Definitions

  • the present invention relates to a device for winding up a continuously occurring stream of flakes of flexible sheet-like structures, in particular of folded printed products, to form a roll according to the preamble of patent claim 1.
  • Comparable devices are known for example from DE-GM 6 608 411 and from DE-PS 2 544 135. With these previously known devices, however, sacks, pouches and similar flat workpieces and non-folded printed products, for example newspapers, resulting in scale formation are wound into so-called "scale tape rolls". This determination is due to the fact that the workpieces wound with the previously known devices are practically incompressible, while folded printed products represent compressible structures to a certain degree.
  • the means for frictionally driving the winding in the area of its circumference are formed by a driven roller on which the winding rests by its own weight, the winding being free is rotatably supported at one end of a swing arm.
  • the drive forces that can be transmitted with this winding drive are comparatively low, because the transmission takes place theoretically only at the common surface line between the surface of the roller and that of the winding.
  • this drive would not be suitable for printing product winding because the inevitable slippage entails the risk of the ink smearing on the flat side of the printing product.
  • a further disadvantage of this device is that the height of the finished winding or its winding core depends on the outside diameter of the finished winding, since, as already mentioned, the winding is held freely rotatably at one end of a swing arm while the outside diameter of the finished winding depends on the number and thickness of the products present in the winding. Therefore, to remove a finished roll, which can have a very considerable weight, either ground-based lifting means, which can be adjusted to different heights of the winding core, or overhead hoists are required in this known device. Such overhead hoists can at best only transport the finished rolls to one place in the same hall in which the device is installed, but not through door openings, so that the rolls must be reloaded.
  • the last-mentioned disadvantages are at least partially eliminated in the device according to DE-PS 2 544 135 insofar as the winding core and thus also the winding is held freely rotatably in fixed bearing blocks.
  • the winding drive is carried out by two driven pressure belts which partially wrap around the winding.
  • the disadvantage of this device is that the guidance of the drive belts requires considerable technical effort, because this guidance must be able to compensate for the length of the section of the drive belts that wraps around the outer circumference of the winder, depending on the increasing winding diameter.
  • the wrap angle of the drive belts is not constant in this device.

  • the seesaw has two sides Longitudinal bars 16, 17, which are spanned by a sliding table 18 in the area between the deflection rollers 12, 13, so that the upper, conveyor-effective strand of the three belts 19 (FIG. 2) of the belt conveyor 11 does not undergo any deflection.
  • a spring arrangement acts on the rocker, for example a gas spring 20, which tends to press the belt conveyor 11 upwards, conversely the belt conveyor being pushed back against the spring force by the growing winding.

  • the belt conveyor 11 underlies the shingled stream S approximately in its longitudinal center with a narrow winding belt 21 drawn off from a braked supply roll (not shown) and wrapped around the driven deflection roller 12, which thus runs in tensioned state with the shingled stream S: the shingled stream S and the winding belt 21 arrive together at a winding 23 forming on a winding core 22, the peripheral speed of which is of course determined by the winding tape 21.
  • the annular winding core 22 has at its ends bent end flanges 24 whose spacing from one another corresponds approximately to the width of the newspapers Z measured transversely to the conveying direction.
  • an all-round rail 25 with a U-shaped cross section open to the inside is firmly anchored in the center of the inside of the winding core 22.

  • This bearing arrangement 26 initially has two double rollers 27, 28, which are freely rotatably supported in bearing blocks 29 and 30, which bearing blocks are each mounted on a bracket 32 or 33 which projects laterally from a lateral machine frame 31.

  • the bearing block 35 is mounted extending downward on the underside of a boom 36 which is pivotable and displaceable with respect to the frame 31.
  • the piston rod 38 of a fluidic unit 39 is articulated on the boom 36 at 37, the cylinder 40 of which is suspended at 41 between the arms 32 and 33 so that it can swing.
  • Further means, not shown, are provided for displacing the boom 36 towards and away from the frame 31 by a limited amount, so that the double roller 34 moves away from the engagement position shown in solid lines in FIG. 2, in which the double roller 34 is also in the open side of the rail 25 engages, into which the release position shown in broken lines in FIG. 2 can be moved.
  • the winding core is thus clearly freely accessible at all times from the side that appears on the right in FIG. 2, for example by means of a forklift.
  • the winding core 22 is freely rotatably supported at three points, it being noted that the double roller 34, in the engaged position, presses the winding core 22 down and thus prevents it from being lifted off the double rollers 27, 28.

  • a change in the toe-in of the friction wheels 53, 54 could also be achieved in that the support brackets 47, 48, on which the angular gears 71 and 72 and the fluidic units 55 and 56 are mounted, somewhat in one direction or another about the axes the sprockets 69 and 70 are mounted on the boom 44 or on the carriage 43.

Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Aufwickeln eines kontinuierlich anfallenden Schuppenstromes von biegsamen Flächengebilden, insbesondere von gefalteten Druckprodukten zu einem Wickel gemäss dem Oberbegriff des Patentanspruches 1.The present invention relates to a device for winding up a continuously occurring stream of flakes of flexible sheet-like structures, in particular of folded printed products, to form a roll according to the preamble of patent claim 1.

Vergleichbare Einrichtungen sind beispielsweise aus dem DE-GM 6 608 411 und aus der DE-PS 2 544 135 bekannt. Mit diesen vorbekannten Einrichtungen werden allerdings in Schuppenformation anfallende Säcke, Beutel und ähnliche flache Werkstücke und nicht gefaltete Druckprodukte, beispielsweise Zeitungen, zu sogenannten "Schuppenbandrollen" aufgewickelt. Diese Feststellung ist deshalb am Platze, weil die mit den vorbekannten Einrichtungen aufgewickelten Werkstücke praktisch nicht kompressibel sind, während gefaltete Druckprodukte bis zu einem gewissen Grad kompressible Gebilde darstellen.Comparable devices are known for example from DE-GM 6 608 411 and from DE-PS 2 544 135. With these previously known devices, however, sacks, pouches and similar flat workpieces and non-folded printed products, for example newspapers, resulting in scale formation are wound into so-called "scale tape rolls". This determination is due to the fact that the workpieces wound with the previously known devices are practically incompressible, while folded printed products represent compressible structures to a certain degree.

Bei der Einrichtung gemäss dem DE-GM 6 608 411 sind die Mittel zum reibschlüssigen Antreiben des Wickels im Bereich seines Umfanges (nachstehend kurz "Wickelantrieb" genannt) durch eine angetriebene Walze gebildet, auf der der Wickel durch sein Eigengewicht aufliegt, wobei der Wickel frei drehbar am einen Ende einer Pendelschwinge gehaltert ist. Die mit diesem Wickelantrieb übertragbaren Antriebskräfte sind vergleichsweise gering, weil die Uebertragung theoretisch nur an der gemeinsamen Mantellinie zwischen der Mantelfläche der Walze und jener des Wickels erfolgt. Ueberdies wäre dieser Antrieb für Druckproduktewickel schon deswegen nicht geeignet, weil mit dem unvermeidlichen Schlupf das Risiko des Verschmierens der Druckfarbe auf der Flachseite der Druckprodukte einhergeht. Ausserdem ist bei dieser Einrichtung von Nachteil, dass die Höhe des fertiggestellten Wickels bzw. dessen Wickelkernes vom Aussendurchmesser des fertigen Wickels abhängig ist, da der Wickel, wie bereits gesagt, frei drehbar am einen Ende einer Pendelschwinge gehalten ist, während der Aussendurchmesser des fertigen Wickels von der Anzahl und der Dicke der im Wickel vorhandenen Produkte abhängig ist. Daher sind zum Entfernen eines fertigen Wickels, der ein ganz beträchtliches Gewicht aufweisen kann, bei dieser bekannten Einrichtung entweder bodengebundene Hebemittel erforderlich, die auf verschiedene Höhen des Wickelkernes einstellbar sind, oder aber Ueberkopf-Hebezeuge. Solche Ueberkopf-Hebezeuge können aber bestenfalls die fertigen Wickel nur an eine Stelle in derselben Halle transportieren, in der die Einrichtung aufgestellt ist, jedoch nicht durch Türöffnungen, so dass ein Umladen der Wickel erforderlich ist.In the device according to DE-GM 6 608 411, the means for frictionally driving the winding in the area of its circumference (hereinafter referred to as "winding drive") are formed by a driven roller on which the winding rests by its own weight, the winding being free is rotatably supported at one end of a swing arm. The drive forces that can be transmitted with this winding drive are comparatively low, because the transmission takes place theoretically only at the common surface line between the surface of the roller and that of the winding. Moreover, this drive would not be suitable for printing product winding because the inevitable slippage entails the risk of the ink smearing on the flat side of the printing product. A further disadvantage of this device is that the height of the finished winding or its winding core depends on the outside diameter of the finished winding, since, as already mentioned, the winding is held freely rotatably at one end of a swing arm while the outside diameter of the finished winding depends on the number and thickness of the products present in the winding. Therefore, to remove a finished roll, which can have a very considerable weight, either ground-based lifting means, which can be adjusted to different heights of the winding core, or overhead hoists are required in this known device. Such overhead hoists can at best only transport the finished rolls to one place in the same hall in which the device is installed, but not through door openings, so that the rolls must be reloaded.

Die zuletzt genannten Nachteile sind wenigstens zum Teil bei der Einrichtung gemäss der DE-PS 2 544 135 insofern behoben, als der Wickelkern und damit auch der Wickel frei drehbar in ortsfesten Lagerböcken gehalten ist. Bei der Einrichtung der DE-PS erfolgt der Wickelantrieb durch zwei den Wickel teilweise umschlingende, angetriebene Druckbänder. Bei dieser Einrichtung ist von Nachteil, dass die Führung der Antriebsbänder eines erheblichen technischen Aufwandes bedarf, weil diese Führung imstande sein muss, die sich nach Massgabe des wachsenden Wickeldurchmessers stark verändernde Länge des jeweils den Wickelaussenumfang umschlingenden Abschnittes der Antriebsbänder zu kompensieren. Ausserdem ist bei dieser Einrichtung der Umschlingungswinkel der Antriebsbänder nicht konstant. Wenngleich bei dem Wickelantrieb der Einrichtung gemäss der DE-PS 2 544135 im Falle von Druckprodukten die Gefahr des Verschmierens des Druckes möglicherweise geringer ist als bei der Einrichtung gemäss des bereits gewürdigten DE-GM 6 608 411, besteht doch die Gefahr, dass bei der unvermeidlichen Verschmutzung des Antriebsbandes die aufgewickelten Flächengebilde auch verschmutzt werden. Auch bei dieser vorbekannten Einrichtung ist das Entfernen eines fertigen Wickels nicht ohne Probleme, muss doch hierzu zuerst das Antriebsband vom Umfang des Wickels gelöst werden.The last-mentioned disadvantages are at least partially eliminated in the device according to DE-PS 2 544 135 insofar as the winding core and thus also the winding is held freely rotatably in fixed bearing blocks. When the DE-PS is set up, the winding drive is carried out by two driven pressure belts which partially wrap around the winding. The disadvantage of this device is that the guidance of the drive belts requires considerable technical effort, because this guidance must be able to compensate for the length of the section of the drive belts that wraps around the outer circumference of the winder, depending on the increasing winding diameter. In addition, the wrap angle of the drive belts is not constant in this device. Although with the winding drive of the device according to DE-PS 2 544135 in the case of printed products the risk of smearing the pressure may be lower than with the device according to DE-GM 6 608 411, which has already been recognized, there is a risk that the inevitable Contamination of the drive belt, the coiled fabrics can also be contaminated. Even with this previously known device, the removal of a finished roll is not without problems, for this purpose the drive belt must first be released from the circumference of the roll.

Bei diesem Stand der Technik ist es als eine Aufgabe der Erfindung anzusehen, eine Einrichtung der eingangs genannten Art zu schaffen, die bei Erhaltung der Vorteile des umfangsseitigen Wickelantriebes (im wesentlichen konstante Antriebsgeschwindigkeit) einen vergleichsweise einfachen Aufbau aufweist und bei der eine Beeinträchtigung irgendwelcher Art der Flachseiten der Flächengebilde durch den Wickelantrieb ausgeschlossen ist.In this prior art, it is an object of the invention to provide a device of the type mentioned, which has a comparatively simple structure while maintaining the advantages of the peripheral winding drive (essentially constant drive speed) and in which an impairment of any kind Flat sides of the fabrics are excluded by the winding drive.

Diese Aufgabe ist bei der vorgeschlagenen Einrichtung dadurch gelöst, dass sie die im Kennzeichen des Patentanspruches 1 definierten Merkmale aufweist.This object is achieved in the proposed device in that it has the features defined in the characterizing part of patent claim 1.

  • 1 is a schematic side view of a device in which only the essential components are shown,
  • 2 on an enlarged scale partially a section along the line 11-11 of FIG. 1, but certain parts appear in a view from the left of FIG. 1,

Es sei vorerst auf die Fig. 1 bis 3 Bezug genommen. Bei der dargestellten Einrichtung 10 erkennt man einen Bandförderer 11, der zwei Umlenkrollen 12, 13 aufweist, von denen die Umlenkrolle 12 über eine Kette 14 angetrieben ist. Die Umlenkrollen 12, 13 sind an den Enden einer Wippe gelagert, die um die Achse 15 der angetriebenen Umlenkrolle 12 verschwenkbar ist. Die Wippe weist zwei seitliche Längsholme 16, 17 auf, die im Bereich zwischen den Umlenkrollen 12, 13 durch einen Gleittisch 18 überspannt sind, damit das obere, förderwirksame Trum der drei Riemen 19 (Fig. 2) des Bandförderers 11 keine Durchbiegung erfährt. An der Wippe greift eine Federanordnung, beispielsweise eine Gasfeder 20 an, die bestrebt ist, den Bandförderer 11 nach oben zu drücken, wobei umgekehrt der Bandförderer von dem wachsenden Wickel gegen die Federkraft zurückgedrängt wird.For the time being, reference is made to FIGS. 1 to 3. In the device 10 shown, a belt conveyor 11 can be seen, which has two deflection rollers 12, 13, of which the deflection roller 12 is driven via a chain 14. The deflection rollers 12, 13 are mounted at the ends of a rocker which can be pivoted about the axis 15 of the driven deflection roller 12. The seesaw has two sides Longitudinal bars 16, 17, which are spanned by a sliding table 18 in the area between the deflection rollers 12, 13, so that the upper, conveyor-effective strand of the three belts 19 (FIG. 2) of the belt conveyor 11 does not undergo any deflection. A spring arrangement acts on the rocker, for example a gas spring 20, which tends to press the belt conveyor 11 upwards, conversely the belt conveyor being pushed back against the spring force by the growing winding.

Der Bandförderer 11 übernimmt von einem in Fig. 1 links nur schematisch angedeuteten Zuförderer einen Schuppenstrom S von gefalteten Zeitungen Z, von denen jede mit ihrem vorlaufenden Falz oder Bund die Schnittkante oder Blume der vorangehenden Zeitung überlappt. Gleichzeitig unterlegt der Bandförderer 11 den Schuppenstrom S etwa in seiner Längsmitte mit einem von einer nicht dargestellten, gebremsten Vorratsrolle abgezogenen und die angetriebene Umlenkrolle 12 umschlingenden schmalen Wickelband 21, das somit in gespanntem Zustand mit dem Schuppenstrom S mitläuft: Der Schuppenstrom S und das Wickelband 21 gelangen zusammen zu einem auf einem Wickelkern 22 sich bildenden Wickel 23, dessen Umfangsgeschwindigkeit natürlich durch das Wickelband 21 bestimmt wird.The belt conveyor 11 takes over a shingled stream S of folded newspapers Z from a feed conveyor indicated only schematically on the left in FIG. 1, each of which overlaps the cut edge or flower of the preceding newspaper with its leading fold or collar. At the same time, the belt conveyor 11 underlies the shingled stream S approximately in its longitudinal center with a narrow winding belt 21 drawn off from a braked supply roll (not shown) and wrapped around the driven deflection roller 12, which thus runs in tensioned state with the shingled stream S: the shingled stream S and the winding belt 21 arrive together at a winding 23 forming on a winding core 22, the peripheral speed of which is of course determined by the winding tape 21.

Der Fig. 2 ist zu entnehmen, dass der ringförmige Wickelkern 22 an seinen Enden nach innen umgebogene Endflansche 24 aufweist, deren Abstand voneinander etwa der quer zur Förderrichtung gemessenen Breite der Zeitungen Z entspricht. Ausserdem ist mittig an der Innenseite des Wickelkernes 22 eine rundum laufende Schiene 25 mit einem U-förmigen, nach innen offenen Querschnitt fest verankert. Diese Schiene 25 dient einerseits zur radialen Versteifung des relativ dünnwandigen Wickelkernes 22, andererseits und vor allem um den Wickelkern auf konstanter Höhe drehbar in der nachstehend zu beschreibenden Lageranordnung 26 zu haltern und zu führen.It can be seen from FIG. 2 that the annular winding core 22 has at its ends bent end flanges 24 whose spacing from one another corresponds approximately to the width of the newspapers Z measured transversely to the conveying direction. In addition, an all-round rail 25 with a U-shaped cross section open to the inside is firmly anchored in the center of the inside of the winding core 22. This rail 25 is used on the one hand for the radial stiffening of the relatively thin-walled winding core 22, on the other hand and above all in order to hold and guide the winding core rotatably at a constant height in the bearing arrangement 26 to be described below.

Diese Lageranordnung 26 weist zunächst zwei Doppelrollen 27, 28 auf, die frei drehbar in Lagerböcken 29 bzw. 30 gelagert sind, welche Lagerböcke auf je einem von einem seitlichen Maschinengestell 31 seitlich abstehenden Ausleger 32 bzw. 33 montiert sind. Der Wickelkern 22 ruht nun so auf den Doppelrollen 27, 28, dass diese in die offene Seite der Schiene 25 eingreifen.This bearing arrangement 26 initially has two double rollers 27, 28, which are freely rotatably supported in bearing blocks 29 and 30, which bearing blocks are each mounted on a bracket 32 or 33 which projects laterally from a lateral machine frame 31. The winding core 22 now rests on the double rollers 27, 28 such that they engage in the open side of the rail 25.

Die Lageranordnung 26 weist eine weitere Doppelrolle 34 auf, die ebenfalls frei drehbar in einem Lagerbock 35 gelagert ist. Der Lagerbock 35 ist nach unten sich erstreckend an der Unterseite eines Auslegers 36 montiert, der in bezug auf das Gestell 31 schwenkbar und verschiebbar ist. Zum Verschwenken ist am Ausleger 36 bei 37 die Kolbenstange 38 eines Fluidik-Aggregates 39 angelenkt, dessen Zylinder 40 bei 41 zwischen den Auslegern 32 und 33 pendelfähig aufgehängt ist. Nicht dargestellte weitere Mittel sind vorgesehen, um den Ausleger 36 um ein beschränktes Mass in Richtung zum Gestell 31 hin und von diesem weg zu verschieben, so dass die Doppelrolle 34 von der in Fig. 2 ausgezogen dargestellten Eingriffslage, in der die Doppelrolle 34 ebenfalls in die offene Seite der Schiene 25 eingreift, in die in Fig. 2 strichpunktiert eingezeichnete Freigabestellung bewegbar ist. Damit ist klarerweise der Wickelkern jederzeit von der in Fig. 2 rechts erscheinenden Seite her frei zugänglich, beispielsweise mittels eines Gabelstaplers.The bearing arrangement 26 has a further double roller 34, which is likewise freely rotatably mounted in a bearing block 35. The bearing block 35 is mounted extending downward on the underside of a boom 36 which is pivotable and displaceable with respect to the frame 31. For pivoting, the piston rod 38 of a fluidic unit 39 is articulated on the boom 36 at 37, the cylinder 40 of which is suspended at 41 between the arms 32 and 33 so that it can swing. Further means, not shown, are provided for displacing the boom 36 towards and away from the frame 31 by a limited amount, so that the double roller 34 moves away from the engagement position shown in solid lines in FIG. 2, in which the double roller 34 is also in the open side of the rail 25 engages, into which the release position shown in broken lines in FIG. 2 can be moved. The winding core is thus clearly freely accessible at all times from the side that appears on the right in FIG. 2, for example by means of a forklift.

Durch die Lageranordnung 26 ist der Wickelkern 22 an drei Stellen frei drehbar gelagert, wobei zu bemerken ist, dass die Doppelrolle 34 in Eingriffslage den Wickelkern 22 nach unten drückt und so dessen Abheben von den Doppelrollen 27, 28 verhindert.Due to the bearing arrangement 26, the winding core 22 is freely rotatably supported at three points, it being noted that the double roller 34, in the engaged position, presses the winding core 22 down and thus prevents it from being lifted off the double rollers 27, 28.

Nachstehend sollen die Mittel beschrieben werden, die den Wickelkern 22 bzw. den darauf sich bildenden Wickel so in Umlauf bringen, dass der anfallende Schuppenstrom S aufgewickelt wird.The means which circulate the winding core 22 or the winding formed thereon in such a way that the resulting shingled stream S is wound will be described below.

In einer am Gestell 31 montierten Führungsschiene 42 ist ein mit einem den Bandförderer 11 unten überspannenden Ausleger 44 versehener Wagen 43 auf nicht näher dargestellte Weise auf und ab verschiebbar gelagert. Der Ausleger 44 ist zu beiden Seiten des Bandförderers 11 über eine Gelenkkoppel 45 bzw. 46 an die Längsholme 16 bzw. 17 des Bandförderers gekoppelt. Mithin folgt also der Ausleger 44 mit dem Wagen 43 zwangsläufig der Auf- und Ab-Bewegung des Bandförderers 11.In a guide rail 42 mounted on the frame 31, a carriage 43, which is provided with a cantilever 44 spanning the belt conveyor 11 at the bottom, is slidably mounted up and down in a manner not shown. The boom 44 is coupled to the longitudinal bars 16 and 17 of the belt conveyor on both sides of the belt conveyor 11 via an articulated coupling 45 and 46, respectively. Thus, the boom 44 with the carriage 43 inevitably follows the up and down movement of the belt conveyor 11.

An seinen beiden Enden ist der Ausleger 44 mit nach oben sich erstreckenden Aufhängungen oder Tragkonsolen 47, 48 versehen. An diesen Tragkonsolen 47, 48 ist das eine Ende der Gelenkkoppeln 45 bzw. 46 angelenkt. Auf beiden Tragkonsolen 47, 48 ist bei 49 bzw. 50 je ein Winkelhebel 51 bzw. 52 angelenkt, wobei am Ende dessen längeren Armes ein Reibrad 53 bzw. 54 drehbar gelagert ist, während am Ende seines kürzeren Armes ein ebenfalls an der Konsole 47 bzw. 48 montiertes Fluidik-Aggregat 55 bzw. 56 angreift. Die Fluidik-Aggregate 55, 56 dienen dazu, die Reibräder 53, 54 an die Stirnflansche 24 bzw. an die flache Stirnseite des sich bildenden Wickels 23 anzudrücken und auch dazu, wie beispielsweise in Fig. 3 gestrichelt angegeben, die Reibräder 53, 54 zur Freigabe des Wickels 23 voneinander zu entfernen.At both ends of the boom 44 is provided with upwardly extending suspensions or support brackets 47, 48. One end of the articulated couplings 45 and 46 is articulated on these support brackets 47, 48. An angle lever 51 or 52 is articulated on each of the two support brackets 47, 48 at 49 and 50, a friction wheel 53 and 54 being rotatably mounted at the end of its longer arm, while at the end of its shorter arm there is also a bracket 47 or 48 mounted fluidic unit 55 or 56 attacks. The fluidic units 55, 56 serve to press the friction wheels 53, 54 against the end flanges 24 or against the flat end face of the winding 23 that is being formed, and also for this purpose, as indicated by dashed lines in FIG. 3, for the friction wheels 53, 54 Release of the winding 23 to be removed from each other.

Der Antrieb der Reibräder 53, 54 ist nachstehend unter weitgehender Bezugnahme auf Fig. 1 und 2 beschrieben. Beidseits der angetriebenen Umlenkrolle 12 des Bandförderers 11 ist eine Kupplung 57, 58, beispielsweise eine Rutschkupplung, angeordnet, deren eine Hälfte drehfest mit der Umlenkrolle 12 verbunden ist und deren andere Hälfte ein Kettenrad 59 bzw. 60 trägt. Von den Kettenrädern 59, 60 führt je eine Kette 61 bzw. 62 zu einem Kettenrad 63 bzw. 64, das drehbar am Anlenkpunkt der Gelenkkoppel 45 bzw. 46 am Längsholm 16 bzw. 17 gelagert ist. Mit dem Kettenrad 63 bzw. 64 ist ein weiteres Kettenrad 65 bzw. 66 verbunden. Von diesem Kettenrad 65 bzw. 66 führt eine parallel zur Gelenkkoppel 45 bzw. 46 laufende Kette 67 bzw. 68 zu einem zum Anlenkpunkt der Gelenkkoppel 45 bzw. 46 an der Tragkonsole 47 bzw. 48 koaxialen Kettenrad 69 bzw. 70, das das Antriebsrad eines Winkelgetriebes 71 bzw. 72 ist. Das Abtriebsrad 73 bzw. 74 dieses Winkelgetriebes 71 bzw. 72 ist koaxial zum Gelenkzapfen 49 bzw. 50 des Winkelhebels 51 bzw. 52 und treibt eine Kette 75 bzw. 76, die ein drehfest und koaxial mit dem Reibrad 53 bzw. 54 verbundenes Kettenrad 77 bzw. 78 umschlingt.The drive of the friction wheels 53, 54 is described below with extensive reference to FIGS. 1 and 2. A clutch 57, 58, for example a slip clutch, is arranged on both sides of the driven deflection roller 12 of the belt conveyor 11, one half of which is non-rotatably connected to the deflection roller 12 and the other half of which carries a chain wheel 59 or 60. A chain 61 or 62 leads from the sprockets 59, 60 to a sprocket 63 or 64, which is rotatably mounted at the articulation point of the articulated coupling 45 or 46 on the longitudinal spar 16 or 17. Another sprocket 65 or 66 is connected to the sprocket 63 or 64. From this chain wheel 65 or 66, a chain 67 or 68 running parallel to the articulated coupling 45 or 46 leads to a chain wheel 69 or 70 which is coaxial to the articulation point of the articulated coupling 45 or 46 on the support bracket 47 or 48 and which is the drive wheel of a Angular gear 71 or 72 is. The driven wheel 73 or 74 of this angular gear 71 or 72 is coaxial to the pivot pin 49 or 50 of the angle lever 51 or 52 and drives a chain 75 or 76 which has a sprocket 77 connected in a rotationally fixed and coaxial manner to the friction wheel 53 or 54 or 78 wraps around.

Das Uebersetzungsverhältnis im Winkelgetriebe 71 bzw.72 ist auf eine Umfangsgeschwindigkeit der Reibräder 53, 54 ausgelegt, die etwa so gross oder etwas grösser als die Umfangsgeschwindigkeit des Wickels ist. Da aber die Reibräder nicht am äussersten Wickelumfang angreifen, ist diese Umfangsgeschwindigkeit notwendigerweise etwas geringer als jene am äussersten Wickelumfang, so dass nach Massgabe der Rutschkupplung 57 bzw. 58 das Wickelband 21 - wie bereits erwähnt - in gespanntem Zustand mit dem Schuppenstrom S mitläuft. Selbst bei einem grossen Wickelverhältnis bleibt dabei die Geschwindigkeitsdifferenz zwischen Reibradumfang und Wickelumfang gering und praktisch konstant, da die Reibräder sich stets im Berührungsbereich des Bandförderers 11 mit dem Wickelumfang befinden, indem sie vom wachsenden Wickel über die Wippe nachgeführt werden.The transmission ratio in the angular gear 71 or 72 is designed for a peripheral speed of the friction wheels 53, 54 which is approximately as large or slightly greater than the peripheral speed of the winding. However, since the friction wheels do not attack the outermost wrap circumference, this circumferential speed is necessarily somewhat lower than that on the outermost wrap circumference, so that, as already mentioned, the winding tape 21 runs along with the shingled stream S in a tensioned state according to the slip clutch 57 or 58. Even with a large winding ratio, the speed difference between the friction wheel circumference and the winding circumference remains small and practically constant, since the friction wheels are always in the area of contact of the belt conveyor 11 with the winding circumference by being tracked by the growing winding over the rocker.

Aus Fig. 1 lässt sich herleiten, dass dabei die Achsen der Reibräder 53, 54 sich stets in einer Radialebene des Wickels 23 befinden. Dies dank der Führungsschiene 42, die eine geradlinige Führung der Auf- und Ab-Bewegung des Auslegers 44 gewährleistet, obwohl der Bandförderer 11 und damit dessen Längsholme 16, 17 eine Schwenkbewegung durchführen. In der in Fig. 1 bis 3 dargestellten Ausführung übertragen somit die Reibräder 53, 54 einen Antrieb, der nur in Umfangsrichtung wirkt. Dazu sind die Reibräder mit einem Reibbelag 53', 54' versehen, der in der Art eines Fahrzeugreifens oder Pneus ausgebildet sein kann.From Fig. 1 it can be deduced that the axes of the friction wheels 53, 54 are always in a radial plane of the winding 23. This is thanks to the guide rail 42, which ensures straight-line guidance of the up and down movement of the boom 44, although the belt conveyor 11 and thus its longitudinal bars 16, 17 perform a pivoting movement. In the embodiment shown in FIGS. 1 to 3, the friction wheels 53, 54 thus transmit a drive which acts only in the circumferential direction. For this purpose, the friction wheels are provided with a friction lining 53 ', 54', which can be designed in the manner of a vehicle tire or tire.

Wenn nun gewünscht ist, dass auf die flachen Stirnseiten des sich bildenden Wickels 23 neben der nur in Umfangsrichtung wirkenden Antriebskraft noch eine weitere Kraftkomponente wirken soll, beispielsweise um den Wickel zu verdichten, kann dies z.B. dadurch geschehen, dass den Reibrädern 53, 54 in Bezug auf ihren Abrollpunkt an der Stirnseite des Wickels 23 eine gewisse "Vorspur" gegeben wird. Dazu genügt es im vorliegenden Beispiel, die in Fig. 1 lotrecht am Gestell 31 befestigte Führungsschiene 42 geneigt am Gestell zu befestigen.If it is now desired that, in addition to the driving force acting only in the circumferential direction, a further force component should act on the flat end faces of the winding 23 that is being formed, for example in order to compress the winding, this can e.g. by the fact that the friction wheels 53, 54 are given a certain "toe-in" with respect to their roll-off point on the end face of the winding 23. For this it is sufficient in the present example to incline the guide rail 42, which is vertically fastened to the frame 31 in FIG. 1, on the frame.

Wenn diese Führungsschiene 42 in Fig. 1 etwas im Gegenuhrzeigersinn verdreht am Gestell befestigt wird, ergibt sich die in ausgezogenen Linien in Fig. 4 schematisch dargestellte Situation. Die strichpunktierte Linie 79 ist die Richtung des Radius des Wickels 23, während die strichpunktierte Linie 80 die Richtung der Achsen der Reibräder 53, 54 darstellt. In dieser Lage üben die Reibräder 53, 54 neben der in Umfangsrichtung wirkenden Kraft - wie die Feder 20 - auch eine nach der Mitte des Wickels 23 gerichtete Kraftkomponente aus.If this guide rail 42 in FIG. 1 is attached to the frame in a somewhat counterclockwise direction, the situation shown schematically in solid lines in FIG. 4 results. The dash-dotted line 79 is the direction of the radius of the winding 23, while the dash-dotted line 80 represents the direction of the axes of the friction wheels 53, 54. In this position, the friction wheels 53, 54 exert not only the force acting in the circumferential direction - like the spring 20 - but also a force component directed towards the center of the winding 23.

Wenn die Führungsschiene 42 dagegen etwas im Uhrzeigersinn in Fig. 1 verdreht am Gestell 31 befestigt wird, ergibt sich die in Fig. 4 strichpunktiert angegebene Situation, in der die strichpunktierte Linie 80' die Richtung der Achsen der Reibräder angibt.If, on the other hand, the guide rail 42 is fastened to the frame 31 in a somewhat clockwise direction in FIG. 1, the situation shown in broken lines in FIG. 4 results, in which the chain line 80 ′ indicates the direction of the axes of the friction wheels.

Ebenso könnte eine Aenderung der Vorspur der Reibräder 53, 54 dadurch erreicht werden, dass die Tragkonsolen 47, 48, auf denen die Winkelgetriebe 71 bzw. 72 und die Fluidikaggregate 55 bzw. 56 montiert sind, etwas in der einen oder anderen Richtung um die Achsen der Kettenräder 69 bzw. 70 am Ausleger 44 oder am Wagen 43 montiert werden. Dabei würde die Führungsschiene 42 nach wie vor die Reibräder 53, 54 bezüglich des Wickels 23 nach Massgabe dessen Wachstums in exakt radialer Richtung nachführen.A change in the toe-in of the friction wheels 53, 54 could also be achieved in that the support brackets 47, 48, on which the angular gears 71 and 72 and the fluidic units 55 and 56 are mounted, somewhat in one direction or another about the axes the sprockets 69 and 70 are mounted on the boom 44 or on the carriage 43. In this case, the guide rail 42 would continue to track the friction wheels 53, 54 with respect to the winding 23 in accordance with its growth in an exactly radial direction.

In Fig. 5 ist schematisch eine Ausführungsvariante der Reibräder dargestellt. Bei dieser Ausführungsvariante kreuzen die Achsen der Reibräder 53A, 54A die Achse des Wickelkernes nicht im rechten, sondern in einem spitzen Winkel. Die Reibräder 53A, 54A sind daher umfangsseitig an ihrer dem Wickel 23 zugekehrten Flachseite mit dem Reibbelag 53' bzw. 54' versehen. Ausserdem ist der Angriffspunkt der Reibräder 53A, 54A an den flachen Stirnseiten des Wickels 23 bzw. an den Endflanschen 24 auf der bezüglich ihrer Achsen von der Achse des Wickels 23 entfernteren Seite. Der Vorteil dieser Reibräder 53A, 54A wird darin gesehen, dass der Antrieb des Wickels längs eines Berührungsbogens erfolgt, wobei dieser Bogen dank der Walkbarkeit der Reibbeläge 53', 54' sozusagen konzentrisch zum Wickel 23 sein kann.An embodiment variant of the friction wheels is shown schematically in FIG. 5. In this embodiment variant, the axes of the friction wheels 53A, 54A do not cross the axis of the winding core at a right angle, but at an acute angle. The friction wheels 53A, 54A are therefore provided on the circumferential side with the friction lining 53 'and 54' on their flat side facing the winding 23. In addition, the point of application of the friction wheels 53A, 54A is on the flat end faces of the winding 23 or on the end flanges 24 on the side which is more distant from the axis of the winding 23 with respect to their axes. The advantage of these friction wheels 53A, 54A is seen in the fact that the winding is driven along a contact curve, which curve can be concentric to the winding 23, so to speak, thanks to the flexibility of the friction linings 53 ', 54'.

Abgesehen vom Wickelband 21, das umfangsseitig mit dem Schuppenstrom S zum Wickel 23 aufgewickelt wird, bleibt die Aussenseite oder Mantelfläche des Wickels 23 unberüht. Die Reibräder 53, 54 greifen an Stellen der Zeitungen an, wo keine Druckfarbe ist. Die Zeitungen S werden beim Aufwickeln nur durch ihr Eigengewicht und durch das Wickelband 21 quer zu ihrer Flachseite gepresst, nicht aber durch die für den Antrieb erforderlichen Anpresskräfte für die Reibräder. Die Reibräder 53, 54 haben noch eine ausgleichende Funktion, so dass der entstehende Wickel 23 vollkommen ebene Stirnseiten aufweist.Apart from the winding tape 21, which is wound around the circumference with the shingled stream S to form the winding 23, the outside or outer surface of the winding 23 remains unaffected. The friction wheels 53, 54 attack in places of the newspapers where there is no printing ink. The newspapers S are pressed during winding only by their own weight and by the winding belt 21 transversely to their flat side, but not by the pressing forces required for the drive for the friction wheels. The friction wheels 53, 54 still have a compensating function, so that the resulting winding 23 has completely flat end faces.

Der dadurch verwirklichte technische Erfolg zeigt sich besonders deutlich in Gegenüberstellung mit der aus der europäischen Patentanmeldung Nr. 0 135 080 bekanntgewordenen Vorrichtung zum Aufwickeln einer Vielzahl von Druckbogen.The technical success achieved in this way can be seen particularly clearly in comparison with the device for winding up a large number of printed sheets, which has become known from European patent application No. 0 135 080.

Zur Zuführung der letztern ist eine mit einem Förderband versehene Wippe vorgesehen und zum Antrieb des Wickels ein gegen den Wickelumfang anstellbares endloses Antriebsband, wobei das Förderband und das Antriebsband nach der Art einer Zange an etwa diametral einander gegenüberliegenden Stellen an den Wickelumfang anstellbar sind. Das Antriebsband umschlingt einen Teil des Wickelumfanges unter Ausübung eines Druckes, der ganz erheblich ist bzw. sein muss, zumal wenn die mit hoher Geschwindigkeit anfallenden Druckprodukte einer Rotationsdruckmaschine aufgewickelt werden sollen. Dann geht es nämlich nicht nur darum, den Wickel unter Spannung des Wickelbandes überhaupt zu bilden, vielmehr muss der Wickel häufig angehalten und erneut auf Betriebsgeschwindigkeit beschleunigt werden. Soll dies schlupflos gelingen, so muss man das Andrückband mit grosser Kraft an dem Wickelumfang angelegt halten, wobei selbst wenn ein Schlupf vermieden werden könnte, der Druck allein schon zum Durchschlagen und Verschmieren der Druckfarbe führt. Durch die Verwendung von Reibrädern, die an den Stirnseiten des Wickels angreifen, kann diese Gefahr vermieden werden, wobei überraschenderweise der Wickelantrieb trotz der vergleichsweise beschränkten Angriffsfläche der Reibräder mit geringer Anpresskraft tonnenschwere Wickel in Sekundenschnelle zu beschleunigen oder anzuhalten vermag und dann natürlich auch den ordentlichen Wickelvorgang spielend bewältigen kann.To feed the latter, a rocker provided with a conveyor belt is provided, and an endless drive belt that can be adjusted against the winding circumference is provided for driving the winding, the conveyor belt and the drive belt being adjustable in the manner of a pair of pliers at approximately diametrically opposite locations on the winding circumference. The drive belt wraps around part of the winding circumference while exerting a pressure which is or must be quite considerable, especially if the printing products of a rotary printing machine which are produced at high speed are to be wound up. Then it is not just a question of forming the winding under tension of the winding tape at all, rather the winding often has to be stopped and accelerated again to operating speed. If this is to be possible without slippage, the pressure band must be applied to the circumference of the roll with great force, and even if slippage could be avoided, the pressure alone leads to the ink streaking and smearing. This risk can be avoided by using friction wheels which engage on the end faces of the winding, and surprisingly se the winding drive, despite the comparatively limited contact surface of the friction wheels with low contact pressure, is able to accelerate or stop wrapping tons in a matter of seconds and then of course can also master the proper winding process with ease.
