Abstract

The invention relates to a device for introducing rolled steel sections piled up into layers after cooling beds into a cold shearing or straightening machine. In the device, the layers, which have been transferred to a roller table ahead of the straightening or shearing machine, are held by a correspondingly profiled hold-down roller, taken over by a holding device, which is suspended above the roller table, can be traversed in the longitudinal direction of the sections and is designed as a lifting magnet with profile strips, and are conveyed to the driver of the cold shearing or straightening machine synchronously with the transfer rate of the roller table. In order to provide a device for feeding the rolled steel sections into cold shearing or straightening machines which can be retrofitted into existing plants and guarantees reliable guidance of the layers of bar steel into the shearing and straightening machine, it is proposed that the hold-down roller (5) and the holding device (13) be arranged on a common carriage (3), that the lifting magnet (6) be displaceable parallel to the transfer path of the carriage (3) by a limited distance (14) relative to the holding device (13) and be provided with a displacement measuring device which, as a function of the displacement measured, outputs a signal to the drive (9) of the carriage (3) via a computer in order to match the carriage speed to the speed of the material. …<IMAGE>…

Description

Die Erfindung betrifft eine Vorrichtung zum Einführen von hinter Kühlbetten zu Lagen gesammelten Walzstahlprofilen in eine Kaltschere oder Richtmaschine, bei der die auf einen Rollgang vor der Richtmaschine oder Schere transportierten Profillagen von einer profilierten Niederhalterolle gehalten, von einer in Profillängsrichtung hängend oberhalb des Rollganges verfahrbaren, als Hubmagnet mit Profilleisten ausgebildeten Haltevorrichtung übernommen und synchron zur Transportgeschwindigkeit des Rollganges zum Treiber der Kaltschere oder Richtmaschine transportiert werden.The invention relates to a device for inserting rolled steel profiles collected in layers behind cooling beds into a cold shear or straightening machine, in which the profile layers transported on a roller table in front of the straightening machine or scissors are held by a profiled hold-down roller, movable from a hanging in the longitudinal direction of the profile above the roller table, as Lifting magnet with profile strips designed holding device are taken over and transported synchronously to the transport speed of the roller table to the driver of the cold shears or leveling machine.

Es wird zunehmens von den Betreibern gefordert, die hinter Kühlbetten zu Schneid- oder Richtlagen gesammelten Stabpakete nach dem Vorsammeln auf Scherenmesser bzw. Richtrollenteilung automatisch in die Kaltscheren bzw. Richtmaschinen einzufädeln. Eine gattungsgemäße Anlage ist durch die DE 38 18 745 A1. Figur 7. beschrieben.Increasingly, operators are required to automatically thread the bundles of bars collected behind cooling beds into cutting or straightening positions after they have been pre-collected on the scissor knife or straightening roller division into the cold shears or straightening machines. A generic system is by DE 38 18 745 A1. Figure 7.

Wird die Eihfädelvorrichtung der gattungsgemäßen Art nicht in Verbindung mit den vorgeschalteten Einrichtungen zum Halten der Stäbe während des gesamten Abkühlvorganges eindesetzt, sondern beispielsweise in bestehende Adjustageanlagen nachträglich eingeführt, so besteht weiterhin das Problem, ungerade Stabpakete so zu legen, daß ein ordnungsdemäße Übernahme durch den Hubmagneten möglich ist und das Einführen in die Schere bzw. die Richtmaschine gewährleistet ist. Auch muß sichergestellt sein, daß beim Transport der Stäbe die Geschwindigkeit von dem die Stabenden haltenden Hubmagnet und des Rollganges so aufeinander abgestimmt sind, daß die Stäbe nicht gegenüber dem Magnet durch Reibung an den Rollgangsrollen beschleunigt oder verzögert werden. Dies würde dazu führen, daß die Stäbe sich zueinander verschieben oder abfallen.If the egg threading device of the generic type is not used in connection with the upstream devices for holding the rods during the entire cooling process, but is subsequently introduced, for example, into existing finishing systems, then there is still the problem of placing odd rod packages in such a way that they are properly taken over by the lifting magnet is possible and the introduction into the scissors or the straightening machine is guaranteed. It must also be ensured that when the bars are transported, the speed of the lifting magnet holding the bar ends and the roller table are matched to one another in such a way that the bars are not accelerated or decelerated relative to the magnet by friction on the roller table rollers. This would cause the bars to shift or fall apart.

Aufgabe der vorliegenden Erfindung ist es. eine Vorrichtung zum Einführen der Walzstahlprofile in Kaltscheren oder Richtmaschinen zu schaffen, die nachträglich in bestehende Anlagen eingebaut werden kann und die eine sichere Führung der Stabstahllagen in Schere und Richtmaschine gewährleistet.The object of the present invention is. to create a device for inserting the rolled steel profiles in cold shears or straightening machines, which can be retrofitted into existing systems and which ensures a safe guidance of the steel bar layers in the shears and straightening machine.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, daß die Niederhalterolle und die Haltevorrichtung an einem demeinsamen Wagen angeordnet sind, daß der Hubmagnet gegenüber der Haltevorrichtung um einen begrenzten Weg barallel zum Transportweg des Wagens verschiebbar ist und mit einer Wegmeßeinrichtung versehen ist, die über einen Rechner in Abhängigkeit vom gemessenen Weg ein Signal an den Antrieb des Wagens zur Anpassund der Wadengeschwindidkeit an die Materialgeschwindigkeit abgibt.To achieve the object, it is proposed according to the invention that the hold-down roller and the holding device are arranged on a common carriage, that the lifting magnet can be displaced relative to the holding device by a limited distance, parallel to the transport path of the carriage, and is provided with a displacement measuring device which is controlled by a computer Depends on the measured distance a signal to the drive of the car for adjustment and the calf speed to the material speed.

Der Vorteil des erfindungsgemäßen Vorschlages ist darin zu sehen, daß auch unsymetrische Profile, wie zum Beispiel Winkel. die bekanntermaßen an ihren Enden nach dem Abkühlvorgang hochstehen (Ski-Effekt) durch die am Wagen angeorgnete profilierte Niederhalterolle beim Verfahren des Wagens in die erforderliche Lage gebracht werden und daß die Niederhalterolle vor dem Aufsetzen der Magnete die Profile niederdrücken kann. Des weiteren wird sichergestellt, daß die Geschwindigkeit der Stablage jeweils der Geschwindigkeit des am Wagen bzw. an der Haltevorrichtung angeordneten Magneten übereinstimmt. indem der Magnet an der Haltevorrichtung verschiebbar ausgebildet ist und der Verschiebeweg als Maß und Signal für die Steuerung des Antriebs verwendet wird.The advantage of the proposal according to the invention can be seen in the fact that even asymmetrical profiles, such as angles. which are known to stand up at their ends after the cooling process (ski effect) by the profiled hold-down roller arranged on the carriage when the carriage is moved into the required position and that the hold-down roller can depress the profiles before the magnets are attached. Furthermore, it is ensured that the speed of the rod storage corresponds to the speed of the magnet arranged on the carriage or on the holding device. in that the magnet is designed to be displaceable on the holding device and the displacement path is used as a measure and signal for controlling the drive.

In einer günstigen Ausgestaltung der Erfindung ist vorgesehen, nach Loslassen der Stablage durch den Hubmagnet den Hubmagnet gegenüber der Haltevorrichtung in eine Verschiebe-Mittellage zu bringen, was beispielsweise durch Federn bewerkstelligt wergen kann. Durch die Verschiebbarkeit des Hubmagneten wird sicher ein Abreißen oder Verrutschen der Stäbe am Magneten verhindert.In a favorable embodiment of the invention it is provided, after the bar magnet has been released by the lifting magnet, to bring the lifting magnet into a shifting central position relative to the holding device, which can be accomplished, for example, by springs. The displaceability of the lifting magnet reliably prevents the bars from tearing off or slipping on the magnet.

Die vorliegende Erfindung wird anhand eines Ausführungsbeispiels nachfolgend beschrieben. Es zeigt:

  • Fig. 1 die erfindundsgemäße Vorrichtung in einer Seitenansicht nach Ablage der Walzstahlprofile,
  • Fig. 2 eine Ansicht gemäß Figur 1. jedoch mit heruntergefahrener Niederhalterolle kurz vor Aufsetzen des Hubmagneten und
  • Fig. 3 die Haltevorrichtung mit dem Hubmagneten in vergrößerter Darstellung.
The present invention is described below using an exemplary embodiment. It shows:
  • 1 shows the device according to the invention in a side view after storage of the rolled steel profiles,
  • 2 shows a view according to FIG. 1, but with the hold-down roller shut down shortly before the lifting magnet and
  • Fig. 3, the holding device with the solenoid in an enlarged view.

Die Einrichtung wird nunmehr anhand ihrer Funktionsweise beschrieben:The device will now be described in terms of how it works:

Nach Auflegen einer gesammelten Walzstahlprofillage 1 auf den Richt-oder Schneidrollgang 2 fährt der Wagen 3, an dem sowohl der Hubmagnet 6 an der Haltevorrichtung 13 als auch die profilierte Niederhalterolle 5 angeordnet sind, von seiner Warteposition über die Stabköpfe 4 hinweg in den Kühlbettbereich bis hinter den Beginn der Stabkrümmung. Dort wird die profilierte Rolle 5 auf die Walzstahlprofile 1 abgesenkt und der Wagen 3 verfährt in Richtung Stabanfang 4. Hochstehende oder horizontal gekrümmte Stäbe werden somit auf den vorgegebenen Abstand debracht und gleichzeitig heruntergedrückt.After placing a collected rolled steel profile layer 1 on the straightening or cutting roller table 2, the carriage 3, on which both the lifting magnet 6 on the holding device 13 and the profiled hold-down roller 5 are arranged, travels from its waiting position over the rod heads 4 into the cooling bed area and behind the beginning of the curvature of the rod. There, the profiled roller 5 is lowered onto the rolled steel profiles 1 and the carriage 3 moves in the direction of the start of the bar 4. Elevated or horizontally curved bars are thus brought to the specified distance and pressed down at the same time.

Befindet sich der Magnet 6 so über dem Stabpaket, daß ein zum Einfädeln nötiger Überstand in Transportrichtung erreicht ist, wird der Wagen 3 abgeschaltet, der Magnet 6 mit den Profilleisten 7 abgesenkt, bis er auf den Stäben zu liegen kommt und einschaltet (Figur 2).If the magnet 6 is located above the rod assembly in such a way that a protrusion in the direction of transport necessary for threading is reached, the carriage 3 is switched off, the magnet 6 with the profiled strips 7 is lowered until it comes to rest on the rods and switches on (FIG. 2) .

Die profilierte Rolle 5 wird sodann in die obere Position gefahren und anschließend hebt der Magnet die Stabköpfe um ca. 10 bis 20 mm vom Rollgang ab.The profiled roller 5 is then moved into the upper position and then the magnet lifts the rod heads from the roller table by about 10 to 20 mm.

Mit dem Anlaufen des Rollgangs in Richtung Richtmaschine bzw. Schere 8 wird gleichzeitid der Antrieb 9 des Wagens 3 eingeschaltet. Die Beschleunidung des Wagens 3 wird elektrisch so vorgegeben, wie die theoretische Materialbeschleunigung durch den Rollgang 2 erwartet wird. Beschleunigung und Verzögerung wird bestimmt durch den Reibfaktor zhischen Rolle und Stabmaterial.With the start of the roller table in the direction of the straightening machine or scissors 8, the drive 9 of the carriage 3 is simultaneously switched on. The acceleration of the carriage 3 is specified electrically as the theoretical material acceleration through the roller table 2 is expected. Acceleration and deceleration are determined by the friction factor between the roll and the bar material.

Der Madget 6 mit den auswechselbaren Profilleisten ist am Wagen 3 in und gegen Transportrichtung auf einer Bahn 14 verschiebbar angeordnet, so daß bei Geschwindigkeitsunterschieden über eine elektrische Wegmeßeinrichtung 10 der Fahrantrieb des Wagens der Materialgeschwindigkeit ständig angepaßt wird (Figur 3). Die elektrische Regelung ist so konzipiert, daß der Magnet ständig die Mittel- oder Null-Position der Gleichlaufregelung anstrebt. Im unbelasteten Zustand sorgen Rückstellfedern 11 oder Zylinder dafür, daß der Magnet sich immer in Null-Position befindet. Der Wagen mit dem eingeschalteten Magnet 6 führt die Stabköpfe 4 in die Schere 8 oder einen Treiber 12 ein, löst nach übergabe den Magneten 6 und fährt mit angehobenem Magneten in seine Parkposition vor dem Kühlbett zurück.The Madget 6 with the interchangeable profile strips is arranged on the carriage 3 so as to be displaceable in and against the direction of transport on a track 14, so that in the event of speed differences, the travel drive of the carriage is constantly adapted to the material speed by means of an electrical path measuring device 10 (FIG. 3). The electrical control is designed so that the magnet constantly strives for the center or zero position of the synchronization control. In the unloaded state, return springs 11 or cylinders ensure that the magnet is always in the zero position. The carriage with the magnet 6 switched on introduces the rod heads 4 into the scissors 8 or a driver 12, releases the magnet 6 after transfer and moves back to its parking position in front of the cooling bed with the magnet raised.
