Description

  The present invention mainly relates to an arrangement configuration of a drive source that drives a traverse device included in a yarn winding machine.

  A yarn winder that winds a yarn to form a package is known. As this type of yarn winding machine, for example, there are spinning machines described in Patent Document 1 and Patent Document 2. As disclosed in Patent Document 1 and Patent Document 2, this type of spinning machine is provided with a large number of spinning units arranged on the machine base body for winding the yarn.

  The yarn winding machine includes a traverse device that traverses the yarn when winding the yarn on a package. The spinning machine described in Patent Literature 1 discloses a traverse device configured to reciprocate a yarn guide in all spinning units simultaneously by reciprocating a long traverse rod.

JP 2004-250122 A JP-A-8-246275

  Patent document 1 is disclosing the cam box which is a drive source of a traverse rod. Since this cam box reciprocates the traverse rod at high speed, an impact is generated when the reciprocation of the traverse rod is reversed. Therefore, a large vibration is generated in the cam box during driving of the traverse device. In particular, when the traverse rod is provided across a plurality of spinning units as in Patent Document 1 and the traversing of the yarns in all the spinning units is performed in common, the traverse rod itself becomes heavy, so the vibration is very large. Become.

  As described above, since vibration is generated in the cam box, there is a problem in that the cam box moves as it is. Therefore, it is necessary to fix the cam box somewhere. In a conventional spinning machine, the cam box is fixed to a drive end frame arranged at one end of the spinning machine. Thereby, it can prevent that a cam box moves by vibration. In addition, according to this configuration, since the cam box can be transported integrally with the drive end, there is an advantage that the installation work of the spinning machine can be simplified.

  However, in the above configuration in which the cam box is fixed to the frame, the vibration of the cam box is transmitted to the peripheral device through the frame. In particular, in recent years, the spinning speed has been improved and the traverse speed has been increased, so that the vibration generated in the cam box has increased. For this reason, the peripheral device may be damaged by the vibration of the cam box.

  The present invention has been made in view of the above circumstances, and a main object thereof is to provide a yarn winding machine in which adverse effects due to vibrations generated in a drive source of a traverse device are reduced.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to an aspect of the present invention, there is provided the following configuration in a yarn winding machine in which a plurality of yarn winding units that wind a yarn to form a package are arranged in parallel along the longitudinal direction of the machine base. That is, the yarn winding machine includes a traverse mechanism, a drive unit, a vibration relief unit, and a storage frame. The traverse mechanism is provided across the plurality of yarn winding units, and commonly performs traversing of the yarn taken up by each of the yarn winding units. The drive unit reciprocates the traverse mechanism. The vibration relief unit releases vibrations generated by the drive unit driving the traverse mechanism. The housing frame houses the drive unit. The drive part and the vibration relief part are provided independently of the housing frame.

  As described above, the drive unit is provided independently of the housing frame, and the vibration relief unit that releases the vibration of the drive unit other than the housing frame is provided, so that the vibration of the drive unit can be prevented from being transmitted to the housing frame. . As a result, it is possible to prevent the housing frame from being damaged by the vibration of the drive unit, and as a result, the durability of the yarn winding machine is improved.

  The yarn winding machine is preferably configured as follows. That is, the yarn winding machine further includes an operation unit common to the plurality of yarn winding units and an air supply unit that supplies air to the plurality of yarn winding units. At least one of the operation unit and the air supply unit is attached to the housing frame.

  That is, since the drive unit is provided independently of the storage frame, vibration of the drive unit can be prevented from being transmitted to the storage frame, so that the vibration is applied to the operation unit and the air supply unit attached to the storage frame. Is not transmitted. Therefore, it is possible to prevent the operation unit and the air supply unit from being damaged by the vibration of the drive unit.

  In the above-described yarn winding machine, it is preferable that the vibration relief portion is fixed to an installation surface of the yarn winding machine.

  By fixing the vibration relief portion to the installation surface in this manner, the vibration of the drive unit can be released to the installation surface. Moreover, as a result of the vibration relief portion being fixed to the installation surface, the drive unit can be reliably fixed to the installation surface. As a result, the yarn traversing by the traverse mechanism is stabilized, and a high-quality package can be formed.

  The yarn winding machine is preferably configured as follows. That is, the storage frame includes a lower frame member that constitutes at least a part of the lower portion of the storage frame. The lower frame member is detachable from the main body of the housing frame.

  Since the lower frame member is detachably provided in this way, when the vibration relief portion is fixed to the installation surface, the lower frame member can be removed and the operation can be performed, so that the fixing operation is facilitated. In addition, after the vibration relief portion is fixed, the rigidity of the housing frame can be increased by attaching the lower frame member to the housing frame body.

  The yarn winding machine is preferably configured as follows. That is, the yarn winding unit includes a yarn supplying unit that supplies the yarn and a winding unit that winds the yarn traversed by the traverse mechanism onto the package. The yarn feeding section is arranged at the upper part of the machine base, and the traverse mechanism and the winding part are arranged at the lower part of the machine base.

  Thus, in the case of a layout in which the traverse mechanism is arranged at the lower part of the machine base, the drive unit of the traverse mechanism can be arranged at a low position. Therefore, the drive unit can be firmly fixed to the installation surface.

  The yarn winding machine is preferably configured as follows. That is, the traverse mechanism includes a plurality of traverse guides that engage with the yarn taken up by the respective yarn winding units, and a traverse rod to which the plurality of traverse guides are attached. The drive unit includes a cam drum, a motor that rotationally drives the cam drum, and a cam mechanism that converts the rotational motion of the cam drum into a reciprocating motion and outputs the reciprocating motion from an output shaft. The output shaft and the traverse rod are connected.

  According to the configuration of the present invention, in the traverse type yarn winding machine as described above, it is possible to prevent vibration from being transmitted to the entire yarn winding machine and to form a package stably.

  The yarn winding machine is preferably configured as follows. That is, the drive unit includes an oil storage unit, an oil recovery unit, a return hole, and a cover member. The oil reservoir stores oil supplied to the cam mechanism. The oil recovery unit recovers oil attached to the output shaft. The return hole returns the oil recovered by the oil recovery part to the oil storage part. The cover member covers the return hole, and prevents oil scattered by the cam mechanism from splashing on the return hole.

  Thus, by providing the oil recovery unit, oil leakage from the output shaft of the drive unit can be reduced. In addition, since the cover member is provided, it is possible to prevent oil from splashing into the return hole, so that the oil from the return hole can be smoothly returned to the oil reservoir.

  The yarn winding machine is preferably configured as follows. That is, the drive unit includes a base body, a cam mechanism housing unit that houses at least the cam drum and the cam mechanism, and two suspension support members that support the cam mechanism housing unit from the base body. Prepare. The two suspension support members are attached to the base body so as to be symmetric with respect to the center of gravity of the cam mechanism housing portion.

  By supporting the cam mechanism housing portion in this manner, the base body can receive vibration from the cam mechanism housing portion uniformly.

  The yarn winding machine is preferably configured as follows. That is, each of the yarn winding units includes a yarn supplying unit. The yarn supplying unit includes a draft device that drafts a fiber bundle, and an air spinning device that twists the fiber bundle drafted by the draft device with an air flow to generate a spun yarn. The spun yarn supplied from the yarn supplying section is wound around the package by each of the yarn winding units while traversing by the traverse mechanism.

  That is, since the pneumatic spinning device can perform spinning at a high speed, the traverse speed of the traverse mechanism is also increased, and the drive unit is likely to generate vibration. Therefore, in the yarn winding machine equipped with such an air spinning device, by adopting the configuration of the present invention, the effect of the vibration relief part that prevents the vibration of the drive part from being transmitted to surrounding equipment is particularly suitable. It can be demonstrated.

  In the following description, the direction in which the spinning units 6 are arranged side by side (directions indicated by “right” and “left” arrows in FIGS. 1 and 2) may be simply referred to as “left-right direction”. In addition, the direction orthogonal to the left-right direction and the up-down direction (vertical direction) (directions indicated by arrows “front” and “rear” in FIGS. 1 and 3) may be simply referred to as “front-rear direction”. As shown in FIG. 3, the spun yarn 15 generated by the spinning unit 6 travels on one side in the front-rear direction of the machine base body 2 when viewed in the left-right direction. Therefore, in the front-rear direction, the side on which the spun yarn 15 travels (right side in FIG. 3) when viewed from the machine base body 2 may be referred to as the front side and the opposite side may be referred to as the back side.

  The drive end box 3 is disposed at one end of the machine base body 2 in the left-right direction. As shown in FIG. 5, a draft drive unit 31 and a traverse drive unit (drive unit) 32 that are common drive sources for the plurality of spinning units 6 are arranged in the drive end box 3.

  The drive end box 3 is supplied with compressed air from a compressed air source (not shown) via a compressed air supply pipe 33. As shown in FIG. 5, an air supply unit 34 that appropriately adjusts the compressed air (air) and supplies it to each part of the spinning machine 1 is disposed in the drive end box 3. The air supply unit 34 includes a regulator 35 for adjusting the pressure of the compressed air. The compressed air adjusted to an appropriate air pressure by the air supply unit 34 is supplied to each part of the spinning machine 1 through a duct or a tube (not shown).

  As shown in FIGS. 1 and 4, an operation unit 18 is provided on the front side of the drive end box 3. The operation unit 18 includes a display screen capable of displaying information related to each spinning unit 6, setting operation tools (operation buttons, operation dial, etc.) for performing various settings, and the like. The operation unit 18 is configured to be communicable with each spinning unit 6 and centrally manages information related to the plurality of spinning units 6 included in the spinning machine 1. The operation unit 18 can transmit a control signal to the plurality of spinning units 6 provided in the spinning machine 1 at once or individually. Therefore, the operator of the spinning machine 1 can intensively operate the plurality of spinning units 6 by the operation unit 18.

  A bobbin stocker 4 is disposed at the end of the machine base body 2 opposite to the drive end box 3 in the left-right direction. The bobbin stocker 4 is configured to be able to hold a plurality of empty winding bobbins 16.

  As shown in FIG. 2, a blower box 5 is disposed on the back side of the bobbin stocker 4. A negative pressure source (not shown) is disposed in the blower box 5. As shown in FIG. 3, negative pressure ducts 19, 20, and 21 are arranged in the machine base body 2 along the left-right direction. The negative pressure ducts 19, 20, and 21 are connected to the negative pressure source, and the negative pressure ducts 19, 20, and 21 are maintained at a negative pressure by the negative pressure source. A negative pressure can be supplied to each part of the spinning machine 1 through the negative pressure ducts 19, 20, and 21.

  The yarn supplying section 9 of each spinning unit 6 is arranged at the upper part of the machine base body. The yarn supplying unit 9 includes a draft device 10 and a spinning unit 11. The draft device 10 is provided near the upper end of the machine base body 2. The draft device 10 drafts (stretches the fibers) a sliver (fiber bundle raw material) 22 supplied from a sliver case (not shown) through a sliver guide until a predetermined width is reached.

  The draft device 10 includes a plurality of draft rollers. Each draft roller forms a pair of draft rollers in pairs. The draft device 10 is a four-wire type having four draft roller pairs in order from the upstream side: a pair of back rollers 23 and 27, a pair of third rollers 24 and 28, a pair of middle rollers 25 and 29, and a pair of front rollers 26 and 30. It is configured as a draft device. In each draft roller pair, a draft roller positioned on the front side in the front-rear direction is referred to as a top roller, and a draft roller positioned on the back side is referred to as a bottom roller. As shown in FIG. 3, the top rollers are, in order from the upstream side, a back top roller 23, a third top roller 24, a middle top roller 25 on which a rubber apron belt is mounted, and a front top roller 26. On the other hand, the bottom rollers are, in order from the upstream side, a back bottom roller 27, a third bottom roller 28, a middle bottom roller 29 on which a rubber apron belt is mounted, and a front bottom roller 30.

  Each spinning unit 6 includes an unillustrated electric motor for rotationally driving the back bottom roller 27 and the third bottom roller 28. Thereby, the back bottom roller 27 and the third bottom roller 28 can be rotationally driven for each spinning unit 6. The middle bottom roller 29 and the front bottom roller 30 are driven by a draft driving unit 31 disposed in the drive end box 3 described above.

  The draft driving unit 31 is configured to drive the middle bottom roller 29 and the front bottom roller 30 of the plurality of spinning units 6 provided in the spinning machine 1 in common. Specifically, as shown in FIGS. 1 and 2, the spinning machine 1 includes a first line shaft 36 and a second line shaft 37 arranged along the left-right direction. The front bottom roller 30 of each spinning unit 6 is coaxially fixed to the first line shaft 36. A middle bottom roller 29 of each spinning unit 6 is coaxially fixed to the second line shaft 37. End portions of the first line shaft 36 and the second line shaft 37 are connected to a draft drive unit 31 in the drive end box 3. The draft drive unit 31 is configured to rotationally drive the first line shaft 36 and the second line shaft 37 at a predetermined rotational speed. With the above configuration, the front bottom roller 30 and the middle bottom roller 29 are driven simultaneously in all the spinning units 6.

  On the other hand, each of the top rollers 23, 24, 25, and 26 is supported so as to be rotatable about its axis via a bearing (not shown). The top rollers 23, 24, 25, and 26 are urged toward the bottom rollers 27, 28, 29, and 30 that oppose the urging members by a biasing member (not shown).

  With the above configuration, the draft device 10 sandwiches the sliver 22 between the rotating top rollers 23, 24, 25, and 26 and the bottom rollers 27, 28, 29, and 30, and conveys the sliver 22 toward the downstream side. be able to. The draft device 10 is configured such that the rotational speed of the downstream draft roller pair increases. Accordingly, the fiber bundle 14 (or sliver 22) is stretched (drafted) while being conveyed between the draft roller pair and the draft roller pair. Since the degree to which the fiber bundle 14 is drafted can be changed by appropriately setting the rotation speed of each of the bottom rollers 27, 28, 29, and 30, the draft device 10 allows the fiber bundle 14 to have a desired fiber width. Can be drafted. The rotation speed of each roller is appropriately changed according to the spinning conditions (winding conditions) such as the type of fiber and the thickness of the spun yarn 15 to be spun.

  The spinning unit 11 is arranged immediately downstream of the pair of front rollers 26 and 30. The fiber bundle 14 drafted by the draft device 10 is supplied to the spinning unit 11. The spinning unit 11 includes an air spinning device 41 that twists the fiber bundle 14 using a swirling airflow. The air spinning device 41 twists the fiber bundle 14 supplied from the draft device 10 to generate the spun yarn 15.

  As shown in FIG. 6, the air spinning device 41 mainly includes a nozzle block 43, a hollow guide shaft body 44, and a fiber guide portion 45.

  A spinning chamber 46 is formed between the nozzle block 43 and the hollow guide shaft body 44. The nozzle block 43 is formed with an air ejection nozzle 47 that ejects air into the spinning chamber 46. The fiber guide 45 is formed with an introduction port 48 for introducing the fiber bundle 14 into the spinning chamber 46. The air ejection nozzle 47 is configured to eject air into the spinning chamber 46 and generate a swirling airflow. With this configuration, the fiber bundle 14 supplied from the draft device 10 is guided into the spinning chamber 46 by the fiber guide 45 having the introduction port 48. In the spinning chamber 46, the fiber bundle 14 is swung around the hollow guide shaft body 44 by the swirling airflow, and thereby twisted to become the spun yarn 15. The spun yarn 15 to which the twist is applied passes through a yarn passage 49 formed at the center of the hollow guide shaft body 44 and is sent to the outside of the pneumatic spinning device 41 from a downstream yarn outlet (not shown).

  The introduction port 48 is provided with a needle-shaped guide needle 50 having its tip disposed in the spinning chamber 46. The fiber bundle 14 introduced from the introduction port 48 is guided into the spinning chamber 46 so as to be wound around the guide needle 50. Thereby, the state of the fiber bundle 14 introduced into the spinning chamber 46 can be stabilized. Further, since the fiber bundle 14 is guided so as to be wound around the guide needle 50 in this way, even if twist is added to the fiber in the spinning chamber 46, the twist propagates upstream from the fiber guide portion 45. Is prevented. Thereby, the twist by the spinning unit 11 can be prevented from affecting the draft device 10. However, the guide needle 50 may be omitted, and the function of the guide needle 50 may be achieved by the downstream end portion of the fiber guide portion 45.

  Note that compressed air (air) for generating a swirling airflow in the air spinning device 41 is supplied from the air supply unit 34 arranged in the drive end box 3. As described above, the air supply unit 34 includes the regulator 35 that adjusts the air pressure of the compressed air. By appropriately adjusting the regulator 35 in advance, the compressed air can be appropriately supplied to the pneumatic spinning device 41, and thus the swirling airflow can be appropriately generated in the pneumatic spinning device 41. Thereby, spinning by the spinning part 11 can be performed appropriately.

  A winding unit 13 is disposed on the downstream side of the spinning unit 11 and below the machine body 2. The winding unit 13 includes a cradle arm 58 and a winding drum 59. The cradle arm 58 is configured to be swingable around the support shaft 57. The cradle arm 58 can rotatably support the winding bobbin 16 for winding the spun yarn 15. The take-up drum 59 is configured to be able to be driven in contact with the outer peripheral surface of the package 17 formed by winding the take-up bobbin 16 and the spun yarn 15 thereon. By driving the winding drum 59 by an electric motor (not shown), the winding bobbin 16 (or the package 17) that contacts the winding drum 59 can be rotated, and the spun yarn 15 can be wound on the winding bobbin 16. .

  As shown in FIG. 1, the spinning machine 1 has a traverse mechanism 60 for traversing the spun yarn 15 taken up by the take-up unit 13 of each spinning unit 6 at the lower part of the machine body 2. I have. The traverse mechanism 60 has a plurality of traverse guides 61 and a traverse rod 62.

  Each traverse guide 61 is arranged in the vicinity of the winding portion 13 of each spinning unit 6 and is configured to engage with the spun yarn 15 wound by the winding portion 13. The traverse rod 62 is disposed so that the longitudinal direction thereof is along the left-right direction, and is disposed over all the spinning units 6 included in the spinning machine 1. Each traverse guide 61 is fixed to a traverse rod 62. One end of the traverse rod 62 is connected to the traverse drive unit 32 in the drive end box 3. The traverse drive unit 32 is configured to reciprocate the traverse rod 62 left and right. As a result, the traverse guides 61 can be reciprocally driven all at once in all the spinning units 6. The traverse guide 61 in a state where the spun yarn 15 is engaged is reciprocated, and the take-up bobbin 16 is rotated by the take-up unit 13 so that the spun yarn 15 is wound while traversing, and a package having an appropriate shape is obtained. 17 can be formed.

  A yarn accumulating device 12 is provided between the spinning unit 11 and the winding unit 13. As shown in FIG. 3, the yarn storage device 12 includes a yarn storage roller 63 and an electric motor 64 that rotationally drives the yarn storage roller 63.

  The yarn accumulating roller 63 is configured so that a certain amount of spun yarn 15 can be wound around the outer peripheral surface and temporarily accumulated. With the spun yarn 15 wound around the outer peripheral surface of the yarn accumulating roller 63, the spun yarn 15 is pulled out from the air spinning device 41 of the spinning unit 11 at a predetermined speed by rotating the yarn accumulating roller 63 at a predetermined rotational speed. Can be conveyed downstream. Further, since the spun yarn 15 is temporarily stored on the outer periphery of the yarn storage roller 63, the yarn storage device 12 can function as a kind of buffer. Thereby, it is possible to eliminate a problem (for example, slack of the spun yarn 15) when the spinning speed in the spinning unit 11 and the winding speed in the winding unit 13 do not match for some reason.

  A yarn quality measuring device 65 is provided at a position between the spinning unit 11 and the yarn storage device 12. The spun yarn 15 spun by the spinning unit 11 passes through the yarn quality measuring device 65 before being wound by the yarn storage device 12. The yarn quality measuring device 65 is configured to monitor the thickness of the traveling spun yarn 15 using a capacitance type sensor (not shown). The yarn quality measuring device 65 is configured to transmit a yarn defect detection signal to a unit controller (not shown) when a yarn defect of the spun yarn 15 (a portion where the thickness of the spun yarn 15 is abnormal) is detected. Yes. The yarn quality measuring device 65 is not limited to the capacitance type sensor, and may be configured to monitor the thickness of the spun yarn 15 with a light transmission type sensor, for example. The yarn quality measuring device 65 may be configured to detect foreign matter contained in the spun yarn 15 as a yarn defect.

  A cutter (not shown) for cutting the spun yarn 15 immediately when a yarn defect of the spun yarn 15 is detected is disposed in the vicinity of the yarn quality measuring device 65. The spinning unit 6 may cut the spun yarn 15 by stopping the supply of air to the spinning unit 11 and interrupting the generation of the spun yarn 15 instead of the cutter.

  As shown in FIG. 1 and the like, the spinning machine 1 includes a yarn splicing cart 66 and a doffing cart (work cart) 67.

  In the machine base body 2, a yarn joining cart traveling rail 68 is laid along the left-right direction. The yarn joining cart traveling rail 68 is located on the back side of the yarn path of the spun yarn 15. The yarn joining cart 66 is configured to be able to travel along the yarn joining cart traveling rail 68.

  As shown in FIGS. 1 and 3, the yarn joining cart 66 includes a yarn joining device 69, a suction pipe 70, and a suction mouth 71. When the spun yarn 15 between the spinning unit 11 and the winding unit 13 is in a divided state due to yarn breakage, yarn cut, or the like in a certain spinning unit 6, the yarn joining cart 66 moves on the spinning unit traveling rail 68 on the spinning unit 68. Drive to 6 and stop. The suction pipe 70 sucks and captures the yarn end delivered from the spinning unit 11 and guides it to the yarn joining device 69 while rotating in the vertical direction about the axis. The suction mouse 71 sucks and captures the yarn end from the package 17 supported by the winding unit 13 and guides it to the yarn joining device 69 while rotating in the vertical direction about the axis. The negative pressure for the suction pipe 70 and the suction mouth 71 to generate a suction flow is supplied by the negative pressure source in the blower box 5. The yarn joining device 69 performs yarn joining by twisting the guided yarn ends together by a swirling airflow generated by compressed air. Thereby, the spun yarn 15 between the spinning unit 11 and the winding unit 13 can be set in a continuous state, and the winding of the spun yarn 15 onto the package 17 can be resumed. The compressed air for the yarn splicing device 69 to generate a swirling airflow is supplied from the air supply unit 34.

  As described above, since the yarn splicing carriage traveling rail 68 is laid on the back side of the yarn path, the yarn splicing carriage 66 runs on the back side of the yarn path, and performs the yarn splicing work from the position on the back side. Do. Thus, since the yarn splicing carriage 66 is located on the back side of the yarn path (that is, the position where the machine base body 2 is recessed), it is difficult to perform maintenance. Therefore, the spinning machine 1 of the present embodiment is configured such that the yarn splicing cart 66 can be extracted from the back surface of the machine base body 2. More specifically, as shown in FIG. 3, the negative pressure ducts 19, 20, and 21 for supplying negative pressure are arranged at a position higher or lower than the yarn joining cart 66, thereby The negative pressure duct is not arranged on the back side of the joint truck 66. An opening 110 is formed on a part of the back side of the machine base body 2 so as to communicate with a space in which the yarn joining cart 66 performs the yarn joining operation. Thereby, the yarn splicing cart 66 can be attached to and detached from the machine base body 2 through the opening portion 110. Therefore, the yarn splicing cart 66 can be extracted from the back side of the machine base body 2 for maintenance.

  When maintenance is performed on the yarn joining cart 66, sufficient maintenance may be performed if the back side of the yarn joining cart 66 can be accessed. In such a case, maintenance work can be performed via the opening 110 while the yarn splicing cart 66 is still attached to the machine base body 2. Therefore, the opening area of the opening part 110 does not have to be large enough to allow the yarn splicing carriage 66 to be extracted, and if the opening area is sufficient for the operator to perform maintenance. good.

  Further, on the front side of the machine body 2, a doffing cart traveling rail 39 is laid along the left-right direction. The doffing cart 67 is configured to travel along the doffing cart travel rail 39.

  The doffing cart 67 is configured to perform a doffing operation of the package 17 that is full. As shown in FIGS. 1 and 3, the doffing cart 67 includes an empty bobbin accommodating portion 38, a cradle operation arm 72, a thread drawing arm 73, and an empty bobbin supply arm 74. The empty bobbin accommodating portion 38 is configured to accommodate a plurality of empty winding bobbins 16. The thread pull-out arm 73 is configured to be extendable and contractable by an unillustrated air cylinder mechanism. An unillustrated catching section for sucking and catching the spun yarn 15 by a suction air flow is provided at the tip of the yarn draw-out arm 73.

  When the package 17 wound by a certain spinning unit 6 becomes full (a state in which a predetermined amount of the spun yarn 15 is wound), the doffing cart 67 runs on the doffing cart running rail 39 to the spinning unit 6. Then stop. Next, the cradle operation arm 72 removes the full-package 17 from the cradle arm 58 by operating the cradle arm 58 of the spinning unit 6. The removed full-winding package 17 is laid between the spinning unit 6 and the doffing carriage running rail 39 and dropped onto the package conveyor 75 to be received. In addition, a conveying mechanism may be provided in the doffing cart 67 and the full package 17 may be conveyed from the winding unit 13 to the package conveyor 75 by the conveying mechanism. As shown in FIG. 2, the package conveyor 75 is arranged along the left-right direction. The package conveyor 75 is configured to convey the full package 17 along the left-right direction. A package collection unit (not shown) is disposed at the end of the package conveyor 75 in the conveying direction of the full package 17. With the above configuration, the full package 17 can be automatically collected.

  Subsequently, the doffing cart 67 grips the empty winding bobbin 16 stocked in the empty bobbin accommodating portion 38 by the empty bobbin supply arm 74 and rotates the empty bobbin supply arm 74 so as to rotate the winding bobbin 16. The bobbin 16 is attached to the cradle arm 58 of the spinning unit 6. Before and after this, the yarn pull-out arm 73 of the doffing cart 67 sucks and captures the spun yarn 15 spun by the spinning unit 11, and the captured spun yarn 15 is attached to the cradle arm 58. Guide to the vicinity of the empty winding bobbin 16. In this state, the spun yarn 15 drawn from the spinning unit 11 is fixed to the take-up bobbin 16 by a known method such as bunch winding. In this state, by starting the rotation of the winding bobbin 16 by the winding unit 13, the winding of the spun yarn 15 around the new winding bobbin 16 can be started.

  Since the number of empty winding bobbins 16 that can be stocked in the empty bobbin accommodating portion 38 of the doffing cart 67 is limited, it is necessary to replenish the winding bobbins 16 at an appropriate timing. Therefore, the doffing cart 67 is configured to receive the supply of the winding bobbin 16 from the bobbin stocker 4 at an appropriate timing. That is, as shown in FIG. 2, the doffing carriage traveling rail 39 extends to a bobbin supply position 77 (a position indicated by a two-dot chain line in FIGS. 1 and 2). As shown in FIGS. 1 and 2, the bobbin supply position 77 is located on the front side of the machine base body 2 and is disposed adjacent to the bobbin stocker 4. The doffing cart 67 travels to the bobbin supply position 77 and stops as necessary. The take-up bobbin 16 is supplied from the bobbin stocker 4 to the doffing cart 67 stopped at the bobbin supply position 77.

  Next, the configuration of the drive end box 3 will be described in more detail.

  As shown in FIG. 4, the drive end box 3 has a configuration in which the front side, the side surface (and the back side, although not shown) are covered with a panel 78. The panel 78 is detachably attached to a frame 79 (see FIG. 5) of the drive end box 3.

  As shown in FIG. 5, the frame (accommodating frame) 79 of the drive end box 3 is configured by combining elongated frame materials. The frame material is not particularly limited. For example, a shape steel such as groove steel or a steel pipe can be used, and a sheet metal or the like may be used as long as it has a required strength. The draft drive unit 31, the traverse drive unit 32, and the air supply unit 34 are disposed inside the frame 79. The frame 79 includes reinforcing frame members 80, 81, and 82 that are disposed substantially horizontally in the middle portion in the vertical direction.

  The traverse drive unit 32 is disposed below the reinforcing frame members 80, 81, and 82. As shown in FIG. 7, the traverse drive unit 32 includes a cam box 90 having a built-in cam mechanism for reciprocating the traverse rod 62 in the left-right direction, and a traverse drive motor 91 that is a drive source of the cam box 90. And. With this configuration, the traverse rod 62 can be driven to reciprocate left and right at a predetermined speed by rotating the traverse drive motor 91 at a predetermined rotation speed.

  The air supply unit 34 is disposed below the reinforcing frame members 80, 81, and 82 and is attached to the frame 79. The air supply unit 34 includes an air device for appropriately supplying compressed air to each part of the spinning machine 1. Specifically, the air supply unit 34 includes a filter 83 for removing moisture from the compressed air supplied via the compressed air supply pipe 33. Further, as described above, the air supply unit 34 includes the regulator 35 for appropriately adjusting the air pressure of the compressed air.

  The draft drive unit 31 is disposed above the reinforcing frame members 80, 81, and 82 and is attached to the frame 79. As shown in FIG. 5, the draft driving unit 31 includes a first motor 84 for driving the first line shaft 36 and a second motor 85 for driving the second line shaft 37. Yes. The operation unit 18 is attached to the frame 79 on the front side of the draft drive unit 31.

  The frame 79 of the drive end box 3 is configured separately from the machine base body 2. Thereby, when the spinning machine 1 is installed, the machine base body 2 and the drive end box 3 can be carried separately.

  Next, the configuration of the traverse drive unit 32 will be described.

  As described above, the traverse drive unit 32 includes the cam box (cam mechanism housing unit) 90 and the traverse drive motor 91. Further, the traverse drive unit 32 includes a base body 92 that supports the cam box 90 and the traverse drive motor 91.

  The cam box 90 contains a cam drum 94 and a cam mechanism that converts the rotational motion of the cam drum 94 into a reciprocating motion. As shown in FIG. 8, the rotating shaft 95 of the cam drum 94 is rotatably supported by the cam box 90. As shown in FIG. 8, one end of the rotating shaft 95 protrudes from the cam box 90, and a pulley 96 is fixed to the end of the protruding rotating shaft 95. The pulley 96 receives a rotational driving force from the traverse driving motor 91 via a transmission belt (not shown). With this configuration, the cam drum 94 can be rotationally driven by the traverse drive motor 91.

  As shown in FIG. 8, an output shaft 93 is provided so as to protrude from the cam box 90. The output shaft 93 is arranged with its axis line along the left-right direction. The traverse rod 62 is connected to the output shaft 93. In the cam box 90, a cam mechanism for converting the rotation of the cam drum 94 into a reciprocating motion and causing the output shaft 93 to reciprocate along the axis is provided. With this configuration, the traverse rod 62 connected to the output shaft 93 can be reciprocated in the left and right directions, so that the traverse mechanism 60 can be reciprocated in the left and right directions, and the spinning yarns 15 can be traversed by the spinning units 6.

  Next, the cam mechanism will be described in detail. The cam mechanism includes a reciprocating spiral groove 97 formed on the outer periphery of the cam drum 94 and a shoe 98 that engages with the reciprocating spiral groove 97. The shoe 98 is fixed to the end of the output shaft 93. The output shaft 93 is supported by the cam box 90 so as to be slidable in the direction along the axis.

  With this configuration, when the cam drum 94 is driven to rotate, the shoe 98 engaged with the reciprocating spiral groove 97 moves as guided by the reciprocating spiral groove 97. Thereby, the shoe 98 reciprocates the output shaft 93 along the axis. With the above cam mechanism, the output shaft 93 can be reciprocated by converting the rotation of the cam drum 94 into reciprocating motion.

  Further, the bottom of the cam box 90 is an oil reservoir for storing oil 99 to be supplied to the cam mechanism. Therefore, it can be said that the cam box 90 also serves as an oil reservoir. The cam drum 94 is arranged so that a part of its outer periphery is immersed in the oil 99 in the oil reservoir. With this configuration, when the cam drum 94 rotates, oil is uniformly applied to the outer periphery of the cam drum 94 and the reciprocating spiral groove 97, and the cam mechanism can be driven to lubricate.

  Since the cam drum 94 is rotationally driven at a high speed by the traverse drive motor 91, oil falls on the output shaft 93 due to the rotational force of the cam drum 94. Since one end of the output shaft 93 protrudes to the outside of the cam box 90, when the output shaft 93 with oil attached is reciprocated, the oil attached to the output shaft 93 leaks to the outside of the cam box 90. End up.

  Therefore, in the spinning machine 1 of the present embodiment, an oil recovery unit 100 that recovers the oil attached to the output shaft 93 is provided. The oil recovery unit 100 is provided outside the cam box 90 and has a scraper 101 inside thereof. The scraper 101 is a rubber ring member disposed coaxially with the output shaft 93, and is disposed so as to wipe off oil adhering to the outer periphery of the output shaft 93. An oil return hole 102 that communicates the inside of the cam box 90 and the oil recovery unit 100 is formed in the side wall of the cam box 90. The oil recovered by wiping the output shaft 93 by the scraper 101 is returned from the oil recovery part 100 into the cam box 90 through the oil return hole 102.

  Since the shoe 98 and the output shaft 93 included in the cam mechanism are reciprocated at high speed, the oil adhering to the shoe 98 and the output shaft 93 is likely to be scattered toward the side wall surface of the cam box 90. If the oil thus scattered falls on the oil return hole 102, there may be a problem that the oil in the oil recovery unit 100 cannot be returned smoothly from the oil return hole 102.

  Therefore, in the spinning machine 1 of the present embodiment, the cover member 103 that covers the oil return hole 102 from the inside of the cam box 90 is disposed in order to prevent the oil scattered by the cam mechanism from falling on the oil return hole 102. In the present embodiment, the cover member 103 is a plate-like member, and is disposed so as to face at least the opening portion of the oil return hole 102. However, if the oil return hole 102 is completely blocked by the cover member 103, the oil in the oil recovery unit 100 cannot be returned to the cam box 90, so that the cover member 103 and the opening edge of the oil return hole 102 There is a gap between them. Further, the lower end portion of the cover member 103 is opened so that the oil from the oil return hole 102 can be dropped into the oil reservoir below the oil return hole 102.

  With the above configuration, oil scattered by the cam mechanism can be prevented from falling on the oil return hole 102, so that the oil recovered by the oil recovery unit 100 can be smoothly returned into the cam box 90 via the oil return hole 102. Can do. As a result, oil leakage from the reciprocating output shaft 93 can be reliably prevented.

  As described above, the cam box 90 is supported by the base body 92. The traverse drive unit 32 includes a suspension support member 104 for supporting the cam box 90 on the base body 92.

  The suspension support member 104 is a rod-shaped member disposed in parallel with the output shaft 93 and is provided through the cam box 90. Both ends of the suspension support member 104 penetrating the cam box 90 are fixed to the base body 92. The suspension support member 104 is configured to penetrate the cam box 90 at a position above the center of gravity of the cam box 90. As described above, the traverse driving unit 32 is configured to suspend and support the cam box 90 by the suspending support member 104.

  As shown in FIG. 9, in this embodiment, two suspension support members 104 are arranged, and the cam box 90 is supported by the two suspension support members 104. Thereby, the traverse drive unit 32 can stably support the cam box 90. In this embodiment, the two suspension support members 104 are symmetrical with respect to a vertical line passing through the center of gravity 90a of the cam box 90 when viewed in the longitudinal direction of the suspension support member 104 (FIG. 9). Has been placed. Here, the center of gravity 90a of the cam box 90 refers to the center of gravity including not only the cam box 90 itself but also the components housed in the cam box 90 (cam drum 94, shoe 98, output shaft 93, etc.). . Thus, the base body 92 causes vibration of the cam box 90 to be vibrated by supporting the cam box 90 with the two suspension support members 104 arranged symmetrically with respect to the center of gravity 90 a of the cam box 90. Can receive evenly.

  For example, as described in Patent Document 2, the conventional spinning machine is configured to extract the work carriage from the side of the machine base body in order to perform maintenance of the yarn joining carriage (work carriage). It was. Therefore, when the configuration in which the drive end box 3 is provided at the side end of the machine base as in the present embodiment is applied to the conventional spinning machine of Patent Document 2, the yarn joining cart 66 passes through the drive end box 3. It is necessary to pull it out. Therefore, the traverse drive unit 32 disposed in the drive end box 3 must be formed so as to avoid the yarn joining cart 66. For this reason, in the conventional spinning machine, the cam box 90 is formed in a shape that avoids interference with the yarn splicing carriage 66, for example, as shown in FIG. For this reason, as shown in FIG. 10, it is difficult to arrange the two suspension support members 104 symmetrically with respect to the center of gravity 90 a of the cam box 90.

  In this regard, in the spinning machine 1 of the present embodiment, as described above, the yarn splicing carriage 66 is configured to be extracted from the back side of the machine base body 2 and to be maintained. Therefore, according to the configuration of the present embodiment, it is not necessary to extract the yarn joining cart 66 from the side of the machine base body 2. That is, the spinning machine 1 of the present embodiment is not limited in that the cam box 90 must be formed avoiding the yarn splicing carriage 66. For this reason, in the spinning machine 1 of this embodiment, it is possible to arrange the two suspension support members 104 symmetrically with respect to the center of gravity 90a of the cam box 90 as described above.

  A vibration relief portion 105 is provided at the lower portion of the base body 92. Specifically, as shown in FIG. 9, the vibration relief portion 105 is provided via a fixing plate 106 fixed to the lower portion of the base body 92 and an insertion hole (not shown) formed in the fixing plate 106. The anchor bolt 107 is driven into the ground 109 (installation surface of the spinning machine 1). The base body 92 can be fixed to the ground 109 by driving the anchor bolt 107 into the ground 109. Accordingly, the traverse drive unit 32 can be fixed to the ground 109 so that the traverse drive unit 32 does not move due to vibration when the traverse drive unit 32 drives the traverse mechanism 60 to reciprocate.

  Further, as shown in FIG. 9, the vibration relief unit 105 is disposed on the front side and the back side of the traverse drive unit 32. In this way, by fixing both sides of the traverse drive unit 32 in the front-rear direction to the ground 109, the traverse drive unit 32 can be reliably fixed to the ground 109.

  In the spinning machine 1 of the present embodiment, the yarn supplying section 9 is disposed on the upper part of the machine base body 2, and the winding section 13 and the traverse mechanism 60 for winding the spun yarn 15 supplied from the yarn supplying section 9. Is arranged at the bottom of the machine base body 2. For this reason, the traverse drive unit 32, which is a drive source of the traverse mechanism 60, is also disposed in the lower part of the drive end box 3. In other words, in the present embodiment, the traverse driving unit 32 is disposed at a position close to the ground (installation surface) 109, so that the traverse driving unit 32 can be firmly fixed to the ground 109 by the anchor bolt 107. it can.

  In the present embodiment, the traverse drive unit 32 is disposed in the frame 79 of the drive end box 3 but is not connected to the frame 79. That is, the traverse drive unit 32 is provided independently of the frame 79. Further, the vibration relief portion 105 is also provided independently of the frame 79.

  With the above configuration, the vibration generated in the traverse drive unit 32 is not transmitted to the frame 79 of the drive end box 3 but is released to the ground 109 via the vibration release unit 105. In this way, by letting the vibration generated in the traverse drive unit 32 escape to the ground 109, other vibrations (for example, the operation unit 18) attached to the frame 79, the spinning unit 6 of the machine base body 2, etc. Can be prevented from being transmitted. Thereby, the durability of the entire spinning machine 1 can be improved.

  As shown in FIG. 2, in the spinning machine 1 of the present embodiment, the package conveyor 75 is formed to extend at least to the front side of the drive end box 3. For this reason, the drive end box 3 needs to be arranged on the back side of the package conveyor 75 in order to avoid interference with the package conveyor 75. On the other hand, since the traverse rod 62 for driving the traverse mechanism 60 must be connected to the traverse drive unit 32, the traverse drive unit 32 must be disposed on the side of the traverse mechanism 60.

  As described above, the arrangement of the drive end box 3 in the front-rear direction is limited, while the arrangement of the traverse drive unit 32 is also limited. For this reason, in the spinning machine 1 according to the present embodiment, there is a situation in which the traverse driving unit 32 must be arranged close to the front side of the frame 79 of the drive end box 3. However, as shown in FIG. 5, a lower frame member 86 is disposed along the left-right direction at the lower part on the front side of the frame 79. Therefore, if the traverse drive unit 32 is to be moved to the position near the front side in the frame 79, the lower frame member 86 becomes an obstacle. On the other hand, since the lower frame member 86 is necessary to ensure the rigidity of the frame 79, it cannot be omitted.

  Therefore, in the spinning machine 1 according to the present embodiment, as shown in FIGS. 7 and 9, a notch 108 that is recessed toward the back side is formed in the lower part of the front side of the base body 92 of the traverse drive unit 32. doing. The notch 108 is formed so as to avoid the lower frame member 86. As a result, the traverse drive unit 32 can be arranged close to the front side of the frame 79 while avoiding the lower frame member 86.

  Next, an installation method (installation method) of the spinning machine 1 of the present embodiment will be described.

  As described above, in the spinning machine 1 of the present embodiment, the drive end box 3 and the machine base body 2 are configured separately. Therefore, when the spinning machine 1 is installed, the drive end box 3 and the machine base body 2 can be carried separately.

  When the spinning machine 1 is installed, first, the machine base body 2 is loaded, and the machine base body 2 is installed at an appropriate position.

  Subsequently, a hole for driving the anchor bolt 107 of the traverse drive unit 32 is formed in the ground 109 at a predetermined position on the side of the machine base body 2. By forming a hole in the ground 109 in advance as described above, the operation of fixing the traverse driving unit 32 to the ground 109 with the anchor bolt 107 can be performed smoothly.

  The traverse rod 62 needs to be connected to the output shaft 93 of the traverse drive unit 32. For this reason, when the traverse driving unit 32 is fixed to the ground 109, the axis of the output shaft 93 and the axis of the traverse rod 62 must match. Therefore, it is necessary to form a hole for driving the anchor bolt 107 into the ground 109 at a precisely positioned position.

  Therefore, when the spinning machine 1 of the present embodiment is installed, a hole for driving the anchor bolt 107 is formed in the ground 109 using a positioning jig 111 as shown in FIG. The positioning jig 111 has an engaging portion 112 that engages with a side portion of the machine base body 2 and a template portion 113. A template hole 114 is previously formed in the template portion 113 at a position where the hole of the anchor bolt 107 is to be formed. As shown in FIG. 11, the positioning jig 111 is used in a state where the engaging portion 112 is engaged with the side portion of the machine base body 2 that has already been installed, and the ground 109 at the position of the template hole 114. A hole for the anchor bolt 107 is formed on the surface. By using the positioning jig 111 in this way, a hole for the anchor bolt 107 can be formed in the ground 109 at an appropriate position with respect to the machine base body 2.

  When the hole for the anchor bolt 107 is formed in the ground 109, the drive end box 3 is subsequently installed on the side of the machine base body 2. As described above, in the spinning machine 1 of the present embodiment, the traverse drive unit 32 is independent of the frame 79 of the drive end box 3. However, if the traverse drive unit 32 and the drive end box 3 have to be carried separately, it is troublesome. Therefore, when the drive end box 3 is carried in, the traverse drive unit 32 is fixed to the frame 79 of the drive end box 3 with a carrying-in bracket 115 as shown by a two-dot chain line in FIG. It is preferable. According to this, since the traverse drive unit 32 can be carried in integrally with the drive end box 3, it is possible to save time and labor at the time of carrying in.

  When the operation of installing the drive end box 3 on the side of the machine base body 2 is completed, the carry-in bracket 115 is removed, and the connection between the frame 79 of the drive end box 3 and the traverse drive unit 32 is released. As a result, the traverse drive unit 32 becomes independent from the frame 79. Subsequently, the anchor bolt 107 is driven into the ground 109 through the insertion hole (not shown) of the fixing plate 106 of the traverse driving unit 32. Thereby, the vibration relief part 105 is formed and the traverse drive part 32 is fixed to the ground 109. Since the hole for driving the anchor bolt 107 into the ground 109 is formed in the ground 109 in advance, the operation of fixing the traverse driving unit 32 to the ground 109 can be performed smoothly.

  As described above, the traverse drive unit 32 is disposed in the frame 79 of the drive end box 3 so as to be close to the frontmost position. For this reason, when forming the vibration relief part 105 on the front side of the traverse driving part 32, the lower frame member 86 becomes obstructive and it is difficult to drive the anchor bolt 107 into the ground 109.

  Therefore, in the spinning machine 1 of the present embodiment, the lower frame member 86 is detachably attached to the frame 79 body of the drive end box 3. That is, when the traverse drive unit 32 is installed, the lower frame member 86 is removed, so that the lower frame member 86 is formed when the vibration relief portion 105 on the front side is formed (when the anchor bolt 107 is driven into the ground 109). Will not get in the way. Therefore, the work of installing the traverse drive unit 32 can be performed smoothly. After the operation of driving the anchor bolt 107 into the ground 109 is completed, the lower frame member 86 is attached to the frame 79 body. Thereby, the rigidity of the frame 79 of the drive end box 3 can be ensured.

  As described above, the spinning machine 1 according to the present embodiment includes the traverse mechanism 60, the traverse drive unit 32, the vibration relief unit 105, and the frame 79. The traverse mechanism 60 is provided over the plurality of spinning units 6 and commonly performs traversing of the spun yarn 15 taken up by each spinning unit 6. The traverse drive unit 32 reciprocates the traverse mechanism 60. The vibration release unit 105 releases vibration generated when the traverse driving unit 32 drives the traverse mechanism 60. The frame 79 accommodates the traverse driving unit 32. The traverse drive unit 32 and the vibration relief unit 105 are provided independently of the frame 79.

  As described above, the traverse drive unit 32 is provided independently of the frame 79, and the vibration relief unit 105 for releasing the vibration of the traverse drive unit 32 other than the frame 79 is provided. 79 can be prevented. As a result, it is possible to prevent the frame 79 from being damaged by the vibration of the traverse drive unit 32. As a result, the durability of the spinning machine 1 is improved.

  The spinning machine 1 according to this embodiment includes an operation unit 18 common to the plurality of spinning units 6 and an air supply unit 34 that supplies air to the plurality of spinning units 6. The operation unit 18 and the air supply unit 34 are attached to the frame 79.

  That is, since the traverse drive unit 32 is provided independently of the frame 79, vibrations of the traverse drive unit 32 can be prevented from being transmitted to the frame 79. Therefore, the operation unit 18 or the air supply unit attached to the frame 79 can be prevented. The vibration is not transmitted to 34. Therefore, the operation unit 18 and the air supply unit 34 can be prevented from being damaged by the vibration of the traverse driving unit 32.

  In the spinning machine 1 of the present embodiment, the vibration relief unit 105 is fixed to the installation surface of the spinning machine 1.

  By fixing the vibration relief portion 105 to the installation surface in this way, the vibration of the traverse driving unit 32 can be released to the installation surface. In addition, as a result of the vibration relief portion 105 being fixed to the installation surface, the traverse drive unit 32 can be reliably fixed to the installation surface. Thereby, the traversing mechanism 60 can stably traverse the yarn, and the high-quality package 17 can be formed.

  In the spinning machine 1 of the present embodiment, the frame 79 includes a lower frame member 86 that constitutes a part of the lower portion of the frame 79. The lower frame member 86 is detachable from the main body of the frame 79.

  Since the lower frame member 86 is detachably provided in this manner, the lower frame member 86 can be removed and the work can be easily performed when the vibration relief portion 105 is fixed to the installation surface. In addition, the rigidity of the frame 79 can be increased by attaching the lower frame member 86 to the frame 79 body after the vibration relief portion 105 is fixed.

  The spinning machine 1 of the present embodiment is configured as follows. That is, the spinning unit 6 includes a yarn supplying unit 9 that supplies the spun yarn 15 and a winding unit 13 that winds the spun yarn 15 traversed by the traverse mechanism 60 around the package 17. The yarn feeding section 9 is arranged at the upper part of the machine base body 2, and the traverse mechanism 60 and the winding part 13 are arranged at the lower part of the machine body.

  Thus, in the case of a layout in which the traverse mechanism 60 is disposed at the lower part of the machine base body 2, the traverse drive unit 32 that is a drive source of the traverse mechanism 60 can be disposed at a low position. Therefore, the traverse driving unit 32 can be firmly fixed to the installation surface.

  The spinning machine 1 of the present embodiment is configured as follows. That is, the traverse mechanism 60 includes a plurality of traverse guides 61 that engage with the spun yarn 15 wound by each spinning unit 6 and a traverse rod 62 to which the plurality of traverse guides 61 are attached. The traverse drive unit 32 includes a cam drum 94, a motor 91 that rotationally drives the cam drum 94, and a cam mechanism that converts the rotational motion of the cam drum 94 into a reciprocating motion and outputs it from the output shaft 93. The output shaft 93 and the traverse rod 62 are connected.

  According to the configuration of the above embodiment, in such a traverse type spinning machine 1, it is possible to prevent vibration from being transmitted to the entire spinning machine 1 and to form the package 17 stably.

  The spinning machine 1 of the present embodiment is configured as follows. That is, the traverse drive unit 32 includes a cam box 90 that functions as an oil storage unit, an oil recovery unit 100, an oil return hole 102, and a cover member 103. The cam box 90 stores oil supplied to the cam mechanism. The oil recovery unit 100 recovers oil attached to the output shaft 93. The oil return hole 102 returns the oil recovered by the oil recovery unit 100 to the cam box 90. The cover member 103 covers the oil return hole 102 and prevents the oil scattered by the cam mechanism from splashing on the oil return hole 102.

  In this manner, by providing the oil recovery unit 100, oil leakage from the output shaft 93 of the traverse drive unit 32 can be reduced. Moreover, since the cover member is provided, it is possible to prevent the oil from splashing into the oil return hole 102, so that the oil from the oil return hole 102 can be smoothly returned to the cam box 90.

  The spinning machine 1 of the present embodiment is configured as follows. That is, the traverse drive unit 32 includes a base body 92, a cam box 90 that houses the cam drum 94 and the cam mechanism, and two suspension support members 104 that support the cam box 90 from the base body 92. The two suspension support members 104 are attached to the base body 92 so as to be symmetric with respect to the center of gravity 90a of the cam box 90.

  By supporting the cam box 90 in this manner, the base body 92 can receive vibration from the cam box 90 uniformly.

  The above spinning machine 1 is configured as follows. That is, the yarn supplying section 9 includes a draft device 10 for drafting the fiber bundle 14 and an air spinning device 41 for producing the spun yarn 15 by twisting the fiber bundle 14 drafted by the draft device 10 with an air flow. Have. The spun yarn 15 supplied from the yarn supplying unit 9 is wound around the package 17 by the spinning unit 6 while traversing the traverse mechanism 60.

  That is, since the pneumatic spinning device 41 can perform spinning at a high speed, the traverse speed of the traverse mechanism 60 is also increased, and the traverse driving unit 32 is likely to generate vibration. Therefore, in the spinning machine 1 equipped with such an air spinning device 41, by adopting the configuration of the present invention, the vibration relief unit 105 prevents the vibration of the traverse drive unit 32 from being transmitted to surrounding equipment. Can be exhibited particularly suitably.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  In the above embodiment, the spun yarn 15 is pulled out from the spinning unit 11 by rotating the yarn accumulating roller 63 of the yarn accumulating device 12. Instead of this, for example, as described in Japanese Patent Application Laid-Open No. 2005-220484, a yarn feeding device that pulls out the spun yarn from the spinning device by sandwiching and rotating the spun yarn between the delivery roller and the nip roller may be provided. good.

  In the above embodiment, the package conveyor 75 is provided between the spinning unit 6 and the doffing cart traveling rail 39, but the spinning unit 6, the doffing cart traveling rail 39, and the package conveyor 75 are arranged in this order. May be. However, a configuration in which the full package 17 is automatically collected by the package conveyor 75 may be omitted. In this case, a package placement portion for temporarily storing the full-package 17 is formed at the position where the package conveyor 75 is arranged in the above embodiment. In this case, the operator manually collects the full-package 17 placed on the package placement unit.

  From the viewpoint of forming the entire configuration of the spinning machine 1 in a compact manner, the layout of the above embodiment in which the traverse driving unit 32 is arranged close to the front side of the drive end box 3 is desirable, but the drive end box 3 The position of the traverse driving unit 32 may be changed as appropriate according to the layout of the other configuration. The traverse drive unit 32 may be fixed to the ground 109 by the vibration release unit 105 so that the vibration of the traverse drive unit 32 is not transmitted to the frame 79.

  Of course, the target for the vibration relief unit 105 to release the vibration of the traverse drive unit 32 is not limited to the ground 109 (installation surface). For example, you may comprise so that the vibration of the traverse drive part 32 may be escaped to the wall surface of the textile factory in which the spinning machine 1 was installed. In short, it is only necessary that the vibration of the traverse driving unit 32 can be released so as not to be transmitted to the frame 79 and the machine base body 2.

  In FIG. 1, the winding unit 13 is illustrated as forming a cone-shaped (tapered) package 17, but a cheese-shaped (cylindrical) package may be formed.

  The configuration of the pneumatic spinning device 41 included in the spinning unit 11 is not limited to that of the above-described embodiment, and may be, for example, a pneumatic spinning device having a pair of air jet nozzles that twist in opposite directions. In addition, the spinning unit 11 is not limited to a configuration in which spinning is performed with an air spinning device, and may be configured to perform spinning with another type of spinning device. However, the configuration of the present invention is not limited to the spinning machine and can be widely applied to other types of yarn winding machines such as an automatic winder.
