Description

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

Generally, yarn spun using an open-end spinning machine and wound onto one bobbin is finally knitted into a woven fabric or knitted fabric by being passed through a loom, knitting machine, etc.

However, especially during knitting, when the threads come into contact with knitting needles or guides that operate at high speeds, large frictional resistance is applied to the threads, causing yarn breakage and fluffing, which impede the operation of the knitting machine. , causing scarring.

In order to eliminate such problems in the process ζ after spinning, wax is applied to the yarn spun from the spinning chamber on the open-end spinning machine when it is wound onto the bobbin. A waxing device that provides smoothness has long been desired.

In order to meet such demands, for example as shown in FIG. 35 is provided protrudingly, and a wax 31 is rotatably attached to the shaft pin 35 so that one surface is on a tangent connecting the outer peripheries of the top roller 32 and the split drum 36, and the weight of the wax 31 causes the top roller 32 to and the split drum 36.
A waxing device has been proposed which applies tension to the thread 37 and applies wax to the thread 37.

However, in the conventional waxing device described above, as shown in FIG. 1, the yarn 37 that is wound while being traversed by the split drum 36 is traversed by the split drum 36, and as a result of this traverse, the yarn 37 is traversed and wound onto the outer periphery of the split drum 36 and its traverse groove 36a. Since the yarn 37 moves back and forth between the top roller 32 and the split drum 36 by moving in and out of the inside, when the thread 37 runs inside the traverse groove 36a of the split drum 36, the wax 31 is partially There were defects in that the threads 37 were not uniformly abraded and were not evenly coated with wax.

The present invention was made in order to eliminate such defects in the conventional waxing device, and its purpose is to remove waxing from the top roller and the split drum on the tangent line connecting the outer circumferences of the top roller and the split drum, or at a position outside of the tangent line connecting the outer circumferences of the top roller and the split drum, that is, from the machine frame. A guide rod for guiding the running of the yarn is arranged at a separate position, and the thread contact surface of the wax is arranged on a tangent line connecting the outer periphery of the guide rod and the top roller, and further, the wax is connected to the outer periphery of the split drum. By arranging the guide iron at a position inside the tangent line connecting it to the outer surface of the supported thread guide member, unlike conventional devices, the thread does not move back and forth at the waxing position, and the wax is evenly worn away. The present invention provides a waxing device for an open-end spinning machine that allows the wax to be uniformly applied to the yarn, and that allows the yarn to be smoothly guided from the outer surface of the yarn guide member to the yarn contact surface of the wax. It is about providing.

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 drawing-out mechanism for drawing upward the yarn 42 spun from the spinning chamber 41, and winding while traversing the yarn 42 pulled out by the yarn-drawing mechanism. The yarn winding mechanism includes a yarn winding mechanism for taking 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 configuration of the waxing device, which is the main part of the present invention, the configuration of the yarn drawing mechanism and yarn 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 2 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 the above-mentioned 1 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 contact area 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 thread 42 spun from the spinning chamber 41 is caught by the thread hooking part 47 of the top roller 46 and guided between the top roller 46 and the pull-out roller 43,
The thread 42 is connected to the thread guide groove 49 of the traverse rod 48.
Since the yarn 42 is traversed 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, and the top roller 46 It will not be locally worn away.

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 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 at a certain rate between the thread drawing mechanism and the thread winding ladder. As the spindles rotate, all the spindles are wound onto the bobbin 55 at the same time without being traversed along 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 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 spindle of this waxing device will be explained with reference to FIGS. 2 to 5.
8, a support member 60 with an inverted L shape on the side is attached with a 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 so as to be orthogonal to the traverse plane of the yarn 42 and to be inclined downwardly thereto.

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

Also, like the guide plate 63, it is rotatable on the support shaft 62,
In addition, the wax 64 in the shape of a tenon disc made of paraffin or the like, which is attached so as to be movable in the axial direction, 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. The yarn comes off the tip of the yarn guide portion 60a, is locked to the yarn contact surface 64a of the wax 64, and is then guided between the yarn contact surface 64a of the wax 64 and the yarn guide surface 63a of the guide plate 63. The state is ready for waxing.

The tenon disk-shaped weight 65 is rotatably attached to the support shaft 62 and movable in the axial direction, 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.

In this embodiment, to replace the weight 65, loosen the mounting screw 61 and rotate the support member 60 forward, so that the weight 65 and wax 64 are in the upward position as shown by the two-dot chain line in FIG. Just replace it.

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., simply rotate the support member 60 in the direction until the upper end of the regulating piece 66 comes into contact with the fixed shaft 44, and the thread guide surface 63a of the guide plate 63 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 filament 42 is fixed to the machine frame 40 at a position 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.
Whether it is on the outer periphery of the split drum 51 or in the traverse groove 52, the yarn 42 is attached to the guide rod 67.
The yarn only moves back and forth between the top roller 46 and the split 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 strip 37 is the traverse groove 36a of the split drum 36.
The wax 64 is not locally damaged unlike when the wax 64 is run inside, but is evenly worn away, and the threads 4
2, uniform waxing will be performed.

Further, the mounting position of the guide rod 67 is located on the outside of 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. and the outer surface of the thread guide portion 60a.

Therefore, when the yarn is inserted into the wax, the yarn contact surface 64 of the wax 64 is guided by the outer surface of the yarn guide portion 60a.
Since the yarn 42 being moved to the thread guide portion 60a does not come into contact with the guide rod 67 during its sliding, it can smoothly move on the outer surface of the yarn guide portion 60a with less resistance and reach the wax 6.
The fibers are quickly and reliably guided to the yarn contact surface 64a of No. 4.

If the yarn comes into contact with both the guide rod 67 and the yarn guide portion 60a, the movement resistance will be large, causing a problem that the yarn will not be introduced to the yarn contact surface.

As described above, the present invention provides a method for forming the yarn at a position on or outside the tangent line connecting the outer periphery of the top roller and the split drum, and at a position inside the tangent line connecting the split drum and the outer surface of the yarn guide section. Unlike conventional devices, a guide rod is arranged to guide the running, and the yarn contact surface of the wax is placed on a tangent line connecting the outer periphery of the guide rod and the top roller, so that the yarn moves back and forth at the waxing position. This makes it possible to uniformly abrade the wax without damaging the wax locally, apply the wax uniformly to the yarn, and quickly transfer the yarn from the outer surface of the yarn guide to the yarn contact surface of the wax. Moreover, it has an excellent effect of being able to lead reliably.

Note that the present invention is not limited to the waxing device in which the wax 64 is mounted on the traverse rod 48 by the support member 60 as in the above-mentioned embodiment, but is also applicable to the wax 64 in the conventional wax 64 mounted on the fixed shaft 44 by the support arm 45. It can also be applied to a waxing device configured to be attached to.
