Machine for welding steel mesh with adjustable mesh size
This machine has been working since 2013.
The diameter of the mesh rods is from 0.9 mm to 4.5 mm.
The width of the steel mesh is variable, up to 1.3 m, the number of longitudinal rods is variable, now 14 is used.
The length of the steel mesh is variable, it is now used 2.2 m (also a mesh of 6.5 m length was made on request).
A personal computer is used as a PLC. The control program via the LPT and COM ports controls 2 stepper motors, 3 pneumatic cylinders,
8 digital outputs, and uses 9 digital inputs (buttons, switches).
OS - DOS.
Language - PASCAL, LDmicro ladder diagram.
