Method and device for supplying lubricant to an I.S. glassware forming machine

摘要

The invention relates to a method for supplying lubricating points of an I.S. glassware forming machine, wherein a used lubrication system comprises a plurality of lubricant metering devices (29) that are provided to output lubricant to a plurality of lubricating points, that are to be lubricated, of the glassware forming machine and are allocated in each case to one of several lubrication circuits (23-28). The lubricant metering devices of a respective lubrication circuit simultaneously output a predetermined amount of lubricant in each case cyclically with a time interval allocated to the lubrication circuit. The lubricant metering devices are allocated to lubrication circuits in dependence upon temperatures that have been measured in direct proximity to lubricating points, and are allocated such that the temperatures of the lubricating points of a lubrication circuit are within a predetermined temperature range. The amounts of lubricant provided at the lubricating points are controlled in that the length of the time interval allocated to a lubrication circuit is determined in dependence upon temperatures, that have been measured in direct proximity to lubricating points of the lubrication circuit, using a set of evaporation characteristics of the lubricant. In accordance with the invention, the consumption of lubricant can be further reduced. The invention further relates to a device for implementing the method.

1. A method for supplying lubricant to a plurality of lubricating points of an I.S. glassware forming machine, comprising:
providing a lubrication system having multiple lubrication circuits, and further having a plurality of lubricant metering devices which output the lubricant to the lubricating points, each of said lubricant metering devices being allocated to one of said multiple lubrication circuits, and wherein the lubricant metering devices of a respective lubrication circuit simultaneously output a predetermined amount of lubricant cyclically whereby successive outputs of said predetermined amounts of lubricant are provided with a time interval between the successive outputs being specific to each respective lubrication circuit; allocating said lubricant metering devices to said lubrication circuits in dependence upon temperatures measured in direct proximity to at least a series of lubricating points, said allocation being carried out such that the temperatures of the lubricating points of a respective lubrication circuit are within a predetermined temperature range; and controlling the amount of lubricant provided at the lubricating points, said controlling step including determining the length of the time interval allocated to a respective lubrication circuit, whilst taking into account a set of evaporation characteristics of the lubricant, in dependence upon temperatures that have been measured in direct proximity to lubricating points of the respective lubrication circuit, by using a set of the evaporation characteristics of the lubricant.
