Definitions

  • Sheet metal printing machines and sheet metal coating machines are used for printing or varnishing metal sheets, from which after printing and / or varnishing, cans for packaging purposes, lids for these cans or for glasses, closures for bottles or similar articles made from thin sheet metal are produced. Since the metal sheets are generally printed in multiple colors, they have to be fed to the printing press within very narrow tolerances in order to avoid an offset in the longitudinal and / or transverse direction of the individual color applications. Since a single sheet of metal usually comprises several blanks for the intended sheet metal articles and at least two narrow area strips in the area of a later solder or weld seam must remain free of paints and varnish within a blank, the varnish application must also be positioned very precisely.
  • a machine for the metal sheets is arranged on the inlet side of the machine. It has two stops, which are arranged at a certain mutual distance on the first drum of the machine in question and rotate with it.
  • the metal sheets are fed to this first machine drum by means of a feed device which is formed, for example, by a belt conveyor. Since this feed device would not ensure an exact placement on the stops of the machine drum, a pressing device is provided as a further part of the contact device, which is guided parallel to the path of movement of the sheet metal relative to the stops and which is driven by a power drive in the direction of the stops away from them is driven.
  • the drive speed of the pressing device is greater than the escape speed of the stops on the machine drum.
  • the pressing device has two pressing members, which form-fit against the rear edge of the supplied sheet metal plate and push the sheet metal plate in front of it - and finally press against the stops on the machine drum.
  • These pressing members are each connected to the pressing device by means of a resilient force transmission member, so that the metal sheets are always pressed against the stops with the same pressing force, which is independent of the force of the drive of the pressing device.
  • the application of the pressure members to the metal sheet can also be referred to as coupling and the pressure members themselves can accordingly be referred to as coupling members.

  • the object is achieved to avoid the disadvantages of the conventional application devices and in particular to reduce or eliminate the risk that the metal sheets bulge out during application and their edges may bulge.

  • the metal sheet is held in place by the adhesive element, i.e. clamped so that the risk of buckling is further reduced to a considerable extent.
  • the coupling member is coupled to the front edge of the metal sheet, it is no longer necessary to adjust the position of the coupling member to the position of the rear edge of the metal sheet when changing the length of the metal sheets.
  • the loads on the metal sheet in the area of the coupling elements are reduced by doubling the number of coupling elements. It also improves the even placement of the sheet on the stops, because now two coupling links symmetrical to the center line of the movement path act on the metal sheet.

Description

Blechtafel-Druckmaschinen und Blechtafel-Lackiermaschinen werden zum Bedrucken bzw. Lackieren von Metalltafeln eingesetzt, aus denen nach dem Bedrucken und/oder Lackieren Dosen für Verpackungszwecke, Deckel für diese Dosen oder für Gläser, Verschlüsse für Flaschen oder ähnliche aus Feinblech gefertigte Artikel hergestellt werden. Da die Blechtafeln im allgemeinen mehrfarbig bedruckt werden, müssen sie der Druckmaschine innerhalb sehr enger Toleranzen zugeführt werden, um einen Versatz in Längsrichtung und/oder Querrichtung der einzelnen Farbaufträge zu vermeiden. Da eine einzelne Blechtafel meist mehrere Zuschnitte für die vorgesehenen Blechartikel umfaßt und innerhalb eines Zuschnittes mindestens zwei schmale Flächenstreifen im Bereich einer späteren Löt- oder Schweißnaht frei von Farben und Lack bleiben müssen, muß auch der Lackauftrag sehr genau positioniert werden.Sheet metal printing machines and sheet metal coating machines are used for printing or varnishing metal sheets, from which after printing and / or varnishing, cans for packaging purposes, lids for these cans or for glasses, closures for bottles or similar articles made from thin sheet metal are produced. Since the metal sheets are generally printed in multiple colors, they have to be fed to the printing press within very narrow tolerances in order to avoid an offset in the longitudinal and / or transverse direction of the individual color applications. Since a single sheet of metal usually comprises several blanks for the intended sheet metal articles and at least two narrow area strips in the area of a later solder or weld seam must remain free of paints and varnish within a blank, the varnish application must also be positioned very precisely.

Um eine solche genaue Positionierung der Blechtafeln zu erreichen, ist auf der Einlaufseite diese Maschinen für die Blechtafeln eine Anlegeeinrichtung angeordnet. Sie weist zwei Anschläge auf, die in einem bestimmten gegenseitigen Abstand an der ersten Trommel der betreffenden Maschine angeordnet sind und mit dieser umlaufen. Dieser ersten Maschinentrommel werden die Blechtafeln mittels einer Zuführvorrichtung zugeführt, die beispielsweise durch einen Bandförderer gebildet wird. Da diese Zuführvorrichtung ein genaues Anlegen an den Anschlägen der Maschinentrommel nicht gewährleisten würde, ist als weiterer Teil der Anlageeinrichtung eine Andrückvorrichtung vorhanden, die parallel zur Bewegungsbahn der Blechtafel relativ zu den Anschlägen beweglich geführt ist und die mittels eines Kraftantriebes in Richtung auf die Anschläge hin und von ihnen weg angetrieben wird. Dabei ist die Antriebsgeschwindigkeit der Andrückvorrichtung größer als die Fluchtgeschwindigkeit der Anschläge an der Maschinentrommel.In order to achieve such precise positioning of the metal sheets, a machine for the metal sheets is arranged on the inlet side of the machine. It has two stops, which are arranged at a certain mutual distance on the first drum of the machine in question and rotate with it. The metal sheets are fed to this first machine drum by means of a feed device which is formed, for example, by a belt conveyor. Since this feed device would not ensure an exact placement on the stops of the machine drum, a pressing device is provided as a further part of the contact device, which is guided parallel to the path of movement of the sheet metal relative to the stops and which is driven by a power drive in the direction of the stops away from them is driven. The drive speed of the pressing device is greater than the escape speed of the stops on the machine drum.

Die Andrückvorrichtung weist bei herkömmlichen Anlegeeinrichtungen zwei Andrückglieder auf, die sich an der Hinterkante der zugeführten Blechtafel formschlüssig anlegen und die Blechtafel vor sich herschieben-und schließlich gegen die Anschläge an der Maschinentrommel drücken. Diese Andrückglieder sind mittels je eines nachgiebigen Kraftübertragungsgliedes mit der Andrückvorrichtung verbunden, damit die Blechtafeln an den Anschlägen stets mit der gleichen Andrückkraft angedrückt werden, die unabhängig von der Kraft des Antriebes der Andrückvorrichtung ist. Verallgemeinernd kann man das Anlegen der Andrückglieder an dar Blechtafel auch als Ankoppeln bezeichnen und die Andrückglieder selbst dementsprechend als Koppelungsglieder bezeichnen.In conventional application devices, the pressing device has two pressing members, which form-fit against the rear edge of the supplied sheet metal plate and push the sheet metal plate in front of it - and finally press against the stops on the machine drum. These pressing members are each connected to the pressing device by means of a resilient force transmission member, so that the metal sheets are always pressed against the stops with the same pressing force, which is independent of the force of the drive of the pressing device. In general, the application of the pressure members to the metal sheet can also be referred to as coupling and the pressure members themselves can accordingly be referred to as coupling members.

Die Blechtafeln aus Stahlblech oder Leichtmetallblech werden mit immer geringeren Wanddicken hergestellt und zu Blechartikeln verarbeitet. Je dünner die Blechtafeln sind, umso größer ist die Gefahr, daß durch die auf die Hinterkante der Blechtafeln einwirkende Andrückkraft die Blechtafeln hochgewölbt werden und dabei womöglich noch die Kanten eingedrückt werden. Dadurch wird jedenfalls die Anlegegenauigkeit beeinträchtigt.The sheet metal sheets made of sheet steel or light metal sheet are manufactured with ever smaller wall thicknesses and processed into sheet metal articles. The thinner the metal sheets, the greater the risk that the metal sheets will be arched up by the pressing force acting on the rear edge of the metal sheets and that the edges may still be pressed in. In any case, this impairs the accuracy of the application.

Mit der im Anspruch 1 angegebenen Anlegeeinrichtung wird die Aufgabe gelöst, die Nachteile der herkömmlichen Anlegeeinrichtungen zu vermeiden und insbesondere die Gefahr zu vermindern oder zu beseitigen, daß die Blechtafeln sich beim Anlegen aufwölben und womöglich ihre Kanten eingebeult werden.With the application device specified in claim 1, the object is achieved to avoid the disadvantages of the conventional application devices and in particular to reduce or eliminate the risk that the metal sheets bulge out during application and their edges may bulge.

Dadurch, daß als Koppelungsglied zum Koppeln der zugeführten Blechtafel mit der Andrückvorrichtung ein Haftelement verwendet wird, das in der Nachbarschaft der Anschläge der Maschinentrommel angeordnet ist und daß mittels einer Hubvorrichtung normal zur Fläche der Blechtafel an diese herangeführt wird und nur kraftschlüssig mit ihr gekoppelt wird, wird die Andrückkraft nahe der Vorderkante der Blechtafel auf diese übertragen, so daß der Abstand zwischen der Krafteinleitungsstelle und der Kraftaufnahmestelle an den Anschlägen so gering ist, daß allein schon deswegen die Gefahr des Knickens oder Aufwölbens der Blechtafel verringert ist. Außerdem wird die Blechtafel durch das Haftelement festgehalten, d.h. eingespannt, so daß die Knickgefahr in einem beträchtlichen Maße weiter verringert wird. Dadurch, daß die Vorderkante der Blechtafel sich ohne Aufwölbung des anschließenden Flächenbereiches an den Anschlägen anlegt, erfährt die Vorderkante keine Querkraft, so daß dadurch auch die Gefahr des Einbeulens der Vorderkante deutlich verringert, wenn nicht gar beseitigt ist. Für die Hinterkante der Blechtafel gilt das ohnehin, weil dort kein Andrückelement mehr wirkt.Characterized in that an adhesive element is used as a coupling member for coupling the supplied sheet metal sheet to the pressing device, which is arranged in the vicinity of the stops of the machine drum and that a lifting device is used to bring the sheet metal sheet normal to the surface thereof and to couple it only non-positively, the pressing force near the front edge of the sheet is transferred to it, so that the distance between the force introduction point and the force absorption point at the stops is so small that the risk of kinking or bulging of the sheet is reduced for this reason alone. In addition, the metal sheet is held in place by the adhesive element, i.e. clamped so that the risk of buckling is further reduced to a considerable extent. The fact that the front edge of the sheet metal lies against the stops without bulging of the adjoining surface area means that the front edge does not experience any transverse force, so that the risk of the front edge denting is also significantly reduced, if not eliminated. This applies to the rear edge of the sheet anyway, because there is no longer any pressure element.

Dadurch, daß das Koppelungsglied im Bereich der Vorderkante der Blechtafel mit dieser gekoppelt wird, ist es nicht mehr erforderlich, bei einem Wechsel der Länge der Blechtafeln die Lage des Koppelungsgliedes auf die Lage der Hinterkante der Blechtafel einzustellen.Because the coupling member is coupled to the front edge of the metal sheet, it is no longer necessary to adjust the position of the coupling member to the position of the rear edge of the metal sheet when changing the length of the metal sheets.

In den Ansprüchen 2 und 3 sind zwei zweckmäßige Ausgestaltungen für das Koppelungsglied angegeben.In claims 2 and 3, two expedient configurations for the coupling element are specified.

Bei einer Ausgestaltung nach Anspruch 4 werden durch die Verdoppelung der Zahl der Koppelungsglieder die Belastungen der Blechtafel im Bereich der Koppelungsglieder vermindert. Außerdem wird dadurch das gleichmäßige Anlegen der Blechtafel an den Anschlägen verbessert, weil jetzt zwei Koppelungsglieder symmetrisch zur Mittellinie der Bewegungsbahn auf die Blechtafel einwirken. Dadurch ist es möglich, an den Anschlägen auch solche Blechtafeln gleichmäßig anzulegen und dabei auszurichten, bei denen die Vorderkante aufgrund von Maß- und Formabweichungen im Rahmen der Fertigungstoleranzen oder infolge einer ungenauen Zuführung zunächst nicht rechtwinklig zur Bewegungsrichtung ausgerichtet ist.In an embodiment according to claim 4, the loads on the metal sheet in the area of the coupling elements are reduced by doubling the number of coupling elements. It also improves the even placement of the sheet on the stops, because now two coupling links symmetrical to the center line of the movement path act on the metal sheet. This makes it possible to evenly apply and align such metal sheets on the stops in which the front edge is initially not aligned at right angles to the direction of movement due to dimensional and shape deviations within the scope of the manufacturing tolerances or due to an inaccurate feeding.

Durch eine Ausgestaltung nach Anspruch 5 wird eine genaue Führung des Koppelungsgliedes erleichtert und, beim Vorhandensein von zwei Koppelungsglieder, deren Führung vereinfacht. Eine ähnliche Wirkung wird durch eine Ausgestaltung nach Anspruch 6 erreicht.An embodiment according to claim 5 facilitates precise guidance of the coupling element and, in the presence of two coupling elements, simplifies their guidance. A similar effect is achieved by an embodiment according to claim 6.

Durch eine Ausgestaltung nach Anspruch 7 wird ein verhältnismäßig einfach und billig herzustellendes Kraftübertragungsglied geschaffen, dessen Kraftwirkung sich auch verhältnismäßig einfach einstellen läßt. Ähnliches gilt auch für eine Ausgestaltung nach Anspruch 8.An embodiment according to claim 7 creates a relatively simple and inexpensive force transmission member, the force effect of which can also be set relatively easily. The same applies to an embodiment according to claim 8.

Bei einer Ausgestaltung nach Anspruch 8 entfällt auch bei dem sekundären Ausrichtelement das Einstellen auf die ihm zugekehrte Seitenkante der Blechtafeln, wenn deren Breite sich ändert.In an embodiment according to claim 8, the adjustment to the side edge of the metal sheets facing it also does not apply to the secondary alignment element if the width thereof changes.

Die aus Fig. 1 und Fig. 2 ersichtliche Anlegeeinrichtung 10 dient dazu, eine Blechtafel 11 von im allgemeinen rechteckigem Zuschnitt mit der Vorderkante 12 an zwei Anschlägen 13 einer Blechtafel-Druckmaschine oder einer Blechtafel-Lackiermaschine anzulegen. Diese Anschläge 13 sind an einer Trommel der betreffenden Maschine angeordnet und laufen mit dieser um. Die Blechtafel 11 wird von einer nicht dargestellten Zuführvorrichtung auf einer ebenen Bewegungsbahn zugeführt und mittels der Anlegeeinrichtung 10 an den Anschlägen 13 angelegt. Dabei ist die Annäherungsgeschwindigkeit der Blechtafel 11 größer als die Fluchtgeschwindigkeit der Anschläge 13. Diese Fluchtgeschwindigkeit der Anschläge 13 und die daraus sich ergebende absolute Annäherungsgeschwindigkeit der Blechtafel 11 wird im folgenden nach Art einer Momentaufnahme betrachtet, bei der die Anschläge 13 in Ruhe sind und bei der Blechtafel 11 und bei der Anlegeeinrichtung 10 nicht mehr deren Absolutgeschwindigkeit sondern nur noch deren Relativgeschwindigkeit und Relativbewegung gegenüber den Anschlägen 13 betrachtet wird.The application device 10 shown in FIG. 1 and FIG. 2 serves to produce a sheet metal plate 11 of generally rectangular cut with the front edge 12 at two stops 13 of a sheet metal plate printing machine or one Create a sheet metal painting machine. These stops 13 are arranged on a drum of the machine in question and rotate with it. The sheet metal plate 11 is fed from a feed device, not shown, on a flat movement path and is applied to the stops 13 by means of the application device 10. The speed of approach of the metal sheet 11 is greater than the speed of escape of the stops 13. This speed of flight of the stops 13 and the resulting absolute speed of approach of the sheet 11 is considered in the following in the manner of a snapshot in which the stops 13 are at rest and in which Sheet 11 and in the application device 10 no longer its absolute speed but only its relative speed and relative movement with respect to the stops 13 is considered.

Die Anlegeeinrichtung 10 weist als Hauptbaugruppen eine Andrückvorrichtung 14 und eine Ausrichtvorrichtung 15 auf. Die Andrückvorrichtung 14 dient zum Andrücken der Blechtafel 11 an den Anschlägen 13. Die Ausrichtvorrichtung 15 dient dazu, die Blechtafel 11 seitlich auszurichten, damit ihre in der Bewegungsrichtung gelegene Mittellinie genau auf der Sollinie liegt. Die Ausrichtvorrichtung 15 weist dafür ein primäres Ausrichtglied 16 und ein sekundäres Ausrichtglied 17 auf, das mit der in der Bewegungsrichtung links gelegenen Seitenkante 18 bzw. mit der rechts gelegenen Seitenkante 19 der Blechtafel 11 zusammenwirken.The application device 10 has a pressure device 14 and an alignment device 15 as main assemblies. The pressing device 14 serves to press the sheet metal plate 11 against the stops 13. The aligning device 15 serves to laterally align the sheet metal plate 11 so that its center line in the direction of movement lies exactly on the desired line. For this purpose, the alignment device 15 has a primary alignment member 16 and a secondary alignment member 17, which interact with the side edge 18 on the left in the direction of movement or with the side edge 19 of the metal sheet 11 on the right.

Die Andrückvorrichtung 14 wird mittels einer nicht dargestellten Führung parallel zur Bewegungsbahn der Blechtafel 11 beweglich geführt. Sie wird in Richtung auf die Anschläge 13 hin und von ihnen weg durch einen Antrieb 21 bewegt, der in Fig. 1 und Fig. 2 lediglich durch einen Doppelpfeil symbolisch angedeutet ist. Die Andrückvorrichtung 14 weist zum Ankoppeln an der Blechtafel 11 zwei Koppelunsglieder auf, die beide als Saugnapf 22 und 23 ausgebildet sind. Anstelle der Saugnäpfe können die Koppelungsglieder auch durch Elektromagneten gebildet werden.The pressing device 14 is guided to be movable parallel to the movement path of the sheet metal plate 11 by means of a guide, not shown. It is moved in the direction of the stops 13 and away from them by a drive 21 which is symbolically indicated in FIG. 1 and FIG. 2 only by a double arrow. The pressing device 14 has two coupling members for coupling to the metal sheet 11, both of which are suction cups 22 and 23 are trained. Instead of the suction cups, the coupling members can also be formed by electromagnets.

Jeder der Saugnäpfe 22 und 23 ist mit einer Hubvorrichtung 24, zweckmäßigerweise in Form eines pneumatischen Kolbenantriebes, verbunden, die beide an einem gemeinsamen Träger 25 angeordnet sind. Dieser Träger 25 ist an einer Führung 26 der Andrückvorrichtung 14 parallel zur Bewegungsbahn der Blechtafel 11 beweglich geführt, was in Fig. 1 durch den Doppelpfeil 27 veranschaulicht wird. Zwischen dem Träger 25 und der Andrückvorrichtung 14 wirken zwei Schraubenfedern 28 und 29 als nachgiebiges Kraftübertragungsglied, durch das nach der Anlage der Vorderkante 12 der Blechtafel 11 an den Anschlägen 13 eine bestimmte einstellbare Andrückkraft auf die Blechtafel 11 ausgeübt wird.Each of the suction cups 22 and 23 is connected to a lifting device 24, expediently in the form of a pneumatic piston drive, both of which are arranged on a common carrier 25. This carrier 25 is movably guided on a guide 26 of the pressing device 14 parallel to the path of movement of the sheet metal plate 11, which is illustrated in FIG. 1 by the double arrow 27. Between the carrier 25 and the pressing device 14, two helical springs 28 and 29 act as a flexible force transmission member, by means of which a certain adjustable pressing force is exerted on the metal plate 11 after the front edge 12 of the metal plate 11 has made contact with the stops 13.

Die Andrückvorrichtung 14 ist im übrigen so ausgebildet und angeordnet, daß beim Ankoppeln an der Blechtafel 11 ihre Koppelungsglieder 22 und 23 so weit wie möglich in der Nachbarschaft der Vorderkante 12 der Blechtafel 11 und damit auch in der Nachbarschaft der Verbindungslinie der Anschläge 13 gelegen sind.The pressing device 14 is otherwise designed and arranged so that when coupling to the sheet 11 their coupling members 22 and 23 are as far as possible in the vicinity of the front edge 12 of the sheet 11 and thus also in the vicinity of the connecting line of the stops 13.

Das primäre Ausrichtglied 16 ist mit einer Positioniervorrichtung 31 verbunden. Dabei ist das Ausrichtglied 16 in der Bewegungsrichtung der Blechtafel 11 unverschieblich und quer zur Bewegungsrichtung der Blechtafel 11 mittels nicht dargestellter Führungselemente verschiebbar geführt. Die Positioniervorrichtung 31 weist zwei miteinander zusammenwirkende Anschlagteile 32 und 33 auf. Das eine Anschlagteil 32 ist mit dem Ausrichtglied 16 starr verbunden. Das andere Anschlagteil 33 ist relativ zur Bewegungsbahn der Blechtafel 11 auf einen vorgegebenen Abstand einstellbar ausgebildet. Die Positioniervorrichtung 31 weist außerdem einen doppeltwirkenden Kraftantrieb 34 mit zwei bestimmten Endstellungen auf. Er ist über ein nachgiebiges Kraftübertragungsglied 35 mit dem Ausrichtglied 16 verbunden.The primary alignment member 16 is connected to a positioning device 31. The aligning member 16 is guided in the direction of movement of the sheet metal plate 11 so that it cannot move and can be moved transversely to the direction of movement of the sheet metal plate 11 by means of guide elements (not shown). The positioning device 31 has two mutually cooperating stop parts 32 and 33. One stop part 32 is rigidly connected to the alignment member 16. The other stop part 33 is designed to be adjustable to a predetermined distance relative to the movement path of the metal sheet 11. The positioning device 31 also has a double-acting power drive 34 with two specific end positions. It is connected to the alignment member 16 via a resilient force transmission member 35.

In seinem einen Betriebszustand zieht der Antrieb 34 das Ausrichtglied 16 in eine Bereitschaftsstellung zurück, in der das Ausrichtglied 16 sich außerhalb der Bewegungsbahn der Blechtafel 11 befindet, damit diese der Anlegeeinrichtung 10 ungehindert zugeführt werden kann. In seinem anderen Betriebszustand verschiebt der Kraftantrieb 34 über das Kraftübertragungsglied 35 das Ausrichtglied 16 in Richtung auf die Bewegungsbahn der Blechtafel 11 hin, bis die beiden Anschlagteile 32 und 33 aufeinandertreffen. Damit ist das Ausrichtglied 16 in seiner Betriebsstellung positioniert, in der es sich genau an der Sollstelle des linken Seitenrandes 18 der Blechtafel 11 befindet. Sofern die Blechtafel 11 der Anlegeeinrichtung 10 auf einer Bewegungsbahn zugeführt wurde, die jenseits der Sollstelle näher bei der Positioniervorrichtung 31 gelegen ist, wird die Blechtafel 11 vom Ausrichtglied 16 bis zur Sollstelle seitlich verschoben, sobald der Antrieb 34 eingeschaltet wird.In its one operating state, the drive 34 pulls the alignment member 16 back into a standby position, in which the alignment member 16 is outside the path of movement of the sheet metal plate 11 so that it can be fed to the application device 10 unhindered. In its other operating state, the power drive 34 moves the alignment member 16 in the direction of the path of movement of the metal sheet 11 via the power transmission member 35 until the two stop parts 32 and 33 meet. The alignment member 16 is thus positioned in its operating position, in which it is located exactly at the desired position of the left side edge 18 of the metal sheet 11. If the sheet metal plate 11 has been fed to the application device 10 on a movement path which is located closer to the positioning device 31 beyond the set point, the sheet metal plate 11 is laterally displaced from the alignment member 16 to the set point as soon as the drive 34 is switched on.

Das sekundäre Ausrichtglied 17 ist ebenfalls mit einer Positioniervorrichtung 36 verbunden. Dabei ist das Ausrichtglied 17 ebenfalls mittels einer nicht dargestellten Führung in der Bewegungsrichtung der Blechtafel 11 unverschieblich und quer dazu verschiebbar geführt. Die Positioniervorrichtung 36 weist einen doppeltwirkenden Kraftantrieb 37 mit zwei bestimmten Endstellungen auf. Er ist über ein nachgiebiges Kraftübertragungsglied 38 mit dem Ausrichtglied 17 verbunden. Die Positioniervorrichtung 36 weist für das Ausrichtglied 17 keine Anschlagteile auf. Der Kraftantrieb 37 ist jedoch innerhalb der Positioniervorrichtung 36 in einem gewissen Bereich in Richtung auf die Bewegungsbahn der Blechtafel 11 hin und von dieser weg einstellbar ausgebildet, damit das Kraftübertragungsglied 38 auf eine bestimmten Andrückkraft eingestellt werden kann, mit der es auf eine in der Anlegeeinrichtung 10 befindliche Blechtafel 11 einwirkt. Diese Kraft des Kraftübertragungsgliedes 38 ist in jedem Falle kleiner als die Kraft des Kraftübertragungsgliedes 35 der Positioniervorrichtung 31.The secondary alignment member 17 is also connected to a positioning device 36. The alignment member 17 is also guided by means of a guide, not shown, in the direction of movement of the sheet metal plate 11 so that it cannot move and can be moved transversely thereto. The positioning device 36 has a double-acting power drive 37 with two specific end positions. It is connected to the alignment member 17 via a resilient force transmission member 38. The positioning device 36 has no stop parts for the alignment member 17. However, the power drive 37 is configured within the positioning device 36 in a certain range in the direction of the movement path of the sheet metal plate 11 and away from it, so that the force transmission member 38 can be set to a specific pressing force with which it is applied to one in the application device 10 located sheet metal plate 11 acts. In any case, this force of the force transmission element 38 is smaller than the force of the force transmission element 35 of the positioning device 31.

In seinem einen Betriebszustand zieht der Antrieb 37 das Ausrichtglied 17 in eine Bereitschaftsstellung zurück, in der es außerhalb der Bewegungsbahn der Blechtafel 11 gelegen ist. In seinem anderen Betriebszustand drückt der Antrieb das Ausrichtglied 17 in seine Betriebsstellung, in der es an der rechten Seitenkante 19 der in der Anlegeeinrichtung befindlichen Blechtafel 11 anliegt. Sofern die Blechtafel 11 der Anlegeeinrichtung 16 auf einer Bewegungsbahn zugeführt wurde, bei der ihre rechte Seitenkante 19 jenseits der Sollstelle näher bei der Positioniervorrichtung 36 gelegen ist, wird die Blechtafel 11 vom Ausrichtglied 17 seitlich verschoben, bis ihre linke Außenkante 18 an dem in seiner Betriebsstellung befindlichen Ausrichtglied 16 anliegt.In its one operating state, the drive 37 pulls the alignment member 17 back into a standby position, in which it is located outside the path of movement of the metal sheet 11. In its other operating state, the drive presses the alignment member 17 into its operating position, in which it rests on the right side edge 19 of the sheet metal plate 11 located in the application device. If the sheet 11 has been fed to the application device 16 on a movement path in which its right side edge 19 is located closer to the positioning device 36 beyond the desired location, the sheet 11 is laterally displaced by the aligning member 17 until its left outer edge 18 on the in its operating position Alignment member 16 is present.

Im folgenden werden anhand Fig. 3 - Fig. 5 abgewandelte Ausführungsformen der Anlegeeinrichtung erläutert. Die Abwandlung betrifft die Art und die Anordnung der Ausrichtvorrichtung für das seitliche Ausrichten der Blechtafel 11. Die dabei verwendete Andrückvorrichtung ist weitestgehend gleich der Andrückvorrichtung 14, weshalb in soweit auf die diesbezüglichen Erläuterungen anhand Fig. 1 und Fig. 2 verwiesen wird. Soweit Teile der abgewandelten Ausrichtvorrichtungen mit den entsprechenden Teilen der Ausrichtvorrichtung 15 gleich oder zumindest ähnlich sind, wird auch in soweit auf die vorangehenden Erläuterungen verwiesen.Modified embodiments of the application device are explained below with reference to FIGS. 3-5. The modification relates to the type and arrangement of the alignment device for the lateral alignment of the sheet metal plate 11. The pressure device used here is largely the same as the pressure device 14, which is why reference is made in so far to the relevant explanations with reference to FIGS. 1 and 2. Insofar as parts of the modified alignment devices are identical or at least similar to the corresponding parts of the alignment device 15, reference is also made to the above explanations.

Bei der Anlegeeinrichtung 40 nach Fig. 3 ist das primäre Ausrichtglied 41 und dessen Positioniervorrichtung 42 gleich dem Ausrichtglied 16 und der Positioniervorrichtung 31 (Fig. 2) ausgebildet und angeordnet.In the application device 40 according to FIG. 3, the primary alignment member 41 and its positioning device 42 are designed and arranged in the same way as the alignment member 16 and the positioning device 31 (FIG. 2).

der Andrückvorrichtung 14, sobald die Koppelungsglieder 22 und 23 an der Blechtafel 11 angekoppelt sind. Diese Koppelungsglieder in Form der Saugnäpfe 22 und 23 sind über je eine Hubvorrichtung mit dem Träger 25 verbunden. Für die Verwendung auch als Ausrichtglied ist die Führung 26 des Trägers 25 so ausgebildet, daß sie eine Relativbewegung des Trägers 25 gegenüber der Andrückvorrichtung nicht nur parallel zur Bewegungsbahn der Blechtafel 11 sondern auch quer dazu zuläßt. In gleicher Weise sind die nachgiebigen Übertragungsglieder 28 und 29 ebenfalls so ausgebildet und angeordnet, daß sie eine Querbewegung des Trägers 25 ermöglichen.the pressing device 14 as soon as the coupling members 22 and 23 are coupled to the metal sheet 11. These coupling members in the form of the suction cups 22 and 23 are each connected to the carrier 25 via a lifting device. For use as an alignment member, the guide 26 of the carrier 25 is designed so that it has a relative movement of the carrier 25 relative to the pressing device not only allows parallel to the path of movement of the sheet metal plate 11 but also transversely thereto. In the same way, the resilient transmission members 28 and 29 are also designed and arranged so that they allow a transverse movement of the carrier 25.

Dieses sekundäre Ausrichtglied 43 ist mit der Positioniervorrichtung 44 verbunden, die weitgehend gleich der Positioniervorrichtung 36 (Fig. 2) ausgebildet ist. Die Positioniervorrichtung 44 ist mittels eines Bügels 45 mit der Andrückvorrichtung 14 starr verbunden, so daß sie deren Relativbewegung beim Andrücken der Blechtafel 11 an die Anschläge 13 in beiden Richtungen mitmacht.This secondary alignment member 43 is connected to the positioning device 44, which is largely identical to the positioning device 36 (FIG. 2). The positioning device 44 is rigidly connected to the pressing device 14 by means of a bracket 45, so that it takes part in its relative movement when the sheet metal plate 11 is pressed against the stops 13 in both directions.

Bei der Positioniervorrichtung 44 sind der Antrieb 46 und das nachgiebige Kraftübertragungsglied 47 so angeordnet und ausgebildet, daß im einen Betriebszustand des Antriebes 46 das Ausrichtglied 43 aus seiner Ruhelage um ein gewisses Maß seitlich von dem primären Ausrichtglied 41 weggezogen ist und daß es im anderen Betriebszustand des Antriebes 46, bei Abwesenheit einer Blechtafel 11, um etwa das gleiche Maß über seine Ruhestellung hinaus in Richtung auf das primäre Ausrichtglied 41 hin verschoben ist. Dadurch wird sichergestellt, daß eine möglicherweise gegenüber ihrer Sollstellung nach rechts versetzt zugeführte Blechtafel 11 gegen das in seiner Betriebsstellung stehende primäre Ausrichtglied 41 verschoben wird. Bei einer nach links versetzt zugeführten Blechtafel 11 fängt das sekundäre Ausrichtglied 43 mit seiner Positioniervorrichtung 44 die seitliche Verschiebebewegung der Blechtafel 11 auf, die von dem primären Ausrichtglied 41 und dessen Positioniervorrichtung 42 ausgelöst wird.In the positioning device 44, the drive 46 and the resilient force transmission member 47 are arranged and designed such that, in one operating state of the drive 46, the alignment member 43 is pulled to a certain extent laterally away from the primary alignment member 41 from its rest position and that it is in the other operating state of the Drive 46, in the absence of a sheet metal plate 11, is displaced by approximately the same amount beyond its rest position in the direction of the primary alignment member 41. This ensures that a sheet metal plate 11 which is possibly displaced to the right relative to its desired position is displaced against the primary aligning member 41 which is in its operating position. In the case of a sheet metal plate 11 which is displaced to the left, the secondary aligning member 43, with its positioning device 44, absorbs the lateral displacement movement of the sheet metal plate 11, which is triggered by the primary aligning member 41 and its positioning device 42.

Bei der aus Fig. 4 ersichtlichen Anlegeeinrichtung 50 ist das primäre Ausrichtglied 51 und seine Positioniervorrichtung 52 wie das Ausrichtglied 41 bzw. die Positioniervorrichtung 42 ausgebildet und angeordnet (Fig. 3). Als sekundäres Ausrichtglied 53 dienen wiederum die Koppelungsgieder 22 und 23 am Träger 25 der Andrückvorrichtung 14. Die Positioniervorrichtung 54 wird durch das nachgiebige Kraftübertragungsglied 55 gebildet, das sich an einem Halter 56 abstützt, der mittels des Bügels 57 mit der Andrückvorrichtung 14 starr verbunden ist.4, the primary alignment member 51 and its positioning device 52 are like the alignment member 41 or the positioning device 42 formed and arranged (Fig. 3). The coupling members 22 and 23 on the carrier 25 of the pressing device 14 in turn serve as secondary alignment members 53. The positioning device 54 is formed by the flexible force transmission member 55, which is supported on a holder 56 which is rigidly connected to the pressing device 14 by means of the bracket 57.

Bei der Anlegeeinrichtung 50 wird unterstellt, daß die Blechtafel 11 gegenüber ihrer Sollstellung in Richtung auf das primäre Ausrichtglied 51 hin seitlich versetzt zugeführt wird und anschließend von der Positioniervorrichtung 52 in ihre Sollstellung verschoben wird, wobei diese Bewegung von der Positioniervorrichtung 54 und ihrem Kraftübertragungsglied 55 abgefangen wird.In the application device 50, it is assumed that the sheet metal plate 11 is fed laterally offset in relation to its desired position in the direction of the primary alignment member 51 and is then shifted into its desired position by the positioning device 52, this movement being intercepted by the positioning device 54 and its force transmission member 55 becomes.

Bei der aus Fig. 5 ersichtlichen Anlegeeinrichtung 60 ist das primäre Ausrichtglied 61 unverschieblich mit einem Halter 62 verbunden, der seinerseits quasi ortsfest angeordnet ist. Das bedeutet, daß er zwar auf eine unterschiedliche Breite der Blechtafeln 11 eingestellt werden kann, daß er aber während des Betriebes der Anlegeeinrichtung 60 keine Bewegungen ausführt. Das sekundäre Ausrichtglied 63 und ihre Positioniervorrichtung 64 sind gleich dem Ausrichtglied 43 und dessen Positioniervorrichtung 44 ausgebildet.In the application device 60 shown in FIG. 5, the primary alignment member 61 is immovably connected to a holder 62, which in turn is arranged virtually stationary. This means that although it can be set to a different width of the metal sheets 11, it does not make any movements during the operation of the application device 60. The secondary alignment member 63 and its positioning device 64 are designed in the same way as the alignment member 43 and its positioning device 44.

Bei der Anlegeeinrichtung 60 wird unterstellt, daß die Blechtafel 11 gegenüber ihrer Sollstellung nach rechts versetzt zugeführt wird und vom sekundären Ausrichtglied 63 und seiner Positioniervorrichtung 64 bis zur Anlage an dem primären Ausrichtglied 61 zu diesem hin verschoben wird.In the application device 60 it is assumed that the sheet metal plate 11 is displaced to the right relative to its desired position and is displaced from the secondary alignment member 63 and its positioning device 64 until it abuts the primary alignment member 61.
