FEATURES

Multiple guns can be mounted on horizontal arms which extend from the vertical moving bars connected to the carriage. These are capable of performing same or various motions. There is also a facility to attach fixed guns which can be angled to access difficult coating areas. The carriage is programmed to move the vertical bars at variable stroke and speeds. The carriage moves the bar up and down and hence the guns up and down through AC geared motor. The carriage is supported by a very sturdy frame structure. The entire waggler 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 inbuilt analogue based controller to achieve the desired speed. The stroke can be varied mechanically.

WAGGLER SPEED CONTROL FEATURE

Speed of the moving guns can be varied very easily by varying the speed adjuster at the rear of the waggler. This step less control in turn gives a signal to a most update A.C. frequency drive and an inbuilt analogue based controller to achieve the desired speed. The speed of the moving arm of the waggler can be varied from 0 - 28 cycles per minute.

WAGGLER STROKE CONTROL FEATURE

The movement stroke of the waggler carriage is achieved by physical variation of the stoke control mechanism on the waggler.

Stroke of each of the mounted guns can be varied in the following manner.

Vary the gun mounting rod distance from fulcrum. By increasing the distance of the gun from the fulcrum, the resultant arc (movement height) of each gun can be increased. Thus in the below drawing you can observe that to achieve a total stroke of 2000mm, the moving rod distance from the fulcrum is 1250mm and the resultant stroke of each gun is 1000mm. Two guns shall be required to achieve the desired stroke.

Even in this mode you can observe that the fulcrum can be moved front to rear to further achieve a variation of 300mm in the set 1000mm stroke for each gun.

This larger gun stroke coupled with lesser number of guns are an ideal combination for conveyor line speeds of about 0.6mtr/min to about 1.5 mtr/min.

Distance of Fulcrum to Gun = 1250mm

Stroke = 1000mm

Similarly if you vary the distance of the Fulcrum to gun to 625mm, the resultant stroke = 500mm

And if the distance of Fulcrum to Gun is = 2500mm the Stroke is = 2000mm

By reducing the moving rod distance from the fulcrum you can achieve a lesser stroke. Thus in the below drawing you can observe that to achieve a total stroke of 2000mm, each gun is kept at a shorter distance of around 625mm from the fulcrum and each gun achieves a stroke of 500mm. Four guns are required at this combination to achieve the desired 2000 stroke. Thus in this option we can reduce stroke of each gun to increase number of guns on the waggler to achieve higher conveyor speeds.

Even in this mode you can observe that the fulcrum cam be moved front to rear to further achieve a variation of 300mm in the set 500mm stroke for each gun.

This lesser gun stroke coupled with higher number of guns are an ideal combination for conveyor line speeds of about 1.5mtr/min to about 3.0mtr/min.
