkt, die Führungselemente 5 werden entsprechend der gewünschten Zuordnung seitlich in Richtung des Pfeiles P₅ verschwenkt und anschließend durch Zurückschwenken der Verschlußklappe 16 in Richtung des Pfeiles P₁₁ in ihrer Lage fixiert. Danach werden wieder alle Zuführkanäle K durch Herabschwenken des Verschlußdeckels 11 in Richtung des Pfeiles P₈ nach oben hin abgeschlossen.To change the assignment of the feed channels K to the feed pipes 7, instead of pivoting up the guide elements 5 and inserting them into the guide plates 15, the closure flap 16 is now initially pivoted up in the direction of the arrow P 1, after the steps described above, the guide elements 5 are corresponding to the desired assignment laterally pivoted in the direction of arrow P₅ and then fixed in position by pivoting back the flap 16 in the direction of arrow P₁₁. Thereafter, all the feed channels K are closed again by swiveling the closure lid 11 down in the direction of the arrow P₈.

Es versteht sich, daß das erläuterte Ausführungsbeispiel verschiedentlich abgewandelt werden kann, ohne den Erfindungsgedanken zu verlassen; beispielsweise könnten anstelle der Federstahlbänder auch Bänder aus elastischem Kunststoff verwendet werden und es könnten die Zuführelemente andere als die gezeigte Form haben.It is understood that the illustrated embodiment can be modified in various ways without departing from the inventive concept; For example, instead of the spring steel strips, strips made of elastic plastic could also be used and the feed elements could have a shape other than that shown.
