Definitions
- the present invention relates to a device for winding a thread on a rotatable, conical sleeve to a bobbin with a rotatable friction roller, which comprises a plurality of cylindrical rotation elements arranged one behind the other on a common, driving shaft, one of which is fixedly connected to the shaft and which is in contact with the sleeve or the coil along a surface line, the coil and roller rolling against one another during operation.
- conical, i.e. frustoconical sleeves For winding a thread or yarn into a bobbin, the use of conical, i.e. frustoconical sleeves desired.
- the rotation of the sleeves required to manufacture the bobbins is generally generated by a cylindrical drive roller which lies along a surface line on the sleeve or on the thread material already wound on the sleeve.
- the sleeve or spool is entrained by the drive roller due to friction. Since the sleeve is conical and the drive roller is cylindrical, the surface velocities of these rotating bodies do not coincide along the surface line mentioned.
- the outer surface of the coil moves faster and at locations with a relatively small diameter of the sleeve the outer surface of the coil moves more slowly than the surface of the drive roller.
- the surfaces touching each other at these points rub or rub against each other, which is undesirable since the quality of the wound threads suffers.
- German Offenlegungsschrift No. 2 228 488 discloses a device according to which, for the purpose of maintaining the winding speed and the uniformity of the yarn tension in the distribution cylinder, its contact surface with the bobbin is kept narrow. This significantly reduces chafing of the surface of the coil and distribution cylinder. In the case of a narrow contact surface, however, the clutch between the coil and the cylinder, which is based on friction, and therefore also the driving of the coil proves to be insufficient.
- the abrasive effect mentioned is to be reduced to a great extent by the present invention and nevertheless reliable drive of the sleeve or coil is to be ensured.
- the entrainment should namely be comparable to that of an undivided drive roller on a cylindrical spool.
- the invention is characterized in that a central element of the friction roller is fixedly connected to the shaft in terms of rotation, and on each of its sides a further element of the friction roller is rotatably mounted on a rotary bearing attached to the shaft and that the other two elements are connected by a differential gear are coupled together.
- the coupling of the three elements ensures that they support each other in terms of drive, which equates to a particularly large friction surface for the drive; i.e. the friction surface is the same as if the friction roller were not subdivided, but rubbing is practically avoided.
- a sensitive rubber friction lining is not necessary according to this solution, even under conditions in which one is normally used.
- FIG. 1 shows a spinning unit 11 in which a sliver 13 is spun into a yarn or thread 14. Conveyor rollers 15 move the thread 14 upwards. This passes through two thread eyelets 16, 17, which represent an arrangement that compensates for variable thread lengths. For this purpose, for example, the thread eyelet 16 is biased in the direction of arrow 18 by a spring or a weight and movable back and forth along the dash-dotted line.
- the thread 14 runs from the thread eyelet 17 to a thread guide 21, which is located in front of a rotatable rubbing roller 22.
- the friction roller 22 comprises, in a manner known per se, a shaft 23 which is driven from the outside and on which three elements 24, 25 and 26 are attached.
- the elements 24 and 26 are freely rotatably supported on bearings 27, 28.
- the element 25 is firmly connected to the shaft 23.
- the thread guide 21 moves back and forth parallel to the shaft 23 over the length of the bobbin 32.
- the shaft 23 and thus also the element 25 fixed with it are set in rotation.
- these take the coil 32 pressed against the friction roller 22 or, at the start of a winding process, the pressed sleeve 31 with them, so that the coil 32 or the sleeve 31 is also set in rotation.
- the thread 14 is wound up by the rotation of the friction roller 22 and the bobbin 32.
- the back and forth movement of the thread guide 21 ensures a uniform distribution of the thread 14 to be wound.
- the coil 32 and the cylindrical friction roller 22 abut one another along a surface line.
- all points of the surface of such a roller would have the same surface speed.
- all points on its jacket-shaped surface have the same angular velocity, but the surface velocity, i.e. the distances of the points of their surface covered per unit of time are the smallest at the location of the smallest coil diameter (on the left in FIG. 1) and the greatest at the location of the largest coil diameter (on the right in FIG. 1).
- the surface speeds of the previously assumed single-body rubbing roller 22 and the spool 32 are the same only at the location of their centers, relative to the axial direction of the rubbing roller and spool. It follows that on the surface line on which the rubbing roller 22 and the spool 32 abut one another, there is mutual rubbing or rubbing, which is greater the closer one is to the lateral ends of the rubbing rollers and the spool and each longer the friction roller and spool. This rubbing against each other causes damage to the wound material, particularly at the outermost points of the coil 32.
- the friction roller 42 in turn comprises a shaft 43 on which the elements 44, 45, 46 are attached next to one another.
- the elements 44, 46 are in turn rotatably mounted on bearings 47, 48, and the element 45 is fixedly connected to the shaft 43.
- the element 45 has two bores running parallel to the shaft 43 and lying next to one another.
- a transmission shaft 52 is rotatably mounted in one bore 51. It is provided with a gear 53 at one end and a gear 54 at its other end.
- the element 46 has the shape of a hollow cylinder and is provided on its inner wall with a ring gear 55 with which the gear 53 is in engagement.
- Another gear 56 is attached to one end of a support shaft 57, which is rotatably mounted in the second bore already mentioned. 3, this second bore lies behind the bore 51 and is not visible in FIGS. 3 and 4.
- 5 is a top view in which only the transmission shaft 52, the support shaft designated 57 and the gear wheels 53, 54 and 56 are drawn.
- the gear 56 is approximately twice as long in the axial direction as the gear 54.
- the two gears 54 and 56 are in engagement with one another.
- the gear 56 is also in engagement with a ring gear 58 which is attached to the inner wall of the hollow cylindrical element 44.
- the gear shown in Fig. 5 together with the gear rings 55 and 58 forms a differential gear.
- the element 45 is taken along and the shafts 52 and 57 rotate with the gear wheels 53, 54 and 56. Since the gear wheel 53 is in engagement with the ring gear 55 and the gear 54 via the gear 56 with the ring gear 58, the elements 44, 46 are entrained by the gear wheels 53, 54, 56 and the friction roller 42 rotates as a unit about the axis of rotation of the shaft 43. If, however, there is a coil in the position shown in FIG. 1 on the shaft 43, this causes, as previously described, a rotation of the element 46 in one direction of rotation and a rotation of the element 44 in the opposite direction of rotation relative to the element 45 Amounts.
- the outer elements can be of different lengths, wherein in the case of the example of FIGS. 3, 4, 5 a correspondingly adjusted transmission ratio of the differential gear is used. With the same length of the elements, one has the advantage that the distances over which the outer parts slide or rub are minimal.
