Definitions

  • the present invention relates to yarn winding and unwinding mechanism in a spinning textile mill. More particularly it relates to a spindle and ring frame tube assembly for spinning textile mill which prevents any slippage between the spindle and the ring frame tube from the beginning of winding to the end of winding.
  • finished yarn is customarily wound onto carriers for storage and shipment.
  • carriers called ring frame tubes or bobbins
  • bobbins are typically hollow forms which are cylindrical or conical in shape.
  • Manufacture of yarn is carried out as a continuous operation, and as part of the manufacturing process, machines have been developed to automatically package yarn by winding it onto bobbins for storage, shipment, and sale.
  • the standard yarn winding process includes frictionally engaging or snagging the yarn end from an upstream source with a rotating bobbin so as to connect the yarn end to the rotating bobbin and cause winding of the yarn supply onto bobbin or the resulting yarn "package" will be improperly wound and therefore unsuitable for shipment.
  • Ring frame tube which is mainly an elongated spool or reel on which thread is wound in textile industry.
  • the said bobbins get displaced from the spindle at higher speed due to the lack of proper gripping resulting into the damage to the bobbins, bolsters sitting on the spindle and bearings which ultimately results into the increased production cost.
  • paper bobbins were invented which also have certain disadvantages as stated hereinafter.
  • the paper bobbins are weak and allow the cone to breakup.
  • the Paper bobbin can not handle much heat hence the low paper rating even though the wire employed has a higher temperature rating than the bobbins.
  • the paper bobbins cannot bear high humidity as moisture greatly weakens the paper strength and shrink due to heat. Further due to non reusability and above mentioned problems, the paper bobbins failed to fulfill the needs of textile industries and also the production cost for such bobbins increases.
  • plastic bobbins were invented.
  • the plastic bobbins do not provide necessary grip to the bobbins as result they start vibrating and the said bobbins get displaced at high tension of the Yarn resulting into the unbalance in the spindle.
  • the bolster on which the said spindle is fitted gets wear and tear and due to that the bearings in the said bolster is damaged and starts getting jammed due to which, the said spindle does not run at required speed resulting into the loss of production.

  • the spindle (SP) as shown in figure 16 generally having elongated structure.
  • the spindle (SP) can be cylindrical or conical in nature.
  • the spindle (SP) comprises head (H), body (BD) and base (BS).
  • the head portion (H) includes means in the form of at least three buttons (Bl, B2, B3) which protrude as the spindle starts rotating.
  • the body portion (BD) includes tapered design over its periphery.

  • the ring frame tube (RT) is shown in figure 1.
  • the ring frame tube (RT) can be cylindrical or conical in nature.
  • the ring frame tube (RT) includes an outer surface (OS) and an inner surface (IS).
  • the outer surface (OS) plays very important role for yarn winding and unwinding. It is desigened in such a way that it holds the yarn very firmly.
  • the outer surface (OS) has five parts (PI, P2, P3, P4, P5).
  • the first part (PI) defines a smooth surface.
  • the first part (PI) plays a vital role while winding and unwinding of the yarn at high speed. Due to smooth radius it helps in reducing the hairiness on the yarn.
  • the second part (P2) is in continuation to first part (PI).
  • the second part (P2) includes a plurality of grooves (SG) over its periphery.
  • the grooves are shown in figure 3.
  • the second part (P2) is the final area where the winding is getting completed.
  • the groove depth in this part is given more to disallow the yarn sluff off and to cause the yarn to catch its position perfectly and avoid movement.
  • the grove edges are designed in such a way that there is minimum yarn breaks due to different stresses or friction which is created at high speed between the yarn and the tube grooves.
  • the distance between the two grooves is maintained perfectly so that yarn is caught tightly between the grooves (SG).
  • the dimensions of the grooves (SG) are as given below:
  • Pitch is from 2mm - 15mm
  • Depth of the Groove is 0.005 to 0.12mm
  • the third part (P3) is in continuation to the second part (P2).
  • the third part (P3) comprises a plurality of microgrooves (MG) over its periphery.
  • These grooves (MG) are made in such way that while tube is running on High Speed of more than 15,000 RPM, as the yarn touches the grooves, the grooves catches it very tightly and starts winding. Accordingly the distance between the two grooves is designed.
  • the grooves most end top is given a radius due to which yarn slips and makes it self adjusted tightly between the two grooves.
  • the dimensions of the grooves (MG) are as given below:
  • the distance between the two micro grooves varies from 0.1mm to 1 mm.
  • the Distance majorly depends upon yarn material, yarn count and machine speed.
  • Depth of the micro groove as shown in detail in figure 4 varies from 0.005 to 0.1 mm such that at least one layer of yarn sits in it properly. Secondly as the depth is accurate, it does not allow the yarn to come out from the grooves unless it is un winded in a proper manner.
  • i. Right Hand Direction This is the direction in there are chances of yarn to get slipped off and yarn do not sit properly within the grooves. Hence only some of the grooves are made in said direction. ii.
  • Left hand direction Remaining grooves are made in left hand Direction; this is the opposite direction in which the tube rotates. As the direction of winding go upwards the tube groove move in the down wards direction. Due to this the grooves catches the yarn very tightly and with even strength. It also gives support to the yarn to sit properly.
  • This technique solves the problem of sluff off of the many layers of yarn, slippage of the yarn during the process of unwinding. Due to this yarn hard wastage is next to zero, and no need of cleaning the tube for reuse. It reduces the ideal time of the tube. So the repeat use of the tubes is very fast.
  • the second important benefit is the left hand direction grooves even works while winding and unwinding of the Cotton Yarn, Polyester Yarn, Poly Viscose which was not perfectly possible till date.
  • the fourth part (P4) is in continuation to third part (P3).
  • the fourth part (P4) comprises a plurality of grooves (FG) over its periphery.
  • the fourth part (P4) is the place or area from where the Winding of the tube starts.
  • the groove depth in this area is less as compared to most top area defined by second part (P2) as shown in figure 5.
  • the Groove depth in general is only 0.01. This depth is less because, as during the start up of winding, if due to any reason the yarn breaks up, the initial winded up yarn comes out smoothly, and it can start the winding again.
  • This area of groove plays a vital role in winding process, during the machine starts up. This helps in getting the tube exact quantity of yarn and the yarn winding is done properly.
  • the dimensions of these grooves are as given below: Pitch 2mm to 15mm
  • the fifth part (P5) of the ring frame tube is a collar.
  • the collar sits on the base portion (BS) of the spindle (SP).
  • the inner surface (IS) of the ring frame tube (RT) includes tapper design.
  • the tappers on inner surface (IS) are designed exactly as per the tappers of the spindle (SP) in such way to minimize the air gap between the spindle (sp) and the ring frame tube (RT).
  • the air gap between the spindle (SP) and the ring frame tube (RT) ranges from 0.1mm to 0.7mm.
  • the tappers on inner surface (IS) are constructed in the form of grooves, ribs, spilines or in any other similar pattern. This design of tapper guides the ring frame tube (RT) to rotate at high speed as the winding starts and keeps it in position, so that there is negligible lifting and no displacement of ring frame tube (RT) from the spindle (SP).
  • Air gap between ring frame tube (RT) and spindle (SP) depend upon yarn material, yarn tension, twisting of yarn and heat treatment of yarn.
  • the tapered design on inner surface is provided over its periphery which is covered by the third part (P3) of the outer surface (OS).
  • the ring frame tubes are mainly made of but not limited to the plastic material.
  • the material selection solely depends upon the yarn type and quality. Some of such materials are given herein after which are only for the purpose of examples and by any way does not restrict the invention. 1. Polycarbonate & Filler up to 33%
  • the tubes are majorly manufactured out of Poly Carbonate Granules. Use of polycarbonate is about 90 % because it has got very good Melt flow, very excellent Notch Impact Strength, Very good flexural of Modulus.
  • the different Materials (fillers / chemicals) are as follows:
  • the Glass Fiber percentages also depends on what's the Tensile Strength of Yarn, Yarn Tension, and if Yarn twisting Strength is more in that case we have to add more percentage of Glass Fiber, so that the Hollow Tube don't collapse due to the yarns pressure while winding.
  • the Tube When the Tube is made out of Polycarbonate using different Combinations of the materials listed above, it can run (rotate) up to 25000 RPM using the same designs, as shown in the figure. But as of today major tubes of other manufacturer are running maximum up to only 18000 RPM.
  • machine can be run at up to higher speed of 40% and due to that whole process can be completed in very less time of winding, unwinding and so on. So over all it increases the production by 10% - 15%.
  • ABS Alloys with Glass Fibers 8& fillers up to 33%
  • the assembly of the present invention also includes an insert (INT) which is fixed inside the ring frame tube (RT).
  • the insert occupies some portion of the second segment and some portion of the third segment.
  • the insert (INT) can be short or long in size.
  • Such short and long inserts (SINT, LINT) are shown in figures 6 to 18. Due to long Insert the ring frame tube gets more outside radius, so winding and unwinding of yarn become smooth and also it avoids hairiness in yarn.
  • These inserts are placed inside the ring frame tube at the time of moulding of the ring frame tubes.
  • the inserts (SINT, LINT) provides grip to the ring frame tube (RT) over the spindle (SP).
  • the inserts can be made of different material. Some of them are as discussed herein after by way of examples and not restriction. i. Plastic material: The use of plastic material offers many advantages like:
  • the assembly of the present invention may include a sleeve (SL) which is placed between the insert (INT) and the inner periphery of the ring frame tube.
  • the sleeve (SL) provides additional grip to ring frame tube over spindle.
  • the sleeve (SL) can be made of magnetic material or steel material.
  • the sleeve (SL) creates stronger gripping between itself and the spindle buttons (Bl, B2, B3) and gives a good relative velocity. As there creates an attraction towards the magnet, so the buttons at once comes out and catches the magnetic sleeve, and so before the spindle starts rotating the tube is properly stuck with the spindle button, and this gives a great relative velocity & positive drive.
  • the spindle textile mill can run up to 25000RPM of speed.
