Description

"Transfervorrichtung für eine Presse""Transfer device for a press"
Beschreibungdescription
Die Erfindung betrifft eine Transfervorrichtung für eine Presse nach dem Oberbegriff des Anspruch 1.The invention relates to a transfer device for a press according to the preamble of claim 1.
Stand der TechnikState of the art
Eine Transportvorrichtung zum Transportieren von Werkstücken in einer Transferpresse besteht in der Regel aus zwei in Transportrichtung der Werkstücke verlaufenden Greiferschienen, die neben der Längs- und Hubbewegung eine zusätzliche Querbewegung durchführen, wobei Greiferelemente an den Greiferschienen vorgesehen sind. Zum Antrieb dieser Greiferschienen verwendet man in jüngster Zeit unterschiedliche elektrische Antriebe, welche die früher üblichen mechanischen, an den Pressenantrieb gekoppelten Antriebe nahezu vollständig abgelöst haben.A transport device for transporting workpieces in a transfer press usually consists of two in the transport direction of the workpieces extending gripper rails, which perform an additional transverse movement in addition to the longitudinal and lifting movement, said gripper elements are provided on the gripper rails. To drive these gripper rails used in recent times different electrical drives, which have almost completely replaced the previously customary mechanical, coupled to the press drive drives.
Nach der DE 195 06 079 Al ist eine Vorrichtung zum Transfer von Werkstücken durch eine Folge von Bearbeitungsstationen einer Presse, eines Simulators oder dergleichen bekannt, die zwei parallel im Abstand zueinander, sich in Transportrichtung erstreckende Transportschienen aufweist. An denAccording to DE 195 06 079 Al a device for the transfer of workpieces by a series of processing stations of a press, a simulator or the like is known, which has two parallel spaced apart, extending in the transport direction transport rails. To the
Transportschienen sind Aufnahmeeinrichtungen für die zu transportierenden Werkstücke angeordnet. Die Transportschienen sind insgesamt mittels jeweils paarweise angeordneten Linearmotoren in vertikaler Richtung und horizontal aufeinander zu bewegbar. Die Antriebseinrichtungen für die Bewegungen in den drei Bewegungsachsen sind als paarweise angeordnete Linearmotoren ausgeführt, wobei die sich bezüglich der Mittelachse der Presse gegenüberliegenden Linearmotoren synchron ansteuerbar sind. Nachteilig bei dieser Lösung sind die großen Massen an bewegten Teilen. Insbesondere die Antriebe der einzelnen Bewegungsachsen sind übereinander angeordnet und müssen dadurch während der Transportbewegung mitbewegt werden. Dies wirkt sich negativ auf die Dynamik des Gesamtsystems aus. Weiterhin nachteilig ist, dass die eingesetzten Linearmotoren nur bedingt für den Einsatz in Umformmaschinen geeignet sind, weil durch eine magnetische Anziehungskraft Partikel angezogen werden und so zusammen mit anderen Schmutzteilchen die Laufflächen der Linearantriebe verunreinigen. Dies hat einen erhöhten Wartungsaufwand zur Folge. Durch den Einsatz von Linearführungen müssen außerdem Nachteile wie zum Beispiel Verschließ der Führungen oder Verschmutzung der Anlage durch die Schmierung der Führungen in Kauf genommen werden. Auch die Schmierleitungen müssen konstruktiv vorgesehen werden.Transport rails receiving means for the workpieces to be transported are arranged. The transport rails are in total by means of paired linear motors in the vertical direction and horizontally toward each other to move. The drive means for the movements in the three axes of movement are designed as paired linear motors, wherein the opposite with respect to the center axis of the press linear motors are controlled synchronously. The disadvantage of this solution are the large masses of moving parts. In particular, the drives of the individual axes of movement are arranged one above the other and must therefore be moved during the transport movement. This has a negative effect on the dynamics of the overall system. Another disadvantage is that the linear motors used are only partially suitable for use in forming machines because particles are attracted by a magnetic attraction and thus contaminate the running surfaces of the linear drives together with other dirt particles. This results in increased maintenance. Through the use of linear guides also disadvantages such as closure of the guides or contamination of the system by the lubrication of the guides must be taken into account. The lubrication lines must be provided constructively.
Die DE 100 12 022 Al tritt diesen Nachteilen bereits entgegen. Es wird ein Transferantrieb offenbart, der weitgehenst auf wartungsintensive Führungen für die einzelnen Bewegungselemente verzichtet. Vorgeschlagen wird ein Antrieb, der aus beweglichen Gelenkstangen in hängender Anordnung besteht. Durch die Verwendung eines dreidimensionalen Antriebs wird eine Art „Mehr-Punkt-Aufhängung" geschaffen, das heißt, die Greiferschienen sind in allen drei Bewegungsachsen definiert an Gelenken aufgehängt, so dass auf übliche Führungen verzichtet werden kann. Dabei ist es vorteilhaft, dass sämtliche Gelenkstangen und Schubstangen oberhalb der Transportebene der Werkstücke angeordnet sind, so dass der Werkzeugraum sehr gut zugänglich ist und keine störenden Bodengeräte vorhanden sind. Insbesondere beim Einsatz von Förderbändern oder Ablagestationen wirkt sich dies vorteilhaft aus .DE 100 12 022 Al already counteracts these disadvantages. It is disclosed a transfer drive, the weitgehenst waived maintenance-intensive guides for the individual movement elements. Proposed is a drive, which consists of movable link rods in a hanging arrangement. The use of a three-dimensional drive creates a kind of "multi-point suspension", that is to say that the gripper rails are suspended on joints in all three axes of movement in a defined manner, so that conventional guides can be dispensed with. that all joint rods and push rods are arranged above the transport plane of the workpieces, so that the tool room is very accessible and no disturbing ground devices are present. In particular, when using conveyor belts or storage stations, this has an advantageous effect.
Nachteilig an dieser Anordnung ist, dass die konstruktive Anordnung der Antriebe und der Gelenkstangen sehr viel Platz beansprucht. Insbesondere die Bewegungsübertragung für die Öffnen- und Schließbewegung der Greiferschienen wird über einen sehr ausladenden Mechanismus aus Drehgelenken und Gelenkstangen übertragen. Dies hat zur Folge, dass der oben beschriebene Transferantrieb komplett außerhalb der Ständer in Durchlaufrichtung angebracht werden muss. Dadurch müssen die Greiferschienen so lang sein, dass sie beidseitig aus den Ständerbereichen herausragen. Dies bedeutet wiederum eine große Masse, welche bei der Transportbewegung mitbewegt werden muss und somit eine Verschlechterung der Dynamik im Vergleich zum Einsatz von kürzeren Greiferschienen. Durch die Aufhängung der Greiferschienen außerhalb der Pressenständer ist der Auflagenabstand relativ groß, was eine große Durchbiegung der Greiferschienen zur Folge hat. Um die Durchbiegung zu verringern müssen die Greiferschienen mit größeren Wandstärken ausgestaltet werden. Dies wirkt sich auf die Dynamik wiederum negativ aus .A disadvantage of this arrangement is that the structural arrangement of the drives and the joint rods takes up a lot of space. In particular, the motion transmission for the opening and closing movement of the gripper rails is transmitted via a very bulky mechanism of hinges and link rods. This has the consequence that the transfer drive described above has to be mounted completely outside the stand in the direction of passage. As a result, the gripper rails must be so long that they protrude from both sides of the stator areas. This in turn means a large mass, which must be moved during the transport movement and thus a deterioration of the dynamics compared to the use of shorter gripper rails. By the suspension of the gripper rails outside the press stand, the support distance is relatively large, which has a large deflection of the gripper rails result. To reduce the deflection, the gripper rails must be designed with larger wall thicknesses. This in turn has a negative impact on dynamics.
Ein weiterer Nachteil, der aus dem großen Platzbedarf des beschriebenen Transferantriebes resultiert ist, dass für einige Anwendungen, bei denen kundenseitig nur ein begrenzter Platz zur Verfügung steht, dieser Transfer nicht einsetzbar ist. Aufgabe und Vorteil der ErfindungAnother disadvantage resulting from the large space requirement of the transfer drive described is that for some applications in which the customer only a limited space is available, this transfer can not be used. Task and advantage of the invention
Der Erfindung liegt die Aufgabe zugrunde ausgehend vom oben beschriebenen Stand der Technik einen Transferantrieb zu entwickeln, bei dem die Greiferschienen über Gelenkstangen gehalten und mittels Servomotoren angetrieben werden und bei dem die Antriebsmittel und die Bewegungsübertragungsmittel größtenteils im Ständerbereich angeordnet sind. Mit einem Minimum an bewegten Teilen soll der erfindungsgemäßeThe invention is based on the object starting from the above-described prior art to develop a transfer drive, in which the gripper rails are held by link rods and driven by servo motors and in which the drive means and the motion transmission means are largely arranged in the stator area. With a minimum of moving parts of the invention
Transferantrieb außerdem kompakt und somit kostengünstig gestaltet werden. Diese Aufgabe wird ausgehend von einer Transfervorrichtung nach dem Oberbegriff des Anspruch 1 durch die kennzeichnenden Merkmale des Anspruch 1 gelöst. In den Unteransprüchen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Transfervorrichtung verwirklicht .Transfer drive also be made compact and therefore inexpensive. This object is achieved on the basis of a transfer device according to the preamble of claim 1 by the characterizing features of claim 1. In the dependent claims advantageous refinements and improvements of the main claim transfer device are realized.
Der Erfindung liegt der Kerngedanke zugrunde die Bewegungsübertragungsmittel, welche zwischen den Antrieben und den Greiferschienen wirken so anzuordnen, dass diese größtenteils zwischen den Ständern Platz finden. Dabei sollen keine Linearführungen zum Einsatz kommen, sondern ausschließlich Gelenke welche sich aufgrund geringer Reibverluste durch einen höheren Wirkungsgrad auszeichnen. Außerdem lassen sich Gelenke besser schmieren und abdichten.The invention is based on the core idea of the motion transmission means, which act between the drives and the gripper rails to be arranged so that they mostly find space between the stands. In this case, no linear guides are used, but only joints which are characterized by low friction losses by a higher efficiency. In addition, joints can be lubricated and sealed better.
Trotz der kompakten Bauweise der erfindungsgemäßen Transfervorrichtung sind neben den Transportfunktionen auch alle weiteren Funktionen wie sie aus dem Stand der Technik für eine Greifertransfervorrichtung bekannt sind, wie zum Beispiel Greiferschienenweitenversteilung oder Werkzeugwechselfunktionen, durchführbar . Die erfindungsgemäße Transfervorrichtung ist auf zwei Traversen gelagert, welche an den jeweiligen Ständerpaaren befestigt sind. Auf diesen Traversen sind die Antriebe quer zur Durchlaufrichtung verstellbar gelagert, um eineDespite the compact design of the transfer device according to the invention, in addition to the transport functions, all other functions known from the prior art for a gripper transfer device, such as gripper rail width adjustment or tool change functions, are feasible. The transfer device according to the invention is mounted on two trusses, which are attached to the respective pair of stands. On these trusses, the drives are mounted transversely to the passage direction adjustable to a
Weitenverstellung der Greiferschiene zu ermöglichen. Die Vorschubbewegung, die Hebehubbewegung und die Öffnen- /Schließbewegung werden dadurch erzeugt, dass an den Greiferschienenenden Gelenkstangen bzw. Gelenkstangenpaare sphärisch gelagert sind. Die entgegengesetzten Enden der Gelenkstangen sind wiederum sphärisch an Hebeln gelagert, welche mit den jeweiligen Antrieben drehbar verbunden sind.To allow width adjustment of the gripper rail. The advancing movement, the lifting stroke movement and the opening / closing movement are generated by the fact that articulated rods or pairs of connecting rods are mounted spherically on the gripper rails. The opposite ends of the link rods are in turn mounted spherically on levers, which are rotatably connected to the respective drives.
Ein wesentliches Merkmal der erfindungsgemäßen Transfervorrichtung ist die Anordnung des Öffnen- /Schließbewegungsstranges . Durch die oben genannte Aufgabenstellung, die Bewegungsübertragungsmittel im Ständerbereich so zu platzieren, ist es nicht mehr möglich wie im Stand der Technik bekannt, die Greiferschiene von außen anzulenken und mit geeigneten Hebelmechanismen eine Bewegung einzuleiten.An essential feature of the transfer device according to the invention is the arrangement of the opening / closing movement strand. As a result of the abovementioned task of placing the motion transmission means in the stand area, it is no longer possible, as is known in the prior art, to move the gripper rail from the outside and to initiate a movement with suitable lever mechanisms.
Bei der erfindungsgemäßen Transfervorrichtung werden daher die Antriebsstränge für die Öffnen-/Schließbewegungen mittig zwischen den Greiferschienen, symmetrisch zurIn the transfer device according to the invention, therefore, the drive trains for the opening / closing movements are centered between the gripper rails, symmetrical to

Auch die Antriebseinheit für die Öffnen-/Schließbewegung ist wie auch die Antriebseinheiten für den Vorschub und' den Hebehub auf einer Traverse, quer zur Durchlaufrichtung verstellbar bzw. verfahrbar angebracht. Durch die platzsparende Anordnung im Ständerbereich ist die erfindungsgemäße Transfervorrichtung E2007/001716Machine centerline arranged. For each gripper rail end, a drive train is preferably provided. Also, the drive unit for the opening / closing movement as well as the drive units for the feed and ' the lifting stroke on a crossbar, transversely to the direction of passage adjustable or movable. Due to the space-saving arrangement in the stator area is the transfer device according to the invention E2007 / 001716

Figur 1 zeigt einen Ausschnitt aus einer Presse 1 in einer Seitenansicht in vereinfachter Darstellung. Zu sehen sind die Ständer 2, 3 an denen ein Stößel 4 vertikal verfahrbar geführt wird. Der Antrieb des Stößels 4 ist in dieser Figur nicht dargestellt. Ebenfalls nicht dargestellt ist das Werkzeug, bestehend aus Ober- und Unterwerkzeug. Während das Oberwerkzeug mit dem Stößel 4 verbunden ist, ist das Unterwerkzeug auf einem Schiebetisch 5 befestigt, welcher seinerseits während der Produktion mit einem Tisch 6 verspannt ist.Figure 1 shows a section of a press 1 in a side view in a simplified representation. You can see the stand 2, 3 at which a plunger 4 is guided vertically movable. The drive of the plunger 4 is not shown in this figure. Also not shown is the tool consisting of upper and lower tool. While the upper tool is connected to the plunger 4, the lower tool is mounted on a sliding table 5, which in turn is clamped during production with a table 6.
Die erfindungsgemäße Transfervorrichtung 7 ist auf der einen Seite über eine Traverse 8 an dem Ständerpaar 2 und auf der anderen Seite über eine Traverse 9 an dem Ständerpaar 3 befestigt .The transfer device 7 according to the invention is fastened on the one side via a traverse 8 on the pair of stands 2 and on the other side via a traverse 9 on the pair of stands 3.
Figur 2 veranschaulicht die Anbausituation in einer Draufsicht. Die Greiferschienen 10, 11 sind um einen Werkzeugwechsel zu ermöglichen geteilt. DieFigure 2 illustrates the cultivation situation in a plan view. The gripper rails 10, 11 are divided to enable a tool change. The
Greiferschienenendstücke 10a, 10b und IIa, IIb verbleiben bei einem Werkzeugwechsel in der Presse 1, während die Greiferschienenteile 10 und 11 gemeinsam mit dem Werkzeug und dem Schiebetisch 5 aus der Presse 1 herausgefahren werden. Die Greiferschienenendstücke 10a, b, IIa, b sind jeweils an drei Gelenkstangen bzw. Gelenkstangenpaaren aufgehängt und über diese mit den jeweiligen Antrieben verbunden. Die Vorschubbewegung der Greiferschienen 10 und 11 werden über die Antriebe 12a, b erzeugt, welche über Schwenkhebel 13 und eine Gelenkstange 14 auf das Greiferschienenendstück IIb einwirken. Sowohl das Greiferschienenendstück IIb mit der Gelenkstange 14, als auch die Gelenkstange 14 mit dem Schwenkhebel 13 sind über eine sphärische Lagerung 15 miteinander verbunden. Die Antriebsstränge für die Vorschubbewegung sind an den Ständerpaaren 3a, 3b spiegelbildlich zur Maschinenmitte 16 angeordnet. Die Antriebsstränge für die Hubbewegung und für die Öffnen-/Schließbewegung greifen hingegen an allen vier Greiferschienenendstücken 10a, b und IIa, b an. Ein Antriebsstrang für die Hubbewegung beispielsweise der Greiferschiene 10 besteht aus einem Antrieb 17, einem Schwenkhebel 18 und einem Gelenkstangenpaar 19. Für den Hubantrieb wird keine einzelne Gelenkstange sondern ein Gelenkstangenpaar 19 vorgesehen, damit ein Kippen der Greiferschiene 10 um ihre Längsachse verhindert wird. Das Gelenkstangenpaar 19 ist ähnlich einen Parallelogramm angeordnet, so dass die Ausrichtung der Greiferschiene 10 immer gleich bleibt. In Figur 3 ist diese Anordnung gut zu erkennen.Gripper rail end pieces 10a, 10b and IIa, IIb remain in a tool change in the press 1, while the gripper rail parts 10 and 11 are moved out of the press 1 together with the tool and the sliding table 5. The gripper rail end pieces 10a, b, IIa, b are each suspended from three articulated rods or pairs of connecting rods and connected via these with the respective drives. The feed movement of the gripper rails 10 and 11 are generated via the drives 12a, b, which act on the gripper rail end piece IIb via pivot lever 13 and a link rod 14. Both the gripper rail end piece IIb with the articulated rod 14, and the articulated rod 14 with the pivot lever 13 are connected to each other via a spherical bearing 15. The drive trains for the feed movement are arranged on the stator pairs 3a, 3b in mirror image to the machine center 16. In contrast, the drive trains for the lifting movement and for the opening / closing movement engage on all four gripper rail end pieces 10a, b and IIa, b. A drive train for the lifting movement, for example, the gripper rail 10 consists of a drive 17, a pivot lever 18 and a pair of hinge rods 19. For the linear actuator not a single link rod but a pair of hinge rods 19 is provided so that tilting of the gripper rail 10 is prevented about its longitudinal axis. The pair of hinges 19 is similarly arranged a parallelogram, so that the orientation of the gripper rail 10 always remains the same. In Figure 3, this arrangement is clearly visible.
Der Antriebsstrang für die Öffnen-/Schließbewegung besteht aus einem Antrieb 20, einem Schwenkhebel 21 und einer Gelenkstange 22. Wie bei allen Antriebssträngen sind auch in diesem Fall die einzelnen Bauteile sphärisch gelagert miteinander verbunden. Kennzeichnend für den Öffnen-/Schließantrieb 20 ist seine Position zwischen den Hubantrieben 17, symmetrisch zur Maschinenmitte 16. Die Vorteile dieser Anordnung wurden bereits beschrieben, problematisch bei dieser Anordnung ist allerdings die Anlenkung der Greiferschienen 10, 11 über die Gelenkstangen 22 aufgrund der Platzverhältnisse durch die Anlenkung des Hubantriebes 17 über die Gelenkstangenpaare 19. Die erfindungsgemäße Transfervorrichtung löst diese Problematik dadurch, dass die Gelenkstange 22 an ihrem der Greiferschiene zugewandten Ende als eine Art Gabel ausgebildet ist, welche zumindest eine Gelenkstange desThe drive train for the opening / closing movement consists of a drive 20, a pivot lever 21 and a link rod 22. As in all drive trains, the individual components are mounted spherically mounted together in this case. Characteristic of the opening / closing drive 20 is its position between the lifting drives 17, symmetrical to the machine center 16. The advantages of this arrangement have already been described, but problematic in this arrangement is the articulation of the gripper rails 10, 11 on the hinge rods 22 due to the space the articulation of the lifting drive 17 via the hinge rod pairs 19. The transfer device according to the invention solves this problem by the fact that the pivot rod 22 at her the Gripper rail facing the end is designed as a kind of fork, which at least one joint rod of the
Gelenkstangenpaares 19 umschließt und so an einem sphärischen Gelenk 15 an der Greiferschiene 10, 11 angreifen kann. Obwohl in dieser Beschreibung die Antriebsstränge für die dreiCoupling rod pair 19 encloses and so on a spherical joint 15 on the gripper rail 10, 11 can attack. Although in this description the drive trains for the three
Bewegungen Vorschub, Hebehub und Öffnen-/Schließen beschrieben werden, ist aus der konstruktiven Gestaltung ersichtlich, dass diese Bewegungen jede für sich nur aus Bewegungsüberlagerungen aller Antriebe realisierbar sind. Diese Bewegungsüberlagerungen werden durch eine geeignete Steuerung errechnet und an die Servoantriebe übertragen.Movements feed, lifting and opening / closing are described, it can be seen from the structural design that these movements are each feasible only from Bewegungsüberlagerungen all drives. These motion overlays are calculated by a suitable controller and transmitted to the servo drives.
Alle Antriebe sind über Schlitten 23 verfahrbar entlang einer Traverse 9 gelagert. Mittels eines Antriebes 24a können diese beispielsweise über ein Spindel 24/Spindelmutter 25 - System verfahren werden. Auch andere aus dem Stand der Technik bekannten Bewegungsübertragungsmittel sind denkbar.All drives are mounted on carriages 23 movable along a traverse 9. By means of a drive 24a, these can be moved, for example, via a spindle 24 / spindle nut 25 system. Other known from the prior art motion transmission means are conceivable.
Ausführungsbeispiel für den Einsatz in einer MehrstößelpresseEmbodiment for use in a multi-ram press
In Figur 4 ist der Einsatz der erfindungsgemäßen Transfervorrichtung 27 in einer Mehrstößeltransferpresse dargestellt. Wie man sieht ist in jedem Ständerbereich eine Transfereinheit 27 angebracht, bestehend aus Hubantrieb 17 und Öffnen-/Schließantrieb 20 sowie den zugehörigen Bewegungsübertragungsmittel. Der Vorschub für die durchgehenden Greiferschienen erfolgt über einen Antrieb 29. Da die Greiferschienen 28 in Mehrstößelpressen in der Regel sehr lang sind und somit eine große Masse besitzen ist es möglich, wie in Figur 4 dargestellt, zwei oder mehrere Antriebe einzusetzen, welche auf denselben Vorschubhebel wirken. Weiterhin dargestellt ist eine Variante der erfindungsgemäßen Transfervorrichtung 27, bei der die Drehachsen der Schwenkhebel für die Hubbewegung und für die Öffnen-/Schließbewegung um 90° gedreht werden. Dies hat den Vorteil, dass der Platzbedarf der Transfervorrichtung 27 zwischen den Ständern noch geringer wird.FIG. 4 shows the use of the transfer device 27 according to the invention in a multi-ram transfer press. As you can see, a transfer unit 27 is mounted in each stand area, consisting of lifting drive 17 and opening / closing drive 20 and the associated motion transmission means. The feed for the continuous gripper rails via a drive 29. Since the gripper rails 28 in multi-ram presses are usually very long and thus have a large mass, it is possible, as shown in Figure 4, two or more To use drives, which act on the same feed lever. Also shown is a variant of the transfer device 27 according to the invention, in which the axes of rotation of the pivot lever for the lifting movement and for the opening / closing movement are rotated by 90 °. This has the advantage that the space requirement of the transfer device 27 between the uprights is even lower.
In Figur 5 ist diese Variante in einer Ansicht in Durchlaufrichtung dargestellt. Die Gelenkstangenpaare 19 für den Hubantrieb 17 werden von einem Schwenkhebel 30 bewegt, welcher um eine Achse in Durchlaufrichtung schwenkt. In gleicher Richtung schwenkt der Hebel 31 um die Gelenkstangen 22 für die Öffnen-/Schließbewegung anzutreiben.In Figure 5, this variant is shown in a view in the direction of passage. The pairs of connecting rods 19 for the lifting drive 17 are moved by a pivot lever 30, which pivots about an axis in the direction of passage. In the same direction pivots the lever 31 to drive the hinge rods 22 for the opening / closing movement.
Die Erfindung sieht weiterhin vor, dass für die Öffnen- /Schließbewegung statt einem Schwenkhebel 31 oder 21 ein Linearantrieb Verwendung findet. Das Gelenk 32 könnte dabei beispielsweise auf einem Schlitten gelagert werden, welcher in vertikaler Richtung antreibbar ist. Die Erfindung sieht außerdem vor, dass die Öffnen-/Schließbewegung durch eine dynamische Längenänderung der Gelenkstange erfolgt. Diese Längenveränderungen können beispielsweise durch einen Spindelmechanismus erzeugt werden, aber auch andere im Stand der Technik bekannte Antriebsmechanismen, wie zum Beispiel Hydraulikzylinder sind denkbar.The invention further provides that, instead of a pivoting lever 31 or 21, a linear drive is used for the opening / closing movement. The joint 32 could be stored, for example, on a carriage which is drivable in the vertical direction. The invention also provides that the opening / closing movement is effected by a dynamic change in length of the joint rod. These changes in length can be generated for example by a spindle mechanism, but other known in the art drive mechanisms, such as hydraulic cylinders are conceivable.
Die Erfindung sieht weiterhin vor, die oben beschriebene dynamische Längenänderung der Gelenkstange in Kombination mit einem Antrieb über Schwenkhebel oder einem Linearantrieb einzusetzen um so über eine Bewegungsüberlagerung die Dynamik nochmals zu verbessern.The invention further provides, the above-described dynamic change in length of the articulated rod in combination with a drive via pivot lever or a linear drive to use a movement overlay to improve the dynamics again.
Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt. Sie umfasst auch alle fachmännischen Weiterbildungen im Rahmen des erfindungsgemäßen Gedankens. The invention is not limited to the illustrated and described embodiments. It also includes all expert developments within the scope of the inventive concept.
