NX-series Temperature Control Unit
Published on : Tuesday 30-11--0001
Optimal and automatic temperature control without human intervention easily achieves both productivity and quality.
Previous temperature controllers have not only required a long time for start-up settings and variation adjustments, it has also been difficult to make the optimal adjustments without having experience and intuition. There were therefore some effects on quality.
In response to this situation, OMRON developed temperature controllers that includes "adaptive control technology."
This makes it possible to detect the changes in the status which will have an effect on quality and to automatically control the temperature so that the optimal state is always maintained, in the same way as a skilled worker would.
This frees production sites from troublesome start-up and adjustment work.
The answer was the industry's first inclusion* of "adaptive control technology"
With the "adaptive control" incorporated into this product, the optimal PID value is calculated automatically for both the time of the start-up and for during stable production. Furthermore, it is possible to monitor the temperature control status of the machine to automatically adjust the PID value to obtain the optimal temperature control in response to changes such as workpiece changes and machine changes.
E5 D/NX-TC solve the issues
The temperature of the sealing surface is stably controlled automatically with measurement of the sealing surface temperature and algorithms to suppress variations.
Even if the speed of the packaging process is increased, the difference between the sealing temperature and the control temperature is minimized to perform stable automatic control, so it is possible to realize faster production while maintaining the product quality.
This also contributes to the use of thinner packaging materials and to high precision control.
Even with the production of multiple products that require changes to the settings, automatic control reduces the work
Even in the production of multiple products, which hinders faster speeds because a change of packaging materials can mean that time is required to change the settings, the use of automatic control that has a small error in the sealing temperature enables a speedy response at production sites.
Control performance that achieves new value
The temperature error is minimized with a temperature sensor for packaging machines* and an algorithm for packaging machines (automatic filter adjustment function)
"Temperature sensors for packaging machines" to measure the temperature of the sealing surface
The temperature of the heating bar surface is measured accurately and there is no effect from factors causing temperature variations, such as the speed of the packaging machine and changes to the packaging materials.
"Automatic filter adjustment function" to suppress the instability in surface temperature measurements
By using the temperature sensor for packaging machines and the automatic filter adjustment function, it becomes possible to control the quality with the sealing temperature while also suppressing variation in the temperature with just a temperature controller, without relying on adjustments by workers.
New value that supports advances in molding machines] Stable control of the temperature changes arising from faster speeds is performed automatically to realize molding machines that can maximize production capacity.
Issues at production sites
· Increased productivity to respond to demand expansion related to infrastructure as a result of the economic development of the emerging nations and the transfer of production bases overseas.
· At higher speeds, adjustments by the workers become necessary to respond to temperature variations arising due to factors such as the materials compounding and cooling water…
· It is difficult to achieve high speed production while also maintaining the quality..
