Definitions

  • the invention relates to a winding shaft with a multiplicity of self-tensioning individual winding bodies for winding cores which are rotatably and drivably mounted on it, a resilient tensioning device being inserted into an annular groove of each individual winding body, the outer diameter of which is larger than the inner diameter of the winding cores, the resilience of the tensioning device being a sliding one Postponing the winding cores in the axial direction allows by the tensioning device contains flexible spring elements in the radial direction and consists of segments whose end faces are chamfered and are arranged radially displaceably on intermediate pieces provided with a similar chamfer angle and connected to the bottom of the annular groove.
  • the winding shafts each accommodate a large number of winding cores. Fitting the shafts with winding cores is problematic because the numerous wound cores should be pulled off the winding shaft very quickly and replaced with empty winding cores in the correct position.
  • the tensioning device should not hinder easy and trouble-free displacement of the winding cores on the shaft when loading. Therefore, there are already numerous tensioning devices on the winding shaft, such as tilting chips, tensioning rollers, tensioning pins or the like. These tensioners represent mechanically complex constructions that drive up the costs of the winding shaft. The difficulties become all the greater if single winding bodies with separate friction are used.
  • a clamping device which consists of a rotatably mounted block seated on a circular disc, which contains two opposing bushings as clamping elements, each of which is spring-supported
  • Have balls and the tensioning elements are located at a distance from the circular disk, so that when pushed onto the block the winding core rests on one side against the circular disk and is arranged in the correct position on the other side by the tensioning elements.
  • DE-A-22 41 783 describes a tensioning device in which tensioning prisms are arranged on both sides of a winding core along a regular polygon lying parallel to the base surface of the winding core and which are each rotatable about the prism edge.
  • DE-A-10 50 964 relates to a winding sleeve for pushing on a winding tube, consisting of a one-piece solid core, into which dovetail-shaped slots are milled distributed over the circumference and extending in the axial direction. These contain axially insertable, correspondingly shaped, radially displaceable segments, which are biased by axially extending leaf springs arranged between the core and the segment, and the force transmission between segments and winding tube is supported by centrifugal force.
  • FIGS 1 and 2 show a preferred embodiment of the present invention.
  • the torque transmission between the winding shaft and individual winding bodies can take place via an eddy current clutch, friction clutch, which is loaded, for example, with compressed air or a somehow braced bearing, is not the subject of this invention.
  • a plurality of cylindrical segments (2) are arranged in the annular groove, the two end faces (13) of which are chamfered.
  • the segments described are anchored by intermediate pieces (3) which are mushroom-shaped in cross section and which are attached between two segments to the bottom of the annular groove and are correspondingly bevelled in the opposite way to the end faces (13) of the segments.
  • a leaf spring (4) is inserted as a spring element, which is supported with its two free ends at the end of the segment and with its central part on the bottom of the annular groove.
  • the dimensions of the leaf spring determine the clamping force of the clamping element.
  • the outer surface of the segments (2) protrudes slightly beyond the peripheral surface (5) of the single winding body (6).
  • the intermediate parts (3) limit the radial spring travel of the segments (2) to the outside.
  • the intermediate parts (3) prevent rotation of the segments (2) in the circumferential direction by the torque transmission from the individual winding body (6) to the winding core (9).
  • each segment has an annular bead (10) on both sides of its outer surface, the distances between the two annular beads being the width of the winding core correspond.
  • FIGS. 3 and 4 Another preferred version is shown in FIGS. 3 and 4, respectively.
  • four spring elements (18) are provided per segment, consisting of coil springs (15) which are inserted in sleeves (16) which are in the bottom of the annular groove (14) and bear ball thrust pieces (17) at their free end, which counteract press the inside of the segments (2).
  • Two spring elements described in this way are arranged on both sides of both ends of the segment.
  • the leaf spring (4 ') can be provided with an opening in its central part and is fastened to the intermediate piece (3) on the bottom of the annular groove, while its two free ends on the inside of two adjacent segments ( 2), the next leaf spring (4 '') and so on.
  • the bead (10) can only be arranged on an outside of the segment (2), while a spring-loaded ball thrust piece (10 ') is arranged on the opposite side and in this way represents a snap-in or centering device for the winding core (9).
  • FIG. 7 Another variant can be seen from FIG. 7.
  • the winding core is brought to a stop on a bead (10); the ball thrust piece (10 '') is attached this time to the intermediate piece (3) lying between the segments (2).
  • Suitable as winding cores are the so-called NAB cores or winding cores according to DE 24 48 853, which have axial deformations on both sides, which protect stacked cores against shifting or twisting.
  • a 65 cm wide plastic carrier web with a magnetic coating is cut into approximately 50 strips each 1.27 cm (1/2 ") wide and the strips alternately on two complete tensioning devices at a speed of up to 500 m / min., so that on each winding shaft 25 reels up to a length of 5,000 meters were wound on each winding core, which gives a total weight of the reels of 50 kg on each winding shaft Winding pattern.
