Including a PLC to in the design of an adhesive dispenser adds a great deal of flexibility and reduces the overall cost of the system. As with most PLCs, added functionality is built in. With the standard system an operator generally controls the operation of the unit.
The Ashby Cross adhesive systems with Intelligent Dispensing combines volumetric shot size control, gel timer, multiple shot sequences, menu selectable programs, and maintenance features. As an example, if a product requires several shots of different sizes the sequence of shots may be entered into the unit through the HMI. Each time the machine is activated the precise shot size is dispensed each time.
PLC Based Adhesive Dispenser
Timely maintenance of any two-part adhesive dispensing system is essential to the proper operation of the system. The Ashby Cross units provide feedback to the operator such as the number of times the dispense valve has been actuated and the number of overall cycles the metering section has completed. In addition, maintenance set points can be entered which alert the operator when they are reached.
A linear encoder accurately measures the distance the pistons in the metering cylinders travel and relate that information to shot size. Each shot is highly repeatable. The operator only needs to depress the foot pedal.
In terms of cost, the built in features provided with the PLC save thousands of dollars over a similar equipped machine with the same features added as options.
The Ashby Cross adhesive dispensing systems are accurate, require minimum setup, have no phasing of the adhesives seen in many dispensers, and are simple to operate.
Combine Intelligent Dispensing with years of application experience and thousands of field proven systems and you have the seamless reliable dispensing package.
