Description

Technical part

The invention belongs to the technical field of textile machinery and relates to improvements in an automatic yarn winding machine and a yarn spooling method, particularly a tub type yarn winding machine and a yarn spooling method.

State of the art

In known tub thread winding machines, bobbins for a single spindle are supplied via a flat belt. During unwinding from a single spindle, when the thread clearer cuts the thread or is replaced with a new bobbin, a small suction nozzle is driven to be displaced downward to suck the thread end cut by a scissor unit. But in some cases (such as the downward displacement of the small suction nozzle encounters resistance or parts of the small suction nozzle are blocked), the small suction nozzle cannot suck the thread. Under these circumstances, the thread end falls off and a new bobbin must be used. The bobbin with the dropped thread end of the bobbin is loaded on a front flat belt, and conveyed by the front flat belt back to a bobbin processing devicebobbin processing device to take up a new thread end, and then the bobbin with the new thread is passed under the single spindle through a rear Flat strip conveyed to the single spindle for winding. When the thread end falls, because the length of the thread end is greater than the height of the bobbin, the thread end may fall on the front flat band and wrap around other components, but at the same time, the bobbin is displaced by the front flat band, and therefore the bobbin will be during of unwinding is shifted forward, resulting in a situation where a very long thread is wound up in a random manner whenever it passes the bobbin. The unwound threads interfere with the normal operation of the bobbin feed system and increase maintenance requirements.

A yarn threading process and a bobbin changing process of a typical tub-type yarn winding machine according to the prior art are in FIGS 1 until 4 shown. 1 Fig. 12 is a schematic representation of a provided bobbin in which the thread is threaded. 2 Figure 12 is a schematic representation of a bobbin after successful threading of the thread. 3 Fig. 12 is a schematic representation of a bobbin after unsuccessful threading of the thread. 4 Fig. 12 is a schematic representation of a thread end falling onto the ribbon 17 when the bobbin is changed. So-called thread threading means that at a single-spindle unwinding station, a bobbin thread end 13 is blown from an air outlet through a pressure-lift nozzle 18, and then goes through the thread threading pipe 12 and a bobbin sensor 11 to a suction port of the small suction nozzle 7, and the bobbin thread end 13 is picked up by the small suction nozzle 7 and the bobbin thread end is picked up and sucked by the small suction nozzle 7. As in 1 shown, the bobbin 14 enters the single-spindle unwinding station with a normal thread end for threading, and meanwhile the large suction nozzle 6 locates a thread end 3 of the unit 1 and guides the thread end 3 to a ready position, as in FIG 1 shown.

As in 2 shown, the thread end 3 is inflated from a lift outlet by the air nozzle 18, and then is threaded by the air nozzle 18 through the thread threading tube 12 and the bobbin sensor 11 into the suction port of the small suction nozzle 7. The bobbin thread end 13 is grasped and sucked into the small suction nozzle 7 and introduced into the splicing device 5 to splice it with the thread end 3 sucked by the large suction nozzle 6 . The unit 1 is driven by a grooved drum 2 to rotate for winding. When the thread clearer 4 detects that the thread has a defect to be removed, the thread is cut; one end of the thread wound on the unit 1 is then relocated by the large suction nozzle 6 and the other end of the thread is picked up by a thread catcher 8 and cut again by the scissor unit 10. A tensioning device 9 is activated and an upper thread end of the bobbin thread end 13 is sucked away from the thread catcher 8 and the small suction nozzle 7 is displaced downward to pick up the end of the thread. The two thread ends are spliced again. As in 3 1, the bobbin thread end 13 falls because the small suction nozzle 7 does not suck the bobbin thread end 13 for some reason. As in 4 As shown, the spool 14 exits the single-spindle unwind station on the ribbon 17 and causes a tangle as the ribbon 17 moves.

Since the above problems affect the normal operation of the existing prior art automatic thread winding machine, maintenance work is greatly increased, generation of thread waste is significant, production cost is also increased, and production efficiency is lowered.

In view of the above problems, no reasonable and effective technical solution has been found in the prior art for a long time, and the applicant has also conducted research and development work on the above problems for several years. But through long-term research, it has been proved that an automatic mechanical transmission mechanism configured to pick up a new thread end at the single-spindle position relies on sensors and electric control, which is complex in structure and low in reliability, and besides can incur huge costs to upgrade the device.

Since each automatic yarn winding machine generally has 60 to 72 individual spindles, each individual spindle needs to be rebuilt, so the cumulative rebuilding cost is very high, and the manufacturers have to make significantly higher investments for such an upgrade, which hinders its use and application.

If a tub thread winding machine is provided where the small suction nozzle does not catch the bobbin thread end or other factors cause the thread end of the bobbin to fall, the falling bobbin thread end will automatically enter a bobbin center hole, so that a new thread end from the single-spindle unwinding station can be removed; or with an interruption in the normal operation of the tray caused by unwound threads, pulling an end of a new thread through the bobbin processing device is avoided; providing a winding machine that is simple in construction, inexpensive, and easy to upgrade is a technical problem that needs to be solved.

Summary of the Invention

In order to solve the problems and shortcomings of the prior art, the present invention provides a tub thread winding machine and a bobbin winding method, in which when the small suction nozzle does not catch the bobbin thread end or other factors cause the bobbin thread end to fall, the fallen falls lower end of line automatically into the center opening so that a new end of line can be drawn out of the single-spindle unwinding station; or in the event of an interruption in the normal operation of the installation caused by unwound threads, the bobbin processing device avoids drawing in an end of a new thread; a winding machine is provided which is simple in construction, inexpensive and easy to upgrade.

A thread winding process for a tub thread winding machine has the following steps:

• S1: A bobbin with a normal thread end enters the single-spindle unwind station; a thread end of the unit is located by the large suction nozzle and brought to a splicing position;
• S2: A bobbin thread end is blown by the air nozzle, then passed through the thread threading tube and a bobbin sensor to the air inlet of the small suction nozzle, and is caught and sucked by the small suction nozzle to insert it into the splicing device, and then connected to the thread end of the unit spliced, which was caught by the large suction nozzle;
• S3: The unit is driven by the grooved drum to rotate for winding;
• S4: During the winding process, if the thread cleaner detects during the winding process that the thread in the winding process has a defect that needs to be eliminated, the thread is cut and one end of the thread is wound onto the unit, and then located by the large suction nozzle; the other end being caught by the thread catcher and cut off by the scissor unit; meanwhile, the tensioning device is activated and an upper bobbin thread end is sucked away by the thread catcher, catching the small suction nozzle for picking up the remaining thread end of the bobbin and preparing it for splicing;
• S5: When the small suction nozzle fails to suck the bobbin thread end and further causes the bobbin thread end to fall down, the bobbin thread end passes through the upper bobbin hole and is sucked into a center hole of the bobbin due to the negative pressure at the upper end of the bobbin, with the thread end of the bobbin falling from the compressed air nozzle is blown to suck the bobbin thread end again when the bobbin is at the single-spindle unwinding station; wherein, when the suction of the thread end of the bobbin fails, the bobbin 14 is taken out from the single spindle and conveyed to the bobbin processing device to draw a bobbin thread by a drawing unit in the bobbin processing device; meanwhile, a bobbin is fed to the single-spindle unwind station to repeat the cycle.

An improvement of the above technical solution: In step S3, when the thread breaks spontaneously during the thread winding operation, and it is further determined whether the thread breakage occurs over the thread catcher, an end of the broken thread is wound onto the unit and then located by the large suction nozzle , the other end of the bobbin thread being caught by the thread catcher and being cut off by the scissor unit; whereby the tensioning device is activated and the upper end of the thread from the bobbin is sucked away from the thread catcher; the small suction nozzle is displaced downward to pick up and re-splice the remaining bobbin thread end; wherein, when the thread breakage occurs below the thread catcher, when the broken bobbin thread end falls down, it is sucked into the center hole by negative pressure; the compressed air nozzle is blown by the compressed air nozzle and then threaded through a yarn threading tube and the bobbin sensor to an air inlet of the small suction nozzle, and then is picked up and sucked by the small suction nozzle to feed it to the splicing device, and then is spliced to the yarn end of the unit, picked up by the large suction nozzle.

Another improvement of the above technical solution: In Step S3, during the winding process, when the thread cleaner detects a quality problem with the bobbin and the bobbin needs to be carried out, the scissor unit cuts the thread and the small suction nozzle cannot be shifted downward; with the thread end of the bobbin in the center hole of the thread bobbin falls for a bobbin exchange, the bobbin being conveyed to the bobbin processing device and being drawn out from the bobbin device.

A further improvement of the above technical solution: Every time the small suction nozzle is shifted downwards to pick up the thread end, the compressed air nozzle blows once, during the winding process a negative pressure is always maintained in the cavity of the negative pressure suction nozzle and the negative pressure value is in the range of 35 to 60 millibars.
