Zur Herstellung von Leiterbahnen für Flachbandkabel unterschiedlicher Breite und Dicke wird zumeist zum Coil gewickeltes Blechband in Längsteilanlagen (Scheren) in mehrere Bandstreifen geteilt. Das Trennen erfolgt durch verlustfreies (spanloses) Schneiden mit Kreismessern. Kreismesserscheren mit durchgehender Arbeitswelle werden mit Kreismessern, Rollringen und Distanzhaltern bestückt. For the production of conductor tracks for ribbon cables of different widths and Thickness is mostly wound into a coil of sheet metal in slitting lines (shears) in divided several strips of tape. The separation is done by lossless (chipless) Cutting with circular knives. Circular knife shears with continuous working shaft are equipped with circular knives, roller rings and spacers.
Das Verfahren nach dem Stand der Technik ist im Hauptpatent . . . (Patentanmeldung 101 63 038.7) näher behandelt. Ein Mangel dieses Verfahrens ist der beim Trennen in Verschiedenster Ausprägung entstehende Schneidgrat. Auf die Minimierung der Gratbildung wurden deshalb große Anstrengungen verwendet, beispielsweise werden die Grate nachträglich überwalzt. Alternativ werden auch Press- bzw. Ziehprodukte in Drahtform eingesetzt, die von vornherein im gesamten Querschnitt die definierten Geometrien besitzen. The prior art method is in the main patent. , , (Patent application 101 63 038.7) treated in more detail. A shortcoming of this procedure is that of Separate cutting burrs in various forms. On the Great efforts were therefore made to minimize the formation of burrs for example, the ridges are rolled over afterwards. Alternatively, press or Drawn products used in wire form, from the outset in the entire cross section have the defined geometries.
Im Hauptpatent . . . (Patentanmeldung 101 63 038.7) wird beschrieben, wie die Nachteile der Rollenschnitt-Technik überwunden werden können, ohne hohe Kosten oder geringere Produktivitäten zu verursachen. In the main patent. , , (Patent application 101 63 038.7) describes how the Disadvantages of the roll cutting technique can be overcome without high costs or cause less productivity.
Die Aufgabe wird nach dem Hauptpatent . . . (Patenanmeldung 101 63 038.7) dadurch gelöst, dass das Halbzeug aus duktilem Material, insbesondere Metall, auf gegenüberliegenden Seiten des Halbzeugs mindestens ein Paar keilförmiger Nuten in gegenseitig fluchtender Ausrichtung aufweist und dass zwischen den Spitzen der keilförmigen Nuten ein Steg vorliegt, dessen Dicke d im Vergleich zur Dicke D des Halbzeugs so gering ist, dass er durch gegensinnige Auslenkung der durch das Nutenpaar abgegrenzten Halbzeugbereiche ohne spanende Verformung mit geringem Kraftaufwand abreißbar ist. The task is based on the main patent. , , (Patent application 101 63 038.7) solved in that the semi-finished product made of ductile material, in particular metal opposite sides of the semi-finished product at least a pair of wedge-shaped grooves in mutually aligned alignment and that between the tips of the wedge-shaped grooves a web is present, the thickness d compared to the thickness D of the Semi-finished product is so small that it is due to the opposite deflection of the Grooves pair delimited semi-finished product areas without cutting deformation with little Force is tearable.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu beschreiben, die es ermöglicht, das nach dem Hauptpatent . . . (Patenanmeldung 101 63 038.7) vorbereitete Material in einzelne Bandstreifen zu trennen. Dabei soll es möglich sein, die einzelnen Bandstreifen ohne zusätzliche Zwischenschritte (Aufhaspeln o. ä.) weiteren Verarbeitungsstufen zuzuführen. Die Vorrichtung darf also die Verarbeitungsgeschwindigkeit nachfolgender Prozesse nicht einschränken. The invention has for its object to describe a device that enables that after the main patent. , , (Patent application 101 63 038.7) separate the prepared material into individual strips. It should be possible to individual strip strips without additional intermediate steps (reeling or similar) To supply processing stages. The device can therefore Do not limit the processing speed of subsequent processes.
Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. The object is achieved by a device with the characteristic Features of claim 1 solved.
Bevorzugte Ausführungsformen der Vorrichtung sind Gegenstand der Ansprüche 2 bis Preferred embodiments of the device are the subject of claims 2 to
Die Erfindung wird anhand der folgenden Ausführungsbeispiele näher erläutert. The invention is explained in more detail using the following exemplary embodiments.

Der nach dem Hauptpatent . . . (Patenanmeldung 101 63 038.7) vorbereitete (in Bandrichtung mindestens einmal gekerbte) Bandwickel 1, insbesondere Bandmaterial aus Metall, befindet sich auf dem Abhaspel 2. Er wird gemäß Fig. 1 durch Zustellrollen 3, 4 geführt. Der Spaltabstand der Zustellrollen 3, 4 kann variiert werden. Durch gegensinnige Auslenkung der durch die Nutenpaare abgegrenzte Halbzeugbereiche werden die so entstehenden Bandstreifen abwechselnd oberhalb der Umlenkrolle 5, der benachbarte Bereich unterhalb der Umlenkrolle 6 geführt und anschließend in den Zustellrollen 7, 8 zusammengeführt. Im vorliegenden Fall von vier Bandstreifen 1a, 1b, 1c, 1d werden die Bandstreifen 1a, 1c oberhalb der Umlenkrolle 5, die Bandstreifen 1b, 1d unterhalb der Umlenkrolle 6 geführt (siehe insbes. Fig. 2). Der Abstand der Zustellrollen 7, 8 ist ebenfalls variabel ausgeführt. The one after the main patent. , , (Patent application 101 63 038.7) prepared (at least once notched in the tape direction) tape roll 1 , in particular tape material made of metal, is located on the uncoiler 2 . It is conducted in accordance with FIG. 1 by feed rollers 3, 4. The gap between the feed rollers 3 , 4 can be varied. By deflecting the semifinished product areas delimited by the pairs of grooves, the resulting strip strips are alternately guided above the deflecting roller 5 , the adjacent area below the deflecting roller 6 and then brought together in the feed rollers 7 , 8 . In the present case of four strip strips 1 a, 1 b, 1 c, 1 d, the strip strips 1 a, 1 c are guided above the deflection roller 5 , the strip strips 1 b, 1 d below the deflection roller 6 (see in particular FIG. 2) , The distance between the feed rollers 7 , 8 is also variable.
Die laterale Führung der Bandstreifen 1a, 1b, 1c, 1d wird über geeignete Vorrichtungen am Einlauf 9 für den nächsten Verarbeitungsschritt erreicht (beispielsweise Welle mit Distanzringen). Die so geteilten Halbzeugbereiche (insbesondere Bandstreifen) werden dann weiteren Verarbeitungsstufen 10 (beispielsweise Aufhaspel, Extruder für die Herstellung von Flachbandkabel etc.) zugeführt. The lateral guidance of the strip strips 1 a, 1 b, 1 c, 1 d is achieved via suitable devices at the inlet 9 for the next processing step (for example a shaft with spacer rings). The semi-finished product areas divided in this way (in particular strip strips) are then fed to further processing stages 10 (for example reeling, extruders for the production of ribbon cables, etc.).
Das Einbringen des Halbzeugs in die Vorrichtung kann auch durch alternierendes Auffächern der Bandstreifen an beliebiger Stelle des Bandes geschehen. Dazu wird das Rollenpaar 5, 6 aus der Vorrichtung geschoben und das noch zusammenhängende Halbzeug bis zum Auslauf 9, 10 geführt. Dann wird eine bewegliche, kammförmige Bandauffächerung 13 auf eine starre Bandauffächerung 14 gefahren, die ebenfalls kammartig ausgebildet ist. Die einzelnen Bandstreifen werden abwechselnd von der beweglichen Bandauffächerung 13 nach unten (Bandstreifen 1b, 1d), von der starren Bandauffächerung 14 nach oben verschoben (Bandstreifen 1a, 1c). Anschließend werden durch die Bohrungen 13a, 14a der Bandauffächerungen 13, 14 Bolzen 13b, 14b zum Rückhalt der Bandstreifen 1a bis 1d beim Auseindanderfahren der beweglichen Bandauffächerung 13 eingeführt (s. insbes. Fig. 4). The semi-finished product can also be introduced into the device by alternately fanning out the strip strips at any point on the strip. For this purpose, the pair of rollers 5 , 6 is pushed out of the device and the still connected semi-finished product is led to the outlet 9 , 10 . Then a movable, comb-shaped band fanning 13 is moved onto a rigid band fanning 14 , which is also comb-like. The individual tape strips are alternately (b tape strips 1, 1 d) of the movable Bandauffächerung 13 downwardly from the rigid Bandauffächerung 14 shifted upward (tape strip 1 a, 1 c). Then the holes 13 a, 14 a of the band fanning out 13 , 14 bolts 13 b, 14 b are introduced to retain the band strips 1 a to 1 d when the movable band fanning out 13 moves apart (see in particular FIG. 4).
Beim darauffolgenden Auseinanderfahren der beweglichen Bandauffächerung 13 werden die Bandstreifen 1a, 1c bzw. 1b, 1d so weit voneinander getrennt, dass das Rollenpaar 5/6 wieder in das bereits aufgefächerte Halbzeug eingeschoben werden kann. Das bietet den Vorteil eines noch zusammenhängenden Bandanfangs und damit ein einfaches Einfädeln in den nächsten Verarbeitungsschritt. During the subsequent moving apart of the movable Bandauffächerung 13, the tape strips 1 a, 1 c and 1 b, 1 d so widely separated that the pair of rollers can be 5/6 re-inserted into the already fanned semifinished product. This offers the advantage of a coherent beginning of the tape and thus easy threading into the next processing step.
Die Position der Umlenkrollen 5, 6 zwischen den Zustellrollen 3, 4/7, 8 ist veränderbar. Durch Verschieben des Umlenkrollenpaares 5, 6 kann der Abreißwinkel zwischen den Bandstreifen 1a, 1c bzw. 1b, 1d variiert werden (der Winkel zwischen den Bandstreifen 1a, 1c bzw. 1b, 1d und der Horizontalen beträgt dabei jeweils zwischen 10° und 90°). The position of the deflection rollers 5, 6 between the feed rollers 3, 4/7, 8 can be varied. By moving the pair of guide rollers 5 , 6 , the tear-off angle between the tape strips 1 a, 1 c or 1 b, 1 d can be varied (the angle between the tape strips 1 a, 1 c or 1 b, 1 d and the horizontal is between 10 ° and 90 °).
Die oberen Zustellrollen 4, 8 können mit einer wählbaren Kraft auf die unteren Zustellrollen 3, 7 zugestellt werden. The upper feed rollers 4 , 8 can be delivered to the lower feed rollers 3 , 7 with a selectable force.
Dies wird erreicht durch die Aufhängung der oberen Zustellrollen 4, 8 über Hebel 11, 12 und Kraftaufbringung durch Spindel (mechanisch), durch Zylinder (pneumatisch), hydraulisch oder elektromagnetisch. This is achieved by suspending the upper feed rollers 4 , 8 via levers 11 , 12 and applying force through the spindle (mechanical), through cylinders (pneumatic), hydraulically or electromagnetically.
Die Umlenkrollen 5, 6 können konstant motorisch angetrieben, geregelt motorisch angetrieben oder mitlaufend sein. Bei nicht angetriebenen, mitlaufenden Rollen besteht die Gefahr, dass die Oberfläche durch Schlupf (relative Bewegung Oberfläche Band zu Oberfläche Rolle) beschädigt wird. Dem wird dadurch vorgebeugt, dass die Rollen 5, 6 reibungsmaximiert ausgelegt sind (beispilesweise gummierte Oberfläche). The deflection rollers 5 , 6 can be constantly driven by motor, controlled by motor or can be driven. If the rollers are not driven and run along, there is a risk that the surface will be damaged by slippage (relative movement surface belt to surface roller). This is prevented by the fact that the rollers 5 , 6 are designed to maximize friction (for example, rubberized surface).
Bei angetriebenen Rollen 5, 6 wird der Motor mittels einer Rutschkupplung an die Rolle gekoppelt. Mit der Rutschkupplung kann das maximale Drehmoment so eingestellt werden, dass ein Schlupf verhindert wird. In the case of driven rollers 5 , 6 , the motor is coupled to the roller by means of a slip clutch. With the slip clutch, the maximum torque can be set so that slippage is prevented.
Der Abstand A der Umlenkrollen 5, 6 kann variabel ausgeführt sein. The distance A between the guide rollers 5 , 6 can be made variable.
Der Radius R der Umlenkrollen 5, 6 kann variabel ausgeführt sein. Durch die damit veränderbare Umschlingung kann das Abreißverhalten an unterschiedliche Stegdicken des gekerbten Halbzeugs angepaßt werden. The radius R of the deflection rollers 5 , 6 can be made variable. As a result of the wrapping that can be changed in this way, the tearing behavior can be adapted to different web thicknesses of the notched semifinished product.
Die eingesetzte Banddicke beträgt üblicherweise 0,005 mm bis 0,3 mm, vorzugsweise 0,035 mm bis 0,25 mm. The strip thickness used is usually 0.005 mm to 0.3 mm, preferably 0.035 mm to 0.25 mm.
