Description

Die Erfindung betrifft eine Vorrichtung zum schritt­ weisen Zuführen von Blechstreifen mittels Schiebe­ klinken in den Werkzeugraum einer Presse.The invention relates to a device for step assign feeding of sheet metal strips by means of sliding click into the tool room of a press.

Derartige Vorrichtungen werden benötigt, um Pressen mit Blechstrefen zu beschicken, um z. B. Platinen daraus zu schneiden, wobei die Streifenlänge immer ein Mehrfaches der Vorschublänge ist und die Folge der Streifen so dicht sein muß, daß nach Ver­ arbeitung des einen Streifens ohne Stillstand oder Leerhub der Presse der nächste bearbeitet werden kann.Such devices are required to press to feed with sheet metal struts to z. B. circuit boards cut from it, always keeping the strip length is a multiple of the feed length and the result the strip must be so dense that according to Ver work of one strip without standstill or Idle stroke of the press the next to be processed can.

Die bisher bekannten Einrichtungen sind so aufgebaut, daß eine mit gefederten Klinken bestückte Schiene durch hin- und hergehende Bewegung das Blech um jeweils einen Schritt weitertransportiert, wobei der Klinkenabstand immer genau der Vorschublänge und die Klinkenanzahl der Anzahl der Vorschubschritte entspricht (eigene Konstruktion).The previously known facilities are structured in such a way that a rail equipped with spring-loaded pawls by moving the sheet back and forth transported one step at a time, whereby the pawl distance is always exactly the feed length and the number of pawls the number of feed steps corresponds (own construction).

Der Nachteil hierbei ist, daß für jede Vorschublänge eine separate Klinkenschiene benötigt wird, welche beim Werkzeugwechsel manuell ausgewechselt werden muß und daß die relativ schwere Schiene nach jedem Vorschub den gleichen Weg wieder zurückfahren muß, was eine große Antriebsleistung erfordert.The disadvantage here is that for each feed length a separate jack rail is required, which be replaced manually when changing tools must and that the relatively heavy rail after each Feed must go back the same way, which requires a large drive power.

Hier setzt nun die vorliegende Erfindung ein und hat sich zur Aufgabe gestellt, das Umrüsten auf eine andere Vorschublänge zu automatisieren, wobei die sich bewegenden Massen möglichst klein gehalten werden.This is where the present invention comes in and has set himself the task of converting to another Automate feed length, taking the moving masses are kept as small as possible.

Diese Aufgabe wird durch die im Anspruch an­ gegebene Erfindung gelöst. This task is claimed by the given invention solved.  

Die erfindungsgemäße Vorrichtung kann somit ohne Umzu­ rüsten für verschiedene Streifenlängen und Anzahl von Vorschubschritten eingesetzt werden.The device according to the invention can thus without moving prepare for different strip lengths and number of Feed steps are used.

Die Erfindung wird anhand einer Zeichnung, die ein be­ liebiges Ausführungsbeispiel darstellt, näher erläu­ tert. Es zeigtThe invention is based on a drawing, which be represents any preferred embodiment, explained in more detail tert. It shows

Fig. 1 eine Seitenansicht der Vorrichtung, Fig. 1 is a side view of the apparatus,

Fig. 2 eine entsprechende Draufsicht und Fig. 2 is a corresponding top view and

Fig. 3 eine Vorderansicht der Antriebseinheit. Fig. 3 is a front view of the drive unit.

In der Ausgangsstellung liegt eine Schiebeklinke 1 an einer Schnittkante 3 eines Werkzeuges 4 an.In the starting position, a sliding pawl 1 bears against a cutting edge 3 of a tool 4 .

Eine Schiebeklinke 2 ist mit Hilfe eines Überlagerungs­ getriebes 5 und eines Motors 6 so eingestellt, daß sie unmittelbar hinter einem Blechstreifen 7 liegt. Nun schiebt die Schiebeklinke 2, angetrieben durch einen Schrittmotor 8, ein Abzweigungsgetriebe 9 und einen Linearantrieb 10 den Blechstreifen 7 in das Werkzeug 4, bis die Vorderkante des Blechstreifens 7 an einem Anschlag 11 anliegt, wobei kleine Vorschubfehler durch eine Feder 12 ausgeglichen werden.A sliding pawl 2 is adjusted with the aid of a superposition gear 5 and a motor 6 so that it lies immediately behind a sheet metal strip 7 . Now, the sliding pawl 2 , driven by a stepper motor 8 , a branching gear 9 and a linear drive 10, pushes the sheet metal strip 7 into the tool 4 until the front edge of the sheet metal strip 7 abuts a stop 11 , small feed errors being compensated for by a spring 12 .

Während dessen bewegt sich die Schiebeklinke 1, ange­ trieben durch dasselbe Antriebssystem um den gleichen Weg vom Werkzeug 4 weg.During this time, the sliding pawl 1 is driven by the same drive system by the same path from the tool 4 .

Der Blechstreifen 7 wird nun an der Schnittkante 3 des Werkzeuges 4 abgeschnitten und die anfallende Platine 13 durch ein werzeuginternes Fördersystem abtranspor­ tiert.The sheet metal strip 7 is now cut off at the cutting edge 3 of the tool 4 and the resulting board 13 is transported away by an internal conveyor system.

Die Schiebeklinke 2 schiebt nun den Blechstreifen 7 in weiteren Schritten ins Werkzeug 4, bis er aufge­ arbeitet ist. Hat die Schiebeklinke 2 den letzten Vor­ schub beendet, ist die Schiebeklinke 1 in ihrer hinteren Stellung und kann einen neuen, inzwischen ein­ gelegten Blechstreifen 7 übernehmen und der beschrie­ bene Vorgang wiederholt sich bei reversiertem Antrieb.The sliding pawl 2 now pushes the sheet metal strip 7 in further steps into the tool 4 until it is up. Has the sliding pawl 2 completed the last advance, the sliding pawl 1 is in its rear position and can take a new, now a sheet metal strip 7 and the described process is repeated with reversed drive.
