Abstract

A conveyor for workpieces, in particular for workpiece carriers, comprises two parallel transporting rails (1, 2) and a cross-belt (3) arranged between these two. To allow the transfer of a workpiece carrier from a transporting rail (1) to the cross-belt (3), the carrier frame (14, 15, 16, 17) of the latter crosses the inner roller system (10, 11) of the transporting rails (1, 2) and bridges the clearance between the roller systems (10, 11) and the belt conveyors (4, 5) of both transporting rails. The cross-belt (3) is linked to two hub devices (25, 26) which can be driven independently of each other and which allow setting of the cross-belt (3) at various different vertical positions in relation to the transport rails (1, 2).

Description

Fördereinrichtung zum Transport von WerkstückenConveyor for the transport of workpieces
Stand der TechnikState of the art
Die Erfindung geht aus von einer Fördereinrichtung nach der Gattung des Hauptanspruchs. Bei bekannten flexihlen Transport- und Montagesystemen sind mehrere, in einer Ehene parallel zueinander angeordnete Transport- bzw. Montagebahnen üher rechtwinkelig zu diesen angeordneten Querförderern miteinander verbunden. Mittels sogenannter Üherschieber werden die Werkstückträger von einer Transportbahn auf den hierzu rechtwinkelig laufenden Querförderer geschehen. Die Üherschieber bestehen aus seitlich der Bahnen angeordneten Hydraulik- oder Pneumatikeinrich- tungen, deren horizontal ausfahrende Stößel das Werkstück bzw. dessen Träger von der Transportbahń auf den Querförderer schieben. Durch die DE-OS 30 12 355 ist eine Vorrichtung zum Umsetzen von Werkstückträgern, Werkstücken oder dergleichen hei zueinander quer oder parallel angeordneten Transportbändern bekannt geworden, bei welcher im Freiraum zwischen den Bändern einer Doppelgurt-Bandanlage eine Umsetzeinrichtung mit wenigstens einem rechtwinkelig zum Doppelgurthand verlaufenden Umsetzhand angeordnet ist. Diese Ums et zeinr ic htung kann an Kreuzungs stel len von quer zueinander verlaufenden Bandanlagen eingesetzt werden und ermöglicht einen problemlosen Ühergang der Werkstückträger von einem Transporthand zum anderen. Die Vorrichtung läßt sich auch zum Umsetzen von Werkstückträgern hei parallel zueinander verlaufenden Transportbändern verwenden, jedoch müssen hierbei die Transportbänder bzw. Transportbahnen unmittelhar nebeneinander gestellt werden.The invention relates to a conveyor according to the preamble of the main claim. In known flexible transport and assembly systems, a plurality of transport or assembly tracks arranged parallel to one another in an Ehene are interconnected at right angles to these transverse conveyors. The workpiece carriers are passed from a transport track onto the cross conveyor running at right angles to this by means of so-called overshifters. The transfer valves consist of hydraulic or pneumatic devices arranged on the side of the tracks, the horizontally extending plungers of which push the workpiece or its carrier from the conveyor onto the cross conveyor. From DE-OS 30 12 355 a device for transferring workpiece carriers, workpieces or the like to each other transversely or parallel arranged conveyor belts has become known, in which in the space between the belts of a double belt conveyor system a transfer device with at least one transfer hand running at right angles to the double belt hand is arranged. This conversion can take place at the intersection len of transverse conveyor systems are used and enables a smooth transition of the workpiece carrier from one transport hand to the other. The device can also be used for transferring workpiece carriers in parallel conveyor belts, but in this case the conveyor belts or conveyor tracks must be placed directly next to one another.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Fördereinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß der Querfδrderer zugleich die Funktion von Umsetzern übernimmt, wobei ein Umsetzen sowohl von der einen als auch von der anderen Transporthahn her möglich ist. Somit lassen sich mehrere Möglichkeiten des Transports von Werkstücken bzw. Werkstückträgern mit der Einrichtung durchführen. Insgesamt ergibt sich durch die Verwendung des erfindungsgemäßen Querförderers ein kostengünstiger, übersichtlicher und funktionsicherer sowie flexihler Aufbau der Anlage, da der Querförderer beliehige Abstände zwischen zwei parallelen Transportbahnen zu überbrücken vermag.The conveyor device according to the invention with the characterizing features of the main claim has the advantage that the Querfδrderer at the same time takes over the function of converters, implementation being possible from one as well as from the other transport tap. This means that several options for transporting workpieces or workpiece carriers can be carried out with the device. Overall, the use of the cross conveyor according to the invention results in a cost-effective, clear and functionally reliable and flexible construction of the system, since the cross conveyor can bridge any distances between two parallel transport tracks.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegehenen Fördereinrichtung möglich. Eine besonders vorteilhafte Aushildung der Kreuzungsstelle zwischen Querfδrderer und Transportbahnen besteht darin, daß die die Rollensysteme tragenden Schienen der Transportbahnen mit Aussparungen zum Durchtritt des Tragrahmens des Querförderers versehen sind. Vorteilhaft ist weiterhin, daß die am Tragrahmen des Querfδrderers angreifende Hubeinrichtung auf drei Vertikalstel lungen des Tragrahmens einstellbar ist. Dadurch können die Werkstücke bzw. deren Träger entweder beide Umsetzstellen passieren oder sie können an einer Umsetzstelle angehalten werden und schließlich an der einen oder anderen Umsetzstelle an den Querförderer übergehen werden. Die Transportmittel des Querförderers entsprechen zweckmäßigerweise denjenigen der Transportbahnen. Hierzu hat der Tragrahmen des Querfδrderers zwei parallele Schienen von denen die eine Schiene Umlenkrollen für ein endloses Gurthand trägt, während an der anderen Schiene ein Rollensystem gelagert ist. Zum Anhalten der Werkstückträger ist die in Bewegungsrichtung der zugeführten Werkstücke erste Schiene des Tragrahmens im Bereich der Transportbahn als Anschlag ausgebildet.The measures listed in the subclaims enable advantageous further developments and improvements of the conveyor device addressed in the main claim. A particularly advantageous training of the crossing point between cross conveyor and transport tracks is that the rails of the transport tracks carrying the roller systems are provided with cutouts for the passage of the support frame of the cross conveyor. It is also advantageous that the lifting device acting on the support frame of the transverse conveyor has three vertical positions lungs of the support frame is adjustable. As a result, the workpieces or their carriers can either pass both transfer points or they can be stopped at one transfer point and finally be transferred to the cross conveyor at one or the other transfer point. The means of transport of the cross conveyor suitably correspond to those of the transport tracks. For this purpose, the support frame of the transverse conveyor has two parallel rails, one of which carries deflection pulleys for an endless belt hand, while a roller system is mounted on the other rail. To stop the workpiece carriers, the first rail of the support frame in the direction of movement of the supplied workpieces is designed as a stop in the region of the transport path.

Beschreibung des AusführungsheispielsDescription of the example
Die erfindungsgemäße Fördereinrichtung besteht im wesentlichen aus zwei parallelen Transportbahnen 1, 2 und einem diese verbindenden Querförderer 3. Die beiden parallelen Transportbahnen 1, 2 haben je ein außenliegendes, angetriebenes Gurtband 4 bzw. 5, das über Umlenkrollen 6 bzw. 7 läuft, die in Profilschienen 8 bzw. 9 mit recht ecki gem Querschnitt gelagert sind. Die Antriehsmittel für die Gurtbänder 4 , 5 sind der Übersichtlichkeit wegen nicht dargestellt. Außerdem haben die Transportbahnen 1, 2 je ein innenliegendes Rollensystem mit Auflage- und Fuhrungs- rollen 10 hzw. 11 für nicht gezeigte Werkstückträger. Die Rollen 10, 11 sind mit geringem Ahstand voneinander an je einer Winkelschiene 12 bzw. 13 gelagert. Die Profilschiene und die Winkelschiene einer jeden Transporthahn sind auf gleicher Höhe liegend an einem nicht dargestellten Gestell befestigt und verlaufen in einem durch Stege oder dergleichen vorgegebenen Ahstand parallel zueinander. Die Werkstückträger liegen auf den Gurtbändern 4 hzw. 5 und auf den mit einseitig angebrachten Schultern versehenen Rollen 10 hzw. 11 auf und werden mit einer durch den Vorschub der Gurtbänder 4 , 5 vorgegebenen Geschwindigkeit transportiert. Die Transportrichtung der beiden Bahnen 1, 2 ist durch Pfeile markiert und kann entgegengesetzt oder gleichlaufend sein.The conveyor device according to the invention essentially consists of two parallel transport tracks 1, 2 and a cross conveyor 3 connecting them. The two parallel transport tracks 1, 2 each have an external, driven belt webbing 4 or 5, which runs over deflection rollers 6 and 7, which in Profile rails 8 and 9 are stored with a right corner cross section. The Antriehsmittel for the straps 4, 5 are not shown for clarity. In addition, the transport tracks 1, 2 each have an internal roller system with support and guide roll 10 hzw. 11 for workpiece carriers, not shown. The rollers 10, 11 are mounted on a respective angular rail 12 or 13 at a small distance from each other. The profile rail and the angle rail of each transport tap are attached to a frame (not shown) at the same height and run parallel to one another at a predetermined distance defined by webs or the like. The workpiece carriers lie on the belt straps 4 hzw. 5 and on the rollers provided with one-sided shoulders 10 hzw. 11 and are transported at a speed predetermined by the advance of the belt straps 4, 5. The direction of transport of the two tracks 1, 2 is marked by arrows and can be opposite or in the same direction.
Die heiden Transportbahnen 1, 2 sind durch den bereits erwähnten Querförderer 3 miteinander verbunden, der den Ahstand zwischen den Bahnen überbrückt und mit dessen Hilfe Werkstückträger von der Bahn 1 auf die Bahn 2 umgesetzt werden können. Im einzelnen hat der Querförderer 3 einen Tragerahmen aus zwei parallel zueinander angeordneten Schienen 14, 15, die durch zwei Stege 16, 17 miteinander verbunden sind. Die Schiene 1 4 ist als Profilschiene mit rechteckigem Querschnitt ausgebildet und mit einem über Umlenkrollen laufenden Gurtband 18 versehen. Dieses Band wird durch einen am Tragerahmen, verankerten, Motor 19 über eine Rolle 19a angetrieben. Die Schiene 15 ist eine Winkelschiene, an welcher mit geringem Abstand voneinander Auflage- und Führungsrollen 20 für die Werkstückträger gelagert sind. Der Querfδrderer 3 und die Transportbahnen 1, 2 haben somit einen identischen Aufhau. Wie aus der Zeichnung ersichtlich, kreuzen die Schienen 14, 15 mit dem Gurtband 18 hzw. den Rollen 20 die innenliegenden Rollensysteme 10, 11 und üherbrücken den Freiraum zwischen diesen Rollensystemen und den außenliegenden, die Gurthänder 4 hzw. 5 tragenden Schienen 8, 9 der beiden Transportbahnen 1, 2. Hierzu sind die Winkelschienen 12, 13 mit Aussparungen hzw. Trennungen 21, 22 bzw. 23. 24 für den Durchtritt der Schienen 14, 15 des Querförderers 3 versehen.The heath transport tracks 1, 2 are connected to one another by the cross conveyor 3 already mentioned, which bridges the gap between the tracks and with the aid of which workpiece carriers can be transferred from track 1 to track 2. In particular, the cross conveyor 3 has a support frame made of two rails 14, 15 arranged parallel to one another, which are connected to one another by two webs 16, 17. The rail 1 4 is designed as a profile rail with a rectangular cross section and is provided with a webbing 18 running over deflection rollers. This belt is driven by a motor 19 anchored to the support frame via a roller 19a. The rail 15 is an angular rail on which support and guide rollers 20 for the workpiece carriers are mounted at a small distance from one another. The Querfδrderer 3 and the transport tracks 1, 2 thus have an identical structure. As can be seen from the drawing, the rails 14, 15 cross with the webbing 18, respectively. the rollers 20, the inner roller systems 10, 11 and bridging over the space between these roller systems and the outer, the belt hands 4 hzw. 5 supporting rails 8, 9 of the two transport tracks 1, 2. For this purpose, the angle rails 12, 13 with recesses hzw. Separations 21, 22 and 23, 24 are provided for the passage of the rails 14, 15 of the cross conveyor 3.
Dem Querförderer sind ferner zwei unabhängig voneinander hefätighare Hubeinrichtungen 25, 26 zum vertikalen Bewegen desselben zugeordnet. Diese greifen nahe der beiden Enden des Tragerahmens an den dort angebrachten Querstegen 16, 17 an. Als Hubvorrichtungen dienen vorzugsweise Pneumatik- oder Hydraulikaggregate, welche einen Zylinder 27 hzw. 28 und einen darin geführten Kolben hahen, dessen Kolhenstange 29 bzw. 30 an dem Quersteg 16 hzw. 17 gelenkig befestigt ist.The cross conveyor is also assigned two independently lifting lifting devices 25, 26 for vertical movement of the same. These engage near the two ends of the support frame on the transverse webs 16, 17 attached there. Pneumatic or hydraulic units are preferably used as lifting devices, which hzw a cylinder 27. 28 and a piston guided therein, the piston rod 29 or 30 of which on the crosspiece 16 hzw. 17 is articulated.
Jede Hubeinrichtung ist unabhängig von der anderen auf drei definierte Vertikalstellungen des Querförderers 3 einstellbar. In der unteren Stellung liegen das Gurtband 18 und die Rollen 20 tiefer als die Teile 4 , 10 und 9, 11 der Transportbahnen 1 bzw. 2. In diesem Fall beeinflußt der Querförderer 3 die Transportrichtung der von der Transportbahn 1 oder von der Transportbahn 2 herangeführten Werkstückträger nicht.Each lifting device can be adjusted independently of the other to three defined vertical positions of the cross conveyor 3. In the lower position, the webbing 18 and the rollers 20 are lower than the parts 4, 10 and 9, 11 of the transport tracks 1 and 2. In this case, the cross conveyor 3 influences the transport direction of those brought up by the transport track 1 or by the transport track 2 Workpiece carrier not.
In der Mittelstellung ist der Tragerahmen des Querförderers 3 zumindest im Bereich der Transportbahn 1 von der Hubeinrichtung 25 soweit angehoben, daß ein mit der Winkelschiene verbundener Anschlag 31 in die Bewegungsbahn eines auf der Transportbahn 1 herangeführten Werkstückträgers gelangt und diesen stoppt. In diesem Fall wird der Werkstückträger auf der Transporthahn 1 angehalten, jedoch noch nicht quer dazu weitertransportiert. Die erfindungsgemäße Einrichtung dient somit auch als Stopper oder Vereinzeier für die Werkstückträger.In the central position, the support frame of the cross conveyor 3 is raised at least in the region of the transport path 1 by the lifting device 25 so that a stop 31 connected to the angle rail comes into the movement path of a workpiece carrier brought up on the transport path 1 and stops it. In this case the workpiece carrier is stopped on the transport tap 1, but has not yet been transported transversely to it. The device according to the invention thus also serves as a stopper or separator for the workpiece carriers.
Soll der durch den Anschlag 31 angehaltene Werkstückträger der Transporthahn 2 zugeführt werden, so wird durch entsprechende Ansteuerung. der Hubeinrichtungen 25, 26 der Querförderer 3 in seine ohere Stellung gehracht. Dahei gelangen das Gurthand 18 und die Rollen 20 von unten her zur Anlage an den vom Anschlag 31 angehaltenen Werkstückträger und liehen diesen vom Gύrtband 4 und von den Rollen 10 der Transportbahn 1 ah. Der abgehobene Werkstückträger wird nun von dem Gurtband 18 des Querförderers in Pfeilrichtung verschbhen bis er durch einen mit der Hohlschiene 9 der Transporthahn 2 verbundenen, nicht dargestellten Anschlag gestoppt wird. In dieser Stellung liegt der Werkstückträger über dem Gurtband 5 und den Rollen 11 der Transportbahn 2 und kann durch Absenken des Querfδrderers 3 in seine mittlere Stellung auf die Teile 9, 11 aufgesetzt und antransportiert werden. Während des Umsetzvorgangs wirkt der in die Transportbahn 1 hineinragende Teil der Hohlschiene 14 der Querförderers als Anschlag für auf der Transporthahn 1 herangeführte, weitere Werkstückträger. Sohald der auf dem Querförderer befindliche Werkstückträger den Bereich der Transportbahn 1 verlassen hat, kann das in die Transportbahn hineinragende Ende des Querförderers wieder in die Mittelstellung abgesenkt werden, so daß der nächste Werkstückträger vom Gurtband 4 der Transporthand 1 an den Anschlag 31 des Querförderers herangeführt wird.If the workpiece carrier stopped by the stop 31 is to be fed to the transport tap 2, the appropriate control is used. the lifting devices 25, 26 brought the cross conveyor 3 into its upper position. Dahei the belt hand 18 and the rollers 20 come from below to rest against the workpiece carrier stopped by the stop 31 and borrow it from the belt 4 and from the rollers 10 of the transport path 1 ah. The lifted workpiece carrier is now spanned by the belt 18 of the cross conveyor in the direction of the arrow until it is stopped by a stop (not shown) connected to the hollow rail 9 of the transport tap 2. In this position, the workpiece carrier lies above the belt 5 and the rollers 11 of the transport path 2 and can be placed on the parts 9, 11 and transported by lowering the transverse conveyor 3 into its central position. During the transfer process, the part of the hollow rail 14 of the cross conveyor projecting into the transport path 1 acts as a stop for further workpiece carriers brought up on the transport tap 1. As soon as the workpiece carrier located on the cross conveyor has left the area of the transport path 1, the end of the cross conveyor projecting into the transport path can be lowered again into the middle position, so that the next workpiece carrier is brought from the belt 4 of the transport hand 1 to the stop 31 of the cross conveyor .
Die unabhängig voneinander betätigbaren Kubeinrichtungen 25, 26 können so gesteuert werden, daß der Tragerahmen des Querfδrderes wippenartig bewegt wird, wobei der Tra- gerahmen wechselseitig zwischen seiner mittleren Stellung und seiner oberen Stellung pendelt, wenn ein Quertransport von Werkstückträgern stattfinden soll.The independently operable cubic devices 25, 26 can be controlled in such a way that the carrying frame of the transverse conveyor is moved in a rocker-like manner, the carrying frame reciprocates alternately between its middle position and its upper position when a cross transport of workpiece carriers is to take place.
Es ist auch möglich, mehrere Werkstückträger auf dem Querfδrderer 3 zu speichern, indem die Hubvorrichtung 26 in der der oberen Stellung des Tragerahmens zugeordneten Position helassen und die Huhvorrichtung 25 den Tragerahmen mehrmals zwischen seiner mittleren und seiner oberen Stellung hin- und herhewegt, wodurch mehrere Werkstückträger auf den Querförderer gelangen, ohne von der Transporthahn 2 abtransportiert zu werden. Ebenso ist es möglich, die Funktion der Transporthahnen 1 , 2 zu vertauschen, d.h. die Bahn 2 zum Zubringen und die Bahn 1 zum Abtransport der Werkstückträger zu benutzen. Es ist somit ein Durchlauf, ein Stop, ein Quertransport, eine Vorvereinzelung, eine Vereinzelung und Absetzen von Werkstückträgern auf einer der Förderhahnen möglich. It is also possible to store several workpiece carriers on the transverse conveyor 3 by lifting the lifting device 26 in the position assigned to the upper position of the carrying frame and the hoisting device 25 reciprocating the carrying frame several times between its middle and its upper position, whereby several workpiece carriers get onto the cross conveyor without being transported away from the transport tap 2. It is also possible to interchange the function of the transport cocks 1, 2, i.e. to use the web 2 for feeding and the web 1 for removing the workpiece carriers. A run, a stop, a transverse transport, a pre-separation, a separation and depositing of workpiece carriers on one of the conveyor cocks is thus possible.
