Abstract

A hydraulic cylinder (1) moves a gear rack (2) to and fro. The rack drives a pinion (3). The pinion is mounted on a shaft (4) which is supported on two bearings and the shaft carries a free-wheel, so that the movement of the pinion is not transmitted on the return stroke of the rack. the shaft drives the transport roller (6) intermittently via a torque converter (7). An electric motor (12) can drive the transport roller (6) continuously. It is used to adjust the workpiece position, via a gear drive (10) and coupling (11). The torque converter gives a fine adjustment transmissions to the transport roller.

Description

zwecks Einführung und Einrichten des nicht dargestellten bandförmigen Werkstückes kontinuierlich angetrieben werden. Der Drehmomentwandler 7 mit einer Drehfühlerwelle 8 bewirken einen feinfühligen Antrieb, da sie ein Einwirken der großen umlaufenden Massen der Vorschubwalze 6 auf das Vorschubgerät verhindern.for the purpose of introducing and setting up the band-shaped, not shown Workpiece are continuously driven. The torque converter 7 with a Rotary sensor shaft 8 cause a sensitive drive, as they have an effect of the Prevent large rotating masses of the feed roller 6 on the feed device.

Patentanspruch: Anordnung zum Einführen und Einrichten von band- oder stangenförmigen Werkstücken an einem Vorschubgerät mit absatzweisen Antrieb, der über einen Freilauf auf die Antriebswelle arbeitet, dadurch gekennzeichnet, daß zwischen dem Freilauf (5) und einem in die Antriebswelle (4) eingeschalteten Drehmomentwandler (7) ein an sich bekannter, auf die Antriebswelle kontinuierlich wirkender Antrieb (10,11,12) einkuppelbar ist Die Erfindung betrifft eine Vorschubanordnung für band- oder stangenförmige Werkstücke und absatzweisen Antrieb durch einen Arbeitszylinder und hin- und hergehende Zahnstange. Hierbei ist auf der Antriebswelle vor der Vorschubwalze ein Freilauf angeordnet, der verhindern soll, daß beim Zurückziehen der Zahnstange eine gegensinnige Drehbewegung an der Vorschubwalze entsteht Bei einem derartigen Vorschubgerät ergeben sich Schwierigkeiten beim Einführen und Einrichten des bandförmigen Werkstückes. Es war vor allem schwierig, das Werkstück in die genaue Arbeitsstellung des weiterverarbeitenden Gerätes zu bringen. Claim: arrangement for introducing and setting up tape or rod-shaped workpieces on a feed unit with a step-by-step drive, which works via a freewheel on the drive shaft, characterized in that that switched between the freewheel (5) and one in the drive shaft (4) Torque converter (7) a known per se, on the drive shaft continuously Acting drive (10, 11, 12) can be coupled. The invention relates to a feed arrangement for strip or rod-shaped workpieces and step-by-step drive by a working cylinder and reciprocating rack. Here is on the drive shaft in front of the feed roller arranged a freewheel, which is to prevent that when retracting the rack a rotation in the opposite direction on the feed roller arises with such a Feeder difficulties arise when inserting and setting up the band-shaped Workpiece. Above all, it was difficult to get the workpiece in the exact working position of the further processing device. Der Erfindung liegt die Aufgabe zugrunde, das Einrichten des Werkstückes zu erleichtern. Die Aufgabe wird durch die im Anspruch angegebene Erfindung gelöst Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles beschrieben. The invention is based on the object of setting up the workpiece to facilitate. The object is achieved by the invention specified in the claim The invention is described below using an exemplary embodiment. Durch einen Arbeitszylinder 1 wird über eine hin- und hergehende Zahnstange 2 und ein Ritzel 3 eine Antriebswelle 4, die beiderseitig gelagert ist, angetrieben. Auf der Antriebswelle 4 sitzt ein Freilauf 5, der beim Zurückziehen der Zahnstange 2 die Übertragung einer gegensinnigen Drehbewegung auf eine Vorschubwalze 6 vermeidet Auf der Antriebswelle 4 ist zwischen einem Drehmomentwandler 7 und dem Freilauf 5 die wahlweise Einführung eines kontinuierlichen Antriebes möglich. Über ein Ritzel 10 und eine Kupplung 11 kann durch einen Elektromotor 12 die Vorschubwalze 6 z. B. By a working cylinder 1 is a reciprocating Rack 2 and a pinion 3 a drive shaft 4, which is supported on both sides, driven. On the drive shaft 4 there is a freewheel 5, which when retracted of the rack 2, the transmission of a rotational movement in the opposite direction to a feed roller 6 avoids On the drive shaft 4 is between a torque converter 7 and the Freewheel 5 the optional introduction of a continuous drive is possible. Above a pinion 10 and a clutch 11 can drive the feed roller by an electric motor 12 6 z. B.
