Definitions

  • the ter filament as employed herein is intended to define a single fil'unent or a plurality of filaments in twisted or untwisted condition, a textile yarn or thread or a braided collection of yarns or threads.
  • the apparatus is applicable primarily to the winding of textile filaments, but it may also be used for the changing of bobbins upon which other than textile filament material is wound, for example fine wires.
  • the term bobbin is employed in its usual sense herein, but is also intended to include spindles upon which a filament is uniformly wound. In the present apparatus the bobbin is driven through contact with a driven roller.
  • the apparatus of the present invention enables quick and positive removal of a filled bobbin from the machine and replacement with a fresh bobbin during the winding process, while also providing for severance of the filament from the filled bobbin and automatic threading onto the fresh bobbin.
  • the device of the present invention comprises a primary bobbin receiving the filament being wound and driving means therefor comprising a driven cylinder or roller in peripheral contact with the periphery of the primary bobbin.
  • Means are provided for maint ing the primary bobbin in an operational or winding position, while preventing displacement thereof in the direction of rotation of the driving cylinder.
  • the apparatus also includes means remotely positioned from the bobbin drive for receiving the bobbin when it is filled to a predetermined degree and for retaining the filled bobbin in a position of rest spaced from the driving means.
  • a reserve bobbin and means for disposing this reserve bobbin in rotatable engagement with the driving means so that the same receives the winding filamerit and conveys it in a direction relative to the primary bobbin in its position of rest to form a slack filament loop intermediate the bobbins, and finally means are provided which cooperate with the reserve bobbin in its operative position to press the filament loop thereagainst thus tensioning and tearing the same.
  • One embodiment of the present invention provides for manual changing of bobbins, while in another embodiment bobbins are changed automatically. However, in both cases the reserve bobbin when in operational Winding position and the filled bobbin when in a condition of rest are so positioned that the aforementioned loop is formed and the filament is torn by the device.
  • FZGS. 14 are schematic elevations of the manual bobbin changing device hereof, illustrating the position of various elements at different stages of the winding and changing process, and
  • FlGS. 5-9 are similar schematic elevations of the automatic changing device of this invention.
  • the apparatus comprises a driving cylinder ll suitably supported by means not shown which itself is driven in the usual manner by an axial shaft 12 in the direction indicated by the arrow.
  • the driving cylinder 11 is provided with a circumferential groove, indicated as the dotted line 13, in which the filament F to be wound is guided to a primary or winding bobbin 14, shown in FIGS. 1 and 2 in operational position with its peripheral winding surface in contact with the driving cylinder.
  • the filament F travels in the direction indicated by the arrow thereon and is supplied to the winding device from any suitable filament-forming or treating apparatus, not shown.
  • the axle 16 of the primary bobbin 1 is positioned in a vertical guideway 17 in each of a pair of carriers 18 which are desirably extensions of the machine frame. Only one carrier is apparent in the drawings.
  • the sides of guideway 17 are desirably provided with a suitable bearing material, not shown, to reduce wear and permit free rotation of the bobbin axle 16. From FIGS. 1 and 2 it will be seen that as the winding diameter of primary bobbin 14 increases its axle rides upwardly in the guideway 17 until the bobbin has reached a predetermined final diameter, at which time its axle is at approximately the position shown in E8. 2.
  • Each of the carriers is provided with a recess 21 into which is inserted a pin 22 disposed on the ends of extending arms 23 of the change device 19.
  • a second pin 24 is also disposed on the arms 23 for engagement with a tapered edge 26 of each carrier 18 when the pins 22 are introduced into the recesses 21.
  • the upper central surface of portion 20 of the changer is provided with recesses 28 and 29.
  • a reserve bobbin 31 is disposed with its axle 32 in recess 28, and in this position it frictionally engages the circumference of the driving cylinder 11.
  • the changer 19 also rotatably supports a pressure roll 33, which is positioned for frictional engagement with the periphery of reserve bobbin 31 when the latter is in the position shown in FIGS. 2 and 3.
  • the reserve bobbin is provided on its filament-receiving surface with a coating 3 having a high coefiicient of friction with the material of the filament F.
  • This coating 34 is illustrated as extending over the periphery of the empty reserve bobbin, but it may of course consist of one or a plurality of transversely extending strips of friction material.
  • the fully wound primary bobbin la is manually lifted out of guideway 17 and transferred to the recess 29 in the changer.
  • the filament F is continuously fed to the reserve bobbin 31. It moves out of the groove 13 in driving cylinder 11 and adheres to the friction coating 34- on the reserve bobbin, as shown in FIG. 3, moving toward primary bobbin 14. Since the primary bobbin is now in a condition of rest, a slack filament loop is formed between the two bobbins. As shown by the broken lines F and F (FIG.
  • this slack loop becomes longer and longer until it reaches a position indicated by P Then the free end of the loop passes into the nip between the reserve bobbin and the pressure roller 33.
  • the loop together with the filament from primary bobbin i i are then wound onto the reserve bobbin, but that portion of the loop leading to the primary bobbin is tensioned to such an extent that it is ultimately torn.
  • eserve bobbin 31 is manually lifted out of recess 28 and its axle 32 inserted into the guideway 17 of carrier 18, as shown in FIG. 4.
  • the weight of the bobbin brings it into frictional engagement with driving cylinder 11, filament F finds its way into the groove 13 and winding proceeds with the reserve bobbin now the primary bobbin.
  • the changer together with the fully wound bobbin is separated rom the carrier by releasing the bayonet closure.
  • the automatic device comprises a pair of identical carriers indicated at 41, only one of which is apparent in the drawings, suitably joined and arranged in fixed position as by attachment to the machine frame by means not shown.
  • Each carrier 41 is provided with a guideway comprising an ascending portion 42 which at its upper end joins a downwardly angled or descending portion 43, the lower end of wmch is provided with an opening 44 and a stop 46.
  • the ascending guideway receives the axle 16 of a primary bobbin 14 and maintains the bobbin in operational position against a driving cylinder 11, as described generally in connection with the embodiment of FIGS. 1-4.
  • the carrier 41 is also provided with another upwardly directed guideway 47 in which the axle 48 of a pressure roller 49 is positioned. Due to its position the pressure roller 49 bears against the winding periphery of the primary bobbin 14.
  • bobbin changers Coaxially with the shaft 12 of driving cylinder 11 there is pivotally mounted a pair of bobbin changers indicated generally at 51.
  • the carrier 41 there are of course two such changers, joined for cooperative movement, one disposed on each side of the drivnig cylinder 11.
  • One arm 52 of the changer comprises a plane upper surface 53 and the changer is so disposed that this surface is inclined downwardly away from the pivotal point of the changer.
  • a protuberance 54 adjacent the end of arm 52 supports the axle of a reserve bobbin 31, which bobbin is also provided with a coating 34 having a high coefiicient of friction with the material of filament F.
  • Another arm 56 of changer 51 is coupled as at 57 through a lever system to a moment control arm 58, which is pivotally mounted to a fixed external member as at 59.
  • the lever system consists of a bell crank 61 pivotal about a fixed point 62, to one arm 63 of which a connecting rod 64 is pivotally mounted.
  • the free end of connecting rod 64 is provided with a roller 66 which peripherally engages the plane underside 67 of moment control arm 58.
  • On the other arm 68 of the bell crank there is pivotally mounted a control rod 69, the lower end 71 of which is pivotally connected to arm 56 of changer 51.
  • control rod 69 passes through an opening '72 in a fixed flange 73, against which one end of a helical compression spring 74 surrounding rod 69 abuts.
  • spring 74 is supported by a fixed collar 76 on rod 69.
  • spring 74 tends to displace control rod 69 downwardly thus tending to rotate the changer 51 in the direction of rotation of drive shaft 12, i.e., counterclockwise as illustrated.
  • a stop 77 which may be a projection of the machine frame, abuts the surface 78 of the changer thus preventing rotary move ment in the opposite direction.
  • the primary bobbin 14 rises in the ascending guideway 42 as its diameter increases.
  • the arrangement and length of guideway 42, and the angle of descent of guideway 43 from the top of the ascending guide are such that when the bobbin has been filled to a predetermined degree, i.e., reaches a certain final diameter, the bobbin axle 16 is located at the point of transition between the ascending and descending guideways, as shown in FIG. 6. When this point is reached the axle of the primary bobbin then enters descending guideway 43 and the bobbin rolls down until it reaches the stop 46.
  • the filament F is lifted off of the driving cylinder and onto the friction surface 34 of the reserve bobbin by pressure roller 49, which securely fixes the filament to the friction surface.
  • the filament is being conveyed by the reserve bobbin in a direcion toward the resting primary bobbin, and since the latter bobbin is at rest a slack loop of increasing size, indicated by the dotted lines F and F (FIG. 9), is formed between the two bobbins. The size of this loop increases as indicated at F until the same ultimately passes into the nip between driving cylinder .11 and reserve bobbin 31.
