CONSTRUCTION

The guns are mounted on an arm and extended from a carriage. The carriage is programmed to move in the user decided length and speed depending on the object height and the conveyor speed. The carriage moves up and down through a chain driven by an AC geared motor. The carriage is supported by a very sturdy frame structure. A counter weight is used to balance the number of guns mounted on the spray arm. The entire reciprocator is on castor wheels to facilitate easy movement during colour change.

CONTROL

The movement of the carriage is controlled by a most update A.C. frequency drive and an advanced digital controller to achieve the desired stroke and speed. This advanced digital based controller can also vary the speed in a multi-speed pattern within the same stroke. This feature allows the operator to select three speeds within the entire stroke length, thus customizing coating for the various geometries of a complicated object. This is useful in coating various complicated objects.

The control panel incorporates a user friendly key pad so that the operator can simply punch in the required stroke length and single speed or multi-speed options. Optical encoder and proximity switches are employed for precise feedback of the stroke length. The stroke can be viewed on a two line backlit LCD display.

The following displays can be viewed during operation :

Stroke Length in mm.
Offset Length in mm.
Speed in Mtr./Min.
Multi speeds and their corresponding strokes
