[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-3167 A Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, the false twisting machine of Patent Document 1 simply releases to the outside the static electricity generated by the transport of the yarn, but does not effectively utilize this static electricity.

[0005] An object of the present invention is to provide a yarn processing equipment and a yarn processing equipment system that can effectively utilize static electricity generated by the transportation of a yarn. [Means for solving the problem]

[0006] The yarn processing equipment of the first invention includes at least one contact portion that is conductive and contacts a traveling yarn, at least one electricity storage device having a first terminal and a second terminal and capable of being charged by applying a voltage between the first terminal and the second terminal, a voltage application circuit connected between the contact portion and the electricity storage device and applying a voltage between the first terminal and the second terminal so that the first terminal has a higher potential than the second terminal due to a static electricity charge generated by friction between the traveling yarn and the contact portion regardless of the polarity of the static electricity, an electric device connected to the electricity storage device, and a first switching unit connected between the electric device and either the first terminal or the second terminal of the electricity storage device, for switching between a connection between the electricity storage device and the electric device and a disconnection thereof.

[0007] In the present invention, when the connection between the storage device and the electric device is cut off by the first switching unit, the storage device can be charged by the charge of static electricity generated at the contact part due to friction between the traveling yarn and the contact part. Here, the polarity of the static electricity generated at the contact part changes depending on the type of yarn, the type of oil applied to the yarn, the degree of adhesion of the oil applied to the yarn, and the like. Therefore, in the present invention, a voltage application circuit is connected between the contact part and the storage device, and a voltage is applied between the first terminal and the second terminal of the storage device so that the first terminal of the storage device has a higher potential than the second terminal, regardless of the polarity of the static electricity generated at the contact part. This allows the storage device to be charged regardless of the polarity of the static electricity generated at the contact part, and the storage device can be charged efficiently. Then, the storage device is charged by the charge of static electricity generated at the contact part, and the static electricity generated at the contact part can be removed.

[0008] In addition, when it is necessary to drive an electric device, the electric device can be driven using the charge stored in the electric storage device by connecting the electric storage device and the electric device using the first switching unit while the electric storage device is in a charged state.

[0009] A yarn processing equipment according to a second aspect of the present invention is the yarn processing equipment according to the first aspect of the present invention, wherein the voltage application circuit is a full-wave rectifier circuit.

[0010] The full-wave rectifier circuit allows a voltage to be applied between the first terminal and the second terminal so that the first terminal has a higher potential than the second terminal, regardless of the polarity of the static electricity generated at the contact portion. This allows the power storage device to be charged regardless of the polarity of the static electricity generated at the contact portion, and allows the power storage device to be charged efficiently.

[0011] The yarn processing equipment of the third invention is the yarn processing equipment of the first or second invention, and is provided with a stationary guide as the contact part, around which the yarn is hung and which does not move in accordance with the running of the yarn.

[0012] A stationary guide that does not move in accordance with the running of the yarn has a large friction with the running yarn and generates a large amount of static electricity compared to a roller or the like that moves in accordance with the running of the yarn. In the present invention, the electricity storage device is charged by the static charge generated in the stationary guide as a contact part, so that the electricity storage device can be charged efficiently. In addition, by charging the electricity storage device, the large amount of static electricity generated in the stationary guide can be removed.

[0013] In addition, the surface of the stationary guide gradually wears due to friction with the yarn, and the amount of static charge generated on the stationary guide changes depending on the degree of wear on the surface of the stationary guide. Therefore, in the present invention, the degree of wear on the stationary guide can be detected based on the change in the amount of charge due to the change in the static charge generated on the stationary guide.

[0014] The yarn processing equipment according to a fourth aspect of the present invention is the yarn processing equipment according to any one of the first to third aspects of the present invention, further comprising a transport roller as the contact part for transporting a plurality of yarns.

[0015] A conveying roller that conveys a plurality of yarns generates static electricity due to friction with each of the plurality of yarns, and the total amount of static electricity generated is large. In the present invention, the electricity storage device is charged by the charge of static electricity generated on the conveying roller as a contact part, so that the electricity storage device can be charged efficiently. In addition, by charging the electricity storage device, the large amount of static electricity generated on the conveying roller can be removed.

[0016] The conveying rollers convey the yarn while gripping it. In the yarn processing equipment, the rotation speed of the conveying rollers is sometimes changed to adjust the tension of the traveling yarn. In the present invention, the degree of grip of the yarn by the conveying rollers, in other words, the degree of slippage between the conveying rollers and the yarn, can be detected based on the charge of the electricity storage device caused by the static electricity generated on the conveying rollers.

[0017] The yarn processing equipment of the fifth invention is a yarn processing equipment of any of the first to fourth inventions, and includes a winding unit that winds a running yarn onto a bobbin to form a package, the winding unit having a contact roller as the contact unit that contacts the yarn located on the surface of the package being wound, and a winding detection unit that detects winding of the yarn around the contact roller.

[0018] Generally, in yarn processing equipment (yarn winding equipment) that winds a traveling yarn onto a bobbin to form a package, the traveling speed of the yarn is high. Therefore, friction between the traveling yarn and the contact parts is high, and a large amount of static electricity is generated at the contact parts. In the present invention, the electricity storage device is charged by the static electricity generated at the contact parts of the yarn winding equipment, where the yarn traveling speed is high, so that the electricity storage device can be charged efficiently. In addition, by charging the electricity storage device, the large amount of static electricity generated at the contact parts of the yarn winding equipment can be removed.

[0019] In addition, since the contact roller rotates while in contact with the yarn located on the surface of the package being wound, a large amount of static electricity is generated on the contact roller. In the present invention, the static electricity generated on the contact roller as a contact part charges the storage device, so that the static electricity on the contact roller can be removed by charging the storage device.

[0020] In addition, since the winding detection unit that detects the winding of the yarn around the contact roller is disposed close to the contact roller, when static electricity is generated on the contact roller, discharge is likely to occur between the contact roller and the winding detection unit. In the present invention, the power storage device is charged by the charge of static electricity generated on the contact roller as a contact part, so that the static electricity on the contact roller is removed by charging the power storage device, and discharge between the contact roller and the winding detection unit can be suppressed.

[0021] The yarn processing equipment of the sixth invention is a yarn processing equipment of any of the first to fifth inventions, and includes a winding section that winds a running yarn onto a bobbin to form a package, the winding section having a traverse device that traverses the yarn in the axial direction of the bobbin when winding the yarn onto the bobbin, the traverse device having a moving guide that holds the yarn and moves back and forth in the axial direction of the bobbin, and a fulcrum guide that supports the yarn upstream of the moving guide in the running direction of the yarn, and the moving guide and the contact section.

[0022] The moving guide of the traverse device generates static electricity due to friction with the traveling yarn. In the present invention, the electricity storage device is charged by the static electricity generated on the moving guide as a contact part, so that the electricity storage device can be charged efficiently.

[0023] The yarn processing equipment of the seventh invention is a yarn processing equipment of any of the first to sixth inventions, and includes a winding section that winds a running yarn onto a bobbin to form a package, the winding section having a traverse device that traverses the yarn in the axial direction of the bobbin when winding the yarn onto the bobbin, the traverse device having a moving guide that holds the yarn and moves back and forth in the axial direction of the bobbin, and a fulcrum guide that supports the yarn upstream of the moving guide in the running direction of the yarn, and the fulcrum guide is the contact section.

[0024] The fulcrum guide of the traverse device is the fulcrum of the traverse, and therefore the bending angle of the yarn is larger than that of other fixed guides, and the static electricity generated is large. In the present invention, the electricity storage device is charged by the static electricity generated in the fulcrum guide as a contact part, and therefore the electricity storage device can be charged efficiently.

[0025] In addition, in a configuration in which multiple yarns are wound around multiple winding sections, the traverse device is separate for each of the multiple yarns. This makes it possible to detect yarn breakage based on whether the electricity storage device is charged by static electricity generated on the fulcrum guide (whether static electricity is generated on the fulcrum guide).

[0026] The yarn processing equipment of the eighth invention is a yarn processing equipment of any of the first to seventh inventions, and is equipped with an oil application section that is located upstream of the contact section in the running direction of the yarn and applies an oil to the yarn.

[0027] The polarity of static electricity generated at the contact portion due to friction between the oil-coated yarn and the contact portion may change depending on the brand of oil applied to the yarn, the type of oil, changes in the surrounding environment such as humidity, etc. Therefore, in the present invention, a voltage application circuit is connected between the contact portion and the electricity storage device, and a voltage is applied between the first terminal and the second terminal of the electricity storage device so that the first terminal has a higher potential than the second terminal, regardless of the polarity of the static electricity generated at the contact portion. This allows charging of the electricity storage device to continue even if the polarity of the static electricity generated at the contact portion changes due to variations in the degree of adhesion of the oil applied to the yarn.

[0028] The yarn processing equipment of a ninth invention is the yarn processing equipment of any of the first to eighth inventions, and includes a second switching unit that switches whether the contact portion is connected to the voltage application circuit or grounded, and a full charge detection unit that detects whether the power storage device is fully charged, and the second switching unit is configured to connect the contact portion to the voltage application circuit when the full charge detection unit detects that the power storage device is not fully charged, and to ground the contact portion when the full charge detection unit detects that the power storage device is fully charged.

[0029] When the power storage device is not fully charged, the contact part can be connected to a voltage application circuit to charge the power storage device using static electricity generated at the contact part.When the power storage device is fully charged, the contact part can be grounded to allow static electricity generated at the contact part to escape to the outside.

[0030] A yarn processing equipment system according to a tenth aspect of the present invention is a yarn processing equipment system comprising a yarn processing equipment and an electric device arranged outside the yarn processing equipment, wherein the yarn processing equipment comprises: at least one contact portion that is conductive and contacts a running yarn; at least one power storage device having a first terminal and a second terminal and that can be charged by applying a voltage between the first terminal and the second terminal; a voltage application circuit connected between the contact portion and the power storage device and applying a voltage between the first terminal and the second terminal so that the first terminal has a higher potential than the second terminal due to a static electricity charge generated by friction between the running yarn and the contact portion regardless of the polarity of the static electricity; and a switching unit connected between either the first terminal or the second terminal of the power storage device and the electric device and switching between connection and disconnection of the power storage device and the electric device.

[0031] In the present invention, when the connection between the storage device and the electric device is cut off by the switching unit, the storage device can be charged by the charge of static electricity generated at the contact part due to friction between the traveling yarn and the contact part. Here, the polarity of the static electricity generated at the contact part changes depending on the type of yarn, the type of oil applied to the yarn, the degree of adhesion of the oil applied to the yarn, and the like. Therefore, in the present invention, a voltage application circuit is connected between the contact part and the storage device, and a voltage is applied between the first terminal and the second terminal of the storage device so that the first terminal of the storage device has a higher potential than the second terminal, regardless of the polarity of the static electricity generated at the contact part. This allows the storage device to be charged regardless of the polarity of the static electricity generated at the contact part, and the storage device can be charged efficiently. Then, the storage device is charged by the charge of static electricity generated at the contact part, and the static electricity generated at the contact part can be removed.

[0032] Furthermore, in the present invention, when it is necessary to drive the electric device, the electric storage device can be charged and the switching unit can be used to connect the electric storage device to an electric device provided outside the yarn processing equipment, thereby enabling the electric device to be driven using the charge stored in the electric storage device.

[0033] The yarn processing equipment system of the 11th invention is the yarn processing equipment system of the 10th invention, and comprises a plurality of the yarn processing equipment and one electric device connected to the plurality of the yarn processing equipment.

[0034] According to the present invention, a single electric device can be driven using the electric charge stored in the power storage devices of multiple yarn processing equipment. Therefore, even if the amount of electric charge stored in the power storage devices of each yarn processing equipment is not particularly large, the electric device can be driven as long as the total amount of electric charge is relatively large. Effect of the Invention

[0035] According to the present invention, the static electricity generated on the contact portion can be removed by charging the storage device with the charge of the static electricity generated on the contact portion regardless of the polarity of the static electricity generated on the contact portion. Also, when it is necessary to drive an electrically-driven device, the charge stored in the storage device can be used to drive the electrically-driven device. [Brief description of the drawings]

[0037] Preferred embodiments of the present invention will now be described.

[0038] <Outline of take-up winder> As shown in Figs. 1 and 2, the take-up winder 1 according to this embodiment (the "yarn processing equipment" of the present invention) includes a drawing section 3, a take-up section 4, and a take-up section 5. The take-up section 4 and the take-up section 5 are located below the drawing section 3. In the following, the vertical direction, the front-rear direction, and the left-right direction are defined as shown in Figs. 1 and 2. The vertical direction is the direction in which gravity acts. The front-rear direction, the left-right direction, and the vertical direction are mutually orthogonal. In the following, the upper and lower sides in the vertical direction, the right and left sides in the left-right direction, and the front and rear sides in the front-rear direction are defined as shown in Figs. 1 and 2.

[0039] <Extension part> As shown in Fig. 1, the drawing section 3 draws a plurality of yarns Y produced by continuously spinning a molten fiber material such as polyester from a spinning device 2 above. The drawing section 3 includes an oil supply guide 10 ("oil agent application section" of the present invention) and five godet rollers 11a to 11e. The oil supply guide 10 applies an oil agent to each of the plurality of yarns Y spun from the spinning device 2.

[0040] The five godet rollers 11a to 11e are rollers whose axial direction is parallel to the front-rear direction, and are each rotated by a motor (not shown). Each of the five godet rollers 11a to 11e is made of a conductive material such as metal and has a heater inside. The five godet rollers 11a to 11e are housed in a rectangular parallelepiped insulation box 12. A yarn inlet 12a for introducing the multiple yarns Y into the insulation box 12 and a yarn outlet 12b for leading the multiple yarns Y from the insulation box 12 to the outside are formed on the right side wall of the insulation box 12.

[0041] The multiple yarns Y to which the oil has been applied in the oil supply guide 10 are guided through the guide roller 13 and into the heat-insulating box 12 from the yarn introduction port 12a. The guide roller 13 is a roller whose axial direction is parallel to the front-rear direction and is made of a conductive material such as metal. The multiple yarns Y introduced into the heat-insulating box 12 are wound around the five godet rollers 11a to 11e in order.

[0042] The three upstream godet rollers 11a to 11c are heating rollers for preheating the yarns Y before drawing them. The surface temperatures of the godet rollers 11a to 11c are set to a temperature equal to or higher than the glass transition temperature of the yarns Y.

[0043] The two downstream godet rollers 11d and 11e are heating rollers for thermally setting the drawn yarns Y. The surface temperatures of the godet rollers 11d and 11e are set higher than the surface temperatures of the three upstream godet rollers 11a to 11c. The surface speeds of the two downstream godet rollers 11d and 11e are faster than the surface speeds of the three upstream godet rollers 11a to 11c.

[0044] The yarns Y introduced into the thermal insulation box 12 from the yarn inlet 12a are first preheated to a temperature at which they can be stretched, i.e., a temperature equal to or higher than the glass transition temperature, while being sent by the three upstream godet rollers 11a to 11c. Next, the preheated yarns Y are stretched by the difference in surface speed between the godet roller 11c and the godet roller 11d. Furthermore, the yarns Y are heated to a higher temperature while being sent by the two downstream godet rollers 11d and 11e, and the stretched state is heat set. The yarns Y stretched as described above are led out of the thermal insulation box 12 from the yarn outlet 12b, and are further sent to the take-up section 4 by the guide roller 14. The guide roller 14 is a roller whose axial direction is parallel to the front-rear direction, and is made of a conductive material such as metal.

[0045] As shown in FIG. 2, the take-off section 4 includes a godet roller 21 and a godet roller 22.

[0046] The godet roller 21 is a roller whose axial direction is parallel to the left-right direction, and is located below the guide roller 14. The multiple yarns Y sent to the take-up section 4 by the guide roller 14 are taken up by the godet roller 21. The godet roller 21 is driven by a motor (not shown).

[0047] The godet roller 22 is a roller whose axial direction is parallel to the left-right direction, and is disposed rearward of the godet roller 21. The godet roller 22 is driven by a motor (not shown). The take-up unit 4 is provided with a guide rail 23 that extends upward in the vertical direction toward the rear in the front-rear direction. The godet roller 22 is connected to a motor (not shown) via a pulley, a belt, etc. (not shown). When the motor is driven, the godet roller 22 moves along the guide rail 23. As a result, the godet roller 22 can move between a rear position shown by a solid line in FIG. 2 when winding the yarn Y, and a front position shown by a dashed line in FIG. 2 in close proximity to the godet roller 21 when threading the yarn.

[0048] <Winding section> The winding unit 5 includes a plurality of traverse devices 30, a turret 33, two bobbin holders 34, a contact roller 35, and a winding detection unit 36. The plurality of traverse devices 30 are provided individually for the plurality of yarns Y and are arranged in the front-rear direction. Each traverse device 30 has a fulcrum guide 31 (the "stationary guide" of the present invention) and a traverse guide 32 (the "moving guide" of the present invention).

[0049] The fulcrum guide 31 is made of a conductive material such as metal. The fulcrum guides 31 of the traverse devices 30 are attached to sliders 37. The sliders 37 are supported so as to be movable in the front-rear direction along a guide rail 38 extending in the front-rear direction. The sliders 37 are also connected to a cylinder (not shown). When the cylinder is driven, the sliders 37 move in the front-rear direction along the guide rail 38. This allows the fulcrum guides 31 to move between positions spaced apart from each other in the front-rear direction when winding the yarn Y and a position moved toward the front when threading the yarn.

[0050] The traverse guide 32 is made of a conductive material such as metal, and is disposed downstream of the fulcrum guide 31 in the running direction of the yarn Y. The traverse guide 32 is driven by a motor (not shown) to reciprocate in the front-rear direction. As a result, the yarn Y hung on the traverse guide 32 is traversed around the fulcrum guide 31, which is disposed upstream of the traverse guide 32 in the running direction of the yarn Y.

[0051] The turret 33 is a disk-shaped member whose axial direction is parallel to the front-rear direction. The turret 33 is driven to rotate by a motor (not shown). The two bobbin holders 34 each have an axial direction parallel to the front-rear direction, and are rotatably supported at the upper and lower ends of the turret 33. A plurality of bobbins B, which are individually provided for a plurality of yarns Y, are attached to each of the bobbin holders 34 and aligned in the front-rear direction. The two bobbin holders 34 are each driven individually by a motor (not shown).

[0052] When the upper bobbin holder 34 is rotated, the yarn Y traversed by the traverse guide 32 is wound onto the bobbin B to form the package P. After the formation of the package P is completed, the turret 33 is rotated to switch the upper and lower positions of the two bobbin holders 34. As a result, the bobbin holder 34 that was previously located on the lower side moves to the upper side, and the yarn Y is wound onto the bobbin B attached to this bobbin holder 34 to form the package P. The bobbin holder 34 that was previously located on the upper side moves to the lower side, making it possible to collect the package P.

[0053] The contact roller 35 is a roller whose axial direction is parallel to the front-rear direction and is made of a conductive material such as metal. The contact roller 35 is disposed immediately above the upper bobbin holder 34. The contact roller 35 comes into contact with the yarn Y on the surfaces of the multiple packages P in which the yarn Y is wound around the bobbins B attached to the upper bobbin holder 34, thereby applying contact pressure to the surfaces of the packages P during winding.

[0054] The winding detection unit 36 ​​is located immediately above the contact roller 35. The winding detection unit 36 ​​detects the winding of the yarn Y around the contact roller 35.

[0055] <Charging section configuration> The take-up winder 1 of this embodiment also includes a charging section 6 shown in Fig. 3. The charging section 6 includes a full-wave rectifier circuit 41 (the "voltage application circuit" of the present invention), a capacitor 42 (the "electricity storage device" of the present invention), a voltage detection circuit 43 (the "full charge detection section" of the present invention), switches 44a to 44d, and a control section 45. In this embodiment, the switch 44d corresponds to the "first switching section" of the present invention, and the combination of the switches 44a to 44c and the control section 45 corresponds to the "second switching section" of the present invention.

[0056] Before describing each component of the charging unit 6 in detail, the contact unit 61 in Fig. 3 will be described. The contact unit 61 is a conductive part of the take-up winder 1 that comes into contact with the traveling yarn Y. Specifically, the contact unit 61 is, for example, any one of the godet rollers 11a to 11e, the guide rollers 13, 14, the godet rollers 21, 22, the contact roller 35, the fulcrum guide 31, and the traverse guide 32. Static electricity is generated at the contact unit 61 due to friction between the traveling yarn Y and the contact unit 61.

[0057] The full-wave rectifier circuit 41 has four diodes 51a to 51d. The cathode of the diode 51a is connected to the cathode of the diode 51b. The anode of the diode 51b is connected to the cathode of the diode 51c. The anode of the diode 51c is connected to the anode of the diode 51d. The cathode of the diode 51d is connected to the anode of the diode 51a.

[0058] A connection portion 52a between the cathode of the diode 51d and the anode of the diode 51a is connected to a contact portion 61. A switch 44a is connected between the connection portion 52a and the contact portion 61. The switch 44a is switched on and off under the control of the control unit 45. When the switch 44a is in the on state, the connection portion 52a and the contact portion 61 are connected. When the switch 44a is in the off state, the connection between the connection portion 52a and the contact portion 61 is interrupted.

[0059] A connection portion 52b between the anode of the diode 51b and the cathode of the diode 51c is connected to the ground portion G and thus is grounded. In addition, the contact portion 61 is connected to the ground portion G via the switch 44b. The switch 44b is switched on and off under the control of the control portion 45. When the switch 44b is in the on state, the contact portion 61 is connected to the ground portion G and thus is grounded. When the switch 44b is in the off state, the connection of the contact portion 61 to the ground portion G is released.

[0060] The capacitor 42 is connected between a connection 52c between the cathode of the diode 51a and the cathode of the diode 51b, and a connection 52d between the anode of the diode 51c and the anode of the diode 51d. The capacitor 42 has a first terminal 42a connected to the connection 52c and a second terminal 42b connected to the connection 52d. A switch 44c is connected between the connection 52c and the first terminal 42a of the capacitor 42. The switch 44c is switched on and off under the control of the control unit 45. When the switch 44c is on, the connection 52c is connected to the first terminal 42a of the capacitor 42. When the switch 44c is off, the connection between the connection 52c and the first terminal 42a of the capacitor 42 is interrupted.

[0061] Furthermore, the first terminal 42a and the second terminal 42b of the capacitor 42 are connected to an electric device 62. The electric device 62 is, for example, a thread tension sensor, a sensor that detects the amount of static electricity generated at the contact portion 61, a bearing temperature sensor, or the like. Furthermore, a switch 44d is connected between the first terminal 42a and the electric device 62. The switch 44d is switched on and off under the control of the control unit 45. When the switch 44d is in the on state, the first terminal 42a of the capacitor 42 is connected to the electric device 62. When the switch 44d is in the off state, the connection of the first terminal 42a of the capacitor 42 with the electric device 62 is interrupted.

[0062] The voltage detection circuit 43 is connected between the first terminal 42a and the second terminal 42b of the capacitor 42. The voltage detection circuit 43 outputs a signal indicating the voltage between the first terminal 42a and the second terminal 42b to the control unit 45. When the voltage indicated by the signal output from the voltage detection circuit 43 is equal to or higher than a predetermined voltage, the control unit 45 receives this signal as a signal indicating that the capacitor 42 is fully charged. In addition, when the voltage indicated by the signal output from the voltage detection circuit 43 is less than the predetermined voltage, the control unit 45 receives this signal as a signal indicating that the capacitor 42 is not fully charged.

[0063] Here, the connection between the contact portion 61 and each part of the charging portion 6 will be described. When the contact portion 61 is the fulcrum guide 31, the fulcrum guide 31 and the charging portion 6 are connected by, for example, wiring. When the contact portion 61 is the traverse guide 32, for example, a member supporting the traverse guide 32 and the charging portion 6 are connected by wiring, thereby connecting the traverse guide 32 and the charging portion 6. When the contact portion 61 is any of the godet rollers 11a to 11e, the guide rollers 13, 14, the godet rollers 21, 22, and the contact roller 35, for example, the roller and the charging portion 6 are connected by contacting a charge removing brush connected to the charging portion 6 with the roller. Alternatively, when the contact portion 61 is any of the above rollers, for example, an electrode connected to the charging portion 6 may be spaced apart from the roller and opposed to it, thereby enabling discharge from the roller to the electrode. Even in this case, the roller and the charging portion 6 are electrically connected.

[0064] <Charging unit operation> Next, the operation of the charging unit 6 will be described. In the charging unit 6, when the voltage indicated by the signal output from the voltage detection circuit 43 is less than a predetermined voltage (the capacitor 42 is not fully charged), the control unit 45 turns on the switches 44a and 44c and turns off the switches 44b and 44d, as shown in Figures 4(a) and (b). As a result, the capacitor 42 is charged by the static electricity generated at the contact portion 61, and the static electricity generated at the contact portion 61 is removed.

[0065] More specifically, when the static charge generated at the contact portion 61 is positive, as shown in Fig. 4(a), a current flows along a path (indicated by arrow A1 in Fig. 4(a)) passing through the contact portion 61, switch 44a, connection portion 52a, diode 51a, connection portion 52c, switch 44c, capacitor 42, connection portion 52d, diode 51c, connection portion 52b, and ground portion G in this order. As a result, the charge generated at the contact portion 61 charges the capacitor 42, and the static electricity generated at the contact portion 61 is removed.

[0066] When the static charge generated at the contact portion 61 is negative, as shown in Fig. 4(b), a current flows along a path (indicated by an arrow A2 in Fig. 4(b)) passing through the ground portion G, the connection portion 52b, the diode 51b, the connection portion 52c, the switch 44c, the capacitor 42, the connection portion 52d, the diode 51d, the connection portion 52a, the switch 44a, and the contact portion 61 in this order. As a result, the capacitor 42 is charged by the charge generated at the contact portion 61, and the static electricity generated at the contact portion 61 is removed.

[0067] Here, as described above, regardless of whether the static charge generated at contact portion 61 is a positive charge or a negative charge, the first terminal 42a of capacitor 42 becomes at a higher potential than the second terminal 42b, and capacitor 42 is charged.

[0068] In addition, in the charging unit 6, when the voltage indicated by the signal output from the voltage detection circuit 43 is equal to or higher than a predetermined voltage (the capacitor 42 is fully charged), the control unit 45 turns on the switch 44b and turns off the switches 44a, 44c, and 44d, as shown in Fig. 5(a). As a result, the contact portion 61 is connected to the ground portion G and thus grounded, and static electricity generated at the contact portion 61 is removed.

[0069] In addition, in the charging section 6, when the motorized device 62 is driven, the control section 45 turns on the switches 44b and 44d and turns off the switches 44a and 44c, as shown in FIG. 5(b). As a result, the capacitor 42 and the motorized device 62 are connected, and the motorized device 62 can be driven by the charge stored in the capacitor 42. In this manner, in this embodiment, since the motorized device 62 can be driven by the charge stored in the capacitor 42, it is not necessary to connect the motorized device 62 to the power source of the take-up winder, and the motorized device 62 can be easily attached and driven as needed. In addition, at this time, the contact portion 61 is grounded by being connected to the ground portion G in order to turn on the switch 44b. This makes it possible to prevent the charge due to static electricity from continuing to accumulate in the contact portion 61 while the motorized device 62 is being driven. However, if the time for which the motorized device 62 is driven is short and the charge stored in the contact portion 61 due to static electricity while the motorized device 62 is being driven is not so large, the switch 44b may be turned off.

[0070] <Effects> In this embodiment, when the switch 44d is turned off, the capacitor 42 can be charged by the charge of static electricity generated at the contact portion 61 due to friction between the traveling yarn Y and the contact portion 61. Here, the polarity of the static electricity generated at the contact portion 61 due to friction between the yarn Y to which the oil is applied and the contact portion 61 changes depending on the type of yarn Y, the type of oil applied to the yarn Y, the brand of the oil applied to the yarn Y, changes in the surrounding environment such as humidity, etc. Therefore, in this embodiment, by connecting the full-wave rectifier circuit 41 between the contact portion 61 and the capacitor 42, when a voltage is applied between the first terminal 42a and the second terminal 42b due to the charge of static electricity generated at the contact portion 61, the first terminal 42a of the capacitor 42 has a higher potential than the second terminal 42b regardless of the polarity of the static electricity generated at the contact portion 61. This allows the capacitor 42 to be charged regardless of the polarity of the static electricity generated at the contact portion 61, and the capacitor 42 can be charged efficiently. The capacitor 42 is charged by the static electricity generated at the contact portion 61, so that the static electricity generated at the contact portion 61 can be removed.

[0071] In addition, when it is necessary to drive the electric device 62, by turning on the switch 44d while the capacitor 42 is charged and connecting the first terminal 42a of the capacitor 42 to the electric device 62, the electric charge stored in the capacitor 42 can be used to drive the electric device 62.

[0072] Generally, in the take-up winder 1 that winds the traveling yarn Y around a bobbin B to form a package P, the traveling speed of the yarn Y is high. Therefore, friction between the traveling yarn Y and the contact portion 61 is high, and a large amount of static electricity is generated at the contact portion 61. In this embodiment, the capacitor 42 is charged by the static electricity generated at the contact portion 61 of the take-up winder 1, in which the traveling speed of the yarn Y is high, so that the capacitor 42 can be efficiently charged. Furthermore, by charging the capacitor 42, the large amount of static electricity generated at the contact portion 61 can be removed.

[0073] The godet rollers 11a-11e, guide rollers 13, 14, and godet rollers 21, 22 that transport the multiple yarns Y each generate static electricity due to friction with the multiple yarns Y, and the total amount of static electricity generated is large. Therefore, when any of these rollers is used as the contact portion 61 and the capacitor 42 is charged by the static charge generated on this roller, the capacitor 42 can be efficiently charged. Also, by charging the capacitor 42, the large amount of static electricity generated on this roller can be removed.

[0074] Furthermore, the godet rollers 11a to 11e, the guide rollers 13, 14, and the godet rollers 21, 22, which transport the multiple yarns Y, transport the yarns Y while gripping them. The rotation speed of any one of these rollers may be adjusted to adjust the tension of the traveling yarn Y. In this embodiment, the degree to which the roller grips the yarn Y, in other words, the degree of slippage between the roller and the yarn Y, can be detected based on the charge of the capacitor 42 caused by the static electricity generated in the roller.

[0075] Furthermore, since the contact roller 35 rotates while in contact with the yarn Y located on the surface of the package P being wound, static electricity is generated on the contact roller 35. Furthermore, in the present embodiment, since the contact roller 35 rotates while in contact with the yarn Y located on the surfaces of multiple packages P, the total amount of static electricity generated is large. Therefore, when the contact roller 35 is used as the contact portion 61 and the capacitor 42 is charged by the charge of static electricity generated on the contact roller 35, the capacitor 42 can be efficiently charged. Furthermore, by charging the capacitor 42, static electricity generated on the contact roller 35 can be removed.

[0076] In addition, since the winding detection unit 36, which detects the winding of the yarn Y around the contact roller 35, is disposed close to the contact roller 35, when static electricity is generated on the contact roller 35, discharge is likely to occur between the contact roller 35 and the winding detection unit 36. Therefore, when the contact roller 35 is used as the contact unit 61 and the capacitor 42 is charged by the charge of static electricity generated on the contact roller 35, discharge between the contact roller 35 and the winding detection unit 36 ​​can be suppressed by removing the static electricity on the contact roller 35.

[0077] The traverse guide 32 of the traverse device 30 generates static electricity due to friction with the traveling yarn Y. Therefore, when the traverse guide 32 is used as the contact portion 61 and the capacitor 42 is charged with the charge of the static electricity generated in the traverse guide 32, the static electricity generated in the traverse guide 32 can be removed.

[0078] The fulcrum guide 31 of the traverse device 30 generates static electricity due to friction with the traveling yarn Y. In addition, since the fulcrum guide 31 is a fulcrum for traverse, the bending angle of the yarn Y is larger than that of other fixed guides, and the static electricity generated is large. Therefore, when the fulcrum guide 31 is used as the contact portion 61 and the capacitor 42 is charged with the charge of the static electricity generated in the fulcrum guide 31, the large static electricity generated in the fulcrum guide 31 can be removed and the capacitor 42 can be efficiently charged. In addition, in this embodiment, the fulcrum guide 31 is provided for each of the multiple yarns Y. As a result, yarn breakage can be detected based on whether the capacitor 42 is charged by the static electricity generated in the fulcrum guide 31 (whether static electricity is generated in the fulcrum guide 31).

[0079] Furthermore, since the fulcrum guide 31 does not move in accordance with the running of the yarn Y, friction with the running yarn Y is greater and static electricity is generated greater than with the godet rollers 11a-11e, guide rollers 13, 14, godet rollers 21, 22, contact roller 35, etc., which rotate in accordance with the running of the yarn Y. Therefore, when the capacitor 42 is charged by the static electricity generated in the fulcrum guide 31 using the fulcrum guide 31 as the contact portion 61, the capacitor 42 can be efficiently charged. Furthermore, by charging the capacitor 42, the large static electricity generated in the fulcrum guide 31 can be removed.

[0080] In this embodiment, the oil supply guide 10 is disposed upstream of the contact portion 61 in the running direction of the yarn Y, regardless of whether the contact portion 61 is one of the godet rollers 11a to 11e, the guide rollers 13 and 14, the godet rollers 21 and 22, the contact roller 35, the fulcrum guide 31, or the traverse guide 32. The polarity of static electricity generated at the contact portion 61 due to friction between the yarn Y to which the oil is applied and the contact portion 61 may change depending on the brand and type of oil applied to the yarn Y in the oil supply guide 10, changes in the surrounding environment such as humidity, etc. In this embodiment, by connecting the full-wave rectifier circuit 41 between the contact portion 61 and the capacitor 42, when a voltage is applied between the first terminal 42a and the second terminal 42b of the capacitor 42 due to the charge of static electricity generated at the contact portion 61, the first terminal 42a has a higher potential than the second terminal 42b, regardless of the polarity of the static electricity generated at the contact portion 61. As a result, even if the polarity of the static electricity generated at the contact portion 61 changes due to variations in the degree to which the oil applied to the yarn Y adheres, the charging of the capacitor 42 can be continued.

[0081] In this embodiment, when the capacitor 42 is not fully charged, the contact portion 61 is connected to the full-wave rectifier circuit 41, so that the capacitor 42 can be charged by the static electricity generated at the contact portion 61. On the other hand, when the capacitor 42 is fully charged, the contact portion 61 is grounded, so that the static electricity generated at the contact portion 61 can be released to the outside.

[0082] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various modifications are possible within the scope of the claims.

[0083] For example, in the above embodiment, one capacitor 42 is charged by the static electricity generated at one contact portion 61, but the present invention is not limited to this.

[0084] For example, two or more of the godet rollers 11a to 11e, guide rollers 13, 14, godet rollers 21, 22, contact roller 35, fulcrum guide 31, and traverse guide 32 may each be a contact portion 61, and a charging portion 6 similar to that of the above-described embodiment may be provided for each contact portion 61.

[0085] In addition, when there are a plurality of contact parts 61, the present invention is not limited to providing a charging part 6 for each of the contact parts 61. In the first modification, as shown in Fig. 6, in the charging part 70, a plurality of contact parts 61 are connected in parallel to the connection part 52a. Each of the plurality of contact parts 61 is one of the godet rollers 11a to 11e, the guide rollers 13, 14, the godet rollers 21, 22, the contact roller 35, the fulcrum guide 31, and the traverse guide 32. In addition, a switch 44a is connected between the connection part 52a and each of the contact parts 61.

[0086] In the case of the first modification, when the voltage indicated by the signal output from the voltage detection circuit 43 is less than a predetermined voltage, the control unit 45 turns on one switch 44a and switch 44c among the multiple switches 44a, and turns off the other switches 44a among the multiple switches 44a, as well as switches 44b and 44d. At this time, the control unit 45 switches one switch 44a to be turned on among the multiple switches 44a, for example, at regular intervals.

[0087] In the case of the first modification, the capacitor 42 is charged by the static electricity generated at the plurality of contact portions 61, and the static electricity generated at the plurality of contact portions 61 can be removed by charging the capacitor 42.

[0088] 7, in the charging section 80, a plurality of capacitors 42 are connected in parallel between the connection section 52c and the connection section 52d. A switch 44c is connected between the connection section 52c and the first terminal 42a of each of the capacitors 42. A voltage detection circuit 43 is connected between the first terminal 42a and the second terminal 42b of each of the capacitors 42.

[0089] In the case of the second modification, when the voltage indicated by the signal output from one or more voltage detection circuits 43 is less than the predetermined voltage (there is another capacitor 42 that is not fully charged), the control unit 45 turns on the switch 44a and one of the one or more switches 44c corresponding to the one or more voltage detection circuits 43, and turns off the switches 44b, 44d, and the switches 44c other than the one switch 44c among the multiple switches 44c. After turning on a certain switch 44c, when the voltage indicated by the signal output from the voltage detection circuit 43 corresponding to this switch 44c becomes equal to or greater than the predetermined voltage (the capacitor 42 corresponding to this switch 44c is fully charged), the control unit 45 turns off this switch 44c. Furthermore, when the voltage indicated by the signal output from another voltage detection circuit 43 is less than the predetermined voltage (there is another capacitor 42 that is not fully charged), the control unit 45 turns on the switch 44c corresponding to the other voltage detection circuit 43.

[0090] On the other hand, when the voltages indicated by the signals output from all the voltage detection circuits 43 are equal to or higher than the predetermined voltage (all the capacitors 42 are fully charged), the switches 44a, 44d and the multiple switches 44c are turned off, and the switch 44b is turned on. In the case of the second modification, by turning on one switch 44c of the multiple switches 44c and the switches 44b, 44d, and turning off the switch 44a and the switches 44c other than the one switch 44c of the multiple switches 44c, the electric device 62 can be driven by the charge stored in the capacitor 42 corresponding to the one switch 44c.

[0091] In the case of the second modification, the plurality of capacitors 42 can be charged by the static electricity generated at the contact portion 61. Then, the electric charge stored in the plurality of capacitors 42 can drive the electric device 62.

[0092] In addition to being provided with a plurality of contact parts 61 and a plurality of switches 44a in the charging section as in Modification 1, a plurality of capacitors 42, a plurality of switches 44c, and a plurality of voltage detection circuits 43 may be provided as in Modification 2. In this case, the plurality of capacitors 42 can be charged by the electric charge generated at the plurality of contact parts 61, and the electric charge stored in the plurality of capacitors 42 can drive the electric device 62.

[0093] In the above embodiment, the full-wave rectifier circuit 41 is connected between the contact portion 61 and the capacitor 42, and a voltage is applied between the first terminal 42a and the second terminal 42b so that the first terminal 42a has a higher potential than the second terminal 42b due to the charge of static electricity generated at the contact portion 61, regardless of the polarity of the static electricity, but this is not limited to the above. A voltage application circuit other than the full-wave rectifier circuit 41 may be connected between the contact portion 61 and the capacitor 42, and a voltage may be applied between the first terminal 42a and the second terminal 42b so that the first terminal 42a has a higher potential than the second terminal 42b due to the charge of static electricity generated at the contact portion 61, regardless of the polarity of the static electricity.

[0094] 8, in the third modification, a charging unit 100 includes a voltage application circuit 101 instead of the full-wave rectifier circuit 41 in the charging unit 6 of the above embodiment. The charging unit 100 also includes a voltage detection circuit 102.

[0095] The voltage application circuit 101 has four switches 111a to 111d. The switch 111a is connected between a terminal of the switch 44a opposite to the contact portion 61 and a terminal of the switch 44c opposite to the capacitor 42. The switch 111b is connected between a terminal of the switch 44a opposite to the contact portion 61 and a second terminal 42b of the capacitor 42. The switch 111c is connected between a terminal of the switch 44c opposite to the capacitor 42 and a ground G. The switch 111d is connected between the second terminal 42b of the capacitor 42 and a ground G. The switches 111a to 111d are switched on and off by the control unit 45. In the third modification, the switch 44d corresponds to the "first switching unit" of the present invention, and the combination of the switches 44a to 44c, 111a to 111d and the control unit 45 corresponds to the "second switching unit" of the present invention.

[0096] The voltage detection circuit 102 is connected between the contact portion 61 and the ground portion G, and outputs a signal indicating the potential of the contact portion 61 relative to the potential of the ground portion G (ground potential) to the control portion 45. When the static charge generated in the contact portion 61 is positive, the signal output from the voltage detection circuit 102 indicates a positive potential higher than the ground potential. When the static charge generated in the contact portion 61 is negative, the signal output from the voltage detection circuit 102 indicates a negative potential lower than the ground potential.

[0097] In variant example 3, when the voltage indicated by the signal output from the voltage detection circuit 43 is less than a predetermined voltage (when the capacitor 42 is not fully charged), the control unit 45 turns on switches 44a and 44c and turns off switches 44b and 44d, as shown in Figures 9(a) and (b).

[0098] Furthermore, when the signal output from the voltage detection circuit 102 indicates a positive potential, that is, when the static charge generated at the contact portion 61 is a positive charge, the control portion 45 turns on the switches 111a and 111d and turns off the switches 111b and 111c, as shown in Fig. 9(a). Then, a current flows along a path (indicated by an arrow A3 in Fig. 9(a)) passing through the contact portion 61, the switch 44a, the switch 111a, the switch 44c, the capacitor 42, the switch 111d, and the ground portion G in this order. As a result, the static electricity generated at the contact portion 61 is removed, and the capacitor 42 is charged by the static charge generated at the contact portion 61.

[0099] On the other hand, when the signal output from the voltage detection circuit 102 indicates a negative potential, that is, when the static charge generated at the contact portion 61 is negative, the control unit 45 turns on the switches 111b and 111c and turns off the switches 111a and 111d, as shown in Fig. 9(b). Then, a current flows along a path (indicated by an arrow A4 in Fig. 9(b)) passing through the ground portion G, the switch 111c, the switch 44c, the capacitor 42, the switch 111b, the switch 44a, and the contact portion 61 in this order. As a result, the static electricity generated at the contact portion 61 is removed, and the capacitor 42 is charged by the static charge generated at the contact portion 61.

[0100] Also in the case of the third modification, regardless of the polarity of the static electricity generated at the contact portion 61, the first terminal 42a of the capacitor 42 has a higher potential than the second terminal 42b.

[0101] In the above embodiment, the switches 44a to 44d are turned on and off under the control of the control unit 45, but this is not limiting. For example, the charging unit 6 may have a circuit that turns on and off at least some of the switches 44a to 44d.

[0102] For example, the charging unit 6 may have an IC for charging control, and this IC may switch the states of the switches 44a to 44d between those shown in Figures 4(a) and (b) and the state shown in Figure 5(a) depending on whether the capacitor 42 is fully charged or not.

[0103] In the above embodiment, when the voltage indicated by the signal output from the voltage detection circuit 43 is equal to or higher than the predetermined voltage (the capacitor 42 is fully charged), the contact portion 61 is grounded by being connected to the ground portion G, but this is not limited thereto. When the voltage indicated by the signal output from the voltage detection circuit 43 is equal to or higher than the predetermined voltage, the switches 44a, 44c may be turned off and the contact portion 61 may not be grounded.

[0104] In addition, in the above-described embodiment, the take-up winder 1 is equipped with a winding detection unit 36 ​​for detecting winding of the yarn Y around the contact roller 35, but the take-up winder 1 does not necessarily have to be equipped with the winding detection unit 36.

[0105] In the above embodiment, the contact portion 61 is any one of the godet rollers 11a to 11e, the guide rollers 13 and 14, the godet rollers 21 and 22, the contact roller 35, the fulcrum guide 31, and the traverse guide 32, but is not limited thereto. For example, the take-up winder 1 may have another part as the contact portion 61 that is conductive and contacts the traveling yarn Y. In this case, the contact portion 61 may be a stationary guide other than the fulcrum guide 31.

[0106] In the above embodiment, the take-up winder 1 includes the oil supply guide 10, and the contact portion 61 is a member located downstream of the oil supply guide 10 in the running direction of the yarn Y, but this is not limited to the above. For example, the take-up winder 1 may include another portion that has a conductive material and contacts the running yarn Y as the contact portion 61, located upstream of the oil supply guide 10 in the running direction of the yarn. Alternatively, the take-up winder 1 does not need to include the oil supply guide 10.

[0107] In the above example, the capacitor 42 is charged with the static electricity generated at the contact portion 61, but this is not limited to the above. For example, a battery may be provided instead of the capacitor 42, and the battery may be charged with the static electricity generated at the contact portion 61. In this case, the battery corresponds to the "electricity storage device" of the present invention.

[0108] In the above, an example in which the present invention is applied to a take-up winder that winds the traveling yarn Y to form a package has been described, but the present invention is not limited to this. The present invention can also be applied to yarn processing equipment other than a take-up winder.

[0109] Further, in the above description, an example has been described in which the electric device constituting the yarn processing equipment is driven by the electric charge stored in a capacitor or the like included in the yarn processing equipment, but the present invention is not limited to this.

[0110] In the fourth modification, as shown in FIG. 10, the yarn processing equipment system 200 includes a plurality of yarn processing equipment 201 and one electric device 202. The plurality of yarn processing equipment 201 are, for example, the take-up winder 1 of the above-mentioned embodiment, with the electric device 62 removed. The plurality of yarn processing equipment 201 are, for example, installed in the same building. The plurality of yarn processing equipment 201 may be the same type of equipment or different types of equipment. Note that, although FIG. 10 shows a case where the yarn processing equipment system 200 includes three yarn processing equipment 201, the number of yarn processing equipment 201 constituting the yarn processing equipment system 200 may be two or four or more. Also, in FIG. 10, the configuration of the yarn processing equipment 201 other than the capacitor 42 and the switch 44d is omitted from the illustration.

[0111] The electrically powered device 202 is a device separate from the devices constituting the yarn processing facility 201, for example, a device installed in a building separate from the building in which the yarn processing facility 201 is installed.

[0112] In the yarn processing equipment system 200, a first terminal 42a of the capacitor 42 of each yarn processing equipment 201 is connected to one terminal of the motorized device 202 via a switch 44d, and a second terminal 42b of the capacitor 42 of each yarn processing equipment 201 is connected to the other terminal of the motorized device 202. When the switch 44d of the yarn processing equipment 201 is turned on while the capacitor 42 of the yarn processing equipment 201 is in a charged state, the motorized device 202 is driven by the charge stored in the capacitor 42. That is, in the fourth modification, the motorized device 202 is driven by the charge stored in the capacitors 42 of the multiple yarn processing equipment 201. In the fourth modification, the switch 44d corresponds to the "switching unit" of the present invention.

[0113] In the fourth modification, as in the above embodiment, in each yarn processing equipment 201, when the switch 44d is turned off, the capacitor 42 can be charged by the charge of static electricity generated at the contact part due to friction between the traveling yarn Y and the contact part, regardless of the polarity of the static electricity generated at the contact part. Then, the static electricity generated at the contact part can be removed by charging the capacitor 42 by the charge of static electricity generated at the contact part.

[0114] In addition, in the fourth variant, when it is necessary to drive the electric device 202, by turning on the switch 44d while the capacitor 42 is charged, the electric charge stored in the capacitor 42 can be used to drive the electric device 202.

[0115] In addition, in the fourth variant, one electric device 202 is driven using the electric charge stored in the capacitors 42 of multiple yarn processing equipment 201. Therefore, even if the amount of electric charge stored in the capacitors 42 of each yarn processing equipment 201 is not particularly large, the electric device 202 can be driven as long as the total amount of electric charge is relatively large.

[0116] In the fourth modified example, the yarn processing equipment system 200 includes a plurality of yarn processing equipment 201 and one power supply device 202, and one electric device 202 is driven by electric charges stored in the capacitors 42 of the plurality of yarn processing equipment 201, but this is not limited to the above. The yarn processing equipment system may be configured with one yarn processing equipment and one electric device provided outside the yarn processing equipment, and one electric device may be driven by electric charges stored in the capacitors 42 of the one yarn processing equipment.

[0117] In the above example, the switch 44d is connected between the first terminal 42a of the capacitor 42 and the electrically-driven device 62, 202, but this is not limited thereto. The switch 44d may be connected between the second terminal 42b of the capacitor 42 and the electrically-driven device 62, 202.

[0118] Furthermore, in the above examples, the electric device may be connected to another power source such as a commercial power source in addition to being connected to the power storage device of the yarn processing equipment. The electric device may be driven by the charge stored in the power storage device of the yarn processing equipment and the charge supplied from the other power source. In this case, if the power storage device of the yarn processing equipment has a sufficient charge, the electric device may be driven only by the charge stored in the power storage device. In this way, when the electric device is driven by the charge stored in the power storage device of the yarn processing equipment and the charge supplied from the other power source, it is possible to reduce power consumption in the other power source and to drive the electric device even when the power storage device of the yarn processing equipment cannot supply a sufficient charge to the electric device.
