Definitions

  • ABSTRACT Method and apparatus for stacking knitted fabric issuing from a circular knitting machine in layers in a container by imparting reciprocal motion to the fabric so that it is folded in Concertina fashion.
  • the means for layering the fabric are in the form of a pair of rods or rollers driven by reversible or non-reversible drive means, said rods or rollers operating in a stationary horizontal plane, or being raised in increments with the stacked fabric.
  • This invention relates to circular knitting machines, and more particularly to a method of, and means for, automatically stacking knitted fabric in a container in continuation of the knitting thereof on large diameter circular knitting machines.
  • large diameter in this instance is meant machines having a knitting diameter of about inches and over.
  • the work take-off machanisms of large diameter circular knitting machines comprise a pair of co-acting work take-off which tension the fabric away from the needles, which are followed by a winding-up roller on which the fabric is wound as it issues from the take-off rollers.
  • a method of stacking knitted fabric, in layers, in a container in continuation of the knitting thereof which comprises continuously feeding the knitted fabric into the container and simultaneously causing the fabric to be folded, in concertina fashion, and in a uniform manner, over the width or the length of the container.
  • apparatus for stacking knitted fabric, in layers, in a container in continuation of the knitting thereof which comprises means for guiding the fabric issuing from the knitting machine in a to-and-fro motion whereby the fabric will be folded, in concertina fashion, and in a uniform manner, over the width or the length of the container.
  • Themeans for guiding the fabric may comprise mechanical guide members which are reciprocated over the width or length of the container. Such reciprocation may be effected by a reversible drive motor, or alternatively, by a non-reversible drive motor through an endless chain drive.
  • the means for guiding the fabric may comprise pneumatic means in the form of a jet or jets of air under pressure arranged adjacent two opposite sides of the container, means being provided to control the operation of the air jets so that the fabric is guided by the air from opposite sides alternately.
  • FIG. 1 is an end elevation, partly in section, showing one embodiment of the fabric layering apparatus according to the invention, and also showing certain parts of the knitting machine with which the apparatus is used,
  • FIG. 2 is a side elevation corresponding to FIG. 1 but showing only the essential parts of the apparatus
  • FIG. 3 is a part plan view corresponding to FIG. 2,
  • FIG. 4 is a detail, on an enlarged scale, of part of FIG.
  • FIG. 5 is a plan view of an alternative embodiment of the invention.
  • FIG. 6 is a side elevation corresponding to FIG. 5, certain parts of the apparatus being omitted,
  • FIG. 7 is a side elevation showing a modification of the embodiment of FIGS. 5 and 6,
  • FIGS. 8, 9 and 10 are details showing the mode of operation of the embodiment of FIG. 7,
  • FIG. 11 is a side elevation of a further modification of the embodiment of FIGS. 5 and 6, and
  • FIG. 12 is a schematic elevation of a further alternative embodiment of the invention.
  • FIGS. 1 to 4 of the drawings there is shown the lower part of a circular knitting machine 1 having supporting legs 2 to which a stationary base plate 3 is fixed. Mounted on the base plate 3, with an annular bearing 4 interposed is a rotary table 5 which supports the fabric tensioning and collecting equipment generally indicated by a pair of tensioning rollers 6 and supporting posts 7.
  • the tensioning rollers 6 are driven in well known manner in synchronism with the fabric output.
  • One such arrangement of fabric tensioning means is shown in our prior British Patent Specification No. 1,1 18,547.
  • other arrangements may be used such as a brush tensioning mechanism of the kind described in British Patent Specification No. 729920 of G. Lebocey or a spiked roller mechanism of the kind described in British Patent Specification No. 671477 of Mellor Bromley Limited.
  • the tensioning mechanisms are arranged in circular formation within the tubular fabric and, in order to adapt such arrangements for use with the layering apparatus of the present invention, it is only necessary to arrange two guide bars or rollers below the tensioning means to close the tubular fabric into a substantially flat form before it is fed to the layering apparatus.
  • the rotary table 5 also supports the layering apparatus of the invention which comprises generally a pair of fabric layering rollers 8 and 9', a pair of spaced support frames 10, and a fabric-receiving container 11 which is removably supported on support blocks 12 between the frames 10.
  • the fabric layering rollers 8 and 9 are supported and driven at each end thereof in exactly the same manner and therefore the following description will be with respect to one end only thereof.
  • the rollers 8 and 9 are mounted respectively on shaft 13 and 14 which are each provided with a freely rotatably roller 15.
  • the roller 15 are positioned to run over a guide surface 16 provided on the frame 10 to provide heightwise location for the rollers 8 and 9.
  • gear wheels 17, these gear wheels being fixed to the shafts and being adapted to engage a toothed rack 18 provided on the frame 10. In this respect, for the reason hereinafter described, the rack 18 does not extend over the full length of the container 1 1.
  • the gear wheels 17 each incorporate a one-way gear to known construction which includes a pawl and ratchet mechanism so that the gear wheel is positively driven in one direction only.
  • movement of the rollers 8 and 9, by means hereinafter described, in one direction is effective to cause one gear wheel 17 to positively rotate its co-acting roller, whereas movement of the rollers 8 and 9 in the opposite direction is effective to cause the other gear wheel 17 to positively rotate its co-acting roller.
  • the arrangement of the gear wheels 17 and their one-way gears is such that rotation of the roller 8 or the roller 9 is in a direction that, in use, causes the fabric to be fed in a downward direction, it being understood that the roller which is not being positively driven is free-wheeling and is rotated by the pressure applied thereto by the positively driven roller via the fabric.
  • a driving link 24 is connected between an endless drive chain 25 and the centre of the coupling link 20, the link 24 being formed with a slot 26 so that a pin 27, which secures it to the link 20, is slidable therein.
  • the chain 25 is continuously driven in one direction by means hereinafter described and is mounted for this purpose on end sprockets 28 and 29. It will be noted that, in the drawings, the rollers 8 and 9 are being moved from right and left and therefore positive drive is being applied to the roller 8 by its coacting gear wheel 17.
  • rollers 8 and 9 since rotation of the rollers is dependent upon movement thereof relative to the toothed rack 18, the rollers 8 and 9 will also stop rotating. However, to ensure proper layering of the fabric, it is preferably that the rollers 8 and 9 should continue to rotate during said pause in order that continued feeding of the fabric should take place.
  • the rack 18 stops short of the end of the frame 10 so that the gear wheels 17 move out of engagement with the rack.
  • a sprocket wheels 30 is mounted on the shaft 13 to enter into engagement with the drive chain 25.
  • the sprocket wheel 30 is of the same type as that of the gear wheels 17, i.e. it incorporates a one-way gear mechanism consisting of ratchet 31 and a pawl 32 so that it drives in one direction only.
  • the chain sprockets 28 and 29 are mounted on stub axles 33 and 34 fixed to brackets 35 provided on the frame 10.
  • a further sprocket wheel 36 is mounted on the stub axle 33 and is secured to the sprocket wheel 28 so that they rotate in unison.
  • a magnetic particle coupling 37 Arranged on the stationary base plate 3 is a magnetic particle coupling 37 of known construction.
  • the output shaft of the coupling 37 has fixed thereto a bevel gear 38 whilst the input shaft thereof is fixed to the stationary base plate 3.
  • the bevel gear 38 is in mesh with a bevel gear 39 fixed to a lay shaft 40.
  • the shaft 40 has fixed thereto a chain sprocket 41 and a drive chain 42 extends between the sprockets 36 and 41 to impart drive to the chain 25.
  • the coupling serves to apply a preset torque to the output shaft thereof and thus also to the bevel gear 38.
  • the lay shaft 40 is turning with the layering apparatus whilst the output shaft of the coupling 37, which is fixed to the base plate 3, remains stationary. This condition generates rotation of the shaft 40 due to the fact that the bevel gear 39 moves round the bevel gear 38 and this will drive the chains 42 and 25 at a speed corresponding to the output of the knitting machine.
  • potentiometer 43 Although only one potentiometer 43 has been described, it is possible to provide a plurality of potentiometers linked in parallel and all set at different levels, and switched into operation at pre-determined intervals, so as to provide different speeds of traverse, and therefore fabric consumption, of the rollers 8 and 9.
  • the fabric-receiving container 11 is positioned as shown in FIGS. 1 to 3 of the drawings and sufficient fabric F is knitted to be fed between the tensioning rollers 6 and the layering rollers 8 and 9 to reach the bottom of the container 11 where it may be fixed as by spring clips.
  • Knitting is then continued and the layering rollers 8 and 9 are reciprocated over the container 1 1 so that the knitted fabric will automatic-ally layer itself over the full length of the container 11.
  • the rate of feed of the fabric through the rollers 8 and 9 is nominally set by the gear and chain drive ratios and the speed of traverse, and the feed can then be further adjusted by the potentiometer 43 which controls the magnetic particle coupling 37.
  • the apparatus hereinbefore described may be modified for handling certain fabrics by providing means for positively holding each fold of the fabric in a position adjacent the end walls of the container 1 1.
  • Such means comprise a pair of dropper arms 44 which are pivotally mounted in extensions 45 of the brackets to hang freely, under their own weight, within the container 11.
  • the free ends of the arms 44 are preferably provided with means, such as rubber or nylon pads, to increase their gripping capabilities.
  • a cam plate 46 is positioned on the shafts l3 and 14 and has two cam surfaces 47, 48 which engage and lift the arms 44 respectively at the end of each stroke. To enable full movement of the cam plate 46 to take place without reducing the depth of the container 11, the latter is formed with slots 49 in its ends walls.
  • FIGS. 5 and 6 of the drawings there is shown a part of the framework of a rotating cylinder circular knitting machine having three legs 50, 51 and 52 one of which, as is usual with these machines, houses or supports a drive motor (not shown) and a main control mechanism.
  • the legs are stationary but work take-off rollers 53 and 54, and their supports 55 and 56, which also house the take-off roller drive mechanisms, are rotated in unison with the needle cylinder. This is accomplished by means of a work take-off carriage which is gear driven from the motor housed within leg 52.
  • the foregoing structure is known art and it is also known to use fabric receiving means, such as a container 57, to receive the fabric issuing from the take-off rollers 53 and 54.
  • the container 57 is open-sided and has only a base 58, a front 59 and a back 60.
  • the container 57 is removable and is slidably received within, and supported by, location brackets 61 provided on a rotary table 62 so that, in use, it is possible to slide receptacles on and off the table 62 when changing a full container for an empty one.
  • Rotatably supported on the table 62 adjacent the corners of the fabric container 57 are four vertically disposed square-section-thread screws 63 which are also rotatably located, at their upper ends, in brackets (not shown) mounted on a revolving frame member of the knitting machine positioned above the fabric take-off rollers 53 and 54.
  • Each screw 63 has mounted thereon, by means of a mating screw-threaded hole, a co-acting bracket 64.
  • the brackets 64 adjacent the back 60 of the container 57 support a drive shaft 65 on which are mounted, adjacent each bracket 64, sprocket wheels 66.
  • the remaining two brackets 64 each have mounted thereon freely rotatable sprocket wheels 67.
  • Extending between the sprocket wheels 66 and 67 on opposite sides of the container 57 are drive chains 68.
  • Centrally located on the drive shaft 65 is a reversible motor 69 which is attached to a bracket 70.
  • the bracket 70 is formed with a projection which fits into a mating slideway formed on an upright post 71 so that the motor is movable, in a vertical direction, relative to the post 71.
  • sprocket wheels 72 Fixedly mounted on the lower end of the screws 63 are sprocket wheels 72. Passing round all of these sprockets wheels is a chain 73 so that, when one sprocket wheel turns, and thereby turns it co-acting screw 63 to raise its co-acting bracket 65, all the other sprocket wheels turn and raise their co-acting brackets 64.
  • a star wheel 74 Fixedly mounted on one of the screws 63 below the sprocket 72 is a star wheel 74.
  • the star wheel 74 is turned, during rotation of the apparatus to carry out a knitting operation, by entering into contact with a cam 75 positioned on a stationary part of the machine, every time it passes said cam.
  • the cam 75 is spring-loaded into an operative position and pulled out of action by a cable or other means under the control of the main control mechanism of the machine.
  • a handle is removably mounted on the top of one of the screws 63.
  • Power is supplied to the reversible motor 69 from a slip ring 76 arranged on a stationary part of the machine through contacts 77, an extension 78 of which is arranged vertically in the post 71 so as always to be in contact with the leads of the motor 69.
  • the bars 79 and 80 are driven backwards and forwards, as the fabric is drawn through the take-off rollers 53 and 54, by the motor 69 which, as stated, is a reversible motor.
  • a suitable control mechanism is provided to reverse the direction of rotation of the motor after a predetermined number of rotations of the needle cylinder of the knitting machine has taken place.
  • the fabric guiding mechanism consisting of the bars 79 and 80 is raised manually to its highest position, just below the work take-off rollers 53, 54.
  • the container 57 is then placed in position on the location brackets 61 of the table 62.
  • the fabric indicated at F is then knitted until it is of sufficient length to extend through the work take-off rollers 53 and 54 and the guiding bars 79 and 80 down to a corner of the container 57.
  • the machine is then stopped and the end of the fabric is clipped into this corner by any suitable means such as detachable spring clips 81.
  • the fabric guiding mechanism is then lowered to a position just above the base 58 of the container 57.
  • Knitting is then recommenced and the motor 69 started in order to impart reciprocatory movement to the bars 79 and 80.
  • the fabric guiding mechanism is raised by the cam 75 and star wheel 74.
  • the motor and cam are operated in synchronism with the knitting machine output under the control of the main control mechanism of the machine.
  • the machine is stopped, either manually by the operator, or by virtue of an earthing circuit micro-switch 82 which is actuated by one of the brackets 64 as the latter reaches a predetermined height.
  • the fabric F is then cut leaving sufficient length to clamp into another fabric container for the next stacking cycle.
  • the filled container is then removed and replaced by an empty one.
  • the container 57 is supported clear of the platform 62 by the brackets 61 in order to enable a fork-lift type of handling means to be used to take off the full containers.
  • FIGS. 7 to 10 of the drawings show only details which differ from FIGS. 5 and 6.
  • the motor 69 is mounted in a similar manner to that already described and shown but is offset from the chain sprockets 66 adjacent the back wall 60 of the container and drives these through gears or pulleys 83 and 84 and belt 85.
  • a shaft 86 on which the pulley or sprocket 83 is mounted is driven by the motor 69 which is supported in the same manner as that shown in FIGS. 5 and 6.
  • the container 57 is extended so that its front 59 and back 60 extend beyond the sprockets 66.
  • the fabric folds are retained at the extreme ends of the container and are not pulled back by the bars 79 and 80 on their return movement.
  • the bars 79 and 80 could be replaced by freely rotatable rollers.
  • FIG. 11 a modification of the arrangement of FIGS. 5 and 6 is shown in FIG. 11 wherein a sensing device to sense the level of the fabric relative to the bars 79 and 80 may be provided. Such a device would relay command signals to the drive mechanisms of screws 63 or its equivalent to stop or drive.
  • a light beam sensing device such as photoelectric cell 87 may be fitted on one of the brackets 64 to co-act with a light source (not shown) fitted on the bracket 64 on the other side of container 57 at a position directly opposite photo-electric cell 87.
  • the circuit from the photo-electric cell to the screw drive mechanism would be such that, when the light beam is totally cut-off by the rising layers of fabric, the cam is operated to engage the star wheel 74 to raise the bars 79 and until the light beam is just above the level of the layered fabric.
