Interroll offers a wide variety of tapered rollers for roller conveyor curves.
The details of a roller conveyor curve can have a great impact on the flow of materials. The disadvantages of conventional tapered rollers are particularly noticeable at higher speeds or when roller conveyors that have not been optimally designed and installed are used to convey materials other than those intended.
As with cylindrical rollers, the material being conveyed begins to move outward at speeds of around 0.8m/s, because the centrifugal force becomes greater than the frictional force. The material being conveyed then exerts a counter-force on the tapered elements in the direction of the inside of the curve. Over time, this increases the risk that the tapered elements will move. Gaps can appear between the elements or contact can be made with drive elements, such as the Poly V belt, causing damage.
If the tapered elements are locked from the outside, interfering points or edges will appear, which have a tendency to collect parcel string, adhesive tape and other debris, and can even damage packaging and make smooth transport impossible.
The varying diameters of tapered rollers have two effects: varying roller speeds, which results in the conveyed material being transported through the center of the curve, and friction, which creates a static charge. If it is not possible to correctly earth all of the components, this could lead to quick electrostatic discharge. This can be unpleasant for users and can also be a risk to delicate conveyed material or the electronics inside the conveyor system itself. Interroll therefore recommends that roller conveyor curves are always earthed.
As part of its continuous product optimisation, Interroll has developed an innovative solution: the tapered elements are secured from the inside, which prevents them from moving. This has the advantage of not being visible to users.
In addition to fixing the tapered elements, their material has also been improved. The grey and black tapered elements can be used in temperatures as low as -28°C, and the black elements also possess anti-static properties.
Interroll’s new tapered rollers are reliable and ensure problem-free conveying. They are now available in the European market and will be launched in Asia and the US later.
This innovative solution is available for all RollerDrive series and the 1700 KXO and 3500 KXO roller series. This means that all tapered elements based on a diameter of 50mm are available at 1.8° in grey and black, and at 2.2° in grey.
