Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waxing device for an open-end spinning frame.

In general, yarn spun using an open-end spinning machine and wound onto a bobbin is finally passed through a loom, knitting machine, etc. to form woven or knitted fabrics.

However, especially during knitting, large frictional resistance is applied to the yarn when it comes into contact with knitting needles or guides that operate at high speeds, causing yarn breakage and fuzzing, which hinders the operation of the knitting machine. This also caused knitting injuries.

In order to eliminate such problems in the process after spinning, when the yarn spun from the spinning chamber in an open-end spinning machine is wound onto a bobbin, wax is applied to the yarn to make it smooth. There has been a desire for a waxing device that provides the following.

In order to meet such demands, for example, as shown in FIG.
A support piece 34 is formed protruding from the side of the support piece 34.
A shaft pin 35 is provided protruding from the side of the shaft pin 35, and a wax 31 is rotatably attached to the shaft pin 35 so that one surface thereof is on a tangent connecting the outer circumferences of the top roller 32 and the split drum 36. A waxing device has been proposed in the past in which wax is applied to the thread 37 while applying tension to the thread 37 running between the top roller 32 and the split drum 36 by the weight of the thread 31.

However, in the conventional waxing device described above, as shown in FIG. There was a defect in that the yarn 37 could not be held in position and the yarn 37 could not be waxed uniformly.

The present invention has been made in order to eliminate the above-mentioned defects in the conventional waxing device, and its purpose is to move the wax supporting member in correspondence with the yarn traveling position between the yarn pulling-out mechanism and the yarn winding mechanism. The support member is mounted so as to be tiltable in the front-rear direction, that is, in the direction toward and away from the machine frame, and the support member is provided with the wax at an optimal waxing position when it comes into contact with a fixed shaft for supporting the top roller that constitutes the thread drawing mechanism. An object of the present invention is to provide a waxing device for an open-end spinning frame, which can always maintain wax at an optimal waxing position and uniformly wax the yarn by attaching a regulating piece that can hold the wax at the optimum waxing position.

The present invention is a creation of a technical idea that reasonably achieves the above object.

Hereinafter, one embodiment of an open-end spinning machine embodying the present invention will be explained with reference to FIGS. A spinning chamber 41 for spinning a sliver, a yarn pull-out mechanism for pulling out the yarn 42 spun upward from the spinning chamber 41, and a yarn 42 pulled out by the yarn pull-out mechanism to be wound while traversing. The yarn winding mechanism includes a yarn winding mechanism for taking up the yarn, and a waxing device disposed at a yarn traveling position between the yarn pulling-out mechanism and the yarn winding mechanism.

Therefore, before explaining the structure of the waxing device which is the main part of the present invention, the structure of the thread pull-out mechanism and the thread winding mechanism will be explained with reference to FIGS. 2 and 3.
A pull-out roller 43 common to all spindles for pulling out the spindle from the spinning chamber 41 is rotatably supported by the machine frame 40, and is actively rotated in the direction of the arrow in FIG. 2 by a suitable drive mechanism (not shown).

A fixed shaft 4 is fixed to the machine frame 40 above the pull-out roller 43 and parallel to the pull-out roller 43.
4, a large number of support arms 45 are rotatably attached to each weight, and the pull-out roller 43 is attached to the tip of each support arm 45.
Top rollers 46 that are in sliding contact with the circumferential surfaces of the rollers are rotatably supported.

In addition, a part of one side peripheral edge of these top rollers 46 has
As shown in FIG.
A thread hooking portion 47 for guiding the thread is formed between the wire and the wire.

A traverse rod 48 common to all spindles is supported movably in the axial direction on the machine frame 40 so as to be parallel to the pull-out roller 43 at the front lower part of the joint between the pull-out roller 43 and the top roller 46. A large number of yarn guide grooves 49 are formed on the outer periphery for each spindle to lock and traverse the yarn 42.

Therefore, when the yarn 42 spun from the spinning chamber 41 is hooked on the yarn hooking portion 47 of the top roller 46 and guided between the top roller 46 and the pull-out roller 43, the yarn 42 is pulled into the traverse slot. While being traversed by the thread guide grooves 49 of the thread guide 48, the threads are drawn upward by the top roller 46 and the drawing roller 43.

Above the thread drawing mechanism, a drawing roller 43
A rotating shaft 50 common to all the spindles is rotatably supported by the machine frame 40 so as to be parallel to the rotating shaft 50, and is actively rotated in the direction of the arrow in FIG. 2 by an appropriate drive mechanism (not shown).

Further, a large number of split drums 51 having traverse grooves 52 are fixed to the outer periphery of the rotating shaft 50 for each weight,
As the rotating shaft 50 rotates, the thread 42 drawn upward from the thread drawing mechanism is traversed.

A bobbin holder 54 for each spindle, which corresponds to each of the split drums 51 and is rotatably attached to the upper end of the machine frame 40 via a support frame 53, has a bobbin holder 54 that is in sliding contact with the circumferential surface of the split drum 51. Bobbins 55, which are rotated in the direction of the arrow in FIG. 2, are each detachably attached.

Therefore, the thread 42 drawn upward by the thread drawing mechanism is guided to the split drum 51 while traveling in a certain manner between the thread drawing mechanism and the thread winding mechanism, and the thread 42 is guided to the split drum 51 by the rotation of the split drum 51. Accordingly, all the weights are wound onto the bobbin 55 at the same time without being traversed according to the traverse groove 52.

The yarn 42 spun from the spinning chamber 41 in this manner is pulled upward by the yarn drawing mechanism, and then traversed within the range of the yarn traverse plane between the top roller 46 and the sprint drum 51. The thread 42 is wound by the thread winding mechanism, and a waxing device is provided for each spindle at the thread traveling position between the thread pulling-out mechanism and the thread winding mechanism, and the thread 42 is wound by the thread winding mechanism. The yarn 42 has previously been coated with wax.

Next, the embodiment of this waxing device for one weight will be explained with reference to FIGS. is attached, and the attachment angle position of the support member 60 can be arbitrarily adjusted by loosening and tightening the attachment screw 61.

Further, as shown in FIG. 5, the outer surface of the thread guide portion 60a that protrudes to one side from the upper end of the support member 60 is formed in an oblique shape that becomes lower toward the tip, and the inner surface is located at approximately the center position. A support shaft 62 is protruded so as to be orthogonal to the traverse plane of the yarn 42 and to be inclined downwardly thereto.

The approximately disk-shaped guide plate 63, which is attached to the support shaft 62 so as to be rotatable and movable in the axial direction, has a yarn guide surface 53a on its inner surface, and as shown in FIG. The outer peripheral edge is formed to a size that does not protrude from the tip of the thread guide section 60a.

Also, like the guide plate 63, it is rotatable on the support shaft 62,
Furthermore, the approximately disk-shaped wax 64 made of paraffin or the like is attached so as to be movable in the axial direction, and the wax 64 is attached to the guide plate 6
A yarn contact surface 6 is provided on the side opposite to and in contact with the yarn guide surface 63a of No. 3.
4a, and as shown in FIG. 5, its outer peripheral edge is formed in such a size that it slightly protrudes from the tip of the thread guide portion 60a.

Therefore, when the thread 42 is hooked on the thread hooking portion 47 of the top roller 46 and held between the top roller 46 and the pull-out roller 43, the thread 42 is When the thread 42 is locked at an appropriate position on the outer surface of the thread guide section 60a shown in the figure, as the thread 42 traverses, it is guided along the outer surface of the thread guide section 60a toward its tip as shown in FIG. It comes off the tip of the thread guide portion 60a, is locked to the thread contact surface 64a of the wax 64, and is then guided between the thread contact surface 64a of the wax 64 and the thread guide surface 63a of the guide plate 63 for waxing. becomes possible.

The substantially disk-shaped weight 65, which is rotatably and movably attached to the support shaft 62 and movable in the axial direction, is tilted downward toward the traverse plane of the yarn 42, so that The weight acts to press the yarn contact surface 64a of the wax 64 against the yarn guide surface 63a of the guide plate 63.

At the tip of the support member 60, a regulating piece 66 having two elongated holes 66a penetrated through its lower part is adjustable in position in the front and back direction with screws 66b, and its upper end is in contact with the fixed shaft 44. installed on.

Note that the elongated hole 66a may be a hollow hole.

Therefore, first, the support member 60 is set on the traverse rod 48 by the mounting screw 61 so that the yarn guide surface 63a of the guide plate 63 matches the yarn running position between the yarn pull-out mechanism and the yarn winding mechanism. At this time, if the screw 66b is loosened and the regulating piece 66 is positioned so that its upper end is in contact with the fixed shaft 44, the wax 64 or the weight 6
When setting up the waxing device again after replacing 5, etc., the thread guiding surface 63a of the guide plate 63 is simply rotated backward until the upper end of the regulating piece 66 comes into contact with the fixed shaft 44. It is set to match the yarn traveling position between the yarn pull-out mechanism and the yarn winding mechanism.

Further, a guide rod 67 for guiding the running of the yarn 42 is fixed to the machine frame 40 above the waxing device on a tangent connecting the outer circumferences of the top roller 46 and the split drum 51.

Therefore, as shown in FIG. 4, even if the yarn 42 is on the outer circumferential surface of the split drum 51 or in the traverse groove 52 during traverse, the yarn 42 is transferred to the guide rod 67.
It only moves back and forth between the top roller 46 and the sprint drum 51, and in the waxing position it always travels on the tangent line connecting the outer periphery of the top roller 46 and the guide rod 67. The wax 64 is not locally damaged, unlike when the thread 37 runs in the traverse groove of the split drum 36, and the wax 64 is uniformly worn away.

The guide rod 67 may be attached to a position outside the tangent line connecting the outer peripheries of the top roller 46 and the split drum 51, as shown in FIG.

In this way, when the yarn 42 pulled out from the spinning chamber 41 by the yarn pull-out mechanism is wound up by the yarn winding mechanism, the weight of the weight 65 and the wax 64 causes the yarn contact surface 64a of the wax 64 and the guide plate 63 to Yarn guide surface 6
The wax 64 is sandwiched between the thread 42 and the thread 3a and waxed, but as the thread 42 runs, the wax 64 is rotated in the direction along the running direction (in the direction of the arrow in FIG. 3).
This rotating action causes uniform wear.

In this manner, when the wax 64 is worn out, in this embodiment, the mounting screw 61 is loosened, the support member 60 is rotated forward, and the weight 65 and the wax 64 are removed as shown by the two-dot chain line in FIG. After turning it upward, the weight 65 is removed and the wax 64 is replaced.

As described above, in the present invention, a regulating piece is attached to the wax supporting member, and when this regulating piece comes into contact with the fixed shaft for supporting the top roller, the wax is held at the optimum waxing position. This invention has the effect of always holding the wax at the optimal waxing position and uniformly waxing the yarn.Furthermore, the present invention has a simple structure and is easy to manufacture because the regulating piece is brought into contact with a ready-made fixed shaft. It has the characteristic of being easy.

It should be noted that, as an embodiment of the present invention and an aspect similar thereto, in addition to the above-described configuration shown in the drawings, the following configuration is also possible.

(a) In the embodiment shown in FIGS. 2 to 5 described above, the guide plate 63 is omitted and the wax 60 of the thread guide portion 60a is
The opposite side surface is used as a yarn guide surface 63a, and the yarn contact surface 64a of the wax 64 is pressed against the yarn guide surface 63a.

(b) In the embodiments shown in FIGS. 2 to 5 described above, the weight 65 is changed to a spring or other pressing member, and the pressing member presses the yarn contact surface 64a of the wax 64 against the yarn guide surface 63a. be configured as follows.

(c) The present invention is configured so that it can be applied not only to the above-mentioned rotary traverse type open-end spinning frame, but also to a quick traverse type open-end spinning frame.
