Conveyor & Process Control

Customer Ask: Conveyor Line Maintenance

The customer was having problems with the photocells on their conveyor lines. The main problems were dirt accumulation and misalignment of reflectors. The problem was compounded by the need to track a 36″ 200 lb. CRT, as well as a matrix panel which is installed inside the CRT. During production, these two parts are prepared on separate conveyors and then mated together at the end process. Because of the frequent failure rate of the photocells, the customer was experiencing loss of production, increased scrap, and increased maintenance costs.

Application Requirements: 

• A position and presence detection sensor
• A sensor resistant to a hostile environment
• A durable sensor with a high level of reliability and accuracy
• A sensor that can be easily installed
• A sensing range of 5″ to 20″

The Migatron Solution:

One sensor was required to sense the presence of each part on the conveyor, at various stages along the conveyors. A second sensor was needed to position the two parts, as they arrived on separate conveyors, for the final mating process.

We recommended the RPS-401-40, as it meets and exceeds all of the customer’s requirements. The customer was able to use the RPS-401-40 for both the presence detection application and the positioning application.
