MIXING, WEIGHING & CONVEYING
SYSTEM IS MINDFUL OF ACCURACY
A conveyor system from BS Handling, with six pick-to-light stations, has increased accuracy and throughput at Mindful Chef
into their distribution hub in Redditch. Founded by three friends, Myles Hopper, Rob Grieg-Gran and Giles Humphries, Mindful Chef supplies subscribers with recipe kit boxes which include ready-measured, fresh ingredients and easily followed healthy recipes. Since it was established in 2015, the business
B
has enjoyed rapid growth and this was a key driver in the desire to improve the throughput and accuracy of the distribution operation. BS Handling Systems was recommended to Mindful Chef by software controls specialist, IDC, which has been a long-term supplier to Mindful Chef and has worked closely on projects with BS Handling for many years. Matthew Maxwell, the production lead at
Mindful Chef, said: “Our goal with the new line was not only to increase the throughput performance, but also to significantly improve the accuracy of the picking process. “From day one of working with BS Handling it
was clear that they were no ordinary supplier. There was always a willingness to go the extra mile and it was obvious that they had our best interest at heart. Phil Taylor, who was BS Handling Systems’ key account manager on the project, was flexible, easy to work with and a great communicator.... “The result was a 40m ‘bus stop’ style
conveyor system with six pick-to-light stations and a quality control (QC) station at the end of the line to further improve accuracy. In essence, it is a very simple solution, but it is driven by a sophisticated controls software system.”
Pick-to-light stations At the infeed end of the system an automated box erector machine prepares the outer delivery box and sends it off down the line. Each box has a barcode on it that, when read by a scanner, tells the system which pick-to-light station or stations it needs to go to. Once the box has been diverted to the correct station, another barcode reader scans the box which automatically lights up the

ritish healthy meal kit retailer, Mindful Chef, turned to BS Handling Systems when they wanted to add automation
items that need to be picked for that order from the flow racks above. The operator then picks each required
ingredient from the lit up flow racks, pushing a button for every item picked to tell the system that it has been taken. Once the operator has picked all the items for that box they push the white ‘order complete’ button which automatically sends the box back onto the main conveyor. The box then travels either to another pick
station or the QC station prior to reaching the end of the line. An automated leaflet inserter drops in any paperwork or promotional material required for each order. The QC station is governed by three criteria,
with boxes diverted for checking if the system: a) thinks they have incorrect or incomplete orders; b) the order is for a customer who has complained of an error in the last four weeks or c) boxes are randomly sent for QC. The boxes sent into the QC station are checked by an operative to make sure all is correct before sending the box back on the main conveyor. When everything is correct, the boxes pass
through the automatic box closer where they are sealed before travelling to the end of the conveyor. Here, they are taken off and stacked on a pallet before being wrapped and driven by forklift truck straight into the back of a carrier’s trailer. Maxwell again: “Although it is early days, we have already seen a significant improvement
in throughput of at least 20 percent. In addition, we are working on box sequencing which will add a further 30 percent increase in throughput. The new system is capable of handling 1000 boxes an hour, although we are currently operating at a maximum of around 650 to 700 boxes an hour. “In terms of accuracy, we have achieved
considerable gains. When the operation was manual, an error rate of around 1.5 percent was normal. With the new system our target is 0.5 percent, and although we are not quite there yet, we expect to reach that target soon as the team learn more about the system and refine the process. “The new line has eliminated much of the
‘human error’ element from our picking operation. This, from our customers’ viewpoint, means they rarely experience any inconsistencies with what they ordered. And, of course, having totally happy customers who stay loyal to the brand is our ultimate goal.”
Planning for the future “The gains we have made with this new automated pick-to-light line have given us the confidence to place further orders with BS Handling. These include two more pick-to-light conveyor lines with robots at the dispatch ends to automate the removal of the boxes from the conveyors and stack them on pallets. “The aim is to have the new lines operational
by the end of Q3 whilst the robots will be added early in Q4. The total investment in this automation process will be in excess of £1.6 million; the savings in terms of time and money, however, will deliver a payback within 12 to 18 months and, more importantly, boost customer retention levels. “Partnering with BS Handling Systems has
helped us drive the business forward, improving our customer service by minimising errors and speeding up the throughput of our distribution operation...” concluded Maxwell.
