Description

Die Erfindung betrifft eine Vorrichtung zum Los- ao lösen und gleichzeitigen Ablegen einzelner von auf einem Stanzautomaten od. dgl. ausgeschnittener und in einem unterhalb der Matrize mit dieser fluchtenden Einsatz durch Reibung an dessen Innenwandung IU einem durch den Stanzstempeldruck im Einsatz entlang geschobenen Paket aufgetauter Bleche.The invention relates to a device for loosing ao and simultaneously storing individual from a punching machine od. The like. Cut out and in one below the die in alignment with this Use due to friction on its inner wall IU one due to the punch pressure in use along the pushed package of defrosted trays.

Bisiang wurden die bei Schnelläuferstanzautomalen in großer Menge und rascher Folge anfallenden Bleche durch einen an den unterhalb der Matrize fluchtenden Ein··atz anschließenden gekrümmten Stapelkanal geleitet und an dessen Ende in der gewünschten Stapelhöhe von Hfr/d entnommen und paketiert.Bisiang were those produced in large numbers and in quick succession with high-speed automatic punching machines Sheet metal through a curved stacking channel adjoining the insert that is aligned below the die and removed at the end of the desired stack height of Hfr / d and packaged.

Die Erfindung hat es sich daher zur Aufgabe gemacht, diesen Vorgang weitestgehend zu automatisieren und somit die selbsttätige, ununterbrochene Bildung von Blechpaketen gewünschter Höhe an einer außerhalb des Maschinenbereichs liegenden Stelle zu ermöglichen, wobei allerdings zuvor ein Vereinzeln der im Einsatz aufgestauten Bleche erforderlich ist.The invention has therefore set itself the task of automating this process as far as possible and thus the automatic, uninterrupted formation of laminated cores of the desired height at one To enable location lying outside of the machine area, although a separation beforehand the metal sheets accumulated during use is required.

Zur Lösung dieser Aufgabe wird bei einer Vorrichtung nach dem Gattungsbegriff daher vorgeschlagen, daß die Innenwandungsteile der Blechaustrittsöffnung des Einsatzes in bekannter Weise einen kleineren Querschnitt als die Matrizenöffnung aufweisen. To solve this problem, it is therefore proposed in a device according to the generic term, that the inner wall parts of the sheet metal outlet opening of the insert in a known manner have a smaller cross-section than the die opening.

Diese Vorrichtungsmerkmale sind zwar bereits in .»Merkblätter über sachgemäße Stahlverwendung«', 195Q1 Nr. 117, S. 7, Bild 35, zum vereinzelten Abziehen von Blechen aus einem Stapel beschrieben, jedoch ist der bei dieser Konstruktion dafür vorgesehene, am unteren Stapelende taktweise angreifende und über ein gesondertes Antriebssystem bewegte Sauger durch seine Rücklaufzeiten nach jedem Entnahmevorgang für Schnelläuferstanzauiomaten ungeeignet. Trotz des bereits jahrzehntelangen ständig hohen Bedarfs an Blechen elektrischer Maschinen wird mit der vorliegenden Konstruktion erstmals die erfindungsgemäße Verwendung der an sich bekannten Vorrichtungsmerkmale vorgeschlagen.These device features are already described in "Leaflets on proper steel use"', 195Q 1 No. 117, p. 7, Fig. 35, for the individual removal of sheets from a stack, but the one provided for this design is at the bottom end of the stack Cyclic suction cups that are moved via a separate drive system are unsuitable for high-speed punch presses due to their return times after each removal process. Despite the constant high demand for sheet metal electrical machines for decades, the present construction proposes for the first time the use according to the invention of the device features known per se.

Die Erfindung wird nachstehend an Hand eines Ausführungsbeispieles beschrieben.The invention is described below using an exemplary embodiment.

Die einzige Zeichnung zeigt die Vorrichtung an einem Stanzautoniaten, teilweise im Schnitt.The only drawing shows the device on a punching machine, partly in section.

Auf einem Tisch 1 einer Stanze ist eine Aufspannplatte 2 befestigt, auf der ein Unterteil 3 einer Ausschneidevorrichtung aufgespannt ist. Ein Werkzeu»- oberteil 4 ist an einem Pressenstößel 5 befestigt und schneidet aus einem Vorwerkstück 6 durch eine Matrize 7 des Unterteils 3 gelochte Bleche 8 aus. Diese Bleche 8 celangen in einen Einsatz 9 und stauen sich dort zu einem Stapel 10. Bei gefülltem Einsatz 9 wird das jeweils unterste der Bleche 8 des Stapels 10 bei jedem weiteren Stößelhub aus dem Einsatz 9 herausgedrückt, fällt auf ein Band 11. welches die Bleche 8 in sich teilweise überdeckender Lage der am abgabeseitigen Bandende angeordneten Stapelvorrichtung 12 zuführt.A clamping plate 2, on which a lower part 3 of a cutting device is clamped, is fastened to a table 1 of a punch. A tool upper part 4 is attached to a press ram 5 and cuts perforated metal sheets 8 from a preliminary workpiece 6 through a die 7 of the lower part 3. These sheets 8 celangen in an insert 9 and accumulate there to form a stack 10. When the insert 9 is full, the bottom of the sheets 8 of the stack 10 is pushed out of the insert 9 with each further ram stroke, falls onto a belt 11. which holds the sheets 8 in a partially overlapping position of the stacking device 12 arranged at the delivery-side end of the belt.

Der Einsatz 9 ist hierbei derart gestaltet, daß seine dem Band 11 zugewandte Seite einen kleineren Öffnungsquerschnitt aufweist als der Querschnitt der Bleche 8 ist. Hierdurch wird erreicht, daß sich die Bleche 8 im unteren verjüngten Bereich des Stapels 10 durchwölben, durch die gegenseitige Verschiebung bedingt selbst auf anhaftendem Schmiermktelfilm einzeln abspringen und auf das Band 11 fallen.The insert 9 is designed in such a way that its the band 11 facing side has a smaller opening cross section than the cross section of the Sheet 8 is. This ensures that the sheets 8 are in the lower tapered area of the stack 10 arch through, due to the mutual displacement, even on adhering smear film Jump off individually and fall onto the belt 11.
