Definitions

  • This invention relates to a ring spinning and twisitng machine.
  • Ring spinning and twisting machines are used for the production of short staple or long staple from roving or from sliver.
  • Conventional ring spinning machine has a plurality of spindles mounted on a ring frame and the yarn produced is wound on bobbins provided on these spindles.
  • the spindle is allowed to run initially at a slower speed for a predetermined period of time depending on the length of the yarn that is being processed. The speed is varied after the desired package content is obtained.
  • the main drive is translated to the spindle through a variating means.
  • This variator means has top and bottom pulleys connected by a 'V' shaped belt driving medium.
  • the top pulley is made up of two separate discs with adjustable means for reducing or increasing the distance between the two discs. This reduction or increase of distance between the discs results in the up or down movement of the V belt, thereby effecting a change in the driving diameter of the top and bottom pulleys causing speed variation.
  • the rotational diameter of the top pulley increases and that of the bottom pulley decreases thereby causing an increase in the speed of the bottom pulley.
  • Preconditioning involves time and loss of production due to consequential and unavoidable down timing of the machine.
  • the step of ring changing involves a number of operations that require preliminary work.
  • the drive to the drafting system must be disengaged, the drive to the ring rail must be disengaged, power supply to the relevant machine parts must be stopped, the ring rail must be raised to the desired position, and the spindle speed must be regulated.
  • the operator has to rotate the lappet assembly manually during these operations. After completion of the process of ring centering, these sequence has to be repeated and the machine reset to the desired starting position before commencing spinning operations. Manual operation of these sequences increase the downtime of the machinery leading to production losses.
  • the present system is also labour intensive in nature.
  • doffing cycle involves removal of full cops from spindles and placement of empty cops thereon for the next cycle of operation.
  • Automatic doffing has now become common in modern textile industry. Sequence of preliminary operations required for automatic doffing are transporting the full cops removed from the spindle to the next stage of operation, bringing in the empty cops and keeping empty cops at an intermediate location for replacement.
  • top arms locking and loading are effected by a thumb means which is pneumatically actuated.
  • Loading and locking means in the known top arm arrangement consists of a thumb actuated by pneumatic means having a cam joint to the handle of the top arm. The thumb transmits its load to the handle and when the handle is locked with the top arm, the load is transmitted to the top arm for pressing the top arm rollers against the corresponding bottom rollers.
  • the top arm and the thumb are fulcrumed on a fixed bracket to enable the above loading.
  • DLC diamond like carbon
  • the ring may have an ovality of 0.1mm, roundness of 90 microns and surface roughness of Ra 0.05 and hardness of 750 to 2000 HV.
  • the width of the flange may be atleast 3.2 mm + 0.05- 0 mm and base flatness is 0.01 mm.
  • Hydrogenated carbon film coating has a thickness of 2 to 3 microns and hardness of 2000 Wmk-2.
  • the traveller also may be coated with the DLC using the same plasma coating process.
  • the coating on the traveller may preferably have a thickness of 1 to 2 microns and hardness of 1000 to 1500 KV.
  • Speed variation system which is oontrolled, programmed and net worked has been developed to overcome the aforementioned drawbacks of the existing system.
  • the control and program means create automatically smooth speed curve and convert them into pulses for actuating conventional speed regulating means,thereby avoiding abrupt change in speed and hunting associated with conventional systems.
  • the speed variation system for textile machines comprises variator means, control means, programme means and valve means, wherein said control means is capable of measuring and storing spindle speed of said textile machine, said programme means is capable of generating smooth speed pulse signals from the speed data supplied thereto, by said control means to actuate the valve means through pulse train for regulating said variator.
  • the variator may be pneumatic variators known conventionally in the art having two pulleys connected by a 'V' belt drive where one of the pulleys has adjustable means for varying the rotational diameter of the 'V' belt.
  • This pneumatic actuation may be a close loop system for receiving commands continuously from the control means for monitoring speed variation and for adjusting pulse supply for smooth control.
  • the variator may consist of a cone dirve system comprising two cones arranged one above the other in the opposite direction. These cones are connected by a flat belt means having means for moving the belt through the length of the cones for changing the diameters of the drive and the driven means.
  • the control means is a programable microprocessor.
  • This control and the programme means are capable of storing a plurality of parameters and are designed to copy programmes between machines. This enables networking and replacement of one programme value by another. Operation of machines of any desired destination becomes possible through networking.
  • the means for sequentially loading and unloading oops in a spinning machien developed by us overcomes the above discussed drawbacks and disadvantages.
  • the base plate of the peg tray is designed to have atleast two elevated profiles symmetrically disposed thereon.
  • the pegs are arranged to sit on these profiles so that the contact between the peg and tray is restricted to the elevated profile area of the tray thereby reducing the friction considerably.
  • Plurality of perforations are introduced on the base plate of the tray to prevent congestion due to accumultion of fluff thereon during operation.
  • the gripper rail of the doffer is lowered such that each of the empty cops in the tray is encapsulated by the gripping means when idle or disabled.
  • the freedom of movement of the empty cops during operation is thereby restricted within the limits of the disabled or idle gripping means thereby avoiding fall or limiting the movement of the empty cops.
  • the surface of the peg rail may be coated with smooth electroless nickel coating upto 5 micron thickness.
  • Yet another improvement is in providing a simple bevel gear arrangement for controlling the swing in and swing out movement of the gripper arm and gripper means of the doffing device by means of level gear arrangement and linkage. This affords smooth swing-in and swing-out operation and avoids complicated and separate devices for controlling the movement.
  • Programmed control means are provided for defining and calculating the different position of the gripper movements such as empty gripping position intermediate empty cop dropping position, full cop gripping position, full cop dropping position, empty cops gripping position at intermediate rail, swing-in position as well as empty cops doffing position on spindles for different spindle lift sizes. Lifting and covering of the gripper arms are also controlled and synchronised by programmed control means such as micro processor.
  • the means for ring centering in a ring and twisting machine comprises program means, control means, actuator means and authentication means, said program means and control means actuating said actuator means to disengage the drafting drive and the drive to the ring rail, disconnecting power supply to suction means, raising the ring rail to the desired position and setting the spindle speed to enable ring centering and thereafter repeating the sequence to reset the machine to its original position.
  • the program means may also be provided with antiballoon control ring centering program which is operable either prior to or after ring centering.

  • the subject invention discloses yet another top arm assembly intended for overcoming the drawbacks and disadvantages of the existing top arm system.
  • Pressure on the bottom rollers are applied through saddles.
  • Loading function is acheived by horizontally mounted modules having spring means which can be adjusted.
  • Spring loading is transmitted to the saddles through pressure thumbs.
  • Loading brackets pivoted to the mounting means and disposed perpendicular thereto transmit the load to the saddle provided with a set of top rollers.
  • Each modular loading means is located to relate to the corresponding bottom roller.
  • the mounting and loading brokets are pivoted such that the distance between the thumb and the pivoting point and the distance between the pivoting point and the distribution point is equal so that the spring load produced is equal to the load desired.
  • the loading lever is pivoted to a support member and is kept rigid by engaging the locking lever with the fixed rocking cam in the support member.
  • the top arm can be kept upright and unlocked by disengaging from the fixed cam and placing the lever on top of the cam.
  • the top arm assembly for textile machines having modular loading means comprises a support member having a loading lever provided with atleast one horizontally disposed mounting means, each said mounting means having a spring actuated pressure thumb, an adjusting means and loading bracket terminating in a saddle and top rolelr assembly and a locking lever movably disposed on a locking cam fixed on said support member.
  • Bottom rollers are also segmented such that stopping of one set of rollers would not affect the running of the other rollers on the same or opposite sides.
  • Maintenance schedule also may be preprogrammed for sequentially engaging and disengaging each segment of the rollers such that during the maintenance of one set of rollers, the production and running of the other portions of the machine are not affected. The downtime is thereby reduced as much as 50%.
  • Ring frames are provided with plurality of suction tubes below the bottom cylinder to suck the fibres in case of end breaks.
  • suction pressure at the suction tubes drop significantly at the far end of the suction system.
  • the suction efficiency is considerably improved as suction systems are provided on both ends of the machine deviced by us.
  • Conventional spinning machines are provided with spindles in a row on both sides of the longitudinal section.
  • the front roller of the drafting zone is arranged diagonally above the spindle.
  • the drafted roving travels through the front roller and reaches the spindle through a lappet arranged in alignment with the centre of the spindle.
  • lappet travels up and down to introduce a twist in the yarn, upto the nipping points. This also helps to maintain uniform tension in the yarn for winding it on a bobbin mounted on the top part of the spindle.
  • Angles formed by the yarn in respect of the vertical plane of the lappet is known as the spinning angle and is determined by the height and distance between the nipping point of the yarn in the front roller and the centre point of the lapper.
