Description

  The present invention relates to a winder that winds a thread around a bobbin.

  In the winding machine described in Patent Document 1, a contact roller (touch roller) extending in parallel with the bobbin holder is brought into contact with a plurality of bobbins mounted on a cantilevered bobbin holder, whereby the bobbin is contacted by the contact roller. The thread is wound around the bobbin while applying contact pressure to the bobbin.

  Here, in such a winder, as the amount of yarn wound around the bobbin by the contact roller increases, the bobbin holder bends downward toward the tip portion away from the supported portion due to the weight of the yarn. I'll be stuck.

  Therefore, in the winder described in Patent Document 1, the contact pressure of each bobbin is detected, and the pressure applied to the contact roller is changed by extending or retracting the adjusting cylinder according to the detection result. The contact roller is inclined so as to be substantially parallel to the bent bobbin holder. Thereby, the contact pressure on the bobbin by the contact roller is made uniform.

  Hereinafter, preferred embodiments of the present invention will be described.

  FIG. 1 is a front view of the winder according to the present embodiment. FIG. 2A is a view of FIG. 1 viewed from the direction of arrow IIA. FIG. 2B is a view of FIG. 1 viewed from the direction of arrow IIB. FIG. 3A is a view of FIG. 1 viewed from the direction of arrow III. FIG. 3B is a view in which a mounting member 22a and a swing shaft 36 described later are removed from FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. However, in FIG. 1, a part of the machine base 10 of the winder 1 is illustrated by a two-dot chain line, and an inside of a part indicated by the two-dot chain line is illustrated. In FIG. In order to make the positional relationship of each member easy to understand, the position of the attachment member 22a is indicated by a two-dot chain line. In the following description, as shown in the drawings, a front-rear direction, a left-right direction, and a vertical direction that are orthogonal to each other are defined.

  As shown in FIGS. 1 to 4, the winder 1 includes a machine base 10, two bobbin holders 2, a turret table 3, a contact pressure applying mechanism 4, an inclination mechanism 5 and the like provided on the machine base 10. I have.

  The two bobbin holders 2 are substantially cylindrical members, and are cantilevered by the turret table 3. The bobbin holder 2 is provided with a plurality of substantially cylindrical bobbins B. The bobbin holder 2 is driven by a motor (not shown) or the like to rotate around the rotation shaft 2a, whereby the yarn Y is wound around a plurality of bobbins B attached to the bobbin holder 2 as will be described later. Here, a traverse device 7 is provided above each of the plurality of bobbins B attached to the bobbin holder 2, and a yarn guide 8 is provided above each traverse device 7. Thereby, the yarn Y is wound around the bobbin B while being traversed by the traverse device 7 with the yarn guide 8 as a fulcrum. The traverse device 7 and the yarn guide 8 are disposed on a support member 12 described later, and the distance between them is always constant.

  The turret table 3 is a substantially circular plate-like body, supports the two bobbin holders 2 in a cantilever manner as described above, and rotates around a rotation shaft 3 a parallel to the axis of the bobbin holder 2. Thus, the two bobbin holders 2 are moved. Thereby, in the winder 1, the positions of the two bobbin holders 2 can be switched, and while the yarn is being wound on the bobbin B attached to one bobbin holder 2, the other By replacing the bobbin B with the bobbin holder 2, the yarn can be continuously wound. Further, as will be described later, the turret table 3 also rotates with an increase in the amount of yarn Y to be wound up when winding the yarn Y around the bobbin B.

  The contact pressure applying mechanism 4 includes a contact roller 11 and a support member 12. The contact roller 11 extends substantially parallel to the bobbin holder 2, and is in contact with the outer peripheral surface of the bobbin B attached to the bobbin holder 2 at the winding position of the two bobbin holders 2. As a result, contact pressure is applied to the bobbin B by the contact roller 11 when the yarn Y is wound.

  The support member 12 rotatably supports both end portions of the contact roller 11. Further, linear motion bearings 19 are provided in the vicinity of both ends of the support member 12, and guide shafts 13 extending vertically are inserted through the linear motion bearings 19. Here, the support member 12 can be moved up and down by a lifting mechanism (not shown). When the support member 12 is moved up and down, the support member 12 and the contact roller 11 are moved up and down along the guide shaft 13.

  Further, both end portions of the guide shaft 13 are inserted through the linear motion bearings 21a and 21b, respectively. The linear motion bearings 21 a and 21 b are respectively attached to attachment members 22 a and 22 b fixed to the frame 6.

  Further, the inner diameters of the linear motion bearings 21a and 21b are slightly larger than the diameter of the guide shaft 13, and the linear motion bearings 21a and 21b and the guide shaft 13 inserted through the linear motion bearings 21a and 21b. O-rings 23 are interposed between the two. Thereby, the guide shaft 13 can swing with respect to the linear motion bearings 21a and 21b fixed to the frame 6 (attachment members 22a and 22b).

  Next, the configuration of the tilt mechanism 5 will be described. The tilt mechanism 5 is a mechanism for tilting the contact roller 11, and includes a cam 31, a cam rod 32, a booster arm 33, a tie rod 34, a tilt arm 35, and the like.

  Two cams 31 are provided on the side surface of the turret table 3 so as to correspond to the two bobbin holders 2. Each cam 31 extends along the circumferential direction of the turret table 3 as shown in FIG. 2B, and the upstream portion in the clockwise direction in FIG. A certain cam surface 31a projects outward in the radial direction of the turret table 3 with respect to the rotation shaft 3a (at a position away from the rotation shaft 3a of the turret table 3).

  The cam rod 32 has a roller 41 provided at the lower end thereof in contact with the cam surface 31 a and an upper end connected to the booster arm 33. The cam rod 32 includes a rod forming member 32a provided with a roller 41 and a rod forming member 32b connected to the booster arm 33. The two rod forming members 32a and 32b are vertically moved. Relative movement is possible. In addition, a spring 42 is provided between the rod forming member 32a and the rod forming member 32b. When the bolt 43 disposed immediately above the spring 42 of the rod forming member 32b is tightened, the spring 42 is compressed. The Thereby, it is possible to adjust how much the movement of the rod forming member 32a is absorbed by the spring 42 and then transmitted to the rod forming member 32b depending on how much the bolt 43 is tightened. The spring 42 may not be provided. In this case, the portion corresponding to the two rod forming members 32a and 32b of the cam rod 32 may be formed by one member.

  The booster arm 33 is a substantially rectangular plate-like body. A cam rod 32 is attached to one end of the booster arm 33, and an oscillating shaft 36 inserted into a bearing 37 is provided at the end opposite to the cam rod 32. It is attached and can swing around the swing shaft 36.

  An attachment shaft 38 for attaching the tie rod 34 is provided at the lower end portion of the swing shaft 36. Thereby, in the booster arm 33, the tie rod 34 is attached at a position closer to the center of the swing shaft 36 than the cam rod 32. The tie rod 34 is attached between the booster arm 33 and the inclined arm 35, and connects the booster arm 33 and the inclined arm 35.

  The bearing 37 through which the swing shaft 36 is inserted is fixed to a portion of the mounting plate 39 that is bent in a substantially U-shape so as to straddle the tie rod 34 in the front-rear direction, and is located on the front side of the tie rod 34. The plate 39 is fixed to the frame 6 on the opposite side of the bearing 37 with the tie rod 34 interposed therebetween. A portion of the mounting plate 39 fixed to the frame 6 is provided with a swing shaft and a bearing similar to the swing shaft 36 and the bearing 37, and the swing shaft of the mounting shaft 38 is provided on this swing shaft. An end opposite to 36 is attached.

  The inclined arm 35 is a plate-like body extending in the front-rear direction, and is supported at the substantially central portion thereof by a swing shaft 24 provided on the attachment member 22a so as to be swingable. In addition, a tie rod 34 is attached to the rear end portion of the inclined arm 35, and a through hole 35a is formed in the front end portion thereof. The above-described guide shaft 13 is inserted through the through hole 35a.

  Next, the winding operation of the yarn Y in the winding machine 1 will be described. 5 to 9 are views corresponding to FIGS. 2, 4, 3B, and 1 when winding the yarn, respectively.

  In order to wind the yarn Y around the bobbin B in the winder 1, first, the yarn Y generated in a spinning device (not shown) disposed above the winder 1 is hung on the yarn guide 8 and the traverse device 7. Thereafter, the bobbin B is threaded in a state where the support member 12 is raised to a position where the contact roller 11 does not contact the bobbin B attached to the bobbin holder 2 by an elevating mechanism (not shown). After threading the bobbin B, the support member 12 is lowered to bring the contact roller 11 into contact with the bobbin B. In this state, the bobbin holder 2 is rotated to apply a contact pressure to the bobbin B. The yarn Y is wound around the bobbin B.

  Here, when the yarn Y is wound around the bobbin B as described above, the diameter of the bobbin B including the yarn Y gradually increases as the amount of the yarn Y wound up increases. In addition, it is necessary to gradually increase the distance between the bobbin holder 2 and the contact roller 11.

  At this time, in this embodiment, the support member 12 is not moved up and down (the contact roller 11 is held at a predetermined position), and the amount of the yarn Y wound around the bobbin B as shown in FIG. The turret table 3 is rotated in the direction away from the contact roller 11 (counterclockwise direction in FIG. 5A, clockwise direction in FIG. 5B) as 11 is gradually increased.

  When the turret table 3 is thus rotated, the cam 31 provided on the side surface of the turret table 3 is also rotated about the rotation shaft 3a as shown in FIG. As described above, the cam surface 31a of the cam 31 protrudes outward in the radial direction of the turret table 3 with respect to the rotation shaft 3a as the upstream side portion in the clockwise direction in FIG. When the cam 31 rotates, the cam rod 32 that comes into contact with the cam surface 31a of the cam 31 is pushed out by the cam 31 and moves upward as indicated by an arrow a.

  When the cam rod 32 moves, as shown in FIG. 6, the booster arm 33 rotates counterclockwise about the swing shaft 36, and in conjunction with this, the tie rod attached to the booster arm 33. 34 is pulled to the booster arm 33 side (right side in the figure) as indicated by an arrow b. At this time, as described above, since the tie rod 34 is attached to the position closer to the center of the swing shaft 36 than the cam rod 32 in the boost arm 33, the boost arm 33 is moved by the cam rod 32 moving. The amount of movement of the tie rod 34 when is rotated is smaller than the amount of movement of the cam rod 32. Accordingly, the magnitude of the force acting on the tie rod 34 from the booster arm 33 is larger than the magnitude of the force acting on the booster arm 33 from the cam rod 32.

  When the tie rod 34 is pulled toward the booster arm 33, as shown in FIG. 7, the rear end portion of the inclined arm 35 coupled to the tie rod 34 is also pulled toward the booster arm 33 as shown by the arrow b. As a result, the inclined arm 35 rotates clockwise about the swing shaft 24. Then, by the rotation of the inclined arm 35, the front end portion of the inclined arm 35 through which the guide shaft 13 is inserted moves in the direction opposite to the rear end portion (leftward in the drawing) as indicated by an arrow c.

  When the front end portion of the inclined arm 35 moves in this way, as shown in FIGS. 6 and 8, the guide shaft 13 is pushed by the inclined arm 35 (the wall of the through hole 35a) and is inclined. The support member 12 that moves up and down along the guide shaft 13 and the contact roller 11 supported by the support member 12 are inclined. At this time, the contact roller 11 is inclined so that the portion corresponding to the tip side portion of the bobbin holder 2 is positioned downward (in FIG. 8, the inclination angle immediately before the completion of winding is α). .

  That is, in the present embodiment, the turret table 3 is a moving unit according to the present invention, and the tilt mechanism 5 configured by the cam 31, the cam rod 32, the booster arm 33, the tie rod 34, and the tilt arm 35 is It is mechanically linked to the turret table 3. And the inclination mechanism 5 inclines the contact roller 11 using rotation of the turret table 3 as a moving part. Further, as the amount of the yarn Y wound around the bobbin B increases and the turret table 3 rotates largely, the inclination angle of the contact roller 11 increases.

  Here, when the amount of the yarn Y wound on the bobbin B increases, the bobbin holder 2 bends downward toward the tip side away from the portion supported by the turret table 3 due to the weight of the yarn Y. The amount increases as the amount of yarn Y wound around the bobbin B increases. At this time, unlike the case described above, if the contact roller 11 is not inclined, the contact pressure applied by the contact roller 11 becomes smaller in the bobbin B attached to the tip end side of the bobbin holder 2, and as a result, the yarn Y When the winding of the bobbin B is completed, a difference occurs between the left and right diameters of the bobbin B.

  However, in the present embodiment, as described above, as the amount of the yarn Y wound around the bobbin B increases, the contact roller 11 moves downward as the part corresponding to the tip side part of the bobbin holder 2. Since the bobbin holder 2 and the contact roller 11 are held in a substantially parallel state, the distance between them becomes uniform. Thereby, the contact pressure between the contact roller 11 and the bobbin B becomes uniform, and the diameter of the bobbin when the winding is completed becomes uniform.

  Furthermore, in the present embodiment, the tilting mechanism 5 mechanically interlocked with the turret table 3 causes the turret table 3 that rotates in conjunction with the increase in the amount of the yarn Y wound around the bobbin B to rotate. By transmitting to the guide shaft 13, the contact roller 11 is inclined. For this reason, even if any part of the tilt mechanism 5 is damaged, the rotation of the turret table 3 is not transmitted to the guide shaft 13 (the tilt mechanism 5 is mechanically interlocked with the turret table 3). The contact roller 11 cannot be tilted any further, and the contact roller 11 remains held in the posture immediately before the tilt mechanism 5 is broken.

  Therefore, even if the tilt mechanism 5 is broken, the contact roller 11 undergoes a sudden change in the tilt angle, causing the yarn Y to collapse on the bobbin B, or the contact roller 11 to vibrate. It is difficult for the portion supporting the contact roller 11 to be damaged.

  Further, the contact roller 11 is heavy to some extent, and a certain amount of force is required to tilt the contact roller 11. However, as described above, the force acting on the tie rod 34 from the booster arm 33 is as follows. Since the force acting on the booster arm 33 from the cam rod 32 is larger, the heavy contact roller 11 can be inclined even if the force by which the cam 31 pushes the cam rod 32 is not so great.

  Next, modified examples in which various changes are made to the present embodiment will be described. However, the description of the same configuration as the present embodiment will be omitted as appropriate.

  In the above-described embodiment, the rotation of the turret table 3 is transmitted to the guide shaft 13 using the tilt mechanism 5 including the cam 31, the cam rod 32, the booster arm 33, the tie rod 34, and the tilt arm 35. The rotation of the turret table 3 may be transmitted to the guide shaft 13 by another mechanism.

  Further, in the above-described embodiment, the support member 12 and the contact roller 11 are inclined by inclining the guide shaft 13 that supports the support member 12 that supports the contact roller 11 so as to be movable up and down. The contact roller 11 may be directly tilted without tilting the support member 12.

  In the above-described embodiment, since the support member 12 that supports the contact roller 11 can be moved up and down, the contact roller 11 is brought into contact with the bobbin B when the yarn Y is wound, and the yarn is hooked. The contact roller 11 can be separated from the bobbin holder 2, but the configuration for bringing the contact roller 11 into and out of contact with the bobbin holder 2 is not limited thereto.

  In one modification (Modification 1), as shown in FIGS. 9 and 10, a swing shaft 52 is provided on a support member 51 that supports the contact roller 11. Both end portions of the swing shaft 52 are inserted into bearings 53 a and 53 b, respectively, so that the support member 51 can swing about the swing shaft 52. Then, by swinging the support member 51, the contact roller 11 is moved between a position where it abuts on the bobbin B shown by a solid line in FIG. 10 and a position away from the bobbin holder 2 shown by a two-dot chain line in FIG. It can be moved.

  The bearings 53a and 53b are spherical bearings, and the swing shaft 52 can swing with respect to the bearings 53a and 53b.

  The bearing 53 a is attached to a frame (not shown) fixed to the machine base 10, and the bearing 53 b is attached to the arm 54. The arm 54 is supported so as to be swingable around a swing shaft 55 provided at one end thereof, and a bearing 53b is attached to a substantially central portion thereof, and an end opposite to the swing shaft 55 is provided. The cam rod 32 is connected to the portion. That is, in the arm 54, the bearing 53 b is attached at a position closer to the swing shaft 55 than the cam rod 32.

  Also in this case, as in the above-described embodiment, as the amount of the yarn Y wound around the bobbin B increases, the turret table 3 rotates, thereby the cam 31 rotates, The cam rod 32 is pushed out by the cam 31 and moves upward. In the first modification, when the cam rod 32 moves upward, the arm 54 swings around the swing shaft 55 as shown in FIG. Then, the bearing 53b attached to the arm 54 is pushed upward. Accordingly, the swing shaft 52 inserted through the bearings 53a and 53b, the support member 51 supported by the swing shaft 52, and the contact roller 11 supported by the support member 51 are inclined. In this case as well, the contact roller 11 is inclined so that the portion corresponding to the tip side portion of the bobbin holder 2 comes downward. In the first modification, the cam 31, the cam rod 32, and the arm 54 for tilting the contact roller 11 correspond to the tilt mechanism according to the present invention.

  Even in the case of the first modification, since the bearing 53b is attached to the arm 54 at a position closer to the swing shaft 55 than the cam rod 32, the movement amount of the bearing 53b when the arm 54 rotates is small. The moving amount of the cam rod 32 is smaller. Accordingly, the force acting on the bearing 53b from the arm 54 is greater than the force acting on the arm 54 from the cam rod 32, and the heavy contact roller 11 is inclined even if the force by which the cam 31 pushes the cam rod 32 is not so great. Can be made.

  Further, in the above-described embodiment, the distance between the bobbin holder 2 and the contact roller 11 gradually increases as the turret table 3 rotates as the amount of the yarn Y wound around the bobbin B increases. The contact roller 11 is inclined by transmitting the rotation of the turret table 3, but the present invention is not limited to this.

  In another modification (Modification 2), a linear motion bearing 62 is provided at one end of a support member 61 that supports both ends of the contact roller 11, as shown in FIG. Further, the winding machine of the second modification is provided with a guide shaft 63 that is fixed to a frame (not shown) of the machine base 10 and extends vertically, and the linear motion bearing 62 is connected to the guide shaft 63. It is inserted. Accordingly, the support member 61 and the contact roller 11 are supported by the guide shaft 63 and can be moved up and down along the guide shaft 63.

  Here, O-rings 64 are interposed between both end portions of the linear motion bearing 62 and the support member 61, respectively. Thereby, the support member 61 and the contact roller 11 can swing with respect to the guide shaft 63 fixed to the machine base 10.

  A roller 61 a is provided at the end of the support member 61. Furthermore, an inclination mechanism 65 fixed to a frame or the like (not shown) of the machine base 10 is provided on the side of the support member 61 corresponding to the roller 61a.

  The tilt mechanism 65 has a groove 66 extending vertically. A roller 61 a of the support member 61 is fitted in the groove 66, and the roller 61 a moves up and down along the groove 66 as the support member 61 moves up and down along the guide shaft 63. In addition, a guide member 67 that is in contact with the tip of the roller 61a is disposed inside the groove 66. The guide member 67 is inclined with respect to the vertical direction so that the guide surface 67a (guide) that contacts the tip of the roller 61a is closer to the support member 61 (left side in the figure) as the upper part is higher.

  In this case, when the amount of the yarn Y wound around the bobbin B increases, the turret table 3 does not rotate. Instead, the contact roller 11 and the support member 61 cause the yarn Y to be wound up. By being pushed up by the bobbin B whose diameter is increased, the bobbin B moves along the guide shaft 63, whereby the distance between the bobbin holder 2 and the contact roller 11 is increased.

  Then, as the amount of the yarn Y wound around the bobbin B increases, when the contact roller 11 and the support member 61 are pushed up by the bobbin B and moved upward, as shown in FIG. Move upward along 66. Thereby, the roller 61a is guided along the guide surface 67a of the guide member 67, and the support member 61 and the contact roller 11 are inclined. In this case as well, the contact roller 11 is inclined so that the portion corresponding to the tip side portion of the bobbin holder 2 comes downward.

  That is, in the second modification, the contact roller 11 itself corresponds to the moving portion according to the present invention, and the tip end portion of the roller 61a provided on the support member 61 that supports the contact roller 11 is formed by the guide member 67 (guide surface 67a). The contact roller 11 and the tilt mechanism 65 are mechanically interlocked with each other. The tilt mechanism 65 tilts the contact roller 11 using the movement of the contact roller 11 itself when the amount of the yarn Y wound around the bobbin B increases.
