DEVICE FOR WEIGHING AUTOTRANSPORT Russian patent published in 1995 - IPC

FIELD: weighing equipment. SUBSTANCE: device has two force-measuring transducers disposed under weight-receiving unit at the axis being perpendicular to axis of motion of automatic transportation facility. Device also has converting unit and registration unit. Converting unit has two channels and unit for determining moments of start and finish of weighing, as well as commutation unit. Each channel of converting unit is made in form of mating unit connected in series with analog-to-digital converter and linerizer. Unit for determining start and finish moments of weighing has pulse generator and four AND circuits 15-18. Output of pulse generator is connected with the first input of the first AND circuit 15. The second inverting input of circuit 15 is connected with output of AND circuit 16. Inputs of circuit 16 as well as inputs of AND circuit 17 are connected with inverse and direct outputs of pulse counter 14. C-input, R-input and L-input of the pulse counter are connected to outputs of the first AND circuit, the third AND circuit and outputs of mating units. Mating units are connected to the first input of the fourth AND circuit 18. Circuit 18 has the second input to be connected with output of the second AND circuit, and output is connected with input of start weighing moment of commutation unit. Input of finish moment of the commutation unit is connected with output of the third AND gate. Outputs are connected to corresponding inputs of registration unit. EFFECT: high precision of weighing; improved reliability. 2 dwg
