Abstract

In spaced relationship from an infeed track or path for an imbricated product formation there is arranged an outfeed track or path. Between the infeed and outfeed tracks there is provided a group of movable track elements which are spaced in overlying or superimposed relationship from one another in their direction of movement. This group of track elements is guided and moved transversely with respect to the infeed and outfeed tracks or paths. Conveyor means serve to transfer the printed products from the infeed track in each case by means of one of the track elements to the outfeed track. In this way it is possible, without releasing the printed products out of the imbricated product formation and without altering the movement of the imbricated product formation or interrupting such movement, to render accessible each of the printed products for performing further processing operations thereat during the throughpass thereof at the relevant track element.

Description

Die Erfindung betrifft eine Einrichtung zum Auflockern einer Schuppenformation von Druckprodukten quer zu deren Fläche.The invention relates to a device for loosening a scale formation of printed products across their surface.

Die eine Druckpresse verlassenden Druckprodukte fallen meistens in einer Schuppenformation, d.h. in einer solchen Formation an, in der der vordere Bereich eines Druckproduktes auf dem hinteren Bereich des vorangehenden Druckproduktes unmittelbar aufliegt. Eine solche Schuppenformation ist auch eine der zweckmässigsten Formationen, um die anfallenden Druckprodukte mittels entsprechender Fördereinrichtungen kontinuierlich zu transportieren.The printed products leaving a printing press mostly fall in a scale formation, i.e. in such a formation in which the front region of a printed product lies directly on the rear region of the preceding printed product. Such a scale formation is also one of the most convenient formations for continuously transporting the resulting printed products by means of appropriate conveying devices.

Wenn an den in Schuppenformation anfallenden Druckprodukten noch weitere, maschinelle Operationen durchzuführen sind, dann mussten bisher die Druckprodukte aus der Schuppenformation herausgelöst werden, was entweder vorerst durch Stapelung und anschliessende Vereinzelung des Stapels erreicht wurde, oder aber dadurch, dass die von der Fördereinrichtung anfallende Schuppenformation so weit beschleunigt wurde, dass aufeinanderfolgende Druckprodukte sich nicht mehr überlappen, sondern durch Lücken getrennt sind. In beiden Fällen ging die ursprüngliche Schuppenformation verloren. Dies hatte auch zur Folge, dass nach den exemplarweise durchgeführten, weiteren Operationen in der Regel die für die Beförderung zweckmässige Schuppenformation wieder hergestellt werden musste.If further mechanical operations have to be carried out on the printed products resulting in scale formation, then previously the printed products had to be detached from the scale formation, which was either achieved initially by stacking and subsequent separation of the stack, or else by the fact that the scale formation resulting from the conveyor device has been accelerated to such an extent that successive printed products no longer overlap but are separated by gaps. In both cases, the original lost scale formation. This also had the consequence that after the additional operations carried out as an example, the scale formation suitable for the transport had to be restored.

Die erfindungsgemässe Einrichtung geht hier - wie schon die Gegenstandsbezeichnung sagt - völlig neue Wege. Hier wird die Schuppenformation zwar auch aufgelockert aber quer zu den Flächen der Druckprodukte. Dadurch werden die Druckprodukte ebenfalls individuell zugänglich, aber die Schuppenformation bleibt im wesentlichen erhalten. Dementsprechend ist die vorgeschlagene Einrichtung gemäss der Erfindung dadurch gekennzeichnet, dass eine Zuführbahn und im Abstand davon eine Wegführbahn vorgesehen sind, und dass zwischen diesen Bahnen eine quer zu denselben geführte und bewegte Schar von in deren Bewegungsrichtung in Abständen voneinander sich überdeckender Bahnelemente angeordnet ist, wobei Fördermittel vorgesehen sind, um die Druckprodukte von der Zuführbahn je über eines der Bahnelemente auf die Wegführbahn zu überführen.The device according to the invention - as the object name already says - goes completely new ways. Here the scale formation is loosened up but across the surface of the printed products. This also makes the printed products individually accessible, but the scale formation is essentially preserved. Accordingly, the proposed device according to the invention is characterized in that a feed path and at a distance from it an exit path are provided, and between these paths a coulter that is guided and moved transversely to the same is arranged, with path elements that overlap in the direction of their movement, at intervals Funding means are provided in order to transfer the printed products from the feed path via one of the path elements to the path leading away.

The invention is described below purely for example with reference to the drawing. It shows:
  • 1 is a perspective and very schematic representation of the essential elements of a device,
  • 2a-2d snapshots of a printed product during its passage on a web element, the preceding and the following Print products on the one hand and the adjacent web elements on the other hand are not shown for the sake of simplicity,

  • Fig. 4 in a similar representation as Fig. 1 shows another embodiment.

Die in Fig. 1 dargestellte Einrichtung 10 besitzt eine Zuführbahn 11 und eine im Abstand davon angeordnete Wegführbahn 12. Sowohl die Zuführbahn 11 als auch die Wegführbahn 12 weisen je einen Gleittisch 13 bzw. 14 auf, wobei die beiden Gleittische 13, 14 in diesem Beispiel etwa auf gleicher Höhe angeordnet sind. Entlang der dem Betrachter abgekehrten Ränder der Gleittische 13, 14 ist ein in Richtung des Pfeiles 15 angetriebener Endlosförderer 16 vorhanden, der mit in regelmässigen Abständen voneinander an einem Zugorgan 18 befestigten Mitnehmern 17 bestückt ist. Jeder der Mitnehmer 17 greift an der nachlaufenden Kante jeweils eines Druckproduktes Z an, wobei die Druckprodukte in einer Schuppenformation S anfallen. Der Antrieb des Endlosförderers erfolgt über einen nur gestrichelt angedeuteten Motor 19 und ein von diesem angetriebenes, am Zugorgan 18 angreifendes Antriebsrad 20. Die Zuführbahn 11 umfasst somit in diesem Beispiel den Gleittisch 13 und einen entsprechenden Abschnitt des Endlosförderers 16. Aehnliches gilt sinngemäss für die Wegführbahn 12.The device 10 shown in FIG. 1 has a feed path 11 and a path 12 arranged at a distance therefrom. Both the feed path 11 and the path 12 each have a slide table 13 or 14, the two slide tables 13, 14 in this example are arranged approximately at the same height. Along the edges of the sliding tables 13, 14 facing away from the viewer there is an endless conveyor 16 which is driven in the direction of the arrow 15 and which is equipped with drivers 17 fastened to one another at regular intervals on a pulling element 18. Each of the drivers 17 engages on the trailing edge of a printed product Z, the printed products occurring in a scale formation S. The endless conveyor is driven by a motor 19, which is only indicated by dashed lines, and a drive wheel 20 which is driven by the motor and engages on the traction element 18. In this example, the feed path 11 thus comprises the sliding table 13 and a corresponding section of the endless conveyor 16. The same applies analogously to the path of travel 12th

Zwischen der Zuführbahn 11 und der Wegführbahn 12 ist eine Schar 21 im wesentlichen rechteckiger, ebener und in Abständen übereinander angeordneter Bahnelemente 22 vorhanden. Jedes der Bahnelemente 22 hat etwa dieselbe Breite wie die Gleittische 13, 14 und ist an seiner dem Betrachter zugekehrten Kante fest an zwei endlos umlaufenden, kettenartigen Zugorganen 23, 24 verankert, wobei die Bewegungsrichtung der Zugorgane 23, 24 und damit der Schar 21 im Bereich zwischen der Zuführbahn 11 und der Wegführbahn 12 mit Pfeilen 25 angegeben ist. Der Antrieb der Zugorgane 23, 24 erfolgt über einen nur für das Zugorgan 24 mit gestrichelter Linie angedeuteten Motor 26, dessen Antriebsgeschwindigkeit - wie sich noch zeigen wird - auf jene des Motors 19 abgestimmt ist, was mit der gestrichelten Linie angedeutet sein soll.Between the feed path 11 and the path 12 is a sheet 21 of essentially rectangular, flat and spaced-apart path elements 22 available. Each of the track elements 22 has approximately the same width as the sliding tables 13, 14 and is firmly anchored at its edge facing the viewer to two endless, chain-like traction elements 23, 24, the direction of movement of the traction elements 23, 24 and thus the blade 21 in the area between the feed path 11 and the path 12 is indicated by arrows 25. The traction elements 23, 24 are driven by a motor 26 indicated only by the broken line for the traction element 24, the drive speed of which, as will be shown, is matched to that of the motor 19, which is to be indicated by the broken line.

Jedes der Bahnelemente 22 reicht im Prinzip vom Ende des Gleittisches 13 bis zum Anfang des Gleittisches 14, überbrückt somit den dazwischen vorhandenen Abstand. Die Fläche jedes der Bahnelemente 22 ist bezüglich der Bahn des Endlosförderers 16 im Bereich der Schar 21 in dessen Förderrichtung (Pfeil 15) gesehen ansteigend angeordnet. Die Bewegungsgeschwindigkeit der Schar 21 ist derart auf die Fördergeschwindigkeit des Endlosförderers 16 abgestimmt, dass jeweils jedes der Bahnelemente 22 die Bahn des Endlosförderers 16 auf der Höhe eines Mitnehmers 17 kreuzt.In principle, each of the track elements 22 extends from the end of the sliding table 13 to the beginning of the sliding table 14, thus bridging the distance between them. The surface of each of the track elements 22 is arranged to rise with respect to the track of the endless conveyor 16 in the area of the coulter 21 in its direction of conveyance (arrow 15). The speed of movement of the coulter 21 is matched to the conveying speed of the endless conveyor 16 such that each of the track elements 22 crosses the track of the endless conveyor 16 at the level of a driver 17.

Wie aus Fig. 1 deutlich hervorgeht, wird die Schuppenformation S beim Durchlauf durch die Schar 21 quer zur Fläche der einzelnen Druckprodukte Z in dem Sinne aufgelockert, dass der vorlaufende Bereich jedes der Druckprodukte Z beim Auflaufen auf eines der Bahnelemente 22 wegen dessen geneigter Anordnung vom vorangehenden Druckprodukt abgehoben wird, ohne dass in Förderrichtung gesehen der Abstand zwischen zwei aufeinanderfolgenden Druckprodukten (gegeben durch den Abstand der Mitnehmer 17) wesentlich verändert würde. Die Schuppenformation S bleibt also auch im Bereich der Schar 21 erhalten und dennoch ist im Bereich dieser Schar jedes einzelne der Druckprodukte individuell zugänglich. Man kann also beim Beispiel gemäss Fig. 1 während des Durchlaufes der Schuppenformation S durch die Schar 21 beispielsweise auf jedes der auf einem der Bahnelemente 22 liegenden und vorgeschobenen Druckprodukte Z von der Betrachterseite her ein oder mehrere weitere Druckprodukte (nicht dargestellt) auflegen, etwa im Sinn eines Zusammenführens eines Hauptproduktes mit einem oder mehreren Vorprodukten.As is clear from Fig. 1, the scale formation S is loosened when passing through the sheet 21 transversely to the surface of the individual printed products Z in the sense that the leading region of each of the printed products Z when it hits one of the web elements 22 due to its inclined arrangement from preceding printed product is lifted without the distance between two successive printed products seen in the conveying direction (given by the distance of the drivers 17) would change significantly. The scale formation S is therefore also retained in the area of the sheet 21, and yet each individual print product is individually accessible in the area of this sheet. In the example according to FIG. 1, one or more other printed products (not shown) (not shown) can be placed on the viewer side, for example, on each of the printed products Z lying and advanced on one of the web elements 22 during the passage of the scale formation S through the sheet 21 The sense of merging a main product with one or more intermediate products.

Anhand der Fig. 2a bis 2d sei die soeben geschilderte Wirkungsweise der Einrichtung nochmals verdeutlicht.The operation of the device just described is illustrated once again with reference to FIGS. 2a to 2d.

Man erkennt in Fig. 2a ein soeben vom Ende des Gleittisches 13 vollständig auf eines der Bahnelemente 22 aufgelaufenes Druckprodukt Z, das durch den entsprechenden Mitnehmer 17 auf das dargestellte Bahnelement aufgeschoben worden ist. Während sich der Mitnehmer 17 im Sinne des Pfeiles 15 weiter bewegt, senkt sich das Bahnelement 22 im Sinne des Pfeiles 25, wobei die Geschwindigkeit des Endlosförderers 16 so auf die Sinkgeschwindigkeit des Bahnelementes 22 abgestimmt ist, dass der dem Betrachter abgekehrte Rand des dargestellten Bahnelementes 22 die Bahn des Endlosförderers 16 zwischen Zuführbahn 13 und Wegführbahn 14 stets auf der Höhe des dargestellten Mitnehmers 17 kreuzt. Dadurch bleibt der Mitnehmer 17 im Eingriff mit der nachlaufenden Kante des Druckproduktes, das seinerseits weiter entlang des Bahnelementes 22 geschoben wird, wie aus Fig. 2b und 2c ersichtlich ist. Gegen Ende des Durchlaufes des Druckproduktes Z auf dem Bahnelement 22 (Fig. 2d) hat sich letzteres soweit nach unten bewegt, dass dessen, dem Gleittisch 14 zugekehrte Kante etwa die Höhe des Anfangs dieses Gleittisches erreicht hat. Dabei wird das Druckprodukt Z vornüber wieder in Horizontallage kippen, und mit seinem vorlaufenden Bereich wieder unmittelbar auf den nachlaufenden Bereich des zuvor vom vorangehenden Bahnelement auf die Wegführbahn geförderten Druckproduktes zu liegen kommen.FIG. 2a shows a printed product Z that has just run from the end of the sliding table 13 onto one of the web elements 22 and has been pushed onto the illustrated web element by the corresponding driver 17. While the driver 17 moves further in the direction of arrow 15, the web element 22 lowers in the direction of arrow 25, the speed of the endless conveyor 16 being matched to the sinking speed of the web element 22 such that the edge of the illustrated web element 22 facing away from the viewer the path of the endless conveyor 16 between the feed path 13 and the path 14 always crosses at the level of the driver 17 shown. As a result, the driver 17 remains in engagement with the trailing edge of the printed product, which in turn is pushed further along the web element 22, as can be seen from FIGS. 2b and 2c. Towards the end of the passage of the printed product Z on the web element 22 (FIG. 2d), the latter has moved down so far that its, the Slide table 14 facing edge has approximately reached the height of the start of this slide table. In this case, the printed product Z will tip over again in the horizontal position, and its leading region will again lie directly on the trailing region of the printed product previously conveyed from the preceding path element to the path of travel.

Die Fig. 3 zeigt wiederum in sehr schematisierter Darstellung eine Ausführungsvariante. Man erkennt den in Richtung des Pfeiles 15 laufenden Endlosförderer 16 mit seinen in Förderrichtung in regelmässigen Abständen angeordneten Mitnehmern 17. Zu erkennen ist auch die praktisch gleich wie bei der Ausführungsform der Fig. 1 ausgebildete Wegführbahn 12 mit dem vom Endlosförderer 16 flankierten Gleittisch 14. Schliesslich ist auch die ähnlich wie in Fig. 1 im Sinne der Pfeile 25 sich bewegende Schar 21 der Bahnelemente 22 zu erkennen, die einzeln an den umlaufenden Zugorganen 23, 24 befestigt sind.3 again shows an embodiment variant in a very schematic representation. One recognizes the endless conveyor 16 running in the direction of the arrow 15 with its drivers 17 arranged at regular intervals in the conveying direction. The guideway 12 with the sliding table 14 flanked by the endless conveyor 16 flanked practically the same as in the embodiment of FIG. 1 can also be seen. Finally can also be seen the group 21 of the track elements 22 which moves in the direction of the arrows 25 in a manner similar to that in FIG. 1 and which is individually fastened to the circumferential tension members 23, 24.

Der wesentliche Unterschied zur Fig. 1 bildet die Zuführbahn 11. Diese ist gebildet durch ein endloses Förderband 28, dessen Förderrichtung (Pfeil 29) etwa rechtwinklig zum Verlauf des Endlosförderers 16 gerichtet ist und dessen Förderebene praktisch parallel zu der Fläche der Bahnelemente 22 ist. Das Ende des Förderbandes 28 ist gegenüber den vorbeilaufenden, dem Betrachter zugekehrten Kanten der Bahnelemente 22 unmittelbar benachbart angeordnet.The essential difference from FIG. 1 is the feed path 11. This is formed by an endless conveyor belt 28, the conveying direction (arrow 29) of which is approximately at right angles to the course of the endless conveyor 16 and the conveying plane is practically parallel to the surface of the track elements 22. The end of the conveyor belt 28 is arranged directly adjacent to the passing edges of the web elements 22 facing the viewer.

Wie aus Fig. 3 deutlich ersichtlich, wird die auf der Zuführbahn angelieferte Schuppenformation S beim Uebergang auf die Bahnelemente 22 der Schar 21 nicht nur in dem Sinne aufgelockert, dass die einzelnen Produkte Z voneinander angehoben werden, sondern auch winklig (ohne Drehung der einzelnen Produkte Z) umgelenkt wird, denn die einzelnen Produkte Z gelangen erst dann mit den Mitnehmern 17 in Eingriff, wenn sie das Ende des Förderbandes 28 verlassen haben und über die ganze Breite eines der Bahnelemente 22 hinaus geschoben worden sind. Die Schuppenformation S bleibt im Bereich der Schar 21 erhalten. Zum Ausrichten der im Bereich der Schar 21 entstehenden und hier durch die Mitnehmer 17 des Endlosförderers 16 transportierten Schuppenformation kann auf der dem Betrachter abgekehrten Seite ein Führungs- oder Anschlagblech 30 vorgesehen sein.As can be clearly seen from FIG. 3, the scale formation S delivered on the feed path is loosened not only in the sense that the individual products Z are raised from each other, but also deflected at an angle (without rotation of the individual products Z), because the individual products Z only come into engagement with the drivers 17 when they have left the end of the conveyor belt 28 and over the entire width of one of the track elements 22 have been pushed out. The scale formation S remains in the area of the sheet 21. A guide or stop plate 30 can be provided on the side facing away from the viewer in order to align the scale formation which arises in the area of the coulter 21 and is transported here by the drivers 17 of the endless conveyor 16.

Bei der Ausführungsform der Fig. 3 wird sehr wohl ein Teil der Länge der Bahnelemente 22 durch die Zuführbahn 11 beansprucht, so dass die Druckprodukte nicht über die gesamte Länge der Bahnelemente 22 individuell zugänglich sind. Da aber der Länge der Bahnelemente 22 keine prinzipiellen, sondern höchstens durch praktische Ueberlegungen bestimmte Grenzen gesetzt sind, kommt dieser Umstand lediglich scheinbar einem Nachteil gleich. Vielmehr hat die Ausführungsform der Fig. 3 folgenden Vorteil, der sich aus der winkligen Umlenkung der angelieferten Schuppenformation S ergibt. Wenn die aus der Druckpresse anfallenden Druckprodukte Z gefalzt sind, so bildet, wie in Fig. 3 auf dem Förderband 28 dargestellt, deren Hauptfalz z' die vorlaufende Kante. Nach der winkligen Umlenkung bilden diese Hauptfalze z' aller Druckprodukte den dem Betrachter abgekehrten Rand der in der Schar 21 entstehenden und weiter transportierten Schuppenformation. Damit ist die dem Hauptfalz z' gegenüberliegende Kante jedes der Druckprodukte (die sogenannte "Blume") im Bereich der Schar 21 von der Betrachterseite her zugänglich, so dass in Fig. 3 beispielsweise durch nicht dargestellte Mittel Beilagen in die gefalteten Druckprodukte geschoben oder auf diese aufgelegt werden können.In the embodiment of FIG. 3, part of the length of the web elements 22 is very much claimed by the feed web 11, so that the printed products are not individually accessible over the entire length of the web elements 22. However, since the length of the track elements 22 is not limited in principle, but at most determined by practical considerations, this fact only appears to be a disadvantage. Rather, the embodiment of FIG. 3 has the following advantage, which results from the angular deflection of the delivered scale formation S. When the printed products Z resulting from the printing press have been folded, their main fold z 'forms the leading edge, as shown in FIG. 3 on the conveyor belt 28. After the angular deflection, these main folds z 'of all printed products form the edge facing away from the viewer of the scale formation formed in the sheet 21 and transported further. Thus, the edge of each of the printed products (the so-called "flower") opposite the main fold z 'is accessible from the viewer side in the area of the sheet 21, so that in FIG. 3, for example, inserts into the folded printed products can be pushed or placed on them.

Das Ausführungsbeispiel der Fig. 4 ist im wesentlichen gleich aufgebaut wie jenes der Fig. l. Diese ist insbesondere für die Beschickung mit gefalteten Druckprodukten Z geeignet, die mit seitlich liegendem Hauptfalz z' in der Schuppenformation S sind. Der wesentliche Unterschied besteht in einer unterschiedlichen "Phasenlage" der inbezug aufeinander synchronen Bewegungen des Endlosförderers 16 und der Schar 21. Unter Berücksichtigung des in Richtung 15 gemessenen Masses der Druckprodukte Z sind die Geschwindigkeiten des Endlosförderers 16 einerseits und der Schar 21 andererseits so aufeinander abgestimmt, dass jeweils die dem Gleittisch 13 zugekehrte Seite eines Bahnelementes 22 im Moment, da die vorlaufende Kante eines Druckproduktes die Endkante des Gleittisches 13 erreicht, noch nicht ganz die Höhe dieser Endkante erreicht hat, sondern noch um etwa die Hälfte der Dicke eines Druckproduktes höher liegt. In diesem Falle wirkt die dem Gleittisch 13 zugekehrte Kante jedes der Bahnelemente 22 auf das jeweils eintreffende Druckprodukt wie ein Oeffnungsschwert in dem Sinne, dass nur die obere Hälfte des Druckproduktes Z auf das betreffende Bahnelement 22 zu liegen kommt, während die untere Hälfte desselben Druckproduktes auf das vorangegangene Bahnelement bzw. auf die obere Hälfte des entlang diesem Bahnelement vorgeschobenen Druckproduktes aufliegt. Dadurch werden die Druckprodukte beim Durchlauf durch die Schar 21 geöffnet und der dabei entstehende Oeffnungsspalt bietet sich dar, um von der Betrachterseite her beispeilsweise eine Beilage in (und nicht auf) das Druckprodukt einzuschieben.The embodiment of FIG. 4 is constructed essentially the same as that of FIG. 1. This is particularly suitable for loading with folded printed products Z which are in the scale formation S with the main fold z 'lying on the side. The main difference lies in a different "phase position" of the movements of the endless conveyor 16 and the coulter 21 which are synchronous with respect to one another. Taking into account the dimension of the printed products Z measured in the direction 15, the speeds of the endless conveyor 16 on the one hand and the coulter 21 on the other hand are coordinated with one another, that the side of a web element 22 facing the sliding table 13 has not yet fully reached the height of this end edge at the moment, since the leading edge of a printed product reaches the end edge of the sliding table 13, but is still about half the thickness of a printed product. In this case, the edge of each of the web elements 22 facing the sliding table 13 acts like an opening sword on the respectively arriving printed product in the sense that only the upper half of the printed product Z comes to rest on the relevant web element 22, while the lower half of the same printed product the preceding web element or on the upper half of the printed product fed along this web element. As a result, the printed products are opened as they pass through the sheet 21, and the opening gap which arises in this way presents itself, for example, to insert an insert into (and not onto) the printed product from the viewer's side.

Selbstverständlich kann auch die Ausführungsform der Fig. 4 ohne die beschriebene unterschiedliche "Phasenlage" der Bewegungen des Endlosförderers 16 und der Schar 21 auch mit einer Schuppenformation betrieben werden, in der gefaltete Druckprodukte mit seitlich liegendem Hauptfalz z' sind. Dann kommt jedoch das ganze Druckprodukt auf jeweils ein Bahnelement 22 zu liegen.Of course, the embodiment of the Fig. 4 without the described different "phase position" of the movements of the endless conveyor 16 and the coulter 21 can also be operated with a scale formation in which folded printed products with a lateral main fold z '. Then, however, the entire printed product comes to rest on one web element 22 in each case.

Die Zuführ- und Wegführbahn 11 bzw. 12 brauchen nicht auf derselben Höhe zu liegen. Beispielsweise kann die Wegführbahn 12 tiefer als die Zuführbahn 11 angeordnet sein. In diesem Falle hat zum Beispiel die Bahn des Endlosförderers 16 im Bereich der Schar 21 den Höhenunterschied zwischen Zuführ- und Wegführbahn 11 bzw. 12 zu überwinden. Das kann beispielsweise durch entsprechende Umlenkung des Zugorganes 18 oder durch Unterteilung des Endlosförderers in einen Zuführabschnitt, in einen "Schar"-Abschnitt und in einen Wegführabschnitt geschehen. In diesem Falle können die Flächen der Bahnelemente 22 auch im wesentlichen parallel zu den Gleittischen 13, 14 sein. Auch dann bleibt die Fläche der Bahnelemente auf die nun im Bereich der Schar 21 sinkende Bahn des Förderers 16 in dessen Bewegungsrichtung gesehen ansteigend.The feed and path 11 and 12 do not need to be at the same height. For example, the path 12 can be arranged lower than the feed path 11. In this case, for example, the path of the endless conveyor 16 in the area of the coulter 21 has to overcome the height difference between the feed path and the path 11 or 12. This can be done, for example, by appropriately deflecting the traction element 18 or by dividing the endless conveyor into a feed section, into a "coulter" section and into a removal section. In this case, the surfaces of the track elements 22 can also be essentially parallel to the sliding tables 13, 14. Even then, the surface of the track elements on the track of the conveyor 16, which is now sinking in the area of the coulter 21, remains increasing in its direction of movement.

Auch können die Bahnelemente an umlaufend angetriebenen, kreisförmigen Reifen angeordnet sein, und sich von diesen radial nach innen oder nach aussen erstrecken. Sofern in einer solchen Ausführung ein Endlosförderer entlang der nun strahlenförmigen Schar der Bahnelemente führt, ist dessen Bahn auf die der Befestigungsstelle der Bahnelemente an den kreisförmigen Reifen abgekehrte Seite der Bahnelemente zu verlegen. Ausserdem sind in diesem Falle die Flächen der Bahnelemente zweckmässig nicht eben sondern verwunden auszubilden.The track elements can also be arranged on circumferentially driven, circular tires and extend radially inwards or outwards therefrom. If, in such an embodiment, an endless conveyor runs along the now radial array of web elements, its web is to be laid on the side of the web elements facing away from the fastening point of the web elements on the circular tires. In addition, in this case the surfaces of the web elements are expediently not to be formed flat but twisted.

In einer weitern Ausführungsvariante ist es möglich, jedes der Bahnelemente selbst förderwirksam zu gestalten, zum Beispiel selbst als Förderband auszubilden oder mit einem solchen zu versehen. Dieses Förderband wäre dann zweckmässig nur dann anzutreiben, wenn sich das Bahnelement im Bereich zwischen Zuführ- und Wegführbahn befindet.In a further embodiment variant, it is possible to design each of the track elements itself to be effective in terms of conveying, for example to design them as a conveyor belt or to provide them with one. This conveyor belt would then only be expedient if the path element is located in the area between the feed and exit path.
