Choosing the right pitch for your bowl
While designing a bowl feeder, deciding upon the track width of the bowl is very important for the proper orientation and speed of the components. If the track is too wide with respect to the component size, then all the components would come up widthwise while in case the track width is too less, most of the components would fall off the track, back into the bowl. Hence, the track width is most important in cases where the orientation is critical and secondly where the speed or feed rate required is high. Further, in case the track width is too large, the bowl (especially in case of step or cascade bowls), would become too big and wont function properly. While in case of cylindrical bowls, in case of large track width, the loading space for the parts reduces, increasing the jamming of components, which is the hall mark of cylindrical bowls. Hence, a proper balance has to be stuck between the two, depending upon the component size. Quite a lot of small bowl feeder manufacturers do not understand the importance of having the correct track width and this results in their bowl feeders not orienting the parts or reduced feed rates most of the times. Further many small bowl feeder manufacturers have standard bowls with standard track widths which they use for all applications, irrespective of the component dimensions. This reduces their cost and time, but results in the customer suffering with lower feed rates. Hence, it is always better to purchase bowl feeders from established and reputed companies like Elscint Automation, which have the correct technology and skills to plan and design a bowl having the correct pitch for a particular component.
