Definitions

  • This invention relates broadly to the drawing of continuous filaments from a source of molten glass, gathering the filaments into strands and cutting the strands into short lengths principally for use as a reinforcing medium in plastic molding. More particularly the invention pertains to an improved chopper for cutting the strands.
  • the chopper receives strands from packages or as gathered continuous filaments from a filament forming source.
  • the chopper includes a cutter roll with radially extending blades, a cot roll and an idler roll riding upon the driven cot roll.
  • the principal object of this invention is the provision of an improved chopper which operates smoothly at higher speeds, has accordingly greater production capacity, and processes strands directly as gathered from a continuous filament forming source.
  • a further important object of the invention is a chopper which is subject to less wear and maintenance cost and has lower power requirements.
  • FIGURE 1 is a side elevation of a chopper embodying one form of the invention and apparatus associated therewith shown rather diagrammatically for drawing continuous glass filaments from a molten glass source and gathering the filaments into a plurality of strands for delivery to the chopper;
  • FIGURE 2 is an end elevation of the chopper as viewed from the line 2-2 of FIGURE 1;
  • FIGURE 3 is a longitudinal, vertical section of a chopper embodying an alternate form of the invention.
  • FIGURE 4 is an elevational view of the right hand end of the chopper of FIGURE 3;
  • FIGURE 5 is an enlarged vertical section of the contact area of the cutter roll and cot roll of the chopper of FIGURES 3 and 4;
  • FIGURE 6 is a plan view of the chopper of FIGURES 3 and 4;
  • FIGURE 7 is an enlarged view with portions in section of the cutter roll of the chopper of FIGURES 3, 4 and 6 and five strands, diagrammatically indicated, being cut into short lengths by the cutter roll.
  • the strand chopper 10 shown in FIGURES 1 and 2 has a cot roll 12 which also serves as a filament pull wheel.
  • the cutter roll 13 has radially extending blades 14 which engage the peripheral surface of the cot roll 12.
  • the cot roll is driven through belt 15 and pulley 16 by a motor which is not illustrated.
  • the cutter roll is driven by the cot roll through the engagement between the blades 14 and the notches formed by the blades in the peripheral surface of the cot roll.
  • the blades 14 repeatedly severe the strands 19 passing between the two rolls into short lengths 17, most commonly either one quarter or one half inch in length, which are collected on the conveyor 18.
  • the strands 19 are gatherings of continuous filaments 20 drawn downwardly from minute streams of molten glass issuing from the tips 21 of the bushing 23 to which the molten glass is delivered from a glass furnace. Conventionally there are between two and four hundred tips in such a bushing.
  • the filaments are initially divided by the insertion of fingers 25 into strands groups each of which may usually include from twenty to eighty or more filaments. Thus segregated the filaments pass over the apron of the size applicator 27.
  • the strand groups of filaments are consolidated into compact strands by riding around grooves in the shoe 28.
  • the strands then pass around the idler wheel 29 in spaced relation before traveling upwardly upon the peripheral surface of the cot roll.
  • the frictional adhesion of the strands to the extended peripheral surface of the extra large cot roll is sufficient to generate the pulling force required to draw the filaments 20 from the bushing 23.
  • the size applicator, grooved shoe and idler wheel are of conventional design comparable to those shown and more fully described in U.S. Patent No. 3,265,482 which issued Aug. 9, 1966, to Langlois and Stream.
  • the overhanging or outboard positioning of the cot roll 12 in respect to the casing 30 of the strand cutter and on the end of the shaft 32 as seen in FIGURE 2 facilitates lacing of the strands around the cot roll at the start of operations.
  • the cot roll has a diameter, in this instance of approximately thirteen inches to provide the circumferential surface required in its function as a pull wheel.
  • the cot roll 12 has a width close to four inches and has a peripheral surface of a polyurethane composition tough and resilient in nature.
  • the cutter roll 13 is only about four inches in diameter inclusive of the blades which project outwardly three eighths of an inch. A cutter roll of this diameter has been found to function satisfactorily and may be built more accurately and at less expense than a larger model.
  • the cot roll shaft 32 is upported upon bearings mounted on the edges of casing 30.
  • the shaft 33 of the cutter roll 13 is held within bearings fixed to the upper ends of a pair of rocker arms one of which is indicated at 34 in FIGURE 1.
  • the lower ends of the rocker arms are pivotally carried on shaft 35.
  • Fixed to the center of the shaft 35 between the rocker arms is a collar 37.
  • a horizontal arm 38 projects from this collar to extend exteriorly of the end of the casing 30.
  • a second arm 42 extends upwardly from the collar 37. fixed to shaft 35 and receives the pressure of spring 43 carried on the rod 45. The latter is threaded at its outer end for receipt of the lock nut 46.
  • the tension of the spring swings the rocker arms on shaft 35 toward the cot roll and determines the pressure of the abutment of the blades of ,the cutter'roll against the surface of the cot roll up to the limit of movement permited by arm 38 meeting the set screw 39.
  • the strand chopper 48 of alternate design shown in FIGURES 3, 4 and 6 the structure is illustrated and described in more detail, and as many of the elements are similar to those of the chopper of FIGURES l and 2 the description of the alternate design will improve the understanding of the structure of the chopper 10 of FIG- URES land 2.
  • the cutter roll 52 with its radial blades 53 instead of being supported upon rocker 'arms has end shafts 55 and 56 which are mounted in bearings 57 and 58 set upon the opposite side edges of the casing 50.
  • the cot roll 60 is of smaller diameter (about six inches) than the cot roll 12 of the easlier described model and is lodged with its lower portion Within the casing 50. Access to it is not so essential nor is the large size, as here it does not serve as a pull Wheel but instead is adapted to receive strands from packages mounted upon a creel.
  • the cot roll 60 includes an inner cylidnrical shell 61 encompassed by a resilient sleeve 62 about five eighths of an inch thick of a polyurethane composition.
  • the sleeve is held in place by end retainers 63 and 64.
  • the shaft 65 of the cot roll extends through end hubs to rest in bearings 66 and 67. These are mounted upon the upper ends of rocker arms 68 and 69 similar to those supporting the cutter roll 13 of the chopper 10 of FIGURES 1 and 2.
  • the rocker arms are carried upon the pivot shaft 71 turnable in bearings 72 and 73.
  • a collar 75 is fixed to the center of shaft 71. Extending from the collar is the horizontal stop arm 76, the outer end of which projects exteriorly of the casing 50 through opening 77. Upward movement of the arm 76 and associated pivoting of the cot roll 60 toward the cutter roll 52 is limited by the set screw 78 threaded through bracket 79 and held in selected setting by the lock nut 80.
  • the upright arm 82 extending from collar 75 receives the' thrust of spring 83 held against the arm by the ad- 4. rigidly in precise position by end plates 110 and 111 fastened 'by' screws'112 and by the intervening polyurethane gaskets 113 and 114.
  • the polyurethane composition of the cot roll sleeve 62 is tough and resilient, it is pierced by the blades 53, and notches 102 are quickly formedin the surface of the sleeve as illustrated in FIGURE 5.
  • the circumferential dimension of the sleeve is selected to be evenly divided by the distance between the tips of adjacent blades and the blades are spaced evenly apart so the blades keep projecting into the notches first created by the blades. This establishes a strong traction between the cutter roll and the cot roll which synchronizes their rotation and transmits driving torque from the roll activated from a short lengths 107 as they pass between the cutterroll 52 and the cot roll 60.
  • the line of severance 109 is parallel with and slightly above the line of tangent contact be tween the two r'olls.
  • the work load is distributed since the strands are cut successively as each angled blade, progressive from left to right as viewed in FIGURE 7, moves across the line of severance.
  • the group of strands 106 are conventionally reciprocated lengthwise of the cutter roll.
  • the tension of spring 83 may be set by adjustment of screw'84 to apply the pressure necessary for penetration of the blades into the surface of the cot sleeve. A pressure of only 150 pounds has been found effective.
  • Entry of the blades into the notches is advisably limited initially. to one thirty second of an inch.1his is controlled by positioning set screw 78 against horizontal arm 76.
  • FIG- URES 6 and 7. Details of the cutter roll 52 are best disclosed in FIG- URES 6 and 7..In this chopper design the cutter roll is driven through pulley 99 on end shaft 56 with belt 100 engaging the pulley.
  • blades 53 of the cutter roll 52 are individually straight they are set in grooves running longitudinally of the peripheral surface of the roll but are angled slightly circumferensirable.
  • the sleeve may be removed-and its surface refinished by machining in a lathe. To reestablish tracking of the blades in the notches subsequently formed the reduction in diameter must be such that'the new circumference is still exactly divisable by thedistance between adjacent blades.
  • the features of the invention it-is desired toemphasize include the tracking. of the cutter blades in the initially formed notches, the angled positioning of the blades, the simultaneously engagement :of two or more blades in notches of the cot'roll, the cot roll having a substantiallylarger diameter than-that of the cutter roll,-one
