High-speed Management Letter Machine Control System Design And Research

Fast facer machine is designed to dispose the letters that puting at will to be orderly lesser pile with a certain benchmark or regular letters current in order to offer a unhindered condition for letter sorting machine. Now, there are only a few developed countries that can produce this system in the world. Our country can't produce but import it. The task of this thesis is to design our own homemade facer machine. At the same time all the components and parts in the system accord with national criterion so as to depress the cost.The system is numerous and jumbled so I just design and calculate on the control system, and the other parts will be finished by other groups.Compaired with cycle single exit control used by some imported equipments, adopting has many advantages. As follows: first, control programe is simple ; second , the cost of control and ration of double are lower : third , letters can't be damaged easily.
