Description

Yarn winding device

The present invention relates to a thread winding device for winding the thread uniformly with a constant tension on the bobbin.

As shown in FIG. 1, a conventional thread winding apparatus is provided with a spindle for rotating a bobbin 1 wound around a thread on an upper side of a support plate 10, and includes a support pillar 11 at an upper center thereof. The member 12 is installed in the seesaw movement and seal guiders (not shown) are wound around the bobbin 1 on one side of the rotating member 12.

A drive body 20 having a hexahedron shape having an open upper portion is installed at a lower portion of the support plate 10, and a drive cam 24 having a drive motor 21 and a gradient surface of upper and lower dead centers is provided on the drive body 20. ) And a drive arm 33 which is pivoted up and down by the gradient surface of the drive cam 24.

The drive cam 24 has a vertical camshaft 22 having a worm wheel 25 at the bottom thereof, and at one side thereof, a drive shaft 23 having a worm 26 engaged with the worm wheel 25 is constructed. The pulley 27 is installed at one end of the drive shaft 23 and a belt wound thereon to receive power from the drive motor 21 to rotate.

In addition, one end of the drive arm 33 is coupled to the shaft coupled to one side of the drive body 20 is installed so as to rotate the shaft to a peak, the other end is coupled to the rotation member 12 by a turnbuckle 31 It is connected to the link 32 and interlocked with the rotating member 12, the hexagonal lead slider 34 is pivotally coupled to one side sliding on the gradient surface of the drive cam 24, the turnbuckle 31 is connected At the end of the driving arm 33, the restoring spring for restoring downwards or a weight (not shown) is installed.

In addition, the shaft portion, which is the apex of the rotational angle of the driving arm 33, is slowly moved up and down at a predetermined period by a separate cam driving device not shown in the drawing, so that the rotation member 12 rotates according to the change in the position of the peak of the driving arm 33. By varying the position of the section, the position where the thread is wound along the outer circumferential surface of the bobbin 1 is changed up and down.

The conventional thread winding device configured as described above has a drive pulley 27 when the drive motor 21 of the drive body 20 operates in a state in which the bobbin 1 is rotated at a constant speed by a spindle installed on the support plate 10. The cam cam 22 is rotated while the cam cam 22 is decelerated by the power transmission through the worm 26 and the worm wheel 25.

By the rotation of the drive cam 24, the lead slider 34, which is in contact with the gradient surface, moves up and down periodically along the gradient surface, and one end of the driving arm 33 having the lead slider 34 also has its pivotal axis at its rear end as its peak. Rotate up and down.

By this operation, the pivot member 12 connected to the driving arm 33 and the turnbuckle 31 is repeatedly moved around the axis of the support pillar 11, and the seal guiders (not shown) installed at the end thereof are moved up and down. The thread is guided up and down and wound around the bobbin (1) of the spindle.

At this time, the thread wound on the bobbin 1 is wound in a predetermined pattern. First, as shown in FIG. 2A, the supply of the thread moves the lead slider 34 from the bottom dead center of the driving cam 24 to the top dead center. In other words, while the driving arm 33 moves upward, the lower edge A of the outer circumferential surface of the bobbin 1 is wound to a point B, which is a fixed point of the middle upper end, and the lead slider 34 is rotated at the top dead center of the drive cam 24. During the movement to the bottom dead center, that is, while the driving arm 33 moves downward, it is wound in the opposite direction from the point B to the point A on the outer circumferential surface of the bobbin 1, and the supply of such a thread in accordance with rotation of the drive cam 24 The reciprocating stroke is repeated.

On the other hand, the driving arm 33 of the seesaw movement has its rear end gradually lowered with a certain time difference, and the leading end of the driving arm 33 is relatively raised, so that the thread is wound around the bobbin 1 at point A. The width of the point is the same, but over time, the thread winding from the lower point A to the B point is gradually moved upward, and finally the point is wound from the point D to the point C.

That is, as shown in (b) of FIG. 2, the diameter of the bobbin 1 is largely wound from the point D to the point B, which is the middle part of which the overlap is many times, and the diameter of the bobbin 1 is smaller at the upper end and the lower end of the bobbin 1. Cold.

In the conventional realization method, the more the yarn is wound on the outer circumferential surface of the bobbin (1), the lower the rotational speed of the spindle per hour due to its own weight. The diameter of the bobbin (1) from the point D to the point B is a large diameter When the thread is wound, the moving speed of the thread is supplied fast, so the thread is wound tightly at the larger diameter, but the lower part and the upper part of the bobbin 1, in which the thread is wound around the larger diameter of the bobbin 1, becomes smaller. When the thread is supplied to the outer circumferential surface, the moving speed of the thread is supplied quickly, but the rotational speed of the spindle is slowed down by its own weight, causing the thread to be loosely wound on the bobbin 1.

As described above, the yarns wound loosely on the bobbin 1 are not only entangled with each other, but also wound around the rollers, so that the thread is frequently trimmed.

On the other hand, when the thread is wound in the pattern as described above, the lead slider 34 has a corner in the groove formed in the gradient surface at the bottom dead center of the driving cam 24 slope surface, one of the six surfaces in order to drive cam ( As shown in FIG. 3, the lead slider 34 has a center of rotation formed at an eccentric position of the regular hexagonal cross section so that the thread is wound by the length difference from the center of rotation to each of the six contact surfaces. The starting point and the return point are different for each side, so you don't have to wind them up again.

However, since the conventional lead slider 34 circulates six processes and circulates the same process again after the seventh time, it is still dense because the shape is repeatedly wound with the same properties in view of the number of times actually wound on the bobbin. There was an issue that was not rolled up firmly.

The present invention to solve the above conventional problems,

By adjusting the rotation angle of the rotating member to the winding width adjusting means and the driving body moving in the same direction, the pattern and the section change of the thread wound on the bobbin are made more delicate and stable, and the rotation accordingly The object of this invention is to provide a thread winding device which allows the rotational movement angle of the member to be reduced very gently with a certain time difference, and to control the rotational speed in the controller so that the tension change of the thread wound on the outer peripheral surface of the bobbin is minimized. .

Another object of the present invention is to form the structure of the lead slider to move along the gradient surface of the drive cam in the form of a hexagonal or odd angle and the center of rotation of the lead slider eccentric to the lead slider surface is rotated Even when it comes, the position of the thread winding on the bobbin is different and the lead slider is wound on the bobbin by the distance difference between each contact surface of the lead slider and the center of rotation when the rotating member rotates continuously at the top dead center and the bottom dead center. An object of the present invention is to provide a thread winding device that prevents a thread from being wound repeatedly.

The present invention for achieving the above object, a rotating member having a support plate, at least one spindle for mounting the bobbin on the upper side of the support plate, and a seal guider for guiding the thread to the bobbin, coupled with the rotating member And is installed to be rotated together and is wound between the winding width adjusting means for adjusting the winding width of the thread wound on the bobbin, the first driving means for driving the winding width adjusting means, and the support plate to repeatedly rotate the rotating member.

While moving to the top dead center, the bobbin is wound from the point A of the lower end of the outer circumferential surface of the bobbin 1 to the point A 'of the top, and the lead slider 36 moves from the top dead center of the drive cam 44 to the bottom dead center. 1) Wind it in the opposite direction from point A 'to point A on the outer circumferential surface, but gradually The winding is reduced in stroke width, and finally, the winding is wound from the F point, which is the middle part of the bobbin 1 to the F 'point, to be wound as shown in FIG.

This thread winding method is wound around the bobbin (1) outer circumferential surface is wound around a larger diameter portion, so the actual thread is wound around the bobbin (1) outer peripheral surface even if the rotational speed of the spindle is slowed down by its own weight Relatively fast moving yarns are always kept taut, which causes them to wind tightly.

On the other hand, the hexagonal bolt type lead slider 36 has a regular hexagonal cross section having seven surfaces which are in contact with the driving cam 44 in order, and its rotation center is lowered from the center point by a predetermined width as shown in FIG. 10. Are moved to one side of the centerline, so that the lengths of each of the seven contact surfaces are different from each other at the center of rotation, but gradually increase from the first side to the fourth side, and then gradually decrease from the fifth side to the seventh side. do.

Therefore, as described above, the thread winding method of the present invention basically reduces the stroke width of the thread wound up to the upper end and the lower end of the bobbin 1 and moves to the middle part, but each of the seven contact surfaces of the lead slider 36 is moved. As the length of the rotation center and the length of the drive cam 44 to the gradient surface changes, the position where the thread is wound on the bobbin 1 is changed slightly.

That is, when the first surface of the seven surfaces is in contact with the gradient surface of the drive cam 44, it is wound in the AA 'section, when the second surface is in contact with the BB' section is wound, and when the third surface is in contact with the CC When the section is wound and the fourth side is in contact, the section is wound into the DD section, and when the fifth side is in contact, the section is wound slightly lower than the section DD ', and gradually downwards until the sixth to seventh surfaces are in contact. When the seventh surface is in contact with, the first surface is wound slightly higher than when the first surface is in contact.

Therefore, when one cycle is circulated and the first surface is contacted again, the same effect as that of the second surface is already obtained, so that the position where the thread is wound on the bobbin (1) has different properties without overlapping. Make sure that it is wound tightly.

The lead slider 36 may be formed in a cross section having odd surfaces such as five angles and nine angles in addition to seven angles.

Therefore, the rotational movement angle of this high stability member is slowly decreased with a certain time difference to achieve a stable state of supplying and winding the thread, and the top dead center of the thread where the lead slider of the hexagonal bolt is wound on the bobbin. After the bottom dead center position is deformed continuously to prevent the double winding phenomenon, the thread wound on the bobbin is always wound to a constant tension to effectively prevent the thread from being broken, and after the bobbin is loosely wound, the shape of the bobbin is completed. The problem that the thread was not loosened during use is effectively solved.
