Definitions

  • the invention relates to a method and an apparatus for winding a paper or Cardboard web, the web on a roller, in particular drum, is wound up, the web being guided over a carrying drum and one empty roller, especially drum, in contact with the carrying drum is brought, the movement of the empty roller, in particular Drum, during the change of position from a storage position to Winding position takes place via swivel joints around the axis of the carrying drum and brought an empty roller into a storage position above the carrying drum becomes.
  • Such devices are e.g. known from EP 330 169. Problematic in these devices is that the empty roller, in particular Tambour, with its full weight on the wrapped paper presses what especially with tissue paper crumplings and thus loss of quality brings itself. Furthermore, there is always a risk with these systems that the swiveling movement from the storage position into the operating (winding) position Position the empty roller can slide out of the holder and corresponding Causes damage.
  • Other such devices are from known from EP 0 350 212, which a winding device of a paper or Cardboard web shows. The swivel lever has one at the end Support plate. This is done so that it is in the lower Position can tip down due to its own weight.
  • a Similar device is also known from WO 94/18104.
  • DE 44 01 804 also shows a winding device in which the empty roller by means of a lever taken from a magazine and into a carriage between the full roller and the drum. Only the paper web still running on the full roller is separated and turned the empty roller wound up. The beginning of the paper web is then by means of a Air jet blown so that it can be wound up by the empty roller can.
  • the aim of the invention is to provide a method and an apparatus for of all movements during the change of position of the roller, in particular Reel, are as simple and safe as possible.
  • the invention is concerned a process whereby an angle lever (10) is provided which is connected in an articulated manner to a swivel arm (12) and on which a pressure cylinder (8) for closing or opening a Holding device (6, 7) is provided and the holding of the axes of the empty Roller, especially drum, during the change of position Clamping by means of a pressure cylinder in a holding device, the is attached to the swivel arm rotatable about the axis of the support drum, and the weight of the empty Roller in the storage position by one connected to the swivel arm Pressure cylinder compensated and when changing the roller the empty roller, especially drum, lowered around a pivot point and at the same time the Weight compensation is reduced.
  • This can be a simple Control of the roll change can be achieved with the Soiling a safe change takes place.
  • An advantageous development is characterized in that the Weight compensation is reduced such that the contact line force is set according to a predetermined function.
  • a favorable development of the invention is characterized in that the contact line force is constant during the entire swivel process is held.
  • An advantageous development of the invention is characterized in that that after complete elimination of the weight components on the carrier drum a pulling force on the empty roller through the same pressure cylinder, especially drum, is exerted, with which the desired contact line force is set.
  • An advantageous embodiment of the invention is characterized in that that the holding claws open in the horizontal position of the empty drum and the swivel arm is swiveled back into the receiving position, whereupon the next drum is removed and the new empty drum in whose position is managed. It is also faster and if necessary early reel change even with small reel diameters possible.
  • a favorable embodiment of the invention is characterized in that the holding device for the empty roller, in particular drum, locked becomes. This is how it is opened accidentally during the swiveling process prevented.
  • the invention also relates to a device for winding a paper or cardboard web, the web on a roller, in particular drum, is wound up, the web being guided over a carrying drum and one empty roller, especially drum, in contact with the carrying drum is brought, wherein a swivel arm is provided which about the axis of the Carrier drum is rotatable. It is characterized in that a Angle lever is provided, which is pivotally connected to the swivel arm is and on which a pressure cylinder for closing or opening one attached to the swivel arm Holding device is provided, with another on the swivel arm Pressure cylinder for weight compensation and pressing the empty roller, especially drum, is provided on the support drum.
  • a favorable development of the invention is characterized in that at least one pressure cylinder is a hydraulic cylinder or alternatively one Pneumatic cylinder is.
  • An advantageous embodiment of the invention is characterized in that that the further pressure cylinder is designed as a pressure and pull cylinder.
  • Another advantageous embodiment of the invention is characterized in that that the holding device is pivotable about a pivot point Pawl and has a claw that can be pressed by a pressure cylinder.
  • An advantageous development of the invention is characterized in that that the pawl and the claw snap into one another in the holding position, that they are with each other during the entire swiveling process are mechanically locked.
  • Fig. 2 shows the detail of the support drum
  • Fig. 3 a to 3 f the sequence at Roller change
  • Fig. 4 is an isometric view of a Show rewinder according to the invention.
  • Fig. 1 shows a winding system in which the paper or cardboard web 1 over a support roller 2 passed and from there wound on a roller (drum) 3 becomes.
  • the empty reels 4 are provided and via a Lever 5 fed to a holding device.
  • Fig. 2 now represents the support roller 2 with the swivel device for the empty Drum 4 represents.
  • a cylinder 8 By pressing a cylinder 8 is in the holding device inserted drum 4 clamped by a claw 6 in such a way that the claw engages in a pawl 7 and locks mechanically becomes. This is how the drum 4 becomes during the entire swiveling process always held positively; falling out of the claw 6 will thereby impossible.
  • the claw 6 is via a pivot joint 9 with an angle lever 10 connected.
  • This angle lever 10 is in turn via a swivel joint 11 connected to the swivel arm 12.
  • the drum 4 recorded in the claw 6 by a Printing cylinder 13, which is connected to the angle lever 10 via a swivel joint 14 is compensated, i.e. the cylinder 13 exerts a counterforce to the Supporting roller acting weight component of the drum 4.
  • the Swivel arm 12 is provided with a sprocket Segment 15 and a gear 16 about the axis 17 of the support drum 2nd pivoted.
  • Fig. 3a shows the insertion of the reel 4 in the claw 6. It can be seen that the drum 4 lies loosely in the claw 6.
  • Fig. 3 b represents the closing of the Claw 6 represents.
  • the cylinder 8 presses the claw 6 against the drum 4, wherein the entire rocker arm 10 is pivoted about the pivot 11 and the claw 6 rotated about the hinge 9 and in positive Is brought into contact with the drum 4. Snaps during this movement the pawl 7 in the claw 6, so that a mechanical locking of the Claw 6 takes place and an opening during the pivoting process neither can be done intentionally or unintentionally.
  • the drum 4 is brought into the winding position.
  • the Swivel arm 12 by means of ring gear 15 through the gear 16 around the Axis 17 of the support drum 2 rotated. Put on the drum 4 on the support drum 2 is predetermined by the cam 20.
  • This Function could also be controlled by appropriate control of the cylinder 13 respectively.
  • the pressure of the cylinder 13 becomes Compensation of the weight component of the drum 4 on the Carrier drum 2 slowly reduced until the weight component of the corresponds to the desired contact pressure.
  • the reduction of the compensation force can be done according to a given function. Usually it should be like this can be set that the contact line force of the drum 4 during the entire pivoting process remains constant.
  • FIG. 4 now shows an isometric illustration of a winding system according to FIG Fig. 2, wherein the same parts with the corresponding reference numerals are.
  • the invention is not limited by the examples, e.g. the Swiveling movement not necessarily over a tooth segment and a gear to be controlled.
