Description
Vorrichtung an Zulaufrollgängen für Wärmöfen zum periodischen Anhalten mehrerer, auf dem Rollgang kontinuierlich anfallender kurzer Walz- oder ähnlicher Erzeugnisse L)ie Erfindung bezieht sich auf das Beschicken von Wärmöfen mit auf einem Rollgang kontinuierlich hintereinander anlaufenden kurzen Walz- oder ähnlichen Erzeugnissen, und hier insonderheit auf eine Vorrichtung am Rollgang zum periodischen Anhalten mehrerer der erlnrähnten Erzeugnisse auf dem Rollgang, um sie gesammelt mittels einer magnetischen Blockeinsetzmaschine zu erfassen und gleichzeitig in das Ofeninnere einzubringen.Device on supply roller tables for heating ovens for periodic stopping several short rolling mills or similar that occur continuously on the roller table Products L) he invention relates to the loading of heating ovens with on one Roller table short rolled or similar products running continuously one after the other, and here in particular a device on the roller table for periodic stopping several of the products mentioned on the roller table in order to collect them by means of a magnetic block inserting machine and at the same time into the furnace interior bring in.
Bei der Beschickung von Wärmöfen mit auf einem Zulaufrollgang kontinuierlich anfallenden kurzen Walz- oder ähnlichen Erzeugnissen ist das Einbringen der Erzeugnisse als Einzelstücke sehr umständlich und zeitraubend, da das Einbringen eines jeden Stückes in den Ofen ein jedesmaliges Öffnen der Beschickungstür erfordert, was gleichzeitig auch einen großen Wärmestrahlungsverlust aus dem Ofeninnern bedeutet. Soweit man bereits vorgeschlagen hat, bei kurzen Walz- oder ähnlichen Erzeugnissen mehrere dierartige Erzeugnisse gleichzeitig in den Ofen einzubringen und dadurch den vorerwähnten Nachteil der Einzelbeschickung zu vermeiden, bereitet das gesammelte Erfassen und Einbringen der Walzstücke in den Ofen nicht geringe Schwierigkeiten und ist mit umständlichen Einrichtungen verbunden, die eine gesonderte zw sätzliche Bedienung erfordern und daher die Ofenbeschickung nicht unwesentlich verteuern. When charging heating furnaces with on a feed roller conveyor continuously Accruing short rolled or similar products is the introduction of the products very cumbersome and time-consuming as individual pieces, since the introduction of each one Piece into the oven requires opening the loading door each time, which is simultaneous also means a large loss of heat radiation from the interior of the furnace. As far as you can has already proposed several for short rolled or similar products to bring such products into the oven at the same time and thereby the aforementioned To avoid the disadvantage of the individual loading, the collected gathering prepares and Bringing the rolled pieces into the furnace is not easy and is with cumbersome facilities associated with a separate zw s additional operation require and therefore not insignificantly increase the cost of charging the furnace.
Gegenstand der Erfindung ist nun eine Vorrichtung an Zulaufrollgängen für Wärmöfen zum periodischen Anhalten mehrerer kontinuierlich anfallender kurzer Walz- oder ähnlicher Erzeugnisse auf dem Rollgang, der die vorerwähnten Nachteile nicht anhaften, indem auf dem Rollgang die in laufender Folge hintereinander ankommenden Erzeugnisse periodisch selbsttätig, der bekannten Anordnung der Magnete der Blockeinsetzmaschine entsprechend, angehalten werden, um alsdann von dieser gesammelt erfaßt und in das Ofeninnere eingebracht zu werden. Diese Vorrichtung besteht erfindungsgemäß aus mehreren je nach der Anzahl der gewünschten, gleichzeitig in den Ofen einzusetzenden Walz- oder ähnlichen Erzeugnisse entsprechenden, unterhalb der Rollen des Rollganges schwenkbar gelagerten Hebeln, die am vorderen Ende eine lose Rolle für den Auflauf des Walz- oder sonstigen Erzeugnisses besitzen, während sie am hinteren Ende einen Anschlag für das nachfolgende Walzgut aufweisen. Dabei besitzen die im Bereich eines jeden Schwenkhebels liegenden Rollen des Rollganges gesonderte Antriebe, die in der unbelasteten Normallage der Schwenkhebel durch diese eingeschaltet sind, um beim Hochdrücken des hinteren Schwenkhebelteiles durch Auflaufen des Walzgutes. auf die vordere lose Rolle der Hebel ausgeschaltet zu werden. The invention now relates to a device on feed roller tables for heating furnaces to periodically stop several continuously occurring short ones Rolled or similar products on the roller table that have the aforementioned disadvantages do not adhere to the rollers arriving one after the other on the roller table Products periodically automatically, the known arrangement of the magnets of the block inserting machine accordingly, are stopped in order to then collectively be grasped by this and transferred to the Furnace interior to be introduced. According to the invention, this device consists of several, depending on the number desired, to be placed in the oven at the same time Rolled or similar products below the rollers of the roller table pivoted levers that have a loose roll for the casserole at the front end of the rolled or other product, while they have a Have stop for the subsequent rolling stock. They own in the area of a each swivel lever lying rollers of the roller table separate drives, which in the unloaded normal position of the pivot levers are switched on by them when pushing up the rear swivel lever part due to the rolling stock. on the front loose roll of the lever to be turned off.
Hierdurch wird ein übermäßiges Verschleißen der innerhalb des Bereichs der Schwenkhebel liegenden angetriebenen Rollen vermieden. Die so periodisch angehaltenen und in kurzen Abständen auf dem Rollgang liegenden Walz- oder ähnlichen Erzeugnisse werden alsdann mittels einer mit mehreren Magneten versehenen Blockeinsatzmaschine gleichzeitig vom Rollgang abgehoben und auch gleichzeitig in den Wärmofen eingesetzt, wozu es dann nur eines einmaligen Öffnens der Ofenbeschickungstür bedarf.This will cause excessive wear and tear on the inside of the area the pivot lever avoided lying driven rollers. Those stopped so periodically and rolled or similar products lying on the roller table at short intervals are then by means of a block inserting machine provided with several magnets lifted off the roller table at the same time and inserted into the heating furnace at the same time, For which it is then only necessary to open the oven loading door once.
In der Zeichnung ist die erfindungsgemäße Vorrichtung in einem Ausführungsbeispiel schematisch in Seitenansicht veranschaulicht, und zwar in dem gezeichneten Beispiel mit vier Schwenkhebeln für das periodische Anhalten von vier mit beliebigen Zwischenräumen hintereinanderliegenden Walzerzeugnissen an beliebiger, im Bereich der Ofenbeschickung liegender Stelle des Rollganges. In the drawing, the device according to the invention is in one embodiment illustrated schematically in side view, namely in the drawn example with four swivel levers for periodic stopping of four with any gaps between them Rolled products lying one behind the other on any, in the area of the furnace loading lying point of the roller table.
Mit I sind die im Ofen zu erwärmenden, auf den Rollen 2 des Rollganges kontinuierlich anlaufenden Walzblöcke oder sonstige Erzeugnisse bezeichnet, und 3 sind die einseitig unterhalb der Rollen 2 gelagerten Schwenkhebel, die am vorderen Ende eine - lose Rolle 4 tragen, während sie am hinteren Ende einen Begrenzungsanschlag 8 besitzen, der zweckmäßig abnehmbar angeordnet ist, um im Bedarfsfalle weniger Anschläge benutzen zu können. With I are those to be heated in the oven on rollers 2 of the roller table continuously running rolling blocks or other products, and 3 are the pivot levers mounted on one side below the rollers 2, which are on the front End a - loose roller 4, while at the rear end a limit stop 8 have, which is conveniently arranged to be removable to less if necessary To be able to use stops.
In der Normallage liegen die Schwenkhebel 3 infolge ihrer einseitigen Lagerung durch ihr Eigengewicht schräg nach unten, wobei ihre Schräglage nach unten durch Anschläge 5 am Rollgangrahmen begrenzt ist. In dieser Lage drücken die Schwenkhebel 3 mit ihrem hinteren Ende auf die Schalter g der gesonderten Rollenantriebe und schalten letztere ein, so daß die Rollen 2 des Rollganges angetrieben sind, das Gut also den ganzen Rollgang überläuft, wobei jeweils die vorderen, etwas erhöht liegenden losen Rollen 4 an den Schwenkhebeln 3 vorübergehend in die Lauflage der Rollen 2 durch das Beschickungsgut gedrückt werden, um alsdann wieder in die erhöhte Anfangslage zurückzugehen, bevor das nächstfolgende Gut den vorübergehend gehobenen Anschlag 8 am hinteren Hebelteil erreicht hat. In the normal position, the pivot levers 3 are due to their one-sided Storage by its own weight obliquely downwards, with its oblique position downwards is limited by stops 5 on the roller table frame. In this position, the swivel levers press 3 with its rear end on the switch g of the separate roller drives and turn on the latter so that the rollers 2 of the roller table are driven, the So the whole roller table runs over well, with the front ones being slightly raised lying loose rollers 4 on the pivot levers 3 temporarily in the running position of the Rolls 2 are pushed through the load to then return to the increased Go back to the initial position before the next good is temporarily raised Has reached stop 8 on the rear part of the lever.
Hat nun der erste auf dem Rollgang anlaufende Walzblock I im Bereich der Beschickungsmaschine am Ende des Rollganges den festliegenden Anschlag7, beispielsweise in Form einer U-Schiene, erreicht und ist dadurch am Weiterlaufen verhindert, so bleibt die durch den Walzblock I herabgedrückte lose Rolle 4 in der niedergedrückten Lage in Höhe der Laufrollen 2, wobei der Schwenkhebel 3 die durch den Anschlag 6 am Rollgangrahmen begrenzte waagerechte Lage eingenommen hat. In dieser Lage hat der Schwenkhebel 3 einmal den Schalter g für den Rollenantrieb freigegeben und damit den Antrieb im Bereich des Schwenkhebels 3 ausgeschaltet, so daß nunmehr die Laufrollen 2 innerhalb des Hebels 3 zum Stillstand kommen, sodann aber auch verbleibt der Anschlag 8 am hinteren Ende des Schwenkhebels 3 in der erhöhten Lage, in der er dem nachfolgenden Block I als Anschlag dient. Es kann nunmehr auch der zweite Block I nicht mehr weiterlaufen, und es verbleibt die durch ihn belastete lose Rolle 4 am vorderen Hebelende ebenfalls in der niedergedrückten Lage, bei der der Antrieb der Rollen 2 ausgeschaltet ist und der Schwenkhebel 3 die waagerechte Lage eingenommeil hat, bei der der Anschlag 8 an seinem hinteren Ende wiederum als Begrenzung für den anlaufenden driften Block I dient. Dieser Vorgang wiederholt sich bei jedem weiteren Schwenkhebel 3. Nachdem nun in der erwähnten Weise mehrere Walzblöcke I auf dem Rollgang zum Stillstand gekommen sind und in einem bestimmten Abstand auf dem Rollgang liegen, werden sie von den über ihnen stehenden Magneten der Blockeinsetzmaschine erfaßt, vom Rollgang abgehoben und in den Ofen eingebracht. Nach erfolgtem Abheben der Blöcke I von den stillstehenden Rollen 2 fallen die Schwenkhebel 3 infolge ihres Eigengewichtes sofort wieder in dieUrsprungslage zurück, bei der die Begrenzungsanschläge 8 am hinteren Hebelende wieder aus dem Bereich der Rollen 2 und der Antrieb der Rollen 2 eingeschaltet ist. Dies geht so schnell vonstatten, daß das vorübergehende Anhalten von Walzblöcken I auf den Laufrollen 2 keinerlei Hemmnis für die nachfolgenden Blöcke bedeutet. Now has the first rolling block I approaching the roller table in the area the loading machine at the end of the roller table the fixed stop7, for example in the form of a U-rail, and is thus prevented from continuing, so the loose roller 4 depressed by the rolling block I remains in the depressed one Position at the level of the rollers 2, the pivot lever 3 being controlled by the stop 6 has assumed a limited horizontal position on the roller table frame. Has in this situation the pivot lever 3 once released the switch g for the roller drive and thus turned off the drive in the area of the pivot lever 3, so that now the rollers 2 come to a standstill within the lever 3, but then the stop also remains 8 at the rear end of the pivot lever 3 in the elevated position in which it is the following Block I serves as a stop. The second block I can no longer continue, and the loose roller 4 loaded by it also remains at the front end of the lever in the depressed position in which the drive of the rollers 2 is switched off and the pivot lever 3 has taken the horizontal position in which the stop 8 at its rear end in turn as a limit for the approaching drift block I serve. This process is repeated with every further swivel lever 3. After now several rolling blocks I on the roller table come to a standstill in the manner mentioned have come and lie on the roller table at a certain distance, they will captured by the magnets of the block inserting machine above them, from the roller table lifted off and placed in the oven. After lifting the blocks I from the stationary rollers 2, the pivot levers 3 fall immediately due to their own weight back to the original position, in which the limit stops 8 at the rear The end of the lever is out of the range of the rollers 2 and the drive of the rollers 2 is switched on is. This happens so quickly that the billets stop temporarily I on the rollers 2 means no obstruction for the following blocks.
