Summary of the Invention

Problems to be Solved by the Invention

[0004] The above motor is generally driven and controlled by, for example, a motor driver. An electronic device such as a motor driver is provided on, for example, a control board of the unit controller. Further, compressed air (compressed gas) is supplied to the air spinning device. The supply state of the compressed gas is adjusted by, for example, a solenoid valve. Generally, a hose through which the compressed gas flows is connected to the solenoid valve. Here, for example, when a problem such as the hose of the solenoid valve comes off during the operation of the spinning unit occurs, depending on the arrangement of the control board, there is a possibility that the compressed gas is unintentionally jetted to the control board through the hose. As a result, there is a risk of adverse effects on the control board. <00000​The objective of the present invention is to suppress adverse effects on the control board caused by compressed gas in a winding device. [Means for solving the problem]

[0006] The first winding device is a winding device that winds up yarn to form a package, and is connected to a compressed gas source that supplies compressed gas, and comprises an injection unit that injects the compressed gas, an adjustment unit that adjusts the supply state of the compressed gas to the injection unit, a control board that controls the adjustment unit, and an installation unit on which the adjustment unit and the control board are provided, wherein the installation unit has a partition that separates a first region on which the control board is provided and a second region on which the adjustment unit is provided.

[0007] In this invention, when a malfunction occurs in the adjustment section, the partition section prevents compressed gas from being accidentally sprayed onto the control board. Therefore, in the winding device, adverse effects of compressed gas on the control board can be suppressed.

[0008] The winding device of the second invention is characterized in that, in the first invention, it comprises a heating element provided on the control board that generates heat when an electric current is applied, and a heat sink provided between the control board and the installation portion in the thickness direction of the control board that dissipates the heat generated by the heating element toward the installation portion, wherein the heat sink has a protrusion that protrudes toward the control board in the thickness direction and at least partially overlaps with the heating element when viewed from the thickness direction.

[0009] When the heat sink is flat, the distance between the heat sink and electronic devices other than the heat source on the control board becomes small in the thickness direction. As a result, heat can easily be exchanged between the heat sink and the electronic devices other than the heat source on the control board. This can lead to heat from the heat source being transferred to the other electronic devices, potentially causing them to be unintentionally heated. In this invention, heat from the heat source can be dissipated to the heat sink via the protrusions, and the transfer of heat from the heat sink to other electronic devices can be avoided. Therefore, it is possible to suppress the unintentional heating of electronic devices.

[0010] The winding device of the third invention is characterized in that, in the first or second invention, it comprises a plurality of pairs of draft rollers arranged in the direction of movement of the sliver, each configured to sandwich and stretch the sliver which is the raw material for the yarn, a plurality of drive units controlled by the control board to drive each of the plurality of pairs of draft rollers, and a frame member that supports the plurality of pairs of draft rollers, wherein the installation unit is attached to the frame member.

[0011] In this invention, a control board can be provided near multiple drive units that are to be controlled. Therefore, the wiring from the control board to the controlled units can be shortened.

[0012] The winding device of the fourth invention is configured in any of the first to third inventions to sandwich and stretch the sliver which is the raw material for the yarn, and comprises a plurality of pairs of draft rollers arranged in the direction of movement of the sliver, a winding section that forms the package at a position below the plurality of pairs of draft rollers, a support section that is arranged upstream of the plurality of pairs of draft rollers in the direction of movement and above the plurality of pairs of draft rollers and supports the sliver, a frame member that supports the plurality of pairs of draft rollers, and a fixing section that is arranged below the support section and to which the frame member is fixed, wherein the installation section is arranged in the space between the support section and the fixing section in the vertical direction.

[0013] In this invention, a space is formed between the support portion and the fixing portion in the vertical direction. This space can be used to position the installation portion. Therefore, space savings can be achieved compared to configurations where the installation portion is located elsewhere.

[0014] The winding device of the fifth invention is characterized in that, in the fourth invention, the installation part comprises an installation part body on which the control board is provided, and a lid that can be moved between an operating position for moving the sliver downstream in the direction of movement and an exposed position for exposing the control board to the outside, and the support part is provided to move integrally with the lid.

[0015] Moving the cover to an exposed position makes it easier for workers to access the work board. Therefore, maintenance near the main body of the installation unit can be easily performed when the cover is in the exposed position. In this invention, the support part moves integrally with the cover. When the support part is in a position different from the operating position, it is difficult to support the sliver in the same way as during normal operation. For this reason, the winding device is not usually operated when the cover is in the exposed position. This prevents the control board from operating when the cover is in the exposed position. Therefore, the possibility of a worker accidentally touching the control board while it is in operation is reduced, and the safety of the winding device can be improved.

[0016] The winding device of the sixth invention is characterized in that, in any of the third to fifth inventions, the control board is electrically connected to a power source via the back surface of the installation portion located on the side opposite to the plurality of draft roller pairs, and is electrically connected to a plurality of drive units that drive the plurality of draft roller pairs via the front surface of the installation portion located on the side of the plurality of draft roller pairs.

[0017] In this invention, since the wiring extends from the back to the front of the installation unit, the layout in the vicinity of the installation unit can be simplified.

[0018] The winding device of the seventh invention is characterized in that, in any of the third to sixth inventions, it comprises a first pipe extending on the opposite side from the plurality of draft roller pairs across the installation portion and connecting the compressed gas source and the adjustment portion, and a second pipe extending on the plurality of draft roller pairs side from the installation portion and connecting the adjustment portion and the injection portion.

[0019] In the present invention, the first pipe and the second pipe extend on opposite sides of each other with the installation part therebetween. Therefore, the layout in the vicinity of the installation part can be simplified.

[0020] The take-up device according to the eighth invention is characterized in that, in the seventh invention, the connection position between the adjustment part and the second pipe is below the connection position between the adjustment part and the first pipe, and the injection part is located below the adjustment part.

[0021] In the present invention, the second pipe extends in a direction considering the positional relationship between the adjustment part and the injection part. Therefore, the bending of the second pipe can be suppressed.

[0022] The take-up device according to the ninth invention is characterized in that, in the seventh or eighth invention, the adjustment part is provided on the front surface of the installation part on the opposite side of the plurality of draft roller pairs, the inclination angle of the virtual line segment connecting the inlet and the outlet of the adjustment part with respect to the arrangement direction in which the plurality of draft roller pairs are arranged is 0 degree or more and 30 degrees or less, and the injection part is located below the adjustment part.

[0023] Also in the present invention, the layout in the vicinity of the installation part can be simplified.

[0024] The take-up device according to the tenth invention is characterized in that, in any one of the seventh to ninth inventions, the adjustment part is provided on the front surface of the installation part on the opposite side of the plurality of draft roller pairs, the second pipe extends along the arrangement direction in which the plurality of draft roller pairs are arranged, and the injection part is located below the adjustment part.

[0025] Also in the present invention, the layout in the vicinity of the installation part can be simplified.

[0026] The take-up device of the 11th invention is characterized in that, in any one of the 1st to 10th inventions, it includes a plurality of the adjustment parts, a manifold provided between the compressed gas source and the plurality of adjustment parts in the supply direction in which the compressed gas is supplied, and having a distribution part for distributing the compressed gas to the plurality of adjustment parts, and a filter provided on the manifold and arranged upstream of the distribution part in the supply direction.

[0027] In the present invention, it is possible to effectively suppress the intrusion of particles into a plurality of adjustment parts via the manifold.

[0028] The take-up device of the 12th invention is characterized in that, in the 11th invention, it includes a plurality of the injection parts connected to the manifold, the plurality of injection parts include a spinning part for generating the yarn, one of the plurality of adjustment parts adjusts the supply state of the compressed gas to the spinning part, and the remaining of the plurality of adjustment parts are respectively connected to one or more injection parts that intermittently receive the supply of the compressed gas among the plurality of injection parts.

[0029] The adjustment part that adjusts the supply state of the compressed gas to the spinning part is basically used during normal spinning, and the remaining adjustment parts are used intermittently (i.e., only temporarily). Therefore, even if the compressed gas is distributed by the manifold, it is possible to suppress the disturbance of the supply state of the compressed gas to the spinning part.

[Figure 3] It is a side view of the upper end part of the spinning unit. [Figure 4] (a) and (b) are front views of the unit controller. [Figure 5] (a) is a view taken in the direction of arrow V(a) in FIG. 4(a), and (b) is a view taken in the direction of arrow V(b) in FIGs. ((b). [Figure 6]This is a cross-sectional view taken along the line VI-VI in Figure 4(b). [Figure 7] This is a bottom view of the manifold. [Modes for carrying out the invention]

[0031] Embodiments of the present invention will now be described. In Figure 1, the left-right direction is defined as the left-right direction. In Figure 1, the up-down direction is defined as the up-down direction (the vertical direction in which gravity acts). In Figure 1, the vertical direction (the left-right direction in Figure 2) is defined as the front-back direction.

[0032] (Air spinning machine) The schematic configuration of the air spinning machine 1 according to this embodiment will be described with reference to Figure 1. Figure 1 is a front view of the air spinning machine 1. As shown in Figure 1, the air spinning machine 1 comprises, for example, a plurality of spinning units 2 (winding devices of the present invention), a yarn splicing trolley 3, a first end frame 4, and a second end frame 5.

[0033] Each spinning unit 2 generates yarn Y and winds it onto a bobbin B to form a package P. Multiple spinning units 2 are arranged, for example, in the left-right direction. Multiple spinning units 2 can be divided, for example, into multiple unit groups. Each unit group consists of, for example, two spinning units 2 (see Figure 1) arranged side by side in the left-right direction. These two spinning units 2 are configured to be approximately symmetrical in the left-right direction. The yarn splicing cart 3 splices yarn in a spinning unit 2 when the yarn Y is interrupted for any reason. When a package P is full, it is lifted by a hoisting cart (not shown).

[0034] The first end frame 4 houses, for example, a recovery device (not shown) for collecting fiber waste generated in the spinning unit 2. The second end frame 5 houses, for example, a machine stand control device 5a and a compressed air source 5b (compressed gas source of the present invention). The machine stand control device 5a comprehensively controls the air spinning machine 1. The compressed air source 5b supplies compressed air (compressed gas of the present invention) to each part of the air spinning machine 1. Alternatively, the compressed air source 5b may be located in a place other than inside the second end frame 5. The compressed air source 5b may be located, for example, outside the space in which the air spinning machine 1 is installed.

[0035] (Spinning Unit) The configuration of the spinning unit 2 will be explained with reference to Figures 1 to 3. Figure 2 is a side view of the spinning unit 2. Figure 3 is a side view of the upper end of the spinning unit 2.

[0036] As shown in Figures 1 and 2, each spinning unit 2 includes a drafting device 6, an air spinning device 7 (the jetting and spinning sections of the present invention), a yarn monitoring device 8, a tension sensor 9, a yarn storage device 11, a waxing device 12, and a winding unit 13. These components are arranged in this order from the upstream side in the direction of yarn Y travel. In this embodiment, for example, one unit controller 10 is provided for every two spinning units 2 (i.e., one unit group) (see Figure 1). Each unit controller 10 controls the operation of the two corresponding spinning units 2.

[0037] The drafting device 6 is configured to stretch the sliver S, which is the raw material for the yarn Y, while moving it. The sliver S is a long, strip-shaped material composed of numerous short fibers. The drafting device 6 has, in order from upstream in the direction of movement of the sliver S, a back roller pair 14, a third roller pair 15, a middle roller pair 16, and a front roller pair 17. The back roller pair 14, the third roller pair 15, the middle roller pair 16, and the front roller pair 17 will hereafter be referred to as multiple draft roller pairs. The multiple draft roller pairs are arranged, for example, in a line from upstream to diagonally downward and forward in the direction of movement of the sliver S. For convenience of explanation, the direction in which the multiple draft roller pairs are arranged will be referred to as the arrangement direction (see Figure 3).

[0038] The back roller pair 14 has a bottom roller 14a and a top roller 14b. The third roller pair 15 has a bottom roller 15a and a top roller 15b. The middle roller pair 16 has a bottom roller 16a and a top roller 16b. The front roller pair 17 has a bottom roller 17a and a top roller 17b. Each of the bottom rollers 14a, 15a, 16a, and 17a is rotatably supported on a frame member 41 (see Figure 3). The lower end of the frame member 41 is fixed, for example, to a fixing member 42 (the fixing part of the present invention; see Figure 3) that extends in the left-right direction. Each of the top rollers 14b, 15b, 16b, and 17b is rotatably supported on another frame (not shown) that is pivotably attached to the frame member 41. Each of the bottom rollers 14a, 15a, 16a, and 17a is rotationally driven by a motor (not shown) provided on each spinning unit 2. Each draft roller pair feeds the sliver S downstream in the direction of travel of the sliver S by sandwiching it between the bottom roller (not shown) and the top roller (not shown). The bottom roller 16a of the middle roller pair 16 is provided with an apron belt 18a. The top roller 16b of the middle roller pair 16 is provided with an apron belt 18b. The apron belt 18a is moved back and forth (traversed) in the left-right direction by, for example, a motor (not shown). This motor is provided in common for the two spinning units 2.

[0039] In the direction of movement of the sliver S, a sliver support portion 19 (the support portion of the present invention; see Figures 2 to 4(b)) is positioned upstream of the draft device 6. The sliver support portion 19 supports the sliver S and guides it to the draft device 6. The sliver support portion 19 is configured, for example, to be non-rotatable. The sliver support portion 19 has, for example, a contact portion 19t, a pair of wall portions 19w, and a column portion 19p (see Figure 4(a)). The contact portion 19t contacts the sliver S from below to support and guide the sliver S in the front-rear direction. The pair of wall portions 19w are positioned on both sides of the contact portion 19t in the left-right direction. The pair of wall portions 19w prevent the sliver S from falling off the contact portion 19t. The column portion 19p supports the contact portion 19t. The column portion 19p is attached to the installation portion 51, which will be described later. The sliver support portion 19 is positioned above the fixing member 42 described above. In other words, the fixing member 42 is positioned below the sliver support portion 19. Further upstream of the sliver support portion 19 in the direction of movement of the sliver S, a sliver support portion 20 (see Figure 3; support portion of the present invention) having the same configuration as the sliver support portion 19 is also provided.

[0040] The pneumatic spinning apparatus 7 twists the sliver S (fiber bundle F) stretched by the drafting apparatus 6 with a swirling airflow. This spins the fiber bundle F to produce yarn Y. The pneumatic spinning apparatus 7 is connected to a compressed air source 5b via, for example, solenoid valves 43 and 44 (see schematic diagram in Figure 2). More specifically, as shown in Figure 2, the pneumatic spinning apparatus 7 has a spinning nozzle 7a (the injection and spinning section of the present invention) and a draw-in section 7b (the injection section of the present invention). The spinning nozzle 7a is the part that spins using compressed air to produce yarn Y. The spinning nozzle 7a is connected to the compressed air source 5b via a solenoid valve 43. Compressed air is constantly supplied to the spinning nozzle 7a when yarn Y is being produced. The draw-in section 7b is the part that draws the sliver S (fiber bundle F) into the pneumatic spinning apparatus 7 using compressed air when spinning is started (or resumed after a temporary interruption). In other words, the intake section 7b is one of the multiple injection sections (one or more injection sections of the present invention) that intermittently receives compressed air. The intake section 7b is connected to the compressed air source 5b via a solenoid valve 44.

[0041] The yarn monitoring device 8 is positioned between the air spinning machine 7 and the yarn storage device 11 in the direction of yarn Y's movement. Based on information obtained by monitoring the moving yarn Y, the yarn monitoring device 8 detects the presence or absence of yarn defects. When the yarn monitoring device 8 detects a yarn defect, it transmits a detection signal to the unit controller 10. The tension sensor 9 is positioned between the air spinning machine 7 and the yarn storage device 11 in the direction of yarn Y's movement. The tension sensor 9 measures the tension of the moving yarn Y and transmits a tension measurement signal to the unit controller 10. Based on the detection results from the yarn monitoring device 8 and the tension sensor 9, the unit controller 10 determines whether or not there is an abnormality in the yarn Y. When it is determined that there is an abnormality in the yarn Y, the yarn Y is cut. Specifically, for example, the supply of compressed air to the air spinning machine 7 is stopped, interrupting the production of yarn Y, and thus the yarn Y is cut. Alternatively, a cutter (not shown) for cutting the yarn Y may be provided.

[0042] The yarn storage device 11 is positioned between the air spinning machine 7 and the winding unit 13 in the direction of yarn Y's travel. The yarn storage device 11 is configured to temporarily store the yarn Y. The waxing device 12 is positioned between the yarn storage device 11 and the winding unit 13 in the direction of yarn Y's travel and applies wax to the yarn Y.

[0043] The winding unit 13 winds the yarn Y onto the bobbin B to form the package P. The winding unit 13 is located at the lowest part of the spinning unit 2 (i.e., below the multiple pairs of draft rollers). The winding unit 13 has a cradle arm 21, a winding drum 22, and a traverse guide 23. The cradle arm 21 rotatably supports the bobbin B. The cradle arm 21 is pivotably supported by a support shaft 24, and brings the surface of the bobbin B or the surface of the package P into contact with the surface of the winding drum 22 with appropriate pressure. The winding drum 22 is rotationally driven by a motor (not shown). The traverse guide 23 is reciprocated by a motor (not shown). As a result, the winding unit 13 winds the yarn Y onto the package P while traversing it. Motors for the winding drum 22 and the traverse guide 23 are provided, for example, for each spinning unit 2.

[0044] In the direction of travel of the yarn Y, a suction device 26 is provided between the yarn storage device 11 and the winding unit 13. The suction device 26 sucks and holds the yarn Y on the winding unit 13 side when the yarn Y is cut. The suction device 26 has a suction port 26a for sucking the yarn Y and a shutter 26b for opening and closing the suction port 26a. The shutter 26b is driven to open and close by, for example, an air cylinder 26c. The suction device 26 is connected to, for example, a suction source (not shown). The air cylinder 26c is connected to a compressed air source 5b via a solenoid valve 45. The air cylinder 26c receives compressed air intermittently. That is, the air cylinder is used only at the start of the suction holding of the yarn Y by the suction device 26 and at the end of the suction holding of the yarn Y by the suction device 26. The piping (not shown) that supplies compressed air to the air cylinder 26c corresponds to the injection unit of the present invention.

[0045] Examples of injection units that intermittently receive compressed air include the following: A first cleaning unit (not shown) is provided for cleaning multiple units, including the air spinning machine 7 and the drafting machine 6. A second cleaning unit (not shown) is provided for cleaning the yarn storage device 11 and the suction port 26a. The first and second cleaning units are used temporarily, for example, when yarn breakage occurs. The first and second cleaning units also correspond to the injection units of the present invention.

[0046] The yarn splicing cart 3 travels to the immediate front of a spinning unit 2 when the yarn Y is cut in that unit 2, and performs yarn splicing. The yarn splicing cart 3 has a yarn splicing device 31, a suction nozzle 32, and a suction mouth 33. The yarn splicing device 31 splices the guided yarn Y together. The yarn splicing device 31 is, for example, a splicer that splices the yarn Y using compressed air or a knotter that mechanically splices the yarn Y. The suction nozzle 32 captures the yarn Y on the air spinning device 7 side and guides it to the yarn splicing device 31. The suction mouth 33 captures the yarn Y on the winding unit 13 side and guides it to the yarn splicing device 31.

[0047] Here, the unit controller 10 described above has a control board 52, which will be described later. The control board 52 has multiple motor drivers and other electronic devices for controlling the operation of each motor. The unit controller 10 also has solenoid valves 43 and 44, which are described above. The control board 52 controls the solenoid valves 43 and 44. The supply state of compressed air to each part is adjusted by the corresponding solenoid valves. A hose (described later) through which compressed air flows is connected to the solenoid valves. Here, for example, if a malfunction occurs during the operation of the spinning unit 2, such as the hose of the solenoid valve 43 coming loose, depending on the arrangement of the control board 52, compressed air may be unintentionally sprayed onto the control board 52 via the hose. This may cause adverse effects on the control board 52. Therefore, in order to suppress adverse effects on the control board 52 by compressed air, the unit controller 10 is configured as follows.

[0048] (Unit Controller) Details of the unit controller 10 will be explained with reference to Figures 4(a) to 4(b). Figures 4(a) and 4(b) are front views of the unit controller 10. Figure 5(a) is a view taken along arrow V(a) in Figure 4(a). Figure 5(b) is a view taken along arrow V(b) in Figure 4(b). In other words, Figures 5(a) and 5(b) are side views of the unit controller 10. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 4(b). In other words, Figure 6 is a side cross-sectional view of the housing 54 and its vicinity, which will be described later. Figure 7 is a bottom view of the manifold 59, which will be described later.

[0049] As described above, the unit controller 10 is provided in correspondence with the two spinning units 2. As shown in Figures 4(a) to 6, the unit controller 10 has an installation section 51. The installation section 51 is a unit equipped with a control board 52 (see Figure 6) and a plurality of solenoid valves 53 (the adjustment section of the present invention; see Figures 4(a) to 5(b)). The control board 52 is, for example, a general printed circuit board on which various electronic devices are mounted. The plurality of solenoid valves 53 include the solenoid valves 43 and 44 described above. Each solenoid valve 53 is, for example, a known two-port solenoid valve having an inlet 53a and an outlet 53b, but is not limited thereto.

[0050] (Installation part) The configuration of the mounting section 51 will now be described. The mounting section 51 is positioned in the space between the fixing member 42 and the sliver support section 19 in the vertical direction (see Figure 3). The mounting section 51 is configured substantially symmetrically (see Figure 4(a)). The mounting section 51 is attached to the frame member 41. As shown in Figures 4(a) and 4(b), the mounting section 51 includes, for example, a housing 54 (the mounting section body of the present invention), two support plates 55, and two covers 56. In addition, a connecting member 57, two mounting members 58, and two manifolds 59 are attached to the mounting section 51. In Figures 3, 5(a), and 5(b), only one of the two manifolds 59 is shown.

[0051] The housing 54 is a box-shaped member that houses the control board 52. The housing 54 has a roughly rectangular parallelepiped shape with an open top. The housing 54 is formed, for example, by sheet metal processing of a plate-shaped metal member. This promotes the escape of heat generated inside the housing 54 to the housing 54 side by thermal conduction. The housing 54 has, for example, a front wall portion 54f, a rear wall portion 54r, and a bottom portion 54b (see Figures 5(a) to 6). The front wall portion 54f is provided at the front end of the housing 54 and extends in the vertical and horizontal directions. Multiple through holes 61 are formed in the front wall portion 54f that penetrate in the front-rear direction (see Figures 4(a) and 4(b)). Preferably, the multiple through holes 61 are arranged side by side, for example, in the left-right direction. Preferably, a cable (not shown) that electrically connects a motor (not shown) that reciprocates the apron belt 18a in the left-right direction to a power supply passes through a through hole 61 located in the center in the left-right direction. This is because the motor is provided in common for the two spinning units 2, as described above. However, the cable arrangement is not limited to this. The rear wall portion 54r is provided at the rear end of the housing 54 and extends in the vertical and horizontal directions. The rear wall portion 54r is located at the rearmost side of the housing 54 (on the opposite side of the multiple draft roller pairs in the front-rear direction). Multiple through holes 62 are formed in the rear wall portion 54r, penetrating in the front-rear direction. Only one through hole 62 is shown in Figure 6. The bottom portion 54b is provided at the lower end of the housing 54 and extends in the front-rear and horizontal directions. The roughly rectangular parallelepiped space (region) formed by the housing 54 is called the first region R1 (see Figures 5(a) to 6). The components housed in the first region R1 will be described later.

[0052] A lid 60 is provided on the upper side of the housing 54, for example, which can open and close the opening of the housing 54. The lid 60 is configured to be detachable from or movable to the housing 54. In other words, the lid 60 is movable between an operating position and an exposed position. The operating position is the position for moving the sliver S downstream in the direction of movement. The exposed position is the position for exposing the control board 52 to the outside. A sliver support part 20 is fixed to the upper surface of the lid 60. The sliver support part 20 is provided so as to move integrally with the lid 60. When the lid 60 is in the operating position, the sliver support part 20 can stably guide the sliver S. This makes it possible to operate the spinning unit 2 stably. When the lid 60 is in the exposed position, it opens the opening of the housing 54 and exposes the control board 52 to the outside. When the lid 60 is in the exposed position, an operator can perform maintenance on the unit controller 10.

[0053] Each of the two support plates 55 (see Figures 4(a) and 4(b)) is, for example, a roughly rectangular plate member. Each support plate 55 extends in the left-right direction and also extends diagonally downward and forward from the lower and front ends of the housing 54. The two support plates 55 are fixed to the left and right portions of the front end of the housing 54, respectively. The left support plate 55 is also called support plate 55L. The right support plate 55 is also called support plate 55R. Multiple solenoid valves 53, corresponding to one spinning unit 2, are attached to the upper surface of each support plate 55. A notch 55a is formed at the upper end of each support plate 55, through which, for example, multiple upstream hoses 81 (described later) can pass (see Figures 5(a) and 5(b)). Note that in Figures 4(a) and 4(b), four solenoid valves 53 are shown corresponding to one spinning unit 2. The solenoid valves 53 other than solenoid valves 43 and 44 are connected to, for example, the first cleaning unit and the second cleaning unit described above (not shown). However, the number of solenoid valves 53 is not limited to these.

[0054] Each of the two covers 56 (see Figures 4(a) and 4(b)) is a decorative cover that covers the space near the front portion of the housing 54. The two covers 56 are arranged side by side in the left-right direction. The left cover 56 is called cover 56L. The right cover 56 is called cover 56R. Covers 56L and 56R are configured to be approximately symmetrical to each other in the left-right direction. To avoid repetition of explanations, only the structure of cover 56R will be described below, and the structure of cover 56L will be omitted. Cover 56R is configured to be able to open and close the right-right portion of the opening of the housing 54. Cover 56R is pivotably attached to the lid 60 via a pivot shaft 63 (see Figures 5(a) and 5(b)) that extends along the left-right direction. The state in which cover 56R closes the right-right portion of the opening is called the closed state (see Figures 4(a) and 5(a)). The state in which the right side of the opening of the cover 56R is open is called the open state (see Figures 4(b) and 5(b)). The position of the cover 56R when it is closed is called the operating position. The position of the cover 56R when it is open is called the exposure position.

[0055] Examples of components of cover 56R will be described. In the description of these components, it will be assumed that cover 56R is in a closed state. Cover 56R has an upper plate portion 64, a front plate portion 65, and a side plate portion 66. The upper plate portion 64 is, for example, a roughly rectangular plate-shaped portion. The upper plate portion 64 is positioned at the upper end of cover 56R. The upper plate portion 64 rests on the upper end of housing 54 and closes the right side portion of the opening of housing 54. The left end surface (not shown in the reference numerals) of the upper plate portion 64 is positioned to be in contact with, for example, the right end surface (not shown in the reference numerals) of cover 56L. For example, the sliver support portion 19 described above is fixed to the right end of the upper plate portion 64. As a result, the sliver support portion 19 moves integrally with cover 56R. The right end of the upper plate portion 64 is connected to the side plate portion 66. The front plate portion 65 is, for example, a roughly rectangular plate-shaped portion. The upper end of the front plate portion 65 is connected to the front end of the upper plate portion 64. The right end of the front plate portion 65 is connected to the side plate portion 66. The front plate portion 65 extends in the left-right direction and also extends diagonally downward and forward from the front end of the upper plate portion 64. When viewed from the front-rear direction, the front plate portion 65 is configured to cover, for example, the right side portion of the housing 54 (see Figure 4(a)). The side plate portion 66 is, for example, a roughly pentagonal plate-shaped portion (see Figures 5(a) and 5(b)). The side plate portion 66 is located at the right end of the cover 56R. The side plate portion 66 is connected to the right end of the upper plate portion 64 and the right end of the front plate portion 65. When viewed from the left-right direction, the side plate portion 66 is preferably configured to cover a plurality of solenoid valves 53 attached to the support plate 55R (see Figure 5(a)). For example, the upper end of the rear end of the side plate portion 66 is attached to the right side of the housing 54 via a pivot shaft 63.

[0056] When the cover 56R is in the operating position, it closes the right-hand portion of the opening of the housing 54 as described above (see Figures 4(a) and 5(a)). When the cover 56R is in the operating position, the sliver support 19 can stably guide the sliver S. This makes it possible to stably operate the spinning unit 2. The space (region) outside the housing 54, surrounded by the closed cover 56R and support plate 55R, is called the second region R2 (see Figure 5(a)). The second region R2 is the region in which a plurality of solenoid valves 53 attached to the support plate 55R are housed. The first region R1 and the second region R2 are separated (partitioned) by the front wall 54f and bottom 54b of the housing 54. The front wall 54f and bottom 54b correspond to the partition portion of the present invention.

[0057] When the cover 56R is in the exposed position, it opens the right-hand portion (more precisely, the front portion of the right-hand side) of the opening in the housing 54, exposing the control board 52 to the outside (see Figures 4(b) and 5(b)). The exposed position is, for example, above the operating position. When the cover 56R is in the exposed position, an operator can perform maintenance on the right-hand portion of the unit controller 10.

[0058] The connecting member 57 (see Figures 4(a) and 4(b)) is a member that connects and stabilizes the two support plates 55. The connecting member 57 may be made of, for example, sheet metal. The connecting member 57 may have a substantially U-shape with an open top when viewed from the front or back. The material and shape of the connecting member 57 are not limited to these. The two mounting members 58 are members for attaching the installation section 51 to the frame member 41 (see Figure 3). The two manifolds 59 are provided corresponding to the two spinning units 2. Each manifold 59 is a member that distributes compressed air supplied from the compressed air source 5b to multiple passages (more details will be described later).

[0059] (Member placed in the first region) Various components arranged in the internal space of the housing 54 (i.e., the first region R1) will be described with reference to Figure 6. As shown in Figure 6, the first region R1 houses, for example, a control board 52, a cover 71, and a heat sink 72.

[0060] The control board 52 is a printed circuit board on which, for example, multiple electronic devices are mounted and wiring is formed. The thickness direction of the control board 52 is, for example, approximately parallel to the vertical direction, but is not limited to this. The multiple electronic devices include, for example, a motor driver 73. The motor driver 73 is an electronic device that drives and controls a motor 77, which is one of the multiple motors described above provided in the spinning unit 2. The motor driver 73 is fixed, for example, to the lower surface of the control board 52. The motor driver 73 is a device for supplying current to the motor and is prone to generating heat with large currents. The motor driver 73 corresponds to the heat-generating element of the present invention. For example, a cable 74 is connected to the rear end of the control board 52. For example, a cable 75 is connected to the front end of the control board 52. Cable 74 electrically connects the control board 52 to a power supply 76 that supplies power to the motor driver 73. The power supply 76 is located, for example, behind the control board 52. Cable 74 extends from the control board 52 to the rear, passing through the rear wall portion 54r (the rear side of the present invention). In other words, the control board 52 is electrically connected to the power supply 76 via the rear side of the installation portion 51, which is located on the opposite side from the multiple draft roller pairs. Cable 75 electrically connects the motor 77 to the control board 52. The motor 77 is located, for example, in front of the control board 52. Cable 75 extends from the control board 52 to the front, passing through the front wall portion 54f (the front side of the present invention). In other words, the control board 52 is electrically connected to the motor 77 via the front side of the installation portion 51, which is located on the side of the multiple draft roller pairs. The motor 77 is, for example, a motor that rotates one of the multiple draft roller pairs. The motor 77 corresponds to the drive unit of the present invention. Multiple motors, including the motor 77, which each rotates multiple draft roller pairs, correspond to multiple drive units of the present invention.

[0061] The cover 71 is for protecting the upper surface of the control board 52. The cover 71 is provided to cover the control board 52 from above. Multiple slits 78 are formed in the cover 71. Because the surface area of ​​the cover 71 is increased by the multiple slits 78, heat dissipation to the space outside the cover 71 is promoted. The names of the devices etc. provided on the control board 52 may be inscribed on the outer surface of the cover 71.

[0062] The heat sink 72 is a component that dissipates heat generated by the control board 52 to the housing 54. The heat sink 72 is, for example, a generally rectangular and flat metal component. The heat sink 72 extends, for example, in the front-to-back direction and also in the left-to-right direction. The heat sink 72 is provided between the control board 52 and the bottom 54b of the housing 54 in the thickness direction of the control board 52. The heat sink 72 has a protrusion 72a that projects upward (towards the control board 52). The protrusion 72a is positioned in approximately the same location as the motor driver 73 in the front-to-back and left-to-right directions. That is, the protrusion 72a is located directly below the motor driver 73. In other words, the protrusion 72a at least partially overlaps the motor driver 73 when viewed from the thickness direction. More precisely, it is preferable that a protective sheet (not shown) protecting the motor driver 73 is provided between the motor driver 73 and the heat sink 72 in the thickness direction of the control board 52. Alternatively, the motor driver 73 may be in contact with the heat sink 72. The heat generated by the motor driver 73 is dissipated through the upper surface of the protrusion 72a, through the inside of the heat sink 72, and to the bottom 54b of the housing 54. It is preferable that the shape of the heat sink 72 differs from that of its front end and rear end, for example. In this case, it is possible to prevent the worker from attaching the heat sink 72 to the housing 54 in the wrong orientation.

[0063] (Member placed in the second region) Various components arranged in the second region R2 will be described with reference to Figures 4(a) to 5(b). As mentioned above, the second region R2 is provided with, for example, a plurality of solenoid valves 53 (see Figures 4(a) and 4(b)). An upstream hose 81 and a downstream hose 82 are connected to each of the plurality of solenoid valves 53 (see Figures 5(a) and 5(b)). In addition, in the supply direction in which compressed air is supplied, the manifold 59 described above is provided upstream of the plurality of upstream hoses 81 (see Figures 5(a) and 5(b)). Furthermore, in the supply direction, a common hose 83 is provided between the compressed air source 5b (see Figure 1) and the manifold 59. For example, a duct (not shown) is provided that extends long from the compressed air source 5b in the left-right direction toward the plurality of spinning units 2. The common hose 83 is connected to, for example, this duct.

[0064] Multiple upstream hoses 81 (see Figure 7) and multiple downstream hoses 82 (see Figure 4(b)) are provided, each corresponding to one of the multiple solenoid valves 53. In the supply direction, the downstream end of each of the multiple upstream hoses 81 is attached to the inlet 53a of the corresponding solenoid valve 53. In the supply direction, the upstream end of each of the multiple downstream hoses 82 is attached to the outlet 53b of the corresponding solenoid valve 53. The downstream hoses 82 extend forward of the installation section 51 (i.e., across multiple pairs of draft rollers in the front-rear direction). The downstream hoses 82 correspond to the second piping of the present invention. The connection position between the solenoid valve 53 and the downstream hose 82 (i.e., the position of the outlet 53b) is lower than the connection position between the solenoid valve 53 and the upstream hose 81 (i.e., the position of the inlet 53a). The pneumatic spinning machine 7 is located below the corresponding solenoid valve 53 (solenoid valve 43). Furthermore, the suction device 26 is located below the corresponding solenoid valve 53 (solenoid valve 44). A virtual line segment connecting the inlet 53a and outlet 53b of the solenoid valve 53 (more precisely, a virtual line segment connecting the center of the inlet 53a and the center of the outlet 53b) is defined as the virtual line segment VLS (see Figure 5(b)). The angle of inclination of the virtual line segment VLS in the direction of extension with respect to the direction of alignment of the multiple draft roller pairs (i.e., the angle between the direction of extension and the direction of alignment) is preferably 0 degrees or more and 30 degrees or less. The angle of inclination is even more preferably 0 degrees or more and 15 degrees or less.

[0065] Each of the multiple downstream hoses 82 is configured to be detachably attached to the corresponding solenoid valve 53. Preferably, each of the multiple downstream hoses 82 extends along the direction of alignment (see Figure 3). Furthermore, preferably, the multiple downstream hoses 82 are configured to be distinguishable from each other by appearance, for example, by having different colors. This prevents workers from mistakenly connecting the downstream hoses 82 to the solenoid valve 53 during assembly or maintenance of the spinning unit 2.

[0066] The manifold 59 is a component that distributes compressed air supplied via a common hose 83 to a plurality of upstream hoses 81. The manifold 59 has a body 91, an inlet 93, and a plurality of outlets 94. The body 91 is, for example, a generally cylindrical component. The body 91 extends, for example, in the front-to-back direction. The body 91 is, for example, a resin component. The body 91 may be formed by assembling a plurality of parts. Depending on the required strength and dimensional accuracy of the parts, the materials, etc., may differ among the plurality of parts. Inside the body 91, a common flow path 91a and a plurality of individual flow paths 91b (distribution section of the present invention) are formed.

[0067] Within the manifold 59, the supply direction refers to the direction in which the multiple individual flow paths 91b are aligned (in this embodiment, the front-to-back direction). That is, within the manifold 59, the rear side is defined as the upstream side in the supply direction, and the front side is defined as the downstream side in the supply direction. The common flow path 91a extends from the uppermost part of the manifold 59 to the downstream side in the supply direction. A filter 92 is provided near the upstream end of the common flow path 91a in the supply direction. The filter 92 is a component that removes foreign matter that unintentionally flows in from the compressed air source 5b side through the common hose 83. The filter 92 is provided upstream (rear side) of the multiple individual flow paths 91b of the manifold 59 in the supply direction. An inlet 93 is provided upstream of the common flow path 91a in the supply direction (for example, at the rear end of the main body 91). The common hose 83 is connected to the inlet 93. The common hose 83 extends rearward from the housing 54. In other words, the common hose 83 extends in the front-rear direction, on the side opposite to the multiple draft roller pairs, separated by the installation section 51. The common hose 83 corresponds to the first piping of the present invention.

[0068] Multiple individual channels 91b are channels that branch off from the common channel 91a midway. Multiple individual channels 91b are arranged side by side, for example, in the front-to-back direction. Multiple individual channels 91b are provided corresponding to multiple upstream hoses 81. However, this is not limited to this, and other individual channels (not shown) connected to piping other than the upstream hoses 81 may be provided. Multiple outlets 94 are provided on the downstream side of each of the multiple individual channels 91b in the supply direction (for example, on the side of the main body 91). Each of the multiple outlets 94 is connected to a corresponding upstream hose 81.

[0069] Multiple injection units are connected to the manifold 59. These injection units include the spinning nozzles 7a of the air spinning machine 7. One of the multiple solenoid valves 53 (solenoid valve 43) adjusts the supply of compressed air to the spinning nozzles 7a. The remaining multiple solenoid valves 53 (e.g., solenoid valve 44) are each connected to one or more devices used intermittently (e.g., intake units 7b). Although not shown in the diagram, the air cylinder 26c (see Figure 2) described above may also be connected to the manifold 59 via solenoid valve 45 (see Figure 2).

[0070] Some of the multiple outlets 94 (not shown here) may have, for example, a 3-port solenoid valve (not shown) integrally formed thereon. The 3-port solenoid valve may adjust the supply state of compressed air to an air cylinder (not shown) that drives the suction port 26a of the suction device 26, for example. The 3-port solenoid valve is preferably located on the downstream side in the supply direction of the common flow path 91a.

[0071] As described above, the installation section 51 has a partition section (front wall section 54f and bottom section 54b) that separates the first region R1 and the second region R2. This prevents compressed air from being accidentally blown onto the control board 52 when a malfunction occurs in the solenoid valve 53. Therefore, the adverse effects of compressed air on the control board 52 can be suppressed in the spinning unit 2.

[0072] Furthermore, the heat sink 72 has a protrusion 72a. This allows heat from the motor driver 73 to be dissipated to the heat sink 72 via the protrusion 72a, and prevents the heat sink 72 from transferring heat to other electronic devices. Therefore, it is possible to suppress the unintentional overheating of electronic devices.

[0073] Furthermore, the mounting section 51 is attached to the frame member 41. This allows the control board 52 to be placed near the multiple motors that are to be controlled. Consequently, the wiring from the control board 52 to the controlled objects can be shortened.

[0074] Furthermore, the mounting section 51 is positioned in the space between the sliver support section 19 and the fixing member 42 in the vertical direction. This space can be used to position the mounting section 51. Therefore, compared to a configuration where the mounting section 51 is positioned in another location, space savings can be achieved.

[0075] Furthermore, the sliver support section 20 is provided to move integrally with the lid 60. Moving the lid 60 to the exposed position makes it easier for the operator to access the housing 54. Therefore, maintenance near the housing 54 can be easily performed when the lid 60 is in the exposed position. When the sliver support section 20 is in a position different from the operating position, it is difficult to support the sliver S in the same way as during normal operation. For this reason, the spinning unit 2 is not normally operated when the lid 60 is in the exposed position. This prevents the control board 52 from operating when the lid 60 is in the exposed position. Therefore, the possibility of an operator accidentally touching the control board 52 while it is operating is reduced, and the safety of the spinning unit 2 can be improved.

[0076] Furthermore, since the cable (wiring) extends from the rear wall 54r (back) to the front wall (front) of the installation section 51, the layout near the installation section 51 can be simplified.

[0077] Furthermore, the downstream hose 82 and the common hose 83 extend to opposite sides of the installation section 51. Therefore, the layout near the installation section 51 can be simplified.

[0078] Furthermore, the downstream hose 82 extends in a direction that takes into account the positional relationship between the solenoid valve 53 and the injection unit. Therefore, bending of the downstream hose 82 can be suppressed.

[0079] Furthermore, the inclination angle of the imaginary line segment VLS connecting the inlet 53a and outlet 53b of the solenoid valve 53 with respect to the alignment direction is between 0 and 30 degrees. The injection section is located below the solenoid valve 53. Therefore, the layout near the installation section 51 can be simplified.

[0080] Furthermore, the downstream hose 82 extends along the direction of alignment. The injection section is located below the solenoid valve 53. Therefore, the layout near the installation section 51 can be simplified.

[0081] Furthermore, in the supply direction, the filter 92 is provided upstream of the multiple individual flow paths 91b of the manifold 59. This effectively prevents foreign matter from entering the multiple solenoid valves 53 via the manifold 59.

[0082] Furthermore, the solenoid valve 53 that adjusts the supply state of compressed air to the air spinning machine 7 is used during normal spinning, while the remaining solenoid valves 53 are used intermittently (i.e., only temporarily). Therefore, even when compressed air is distributed by the manifold 59, disturbances in the supply state of compressed air to the air spinning machine 7 can be suppressed.

[0083] Next, modified examples of the above embodiments will be described. However, components having the same configuration as the above embodiments will be denoted by the same reference numerals and their descriptions will be omitted as appropriate.

[0084] (1) In the above embodiment, the first region R1 is the space inside the housing 54, and the second region R2 is a part of the space outside the housing 54. However, it is not limited to this. For example, the first region R1 and the second region R2 may be formed inside the same housing (not shown). The first region R1 and the second region R2 may be formed by a partition member (not shown) that divides the internal space of the housing.

[0085] (2) In the embodiments described above, the heat sink 72 was provided with a protrusion 72a. However, it is not limited to this. The heat sink 72 may be, for example, substantially flat overall. Alternatively, the heat sink 72 may not be provided at all. In this case, the heat from the heat-generating part may be dissipated by means other than the heat sink 72. Alternatively, the electronic device including the heat-generating part may have sufficient resistance to heat.

[0086] (3) In the embodiments described above, the mounting portion 51 was assumed to be attached to the frame member 41. However, it is not limited to this. The mounting portion 51 may be directly fixed to, for example, the fixing member 42.

[0087] (4) In the embodiments described above, the mounting portion 51 was positioned in the space between the sliver support portion 19 and the fixing member 42 in the vertical direction. However, it is not limited to this. The mounting portion 51 may be positioned in a different location.

[0088] (5) In the embodiments described above, the sliver support portion 20 is assumed to move integrally with the lid 60. However, it is not limited to this. The sliver support portion 20 may be movable independently of the lid 60, for example. Alternatively, the sliver support portion 20 may be fixed to the housing 54, for example. Also, the sliver support portion 19 may be movable independently of the cover 56, for example, or it may be fixed to the housing 54, for example.

[0089] (6) The arrangement of the upstream hose 81, downstream hose 82, common hose 83, cable 74 and cable 75 is not limited to those described above.

[0090] (7) The positional relationship between the connection position of the solenoid valve 53 and the downstream hose 82 and the injection unit is not limited to those described above. For example, the connection position may be approximately the same as the position of the injection unit in the vertical direction. Alternatively, the connection position may be lower than the injection unit.

[0091] (8) In the embodiments described above, the angle of inclination of the virtual line segment VLS in the direction of extension with respect to the direction of alignment was assumed to be 0 degrees or more and 30 degrees or less. However, it is not limited to this. The angle of inclination may be greater than 30 degrees.

[0092] (9) In the embodiments described above, the downstream hose 82 was assumed to extend along the direction of alignment. However, it is not limited to this. The downstream hose 82 may extend with an inclination with respect to the direction of alignment.

[0093] (10) In the embodiments described above, the filter 92 is provided near the upstream end of the common flow path 91a in the supply direction. However, it is not limited to this. For example, multiple filters (not shown) may be provided corresponding to multiple individual flow paths 91b. Alternatively, the filters may be provided further upstream than the manifold 59 in the supply direction.

[0094] (11) In the embodiments described above, the solenoid valve 53 corresponding to the injection unit other than the spinning nozzle 7a was used intermittently. However, it is not limited to this. The solenoid valve 53 corresponding to the injection unit other than the spinning nozzle 7a may be used continuously. However, in this case, it is preferable that measures be taken to stabilize the supply of compressed air to the spinning nozzle 7a.

[0095] (12) The manifold 59 is not required. In other words, each solenoid valve 53 and the compressed air source 5b may be connected without going through the manifold 59. For example, each upstream hose 81 may be connected to the duct described above.

[0096] (13) In the embodiments described above, the winding section 13 was positioned at the lowest part of the spinning unit 2 (i.e., below the multiple draft roller pairs). However, it is not limited to this. The winding section 13 may be positioned above the multiple draft roller pairs, for example.

[0097] (14) In the embodiments described above, one unit controller 10 is provided corresponding to two spinning units 2. However, it is not limited to this. The number of spinning units 2 corresponding to one unit controller 10 may be one, or it may be three or more.

[0098] (15) The present invention may also be applied to winding devices other than the spinning unit 2. [Explanation of symbols]
