Description

[Technical field]

[0001] The present invention relates to a textile machine equipped with an oiling device that applies an oil to a yarn. [Background technology]

[0002] Conventionally, oiling devices that apply oil to yarns have been known. For example, Patent Document 1 discloses a spinning take-off device equipped with an oiling section (oiling device) that applies oil to a traveling yarn spun from a spinning device. The oiling section includes an oiling guide having a discharge port that discharges oil and a pair of yarn guiding members that are arranged on both sides of the discharge port in a direction perpendicular to the yarn traveling direction and guide the yarn. The pair of yarn guiding members can prevent the yarn from coming off the oiling guide if the yarn jumps. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-135335 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the oil supply device as described above, it is necessary to change the oil supply guide depending on the thickness of the yarn, the type of oil, etc. Therefore, it is desirable that the oil supply guide can be easily fixed so that the oil supply guide replacement work can be performed smoothly.

[0005] In a textile machine in which a yarn travels along a predetermined yarn path, it is important to ensure the repeatability of the position of the oil supply guide relative to the yarn path when fixing the oil supply guide. As described above, the oil supply guide is provided with a pair of yarn guiding members arranged on both sides of the discharge port in a direction perpendicular to the yarn running direction. Therefore, if the oil supply guide is fixed at an angle to the yarn running direction, it may not be possible to pass the yarn between the pair of guiding members. Therefore, it is also important to ensure the repeatability of the attitude of the oil supply guide when fixing the oil supply guide.

[0006] An object of the present invention is to provide a textile machine capable of ensuring repeatability of the position and posture of an oil supply guide relative to a yarn path and easily fixing the oil supply guide. [Means for solving the problem]

[0007] A textile machine according to a first aspect of the present invention is a textile machine equipped with an oiling device that applies an oil to a yarn traveling along a predetermined yarn path, the oiling device having a holder attached to a machine base, a discharge outlet from which an oil is discharged, and a pair of yarn guiding members that are arranged on both sides of the discharge outlet in a direction perpendicular to a yarn traveling direction in which the yarn travels and guide the yarn, and the oiling device also has an oiling guide that is detachable from the holder, a fixing member that fixes the oiling guide to the holder, and a gasket that is arranged between the holder and the oiling guide, wherein either the oiling guide or the holder is provided with a cylindrical flow path portion in which an oiling flow path through which the oil flows toward the discharge outlet is formed, and the other of the oiling guide and the holder other than the one provided with the flow path portion is provided with a cylindrical covering portion that is coaxial with the flow path portion and is capable of covering an outer circumferential surface of the flow path portion, the holder is provided with a first contact surface that can come into contact with the fixing member, and the oiling guide is provided with a second contact surface that can come into contact with the fixing member. The first contact surface is a surface that fixes the position of the fixed member in the circumferential direction of the flow path portion by contacting the fixed member, and the second contact surface is a surface that fixes the position of the oil supply guide in the circumferential direction by contacting the fixed member whose position in the circumferential direction is fixed by the first contact surface.

[0008] According to the above configuration, the position of the oil supply guide can be fixed in a plane perpendicular to the extension direction of the flow path section by inserting the flow path section into the covering section and covering the outer peripheral surface of the flow path section with the covering section. Therefore, by covering the outer peripheral surface of the flow path section with the covering section, the reproducibility of the position of the oil supply guide with respect to the yarn path can be ensured. Furthermore, by bringing the fixing member into contact with the first contact surface of the holder and the second contact surface space of the oil supply guide, the circumferential position of the oil supply guide can be fixed and the reproducibility of the attitude of the oil supply guide can be ensured. In addition, by covering the outer peripheral surface of the flow path section with the covering section and bringing the fixing member into contact with each of the contact surfaces of the holder and the oil supply guide, the oil supply guide can be easily fixed.

[0009] In the textile machine of the second invention, either the oil supply guide or the holder is provided with a recess that is recessed in the extension direction of the flow path section, and the other of the oil supply guide and the holder other than the one on which the recess is provided is provided with a protrusion that can be fitted into the recess.

[0010] According to the above configuration, by fitting the projection into the recess, it is possible to assist in circumferential alignment of the oil supply guide and the holder.

[0011] In the textile machine of the third invention, of the first contact surface and the second contact surface, the flow path portion side contact surfaces provided on the side of the oil supply guide and the holder on which the flow path portion is provided are arranged on both sides of the oil agent flow path, sandwiching the oil agent flow path, in an orthogonal direction perpendicular to the extension direction of the flow path portion.

[0012] According to the above-mentioned configuration, a large contact surface on the flow passage portion side can be ensured by simple processing, and the accuracy of reproducibility of the attitude of the oil supply guide can be improved.

[0013] In the textile machine according to a fourth aspect of the present invention, at least two of the first contact surfaces are provided, and the at least two first contact surfaces sandwich the fixed member from both sides in the circumferential direction.

[0014] According to the above configuration, the fixing member is fitted into the space between the two first contact surfaces, and thus the position of the fixing member in the circumferential direction is fixed.

[0015] In the textile machine according to a fifth aspect of the present invention, at least two of the second contact surfaces are provided, and the at least two second contact surfaces sandwich the fixed member from both sides in the circumferential direction.

[0016] According to the above configuration, the fixing member can be fitted into the space between the two second contact surfaces, thereby fixing the position of the oil feed guide in the circumferential direction.

[0017] In the textile machine of the sixth invention, the first contact surface is formed on either the flow path section or the covering section, the second contact surface is formed on a side of the flow path section or the covering section other than the side on which the first contact surface is formed, the first contact surface and the second contact surface can be arranged on the same plane, and the fixing member has a plane that contacts the first contact surface and the second contact surface arranged on the same plane.

[0018] According to the above configuration, the shape of the fixing member can be simplified.

[0019] In the textile machine according to a seventh aspect of the invention, the oil supply guide and the holder on the side on which the covering portion is provided are provided with a connection portion in which a connection flow path connected to one end of the oil agent flow path is formed, the covering portion is provided with a first orthogonal surface which is a surface perpendicular to the extension direction and faces the connection portion, the flow path portion is provided with a second orthogonal surface which is a surface perpendicular to the extension direction of the flow path portion and faces the opposite side to the connection portion, the gasket is arranged between an end face of the flow path portion on which the one end of the oil agent flow path opens and a connection face of the connection portion on which the connection flow path opens, the gasket is capable of biasing the oil supply guide in a direction in which the first orthogonal surface and the second orthogonal surface approach each other, and when the flat surface of the fixing member contacts the first contact surface and the second contact surface, the fixing member is sandwiched between the first orthogonal surface and the second orthogonal surface in the extension direction.

[0020] According to the above configuration, the oil supply guide is biased by the packing in a direction in which the first orthogonal surface and the second orthogonal surface approach each other. Therefore, by sandwiching the fixing member between the first orthogonal surface of the covering portion and the second orthogonal surface of the flow path portion in the extension direction, it is possible to accurately position the oil supply guide and the holder in the extension direction of the flow path portion without requiring precision machining or the like.

[0021] In the textile machine of the eighth invention, the holder has two third orthogonal surfaces that are surfaces perpendicular to the extension direction and are provided at both ends of the flow path section in the extension direction of the first contact surface, and the oil supply guide has two fourth orthogonal surfaces that are surfaces perpendicular to the extension direction and are provided at both ends of the flow path section in the extension direction of the second contact surface, and are opposed to the extension direction, and the distance between the two third orthogonal surfaces, the distance between the two fourth orthogonal surfaces, and the length of the fixed member in the extension direction are all the same.

[0022] According to the above configuration, when the flat surface of the fixing member contacts the first contact surface and the second contact surface, the fixing member is sandwiched from both sides in the extension direction by the third orthogonal surface and is sandwiched from both sides in the extension direction by the fourth orthogonal surface, thereby determining the positions of the oil supply guide and the holder in the extension direction.

[0023] In the textile machine according to a ninth aspect of the present invention, a groove is formed on the inner surface of the covering portion, and the packing is disposed in the groove.

[0024] According to the above configuration, the packing is less likely to move when the flow path portion and the covering portion are moved relative to each other.

[0025] In the textile machine of the 10th invention, it is possible to arrange at least one of the first contact surface and the second contact surface on one side of the central axis of the covering portion in an orthogonal direction perpendicular to the extension direction of the flow path portion, and to arrange at least one of the first contact surface and the second contact surface on the other side of the central axis in the orthogonal direction, and the fixing member is formed of a material having elastic force, and by coming into contact with at least one of the first contact surface and the second contact surface arranged on both sides of the central axis in the orthogonal direction, the fixing member clamps the flow path portion from both sides in the orthogonal direction by elastic force.

[0026] According to the above-mentioned configuration, the fixing member is unlikely to move, so that the positions of the oil supply guide and the holder can be stably fixed.

[0027] In the textile machine of the eleventh invention, the fixing member comprises a first portion having a portion in contact with the first contact surface and the second contact surface and a second portion adjacent to the first portion, an opening is formed spanning the first portion and the second portion, and the portion of the opening formed in the second portion is larger than the outer shape of the covering portion, and the fixing member can take a first position where the covering portion is inserted into the portion of the opening formed in the first portion and comes into contact with the first contact surface and the second contact surface, and a second position where the covering portion is inserted into the portion of the opening formed in the second portion and does not come into contact with the first contact surface and the second contact surface.

[0028] According to the above configuration, the fuel filler guide and the holder can be fixed together by setting the fixing member to the first position, and the fixing between the fuel filler guide and the holder can be released by setting the fixing member to the second position. Even when the fixing between the fuel filler guide and the holder is released, the covering portion remains inserted into the opening of the fixing member, so that loss of the fixing member can be prevented.

[0029] In the textile machine according to a twelfth aspect of the present invention, the first position is lower than the second position in the vertical direction.

[0030] According to the above configuration, it is possible to prevent the fixing member from unintentionally moving from the first position to the second position.

[0031] In the textile machine according to a thirteenth aspect of the present invention, the first contact surface and the second contact surface are flat surfaces.

[0032] According to the above configuration, the holder and the oil supply guide can be machined more easily than, for example, when the fixing member is provided with a screw and the first contact surface and the second contact surface are surfaces that define a screw groove.

[0033] In the textile machine according to a fourteenth aspect of the present invention, the oil supply guide is made of ceramics.

[0034] When the oil filler guide is made of ceramics, for example, if the position of the oil filler guide is fixed by fitting a male thread on the fixing member with a female thread on the oil filler guide, the oil filler guide may crack. When the circumferential position of the oil filler guide is fixed by contacting the fixing member with the flat second contact surface, cracking of the oil filler guide can be suppressed even if the oil filler guide is made of ceramics.

[0035] In the textile machine according to a fifteenth aspect of the present invention, the packing is annular.

[0036] According to the above-mentioned configuration, a single packing can seal the gap between the holder and the oil supply guide over the entire circumference, which makes it easy to process the packing.

[0037] In the textile machine according to a sixteenth aspect of the present invention, the oiling device applies an oil to a yarn traveling in a false twisting machine.

[0038] In a false twisting machine that false-twists a yarn supplied from a yarn supply package and then winds it to form a winding package, additional oil is applied to the yarn already having oil applied thereto, so the amount of oil required to be applied to the yarn is small. The oiling guide can keep the amount of oil applied to the yarn to a relatively small amount. Therefore, it is preferable to apply an oiling device having an oiling guide to a false twisting machine. With this configuration, when an oiling device having an oiling guide is applied to a false twisting machine, it is possible to easily ensure the positional repeatability and posture repeatability of the oiling guide relative to the yarn path.

[0039] In a textile machine of the 17th invention, the oil supply device further includes two yarn regulating guides spaced apart in the yarn running direction, and the holder is positioned between the two yarn regulating guides, and the textile machine uses a fixing structure of an oil supply guide according to any of the 1st to 16th inventions.

[0040] According to the above configuration, the repeatability of the position of the oil supply guide with respect to the yarn path of the yarn guided by the two yarn regulating guides and the repeatability of the attitude of the oil supply guide are ensured, and the oil supply guide can be easily fixed.

[0042] First Embodiment A false twisting machine 1 according to a first preferred embodiment of the present invention will be described with reference to Fig. 1. The direction perpendicular to the plane of the paper in Fig. 1 is the machine base longitudinal direction, and the left-right direction of the paper is the machine base width direction. The direction perpendicular to both the machine base longitudinal direction and the machine base width direction is the up-down direction (vertical direction) in which gravity acts.

[0043] The false twisting machine 1 is configured to be capable of false twisting a yarn Y made of a synthetic fiber such as nylon (a polyamide fiber) or polyester. The false twisting machine 1 includes a yarn supplying section 2 for supplying the yarn Y, a processing section 3 for false twisting the yarn Y supplied from the yarn supplying section 2, and a winding section 4 for winding the yarn Y processed by the processing section 3 onto a winding bobbin Bw.

[0044] The yarn supplying section 2 has a creel stand 5 that holds a plurality of yarn supply packages Ps. The yarn supplying section 2 supplies a plurality of yarns Y to the processing section 3. The processing section 3 false-twists the yarn Y supplied from the yarn supply package Ps. The processing section 3 is configured to include, in order from the upstream side in the yarn running direction, a first feed roller 11a, a twist stop guide 12, a heating device 13, a cooling device 14, a false-twist device 15, a tension sensor 16, a second feed roller 11b, an intertwining device 17, a third feed roller 11c, and an oiling device 20. The winding section 4 winds the yarn Y false-twisted in the processing section 3 onto a winding bobbin Bw with a winding device 10 to form a winding package Pw.

[0045] The false twisting machine 1 also has a main machine base 18 extending in the machine base longitudinal direction, and a support frame 19. The winding device 10 is attached to the main machine base 18. The main machine base 18 is disposed opposite the creel stand 5 in the machine base width direction, with the work space A in between. The devices constituting the processing section 3 are attached to the support frame 19. The devices constituting the processing section 3 are disposed above the work space A.

[0046] In the false twisting machine 1, a plurality of processing units (also called spindles) are arranged side by side in the longitudinal direction of the machine, with the yarn paths formed so as to pass through the devices constituting the processing section 3. This enables the false twisting machine 1 to simultaneously perform false twisting on a plurality of yarns Y running side by side in the longitudinal direction of the machine.

[0047] In this embodiment, the first feed roller 11a, the second feed roller 11b, and the third feed roller 11c are provided in common to a plurality of spindles (e.g., two spindles). The heating device 13 and the cooling device 14 are provided in common to a plurality of spindles (e.g., four spindles). The twist stop guide 12, the false twist device 15, the tension sensor 16, the intertwining device 17, and the oil supply device 20 are provided for each spindle.

[0048] The yarn Y supplied from the yarn supplying section 2 to the processing section 3 is stretched between the first feed roller 11a and the second feed roller 11b, and a twist is imparted to the yarn Y by the false twist device 15. The twist formed by the false twist device 15 is propagated to the twist stop guide 12, but does not propagate upstream of the twist stop guide 12 in the yarn running direction.

[0049] The yarn Y thus drawn and twisted is heated by a heating device 13, and then cooled and heat-set by a cooling device 14. The yarn Y that passes through the false twist device 15 is untwisted before it reaches the second feed roller 11b. However, since the twist of the yarn Y has been heat-set as described above, each filament maintains a wavy false twist state. An abnormality in the yarn Y, such as abnormal tension or yarn breakage, can be detected by a tension sensor 16 disposed between the false twist device 15 and the second feed roller 11b.

[0050] Thereafter, the yarn Y is slackened between the second feed roller 11b and the third feed roller 11c, and is entangled by the entangling device 17. Furthermore, an oil is applied to the yarn Y by the oil supplying device 20. The yarn Y to which the oil has been applied is wound by the winding device 10 in the winding section 4. Note that the yarn Y in the yarn supply package Ps already has oil applied thereto. The oil supplying device 20 applies additional oil to the yarn Y to which oil has already been applied.

[0051] In the false twisting machine 1, the yarn Y runs along a predetermined yarn path from the yarn supplying section 2 to the winding section 4. For example, JP 2021-127532 A discloses a spinning take-off machine equipped with an oiling guide (corresponding to the "oil guide" of the present invention) configured to combine multiple filaments spun from a spinneret into one yarn and apply an oiling agent to the yarn. The position of the oiling guide in the spinning take-off machine in the yarn running direction changes depending on the cooling state of the yarn spun from the spinneret. In other words, the optimal position of the oiling guide in the yarn running direction changes depending on the type of yarn, etc. In the spinning take-off machine configured as described above, the yarn path also changes as the position of the oiling guide changes depending on the type of yarn, etc.

[0052] (Fueling device 20) Next, the configuration of the oil supply device 20 will be described with reference to Figures 2 and 3. As shown in Figure 2, the oil supply device 20 has a plurality of oil supply guides 6, holders 7, fixing members 8, upstream yarn guides 21, and downstream yarn guides 22. An oil supply guide 6 is provided for each spindle. A plurality of oil supply guides 6 are arranged side by side in the longitudinal direction of the machine base. Oil is supplied to each oil supply guide 6 from an oil tank 70 provided in common to the plurality of oil supply guides 6.

[0053] The upstream yarn guide 21 and the downstream yarn guide 22 are spaced apart in the yarn running direction (vertical direction). The upstream yarn guide 21 is disposed upstream of each oil supply guide 6 in the yarn running direction. The downstream yarn guide 22 is disposed downstream of each oil supply guide 6 in the yarn running direction. That is, the oil supply guide 6 is located between the upstream yarn guide 21 and the downstream yarn guide 22. Between the upstream yarn guide 21 and the downstream yarn guide 22, the yarn Y is guided by the upstream yarn guide 21 and the downstream yarn guide 22, so that the yarn path of the yarn Y is determined. In order to send the yarn Y to the oil supply guide 6 in a state where the fibers are gathered, it is preferable that the upstream yarn guide 21 and the downstream yarn guide 22 are disposed near the oil supply guide 6. The upstream yarn guide 21 is disposed between the third feed roller 11c and the oil supply guide 6. The downstream yarn guide 22 is disposed between the oil supply guide 6 and the winding section 4.

[0054] The yarn Y, which is sent to the oil supply device 20 by the third feed roller 11c and travels from above downward while being guided by the upstream yarn guide 21 and the downstream yarn guide 22, comes into contact with a contact surface 62 (see FIG. 4) of the oil supply guide 6. When the yarn Y comes into contact with the contact surface 62 of the oil supply guide 6, the oil agent discharged from the discharge port 61a (see FIG. 4) is applied to the yarn Y.

[0055] (Fixing structure of oil guide 6) Next, the fixing structure of the oil supply guide 6 will be described with further reference to Figures 4 to 9. The oil supply guide 6 is detachable from the holder 7. The oil supply guide 6 is fixed to the holder 7 by a fixing member 8. As shown in Figure 3, the holder 7 is attached to a support frame 19, and is disposed between an upstream thread guide 21 and a downstream thread guide 22.

[0056] In the present disclosure, the oil supply guide 6 is made of ceramics. In the present disclosure, the holder 7 is made of metal. The holder 7 may be made of ceramics. The fixing member 8 is a sheet metal member. In the following description, references to the directions of the oil supply guide 6, the holder 7, and the fixing member 8 will be made based on the directions in a state in which the oil supply guide 6 is fixed to the holder 7.

[0057] As shown in Fig. 4, 5(a) and 5(b), the oil supply guide 6 has a guide body 60 and a flow path portion 63. The guide body 60 and the flow path portion 63 are formed integrally. The guide body 60 is provided with a contact surface 62. The flow path portion 63 is substantially cylindrical, and has an oil agent flow path 64 formed therein through which the oil agent flows toward the discharge port 61a. The guide body 60 is provided at an end portion on one side (the left side in Fig. 4) of the flow path portion 63 in the extension direction of the flow path portion 63.

[0058] The oil supply guide 6 is fixed to the holder 7 in a position in which the extension direction of the flow path section 63 coincides with the width direction of the machine base. In the following explanation, the extension direction of the flow path section 63 will be simply referred to as the "extension direction". Furthermore, the direction perpendicular to both the extension direction and the up-down direction (i.e., the longitudinal direction of the machine base, and the arrangement direction of the multiple oil supply guides 6) will be simply referred to as the "arrangement direction". The arrangement direction corresponds to the "orthogonal direction" in this invention. Furthermore, the circumferential direction of the flow path section 63 will be simply referred to as the "circumferential direction".

[0059] An end face of the guide body 60 on one side in the extension direction (the left side in Figure 4) serves as a contact surface 62. The oil flow path 64 is formed across the guide body 60 and the flow path section 63. The oil flow path 64 extends along the extension direction. An end of the oil flow path 64 on one side in the extension direction (the left side in Figure 4) is connected to a nozzle 61. The nozzle 61 connects the end of the oil flow path 64 on one side in the extension direction to an outlet 61a formed in the contact surface 62.

[0060] The guide body 60 is provided with a pair of yarn guiding members 68 arranged on both sides of the discharge port 61a in the arrangement direction, which is a direction perpendicular to the yarn running direction (vertical direction). The yarn guiding members 68 protrude to one side (the left side in FIG. 4) beyond the contact surface 62 in the extension direction. The yarn Y sent downstream of the upstream yarn guide 21 passes between the pair of yarn guiding members 68 and is guided from above to below by the pair of yarn guiding members 68.

[0061] As shown in Figs. 4, 6(a) and 6(b), the holder 7 has a covering portion 71 and a connecting portion 78. The covering portion 71 and the connecting portion 78 are integrally formed. The covering portion 71 is generally cylindrical. The covering portion 71 is disposed coaxially with the flow path portion 63 of the oil supply guide 6 and is capable of covering the outer peripheral surface of the flow path portion 63. The connecting portion 78 is provided at the end portion of the covering portion 71 on the other side in the extension direction (the right side in Fig. 4). The connecting portion 78 is formed with a connecting flow path 79 that is connected to the end portion of the oil agent flow path 64 on the other side in the extension direction (the right side in Fig. 4). The connecting flow path 79 extends along the extension direction.

[0062] The oil agent supplied from the oil agent tank 70 is sent to the oil agent flow path 64 of the oil supply guide 6 through the connecting flow path 79 of the holder 7. The oil agent sent to the oil agent flow path 64 is discharged from the nozzle 61 connected to the end of the oil agent flow path 64.

[0063] As shown in FIG. 8, the flow passage portion 63 of the oil supply guide 6 has two second spaces 65 formed therein, which are independent of the lubricant flow passage 64. The second spaces 65 are provided in a portion of the circumferential direction. The two second spaces 65 face each other with the lubricant flow passage 64 in between in the arrangement direction. The second spaces 65 are defined by grooves 66 formed in the flow passage portion 63. One groove 66 is composed of a bottom surface 66a, which is a plane, and wall surfaces 66b, which are two planes perpendicular to the extension direction. The two wall surfaces 66b are provided at both ends of the bottom surface 66a in the extension direction. The wall surfaces 66b correspond to the "fourth orthogonal surface" of the present invention. The bottom surface 66a is parallel to the extension direction. The bottom surface 66a is a surface that intersects with the circumferential direction. The bottom surface 66a is a plane extending along the up-down direction. The bottom surfaces 66a of the two second spaces 65 are disposed on either side of the oil passage 64 in the arrangement direction perpendicular to the extension direction. The second spaces 65 are open at the outer circumferential surface of the passage portion 63.

[0064] As shown in FIG. 8, two first spaces 72 are formed in the covering portion 71 of the holder 7. The first spaces 72 are provided in a part of the circumferential direction. The two first spaces 72 are located on both sides of the central axis O of the covering portion 71 in the arrangement direction. The first spaces 72 are defined by through holes 73 that penetrate the covering portion 71 from an inner surface facing the outer circumferential surface of the flow path portion 63 to an outer surface opposite the inner surface. That is, the first spaces 72 are open on both the inner surface and the outer surface of the covering portion 71.

[0065] Each through hole 73 is composed of a wall surface 73a, which is two planes parallel to the extension direction, and a wall surface 73b, which is two planes perpendicular to the extension direction. The two wall surfaces 73b are provided at both ends of the wall surface 73a in the extension direction. The wall surface 73b corresponds to the "third orthogonal surface" of the present invention. The wall surface 73a is a surface that intersects with the circumferential direction. The wall surface 73a is a plane extending along the up-down direction. The two wall surfaces 73a constituting the through hole 73 that defines the first space 72 located on the right side in FIG. 8 are located on a single plane S0 perpendicular to the arrangement direction. The two wall surfaces 73a constituting the through hole 73 that defines the first space 72 located on the left side in FIG. 8 are located on a single plane S1 perpendicular to the arrangement direction. The planes S0 and S1 are located on both sides of the central axis O with respect to the arrangement direction.

[0066] The two first spaces 72 can be arranged at positions aligned with the two second spaces 65 in the vertical direction in a state in which the covering portion 71 covers the outer circumferential surface of the flow path portion 63. As shown in Fig. 8, when the second spaces 65 and the first spaces 72 are aligned in the vertical direction, one bottom surface 66a of one second space 65 and two wall surfaces 73a of one first space 72 are located on the same plane (planes S0 and S1) perpendicular to the arrangement direction.

[0067] As shown in FIG. 8, the fixing member 8 is provided with two fitting portions 82 that can be fitted into the second space 65 and the first space 72. Each fitting portion 82 is disposed so as to straddle the second space 65 and the first space 72 that are aligned in the vertical direction, and is fitted into the second space 65 and the first space 72. The portions of the two fitting portions 82 that are fitted into the second space 65 and the first space 72 face each other with the flow path portion 63 interposed therebetween in the arrangement direction. The fixing member 8 fixes the positions of the oil supply guide 6 and the holder 7 by fitting the fitting portions 82 into the second space 65 and the first space 72 and bringing them into contact with the bottom surface 66a and the wall surface 73a. That is, the fixing member 8 functions as a latch.

[0068] As shown in FIG. 7, the fixing member 8 is composed of a first portion 81 in which a fitting portion 82 is formed, and a second portion 83 adjacent to the first portion 81. The first portion 81 and the second portion 83 are arranged vertically. The fixing member 8 is formed with an opening 80 that spans the first portion 81 and the second portion 83. The opening 80 penetrates the fixing member 8, which is a sheet metal member, in the thickness direction. The opening 80 is an opening that is closed all around. In other words, the opening 80 is not open in a direction perpendicular to the thickness direction of the fixing member 8. The portion of the opening 80 formed in the second portion 83 is larger than the outer shape of the covering portion 71 of the holder 7.

[0069] The fixing member 8 can take a first position (see FIG. 9(a)) where the covering portion 71 of the holder 7 is inserted into a portion formed in the first portion 81 of the opening 80, and a second position (see FIG. 9(b)) where the covering portion 71 of the holder 7 is inserted into a portion formed in the second portion 83 of the opening 80. The first position is lower than the second position in the vertical direction. When the fixing member 8 is in the second position, it does not contact the wall surface 73a of the holder 7 and the bottom surface 66a of the fuel supply guide 6. When the fixing member 8 is in the second position, the fixing member 8 is movable in the extension direction. By moving the fixing member 8 located in the second position downward to the first position, the fitting portion 82 can be fitted into the second space 65 and the first space 72 to come into contact with the wall surface 73a of the holder 7 and the bottom surface 66a of the fuel supply guide 6. That is, the fitting direction of the fitting portion 82 into the second space 65 and the first space 72 is the up-down direction (linear direction).

[0070] The portion of the opening 80 that is formed in the first portion 81 extends in the vertical direction. The surface that defines the opening 80 in the first portion 81 includes a plane 81a that extends in the vertical direction. As shown in Fig. 8, when the two fitting portions 82 are fitted into the second space 65 and the first space 72, this plane 81a comes into contact with the entire surfaces of the bottom surfaces 66a of the recessed grooves 66 and the two wall surfaces 73a of the through holes 73 that are arranged on the same plane.

[0071] When the two fitting portions 82 are not fitted into the second space 65 and the first space 72, the width of the portion extending in the vertical direction formed in the first portion 81 of the opening 80 is slightly narrower at the lower end than at the upper end. By fitting the two fitting portions 82 into the second space 65 and the first space 72, the portion formed in the first portion 81 of the opening 80 is pushed and spread out on both sides in the arrangement direction. Thus, by fitting the two fitting portions 82 into the second space 65 and the first space 72, the fixing member 8 can sandwich the covering portion 71 from both sides in the arrangement direction by elastic force.

[0072] When the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 is fixed in its circumferential position by a wall surface 73a of the first space 72 formed in the holder 7. In other words, the wall surface 73a corresponds to the "first contact surface" of the present invention.

[0073] 8, movement of the fixing member 8 to one side in the circumferential direction (clockwise side) is regulated by the lower wall surface 73a of the two wall surfaces 73a of the right-side first space 72 and the upper wall surface 73a of the two wall surfaces 73a of the left-side first space 72. Movement of the fixing member 8 to the other side in the circumferential direction (counterclockwise side) is regulated by the upper wall surface 73a of the two wall surfaces 73a of the right-side first space 72 and the lower wall surface 73a of the two wall surfaces 73a of the left-side first space 72. This fixes the position of the fixing member 8 in the circumferential direction.

[0074] Bottom surface 66a of second space 65 formed in oil filler guide 6 comes into contact with two fitting portions 82 of fixing member 8 in a state in which the circumferential position is fixed, thereby fixing the circumferential position of oil filler guide 6. In other words, bottom surface 66a corresponds to the "second contact surface" of the present invention. Also, bottom surface 66a corresponds to the "flow path portion side contact surface" of the present invention.

[0075] 8, movement of the oil feed guide 6 to one side in the circumferential direction (the direction of the arrow indicated by D1 in the figure: clockwise side) is regulated by the flat surface 81a of the right fitting portion 82 coming into contact with an upper portion of the bottom surface 66a of the right second space 65 and the flat surface 81a of the left fitting portion 82 coming into contact with a lower portion of the bottom surface 66a of the left second space 65. Both the upper portion of the bottom surface 66a of the right second space 65 and the lower portion of the bottom surface 66a of the left second space 65 face one side in the circumferential direction.

[0076] Furthermore, movement of the fuel filler guide 6 to the other circumferential side (the direction of the arrow indicated by D2 in the figure: counterclockwise side) is regulated by the flat surface 81a of the right fitting portion 82 coming into contact with a lower portion of the bottom surface 66a of the right second space 65 and the flat surface 81a of the left fitting portion 82 coming into contact with an upper portion of the bottom surface 66a of the left second space 65. Both the lower portion of the bottom surface 66a of the right second space 65 and the upper portion of the bottom surface 66a of the left second space 65 face toward the other circumferential side. This fixes the position of the fuel filler guide 6 in the circumferential direction.

[0077] Furthermore, when the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the movement of the fixing member 8 on both sides in the arrangement direction is restricted by the bottom surface 66a of the second space 65 and the wall surfaces 73a of the first space 72. That is, the movement of the fixing member 8 to one side in the arrangement direction (the right side in FIG. 8) is restricted by the bottom surface 66a of the second space 65 on the left in FIG. 8 and the two wall surfaces 73a of the first space 72. The movement of the fixing member 8 to the other side in the arrangement direction (the left side in FIG. 8) is restricted by the bottom surface 66a of the second space 65 on the right in FIG. 8 and the two wall surfaces 73a of the first space 72.

[0078] Here, the length (distance between two wall surfaces 66b) of the second space 65 of the oil supply guide 6 in the extension direction is L1 (see FIG. 5(b)), the length (distance between two wall surfaces 73b) of the holder 7 in the extension direction of the first space 72 is L2 (see FIG. 6(b)), and the length (thickness of the fixing member 8) of the fitting portion 82 in the extension direction is L3 (see FIG. 4). In this case, the lengths L1, L2, and L3 are substantially the same. More specifically, the length L1 of the second space 65 and the length L2 of the first space 72 are lengths such that the fitting portion 82 fits snugly into the second space 65 and the first space 72 in the extension direction. Both end faces in the extension direction of the fitting portion 82 fitted into the second space 65 and the first space 72 contact the wall surface 66b of the second space 65 and the wall surface 73b of the first space 72. That is, the fitting portion 82 is sandwiched between the two wall surfaces 66b of the second space 65 from both sides in the extension direction, and is also sandwiched between the two wall surfaces 73b of the first space 72.

[0079] 5(b), two protrusions 67 are provided at one end of flow path portion 63 of fuel filler guide 6 in the extension direction. One of the two protrusions 67 is provided at an upper part of flow path portion 63 and protrudes upward from the outer circumferential surface of flow path portion 63. The other of the two protrusions 67 is provided at a lower part of flow path portion 63 and protrudes downward from the outer circumferential surface of flow path portion 63.

[0080] As shown in Fig. 6(a), two notches 74 are provided at one end of the covering portion 71 of the holder 7 in the extension direction. The two notches 74 form a recess that is recessed in the extension direction at the edge of the covering portion 71. In other words, the notch 74 corresponds to the "recess" of the present invention. One of the two notches 74 is provided in the upper part of the covering portion 71. The other of the two notches 74 is provided in the lower part of the covering portion 71. Two protrusions 67 provided on the oil filler guide 6 are fitted into the two notches 74 provided in the holder 7, respectively.

[0081] As shown in FIG. 4, an annular packing 9 is disposed between the oil supply guide 6 and the holder 7. The packing 9 seals the gap between the oil supply guide 6 and the holder 7 over the entire circumference. The packing 9 is made of an elastic material such as rubber. The packing 9 is disposed between the first space 72 and a connection end 79a connected to the end of the oil agent passage 64 on the other side (the right side in FIG. 4) of the connection passage 79 in the extension direction. A groove 76 is provided on the inner surface of the covering portion 71 of the holder 7, the groove 76 being formed over the entire circumference of the covering portion 71. The groove 76 is provided between the first space 72 and a connection surface 78a where the connection end 79a of the connection passage 79 in the connection portion 78 opens. The packing 9 is disposed in the groove 76.

[0082] (Features of the first embodiment) As described above, in the false twisting machine 1 of this embodiment, the oil supply device 20 includes the holder 7 attached to the support frame 19, the discharge port 61a for discharging the oil agent, and a pair of yarn guide members 68 arranged on both sides of the discharge port 61a in a direction perpendicular to the yarn running direction and guiding the yarn Y, and also includes the oil supply guide 6 detachable from the holder 7, the fixing member 8 for fixing the oil supply guide 6 to the holder 7, the packing 9 arranged between the oil supply guide 6 and the holder 7, and the packing 9 arranged between the holder 7 and the oil supply guide 6. The oil supply guide 6 has a cylindrical flow path portion 63 in which an oil agent flow path 64 is formed. The holder 7 has a cylindrical covering portion 71 that is arranged coaxially with the flow path portion 63 and can cover the outer circumferential surface of the flow path portion 63. The holder 7 is provided with a wall surface 73a that can come into contact with the fixing member 8, and the oil supply guide 6 is provided with a bottom surface 66a that can come into contact with the fixing member 8. The wall surface 73a is a surface that comes into contact with the fixed member 8 to fix the position of the fixed member 8 in the circumferential direction of the flow path portion 63. The bottom surface 66a comes into contact with the fixed member 8 whose position in the circumferential direction is fixed by the wall surface 73a, to fix the position of the oil supply guide 6 in the circumferential direction.

[0083] According to the above-mentioned configuration, the flow passage portion 63 is inserted into the covering portion 71 to cover the outer peripheral surface of the flow passage portion 63 with the covering portion 71, thereby fixing the position of the oil supply guide 6 in a plane perpendicular to the extension direction of the flow passage portion 63 (i.e., a plane parallel to both the up-down direction and the arrangement direction). Therefore, by covering the outer peripheral surface of the flow passage portion 63 with the covering portion 71, it is possible to ensure the reproducibility of the position of the oil supply guide 6 with respect to the yarn path. Furthermore, by bringing the fixing member 8 into contact with the wall surface 73a of the holder 7 and the bottom surface 66a of the oil supply guide 6, it is possible to fix the position of the oil supply guide 6 in the circumferential direction and ensure the reproducibility of the attitude of the oil supply guide 6. In addition, by covering the outer peripheral surface of the flow passage portion 63 with the covering portion 71 and bringing the fixing member 8 into contact with the wall surface 73a of the holder 7 and the bottom surface 66a of the oil supply guide 6, it is possible to easily fix the oil supply guide 6.

[0084] Furthermore, in the false twisting machine 1 of this embodiment, a notch 74 recessed in the extension direction is formed in the holder 7, and a protrusion 67 that can be fitted into the notch 74 is provided in the oil supply guide 6. Therefore, by fitting the protrusion 67 of the oil supply guide 6 into the notch 74 of the holder 7, it is possible to assist in circumferential alignment of the oil supply guide 6 and the holder 7.

[0085] In addition, in the false twisting machine 1 of this embodiment, the bottom surface 66a, which is the contact surface of the oil supply guide 6 with the fixed member 8, is disposed on both sides of the oil agent passage 64 with respect to the arrangement direction perpendicular to the stretching direction. From the viewpoint of improving the accuracy of the reproducibility of the attitude of the oil supply guide 6, it is preferable to ensure a large contact surface of the oil supply guide 6 with the fixed member 8 (a surface corresponding to the "second contact surface" of the present invention). If an acute angle portion or a thin portion is formed in the oil supply guide 6 by processing the oil supply guide 6 to form a contact surface with the fixed member 8, the oil supply guide 6 may be damaged or the oil agent may leak due to processing errors. In particular, since the oil supply guide 6 of this embodiment is made of ceramics, there is a high possibility of damage. Therefore, high-precision processing is required. In the fixing structure of this embodiment, the bottom surface 66a, which is the contact surface with the fixed member 8, can be easily processed to ensure a large bottom surface, and the accuracy of the reproducibility of the attitude of the oil supply guide 6 can be improved.

[0086] Furthermore, in the false twisting machine 1 of this embodiment, the bottom surface 66a of the oil supply guide 6 and the wall surface 73a of the holder 7 can be arranged on the same plane, and the fixing member 8 has a flat surface 81a that contacts the bottom surface 66a of the oil supply guide 6 and the wall surface 73a of the holder 7, which are arranged on the same plane. Therefore, the shape of the fixing member 8 can be simplified.

[0087] In addition, in the false twisting machine 1 of this embodiment, the length L1 in the extension direction of the second space 65 (the distance between the two wall surfaces 66b) and the length L2 in the extension direction of the first space 72 (the distance between the two wall surfaces 73b) are substantially the same as the length L3 in the extension direction of the fitting portion 82. Therefore, the fitting portion 82 fitted into the second space 65 and the first space 72 is sandwiched between the wall surfaces 66b of the oil supply guide 6 from both sides in the extension direction, and is also sandwiched between the wall surfaces 73b of the holder 7 from both sides in the extension direction. This determines the positions of the oil supply guide 6 and the holder 7 in the extension direction.

[0088] Furthermore, in the false twisting machine 1 of the present embodiment, a groove 76 in which the packing 9 is disposed is formed on the inner surface of the covering portion 71 of the holder 7. Therefore, the packing 9 is less likely to move when the oil supply guide 6 is moved relative to the holder 7.

[0089] Furthermore, in the false twisting machine 1 of this embodiment, the wall surface 73a formed on the holder 7 and the bottom surface 66a formed on the oil supply guide 6 are disposed on both sides of the central axis O of the covering portion 71 in the arrangement direction perpendicular to the extension direction. The fixing member 8 is formed of a material having elasticity, and by contacting the wall surface 73a and the bottom surface 66a disposed on both sides of the central axis O in the arrangement direction, the fixing member 8 sandwiches the flow path portion 63 from both sides in the arrangement direction by elastic force. Therefore, the fixing member 8 is less likely to move, and the positions of the oil supply guide 6 and the holder 7 can be stably fixed.

[0090] In the false twisting machine 1 of this embodiment, the fixing member 8 is composed of a first portion 81 in which an inlay portion 82 is formed, which contacts the wall surface 73a of the holder 7 and the bottom surface 66a of the oil supply guide 6, and a second portion 83 adjacent to the first portion 81, and an opening 80 is formed across the first portion 81 and the second portion 83. The portion of the opening 80 formed in the second portion 83 is larger than the outer shape of the covering portion 71 of the holder 7. The fixing member 8 can take a first position where the covering portion 71 of the holder 7 is inserted into the portion of the opening 80 formed in the first portion 81 so that the inlay portion 82 contacts the wall surface 73a and the bottom surface 66a, and a second position where the covering portion 71 of the holder 7 is inserted into the portion of the opening 80 formed in the second portion 83 so that the inlay portion 82 does not contact the wall surface 73a and the bottom surface 66a. Therefore, the fuel filler guide 6 and the holder 7 can be fixed together by setting the fixing member 8 to the first position, and the fixation between the fuel filler guide 6 and the holder 7 can be released by setting the fixing member 8 to the second position. Even when the fixation between the fuel filler guide 6 and the holder 7 is released, the covering portion 71 of the holder 7 remains inserted into the opening 80 of the fixing member 8, so that the fixing member 8 can be prevented from being lost.

[0091] Furthermore, in the false twisting machine 1 of this embodiment, the first position of the fixing member 8 is lower than the second position in the up-down direction. Therefore, unless an external force is applied to lift the fixing member 8, it remains in the first position where it fixes the oil supply guide 6 and the holder 7 by gravity. This prevents the fixing member 8 from unintentionally moving from the first position to the second position, which would cause the fixation between the oil supply guide 6 and the holder 7 to be released.

[0092] In addition, in the false twisting machine 1 of this embodiment, the wall surface 73a corresponding to the first contact surface and the bottom surface 66a corresponding to the second contact surface are flat surfaces. Therefore, the holder 7 and the oil supply guide 6 can be machined more easily than in a case where, for example, the fitting portion 82 is a screw and the first and second contact surfaces are surfaces that define a screw groove.

[0093] Furthermore, in the false twisting machine 1 of this embodiment, the oil supply guide 6 is made of ceramics. For example, if the fitting portion 82 is a screw and the oil supply guide 6 is made of ceramics, there is a risk that the oil supply guide 6 will crack when the fitting portion 82 of the fixing member 8 is fitted into the second space 65 of the oil supply guide 6 to fix the position of the oil supply guide 6. In this embodiment, even if the oil supply guide 6 is made of ceramics, it is possible to prevent the oil supply guide 6 from cracking.

[0094] Furthermore, in the false twisting machine 1 of this embodiment, an annular packing 9 is disposed between the oil supply guide 6 and the holder 7. Therefore, the single packing 9 can seal the entire periphery between the oil supply guide 6 and the holder 7. This makes it easy to process the packing 9.

[0095] Furthermore, in the false twisting machine 1, additional oil is applied to the yarn Y that already has oil applied thereto, so the required amount of oil to be applied to the yarn Y is small. The oil supply guide 6 can keep the amount of oil applied to the yarn Y to a relatively small amount. Therefore, it is preferable to apply an oil supply device 20 having an oil supply guide 6 to the false twisting machine 1. According to this embodiment, when the oil supply device 20 having the oil supply guide 6 is applied to the false twisting machine 1, it is possible to easily ensure the repeatability of the position and posture of the oil supply guide 6 relative to the yarn path.

[0096] In addition, the false twisting machine 1 of this embodiment is equipped with an upstream yarn guide 21 and a downstream yarn guide 22 that are spaced apart in the yarn running direction in which the yarn Y runs. The holder 7 is located between the upstream yarn guide 21 and the downstream yarn guide 22. This ensures repeatability of the position of the oil supply guide 6 with respect to the yarn path of the yarn Y guided by the two yarn regulating guides, and repeatability of the attitude of the oil supply guide 6, and allows the oil supply guide 6 to be easily fixed.

[0097] <Second embodiment> Next, a fixing structure of an oil filler guide 6 according to a second embodiment of the present invention will be described with reference to Fig. 10. In this embodiment, the main difference from the first embodiment is the configuration of a first space 72 and a fixing member 8 provided in a holder 7. Hereinafter, configurations common to the first embodiment will be denoted by the same reference numerals and descriptions thereof will be omitted as appropriate.

[0098] In the first embodiment, two first spaces 72 are formed in the holder 7. Two wall surfaces 73a constituting the through hole 73 defining one first space 72 are located on one plane (planes S0 and S1) perpendicular to the arrangement direction. On the other hand, in the present embodiment, four first spaces 72 are formed in the holder 7. Two wall surfaces 73a (planes intersecting with the circumferential direction) constituting the through hole 73 defining one first space 72 face each other in the arrangement direction.

[0099] In a state where the covering portion 71 covers the outer peripheral surface of the flow path portion 63, two of the four first spaces 72 can be disposed above and below one of the two second spaces 65. At the same time, the remaining two of the four first spaces 72 can be disposed above and below the other of the two second spaces 65. At this time, one bottom surface 66a of one second space 65, one wall surface 73a of the first space 72 located above the second space 65, and one wall surface 73a of the first space 72 located below the second space 65 are located on one plane S2 perpendicular to the arrangement direction. In addition, among the wall surfaces 73a of the two first spaces 72 located above and below the second space 65, the wall surfaces 73a that are not located on the plane S2 are located on one plane S3 perpendicular to the arrangement direction.

[0100] The fixing member 8 of this embodiment has two fitting portions 82 and a connecting portion 183 that connects the two fitting portions 82. The fitting portions 82 are rod-shaped. The longitudinal directions of the two fitting portions 82 are parallel to each other. The connecting portion 183 connects one end of the two fitting portions 82 in the longitudinal direction.

[0101] The two fitting portions 82 are fitted into the second space 65 and the first space 72 with the side connected by the connection portion 183 facing upward. Each fitting portion 82 is fitted across the second space 65 and the two first spaces 72 located above and below the second space 65, respectively. Two wall surfaces 73a facing each other in the arrangement direction in one first space 72 come into contact with both end surfaces in the arrangement direction of the fitting portion 82 fitted into the first space 72.

[0102] When the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 has its circumferential position fixed by the wall surfaces 73a of the first spaces 72 formed in the holder 7. At this time, the portions of the fitting portions 82 fitted into the first spaces 72 are sandwiched from both sides in the circumferential direction by the two wall surfaces 73a of the first spaces 72. That is, the wall surfaces 73a correspond to the "first contact surface" of the present invention. The bottom surface 66a of the second space 65 formed in the fuel filler guide 6 comes into contact with the two fitting portions 82 of the fixing member 8 whose circumferential position is fixed, thereby fixing the circumferential position of the fuel filler guide 6. That is, the bottom surface 66a corresponds to the "second contact surface" of the present invention.

[0103] Furthermore, when the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, each fitting portion 82 is sandwiched in the arrangement direction by the bottom surface 66a of the second space 65 and the two wall surfaces 73a of the two first spaces 72, both of which are located on the plane S2, and the two wall surfaces 73a of the two first spaces 72, both of which are located on the plane S3. This limits the movement of the fixing member 8 on both sides in the arrangement direction.

[0104] In this embodiment, the two fitting portions 82 provided on the fixing member 8 may be separate. That is, the fixing member 8 may be divided into two, and each fixing member 8 may be provided with a fitting portion 82. As described above, each fitting portion 82 is sandwiched in the arrangement direction by the bottom surface 66a of the second space 65 located on the plane S2 and the two wall surfaces 73a of the two first spaces 72 located on the plane S3. Therefore, even when the fixing member 8 is divided into two, the movement of each fixing member 8 on both sides in the arrangement direction is limited. In this way, the fixing member 8 may be divided into a plurality of parts, each of which is limited in movement on both sides in the arrangement direction.

[0105] (Features of the second embodiment) As described above, in this embodiment, similarly to the first embodiment, the position repeatability of the oil supply guide 6 can be easily ensured.

[0106] In this embodiment, the through hole 73 that defines one first space 72 has two wall surfaces 73a that sandwich the fitting portion 82 from both sides in the circumferential direction. As a result, the fixing member 8 has its position in the circumferential direction fixed by fitting the fitting portion 82 into one first space 72.

[0107] <Third embodiment> Next, a fixing structure of a fuel filler guide 6 according to a third embodiment of the present invention will be described with reference to Fig. 11. In this embodiment, the main differences from the first embodiment are the configurations of a second space 65 provided in the fuel filler guide 6, a first space 72 provided in the holder 7, and a fixing member 8. Hereinafter, configurations common to the first embodiment will be given the same reference numerals and descriptions thereof will be omitted as appropriate.

[0108] In the first embodiment, two second spaces 65 are formed in the oil supply guide 6. The recessed groove 66 that defines one second space 65 is composed of one bottom surface 66a and two wall surfaces 66b perpendicular to the extension direction. On the other hand, in the present embodiment, one second space 65 is formed in the oil supply guide 6. The second space 65 is defined by a hole 266. The hole 266 has two wall surfaces 266c parallel to the extension direction in addition to one bottom surface 66a and two wall surfaces 66b perpendicular to the extension direction. The two wall surfaces 266c face each other in the arrangement direction.

[0109] In the first embodiment, two first spaces 72 are formed in the holder 7. The two wall surfaces 73a of one first space 72 are located on a plane (planes S0 and S1) perpendicular to the arrangement direction. On the other hand, in the present embodiment, one first space 72 is formed in the holder 7. The two wall surfaces 73a (planes intersecting with the circumferential direction) of one first space 72 face each other in the arrangement direction.

[0110] With the covering portion 71 covering the outer circumferential surface of the flow path portion 63, the first space 72 can be disposed above the second space 65. At this time, one of the two wall surfaces 266c of the second space 65 (right side in FIG. 11) and one of the two wall surfaces 73a of the first space 72 (right side in FIG. 11) are located on a single plane S4 perpendicular to the arrangement direction. The other of the two wall surfaces 266c (left side in FIG. 11) and the other of the two wall surfaces 73a (left side in FIG. 11) are located on a single plane S5 perpendicular to the arrangement direction.

[0111] The fixing member 8 of this embodiment has one fitting portion 82. The fitting portion 82 is rod-shaped. A top portion 283 is provided at one end of the fitting portion 82 in the longitudinal direction. The fitting portion 82 is fitted into the second space 65 and the first space 72 with the top portion 283 facing upward. The fitting portion 82 is fitted across the second space 65 and the first space 72. Two wall surfaces 266c facing each other in the arrangement direction in the second space 65 and two wall surfaces 73a facing each other in the arrangement direction in the first space 72 contact both end surfaces of the fitting portion 82 in the arrangement direction. In addition, the bottom surface 66a of the second space 65 contacts the end of the fitting portion 82 opposite to the side on which the top portion 283 is provided in the longitudinal direction.

[0112] When the fitting portion 82 of the fixing member 8 is fitted into the second space 65 and the first space 72, the fixing member 8 is fixed in its circumferential position by the wall surface 73a of the first space 72 formed in the holder 7. At this time, the fitting portion 82 is sandwiched from both sides in the circumferential direction by the two wall surfaces 73a of one first space 72. That is, the wall surface 73a corresponds to the "first contact surface" of the present invention. At this time, the two wall surfaces 266c of the second space 65 sandwich the fitting portion 82 from both sides in the circumferential direction. The two wall surfaces 266c of one second space 65 formed in the fuel supply guide 6 contact the fitting portion 82 of the fixing member 8 in a state in which the position in the circumferential direction is fixed, thereby fixing the position in the circumferential direction of the fuel supply guide 6. That is, the wall surface 266c corresponds to the "second contact surface" of the present invention.

[0113] Furthermore, when the fitting portion 82 of the fixing member 8 is fitted into the second space 65 and the first space 72, the fitting portion 82 is sandwiched in the arrangement direction by the wall surface 266c of the second space 65 and the wall surface 73a of the first space 72, both of which are located on the plane S4, and the wall surface 266c of the second space 65 and the wall surface 73a of the first space 72, both of which are located on the plane S5. This restricts the movement of the fixing member 8 on both sides in the arrangement direction.

[0114] (Features of the third embodiment) As described above, in this embodiment, similarly to the first embodiment, the position repeatability of the oil supply guide 6 can be easily ensured.

[0115] In this embodiment, the through hole 73 that defines one first space 72 has two wall surfaces 73a that sandwich the fitting portion 82 from both sides in the circumferential direction. As a result, the fixing member 8 has its position in the circumferential direction fixed by fitting one fitting portion 82 into the first space 72.

[0116] Furthermore, in this embodiment, wall surface 266c defining one second space 65 fixes the circumferential position of oil filler guide 6 by contacting fitting portion 82 of fixing member 8. Therefore, by fitting fitting portion 82 into one second space 65, the circumferential position of oil filler guide 6 can be fixed.

[0117] <Fourth embodiment> Next, a fixing structure of a fuel filler guide 6 according to a fourth embodiment of the present invention will be described with reference to Fig. 12. In this embodiment, the main differences from the first embodiment are the configurations of a second space 65 provided in the fuel filler guide 6, a first space 72 provided in the holder 7, and a fixing member 8. Hereinafter, configurations common to the first embodiment will be given the same reference numerals and descriptions thereof will be omitted as appropriate.

[0118] In the first embodiment, two second spaces 65 are formed in the oil supply guide 6. The recessed groove 66 that defines one second space 65 is composed of one bottom surface 66a and two wall surfaces 66b perpendicular to the extension direction. On the other hand, in the present embodiment, one second space 65 is formed in the oil supply guide 6. The second space 65 is defined by a hole 366. The hole 366 has two wall surfaces 366c parallel to the extension direction in addition to one bottom surface 66a and two wall surfaces 66b perpendicular to the extension direction. The two wall surfaces 366c face each other in the arrangement direction.

[0119] In the first embodiment, two first spaces 72 are formed in the holder 7. The first spaces 72 are defined by through holes 73. In the present embodiment, the first spaces 72 are defined by grooves 373. Each groove 373 is composed of a bottom surface 373a and two wall surfaces 73b perpendicular to the extension direction. In addition to the grooves 373 that define the first spaces 72, a through hole 375 is formed in the covering portion 71 of the holder 7.

[0120] With the covering portion 71 covering the outer circumferential surface of the flow path portion 63, the through hole 375 can be disposed above the second space 65. At this time, the two first spaces 72 are located on both sides of the through hole 375 in the arrangement direction.

[0121] The fixing member 8 of this embodiment has three fitting portions 82 and a connection portion 383 that connects the three fitting portions 82. The fitting portions 82 are rod-shaped. The longitudinal directions of the three fitting portions 82 are parallel to each other. The three fitting portions 82 are lined up in an orthogonal direction that is perpendicular to the longitudinal direction. The connection portion 383 connects one end of the three fitting portions 82 in the longitudinal direction to each other. Of the three fitting portions 82 lined up in the orthogonal direction, the two fitting portions 82 located at both ends have the same length. Of the three fitting portions 82 lined up in the orthogonal direction, the fitting portion 82 located in the center is shorter than the other two fitting portions 82.

[0122] The three fitting portions 82 are fitted into the second space 65 and the first space 72 with the side connected by the connection portion 383 facing upward. Of the three fitting portions 82 aligned in the orthogonal direction, the two fitting portions 82 located at both ends are fitted into the two first spaces 72, respectively. The fitting portions 82 contact the entire surface of the bottom surface 373a of the first space 72. Of the three fitting portions 82 aligned in the orthogonal direction, the fitting portion 82 located in the center is fitted into the second space 65 via the through hole 375.

[0123] When the three fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 is fixed in its circumferential position by the bottom surfaces 373a of the two first spaces 72 formed in the holder 7. That is, the bottom surfaces 373a correspond to the "first contact surface" of the present invention. At this time, the two wall surfaces 366c of the second space 65 sandwich the fitting portions 82 from both sides in the circumferential direction. The two wall surfaces 366c of one second space 65 formed in the fuel supply guide 6 contact the fitting portions 82 of the fixing member 8 in a state in which the position in the circumferential direction is fixed, thereby fixing the position in the circumferential direction of the fuel supply guide 6. That is, the wall surfaces 366c correspond to the "second contact surface" of the present invention. Note that the wall surfaces of the through hole 375 do not contact the fitting portions 82.

[0124] Furthermore, when the three fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the movement of the fixing member 8 on both sides in the arrangement direction is restricted by the two wall surfaces 366c of the second space 65 and the bottom surface 373a of the first space 72. That is, the movement of the fixing member 8 to one side in the arrangement direction (the right side in FIG. 12) is restricted by the wall surface 366c located on the right side of the two wall surfaces 366c of the second space 65 and the bottom surface 373a of the first space 72 located on the left side in FIG. 12. The movement of the fixing member 8 to the other side in the arrangement direction (the left side in FIG. 12) is restricted by the wall surface 366c located on the left side of the two wall surfaces 366c of the second space 65 and the bottom surface 373a of the first space 72 located on the right side in FIG. 12.

[0125] In this embodiment, among the three fitting portions 82 provided on the fixing member 8, the fitting portion 82 fitted into the second space 65 may be separate from the two fitting portions 82 fitted into the first space 72. That is, the fixing member 8 may be divided into two, and one fixing member 8 may be provided with a fitting portion 82 fitted into the second space 65, and the other fixing member 8 may be provided with two fitting portions 82 fitted into the first space 72. The fixing member 8 provided with the fitting portion 82 fitted into the second space 65 is restricted in movement on both sides in the arrangement direction by the two wall surfaces 366c of the second space 65. The fixing member 8 provided with the two fitting portions 82 fitted into the first space 72 is restricted in movement on both sides in the arrangement direction by the bottom surfaces 373a of the two first spaces 72. In this way, the fixing member 8 may be divided into a plurality of parts each of which is restricted in movement on both sides in the arrangement direction.

[0126] (Features of the fourth embodiment) As described above, in this embodiment, similarly to the first embodiment, the position repeatability of the oil supply guide 6 can be easily ensured.

[0127] Furthermore, in this embodiment, wall surface 366c defining one second space 65 fixes the circumferential position of oil filler guide 6 by contacting fitting portion 82 of fixing member 8. Therefore, by fitting fitting portion 82 into one second space 65, the circumferential position of oil filler guide 6 can be fixed.

[0128] <Fifth embodiment> Next, a fixing structure of a fuel filler guide 6 according to a fifth embodiment of the present invention will be described with reference to Fig. 13. In this embodiment, the main difference from the first embodiment is the configuration of a second space 65 provided in the fuel filler guide 6 and a first space 72 provided in the holder 7. Hereinafter, configurations common to the first embodiment will be denoted by the same reference numerals and descriptions thereof will be omitted as appropriate.

[0129] In the first embodiment, two second spaces 65 are formed in the oil filler guide 6. Furthermore, two first spaces 72 defined by through holes 73 are formed in the holder 7. On the other hand, in the present embodiment, one second space 65 is formed in the oil filler guide 6. Furthermore, one first space 72 defined by a through hole 73 and one first space 72 defined by a recessed groove 473 are formed in the holder 7. The two first spaces 72 are located on either side of the central axis O of the covering portion 71 in the arrangement direction.

[0130] The first space 72 defined by the through hole 73 can be arranged in a position aligned with the second space 65 in the vertical direction in a state in which the covering portion 71 covers the outer circumferential surface of the flow path portion 63. One of the two fitting portions 82 of the fixing member 8 is fitted into the second space 65 and the first space 72 aligned in the vertical direction across the second space 65 and the first space 72. The other of the two fitting portions 82 of the fixing member 8 is fitted into the first space 72 defined by the groove 473. The fitting portion 82 fitted into the first space 72 comes into contact with the entire surface of the bottom surface 473a parallel to the extension direction of the groove 473 defining the first space 72.

[0131] When the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 has its circumferential position fixed by two wall surfaces 73a of the first space 72 defined by the through hole 73 formed in the holder 7 and a bottom surface 473a of the first space 72 defined by the recessed groove 473. That is, the wall surfaces 73a and the bottom surface 473a correspond to the "first contact surface" of the present invention. The bottom surface 66a of the second space 65 formed in the fuel filler guide 6 fixes the position of the fuel filler guide 6 in the circumferential direction by contacting the fitting portions 82 of the fixing member 8 whose position in the circumferential direction is fixed. That is, the bottom surface 66a corresponds to the "second contact surface" of the present invention.

[0132] In addition, when the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the movement of the fixing member 8 on both sides in the arrangement direction is restricted by one bottom surface 66a of the groove 66 that defines the second space 65, two wall surfaces 73a of the through hole 73 that defines the first space 72, and one bottom surface 473a of the groove 473 that defines the first space 72.

[0133] (Features of the fifth embodiment) As described above, in this embodiment, similarly to the first embodiment, the position repeatability of the oil supply guide 6 can be easily ensured.

[0134] Sixth embodiment Next, a fixing structure of an oil supply guide 6 according to a sixth embodiment of the present invention will be described with reference to Fig. 14. In this embodiment, the main difference from the first embodiment is the arrangement of a packing 9. Hereinafter, components common to the first embodiment will be denoted by the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0135] In the first embodiment, the packing 9 is disposed in a groove 76 formed on the inner surface of the covering portion 71 of the holder 7. On the other hand, in the present embodiment, the packing 9 is disposed between an end face 63a (the end face on the right side in FIG. 14) at which one end of the oil agent flow passage 64 in the flow passage portion 63 of the oil supply guide 6 opens, and a connection face 78a at which a connection end 79a of a connection flow passage 79 in a connection portion 78 of the holder 7 opens. An annular groove 576 recessed toward the other side in the extension direction is formed in the connection face 78a. The packing 9 is disposed in this groove 576. As a result, when the flow passage portion 63 of the oil supply guide 6 is pressed into the covering portion 71 of the holder 7, the packing 9 urges the oil supply guide 6 toward one side in the extension direction by a repulsive force.

[0136] Here, the length of the oil filler guide 6 in the extension direction of the second space 65 is L4, the length of the holder 7 in the extension direction of the first space 72 is L5, and the length of the fitting portion 82 in the extension direction (the thickness of the fixing member 8) is L6. In this case, the lengths L4 and L5 are longer than the length L6.

[0137] When the fitting portion 82 of the fixing member 8 is fitted across the second space 65 and the first space 72 and contacts the bottom surface 66a of the fuel filler guide 6 and the wall surface 73a of the holder 7, the wall surface 66b (surface perpendicular to the extension direction) of the second space 65 of the fuel filler guide 6 contacts the surface on the other side in the extension direction of the fitting portion 82. More specifically, the surface of the two wall surfaces 66b of the second space 65 facing one side in the extension direction (the surface facing the opposite side to the connection portion 78: corresponding to the "second orthogonal surface" of the present invention) contacts the fitting portion 82. Also, the wall surface 73b (surface perpendicular to the extension direction) of the first space 72 of the holder 7 contacts the surface on one side in the extension direction of the fitting portion 82. More specifically, the surface of the two wall surfaces 73b of the first space 72 facing the other side in the extension direction (the surface facing the connection portion 78: corresponding to the "first orthogonal surface" of the present invention) comes into contact with the fitting portion 82. That is, the fitting portion 82 is sandwiched from both sides in the extension direction by the surface of the two wall surfaces 66b of the second space 65 facing one side in the extension direction and the surface of the two wall surfaces 73b of the first space 72 facing the other side in the extension direction. The oil supply guide 6 is biased by the packing 9 in a direction in which the wall surface 66b facing one side in the extension direction approaches the wall surface 73b facing the other side in the extension direction.

[0138] (Features of the sixth embodiment) As described above, in this embodiment, similarly to the first embodiment, the position repeatability of the oil supply guide 6 can be easily ensured.

[0139] In this embodiment, the oil filler guide 6 is biased by the packing 9 in a direction in which one of the two wall surfaces 66b of the second space 65 facing one side in the extension direction approaches the one of the two wall surfaces 73b of the first space 72 facing the other side in the extension direction. Therefore, by sandwiching the fitting portion 82 of the fixing member 8 between the wall surface 66b facing one side in the extension direction and the wall surface 73b facing the other side in the extension direction, it is possible to accurately position the oil filler guide 6 and the holder 7 in the extension direction without requiring precision machining or the like.

[0140] Although the embodiments of the present invention have been described above based on the drawings, the specific configuration should not be considered to be limited to these embodiments. The scope of the present invention is indicated by the claims rather than the description of the above embodiments, and further includes all modifications within the meaning and scope of the claims.

[0141] That is, in the above-mentioned first embodiment, two second spaces 65 and two first spaces 72 are provided. One bottom surface 66a of one second space 65 and two wall surfaces 73a of one first space 72 are located on one plane S0. One bottom surface 66a of the other second space 65 and two wall surfaces 73a of the other first space 72 are located on one plane S1. Both planes S0 and S1 are planes perpendicular to the arrangement direction. However, this is not limited to this.

[0142] 15, the plane S6 on which one bottom surface 66a of one second space 65 (on the right in the figure) and two wall surfaces 73a of one first space 72 (on the right in the figure) are located is inclined with respect to a plane perpendicular to the arrangement direction. More specifically, the plane S6 is a plane parallel to the extension direction, and is inclined so that the upper wall surface 73a of the two wall surfaces 73a is located closer to the other side of the arrangement direction than the lower wall surface 73a.

[0143] Moreover, the plane S7 on which one bottom surface 66a of the other second space 65 (left in the drawing) and two wall surfaces 73a of the other first space 72 (left in the drawing) are located is also inclined with respect to a plane perpendicular to the arrangement direction. More specifically, the plane S7 is a plane parallel to the extension direction, and is inclined so that the upper wall surface 73a of the two wall surfaces 73a is located closer to one side in the arrangement direction than the lower wall surface 73a.

[0144] In addition, in the above-mentioned first embodiment, a case was described in which the fitting portion 82 fitted into the second space 65 and the first space 72 contacts one bottom surface 66a of the second space 65 and two wall surfaces 73a of the first space 72, but this is not limited to this.

[0145] 16, the fitting portion 82 fitted into the second space 65 and the first space 72 contacts an upper portion of one bottom surface 66a of the second space 65 and the upper one of the two wall surfaces 73a of the first space 72. In other words, the fitting portion 82 does not contact a lower portion of the bottom surface 66a and the lower one of the two wall surfaces 73a of the first space 72.

[0146] In the second modified example of the first embodiment, movement of the oil filler guide 6 to one side in the circumferential direction (clockwise side) is restricted by the fitting portion 82 fitted into the second space 65 and the first space 72 on the right in Fig. 16 coming into contact with an upper portion of the bottom surface 66a. Movement of the oil filler guide 6 to the other side in the circumferential direction (counterclockwise side) is restricted by the fitting portion 82 fitted into the second space 65 and the first space 72 on the left in Fig. 16 coming into contact with an upper portion of the bottom surface 66a.

[0147] Similarly, in the second embodiment, the case has been described in which each fitting portion 82 is fitted across the second space 65 and the two first spaces 72 located above and below the second space 65, respectively, but this is not limited thereto. That is, the fitting portion 82 may be fitted across only the second space 65 and the first space 72 located above the second space 65.

[0148] In the third embodiment, the fitting portion 82 fitted across the second space 65 and the first space 72 is in contact with the bottom surface 66a of the second space 65. However, the present invention is not limited to this. In other words, the fitting portion 82 does not have to be in contact with the bottom surface 66a.

[0149] Furthermore, in the fourth and fifth embodiments, the fitting portion 82 is in contact with the entire surface of the bottom surface 373a, 473a of the recessed groove 373, 473 that defines the first space 72. However, the present invention is not limited to this. The fitting portion 82 may be in contact with only a part of the bottom surface 373a, 473a. In the fifth embodiment, the fitting portion 82 that is fitted across the second space 65 and the first space 72 may not be in contact with the lower one of the two wall surfaces 73a of the first space 72.

[0150] In the second and third embodiments, the wall surfaces defining one first space 72 include two wall surfaces 73a that sandwich the fitting portion 82 from both sides in the arrangement direction, but the present invention is not limited to this. The two wall surfaces 73a may sandwich the fitting portion 82 in a direction intersecting with the extension direction, and may sandwich the fitting portion 82 in the up-down direction, for example.

[0151] Furthermore, in the above-mentioned fifth embodiment, the two wall surfaces 73a of the first space 72 located on the right in Fig. 13 and the bottom surface 473a of the first space 72 located on the left in Fig. 13 are the "first contact surface" of the present invention. However, in the fixing structure of the fuel filler guide 6 according to the first modified example of the fifth embodiment shown in Fig. 17, only the bottom surface 473a of the first space 72 located on the left in the figure is the "first contact surface" of the present invention. In other words, the two wall surfaces 73a of the first space 72 located on the right in Fig. 17 do not contact the fitting portion 82.

[0152] In addition, in the above embodiment, the flow path portion 63 is provided in the oil filler guide 6, and the covering portion 71 is provided in the holder 7, but this is not limited to the above. That is, the flow path portion 63 may be provided in the holder 7, and the covering portion 71 may be provided in the oil filler guide 6.

[0153] In the above embodiment, the case has been described in which the flow passage portion 63 of the fuel filler guide 6 is provided with the bottom surface 66a functioning as the second contact surface of the present invention, and the covering portion 71 of the holder 7 is provided with the wall surface 73a functioning as the first contact surface of the present invention, but the present invention is not limited to this. The surface functioning as the first contact surface and the surface functioning as the second contact surface do not necessarily have to be provided in the portion where the fuel filler guide 6 and the holder 7 overlap, such as the flow passage portion 63 and the covering portion 71. That is, for example, the wall surface 73a functioning as the first contact surface may be provided in the connection portion 78 of the holder 7. The bottom surface 66a functioning as the second contact surface may be provided in the guide body 60 of the fuel filler guide 6.

[0154] In the above embodiment, the two projections 67 provided on the oil supply guide 6 are fitted into the two notches 74 provided on the holder 7 to assist in circumferential alignment of the oil supply guide 6 and the holder 7, but the present invention is not limited to this. The notches 74 may be recesses that are recessed in the extension direction of the holder 7. That is, for example, holes may be provided instead of the notches 74. Furthermore, the number of notches 74 and projections 67 is not limited to two. There may be one set of notches 74 and projections 67, or three or more sets of notches 74 and projections 67. The notches 74 and projections 67 may not be provided.

[0155] Furthermore, in the above-described first embodiment, a case has been described in which groove 76 in which packing 9 is disposed is formed on the inner surface of covering portion 71 of holder 7. Also, in the above-described sixth embodiment, a case has been described in which groove 576 in which packing 9 is disposed is formed on connection surface 78a of connection portion 78 of holder 7. However, these grooves 76 and 576 do not necessarily have to be formed.

[0156] In the above-described first embodiment, the two wall surfaces 73a of the holder 7 and the one bottom surface 66a of the oil supply guide 6 are disposed on both sides of the central axis O in the arrangement direction. The fixing member 8 is formed of a material having elasticity, and the flow passage portion 63 is sandwiched from both sides in the arrangement direction by elastic force by contacting with the wall surface 73a and the bottom surface 66a disposed on both sides of the central axis O in the arrangement direction, but this is not limited thereto. That is, it is sufficient that at least one of the wall surface 73a and the bottom surface 66a is disposed on one side of the central axis O in the arrangement direction, and at least one of the wall surface 73a and the bottom surface 66a is disposed on the other side of the central axis O in the arrangement direction. In addition, the fixing member 8 does not have to be formed of a material having elasticity.

[0157] In addition, in the above-described embodiment, the fixing member 8 can take a first position where the fitting portion 82 is fitted into the second space 65 and the first space 72, and a second position where the fitting portion 82 is not fitted into the second space 65 and the first space 72. The first position is below the second position. However, this is not limited to this. That is, for example, the first position and the second position may be adjacent positions in the arrangement direction. Furthermore, the fixing member 8 does not have to take the first position and the second position with the opening 80 inserted into the holder 7, and may be configured to be removed from the holder 7 when releasing the fixation of the fuel filler guide 6.

[0158] In the above embodiment, the fitting direction of the fitting portion 82 into the second space 65 and the first space 72 is the vertical direction (linear direction), but this is not limited thereto. The fitting direction may be any direction that intersects with the circumferential direction.

[0159] Furthermore, in the above embodiment, the wall surface 73a functioning as the first contact surface of the present invention and the bottom surface 66a functioning as the second contact surface of the present invention are flat surfaces, but this is not limited thereto. That is, for example, the fitting portion 82 may be a screw, and the surface functioning as the first contact surface and the surface functioning as the second contact surface may be surfaces that define a screw groove.

[0160] In addition, in the above embodiment, the packing 9 is annular, but the present invention is not limited to this. For example, the packing 9 may be divided into a plurality of parts.

[0161] Furthermore, in the above embodiment, the oil filler guide 6 is made of ceramics, but the material of the oil filler guide 6 is not limited to ceramics. For example, stainless steel, a metal with a plated surface, or the like may be used as the material of the oil filler guide 6. Furthermore, the oil filler guide 6 may be partially made of ceramics, with the remaining portion being made of a material other than ceramics.

[0162] Furthermore, in the above embodiment, the holder 7 is located between the upstream thread guide 21 and the downstream thread guide 22, but this is not limited to the above. Only one of the upstream thread guide 21 and the downstream thread guide 22 may be provided, or neither of them may be provided.

[0163] In the above embodiment, a false twisting machine equipped with an oiling device has been described, but the present invention is not limited thereto. The present invention can be applied to any textile machine equipped with an oiling device that applies an oil to a yarn traveling along a predetermined yarn path. That is, for example, as disclosed in JP 2015-187324 A, in a take-up device that takes up a yarn spun from a spinning machine and is equipped with a yarn dividing guide that divides multiple yarns at predetermined intervals, the yarns travel along a predetermined yarn path. Therefore, the present invention can be applied to such a device. [Explanation of symbols]
