How does a Currency Counting Machine Work?

            If you have lately visited a bank, you must have noticed that the currency notes are counted by a machine instead of the counter clerk. Almost all banks in the world now use currency counting machines for counting and packing notes in denominations of hundreds. Job of counting and packing is done manually by a large number of people, which is a boring and tiring job. To eradicate this problem, scientists have developed a machine, which automatically counts and packs currency notes.

            The bundle of notes to be counted is placed o platform P-1. A feeding roller R-1 pushes these notes forward. A sensor S-1 counts these notes. Thereafter, the notes pass through the rollers R-2 and R-3, and channel C-1. Through the channel, the notes reach the sensor S-2. In case of any error in counting, S-2 will shut the motor automatically and display the error. After sensor S-2, rollers R-4 and R-5 pick up the notes and throw them into the slots of the centrifuge roller. These notes are released as they reach the platform P-2 and start stacking upon it. This platform is equipped with another sensor S-3 that indicates whether P-2 is empty or loaded.

            Currency counting machine is a microprocessor-based machine and hence its reliability is very high. Similar machines can count currency notes and coins. These are portable machines and can be installed anywhere.
