Technical Field
The invention relates to the technical field of spinning mechanical equipment, in particular to a yarn spinning mechanism.
Background
A spinning machine is known which twists a fiber to produce a spun yarn and winds the spun yarn around a package, and a spinning machine described in the literature produces a rotating air flow in a spinning chamber by ejecting compressed air from an air-jet spinning nozzle, and twists a fiber bundle with the rotating air flow to produce a yarn. Conventionally, a spinning unit that produces a spun yarn by drafting a fiber bundle and twisting the drafted fiber bundle is known, and the spinning unit is provided with a yarn defect detecting section that can detect a defect portion of the spun yarn and a winding section that winds the spun yarn to form a package.
Conventionally, a spinning machine including a plurality of spinning units is known, in which a work carriage that travels to a spinning unit when a continuous state of a spun yarn is cut in one spinning unit and performs a splicing operation is provided, and the splicing operation carriage is provided with a braking section capable of braking rotation of a package, a guide section that captures and guides the spun yarn, and a joint section that joins yarn ends of the spun yarn to each other.
The spinning unit cuts the spun yarn and other yarns when the yarn defect detecting section detects a defective portion of the spun yarn, and interrupts the operation of the package. When the splicing operation carriage reaches the spinning unit, the braking portion is brought into contact with the package to stop the rotation of the package. Then, the guide portion for the splicing operation carriage moves to the package side, and then the package is rotated (reversed) in the unwinding direction by the reverse roller so that the guide portion (large suction nozzle) can catch the package spinning head, and the guide portion (large suction nozzle) can catch the spinning head smoothly, and the yarn defect is removed and guided to a predetermined position, and the yarn ends of the spun yarn are joined to each other by the splicing operation carriage joint portion after the defect portion is removed. After the series of steps, the spinning unit resumes the package formation.
When the moment of inertia of the package is large, such as when the outer diameter of the package increases due to a large spun yarn being wound, even if the braking section is brought into contact with the package for a predetermined time, the rotation of the package may not be stopped. The friction between the braking section and the package sometimes makes it difficult for the guide section (large suction nozzle) to catch the spinning head. When the rotation of the package cannot be stopped, the package cannot be reversed even by using the reverse roller, and the guide portion (large suction nozzle) cannot catch the yarn end wound around the package. The quality of the spun yarn wound into the package may be deteriorated by the reverse roller.
In order to solve the problem, the patent application No. 201210323456.2 provides a spinning machine in which the rotation of the package can be stably stopped by adjusting the contact time of the package with the braking portion. The reverse roller is smoothly reversed, and the guide part (large suction nozzle) is smoothly caught at the spinning head for a predetermined time. The above-described solution still does not completely solve all the problems, and there are also problems that the brake section comes into contact with the package and the reverse roller comes into contact with the package and the friction occurs, that is, the guide section (large suction nozzle) may not catch the yarn end wound on the package, that even if the yarn end wound on the package is caught, there is a time when the yarn end has an unwinding yarn defect, and that the long-term efficiency of the operation time of the splicing work carriage is low.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a yarn spinning mechanism, which reduces the operation flow, reduces the splicing operation time and improves the working efficiency.
In order to achieve the purpose, the invention provides the following technical scheme: a yarn spinning mechanism comprises a drafting device, a spinning part, an output device, a yarn storage device and a winding part which are sequentially arranged from top to bottom, wherein the yarn storage device comprises a yarn storage roller and a yarn guide flyer, a retractable and movable flyer stopper is arranged on one side of the yarn guide flyer, and the flyer stopper controls the yarn storage device to unwind yarns when the yarns are broken.
The spinning machine has a plurality of spinning mechanisms arranged in an array, and a splicing operation trolley, and a fiber bundle passing through a drafting device passes through a spinning section to generate a spun yarn, and is conveyed by a delivery device, and then conveyed by a yarn storage device to be wound by a bottom winding section to form a package. In the spinning process, when the yarn with defects is cut off or the spun yarn is cut off under other conditions, the winding part of the spinning mechanism stops rotating, the yarn storage roller drives the yarn guide flyer to continue rotating, when the yarn storage device detects that no yarn exists, the flyer stopper is started to be contacted with the yarn guide flyer, and the yarn guide flyer and the yarn storage roller rotate together under the control of magnetic force fit, so that when the force between the flyer stopper and the yarn guide flyer is larger than the magnetic force between the flyer stopper and the yarn storage roller, the yarn guide flyer does not rotate together with the yarn storage roller, the remaining yarn is unwound through the flyer stopper, and meanwhile, the winding part reversely rotates to remove the yarn defects. The splicing operation trolley moves to the spinning mechanism to directly perform splicing operation to complete the yarn breaking and splicing operation. The spinning mechanism is simple in design, reduces the operation flow, reduces the splicing operation time and improves the working efficiency.
Further, the winding part is connected with a braking part for driving the winding part to rotate independently, and the braking part of the spinning mechanism can independently drive the winding part to stop or rotate. In the spinning process, when the yarn with defects is cut off or the spun yarn is cut off under other conditions, the braking part of the spinning mechanism independently drives the winding part to stop rotating, and after the upstream yarn end is unwound, the braking part drives the winding part to reversely rotate to finish yarn defect unwinding, so that the splicing operation trolley finishes the work of yarn breakage and yarn splicing. The intermittent braking mode of stopping the rotation of the spinning mechanism package is eliminated, the reverse rotating roller of the package is reversely rotated, the time for catching the spinning head guiding part and withdrawing yarn faults is shortened, the operation flow is reduced, the splicing operation time is shortened, and the working efficiency is improved.
Further, the flyer stopper comprises a fixed plate, an adjusting cylinder is mounted on the fixed plate, and the adjusting cylinder is in contact with the yarn guide flyer after stretching. The fixed plate is fixed on one side of the yarn guiding flyer, the adjusting cylinder is arranged on the fixed plate, after the spinning is cut off, the starting cylinder is contacted with the yarn guiding flyer, the yarn guiding flyer is pushed by the cylinder, when the pushing force of the air cylinder exceeds the magnetic force between the yarn guiding flyer and the yarn storage roller, the yarn guiding flyer does not rotate with the yarn storage roller, and the remained yarn is unwound through the flyer stopper.
A plurality of mounting holes are formed in the fixing plate, and the mounting holes are waist-shaped holes along the telescopic direction of the adjusting cylinder. The position of the fixing plate can be adjusted back and forth by the design of the waist-shaped hole to ensure contact with the yarn guiding flyer.
Further, the winding part includes a bobbin for winding the yarn, a surface of the bobbin is in contact with the braking part, and an angle adjusting device is connected to the bobbin. When the bobbin increases the diameter of the yarn layer of the package due to the yarn being wound, the surface of the package can be continuously brought into proper contact with the drum by adjusting the contact of the bobbin with the braking portion by the angle adjusting device.
Further, the angle adjusting device comprises a rocker arm frame connected with two ends of the bobbin, a rotating block is hinged to the bottom of the rocker arm frame, and the rotating block is connected with a driving mechanism. The driving mechanism operates to push the rotating block upwards so that the rocker arm frame drives the roller to be far away.
Further, the driving mechanism is a driving air cylinder, and the rotating block is provided with an ejector rod matched with a piston rod of the driving air cylinder. The driving cylinder runs and extends upwards to prop against the top rod above, so that the rotating block rotates.
Further, the braking portion includes a winding drum in contact with a surface of the winding portion, and the winding drum is connected with a motor driving the winding drum to rotate. The winding drum includes a central stator portion and an outer rotor portion at the periphery of the stator, which are independently driven for rotation by a motor.
Furthermore, an electronic yarn cleaner and a tension sensor are arranged between the output device and the yarn storage device, and a yarn sensor, a holding part with negative pressure and a yarn breakage sensor are sequentially arranged between the yarn storage device and the winding part. The spun yarn produced in the spinning section passes through an electronic clearer and a tension sensor before being wound by the yarn accumulating device, the electronic clearer monitors the thickness and the like of the running spun yarn, the tension sensor monitors the tension value of the running spun yarn, and the spun yarn is cut when a defect is detected during spinning and the tension is lower than a set value. After the yarn is cut, the yarn end is sucked by the holding part with negative pressure, and the yarn cutting sensor sends a signal to make the splicing operation trolley travel to the position to splice.
The yarn winding device further includes a traverse device for controlling the traverse winding of the yarn into a package, and the traverse device includes a traverse guide capable of guiding the spun yarn, and traverses and winds the spun yarn onto a bobbin by driving the traverse guide to reciprocate to form the package.
The spinning machine further comprises a control part, and the control part controls the automatic operation of the whole spinning mechanism. The control part can receive various signals and control the spinning mechanism to automatically run, and the whole working operation can be completed without manual intervention.
As described above, in the yarn spinning mechanism according to the present invention, at least one flyer stopper is provided in the yarn head holding section and the independently driven winding section disposed on the downstream side of the yarn guide flyer. The spinning mechanism cuts the spun yarn when detecting a defective portion of the spun yarn or cuts the spun yarn in some other cases. The winding part is independently driven to stop rotating, and the yarn storage roller drives the yarn guide flyer to continue rotating. When the yarn storage roller sensor detects that there is no yarn, the flyer stopper is started to contact the yarn guide flyer, the yarn guide flyer does not rotate together with the yarn storage roller, and the remaining yarn is unwound by the flyer stopper into the yarn suction thread end holding portion having a negative pressure. Meanwhile, the winding part is independently driven to reversely rotate and retreat yarn , yarn defects enter a yarn negative pressure channel of the holding part and are held at a specified position, and the splicing operation trolley directly performs splicing operation after moving to the spinning unit for positioning.
The invention has simple integral structure design, removes an intermittent braking mode for stopping the rotation of the package of the spinning mechanism, reverses the reverse roller of the package, captures the guide part of the spinning head and finishes the time of yarn faults, thereby reducing the operation flow, reducing the splicing operation time and improving the working efficiency. The splicing operation trolley has no relative friction of the braking part to the winding part, no relative friction of the reverse roller to the winding part and no damage to the spun yarn on the winding part, thereby improving the quality of the spun yarn and ensuring the possibility that the guide part catches the spun yarn head. The manufacturing efficiency of the spun yarn in each spinning mechanism can be improved, and the production efficiency of the package in the spinning machine can be improved.
