Description

Technical Field

[0001] This invention relates to a heating device for heating wires. Background Technology

[0002] Conventionally, in false twisting machines, contact heating devices are known that heat the yarn by bringing it into contact with a high-temperature splicing section. For example, Patent Document 1 describes a contact heating device (the secondary heater of Patent Document 1) that includes a heat source, a splicing section (the heat transfer body of Patent Document 1), and a space for the yarn to travel. A splicing surface is formed at the splicing section to contact the traveling yarn. The splicing surface extends along the yarn's travel direction, and heat generated from the heat source is transferred through the splicing section and supplied to the yarn from the splicing surface.

[0003] In the heating device of Patent Document 1, a wire guide is provided at the wire inlet of the wire travel space. The wire introduced from the wire inlet into the wire travel space is guided by the wire guide in such a way that it contacts the wire receiving surface of the wire receiving part.

[0004] Patent Document 1: Japanese Patent Application Publication No. 9-296330

[0005] Depending on the placement of the wire guide, if the contact length between the wire guided by the wire guide and the receiving surface becomes too long or too short, it may prevent proper heating of the wire, leading to a decrease in wire quality. Therefore, the wire guide should be placed in a position that allows for proper contact between the wire and the receiving surface.

[0006] However, even slight offsets in the guide wire's position can cause significant variations in the wire's contact length. Therefore, the guide wire must be precisely positioned to ensure an appropriate contact length. However, in typical heating devices, the guide wire is usually housed within the heating device's frame. This results in multiple components sandwiched between the guide wire and the wire connector, making it difficult to precisely position the guide wire relative to the connector due to manufacturing and assembly errors in each component. While using specialized clamps to adjust the guide wire's position is an option, it is extremely cumbersome for the operator. Summary of the Invention

[0007] The purpose of this invention is to provide a heating device that can easily and accurately configure the wire guide so that the contact length between the wire and the receiving surface is appropriate.

[0008] The heating device of the present invention is characterized by comprising: a heat source; a wire receiving portion heated by the heat source and having a wire traveling space extending along the wire traveling direction and a wire receiving surface capable of contacting the wire traveling in the wire traveling space; and at least one wire guide for guiding the wire traveling in the wire traveling space, the wire guide being mounted on the wire receiving portion.

[0009] According to the present invention, the wire guide is mounted on the wire receiving portion. Therefore, the wire guide and the wire receiving portion are integrally configured, eliminating or significantly reducing the number of components sandwiched between the wire guide and the wire receiving portion. Thus, the effects of manufacturing and assembly errors of other components can be suppressed, and the wire guide can be easily and precisely configured to ensure an appropriate contact length between the wire and the wire receiving surface.

[0010] In the heating device of the present invention, it is preferable that the above-mentioned wire guide is directly installed on the wire receiving part.

[0011] According to the present invention, the component sandwiched between the wire guide and the wire connector can be eliminated. This eliminates the influence of manufacturing and assembly errors of other components, allowing for a more precise configuration of the wire guide to ensure an appropriate contact length between the wire and the wire connector surface.

[0012] In the heating device of the present invention, it is preferable that a positioning part is formed in the wire-connecting part, which is used to determine the position where the wire guide is installed.

[0013] According to the present invention, the position of the wire guide can be specified by the positioning part. Therefore, it is easier to position the wire guide at a position that makes the contact length between the wire and the receiving surface appropriate.

[0014] In the heating device of the present invention, it is preferable that the positioning part has a limiting part that restricts the movement of the guide wire in the direction of wire travel.

[0015] According to the present invention, it is possible to suppress a large deviation of the wire guide installed at the wire splice in the wire travel direction. Therefore, it is possible to suppress the deviation of the contact length between the wire guided by the wire guide and the wire splice surface from an appropriate length.

[0016] In the heating device of the present invention, preferably, the limiting portion is a group of wall portions formed at intervals in the direction of the wire travel, and the wire guide is disposed between the group of wall portions.

[0017] According to the present invention, the movement of the guide wire to one side and to the other side in the direction of wire travel is limited by a set of walls. Therefore, it is possible to more reliably suppress large-scale deviation of the guide wire in the direction of wire travel, and to further suppress the deviation of the contact length between the wire guided by the guide wire and the contact surface from the appropriate length.

[0018] In the heating device of the present invention, it is preferable that the interval between the filaments traveling in the direction of the aforementioned group of walls is greater than the maximum dimension of the filaments traveling in the direction of the aforementioned guide.

[0019] According to the present invention, even if the maximum dimension of the wire travel direction of the wire guide deviates due to manufacturing errors, the wire guide can be reliably configured between a set of wall portions.

[0020] In the heating device of the present invention, preferably, the positioning part has an abutting portion for the guide wire to abut, and the heating device further includes a pressing part for pressing the guide wire against the abutting portion, wherein the pressing part presses the guide wire against the abutting portion in a direction opposite to a first direction in which the wire is pressed against the wire receiving surface.

[0021] The tension of the thread acts in the first direction. Therefore, the guide wire in contact with the thread tends to separate from the contact portion due to the tension of the thread. According to the present invention, by pressing the guide wire against the contact portion in the opposite direction by the pressing part, separation of the guide wire from the contact portion can be suppressed. Thus, the thread can be reliably guided through the guide wire.

[0022] In the heating device of the present invention, it is preferable that the pressing part is a leaf spring.

[0023] According to the present invention, the guide wire can be separated from the abutment portion by a simple configuration.

[0024] In the heating device of the present invention, it is preferable that the guide wire is positioned outside the end point of the wire traveling in the direction of the wire on the receiving surface.

[0025] According to the present invention, the thread is guided by a guide located on the outer side of the end point of the thread travel direction compared to the contact surface, thus ensuring the longest possible contact length between the thread and the contact surface. This prevents the thread from becoming insufficiently heated.

[0026] In the heating device of the present invention, preferably, the wire guide includes: a first wire guide disposed at a position outside the end point on one side of the wire traveling direction of the wire receiving surface; and a second wire guide disposed at a position outside the end point on the other side of the wire traveling direction of the wire receiving surface.

[0027] According to the present invention, the thread is guided by a first guide located on the outer side of the end point on one side of the thread travel direction relative to the contact surface and a second guide located on the outer side of the end point on the other side of the thread travel direction relative to the contact surface. Therefore, the contact length between the thread and the contact surface can be ensured more reliably and for a longer period. As a result, insufficient heating of the thread can be further suppressed.

[0028] In the heating device of the present invention, preferably, the wire receiving surface has a curved shape that protrudes toward the side where the wire travel space is located in the cross section along the wire travel direction, and when viewed from an orthogonal direction orthogonal to the cross section along the wire travel direction, the contact point between the wire guide and the wire is located at a position closer to the side where the wire travel space is located than the tangent at the end point of the wire receiving surface in the wire travel direction.

[0029] The thread is prone to wear due to friction caused by contact with the end of the receiving surface. According to the present invention, the thread guided by the thread guide floats from the end. Therefore, the thread can contact the receiving surface midway. This avoids contact between the thread guided by the thread guide and the end of the receiving surface, thus suppressing thread wear.

[0030] In the heating device of the present invention, it is preferable that the wire guide can be detached from the wire connector.

[0031] According to the present invention, it is possible to easily replace the guide wire that has deteriorated due to continuous contact with the wire. Attached Figure Description

Detailed Implementation

[0042] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0043] (The overall structure of a false twisting processing machine)

[0044] Figure 1 This is a side view showing the general configuration of the false twisting processing machine 1 according to this embodiment. Hereinafter, Figure 1 The vertical direction of the paper is defined as the length direction of the aircraft, 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 roughly parallel to the horizontal direction. The above directional terms will be used appropriately in the following explanations.

[0045] The false-twisting machine 1 is configured to perform false-twisting processing on yarn Y made of synthetic fibers such as nylon (polyamide fiber). The false-twisting machine 1 includes: a yarn feeding section 2 for feeding yarn Y; a processing section 3 for performing false-twisting processing on the yarn Y supplied from the yarn feeding section 2; and a winding section 4 for winding the yarn Y processed by the processing section 3 onto a bobbin Bw. Each component of the yarn feeding section 2, processing section 3, and winding section 4 is positioned relative to the yarn travel surface of the yarn channel that connects the yarn from the yarn feeding section 2 through the processing section 3 to the winding section 4. Figure 1 (On the paper) there are multiple orthogonal bodies arranged along their length.

[0046] The yarn feeding section 2 has a bobbin holder 7 that holds multiple yarn packages Ps and supplies multiple yarns Y to the processing section 3. The processing section 3 is configured such that, starting from the upstream side in the yarn travel direction, it is sequentially arranged a first yarn feeding roller 11, a twist guide 12, a first heating device 13 (the heating device of the present invention), a cooling device 14, a false twisting device 15, a second yarn feeding roller 16, a winding device 17, a third yarn feeding roller 18, a second heating device 19, and a fourth yarn feeding roller 20. The winding section 4 uses a winding device 21 to wind the yarns Y, which have been false twisted by the processing section 3, onto a bobbin Bw to form a wound package Pw.

[0047] Furthermore, the false twisting processing 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 extend to approximately the same length in the length direction of the machine body and are arranged opposite each other. The upper part of the main body 8 and the upper part of the winding table 9 are connected by a support frame 10. The various devices constituting the processing unit 3 are mainly installed in the main body 8 and the support frame 10. The main body 8, the winding table 9, and the support frame 10 form a working space 22 for the operator to perform operations such as wire hanging on the various devices. The wire channel is formed such that the wire Y mainly travels around the working space 22.

[0048] The false twisting machine 1 has a unit unit called a span, comprising a set of main bodies 8 arranged opposite each other and a winding table 9. Within a span, each device is configured to simultaneously perform false twisting on multiple yarns Y traveling in a configuration along the length of the machine body. For example, the winding table 9 within a span has a total of 16 winding devices 21 arranged in 4 layers and 4 columns. Furthermore, in the false twisting machine 1, the span is symmetrically arranged on the paper surface about the centerline C of the main body 8 in the width direction (the main body 8 is shared in both left and right spans), and multiple spans are arranged along the length of the machine body.

[0049] (Composition of the machining department)

[0050] Next, refer to Figure 1 as well as Figure 2 The configuration of the processing unit 3 will be described. The first feed roller 11 is configured to unwind the yarn Y from the yarn feed package Ps installed in the yarn feed unit 2 and feed it to the first heating device 13. The first feed roller 11 is positioned above the winding table 9 (see reference). Figure 1 ).like 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 to the downstream side in the yarn travel direction.

[0051] The anti-twist guide 12 is used to prevent the twist applied to the yarn Y by the false twisting device 15 (described later) from propagating to the upstream side of the yarn travel direction beyond the anti-twist guide 12. The anti-twist guide 12 is located downstream of the first feed roller 11 in the yarn travel direction and upstream of the first heating device 13 in the yarn travel direction. For example, as Figure 2 As shown, the anti-twist guide 12 is provided separately relative to the multiple yarns Y supplied from the yarn supply section 2, and is arranged in a row along the length of the machine body.

[0052] The first heating device 13 is used to heat the yarn Y conveyed from the first feed roller 11 to a specified processing temperature, and is installed on the support frame 10 (see reference). Figure 1 For example, such as Figure 2 As shown, the first heating device 13 is configured to heat two wires Y. More details about the first heating device 13 will be described later.

[0053] The cooling device 14 is used to cool the yarn Y heated by the first heating device 13. The cooling device 14 is located downstream of the first heating device 13 in the yarn travel direction and upstream of the false twisting device 15 in the yarn travel direction. For example, as... Figure 2 As shown, the cooling device 14 is configured to cool one wire Y, and multiple cooling devices 14 are arranged in a row along the length of the machine body. Alternatively, the cooling device 14 may be configured to cool multiple wires Y simultaneously.

[0054] The false twisting device 15 is a device for twisting the yarn Y. The false twisting device 15 is positioned immediately downstream of the cooling device 14 in the yarn travel direction. For example, as... Figure 2 As shown, the false twisting device 15 is used to twist a single yarn Y, and multiple such devices are arranged along the length of the machine body. For example, 16 false twisting devices 15 are provided in each span.

[0055] The second feed roller 16 is a roller that feeds the yarn Y, twisted by the false twisting device 15, toward the winding device 17. The second feed roller 16 is disposed in the main body 8 downstream of the false twisting device 15 in the yarn travel direction. The feed speed of the second feed roller 16 on the yarn Y is faster than that of the first feed roller 11. Therefore, the yarn Y is stretched between the first feed roller 11 and the second feed roller 16.

[0056] The winding device 17 is a device that applies winding by spraying air onto the yarn Y. The winding device 17 is disposed in the main body 8 below the second feed roller 16.

[0057] The third feed roller 18 is a roller that feeds the yarn Y, which has been entangled by the entanglement device 17, toward the second heating device 19. The third feed roller 18 is disposed in the main body 8 below the entanglement device 17. The feed speed of the third feed roller 18 to the yarn Y is slower than the feed speed of the second feed roller 16 to the yarn Y. Therefore, the yarn Y is slack between the second feed roller 16 and the third feed roller 18.

[0058] The second heating device 19 is used to heat the yarn Y fed from the third feed roller 18. The second heating device 19 is located in the main body 8 below the third feed roller 18. Figure 1 As shown, the second heating device 19 extends vertically, with one device installed in each span. Furthermore, as... Figure 2 As shown, the second heating device 19 is configured to extend along the length of the machine body and can simultaneously heat multiple filaments Y.

[0059] The fourth feed roller 20 is used to feed the yarn Y, which has been heat-treated by the second heating device 19, toward the winding device 21. The fourth feed roller 20 is located at the lower part of the winding table 9. The feed speed of the fourth feed roller 20 to the yarn Y is slower than that of the third feed roller 18. Therefore, the yarn Y is slack between the third feed roller 18 and the fourth feed roller 20.

[0060] In the processing section 3 configured as described above, the yarn Y stretched 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 does not propagate upstream of the anti-twist guide 12 in the yarn travel direction. The yarn Y, which is stretched and twisted at the same time, is heat-set by the first heating device 13 and then cooled by the cooling device 14. Downstream of the false twisting device 15, the yarn Y is untwisted, but the heat setting mentioned above maintains the false twisted wavy state of each filament. The yarn Y, which has been false twisted by the false twisting device 15, is relaxed between the second feed roller 16 and the third feed roller 18, and is guided downstream in the yarn travel direction by the winding device 17. Furthermore, the yarn Y is relaxed between the third feed roller 18 and the fourth feed roller 20 and is heat-set by the second heating device 19. Finally, the yarn Y fed from the fourth feed roller 20 is wound by the winding device 21 to form a wound package Pw.

[0061] (Composition of the winding section)

[0062] Next, refer to Figure 2 The 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 into a bobbin Bw. The winding device 21 has a fulcrum guide 41, a traversing device 42, and a cradle 43. The fulcrum guide 41 is a guide that serves as the fulcrum when the yarn Y is traversed. The traversing device 42 is configured to traverse the yarn Y via the traversing guide 45. The cradle 43 is configured to support the 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 bobbin Bw to form a wound package Pw.

[0063] (First heating device)

[0064] Next, refer to Figures 3-8 A more specific description of the configuration of the first heating device 13 will be provided. Figure 3This diagram shows the first heating device 13 as viewed from the length of the machine body, and the first heating device 13 is shown in the direction of its extension (hereinafter, the extension direction) facing left and right on the paper. In this embodiment, the direction of the thread travel is approximately the same as the extension direction. Figure 4 yes Figure 3 Sectional view along line IV-IV. Figure 5 This is a diagram showing the first heating device 13 viewed from the extended direction. Figure 6 yes Figure 4 Sectional view along line VI-VI. Figure 7 This is a perspective view showing the portion of the wire connector 54 where the wire guide 70 is installed. Figure 8 Viewed from the length direction of the body Figure 7 The diagram shows the height direction. The direction orthogonal to both the length and extension directions of the aircraft is defined as the height direction (refer to...). Figure 3 (etc.). In Figure 3 as well as Figure 6 In this diagram, the left side of the paper is designated as one side of the extension direction, and the right side as the other side. One side of the extension direction can be, for example, the upstream side of the thread's travel direction, but is not limited to this. Figure 4 In this case, the bottom of the paper is designated as one side of the height direction, and the top of the paper is designated as the other side of the height direction.

[0065] The first heating device 13 is configured to heat the traveling thread Y. In this embodiment, the first heating device 13 is configured, for example, to heat two threads Y (see reference). Figure 4 The first heating device 13 extends along a prescribed extension direction orthogonal to the length direction of the machine body (see reference). Figure 3 (etc.). The first heating device 13 includes a heat source 51, a heating section 52, a wire guide 70, and a wire guide fixing member 90. The first heating device 13 heats two wires Y simultaneously by bringing the traveling wire Y into contact with the heating section 52 heated by the heat source 51.

[0066] Heat source 51 is, for example, a known armored heater (electric heater). An armored heater is a device having heating wires (e.g., coils) and a tube surrounding the heating wires. The armored heater generates Joule heating when an electric current flows through the heating wires. Heat source 51 extends along the extending direction (see reference). Figure 3 Heat source 51 and control device 100 for controlling heating temperature (see reference) Figure 3Electrical 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 temperature value. For example, the control device 100 may also control the first heating device 13 by taking into account the set temperature and the detection results of a temperature sensor (not shown) that detects the actual temperature of the heating unit 52. In addition to the first heating device 13, the control device 100 may also be electrically connected to the apparatus constituting the false twisting machine 1.

[0067] 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 the extending direction (see reference). Figure 3 The heating section 52, for example, has two heating elements 53 and two wire-connecting sections 54 (the wire-connecting sections of the present invention). Figure 4 As shown, the two heating elements 53 and the wire connector 54 are positioned on opposite sides of the body along its length, separated by the heat source 51. One side along the length of the body ( Figure 4 The heating element 53 and the wire-connecting part 54 (on the left side of the paper) are components used to heat the wire Y located on one side of the machine body along its length. The other side of the machine body along its length ( Figure 4 The heating element 53 and the wire connecting part 54 (on the right side of the paper) are components used to heat the wire Y located on the other side of the machine body in the length direction.

[0068] The heating element 53 is made of a metal material with a high specific heat, such as brass. The heating element 53 extends along the heat source 51 in the extending direction. Figure 4 As shown, the heating element 53 is configured to contact the heat source 51. The heating element 53 has a slit 55 extending along the extending direction. Figure 4 As shown, slit 55 is an inverted U-shaped slit in a cross-section orthogonal to the extension direction. The slit 55 opens on one side in the height direction. A wire-connecting portion 54 is housed within the slit 55.

[0069] The wire splicing portion 54 is a component that forms a wire travel space 61 extending along the wire travel direction Y. The wire splicing portion 54 is, for example, a long strip component made of SUS steel. The wire splicing portion 54 extends along the extending direction. Figure 4 As shown, the wire-connecting portion 54 has an inverted U-shape in a cross-section orthogonal to the extending direction. Figure 4 As shown, the wire connector 54 is housed within the slit 55. The wire connector 54 is fixed to the heating element 53 while in contact with it. The wire connector 54 is heated by heat transferred from the heat source 51 via the heating element 53. The wire connector 54 is configured to be detachable from the heating element 52.

[0070] The wire-connecting portion 54 has a wire-connecting surface 56 for contacting the wire Y. The wire-connecting surface 56 faces at least one side in the height direction. The wire Y traveling in the wire travel space 61 is pressed against the wire-connecting surface 56 on the other side in the height direction. In addition, the direction facing the other side in the height direction corresponds to the first direction of the present invention. The wire-connecting surface 56 is gently curved in a generally U-shape in a cross section orthogonal to the length direction of the body (see reference). Figure 6 That is, in a cross-section orthogonal to the length direction of the machine body, the wire-connecting surface 56 has a curved shape that protrudes towards the side where the wire travel space 61 is located, i.e., in the height direction. In other words, when viewed from the length direction of the machine body, the wire-connecting surface 56 forms a shape in which the two ends in the extension direction are closer to the side in the height direction than the central portion. In addition, the cross-section orthogonal to the length direction of the machine body corresponds to the cross-section along the wire travel direction of the present invention. Furthermore, the wire-connecting surface 56 is, for example, curved in an inverted U-shape in a cross-section orthogonal to the extension direction (see reference). Figure 4 ).

[0071] like Figure 6 as well as Figure 8 As shown, the endpoint 74 on one side of the extending direction of the wire-connecting surface 56 is located on the other side relative to the end on one side of the extending direction of the first heating device 13. The endpoint 75 on the other side of the extending direction of the wire-connecting surface 56 is located on the other side relative to the end on the other side of the extending direction of the first heating device 13. Furthermore, both ends of the wire-connecting portion 54 are open on one side and the other side in the height direction.

[0072] Furthermore, a positioning part 81 is formed in the wire splicing part 54 (see reference). Figure 7 as well as Figure 8 The positioning portion 81 is used to determine the position of the wire guide 70. The positioning portion 81 is formed at one end and the other end of the wire receiving portion 54 in the extending direction. More specifically, the positioning portion 81 is formed on the side of the wire receiving surface 56 closer to the extending direction than the endpoint 74 of the wire receiving surface 56 in the wire receiving portion 54, and on the other side of the extending direction than the endpoint 75 of the wire receiving surface 56 in the wire receiving portion 54.

[0073] like Figure 7 as well as Figure 8 As shown, the positioning part 81 has a set of wall portions 82 and 83, which serve as a limiting part for restricting the movement of the wire guide 70 in the extension direction. The set of wall portions 82 and 83 are formed at intervals in the extension direction. The interval between the set of wall portions 82 and 83 in the extension direction is greater than the maximum dimension of the wire guide 70 in the extension direction.

[0074] In addition, such as Figure 7 as well as Figure 8As shown, the positioning part 81 has an abutment portion 84. The abutment portion 84 is a portion that abuts against one side of the wire guide 70 in the height direction. The abutment portion 84 extends flatly in a manner parallel to the extension direction. The abutment portion 84 faces the other side in the height direction. In this embodiment, both ends of the abutment portion 84 in the extension direction are connected to a set of wall portions 82, 83.

[0075] The wire guide 70 is used to guide the wire Y traveling in the wire travel space 61. The wire guide 70 is directly mounted to the wire receiving part 54. Specifically, the wire guide 70 is installed in contact with the wire receiving part 54. The wire guide 70 is configured to be detachable from the wire receiving part 54. The wire guide 70 is, for example, a ceramic component. The wire guide 70 is, for example, a cylindrical shape with its axis along the length of the machine body (see reference). Figure 7 The diameter of the guide wire 70 is, for example, 2 mm. Figure 7 as well as Figure 8 As shown, the wire guide 70 is disposed between a set of wall portions 82 and 83. One side of the wire guide 70 in the height direction abuts against the abutment portion 84.

[0076] In addition, such as Figure 6 As shown, the wire guide 70 includes a first wire guide 70a and a second wire guide 70b. One first wire guide 70a is provided for each wire splice 54. One second wire guide 70b is provided for each wire splice 54. The first wire guide 70a is positioned outward from the end point 74 on one side of the wire splice surface 56's extension direction. The second wire guide 70b is positioned outward from the end point 75 on the other side of the wire splice surface 56's extension direction.

[0077] like Figure 7 as well as Figure 8 As shown, the first wire guide 70a is disposed between a set of wall portions 82 and 83 of the positioning portion 81 formed on one side of the wire receiving portion 54 in the extending direction, and abuts against the abutting portion 84 on one side in the height direction. Furthermore, as... Figure 8 As shown, the contact point X between the first guide wire 70a and the wire Y, when viewed from the length direction of the machine body, is located on the side of the tangent T at the end point 74 of the wire contact surface 56 that is closer to the height direction. Furthermore, this side in the height direction corresponds to the side where the wire travel space of the present invention is located.

[0078] Although not shown, the second wire guide 70b is disposed between a set of wall portions 82 and 83 of the positioning portion 81 formed on the other side of the extension direction of the wire receiving portion 54, and abuts against the abutting portion 84 on one side in the height direction. Furthermore, although not shown, the contact point between the second wire guide 70b and the wire Y, when viewed from the length direction of the machine body, is located on the side closer to the height direction than the tangent at the end point 75 of the wire receiving surface 56.

[0079] The guide wire retainer 90 is used to secure the guide wire 70. The guide wire retainer 90 is, for example, a component made of SUS steel. Figure 7 as well as Figure 8 As shown, the wire guide fixing component 90 includes two sidewalls 90a and 90b extending along the extension direction and height direction, and a top plate 90c extending along the extension direction and the length direction of the machine body. The top plate 90c is connected to the end of the two sidewalls 90a and 90b on the other side in the height direction. The wire guide fixing component 90 is mounted at both ends of the wire receiving portion 54 in the extension direction. Figure 5 As shown, the wire guide fixing member 90 installed on the wire connector 54 has an inverted U-shape in a cross section orthogonal to the extension direction.

[0080] like Figure 7 As shown, the wire guide retaining member 90 has a pressing portion 91 on one side facing the height direction, which presses the wire guide 70 against the abutment portion 84. Furthermore, the direction of the side facing the height direction corresponds to the opposite direction of the present invention. The pressing portion 91 is a leaf spring. Figure 8 As shown, the pressing part 91 is integrally formed with the top plate 90c and has a curved shape when viewed from the length direction of the machine body. For example, when the first wire guide 70a is pressed against the pressing part 91 of the abutment portion 84, the side that is curved in the extension direction opens when viewed from the length direction of the machine body. Character (reference) Figure 8 Furthermore, although not shown in the figure, when the second wire guide 70b is pressed against the pressing part 91 of the abutment portion 84, it bends and opens to the other side in the extension direction when viewed from the length direction of the machine body. Character.

[0081] In addition, such as Figure 7 As shown, through holes 92 extending along the length of the machine body are formed on the sidewalls 90a and 90b of the wire guide fixing member 90. The through holes 92 allow the wire guide 70, which abuts against the abutment portion 84, to pass through along the length of the machine body. The diameter of the through holes 92 is larger than the diameter of the wire guide 70, for example, 2.5 mm.

[0082] (Effect)

[0083] The first heating device 13 of this embodiment includes: a wire receiving portion 54 configured to be heated by a heat source 51, and having a wire travel space 61 and a wire receiving surface 56; and a wire guide 70 for guiding the wire Y traveling in the wire travel space 61. The wire guide 70 is mounted on the wire receiving portion 54. Therefore, since the wire guide 70 is integrally disposed with the wire receiving portion 54, the components sandwiched between the wire guide 70 and the wire receiving portion 54 can be eliminated or significantly reduced. Thus, the influence of manufacturing errors and assembly errors of other components can be suppressed, and the wire guide 70 can be easily and precisely configured to make the contact length between the wire Y and the wire receiving surface 56 appropriate.

[0084] In the first heating device 13 of this embodiment, the wire guide 70 is directly mounted to the wire receiving portion 54. Therefore, the wire guide 70 is directly mounted to the wire receiving portion 54, eliminating the need for components sandwiched between the wire guide 70 and the wire receiving portion 54. This also eliminates the influence of manufacturing and assembly errors of other components, allowing for a more precise configuration of the wire guide 70 to ensure an appropriate contact length between the wire Y and the wire receiving surface 56.

[0085] In the first heating device 13 of this embodiment, a positioning part 81 for determining the position of the wire guide 70 is formed in the wire receiving part 54. Therefore, the positioning part 81 can determine the position of the wire guide 70. Thus, it is easier to position the wire guide 70 at a position where the contact length between the wire Y and the wire receiving surface 56 is appropriate.

[0086] In the first heating device 13 of this embodiment, the positioning part 81 has a set of wall portions 82 and 83, which serve as limiting portions restricting the movement of the guide wire 70 in the wire travel direction. Furthermore, the guide wire 70 is disposed between the set of wall portions 82 and 83. Thus, the guide wire 70's movement in both the wire travel direction (extension direction) and to the other side is limited by the set of wall portions 82 and 83. Therefore, it is possible to more reliably suppress large-scale deviation of the guide wire 70 mounted on the wire receiving part 54 in the wire travel direction, and to suppress the contact length between the wire Y guided by the guide wire 70 and the wire receiving surface 56 from deviating from an appropriate length.

[0087] In the first heating device 13 of this embodiment, the spacing between the wire travel direction (extension direction) of the set of wall portions 82 and 83 is greater than the maximum dimension of the wire travel direction (extension direction) of the wire guide 70. Therefore, even if the maximum dimension of the wire travel direction of the wire guide 70 deviates due to manufacturing errors, the wire guide 70 can be reliably positioned between the set of wall portions 82 and 83.

[0088] In the first heating device 13 of this embodiment, the positioning part 81 has an abutting portion 84 for the guide wire 70 to abut against. Furthermore, the first heating device 13 also has a pressing part 91 that presses the guide wire 70 against the abutting portion 84 on the side facing the height direction. The tension of the yarn Y acts on the other side in the height direction. Therefore, the guide wire 70, which is in contact with the yarn Y, is inclined to separate from the abutting portion 84 due to the tension of the yarn Y. According to this embodiment, by pressing the guide wire 70 against the abutting portion 84 on the side facing the height direction by the pressing part 91, separation of the guide wire 70 from the abutting portion 84 can be suppressed. Thus, the yarn Y can be reliably guided by the guide wire 70.

[0089] Furthermore, in the first heating device 13 of this embodiment, the abutting portion 84 extends flatly in a manner parallel to the extending direction. If the abutting portion 84 is not flat, and the diameter of the wire guide 70 deviates due to manufacturing errors, the position where the wire guide 70 abuts the abutting portion 84 in the height direction will also deviate. Therefore, the position of the wire guide 70 may be offset from a position where the contact length between the wire Y and the wire receiving surface 56 is appropriate. According to this embodiment, even if the diameter of the wire guide 70 deviates due to manufacturing errors, the position where the wire guide 70 abuts the abutting portion 84 in the height direction remains constant. Therefore, regardless of manufacturing errors, the wire guide 70 can be configured with high precision to ensure that the contact length between the wire Y and the wire receiving surface 56 is appropriate.

[0090] In the first heating device 13 of this embodiment, the pressing part 91 is a leaf spring. Since the wire-connecting part 54 becomes hot, it is difficult to bond the wire guide 70 to the wire-connecting part 54. Furthermore, because the wire guide 70 is small in size, even if bolts or the like are used to install the wire guide 70 to the wire-connecting part 54, the wire guide 70 may break due to the bolts. According to this embodiment, with such a simple configuration as a leaf spring, it is possible to prevent the wire guide 70 from separating from the abutting part 84.

[0091] In the first heating device 13 of this embodiment, the wire guide 70 includes: a first wire guide 70a, disposed on the outer side of the endpoint 74 on one side of the wire-carrying direction (extension direction) of the wire-connecting surface 56; and a second wire guide 70b, disposed on the outer side of the endpoint 75 on the other side of the wire-carrying direction (extension direction) of the wire-connecting surface 56. Thus, the wire Y is guided by the first wire guide 70a disposed on the outer side of the endpoint 74 of the wire-connecting surface 56 and the second wire guide 70b disposed on the outer side of the endpoint 75 of the wire-connecting surface 56, thereby ensuring a longer contact length between the wire Y and the wire-connecting surface 56. This prevents insufficient heating of the wire Y from occurring.

[0092] In the first heating device 13 of this embodiment, the wire receiving surface 56 has a curved shape that protrudes to one side in the height direction, and the contact point X between the wire guide 70 and the wire Y is located on the side of the tangent T in the height direction that is closer to the end point 74 (or end point 75) of the wire receiving surface 56. The wire Y is prone to wear due to friction caused by contact with the end point 74 (or end point 75) of the wire receiving surface 56. According to this embodiment, the wire Y guided by the wire guide 70 floats from the end point 74 (or end point 75). Therefore, the wire Y can be made to contact the wire receiving surface 56 from the middle of its path. This prevents the wire Y, guided by the contact point X of the wire guide 70, from contacting the end point 74 (or end point 75) of the wire receiving surface 56, thus suppressing wear on the wire Y.

[0093] In the first heating device 13 of this embodiment, the wire guide 70 can be detached from the wire receiving part 54. As a result, the wire guide 70, which deteriorates due to continuous contact with the wire Y, can be easily replaced.

[0097] In the above embodiment, the first wire guide 70a is positioned outward from the end point 74 on one side of the wire-connecting surface 56 in the extending direction, and the second wire guide 70b is positioned outward from the end point 75 on the other side of the extending direction of the wire-connecting surface 56. However, the positions of the first wire guide 70a and the second wire guide 70b are not limited to those described above. For example, the first wire guide 70a may be positioned inward from the end point 74 of the wire-connecting surface 56 in the extending direction, and the second wire guide 70b may be positioned inward from the end point 75 of the wire-connecting surface 56 in the extending direction. Alternatively, the first wire guide 70a may be positioned inward from the end point 74 of the wire-connecting surface 56 in the extending direction, and the second wire guide 70b may be positioned outward from the end point 75 of the wire-connecting surface 56 in the extending direction. Alternatively, the first wire guide 70a can be positioned outward in the extending direction from the end point 74 of the wire-connecting surface 56, and the second wire guide 70b can be positioned inward in the extending direction from the end point 75 of the wire-connecting surface 56.

Furthermore, the positioning part 81 may also not have a limiting part.

[0100] In the above embodiment, the pressing part 91 is a leaf spring. However, the pressing part 91 may also be a spring other than a leaf spring, such as a compression spring, a ball spring, or a torsion spring. Alternatively, the pressing part 91 may also be an actuator that presses the wire guide 70 toward the abutment part 84 in the height direction.

[0101] In the above embodiment, the abutting portion 84 extends flatly in a manner parallel to the extending direction. However, the abutting portion 84 may also be V-shaped or U-shaped.

[0102] In the above embodiment, the wire guide 70 is cylindrical with the length direction of the machine body as its axis. However, the wire guide 70 can also be elliptical cylindrical or semi-cylindrical.

[0103] In the above embodiment, the wire guide fixing member 90 with the pressing part 91 is a different member from the wire receiving part 54. However, the pressing part 91 may also be integrally formed with the wire receiving part 54.

[0104] In the above embodiment, the first heating device 13 is an armored heater. However, the heating device of the present invention can also be applied to a Dow heat transfer fluid heater (registered trademark). Furthermore, the heating device of the present invention can also be applied to a second heating device 19.
