Feeding System

A feeding system, comprising:

• a hopper having a discharge port at a bottom of the hopper, the hopper being configured to accommodate a plurality of different types of product components, each of the product components adapted to flow out from the discharge port of the hopper by a weight of the product component;
• a flow control gate disposed at the discharge port of the hopper, a flow rate of the product components flowing out from the discharge port of the hopper is adjustable by adjusting an opening degree of the flow control gate;
• a sliding rail having an upper end at a high position and a lower end at a low position, the sliding rail being obliquely disposed below the hopper with respect to a horizontal plane and being configured to receive the product components flowing out from the discharge port of the hopper;
• and
• a vibration excitation unit disposed at the lower end of the sliding rail and receiving the product components that slide off the lower end of the sliding rail, the vibration excitation unit configured to separate the product components and to change a posture of the product components by virtue of vibration.
