Definitions

  • the invention relates to a unwind station for the continuous unwinding of a material web, in particular paper or cardboard web, according to the preamble of claim 1 (DE-A-1 574 632).
  • Unwind stations of the type mentioned here serve for the continuous unwinding of a material web from a winding roll and are arranged upstream of a machine for processing the material web, for example a coating machine.
  • a known unwinding station comprises a primary and a secondary unrolling device, which are used to guide a winding roll.
  • a full winding roll is first guided by the primary unwinding device during the unwinding of the material web. From a desired diameter of the winding roll, this is transferred from the primary to the secondary unwinding device.
  • swivel arms are used which can be swiveled around an axis and which engage on both sides of the winding roll and transfer them to the secondary unwinding device by means of a swivel movement.
  • a new, full winding roll is then fed to the primary unwinding device and the material web wound thereon is connected to the material web running off the secondary unwinding device before it is completely unwound.
  • Adhesive device which has an adhesive roller which can be pivoted about an axis, via which the material web running from the secondary unwinding device is guided to the material web processing machine which is seen in the direction of travel of the material web.
  • the adhesive roller is pivoted and pressed onto the winding roller guided by the primary unwinding device.
  • the material web running off the secondary unwinding device is cut off by means of a cutting device.
  • the known unwinding station has the particular disadvantage that, due to the great weight of the winding roll, which can be up to 40 tonnes when the primary unwinding device is transferred to the primary unwinding device, very large forces have to be applied in order to pivot this load. This requires several separate hydraulic cylinders that pivot the very complex and sturdy swivel arms.
  • a further disadvantage is that due to the large space requirement of the swivel constructions used to transfer the winding roll or to move the adhesive device, the dimensions of the unwinding station, that is to say its height and length, are relatively large. The cost of the unwind station is high, particularly due to the swivel construction.
  • DE-A-1 250 709 discloses a roll-off station which has two drives which can be coupled to the winding rolls by means of a cardan shaft or a belt drive.
  • a roll-off station which has the features mentioned in claim 1.
  • This is characterized by an auxiliary drive, with the aid of which torque can be applied to the winding roll during the transfer from the primary unrolling device to the secondary unrolling device.
  • the auxiliary drive which can be displaced together with the winding roll, the unwinding pull of the material web running off the winding roll, in particular during the transfer of the winding roll, can be kept or adjusted to a desired value.
  • the glue point between the two material webs can be guided safely through the processing machine downstream of the unwinding station.
  • An embodiment of the unwinding station is particularly preferred, which is characterized in that the winding roll can be displaced along a first straight line which preferably runs parallel to an imaginary horizontal.
  • a complex swivel arm construction and hydraulic cylinders effecting the swiveling movement, such as are used in the known unwind station, can therefore be dispensed with, so that the construction of the unwind station can be simplified and its overall height and / or length can be reduced.
  • the auxiliary drive is also used when the winding roll is guided by the primary or the secondary unwinding device.
  • the primary and the secondary unwinding device are therefore arranged at the same level, that is, at the same height, so that the winding roll can be transferred with relatively small forces.
  • the horizontal arrangement of the unwinding stations can in particular the construction of the guide device can be simplified.
  • an embodiment of the unwinding station is also preferred, which is characterized in that the adhesive device has at least one adhesive roller which can be displaced along a second straight line by means of a linear guide device. Due to this configuration, the design of the unwind station can be simplified. The small space requirement of the linear guide device is also advantageous, so that there is the possibility of reducing both the length and the height of the unwind station.
  • the unwind station described below is generally related to a machine for processing a web of material, for example Coating machine, calender, slitter or the like, can be used. It is therefore generally spoken below that the unwind station is assigned to a paper web processing machine.
