Description

Plier device and pliers driving method {FLYER DEVICE AND FLYER DRIVING METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plier device used when threading from a package or to burning by twisting, and in particular, any position of the thread mounting position of the upper end and lower end of the package and the winding diameter of the package. The present invention relates to a pliers device capable of suppressing tension fluctuations and further suppressing balloon fluctuations.

As is well known, conventionally, when simply threading from a package, or when twisting by threading from a package like a multi-twist machine, it is configured to rotate along with the yarn made from the package and guide the thread. A pliers are used. The conventional pliers are configured to rotate by the tension of the yarn made from the package, and are of the so-called small-pole driving method (free rotation method).

The pliers of the conventional small-pole driving method have a low sea tension when the seam position (the seam point) of the seal in the package is moved to the upper side, and the surface of the package is changed when the seam position is moved to the bottom side of the seal. In this stage, the sear tension is increased, and at the stage where the winding diameter of the package is large, the sear tension is low, and when the winding diameter of the package is small, the sear tension is increased. It is pointed out as a problem.

Thus, if tension fluctuations occur during thread failure, the balloon widens during low tension. For example, in a quadruple twister, the inner balloon and the outer balloon come into contact with each other, which is a major cause of thread breakage. It became.

In addition, when the yarn is threaded from the package, the yarn is made to rub the outer layer of the package. Thus, if tension fluctuations occur at the time of yarn breakdown, it becomes a large cause of lint generation.

Thus, the present invention is intended to solve the above-mentioned problems, and by directly connecting a rotation drive source to the pliers, actively driving the pliers in synchronism with the actual speed, and thus the upper and lower sides of the package. It is therefore an object of the present invention to provide a pliers for suppressing tension fluctuations, suppressing balloon fluctuations, and suppressing the cause of thread breaking regardless of the position and the winding diameter of the package.

As a preferred embodiment of the present invention, the pulse measuring counter 38 is formed by a disk member fixedly attached to the pliers support 40, for example, as shown in FIG. It consists of the form which divided into several radiation at space | interval. The pulse measuring counter 38 is designed as, for example, 30 counts of one round or 60 counts of one round.

In this way, the pliers rotation drive source 43 made up of the pliers F and the motor M3 is connected between the one-way clutch mechanism 42 and the pliers rotation drive means FRM by connecting the one-way clutch mechanism 42 to the free rotation. Assembling is carried out by focusing on the fact that the pliers have a high speed and low tension when the upper side position P1 of the package P is shown as shown in FIGS. 2A and 3A. ), The tension is not applied when the pliers are rotated before the upper side of the package P. Therefore, the tension is not affected by the package diameter, It becomes substantially constant irrespective of the upper side position P1 and the lower side position P2.

As a specific structural example mentioned above, the pulse measuring counter 38 shown in FIG. 1A and 1B is provided with respect to the said 3rd rotation drive system structure part 13, The pulse measuring counter 38 and the said stop meter The detection means 39 provided in the component portion 14 feeds back the motor 3M in the pliers rotation driving means FRM.

In the quadruple twisting machine T provided with the pliers drive method FA consisting of the above-mentioned structure, the yarn Y1 made from the package P is the yarn guide part Fa of the pliers F, and the 3rd.

In this case, the seal Y1 formed from the package P forms the trajectory of the inner balloon IB between the tensor 41 and the inner port structure 27, and forms the outer port structure 19. Between the balloon guide BG and the balloon guide BG, the trajectory of the outer balloon OB is formed. The seal Y1 formed from the package P includes a third rotary drive system component 13 including the pliers FA and a second rotary drive system component 12 including an inner port structure 27. In the course of passing through the first rotational drive system component 11 including the outer port structure 19 and the balloon guide BG, four twisted yarns Y2 are provided.

The pliers driving method according to the present invention will be described in detail the method of controlling the rotational speed of the pliers. First, in a multiple twister equipped with a positively driven pliers, when the start switch for operating the twister is turned ON, the pliers drive motor which uses the self-generating means as the driving power for the start of the apparatus is operated for about 5 seconds. There is a time when the pliers are free to rotate without being driven to an extent. At the start of this operation, the actual speed is obtained. For example, a pulse measuring counter that counts six pulses with one optical sensor is provided, and the frequency is included by the number of times counted for five seconds. After 5 seconds, the pliers drive motor is driven to about 80% of the obtained frequency. Thus, by slowing the rotational speed of the pliers drive motor can be prevented from excessive rotation of the pliers too fast.

Thereafter, the time of each pulse (1/6 revolutions) is measured a predetermined number of times, and the difference between the maximum time and the minimum time at that time is obtained. For example, if the difference is 50 msec or more, the rotation speed of the pliers drive motor is increased. It is judged to be too slow, so raise the frequency slightly. For example, if the difference is less than 50 msec for a predetermined number of times, the frequency of the pliers driving motor is reduced too little for the purpose of preventing the rotation speed of the pliers drive so fast that it rotates by one week.

In this way, the rotational speed of the pliers drive motor is measured for a predetermined time at the start of rotation, and the rotational speed of the predetermined ratio (about 80%) of the measured rotational speed is controlled and set to the initial setting value of the motor driving speed. By comparing the rotational speed during operation measured by the rotational speed measurement means with the set rotational speed, a new rotational speed is automatically set according to the rate of change.

Subsequently, the pliers driving method according to the present invention is based on Figs. 4A and 4B, 5A and 5B, in relation to the variation in sea tension as compared to the free-rotating pliers driving method without a conventional rotation driving source. We compare and examine about.

4 is a graph in which the horizontal axis represents time, the vertical axis represents tension (hereinafter, the same), and the tensile waveform diagram showing variation of sea tension in a situation in which the package P has a large diameter (about φ 135 to φ 133), Fig. 4A is a graph showing variation in sea tension by a free-rotating pliers having no conventional rotational drive, and Fig. 4B is a graph showing variation in sea tension by an active rotational pliers having a rotational drive of the present invention. . FIG. 5 is a tension waveform diagram showing variation in sea tension in a situation in which the package P has a small diameter (about 48 to φ 46), and FIG. 5A is a free rotating pliers having no conventional rotational drive source. It is a graph which shows the fluctuation of the sea tension, and FIG. 5B is a graph which shows the fluctuation of the sea tension by the positive rotary pliers which have the rotation drive source of this invention.

As apparent from these FIGS. 4A and 4B, 5A and 5B, irrespective of the winding diameter of the package P, the positively rotary pliers having the rotational drive source of the present invention shown in FIGS. 4B and 5B are shown. The sea tension is approximately constant during the sea fault period (during the reciprocation between the upper position P1 and the lower position P2 of the package), and the conventional rotary drive source shown in the graphs of FIGS. 4A and 5A is shown. It has been found that the free-rotating pliers, which do not have, have a dramatic result compared to the large fluctuations in the sea tension during the sea period.

In short, the pliers driving method according to the present invention, as shown in Fig. 6, in the operation start stage of the multi-twisting machine, the pliers are microscopically rotated, the rotational speed of the pliers is measured by the rotational speed measuring means, and the initial rotational speed Is set to about 80% of the measured value, and the measured value is compared with the set value. If there is no difference for a predetermined period (when the measured value does not exceed the set value), the deceleration is commanded, and if a difference occurs (the measured value is set). If it exceeds the value, it is configured to command the increase.

According to the pliers of the present invention according to the above configuration, it becomes possible to drive the pliers at an optimum rotational speed for threading, and the pliers rotate following the thread even if the thread is rotated rapidly, so that the thread This can be done without imparting tension, and breaking of the thread can be prevented as much as possible.

In addition, according to the pliers according to the present invention, when the yarn wound on the bottom of the package, the yarn is peeled off by the pliers, so that the yarn is wound on the package surface, compared to the conventional seaming method. In addition, the lint of the thread can be prevented from occurring and at the same time, the balloon does not fluctuate. Moreover, in the quadruple twisting machine in which the inner balloon IB and the outer balloon OB are formed, the contact of the inner balloon IB and the outer balloon OB by tension fluctuations at the time of sea fault can be prevented, It can be said that it works very effectively also in the point which can prevent a break.

This can be done without imparting excessive tension to the thread, and the thread breaking can be prevented as much as possible.

In addition, according to the power generation system of the motor-driven pliers according to the present invention, when the yarn wound on the lower part of the package, the yarn is peeled off by the pliers so that the yarn is wound on the package surface. Compared to the above method, lint of the thread can be prevented from occurring and at the same time, the balloon does not fluctuate and works very effectively even at a stable point. Moreover, in the quadruple twisting machine in which the inner balloon IB and the outer balloon OB are formed, the contact of the inner balloon IB and the outer balloon OB by tension fluctuations at the time of sea fault can be prevented, and a thread break is carried out. It can be said that it works very effectively also in the point that it can prevent.

In addition, according to the pliers driving method of the present invention, it is effective in setting the optimum rotational speed according to each threading condition of each weight of the multi-burst machine, and drives the pliers at the optimum rotational speed for threading. In addition, the pliers rotate according to the thread even if the thread is rotated quickly, so that it can be done without applying excessive tension to the thread and can be prevented from breaking.
