Description

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Abtrennen und Abtransportieren ungekühlter und nicht toleranzhaltiger Drahtwindungen vom Anfang und Ende einer über eine Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems transportierten Walzader, wobei eine Anzahl vorderer Windungen der Walzader gezählt und nach Maßgabe einer vorgegebenen Zahl von Windungen diese vom Fertigdraht als Vorderschopfwindungen abgetrennt werden, die abgetrennten Vorderschopfwindungen beim Passieren einer offenen Weiche am Ende der ersten Transportstrecke aus der Ebene der Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems nach unten abgelenkt und abtransportiert werden, wogegen Fertigdraht nach Schließen der Weiche in der Stelmor-Anlage weitertransportiert wird.The invention relates to a method and a device for separating and Removing uncooled and non-tolerant wire windings from the beginning and end one over a Stelmor plant or a comparable wire winding transport system transported roll core, a number of front Number of turns of the rolling wire and according to a predetermined number from turns, these are separated from the finished wire as front crimp turns the cut front crimp turns when passing an open one Switch at the end of the first transport route from the level of the Stelmor facility or a comparable wire winding transport system is deflected downwards and transported away, whereas finished wire after closing the switch in the Stelmor plant is transported on.

Der Abmessungsbereich von Produkten moderner Drahtstraßen reicht von Drahtdurchmessem von 5,0 bis 25 mm mit einem Bereich von Endwalzgeschwindigkeiten zwischen 120 und ca. 20 m/s. Zur Einstellung der geforderten Gefügeeigenschaften sind Stelmor-Geschwindigkeiten bei der Abkühlung zwischen 0,1 m/s und ca. 1,2 m/s erforderlich. Nach der vom Durchmesser abhängigen Endwalzgeschwindigkeit ergeben sich dabei unterschiedliche Legedichten auf dem Stelmor-Transport oder vergleichbaren Drahtwindungs-Transportsystemen zwischen 25 und 300 Windungen pro Meter.The range of dimensions of modern wire rod products ranges from wire diameters from 5.0 to 25 mm with a range of finish rolling speeds between 120 and approx. 20 m / s. To set the required structural properties are Stelmor speeds when cooling between 0.1 m / s and approx. 1.2 m / s required. According to the final rolling speed depending on the diameter this results in different laying densities on the Stelmor transport or comparable wire winding transport systems between 25 and 300 turns per meter.

Bei dünnen Drahtabmessungen und hohen Endwalzgeschwindigkeiten bleiben aus Gründen der Störungssicherheit beim Walzen die Aderanfänge und -enden ungekühlt. Das Gleiche ist auch bei dicken Drahtabmessungen von beispielsweise 25 mm aus Gründen der sicheren Windungsablage der Fall. Zudem ist je nach Stichzahl im Fertigblock, beispielsweise bei 2 bis 10 Stichen, eine bestimmte Länge der Walzader am Anfang und Ende außerhalb der geforderten Abmessungstoleranzen. Infolgedessen müssen die ungekühlten und nicht toleranzhaltigen Windungen vor der Bundkompaktierung und Bindung entfernt werden.Stay with thin wire dimensions and high final rolling speeds for reasons of fault safety when rolling, the core starts and ends uncooled. The same is true for thick wire dimensions, for example 25 mm the case for reasons of safe winding storage. It also depends Number of stitches in the finished block, for example with 2 to 10 stitches, a certain length the roll core at the beginning and end outside the required dimensional tolerances. As a result, the uncooled and non-tolerant turns must removed before bundling and binding.

Beim Stand der Technik geschieht dies am Coilanfang an der Hakenbahn und zwar an der offenen Hakenseite. Am Coilende bereitet das Abtrennen größte Schwierigkeiten, weil hierfür bisher noch Handarbeit erforderlich ist und jede Windung einzeln durchtrennt und entfernt werden muss. Bei Temperaturen zwischen 400 und 500 °C ergeben sich für die dort beschäftigten Personen außerordentlich ungünstige und schwierige Arbeitsverhältnisse. Diese Arbeit ist einerseits personalintensiv und andererseits durch Hitze und schwere körperliche Arbeit belastet.In the prior art, this happens at the beginning of the coil on the hook track and on the open hook side. At the end of the coil, the separation is the biggest Difficulties because manual work has so far been required and every turn must be cut and removed individually. At temperatures between 400 and 500 ° C result extraordinarily for the people employed there unfavorable and difficult employment relationships. On the one hand, this work is personnel-intensive and on the other hand burdened by heat and heavy physical labor.

Um die Abtrennung (Schopfen) und Ausschleusung nicht toleranzhaltiger Drahtwindungen von einem Drahtwindungsstrang zu vereinfachen, wird in der DE 40 35 192 A1 folgende Vorrichtung vorgeschlagen. Einer ersten Rollenbahn ist ein Schopfschacht mit Fangarmen nachgeordnet, in dem die zu schopfenden Drahtwindungen durch eine Schere abgetrennt werden. Die Steuerung der Schere und des Einfallens der Fangarme in den Schopfschacht erfolgt durch einen Prozessleitrechner mit Bilderkennungsrechner, der mit einem oberhalb der Rollenbahn angeordneten opto-elektronischen Sensor verbunden ist. Unterhalb des Schopfschachtes ist eine über einen Hydraulikzylinder bewegbare zweite Rollenbahn angeordnet, die aus der Transportrichtung heraus gekippt werden kann und zu entfernende Drahtwindungen nach unten aus dem Drahtwindungsstrang herausfördert. Alternativ greift zur Ausschleusung der abgetrennten Drahtwindungen eine umlaufende, als Parallelogramm schwenkbare, Kette von unten durch eine Lücke in der Rollenbahn, die in diesem Eingreifbereich zweigeteilt ausgeführt, und transportiert die Drahtwindungen entgegen der Drahtwindungsstrang-Transportrichtung in einen Schrottkübel.The separation (cropping) and removal of non-tolerant wire windings To simplify a wire winding strand is described in DE 40 35 192 A1 proposed the following device. A first roller conveyor is one Downstream shaft with tentacles arranged in which the wire turns to be cropped be separated with scissors. The control of the scissors and The falling of the tentacles into the crest shaft is carried out by a process control computer with image recognition computer, which with one above the roller conveyor arranged opto-electronic sensor is connected. Below the crest shaft a second roller conveyor which is movable via a hydraulic cylinder is arranged, that can be tilted out of the transport direction and those to be removed Conveys wire turns downwards out of the wire turn strand. Alternatively, one intervenes to remove the separated wire windings circumferential chain, pivotable as a parallelogram, from below through a gap in the roller conveyor, which is carried out in two parts in this engagement area, and transported the wire windings against the wire winding strand transport direction in a scrap bucket.

Der Erfindung liegt die Aufgabe zugrunde, ausgehend vom vorgenannten Stand der Technik ein Verfahren und eine Vorrichtung anzugeben, mit deren Hilfe der erforderliche handwerkliche Einsatz beim Abtrennen ungekühlter und nicht toleranzhaltiger Drahtwindungen vom Anfang und Ende einer über eine Stelmor-Anlage oder vergleichbare Drahtwindungs-Transportsysteme transportierten Walzader durch eine noch zuverlässigere Mechanisierung bzw. Automatisierung ersetzt werden kann, um damit humanere Arbeitsbedingungen und wirtschaftlichere Abläufe zu schaffen.The invention is based on the object, starting from the aforementioned state state of the art to specify a method and a device with the aid of which required manual work when cutting uncooled and non-tolerant Wire windings from the beginning and end of one over a Stelmor system or comparable wire winding transport systems Rolling wire through an even more reliable mechanization or automation can be replaced to create more humane working conditions and more economical Create processes.

Zur Lösung dieser Aufgabe wird bei einem Verfahren zum Abtrennen und Abtransportieren ungekühlter und nicht toleranzhaltiger Drahtwindungen vom Anfang und Ende einer über eine Stelmor-Anlage oder vergleichbare Drahtwindungs-Transportsysteme transportierten Walzader eine Folge von Arbeitsschritten entsprechend den Merkmalen von Anspruch 1 vorgeschlagen.To solve this problem, a method for separating and removing uncooled and non-tolerant wire turns from the beginning and end one over a Stelmor plant or comparable wire winding transport systems corresponding to a series of work steps proposed the features of claim 1.

Dabei wird zunächst eine Anzahl vorderer Windungen der Walzader gezählt und nach Maßgabe einer vorgegebenen.Zahl von Windungen werden diese als Vorderschopf vom Fertigdraht abgetrennt. Anschließend werden die abgetrennten Windungen auf einer ersten Transportstrecke beschleunigt und der folgende Fertigdraht verzögert und damit die Schnittstelle im Transport verbreitert. Sodann werden die abgetrennten Vorderschopfwindungen beim Passieren einer zunächst offenen Weiche am Ende der ersten Transportstrecke aus der Ebene der Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems nach unten abgelenkt und abtransportiert, wogegen Fertigdraht nach Schließen der Weiche in der Stelmor-Anlage weiter transportiert und die abgetrennten und abtransportierten Windungen unter der Stelmor-Anlage auf einem Dom als Minibunde gesammelt oder einer Häckselschere zugefördert und darin zerhäckselt werden.First, a number of front turns of the rolling core are counted and according to a given number of turns, these are called the front cropping separated from the finished wire. Then the separated ones Coils accelerate on a first transport route and the following finished wire delayed and thus broadened the interface in transport. thereupon the separated front crimp turns when passing one initially open switch at the end of the first transport route from the level of the Stelmor facility or a comparable wire winding transport system downwards distracted and transported away, whereas finished wire after closing the switch in the Stelmor system and the separated and transported away Windings collected under the Stelmor system on a cathedral as mini bundles or chopped shears and chopped up.

Zum Abtrennen und Abtransportieren der Hinterschopfwindungen wird erfindungsgemäß ähnlich vorgegangen. Dabei wird das hintere Ende der Walzader überwacht und nach Erreichen einer vorgegebenen Restlänge diese von der Walzader als Hinterschopf abgetrennt, und der restliche, vom Hinterschopf getrennte Fertigdraht im Transport beschleunigt, zugleich werden die abgetrennten Hinterschopfwindungen auf der ersten Transportstrecke verzögert und damit die Schnittstelle verbreitert, und schließlich werden die abgetrennten Hinterschopfwindungen beim Einfahren in die offene Weiche am Ende der ersten Transportstrecke aus der Ebene der Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems nach unten abgelenkt und abtransportiert, unter der Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems gesammelt und zerteilt.In order to separate and remove the crescent hair turns, the invention is based proceeded similarly. The rear end of the roller core is monitored and after reaching a predetermined remaining length from the roll core severed as a crotch, and the rest of the finished wire separated from the crest accelerated in transport, at the same time the separated crimp turns delayed on the first transport route and thus the interface widened, and finally the separated crescent turns at Enter the open switch at the end of the first transport route from the plain the Stelmor plant or a comparable one Wire winding transport system deflected down and transported away, under the Stelmor plant or one comparable wire winding transport system and divided.

Mit großem Vorteil wird durch das erfindungsgemäße Verfahren das Abtrennen ungekühlter und nicht toleranzhaltiger Drahtwindungen vom Bund am Haken der Hakenbahn in den Transportbereich der Stelmor-Anlage verlagert oder eines vergleichbaren Drahtwindungs-Transportsystems. Damit entfällt der bisher erforderliche personelle Einsatz, wodurch zugleich die Wirtschaftlichkeit des Verfahrens erheblich verbessert wird.The process according to the invention is of great advantage the separation of uncooled and non-tolerant Wire turns from the collar on the hook of the hook track into the Transport area of the Stelmor plant relocated or one comparable wire winding transport system. This eliminates the previously required human resources, which at the same time significantly improves the economics of the process becomes.

Bevorzugt kann dabei von der Maßnahme Gebrauch gemacht sein, dass aus den Vorderschopf- oder den Hinterschopfwindungen nach Passieren der Weiche unterhalb der Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems Minibunde beispielsweise auf einem Sammeldorn gebildet und diese abtransportiert und zur weiteren Verarbeitung gesammelt werden.The measure can preferably be used, that from the front or back crotch turns Pass the switch below the Stelmor system or one comparable wire winding transport system mini bundles for example, formed on a mandrel and this removed and collected for further processing become.

Eine Ausgestaltung des Verfahrens sieht vor, dass die als Weiche ausgebildete erste Transportstrecke zum öffnen aus der Ebene einer Stelmor-Anlage oder eines vergleichbaren Drahtwindungs-Transportsystems schräg/abwärts abklappbar und zum Schließen in die Transportebene hochklappbar ist bzw. dass das nachfolgende Segment zum öffnen aus der Transport-Ebene schräg-aufwärts geklappt und zum Schließen in die Transport-Ebene heruntergeklappt wird. Alternativ kann aber auch von der Maßnahme Gebrauch gemacht sein, dass als Weiche ausgebildete, zu den Seiten quer zur Transportrichtung verschiebbare Stummelrollen zum öffnen auseinanderfahrbar und zum Schließen wieder zusammenfahrbar sind.An embodiment of the method provides that the as Soft trained first transport route to open from the Level of a Stelmor plant or a comparable one Wire winding transport system can be folded down and down can be folded up into the transport level for closing or that the following segment can be opened from the Transport level folded diagonally upwards and to close in the transport level is folded down. Alternatively, you can but also be made use of the measure that as Soft trained, to the sides across the direction of transport sliding stub rollers can be opened and opened can be moved together again to close.

Weiterhin sieht eine Ausgestaltung der Erfindung vor, dass die Weiche zum Abführen von Vorderschopfwindungen beim Trennschnitt geöffnet und unmittelbar vor Eintreffen der Schnittstelle am Ende der ersten Transportstrecke geschlossen wird, wobei der Fertigdraht nach Abtrennen und Abführen des Vorderschopfes über die SteLmor-AnLage oder eines vergleichbaren Drahtwindungs-Transportsystems transportiert wird.Furthermore, an embodiment of the invention provides that the Switch for removing front crimp turns at Separation cut opened and immediately before the arrival of the Interface closed at the end of the first transport route is, the finished wire after disconnection and removal of the Front head over the SteLmor plant or one comparable wire winding transport system transported becomes.

Und schließlich sieht das erfindungsgemäße Verfahren vor, dass das Abtrennen der Hinterschopfwindungen in dem Moment vorgenommen wird, in dem das optisch oder magnetisch überwachte hintere Ende der Walzader eine vorherbestimmte Position beispielsweise im Bereich des Drahtfertigblockes erreicht hat.And finally, the method according to the invention provides that cutting off the crescent crimp at that moment is made in which the optical or magnetic monitored rear end of the rolling wire a predetermined Position, for example, in the area of the wire finishing block has reached.

Dem Windungsleger (12) ist eine Schere (13) nachgeordnet oder auch vorgeschaltet, die bei Ingangsetzen an einer Schnittstelle (3) die Walzader (20) in einen Vorderschopf (30') und Fertigdraht (30) trennt. Die an die Weiche (4) anschließende Stelmor-Anlage (1) oder eines vergleichbaren Drahtwindungs-Transportsystems transportiert den vom Vorderschopf (30') abgetrennten Fertigdraht (30) in bekannter Weise gemäß Fig. 3 über eine Längere Kühlstrecke der Stelmor-Anlage (1). Oberhalb der ersten Transportstrecke (2) befindet sich eine optische oder magnetische Zähleinrichtung (14), welche eine vorgegebene Anzahl von Vorderschopfwindungen (30') zählt und nach Maßgabe einer vorgegebenen Zahl dieser Windungen (30') einen Aktionsbefehl an die Schere (13) überträgt, die dann an der Schnittstelle (3) die Trennung von Vorderschopf (30') und Fertigdraht (30) durchführt.A scissors (13) is arranged downstream of the winding layer (12) or also upstream, which when starting on a Interface (3) the roll core (20) in a front head (30 ') and finished wire (30) separates. The to the switch (4) subsequent Stelmor plant (1) or a comparable one Wire winding transport system transports the from Front head (30 ') separated finished wire (30) in a known 3 over a longer cooling section of the Stelmor plant (1). Above the first transport route (2) there is an optical or magnetic counter (14), which has a predetermined number of front crimp turns (30 ') counts and according to a predetermined number of these Turns (30 ') an action command to the scissors (13) transmits, which then at the interface (3) the separation of Front head (30 ') and finished wire (30).

Wie Figur 2 dazu zeigt, kontrolliert die Zähleinrichtung (14) weiterhin die Schnittstelle (3) und übermittelt nach Verlauf z. B. einer vorberechneten Zeitspanne an die Hubeinrichtung (19) einen Schließbefehl. Dabei ist eine vorgegebene Zeitverzögerung so berechnet, dass die Weiche (4) unmittelbar nach Verlassen der Letzten Vorderschopfwindung (30') und vor Eintreffen der ersten Windung vom Fertigdraht (30) geschlossen wird. Um hierfür etwas zeitlichen Spielraum zu schaffen, werden die abgetrennten Vorderschopfwindungen (30') auf der begrenzten ersten Transportstrecke (2) beschleunigt und der davon getrennte Fertigdraht (30) verzögert, womit die Schnittstelle (3) im Transport verbreitert wird. Dabei zeigt Fig. 2, dass die abgetrennten Vorderschopfwindungen (30') beim Passieren der offenen Weiche (4) am Ende der Transportstrecke (2) aus der Ebene der Stelmor-Anlage (1) oder eines vergleichbaren Drahtwindungs-Transportsystems nach unten abgelenkt und abtransportiert werden, wogegen gemäß Figur 3 nach Schließen der Weiche (4) mit dem Hubaggregat (19) der Fertigdraht (30) in der Stelmor-Anlage (1) oder eines vergleichbaren Drahtwindungs-Transportsystems weitertransportiert wird. Die gemäß Fig. 2 über die anfänglich noch offene Weiche (4) nach unten abtransportierten Vorderschopfwindungen (30') können dort beispielsweise auf einem Dorn (18) als Minibunde gesammelt oder mit Hilfe eines Treibers einer Häckselschere zugefördert und darin zerhäckselt werden. Dieser Teil der Anlage ist dem Fachmann bekannt und daher nicht dargestellt.As FIG. 2 shows, the counter device (14) controls continues the interface (3) and transmits according to the course z. B. a pre-calculated period of time to the lifting device (19) a close command. There is a given one Time delay calculated so that the switch (4) immediately after leaving the last front crimp turn (30 ') and before Arrival of the first turn of the finished wire (30) closed becomes. In order to create some scope for this, the separated front crimp turns (30 ') on the limited first transport route (2) accelerated and the finished wire (30) separated therefrom, with which the Interface (3) is widened in transport. It shows Fig. 2 that the cut front windings (30 ') at Pass the open switch (4) at the end of the transport route (2) from the level of the Stelmor plant (1) or one comparable wire winding transport system down are deflected and transported away, whereas according to FIG. 3 after closing the switch (4) with the lifting unit (19) Finished wire (30) in the Stelmor system (1) or one comparable wire winding transport system is transported further. 2 over the initial the open switch (4) was transported downwards Forefold windings (30 ') can be found there, for example a thorn (18) collected as a mini bundle or with the help of a Driver a chopper scissors conveyed and chopped therein become. This part of the system is known to the person skilled in the art and therefore not shown.

Wie die Figuren 1 bis 5 in Zusammenschau zeigen, überwacht die Kontrolleinrichtung (15) mit Hilfe elektronischer oder magnetischer Erfassungsmittel die Walzader (20) und löst ein Signal aus, sobald Anfang oder Ende eine vorgegebene Position vor oder innerhalb des Draht-Fertigblocks (10) erreicht haben. Dieses Signal wird mit der Signalleitung (21, Fig. 4) auf die Schere (13) übertragen, die dann nach Maßgabe einer vorgegebenen Länge des Endes der Walzader (20) dieses vom übrigen Fertigdraht (30) abtrennt und zwar an einer Trennstelle (3), wie dies in Fig. 4 dargestellt ist. Danach übernimmt die Kontrolleinrichtung (14) die Kontrolle der wandernden Schnittstelle (3) und veranlasst nach vorgegebener Verzögerungszeit die Hubeinrichtung (19) zum Absenken der ersten Transportstrecke (2), d. h. zum öffnen der Weiche (4). Das dann bereits vorgelaufene Stück Fertigdraht (30) der Walzader läuft über die Kühlstrecke der Stelmor-Anlage (1), während die Hinterschopfwindungen (30'') beim Einlaufen in die Weiche (4) nach unten abgelenkt und auf dem Dorn (18) in bereits vorbeschriebener Weise in Minibunden gesammelt oder beispielsweise zu Schrott zerhäckselt werden.As FIGS. 1 to 5 show together, the Control device (15) using electronic or magnetic detection means the roller core (20) and redeems Signal off as soon as the beginning or end of a predetermined position have reached before or within the wire finishing block (10). This signal is connected to the signal line (21, Fig. 4) Transfer scissors (13), which then according to a predetermined length of the end of the roller core (20) this from separates the remaining finished wire (30) on one Separation point (3), as shown in Fig. 4. After that the control device (14) takes control of the migrating interface (3) and initiates according to predetermined Delay time the lifting device (19) for lowering the first transport route (2), d. H. to open the switch (4). The piece of finished wire (30) that has already preceded the Rolling wire runs over the cooling section of the Stelmor plant (1), while the crimp turns (30 '') when entering the Switch (4) deflected downwards and on the mandrel (18) already collected in mini bundles as described above or for example, be shredded into scrap.

Figur 4 zeigt die Vorrichtung im Moment eines Betriebszustandes, bei dem die Kontrolleinrichtung (15) das Ende der Walzader (20) erfasst und ein Signal mit der Signalleitung (21) zur Aktivierung der Schere (13) auslöst. Diese trennt augenblicklich die Walzader bzw. den Fertigdraht (30) an der Schnittstelle (3) in Fertigdraht (30) und eine in Hinterschopfwindungen (30'') auszulegendes Reststück von vorgegebener Länge.Figure 4 shows the device at the moment Operating state in which the control device (15) End of the roller core (20) detected and a signal with the Triggers signal line (21) to activate the scissors (13). This instantly separates the rolled wire or the finished wire (30) at the interface (3) in finished wire (30) and one in The remaining part of given length.

Figur 5 zeigt die Vorrichtung im Moment eines Betriebszustandes, bei dem die Zähleinrichtung (14) die Schnittstelle (3) kurz vor dem Ende der Transportstrecke (2) erfasst und mit vorgegebener Verzögerung das öffnen der Weiche (4) durch Abklappen der Transportstrecke (2) mittels der Hubeinrichtung (19) veranlasst. Dadurch werden - gemäß Darstellung in der Figur 6 - die Hinterschopfwindungen (30") unter das Niveau der Stelmor-Anlage (1) oder eines vergleichbaren Drahtwindungs-Transportsystems abgelenkt, während der Fertigdraht (30) - nunmehr nach Abtrennen von Vorder (30')- und Hinterschopfwindungen (30") - über die Stelmor-Anlage (1) oder eines vergleichbaren Drahtwindungs-Transportsystems weitergefördert wird. Die Hinterschopfwindungen (30''), ebenso wie vorher gemäß Fig. 2 die Vorderschopfwindungen (30'), werden nach unten abgeleitet und fallweise auf dem Sammeldorn (18) zu Minibunden gesammelt oder in einer Häckselschere zu Schrottteilen zerkleinert.Figure 5 shows the device at the moment Operating state in which the counter (14) Interface (3) shortly before the end of the transport route (2) detected and with a predetermined delay opening the switch (4) by folding down the transport route (2) using the Lifting device (19) causes. This will - according to Representation in FIG. 6 - the cramp turns (30 ") below the level of the Stelmor facility (1) or one comparable wire winding transport system distracted, during the finished wire (30) - now after cutting off Front (30 ') - and Hinterschopfwindungen (30 ") - over the Stelmor plant (1) or a comparable one Wire winding transport system is promoted. The Hinterschopfwindungen (30 ''), as before according to FIG. 2 the front crimp turns (30 ') are derived downwards and occasionally collected on the collecting mandrel (18) into mini bundles or shredded into scrap parts in a chopper.
