  • the instant invention is therefore directed to a conveyor for conveying both empty bobbins and bobbins wound with a strand of yarn.
  • the single conveyor includes means for spacing of wound bobbins being doffed onto a conveyor from incoming empty bobbins and of downstream means for sorting the wound bobbins from empty bobbins being circulated about the machine to stations requiring the empty bobbins.
  • the instant invention also relates to a method of delivering empty bobbins and removing wound bobbins by employing a single conveyor about, for example, a spinning machine, which includes the spacing of the wound bobbins from empty bobbins and of sorting of these bobbins.
  • FIG. 1 is a top plan schematic view of the bobbin conveying mechanism of the instant invention.
  • FIG. 2 is a side elevational view on an enlarged scale of a switch mounted on a-crank arm and associated with the sorting mechanism showing a wound bobbin engaging the switch butt end first taken along lines 2-2 of FIG. 1.
  • FIG. 3 is a side elevational view on an enlarged scale of the switch of FIG. 2 showing an empty bobbin engag ing the crank arm of FIG. 2 apical end first.
  • FIG. 4 is a side elevational view of the bobbin stop and the bobbin guide mechanism of the instant invention and showing the mechanism in a retracted position in phantom; and i FIG. 5 is a top plan view of the bobbin stop and bobbin guide mechanism of FIG. 4.
  • a single conveyor 10 is positioned about a spinning machine M having opposing banks of spinning stations S and a tender T for patrolling movement about the machine to service the sta-' tions.
  • Incoming empty bobbins B for supplying the winding stations of such a spinning machine are shown upon the conveyor 10 and are introduced to travel about the machine apical end first as shown by the arrow 12.
  • an auxiliary conveyor 14 is operatively positioned with respect to conveyor 10 so as to convey full bobbins away from conveyor 10 to a hopper 16.
  • a limit switch 18 is positioned to the frame F-of the conveyor 10 upstream from the auxiliary conveyor 14 at least the length of a bobbin so as to intercept a wound bobbin B being conveyed away from the stations of the machine but which allows an incoming empty bobbin to pass without contacting of the switch.
  • a vertical deflector plate 20 ispivotally journalled about a shaft 22 which is fixed to the frame I F of the conveyor 10 so that the deflector plate is pivotal from an open or retracted position-to a blocking 7 position of the conveyor 10 as shown by the arrow 24.
  • a double acting air piston 26, having-a piston-rod 28 slideable therein, is suitably mounted to the frame F of the conveyor 10 and is pivotally secured to the end of the deflector plate 20.
  • the deflector plate 20 is in turn journalled about the shaft 22, so that, when the piston 26 is actuated by a signal produced when the butt end of a wound bobbin engages the limit switch 18, the piston rod 28 is extended to pivot the deflector plate to the blocking position, which is also a deflecting position, and deflect the wound bobbin onto the auxiliary conveyor 14 and then to the hopper 16.
  • a limit switch 30 Positioned on the auxiliary conveyor and at least the length of a bobbin from the conveyor 10 and so as to intercept the wound bobbin diverted from the conveyor 10 is a limit switch 30, which, when contacted by the bobbin, reversably actuates piston 26 to retract the rod 28 and move the deflector plate to-the open or retracted position to open the conveyor 10.
  • the limit switch 18 is carried on a crank arm 32 which is rotatably attached to the conveyor frame F by means of a pin34.
  • the crank arm and the switch are positioned so that the butt end of a wound bobbin engages the limit switch 18 as the wound bobbin is carried upon the conveyor 10 which pivots the crank arm upwards, as shown by the arrow 36, to override the bobbin with the switch 18 actuating the piston 26 .to move the deflector gate from the open to the blocking position thereby and deflecting the wound bobbin, as aforementioned.
  • deflector gate would normally be stationed in the blocking position and then a signal produced to open the gate by engagement of the switch 18 by the apical end of an empty bobbin.
  • the switch 30 would suitably be positioned downstream from the deflector gate 20 and on the conveyor for engagement with an empty bobbin to pioduce a signal and return the deflector gate tothe blocking position.
  • An appropriate typeof. device which is positioned two spaced apart guide members 42 and 44 fixedly secured together by means of a shaft 46 and snap rings 48 and 50 about the shaft and adjacent the outside surface of the members 42 and 44, respectively.
  • the shaft 46 is in turn rotatably journalled to brackets 52 and 54 which are fixed to the frame F of the tender T in any suitable fashion, such as with a bolt 56 and a nut 58, and a bolt 60 and nut, not shown, respectively, with the shaft having a portion 62 extending outwardly from member 42.
  • a bobbin ramp member 70 is positioned on the top of the guide members 42 and 44 and is rotatable secured tothe upper portions of the members, as shown, by means of downwardly extending tabs 72 and 74 journalled intermediate the members 42 and 44 about a rod 76 fixed to the guide members 42 and 44-
  • a guide 78 having an outwardly extending tab 79 is positioned intermediate the guide members 42 and 44 and the frame F and is rotatable with respect to the members 42 and 44 by means of a shaft 80 fixed to the member 44 and rotatably journalled to the guide 78, as more clearly shown in FIG. 5.
  • the guide 78 includes an arcuate shaped slot 82, shown in FIG.
  • the bobbin stop 86 so that if, when the bobbin stop is lowered, the bobbin stop engagesa passing bobbinbeneath it upon thecontinuously moving conveyor the bobbin stop will resiliently ride over the bobbin and then be urged into a blocking position after the bobbin passes to stop a succeeding bobbin while the conveyor. slides beneath it.
  • double acting air piston 100 having a piston rod 102 slideably therein, is vertically mounted to a bracket 103 by means of a bolt 104 with the bracket mounted to the frame member F of the tender T by means of. bolts 105 and 106, shown in FIG. 5.
  • the end of the piston rod is threaded into a boss 107 and secured thereto by a nut 108.
  • the boss in turn is rotatably connected to a link 109 by means of a pin 1 10 and the link is in turn fixedly secured about the end of the shaft 46 by means of a cap 1 12 so that as the piston isactuated the bobbin stop 86, the guide 78, and ramp 40 are raised and lowered.
  • limit switch 114 is mounted on the frame and posi- A tioned so as to be engaged by the tab 79 when the ramp 40 and the bobbin stop 86 are lowered in response to actuation of the piston and retraction of the rod In operation the ramp 40 and the bobbin stop 86 are in the retracted position, as shown in phantom in FIG.
  • a wound bobbin proceeds downstream the butt end engages the limit switch 18 to activate the piston 26 and thereby extend the deflector plate 20 to a blocking position.
  • the wound bobbin is' thereby diverted onto the auxiliary conveyor 14 where it engages the limit switch 30 to reversably actuate the piston 26 and retract the deflector plate 20 to the open position to allow following empty bobbins to pass about the end of the machine upon the conveyor 10.
  • the aforementioned time delay ensures that an empty bobbin is sufficiently spaced behind a wound bobbin so that it will not follow a wound bobbin onto the auxiliary conveyor 14.
  • a circulating empty bobbin does not engage the limit switch 14 but rather rides under the crank arm 32 and continues circulating 7 upon the conveyor 10 about the spinning machine.
  • the reverse arrangement may be provided wherein an empty bobbin actuates the switches 18 and 30 to move the deflector gate between the deflecting and open positions rather than a wound bobbin.
  • the wound and empty bobbins must circulate upon the conveyor 10 in opposite orientation. That is, if empty bobbins are circulating apical end first then the wound bobbins are conveyed butt end first, and vice versav
  • the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, all of which are intended to be encompassed by the appended claims.
