Inline Seam Control (ISC)
Billions of cans checked...
The inline seam control (ISC) system is designed to control the seam quality in canning facilities. It uses the analog signal from load cells measuring the force during the second operation of the seaming process. The system detects seaming problems at the typical maximum food production speed of 20 cans per second with the systems computing power being sufficient for high speed beverage canning as well. It provides an efficient method to detect problems like lid in the seamer, pillar/letter box and product in between of lid and can. A kicker signal for faulty cans is generated, an optional tracking/rejection system is available on request. Depending on the product related main problem cause return of investment can be typically achieved within 6 month of production[download ISC Flyer]
ISC provides efficient means to detect and reject cans with the following defect classes:
In addition following machine settings and problems are recognised:
The complete system consists of a modified cam with load cells and the ISC mother board interfaced to a touch screen panel PC. A graphical user interface allows the user to control and parametrise the system.
Recent installations comprise full can tracking in conjunction with pneumatic pushers without the need for additional external PLC hardware.
