Description

Anlage zum Prüfen von Rohren unter Benutzung von Rohrprüfpressen Moderne Rohrerzeugungsanlagen weisen eine hohe Produktion von kleineren Dimensionen auf (z. 13. hinter Reduzierwalzwerken), zu deren Bewältigung in der Prüferei vorzugsweise Mehrfach-Rohrprüfpressen Verwendung finden. System for testing pipes using pipe testing presses Modern pipe production plants show a high production of smaller dimensions on (e.g. 13th behind reducing mills), preferably to deal with them in the testing shop Find multiple pipe testing presses.

Claims (2)

Während auf Mehrfach-Rohrprüfpressen mit in engen Grenzen anstellbaren Prüfköpfen nur Rohre von annähernd gleicher Länge durchgesetzt werden können, benötigen Rohre stark unterschiedlicher Länge Mehrfach-Prüfpressen, deren Prüfköpfe einzeln über den gesamten Rohrlängenunterscbied anstellbar sein müssen. In diesem Falle nimmt das ständige und oft weite Verfahren der Prüfköpfe einen beträchtlichen Teil jener Zeit in Anspruch, die für das Prüfen der Rohre zur Verfügung steht. While on multiple pipe testing presses with adjustable within narrow limits Probes can only pass through pipes of approximately the same length Pipes of very different lengths Multiple test presses, their test heads individually must be adjustable over the entire pipe length. In this case the constant and often long movement of the probes takes up a considerable part the time available for testing the pipes. Da es unvermeidlich ist, daß sich Rohre unterschiedlicher Länge im Arbeitsfluß befinden und das Ausscheiden unpassender Rohre von Hand von einer gewissen Häufigkeit und einem gewissen Arbeitstempo ah nicht mehr möglich ist, wird erfindungsgemäß vorgeschlagen, einer Rohrprüfpresse eine Rohrsortiereinrichtung vorzuschalten. die Rohre, die von einer gewissen Länge abweichen, selbttätig ausscheidet. Since it is inevitable that pipes of different lengths will be in the Work flow and the elimination of unsuitable pipes by hand from a certain Frequency and a certain work pace ah is no longer possible, is according to the invention proposed to connect a pipe sorting device upstream of a pipe testing press. the Pipes that deviate from a certain length are eliminated automatically. Die Rohrsortiereinrichtung gemäß der Erfindung ist gekennzeichnet durch einen kontinuierlich laufenden Hubbalken- oder Kettentrieb, in dessen Bereich auf einer Seite eine Einrichtung - z. B. in Gestalt einer Leitschiene oder von Querrol'len - zum Ausrichten der Rohre angeordnet ist, während auf der anderen Seite einstellbare Fotozellen vorgesehen sind, die auf eine im Zuge der Ablaufbahn der Rolle liegenden Klappe einwirken, so daß durch deren Bewegung die ablaufenden Rohre entweder der Rohrprüfpresse zugeführt oder durch einen Ablaufmilgang abgeführt werden. The pipe sorting device according to the invention is characterized by a continuously running walking beam or chain drive in its area on one side a facility - z. B. in the form of a guardrail or Querrol'len - Is arranged for aligning the pipes, while on the other hand adjustable Photocells are provided, which are located on a roller in the course of the run-off path Act flap, so that by their movement, the draining pipes either the Pipe testing press can be fed in or removed through a drainage duct. Auf diese Weise kann man entweder Rohre, die von einer erforderlichen Fixlänge abweichen (für Mehrfach-Prüfpressen mit in engen Grenzen anstellbaren Prüfköpfen) oder Rohre, die außerhalb einer zugelassenen maximalen und minimalen Länge liegen (für Mehrfach-Prüfpressen mit einzeln und über eine größere Strecke anstellbaren Prüfköpfen), selbsttätig ausscheiden. This way one can either use pipes that are required by one Deviate from the fixed length (for multiple test presses with test heads that can be adjusted within narrow limits) or pipes that are outside an approved maximum and minimum length (for multiple test presses with individually adjustable ones over a longer distance Probes), drop out automatically. In der Zeichnung ist die Rohrsortiereinrichtung gemäß der Erfindung in Fig. 1 im Aufriß und in Fig. 2 im Grundriß prinzipiell dargestellt. In the drawing is the pipe sorting device according to the invention in Fig. 1 in elevation and in Fig. 2 in plan view in principle. Sie besteht aus einem Hubbalkentrieb 1, der im kontinuierlichen Betrieb die Rohre 2 einzeln einem Vorratslager 3 entnimmt und schrittweise auf quer zur Rohrachse und zwischen den Hubbalken befind- liche, angetriebene profilierte Rollen 4 befördert, welche die Rohre in einem oder erforderlichenfalls mehreren Schritten gegen einen festen Anschlag 5 fahren und dadurch an einem Ende auf gleiche Länge bringen. Beim nächsten Schritt gelangt Rohr um Rohr in den Wirkungsbereich von zwei Fotozellen 6, die auf die erforderlichen Rohrlängen einstellbar sind und die beim UTber-oder Unterschreiten der richtigen Rohrlängen über eine geeignete Schalteinrichtung eine im Rohrahlaufrost befindliche Klappe 7 derart steuern, daß dieselbe bei Rohren in der richtigen Länge geschlossen bleibt, bei Rohren unpassender Länge jedoch geöffnet wird und somit diese Rohre ausgeschieden werden. It consists of a walking beam drive 1, which is in continuous operation the tubes 2 individually removed from a storage 3 and gradually across to Pipe axis and between the walking beams. liche, driven profiled rollers 4, which conveys the pipes in one or, if necessary, several steps drive against a fixed stop 5 and thereby to the same length at one end bring. In the next step, tube after tube comes within the range of two Photocells 6, which are adjustable to the required pipe lengths and the Exceeding or falling below the correct pipe lengths via a suitable switching device control a flap 7 located in the tubular rust in such a way that the same in the case of pipes remains closed at the correct length, but open for pipes of unsuitable length and thus these pipes are excreted. PATENTANsPRÜcHE: 1. Anlage zum Prüfen von Rohren unter Benutzung von Rohrprüfpressen, dadurch gekennzeichnet, daß der Rohrprüfpresse eine Rohrsortiereinrichtung vorgeschaltet ist, die Rohre, die von einer gewissen Länge abweichen, selbsttätig ausscheidet. PATENT CLAIMS: 1. System for testing pipes in use of pipe testing presses, characterized in that the pipe testing press has a pipe sorting device is connected upstream, the pipes, which deviate from a certain length, automatically ruled out. 2. Rohrsortiereinrichtung nach Anspruch 1, gekennzeidmet durch einen kontinuierlich laufenden Hubbalken- oder Kettentrieb, in dessen Bereich auf einer Seite eine Einrichtung, z. 13. in Gestalt einer Leitschiene oder von Querrollen, zum Ausrichten der Rohre angeordnet ist, während auf der anderen Seite einstellbare Fotozellen vorgesehen sind, die auf eine im Zuge der Ablaufbahn der Rolle liegende Klappe einwirken, so daß durch deren Bewegung die ablaufenden Rohre entweder der Rohrprüfpresse zugeführt oder durch einen Ablaufrollgang abgeführt werden. 2. Pipe sorting device according to claim 1, gekennzeidmet by a continuously running walking beam or chain drive, in its area on a Side a facility, e.g. 13. in the form of a guardrail or cross rollers, is arranged for aligning the tubes, while on the other hand adjustable Photocells are provided, which are located on a in the course of the runway of the role Act flap, so that by their movement, the draining pipes either the Pipe testing press can be fed in or removed through a roller table.
