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, the package P flowing through the transport path 4 has the surface layer of the package P including the three winding parts at the “thread knotting device” of the station 1 installed along the transport path 4. After the suction is released, the thread end is bow-knotted 6 on the outer periphery of the package P, and the bunch winding 1 is released by the "winding and fixing device for the package thread end" of the station 2 to release the bunch thread end from the paper tube K. After being hooked on the slit S, it will be shipped.

[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.

Further, when a plurality of types of packages P having different yarn types are mixed and flowed to the transport path 4, the position of the package P for each yarn type on the transport path 4 is unknown. In other words, there is a problem that the yarn types of the plurality of packages P flowing in the transport path 4 cannot be grasped.

An object of the present invention, which was conceived in consideration of the above circumstances, is to provide a yarn end processing device for a package, which can grasp the position of the package on the conveying path for each yarn type.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a package winding path with winding means for releasing the winding on the surface of the package, a thread knotting means for connecting the released thread end to the outer periphery of the package, and a package knotting means. Bunch unwinding means for releasing the bunch yarn are provided as processing stations, respectively, and a display panel for displaying the position of the package on the transport path for each station and for each yarn type is provided.

[0008]

[Action]

 According to the package yarn end treating apparatus having the above-described configuration, the position of the package on the transport path is displayed on the display panel for each station and for each thread type, so that the thread type of the package flowing on the transport path can be grasped. It will be possible.

[0009]

【Example】

 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.

As shown in FIG. 1, the yarn end processing apparatus A for the package P is configured so that a tray 9 with a peg is transferred onto a transport path 4 including 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 0th, 1st, 2nd, 3rd during the transportation, and the yarn end processing described later is performed at each position. These positions are referred to as 0th station (0th), 1st station (1st), 2nd station (2st), 3rd station (3rd) in order from the left of FIG.

The 0th station (0th) is provided with surface layer releasing means B for releasing the outermost layer winding 3 of the package P by suction. The first station (1st) is provided with yarn tying means C for tying the released yarn end to the outer periphery of the package P. The second station (2nd) is provided with a bunch winding releasing means D for releasing the bunch winding 1 wound around the paper core K of the package P. The third station (3rd) 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.

At the 0th station (0th), 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. 3 (a) and 3 (b), 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. Then, as shown in FIGS. 4 (a) and 4 (b), 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 suction is released while forming the balloon 12 in 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 at both ends of the package P while rotating around the outer periphery of the package P. At this time, the yarn 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 yarn 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 station (0th) is completed.

The amount of yarn released from the winding 3 of the package P at the 0th station (0th) can be appropriately adjusted by adjusting the suction time of the suction pipe 10. For example, for a thick yarn of the package P, since the inertial force at the time of releasing the suction of the yarn is large, if the same suction time as that of the thin yarn is used, the amount of the suction-released yarn is increased, so that the suction time is shortened. On the contrary, for thin threads, the suction time may be increased.

At the first station (1st), the outermost yarn end 16 of the main winding 2 after releasing the winding 3 is sucked and caught by the suction pipe, and then two loops are formed on the outer periphery of the package P. The knitting is done 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 thread hooking guide 18 captures the thread between the suction pipe and the package P to form the inner ring 19 and the outer ring 20. Between the yarn hooking guide 18 and the package P, a bill 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 hook 22 is formed on the outer ring 20 in the building device 21. 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 approximately the same length as the circumference of the package P as shown in FIG. 6 (d). Next, the thread hooking guide 18 guides the thread 23 so as to come under the hook ring 22, and in this state, the building device 21 makes a thread ring 23a on the thread 23 as shown in FIG. The thread is tied by passing the ring 23a through the hook 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 station (1st) is determined by the amount of 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). Can be adjusted as appropriate. That is, the strength of the knot of the thread knot 6 is determined by the return timing of returning the thread 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 "return timing" and the "rotation amount of the package P" are the same as those of a thin thread, the knot strength of the thread knot 6 is weak. Therefore, the “return timing” is delayed and the “rotation amount of the package P” is increased. On the contrary, 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 tight.

In the first station (1st), the bunch winding 1 wound around the end of the paper core K of the package P is moved to the main winding 2 side of the package P by the yarn feeding roller 27, and the bunch is wound. An operation for preparing to release the winding 3 is performed. The situation is shown in FIGS. As shown in FIG. 7, the yarn bunched around the paper tube K of the package P has the nipping point N as the uppermost layer (outermost layer), and the yarn start end of the lowermost layer (innermost layer) is the paper tube K. It is fitted in the slit S formed in the. Therefore, the yarn feeding roller 27 operates so as to move the yarn of the bunch winding 1 wound around the slit S from the yarn near the nip point N toward the sequential package P side. That is, as shown in FIG. 7, the tip 27a of the yarn feeding roller 27 comes into contact with the peripheral surface of the paper tube K between the bunch winding 1 and the nip point N, and in that state, it is in the opposite direction to the winding direction of the bunch winding 1. Is revolved as indicated 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 sequentially advances the yarn to the position of the tip 27a as shown in FIG. As a result, as shown in FIG. 8, the starting end of the thread fitted in the slit S is exposed on the surface of the paper tube K.

At the second station (2nd), 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. 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 bunch yarn starting end fitted in the slit S, and the yarn is threadedly moved toward the end of the paper tube K. To be done. 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 in 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 Y S 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. Then, as shown in FIGS. 13A and 13B, the chuck ring 30 is moved so that the cone portion 31 thereof engages with the end portion of the paper tube K. After that, the thread gripping lever 32 is rotated in the direction of the arrow in the figure, and the thread of the suction port 28a of the package pressing member 28 is pressed by this lever 32. When the chuck ring 30 is rotated in that state, the thread chuck lever 33 provided on the chuck ring 30 engages only with the thread YS from the slit S and captures the thread YS, as shown in FIG. ) Pull out the yarn YS engaged with the slit S as shown in FIG. The pulled-out yarn is sucked and removed from the suction port 28a of the package retainer 28.

To release the bunch winding at the second station (2nd), the releasing force 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, as shown in FIG. 15, only one or two thick yarns Y are sandwiched between the slits S of the paper tube K, so that the revolution speed of the yarn breaking roller 29 is revolved. Even if it is small, you can easily release it. 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 that the revolution speed of the yarn breaking roller 29 must be increased. Cannot be removed.

At the third station (3rd), 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 gripped by the yarn gripping lever 32 at the suction port 28a of the package presser 28 of the second station (2nd) is directed to the slit S of the paper tube K via the yarn passing sensor 34. Are biased to match. In the state shown in FIG. 17, the yarn YN is locked in the slit S of the paper tube K by chucking and rotating the paper tube K with a chucker. After that, the excess yarn is cut by the heat cutter and the work is completed.

Due to the 0th station (0th), the 1st station (1st), the 2nd station (2nd), and the 3rd station (3rd) 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 0th station (0th), and the yarn end released by the winding means C of the 1st station (1st) is tied to the outer periphery of the package P. , The bunch winding release means D of the second station (2nd) releases the bunch winding 1 wound around the paper tube K, and the bunch thread end released by the bunch processing means E of the third station (3rd) is the paper end. It will be locked in the slit S of the pipe K.

As shown in FIG. 1, each of the 0th station (0th) to the 3rd station (3rd) is connected to a control unit 37 that integrally controls each station. The control section 37 is for performing appropriate rod winding release, thread knotting, and bunch winding release in accordance with the thread type (thread thickness) of the package P flowing through the transport path 4. In other words, 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 device A, the rod of the suction pipe 10 shown in FIGS. The unwinding suction time, the return timing of the yarn knot guide 24 shown in FIGS. 6 (a) to 6 (f), the amount of rotation of the package P at that time, and the revolution number of the yarn 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 station (0th) is determined by the suction time of the suction pipe 10. It is adjusted appropriately by adjusting. That is, for the thick yarn of the package P, since the inertial force at the time of releasing the suction is large, if the same suction time as that of the thin yarn is used, the amount of the suction-releasing yarn increases, so that the suction time is shortened. On the contrary, for thin threads, increase the suction time.

The strength of the knot of the thread knot 6 at the first station (1st) is 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). By adjusting the amount, it is adjusted appropriately. That is, the strength of the knot of the thread knot 6 is determined by the return timing of returning the thread 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. Adjusted according to the quantity. In other words, when the package P has a thick thread, the self-restoring force of the thread is large. Therefore, assuming the same "return timing" and "rotation amount of the package P" as the thin thread, the knot strength of the thread knot 6 is increased. Since it becomes weaker, the "return timing" is slowed down and the "rotation amount of the package P" is increased. On the other hand, for a thin thread, the knot of the thread knot 6 can be prevented from becoming too tight by making the "return timing" faster and the "rotation amount of the package P" smaller.

The degree of release of the bunch winding 1 at the second station (2nd) 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, as shown in FIG. 15, only one or two thick yarns Y are sandwiched between the slits S of the paper tube K, so that the revolution speed of the yarn breaking roller 29 is revolved. Even if it is small, 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 increased. By doing so, it becomes possible to cancel.

By the way, the control section 37 is provided with a display panel 38 as shown in FIG. When the packages P of four types of yarn types a, b, c, d flow on the transport path 4, the display panel 38 has a function of displaying the flow status of the packages P for each type of yarn. Specifically, on the display panel 38, the 0th to the 3rd station (0th, 1st, 2nd, 3rd) positions and the 0th, 1st front, 2nd front, 3rd front, and 4th front are displayed. A total of 32 button lamps 39 for lighting and displaying the standby station (,,,) positions are provided for each of the yarn types a, b, c, d. Then, each button lamp 39 is turned on by the yarn type signal from the winder in the previous process, and the position of the package P for each yarn type a, b, c, d can be known.

In the illustrated example, the package P of the yarn type a is flowing through the standby station and the third station 3rd, the yarn type b is flowing through the standby station, and the yarn type c is the standby station and the 0th station 0th. , Indicating that the yarn type d is flowing in the first station 1st and the second station 2nd. The package P of each yarn type is subjected to the yarn end processing according to the yarn type (thread thickness, etc.) at each station as described above.

Here, when the operator visually finds that the thread type of the actual package P is different from the lighting display of the button lamp 39, the reset button 40 is once pressed to erroneously display the lighting. Correctly press the button lamp 39 again. As a result, the button lamp 39 is correctly turned on so as to match the yarn type of the package P, and erroneous yarn end processing is avoided.
