When carrying out retrofits, Winkler und Dünnebier Süßwarenmaschinen GmbH replaces outdated components with new, modern technologies, thereby updating older plants to the technical status of a new plant. Converting from hydraulics to servo technology or adopting customised solutions for the replacement of discontinued servo components give older machines a boost in efficiency, reliability, spare parts availability and service life.
WDS is known for its durable confectionery machines for the production of all pourable and tearable masses. Plants from the 1950s are still in operation today and receive support from the WDS service department. Modernising older plants with customer-specific retrofits can increase the productivity and efficiency of an existing plant and is therefore a potentially more economical solution than investing in a new one. As the familiar machine concept remains the same, the same functional basic plant, user-friendliness and process expertise can also be retained. The retrofit measures can often be carried out with minimal downtime.
Through various retrofit measures, confectionery machines with durable mechanics can still be comprehensively modernised decades after purchase. At the most advanced level, plants can be upgraded to the technical standard of a new plant. Such modernised plants offer tangible advantages in terms of efficiency, production volume, production quality and sustainability. The choice of whether to modernise an existing plant or purchase a new one can only be made on a case-by-case basis in consultation between the customer and WDS.
There are many reasons for modernising plants. WDS began converting the first old hydraulic depositor machines to servo technology in 2011. This became necessary because many parts were no longer available, making it impossible to guarantee the supply of spare parts. Moreover, due to the hydraulic oil used in older systems, there are now hygienic reasons to switch to more modern solutions. Advantages in terms of process engineering include more precise movement sequences and simpler operation.
In 2019, WDS carried out an extensive series of retrofit measures for its customer Continental Candy Industries B.V. (Netherlands). After WDS informed the customer that the hydraulic components used to drive the depositor machine had been discontinued and thus the availability of spare parts could no longer be guaranteed, CCI decided to modernise the existing mogul plant type 361B to make it more fail-safe and efficient. Dating back to 1983, the plant’s hydraulic depositor machines were retrofitted with servo drives. In addition, an entirely new switch cabinet and an up-to-date HMI were installed.
The customer also decided to have WDS install new depositor hoppers and pump systems with the latest technical design. In the scope of the conversion project, the existing feed unit and stacker were converted by replacing them with the latest design. The electrical conversion process required all safety switches to be converted from 230 V to 24 V or replaced and subsequently integrated into the new control system. The entire process from placing the order to installation at the customer’s site took approximately six months. During this time, the conversion parts could already be tested at WDS. This meant that the installation and start-up could be completed according to a defined schedule within a downtime of four weeks. Before starting the on-site installation, CCI had already carried out some preparatory work, such as checking the cable labelling, opening the cable ducts and dismantling the existing plant (e.g. removing the depositor hopper and pump system). The team of 7 WDS and 6 CCI specialists then began the installation of the new components, connecting the new switchgear unit and modifying the existing installations. “The retrofit conversion to servo technology enables us to continue to operate our plant while meeting standards of safety, hygiene and profitability. The new plant control in line with the current standard enables us to produce with an improved OEE. Safety for our staff has improved and the new HMI control system has given us more insight into the performance of our machine.”, says John van Dongen, Project Coordinator at CCI.
When servo components were discontinued by Bosch in 2018, WDS worked with many affected customers to develop solutions to preserve and modernise the machines. Customers using the PPC R02 servo control, DKC servo controllers and MHD servo motors were offered combinations of Bosch service contracts to extend the availability of spare parts and to replace the discontinued components. This required working with the customers to determine which model was suitable for their needs and those of their plants. The main questions to be addressed here are how long the plant is expected to remain in operation and how much downtime could be allowed for the retrofit measures. With many retrofits, a comprehensive spare parts inventory can be carried out simultaneously so that the plant cycle rate can also be optimised in a single step or so digitalisation measures can be applied for remote maintenance access or data analysis to monitor the plant status.
During a retrofit conversion for one customer, 49 old MHD servo drives were replaced with new MS2N drives with new gears. In addition, the entire main switch cabinet was replaced with a new switch cabinet that meets current WDS standards. All supply and feedback cables of the old servo drives were replaced with suitable hybrid cables and, instead of Profibus cables, complete Ethernet cabling was laid for all replacement components. In this case, it was possible to use existing cable routes for most of the new cabling. Here too, a new HMI and state-of-the-art control units were employed to ensure simple operation after the conversion.
Approximately four months elapsed between the placement of the order and the FAT at WDS. WDS completely set up the new switch cabinet and the terminal box components and also installed and wired all servo axes, including the gears. Thanks to the provision of a test CPU and a test MLC, all tests could be carried out on three new HMI control units.
WDS has already successfully completed projects involving the replacement of 2 to 104 servo axes. By archiving all plant documentation from the year of construction of 1970 onwards, WDS can respond quickly and contact customers when components are discontinued.
Initially, a budget proposal is made on the basis of the existing data, after which WDS works closely with the customer to adapt it to their specific needs. Key factors are then identified by way of an on-site assessment. It is important, for example, to determine the position of the switch cabinet and make a record of any customer modifications. The installation process and installation support are planned in detail. The final quotation is then prepared, after which the retrofit measures are implemented.
