Definitions

  • the invention further contemplates a system embodying a stationary cutting edge that is adjustable, and a cutting zone, which is determined by the dimensions of the bobbins to be stripped.
  • Another object of this invention is to provide stop means at the front and rear of the cutting zone in order to control the cutting operation which can then be effected manually in a very eflicient manner, and the waste rayon can be removed from the bobbins as it is being severed.
  • FIG. 1 is a perspective view of waste-severing apparatus constructed in accordance with the principal of the present invention
  • Figure 2 is a top plan view of the waste-cutting stations of the apparatus of Figure 1;
  • Figure 3 is a view in vertical section taken along the line 3-3 of Figure 2;
  • Figure 4 is a view in vertical section taken along the line 4-4 of Figure 2.
  • a hopper I0 is provided for receiving a large number of bobbins containing thereon convolutions of waste rayon.
  • This hopper is mounted on legs II and contains two openings l2, through which the bobbins are permitted to fall into water trays l3 to furnish the supply at hand.
  • These water trays are leak-proof and are supplied with sufficient water to wet-out the waste material on the'bobbins, so that the coils of waste can be removed in the form of mats.
  • a platform I. is arranged in front of the water trays and is supported by legs I5. At the center of, and positioned on the platform is a skeleton framework It whichin turnserves as a support for a bobbin-guiding and yarn-severing mechaanism generally indicated at H.
  • the mechanism i1 is integrally flxed on the skeleton framework l6 and consists of two adjustably mounted stationary knives l8, bobbin guideways i9, and tubular member 20.
  • each knife per se consists of a vertically depending cutting edge 2
  • the forward cutting edges 2i of the knives are slanted toward the front of the platform and extend a predetermined distance upwardly between the interrupted guldeways i9, which guideways govern the horizontal movement of the bobbin.
  • the knives are mounted on inclined blocks 23 which rest on inclined blocks 24 which are integral with the mechanism I'l.
  • Blocks 23 are adapted to slide on blocks 24 but are held in fixed relation therewith by means of rods 25 which are screw-threaded at 26 to receive nuts 21 which ride in vertical slots 28.
  • Rods 25 are mounted in bearings 29 and 30 and are screw-threaded at their other ends to receive lock nuts 3
  • stops 32 and 33 are provided to limit the horizontal movement of the bobbins.
  • the tubular member 20 is centered between the guldeways l9 and serves as a stop to prevent movement of the bobbins in a direction transverse to theiraxes.
  • Adjacent the rear portion of each of the guideways is an inclined shelf 34, which acts to permit the bobbins to roll into inclined trays 35 after the bobbins have been cleaned.
  • bobbins containing waste rayon are continuously supplied to the trays from the hopper and are thereby wetted out.
  • the operator standing at the center of the platform in front of the machine takes in each hand a bobbin from each tray and in one operation places each bobbin against the respective front stops of each guideway and propels each bobbin by gripping the waste thereon until its abuts each rear stop, whereby the cutting blade of the knife engages the mat of waste rayon on the under side at one end of each bobbin and severs it during this stroke.
  • the operator who is holding the bobbins through the mats of waste rayon around the top of the periphery of the bobbins, slides the waste mats oil of the rear ends of the bobbins as a continuation of the motion used in pushing the bobbins along the guideways.
  • the cleaned bobbins abutting the rear stops, being supported by inclined shelves, will roll by gravity into the inclined collecting trays, from which they can be readily transferred to movable containers.
  • a process for stripping off waste threa wound arounda bobbin which comprises sequentially severing succeeding coils of waste on the bobbin while advancing the bobbin axially by imparting motion to the waste and through it to the bobbin and, after all the coils are severed,
  • a process for simultaneously stripping off waste thread wound around each of two bobbins which comprises first sequentially severing succeeding coils of waste simultaneously on each of the bobbins while simultaneously advancing the bobbins axially in parallel relationship by imparting motion to the waste, and through it to each of the bobbins, and then, after all the coils are severed, arresting the axial movement of both of the bobbins, passing the cut waste over the respective leading ends of the bobbins by continuing to impart motion to the waste after the motion of the respective bobbins has been arrested.
  • a process for simultaneously stripping off waste thread wound around each of two bobbins which comprises first sequentially severing succeeding coils of waste simultaneously on each of the bobbins while advancing the bobbins axially in parallel relationship by imparting motion to the waste and through it to each bobbin, then, after all of the coils are severed, arresting the axial movement of both of the bobbins while passing the cut waste over the respective leading ends of the bobbins by continuing to impart motion to the waste after the motion of the respective bobbins has been arrested, and finally discharging the bobbins by gravity radially from the respective position of arrest.
  • a process for stripping off waste rayon yarn wound around a bobbin which comprises initially soaking the waste-containing bobbin in water, then sequentially severing succeeding coils of waste on the bobbin while advancing the bobbin axially by imparting motion to the waste and through it to the bobbin and, after all the coils are severed, arresting the axial movement of the bobbin, passing the cut waste over the leading end of the bobbin by continuing to impart motion to the waste after the motion of the bobbin has been arrested and the frictional bond between the bobbin and the waste has been broken as a result of the severance of the component coils thereof.
  • a process for stripping oil waste rayon yarn wound around a bobbin which comprises initially soaking the waste-containing bobbin in water,
  • Apparatus for stripping waste yarn from a bobbin which comprises a guideway for guiding a bobbin for axial movement, a cutting knife mounted on said guideway to sever the waste on the bobbin as it is moved axially therealong and a a bobbin for axial movement, stops at both ends of said guideway for engaging opposite ends of,
  • cutting means mounted on said guideway to sever the waste on said bobbin as it is moved axially from a starting position in engagement with the first stop to a terminal position in engagement with a second stop, said cut- I ting means being located nearer to said first stop than the length of said bobbin, whereby the cutting means cannot engage the leading end of the bobbin but can engage the waste wound thereon.
  • Apparatus for stripping waste yarn from a bobbin which comprises a guideway for guiding a bobbin for axial movement, a .cutting knife mounted on said guideway to sever the waste on the bobbin as it is moved axially therealong, a-
  • stop for arresting the movement of the bobbin after passage of the waste thereon through the knife and means coacting with the bobbin and located adjacent said stop for causing gravity. movement of the bobbin away from the position of arrest.
  • Apparatus for stripping waste yarn from bobbins which comprises, a pair of primary guides, a secondary guide therebetween, said guides coacting to define two parallel'paths for guiding bobbins for axial movement and a knife in each of said primary guides to sever the waste on a bobbin as it is moved axially therealong.
