I increasingly see the figure of automatic beverage bottle recycling machines around me. They not only provide us with a convenient way to recycle beverage bottles, but also play an important role in promoting resource recycling and reducing environmental pollution. However, there is a key issue that needs to be addressed in these automatic recycling machines:

How to accurately detect whether the beverage bottles in the recycling box have reached a specific height to prevent overflow?

The Meiji Sensing EST photoelectric sensor series provides strong support for the smooth operation of smart beverage recycling machines with its transparent object detection capability and superior performance.

In this issue, Xiaoming will share with you the application of transparent detection photoelectric sensors on smart beverage recycling machines.

Scenario requirements

In the automatic beverage bottle recycling machine, when the number of beverage bottles in the recycling box reaches a certain level, the machine needs to stop receiving new bottles to prevent overflow.

This requires the addition of a sensor that can accurately detect whether the bottles in the recycling box have reached the designated position.

Request to check if the recycling box bottles are full. If they are full, the module unloading mechanism will move to another recycling box. When both recycling box bottles are full and output a signal, the device will prompt that the material is full.

Difficulty analysis:

There are various types and sizes of beverage bottles, as well as transparent plastic bottles. As most beverage bottles are transparent, traditional photoelectric sensors may fail due to the inability to capture sufficient changes in light signals.

Select the EST series photoelectric sensor specially designed for transparent object detection by Akusense, which adopts the principle of retro reflection and zero blind spots; The detection distance is up to 2 meters; 0.5ms response speed; Can stably detect the accumulation height of bottles without exceeding the limit, preventing bottle overflow

🔺  Regression detection principle: a powerful tool for stable detection of transparent objects

Traditional photoelectric sensors often struggle to accurately detect transparent or semi transparent objects. This is because transparent objects have strong transparency to light, making it difficult for sensors to capture sufficient changes in light signals to determine the presence of objects.

However, the Meiji EST-X200 sensor adopts the principle of regression detection, detecting objects by emitting and receiving light beams along the same path. When the light beam is blocked by an object, the sensor will receive a signal change to determine the presence of the object. This principle enables the EST-X200 sensor to stably detect transparent objects, even if they are transparent beverage bottles.

🔺  Zero blind spots: Ensure accurate detection and prevent overflow

In the automatic beverage bottle recycling machine, the blind spot of the sensor is a problem that requires special attention. If there is a blind spot in the sensor, the sensor may not be able to detect the presence of beverage bottles when they pile up to a certain height but have not yet touched the area outside the blind spot. This will lead to an increase in the number of beverage bottles in the recycling bin, which may eventually overflow.

However, the Akusense EST-X200 sensor achieves zero blind spot detection through its unique design. This means that no matter where the beverage bottles are stacked, the sensor can accurately detect them and stop receiving new bottles in a timely manner to prevent overflow.

🔺  Long detection distance: up to 2 meters, suitable for various scenarios

The detection distance of this sensor is up to 2 meters, which means it can accurately detect the presence of beverage bottles at a longer distance.

This feature enables the EST-X200 sensor to adapt to various scenarios, whether it is a large beverage bottle automatic recycling machine or a small recycling bin, it can easily handle them.

🔺 Fast response time: only 0.5ms, improving user experience

The response speed of sensors is also crucial in automatic beverage bottle recycling machines. If the sensor response speed is too slow, when the beverage bottles pile up to a certain height, the machine may not be able to stop receiving new bottles in time, resulting in overflow.

However, the response speed of the Akusense EST-X200 sensor is very fast, only 0.5 milliseconds. This means that when the sensor detects a beverage bottle, the machine can immediately stop receiving new bottles to avoid overflow. This feature not only enhances the user experience, but also reduces the machine's failure rate.

🔺  Application effect: Improve user experience and reduce operating costs

After applying the Akusense EST-X200 photoelectric sensor in the automatic beverage bottle recycling machine, its effect is obvious.

Firstly, the sensor can accurately detect the number of beverage bottles in the recycling bin. When the quantity reaches the preset threshold, the machine will automatically stop receiving new bottles. This not only prevents bottle overflow, but also improves the automation level and user experience of the machine.

Secondly, due to the high stability and reliability of sensors, they can operate stably for a long time, reducing the frequency of maintenance and replacement and lowering operating costs.
