Abstract

The swarf remover, for producing records or signal-recording discs, has a tube (4) connected at one end to a suction chamber (8) and lying with its other end near the cutting tool (1). The chamber is connected to a pump (7). Swarf (3) cut from the disc is sucked into the tube and wound up inside the chamber. The swarf passes along the tube and between two roller (6) inside the chamber. The rollers are connected via a slip coupling to a drive. The rollers are held together sandwiching the swarf between them by a spring (9). The Rollers are not driven at constant speed since the diameter of the groove being cut is always decreasing. The slip coupling ensures that the tension in the swarf remains constant despite this change in diameter.

Description

Vorrichtung zum Abführen des Spanes beim Schneiden vonDevice for removing chips when cutting

metallischen Signalaufzeichnungsträgern Beim Schneiden von Signalen in ebene, plattenförmige Aufzeichnungsträger wird der in den Rillen entstehende Span im allgemeinen mittels Luft abgesaugt. Dies läßt sich beim Schneiden in Wachsplatten oder in Lackfolien, die wie üblich auf einem Aluminiumträger aufgebracht sind, verhältnismäßig leicht und betriebssicher durchführen, da der Span elastisch genug ist.metallic signal recording media When cutting signals the recording medium produced in the grooves becomes flat, disk-shaped recording media Chip generally extracted by means of air. This can be done when cutting in wax sheets or in lacquer foils, which are applied as usual to an aluminum carrier, proportionally can be carried out easily and reliably, as the chip is elastic enough.

Beim Schneiden in metallische Träger, vorzugsweise Kupferträger, läßt sich dieses Verfahren nicht anwenden, insbesondere, wenn der Träger für die Schallplattenherstellung vorgesehen ist. Beim Beginn des Schneidvorganges ist der Span noch dünn und damit so elastich, daß er noch von der Saugluft weggeführt werden kann. Sobald der Span aber bei der Fortsetzung des Schneidvorganges dicker wird, ist der sich ergebende Metallspan nicht mehr elastisch genug, um von dem Saugluftstrom einwandfrei abgeführt zu werden. Es müssen daher zusätzliche Maßnahmen getroffen werden, die ein einwandfreies Schneiden des Aufzeichnungsträgers ermc;glichen.When cutting into metallic supports, preferably copper supports, leaves Do not use this process, especially if the carrier is used for record production is provided. At the beginning of the cutting process, the chip is still thin and therefore thin so elastic that it can still be led away from the suction air. As soon as the chip but as the cutting process continues, the resulting thickness becomes thicker Metal chips are no longer elastic enough to be properly discharged by the suction air flow to become. It must therefore be taken additional measures that a impeccable Allow cutting of the recording medium.

Die Auf gabe der Erfindung ist es, eine Vorrichtung anzugeben, mit der eine einwandfreie Spanabfuhr auch bei metallischen Aufzeichnungsträgern gewährleistet ist.The task of the invention is to provide a device with which ensures perfect chip evacuation even with metallic recording media is.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene erfindungsgemäße Vorrichtung gelöst.This object is achieved by the specified in claim 1 according to the invention Device solved.

Gemäß der Erfindung wird der Saugvorrichtung eine den Span zusätzlich abführende Vorrichtung zugeordnet. Diese Vorrichtung kann beispielsweise so ausgebildet sein, daß der von der Saugluft durchströmte Span-Sammelbehälter mit einem den Span zunächst aufnehmenden, rohrförmigen Ansatz versehen ist, an dessen mit dem Sammelbehälter verbundenen Ende zwei, eine konstante Zugkraft ausübende Rollen angeordnet sind, zwischen denen der Span geführt wird und die so den Span abziehen und dann dem Sammelbehälter zuführen.According to the invention, the suction device also has a chip assigned discharge device. This device can for example be designed in this way be that the chip collector through which the suction air flows with a chip initially receiving, tubular extension is provided on which with the collecting container connected end two rollers exerting a constant tensile force are arranged, between which the chip is guided and which pull off the chip and then the collecting container respectively.

Die Erfindung wird nachstehend an Hand eines Ausführungsbeispiels näher erläutert.The invention is described below using an exemplary embodiment explained in more detail.

Der Stichel 1 schneidet beim Aufzeichnungsvorgang aus dem metallischen Aufzeichnungsträger 2 einen Span 3 heraus, der mittels der durch Pfeile 7 gekennzeichneten Saugluft in den rohrförmigen Ansatz 4 des Sammelbehälters 8 gezogen wird. Bevor der Span in den Sammelbehälter 8 gelangt, wird er über die beiden, eine konstante Zugkraft ausübende Rollen 5 und 6 geführt. Durch die Federzug werden die beiden Rollen 5 und 6 zusammengehalten.The stylus 1 cuts from the metallic during the recording process Recording medium 2 a chip 3 out, which by means of the indicated by arrows 7 Suction air is drawn into the tubular extension 4 of the collecting container 8. Before the chip arrives in the collecting container 8, it becomes a constant over the two Rollers 5 and 6 which exert traction are guided. The spring balancer makes the two Rolls 5 and 6 held together.

Die Rollen 5 und 6 werden nicht mit konstanter Drehzahl angetrieben, da beim Schneiden der Rille der Durchmesser der Rillenspirale immer kleiner wird. Daher muß eine dem abnehmenden I#illendurchmesser entsprechende so veränderliche Drehzahl gewählt werden, daß das Drehmoment an den Antriebsrollen und damit die Zugkraft des Spans konstant bleibt. Dies läßt sich in vorteilhafter Weise dadurch ermöglichen, daß die Rollen über eine Schlupfkupplung angetrieben werden. Der in den Sammelbehälter 8 gelangende Span 3 könnte auch auf einer besonderen Aufwickelrolle aufgewickelt werden.The rollers 5 and 6 are not driven at constant speed, because when the groove is cut, the diameter of the groove spiral becomes smaller and smaller. Therefore must one corresponding to the decreasing sleeve diameter variable speed can be selected that the torque at the drive rollers and so the tensile force of the chip remains constant. This can be advantageous In this way, enable the rollers to be driven via a slip clutch will. The chip 3 arriving in the collecting container 8 could also be on a special one Take-up roll.
