Description

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

As shown in FIG. 1, for example, as a waxing device for a conventional open-end spinning machine, a support piece 34 is formed protruding from the side of a support arm 33 that supports a top roller 32. A shaft pin 35 is provided in a protruding manner, and a wax 31 is rotatably attached to the shaft pin 35 so that one surface thereof is on a tangent connecting the outer peripheries of the top roller 32 and the split drum 36. While applying tension to the thread 37 running between the top roller 32 and the split drum 36,
There was also 1 which had 7 coated with wax.

However, in the conventional waxing apparatus described above, as shown in FIG. The tension is different between the traverse position (both traversed end positions) and the traverse center position, and the tension is particularly small at the center position, causing slack and separation from the wax surface.

Therefore, there is a drawback that the yarn 37 cannot be uniformly waxed.

Therefore, as a method to eliminate such defects in conventional waxing devices, a yarn guide surface that matches the yarn running position between the yarn pull-out mechanism and the yarn winding mechanism is provided, and the yarn guide surface is A conceivable method is to arrange the wax rotatably so that the thread contact surfaces are in opposing contact with each other, and to sandwich the thread between the thread guide surface and the thread contact surface of the wax for waxing. Threading between the guide surface and the wax thread contact surface poses a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a new waxing device for an open-end spinning frame that can easily thread yarn between a yarn guide surface and a yarn contact surface of wax.

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

Hereinafter, one embodiment of the waxing device for an open-end spinning frame of the present invention will be explained with reference to FIGS. Spinning chamber 4 for spinning sliver
1, a yarn pulling mechanism for pulling out the yarn 42 spun upward from the spinning chamber 41, a yarn winding mechanism for winding the yarn 42 pulled out by the yarn pulling mechanism while traversing it; It consists of a waxing device disposed at a yarn running position between a yarn drawing mechanism and a 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 pulling 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 an appropriate 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 a top roller 46 that slides in sliding contact with the circumferential surface of the pull-out roller 43 is rotatably supported at the tip of each support arm 45, respectively.

In addition, a part of one side peripheral edge of these top rollers 46 has
As shown in FIG.
A thread hook part 47 is formed to guide the thread between the thread and the thread.

A traverse rod 48 common to all weights 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 contact area between the pull-out roller 43 and the top roller 46. A large number of thread guide grooves 49 are formed in each spindle for locking and traversing the thread 42.

Therefore, when the thread 42 spun from the spinning chamber 41 is caught by the thread hook 47 of the top roller 46 and guided between the top roller 46 and the pull-out roller 43, the thread 42 is Since the yarn 42 is traversed by the yarn guide groove 49 of the traverse rod 48 and pulled upward by the top roller 46 and the pull-out roller 43, the contact portion of the yarn 42 with the top roller 46 changes continuously. The top roller 46 is not locally worn away by the yarn 42.

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

Further, a large number of split drums 51 each having a driver groove 52 are fixed to the outer periphery of the rotating shaft 50 for each spindle, and as the rotating shaft 50 rotates, the thread drawn upward from the thread drawing mechanism is fixed. Article 42 is to be traversed.

One support frame 53 is provided corresponding to each split drum 51.
A bobbin 55 that slides into contact with the surface of the split drum 51 and rotates in the direction of the arrow in FIG. installed as possible.

- Therefore, the thread 42 drawn upward by the thread drawing mechanism is guided to the split drum 51 while traveling at a certain rate between the thread drawing mechanism and the thread winding mechanism, and As the spindles rotate, they are not traversed according to the traverse groove 52, but are wound onto the bobbin 55 all at the same time.

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 split drum 51. The yarn is wound by a yarn winding mechanism, and a waxing device is provided for each spindle at a yarn running position between the yarn pulling-out mechanism and the yarn winding mechanism, and the yarn 42 is wound by the yarn winding mechanism. The yarn 42 has previously been coated with wax.

Next, the embodiment of one weight of this waxing device will be explained with reference to FIGS. 2 to 5. The traverse rod 4
8, a support member 60 with an inverted side surface is mounted on the mounting screw 61.
is attached, and the attachment angle position of the support member 60 can be arbitrarily adjusted by loosening and tightening the attachment screw 61.

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

A substantially disk-shaped guide plate 63, which is rotatably and axially movably attached to the support shaft 62, has a yarn guide surface 63a on its inner surface, 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,
Moreover, the wax 64 in the shape of a circular disc made of paraffin or the like is attached movably 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 caught 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 yarn 42 is locked at an appropriate position on the outer surface of the thread guide section 60a as shown in FIG. The yarn guide portion 60a is moved off the tip of the yarn guide portion 60a, and is stopped by the yarn contact surface 64a of the wax 64, and then between the yarn contact surface 64a of the wax 64 and the yarn guide surface 63a of the guide plate 63. It is guided and becomes ready for waxing.

The disk-shaped weight 65 attached to the support shaft 62 so as to be rotatable and movable in the axial direction is because the support shaft 62 is inclined downward toward the traverse plane of the yarn 42. 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.

Therefore, when the yarn 42 running between the yarn guide surface 63a of the guide plate 63 and the yarn contact surface 64a of the wax 64 is traversed by the split drum 51, it becomes slack at the center position. Without a doubt,
Waxed evenly.

Furthermore, since the yarn contacting surface 64a of the wax 64 is always pressed against the yarn 42 by the weight 65, the wax 64
4. Even if the wax goes down, uniform waxing can always be performed.

Further, the yarn contacting surface 64a of the wax 64 is connected to the guide plate 63.
The pressing force for pressing against the yarn guide surface 63a can be arbitrarily changed by replacing the weight 65 with one having a different weight.

That is, in order to replace the weight 65 in this embodiment, the mounting screw 61 is loosened, the support member 60 is rotated forward, and the weight 65 and wax 64 are placed in an upward position as shown by the two-dot chain line in FIG. Just replace it.

Therefore, by replacing the weight 65 with one of a different weight, the contact pressure of the yarn contacting surface 64a of the wax 64 against the yarn 42 can be adjusted as desired, and the amount of wax applied to the yarn 42 can be adjusted arbitrarily depending on the type of yarn. It is possible to adjust to.

Moreover, this pressing means is not limited to the weight 65,
A spring or other suppressing member may be used as long as the pressing force can be changed arbitrarily.

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 rear direction with a screw 66''b, and its upper end abuts against the fixed shaft 44. It is installed so that

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

Therefore, first, the support member 60 was set on the traverse land 48 by the mounting screw 61 so that the yarn guiding surface 63a of the guide plate 63 coincided with the yarn traveling position between the yarn pulling-out mechanism and the yarn winding mechanism. 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, wax 64 or weight
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 pulling-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 64 and the split drum 51.

Therefore, as shown in FIG.
Even if the yarn 42 is on the outer circumference of the split drum 51 or in the traverse groove 52, the thread 42 only moves back and forth between the guide rod 67 and the split drum 51, and is always attached to the top roller 46 in the waxing position. Since the yarn 37 travels on a tangent line connecting the outer periphery of the guide rod 67 and the guide rod 67, the yarn 37 runs along the traverse groove 3 of the split drum 36 in an open-end spinning machine without a guide rod as shown in FIG.
The wax 64 is not locally damaged as is the case when traveling inside the yarn 6a, and is uniformly worn away.Moreover, the yarn 42 is uniformly waxed.

The guide rod 67 may be mounted outside the tangent line connecting the outer peripheries of the top roller 46 and the split drum 51, as shown by the two-dot chain line in FIG.

When the yarn 42 pulled out from the spinning chamber 41 by the yarn drawing 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 to touch the guide plate 63. Yarn guide surface 63
At this time, 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), and this rotational action uniformly worn away.

As described in detail above, the present invention provides a support member with a yarn guide section located in the traverse range of the yarn, and the inner surface of the similar guide section has the yarn guide section approximately parallel to the traverse plane of the yarn. A guide surface is provided, and a disk-shaped wax is rotatably attached to the similar thread guide surface so that the end surface of the wax disk contacts the thread contact surface, and the thread is inserted between the similar thread guide surface and the thread contact surface. holding the
The tip of the yarn guide section is made to correspond to one end of the traverse range of the yarn and is located inside the outer peripheral edge of the wax, and the yarn that is in contact with the outer surface of the yarn guide section is passed through the tip of the similar guide section. In order to guide the yarn to the yarn contacting surface of the wax, the outer surface of the yarn guide section is formed to become lower toward the tip, thereby guiding the yarn between the yarn guiding surface and the yarn contacting surface of the wax. It has an excellent effect of making it easy to hang.
