Pattern controllers are used mostly in packaging lines that require a unique set of glue application guidelines. A hot melt adhesive controller regulates the temperature and volume of glue that is dispensed and also the pattern that is delivered. The pattern of glue is important to ensure consistency, precision and quality. How it works is the pattern controller activates solenoids for the applicator heads in order to create individual adhesive patterns. Universal Systems SE offers two types of pattern controllers for our ProBilt® hot melt systems: Constant Speed and Variable Speed.
Constant Speed
Constant speed pattern controllers are also known as time based. This means that the glue is dispensed consistently between .001 – 9.999 seconds, depending on the time that you set. They are designed to trigger a 24VDC Solenoid Valve and have on the fly program adjustments, so nothing is set in stone. Universal Systems’ constant speed pattern controllers have up to 4 programmable glue pattern events available and up to 9 programs can be stored in memory and remain in memory even after the system is shut down.
Variable Speed
Variable speed pattern controllers come with an encoder and is also known as distance based. This means that the glue can be dispensed in set distances apart from the last application. Universal Systems’ variable speed pattern controllers measure in tenths of inches, trigger a 24VDC Solenoid Valve and the encoder offers 1200 pulses per revolution. There is a low speed cut off and easy to use program adjustments. Like the constant speed controller, the variable speed controller has 4 programmable glue pattern events and 9 programs can be stored in memory and remain in memory even after the system is shut down.
