Therefore, the first cooling device 41a and the second cooling device 41b cannot be arranged to be shifted from each other in a direction orthogonal to the lower surface of the common ducts 42, 43 (as viewed from the longitudinal direction of the body). As a result, as described above, when the first heating device 32a and the second heating device 32b, and the first twisting device 24a and the second twisting device 24b are arranged to be shifted from each other, the heating devices 32a and 32b cannot be used.

Further, the conveying speed of the yarn Y conveyed by the secondary feeding roller 25 is faster than the conveying speed of the yarn Y conveyed by the primary feeding roller 20, and the yarn Y is passed by the primary feeding roller 20 and the secondary feeding roller 25 Stretched by the difference in conveying speed. Further, the yarn Y that has been thermally fixed between the snagging yarn guide 22 and the twisting device 24 is untwisted between the twisting device 24 and the secondary yarn feeding roller 25. As a result, the enthalpy of the yarn Y is released, but since the enthalpy of the yarn Y has been thermally fixed, each of the filaments has a false state in a wavy form.

Further, the winding device 60 includes a cradle 61, a winding roller 62, and a traverse device 63 as shown in Figs. 9(a) and 9(b).

In the cradle 61, one bobbin B1 can be attached as shown in Fig. 9(a). Further, when two yarns Y are to be woven in the yarn joining device 26, one bobbin B1 is attached to the cradle 61. Further, as shown in FIG. 9(b), in the cradle 61, instead of the one bobbin B1, two bobbins B2 whose axial length is approximately half of the bobbin B1 and which are connected in the axial direction may be attached. Further, when the two yarns Y are not to be woven in the yarn joining device 26, the two bobbins B2 are attached to the cradle 61.

The bobbins B1 and B2 attached to the cradle 61 are disposed such that their axial directions are parallel to the longitudinal direction of the body, and are rotatably supported by the cradle 61. The winding roller 62 extends in the longitudinal direction of the machine body, and is mounted on the surface of the bobbins B1 and B2 attached to the cradle 61, and the package P1 formed by winding the yam Ya of the two yarns Y in the bobbin B1. The surface of the package P2 formed by winding the yarn Y in the bobbin B2 is in contact. The winding roller 62 is connected to the winding motor 64. When the winding motor 64 is driven, the winding roller 62 rotates, and in conjunction with this, the bobbins B1 and B2 or the packages P1 and P2 that are in contact with the winding roller 62 rotate. Thereby, the yam Ya is wound around the bobbin B1, or the yarn Y is wound around the bobbin B2. Here, the winding motor 64 may directly drive the bobbins B1 and B2 attached to the cradle 61. At this time, the winding roller 62 becomes a driven roller that rotates in conjunction with the rotation of the bobbins B1 and B2.

The traverse device 63 is disposed on the upstream side of the cradle 61 and the winding roller 62 in the yarn path of the yarn Y. The traverse device 63 has three pulleys 66a to 66c, an endless belt body 67, and two traverse guides 68. The pulley 66a and the pulley 66b are arranged at intervals in the longitudinal direction of the body.

The two traverse guides 68 are attached to the portion of the belt body 67 between the pulleys 66a and 66b with a space therebetween. Further, one of the two traverse guides 68 can be detached from the belt 67.

Further, when two yarns Y are to be yamed in the yarn joining device 26, as shown in Fig. 9(a), the one traverse yarn guide 68 is detached from the belt body 67 in advance, from the yarn. The yam Ya fed from the processing unit 12 to the winding unit 13 is hung by the other traverse guide 68 and then conveyed toward the winding roller 62. On the other hand, when it is not necessary to perform the doubling of the two yarns Y in the yarn joining device 26, as shown in Fig. 9(b), both of the two traverse yarn guides 68 are attached to the belt body 67, Among the yarns Y conveyed from the yarn processing unit 12 toward the winding unit 13, the yarn Y subjected to the false twist processing by the first twisting device 24a is wound toward the one of the traverse guides 68. The roller 62 is conveyed, and the yarn Y subjected to the false twist processing by the second twisting device 24b is conveyed toward the winding roller 62 after being hung on the other traverse guide 68.

When the traverse device 63 drives the traverse motor 69 to rotate the pulley 66c forward and backward, the belt body 67 travels and the pulleys 66a and 66b are driven to rotate. Thereby, the traverse guide 68 reciprocates in the axial direction (the longitudinal direction of the body) of the bobbins B1, B2, so that the yam Ya or the yarn Y hanging on the traverse guide 68 is along the bobbins B1, B2.

Next, the control device 10 that controls the operation of the false twisting machine 1 will be described. The control device 10 is configured by a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), or the like. Further, the control device 10 is connected to the blowers 46a and 46b (strictly, the motors for driving the blowers 46a and 46b) through the inverter circuit 54 as shown in Figs. 1 and 5, by performing the inverter circuit 54. The control controls the actions of the blowers 46a, 46b. Here, the inverter circuit 54 may be provided individually for each of the blowers 46a and 46b, or may be provided in common to the two or more blowers 46a and 46b.

Further, the control device 10 is connected to the heat generating member 36 of each of the heating devices 32a and 32b as shown in Figs. 1, 3, and 4, and is controlled to flow through the heat generating member by controlling the current applying circuit 29. 36 current. Here, the current applying circuit 29 may be provided separately for each of the heat generating members 36, or may be provided in common to the two or more heat generating members 36. Further, the control device 10 is connected to the temperature sensor 37 as shown in FIGS. 3 and 4, and receives a signal related to the temperature of the heating block 35 from the temperature sensor 37.

In addition, although the detailed description is omitted, the control device 10 is additionally provided with the primary feeding roller 20, the twisting device 24, the tension sensors 30a, 30b, the secondary feeding roller 25, the secondary heating unit 27, The three yarn supplying rollers 28, the winding device 60, the traverse device 63 (motor connected to the pulley 66c), and the like are connected, and the operation of these members is controlled.

Next, the control of the current applying circuit 29 by the control device 10 (temperature control of the heating block 35) will be described. In the ROM or the like of the control device 10, the set temperature of the heating block 35 for the upstream heating portion 34a and the downstream heating portion 34b of each of the heating devices 32a and 32b is stored in advance for each type of the yarn Y, for example. When the operator selects the type of the yarn Y heated in each of the heating devices 32a and 32b by operating the operation unit (not shown), the operator individually determines the heating for each type of the selected yarn Y. The set temperature of the heating block 35 of the upstream side heating portion 34a and the downstream side heating portion 34b in the devices 32a and 32b.

Further, the control device 10 controls the current applying circuit 29 so that the temperature of each of the heating blocks 35 approaches the determined set temperature in accordance with the temperature detected by the temperature sensor 37. More specifically, for example, when the temperature detected by the temperature sensor 37 is lower than the set temperature, the larger the difference from the set temperature, the larger the current flowing through the corresponding heat generating member 36 is. The current control circuit 29 is controlled in a manner. On the other hand, when the temperature detected by the temperature sensor 37 is higher than the set temperature, if the difference from the set temperature is larger, the current is applied so that the current flowing through the corresponding heat generating member 36 is smaller. Circuit 29.

Further, by controlling the current supply circuit 29 by the control device 10 as described above, in the present embodiment, the temperature of the heating block 35 of the upstream heating portion 34a of each of the heating devices 32a and 32b and the respective heating devices 32a can be individually controlled. The temperature of the heating block 35 of the downstream side heating portion 34b in 32b. Thus, in the yarn processing unit 12, for a plurality of types When the yarn Y (for example, a different yarn such as a material or a thickness) is imparted to the crucible, each of the yarns Y can be individually heated to a temperature suitable for the crucible by the twisting device 24 corresponding to the type.

For example, the yarn Y that travels in the yarn running groove 38 of the first heating device 32a is a cationic dyeable polyester yarn (CD yarn), and the yarn that travels in the yarn running groove 38 of the second heating device 32b. When Y is a polyester yarn, the temperature of the heating block 35 of the upstream heating portion 34a of the second heating device 32b is higher than the temperature of the heating block 35 of the upstream heating portion 34a of the first heating device 32a, and The temperature of the heating block 35 of the downstream side heating portion 34b of the heating device 32b is higher than the temperature of the heating block 35 of the downstream side heating portion 34b of the first heating device 32a. Thereby, the amount of heat imparted to the polyester yarn can be made larger than the amount of heat imparted to the cationic dyeable polyester yarn. Here, the cationic dyeable polyester yarn refers to a polyester yarn in a state of being easily dyed by a cationic dye. In the present embodiment, since the heat imparted to the cationic dyeable polyester yarn can be made different from the heat imparted to the polyester yarn, the cationic dyeable polyester yarn and the polyester yarn can be separately heated to an appropriate temperature. .

Further, in the present embodiment, as described above, in each of the heating devices 32a and 32b, the length of the heating block 35 of the downstream heating portion 34b in the width direction of the body is larger than the width direction of the heating block 35 of the upstream heating portion 34a. The length is long. Further, as described above, in each of the heating devices 32a and 32b, the set temperature of the heating block 35 with respect to the upstream side heating portion 34a is higher than the set temperature of the heating block 35 with respect to the downstream side heating portion 34b. Thus, in each of the heating devices 32a, 32b, the yarn Y is added on the upstream side. When the yarn travels in the yarn running groove 38 of the hot portion 34a, the temperature rises sharply in a short time, and then, when traveling in the yarn running groove 38 of the downstream heating portion 34b, the yarn is consumed more than the yarn in the upstream heating portion 34a. The walking groove 38 travels for a longer period of time while the temperature rises slowly.

Further, in the present embodiment, as described above, the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b are arranged so as to be vertically viewed from the longitudinal direction of the body so as not to overlap even partially. The directions are staggered from each other. Therefore, compared with the case where the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b are completely overlapped from the longitudinal direction of the machine body or partially overlapped as in the fifth modification described later, it is difficult to generate the first 1 heat transfer between the heating block 35 of the heating device 32a and the heating block 35 of the second heating device 32b. Further, in the present embodiment, a plurality of heat insulating members 33 are disposed so as to fill a gap in which the storage spaces 31a of the heating devices 32a and 32b are housed. Therefore, the heating block 35 and the second heating in the first heating device 32a are provided. It is more difficult to generate heat transfer between the heating blocks 35 of the device 32b.

Accordingly, in the present embodiment, it is difficult to generate thermal interference between the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b. Therefore, the temperature of the heating block 35 of each of the heating devices 32a and 32b can be surely set to the set temperature.

Further, as described above, in order to heat the cationic dyeable polyester yarn and the polyester yarn by the heating devices 32a and 32b, the set temperature of the heating block 35 of the upstream heating portion 34a of the second heating device 32b is set to be higher than that of the first heating device 32b. The heating block 35 of the upstream side heating portion 34a of the heating device 32a is provided When the set temperature of the heating block 35 of the downstream heating portion 34b of the second heating device 32b is higher than the set temperature of the heating block 35 of the downstream heating portion 34b of the first heating device 32a, the second heating device is high. The heat of the heating block 35 of 32b is hard to be transmitted to the heating block 35 of the first heating device 32a located below the second heating device 32b. Therefore, in this case, the temperature of the heating block 35 of each of the heating devices 32a and 32b can be more reliably set to the set temperature.

Further, when the yarn Y that travels in the yarn running groove 38 of the first heating device 32a and the yarn Y that travels in the yarn running groove 38 of the second heating device 32b are the same type of yarn, In the first heating device 32a and the second heating device 32b, the set temperatures of the heating blocks 35 of the upstream heating portion 34a are made the same, and the set temperatures of the heating blocks 35 of the downstream heating portion 34b are the same. Thus, even in such a case, the yarn Y can be heated to an appropriate temperature.

Next, the control of the blowers 46a and 46b by the control device 10 will be described. When the yarn Y that travels in the gap 51c of the first cooling device 41a and the yarn Y that travels in the gap 51c of the second cooling device 41b are the same kind of yarn, the control device 10 causes the blowers 46a, 46b to Rotate at the same speed. Thereby, the flow of air of the same degree is generated in the gap 51c of the first cooling device 41a and the gap 51c of the second cooling device 41b, and the yarn Y traveling in the gap 51c of the first cooling device 41a and the second cooling are performed. The yarn Y traveling in the gap 51c of the device 41b is cooled to the same extent.

On the other hand, when walking in the gap 51c of the first cooling device 41a When the yarn Y is different from the type (material, thickness, and the like) of the yarn Y that travels in the gap 51c of the second cooling device 41b, the control device 10 makes the blowers 46a and 46b different depending on the type of the yarn Y. The rotation speed is rotated, whereby the flow velocity of the air in the internal space 42a of the first common duct 42 is different from the flow velocity of the air in the internal space 43a of the second common duct 43. Thereby, the flow velocity of the air flowing through the gap 51c of the first cooling device 41a and the flow velocity of the air flowing through the gap 51c of the second cooling device 41b can be made to travel in the gap 51c of the first cooling device 41a. The yarn Y and the yarn Y traveling in the gap 51c of the second cooling device 41b are cooled to an appropriate level corresponding to the type of the yarn Y.

For example, when the yarn Y cooled by the first cooling device 41a is a cationic dyeable polyester yarn, and the yarn Y cooled by the second cooling device 41b is a polyester yarn, the rotation speed of the second blower 46b is made. The first blower 46a has a high rotation speed, and the heat taken away from the polyester yarn can be made larger than the heat taken away from the cationic dyeable polyester yarn. In the present embodiment, since the heat taken away from the cationic dyeable polyester yarn can be different from the heat taken away from the polyester yarn, the cationic dyeable polyester yarn and the polyester yarn can be separately cooled to appropriate. temperature.

Next, a modification in which various changes are applied to the present embodiment will be described.

In the above-described embodiment, the first cooling device 41a is connected to the first common pipe 42. However, the second cooling device 41b is connected to the second common pipe 43. However, the present invention is not limited thereto. In the first modification, as shown in FIG. 10, the first common duct 42 is disposed in the above embodiment. In the manner of the region of the second common duct 43, one common duct 111 ("first common duct" of the present invention) is disposed. Further, the connecting pipes 44, 45 are all connected to the common pipe 111.

Even in this case, similarly to the above-described embodiment, the first cooling device 41a and the second cooling device 41b can be disposed in accordance with the arrangement of the heating devices 32a and 32b and the twisting devices 24a and 24b, and the appropriate yarn can be maintained. The bending angle of Y is on the yarn path. Further, in this case, unlike the above-described embodiment, the flow velocity of the air flowing through the gap 51c cannot be individually changed in the first cooling device 41a and the second cooling device 41b. However, for example, the yarn Y cooled by the first cooling device 41a and the yarn Y cooled by the second cooling device 41b are the same type of yarn or the like, and it is not necessary to use the first cooling device 41a and the second cooling. When the degree of cooling of the yarn Y by the device 41b is different, there is no problem.

In the above-described embodiment, the gap 51c of the first cooling device 41a communicates with the internal space 42a of the first common duct 42 through the first connecting duct 44, and the gap 51c of the second cooling device 41b passes through the second connecting duct. 45 is connected to the internal space 43a of the second common duct 43, but is not limited thereto. In the second modification, as shown in FIGS. 11(a) and 11(b), the gap 51c of the first cooling device 41a passes through the individual duct 52, the first connecting duct 44, and the first common duct 121 as in the above-described embodiment. The internal space 121a is connected. On the other hand, the opposing members 51a and 51b of the second cooling device 41b are directly attached to the lower surface of the second common duct 122. Further, a plurality of communication holes are formed in a portion of the lower surface of the second common duct 122 that overlaps with the gap 51c of the second cooling device 41b. 123. Thereby, the gap 51c of the second cooling device 41b is connected to the internal space 122a of the second common duct 122 through the plurality of communication holes 123.

Further, in the third modification, as shown in FIGS. 12(a) and 12(b), the communication hole 131b is formed in the side surface of the common duct 131, and the first connection duct 132 is connected to the communication hole 131b, whereby the first The internal space 132a of the connecting duct 132 communicates with the internal space 131a of the common duct 131. Thereby, the gap 51c of the first cooling device 41a is connected to the internal space 131a of the common pipe 131 through the individual duct 52 and the first connecting duct 132. Further, the opposing members 51a and 51b of the second cooling device 41b are directly attached to the lower surface of the common duct 131. Further, a plurality of communication holes 131c are formed in a portion of the lower surface of the common duct 131 that overlaps with the gap 51c of the second cooling device 41b. Thereby, the gap 51c of the second cooling device 41b is connected to the internal space 122a of the common pipe 122 through the plurality of communication holes 131c.

In the case of the second and third modifications, the second connecting duct 45 is not provided. Therefore, the second cooling device 41b cannot be disposed apart from the common ducts 122 and 131. In other words, the position of the second cooling device 41b in the direction orthogonal to the lower surfaces of the common pipes 122 and 131 cannot be changed. However, even in this case, as in the above-described embodiment, the position of the first cooling device 41a in the direction orthogonal to the lower surfaces of the common pipes 122 and 131 can be changed. When the position of the first cooling device 41a in the direction orthogonal to the lower surface of the common pipes 122 and 131 is changed, the first cooling device 41a and the second direction in the direction orthogonal to the lower surfaces of the common pipes 122 and 131 are changed. The positional relationship between the cooling devices 41b is changed. So even in In the case of the second and third embodiments, the degree of freedom in the arrangement of the first cooling device 41a and the second cooling device 41b is lower than that of the above-described embodiment, but the first cooling device 41a and the second cooling device 41b are adjusted. In the positional relationship between the heating devices 32a and 32b and the twisting devices 24a and 24b, the first cooling device 41a and the second cooling device 41b can be disposed in a yarn capable of maintaining a proper bending angle of the yarn Y. On the channel.

Further, even in the case of the second and third modifications, the first cooling device 41a is located on the opposite side to the common pipes 122 and 131 with respect to the second cooling device 41b. However, even in the second and third modifications, the connection duct 44 is provided for each of the two adjacent first cooling devices 41a. Therefore, the gap 51c of the first cooling device 41a can be communicated with the internal spaces 122a and 131a of the common pipes 122 and 131 through the first connecting duct 44.

Further, in the above-described embodiment, one first connecting duct 44 is connected to the communication hole 52c of the individual ducts 52 of the two first cooling devices 41a, and one second connecting duct 45 and two second cooling devices are connected. The communication hole 52c of the individual duct 52 of 41b is connected, but is not limited thereto. The one first connecting duct 44 may be connected to the communication hole 52c of the individual ducts 52 of the one first cooling device 41a. Alternatively, the one first connecting duct 44 may be connected to the communication hole 52c of the individual ducts 52 of the three or more first cooling devices 41a. The second connection duct 45 is also the same.

Further, in the above-described embodiment, the two first heating devices 32a and the two second heating devices 32b are housed in one case 31, but the invention is not limited thereto. For example, in Modification 4, as shown in FIG. 13(a), One of the first heating devices 32a and one second heating device 32b are housed in one of the casings 31. Further, in the fifth modification, as shown in FIG. 13(b), three first heating devices 32a and three second heating devices 32b are housed in one casing 31. In addition, in (a) and (b) of FIG. 13, the illustration of the current supply circuit 29 and the control apparatus 10 shown in FIG. 3 is abbreviate|omitted.

Even in these cases, the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b are disposed so as to be shifted from each other so as not to overlap from the longitudinal direction of the body. Therefore, similarly to the above-described embodiment, it is less likely that thermal interference occurs between the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b, and each heating block 35 can be surely heated to a set temperature. Further, four or more first heating devices 32a and four or more second heating devices 32b may be housed in one case 31.

Further, in the above-described embodiment, the first heating device 32a and the second heating device 32b are housed in one case 31, but the invention is not limited thereto. For example, the case 31 in which only one first heating device 32a is housed and the case 31 in which only one second heating device 32b is housed may be arranged in the longitudinal direction of the body.

Further, in the above-described embodiment, the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b are disposed so as to be displaced from each other in the vertical direction so as not to overlap from the longitudinal direction of the body, but Limited to this. For example, in Modification 6, as shown in FIG. 14, the heating block 35 of the first heating device 32a and the heating block of the second heating device 32b The 35s are arranged to be shifted from each other in the vertical direction, but the amount of shift is smaller than that of the above-described embodiment, and the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b partially overlap each other as viewed from the longitudinal direction of the body. However, in the sixth modification, in order to avoid direct contact between the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b, the heating block 35 and the second heating device 32b of the first heating device 32a. The heating block 35 is separated in the longitudinal direction of the body, and a heat insulator 33 is also disposed between the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b in the longitudinal direction of the machine body. In addition, in FIG. 14, the illustration of the current supply circuit 29 and the control apparatus 10 illustrated in FIG. 3 is abbreviate|omitted.

Even in this case, when the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b are completely overlapped from the longitudinal direction of the machine body, it is difficult to generate the heating of the first heating device 32a. Thermal interference between the block 35 and the heating block 35 of the second heating device 32b.

Further, the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b are not limited to being arranged to be shifted from each other as viewed in the longitudinal direction of the body. For example, when the interval between the first heating device 32a and the second heating device 32b in the longitudinal direction of the machine body is sufficiently large, the heating block 35 of the first heating device 32a and the heating block 35 of the second heating device 32b may be provided. Observe completely overlapping from the length of the body.

Further, in the above-described embodiment, the setting temperatures of the heating block 35 are different in the first heating device 32a and the second heating device 32b. In the example, the setting temperature of the heating block 35 of the upstream heating portion 34a of the second heating device 32b is higher than the set temperature of the heating block 35 of the upstream heating portion 34a of the first heating device 32a, and the second heating is performed. The set temperature of the heating block 35 of the downstream side heating portion 34b of the device 32b is higher than the set temperature of the heating block 35 of the downstream side heating portion 34b of the first heating device 32a, but is not limited thereto. The set temperature of the heating block 35 of the upstream heating portion 34a of the second heating device 32b may be lower than the set temperature of the heating block 35 of the upstream heating portion 34a of the first heating device 32a. Further, the set temperature of the heating block 35 of the downstream side heating portion 34b of the second heating device 32b may be lower than the set temperature of the heating block 35 of the downstream side heating portion 34b of the first heating device 32a.

In the above-described embodiment, the first heating device 32a and the second heating device 32b are different in the setting temperature of the heating block 35, but the invention is not limited thereto. .

For example, the set temperature of the heating block 35 may be different between the two first heating devices 32a or between the two second heating devices 32b. When the first heating device 32a and the second heating device 32b are alternately arranged in the longitudinal direction of the body as in the above-described embodiment, the second heating device 32b is disposed in the adjacent two first heating devices in the longitudinal direction of the machine body. Between 32a, the first heating device 32a is disposed between the adjacent two second heating devices 32b. Therefore, the two first heating devices 32a are disposed to be separated in the longitudinal direction of the body, and the two second heating devices 32b are disposed so that They are separated from each other in the length direction of the body. Further, a heat insulator 33 is interposed between the two first heating devices 32a and between the two second heating devices 32b. by Therefore, it is difficult to generate heat transfer between the heating blocks 35 of the two first heating devices 32a and between the heating blocks 35 of the two second heating devices 32b. Therefore, even in this case, the heating block 35 can be surely set to the set temperature in each of the first heating device 32a and each of the second heating devices 32b.

Further, in the above-described embodiment, the primary heating unit 21 is configured to individually set the set temperature of the heating block 35 of the upstream heating portion 34a of each of the heating devices 32a and 32b. However, the present invention is not limited thereto. For example, the heat generating members 36 of the upstream heating portions 34a of all the heating devices 32a and 32b may be connected to each other or the like so that the set temperatures of the heating blocks 35 of the upstream heating portion 34a cannot be made different between the heating devices 32a and 32b. . Similarly, in the above-described embodiment, the set temperature of the heating block 35 of the downstream heating portion 34b of each of the heating devices 32a and 32b can be individually set, but the present invention is not limited thereto. For example, the heat generating members 36 of the downstream side heating portions 34b of all the heating devices 32a and 32b may be connected to each other or the like so that the set temperatures of the heating blocks 35 of the downstream side heating portions 34b cannot be made different between the heating devices 32a and 32b. .

Further, in the above-described embodiment, the heating devices 32a and 32b include the upstream heating portion 34a and the downstream heating portion 34b, but are not limited thereto. For example, the heating devices 32a and 32b may have one heating unit that adds the length of the upstream heating portion 34a to the length of the downstream heating portion 34b in the machine width direction.

Further, in the above-described embodiment, it is possible to switch between the two yarns Y in the yarn joining device 26 and the yarns in the winding device 60. The yarn Ya is wound around one bobbin B1; and the two yarns Y are not entangled, and the two yarns Y are wound around the two bobbins B2, respectively, but the invention is not limited thereto. The winding device 60 may always wind the yam Ya in one bobbin B1. Alternatively, the yarn joining device 26 may not be provided, and the winding device 60 always winds the yarn Y around the two bobbins B2. Further, in this case, the directions of the twisting in the first twisting device 24a and the second twisting device 24b may be the same direction.

Further, in the above-described embodiment, one winding device 60 is provided for two adjacent twisting devices 24 (one first twisting device 24a and one second twisting device 24b), but Limited to this. For example, the winding device 26 may not be provided, and one winding device 60 may be provided for one twisting device 24. Further, in this case as well, the directions of the twisting in the first twisting device 24a and the second twisting device 24b may be the same direction. Further, in this case, the secondary heating unit 27 may have the same configuration as the primary heating unit 21. In this case, the yarn Y subjected to the false twist processing by the first twisting device 24a and the yarn Y subjected to the false twist processing by the second twisting device 24b can be heated to correspond to the type of the yarn Y. The appropriate degree.

Further, in the above-described embodiment, the inclination of the running direction of the yarn Y in the cooling devices 41a and 41b with respect to the horizontal direction is small, but the invention is not limited thereto. For example, the present invention can be applied to a false twisting machine in which the running direction of the yarn in the cooling device described in Japanese Laid-Open Patent Publication No. H11-107084 is greatly inclined with respect to the horizontal direction.

In addition, in the above embodiment, although it is explained, the inverter is used to generate electricity. The path 54 controls the rotational speed of the blowers 46a and 46b to adjust the cooling capacity of the cooling devices 41a and 41b, but is not limited thereto. The cooling air volume may be adjusted in the common pipes 42 and 43 by a flow rate adjusting device such as a butterfly valve that is automatically operated in accordance with an instruction from the control device 10. Further, it is also possible to combine the control of the blowers 46a and 46b by the inverter and the flow rate adjustment by a valve or the like.
