Description

A single winding device of an automatic loose winding machine

technical field

The invention relates to the field of textile machinery equipment, in particular to a single winding device of an automatic loose winding machine.

Background technique

With the enhancement of people's aesthetic awareness and the improvement of living standards, high-grade yarn-dyed products are becoming more and more popular. Not only real silk, chemical fiber silk, rayon, blended yarn and cotton yarn can also be made of dyed silk. The most economical dyeing process of colored yarn dyeing is direct dyeing with bobbins, so it is widely used. Generally, before dyeing the yarn bobbin, it is necessary to wind the purchased gray yarn or bobbin into a "loose bobbin" suitable for bobbin dyeing for the next process, so the demand for loose bobbins is increasing day by day. How to produce qualified loose bobbins and packages to facilitate uniform dyeing of bobbins has become a problem that people need to start solving.

Existing automatic loose winding machines generally include a power device composed of a motor and a conveyor belt, a winding device assembled by an even number of identical single winding devices by connecting control components, and a feeding device, electrical and mechanical and other host control devices and racks for installing the above devices, etc.

The loose-type winding machine generally has the following requirements for the winding bobbin used in bobbin dyeing: 1. During winding, the bobbin needs to be fixed in length, soft and soft, and uniform in winding density; 2. The winding angle must consider the gap between yarn layers. There is a large gap, so a slightly larger winding angle is used to make the dyeing liquid penetrate into the yarn layer smoothly; 3. The edge of the package should be soft and uniform, commonly known as loose edge package; 4. It is required not to produce any overlapping, edge removal, Cobwebs and other forming imperfections for even dyeing and light unwinding.

The single winding device of the existing automatic loose-type winding machine has the following defects in use: 1. The main work is to realize the anti-folding design when winding, and the appearance structure of the loose-type bobbin itself is also affected. One of the reasons for the smooth completion of the dyeing process is that the edge yarn loops of the parallel or rectangular loose bobbins are too tight, which is easy to cause tight edge bobbins and uneven dyeing; Yarn self-stop requirements, the existing device is more complicated, and the cost is higher; 3. The anti-folding design during winding is more complicated, and the cost is higher; 4. The lateral reciprocating motion of the yarn is not separated from the winding motion during use. Instead, the grooved drum is used not only as a yarn guide, but also as a friction roller to drive the circular motion of the yarn drum, and the groove of the grooved drum is used to guide the reciprocating movement of the yarn, which will easily lead to the disadvantages of overlapping yarns and fluff; 5. Between the components The connection design between them is not reasonable enough, and the energy consumption is high during use.

In view of this, the inventor combined his years of experience in spinning machinery to conduct long-term research on the defects in the above-mentioned technical field, and this case came about.

A movable pull rod 43 is installed on one end of the luffing guide rail protruding from the outside of the tank cylinder, and the movable pull rod 43 is connected to the adjustable rotating rod 44 installed on the winding frame 10 on the same side.

The working principle of the luffing guide device 4 is shown in Figure 3. When the movable pull rod 43 pulls the luffing guide rail 41 through the adjustable rotating rod 44 as the winding frame moves up, the chute 411 of the luffing guide rail 41 and the coil The direction of the bobbin clamped by the winding frame changes from parallel to inclined, so the sliding angle of the guide block 233 limited by it is changed, that is, the angle of the spinning head fixing frame 231 is changed. According to the principle of leverage, it plays a role in changing the spinning direction. The effect of wire head angle. In the field of loose winding machines, through the above-mentioned coordinated operation of the luffing guide device and the winding device, a loose pineapple-shaped bobbin with loose edges can be formed, and the yarn rolls at both ends are shifted to the center to achieve loose edges and favorable The purpose of unwinding is to fundamentally change the disadvantages of the tight side of rectangular (or parallel) bobbins, and greatly improve the quality of loose bobbins.

The fixed-length control device 5 includes an infrared light-controlled wire detector 50, a thread cutter 60 and a single-chip microcomputer 70 for controlling the above-mentioned devices, and the single-chip microcomputer is connected with the host control device 9 through the RS-485 bus.

The guide porcelain head 53, the yarn positioning groove of the guide porcelain head 53 is hook-shaped, so that the yarn can vertically pass through the induction area of the guide porcelain head and the wire-sensing head up and down. The circuit board layout of the sensor head is shown in Figure 10. The control structure of the STM8S207 single-chip microcomputer 70 is shown in FIG. 5 , and the single-chip microcomputer of STMicroelectronics (ST) is used in this embodiment. The thread cutter 60 is a thread cutter that utilizes a drive circuit of ULN2003 to drive an electromagnet, and the electromagnet drives the scissors to cut the thread, and the drive circuit is connected to the single chip microcomputer 70 . By adopting the above solution, not only can alarm and indication functions be realized, but also one-key reset can be achieved, and the cost is low; the structure of the wire detector and the thread cutter is simpler and the cost is lower.

As shown in Figures 1 and 6, the winding frame 10 includes a U-shaped plate frame 11 made of aluminum alloy, which is made of an in-line movable left plate frame 111 and an L-shaped fixed right plate frame 112 pivotally connected by a return spring 113. , and fixed on the left and right plate frames, the left and right chucks 12 that clamp the yarn bobbin core 13 can be fixed by the elastic force of the return spring of the pivot joint. The adjustable turning bar is installed on the rear part of the fixed right board frame and is on the outside. Compared with the existing iron material, the cost is greatly reduced due to the use of aluminum alloy material, and the weight is reduced to make it easier for the operator to change the canister. The above-mentioned clamping design can ensure that the weight is reduced while , to further increase the clamping force. The installation position of the adjustable rotating rod can ensure that the upward movement of the winding frame along with the thickening of the bobbin is more accurately and smoothly transmitted to the movable pull rod, and the cost is relatively low. The left and right chucks belong to the prior art in this field, and can be consistent or inconsistent. The surface of the chucks is a circular protrusion, and the size corresponds to the core of the yarn bobbin.

The bottom 212 of the tank body is semicircular, and the cover plate 211 of the tank body is a flat cover plate. Due to the use of aluminum alloy materials, material costs and energy consumption are greatly reduced. The tank body is generally filled with oil, and the bottom of this embodiment is semicircular, corresponding to the circular reciprocating device. Compared with the existing cuboid shape, it reduces the gap while not affecting the traverse operation. Moreover, the material used for the tank body and the oil used are saved, and the load of the motor driving the traverse reciprocating device is further reduced. The trough body 21 is obliquely installed on the frame plate through the trough body joint, the spinneret side of the trough tube faces upwards, and keeps the direction in which the winding frame clamps the bobbin core and the traverse direction of the traversing reciprocating device In the parallel position, the angle between the cover plate of the tank body and the horizontal plane is 10°-30°, the shaft of the tank body is installed on the frame, and one or both ends are exposed for gear assembly. Adopting this design, combined with the following tension adjustment device, can greatly facilitate the winding of the yarn, and realize high-speed winding. See below for details.

The winding device also includes a friction roller 30 . As shown in Figure 7, the friction roller 30 is cylindrical and is fitted on the friction roller shaft 31. The left and right sides are concave, and the inner rings 32 with external threads are respectively convexly installed on the two concave parts close to the friction roller shaft. , the inner ring is threaded with an outer ring 33 with an internal thread that can fix the friction roller on the friction roller shaft. The friction roller shaft 31 is installed on the frame and is located between the winding frame and the groove drum, with one or both ends Gear available for suiting is exposed. Compared with the existing fixing method of screwing against the roller, the method of this embodiment is more firm, and the installation and maintenance are convenient, and the operation is more stable, which is conducive to increasing the speed without damaging the roller. Will not affect the service life of the roller. The protruding inner ring can be divided into two pieces, three pieces or four pieces, the thickness of which increases gradually from the outside to the inside, and the ring holes of the outer ring correspond to the inner ring. Thus, on the one hand, the gap can be used to eliminate the internal force generated during threaded connection, and on the other hand, due to the existence of the slope, the inner and outer rings are combined more firmly, so that the friction roller is fixed more firmly.

Using the above scheme, not only can the yarn lateral reciprocating motion and winding motion be separated, but also can control the speed of the above two motions separately by adopting corresponding motor drive control, so as to realize the adjustment and determination of specific yarn lateral motion according to specific production requirements. The speed of reciprocating motion and the speed of winding motion effectively prevent overlapping and convex edges. In addition, the forming tank with special shape and structural design realizes precise winding, effectively prevents overlapping and convex edges, and ensures good winding formation and excellent unwinding performance.

As shown in FIG. 8 , the tension adjusting device 8 includes a guide piece 81 , an adjusting column 82 and an adjusting ring 83 . The center of the guide piece 81 is wide enough to place the adjusting ring 82. The two ends are narrow and are respectively equipped with a guiding ceramic head 811 and a limiting ceramic head 812. The yarn positioning groove of the guiding ceramic head 811 is hook-shaped, and the limiting ceramic head The yarn positioning groove of 812 is an isosceles triangle, and the two sides of the waist are raised and turned inside out. The adjusting column 82 is fixed on the middle part of the guide sheet, and is covered with rubber material. The adjusting post 82 can be fixed on the guide piece in various known ways. In this embodiment, a long screw covered with a rubber ring is threaded on the guide piece to save cost. In this embodiment, the ceramic head parts are all made of high-grade titanium porcelain and 99 porcelain to ensure the smoothness of the silk path. The adjustment ring is in the shape of a raised dome, and there is a ring hole in the middle that can be sleeved on the adjustment column. The inner area near the ring hole is a plane, and the outer side is a slope. The first adjustment ring is raised and sleeved on the adjustment column. Other adjustment rings can be sleeved downwards on the adjustment post according to tension needs, so that the yarn can be pressed against the adjustment post in the plane area of the adjustment ring. There can be multiple adjusting rings, which are used to adjust the tension of the yarn and realize fine-tuning tension control. In this embodiment, the protrusion of the first adjusting ring is firstly socketed on the adjusting column, and the yarn from the guiding ceramic head passes through the surface plane of the first adjusting ring and enters the limiting ceramic head. According to the size, the second adjustment ring and even the third adjustment ring can be raised and sleeved on the adjustment column facing downward.

The tension adjustment device 8 is obliquely installed in front of the tank cylinder 20 through the limit column 84, the limit ceramic head side faces upward and is close to the tank cylinder side, the angle between the guide plate and the horizontal plane is 10°-30°, and the guide ceramic head The center of the incoming line and the outgoing line center of the limit porcelain head are all on the middle cross section of the groove cylinder 20 traverse reciprocating stroke.

Since the incoming and outgoing wires are located on the middle cross-section of the horizontal reciprocating stroke of the groove drum 20, coupled with the unique inclination angle, it effectively prevents overlapping and convex edges during winding, ensuring good winding formation and unwinding performance Excellent, and achieve high-speed winding. The angle of inclination of the guide piece 81 and the angle of inclination of the tank body can be the same or different; the guide piece 81 can be planar, and preferably, the plane where the lower end of the guide piece 81 guides the ceramic head 811 can also be bent upward. Thereby it is beneficial to the winding and high-speed winding of the yarn. In this embodiment, the guide piece 81 is parallel to the cover plate 211 of the tank body, and the plane where the lower end of the guide piece 81 guides the ceramic head 811 is folded to be parallel to the horizontal plane. Adopting this scheme not only facilitates the tension adjustment, but also greatly facilitates the yarn feeding and winding, and realizes high-speed winding. As long as the yarn passes through the hook of the 811 yarn positioning groove of the guide ceramic head, and then is wound onto the yarn bobbin core held by the winding frame and fixed, the yarn will be automatically caught by the spinning head when the winding is started , and enter the yarn positioning groove of the limiting ceramic head 812 for high-speed winding.

The mode of use of the present invention is as follows:

Thread the yarn from the reel to be wound at the bottom into a single winding device, specifically: the yarn 200 first passes through the thread cutter and the thread detector, and then enters the guide ceramic head 811 yarn positioning groove hook , and then wound onto the bobbin bobbin core 13 clamped by the winding frame 10 and fixed, such as winding a few turns.

Then, start winding:

The lower winding frame 10 is close to the friction roller 30, and the friction roller motor 34 and the drum motor 24 are turned on. The friction roller shaft 31 drives the friction roller 30 to start rotating, and the friction roller 30 uses friction to push the bobbin to perform circular motion. At this time, when there are more and more yarns on the bobbin, the winding frame of the bobbin also moves upwards, and the adjustable rotating rod installed on the winding frame is connected with the movable pull rod, so the adjustable rotating rod drives the movable pull rod to move The pull rod pulls the luffing guide rail. When the angle of the luffing guide rail changes, the sliding angle of the guide block limited by it changes accordingly, that is, the angle of the spinning head fixing frame is changed. angle. Through the above-mentioned series of coordinated operations of the luffing guide device and the winding device, a loose pineapple-shaped bobbin with loose edges can be formed, making the bobbin yarn density more uniform and unwinding more convenient.

During the winding process, the yarn passes through the sensor head of the yarn detector, and different light control effects will be obtained. The yarn sensor can be used to detect whether the yarn is broken, whether the yarn is winding or stopping. The main control CPU sends the set fixed-length data and winding speed information to the fixed-length control device through the RS-485 bus. The fixed-length control device is controlled by a high-speed single-chip microcomputer, which detects the winding status of the yarn in real time, and obtains the winding length of the yarn through calculation. When the winding length reaches the set length, the thread trimming electromagnet is driven to cut the yarn, and the indicator light and alarm light are turned on. Rewinding is possible via the reset button. If there is yarn breakage during the winding process, the fixed length plate will light up the indicator light and alarm light. One fixed length board can control 4 spindles. The left side of the wire finder is the transmitting tube, and the right side is the receiving tube, using infrared rays, and of course the opposite can be done. Through infrared emission and reception, the yarn passes between the emitting head and the receiving head, and through the burrs of the yarn, the light is blocked differently. Through the circuit detection, it can be obtained whether there is yarn or not, and whether the yarn moves.

In addition, due to the existence of the inclination in the winding device, the spinning head 232 on the traverse reciprocating mechanism driven by the drum motor 24 will automatically catch the yarn and carry out lateral reciprocating motion. Due to the unique design of the body 21, the yarn will automatically enter the yarn positioning groove of the limiting ceramic head 812 for high-speed winding. At this time, it can be adjusted through the adjustment ring 83 according to the needs of the tension in the actual operation. When the yarn passes through the upper surface plane of the first adjusting ring and enters the limit ceramic head 812 to start winding, the second adjusting ring or even the third adjusting ring can be raised and fitted downwards on the adjusting column to press down yarn so that the yarn travels against the adjustment post 82 in the planar area of the adjustment ring 83 . Finally, change the reel: after the winding is completed, lift the winding frame 30, the drive motor is turned off, the friction roller shaft 31 and the traverse reciprocating mechanism 23 in the groove drum gradually stop moving, at this time, the operator supports the full yarn reel, Push away the left plate frame 111, take off the full yarn bobbin, and replace the empty yarn bobbin, and the return spring 113 makes the winding frame 10 return to the clamping state.

In the winding, the winding route of the yarn on the bobbin is a reciprocating helix, and the winding of the bobbin is formed by the superposition of two motions of rotating motion and reciprocating motion. Among them, the friction roller motor drives the bobbin to rotate and wind, and the grooved drum motor drives the spinning head in the grooved drum to reciprocate. Rotational motion produces peripheral speed V1, and reciprocating motion produces yarn guiding speed V2, then winding production speed: V=(V12+V22)1/2, tgα=V2/V1; α is called the winding angle of the yarn circle, also known as the yarn circle The helix angle is one of the main parameters in designing the winding mechanism. Through "production speed" and "intersection angle (2α)", the winding V1 and yarn guiding speed V2 can be obtained to calculate the control speed of the friction roller motor inverter and the groove drum motor inverter. The frequency converter is used to control the motor of the friction roller and the motor of the grooved drum, and the speed of the motor can be adjusted. The technical proposal can modify the "intersection angle (2α)" through software, so as to meet the production requirements of various yarns.

Anti-folding design in the winding process. When the bobbin is wound, each yarn coil wound on the surface of the bobbin should have a certain amount of displacement to the yarn coil in front of it. In this way, the loops are evenly distributed over the surface of the package. But if the displacement of the yarn coil is exactly equal to zero, that is, when the displacement angle of the yarn coil is equal to zero, then the yarn coil wound on the surface of the bobbin in the next yarn guiding cycle is still at the position of the yarn coil wound on the surface of the bobbin in the previous yarn guiding cycle , this phenomenon is called overlapping winding of yarn coils. The uneven overlapping strips on the package make the contact between the package and the drum poor, and the yarn in the raised part is damaged by excessive friction, resulting in yarn breakage and fluffing of the yarn body in the post-processing process. Overlapping slivers will cause uneven winding density of the bobbin and reduce the winding capacity of the bobbin. When unwinding the yarns of overlapping bobbins, because the yarns are embedded in each other or closely stacked, the unwinding resistance increases, and loops and random yarns will also occur. Packages that overlap too much will hinder the penetration of the dye solution, resulting in uneven dyeing. In this technical solution, since the yarn lateral reciprocating motion is separated from the winding motion, and the speeds of the above two motions can be controlled separately through the corresponding motor drive, the anti-stacking effect can be improved through corresponding settings.
