Description
Technical Field
The invention relates to the technical field of intelligent spinning equipment, in particular to a method and a system for improving spinning impurity removal performance through artificial intelligence.
Background
Rotor spinning machines have become the most mature technology, the widest application range and the larger economic and social effects in the novel spinning. Various impurities such as polypropylene fiber, hair and 'three-filament' are often generated in the spinning process, the generation of the impurities greatly reduces the product quality of the raw materials, and therefore the impurities in cotton slivers need to be removed in the spinning process.
At present, in the air suction type rotor spinning machine on the market, the carding and impurity stripping have two modes: the first is to use the centrifugal force of impurities to fall impurities freely. The carding roller and a vertical plane are arranged at a certain included angle alpha (alpha is less than 90 degrees), the impurity peeling direction and a horizontal plane form an angle alpha, and the impurity removal is called as free impurity removal by means of the comprehensive action of centrifugal force and gravity generated under the driving of high-speed rotation of the carding roller. The mode is longer to carry fibre transfer passageway to the rotor for the fibre obtains abundant straightening, and the resultant yarn uniformity is better, and the energy consumption is low. The second is an active gettering method. The carding roller is vertically arranged, the impurity stripping direction and the horizontal plane are in a parallel state, the impurity removal is realized by completely depending on airflow high negative pressure suction, the effective impurity separation can be also realized on various raw materials with larger impurity content, and the application range is wider.
However, the existing impurity removal scheme has the following defects:
1) When the free impurity falling mode is adopted, in the impurity separation process, light impurities with light weight, such as short fibers, are not thrown far away when being separated, are close to the fiber conveying area, are easy to be sucked back to the carding cavity after being accumulated in the stripping area under the action of fiber conveying negative pressure airflow, and are rolled and sucked back, so that the yarn breakage rate is increased, and the adaptability to regeneration raw materials with more short fibers and impurities is poor. When an active impurity suction mode is adopted, the impurities can be stripped along the horizontal plane only by requiring higher impurity suction negative pressure, and the number of the removed impurities is changed due to fine fluctuation of the impurity suction negative pressure, so that the variation of the thickness of finished yarns is larger; but also has the disadvantages of high energy consumption of the equipment and easy blockage of the gettering channel. That is to say, the existing rotor spinning machine carding and impurity stripping mode can not realize the complete improvement in the aspects of raw material adaptability, yarn quality consistency, low energy consumption and the like.
2) Regardless of free impurity falling or active impurity absorption, all cotton slivers entering the carding cavity are subjected to impurity removal and carding based on the same impurity removal flow, the impurity removal flow cannot be automatically adjusted according to fiber characteristics of cotton sliver raw materials, such as fiber length characteristics and cotton sliver compactness characteristics, and actually, the fiber lengths and the fiber densities on different cotton slivers are different. On one hand, along with the increase of the length of the fibers, the surface adhesive force formed by the fibers which are mutually staggered is increased, and the adhesive force and the wrapping force to impurities are also increased; on the other hand, for a more compact cotton sliver (the cotton fibers can be compacted under the action of pressure), the fiber density of the cotton sliver is relatively large, and the fibers are connected with each other more tightly, so that impurities are easily wrapped in the fibers and are not easily discharged. If all cotton sliver raw materials are subjected to an undifferentiated impurity removal process, energy waste can be caused or an impurity removal effect cannot be achieved.
Aiming at the dilemma in the market of the existing spinning machine, how to provide an intelligent impurity removing technical scheme which can be matched with the fiber characteristics according to the fiber characteristics of cotton slivers is a technical problem which needs to be solved urgently at present. Further, how to consider raw material adaptability, yarn quality consistency and low energy consumption is also a technical problem which needs to be solved urgently at present.

Examples
Referring to fig. 1, a flow chart of a method for improving the impurity removing performance of spinning by artificial intelligence is provided for the present invention.
The rotor spinning machine comprises a carding cavity provided with a carding roller, the carding cavity is communicated with a cotton sliver feeding channel and a fiber conveying channel, and an air supplementing channel and a carding cavity impurity discharging area are arranged below the corresponding carding cavity. During spinning, cotton slivers are sent into the carding cavity through the cotton sliver feeding channel to be carded, and fibers after being carded enter the interior of the rotor through the fiber conveying channel, then come out from the condensation groove, are drawn into the false twisting disc and are made into yarns.
In this embodiment, a sliver detector is provided corresponding to the sliver feeding passage. The cotton sliver detector is used for detecting the fiber length information of the cotton sliver when the cotton sliver is fed into the carding chamber through the cotton sliver feeding channel, and sending the fiber length information to the associated controller. And an air conveying mechanism is arranged corresponding to the air supplementing channel and is connected with the controller and receives the control of the controller. When the air is supplied to the carding cavity, the controller can acquire the air supplement intensity grade corresponding to the fiber length according to the fiber length information, and adjust the air conveying intensity of the air conveying mechanism according to the air supplement intensity grade, so that the self-adaptive impurity removal adjustment based on the cotton sliver fiber characteristics is realized.
Specifically, the method for improving the impurity removing performance of the spun yarn through artificial intelligence comprises the following steps:
s100, a cotton sliver fiber detection step, namely detecting the fiber length information of the cotton sliver by a cotton sliver detector arranged corresponding to the cotton sliver feeding channel when the cotton sliver is fed into the carding cavity through the cotton sliver feeding channel, and sending the fiber length information to a related controller.
The tampon detector is communicatively coupled to an associated controller. The communication connection may be wired communication or wireless communication. The preferred wireless communication mode that adopts makes the setting of controller more flexible.
Preferably, the tampon detector comprises a camera, an image recognition unit and a fiber property evaluation unit, and the step of detecting the fiber length information of the tampon by using the tampon detector may be as follows:
s110, shooting image data of the cotton sliver in the cotton sliver feeding channel through a camera, and transmitting the cotton sliver image data to an image recognition unit.
And S120, the image identification unit identifies the cotton sliver image data, acquires fiber arrangement information in the cotton sliver, and sends the fiber arrangement information to the fiber property evaluation unit.
The fiber arrangement information refers to the spatial distribution state of the fibers in the cotton sliver.
And S130, according to the fiber arrangement information, the fiber property evaluation unit evaluates the fiber length information of the cotton sliver based on a preset fiber property evaluation model.
The fiber property evaluation model may be, by way of example and not limitation, a mapping model of fiber arrangement information and fiber visibility property established based on fiber arrangement information of an existing common tampon, where the fiber visibility property information (a feature that can be visually observed) includes, but is not limited to, fiber color information, fiber length information, fiber linear density (thickness) information, fiber spacing information, and other parameters. Thus, based on the input fiber arrangement information, the corresponding fiber length information can be obtained through the fiber property evaluation model. Preferably, the fiber length information is represented by grades, and fibers below a preset standard length are classified into short fiber grades in the fiber property evaluation model, and fibers above the preset standard length are classified into long fiber grades in the fiber property evaluation model.
S200, impurity removing and carding: when the cotton sliver fed into the carding chamber is carded by the carding roller, air is supplied to the carding chamber through the air supply channel, and impurities or part of impurities fall into the impurity discharge belt through the impurity discharge area of the carding chamber under the action of self gravity and are discharged; the air supply device comprises a controller, an air supply channel, an air supply mechanism and a controller, wherein the air supply channel is provided with the air supply mechanism corresponding to the air supply channel, the air supply mechanism is connected with the controller and receives control of the controller, when air is supplied to the air distribution comb cavity, the controller can obtain an air supply strength grade corresponding to the fiber length according to fiber length information, and adjust the air supply strength of the air supply mechanism according to the air supply strength grade.
In specific implementation, the controller may obtain a mapping table of preset fiber length information and a wind compensation intensity level, and then obtain a corresponding wind compensation intensity level by searching the mapping table based on the received fiber length information. The mapping table may be established by a user, stored in the memory of the controller, or stored in a server connected to the controller.
The wind delivery intensity, i.e. the intensity of the output wind (or called wind force), is related to the wind speed. In this embodiment, the wind transportation intensity of the wind transportation mechanism may be divided into a plurality of levels, and one intensity level corresponds to one wind speed range.
The air delivery mechanism can comprise an air source and an air delivery pipeline, an output port of the air delivery pipeline is communicated with the air supplementing channel, an input port of the air delivery pipeline is connected with the air source, and the air source is preferably an air pump. When air is needed to be delivered, air is blown into the air delivery pipeline through the air pump, and the air close to the air delivery pipeline is output to the air supplementing channel to supplement air for the carding cavity.
The manner of adjusting the wind delivery strength of the wind delivery mechanism can be implemented by adjusting the flow rate of the air delivery of the air pump, for example, adjusting the rotation speed of the air pump (at this time, a driving machine of the air pump is connected with the controller and receives the control of the controller), or adjusting the opening of an air inlet valve of the air pump (at this time, the air inlet valve is connected with the controller and receives the control of the controller); the air delivery flow of the pipeline can also be adjusted by arranging an electromagnetic valve on the air delivery pipeline (at this time, the electromagnetic valve is connected with the controller and receives the control of the controller).
Preferably, a plurality of air supplement strength grades can be set corresponding to the fiber length of the cotton sliver, one air supplement strength grade corresponds to one fiber length range, and the fiber length ranges corresponding to the air supplement strength grades are not overlapped with each other. The air supplementing strength grade, the fiber length and the air conveying strength are in positive change, namely, the longer the fiber length is, the higher the corresponding air supplementing strength grade is, the larger the air conveying strength of the air conveying mechanism is, namely, the air supplement of the carding cavity is increased; conversely, the shorter the fiber length is, the lower the corresponding wind supplement intensity level is, and the smaller the wind conveying intensity of the wind conveying mechanism is. As the length of the fiber increases, the surface adhesion formed by the fibers which are mutually staggered also increases, and the adhesion to impurities and the wrapping force also increase; and through increasing defeated wind intensity, can increase the tonifying qi volume in the carding chamber unit time, stronger air current acts on the silver fibre, is convenient for silver fibre and silver fibre, silver fibre and impurity to separate.
In a preferred embodiment, two levels of air supplement intensity can be set, namely 0 level and 1 level; and when the detected fiber length information is the grade of long fibers, selecting the grade 1 wind supplement strength, otherwise, selecting the grade 0 wind supplement strength, namely selecting the grade 0 wind supplement strength for the grade of short fibers.
In another embodiment of this embodiment, considering that the fiber density of the tampon may also affect impurity removal — for a denser tampon (the cotton fibers may be compacted under the action of pressure), the fiber density of the tampon is also relatively high, and the fibers are connected with each other more tightly, so that the impurities are easily wrapped in the fibers and are not easily discharged — the wind-supplementing strength level may also be adjusted according to the fiber density of the tampon.
Specifically, the fiber density information of the tampon is detected by the tampon detector and sent to an associated controller. The fiber density of the tampon refers to the mass of the tampon per unit volume.
In one embodiment, the controller is capable of obtaining a corresponding wind compensation intensity level according to the fiber length information and the fiber density information of the combined cotton sliver, and adjusting the wind delivery intensity of the wind delivery mechanism according to the wind compensation intensity level, as shown in fig. 2.
In another embodiment, the controller may readjust the wind compensation intensity level corresponding to the fiber length based on the fiber density information, and adjust the wind delivery intensity of the wind delivery mechanism based on the adjusted wind compensation intensity level.
In particular, the cotton sliver detector may further include a weight measuring unit and a multi-view camera unit disposed on the cotton sliver feeding passage, the multi-view camera unit is connected to the image reconstruction processing unit, and the weight measuring unit and the image reconstruction processing unit are connected to the fiber property evaluation unit.

The weight measuring part measures the quality of the cotton sliver on the current cotton sliver feeding channel and sends the obtained quality value to the fiber property evaluation unit. By way of example and not limitation, the weight measuring part may include an electronic scale disposed in the sliver feeding passage, and the weight of the sliver passing through the weight measuring part is measured by the electronic scale when the sliver passes through the sliver feeding passage.
The fiber property evaluation unit obtains the volume value of the cotton sliver according to the three-dimensional size information of the cotton sliver and calculates the fiber density information of the cotton sliver by combining the volume value. The fiber density of the tampon is equal to the mass of the current tampon divided by its volume.
In order to further improve the impurity separation efficiency in the higher cotton sliver of closely knit degree, can also set up the jet hole and carry out the jet blast to the cotton sliver fibre. In specific implementation, preferably, a plurality of air injection holes are arranged on the surface of the carding roller in an array mode, and the air injection holes are connected with an air injection device; while the air jet is connected to the fibre property evaluation unit of the sliver detector.
The fiber property evaluation unit can compare the fiber density information of the cotton sliver with a preset fiber density threshold value, and sends an air injection instruction to the air injection device when the fiber density information of the cotton sliver is larger than the fiber density threshold value. And according to the air injection command, the air injection device controls the air injection holes to inject air when the cotton sliver is combed by the carding roller so as to improve the looseness of the cotton sliver and separate impurities from effective fibers.
Furthermore, considering that light impurities with light weight such as short fibers are close to the fiber conveying area and are easy to suck back to the carding cavity after being accumulated in the stripping area under the action of fiber conveying negative pressure airflow to generate turning and back suction, the impurity discharging structure combining free impurity falling and accurate impurity suction is further arranged. Specifically, the impurity removing area corresponding to the carding cavity is also provided with an impurity removing surface which is arranged obliquely downwards, and the impurity removing surface is provided with an impurity absorbing opening for absorbing impurities. In the embodiment, the impurity stripping surface and the horizontal plane are arranged in an angle of 60-70 degrees and inclined downwards, and an angle of 65 degrees is preferred.
When impurities are discharged, an impurity stripping channel which inclines downwards is formed at the lower part of the carding roller through the impurity stripping surface. Under the comprehensive action of the air injection and blast action of the air injection holes, the centrifugal force of the carding roller, the air supply supporting force and the self gravity, the impurity stripping channel can comprise an effective fiber area, a turning and back-suction area and a free impurity falling area from top to bottom. The long fibers in the effective fiber area are kept in the carding cavity to participate in yarn formation. The impurities in the turning back suction area are sucked into the impurity suction channel through the impurity suction port and discharged. The impurities in the free impurity falling area fall into the impurity discharging belt freely and are discharged.

The left side of the carding roller 120 is provided with a fiber transfer area 121 for transferring the carded sliver. The fiber transfer area 121 is arranged below the fiber conveying channel 140, and the cotton sliver passes through the fiber transfer area 121 after carding and is conveyed to the rotor through the fiber conveying channel 140.
The sliver feed channel 130 can include a feed horn, feed rollers, and feed plates. The cotton feeding horn can be formed by pressing plastic or bakelite, the section of a channel of the cotton feeding horn is gradually contracted into a flat shape from an inlet to an outlet, and the section of a cotton strip passes through the cotton feeding horn and is correspondingly changed along with the cotton strip. The inner wall of the cotton feeding horn is smooth, so that the friction resistance of the horn mouth to the cotton sliver is reduced, and the phenomenon that the uniformity of the cotton sliver is damaged due to accidental drafting is avoided.
The cotton feeding roller is preferably a groove roller which is held together with the cotton feeding plate and conveys the cotton sliver to the carding roller for carding by virtue of the positive rotation of the cotton feeding roller. In order to avoid the cotton sliver from diffusing to the two ends of the carding roller when being carded.

For the middle turning back suction area 161b, the area is mainly composed of light impurities, short velvet and other impurities (because the carding air supply holding force, the centrifugal force and the gravity are kept flat, part of the impurities are easy to be sucked back into the carding body, and accidental broken ends are caused). The gettering is mainly used for removing light impurities, short velvet and the like and preventing the light impurities, the short velvet and the like from being reversely absorbed back to the carding cavity after being rolled, so that the gettering negative pressure requirement is not high, and the low energy consumption is ensured. For the lower free impurity falling area 161c, the area is mainly composed of heavy impurities such as cotton neps, cotton seed hulls, short thread ends and the like, the unit volume weight is large, and the carding air supply supporting force is far smaller than the comprehensive acting force of centrifugal force and gravity, so that the heavy impurities and the heavy impurities freely fall into an impurity discharging belt to be discharged. The scheme is particularly suitable for the regenerated raw materials with more impurity content, heavy impurities, large impurities and the like in the impurities are freely discharged by combing centrifugal force, light impurities, short fibers and the like in the impurities are transferred and removed by impurity absorption, impurity turning and reverse absorption in an impurity discharge area of a combing cavity are eliminated, effective fiber yarn formation is reserved to the maximum extent, accurate impurity removal is realized, high yield is guaranteed, nep broken ends caused by impurity turning and reverse absorption are reduced, and the spinning suitability of the regenerated raw materials is improved.
