LoginConveyor Transfers Application Guide
How to avoid snags, box tumbling, & hang-up's
Transfers are used to move a package from one conveyor to another. Straight transfers are the most common type, used to connect individual conveyors in a longer line. Typically, these conveyors can be utilized in straight transfer applications:
- Live Roller to Live Roller
- Live Roller to Belt
- Belt to Live Roller
- Belt to Belt
These kinds of transfers are the least troublesome, but some precautions should be taken with them.
Some of the more common issues are listed below:
Small packages may hang up or tumble when transitioning from belt to belt, at the gap between the two conveyors. The larger the pulley, the wider the gap. A smaller pulley might or a nose bar might be required to address this issue.
Small boxes may hang up on un-powered system and pop-out rollers.
Live roller conveyors provide the best transition since it's possible to power the end rollers with o-rings.
During installation, it must be assumed that both conveyors are at the same level to insure a smooth transfer from one to another.
It's possible to speed up one conveyor to pull a gap or provide separation between cartons. Separation might be necessary for sortation, stops/transfers, box counting, or to separate prior to a curve or incline.
When transferring a package from a power conveyor to a gravity curve, a straight section of gravity conveyor at least as long as the longest package to be conveyed should precede the curve. This is recommended because the force of the belt may be greater than the the force of the curve, resulting in the package overshooting the curve.
Power curves should also be preceded by a straight section of powered roller conveyor as long as the longest box. If boxes jam, it may be necessary to speed up the curve to compensate.
