Abstract

Articulated on the rocker are arms (13, 14) which carry the clamping bar (46). At the opposite end, these arms are articulated on the housing (1) in such a way that, in one position, the axis (48) of rotation of the lower feed roll (2) coincides with the swivelling axis (52) of the articulation point of the swivelling arms on the housing (1). The clamping bar (46) is articulated on the housing at a swivelling point (82) via a linkage (80, 81) in such a way that a motion parallelogram is formed, in accordance with which the clamping bar (46) is moved at right angles towards the workpiece (43) to be clamped. This permits better clamping of the workpiece (43). …<IMAGE>…

Description

Die vorliegende Erfindung betrifft eine Vorrich­tung nach dem Oberbegriff des Patentanspruches 1.The present invention relates to a device according to the preamble of claim 1.

In der Schweizer Patentanmeldung Nr. 3984/88-1 ist eine Ausführung einer solchen Vorrichtung bekannt ge­worden, bei welcher das Anpresslineal 46 fest mit den Armen 13,14 verbunden sind. Diese Ausführung ist z.B. in der Figur 2 der genannten Anmeldungsschrift gezeigt.In the Swiss patent application No. 3984 / 88-1, an embodiment of such a device is known in which the pressure ruler 46 is firmly connected to the arms 13, 14. This version is e.g. shown in Figure 2 of said application.

Folglich bewegt sich das Anpresslineal entlang eines Kreisbogens gegen das anzupressende bandförmige Werkstück, so dass nicht in jedem Fall eine einwandfreie Flächenberührung zwischen dem Anpresslineal 45 und dem Werkstück 43 vorhanden ist.As a result, the contact ruler moves along an arc against the band-shaped workpiece to be pressed, so that there is not always a perfect surface contact between the contact ruler 45 and the workpiece 43.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie im Anspruch gekennzeichnet ist, löst die Aufgabe, eine Vorrichtung zum schrittweisen Vorschie­ben eines bandförmigen Werkstückes zu schaffen, bei der das Anpresslineal zwischen Schwenkarmen angeordnet ist, die an der Wippe und an einem Rahmenteil angelenkt sind und weiter über einen Zwischenträger an den Schwenkarmen angelenkt ist, welcher Zwischenträger seinerseits mit dem Gehäuse schwenkbar verbunden ist.The invention seeks to remedy this. The invention, as characterized in the claim, solves the problem of creating a device for the gradual advancement of a band-shaped workpiece, in which the contact ruler is arranged between swivel arms which are articulated on the rocker and on a frame part and further via an intermediate support the pivot arms is articulated, which intermediate carrier is in turn pivotally connected to the housing.

Der durch die Erfindung erreichte Vorteil ist im wesentlichen darin zu sehen, dass das Anpresslineal gerad­linig und rechtwinklig gegen das zu arretierende Werkstück bewegt werden kann, so dass beim Arretieren eine Flächen­berührung, bzw. Flächenpressung stattfindet.The advantage achieved by the invention is essentially to be seen in the fact that the pressure ruler can be moved in a straight line and at right angles to the workpiece to be locked, so that when it is locked a surface contact or surface pressure takes place.

Im folgenden wird die Erfindung anhand von einer lediglich einen Ausführungsweg darstellenden Zeichnung näher erläutert.The invention is explained in more detail below with reference to a drawing which represents only one embodiment.

Ziel der Erfindung ist, den angeführten Nachteil zu beheben.The aim of the invention is to remedy the disadvantage mentioned.

Die erfindungsgemässe vorrichtung ist durch die Merkmale des Patentanspruches 1 gekennzeichnet.The device according to the invention is characterized by the features of claim 1.

Nachfolgend wird der Erfindungsgegenstand anhand der Zeichnung beispielsweise näher erläutert.The subject matter of the invention is explained in more detail below with reference to the drawing, for example.

Es zeigt:It shows:

Die einzige Zeichnungsfigur zeigt eine Ausfüh­rung der erfindungsgemässen Vorrichtung.The only drawing figure shows an embodiment of the device according to the invention.

Aus Gründen der Uebersichtlichkeit sind in der Figur nur diejenigen Bezugsziffern eingetragen, welche zum Verständnis dieser Ausführung notwendig sind. Dabei sind die Bauteile, welche in den Figuren der Anmeldung Nr.3984/­88-1, insbesondere der Figur 2 gezeigt sind, mit denselben Bezugsziffern bezeichnet.For reasons of clarity, only those reference numbers are entered in the figure which are necessary to understand this embodiment. The components which are shown in the figures of application No. 3984/88-1, in particular in FIG. 2, are identified by the same reference numbers.

Das Anpresslineal 46 weist einen rechteckigen oder quadratischen Querschnitt auf. Das Anpresslineal ist fest mit einem Zwischenträger 80 verbunden bzw. einstückig damit ausgebildet, welcher Zwischenträger aus z.B. zwei parallelen Tragstangen gebildet sein kann. Der Zwischen­träger 80 ist bei einer Schwenkstelle 85 an den Schwenk­armen 13,14 angelenkt. Bei seinem oberen Ende ist der Zwsichenträger 80 weiter an Lenkern 81 angelenkt, welche ihrerseits bei einer Schwenkstelle 82 am Gehäuse angelenkt sind. Dabei sind die jeweiligen Schwenkstellen derart an­geordnet, dass sich die Schwenkstelle 82 der Lenker 81 am Gehäuse auf einer Geraden 83 befindet, welche durch die Rotationsachse der sich in der Anpressstellung befindli­chen oberen Vorschubwalze 3 und senkrecht zur Vorschub­ebene des bandförmigen Werkstückes 43 verläuft. Die obere Anlenkstelle des Zwischenträgers 80, bei welcher dieser an den Lenkern 81 angelenkt ist und die untere Anlenk­stelle 85, bei welcher der Zwischenträger 80 an den Schwenkarmen 13,14 angelenkt ist, liegen auf einer weite­ren Gerade 84, welche parallel zur erstgenannten Geraden 83 verläuft. Damit ist eine parallelogrammförmige Anord­nung geschaffen, bei welcher das Anpresslineal 46 während den Schwenkbewegungen der Schwenkarme 13,14 eine senk­recht zur Vorschubebene des bandförmigen Werkstückes 43 verlaufenden Gerade oszillierend bewegt, so dass eine geradlinige Bewegung des Anpresslineals 46 gegen das an­zupressende Werkstück und von diesem weg erzielt ist. Die­se Bewegungsart stellt ein einwandfreies Anpressen der Auflagefläche des Anpresslineals 46 sicher.The pressure ruler 46 has a rectangular or square cross section. The pressure ruler is fixedly connected to an intermediate support 80 or is formed in one piece with it, which intermediate support can be formed from, for example, two parallel support rods. The intermediate carrier 80 is articulated at a pivot point 85 on the pivot arms 13, 14. At its upper end, the intermediate carrier 80 is further articulated on links 81, which in turn are articulated on the housing at a pivot point 82. The respective pivot points are arranged in such a way that the pivot point 82 of the link 81 on the housing is located on a straight line 83 which runs through the axis of rotation of the upper feed roller 3 located in the pressing position and perpendicular to the feed plane of the band-shaped workpiece 43. The upper articulation point of the intermediate support 80, at which this is articulated on the links 81 and the lower articulation point 85, at which the intermediate support 80 is articulated on the swivel arms 13, 14, lie on a further straight line 84, which is parallel to the first-mentioned straight line 83 runs. This creates a parallelogram-shaped arrangement in which the contact ruler 46 oscillates a straight line perpendicular to the feed plane of the band-shaped workpiece 43 during the pivoting movements of the pivot arms 13, 14, so that a linear movement of the contact ruler 46 against and against the workpiece to be pressed is achieved is. This type of movement ensures that the contact surface of the pressure ruler 46 is pressed on properly.
