Bending devices are then provided to bend the ends of the transverse rods. Reinforcement meshes produced in this way are particularly suitable for the mechanized production of reinforcement cages. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Herstellung von Bewehrungsgittern, insbesondere für die Fertigung von Bewehrungskäfigen für Betonplatten, welche eine Führung zur Aufnahme eines aus einem Drahtverteiler zugeführten Querdrahtes, Schweissvorrichtungen sowie ggf. Biegemittel zum Biegen von Querdrahtenden aufweist.The present invention relates to a device for producing reinforcement meshes, in particular for the manufacture of reinforcement cages for concrete slabs, which has a guide for receiving a cross wire fed from a wire distributor, welding devices and, if appropriate, bending means for bending cross wire ends.

Um Bewehrungskäfige herzustellen, werden zuerst ebene Gitter hergestellt, welche anschliessend zu Käfigen gebogen werden. Dabei werden drei Kanten des Käfigs jeweils aus einem Bereich der Gitterfläche gebildet und die vierte Kante durch die sich ursprünglich gegenüberliegenden Kanten des Bewehrungsgitters. Dafür müssen die im rechten Winkel zu dieser Kante verlaufenden Drahtenden umgebogen werden.In order to produce reinforcement cages, flat grids are first produced, which are then bent into cages. In this case, three edges of the cage are each formed from an area of the lattice surface and the fourth edge is formed by the edges of the reinforcement lattice that were originally opposite. To do this, the wire ends running at right angles to this edge must be bent.

Hier besteht nun bei herkömmlich gefertigten Bewehrungsgittern das Problem, dass die vom letzten, parallel zu einer Kante des ebenen Gitters verlaufenden Draht gegen aussen abstehenden Querdrahtenden unterschiedliche Längen aufweisen. Dies rührt unter anderem von der hohen Vorschubgeschwindigkeit des Querdrahtes bei der Richtphase vor dem Verschweissen mit den Längsdrähten, von unregelmässigen Aussenkonturen, resp. Durchmesser des Querdrahtes, vom Einfluss der Schneidevorrichtung und von der Genauigkeit der Richtmaschine selbst her. Damit ergeben sich auch unregelmässige Krümmungsradien und Längen beim Biegen dieser Enden, was schlussendlich zu Problemen bei der Bildung des Käfigs führt. Die so erstellten Käfige weisen grosse Toleranzen auf. Weiter müssen herkömmlicherweise für unterschiedliche Drahtdurchmesser jeweils unterschiedliche Biegedorne verwendet werden.The problem with conventionally manufactured reinforcement grids now is that the length of the wire running from the last wire running parallel to an edge of the flat grating to the outside protrudes to different transverse wire ends. This stems, among other things, from the high feed rate of the cross wire during the straightening phase before welding with the longitudinal wires, from irregular outer contours, respectively. Diameter of the cross wire, the influence of the cutting device and the accuracy of the straightening machine itself. This also results in irregular radii of curvature and lengths when these ends are bent, which ultimately leads to problems in the formation of the cage. The cages created in this way have large tolerances. Furthermore, different bending mandrels are conventionally required for different wire diameters be used.

Die Aufgabe der vorliegenden Erfindung bestand nun darin, eine Vorrichtung vorzuschlagen, mit welcher automatisch und zuverlässig die Querdrahtenden einer Seite von Bewehrungsgittern auf eine bestimmte Länge gebracht werden, damit sie problemlos gebogen werden können und dabei die obenerwähnten Nachteile vermieden werden.The object of the present invention was now to propose a device with which the transverse wire ends of one side of reinforcement grids are automatically and reliably brought to a certain length, so that they can be bent without any problems and the above-mentioned disadvantages are avoided.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass an der Führung ein Anschlagelement angeordnet ist, welches in Richtung der Längsachsen der zugeführten Querdrähte gegen deren Enden verschiebbar ist, um die dagegen anstossenden Drahtenden zueinander ausgerichtet in eine vorbestimmte Lage zurückzustossen. Damit wird erreicht, dass an einer Kante des Bewehrungsgitters die Querdrahtenden alle die gleiche Länge aufweisen.This object is achieved according to the invention in that a stop element is arranged on the guide, which can be displaced in the direction of the longitudinal axes of the supplied transverse wires against their ends in order to repel the wire ends abutting against one another in a predetermined position. This ensures that the transverse wire ends all have the same length on one edge of the reinforcement grid.

Bevorzugte Ausführungsformen der Erfindung ergeben sich aus den Ansprüchen 2 bis 6.Preferred embodiments of the invention result from claims 2 to 6.

Durch die erfindungsgemässe Vorrichtung lassen sich Bewehrungsgitter auf einfache Weise automatisch herstellen, welche anschliessend einfach und zuverlässig zu Bewehrungskäfigen gebogen werden können, wobei die Abmessungen der Käfige sehr genau eingehalten werden können. Durch diese erfindungsgemässe Vorrichtung lassen sich Bewehrungskäfige präzise, einfach und kostengünstig herstellen.With the device according to the invention, reinforcement grids can be automatically produced in a simple manner, which can then be bent simply and reliably into reinforcement cages, the dimensions of the cages being able to be kept very precisely. With this device according to the invention, reinforcement cages can be manufactured precisely, simply and inexpensively.

Von einer Drahtrolle wird ein Draht mittels Mitnehmerrollen abgewickelt und mit hoher Geschwindigkeit einer Schneideresp. Schervorrichtung zugeführt. Die Schervorrichtung schneidet den Draht zu Stäben von vorgegebener Länge ab. Unterhalb dieser Stäbe ist ein Bandförderer 1 vorgesehen, welcher die abgeschnittenen Stäbe zu einem Drahtverteiler 2 fördert, wie in Figur 1 schematisch dargestellt ist. Dieser Drahtverteiler 2 weist auf seinem Umfang Längsaufnahmeschlitze 2' auf, in welche jeweils ein Stab vom Bandförderer 1 eingebracht wird. Durch Rotation dieses Drahtverteilers 2 gelangen die Stäbe auf eine Halterung 3, von wo aus sie mittels einer Magnetvorrichtung an eine Querfuhrung 4 angezogen werden. An dieser Querfuhrung 4 ist ein Anschlagelement 5 verschiebbar angeordnet. Die Verschiebung kann beispielsweise, wie hier gezeigt, mittels einer Schraubenstange 6 erfolgen.A wire is unwound from a wire roll by means of driving rollers and a cutting spit is moved at high speed. Shear device fed. The shearing device cuts the wire into bars of a predetermined length. Below these bars, a belt conveyor 1 is provided, which conveys the cut bars to a wire distributor 2, as shown schematically in FIG. This wire distributor 2 has longitudinal receiving slots 2 ′ on its circumference, into each of which a rod is introduced by the belt conveyor 1. By rotating this wire distributor 2, the rods reach a holder 3, from where they are attracted to a transverse guide 4 by means of a magnetic device. A stop element 5 is arranged displaceably on this transverse guide 4. The displacement can, for example, as shown here, take place by means of a screw rod 6.

Über dieser Vorrichtung sind in vorgegebenen Abständen parallel zueinander liegende Längsdrähte 7 des zu bildenden Bewehrungsgitters angeordnet, welche längsverschiebbar sind. Mit diesen Längsdrähten 7 werden die an der Querführung 4 positionierten Stäbe als Querstäbe mittels einer Schweisseinrichtung 8, in der Figur 1 schematisch dargestellt, verbunden. Nach der Verschweissung erfolgt jeweils ein Vorschub der Längsdrähte 7 um eine vorgegebene Distanz, um den nächsten Querdraht anzubringen.Over this device are arranged at predetermined intervals parallel longitudinal wires 7 of the reinforcement grid to be formed, which are longitudinally displaceable. The rods positioned on the transverse guide 4 are connected to these longitudinal wires 7 as transverse rods by means of a welding device 8, shown schematically in FIG. 1. After the welding, the longitudinal wires 7 are advanced by a predetermined distance in order to attach the next cross wire.

Die Wirkungsweise des Anschlagelementes 5 wird in der Folge der Figuren 2 bis 5 nachfolgend beschrieben.The mode of operation of the stop element 5 is described below in the sequence of FIGS. 2 to 5.

In Figur 2 ist das Anschlagelement 5 in seiner Ausgangsstellung am Ende der Querführung 4 dargestellt. Dicht über der Querführung 4 verlaufen die Längsdrähte 7 des zu erstellenden Bewehrungsgitters. Ebenfalls über der Querführung 4 ist die Schweissvorrichtung angeordnet, welche hier der Übersichtlichkeit halber nicht dargestellt ist. Damit werden die Längsdrähte 7 mit den Querdrähten verschweisst. Ein neuer Querdraht 8 wird nun an die Richtkante der Querführung 4 gebracht. Dabei kommt sein Ende 8' weiter gegen das Anschlagelement 5 zu liegen, als die ausgerichteten Enden der bereits verschweissten Querdrähte des Bewehrungsgitters.In Figure 2, the stop element 5 is shown in its starting position at the end of the transverse guide 4. The longitudinal wires 7 of the reinforcement grid to be created run closely above the transverse guide 4. The welding device is also arranged above the transverse guide 4, which is not shown here for the sake of clarity. So that the longitudinal wires 7 are welded to the cross wires. A new cross wire 8 is now brought to the straightening edge of the cross guide 4. Its end 8 'comes to lie further against the stop element 5 than the aligned ends of the already welded transverse wires of the reinforcement grid.

Nun wird das Anschlagelement 5 gegen das Querdrahtende 8' hin bewegt, wie in Figur 3 mit einem Pfeil dargestellt. Sobald es in Anschlag mit dem Querdrahtende 8' kommt, verschiebt es auch den Querdraht 8 mit.Now the stop element 5 is moved towards the transverse wire end 8 ', as shown in Figure 3 with an arrow. As soon as it comes into contact with the cross wire end 8 ', it also moves the cross wire 8 with it.

Das Anschlagelement 5 und damit auch das Querdrahtende 8' werden bis zu einer definierten, einstellbaren Position verschoben, wie in Figur 4 gestrichelt dargestell. Damit werden alle Querdrahtenden des Bewehrungsgitters sehr präzise ausgerichtet und weisen bezüglich des äussersten Längsdrahtes 7' dieselbe Länge auf. In dieser Position wird der Querdraht 8 mit den Längsdrähten 7,7' verschweisst.The stop element 5 and thus also the transverse wire end 8 'are shifted to a defined, adjustable position, as shown in dashed lines in FIG. All cross wire ends of the reinforcement grid are thus aligned very precisely and have the same length with respect to the outermost longitudinal wire 7 '. In this position, the cross wire 8 is welded to the longitudinal wires 7, 7 '.

Während nun das Anschlagelement 5 wieder in seine Ausgangsposition zurückverschoben wird, wird das Bewehrungsgitter um den Querdrahtabstand über der Querführung 4 verschoben und eine neuer Querdraht 9 wird wieder auf der Querführung 4 positioniert, wie in Figur 5 gezeigt.While the stop element 5 is now pushed back into its starting position, the reinforcement grid is shifted by the cross wire distance above the cross guide 4 and a new cross wire 9 is positioned again on the cross guide 4, as shown in FIG.

Anschliessend an die Querführung 4 ist eine Biegevorrichtung vorgesehen, wie aus Figur 6 ersichtlich. Dabei ist auf der Seite des Anschlagelementes 5 eine festliegende Biegevorrichtung, beispielweise ein Biegedorn 10, vorhanden. Um diesen Biegedorn 10 werden mittels einer nicht gezeigten Einrichtung die Querdrahtenden aufgebogen. Auf der gegenüberliegenden Seite ist eine weitere Biegevorrichtung 11 für die Endabschnitte der Querdrähte vorhanden, welche in der Figur 7 detaillierter dargestellt ist.A bending device is provided after the transverse guide 4, as can be seen from FIG. 6. A fixed bending device, for example a bending mandrel 10, is present on the side of the stop element 5. The transverse wire ends are bent up around this bending mandrel 10 by means of a device, not shown. On the opposite side there is a further bending device 11 for the end sections of the transverse wires, which is shown in more detail in FIG.

Die Querdrahtenden dieser Seite weisen keine einheitliche Länge auf, was aber keine Rolle spielt, da sie hier um den äussersten Längsdraht 7'' gebogen werden. Für das Fixieren des Längsdrahtes 7'' sind eine Anzahl von Festhalteelementen 12 vorgesehen, welche mit einem Schlitten 13 verbunden sind. Der Schlitten 13 ist mittels einer Führungsleiste 14 vertikal bewegbar, und in dieser selbst längsverschiebbar angeordnet. Damit können die Festhalteelemente 12 von unten her durch das Bewehrungsgitter geführt werden und mit dem Längsdraht 7'' in Eingriff gebracht werden.The transverse wire ends on this side are not of uniform length, but this does not matter since they are bent here around the outermost longitudinal wire 7 ″. A number of retaining elements 12, which are connected to a slide 13, are provided for fixing the longitudinal wire 7 ″. The carriage 13 can be moved vertically by means of a guide bar 14, and is arranged in this way itself so as to be longitudinally displaceable. The retaining elements 12 can thus be guided through the reinforcement grid from below and brought into engagement with the longitudinal wire 7 ″.

Jedes Festhalteelement 12 weist einen zylinderförmigen Kopfteil mit einer Aufnahmenut 12' für den Längsdraht 7'' auf. Der Kopfteil ist zweiteilig ausgebildet, wobei zwei Zylinder mit unterschiedlichen Aussendurchmessern vorgesehen sind, und dient als Biegedorn. Je nachdem, welcher dieser Teile über einen Querdraht positioniert wird, wird ein unterschiedlicher Biegeradius der Querdrahtenden erzielt. Die Positionierung eines Kopfteiles der Festhalteelemente 12 kann durch längsverschieben des Schlittens 13 erzielt werden. Die Festhalteelemente 12 müssen dabei im gleichen Abstand wie die Querdrähte auf dem Schlitten 13 angeordnet sein. Das Biegen der Querdrahtenden erfolgt beispielsweise mittels eines geeignet betätigten Biegestabes 15. Nach erfolgter Biegung werden die Festhalteelemente 12 wieder vom Längsdraht 7'' gelöst und unterhalb der Bewehrungsgitterbenen in eine Parkierungsposition gefahren.Each retaining element 12 has a cylindrical head part with a receiving groove 12 'for the longitudinal wire 7''. The head part is formed in two parts, two cylinders with different outside diameters being provided, and serves as a bending mandrel. Depending on which of these parts is positioned over a cross wire, a different bending radius of the cross wire ends is achieved. The positioning of a head part of the holding elements 12 can be achieved by longitudinally displacing the slide 13. The retaining elements 12 must be arranged at the same distance as the cross wires on the carriage 13. The transverse wire ends are bent, for example, by means of a suitably actuated bending rod 15 Bending, the retaining elements 12 are released again from the longitudinal wire 7 ″ and moved into a parking position below the reinforcement grid planes.

Es ist klar ersichtlich, dass entweder nur einzelne Querdrähte gebogen werden können, wozu wenigstens ein Festhalteelement 12 vorgesehen sein muss, oder gleichzeitig eine grössere Anzahl von Querdrahtenden gebogen werden können, wozu eine entsprechende Anzahl von Festhalteelementen 12 vorgesehen sein müssen.It is clearly evident that either only individual transverse wires can be bent, for which purpose at least one retaining element 12 must be provided, or at the same time a larger number of transverse wire ends can be bent, for which purpose a corresponding number of retaining elements 12 must be provided.

Derart hergestellte Bewehrungsgitter sind insbesondere geeignet für die Herstellung von Bewehrungskäfigen.Reinforcement meshes produced in this way are particularly suitable for the production of reinforcement cages.
