In this thesis study, a prototype is designed in order to improve the weighing
accuracy of the weighing and packaging machine that used in sugar factories. The
unavoidable factory conditions cause weighing and packaging machine to do
weighing errors. In order to correct these errors, the prototype produced in this study
was designed as a quality control unit which will take the excess sugar and fill the
deficient sugar in the sacks. Because of being small and having an easy installation,
the application of the prototype was done considering 1-kilogram bags rather than
available 50-kilogram ones.
So as to correct the faulty weighing, sugar extraction and filling processes are
provided from a bunker which is designed on the basis of data obtained by statistical
analysis. For suction, vacuum is used and filling is realized by a ball valve. Upwards
and downwards movement of the bunker is carried out with a pneumatic cylinder.
Weighing information is received via a load cell and an indicator. Control of all these
devices is provided by PLC hardware and SCADA interface.
