Definitions

  • the present invention relates to a cradle adapted to hold a winding tube.
  • Patent Document 1 discloses a yarn winding machine including this type of cradle.
  • the yarn winding machine of Patent Document 1 includes a motor in proximity to one of the bobbin holding sections (bobbin holders) for driving the winding tube.
  • the bobbin holding section is mounted to a driving shaft of the motor so as to integrally rotate with the driving shaft.
  • the yarn winding machine of Patent Document 1 realizes a method of directly driving the winding tube (direct drive method).
  • the bobbin holding section is configured by a member adapted to be mounted to the driving shaft of the motor (a base member), and a member adapted to make contact with the inner surface of the winding tube (a contact member) .
  • the base member is usually made from metal.
  • the contact member is made from a material having a high friction coefficient (urethane, rubber, or the like) to prevent slipping between the contact member and the winding tube. The contact member is abraded when scraped against the winding tube, for example.
  • the detailed structure of the bobbin holding section is not disclosed in Patent Document 1, but conventionally, a bobbin holding section having a structure in which the base member and the contact member are securely attached so as not to be detachable is known.
  • this type of bobbin holding section when the contact member is abraded, the entire bobbin holding section is required to be replaced even if replacement of the base member is not necessary. A cost in replacing the contact member thus becomes high.
  • An obj ect of the present invention is to provide a cradle having a structure in which a cost and work load in replacing the bobbin holding section are reduced.
  • a cradle includes a cradle main body, a winding tube holding section, and a rotation preventing section.
  • the winding tube holding section is rotatably mounted on the cradle main body and adapted to hold a winding tube around which a yarn is wound.
  • the winding tube holding section includes a base member and a contact member.
  • the base member is rotatably mounted on the cradle main body.
  • the contact member is detachably mounted to the base member by at least a portion of the contact member being elastically deformed, and adapted to hold the winding tube by making contact with the winding tube.
  • the rotation preventing section is adapted to prevent relative rotation of the contact member with respect to the base member.
  • the base member and the contact member are detachable, when the contact member is scraped with the winding tube, or the like and abraded, only the contact member can be replaced instead of the entire winding tube holding section.
  • an operator can detach the relevant contact member by merely elastically deforming the contact member (e.g., without detaching a bolt or the like). Therefore, a work load in replacing the contact member can be reduced.
  • the rotation preventing section includes a protrusion and a receiving section.
  • the protrusion is formed on at least one of the base member and the contact member.
  • the receiving section is formed on at least one of the base member and the contact member and adapted to receive the protrusion.
  • the protrusion is provided on the base member and is a portion of a mounting tool adapted to mount the base member to the cradle main body.
  • the receiving section is formed on the contact member.
  • the mounting tool adapted to mount the base member to the cradle main body also serves as the protrusion, a special protrusion may not be formed on the base member. Therefore, a manufacturing cost of the base member can be reduced. Since the mounting tool is not required to be detached when replacing the contact member, the work load in replacing the contact member can be reduced.
  • an area of a side of the contact member, the side being adapted to make contact with the base member is preferably smaller than an area of a side of the base member, the side being adapted to make contact with the contact member. Accordingly, by elastically deforming the contact member and mounting the contact member to the base member, the base member can reliably hold the contact member.
  • the contact member is preferably urethane. Accordingly, the cradle can have an abrasion resistance property to a certain extent while suppressing slipping between the contact member and the winding tube.
  • the above cradle preferably includes a winding tube driving section adapted to rotationally drive the winding tube by rotating the base member.
  • a winding tube driving section adapted to rotationally drive the winding tube by rotating the base member.
  • a winding unit includes a yarn supplying section and a winding section.
  • the yarn supplying section is adapted to supply a yarn.
  • the winding section includes the cradle, and is adapted to form a package by winding the yarn supplied by the yarn supplying section..
  • the winding unit having a configuration in which the work load in replacing the contact member is reduced can be realized. Therefore, since the contact member can be easily replaced according to the abrasion of the contact member, the slip between the winding tube and the contact member can be suppressed by the winding unit while appropriately replacing the contact member to form a high quality package.
  • a yarn winding machine includes a plurality of winding units. Therefore, in the yarn winding machine, the work load in replacing the contact member can be reduced. In the yarn winding machine including the plurality of winding units, if the work load in replacing the contact member can be reduced, a time during which the winding unit is not winding the yarn due to the replacement of the contact member can be reduced. As a result, winding efficiency of the yarn for the entire yarn winding machine can be improved.
  • Embodiments of the invention will be hereinafter described.

  • the automatic doffing device 8 travels to a position of the relevant winder unit 10 to collect the fully wound package 30 and supply a winding bobbin (empty winding bobbin) 22 around which the yarn 20 is not wound.

  • a package driving motor (winding tube driving section) 41 such as a servo motor is provided on the cradle 23.
  • the winding section 17 rotatably drives the winding bobbin 22 with the package driving motor 41 to wind the yarn 20 around a surface of the winding bobbin 22 (or the surface of package 30) .
  • a driving shaft 41a of the package driving motor 41 is coupled to the winding bobbin 22 so as to be relatively non-rotatable via a larger-diameter side bobbin holding section 43 and the like (so-called direct drive method).

  • the rotation output member is located closer to the winding bobbin 22 than the supporting flange 63.
  • the base member 70 is mounted to the rotation output member in a relatively non-rotatable manner. When mounting the base member 70 to the rotation output member, the operator first inserts the driving shaft 41a to the driving shaft inserting hole 73. The operator then aligns a hole formed in the rotation output member and the bolt inserting hole 72, and inserts and tightens a bolt 68 to fix the base member 70 (see FIG. 5 ).

  • the larger-diameter side bobbin holding section 43 integrally rotates with the driving shaft 41a and can hold the winding bobbin 22. Since the contact member 80 is abraded by the scraping with the winding bobbin 22, or the like, the contact member 80 is required to be replaced at a certain frequency. If the contact member 80 is not replaced, slip easily occurs between the contact member 80 and the winding bobbin 22. When slip occurs, the rotation speed of the driving shaft 41a and the rotation speed of the winding bobbin 22 do not match, and the yarn 20 cannot be wound as controlled by the unit control section 50.
  • a bobbin holding section having a configuration in which the base member and the contact member are non--detachably provided. Since this type of bobbin holding section requires the entire bobbin holding section to be replaced when the contact member is abraded, the cost at the time of replacement is increased. In the present embodiment, since the contact member 80 can be detached from the base member 70, only the contact member 80 can be replaced. Therefore, the cost in replacing the contact member 80 can be reduced.
  • the base member and the contact member are detachably mounted, for example, if the base member and the contact member are detachably mounted by attaching and detaching the bolt or the like, a work load is caused in replacing the contact member.
  • the contact member 80 With a one-touch operation of merely having the operator grip and pull the end of the contact member 80, the contact member 80 can be elastically deformed and detached from the base member 70. As a result, the work load in replacing the contact member 80 can be reduced.
  • the cradle 23 of the present embodiment includes the cradle main body 60, the larger-diameter side bobbin holding section 43, and the rotation preventing section.
  • the larger-diameter side bobbin holding section 43 is rotatably mounted to the cradle main body 60 and adapted to hold the winding bobbin 22 around which the yarn 20 is wound.

  • the contact member 80 is detachably mounted to the base member 70 by at least a portion of the contact member 80 being elastically deformed, and adapted to hold the winding bobbin 22 by making contact with the winding bobbin 22.
  • the rotation preventing section is adapted to prevent relative rotation of the contact member 80 with respect to the base member 70.
  • the rotation preventing section includes the head 68a provided on the base member 70 and the rotation preventing hole 82 formed in the contact member 80.
  • the head 68a is fitted into the rotation preventing hole 82. Accordingly, the relative rotation of the base member 70 and the contact member 80 can be prevented using the bolt 68, and a protrusion is not required to be specially formed on the base member 70. Therefore, the manufacturing cost of the base member 70 can be reduced.
  • an area of a side of the contact member 80 (area of the inner peripheral surface of the contact member 80), the side being adapted to make contact with the base member 70, is smaller than an area of a side of the base member 70 (area of the outer peripheral surface of the base member 70), the side being adapted to make contact with the contact member 80. Accordingly, the contact member 80 is elastically deformed to be mounted on the base member 70, and the base member 70 can reliably hold the contact member 80.
  • the contact member 80 is urethane. Therefore, an abrasion resistance property to a certain extent is provided to the cradle 23 while suppressing the slip between the contact member 80 and the winding bobbin 22.
  • the cradle 23 of the present embodiment includes the package driving motor 41.
  • the package driving motor 41 rotationally drives the winding bobbin 22 by rotating the base member 70.
  • the contact member 80 which is easy to replace, is preferably replaced at a certain frequency.
  • the rotation preventing section is not limited to the structure described above.
  • a protrusion may be formed on the base member 70 in place of the head 68a.
  • a receiving section may be formed on the base member 70, and a protrusion may be formed on the contact member 80.
  • a protrusion and a receiving section may be formed on the base member 70, and a receiving section and a protrusion corresponding to such protrusion and receiving section may be formed on the contact member 80.
  • the receiving section may be a through type (a hole) like the rotation preventing hole 82, or may be a non-through type (a recess).
  • the contact member 80 is not limited to urethane as long as the contact member 80 can hold the winding bobbin 22 without slipping, and may be rubber.
  • the winder unit 10 winds a general cone winding package.
  • the winder unit 10 may wind a package of which an end surface is tapered, or a cheese-shaped package, for example.
  • the traverse device 27 may be a belt-type traverse device adapted to reciprocate the traverse guide in a winding width direction of the package by belt drive, a rotary-type traverse device using a rotary blade, or a rod-type traverse device adapted to reciprocate a rod to which the traverse guide is attached.
  • the traverse device 27 is not limited to a configuration of reciprocating the traverse guide 28 within a substantially horizontal plane with respect to an installation surface of the winder unit 10.
  • a longitudinal direction of the traverse arm may be substantially perpendicular to the installation surface of the winder unit 10.
  • the package driving motor 41 is not limited to a servo motor, and may be various types of motors such as a step motor or an induction motor.
  • the contact roller 29 may be driven with an appropriate driving device and the package 30 may be rotated accompanying the rotation of the contact roller 29.
  • the unit control section 50 controls the package driving motor 41, but a control section dedicated to control the package driving motor 41 may be arranged in the winder unit 10.
  • the present invention is not limited to the automatic winder, and can be applied to other yarn winding machines such as a rewinding machine, a fine spinning machine (e.g., an air-jet spinning machine, an open--end spinning machine), and the like.
  • a rewinding machine e.g., a rewinding machine, a fine spinning machine (e.g., an air-jet spinning machine, an open--end spinning machine), and the like.
