Belt
Conveyors
|
|
Belt
conveyors are generally used on assembly/packing lines, or
in clean areas such as the food and the pharmaceutical industries.
Belt conveyors will utilise either PVC / PU (smooth or gripped),
Rubber or Modular depending on the application.
|
Belt systems can either be fixed speed or variable speed.
Variable speed units use a speed controller called an inverter
(please note that where variable speed units are used, the
nominal speed can be increased and decreased by approximately
35%), most fixed and variable speed systems can be run on
both 3 phase or single phase.
The
drive will be either:- an externally mounted shaft driven
motor (for heavier or long distance loads), or a motorised
drive drum (a fairly recent development in materials handling
solutions) where the motor is self contained within the
leading roller. For single direction the construction will
usually be end drive tail tension, and for reversible systems
the construction will be centre drive and tension.

Typically they directly convey individual products prior to
packing/packaging. Normally belt systems run from 7m/min up
to approximately 30m/min. Depending on the design. Loads of
up to 100KG can be accommodated.
The
Mobility Tracking Belt Conveyor (images below) is built to the
most modular of designs, and arrives at the client with either
a single or three phase plug (depending on the physical length)
ready for immediate usage. The Unique selling proposition
of the tracker is it's tracking strip profiles on the underside
of the belt, which eliminates the problem of endless tracking
difficulties.
To
meet the demands of growing sectors, and as part of our standardisation
plans we have now developed the stainless steel tracker conveyor,
to be used mainly in the food industry or in situations where
there is water or a moist atmosphere. Motorised drum, frames
and supports are in stainless steel, so too are the optional
guides.

General
Belt Conveyor Configurations
|
| Belt
Width: |
Standard
sizes are from 100mm to 1200mm, although most lengths
can be achieved |
| Module
Length: |
Typically
1m to 6m (shippable, complete with drive and controls),
any longer length will be achieved via coupling conveyors
together, but will need installing |
| Drive
Type: |
1)
Drive drum, 2) External (shaft mounted) motor, or 3) Centrally
underslung |
| Belt
Type: |
PVC,
PU, Rubber, Flighted, Modular |
| Speed: |
Range
from 3m/min to 40m/min, but speeds can be variable (ie,
+/-35%) via an inverter |
|

In
addition to standard horizontal and incline belt conveyors
Mobility also offer bespoke systems including spiral conveyors
for accumulating, cooling down or space saving operations.
Photographs below illustrate the types of systems previously
supplied. One of the main advantages of the spiral system
is that although the operation is declining there may not
be the need for flights as each level is at a slight angle
(this depends on the nature of the product and the friction
between surfaces). The maximum belt width for a spiral turn
is 300mm, but for wider products separate belts will be used
together to create wider systems.
