Document Type and Number:
Japanese Patent JP2003517666
Kind Code:
A
Abstract:
A dispensing apparatus (10) is capable of robotically dispensing plural component materials such as sealants and adhesives with the same precision as single component products and yet will maintain ratio assurance and integrity for mixing the two materials. First look at the flow rate and if the flow rate is too high, decrease is needed on one of the components. The ratio error is then looked at and the flow rate/pressure differential for the material which is there in excess is decremented. Another level of control is provided in that the ratio error is continually examined and the direction of the ratio error is used for additional control. This provides very precise control of ratio and flow and helps prevent oscillation, hunting and other undesirable characteristics in such a system.
