"Historically we had poor control over product giveaway. With the new system, we are now able to drive to eweights." John Baarda
Tomatoes are picked and sent for weighing, wrapping and labelling. The system sees the punnets placed on a conveyor and sent through the dynamic checkweigher (checkpoint M).
Punnets that are within the set weight tolerance are sent to the wrapper automatically and then to a second checkweigher which records the average weight. Punnets that are outside the tolerance are diverted by the Double-D conveyor system installed by D&D Engineering and controlled by the MCI Myrias software. The packs are diverted across to a second packing line where an operator places the punnet onto a manual checkweigher with an E1210 indicator and then adjusts the contents to within the acceptable level. Again the MCI Myrias software controls the E1210 scales, adjusting the traffic lights to optimize giveaway to a minimum. These punnets are then placed back on the conveyor and sent to the wrapper and then the
final dynamic checkweigher.
The second checkweigher continuously communicates to the manual checkweighers what the weighing trends are and automatically adjusts the tolerance band on the manual machines to ensure minimum giveaway. The system also allows line performance and output to be evaluated so that performance can be improved and double handling minimised. Tim Howarth, business development manager for John Baarda commented: "Historically we had poor control over product giveaway – between 8% and 16%. With the new system, we are now able to drive to e-weights."
The checkpoint M is a high precision dynamic checkweigher that can be used for product weights of up to 7.5kg (there are foursystems 750g × 0.1g, 1,500g × 0.2g, 3,750g × 0.5g or 7,500g × 1g). The system with a conveyor speed of up to 230 weighings a minute may be used asstandalone device for monitoring target weightssuch as in the John Baarda case or also integrated into a network if required.
Checkpoint M is controlled by menu-guided touch screen operation with memory space for 50 product records. There are also special graphicsscreensfor displaying statistics, histograms, trend and average value curves to give performance indicators. The MCI Systems Myrias software is a complete production system able to control a complete production facility.
