In order to meet the requirements of high precision, fast response, stability, reliability, adaptability, and ease of maintenance and upgrade, advanced sensor technology, control technology, and software algorithms are needed to achieve precise positioning and rapid correction of medication bags.

In this issue, Xiao Ming will share the application of AKUSENSE's medication bag correction sensor in the drug packaging machine.

Scenario requirement - medication bag transport correction

Accurate transportation of packaging bags is crucial for ensuring product quality and production efficiency in pharmaceutical production; Therefore, sensors need to be installed during the transportation of packaging in the bag making machine to detect in real-time whether the packaging bag is displaced when it moves, so that the equipment can make timely and accurate corrective actions.

Testing difficulties:

1. There are many types of pharmaceutical packaging bags, and occasionally there may be frosted transparent materials in the packaging bags

2. Due to the fact that the material, size, and transport speed of the medicine bag may vary depending on the product, the system needs to have a certain degree of adaptability to meet different production needs. Therefore, it is required that the detection area cover a range of 8mm or more

3. Unconditionally install the upper computer/touch screen on site, requiring the sensor to come with a controller for easy use

solution

The Meiji Precision Laser Correction Sensor ETD-0612 series is selected and installed on the side of the transport bag, using optical principles for high-precision detection of position and deviation.

It emits light signals onto the surface of the packaging bag and receives the reflected light signals, converting them into electrical signals for analysis and processing. When the packaging bag deviates, the path of reflected light will change, causing a change in the intensity or phase of the light signal received by the sensor, thereby triggering the correction mechanism.

The key tool to ensure accurate and error free transmission of packaging bags

1. Micron level high precision:

The ETD series correction sensor is selected, which adopts the principle of laser alignment detection and has high resolution and accuracy, enabling precise measurement of the position and deviation of packaging bags. For packaging bags made of frosted transparent material, optimizing the design of the light source and detector can ensure accurate detection even in complex optical environments.

The detection area covers a range of 12mm, which is sufficient to cover the size changes of most pharmaceutical packaging bags, ensuring the comprehensiveness and accuracy of the detection.

2. Non contact measurement:

Adopting non-contact measurement principle, it will not cause any damage or contamination to the packaging bag. This is particularly important for pharmaceutical packaging bags, as any form of damage or contamination can affect the quality and safety of drugs.

3. 1ms rapid response:

Fast response speed, capable of real-time monitoring of changes in the position of packaging bags and making quick adjustments. This feature is particularly important on high-speed transmission production lines, as it can significantly reduce production interruptions and equipment downtime caused by offset.

4. Easy to integrate and debug:

Paired with CR-M02 controller, it comes with a high-definition color controller and does not require the installation of an upper computer, making it convenient for on-site engineers to adjust;

Supports 485 to EtherCat network communication, making it easy for engineers to customize and optimize according to actual needs

5. High stability:

The ETD precision laser correction sensor has stable performance under different environmental conditions and has good adaptability to factors such as light intensity and temperature changes. This ensures that sensors can work stably and reliably in pharmaceutical production environments, regardless of high temperature, high humidity, or other complex conditions.
