Definitions

  • the present invention relates to a Bandumlenkvoriques for angular deflection of bands, in particular metal bands, with a Umlenkzylinder to which the band is deflectable while maintaining the Bandzugs, the band by means of rolling elements, which are arranged on the deflection cylinder along a helical belt surface and form level bearing surfaces, is supported.
  • the individual processing stations are often housed in different halls, which are arranged angularly or reversed to each other.
  • the direction of tape travel in a treatment line must then be changed for manufacturing reasons, often the top and bottom of a tape are turned.
  • An angular deflection and / or reorientation of the strip surfaces, in which the inside or outside of a strip can optionally be supplied as a "good side" to a subsequent process step, is also often required in treatment lines of metal strips.
  • the invention is based on the object to provide a Bandumlenkvortechnisch and a method for band deflection indicate, which requires less technical effort.
  • rollers with different setting are used on the peripheral side of a deflection cylinder: on a half-shell, the rollers are left-handed, arranged on the other side in the right-hand direction.
  • the rollers of one or the other half-shell serve as support surfaces for the strip.
  • the deflection device is thus characterized in that the deflection cylinder between a first operating position and a second operating position is adjustable, each operating position is assigned in each case an arrangement of the rollers, and wherein the rollers of an arrangement with a helical wrap corresponding employment are aligned.
  • a band which alternatively comes from two oppositely directed inlet directions, can be easily deflected in each case by a deflection angle, for example by 90 °.
  • FIG. 1 schematically shows in a side view of an embodiment of a Bandumlenkvorraum 1. It consists essentially of a deflection cylinder 3 at the Circumferential surface line-wise rolling elements are arranged, which are designed as an employee rollers 20.
  • the band 2 initially runs from left to right, it strikes the deflection cylinder 3 at the top and leaves it on its underside.

  • FIG. 1 and FIG. 2 As shown device, it is possible to change the orientation of the belt 2, so that the incoming belt from the left 2 after leaving the Bandumlenkvortechnisch 1 enters the top down and at right angles to the inlet 14 into the next process stage.
  • the inlet direction 14 and the desired outlet direction 15 are predetermined by the topology of the individual treatment stations in a workshop. It may be the task to redirect an incoming according to the inlet 14 belt 2 at an angle and at the same time also to effect a reorientation of the band 2, that is to say a reversal of band top O and band bottom U. Another object may be to angularly deflect a band 2 entering in accordance with the inlet direction 14 without at the same time causing the band 2 to reorient itself. that is, the inlet-side strip surface also remains the outlet-side strip surface. In the latter case, another role is given in FIG. 3
