Die Erfindung gemäß Anspruch 1 betrifft eine Vorrichtung zum Fördern von vereinzelten Gegenständen, insbesondere von scheibenförmigen Gegenständen wie Münzen, mit einer Führungsbahn und mit einem in Abstand von der Führungsbahn auf einem Transportarm umlaufenden Förderriemen, wobei der Abstand d eines der Führungsbahn zugewandten Trums des Transportriemens zur Führungsbahn kleiner als die geringste Höhe eines Gegenstandes über der Führungsbahn ist, wobei die Gegenstände von dem der Führungsbahn zugewandten Trum des Förderriemens ergreifbar und auf der Führungsbahn förderbar sind und wobei die Haftreibungs- und/oder Gleitreibungskräfte zwischen den Gegenständen und dem Förderriemen größer sind als die Haftreibungs- und/oder Gleitreibungskräfte zwischen den Gegenständen und der Führungsbahn, sowie Verwendungen einer solchen Vorrichtung. Die im Rahmen der Erfindung förderbaren Gegenstände weisen meist eine scheibenförmige Gestaltung auf, wobei eine Hauptfläche auf der Führungsbahn gleitet und die gegenüberliegende Hauptfläche von dem Förderriemen ergriffen wird. Eine Führungsbahn kann beispielsweise als Sortierplatte ausgebildet sein.The invention according to claim 1 relates to a device for conveying isolated objects, in particular disc-shaped objects such as coins, with a guide track and with a conveyor belt circulating on a transport arm at a distance from the guide track, the distance d of a strand of the transport belt facing the guide track for Guide track is smaller than the lowest height of an object above the guide track, the objects being gripped by the section of the conveyor belt facing the guide track and conveyable on the guide track, and the static friction and / or sliding friction forces between the objects and the conveyor belt being greater than that Static friction and / or sliding friction forces between the objects and the guideway, as well as uses of such a device.

Stand der Technik und Hintergrund der ErfindungPrior art and background of the invention

Eine Vorrichtung des eingangs genannten Aufbaus ist beispielsweise aus der Literaturstelle EP 0616303 B1 zur Förderung von Münzen bekannt. Hierbei weist die den Münzen zugewandte Seite des Transportriemens eine glatte Oberfläche, jedenfalls ohne erkennbare Erhebungen, auf. Der Andruck des Transportriemens an zu transportierende Münzen erfolgt durch eine Vielzahl von in Richtung der Führungsbahn federkraftbeaufschlagten Stützrollen bzw. Riemenrollen, welche entlang des Transportarmes angeordnet sind. Diese Bauweise hat sich zwar grundsätzlich bewährt, weist jedoch eine Mehrzahl von Nachteilen auf. Zunächst ist festzustellen, dass der Montageaufwand für einen Transportarm sowie der Justageaufwand für die einzelnen Stützrollen beachtlich sind. In kinematischer Hinsicht störend ist, dass der Andruck des Transportriemens in den Bereichen zwischen den Stützrollen bzw. Riemenrollen nachlässt, was insbesondere bei der Förderung von Münzen mit sehr stark variierenden Dicken im Fall der dünnen Münzen stören kann. Weiterhin ist die bekannte Anordnung auch in dynamischer Hinsicht komplex aufgrund der vielen federbelastenen Stützrollen, da damit ein System mit ausgeprägten Eigenfrequenzen geschaffen ist, was in Anbetracht der üblichen hohen Fördergeschwindigkeiten Probleme aufwerfen kann. Zur Vermeidung von störenden Schwingungen des Transportriemens gegen die Führungsbahn sind daher bestimmte Transportgeschwindigkeiten zu meiden oder geeignete Dämpfungsmaßnahmen einzurichten. Schließlich stört, dass bei langer Betriebsdauer die Federn der Stützrollen erlahmen können mit der Folge, dass ein sicherer Transport auch dünnster Münzen nicht stets gewährleistet ist.A device of the structure mentioned at the beginning is, for example, from the literature reference EP 0616303 B1 known for the promotion of coins. The side of the conveyor belt facing the coins has a smooth surface, at least without any noticeable elevations. The pressure of the transport belt on the coins to be transported is carried out by a large number of support rollers or belt rollers which are spring-loaded in the direction of the guide track and which are arranged along the transport arm. Although this design has proven itself in principle, it has a number of disadvantages. First of all, it should be noted that the assembly effort for a transport arm and the adjustment effort for the individual support rollers are considerable. From a kinematic point of view, it is disruptive that the pressure of the transport belt decreases in the areas between the support rollers or belt rollers, which can be a problem in the case of thin coins, in particular when conveying coins with very strongly varying thicknesses. Furthermore, the known arrangement is also complex from a dynamic point of view due to the many spring-loaded support rollers, since it creates a system with pronounced natural frequencies, which can pose problems in view of the usual high conveying speeds. In order to avoid disruptive vibrations of the conveyor belt against the guideway, certain transport speeds must therefore be avoided or suitable damping measures must be implemented. Finally, it is annoying that the springs of the support rollers can weaken over long periods of operation, with the result that safe transport of even the thinnest coins is not always guaranteed.

Aus der Literaturstelle EP 1103932 A1 ist ebenfalls eine Vorrichtung des eingangs genannten Aufbaus bekannt und offenbart eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1. Bei der insofern bekannten Vorrichtung wird versucht, die vorstehenden Probleme dadurch zu lösen, dass der Förderriemen als Lamellenriemen ausgeführt ist. Die Praxis hat jedoch gezeigt, dass nicht nur die Herstellung eines solchen dem Verwendungszweck angepassten Lamellenriemens komplex und teuer ist. Hinzu kommt, dass die Lamellen einen sehr hohen Verschleiß (Abrieb) aufweisen und dadurch zu erheblichen Verschmutzungen der Vorrichtung durch den Abrieb führen. Letzteres erhöht den Wartungs- und Reinigungsaufwand in erheblichem Maße.From the literature reference EP 1103932 A1 a device of the type mentioned at the outset is also known and discloses a device according to the preamble of claim 1. In the device known to this extent, an attempt is made to solve the above problems by designing the conveyor belt as a lamellar belt. However, practice has shown that not only the production of such a lamellar belt adapted to the intended use is complex and expensive. In addition, the lamellae show a very high level of wear (abrasion) and thus lead to considerable contamination of the device due to abrasion. The latter increases the maintenance and cleaning effort to a considerable extent.

Aus der Literaturstelle EP 1 813 715 A1 ist eine weitere Vorrichtung zum Fördern von vereinzelten Gegenständen bekannt.From the literature reference EP 1 813 715 A1 a further device for conveying isolated objects is known.

Technisches Problem der ErfindungTechnical problem of the invention

Demgegenüber liegt der Erfindung das technische Problem zugrunde, ein Vorrichtung zum Fördern von vereinzelten Gegenständen zu schaffen, welche montagetechnisch einfach herzustellen ist und dennoch eine zuverlässige Förderung von Gegenständen unterschiedlicher Dicke gewährleistet, und zwar auch nach langer Betriebsdauer und ohne übermäßigen Abrieb bei dem Förderriemen.In contrast, the invention is based on the technical problem of creating a device for conveying isolated objects, which is easy to assemble in terms of assembly and yet ensures reliable conveyance of objects of different thicknesses, even after a long period of operation and without excessive wear on the conveyor belt.

Grundzüge der Erfindung und bevorzugte AusführungsformenPrinciples of the invention and preferred embodiments

Zur Lösung dieses technischen Problems lehrt die Erfindung, daß der Förderriemen einen Schichtaufbau aufweist, mit zumindest einer Stützschicht, einer Mittelschicht und einer Mitnahmeschicht, wobei die Mitnahmeschicht der Führungsbahn und die Stützschicht Riemenrollen und/oder Stützflächen des Transportarmes zugewandt sind, und wobei die Mitnahmeschicht und die Stützschicht Außenschichten des Förderriemens bilden, und dass die Mittelschicht aus einem in Richtung senkrecht zur Führungsbahn stärker elastisch komprimierbaren Werkstoff gebildet ist, als die Stützschicht und die Mitnahmeschicht. Mit der Erfindung lassen sich Gegenstände mit sehr stark variierender Dicke mit sehr hoher Zuverlässigkeit fördern, und zwar ohne diese Vorteile mit einem erhöhten Anfall von unerwünschtem Abrieb von Komponenten, insbesondere vom Förderriemen, zu erkaufen. Weiterhin macht der Einsatz eines erfindungsgemäß aufgebauten Förderriemens die Einrichtung einer Vielzahl von Stützrollen, welche beim erstgenannten Stand der Technik den nicht elastisch komprimierbaren Riemen gegen die Gegenstände drücken müssen, und zwar bei variierender Dicke mit entsprechenden Federwegen, entbehrlich. Dies liegt daran, dass der erfindungsgemäße Förderriemen in Richtungen orthogonal zu seiner Mitnahmeschicht elastisch komprimierbar ist, und zwar um zumindest 0,5 mm seiner Gesamtdicke, bis zu 1 mm und mehr. Es entfällt daher auch die Gefahr der Ermüdung von Federn im Bereich der Riemenrollen. Von besonderem Vorteil ist auch, dass die Erfindung nicht nur zur Horizontalförderung geeignet ist, sondern ebenso zur Schräg- oder Vertikalförderung. Folglich kann die Längserstreckung der Führungsbahn einen beliebigen Winkel zur Horizontalen aufweisen. Insbesondere kann der Winkel der Führungsbahn zur Horizontalen im Verlauf der Führungsbahn veränderlich, vorzugsweise kontinuierlich veränderlich sein. Es sind also neben ebenen Führungsbahnen auch gekrümmte Führungsbahnen möglich.To solve this technical problem, the invention teaches that the conveyor belt has a layer structure with at least one support layer, a middle layer and a driving layer, the driving layer of the guide track and the supporting layer facing belt rollers and / or support surfaces of the transport arm, and the driving layer and the support layer form outer layers of the conveyor belt, and that the middle layer is formed from a material that is more elastically compressible in the direction perpendicular to the guide track than the support layer and the entrainment layer. With the invention, objects with very widely varying thicknesses can be conveyed with a very high level of reliability, without having to buy these advantages with an increased incidence of undesired abrasion of components, in particular from the conveyor belt. Furthermore, the use of a conveyor belt constructed according to the invention makes it unnecessary to set up a large number of support rollers, which in the first-mentioned prior art have to press the non-elastically compressible belt against the objects, with varying thicknesses with corresponding spring deflections. This is due to the fact that the conveyor belt according to the invention is elastically compressible in directions orthogonal to its entrainment layer, specifically by at least 0.5 mm of its total thickness, up to 1 mm and more. There is therefore no risk of the springs becoming fatigued in the area of the belt pulleys. It is also particularly advantageous that the invention is not only suitable for horizontal conveyance, but also for inclined or vertical conveyance. Consequently, the longitudinal extension of the guideway can have any angle to the horizontal. In particular, the angle of the guide path to the horizontal can be variable, preferably continuously variable, in the course of the guide path. In addition to flat guideways, curved guideways are also possible.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Stützschicht und/oder die Mitnahmeschicht aus einem Werkstoff gebildet sind, welcher ausgewählt ist aus der Gruppe bestehend aus oder auf Basis von "Elastomere, Gummi, Natur-Kautschuk, Synthese-Kautschuk, Polyurethan, Polyetherpolyurethan, Polyesterpolyurethan, Polychloropren, Ethylen-Propylen-Dien-Monomer, gummielastische Werkstoffe und Mischungen dieser Werkstoffe".A preferred embodiment of the invention is characterized in that the support layer and / or the driving layer are formed from a material which is selected from the group consisting of or based on "elastomers, rubber, natural rubber, synthetic rubber, polyurethane, Polyether polyurethane, polyester polyurethane, polychloroprene, ethylene-propylene-diene monomer, rubber-elastic Materials and mixtures of these materials ".

Die Mittelschicht kann aus einem Werkstoff gebildet sein, welcher ausgewählt ist aus der Gruppe bestehend aus oder auf Basis von "elastomere Schaumstoffe, Elastomere, Gummi, Natur-Kautschuk, Synthese-Kautschuk, gummielastische Werkstoffe, Moosgummi, Sylomer-Schaum, PUR Weichschaum, NBR Schaum, und Mischungen dieser Werkstoffe".The middle layer can be formed from a material which is selected from the group consisting of or based on "elastomeric foams, elastomers, rubber, natural rubber, synthetic rubber, rubber-elastic materials, foam rubber, Sylomer foam, PUR soft foam, NBR Foam and mixtures of these materials ".

Die Shore A Härte, gemessen nach DIN ISO 7619, der Stützschicht und/oder der Mitnahmeschicht liegt vorzugsweise im Bereich von mehr als 50 bis 100, insbesondere im Bereich von 60 bis 90. Die Shore A Härte, gemessen nach DIN ISO 7619, der Mittelschicht liegt dann vorzugsweise im Bereich von 15 bis 50, insbesondere im Bereich von 25 bis 50.The Shore A hardness, measured in accordance with DIN ISO 7619, of the support layer and / or the driving layer is preferably in the range from more than 50 to 100, in particular in the range from 60 to 90. The Shore A hardness, measured in accordance with DIN ISO 7619, of the middle layer is then preferably in the range from 15 to 50, in particular in the range from 25 to 50.

Im Einzelnen kann vorgesehen sein, dass die Dicke der Stützschicht im Bereich von 1 bis 8 mm, insbesondere 2 bis 6 mm, vorzugsweise von 2 bis 5 mm, beispielsweise von 3 bis 4 mm, liegt, und/oder dass die Dicke der Mittelschicht 100 bis 300%, vorzugsweise 120 bis 200%, der Differenz der Dicken des dünnsten und des dicksten zu fördernden Gegenstandes aufweist. Die Dicke der Mittelschicht kann alternativ definiert im Bereich 1 bis 5 mm, insbesondere 1,5 bis 4,5 mm, vorzugsweise 2 bis 3,5 mm, liegen. Die Dicke der Mitnahmeschicht liegt vorzugsweise im Bereich von 0,1 bis 5 mm, insbesondere 0,3 bis 3 mm, höchstvorzugsweise von 0,3 bis 1,5 mm, beispielsweise von 0,5 bis 1,2 mm.In detail, it can be provided that the thickness of the support layer is in the range from 1 to 8 mm, in particular 2 to 6 mm, preferably from 2 to 5 mm, for example from 3 to 4 mm, and / or that the thickness of the middle layer 100 to 300%, preferably 120 to 200%, of the difference between the thicknesses of the thinnest and thickest objects to be conveyed. The thickness of the middle layer can alternatively be defined in the range 1 to 5 mm, in particular 1.5 to 4.5 mm, preferably 2 to 3.5 mm. The thickness of the entrainment layer is preferably in the range from 0.1 to 5 mm, in particular 0.3 to 3 mm, most preferably from 0.3 to 1.5 mm, for example from 0.5 to 1.2 mm.

Besonders bevorzugt ist es, wenn die Riemenrollen bzw. Stützflächen des Transportarmes in konstantem Abstand zur Führungsbahn im Transportarm gelagert sind, insbesondere mit positionsfesten Drehachsen im Transportarm gelagert sind. Ansonsten ist ergänzend Folgendes zu bevorzugten Ausführungsformen anzumerken.It is particularly preferred if the belt rollers or support surfaces of the transport arm are mounted at a constant distance from the guide track in the transport arm, in particular are mounted in the transport arm with fixed axes of rotation. Otherwise, the following should also be noted regarding preferred embodiments.

Der Förderriemen kann grundsätzlich als rückseitig strukturloser Keilriemen oder Flachriemen ausgebildet sein. Ebenso möglich ist es, wenn der Förderriemen auf der Seite der Stützschicht eine Antriebsverzahnung aufweist. Dann kann der Förderriemen ohne Schlupf mittels einer Zahnriemenscheibe mit mit der Antriebsverzahnung kämmender Scheibenverzahnung angetrieben werden. Aus Gründen der Verhinderung von störenden Dehnungen des Förderriemens kann dieser eine endlos umlaufende Stahldrahteinlage aufweisen. Anstelle von Stahldraht kann auch eine Bewehrung mit anderen Materialien, beispielsweise Gewebefäden oder -Schnüre, eingerichtet sein. Endlos umlaufend bezeichnet einen Draht oder Faden, welcher um mehr als einen ganzen Umfang des Förderriemens, vorzugsweise um zumindest 2 bis 20, beispielsweise 5 bis 15, Umfänge, spiralförmig umlauft. Es versteht sich, dass auch hierbei letztendlich zwei Enden verbleiben, welche jedoch durch mehrere Endlosumläufe voneinander getrennt sind.The conveyor belt can in principle be designed as a V-belt or flat belt without a structure on the back. It is also possible if the conveyor belt has drive teeth on the side of the support layer. The conveyor belt can then be driven without slippage by means of a toothed belt pulley with disk teeth meshing with the drive teeth. To prevent disruptive stretching of the conveyor belt, it can have an endlessly rotating steel wire insert. Instead of steel wire, reinforcement with other materials, for example fabric threads or cords, can also be set up. Endlessly revolving denotes a wire or thread which revolves around more than an entire circumference of the conveyor belt, preferably around at least 2 to 20, for example 5 to 15, circumferences. It goes without saying that here, too, two ends ultimately remain, which, however, are separated from one another by several endless revolutions.

Aufgrund des Nichterfordernisses von federbelasteten Andruckmechaniken für die Riemenrollen (sofern überhaupt vorzusehen) kann der Transportarm vergleichsweise einfach ausgeführt sein. Vorzugsweise weist der Transportarm zumindest ein Führungselement auf, welches im Querschnitt zur Längserstreckung des Transportarmes U- oder H-förmig ist, wobei der Förderriemen beidseitig seitlich, bezogen auf den Förderriemen, durch Stege geführt wird. Anstelle von Riemenrollen (oder zusätzlich hierzu) kann vorgesehen sein, dass der Förderriemen auf einer Stützfläche zwischen den Stegen gleitet. In der Alternative ohne Riemenrollen wäre die Rollenschicht auch als Stützschicht zu bezeichnen. Im Falle des U-förmigen Querschnitts sind die Stege selbstverständlich auf der der Führungsbahn zugewandten Seite angeordnet. Dann läuft der Förderriemen auf der gegenüberliegenden Seite des Transportarmes ohne seitliche Führung, beispielsweise frei schwebend. Zweckmäßigerweise weist der Transportarm endständige Umlenkrollen auf, vorzugsweise stirnzahnradförmig, wobei zumindest eine der Umlenkrollen antreibbar ist. Solche Rollen werden auch Zahnriemenscheiben genannt. Im Einzelnen empfiehlt es sich, dass die Stützfläche eingangsseitig des Transportarms einen keilförmigen Einlaufbereich aufweist. Der Transportarm kann einen Basisträger aufweisen, an welchem vorzugsweise die Riemenrollen und/oder ein Führungselement oder mehrere Führungselemente, vorzugsweise orthogonal zur Führungsbahn justierbar, angeordnet sind. Damit wird eine zuverlässige Einstellung und Aufrechterhaltung des Abstandes d über die gesamte Längserstreckung der Führungselemente gewährleistet. Zudem ist eine Nachjustierung unschwer möglich. Weiterhin empfiehlt es sich, dass zumindest eine Umlenkrolle in Richtung der Längserstreckung des Transportarmes einstellbar und fixierbar ist, wodurch eine Einstellung der Spannung des Förderriemens möglich ist. Zudem kann der Förderriemen dann unschwer soweit entspannt werden, dass er leicht von dem Transportarm abgezogen werden kann.Because there is no need for spring-loaded pressure mechanisms for the belt rollers (if provided at all), the transport arm can be made comparatively simple. The transport arm preferably has at least one guide element which is U- or H-shaped in cross-section to the longitudinal extension of the transport arm, the conveyor belt being guided laterally on both sides by webs relative to the conveyor belt. Instead of belt rollers (or in addition to this) it can be provided that the conveyor belt is on a support surface between the webs slides. In the alternative without belt rollers, the roller layer could also be referred to as a support layer. In the case of the U-shaped cross section, the webs are of course arranged on the side facing the guide track. Then the conveyor belt runs on the opposite side of the transport arm without lateral guidance, for example floating freely. The transport arm expediently has end pulleys, preferably in the shape of a spur gear, at least one of the pulleys being drivable. Such roles are also called toothed belt pulleys. In particular, it is recommended that the support surface has a wedge-shaped inlet area on the input side of the transport arm. The transport arm can have a base carrier on which the belt rollers and / or a guide element or several guide elements are preferably arranged, preferably orthogonally adjustable to the guide track. This ensures that the distance d is reliably set and maintained over the entire longitudinal extent of the guide elements. In addition, readjustment is easily possible. Furthermore, it is recommended that at least one deflection roller is adjustable and fixable in the direction of the longitudinal extension of the transport arm, whereby an adjustment of the tension of the conveyor belt is possible. In addition, the conveyor belt can then easily be relaxed to such an extent that it can be easily pulled off the transport arm.

In Hinblick auf eine gute Zugänglichkeit der Führungsbahn sowie einer Zugänglichkeit zur Justierung der Führungselemente bzw. Riemenrollen sowie zum Wechsel des Förderriemens kann der Transportarm einseitig von der Führungsbahn abschwenkbar eingerichtet sein. Selbstverständlich kann alternativ oder ergänzend der Transportarm insgesamt abnehmbar gestaltet sein. Der Transportarm kann zumindest ein Justierelement zur Einstellung des Abstandes d aufweisen, wodurch nach einer Justierung einer Mehrzahl von Führungselemente bzw. Riemenrollen beispielsweise zur Neueinstellung oder zur Umstellung nicht alle Führungselemente bzw. Riemenrollen einzeln neu justiert werden müssen.With regard to good accessibility of the guide track and accessibility for adjusting the guide elements or belt rollers and for changing the conveyor belt, the transport arm can be designed to be pivotable on one side from the guide track. Of course, alternatively or in addition, the transport arm can be designed to be removable overall. The transport arm can have at least one adjusting element for setting the distance d, whereby after an adjustment of a plurality of guide elements or belt pulleys, for example for readjustment or conversion, not all guide elements or belt pulleys have to be individually readjusted.

Zwischen der Mittenschicht einerseits und/oder der Stützschicht bzw. Mitnahmeschicht andererseits können (müssen aber nicht) noch weitere Schichten eingerichtet sein, bzw. die Stützschicht und/oder die Mitnahmeschicht können mehrschichtig ausgebildet sein. Ebenso kann die Mittelschicht mehrschichtig ausgebildet sein, wobei dann allerdings deren Teilschichten aus einem stärker elastisch komprimierbaren Werkstoff gebildet sein sollten, als jener der Stützschicht und der Mitnahmeschicht. Insbesondere werden dann diese Teilschichten überwiegend beispielsweise aus einem elastischen Schaumstoff gebildet sein; allenfalls eine der Teilschichten kann aber auch nicht bzw. schwer kompressibel ausgeführt sein.Between the middle layer on the one hand and / or the supporting layer or driving layer on the other hand, further layers can (but do not have to) be set up, or the supporting layer and / or the driving layer can be formed in multiple layers. Likewise, the middle layer can have a multilayer design, in which case, however, its sub-layers should be made of a more elastically compressible material than those of the support layer and the entrainment layer. In particular, these sub-layers will then be formed predominantly, for example, from an elastic foam; at most, however, one of the partial layers can also be designed to be incompressible or difficult to compress.

Die Erfindung ermöglicht weiterhin die Verwendung einer erfindungsgemäßen Vorrichtung zur Förderung von Münzen in horizontaler und/oder vertikaler und/oder schräger Richtung, gegebenenfalls mit beispielsweise kreissegmentförmigen Übergangsbereichen.The invention also enables the use of a device according to the invention for conveying coins in the horizontal and / or vertical and / or inclined direction, optionally with, for example, circular segment-shaped transition areas.

Insbesondere kann die erfindungsgemäße Vorrichtung in einer Vorrichtung zum Zählen und/oder Sortieren von Münzen eingesetzt werden. Hierzu wird auf den einschlägigen Stand der Technik verwiesen, sofern dort mit Transportriemen gearbeitet wird. Diese Transportriemen bzw. die zugehörigen Transportarme lassen sich unschwer gegen erfindungsgemäße Vorrichtungen austauschen.In particular, the device according to the invention can be used in a device for counting and / or sorting coins. For this purpose, reference is made to the relevant state of the art, provided that conveyor belts are used there. Leave these transport belts or the associated transport arms easily exchange for devices according to the invention.

Im Folgenden wird die Erfindung anhand von lediglich ein Ausführungsbeispiel darstellenden Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1: eine schematische Ansicht der Erfindung in Teilansicht,
  • Fig. 2: einen erfindungsgemäßen Transportarm,
  • Fig. 3: einen Querschnitt durch eine erfindungsgemäße Vorrichtung und
  • Fig. 4: eine Detailansicht des Gegenstandes der Figur 2.
In the following, the invention is explained in more detail with reference to drawings depicting only one exemplary embodiment. Show it:
  • Fig. 1 : a schematic view of the invention in partial view,
  • Fig. 2 : a transport arm according to the invention,
  • Fig. 3 : a cross section through a device according to the invention and
  • Fig. 4 : a detailed view of the subject of the Figure 2 .

In der Figur 1 erkennt man eine Teilansicht einer Vorrichtung zum Fördern von vereinzelten Münzen 1, mit einer Führungsbahn 2 und mit einem in Abstand d von der Führungsbahn 2 auf einem Transportarm 3 umlaufenden Förderriemen 4, wobei der Abstand d der Abstand eines der Führungsbahn zugewandten Trums 5 des Transportriemens 4 und kleiner als die geringste Höhe eines Gegenstandes 1 über der Führungsbahn 2 ist. Es versteht sich, dass der Abstand d bei nicht komprimierter Mittelschicht bestimmt ist. Die Münzen 1 sind von dem der Führungsbahn 2 zugewandten Trum 5 des Förderriemens 4 ergreifbar und auf der Führungsbahn 2 förderbar (in der Fig. 1 von rechts nach links) und wobei die Haftreibungs- und/oder Gleitreibungskräfte zwischen den Gegenständen 1 und dem Förderriemen 4 größer sind als die Haftreibungs-und/oder Gleitreibungskräfte zwischen den Gegenständen 1 und der Führungsbahn 2. Im Einzelnen wird deutlich, dass der Förderriemen 4 einen Schichtaufbau aufweist, mit zumindest einer Stützschicht 4a, einer Mittelschicht 4b und einer Mitnahmeschicht 4c, wobei die Mitnahmeschicht 4c der Führungsbahn 2 und die Stützschicht 4a Riemenrollen 3a des Transportarmes 3 zugewandt sind, und wobei die Mitnahmeschicht 4c und die Stützschicht 4a Außenschichten des Förderriemens 4 bilden, und dass die Mittelschicht 4b aus einem in Richtung senkrecht zur Führungsbahn 2 stärker elastisch komprimierbaren Werkstoff gebildet ist, als die Stützschicht 4a und die Mitnahmeschicht 4c. Letzteres ist insbesondere im Bereich von Münzen 1 ersichtlich, wo die Mittenschicht 4b komprimiert ist, während die Dicken der Stützschicht 4a und der Mitnahmeschicht 4c praktisch unverändert sind, verglichen mit Bereichen ohne mitgenommenen Münzen 1. Ergänzend auf eine vergleichende Betrachtung der Figuren 1 und 3 im Bereich des Förderriemens 4 verwiesen. Im Ausführungsbeispiel verläuft die Längserstreckung der Führungsbahn 2 in der Horizontalen. In der Figur 3 ist erkennbar, dass die Münzen 1 entlang einer Führungskante 17 laufen.In the Figure 1 one recognizes a partial view of a device for conveying isolated coins 1, with a guide track 2 and with a conveyor belt 4 circulating on a transport arm 3 at a distance d from the guide track 2, the distance d being the distance between a strand 5 of the conveyor belt 4 facing the guide track and is less than the smallest height of an object 1 above the guide track 2. It goes without saying that the distance d is determined when the middle layer is not compressed. The coins 1 can be grasped by the strand 5 of the conveyor belt 4 facing the guide track 2 and can be conveyed on the guide track 2 (in FIG Fig. 1 from right to left) and wherein the static friction and / or sliding friction forces between the objects 1 and the conveyor belt 4 are greater than the static friction and / or sliding friction forces between the objects 1 and the guide track 2. In detail, it becomes clear that the conveyor belt 4 has a layer structure, with at least one support layer 4a, a middle layer 4b and a driving layer 4c, the driving layer 4c facing the guide track 2 and the supporting layer 4a facing the belt rollers 3a of the transport arm 3, and the driving layer 4c and the supporting layer 4a forming outer layers of the conveyor belt 4, and that the middle layer 4b is formed from a material that is more elastically compressible in the direction perpendicular to the guide track 2 than the support layer 4a and the entrainment layer 4c. The latter can be seen in particular in the area of coins 1, where the middle layer 4b is compressed, while the thicknesses of the support layer 4a and the carrying layer 4c are practically unchanged compared to areas without coins 1. In addition to a comparative consideration of the Figures 1 and 3 referenced in the area of the conveyor belt 4. In the exemplary embodiment, the longitudinal extent of the guide track 2 runs in the horizontal. In the Figure 3 it can be seen that the coins 1 run along a guide edge 17.

Der Förderriemen 4 insgesamt ist aus einer Stützschicht 4a auf Basis EDPM oder CR einer Shore A Härte von 80 und einer Dicke von 3,5 mm, einer Mittelschicht 4b auf Basis Moosgummi oder Sylomer-Schaum einer Shore A Härte von 30 und einer Dicke von 2 bis 3,5 mm, sowie einer Mitnahmeschicht 4c auf Basis PU einer Shore A Härte von 80 und einer Dicke von 0,8 mm gebildet.The conveyor belt 4 as a whole consists of a support layer 4a based on EDPM or CR with a Shore A hardness of 80 and a thickness of 3.5 mm, a middle layer 4b based on sponge rubber or Sylomer foam with a Shore A hardness of 30 and a thickness of 2 up to 3.5 mm, as well as a driving layer 4c based on PU with a Shore A hardness of 80 and a thickness of 0.8 mm.

Insbesondere in der Figur 1 ist gut zu erkennen, dass der Förderriemen 4 der Mitnahmeschicht 4c gegenüberliegend eine Antriebsverzahnung 8 aufweist. Aus der Figur 3 wiederum ist ersichtlich, dass der Förderriemen 4 eine endlos umlaufende Stahldrahteinlage 9 aus nebeneinander liegenden Spiralen aufweist.Especially in the Figure 1 it can be clearly seen that the conveyor belt 4 has a drive toothing 8 opposite the driving layer 4c. From the Figure 3 Again it can be seen that the conveyor belt 4 is an endlessly revolving steel wire insert 9 made of adjacent spirals having.

Die Figur 2 in gemeinsamer Betrachtung mit der Figur 3 verdeutlicht, dass der Transportarm 3 mehrere Führungselemente 10 aufweist, welche im Querschnitt zur Längserstreckung des Transportarmes 3 U-förmig sind, wobei der Förderriemen 4 beidseitig seitlich, bezogen auf den Förderriemen 4, durch Stege 11 geführt wird, und wobei der Förderriemen 4 auf einer Stützfläche 12 zwischen den Stegen 11 gleitet. Aus der Figur 2 entnimmt man, dass der Transportarm 3 endständige Umlenkrollen 13, nämlich stirnzahnradförmig, aufweist, wobei die linksseitige Umlenkrolle 13 antreibbar ist.the Figure 2 in joint consideration with the Figure 3 shows that the transport arm 3 has several guide elements 10, which are U-shaped in cross-section to the longitudinal extent of the transport arm 3, the conveyor belt 4 being guided on both sides laterally, based on the conveyor belt 4, by webs 11, and the conveyor belt 4 on one Support surface 12 slides between the webs 11. From the Figure 2 it can be seen that the transport arm 3 has terminal deflecting rollers 13, namely in the form of a spur gear, the deflecting roller 13 on the left-hand side being drivable.

In der Figur 4 ist im Detail dargestellt, dass die Stützfläche 12 eingangsseitig des Transportarms 3 einen keilförmigen Einlaufbereich 14 aufweist. Hier sowie in Figur 2 erkennt man, dass der Transportarm 3 einen Basisträger 15 aufweist, an welchem mehrere Führungselemente 10 orthogonal zur Führungsbahn 2 justierbar, angeordnet sind. Eine vergleichende Betrachtung der Figuren 2 und 4 zeigt, dass die rechte Umlenkrolle 13 in Richtung der Längserstreckung des Transportarmes 3 einstellbar und fixierbar ist. Hierzu ist ein Rollenträger 20 vorgesehen, welcher gegenüber dem Basisträger 15 mittels Langlochführungen verschiebbar und mittels der sich gegen eine basisträgerfeste Stützfläche abstützenden Justierschraube 19 justierbar ist. Die Fixierung erfolgt mittels der Fixierschrauben 18.In the Figure 4 it is shown in detail that the support surface 12 has a wedge-shaped inlet area 14 on the input side of the transport arm 3. Here as well as in Figure 2 it can be seen that the transport arm 3 has a base support 15 on which a plurality of guide elements 10 are arranged so as to be adjustable orthogonally to the guide track 2. A comparative consideration of the Figures 2 and 4th shows that the right deflection roller 13 can be adjusted and fixed in the direction of the longitudinal extension of the transport arm 3. For this purpose, a roller carrier 20 is provided, which can be displaced with respect to the base carrier 15 by means of elongated hole guides and is adjustable by means of the adjusting screw 19 which is supported against a support surface fixed to the base carrier. The fixing takes place by means of the fixing screws 18.

Die in den Figuren dargestellte erfindungsgemäße Vorrichtung ist im Rahmen einer Vorrichtung zum Zählen und/oder Sortieren von Münzen 1 eingesetzt, was aus der in der Figur 3 erkenntlichen Sortieröffnung 21 in der Führungsbahn 2 deutlich wird.The device according to the invention shown in the figures is used in the context of a device for counting and / or sorting coins 1, which is derived from the in Figure 3 recognizable sorting opening 21 in the guide track 2 becomes clear.

Zwischen dem Förderriemen 4 und seiner zwischen den seitlichen Stegen 11 der Führungselemente 10 gelegenen Stützfläche 12 (sofern vorgesehen) findet je nach Materialpaarung Reibung statt. Um diese zu minimieren, sind verschiedene Maßnahmen wie Teflonbeschichtung, Lufteinblasung u.dgl. möglich. Es kann auch ein Zwischenband zwischen dem Förderriemen 4 und der Stützfläche 12 umlaufend geführt werden und zusammen mit dem Förderriemen 4 umlaufen. Auch kann bei einem Förderriemen 4 mit glatter Rückseite, d.h. ohne Verzahnungen 8, eine Rollenführung z.B. aus Nadellagerrollen eingesetzt werden, auf welcher der Förderriemen 4 wie auf einem Förderband geführt wird. Bei einem Förderriemen 4 mit V-förmiger Rückseite können auch zwei seitliche Rollenführungen eingesetzt werden.Between the conveyor belt 4 and its support surface 12 (if provided) located between the lateral webs 11 of the guide elements 10, friction takes place depending on the material pairing. To minimize this, various measures such as Teflon coating, air injection and the like are possible. An intermediate belt can also be circulated between the conveyor belt 4 and the support surface 12 and circulate together with the conveyor belt 4. In the case of a conveyor belt 4 with a smooth back, i.e. without toothing 8, a roller guide, e.g. made of needle roller bearings, can be used on which the conveyor belt 4 is guided like on a conveyor belt. In the case of a conveyor belt 4 with a V-shaped rear, two lateral roller guides can also be used.

Den Figuren 2 und 4 ist entnehmbar, dass Achsen 3b von Riemenrollen 3a positionsfest in dem Transportarm 3 angeordnet sind.The Figures 2 and 4th it can be seen that axles 3b of belt rollers 3a are arranged in a fixed position in the transport arm 3.
