Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding unit in an automatic wine goo, and more particularly to a device for controlling a balloon of yarn unwound from a tube yarn.

The spun pipe yarn is rewound using an automatic winder to remove yarn defects and obtain a package of a predetermined amount or shape.

In this case, the pipe thread supplied to the winding unit is inserted into the peg of the unit in a substantially upright position, and the thread pulled out from the pipe thread has a shape depending on the mass of the central axis of the thread, running speed, air resistance, etc. , the balloon radius, etc. are determined, and it also varies depending on the number of yarn layers of the tube yarn, that is, the difference in the height position of the separation point of the yarn from the yarn layer.

The above-mentioned ballooning of the yarn is performed stably when there is a lot of thread waste in the pipe thread, but becomes unstable as the thread waste decreases and the separation point of the thread from the thread waste shifts to the lower part of the pipe thread. As the distance between the separation point and the yarn guide regulating the upper end of the balloon above the tube yarn increases, the balloon collapses, and knots of the balloon occur at multiple locations, resulting in multiple balloons where the joints of the balloon become threads. Contact the layer surface. For this reason, as the unraveled yarn travels, the unraveled yarn may shift in the axial direction of the tube, ie, so-called loop dropout, resulting in the occurrence of fraying. Once generated, the thread may be wound without being removed, or may cause thread breakage.

The present invention aims to solve the above problems. That is, the present invention forms a wall surface that covers the periphery of the running path of the yarn unraveled from the pipe yarn, and the wall surface is provided with a fluid jet hole, and the fluid flow jetted from the jet hole is directed to the traveling yarn. by controlling the ballooning of the yarn and increasing the unraveling property.
” Nikkirinuki is an attempt to prevent this phenomenon.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a winding unit. The winding unit (1) includes a tube support section (2)
A package (4) for winding the yarn (Y) pulled out from the tube yarn (3) at the support portion position, a traversing drum (5) for driving the package and traversing the yarn, and the like are sequentially arranged. (10) is a suction pipe for yarn splicing, (11) is a relay pipe, which turns to the two-dot chain line position (10a) (lla) and holds the package side yarn end and the tube yarn side yarn end by suction. Each yarn end is guided into the yarn splicing device (9).

In the case of the above-mentioned winding unit, each unit is not provided with a yarn storage magazine, and is transported while being inserted in the carrier (13), and taken into the winding position of each unit and rewound while being inserted in the carrier (13). . Furthermore, the empty bobbin (14) that has been rewound is placed in the car 1 noa (
Empty bobbin discharge conveyor (15) disposed along the unit and discharged from the unit in the state inserted in 13)
transported above.

Therefore, the yarn end of the supplied pipe yarn for splicing is drawn out in advance, and is transported integrally with the pipe yarn while being inserted into the core/tube from the upper end of the pipe yarn. Tube yarn (3) in the above condition
3 - When the carrier (13) is positioned at the rewinding position (2), air is ejected from the air ejection nozzle (16) provided at the lower part of the carrier (13) through the space inside the carrier and hits the tube thread. The yarn end that is spouted into the tube and hanging down is blown up outside the tube, passes through the balloon control member (6), and is sucked and held by the waiting relay pipe (Ila).

The balloon control member (6) has a tube thread (
3) is fixed to a bracket (19) attached to the frame (18) via a bracket (17) with the center axis line aligned with the tube axis/tube axis.

The position of (20) can be adjusted with a long hole. That is, as shown in the third diagram, the balloon control member (6) is composed of a pipe-shaped member having a cylindrical side wall (21) that covers the running yarn, and fluid is ejected onto the inner circumferential surface of the side wall (21). Hole (22)
An opening is formed. Moreover, it is convenient if the ejection hole (22) opens tangentially to the inner circumferential surface (21).

That is, as shown in FIG. 3(a), the fluid injected from the injection nozzle (20) into the internal space (23) of the balloon control member becomes a swirling flow in the direction of the arrow (24), and flows in the direction of the upper and lower opening end faces. A directed spiral flow (25) is generated. If the direction of the swirling flow (24) is the same direction as the direction in which the yarn is unraveled from the tube yarn (3), it will have the effect of reducing the unraveling resistance; In the case opposite to the settling direction, an effect of increasing the unraveling resistance occurs. That is, by generating a swirling flow in the same direction as the unraveling direction of the yarn,
It acts to promote balloon formation of the thread and increase the balloon diameter. Note that the fluid injection nozzle (22)
are formed at two positions above and below the inner circumferential surface, but they can be formed at one place in the center, at two or more places in the axial direction, or even formed as a vertically elongated flat opening. Aspects are possible. In addition, air is used as the fluid, and the air pressure is adjusted as appropriate. (26) is an air supply conduit.

The balloon control member (27) shown in FIGS. 4(a) and 4(b) has a side wall formed in a rectangular or polygonal shape, and has a fluid jet port (28) (2) that jets fluid from the side wall into the internal space.
8) is formed to be inclined and serves to assist the turning movement of the yarn. In this case, the ballooning caused by swirling does not result in a regular cone-shaped balloon, but on the contrary, the balloon collapses and
May result in irregular balloons.

FIG. 5 shows another embodiment of the balloon control member (29).
The cross section is circular as in FIG. 3, except that a thread insertion slit (30) extending over the entire axial direction of the member is provided. If such a slit is provided, the winding unit has a yarn-supporting peg, and the yarn stored in the magazine arranged in each unit is shot, and the yarn end holding suction pipe and peg in the center of the magazine are connected to each other. This is effective when introducing the thread between the tube threads inserted into the balloon control section through the slit (30). Therefore, when the tube yarn still attached to the carrier is transferred to the rewinding position of the unit as shown in Fig. 2, the yarn end is blown upward through the internal space of the balloon control member. Therefore, there is no need to provide a slit (30). Further, the above-mentioned slit (30) can be provided, and the slit (30) is effective when guiding the end of the side yarn by manual operation.

Further, the balloon control member (31) shown in FIG.
) is a substantially truncated conical control member formed by decreasing the cross-sectional area of the thread in the thread running direction.

In other words, the cross-sectional area of the prefectural side (33) is larger than that of the thread pulling side (34), and the area is gradually decreased continuously, and the opening of the fluid jet nozzle (35) formed on the inner circumferential surface is also located on the inner circumferential surface. It is tangential to the surface.

In this case, the flow rate of the fluid ejected from both end openings (33) and (34) is higher than that at the extra person side opening (33) than at the thread exit side opening (34).
Since it tends to be larger, it has the effect of further increasing the swirling force of the ballooning of the yarn pulled out from the tube yarn.

Further, the fluid ejection holes of each of the balloon control members may be provided so as to be inclined toward the prefecture side or the exit side.

Balloon control members of various shapes described above can be applied, and furthermore, the control member can be fixedly attached as shown in Fig. 2, or can be slid in the vertical direction and moved downward as the thread layer of the tube yarn decreases. Alternatively, the annular balloon control member may be cut in the longitudinal direction and the half portions may be connected with a hinge so that they can be opened and closed.

The operation of the balloon control member as described above will be explained with reference to FIGS. 7 to 9. Note that the control member shown in the third figure is used.

Fig. 7 shows the case where the balloon control member (6) is fixed at a fixed position above the thread, and shows the state of ballooning when the amount of thread in the thread decreases, that is, when the thread is pulled out from below the bobbin. show. Note that both the unraveling direction of the thread and the swirling direction of the fluid generated in the internal space of the balloon control member are indicated by arrows (24).
) direction and the same direction.

In this case, the balloon o31) (B
2) Even if the joint (36) is formed, the diameter of the luning, especially the diameter (dl) of the balloon (B2) including the point (P) where the thread separates from the thread waste, increases due to the action of the swirling flow. That is, FIG. 8 shows a simple balloon breaker (37
) and there is no swirling flow, so the diameter of the balloon, especially the diameter of the balloon including the separation point, is extremely small.
The direction of the yarn separating from the yarn waste is along the bobbin (14), and the unraveled yarn tends to come into contact with the surface of the unraveled yarn layer. In contrast, in FIG. 7, the angle between the thread separation point (P) and the axis of the bobbin (hereinafter referred to as separation angle (θ)) is large.

For this reason, the yarn that has unraveled and separated from the yarn layer does not come into contact with the surface of the yarn layer again.

The phenomenon of the number of wheels caused by the unraveling state in FIG. 8 will be explained in FIGS. 12 and 13. Tube thread (
As shown in Figure 12, the unraveling of the yarn from 3) is of the type in which the separation point traverses a substantially constant width (5) from the upper yarn layer and gradually moves downward (42). It is common. In such a case, as shown in Figure 13, the separation point of the thread moves alternately in the directions of arrows (37) and (38), and during unraveling in the direction of arrow (37), which moves from top to bottom, There is no problem, but especially when unraveling along the direction of arrow (38), for example, the outermost layer yarns (Yl) (Y2) to (Yn) are unraveled sequentially starting from yarn (Yn). Y2)
is unraveled, and when the upper thread (Yl) is unraveled, the separation point moves in the direction of the arrow (37). Gold thread (Y
2) When the balloon is released and pulled out, if the balloon is insufficient and the separation angle (θ) is small, it may contact the upper thread (Yl) (
Q) There are times when the ring-shaped thread (Yl) is slightly loose.
) is dragged by the unraveled thread, and the separation point does not move properly, causing the thread (Yl) to fall out along the bobbin (14) in a loop shape. A so-called ring-like phenomenon occurs.

Therefore, as shown in Fig. 7, if the balloon (B2) is sufficiently formed and the separation angle (e) is large, the loosened thread (Y) will come into contact with the upper thread again as shown in Fig. 13. The separation point of the yarn moves while drawing a spiral locus around the surface of the yarn waste, without causing any ring-like formation due to separation from the yarn layer.

The formation of the balloons (B1) and (B2) is performed by controlling the control member (6).
), and the lower end opening (6a) of the control member (6) increases due to the swirling flow in the same direction as the yarn waste direction.
The balloon radius is further increased under the action of the fluid flow flowing out from the balloon (FIG. 3 (25)). The influence of the above-mentioned swirling flow decreases as the number of yarn layers decreases and it is located below the bobbin.

For this reason, as shown in Figure 9.10, the balloon control member (
6) is moved as the thread waste changes, the balloon of the thread separated from the thread waste maintains a large separation angle (θ) and becomes a stable balloon. That is, the member (
6) is moved. That is, the distance (L) in Figure 7
The ratio n, (11) and (12) is small, and unraveling can be performed without reducing the influence of the swirling flow on the yarn separation point. Note that the balloon control member can be moved by controlling the fluid cylinder, rack, and pinion. Incidentally, pseudo S -11= The reason why the above drive needs to be performed independently for each winding unit is because the winding state in each winding unit is independent of each unit.

The embodiment shown in Figure 11 is an example in which the entire tube thread is surrounded by the balloon control member (39), and the balloon is stably generated without moving the member (6) in Figure 9.10. It is something. That is, the balloon control member has a circumferential side wall (40) having a diameter sufficiently larger than the maximum layer diameter of the tube, and has a length approximately equal to the entire length of the yarn layer of the tube, Fluid ejection holes (41) are formed at a plurality of locations on the circumferential surface (40) to generate swirling airflow in the same direction as the unraveling direction of the yarn. In this case, member (39)
can be made integral, but when applied to a winding unit, the cylindrical member may be divided in half and each semi-cylindrical member may be connected by a hinge, or It is desirable to be able to combine and separate in a link style.

12- As described above, according to the present invention, the wall surface substantially covers the periphery of the running path of the thread unraveled from the pipe yarn, and the wall surface is provided with a fluid ejection hole, and the fluid ejection hole is formed in the wall surface. Since a balloon control member is provided that controls the ballooning of the yarn by applying the ejected fluid flow to the running yarn, it promotes the formation of a balloon of the yarn that is unraveled from the pipe yarn, and the separation point between the yarn and the yarn waste is In this method, the unraveled yarn does not come into contact with unraveled yarn, and balloon collapse, loop formation, etc. can be prevented, and a high-quality wound package can be obtained.
