Definitions

  • This invention concerns a device for checking knots and for controls downstream from the slub catcher in winding machines.
  • the invention concerns a device which enables the quality of the knots to be checked as soon as knotting has taken place and which makes it possible to ascertain whether the yarn rising towards the yarn package during winding contains tangles, slubs, broken ends of thread or other like faults.
  • Some devices are hnown which perform the task of a slub catcher and check the knots as soon as the latter are formed.
  • another device may be required to carry out proper controls downstream from the slub catcher and to be able to . eliminate tangles in the yarn rising towards the yarn pack- . age, thereby improving the control already performed by the . slub catcher.
  • a purpose of the invention is to embody an improved single device for checking knots and for the controls downstream from the slub catcher, whereby said device is simple in con-. struction reliable and provides easy operation and adjustment
  • control on the yarn to be wound may also be conducted while said yarn is being transferred from the knotting position to the pos- . ition of the slub catcher, thereby substantially providing a continuous inspection of said yarn during the whole wind- . ing cycle.
  • the device of the invent- . ion comprises two blade means for controlling and guiding the yarn which extend lengthwise above the knotter and above.
  • the slub catcher so as to cooperate with both of them, whereby one of said blade means is located in a pre-set and per- . haps adjustable position, and whereby the other blade can be. moved or rotated from its open position of rest to its clos- . ed working position.
  • the length of time of the conditions of rest or of work can be varied by altering the reciprocal positions of read- . ing means and two-can means which cooperate with each other,. whereby the position of said reading means can be regulated . axially.
  • This invention is therefore embodied in a device for checking knots and for controls downstream from the slub catcher. in winding machines, said device being characterized by com-. prising:
  • the device 10 of the invention comprises means 11 for checking the yarn 12 with blade means 13, where by said blade means 13 consist of a fixed blade means 14 and. of a blade means 15 which can be moved and be at least par- . tially rotated, said two blade means being reciprocally pos-. itionable.
  • the opening or slit 16 between said two blade means 14 & . 15 within which the yarn 12 is guided and slides, is obtained by regulating the reciprocal positions of said blade means 14-15 by means of suitable adjustment means 17.
  • said opening is dimensioned to suit the basis of the diameter thereof and in relation to the size of. the faults and knots to be eliminated.
  • Figs. 1 & 2 show the means 18 which operate the opening . of the blades 14-15 and which consist of a cam 19 shown in an exploded view and keyed to the horizontal knotting shaft . 20, and of a reading pin 21 passing through an oscillating arm 22.
  • the axial position of said reading pin 21 can be regula- . ted so that said pin 21 can cooperate with one of two circular crowns 23-123, which are radially superimposed one above the other and into which the cam 19, rotating in direction A (Figs. 1 and 2), is divided so as to obtain a differing length of time for the opening or closing of the blades 14-15.
  • the circular crown 23 permits said blades 14-15 to be closed for a period limited to the knotting phase, whereas the crown zone 123 causes said bladed 14-15 to be closed during the normal winding phase.
  • said spring 27 is kept under axial compression between the end 30 of said piston 29 pushing against said. oscillating arm 22, and a resistance point 28 on the stat- iffy structure 26.
  • the other end 130 of the piston 29 keeps in a retracted or non-operational position the rotating blade 15, onto which the said end 130 is hinged (31).
  • Said rotating blade (15) comprises a second pivot 32 near. to the proceeding pivot 31, whereby said pivot 32 enables said blade 15 to rotate around the stationary structure 26 with an arm cf rotation of which the length is equal to the distance. betweene the two pivots 31-32 located in the end 45 of said . rotating blade 15.
  • Fig. 1 shows the position of rest of the device 10, where as Fig. 2 shows the same device 10 in its working position..
  • the reading pin 21 cooperates with the sector 124 of the circular crown 123 of the double . cam 19 and, to be more exact, with the front part 33 thereof. 19.
  • the checking of the knot just formed can be carried out in a position or zone 34 of the lengthwise slit 16 above the knotter 36.
  • the yarn 12 can be transferred thereafter by sliding tangentially on the fixed blade 14 up to the opposite zone 134 of said slit 16 abcve the slub catcher 37, said zone 134 cor7 responding to the position where said yarn 12 passes during . the winding phase, as shown in Fig. 3.
  • the mcvabel. blade 15 is shown with lines of dashes when it is in its po-. sition of rest (opened) and with a continuous line when it is in its (closed) working position.
  • Said fixed blade 14 comprises in said zone 134 a tangential porcelain guide 35, which enables said fixed bade 14 to cooperate better with the yarn 12 tangentially thereupon, and also comprises a protruding terminal stop 38, which prevents. said yarn 12 from escaping the control of the blade means 13.
