Special table 2001-500576

  In recent years, from the viewpoint of increasing productivity in a combined yarn false twisting machine, it is required to increase the number of packages formed by the combined yarn false twisting machine. In order to increase the number of packages formed by the combined yarn false twisting machine, it is necessary to increase the number of false twist spindles and the like. On the other hand, in the combined yarn false twisting machine described in Patent Document 1, false twist spindles are arranged in a row in the machine table longitudinal direction. Therefore, in the combined yarn false twisting machine described in Patent Document 1, the length in the machine table longitudinal direction of the space necessary for arranging the false twist spindle becomes long.

  Here, it is conceivable that the false twisting spindles are shifted from each other when viewed from the longitudinal direction of the machine base, and the false twisting spindles that are shifted from each other are arranged in the longitudinal direction of the machine base. However, even in this case, as will be described later, when the yarn is crossed between the false twist spindle and the mixing nozzle, the false twist spindles cannot be packed so much in the longitudinal direction of the machine base. Moreover, in the combined yarn false twisting machine as described in Patent Document 1, it is usually long in the machine table longitudinal direction. For these reasons, in the combined yarn false twisting machine described in Patent Document 1, when the number of false twisting spindles is increased, the combined yarn false twisting machine is greatly enlarged in the longitudinal direction of the machine base.

  An object of the present invention is to provide a combined false false twisting machine capable of combining different types of yarns and suppressing the increase in size in the machine table longitudinal direction as much as possible.

  The combined false false twisting machine according to the first aspect of the invention is characterized in that false twisting is performed on a plurality of yarns, and a plurality of yarns subjected to false twisting are combined two by two, which is long in the machine table longitudinal direction. It is a combined yarn false twisting machine, and a plurality of false twists that supply a plurality of yarns, and a plurality of false twists that are arranged in the longitudinal direction of the machine base and perform false twisting on the plurality of yarns supplied from the yarn feeding part A plurality of yarn joining devices that respectively join two yarns out of a plurality of yarns arranged in the machine unit longitudinal direction and false twisted in the plurality of false twisting portions; A plurality of winding devices for winding the yarns combined with each other, each false twisting unit is more than a first heating unit for heating two yarns, and the first heating unit A second heating unit that is disposed on one side in the longitudinal direction of the machine base and that heats two yarns different from the first heating unit, and two yarns heated by the first heating unit A first cooling section to be rejected, and a second cooling section that is displaced from the first cooling section to the one side in the longitudinal direction of the machine base and cools two yarns heated by the second heating section And two first twisting devices that impart twist to the two yarns cooled by the first cooling unit, and two first twisting devices that impart twist to the two yarns cooled by the second cooling unit. A yarn twisted by the first twisting device on the other side in the machine longitudinal direction of the two first twisting devices. Of the two second twisting devices, a first stitching device for stitching yarns twisted by the second twisting device on the other side in the machine table longitudinal direction, and the two Among the first twisting devices, the yarn that has been twisted by the first twisting device on the one side in the machine longitudinal direction, and the two second twisting devices A first yarn twisting device, and a second yarn twisting device for joining the yarns twisted by the second twisting device on the one side in the machine table longitudinal direction, and the two first twisting devices, The two second twisting devices are arranged so as not to overlap each other when viewed from the longitudinal direction of the machine base, and in the longitudinal direction of the machine base, the first twisting device and the second twisting device It arrange | positions so that a twist apparatus may be located alternately.

  According to the present invention, one of two yarns heated by the first heating unit and cooled by the first cooling unit, and two yarns heated by the second heating unit and cooled by the second cooling unit One of the yarns is combined in each of the first and second combining devices. Therefore, if the heating conditions of the yarn are different between the first heating unit and the second heating unit, different types of yarns are heated to an appropriate temperature according to the type of yarn and subjected to false twisting. Can be combined.

  Here, in the first and second yarn blending devices, one yarn twisted by the first twisting device and one yarn twisted by the second twisting device are combined. For this purpose, one of the two yarns cooled by the first cooling unit and one yarn of the two yarns cooled by the second cooling unit are subjected to the first and second heating. It is necessary to intersect at any position between the section and the first and second synthesizing devices. In the present invention, the first twisting device and the second twisting device are shifted so as not to overlap each other when viewed from the longitudinal direction of the machine base, and the first twisting apparatus and the second twisting device are arranged in the longitudinal direction of the machine base. And are positioned alternately. Thereby, the yarn intersects at a position between the first and second heating units and the first and second twisting devices on the yarn path. In this case, as will be described later, the first and second additional twisting are performed in comparison with the case where the yarns are crossed at the position between the first and second twisting apparatuses and the first and second combined threading apparatuses. Twisting devices can be arranged with high density in the machine longitudinal direction. As a result, it is possible to suppress as much as possible the enlargement of the combined false false twisting machine long in the machine table longitudinal direction in the machine table longitudinal direction.

  The combined false false twisting machine according to the second invention is the combined false false twisting machine according to the first invention, wherein the first cooling part and the second cooling part are for two yarns to be cooled. The two cooling devices are provided separately and are arranged in the longitudinal direction of the machine base, and the two cooling devices extend so as to be separated in the longitudinal direction of the machine base toward the downstream side of the yarn path.

  According to the present invention, it is possible to reduce the bending of the yarn from the heating unit to the twisting device via the cooling unit, compared to the case where the two twisting devices extend in parallel with each other. Here, in order to perform false twisting on the yarn, it is necessary to propagate the twist imparted to the yarn by the heating device to the upstream portion of the yarn path of the yarn. In the present invention, as described above, the yarn bending from the heating unit through the cooling unit to the twisting device is small, so that the twist propagation can be prevented from being hindered by the yarn bending.

  The combined yarn false twisting machine according to a third aspect is the combined yarn false twisting machine according to the second aspect, wherein the first cooling part and the second cooling part are viewed from the longitudinal direction of the machine base. Out of the two cooling devices that are arranged so as not to overlap each other and constitute the first cooling unit, the cooling device on the one side in the longitudinal direction of the machine base and the second cooling unit Of the two cooling devices, the cooling device on the other side in the machine table longitudinal direction intersects.

  According to the present invention, the first and second cooling units are arranged in the first and second cooling units as compared to the case where the cooling device on one side of the first cooling unit and the cooling device on the other side of the second cooling unit are arranged apart from each other in the longitudinal direction of the machine base. It can be arranged with high density in the machine table longitudinal direction. Thereby, the enlargement to the machine table longitudinal direction of the long yarn twisting machine in the machine table longitudinal direction can be suppressed as much as possible.

  The combined false false twisting machine according to a fourth invention is the combined false false twisting machine according to the second or third invention, wherein the angle formed by the two cooling devices constituting the first cooling unit, and The angle formed by the two cooling devices constituting the second cooling unit is 10 ° or less.

  If the angle formed by the two cooling devices constituting the first and second cooling units is too large, for example, the yarn bends largely on the upstream side of the cooling device on the yarn path. As a result, the twist propagation may be hindered by the bending of the yarn. In the present invention, since the angle formed by the two cooling devices constituting the first and second cooling units is as small as 10 ° or less, the bending of the yarn is reduced. Thereby, it is possible to prevent the propagation of the twist from being hindered by the bending of the yarn.

  According to a fifth aspect of the present invention, in the combined false false twisting machine according to any one of the second to fourth inventions, the two cooling devices constituting the first cooling section are yarns. The two cooling devices constituting the second cooling part are connected and integrated with each other at the upstream end of the yarn path, and are integrated with each other at the upstream end of the yarn path.

  When the two cooling devices of the first and second heating units are separated, for example, when the cooling device is attached to a frame or the like when assembling the combined yarn false twisting machine, the cooling device removed for maintenance is used as a frame. When attaching to the above, it is necessary to adjust the angle between the two cooling devices, and the work becomes complicated. And since the combined yarn false twist processing machine is equipped with many cooling parts, it will become a big burden for an operator to perform such a complicated operation | work about each cooling part. In the present invention, since the two cooling devices are connected and integrated with each other at the end portion on the heating unit side, the angle adjustment between the two cooling devices is performed when the cooling device is attached to a frame or the like. There is no need, and work becomes easy.

  According to the present invention, different types of yarn can be combined with each other after being heated to an appropriate temperature according to the type of yarn and subjected to false twisting. Moreover, the enlargement to the machine table longitudinal direction of the combined yarn false twisting machine long in the machine table longitudinal direction can be suppressed as much as possible.

It is a figure which shows the yarn path | route of the thread | yarn in a combined false false twisting machine. (A) is sectional drawing which shows the cross section orthogonal to the running direction of the thread | yarn of two adjacent primary heating units, (b) is the (alpha) -alpha sectional view taken on the line of (a).

It is a figure equivalent to FIG. 2 which shows an example in the case of making a thread | yarn cross between a twisting apparatus and a combined yarn apparatus different from this invention. FIG. 6 is a view corresponding to FIG. 2, showing an example different from FIG. 5, in the case where the yarn is crossed between the twisting device and the yarn joining device, which is different from the present invention.

  Hereinafter, preferred embodiments of the present invention will be described.

  As shown in FIGS. 1 and 2, the false yarn twisting machine 1 according to the present embodiment includes each device (a primary feed roller 19 and primary heating units 21 a and 21 b described later) that constitute a yarn processing unit 12 described later. , Twisting guide 22, cooling units 23a, 23b, twisting devices 24a, 24b, tension sensor 30, secondary feed rollers 25a, 25b, spinning devices 26a, 26b, secondary heating unit 27, tertiary feed roller 28, etc.) However, the horizontal machine table longitudinal direction (FIG. 1) is perpendicular to the yarn traveling surface (paper surface of FIG. 1) on which the yarn path from the creel stand 11 through the yarn processing unit 12 to the winding unit 13 is arranged. A plurality of devices that are arranged in a direction perpendicular to the paper surface and are long in the machine table longitudinal direction. In the following, the horizontal direction (horizontal direction in FIG. 1) perpendicular to the longitudinal direction of the machine base is defined as “machine width direction”, and the direction in which gravity acts (vertical direction in FIG. 1) is defined as the vertical direction. Give an explanation. Further, the near side and the far side in the direction orthogonal to the paper surface of FIG. 1 are defined as “front side” and “back side” in the longitudinal direction of the machine base, respectively, and the upper side and the lower side in FIG. The description will be made by defining “upper side” and “lower side”. Further, in the combined yarn false twisting machine 1, the creel stand 11, the yarn processing part 12, and the winding part 13 are arranged symmetrically in the machine width direction so that the creel stand 11 side is outside. Further, the operation of the combined false false twisting machine 1 is controlled by the control device 10.

  The creel stand 11 includes a plurality of creels 11a. Each of the plurality of creels 11a holds the yarn supply package S.

  The yarn processing unit 12 includes a primary feed roller 19, primary heating units 21a and 21b, cooling units 23a and 23b, twisting devices 24a and 24b, a tension sensor 30, secondary feed rollers 25a and 25b, and spinning devices 26a and 26b. A secondary heating unit 27, a tertiary feed roller 28, and the like are provided.

  A plurality of primary feed rollers 19 are individually provided for the plurality of yarns Y supplied from the yarn supply package S, and are arranged in the machine table longitudinal direction. The primary feed roller 19 conveys the corresponding yarn Y toward the primary heating units 21a and 21b.

  The primary heating unit 21a (the “first heating unit” of the present invention) and the primary heating unit 21b (the “second heating unit” of the present invention) are disposed on the downstream side of the primary feed roller 19 in the yarn path of the yarn Y. Has been. A plurality of primary heating units 21a and 21b are provided. Each of the primary heating units 21 a and 21 b corresponds to two yarns Y among the plurality of yarns Y supplied from the creel stand 11. The primary heating unit 21a and the primary heating unit 21b are alternately arranged in a line in the longitudinal direction of the machine base. As shown in FIGS. 3A and 3B, the primary heating units 21 a and 21 b include a box 31, a heating block 32, a heater 33, and a temperature sensor 34.

  The box 31 is a rectangular parallelepiped member whose longitudinal direction is the machine width direction. Inside the box 31, an accommodation space 31a that is open at the lower end and both ends in the machine width direction is formed. The heating block 32 is a rectangular parallelepiped member made of a metal material and having the machine width direction as a longitudinal direction, and is accommodated in the accommodation space 31a. The heating block 32 is formed with two yarn traveling spaces 35 for traveling the yarn Y. The two yarn traveling spaces 35 are arranged at an interval in the machine table longitudinal direction. Each yarn traveling space 35 extends over the entire length of the heating block 32 in the machine width direction, and is open at both ends in the machine width direction. The heating block 32 is formed with two slits 36 for introducing yarns into the two yarn traveling spaces 35. The slit 36 extends over the entire length of the heating block 32 in the machine width direction, and is open at both ends in the machine width direction. The slit 36 communicates with the corresponding yarn traveling space 35 at the upper end and opens at the lower end. Thereby, the yarn Y can be introduced into the yarn traveling space 35 from below through the slit 36.

  Further, a portion of the heating block 32 located between the two yarn traveling spaces 35 in the machine table longitudinal direction extends over the entire length of the heating block 32 in the machine table width direction and opens at both ends in the machine table width direction. An insertion hole 37 for inserting the heater 33 is formed. In addition, a concave portion 38 for accommodating the temperature sensor 34 is formed at the center of the upper surface of the heating block 32 in the machine table longitudinal direction and the machine table width direction.

  Here, the heating block 32 is formed by joining four block pieces 32a to 32d arranged in the longitudinal direction of the machine base. The two yarn traveling spaces 35 and the two slits 36 are respectively formed in a portion of the heating block 32 that spans the block pieces 32a and 32b and a portion that spans the block pieces 32c and 32d. . Further, the insertion hole 37 and the recess 38 are formed in a portion of the heating block 32 that spans the block piece 32b and the block piece 32c.

  The heater 33 is a nichrome wire heater, a sheathed heater, or the like, and is inserted through the insertion hole 37. The heater 33 is pulled out from the insertion hole 37 to both sides in the machine width direction and is connected to the current application circuit 29.

  The current application circuit 29 is a circuit for causing a current to flow through the heater 33. When a current is supplied to the heater 33 by the current applying circuit 29, the heater 33 generates heat and the heating block 32 is heated. The yarn Y traveling in the yarn traveling space 35 is heated by the heat of the heating block 32. Here, the current application circuit 29 can individually change the current flowing through the heater 33 of the primary heating unit 21a and the current flowing through the heater 33 of the primary heating unit 21b.

  The temperature sensor 34 is accommodated in the recess 38 of the heating block 32. The temperature sensor 34 is for detecting the temperature of the heating block 32.

  The current application circuit 29 and the temperature sensor 34 are connected to the control device 10. The control device 10 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random access Memory), and the like. The control device 10 controls the current application circuit 29 based on the temperature of the heating block 32 detected by the temperature sensor 34, whereby the current flowing through the heater 33 of the primary heating unit 21a and the heater 33 of the primary heating unit 21b flow. Control the current separately.

  If it demonstrates in detail about control of the control apparatus 10, the control apparatus 10 has previously memorize | stored the information of the preset temperature of the heating block 32 about the primary heating units 21a and 21b in RAM. For example, when the user operates an operation unit (not shown) of the false yarn twisting machine 1 and selects the type of the yarn Y for the primary heating units 21a and 21b, the selected yarn is stored in the RAM of the control device 10 or the like. Information on the set temperature corresponding to the type of Y is stored. When the temperature of the heating block 32 detected by the temperature sensor 34 is lower than the set temperature, the current application circuit 29 is controlled so as to increase the current flowing through the heater 33. On the other hand, when the temperature of the heating block 32 detected by the temperature sensor 34 is higher than the set temperature, the current application circuit 29 is controlled so as to decrease the current flowing through the heater 33. Thereby, the heating block 32 is maintained at the set temperature.

  And if the electric current which flows into the heater 33 is individually controlled by the primary heating unit 21a and the primary heating unit 21b in this way, the primary heating unit 21a and the primary heating unit 21b according to the type of the yarn Y, etc. Thus, the heating temperature of the yarn Y can be varied. For example, when the yarn Y heated in the primary heating unit 21a is a cationic dyeable polyester yarn (CD yarn) and the yarn Y heated in the primary heating unit 21b is a polyester yarn, the heating block of the primary heating unit 21a The temperature of 32 is made higher than the temperature of the heating block 32 of the primary heating unit 21b. As a result, the amount of heat applied to the cationic dyeable polyester yarn and the polyester yarn can be heated to appropriate temperatures.

  Further, a twisting guide 22 is disposed immediately upstream of the primary heating units 21a and 21b in the yarn path of the yarn Y. The twisting guide 22 is to prevent the twist from being propagated upstream of the twisting guide 22 when the yarn Y is twisted as described later.

  The cooling unit 23a (the “first cooling unit” of the present invention) and the cooling unit 23b (the “second cooling unit” of the present invention) are arranged on the downstream side of the primary heating units 21a and 21b in the yarn path of the yarn Y. ing. A plurality of cooling units 23a are provided corresponding to each primary heating unit 21a, and a plurality of cooling units 23b are provided corresponding to each primary heating unit 21b. These cooling units 23a and cooling units 23b are alternately arranged in the machine table longitudinal direction.

  The cooling rejection unit 23a includes two cooling devices 41a and 42a. The cooling unit 23b includes two cooling devices 41b and 42b. The cooling devices 41a, 42a, 41b, and 42b are, for example, a metal material or a ceramic material that forms a gap for running the yarn Y so as to face each other as described in Japanese Patent Application Laid-Open No. 2011-047074. A pair of plate-like members composed of, for example, a duct for communicating with the gap and sucking the air in the gap to generate an air flow in the gap. The yarn traveling in this gap is cooled by the air flowing through this gap. Alternatively, the cooling members 41a, 42a, 41b, and 42b include a pair of plate-like members made of a metal material, a ceramic material, or the like, as described above, and the yarn that travels through the gap contacts the plate-like member. It may be cooled by doing so.

  Moreover, as shown in FIG. 4, the cooling devices 41a and 42a are connected and integrated with each other at the outer end in the machine width direction (upstream side of the yarn path), and are substantially V-shaped. Yes. Thereby, the cooling devices 41a and 42a are separated in the machine table longitudinal direction as they go to the downstream side of the yarn path. Further, the angle θa formed between the cooling device 41a and the cooling device 42a is 10 ° or less (for example, about 5 °). Similarly, the cooling devices 41b and 42b are connected and integrated with each other at the outer end in the machine width direction (upstream side of the yarn path), and are substantially V-shaped. Thereby, the cooling devices 41a and 42a are separated in the machine table longitudinal direction as they go to the downstream side of the yarn path. Further, the angle θb formed between the cooling device 41b and the cooling device 42b is 10 ° or less (for example, about 5 °).

  Here, in the combined yarn false twisting machine 1, for example, when the cooling device 41a, 42a, 41b, 42b is removed for assembly or maintenance of the combined yarn false twisting machine 1, the cooling device 41a , 42a, 41b, 42b need to be attached to the frame of the false false twisting machine 1. At this time, unlike the present embodiment, if the cooling devices 41a and 42a and the cooling devices 41b and 42b are not integrated, the angles θa and θb are set when the cooling devices 41a, 42a, 41b, and 42b are attached. It is necessary to attach the cooling devices 41a, 42a, 41b, and 42b while adjusting the angle between the cooling devices 41a and 42a and the cooling devices 41b and 42b so that the angles are as described above, and the work is complicated. It will be a thing. Furthermore, since the combined yarn false twisting machine 1 includes a large number of cooling units 23a and 23b, the work of attaching the cooling devices 41a, 42a, 41b and 42b in each cooling unit 23a and 23b becomes complicated. The burden on the person will be enormous.

  In contrast, in the present embodiment, as described above, the cooling devices 41a and 42a and the cooling devices 41b and 42b are connected and integrated. Therefore, when the cooling devices 41a, 42a, 41b, and 42b are attached to a frame or the like, it is not necessary to adjust the angle between the cooling devices 41a and 42a and the cooling devices 41b and 42b, and the work can be simplified.

  Further, the cooling unit 23a and the cooling unit 23b are arranged so as to be shifted from each other when viewed from the longitudinal direction of the machine base. As shown in FIG. 4, the cooling device 42a of the cooling unit 23a and the cooling device 41b of the cooling unit 23b intersect each other. Therefore, it is possible to arrange the cooling units 23a and 23b at a higher density in the machine table longitudinal direction than in the case where the cooling units 23a and 23b are arranged in the machine table longitudinal direction apart from the cooling device 42a and the cooling device 41b. it can. Thereby, the enlargement to the machine table longitudinal direction of the combined yarn false twist processing machine 1 in a machine table longitudinal direction can be suppressed.

  The twisting devices 24a and 24b are known belt-type or disk-type twisting devices (see, for example, Japanese Patent Application Laid-Open No. 2007-297774), and are disposed on the inner side in the machine width direction than the cooling units 23a and 23b. ing. One twisting device 24a, 24b is provided for each cooling device 41a, 42a, 41b, 42b of the cooling unit 23a, 23b. The plurality of twisting devices 24a and the plurality of twisting devices 24b are each arranged in the machine table longitudinal direction. Here, the spacing between the twisting devices 24a and the spacing between the twisting devices 24b in the machine table longitudinal direction are larger than the spacing between the two yarn traveling spaces 35 in the primary heating units 21a and 21b. Furthermore, the twisting device 24a and the twisting device 24b are arranged so as to be shifted so as not to overlap each other when viewed from the longitudinal direction of the machine base. In addition, the twisting device 24a and the twisting device 24b are alternately positioned in the machine table longitudinal direction.

  The twisting device 24a (the “first twisting device” of the present invention) twists the yarn Y heated by the primary heating unit 21a and cooled by the cooling unit 23a. The twisting device 24b ("second twisting device" of the present invention) applies twist to the yarn Y heated by the heating unit 21b and cooled by the cooling unit 23a. At this time, in the yarn Y, twist is applied to a portion between the twisting guide 22 and the twisting devices 24a and 24b. At this time, the yarn Y is twisted while being heated in the primary heating units 21a and 21b, and the twisted yarn Y is cooled and heat-set in the cooling units 23a and 23b. At this time, the twisting device 24a and the twisting device 24b may have opposite twisting directions or the same twisting direction.

  Here, the primary heating units 21a and 21b, the cooling units 23a and 23b, the two twisting devices 24a, and the two twists provided for the four adjacent yarns Y surrounded by the one-dot chain line in FIG. The device 24b is a false twisting unit 20. In this case, in the combined yarn false twisting machine 1, a plurality of false twisting parts 20 are arranged in the machine table longitudinal direction. Further, in each false twisting section 20, the primary heating unit 21b is disposed on the back side ("one side" in the present invention) of the primary heating unit 21a in the machine table longitudinal direction. Moreover, in each false twist processing part 20, the cooling unit 23b is shifted | deviated and arrange | positioned from the cooling unit 23a in the back | inner side of the machine body longitudinal direction.

  In the false twisting section 20, of the four yarns Y, the two yarns positioned on the front side in the longitudinal direction of the machine base (the “other side” in the present invention) when reaching the primary heating units 21a and 21b. Ya1 and Ya2 are heated by the primary heating unit 21a and cooled by the cooling devices 41a and 42a of the cooling unit 23a. Of these four yarns Y, two yarns Yb1 and Yb2 positioned on the far side in the longitudinal direction of the machine base when they reach the primary heating units 21a and 21b are heated by the primary heating unit 21b and cooled. It is cooled by the cooling devices 41b and 42b of the unit 23b.

  Further, in the false twisting section 20, the yarn Ya1 is twisted by a twisting device 24a on the front side in the machine base longitudinal direction (hereinafter sometimes referred to as a twisting device 24a1), and the yarn Ya2 is Twisting is performed by a twisting device 24a on the back side in the direction (hereinafter sometimes referred to as a twisting device 24a2). Further, the yarn Yb1 is twisted by a twisting device 24b on the near side in the machine table longitudinal direction (hereinafter sometimes referred to as a twisting device 24b1), and the yarn Yb2 is twisted on the far side in the machine table longitudinal direction. It twists with the apparatus 24b (henceforth a twisting apparatus 24b2). At this time, as described above, since the twisting device 24a and the twisting device 24b are alternately positioned in the machine table longitudinal direction, the yarn Ya2 and the yarn Yb1 are combined with the primary heating units 21a and 21b and the twisting. It intersects on the yarn path between the devices 24a2, 24b1.

  Here, unlike the present embodiment, the cooling devices 41a and 42a and the cooling devices 41b and 42b can be arranged to extend in parallel to each other. However, as described above, the spacing between the twisting devices 24a and the spacing between the twisting devices 24b in the machine table longitudinal direction are larger than the spacing between the two yarn traveling spaces in the primary heating units 21a and 21b. Therefore, when the cooling devices 41a, 42a, 41b, and 42b are arranged in this way, for example, the yarns Ya2 and Yb1 need to be largely bent between the cooling units 23a and 23b and the twisting devices 24a and 24b. In this case, the propagation of the twist imparted to the yarns Ya2 and Yb1 by the twisting devices 24a and 24b to the upstream portion of the yarn path may be hindered by the bending of the yarns Ya2 and Yb1. The same applies to the case where the yarns Ya1 and Yb2 need to be bent.

  On the other hand, in the present embodiment, as described above, the cooling devices 41a and 42a of the cooling unit 23a and the cooling devices 41b and 42b of the cooling unit 23b are respectively downstream in the yarn path of the yarn Y. The more they extend away from each other in the longitudinal direction of the machine base. Therefore, for example, the yarn Ya2 cooled by the cooling device 42a and the yarn Yb1 cooled by the cooling device 41b do not need to be largely bent. Thereby, propagation of the twist imparted to the yarn Y by the twisting devices 24a and 24b to the upstream portion of the yarn path of the yarn Y can be prevented from being hindered by the bending of the yarn Y. .

  However, if the angle θa formed by the cooling devices 41a and 42a and the angle θb formed by the cooling devices 41b and 42b are too large, for example, the yarn Y may be any of the cooling devices 41a, 42a, 41b, and 42b in the yarn path. It is necessary to bend greatly on the upstream side. Therefore, propagation of the twist imparted to the yarn Y by the twisting devices 24a and 24b to the upstream portion of the yarn path of the yarn Y may be hindered by the bending of the yarn Y. Therefore, in the present embodiment, the angle θa formed by the cooling devices 41a and 42a of the cooling unit 23a and the angle θb formed by the cooling devices 41b and 42b of the cooling unit 23b are set to 10 ° or less. Thereby, the bending of the yarn Y is reduced, and the propagation of the twist imparted to the yarn Y by the twisting devices 24a and 24b to the upstream portion of the yarn path of the yarn Y is inhibited by the bending of the yarn Y. Can be prevented.

  A plurality of tension sensors 30 are individually provided for the plurality of yarns Y, and are arranged on the downstream side of the twisting devices 24a and 24b in the yarn path of the yarn Y. The plurality of tension sensors 30 detect the tension of the yarn Y that has been false twisted by the twisting devices 24a and 24b. The detection result of the tension of the yarn Y by the tension sensor 30 is used for determining the quality of the formed package P, for example.

  The secondary feed rollers 25a and 25b are arranged on the downstream side of the tension sensor 30 in the yarn path of the yarn Y. One secondary feed roller 25a is provided for each set of twisting devices 24a1 and 24b1. One secondary feed roller 25b is provided for each set of twisting devices 24a2 and 24b2. These secondary feed rollers 25a and 25b are alternately arranged in a line in the longitudinal direction of the machine base.

  The secondary feed roller 25a conveys the yarns Ya1 and Yb1 twisted by the twisting devices 24a1 and 24b1 toward the compounding device 26a. The secondary feed roller 25b conveys the yarns Ya2 and Yb2 to which the twist is applied by the twisting devices 24a2 and 24b2 toward the compounding device 26b. Further, the yarn Y in which the twist is thermally fixed between the twist guide 22 and the twisting devices 24a and 24b is untwisted between the twisting devices 24a and 24b and the secondary feed rollers 25a and 25b. As a result, the yarn Y is untwisted. However, as described above, the yarn Y is heat-fixed and thus the filaments are in a temporarily twisted state in which each filament has a wavy shape. Further, the conveying speed of the yarn Y by the secondary feed rollers 25a, 25b is faster than the conveying speed of the yarn Y by the primary feed rollers 19a, 19b, and the yarn Y is fed to the primary feed rollers 19a, 19b and the secondary feed roller. The film is stretched by the difference in transport speed between the rollers 25a and 25b.

  The compounding devices 26a and 26b are disposed on the downstream side of the secondary feed rollers 25a and 25b in the yarn path of the yarn Y. One spinning device 26a (the “first spinning device” of the present invention) is provided for each secondary feed roller 25a. One spinning device 26b (the “second spinning device” in the present invention) is provided for each secondary feed roller 25b. These spinning devices 26a and spinning devices 26b are alternately arranged in a line in the machine table longitudinal direction.

  The compounding device 26a combines the yarn Ya1 to which the twist is imparted by the twisting device 24a1 and the yarn Yb1 to which the twist is imparted by the twisting device 24b1 to form a compound yarn Yg1. The compounding device 26b combines the yarn Ya2 to which the twist is imparted by the twisting device 24a2 and the yarn Yb2 to which the twist is imparted by the twisting device 24b2 to form a compound yarn Yg2.

  Here, in the present embodiment, one of the two yarns Ya1 and Ya2 heated by the primary heating unit 21a and cooled by the cooling unit 23a, and heated by the primary heating unit 21b and cooled by the cooling unit 23b. In order to join one of the two yarns Yb1 and Yb2 cooled by the yarn by the yarn joining devices 26a and 26b, as described above, the yarn Ya2 cooled by the cooling device 42a and the cooling yarn The yarn Yb1 cooled by the device 41b is crossed on the yarn path between the primary heating units 21a and 21b and the twisting devices 24a and 24b.

  On the other hand, unlike the present invention, it is possible to cross the yarn Ya2 and the yarn Yb1 at different positions on the yarn path between the primary heating units 21a, 21b and the twisting devices 24a, 24b. . For example, the yarn Ya2 and the yarn Yb1 can be crossed at a position between the yarn path twisting devices 24a and 24b and the yarn joining devices 26a and 26b.

  In order to cross the yarn Ya2 and the yarn Yb1 at the position between the yarn path twisting devices 24a and 24b and the yarn joining devices 26a and 26b, for example, as shown in FIG. 24b are arranged in a line without shifting from the longitudinal direction of the machine base. Alternatively, as shown in FIG. 6, the twisting device 24a and the twisting device 24b are arranged so as not to overlap each other when viewed from the machine table longitudinal direction. Further, in each false twisting section 20, the two heating devices 24b are arranged on the far side in the machine table longitudinal direction from the two twisting devices 24a. And in each false twist processing part 20, rather than the case of Drawing 5, two twisting devices 24a and two twisting devices 24b are packed and arranged in the machine body longitudinal direction.

  However, in the case shown in FIG. 5, since all the twisting devices 24a and 24b are arranged in a line in the machine longitudinal direction, the twisting device 24a is compared with the case of the present embodiment. , 24b becomes longer in the longitudinal direction of the machine base. On the other hand, in the case as shown in FIG. 6, the twisting device 24b1 and the twisting device 24a2 can be arranged in the machine table longitudinal direction, and compared with the case of FIG. 5, the twisting device 24a, The length of the space required for arranging 24b in the machine table longitudinal direction is shortened. However, as compared with the case where the twisting device 24a and the twisting device 24b are alternately positioned in the longitudinal direction of the machine base as in the present embodiment, the space necessary for arranging the twisting devices 24a and 24b. The length in the machine table longitudinal direction becomes longer.

  Here, in recent years, it is required to increase the number of packages formed by the combined false false twisting machine from the viewpoint of increasing productivity in the combined false false twisting machine. In order to increase the number of packages formed by the combined yarn false twisting machine, it is necessary to increase the number of twisting devices 24a and 24b. In the case of FIG. 5 and FIG. 6, as described above, the space required for arranging the twisting devices 24 a and 24 b is long in the machine longitudinal direction, so the number of twisting devices 24 a and 24 b and the like. Is increased, the size increase in the machine table longitudinal direction of the yarn false twisting machine which is long in the machine table longitudinal direction becomes remarkable.

  On the other hand, in the present embodiment, as described above, the twisting devices 24a and 24b are arranged so as not to overlap each other when viewed from the longitudinal direction of the machine base and are added in the longitudinal direction of the machine base. Twist devices 24a and 24b are positioned alternately. Thus, the yarn Yb1 cooled by the cooling device 41b and the yarn Ya2 cooled by the cooling device 42a are crossed on the yarn path between the primary heating units 21a and 21b and the twisting devices 24a and 24b. ing. Therefore, compared with the case of FIG. 5, FIG. 6, the length of the machine base longitudinal direction of the space required in order to arrange | position twisting apparatus 24a, 24b can be shortened. As a result, in this embodiment, compared with the case of FIG. 5 or FIG. 6, the combined false false twisting machine which is long in the machine table longitudinal direction when the number of twisting devices 24 a, 24 b, etc. is increased. The increase in size in the machine table longitudinal direction can be suppressed as much as possible.

The plurality of tertiary feed rollers 28 are arranged in a line in the longitudinal direction of the machine base. The tertiary feed roller 28 conveys the combined yarns Yg 1 and Yg 2 that have been subjected to the relaxation heat treatment toward the winding unit 13. Further, the tertiary feed roller 28 is arranged at a distance from the secondary heating unit 27 in the machine width direction. A work table or work carriage (not shown) is provided in the space between the secondary heating unit 27 and the tertiary feed roller 28, and an operator performs operations such as threading on the work table or the work carriage.

In the combined false false twisting machine disclosed in Patent Document 1, a plurality of yarns supplied from a yarn supplying unit includes a heater for heating the yarn (corresponding to the “heating unit” of the present invention), and a cooling zone for cooling the yarn (the present invention). And a false twist spindle (corresponding to the “twisting device ” of the present invention) in order, and false twisting is applied to the yarn during this period. Two or more of the plurality of false twisted yarns are combined in a mixing nozzle (corresponding to the “spinning device” of the present invention), and winding means (corresponding to the “winding device” of the present invention) ).

The combined false false twisting machine according to the first aspect of the invention is characterized in that false twisting is performed on a plurality of yarns, and a plurality of yarns subjected to false twisting are combined two by two, which is long in the machine table longitudinal direction. A combined false false twisting machine, wherein a plurality of yarns are supplied to a yarn supplying unit, and the four yarns are arranged in the longitudinal direction of the machine base and supplied from the yarn supplying unit. A plurality of false twisting portions to be processed, and a plurality of yarns that are arranged in the longitudinal direction of the machine base and each two yarns out of four yarns that have been false twisted in each false twisting portion And a plurality of winding devices for winding the yarns combined with each other, and each false twisting section heats two of the four yarns. a first heating section, the disposed one side of the machine base longitudinal direction than the first heating portion to heat the another two yarns from the first heating portion of the thread of the four 2 heating units, a first cooling unit that cools the two yarns heated by the first heating unit, and the first cooling unit are arranged shifted to the one side in the machine table longitudinal direction, A second cooling unit that cools the two yarns heated by the second heating unit; two first twisting devices that impart twist to the two yarns cooled by the first cooling unit; Two second twisting devices for imparting twist to the two yarns cooled by the two cooling sections, and the compound yarn device is the machine longitudinal direction of the two first twisting devices. Among the two second twisting devices, the yarn twisted by the first twisting device on the other side and the second twisting device on the other side in the machine longitudinal direction of the two second twisting devices. Of the two first twisting devices, the first twisting on the one side in the machine table longitudinal direction of the first yarn twisting device that combines the applied yarns A first yarn that is twisted by the first twisting device and a yarn that is twisted by the second twisting device on the one side in the longitudinal direction of the machine base among the two second twisting devices. Two first yarn twisting devices, and the two first twisting devices and the two second twisting devices are arranged so as not to overlap each other when viewed from the longitudinal direction of the machine base, and In the longitudinal direction of the machine base, the first twisting device and the second twisting device are arranged alternately.

According to the present invention, it is possible to reduce the bending of the yarn from the heating unit to the twisting device through the cooling unit, compared to the case where the two cooling devices extend in parallel with each other. Here, in order to perform false twisting on the yarn, it is necessary to propagate the twist imparted to the yarn by the twisting device to the upstream portion of the yarn path of the yarn. In the present invention, as described above , the yarn bending from the heating portion to the twisting device via the cooling portion is small, and therefore, the propagation of the twist can be prevented from being hindered by the yarn bending.

It is a schematic structure figure of the combined yarn false twist processing machine concerning an embodiment of the invention. It is a diagram showing a yarn path of the yarn in the doubling false twister. (A) is sectional drawing which shows the cross section orthogonal to the running direction of the thread | yarn of two adjacent primary heating units, (b) is the (alpha) -alpha sectional view taken on the line of (a). It is a view of two cooling units adjacent false twisting unit taken in the direction of arrow β in FIG. It is a figure equivalent to FIG. 2 which shows an example in the case of making a thread | yarn cross between a twisting apparatus and a combined yarn apparatus different from this invention. FIG. 6 is a view corresponding to FIG. 2, showing an example different from FIG. 5, in the case where the yarn is crossed between the twisting device and the yarn joining device, which is different from the present invention.

The primary heating unit 21a (the “first heating unit” of the present invention) and the primary heating unit 21b (the “second heating unit ” of the present invention) are arranged on the downstream side of the primary feed roller 19 in the yarn path of the yarn Y. Has been. A plurality of primary heating units 21a and 21b are provided. Each of the primary heating units 21 a and 21 b corresponds to two yarns Y among the plurality of yarns Y supplied from the creel stand 11. The primary heating unit 21a and the primary heating unit 21b are alternately arranged in a line in the longitudinal direction of the machine base. As shown in FIGS. 3A and 3B, the primary heating units 21 a and 21 b include a box 31, a heating block 32, a heater 33, and a temperature sensor 34.

And if the electric current which flows into the heater 33 is individually controlled by the primary heating unit 21a and the primary heating unit 21b in this way, the primary heating unit 21a and the primary heating unit 21b according to the type of the yarn Y, etc. Thus, the heating temperature of the yarn Y can be varied. For example, when the yarn Y heated in the primary heating unit 21a is a cationic dyeable polyester yarn (CD yarn) and the yarn Y heated in the primary heating unit 21b is a polyester yarn, the heating block of the primary heating unit 21a The temperature of 32 is made higher than the temperature of the heating block 32 of the primary heating unit 21b. Thereby, a cationic dyeable polyester yarn and a polyester yarn can each be heated to appropriate temperature.

Cold 却Yu knit 23a has two cooling devices 41a, and a 42a. The cooling unit 23b includes two cooling devices 41b and 42b. The cooling devices 41a, 42a, 41b, and 42b are, for example, a metal material or a ceramic material that forms a gap for running the yarn Y so as to face each other as described in Japanese Patent Application Laid-Open No. 2011-047074. A pair of plate-like members composed of, for example, a duct for communicating with the gap and sucking the air in the gap to generate an air flow in the gap. The yarn traveling in this gap is cooled by the air flowing through this gap. Alternatively, the cooling devices 41a, 42a, 41b, and 42b include a pair of plate-like members made of a metal material, a ceramic material, or the like, as described above, and the yarn that travels through the gap contacts the plate-like member. It may be cooled by doing so.

Moreover, as shown in FIG. 4, the cooling devices 41a and 42a are connected and integrated with each other at the outer end in the machine width direction (upstream side of the yarn path), and are substantially V-shaped. Yes. Thereby, the cooling devices 41a and 42a are separated in the machine table longitudinal direction as they go to the downstream side of the yarn path. Further, the angle θa formed between the cooling device 41a and the cooling device 42a is 10 ° or less (for example, about 5 °). Similarly, the cooling devices 41b and 42b are connected and integrated with each other at the outer end in the machine width direction (upstream side of the yarn path), and are substantially V-shaped. Thus, a cooling device 41 b and 42 b are toward the downstream side of the yarn path, away machine frame longitudinally. Further, the angle θb formed between the cooling device 41b and the cooling device 42b is 10 ° or less (for example, about 5 °).

Further, the cooling unit 23a and the cooling unit 23b are arranged so as to be shifted from each other when viewed from the longitudinal direction of the machine base. As shown in FIG. 4, the cooling device 42a of the cooling unit 23a and the cooling device 41b of the cooling unit 23b intersect each other. Therefore, it is possible to arrange the cooling units 23a and 23b at a higher density in the machine table longitudinal direction than in the case where the cooling units 23a and 23b are arranged in the machine table longitudinal direction apart from the cooling device 42a and the cooling device 41b. it can. Thereby, the enlargement to the machine base longitudinal direction of the combined yarn false twist processing machine 1 can be suppressed.

The twisting device 24a (the “first twisting device” of the present invention) twists the yarn Y heated by the primary heating unit 21a and cooled by the cooling unit 23a. Twisting device 24b ( "second twisting device" of the present invention) is heated in the heating unit 21b, to impart twist to the cooled yarn Y in the cooling unit 23 b. At this time, in the yarn Y, twist is applied to a portion between the twisting guide 22 and the twisting devices 24a and 24b. At this time, the yarn Y is twisted while being heated in the primary heating units 21a and 21b, and the twisted yarn Y is cooled and heat-set in the cooling units 23a and 23b. At this time, the twisting device 24a and the twisting device 24b may have opposite twisting directions or the same twisting direction.

The secondary feed roller 25a conveys the yarns Ya1 and Yb1 twisted by the twisting devices 24a1 and 24b1 toward the compounding device 26a. The secondary feed roller 25b conveys the yarns Ya2 and Yb2 to which the twist is applied by the twisting devices 24a2 and 24b2 toward the compounding device 26b. Further, the yarn Y in which the twist is thermally fixed between the twist guide 22 and the twisting devices 24a and 24b is untwisted between the twisting devices 24a and 24b and the secondary feed rollers 25a and 25b. As a result, the yarn Y is untwisted. However, as described above, the yarn Y is heat-fixed and thus the filaments are in a temporarily twisted state in which each filament has a wavy shape. The secondary feed roller 25a, conveying speed of the yarn Y by 25b is faster than the transport speed of the yarn Y by the primary feed roller 1 9, the yarn Y, the primary feed roller 1 9 and the secondary feed roller The film is stretched by the difference in transport speed between 25a and 25b.

In order to cross the yarn Ya2 and the yarn Yb1 at the position between the yarn path twisting devices 24a and 24b and the yarn joining devices 26a and 26b, for example, as shown in FIG. 24b are arranged in a line without shifting from the longitudinal direction of the machine base. Alternatively, as shown in FIG. 6, the twisting device 24a and the twisting device 24b are arranged so as not to overlap each other when viewed from the machine table longitudinal direction. Further, in each false twisting section 20, the two twisting devices 24b are arranged on the far side in the machine table longitudinal direction from the two twisting devices 24a. And in each false twist processing part 20, rather than the case of Drawing 5, two twisting devices 24a and two twisting devices 24b are packed and arranged in the machine body longitudinal direction.
