Model TA Belt Alignment Control

The Model TA Belt Alignment Control provides an indication when a conveyor belt has drifted off to a dangerous misalignment condition. The output contacts of the Model TA can control up to two separate circuits, one for machinery shutdown and one for an alarm. Model TA is relatively inexpensive protection that provides benefit by saving the time, money, and labor associated with replacing a damaged conveyor belt.

Description

The Model TA Belt Alignment Control protects conveyor belts from damage due to belt misalignment or runoff. These controls are used in pairs with the control placed on each side of the conveyor belt. Each unit can be equipped with two micro switches to produce signals indicating belt misalignment at two deviation points. The first signal point could indicate small belt deviation by sounding an alarm. The second signal point could guard against extreme belt runoff by shutting down the conveyor.

Model TA Belt Alignment Control units are always used in pairs with one placed on each side of the conveyor belt, usually near the head end of the conveyor. They may also be placed at the tail pulley and at selected points along the conveyor. The unit should be mounted on supports so that the roller is positioned in a vertical direction to intercept the conveyor belt at it’s midpoint. The roller is 9-3/4” high. The point of interception would be at the 4-7/8” point. Units should not be mounted too close to the belt because false signals would result. In most applications, the units could be mounted about 1” from the belt, eliminating false signals but protecting the belt against wide deviations.
