Description
Die vorliegende Erfindung betrifft eine Ablegevorrichtung zum Ablegen von Windungen aus Draht mit einer Drahtachse auf einem Transportband, insbesondere einem Stelmor-Transportband, mit einem rotierenden Windungsleger mit einer Austrittsöffnung, aus der heraus die Windungen in einer Ablegerichtung mit einer Ablegegeschwindigkeit an das Transportband abgegeben werden.The present invention relates to a depositing device for depositing turns made of wire with a wire axis on a conveyor belt, in particular a Stelmor conveyor belt, with a rotating coiler with one Exit opening, out of which the turns in a depositing direction with a Deposit speed are given to the conveyor belt.
Eine derartige Ablegevorrichtung ist bspw. aus der EP 0 432 531 A1 bekannt.Such a depositing device is known, for example, from EP 0 432 531 A1.
Aus der DE 26 52 958 ist eine Einrichtung zur Vorbereitung des Trennschnittes bei Walzdraht bekannt, bei der das aus einem Windungsleger auslaufende Walzgut über ein Transportband einer Separiereinheit zugeführt wird, in der über eine Schere eine bedarfsweise Trennung des Walzdrahts vorgenommen wird.DE 26 52 958 describes a device for preparing the separating cut Wire rod is known in which the rolling stock running out of a winding layer is fed via a conveyor belt to a separation unit, in which a If necessary, the wire rod is cut.
Aufgrund der Herstellungsverfahren von warmgewalztem, schlanken Walzgut, wie z. B. Walzdraht, treten im Walzgut inhärente Dimensionsfehler und andere fehlerhafte Stellen am Anfang und am Ende eines Walzstückes auf. Folglich müssen diese unbrauchbaren Anfangs- und Endstücke entfernt werden. Wegen der immer höher werdenden Walzgeschwindigkeiten von zum Teil mehr als 120 m/s ist es jedoch nicht mehr möglich, den Draht in der Walzader störungsfrei zu schneiden. Ferner fallen die vorderen Windungen auf die kalten Rollen des Stelmor-Transportbandes und kühlen dort schneller ab als die nachfolgenden Windungen. Due to the manufacturing process of hot rolled, slim rolling stock, such as z. B. wire rod, inherent dimensional errors and other faulty occur in the rolling stock Set up at the beginning and end of a rolled piece. Hence must these unusable start and end pieces are removed. Because of always it is higher rolling speeds of sometimes more than 120 m / s however, it is no longer possible to cut the wire in the roll core without interference. The front windings also fall onto the cold rollers of the Stelmor conveyor belt and cool down there faster than the subsequent turns.
Dadurch entstehen unzulässige Gefügeveränderungen bei den Anfangswindungen. Diese Windungen dürfen also erst nach dem Stelmor-Transportband abgeschnitten werden. Bei den Anfangswindungen ist dies auch problemlos möglich, da sie nach dem Wickeln des Drahtes zu einem Bund leicht zugänglich sind und folglich abgeschnitten und entfernt werden können. Die hinteren Windungen dagegen sind nur unter großen Problemen zugänglich. Es ergibt sich eine unsichere und unfallträchtige Betriebsweise und ein großer personeller Zeitaufwand.This creates inadmissible structural changes in the initial turns. These windings may therefore only be cut off after the Stelmor conveyor belt become. With the initial turns, this is also possible without any problems, since they are easily accessible after winding the wire into a bundle and consequently can be cut off and removed. The back turns, however are only accessible with major problems. The result is an uncertain one and accident-prone mode of operation and a large expenditure of personnel.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Ablegevorrichtung zu schaffen, welche die Nachteile des Standes der Technik beseitigt.The object of the present invention is to provide a storage device create which eliminates the disadvantages of the prior art.
Die Aufgabe wird dadurch gelöst, dass dem Windungsleger eine Schere mit einem festen und einem mittels eines Messerantriebs in einer Schneidrichtung mit einer Schneidgeschwindigkeit beweglichen Messer unmittelbar nachgeschaltet ist und dass dem beweglichen Messer ein Separierblech zum Trennen der windungslegerseitigen Schlechtwindungen von den transportbandseitigen Gutwindungen zugeordnet ist und dass das bewegliche Messer zusammen mit dem Separierblech auf Schnittgeschwindigkeit beschleunigt wird.The task is solved in that the winding layer is equipped with a pair of scissors fixed and one by means of a knife drive in a cutting direction with a Cutting speed movable knife is immediately downstream and that the movable knife has a separating plate for separating the coil side Bad winds associated with the good turns on the conveyor belt side is and that the movable knife together with the separating plate is accelerated to cutting speed.
Wenn die Schneidrichtung mit der Ablegerichtung einen von 90° verschiedenen Winkel bildet, so dass die Schneidgeschwindigkeit eine zur Ablegerichtung parallele Komponente aufweist, und die Schneidgeschwindigkeit und die Ablegegeschwindigkeit derart aufeinander abgestimmt sind, dass die zur Ablegerichtung parallele Komponente der Schneidgeschwindigkeit in etwa gleich der Ablegegeschwindigkeit ist, wird der Draht erst kurz vor Schnittbeginn von dem Separierblech berührt. Die guten Windungen werden daher nicht deformiert.If the cutting direction with the laying direction is different from 90 ° Forms an angle, so that the cutting speed is parallel to the depositing direction Has component, and the cutting speed and the depositing speed are matched to one another in such a way that the direction of deposit parallel component of the cutting speed approximately equal to the depositing speed the wire is only removed from the separating plate shortly before the cut begins touched. The good turns are therefore not deformed.
Das bewegliche Messer und das Separierblech können eine lineare Bewegung ausführen. Der konstruktive Aufbau ist jedoch besonders einfach, wenn sie eine rotatorische Bewegung ausführen. The movable knife and the separating plate can make a linear movement To run. The constructive structure is particularly simple, however, if one Carry out rotary motion.
Der Draht wird an der richtigen Stelle abgeschnitten, wenn dem Windungsleger ein Drahterfassungssensor zum Erfassen des Drahtendes vorgeschaltet ist und das Erfassen des Drahtendes durch den Drahterfassungssensor das Betätigen der Schere auslöst.The wire is cut in place when the turntable a wire detection sensor for detecting the wire end is connected upstream and sensing the wire end by the wire sensing sensor actuating the scissors triggers.
Die letzten noch dem Transportband zugeführten Windungen werden besonders sicher dann nicht deformiert, wenn der Draht derart geschnitten wird, dass das von der Schere aus gesehen transportbandseitige Schnittende des Drahtes ziehend auf dem Transportband befördert wird. Der derartiger Schnitt kann insbesondere dadurch erreicht werden, daß dem Windungsleger ein Winkelerfassungssensor zugeordnet ist und das Auslösen der Schere dann erfolgt, wenn der Windungsleger einen vorbestimmten Drehwinkel erreicht.The last turns still fed to the conveyor belt become special certainly not deformed if the wire is cut in such a way that the the scissors pulling the cut end of the wire from the conveyor belt is transported on the conveyor belt. Such a cut can in particular thereby be achieved that the winding layer an angle detection sensor is assigned and the scissors are released when the Winding layer reaches a predetermined angle of rotation.
Wenn das feste und bewegliche Messer derart angeordnet sind, daß die Schere den Draht entlang einer Schnittfläche schneidet, die mit der Drahtachse einen Schnittwinkel von mindestens 45° einschließt, ist der Betrieb der Schere besonders störungssicher.If the fixed and movable knife are arranged such that the scissors cut the wire along a cutting surface that is using the wire axis includes a cutting angle of at least 45 °, the operation of the scissors is particularly fail-safe.
Wenn die Austrittsöffnung und die Schere derart von einer Schutzhaube überdeckt sind, daß von der Schere aus gesehen windungslegerseitige Windungen innerhalb der Schutzhaube gehalten werden, können keine Windungen aus der Schutzhaube herausschleudern. Insbesondere Personengefährdungen werden hierdurch vermieden.If the outlet opening and the scissors so from a protective hood are covered that seen from the scissors on the turntable side Windings can be kept inside the protective hood do not throw any turns out of the protective hood. In particular In this way, personal hazards are avoided.

Gemäß den Fig. 1 bis 6 weist eine Ablegevorrichtung zum Ablegen von
Windungen aus Draht einen rotierenden Windungsleger 1 auf. Der
Windungsleger 1 weist eine Austrittsöffnung 2 auf, aus der heraus
ein Draht 3 in Windungen in einer Ablegerichtung 4 mit einer Ablegegeschwindigkeit
vA an ein Transportband 5 abgegeben wird. Die
Ablegegeschwindigkeit vA ist dabei die Geschwindigkeit, mit der sich
die Drahtwindungen entlang ihrer Windungsachse bewegen. Das Transportband
5 ist im vorliegenden Fall als sogenanntes Stelmor-Transportband
5 ausgebildet.According to FIGS. 1 to 6, a depositing device for depositing windings made of wire has a rotating
Um den Draht 3 nach dem Austreten aus der Austrittsöffnung 2 abschneiden
zu können, ist dem Windungsleger 1 eine Schere 6 nachgeschaltet.
Die Schere 6 weist ein festes Messer 7 und ein bewegliches
Messer 8 auf. Die Schere 6 wird von einem Messerantrieb 9
angetrieben und schneidet den Draht 3 in einer Schneidrichtung 10
mit einer Schneidgeschwindigkeit vS.In order to be able to cut the
Wie insbesondere aus den Fig. 1, 5 und 6 ersichtlich ist, bildet
die Schneidrichtung 10 mit der Ablegerichtung 4 einen Winkel α, der
von 90° verschieden ist. Die Schneidgeschwindigkeit vS hat daher
eine Komponente vSA parallel zur Ablegerichtung. Die Schneidgeschwindigkeit
vS und die Ablegegeschwindigkeit vA sind derart
aufeinander abgestimmt, daß die zur Ablegerichtung 4 parallele Komponente
vSA der Schneidgeschwindigkeit vS zwischen 75 und 125 %,
vorzugsweise zwischen 90 und 110 %, der Ablegegeschwindigkeit vA
beträgt.As can be seen in particular from FIGS. 1, 5 and 6, the cutting
Der Messerantrieb 9 ist im vorliegenden Fall als Elektromotor
ausgebildet. Er könnte aber auch als Hydraulikmotor, als Hydraulikzylindereinheit
oder als Pneumatikzylindereinheit ausgebildet sein. The
Dem beweglichen Messer 8 ist zum Trennen des Windungslegers 1 vom
Transportband 5 ein Separierblech 11 zugeordnet. Das Separierblech
11 ist dabei als Platte ausgebildet, die im wesentlichen parallel
zur Schneidrichtung 10 verläuft.The
Um das Schneiden des Drahtes 3 zum richtigen Zeitpunkt auszulösen,
ist dem Windungsleger 1 ein Drahterfassungssensor 12 vorgeschaltet.
Durch den Drahterfassungssensor 12 wird das Ende des Drahtes 3
erfaßt, welches dann - gegebenenfalls über ein Zeitglied - das
Betätigen der Schere 6 auslöst. Der Drahterfassungssensor 12 kann
bspw. als Fotozelle ausgebildet sein.In order to start cutting the
Wie insbesondere aus Fig. 4 ersichtlich ist, führen das bewegliche
Messer 8 und das Separierblech 11 eine rotatorische Bewegung aus.
Wegen der großen dabei zu beschleunigenden und zu verzögernden
trägen Massen sind daher erhebliche Beschleunigungs- und Verzögerungswege
erforderlich.As can be seen in particular from FIG. 4, the
Zum Schneiden des Drahtes 3 wird das bewegliche Messer 8 zusammen
mit dem Separierblech 11 vom Messerantrieb 9 aus der in Fig. 3
dargestellten Anfangsstellung auf die Schneidgeschwindigkeit vS
beschleunigt. Danach wird der Draht 3 in der in Fig. 4 dargestellten
Stellung geschnitten und sodann das bewegliche Messer 8 zusammen
mit dem Separierblech 11 abgebremst. Das bewegliche Messer 8 und
das Separierblech 11 kommen dann in der in Fig. 4 gestrichelt
dargestellten Stellung zum Stehen. Sie werden dann wieder in die
Stellung gemäß Fig. 3 gedreht, um für den nächsten Schnitt vorbereitet
zu sein.To cut the
Der Transport der Windungen des Drahtes 3 auf dem Transportband 5
ist besonders störungssicher, wenn der Draht 3 derart geschnitten
wird, daß das von der Schere 6 aus gesehen transportbandseitige
Schnittende 13 des Drahtes 3 ziehend auf dem Transportband 5 befördert
wird. Ein derartiger Schnitt ist beispielhaft in Fig. 7 dargestellt.
Ein derartiger Schnitt kann dadurch erreicht werden, daß dem Windungsleger
1 ein Winkelerfassungssensor 14 zugeordnet ist, mittels
dessen die Winkelposition der Austrittsöffnung 2 erfaßt werden kann.
Das Auslösen der Schere 6 erfolgt in diesem Fall nur dann, wenn der
Windungsleger 1 bzw. die Austrittsöffnung 2 einen vorbestimmten
Drehwinkel erreichen. Der Drehwinkel ist dabei selbstverständlich
nur modulo 2π bestimmt. Dabei ist Drehwinkel als solcher beliebig
wählbar, da der Beginn der Beschleunigung des beweglichen Messers
8 gegebenenfalls noch von einem Zeitglied verzögert werden kann.
Entscheidend ist, daß beim Beginn des Beschleunigungsvorgangs der
Windungsleger 1 eine definierte Winkellage erreicht. Der Winkelerfassungssensor
kann bspw. als Magnetsensor ausgebildet sein, der
von einem Eisenplättchen ausgelöst wird, welches zusammen mit dem
Windungsleger rotiert.The transport of the turns of the
Üblicherweise werden die letzten 3 bis 10 Windungen des Drahtes 3
abgeschnitten. Um zu verhindern, daß die unbrauchbaren abgeschnittenen
letzten Windungen des Drahtes 3 undefiniert aus der Austrittsöffnung
2 austreten und insbesondere aus der Ablegevorrichtung
herausgeschleudert werden, sind die Austrittsöffnung 2 und die
Schere 3 von einer Schutzhaube 15 überdeckt. Der Abstand des vorderen
Endes der Schutzhaube 15 vom beweglichen Messer 8 nebst
Separierblech 11 ist dabei derart gering, daß die Windungen des
Drahtes 3, die von der Schere 6 aus gesehen windungslegerseitig
gelegen sind, innerhalb der Schutzhaube 15 gehalten werden.Usually the last 3 to 10 turns of
Das feste Messer 7 und das bewegliche Messer 8 sind gemäß Ausführungsbeispiel
in einem Winkel zur mit 16 bezeichneten Ebene angeordnet.
Dadurch wird erreicht, daß die Schere 6 den Draht 3 entlang
einer Schnittfläche schneidet, die mit der Drahtachse einen Schnittwinkel
von mindestens 45° einschließt. Der Schnittwinkel ist vorzugsweise
größer als 45°, z.B. mindestens 60°. Optimal ist ein
völlig senkrechter Schnitt, also ein Schnittwinkel von 90°. Ein
derartiger Schnitt wird dadurch erreicht, daß die Schneidkanten der
Messer 7, 8 in etwa parallel zur Ablegerichtung 4 ausgerichtet sind. The fixed
Die abgeschnittenen Drahtwindungen fallen aufgrund der Schwerkraft
in einen Auffangbehälter 17, der unterhalb der Schere 6 angeordnet
ist. Um die abgeschnittenen Endwindungen des Drahtes 3 leicht
handhaben zu können, ist zwischen der Schere 6 und dem Auffangbehälter
17 ein nicht dargestellter Drahtzerkleinerer angeordnet. Der
Drahtzerkleinerer kann bspw. als Häckselschere bekannter Bauart mit
schraubenförmigen Messern ausgebildet sein.The cut wire turns fall due to gravity

Das bewegliche Messer 8 wird von dem Separierblech 11 gehalten,
das über eine Welle 19 in einem Gehäuse 20 gelagert ist. Die
Welle 19 ist über eine Kupplung 21 und ein Getriebe 22 mit dem
Messerantrieb 9 verbunden. Die Schutzhaube 15 deckt den eigentlichen
