Abstract

PURPOSE: To form a bunch winding by transferring the yarn from a full bobbin to an empty bobbin without damaging the yarn by moving the yarn between a contact roller and the empty bobbin to a bunch winding position outside of a winding width of the empty bobbin in a state of the contact roller and the empty bobbin separated from each another. CONSTITUTION: In the winding operation by a yarn winder 1, the yarn Y is traversed by the stroke of a traverse guide 12, and a winding package P is formed on an empty bobbin B on a winding position. When the yarn is fully wound on the bobbin, a turret is anticlockwisely rotated to switch the empty bobbin B and a full bobbin Bf respectively to yarn switching positions K1, K2. Then a yarn guide for holding a yarn layer is revolved to press the yarn Ya between the bobbins B, Bf, then a bunch winding guide 9 is introduced between a contact roller 6 and the empty bobbin B to control the yarn Yb by moving the same to the bunch winding position of the empty bobbin B. Then the yarn (a) is wound up onto the empty bobbin B by further revolving the yarn guide 8.

Description

YARN TAKE-UP WINDER AND ITS BUNCH WINDING METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spin winder for converting a yarn from a full winding bobbin (package) into a hollow bobbin to form a bunch winding on the hollow bobbin, and a bunch winding winding method thereof.

There exists a conventional spin winding machine shown in FIG. The spinneret 51 of FIG. 12 switches the two bobbin holders 54 and 55 to the winding position M and the standby position T by the rotation of the turret 53, and thus the ball of the winding position M is rotated. The filament yarn Y1 (synthetic fiber yarn) is wound around the bobbin B in the bobbin B. When winding the thread Y1, the contact controller 56 is press-contacted to the ball bobbin B of the bobbin holder 54 of the winding position M, and the thread (1) is traversed by the traverse guide 56 of the traverse device 52. By traversing Y1), it is wound as a package P via the contact controller 56. Moreover, in the spin take-up 51, when it becomes full winding bobbin Bf, by rotating the turret 53, the full winding bobbin Bf is returned to the standby position T, and the empty bobbin B is the winding position M. After switching to, the yarn Y1 is switched from the full winding bobbin Bf to the empty bobbin B.

As shown in Fig. 13, the thread unwinding thread 58 releases the thread Y1 from the traverse device 52 (traverse guide 57) with the thread unwinding guide 58, and the ball bobbin B with the thread catching lever 59. The thread (Y) is gathered toward the bunching winding position (the bunching winding slit) side. In this state, the thread Y1 is positioned on the thread layer of the full winding bobbin Bf with the fixing guide 60, and the bunch Y of the ball bobbin B is subsequently wound with the slide guide 61. By conveying to a slit, the yarn Y1 is switched from full winding bobbin Bf to empty bobbin B. FIG. Then, the yarn Y1 is cut off between the hollow bobbin B and the full winding bobbin Bf, and a bunch winding is formed at the bunch winding position of the hollow bobbin B. FIG.

After the bunch winding is formed, all the guides 58 to 61 are retracted to release the regulation of the yarn Y1. Thereby, the thread Y1 is wound up by the ball bobbin B, returning to the traverse apparatus 52 (traverse guide 57) and traversing again.

In the conventional spin winding machine, in the yarn switching operation, the yarn is switched from the full winding bobbin Bf to the hollow bobbin B by releasing the yarn Y1 from the traverse device 52 (traverse guide 57). To form a bunch winding. Therefore, when the thread Y1 to be traversed is unwound from the traverse apparatus 52, there is a possibility that the traverse guide 57 or the like may be rubbed and damaged. Moreover, when returning the seal Y1 to the traverse guide 57, it will be damaged for the same reason.

If the seal Y1 is damaged during the yarn switching, the quality of the package P is deteriorated.

The present invention is to provide a spin winding machine capable of forming a bunch winding by switching the yarn from a full winding bobbin to an empty bobbin without damaging the yarn, and a bunch winding winding method thereof.

In the present invention, by placing the thread between the contact controller and the ball bobbin in a bunch winding position outside the actual winding width of the ball bobbin, the yarn is converted from a full winding bobbin to a ball bobbin to form a bunch winding on the ball bobbin. will be.

The spin winding machine of this invention and the bunch winding method are demonstrated with reference to drawings.

An embodiment of the present invention will be described with reference to Figs. 1 to 9 with respect to the elastic winding machine of the elastic yarn, and the bunching winding method thereof.

The spin winder 1 of FIGS. 1 and 2 is equipped with a turret 3, two bobbin holders 4 and 5, a contact controller 6 and a traverse device 7, and the gore from the radiator not shown. The winding package P is formed in the ball bobbin B by the elastic yarn Y (henceforth "a thread Y") supplied through the roller. Moreover, the spin winder 1 is a thread layer holding thread guide. (8) and the bunching winding guide 9, the yarn Y is switched from the full winding bobbin Bf to the empty bobbin B, and the bunching winding is formed in the empty bobbin B. Denotes a full winding bobbin (Bf) and a blank bobbin wound as a package (P).

The turret 3 of the spin winder 1 serves as a means for separating the contact controller 6 and the ball bobbin B, and is axially supported by the turret shaft 10 of the base frame 2. The turret 3 is rotationally controlled by a drive source (not shown) connected to the turret shaft 10. Each bobbin holder 4, 5 is axially supported (only one side) by the turret 3, and is provided to protrude from the base frame 2. Moreover, each bobbin holder 4 and 5 is equipped with the ball bobbin B which winds the seal Y as the package P, respectively, and is rotationally driven by a drive source (not shown). Each bobbin holder 4, 5 is switched from the winding position M to the standby position T or from the standby position T to the winding position M by the rotation of the turret 3. The bobbin holders 4 and 5 are also switched to the actual switching positions K1 and K2 located in the middle of the winding position M and the standby position T as shown in Fig. 5C. In addition, although each of the bobbin holders 4 and 5 is usually equipped with a plurality of ball bobbins B, one of the bobbin holders 4 is arranged at the winding position M and the standby position T will be described.

The contact controller 6 of the spin winder 1 is provided in a lifting box 11 which is lifted above the winding position M. As shown in FIG. The contact controller 6 is pressed against the package P (or ball bobbin B) at the winding position M by the lifting box 11, and the seal Y on the supply side is packaged P (or hollow). Guide to bobbin (B). The contact controller 6 is actively driven by a drive source not shown. The traverse device 7 is located on the supply side of the contact controller 6 and is provided with a lifting box 11. The traverse apparatus 7 is provided with the traverse guide 12 which couple | bonds with the yarn Y and traverses the yarn Y. As shown in FIG. The traverse guide 12 is provided with the thread groove 13 which catches the yarn Y like FIG. 2, and is provided corresponding to the number of packages P (hollow bobbin B) of the winding position M. FIG. . In this way, the traverse apparatus 7 captures the yarn Y in the yarn groove 13, and strokes the yarn Y in the traverse width S by reciprocating the traverse guide 12 to the contact controller 6. Traverse toward the winding position (M). (See Fig. 2)

The thread layer holding seal guide 8 of the spin-winder 1 is provided at the thread switching position K in the counterclockwise direction from the winding position M. As shown in FIG. The seal guide 8 extends toward the turret 3 along each bobbin holder 4 and 5 and is axially supported by the guide shaft 18 of the base frame 2. The seal guide 8 is pivoted around the guide shaft 18 by a drive source (not shown).

The bunching winding guide 9 of the spin take-up machine 1 is attached to the tip of the thread layer holding thread guide 8 and is pivoted together with the thread layer holding thread guide 8. The bunching winding guide 9 slides in the axial direction of the bobbin holders 4 and 5.

The seal guide 8 and the bunching winding guide 9 for holding the yarn layer, when the bobbin holders 4 and 5 are positioned at the thread switching positions K1 and K2 as shown in Figs. ) Is converted from full winding bobbin Bf (package P) to ball bobbin B to form a bunch winding on the ball bobbin B. 3 and 4 show that by rotating the turret 3 counterclockwise, the ball bobbin B of the standby position T is moved from the winding position M to the contact controller 6 and the full winding bobbin Bf (package). It arrange | positions between (P)), and the contact controller 6 and the ball bobbin B are separated. In addition, the yarn Y from the traverse device 7 is wound around the full winding bobbin Bf via the contact controller 6 and the empty bobbin B. FIG. Of course, the contact controller 6 and the bobbin holders 4 and 5 are respectively rotated and driven.

In this state, the thread guide 8 for thread holding is pivoted around the guide shaft 18, and closely adhered to the thread Ya between the ball bobbin B and the full winding bobbin Bf. The thread Ya in the cap is captured in the guide groove 19. The guide groove 19 is provided corresponding to the number of empty bobbins B of the bobbin holder 5, and positions the yarn Ya at the winding width center of the full winding bobbin Bf. In addition, the thread guide 8 for thread holding | maintenance keeps the ball bobbin B in contact with the outer periphery of the ball bobbin B while extending the thread Ya by turning around the ball bobbin B.

As a result, the yarn Ya is wound by the thread guide 8 at the center of the winding width of the full winding bobbin Bf (solid layer), and is wound by the hollow bobbin B and cut by extending (Fig. 3). And FIG. 4)

The bunching winding guide 9 enters between the contact controller 6 and the ball bobbin B, and engages the thread Yb between the contact controller 6 and the ball bobbin B to connect the ball Yb to the ball bobbin. Gather and regulate to the bunching winding position (R) of (B). The bunching winding position R is one end of the ball bobbin B and is a position deviating from the traverse width (winding width) S in the traverse guide 12. As a result, the yarn Yb is positioned at the bunching winding position R of the blank bobbin B by the bunching winding guide 9 (see FIGS. 3 and 4).

The yarn Y regulated by the bunching winding guide 9 is cut in the bunching winding position R of the empty bobbin B by cutting the yarn Ya between the empty bobbin B and the full winding bobbin Bf. Bunch is wound up).

Moreover, the bunching winding guide 8 is provided corresponding to the number of the ball bobbin 5 of the bobbin holder 4 and 6, and each thread Yb is attached to the bunching winding position R of each ball bobbin B. As shown in FIG. Collect and regulate.

In this way, the thread guide 8 and the bunching winding guide 9 for holding the floor cooperate to regulate (position) the yarns Ya and Yb with respect to the full winding bobbin Bf and the empty bobbin B. The yarn Y from the traverse apparatus 7 is switched from the full winding bobbin Bf to the empty bobbin B to form a bunch winding on the empty bobbin B. In addition, by entering the bunching winding guide 9 in the same direction as the traverse direction, the yarn Yb is made into the hollow bobbin B without removing the thread Y from the traverse device 7 (traverse guide 12). Can be regulated at the bunch winding position (R).

Next, the bunch winding method of a radio winding machine is demonstrated.

The spin-winder 1 drives the contact controller 6, press-fits the bobbin holder 4 at the winding position M to the contact controller 6, and also drives the traverse device 7 to perform the winding operation. To start. The starting operation traverses the seal Y by the stroke of the traverse guide 12, and forms the winding package P in the hollow bobbin B at the winding position M while guiding it to the contact controller 6. See Fig. 5 (a))

When the package P of the winding position M becomes full winding, by rotating the turret 3 counterclockwise, the ball bobbin B in the standby position T passes through the winding position M and is actually switched. At position K1, the full winding bobbin Bf at the winding position M is passed through the standby position T to the actual switching position K2. At this time, the bobbin holders 4 and 5 are rotated at the rotational speed corresponding to the actual speed. By doing so, the ball bobbin B is brought into close contact with the seal Y and is at a position separated from the contact controller 6. Moreover, the thread Y is wound around the full winding package Bf via the contact controller 6 and the ball bobbin B, traversing in the state coupled to the traverse apparatus 7. (FIGS. (B) and ( c) reference)

When the empty bobbin B and the full winding bobbin Bf are set to the actual switching positions K1 and K2, the spin winding machine 1 starts the actual switching position.

The thread switching operation is brought into close contact with the yarn Ya between the hollow bobbin B and the full winding bobbin Bf (package P) by turning the thread guide 8 for thread holding. At this time, the yarn Ya is captured in the guide groove 19 in the traverse process and positioned at the winding width center of the full winding bobbin Bf. (See Fig. 6).

Subsequently, by placing the bunching winding guide 9 between the contact controller 6 and the ball bobbin B, the thread Yb therebetween is collected at the bunching winding position R of the ball bobbin B and regulated. . At this time, since the seal Yb is regulated in the same direction as the traverse direction, the seal Yb does not come out of the traverse device 7 (traverse guide 12). (See Fig. 7).

As a result, the guides 8 and 9 regulate the yarns Ya and Yb with respect to the empty bobbin B and the full winding bobbin Bf, thereby the yarns are moved from the full winding bobbin Bf to the empty bobbin Bf. ), It is possible to form a bunch winding on the ball bobbin (B). In addition, the thread guide 8 for thread holding prevents the thread Ya from deviating from the winding width (traverse width S) of the full winding bobbin Bf, and wound the rod on the actual layer of the full winding bobbin Bf. To form.

Subsequently, the thread guide 8 for holding the yarn layer is further wound around the bobbin B while increasing the yarn Ya by turning. (See Fig. 8).

In this state, the yarn Ya wound around the ball bobbin B is cut by the tensioning action, so that the yarn switching from the full winding bobbin Bf to the ball bobbin B is completed.

By cutting the yarn Ya in the thread switching operation, the yarn Yb regulated by the bunching winding guide 9 is wound around the bunching winding position R of the bobbin B to form bunching winding ( 9).

When the bunch winding is formed, the respective bobbins 8 and 9 are evacuated from the respective bobbin holders 4 and 5 and the contact controller 6, and then the turret 3 is rotated clockwise to thereby rotate the ball bobbin B. The winding position M and the full winding bobbin Bf (package P) are switched to the standby position T (see Fig. 5 (b)).

As a result, the seal Y is released by the guides 8 and 9, and is traversed again and wound up as the package P in the gazette bin B at the winding position M. FIG. In the standby position T, the full winding bobbin B (package P is taken out of the bobbin holder 4).

In the spin winding machine and the bunch winding method of the present invention, the bunch winding winding guide 9 is coupled to the yarn Yb between the contact controller 6 and the ball bobbin B to allow the yarn Yb to be out of the traverse width. Since the bobbin is moved to the bunching winding position R of the bobbin, the bobbin bobbin Bf is moved from the full winding bobbin Bf to the empty bobbin B without removing the thread Y from the traverse device 7 (traverse guide 12). It is possible to carry out actual switching of the bunch, and to form the bunch winding at the bunch winding position R of the bobbin B. FIG.

Therefore, it is possible to obtain a high quality package P without damaging the yarn Y by removing and returning the yarn Y to the traverse device 7 (traverse guide 12).

Moreover, since there is no withdrawal and return of the yarn Y to the traverse apparatus 7, the success rate of the yarn switching from the full winding bobbin Bf to the empty bobbin B can be improved.

And since the bunching winding is formed with respect to the bunching winding position R of the ball bobbin B with the bunching winding guide 9 in the vicinity of the hollow bobbin B, a regular and clean bunching winding can be formed. In addition, in the case of winding the elastic yarn, since the thread is directly guided to the traverse device 7 by the roller, it is difficult to return to the traverse device 7 when the thread Y is removed from the traverse device 7. The problem does not arise in the invention.

Although the coiling apparatus 1 and the bunching winding method demonstrated that rod winding was centered in the winding width center of the full winding bobbin Bf, it may be any position as long as it does not deviate from the winding width of the full winding bobbin Bf. . Incidentally, the traverse device 7 is not limited to the stroke (reciprocating movement) of the traverse guide 12, but may traverse the yarn Y by, for example, rotating two traverse blade plates.

Next, as a modification of the spin-wound machine, what is suitable for filament yarns (synthetic fiber yarns), such as polyester, is demonstrated with reference to FIG. 10 and FIG.

10 and 11, the same reference numerals as those in Figs. 1 to 9 denote the same members, and the description thereof will be omitted.

The spin winder 31 of FIG. 10 and FIG. 11 is a ball bobbin when a filament yarn Y1 (henceforth "a thread Y1") is switched from a full winding bobbin Bf to a ball bobbin B. FIG. (B) is switched to the winding position M, and the full winding bobbin Bf is switched to the standby position T. FIG. Then, by raising the contact controller 6 in the lifting box 11, the contact controller 6 and the ball bobbin (B) is separated.

In addition, the spinneret 31 is provided such that the same bunching winding guide 9 as shown in Figs. 1 to 9 is removably mounted to be coupled to the seal Y1b between the contact roller 6 and the ball bobbin B. By the bunch winding winding 9, the thread Y1b between the contact controller 6 and the ball bobbin B is moved to the bunch winding position R outside the traverse width of the ball bobbin B (the bunch winding slit 34 We collect in)) and regulate. Then, the yarn winding machine 31 has a fixed thread guide 32 for holding the yarn layer for capturing the yarn Y1a between the bobbin bobbin B and the full winding bobbin Bf, and a slide guide 33 (thread for thread catching yarn). Guide).

The actual switching operation by this spin-winding machine 31 switches the empty bobbin B to the winding position M and the full winding bobbin Bf to the standby position T. As shown in FIG. Subsequently, the contact controller 6 is lifted up by the lifting box 11 so as to be spaced apart from the ball bobbin B. FIG.

In this state, the bunching winding guide 9 enters between the contact controller 6 and the ball bobbin B, and the thread Y1b is collected to just outside the traverse width of the ball bobbin B. At this time, the seal Y1b is in a state of being coupled to the traverse device 7 (traverse guide 12). Subsequently, the fixed seal guide 32 and the slide guide 33 are advanced between the ball bobbin B and the full winding bobbin Bf. Then, the thread Y1b is collected by the bunching winding guide 9 to the bunching winding position R of the hollow bobbin B. The seal Y1a is regulated by the fixed seal guide 32. At this time, the yarn Y does not pull out the yarn Y from the traverse apparatus 7 (traverse guide 12). Thereby, the yarn Y1 from the traverse apparatus 7 is rod-wound on the real layer of the full winding bobbin Bf via the contact controller 6 and the empty bobbin B. As shown in FIG.

Then, it slides with the slide guide 33, and guides the thread Y to the bunching winding slit 34. FIG. In this way, when the seals Y1a and Y1b are regulated by the respective guides 8, 32, 33, for example, the thread in the bunching winding slit 34 by rotating the bobbin holder 5 of the empty bobbin B. Tension is applied to Y1a, the thread is cut, and the switching of the thread is completed. Thereby, the thread Y1 from the traverse apparatus 7 is wound about the bunch winding position R of the empty bobbin B, and forms a bunch winding.

Then, the respective guides 8, 32, and 33 are evacuated from each bobbin holder 4 and 5 and the contact controller 6, and then the contact controller 6 is again moved to the empty bobbin B at the winding position M ( By press-contacting the bobbin holder 5, the thread Y1 traversed can be wound around the ball bobbin B. As shown in FIG. Moreover, in the standby position T, the full winding bobbin Bf (package P) can be taken out.

In the bunching winding method of the spin winding machine of claim 1 and the spin winding machine of claim 3, the bunching winding can be formed on the empty bobbin by switching the yarn from the full winding bobbin to the empty bobbin without removing the thread from the traverse device. Therefore, a high quality package can be obtained without damaging the yarn by loosening or returning the yarn to the traverse device.

In addition, since there is no withdrawal or return of the thread to the traverse device, the success rate of the actual switchover from the full winding bobbin to the empty bobbin can be increased.

In addition, since the bunching winding can be formed on the hollow bobbin in the bunching winding guide in the vicinity of the hollow bobbin, it is possible to obtain a regular and clean bunching winding.

In the spin take-up device of claim 1, the thread extraction guide for the traverse device can be omitted and a simple configuration can be obtained.

In addition, in the spinning machine of claim 2, since the thread between the hollow bobbin and the full winding bobbin is positioned on the thread layer of the full winding bobbin with a thread guide, the yarn is switched without pulling out the thread from the winding width of the full winding bobbin. This can form a bunch winding. And the winding end of a thread can be wound up in a full winding bobbin.
