Definitions

  • the invention relates to a winding machine according to the preamble of claim 1.
  • Winding machines of this type also called “pop rollers" generally form the end section of a paper machine in order to bring the paper web obtained there into roll form. However, they are also used to rewind an already finished roll so that a new roll is created.
  • the roll should have very specific properties, especially as far as the winding hardness is concerned.
  • the winding hardness should drop from a certain initial value to an end value.
  • the waste should be as even as possible from the first to the last layer. It should have a certain gradient, i.e. not too strong and not too weak.
  • the course of the winding hardness should under no circumstances have jump points, e.g. a sudden drop.
  • Known means of influencing the winding hardness are two measures that are used, for example, in slitter rewinder.
  • One is to subject the web to a more or less strong tension when winding it up.
  • the other measure is to make the role more or less strong to press on the support roller, for example by applying pressure to the axes of the spool, or by pressing a rider roller, which is arranged parallel to the resulting roll and is pressed against it, so that a line pressure between the roll and the support roller arises.
  • the weight of the spool frequently creates a line pressure between the resulting roll and the support roller.
  • the drum is extremely heavy. It reaches a dead weight of several tons, so that a correspondingly high line pressure is created. This is responsible for the extremely high winding hardness of the core of the roll.
  • a separate drive for the drum i.e. a so-called center drive is advantageous because it is the best way to control the winding hardness.
  • the slide (or the pair of slides) together with the slideways is mounted on a swivel arm so that the slide performs the same swivel movement as the primary lever.
  • the radial distance between the drive and the axis of the support roller must also be increased to the same extent. This is done by adjusting the radial position of the slide (tracking).
  • the carriage has been adjusted by means of a hydraulic control.
  • the distance between the slide of the drive and the reel is continuously measured when passing through the primary section, and the slide is tracked by means of two hydraulic cylinders.
  • Such a control is intrinsically complex.
  • Another difficulty is that the weight of the engine and transmission must be compensated.
  • the invention has for its object to design the radial adjustment or tracking of the carriage so that it is simple in construction, that certain tolerances with regard to the control accuracy can be allowed, and that it works reliably.
  • the production capacity is within very narrow limits. Accordingly, the speed of the increase in the winding diameter can be determined with a definable tolerance, so that the link guide can be fixed once and for all.
  • the remaining tolerance is compensated for by a handlebar coupling which is assigned to the drive and which, due to its design, has low restoring forces.
  • the restoring forces of the clutch increase in proportion to the deflection.
  • the handlebar coupling mentioned is generally switched between the drive and drum. However, if the motor is directly assigned to the reel due to a special design (e.g. transverse flux motor), the handlebar coupling can also be switched between the motor and the transmission.
  • a special design e.g. transverse flux motor
  • a pneumatic cylinder can be provided which acts on the slide and which ensures that the slide always follows the link guide.
  • the sledge is tracked using a lever that is coupled to the secondary levers.
  • the frictional forces of the slide are so low that they do not have a disruptive effect on the linear force of the winding and thus on the winding hardness.
  • the handlebar coupling is essentially constructed as follows: It comprises a first coupling half that rotates with a drive-side part, a second coupling half that rotates with a driven-side part, a first coupling intermediate member, a second coupling intermediate member and a third coupling intermediate member.
  • the first intermediate coupling member can be connected to the drive-side coupling half via a first link and to the output-side coupling half via a second link diametrically opposite the first link.
  • the second intermediate coupling member can be connected to the drive-side coupling half via a third link and to the output-side coupling half via a fourth link diametrically opposite the third link.
  • the third intermediate coupling element is expediently connected to the drive-side coupling half via a fifth link, and to the output-side coupling half via a sixth link.
  • a link coupling according to DE 37 32 705 A1 comes into consideration.
  • a coupling of this type is an all-around movable, almost torsionally rigid coupling, which is suitable for connecting two machine parts to one another, which are highly displaced relative to one another, radially displaced, axially displaced or angularly displaced.
  • FIG. 1 shows the work phase in which a winding 15 is finished and a new winding is to be started.
  • Winding 15 is in position E ', while drum 5 is in position B.
  • drum 5 was already driven by the center drive I and brought to the speed of the carrying drum 2, but only with the opposite direction of rotation.
  • position B the drum is then lowered somewhat radially to position C, so that it comes into contact with the outer surface of the carrying drum 2 for the purpose of winding the web 13.
  • the beginning of the path of the path 13 brought in from the left is wound onto the drum 5 by means of the blowing nozzles 12.
  • the drum or the nascent winding is in contact with the outer surface of the carrier drum.
  • the center drive I also works between B and E by introducing a torque into the drum 5. After the finished reel 15 has been brought into position F, the reel 5 with the new reel also reaches position D. Until position E is reached, the nascent reel is driven both by friction on the drum 2 and by the center drive I. . Only in the last phase between E and E 'there is only a drive by pressing the roll against the support drum 2 and thus by friction.
  • the pop roller according to FIGS. 4 and 5 in turn has the following important components: a carrier drum 2, a drum 5 with a winding 15 located thereon.
  • the winding 15 is shown in dash-dot lines in FIG recognizes. As can be seen, its diameter increases, with the center point of the winding 15 traveling on a curved path 16 around the carrying drum 2 and passing through a primary path until it reaches a position 15 I.
  • the winding 15 is taken over by the secondary levers, not shown, and moves on an essentially horizontal guideway 17 away from the carrying drum 2, being wound up even further and finally reaching its finished diameter.
  • a pressure device is assigned to the drum, which presses it against the carrying drum with the growing winding on it.
  • a drive motor 18 is also assigned to the drum 5. This rests on a carriage 19 which has slideways for guiding the motor 18 as it passes through the primary route. The carriage is connected to the primary levers, not shown, in such a way that it carries out their pivoting movement.
  • a link guide 20 is provided as the radial adjustment of the slide. With this link guide, the carriage 19 is tracked on its way through the primary path in accordance with the increase in the winding diameter.
  • a steering coupling 21 is interposed between the drive motor 18 and the spool, and also a spool coupling 22, which is actuated by an actuating cylinder.
  • a drive 24 is assigned to the carrying drum 2.
  • this pop roller is a swivel cylinder 30 for actuating the primary lever, a return cylinder 31, which exerts the contact pressure on the drum and thus also on the carrying drum, a frame for drum mounting 32, a translation 33 for the primary lever and a parallel guide shaft 34.
