A winding type yarn-forming device for splicing ring-spun yarns

Abstract

This invention relates to a technique for creating a new yarn end on a ring-spun yarn bobbin when the yarn end breaks or when the yarn end cannot be successfully retained. Specifically, it is a device for creating a new yarn end on a ring-spun yarn bobbin, comprising a bobbin pulling device, a yarn guiding device, and a yarn taking device. The device creates a new yarn end by spiraling the yarn guide relative to the yarn bobbin and the yarn end of the yarn guide, thereby winding the yarn guide onto the yarn bobbin. Specifically, the bobbin pulling device pulls the yarn bobbin off the spinning machine and moves it to the winding position; the yarn taking device clamps the yarn end of the yarn guide and keeps it stationary with the yarn bobbin; and the yarn guiding device pulls the yarn guide in a spiral motion to wind the yarn guide onto the yarn bobbin, thereby creating a new yarn end. This invention can reliably create a new yarn end by winding the yarn guide onto the broken yarn bobbin or the empty yarn bobbin where the yarn end could not be successfully retained.

[0001] The present application relates to the technology of winding type starting for the bobbin when the ring spinning yarn breaks or when the head is unsuccessful, in particular to a winding type starting device for ring spinning yarn joint, which comprises a bobbin pulling device, a guide device and a yarn taking device, the winding type starting device for ring spinning yarn joint makes the joint yarn be wound on the bobbin to realize starting in a way that the joint yarn generates spiral motion relative to the bobbin and the joint yarn head, in particular, the bobbin pulling device pulls the bobbin from the spinning frame and moves the bobbin to the winding position, the yarn taking device clamps the joint yarn head and keeps the bobbin still, the guide device pulls the joint yarn to make spiral motion to wind the joint yarn on the bobbin to realize starting, the present application can reliably realize winding the joint yarn on the bobbin after the yarn breaks or the empty bobbin after the head is unsuccessful to complete starting. BACKGROUND

[0002] In the textile industry, ring spinning frame is one of the most important production equipment, after the ring spinning frame breaks, the operator generally needs to pull the bobbin from the spindle, find the yarn head on the bobbin, insert the bobbin into the spindle after the yarn head passes through the ring, and twist the yarn to the front roller output after the yarn passes through the guide hook, in this way, no matter how many joints a bobbin has, it is a continuous yarn. The joint process is relatively complex and is not suitable for automation.

[0003] When the ring spinning yarn is spun to the full drop and starts to spin a new drop, the spindle position that fails to retain the head needs to be started manually by the operator, when the operator starts, the starting yarn is hung into the ring, one end of the ring is wound on the bobbin (which may not be limited to one turn), and then gently pulled to wind the yarn on the bobbin by the rotation of the bobbin, or the end of the starting yarn is close to or pressed on the surface of the bobbin, and the starting yarn is wound on the bobbin by the rotation of the bobbin, once the starting yarn is effectively wound on the bobbin, the other end of the starting yarn must be quickly raised through the guide hook part to add twist to the starting yarn by the rotation of the ring, otherwise the starting yarn will be quickly wound on the bobbin and be pulled off. The starting operation of the ring spinning yarn is common knowledge in the industry and will not be repeated, but the starting operation has never been used for joint after the yarn breaks in the industry.

[0004] Although the automatic joint device for the ring spinning frame has been developed at present, and the automatic joint of the ring spinning can be completed, there are still obvious problems in the practical feasibility and the success rate of operation for some related patents of the automatic joint of the ring spinning at home and abroad. On the one hand, the success rate of the automatic joint is not high, the joint time is long, especially the success rate of finding the broken end on the tube yarn is not high after the spun yarn is broken, which leads to the low success rate of the automatic joint technology with the head finding link, on the other hand, the structure of the joint device is complex, the price is high, and it is not suitable for wide range of popularization and application.

[0005] In recent years, the fine loop connection technology and the automatic tube feeding, tube arranging, head forming and tube feeding technology matched with the automatic cone winder are gradually mature and can be widely applied. Assuming that a tube yarn contains multiple discontinuous spun yarns, the last spun yarn on the tube yarn is firstly wound on the cone yarn during the winding process, then the tube yarn is discharged by the cone winder and is transported to the automatic head forming position by the automatic conveying system of the cone winder to be reformed, and then reenters the doffer station to be rewound to wind the second spun yarn on the cone. This process is repeated until all the spun yarns on the tube yarn are wound.

[0006] In view of the above problems and background, the application discloses a winding type head forming device for ring spinning joint, which is used for winding the joint yarn on the yarn tube to realize the joint, is beneficial to reducing the complexity of the automatic joint, does not need the operation of finding the yarn head, is more stable and reliable in work, is beneficial to realizing the automatic joint after the ring spinning yarn is broken, and can also be used for head forming under the condition that the head finding after one doffer spinning is unsuccessful. SUMMARY

[0007] In view of the deficiencies of the prior art, the technical problem to be solved by the application is to provide a winding type head forming device for ring spinning joint, and the solution is:

[0008] A winding type head forming device for ring spinning joint, which comprises a tube pulling device, a yarn guiding device and a yarn taking device.

[0009] The tube pulling device comprises a yarn tube device and a yarn tube moving device. The yarn tube device is a component for clamping the yarn tube from the outside of the top end of the yarn tube or a component for supporting the yarn tube from the inner hole of the top of the yarn tube. The yarn tube device is installed on the yarn tube moving device, and the yarn tube moving device drives the yarn tube device to have at least spatial orthogonal three direction movement freedom.

[0010] The yarn guiding device comprises a rear yarn guiding port, a yarn holding device, a front yarn guiding port and a yarn guiding moving device.

[0011] The rear yarn guide is a hole part, and the joint yarn passes through the hole of the rear yarn guide, and the joint yarn is limited in a certain position;

[0012] The yarn holding device comprises a yarn holding part, a yarn holding driving part and a yarn holding guiding part, the yarn holding part is a pair of parts with relative close and separate movement, the yarn holding driving part drives the yarn holding part to close and separate to hold and release the joint yarn passing through, and the yarn holding guiding part guides the movement of the yarn holding part;

[0013] The front yarn guide is a ring part with an opening through which the joint yarn can pass;

[0014] The yarn holding device is located between the rear yarn guide and the front yarn guide, and the joint yarn passes through the rear yarn guide, the yarn holding device and the front yarn guide in sequence,

[0015] The rear yarn guide, the yarn holding device and the front yarn guide are installed on the yarn guide movement device, the yarn guide movement device drives the rear yarn guide, the yarn holding device and the front yarn guide to have at least three orthogonal direction movement degrees of freedom and one swing degree of freedom, the three orthogonal directions are the vertical direction, the horizontal direction parallel to the length direction of the spinning frame and the horizontal direction perpendicular to the length direction of the spinning frame, and the swing degree of freedom is preferably the swing around the horizontal shaft of the length direction of the spinning frame,

[0016] When the yarn holding device holds the joint yarn and the roller and the roller are pulled off, the length of the joint yarn remaining at the yarn holding device is uncertain, which is not conducive to improving the reliability of the joint, in order to control the length of the joint yarn remaining at the yarn holding device, a yarn cutting device is arranged between the front yarn guide and the yarn holding device of the yarn guide device, the yarn cutting device comprises a yarn cutting tool and a cutting driving device, the cutting driving device drives the cutting tool to cut the joint yarn, the rear yarn guide, the yarn cutting device, the yarn holding device and the front yarn guide are installed adjacently, the joint yarn passes through the rear yarn guide, the yarn holding device, the yarn cutting device and the front yarn guide in sequence, and the yarn holding device and the yarn cutting device both hold or cut the yarn by using two parts with relative movement.

[0017] The yarn taking device comprises a yarn taking clamping part and a yarn taking movement device,

[0018] The yarn taking clamping part is a part with a structure for positioning the joint yarn, the structure for positioning the joint yarn refers to a hook structure or a clamping structure capable of holding the yarn, which is used to keep the joint yarn in the structure for positioning the joint yarn when needed, the yarn taking head clamping structure capable of clamping the joint yarn preferably adopts the opening and closing movement of two parts to clamp the joint yarn or adopts the elastic structure to clamp the joint yarn;

[0019] The yarn taking movement device is a device with at least three orthogonal direction movement degrees of freedom, and the yarn taking clamping part is installed on the yarn taking movement device.

[0020] The yarn taking device comprises a yarn blowing air nozzle, which is installed adjacent to the yarn taking clamping part, and the outlet of the yarn blowing air nozzle blows gas towards the joint yarn guide clamped by the yarn taking clamping part.

[0021] Through the above mechanism and device, the working principle of the yarn winding type splicing device for ring spinning yarn joint is as follows:

[0022] After the joint yarn is unwound from the tube or cone, the end of the joint yarn passing through the rear yarn guide is clamped by the yarn holding device, the yarn taking movement device moves the yarn taking clamping part between the yarn holding device and the rear yarn guide to clamp and fix the joint yarn, the yarn taking clamping part pulls the joint yarn out of the rear yarn guide, and the joint yarn is hung into the open ring-shaped front yarn guide under the cooperation of the yarn guide device and the yarn taking device, and then the front yarn guide is driven by the yarn guide movement device to swing to the upright state to prepare for yarn winding.

[0023] When the ring spinning yarn spindle breaks or the splicing is unsuccessful and needs to be re-spun, the joint device reaches the broken yarn spindle position, the yarn tube movement device first moves the yarn taking tube device to the upper end of the broken yarn tube on the spinning frame, the yarn taking tube device clamps the top end of the yarn tube, the yarn tube movement device drives the yarn taking tube device to move upwards to pull the yarn tube out of the spindle, and then the yarn tube movement device moves the yarn tube to the yarn winding position, the yarn taking clamping part clamps the joint yarn close to the tube, and the yarn guide movement device drives the front yarn guide to make winding movement relative to the yarn tube to wind the joint yarn on the tube or yarn tube. During the winding process of the joint yarn, the tube pulling device and the yarn taking clamping part are relatively stationary, and after the joint yarn is wound on the tube or yarn tube for a length, the yarn taking clamping part releases the yarn end of the joint yarn. Generally, the joint yarn is wound more than one turn on the tube or yarn tube, and the joint yarn clamped by the yarn taking clamping part will be pressed. Even if the yarn taking clamping part releases the yarn end of the joint yarn, it does not affect the continuous splicing. The released yarn end will be pressed by the subsequent joint yarn wound on the tube, and the yarn winding type splicing of the ring spinning yarn joint is completed. When the front yarn guide winds the last turn of yarn on the winding tube, the front yarn guide guides the joint yarn through the clamping position of the yarn taking clamping part, the yarn taking clamping part clamps the joint yarn, and then the yarn taking device and the yarn guide device cooperate to hang the joint yarn in the wire loop. How the yarn taking device and the yarn guide device hang the joint yarn in the wire loop is not within the scope of the present application. Finally, the tube pulling device puts the spliced yarn tube on the spinning frame spindle, the yarn tube releasing device releases the yarn tube, and then the yarn guide device pulls the joint yarn to complete the winding steps of the guide hook winding the skin roller, etc. After the joint is completed, the yarn cutting device cuts the joint yarn and the yarn holding device holds the joint yarn end for the next joint work.

[0048] The yarn holding device includes a yarn holding component, a yarn holding drive component, and a yarn holding guide component. The yarn holding component includes a holding and cutting movable support 214, a yarn holding block 218, and a yarn holding pressure plate 219. The yarn holding drive component is a holding and cutting cylinder 213 mounted on a yarn guide support 212. The yarn holding guide component includes two guide rods, one end of which is fixedly mounted on the holding and cutting movable support 214, and the other end of which slides within the yarn guide support 212. The cylinder rod of the air-cutting cylinder 213 is connected to the holding and cutting moving bracket 214. The yarn holding pressure plate 219 is installed on the holding and cutting moving bracket 214. The yarn holding block 218 is an elastic body. The yarn holding block 218 and the yarn holding pressure plate 219 are aligned and installed on the yarn guide support 212. When the cylinder rod of the holding and cutting cylinder 213 extends, it pushes the holding and cutting moving bracket 214 to drive the yarn holding pressure plate 219 to move and hold the yarn end of the cut joint between them with the yarn holding block 218.

[0049] The yarn cutting device includes a yarn cutting blade 217 and a cutting drive device. The cutting blade 217 and the yarn holding pressure plate 219 are mounted adjacent to the holding and cutting moving support 214. When the cylinder rod of the holding and cutting cylinder 213 (which also serves as the cutting drive device) extends, it pushes the holding and cutting moving support 214 to move the yarn holding pressure plate 219 and the cutting blade 217. The cutting blade 217 and the yarn guide support 212 cut the yarn at the joint. At the same time, the yarn holding pressure plate 219 and the yarn holding block 218 hold the cut end of the yarn at the joint. Since the yarn holding device can be pulled off by the roller and the skin roller after holding the yarn at the joint, the yarn output device does not necessarily need to include a yarn cutting device. Having a yarn cutting device is more conducive to accurately controlling the length of the yarn left at the joint than not having a yarn cutting device.

[0050] Both yarn holding devices and yarn cutting devices utilize two relatively moving components to hold or cut yarn. For example, the yarn holding pressure plate 219 and the cutting blade 219 are mounted on one side of the yarn holding block 218, and the yarn holding block is mounted on the holding and cutting moving support 214. This can achieve the purpose of holding and cutting. Even swing holding and cross cutting can be used, all of which utilize relative motion to achieve the relevant holding and cutting functions.

[0051] The yarn picking device includes a yarn picking clamping component and a yarn picking moving device. The yarn picking clamping component includes a yarn clamping cylinder 341, a yarn clamping outer cavity 342, a yarn clamping cylinder rod 343, and a yarn clamping chuck 344. When the cylinder rod of the yarn clamping cylinder rod 343 extends, the yarn clamping outer cavity 342 separates from the yarn clamping chuck 344 to form a yarn clamping cavity. After the yarn is placed into the yarn clamping cavity, the cylinder rod of the yarn clamping cylinder rod 343 retracts, thereby achieving yarn clamping.

[0052] The yarn-picking clamping component is not limited to the scheme described in the embodiments. In addition to the clamping structure composed of two relatively opening and closing moving parts, any scheme that can clamp the end of the yarn guide at the connector can be used in the yarn-picking clamping component. For example, the commonly used V-shaped elastic clamping structure, the swing clamping structure similar to a hook needle, etc., can also be a cantilever rod with a "V" shaped groove structure or a hook-shaped structure at the end. When picking up the yarn, the yarn enters the "V" shaped groove at the end of the cantilever rod, and the yarn end is held by the friction of the inner wall of the "V" shaped groove, so as to realize the function of picking up the yarn.

[0053] The yarn taking moving device includes three orthogonal moving devices: a yarn taking Z-axis moving device, a yarn taking X-axis moving device, and a yarn taking Y-axis moving device. The yarn taking Z-axis moving device moves in a vertical direction, and the yarn taking X-axis moving device moves in a direction parallel to the length direction of the spinning machine. The yarn taking Z-axis moving device includes a yarn taking Z-axis guide component, a yarn taking Z-axis drive component, and a yarn taking Z-axis platform 316. The yarn taking Z-axis guide component includes a vertical yarn taking Z-axis guide rail 314 and a yarn taking Z-axis guide rail 316.

The yarn-picking Z-axis platform 316 is mounted on the yarn-picking Z-axis slider 315. The yarn-picking Z-axis lead screw nut 313 is mounted on the yarn-picking Z-axis platform 316. The yarn-picking Z-axis motor 311 drives the yarn-picking Z-axis platform 316 to reciprocate along the vertical direction through the yarn-picking Z-axis lead screw 312 and the yarn-picking Z-axis lead screw nut 313.

[0054] The yarn-taking X-axis moving device includes a yarn-taking X-axis guide component, a yarn-taking X-axis drive component, and a yarn-taking X-axis platform 326. The yarn-taking X-axis guide component includes a yarn-taking X-axis guide rail 324 horizontally mounted parallel to the length direction of the spinning machine on the yarn-taking Z-axis platform 316, and a yarn-taking X-axis slider 325 cooperating with the guide rail.

The yarn-taking X-axis guide rail 324 is mounted on the yarn-taking Z-axis platform 316, and the yarn-taking X-axis lead screw nut 323 is mounted on the yarn-taking X-axis platform 326. The yarn-taking X-axis motor 321 drives the yarn-taking X-axis platform 326 to move horizontally reciprocally along the length direction of the spinning machine through the yarn-taking Z-axis lead screw 322 and the yarn-taking X-axis lead screw nut 323.

[0055] The yarn-taking Y-axis moving device includes a yarn-taking Y-axis guide component, a yarn-taking Y-axis drive component, and a yarn-taking Y-axis platform 336. The yarn-taking Y-axis guide component includes a yarn-taking Y-axis guide rail 334 horizontally mounted on the yarn-taking X-axis platform 326 perpendicular to the length direction of the spinning machine, and a yarn-taking Y-axis slider 335 slidably configured along the yarn-taking Y-axis guide rail. The yarn-taking Y-axis drive component includes a yarn-taking Y-axis motor 331 mounted on the yarn-taking X-axis platform 326 and a yarn-taking Y-axis lead screw 332 connected to the shaft of the yarn-taking Y-axis motor. The yarn-taking Y-axis platform 336 is mounted on the yarn-taking Y-axis slider 335, and the yarn-taking Y-axis lead screw nut 333 is mounted on the yarn-taking Y-axis platform 336. The yarn-taking Y-axis motor 331 drives the yarn-taking Y-axis platform 336 to reciprocate horizontally along the length direction perpendicular to the spinning machine through the yarn-taking Y-axis lead screw 332 and the yarn-taking Y-axis lead screw nut 333.

[0056] The yarn taking device includes a yarn blowing nozzle 345, which is installed adjacent to the yarn taking clamping component. The outlet of the yarn blowing nozzle 345 faces the connector yarn held by the yarn taking clamping component. On the one hand, during the process of winding the connector yarn into the yarn tube, after the yarn taking clamping component releases the connector yarn, the yarn blowing nozzle 345 blows air to make the connector yarn swing downward, which makes it easier for the subsequently wound connector yarn to better press down on the end of the connector yarn, preventing the end of the connector yarn from swinging during the spinning process and affecting normal spinning. On the other hand, the blowing air from the yarn blowing nozzle 345 helps to clean the yarn taking clamping component and prevent fiber residue.

[0057] Based on the above mechanisms and devices, the working process of the winding type yarn-forming device for ring spinning yarn splicing is as follows:

[0058] After the yarn guide 215 is unwound from the bobbin or cone, it passes through the yarn guide tube 211. The end of the yarn guide 215 exiting the yarn guide tube 211 is held by the yarn holding device, such as... Figure 5 As shown, the yarn-taking moving device in the yarn-taking device moves the yarn-taking clamping component between the yarn guide port support 212 and the yarn guide tube 211 of the yarn holding device to clamp and fix the connector yarn guide 215, as shown. Figures 5-7 As shown, the yarn-taking clamping component pulls the yarn guide 215 out of the yarn guide tube 211. With the cooperation of the yarn guiding device and the yarn-taking device, the yarn guide 215 is hooked into the yarn guide opening 216. In this embodiment, the yarn guide opening 216 is a spiral curve shape, similar to the yarn guide hook of the ring spinning machine. Then, the yarn guide opening swing motor 251 drives the yarn guide opening 216 to a vertical state to prepare for yarn winding. When the ring spinning spindle breaks or the yarn head is not successfully retained and needs to be regenerated, after the splicing equipment reaches the broken spindle position, the tube pulling moving device first moves the tube pulling three-jaw cylinder 135 to the upper end position of the broken yarn tube on the spinning machine. The moving jaws of the tube pulling three-jaw cylinder 135 close to hold the upper end of the yarn tube 41, and then the tube pulling Z-axis moving device pulls the yarn tube 41 vertically out of the spindle. Figure 1 The three-degree-of-freedom tube-pulling device shown moves the yarn tube 41 to the winding position, as follows: Figures 8-10 As shown, the yarn guide 216, driven by the yarn guide translation device, performs a cross-spiral motion relative to the yarn tube 41 to wind the connector yarn guide 215 onto the yarn tube or yarn tube. After the connector yarn guide 215 has been wound onto the yarn tube or yarn tube for a certain length, the yarn clamping component opens to release the yarn end of the connector yarn guide 215. The released yarn end will stay close to the yarn tube and will be pressed down by the connector yarn guide 215 subsequently wound onto the yarn tube, such as... Figure 10As shown, when the yarn guide 216 makes its last circular motion around the yarn tube 41, the yarn tail of the connector yarn 215 on the bobbin passes through the clamping position of the yarn take-up clamping component. The yarn take-up clamping component clamps and fixes the yarn tail of the connector yarn 215. Then, the yarn take-up device and the yarn guide device work together to hang the connector yarn 215 into the wire traveler. How the yarn take-up device and the yarn guide device hang the connector yarn into the wire traveler is not within the scope of this application. Finally, the tube pulling device removes the yarn head. The completed yarn tube 41 is sent back to the position of the spindle on the spinning machine and inserted into the spindle bar. The three-jaw cylinder 135 is opened to release the yarn tube 41. The above process completes the winding yarn start-up of the ring spinning splice. Then, the yarn guide device pulls the splice yarn 215 to complete the splicing steps such as winding the guide hook and winding the roller. After the splicing is completed, the yarn cutting device cuts the splice yarn 215 and the yarn holding device holds the yarn end of the splice yarn 215 to prepare for the next splicing operation.

[0059] When winding the yarn guide onto the yarn tube, if you want to wind the yarn guide to a higher position on the yarn tube, the length of the yarn guide support 212 needs to be as long as possible. Figures 1-3 As shown, if you want to wrap the splice yarn around the joint... Figure 1 For positions where the winding position is higher, the length of the yarn guide support 212 needs to be greater than that of the yarn guide support 212. Figure 1 The guide post support 212 is long, for example, it becomes Figure 3 The length of the guide support 212 shown allows the yarn to be wound around the bobbin at any height.

[0060] Although this embodiment uses a three-jaw cylinder 135 as the yarn tube picking device, other claw-type structures or airbag-type gripping structures can also be used to grab the yarn tube from the outside, or a claw-type structure or airbag structure can be used to pry the yarn tube out from the inner hole at the top of the yarn tube.

[0061] The driving devices in the embodiments can all be replaced with common components and mechanisms with the same function. For example, cylinder-driven movement can be replaced with linear motors, rotary motors with lead screws, motors with cam push rods, electromagnets, etc., and guidance can be achieved using optical axes, sliders, or linear guides, etc. These are all common knowledge in the art and will not be elaborated further. The present invention is not limited to the embodiments discussed above. Those skilled in the art can deduce other variant forms based on the present invention, and these variant forms are also part of the subject matter of the present invention.
