Definitions

  • the invention relates to a device for winding and unwinding a material web with two spaced-apart stands, in each of which a horizontal clamping head which can be moved into the winding tube is rotatably mounted.
  • Devices of this type in which the roll is clamped axially between the clamping heads during winding or unwinding and is held by these, are used in particular for winding and unwinding paper webs in the paper processing industry.
  • Such unwinding devices are e.g. described in DE-U 8511986 and in DE-A 29 51 336.
  • DE-A 33 08 271 shows winding devices with these features.
  • the invention has for its object to provide a device for the axleless winding or unwinding of rolls, which is able to process heavy rolls without the negative effects described above occur.
  • the load on the roll in the area of the clamping heads can be reduced in such a way that neither crepe folds nor tears occur during winding or unwinding.
  • the position of the support element can be adjusted with the feature of claim 3 depending on the changing diameter of the roll during winding or unwinding and the desired weight relief.
  • Claim 4 contains a structurally advantageous support device.
  • the load on the rollers in the area of the clamping heads can be kept constant during winding or unwinding.
  • claims 6 and 7 contain advantageous options for determining the weight on the clamping heads
  • claims 8 and 9 advantageously combine the roller changing device with the support device.
  • the unwinding device has two stands 1, 2 arranged at a distance from one another transversely to the web running direction, in each of which an angular gear 4, a coupling 5 and a brake generator 6 are fastened on a rolling stand 3.
  • an angular gear 4 On the horizontal shaft of the angular gear 4, a horizontal clamping head 7 for clamping the roll to be unwound (supply roll 8) is attached to the winding tube 9 on the inside in each case.
  • a holding brake 10 is located on the outside of the shaft.
  • the trestles 3 are mounted on a pipe guide 11 and a support roller 12 extending in the web running direction and movable transversely to the web running direction. The movement takes place via a rack and pinion drive 13.
  • a frame 15 which can be moved up and down with a drive in a recess 14 in the floor, in which two deflecting rollers 16 are freely supported transversely to the web running direction at the same distance from the axis of the clamped supply roll 8.
  • the deflection rollers 16 are encircled by an endless belt 17, the upper, horizontal run of which forms the support surface. It can be moved beyond the floor surface in the direction of the clamping heads 7 and lowered to below the floor surface.
  • two alignment rollers 18 are mounted on levers 19 on the two sides facing the stands 1, 2 and can be pivoted downward in the frame 15. In the swiveled-up position, the alignment rollers 18 are at an equidistant distance from the axis of the clamped supply roller 8, this distance is somewhat less than half the distance of the deflection rollers 16 from this axis.
  • a rigid prism can also be used to center a new supply roller 8. This prism would also have to be lowered by the supporting band 17 during weight relief.
  • a strain gauge On the axis of the support roller 12 of a stand 1 or 2, a strain gauge is attached, which emits an electrical voltage proportional to the deflection - and thus to the load - of the axis to a control device which determines the height of the frame 15 - and thus the height of the supporting band 17 - regulates. With the strain gauge the weight on the clamping heads 7 can be measured continuously.
  • This weight can also be determined using weighing devices which are integrated in the stands 1, 2. It is also possible to control the weight relief via a computer as a function of the specific weight of the supply roll 8, its diameter and its width. However, these solutions are more complex than the present regulation, which uses the deflection of the support roller axis as a controlled variable.
  • the two stands 1, 2 are moved apart until the distance between the clamping heads 7 is greater than the supply roll width.
  • the alignment rollers 18 are pivoted up and brought into a position approximately in alignment with the floor surface by moving the frame 15.
  • the roller 8 is then placed on the alignment rollers 18 and centered by them.
  • the roller 8 is then raised so far that the clamping heads 7 can be inserted into the sleeve 9.
  • the alignment rollers 18 are lowered, so that the upper limit of the frame 15 is formed by the belt 17 which rests on the underside of the supply roller 8.
  • the control device raises the frame 15 until the load on the clamping heads 7 is reduced to this value as a result of the weight being relieved by the belt 17.
  • the supporting belt 17 runs during unwinding, so that there is no relative speed between the belt 17 and the paper web. Since the underside of the supply roll 8 moves away from the belt 17 as a result of the decreasing roll diameter during the unwinding, the load increases again.
  • the measuring device registers this increasing load on the stands 1, 2, and the control device raises the frame 15 again until the load is reduced again to 30 kN. This automatic adjustment of the relief is carried out permanently until the total weight of the supply roll 8 falls below the value of 30 kN. Then, after a set waiting time, the frame 15 is lowered with the belt 17, and the unwinding process is completed without relief.
  • a winder support e.g. is described in DE-A 33 08 271, is constructed accordingly. There three rolls are wound up at three winding stations. Each of these winding stations has a support device. The height of the support elements is also regulated as a function of the load on the clamping heads measured in the respective bearing blocks. In this embodiment too, the device for changing the full roll can be combined with the support device.
