RATCHET-TYPE WIRE FEEDING MECHANISM

Click to enlargeClick to enlarge Description

Link 1 rotates about fixed axis A and is connected by turning pair B to link 9 which, in turn, is connected by turning pair C to bell crank 2. Bell crank 2 turns about fixed axis D and is connected by turning pair F to pawl 10 which engages and rotates ratchet wheel 3 intermittently about axis D.• Rotating together with wheel 3 is roll 4. Rolls 4 and 5 are engaged through meshing gears, rigidly attached to the rolls and rotating about fixed axes D and E. As the rolls rotate, wire 12, clamped between them, is fed upward through channel 6. Slide 8 is reciprocated in fixed guide b by cam 11 which is rigidly attached to link 1. In the upstroke of slide 8, knife 7 cuts off piece a of the wire. The length cut off depends on the angle of rotation of ratchet wheel 3 to each stroke of pawl 10.
