Application:
The customer wanted acurate feed control of plastic film from a roll on a robotic laser cutting machine. He wanted the machine to feed the material, stop at the preset length, have a laser cutter cut the material, which would then be removed by a robot. After completion of that cycle, he wanted to feed additional material and repeat the process till the batch quantity was reached.
Solution:
Connectric provided a system which measured the feed and provided a relay output when the length was reached. A start button sent a signal to the drive to start the process. The length relay output was timed, and the control of the relay output also inhibited count of the feed during the drive slow down period. Thus there was no overshoot of count, each cycle started at 0. The drive provided a signal to the laser cutter which in turn provided a signal to the robot. Once the material was removed, the robot signalled the drive to start again. This cycle was repeated till the batch count was reached. The Connectric system provided a beacon and buzzer, and a relay output to stop the process. The 2 line display showed the length being pulled (with automatic reset to zero), and the number of pieces processed.
