Description

  The present invention relates to a spinning machine including various devices such as a draft processing unit, an air spinning unit, and a winding unit.

  This type of spinning machine is known, for example, from Patent Document 1. There, each equipment such as a draft processing unit, an air spinning unit, a delivery roller, and a winding unit is arranged in a straight line along the yarn path from the lower side to the upper side above the can that accommodates the sliver (fiber bundle). A spinning machine.

WO 06/122605 pamphlet (see Fig. 1)

  When each device is arranged along a yarn path extending linearly up and down as in Patent Document 1, the vertical dimension of the spinning machine becomes large, and an operator such as a winding unit arranged on the upper portion of the spinning machine becomes larger. Is out of reach. Therefore, the operator needs to bring the work table from another place when handling or maintaining the equipment on the upper part of the spinning machine. This has led to a decrease in workability of handling and maintenance, and has contributed to a decrease in spinning work efficiency.

  In order to solve this problem, it is easiest to reduce the vertical dimension of the can. However, according to this, the capacity of the can is reduced and the internal sliver is used up quickly. As a result, the number of can replacements increases, and the manufacturing efficiency of the package decreases. Therefore, it is not preferable to reduce the size of the can in order to avoid an increase in the vertical dimension of the spinning machine.

  It is an object of the present invention to review the arrangement pattern of each device constituting the spinning machine so that the handling and maintenance of each device can be easily performed, and thus the spinning that can improve the productivity of the package. Is to provide a machine.

  The spinning machine according to the present invention includes a draft processing unit that stretches a sliver, an air spinning unit that twists the sliver stretched by the draft processing unit and sends the spun yarn, and winds the spun yarn to form a package. It is configured to include each device such as a winding unit. The yarn path in the device arrangement section where each device is arranged is composed of a first yarn path that is inclined horizontally or gently, and a second yarn path that is continuously guided to turn along the first yarn path, Equipment is disposed along the first and second yarn paths. The yarn path according to the present invention as a whole has a shape such as “ku” (“<(inequality sign)”), “L”, or a mirror character thereof. “Slightly tilting” with respect to the first yarn path means tilting up or down at a tilt angle of 45 degrees or less.

  Specifically, a draft processing unit and an air spinning unit are disposed on the first yarn path, and a winding unit is disposed on the downstream end of the second yarn path. A turning guide is disposed between the first yarn path and the second yarn path to guide the direction of the spun yarn to the second yarn path.

  The upstream side of the draft processing unit and the winding unit can be arranged on the passage side of the operator who operates the spinning machine, and the turning guide can be arranged behind the draft processing unit and the winding unit when viewed from the passage. . The position of the turning guide when viewed from the passage may be on a straight line connecting the draft processing unit and the winding unit, or may be a position shifted laterally from the straight line.

  The whole of the first yarn path and the second yarn path can be arranged on the passage side of the operator who operates the spinning machine.

  The turning guide may be configured by at least one of a delivery roller arranged at the downstream end of the first yarn path and a yarn accumulating device arranged at the upstream end of the second yarn path. it can.

  In the spinning machine according to the present invention, the yarn path in the device placement section where each device is placed, the first yarn path that is inclined horizontally or gently, and the second yarn that is continuously guided to the first yarn path. Composed with the road. As a result, the vertical distance from the lower end of the first yarn path to the upper end of the second yarn path can be reduced by nearly 50% compared to the conventional one. The overall vertical dimension can be reduced. Therefore, the operator can easily reach the equipment on the upper part of the spinning machine without using a workbench, and can handle and maintain these equipment easily and accurately. As a result, the working efficiency when operating the spinning machine can be improved, and the productivity of the package as a whole can be improved. Furthermore, according to the present invention, the vertical dimension is reduced as compared with the conventional spinning machine, and the winding unit can be positioned below the conventional spinning machine. As a result, the automatic winder doffing device can be shared. It becomes possible.

  Specifically, a draft processing unit and an air spinning unit are arranged on the first yarn path, and a winding unit is arranged on the downstream end of the second yarn path. In this case, it is possible to easily and accurately carry out removal of the package and replacement of the winding core at the winding portion at the downstream end of the second yarn path.

  If the upstream side of the draft processing unit is disposed on the operator's passage side, the operator can easily perform the work of introducing the sliver to the upstream side. Similarly, when the winding portion is arranged on the passage side, it is possible to easily and accurately perform removal of the package, replacement of the winding core, and the like. That is, according to the present invention, the vertical dimension of the entire spinning machine can be reduced while realizing the arrangement of the equipment desirable for the operator. Also, since the width of the spinning machine as viewed from the passage is smaller than when the entire first yarn path and the second yarn path are arranged on the passage side, more spinning machines are installed along the passage. be able to.

  When the entire first yarn path and the second yarn path are arranged on the passage side of the operator who operates the spinning machine, the operator can easily access all the devices arranged along these yarn paths. be able to. Therefore, the operator can easily handle and maintain these devices. That is, according to the present invention, the vertical dimension of the entire spinning machine can be reduced while realizing the arrangement of the equipment desirable for the operator.

  According to the configuration in which the delivery roller or the yarn accumulating device also serves as a turning guide, the entire configuration of the spinning machine can be simplified by the amount that it is not necessary to provide a dedicated turning guide. In the configuration in which the delivery roller also serves as a turning guide, the tension of the spun yarn can be easily controlled by controlling the driving state of the delivery roller. In the configuration in which the yarn storage device also serves as a turning guide, the tension of the spun yarn stored in the yarn storage device is independent of the bending angle, and the tension is set smaller than the tension of the spun yarn before and after the yarn storage device. Therefore, the spun yarn can be bent largely without imposing a large load on the spun yarn. Further, in a form in which both the delivery roller and the yarn accumulating device also serve as a turning guide, even when the bending angle from the first yarn path to the second yarn path is small, the spun yarn is easily transferred to the second yarn path. it can. That is, if the direction of the spun yarn is changed using two turning guides, the bending angle of the spun yarn in each turning guide can be increased compared to the case where only one turning guide is used. The tension acting on the spun yarn in the direction guide can be significantly reduced. Thereby, since the load applied to the spun yarn is reduced, it is possible to reliably prevent the occurrence of problems such as the spun yarn being cut.

  1 to 3 show an embodiment of a spinning machine according to the present invention. In this embodiment, as shown in FIG. 2, a group of spinning machines 4 are arranged adjacent to the machine base 1 in a straight line. In the present embodiment, for convenience of explanation, the arrangement direction of the group of spinning machines 4 is defined as the left-right direction, and the direction orthogonal to the left-right direction in the horizontal plane is defined as the front-rear direction. Moreover, the direction orthogonal to the floor surface on which the machine base 1 is installed is defined as the vertical direction. Which is the left (front, top) and which is the right (back, bottom) follows the display using the cross arrows in FIGS. 1 and 2.

  A prime mover box 2 is disposed at the left end of the machine base 1, and a blower box 3 is disposed at the right end of the machine base 1. A storage unit 7 in which a can 10 for housing the sliver S is stored is provided at the lower part of the front surface of the machine base 1, and each device constituting the spinning machine 4 is arranged at the upper part of the front surface of the machine base 1. A device arrangement unit 8 is provided. On the front side of the machine base 1, an operator passage runs in the left-right direction. The spinning machine 4 manufactures a package P formed by winding the spun yarn Y from a raw material sliver S, and one can 10 is arranged for each spinning machine 4. The cans 10 are formed in a bottomed cylindrical shape whose upper surface is open, and are the same size as the cans used in conventional spinning machines. The cans 10 may be formed in a rectangular tube shape.

  As shown in FIGS. 1 and 3, the yarn path of the spinning machine 4 in the device placement unit 8 is substantially “く” (“<(inequality sign)”) in both the first yarn path R1 and the second yarn path R2. Construct in a shape. The first yarn path R1 is a horizontal yarn path that is arranged from the lower front side to the lower rear side of the device placement unit 8. The second yarn path R2 is formed of a yarn path that is guided to turn obliquely upward from the lower rear side of the device placement unit 8 toward the upper front side, following the first yarn path R1. Strictly speaking, the first yarn path R1 is not a straight line in the front-rear direction, but is composed of a substantially linear bent line that is continuous in a state of being bent up and down or left and right in the middle. In the second yarn path R2, the yarn path changes in the left-right direction by the traverse width of the traverse drum 28 of the winding unit 17, but the center of the traverse width is regarded as a representative of the yarn path.

  The spinning machine 4 includes various devices such as a sliver guide 11, a draft processing unit 12, an air spinning unit 13, a delivery roller 14, a yarn storage device 15, a yarn clearer 16, and a winding unit 17. Among these devices 11 to 17, the sliver guide 11, the draft processing unit 12, the air spinning unit 13, and the delivery roller 14 are arranged in the order of description along the first yarn path R <b> 1. Further, the yarn accumulating device 15, the yarn clearer 16, and the winding unit 17 are arranged in the order of description along the second yarn path R2.

  The draft processing unit 12 includes four draft roller pairs that sandwich and extend the sliver S. Specifically, a back roller pair 21, a third roller pair 22, a second roller pair 23 around which an apron belt is wound, and a front roller pair 24, each including a pair of upper and lower rollers, are upstream of the first yarn path R1. Are arranged side by side in the front-rear direction. The rotational speeds of the draft roller pairs 21 to 24 increase toward the downstream side. Thus, the sliver S is stretched to a predetermined fineness while being sent to the downstream side based on the ratio of the rotational speeds of the adjacent draft roller pairs while passing through the draft processing unit 12. In the present embodiment, the upstream back roller pair 21 is disposed on the front side of the machine base 1, that is, on the passage side of the operator, so that the operator can easily perform the work of introducing the sliver S into the back roller pair 21. Can be done.

  The air spinning section 13 incorporates an air spinning nozzle that forms a swirling airflow and a hollow guide shaft, and a spun yarn Y is formed by blowing and twisting the swirling airflow onto the sliver S through the cooperative action of both. The spun yarn Y sent from the air spinning unit 13 is guided to turn obliquely upward and forward by the delivery roller 14 and the yarn accumulating device 15, and sent to the second yarn path R2. That is, in this embodiment, both the delivery roller 14 and the yarn accumulating device 15 also serve as a turning guide. The spun yarn Y is bent at an obtuse angle at the delivery roller 14, and is bent at a right angle at the yarn storage device 15. Reference numeral 26 denotes a nip roller that holds the spun yarn Y in cooperation with the delivery roller 14, and the spun yarn Y is fed and operated by both 14 and 26.

  The yarn storage device 15 has a cylindrical shape having a tapered flange on the downstream side of the second yarn path R2. The spun yarn Y is drawn into the yarn storage device 15 in a direction orthogonal to the rotation center axis of the yarn storage device 15, and stored by being wound spirally around the outer peripheral surface thereof. The spun yarn Y in the storage state is drawn out in the direction of the rotation center axis of the yarn storage device 15 and is checked by the yarn clearer 16 for the presence or absence of a yarn defect, and then wound by the winding unit 17.

  The winding unit 17 located at the downstream end of the second yarn path R2 and at the uppermost part of the spinning machine 4 includes a traverse drum 28 for traversing the spun yarn Y in the central axis direction of the package P, and a winding core of the package P. The cradle arm 29 is supported. The cradle arm 29 is urged by a biasing means (not shown) in a direction in which the package P contacts the traverse drum 28. The traverse drum 28 rotates while being in contact with the package P, and applies rotational power to the package P. The winding unit 17 is disposed on the front side of the machine base 1, that is, on the passage side of the operator, so that the operator can take out the package P and replace the winding core easily and accurately.

  As described above, the yarn path of the spinning machine 4 in the device placement unit 8 is bent at an obtuse angle at the delivery roller 14, and is bent at a right angle at the yarn storage device 15. Thus, the bending angle θ from the first yarn path R1 to the second yarn path R2 is an acute angle. The bending angle θ is desirably 90 ° or less in order to reduce the vertical dimension of the device placement portion 8. When the bending angles of the spun yarn Y in the delivery roller 14 and the yarn accumulating device 15 are α and β, respectively, the bending angle θ = α + β−180 ° can be expressed.

  As described above, in the present embodiment, the yarn path of the spinning machine 4 in the device arranging unit 8 is divided into the first yarn path R1 and the first yarn path R1 that are arranged from the lower front side toward the lower rear side. The second yarn path R2 continuously deflected and guided to the upper half of the device placement unit 8 is formed in a square shape. As a result, the vertical distance from the lower end of the first yarn path R1 to the upper end of the second yarn path R2 could be reduced to around 600 mm, which is nearly 50% smaller than the conventional distance. The vertical distance from the floor surface to the winding unit 17 could be about 1800 mm, which is slightly larger than the average operator height. Therefore, the operator can easily reach the winding unit 17 without using a workbench, so that the handling and maintenance of the winding unit 17 can be performed easily and accurately. Further, the removal of the package P and the replacement of the core can be performed easily and accurately. Thereby, the working efficiency when the spinning machine is operated can be improved, and the productivity of the package P can be improved as a whole.

  In the above embodiment, the first yarn path R1 extends from the lower front side to the lower rear side and the second yarn path R2 extends from the lower rear side to the upper front side. For example, the entirety of the first yarn path R1 and the second yarn path R2 can be arranged on the front side of the device arrangement unit 8. In this case, the first yarn path R1 and the second yarn path R2 extend in the left-right direction instead of the front-rear direction. If the entire yarn path is arranged on the front side, that is, the operator's passage side as in this modification, the operator can easily access all the devices 11 to 17 in the device arrangement unit 8. Therefore, the operator can easily handle and maintain these devices 11 to 17.

  Moreover, in the said embodiment, although both the delivery roller 14 and the thread | yarn storage apparatus 15 shall serve as a turning guide, one of both 14 * 15 may be used as a turning guide. In addition to the delivery roller 14 and the yarn accumulating device 15, a dedicated product as a turning guide can be provided. Specifically, only one or a plurality of dedicated products may be used as the turning guide, or one or both of the delivery roller 14 and the yarn storage device 15 may be combined with the dedicated product and used as the turning guide. . Specific examples of the dedicated product include a rotatable roller and a fixedly supported round shaft-shaped guide rod. The delivery roller 14 and the yarn storage device 15 can be omitted. The yarn storage device 15 can also be configured by a slack tube or the like that stores yarn with air. However, in this case, since the yarn accumulating device 15 cannot be used as a turning guide, it is necessary to provide a dedicated product or use the delivery roller 14 as a turning guide.

  As is apparent from FIGS. 1 and 3, the yarn path in the device placement unit 8 does not have to be strictly “<” (“<(inequality sign)”). For example, it may be an “L” character or a character close to it, and may be a mirror character such as “ku (<)” or “L”. The first yarn path R1 does not need to be horizontal, and may be inclined downward or upward. The draft processing unit 12 does not have to be composed of four draft roller pairs, and can be composed of three draft roller pairs. Instead of the traverse drum 28, a traverse guide for traversing the spun yarn Y and a friction roller for contacting the package P and applying rotational power can be provided.
