It's just not the general public that sends out mail to be delivered to the local post box or office. The post is also a primary means of communication for big corporations. In these times of global competition, it is important that postal processes such as receipt, sorting, and accurate delivery of mail are as streamlined as possible to keep business moving efficiently. The organization of this vital stream of mail and packages into city, post box, house number, street number, etc., which in turn will be delivered accurately to the recipient, is carried out by the mail sorting machines. Mail sorting machines rapidly sort out every piece in the correct order so that punctual delivery is assured. These sorting machines are used not only by postal departments, but also by big corporations to presort their mail before it's sent out for delivery. Mail sorting machines can be used to sort outgoing mail, but can also be employed to sort incoming mail by receiving department or individual. Automated sorting machines drastically reduce the amount of manual time spent over sorting letters, and increase the accuracy of the sorting through recognition of mail address and postal barcodes.
Mail sorting machines consist of mechanical elements (such as a conveyer belt), electrical elements (such as motors, switches, and control boxes), optical elements (such as bar code scanners and character recognition), software, electromechanical elements (such as electric motors and pneumatic linear actuators), and electronic components.
There are various parameters involved in the operation of letter sorting machines including torque speed, power supply voltage, reversibility, duty cycle, and more. Motors in any sorting machine should generate enough torque for any type of load. The maximum speed motors can reach is determined by the torque speed curve, where the load is driven at a constant speed by using DC motors or by stepper motors. For sorting machines that have incremental motion and angular positioning at discrete locations, stepper motors are an ideal component. Stepper motors can be rotated very easily and can be held at discrete positions. Stepper motors can also rotate at different speeds by predetermining the step rate of the motors. Stepper motors can also be operated with an open loop control where no feedback is needed, or in machines that need feedback, an encoder can be included with the stepper motors to check if the motor in the sorting machine has achieved its desired positioning. Stepper motors are ideal for complex and precision motion requirements of the letter sorting machines. DC motors can also be used for adjustable speed operations.
