Abstract

Usage: in the processing of synthetic fibers. SUMMARY OF THE INVENTION: The package is formed by layered cross winding with sealed ends and has a cylindrical shape. In addition, it is made with additional compacted areas that are offset from the ends to the middle at a distance of 2 mm from the edges of the package. The difference between the maximum value of the shrinkage voltage of the yarn during its drying at the site of the highest packing density and in its central part does not exceed 40 mg / g. The package winding device has a slotted drum with main and additional intersecting grooves with curved transition portions that are offset 2 mm toward the middle of the drum. The contact roller provides pressure on the bobbin holder no more than 0 2 kg / cm. 2 sec. and 2 h. n. f-ly, 22 ill. High-speed manufacture of synthetic yarn is carried out in two ways: the so-called yarn pickup method, in which the yarn, melt-formable, is wound directly onto the package in the form of fully oriented fiber without drawing, and the so-called yarn pickup method with molded from the melt. wrapped around the package after stretching. The method of direct capture allows you to get yarn, dyed with a normal (L S h o th VJ ate with: with

pressure, which is impossible when using conventional polyester fiber with a molding speed of 7000 m / min and more and subsequent winding on the package.

The pulling method with stretching yields synthetic yarn with the same mechanical properties as conventional synthetic yarn using high-speed winding.

However, in the case of high-speed production of synthetic yarn, there are serious difficulties in winding which lead to deterioration of the package and uneven quality of the yarn is genuine.

When winding the yarn on the package, the direction of winding the yarn is changed with the help of the traverse device, and the yarn is wound through the contact roller on the reel mounted on the shaft. Since the traverse yarn is reversed at a reduced speed, yarn accumulation occurs at both ends of the package, as a result of which parts of the package at the edges of the end parts protrude outwards. The package diameter in areas with high edges becomes somewhat larger than the middle part. In addition, the density of the winding sections with high edge is higher compared with the middle part. Therefore, during the winding of the package, only the high-edge areas are pressed against the rotating contact roller.

Until now, it is not known that a cheese-like package of synthetic yarn wound at a speed of 5000 m / min and above, which is characterized by high shape stability and minor defects in uneven dyeing, if it is used directly for the production of fabric or knitwear.

The aim of the invention is to improve the performance properties of a package of synthetic freshly formed yarn and a device for winding it.

The polymer is extruded through dies.

0 1, mounted on a uniformly heated molding head 2, in the form of filament material. The thread is slowly cooled in the tube 3, then is cured by the cooling air supplied from channel 5. The plurality of filaments forming yarn 5 is assembled together with the finishing additive through the lubricating nozzle 4. Straight 5 is wound through the traverse guide 8. located below lubricating nozzle

4, using a winding device to obtain package 9.

The winding device comprises a bobbin holder 11, carrying a bobbin 10 and connected to drive means 26 connected with inverter 14, and a contact roller 24 mounted on a bearing in a housing. A pulley23 located at one end of the contact roller 24 is driven by the belt 22 by means of driving means 20. The driving inverter 25 is connected to the driving means 20 of the contact roller. A series of holes 13 used to control the rotation of the roller 24 is located at the other end thereof. A means of controlling the rotational speed 12 of the non-contact type is located opposite the apertures 13 of the roller 24 and is connected to a controller 15 including a calculation for controlling the speed of rotation of the shaft of the reel, which is connected to the driving inverter of the shaft of the reel.

The drive spreader 27, FIG. 2a, slotted drum includes a cylindrical cam 19 mounted on two bearings, and the yarn guide 18, one end of which is inserted into the helical cam groove 19. Moving nige- driver in a vertical direction limited by a pair of rails 17.

A cam 19 is connected to a driving device 16 coupled to a driving inverter (not shown) of the cam.

The drive means 20 are pressed against the shaft of the reel 10, the spreader 27 and the roller body 28 cooperate with the movable base 31 housed in the frame 29 of the winding device. The base 31, mounted on a support with the spreadsheet 27 and the housing 28 of the contact roller, slides along a shaft 30 placed in the frame 29 and is fed up and down by means of a pneumatic cylinder 32.

FIG. 3 shows a detail of the device for the contact roller 24, the shafts 61a and 616 projecting from two ends of the roller 24. are mounted on bearings 333 and 336 in the bearing housings 34a and 346, respectively. The bearing housings 34a and 346 are fixed to the housing 28 of the contact roller. Bearing caps 35a and 35 are used to support 3h and 336 bearings in bearing housings 34a and 346. The pulley 23 is mounted on the shaft 61a by means of the cuff 36 and the washer 37 and secured with a screw 38. The belt 22 is located between the pulleys 23 and 21 fixed to the electric motor 20. A series of holes 13 are located on the peripheral surface of the end portion of the contact roller 24.

FIG. 4 shows a block diagram of the controlling means 15 of the coiler. Signals transmitted from a non-contact speed control device

rotation 12, which determines the rotational speed of the contact roller 24 by registering the holes of the row of holes 13, is fed into the pulse counter 71. The pulse counter 71 adds the number of holes 13 that pass during the measured time interval emitted by the measuring clock pulse generator 70. A series of clock pulses is transmitted in the order of 1 MHz from the reference clock generator 74, and the clock counter 72 sums the number of clock pulses during the measured time interval emitted from the measurement gene clock pulse racer 70. Actual speed

0, the rotation of the contact roller 24 is determined by the number of apertures passing during this time interval and clock pulses during this time interval with the aid of a work amplifier 73.

5, the rotational speed and theoretical rotational speed determined by the yarn speed setting device 75 are compared with a comparator 76 to determine the difference between them. The required change of control is determined by this discrepancy, and the control gain is transmitted from the gain setting device 78 in accordance with the actual speed of rotation through the multiplying device

5 77 and integrator 79 based on the initial frequency set by the device 82 for setting the initial speed of the yarn. Information about the actual drive frequency of the bobbin holder shaft is supplied from

0 of the inverter controller 80 into the gain device 78. Then, the frequency of the drive of the reel shaft is determined using the inverter controller 80 based on the reference variable, which is fed to the inverter 4.

5 comprising means 26 for driving the reel shaft. In the winding device of the present invention, the drive means of the reel shaft are adjusted to maintain a constant peripheral speed of the package during

0 winding. Such adjustment is performed by comparing the registered rotational speed of the contact roller with a given theoretical or necessary rotational speed. That is, as the package diameter increases, the circumferential winding speed or package rotation speed increases, if the package rotation speed exceeds the required rotation speed, the frequency of the reel shaft drive inverter 14 immediately changes according to commands from

a controller 15 for reducing the speed of the drive means of the reel shaft, as a result of which the rotational speed of the contact roller 24 is reduced to the desired rotational speed and the constant winding speed is maintained.

Thus, the contact roller 24 rotates at a constant speed if the yarn is wound at a constant winding speed, for which the roller 24 and the reel 10 should be held in a non-contact state before winding starts, and the frequency and driving force on the drive means 20 of the contact roller It is necessary to adjust with the help of the drive inverter 25 so that the rotation speed of the roller corresponds to a given winding speed of the yarn. Therefore, it is sufficient that the specified drive force is constantly applied to the drive media 20 contact roller. No special adjustment is required.

As already indicated, the winding device of the present invention is characterized in that an independent drive system is used for the bobbin shaft and the contact roller. That is, the drive means of the reel shaft transfer the drive force required for winding the yarn, consisting of the force for rotating the reel and the package wound on the reel, and the force for pulling the yarn, and the drive means 20 of the contact roller transfer the drive force necessary for rotation of the contact roller 24, through the power transmission devices 21, 22 and 23. Therefore, when winding yarn at a constant winding speed, it is possible to maintain the minimum force of the transmission of rotation between the package 9 and the contact roller 24.

FIG. 7 showing the relationship between the peripheral speed of the contact roller 24 and the peripheral speed of the package 9 in the winding device of the present invention, yarn 5 is wound on the package 9 at a peripheral winding speed V2 via a contact roller 24 rotating at a peripheral winding speed VL Constant winding speed expresses the speed which corresponds to the following equation: The given circumferential speed is equal to the circumferential speed of the contact roller (V- |), equal to the circumferential winding speed (V2).

Theoretically, the winding speed does not change during the winding operation.

However, in a conventional winding device, slippage occurs between the contact roller and the package, which makes it impossible to correctly determine the peripheral speed of the contact roller.

In the winding device of the present invention, the slippage between the rollers and the package is reduced, and the circumferential speed Vi of the contact roller approaches the peripheral speed / 2 of the winding by eliminating the rotational transmission force between the contact roller 24 and the package 9. Thus, the yarn can be wound at a constant winding speed by indirectly controlling the peripheral speed of the contact roller 24.

An embodiment of the device for controlling the peripheral speed of the contact roller 24 is shown in FIG. 15. In this variation, ante a row of holes 13 is located on the peripheral surface of the contact roller 24. As shown in FIG. 16a and FIG. 166, a disk 51 mounted on the shaft 62 of the contact roller 24 using a washer 55 and a bolt 54 and having an annular row of holes 52 and a detector 53 to detect the presence of holes 52 can be used as a means of controlling the rotational speed. In this case, as a detector 53 can

5 use a photoelectric or magnetic sensor. Instead of holes, you can use a variety of labels such as protrusions of colored spots or grooves located at an equal angular distance on the face.

0 surface plates that can be detected using control means.

If the steady difference in speed caused by the slippage of the belts relative to the pulleys between the contact

5, the roller and its driving means are absent, instead of the peripheral speed of the contact roller 24, the peripheral speed of the driving means of the contact roller can be controlled.

0 Since the indicated means of controlling the rotational speed of the contact roller does not have any mechanical parts, in contact with other elements it is distinguished by high safety and reliability of work.

In the embodiment shown in FIG. 4, the required rotational speed is achieved by the parallel use of the integrated number of detected

0 holes and bills of the reference generator. However, a control system without a reference generator can be used. At the same time, the accuracy is somewhat reduced, but the system can be used in practical

5 conditions

In the embodiment of FIG. 4, a digital system was used as a control, but an analog system could be used to ensure good control.

The strength of the material forming the contact roller is a significant factor at a winding speed of 7000 m / min and more. For example, a centrifugal voltage of about 20 kg / m2 at a winding speed of 10,000 m / min acts on a contact roller, so viscous steel should be chosen as the material for the rollers.

The power consumption during the rotation of the roller depends on its surface area. For example, if a roller with a diameter of 100 mm and a length of 800 mm rotates at a peripheral speed of 10,000 m / min, the power consumption of the roller is approximately 3.8 kW. Although it is preferable to use a roller of smaller diameter to reduce power consumption, the roller of smaller diameter must rotate at a higher speed to obtain a predetermined speed of the circumferential roller. For example, a roller with a diameter of 100 mm must rotate at a speed of 32,000 rpm to obtain a peripheral speed of 10,000 m / min. Therefore, it is advisable to use a roller with a diameter of 80-120 mm, taking into account the service life of roller bearings.

Oil mist should be used to lubricate bearings.

It is preferable to use a high-speed three-phase induction motor as the driving means of the contact roller. The electric motor can be directly connected to the contact roller or the electric motor can be used without a rotor, which includes a contact roller. Further, the drive roller drive can be used with an air turbine instead of an electric motor.

The shape of the package obtained with a conventional winding device is shown in FIG. 8, and the shape of the package obtained with the winding device of the present invention is shown in FIG. 9. From the comparison of FIG. 9 and 8 it follows that the package of the present invention has a good shape, fewer protrusions as compared to the packaging of fig. 8, even when using a single winding angle.

The winding angle in the winding device is usually set in the range of 5-7 °. Packing with smaller winding angles forms a greater number of bumps. However, a good shape with a small amount of bumps can be obtained with a smaller winding angle according to the present invention. Further, the package may be wound at a winding angle of less than 5 ° by selecting appropriate operating conditions.

Therefore, the pickup speed can be reduced by reducing the winding angle. Thus, it is possible to increase the tension of the yarn at the point of returning the layout. In addition, you can extend the service life of the handler by reducing the speed of work. In particular, it is possible to increase the life of the yarn feeder and improve the quality of the yarn by reducing fluctuations in its tension.

As already indicated, since the drive forces of the shaft of the reel 11 and the contact roller 24 are required to obtain the desired

winding speeds are fed separately during winding, then the tangential force a (fig. 6) of the rotation transfer between the package and the contact roller is eliminated, which allows to get a package of good shape

without bulges. In addition, the contact pressure b of FIG. 6. which was previously required to obtain the rotational transmit force between the package 9 and the contact roller 24. The package can

Wrap only with the use of an insignificant contact pressure of 0.2 kg / cm necessary to keep the yarn wrapped around the cheese package. The following describes the folding

device with multi-track cam and method of winding with the help of this device.

A multi-track cam folding device used in the winding device of the present invention, FIG. 1 comprises a drive spreader in the form of a cylindrical cam 19 with an endless spiral guide groove, two slats 17 located along the cam axis, a yarn thread guide 18, one end of which engages with the guide groove and moves reciprocally along a pair of slats, driven the device 16 and the drive inverter (not shown). In this device, a cylindrical cam 19 is rotated by setting a frequency corresponding to a predetermined number of traverse movements for the drive inverter. The guide 18 transmits the traverse movement of the same 5.

The following describes a multi-track cam arrangement with reference to FIG. 10, 11a and 11b,

As shown in FIG. 10, this option

implementation of the multi-track cam used in the winding device of the present invention, the groove A of the multi-track cam begins at an arbitrary point on the peripheral surface

cam, for example at the first return point RI and passes through points 1, 2, 3 to the second return point R2. Groove A then passes through points 4, 5, 6 and 7 to the third return point Ra, Width 1, of the first reciprocating path, formed by the movement of the yarn feeder between point 1 and the third return point Ra. Further, groove A extends from the third return point Pz through points 8, 9, 10 and 11, the fourth return point R4 and points 12, 13 and 14 to the first return point RL. A width L.2 of the second reciprocating path is formed. In this case, groove A is a multi-track cam groove of two lanes. The width LI of the first reciprocating path is narrower than the width L2 of the reciprocating path by reducing the width at the second return point RZ and the width And at the third return point Ra. In other words, groove A is an endless spiral groove consisting of a plurality of inclined paths, such as paths from point 5 to point 6 or paths from point 9 to point 10, and many folded paths, such as paths from point 7 to point 8 and the trajectory from point 11 to point 12. The four return points Ri, R2, R3 and RA are located at different places along the axis of the cylindrical cam.

FIG. 11a shows the arrangement of the yarn feeder which moves reciprocally along the groove A, fig. 10. In connection with this, the yarn repeats the return movement at the points Ri, R2, Ra, and R4 while winding up the package. Therefore, the concentric part of the high-edge sections on the package wound with a double-track cam spreads out across the widths H and 2.

FIG. 11 b shows the location of the yarn feeder moving back and forth along the groove of the three-track cam. Taking into account the dimensions of the width C, and C, we can consider the following two combinations:

  2 1-3

or

Lt L.2 La

Although the number of tracks of a multidisk cam can be chosen arbitrarily, in practice it is advisable to use 2-4. Further, although the dimensions of the decreasing width And 12.1zi can be chosen arbitrarily, experiments performed have shown that each decreasing width must be greater than 2 mm to distribute the densified part along the peripheral plane of the package.

Referring to FIG. 13a and 13b describe the dispersion of the concentric part with a multi-track cam. As shown in FIG. 136, as the yarn speed in the axial direction of the package decreases to the point of yarn return, more yarn accumulates

0 on the front parts of the package compared with the middle part, which leads to the formation of areas with high sealed edges. If the number of yarn formed by the return movement of the yarn is denoted as a, and the number of yarn formed by its normal movement is (3, then in the range I, Fig. 13b, the amount a +/3 is formed. This is the compacted part of the yarn on a package of a known type.

0 FIG. 13a shows the compacted part

a package produced by a multi-track cam of FIG. 11a. In this case, the number of yarn 2 is collected in the range on the front parts of the package, position 41, and the number of yarn a / 1 + ft is collected in the section directed inward from the end part of the package, position 42. Therefore, since a / 2 + / 3 in the compacted part 42 is more than yarn a + / i / 2 in the compacted part 41, the compacted part 42 is formed as a protrusion of greater density compared to the density of part 41, and areas with high edges are dispersed.

5To receive a package without protrusions and

With such a yarn winding that does not lead to the formation of uneven brightness and uneven dyeing in the fabric, a combination should be used.

0 multi-track cam and spontaneous contact roller. For example, if the belt is wound at a speed of 5000 m / min and higher and protrusions are formed with a high density at a distance of 2 mm and more inwards from the ends of the package when using a winding device with a multi-track cam and a conventional friction-type contact roller two end surfaces of the package are similar t0 with together during the winding, making it impossible to continue.

If the package is obtained using a winding device with a multi-track cam and a spontaneous roller of the present invention, a square-shaped package can be obtained, Fig. 12b, and the yarn on such a package is of excellent quality, i.e. it almost does not form areas of low brightness, uneven coloring, and so on.

The following describes a new, freshly molded package of synthetic yarn, obtained using the specified winding device and method of its formation.

Under synthetic yarns used in the package under consideration, is meant synthetic yarn formed from a thermoplastic polymer having fiber-forming properties, eg, a thermoplastic polyester type or polietilentereftalta polibutilente- terephthalate, polyamide type thermoplastic poligeksametilendipamida and pol ikaproamida or thermoplastic poly-olefin such as polypropylene or polyethylene.

The synthetic yarn in the present invention is wound directly from the molding part of the molding machine without drawing and essentially has no torsions formed by rewinding.

Preferably, the synthetic yarn also has mechanical properties that allow it to withstand the process of weaving or spinning, since for these processes yarn is fed directly from the package. For example, typical synthetic yarns such as yarn made from polyethylene terephthalate, polyhexamethylene adipamide and polycaproamide preferably have a tensile strength of 3 g / den and a higher relative stretch ratio of 90% or less.

The cheese-like package of the synthetic yarn of the present invention is characterized in that the areas with the highest density are formed on the peripheral plane of the package displaced inwards from the two ends of the package in the direction of the central part.

FIG. 14a is a sectional view of a package 9 wound on a bobbin 10 according to the present invention. FIG. 14b shows the end portion 42 with the highest density, a protrusion formed by bent yarns. The diameter of this part is somewhat larger compared to other parts. The difference in diameter between the protrusion and other parts is preferably about 0.1 to 3 mm, more preferably about 0.1 to 1 mm. A suitable protrusion width in the axial direction of the package 9 depends on the winding angle of the yarn and the contact pressure between the package and the contact roller, but it is preferable that the protrusion width is 2-20 mm.

To eliminate the reduced brightness of the fabric made from the yarn package of the present invention, preferably

the formation of protrusions at a distance of 2 mm or more inward from the end planes of the package, more preferably 4 15 mm. If there are several protrusions in the peripheral plane at the ends of the package, it is not always necessary for each protrusion to be located inward from each end plane at the same distance, but it is preferable that each protrusion should be located at the same distance inward from each end plane to simplify the crosshead. If necessary, many protrusions can be used to further improve the shape of the package. However, to simplify the spreading mechanism, it is preferable to use two or four protrusions per package, i.e. one or two protrusions for each end portion of the package.

Since the protrusions of the largest diameter and the highest density are located inward from the ends 41, the tension on the ends 41 weakens, which leads to the elimination of lowered luminance on the fabric.

The package density increases dramatically from the center portion 43 to the ends 41 and is highest on the ridges 42. Preferably, the difference between the density of the center portion 43 and the ridges 42 is as low as possible, usually the difference may be 5-30%. The difference in density between the ends 41 and the protrusions 42 may be 5-20%.

The specific shape of the package is obtained at the beginning of the winding and is maintained until the end of this operation. Therefore, the package of the present invention maintains a good shape, starting from a small package, for example, weighing 1 kg, to a relatively large package, for example, weighing tens of kilograms.

The package freshly prepared according to the invention is also characterized in that the difference in shrinkage stress during hot drying of the yarn in the areas with the highest density in the package, i.e. on the protrusions, and the highest shrinkage voltage in the central areas is 40 mg / denier and less.

If this difference is 40 mg / denier or less, then it indicates that there will be a difference in luminance in the fabric being produced. This condition, set by a difference of 40 mg-denier or less, applies to each layer of the package. To further reduce the lower brightness, the voltage difference should be 20 mg-day or less, more preferably 15 mg / day and less.

When using the proposed coiler for winding polyester yarn with a double refraction of 0.08-0.14, an index of crystal perfection of 0.50 or less and a boiling water shrinkage ratio of 5% or less, the package obtained has excellent properties in shape, dyeing and resistance to reduced luminance in the fabric, as well as good dyeability at normal pressure and dimensional stability.

If the birefringence of polyester yarn is below 0.08. A yarn of such a package will not have sufficient mechanical properties, such as strength or relative elongation, to feed such yarn to a weaving or spinning machine without drawing or a similar process.

If the birefringence of polyester yarn is higher than 0.14, it is difficult to obtain the ease of dyeing, which is distinguished by yarn, is moldable with the help of high-strength molding systems.

Preferably, the birefringence should be 0.10-0.13 to obtain sufficient mechanical strength and good dyeability.

The crystal perfection index is a characteristic showing the structure of the crystal zone, as measured by the method described below. With a low crystal perfection index and mechanical properties are good, dimensional stability during heating is ensured. The index of perfection of a polyester fiber crystal of a package wound with the winding device of the invention is 0.50 or less, which ensures low shrinkage during heating.

To further improve the mechanical properties of polyester fiber, the crystal improvement index

should preferably be 0.30 or less.

Thus, the package of synthetic yarn obtained according to the present invention has good performance properties, providing uniform brightness and dyeing, and the device for forming the package has a simple design and allows to obtain a package with desired properties when working with low contact pressures between the contact roller and the bobbin holder.
