Definitions

  • the present invention relates to a spun yarn take-up machine configured to take up a yarn spun out from a spinning apparatus and to wind the yarn onto a bobbin.
  • Patent Literature 1 Tokuhyou 2013-542898 (Published Japanese Translation of PCT Application) describes an apparatus configured to wind up a yarn onto a spool housing (equivalent to a "bobbin" in the present invention) attached to a spindle while traversing the yarn by a traversing device.
  • the apparatus of Patent Literature 1 is structured as follows. To enable the spindle to catch a yarn at the start of winding of the yarn onto the spool housing, the yarn is moved by an auxiliary device to a position outside the traversing device. After the yarn is caught by the spindle, the yarn is captured by a traverse wing of the traversing device.
  • the auxiliary device includes a metal guide.
  • the metal guide is moved by a first driving unit in a direction along the axial direction of the spool housing, between a parking position adjacent to the traversing device and a receiving position within the region of the traversing device.
  • the metal guide is moved by a second driving unit in a direction crossing the axial direction of the spool housing, between a catching position and a releasing position.
  • the metal guide of the auxiliary device is moved from the parking position to the receiving position while the yarn is traversed by the traversing device.
  • the traversed yarn enters a guide groove of the metal guide, to be caught by the metal guide.
  • the metal guide is moved to the catching position, and then the metal guide is returned to the parking position.
  • Patent Literature 1 the direction in which the metal guide is moved from the catching position to the releasing position is along the depth direction of the guide groove. For this reason, in order to move the metal guide from the catching position to the releasing position so that the yarn slides out of the guide groove as described above, the metal guide has to be moved a long distance to some degree. That is to say, in the arrangement of Patent Literature 1, the moving distance of the metal guide needed to disengage the yarn from the guide groove is long.
  • the yarn is able to be released from the yarn catch guide by moving the yarn catch guide to the yarn releasing position. While the groove portion of the yarn catch guide extends in the first direction, the yarn releasing position is located farther from the traverse guide than the catching position and the yarn shifting position in the second direction orthogonal to both the axial direction of the bobbin and the first direction. Because of this, the yarn is able to be released from the yarn catch guide without distancing the yarn releasing position so far from the traverse guide. Thus, the moving distance of the yarn catch guide needed to release the yarn from the yarn catch guide is shorter than the case where the yarn is released from the yarn catch guide by moving the yarn catch guide in the first direction. Furthermore, in this aspect of the present invention, there is no need to move the yarn catch guide a long distance in the first direction when the yarn is released from the yarn catch guide. This enables downsizing of the machine in the first direction.
  • the spun yarn take-up machine of the first aspect is arranged such that the guide moving device includes: a driving unit configured to apply a force to the yarn catch guide in the axial direction of the bobbin; a first guide unit configured to guide, in parallel to the axial direction of the bobbin, the yarn catch guide moving from the catching position to the yarn shifting position; and a second guide unit configured to guide, in the second direction, the yarn catch guide moving from the yarn shifting position toward the catching position so that the yarn catch guide passes through the yarn releasing position.
  • the guide moving device includes: a driving unit configured to apply a force to the yarn catch guide in the axial direction of the bobbin; a first guide unit configured to guide, in parallel to the axial direction of the bobbin, the yarn catch guide moving from the catching position to the yarn shifting position; and a second guide unit configured to guide, in the second direction, the yarn catch guide moving from the yarn shifting position toward the catching position so that the yarn catch guide passes through the yarn releasing position.
  • Patent Literature 1 for example, two driving units are separately provided. Specifically, the drive unit configured to move the metal guide in the direction along the axial direction of the spool housing between the parking position and the receiving position, and the driving unit configured to move the metal guide in the direction crossing the axial direction of the spool housing between the catching position and the releasing position are provided.
  • the first guide unit and the second guide unit are provided, and this enables the yarn catch guide to be moved in the axial direction of the bobbin and in the second direction by the single driving unit configured to apply a force in the axial direction of the bobbin to the yarn catch guide.
  • the machine has a simpler structure than in the case where a driving unit for moving the yarn catch guide in the axial direction of the bobbin and a driving unit for moving the yarn catch guide in the second direction are provided individually.
  • the spun yarn take-up machine of the second aspect is arranged such that: the yarn catch guide is supported so as to be movable in the axial direction of the bobbin, and so as to be swingable with respect to a swing axis parallel to the axial direction of the bobbin; and the second guide unit guides the yarn catch guide moving from the yarn shifting position toward the catching position so that the yarn catch guide is swung with respect to the swing axis.
  • the yarn catch guide is movable in the second direction by swinging the yarn catch guide with respect to the swing axis parallel to the axial direction of the bobbin.
  • the spun yarn take-up machine of the second or third aspect is arranged such that: the yarn catch guide includes a guided portion guided by the first guide unit and the second guide unit; the first guide unit includes a first guide passage extending in parallel to the axial direction of the bobbin and configured to guide the guided portion; and the second guide unit includes a second guide passage disposed on one side in the second direction relative to the first guide passage and connected with two connection portions of the first guide passage which are apart from each other in the axial direction of the bobbin, the second guide passage being configured to guide the guided portion.
  • the guided portion when the yarn catch guide is moved from the catching position to the yarn shifting position, the guided portion is guided along the first guide passage extending in parallel to the axial direction of the bobbin. Due to this, the yarn catch guide is parallel translated in the axial direction of the bobbin. Meanwhile, when the yarn catching guide is moved from the yarn shifting position toward the catching position, the guided portion is guided along the second guide passage disposed on the one side in the second direction relative to the first guide passage. Due to this, the yarn catch guide is swing to be moved to the yarn releasing position.
  • the spun yarn take-up machine of the fourth aspect is arranged such that: a divider is provided at one of the connection portions of the first guide passage which are connected with the second guide passage, the one of the connecting portions being closer to the yarn shifting position than the other, the divider partitioning the first guide passage in the axial direction of the bobbin; the divider is cantilevered and is therefore elastically deformable; and elastic deformation of the divider toward the yarn shifting position in the axial direction of the bobbin is allowed and elastic deformation of the divider toward the catching position in the axial direction of the bobbin is restricted.
  • the guided portion when the guided portion moves from a position closer to the catching position toward the yarn shifting position in the first guide passage, the guided portion passes through the portion of the first guide passage where the divider is disposed, by elastically deforming the divider.
  • This enables the guided portion to be guided along the first guide passage when the yarn catch guide is moved from the catching position to the yarn shifting position.
  • the guided portion when the guided portion moves from a position closer to the yarn shifting position toward the catching position in the first guide passage, the guided portion cannot elastically deform the divider, and therefore cannot pass through the portion of the first guide passage where the divider is disposed. This prevents the guided portion from being guided along the first guide passage instead of the second guide passage, when the yarn catch guide is moved from the yarn shifting position toward the catching position.
  • the spun yarn take-up machine of the fifth aspect is arranged such that the divider is inclined with respect to the second direction so that a distance between the divider and the yarn shifting position in the axial direction of the bobbin decreases toward a free end of the divider.
  • the cantilevered divider is inclined with respect to the second direction so that the distance between the divider and the yarn shifting position in the axial direction of the bobbin decreases toward the free end of the divider. Because of this, it is easier for the divider to be elastically deformed toward the yarn shifting position, but it is difficult for the divider to be elastically deformed toward the catching position. In other words, elastic deformation of the divider toward the yarn shifting position is allowed, but elastic deformation of the divider toward the catching position is restricted. Furthermore, in this aspect of the present invention, when the yarn catch guide is moved from the yarn shifting position toward the catching position, the guided portion is guided along the inclined divider into the second guide passage.
  • the spun yarn take-up machine of the fifth or sixth aspect is arranged such that a regulatory portion is provided in the first guide passage, the regulatory portion being configured to restrict the elastic deformation of the divider toward the catching position in the axial direction of the bobbin by contacting the divider.
  • the regulatory portion is provided in the first guide passage.
  • the spun yarn take-up machine of any one of the fifth to seventh aspect is arranged such that the guide moving device includes: a first member in which the first guide passage and the second guide passage are disposed; and a second member in which the divider is disposed, the second member attached to the first member so as to be detachable from the first member.
  • the divider is elastically deformed as a result of contact with the guided portion. Because of this, the divider is more likely to wear down and/or to suffer damage. If the divider wears down and/or suffers damage, part replacement is needed.
  • the divider is disposed in the second member, which is different from the first member in which the first guide passage and the second guide passage are disposed, and the second member is detachably attached to the first member. Because of this arrangement, it is only required to replace the second member in the above situation. Thus, the running cost of the spun yarn take-up machine is reducible.
  • the spun yarn take-up machine of the fourth aspect is arranged such that the guide moving device includes: a main body portion supporting the yarn catch guide so as to be movable in the axial direction of the bobbin; a moving member provided at a central portion of the first guide passage in the axial direction of the bobbin and supported by the main body portion so as to be movable in the first direction, the moving member being configured so that the guided portion is able to contact the moving member from one side in the first direction; and a biasing member biasing the moving member from an other side in the first direction to the one side in the first direction.
  • the moving member includes a protruding portion protruding in the first direction and provided between the two connecting portions of the first guide passage which are connected with the second guide passage.
  • An end face of the protruding portion that is on the other side in the axial direction of the bobbin forms a guide surface configured to guide the guided portion into the second guide passage.
  • the moving member when the yarn catch guide is moved from the catching position to the yarn shifting position, the moving member is pressed by the guided portion moving along the surface of the protruding portion in the first direction (e.g., the inclined surface). As a result, the moving member is moved toward the other side in the first direction against the biasing force of the biasing member. After the guided portion passes over the protruding portion, the moving member is moved by the biasing force of the biasing member to the one side in the first direction, to be returned to its original position.
  • the yarn catch guide is parallel translated in the axial direction of the bobbin.
  • the guided portion is guided by the guide surface, into the second guide passage. As the guided portion is guided along the second guide passage, the yarn catch guide is moved to the yarn releasing position.
  • the spun yarn take-up machine of the ninth aspect is arranged such that a deviation preventing portion is provided to the protruding portion, the deviation preventing portion being configured to prevent the guided portion moving along the surface of the protruding portion from moving in the second direction.
  • the above arrangement in this aspect of the present invention prevents the guided portion from moving in the second direction, during the movement along the surface of the protruding portion, and from entering the second guide passage.
  • the spun yarn take-up machine of the tenth aspect is arranged such that: the guided portion has, at an end portion thereof, a groove extending in the axial direction of the bobbin; and the deviation preventing portion is a projection provided on the surface of the protruding portion, extending in the axial direction of the bobbin, and being fittable in the groove.
  • the guided portion has the groove at its end portion, and the protruding portion has, on its surface, the projection fittable in the groove. This arrangement prevents the guided portion from moving in the second direction during the movement along the surface of the protruding portion and entering into the second guide passage.
  • the yarn is able to be released from the yarn catch guide by moving the yarn catch guide to the yarn releasing position. While the groove portion of the yarn catch guide extends in the first direction, the yarn releasing position is located farther from the traverse guide than the catching position and the yarn shifting position in the second direction orthogonal to both the axial direction of the bobbin and the first direction. Because of this, the yarn is able to be released from the yarn catch guide without distancing the yarn releasing position so far from the traverse guide. Thus, the moving distance of the yarn catch guide needed to release the yarn from the yarn catch guide is shorter than the case where the yarn is released from the yarn catch guide by moving the yarn catch guide in the first direction.
  • a spun yarn take-up machine 1 is configured to take up yarns Y spun out from a spinning apparatus 2 and to form packages P by winding the yarns Y onto bobbins B, respectively.

Meanwhile, in this modification, it is only required to replace the cam member 103 including the divider 64, out of the components of the guide member 101. That is, there is no need to replace the main body 102. Thus, in this modification, the running cost of the spun yarn take-up machine is reducible.
