Definitions

  • Conventional cross-winding machines as shown diagrammatically and in plan view in Figure 1 of the accompanying drawings, comprise a spindle V for the formation of a bobbin RC thereon, arranged horizontally and mounted cantilevered on the end portion of a powered spindle shaft M which, in turn, is supported on the end portion of an arm B which is pivotable about a stationary axis A which is parallel to said spindle.
  • a cylinder-and-piston unit (not shown) can swing the arm B so as to move and maintain the spindle shaft M either to the station K where a bobbin is formed, or to the station K' (suitably spaced from the station K) where said bobbin is tied-in, is severed from the yarn coming from the winding machine, and, finally, is discharged.
  • said spindle shaft M is at the station K, said spindle V substantially engages with, and is parallel to, a roller T which is comprised in the traversing device which reciprocatingly moves the yarn over the spindle to effect the so-called traversing or helical cross-wound formation that characterizes usually the winding of a bobbin.
  • the spindle V is provided, at the free end thereof, with teeth D parallel to its axis, to quickly engage with the leading end of the yarn F and disengage therefrom when desired.
  • the arm B carries the spindle shaft M back to the station K and, then, the operator engages the leading end of the yarn with the toothed end of the spindle V and finally he activates said spindle shaft M and the cross-winding machine to form a new bobbin.
  • the object of this invention is the complete automation of the step of tying-in the bobbin, the step od discharging and severing the bobbin from the yarn coming from the winding machine, and of the step of engaging the new leading end of the yarn with the toothed end of the spindle V.
  • a cross-winding machine has been modified as follows:
  • the shaft 2 is partly mounted, so as to be axially slidable, within a bushing 4 which, in turn, is rotatably mounted by means of ball-bearings 5 within a body 6 which is fixed at the top of a supporting stand 7.
  • the portion of the shaft 2 that is to be enclosed by the bushing 4 is provided with a longitudinal spline 9 engaged with a key 10 which is fixed to said bushing 4.
  • the rear end of said bushing has keyed thereto a toothed pulley 11 which is connected, through a toothed pulley and belt system 12-13, to a motor-reducer unit 14 having an internal brake and secured to the base of said stand. 7.
  • the shaft 2 protrudes from the rear end of said bushing 4 and it mounts, with the intermediary of a bearing 15, a disc 16 provided with opposite flats 17 at right angles to said shaft 2 and slidably mounting therein sliding blocks 18 having pivoted thereto at 19 the ends of a fork-like member 20 which is fulcrumed at 21, normally to said shaft 2, to a support member 22 secured to said stand 7.
  • the lower end of the fork-like member 20 is pivoted at 23 to the piston rod of a fluid-operated cylinder-and-piston unit 24 the body of which is pivoted at 25 to said stand 7.
  • the numerals 26-26' indicate two sensors fixed to the support member 22 and detecting the inactive and active positions, respectively, of the fork-like member 20.
  • the numerals 28 and 29 indicate two further proximity switches which are mounted: the former on the support member 22 and the latter on the stand 7 and which co-operate with respective members 30-31 which are fixed to the periphery of the pulley 11, so as to detect when the shaft 2 is in its active operative position as from Figures 3-4 and to detect two pre-established positions in the round angle of said pulley 11, and to detect as well the rotations imparted to said pulley and elements associated with the shaft 2.
  • the stand 7 is mounted with its baseplate 107 on an additional baseplate 32, with the interposition of guiding and sliding means 33 parallel to the shaft 2 and provided with a control screw system 34 by means of which the stand 7 and associated elements may be moved to adjust the latter to the position of the toothed end D of the winding spindle V which is interchangeably mounted on the spindle shaft M, in order to form bobbins of different lengths.
  • the numeral 35 indicates a circuit which is fed through a lubricating nipple 36, by means of which the sliding surfaces of the elements 2 and 4 may be lubricated.
  • the numeral 27 indicates an axial conduit in the shaft 2, which is plugged at the front end as shown at 37 and is connected at the rear end with a rotation joint 38 by means of which said conduit 27 can communicate with a source of pressurized fluid or can communicate with a discharge means.
  • the conduit 27 comprises a branch 127 having connected thereto a flexible hose 39 for a purpose to be explained hereinafter.
  • the shaft 2 is formed with a pair of flats 40 which are parallel to each other and at right angles to the longitudinal axis of said shaft; secured to said flats by a pair of bolts 41 (see also Figure 7) are two parallel identical plates 42-42' having substantially the shape of a square and having pivoted at an end thereof, on a shaft 43 normal to said shaft 2 and suitably spaced therefrom, the body of a fluid-operated cylinder-and-piston unit 44 of the single-acting type, which is connected to the feeding hose 39 mentioned above.
  • the body of the unit 44 is urged by a spring 45 which is anchored to the plates 42-42', so as to engage normally against an adjusting screw 46 mounted on a lug 47 secured to said plates.
  • the axis of the unit 44 is substantially parallel to the longitudinal axis of the shaft 2 or is slightly diverging as shown in Figure 6.
  • the piston 144 of the unit 44 is urged to its rest position by a spring 48 arranged in a rear chamber of said unit, said chamber being freely communicating with the atmosphere.
  • the front chamber 244 of the unit 44 communicates with the hose 39.
  • a needle 50 Secured to the piston 144 and axially in line therewith is a needle 50 having a sufficiently rounded beard or hook 150 so shaped as to hook the yarn coming from the cross-winding machine.
  • the needle 50 is axially slidably mounted in a sleeve 51 which is secured to the body of said unit 44 and is of such a length whereby when said unit is at rest, the hook of the needle 50 protrudes to an appropriate extent from the end 151 of said sleeve.
  • the end 151 of said sleeve is shaped substantially as the mouthpiece of a flute and is so directed whereby when the unit 44 is activated for retraction, as shown in Figure 9, said hook 150 of the needle 50 will contact the foremost edge of the end 151 of said sleeve 51 so as to form therewith a closed slit wherein the yarn F will be slidably anchored.
  • the assembly 50-51 described above is suitably projecting away from the shaft 2, as seen in Figure 6.
  • the plates 42-42', at the portions designed for connection with the shaft 2, are formed with longitudinal slots 52 (see Figures 4-7) whereby the distance of the assembly 50-51 from the axis of the shaft 2 may be adjusted, so that said distance may be suitably larger than the radius of the bobbin just formed on the spindle V.
  • the assembly 50-51 When the apparatus is at rest, the assembly 50-51 is in the position shown in Figure 2, is arranged on the side of the shaft 2 that is facing toward the station K, and lies on an imaginary horizontal plane containing the axis of the shaft 2. This positioning is controlled by the group of sensors 31-29 (or 28-30).
  • a plate 53 carrying two devices 54 and 55 in cantilever fashion is secured on a side of the stand 7 so as to be adjusted to conform with the different diameters of the bobbins.
  • the device 54 comprises pressure-clamping means and cutting means facing, respectively, toward the station K and the station K'
  • the device 55 comprises a fork-shaped yarn guiding means best shown in Figure 12, which is mounted on a slide 56 which is slidably mounted within a stationary guide 57 parallel to the spindle shaft M, said slide being connected to a fluid-operated cylinder-and-piston unit 58 which may be controlled to move the yarn guiding device 55 from the position shown with solid lines to the position shown with dash lines, and vice versa.
  • the movement of the slide 56 is detected by suitable sensors 49-49'.
  • the devices 54 and 55 are arranged so that when a bobbin is transferred from the station K to the station K', the yarn connecting the bobbin to the cross-winding machine will suitably get inserted into said devices.
  • the apparatus described above operates as follows. Upon completion of the bobbin RC, the spindle shaft M is stopped together with the traversing device T, so that the last turns of yarn which have been wound on the bobbin are adjacent the right-hand end of said bobbin (looking at Figure 4).
  • the yarn F is suitably tensioned by means of an appropriate control of the assembly of pulleys P, whereafter the arm B is oscillated to transfer the spindle and bobbin from the forming station K to the tying-in and.discharging station K'.
  • the tensioned yarn connecting the bobbin to the device T of the cross-winding machine will move automatically to the necessary co-operating position with the devices 54 and 55.
  • the cylinder 24 ( Figure 3) is now activated automatically and moves the shaft 2 toward the spindle V to introduce first the centering tapered end 102 thereof into said spindle and then to effect the end-to-end coupling between the toothed bushing 1 and the front teeth D formed on said spindle, as shown in Figure 4.
  • the next step is the activation of the motor-reducer unit 14 to rotate the assembly M-V and bobbin RC as well as the shaft 2 with its equipment 50-51 at an appropriate speed, in clockwise direction, looking at Figure 2.
  • the yarn guiding device 55 is in the position shown in Figure 12 with solid lines, whereby - due to the rotation of the bobbin - an apprpriate number of turns FX are formed in the region of the bobbin onto which sleeve 51 has been superimposed, and said turns force the assembly 50-51 to contact said bobbin, against the action of the spring 45, as shown in Figure 4.
  • the yarn guiding device 55 is moved automatically to the position shown with broken lines in Figure 12, so that one turn or a portion of one turn FX' of said yarn F may reach the loop of the hook 150 of said needle 50, whereafter the unit 14 is automatically stopped and braked so as to stop the assembly 50-51 in a pre-established position, for example above the bobbin.
  • the step of Figure 9 is now effected automatically.
  • the cylinder 44 is activated to retract the needle 50 so that the hook 150 thereof will be moved to a co-operative position with the foremost edge of the end portion 151 of the sleeve 51, whereby the assembly 50-51 will clamp the yarn F though the latter may slide.
  • the cylinder 24 is activated ( Figure 3) to bring the apparatus again to a rest position and to retract the assembly 50-51 which, thus, effects the step of Figure 10.
  • the tail end of the yarn forming the bobbin is pulled with a U-shaped configuration FX' beneath the last turns FX, which hold ir firmly by virtue of the appropriate tensioning imparted to said last turns.
  • a suitable control discontinues the feeding of the cylinder 44 which will move the needle 50 outwards to protrude again completely from the sleeve 51 whereby, due also to an appropriate rounding off of the hook 150, said needle will release the now tied-in tail end FX' and the assembly 50-51 will return to its rest position as shown in Figure 6 due to the action of the return spring 45.
  • the device 54 is activated automatically to cut the yarn F from the winding machine and to frictionally retain the new leading end.
  • the bobbin RC tied-in at the station K', is thus separated from the winding machine and may be discharged.
  • the spindle V is retracted into the body of the spindle shaft M and the bobbin RC, retained by the stationary collar E, Will fall onto suitable collecting means (not shown) to be carried away.
  • the arm B is raised to bring the assembly M-V back to the station K, close to the device T where, as shown in Figure 2, the axis of the spindle V lies substantially on the same imaginary plane containing the length of yarn F which is tensioned between the elements T and 54.
  • its toothed end D necessarily engages said length of tensioned yarn F.
  • the subsequent activation of the spindle shaft M pulls the leading end of the yarn F away from the device 54 and said yarn will be automatically held firmly by the spindle V for the formation of a new bobbin.
  • the devices 54 and 55 will be returned to their rest position.
  • the device 54 comprises a slider 59 formed with an upper recess 60 having an inclinated side 160, said slider being disposed parallel to the spindle shaft M and being connected for movement to the rod of a fluid-operated cylinder-and-piston unit 61.
  • the free end of the slider 59 is enclosed in a guide bore 62 formed in a stationary body 63 having affixed to its opposite sides one blade 64 and leaf springs 65, respectively.
  • the yarn F from the winding machine engages the recess 60.
