Roller Conveyors

Lineshaft Powered Roller
Conveyors are purposely used when
situations require either the simple conveying of products
or back to back accumulation, but with as little pressure
on the leading product as possible (although, depending
on the exact application, they can easily be adapted to
become zero pressure accumulation systems).
The
lineshaft is the more light duty of the powered roller
conveyors, handling products that are typically around
25/30Kg, such as cardboard boxes, plastic tote boxes etc.
Typical scenarios for the use of this type of conveyor
are:- order picking lines/stations, production lines,
packaging lines, barcoding sortation systems and obviously
the simple movement of products from A to B.
Lineshaft
Conveyors provide an economical solution to conveying
and accumulating items with a firm base. The rollers are
powered from a drive shaft - mounted beneath the rollers
and extending the full length of the conveying bed - and
are driven via elastomer belts.
Accumulation
occurs via the design of the system, a shaft which is
driven by an external motor doesn't drive the belts directly,
but turns inside a nylon spool. The rollers themselves
are driven via elastomer belts. By stopping the package
on the roller the spool stops. This type of system is
generally used in such places where final production stages
require the packaging of products into cardboard / tote
boxes. Therefore lineshaft powered roller conveyors are
generally sought in warehousing / packaging environments.

Lineshaft
Drive Sections:-
Drive
sections are 500mm long and are fully assembled with
frames, cross ties, shaft etc. with the addition of
a geared motor, mountings, timing belt drive and guard,
complete with rollers. A 0.75kw geared motors will
offer fixed speeds of 5m/min, 9m/min, 12m/min, 16m/min,
20m/min, 25m/min and 30m/min.

Roller
Straights:- The roller section will be 50mm outside
diameter x 1.5mm parallel tube. Grooves will be used
for drive belt operation, with all rollers having
anti static properties. Rollers will be fitted with
dust tight, grease packed bearings together with hexagonal
shafts, 11mm across flats, spring loaded.
Roller
Curves:- Comprising a
multi grooved anti static steel roller fitted with
a plastic tapered, precision moulding. The curved
sections are available in 30º, 45º, 60º
and 90º angles
Main
Advantages:- a) Versatile and economic powered
conveying; b) Offers high energy efficiency;
c) Accumulation with minimal line pressure;
d) Modular construction offers system flexibility.
These combined advantages enable cost effective purpose
designed systems to be achieved, utilising standard
modules.
