ELECTRONIC PLURAL COMPONENT PROPORTIONER |
摘要 |
An electronic apparatus is provided for dispensing plural component materials having first and second (and optionally third) components and a desired ratio between the components. The apparatus has first and second reciprocating pumps ( 4 ), each of the pumps ( 4 ) being connected to a source of one of said components, first and second reciprocating drivers ( 5 ), each driver ( 5 ) being connected to drive one of the pumps and forming a driver-pump set, a position sensor ( 6 ) attached to each driver-pump set, each position sensor ( 6 ) outputting increments of resolution corresponding to a fixed volume being pumped by the driver-pump set to which it is connected, and a controller attached to the drivers and the position sensors to alternately move one of the driver-pump sets one said increment and the other of the driver-pump sets the product of one increment and the ratio. |
