A belt feeder transfers small parts onto a conveyor belt, eliminating the need for human labor. There are three basic models: hopper conveyor, vibratory bowl feeder, and linear pan design. Companies should consider capacity, feed rate, and accuracy when choosing a feeder.
A belt feeder is a device used to transfer materials onto a conveyor belt. These units are typically used as part of an assembly line manufacturing system, although they can also be used with a variety of industrial machinery and equipment. Typically, the belt feeder is designed to work with small parts, such as screws, bottle caps, or fasteners. Belt feeders come in a wide range of sizes, making them suitable for many types of industries. The main advantage of this type of machine is that it can automatically release raw materials into an assembly system, eliminating the need for human labor for this task.
Companies can choose from three basic models of belt feeders. One of the most common is the hopper conveyor, which looks like a large bin with an open top. Hoppers are typically designed to operate by gravity, rather than mechanical means. This type of belt feeder is placed above the conveyor and bulk materials are discharged into the top of the hopper. These materials fall from the bottom of the feeder onto the belt, where they are transported for further processing or assembly.
Hopper conveyor belt feeders can range in size from very small to very large. Small units are found in factories, where they may contain lids or washers. Large units are often used outdoors in quarries and construction sites, where they can haul gravel or earth on a gravel conveyor. These machines also play an important role in the processing and transportation of grain in agriculture.
The vibratory bowl feeder serves as an effective tool for applications where materials need to be positioned a certain way on the conveyor. These feeders feature a mechanized vibrating action and are specially designed to feed parts at a predetermined angle or position. This allows nearby assembly equipment and machinery to quickly accept the part and use it to assemble a product.
Another variation of the conveyor feeder is the linear pan design. Like the bowl feeder, these units use a vibratory mechanism to feed parts to a precise location on the conveyor. They are designed to move pieces linearly or parallel to the floor, making them suitable for areas where there is no space to place the feeder above the belt.
When choosing a belt feeder, companies should consider not only the total capacity of the feeder, but also the feed rate per minute. Other important factors include whether the device can position the items accurately as they are fed, or if the parts are simply released randomly. Finally, buyers should consider whether each feed option can be tuned to work with different types of parts or whether it is specifically designed to accommodate only certain types of items.
