The ability to control and optimise the just in time delivery of materials to the production process is one of the fundamental challenges for the future of automated manufacturing. Peter Barber, Head of Solutions Engineering at Panasonic Factory Solutions Europe, looks at the progress being made.
The production line is set-up and ready to run the next work order. The ERP system says the vital components are in stock but when you look them up in the warehouse - they are nowhere to be found. It’s a mystery to rival a classic episode of the television detective series Columbo! Further investigation finds the reel of components has already been part used on another production line and is waiting to be transferred back to the warehouse. However it is now resolved, it will mean downtime and costly delays. This type of material control issue is one of the fundamental challenges facing manufacturers today.
The headlines are only too clear. Supply chain issues, rising prices and labour shortages are putting the squeeze on manufacturing like never before. To combat these additional costs, manufacturers are accelerating their move to the autonomous factory. The vision is understood. A manufacturing facility that is connected to the supply chain in real-time and able to flex orders and production to meet demand. But where are we today and how close are we to this utopia?
If we take Surface Mount Technology (SMT) production, the process used to create the Printed Circuit Boards (PCB) that go into everything from cars to washing machines and our mobile phones, the production line level control is already well established. The objective is to keep overall equipment effectiveness (OEE) as high as possible. Panasonic offers PanaCIM Basic Modules here for material verification, traceability, production monitoring and production analysis. Production monitoring and analysis are useful additions in that they provide visual alerts to the operators about potential issues that could interrupt production, for example, running low on components. In addition, they keep tabs on the mechanical side of the machine, for example, actively monitoring the feeder to ensure defect rates aren’t rising above target or that predicted maintenance is happening at the correct time.
Production line changeover
The next level is management of the entire SMT production line. Being able to automate and control the changeover of production on an entire line of machines, from different providers. This is where Panasonic Intelligent Line Network Box (iLNB) comes in. Imagine an automotive parts manufacturer making different versions of a unit for many of the big car brands. One day they could be manufacturing units for BMW and the next for Ford. iLNB manages the workflow across all machines in the production line. It ensures the correct programmes are downloaded to each machine, checks Work Order verification and gathers all traceability data into one place – increasing efficiencies and simplifying the process.
Factory floor visibility
At the next level up, things really start to get interesting with factory floor visibility becoming a reality. This where Panasonic’s PanaCIM Advanced module of Material Control operates.
Material Control is the Detective Columbo of the automated manufacturing world. It provides a level of visibility across the entire production process. It’s the glue that makes efficient and automated manufacturing work by understanding how many of each component are available, where they are located, for example in the warehouse or already work in progress (WIP) on another production line, and where and when they need to be moved. Through this unique visibility, the module is able to allocate and plan the delivery of components to pending Work Orders and deliver parts Just In Time and Just In Sequence to the production line for Work Orders that have already started - reducing downtime and increasing productivity.
Entire factory level control
Then we begin to connect in the factory-wide systems with Manufacturing Execution System level software. Panasonic PanaCIM Gen 2 has two modules of interest here. Its Asset Management System can manage, control and optimise the entire production processes across the factory. It provides the ability to automate and control ranges from predicting optimum maintenance times, right down to controlling the optimal performance of different equipment, such as feeders and nozzles, with the ability to interlock these parameters as required.
The second module is Process Tracker, which provides a factory-wide solution for process control and material management. Process Tracker provides total control of the entire manufacturing area ensuring process verification and traceability down to levels such as the amount of torque used on a screw. The potential for this depth of insight and control offers a whole new level of opportunity for fine tuning production, eliminating errors and improving quality and productivity.
Wider supply chain integration
Imagine these systems then connecting into the wider real-time supply chain software applications, powered by AI, that are being driven by Panasonic company Blue Yonder. It’s not hard to then see a world where fully automated manufacturing becomes a real possibility.
But these visions are built one layer at a time. Every manufacturer is starting from a different position. The key to success is increasing visibility, control and automation one step at a time from the individual production machines up to factory wide level.
It will not happen overnight, but Panasonic is putting the building blocks in place to make this vision a reality. Now, in the meantime, where did I put that reel of components?

The evolution of the latest generation of robot welding systems draws on a long history in Japan of incredible innovators renowned for their attention to detail, precision and quality.
Panasonic Factory Solutions Europe today introduced its next generation G4 Robot Controller designed to set new standards in Robot Welding for speed, quality, safety and connectivity.
Panasonic was founded in 1918 in Japan by Konosuke Matsushita. Since then, Panasonic has constantly developed new technologies and continued to grow its business. In 1957, the Robot & Welding sector was founded with the first arc welding machine.. However, did you know…?
Many people unfamiliar to the world of electronics manufacturing are often surprised by the number of manual assembly processes that are still involved. The challenge of placing larger or odd-shaped components on a Printed Circuit Board (PCB) still requires human assistance.
