Manufacturing innovationHas mounted sensors on machines in production to measure OEE performance live. The operators can monitor the performance on tablets and get indications if machine settings need to be adjusted. Data from all machines is aggregated in a dashboard, which the production manager can use to track OEE performanceHas made a configurator for managing product variety. Currently, customers can use the configurator to design a productHas invested in a new intelligent production line where the whole process except feeding and packaging is hands-off. The production line’s design reduces changeover times from approximately two hours to 20 minHas installed an intelligent tool cabinet, which assists employees in picking the correct tool. The cabinet also keeps track of tool inventory levels and informs management if a reorder point is reachedIntroduction of an AGV in the production to move products to and from inventoryDashboard in the control room, which shows quality control results from production. The controller in the control room uses this information to assess whether adjustments are needed in the productionSensors on the production line shall collect OEE data to continuously monitor the line, identify problems, and improve efficiency
Prior solutionOEE monitoring was calculated when the production order was finished. Operator experience informed adjustments to machine settingsThree employees would design the product manuallyUse other production lines with longer changeover times and more manual handling in the production processEmployees would grab the tools they needed, and the need for reordering had to be controlled manually. Also, tools were often not returned after the end of use, and colleagues had to search the production to locate a toolAll movements of products in the production were performed with manually operated forkliftsAll results from one day’s quality control were collected into one file, manually transported, and handed over to the control roomIdentification and evaluation of problems on the production line was based on operators’ experience
Future extensions of the solutionIntegration to ERP system and more features in the dashboardThe following steps are to connect the configurator to a webshop and design it to generate data to produce the productSensors are built into the production line, so the company looks into which data is collected and how it can exploit it to improve the production line further. The company is also planning to introduce AGVs to the production lineThe tool cabinet will be linked to customer orders to ensure the correct match between product specifications and tool attributesThe current project focuses on introducing one AGV, but once the company has successfully installed this, it expects to invest in more AGVs to replace manual transportation in productionThe dashboard is continuously updated with new features based on inputs from operations and managementEventually, all information on whiteboards and paper in the production should be digitalized
