Definitions

  • This invention relates to a feed system for fiber combing machines having a reciprocating nipper frame, a nipper knife for gripping a web of fibers, a feed roller for feeding the web by lap form to the knife, and a drive mechanism for rotating the lap-feed roller to advance a web to the nipper knife in both directions of reciprocation of the nipper frame.
  • the present invention relates in general to fiber combing machines and, more particularly, to cotton combing machines operating on the principles of the well-known Heilmann comber.
  • a forward and reverse comber, nipper feed mechanism which feeds the lap to the nippers on both the forward and backward motions of the nipper frame cycle. Feeding on both the forward and backward motions of the nipper frame permits the combing machine to increase its production rate, per nipper frame, up to twice its previous amount, with no sacrifice in quality.
  • the comber nipper feed mechanism includes a nipper frame to which the cushion plate is attached and on which the nipper knife is mounted, a feed roll which cooperates with the cushion plate to feed the lap to the nippers, a rotary comb which combs the nipper fringe on the backward stroke of the nipper cycle, and a top comb which combs the fibers on the forward stroke of the nipper frame cycle.
  • a pair of detaching rolls seize the front ends of the fibers delivered by the nipper frame, and by their forward motion separate the tuft from the lap held by the feed roll.
  • a one-way clutch and housing is attached to each end of the feed roll; the first clutch being designed to rotate in lock direction and thus feed the lap to the nippers on the forward motion of the nipper frame, while the second clutch is designed to rotate in lock direction feeding lap to the nippers on the backward motion of the nipper frame.
  • a pair of adjustable links connects one end of each clutch housing to a fixed pivot located in the arms which carry the nipper knife.
  • the arms which carry the nipper knife and links pivot upwardly opening the knife and turning the two clutch housings in one direction.
  • This turning movement of the clutch housings rotates the first one-way clutch in lock direction driving the feed roll to feed the lap to the nippers while the second one-way clutch located at the opposite end of the feed roll rotates in slip direction.
  • FIGURE 1 is a cross sectional view through a portion of one of the combing heads
  • FIG. 2 is a perspective view showing a portion of the nipper frame and cushion plate with the forward and reverse feed mechanisms attached;
  • FIGS. 3A-3D are paired schematic drawings of the opposite ends of the combing head of FIGURE 2 illustrating the successive positions assumed by the forward and reverse feed mechanisms during the forward motion of the nipper frame cycle;
  • FIGS. 3E-3H are paired schematic drawings of the opposite ends of the combing head of FIGURE 2 illustrating the successive positions assumed by the forward and reverse feed mechanisms during the backward motion of the nipper frame cycle.
  • a typical combing head as shown in FIG. 1, includes the nipper frame 2 to which the cushion plate 4 is attached, and on which the nipper knife 6 is pivotally mounted.
  • This frame is carried by two front-suspension links 8 pivoted at a high level on the frame uprights almost directly over the rotary half-lap comb 10.
  • the frame 2 is pivotally supported in the lower ends of these from links by the pivot studs 12 projecting from the sidewalls of the nipper frame.
  • the rear portion of the nipper frame 2 is pivotally connected and thereby supported in the lower ends of a pair of crank arms 14 depending downwardly from a rock shaft 16 and substantially parallel with the front links 8.
  • the nipper knife 6 is carried in two arms 20 and 22 which are pivoted to the nipper frame on the inside of the sidewalls thereof at the point [marked 24.
  • the knife is opened and closed by the swinging movement of the frame by means of two knife actuator studs 26 and 28 which are carried in the front end of the arms 20 and 22.
  • These actuating studs each engage a relatively fixed cam track member 30 and 31 mounted on the frame upright.
  • the cam tracks in these members are designed or shaped so that the forward swing of the nipper frame 2 cams the nipper knife 6 to open position and the backward swing closes it nipping the lap against the cushion plate.
  • a roll of cotton lap to be combed (not shown) is supported on two creel rollers 32 and 34 which are appropriately driven so as to unwind the lap and deliver it over the lap plate 36 to the nipper feed roll 38.
  • the feed roll 38 the lap is delivered to the nipper jaws 4 and 6 of which the lower jaw or cushion plate 4 is fixed on the nipper frame 2.
  • the upper jaw or nipper knife 6 is operated to open and receive the lap fed by the roll 38 and then close upon it and nip it firmly, holding the projecting end thereof in the path of the comb teeth 40 on the rotary half lap comb whereby the forward ends of the lap fi bcrs are combed.
  • the nipper jaws 4 and6 moving forwardly deliver the terminal tuft of the combed fibers to the detaching mechanism 18, opening at the same time so that the tuft may be drawn away from the body of the lap.
  • the detaching mechanism 18 includes a pair of back rollers 42 and 44 which seize the front ends of the fibers delivered by the nipper jaws 4 and 6 and by their forward rotation separate the tuft from the lap still held by the feed roll 38 and pull it through the teeth of a top comb 46 which has been lowered for that purpose.
  • a top comb 46 which has been lowered for that purpose.
  • the detaching rolls 42 and 44 receive the front end of the tuft on the top of the tail end of the preceding tuft, with an appropriate overlap, thus piecing the tufts together to form a continuous fleece. For this purpose the rolls are given an alternate forward and backward rotation.
  • the combination forward and reverse feed mechanism comprises a first and second one-way clutch and clutch housing 50 and 52 respectively attached to each end of the feed roll 38.
  • a pair of turnbuckle links 54 and 56 provided for adjustment connect one end of each of the clutch housings to fixed pivot points, 58 and 60 respectively, located in the arms 20 and 22 which carry the upper nipper jaw 6.
  • FIGS. 3A to 3D and SE to 3H show in paired schematic form the principal positions of the feed mechanisms located at each end of the feed roll during the forward and backward motions of the nipper frame cycle.
  • FIGURE 3A the combing of the end of a tuft issuing from the closed nipper jaws 4 and 6 has just taken place.
  • the rolls 42 and 44 begin a backward rotation reversing a portion of the rear ends of the fibers recently combed by the rotary half-lap comb 10 into a position to be overlapped by the next arriving tuft.
  • the forward swing of the nipper frame 2 cams the actuating studs 26 and 28 carried in the front end of the arms 20 and 22 along the cam track members 30 and 31.
  • This camming movement causes the arms to pivot upwardly opening the nipper knife (FIG. 3C).
  • the upward movement of the arms, 20 and 22 in turn, causes the turnbuckle links 54 and 56 to pull the arms 62 and 64 on the clutch housings 50 and 52 upwardly.
  • the upward pull on the arms on the clutch housings rotates the first or forward feed clutch 52 in lock direction driving the feed roll 38 to feed the lap to the nipper jaws 4 and 6.
  • the upward pull on the arm 62 on the clutch housing of the second or reverse feed clutch 50 causes it to rotate in slip direction (FIG. 3C).
  • the detaching rolls 42 and' 44 now revolve for- Wardly to draw the fibers through the top comb 46.
  • the forward feed clutch 52 continues to rotate in lock direction while the reverse feed clutch 50 continues to rotate in slip direction.
  • the detaching rolls revolve forwardly and the reverse feed clutch 50 continues to rotate in lock direction while the forward feed clutch 52 continues to rotate in slip direction.
  • the detaching rolls 42 and 44 continue to revolve forwardly 16 and the rotary half-lap comb 10 begins to comb the nipper fringe.
  • the combing is completed, the nipper frame begins to move forwardly and the operation is repeated in the manner above described.
  • a nipper knife In a comber having a forward and backward swinging nipper frame carrying a cushion plate and lap-feed roll, a nipper knife, two arms pivotally connected to said nipper frame for supporting said knife and actuating studs which actuate said knife as said nipper frame is swung in alternatively forward and backward directions; the combination of a first drive means connected to one end of said feed-lap roll for advancing a lap to said nipper knife on said forward motion of said nipper frame, second drive means connected to the opposite end of said lap-feed roll for driving said feed-lap roll to advance said lap to said nipper knife on said backward motion of said nipper frame, and means connected to said nipper frame and movable therewith for actuating said first drive means on said forward motion of nipper frame and said second drive means on said backward motion of said nipper frame.
  • said means connected to said nipper frame comprises a pair of adjustable links, one of said adjustable links connecting said first drive means to a fixed pivot point located in one of said arms which carry said nipper knife and the other of said adjustable links connecting said second drive means to a fixed pivot point located in the other of said arms which carry said nipper knife.
  • said first drive means comprises a one-way clutch, said clutch being constructed and arranged to rotate said feed roll in one direction during said forward motion of said nipper frame and slip relative to said roll during said backward motion of said nipper frame and wherein said second drive means comprises a one-way clutch, said clutch being constructed and arranged to slip relative to said roll during said forward motion of said nipper frame and to a drive said roll in said one direction during said backward motion of said nipper frame.
