Die Abstandselemente 30 sind im Aufstandsbereich als Positionierfortsätze 31 ausgebildet, z.B. konische Endbereiche von denen zumindest zwei benachbarte Positionierfortsätze 31 in Zentrieraufnahmen 32, die bevorzugt in der Fußplatte 7 der Manipulationseinrichtung 5 vorgesehen sind, in Eingriff sind und damit der Stellplatz 27 bzw. der Transportträger 2 bzw. ein Stapelschacht 3 eine definierte Referenzposition - wie noch später ausführlich beschrieben - in Bezug auf die Manipulationseinrichtung 5 einnimmt. Die Ausbildung der Abstandselemente 30 mit den Positionierfortsätzen 31 und den Zentrieraufnahmen 32 gewährleistet die Einnahme der Referenzposition bei einem Austausch von Transportträgern 2 ohne aufwendige Positioniermaßnahmen.The spacer elements 30 are formed in the contact area as positioning projections 31, e.g. Conical end portions of which at least two adjacent positioning extensions 31 in Zentrieraufnahmen 32, which are preferably provided in the base plate 7 of the manipulation device 5, are engaged and thus the pitch 27 and the transport carrier 2 and a stacking shaft 3 a defined reference position - as later described in detail - with respect to the manipulation device 5 occupies. The formation of the spacers 30 with the positioning projections 31 and the centering 32 ensures the capture of the reference position in an exchange of transport carriers 2 without complex positioning measures.

Durch die Ausbildung der Positionierfortsätze 31 an den in den Eckbereichen des Transportträgers 2 angeordneten Abstandselementen 30 und zweier Zentrieraufnahmen 32 in der Grundplatte 7 wird beispielsweise bei Transportträger 2 mit einem Rechteckformat ein Umschlag des Transportträgers 2 um 180°, um eine zur Aufstandsfläche 6 im rechten Winkel ausgerichtete Zentrumsachse durch einen Flächenmittelpunkt 33 des Transportträgers 2, bzw. um 90° bei einem Quadratformat des Transportträgers 2 erreicht. Dies ermöglicht auch eine Anordnung mehrerer Stapelschächte 3, auf der Tragplatte 28, z.B., zwei Stapelschächte 3 bei einem Rechteckformat des Transportträgers 2 bzw. vier bei einem Quadratformat ohne Veränderungen im Steuerungsprogramm zur Ansteuerung der Manipulationseinrichtung 5 vornehmen zu müssen.By forming the positioning projections 31 at the arranged in the corner regions of the transport carrier 2 spacers 30 and two Zentrieraufnahmen 32 in the base plate 7, for example, in transport carrier 2 with a rectangular format, an envelope of the transport carrier 2 by 180 °, to a footprint 6 at right angles aligned center axis through a center of area 33 of the transport carrier 2, or 90 ° in a square format of the transport carrier 2 achieved. This also enables an arrangement of a plurality of stacking shafts 3, on the support plate 28, for example, to have to make two stacking shafts 3 in a rectangular format of the transport carrier 2 or four in a square format without changes in the control program for controlling the manipulation device 5.

Wie dem gezeigten Ausführungsbeispiel zu entnehmen, ist es selbstverständlich auch möglich, bei einem entsprechend langen Verstellweg des turmförmigen Gehäuses 11 in der Linearführungseinrichtung 8 mehrere, in Richtung der Verstellung - gemäß Doppelpfeil 15 - aneinander gereihter Stellplätze 27 vorzusehen.As can be seen from the exemplary embodiment shown, it is of course also possible, with a correspondingly long adjustment path of the tower-shaped housing 11 in the linear guide device 8, to provide a plurality of parking spaces 27 lined up in the direction of the adjustment - according to the double arrow 15.

Der Stapelschacht 3 wird nach dem gezeigten Ausführungsbeispiel durch ebenflächige, senkrecht zu einer Oberfläche 34 ausgerichtete Schachtbegrenzer 35, zum Beispiel blechförmige Wandteile 36, gebildet. Zur Positionierung der Schachtbegrenzer 35 sind in der Oberseite 34 der Transportträger 2 in einer rasterförmigen Anordnung Aufnahmenuten 37 vorgesehen, die bevorzugt zueinander in einem rechten Winkel verlaufen, und parallel zu Seitenflächen 38 der Tragplatte 28 angeordnet sind und jeweils einander gegenüber liegend vorgesehene Aufnahmenuten 37 in einem gleichen Normalabstand zum Flächenmittelpunkt 33 angeordnet sind.The stacking shaft 3 is formed according to the embodiment shown by planar, perpendicular to a surface 34 aligned Schachtbegrenzer 35, for example, sheet-shaped wall parts 36. To position the Schachtbegrenzer 35 receiving grooves 37 are provided in the top 34 of the transport carrier 2 in a grid-shaped arrangement, which are preferably at right angles to each other, and are arranged parallel to side surfaces 38 of the support plate 28 and each provided opposite grooves 37 in one same normal distance to the surface center 33 are arranged.

Durch den rechtwinkeligen Verlauf der Aufnahmenuten 37 wird einfach erreicht, dass zwei aneinandergrenzende Wandteile 36 durch Einführen in zwei benachbarte Aufnahmenuten 37 ohne Positionieraufwand exakt rechtwinkelig zueinander ausgerichtete Anschlagebenen für, z.B. einen rechtwinkeligen Eckbereich aufweisende Werkteile 4 bilden.Due to the rectangular course of the receiving grooves 37, it is easily achieved that two adjoining wall parts 36, by insertion into two adjacent receiving grooves 37 without positioning effort, are arranged exactly perpendicularly aligned stop planes for, e.g. form a rectangular corner area having factory parts 4.

Ein oder mehrere weitere Wandteile 36 können zur Positionierung der Werkteile 4 im Stapelschacht 3 durch Beistellung eingesetzt werden, die bündig auf der Oberseite 34 der Tragplatte 28 positioniert werden und mittels standardgemäßer Permanentmagnete 39 in Position gehalten werden.One or more further wall parts 36 can be used to position the workpieces 4 in the stacking shaft 3 by provision, which are positioned flush on the top 34 of the support plate 28 and held by means of standard permanent magnets 39 in position.

Selbstverständlich ist es auch möglich, die Tragplatte 28 in einem Raster mit Spannuten zu versehen in denen mit Gewindebohrungen versehenen Nutensteine verstellbar eingesetzt sind und die Wandteile 36 über Schrauben in der Vertikallage und Position entsprechend der Konfiguration der Werkteile 4 auf der Oberseite 34 der Tragplatte 28 zu fixieren.Of course, it is also possible to provide the support plate 28 in a grid with flutes in which provided with threaded holes nuts are adjustably inserted and the wall parts 36 via screws in the vertical position and position corresponding to the configuration of the workpieces 4 on the top 34 of the support plate 28 fix.

In den Fig. 4 und 5 ist eine andere Ausführung der Manipulationseinrichtung 5 der erfindungsgemäßen Vereinzelungsvorrichtung gezeigt. Die Seitenwand 12 des turmförmigen Gehäuses 9 weist die Linearführungseinrichtung 13 für einen in dieser geführten Schlitten 40 auf, der mit einem Mitnehmerfortsatz 41 in einen Innenraum des Gehäuses 9 einragt. Im Mitnehmerfortsatz 41 ist eine Spindelmutter 42 verankert, welche in Antriebsverbindung mit einer in das Gehäuse 9 einragenden Gewindespindel 43 steht. Ein Antrieb 44 für die Gewindespindel 43 wird durch einen auf einer Deckplatte 45 des Gehäuses 9 aufgeflanschten Elektromotor 45, insbesondere einem Servomotor, gebildet, der über eine Leitung 46 mit einer nicht weiters dargestellten Steuereinrichtung der Vereinzelungsvorrichtung verbunden ist. Damit wird die Verstellung des Schlittens 40 und damit der am Schlitten 40 angeordneten, wie bereits vorhergehend beschriebenen Konsole 16 mit den Greiffingern 17 - gemäß Doppelpfeil 18 - erreicht.In the 4 and 5 another embodiment of the manipulation device 5 of the separating device according to the invention is shown. The side wall 12 of the tower-shaped housing 9 has the linear guide device 13 for a guided in this carriage 40, which protrudes with a driver extension 41 in an interior of the housing 9. In Mitnehmerfortsatz 41 a spindle nut 42 is anchored, which is in driving connection with a projecting into the housing 9 threaded spindle 43. A drive 44 for the threaded spindle 43 is formed by a flanged on a cover plate 45 of the housing 9 electric motor 45, in particular a servo motor, which is connected via a line 46 with a not further illustrated control device of the separating device. Thus, the adjustment of the carriage 40 and thus arranged on the carriage 40, as previously described console 16 with the gripper fingers 17 - according to double arrow 18 - reached.

Die Konsole 16 ist in einer Stirnplatte 47 des Schlittens 40 in einer Schwenkanordnung 48 schwenkbar - gemäß Doppelpfeil 49 - gelagert, wobei ein Schwenkantrieb 50, beispielsweise durch einen elektrisch betriebenen, mit der nicht weiters gezeigten Steuereinrichtung über eine Leitung 51 verbundenen Servomotor 52, gebildet ist.The bracket 16 is pivotally mounted in a front plate 47 of the carriage 40 in a pivot assembly 48 - according to double arrow 49 -, wherein a pivot drive 50, for example, by an electrically operated, with the controller not shown further connected via a line 51 servomotor 52 is formed ,

Der Servomotor 52 ist nach dem gezeigten Ausführungsbeispiel auf einem parallel zur Stirnplatte 47 verlaufenden Schenkel 53 der Konsole 16 aufgeflanscht, wodurch eine drehfeste Verbindung eines Motorgehäuses mit der Konsole 16 erreicht wird. Ein Antriebsstummel 54 des Servomotors 52 durchragt den Schenkel 53 in einer Freistellungsbohrung 55 und ist mit der Stirnplatte 47 des Schlittens 40 drehfest gekuppelt. Damit wird bei Ansteuerung des Servomotors 52 über die Leitung 51 die Schwenkbewegung der Konsole 16 mit den Greiffingern 17 erreicht. Ausreichend erscheint es, eine Schwenkbewegung, ausgehend von einer waagrechten Stellung der Tragarme 21, mit +/- 90° festzulegen. Durch die in den Fig. 4 und 5 gezeigte Ausführung wird zusätzlich zu der X- Achse und Y- Achse eine dritte Bewegungsachse an der Manipulationseinrichtung 5 erreicht die es ermöglicht den aus dem Stapelschacht entnommenen Werkteil 4 aus einer zur Aufstandsfläche parallelen Übergabeposition 56 für ein Greifmittel, z.B. eine Greifzange 57, einer nicht weiter dargestellten Beschickungseinrichtung, z.B. einem Mehrachsroboter, in eine vertikale Lage zu schwenken und damit gegebenenfalls eine Übergabeposition zur vereinfachten Aufnahme des Werkteils 4 durch eine Greifvorrichtung eines Roboters zu erreichen.The servomotor 52 is flanged in the embodiment shown on a parallel to the end plate 47 extending leg 53 of the bracket 16, whereby a rotationally fixed connection of a motor housing with the bracket 16 is achieved. A drive stub 54 of the servomotor 52 extends through the leg 53 in a release hole 55 and is rotatably coupled to the end plate 47 of the carriage 40. Thus, upon actuation of the servomotor 52 via the line 51, the pivoting movement of the console 16 with the gripper fingers 17 is achieved. It seems sufficient to define a pivoting movement, starting from a horizontal position of the support arms 21, with +/- 90 °. By in the 4 and 5 As shown, in addition to the X-axis and Y-axis, a third axis of movement at the manipulation device 5 is reached, which allows the workpiece part 4 removed from the stacking shaft to be transferred from a transfer position 56 parallel to the contact surface for a gripping means, eg a gripper 57, one not further shown feeding device, such as a multi-axis robot to pivot in a vertical position and thus optionally to achieve a transfer position for simplified recording of the workpiece 4 by a gripping device of a robot.

Den Fig. 4 und 5 ist noch weiters zu entnehmen, dass es selbstverständlich möglich ist, den bzw. die Greiffinger 17 mit einem über eine Leitung 58 mit der nicht weiter dargestellten Steuereinrichtung verbundenen Kraftmesssensor 59 zu versehen und damit nach Aufnahme des Werkteils 4 eine Gewichtskontrolle mit in der Steuereinrichtung hinterlegter Gewichtswerte vorzunehmen um damit eine Aufnahme zweier aneinander haftender Werkteile 4 - wie es beispielsweise durch eine wirkende Adhäsionskraft bzw. Verklebung, Verhakung möglich ist - zu detektieren und in einem derartigen Fall die den Funktionslauf störende Doppelblechaufnahme durch Abgabe der aufgenommenen Werkteile 4 in einen Sammelbehälter wirkungsvoll zu beseitigen.The 4 and 5 Furthermore, it can be seen that it is of course possible to provide the gripping finger 17 with a force measuring sensor 59 connected via a line 58 to the control device, not shown, and thus after checking the workpiece 4 with a weight control with weight values stored in the control device in order to detect a recording of two mutually adhering parts 4 - as it is, for example, by an effective adhesive force or bonding, entanglement is possible - to effectively remove in such a case, the function run disturbing double sheet holder by delivering the recorded parts 4 in a collecting container ,

Zur Feststellung einer "Doppelblechaufnahme" sind aber auch aus dem Stand der Technik die Anwendung einer Kapazitätsmessung oder Messung des Schwingungsverhaltens des aufgenommenen Werkteils bekannt und einsetzbar.However, in order to establish a "double sheet reception", the application of a capacitance measurement or measurement of the vibration behavior of the recorded part of the work is also known and usable from the prior art.

Es wird weiter darauf verwiesen, dass ein derartiger elektrisch betätigter Spindeltrieb, wie in den Fig. 4 und 5 für die Y- Achse beschrieben, selbstverständlich auch als Stellantrieb für die Verstellung des turmförmigen Gehäuses 9 in der zu den Fig. 1 bis 3 beschriebenen X- Achse angewendet werden kann.It is further referred to that such an electrically operated spindle drive, as in the 4 and 5 described for the Y axis, of course, as an actuator for the adjustment of the tower-shaped housing 9 in the to Fig. 1 to 3 described X-axis can be applied.

Erwähnt sei weiter, dass auch der Einsatz einer Trennvorrichtung, wie sie aus dem Stand der Technik bekannt sind, möglich ist. Eine derartige Vorrichtung kann der Manipulationseinrichtung 5 im Bewegungsbereich der Greifvorrichtung 14 beigestellt sein und kann z.B. damit eine Trennung eines anhaftenden Werkteils durch Magnetwirkung oder mechanisch herbeigeführt werden.It should also be mentioned that the use of a separating device, as known from the prior art, is possible. Such a device may be provided to the manipulation device 5 in the range of movement of the gripping device 14 and may be e.g. so that a separation of an adhering part of the work by magnetic effect or mechanically induced.

In der Fig. 6 ist nun die Positionierung des Transportträgers 2 in Bezug auf die Manipulationseinrichtung 5 zur Bildung einer Referenzlage zumindest eines auf dem Transportträger 2 angeordneten Stapelschachtes 3 dargestellt und anhand dieser Figur erläutert.In the Fig. 6 is now the positioning of the transport carrier 2 with respect to the manipulation device 5 for forming a reference position of at least one arranged on the transport carrier 2 stacking shaft 3 is shown and explained with reference to this figure.

Im gezeigten Ausführungsbeispiel sind der Manipulationseinrichtung 5 mit der Greifvorrichtung 14 zwei der Stellplätze 27 für je einen Transportträger 2 mit rechteckigen Abmessungen, bevorzugt in einem halben Format einer Euro- Palette, zugeordnet. Auf den Transportträgern 2 ist nach der Darstellung jeweils ein durch die rasterförmig angeordneten Aufnahmenuten 37 in einer in Bezug auf die rechwinkelig aneinander grenzenden Seitenflächen 37 in definierter Lage angeordneter Stapelschacht 3 vorgesehen. Selbstverständlich ist auch die Anordnung weiterer Stapelschächte 3 auf dem Transportträger 2 möglich.In the illustrated embodiment, the manipulation device 5 with the gripping device 14 two of the slots 27 for each transport carrier 2 with rectangular dimensions, preferably in half a format of a Euro pallet assigned. On the transport carriers 2, according to the representation, a stacking shaft 3 arranged in a defined position relative to the rake-shaped side surfaces 37 is provided in each case by the receiving grooves 37 arranged in the form of a grid. Of course, the arrangement of further stacking shafts 3 on the transport carrier 2 is possible.

Die Linearführungseinrichtung 8 mit dem Linearantrieb 10 der Manipulationseinrichtung 5 ist auf der Aufstandsfläche 6 befestigt und damit eine X- Achse 60 für die Verstellung der Greifvorrichtung 14 vorgegeben, wie auch ein Verstellweg - gemäß Doppelpfeil 15 - Richtung der X- Achse 60 durch die Linearfiihrungsvorrichtung 8 bzw. durch einen Abstand 61 einander gegen über liegender, einstellbarer Endanschläge 62, 63 vorgegeben ist.The linear guide device 8 with the linear drive 10 of the manipulation device 5 is mounted on the footprint 6 and thus an X-axis 60 for the adjustment of the gripping device 14 given, as well as an adjustment - according to double arrow 15 - direction of the X-axis 60 by the Linearfiihrungsvorrichtung. 8 or by a distance 61 is given to each other over lying, adjustable end stops 62, 63.

In Bezug auf die X- Achse 60 sind nun nach dem Ausführungsbeispiel in paralleler Ausrichtung einer Mittelachse 64 auf der Aufstandsfläche 6 Positioniermittel 65 angeordnet welche die Zentrieraufnahmen 32 für den Eingriff der Positionierfortsätze 31 zweier benachbarter, bevorzugt in den Eckbereichen 29 angeordneter Abstandselemente 30 je Transportträger 2 ausbilden. Damit sind die Transportträger 2 in einer Lage ausgerichtet bei der eine der Seitenflächen 38 parallel und in einer vorgegebenen Distanz 66 zu der X- Achse 60 und die weitere Seitenfläche 38 im rechten Winkel dazu verläuft.With regard to the X-axis 60 positioning means 65 are now arranged according to the embodiment in parallel alignment of a central axis 64 on the footprint 6 which the centering 32 for engaging the positioning projections 31 of two adjacent, preferably arranged in the corner regions 29 spacers 30 per transport carrier form. Thus, the transport carrier 2 are aligned in a position in which one of the side surfaces 38 extends parallel and at a predetermined distance 66 to the X-axis 60 and the further side surface 38 at right angles thereto.

Die Anordnung der Positioniermittel 65 zur Erreichung einer Referenzlage des Stapelschachtes 3, bei der ein in einer neutralen Mittelstellung auf der Konsole 16 justierter Greiffinger 17 etwa zentral in den Stapelschacht 3 eintaucht, in Bezug auf die Manipulationseinrichtung 5, wird durch die Anordnung der Positioniermittel 65 relativ zur Lage der X- Achse 60 der Linearführungseinrichtung 8 sowie einer Endlage 67 in Richtung der X- Achse 60 des Greiffingers 17 und der vorgegebenen Distanz 66 unter Berücksichtigung der maßlichen Ausgestaltung des Transportträgers 2, wie einer Länge 68, Breite 69 sowie einem Seitenabstand 70 der Aufnahmenuten 37 und der Anordnung der Abstandselemente 30 in den Eckbereichen 39.The arrangement of the positioning means 65 to achieve a reference position of the stacking shaft 3, in which a in a neutral center position on the console 16 adjusted gripping finger 17 approximately centrally immersed in the stacking shaft 3, with respect to the manipulation device 5, 65 is relatively by the arrangement of the positioning to the position of the X-axis 60 of the linear guide device 8 and an end position 67 in the direction of the X-axis 60 of the gripping finger 17 and the predetermined distance 66, taking into account the dimensional design of the transport carrier 2, such as a length 68, width 69 and a lateral distance 70 of Receiving grooves 37 and the arrangement of the spacer elements 30 in the corner regions 39th

In Kenntnis der maßlichen Ausgestaltung kann die Positionierung der Positioniermittel 65 in Abhängigkeit von der Lage der Handhabungseinrichtung 5 bzw. der Linearführungseinrichtung 8 über eine errechnete X- Koordinate des Flächenmittelpunktes 33 des Transportträgers 2 oder eines Schnittpunktes 71 der benachbarten Seitenflächen 38 in Bezug auf die Endlage 67 der Greifvorrichtung 14 erfolgen.Knowing the dimensional configuration, the positioning of the positioning means 65 in dependence on the position of the handling device 5 or the linear guide device 8 via a calculated X coordinate of the center of area 33 of the transport carrier 2 or an intersection 71 of the adjacent side surfaces 38 with respect to the end position 67th the gripping device 14 done.

Es wird auch noch auf eine vorteilhafte Ausbildung verwiesen wonach bei einer Auslegung der Vereinzelungsvorrichtung 1 mit zwei Stellplätzen 27 ein Verstellweg der Linearführungseinrichtung 8 zwischen der Endlage 67 der Greifvorrichtung 14 und einer davon distanzierten Endstellung etwa der Breite 69 des Transportträgers 2, zuzüglich eines minimalen Abstandes zwischen den Transportträgern 2 beträgt.It is also referred to an advantageous embodiment according to which in a design of the separating device 1 with two parking spaces 27 an adjustment of the linear guide device 8 between the end position 67 of the gripping device 14 and a distal end position about the width 69 of the transport carrier 2, plus a minimum distance between the transport carriers 2 amounts.

Damit erfolgt, wie noch wie den Fig. 1 bis 3 zu entnehmen, jeweils in einer der Endlagen, ohne erforderlicher Zwischenpositionierung der Greifvorrichtung 14, die Aufnahme des Werkteils 4 aus dem Stapelschacht 3 durch Aufsetzen des bzw. der Greifmittel, z.B. Vakuumsauger, Magnet etc. auf den zu vereinzelnden Werkteil 4 im Stapelschacht 3 und anschließendem Hochfahren der Greifvorrichtung 14 in eine obere Endlage - der Y- Achse -, wodurch der Werkteil über dem Stapelschacht 3 positioniert ist. Danach ist ein Verfahren der Greifvorrichtung 14 mit dem vereinzelten Werkteil 4 in eine der beiden Endlagen - der X-Achse - zweckmäßig die für die Übergabeposition 56, zur Übernahme des Werkteils durch eine Beschickungseinrichtung, z.B. eines Mehrachsroboters für die Bedienung einer Biegepresse, definiert ist wodurch der Bewegungsablauf des Roboters vereinfacht und der Programmier- und Steuerungsaufwand reduziert wird.This is done, as well as the Fig. 1 to 3 can be seen, in each case in one of the end positions, without required intermediate positioning of the gripping device 14, the recording of the workpiece 4 from the stacking shaft 3 by placing the or the gripping means, eg vacuum suction, magnet, etc. on the workpiece 4 to be separated in the stacking shaft 3 and then Starting the gripping device 14 in an upper end position - the Y-axis -, whereby the work piece is positioned above the stacking shaft 3.
