Definitions

  • the present invention is concerned with a servicing attachment for occasional use on a carding machine, which includes a rotary device which co-operates with a roller of the machine to improve the performance of that roller.
  • a servicing attachment is a grinder for grinding the teeth of card-clothing on the roller, and another is a fettler, which has a rotary brush or comb for removing fibrous waste and other foreign matter from the card-clothing on the roller.
  • One well known grinding attachment of this kind employs a grinding wheel, supported on a short sleeve, which is mounted for rotation on a carrier sleeve extending across the width of the machine, the carrier sleeve being slotted through most of its length, and the short grinding wheel sleeve having an internally projecting peg passing through the slot in the longitudinally extending sleeve, into an endless reversed helical groove in a spindle which passes through the longitudinal sleeve and is coaxial therewith.
  • Both the spindle and the longitudinal sleeve are rotated about their common axis by a driving motor mounted at one end of the grinding attachment, but the driving mechanism is such that there is a differential between the angular velocity of the sleeve, and that of the spindle, so that the grinding wheel is caused to have a reciprocating traverse along the longitudinal sleeve, in addition to its own rotation.
  • the peripheral speed of the grinding wheel is restricted to a speed lower than that which is desirable for grinding card-clothing - particularly metallic wire card-clothing - because of the mechanical limitations of safely rotating the slotted tube carrying the considerable mass of the traversing grinding head.
  • the maximum safe working speed of the grinding wheel is 900 r.p.m., and with a three inch diameter tube, this falls to 750 r.p.m.
  • these speeds are low for grinding, so that the grinding wheel tends to wipe rather than cut the metal being ground.
  • it is difficult to change the grinding wheel because one has to dismantle the assembly of the grinding wheel sleeve, longitudinal sleeve and spindle.
  • a servicing attachment for use on a carding machine of the type which has a rotary device for co-operation with a roller of the machine said servicing attachment having a longitudinally extending support structure and a traversing unit which unit itself comprises: a carriage, a spindle for the rotary device mounted on said carriage, and a driving motor for the rotary device also mounted on said carriage, and means mounting said traversing unit for longitudinal reciprocation on said support structure is characterised in that an arm projects laterally from each end of the support structure, there being a stub axle carried by each said arm for locating the attachment in bearings on a carding machine, with a gap between the stub axles within which the spindle can traverse during the longitudinal reciprocation of the traversing unit, so that no part of the support structure passes through the spindle.
  • the diameter of the spindle can be of the same order as would be employed in an ordinary grinding machine, and hence a relatively large radial thickness of the grinding wheel is available for useful work.
  • the change can be effected quite simply.
  • the provision of the stub axles allows the attachment to be mounted in bearings on the carding machine frame.
  • the two stub axles are substantially coaxial with the spindle, whereby when said stub axles are located in bearings on a carding machine, adjacent to a roller to be serviced, there is a range of angles about the axis of said spindle at which the attachment can , be orientated without substantially altering the setting between the rotary device and the roller to be serviced. This arrangement minimizes the problem created by the confined space available for the attachment.
  • a subsidiary object of the invention is to provide an improved grinding attachment for use on a carding machine, which has a relatively high degree of accuracy of grinding wheel location during the grinding operation.
  • a grinding attachment for use on a carding machine comprises a longitudinally extending beam and a traversing unit adapted to reciprocate longitudinally on the beam, the traversing unit comprising: a saddle mounting a grinding wheel spindle disposed on one side of said beam and a driving motor for the grinding wheel spindle disposed on the opposite side of said beam to said grinding wheel spindle, there being an endless flexible drive member connecting said motor to said spindle, said flexible drive member having runs extending on opposite sides of said beam, and is characterised in that at least two laterally spaced precision locating and load bearing guide tracks are secured to a face of the beam and the traversing unit has bearings engaging on said guide tracks permitting longitudinal sliding of the traversing unit on the beam, so that the traversing unit is entirely supported in respect of its own weight and any applied loads through the beam, an arm projecting laterally from each end of the beam, and there being a stub axle carried by each said arm with a gap between the stub axles within which the spindle can traverse during the longitudinal
  • This arrangement ensures a maximum resistance to deflection of the traversing unit when under load despite the absence of any part of the support structure passing through the grinding wheel spindle.
  • a maximum expected deflection in the order of 0.025 millimetres (0.001 inches) would be acceptable.
  • a steel beam 10 of hollow square cross- sectional extends longitudinally of the attachment, and is of substantial proportions, as it is intended to carry all the applied loads, without deflection of a magnitude to significantly affect the grinding operation.
  • the length of the beam 10 is determined by the width of the carding machines on which the grinding attachment is to be used, since the beam 10 must be of approximately the same length as the width of the principal card-clothed roller on the carding machine itself.
  • Boxes 11 and 12 of slightly larger cross-section than the beam 10, are secured to opposite ends of the beam, these boxes providing housings for pulleys (not shown) which are used in a traversing mechanism which will hereinafter be described in detail, the box 1.1 also supporting a small electric motor 14, hereinafter referred to as a traversing motor, and the box 12 carrying a control panel 16.
  • An arm 18 projects fcrwardly from each of the boxes 11 and 12, there being a tubular stub axle 20 located in each of the arms 18, these stub axles being coaxial with each other.
  • each stub axle 20 projects inwardly from its respective arm 18, and at its inner end, the stub axle is formed with a part spherical seating 22, for reception in a mounting bracket on the carding machine as will be hereinafter described. Between the part spherical seating 22 and the inside face of the arm 18, a knurled nut 24 is fitted on to a screw-threaded portion of the axle 20.
  • An end plate 26 is secured to and closes the otherwise open end of each of the boxes 11 and 12, and each of these end plates 26 has a rearwardly projecting flange 28, which provides a mounting for a tubular handle 30, which extends outwardly from the plate 26.
  • the stub axles 20 extend outwardly from their respective arms 18, and there is thus provided a pair of handles 20 and 30, at each end of the grinding attachment, by means of which it is possible to manipulate the attachment when fitting it on to or removing it from the carding machine.
  • a traversing unit 32 is adapted to reciprocate along the length of the beam 10, between the end boxes 11 and 12, and this unit has a cast metal saddle 34, which includes a short square tubular section 36 (see Figure 3) which embraces the beam 10, the internal dimensions of the short tubular section 36 being somewhat larger than the external dimensions of the beam 10, so that the saddle 34 is quite free to move endwise on the beam.
  • the saddle 34 also has a forwardly extending flange 38 which provides support for a grinding wheel spindle mounting 40, and there is a rearwardly extending flange 42, which provides a mounting for an electric motor 44, hereinafter referred to as the grinding wheel motor.
  • a pair of guide tracks are provided by cylindrical rods 46 and 48 (see Figure 2) which are secured to the front face of the beam 10.
  • a mounting strip 50 Near to the upper front edge of the beam 10, there is a mounting strip 50, which is welded to the beam and which extends longitudinally thereof.
  • the front face of the strip 50 is concave in cross-section as illustrated in Figure 2 - although it could be of V shape - and the top guide rod 46 is received within the concave front face of the mounting strip 50.
  • Clearance holes are formed through the front plate of the beam 10, and the strip 50, at spaced apart positions along the length of the beam, and a set-screw 52 passes through each of these holes and engages in a screw-threaded hole in the rod 46.
  • the guide rod 46 is firmly anchored to the beam 10.
  • the front face of the strip is flat (i.e. parallel with the front face of the beam 10), and a corresponding flat is formed on the lower guide rod 48.
  • Recirculating ball-bearings 58 and 60 are mounted on the saddle 34, and are engageable respectively on the guide rods 46 and 48.
  • Each of the recirculating bearings has a cut-away portion to pass over the respective mounting strip 50 or 54 (see Figure 2) and is therefore of "C" cross-section.
  • Recirculating ball-bearings are well known in themselves, and need not be described in detail. However, for present purposes, it will be noted that these bearings provide a very firm location of the saddle 34, and therefore the entire traversing unit 32 on the guide rods 46 and 48, and the latter are of course themselves firmly supported by the beam 10. Since there is a clearance between the beam 10, and the tubular portion 36 of the saddle 34, the latter is supported entirely by the guide rods 46 and 48.
  • the grinding motor 44 has an output shaft 62, which passes through the flange 42, and a driving pulley 64 is keyed on to the shaft 62, for rotation therewith.
  • the grinding wheel mounting 40 includes a bearing housing 66, carried by the forwardly extending flange 38 of the saddle, and an assembly of two ball or roller bearings 68 and 70 within the housing 66, provides a journal mounting for a grinding wheel spindle 72. The latter extends on the same side of the flange 38 as the tubular portion 36, and is provided with a conventional pair of grinding wheel clamping members 74 and 76.
  • a grinding wheel cover 82 is secured to forward extensions on the tubular portion 36 of the saddle by knurled screws 84, and of course this cover 82 must be removed before it is possible to change the grinding wheel 78.
  • the grinding wheel spindle 72 being of the normal solid construction, is of a relatively small diameter, and since this is the only part which passes through the centre of the grinding wheel, it is possible to have a relatively large radial thickness of the grinding wheel which is available for use.
  • the radial dimension of the grinding wheel which is capable of being worn away whilst still retaining the effectiveness of the wheel is indicated at "X" in Figure 3.
  • a driven pulley 86 is secured to the grinding wheel spindle 72 by means of a setscrew 88, this pulley being arranged on the opposite side of the flange 38 to the grinding wheel 78, and in alignment with the driving pulley 64 on the grinding wheel motor 44.
  • An endless belt 90 connects the two pulleys 64 and 86, for the purpose of transmitting driving motion from the motor 44 to the grinding wheel 78.
  • the saddle 34 has an outturned flange 92, which effectively provides a housing for the belt drive, there being a plate-like cover 94 for this housing.
  • the driving pulley 64 is of slightly larger outside diameter than the depth of the beam 10
  • the pulley 86 is considerably smaller in diameter than the depth of the beam 10
  • a pair of additional guide rollers 96 and 98 is provided.
  • Each of these follers is mounted on a pair of ball bearings 100 (see Figure 4) and these in turn are mounted on a bush 102 which is screw-threaded internally, to receive a set- screw 104.
  • the latter passes through a vertical slot 106 or 108 in the flange 38, and this provides a means of adjusting the vertical position of the guide pulley 96 or 98 as the case may be.
  • each roller bearing may be mounted on an eccentric pin so that by rotating the pin it is possible to obtain the required vertical adjustment of the roller 96 or 98.
  • the pulley 64 will be of the same outside diameter as the pulley 86, and it will then be necessary to provide an additional pair of guide rollers similar to the rollers 96 and 98, but arranged on the flange 42, at the motor side of the beam 10.
  • the box 11 there is a speed reduction gear fastened to the output end of the traversing motor 14, and the traversing pulley (previously referred to but not shown) at that end of the apparatus is keyed on to the output shaft of the speed reduction gear.
  • the other traversing pulley which is housed within the box 12 is mounted on a bracket (not shown) which is capable of sliding motion on a longitudinal direction within the box 12, there being a screw having a knurled head 110 ( Figures 1 and 5) for producing sliding movement of the mounting bracket. In this way, it is possible to move the pulley in the box 12 towards and away from the pulley in the box 11.
  • a cable 112 is anchored at one end to the traversing unit 32, passes from there twice round the pulley in the box 11, to give a capstan effect, returns along a path adjacent to the bottom of the beam 10, through clearance holes in the carriage 34, passes around the pulley in the box 12, and then returns along the top to the carriage 34 to which its other end is anchored.
  • the traversing mechanism can be operated, and if the motor 14 is started, it turns the pulley in the box 11, and this pulls the traversing unit 32 through the cable 112 towards the box 11.
  • a proximity switch 114 is mounted in the beam 10 adjacent to the box 11, and when the traversing unit 32 arrives at the box 11 end of its travel, where the grinding wheel 78 would be moving off the end of the card-clothing on the carding machine roller, the proximity switch is actuated by an adjustable actuating plate mounted on the traversing unit, and this causes reversal of the traversing motor 14, so that the unit 32 begins to move in the opposite direction towards the box 12.
  • a similar proximity switch 116 is mounted in the beam at the other end, and when the unit 32 arrives at that end of the beam, the switch 116 is activated and this also reverses the motor 14, causing the unit 32 to travel again towards the box 11. In this way, so long as the apparatus is operational, the unit 32 will be reciprocated along the length of the beam 10. It is possible to vary the stroke length by adjusting the position of the actuating plates.
  • a carding machine cylinder is indicated at 120, and a doffer at 122.
  • Brackets such as those shown at 124 and 126 are provided on the machine frame to receive the grinding attachment. It will be appreciated that the brackets are always provided in pairs arranged one at each side of the machine, so that the grinding attachment can be mounted between the pair of brackets.
  • Each bracket has an open-topped bearing (indicated diagrammatically at 128 and 130 in Figure 8) within which the axle of the grinding attachment is received.
  • the part spherical seatinqs 22 are located in the brackets 124, and then the knurled nuts are screwed inwardly, until they press tightly against the outside faces of their respective mounting brackets 124, thereby locating the grinding attachment laterally with respect to the carding machine. It is of course possible to adjust the lateral displacement of the grinding attachment, by slackening one of the nuts 24, and tightening the other.
  • a stay is provided at each side of the machine, this stay comprising a bar 132 having a hole 134 at each end to receive a pin by which the stay can be connected to one of the end plates 26 of the attachment, and an elongated slot 136 in which is fitted a clamp screw 138 having a cylindrical part which is adapted to fit in one of the bearings 128 and 130 in the brackets 124 and 126 on the carding machine.
  • each stay When the attachment has been located with its seatings 22 in the brackets 124, one end of each stay is coupled to one end of the attachment by a pin fitted through one of its holes 134 and the clamp screw is adjusted until it seats in the bracket 126 on the machine, at which stage the clamp screw is tightened.
  • the part of the stay between the clamp screw and the attachment then provides a strut supporting the attachment against the gravitational load due to its own weight and forces tending to rotate the attachment when it is in use. It will be appreciated that the angle of inclination of the attachment is adjusted by adjusting the stay with respect to the clamp screw as permitted by the slot 136.
  • the mounting brackets 124 are then adjusted to bring the grinding wheel 78 into contact with the card-clothing wire on the cylinder 120.
  • the angular disposition of the grinding attachment relatively to the carding roller is immaterial, because even if the angular position is changed, this will have no effect on the contact of the grinding wheel 78 with the card-clothing.
  • the reason for this is that the stub axles 20 are coaxial with the grinding wheel itself and therefore any angular adjustment of the apparatus is about the axis of the grinding wheel spindle.
  • the facility for varying the angle is important, because it permits the grinding attachment to be fitted in the restricted space available on the carding machine.
  • the seatings 22 are located in the bearings 130 of the brackets 126.
  • One end of the stay is fitted on to the attachment and the clamp screw bearing surface is received in the bracket 124.
  • the stay 132 acts as a tie and the position of the attachment is shown in chain- dotted lines in Figure 8.
  • the ends of the beam may be supported on the said side frames of the carding machine.
  • flat bearing surfaces may be machined on the undersides of the boxes 11 and 12, or on the undersides of special brackets (not shown) attached to the boxes 11 and 12.
