One of the most cost-effective methods for handling materials is using non-powered gravity conveyors. On rollers or skate wheels installed in frames, loads are transported. The name "gravity conveyor" comes from the fact that gravity conveyors are typically inclined in elevation to allow products to flow freely and take advantage of the Earth's gravity. Gravity conveyors are used to move boxes, cartons, and totes with solid, stiff bottoms. The diameters and spacing of roller or skate wheels will vary. A good rule of thumb is that there should always be three rollers or more underneath the box, carton, or tote.

How Does a Gravity Roller Conveyor Work?

A gravity roller conveyor uses the weight of the load to move a product along rollers. Gravity conveyors are one of the most straightforward and cost-effective materials handling systems. They are excellent for distribution centers, manufacturing plants, and warehouses.

Most of the rollers for these conveyor systems have a diameter of 1.5 inches to 1.9 inches. There are sizes of 2.5 inches and 3.5 inches for heavy-duty applications. System configuration and internet shopping are simple processes. Due to their modest weight, you can use them for short- and long-term uses. There are other options for temporary tripod-style stands or permanent floor supports. For corners, you can use roller curve units.

Installation of Gravity Conveyors

Gravity roller conveyors are typically installed on a decline to convey the product downward to the discharge point, with the infeed at the higher point. If installed properly, a gravity conveyor can operate smoothly, safely, and simply with fewer chances of product damage and higher overall performance.

Installation Considerations

Specify conveyor lines for product weights. The gravity conveyor should be configured for certain product weights to maintain peak performance. For instance, a lighter product could require a steeper descent than a heavier product since the heavier weight can travel toward the discharge end with less gravitational force. It could travel too quickly if you loaded the conveyor with a heavy item.

Conveyor length

Like shorter lines, larger lines can enhance speed because the products pick up speed as they move down the conveyor. The combination of this with rollers that keep spinning after a product has passed over them might result in product acceleration.

Check the product size

Along with the weight, the product's size is crucial. A product base should always be in contact with three rollers or more, so getting the roller spacing right is critical.

Type of rollers

Another aspect to consider when building a gravity roller conveyor is the type of roller itself. Skate wheels enable products to move more swiftly than they would on a standard roller. On the other hand, rollers can handle a wider range of items. Because grease-free bearings roll more swiftly than clean bearings, consideration should also be given to the rollers' bearings.

Speed of the conveyor

You can guarantee that the products stay on the conveyor using the end-stop installation. Additional methods of slowing the items include adding retarding plates, roller brakes, or altering the angle. However, if the product travels too slowly, the conveyor slope can be increased to speed up the product's descent. When the conveyor's slope is steeper, the products move more quickly.

Pretesting the conveyor

The conveyor should undergo testing before being put into use; this will guarantee the best possible product flow and take care of any potential safety issues for the personnel and items on the conveyor line.

Gravity Conveyor Applications

Gravity roller conveyors are a very practical and adaptable mode of transportation with many uses. They are the most prevalent type of conveyor in existence. Gravity conveyors have the following uses:

  • Truck loading and unloading
  • Equipment loading and unloading for manufacturing
  • attaching to scales, carriages, or other industrial equipment
  • Within picking regions, conveyance
  • regions for assembly or kitting
  • The goods transportation

Advantages of Gravity Roller Conveyor Systems

Owning a gravity roller conveyor system has many benefits. The advantages of a gravity roller conveyor system are listed below.

Affordability

Gravity roller conveyors are relatively inexpensive because they don't utilize motors. Additionally, most components are made from steel, aluminum, and plastic—frequently available and universal materials.

Flexibility

These systems are flexible, elastic, and can adapt to customer needs. They are often implemented as temporary conveyors and can be transported without real challenges.

Maintenance

Pallet conveyors are made with gravity roller conveyor designs that are simple to maintain. When one element breaks, it only takes a few seconds to snap a replacement into place because they are primarily manufactured out of inexpensive, accessible materials. It's sometimes as simple as removing the damaged piece and putting in the new one, so you won't have to stop working entirely or look for a specialist.

Disadvantages of Gravity Conveyors

  • When products are moved by gravity, they could become harmed.
  • unable to regulate conveyor speed
