Background
In the textile industry, a ring spinning frame is one of the most important production devices, and after a yarn break occurs in the spinning frame, a vehicle stop worker is generally required to pull a cop off from a spindle, find a spun yarn head on the cop, insert the cop onto the spindle after the head passes through a steel wire ring, and splice the spun yarn to a sliver 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 exist between the spun yarns. The process of jointing is complex, and the automation of the jointing process is not easy to realize.
When ring spun yarn is fully spun and doffed and then starts to spin a new doffed yarn, the spindle position without end remaining needs to be stopped by a worker to manually yarn, when the worker stops spinning, the end of the yarn is hung in a steel wire ring, one end of the yarn is wound on a yarn tube for one circle (or may not be limited to one circle) and then is lightly pulled to wind the yarn tube by utilizing the rotation of the yarn tube, the end of the yarn can be close to or pressed on the surface of the yarn tube, the yarn is wound on the cop tube by the rotation of the yarn tube, once the yarn is effectively wound on the yarn tube, the other end of the yarn must be quickly erected to pass through a yarn guide hook part in time, the yarn is twisted by the rotation of the steel wire ring, the other end of the yarn cannot be kept in the radial direction of the cop tube, or the yarn is quickly wound on the yarn tube and pulled to be broken. The spinning-in operation of the ring spun yarn belongs to common knowledge in the industry, and is not described again, but the spinning-in operation is never used for a joint after the end of the spun yarn is broken in the industry.
Although an automatic joint device for a ring spinning frame has been developed at present, the automatic joint of ring spinning spun yarns can be completed, and some patents related to the automatic joint of ring spinning exist at home and abroad, the practical feasibility, the operation success rate and the like have obvious problems, on one hand, the automatic joint success rate is not high enough, the joint time consumption is long, especially, the success rate of finding the broken ends on the cop after the ends of the spun yarns are broken is not high enough, so that the joint success rate of the automatic joint technology with the end finding link is low, and on the other hand, the joint device has a complex structure and high price, and is not suitable for large-scale popularization and application.
In recent years, a fine winding and unwinding technology and an automatic winding and unwinding technology matched with an automatic winder are gradually mature and popularized and applied in a large scale, supposing that a bobbin yarn comprises multiple sections of discontinuous spun yarns, when winding is carried out in a winding process, a section of spun yarn finally spun on the bobbin yarn is firstly wound on a cheese, then the bobbin yarn is discharged by the winder, is conveyed to an automatic winding and unwinding position by an automatic conveying system of the winder for rewinding, then enters a doffing station again for rewinding, a second section of spun yarn is wound on the cheese, and the process is repeated until all the spun yarns on the bobbin yarn are wound. That is to say, the automatic empty bobbin recognition and sorting, automatic bobbin yarn conveying, automatic bobbin yarn spinning and automatic bobbin yarn feeding systems matched with the existing automatic bobbin winders have the capability of automatically processing spun yarn bobbins which are spun by sections.
In view of the above problems and backgrounds, the present invention discloses a device for winding joint yarn onto a bobbin, which is used for winding the joint yarn onto the bobbin to realize joint, and is beneficial to reducing the complexity of automatic joint, and does not need operations such as tube drawing and yarn end finding, so that the operation is more stable and reliable, the device is beneficial to realizing automatic joint after ring spinning yarn breakage, and can also be used for yarn threading under the condition that the end is not successful after doffing spinning.

The lowest height of a yarn guide hook of a ring spinning frame is higher than the top end of a bobbin, if a winding retainer 134 and joint yarns wound on the winding retainer can extend into the top end of the bobbin between the yarn guide hook and the top end of the bobbin and do not interfere with the bobbin and the yarn guide hook, the yarn guide hook does not need to be lifted, if a balloon ring is installed on the ring spinning frame, the length of the winding retainer 134 in the vertical direction cannot be too short, otherwise, the winding retainer cannot extend downwards to a stage lifting section on the bobbin yarn above the balloon ring, and under the condition, if the yarn guide hook is not lifted, the winding retainer cannot be sleeved outside the bobbin, and otherwise, the winding retainer interferes with the yarn guide hook. For this reason, a yarn guide hook lifting device is mounted on the winding holder to lift the yarn guide hook when the winding holder is fitted to the bobbin.
The yarn lifting hook device comprises a yarn lifting hook part and a yarn lifting hook driving mechanism (as shown in figure 10),
lift the guide hook part including rotating horizontal pole 1371, the horizontal pole rotates the frame 1372 and connects and rotates horizontal pole 1371 and lift the extension spring that resets of guide hook cylinder frame 1374, it rotates horizontal pole 1371 and horizontal pole and rotates frame 1372 through hinged joint, both can realize relative 90 degrees rotations, the extension spring that resets makes and rotates horizontal pole 1371 in the extreme position shown in fig. 10, when spool 44 gives and rotates horizontal pole 1371 towards the effort that is close the spinning frame direction, rotate the one end orientation that horizontal pole 1371 kept away from the swing axis and swing towards the direction that is close the spinning frame, when spool 44 removes for the effort that rotates horizontal pole 1371, make by the extension spring that resets and rotate horizontal pole 1371 and resume to the extreme position shown in fig. 10.

if the yarn lifting hook device is not provided with the rotating cross bar 1371, but is a fixed plate-shaped or rod-shaped component which cannot swing, the winding retainer needs to be lifted to the height that the winding retainer 134 is higher than the bobbin 44 before being withdrawn towards the direction far away from the spinning frame, otherwise, the winding retainer can interfere with the bobbin during the withdrawal towards the direction far away from the spinning frame, and similarly, if the winding retainer is of a cylindrical structure, the winding retainer needs to be lifted to the height that the winding retainer does not interfere with the bobbin before being withdrawn towards the direction far away from the spinning frame, and then the winding retainer can be horizontally withdrawn towards the direction far away from the spinning frame.
The yarn lifting and guiding hook device is installed on the yarn winding retainer 134 through the yarn lifting and guiding hook air cylinder base 1374, when the yarn winding retainer needs to be sleeved on the outer side of the bobbin, the yarn winding retainer drives the yarn lifting and guiding hook device to move to the rotary cross rod 1371 below the yarn guiding hook, the height above the bobbin, the air cylinder rod lifting and guiding hook air cylinder 1375 extends out, the drive cross rod rotates the base 1372 to move below the yarn guiding hook, when the yarn winding retainer moves upwards, the rotary cross rod 1371 lifts the yarn guiding hook, and meanwhile, the yarn winding retainer can be close to the direction of a spinning machine and cannot interfere with the yarn guiding hook.
By means of the mechanism and the device, the working process of the device for winding the joint yarn on the bobbin is as follows:
the elastic joint yarn 1215 is held by a yarn taking head clamping structure on a winding holder, the process of holding the elastic joint yarn 1215 by the yarn taking head clamping structure is shown in fig. 5 and 6, the elastic joint yarn 1215 is wound into yarn loops (shown in fig. 7) on the outer sides of three cantilever rods 1341 of the winding holder 134, the number of the wound yarn loops is more than one, and the yarn head clamped by the yarn taking head clamping structure is guaranteed to be pressed by the middle section of the elastic joint yarn 1215. 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 yarn winding retainer, and the tail end of the elastic joint yarn 1215 is held by the yarn picking ring component (as shown in figures 8 and 9) so as to keep the shape of the loop formed by the elastic joint yarn 1215 unchanged. At this point, preparation of the pieced yarn before piecing is completed.
When a certain spindle position breaks or an empty bobbin needs to be pieced, the piecing device moves to the corresponding spindle position along the length direction of the spinning frame, the yarn winding device moves forward along the Z axis to a position where the rotating cross bar 1371 is slightly higher than the top of the bobbin 44 (as shown in fig. 10), the cylinder rod of the yarn guide lifting cylinder 1375 in the yarn guide lifting device extends out, the rotating cross bar 1371 is pushed to move towards the direction close to the spinning frame to insert the rotating cross bar 1371 below the yarn guide 45, the yarn winding device is driven by the yarn winding moving device to simultaneously move forward along the Z axis and the Y axis to lift the yarn guide up until a loop wound by the elastic piecing yarn 1215 on the yarn winding retainer 134 is sent to the position right above the bobbin 44, and the yarn winding Z axis moving device drives the yarn winding retainer 134 to move downwards to a height position close to the upper surface of the steel collar 42.
In the process that the winding retainer 134 moves downwards outside the bobbin, joint yarns wound on the outer side of the winding retainer are easy to scrape and rub with yarns on the bobbin, so that joint yarn coils wound on the outer side of the winding retainer are blocked to slide upwards along the three cantilever rods 1341 of the winding retainer and then are gathered together, and the joint yarn coils are not beneficial to dispersedly covering broken ends of the original bobbin yarn.
As shown in fig. 11 and 12, the yarn pressing member 111 moves to a yarn pressing station corresponding to the height of the yarn loop on the yarn winding holder under the driving of the yarn pressing Z-axis moving device, and the yarn pressing member 111 is rapidly pressed on the three vertical rod surfaces of the yarn tube 44 and the yarn winding holder 134 by the yarn pressing Y-axis moving device to press and fix the yarn loop, fig. 12 is a schematic view from bottom to top as seen in the vertical direction, the yarn pressing member 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 loop clamping cylinder 1351 in the yarn picking loop member and the yarn head clamping cylinder 136in the yarn picking head clamping structure are opened simultaneously, the head of the elastic joint yarn 1215 and the tail end of the yarn loop are released, at this time, the rod of the yarn winding Z-axis lifting cylinder 1317 extends out to drive the yarn winding holder 134 to rapidly move forward (vertically upward), and the loop formed by the elastic joint yarn winding head 1215 is not pressed by the yarn pressing member 111 and does not follow the upward movement of the yarn winding holder 1317, and the elastic joint yarn loop is wrapped on the surface of the yarn tube 44 and the yarn end of the yarn spinning head is not wrapped by the elastic joint 1215. Since the winding holder has a gap between the two cantilever bars 1341 close to the spinning frame for passing through the bobbin and the rotating crossbar 1371 is arranged on the lifting yarn hooking device, after the pieced yarn ring on the winding holder is separated from the winding holder, the yarn pressing part 111 and the winding holder 134 withdraw from the spinning area in the direction away from the spinning frame so as not to affect the subsequent piecing operation. If the yarn winding retainer is not provided with the rotating cross bar 1371, the yarn winding retainer needs to be lifted to the height that the yarn winding retainer part is higher than the bobbin before being withdrawn in the direction far away from the spinning frame, otherwise, the yarn winding retainer part is interfered with the bobbin during the withdrawal in the direction far away from the spinning frame, and similarly, if the yarn winding retainer is of a cylindrical structure, the yarn winding retainer needs to be lifted to the height that the yarn winding retainer part does not interfere with the bobbin before being withdrawn in the direction far away from the spinning frame, and then the yarn winding retainer part can be horizontally withdrawn in the direction far away from the spinning frame. At this point, the stable winding of the yarn around the bobbin 44 is completed. Example 2 of a device for winding a joint yarn onto a bobbin of the present invention (see fig. 1 to 13):
as shown in fig. 13, the yarn pressing member 111 of embodiment 2 is replaced by a yarn withdrawal ring member 151 in this embodiment, and the yarn withdrawal ring member 151 is of 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 pieced yarn loops wound on the outer side of the winding retainer need to be withdrawn, the air cylinder drives the yarn withdrawal loop component 151 to move forwards to the position of the winding retainer towards the Y axis, the yarn withdrawal loop component 151 is positioned at the upper part of the pieced yarn loops on the outer side of the winding retainer, and when the winding retainer 134 moves upwards, the yarn withdrawal loop component 151 blocks the yarn loops, so that the yarn withdrawal loop component 151 only needs to move horizontally in the Y direction for one degree of freedom; alternatively, the loop removing member 151 may be moved downward in the vertical direction to push the loop up from the yarn winding holder, and in this case, the loop removing member 151 needs to have a degree of freedom in the vertical Z direction.
The yarn pressing component can also be arranged on the yarn winding retainer, and specifically comprises the following components: a yarn ring pushing hand is arranged on the winding yarn retainer to serve as a yarn pressing part, the yarn ring pushing hand is a horseshoe-shaped part with 3 holes, the three holes in the yarn ring pushing hand are respectively sleeved on the three cantilever rods 1341, the yarn ring pushing hand is guided by the three cantilever rods on the winding yarn retainer and pushed by a cylinder arranged on the winding yarn retainer in the vertical direction to reciprocate along the length direction (the vertical direction) of the three cantilever rods, and when the yarn ring pushing hand moves downwards to the limit position of the yarn ring pushing hand, a yarn ring on the winding yarn retainer is pushed down from the winding yarn retainer. The loop pusher is not limited to a horseshoe shape as long as it can push the yarn splicing loop from the yarn winding holder while moving downward.
The coordinate system in the figure is a right-handed cartesian coordinate system. The driving devices in all embodiments can be replaced by common parts and mechanisms with the same functions, for example, the movement driven by the cylinder can be changed into driving by a linear motor, a rotating motor and a lead screw, a motor and a cam ejector rod, an electromagnet and the like, and the guiding can adopt guiding such as an optical axis, a sliding block or a linear guide rail and the like, which belong to the common knowledge in the field and are not described again. The invention is not limited to the embodiments discussed above, and a person skilled in the art can deduce other variants from the invention, which also belong to the subject matter of the invention.
