Description

Technical Field

[0001] The invention relates to the technical field of yarn winding, in particular to a yarn winding device for a warping machine. Background Art

[0002] Yarn is a kind of textile, which is processed from various textile fibers and has a certain fineness. It is mainly used for weaving, rope making, thread making, knitting and embroidery. When producing yarn, warping machines are often used to weave the warp yarns. When warping machines weave the warp yarns, winding mechanisms are often used to wind the yarns together.

[0003] The yarn of some winding mechanisms often breaks during the winding process. Most of the existing yarn breaking mechanisms are set at the position where multiple yarns are gathered. As a result, when a single yarn breaks, the yarn breakage is often not discovered immediately, resulting in incomplete winding of the yarn. The broken yarn is not fixed in time, which will cause the yarn on the winding roller and the pay-off roller to become loose. As a result, after the yarn breakage is discovered later, the loose yarn on the winding roller and the pay-off roller must be straightened when the yarn is adjusted, which takes more sorting time. In addition, the tension of many winding mechanisms is insufficient, and the yarn breakage caused by insufficient tension is more likely to occur. Summary of the invention

The other end of the connecting rod 76 away from the fixing rod 75 is rotatably assembled and connected to the wire pressing unit 8.

[0057] Moreover, the tension adjustable unit 5 includes a first fixed frame 54, which is installed on the upper surface of the first mounting frame 3. A plurality of tension plates 53 are symmetrically rotatably arranged on the upper and lower layers of the first fixed frame 54, and a pushing frame 52 is rotatably connected to one side of the tension plate 53. A servo electric cylinder 51 is connected to one side of the pushing frame 52. The servo electric cylinder 51 is arranged on the upper surface of the first mounting frame 3 on one side of the first fixed frame 54. The servo electric cylinder 51 can provide more accurate positioning and fast real-time feedback.

[0058] In addition, a rotating seat 531 is provided in the middle of the tension plate 53, and the tension plate 53 is arranged to rotate on the rotating seat 531. The rotating seat 531 is installed on the upper surface of the plate body of the first fixed frame 54. Tension wheels 533 are symmetrically rotatably provided on both sides of the rotating seat 531 on the upper surface of the tension plate 53. A rotating head 532 is provided at the bottom end surface of one side of the tension plate 53. A pushing frame 52 is rotatably connected to the rotating head 532. The tension wheel 533 can increase the tension of the yarn during winding.

[0059] Moreover, the pushing frame 52 includes a connecting rod 521, and push plates 522 are symmetrically and horizontally fixed at the upper and lower ends of the connecting rod 521. The push plate 522 is in a mountain shape, and a through hole 523 is opened on the protruding plate of the push plate 522. The push plates 522 are rotatably connected to each tension plate 53 on the same plane. The output end of the servo electric cylinder 51 is equipped with a push rod 511. The other end of the push rod 511 away from the output end of the servo electric cylinder 51 is rotatably connected to the middle part of the connecting rod 521.

[0060] In addition, the line break alarm unit 6 includes a second fixed frame 61, and a plurality of sliding frames 62 are arranged on the upper surfaces of the upper and lower layers of the second fixed frame 61. A wire pressing mechanism 63 is slidably arranged on the sliding frame 62. The sliding frame 62 includes a fixed seat 621, and the fixed seats 621 are evenly arranged in the horizontal direction on the upper surface of the plate body of the second fixed frame 61, and a first slide bar 622 is arranged between every two fixed seats 621, and a second slide bar 623 is arranged above the first slide bar 622. The wire pressing mechanism 63 is slidably arranged on the first slide bar 622 and the second slide bar 623, and the sliding frame 62 realizes linear movement through the first slide bar 622 and the second slide bar 623.

[0061] In addition, the wire pressing mechanism 63 includes a sliding base 631, which is slidably arranged on the first slide bar 622 and the second slide bar 623. A connecting plate 632 is vertically fixed on the upper surface of the sliding base 631. A ceramic pressing ring 633 is fixedly connected to the upper end of the connecting plate 632. The ceramic pressing ring 633 has better wear resistance and smoothness, so that it will not wear the yarn.

[0062] Moreover, a spring 624 is connected between the sliding base 631 and the fixed base 621 close to its right side. The spring 624 is sleeved on the outside of the rod body of the second sliding rod 623. One end of the spring 624 is connected to a side wall of the fixed base 621 body, and the other end of the spring 624 away from the fixed base 621 is connected to a side wall of the sliding base 631 body. A distance sensor 64 is installed on the upper surface of each fixed base 621 arranged on the left side of the ceramic pressure ring 633, and the emitting end of the distance sensor 64 faces the side of the ceramic pressure ring 633. The contraction force of the spring 624 is small. When the yarn presses the ceramic pressure ring 633, the sliding base 631 at its bottom can move.

[0063] In addition, the wire crimping unit 8 includes a slide rail 81, which is installed on the front side surface of the frame body on both sides of the front end of the wire pay-off frame 9, and a first wire crimping frame 82 is slidably arranged on the slide rails 81 on both sides, and a first rubber block 823 is arranged on the upper surface of the plate body of the first wire crimping frame 82, and a connecting seat 821 is symmetrically arranged in the middle part of the bottom end surface of the plate body of the first wire crimping frame 82, and the connecting seat 821 is rotatably connected to the other side end of the connecting rod 76 away from the fixed rod 75, and sliding feet 822 are symmetrically arranged on both sides of the plate body of the first wire crimping frame 82, and the sliding feet 822 are slidably arranged on the slide rails 81 on both sides, and the first wire crimping frame 82 can realize up and down linear movement through the slide rails 81.

[0064] In addition, a second wire crimping frame 91 is arranged at the front end surface of the front end frame of the wire pay-off frame 9, and is located directly above the first wire crimping frame 82, and a plurality of wire guide rods 93 are arranged on one side of the second wire crimping frame 91, and a plurality of wire pay-off rollers 92 are arranged on the rear side frame of the wire pay-off frame 9. The second wire crimping frame 91 includes a fixed plate 911, and the fixed plate 911 is fixed on the wire pay-off frame 9. A second rubber block 912 is arranged on the bottom end surface of the fixed plate 911. The second rubber block 912 can be fitted with the first rubber block 823. The second rubber block 912 can be fitted with the first rubber block 823, so that the yarn passing through the middle can be fixed in time to prevent it from retreating to the wire pay-off roller 92, causing the yarn on the wire pay-off roller 92 to become loose.

[0065] In this embodiment, when warping and winding the yarn for wool and silk textile, the whole machine winding mechanism can be used to complete it. First, the pay-off roller 92 wound with the yarn is installed on the pay-off frame 9, and then the yarn on each pay-off roller 92 is pulled out, the yarn end is pulled out, and then the yarn is first passed through the guide ring of the guide rod 93, and then passed through the corresponding guide hole on the first guide plate 4. After the yarn passes through the first guide plate 4, the yarn can be inserted into the tension adjustable unit 5.

[0066] First, find the tension plate 53 corresponding to the yarn, pass the yarn through the left side of the tension wheel 533 close to the first wire guide plate 4, and then pass it through between the tension wheels 533 on both sides to the right side of the other tension wheel 533. At this time, the yarn has completed the journey through the adjustable tension unit 5, and then the yarn can be passed through the broken wire alarm unit 6 on one side, and the wire pressing mechanism 63 on each corresponding sliding frame 62 is found. When the adjustable tension unit 5 is not used to adjust the tension, ensure that the yarn is placed on the inner ring of the ceramic pressure ring 633, and then the yarn can be passed through the wire wheel frame 13, and ensure that each yarn is located on the left side of the corresponding wire wheel.

[0067] After the yarn passes through the wire wheel frame 13 and the corresponding wire guide hole on the second wire guide plate 10, the yarn can be inserted into the wire guide unit 2. First, the yarn is passed through the wire collector 24, and the two adjacent strands of yarn are passed into the corresponding wire collecting groove 2421 at the bottom, and then passed through the wire guide plate and other components on the wire guide seat 22. Then, it is wound on the winding roller 14 of the winding mechanism box 1. After all the yarns are wound, the winding roller 14 of the winding mechanism box 1 is started to rotate so that it can first wind up the yarn for a distance, thereby ensuring that the yarn is slightly tightened. Then, the tension adjustable unit 5 can be driven to perform preliminary tension adjustment.

[0068] First, the servo electric cylinder 51 is driven to retract the push rod 511 at its output end by connecting the control terminal to the PLC. After the push rod 511 retracts backward, the push rod 511 pulls the connecting rod 521, so that the connecting rod 521 drives the push plates 522 at the lower ends to move backward. Because the through hole 523 of the push plate 522 is set on the rotating head 532 of the tension plate 53, when the push plate 522 moves backward, it can drive the tension plate 53 to move.

[0069] Because the tension plate 53 can only rotate around the rotating seat 531, when the push plate 522 moves backward, the tension plate 53 can only rotate counterclockwise due to the limitation of the rotating seat 531. When the tension plate 53 rotates counterclockwise around the rotating seat 531, the two tension wheels 533 on the tension plate 53 will slowly press the yarn, so that the originally taut yarn is squeezed by the tension wheel 533, and the tension becomes greater. In addition, the tension wheel 533 close to the side of the wire break alarm unit 6 will slowly shift the yarn on its right side because of the counterclockwise rotation, so that the yarn originally from the tension adjustable unit 5 to the wire wheel frame 13 can be straightened while the original state of the yarn becomes more offset, so that the yarn will trigger the wire break alarm unit 6 in this process.

[0070] The servo electric cylinder 51 is controlled by PLC to realize one-button automatic pushing and retraction, and the servo electric cylinder 51 can provide more accurate positioning and fast real-time feedback, so as to control the retraction and pushing distance of the push rod 511, thereby realizing the adjustment of the yarn tension.

[0071] After the yarn is stretched straight, the yarn originally placed on the inner ring of the ceramic pressure ring 633 will be stretched straight and located at the center of the ceramic pressure ring 633. Then, after the tension is adjusted by the tension adjustable unit 5, the rotation of the tension wheel 533 causes the yarn between the wire wheel frame 13 and the tension adjustable unit 5 to shift as the position of the tension wheel 533 changes. In this process, the stretched yarn will slowly approach the ceramic pressure ring 633 on the right, and the yarn will contact the ceramic pressure ring 633. While the yarn presses the ceramic pressure ring 633, the spring 624 will contract and the yarn will continue to shift. At this time, while the yarn is shifting, the ceramic pressure ring 633 will carry the sliding base 631 at the bottom to move horizontally to the right on the first slide bar 622 and the second slide bar 623. Under the joint restriction of the first slide bar 622 and the second slide bar 623, the sliding base 631 can only move horizontally in a straight line.

[0072] After the sliding base 631 moves horizontally, the distance between the connecting plate 632 and the distance sensor 64 will become larger, so that the distance measured by the distance sensor 64 and the connecting plate 632 will become larger. When the yarn does not hold the ceramic pressure ring 633 to move, the ceramic pressure ring 633 is connected to the sliding base 631 by the action of the spring 624 on one side, so that when there is no yarn pressing on the ceramic pressure ring 633, the ceramic pressure ring 633 will always be at a fixed point on the sliding frame 62. When the ceramic pressure ring 633 is at the fixed point, the distance sensor 64 measures the distance between the connecting plate 632 as a fixed value, and the fixed value of each ceramic pressure ring 633 at the fixed point is the same. This fixed value is the distance value fed back by the ceramic pressure ring 633 when there is no yarn pressing. The distance sensor 64 is an infrared ranging sensor, which is a prior art and is well known to people in the field of ranging sensors, so its structure and principle need no further elaboration.

[0073] After the winding roller 14 of the winding mechanism box 1 is initially started and the yarn is adjusted to a proper position to ensure that the yarn is in a taut state, the winding roller 14 can be opened for rapid winding. The yarn is released by the pay-off roller 92 and then guided to the first wire guide plate 4 by the wire guide rod 93. Then, the yarn passes through the first wire guide plate 4 to the tension adjustable unit 5 and then passes through the wire break alarm unit 6. Under the rapid winding of the winding roller 14, the yarn will be in a taut state, thereby ensuring that the yarn can press the ceramic pressure ring 633 while moving it. After the yarn passes through the wire break alarm unit 6, it is guided to the second wire guide plate 10 by the wire wheel frame 13. Then, the two adjacent strands of yarn will be gathered to the wire collector 24 for preliminary wire collection, and then pass through the wire guide plate on the lower wire guide seat 22 to guide the yarn to the winding roller 14 for winding. In the process, the wire guide seat 22 will move laterally on the driving frame 21 to ensure that the yarn will be evenly wound on the winding roller 14.

[0074] Moreover, the second wire collecting head 242 is replaceable, because it is connected to the first wire collecting head 241 through a fixing component, so it can be replaced regularly to ensure that the second wire collecting head 242 will not wear the yarn, and the second wire collecting head 242 is made of a material including but not limited to ceramic, which is very wear-resistant and smooth, and the wire blocking rod 2422 provided can play a certain limiting role to prevent the yarn from escaping from the wire collecting groove 2421, and because the first wire collecting head 241 is fixed on the wire guide seat 22, when the wire guide seat 22 moves laterally, the wire collector 24 will also move synchronously.

[0075] When the distance sensor 64 is winding the winding roller 14 of the winding mechanism box 1, the distance sensor 64 will be turned on. At this time, because the data collected by the distance sensor 64 is different from the fixed value collected by the ceramic pressure ring 633 at the fixed position, the distance sensor 64 will not alarm. Once one of the yarns breaks during the winding operation, the yarn will change from the original tight state to the loose state when the yarn breaks, so that the ceramic pressure ring 633 pressed by it will no longer be bound by the yarn, so that the spring 624 can release the elastic potential energy, pushing the sliding base 631 to the first slide bar 62 2 and the second slide bar 623, and push it to the original fixed position. At this time, the distance measured by the distance sensor 64 slowly approaches the fixed value. Once the measured distance reaches the fixed value, the distance sensor 64 will alarm, and the disconnection situation will be fed back to the control terminal through the disconnection alarm system. After the control terminal obtains the disconnection situation, it will be connected to the winding mechanism control system. The winding mechanism control system controls the winding mechanism box 1 to stop, so that the winding roller 14 stops winding. In order to prevent the yarn from making the yarn on the winding roller 14 loose, after the disconnection alarm system sounds an alarm, the disconnection protection unit 7 will operate synchronously.

[0076] After the control terminal receives the line break protection instruction, it will also control the operation of the motor 12 through the motor control system. The output end of the motor 12 will rotate clockwise, thereby driving the assembly disk 71 installed on its output end to rotate clockwise synchronously. After the assembly disk 71 rotates, the first fixed rod 72 and the second fixed rod 73 on both sides will rotate synchronously.

[0077] After the second fixed rod 73 rotates clockwise, the wire pressing rod 74 fixedly connected to it will rotate from its original higher position to the bottom. The wire pressing rod 74 was originally located above the winding roller 14. After rotating clockwise, the wire pressing rod 74 will rotate and press on the outer wall of the roller body of the winding roller 14, thereby contacting the woolen textile line wound on the winding roller 14, thereby pressing it tightly to prevent the broken line from loosening on the winding roller 14 and having to be rewound.

[0078] After the first fixing rod 72 on the other side rotates clockwise, the first fixing rod 72 will move upward from the original lower position to the higher position. In this process, the connecting rod 76 rotated on the fixing rod 75 of the first fixing rod 72 will push the first wire pressing frame 82. Because the two ends of the connecting rod 76 are respectively rotatably arranged on the fixing rod 75 and the connecting seat 821, the first wire pressing frame 82 can be pushed when the connecting rod 76 moves upward, and the sliding feet 822 on both sides of the first wire pressing frame 82 slide up and down linearly on the slide rail 81, so that when the connecting rod 76 pushes the first wire pressing frame 82, the first wire pressing frame 82 can only move linearly upward, so that the first rubber block 823 slowly approaches the second rubber block 912 above until it is fitted together. After the first rubber block 823 and the second rubber block 912 are fitted together, the yarn passing between the two is effectively clamped, thereby fixing the yarn and preventing it from retreating to the wire-releasing roller 92.

[0079] When resetting the wire break protection unit 7, it is only necessary to reset the motor 12 counterclockwise through the motor control system of the control terminal. At this time, the first wire pressing frame 82 will be pulled down by the connecting rod 76, and the wire pressing rod 74 on the other side will rise upward and leave the outer wall of the winding roller 14, and the movable opening 101 is used for the movement of the second fixed rod 73, and the limit block 102 can effectively block the second fixed rod 73, thereby limiting the rotation angle of the second fixed rod 73.

[0080] In the present invention, by setting up the adjustable tension unit 5, only one servo electric cylinder 51 is needed to rotate all the tension plates 53, so as to cooperate with the contact between the tension wheel 533 and the yarn to realize the tension adjustment of the yarn, ensure that the yarn can be further tightened, and prevent the yarn from loosening. Moreover, while the tension wheel 533 is adjusting the tension, the tension wheel 533 can also pull the yarn to press the ceramic pressure ring 633, and cooperate with the distance sensor 64 to realize that when the yarn breaks, the yarn breakage situation can be quickly detected, so that the equipment can be shut down to prevent the broken yarn from being wound around the machine. Moreover, this method can clearly understand which strand of yarn is broken, so that the yarn breakage situation can be discovered more quickly.

[0081] In addition, the wire breakage protection unit 7 can realize the synchronous protection of the yarn on the winding roller 14 and the pay-off roller 92 only by being driven by the motor 12. Under the pressure of the wire pressing rod 74 and the pressing of the first wire pressing frame 82 and the second wire pressing frame 91, the yarn is fixed to prevent the yarn from retreating to the pay-off roller 92 and the winding roller 14, and to prevent the yarn from becoming loose due to the retreating yarn, which does not require manual rewinding, thereby saving the time required for processing after yarn breakage.

[0082] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
