Role of Supply Hoppers in Feeding Components into a Vibratory Bowl Feeder

The number of components that can be loaded into a vibratory bowl feeder is dependent on their volume and weight. Volume is important when the components are made of rubber or plastic. And if the components are metallic their weight shall be considered to determine the quantity of components to feed.

In case your application requires extra loading capacity, then the preferred choice is to use bigger bowl feeders. You can also opt for auxiliary feeding units such as vibratory supply hoppers or elevators. These auxiliary equipment can increase the loading quantity of your system to a great extent. Moreover, it will make the component feeding an automatic operation, only requiring refilling at specific intervals.

Characteristics of Storage or Supply Hoppers

Storage or supply hoppers are utilized to hold the extra parts for refilling the supply in the bowl whenever required. They are set to operate automatically through a signal provided by a level control switch. This eliminates any chances of an over-supply, or a deficiency of parts in the bowl. Basic characteristics of supply hoppers include:

  • Manufacturing: Also known as stock hoppers, they can be manufactured in various sizes and dimensions. Two basic types of vibratory hoppers that are popularly used are top type and flat type. The flat design is more popular of the two. This is because it offers the added benefit of not increasing the loading height. Secondly, it increases the loading capacity without having to compromise on the required space.
  • Coating: Supply hoppers are provided in stainless steel and mild steel. Hoppers made from mild steel have a coating or lining of Elscinthane PU. This coating is helpful when using metallic components for feeding. As they can make a lot of noise in the hopper.
  • Controlling: Each hopper requires a vibratory controller or regulator for controlling and varying the speed of the hopper. Along with this, a level controller is used for controlling the component level. This is achieved by a level sensor that is mounted on the hopper. The level controller also helps control the start / stop operation. This is necessary to ensure that the quantity of components loaded in the vibratory bowl is always same.

Storage or supply hoppers help in achieving improved functioning and efficiency of the vibratory bowl feeders. Speak to a manufacturer or supplier to choose a suitable hopper for your vibratory bowl feeder.
