Background
In the textile industry, a ring spinning frame is one of the most important production devices, after a yarn breakage occurs in the spinning frame, a blocking machine is generally required to pull a cop from a spindle, find a yarn end of the spun yarn on the cop, insert the cop onto the spindle after the yarn end passes through a bead ring, and splice the spun yarn to a whisker strip output by a front roller after passing through a yarn guide hook, so that a tube of spun yarn is a continuous spun yarn no matter how many joints are arranged between the tube of spun yarn and the yarn. The jointing process is complex and is not suitable for automation.
When ring spinning yarn starts spinning a new doff after full doffing and doffing, a blocking worker needs to manually produce a yarn spindle position without a head, when the blocking worker produces the yarn spindle, one end of the yarn spindle is hung on a bead ring and then wound on a bobbin by a circle (possibly not limited to a circle) and then slightly pulled, the yarn spindle can be wound by utilizing the rotation of the bobbin, the tail end of the yarn spindle can be close to or pressed on the surface of the bobbin, the yarn spindle rotates to wind the yarn spindle onto the bobbin, once the yarn spindle is effectively wound onto the bobbin, the other end of the yarn spindle must be quickly erected in time to pass through a yarn guiding hook position, the yarn spindle is twisted by the rotation of the bead ring, and the other end of the yarn spindle cannot be kept in the radial direction of the bobbin, otherwise, the yarn spindle is quickly wound onto the bobbin and is broken. The spinning operation of the ring spun yarn belongs to common knowledge in the industry, and is not repeated, but the spinning operation is never used for the joint after the spinning breakage in the industry.
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 device for winding a connector yarn onto a spool, which is used for winding the connector yarn onto the spool to realize the connector, is beneficial to reducing the complexity of automatic connector, does not need operations such as tube drawing, yarn head finding and the like, has more stable and reliable work, is beneficial to realizing the automatic connector after the breakage of the ring spinning yarn, and can also be used for the connector generation under the condition of unsuccessful head remaining after doffing is finished.

the yarn lifting and guiding hook component comprises a rotating cross rod 1371, a cross rod rotating base 1372 and a reset tension spring for connecting the rotating cross rod 1371 with a yarn lifting and guiding hook cylinder base 1374, the rotating cross rod 1371 and the cross rod rotating base 1372 are connected through a hinge, the rotating cross rod 1371 and the cross rod rotating base 1372 can rotate by 90 degrees relatively, the reset tension spring enables the rotating cross rod 1371 to be in the limit position shown in fig. 10, when the spool 44 applies force to the rotating cross rod 1371 towards the direction close to the spinning frame, one end, far away from the swinging axis, of the rotating cross rod 1371 swings towards the direction close to the spinning frame, and when the force applied to the rotating cross rod 1371 by the spool 44 is removed, the rotating cross rod 1371 is restored to the limit position shown in fig. 10 through the reset tension spring.
The yarn lifting and guiding hook driving mechanism comprises a yarn lifting and guiding hook cylinder 1375 and a cylinder guiding guide rail 1373 which are arranged on a yarn lifting and guiding hook cylinder base 1374, wherein the yarn lifting and guiding hook cylinder 1375 is arranged and fixed in the yarn lifting and guiding hook cylinder base 1374, the cylinder guiding guide rail 1373 is parallel to a cylinder rod, and the yarn lifting and guiding hook component is pushed to horizontally reciprocate along the direction perpendicular to the length direction of the spinning frame by extending and retracting the cylinder rod;
if the rotating cross bar 1371 is not arranged on the yarn lifting guide hook device, but a fixed plate-shaped or rod-shaped component which cannot swing is needed to lift the yarn winding retainer to the height higher than the yarn winding retainer 134 than the yarn tube 44 before the yarn winding retainer withdraws from the spinning frame, otherwise, the yarn winding retainer interferes with the yarn tube during the process of withdrawing from the spinning frame, and if the yarn winding retainer is in a cylindrical structure, the yarn winding retainer can be withdrawn horizontally from the spinning frame after the yarn winding retainer is lifted to the height not interfering with the yarn tube before the yarn winding retainer withdraws from the spinning frame.
The yarn lifting guide hook device is mounted on the yarn winding holder 134 through the yarn lifting guide hook cylinder base 1374, when the yarn winding holder needs to be sleeved outside the yarn tube, the yarn winding holder drives the yarn lifting guide hook device to move to a height that the rotary cross rod 1371 is positioned below the yarn guiding hook and above the yarn tube, the cylinder rod of the yarn lifting guide hook cylinder 1375 stretches out, the rotary cross rod base 1372 is driven to move below the yarn guiding hook, and when the yarn winding holder moves upwards, the rotary cross rod 1371 lifts the yarn guiding hook, and meanwhile the yarn winding holder can approach to the direction of the spinning frame without interference with the yarn guiding hook.
By means of the above mechanism and device, the work flow of the device for winding the connector yarn onto the yarn tube is as follows:
the elastic joint yarn 1215 is held by the yarn taking head holding structure on the yarn winding holder, and the process of holding the elastic joint yarn 1215 by the yarn taking head holding structure is shown in fig. 5 and 6, the elastic joint yarn 1215 is wound into a yarn loop (shown in fig. 7) on the outer sides of three cantilever rods 1341 of the yarn winding holder 134, the number of the wound yarn loop is larger than one, and the middle section of the elastic joint yarn 1215 is ensured to press the yarn end held by the yarn taking head holding structure. After the winding is finished, the elastic joint yarn 1215 passes through the positioning joint yarn structure of the yarn picking ring component outside the winding holder, and the tail end of the elastic joint yarn 1215 is held by the yarn picking ring component (as shown in fig. 8 and 9) so as to keep the shape of the yarn ring wound by the elastic joint yarn 1215 unchanged. Thus, the preparation of the yarn before the yarn splicing is completed.
When a certain spindle position is broken or an empty bobbin needs to be spun, the joint device moves to the position corresponding to the spindle position along the length direction of the spinning frame, the yarn winding device moves forward to a position slightly higher than the top of the bobbin 44 along the Z axis (as shown in fig. 10), a cylinder rod of a yarn guiding hook lifting cylinder 1375 in the yarn guiding hook lifting device stretches out, the rotating cross rod 1371 is pushed to move towards the direction close to the spinning frame to insert the rotating cross rod 1371 under the yarn guiding hook 45, the yarn winding device is driven by the yarn winding moving device to move forward along the Z axis and forward along the Y axis to lift the yarn guiding hook until a yarn ring wound by an elastic joint yarn 1215 on the yarn winding holder 134 is conveyed to a position right above the bobbin 44, and the yarn winding Z axis moving device drives the yarn winding holder 134 to move downwards to a height position close to the upper surface of the steel collar 42.
In the process that the yarn winding holder 134 moves downwards outside the yarn tube, the yarn joint around the yarn winding holder is easy to scratch with the yarn on the yarn tube, so that the yarn loops of the yarn joint around the yarn winding holder are blocked to slide upwards along the three cantilever rods 1341 of the yarn winding holder and then are concentrated together, and the yarn loops are not beneficial to scatter to cover broken ends of the original cop.
As shown in fig. 11 and 12, the yarn pressing part 111 is driven by the yarn pressing Z-axis moving device to move to a yarn pressing station with the same yarn coil height on the yarn winding holder, and the yarn pressing part 111 is rapidly pressed and fixed on the yarn tube 44 and the three upright rod surfaces of the yarn winding holder 134 by the yarn pressing Y-axis moving device, fig. 12 is a schematic view from bottom to top in the vertical direction, the yarn pressing part 111 presses the elastic joint yarn 1215 wound on the outer side of the yarn winding holder 134 from the outer side of the triangle formed by the three cantilever rods on the yarn winding holder 134, the yarn coil clamping cylinder 1351 in the yarn picking coil part and the yarn end clamping cylinder 1361 in the yarn end picking clamping structure are simultaneously opened, the yarn end and the tail end of the yarn loop of the elastic joint yarn 1215 are released, at this time, the cylinder rod of the yarn winding Z-axis lifting cylinder 1317 extends to drive the yarn winding holder 134 to move forward in the Z-axis direction (vertically upwards), the yarn loop wound by the elastic joint yarn 1215 is pressed by the yarn pressing component 111 and does not move upwards along with the yarn winding holder 134, the yarn loop wound by the elastic joint yarn 1215 is enveloped on the surface of the yarn tube 44, and the yarn end part of the elastic joint yarn 1215 and the broken end envelop of the original yarn are enveloped inside the yarn loop, so that normal spinning is not influenced due to the centrifugal force of the yarn when spinning. Since the gap between the two cantilever rods 1341 of the winding holder near the spinning frame is enough to pass through the yarn tube, and the rotary cross rod 1371 is arranged on the yarn lifting guide hook device, after the yarn splicing ring on the winding holder is separated from the winding holder, the yarn pressing component 111 and the winding holder 134 withdraw from the spinning area far away from the spinning frame so as not to influence the subsequent yarn splicing 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. The yarn is wound onto the bobbin 44 to thereby finish the stable winding. Example 2 of the device for winding a yarn splicing around a bobbin according to the present invention (see fig. 1 to 13):
as shown in fig. 13, in this embodiment, the yarn pressing member 111 in embodiment 2 is replaced by a yarn feeding member 151, and the yarn feeding member 151 has a "Y" -shaped rod-like structure, and is driven by a double rod cylinder to have a degree of freedom in movement in the Y direction. When the yarn receiving ring wound on the outer side of the yarn winding holder is required to be withdrawn, the cylinder drives the yarn receiving ring component 151 to move forward to the position of the yarn winding holder towards the Y axis, the yarn receiving ring component 151 is positioned at the upper part of the yarn receiving ring on the outer side of the yarn winding holder, and when the yarn winding holder 134 moves upwards, the yarn receiving ring component 151 is required to receive the yarn receiving ring, and in this case, the yarn receiving ring component 151 only needs to move horizontally in the Y direction by one degree of freedom; alternatively, the yarn winding holder may be pushed up and down by the yarn winding member 151 being moved actively in the vertical direction, and in this case, the yarn winding member 151 needs to have a degree of freedom in the vertical Z direction.
The yarn pressing component can be arranged on the yarn winding retainer, specifically: the yarn winding holder is provided with a yarn coil pushing handle as a yarn pressing component, the yarn coil pushing handle is a horseshoe-shaped component with 3 holes, the three holes of the yarn coil pushing handle are respectively sleeved on three cantilever rods 1341, the yarn coil pushing handle is guided by the three cantilever rods on the yarn winding holder and is pushed by an air cylinder arranged on the yarn winding holder in the vertical direction to reciprocate along the length direction (vertical direction) of the three cantilever rod components, and when the yarn coil pushing handle moves downwards to the limit position, the yarn coil on the yarn winding holder is pushed down from the yarn winding holder. 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.
The coordinate system in the figure 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.
