Technical field

The invention belongs to the field of ring spinning equipment, and in particular relates to a device for processing interrupted yarns during ring spinning spun yarn spinning.

Background technique

The ring spinning process generally includes the processes of blow room, carding, drawing, roving, spinning and winding. Ring spinning is the most commonly used spinning method on the market today. The fiber strips after drawing the sliver or roving are rotated and introduced through the ring traveler. The bobbin winding speed is faster than the traveler, and the cotton yarn is added It is twisted into spun yarn, which is widely used in various short fiber spinning projects, such as carding, combing and blending. The traveler is driven by the bobbin through the yarn strip to rotate around the steel ring. At the same time of twisting, the friction of the steel ring makes the rotation speed slightly smaller than that of the bobbin and is wound. The spinning speed is high, and the shape of ring-spun yarn is a conical spiral in which most of the fibers are transferred internally and externally, so that the fibers are wound and connected internally and externally in the yarn. The yarn has a tight structure and high strength, and is suitable for thread making, weaving and knitting, etc. Various products.

The existing patent CN201820567117.1 discloses a one-step twisting machine with a yarn breakage detection component and a cutting device. The one-step twister with a yarn breakage detection component and a cutting device is equipped with a yarn breakage detection component and/or a cutting device. , the yarn breakage detection component is used to detect whether the unmerged yarn is disconnected. If the unmerged yarn is disconnected, use the cutting device to cut all the feed yarns. The yarn breakage detection component is installed on the single yarn on the one-step twisting machine. Between the yarn guide part and the parallel yarn guide part, the cutting device is installed between the yarn breakage detection part and the parallel yarn guide part or between the parallel yarn guide part and the conveying roller. Among them, the yarn breakage detection component still uses motorized detection, and many spinning machines have begun to use laser to detect yarn breakage. For example, the patent CN201220194744.8 discloses a new laser-based yarn breakage detection component, and the accuracy and timeliness of laser detection Secondly, this device can only detect broken yarns and cut yarns, but it fails to make connections in time and requires workers to manually splice, which is not conducive to improving production efficiency.

The existing patent CN201820269261.7 is a spinning machine. The spinning machine is equipped with a spinning device that generates spun yarn. The yarn generated by the above-mentioned spinning device is output from the output roller, and the spun yarn is wound onto the package. device, as well as a splicing operating trolley that travels between the above-mentioned spinning devices, a yarn storage tension device between the above-mentioned spinning output roller and the above-mentioned winding device; a suction spinning device with negative pressure downstream of the above-mentioned yarn storage tension device Yarn end holding part, when the above-mentioned suction spinning yarn end holding part breaks yarn, the broken spinning yarn end can smoothly enter the negative pressure channel of the holding part and be at the prescribed position. Although this device can realize automatic splicing of broken yarns, the external splicing operation trolley adopts the steps of starting the broken yarn - moving into position - executing the splicing, which requires a certain amount of time during the entire task. Accurately reaching the yarn breaking station is poor in real-time, especially when yarn breaks occur at multiple stations, which is not conducive to ensuring the quality of spinning; furthermore, for the new spindle, the splicing operation Although the trolley can collect yarn ends, it cannot complete operations such as carrying yarn ends to complete perforation.

Six broken yarn detection parts are provided above the yarn guide 5. The six broken yarn detection parts A yarn doubling component 7 and a yarn storage component 9 are provided above, and an automatic connection component 8 is provided between the yarn breakage detection part 6 and the yarn guide 5 . Among them, the yarn storage component 9 is wound with multiple turns of yarn, and can continue to output a certain length of yarn when the yarn is broken, leaving a reasonable time gap for the yarn to be added. The yarn guide 5 is used to constrain the direction of yarn output from bottom to top and reduce the range of yarn swing. After the yarn is broken, the original yarn trajectory changes in the detection position of the 6 pieces of yarn breakage detection part, which adopts the laser detection principle and uses laser to instantly detect the problem of yarn breakage and feed it back to the control equipment of the production line. Issue stop/slow down commands to the corresponding work stations. On this basis, in order to improve the efficiency of breaking yarn and resuming yarn, the present invention is provided with a yarn protecting plate 10 on the side of the spindle.

The present invention arranges matching automatic connecting components 8 near the yarn, eliminating the need for back-and-forth scheduling like a splicing operating trolley, shortening the time gap for yarn replenishment, and helping to improve the quality of spinning yarn.

In this device, when the yarn is broken on a spindle that has not completely paid off, the yarn end falls on the outer peripheral surface of the swing grabbing mechanism 81, and the swing grabbing mechanism 81 directly grabs the yarn tail and yarn end in an orderly manner. Then the splicing is realized at the fast twisting mechanism 83. For a completely paid-off yarn spindle, the yarn tail still has a certain length on the yarn storage component 9, so its end can be automatically grabbed after the swing grabbing mechanism 81 performs the upswing action; for a newly replaced yarn spindle, the yarn end is attached On the spindle, the steel ring positioning mechanism 82 can position the steel ring 4 so that the steel ring 4 is almost flat after entering the predetermined position, and its inner ring faces the direction of the airway 101 in the working state. The air pressure collects the yarn end from the spindle. At the same time, the yarn spindle is released to a certain length under the rotation of the spindle positioning part 2. The yarn end collected by the air pressure passes through the steel ring 4 and then passes through the yarn guide 5, while the swing grabbing mechanism 81 performs the lowering action to grab the yarn end, and the movable suction device 814 drives the yarn end into the rapid twisting mechanism 83 to cooperate with the yarn tail and realize rapid twisting. The twisted yarn can automatically bounce away from the automatic connecting component under the tension of the production line. 8, thus allowing the production line to enter normal spinning operation.

Among them, the magnetic track of the linear motor is laid along the track on the swing arm, and the mover inside the linear motor can cooperate with the magnetic track to cause the movable attractor 814 to make corresponding displacements along the magnetic track. When the swing arm 812 rotates around the output center of the swing motor 811, it can pass through the range where yarn breakage occurs at the yarn end and yarn end. The air source provides negative pressure at the end of the hose, thereby effectively attracting the yarn end and yarn end. And fall on the groove surface of the U-shaped structure, and this U-shaped design also facilitates the twisted complete yarn to automatically bounce away from the swing grabbing mechanism 81.
