*General Fabrication/Accessories for Conveyor Projects
Rusmail Powered Belt Conveyors & Stainless Steel Chutes
We were contacted recently by a major company who needed to unload cash
boxes from a security vehicle into a secure area within a building. Initially,
they felt they required a gravity
roller conveyor, but were concerned at the speed of the boxes down the
decline from the access point to the working height of the cash desk. We
suggested a chute would be more adequate and minimise the speed of decent.
This approach was adopted and we supplied a bespoke stainless steel chute,
approx. 2 metres long x 600 mm wide.
We recently completed an order for customised gravity
roller conveyor and worktables. The tables were required to have a special
top and also a storage shelf below. The top needed to be in a material other
than painted steel or stainless steel and galvanised steel was selected
as the cost-effective solution.
If you require general fabrication work - tailored to your specific requirements,
in mild steel, stainless steel, galvanized steel or aluminium, please contact
us. We make chutes, tables,
platforms, steps, bridges, safety rails etc. etc.
*Incline Belt Conveyors - Product Slippage
Rusmail Belt Conveyors Products Slipping?
We touched on this problem in our previous News Update and said we would
discuss this and suggest some solutions.
Incline belt
conveyors provide a cost-effective solution for moving products between
different floor levels. It is a well-established application and we have
designed and installed hundreds of such belt
conveyors for a variety of customers and applications. The conveyor
design needs to allow for the size and weight of the product, the height
differential to be achieved and the surface characteristics of the material
in contact with the belt to determine at what angle the product will slip
down the belt.
For most unit load applications, incline angles between 20 to 30° would
be acceptable and belts would have a special grip-top surface, which would
be quite acceptable. However, occasionally an installation that may have
been conveying satisfactorily may start to see products slipping down the
belt. This may be the result of a change in the product packaging i.e. a
matt finish to a gloss finish. This change may be made without the operator's
knowledge.
If using plastic tote boxes to carry products, these may become warped so that contact between the bottom of the box and belt is reduced. This would be particularly critical when transferring between conveyors or at a change in level and/or direction. If the belt surface has become worn, dirty or dusty, this will further complicate the problem.
To overcome such slippage problems could be time consuming and costly if changes to the product itself, or the packaging, or boxes are necessary, or at worst if the conveyor installation itself has to be modified.
A low-cost “quick-fix” solution, which may solve the problem, is to use a belt dressing. This material is supplied in an aerosol can and is simply sprayed onto the belt surface. The spray provides a “sticky” belt surface and can significantly reduce slippage if this has become a problem.
