Facing the issues of labor shortage and increasingly complex product manufacturing, the manufacturing sites of semiconductor, food, automobile and other industries urgently need to realize the ideal temperature control technology without human intervention. In the previous issue, we introduced the high-performance temperature controller NX-HTC, which meets the increasingly stringent temperature control requirements due to the miniaturization and stacking of semiconductors.
In addition to NX-HTC, which can achieve advanced temperature control, Omron can also provide various temperature control technologies and a rich product lineup according to customers' industries and issues, while improving product quality and production efficiency. In this issue, we will introduce 【Temperature Control Unit NX-TC】.
With conventional thermostats, it was difficult to make ideal adjustments without experience and intuition during start-up settings and change adjustments, thereby affecting quality. With NX-TC, you can capture the state changes that affect the quality like a skilled worker, and automatically control the temperature to keep it in the ideal state. Avoid cumbersome start-up and adjustment operations, making the job site easier.
① Even if the workpiece, environment and equipment change, it can continue to produce qualified products
topic
• The PID must be retuned locally due to the environment to which the equipment is shipped
• PID must be adjusted for each workpiece, time consuming for production changeover
*Automatically adjust PID when starting, control the temperature to keep it in an ideal state, and effectively reduce the labor hours of tedious adjustment.
*NX-TC has the "adaptive control" function, which can automatically calculate the ideal PID value at startup and when the temperature is stable. In addition, it can also monitor the temperature control status of the equipment, and automatically adjust the PID value according to changes in the workpiece or equipment to achieve ideal temperature control.
②【Packaging machine】Even if the packaging material is changed, the quality can be guaranteed to be stable
topic
• To reduce plastic use, switch to sustainable packaging materials and reduce the thickness of packaging materials, the temperature control range is reduced, and the incidence of defects is increased
• It takes a lot of time to adjust the temperature when the equipment starts up and when defects occur
* "Temperature controller for packaging machine" can be used to measure the sealing surface temperature
In the past, the distance between the sealing surface and the temperature sensor was too far, and there was an error between the temperature of the sealing surface and the actual controlled temperature. The temperature difference and defect occurrence rate are directly proportional to the packaging speed.
By installing the temperature sensor for the packaging machine closer to the sealing surface, its temperature is closer to the temperature of the sealing surface, thereby minimizing the influence of temperature fluctuations on the surface of the packaging material.
* Automatic filter adjustment function to suppress fluctuations when measuring surface temperature
When using temperature sensors for packaging machines, the temperature of the packaging material itself has a significant influence, and the temperature may fluctuate periodically.
Using the automatic filter adjustment function of NX-TC, this periodic temperature fluctuation can be automatically suppressed to achieve stable temperature control.
③[Molding machine] Reduce temperature fluctuations caused by factors such as cooling water fluctuations,
Maximize production capacity
topic
• With the economic development of emerging countries and the relocation of production bases overseas, the demand related to infrastructure has surged, and production efficiency needs to be improved urgently
• In the context of high speed, temperature fluctuations caused by factors such as material mixing and cooling water must be adjusted on site
• Difficult to produce at high speed while maintaining quality
BEFORE: For high-speed water-cooled extruders, many factors will cause temperature fluctuations. In order to stabilize the quality, the valve must be adjusted repeatedly on site. Even if the cause of the temperature fluctuation is identified, it cannot be suppressed.
AFTER: NX-TC has a "water-cooling output adjustment function" that can suppress temperature fluctuations at the same time and maintain stable performance. It can control temperature fluctuations to a minimum and increase production capacity while maintaining quality.
*Auto tuning (water cooling)
Before placing materials, the cooling characteristics can be grasped by automatic tuning (water cooling), thereby suppressing temperature fluctuations caused by cooling output.
*External interference suppression function (water cooling)
During the production process after placing materials, the water cooling output adjustment function can continuously grasp temperature changes, and automatically adjust the proportional band (cooling) to suppress temperature fluctuations.
Note: The data obtained from the actual measurement of the water-cooled 2-axis extrusion molding machine by our company
Omron temperature control unit NX-TC, with its superior temperature control performance, promotes the upgrading of the food industry and the automobile industry, and contributes to the improvement of productivity.
