Two hundred years of brewing history haven’t made Greene King shun new technology when it comes to keeping ahead in a highly competitive industry.
With demand rising, it was decided to speed up the cask handling line. This is now built around PLC control and a high speed vision inspection system. The system incorporates CV1000 PLCs, each with three expansion racks and more than 1,000 inputs and outputs.
The PLCs enable the automated system to rotate the casks using a system of inverters until the shive (air plug) is detected, then to signal to a pneumatic tool to spear the plug. Then the keystone (tap plug) is removed. PLCs then control the entire wash sequence.
The interaction between the vision system computer, the PLCs and the inverters ensures that all the detection and positioning operations can be performed with accuracy at very high speed.
