I'm spec'ing out a conveyor belt and want a control mechanism to make sure that it runs straight. I know there exists a product for this since I've seen the function in an older tender, but don't have a clear idea how the device looks like and what it does - googling *"Geradelaufkontrolle Förderband"' didn't yield anything helpful.

Is there a device that gives me an alarm when the belt runs off course, what is it called, and how does it work?

  • $\begingroup$ Gust in case it helps with searching, the adjustment that keep the conveyor running straight is generally called 'tracking.' A closed loop/belt can be said to be 'tracking straight,' 'tracking left' or 'tracking right, etc. $\endgroup$ – Ethan48 Jul 21 '16 at 15:31

Alignment Monitoring

There are many switch systems that can be mounted to the frame that will detect when a conveyor is beyond the acceptable limits of alignment. A google of "Conveyor Belt Alignment Sensor" brings this within the first page.

http://www.go4b.com/usa/technical-support/product-manuals/belt-misalignment/touchswitch-belt-alignment-sensor-manual.pdf

Sensors will assist with major changes in alignment and sudden failures but they do not compare with the ability of a trained belt manager who walks the belts at least every shift.

Equipment Install

While the travel rollers on a conveyor system can be set to correct for a minorly inconsistent alignment of the conveyor structure it adds additional wear to the bearings, rollers and belting. The additional wear will also reduce the efficiency of your conveyor if that is a concern to your operation. In all situations I recommend laser levels for the install of conveyor structure (even in semi-mobile installs) If this is a cross country type conveyor system that will deal with variable terrain crossing, vertical and horizontal curves or surface to elevated structure transitions using a knowledgeable surveyor is critical to alignment and the foundations should not be underestimated.

Operating Alignment

When major components on the conveyor are replaced or at the completion of the install the start up and training of the conveyor is important to insure that there isn't a failure due to premature wear. This site has a good set of basic knowledge about training and individual adjustment for travel rollers. http://www.shippbelting.com/BeltTraining.aspx
