Description

Technical Field

[0001] This invention relates to a heating device for heating wires and a wire processing machine equipped with the heating device. Background Technology

[0002] Patent Document 1 discloses a heat treatment apparatus (heating device) for heating yarn during yarn processing such as false twisting. The heating apparatus includes an armored heater (heat source) and a heater body (heating section). The heating section is configured to be heated by the heat source and to form a predetermined yarn travel space for the yarn to travel. More specifically, the heating section has a heating plate made of a copper alloy. Generally, copper alloys have a relatively large heat capacity. Therefore, it is possible to suppress the cooling of the heating section due to external interference (e.g., external gas entering the yarn travel space for some reason).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2002-146640

[0004] Generally, to reliably suppress temperature fluctuations in the heating element caused by external disturbances, it is sufficient to have a very large heat capacity in the heating element. However, in this case, the heating device may become very large. Therefore, considering the balance between suppressing the large size of the device and suppressing temperature fluctuations caused by external disturbances, the heating element is generally designed to have a certain heat capacity. However, in such a configuration, if the temperature of the heating element drops due to external disturbances, the temperature of the wire travel space and / or the components forming the wire travel space (hereinafter referred to as the wire travel space, etc.) also drops. In this case, it may take time for the temperature of the heating element and the wire travel space, etc., to return to the set temperature. Summary of the Invention

[0005] The purpose of this invention is to suppress the temperature drop in the thread travel space and the like caused by external interference, and to enable the thread travel space and the like to heat up rapidly even if the temperature drops.

[0006] The heating device of the first invention comprises: a heat source; a heating section configured to be heated by the heat source and configured to form a thread travel space extending at least along a predetermined first direction, the heating device heating a thread traveling in the thread travel space, characterized in that the heating section comprises: a first heating member configured not to contact the thread traveling in the thread travel space and made of a first material; and a second heating member configured not to contact the thread traveling in the thread travel space in a cross-section orthogonal to the first direction, at least between the heat source and the thread travel space, and made of a second material having a lower volumetric heat capacity than the first material.

[0007] As the first material constituting the first heating element, by using a material with a relatively high volumetric specific heat, the temperature drop of the heating section caused by external interference can be suppressed to a certain extent. Furthermore, in this invention, the second heating element, made of a second material with a low volumetric specific heat, can heat up more rapidly than the first heating element. Thus, the thread travel space and the like can be rapidly heated via the second heating element disposed between the heat source and the thread travel space (detailed definitions will be described later). Therefore, through such rapid heating, the temperature drop of the thread travel space and the like caused by external interference can be suppressed. Furthermore, even if the temperature of the thread travel space and the like drops due to external interference, the thread travel space and the like can be rapidly heated up.

[0008] The heating device of the second invention is characterized in that, in the first invention, the second heating element is in contact with the heat source.

[0009] In this invention, heat generated by a heat source can be rapidly transferred to the second heating element. Therefore, the second heating element can be effectively heated.

[0010] The heating device of the third invention is characterized in that, in the first or second invention, the second heating element is in contact with the first heating element.

[0011] For example, the heat source for heating the first heating element and the heat source for heating the second heating element can be separated, and the second heating element can be separately configured from the first heating element. However, in this case, the manufacturing cost of the heating device increases due to the increased component cost of the heat source. In this invention, the second heating element is in contact with the first heating element. Therefore, the increase in manufacturing cost can be suppressed, and the first heating element can be rapidly heated via the second heating element.

[0012] The heating device of the fourth invention is characterized in that, in any of the first to third inventions described above, the ratio of the heat capacity of the second heating element to the heat capacity of the first heating element is more than 20% and less than 40%.

[0013] If the heat capacity of the second heating element is relatively small, it may take time for the temperature of the heating section to rise again after the temperature drops due to external disturbances. However, if the heat capacity of the second heating element is relatively large, the temperature of the heating section may fluctuate easily even due to minor external disturbances, and the temperature of the thread travel space may become unstable. In this invention, the heat capacity of the second heating element is neither too large nor too small compared to the heat capacity of the first heating element. Therefore, the heating section can be strengthened to a certain extent relative to external disturbances, and the thread travel space can be heated rapidly.

[0014] The heating device of the fifth invention is characterized in that, in any of the first to fourth inventions, the second material comprises a fibrous material.

[0015] In this invention, by orienting the fiber material along a specific direction, the thermal conductivity of the second material can be made anisotropic. Therefore, heat can be transferred very rapidly in directions where heat transfer is particularly easy.

[0016] The heating device of the sixth invention is characterized in that, in the fifth invention described above, the fiber material is carbon fiber.

[0017] Carbon fiber is a lightweight material with high thermal conductivity. Therefore, it can transfer heat very quickly in the direction that facilitates heat transfer. In addition, it enables the weight reduction of heating devices.

[0018] The heating device of the seventh invention is characterized in that, in the sixth invention described above, the carbon fiber is a pitch-based fiber.

[0019] As carbon fibers, pitch-based carbon fibers and PAN-based carbon fibers are generally known. Generally, pitch-based carbon fibers have higher thermal conductivity than PAN-based carbon fibers. In this invention, by using pitch-based carbon fibers, the thermal conductivity can be further improved.

[0020] The heating device of the eighth invention is characterized in that, in the sixth or seventh invention described above, the second material is a composite material of carbon fiber and graphite.

[0021] Carbon fiber and graphite composites have very high thermal conductivity. Therefore, by using carbon fiber and graphite composites as a second material, the thermal conductivity can be further improved.

[0022] The heating device of the ninth invention is characterized in that, in the sixth or seventh invention described above, the second material is a composite material of carbon fiber and resin.

[0023] Carbon fiber and resin composites are cheaper than carbon fiber and graphite composites. Therefore, by using carbon fiber and resin composites as a second material, the increase in the manufacturing cost of the heating device can be suppressed.

[0024] The heating device of the 10th invention is characterized in that, in any of the inventions of the 1st to 9th, the second heating element is configured to extend at least along the first direction, and the second material has a higher thermal conductivity in at least the first direction compared to the first material.

[0025] In this invention, heat can be rapidly transferred in the first direction via the second heating element. Therefore, temperature deviations in the filament travel space, etc., in the first direction can be suppressed.

[0026] The heating device of the 11th invention is characterized in that, in any of the 1st to 10th inventions, in a cross-section orthogonal to the first direction, when the direction extending from the heat source toward the space in which the filament travels is defined as the second direction, the second material has a higher thermal conductivity in at least the second direction compared to the first material.

[0027] In this invention, heat can be rapidly transferred from a heat source to the yarn travel space via the second heating element. Therefore, the yarn travel space can be rapidly heated.

[0028] The heating device of the 12th invention is characterized in that, in any of the 1st to 11th inventions described above, the heating part has a contact member extending at least along the first direction for contacting the filament.

[0029] In a configuration with a contact member as described in this invention, the contact member can be effectively heated by rapidly heating the second heating member.

[0030] The heating device of the 13th invention is characterized in that, in the 12th invention described above, the contacting member is in contact with the second heating member described above.

[0031] In this invention, the contact component can be effectively heated through heat conduction between the contact component and the rapidly heating second heating component.

[0032] The heating device of the 14th invention is characterized in that, in the 12th or 13th invention described above, the contact member is configured to be detachable from the heating part.

[0033] Normally, when processing a thread while it is being moved, an oil is applied to the thread to ensure its smooth movement. If this oil and / or residue accumulates on the contact parts, it may hinder the normal movement of the thread; therefore, the contact parts need to be cleaned regularly. In this invention, since the contact parts can be temporarily removed from the heating section, the efficiency of maintenance such as cleaning (removal of oil, etc.) of the contact parts can be significantly improved.

[0034] The filament processing machine of the 15th invention is characterized by comprising: a heating device of any of the inventions of the 1st to 14th inventions; a filament deformation inducing device for inducing deformation of the filament; and a filament conveying device configured to convey the filament to the heating device and the filament deformation inducing device for causing the filament to travel, and configured to process the filament while causing the filament to travel.

[0035] In this invention, fluctuations in the heating temperature required for processing yarn due to external disturbances can be suppressed. Therefore, variations in the quality of the yarn processed by the yarn processing machine can be suppressed. Attached Figure Description

Detailed Implementation

[0045] Next, embodiments of the present invention will be described. Figure 1 The vertical direction of the paper is defined as the length direction of the aircraft body, and the horizontal direction is defined as the width direction. The direction orthogonal to both the length and width directions is defined as the vertical direction (up-down direction) of gravity. The length and width directions are approximately parallel to the horizontal direction.

[0046] (The overall structure of a false twisting processing machine)

[0047] First, refer to Figure 1 as well as Figure 2The overall configuration of the false twisting processing machine 1 (the thread processing machine of the present invention) used for the method of manufacturing processed threads in this embodiment will be described. Figure 1 This is a side view of the false twisting machine 1. Figure 2 This is a schematic diagram of the false twisting processing machine 1 unfolding along the path (silk channel) of the silk thread Y.

[0048] The false-twisting machine 1 is configured to perform false-twisting processing on a filament Y made of synthetic fibers. The filament Y is, for example, a multifilament composed of multiple filaments. Alternatively, the filament Y may be composed of a single filament. The false-twisting machine 1 includes a feeding section 2, a processing section 3, and a winding section 4. The feeding section 2 is configured to supply the filament Y. The processing section 3 is configured to pull the filament Y from the feeding section 2 and perform false-twisting processing. The winding section 4 is configured to wind the filament Y processed by the processing section 3 onto a winding bobbin Bw. Multiple components of the feeding section 2, processing section 3, and winding section 4 are arranged along the length of the machine body (see reference). Figure 2 The length direction of the machine body is the same as the travel plane of the wire Y formed by the wire channel from the wire feeding section 2 through the processing section 3 to the winding section 4. Figure 1 (The direction is perpendicular to the paper).

[0049] The feeding section 2 has a bobbin 7 that holds multiple feeding packages Ps and supplies multiple yarns Y to the processing section 3. The processing section 3 is configured to pull out multiple yarns Y from the feeding section 2 for processing. The processing section 3 is configured to have, for example, a first feeding roller 11 (the yarn conveying device of the present invention), a twist-stopping guide 12, a first heating device 13 (the heating device of the present invention), a cooling device 14, a false twisting device 15 (the yarn deformation imparting device of the present invention), a second feeding roller 16, a winding device 17, a third feeding roller 18, a second heating device 19, and a fourth feeding roller 20 arranged sequentially from the upstream side in the yarn travel direction. The winding section 4 has multiple winding devices 21. Each winding device 21 winds the yarns Y, which have been false twisted by the processing section 3, onto a winding bobbin Bw to form a wound package Pw.

[0050] The false twisting machine 1 has a main body 8 and a winding table 9 arranged at intervals in the width direction of the machine body. The main body 8 and the winding table 9 are arranged to extend with approximately the same length in the length direction of the machine body. The main body 8 and the winding table 9 are arranged to face each other in the width direction of the machine body. The false twisting machine 1 has a unit unit called a span, which includes a set of main bodies 8 and winding tables 9. In a span, each device is configured to simultaneously perform false twisting on multiple yarns Y that are running side by side in the length direction of the machine body. The spans of the false twisting machine 1 are arranged symmetrically on the left and right sides of the paper surface with the center line C of the main body 8 in the width direction of the machine body as the axis of symmetry (the main body 8 is shared by the left and right spans). In addition, multiple spans are arranged in the length direction of the machine body.

[0051] (Composition of the machining department)

[0052] Reference Figure 1 as well as Figure 2 The configuration of the processing section 3 will be described. The first feed roller 11 is configured to unwind the yarn Y from the feed package Ps installed in the feed section 2 and feed it to the first heating device 13. Figure 2 As shown, the first feed roller 11 is configured, for example, to feed one yarn Y to the first heating device 13. Alternatively, the first feed roller 11 may also be configured to feed multiple adjacent yarns Y downstream in the yarn travel direction. The anti-twist guide 12 is configured such that the twist added to the yarn Y by the false twisting device 15 does not propagate to a position upstream in the yarn travel direction than the anti-twist guide 12.

[0053] The first heating device 13 is configured to heat the yarn Y fed from the first feed roller 11. For example... Figure 2 As shown, the first heating device 13 is configured, for example, to heat two wires Y. A more detailed description of the configuration of the first heating device 13 will be given later.

[0054] The cooling device 14 is configured to cool the filament Y after it has been heated by the first heating device 13. For example... Figure 2 As shown, the cooling device 14 is configured, for example, to cool one yarn Y. Alternatively, the cooling device 14 may be configured to cool multiple yarns Y simultaneously. The false twisting device 15 is disposed downstream of the cooling device 14 in the yarn travel direction and is configured to twist the yarn Y. The false twisting device 15 is, for example, a so-called disc friction type false twisting device, but is not limited thereto. The second feed roller 16 is configured to convey the yarn Y processed by the false twisting device 15 to the winding device 17. The conveying speed of the second feed roller 16 to the yarn Y is faster than the conveying speed of the first feed roller 11 to the yarn Y. As a result, the yarn Y is stretched and false twisted between the first feed roller 11 and the second feed roller 16.

[0055] The interlacing device 17 is configured to interlac the yarn Y. The interlacing device 17, for example, has a known interlacing nozzle that interlacs the yarn Y by means of airflow.

[0056] The third feed roller 18 is configured to feed the yarn Y, which is traveling downstream of the yarn travel direction in the cross-linking device 17, to the second heating device 19. For example... Figure 2As shown, the third feed roller 18 is configured, for example, to feed one yarn Y to the second heating device 19. Alternatively, the third feed roller 18 may be configured to feed multiple adjacent yarns Y downstream in the yarn travel direction. Furthermore, the feeding speed of the yarn Y by the third feed roller 18 is slower than the feeding speed of the yarn Y by the second feed roller 16. Therefore, the yarn Y is slack between the second feed roller 16 and the third feed roller 18. The second heating device 19 is configured to heat the yarn Y fed from the third feed roller 18. The second heating device 19 extends vertically, with one device provided across one span. The fourth feed roller 20 is configured to feed the yarn Y heated by the second heating device 19 to the winding device 21. Figure 2 As shown, the fourth feed roller 20 is configured, for example, to feed one yarn Y to the winding device 21. Alternatively, the fourth feed roller 20 may be configured to feed multiple adjacent yarns Y downstream in the yarn travel direction. The feed speed of the fourth feed roller 20 to the yarn Y is slower than the feed speed of the third feed roller 18 to the yarn Y. Therefore, the yarn Y is slack between the third feed roller 18 and the fourth feed roller 20.

[0057] In the processing section 3 configured as described above, the stretched yarn Y between the first feed roller 11 and the second feed roller 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the anti-twist guide 12, but not to a position upstream of the anti-twist guide 12 in the yarn travel direction. After being heat-fixed by the first heating device 13, the stretched and twisted yarn Y is cooled by the cooling device 14. Downstream of the false twisting device 15 in the yarn travel direction, the yarn Y is untwisted, but through the aforementioned heat fixation, the yarn Y is maintained in a false twisted wavy state (i.e., the curl of the yarn Y is maintained).

[0058] The false-twisted yarn Y is relaxed between the second feed roller 16 and the third feed roller 18, and then guided downstream in the yarn travel direction by the winding device 17, either by winding or without winding. Next, the yarn Y is relaxed between the third feed roller 18 and the fourth feed roller 20, and then heat-treated by the second heating device 19. Finally, the yarn Y fed from the fourth feed roller 20 is wound by the winding device 21.

[0059] (Composition of the winding section)

[0060] Reference Figure 2The configuration of the winding section 4 will be described. The winding section 4 has multiple winding devices 21. Each winding device 21 is configured to wind a yarn Y in a winding bobbin Bw. The winding device 21 has a fulcrum guide 41, a traverse device 42, and a cradle 43. The fulcrum guide 41 is a guide that serves as a fulcrum when the yarn Y moves laterally. The traverse device 42 is configured to move the yarn Y laterally via the traverse guide 45. The cradle 43 is configured to support the winding bobbin Bw so that it can rotate freely. A contact roller 46 is arranged near the cradle 43. The contact roller 46 contacts the surface of the wound package Pw and applies contact pressure. In the winding section 4 configured as described above, the yarn Y fed from the fourth feed roller 20 is wound by each winding device 21 onto the winding bobbin Bw to form a wound package Pw.

[0061] (First heating device)

[0062] Next, refer to Figure 3 Sections (a) to (d) provide a more specific description of the configuration of the first heating device 13. Figure 3 (a) is a view of the first heating device 13 as seen from the length of the body, and the first heating device 13 is shown in the direction of its extension (the first direction described later) towards the left and right sides of the paper. Figure 3 (b) is Figure 3 (a) is a cross-sectional view along the Ab-Ab line. Figure 3 (c) is Figure 3 (b) is the Ac-Ac line section view. Figure 3 (d) is Figure 3 (b) is a cross-sectional view along the Ad-Ad line. The direction orthogonal to both the length direction and the first direction of the fuselage is defined as the height direction (refer to...). Figure 3 (b)). In Figure 3 In (a) to (d), the upper side of the paper is set as one side in the height direction, and the lower side of the paper is set as the other side in the height direction.

[0063] The first heating device 13 is configured to heat the traveling thread Y. In this embodiment, the first heating device 13 is configured to heat two threads Y (threads Ya and Yb). The first heating device 13 extends along a predetermined first direction orthogonal to the length direction of the machine body (see reference). Figure 3 (a) etc.). The first heating device 13 has a heat source 51 and a heating section 52. The first heating device 13 simultaneously heats the traveling threads Ya and Yb by means of the heating section 52 heated by the heat source 51.

[0064] Heat source 51, for example, is a known armored heater (electric heater). An armored heater is a device having heating wire (e.g., a coil) and a tube surrounding the heating wire. The armored heater generates Joule heating when an electric current flows through the heating wire. Heat source 51 extends along a first direction (see reference). Figure 3 (c)). Heat source 51 is, for example, approximately circular in a cross-section orthogonal to the first direction (see reference). Figure 3 (b)), but not limited to this. Heat source 51 and control device 100 for controlling heating temperature (temperature of heating unit 52) ​​(see reference). Figure 3 (c) Electrical connection. The control device 100 is configured to set the heating temperature of the first heating device 13. The control device 100 controls the first heating device 13 based on the set heating temperature value. For example, the control device 100 may also control the first heating device 13 by taking into account the set heating temperature and the detection result of a temperature sensor (not shown) that detects the actual temperature of the heating unit 52.

[0065] The heating element 52 is configured to be heated by heat generated by the heat source 51. The heating element 52 extends along the heat source 51 in a first direction (see reference). Figure 3 (c)). The heating section 52 has at least one thread travel space S extending along the first direction for the thread Y to travel (see reference). Figure 3 (b) and (d)). In this embodiment, as Figure 3 As shown in (b), two thread travel spaces S (thread travel spaces Sa, Sb) are formed where two threads Ya and Yb travel respectively. The thread Ya traveling in thread travel space Sa and the thread Yb traveling in thread travel space Sb are heated by a heating unit 52 heated by a heat source 51. A more detailed description of the heating unit 52 will be provided later.

[0066] Here, generally, in order to reliably suppress temperature fluctuations in the heating unit 52 caused by external disturbances (e.g., a sudden influx of external gas into the heating unit 52), it is sufficient to make the heat capacity of the components constituting the heating unit 52 very large. However, in this case, the first heating device 13 may become very large. Therefore, considering the balance between suppressing the large size of the first heating device 13 and suppressing temperature fluctuations caused by external disturbances, the heating unit 52 is generally designed to have a certain heat capacity. However, in such a configuration, if the temperature of the heating unit 52 decreases due to external disturbances, the temperature of the wire travel space S and / or the components forming the wire travel space S (hereinafter referred to as the wire travel space S, etc.) also decreases. In this case, it may take time to return the temperature of the heating unit 52 and the wire travel space S, etc., to the set temperature. Therefore, in order to suppress the temperature drop of the thread travel space S and the like caused by external interference, and to enable the thread travel space S and the like to heat up rapidly even if the temperature drops, the first heating device 13 also has the following configuration.

[0067] (Detailed configuration of the first heating device)

[0068] Reference Figure 3 (a)~ Figure 5 The detailed configuration of the first heating device 13 will be described. Figure 4 yes Figure 3 Enlarged view of (b). Figure 5 This is a table showing the physical properties of the materials constituting the first heating element 53 (described later) and the materials constituting the second heating element 54. Figure 4 In the middle, the left side of the paper is set as one side along the length of the machine body, and the right side of the paper is set as the other side along the length of the machine body.

[0069] like Figure 3 (b) and Figure 4 As shown, the heating unit 52 includes, for example, two first heating elements 53, two second heating elements 54, and two contact blocks 55 (contact elements of the present invention). The two first heating elements 53 include first heating elements 53a and 53b. The two second heating elements 54 include second heating elements 54a and 54b. The two contact blocks 55 include contact blocks 55a and 55b. The first heating elements 53a, second heating elements 54a, and contact blocks 55a are for heating thread Ya. The first heating elements 53b, second heating elements 54b, and contact blocks 55b are for heating thread Yb. The elements for heating thread Ya and the elements for heating thread Yb are, for example, positioned on opposite sides of each other in the length direction of the machine body, separated by a heat source 51.

[0070] The components used for heating the wire Ya will be described. The first heating element 53a is a long strip extending along the heat source 51 in the first direction. The material constituting the first heating element 53a (the first material) is, for example, a metallic material with a high volumetric specific heat, such as brass. Volumetric specific heat is the value obtained by multiplying the specific heat (heat capacity per unit mass) of a material by the density (mass per unit volume) of that material. Figure 4 As shown, the first heating element 53a has a generally L-shaped cross-section, for example, orthogonal to the first direction. However, the shape of the first heating element 53a is not limited to this. The first heating element 53a is disposed on one side of the heat source 51 along its length. The first heating element 53a is disposed, for example, separately from the heat source 51.

[0071] The second heating element 54a is the same as the first heating element 53a, and is a long strip extending along the heat source 51 in the first direction. The second heating element 54a is made of a second material (details will be described later) with a volumetric specific heat smaller than that of the first material. Figure 4 As shown, the second heating element 54a has a generally rectangular shape in cross-section orthogonal to the first direction. The second heating element 54a is disposed on one side of the heat source 51 along its length. The second heating element 54a is configured to contact the heat source 51. Furthermore, the second heating element 54a is configured to contact the first heating element 53a. In a cross-section orthogonal to the first direction, the second heating element 54a, together with the second heating element 54b, surrounds the heat source 51. The second heating element 54a is disposed, for example, between the heat source 51 and the first heating element 53a in the length direction of the body. A more detailed configuration of the second heating element 54a will be described later.

[0072] The second heating element 54a, for example, forms an inverted U-shaped slit 56 (slit 56a) together with the first heating element 53a. The slit 56a opens on the other side in the height direction. A contact block 55a is housed within the slit 56a. The slit 56a functions as a storage space for the contact block 55a and also as a thread travel space Sa for the thread Ya to travel through. In other words, in this embodiment, the second heating element 54a and the first heating element 53a together form the thread travel space Sa.

[0073] Contact block 55a is, for example, a long strip component made of SUS. Contact block 55a extends at least along a first direction. Contact block 55a is, for example, machined by cutting. Contact block 55a is disposed within the wire travel space S (wire travel space Sa) in which the wire Ya travels. Contact block 55a has a contact surface 57 (contact surface 57a) that contacts the wire Ya and is at least on the other side in the height direction. In other words, the first heating element 53a and the second heating element 54a are configured not to contact the traveling wire Ya (i.e., separated from the traveling wire Ya) (see reference). Figure 4 The contact surface 57a extends at least along the first direction (see reference). Figure 3 (d)). The contact surface 57a, for example, curves gently in a roughly U-shape in a section orthogonal to the length direction of the fuselage (see reference). Figure 3 (d) The contact block 55a is embedded in the slit 56a. That is, the contact block 55a contacts at least one of the first heating element 53a and the second heating element 54a. The contact block 55a may contact at least the second heating element 54a. More precisely, the contact block 55a is shorter than the slit 56a in the length direction of the body, for example, by 0.1 mm to 0.5 mm. Therefore, a small gap can be formed between the contact block 55a and the first heating element 53a or the second heating element 54a in the length direction of the body. Most preferably, the contact block 55a contacts the second heating element 54a along its entire length in the first direction. The contact block 55a is heated by the heat transferred via the first heating element 53a and the second heating element 54a.

[0074] Furthermore, the components used for heating the wire Yb will be described. The first heating element 53b is identical to the first heating element 53a and is made of a first material. The first heating element 53b is disposed on the opposite side of the heat source 51 along its length. The first heating element 53b is disposed, for example, separately from the heat source 51. The second heating element 54b is identical to the second heating element 54a and is made of a second material. The second heating element 54b is disposed on the opposite side of the heat source 51 along its length. The second heating element 54b is configured to contact the heat source 51. Furthermore, the second heating element 54b is configured to contact the first heating element 53b. The second heating element 54b, together with the second heating element 54a, is sandwiched between the first heating element 53a and the first heating element 53b, for example, along its length. The second heating element 54b, for example, together with the first heating element 53b, forms a slit 56b identical to the slit 56a. A contact block 55b is housed within the slit 56b. The slit 56b functions as a storage space for the contact block 55b and also as a thread travel space Sb for the thread Yb to travel. The contact block 55b is, for example, a long strip component made of SUS. The contact block 55b is machined in the same way as the contact block 55a. The contact block 55b has the same contact surface 57b as the contact surface 57a for making the thread Yb come into contact. In other words, the first heating element 53b and the second heating element 54b are configured not to come into contact with the traveling thread Yb (i.e., to be separated from the traveling thread Yb) (see reference). Figure 4 The contact block 55b is embedded in the slit 56b. That is, the contact block 55b is in contact with at least one of the first heating element 53b and the second heating element 54b.

[0075] (Details of the second heating element)

[0076] Next, refer to Figure 3 (b) and Figure 4 A more detailed description of the configuration of the second heating element 54 (here, referred to as the second heating element 54a) will be given. The second heating element 54a is, for example, configured to be sandwiched between the heat source 51 and the wire travel space Sa in a cross-section orthogonal to the first direction. "Between the heat source 51 and the wire travel space Sa" is defined, for example, as follows: That is, it is possible to sandwich the heat source 51 between the heat source 51 and the wire travel space Sa in a predetermined cross-section orthogonal to the first direction (e.g., referring to...). Figure 4 In the contact surface 57a, the side furthest in the height direction (that is, in) Figure 4 In the cross-section shown, multiple imaginary line segments (e.g., line segments L1, L2, L3, etc.) are depicted in a manner connecting the point Pa (farthest from the entrance of the slit 56a in the height direction) to the outer surface 51s of the heat source 51. When at least one of these line segments passes through the second heating element 54a, it is defined as "the second heating element 54a is disposed between the heat source 51 and the thread travel space Sa". The same definition can also be applied to "between the heat source 51 and the thread travel space Sb".

[0077] The second heating element 54 may also contact the heat source 51, the first heating element 53, and the contact block 55 as in this embodiment. Furthermore, the ratio of the heat capacity of the second heating element 54 to the heat capacity of the first heating element 53 may be, for example, 20% or more and 40% or less.

[0078] The details of the second material constituting the second heating element 54 will be explained. As described above, the volumetric specific heat of the second material is lower than that of the first material. More specifically, a C / C composite material (carbon fiber reinforced carbon composite material) is used as the second material. A C / C composite material is a composite material of carbon fiber and graphite. For example, known pitch-based carbon fiber is used as the carbon fiber. Figure 5 As shown, in this embodiment, the volumetric specific heat of the brass used as the first material is, for example, 3.35 J / (cm³) at 20°C. 3 ·K). In contrast, the volumetric specific heat of the C / C composite material used as the second material is, for example, 1.12 J / (cm³) at 20 °C. 3 (·K). Therefore, the second heating element 54 can be heated more rapidly than the first heating element 53. That is, if the temperature of the yarn travel space S, etc., decreases due to external interference, the second heating element 54 can rapidly heat up the yarn travel space S, etc. Therefore, even if the temperature of the yarn travel space S, etc., decreases, the temperature of the yarn travel space S, etc., can be rapidly increased.

[0079] Furthermore, in this embodiment, the C / C composite material used as the second material has an orientation. More specifically, most of the carbon fibers are oriented along a predetermined X direction. The X direction is, for example, the first direction in this embodiment. Therefore, the thermal conductivity of the second material is anisotropic. Figure 5 As shown, the thermal conductivity of the C / C composite material in the first direction (X direction) is, for example, 180 W / (m·K) at 20°C. On the other hand, the thermal conductivity of the C / C composite material in the Y direction (e.g., the length direction, height direction, etc.) orthogonal to the X direction is, for example, 80 W / (m·K) at 20°C, which is lower than the thermal conductivity in the X direction. Furthermore, in this embodiment, the thermal conductivity of the C / C composite material in at least the first direction is higher than that of brass (e.g., 60 W / (m·K) at 20°C). By using a second heating element 54 made of such a second material, the heating temperature in the first direction can be homogenized.

[0080] Furthermore, in this embodiment, the thermal conductivity of the C / C composite material (80 W / (m·K) mentioned above) is also higher than that of brass (60 W / (m·K) mentioned above) in any direction orthogonal to the first direction. In other words, it becomes as follows. (Refer to the cross-sectional view orthogonal to the first direction). Figure 4 In this design, for example, the direction in which the line segment L3 connecting point Pa and the outer surface 51s of the heat source 51 with the shortest distance extends is defined as the second direction. Line segment L3 corresponds to the "prescribed imaginary straight line from the heat source toward the thread travel space" of this invention. With this configuration, heat can be rapidly transferred from the heat source 51 toward the thread travel space Sa, etc. Therefore, the thread travel space Sa, etc., can be rapidly heated. Similarly, the thread travel space Sb, etc., can also be rapidly heated.

[0081] Furthermore, in this embodiment, the first heating device 13 is particularly preferably heated while the traveling thread Y is in contact with the contact surface 57, with the heating temperature set to a predetermined temperature of 230°C to 350°C. Within this temperature range, the heating efficiency of the thread Y can be improved compared to conventional heating devices (not shown). Of course, the heating temperature of the first heating device 13 can be set to a temperature lower than 230°C or a temperature higher than 350°C.

[0082] As described above, a material with a relatively high volumetric specific heat is used as the first material constituting the first heating element 53, thereby suppressing the temperature drop of the heating element 52 caused by external interference to a certain extent. Furthermore, in this embodiment, the second heating element 54, which has a lower volumetric specific heat, can heat up more rapidly than the first heating element 53. As a result, the thread travel space S, etc., can be rapidly heated via the second heating element 54 disposed between the heat source 51 and the thread travel space S. Therefore, through such rapid heating, the temperature drop of the thread travel space S, etc., caused by external interference can be suppressed. In addition, even if the temperature of the thread travel space S, etc., drops due to external interference, the thread travel space S, etc., can be rapidly heated up.

[0083] Furthermore, the second heating element 54 is in contact with the heat source 51. This allows heat generated by the heat source 51 to be rapidly transferred to the second heating element 54, thus enabling the second heating element 54 to be effectively heated.

[0084] Furthermore, the second heating element 54, together with the first heating element 53, forms the yarn travel space S. Therefore, the yarn travel space S can be effectively heated by the second heating element 54.

[0085] Furthermore, the second heating element 54 is in contact with the first heating element 53. Therefore, the first heating element 53 can be rapidly heated via the second heating element 54. In addition, in this case, for example, compared with the case where the heat source (not shown) for heating the first heating element 53 is separated from the heat source 51 and the second heating element 54 is separately configured from the first heating element 53, the increase in manufacturing cost can be suppressed.

[0086] Furthermore, the ratio of the heat capacity of the second heating element 54 to the heat capacity of the first heating element 53 is more than 20% and less than 40%. Thus, the heat capacity of the second heating element 54 is neither too large nor too small compared to the heat capacity of the first heating element 53. Consequently, the heating element 52 can be enhanced to a certain extent relative to external disturbances, and the wire travel space S can be rapidly heated.

[0087] Furthermore, the second material constituting the second heating element 54 includes a fibrous material. This allows the thermal conductivity of the second material to be anisotropic. Consequently, heat can be transferred very rapidly in the direction in which heat is particularly desired.

[0088] Furthermore, the aforementioned fiber material is carbon fiber. Carbon fiber is a lightweight material with high thermal conductivity. Therefore, heat can be transferred very quickly in the direction in which heat is to be transferred. In addition, the first heating device 13 can be made lighter.

[0089] Furthermore, the aforementioned carbon fiber is a pitch-based fiber. Pitch-based carbon fibers and PAN-based carbon fibers are generally known as carbon fibers. Generally, pitch-based carbon fibers have a higher thermal conductivity than PAN-based carbon fibers. Therefore, by using pitch-based carbon fibers as the carbon fiber, the thermal conductivity of the second material can be further improved.

[0090] Furthermore, by using a composite material of carbon fiber and graphite as the second material, the thermal conductivity of the second material can be further improved.

[0091] Furthermore, the second material has a higher thermal conductivity in the first direction compared to the first material. Therefore, heat can be rapidly transferred in the first direction via the second heating element 54. Consequently, temperature deviations in the filament travel space S, etc., in the first direction can be suppressed.

[0092] Furthermore, the second material has a higher thermal conductivity in the second direction compared to the first material. Therefore, heat can be rapidly transferred from the heat source 51 to the thread travel space S via the second heating element 54. Consequently, the thread travel space S can be rapidly heated.

[0093] Furthermore, the heating unit 52 has a contact block 55. In the configuration where the contact block 55 is provided as in this embodiment, the contact block 55 can be effectively heated by rapidly heating the second heating member 54.

[0094] Furthermore, the contact block 55 is in contact with the second heating element 54. Therefore, through heat conduction between the contact block 55 and the rapidly heating second heating element 54, the contact block 55 can be effectively heated.

[0095] Furthermore, by performing false twisting processing in the false twisting processing machine 1 equipped with the first heating device 13, it is possible to suppress fluctuations in the heating temperature required for processing the yarn Y due to external disturbances. Therefore, it is possible to suppress fluctuations in the quality of the yarn Y processed by the false twisting processing machine 1.

[0096] Next, variations of the above-described embodiments will be described. However, for components having the same structure as those in the above-described embodiments, the same symbols will be used and descriptions will be omitted as appropriate.

[0097] (1) In the above embodiment, the carbon fibers contained in the C / C composite material, which is the second material, are oriented along the first direction. However, this is not a limitation. For example, in the second heating member 54a, the carbon fibers may also be oriented along the second direction. Furthermore, in the second heating member 54b, the carbon fibers may also be oriented along a direction from the heat source 51 toward the filament travel space Sb, etc. In this case, heat can be transferred very rapidly from the heat source 51 to the filament travel space S, etc.

[0098] (2) In the embodiments described above, the carbon fiber included in the second material is pitch-based fiber. However, it is not limited to this. For example, the carbon fiber may also be a known PAN-based carbon fiber.

[0099] (3) In the embodiments described above, the second material is a C / C composite material (a composite material of carbon fiber and graphite). However, it is not limited to this. The second material may also be a composite material of carbon fiber and resin (e.g., epoxy resin), namely CFRP (carbon fiber reinforced plastic). CFRP is cheaper than C / C composite material, therefore, by using CFRP as the second material, the increase in manufacturing cost of the first heating device 13 can be suppressed.

[0100] (4) In the embodiments described above, carbon fiber is included as the fiber material in the second material. However, this is not a limitation. Materials other than carbon fiber may also be used as the fiber material.

[0101] (5) In the embodiments described above, the carbon fibers contained in the C / C composite material are oriented along a specified X direction. However, this is not a limitation. The carbon fibers may not be oriented along a specific direction (i.e., they may be oriented randomly).

[0102] (6) In the embodiments described above, the thermal conductivity of the second material is higher than that of the first material in both the first and second directions. However, this is not a limitation. The thermal conductivity of the second material may, for example, be higher than that of the first material only in one of the first and second directions. Alternatively, the thermal conductivity of the second material may be lower than that of the first material. The second material may also simply have the characteristic of having a smaller volumetric specific heat than the first material. As an example, the first heating element 53 may, for example, be made of aluminum. Figure 6 As shown in (a), the volumetric specific heat of aluminum (material 1) at 20 °C is 2.43 J / (cm³). 3 In this case, the volumetric specific heat of the C / C composite (material 2) is less than that of aluminum. On the other hand, the thermal conductivity of aluminum (material 1) is 204 W / (m·K) at 20°C, which is higher than that of the C / C composite (material 2) in any direction.

[0103] (7) The combination of material 1 and material 2 is not limited to the above. For example, such as... Figure 6As shown in (b), the first material can be brass and the second material can be aluminum. In this case, the volumetric specific heat of the second material is lower than that of the first material, and the thermal conductivity of the second material is higher than that of the first material. In addition, aluminum has superior heat resistance compared to C / C composite materials. When a material with such excellent heat resistance is applied to the heating part 52, a higher heating temperature can be set. In this case, the first heating device 13 can be, for example, a non-contact heating device (not shown) as described in Japanese Patent Application Publication No. 2002-146640. In the non-contact heating device, instead of the contact block 55, a plurality of wire guides (not shown) are provided and arranged separately from each other in the first direction. Each wire guide is not a component for directly heating the wire Y, but only for guiding the wire Y. In the non-contact heating device, the wire Y is mainly heated by the heated air in the wire travel space S.

[0104] (8) In the embodiments described above, the first heating device 13 is configured to heat two threads Y. However, it is not limited to this. A first heating device (not shown) capable of heating three or more threads Y may also be provided. Or, for example, as... Figure 7 As shown, a first heating device 13A can also be configured to heat one wire Y. The heating section 52A of the first heating device 13A can also be configured to be connected to the heating section 52 (see reference 52). Figure 4 Compared to other methods, for example, only the first heating element 53b and the contact block 55b are removed. Alternatively, in the first heating device 13A, a first heating element 61 made of a first material may be provided instead of the second heating element 54b.

[0105] (9) In the embodiments described above, the second heating element 54 is in contact with the heat source 51 and the contact block 55. However, this is not a limitation. The second heating element 54 may be in contact with only one of the heat source 51 and the contact block 55, or it may not be in contact with either the heat source 51 or the contact block 55. In this case, the first heating element 53 may be configured to be in contact with only the heat source 51 and / or the contact block 55. Furthermore, in the embodiments described above, the second heating element 54 is in contact with the first heating element 53, but this is not a limitation. For example, the heat source (not shown) for heating the first heating element 53 may be provided separately from the heat source 51, and the second heating element 54 may be configured separately from the first heating element 53.

[0106] Alternatively, for example, only a portion of the contact block 55 in the first direction may contact the second heating element 54. However, in this case, the heating efficiency of the contact block 55 is lower compared to a configuration where the contact block 55 contacts the second heating element 54 along its entire length in the first direction.

[0107] Alternatively, neither the first heating element 53 nor the second heating element 54 may contact the contact block 55. However, in this case, the heating efficiency of the contact block 55 is low. Furthermore, the heating efficiency of the contact block 55 is high in the following order: As a first configuration, the heating efficiency is highest in the configuration where at least the second heating element 54 contacts the contact block 55. As a second configuration, the heating efficiency is second highest in the configuration where only the first heating element 53 contacts the contact block 55. As a third configuration, the heating efficiency is lowest in the configuration where neither the first heating element 53 nor the second heating element 54 contacts the contact block 55. If two or more configurations from the first to third configurations are inadvertently mixed among the multiple heating elements 52, the heating efficiency of the contact block 55 may deviate among the multiple heating elements 52. Therefore, it is preferable to unify the multiple heating elements 52 and the multiple first heating devices 13 into any one of the first to third configurations as much as possible.

[0108] (10) In the embodiments described above, the ratio of the heat capacity of the second heating element 54 to the heat capacity of the first heating element 53 is 20% to 40%. However, this is not a limitation. The ratio may be less than 20% or greater than 40%.

[0109] (11) In the embodiments described above, the contact surface 57 is curved in a cross-section orthogonal to the length direction of the body. However, this is not a limitation. The contact surface 57 may also be approximately straight in a cross-section orthogonal to the length direction of the body.

[0110] (12) In the embodiments described above, the first heating device 13 and the first heating device 13A have a contact block 55. However, this is not a limitation. Instead of the contact block 55, an unshown SUS plate that is sheet metal-machined in an inverted U-shape in a cross-section orthogonal to the first direction may be provided as the contact member (for example, see Japanese Patent Application Publication No. 2002-194631).

[0111] (13) The contact component (contact block 55 or the SUS plate mentioned above) may also be configured to be detachable from the heating unit 52. As a result, the contact component can be temporarily removed from the heating unit 52, thereby greatly improving the efficiency of maintenance such as cleaning of the contact component.

[0112] (14) In the embodiments described above, the slit 56 is formed by both the first heating element 53 and the second heating element 54. However, it is not limited to this. The slit 56 may also be formed by only one of the first heating element 53 and the second heating element 54. That is, the first heating element 53 may form the entire slit 56. Alternatively, the second heating element 54 may also form the entire slit 56.

[0113] (15) In the embodiments described above, the heat source 51 has an armored heater. However, it is not limited to this. Instead of the heat source 51, a heat source (not shown) configured to heat the heating unit 52 by means of a heat medium may be provided.

[0114] (16) The configuration of the first heating device 13 described above can also be applied to the second heating device 19. Furthermore, the first heating device 13 described above is not limited to the false twisting machine 1, and can also be applied to known false twisting machines (not shown) having other configurations. For example, the present invention can also be applied to the false twisting machine (not shown) described in Japanese Patent Application Publication No. 2009-74219. This false twisting mechanism is capable of twisting two threads together to form one thread. This false twisting mechanism is capable of winding either the twisted thread or the two untwisted threads onto a single cradle. As an example, the present invention can be applied to such a false twisting machine. Alternatively, in addition to being applied to false twisting machines, the first heating device 13 can also be applied to, for example, a known gas processing machine (not shown), a thread processing machine that processes while the thread (not shown) is traveling.
