Description

A winding system for air-covered yarn machine

technical field

The invention relates to an air-covered yarn machine, in particular to a winding system used on the air-covered yarn machine.

Background technique

The air-covered yarn machine is a kind of yarn processing machine. It passes the spandex delivered from the spandex feeding device with a certain draft ratio and the untwisted filament (nylon/polyester DTY) through the air covering device in compressed air. Under the action of network wrapping, two or more fibers with different physical properties are intertwined to form a yarn—air-covered yarn. An important process in air wrapping is package. The formation of the package is composed of two parts: the winding mechanism and the traversing wire arrangement mechanism. Through the joint action of the two, the yarn can be laid on the surface of the reel according to certain rules and wound into a package with a certain shape and capacity. Cylindrical rolls.

The winding mechanisms currently on the market can be mainly divided into two types: friction type and spindle type. The friction winding mechanism actively drives the friction roller, and the reel is driven by the contact friction of the friction roller, which is generally used in low-speed situations. This kind of friction winding mechanism is prone to slipping, heating, wrinkling, edge swelling, inner layer deformation of the package, and convex edges, which affect the molecular orientation of the fiber and the physical properties along the fiber length; the spindle type high-speed winding mechanism is driven by a motor The spindle is directly driven, and the motor speed gradually slows down with the increase of the package diameter, and the spindle speed is feedback-controlled according to the change of the contact roller speed. At present, the most commonly used method is to feedback the speed of the spindle shaft according to the change of the speed of the contact roller, which overcomes the shortcomings of the friction type, but because the contact roller is driven by the friction of the spindle shaft, the speed control accuracy of the spindle shaft is not very high.

At this time, the encoder has an initial value. Supported on the contact roller, the turret rotates a certain angle and the angle is measured by the encoder, that is, ∠O ₃ O ₁ O ₂ = θ ₀ , and the controller calculates the diameter of the reel according to the angle d ₀ , when the yarn is not wound, the reel is tangent to the contact roller; when the yarn is wound, the increase of the thickness of the yarn wound on the reel is equivalent to the increase of the outer diameter of the reel, that is, the contact roller and the contact roller The center distance of the reel increases, and the contact roller lifts the reel by the yarn to make the turntable rotate at a certain angle, and the encoder measures the rotation angle of the turntable again, that is, ∠O ₄ O ₁ O ₂ = θ to calculate the roll The thickness h of the yarn wound on the drum.

For the limit switch and zero switch, the shuttle swings back and forth from side to side, and before the cable is started each time, the shuttle will return to the zero point first, and then start to swing back and forth. The limit switch is to control the range of motion of the shuttle. If the swing of the shuttle exceeds the range of the limit switch, the controller sends an order to stop the winding system.

As shown in Figures 12 to 14, a method for measuring the diameter of the reel of an air-covered yarn machine and the thickness of the yarn on the reel, which is applied to the present invention, includes the following steps:

The point _O2 is used to install the reel 3, and the connection line between the first hinge point _O1 and the second hinge point _O2 is collinear with a straight line M. It is horizontal before loading the reel. When the turret rotates around the first hinge point _O1 , the first hinge point _O1 always falls on the straight line M; the second hinge point _O2 is the left fixing part 15 and the right fixing part 17 place.

Step 4: According to the measured angle θ ₀ and distance R, calculate the diameter d ₀ of the reel = 2Rsinθ ₀ ;

Step 5: After the yarn is wound on the reel, a coil 31 of yarn with a certain thickness is formed, so that the coil 31 is tangent to the straight line M and the coil 31 is tangent to the straight line M at a second tangent point O ₄ , specifically, Because the reel 3 is supported on the straight line M or the reel 3 is supported on the horizontal plane passing the straight line M or the reel is supported on an object, when the reel winds the yarn, the straight line M or the straight line M The horizontal plane or an object supporting the reel acts on the coil and lifts up the coil (including the reel) to make the turntable rotate. During the rotation of the turntable, the first hinge point _O1 always falls on the straight line M. At this time The connecting line between the first hinge point O ₁ and the second hinge point O ₂ deviates from the straight line M, and the rotation angle measuring device measures the rotation angle of the turret around the first hinge point as θ, that is, ∠O ₄ O ₁ O ₂ =θ;

Step 6: According to the measured angle θ, calculate the diameter of the coil d=2Rsinθ;

Step 7: Based on the calculated diameter d ₀ of the drum and the diameter d of the coil, calculate the thickness of the yarn wound on the drum $h=\frac{d-d_0}{2}.$

When the reel is mounted on the second hinge point, the turntable will be lifted to a certain angle, and measured by the angle The device can measure the size of the angle to calculate the diameter of the reel. When winding the yarn, the diameter of the coil increases continuously with the winding of the yarn, and the coil lifts the turntable again so that the turnframe can Rotation is caused by the change of the diameter, and the angle of the turret deflection is monitored in real time by the angle measuring device to calculate the diameter of the coil, and the thickness of the yarn wound on the drum is calculated according to the diameter of the drum, according to the calculated coil The diameter of the drum and/or the thickness of the yarn wound on the drum is used to control the speed of the winding motor that drives the drum to rotate.
