Definitions

  • the invention relates to a reel, in particular for sheet metal strips, with a drivable, hollow reel shaft in which an expanding mandrel shaft is held in a rotationally fixed but axially displaceable manner, and with radially adjustable expanding mandrel segments, each of which carries one of two interacting transmission keys, of which is connected to the one with the reel shaft, the other but with the expanding mandrel shaft in the axial direction.
  • the reel mandrel In order to ensure trouble-free winding on a reel, particularly with thin sheet metal strips, the reel mandrel must have a smooth, edgeless surface.
  • the reel mandrels are usually designed as expanding mandrels in order to enable the removal of a coiled sheet metal bundle or the attachment of a coil to be unwound in a simple manner, there are gaps for the expanded mandrel between the individual expanding mandrel segments, which are delimited by sharp edges. So that the impression of these edges on the first turns of the band is avoided, filler pieces are introduced into the gaps between the individual expanding mandrel segments which have a corresponding overlap should create passage from expanding mandrel segment to expanding mandrel segment.
  • these filler pieces are mounted radially displaceably in the expanding mandrel shaft and can be automatically moved radially outward into the resulting gap between the expanding mandrel segments when the expanding mandrel segments are spread out, so that when the full expanding mandrel diameter is reached there is a continuous surface for the reel mandrel.
  • a disadvantage of this design is that separate filler pieces must be provided, which are to be stored in the expanding mandrel shaft and which require their own drive, which not only considerably increases the design effort, but also weakens the expanding mandrel shaft accordingly, so that such a reel is not suitable for heavy loads Bundles can be used.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a reel of the type described in such a way that a simple, gap-free mandrel surface is obtained in the expanded mandrel position with simple construction means without additional filler pieces.
  • the invention solves this problem in that the mandrel segments alternate with the reel shaft and the expanding mandrel shaft are connected so as to be displaceable in the axial direction and are alternately widened and tapered with respect to their width in relation to the reel shaft and are tapered, the gear wedges held against a displacement by the reel shaft, which interact with the expanding mandrel segments axially entrained by the expanding mandrel shaft support the expanding mandrel shaft so that it can move axially.
  • the axial displacement of the expanding mandrel shaft required for actuating the spline gear relative to the hollow reel shaft also results in an axial displacement of the expanding mandrel segments relative to one another, which, because of their wedge-shaped design, are mutually opposed move that the wedge gap widening when the mandrel is spread out between every second expanding mandrel segment is filled by the wedge of the intermediate expanding mandrel segments inserted into this wedge gap.
  • a gap-free surface of the spreading mandrel can thus be achieved without additional intermediate pieces.
  • the gear wedges which are held by the reel shaft against displacement with the expanding mandrel shaft and which cooperate with the axially displaceable expanding mandrel segments, must of course be axially displaceably supported on the expanding mandrel shaft in order on the one hand to exert a corresponding compressive force on the expanding mandrel segments and on the other hand to enable a relative movement between the gear wedges .
  • the expanding mandrel 1 of the reel shown consists essentially of an expanding mandrel shaft 2 and expanding mandrel segments 3 and 4 supported thereon by means of a wedge gear, the expanding mandrel shaft 2 being axially displaceable but non-rotatably in a hollow reel shaft 5 for actuating the wedge gear is stored.
  • a tongue and groove connection or a multi-slot connection is provided between the expanding mandrel shaft 2 and the reel shaft drivably mounted in a housing 6, but this is not shown in the drawing for the sake of clarity.
  • a head piece 7 which is screwed onto the end face of the expanding mandrel shaft 2 and is suitable for receiving a support bearing ring and which forms a guide recess 8 between itself and the expanding mandrel shaft 2 for a corresponding radial web 9 of the expanding mandrel segments 4.
  • These guide recesses 8 fix the expanding mandrel segments 4 in the axial direction, but not in the radial direction, so that the spreading movement is not hindered.
  • the respective expansion mandrel segments 3 lying between the expanding mandrel segments 4 are connected in a conventional manner with the aid of a flange 11 that overlaps them with respect to radial guide webs 10 and is axially displaceably connected to the reel shaft 5, which results in an exclusively radial movement of the expanding mandrel segments 3 when the expanding mandrel shaft 2 is axially displaced Due to the interacting gear wedges 12 and 13 designed in the form of step wedges, which are fixedly connected to the expanding segments 3 and the expanding mandrel shaft 2.
  • the lower half of the picture shows the expanding mandrel 1 in the contracted position in which the expanding mandrel segments 4 appear to be pushed out relative to the expanding mandrel segments 3.
  • the other, upper half of the figure shows the expanded state, which is characterized by the expansion mandrel segments 4 being pushed into one another.
