Preventing Production Line Jams At Baked Goods Factory



Production at a large baked goods manufacturer was nearly "toast". The numerous baked goods products used numerous pan sizes. A constant-speed conveyor system caused major headaches with pan jams and inconsistent conveying rates into the bun cooler and bagging lines. The company needed a quick and economical way to smooth out the lumps and implement intelligent control. The conveyor system utilized RS-485 communications, was nowhere near its end-of-life and represented a huge capital investment. Replacement was out of the question.


Luckily, the company’s system integrator had recently learned about Advantechs’ data communication devices. Connecting an optically isolated serial converter from Advantech, a touch panel and PLC was easy. Now, the oven discharge conveyors and de-panning of bread products can be monitored and controlled automatically. The company preserved its legacy equipment investment and increased plant floor productivity at the same time. And, the “dough” is rolling again…
