P.B.A Industrial Supplies - Construction (General)

General

The construction and assembly of conveyor systems using Scanbelt modular belting is not significantly different from conveyor systems utilizing other belt types. There are, however, certain points which we would like to emphasise. Therefore we have prepared general assembly guidelines, which we hope will be helpful when designing and constructing a conveyor system.

There are 2 diagrams illustrating horizontal conveyor systems.

Diagram 1: relates to short lightly loaded conveyor systems. This type of construction means the belt is tightened and tensioned by adjustment at one or both shafts. This conveyor system can be used in a reversing operation. It is important to be aware of temperature fluctuations when using this type of construction. In the event of low temperatures, the belt will contract significantly. At high temperatures the belt will expand, which could result in poor or even complete lack of engagement with the sprockets on the drive wheels.

Diagram 2: relates to longer and more heavily loaded conveyor systems. This conveyor system cannot be used in a reversing operation. The first support after the drive wheel ensures the best possible engagement. The second support should be located in a position that weight of the belt "sag" between the first and the second support is sufficient to maintain the correct belt tension. This ensures continuous positive engagement from the sprockets on the drive wheel. Another advantage of this type of construction, which features a series of belt supports, is that it is possible to accommodate any belt contraction/expansion by fluctuating the degree of belt "sag" between all other supports.

A = 200-300 mm

B = Min (1000 mm) & Max (10% of centre distance)

C = 0 - 50 mm

D = S25 (Min ø 50mm) & S50 (Min ø 100mm)
