An electronic system to control the cooling of molds in glassware forming machines, wherein the articles and/or the molds in which said articles are being produced, are subjected to a suitable cooling to control the thermal relation therebetween so that the articles can be suitable handled and shaped. In this system, the velocity of the machine, the heat profile of the glass gobs and the gob weight are continuously detected and fed as signals to a microprocessor which determines the heat exitation of the molds when receiving the glass gobs, in order to control the necessary cooling air flow rate and compensate for variations in the thermal conditions of the molds. Said microprocessor is also fed, at predetermined intervals of time, with signals representative of the pressure, temperature and humidity of the cooling air, in order to determine the physical properties of the cooling air and relate them with the operation conditions of the machine for compensating for changes in the physical conditions of the ambient, and for forecasting the changes in the ambient conditions for correcting, if necessary, the parameters initially gave to said microprocessor up-dating and self-correcting those initial values and for maintaining the operation of the cooling system even when said pressure, temperature and humidity signals are lost.

Electronic system to control cooling of molds in glassware forming

Article handling apparatus for use in conjunction with a glassware forming machine is effective to remove finished ware from a dead plate where it has been placed to cool and transfer it to a moving conveyor. An electronic control synchronizes the movements of the apparatus with the cycle of the forming machine and deposits the ware on the moving conveyor with a component of velocity in the direction of the conveyor movement which effects smooth transfer to the conveyor irrespective of variations in conveyor speed.
