  First, based on FIGS. 1-3, the rough structure of the twist yarn blender 100 in this embodiment is demonstrated.

As shown in FIG. 1, the twist yarn blender 100 includes six spindle yarn units U arranged in parallel on the frame 10. As shown in FIG. 3, the rows of the twist yarn units U are arranged back to back. Yes.
In addition, a winding device R for winding the yarn Y is provided at a position corresponding to the second, fourth and fifth twisting yarn units U counted from one end (the left end in FIG. 1) of the twisting yarn blender 100. As shown in FIG. 3, a yarn joining device G is provided between the twisting unit U and the winding device R corresponding to each other.
Further, as shown in FIGS. 1 and 2, the yarn twisted by the twisting unit set V which is the selected two or three twisting unit U among the plurality of twisting unit U is added to the twisting unit set V. The yarns are combined by a corresponding yarn synthesizing device G and wound by a winding device R at a position corresponding to the yarn synthesizing device G.
The twist yarn blending machine 100 is configured to include a plurality of twist yarn units U, at least one winding device R, and a yarn blending device G.

Here, based on FIG.1 and FIG.2, it demonstrates based on FIG.1 and FIG.2 which combination example of the twist unit U which belongs to the said twist unit unit V, and which winding device R and the combined yarn device G respond | correspond to this twist unit unit V. To do.
That is, the twisting yarn blending machine 100 of the present embodiment can select the number of stitches between 2 and 3 depending on the case, and the twisting unit can be selected based on the selected number of stitches. The combination of the twisting unit U belonging to the set V and the winding device R and the combining device G corresponding to the twisting unit set V are determined as follows.

For example, when three yarns are combined, the first, second, and third twisted yarn units U counted from the one end of the twisted yarn blending machine 100 belong to the same twisted yarn unit set V. The yarn twisted at V is twisted by the first yarn counting device from one end (located at the position corresponding to the second twisting yarn unit U counted from one end) and the winding device R. Will be taken.
Similarly, the 4th, 5th, and 6th twisting yarn units U counted from one end belong to the same twisting yarn unit set V, and the yarn from this twisting yarn unit set V is connected to the third yarn joining device G counted from one end. The yarn is wound and wound by the winding device R.
That is, the yarn twisted by the three consecutively selected twisting units U is combined and wound by the combining device G and the winding device R provided at a position corresponding to the central twisting unit U. Will be taken.

On the other hand, when two yarns are combined, the first and second twisted yarn units U counted from one end belong to the same twisted yarn unit set V, and the yarn twisted by this twisted yarn unit set V is The yarn is wound and wound by the first threading device G and the winding device R counted from one end.
Similarly, the third and fourth twisting unit U counted from one end belong to the same twisting unit set V, and the yarn from this twisting unit set V is wound with the second compounding device G counted from one end. The yarn is wound and wound by the device R.
Further, the 5th and 6th twisting unit U counted from one end belong to the same twisting unit set V, and the yarn from this twisting unit set V is the third combining yarn device G and winding device R counted from one end. Are combined and wound up.

  The twist yarn blender 100 further includes a control device C for controlling the plurality of twist yarn units U and a combination yarn number input means for inputting the number of yarns to be combined into the control device C. A yarn number input device I is provided.

  Next, based on FIG. 3, the structure of the twist unit U is demonstrated in detail.

Each of the twisting units U is provided with an electric motor (spindle driving device) 11 provided on the frame 10, a spindle 12 provided substantially vertically and driven by the electric motor 11, and provided integrally with the spindle 12. The rotating disk 13 is mainly composed of a rotating disk 13 on which a punned yarn package Ps is fixedly mounted.
In other words, the spindle 12 is configured to be individually controllable by the electric motor 11 provided for each twisting unit U, and is configured in a so-called spindle single spindle drive type. According to this spindle single spindle drive type, power consumption and noise can be suppressed compared to a tangential belt drive type in which many spindles are rotated together using a belt or the like.
Each of the electric motors 11 is electrically connected to the control device C (see also FIG. 5) via an appropriate signal line C1, and these electric motors 11 are driven by the control device C. It is configured to be controllable.

  The yarn Y unwound from the yarn package Ps passes through the axis of the spindle 12 from the tensor 14 attached to the yarn package Ps, exits from the rotating disk 13, and forms a balloon yarn 15 around the yarn package Ps. The yarn is converged by the guide 16, wound around the feed roller 20 by the yarn guides 17, 18, and 19, combined with another yarn Y by the combining device G, and wound by the winding device R. The yarn Y unwound from the yarn package Ps is given two twists (for example, S twist) before reaching the balloon guide 16.

Further, a yarn feeler 21 as a yarn breakage detecting means is provided on the way from the balloon guide 16 to the yarn guide 18, and this yarn feeler 21 is connected to the control device C (FIG. 1) via an appropriate signal line C1. 5 is also electrically connected).
The yarn feeler 21 includes a sensor arm 21a and a limit switch 21b. The tip of the sensor arm 21 a is always supported by the yarn Y fed between the yarn guide 17 and the yarn guide 18, and the intermediate portion of the sensor arm 21 a is appropriately coaxial with the axis of the yarn guide 17. The base end of the sensor arm 21a is connected to the limit switch 21b.

When the yarn Y supporting the sensor arm 21a is cut, the sensor arm 21a is rotated downward by its own weight, so that the limit switch 21b is operated, and thus the yarn Y is detected to be broken.
As described above, since the yarn feeler 21 is connected to the control device C, the control device C can monitor the state of the yarn Y in all the twisting units U, that is, the yarn breakage.
Thereby, for example, when a yarn breakage occurs in any one twisting unit U belonging to one twisting yarn unit set V, in other words, when any yarn feeler 21 detects a yarn breakage, the control device C Appropriate processing can be performed.

By the way, the feed roller 20 has a function of reducing the tension of the yarn Y sent out from the yarn package Ps. More specifically, the tension of the yarn Y can be reduced by rotating the feed roller 20 at a peripheral speed faster than the feed speed of the yarn Y sent to the feed roller 20.
The tension of the yarn Y appropriately adjusted by the feed roller 20 is called winding tension, and the yarn Y is wound around the winding device R with this winding tension. On the other hand, the tension of the yarn Y before reaching the feed roller 20 is generally called balloon tension.

The yarn guide 19 is also for adjusting the tension of the yarn Y, and is provided outside the feed roller 20 so as to be slidable in the circumferential direction of the feed roller 20.
Thereby, the winding angle of the yarn Y around the feed roller 20 can be adjusted, and the contact distance between the feed roller 20 and the yarn Y can be adjusted.
That is, the tension of the yarn Y in the feed roller 20 can be adjusted not only by the peripheral speed of the feed roller 20 but also by the magnitude of the contact distance.

  Next, the configuration of the yarn joining device G will be described in more detail.

  As shown in FIG. 2, each of the yarn joining devices G provided at a position corresponding to the winding device R is provided with a first yarn guide (on the yarn yarn frame 37 extending in the longitudinal direction of the twist yarn spinning machine 100). Thread guide) 31 and a second thread guide 32 are provided.

  Hereinafter, for convenience of explanation, the yarn Y fed from the first, second, and third twisting unit U counted from the one end is combined by the first spinning device G and the winding device R counted from the one end. The case where it is wound will be described. For convenience of explanation, the feed roller 20 provided in the twisting unit U and the yarn Y fed from the feed roller 20 are fed in order from the one end to the feed rollers 20a, 20b, 20c, 20d, 20e, and 20f, and the yarn Ya. · Yb · Yc · Yd · Ye · Yf

  The first yarn guide 31 is provided at a position close to the yarn path of the yarn Yb fed from a feed roller (first feed roller) 20b provided at a position corresponding to the winding device R, and at other positions. The yarn path of the yarn Ya fed from the feed roller (second feed roller) 20a provided in the guide roller is guided along the yarn path of the yarn Yb fed from the feed roller 20b.

  The second yarn guide 32 is provided at a position close to the yarn path of the yarn Yb sent out from the feed roller 20b, and is provided on the opposite side of the feed roller 20a with the feed roller 20b interposed therebetween (first roller). (3 feed rollers) 20c has a function of guiding the yarn path of the yarn Yc fed from the feed roller 20c along the yarn path of the yarn Yb fed from the feed roller 20b.

  Further, with respect to the arrangement positions of the two first yarn guides 31 and 32, the first yarn guide 31 and the second yarn guide 32 are provided in this order from the upstream side of the yarn path of the yarn Yb fed from the feed roller 20b. It has been.

The yarn Ya fed from the feed roller 20a is fed to the first yarn guide 31 via a third yarn guide 33 provided as appropriate on the composite yarn frame 37.
Similarly, the yarn Yc sent out from the feed roller 20 c is sent to the second yarn guide 32 via another third yarn guide 33.

  By configuring as described above, the three yarns Ya, Yb, Yc fed from the feed rollers 20a, 20b, 20c are suitably combined by the combining device G, and the combined yarn Y is the combined yarn Y Z will be formed.

In addition, when producing the combined yarn Z which consists of the three yarns Y as described above, the feed rollers 20d, 20e, and 20f and the yarns Yd, Ye, and Yf are fed rollers 20a, 20b, and 20c, and The yarns Yd, Ye, and Yf operate in the same manner as the yarns Ya, Yb, and Yc, and the yarns Yd, Ye, and Yf are combined by the third combining device G counted from the one end as described above.
However, the yarn Yd sent out from the feed roller 20d is sent to the first yarn guide 31 provided in the synthesizing device G via the second yarn guide 32 provided in the second synthesizing device G counted from the one end. It is supposed to be. Further, when the three yarns Y are combined as described above, the second winding device R counted from the one end is not used.

  The above description has been made on the yarn joining device G in the case where the three yarns Y are joined. Next, the yarn joining device G in the case where the two yarns Y are joined together will be described.

Here, the first yarn splicing device G counted from the one end will be described.
The first yarn guide 31 provided in the yarn joining device G guides the yarn path of the yarn Ya along the yarn path of the yarn Yb, as in the case of the above three.
On the other hand, the second yarn guide 32 exerts only a function of suitably guiding the combined yarn Z to a yarn cutter YC described later by slightly contacting the combined yarn Z composed of the yarn Ya and the yarn Yb.

Next, the second spinning device G counted from the one end will be described.
The first yarn guide 31 provided in the yarn joining device G is provided at a position close to the yarn path of the yarn Yd from the feed roller (first feed roller) 20d, and from the feed roller 20c (second feed roller). The yarn path of the yarn Yc is guided along the yarn path of the yarn Yd.
The second thread guide 32 performs only the same function as described above.

Next, the third yarn splicing device G counted from the one end will be described.
The second yarn guide 32 included in the yarn joining device G is provided at a position close to the yarn path of the yarn Ye from the feed roller 20e, and the yarn path of the yarn Yf from the feed roller 20f is connected to the yarn Ye. Guide along the yarn path.
On the other hand, the first yarn guide 31 is not used and is separated in advance in a direction away from the yarn Ye. The point that the first thread guide 31 can be separated (slidable) will be described later.

  As described above, even if the use and function may be slightly different depending on the number of yarns, the components and production lines constituting the yarn synthesizing apparatus G can be obtained by making each of the yarn synthesizing apparatuses G the same as described above. Can be made common, and the manufacturing cost of the spinning device G can be reduced.

By the way, in order for the combined yarn Z to be suitably wound by the winding device R, it is necessary to individually measure and manage the winding tension of each yarn Y before the combined yarn.
Management here refers to, for example, changing the peripheral speed of the feed roller 20 that feeds each yarn Y, or changing the attachment position of the yarn guide 19 based on the measurement result of the winding tension for each yarn Y. The adjustment is made so that the winding tensions of the yarns Y to be combined are uniform.

  Thereafter, the yarn Y sent out from the first, second and third twisting unit U counted from the one end is combined and wound by the first combining device G and the winding device R counted from the one end. The case will be described.

As shown in FIG. 2, a sufficient space for individually measuring the winding tension is secured on the yarn paths of the yarn Ya and the yarn Yc fed from the feed roller 20a and the feed roller 20c.
On the other hand, the yarn path of the yarn Yb from the feed roller 20b is close to the first yarn guide 31 and the yarn path of the yarn Ya immediately after being fed from the feed roller 20b. Therefore, even if the winding tension of the yarn Yb before being combined is to be measured independently, the feed roller 20b, the first yarn guide 31 and the yarn path of the yarn Ya are in the way, and sufficient for the measurement. Space cannot be secured.

  Therefore, the first yarn guide 31 is provided so as to be separated in a direction away from the feed roller 20b. More specifically, the separating direction is a direction of retreating from the yarn path of the yarn Yb fed from the feed roller 20b.

As shown in FIG. 2, a guide hole 31 a for guiding the first yarn guide 31 extends along the retraction direction of the first yarn guide 31.
Hereinafter, the configuration of the first yarn guide 31 will be described with reference to FIG.

  The first yarn guide 31 is provided on the opposite side of the guide portion 31b for guiding the yarn Y, and the guide portion 31b and the combined yarn frame 37, and a part of the first yarn guide 31 is a hollow cylindrical shape that is loosely inserted into the guide hole 31a. Spring accommodating portion 31c, and a coil spring 31d and a screw 31e accommodated together in the spring accommodating portion 31c.

The screw 31e is screwed into the guide portion 31b with the coil spring 31d interposed therebetween, whereby the guide portion 31b is urged toward the combined yarn frame 37.
Further, when the screw 31e is screwed deeply into the guide portion 31b, the first yarn guide 31 can be fixed at one point of the guide hole 31a. On the other hand, when the screw 31e is loosened from the guide portion 31b, the first yarn guide 31 is It becomes possible to slide along the guide hole 31a.

On the left side of FIG. 2, the first yarn guide 31 that is separated from the feed roller 20b along the guide hole 31a in the first yarn joining device G counted from the one end, and changes accordingly. The yarn path of the finished yarn Ya is indicated by a broken line.
Further, on the right side of the drawing in the drawing, a space S formed by the separation of the first yarn guide 31 in the third yarn joining device G counted from the one end is shown.
When measuring the winding tension of the yarn Y, as shown in the portion of the third stitching device G, the measuring instrument is placed on the space S from the side opposite to the direction in which the first yarn guide 31 is retracted. Just plug it into

  As described above, by separating the first yarn guide 31 in the direction away from the feed roller 20b, it is necessary to independently measure the winding tension of the yarn Yb on the yarn path of the yarn Yb. The space S can be secured.

  Further, since the direction in which the first yarn guide 31 is separated is the direction in which the first yarn guide 31 is retracted from the yarn path of the yarn Yb, the yarn path of the yarn Yb and the yarn path of the yarn Ya can be separated, and the space S is more preferably formed. It is like that.

  As described above, the winding tension of each of the three yarns Ya, Yb, Yc can be easily measured and grasped independently. For example, the peripheral speed of the corresponding feed roller 20 can be changed, or the yarn guide can be changed. It is possible to adjust the winding tension of each of the three yarns Y to be uniform by changing the attachment position 19. Thereby, the quality of the winding package produced | generated with the winding apparatus R can be improved.

  Further, since it is not necessary to dispose the first yarn guide 31 away from the feed roller 20b in order to secure a measurement space for measuring the winding tension of the yarn Yb alone, the compactness of the width of the machine base is lost. There is nothing.

Further, since the second yarn guide 32 used when combining three yarns is provided in advance away from the feed roller 20b, the winding of the yarn Yb fed from the feed roller 20b is performed. The space S required for measuring the tension alone is not reduced.
Accordingly, the second yarn guide 32 does not need to be configured to be separated in the direction away from the feed roller 20b, and can be configured simply.

  Note that the direction in which the first yarn guide 31 is separated from the feed roller 20b is also the direction in which the first yarn guide 31 is retracted from the yarn path of the yarn Yb, so the first yarn guide 31 does not interfere with the second yarn guide 32. It can be separated from 20b.

In the above, the method for measuring the winding tension before the yarn Yb is combined when the number of yarns Y to be combined (hereinafter also referred to as the number of combined yarns) is three has been described. Even when the number of combined yarns is two, the above-described useful effects are exhibited.
However, in this case, in the third yarn splicing device G counted from the one end, the first yarn guide 31 is retracted in advance without being used, and the second yarn guide 32 instead passes the yarn path of the yarn Yf. Since the guide is provided along the yarn path of Ye, the winding tension of the yarn Ye can be measured at any time.

  By the way, yarn cutters YC (YC1 to YC3) as yarn cutting means for cutting the yarn Y that is combined and wound up are respectively connected to the yarn paths of the combined yarn Z sent out from the above-described combined yarn device G, and appropriate ones. A pair of fourth yarn guides 35 and a thread guide plate 36 with slits, which are yarn guide means, are provided on the combined yarn frame 37 in this order.

  Each of the plurality of yarn cutters YC provided is electrically connected to the control device C by an appropriate signal line C1 (see FIGS. 3 and 5). Thereby, the control apparatus C can cut | disconnect the thread | yarn Y which comprises the composite yarn Z sent out from the composite yarn apparatus G via the yarn cutter YC as needed.

  Further, the pair of fourth yarn guides 35 and the slitted yarn guide plate 36 suppresses the yarn path of the combined yarn Z from becoming unstable when traversed by a traverse device 40 described later of the winding device R. It is.

Next, the winding device R will be described.
As shown in FIG. 3, the yarn Y is combined by the combining device G, then passed through the yarn cutter YC, and passed to the winding device R via the pair of fourth yarn guides 35 and the thread guide plate 36 with slits. Led.

The combined yarn Z guided to the winding device R is wound as a winding package on the winding bobbin 42 rotating on the winding drum 41 while being traversed by the traverse device 40. The winding bobbin 42 is rotatably supported by a pair of cradle arms 43 that are rotatable around a rotation center 43a via a bobbin holder 43b, and the pair of the cradle is increased with an increase in the winding diameter of the winding package. The arm 43 is configured to freely rotate.
As shown in FIG. 1, each of the winding drums 41 included in the plurality of winding devices R is connected to a drive shaft 41 a that extends and extends across the plurality of winding devices. Are driven simultaneously by a common driving device. In addition, the pair of cradle arms 43 are configured not only to freely rotate as described above, but also to be able to be appropriately rotated by the control device C via a signal line (not shown).

In addition, as shown in FIGS. 1, 3 and 5, in this embodiment, the control device C is electrically connected to the control device C through a signal line C1, and the spindle 12 of the twisting unit U is started to rotate. There are provided a plurality of spindle start switches (spindle start operation means) SS (SS1 to SS3) which are operated in order to achieve this.
More specifically, as shown in FIG. 3, the spindle start switches SS1 to SS3 are alternate switches that can maintain an electrical short circuit / non-short circuit state (that is, an ON state / OFF state). As shown in FIG. 1, one is provided at each position corresponding to the winding device R. That is, the spindle start switches SS1, SS2, and SS3 are arranged so as to have a positional relationship corresponding to each of the first, second, and third winding devices R counted from the one end of the yarn twisting machine 100.

  Next, based on FIG. 1, FIG. 5 and FIG. 6, the control device C and the combined yarn number input device I included in the twisted yarn spinning machine 100 will be described.

As described above, the control device C can control a plurality of twisting units U included in the twisting and spinning machine 100, and as shown in FIG. 5, an arithmetic processing unit 70, a readable / writable memory unit 71, It has.
Further, as shown in FIG. 1, the control device C includes a combined yarn number input device I that can input the number of yarns to be combined into the control device C, and a display panel device that can display characters, numbers, and the like. D and a change button (change setting button) B which is a button for confirming the setting of the number of combined yarns are attached.

As shown in FIG. 5, the arithmetic processing unit 70 can bidirectionally transmit and receive data to and from the memory unit 71, and receives input data from the yarn number input device I via the yarn number input unit 72. It is configured to be able to.
Further, the arithmetic processing unit 70 can transmit the contents to be displayed on the display panel device D via the display panel unit 73, and can individually drive and control each of the electric motors 11 via the motor control unit 74. The state of the yarn Y (occurrence of yarn breakage) corresponding to each of the yarn feelers 21 can be received as a signal via the detection unit 75.
Further, the arithmetic processing unit 70 can detect that the yarn Y can be cut by operating the yarn cutter YC via the yarn cutter unit 76, and the spindle start switch SS has been operated (switched) via the start switch unit 77. The change button B can be detected through the change button input unit 78.

As shown in FIG. 6, the memory unit 71 includes a combination of the twisting unit U belonging to the twisting unit set V, a yarn cutter YC belonging to (associated with) the twisting unit set V, and a spindle start for each number of combined yarns. The switch SS is stored in advance as the combined yarn mode array 80.
The stitching mode array 80 includes a two-spinning mode array 80a (2PLYMODE) that is read when the number of stitches is input as two, and a three-threading mode array 80b (3PLYMODE) that is read when the number of stitches is three. ).

In the above-described two-yarn yarn mode array 80a, three pairs of twisting unit sets V, which are one set of two units, are formed from the plurality of twisting unit U (No. 1 to No. 6). And the combination of the twist unit U is selected so that each of the twist unit U which belongs to the same twist unit unit V may adjoin (continue) (refer also FIG.1 and FIG.2 also).
Further, in this two-yarn yarn mode array 80a, the yarn cutters YC1 to YC3 (see FIG. 2) and the spindle start switches SS1 to SS3 (see FIG. 1) are connected to the twisted yarn unit group V (set number 1, 2, 3). They are stored in association with each other in a one-to-one correspondence.

Similarly, in the three-yarn mode arrangement 80b, the same twisting unit is formed so that two sets of twisting unit sets 1 and 2 are formed from the plurality of twisting units U as one set of three units. The combination of the twist units U is selected so that each of the twist units U belonging to the set V is continuous (see also FIGS. 1 and 2).
Further, in this three-combination yarn mode array 80b, the yarn cutters YC1 and YC3 and the spindle start switches SS1 and SS3 are associated with each of the twisting unit sets V (set numbers 1 and 2) in a one-to-one correspondence. It is remembered.

  Then, the control device C, based on the number of combined yarns input by the combined yarn number input device I, when the change button B is pressed, the above-described two double yarns stored in the memory unit 71 in advance. The mode array 80a or the triple-thread mode array 80b is read into the arithmetic processing unit 70.

This is equivalent to suitably selecting a combination of the twisted yarn units U belonging to the twisted yarn unit set V from the plurality of twisted yarn units U.
Similarly, the control device C corresponds to associating the yarn cutter YC and the spindle start switch SS with the twisting unit set V based on the inputted number of combined yarns.

  As a result, the arithmetic processing unit 70 determines which twist unit U the arbitrary twist unit U belongs to based on the read combination yarn mode array 80, and the same twist unit unit as the arbitrary twist unit U. It is possible to recognize which other twisted yarn unit U belongs to V. And the control apparatus C controls the said some twisting unit U collectively for every said combination. More specifically, drive control of the spindles 12 of the plurality of twisting unit U is collectively performed for each combination.

In addition, when any yarn feeler 21 detects a yarn break, the control device C performs control so that the yarn cutter YC associated with the twist unit U to which the twist unit U in which the yarn break has been detected operates. To do.
Further, when the operation of any of the spindle start switches SS is detected, the control device C starts all the spindles 12 of the twisting unit U belonging to the twisting unit set V associated with the spindle start switch SS. To control. In other words, by appropriately operating one of the spindle start switches SS as will be described later, the controller C recognizes, for example, which twisting unit set V is ready to start winding, and the twisting unit Control is performed so that the twisted yarn units U belonging to the set V are started all at once.

  Further, the winding device R and the yarn synthesizing device G are also associated with the corresponding twisting unit set V via the twisting unit U provided at the corresponding position.

  Next, the operation of the twist yarn blending machine 100 according to the present embodiment will be described with reference to the drawings.

FIG. 7 is a flowchart at the start of operation of the twisting yarn blending machine according to one embodiment of the present invention.
FIG. 8 is a flowchart when the yarn breakage occurs in the twisting yarn blending machine according to the embodiment of the present invention.
FIG. 9 is a flowchart when restarting the operation of the twisting yarn blending machine according to the embodiment of the present invention.
FIG. 10 is a flowchart when changing the number of combined yarns of the twisting yarn blending machine according to the embodiment of the present invention.

  First, based on FIG. 7, the operation start time of the twisting yarn blender 100 of the present embodiment will be described.

On the display panel device D, a message for prompting input of the number of combined yarns is displayed in advance.
First, the worker inputs the number of combined yarns to the control device C via the combined yarn number input device I, and depresses the change button B (S301). Then, based on the input number of combined yarns, the corresponding combined yarn mode array 80 (two-thread-connected yarn mode array 80a or three-thread-connected yarn mode array 80b shown in FIG. 6) is calculated from the memory unit 71. It is automatically read into the unit 70.
This corresponds to the fact that the control device C has selected the combination of the twisting unit U belonging to the twisting unit set V from the plurality of twisting units U as described above. Thereby, the control apparatus C can drive-control the spindles 12 of the plurality of twisting unit U for each combination.

Next, an operator attaches the yarn package Ps to the rotary disk 13 provided in each of the twisting unit U, and attaches an empty winding bobbin 42 to the pair of cradle arms 43 (S302). (See also 3).
At this time, as indicated by a two-dot chain line in FIG. 3, the empty winding bobbin 42 is separated from the winding drum 41 that is constantly rotating (floating), and the rotation is stationary. Thus, the pair of cradle arms 43 is held in a state of being slightly rotated upward (in this way, the winding bobbin 42 and a winding package / full winding package described later are separated from the winding drum 41. (The state is also referred to as a cradle-up state of the winding device R.)

  Hereinafter, a case where three yarns Y are combined, that is, a case where the three-thread mode array 80b is read into the arithmetic processing unit 70 will be described.

  First, the worker draws the yarn Y (for example, the yarns Ya to Yc, see FIG. 2) from each of the twisted yarn units U belonging to the same twisted yarn unit set V based on the inputted number of combined yarns (3), These yarns Y are passed through a spinning device G (for example, the first counting from the one end, see FIG. 2) corresponding to the twisting unit set V, and mounted on a winding bobbin 42 provided in the corresponding winding device R. (S303) (see also FIG. 2).

  However, at the start of operation of the twisting yarn threading machine 100 of the present embodiment, an operation for inputting the number of yarns to be combined (S301), an operation for mounting the yarn package Ps / winding bobbin 42 (S302), and threading / threading. These operations (S303) are out of order.

  The operation of pulling out the yarn Y and attaching it to the take-up bobbin 42 may be performed for each twisted yarn unit set V or may be performed simultaneously for all the twisted unit sets V. In other words, the winding may be started sequentially from the twisted yarn unit group V after the above work is completed, or after all the twisted yarn unit groups V are finished, the winding is started all at once. Good.

When the operator switches the spindle start switch SS that is provided at a position corresponding to the winding device R and is in an OFF state in advance to an ON state (S304), which spindle start switch SS is The control device C detects whether the state has been switched to the ON state. In other words, by switching the spindle start switch SS associated with an arbitrary twisting unit set V to the ON state, the control device C can detect that the preparation for starting winding is completed in the twisting unit set V. It has become.
In addition, the operation | movement after this is implemented for every twist unit unit V except the case where the number of combined yarns is changed.

  The arithmetic processing unit 70 recognizes the twist unit unit V associated with the spindle start switch SS switched to the ON state based on the read three-unit yarn mode array 80b. By recognizing the twisting unit U to which it belongs, all the rotations of the spindles 12 provided in each twisting unit U are simultaneously started.

  At the same time, in the winding device R corresponding to the twisting unit set V, the control device C lowers the cradle arm 43 so that the winding bobbin 42 contacts the winding drum 41 that is always rotating. The winding bobbin 42 starts to rotate in the direction of the arrow shown in FIG. 3 (the winding drum 41 and the winding package / full winding package are in contact with the winding drum 41 and are rotating. Also referred to as the cradle down state of the device R).

  Thereby, the yarn Y is twisted in each twisted yarn unit U belonging to the twisted yarn unit set V, and the yarn Y drawn from the other twisted yarn unit U belonging to the same twisted yarn unit set V is combined in the yarn twisting device G. Further, the winding device R starts to be wound around the winding bobbin 42 as a winding package (S305).

This is the end of the description regarding the start of operation of the twisted yarn blender 100 of the present embodiment.
The fully wound package formed by winding the combined yarn Z by the winding bobbin 42 is appropriately collected by an operator.

Before starting the winding described above, it is preferable to adjust the winding tension of each yarn Y in advance as shown in FIG.
When it is desired to measure the winding tension of the yarn Yb (or the yarn Ye) alone, the first yarn guide 31 may be separated in the direction away from the feed roller 20b.
Further, when the first thread guide 31 is separated as described above, it is only necessary to slightly loosen the screw 31e shown in FIG. Thereby, the first yarn guide 31 can slide along the guide hole 31a.

  As a result, a suitable space S as shown on the right side of FIG. 2 is formed on the yarn path of the yarn Yb, and the winding tension of the yarn Yb can be measured independently.

  Next, based on FIG. 8, the operation | movement at the time of the yarn breakage generation | occurrence | production of the twist yarn blender 100 of this embodiment is demonstrated.

  When yarn breakage occurs in any of the twisting unit U provided in the twisting yarn blending machine 100 of the present embodiment (S401), the yarn breakage is detected by the yarn feeler 21 provided in the twisting yarn unit U. And the control apparatus C detects the unit number shown, for example in FIG. 6 of the said twist unit U via this yarn feeler 21. FIG.

Then, the arithmetic processing unit 70 (the control device C) recognizes which twist unit U belongs to which twist unit U to which the twist unit U belongs based on the three-yarn mode arrangement 80b (S402). The corresponding yarn cutter YC is operated to cut all the yarns Y of the other twisting unit U belonging to the same twisting unit set V (S403).
Further, all the spindles 12 included in each of the twisting unit U belonging to the twisting unit set V are stopped (S404).
Furthermore, the winding device R corresponding to the twisted yarn unit set V is placed in the cradle-up state, whereby the winding package stops rotating (S405).

As described above, it is possible to prevent the yarn Y from being wound around the winding device R by single yarn winding, that is, an unintended number.
Further, only by inputting the number of combined yarns through the combined yarn number input device I, the process for preventing the single yarn winding is performed only in the twisted yarn unit set V in which the yarn breakage has occurred. Conventionally, when changing the number of combined yarns, it has been necessary to replace a drop wire (a yarn breaker feeler) with a member that interferes with a balloon of another twisted unit in accordance with the number of combined yarns. However, the above configuration eliminates the necessity and makes it easy to change the number of combined yarns.
Moreover, since the process for preventing the single yarn winding is performed only in the twisted yarn unit set V in which the yarn breakage occurs, the winding of the combined yarn Z can be continued in the other twisted yarn unit sets V. It can be done. Thereby, the fall of the production efficiency of a winding package by generation | occurrence | production of a thread break can be suppressed.
Further, the cradle arm 43 of the winding device R is rotated up and down appropriately for each winding device R at the start of winding or when winding is stopped, that is, between the cradle up state and the cradle down state as appropriate. Since it is configured to be switchable, it is not necessary to stop the rotation of the common drive shaft 41a that drives the winding drum 41. In this sense as well, the winding of the combined yarn Z is performed in the other twisted yarn unit sets V. Can be continued.

  Further, when the corresponding spindle 12 is stopped, it is possible to prevent the cut yarn Y from becoming entangled in another twisted yarn unit U and the yarn package Ps supplying the yarn Y from being loosened. Furthermore, by stopping the rotation of the winding bobbin 42, the cut yarn Y can be easily joined.

This is the end of the description of the operation when the yarn breakage occurs.
The display panel device D preferably displays the twisted yarn unit set V in a stopped state, the twisted yarn unit U belonging to the twisted yarn unit set V, and the like. More specifically, for example, the group number of the twisted yarn unit group V shown in FIG. 6 and the unit number of the twisted yarn unit U may be displayed on the display panel device D.
The winding in the twisted yarn unit group V in which the yarn breakage has occurred can be resumed individually without any interference with the other twisted unit unit V, as will be described below.

  Hereinafter, based on FIG. 9, the operation | movement at the time of the driving | operation restart of the twisting yarn blender 100 of this embodiment is demonstrated.

  First, an operator pulls out the yarn Y from each of the twisted yarn units U belonging to the twisted yarn unit set V in which the yarn breakage has occurred (resumption of operation), and sends the yarn Y to the yarn joining device G corresponding to the twisted yarn unit set V. The thread Y is threaded (threading operation), and the thread Z is joined with the thread Y of the winding package of the corresponding winding device R (S501) (see also FIG. 2).

  Next, the worker turns the spindle start switch SS corresponding to the twisted yarn unit set V to the OFF state and then switches it to the ON state (S502). Then, similarly to the operation at the start of the operation described above, the control device C recognizes the corresponding twisting unit U based on the three-yarn mode arrangement 80b, and starts the rotation of the spindle 12 included in each twisting unit U. Then, the winding device R corresponding to the twisted yarn unit set V is brought into the cradle down state.

  As a result, in the twisted yarn unit set V, the yarn Y is twisted and combined, and the winding in the winding device R is resumed (S503).

The operation related to the resumption of operation is as described above.
Here, as described above, in the twist yarn blending machine 100 according to the present embodiment, each twist unit unit V can be controlled individually. That is, for each twisted yarn unit group V, winding of the yarn Y to be combined can be started or resumed as soon as preparation is completed. In other words, winding can be started or restarted in order from the twisted yarn unit group V ready for winding.
Therefore, it is possible to minimize a decrease in the production efficiency of the winding package. In other words, the production efficiency can be improved.

Even if the number of combined yarns is changed, the operator can start the twisting unit U belonging to the twisting unit set V by operating the spindle start switch SS in the same manner as before the change.
Further, since the spindle start switch SS associated with the twisting unit group V is arranged at a position corresponding to the twisting unit set V, the worker who has finished the threading / threading operation on the spot can perform the above winding operation. Can be started or resumed immediately.
As a result, the workability of the worker is improved, and in this sense, the production efficiency of the winding package can be improved.
Note that the operation resuming operation of the twisted yarn blending machine 100 of the present embodiment described above is not limited to the case where the yarn breakage occurs, and can be applied, for example, when the operation is resumed after the maintenance of the twisting unit U.

  Incidentally, when it is desired to change the number of combined yarns, first, as shown in FIG. 10, an operator inputs the number of combined yarns anew (S601). Next, the worker presses the change button B attached to the control device C. Thereby, based on the said number of combined yarns, the combined yarn mode arrangement | sequence 80 is read, and the combination of the twist unit U which belongs to the twist unit unit V is selected suitably. The threading / threading operation (S602), the operation of operating the spindle start switch SS (S603), and the like are the same as the operations at the start of the operation described above. Then, the twisting / synthesizing / winding is resumed (S604).

  In this way, the combination of the spindles 12 to be simultaneously driven and controlled based on the number of combined yarns can be changed simply by inputting the number of yarns via the combined yarn number input device I. Good workability. Therefore, the production efficiency of the winding package can be improved.

Further, as described above, in this embodiment, an alternate type switch is used as the spindle start switch SS (spindle start operation means).
As a result, the operator can visually determine the state (ON state or OFF state) of the spindle start switch SS, so that human errors can be suppressed compared to when a momentary switch is used. Can do.
In addition, in order to resume the twisting / combining of the yarn Y and the winding in the winding device R in any twisting unit set V, the spindle start switch SS is once turned off and then turned on again. A two-stage operation is imposed on the worker, and in this sense as well, the artificial erroneous operation can be suppressed as described above.
Furthermore, an arbitrary operation of the control device C can be assigned to the operation of switching the spindle start switch SS to the OFF state.
For example, when one of the spindle start switches SS is switched to the OFF state, the control device C recognizes the corresponding twisting unit U based on the three-yarn mode arrangement 80b, and the spindle 12 included in each twisting unit U The rotation can be stopped and the winding device R corresponding to the twisting unit set V can be controlled to be in the cradle-up state.
As a result, even when maintenance of the electric motor 11, the spindle 12, or the respective yarn guides becomes necessary, it is not necessary to stop the operation of the entire twisting and spinning machine 100, and the twisting unit group including a device that simply requires maintenance. Since only V needs to be stopped, it is possible to suppress a reduction in the production efficiency of the winding package.
