Generating Product Movement
Achieving the correct relationship between the vibratory feeder tray and springs isn't quite as simple as it might seem.
An electromagnetic drive will operate at a set frequency.
(Important Note: It is possible to alter the frequency of the drives with an inverter control system; this is discussed further under the Feeder Control Systems section below)
It is important to try and set up the system so that the natural frequency with which the tray would oscillate on the springs matches the frequency of the electromagnetic drive. This will reduce stresses in the feeder tray and encourage product to flow as quickly and efficiently as possible.
The natural frequency of the oscillation is determined by the relationship between the combined total stiffness of the springs in the system and the mass of the feeder tray plus any product in the tray.
As the feeder tray and mass of product is largely determined by the application, and the electromagnetic drive (minus variable controls) will operate at the frequency of the alternating input (e.g. mains supply at 50Hz), the design variable is the springs.
Increasing the number of springs, and the width and thickness of the spring will increase the spring stiffness. The length of the spring is also a factor; longer springs are less stiff.
The main purpose of the feeder tray is to channel the product being fed to where it needs to go.
To achieve this, aside from being shaped to contain the product and prevent spillage, the tray needs to transfer as much of the energy generated by the drive, into the product as possible.
This is achieved by having a rigid feeder tray, which is determined by the design of the tray.
A tray which is not rigid will lead to areas of the tray vibrating at different frequencies, called secondary vibrations. These areas create anomalies in the flow of product, meaning product can slow, stop, or even run backwards.
Feeder Control Systems
As a vibrating feeder is a relatively simple piece of equipment, the control requirements are small.
Once a feeder is set up to perform its intended function, control requirements are usually limited to stop and start.
This type of control is common when the feeder is controlling the flow of product into a process further down the production line.
