Description

A spin winder

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spin winder that twists and unwinds a thread released from a sudden yarn package, and more particularly, to a spin coil having a function of detecting thread breakage of a wound yarn.

Conventional spinners are of two types, one additional side by side with one sudden yarn package 106 as shown in FIG. 7 and the second side by side with two sudden yarn packages placed in two stages as shown in FIG.

In Figs. 7 and 8, the various winding machines are formed with the winding device 103 arranged side by side above the spindle device 102, and the two additional windings are installed so as to face each other. It is installed in parallel.

Spindle device 102 is composed of a rotating disk 105 that rotates at a high speed by a drive belt (not shown), a stop plate on which one or two steep packages 106 are placed, a balun guide 107, etc. The thread (Y) released from the (106) enters the tension device (108) located in the center and is tensioned, and is twisted twice by the rotating disk (105) rotating at a high speed to reach the upper balloon guide (107). . In addition, the winding device 103 includes a guide roller 109 and 110, a supply roller 111, a traverse guide 112 for traverse, a winding drum 113 driven and rotated, and a winding package P. It consists of a supporting cradle 114.

The combustible thread Y is traversed in the traverse guide 112 via the guide rollers 109 and 110 and the supply roller 111, and moves to the winding drum 113 to come into contact with the winding package P. do.

In addition, a drop wire 115 is provided between the spindle device 102 and the winding device 103. The drop wire 115 rotates in the direction (a) shown when the yarn feeding package 106 is empty or the thread is broken, and detects that there is no thread by the limit switch SW. By detecting the absence of the seal in this way, the controller 116 connected to the limit switch SW controls the opening and closing of the switching valve 117 to operate the air cylinder 118 to the link arm 119 which rotates. The winding package P is separated from the winding drum 113 by the rotation of the cradle 114, thereby stopping the winding up. When the drop wire 115 breaks and rotates by gravity, the drop wire 115 is pressed to the upper end of the tension device 108 to prevent further pulling out of the thread.

However, in the conventional spin winding machine shown in Figs. 7 and 8, the drop wire 115 for detecting the breakage of the yarn Y is placed on the movement path of the yarn between the spindle apparatus 102 and the winding apparatus 103. Installation is limited by the array.

In the radiation winding machine shown in Fig. 8, although the yarns Y released from the two sudden yarn packages are twisted twice after being braided, the drop wire 115 is moved to the movement path of the yarn wound by the winding device 103. In the case of detecting the thread breakage, it is difficult to sufficiently detect when a single yarn break occurs in which one of the yarns 106 is broken. Although single thread breakage is also detected using a sensor for detecting the thread thickness, the arrangement of the sensor is limited between the guide roller 109 and the supply roller 111 in which the thread runs stably. In addition to receiving, it is expensive.

The winding apparatus of the present invention is designed to detect thread breaks without being limited in arrangement.

In order to solve the above problems, in the present invention, the spinneret of claim 1 is provided with one additional yarn package in parallel with each other, and the yarns released from the yarn package of each weight in the stationary state of the spindle means of each weight. In the spin-winding machine which is wound and wound around the sudden-emergency package by rotation, the drive unit which rotates a spindle means in each weight, the detection means which detects the load of each drive means, and each detection means And discriminating means for discriminating the thread break by the load to be detected.

For this reason, the load of the drive means which fluctuates by the tension of a thread | capacitance, etc. can be detected, and the presence or absence of thread breakage can be discriminated.

The method according to claim 2, further comprising a plurality of yarn feeding package side by side, while the yarn released from a plurality of yarn feeding package of each weight in a stationary state, while the ball means around each of the plurality of yarn feeding packages by the rotation of the spindle means of each weight In the spin-winding machine wound up and twisted together, the drive means for rotating the spindle means in each weight, the detection means for detecting the load of each drive means, and the discrimination for discriminating the thread breakage by the load detected by each detection means It is provided with a means.

For this reason, the load of the drive means which fluctuates according to the tension of a thread | capacitance, etc. can be detected, and the presence or absence of thread breakage can be discriminated. In particular, when determining the presence or absence of thread breakage by detecting the load of the drive means of each weight, detection of single yarn breakage, which has been difficult in the past, can be easily and accurately performed.

In Claim 3, the said discriminating means has the threshold value of the thread breaking determination set according to the load of the drive means at the time of winding up a thread | capture at a constant speed.

Therefore, it is possible to cope with various winding machines having different numbers of times and the size of the spindle diameter of the spindle means without requiring the change of the limit value.

In Claim 4, the threshold value of thread break determination is set according to the detection load after a predetermined time has elapsed since the start of winding.

For this reason, threshold values are individually set for each weight in accordance with the load in a stable state, and appropriate thread breaking determination is performed for each weight having a different condition.

The belt 25 is wound around the fifth pulley 22 and the sixth pulley 24 of the support shaft 23, and the supply roller 26 of the winding device 2 is spaced apart from the support shaft 23 at a predetermined interval. It is stuck.

Moreover, the continuously variable transmission 17 is connected to the cam box 27 which converts a rotational force into reciprocation motion, and the reciprocating rod 28 is connected to the cam box 27. As shown in FIG. In the reciprocating rod 28, the traverse guide 29 which traverses the thread Y combusted by the spindle apparatus 2 and winds around the winding package P rotated by the pressure welding of the winding drum 21 has a predetermined space | interval. It is stuck and stuck. Moreover, the winding package P is folded with respect to the winding drum 21 by the folding device 30 provided in each weight. Thereby, the output of the winding motor 4 is transmitted to each of the support shafts 18, 23 and the reciprocating rods through the pulleys, the belt, the transmission 11, the continuously variable transmission 17 and the cam box 27. 28, the winding drum 21 and the supply roller 26 are rotated to traverse the traverse guide 29 by reciprocating.

As the drive motor 6 of each weight, an induction motor, a DC brushless motor, or the like is used, and is connected to each spindle device 2 of each weight.

The spindle device 2 includes a stationary plate 31 on which one yarn feeding package 8 is placed, a tensioning device 32 for imparting a predetermined tension to the yarn Y released from the yarn feeding package 8, and a drive. It consists of a rotating disk 33 connected to the output shaft of the motor 6. As shown in FIG. 3, these drive motors 6 and the spindle device 2 are connected via the coupling 36 to the output shaft 6A of the drive motor 6 which is a DC brushless motor. A rotating plate 33 may be connected, and a stop plate 31 on which an emergency feeding package 8 is placed is provided on the output shaft 6A of the drive motor 6, which is a DC brushless motor, directly through the bearing 35. The rotating disk 33 is fixed to the output shaft 6A below.

Thereby, when driving the drive motor 6 of each weight, as shown in FIG. 2, the thread Y unscrewed from the yarn feeding package 8 enters the tension apparatus 32 located in the center, and tensions it. Is provided, and it is ballooned in the rotating disk 33 which rotates at high speed, and reaches the upper balloon guide 37. As shown in FIG. As shown in FIG. 2, the yarn Y from the yarn feeding package 8 is twisted once from the tension device 32 to the rotating disk 33, and the rotating disk 33 is removed from the rotating disk 33. Another twist is made up to the balun guide 37, and it is twisted twice in total, from the balun guide 37 through the guide rollers 38, 39 and the supply roller 26, and the traverse guide 29 It is wound in the winding package (P) which is traversed by the rotation to the winding drum (21). As shown in Fig. 2, the winding package P includes a link arm 41 that can be installed between the winding package P and the winding drum 21, and an air cylinder for rotating the link arm 41. As shown in FIG. Comprising (42) and the conversion valve 43 for supplying and supplying air to the air cylinder 42, by rotating the link arm 41 by the air cylinder 42, winding the winding package (P) drum Fold from (21). In this way, the link arm 41 is inserted between the winding package P and the winding drum 21 to lift the winding package P. The friction between the link arm 41 and the winding package P is increased. The winding package P can be stopped in a short time.

On the other hand, the control system 7 for controlling the drive of each of the motors 4 and 5, as shown in Fig. 2, the driver 46 of the control box 45 and the drive motor 6 of each weight. It is comprised with the some motor controller (discrimination means) 47 connected independently to

The control box 45 has a main controller 48 for controlling the whole of the spin winder 1, and the main controller 48 is an inverter through an AC / DC converter 50 connected to a power source 49. The winding motor 4 is driven at a rotation speed determined by the output frequency from the 51. The AC / DC converter is connected to the driver of the driving motor 6 of each weight, and drives each driving motor 6 at a predetermined rotational speed by a predetermined DC power source to be converted. The motor controller 47 of each weight receives a feedback signal from a thread breaking sensor (detection means) 52 which detects a load current of the drive motor 6, and compares this feedback signal (load current) with a set limit value. Then, the thread Y wound on the winding package P is discriminated, and when the thread is broken, a stop signal is output to the driver 46 to stop driving of the driving motor 6.

In addition, each motor controller 47 feeds back the stop signal at the time of thread disconnection to the operation part 54 of the main controller 48, and the main controller 48 which received this stop signal is shown in FIG. The folding device 30 is driven to separate the wound package P from the thread from the winding drum 21. When the thread break is detected, each motor controller 47 may drive the folding device 30.

In addition, as shown in Fig. 5, the limit value set in the motor controller 47 is a load current when the drive motor 6 of each weight is rotated to rotate at a predetermined constant speed which is a predetermined target rotational speed. As a reference value. The load current at this time is a value related to the tension and the like of the yarn Y wound on the winding package P, and the variation is relatively stable at 2 to 3%.

When the thread is broken, the load current for the drive motor 6 is lowered from the reference value, and a certain range below several percent considering the above variation is considered as the limit value.

The motor controller 47 compares the actual load current of the driving motor 6 fed back from the thread break sensor 25 with a limit value, determines that the thread load is broken if the actual load current is below the limit value, and drives the weight. A stop signal is outputted to the driver 46 to stop the driving of the motor 6, and the forward signal is fed back to the main controller 48 again.

This limit value is set from the input board 53 to the motor controller 47 via the main controller 48.

The setting of the limit value, that is, the ratio of the limit value to the load current in the stable region, can be set by the input board 53 at an arbitrary ratio with respect to an arbitrary weight (the driving motor 6). have.

Although the button drive type spin winder 1 is configured as described above, the operation procedure of the spin winder 1 will be described next. When electric power is supplied from the power source 49 to the driver 46 and the main controller 48 of each weight through the converter 50, the driving motor 6 of each weight is driven to the output of the converter 50. The rotary disks 33 of the respective spindle units 2 are rotated at the same rotational speed. And the thread breakage determination by the motor controller 47 is not performed until the rotating disk 33 reaches the rotation speed of a fixed speed. The main controller 48 drives the winding motor 4 at a rotation speed determined by the output frequency from the inverter 51, and outputs the output of the winding motor 4 to each pulley, belt, and reducer 11. ), The continuously variable transmission 17 and the cam box 27 are transmitted to the respective support shafts 18 and 23 and the reciprocating rod 18, and the winding drum 21 and the supply roller 26 of each weight are rotated. In addition, the traverse guide 29 of each weight is traversed.

When the sections 33, 31, 26, and 29 of the devices 2 and 3 are operated, the thread Y released from the sudden package 8 of each weight is tensioned. 32, a predetermined tension is imparted, and is ballooned on the rotating disk 33 that rotates at high speed, and is flammed twice to reach the balun guide 37 to reach the feed roller 26.

The twisted thread Y is traversed by the traverse guide 29 of each weight, and wound up by the winding package P pressed by each winding drum 21.

The traverse angle is corrected by the continuously variable transmission 17 in traversing the seal Y with the traverse guide 29.

In this winding state, the load current to the driving motor 6 rises between the predetermined time T1 from the start of driving as shown in Fig. 5, and when the rotation speed of the rotating disk 33 reaches a constant speed, This results in a constant load current I0.

In addition, when winding of the yarn Y of the sudden feeding package 8 is started, the motor controller 47 of each weight is fed to the actual load current continuously fed from the thread breaking sensor 52 after a predetermined time T1 has elapsed. The threshold value is determined by comparing with and the threshold value.

That is, each motor controller 47 determines that the thread break is not broken when the load current from the thread break sensor 52 is within the limit value, and continues the drive of the drive motor 6. When the load current from the thread break sensor 52 becomes lower than the limit value, it is determined that there is thread break and outputs a stop signal to the driver 46 to stop the driving motor 6.

The motor controller 47 stops the driving motor 6, feeds back the stop signal to the main controller 48, and operates the folding device 30 by the main controller 48. , The winding wound package (P) is broken off the winding drum 21 to stop the winding up.

Thus, in the button-driven spin-winding machine 1, when the drive motor 6 which rotates the spindle apparatus 2 of each weight independently is provided, and wound up the combustible thread Y, the thread ( By detecting the load current of the drive motor 6 which varies depending on the tension of Y) or the like, the presence or absence of thread breakage is determined and the thread breakage is detected between the balun guide 37 and the supply roller 26. It is not necessary to provide a conventional drop wire or the like, and the breakage of the yarn Y can be detected without being limited by the arrangement.

Next, an additionally wound spinner 61 provided with a plurality of steep packages is described with reference to FIG. In Fig. 6, the spin winding machine 61 is a multi-twist machine, in which two steep packages 8 are stacked in two stages on the stop plate 31 of the spindle device 2 of each weight. Has the same configuration as the button driving type shown in Figs.

In order to wind up and wound up the yarn Y released from the yarn feeding package 8 of the weight by the spin winder 61, and to wind up the winding package P, the drive motor 6 of each weight is driven, While rotating the rotating disk 33 at high speed, the winding drum 21 and the supply roller 26 of each weight are rotated to traverse the traverse guide 29.

As a result, the yarn Y released from each of the yarn feeding packages 8 superimposed on the two stages of each weight enters the tensioning device 32 located in the center and is spliced to the rotating disk 33 which rotates at high speed. It burns twice until it reaches the balun guide 37 by it. The combustible thread Y is wound up by the winding package P which is traversed by the feed roller 26 and the traverse guide 29, and pressed against the winding drum 21 of each weight.

In this winding state, the motor controller 47 of each weight compares the set load value with the load current of the drive motor 6 fed back from the thread break sensor 52. At this time, as shown in Fig. 5, in the case of the single yarn break in which one thread of the two sudden yarn packages 8 of each weight is broken, the relatively stable variation of the driving motor 6 is 2 to 3% of the load current. Take into consideration a certain range below.

When the actual load current from the thread break sensor 52 becomes lower than the limit value, the motor controller 47 determines that there is single thread break and outputs a stop signal to the driver 46 to drive the motor 6. To stop.

Then, the motor controller 47 stops the drive motor 6, feeds back the stop signal to the main controller 48, and operates the folding device 30 by the main controller 48, The winding wound package P is broken off from the winding drum 21 to stop the winding up.

In this way, the spin-winding machine 61 is provided with a drive motor 6 for independently rotating the spindle device 2 of each weight, and the yarn Y is wound when the yarn Y and the combusted yarn Y are wound. By detecting the load current of the drive motor 6 which varies depending on the tension of the motor and the like, the presence or absence of single thread breakage is determined. Therefore, the conventional method for detecting thread breakage between the balun guide 37 and the supply roller 26 is performed. It is not necessary to provide a drop wire or the like, and the thread breakage of the thread Y can be detected without being limited by the arrangement.

In particular, by determining the presence or absence of thread breakage by detecting the load current of the drive motor 6 of each weight, it is possible to easily and accurately detect single thread breakage that has been difficult in the past.

In the radiation winding machines (1) and (61) of the present invention, since one or a plurality of sudden-emergency packages 8 are stopped on the stop plate 31 during the combustible winding, it is for driving during winding of a constant speed. When the load current of the motor 6 becomes substantially constant and the load current which is substantially constant falls below the limit value, it is possible to determine simply and quickly by determining the presence or absence of thread breakage.

According to the invention of claim 1 or 2, the thread is broken by providing a drive means for driving the spindle means in each weight, and detecting the load of the drive means that varies depending on the tension of the thread when winding the combustible thread. Since it is possible to discriminate the presence or absence of the thread, it is not necessary to provide a detection means for detecting thread break in the moving path of the wound yarn, and it is possible to detect the thread break without being limited in arrangement.

In particular, as in the invention of claim 2, in the case of weaving and twisting the yarns released from the plurality of yarn yarn packages and winding the wound package, single yarn breaks in which one yarn yarn package is broken can be easily and accurately detected.

In addition, as in the invention of claim 3, since the determination means has a threshold value of the thread breakage discrimination set according to the load of the drive means in which the thread is wound at a constant speed, the number of times without requiring the change of this limit value is required. B and a variety of winding machines having different sizes of the spindle diameter of the spindle means.
