Abstract

The invention relates to a method and device for sorting out rolled, in particular, bar-shaped steel products (8), which contain faults and which have been inspected for faults and material identity using non-destructive testing methods, and the detected faults having been marked on the finished rolled product (2). The marking ensues before or after these rolled products are cut to the cooling bed length and then to the length desired by the customer. The invention provides that several parallel bars that are cut to the length desired by the customer are simultaneously guided through an optical marking identification device (9) whose detection signals prompt the automatic sorting out of the defective bars (8).

Description

Verfahren und Vorrichtung zum Aussortieren von gewalzten, insbesondere stabförmigen, mit Fehlern behafteten oder zu kurzen StahlproduktenMethod and device for sorting out rolled, in particular rod-shaped, defective or too short steel products

Die Erfindung betrifft ein Verfahren zum Aussortieren von gewalzten, insbesondere stabförmigen, mit Fehlern behafteten Stahlprodukten gemäß dem Oberbegriff des Patentanspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens .The invention relates to a method for rejecting rolled, in particular rod-shaped, flawed steel products according to the preamble of claim 1 and an apparatus for carrying out the method.

Bei der Produktion von beispielsweise Stabmaterial, das ausgehend von einem heißen Stahlklotz mittels mehrerer Walzgerüste auf die gewünschte Form (rund, polygonaler Querschnitt) und das gewünschte Maß heruntergewalzt wird, werden Walzendgeschwindigkeiten von bis zu 15 m/s erreicht. Der aus dem Fertigwalzgerüst mit einer derartigen Geschwindigkeit kommende Stab wird mittels einer Schere auf Kühlbettlängen geschnitten, wobei die abgelängten Stäbe seitlich auf das Kühlbett befördert werden und dort parallel nebeneinander zu liegen kommen. Nach ausreichender Abkühlung werden diese Stäbe dann auf Kundenlänge (beispielsweise 6 m) gesägt.In the production of rod material, for example, which is rolled down from a hot steel block to the desired shape (round, polygonal cross-section) and to the desired dimension using several roll stands, final rolling speeds of up to 15 m / s are achieved. The rod coming from the finishing mill at such a speed is cut to cooling bed lengths using scissors, the cut rods being conveyed laterally onto the cooling bed and coming to lie parallel to one another there. After sufficient cooling, these bars are then sawn to customer length (for example 6 m).

Üblicherweise werden diese auf Kundenlänge gesägten Stäbe im folgenden auf Innen- und Oberflächenfehler sowie Materialidentität untersucht, die Fehler auf den Stäben über den gesamten Umfang oder auch nur lokal markiert, und anschließend werden die fehlerhaften, nicht mehr reparablen Stäbe aus dem Produkti- onsprozess entfernt. Von grundlegender Bedeutung ist hierbei, dass der genannte Verfahrensablauf durch die Walzendgeschwindigkeit bestimmt wird, so dass für die ab dem Ablängen auf Kundenlänge erfolgenden Schritte nur wenig Zeit vorhanden ist, Produktionsablauf nicht unnötig verzögert oder unterbrochen werden soll .These rods, which have been sawn to customer length, are usually examined below for internal and surface defects and material identity, the defects on the rods are marked over the entire circumference or only locally, and then the faulty, irreparable rods are removed from the production process. It is of fundamental importance here that the process sequence mentioned is determined by the final roll speed, so that there is only little time for the steps which take place after being cut to length by the customer, Production process should not be unnecessarily delayed or interrupted.

Die Anmelderin hat Verfahren entwickelt, mit denen die Prüfung auf Innen- und Oberflächenfehler bereits während des Walzprozesses erfolgt, ohne diesen zu stören. Auch der Markierungspro- zess, d.h. insbesondere die farbliche Markierung der detektier- ten Fehler auf dem Stab, wurde von der Anmelderin automatisiert und in den Produktionsprozess integriert, wobei die Markierung entweder bereits direkt im Anschluss an den Austritt des heißen Stabes aus dem letzten Walzgerüst durchgeführt wird oder später auf dem kalten Stab. Dies gelingt dadurch, dass die detektier- ten Fehler nach Art und Ort in einem Rechner gespeichert werden, der dann die Markierungseinrichtung steuert.The applicant has developed methods with which the checking for internal and surface defects takes place during the rolling process without interfering with it. The marking process, i.e. In particular, the color marking of the detected defects on the rod was automated by the applicant and integrated into the production process, the marking either being carried out directly after the hot rod emerges from the last rolling stand or later on the cold rod , This is achieved by storing the detected errors by type and location in a computer which then controls the marking device.

Als Engpass verbleibt jedoch nach wie vor das Aussortieren der fehlerhaften Stäbe, da jeder auf Kundenlänge geschnittene Stab einzeln begutachtet werden muss und die Entscheidung über gut oder fehlerbehaftet unter der Maßgabe der oben angegebenen Produktionsgeschwindigkeit getroffen und der fehlerhafte Stab aus dem Produktionsprozess herausgeführt werden muss . Gleiches gilt für zu kurze Stäbe, da die Bildauswertung gleichzeitig zur Längenkontrolle genutzt werden kann.However, sorting out the defective rods remains as a bottleneck, since each rod cut to the customer's length has to be examined individually and the decision about good or defective has to be made in accordance with the above-mentioned production speed and the defective rod has to be removed from the production process. The same applies to rods that are too short, since the image evaluation can also be used for length control.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art so zu führen, dass der Aussortie- rungsprozess nicht nur nicht mehr ein Hemmschuh im Produktionsprozess ist sondern erheblich beschleunigt werden kann.The invention is therefore based on the object of carrying out a method of the type mentioned at the outset in such a way that the rejection process is not only no longer a stumbling block in the production process but can be considerably accelerated.

Die Erfindung löst diese Aufgabe gemäß dem kennzeichnenden Teil des Patentanspruchs 1 dadurch, dass mehrere parallel nebeneinander liegende, auf Kundenlänge geschnittene Stäbe gleichzeitig durch eine optische Markierungserkennungseinrichtung geführt werden, deren Detektionssignale die automatische Aussonderung der fehlerhaften Stäbe veranlassen.The invention solves this problem in accordance with the characterizing part of patent claim 1 in that a plurality of bars lying parallel to one another and cut to customer length are simultaneously passed through an optical marking detection device, the detection signals of which cause the defective bars to be automatically sorted out.

Mehrere, beispielsweise 6 auf Kühlbettlänge geschnittene Stäbe, die parallel nebeneinander liegen, werden gleichzeitig in Kun- denlängen aufgeteilt. Jeweils diese 6 nebeneinander liegenden Stäbe werden dann durch die Markierungserkennungseinrichtung gefahren. Erkennt diese Einrichtung auf einem oder mehreren der Stäbe eine die Aussortierung notwendig machende Markierung, wird ein Signal erzeugt, dass im folgenden die automatische Aussonderung veranlasst .Several, for example 6 bars cut to the length of the cooling bed and lying parallel next to one another, are simultaneously made in plastic divided into lengths. Each of these 6 bars lying next to one another are then moved through the marking recognition device. If this device recognizes on one or more of the rods a marking that makes sorting necessary, a signal is generated which then initiates the automatic sorting.

Dabei besteht die Möglichkeit, entweder die fehlerhaften Stäbe aus der Transportlinie zu entfernen und sie in den Schrott zu geben, oder aber die als gut detektierten Stäbe zu entfernen und sie nachfolgenden Behandlungsstationen zuzuführen, wie zum Beispiel der spektrometrischen Untersuchung, dem Entgraten, dem Richten, dem Etikettieren etc..It is possible to either remove the defective rods from the transport line and put them in the scrap, or to remove the rods that have been detected as good and to send them to subsequent treatment stations, such as spectrometric examination, deburring, straightening, labeling etc.

Dadurch, dass stets mehrere Stäbe die Markierungserkennungsein- richtung passieren können, multipliziert sich die zu Erkennung und Aussortierung zur Verfügung stehende Zeit.The fact that several bars can always pass through the marking recognition device multiplies the time available for recognition and sorting out.

Verschiedene Möglichkeiten zur Trennung von guten und fehlerhaften Stäben sind - allerdings nicht abschließend - durch die Merkmale der Ansprüche 2 bis 5 gegeben.Various possibilities for separating good and faulty bars are given, however not conclusively, by the features of claims 2 to 5.

Gemäß Anspruch 2 werden die als fehlerhaft erkannten Stäbe aus der Transportebene angehoben und mittels eines geeigneten Hebezeugs quasi abgeschöpft. Das Herausheben geschieht beispielsweise mittels unterhalb der Stäbe in den Transportrinnen angeordneten Stempeln beziehungsweise Hubzylindern.According to claim 2, the rods identified as defective are lifted out of the transport plane and virtually skimmed off by means of a suitable lifting device. The lifting takes place, for example, by means of punches or lifting cylinders arranged below the bars in the transport channels.

Alternativ werden gemäß Anspruch 3 die guten Stäbe angehoben, abgeschöpft und weiteren Behandlungsstationen (siehe oben) zugeführt, während die fehlerhaften Stäbe weiter transportiert werden, beispielsweise direkt in den Schrott, oder, wenn es sich lediglich um mit Oberflächenfehlern behaftete Stäbe handelt, zu entsprechenden Nachbearbeitungen .Alternatively, according to claim 3, the good bars are lifted, skimmed off and fed to further treatment stations (see above), while the faulty bars are transported further, for example directly into the scrap, or, if the bars are only affected by surface defects, to corresponding reworking ,

In ähnlicher Weise kann gemäß den Ansprüchen 4 und 5 verfahren werden. Hier werden die auszusortierenden Stäbe nach unten aus der Transportebene abgesenkt und von dort weiter transportiert. Eine weitere Alternative besteht darin, dass die Transportrinnen um ihre Längsachse kippbar ausgebildet sind, so dass die auszusortierenden Stäbe seitlich auf weitere TransportSysteme abgekippt werden können.A similar procedure can be followed according to claims 4 and 5. Here the bars to be sorted out are lowered downwards from the transport level and transported from there. Another alternative is that the transport channels are designed to be tiltable about their longitudinal axis, so that the bars to be sorted out can be laterally tilted onto further transport systems.

Die Erfindung löst die gestellte Aufgabe ebenfalls mittels einer Vorrichtung gemäß Anspruch 6.The invention also achieves the stated object by means of a device according to claim 6.

Vorteilhafte Ausführungsformen sind Gegenstand der Unteransprüche .Advantageous embodiments are the subject of the dependent claims.

Dabei kann die Markierungserkennungseinrichtung aus mindestens einer oberhalb der Transportebene der parallel nebeneinander liegenden Stäbe angeordneten Video-Kamera (mit analoger oder digitaler Aufnahmetechnik) bestehen, die die gesamte Breite der Transportstrecke aufnimmt.,The marking recognition device can consist of at least one video camera (with analog or digital recording technology) which is arranged above the transport plane of the parallel bars and which records the entire width of the transport route.

Bevorzugterweise ist jedoch jeder Transportbahn der parallel zueinander transportierten Stäbe eine eigene Kamera zugeordnet .However, each transport path of the rods transported parallel to one another is preferably assigned its own camera.

Die Kamera (s) ist/sind an einem die Transportstrecke portalartig überbrückenden Gestell angeordnet und verfügen über eine Bildauswerteelektronik, die wiederum mit der Aussortiervorrichtung zur Steuerung derselben verbunden ist.The camera (s) is / are arranged on a frame which bridges the transport route in the manner of a portal and has image evaluation electronics which in turn are connected to the sorting device for controlling the same.

Die Erfindung wird im folgenden anhand von Zeichnungen näher dargestellt und erläutert .The invention is illustrated and explained in more detail below with reference to drawings.

Mit dem Bezugszeichen 1 ist das letzte Walzgerüst einer Walzstraße bezeichnet. Das auf Endmaß gewalzte Produkt trägt das Bezugszeichen 2. Mittels einer Markierungseinrichtung 3, die über einen nicht dargestellten Rechner von einer in dem Walzgerüst 1 oder einem vorhergehenden Gerüst integrierten Prüfvorrichtung, die das Walzmaterial auf Innen- und Oberflächenfehler untersucht, gesteuert wird, werden im vorliegenden Beispiel die detektierten Fehler auf dem heißen Stab 2 mit Markierungen 20 kenntlich gemacht, bevor er mittels der Schere 4 auf Kühlbettlänge 5 geschnitten wird.The last rolling stand of a rolling mill is designated by reference number 1. The product rolled to its final dimensions bears the reference number 2. In the present, a marking device 3, which is controlled via a computer (not shown) by a test device integrated in the rolling stand 1 or a previous stand and which examines the rolling material for internal and surface defects, is controlled Example, the detected defects on the hot rod 2 are identified by markings 20 before they are cut to a cooling bed length 5 by means of the scissors 4.

Die auf Kühlbettlängen geschnittenen Stäbe 5 werden seitlich (Pfeil a) auf ein Kühlbett 6 transportiert.The rods 5 cut to cooling bed lengths are transported laterally (arrow a) onto a cooling bed 6.

Nach ausreichender Abkühlung werden die Stäbe mittels der angedeutet dargestellten Ablängvorrichtung 7 (Sägen) auf Kundenlänge 8 geschnitten.After sufficient cooling, the rods are cut to customer length 8 by means of the cutting device 7 (sawing) indicated.

Im vorliegenden Beispiel werden jeweils 6 auf Kundenlänge geschnittene Stäbe 8 parallel nebeneinander durch eine Markie- rungserkennungseinrichtung 9 gefahren. Die Markierungserken- nungseinrichtung 9 besteht aus an einem die Transportstrecke 10 portalartig überbrückenden Gestell 11 angeordneten sechs Videokameras 12. Die Videokameras 12 steuern über eine Bilderken- nungs-Soft wäre eine Aussortiervorrichtung 13, die in zwei Beispielen in den Figuren 2 und 3 dargestellt ist. Die als fehlerhaft erkannten Stäbe 8 ' werden hier ausgesondert . Das geschieht gemäß dem in Fig. 2 dargestellten Beispiel dadurch, dass die als fehlerhaft erkannten Stäbe 8' durch in den Transportrinnen 14 angeordneten Hubstempeln 15 aus der Transportebene herausgehoben werden. Unter die emporgehobenen Stäbe 8' wird ein an einem Kran hängendes Hebezeug 16, das mit einer Gabel 17 ähnlich der eines Hubstaplers ausgerüstet ist, gefahren. Die fehlerhaften Stäbe 8' werden abgehoben und wegtransportiert, während die fehlerfreien Stäbe 8 in den Transportrinnen 14 weitertransportiert werden, beispielsweise zum Bürsten, Richten, Etikettieren etc.In the present example, 6 rods 8 cut to customer length are passed in parallel next to one another through a marking recognition device 9. The marking detection device 9 consists of six video cameras 12 arranged on a frame 11 bridging the transport route 10 in a portal manner. The video cameras 12 control via an image recognition software would be a sorting device 13, which is shown in two examples in FIGS. 2 and 3. The rods 8 'identified as defective are discarded here. According to the example shown in FIG. 2, this takes place in that the rods 8 'identified as defective are lifted out of the transport plane by lifting rams 15 arranged in the transport channels 14. Under the raised rods 8 ', a hoist 16 hanging on a crane and equipped with a fork 17 similar to that of a forklift is moved. The faulty rods 8 'are lifted off and transported away while the error-free rods 8 can be transported further in the transport channels 14, for example for brushing, straightening, labeling, etc.

Eine zweite Alternative einer Aussortiervorrichtung ist in Fig. 3 dargestellt.A second alternative of a sorting device is shown in FIG. 3.

Bei dieser Ausführungsform werden die Transportrinnen 14 auf Hubzylindern 18 getragen. Die als fehlerhaft erkannten Stäbe 8' werden mitsamt der Transportrinne 14 aus der Transportebene nach unten abgesenkt. In dieser Position können die Stäbe 81 an eine nicht dargestellte weitere Transporteinrichtung zum Abtransport übergeben werden.In this embodiment, the transport channels 14 are carried on lifting cylinders 18. The rods 8 'identified as defective are lowered together with the transport trough 14 from the transport plane. In this position, the rods 8 1 can be transferred to a further transport device, not shown, for removal.

Im dargestellten Beispiel allerdings sind die Transportrinnen 14 seitlich kippbar ausgestaltet. Die fehlerhaften Stäbe 8' werden aus der Transportrinne 14 seitlich auf eine Abtransport- Vorrichtung 19 gekippt.In the example shown, however, the transport channels 14 are designed to be laterally tiltable. The faulty rods 8 'are laterally tilted out of the transport trough 14 onto a removal device 19.

Der Aussortiervorgang kann selbstverständlich auch auf andere Art und Weise erfolgen.The sorting process can of course also be carried out in another way.

Darüber hinaus kann sich das Absenken gemäß Fig. 4 bzw. das Anheben gemäß Fig. 2 natürlich auch auf die fehlerfreien Stäbe 8 beziehen, und die fehlerhaften Stäbe 8' verbleiben in den Transportrinnen 14, die sie beispielsweise direkt in den Schrott transportieren. In addition, the lowering according to FIG. 4 or the lifting according to FIG. 2 can of course also refer to the fault-free rods 8, and the faulty rods 8 'remain in the transport channels 14, which they transport, for example, directly into the scrap.
