Definitions
- the invention relates to a winding unit according to the Preamble of the first claim.
- the thread swings in as it is pulled off the payout spool Balloon shape around the sleeve and also performs through the frustoconical
- the thread is deposited on the package through the ring bench on the spinning machine requires a ring bench movement.
- the thread travels on the top layer of the Dispenser spool always from the sleeve to the outer peripheral surface, the Balloon diameter changed from narrow to wide.
- On the peripheral surface of the The bobbin spins the yarn at the highest speed and thus forms even the largest balloon.
- the thread swinging in a balloon influences the force to be applied, with which the thread must be withdrawn from the payout spool.
- Particularly extensive swinging balloons exert a high tensile force on the thread.
- This Reason was tried early on to influence the behavior of the from the spool thread to take off.
- the object of the present invention is to determine the flow behavior of a thread a spool, a cop, so that a high Winding speed can be achieved with a low disturbance rate.
- the invention is based on not eliminating balloon formation as it does is known for example from DE-AS 1,178,337, or to break the balloon, as it is known for example from US Pat. No. 3,718,296, but the thread in to swing a balloon, but a guide surface for the thread to be provided, which affects the balloon formation.
- the thread guide surface has the shape of a truncated cone, the Opening with the larger diameter facing the payout spool. Of the The truncated cone is so penetrated by a truncated pyramid that the Push the corners of the truncated pyramid through the truncated cone.
- the Penetrations form notches.
- the conicity of the truncated cone and the The truncated pyramid shell points in the same direction.
- the axes of The truncated cone and the truncated pyramid coincide.
- the Cross-sectional areas of the truncated pyramid are equilateral, odd-numbered Polygons.
- the device according to the invention which serves as a trigger accelerator, has compared to the conventional trigger accelerators the advantage that the forming thread balloon is not destroyed or completely suppressed, but shaped becomes.
- the notches in the truncated cone contribute to this through the penetrations of the truncated cone of the Truncated pyramid be generated.
- the one on the Thread striking the truncated cone surface area migrates in the unwinding direction seen along the wall of the truncated cone until it hits a Penetration meets. There the thread movement is caused by the impact of the thread temporarily stopped on one of the surfaces of the penetrations and the thread in disturbed his movement, but without being stopped suddenly or for a long time to be thrown completely out of its path.
- Thread take-off accelerator ⁇ becomes the thread much weaker forces exposed and thereby protected. This applies in particular if the Cross-sectional areas of the truncated pyramid an equilateral pentagon represent.
- Notches Five evenly arranged on the circumference of the truncated cone Notches have the advantage that the surfaces of the notches are at an obtuse angle stand in relation to each other and thus the impact surface of the thread in one obtuse angle to the tangent to the peripheral surface of the truncated cone the transition point to the notch.
- a pentagon offers enough Impurities for the rotating thread, as a rule when the thread is rotating not all notches contribute to the thread disorder.
- the area fractions are Penetrations of the truncated pyramid through the truncated cone at most as large as the surface area of the truncated cone. This will an excessive indentation due to the penetration of the truncated pyramid avoided. It also prevents the interference of the thread balloon so become massive that the thread balloon collapses completely and the thread wraps around the sleeve loops.
- the notches must be designed so that on the Transition point from the truncated cone to the notch, in the direction of the thread seen the tangent to the truncated cone surface on the opposite surface the adjacent notch. This area is said to be at an obtuse angle of the striking tangent, so that an abrupt change in direction of the striking thread is avoided.
- the conicity of the Truncated cone and the truncated pyramid on the thread mass Voted.
- the Thread mass has an influence on the balloon formation. With larger thread mass more bulbous thread balloons form, so that the inlet into the Thread take-off accelerator takes place at a flatter angle than one lighter thread, due to its balloon formation with a steeper angle comes in. In the case of an unfavorable adjustment of the taper to the yarn mass, with too steep cone angle, it can lead to massive constrictions of the balloon and thus to disadvantageously suppress the thread balloon or break the Thread balloons come, which means the thread balloon collapses.
- a payout spool 1, a cop is not closer to one in the payoff position shown but known from the prior art winding unit Dishwasher.
- the sleeve 2, on which the package 3 is wound stands on one Push-on mandrel 4 of a transport pallet 5.
- the thread is from the conical tip 7 of the package 3 is withdrawn. Due to the Ring bench movement when spinning is the thread in side by side Coils placed on the conical tip 7 of the package 3 and migrate when pulling off according to its storage during the spinning process between the sleeve 2 and the peripheral surface 8 of the package 3 constantly back and forth.
- Thread balloon 9 During this withdrawal movement, the thread executes one around the sleeve 2 oscillating movement and thereby forms a so-called thread balloon 9. With the help of the device 10 for influencing the thread run at the winding point Influenced on the formation of the thread balloon 9.
- Trigger accelerator called, is arranged above the payout spool 1. Of the Thread 6 enters and leaves the device 10 from the inlet side e on the exit side a.
- a pre-cleaner 11 is located above the trigger accelerator and a thread tensioner 12 are arranged. In the pre-cleaner are already rough Thread defects and loops caught.
- the thread balloon 9 swings when it passes through the so-called pull-off accelerator 10 would not be affected, between the detachment point 13 of the thread 6 of the Package 3 to the first thread guide point, in this case the pre-cleaner 11. With a thread in the take-off direction 14 from a p-wound pay-off spool 1 is withdrawn, the thread balloon 9 swings clockwise 15.
- the device 10 for influencing the thread run in their Details shown. It shows a sight of the so-called Thread take-off accelerator from the inlet side e of the thread, ie from the Direction of the spool.
- the thread take-off accelerator 10 of the present exemplary embodiment exists from a solid block of material, preferably aluminum, in which the Contours influencing the thread run are introduced.
- a correspondingly shaped metal sheet could also be provided, which the in the solid part introduced contour 16 encloses from the outside.
- the material was first removed in a conical shape, so that the inner contour 16 primarily forms a truncated cone jacket 17.
- This A truncated cone 17 is penetrated by a five-sided pyramid P.
- the Edges 18 of the truncated pyramid penetrate the truncated cone evenly.
- the symmetry axes p of the pyramid fall and k of the cone together. This ensures even penetration of the Pyramid edges given by the truncated cone.
- the further one The prerequisite for a uniform penetration is the matching one Taper of cone and pyramid. So in the present embodiment the cone angle 16 ° and the angle between a pyramid edge 18 and the Axis of symmetry k of the pyramid 10 °.
- Different conicity for example a steeper conical surface, which leads to a stronger formation of the Notches in the infeed area of the thread, does not improve the running behavior of the thread.
- Two sides of a pyramid P abut the pyramid edges 18 together. These two sides result in a notch 19 in the Truncated cone shell 17.
- the surfaces 20 and 21 of the truncated pyramid shell are taken together a maximum of the same size as a neighboring one Part of a truncated cone between two notches 19. Because the cross-sectional areas of the truncated pyramid p are equilateral, odd polygons and Triangles and quadrilaterals as cross-sectional areas are excluded, close in each case two truncated pyramid surfaces 20 and 21 form an angle 22 which is about 90 degrees. It is an obtuse angle.
- the notches 19 are chosen so that a thread that runs along a Truncated cone surface 17 moves, then on one of the surfaces 20 or 21, depending on Direction of rotation of the thread hits when the thread is tangent to the contour edges 23 or 24 of the truncated cone surface areas 17 into a notch 19th is moved.
- the present contour of the trigger accelerator 10 is suitable for the Thread run both when unwinding q-bobbins and p-bobbins among the to influence the same conditions.
- the outer contour 29 of the trigger accelerator 10 is round and has a flattening 30.
- On the flattening 30 is, as from 3 shows a threaded bore 31 for fastening the Take-off accelerator 10 at the winding unit.
- the inner contour 16 has no inlet slot for the thread.
- the thread must therefore be exemplary, for example by means of pneumatic Aids are promoted by the inner contour 16. For example by blowing from the thread inlet side e and sucking from the thread outlet side a done here.
- Figure 3 shows a view of the inner contour 16 according to the section, as he is located in Figure 2.
- the matching one is clearly visible Conicity of the truncated cone 17 and the penetrating it Truncated pyramid P.
- the axis k of the cone and p of the pyramid fall together.
- the cone angle 32 of the cone is in the present case Embodiment 16 °.
- the trigger accelerator 10 of the Thread inlet side e ago has a frustoconical recess.
- the lower one Edge contour 25 of the inner contour 16 does not coincide with the lower edge u of the Trigger accelerator 10 together.
- the upper edge contour 33 of the inner contour 16 coincides with the top, the outlet side a, of the trigger accelerator 10 match.
- the inlet side e in the present embodiment as a truncated cone a much larger conicity than the truncated cone Inner contour, can also be dome-shaped.
- the inlet side e serves in particular to initiate the blow-up or thread to be sucked up into the take-off accelerator 10.
- the actual inner contour 16 front inlet side e the looping of Thread around the edge of the lower edge contour 25. It goes without saying that both the lower edge contour 25 and the upper one to protect the thread Edge contour 33 are not sharp-edged, but are rounded.
- FIG 4 shows an embodiment of the trigger accelerator 10, which in the Formation of the inner contour 16 with that shown in Figures 2 and 3 Embodiment matches.
- the thread is not by means of pneumatic tools through the inner contour 16 of the Trigger accelerator 10 blown through, but by means of a gripper tube captured above the cop 1 and below the trigger accelerator 10 and inserted into the trigger accelerator 10 by means of the gripper tube, contains the Trigger accelerator 10 on its circumferential contour 29 an insertion funnel 34 which opens into a slot 35.
- This slot 35 should not significantly affect the yarn thickness exceed.
- the slot 35 opens into the Inner contour 16, where one edge 18 of the pyramid would lie, i.e. where two Butt surfaces of the truncated pyramid 20 and 21. At this point it is Low risk that the thread circulating within the inner contour 16 through the Slot 35 is thrown out.
- the Cone angle 32 of the truncated cone 17 is between 15 ° and 60 °, the inclination the truncated pyramid surfaces between 5 ° and 35 °, preferably at 8 °.
- the Diameter of the opening formed by the truncated cone 17 in the Thread outlet side a is between 20 mm and 45 mm, preferably 30 mm and the height of the thread take-off accelerator is between 20 mm and 70 mm, preferably at 40 millimeters.
- Triangular trigger accelerators disproportionately often peak loads in the Range from 80 cN to 120 cN.
- Pull-off accelerators are peak values in the range from 100 cN to 120 cN a negligible number has dropped.
- the forces acting on the thread are essential sunk. It is the essence of the invention, the level of the voltage peaks dismantle and place them in an area where the influence on the Deduction behavior and the quality of the yarn is much lower.
