Definitions

  • the improvement concerns a belt table for those to be transported under shingled Bow according to the preamble of claim 1.
  • a conveyor table for conveying in particular, a shingled stream of sheets is known.
  • this Belt table are elastically deformable conveyor rollers leading into the suction belts Ring elements embedded.
  • the ring elements can by axial displacement of the parts carrying these elements are squeezed so that they are theirs Change diameter. This will reduce the peripheral speed and therefore the belt speed also changed.
  • a disadvantage of the shown The device is that rubber rings are provided as elastic elements. The Resistance to aging of these elements is not sufficient, so that the Adjustment characteristic of the device deteriorates over time.
  • the object of the improvement is therefore a corresponding device create that shows no age wear.
  • a belt table 1 is shown, the two conveyor belts 2 for sheet B. having.
  • the conveyor belts 2 are driven about an axis 3 and by another axis deflected.
  • On the axis 3 there are two deflection rollers 4, 5 arranged.
  • the deflection rollers 4, 5 are adjusting devices 6, 7 assigned.
  • the adjustment devices 6, 7 serve to determine the scope of the Change pulleys 4, 5. It can also suffice here Deflection pulley fixed and the other only adjustable.
  • FIG. 2 A detail of the deflection roller 4 is shown in more detail in FIG. 2.
  • a suction belt 2 is shown above a suction box 8.
  • suction belt 2 and suction box 8 are used to transport the sheet D.
  • the suction belt 2 is redirected on the pulley 4.
  • the suction belt 2 runs over an elastic Expansion element 10.
  • the expansion element 10 is annular. It can for example in the form of a metal bellows element.
  • the Expansion element 10 sits on a guide element 11 of the deflection roller 4 and is by means of a screw connection 12 from a further guide element 13 Deflection roller 4 loaded.
  • the axial bracing takes place via an adjusting shaft 14, which is rotatably mounted within the guide roller 4.
  • the Expansion element 10 has a tread 20 on the circumference and lateral, radial extending flanks 21.
  • the flanks 21 are in the direction the axis of rotation braced against each other to create a Increase in diameter of the tread 20 or an increase in circumference to reach. Since a metallic element has an elasticity, it does but more to a bend, less to a stretch further measures are necessary for an efficient mode of operation meaningful.
  • the expansion element 10 is provided with expansion joints 22 which are transverse to Tread 20 run. The expansion joints open to avoid Voltage peaks each correlating in openings 23 in both sides of the Expansion element 10.
  • the openings 23 are preferably circular. But there are others, the effect of reducing voltage spikes Cross-sectional shapes reaching for the openings 23 are conceivable.
  • the change in diameter is caused by axial bending reached. Due to the pressure on the flanks 21, the bend accordingly Tread parts between the expansion joints 22 to the outside and the expansion joints 22 open in the tangential direction of the tread 20. This makes the circumference the tread 20 increases and the peripheral speed increases leading suction belt 2 increased. A provision has this accordingly opposite effect.
  • the opening of the expansion joints 22 has no disadvantage Effects on the guidance of the suction belt 2.
  • the effect of increasing the diameter can also be radially from the inside the treads 20 acting control elements can be reached.
  • the required largely circular cylindrical shape of the expansion elements 10 is due to their inner Maintain structure.
  • the device is not only for guiding suction belts 2 but by everyone Suitable for transport belts to be provided for sheet transport.
