Abstract

861,267. Automatic material feed-control systems. SCHENCK MASCHINENFABRIK G.m.b.H., C. March 2, 1959, No. 7226/59. Class 38 (4). The rate of feed of loose material from a weigh belt feeder is maintained constant by continuous control of the speed of the belt in dependence on deflections due to the weight of the material on the belt, the rate of feed of the material to the weigh belt feeder being varied simultaneously with the speed of the belt. In Fig. 1 loose material is supplied from a belt feeder 12 to a weigh belt feeder 2. A weigh beam 7, deflected in dependence on the weight of material on feeder 2, operates a potentiometer 15 connected to a tachometer generator 14, driven by feeder 2, so that a voltage is produced representative of the rate of feed of material by feeder 2. This voltage controls a servomotor 18 adjusting a variable-speed drive 13 between an electric motor 19 and feeder 2 so that the rate of feed from feeder 2 is automatically maintained at a value determined by the setting of a potentiometer 20. Feeder 12 is also driven from variable-speed drive 13 so that the material is always supplied to feeder 2 at a rate corresponding to the rate of delivery of feeder 2. In a modification (not shown), potentiometer 15 controls the speed of an electric motor driving feeder 2 and a second potentiometer ganged to potentiometer 15 controls the energization of a vibratory feeder supplying feeder 2. In this arrangement variable resistors are provided to match the characteristics of the motor and vibrator.
