Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Maschine gemäss Oberbegriff des Anspruchs 1, sowie ein Verfahren gemäss Anspruch 4 zur kontinuierlichen Herstellung von Bewehrungskörben für Stahlbetonrohre, -masten, -pfähle und dergleichen mit Einrichtungen zur Zuführung der Längsdrähte und des Wendeldrahtes der Bewehrungskörbe. Die Querschnittsform der Körbe kann kreisrund, aber auch nichtkreisrund, elliptisch oder polygonal sein.The invention relates to a machine according to the preamble of claim 1, and a method according to claim 4 for the continuous production of reinforcement cages for reinforced concrete pipes, masts, piles and the like with means for feeding the longitudinal wires and the helical wire of the reinforcing cages. The cross-sectional shape of the baskets may be circular, but also non-circular, elliptical or polygonal.

Stand der TechnikState of the art

Schweißvorrichtungen für Bewehrungskörbe werden durch verschiedene Bauarten realisiert. Dabei kann die Schweißeinrichtung ortsfest, oder auf einem beweglichen Schlitten montiert sein, während sich die Längsdrähte in einer Vorrichtung drehen und gleichzeitig in Richtung der Längsachse des zu fertigenden Korbes bewegt werden, bei gleichzeitiger Umwicklung mit einer Drahtwendel und Verschweißung an den Kreuzungspunkten. Eine solche Vorrichtung ist z.B. in der US 3 718 797 f ür die Fertigung von Bewehrungskörben mit Muffen beschrieben.Welding devices for reinforcement cages are realized by different types. In this case, the welding device can be fixed, or mounted on a movable carriage, while the longitudinal wires rotate in a device and are simultaneously moved in the direction of the longitudinal axis of the basket to be produced, while winding with a wire helix and welding at the crossing points. Such a device is eg in the US 3,718,797 f For the production of reinforcement cages with sleeves described.

Oder aber die Schweißeinrichtung rotiert um den Bewehrungskorb mit seinen Längsdrähten herum, die von einer Zuführung vorgeschoben oder durch eine geeignete Vorrichtung gezogen werden. Auch bei diesem Arbeitsprinzip wird der Wendeldraht mit den Längsdrähten an den jeweiligen Kreuzungspunkten verschweißt.Or, the welder rotates around the rebar basket with its longitudinal wires being advanced by a feeder or pulled by a suitable device. Also in this working principle, the helical wire is welded to the longitudinal wires at the respective crossing points.

Maschinen des letztgenannten Arbeitsprinzips sind beispielsweise aus der DE 2631450 C2 bekannt.Machines of the latter working principle are for example from the DE 2631450 C2 known.

Auch in der DE 195 35 547 A1 wird eine Maschine zur Fertigung von insbesondere polygonalen Bewehrungskörben mittels einer umlaufenden Schweißvorrichtung beschrieben, die eine Schweißvorichtung auf einem radial zur Korblängsachse verschiebbaren Schlitten aufweist, und bei der gleichzeitig die Schweißrolle durch einen Hebel mittels einer Feder mit gleichmäßgem Druck an die Schweißstelle angepreßt wird.Also in the DE 195 35 547 A1 a machine for the production of particular polygonal reinforcement baskets is described by means of a rotating welding device having a Schweißvorichtung on a radially displaceable to Korblängsachse slide, and at the same time the welding roller is pressed by a lever by means of a spring with uniform pressure to the weld.

Um das Arbeitsprinzip und die Erfindung besser deutlich zu machen, ist als Beispiel in Fig. 1 in der Seitenansicht und in Fig. 2 in der Aufsicht von vorne eine Schweißmaschine gemäss Stand der Technik dargestellt, bei der die Schweißeinrichtung um die Längsdrähte rotiert.To better illustrate the principle of operation and the invention is given as an example in Fig. 1 in the side view and in Fig. 2 in front view of a welding machine according to the prior art shown, in which the welding device rotates about the longitudinal wires.

Die Maschine dient der Herstellung von Bewehrungskörben für die schon weiter oben genannten Betonfertigteile und hat einen Spulenständer 1, an dem die erforderliche Anzahl Drahtspulen 2, entsprechend der vorgesehenen Anzahl der Längsdrähte 3 angeordnet sind. Von diesen Drahtspulen werden die Längsdrähte 3 abgezogen und durch ein Drahtvorschubgerät 4 geführt in dem sie von Transportrollen erfasst und in bereits ausgerichteter Lage vorgeschoben werden.The machine is used to produce reinforcement baskets for the precast concrete components already mentioned above and has a coil stand 1 on which the required number of wire coils 2, corresponding to the intended number of longitudinal wires 3, are arranged. From these wire coils, the longitudinal wires 3 are withdrawn and guided by a wire feeder 4 in which they are detected by transport rollers and advanced in already aligned position.

Die Längsdrähte 3 werden dann durch eine Lehre 5 geführt, die im Innenraum eines hohlen, kreisförmigen Teiles 6 eines Ständers 9 angeordnet ist.The longitudinal wires 3 are then passed through a gauge 5, which is arranged in the interior of a hollow, circular part 6 of a stand 9.

In der Lehre 5 sind radial verlaufende Schlitze 7 vorgesehen, an denen Führungsstücke 8 radial verschiebbar angeordnet sind. Durch die Schlitze 7 und durch Ausnehmungen in den Führungsstücken 8 werden die Längsdrähte 3 geführt.In the teaching 5 radially extending slots 7 are provided on which guide pieces 8 are arranged radially displaceable. Through the slots 7 and through recesses in the guide pieces 8, the longitudinal wires 3 are guided.

Am kreisförmigen Teil 6 des Ständers 9 ist stirnseitig eine Ringscheibe 10 drehbar gelagert. Sie trägt an ihrem Umfang einen (nicht dargestellten) Zahnkranz, in den das (nicht dargestellte) Antriebzahnrad eines (nicht dargestellten) Getriebes eingreift.On the circular part 6 of the stator 9, an annular disc 10 is rotatably mounted on the front side. It carries at its periphery a (not shown) sprocket into which engages the (not shown) drive gear of a (not shown) gear.

An der Ringscheibe 10 ist ein radial verstellbarer Träger 11, der die Schweißeinrichtung 12 trägt, über Linearführungen 13 befestigt und läuft mit der Ringscheibe um. An ihr ist außerdem eine drehbare Drahtspule 14 gelagert, von welcher ein Draht 15 für eine den herzustellenden Bewehrungskorb umgebende Wendel abgezogen wird. An der Ringscheibe ist außerdem ein Kühlaggregat 16 vorgesehen, von welchem aus den Elektroden der Schweißeinrichtung 12 Kühlflüssigkeit zugeleitet wird.On the annular disc 10, a radially adjustable support 11, which carries the welding device 12, mounted on linear guides 13 and rotates with the annular disc. At her also a rotatable wire spool 14 is mounted, from which a wire 15 is subtracted for a coil surrounding the reinforcing cage to be produced. On the annular disc, a cooling unit 16 is also provided, from which 12 of the electrodes of the welding device coolant is supplied.

Zur Einstellung verschiedener Durchmesser des zu fertigenden Bewehrungskorbes sind die Führungsstücke 8 in den Schlitzen 7 sowie der Träger 11 mitsamt der Schweißeinrichtung 12 radial und stufenlos verstellbar.To set different diameter of the reinforcing cage to be manufactured, the guide pieces 8 in the slots 7 and the carrier 11 together with the welding device 12 are radially and continuously adjustable.

Diese Verstellung kann automatisch gesteuert werden, um den Korbdurchmesser während der Herstellung ändern zu können, z.B. für Bewehrungskörbe für Betonrohre mit im Durchmesser erweiterten Muffen.This adjustment can be automatically controlled to change the basket diameter during manufacture, e.g. For reinforcement cages for concrete pipes with enlarged diameter sleeves.

Der Träger 11 und die Führungsstücke 8 bewegen sich dabei synchron in eine Richtung, entweder radial nach außen vom Korbzentrum weg oder radial nach innen zum Korbzentrum hin.The carrier 11 and the guide pieces 8 move synchronously in one direction, either radially outward from the basket center away or radially inwardly towards the basket center.

Zur Herstellung von Bewehrungskörben, die vom kreisrunden Querschnitt abweichen, werden die Führungsstücke 8 in der Lehre 5 auf die entsprechende Kontur der gewünschten Form des Korbes voreingestellt. Die Schweißeinrichtung 12 folgt während des Umlaufs der Ringscheibe während der Korbherstellung radial dieser Kontur. Dies wird dadurch erreicht, dass der Träger 11 mit der darauf angeordneten Schweißeinrichtung 12 ständig radial durch einen Antrieb 17 während des Umlaufs der Ringscheibe 10 derart verstellt wird, dass die Schweißeinrichtung 12 nach Erreichen der jeweiligen Winkelposition des entsprechenden Führungsstückes 8 am Kreuzungspunkt des entsprechenden Längsdrahtes mit dem Wendeldraht zu liegen kommt.For the production of reinforcement cages, which differ from the circular cross-section, the guide pieces 8 are preset in the teaching 5 to the corresponding contour of the desired shape of the basket. The welding device 12 follows during the circulation of the annular disc during basket production radially of this contour. This is achieved in that the carrier 11 with the welding device 12 disposed thereon is constantly adjusted radially by a drive 17 during the circulation of the annular disc 10 such that the welding device 12 after reaching the respective angular position of the corresponding guide piece 8 at the intersection of the corresponding longitudinal wire comes to lie on the helical wire.

Die Steuerung des Antriebs 17 wird dabei von einem auf der Ringscheibe 10 angeordneten Steuergerät 20 übernommen.The control of the drive 17 is taken over by a arranged on the annular disc 10 controller 20.

Zur Positionsbestimmung der auf der Ringscheibe 10 angeordneten Schweißeinrichtung 12 sind dazu Schaltnocken 21 in der gleichen Anzahl wie Führungsstücke 8 auf dem kreisförmigen Teil 6 des Ständers 9 angeordnet. Während des Umlaufs der Ringscheibe 10 werden diese Schaltnocken 21 von einem auf, der Ringscheibe 10 angeordneten, elektrischen Schalter 22 nach der Schweißung überfahren und lösen ein Signal am Steuergerät 20 aus, welches den Befehl an den Antrieb 17 gibt den Träger 11 mit der darauf angeordneten Schweißeinrichtung 12 auf die Position des am nächsten liegenden Führungsstücks 8 zu fahren.For determining the position of the arranged on the annular disc 10 welding device 12 switching cam 21 are arranged in the same number as guide pieces 8 on the circular part 6 of the stator 9. During the circulation of the annular disc 10, these switching cam 21 are driven over by an on, the annular disc 10, electrical switch 22 after welding and trigger a signal on the control unit 20, which gives the command to the drive 17, the carrier 11 with the arranged thereon Welding device 12 to drive to the position of the nearest guide piece 8.

Während bei der Fertigung von kreisrunden Körben die Geschwindigkeit der Radialverstellung des Trägers 11, die sich aus der Durchmesseränderung des Korbes über die Korblänge und der Drahtvorschubgeschwindigkeit der Längsdrähte ergibt, relativ klein ist, treten bei der Fertigung von nichtkreisrunden Körben, bedingt durch die hohe Umfangsgeschwindigkeit der Ringscheibe 10 und der ständigen radialen Nachführung des Trägers 11 entlang der Korbkontur während des Umlaufs, erheblich höhere Geschwindigkeiten auf. Der Träger 11 muss dabei beispielsweise während eines Umlauf bei der Fertigung elliptischer Körbe, viermal radial die halbe Differenz der Achsmaße der Ellipse überwinden.While in the production of circular baskets, the speed of the radial displacement of the carrier 11, resulting from the change in diameter of the basket over the basket length and the wire feed speed of the longitudinal wires is relatively small, occur in the production of non-circular baskets, due to the high peripheral speed of Ring disc 10 and the constant radial tracking of the carrier 11 along the basket contour during the circulation, much higher speeds. The carrier 11 must overcome, for example, during a revolution in the production of elliptical baskets, four times radially half the difference in the axial dimensions of the ellipse.

Nach erfolgter Schweißung fährt der Antrieb 17 den Träger 11 mit der maximal erreichbaren Beschleunigung an die Position des nächsten Führungsstückes 8.After welding, the drive 17 moves the carrier 11 with the maximum achievable acceleration to the position of the next guide piece. 8

Die Signalübertragung zur Steuerung solcher Antriebe erfolgt üblicherweise bei derartigen Systemen über geschirmte Leitungen. Da der Antrieb 17 auf einer umlaufenden Ringscheibe 10 angeordnet ist und, bedingt durch die Nähe der Schweißeinrichtung 12, hohe elektromagnetische Störungen auftreten, können Steuersignale vom festen Ständer 9 der Maschine auf die umlaufende Schweißeinrichtung in ihrer ursprünglichen Form nicht sicher und verwertbar übertragen werden. Die Signale zur Ansteuerung des Antriebs 17 müssen möglichst zeitgleich nach Ausgang beim Signalgeber am Steuergerät des Antriebs anliegen.The signal transmission to control such drives usually takes place in such systems via shielded cables. Since the drive 17 is arranged on a rotating annular disc 10 and, due to the proximity of the welding device 12, high electromagnetic interference occur, control signals from the fixed stand 9 of the machine on the rotating welding device in its original form can not be safe and usable be transmitted. The signals for driving the drive 17 must be present as possible after the output at the signal generator on the control unit of the drive.

Aus diesem Grund wird gemäß Stand der Technik ein Steuergerät 20 zur Steuerung des Antriebs 17 auf der umlaufenden Ringscheibe 10 angeordnet. Da das Steuergerät 20 von der Steuerung der Schweißmaschine entkoppelt ist und mithin kein Signal über die aktuelle Umlaufgeschwindigkeit der Ringscheibe 10 und somit der Position der Schweißeinrichtung 12 erfährt, muss der Antrieb 17 mit der maximal erreichbaren Beschleunigung den Träger 11 mit der darauf angeordneten Schweißeinrichtung 12 verschieben. Bei starker Exzentrizität des Korbquerschnitts, treten dabei hohe Beschleunigungen am Träger 11 auf, die durch den Antrieb 17 erreicht werden müssen. Der Antrieb 17 kann nur in begrenztem Umfang verstärkt werden, was zu einer Begrenzung der maximal erreichbaren Umlaufgeschwindigkeit der Ringscheibe 10 führt.For this reason, a control unit 20 for controlling the drive 17 on the rotating annular disc 10 is arranged according to the prior art. Since the control unit 20 is decoupled from the control of the welding machine and thus receives no signal about the current rotational speed of the annular disc 10 and thus the position of the welding device 12, the drive 17 with the maximum achievable acceleration the carrier 11 with the welding device 12 arranged thereon move , With strong eccentricity of the basket cross-section, while high accelerations occur on the carrier 11, which must be achieved by the drive 17. The drive 17 can only be reinforced to a limited extent, which leads to a limitation of the maximum achievable rotational speed of the annular disc 10.

Liegt, beispielsweise bei der Fertigung von nichtkreisrunden Körben, das nächste Führungsstück 8 vom vorhergehenden Führungsstück auf einem kleineren Radius, kann sicherheitshalber die Schweißeinrichtung 12 erst nach einem, durch die Geometrie der Schweißeinrichtung bestimmten, auf ihrer Umfangsbahn zurückgelegten Weg radial nach innen verschoben werden, um nicht mit dem vorhergehenden Führungsstück zu kollidieren. Dadurch wird der am Umfang zur Verfügung stehende Weg und damit die zur Verfügung stehende Zeit zur Verschiebung der Schweißeinrichtung 12 begrenzt.If, for example, in the production of non-circular baskets, the next guide piece 8 from the previous guide piece on a smaller radius, for safety's sake, the welding device 12 can be moved radially inward only after determined by the geometry of the welding device, traveled on its circumferential path to not to collide with the previous leader. As a result, the distance available on the circumference and thus the time available for displacing the welding device 12 is limited.

Bei einer gegebenen erreichbaren Beschleunigung des Trägers 11 durch den Antrieb 17 wird dadurch die Umlaufgeschwindigkeit der Ringscheibe 10 weiter eingeschränkt.For a given achievable acceleration of the carrier 11 by the drive 17, thereby, the rotational speed of the annular disc 10 is further limited.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt die Aufgabe zu Grunde, eine Maschine zur kontinuierlichen Herstellung von Bewehrungskörben für Stahlbetonrohre, -masten, - pfähle und dergleichen mit umlaufender Schweißeinrichtung so auszubilden, dass die durch die notwendige Radialverstellung der Schweißeinrichtung 12 auftretenden Beschleunigungskräfte so klein wie möglich gehalten werden. Weiterhin liegt der Erfindung die Aufgabe zugrunde, dass die Radialverstellung der Schweißeinrichtung 12 auf einer geregelten Bahn erfolgen soll, um auch dadurch die auftretenden Beschleunigungskräfte geringer zu halten. Die Signalübertragung zwischen den einzelnen Steuerungsbausteinen soll hierzu ohne zeitliche Verluste und/oder ohne störende elektromagnetische Einflüsse erfolgen.The invention is based on the object, a machine for the continuous production of reinforcing baskets for reinforced concrete pipes, masts, - piles and the like with peripheral welding device so that the occurring by the necessary radial adjustment of the welding device 12 acceleration forces are kept as small as possible. Furthermore, the invention is based on the object that the radial adjustment of the welding device 12 is to take place on a regulated path in order to keep the occurring acceleration forces thereby also lower. The signal transmission between the individual control blocks is intended for this purpose take place without time losses and / or without disturbing electromagnetic influences.

Darstellung der ErfindungPresentation of the invention

Die Aufgaben werden durch die im Kennzeichen der Ansprüche 1 und 4 angegebenen Merkmale gelöst.The objects are achieved by the features specified in the characterizing part of claims 1 and 4.

Ein wesentliches Merkmal der Erfindung ist es, daß hierzu, wie in Fig. 3 exemplarisch dargestellt, auf dem Träger 11 eine weitere, in radialer Richtung verschiebbare, kleinere Einrichtung 18 angeordnet wird.An essential feature of the invention is that for this purpose, as in Fig. 3 illustrated by way of example, on the carrier 11, a further, smaller device 18, which can be displaced in the radial direction, is arranged.

Dadurch können die radialen Verstellwege, die sich aus der Durchmesserverstellung des Korbes während des Betriebs bei sich ändernden Korbgrößen und der radialen Nachführung der Schweißeinrichtung 12 bei nichtkreisrunden Korbgeometrien zusammensetzen, entkoppelt werden.As a result, the radial adjustment paths, which consist of the diameter adjustment of the basket during operation with changing basket sizes and the radial tracking of the welding device 12 in non-circular basket geometries, can be decoupled.

Die in radialer Richtung verschiebbare Einrichtung 18 wird dazu mit einem eigenen Antrieb 19 ausgestattet, der es ermöglicht diese Einrichtung samt der darauf angeordneten Schweißeinrichtung 12 gesteuert an jeden beliebigen auf der Korbkontur liegenden Punkt hinzuführen.The displaceable in the radial direction device 18 is to be equipped with its own drive 19, which allows this device along with the welding device 12 arranged thereon guided to any point lying on the basket contour point.

Die verschiebbare Einrichtung 18 kann erheblich leichter gehalten werden als der Träger 11. Damit reduzieren sich die Beschleunigungskräfte, was unter anderem zu einer höheren möglichen Geschwindigkeit in der radialen Verstellung der Schweißeinrichtung 12 und mithin auch zu einer höheren möglichen Umlaufgeschwindigkeit der Ringscheibe 10 führt.The displaceable device 18 can be kept considerably lighter than the carrier 11. This reduces the acceleration forces, which among other things leads to a higher possible speed in the radial adjustment of the welding device 12 and thus also to a higher possible rotational speed of the annular disk 10.

Um bei einer Maschine zur Herstellung von Bewehrungskörben variablen Querschnitts eine geregelte Führung der Schweißeinrichtung 12 entlang der Korbkontur in Abhängigkeit der Umlaufgeschwindigkeit der Ringscheibe 10 zu gewährleisten, wird das Steuergerät 20 erfindungsgemäß auch bevorzugt nicht mehr auf der Ringscheibe angeordnet.In order to ensure a controlled guidance of the welding device 12 along the basket contour depending on the rotational speed of the annular disc 10 in a machine for the production of reinforcing baskets of variable cross-section, the control device 20 according to the invention preferably also no longer arranged on the annular disc.

Zur Synchronisation der radialen Verstellung der verstellbaren Einrichtung 18 mit der Umlaufgeschwindigkeit der Ringscheibe 10 wird ein Steuergerät mit einer Messvorrichtung, welche die Umlaufgeschwindigkeit und die Stellung der Ringscheibe misst, gekoppelt.To synchronize the radial adjustment of the adjustable device 18 with the rotational speed of the annular disk 10, a control unit with a measuring device which measures the rotational speed and the position of the annular disc, coupled.

Bekannt sind Verfahren der Signalübertragung von Signalgebern über Schleifringe, Kabel und Bussysteme und per Funksignal. Diese Medien sind geschirmt ausgeführt und/oder räumlich so angeordnet, dass elektromagnetische Einwirkungen, welche die Signale beeinflussen können, abgefangen werden.Are known methods of signal transmission from signalers on slip rings, cables and bus systems and by radio signal. These media are shielded and / or spatially arranged so that electromagnetic influences that can affect the signals are intercepted.

Bekannt ist auch, schwache Signale zu verstärken um elektrische Widerstände der Übertragungsmedien zu überwinden und Auswirkungen elektromagnetischer Störungen aus der Atmosphäre oder dem Netz auf ein irrelevantes Maß zu beschränken.It is also known to amplify weak signals to overcome electrical resistances of the transmission media and to limit the effects of electromagnetic interference from the atmosphere or the network to an irrelevant level.

Bei der bekannten Verwendung von Bussystemen kommt es durch die Umwandlung in Datenblöcke und die erreichbare Übertragungsrate der Signale zu einem zeitlichen Versatz zwischen Eingangssignal und Ausgangssignal, was bewirkt, dass die Regelung zeitverzögert erfolgt und der Regler ständig nachregelt und dadurch in Schwingungen gerät.In the known use of bus systems, it comes through the conversion into blocks of data and the achievable transmission rate of the signals to a temporal offset between the input signal and output signal, which causes the control is delayed and the controller constantly readjusted and thereby gets into vibration.

In Abhängigkeit der radialen Stellung der verstellbaren Einrichtung 18 werden phasenversetzte Impulse durch einen mit dem Antrieb 19 gekoppelten Impulsgeber 25 (siehe Fig. 4) erzeugt und in einer Sendeeinheit 23, die auf der Ringscheibe 10 angeordnet ist, verstärkt. Die Impulse sind bevorzugt bekannte TTL Rechtecksignale, werden nach dem bekannten RS-422 Verfahren übertragen und dienen zur Übertragung von Informationen über die momentane Position und Drehgeschwindigkeit des Antriebs 19 an eine Regeleinheit 27. Aus den TTL Signalen A/A' und B/B' werden im Impulsverstärker der Sendeeinheit 23 dann jeweils zweimal die beiden Differenzsignale A aus den beiden Signalen A/A' und B aus den beiden Signalen B/B' erzeugt. Beide Signalpaare schalten jeweils die Gates von zwei Schalttransistoren. Über diese Schalttransistoren fließt dann ein im Vergleich zu den Ausgangssignalen erhöhter Strom mit erhöhter Spannung. Dadurch entstehen je zwei identische Signale A und B, die über voneinander unabhängige Systeme an die Empfangseinheit 24 übertragen werden.Depending on the radial position of the adjustable device 18 phase-shifted pulses are coupled by a drive 19 coupled to the pulse generator 25 (see Fig. 4 ) and amplified in a transmitting unit 23 which is arranged on the annular disc 10. The pulses are preferably known TTL square wave signals, are transmitted according to the known RS-422 method and serve to transmit information about the instantaneous position and rotational speed of the drive 19 to a control unit 27. From the TTL signals A / A 'and B / B' In the pulse amplifier of the transmitting unit 23, the two difference signals A are then respectively generated twice from the two signals A / A 'and B from the two signals B / B'. Both pairs of signals respectively switch the gates of two switching transistors. Over this switching transistors then flows in comparison to the output signals increased current with increased voltage. This results in two identical signals A and B, which are transmitted to the receiving unit 24 via independent systems.

Die so verstärkten Signale werden über Schleifringe 26 und Schleifkontakte an die nicht auf der umlaufenden Ringscheibe 10 angeordnete Empfangseinheit 24 des auf der umlaufenden Ringscheibe 10 angeordneten Antriebs 19 übertragen. Die Empfangseinheit 24 besteht dabei aus einem Signalfilter und einem Modul zur Aufbereitung der Signale.The thus amplified signals are transmitted via slip rings 26 and sliding contacts to the not arranged on the rotating ring disk 10 receiving unit 24 of the arranged on the rotating annular disk 10 drive 19. The receiving unit 24 consists of a signal filter and a module for processing the signals.

Im Modul zur Aufbereitung der Signale fließt der vom Impulsverstärker der Sendeeinheit 23 ankommende Strom durch Widerstände, wodurch eine zum Strom proportionale Spannung entsteht.In the module for processing the signals, the current arriving from the pulse amplifier of the transmitting unit 23 flows through resistors, whereby a voltage proportional to the current is produced.

Aus den Rechteckimpulsen des Spannungsabfalls werden wieder, jeweils zweimal, die ursprünglichen Signalpaare A/A' und B/B' in einer Ausgangsstufe erzeugt. Die nachgeschaltete Regeleinheit 27 vergleicht jeweils die beiden Signalpaare A/A' und B/B' mit den parallel erzeugten, identischen Signalpaaren und generiert daraus die Steuersignale für die Drehzahl und die Stellung des Antriebs 19. Die Regeleinheit 27 erkennt dabei die Signale so, als ob der Impulsgeber 25 direkt an sie angeschlossen wäre.From the rectangular pulses of the voltage drop, the original signal pairs A / A 'and B / B' are again generated twice in each case in an output stage. The downstream control unit 27 compares the two signal pairs A / A 'and B / B' with the parallel generated, identical signal pairs and generates from it the control signals for the speed and the position of the drive 19. The control unit 27 detects the signals as if the pulse generator 25 would be connected directly to them.

Dadurch wird erreicht, dass Steuerbefehle zeitgleich oder nahezu zeitgleich mit ihrer Anforderung ausgeführt werden. Dies läßt auch bei zeitkritischen Positionieraufgaben der Schweißeinrichtung 12, bei denen Kollisionsgefahr von Bauteilen, insbesondere mit den Führungsstücken 8, besteht, eine genaue Führung der Schweißeinrichtung entlang der Korbkontur durch Koppelung der radialen Bewegungen der verstellbaren Einrichtung 18 mit der momentanen Position und Umlaufgeschwindigkeit der Ringscheibe 10 zu.This ensures that control commands are executed at the same time or almost simultaneously with their request. This also allows for time-critical positioning tasks of the welding device 12, in which there is a risk of collision of components, in particular with the guide pieces 8, an accurate guidance of the welding device along the basket contour by coupling the radial movements of the adjustable device 18 with the current position and rotational speed of the annular disc 10th to.

Die Regeleinheit 27 ist im übrigen gekoppelt mit der Regeleinheit 28 des Antriebs der umlaufenden Ringscheibe 10.The control unit 27 is otherwise coupled to the control unit 28 of the drive of the rotating annular disc 10th

Ein weiterer wirtschaftlicher Nutzen dieser Methode liegt darin, dass diese Art der Signalübertragung ohne zusätzliche Aufrüstung der Steuerung mit einem Bussystem und den damit verbundenen Softwareaufwendungen erreicht wird. Die Verstärkung der Signale stellt sicher, dass diese ohne weitere Schutzmaßnahmen in betriebsüblichen Umgebungen sicher übertragen werden.Another economic benefit of this method is that this type of signal transmission is achieved without additional upgrade of the controller with a bus system and associated software expenses. The amplification of the signals ensures that they are safely transmitted in normal operating environments without further protective measures.
