Description

Die Neuerung betrifft eine Vorrichtung zum Umlenken von in einer Ebene transportierten flächigen Materialstücken wie Belegen und dergleichen aus einer ersten Transportrichtung in eine zweite Transportrichtung, umfassend ein mittels einer Antriebsvorrichtung antreibbares Transportrad, das in einem Radlager umeine schräg zur Transportebene gerichtete Radachse drehbar gelagert ist, wobei das Radlager seinerseits um eine senkrecht zur Transportebene gerichtete und mindestens annähernd durch den Berührungsbereich des Transportrades mit der Transportebene verlaufende Schwenkachse zwischen einer ersten und einer zweiten Stellung verstellbar ist,in denen die Radachse senkrecht zur ersten bzw. zweiten Transportrichtung gerichtet ist, sowie ein mit dem Transportrad zum Vorschub der Materialstücke zusammenwirkendes Gegenelement.The innovation relates to a device for deflecting flat material pieces, such as covers and the like, which are transported in one plane from a first transport direction into a second transport direction, comprising a transport wheel which can be driven by a drive device and which is rotatably mounted in a wheel bearing about a wheel axis directed obliquely to the transport plane, whereby the wheel bearing in turn is adjustable between a first and a second position, in which the wheel axis is directed perpendicular to the first or second transport direction, and one with which is directed about a pivot axis directed perpendicular to the transport plane and at least approximately through the area of contact of the transport wheel with the transport plane Transport wheel for feeding the pieces of material interacting counter element.

Eine derartige Vorrichtung arbeitet inder Weise, daß ein zwischen das Gegenelement und das Transportrad eingeführter Beleg von dem Transportrad durch Reibschluß vorgeschoben wird, bis der Beleg durch ein Anschlag angehalten wird. Aufgrund des dadurch erzeugten Gegenmomentes an dem Transportrad wird dieses um die Schwenkachse des Radlagers in seine zweite Stellung verschwenkt, in der es den Beleg entlang des Anschlages in der zweiten Transportrichtung vorschieben kann. Diese Vorrichtungen dienen einerseits zum Umlenken von Belegen und andererseits zum Ausrichten derselben, indem der Beleg zunächst gegen einen ersten Anschlag und dann in der zweiten Transportrichtung gegen einen zweiten Anschlag geschoben wird. Es wird im weiteren meist von Belegen gesprochen, da die eingangs genannten Vorrichtungenvor allem für die Umlenkung von Belegen verwendet werden. Es versteht sich jedoch, daß die genannte Vorrichtung auch zum Umlenken anderer Materialstücke geeignet ist.Such a device works in such a way that a document inserted between the counter element and the transport wheel is pushed by the transport wheel by friction until the document is stopped by a stop. Due to the counter torque generated by this on the transport wheel, it is pivoted about the pivot axis of the wheel bearing into its second position, in which it can advance the document along the stop in the second transport direction. These devices serve on the one hand to deflect documents and on the other hand to align them by first pushing the document against a first stop and then against a second stop in the second transport direction. It will go on mostly spoken of receipts, since the devices mentioned above are mainly used for the redirection of receipts. However, it is understood that the device mentioned is also suitable for deflecting other pieces of material.

Bei einer bekannten Vorrichtung der oben genannten Art ist das Gegenelement von einer in einer Kugelbuchse frei drehbar gelagerten Kugel gebildet, die ständig mit dem Transportrad in Berührung steht. Die Kugel läuft beim Antrieb des Transportrades somit ständig mit, auch wenn kein Beleg transportiert wird. Die Erfahrung hat gezeigt, daß auch bereits ein geringer Abrieb aufgrund der pausenlosen Bewegung der Kugel oder in die Kugelbuchse fallender Papierstaub die Kugel bremst, so daß diese leicht zum Stillstand kommt. Ohne einen Beleg zwischen dem Transportrad und der Kugel führt dies dazu, daß das Transportrad in seine zweite Stellung verschwenkt wird und somit nicht bereit für das Einführen eines neuen Beleges ist. Auch bei der Verwendung von Blattfedern oder Rollen als Gegenelemente ist diese Art von Fehlfunktion aufgetreten.In a known device of the type mentioned above, the counter element is formed by a ball which is freely rotatably mounted in a ball bushing and which is in constant contact with the transport wheel. The ball runs with the drive of the transport wheel constantly, even if no document is transported. Experience has shown that even slight abrasion due to the non-stop movement of the ball or paper dust falling into the ball bushing brakes the ball so that it easily comes to a standstill. Without a document between the transport wheel and the ball, this leads to the transport wheel being pivoted into its second position and thus not ready for the insertion of a new document. This type of malfunction has also occurred when using leaf springs or rollers as counter elements.

Der Neuerung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs aenannten Art so auszubilden, daß das Gegenelement praktisch wartungsfrei ist und ein Verschwenken des Transportrades in seine zweite Stellung ohne das Vorhandensein eines Beleges ausgeschlossen ist.The innovation is based on the task of designing a device of the type mentioned at the outset in such a way that the counter-element is practically maintenance-free and pivoting of the transport wheel into its second position is ruled out without the presence of a document.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß das Geqenelement von einem in der Transportebene angeordneten starren Körpergebildet ist, der eine im wesentlichen konzentrisch zur Schwenkachse des Radlagers angeordnete und zum Transportrad hin offene Aussparung aufweist, deren Rand einen gegenüber dem Transportrad kleineren Durchmesser und einen annähernd der Dicke des zu transportierendenMaterialstückes entsprechenden Abstand von der Umfangsfläche des Transportrades besitzt.This object is achieved according to the innovation in that the Geqenelement is formed by a rigid body arranged in the transport plane, which has a recess arranged essentially concentrically to the pivot axis of the wheel bearing and open to the transport wheel, the Edge has a smaller diameter than the transport wheel and a distance from the peripheral surface of the transport wheel which corresponds approximately to the thickness of the piece of material to be transported.

Bei der neuerungsgemäßen Lösung berühren sich also das Gegenelement und das Transportrad nicht. Damit wird der Verschleiß des Gegenelementes auf den Abrieb beschränkt, der durch die über den starren Körper geschobenen Materialstücke hervorgerufen wird. Der für den Transport erforderliche Reibschluß zwischen dem Materialstück und dem Transportrad wird dadurch erzeugt, daß das Transportrad aufgrund der gewählten Abmessungen leicht in die Aussparung des starren Körpers eintaucht und dabei das Materialstück geringfügig verformt, so daß dieses aufgrund der durch die Verformung hervorgerufenen Rückstellkraft an das Transportrad angedrückt wird. Wenn das Materialstück aus dem Spalt zwischen dem Gegenelement und dem Transportrad herausgelaufen ist, erfolgt üblicherweise eine Rückstellung des Transportrades durch eine Feder in seine erste Stellung. Ein Auslenken aus dieser Stellung ohne ein Materialstück ist aufgrund der fehlenden Berührung zwischen dem Gegenelement und dem Transportrad nicht möglich. Somit befindet sich das Transportrad stets in der für das Einführen eines weiteren Materialstückes geeigneten Stellung.In the solution according to the innovation, the counter element and the transport wheel do not touch. The wear of the counter element is thus limited to the abrasion caused by the pieces of material pushed over the rigid body. The frictional connection required for the transport between the material piece and the transport wheel is generated in that the transport wheel easily dips into the recess of the rigid body due to the selected dimensions and thereby slightly deforms the material piece, so that this due to the restoring force caused by the deformation to the Transport wheel is pressed. When the piece of material has run out of the gap between the counter element and the transport wheel, the transport wheel is usually reset to its first position by a spring. A deflection from this position without a piece of material is not possible due to the lack of contact between the counter element and the transport wheel. The transport wheel is thus always in the position suitable for the insertion of a further piece of material.

Vorzugsweise ist der starren Körper in Form einer Scheibe oder eines Tellers ausgebildet, der in Richtung der Schwenkachse des Radlagers relativ zum Transportrad verstellbar sein kann, so daß der Abstand zwischen dem starren Körper und dem Transportrad auf die unterschiedliche Dicke verschiedener Belege oder Materialstücke einstellbar ist. Vorzugsweise ist der starren Körper in Richtung auf seine dem Transportrad nächstgelegene Stellung durch Federmittel vorgespannt, so daß eine selbsttätige Anpassung des gegenseitigen Abstandes von Gegenelement und Transportrad auf die jeweilige Belegdicke erfolgt. Eine einfache Lösung für diese federnde Lagerung des starren Körpers erhält man beispielsweise dadurch, daß der scheibenförmige oder tellerförmige starren Körper an einer Blattfeder befestigt ist.The rigid body is preferably designed in the form of a disk or a plate which can be adjustable in the direction of the pivot axis of the wheel bearing relative to the transport wheel, so that the distance between the rigid body and the transport wheel can be adjusted to the different thicknesses of various documents or pieces of material. Preferably the rigid body is towards it the position closest to the transport wheel is prestressed by spring means, so that the mutual distance between the counter element and the transport wheel is automatically adjusted to the respective document thickness. A simple solution for this resilient mounting of the rigid body is obtained, for example, in that the disk-shaped or plate-shaped rigid body is attached to a leaf spring.

Um Abrieb und Papierstaub leichter aus dem Bereich der Umlenkvorrichtung entfernen zu können, ist vorzugsweise in dem starren Körper im Zentrum der Aussparung eine Durchbrechung ausgebildet, durch die der Abrieb und der Papierstaub hindurchfallen können.In order to be able to remove abrasion and paper dust more easily from the region of the deflection device, an opening is preferably formed in the rigid body in the center of the recess, through which the abrasion and the paper dust can fall.

Um keine zu scharfen Kanten an dem Gegenelement zu erhalten, die die Erzeugung von Papierstaub fördern und selbst einem erhöhten Verschleiß ausgesetzt sind, ist das Gegenelement vorzugsweise so ausgebildet, daß sich an den Rand der Aussparung eine sich radial nach innen von dem Transportrad entfernende Randfläche anschließt. Diese Randfläche kann konisch ausgebildet oder auch konvex gekrümmt sein.In order not to obtain too sharp edges on the counter element, which promote the production of paper dust and are themselves exposed to increased wear, the counter element is preferably designed in such a way that an edge surface, which extends radially inward from the transport wheel, adjoins the edge of the recess . This edge surface can be conical or can also be convexly curved.

Bei einer bevorzugten Ausführungsform der Neuerung ist der Rand der Aussparung von einem sich über die Transportebene erhebenden Ringwulst gebildet, der zu einer stärkeren Verformung des zwischen dem Transportrad und dem Gegenelement hindurchlaufenden Beleges und damit auch zu einer den Reibschluß zwischen dem Beleg und dem Transportrad erhöhenden größeren Rückstellkraft führt. Der Ringwulst kann einen annhähernd kreishalbförmigen, dreieckigen oder auch trapezförmigen Querschnitt aufweisen.In a preferred embodiment of the innovation, the edge of the recess is formed by an annular bead which rises above the transport plane and which leads to a greater deformation of the document passing between the transport wheel and the counter element and thus also to a larger larger one which increases the frictional connection between the document and the transport wheel Restoring force. The ring bead can have an approximately circular half-shaped, triangular or even trapezoidal cross-section.

Der starren Körper kann in Richtung der Transportebene verstellbar angeordnet sein , um so die Aussparung bezüglich der Schwenkachse des Radlagers zentrieren zu können.The rigid body can ver in the direction of the transport plane be arranged adjustable so as to be able to center the recess with respect to the pivot axis of the wheel bearing.

In den Figuren 1 und 2 erkennt man ein Einführungsblech 10 auf dem ein flächiges Materialstück, beispielsweise ein Papierblatt, eine Karte oder ein Beleg 12. aufgelegt und gegen einen Anschlag 14 geschoben werden soll. Hierzu dient ein Transportrad 16 im Zusammenwirken mit einem Gegenelement oder einem Umlenkteller 18 , der in noch zu beschreibenderweise an dem Einführungsblech 10 gehalten ist.FIGS. 1 and 2 show an insertion plate 10 on which a flat piece of material, for example a paper sheet, a card or a document 12, is to be placed and pushed against a stop 14. For this purpose, a transport wheel 16 is used in cooperation with a counter element or a deflection plate 18, which is held on the insertion plate 10 in a manner to be described.

Das Transportrad 16 ist in einem Radlager 20 um eine Achse 22 frei drehbar gelagert, die schräg zu der die Transportebene für den Beleg 12 bildenden Oberfläche 24 des Einführungsbleches 10 gerichtet ist. Das Radlager 20 ist auf einer Welle 26 um eine Achse 28 schwenkbar gelagert, die senkrecht zur Oberfläche 24 des Einführungsbleches durch den Berührungsbereich zwischen dem Transportrad 16 und der Transportebene des Beleges 12 verläuft.The transport wheel 16 is mounted in a wheel bearing 20 so as to be freely rotatable about an axis 22 which is directed obliquely to the surface 24 of the insertion plate 10 which forms the transport plane for the document 12. The wheel bearing 20 is pivotally mounted on a shaft 26 about an axis 28 which runs perpendicular to the surface 24 of the insertion plate through the contact area between the transport wheel 16 and the transport plane of the document 12.

Die Welle 24 ist mittels Lager 30 und 32 in zwei zueinander parallelen Platten .34 bzw. 36 gehalten, die durch zwei Distanzbolzen 38 in einem vorgegebenen Abstand fest miteinander verbunden sind. Auf der Welle 26 ist ferner eine Riemenscheibe 40 gelagert, die mit einer Antriebsscheibe 42 drehfest verbunden ist und über einen nicht dargestellten Riemenantrieb von einem Motor her angetrieben werden kann. Die Antriebsscheibe 42 ihrerseits liegt an dem Umfang des Transportrades 16 an, um dieses ständig anzutreiben.The shaft 24 is held by means of bearings 30 and 32 in two mutually parallel plates .34 and 36, which are firmly connected to one another at a predetermined distance by two spacer bolts 38. On the shaft 26, a pulley 40 is also mounted, which is rotatably connected to a drive pulley 42 and can be driven by a motor via a belt drive, not shown. The drive disk 42 in turn lies against the circumference of the transport wheel 16 in order to drive it continuously.

Das Radlager 20 ist starr mit einem Arm 44 verbunden, der parallel zu der Transportebene gerichtet ist. An dem Arm 44 greift eine Zugfeder 46 an, deren anderes Ende an einem mit der Platte 34' fest verbundenen Zapfen 48 eingehängt ist. Mit dieser Zugfeder 46 wird der Arm 44. gegen einen mit der Platte 34 verbundenen ersten Anschlag 50. gespannt. In der dadurch vorgegebenen Stellung des Radlagers 20 nimmt das Transportrad 16 die in der Fig. 1 dargestellte erste Stellung ein, in welcher die Radachse 22 senkrecht zu der durch den Pfeil A in Fig. 1 angegebenen ersten Transportrichtung gerichtet ist und in der das Transportrad 16 den Beleg 12 in der ersten Transportrichtung A gegen den Anschlag 14 schiebt, wobei es sich in Richtung des Pfeiles B dreht. Wird der Beleg 12 durch den Anschlag 14 an einer weiteren Bewegung gehindert, so wird durch die Drehung des Transportrades 16: auf das Radlager 20 bezüglich der Achse 28 ein Drehmoment ausgeübt, so daß sich das Radlager 20 zusammen mit dem Transportrad 16 in Richtuna des Pfeiles C um die Achse 28 drehten, bis der Arm 44 an einem mit der Platte 34 verbundenen zweiten Anschlag 52 anschlägt (siehe Fig. 2). In dem in den Figuren 1 und 2 dargestellten Ausführungsbeispiel durchläuft dabei das Radlager 20 einen Schwenkwinkel von 90°. In der in Fig. 2 dargestellten Stellung schiebt das Transportrad 16 nun den Beleg 12: in Blickrichtung an dem Anschlag 14 entlang. Sowie der Beleg .12 den Eingriffsbereich mit dem Transportrad 16 verlassen hat, kehrt dieses unter der Wirkung der gespannten Zugfeder 46 in seine in Fig. 1 dargestellte erste Stellung oder Ausgangsstellung zurück.The wheel bearing 20 is rigidly connected to an arm 44 which is directed parallel to the transport plane. A tension spring 46 acts on the arm 44, the other end of which is suspended on a pin 48 which is fixedly connected to the plate 34 '. With this tension spring 46, the arm 44 is tensioned against a first stop 50 connected to the plate 34. 1, in which the wheel axis 22 is directed perpendicular to the first transport direction indicated by arrow A in FIG. 1 and in which the transport wheel 16 pushes the document 12 in the first transport direction A against the stop 14, whereby it turns in the direction of arrow B. If the document 12 is prevented from further movement by the stop 14, a torque is exerted on the wheel bearing 20 with respect to the axis 28 by the rotation of the transport wheel 16, so that the wheel bearing 20 together with the transport wheel 16 move in the direction of the arrow Rotate C about axis 28 until arm 44 abuts a second stop 52 connected to plate 34 (see FIG. 2). In the embodiment shown in Figures 1 and 2, the wheel bearing 20 passes through a pivot angle of 90 °. In the position shown in FIG. 2, the transport wheel 16 now pushes the document 12: along the stop 14 in the viewing direction. As soon as the document .12 has left the engagement area with the transport wheel 16, this returns under the action of the tensioned tension spring 46 to its first position or starting position shown in FIG. 1.

Im weiteren soll nun genauer auf die Ausbildung des Gegenelementes 18 eingegangen werden, das beim Transport der Belege 12 mit dem Transportrad 16 zusammenwirkt. Gemäß Fig. 4 besteht das Gegenelement 18 im wesentlichen aus einer Scheibe oder einem Teller 54 mit einem verdickten Mittelabschnitt 56 . Dieser weist bei dem Ausführungsbeispiel gemäß Fig. 4 an seiner Oberseite eine Aussparung 58 auf, die von einem Ringwulst 60 umgeben ist. Die Flanken des Ringwulstes 60 sind von einer Innenkonusfläche '62 bzw. einer Außenkonusfläche 64 gebildet, die sich in einer den Rand der Aussparung 58 bildenden ringförmigen Kante 66 schneiden.Furthermore, the design of the counter element 18, which interacts with the transport wheel 16 during the transport of the receipts 12, will now be discussed in more detail. 4, the counter element 18 essentially consists of a disk or a plate 54 with a thickened central section 56. In the exemplary embodiment according to FIG. 4, this has a recess 58 on its upper side, which is surrounded by an annular bead 60. The flanks of the annular bead 60 are formed by an inner conical surface 62 and an outer conical surface 64 which intersect in an annular edge 66 forming the edge of the recess 58.

Der Mittelabschnitt 56 ist nach unten hin durch einen Stutzen 68 verlängert und weist eine koaxial zur Tellerachse 70 angeordnete Bohrung 72 auf, die mit der Aussparung 58 durch eine Durchbrechung 74 verbunden ist.The middle section 56 is extended downwards by a connecting piece 68 and has a bore 72 which is arranged coaxially to the plate axis 70 and which is aligned with the off saving 58 is connected by an opening 74.

Mit dem Stutzen 68 ist der Teller 54 in eine Bohrung 76 (Fig. 3) in einer Blattfeder .78 eingesetzt, die mit Hilfe von Stellschrauben 80 an einer Trägerplatte 82 befestigt ist. Diese ist ihrerseits mittels zwei Exzenterschrauben 84 an der Unterseite des Einführungsbleches 10 so befestigt, daß der Teller 54 mit dem Ringwulst 60_ durch eine Durchbrechung 86 (Fig. 2) in dem Einführungsblech 10 hindurchragt. Mit Hilfe einer Stiftschlitzführung, die einen an der Unterseite des Einführungsbleches 10 befestigten Stift 88 und einen in der Trägerplatte 82 ausgebildeten Schlitz 90 umfaßt, sowie der Exzenterschrauben 84 kann die Trägerplatte 82 relativ zum Einführungsblech 10 so justiert werden, daß die Tellerachse 70 im wesentlichen mit der Schwenkachse 28- des Radlagers 20 zusammenfällt. Mit Hilfe der Stellschrauben 80 kann die Blattfeder 78 relativ zum Transportrad 16 so eingestellt werden, daß ein geringer Spalt 92 zwischen der Umfangsfläche des Transportrades 16 und dem die Aussparung 58 umgebenden Rand 66 an dem Teller 54 verbleibt, solange sich kein Beleg 12 in der Vorrichtung befindet. Gemäß Fig. 4 ragt das Transportrad 18 zwar geringfügig in die Aussparung 58. des Tellers 54. hinein, jedoch berührt das Transportrad 16 das Gegenelement .18 nicht. Wird ein Beleg 12. zwischen das Transportrad 16 und das Gegenelement 18 eingeführt, so wird der Beleg 12 durch das Transportrad leicht in die Aussparung 58 hineingedrückt. Die dabei auftretende Verformung des Beleges erzeugt durch die Steifigkeit des Belegmaterials eine gewisse Rückstellkraft, durch die der Beleg gegen die Umfangsfläche des Transportrades 16 gedrückt wird, so daß ein sicherer Reibschluß zwischen dem Transportrad 16 und dem Beleg erzeugt wird. Je nach der Dicke des Beleges weicht das Gegenelement 18 aufgrund seiner federnden Lagerung nach unten aus, so daß gleichzeitig dünne und dickere Belege verarbeitet werden können. Dabei kann die Breite des Spaltes 92 jeder Zeit durch die Einstellschrauben 80 verändert werden.With the nozzle 68, the plate 54 is inserted into a bore 76 (FIG. 3) in a leaf spring 78, which is fastened to a carrier plate 82 with the aid of set screws 80. This in turn is fastened by means of two eccentric screws 84 to the underside of the insertion plate 10 in such a way that the plate 54 with the annular bead 60_ projects through an opening 86 (FIG. 2) in the insertion plate 10. Using a Stiftschlitzführun g, which comprises a secured to the underside of the insertion plate 10 pin 88 and a formed in the support plate 82 slot 90, and the eccentric bolts 84, the support plate 82 to be adjusted relative to the entry plate 10 so that the cup axis 70 is substantially with the pivot axis 28 - of the wheel bearing 20 coincides. With the aid of the set screws 80, the leaf spring 78 can be adjusted relative to the transport wheel 16 so that a small gap 92 remains between the peripheral surface of the transport wheel 16 and the edge 66 surrounding the recess 58 on the plate 54, as long as there is no document 12 in the device located. 4, the transport wheel 18 projects slightly into the cutout 58 of the plate 54, but the transport wheel 16 does not touch the counter element .18. If a document 12 is inserted between the transport wheel 16 and the counter element 18, the document 12 is slightly pressed into the recess 58 by the transport wheel. The resulting deformation of the document creates a certain restoring force due to the rigidity of the document material, by which the document is pressed against the peripheral surface of the transport wheel 16, so that a secure frictional connection between the transport wheel 16 and the document is generated. Depending on the Thickness of the document evades the counter element 18 due to its resilient mounting downwards, so that thin and thicker documents can be processed at the same time. The width of the gap 92 can be changed at any time by the adjusting screws 80.

Die Fig. 5A bis 5E zeigen verschiedene Querschnittsformen des Ringwulstes 60. Besonders bevorzugt ist dabei die auch in der Fig. 4 dargestellte Lösung mit einer Außenkonusfläche und einer Innenkonusfläche, da sie einerseits das Einschieben des Beleges in den Spalt 92 erleichtet, ohne daß der Beleg mit seiner Vorderkante an dem Ringwulst 60 hängen bleiben kann, und andererseits verhindert, daß der Beleg beim Eindrücken in die Aussparung 58 geknickt wird.5A to 5E show different cross-sectional shapes of the annular bead 60. Particularly preferred is the solution also shown in FIG. 4 with an outer cone surface and an inner cone surface, since on the one hand it facilitates the insertion of the document into the gap 92 without the document with its leading edge can get caught on the annular bead 60, and on the other hand prevents the document from being bent when pressed into the recess 58.

Der wesentliche Vorteil der neuerungsgemäßen Lösung besteht darin, daß das Transportrad 16 das Gegenelement 18 niemals direkt berührt. Dadurch wird zum einen der Verschleiß des Transportrades und des Gegenelementes erheblich reduziert und zum anderen sicher gestellt, daß das Transportrad 16 ohne einen Beleg niemals in seine zweite Stellung verschwenkt werden kann und damit stets für die Aufnahme eines Beleges bereit ist. Anfallender Papierstaub und Abrieb kann durch die Durchbrechung 74 aus der Aussparung 58 abgeführt werden, so daß die Transport- und Umlenkzone zwischen dem Transportrad 16 und dem Gegenelement 18 nicht durch angehäuften Papierstaub verschmutzt oder gar blockiert werden kann.The main advantage of the solution according to the innovation is that the transport wheel 16 never touches the counter element 18 directly. As a result, on the one hand the wear of the transport wheel and the counter element is considerably reduced and on the other hand it is ensured that the transport wheel 16 can never be pivoted into its second position without a receipt and is therefore always ready to receive a receipt. Accruing paper dust and abrasion can be removed through the opening 74 from the recess 58, so that the transport and deflection zone between the transport wheel 16 and the counter element 18 cannot be contaminated or even blocked by accumulated paper dust.
