Description

Ring spinning yarn piecing device

Technical Field

Background

In the textile industry, a ring spinning frame is one of the most important production devices, after spinning of the spinning frame is broken, a blocking machine is generally required to pull the cop from the spindle, find the yarn end of the spun yarn on the cop, insert the cop onto the spindle after the yarn end passes through the bead ring, and splice the spun yarn to the whisker strip output by the front roller after passing through the yarn guide hook, so that no matter how many joints are arranged between one pipe of spun yarn, the joint process is complex, and in particular, the splicing process is difficult to realize.

Since the seventies of the twentieth century, the ring spinning automatic splicing technology has begun to appear, but the technology at that time is not perfect enough and is difficult to popularize and utilize in factory production. In the seventh eighties of the last century, the Hirspan type automatic joint device of Swiss Hirspan, the FIL-A-MAT type automatic joint device of Qingze, germany, and the Filasol automatic joint device of Kame, italy, have been developed. The blue-and-white FIL-A-MAT automatic joint device is developed by a base Yu Qingze type spinning frame in a matching way, the joint device is provided with a U-shaped track, the track surrounds the outer ring of the spinning frame, the joint device automatically advances on the track, when the broken ends of the spindles are found, the joint device is stopped before the corresponding spindles, the joint device is fixed on a ring rail, a bracket for joint operation is extended, the broken ends of the bobbins are firstly found, the bead rings are fixed at the determined positions by a set of positioning systems, the yarns are led to pass through all positions through a swinging rod, and finally the yarns are led into an output roller, so that the joint is completed. After the joint is finished, the photoelectric detection device judges whether the joint is successful or not. Filasol the automatic joint device can automatically check the joint and stop the related spindle, find out the broken joint from the bobbin, pass through the bead ring and the yarn guide hook, and finish the joint in front of the front roller jaw. The automatic spindle is braked firstly by the Sepal type connector, then the yarn tube is pulled out, the yarn end is held after the yarn end is found, and the cop is re-inserted, the steel wire ring is penetrated, the balloon ring and the yarn guide hook. In 2019, swiss RIETER introduced a ROBOspin automatic piecing robot matched with a G38 ring spinning frame, and the mechanical arm was used to take out the broken ends from the bobbins, then sequentially pass through the bead rings and the yarn guide hooks, and finally introduce the yarns into the jaw of the front roller to finish piecing. The spain pint company and langwei company of india each developed a break joint device.

Although an automatic joint device for a ring spinning frame has been developed at present, an automatic joint of a ring spinning frame can be completed, there are some related patents of the automatic joint of the ring spinning at home and abroad, but the practical feasibility, the success rate of operation and the like have obvious problems, on one hand, the automatic joint success rate is not high enough, the joint time is long, and particularly the success rate of finding out broken ends on cop after the broken ends of the spun yarn is not high enough, so that the joint success rate of an automatic joint technology with a finding link is low, on the other hand, the joint device has a complex structure and high price and is not suitable for being popularized and applied in a large scale. In recent years, the technology of fine winding and the technology of automatic tube feeding, tube management, head generation and tube feeding matched with an automatic winder are mature gradually and popularized and applied on a large scale, and supposing that a cop contains a plurality of discontinuous spun yarns, when the cop is wound in the winding process, a section of spun yarn finally spun on the cop is wound on the cheese first, then the cop is discharged by the winder, is conveyed to an automatic head generation position by an automatic conveying system of the winder, then enters a doffing station again for winding again, and the second section of spun yarn is wound on a bobbin, and the process is repeated until all the spun yarns on the cop are wound. That is, the automatic empty bobbin identification and sorting, automatic bobbin yarn conveying, automatic bobbin yarn end-spinning and automatic bobbin yarn feeding system matched with the automatic bobbin winder at present has the capability of automatically processing spun yarn bobbin yarns spun by sections.

In view of the above problems and the background, the invention discloses a ring spinning yarn splicing device, which utilizes a section of elastic yarn splicing to firstly hang the middle position of an elastic yarn splicing into a bead ring, envelope one end of the elastic yarn splicing onto a cop according to the twisting direction of spinning, and rapidly pass the other end of the elastic yarn splicing upwards through a yarn guiding hook and then wind between a front roller and a leather roller to realize splicing and continue spinning when the ring spinning yarns are broken. Compared with the existing ring spinning yarn splicing technology, the ring spinning yarn splicing device reduces the complexity of splicing operation, does not need operations such as tube drawing, yarn head finding and the like, works more stably and reliably, is beneficial to realizing automatic splicing after the ring spinning yarn breaks, and can be used for spinning after doffing is finished and leaving the yarn head unsuccessful.

After the bead ring 43 is hung, the yarn winding device moves forward to a position slightly higher than the top of the yarn tube 44 in the Z-axis direction (as shown in fig. 19), the cylinder rod of the yarn lifting guide hook cylinder 1375 in the yarn lifting guide hook device stretches out, the lifting component is pushed to move towards the direction close to the spinning frame to insert the rotating cross rod 1371 below the yarn guide hook 45, and the yarn winding device is driven by the yarn winding moving device to move forward to the Z-axis direction and the Y-axis direction simultaneously to lift the yarn guide hook until the yarn winding device is used for conveying the yarn coil wound by the elastic joint yarn 1215 on the yarn winding holder 134 to the position right above the yarn tube 44. The yarn Z-axis moving device drives the yarn winding holder 134 to a height position (as shown in fig. 20) adjacent to the upper surface of the ring 42, and the presser member 291 pushes up the yarn stopper 48 forward to the Z-axis to stop the bobbin 44. The yarn pressing part 111 moves to a yarn pressing station under the drive of the yarn pressing Z-axis moving device, the yarn pressing part 111 is rapidly pressed on the surface of the three cantilever rods (shown in fig. 20-21) of the yarn tube 44 and the yarn winding holder 134 by the yarn pressing Y-axis moving device, the yarn rings are pressed and fixed, the yarn ring clamping cylinder 1351 in the yarn picking ring part and the yarn head clamping cylinder 1361 in the yarn taking head clamping structure are simultaneously opened, the yarn heads of the section of elastic joint yarn 1215 and the tail ends of the yarn rings are released, at the moment, the cylinder rod of the yarn winding Z-axis lifting cylinder 1317 stretches out to drive the yarn winding holder 134 to rapidly move forward in the Z-axis direction (vertically upwards direction), the yarn rings wound by the elastic joint yarn 1215 are pressed by the yarn pressing part 111 and do not move upwards along with the yarn winding holder 134, the yarn rings of the elastic joint yarn 1215 are enveloped on the surface of the yarn tube 44, the yarn head part of the elastic joint yarn 1215 and the broken end envelopes of the original yarn are not thrown out due to the centrifugal force when the yarn is wound into the yarn ring, the yarn ring is not influenced when the yarn spinning is ensured to be spun inside the yarn ring, and the yarn ring cannot be lifted on the yarn ring is normally, and the yarn ring cannot be lifted on the yarn ring is in the yarn ring normally, and the yarn ring is not normally wound on the yarn ring is in the yarn winding state.

With respect to the claw-type yarn winding holder 134, since there is a gap between two rod-like members connected to one side closer to the spinning frame sufficient to pass the bobbin, there is a gap between them sufficient to pass the bobbin, and the yarn lifting guide hook device is provided with a rotating cross bar 1371, after the yarn joining coil on the yarn winding holder is separated from the yarn winding holder, the yarn pressing member 111 and the yarn winding holder 134 withdraw from the spinning area in a direction away from the spinning frame so as not to affect the subsequent yarn joining operation. If the rotary cross bar 1371 is not arranged on the yarn lifting and guiding hook device, the yarn winding retainer needs to be lifted to a height higher than the yarn tube before the yarn winding retainer withdraws in the direction away from the spinning machine, otherwise, the yarn lifting and guiding hook component can interfere with the yarn tube in the process of withdrawing the yarn winding retainer in the direction away from the spinning machine, and similarly, if the yarn winding retainer is of a cylindrical structure, the yarn winding retainer needs to be lifted to a height not interfering with the yarn tube before the yarn winding retainer withdraws in the direction away from the spinning machine, and then the yarn winding retainer can be horizontally withdrawn in the direction away from the spinning machine.

To this end, the elastic yarn 1215 is suspended in the bead ring 43 and one end is stably wound around the bobbin 44.

The yarn guide 1216 of the yarn discharging device pulls the yarn splicing to move to the position near the yarn guide hook 45, and the elastic yarn splicing 1215 is wound into the yarn guide hook 45 (as shown in fig. 22) under the cooperative movement of the yarn guide Y-axis moving device, the yarn guide Z-axis moving device, and the yarn guide X-axis moving device. Since the ring plate detecting device can detect the height position of the ring plate, the yarn guide hook fluctuates only in a small height difference range relative to the ring plate, and therefore, the connector yarn can be wound into the yarn guide hook according to the detected height position of the ring plate.

The elastic yarn 1215 is then pulled to the front roller 46 by the yarn feeding device, and the presser member 291 releases the stopper 48 to re-rotate the bobbin 44, thereby feeding the elastic yarn 1215 between the front roller 46 and the leather roller 47 while the leather roller 47 rotates (as shown in fig. 23 to 24). The elastic yarn-joining 1215 is cut and the yarn-cutting device is used to re-grip the yarn-joining end (as shown in fig. 25), the yarn on the yarn-guiding port side of the yarn-gripping device is pulled away by the roller and the leather roller, the cut yarn-joining end is gripped by the yarn-gripping device, the yarn-gripping device is used to grip and compress the elastic yarn-joining end 1215, and the elastic yarn-joining end 1215 gripped by the yarn-gripping device is pulled by the front roller 46 and the leather roller 47, so that the yarn-cutting device is not required. The way of jointing the winding roller is well known in the spinning industry, and the spun yarn can cause a rough knot in a part of yarn guiding sections, and the rough knot of the sections can be automatically removed in an automatic winding stage, so that the quality of the wound spun yarn is not affected. When the ring spinning frame is a compact spinning frame and the elastic yarn 1215 is hung by a "winding roller", the elastic yarn 1215 may be wound before the front roller 46 and the front roller 47, or may be wound around a roller matching the grid ring.

The above process completes the entire piecing process of this embodiment and leaves the ends of the grippable elastic piecing yarn 1215 for the next piecing.

As shown in fig. 2, a track parallel to the length direction of the ring spinning frame is additionally arranged on the ground outside the ring spinning frame, the reference is the outer side surface of a ring rail, the ring spinning yarn joint device is arranged on the track, so that the ring spinning yarn joint device moves according to a preset track, when yarn is broken in the spinning process, the ring spinning yarn joint device moves to a corresponding spindle position joint according to a yarn breaking alarm signal, the distance between the guide rail and the spinning frame is suitable for the joint action of the ring spinning yarn joint device, and the movement range of each device such as a yarn outlet device, a yarn winding device, a yarn lifting and guiding device, a yarn pressing device and the like, which is required to be covered by the joint, can be ensured. It is not excluded that the first moving platform 22 is mounted on an automatic guiding and transporting platform (for example, a moving platform such as an AGV and an AMR), so that the flexible movement of the ring spinning yarn splicing device can be realized, the mobility of the ring spinning yarn splicing device for performing automatic splicing operation is improved, at this time, the first moving platform can increase the degree of freedom of the movement in the horizontal direction perpendicular to the length of the spinning frame, when receiving a yarn breakage alarm signal, the automatic guiding and transporting platform moves to the position of a broken yarn spindle by means of a navigation system, and due to uneven ground and other reasons, a pose adjustment system is needed between the ring spinning yarn splicing device and the automatic guiding and transporting platform, for precisely adjusting the relative position between the ring spinning yarn splicing device and the spinning frame, and for adding the degree of freedom of swinging for the first moving platform is also needed to ensure the reliability of the splicing, and for this reason, a sensor for detecting the relative position of the ring spinning yarn splicing device and the spinning frame is also needed, and these are not ring spinning yarn splicing devices, and belong to the movement and adjustment system matched with the ring spinning yarn splicing device.

Embodiment 2 of a ring spun yarn splicing device of the present invention (see fig. 1 to 26):

this embodiment differs from embodiment 1 of the ring spun yarn splicing device in that:

the ring spinning yarn breakage detection device of the embodiment is added with a bead ring finding device (shown in fig. 4 and 10).

The steel wire ring finding device comprises a steel wire ring gripper 144, a steel wire ring gripper driving device and a steel wire ring positioning component, wherein the steel wire ring gripper 144 is a hollow cylindrical component which can be sleeved outside a cop, the diameter of the lower edge of the steel wire ring gripper is equal to that of the steel ring 42, the lower edge of the steel wire ring gripper can press the steel wire ring 43 on the steel ring,

The steel wire ring gripper driving device comprises a steel wire ring gripper rotating device, a steel wire ring Z-axis moving device and a steel wire ring Y-axis moving device, wherein the steel wire ring gripper rotating device comprises a gripper rotating stepping motor 1431, a gripper rotating transmission synchronous belt 1432 and a gripper rotating positioning bearing 1433, the steel wire ring Z-axis moving device comprises a steel wire ring Z-axis guiding component, a steel wire ring Z-axis driving component and a steel wire ring Z-axis platform 1416, the steel wire ring Z-axis guiding component comprises a steel wire ring Z-axis guiding 1414 which is arranged on a first moving platform 22 in the vertical direction, a steel wire ring Z-axis sliding block 1415 which is arranged along the steel wire ring Z-axis guiding sliding configuration, the steel wire ring Z-axis driving component comprises a steel wire ring Z-axis motor 1411 which is arranged on the first moving platform 22 and a steel wire ring Z-axis lead screw 1413 which is connected with a steel wire ring Z-axis motor shaft, the steel wire ring Z-axis platform 1416 is arranged on the steel wire ring Z-axis sliding block 5, the steel wire ring Z-axis guiding component is arranged on the steel wire ring Z-axis motor 1416, and the steel wire ring Z-axis sliding block 1413 is arranged on the steel wire ring Z-axis sliding block 1416, and the steel wire ring Z-axis sliding block 1416 is driven along the vertical direction of the steel wire ring Z-axis sliding block 1416, and the steel wire ring Z-axis sliding block 1416 is arranged along the steel wire ring Z-axis and the steel wire ring Z-axis sliding block and the steel wire ring sliding block. The Y-axis moving device comprises a Y-axis guiding component, a Y-axis driving component and a Y-axis platform 1426, wherein the Y-axis guiding component comprises a Y-axis guiding rail 1424 horizontally installed on the Z-axis platform 1416 in the direction perpendicular to the length direction of the spinning frame, a Y-axis sliding block 1425 slidingly configured along the Y-axis guiding rail, the Y-axis driving component comprises a Y-axis motor 1421 installed on the Z-axis platform 1416 and a Y-axis screw 1422 connected with the Y-axis motor shaft, the Y-axis platform 1426 is installed on the Y-axis sliding block 1425, the Y-axis screw nut 1423 is installed on the Y-axis platform 1426, and the Y-axis motor 1421 drives the Y-axis platform 1426 to move reciprocally in the direction perpendicular to the length direction of the spinning frame through the Y-axis screw 2 and the Y-axis screw nut 1423.

The bead ring positioning component is a component capable of blocking the bead ring, as shown in fig. 10, the bead ring stop lever 1434 (serving as the bead ring positioning component) is a rod-shaped component which is adjacent to the bead ring gripper 144 and is fixedly mounted below the bead ring Y-axis platform 1426, the distance between the bead ring stop lever 1434 and the rotation center of the bead ring gripper 144 is equal to the diameter of the ring, and when the bead ring gripper 144 drives the bead ring 43 to rotate, the rod-shaped bead ring positioning component blocks and stops the bead ring on one side of the ring away from the spinning frame.

When the bead ring needs to be found and positioned, the bead ring searching Z-axis moving device and the bead ring searching Y-axis moving device move cooperatively to enable the bead ring gripper 144 to move to a position above the bobbin 44 and coaxial with the bobbin, as shown in fig. 10. The lower end of the bead ring gripper 144 is a conical section, the end size is close to or slightly smaller than the inner diameter of the ring 42, and the surface of the conical section is elastically filled with silica gel or the like with a larger friction coefficient. The bead ring gripper 144 is driven by the bead ring Z-axis moving device to press against the inner side surface of the upper end of the ring 42 from top to bottom, so as to press the bead ring 43 and tilt the outer side, and the outer side tilting facilitates the hanging of the elastic joint yarn 1215. The gripper rotating stepper motor 1431 drives the traveler gripper 144 to rotate and friction drives the traveler 43 to rotate along the ring, and the traveler stop lever 1434 stops and stops the traveler 43 on the side of the ring away from the spinning frame (as shown in fig. 26).

In addition to using the blocking member as the bead ring positioning member, a bead ring detection sensor may be used as the bead ring positioning member. For example, a bead ring detection sensor mounted on the bead ring Y-axis platform 1426 for directly or indirectly detecting whether the bead ring moves to the side of the ring 42 far away from the spinning frame is used as a bead ring positioning component, the bead ring detection sensor can be divided into a contact type and a non-contact type, the bead ring detection sensor capable of detecting the bead ring has wide mature application in a broken end detection system, the non-contact type mainly comprises photoelectric type, inductive type, hall type and other sensors, or an image sensor is used for detecting the position of the bead ring in combination with image processing, and the contact type bead ring detection sensor is mechanically triggered when the bead ring 43 moves. The wire ring detecting sensor detects the moving position of the wire ring 43 in the rotation process of the wire ring gripper, and when the wire ring moves to the side of the ring away from the spinning frame, the wire ring gripper 144 stops rotating, and then the wire ring hanging process is performed.

If the lift guide hook device is mounted on the winding holder of the winding device, it is also necessary to mount a lift guide hook device on the bead ring Y-axis platform 1426, which is identical to the lift guide hook device mounted on the winding holder 134, for lifting the guide hook when the bead ring gripper is inserted into the cop. If the lift hook device is mounted on the first mobile platform 22, there is no need to separately mount the lift hook device on the bead ring device.

Embodiment 3 of a ring spun yarn splicing device of the present invention (see fig. 1 to 28):

The difference between this embodiment and the ring spinning yarn splicing device embodiment 2 is that in this embodiment, the cylindrical bead ring gripper 144 is replaced by a rod-shaped bead ring gripper 1440 (as shown in fig. 28), the rotation track of the rod-shaped bead ring gripper 1440 is cylindrical, the diameter of the lower end is approximately the same as that of the ring, the most part of the longitudinal rod is cut off in the circumferential direction of the bead ring gripper 144, the process of finding the bead ring by using the rod-shaped bead ring gripper 1440 is similar to the process of using the cylindrical bead ring gripper 144, the rotation center of the rod-shaped bead ring gripper 1440 is aligned with the center of the bobbin, then the rod-shaped bead ring gripper 1440 is lowered to the height of the lower end of the rod-shaped bead ring gripper 1440 to be close to the top surface of the ring, the rod-shaped bead ring gripper 1440 starts to rotate, the tail end of the rod-shaped bead ring gripper 1440 pushes the bead ring along the ring, when the bead ring rotates to contact with the bead rod 1434, the movement is stopped, and then the splice yarn is hung into the bead ring.

In order to improve reliability, the magnetic steel is arranged at the lower end of the rod-shaped steel wire ring gripper 1440, which is close to the steel collar, the magnetic steel at the tail end of the rod-shaped steel wire ring gripper 1440 catches the steel wire ring and drags the steel wire ring to move along the steel collar in the rotation process of the rod-shaped steel wire ring gripper 1440, in order to prevent the steel wire ring from being found due to the fact that the yarn head can push the steel wire ring to slide on the steel collar when the cop rotates, the rotation direction of the rod-shaped steel wire ring gripper is opposite to the rotation direction of the cop, and therefore the steel wire ring can be found even if the cop yarn head swings to cause the steel wire ring to slide on the steel collar.

In addition to directly using the bead ring block as the bead ring positioning member, in the case of using the rod-shaped bead ring gripper 1440, a sensor mounted on the bead ring Y-axis platform 1426 to detect the rotational position of the rod-shaped bead ring gripper 1440 may be used as the bead ring positioning member, and when detecting that the rod-shaped bead ring gripper 1440 rotates one full turn back to the side of the ring away from the spinning frame, it is considered that the bead ring has reached the side of the ring away from the spinning frame, the position of the bead ring is indirectly detected by detecting the rotational position of the rod-shaped bead ring gripper 1440, and even an angle sensor such as an encoder mounted on the gripper rotating stepper motor 1431 may be used as the bead ring detection sensor. It is not excluded that the magnetic steel is not installed at the lower end of the rod-shaped steel wire ring gripper, a section of flexible material is installed, and the steel wire ring is searched by rotating by contacting the top surface of the steel collar. It is also not excluded that the rod-shaped bead ring gripper adopts a triangular joint with the upper gate width and the lower face being plucked to increase its stability and rigidity.

Since the lowest position of the yarn guide hook 45 is higher than the top end of the yarn tube 44, in this embodiment, the rod-shaped bead ring grip 1440 is in a rod shape, the circumferential direction is not closed, and the initial position of the rotation is assumed to be at the position of the farthest from the spinning frame, and the bead ring device returns to the initial position after rotating for one turn, so in the process of moving from the position far away from the spinning frame to the direction approaching to the spinning frame, as long as the bead ring Y-axis platform 1426 and the grip rotation positioning bearing 1433 can pass through at the position higher than the top end of the yarn tube and do not interfere with the yarn guide hook, the rod-shaped bead ring grip 1440 cannot interfere with the yarn tube, and the bead ring device does not need to be provided with the yarn guide hook lifting device. Only when the bead ring gripper 144 of the bead ring device is in a higher cylindrical shape and the height cannot pass through the space between the guide hook and the top end of the bobbin to be sleeved outside the bobbin without lifting the guide hook, the guide hook device is required to be lifted, the height of the bead ring gripper 144 depends on whether an air ring is mounted on the spinning frame, if the air ring is mounted, the height of the bead ring gripper 144 must be higher than the height from the air ring to the top surface of the ring, otherwise, the bead ring cannot be found, if the spinning frame is not mounted with the air ring, the bead ring gripper 144 only needs to be in a short height, and in this case, if the guide hook is not lifted and the bead ring gripper can be sleeved outside the bobbin, the guide hook device is not required to be lifted.

In the embodiments 1 and 2 of the ring spinning yarn splicing device, the yarn guide opening 1216 is driven by the yarn guide opening swinging device to swing to be in the horizontal state in fig. 11 or the vertical state in fig. 14, when the yarn guide opening is in the horizontal state in fig. 11, the yarn guide opening 1216, the yarn holding device and the yarn guide tube 1211 are positioned on the same straight line, so that the yarn-taking-out clamping structure is convenient for clamping the yarn of the splice and winding the yarn of the splice into the yarn guide opening 1216, and when the yarn guide opening is in the vertical state in fig. 14, the yarn guide opening is convenient for being matched with the yarn winding holder 134 to wind the yarn of the splice onto the yarn winding holder 134, and in addition, when the steel wire ring and the winding roller are worn, the yarn guide opening also needs to swing to be in an angle direction inclined downwards than the horizontal. The yarn gripping device and the yarn cutting device may be fixedly mounted on the yarn guide Y-axis platform 1226 so that the yarn gripping device and the yarn cutting device are positioned in the same position as those in fig. 11, but do not swing with the yarn guide, and only the degree of freedom of the swinging of the yarn guide may be maintained. Although the degree of freedom of swinging of the yarn guide is preferably swinging about a horizontal axis in the longitudinal direction of the spinning frame, swinging about axes in other directions is not excluded. In addition to the swing, the degree of freedom in the vertical direction may be used instead of the degree of freedom in the swing of the yarn guide, and the function of the yarn guide may be realized.

The embodiment is to fixedly install the yarn holding device and the yarn cutting device on the yarn guiding Y-axis platform 1226, so that the yarn holding device and the yarn cutting device are consistent with the positions of the yarn holding device and the yarn cutting device in fig. 11, the yarn holding device and the yarn cutting device do not swing along with the yarn guiding mouth, meanwhile, the degree of freedom of swinging of the yarn guiding mouth is replaced by the degree of freedom of movement of the yarn guiding mouth in the vertical direction relative to the yarn holding device, specifically, the yarn guiding mouth only keeps an open ring-shaped part of the end part, the yarn guiding mouth is driven to move up and down relative to the vertical direction of the yarn cutting device by a vertical direction driving device installed on the yarn guiding Y-axis platform 1226, when the yarn guiding mouth is located at the same height as the yarn holding device, the yarn cutting device and the yarn guiding tube 1211, the yarn holding structure is convenient for holding the end part of the yarn guiding mouth and winding the yarn guiding mouth, when the yarn guiding mouth is lifted to be higher than the yarn holding device in the vertical direction, the yarn guiding mouth can be pulled to wind around the yarn winding holder, and the yarn guiding mouth can also be lowered to a position lower than the yarn holding device and pass through the steel wire and the winding roller. The driving device mounted on the yarn guiding Y-axis platform 1226 for driving the yarn guiding opening to move in the vertical direction can adopt a linear motion mechanism or device such as a reciprocating belt, a micro linear motor, an air cylinder and the like.

Example 4 of a ring spun yarn splicing device of the present invention:

Since the lowest position of the yarn guide hook is higher than the top end surface of the yarn bobbin and the highest position of the yarn guide hook is also determined, the yarn guide hook lifting device is mounted on the first moving platform 22, the yarn guide hook lifting component is a rod-shaped or plate-shaped component which can be inserted below the yarn guide hook to lift the yarn guide hook, the yarn guide hook lifting driving mechanism drives the yarn guide hook lifting component to have the freedom degree of horizontal movement in the vertical direction and the direction perpendicular to the length direction of the spinning frame, and when the yarn guide hook lifting is required, the yarn guide hook lifting driving mechanism drives the yarn guide hook lifting component to be lifted to the height which can be inserted between the yarn guide hook and the top surface of the yarn bobbin, and then drives the yarn guide lifting component to horizontally move to the position which is below the yarn guide hook and is used for lifting the yarn guide hook to a position which does not affect the sleeving of the winding holder to the outer side of the yarn guide ring and does not affect the sleeving of the yarn guide ring device on the outer side of the yarn bobbin. The proposal is provided with the yarn lifting and guiding hook device independently, and the yarn winding device and the wire ring finding device do not need to be provided with the yarn lifting and guiding hook device independently.

Embodiment 5 of a ring spun yarn splicing device of the present invention (see fig. 1 to 27):

As shown in fig. 27, in this embodiment, the yarn pressing member 111 in the ring spun yarn splicing device of embodiment 2 is replaced by a yarn feeding ring member 151, and the yarn feeding ring member 151 has a Y-shaped rod-like structure and is mounted on the first moving platform by a double-rod cylinder, and has a degree of freedom of movement in a horizontal direction perpendicular to the length of the spinning frame with respect to the first moving platform. When the yarn winding holder is required to be retracted, the air cylinder drives the yarn withdrawing member 151 to move to the position close to the yarn winding holder in the horizontal direction of the spinning machine, the yarn withdrawing member 151 is positioned at the upper part of the yarn winding holder outside yarn winding, and when the yarn winding holder 134 moves upwards, the yarn withdrawing member 151 stops the yarn winding, in which case, the yarn withdrawing member 151 only needs to have one degree of freedom in horizontal movement perpendicular to the length direction of the spinning machine, or the yarn withdrawing member 151 can actively move downwards in the vertical direction to push the yarn winding from the yarn winding holder, in which case, the yarn withdrawing member 151 also needs to have one degree of freedom in the vertical direction.

In addition to the first moving platform, the yarn-withdrawing member may be mounted on the yarn-winding holder 134, specifically, a yarn-withdrawing member is mounted on the yarn-winding holder by a yarn-withdrawing member-pushing handle, which is a horseshoe-shaped member with 3 holes, the three holes of the yarn-pushing handle are respectively sleeved on three cantilever rods 1341 supporting the yarn-winding of the connector on the yarn-winding holder, the yarn-withdrawing member-pushing handle is guided by the three cantilever rods on the yarn-winding holder, and is pushed by a cylinder mounted on the yarn-winding holder in the vertical direction to reciprocate along the length direction (vertical direction) of the three cantilever rod members, and the yarn-winding member on the yarn-winding holder is pushed down from the yarn-winding holder when the yarn-pushing handle moves down to its limit position. The coil pushing hand is not limited to the horseshoe shape as long as the joint coil can be pushed down from the winding holder when moving down.

Example 6 of a ring spun yarn splicing device of the present invention (see fig. 1 to 25):

In order to more stably realize these actions when the yarn is threaded into the bead ring and the yarn-receiving yarn is threaded down from the yarn-receiving yarn ring wound around the outside of the yarn-winding holder, it is preferable to know the position of the ring plate in the vertical direction with respect to the first movable platform 22 with accuracy. In addition, both the withdrawal of the joint yarn loop from the yarn winding holder and the winding of the yarn guide hook can be performed according to the position of the ring plate detected by the ring plate detecting device.

The ring plate detection device can adopt one of the following schemes.

First, as shown in fig. 1 and 2, the ring plate detecting device includes a follower ring plate gripper 214 (as a follower), a follower driving device, and a ring plate detecting member;

The follow-up ring plate gripper 214 is a rod-shaped component arranged on the first moving platform through a follow-up component driving device, the follow-up ring plate gripper 214 is a Z-shaped structural component, the front end of the follow-up ring plate gripper extends out towards the spinning frame, the middle part of the follow-up ring plate gripper is connected with the gripper lifting slide block 213, and the rear end of the follow-up ring plate gripper is a horizontal surface which is easy to detect;

The follower driving device drives the follower to have a motion degree of freedom in the vertical direction relative to the first moving platform; the follower driving device comprises a gripper lifting cylinder 211, a gripper lifting guide rail 212 and a gripper lifting slide block 213, wherein the gripper lifting cylinder 211 and the gripper lifting guide rail 212 are vertically and fixedly arranged on the box body base 20, the cylinder rod can extend upwards, the cylinder rod end of the gripper lifting cylinder 211 is propped against the lower surface of the tail end of the follower ring plate gripper 214, but the cylinder rod of the gripper lifting cylinder 211 is not connected with the follower ring plate gripper 214, the gripper lifting slide block 213 is connected with the follower ring plate gripper 214 and is arranged on the gripper lifting guide rail 212 and can freely move along the vertical direction, the gripper lifting cylinder 211 is used as the follower driving device, only the effect of lifting the follow-up ring plate gripper 214 (as a follow-up member) is supported in the vertical direction, the follow-up ring plate gripper 214 is lowered by its own weight, when the follow-up ring plate gripper 214 starts to fall from a highest limit position higher than the ring plate in the vertical direction, the follow-up ring plate gripper 214 can ride on the ring plate 41 in the process of falling by the own weight, the ring plate 41 supports the follow-up ring plate gripper 214 to move up and down along with the ring plate 41, and when a single ingot breakage detection sensor is mounted on the ring plate 41, the follow-up ring plate gripper 214 may ride on the single ingot breakage detection sensor;

The ring plate detecting component is a ring plate detecting sensor 215 mounted on the gripper elevating guide rail 212, and the ring plate detecting sensor 215 of this embodiment is an ultrasonic distance sensor for detecting the distance between the horizontal surface of the rear end of the follower ring plate gripper 214 and the first moving platform, so as to detect the relative position between the follower component moving up and down along with the ring plate and the first moving platform in the vertical direction, or the ring plate detecting sensor 215 may be mounted on the horizontal surface of the rear end of the follower ring plate gripper 214, so as to detect the distance between the horizontal surface of the rear end of the follower ring plate gripper 214 and the first moving platform.

When the yarn spindle breaks, the first moving platform 22 moves to the corresponding yarn spindle position along the length direction of the spinning frame, the cylinder rod of the gripper lifting cylinder 211 stretches out upwards to convey the follow-up ring plate gripper 214 to the highest position (higher than the highest position of the ring plate 41), then the first moving platform 22 moves towards the spinning frame to be close to the spinning frame, the cylinder rod of the gripper lifting cylinder 211 retracts, the follow-up ring plate gripper 214 descends along the vertical direction by virtue of the self weight of the follow-up ring plate gripper until the follow-up ring plate gripper is put on the ring plate 41, the follow-up ring plate 41 moves in a step-up mode, and the ring plate detection sensor 215 determines the relative position between the ring plate gripper 214 and the first moving platform by detecting the distance between the follow-up ring plate gripper 214 and the first moving platform for hanging a steel wire ring and other operations.

If the first moving platform 22 does not have a degree of freedom for horizontal movement in a direction perpendicular to the length direction of the spinning frame, the follower driving device needs to set a degree of freedom for horizontal movement in a direction perpendicular to the length direction of the spinning frame for driving the follower ring rail grip 214 away from and toward the spinning frame, so as to avoid interference between the follower ring rail grip 214 and the spinning frame when the ring spinning frame joint device moves to the head and tail of the spinning frame in the length direction of the spinning frame.

The steel collar plate detection component can adopt a contact type or non-contact type sensor, the common contact type sensor comprises a sliding arm resistance type displacement sensor, a stay wire type displacement sensor, a grating ruler and the like, when the contact type sensor is adopted, a movable component and a sensor structure body of the contact type sensor are respectively arranged on a first movable platform and a follow-up component, the common non-contact type sensor comprises an ultrasonic displacement sensor, a laser displacement sensor and the like, and the non-contact type sensor can be arranged on the first movable platform or the follow-up component.

Second, instead of the method of detecting the distance between the ring plate follower and the first moving platform, a sensor mounted on the first moving platform may be used to directly detect the position of the ring plate, as shown in fig. 3, a ring plate detecting sensor 215 is fixedly mounted on the first moving platform 22 through a ring plate detecting bracket 21, the ring plate detecting sensor 215 is a laser ranging sensor, and the relative position of the ring plate with respect to the first moving platform is detected. Alternatively, an image sensor (camera) mounted on the first moving platform may be employed as the ring plate detecting means, and the positional relationship between the ring plate and the first moving platform may be determined by analyzing an image acquired by the image sensor (camera) to detect the positional relationship between the ring plate and the camera, since the positional relationship between the camera and the first moving platform is known.

The coordinate system in the drawing of the ring spinning yarn splicing device adopts a right-hand Cartesian coordinate system. The driving device in all embodiments can be replaced by common components and mechanisms with the same functions, for example, the movement driven by a cylinder can be changed into the driving of a linear motor, a rotary motor screw rod, a motor cam push rod, an electromagnet and the like, and the guiding can be realized by adopting the guiding of an optical axis, a sliding block or a linear guide rail and the like, which belong to common knowledge in the field and are not repeated. The invention is not limited to the embodiments discussed above, and other variants can be deduced from the invention by a person skilled in the art, which variants also belong to the subject matter of the invention.
