Definitions

  • the present invention relates to a yarn winder configured to wind yarns.
  • Patent Literature 1 Japanese Laid-Open Patent Publication No. 2018-203472 discloses a yarn winder which is configured to wind yarns. As shown in FIG. 10 , this yarn winder 104 includes bobbin holders 124 each of which is cantilevered by the base and extends in a horizontal direction, and plural bobbins B' which are attached to be aligned in an axial direction of each bobbin holder 124.
  • the yarn winder 104 further includes a contact roller 125 configure to apply a contact pressure to plural packages P' formed by winding yarns Y onto the bobbins B.
  • the yarn winder 104 is configured to wind yarns by rotating the bobbin holder 124. As the yarns are wound onto the bobbins B', the diameter of each package P is increased.
  • Patent Literature 2 recites a yarn winder provided with a shielding panel which extends in parallel to a direction, in which a winding spindle (bobbin holder) protrudes, and which is provided in a circumferential direction of a reel (package) formed by winding yarns onto a reel pipe (bobbin) attached to the winding spindle.
  • a winding spindle bobbin holder
  • a reel packet
  • an air guiding panel which extends along the circumferential direction of the reel is provided.
  • Patent Literature 2 an accompanied flow caused by a rotating reel is separated by an air guiding panel included in a shielding panel, and guided in a circumferential direction of the reel. That is, in a yarn winder of Patent Literature 2, the shielding panel is provided in an area located on the downstream side in a reel rotating direction. Therefore, in the yarn winder of Patent Literature 2, separation of an accompanied flow from the outer circumferential surface of the package cannot be suppressed. In this regard, the accompanied flow flows toward the contact point between a package (reel) and a pressing roller. Especially, as the diameter of the package and the area of the outer circumferential surface of the package are increased in accordance with yarn winding, air separated from the outer circumferential surface of the rotating package is also increased. Because of this, air resistance applied to the package is increased so that power consumption is further increased.
  • An object of the present invention is to suppress increase in air resistance due to increase in diameter of a package in accordance with winding of yarns in a yarn winder including a bobbin holder to which plural bobbins are attached and to reduce power consumption.
  • a yarn winder includes: a base; a bobbin holder which is rotatably supported by the base, which extends along an axial direction which is along the horizontal direction, and to which bobbins, which are capable of respectively winding yarns, are attached to be aligned in the axial direction; a contact roller which extends in the axial direction and which makes contact with outer circumferential surfaces of packages formed by winding the yarns onto the respective bobbins; and a first cover member which is provided in at least a part of an area provided upstream of a contact point in a rotational direction of each of the packages and which is provided along a circumferential direction of each of the packages, and the contact point being between the packages and the contact roller.
  • an accompanied flow is guided to the inner circumferential surface of the first cover member so as to flow along the outer circumferential surfaces of the packages toward the contact point. It is therefore possible to suppress the separation of air from the outer circumferential surfaces of the rotating packages. Because of this, the air resistance applied to the packages is suppressed at the time of winding of yarns, and hence the power consumption is reduced.
  • the yarn winder of the first aspect is arranged such that at least a part of the first cover member is provided in an area surrounding lower halves in the vertical direction of entire circumferences of the packages.
  • the yarn winder of the second aspect is arranged such that the first cover member is provided along the circumferential direction to cover a range of up to 225 degrees from the contact point.
  • the first cover member When the first cover member is provided to cover a wide range on the entire circumference of each of the packages, the weight of the entire yarn winder is increased. As a result, the yarn winder easily swings at the time of the winding of yarns. With this, the quality of packages may be deteriorated.
  • the first cover member because the first cover member is provided along the circumferential direction of each of the packages to cover the range of up to 225 degrees from the contact point in the area provided upstream of the contact point in the rotational direction of each of the packages, increase in the weight of the yarn winder is suppressed while the separation of the accompanied flow flowing toward the contact point is suppressed. It is therefore possible to ensure the quality of packages while the power consumption is reduced.
  • the yarn winder of the second or third aspect is arranged such that the first cover member is provided in the area surrounding the lower halves in the vertical direction of the entire circumferences of the packages.
  • the first cover member may be warped downward by gravity, due to the vibration of the rotating packages.
  • the first cover member When the first cover member is provided in the area provided above the upper half surfaces, in the vertical direction, of the entire circumferences of the packages, the first cover member warped downward may make contact with the packages.
  • the first cover member warped downward when the first cover member is provided in the area surrounding the lower halves in the vertical direction of the entire circumferences of the packages, the first cover member warped downward does not make contact with the packages. Because of this, the quality of packages is further ensured.
  • the yarn winder further includes a second cover member which is provided upstream of the contact point in the rotational direction and provided downstream of the first cover member in the rotational direction, the second cover member guiding air, which flows toward the contact point in accordance with rotation of the packages, to gaps between the adjacent packages (P).
  • the accompanied flow flowing toward the contact point is guided to the gaps between the adjacent packages while avoiding separation from the outer circumferential surfaces of the packages.
  • the separation of the accompanied flow from the outer circumferential surfaces of the packages is caused due to the collision with the contact roller. It is therefore possible to further suppress the separation of the air from the outer circumferential surfaces of the rotating packages, and hence the power consumption is further reduced.
  • the yarn winder of anyone of the first to fourth aspect is arranged such that the second cover member is a flat plate provided to cover a range of up to 25 degrees from a tangent which passes the contact point and is centered at the contact point.
  • the accompanied flow flowing toward the contact point is further certainly guided to the gaps between the adjacent packages, and hence the power consumption is further reduced.
  • the yarn winder of anyone of the first to fourth aspect is arranged such that the second cover member is provided along the circumferential direction of each of the packages.
  • an amount of the accompanied flow which flows toward the contact point and which is sent to the gaps between adjacent packages is increased, and hence the power consumption is further reduced.
  • the yarn winder of any one of the first to sixth aspects is arranged such that the first cover member is provided along the circumferential direction to cover a range of 90 degrees or more.
  • the first cover member protects a wide range on the outer circumferential surfaces of the packages, the separation of the air from the outer circumferential surfaces of the rotating packages is further suppressed. As a result, the power consumption is further reduced.
  • the yarn winder of any one of the first to seventh aspects is arranged such that the diameter of the first cover member is variable along the outer circumferential surfaces of the packages in each of which the diameter is increased in accordance with winding of yarns.
  • the separation of the accompanied flow from the outer circumferential surfaces of the packages is suppressed from the start of the winding of yarns, and hence the power consumption is further reduced.
  • the yarn winder of any one of the first to eighth aspects is arranged such that the first cover member and the second cover member extend along the axial direction and cover all of the gaps between the adjacent packages.
  • the first cover member and the second cover member are provided along the axial direction without gaps. Because of this, it is possible to prevent the accompanied flow from passing through the gaps provided along the axial direction and being separated radially outward from the outer circumferential surfaces of the packages. It is therefore possible to further suppress the separation of the accompanied flow from the outer circumferential surfaces of the packages, and hence the power consumption is further reduced.
  • the yarn winder of the nineth aspect is arranged such that both ends of each of the first cover member and the second cover member in the axial direction are provided outside outer ends of the outermost packages in the axial direction.
  • the accompanied flow is prevented from being separated outward in the axial direction from the outer circumferential surfaces of packages provided at the both ends in the axial direction of the rotating packages. Because of this, the power consumption is further reduced.
  • the yarn winder of any one of the first to tenth aspects further includes a movement mechanism configured to cause the first cover member and the second cover member to retreat from a movement trace along which the bobbin holder moves between a yarn winding position and a standby position, and the bobbin holder being movable between the yarn winding position where the winding of yarns is performed and the standby position where the winding of yarns is not performed.
  • the position of the bobbin holder at the yarn winding position and the position of the bobbin holder at the standby position are switched from one another each time the winding of yarns onto the bobbins attached to the bobbin holder is completed.
  • the first cover member and the second cover member to retreat from the movement trace, switching of the positions of the bobbin holders is smoothly performed.
  • the yarn winder of the eleventh aspect is arranged such that the first cover member and the second cover member are formed to be independent from one another.
  • first cover member and the second cover member are formed to be independent from one another as described in the present invention, a space required to move the first cover member and the second cover member away from the movement trace is small as compared to cases where the first cover member and the second cover member are integrally formed. Because of this, increase in size of the entire yarn winder is suppressed.
  • the yarn winder of any one of the first to eleventh aspects is arranged such that the first cover member and the second cover member are integrally formed.
  • the accompanied flow is prevented from passing through the gap between the first cover member and the second cover member and from being separated from the outer circumferential surfaces of the packages. As a result, the air resistance is further decreased. Because of this, the power consumption is further reduced.
