Part presentation is an essential component in many manufacturing processes. Part presentation is the automated sorting and orientation of parts for downstream processing or assembly. Over the years, various technologies have been developed to enhance the capabilities of one of the more popular part presentation solutions - sorting conveyors. In this blog post, we will explore some of the latest technologies used to improve the accuracy, speed, and flexibility of sorting conveyors.

1. Computer vision - One of the most significant advancements in sorting conveyor technology is the integration of computer vision systems. These systems use cameras and advanced image processing algorithms to detect and identify parts, allowing for highly accurate and flexible sorting. Computer vision can also be used to check for defects or quality issues, ensuring that only good parts are selected for further processing.

2. Artificial intelligence - Artificial intelligence (AI) is another technology that has been integrated into sorting conveyors. AI algorithms can learn to identify and sort parts based on various criteria, such as size, shape, and color. This technology enables the conveyor system to adapt to changing part characteristics, reducing the need for manual adjustments or programming.

3. Collaborative robots - Collaborative robots, or cobots, are also being used in conjunction with sorting conveyors. These robots can work alongside human operators to perform tasks such as quality inspection or packing, increasing efficiency and reducing the risk of injuries. By integrating cobots with sorting conveyors, manufacturers can automate more complex tasks and improve overall productivity.

4. 3D printing - 3D printing is a relatively new technology that is starting to be used in sorting conveyors. By using 3D printing to create custom end-of-arm tooling or grippers, manufacturers can optimize the sorting process for specific part shapes or sizes. This technology enables the conveyor system to handle a broader range of parts, improving its flexibility and reducing changeover times.

5. IoT connectivity - Finally, many sorting conveyor systems are being equipped with Internet of Things (IoT) connectivity. IoT sensors can monitor the conveyor system's performance, detecting issues such as jams or overloads and alerting operators before problems occur. This technology can help to prevent downtime and improve overall equipment effectiveness.

The latest technology used in sorting conveyors is advancing at a rapid pace, enabling more accurate, flexible, and efficient part sorting. The integration of computer vision, artificial intelligence, collaborative robots, 3D printing, and IoT connectivity is transforming the manufacturing industry and enabling manufacturers to optimize their production processes. As these technologies continue to evolve, we can expect to see even greater improvements in sorting conveyor capabilities and the overall efficiency of manufacturing operations.

Another solution to part presentation is the vibratory bowl.  Vibratory bowls have been used for decades in automated manufacturing to sort and orient parts. A vibratory bowl works by using vibration to move and align parts that are fed into the bowl. The bowl is typically made of stainless steel and contains an internal vibratory motor that produces vibrations in a controlled frequency and amplitude.

When parts are fed into the bowl, they move along a track and into the vibratory bowl. As the bowl vibrates, the parts move around the bowl and begin to orient themselves due to the movement and shape of the bowl. The vibration causes the parts to move up the sides of the bowl, and they eventually reach the top, where they spill over into a collection area.

The design of the bowl and its internal components, such as the track and the shape of the bowl, can be adjusted to optimize the orientation and separation of the parts. For example, the shape of the bowl can be designed to create a spiral or a circular motion, which can help to separate parts of different sizes and shapes.

 The design of a vibratory bowl can have a significant impact on its performance, and there are several factors to consider when designing a vibratory bowl.

1. Determine the part characteristics - The first step in designing a vibratory bowl is to determine the characteristics of the parts that will be sorted. This includes the size, shape, and weight of the parts. The size of the bowl will need to be large enough to hold the required number of parts, and the shape of the bowl will need to be able to accommodate the parts. The weight of the parts will also affect the frequency and amplitude of the vibration required to sort the parts.

2. Choose the bowl shape - Vibratory bowls come in a variety of shapes, including round, square, and rectangular. The choice of bowl shape will depend on the characteristics of the parts being sorted, as well as the desired orientation of the parts. Round bowls are often used for small, lightweight parts, while rectangular bowls are better suited for larger, heavier parts.

3. Determine the vibration frequency and amplitude - The vibration frequency and amplitude of the vibratory bowl are critical to its performance. The frequency of the vibration should be chosen based on the natural frequency of the parts being sorted, and the amplitude of the vibration should be high enough to move the parts, but not so high that they become damaged. The frequency and amplitude of the vibration can be adjusted by changing the size and angle of the vibratory motor.

4. Choose the feeder track - The feeder track is the path that the parts follow as they are fed into the vibratory bowl. The feeder track should be designed to accommodate the size and shape of the parts, as well as the desired orientation of the parts. The feeder track should also be designed to prevent parts from jamming or becoming stuck, which can disrupt the sorting process.

5. Consider additional features - There are several additional features that can be added to a vibratory bowl to improve its performance. These include sound dampening materials to reduce noise, coatings to protect the parts being sorted, and sensors to monitor the sorting process.

Designing a vibratory bowl requires careful consideration of the part characteristics, bowl shape, vibration frequency and amplitude, feeder track, and additional features. By taking these factors into account, you can design a vibratory bowl that will effectively sort and orient parts during automated manufacturing.
