Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a yarn end processing device that performs a bar winding process and a bunch winding process of a package.

[0002]

[Prior Art]

 In a spun yarn winding machine, a package that is continuously wound up and wound into a fully wound package is sent to a desired next step or shipped as a product. In this package P, as shown in FIGS. 19 and 20, after the thread end is hooked on the slit S at the end of the paper tube K, the bunch winding 1 is performed, and the paper tube K is fed through the nip point N. The main winding 2 is formed in the central portion, and the rod winding 3 is formed on the outer circumference of the main winding 2 by a predetermined length.

By the way, the present applicant has previously proposed a “thread knotting device” for connecting the thread end 5 of the swirl 3 part of the package P to the outer periphery of the package P in the transport path 4 of the package P (Japanese Patent Application No. 62-62). -52162) and a "package thread end winding fixing device" (Japanese Patent Application No. 62-111681) for releasing the bunch winding 1 of the package P (Japanese Patent Application No. 62-111681) have been developed. According to this yarn end processing device Z, the surface layer of the package P including the three winding parts is sucked by the "yarn knotting device" of the stage 1 provided on the transport path 4 for the package P flowing through the transport path 4. The yarn end is released and a bow knot 6 is attached to the outer periphery of the package P, and the bunch winding 1 is released by the "wrapping and fixing device for the yarn end of the package" on the stage 2 so that the bunch yarn end is slit S of the paper tube K. It will be shipped after it has been hung up.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned yarn end processing device, the release of the winding 3 of the package P, the operation of the thread knot (bow knot 6) and the release of the bunch winding 1 are performed on the thread type (denier: thread thickness) of the package P. However, the bow knot of the bow knot 6 is weak and the amount of release thread in the winding part 3 increases due to the difference in thread thickness of the package P flowing through the transport path 4. However, there was a problem that the bunch winding 1 was not released completely.

Specifically, when the thread of the package P is thick, the knot of the bow knot 6 becomes weak because the self-restoring force of the thread is large. In addition, since the thick yarn has a large inertial force when the suction is released, the amount of the suction-released yarn in the rod winding portion 3 becomes large. On the other hand, when the yarn is thin, when the bunch winding 1 is applied with the thin yarn, the yarn bites into the slit S of the paper tube K, so that the release of the bunch winding 1 tends to be incomplete.

The object of the present invention, which was devised in consideration of the above circumstances, is a package that can appropriately release the rod winding, the yarn knot, and the bunch winding according to the yarn type of the package flowing in the transport path. The present invention is to provide a yarn end processing device.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a package winding path for winding a roll wound on the surface of a package, a thread tying means for tying the released thread end to the outer periphery of the package, and a package Bunch unwinding means for releasing the bunch thread wound around the paper core are provided respectively, and in order to perform appropriate rod winding, thread knotting, and bunch unwinding according to the thread type of the package flowing through the transport path. A control unit is provided for changing the rod winding release suction time of the rod winding releasing means, the yarn tying strength of the yarn tying means, and the operating condition of the bunch unwinding means.

[0008]

[Action]

 According to the yarn end processing device for a package having the above-mentioned configuration, the control unit causes the control unit to control the winding time for the winding operation of the winding operation of the winding operation according to the type of the yarn of the package, Also, since the operating conditions of the bunch unwinding means are changed as appropriate, it is possible to perform appropriate rod unwinding, thread knotting, and bunch unwinding regardless of the package yarn type.

[0009]

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

According to the yarn end treating apparatus of the present embodiment, the package P is released from the state shown in FIGS. 19 and 20, and the winding 3 is released, and the main winding after removing the winding is wound around the outer periphery of the package P. The knot as shown in FIG. Further, the bunch winding 1 is removed, and the yarn 1a having a predetermined length is hooked on the slit S at the end of the paper tube K from the nip point N where the bunch winding 1 moves to the main winding 2.

The yarn end processing device A for this package P is: As shown in FIG. 1, a tray 9 with a peg is adapted to be transported on a transport path 4 composed of a roller conveyor or the like. On the peg portion of the tray 9 with pegs, the package P fried by a take-up winder is mounted and supported. The package P is positioned at the positions 0st, 1st, 2st, 3st during the conveyance, and the yarn end processing described later is performed at each position. These positions are referred to as the 0th stage (0st), the 1st stage (1st), the 2nd stage (2st), and the 3rd stage (3st) in order from the left of FIG.

The 0th stage (0st) is provided with surface layer releasing means B for releasing the outermost layer winding 3 of the package P by suction. The first stage (1st) is provided with a thread knotting means C for connecting the released thread end to the outer circumference of the package P. The second stage (2 st) is provided with a bunch unwinding means D for releasing the bunch winding 1 wound around the paper core K of the package P. The third stage (3st) is provided with a bunch processing means E for locking the released bunch thread end 1a in the slit S of the paper tube K.

In the 0th stage (0st), the outermost layer winding 3 of the package P is sucked and released by a suction pipe. The operation of the suction pipe 10 is shown in FIGS. As shown in FIGS. 3A and 3B, when the suction pipe 10 moves in the direction of arrow 11, the suction port 10a of the pipe 10 sucks the yarn end 5 of the rod winding 3. Thereafter, as shown in FIGS. 4A and 4B, the suction pipe 10 is moved to the axial end portion of the package P. Then, the rod winding 3 is axially unwound from the end portion of the package P, and is sucked off while forming the balloon 12 to the suction port 10a of the suction pipe 10 as shown in FIGS. 4 (a) and 4 (b). .. When the thread of the rod winding 3 is used up, the balloon 12 is formed of the thread of the main winding 2, as shown in FIGS. The yarn of the main winding 2 is wound around the paper tube K over a traverse range of a predetermined length. Therefore, in this case, the yarn end of the balloon 13 reciprocates around both ends of the package P while rotating around the outer periphery of the package P. At this time, the thread end of the balloon 13 is captured by the balloon sensor 14 provided close to the outer periphery of the package P, and the presence or absence of the thread is detected to detect the completion of the roll winding. Thereafter, the yarn between the balloon sensor 14 and the package P is cut by the heat cutter, and the operation of the 0th stage (0st) is completed.

The release thread amount of the winding 3 of the package P at the 0th stage (0st) can be appropriately adjusted by adjusting the suction time of the suction pipe 10. For example, if the yarn in the package P is thick, the inertial force at the time of releasing the suction of the yarn is large. Therefore, if the suction time is the same as that of the thin yarn, the suction release yarn amount will increase, so shorten the suction time. .. Conversely, for thin threads, the suction time should be extended.

In the first stage (1st), after sucking and catching the outermost yarn end 16 of the main winding 2 after releasing the winding 3 with a suction pipe, two rings are formed on the outer periphery of the package P, It is designed to perform thread knotting by the comrades. The outline of this thread knot will be described with reference to FIGS. 6 (a) to 6 (f). First, as shown in FIG. 6A, the yarn hooking guide 18 captures the yarn between the suction port 17a of the suction pipe 17 and the package P to form an inner ring 19 and an outer ring 20. Between the yarn hooking guide 18 and the package P, a building device 21 for tying a yarn is arranged. FIG. 6B shows a state in which the inner ring 19 is dropped on the building device 21 and the building device 21 has a hook 22 on the outer ring 20. As shown in FIG. 6C, the hook ring 22 is passed through the inner ring 19 by the building device 21, and in this state, the inner ring 19 is removed from the building device 21 and dropped into the package P. At this time, the inner race 19 is in a state of engaging with the yarn 23 extending from the hook 22 to the yarn hooking guide 18. In this state, when the thread knotting guide 24 is rotated in the direction of the arrow shown in the figure, the inner ring 19 is tightened to the circumference of the package P as shown in FIG. 6 (d). Next, the threading guide 18 sets the thread 23 under the hook ring 22, and in that state, the building device 21 makes a threading ring 23a on the thread 23 as shown in FIG. The thread is tied by passing the through wheel 23a through the hook wheel 22. Then, the knot is tightened by rotating the package P in the direction of the arrow shown while holding the thread knot guide 24 at the rotation position shown in FIG. 6 (e) and supporting the knot so that the knot does not move. The rotation of the package P is achieved by inserting and fixing the paper core K of the package P into the chucker and rotating the chucker. After that, the yarn end at the end of knotting is appropriately cut with a heat cutter to complete the yarn knotting 6 as shown in FIG. 6 (f).

The strength of the knot of the thread knot 6 at the first stage (1st) is determined by the rotation of the package P while the knot is held by the thread knot guide 24 so as not to move, as shown in FIG. 6 (e). It can be adjusted appropriately by adjusting the amount. That is, the knot strength of the knot 6 depends on the return timing for returning the knot guide 24 from the rotation position shown in FIG. 6 (e) to the original position shown in FIG. 6 (c), and the rotation of the package P at that time. It can be adjusted depending on the quantity. For example, if the package P has a thick thread, the self-restoring force of the thread is large. Therefore, if the same "return timing" and "rotation amount of the package P" as the thin thread, the knot strength of the knot 6 is increased. Since it becomes weak, the "return timing" is delayed and the "rotation amount of the package P" is increased. On the other hand, for a thin thread, if the "return timing" is set fast and the "rotation amount of the package P" is set small, it is possible to prevent the knot of the thread knot 6 from becoming too rigid.

In the first stage (1st), the bunch winding 1 wound around the end of the paper tube K of the package P is moved to the main winding 2 side of the package P by the yarn feeding roller, and the bunch winding 3 is released. The operation of preparing for is performed. This is shown in FIGS. As shown in FIG. 7, the nip point N 1 of the yarn bunch wound around the paper tube K of the package P is the uppermost layer (outermost layer), and the yarn start end of the lowermost layer (innermost layer) is formed on the paper tube K. It is fitted in the slit S that has been removed. Therefore, the yarn feeding roller 27 operates to sequentially move the yarn of the bunch winding 1 wound around the slit S from the yarn near the nip point N toward the package P side. That is, as shown in FIG. 7, the tip 27a of the yarn feeding roller 27 contacts the peripheral surface of the paper tube K between the bunch winding 1 and the nip point N, and in that state, is opposite to the winding direction of the bunch winding 1. It revolves in the direction as shown by the arrow in the figure. As a result, the tip 27a of the yarn feeding roller 27 catches the yarn extending from the nip point N to the bunch winding 1, and the thread is sequentially screwed to the position of the tip 27a as shown in FIG. As a result, the starting end of the thread fitted in the slit S is exposed on the surface of the paper tube K.

In the second stage (2st), the bunch thread wound around the paper tube K of the package P is released, that is, the start end of the thread (see FIG. 8) fitted in the slit S of the paper tube K is released. It is supposed to be released. This is shown in FIGS. As shown in FIG. 9, first, the cone-shaped package retainer 28 is moved so as to engage with the end of the paper tube K, and the tip 29a of the thread breaking roller 29 is brought to the surface of the paper tube K near the slit S. Be contacted. In that state, the yarn breaking roller 29 is revolved in the winding direction of the bunch winding 1. As a result, the tip 29a of the yarn breaking roller 29 catches the yarn between the nip point N and the start end of the bunch yarn fitted in the slit S, and the yarn is threadedly moved toward the end of the paper tube K. .. As a result, the bunch thread is loosened. The loosened thread is sucked from the suction port 28a of the package retainer 28 engaged with the end of the paper tube K. Then, as shown in FIG. 10, the package retainer 28 is moved so as to be separated from the end of the paper tube K. Then, as shown in FIGS. 11A and 11B, the yarn YN from the nip point N and the yarn YS fitted into the slit S are pulled out. In that state, as shown in FIG. 12, the chuck ring 30 is pulled down from above the yarns YS and YN. This pulling down is performed until the cone portion 31 of the chuck ring 30 is aligned with the axis of the paper tube K, as shown in FIG. Then, the chuck ring 30 is moved so that its cone portion 31 engages with the end portion of the paper tube K, as shown in FIGS. After that, the thread clamp lever is rotated in the direction of the arrow in the figure, and the thread of the suction port 28a of the package retainer 28 is pressed by this lever. In this state, as shown in FIGS. 13 (a) and 13 (b), when the chuck ring 30 is rotated, the thread chuck lever 33 provided on the chuck ring 30 engages only the thread YS from the slit S. This is captured by pulling out the yarn YS engaged with the slit S as shown in FIGS. 14 (a) and 14 (b). The drawn-out thread is sucked and removed from the suction port 28a of the package retainer 28.

For releasing the bunch winding in the second stage (2st), the releasing force is adjusted by adjusting the revolution speed of the thread breaking roller 29 shown in FIG. That is, when the yarn of the package P is thick, only one or two thick yarns Y are sandwiched between the slits S of the paper tube K as shown in FIG. Even if the rotation speed is small, it can be easily released. On the other hand, when the yarn of the package P is thin, a plurality of the thin yarns y are sandwiched in the slit S of the paper tube K as shown in FIG. 16, so the revolution speed of the yarn breaking roller 29 must be increased. , It cannot be canceled.

In the third stage (3st), the thread YN drawn out from the slit S of the paper tube K is cut into an appropriate length, and the thread YN is engaged with the slit S of the paper tube K again. This is shown in FIG. As shown in the drawing, the yarn YN held by the yarn catching lever 32 at the suction port 28a of the package retainer 28 of the second stage (2st) faces the slit S of the paper tube K through the yarn passing sensor 34. Are biased to match. In the state shown in FIG. 17, when the paper tube K is chucked and rotated by a chucker, the yarn YN is locked in the slit S of the paper tube K. Then, the excess yarn is cut by the heat cutter, and the work is completed.

Due to the 0th stage (0st), the 1st stage (1st), the 2nd stage (2st), and the 3rd stage (3st) described above, the package P flowing through the transport path 4 shown in FIG. The outermost layer winding 3 is sucked and released by the winding means B of the stage (0st), and the yarn end released by the winding means C of the first stage (1st) is tied to the outer periphery of the package P. The bunch winding 1 wound around the paper tube K is released by the bunch winding releasing means D of the second stage (2st), and the bunch thread end released by the bunch processing means E of the third stage (3st) is the paper tube. It will be locked in the slit S of K.

As shown in FIG. 1, the 0th stage (0st) to the 3rd stage (3st) are connected to a control unit 37 that integrally controls each stage. The control section 37 is for performing appropriate rod winding release, thread knotting, and bunch winding release according to the thread type (thread thickness) of the package P flowing through the transport path 4. That is, the control unit 37, depending on the yarn type (thread thickness) of the package P transmitted from the winder of the previous process to the yarn end processing apparatus A, winds the suction pipe 10 shown in FIGS. The release suction time, the return timing of the thread knotting guide 24 shown in FIGS. 6 (a) to 6 (f), the rotation amount of the package P at that time, and the revolution speed of the thread breaking roller 29 shown in FIG. 9 are changed. .. Specifically, the control unit 37 performs the following control according to the thickness of the yarn of the package P.

Thread type (thread thickness) Thick thin suction pipe 10 Short long suction time (FIGS. 3 to 5) Slow and fast return timing of the thread knot guide 24 (FIG. 6) Package P at that time Many rotations few Amount (Fig. 6) Small and large revolution speed of the yarn breaking roller 29 (Fig. 9) By such control, the amount of yarn released from the rod winding 3 of the package P at the 0th stage (0st) is determined by the suction time of the suction pipe 10. Is adjusted as appropriate. That is, for a thick yarn of the package P, since the inertial force at the time of releasing the suction is large, if the suction time is the same as that of the thin yarn, the amount of the suction-releasing yarn increases, so that the suction time is shortened. Conversely, for thin threads, increase the suction time.

The strength of the knot of the thread knot 6 at the first stage (1st) is as shown in FIG. 6 (e), when the package P is held by the thread knot guide 24 so as not to move the knot. By adjusting the rotation amount of, it is adjusted appropriately. That is, the knot strength of the knot 6 depends on the return timing of returning the knot guide 24 from the rotation position shown in FIG. 6 (e) to the original position shown in FIG. 6 (c), and the package P at that time. It is adjusted by the rotation amount and. In other words, when the package P has a thick thread, the self-restoring force of the thread is large. Therefore, if the same "return timing" and "the amount of rotation of the package P" as the thin thread, the knot strength of the knot 6 is increased. Since it becomes weaker, the "return timing" is delayed and the "rotation amount of the package P" is increased. On the contrary, for a thin thread, the knot of the thread knot 6 can be prevented from becoming too rigid by making the "return timing" faster and the "rotation amount of the package P" smaller.

The degree of release of the bunch winding 1 in the second stage (2st) is adjusted by adjusting the revolution speed of the yarn breaking roller 29 shown in FIG. That is, when the yarn of the package P is thick, only one or two thick yarns Y are sandwiched between the slits S of the paper tube K as shown in FIG. Even if the rotation speed is low, it can be easily released. On the other hand, when the yarn of the package P is thin, it is difficult to release because the thin yarn y is sandwiched in the slit S of the paper tube K as shown in FIG. 16, but the revolution speed of the yarn breaking roller 29 is revolved. It can be canceled by increasing.

In summary, according to the yarn end processing apparatus A for the package P having the above-described configuration, the control unit 37 causes the control unit 37 to perform the operations shown in FIGS. 3 to 3 in accordance with the yarn type (thread thickness) of the package P flowing through the transport path 4. The suction time for unwinding the suction pipe 10 shown in FIG. 5, the return timing of the yarn knotting guide 24 shown in FIGS. 6 (a) to 6 (f) and the amount of rotation of the package P at that time, the yarn breaking roller 29 shown in FIG. Since the revolution speed of the orbit is changed, it is possible to perform the appropriate unwinding, thread knotting, and bunch winding release regardless of the package thread type (thread thickness).

By the way, the control section 37 is provided with a display panel 38 as shown in FIG. When the packages P of two types of yarns (A type and B type) flow on the transport path 4, the display panel 38 has a function of displaying the flow status of the packages P. Specifically, on the display panel 38, the positions of the 0th to 3rd stages (0th, 1st, 2nd, 3rd) and the 0th stage, one front, two fronts, three fronts, and four fronts. There are provided a total of 16 button lamps 39 for respectively lighting and displaying the respective thread types (A type and B type). By illuminating each button lamp, the flow status of the package P for each yarn type (A type, B type) can be understood. The illustrated example shows that the yarn type A type is flowing in the front side of the 0th stage, and the yarn type B type is flowing in the 0th to 3rd stages.
