Definitions

  • a rotatable ring gear 14 is contained in the knitting bed as shown in Figure 3.
  • the knitting machine frame includes winding frame arms 16 , 17 that rotate synchronously with the ring gear 14 through two connecting rods 15 connected at the bottom of the gearing 14 .
  • the winding frame arms 16 , 17 are formed integral with each other and are fixed on the bottom frame 17' .
  • One of the frame arms 16 is semi-circular in shape to allow the fabric wound into a cylindrical package to be removed in a horizontal direction relative to the machine ( Figure 10).
  • the fabric doffing mechanism includes a doffing plate 49 for pressing the side of the knitted wound fabric on the winding roll 21 .
  • a movable block 50 includes a female screw portion fixed to the doffing plate 49 and integral therewith. Screws 51 mesh with the movable block 50 .
  • a motor 52 drives the screw 51 .
  • Two guide bars 53 are in parallel with the screw 51 and are inserted into support frame members 54 .
  • the movable block 50 is displaceable between support frame members 54 .
  • a sprocket wheel 55 is secured onto one end of the screw 51 beyond the outer side of the support frame 54 .
  • the sprocket wheel is driven by a motor 52 secured to another sprocket wheel 56 through a chain mechanism.
  • the motor 52 is connected to a motor support frame 57 positioned on the side of the support frame 54 .
  • a channel configured cover 58 and angle members 59 are fixed onto the sides of the support frame members 54 at upper and lower portions. Both side ends of the cover 58 and angle members 59 are shielded, such as by resilient rubber plates 60 , positioned above and below the entrance to prevent fibers from entering.
  • the arms 50a on both sides of the movable block 50 extend upward beyond the rubber plate 60 .
  • a vertical plate 50b is fixed on the arms 58 .
  • the doffing plate 49 is connected to the vertical plate 50b and the forward end of the doffing plate extends within the vicinity of the winding roll 21 ( Figure 4).
  • Rotation of the pulley wheel 73 drives pulley wheel 74 and displaces the mounting support block 68 connected to the pulley wire 75 , as well as the movable block 65 .
  • a sensor plate 65c is connected to the side end of the movable member 65 .
  • a contactless switch KS3 detects the positional base point of the movable member 65 .
  • a contactless switch KS4 detects the terminal point of displacement of the member fixed opposite the sensor plate 65c .
  • the gate opening and closing mechanism 76 includes a transmission motor. Below the window portion 80 , pulley wheels 77 are positioned and a pulley wire 78 extends between and around the pulley wheels.
  • a console of the digital panel mechanism 7 comprises a 10-key pad into which preset values and motor speed control values for the knitting machine are input.
  • the digital panel includes function keys, monitors and trouble shooting lamps.
  • a central processing unit (hereinafter referred to as "CPU") (not shown) performs processing in accordance with the pre-input sequence control program.
  • the CPU is positioned in the digital panel 7 .
  • a microswitch KS17 for confirming that the fabric is wound on the winding roll 21 , is connected to the digital panel 7 .
  • the switch KS17 operates when winding of the fabric on the winding roll 21 fails. At that time stop signals are transmitted to the digital panel 7 to stop the motor M connected through the ACI motor control panel 9 , as well as the other mechanisms connected to the auto doffer control panel 10 .
  • the fabric doffing motor is rotated in the reverse direction and the fabric doffing mechanism 47 returns to the initial base position (N step 127 ); otherwise, error is implied and the operator performs checking.
  • the motor for the fabric doffing device 47 is stopped (N step 129 ); otherwise, driving of the motor for the fabric doffing device 47 continues.
  • the motor M1 for opening and closing the gate 12 is stopped.
  • the turning lever 28 is retaining the winding roll, other mechanisms and components are sensed to determine whether they are stopped: the driving part for displacing the cutter; the closure of the gate 12 ; the locking of the winding roll by the locking-unlocking cam 38 ; and whether the fabric doffing device is stopped or performed in base positions. If the above mechanisms are stopped, the knitting machine is started again; otherwise, error is implied, and the operator performs checking.
