| 摘要 |
<p>This invention concerns improvements relating to staged production in volume manufacture of products such as ceramics tiles (or other multi-stage process industries including, for example, food, leather, timber, plastics and textiles). Parameters are measured at multiple points along the process and correlations are identified between input and output parameters. Interdependencies between parameters are stored and the process is controlled at multiple stages according to a stored interdependency in response to a given parameter change. Output parameters may include: density of or defects in products emerging from a press (26); parameters of glaze applied in a glazing station (30); or moisture content or grain size distribution of particulate material from storage (24). Input parameters may include one or more of: press pressure, press speed, pump pressure, air temperature and air flow rate threshold.</p> |
