Definitions

  • the opening of yarn hanks is necessary, for example, when the hanks have to be placed upon a reel after dyeing.
  • it is relatively difficult or complicated to push the yarn hanks onto the arms since in order to prevent accidents, the arms must not be entirely closed on to one another i.e. to the minimum possible diameter. This is especially true when the arms are motor driven.
  • an important object of the present invention is to provide a simple, reliable and easily operated device for the opening of yarn hanks which can be operated without danger of accident.
  • Another important object of the present invention is the provision of an improved device of the type described adapted for opening a yarn bundle for application onto a carrying member in a reliable and safe manner.
  • Yet another important object of the present invention is to provide new and improved means for opening yarn hanks of the type provided with a plurality of movable arms, and including means operative with said movable arms to prevent movement thereof into their closed position when an obstruction is located between said arms.
  • Still a further object of the present invention is the provision of an improved hank opening mechanism which is extremely reliable in operation, easy to operate and manufacture, and functions in a safe manner.
  • a hank-opening device which comprises a number of supports which are movable from a closed position in which they conjointly form a guide to receive a yarn hank to an open position in which the supports expand the hank to receive a reel, and the supports are movable individually between the opened and closed position by drive means which include yieldable elements disposed to yield in the closing direction to obstruction to complete movement of the supports to their closed position.
  • the present invention relates to a hankopening device which comprises a number of approximately parallel arms movable between a closed end posi tion and an open end position, and a drive device for moving the arms in the opening and closing directions.
  • each arm is pivotably mounted, with preferably the pivoting axes of all the arms lying on a common circle or pitch, and with the free ends of the arms shaped to form conjointly a hank-receiving guide terminating in a point, and the arms are coupled individually with a drive means through a yieldable element disposed to yield in the closing direction of each arm.
  • the yielding function of the drive to close the arms can be constituted by springs or by pro-loaded stripping clutches for example.
  • FIGURE 1 is a front elevation of the device of the present invention
  • FIGURE 2 is a side elevation of the device shown in FIGURE 1;
  • FIGURE 3 is a front elevation of a portion of the drive housing with its cover removed;
  • FIGURE 4 is a cross-sectional view taken along the line IVIV of FIGURE 3 and additionally illustrating portions of the arms and associated sockets;
  • FIGURE 5 is a fragmentary view, partly in crosssection, schematically depicting a modified form of driving coupling arrangement.
  • reference numeral 1 indicates a drive housing having a plurality of drive spindles 2 extending from the front face 1a of the housing 1.
  • a support or arm 3 On each drive spindle 2 there is mounted a support or arm 3, with the forward extending portions 3a of all the arms shaped so that in the closed position as shown in FIGURE 2 the forward portions 34: extend parallel with one another so as to constitute a closed, nearly cylindrical guide or retainer for a yarn hank which is to be opened.
  • the hank is applied by being pushed onto the arms 3, for which purpose the free ends 312 of the arms 3 are tapered as is clearly shown in FIGURE 2.
  • the drive spindles 2 are driven by a suitable drive mechanism provided in the drive housing 1. As is shown in FIGURE 2, the drive mechanism is driven by an electric motor 5 through suitable reduction gearing arranged in a reduction unit 4 secured to the drive housing 1.
  • the reduction gearing of the reduction unit 4 can be formed for example by worm gearing in a manner known to the art.
  • Each of the drive spindles 2 are rotatably mounted in the drive housing 1 in two needle bearings 6 and 7.
  • the drive spindles 2 are disposed in a circle about a central drive pinion 8, one end of which is mounted in a needle bearing 9 and the other end of which is mounted in a ball bearing 16.
  • One end of the pinion 8 is provided with an extended spindle portion 11 which projects beyond the ball bearing 11 and has secured thereto a gear or toothed wheel 12 which is keyed against rotation by a key 13 to the spindle end 11.
  • the drive pinion 3 meshes with toothed segments 14 and 15 which are mounted to turn on the drive spindles 2.
  • the toothed segments 14 and 15 are oppositely directed and engage the pinion 8 in an axially offset manner, with each toothed segment 14 being arranged between two toothed segments 15 in the peripheral row of drive spindles 2.
  • Each drive spindle 2 also carries a drive arm, with the respective drive arms for segment members 14 being indicated at 16 and for the other segment members 15 at 17.
  • the drive arms 16 and 17 are secured against rotation on their associated drive spindles 2 by suitable pins 18 for example.
  • the toothed segments 14 and 15 are formed with dogs 14a and 15a (FIGURE 3) which are arranged to cooperate with the drive arms 16, 17 when the toothed segments 14, 15 are driven by the drive pinion 8 in a counter-clockwise direction, i.e. in the direction of the arrows 19.
  • On the hubs 14b and 15b of the toothed segments 14 and 15 are mounted respective torsion springs 20, one end of which is secured in bushings 21 secured by suitable pins to the drive spindles 2, while the other respective ends engage with the toothed u segments 14 and 15 themselves.
  • the yarn support arms 3 are carried by their drive spindles 2 by being mounted in sockets 22 secured to the associated drive spindle.
  • the operation of the device may be controlled by a conventional electric switch known to the art and having forward and reverse start and stop keys, which are operable for example by the foot, for the purpose of energizing and deenergizing the drive motor 5.
  • a conventional electric switch known to the art and having forward and reverse start and stop keys, which are operable for example by the foot, for the purpose of energizing and deenergizing the drive motor 5.
  • the gear 12 When the drive motor 5 is energized the gear 12 is driven through the reduction gear unit 4 and the gear 12 rotates the drive pinion 8. According to the selected direction of rotation of the drive motor 5, the drive pinion rotates either in the clockwise or in the counter-clockwise direction (FIG- URE 3).
  • the opened yarn position enables a suitable yarn reel, such as a spoked reel for example, to be introduced between the arms 3, and it then the drive motor 5 is reversed the arms 3 are swung through the intermediary of the toothed wheel 12-, the drive pinion 8, the toothed segments 14 and 15, the torsion springs 20 and the drive spindles 2 in the clockwise direction towards their closed position.
  • a suitable yarn reel such as a spoked reel for example
  • the coupling can consist for example, of a positive dog-coupling or jaw clutch effective in one direction and a slipping clutch coupling effective only in the opposite direction, whereby the transmittable torque of the slipping coupling is adjustable.
  • FIG- URE 5 there is depicted a variant form of the invention employing a slip type clutch or coupling arrangement.
  • the drive spindles provided with the lateral shoulder portions 31 against which bears a suitable friction disk 32.
  • a drive arm 33 is arranged on the opposite side of the friction disk 32 and is urged thereagainst by suitable springs 34 or the like, the force applying effect of which may be adjusted, and bearing against a collar or sleeve member 35.
  • the spindle 30 may be rotated into a yarn opening position.
  • the drive arm 33 will slip on the friction disk 32 if an obstruction appears between the support arms for the yarn.
