In this way, the number of threads at the return point B is realized by the auxiliary guides 106 and 107, and the number of threads at the return point A is realized by the auxiliary guides 108 and 109.

When a thread break occurs upstream in such a traverse apparatus, the thread of the traverse apparatus is loosened, the number of threads at the return point is not performed as described above, and the thread is fed through the return point, and the thread is rotated. I may be wound up at the root of

If the winding of the thread occurs, it is necessary to remove the wound thread. However, since it is wound around a narrow space between the drive device as a source of the rotating blade, it cannot be removed unless the traverse device is separated, and there is a problem that the removal takes time and effort.

Accordingly, the present invention has been made in view of the above problems of the prior art, and provides a traverse device capable of preventing the thread from being carried around the return point when the thread breaks, to be wound on the root of the rotating blade. It aims to do it.

It is a figure.

In general, the traverse apparatus includes a plurality of traverse units U1, U2, U3,... It is arranged in a row in the horizontal direction. One traverse unit U1 is shown in FIG.

Reference numeral (1) is a seal guide disposed on the left and right of the traverse center, reference numeral (2) is located on the upper side and rotating blade rotating in the counterclockwise direction around the traverse center (01), reference numeral (3) is the lower side Rotation blade rotated clockwise around the center eccentric from traverse center (01), reference numeral (4) is the auxiliary guide of the return point (A), reference numeral (5) is the auxiliary guide of the return point (B) , Reference numeral 6 denotes a heater as a thread cutting device cut and installed from the lower surface of the seal guide 1 to a position passing through the return point B, and reference numeral 7 denotes a heater on and off. Control device for controlling the, reference numeral 8 is installed on the lower surface of the seal guide (1), is an apostle regulation guide for forming an apostle across the heater (6), these are the main part of one traverse unit have.

In addition, reference numeral 11 is a touch roller or pre-cushion roller, the reference numeral 12 is a bobbin holder, the reference numeral 35 is a bobbin mounted on the bobbin holder 12, and the reference numeral P is a bobbin 35. The package is wound on. Reference numeral 15 is a bracket for supporting the auxiliary guide 4 via the block 16. Reference numeral 17 is a bracket for supporting the auxiliary guide 5 via the block 16.

As shown in the cross-sectional view of the return point B of FIG. 3, the heater 6 is a plate heater embedded in the lower surface of the seal guide 1, as long as the molten resin thread passes through the lower surface of the heater 6. It can generate calories locally. In Fig. 1, the thread to be thrown up and wound around the return point B from the upper rotating blade 2 at the time of thread disconnection is tangential from the thread guide 1 toward the housing part of the root of the rotating blade 2. It is wound while forming an apostle in the direction (arrow (a)). Thus, the heater 6 is installed at a position crossing the slope of the arrow a toward the root of the rotating blade 2.

The more downstream the thread to be melted with the heater 6 is, the better. Moreover, it is preferable to make the area of the heater 6 small. Therefore, an arc-shaped projection guide 8 in the shape of an arc is provided near the return point B as the lower surface of the seal guide 1. The apostle of the thread from the touch roller 11 to the arrow a is bent by the apostle regulating guide 8, and the thread through the apostle regulating guide 8 is located just below the heater 7, and wound All the yarns are melted on the downstream side and the winding is stopped.

The control device 7 controls the heater 6 on and off. Although the heater 6 can be always ON, power consumption increases. Thread breakage is often known statistically or empirically that it is likely to occur during some kind of operation of a winder with a traverse device attached thereto. Thus, the control device 7 of the winder with the traverse device turned on the heater only for a predetermined time before and after the timing at which the thread break is likely to occur during operation of the winder.

For example, a traverse device is attached to a spin winder in the case of a system configuration in which yarns of synthetic fibers are wound by an emitter, a co-trol furnace and a spin winder. It is also assumed that the spin-winding machine has an autorevo function for automatically transferring the thread from the full-scale bobbin to the public bobbin, and has a thread hooking device for hanging the thread by manual operation at the first start. In such a system, the timings where thread breakage is likely to occur are due to autoleverism and thread hanging. Therefore, the heater 6 is turned on (ON) at the timing when the autorevo starts (when the bobbin holder is inserted into the bobbin holder) or when the manual threading starts (the bobbin holder is started). The heater 6 is turned off at a predetermined time of 5 to 20 seconds after the end of the revo or the end of the threading.

When a thread break occurs in such a system, when the sensor detects the occurrence of thread break, all the traverse units U1, U2, U3,... The yarn to be cut is cut and the yarn from the emitter is aspirated. That is, when thread break occurs, the thread about 4 to 5 m toward the spin take-up becomes free (free) and enters the traverse apparatus. The winding control guide 8 of the heater 6 as the thread cutting device described above is used to prevent the thread from being wound to the rotating blade. The thread cutting device is not limited to the heater 6 but may be a mechanical cutter.

Next, the state of the yarns at the return points (return points) A and B will be described. As shown in the state diagram of the return point (return point) A of FIG. 2, the seal guide 1 is positioned above and below the upper and lower rotary blades 2 and 3, and the upper and lower rotary blades 2 and 3 are respectively An auxiliary guide 4 protruding downward from the side of the touch roller 11 is located below. That is, the auxiliary guide 4 is disposed only on the traverse center side with the traverse trajectory interposed therebetween. And the whole is arrange | positioned so that the slope of the upper and lower sides of the thread Y may cross obliquely along the touch roller 11. At this return point (return point) A, a thread may be threaded from the lower rotating blade 3 to the upper rotating blade 2. In the point (C), the rotating blade 2 traverses the yarn to the right in FIG. 1 according to the seal guide 1. The role of locking the thread to the upper rotating blade 2 is provided by the seal guide 1, and the seal guide 1 not only determines the traverse trajectory, but also assists the number of threads. Since the auxiliary guide 4 which assists the water supply of the thread together with the thread guide 1 only peels off the thread from the lower rotating blade 3, the degree of bending of the thread in the auxiliary guide 4 is It is restrained to the minimum so as not to interfere with water supply.

When thread breakage occurs, the thread loosens on the upstream side, so that the lower rotating blade 3 winds up the thread when the thread is turned over from the lower rotating blade 3 to the upper rotating blade 2. Is less likely. Therefore, in this part, arrangement | positioning of the heater as a thread cutting device is abbreviate | omitted. However, the heater as a thread cutting device can also be provided in this part.

As shown in the state diagram of the return point (return point) B of FIG. 3, the structure in which the seal guide 1 is arranged on the upper and lower rotary blades 2 and 3 of the other degree of protrusion is the same as that of the second. Do. However, the auxiliary guides 5 on the lower side of the rotary blades 2 and 3 are positioned to protrude inward from the side of the half touch roller 11. That is, the auxiliary guide 5 is arranged only on the opposite side of the traverse center side with the traverse trajectory interposed therebetween. At this return point B, a thread may be transferred from the upper rotating blade 2 to the lower rotating blade 3. In the point (D), the rotating blade 3 traverses the yarn to the left in FIG. 1 in accordance with the seal guide 1. Removing the thread from the upper rotating blade 2 is held by the thread guide 1, and the seal guide 1 not only determines the traverse trajectory, but also assists the number of the thread. Since the auxiliary guide 5 latches the thread on the lower rotating blade 3, the degree of bending of the thread in the auxiliary guide 5 is larger than that of the auxiliary guide 4. Thus, since the thread guide 1 and the auxiliary guide 4 are on both sides along the traverse trajectory, as is clear from the contrast with FIG. 2, the bending of the thread is not simply a "shaped" but zigzag.

When thread breakage occurs, the thread loosens on the upstream side, so that the upper rotating blade 2 winds up the thread when the thread is transferred from the upper rotating blade 2 to the lower rotating blade 3. high portential. For this reason, the heater 6 as a thread cutting device is provided in this part. Moreover, in order to secure the apostle through this heater 7, the apostle regulation guide 8 is also arrange | positioned.

Moreover, in order to reduce the difference of the free length between the upper and lower rotating blades 2 and 3 and the touch roller (or pre-cushion roller) 11, the upper and lower rotating blades 2 and 3 are provided close to each other. . Therefore, the seal guide 1 is provided above the upper and lower rotation blades 2 and 3, and the auxiliary guides 4 and 5 are provided below the upper and lower rotation blades 2 and 3. . As a result, the distance between the tip of the rotating blades (2) and (3) and the touch roller (pre-cushion roller) 11 becomes approximately equal at the left and right return points (return points), and the actual movement in the traverse direction by the free length is achieved. By delaying the left and right equally, the left and right shape of the package end can be the same.

In addition, at the left and right return points (return points) A and B, the overlaid rotary blade 2 in the counterclockwise direction and the rotary blade 3 in the clockwise direction carry over threads which carry threads in opposite directions. As shown in the diagram, the thread is turned over. By providing an extremely short overlap section, the seal becomes free at the time of the thread delivery and naturally returns to the center position of the traverse width by the mounting force, thereby preventing the collapse of the package shape due to the unstable traverse width.

In this way, if the thread guide 1 is disposed on the upper and lower rotary blades 2 and 3, and the overlap section is installed at the return points A and B on the left and right sides, Since the winding of the thread by the rotary blades 2 and 3 easily occurs, the heater 6 as the above-described thread cutting device is effective.

In addition, the detailed structure of the traverse apparatus which carries out the thread between the up and down rotation blades at the left and right return points (return point) of a traverse trace, and another example of heater arrangement are demonstrated with reference to FIGS. do.

In FIG. 4, the upper rotating blade 2 is slightly smaller than the lower rotating blade 3, even if the upper and lower rotating blades 2 and 3 are inclined, and the rotating blades 2 and 3 are respectively. The tip of is almost in line with the vertical apostle (Y). The upper rotating blade 2 has two tip ends 2a, 2b 180 degrees apart as a point object with respect to the center 01, and the lower rotating blade 3 is a point object with respect to the center 02. It has two tips 3a and 3b 180 degrees apart. The upper rotating blade 2 has a center 01 and the lower rotating blade 3 has a center 02 positioned on a reference line 13 by a distance ε. And perpendicular | vertical to the reference line 13, the line through the center 01 becomes the traverse center line 14 in the upper rotating blade 2.

In this way, due to the deviation of the center 01 and the center 02, at the return point (return point) B, the number of threads of the thread is conducted from the upper end 2a to the lower end 3a. In addition to the name of the lower end 3a at the return point (return point) A, the upper end 2b also reaches the return point (return point) A. As a result, the two guides 2a, 2b, 3a, and 3b are threaded together with the thread guide 1 and the auxiliary guide 4 between the rotating blades 2 and 3 in the reverse direction. The thread is rounded up according to the traverse trace determined by (5). The number of tips of the rotary blades 2 and 3 is not limited to two, but may be three tips arranged equally to 120 °, and one rotary blade has two tips and the other. The rotating blade may have three tips, and the angular velocity of the rotation may differ in inverse proportion.

Auxiliary guides (4) and (5) to assist the water supply (closing) of the thread through the bracket attached to the seal guide (1) are disposed below the rotary blades (2) and (3). (1) and the auxiliary guides (4) and (5) are intended to lift the rotating blades (2) and (3) in the vertical direction. The auxiliary guide 4 has an outward guide face 4a, and the auxiliary guide 5 has an inward guide face 5a toward the traverse center 01. As shown in FIG. In addition, the bracket 15 of FIG. 1 has a guide surface 15a for deviating from the traverse trajectory according to the seal guide 1, and the bobbin guide and the thread pullinger not shown in the bobbin change by the rotation of the crete It is a surface holding the thread peeled off from the rotating blades (2) and (3) by the action of the guide. When the guide surface (15a) is present, the thread is not traversed so that the punch winding of the end of the bobbin (35) is formed. It is. When the thread slides off the guide surface 15a, the traverse starts with the above-described method.

In addition, the driving mechanism for rotating the rotating blades (2) and (3) in the opposite direction to each other will be described with reference to Figs. In FIG. 5, the central shaft 23 is rotatably supported with respect to the substrate 21 via the bearing 22. In addition, the hollow body 25 is rotatably supported with respect to the substrate 21 via the bearing 24. In addition, the drive shaft 27 is rotatably supported with respect to the substrate 21 via the bearing 26. This drive shaft 27 is rotationally driven by the pulley 28. A timing pulley 29 is provided on the pulley 28 side of the drive shaft 27, and a gear 30 is attached to the half pulley 28 side. Then, a timing pulley 32 meshing with the timing belt fastened to the timing pulley 29 is attached to the central axis 23, and the central axis 23, i.e., the lower rotating blade 3 is the same as the drive shaft 27. Rotate in the direction. In addition, a gear 33 engaged with the gear 30 is attached to the hollow body 25, and the hollow body 25, that is, the upper rotating blade 2 rotates in the opposite direction to the drive shaft 27.

In Fig. 6, the gear ratios of the gears 30 and 33 and the dimension ratios of the timing pulley 29 and the timing pulley 32 are equal, so that the upper and lower rotation blades 2 and 3 are at the same angular velocity. Rotate in reverse. Reference numeral 34 denotes an idle pulley for applying tension to the timing belt 31.

In the driving mechanism of FIG. 5 described above, a heater (2) is disposed on the lower surface of the housing part 21a which covers the outer side of the hollow body 25 to which the upper rotating blade 2 is attached and partitions the space between the rotating blades 2. 9) is buried. The position seen from the upper surface of the position of this heater 9 is shown in FIG. It is a horseshoe-shaped heater 9 located on the outer circumference of the housing portion 21a at the root of the rotating blade 2, and the front side is an open end. In Fig. 6, the yarn wound at any of the left and right return points (return points) A and B is intended to be wound around the outer housing part of the hollow body having the gear 33, but the yarn is heated by the heater 9. Since it passes through the lower surface, it is melted by the heater 9. By arranging such a heater 9, it is possible to cope with the winding of the yarn at the left and right return points A and B.

7 is a view showing a winding prevention mechanism instead of a thread cutting device. The air nozzle 10a, 10b which opens toward the outer side below the seal guide 1 in the part past the left and right return points A and B is provided. Air nozzles 10a and 10b function as slope changing means for changing the slope of the loosened yarn outward by the injection of air from the air nozzles 10a and 10b.

If the thread is loosened and the thread is loosened, and the thread which is to be entered beyond the return point (A) or (B) of any of the rotating blades (2) and (3) is loaded on the air stream, the winding Resolved. However, air nozzles 10a and 10b are disposed at positions past the return points (return points) (A) and (B) so as not to affect the normal thread return.

Each of the air nozzles 10a and 10b is configured to blow compressed air from an air source to on (0N) of the solenoid valve device 10c. On / off of the solenoid valve device 10c is controlled by a control device ( 7) is performed.

The timing of turning on and off the solenoid valve device 10c is set at a predetermined time before and after the operation of the machine for causing thread breakage, as explained in FIG. However, it is always irrelevant. In addition, the air nozzles 10a and 10b may not only change the slope to the outside by taking out (blow), but also change the slope by sucking the division to be wound on the rotating blade.

In the above-described embodiment, the thread cutting device or the slope changing means applied to the traverse device in which the thread guide is provided on the upper side of the two rotating blades has been described. However, as described in FIG. Even in the traverse apparatus provided with the seal guide, the thread cutting device or the slope changing means of the present invention can be applied.

As described above, in the invention of claim 1, when the thread breaks, the thread cutting device cuts the thread to be wound around the return blade (return point) to the housing part of the rotation blade. Coiling of cutting edges is prevented. As a result, it is freed from the troublesome work of removing the wound thread which disassembles and performs the rotating blade traverse apparatus.

In the invention of claim 2, in addition to the effect of claim 1, since the thread cutting device is a heater, the thread of the synthetic resin is melted instantaneously, and the ON of the heater further includes a timing at which thread breaking occurs. Since it is limited to a predetermined time, it does not consume unnecessary energy, and it exhibits the effect that a thread can be reliably melted when needed.

In the invention of claim 3, in addition to the effects of claim 1, the thread cutting device guides the thread wound from the blade to the thread cutting device when the thread is broken, to limit the thread cutting device to the required place. It has the effect of being able to excrete and simplify a structure.
