Abstract

The invention addresses the problem of removing the bottom card (3) from a stack of cards (2) disposed in a shaft (1), without producing significant friction between the surfaces of the cards. This problem, which particularly affects plastic cards designed to carry printed data, is solved by the invention by virtue of the fact that the front (4) and rear (5) edges of the bottom card (3) lie between two transfer elements (6, 7) which are driven to rotate about parallel axes (12, 13). The bottom card (3) is first displaced backwards (8) by a short distance and simultaneously separated from the card immediately above it, whereupon the front edge (4) of the card is released and is free to move downwards. The bottom card (3) is then transferred in the opposite direction (9) and falls freely at an angle on to a conveyor.

Vorrichtung zum Vereinzeln von Karten aus einemDevice for separating cards from one
KartenstapelDeck of cards
Die Erfindung bezieht sich auf eine Vorrichtung zum Entnehmen der jeweils untersten Karte eines in einem Schacht geführten Kartenstapels, z.B. einer als Datenträger dienenden Plastikkarte.The invention relates to a device for removing the bottom card of a stack of cards guided in a slot, e.g. a plastic card serving as a data carrier.
Es ist bekannt, die jeweils unterste Karte eines Kartenstapels mit Hilfe eines Förderbandes abzuziehen, gegen welches die unterste Karte durch das Gewicht des Kartenstapels angedrückt wird. Diese Maßnahme hat den Nachteil, daß eine ganzflächige Reibung der abzuziehenden Karte entlang der nachfolgenden Karte stattfindet. Wenn die Karten bedruckt oder mit sonstigen Farbschichten versehen sind, besteht die Gefahr des Abriebes des Farbbelages und daher der Verschmierung des Druckes. Diese Problematik tritt besonders beim Handling von Plastikkarten auf, die als Datenträger gestaltet sind.It is known to pull off the bottom card of a stack of cards with the aid of a conveyor belt against which the bottom card is pressed by the weight of the stack of cards. This measure has the disadvantage that there is friction over the entire surface of the card to be removed along the subsequent card. If the cards are printed or provided with other layers of color, there is a risk of the ink covering rubbing off and therefore smearing the print. This problem occurs especially when handling plastic cards that are designed as data carriers.
Der Erfindung liegt die Aufgabe zugrunde, eine Vereinzelungsvorrichtung zu entwickeln, welche den Kartenabzug vom Stapel unter Vermeidung großflächiger Reibungen ermöglicht und das Biegen oder sonstige Verformen der Karten beim Vereinzeln vermeidet.The invention is based on the object of developing a separating device which enables the card to be withdrawn from the stack while avoiding large-area friction and avoids bending or other deformation of the cards during separation.
Diese Aufgabe wird im Sinne der Erfindung dadurch gelöst, daß in der Ebene der untersten Karte zwei auf gegenüberliegende Kartenränder einwirkende Abschiebeorgane angeordnet sind, von denen das erste Abschiebeorgan eine kurze seitliche Bewegung der untersten Karte in ihrer Ebene in der einen Richtung und das zweite Abschiebeorgan eine Abschiebebewegung der Karte in der entgegengesetztenThis object is achieved in the sense of the invention in that in the plane of the bottom card two pushing elements acting on opposite card edges are arranged, of which the first pushing element a short lateral movement of the bottom card in its plane in one direction and the second pushing element one Pushing the card in the opposite direction
ERSATZBLÄΪT (REGEL 26) Richtung erzeugt, wobei die Karte vom ersten Abschiebeorgan für den freien Fall auf einen Förderer freigegeben wird.SPARE BLADE (RULE 26) Direction generated, the card is released by the first pusher for free fall on a conveyor.
Bei dieser Methode findet eine Reibung nur während der ersten kurzen Abschiebebewegung der Karte statt, wobei zugleich eine Distanzierung der untersten Karte von der nächstfolgenden stattfindet, bis der vordere Kartenrand vom ersten Abschiebeorgan freigegeben worden ist. Von diesem Zeitpunkt an, findet nur noch eine geringfügige Reibung im Bereiche des rückwärtigen Kartenrandes statt, während nämlich das zweite Abschiebeorgan gegen diesen rückwärtigen Kartenrand stößt und die im übrigen Bereich bereits freiliegende Karte in Richtung zum darunter befindlichen Förderer abschiebt.With this method, friction only occurs during the first short push-off movement of the card, with the bottom card being distanced from the next card at the same time until the front card edge has been released by the first push-off device. From this point in time, there is only a slight friction in the area of the rear edge of the card, while the second push-off element pushes against this rear edge of the card and pushes the card already exposed in the remaining area towards the conveyor below.
In den Unteransprüchen 1 bis 7 sind spezielle Merkmale der Erfindung aufgeführt. Im Anspruch 2 wird das erste Abschiebeorgan als drehbar angetriebener Rotationskörper gekennzeichnet, der in seinem Umfang eine ebene Auflagefläche für den vorderen Rand der untersten Karte aufweist. Demzufolge befindet sich dieses Abschiebeorgan unterhalb des vorderen Stapelrandes. Diese ebene Auflagefläche entspricht in ihrer radialen Ausdehnung etwa der Dicke einer Karte. Sie wird von einer Stufe begrenzt, welche ihrerseits als Abschiebeelement wirkt und gegen den vorderen Kartenrand auftrifft. Es genügt eine 1/4-Umdrehung des ersten Abschiebeorganes, um den vorderen Kartenrand für den dann folgenden freien Fall freizugeben. Während dieser 1/4-Umdrehung wird die unterste Karte während der kurzen Rückwärtsbewegung von der nächstfolgenden Karte gelöst, so daß die Reibung auf ein Minimum beschränkt ist.In the subclaims 1 to 7 special features of the invention are listed. In claim 2, the first push-off member is characterized as a rotatably driven rotating body which has a flat support surface for the front edge of the bottom card in its circumference. As a result, this pusher is located below the front edge of the stack. The radial extension of this flat contact surface corresponds approximately to the thickness of a card. It is limited by a step, which in turn acts as a push-off element and hits the front edge of the card. A 1/4 turn of the first push-off element is sufficient to release the front edge of the card for the free fall that follows. During this 1/4 turn, the bottom card is released from the next card during the short backward movement, so that the friction is kept to a minimum.
ERSAΓZBLÄΓT(REGEL26) Der Anspruch 3 befaßt sich mit der Ausbildung des zweiten Abschiebeorganes. Dieses ist als Schwinge so ausgebildet, daß es während der ersten rückwärtigen Abschiebebewegung dem hinteren Kartenrand ausweicht, bis das vordere Kartenende freigekommen ist, um daraufhin in entgegengesetzter Drehbewegung gegen den hinteren Kartenrand zu treffen und die unterste Karte endgültig abzuschieben.ERSAΓZBLÄΓT (REGEL26) The claim 3 deals with the formation of the second deportation member. This is designed as a rocker so that it dodges the rear edge of the card during the first backward pushing movement until the front end of the card is released, in order then to hit the rear edge of the card in the opposite direction of rotation and to finally push off the bottom card.
Beide Abschiebeorgane sind um zueinander parallele Achsen drehbar und bilden zusammen ein Kurbelgetriebe, wie dies in den Ansprüchen 4 und 5 definiert ist.Both pushers are rotatable about mutually parallel axes and together form a crank mechanism as defined in claims 4 and 5.
Mit den Merkmalen des Anspruches 6 wird erreicht, daß das rückwärtige Kartenende beim ersten kurzen Abschiebevorgang leicht eingeklemmt wird, so daß die Karte beim Freigeben durch das vordere Abschiebeorgan nicht willkürlich herunterfallen kann. Man braucht lediglich den rückwärtigen Kartenrandbereich in einen passenden Spalt der Schachtwandung einzuschieben, in den außerdem eine oder mehrere Kugeln federnd hineinragen. Diese Kugeln werden durch den Kartenrand gegen Federwirkung niedergedrückt. Die Federwirkung reicht aus, um die gewünschte Klemmung der' Karte zu erreichen, bis das zweite Abschiebeorgan gegen den hinteren Kartenrand treffen kann.With the features of claim 6 it is achieved that the rear end of the card is slightly pinched during the first short push-off operation, so that the card cannot fall down arbitrarily when released by the front push-off member. You only need to insert the rear edge of the card into a suitable gap in the shaft wall, into which one or more balls also protrude. These balls are pressed against the spring action by the card edge. The spring action is sufficient to achieve the desired clamping of the card until the second push-off element can hit the rear edge of the card.
In den Ansprüchen 8 bis 11 sind Erfindungsmerkmale aufgeführt, welche das schonende Beschicken des Schachtes mit Kartenstapeln beschreiben, wobei außerdem eine große Leistung erzielt werden soll. Diese Anordnung nach den Ansprüchen 8 bis 10 stellt sich als eine vorteilhafte Weitergestaltung der Erfindungslehre nach den Ansprüchen 1 bis 7 dar. Es ist aber darauf hinzuweisen, daß die Beschickung eines Schachtes zum Vereinzeln der Karten nicht unbedingt voraussetzt, daß die VereinzelungsvorrichtungIn the claims 8 to 11 features of the invention are listed, which describe the careful loading of the shaft with stacks of cards, in addition, a great performance is to be achieved. This arrangement according to claims 8 to 10 presents itself as an advantageous further development of the inventive concept according to claims 1 to 7. It should be pointed out, however, that the loading of a slot for separating the cards does not necessarily require that the separating device
ERSÄΓZBLAΓT (REGEL 26) nach den Ansprüchen 1 bis 7 ausgebildet ist. Deshalb hat der Anspruch 8 selbständige Erfindungsbedeutung, weil die darin offenbarte Anordnung eines Drehtellers mit Füllschächten auch bei anderen Vereinzelungsvorrichtungen mit Erfolg eingesetzt werden kann.ERSÄΓZBLAΓT (RULE 26) is formed according to claims 1 to 7. Therefore, claim 8 has independent meaning of the invention, because the arrangement disclosed therein of a turntable with filling shafts can also be used successfully in other separating devices.

ERSÄΓZBLÄΓΓ(REGEL26) Im Ausführungsbeispiel der Fig. 1 ist mit (1) ein Schacht symbolisch dargestellt, zwischen dessen Schachtwänden (26) sich ein Kartenstapel (2) befindet, dessen jeweils unterste Karte (3) abgezogen und vereinzelt werden soll.ERSÄΓZBLÄΓΓ (RULE 26) In the exemplary embodiment in FIG. 1, a shaft is symbolically represented by (1), between the shaft walls (26) of which there is a stack of cards (2), the bottom card (3) of which is to be removed and separated.
Der Kartenstapel (2) ruht am vorderen Kartenrand (4) auf einer ebenen Auflagefläche (10) eines ersten Abschiebeorganes (6) und am hinteren Kartenrand (5) auf einer leistenförmigen Auflage (17).The stack of cards (2) rests on the front edge of the card (4) on a flat support surface (10) of a first push-off element (6) and on the rear edge (5) on a strip-shaped support (17).
In gleicher Ebene wie die unterste Karte (3) erstreckt sich im Bereiche des hinteren Kartenrandes (5) ein Spalt (18), dessen lichte Weite so bemessen ist, daß die unterste Karte (3) in den Spalt (18) eingeschoben werden kann. Mindestens eine, vorzugsweise zwei federnd abgestützte Kugeln (19) greifen in den Spalt (18) ein. Die Federkraft ist so eingestellt, daß beim Einschieben der untersten Karte (3) in den Spalt (18) die Kugeln weggedrückt werden, wobei aber die Federkraft so groß ist, daß der hintere Kartenrandbereich (5) von den Kugeln (19) nach dem Einschieben in den Spalt (18) festgeklemmt wird.In the same plane as the bottom card (3), a gap (18) extends in the area of the rear edge of the card (5), the clear width of which is dimensioned such that the bottom card (3) can be inserted into the gap (18). At least one, preferably two resiliently supported balls (19) engage in the gap (18). The spring force is set so that the balls are pushed away when the bottom card (3) is inserted into the gap (18), but the spring force is so great that the rear edge area (5) of the balls (19) after insertion is clamped in the gap (18).
Das erste Abschiebeorgan (6) ist um die Achse (12) in Pfeilrichtung drehbar angetrieben. Dadurch trifft das stufenartige Ende der ebenen Auflagefläche (10) gegen den vorderen Kartenrand (4) und verursacht ein Verschieben der unteren Karte (3) in Richtung des Pfeiles (8) (siehe Fig. 2), wobei das hintere Kartenende (5) in den Spalt (18) eintaucht.The first push-off element (6) is driven so that it can rotate about the axis (12) in the direction of the arrow. As a result, the step-like end of the flat support surface (10) hits against the front edge of the card (4) and causes the lower card (3) to be displaced in the direction of the arrow (8) (see FIG. 2), the rear end of the card (5) in dips the gap (18).
Über eine Koppel (14) wird vom ersten Abschiebeorgan (6) das zweite Abschiebeorgan (7) betätigt, das als Schwinge ausgebildet und um die Achse (13) hin und her drehbar ist. Beide Achsen (12,13) sind zueinander parallel gerichtet. Die Koppel (14) ist über Gelenke (15,16) mit den beidenVia a coupling (14), the first push-off element (6) actuates the second push-off element (7), which is designed as a rocker and can be rotated back and forth about the axis (13). Both axes (12, 13) are directed parallel to each other. The coupling (14) is connected to the two via joints (15, 16)
ERSATZBLÄTT (REGEL 26) Abschiebeorganen (6,7) verbunden. Dadurch entsteht eine Viergelenkkette bzw. Kurbelgetriebe, bei dem das erste Abschiebeorgan (6) als antreibendes Element im Sinne einer Kurbel dient.SPARE BLADE (RULE 26) Push-off elements (6,7) connected. This creates a four-link chain or crank mechanism in which the first push-off element (6) serves as a driving element in the sense of a crank.
Selbstverständlich ist es auch möglich, dem ersten Abschiebeorgan (6) eine oszillierende Drehbewegung um die Achse (12) zu vermitteln, beispielsweise um einen Winkel von ± 180° .Of course, it is also possible to impart an oscillating rotary movement about the axis (12) to the first push-off element (6), for example by an angle of ± 180 °.
Die Koppel (14) ist in ihrer Anlenkung so festgelegt, daß ihre Abschiebenase (11) dem hinteren Kartenrand (5) ausweicht, während die untere Karte (3) durch das erste Abschiebeorgan (6) in die Position gemäß Fig. 2 gebracht wird. Die Karte (3) ist fast durchgehend von der nächstfolgenden Karte des Kartenstapels (2) gelöst und nur der hintere Kartenrand (5) ist im Spalt (18) durch die Kugeln (19) festgeklemmt. Wenn das erste Abschiebeorgan (6) eine 1/4-Bewegung durchgeführt hat, kann sich der vordere Kartenrand (4) von der Auflagefläche (10) des ersten Abschiebeorganes (6) lösen und nach unten sich bewegen.The coupling (14) is fixed in its articulation in such a way that its push-off nose (11) dodges the rear edge of the card (5), while the lower card (3) is brought into the position according to FIG. 2 by the first push-off element (6). The card (3) is detached almost continuously from the next card in the stack of cards (2) and only the rear edge of the card (5) is clamped in the gap (18) by the balls (19). When the first push-off element (6) has carried out a 1/4 movement, the front edge of the card (4) can detach from the support surface (10) of the first push-off element (6) and move downward.
Bei diesem ersten Bewegungsabschnitt tritt keine Biegung oder sonstige Verformung der Karte ein. Auch löst sich die untere Karte (3) praktisch sofort von der nächstliegenden Karte, so daß fast keine Reibungsbeanspruchung der Kartenoberfläche eintritt.During this first movement section, there is no bending or other deformation of the card. The lower card (3) also comes off almost immediately from the nearest card, so that there is almost no frictional stress on the card surface.
Wenn das erste Abschiebeorgan (6) sich von der Position gemäß Fig. 2 in diejenige der Fig. 3 bewegt, erfolgt eine Umkehr der Bewegung der Koppel (14) in Richtung des Pfeiles (9). Dabei trifft die Abschiebenase (11) des zweiten Abschiebeorganes (7) gegen den hinteren Kartenrand (5) und schiebt diesen aus dem Spalt (18) heraus. In dieser in Fig. 3 gezeigten Stellung kann die untere Karte (3) frei abfallen, wobei sie durch die Drehbewegung der Abschiebenase (11) einen Bewegungsimpuls in Richtung des Pfeiles (9) erhält. Die Karte (3) kann nun auf einen nicht gezeigten Förderer unterhalb des Kartenstapels (2) kontrolliert fallen, welcher die Karte zu einer nachfolgenden Arbeitsstellung bringt.When the first push-off element (6) moves from the position according to FIG. 2 to that of FIG. 3, the movement of the coupling (14) is reversed in the direction of the arrow (9). The push-off nose (11) of the second push-off element (7) hits the rear edge of the card (5) and pushes it out of the gap (18). In this position shown in Fig. 3, the lower card (3) can be free drop, receiving a movement impulse in the direction of the arrow (9) due to the rotary movement of the push-off nose (11). The card (3) can now fall in a controlled manner onto a conveyor (not shown) below the card stack (2), which brings the card to a subsequent working position.
Diese beschriebene Anordnung ist vor allem zum Vereinzeln von Plastikkarten geeignet, welche als Datenträger dienen. Die bei solchen Datenträgern üblichen Prägungen und Aufdrucke werden durch den erfindungsgemäßen Kartenabzug weitgehend geschont, weil Flächenreibungen und Verformungen vermieden werden. Die erfindungsgemäße Vereinzelungsvorrichtung kann aber auch bei beliebigen anderen Karten zum Einsatz kommen, wenn diese eine genügende Steifigkeit besitzen, um die Abschiebebewegung durch das erste Abschiebeorgan (6) ausführen zu können.This arrangement described is particularly suitable for separating plastic cards that serve as data carriers. The embossments and imprints customary in such data carriers are largely spared by the card deduction according to the invention because surface friction and deformation are avoided. The separating device according to the invention can, however, also be used with any other cards if they have sufficient rigidity to be able to carry out the push-off movement by the first push-off member (6).
Die Leistung der erfindungsgemäßen Vereinzelungsvorrichtung ist außerordentlich hoch, weshalb in den Fig. 4 und 5 eine Vorrichtung dargestellt ist, die das schnelle Nachfüllen des Schachtes mit Kartenstapeln (2) ermöglicht. Danach sind auf einem Drehteller (20) mehrere Füllschächte (21) angeordnet, welche von oben her von Hand mit Kartenstapeln (2) beschickt werden können. In der Ruhelage des Drehtellers (20) befindet sich unter einem der Füllschächte (21) der Schacht (1) gemäß Fig. 1 bis 3. Es soll beim Stillstand des Drehtellers (20) dann der Kartenstapel in den darunter befindlichen Schacht (l) abgesenkt werden können, ohne daß Einzelkarten sich lösen und schrägstellen können. Zu diesem Zweck ist entsprechend den Fig. 6 bis 8 im erfindungsgemäßen Schacht (1) eine aus zwei Stützen (23) bestehende Anordnung vorgesehen, welche in der Stellung gemäß Fig. 6 mit dem oberen Schachtrand (22) fluchtet und den ankommenden Kartenstapel (2) aufnimmt. Die Stützen (23) sind um die Achsen (25) in einander entgegengesetzten Richtungen drehbar. Sie weisen zylinderförmige Auflageflächen (24) auf, die sich beim Absenken der Stützen (23) an der unteren Karte abwälzen und daher ebenfalls schonend auf die Karten (2) einwirken. In der Stellung gemäß Fig. 8 hat der Kartenstapel (2) seine untere Auflagestellung gemäß Fig. 1 erhalten. Die Stützen (23) sind mit ihren Auflageflächen (24) durch entsprechende Aussparungen in den Schachtwänden (26) nach außen geführt worden, so daß sie die Vereinzelung der Karten nicht behindern können.The performance of the separating device according to the invention is extremely high, which is why a device is shown in FIGS. 4 and 5 which enables the slot to be refilled quickly with card stacks (2). Thereafter, several filling shafts (21) are arranged on a turntable (20), which can be loaded with card stacks (2) from above by hand. In the rest position of the turntable (20), the slot (1) according to FIGS. 1 to 3 is located under one of the filling shafts (21). When the turntable (20) is at a standstill, the stack of cards is then lowered into the slot (1) below can be without single cards can come loose and tilt. For this purpose, according to FIGS. 6 to 8, an arrangement consisting of two supports (23) is provided in the slot (1) according to the invention, which in the position according to FIG. 6 is aligned with the upper edge of the slot (22) and the incoming card stack (2nd ) records. The supports (23) are rotatable in opposite directions about the axes (25). They have cylindrical contact surfaces (24) which roll on the lower card when the supports (23) are lowered and therefore also act gently on the cards (2). In the position according to FIG. 8, the card stack (2) has received its lower support position according to FIG. 1. The supports (23) with their support surfaces (24) have been guided outwards through corresponding cutouts in the shaft walls (26), so that they cannot hinder the separation of the cards.
Dieser beschriebene erste Füllvorgang des Schachtes (1) setzt voraus, daß sich im Schacht (1) keine Karten (3) befinden. Beim Nachfüllen eines Schachtes (1), in dem sich noch Karten (3) befinden, bleiben die Stützen (23) in der wirkungslosen Stellung gemäß Fig. 8.This described first filling process of the shaft (1) presupposes that there are no cards (3) in the shaft (1). When refilling a shaft (1) in which there are still cards (3), the supports (23) remain in the ineffective position according to FIG. 8.
Statt dessen wird mit nicht dargestellten Rückhaltefingern gearbeitet, welche die Füllschächte (21) des Drehtellers (20) unten abschließen. Innerhalb des Schachtes (1), praktischerweise einige mm unterhalb des oberen Schachtrandes (22) befindet sich eine ebenfalls nicht dargestellte Lichtschranke. Diese meldet, wenn sie von der jeweils obersten Karte (3) eines Kartenstapels (2) passiert wird, wodurch eine Drehbewegung des Drehtellers (20) in Gang gesetzt wird, welche einen nächsten Kartenstapel (2) deckungsgleich über den Schacht (1) bringt. Nun werden die Rückhaltefinger zurückgezogen, worauf der Kartenstapel (2) auf die im Schacht (1) befindlichen Karten (3) abfallen kann.Instead, work is carried out with retaining fingers, not shown, which close the filling shafts (21) of the turntable (20) at the bottom. Inside the shaft (1), conveniently a few mm below the upper edge of the shaft (22), there is a light barrier, also not shown. This signals when it is passed by the uppermost card (3) of a stack of cards (2), which starts a rotary movement of the turntable (20), which congruently brings a next stack of cards (2) over the slot (1). Now the retaining fingers are withdrawn, whereupon the stack of cards (2) can fall onto the cards (3) located in the slot (1).
