Description

Die Erfindung betrifft eine Transporteinrichtung zum Transportieren von insbesondere großflächigen Teilen vorzugsweise in einer Großteil-Stufenpresse (GT-Presse) nach dem Oberbegriff des Anspruchs 1.The invention relates to a transport device for transporting, in particular, large-area parts, preferably in a large-part step press (GT press) according to the preamble of claim 1.

Stand der Technik:State of the art:

Die Transporteinrichtungen zum Transportieren von großflächigen Teilen oder auch Doppelteilen bestehen aus zwei in Transportrichtung verlaufenden, einen Vertikalhub ausführenden Tragschienen, an denen an längsverfahrbaren Transportwagen befestigte und quer zur Transportrichtung angeordnete Quertraversen vorgesehen sind, die beispielsweise mit Saugern oder sonstigen Greifern bestückt sind, durch welche die Preßteile von einer Bearbeitungsstufe zur nächstfolgenden transportiert werden (DE 38 43 975 C1). Bei derartigen Fressen ist es bisweilen erforderlich, auch großflächige Karosserieteile, wie z. B. Seitenteile oder dgl. herzustellen, wobei das Werkstück aus bearbeitungstechnischen Gründen schräg im Werkzeug angeordnet ist. Durch die schräge Lage des Werkstücks ergeben sich beim Transportieren des Werkstücks in dieser Schräglage Probleme, da eine wesentlich größere Transporthöhe aufgrund der Schräglage überwunden werden muß. Damit eine Kollision mit dem Unterwerkzeug bzw. der Ablegestufe oder Leerstufe beim Ein- oder Austragen der Werkstücke vermieden wird, muß ein großer Hebehub der Quertraverse verwendet werden. Dies hat den Nachteil, daß größere Beschleunigungen beim Heben und beim Senken der Teile erforderlich sind und eine schlechtere Freigängigkeit im Bezug zum Oberwerkzeug vorliegt.The transport devices for transporting large-area parts or double parts consist of two, running in the transport direction, a vertical stroke carrying rails on which are attached to longitudinally movable trolleys and arranged transversely to the direction of transport, which are equipped, for example, with suction cups or other grippers, through which the pressed parts are transported from one processing stage to the next (DE 38 43 975 C1). With such feed, it is sometimes necessary to also large body parts, such as. B. to produce side parts or the like. The workpiece is arranged obliquely in the tool for machining reasons. Due to the inclined position of the workpiece, problems arise when transporting the workpiece in this inclined position, since a much greater transport height has to be overcome due to the inclined position. A large lifting stroke of the cross-beam must be used to avoid a collision with the lower tool or the lay-down or empty step when inserting or removing the workpieces. This has the disadvantage that greater accelerations when lifting and lowering the parts are required and there is less freedom of movement in relation to the upper tool.

Um den Hebehub oder auch Absenkhub verkleinern zu können, müssen die Werkstücke beim Ein- bzw. Austragen aus dem Werkzeugraum oder aus der Leerstufe und beim Transportieren zwischen den Stufen in eine möglichst waagerechte Lage geschwenkt werden, damit die oben genannten Nachteile beseitigt werden.In order to be able to reduce the lifting stroke or lowering stroke, the workpieces must be swiveled as horizontally as possible when carrying them in and out of the tool space or from the empty step and when transporting them between the steps, so that the disadvantages mentioned above are eliminated.

Aus der DE 38 43 975 C1 ist bereits eine Schwenkvorrichtung für die Quertraversen zur Veränderung der Schräglage, d. h. zur Lageveränderung der Werkstücke bekannt geworden, bei welcher ein mit der Quertraverse verbundener Schwenkarm über einen Servo-Motorantrieb angetrieben wird. Für eine derartige Anordnung wird eine Steuerung benötigt, die die elektrisch gesteuerten Bewegungen mit den mechanisch gesteuerten Bewegungen der Tragschienen bzw. der Quertraversen in Einklang bringt. Eine solche Steuerung ist aufwendig und kompliziert. Darüber hinaus erfordert das Plazieren der Vielzahl von Antriebsmotoren auf den zugehörigen Antriebswagen Platz und bringt Massenträgheitsprobleme mit sich.DE 38 43 975 C1 has already disclosed a swivel device for the crossbeams for changing the inclined position, ie for changing the position of the workpieces, in which a swivel arm connected to the crossbeam is used a servo motor drive is driven. A control is required for such an arrangement, which brings the electrically controlled movements into harmony with the mechanically controlled movements of the mounting rails or the cross members. Such control is complex and complicated. In addition, placing the large number of drive motors on the associated drive car requires space and brings with it inertia problems.

Aus der älteren, nicht vorveröffentlichten EP-A-499 901 ist eine Transporteinrichtung zum Transportieren von insbesondere großflächigen Teilen in einer Großteil-Stufenpresse bekannt geworden, bei welcher zwei, wenigstens eine Vertikalbewegung ausführende Tragschienen vorgesehen sind, an denen um ihre Längsachse verdrehbare und gegebenenfalls längsverfahrbare Quertraversen für den Teiletransport befestigt sind. Die Drehbewegung der Quertraversen erfolgt mittels jeweils isoliert antreibbaren Antriebsmittel. Dies stellt einen hohen technischen Aufwand dar, bei dem insbesondere auch Synchronisationsprobleme auftreten können.From the older, not previously published EP-A-499 901, a transport device for transporting particularly large parts in a large-part press has become known, in which two, at least one vertical movement carrying rails are provided, on which rotatable about their longitudinal axis and possibly longitudinally Crossbars are attached for parts transport. The rotary movement of the crossbeams takes place by means of drive means which can each be driven in isolation. This represents a high technical outlay, in which synchronization problems in particular can also occur.

Vorteile der Erfindung:Advantages of the invention:

Die erfindungsgemäße Transporteinrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß eine mechanische und gemeinsame Zwangssteuerung der Quertraversen zur Veränderung der Schräglage der Werkstücke erzielt wird. Dabei werden jeweils gleichwirkende Quertraversen über einen Schwenkmechanismus von einer gemeinsamen Schubstange angetrieben, wobei der Gesamtantrieb der auf Transportwagen längsverschiebbaren Quertraversen und der Antrieb für die Verdrehung der Quertraversen über das gemeinsame Kurvengetriebe erfolgt.The transport device according to the invention with the characterizing features of claim 1 has the advantage that a mechanical and common positive control of the crossbeams for changing the inclined position of the workpieces is achieved. In this case, cross beams with the same effect are driven by a common push rod via a swivel mechanism, the overall drive of the longitudinally displaceable on trolleys Crossbeams and the drive for the rotation of the crossbeams via the common cam mechanism.

Dies ergibt eine massenarme und damit beschleunigungsunproblematische mechanische Gesamtanordnungen, die sich auch steuerungstechnisch vorteilhaft vom Stand der Technik abhebt.This results in a low-mass and therefore acceleration-unproblematic overall mechanical arrangement, which is also advantageous in terms of control technology from the prior art.

In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen des im Hauptanspruch angegebenen Grundgedankens angegeben.Advantageous and expedient developments of the basic idea specified in the main claim are specified in the subclaims.

Die Einzelheiten der Erfindung sowie deren vorteilhafte Ausgestaltung sind in den Zeichnungen dargestellt und in der nachfolgenden Beschreibung der Erfindung näher erläutert.The details of the invention and its advantageous embodiment are shown in the drawings and explained in more detail in the following description of the invention.

Der Antrieb der Vertikalbewegung der Tragschienen 17, 17a erfolgt über ein nicht näher dargestelltes Hebel- und Schubstangengetriebe in Verbindung mit einem Kurvengetriebe 18, 18a (Fig. 4) in an sich bekannter Weise.As can also be seen from FIGS. 1 to 3, two laterally arranged support rails 17, 17a lead through the two press stages and are fastened to guide columns 14 to 16 mounted in a vertically movable manner in the empty stages 9 to 11. The vertical movement of the mounting rails 17, 17a is driven via a lever and push rod gear (not shown in more detail) in connection with a cam gear 18, 18a (FIG. 4) in a manner known per se.

An den die Presse längs durchlaufenden Tragschienen 17, 17a sind Führungsleisten 17b, 17c vorgesehen, an welchen die Transportwagen 19 bis 24 bzw. 19a bis 24a längsverfahrbar gelagert sind (s. auch Fig. 5).

Im vorderen Teil der ersten Bearbeitungsstufe dient der zusätzliche Transportwagen 20, 20a zur Führung dieser jeweils seitlich angeordneten Schubstange 29, 29a. Die Verbindung der beiden Schubstangen 29, 29a mit den in Fig. 1 und 4 dargestellten Vorschubkurven 32, 32a eines Kurvengetriebes erfolgt über jeweils eine seitlich angeordnete Pleuelstange 30, 30a sowie nachgeschalteten Rollenhebeln 31, 31a (s. Fig. 1 und 4).The transport carriages 21, 21a in the first processing stage (tools 3, 5) and the transport carriages 23, 23a in the second processing stage (tools 4, 6) with the respective discharge crossbeams 25, 26 are each mounted on laterally arranged, common push rods 29, 29a attached. In the front part of the first processing stage, the additional transport carriage 20, 20a serves to guide these push rods 29, 29a, which are arranged laterally. The connection of the two push rods 29, 29a with the feed curves 32, 32a of a cam mechanism shown in FIGS. 1 and 4 takes place via a connecting rod 30, 30a arranged laterally as well as downstream roller levers 31, 31a (see FIGS. 1 and 4).

Gleichermaßen sind die Transportwagen 22, 22a sowie 24, 24 a für die Eintrage-Quertraversen 27, 28 in den beiden Leerstufen 10, 11 ebenfalls über jeweils eine seitlich angeordnete Schubstange 33, 33a für eine gemeinsame Bewegung miteinander verbunden. Im vorderen Bereich der Presse sind die Schubstangen 33, 33a wiederum über die beiden zusätzlichen Transportwagen 19, 19a geführt. Die Wirkverbindung zu den Vorschubkurven 36, 36a im Kurvengetriebe 58, 58a erfolgt wiederum über zusätzliche Pleuelstangen 34, 34a mit nachgeschalteten Rollenhebeln 35, 35a.Similarly, the trolleys 22, 22a and 24, 24 a for the crossbars 27, 28 in the two empty stages 10, 11 are also connected to one another via a laterally arranged push rod 33, 33a for a common movement. In the front area of the press, the push rods 33, 33a are in turn guided over the two additional transport carriages 19, 19a. The operative connection to the feed curves 36, 36a in the cam mechanism 58, 58a is in turn carried out via additional connecting rods 34, 34a with downstream roller levers 35, 35a.

Alle Austrage-Quertraversen 25, 26 sowie alle Eintrage-Quertraversen 27, 28 werden demnach jeweils gemeinsam über zugehörige Schubstangen gesteuert.All discharge crossbeams 25, 26 and all entry crossbeams 27, 28 are accordingly controlled jointly via associated push rods.

Die Quertraversen 25 bis 28, die mittels Transportwagen 21 bis 24 verfahrbar sind, sind mittels eines Schwenkmechanismuses zum Verdrehen der Quertraversen um ihre Längsachse im Transportwagen drehbar gelagert. Dabei erfolgt die Drehbewegung der Quertraversen mittels an ihren Stirnseiten separat antreibbare Schwenkhebel 37, 37a für die Quertraverse 25 bzw. mittels Schwenkhebel 38, 38a für die Quertraverse 26.The crossbeams 25 to 28, which can be moved by means of transport carriages 21 to 24, are rotatably mounted in the transport carriage by means of a swivel mechanism for rotating the crossbeams about their longitudinal axis. The rotary movement of the crossbeams takes place by means of pivot levers 37, 37a for the crossbeam 25 which can be driven separately on their end faces or by means of pivoting levers 38, 38a for the crossbeam 26.

Gleichermaßen ist ein Schwenkhebel 39, 39a für die Verdrehung der Quertraverse 27 sowie ein Schwenkhebel 40, 40a für die Verdrehung der Quertraverse 28 vorgesehen. Wie aus den Figuren 5 bis 7 ersichtlich, besteht der Schwenkmechanismus für jede Quertraverse 25 bis 28 aus einer Art Wippelagerung innerhalb jedes Transportwagens 21 bis 24. Hierfür sind die Quertraversen 25 bis 28 an ihren jeweiligen Stirnseiten jeweils über einen Querbalken 85 und über zwei Absteckbolzen 60, 60a mit einem Schwenkgehäuse 86 verbunden, welches an seiner unteren Seite die jeweiligen Schwenkhebel 37 bis 40 bzw. 37a bis 40a trägt, wobei eine Zentralachse 81 zur Lagerung der wippenförmigen Anordnung dient (s. Figuren 5 und 6). Die Lagerung des Schwenkhebels 37 bis 40 und der Quertraversen 25 bis 28 über die Zentralachse 81 erfolgt über Kugellager 82. Die Zentralachse 81 ist in den Seitenwandungen 83, 83a des jeweiligen Transportwagens 21 bis 24 gelagert. Das Schwenkhebelsystem zur Verdrehung der Quertraverse 25 bis 28 um ihre Längsachse 84 besteht demnach im wesentlichen aus dem wippenförmigen Querbalken 85, an welchem die Quertraverse befestigt ist und der seinerseits über die Absteckbolzen 60, 60a am Schwenkgehäuse 86 befestigt ist. Das Schwenkgehäuse 86 ist durch die Schwenkhebel 37 bis 40 bzw. 37a bis 40a nach unten hin verlängert und über die Zentralachse 81 mittels Kugellager 82 in dem jeweiligen Transportwagen schwenkbar oder drehbar gelagert.Likewise, a pivot lever 39, 39a is provided for rotating the crossbar 27 and a pivoting lever 40, 40a for rotating the crossbar 28. As can be seen from FIGS. 5 to 7, the swivel mechanism for each crossbar 25 to 28 consists of a type of rocker bearing within each transport carriage 21 to 24. For this purpose, the crossbars 25 to 28 are each provided with a crossbeam 85 and two locking bolts 60 on their respective ends , 60a connected to a swivel housing 86 which carries the respective swivel levers 37 to 40 or 37a to 40a on its lower side, a central axis 81 serving to support the rocker-shaped arrangement (see FIGS. 5 and 6). The pivot lever 37 to 40 and the crossbeams 25 to 28 are supported via the central axis 81 via ball bearings 82. The central axis 81 is mounted in the side walls 83, 83a of the respective transport carriage 21 to 24. The pivot lever system for rotating the crossbar 25 to 28 about its longitudinal axis 84 accordingly essentially consists of the rocker-shaped crossbar 85, to which the crossbar is fastened and which in turn is fastened to the swivel housing 86 via the locking bolts 60, 60a. The swivel housing 86 is extended downwards by the swivel levers 37 to 40 or 37a to 40a and is pivotably or rotatably mounted on the central axis 81 by means of ball bearings 82 in the respective transport carriage.

Der Antrieb der beiden Schwenkhebel 37, 37a für die Quertraverse 25 bzw. der Schwenkhebel 38, 38a für die Quertraverse 26 erfolgt über jeweils eine gemeinsame Schubstange 41 bzw. 41a (s. Figuren 1 und 5). Über die zusätzlichen Führungshebel 42, 42a stehen die Schubstangen 41, 41a über die Pleuelstangen 43, 43a, die Winkelhebel 44, 44a sowie die Schubstangen 45, 45a und die Rollenhebel 46, 46a mit den Schwenkkurven 47, 47a des Kurvengetriebes in Wirkverbindung (s. Figuren 1 und 4).The two swivel levers 37, 37a for the crossbar 25 and the swivel levers 38, 38a for the crossbar 26 are driven via a common push rod 41 and 41a (see FIGS. 1 and 5). Via the additional guide levers 42, 42a, the push rods 41, 41a are operatively connected to the pivoting curves 47, 47a of the cam mechanism via the connecting rods 43, 43a, the angle levers 44, 44a and the push rods 45, 45a and the roller levers 46, 46a (see. Figures 1 and 4).

Gleichermaßen stehen wiederum die Schwenkhebel 39, 39a bzw. 40, 40a für die beiden Quertraversen 27, 28 in den Leerstufen 10, 11 in Verbindung mit einer jeweils seitlich angeordneten Schubstange 48, 48a (s. Figuren 1 und 5). Diese Schubstangen 48, 48a stehen wiederum in Wirkverbindung mit den zugehörigen Schwenkkurven 54, 54a des Kurvengetriebes, was über die Führungshebel 49, 49a, die Pleuelstangen 50, 50a, die Winkelhebel 51, 51a, die Schubstangen 52, 52a sowie die Rollenhebel 53, 53a erfolgt.Similarly, the swivel levers 39, 39a and 40, 40a for the two cross members 27, 28 in the empty stages 10, 11 are connected to a push rod 48, 48a arranged on the side (see FIGS. 1 and 5). These push rods 48, 48a are in turn in operative connection with the associated pivoting curves 54, 54a of the cam mechanism, which is done via the guide levers 49, 49a, the connecting rods 50, 50a, the angle levers 51, 51a, the push rods 52, 52a and the roller levers 53, 53a he follows.

Wie zuvor beschrieben, erfolgt demnach sowohl der gemeinsame Antrieb der Transportwagen 21, 23 für die Austrage-Quertraversen 25, 26 über die gemeinsame Schubstange 29 als auch der Transport der Transportwagen 22, 24 für die Eintrage-Quertraversen 27, 28 über die gemeinsame Schubstange 33.As previously described, both the transport carriages 21, 23 for the discharge crossbars 25, 26 are driven jointly via the common push rod 29 and the transport carriages 22, 24 for the entry crossbars 27, 28 are transported via the common push rod 33 .

Gleichermaßen erfolgt der zugehörige Antrieb für die Verdrehbewegung der Austrage-Quertraversen 25, 26 über die zugehörigen Schwenkhebel 37, 38 über die gemeinsame Schubstange 41 und der Antrieb für die Drehbewegung der Eintrage-Quertraversen 27, 28 über die zugehörigen Schwenkhebel 39, 40 über die Schubstange 48.Likewise, the associated drive for the rotational movement of the discharge cross members 25, 26 via the associated pivot levers 37, 38 via the common push rod 41 and the drive for the rotational movement of the entry cross members 27, 28 via the associated pivot levers 39, 40 via the push rod 48.

Hierdurch können demnach alle Bewegungen der Austrage-Quertraversen gemeinsam und alle Bewegungen der Eintrage-Quertraversen ebenfalls gemeinsam sowohl in ihrer Linearbewegung als auch in ihrer Verdrehbewegung separat gesteuert werden.As a result, all movements of the discharge crossbeams can be controlled jointly and all movements of the entry crossbeams can also be controlled separately both in their linear movement and in their rotational movement.

Die in der Fig. 4 dargstellten Rollenhebel 46, 46a zur Steuerung der Schubstangen 41, 41a sowie die Rollenhebel 53, 53a zur Steuerung der Schubstangen 48, 48a werden über zusätzliche Zugstangen 55 bis 55c durch Kolben-Zylindereinheiten 56 bis 56c an die zugehörigen Schwenkkurven 47, 47a bzw. 54, 54a angedrückt (s. Fig. 1).The roller levers 46, 46a shown in FIG. 4 for controlling the push rods 41, 41a and the roller levers 53, 53a for controlling the push rods 48, 48a are connected to the associated pivoting curves 47 via additional pull rods 55 to 55c by piston-cylinder units 56 to 56c , 47a or 54, 54a (see FIG. 1).

Das Kurvengetriebe mit den Schwenkkurven 47, 54 bzw. 47a, 54a sowie den Vorschubkurven 32, 32a, 36, 36a und den Antriebskurven 18, 18a ist in einem jeweiligen Kurvengehäuse 57 bzw. 57a gelagert und über ein angeflanschtes Getriebe 58, 58a von der Presse angetrieben.The cam mechanism with the swivel curves 47, 54 or 47a, 54a and the feed curves 32, 32a, 36, 36a and the drive curves 18, 18a is mounted in a respective cam housing 57 or 57a and from the press via a flanged gear 58, 58a driven.

Die Werkstücke bzw. Platinen werden von einem nicht näher dargestellten Platinenlader in das Werkzeug 3 eingelegt. Nach dem Umformprozeß werden die auf den Unterwerkzeugen 3, 4 liegenden Blechteile 62, 63 von der zugehörigen Austrage-Quertraverse 25, 26 entnommen und entsprechend der Transportkurve 64 auf die Ablegestufen 65, 66 innerhalb der Pressenständer bzw. Leerstufen 10, 11 transportiert (s. Fig. 1). Dabei werden während der Hebe- und im ersten Teil der Transportbewegung die Austrage-Quertraversen 25, 26 durch die Schwenkkurven 47, 47a über die Hebel und Antriebsgestänge von der Schräglage in der Bearbeitungsstufe ein eine Waagerechtlage geschwenkt.The workpieces or blanks are inserted into the tool 3 by a blank loader, not shown. After the forming process, the sheet metal parts 62, 63 lying on the lower tools 3, 4 are removed from the associated discharge crossbeam 25, 26 and transported according to the transport curve 64 to the depositing stages 65, 66 within the press stands or empty stages 10, 11 (see. Fig. 1). During the lifting and in the first part of the transport movement, the discharge crossbeams 25, 26 are pivoted from the inclined position in the processing stage to a horizontal position by the pivoting curves 47, 47a via the levers and drive linkages.

Das Zurückfahren der Quertraversen 25, 26 aus der Ablegestufe 65, 66 im Pressenständerbereich 10, 11 in eine zwischen Bearbeitungsstufe und Leerstufe liegende Warteposition 67 erfolgt nach der Fahrkurve 68. Die Austrage-Quertraversen 25, 26 bleiben dabei in der waagerechten Stellung (s. Fig. 1).The retraction of the crossbeams 25, 26 from the laying stage 65, 66 in the press stand area 10, 11 into one Waiting position 67 lying between the processing stage and the empty stage follows the driving curve 68. The discharge cross members 25, 26 remain in the horizontal position (see FIG. 1).

Das Einfahren der Quertraversen 25, 26 in die Werkzeuge 3, 4 erfolgt nach der dargestellten Fahrkurve 69. Dabei schwenken die Austrage-Quertraversen 25, 26 während der Senkbewegung und im letzten Teil der Horizontalbewegung wieder in eine Schräglage, zum Entnehmen der Blechteile in den Bearbeitungsstufen (Fig. 1).The crossbars 25, 26 are retracted into the tools 3, 4 according to the illustrated driving curve 69. The discharge crossbars 25, 26 swivel back into an inclined position during the lowering movement and in the last part of the horizontal movement, in order to remove the sheet metal parts in the processing stages (Fig. 1).

Sinngemäß erfolgt der gleiche Prozeß mit den Eintrage-Quertraversen 27, 28. Diese entnehmen die Blechteile 70, 71 aus der Ablegestufe 65 bzw. 66 in einer Waagerechtlage und transportieren diese nach der Fahrkurve 72 in die darauffolgende Werkzeugstufe 4 bzw. in die nicht mehr dargestellte nachfolgende Werkzeugstufe (s. Fig. 1). Dabei schwenken die Eintrage-Quertraversen 27, 28 in der Senkbewegung und im letzten Teil der Transportbewegung wiederum in eine Schräglage, um das Blechteil in einer Schräglage auf das Unterwerkzeug 3, 4 zu plazieren. Das Drehen in die Schräglage erfolgt wiederum durch zugehörige Schwenkhebel 39, 39a bzw. 40, 40a, die über die Schubstangen und Hebel mit den Schwenkkurven 54, 54a in Wirkverbindung stehen.Analogously, the same process takes place with the transverse cross members 27, 28. These remove the sheet metal parts 70, 71 from the laying stage 65 or 66 in a horizontal position and transport them after the driving curve 72 into the subsequent tool stage 4 or into the one that is no longer shown subsequent tool stage (see Fig. 1). The entry cross members 27, 28 pivot in the lowering movement and in the last part of the transport movement again into an inclined position in order to place the sheet metal part in an inclined position on the lower tool 3, 4. The turning into the inclined position is in turn carried out by the associated pivot levers 39, 39a or 40, 40a, which are operatively connected to the pivot curves 54, 54a via the push rods and levers.

Das Zurückfahren der Eintrage-Quertraversen 27, 28 in die Warteposition 73 erfolgt längs der Fahrkurve 74. Dabei schwenken wiederum die Eintrage-Quertraversen 27, 28 während der Hubbewegung und im ersten Teil der Transportbewegung wieder in die Waagerechtstellung.The return crossbars 27, 28 are moved back to the waiting position 73 along the travel curve 74. The crossbars 27, 28, in turn, pivot again into the horizontal position during the lifting movement and in the first part of the transport movement.

Das Einfahren in die Ablegestufen 65, 66 erfolgt nach der dargestellten Fahrkurve 75. Dabei bleiben die Eintrage-Quertraversen 27, 28 in der waagerechten Lage.The entry into the depositing stages 65, 66 takes place according to the illustrated driving curve 75. The transverse cross members 27, 28 remain in the horizontal position.

Werden Blechteile gefertigt, die eine waagerechte Lage in den Werkzeugen einnehmen sollen, so können die Drehbewegungen der Quertraversen 25 bis 28 durch umgekehrtes Beaufschlagen der Kolben-Zylindereinheiten 56 bis 56c abgeschaltet werden. Die Quertraversen bleiben dann in einer waagerechten Lage.If sheet metal parts are manufactured which are to have a horizontal position in the tools, the rotary movements of the crossbeams 25 to 28 can be switched off by reversely acting on the piston-cylinder units 56 to 56c. The crossbeams then remain in a horizontal position.

Es können auch nur die Eintrage-Quertraversen 27, 28 oder die Austrage-Quertraversen 25, 26 verdreht werden, was durch ein entsprechendes Beaufschlagen der zugehörigen Kolben-Zylindereinheiten erfolgt.It is also possible to twist only the transverse cross members 27, 28 or the transverse cross members 25, 26, which is done by correspondingly loading the associated piston-cylinder units.

Die zuvor beschriebenen Bewegungen der Platinen zwischen den einzelnen Stationen sind in den Figuren 2 und 3 näher dargestellt. Dabei zeigt die Fig. 2 einen Bewegungsablauf, bei welchem sich das Blechteil 62 in einer horizontalen Lage zwischen dem Unterwerkzeug 3 und der nachfolgenden Ablegestufe 65 befindet (Fahrkurve 64). Gleichzeitig wird das aus der Ablegestufe 65 heraustransportierte Blechteil 70 in eine waagerechte Transportposition in die nachfolgende Bearbeitungsstufe mit Unterwerkzeug 4 transportiert (Fahrkurve 72). Das Blechteil 63 wird auf einer entsprechenden Fahrkurve 64 in die Ablegestation 66 transportiert.The previously described movements of the boards between the individual stations are shown in more detail in FIGS. 2 and 3. 2 shows a sequence of movements in which the sheet metal part 62 is in a horizontal position between the lower tool 3 and the subsequent depositing stage 65 (driving curve 64). At the same time, the sheet metal part 70 transported out of the depositing stage 65 is transported into a horizontal transport position in the subsequent processing stage with the lower tool 4 (travel curve 72). The sheet metal part 63 is transported to the placement station 66 on a corresponding driving curve 64.

Fig. 3 zeigt die nachfolgende Stellung des Platinentransports. Hier ist das Blechteil 62 in die Ablegestufe 65 in waagerechter Lage abgelegt. Gleichermaßen ist das Blechteil 70 aus der Ablegestufe 65 in die nachfolgende Bearbeitungsstufe mit Werkzeug 4 in schräger Position abgelegt. Die von der Quertraverse auf der Fahrkurve 72 durchgeführte Drehbewegung ist mit dem Winkel α angegeben, wobei der Winkelstrahl 87 parallel zum Winkelstrahl 88 ist. Das in Fig. 1 in der Bearbeitungsstufe 4 angeordnete Blechteil 63 ist in Fig. 3 auf die Ablegestufe 66 in waagerechter Position abgelegt.Fig. 3 shows the subsequent position of the board transport. Here, the sheet metal part 62 is placed in the laying stage 65 in a horizontal position. Likewise, the sheet metal part 70 is from the storage stage 65 in the Subsequent processing stage with tool 4 stored in an inclined position. The rotary movement carried out by the crossmember on the driving curve 72 is indicated by the angle α, the angle beam 87 being parallel to the angle beam 88. The sheet metal part 63 arranged in the processing stage 4 in FIG. 1 is deposited in FIG. 3 on the laying stage 66 in a horizontal position.

Die Verschiebung der Schubstangen 29, 33 mit nachgeschalteten Pleuelstangen 30, 34 durch das Kurvengetriebe 47, 54 über die Schubstangen 45, 52 mit Winkelhebel 44, 51 ist aus den Darstellungen der Figuren 1 bis 3 deutlich ersichtlich.The displacement of the connecting rods 29, 33 with connecting rods 30, 34 connected downstream by the cam mechanism 47, 54 via the connecting rods 45, 52 with angle levers 44, 51 can be clearly seen from the illustrations in FIGS. 1 to 3.

Die Erfindung ist nicht auf das dargestellte und beschriebene Ausführungsbeispiel beschränkt. Sie umfaßt auch vielmehr alle fachmännischen und vorteilhaften Weiterbildungen im Rahmen der Schutzrechtsansprüche.The invention is not restricted to the exemplary embodiment shown and described. Rather, it also encompasses all professional and advantageous further training within the scope of the property right claims.
