Derartige Vorschubsysteme dienen der Zufuhr von Tafelmaterial, z.B. Tafeln aus Stahl- oder Aluminiumblech, zu einer Stanzpresse, die aus den Tafeln entsprechend dem eingesetzten Werkzeug Rohlinge ausstanzt, z.B. runde Deckel für Dosen.Such feed systems serve the supply of sheet material, e.g. Sheets of steel or aluminum sheet, to a punch press, which corresponds to the tables punching out blanks, e.g. round lids for cans.
Aus DE-C-43 09 949 und DE-C-43 45 184 ist ein gattungemäße Vorschubsystem für eine Stanzpresse mit einem zweireihigen Werkzeug bekannt, bei welchem der Vorschub mit zwei Vorschubeinrichtungen erfolgt, die einander eine in der Stanzpresse befindliche Tafel übergeben. Die erste Vorschubeinrichtung weist zwei Greifzangen auf, die in dem Zwischenraum zweier Gleitflächen für die Tafeln angeordnet sind und durch unterhalb der Gleitflächen angeordnete Betätigungsmittel betätigt werden. Ein seitlich der einen Gleitfläche angeordneter Verstellantrieb sorgt für die Vorschubbewegung. Die zweite Vorschubeinrichtung weist einen oberhalb der Gleitflächen bewegbaren Schlitten auf, der Arme mit Greifzangen trägt. Der Schlitten wird durch einen weiteren Vorschubantrieb bewegt.DE-C-43 09 949 and DE-C-43 45 184 is a genre Feed system for a punch press with a double row Tool known in which the feed with two Feed devices takes place, one another in the Hand over the punching press. The first feed device has two grippers, which in the Space between two sliding surfaces arranged for the panels are and arranged below the sliding surfaces Actuating means are actuated. One side of the one Sliding surface arranged adjustment ensures the Feed movement. The second feed device has a slide movable above the sliding surfaces, the arms with tongs carries. The sled is going through moves another feed drive.
DE-C 41 35 901 zeigt ein Vorschubsystem mit einer Vorschubeinrichtung und einem Vorlageschlitten, wobei zwischen diesen eine Übergabe der jeweiligen Tafel beim ersten Stanzschritt erfolgt. Es wird dabei ein einreihiges Stanzwerkzeug gezeigt, so dass zusätzlich noch eine Verschiebung der Tafel in zur Vorschubrichtung senkrechter Richtung erfolgt, um eine möglichst dichte Bestanzung der Tafel zu erzielen. Ein weiteres Vorschubsystem ist in DE-C 34 37 642 gezeigt. DE-C 41 35 901 shows a feed system a feed device and a feed carriage, wherein between these a handover of each panel takes place at the first punching step. It is doing a single-row Punching tool shown, so in addition to that a shift of the panel in the direction perpendicular to the feed direction Direction is done to dense as much as possible to achieve the blackboard.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Vorschieben von Blechen bzw. eine Vorschubvorrichtung zu schaffen, welche möglichst einfach auf verschiedene Blechtafelformate umrüstbar ist und den Vorschub auch sehr schmaler Blechtafeln ermöglicht.The invention is based on the object Method for advancing sheets or a feed device to create that as easy as possible various sheet metal formats can be converted and the feed also allows very narrow metal sheets.
Diese Aufgabe wird bei dem Verfahren der eingangs
genannten Art mit den Merkmalen des
Anspruchs 1 gelöst.This task is used in the method of the beginning
mentioned type with the characteristics of
Dadurch, dass beide Vorschubeinrichtungen oberhalb der das Blech tragenden Ebene, in der Regel des die Vorschubebene bildenden Tisches, angeordnet sind, ist eine Verstellung dieser Vorschubeinrichtungen zur Anpassung an die Blechtafelbreite möglich, ohne dass entsprechende Ausnehmungen in der Ebene bzw. im Tisch notwendig sind, die die ebene Auflage des Bleches verschlechtern. Dadurch, dass ferner nur die Greifmittel der zweiten Vorschubeinrichtung durch die erste Vorschubeinrichtung hindurchgreifen, während der Rest der zweiten Vorschubeinrichtung stets hinter der ersten Vorschubeinrichtung plaziert bleibt, kann die Breiteinstellung bis hinunter zu sehr schmalen Blechstreifen ohne Probleme erfolgen bzw. die Breiteneinstellung der ersten Vorschubeinrichtung wird durch die die Greifmittel der zweiten Vorschubeinrichtung tragende Struktur nicht behindert.Due to the fact that both feed devices above the plane supporting the sheet metal, usually the the feed level forming table are arranged is an adjustment of these feed devices for adaptation to the metal sheet width possible without the appropriate Recesses in the plane or in the table necessary are that worsen the flat pad of the sheet metal. Characterized in that further only the gripping means of the second feed device pass through the first feed device, during the rest of the second feed device always placed behind the first feed device The width setting can go down to very narrow metal strips without problems or the width adjustment of the first feed device is by the gripping means of the second feed device supporting structure not obstructed.
Der Erfindung liegt ferner die Aufgabe zugrunde eine Vorschubvorrichtung zu schaffen, die eine möglichst einfache Umrüstung auf verschiedene Tafelformate zulässt und auch sehr schmale Tafeln vorschieben kann.The invention is also based on the object to provide a feed device, the one simple conversion to different board formats allows and can also advance very narrow boards.
Diese Aufgabe wird mit den
Merkmalen des Anspruchs 3 gelöst.This task is with the
Characteristics of
Im folgenden werden Ausführungsbeispiele der
Erfindung anhand der Figuren näher erläutert. Dabei zeigt
Die Figuren 1 bis 3 zeigen schematisch in
Draufsicht und Seitenansicht die Vorschubvorrichtung 1,
welche vor einer Stanzeinrichtung 2 angeordnet ist, die
ein Werkzeug 4 aufweist, welches aus einer Blechtafel 3
Gegenstände 5 ausstanzt (Stanzlöcher sind
beispielhaft gezeigt), so dass nach der Stanzung diese
Gegenstände vereinzelt vorliegen und von der Blechtafel 3
nur noch ein Restgitter besteht. Die Art und Weise der
Stanzung wird hier, da bekannt, nicht näher erläutert. Es
kann auf bekannte Weise eine Stanzung mit einem zweireihigen
Werkzeug stattfinden, so dass das jeweilige Blech
nur in Vorschubrichtung A durch die Stanzeinrichtung 2
geschoben werden muss, oder es kann auf ebenfalls bekannte
Weise eine Stanzung mit einem einreihigen Werkzeug
stattfinden, wobei dann das Blech noch in einer Richtung
senkrecht zur Richtung A hin und her verschoben werden
muss, was bekannt ist. Nachfolgend wird die Vorschubeinrichtung
1 so erläutert, dass sie nur den Vorschub in
Richtung A durchführt. Sollte auch eine Hin- und Herbewegung
senkrecht dazu erforderlich sein, so kann diese
durch weitere Betätigungselemente ohne weiteres ausgeführt
werden, was indes nachfolgend nicht weiter erläutert
wird.FIGS. 1 to 3 show schematically in FIG
Top view and side view of the
Die Vorschubeinrichtung 1 weist bevorzugterweise
ein Trag- und Führungsglied 6 auf, an welchem
Schlitten 7 und 12 in Vorschubrichtung und in Gegenrichtung
beweglich angeordnet sind. Die Schlitten werden
durch einen nicht näher dargestellten Antrieb 17 in Vorschubrichtung
und in Gegenrichtung bewegt, z.B. durch
Zahnriemen oder Ketten, die um Rollen 18, 19 im Tragglied
6 umlaufen, und an welchen die Schlitten befestigt sind.
Natürlich sind auch beliebige andere Antriebe der Schlitten
mit Spindeln oder mit Linearantrieben dem Fachmann
geläufig und ohne weiteres realisierbar. Der Antrieb für
die Schlitten wird durch eine Steuerung 25 gesteuert,
welche auch Signale von Lagesensoren 26 für das Blech
empfangen kann und welche weiter mit der Steuerung 27 für
die Stanzeinrichtung 2 in Verbindung steht, um den Vorschub
und das Stanzen zu synchronisieren. Die Steuerung
25 kann die Lage der Schlitten ebenfalls durch Sensoren
oder durch Geber am Antrieb 17 erkennen.The
Die Vorschubvorrichtung 1 arbeitet auf an
sich bekannte Weise derart, dass die erste Vorschubvorrichtung
7-10 ein von einem nicht gezeigten Stapel abgestapeltes
Blech 3, welches auf dem Vorschubtisch 20 abgelegt
wird, ergreift und in Richtung auf die Stanzeinrichtung
vorschiebt. Eine zweite Vorschubeinrichtung 12-15
ist gleichzeitig damit beschäftigt, ein vorangehendes
Blech durch die Stanzeinrichtung 2 zu führen, wobei dies
auf bekannte Weise in Synchronisation mit der Stanzbewegung
erfolgt. In einer Übergabestellung, welche in Figur
2 dargestellt ist, wird ein von der ersten Vorschubeinrichtung
7-10 in die Stanzeinrichtung 2 eingeschobenes
Blech an die zweite Vorschubeinrichtung 12-15 übergeben.
Diese Übergabe kann z.B. und wie in Figur 2 gezeigt, bei
der ersten Stanzung erfolgen, kann aber natürlich auch
erst später nach einigen Stanzvorgängen erfolgen. Die
Übergabe erfolgt dadurch, dass die Greifmittel 10 der ersten
Vorschubeinrichtung und die Greifmittel 15 der zweiten
Vorschubeinrichtung auf die gleiche Vorschubhöhe gelangen,
so dass die Greifmittel 15 das Blech greifen können,
das bisher von den Greifmitteln 10 gehalten wurde,
wobei diese das Blech freigeben.The
Die Greifmittel 10 bzw. 15 weisen an sich bekannte
zangenartige Bauelemente auf, welche zum öffnen und
Schliessen betätigt werden können, um das jeweilige Blech
loszulassen bzw. zu greifen. Die Greifmittel 10 und 15
weisen zudem in Förderrichtung gesehen nach hinten weisende
Fortsätze 9 bzw. 14 auf, welche die Greifzangen
mit Führungs- und Betätigungselementen 8 bzw. 13 auf den
Schlitten 7 bzw. 12 verbinden. Die Führungs- und Betätigungselemente
8, 13 sind auf den Schlitten 7 bzw. 12 verschiebbar
befestigt, so dass deren Lage entlang des jeweiligen
Schlittens eingestellt werden kann. Über die
Fortsätze 9 bzw. 14 kann auch die Betätigung der Zangenöffnung
und -schliessung erfolgen. Die Führungselemente
8 bzw. 13 sind auf den Schlitten quer zur Vorschubrichtung
A einstellbar, wobei deren gegenseitige Distanz
in Figur 2 mit B bzw. B1 eingezeichnet ist. Die
Verstellung entlang des Schlittens 7 bzw. 12 erfolgt zur
Anpassung an das jeweilige Blechformat. Wie besonders gut
in Figur 2 ersichtlich, ist die erste Vorschubeinrichtung
7-10 so ausgestaltet, dass in der Übergabeposition nur
deren Greifmittel 9, 10 durch die zweite Vorschubeinrichtung
12-15 hindurchgreifen, während die Führungs- und Betätigungsmittel
8 und der Schlitten 7 der ersten Vorschubeinrichtung
in Vorschubrichtung gesehen hinter der zweiten
Vorschubeinrichtung 12-15 verbleibt. Dies erlaubt eine
einfache Einstellung des Abstandes B der Greifmittel
9, 10 der ersten Vorschubeinrichtung unabhängig von der
zweiten Vorschubeinrichtung und auch das einfache Einstellen
des Abstandes B1 zwischen den Greifmitteln 15 der
zweiten Vorschubeinrichtung. Die Einstellung dieser Abstände
B, B1 ist weiter dadurch vereinfacht, dass beide
Vorschubeinrichtungen oberhalb des Tisches 20 bzw. der
Vorschubebene angeordnet sind. Dies ergibt eine gute Zugänglichkeit
zur Einstellung bzw. Umrüstung und ferner
eine Unabhängigkeit von Durchbrüchen im Tisch 20, wie sie
bei von unten her an das Blech angreifenden Vorschubeinrichtungen
benötigt werden. Das Trageglied 6 kann dabei
durch nicht gezeigte Befestigungsmittel oberhalb desselben
oder seitlich desselben am Maschinengestell befestigt
sein.The gripping means 10 and 15 have known per se
pincer-like components, which open and
Close can be pressed to the respective sheet metal
let go or grab. The gripping means 10 and 15
also have in the conveying direction facing backwards
Fortsuits 9 and 14 on which the tongs
