Definitions
- the invention relates to a ring spinning device with at least one spinning station, the one
- Such a ring spinning device is known from JP62-231039 A.
- False twisting device contains a sieve drum to which the fiber structure coming from the drafting system and to be twisted is applied.
- the fiber structure runs over the peripheral surface of the sieve drum.
- the axis of rotation of the screening drum is arranged parallel to the fiber structure.
- a suction insert is arranged, over which the fiber structure is sucked up to the surface of the sieve drum. Due to the rotation of the sieve drum, the false twist is imparted to the fiber structure sucked onto the circumferential surface.
- Rotation propagation in the fiber structure, starting from the ring spindle, is often hindered by the fact that between the output roller of the drafting system and the ring spindle
- Thread guide is arranged. This thread guide is also called "Sauschwänzchen”.
- Yarn breakage is significantly increased. Overall, the operating and maintenance costs of the ring spinning machine can not be reduced by such false-twisting devices, even if the number of yarn breaks is reduced.
- the invention has for its object to provide an improved false twist device for a ring spinning device.
- the false twist device has at least one rotatable disc with a friction surface for the fiber structure.
- the sliver to be twisted rests on the friction surface of the rotating disk and is rotated around itself by the friction surface and thus receives a false twist. Compared to a pneumatic false twist device significantly less energy input is required for the false twist device according to the invention.
- the fiber strand to be twisted applies itself to the friction surface of the rotatable disc. There is no threading required.
- the friction surface is preferably arranged on the outer circumference of the disc.
- the rotation of the fiber structure can be temporarily increased, so that the risk of yarn breakage is reduced.
- the rotation of the fiber structure in the region between the output clamping line of the drafting system and the false twist device can be increased.
- the strength of the fiber structure in its weakest area immediately after the Ninklemmline, where the spinning triangle is located, is thereby increased. It is advantageous that the fiber structure is guided by two adjacent disks, which are arranged with an axial distance which is smaller than the disk diameter. Two adjacent disks overlap and a wedge gap is created. The fiber structure settles in the wedge gap of the two adjacent disks and is securely positioned there. Through the friction surfaces of the two discs, the fiber structure is given a rotation. The adjacent discs rotate in the same direction.
- the false twist device so upstream between an output terminal line of the drafting and one of the ring spindle
- Thread guide is arranged that the fiber strand is deflected by the false twist device from the shortest connecting line between the output terminal line and thread guide. This arrangement is particularly advantageous when the fiber structure is guided in a wedge gap of two adjacent disks.
- the axis of rotation of the disc has an angle to the fiber structure, so that the false twist device a
- Output terminal line the fiber strand is no longer exposed to so much tension and the risk of yarn breakage is greatly reduced.
- each spinning station may associate with a false twisting device which has two rotatable discs.
- the axes of rotation of the two disks associated with the fiber structure may have a small angle to one another. The two axes of rotation are thus entangled with each other.
- the disk diameter of the rotatable disk is greater than the pitch of the ring spinning device.
- the number of discs in the ring spinning device is then one slice higher than the number of juxtaposed spinning stations. This embodiment is particularly advantageous if the Division of the ring spinning device, so the distance from spinning station to spinning station is very small, as is common in the processing of short staple fibers.
- Figure 1 is a schematically illustrated side view of a Ringpinnvorriehtung with a
- FIG. 2 shows a very schematic view in the direction of the arrow II of FIG. 1 on two adjacent false-twisting devices
- FIG. 3 shows a view similar to FIG. 2 of a differently configured false twist device
- FIG. 4 shows a very schematic view of a false twist device in the direction of the arrow IV of FIG. 1.
- FIG. 1 shows very schematically a spinning station 1 of a ring spinning device 2.
- the spinning station contains a drafting system 3, a false twisting device 4 and a ring spindle 5.
- drafting system 3 is only that of a lower roller 6 and a pressed thereon
- Top roller 7 existing output roller pair 6.7 shown.
- the drafting system 3 may include in a conventional manner further roller pairs, not shown, to forgive a fiber structure 8 of staple fibers to the desired fineness.
- Output roller pair 6.7 the fiber structure 8 is finished warped and is delivered in the transport direction A to the ring spindle 5.
- the ring spindle 5 includes a cop 10 for winding the twisted into a yarn
- the cop 10 is rotated.
- the ring spindle 5 is associated with a spinning ring 11 and a ring traveler 12.
- the ring spindle 5 is preceded by a thread guide 13, which is also referred to as "Sauschwänzchen.”
- the fiber structure 8 delivered by the drafting system 3 passes through the thread guide 13 and the rotor 12 and is wound on the cop
- the spinning rotation runs back counter to the transport direction A to the pair of output rollers 6, 7 of the drafting system 3.
- a spinning triangle can be produced be present, which represents the weakest point of the fiber structure between the output clamping line 9 and ring spindle 5. Due to the friction of the fiber structure 8 on the yarn guide 13, the running back of the spinning rotation to the drafting 3 is hindered.
- the false twist direction 4 is arranged between the pair of output rollers 6, 7 and the thread guide 13.
- the false twist device 4 includes a rotatable disc 14, which at its
- the disc 14 is fixedly mounted in the ring spinning device 2 via a bearing 17 and a holder 18.
- the disc 14 is connected to a whorl 19 which is driven by a belt 20.
- the disc 14 may be associated with its own drive motor.
- the false twisting device 4 is arranged between the output clamping line 9 and the yarn guide 13 such that the fiber structure 8 is deflected by the false twisting device 4 from the shortest connecting line between the output clamping line 9 and yarn guide 13.
- Tensile stress is thereby applied to the friction surface 15 of the disc 14 and can be rotated by the rotating disc 14.
- the fiber structure 8 is deflected at the friction surface 15 of the false twist device 4.
- the fiber structure 8 is guided by two adjacent disks 14 which are arranged with an axial spacing which is smaller than the disk diameter.
- the two adjacent disks 14a and 14b are arranged offset in the axial direction of the axis of rotation 16 to each other.
- the arrangement of two adjacent disks 14a and 14b of the false twist device 4 is shown in FIG.
- the two adjacent discs 14a, 14b overlap and thereby form a wedge-shaped gap 21, in which the
- Fiber Association 8 of the spinning station 1 is performed.
- the two disks 14a, 14b rotate in the same direction in the direction of rotation B. Both disks 14a, 14b are driven via their whorls 19a, 19b by a common tangential belt 20.
- One adjacent to the spinning station 1 is driven via their whorls 19a, 19b by a common tangential belt 20.
- Spinning station 1 'for processing a fiber strand 8' contains its own false twist device 4 ', which also contains two discs 14a', 14b '.
- the false twist device 4 'of the adjacent spinning station 1' is driven by the same belt 20, which preferably passes through the entire ring spinning device 2.
- a deflection roller 22 may be provided for the belt 20.
- the distance of the neighboring ones Fiber dressings 8 and 8 'in the ring spinning device 2 are also referred to as "pitch.”
- the outer diameter of the pulleys 14 is smaller than the pitch of the ring spinning device 2.
- FIG. 3 shows a variant of a false twisting device 4. Similar to FIG. 2, two adjacent spinning stations 1 and 1 'are shown. The fiber structure 8 is guided in the wedge gap 23 by two adjacent disks 24 and 25. The fiber structure 8 'of the adjacent
- Spinning station 1 ' is guided by a wedge-shaped gap 23', which is formed by the disk 25 and a further disk 26.
- the outer diameter of the discs 24, 25, 26 is greater than the pitch of the ring spinning device 2.
- the center distance of the discs 24, 25, 26 is smaller than the disc diameter. There are a total of fewer discs required in this variant.
- the number of disks corresponds to the number of juxtaposed spinning stations plus another disk at the beginning.
- Fiber structure 8 has. So that the false twist device has a conveying effect on the
- Fiber Association 8 exercises.
- the conveying effect is preferably directed opposite to the transport direction A, so that the tensile stress of the fiber structure 8 in the area between
- FIG. 8 A preferred embodiment of a false twist device 4 with a conveying effect on the fiber structure 8 can be seen in FIG.
