Loopless Stacked Spiral Conveyor
With the trend for warehouses and production lines better utilize overhead space, products sometimes need to be transported to considerable heights, even beyond the limitations of a single Spiral Conveyor. This is where the Stacked Spiral Conveyor comes in handy. It can transport products up to greater heights. The concept of stacking Spiral Conveyors on top of each other to gain more elevation height is a well-proven and reliable concept..
To connect two stacked Spirals, a monorail conveyor is required to loop from the outfeed of the lower Spiral to infeed of the higher Spiral. This solution requires a little extra space. In our new design, the infeed and outfeed of the connecting stacked Spiral are joined directly together without the need for loops. The return box is located beside to the turns to avoid interference with machinery parts. This principle allows multiple Spiral Conveyors to be connected infinitely. This design can work for all single lane Spiral Conveyor models.
Main advantages
Space and cost
Our new design addresses the space requirements for stacking. It is based on the same reliable design principle as our standard Spiral Conveyor, but eliminates the need for additional loops in between Spiral Conveyors. (See figure 1.) Therefore, it is more economical both in terms of space and investment.
Efficiency
The transfer sections between the Stacked Spiral Conveyors are at an incline to reduce the number of turns in the spiral set. By keeping these sections inclined – including (driven) transfer rollers, we have achieved a very smooth transfer of products from one Spiral Conveyor into the other.
Reliability and robustness
The design is engineered with a straight segment at all transfer sections to ensure that no internal and radial forces are applied on the sprocket wheel, bearings, poly rail, and other machinery parts. (See figure 2.) This ensures a low wear ratio and results in the highest possible lifetime of all components in the machine.
