Definitions

  • This invention relates to carding engines having a main carding cylinder, side plates one to each side of the carding cylinder, each side plate carrying an adjustable bend assembly providing a bearing surface, and a plurality of flats mounted to travel on, and to be supported by, the bearing surface.
  • the objective of the present invention is to provide a bend construction that will facilitate both accurate and close settings in a carding engine as aforesaid, and will allow removal of subjective factors in achieving those settings.
  • a conventional bend construction for a carding engine having travelling flats comprises a fixed bend supported from the frame of the carding engine together with a flexible bend mounted on the fixed bend, the flexible bend having an outer circumferential surface that forms the bearing surface on which the ends of the flats run.
  • the fixed bend and flexible bend are notionally concentric with the main carding cylinder, and the flexible bend is radially adjustable with respect to the fixed bend at a number of angularly spaced points around the flexible bend.
  • the flexible bend can be adjusted to achieve a degree of concentricity.
  • a carding engine having a main carding cylinder and side plates one to each side of the carding cylinder, each side plate carrying an adjustable bend assembly providing a bearing surface; and a plurality of flats mounted to travel on, and to be supported by, the bearing surface characterised in that the bend assembly comprises a plurality of separate, circumferentially adjacent arcuate segments each having a radially outer surface that constitutes part of the bearing surface, an end of the radially outer surface of each segment lying adjacent to an end of the radially outer surface of a next adjacent segment, and means mounting each segment on its associated side plate so as to be adjustable relative to that side plate in a direction generally radially of the cylinder.
  • each segment two adjustable mounting means are provided, and are angularly spaced apart adjacent to respective ends of the segment.
  • each mounting means comprises support means secured to the side plate and having an arcuate radially outwardly facing surface that is substantially concentric with the surface of the carding cylinder, means for adjusting the spacing between a radially inwardly facing surface of the segment and the radially outwardly facing surface of the support means and means for securing the segment to the support means with the required spacing therebetween.
  • the support means may be a continuous arcuate member secured to the side plate and extending at least the full annular extent of all the segments.
  • the support means may comprise one or more separate support blocks for each individual segment.
  • the preferred adjusting means comprises shims between the radially inwardly facing surface of the segment and the radially outwardly facing surface of the support means.
  • the use of shims gives particular advantage as will be explained in more detail hereinafter, and allows segments to be re-set to new spacings both rapidly and with a high degree of accuracy.
  • the adjusting means may comprise any suitable type of screw- threaded adjuster, for example a filbow arrangement.
  • Radially outward adjustment of the segments to provide a bearing surface of greater radius also has the effect of widening gaps between the confronting ends of adjacent segments. To a degree, such gaps can be tolerated without significantly affecting the movement of the flats over the bearing surfaces.
  • the radial outward movement of the segments combines with some slight circumferential movement of the segments it is possible that segments can bunch together in one region of the bend construction, so leaving quite a large gap between adjacent segments in another region of the bend. Restraint on the movement of certain of the segments can reduce this problem and conveniently at least a centre one of the segments is constrained against any circumferential movement relative to the side plate.
  • At least one of the end segments may be constrained to move relative to the side plate only in a direction parallel to the plane of that end face of the segment which confronts the end face of the next adjacent segment.
  • Figures 1 to 3 show part of a carding engine comprising a main cylinder 1 having carding elements 2 on its outer surface.
  • the cylinder is hollow and is supported by a conventional spider 3 on a suitable bearing assembly at each side of the cylinder.
  • a fixed side plate 4 is secured to the frame 5 of the carding engine. It will be understood that the construction at each side of the carding cylinder is identical, except for being of opposite hand, and accordingly only one side is to be described.
  • the side plate 4 has welded thereto a continuous arcuate support member 6 having a radially outwardly facing surface 7 that is concentric with the surface of the carding cylinder.
  • a total of five bend segments 8 to 12 are supported on the support member 6.
  • Each segment has a radially inwardly facing surface 13 and a radially outwardly facing surface 14 which forms a bearing surface for the support of bearing members on flats supported by and travelling on the bends.
  • the bearing members of the flats are rollers 15 rotatably mounted on spindles 16a supported by end assemblies 16b of the flats 18.
  • flats may be supported by end members which slide on the bearing surfaces.
  • the profile of the bearing surface is, of course, shaped to accommodate and support whatever support arrangement the particular flats are provided with.
  • Each of the segments is adjustable relative to the side plate 4 in a direction generally radially of the cylinder, and for this purpose adjusting means are provided adjacent to each end of each segment.
  • the adjusting means comprises shims 16 between the radially inwardly facing surface 13 of the segment and the radially outwardly facing surface 7 of the support member 6. Additionally, a bolt 17 passes through a bore in the support member 6 and engages a tapped bore 17a on the segment. As will be described in more detail later, use of appropriate thickness of shims 16 enables proper adjustment of each segment on the side plate. Once appropriate shims are in place the bolt 17 is tightened to clamp the segment to the support member 6.
  • Each segment is also formed with an enlarged hole 19 through which a bolt 20 passes to engage a tapped bore 20a in the side plate 4, so additionally securing the segment to the side plate in a direction extending axially of the cylinder.
  • the centre segment 10 is formed with a radially extending groove 21 in that surface which faces towards the side plate 4 and a peg 22 secured to and extending from the side plate engages in the groove.
  • the segment 10 is thus constrained to move in a true radial direction during its adjustment, and circumferential movement relative to the side plate 4 is prevented. Movement of the two end segments 8 and 12 is also constrained by the presence of respective stop plates 22, 23 which are pinned or welded in position on the side plate 4.
  • An abutment surface 24 of the stop plate 22 confronts an abutment surface 25 of the segment, surfaces 24 and 25 lying in planes which are parallel to the plane of the end face 26 of the segment which confronts the end face of the next adjacent segment 9.
  • the segment 8 is thus constrained to move in a direction parallel to those planes.
  • confronting surfaces 27 of the stop plate 23 and 28 of the segment 12 are coplanar with the end face 29 of the segment 12 which confronts the next adjacent segment 11.
  • Rigid pads 34 extend downwardly from the bar towards each end thereof and are designed to lie on the tips of the carding elements 2. At each end of the bar there is a micrometer screw arrangement 35 having a tip 36 designed to engage the bearing surface 14 of the appropriate segment such as 10.
  • the base setting of each segment is effected in turn.
  • the setting tool is placed so that the pads 34 bear on the tips of the cylinder wires with the bar 33 extending axially of the cylinder and with the tips of the micrometer screws 35 lying generally in the same radial plane as the bolts 17 at the appropriate ends of the respective segments at each side of the carding engine.
  • a base shim 16 is then selected and inserted between the segment and support member 6, the shim thickness being such as to cause contact between the tip of the screw 35 and the bearing surface 14.
  • FIG. 4 show part of a carding engine having a main carding cylinder 101 furnished with carding elements 102.
  • the carding cylinder is supported by bearings on a frame from which side plates 103 extend at each side of the cylinder.
  • Each side plate 103 carries an adjustable bend assembly comprising a plurality of arcuate segments 108, all of which are similar in their construction and associated components.
  • Each segment has a radially outer bearing surface 109 for supporting the ends of the flats during their travel around the carding cylinder.
  • Each segment 108 has two support blocks 110 and 111 contacting the inner surface of the segment at angularly spaced locations.
  • Each support block is radially adjustable on the side plate 103 and can be secured thereto by way of bolts 112, 113 and 114, 115 respectively, the bolts passing through oversize holes in the blocks to allow the required adjustment and engaging in tapped holes in the side plate 103.
  • Each block also carries an adjusting bolt 116, 117 passing through the block and engaging into a tapped bore in the radially inner surface of the segment 108.
  • Segment 108 is further secured to the side plate at two angularly spaced locations by two bolts 118, 119 passing through oversize holes in the segment and into tapped bores in the side plate 103.
  • the segments can be set so that their radially outer bearing surfaces abut to form a substantially continuous track around the relevant arc of the carding machine, the track being substantially concentric with the main carding cylinder.
  • To set each segment the following procedure is adopted.
  • the segments and bearing blocks are bolted loosely to the side plate, and the adjusting bolts 116, 117 bolted loosely through the bearing blocks into the segments.
  • a setting plate 120 is then bolted at angularly spaced positions by bolts such as 121 to the bearing surface of the segment, to overlie and rest on the tips of the carding elements on the main cylinder as shown in Figure 5.
  • the insertion of shims between the segments and the support means may change the relationship between the bearing surface and main cylinder from a condition wherein the bearing surface is exactly concentric with the envelope of the tips of the carding elements on the main cylinder. Radially outward or inward movement of the segments due to the shim changes will remove the concentricity from this relationship.
  • the spacing between the bearing surface and that envelope will vary around the arc of the bearing surface from a maximum value at the centre of the bearing surface to a minimum value at each end of the bearing surface.
  • each segment at its centre is no more than 70° and if the percentage difference (if any) between the radius of the bearing surface and the radius of the envelope of the tips of the carding elements is no more than 0.05% then the clearance differences are so small that they can be ignored, even when it is desired to run the carding engine with very small settings, of the order of 0,1mm (seven thousandths of an inch) or less, between the carding elements on the flats and those on the main cylinder.
  • the subtended angle of the segment is of course not limited to a maximum of 70°, and segments of greater extent may be used, still achieving settings that are closer and more accurate than those hitherto achieved.
  • bend constructions utilising a number of segments differing from those particularly described may be made, and similarly there are other methods of providing the necessary supporting elements for the bend segments and of adjustably mounting the bend segments on those support elements.
  • the cooperation between the flats and the bend segments has been described with respect to the conventional arrangement wherein the flats move over the bearing surfaces of the bends.
