Pattern controllers come on the packaging lines themselves and not typically with a hot melt application system. But, while it is not something that many hot melt manufacturers make, it is very important to the glue application process.
Pattern controllers are used for specific glue applications and patterns. The latest pattern controllers have 4 channel controller capability to do both time and distance-based application programming. They can store up to 9 programs and have the capability of operating in “stitch mode” for substantial glue savings. Another unique feature is the low speed cutoff in distance mode to keep the glue off the side guides when the machine is slowed.
So, when do you need to use a pattern controller and which options do you need? Below are the definitions of both constant speed and variable speed controllers to help you figure out which option is best for your application process.
Constant speed pattern controllers are also known as time-based controllers. 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. Most 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 pattern controllers come with an encoder and are also known as distance-based. This means that the glue can be dispensed in set distances apart from the last application. 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.
There is also a hybrid version pattern controller that allows you to do both constant speed and variable speed.
