Title: Apparatus for continuously conveying and weighing-out amounts of loose material or the like which are constant per unit of time
IPC: G05D7/06
Filed: 1952-01-21
Abstract: 736,345. Automatic feed weighing systems. SCHENCK MASCHINENFABRIK GES., C., [formerly SCHENCK MASCHINENFABRIK DARMSTADT GES., C.]. Jan. 21, 1952 [June 23, 1951], No. 13281/54. Divided out of 736,298. Class 38 (4). [Also in Group XXXVIII] Constant feed rate.-A feed control weighing belt 1 is driven by an electric motor M, supplied by three-phase grid controlled rectifiers 28, to maintain a constant rate of feed. The grid circuit phase-shifter 35 is controlled by a comparator in accordance with the difference between the motor armature voltage and a preset reference voltage from a control panel 36 fed from the motor-field-supply-rectifiers 32. Constant weight.-Variations in the bulk weight of the material, cause deflections of the weigh-beam to vary a resistance 12 in the field-circuit of the motor M, thereby varying the rate of feed to maintain constant weight delivered per unit time. The variable resistance 12 may comprise a mercury switch connected to a tapped resistor, Fig. 2 (not shown). Alternatively the weigh-beam may vary the setting of the phase-shifter 35 to control the armature voltage instead of the field. The Specification states that a variable inductance, capacitor, photo-electric or piezo-electric transmitter may be used instead of resistance 12 to detect variations in bulk-weight. Indication.-As shown, voltmeters 172 18 responsive to the armature voltage (i.e. rate of feed) may be calibrated to show the weight delivered. If the weigh-beam acts on phaseshifter to vary the armature voltage the meters 171, 181 are fed from the field supply through a potentiometer linked to the rate-setting-control on the panel 36.
