Diese Aufgabe wird gelöst mit einer Fördereinrichtung aufweisend die Merkmale von Anspruch 1. Die Ansprüche 2 bis 12 beziehen sich auf weitere, vorteilhafte Ausgestaltung der Fördereinrichtung. Die Aufgabe wird weiter gelöst mit einem Fördersystem aufweisend die Merkmale von Anspruch 13, mit einer Führungsschiene aufweisend die Merkmale von Anspruch 14.This task is solved with a conveyor having the features of claim 1. Claims 2 to 12 refer to another advantageous embodiment the conveyor. The task is solved further with a conveyor system having the characteristics of Claim 13, with a guide rail having the features of claim 14.

Die Aufgabe wird insbesondere gelöst mit einer Fördereinrichtung umfassend eine Führungsschiene sowie zumindest ein an der Führungsschiene geführtes und in einer Förderrichtung angetriebenes Transportmittel, wobei ein bezüglich der Führungsschiene fest angeordnetes ferromagnetisches Flussleitorgan einen Magnet umfasst, und das Transportmittel je zwei gegenseitig beabstandete, ferromagnetische Flussleitteile aufweist, welche derart ausgebildet und angeordnet sind, dass sich einerseits zwischen einem am Transportmittel lösbar anliegenden, ferromagnetischen Ankerteil ein magnetischer Kreis ausbildet, und dass andererseits die Flussleitteile sowie das Flussleitorgan unter Ausbildung eines Luftspaltes derart gegenseitig angepasst angeordnet sind, dass die beiden Flussleitteile mit dem Flussleitorgan einen magnetischen Kreis ausbilden, um eine magnetisch erzeugte Anziehungskraft auf das Ankerteil zu bewirken.The task is solved in particular with a conveyor comprising a guide rail as well, at least one guided on the guide rail and in one conveying direction powered means of transport, one with respect the guide rail fixed ferromagnetic Flow guide includes a magnet, and the means of transport two mutually spaced, ferromagnetic Has flow control parts, which are designed in this way and are arranged that on the one hand between one ferromagnetic detachably attached to the means of transport Anchor part forms a magnetic circle, and that on the other hand, the river control parts and the river guide organ mutually forming an air gap are arranged so that the two parts of the river form a magnetic circuit with the flow guide, a magnetically generated attraction to the To effect anchor part.

Die Fördereinrichtung umfasst eine Führungsschiene mit einer Mehrzahl von an der Führungsschiene geführten Transportmittel. Diese Transportmittel weisen in einer bevorzugten Ausführungsform eine Lastseite auf, an welcher ein zu transportierender Gegenstand anbringbar ist oder auf welche ein zu transportierender Gegenstand abstellbar ist. Jedes Transportmittel umfasst mehrere Gleit- oder Rollmittel, welche insbesondere als ein Stift oder als ein Rad ausgestaltet sind, welche beispielsweise in gegenüberliegend angeordnete V-förmig ausgestaltete Nuten einer Führungsschiene eingreifen, so dass das Transportmittel durch die Führungsschiene in einer Förderrichtung geführt ist. Das Transportmittel weist zwei gegenseitig beabstandet angeordnete ferromagnetische Flussleitteile auf, welche an deren einem Ende zur Lastseite münden und an deren anderen Ende unter Ausbildung eines Luftspaltes zu einem ferromagnetischen Flussleitorgan ausgerichtet angeordnet sind. Dieses Flussleitorgan umfasst ein Magnet, welches beispielsweise als ein Permanentmagnet ausgestaltet ist. Somit bilden das Magnet, die Flussleitorgane sowie die Flussleitteile einen magnetischen Kreis aus. Wird ein ferromagnetisches Ankerteil auf die Lastseite aufgelegt, so wird dieses durch die magnetisch erzeugte Anziehungskraft vom Transportmittel angezogen und dadurch am Transportmittel gehalten.The conveyor device includes a guide rail a plurality of transport means guided on the guide rail. These means of transport have a preferred Embodiment a load side on which a object to be transported is attachable or on which an object to be transported can be parked. Each means of transport comprises several sliding or rolling means, which in particular as a pen or as a wheel are configured, for example in opposite arranged V-shaped grooves of a guide rail intervene so that the means of transport through the guide rail is guided in a conveying direction. The means of transport has two mutually spaced apart arranged ferromagnetic flux control parts, which on one end to the load side and at the other End forming an air gap to a ferromagnetic River guide organ are arranged aligned. This flux guide comprises a magnet, which for example is designed as a permanent magnet. Thus, the magnet, the flow guide organs and the Flow control parts from a magnetic circuit. Becomes a ferromagnetic armature part placed on the load side, so this is due to the magnetically generated attraction attracted to the means of transport and thereby to the means of transport held.

Die erfindungsgemässe Fördereinrichtung erlaubt somit einen zu transportierenden Gegenstand beziehungsweise einen ferromagnetischen Ankerteil ansteuerbar über magnetisch wirkende Kräfte mit dem Transportmittel zu verbinden oder auch vom Transportmittel zu trennen. Der zu transportierende Gegenstand kann direkt auf dem Transportmittel aufliegen. Es besteht jedoch auch die Möglichkeit, am ferromagnetischen Ankerteil ein weiteres zum Transport eines Gegenstandes geeignetes Mittel anzuordnen, z.B. ein über dem Ankerteil angeordnetes Tragteil oder ein am Ankerteil hängendes Haltemittel.The conveyor device according to the invention thus allows an object to be transported or a ferromagnetic armature part can be controlled via magnetically acting forces with the means of transport connect or separate from the means of transport. The too item can be transported directly on the means of transport rest. However, there is also the possibility on the ferromagnetic armature part another for transport to arrange a suitable means of an object, e.g. on arranged above the anchor part or a support Anchoring part hanging holding means.

Das in einer bevorzugten Ausführungsform beidseitig einer Führungsschiene angeordnet verlaufende ferromagnetische Flussleitorgan kann sich in Förderrichtung der Führungsschiene über einen längeren Teilabschnitt oder über die gesamte Länge der Führungsschiene erstrecken. Ein derart ausgestaltetes ferromagnetisches Flussleitorgan weist eine Mehrzahl von in Förderrichtung beabstandet angeordnete Magnete auf, so dass der magnetische Kreis an jeder Stelle einen genügend grossen magnetischen Fluss aufweist, um das Ankerteil sicher am Transportmittel zu halten. Somit wird auf ein sich entlang der Führungsschiene in einer Förderrichtung bewegenden Transportmittel an jeder Stelle ein magnetischer Fluss erzeugt, so dass das Ankerteil, welches auf der Lastseite des Transportmittels anliegt, ständig eine anziehende, magnetische Kraft erfährt.In a preferred embodiment, one on both sides Guide rail arranged running ferromagnetic The flow guide can move in the conveying direction of the guide rail over a longer section or over the extend the entire length of the guide rail.

Die Magnete können auch als Elektromagnete ausgestaltet sein, wobei das Elektromagnet zumindest aus einer um das Flussleitorgan gewickelten Spule besteht. Ein Elektromagnet weist den Vorteil auf, dass die Grösse des magnetischen Flusses und dadurch die Grösse der magnetisch erzeugten Anziehungskraft ansteuerbar ist. Ein ferromagnetisches Flussleitorgan kann auch ein Permanentmagnet sowie ein Elektromagnet umfassen, wobei das Elektromagnet derart ansteuerbar ist, dass der Permanentmagnet und der Elektromagnet entweder einen gleichgerichtet sich gegenseitig verstärkenden magnetischen Fluss erzeugen, oder einen entgegengesetzt gerichtet verlaufenden, sich gegenseitig reduzierenden magnetischen Fluss erzeugen.The magnets can also be designed as electromagnets be, the electromagnet at least one around Flow guide wound coil consists. An electromagnet has the advantage that the size of the magnetic Flux and therefore the size of the magnetic generated attraction is controllable. A ferromagnetic Flow guide can also be a permanent magnet as well comprise an electromagnet, the electromagnet being such is controllable that the permanent magnet and the electromagnet either one mutually rectified generate amplifying magnetic flux, or one oppositely directed, mutually generate reducing magnetic flux.

Die erfindungsgemässe Fördereinrichtung ist insbesondere zum Fördern von Druckereiprodukten geeignet. Das Ankerteil kann beispielsweise als schienenführbares Fördermittel ausgestaltet sein, wie dies in der EP-A-1 042 202 offenbart ist. Weitere Ausbildungsformen und Anwendungen der erfindungsgemässen Förderrichtung sind in EP-A-1 042 203 und EP-A-1 042 196 offenbart. The conveyor device according to the invention is in particular suitable for conveying printed products. The anchor part can, for example, as a rail-based funding be designed like this in the EP-A-1 042 202 is disclosed. Further forms of training and applications of the inventive Direction of funding are in EP-A-1 042 203 and EP-A-1 042 196.

Die erste Führungsschiene 1 definiert eine Förderrichtung F, in welcher das Transportmittel 3 vorzugsweise angetrieben gefördert wird. An der ersten Führungsschiene 1 ist ein Flussleitorgan 5 angeordnet, welches aus zwei Flussleitteilen 5a,5b sowie einem Permanentmagnet 4 besteht. Die beiden Flussleitteile 5a,5b sind L-förmig ausgestaltet und fest mit der Führungsschiene 1 verbunden. Die Flussleitteile 5a,5b weisen einen unteren Abschnitt auf, welcher in vertikaler Richtung verläuft, wobei an dessen Enden der Permanentmagnet 4 angekoppelt ist.Fig. 1 shows a cross section through a conveyor 20. A U-shaped first guide rail 1 points to the opposite side surfaces V-shaped grooves on which to guide serve the wheels 3b of a means of transport 3. The first Guide rail 1 defines a conveying direction F, in which preferably drives the means of transport 3 is promoted. On the first guide rail 1 is a Flow guide organ 5 arranged, which consists of two flow control parts 5a, 5b and a permanent magnet 4. The two flow control parts 5a, 5b are L-shaped and firmly connected to the guide rail 1. The river control parts 5a, 5b have a lower section, which in vertical direction, with the ends of the Permanent magnet 4 is coupled.

Das Transportmittel 3 weist einen Grundkörper 3a aus einem nicht ferromagnetischen Material, beispielsweise aus Aluminium oder einem Kunststoff auf. Auf diesem Grundkörper 3a sind zwei L-förmige, gegenseitig beabstandete, ferromagnetische Flussleitteile 3c angeordnet, wobei deren eines Ende 3i zur Lastseite 3h mündet und das andere Ende 3k unter Ausbildung eines Luftspaltes 8a den Flussleitorganen 5a,5b gegenüberliegend angeordnet ist. Zur Ausbildung einer ebenen Lastseite 3h sind die beiden ferromagnetischen Teile 3c mit einem Abdeckteil 3d aus einem nicht ferromagnetischen Material überdeckt, und zwischen den beiden ferromagnetischen Teilen 3c ist zudem ein Mittelteil 3e aus einem nicht ferromagnetischen Material angeordnet, so dass die beiden ferromagnetischen Teile 3c, ohne über die Oberfläche vorzustehen, an der Lastseite 3h münden. Das Flussleitorgan 5, umfassend den Magnet 4 und die Flussleitteile 5a, 5b, sowie der Luftspalt 8a und die beiden Flussleitteile 3c bilden einen magnetischen Kreis 8 aus.The transport means 3 has a base body 3a made of a non-ferromagnetic material, for example Aluminum or a plastic. On this body 3a are two L-shaped, mutually spaced, arranged ferromagnetic flux guide parts 3c, whose one end 3i opens to the load side 3h and the other end 3k with the formation of an air gap 8a the river guide organs 5a, 5b is arranged opposite one another.

Fig.2 zeigt eine Fördereinrichtung 20 mit einem auf der Lastseite 3h anliegenden, ferromagnetischen, als Ankerteil 6 ausgestalteten Körper, welcher den magnetischen Flusskreis 8 schliesst, so dass vom Transportmittel 3 eine magnetisch erzeugte Anziehungskraft Fm auf das Ankerteil 6 bewirkt wird. Auf der Oberfläche 3h des Transportmittels 3 können beliebig geformte Gegenstände 6 angeordnet und über magnetisch wirkende Kräfte fest an den Wagen 3 angekoppelt transportiert werden. Die erfindungsgemässe Fördereinrichtung 20 erlaubt somit einen Gegenstand in Förderrichtung F einer Führungsschiene 1 zu fördern, wobei der Gegenstand 6 jederzeit bzw. an jedem vorher bestimmbaren Ort vom Transportmittel 3 getrennt werden kann, bzw. mit dem Transportmittel 3 verbunden werden kann.2 shows a conveyor 20 with one on the Load side 3h, ferromagnetic, as an anchor part 6 designed body, which the magnetic flux circuit 8 closes so that one of the means of transport 3 magnetically generated attraction force Fm on the armature part 6 is effected. On the surface 3h of the means of transport 3 can arbitrarily shaped objects 6 arranged and over magnetically acting forces are firmly coupled to the carriage 3 be transported. The inventive Conveyor 20 thus allows an object in To convey direction F of a guide rail 1, wherein the object 6 at any time or on everyone beforehand determinable location can be separated from the means of transport 3 can, or be connected to the means of transport 3 can.

Im Ausführungsbeispiel gemäss Fig. 2 ist der magnetische Kreis 8 derart verlaufend angeordnet, dass die Feldlinien im Luftspalt 8a senkrecht zur erzeugten magnetischen Kraft Fm verlaufen. Diese Anordnung weist den Vorteil auf, dass die magnetische Kraft Fm zwischen dem Wagen 3 und dem Ankerteil 6 erzeugt wird, so dass die Räder 3b durch die Kraft Fm keine direkte Belastung erfahren. In einer vorteilhaften Ausführungsform sind die Flussleitteile 5a, 5b des Flussorganes 5 im Bereich des Luftspaltes 8 in Förderrichtung F parallel verlaufend ausgestaltet, so dass für ein Transportmittel 3 die Summe der Breite der beiden Luftspalte 8a konstant bleibt, selbst wenn das Transportmittel 3 sich auf Grund vorhandener Ungenauigkeiten in horizontaler Richtung leicht hin und her bewegt.2 is the magnetic one Circle 8 arranged so that the field lines in the air gap 8a perpendicular to the generated magnetic force Fm run. This arrangement has the advantage that the magnetic force Fm between the carriage 3 and the Anchor part 6 is generated so that the wheels 3b through the Force Fm experienced no direct load. In a advantageous embodiment are the flow control parts 5a, 5b of the flow element 5 in the area of the air gap 8 in Conveying direction F is designed to run parallel, so that for a means of transport 3 the sum of the width of the two Air gap 8a remains constant even if that Means of transport 3 based on existing Inaccuracies in the horizontal direction slightly back and forth moved here.

In einer vorteilhaften Ausführungsform weist die Lastseite 3h eine griffig gestaltete Teiloberfläche auf, um eine zusätzliche Haftreibung auf das Ankerteil 6 zu bewirken.In an advantageous embodiment, the load side 3h a non-slip partial surface to one to cause additional static friction on the anchor part 6.

Die in Fig. 3 dargestellte Seitenansicht zeigt ein Transportmittel 3, welches beidseitig zwei in Förderrichtung F beabstandete Gleitkörper 3b aufweist, welche in der ersten Führungsschiene 1 gleitend gelagert sind. Ein ferromagnetischer Ankerteil 6 ist über magnetisch wirkende Kräfte mit den Transportmittel 3 verbunden. Die Magnete 4 sind in Förderrichtung F beabstandet angeordnet, so dass in Förderrichtung F ständig ein magnetischer Kreis 8 ausgebildet ist und somit in Förderrichtung F ständig eine magnetische Kraft Fm vom Transportmittel 3 auf den Körper 6 erzeugt wird.The side view shown in Fig. 3 shows a means of transport 3, which on both sides two in the conveying direction F spaced sliding body 3b, which in the first Guide rail 1 are slidably mounted. A ferromagnetic Armature part 6 is about magnetically acting forces connected to the means of transport 3. The magnets 4 are in Conveying direction F spaced so that in Direction of conveyance F constantly formed a magnetic circuit 8 and is therefore always in the direction of conveyance F. magnetic force Fm from the means of transport 3 to the body 6 is generated.

Fig. 4 zeigt Magnete 4, welche in Förderrichtung F der ersten Führungsschiene 1 unterschiedlich beabstandet angeordnet sind. Weiter zeigt die Fig. 4 den magnetischen Fluss Φ in Funktion der Schienenlänge, wobei in einem ersten Schienenabschnitt 1a drei Magnete 4 angeordnet sind, welche einen relativ grossen magnetischen Fluss Φ erzeugen, wobei in einem nachfolgenden Schienenabschnitt 1b drei Magnete 4 mit grösserem gegenseitigen Abstand angeordnet sind, so dass sich, im Vergleich zum Schienenabschnitt 1a ein geringerer magnetischer Fluss Φ ergibt. Im Schienenabschnitt 1c sind die Magnete 4 noch weiter beabstandet, so dass sich eine weitere Reduktion des magentischen Flusses Φ ergibt. Im Schienenabschnitt 1d ist kein Magnet 4 mehr vorhanden. Ebenso könnte im Schienenabschnitt 1d kein Flussleitorgan 5 angeordnet sein, so dass kein magnetischer Fluss Φ vorhanden ist. Die Darstellung gemäss Fig. 4 zeigt, wie der magnetische Fluss Φ in Funktion des Ortes entlang der ersten Führungsschiene 1 verändert werden kann. Beispielsweise könnte vorgesehen sein, das ferromagnetische Ankerteil 6 im Schienenabschnitt 1c oder 1d vom Transportmittel 3 zu lösen, wobei in den dem Schienenabschnitt 1d vorgelagerten Schienenabschnitt 1a, 1b, 1c die magnetische Haltekraft Fm schrittweise reduziert wird. Die Magnete 4 können als Permanentmagnete ausgestaltet sein oder auch als Elektromagnete, insbesondere auch als solche, die den magnetischen Fluss Φ anzusteuern und einzustellen erlauben.Fig. 4 shows magnets 4 which in the conveying direction F of the first guide rail 1 spaced differently are arranged. 4 shows the magnetic Flow Φ as a function of the rail length, whereby in one first rail section 1a three magnets 4 arranged which have a relatively large magnetic flux Φ generate, being in a subsequent rail section 1b three magnets 4 with a greater mutual distance are arranged so that, compared to the rail section 1a results in a lower magnetic flux Φ. The magnets 4 are even further in the rail section 1c spaced, so that there is a further reduction in magical flow Φ. In the rail section 1d no magnet 4 left. Likewise, in the rail section 1d no flow guide element 5 can be arranged, so that there is no magnetic flux Φ. The representation 4 shows how the magnetic flux Φ in function changed the location along the first guide rail 1 can be. For example, it could be provided the ferromagnetic armature part 6 in the rail section 1c or 1d to be released from the means of transport 3, in which the Rail section 1d upstream rail section 1a, 1b, 1c gradually reduces the magnetic holding force Fm becomes. The magnets 4 can be used as permanent magnets be designed or as an electromagnet, in particular also as such that the magnetic flux Φ control and adjust allow.

Diese zweite Führungsschiene 2 umfasst zwei Schienenteile 2a, welche L-förmig ausgestaltet sind und deren einer Schenkel als Seitenteil 2e ausgestaltet ist, welches fest mit dem Flussleitteil 5a, 5b verbunden ist. Das Schienenteil 2a mit Seitenteil 2e ist aus einem nicht ferromagnetischen Material, beispielsweise aus Aluminium oder einem Kunststoff gefertigt. Zwischen den beiden Schienenteilen 2a ergibt sich ein Spalt 2b, welcher zur Führung des Gleiters 6 dient. An der oberen Fläche des Schienenteils 2a ist beidseitig ein Führungsteil 2c mit Innenfläche 2d angeordnet, wobei die Innenflächen 2d dazu dienen, den Gleiter 6 bzw. den Gleitkörper 6a in seitlicher Richtung zu führen. Im Ausführungsbeispiel gemäss Fig. 7 ist die zweite Führungsschiene 2 derart ausgestaltet, dass im dargestellten Zustand, in welchem der Gleiter 6 durch die magnetisch wirkenden Kräfte fest mit dem Transportmittel 3 verbunden ist, sich keine gegenseitige Berührung von Gleiter 6 mit der zweiten Führungsschiene 2 ergibt, so dass die zweite Führungsschiene nicht erforderlich wäre. Dazu ist zwischen dem Gleiter 6 und der zweiten Führungsschiene 2 ein genügend grosses Spiel vorzusehen. Der Gleiter 6 ist unten am Transportmittel 3 hängend angeordnet und mit einem Haltemittel 11 verbunden, welches einen Bügel 11a, ein Gelenk 11b sowie zwei Zungen 11c umfasst. Die vom Transportmittel 3 über den magnetischen Kreis 8 auf den Gleiter 6 erzeugte magnetische Kraft Fm genügt, um das Haltemittel 11 sicher mit dem Transportmittel 3 zu verbinden.
