Technical Field

The invention relates to the technical field of composite yarn spinning, in particular to a full-automatic intelligent control method and system for fasciated yarns in rotor spinning.

Background

The wrapped yarn is also called covering yarn, which is a composite yarn. The wrapping yarn is composed of two kinds of fibers, namely filament yarn wrapped on a short fiber (wool type or cotton type) yarn core or short fiber wrapped on a filament yarn core, and the wrapping yarn wraps the core yarn in a spiral mode, and is characterized by uniform evenness, bulkiness and fullness, smooth yarn with less hairiness, high strength and less broken ends. Of course, there are also wrapped yarns composed of three types of fibers, such as wrapping a staple fiber around a filament to form a core and then wrapping another filament; or wrapping a filament inner core with a filament outer core, and then wrapping with short fibers. The wrapping yarn has the characteristics of each component due to the special structure. At present, the methods for spinning fasciated yarns are many, and mainly comprise a hollow spindle method, an air vortex method, a self-twisting fasciated yarn and a rotor spinning fasciated yarn.

For rotor-spun fasciated yarns, the spinning process must be resumed after the yarn breaks on the rotor spinning machine, which results in a piecing process. On one hand, the broken ends not only influence the production efficiency and the product quality, but also form the strand winding roller, so that the components of the textile machine are easily damaged. Therefore, it is extremely necessary to detect the yarn breakage. On the other hand, the joint yarn has defects in appearance and strength as compared with the normal yarn. Many expensive machines use special piecing methods to reduce these drawbacks-such as pneumatic methods, where the initial feed of fiber is removed so that the feed of stock is resumed once the broken fiber has been removed, but this solution is technically difficult to achieve and is mechanically complex and costly.

How to spin the fasciated yarn based on the rotor, provide a full-automatic intelligent control scheme easy operation, low cost, broken end control accuracy height and connect high quality, be the technical problem that needs to solve at present.

S400, during the process of leading out the package of the wrapping yarn, the monofilament or yarn fed by the external feeding mechanism is wound on the surface of the core yarn to form the wrapping yarn.

In step S100, the step of performing the end breakage control by the controller according to the yarn breakage signal may specifically be as follows:

and S110, receiving a yarn breaking signal.

And S120, judging whether the yarn is broken end of the rotor spinning machine or monofilament or yarn broken end of an external feeding mechanism according to the sending object of the yarn breaking signal.

S130, when the yarn breakage of the rotor spinning machine is judged, a yarn breakage signal is sent to the controller through the first yarn detector, the controller commands the first yarn leading motor and the feeding motor of the spinning unit to stop working, the yarn supporting rod lifts the first yarn drum, and commands the cutting mechanism of the peripheral feeding mechanism to break monofilaments or yarns and the second yarn leading motor to stop working at the same time, and the yarn breakage control is completed.

Referring to fig. 2, a combination mechanism of a rotor spinning machine spinning unit 100 connected with an external feeding mechanism 200 is illustrated.

The rotor spinning machine spinning unit 100 comprises a first bobbin 1, a yarn supporting rod 2, a winding roller 3, a yarn guide nozzle 4, a tension bow 5, a first yarn detector 6, a first yarn guiding motor 8, a yarn guiding pipe 9, a rotor 11, a fiber conveying channel 12, a carding roller 13, a feeding motor 14 and the like, and all the structures are connected with a controller and receive the control of the controller.

The peripheral feeding mechanism 200 comprises a second bobbin 15, a guide ring 16, a second yarn guiding motor 18, a cutting mechanism 19, a second yarn detector 20, a monofilament or yarn feeding channel 21 and the like, and all the structures are connected with and receive the control of the controller.

The first yarn detector 6 and the second yarn detector 20 are in communication connection with the controller, the first yarn detector 6 collects yarn breakage signals of the rotor spinning machine spinning unit 100 and sends the yarn breakage signals to the controller, and the second yarn detector 20 collects monofilament or yarn breakage information of the external feeding mechanism 200 and sends the monofilament or yarn breakage information to the controller. The controller can control the breakage according to the yarn breakage signal, namely control a first yarn leading motor and a feeding motor of the spinning unit to stop working, lift the first yarn drum by the yarn supporting rod, and simultaneously control a second yarn leading motor of the peripheral mechanism to stop working. The controller is also capable of controlling the structures of the spinning unit 100 and the external feeding mechanism 200 to re-enter the working state after acquiring the piecing command.

Specifically, first, when the yarn is broken, the controller performs the breakage control. If the yarn is broken end of the rotor spinning machine, the first yarn detector sends a broken yarn signal to the controller, the controller commands the feeding motor of the spinning unit to stop working and the yarn supporting rod to lift, and simultaneously commands the cutting mechanism of the external feeding mechanism to break monofilament or yarn and the second yarn leading motor to stop working, so that the broken end control is completed. If the single yarn or the yarn of the external feeding mechanism is broken, the second yarn detector sends a yarn breaking signal to the controller, and the controller commands the feeding motor of the spinning unit to stop working and the yarn supporting rod to lift up, and commands the second yarn leading motor of the external feeding mechanism to stop working at the same time, so that the broken end control is completed.

Then, the controller fixes the length of the fasciated yarn of the first yarn drum into a yarn leading pipe of the spinning unit after fixing the length of the fasciated yarn of the first yarn drum and the length of the monofilament or yarn of the external feeding mechanism, and simultaneously fixes the length of the monofilament or yarn of the external feeding mechanism into a monofilament or yarn feeding channel.

And triggering a joint button and sending a joint instruction to the controller. According to the joint instruction, the controller controls a feeding motor 14 of the spinning unit to start to work, cotton slivers are fed, the cotton slivers are combed through a carding roller 13, the combed fibers enter a rotor 11 through a fiber conveying channel 12, the fibers in the rotor 11 are condensed to form strands and then are twisted to form yarn strips to form rotor yarns 10, and the rotor yarns 10 are used as core yarns of the fasciated yarns 7; at the same time of feeding cotton sliver, controlling the first yarn leading motor 8 to reverse and sink the seed yarn into the rotor 11 to joint with the core yarn, and controlling the first yarn barrel 1 to fall down to complete the joint action of the spinning unit; then a second yarn leading motor 18 of the external feeding mechanism works to feed the monofilament or yarn 17 on the second bobbin 15 into the rotor 11 of the spinning unit.

The mode of triggering the joint button can be based on a triggering instruction of a user, or can be based on a preset condition of a system, and the joint button is automatically triggered when the condition is met. By way of example and not limitation, the preset condition may be, for example, when the wrapped yarn collected from the first bobbin is inserted into the yarn introducing tube and the monofilament or yarn of the external feeding mechanism is inserted into the monofilament or yarn feeding passage, or 10 seconds after the insertion operation is completed.

During the process that the yarn (fasciated yarn) in the spinning cup 11 is led out of the package through the yarn-leading tube 9, the monofilament or yarn 17 fed by the external feeding mechanism is automatically wound on the surface of the core yarn (namely the rotor yarn 10) to form the fasciated yarn 7.

The input end of the conveying pipeline 32 is connected with the conveying pipeline component supply cavity 31, the output end of the conveying pipeline 32 is connected with the rotating cup 11, and the driving mechanism 312 is connected with the controller 400 and receives the control of the controller 400.

After the controller 400 receives the functional component adding instruction, it can control the driving mechanism 312 to start generating the air flow or the injection force to make the functional component raw material enter the interior of the rotating cup 11 through the conveying pipeline 32. When the monofilament or yarn 17 is wound around the core yarn, the functional component acts on the core yarn and/or the outer layer winding of the wrapping yarn and is fixed.

Preferably, the driving mechanism 312 may include a drainage fan and a lift fan, the drainage fan may be disposed at a connection point of the component supply chamber and the delivery pipe, and the lift fan may be disposed on an inner wall of the component supply chamber. The air flow transmitted to the rotating cup is generated by the drainage fan, the functional components are driven by the lifting fan to lift so that the functional components enter the rotating cup along with the air flow, and a distribution area with the functional components is formed in the rotating cup. At this time, the component supply chamber 31 is provided with a vent 313, the vent 313 functions as an air inlet and also functions as an inlet for the supplementary functional component 311, and the size of the vent 313 is adjustable.

For example, the wind generator is configured to apply charges to air and accelerate the flow of gas, including the flow of particles in the gas, by the principle that like charges repel each other.

It should be noted that the drainage fan can be replaced by a blower or an air pump, and the position of the drainage fan is preferred and not limited. Any aerodynamic structure capable of accelerating the air flow of the chamber and directing the air flow to the output end of the delivery line may be used in the component supply chamber 31 as a drive mechanism to provide the air flow to the delivery line 32. Furthermore, any structure capable of forming gas flow is expected to be applied to the driving mechanism of the present invention, and the specific principle and structure are not limited. The aerodynamic structure can accelerate the circulation process of the gas in the working space and/or the functional components carried by the gas in the working space.

And a traction part is arranged corresponding to the output end of the conveying pipeline, and the output end and the traction part of the conveying pipeline are arranged on two sides of the core yarn, for example, the output end of the conveying pipeline is positioned in the lower area of the core yarn, and the traction part is positioned in the upper area of the core yarn. The traction part is provided with a traction electrode or a traction electret to adsorb charged components to move towards the direction of the traction part, and the moved charged components are twisted and/or wound by outer layer winding yarns to be compounded on the wrapping yarns when passing through the core yarns.

In this embodiment, the electrostatic generator is capable of generating and discharging a net charge substance. In the air, the electrostatic generator can be excited by high voltage to generate substances with positive or negative net charges. The specific structure of the electrostatic generator is not limited, for example, by arranging an anion generator at the outlet of the conveying pipeline, electrons excited by the anion generator are attached to the functional component when encountering the functional component, namely powder particles or fibers, in the conveying pipeline, so that the functional component has a net charge property to form a charged component. To facilitate the discharge of the net charged matter, the electrostatic generator may also be provided with an electrostatic arrangement, such as a frame structure defining the distribution of the net charged matter, or a conduit for conducting the net charged matter, or other similar structures.

In one embodiment, the electrostatic generator may include a discharge electrode, the discharge electrode is mounted on the conveying pipeline, the end of the discharge electrode corresponds to the inner cavity of the conveying pipeline, the discharge electrode is excited by high voltage to generate a substance with a net charge of positive or negative charge and form a charge releasing region in the inner cavity of the revolving cup, and the functional component adsorbs the net charge substance to form a charged component when passing through the charge releasing region.

As a typical embodiment, the charge discharging part includes an electrostatic generator electrically connected to a power source. The static generator is in communication with the controller and receives control of the controller.

The power supply is used as a power supply structure of the static generator, and can be a storage battery structure, an external power supply or a wireless power supply structure. In the present embodiment, a secondary battery is preferably used.

The electrostatic generator may specifically include an electrode wire and a discharge electrode, and the plurality of discharge electrodes vertically arranged are connected through the electrode wire. After triggering the charge adsorption command, the controller may start the static and dynamic generator, and the high voltage is excited by the discharge electrode to produce a net charge material. The discharge electrode is preferably a discharge needle with a tip, the tip size of the discharge needle is micrometer, and a strong electric field is formed by the tip to improve the high-voltage discharge effect. By way of example only, the discharge needles preferably have a diameter of 20 microns and a length of 500 microns. The discharge needle can be manufactured by using a high-aspect-ratio dry etching process on a silicon substrate material and electroplating metal copper on both sides. Because the size of the tail end of the discharge needle is in the micron order and the metal distances of the two sides are very close, a high-voltage discharge effect can be formed at the tail end of the discharge needle only by using a low-power supply.

Referring to fig. 7, a drawing portion is provided corresponding to the output end of the delivery pipe, in fig. 7, the output end of the delivery pipe is located at the lower region of the core yarn (rotor yarn 10) and communicates with the inside of the rotor 11, and the drawing portion 600 is located at the upper region of the core yarn (rotor yarn 10). The drawing part 600 is provided with a drawing electrode or a drawing electret to attract the negatively charged component 311 'to move in the direction of the drawing part 600, and the moving charged component 311' is twisted and/or wound by the outer layer winding yarn while passing through the core yarn (rotor yarn 10) to be combined with the wrapping yarn 7 to form the multifunctional wrapping yarn.

In one embodiment of this embodiment, the traction electrode of the traction portion 600 includes a metal pole piece and an electrical path, the electrical path can be connected to a controller, and the controller can control the electrical path to be powered on or powered off. After the power-on circuit is powered on, the metal pole piece forms an electrode opposite to the net charge substance, so that the charged component is subjected to a downward electric field force, and moves towards the traction part under the action of the electric field force.

The metal pole piece can be made of metal aluminum foil, for example. By way of example and not limitation, for example, a discharge electrode of the electrostatic generator is excited by a high voltage to release electrons, the excited electrons are discharged corresponding to the output end of the conveying pipeline, and a negatively charged component is formed after encountering a functional component in the conveying pipeline; and the aluminum foil of the traction electrode is electrified to form a positive electrode, the negatively charged component in the output end is attracted to move to the position of the aluminum foil, and the negatively charged component is twisted and/or wound by the outer layer winding yarn to be compounded on the wrapping yarn when passing through the core yarn.

In another embodiment, the traction portion employs a traction electret as the charge-adsorbing structure. Specifically, the pulling electret is an electret having a counter electrode, and a charge property opposite to the excited net charge substance is formed by the electret, so that the attracted charged component moves in the direction toward the pulling portion. In this method, a charge property opposite to the net charge substance is formed in the traction portion by utilizing the long-term charge storage property of the electret, and the net charge substance is moved to the traction portion, so that it is not necessary to provide a wiring.

Preferably, the traction part is provided with at least two groups of traction electrodes or traction electrets, each group of traction electrodes or traction electrets comprising one or more traction electrodes or traction electrets. The two groups of leading electrets are arranged as an example, the leading electrets can comprise a first group of traction structure and a second traction structure which are isomorphic (same in structure), the first group of traction structure and the second traction structure can be connected through a shifting mechanism, and the positions of the first group of traction structure and the second traction structure can be adjusted through the shifting mechanism, so that at any moment, one group of traction structure is positioned at an effective adsorption position to play an adsorption role, and the other group of traction structure is in an idle standby state.

When the traction electrode or the traction electret group which plays a role of adsorption at present needs to be cleaned, the traction electrode or the traction electret is driven to leave from the effective adsorption position through the shifting mechanism, and meanwhile, a new traction electrode or a new traction electret group is driven to enter the effective adsorption position. Therefore, when one group of the traction structures is polluted by the charged components and cannot effectively adsorb the charged components, the other group of the traction structures which are not polluted and are in an idle standby state can be adjusted to the effective adsorption position to continuously play an adsorption role. Then, the contaminated group of traction structures is cleaned, and after the charged components are removed, the traction structures are put into an idle standby state.

The displacement mechanism may be a mechanism that adjusts the position of the traction structure based on horizontal movement, or may be a mechanism that adjusts the position of the traction structure based on rotational movement.

Preferably, a cleaner is arranged corresponding to the traction electrode or the traction electret set, and in the displacement process of the traction electrode or the traction electret set, the cleaner is in contact with the polluted first group traction structure, and the cleaner cleans the charged components adsorbed on the first group traction structure to finish the cleaning of the first group traction structure.

Preferably, the cleaning device may further include a component supply chamber connected to the component adding unit 300 through a recycling line, so that the cleaned charged component can be recycled to the component supply chamber through the recycling line after being de-charged. The charged component can be removed by neutralization, such as generating an air flow with ions by an ion blower, and the air flow blows the negatively charged component to neutralize the static electricity, so that the component is neutral; it is also possible to bring the components to neutrality by contacting the charged components with a metal mesh to conduct away the net charge.
