Title: Automatic Feed Control for High Speed Weighing
IPC: G01G23/18
Filed: 1968-01-22
Abstract: 1,197,040. Automatic feed control. WOODMAN CO. Inc. Jan.22, 1968 [March 17, 1967], No.3306/68. Heading G3R. A hopper is repeatedly filled to a desired weight from a conveyor and then discharged, the time for each filling being compared with a desired time so that any difference causes adjustment of the conveyor feedrate by a fixed amount in a corrective sense. In Fig. 1, a timer 20 periodically operates a bi-stable relay 22 to energize relays 30, 26 so that a gate 16 is opened and a vibrator 65 energized to supply material, e. g. potato chips P, from a conveyor 10 to a weighing hopper 11. When hopper 11 has filled to a desired weight, movement of a flag 13 attached to it influences light from a lamp 14 reaching a photo-cell 15 so that relay 22 is reset to close gate 16 and stop vibrator 65. Some time later, a gate 17 is opened by timer 20 for a period sufficient to transfer the material to a packet. The cycle re-commences at the completion of transfer, or a little before to save time. An adjustable cam 39 rotated once per cycle determines the time at which the hopper should be full. If the hopper fills sooner, operation of relay 30 energizes a self-holding relay 36 to move a switch 49 to its dotted position so that the low portion of the cam operates a servomotor 46 for a fixed period in the appropriate direction reduce the energization of vibrator 65 by adjustment of a potentiometer 63 through gearing 60, 61. If hopper 11 takes longer than desired to fill, self-holding relay 36 is not energized and servomotor 46 rotates in the opposite direction for a fixed period. The rate of feed of conveyor 10 is thus adjusted to tend to maintain a constant weighing time. Direction of operation of servomotor 46 is indicated by neons 55, 56. The adjustment of potentiometer 63 may be manually over-ridden by operation of a knob 66 to overcome a slipping clutch 62 which also allows slip at the limits of adjustment. Gears 60, 61 have a predetermined amount of backlash which may be large enough to prevent adjustment of potentiometer 63 unless at least two successive attempts are made in the same sense.
