When multiple conveyor belts need to operate in synchronized motion, there are several solutions available. Placement of motor and how you choose to connect the belt conveyors are two factors to consider when choosing a solution. We take a closer look at options how to operate two or four belt conveyors together.
Needs assessment leads to the right solution
When designing a belt conveyor, there are many variables to consider. The size, shape and weight of the material to be transported on the conveyor is important. Transport distance, speed and the required accuracy also need to be taken into account. The unique factors in each individual case often lead to unique designs.
It is not entirely unusual to require synchronized and parallel operation of several belt conveyors. The only limit to how this can be solved is the imagination. Naturally, you are always looking for the most efficient and profitable construction.
Synchronized parallel operation using synchronization shaft
In this example, the application required the synchronized operation of two separate belt conveyors. By utilizing two standard end-drive belt conveyors connected by a synchronizing shaft, the solution was implemented in a straightforward manner. The synchronizing shaft allowed both conveyor belts to be powered by a single motor, ensuring seamless synchronization. A solution like this enables parallel transport of materials on two belts, perfectly synchronized.
When two narrower belt conveyors are connected, as shown in the picture below, space between the belts can be utilized for other things. For instance, a gripper can be placed underneath, between the conveyors, to rotate materials. Alternatively, a smaller, short belt conveyor angled at 90° can be mounted on two vertical actuators to push materials away from the original direction of travel.
The space between the conveyors can also be utilized for additional processes, such as milling, engraving, taping, gluing, etc. These operations can be performed on both the top and bottom surfaces of the material at the same time. Moreover, this solution is cost-effective compared to a wider belt conveyor, which might otherwise need to be over 1000 mm wide.

Simple construction for operating four belt conveyors
How do you operate more than two belt conveyors simultaneously? In this example, four conveyors were designed to run together. By choosing centre drive, i.e. placing the motor in the middle, space was maximized at both the input and output ends while also keeping the motor discreetly hidden underneath.
This setup allows for the use of a larger motor capable of driving all four belts. In the application shown below, small aluminium angles have been mounted, supporting a 2 mm thick stainless steel plate. These angles enable precise adjustment of the plate to align perfectly with the height of the conveyor belts, preventing materials from falling between the belts. This cost-effective solution is particularly well-suited for transporting larger materials, such as textiles, fibre cloth, and similar items.
