Description

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

Conventionally, as shown in FIG. 1, a waxing device for an open-end spinning machine, for example, has a support piece 34 projecting from the side of a support arm 33 that supports a top roller 32. A shaft pin 35 having an enlarged diameter portion 35a that can be contracted at its tip is provided protrudingly, and the shaft pin 35
On the other hand, one side is the top roller 32 and the split drum 36.
A wax 31 is rotatably attached so as to be on a tangent line connecting the outer periphery of the top roller 32 and the splint drum 36, and the weight of the wax 31 applies tension to the thread 37 running between the top roller 32 and the splint drum 36. There is a waxing device that applies wax to the yarn 37.

However, in the conventional waxing device described above, the wax 31 is attached to the shaft pin 35 as shown in FIG. , when replacing the worn wax 31 with a new one, the shaft pin 35
The wax 31 had to be attached to and removed from the shaft bottle 35 by reducing the diameter of the enlarged diameter portion 35a with a finger or the like, and replacing the wax was extremely troublesome.

In addition, since the thread 31 is inclined toward the front (in the direction away from the machine frame) as it goes upward, the support pin 35 of the wax 31 faces upward as it approaches the machine frame, and therefore, it is either the machine frame side or the side from which the wax is removed. However, it was inconvenient to use a structure in which only the wax was simply attached and detached.

Therefore, it may be possible to tilt the wax support member, but this has the problem that the structure is complicated and manufacturing is difficult.

The present invention has been made in order to eliminate the defects in conventional waxing devices, and its purpose is to enable the thread guide member to be pulled upward from the support member with the wax still attached, thereby making it easier to replace the wax. It is easy to perform, the structure can be simplified by eliminating the need for locking means for the support member and thread guide member, and the wax can be easily and easily moved to the waxing position so that the thread contact surface of the wax matches the thread running position. It is an object of the present invention to provide a new waxing device that can be set accurately and that can be easily maintained and inspected.

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

Hereinafter, an embodiment of a waxing device embodying the present invention in an open-end spinning machine will be explained with reference to FIGS. A spinning chamber 41 for spinning a sliver provided therein, and a yarn 4 spun from the spinning chamber 41.
2 upward, a thread winding mechanism for traversing and winding the thread 42 pulled out by the thread drawing mechanism, and a thread winding mechanism between the thread drawing mechanism and the thread winding mechanism. It consists of a waxing device placed in the running position.

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 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 41 for guiding the thread is formed between the wire and the wire.

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 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 of each spindle for locking and traversing the yarn 42.

Therefore, when the yarn 42 spun from the spinning chamber 41 is hooked on the yarn hooking part 41 of the top roller 46 and guided between the top roller 46 and the pull-out roller 43, the yarn 42 is traversed. Since the thread is traversed by the thread guide groove 49 of the rod 48 and pulled upward by the top roller 46 and the pull-out roller 43, the top roller 46 is not locally worn by the thread 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 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 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 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. Previously, wax is applied to the yarn 42. Next, an embodiment of this waxing device for one spindle is shown in FIGS.
Referring to FIG. 4, the traverse rod 48
A support member 60 having an inverted L shape on the side surface is attached to the top by a mounting screw 61, and the mounting angle position of the support member 60 can be arbitrarily adjusted by loosening and tightening the mounting screw 61.

A fitting groove 62 is formed in the upper part of one side of the support member 60, and a support plate 63 is attached with two screws 64 so as to cover the fitting groove 62 from the side.

Further, a receiving groove 63a is cut out at a position corresponding to the fitting groove 62 in the upper center of the support plate 63.

The proximal swelling portion 65a is removably fitted into the fitting groove 62 of the support member 60, and the inner surface of the thread guide member 65 supported by the receiving groove 63a of the support plate 63 (opposed to the machine frame 40) A support shaft 66 is protruded from approximately the central position so as to be perpendicular to the traverse plane of the yarn 42 and to be inclined downwardly thereto.

A substantially disc-shaped guide plate 67, which is rotatably attached to the support shaft 66 and movable in the axial direction, has a yarn guide surface 67a that is connected to the yarn between the yarn drawing mechanism and the yarn winding mechanism. It is arranged to match the row running position.

A substantially disk-shaped wax 68 made of paraffin or the like is attached to the support shaft 66 so as to be rotatable and movable in the axial direction, and its thread contact surface 68a is connected to the thread pulling mechanism and the thread winding mechanism. The thread guide surface 67a of the guide plate 61 is arranged so as to be in contact with the thread guide surface 67a of the guide plate 61.

Similar to the guide plate 67 and the wax 63, a substantially disc-shaped weight 69 is attached to the support shaft 66 so as to be rotatable and movable in the axial direction.
Since the wax 68 is inclined downward toward the traverse plane, its weight acts to press the yarn contact surface 68a of the wax 68 against the yarn guide surface 57a of the guide plate 61.

Note that the yarn contacting surface 68a of the wax 68 is connected to the guide plate 6.
The pressing force for pressing against the first thread guide surface 57a can be arbitrarily changed by replacing the weight 69 with one having a different weight.

Moreover, this suppressing means is not limited to weight 69,
A spring or other pressing member may be used as long as the pressing force can be changed arbitrarily.

Therefore, in order to replace the worn out wax 68 with a new one in this waxing device, as shown in FIGS.
The yarn guide member 65, which is fitted into the support plate 63 and supported by the receiving groove 63a of the support plate 63, is pulled out upward along the fitting groove 62 and removed from the support member 60 to remove the yarn that is difficult to replace with wax. After separating from the traveling position, the weight 69 can be removed from the support shaft 66 and the wax 68 can be replaced.
Wax replacement becomes very easy.

Next, in order to attach the thread guide member 65 in which the wax 68 has been replaced to the support member 60, the proximal end swelling portion 65a of the thread guide member 55 is inserted into the fitting groove
2 from above until it is supported by the receiving groove 63a of the support plate 63, the yarn contacting surface 68a of the wax 68 is at the waxing position that matches the yarn running position, as shown in FIG. , the wax 68 can be set accurately.

Note that the weight 69 may be replaced in the same manner as the wax 68 described above, and the thread guide member 65 may be replaced.
Since the wax 68 and the weight 69 can be removed from the support member 60 while being integrated, maintenance and inspection can be easily performed.

Further, as shown in FIG. 4, the outer surface of the thread guide member 65 is formed in an oblique shape that becomes lower toward the distal end, and the guide plate 67 has a shape such that its outer peripheral edge does not protrude from the distal end of the thread guide member 65. It is formed to the size and wax 68
are formed in such a size that their outer peripheral edges slightly protrude from the tip of the thread guide member 65.

Therefore, when the thread 42 is hooked on the thread hooking portion 47 of the top roller 46 and held between the toggle roller 46 and the pull-out roller 43, the thread 42 is caught on the outer surface of the thread guide member 65. When the thread 42 is traversed, it is guided along the outer surface of the thread guide member 65 toward its tip as shown in FIG. The yarn contacting surface 68a of the wax 68 is latched thereto, and then the wax 68 is guided between the yarn contacting surface 68a of the wax 68 and the yarn guiding surface 67a of the guide plate 61, so that it can be laid.

In this way, the present invention disposes a support member corresponding to the thread running position between the thread drawing mechanism and the thread winding mechanism, and also provides a thread guide member to which wax is removably attached relative to the support member. It is fitted together with the wax so that it can be pulled out upwards, and a thread guide surface is provided on the inner surface of the similar guide member, that is, on the side of the machine frame, so as to be at approximately the same position as the running position of the thread in the waxing state. By bringing the yarn contacting surface of the wax into contact with the yarn guide surface, the yarn running position is such that it is difficult to replace the wax by removing the yarn guide member from the support member with the wax attached to the yarn guide member. Since the wax can be separated from the thread, it is easy to replace the wax, and the structure can be simplified by eliminating the need for locking means between the support member and the thread guide member.Furthermore, the thread contact surface of the wax is The wax can be accurately set at the waxing position so as to match the traveling position, and maintenance and inspection can be easily performed.

Furthermore, the present invention is not limited to the above-mentioned open-end spinning machine,
It is also possible to apply it to a yarn winder.
