Definitions

  • the present invention relates to an apparatus of a bobbin changing type for winding a yarn, such as a synthetic yarn, at a high speed.
  • the present invention relates to a yarn winding apparatus of an automatic bobbin changing type, which is provided with a plurality of bobbin holders, and in which when a package wound on one of the bobbin holders becomes a predetermined amount, winding of the yarn is changed to another bobbin holder.
  • bobbin winding apparatus of a turret type have been widely used, wherein a turret table formed in a circular disc is supported turnably about a central axis of the disc, and a plurality of bobbin holders are rotatably mounted on the equidistantly spaced positions on the turret table so that yarn winding onto a bobbin holder to another bobbin holder is changed by turning the turret table together with the bobbin holders.
  • the distance between the bobbin holders is required to be at least a distance D, which is obtained by adding a clearance C between an empty bobbin and a full package to a half of sum of a diameter D0 of an empty bobbin and a diameter D f of a fully wound yarn package, i.e., D must be equal to or larger than C+(D0+D f )/2 .
  • D the size, i.e., both the height and the width, of the winding apparatus become large.
  • the contact roller becomes free from driving force during turret operation until an empty bobbin, which have stood by, becomes in contact with the contact roller after a package, onto which a yarn has been wound, goes away from the contact roller.
  • the contact roller is free for about 3 minutes.
  • the rotational speed of the contact roller decreases during the turret operation, and the yarn my be slack and may be broken.
  • the rotational speed of the contact roller does not completely recover its original speed even when a bobbin holder with empty bobbin becomes in contact with the contact roller.
  • a yarn caught by the empty bobbin may be slack and may be broken, and the quality in a yarn at a transfer tail portion or at an inner portion of the wound package may be uneven.
  • a yarn extending from the contact roller to the wound package, contacts with the surface of the empty bobbin forming a large contacting angle therebetween, when fully wound package is changed. Accordingly, the yarn may be slack, and consequently, bobbin changing efficiency may be lowered.
  • a yarn winding apparatus according to the preamble of claims 1 and 6 is known from US-A-2,789,774.
  • This document discloses a device having a stationary shaft with two articulated arms rotatably mounted thereon in spaced relationship.
  • An arbor is mounted to the free end of each articulated arm for carrying a mandrel used to wind up the yarn.
  • the two articulated arms and the associated mandrels follow an essentially circular path, the center of rotation being the stationary shaft.
  • the device disclosed in US-A-2,789,774 requires a fairly large amount of space.
  • the space required for installation of the winding apparatus is a sum of a diameter of fully wound package and a diameter of an empty bobbin, and thus, the required space can be about 3/4 of that required for a conventional yarn winding apparatus of a turret type.
  • a stand-by bobbin holder can be located near the contact roller previous to the changing operation, since a bobbin holder having an empty bobbin mounted thereonto can be moved independently from another bobbin holder having a fully wound package mounted thereon. Therefore, the time, which is required between the relief of a fully wound package from a contact roller and the contact of an empty bobbin to the contact roller, can be shortened. As a result, the rotational speed of the contact roller can be kept at a substantially constant speed during the changing operation.
  • the angle formed by the yarn contacting with an empty bobbin can be smaller compared with that in the conventional bobbin winding apparatus of a turret type, while the direction of the peripheral speed of an empty roller is opposite to the yarn running direction. Accordingly, the yarn can be prevented from being slack at a high speed, and fluffs in the yarn can be minimized, and further, bobbin changing efficiency can be enhanced.
