Those who be based on PLC is muti_function automatic lathe design

1 hardware design is the electric control requirement that realizes afore-mentioned lathe, choose Taiwan always the FBS series of grand PLC, model is FBS-40MAT, i/O check the number is 40 a little bit, have inputted at 24 o'clock, outputted at 16 o'clock, its I/O hookup is shown 1 times like the graph. If express,I/O of graph 1PLC input, input distributes a list 1, the watch is shown 2 times. Express address of 1 input signal to distribute a list address of 2 output signal allocates watch Nextpage3.
2 software design controls train of thought to be: Above all, PLC reads the condition set function that takes the switch that dial a code, the act that can use every function place undertakes classified, main program frame uses a pace to be written into the instruction, in every pace according to the function different, call corresponding subprogram, craft of the treatment that finish. According to systematic technology requirement, according to lathe manufacturing technology writes a program. Undertake debugging through spot machine tool, run normal, reliable, safety. 10 kinds of functions can offer an alternative, if functional list expresses 3 to show. Express evacuation of 3 pairs of crocks to expect functional list should dial a switch to show for 0 when: A crock cuts groove first, groove is cut after B crock. Show when the switch that dial a code for 1 when: Crop of A crock line, groove is cut after B crock. Show when the switch that dial a code for 2 when: B crock cuts groove first, groove is cut after A crock. Show when the switch that dial a code for 3 when: A crock crop, b crock is not moved. Later movement with this analogize. Functional selection process calls a subprogram 4, conclusion is based on always what grand PLC place designs is muti_function automatic lathe, moving case is good, can realize treatment a variety of workpiece, the automatic cycle time that processes each work is 4S only, improved manufacturing efficiency and product quality, it is a kind of practical control method.
