No.5 Drying the epoxy resin

Drying the epoxy resin

[ Problem Point ]

There was no heater controller that could heat intermittently
Even when there was no work, the heater was operating and power was wasted.
Also, when the line stopped, cracks occurred in the dry part.
And when it was restarted, there were cases where unprocessed products were generated due to forgetting to turn on the switch.

[ ⇒Kaizen Point ]

Using a speed proportional controller
Since the work is detected by the photoelectric switch, intermittent heating is possible.
Feedback control was also possible with a radiation thermometer.
When the line is stopped, heating is automatically stopped, and when it is in operation, heating is restarted.
Automatically follows speed fluctuations, increasing yield.
