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, into a roll according to the preamble of patent claim 1.
  • Comparable devices are known for example from DE-GM 6 608 4ll and from DE-PS 2 544 l35. 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 driving forces that can be transmitted with this winding drive are comparatively low because the transmission is theoretically only possible on the common jacket line between the outer 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 l35 in that the winding core and thus also the winding is held in fixed bearing blocks in a freely rotatable manner.
  • the winding drive is carried out by two driven pressure belts which partially wrap around the winding.
  • a disadvantage of this device is that the guidance of the drive belts requires considerable technical effort because this guidance must be able to to compensate for the length of the section of the drive belts that wraps around the outer circumference of the winding, which changes greatly as the winding diameter increases.
  • the wrap angle of the drive belts is not constant in this device.
  • FIGS. 1 to 3 In the device 10 shown, a belt conveyor 11 can be seen, which has two deflection rollers l2, l3, of which the deflection roller l2 is driven by a chain l4 ben is.
  • the deflection rollers 12, 13 are supported at the ends of a rocker which can be pivoted about the axis 15 of the driven deflection roller 12.
  • the rocker has two lateral 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 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.
  • the belt conveyor 11 supports 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 which wraps 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 end flanges 24 which are bent inwards at its ends and 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, inwardly open cross cut firmly anchored. This rail 25 serves on the one hand for the radial stiffening of the relatively thin-walled winding core 22, and on the other hand and above all to hold and guide the winding core at a constant height in the bearing arrangement 26 to be described below.
  • 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 and 33 which projects laterally from a lateral machine frame 3l.
  • the winding core 22 now rests on the double rollers 27, 28 such that they engage in the open side of the rail 25.
  • 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 bracket 36 which is pivotable and displaceable with respect to the frame 3l.
  • 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 4l 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 3l by a limited amount, so that the double roller 34 moves away from the engaged position shown 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.
  • This clearly means that the winding core is at all times that of FIG. 2 Right side appearing freely accessible, 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 carriage 43 which is provided with a cantilever 44 spanning the belt conveyor 11 at the bottom, is mounted in a manner that is not shown in detail and can be displaced up and down.
  • the boom 44 is coupled on both sides of the belt conveyor 11 via an articulated coupling 45 and 46 to the longitudinal bars 16 and 17 of the belt conveyor.
  • the boom 44 with the carriage 43 inevitably follows the up and down movement of the belt conveyor 11.
  • 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 connected in a rotationally fixed manner to the deflection roller 12 and the other half of which carries a chain wheel 59 or 60.
  • a chain 6l or 62 From the sprockets 59, 60, a chain 6l or 62 leads 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 l6 or l7.
  • Another sprocket 65 or 66 is connected to the sprocket 63 or 64.
  • 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 7l or 72 is.
  • the driven wheel 73 or 74 of this angular gear 7l or 72 is coaxial to the pivot pin 49 or 50 of the angle lever 5l 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.
  • 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.
  • this circumferential speed is necessarily somewhat lower than that on the outermost winding circumference, so that, as already mentioned, the winding band 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.
  • the axes of the friction wheels 53, 54 are always located in a radial plane of the winding 23, thanks to the guide rail 42, which ensures straightforward guidance of the up and down movement of the arm 44, although the belt conveyor 11 and thus its longitudinal bars 16, 17 perform a pivoting movement.
  • the friction wheels 53, 54 thus transmit a drive which acts only in the circumferential direction.
  • the friction wheels are provided with a friction lining 53 ', 54', which can be designed in the manner of a vehicle tire or tire.
  • a variant of the friction wheels is shown schematically in FIG.
  • 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 on their flat side facing the winding 23 with the friction lining 53 'or 54'.
  • 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 arc, which arc can be concentric to the winding 23, so to speak, thanks to the flexibility of the friction linings 53 ', 54'.
  • 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.
  • a rocker provided with a conveyor belt
  • 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 a 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.
  • 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 attack the end faces of the winding.
  • the winding drive despite the comparatively limited contact surface of the friction wheels with low contact pressure, can accelerate or stop the winding of tons in seconds and then of course also the proper winding process can cope easily.
