1524788 Automatic control AMP Inc 3 Feb 1977 [23 Feb 1976] 04530/77 Heading G3N [Also in Divisions B3 and H2] A machine automatically produces lengths of wire W1 ... W5 of pre-set lengths. Lengths of wire are manually led from reels 22-30, on to a drum 42, a pressure roller 58a is lowered on to one length of wire W1 to press it against roller 42, a motor 18 is then started to drive roller 42 to run wire Wl a set distance and then motor 18 is stopped. A second pressure roller is lowered on to a second wire and again motor 18 started, the process being repeated until the different lengths of wire (L1- L5), Fig. 8 (not shown) are produced. The start and stop cycles for motor 18 for these lengths of wire are given in Fig. 9 (not shown). The lengths required are manually pre-set by switches (88a .. ... 96d), Fig. 6 (not shown) which feed into a computer (108), Fig. 6A (not shown) which automatically controls the production of the wire lengths including the raising and lowering of the pressure rollers by pneumatic cylinders. Fig. 7 (not shown) gives the motor control circuit. |
