Definitions

  • a yarn winding machine having a row of winding positions, including an extra position, and an arrangement of roller and hook-end guide units adapted to permit transfer of the yarns, without operational interruption, to provide a row of yarns in a vertical string-up under one condition of operation, and a row of laterally spaced yarns in a right-angle string-up under a second condition of operation; and, a method for transferring yarns, one by one, from a take-up bobbin at a winding position to an empty bobbin at a stand-by position by forming a loop in a yarn end at a predetermined point along its length traveling to the take-up bobbin, and in one continuous step guidingly extending the loop laterally and vertically downwardly to pass around the empty bobbin and then effecting simultaneously, an automatic break in the looped yarn traveling to the take-up bobbin and a transferred take-up of yarn on the empty bobbin.
  • Conventional yarn winding apparatus in general, comprises an upright arrangement of a plurality of side-byside yarn winding positions each serving to take up a Single yarn end. At each winding position, there is a driven feed roll that forwards a yarn end to a traverse device which in turn leads the yarn to a driven bobbin upon which the yarn llS collected.
  • a packaged bobbin conventionally, an operator cuts or breaks the yarn being taken up on a bobbin, pulls the packaged bobbin away from a drive roll, and replaces the packaged bobbin with empty bobbin. While the packaged bobbin is being dolfed, one end of the cut yarn winds around and collects on the driven feed roll. After lacing the yarn onto the empty bobbin an operator must remove the waste yarn accumulated on the driven feed roll. When this procedure is carried out at each position, a high percentage of operating time is lost and a large quantity of waste yarn is produced.
  • Tandem windup that is, taking up two yarn ends simultaneously at one position on tandemly driven bobbins is also employed. Tandem windup, however, is a system still requiring separate position operation with consequent loss of time in the transfer of yarn ends.
  • Recent development is in the direction of providing an uninterrupted system where the transfer of yarn ends is integrated through all of the winding positions in a more simplified and less expensive manner.
  • Another object of the invention is to provide a yarn winding apparatus with means providing a procedure for transferring moving yarn ends from packaged to empty bobbins, serially, back and forth through all of the winding positions without interruption and with each separation of yarn from a packaged bobbin and lace-up "ice upon an empty bobbin occurring simultaneously and automatically.
  • Another object of the invention is to provide a simplified, expeditious and inexpensive method and apparatus for handling the winding and dofling of yarn packages on a tandem position Winding machine.
  • the novel apparatus comprises a plurality of single and multiple roll guide units, J-guides, traverse means and bobbin chuck drives arranged on an upright frame in predetermined organization to form an interrelated winding system.
  • a plurality of driven feed rolls one less than the number of winding positions, forward the yarn ends to the winding positions. In operation, one winding position is always a spare or idle position.
  • the apparatus is divided into winding positions and feed rolls; however, it will be understood that the apparatus is integrated in structure.
  • each of a plurality of yarn ends passes around a respective feed roll and is delivered to a winding position to be collected on a bobbin.
  • all of the yarn ends travel directly from the feed roll into a winding position and are taken up.
  • the yarns taken up at each position In a second condition the yarns taken up at each position and are taken up.
  • the yarns taken up at each position are delivered from a guide roll of an adjacent position.
  • one end winding position is idle.
  • a transfer operation is begun by changing the path of travel of the yarn to cause the yarn being taken up in the position next to the idle position to detour through the idle position and then to eflect an automatic break in the yarn end between the idle and take up positions.
  • the winding position from which the yarn end was transferred to the idle position then becomes the idle winding position, after the packaged bobbin is replaced with an empty bobbin, and the yarn end being taken up at the adjacent winding position is then detoured to it and a transfer effected thereto.
  • the same procedure is followed, serially, through all of the winding positions.
  • the method of deviating the path of the yarn end from one position to the other when the yarns are being taken up in the one condition is to form a loop within the yarn end and to extend the loop from the yarn take up position through the idle position.
  • the yarn is already passing over a roll guide of the idle position and it is only necessary to form a loop therefrom through the other components of the idle position.
  • the loop passes around the spare bobbin which is in a dolf position removed from the drive roll.
  • An auto matic break in the yarn is effected by bringing the spare bobbin into engagement with its corresponding drive roll after an extra loop of the yarn is taken around the spare bobbin.
  • the spring-up of the yarns is organized so that the paths of the yarns do not intersect and so that the yarns are not traveling in overlayed relation.
  • One feed roll is adapted to deliver yarn to two positions in alternate sequence.

  • the novel yarn winding apparatus is shown in one embodiment in FIGS. 1 and 2.
  • the illustrated configuration is designed for processing four yarn ends; however, it will be understood that the apparatus may be constructed for processing more or less number of yarn ends.
  • the yarn winder comprises an up right frame 1 having a plurality of driven feed rolls 2, 3, 4 and 5 mounted in spaced, horizontal row alignment along the upper end of the frame.
  • Four yarn ends A, B, C and D are each laced around a feed roll 2, 3, 4 and 5, respectively.
  • Below the feed rolls there is a horizontal alignment of five roll guide units.
  • a single roll guide 6 is mounted below and to the left side of feed roll 2 and another single roll guide 7 is mounted below and to the right side of feed roll 5.
  • Three pairs of closely spaced and angularly off-set roll guides 8 and 9, 10 and 11, 12 and 13 are arranged between and below the driven feed rolls.
  • the rolls of the guide units preferably, are rotatable.
  • one roll is mounted lower than the other and off-set to one side thereof to permit traversing and transfer of the yarn ends as will be explained later.
  • the J-guides have a predetermined width at the mouth between the arms to permit the yarn to move back and forth therein without contacting the arms of the guides when the yarn is being traversed.
  • the free arms of the J-guides are further provided with hooked ends.
  • each J-guide there is a traverse means 19, only one of which is shown for purposes of clarity of illustration.
  • a bobbin chuck with a. respective bobbin 20, 21, 22, 23 and 24 mounted on each chuck.
  • the bobbins are each driven by respective drive rolls driven through a main shaft.
  • a pivotal swing arm 25 at each winding position is provided for moving the bobbins away from their corresponding drive rolls into a doif position out of engagement with the drive rolls.
  • each of the four yarn ends A, B, C and 1D is wound around a respective feed roll 2, 3, 4, and 5.
  • Yarn end A is wound around driven feed roll 2 and is forwarded downwardly to roll guides 8 and 9, as shown in FIG. 1.
  • the yarn end contacts roll guide 8, only, and moves downwardly in the plane of and within the mouth of, but not in contact with, J-guide and then travels downwardly into lace-up within traverse guide 19 and then is taken up on bobbin 21.
  • Yarn ends B, C and D are laced up similarly with the yarn ends contacting roll guides 10, 12, and 7, respectively. In this lace, up the yarn will be taken up on bobbins 21-24 with the roll guide 6, J-guide 14, and bobbin 20 not being used but acting as spares.
  • Bobbin 20 is in a deft position removed from its drive roll.
  • bobbins 21-24 are packaged with yarn and a transfer or shift of the yarn ends is to be effected from right to left, that is, transferring all of the yarn ends one by one to an adjacent bobbin on the left.
  • the yarn end A will be traveling from driven feed roll 2, around guideroll 8, around guide roll 6, through the opening of J-guide 14, through traverse guide 19, around bobbin 20, back up through the traverse guide 19, up through and over J-guide 14, over to and through J-guide 15, and down to bobbin 2]. via a traverse guide 19.
  • the operator then quickly makes another loop of the yarn around bobbin 20 and engages the latter to its corresponding drive roll.
  • the yarn Upon engagement of bobbin 20 with the drive roll, the yarn automatically breaks in the length between bobbins 20 and 21 due to the stress applied to the yarn by the slower speed of rotation of bobbin 21 in relation to the speed of bobbin 29.
  • end D will be traveling from driven feed roll 5, over roll guide 7, downwardly through the mouth of J-guide 18, through a traverse guide 19, around bobbin 24, upwardly throughv traverse guide 19 and through J-guide 18, over to and around roll guide 13, downwardly through J-guide 17 to bobbin 23 via a traverse guide 19.
  • the operator makes another loop around bobbin 24 and the latter is then brought into engagement with its corresponding drive roll causing the yarn to break in a portion between bobbins 23 and 24.
  • the yarn will now be collected on bobbin 24 and will be traveling directly from feed roll 5, over roller guide 7, through the mouth of J-guide 18 but, not contacting the latter, through a traverse guide 19 and collected on bobbin 24.
  • Packaged bobbin 23 will be doffed and an empty bobbin will be substituted therefor.
