The present invention relates to a winding device for a circular knitting machine, and more particularly to a winding device for a circular knitting machine for adjusting a pressing force.

The circular knitting machine is a basic equipment for the textile industry. The knitting yarn of the same or different materials is woven into a loop fabric by using a plurality of knitting needles arranged on the dial and the cylinder, and the woven fabric is wound into a bundle. The flattener is a winder placed under the circular knitting machine.

A conventional type of winder, such as the US Pat. No. 7,441,723, includes a body, a drive shaft pivotally mounted on the side wall of the frame, and a body defined between a body and a stop disposed in parallel with each other. a displacement track, and a winding bar disposed in the displacement track and driven by the drive shaft. When the winder is actuated, the roll rod is driven by the drive shaft to perform a winding operation. At this time, the roll rod can be spliced through the cloth and the drive shaft, and is continuously increased as the roll movement continues. The thick cloth abuts against the drive shaft, causing the web to rise vertically in the displacement track. In order to keep the cloth flat during the winding process, the cloth rod is further provided with a cloth guiding rod group for pulling the cloth, and the cloth guiding rod group provides a force to the cloth when guiding the cloth to move. Cloth. In the process of initially winding the cloth, the cloth rod is generally rotated by the driving shaft, and when the weight of the cloth rod and the cloth is less than the tension of the cloth, the cloth rod is towed. Rotate in the opposite direction to the drive shaft. As the fabric retracted on the bobbin is continuously increased, the overall weight of the bobbin and the fabric is also increased, and the force of the transmission rod that is pressed underneath is also increasing.

The side box 11 includes a top side 111 adjacent the circular braiding machine and a bottom side 112 remote from the circular braiding machine. The transmission rod set 20 is disposed in the winding space 13 of the frame body 10, and is rotated by the driving mechanism 12 to guide the cloth 70 to move along a feeding path P. In order to provide the driving power of the present invention, the winding device further includes a drive base 40 located in the roll space 13. In the embodiment, a mounting plane S for the driving base 40 is formed between the bottom sides 112 of the side boxes 11. The driving base 40 includes a rotating base 41, a gearbox 42 disposed on the rotating base 41, at least one transmission shaft 43 extending from the transmission 42 and outputting a rotational power, and at least one connecting the transmission 42 The connecting rod 44 that rotates the side box 11 in synchronization with the side box 11 causes the gear box 42 to rotate. The drive shaft 43 passes through the bottom side 112 of the side box 11 and drives the drive mechanism 12 with a drive belt 121. Thus, the torque generated by the transmission 42 is output to the side box 11 through the transmission shaft 43, and the transmission shaft 43 is coupled to the transmission belt 121 to interlock the driving mechanism 12.

In the embodiment, the winding device further includes a cutting member 51 for cutting the cloth 70 into a continuous state from a continuous cylindrical shape. And a struts 52 that extend the fabric 70 that is cut through the arranging element 51. In order to enable the cloth 70 passing through the fabricating member 51 and the fabric frame 52 to enter the feeding path P in a flat and unfolded state, the winding device further includes a shaft disposed on the side box 11 of the frame body 10. The feed bar set 60 of the top side 111. The feed bar set 60 includes a spreader bar 61 that is rotated by the drive mechanism 12 to expand the fabric 70, and at least one scroll bar 62 that guides the fabric 70 to move toward the spreader bar 61. The spreader rod 61 includes a first threaded section 611 and a second threaded section 612 opposite to the first threaded section 611, and the folded wrinkles on the fabric 70 are pushed to the opposite sides. The surface of the cloth 70 is kept flat. The driving rod set 20 is entered by the rolling rod 62 and the cloth 70 of the spreading rod 61. The transmission rod group 20 is also interlocked by the driving mechanism 12 disposed in the side box 11, so that the cloth 70 is This feed path P is output to the rotation collecting mechanism 30. In the present invention, the rotary squeezing mechanism 30 includes two rotating arms 31 respectively pivoted on the side box 11, and one is located on the feeding path P and is rotated by the connecting rod group 20 to wind the cloth. 70 roll bar 32. The rotating arm 31 includes a rotating end 311 pivotally connected to the bottom side 112 of the side box 11 and a receiving end 312 connected to the winding rod 32 and higher than the rotating end 311. The rotating arm 31 has a rotation collecting stroke that is rotated upward by the bottom side 112 with the rotating end 311 as an axis with the increase of the amount of the cloth 70 on the winding bar 32. The cloth 70 retracted on the roll bar 32 abuts the drive bar set 20 to provide a press force component to the drive bar set 20. The frame body 10 includes at least one buffer hydraulic cylinder 14 disposed on the side box 11 and pivotally connected to the rotating arm 31, in order to smoothly move the rolling rod 32 when the rotating arm 31 performs the rotating and collecting stroke. .

As the volume of the cloth 70 increases on the roll bar 32, the circumferential length of the outermost periphery of the cloth 70 also increases. In order to enable the transmission rod set 20 to be closely attached to the fabric 70 and to rotate the fabric 70 retracted on the cloth rod 32 by friction, the transmission rod set 20 of the present invention includes a fixed shaft disposed thereon. a first guide bar 21 of the side box 11 , a second guide bar 22 movably disposed on the side box 11 and moving relative to the first guide bar 21 , and a set of the second guide bar 22 disposed on the second guide bar 22 The moving seat 23 that controls the movement of the second guide bar 22 is controlled.

As shown in FIG. 5, the moving base 23 includes a pivoting portion 231 pivoted to the side box 11, and a resilient member 232 that connects the moving base 23 to provide a restoring force. In this way, the second guide bar 22 can adjust the position relative to the first guide bar 21 according to the curvature of the outermost circle of the cloth 70 on the roll bar 32. The first guide bar 21 and the same The second guide bar 22 can maintain contact with the outermost fabric 70 on the roll bar 32 to drive the cloth 70 of the roll bar 32 to rotate.

Please refer to FIG. 3-1 and FIG. 3-2, which are schematic diagrams showing the steps of collecting the winding device of the circular knitting machine of the present invention. In the initial collection stage, as shown in FIG. 3-1, the fabric bar 32 retracts the fabric 70 from the output of the transmission rod set 20. As will be understood from the foregoing description, the bottom side 112 of the side box 11 is A mounting plane S is provided between the mounting base 40 and an angle θ formed between the mounting plane S and the extending axis A of the rotating arm 31 in the rotation receiving stroke. As the roll bar 32 retracts the amount of the cloth 70, as shown in FIG. 3-2, the roll bar 32 is centered, and the radius of the cloth 70 is also wound around the roll bar 32. Increased, because the outer edge of the fabric 70 retracted on the cloth web 32 abuts against the transmission rod set 20, the cloth rod 32 is interlocked and lifted upward, so that the rotating arm 31 is rotated by the rotating end 31 The rotation of the shaft is reversed by the bottom side 112. At this time, the angle θ formed between the installation plane S and the extension axis A of the rotary arm 31 in the rotation and collection stroke also becomes large.

The present invention utilizes the rotary arm 31 to perform the rotational take-up stroke to adjust the compressive component force Y applied to the drive rod set 20 by the fabric 70 wound on the spool 32. FIG. 6 is a schematic diagram showing the relationship between the components of the winding device in the state of being collected, and FIG. 7 is a schematic diagram of the components of the winding device in the state of being collected. The system includes the weight W of the cloth 70 and the web of the cloth 32, the gravity W providing the belt component Y and the supporting component force X for the transmission rod set 20 and the rotating arm 31, respectively. The following is a table showing the relationship between gravity W, angle θ, and force component Y under different fabric diameters R:

[0028] As can be seen from "Fig. 6" and "Fig. 7", the relationship between the compressive component force Y and the gravity W is: Y = W cos θ. It is known that the angle θ is defined as the angle at which the mounting plane S intersects with the extension axis A of the rotating arm 31 in the rotation and collection stroke. Therefore, when the angle θ increases with the amount of the cloth, FIG. 3-1 』 Increase to the state of Figure 3-2 (the angle θ is less than 90∘), the value of cos θ will gradually decrease (can also be shown in the table). Therefore, although the gravity W gradually increases during the process in which the cloth 70 is continuously retracted in the winding bar 32, the amount of cos θ is reduced, thereby adjusting the component force Y applied to the transmission bar group 20, so that In the process of winding up the cloth 70, the weight W provided to the transmission rod set 20 does not increase linearly.

When the fabric 70 retracted on the roll bar 32 reaches a predetermined amount, the rotating arm 31 performs a rotary lowering stroke away from the roll space 13 with the rotating end 311 as an axis, as shown in FIG. Show. The rotating arm 31 is pivotally disposed in the side box 11 through the buffer hydraulic cylinder 14. When the rotating arm 31 performs the rotating lowering stroke, the buffer hydraulic cylinder 14 can provide a buffering force opposite to the gravity W. The cloth 70 that is wound around the web 32 can smoothly pass the cloth. In the present invention, the frame 10 includes a lower shelf 15 for receiving the wrapped fabric 70 in the rotating lower cloth stroke. In addition, in order to prevent the amount of the fabric 70 retracted on the cloth web 32 from being excessive, the rotating arm 31 directly enters the rotation and lowering stroke by the rotating and unloading stroke, and the rotating arm 31 includes a stopping portion 313. The side box 11 includes a restricting portion 114 that abuts against the stopping portion 313 to prohibit the rotating arm 31 from performing the rotating lowering stroke. The restricting portion 114 is pivotally disposed on the side box 11 and includes a closed state against the stopping portion 313 (as shown in FIG. 1 ), and an opening that allows the stopping portion 313 to leave the winding space 13 . Status (as shown in Figure 5).

The rolling device of the circular knitting machine of the present invention is specially provided with two rotating arms pivoted on the side box, the rotating arm includes a rotating end pivotally connected to the bottom side of the side box and a connecting roller rod Higher than the receiving end of the rotating end. As the fabric retracted on the web is gradually increased, the bobbin rod is also rotated for a rotation take-up stroke to adjust the force distribution to the transmission rod set. Therefore, the winding device of the circular knitting machine of the present invention overcomes the conventional winder, and the force distribution of the cloth bar and the total gravity of the cloth to the transmission rod group is continuously increased during the process of winding the cloth. The problem is to effectively maintain the quality of the fabric that is initially retracted and the fabric that is later retracted, including the density of the woven thread and the thickness of the fabric, which greatly reduces the part of the fabric that must be discarded because it does not meet the quality requirements, and improves the use of the entire fabric. rate.
