A flexible feeder is the main feeding mechanism used to solve the automated loading problem of irregular (non-standard) parts. In recent years, as machine-vision technology and industrial robots have continuously developed and become widely adopted in China, the arrival of the flexible vibratory bowl feeder has filled factories with new possibilities for automation.
The criteria that define a good flexible vibratory bowl feeder are: stable operation, high accuracy, fast cycle time, low noise, and maintenance-free performance. Different industries, part sizes, and efficiency requirements demand careful selection work to satisfy each company’s unique needs; only after the specific requirements are understood can the flexible vibratory bowl feeder be guaranteed to provide a reliable solution.

Selection of a flexible vibratory bowl feeder is mainly determined by the size, weight, and shape of your product.

1. Bowl size
   The bowl size is chosen according to the product size and to the number of parts you need to place on the bowl surface at one time. Danikor currently offers seven bowl sizes; the suitable part size for each is as follows:

• U10 / U15 – for tiny components such as electronic elements and mobile-phone or watch parts: part size < 15 mm, part weight < 15 g.

• U20 / U25 – for small metal parts (steel sheets, spring plates, etc.) and medium-small connectors: part size < 30 mm, part weight < 15 g.

• U30 / U40 / U55 – for large, irregular parts such as toy bricks, medical devices, and automotive components: part size < 120 mm, part weight < 50 g.

2. Part shape and orientation
   Part shape and orientation directly influence feeding efficiency. By understanding the required sorting method, we can raise efficiency, eliminate extra steps, and improve the overall running efficiency of the flexible feeding system. Therefore, the bowl must also be selected according to part shape and orientation requirements. Danikor supplies several bowl types—flat, slot, hole-pattern, and dual-pocket—to ensure parts are oriented correctly.

• Slot bowls let parts fall into slots to achieve the required pickup orientation.

• Hole-pattern bowls have large holes in the surface so parts can drop into them and attain the desired orientation.

• Dual-pocket bowls are split into two sections, allowing two different parts to be fed at the same time while reducing the risk of mixing.
  These customized, part-specific bowls enable parts to be vibrated into position quickly for robot pickup.

Before you start purchasing a flexible vibratory bowl feeder, understanding the selection points above will greatly increase the success rate of your project.
