Everything is connected

A tangible future
For example, in Bühlertal

Manufacturing locally while remaining competitive. Implementing client requests in high quality at high speed. Assuring the longterm existence and sustainability of our site. Kärcher is heading in this direction and going fully digital at the Bühlertal site. Even before the Bühlertal 5.0 project started, the plant was already over 50 % automated. Within just two years, production control, manufacturing and intralogistics had all been introduced or further automated. But why do driverless vehicles need swarm intelligence and why do employees now have to carry much less weight? Let’s take a look.

Taking seasonal work digital: business goes on

Large projects have a habit of petering out before they come to anything. This is a particular problem when the scope is too big and employees are not on board. Katja Räntzsch, project manager for Bühlertal 5.0, explains: “Right from the start, it was important that all staff were involved because they are the ones who will have to take on many of the tasks in the implementation process. That can only happen if they are motivated and open to new ideas – not to mention that business goes on and we have to reliably run the operational side of things, too.”

In Bühlertal, operations comprise, for example, in-house plastic manufacturing of 50,000 components every day and the production of 25,000 products for domestic and professional use. Then there is the particular challenge posed by cleaning technology being a seasonal business. In the retail segment, demand for high-pressure cleaners is especially high in spring and summer. “As soon as the sun comes out, orders spike and they need fulfilling quickly – so we work with a team of 570 permanent staff plus an additional 300 seasonal staff across three shifts,” explains Räntzsch.

Once a project to tackle has been identified, a suitable digitalisation strategy must be selected. “We are not interested in commissioning large, tailored programming projects which then simply do not work,” says Räntzsch. “We use fairly standard solutions which already work and simplify processes using software where we can.” The foundation for all of this is high-performance, failure-resistant Wi-Fi and the right in-house network – so expanding our digital infrastructure was the first pillar of the project. Then we turned to the core issues of production control, automation and intralogistics. An MES system is at the heart of our production software, and it will be expanded incrementally with SAP interfaces by 2021. “We used to use Excel a lot, as manysites do,” acknowledges Räntzsch. “That works, but it is labour-intensive and relies on just a few experts.” The new system is even able to handle all of the detailed production planning, from preproduction to final assembly and all the way to quality control. “At the moment, we are finding potential for optimisation on an almost daily basis,” says Räntzsch. “For example, our injection moulding machines have always had high capacity utilisation, but the MES has managed to improve this.”

Humans and machines: working hand in hand

数字革命已经达到世界的工作,and some companies are automating with the goal of reducing staffing levels. Katja Räntzsch explains why that is not the goal in Bühlertal: “At the core of all of this is the goal of increasing the plant’s output – by improving working conditions and smoothing processes." So the production lines were analysed, showing where work could be made easier. The final assembly of the K2 pressure washer involves manually installing the 2 kg pump – a very strenuous and not particularly ergonomic task when repeated over and over. From 2020, this task will be completed by a machine. Steps will also be taken to ease the strain of working on our professional products. This will be particularly advantageous when dealing with the heavy machines. “Just like in the automotive industry, underride driverless transport systems will take the HDS high-pressure cleaner to each workstation in future – greatly improving ergonomic standards.” Once a product is ready to be picked up, the packaging robot places it on a pallet. The machines are then picked up by a driverless transport system (DTS). “This is truly fascinating technology,” reports Räntzsch. “And the DTSs work using swarm intelligence. They don’t simply complete a route; the DTS closest to the current task will pick the product up.” Then it goes to the warehouse or to direct dispatch – where the plant has improved its quota from 30 % to 50 % using the measures already implemented, with a goal of 70 % going forward. “Direct dispatch means orders are addressed and sent out quickly, with minimal storage costs.”

Well on the way – but not there yet: progress is motivation

许多举措已经或处于在Bühlertal实施的过程中 - 这就是两年内。“我们也在成为一家造林的途径，”Räntzsch报道“。在与整个公司的换算策略中保持一致，我们正在在工厂设置人力资源管理，以便没有自己的计算机的员工可以使用数字终端设备要求假期并报告病假。由于所有这一切的证据，增加了生产力和成本的降低是所有这一切的工作。“但是这个项目不是我们的结束;这只是一个开始，“Räntzsch笑着说。“因为我们每天都想进一步走一步，就像我们到目前为止一直在这样做 - 总是可以完成更多。”
