Bagging Conveyors

10/15/2008 4:14 AM

Hi,

I am a Maintenance engineer at a bagging plant for Urea.

We have a number of bagging conveyors which are used to feed the bags towards the trucks which are manually loaded by workers.

Once these urea bags are moving on the conveyor belts the Idler rollers tend to get jammed very often due to:

1) Threads (used for stitching the 50 kg WPP bags) getting stuck in the rollers

2) Urea going inside the rollers.

These jammed rollers also cause the conveyors to detrack .

If someone has any experience of using side travel rollers or scrappers ( wipres) please do share your experience with me in detail.

Regards

Most bagging conveyors have covers over the ends of the rollers of the bed to reduce contamination of the bearings on the ends during spills, funneling it to the floor. Are these in place as they would also help keep the thread from the stitching from wrapping around the axle shaft.

Also the stitching machine is it leaving too long of a tail? Adjustment to this may reduce the thread problem.

How about some pictures so that we can better see what you are dealing with?

Hi Guest:

Please visit www.artecrobotics.com and view under "Products" a Robotic system for truck loading/unloading.Although demonstrated for handling LPG cylinders, it is adaptable for handling 50 Kg. X 10 bags at-a-time. It can place individual bags in different positions and orientations on the truck.

This system can eliminate dependence on whimsical labour sub-contractors who have the potential to cripple operations being at the final product "sale" point. A unit can also be offered for handling the bags coming off the filling carousel/stitching unit and eliminate the troublesome conveyors. The whole system is synchronisable with the production output and despatch operations, and seamlessly integrate to the MIS.

Having conducted a detailed survey of one of the best Fertiliser plants in India for induction of Automation of Process control and operations, a certain extent of familiarity and experience can be brought to bear on the problems in a cost-effective way.
