Escapements are mechanical devices that release one part at a time from a bulk supply to regulate the controlled release of individual parts or components. The primary purpose of a part escapement is to ensure that parts are presented in a controlled and sequential manner to downstream processes or assembly stations. This device helps prevent jams, collisions, and misalignment of parts, thus contributing to the efficient and precise operation of the assembly line. They are commonly used in combination with other feeding methods, like at the end of a linear track as parts exit a vibratory bowl feeder.
Hopper systems can hold a bulk supply of parts, and conveyor belts or vibratory conveyors can transport the parts to the automated machine. Sensors and control systems can be used to regulate the flow of parts and ensure a consistent feed rate.
- A large ground hopper with an elevated conveyor is commonly used in situations where an operator needs to load bulk parts at an ergonomically efficient height and then those parts need to be carried upwards into an automated machine. They are often used in various industrial and material handling applications to store, dispense, or feed materials, such as granular solids, powders, or bulk items, into downstream processes, machines, or conveyors.
Robotic arms equipped with specialized end-effectors can pick parts from a bulk supply and precisely place them into the machine. Vision systems can be used for part recognition and alignment.
- Pick-and-place robots are commonly used in conjunction with Flex Feeders. A flex feeder is a type of automated part feeding system used in manufacturing and assembly processes. The primary purpose of a flex feeder is to feed a variety of parts or components into an automated assembly or manufacturing system without requiring extensive retooling or changeover when switching between different parts. This flexibility makes them suitable for applications with high product variability or frequent product changes. They are also particularly useful for feeding parts that have unique geometries or may get tangled or caught on each other in other traditional feeding systems.
- Bellco has a complete line of Flex Feeders, suitable to fit a wide variety of part sizes and applications. Flex Feeders are designed to gently vibrate parts on a flat surface to scatter and move them around so that a vision system can tell the robot where to pick.
Conveyors play a crucial role in manufacturing, facilitating the movement of materials, components, and finished products throughout the production process. They help enhance efficiency, reduce manual labor, and ensure a smooth, continuous flow of materials. Conveyors are used in a wide range of applications within manufacturing, including:
