Example 1
The embodiment discloses a yarn treatment process, which comprises the following steps:
(1) opening, carding, drawing and roving the fibers to obtain roving;
(2) processing the rough yarn through a spinning process to obtain yarn;
(3) and (3) connecting the yarn which is output after the spinning process in the step (2) to a first yarn storage mechanism while the spinning process is carried out in the step (2), wherein the first yarn storage mechanism enables the yarn to be uniformly and tidily wound and arranged on the first yarn storage mechanism in a horizontal direction for storage in a continuously rotating mode, and meanwhile, the first yarn storage mechanism unwinds the yarn to a loom in a continuously rotating mode to be used as weft yarns.
In practical applications, the first thread storage mechanism may be provided separately (i.e. separately from the loom).
In some preferred embodiments, the first thread storage mechanism can adopt a weft accumulator structure in the existing loom, and the yarn is uniformly and orderly wound and arranged on the first thread storage mechanism in a horizontal direction in a continuous rotation mode to be stored for weaving of the loom without arranging other thread storage mechanisms.
In practical application, the spinning process mostly uses a spinning frame, and the spinning frame generally consists of a rear roller, a middle roller, a front roller, a roving spindle and a yarn guide hook. In practical application, in the step (2), the roving in the step (1) is hung on a roving spindle, and the roving sequentially passes through a horn mouth, a rear roller, a middle roller, a front roller, a yarn guide hook and is twisted to form yarn, so that the spinning process is completed. The twisting process uses a twisting forming mechanism. The process flow is prior art and is not described herein.
In practical application, if the total amount of the yarns on the first yarn storage mechanism is large, but the working power of the loom is fixed, and the phenomenon that the yarns are over-supplied is caused, the yarn breakage phenomenon is easily caused when the loom is used, the yarns which are output during the spinning process in the step (2) can be connected to a second yarn storage mechanism, the second yarn storage mechanism enables the yarns to be uniformly and tidily arranged on the second yarn storage mechanism along the horizontal direction in a continuous rotation mode, and meanwhile, the second yarn storage mechanism enables the yarns to be unwound to the first yarn storage mechanism in a continuous rotation mode. The plurality of thread storage mechanisms are arranged to play a role in thread supply and buffering, and the phenomenon that the machine is blocked and stopped due to the fact that weft yarns on the loom are wound mutually due to excessive weft yarns is avoided.
In a preferred embodiment, the yarn amount on the first yarn storage mechanism needs to be detected in real time, and the working efficiency of the spinning frame is adjusted according to the real-time detection result. Specifically, when the yarn quantity on the first yarn storage mechanism exceeds a certain numerical value (for example, a preset maximum yarn quantity value), the working efficiency of the spinning machine is adjusted, the yarn output quantity of the spinning machine is reduced, and the yarn output quantity of the spinning machine is matched with the weaving efficiency of the loom; when the yarn quantity on the first yarn storage mechanism is less than a certain value (for example, a preset minimum yarn quantity value), the working efficiency of the spinning machine is adjusted, the yarn output quantity of the spinning machine is increased, and the yarn output quantity of the spinning machine is matched with the weaving efficiency of the loom.
In practical application, when the yarn in the step (3) has a preset defect, the step (2) and the step (3) are stopped at the same time, and the yarn with the defect in the step (3) is cut off and then connected to the first yarn storage mechanism. This kind of setting mode, if defects such as uneven thickness, knot appear in the yarn, should amputate the defect line segment after discovering to connect the yarn breakpoint back, the yarn directly convolutes on first yarn storage mechanism, makes the even interval of yarn convolute above that, then connects the loom, uses as the woof, thereby guarantees the quality of follow-up product that contains this yarn, still can guarantee the normal work of loom, prevents that the phenomenon such as part structure card of loom that the end of a thread winding is piled up and lead to from taking place.
In the yarn processing technology disclosed by the invention, the yarn output from the spinning machine body is directly connected by using the yarn storage mechanism which works in a continuous rotation mode on the loom, and the yarn is uniformly wound and arranged on the yarn storage mechanism in the horizontal direction and is unwound into the loom in the same mode, so that the yarn can be continuously conveyed after being generated from the spinning machine body in the whole technological process until the yarn is used in the loom. Compared with the traditional yarn processing mode, the invention does not need to perform spooling storage on the yarn generated on the spinning frame body to form a large package, and can be used for the loom only after workers place the yarn of the large package on the yarn storage frame, thereby not only omitting the spooling operation step, but also simultaneously performing the yarn generating step and the weaving step, and improving the production efficiency of the loom. And a bulky yarn storage rack is not required to be arranged beside the loom in a factory, and large package yarns are not required to be carried manually, so that the machine cost and the labor cost are reduced, the production cost is reduced, the production efficiency is increased, and the sustainable development is facilitated.
Example 2
As shown in fig. 1, the present invention further discloses a yarn processing device, which includes a spinning unit, a first yarn storage mechanism and a control system (which may be a PLC controller or a single chip microcomputer, and is not described herein again), wherein the spinning unit includes a spinning frame body 1 and a twisting forming mechanism 2. The roving drawn out from the spinning frame body 1 passes through the twisting forming mechanism 2 to form yarn; in the spinning process, the first yarn storage mechanism enables the yarns which are output after spinning to be uniformly and tidily wound and arranged on the first yarn storage mechanism in the horizontal direction for storage in a continuous rotation mode, and meanwhile, the first yarn storage mechanism enables the yarns to be unwound to the loom 3 in a continuous rotation mode to be used as weft yarns. In order to enable spinning and weaving to be performed simultaneously, in this embodiment, the spinning frame body 1, the twisting forming mechanism 2, the first thread storage mechanism and the loom 3 are all electrically connected to the control system, and the control system is configured to control the spinning frame body 1, the twisting forming mechanism 2, the first thread storage mechanism and the loom 3 to start and stop simultaneously.
Further, the spinning frame body 1 comprises a bell mouth (not shown in the figure), a rear roller 11, a middle roller 12, a front roller 13, a roving spindle 14 and a yarn guide hook 27, wherein the rear roller 11, the middle roller 12 and the front roller 13 are all driven by a servo motor (not shown in the figure).
The device disclosed by the invention also comprises a second wire storage mechanism, wherein the second wire storage mechanism is electrically connected with the control system; the yarn which finishes the spinning process and is output is connected to the second yarn storage mechanism, the second yarn storage mechanism enables the yarn to be evenly and tidily arranged on the second yarn storage mechanism along the horizontal direction in a continuous rotation mode, and meanwhile, the second yarn storage mechanism enables the yarn to be unwound to the first yarn storage mechanism in a continuous rotation mode.
In the preferred embodiment, both the second storage mechanism (for convenience of description, hereinafter referred to as the second storage 5) and the first storage mechanism (for convenience of description, hereinafter referred to as the first storage 4) are storage devices.
In practical application, when the yarn is wound on the first weft accumulator 4 and the second weft accumulator 5, because the winding hubs (not marked in the figure, also called as rollers, horizontally arranged, and the structure is the prior art) of the weft accumulators move in a rotating mode, the yarn is uniformly and loosely arranged when wound on the winding hubs, and the yarn do not interfere with each other, so that the yarn can be conveniently unwound. The storage type yarn storage method can store a large amount of yarns relative to the winding of the cheese, and the winding arrangement among the yarns is not tight. In practical application, if the winding speed of the winding hub in the weft accumulator is greater than the production speed of the loom 3, a large amount of yarns are accumulated outside the loom 3, so that a plurality of weft accumulators are needed to play a role in yarn supply and buffering, and the phenomenon that the machine is blocked and stopped due to the fact that the wefts on the loom 3 are wound with each other due to too many wefts is avoided. The invention is provided with the weft accumulator as a yarn storage mechanism, realizes the effect that the yarn can be quickly unwound so as to be quickly conveyed forwards (providing the yarn for the loom 3), and can effectively adjust and control the state of the yarn B to ensure the product quality. The invention utilizes the weft accumulator which works in a continuous rotation mode in the weaving machine to directly connect the yarns output from the spinning machine body, and the yarns are uniformly wound and arranged on the yarn storage mechanism along the horizontal direction and are unwound into the weaving machine in the same mode, so that the yarns can be continuously conveyed after being generated from the spinning machine body in the yarn processing device disclosed by the invention until the yarns are used in the weaving machine. Compared with the traditional yarn processing mode, the invention does not need to perform spooling storage on the yarn generated on the spinning frame body to form a large package, and can be used for the loom only after workers place the yarn of the large package on the yarn storage frame, thereby not only omitting the spooling operation step, but also simultaneously performing the yarn generating step and the weaving step, and improving the production efficiency of the loom. And need not to set up bulky storage creel by the loom in the mill, need not the big package yarn of manual handling to reduce the restriction condition to indoor space size such as factory building, not only improved the production efficiency of loom, not only reduced machine cost and cost of labor moreover, manufacturing cost reduces, and production efficiency increases, is favorable to sustainable development.
In practical application, as shown in fig. 2, the twisting and forming mechanism 2 includes a bracket 21, a transmission rod 22, a circular ring 23, a snap ring 24 and a driving motor 25, the transmission rod 22 (through a bearing structure, not shown in the figure) is installed on the bracket 21, the transmission rod 22 is a horizontally placed "T" shaped structure, the head of the transmission rod 22 is connected to the inner walls of the two sides of the circular ring 23, and the other end of the transmission rod 22 is connected with the driving motor 25 through a belt transmission mechanism; the surface of the circular ring 23 is provided with a convex part (not marked in the figure), the convex part extends along the circumferential direction, the inner wall and the outer wall of the convex part are both provided with a step position 26, the step position 26 extends along the circumferential direction, the snap ring 24 is detachably connected on the step position 26, and the driving motor 25 is used for driving the transmission rod 22 to rotate on the bracket 21; after the roving passes through the clamping ring 24 and the circular ring 23, the roving is wound at the tail of the transmission rod 22, and when the transmission rod 22 rotates, the clamping ring 24 is driven to move along the direction of the step position 26, so that the roving is twisted. Specifically, before starting up, after making roving one end pass snap ring 24 and ring 23, twine at the transfer line 22 afterbody, when driving motor 25 drive transfer line 22 rotatory, can drive snap ring 24 rotatory for ring 23, but because snap ring 24 has the friction on ring 23, make the rotational speed of snap ring 24 be less than the revolution of ring 23, utilize the speed difference thereby to realize the twisting to the roving, specifically make the direction of twist of twisting device upwards transmit the principle (the yarn is drafted) in the spinning technology, make the roving come out the back by the nipper of front roller. The snap ring 24 and the working mode thereof in the application are similar to the steel collar type twisting structure on the existing spinning frame, but the application designs a new twisting mechanism aiming at the application, and the twisting mechanism has the advantages of exquisite structure, convenient use and independent disassembly and assembly.
In this embodiment, the yarn twisting machine further includes a quality detection device (not shown), an automatic yarn cutting machine (not shown), and an automatic yarn splicing machine (not shown), wherein the quality detection device, the automatic yarn cutting machine, the automatic yarn splicing machine, the spinning frame body 1, the twisting forming mechanism 2, the first yarn storage mechanism, and the loom 3 are all electrically connected to the control system, and certainly, the second yarn storage mechanism is also electrically connected to the control system (as shown in fig. 3); the quality detection device is used for acquiring yarn quality defect information, the control system controls the spinning machine body 1, the twisting forming mechanism 2, the first wire storage mechanism and the loom 3 to stop simultaneously according to the yarn quality defect information, and then sequentially controls the automatic wire cutting machine and the automatic wire connecting machine, wherein the automatic wire cutting machine is used for cutting off yarn defect line sections, and the automatic wire connecting machine is used for connecting broken wires. The spinning frame body 1 and the loom 3 have the same control system, and control spinning and weaving to be carried out synchronously, for example, in the spinning step or the weaving process, the spinning and weaving can be stopped at the same time when a problem occurs, so that the spinning and weaving integration is realized. The quality detection device can be a tension sensor which detects the tension of the advancing yarn, the control system controls the automatic yarn breaking machine to cut the yarn under the condition that the control system judges that the yarn is abnormal according to the detection result of the yarn monitoring device or the tension sensor, and yarn breakpoints can be connected through the automatic yarn connecting machine, so that the phenomenon that the defective yarn is directly used for weaving is effectively prevented. In this embodiment, the two yarn storage mechanisms are provided to facilitate monitoring of yarn quality, and when a defect is detected in the yarn before the yarn is fed into the loom, the yarn between the first yarn storage mechanism and the second yarn storage mechanism can be cut and connected. If the yarn between the first yarn storage mechanism and the loom 3 is detected and cut, the motion state of the yarn fed into the loom 3 is seriously affected, for example, the tension value of the yarn is changed, so that the product quality is difficult to ensure, and the operation of feeding the connected yarn into the loom 3 is complicated, which is not favorable for improving the production efficiency.
In practical use, when the spinning efficiency is higher than the weaving efficiency, that is, a large amount of yarn is accumulated on the weft accumulator and is not sent to the loom 3 for weaving, the above situation can be prevented by respectively controlling the spinning efficiency of the spinning unit and the weaving efficiency of the loom 3, therefore, in the embodiment, the spinning device further comprises a yarn quantity detection device which is electrically connected with the control system, the yarn quantity detection device is used for detecting the real-time yarn quantity value of the yarn stored on the first yarn storage mechanism in real time and sending the real-time yarn quantity value of the yarn stored on the first yarn storage mechanism to the control system, and the control system adjusts the spinning frame and/or the working efficiency of the loom 3 according to the real-time yarn quantity value. Specifically, the real-time yarn quantity value of the yarn stored in the first yarn storage mechanism is compared with a preset maximum value, and if the real-time yarn quantity value of the yarn stored in the first yarn storage mechanism is larger than the preset maximum value, the efficiency of a spinning machine is reduced, so that the output yarn quantity is reduced, or the efficiency of a loom is improved, and the consumed yarn quantity is increased; if the real-time yarn quantity value of the yarn stored in the first yarn storage mechanism is smaller than the preset minimum value, the efficiency of the spinning machine is improved, the output yarn quantity of the spinning machine is increased, or the efficiency of the weaving machine is reduced, and the consumed yarn quantity of the spinning machine is reduced.
In practical application, when the number of the yarns on the weft accumulator is recovered to the preset value range (namely between the minimum value and the maximum value), the control system controls the loom 3 to recover to normal work.
In some preferred embodiments, the yarn quantity detection means may be an electronic counter. Since the winding hub on the weft accumulator is continuously rotated for winding, and a yarn segment with a preset length can be wound on the winding hub in a single rotation, the number of rotation turns of the winding hub on the weft accumulator is monitored and acquired by using an electronic counter, so that the number of yarns on the winding hub can be calculated by a person skilled in the art.
In other preferred embodiments, the yarn quantity detecting device may employ a weighing device, for example, to weigh the first yarn storage mechanism in real time, i.e., to calculate the yarn quantity value based on the density of the yarn.
