Description

[Technical Field]

[0001] The present invention relates to a spinning machine having a pipe for supplying air to a spinning unit. [Background technology]

[0002] The spinning machine of Patent Document 1 includes a plurality of spinning units and a storage section disposed at one end of the spinning units in the parallel arrangement direction. The storage section is provided with an air supply section that supplies air to the spinning units and the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-67882 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, the storage section is divided into upper and lower sections, and the air supply section is located in the lower section. Therefore, in Patent Document 1, the piping route in the internal space of the storage section becomes long, which may result in the internal space of the storage section not being used appropriately.

[0005] The present invention has been made in view of the above circumstances, and its main object is to provide a spinning machine configured such that components are efficiently and rationally arranged inside a housing in which members for supplying air to the spinning units are arranged.

[0006] The problem to be solved by the present invention is as described above. Next, the means for solving this problem and the effects thereof will be explained.

[0007] According to an aspect of the present invention, there is provided a spinning machine having the following configuration. That is, the spinning machine includes a plurality of spinning units, an air pipe, a housing, an air filter, a regulator, and a display device. The spinning units are arranged in a parallel line and produce yarn by spinning. The air pipe supplies air to the plurality of spinning units. The housing is arranged adjacent to the spinning units, has a first surface, and has an interior area formed therein. The air filter is arranged in the interior area along the first surface and purifies the air supplied to the spinning units. The regulator is arranged in the interior area along the first surface and adjusts the pressure of the air supplied to the spinning units. The display device is arranged on the housing along the air pipe and displays information related to spinning. The interior area of ​​the housing has a lower area and an upper area. The lower region is provided with at least one of a storage space for a traveling carriage that travels between the plurality of spinning units in the parallel direction and a storage space for a storage container that stores additives to be supplied to the spinning units. The upper region is located higher than the lower region and is equipped with the air filter and the regulator. The air piping includes a spinning piping and an inlet piping. The spinning piping is disposed in a space where the plurality of spinning units are located and supplies air to each of the spinning units. The inlet piping is provided with the air filter and the regulator, and the inlet piping directly supplies air that has passed through the air filter and the regulator to the spinning piping. The height of the connection point between the inlet piping and the spinning piping is referred to as a reference height, and the inlet piping is disposed in the upper region at a height equal to or higher than the reference height.

[0008] Because the inlet pipe is in the upper region and above the reference height, the pipe can be shortened. As a result, the space for the pipe can be reduced, and pressure loss can be reduced. Furthermore, by arranging the inlet pipe in the upper region, the lower region can be made wider, thereby creating the above-mentioned storage space. In addition, by providing a display device along the air pipe, the space inside the housing can be used effectively. As a result, parts can be arranged efficiently and rationally inside the housing.

[0009] In the spinning machine, the first surface is preferably a surface at an end of the housing in the parallel direction and on the opposite side to the side on which the spinning pipe is located.

[0010] This prevents the spinning piping and spinning unit from getting in the way when performing maintenance on the air filter or regulator, etc. Also, keys for operator operation may be located on another side of the housing, and by avoiding that side, the placement of the keys is not obstructed.

[0011] In the spinning machine, it is preferable that the housing has a door at a position corresponding to the first surface that switches between an open state in which the internal area is accessible and a closed state in which the internal area is not accessible.

[0012] This allows for easy maintenance since the air filter or regulator can be accessed simply by opening the door.

[0013] The spinning machine preferably has the following configuration: the spinning pipe is an additive spinning pipe that supplies air to which the additive has been added, and the additive-added air is supplied from an additive introduction pipe to the additive spinning pipe.

[0014] This allows the air containing the additive to be provided to the spinning unit.

[0015] The spinning machine preferably has the following configuration: the air pipe has a branch pipe branching from the inlet pipe in the internal region of the housing, the additive is supplied from the storage container to the branch pipe, and the branch pipe is connected to the additive inlet pipe.

[0016] As a result, the connection point between the inlet pipe and the branch pipe is not located outside the housing, so the space required outside the housing can be reduced.

[0017] The spinning machine is preferably configured as follows: The spinning machine includes an addition operation unit that allows an operator to adjust the amount of additive supplied. The addition operation unit is disposed on an end surface of the housing that is perpendicular to the parallel direction in a plan view and on the surface on which the display device is disposed.

[0018] This allows the addition operation unit to be located at a position that is easily accessible to the operator, making it easy to make adjustments regarding the supply of additives.

[0019] The spinning machine preferably has the following configuration: the spinning machine includes a spinning pressure meter that displays the detection result of the air pressure related to spinning in the spinning unit, and the spinning pressure meter is disposed on the surface of the housing where the addition operation unit is disposed.

[0020] This allows the operator to operate the addition operation section while watching the spinning pressure gauge.

[0021] The spinning machine preferably has the following configuration: the storage container has an opening, a closing portion, and a marker. The closing portion closes the opening. The marker is positioned so as to be hidden by the closing portion when the opening is closed, when viewed in a predetermined direction.

[0022] This makes it easy to determine whether the cap is properly attached based on whether the mark is visible.

[0023] The spinning machine is preferably configured as follows: The spinning machine includes a protrusion attached to the storage container, and the protrusion protrudes when the pressure inside the storage container reaches or exceeds a threshold value.

[0024] This makes it possible to easily detect the occurrence of a pressure abnormality. [Brief explanation of the drawings]

[0026] Next, a spinning machine 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0027] The spinning machine 1 of this embodiment includes a plurality of spinning units 2 arranged side by side, a yarn splicing carriage (traveling carriage) 3, and a component storage box (housing) 20. Hereinafter, the direction in which the spinning units 2 are lined up will be referred to as a first direction (or parallel direction).

[0028] Each spinning unit 2 includes, in order from upstream to downstream, a fiber bundle guide 4, a draft device 5, an air spinning device 6, a yarn monitoring device 7, a yarn storage device 8, and a winding device 10.

[0029] The fiber bundle guide 4 guides the fiber bundle 14 supplied from a sliver case (not shown). The fiber bundle 14 guided by the fiber bundle guide 4 is supplied to a draft device 5.

[0030] The draft device 5 includes a plurality of pairs of rollers arranged opposite to each other. The fiber bundle 14 is sandwiched between the opposing rollers, and the rollers are rotated to stretch (draft) the fiber bundle 14.

[0031] The air spinning device 6 spins the fiber bundle 14 delivered by the draft device 5 to produce yarn 15. The air spinning device 6 injects compressed air to generate a swirling airflow, thereby twisting the fiber bundle 14 and producing yarn 15.

[0032] The yarn monitoring device 7 monitors the thickness of the traveling yarn 15 using an optical sensor (not shown). Based on the detection results of the yarn monitoring device 7, it is possible to detect yarn defects in the yarn 15 (for example, locations where there is an abnormality in the thickness of the yarn 15). When a yarn defect is detected, the spinning machine 1 cuts the yarn 15 and performs yarn splicing using the yarn splicing cart 3, which will be described later.

[0033] The yarn pooling device 8 includes a yarn pooling roller. The yarn pooling device 8 winds the yarn 15 around the outer peripheral surface of the yarn pooling roller to temporarily pool the yarn 15. The yarn pooling device 8 functions as a kind of buffer for the yarn 15. This eliminates problems (such as slack in the yarn 15) caused by a mismatch between the spinning speed in the air spinning device 6 and the winding speed (the running speed of the yarn 15 wound onto the package 18) for some reason.

[0034] The winding device 10 winds a yarn 15 onto a bobbin 17 to form a package 18. The winding device 10 includes a winding drum and a traverse device. The winding drum contacts the bobbin 17 (or the package 18) and rotates integrally with the bobbin 17. The traverse device traverses the yarn 15 being wound onto the bobbin 17.

[0035] In the spinning machine 1 of this embodiment, a drive device that drives the winding drum and a drive device that drives the traverse device are provided for each spinning unit 2. Therefore, it is possible to switch between operating and not operating the traverse device and between operating and not operating the winding drum for each spinning unit 2. Alternatively, the drive device that drives the winding drum and the drive device that drives the traverse device may be common to multiple spinning units 2.

[0036] The yarn splicing cart 3 is equipped with a motor and wheels (not shown), and travels in the parallel direction of the spinning units 2. The yarn splicing cart 3 travels to a spinning unit 2 that requires yarn splicing, and performs the yarn splicing for that spinning unit 2. The yarn splicing cart 3 is equipped with a suction pipe 31, a suction mouth 32, and a yarn splicing device 33.

[0037] The suction pipe 31 and the suction mouth 32 are connected to a negative pressure source and can suck and capture the yarn 15. The suction pipe 31 is movable to approach the air spinning device 6 and captures the yarn 15 fed from the air spinning device 6. The suction mouth 32 is movable to approach the winding device 10 and captures the yarn end wound onto the package 18. The suction pipe 31 and the suction mouth 32 each guide the captured yarn to the yarn joining device 33.

[0038] The yarn splicing device 33 splices the yarn 15 on the air spinning device 6 side with the yarn 15 on the package 18 side. More specifically, the yarn splicing device 33 is an air splicer that untwists the two guided yarns 15 with a swirling air flow, and also combines the two yarns 15 and twists them with the swirling air flow. In this way, the yarn splicing device 33 splices the two yarns 15. The yarn splicing device 33 is not limited to a splicer device and may be, for example, a mechanical knotter.

[0039] Instead of or in addition to the yarn splicing carriage 3, the spinning machine 1 may be provided with a traveling carriage that performs a process other than yarn splicing (for example, collection of the package 18).

[0040] The component storage box 20 is arranged adjacent to the spinning unit 2 located at one end in the first direction. However, the component storage box 20 may also be arranged between the spinning units 2 in the first direction. The component storage box 20 stores various components that make up the spinning machine 1. In the following description, the direction perpendicular to the first direction in a plan view is referred to as the second direction.

[0041] First, the structure of the component housing box 20 will be described with reference to Figure 2. The component housing box 20 has a rectangular parallelepiped outer shape. In this specification, the term "rectangular parallelepiped" does not necessarily mean a strict rectangular parallelepiped shape, but also includes shapes that evoke a rectangular parallelepiped. For example, each face does not necessarily have to be flat; the face may be inclined or curved, or may include portions where no plate material corresponding to the face is disposed.

[0042] As shown in FIG. 2 , three of the four side surfaces of the component housing box 20 are designated as the “first side surface,” the “second side surface,” and the “front surface.” The first side surface is the surface of the four side surfaces of the component housing box 20 that is perpendicular to the first direction and is located opposite the spinning unit 2 (the surface facing the outside). The first side surface corresponds to the “first surface.” The second side surface is the surface of the four side surfaces of the component housing box 20 that is perpendicular to the first direction and is located closer to the spinning unit 2 (the surface facing the spinning unit 2). Note that, when the component housing box 20 is disposed between the spinning units 2 in the first direction, any one surface perpendicular to the first direction may be designated as the first side surface, and the other surface may be designated as the second side surface. The front surface is the surface of the four side surfaces of the component housing box 20 that is perpendicular to the second direction and is located in front of the spinning machine 1. The front side is, for example, the side where there is an aisle for the operator to move around, or the side where the parts that the operator operates or sees are concentrated.

[0043] An inner area for accommodating components is formed inside the component housing box 20. The inner area 21 can be divided into an upper area 22 and a lower area 23. The method for dividing the upper area 22 and the lower area 23 and the components to be placed in each area will be described later.

[0044] The component housing box 20 includes a frame 40. The frame 40 includes frame members (e.g., rod-shaped members) arranged three-dimensionally. Plate-shaped members (doors or panels) are attached to the frame 40. A side door 41 and a side panel 42 are attached to a first side surface.

[0045] The side door 41 is attached to a portion of the first side surface that corresponds to the upper region 22. The side door 41 can be opened and closed by rotating it around a hinge. That is, the side door 41 can be switched between an open state in which the upper region 22 is accessible and a closed state in which the upper region 22 is not accessible.

[0046] The side panel 42 is attached to a portion of the first side surface that corresponds to the lower region 23. Therefore, the side panel 42 is attached at a lower position than the side door 41. The side panel 42 is detachably attached to the frame 40 using fasteners such as bolts. The side panel 42 can be switched between an open state in which the lower region 23 is accessible, and a closed state in which the lower region 23 is inaccessible. However, because the side panel 42 requires bolts to be attached and detached, the effort required to switch between these states is greater than that required for the side door 41.

[0047] A unit-side panel 43 is attached to the second side surface of the component housing box 20. It is not intended that the unit-side panel 43 be detachable (it is either impossible to detach or it would be extremely time-consuming to detach it). The unit-side panel 43 is also formed with a notch 43a as shown in Fig. 3. The notch 43a has a shape and size that allows the yarn splicing cart 3 to pass through.

[0048] A front panel 44 and a front door 45 are attached to the front of the component housing box 20.

[0049] The front panel 44 is attached to a portion of the front surface corresponding to the upper region 22. The front panel 44 is not intended to be detachable (it is either not detachable or requires a great deal of effort to detach). A hole 44a is formed in the front panel 44. The hole 44a is a hole for exposing a display device and a control operation unit, which will be described later.

[0050] The front door 45 is attached to a portion of the front surface that corresponds to the lower area 23. Therefore, the front door 45 is attached at a position lower than the front panel 44. The front door 45 can be opened and closed by rotating it around a hinge. That is, the front door 45 can be switched between an open state in which the lower area 23 is accessible, and a closed state in which the lower area 23 is not accessible.

[0051] The above-described door and panel are merely examples. For example, a single panel or door may be provided that covers the entire first side (or front). A panel may be provided instead of the door, or the door and panel may be omitted.

[0052] Next, the components housed in the component housing box 20 will be described with reference to Figures 2 to 7. The component housing box 20 is divided into three parts: the air piping 50, the components of the air processing system, and the components that are operated or visually recognized by the operator. These will be described in order below.

[0053] First, the air piping 50 will be described. The air piping 50 is a collective term for multiple pipes for supplying air to the spinning unit 2 (particularly the air spinning device 6). As shown in FIG. 5, the air piping 50 includes facility piping 51. The facility piping 51 is a pipe on the facility side of a factory or the like where the spinning machine 1 is installed, or a pipe connected to a pipe on the facility side. A blower for blowing air is provided upstream of the facility piping 51.

[0054] The air supplied from the air piping 50 passes through either a first supply path that supplies the air to the spinning unit 2 without containing any additives, or a second supply path that supplies the air containing additives to the spinning unit 2. The spinning machine 1 of this embodiment is provided with both the first supply path and the second supply path, but either one may be omitted.

[0055] The first supply path includes a first inlet pipe (inlet pipe) 52 and a first spinning pipe (spinning pipe) 53. The first inlet pipe 52 is located downstream of the facility pipe 51, and air flowing through the facility pipe 51 further flows through the first inlet pipe 52. The first inlet pipe 52 is a pipe disposed within the component housing box 20. The first spinning pipe 53 is connected to the downstream end of the first inlet pipe 52 and passes through an area where multiple spinning units 2 are disposed. The first spinning pipe 53 branches according to the positions of the multiple spinning units 2 and supplies air to each spinning unit 2. In this embodiment, the downstream end of the first inlet pipe 52 is connected to the first spinning pipe 53, so the first inlet pipe 52 supplies air directly (without adding any additives) to the first spinning pipe 53. "Directly" means not passing through another pipe for transporting air. However, even if a member for connecting the first inlet pipe 52 and the first spinning pipe 53 is used, this also falls under the category of "directly."

[0056] The second supply path includes a branch pipe 55, a second inlet pipe (additive inlet pipe) 56, and a second spinning pipe (spinning pipe, additive spinning pipe) 57. The branch pipe 55 is a pipe branching off from the facility pipe 51 or the first inlet pipe 52. The branch pipe 55 is a pipe for supplying additives, and the additives are supplied from a storage container 70 described below. The downstream end of the branch pipe 55 is connected to the second inlet pipe 56. Note that the branch pipe 55 is not limited to a rigid pipe, and may be a hose at least a portion of which is flexible. The second inlet pipe 56 is a pipe branching off from the first inlet pipe 52. By connecting the second inlet pipe 56 to the branch pipe 55, the additive is added to the air flowing through the second inlet pipe 56. The second spinning pipe 57 is connected to the downstream end of the second inlet pipe 56 and is a pipe passing through an area where multiple spinning units 2 are arranged. The second spinning pipe 57 branches out according to the positions of the plurality of spinning units 2, and supplies air containing additives to each of the spinning units 2.

[0057] The first introduction pipe 52 and the first spinning pipe 53 are connected via a first coupler 58. The mounting position of the first coupler 58 is adjustable. Specifically, an elongated hole is formed in the first coupler 58, and the mounting position of the first coupler 58 can be adjusted depending on the position of the elongated hole to which the fixture is fixed. This makes it possible to absorb any deviation in the relative positions of the first introduction pipe 52 and the first spinning pipe 53. The second introduction pipe 56 and the second spinning pipe 57 are connected via a second coupler 59. The second coupler 59 has the same configuration as the first coupler 58 and can achieve the same effects.

[0058] A part of the piping that constitutes the air piping 50 of this embodiment (specifically, the front part other than the branch piping 55) is a non-flexible piping. This makes it possible to reduce pressure loss when passing through the air piping 50.

[0059] The layout of the air piping 50 will be described later.

[0060] Next, the components of the air treatment system will be described. The spinning machine 1 includes an air filter 61, a regulator 62, and a storage container 70 as components for treating the air to be supplied to the spinning units 2.

[0061] The air filter 61 is provided in the first inlet pipe 52. The air filter 61 purifies the air supplied to the spinning unit 2 by collecting unwanted substances such as dust and oil contained in the air supplied to the spinning unit 2. In this embodiment, two air filters 61 are arranged side by side along the air path. The two air filters 61 may be of the same specifications or may be different. Furthermore, by providing two air filters 61, when one air filter 61 deteriorates, only the deteriorated air filter 61 needs to be replaced. This reduces replacement costs. However, a configuration in which only one air filter 61 is provided may also be used.

[0062] The regulator 62 is provided in the first inlet pipe 52. The regulator 62 is disposed downstream of the air filter 61. The regulator 62 adjusts the pressure of the air supplied to the spinning unit 2. In detail, since the compressed air supplied from the facility pipe 51 has a high pressure, the regulator 62 changes the pressure so that it becomes a pressure suitable for supplying to the spinning unit 2.

[0063] The branch pipe 55 described above branches off from the air path between the air filter 61 and the regulator 62. The branch pipe 55 is a path for adding additives, and is located upstream of the regulator 62 because it does not need to reduce the pressure to a level suitable for supplying to the spinning unit 2.

[0064] The storage container 70 is a container for storing an additive. The additive is a liquid that is added to the air supplied to the spinning unit 2. The additive is, for example, water or a chemical that prevents the accumulation of oil in the air spinning device 6. The additive may also be, for example, a chemical that imparts at least one of the following functions to the yarn 15: antibacterial, deodorizing, odor prevention, wax, etc.

[0065] There are various methods for adding the additive to the air, but for example, a mist of the additive may be generated by supplying compressed air into the additive liquid in the storage container 70. Alternatively, the additive may be sprayed into the air pipe.

[0066] The storage container 70 includes a main body 71, an opening 72, and a closing portion 73. The main body 71 is a container-like portion that can store an additive. The opening 72 is an opening at the top of the main body 71 and is used, for example, to refill the additive. The closing portion 73 is a lid that closes the opening 72.

[0067] Furthermore, the storage container 70 is placed on a cart 75. This configuration allows the operator to easily move the storage container 70.

[0068] As shown in FIG. 6, the storage container 70 further includes a protrusion 76 and a mark 77. The protrusion 76 is connected to the main body 71 via a block 78. A through-hole is formed in the block 78, and the block 78 is connected to the storage region of the main body 71. The protrusion 76 also houses a pin 76a. The pin 76a is biased downward by a spring (not shown). When the pressure received by the pin 76a exceeds the biasing force of the spring, the pin 76a protrudes upward. Note that the pin 76a is a different color from the main body of the protrusion 76, making it easy for an operator to visually recognize that the pin 76a has protruded. When the operator cannot visually recognize the pin 76a, this indicates that the pressure in the storage container 70 is insufficient, and therefore, a pressure abnormality can be easily detected.

[0069] The markings 77 are arranged around the opening 72. The markings 77 are made of a material that is a different color from the surrounding area of ​​the opening 72. The markings 77 are, for example, stickers, but may also be components inserted into the recesses to which the markings are to be attached. As shown in FIG. 7 , in a side view, the markings 77 are visible before the closure portion 73 is attached. While the closure portion 73 is being attached, some of the markings 77 are hidden by the closure portion 73, but some of the markings 77 are still visible. When the closure portion 73 is attached, the markings 77 are completely hidden by the closure portion 73. Furthermore, for example, if the closure portion 73 is at an angle to the opening 72, the closure portion 73 will not be properly attached. In this case, some of the markings 77 are still visible. In other words, by visually checking the markings 77, the operator can easily confirm whether the closure portion 73 is attached to the appropriate depth and in the appropriate orientation.

[0070] The layout of the air filter 61, the regulator 62, and the storage container 70 will be described later.

[0071] Next, the parts that are operated or visually recognized by the operator will be described. The spinning machine 1 is equipped with a display device 81, a control operation unit 82, an addition operation unit 83, and a spinning pressure meter 84 as these parts.

[0072] The display device 81 displays information related to spinning. The display device 81 is connected to a processing device (not shown) and displays images generated by the processing device. The display device 81 is, for example, a liquid crystal display or an organic EL display. The information related to spinning includes, for example, the operating status of the spinning unit 2, setting values ​​for spinning conditions, and a screen for issuing commands to the spinning unit 2.

[0073] The control operation unit 82 is arranged around the display device 81. The control operation unit 82 includes keys, dials, etc. that are operated by an operator. Operations performed on the control operation unit 82 include, for example, an operation for displaying information about spinning on the display device 81, an operation for changing set values ​​for spinning conditions, etc., and an operation for issuing commands to the spinning unit 2. The control operation unit 82 may be a touch panel that is integrated with the display device 81.

[0074] The addition operation unit 83 includes an operation tool operated by an operator. The operation performed on the addition operation unit 83 is to adjust the amount of additive supplied. For example, operating the addition operation unit 83 changes the pressure of the compressed air supplied to the storage container 70, which changes the amount of additive supplied accordingly. In addition, the spinning pressure meter 84 displays the detection result of the pressure of the air used by the air spinning device 6 for spinning. The operator operates the addition operation unit 83 while watching the spinning pressure meter 84.

[0075] Next, a description will be given of the internal layout of the component housing box 20. In the following description, the upstream and downstream of the air flow will simply be referred to as "upstream" and "downstream".

[0076] The facility piping 51 is introduced into the inner area 21 from the top surface of the component housing box 20. An air filter 61 and an adjuster 62 are disposed downstream thereof. The air filter 61 and the adjuster 62 are disposed in the upper area 22 and along the first side surface. Disposed along the first side surface means that the air filter 61 and the adjuster 62 are closest to the first side surface among the four side surfaces and the distance between the first side surface and the component does not change significantly. Furthermore, in this embodiment, the longitudinal direction (axial direction) of the air filter 61 is parallel to the first side surface, and the longitudinal direction of the adjuster 62 is parallel to the first plane.

[0077] Downstream of the adjuster 62, the first inlet pipe 52 changes direction by 90 degrees and is arranged along the front surface of the component housing box 20. In other words, the first inlet pipe 52 is arranged parallel to the first direction. After that, the first inlet pipe 52 bends 90 degrees to the rear surface side, and then bends 90 degrees again along the first direction to be connected to the first spinning pipe 53.

[0078] Furthermore, the first inlet pipe 52 is connected to the first spinning pipe 53 with little or no change in its height position. In other words, the entire first inlet pipe 52 from its upstream end to its downstream end is located in the upper region 22. Alternatively, the height of the connection point between the first inlet pipe 52 and the first spinning pipe 53 is referred to as the reference height (FIG. 4). Note that the height of various pipes refers to the height of the center of the pipe in the height direction (i.e., the axial center or the center of the flow path cross section). The entire first inlet pipe 52 from its upstream end to its downstream end is positioned at the same height as the reference height. Note that the entire first inlet pipe 52 from its upstream end to its downstream end or a portion thereof may be positioned higher than the reference height.

[0079] The branch pipe 55 branches between the air filter 61 and the regulator 62, and then passes through the storage container 70 in the lower region 23. Therefore, the branch pipe 55 includes a portion disposed in the lower region 23. The second inlet pipe 56, like the first inlet pipe 52, is disposed in the upper region 22 at a position higher than the reference height.

[0080] As described above, in this embodiment, most of the air piping 50 (all except for the branch piping 55) connecting the facility piping 51 and the first spinning piping 53 (or the second spinning piping 57) is located in the upper region 22 and at a position higher than the reference height. Therefore, the piping can be shortened, which makes it possible to secure space for arranging components and reduce pressure loss.

[0081] A storage space for the storage container 70 and the yarn splicing carriage 3 is formed in the lower region of the component storage box 20. Specifically, the storage space for the storage container 70 is formed in the region of the lower region 23 closer to the first side surface. Here, if the drive devices for driving the winding drum and the traverse device are shared among multiple spinning units 2, these drive devices may be disposed in, for example, the component storage box 20. In contrast, in the spinning machine 1 of this embodiment, the drive device for driving the winding drum and the drive device for driving the traverse device are provided for each spinning unit 2. Therefore, the component storage box 20 of this embodiment does not need to have such drive devices, and therefore the storage space can be made larger. As a result, for example, a layout in which the storage container 70 is disposed in the internal space of the component storage box 20 can be easily realized. Furthermore, as shown in FIG. 3 , there is no lower end frame on the first side surface. Therefore, the storage container 70 can be easily moved to the outside of the spinning machine 1 using a carriage 75.

[0082] Furthermore, a storage space for the yarn splicing carriage 3 is formed closer to the second side surface than the storage space for the storage container 70. A notch 43a is formed in the unit-side panel 43, which is the boundary between the component storage box 20 and the spinning unit 2. The notch 43a is sized to allow the yarn splicing carriage 3 to pass through. This allows the yarn splicing carriage 3 to travel by itself from the area where the spinning unit 2 is located to the lower area 23 of the component storage box 20.

[0083] The boundary between the upper region 22 and the lower region 23 can be set, for example, as follows. For example, if a horizontal plate is provided to separate the upper region 22 and the lower region 23, the upper region 22 is above the horizontal plate, and the lower region 23 is below the horizontal plate. From another perspective, the upper region 22 is above the upper end of the storage container 70, or above the upper end of the yarn splicing cart 3 housed in the housing space. From yet another perspective, the upper region 22 is above the lower end of the air filter 61, or above the lower end of the adjuster 62.

[0084] Moreover, the display device 81, the control operation unit 82, the addition operation unit 83, and the spinning pressure meter 84 are all arranged on the front side. This allows the arrangement of devices that require the operator to operate or see to be concentrated, thereby reducing the operator's workload. In particular, the display device 81 is arranged along the air piping 50 (specifically, the first introduction piping 52). In other words, the display device 81 is arranged so that one of the four sides that form the outline of the display device 81 is close to and parallel to the air piping 50.

[0085] Furthermore, since the display device 81, which must be visible to the operator, is disposed in the upper region 22, the display device 81 can be disposed in a position that is easy for the operator to see. Furthermore, since the display device 81 and the control operation unit 82 have a high affinity with each other, the control operation unit 82 is disposed near the display device 81. Furthermore, the addition operation unit 83 and the spinning pressure meter 84 are both disposed in the lower region 23. Since the spinning pressure meter 84 must be taken into consideration when operating the addition operation unit 83, operability for the operator can be improved by disposing the addition operation unit 83 and the spinning pressure meter 84 on the same surface and in the lower region 23.

[0086] Furthermore, the side door 41 is arranged on the side of the upper area 22 where the air filter 61, which requires high maintenance, is located, and the front panel 44 is arranged on the side where the display device 81, which requires low maintenance, is located. Therefore, it is easy to access the side where maintenance is most necessary. Furthermore, the front door 45 is arranged on the side of the lower area 23 where the addition operation unit 83, which requires operation by the operator, is located, and the side panel 42 is arranged on the side where operation by the operator is least necessary. Therefore, it is easy to access the side where operation by the operator is most necessary.

[0087] As described above, the spinning machine 1 of this embodiment includes multiple spinning units 2, an air pipe 50, a component storage box 20, an air filter 61, a regulator 62, and a display device 81. The spinning units 2 are arranged in a parallel line and produce yarn 15 by spinning. The air pipe 50 supplies air to the multiple spinning units 2. The component storage box 20 is arranged adjacent to the spinning units 2, has a first side surface, and has an inner area 21 formed therein. The air filter 61 is arranged in the inner area 21 along the first side surface and purifies the air supplied to the spinning units 2. The regulator 62 is arranged in the inner area 21 along the first side surface and adjusts the pressure of the air supplied to the spinning units 2. The display device 81 is arranged in the component storage box 20 along the air pipe 50 and displays information related to spinning. The inner area of ​​the component storage box 20 has a lower area 23 and an upper area 22. The lower region 23 is provided with at least one of a space for accommodating a yarn splicing cart 3 that travels in a parallel direction between the multiple spinning units 2 and a space for accommodating a storage container 70 that stores additives to be supplied to the spinning units 2. The upper region 22 is located higher than the lower region 23 and is provided with an air filter 61 and an adjuster 62. The air piping 50 includes a first spinning piping 53 and a first inlet piping 52. The first spinning piping 53 is located in the space where the multiple spinning units 2 are located and supplies air to each of the spinning units 2. The first inlet piping 52 is provided with an air filter 61 and an adjuster 62, and the first inlet piping 52 directly supplies air that has passed through the air filter 61 and the adjuster 62 to the first spinning piping 53. The height of the connection between the first inlet piping 52 and the first spinning piping 53 is referred to as the reference height, and the first inlet piping 52 is located in the upper region and at a height equal to or higher than the reference height.

[0088] Since the first inlet pipe 52 is in the upper region and above the reference height, the pipe can be shortened. As a result, the piping space can be reduced, and pressure loss can be reduced. Furthermore, by arranging the first inlet pipe 52 in the upper region 22, the lower region 23 can be made wider, thereby forming the above-mentioned storage space. In addition, by providing the display device 81 along the air pipe 50, the space within the component housing box 20 can be effectively utilized. As a result, components can be arranged efficiently and rationally within the component housing box 20.

[0089] In the spinning machine 1 of this embodiment, the first side surface is the surface of the end of the component housing box 20 in the parallel direction, and is the surface opposite to the side on which the first spinning pipe 53 is located.

[0090] This prevents the first spinning pipe 53 and the spinning unit 2 from getting in the way when performing maintenance on the air filter 61 or the regulator 62. Also, keys for operator operation may be located on another side of the parts storage box 20, and by avoiding that side, the placement of the keys is not obstructed.

[0091] In the spinning machine 1 of this embodiment, the part storage box 20 has a door at a position corresponding to the first side that can be switched between an open state that allows access to the internal area and a closed state that does not allow access to the internal area.

[0092] This allows access to the air filter 61 or the regulator 62 simply by opening the side door 41, making maintenance easy.

[0093] In the spinning machine 1 of this embodiment, the second spinning pipe 57 that supplies the air to which the additive has been added corresponds to the spinning pipe. The air to which the additive has been added is supplied from the second inlet pipe 56 to the second spinning pipe 57.

[0094] This allows air containing the additive to be supplied to the spinning unit 2.

[0095] In the spinning machine 1 of this embodiment, the air pipe 50 has a branch pipe 55 that branches off from the first inlet pipe 52 in the internal region of the component housing box 20. The branch pipe 55 is supplied with additives from a storage container 70. The branch pipe 55 is connected to a second inlet pipe 56.

[0096] As a result, the connection point between the first introduction pipe 52 and the branch pipe 55 is not located outside the component housing box 20, so the space required outside the component housing box 20 can be reduced.

[0097] The spinning machine 1 of this embodiment includes an addition operation unit 83 that allows an operator to adjust the amount of additive supplied. The addition operation unit 83 is disposed on the surface of the component housing box 20 at the end in a direction perpendicular to the parallel direction in a plan view, on which the display device 81 is disposed.

[0098] This allows the addition operation unit 83 to be located at a position that is easily accessible to the operator, making it easy to make adjustments regarding the supply of additives.

[0099] The spinning machine 1 of this embodiment is provided with a spinning pressure meter 84 that displays the detection result of the air pressure related to spinning in the spinning unit 2. The spinning pressure meter 84 is arranged on the surface of the component storage box 20 on which the addition operation unit 83 is arranged.

[0100] This allows the operator to operate the addition operation unit 83 while watching the spinning pressure meter 84 .

[0101] In the spinning machine 1 of this embodiment, the storage container 70 has an opening 72, a closing portion 73, and a mark 77. The closing portion 73 closes the opening 72. The mark 77 is disposed in a position that is hidden by the closing portion 73 when the opening 72 is closed, when viewed in a predetermined direction.

[0102] This allows easy determination of whether closure portion 73 is properly attached based on whether or not mark 77 is visible.

[0103] The spinning machine 1 of this embodiment includes a protrusion 76 attached to the storage container 70. The protrusion 76 protrudes when the pressure inside the storage container 70 reaches or exceeds a threshold value.

[0104] This makes it possible to easily detect the occurrence of a pressure abnormality. [Explanation of symbols]
