A car park for doors – flexible production line for\u00a0refrigerator and freezer doors from BSH\u00a0Hausger\u00e4te GmbH in Giengen begins operation<\/strong><\/p>\n

The new production line for refrigerators and freezers from the BSH Hausger\u00e4te GmbH in Giengen<\/p><\/div>\n

Ergonomic workstations as well as networked and energyefficient\u00a0systems – the new production line for refrigerators and\u00a0freezers at the BSH site in Giengen meets all the requirements\u00a0of a modern and eco-friendly production. Part of the production\u00a0line consists of the new highly automated KTT foaming plant\u00a0from Hennecke for the production of refrigerator and freezer\u00a0doors with an insulating polyurethane core. The novelty here is\u00a0an innovative car park concept for the mould carriers, which\u00a0enables a mixed production with various curing times but a\u00a0largely consistent cycle.<\/p>\n

BSH Hausger\u00e4te GmbH has invested several million euros in the renewal of the production line, which came on stream in January 2015. An integral part of the production line is the new KTT foaming plant from Hennecke, jointly developed with BSH. The requirements of BSH for this project were clearly defined: a significantly higher degree of automation in the mixed\u00a0production of various types of doors and a better ergonomic construction\u00a0than in conventional manufacturing systems.<\/p>\n

A refrigerator or freezer door is always built on the same principle. There is\u00a0an inner side made of plastic and an outer side made of sheet metal.\u00a0Polyurethane is poured in between these two elements, which cures as a\u00a0foam and forms a firm connection with the door elements. In addition to the\u00a0insulating effect of the foam, the door simultaneously obtains its stability.\u00a0In conventional door manufacturing, for example with the tried and tested\u00a0ROTAMAT systems from Hennecke, the foam in the door cures in a drum\u00a0system. Here, the mould carrier rotates in a clocked rotating movement\u00a0around a horizontal axis. With this type of manufacture, the operator always\u00a0has the same workflow at a single station. Removing the finished door from\u00a0the open mould, inserting the plastic inner side as well as the sheet metal\u00a0outer side into the mould, and as the final step, automatic filling with\u00a0polyurethane takes place. This operator workflow determines the cycle time\u00a0of the entire plant.<\/p>\n

With the new Hennecke KTT foaming plant, the removal, loading and\u00a0foaming steps are now divided into three downstream stations. This\u00a0division considerably reduces the cycle time. In order to increase the\u00a0flexibility of the system, the doors no longer cure in a drum system, but in a\u00a0type of “multi-storey car park”.<\/p>\n

In the first station, a six-axis robot removes the finished door from the open\u00a0mould with a vacuum gripper. The flat vacuum gripper is designed so that it\u00a0can transport all model variants of the refrigerator doors – one or two-door\u00a0in various sizes. At the second station, the operator inserts the inner and\u00a0outer sides. BSH and Hennecke have paid particular attention to the\u00a0ergonomic design of this workstation. When placing the door elements into\u00a0the open mould of a conventional plant, the operator inserts one part into\u00a0the lower mould half and the other part at the top into the open mould lid.\u00a0For the insertion into the lid, the operator must really stretch. To avoid this,\u00a0Hennecke has simplified the insertion. The operator places the inner and\u00a0outer parts only into the lower mould half. When transferring the mould\u00a0carrier to the third station for filling, the mould closes and opens again\u00a0immediately. In doing so, the sheet metal outer part is taken into the upper\u00a0mould half.<\/p>\n

Two mixheads on a linear system pour the polyurethane into the mould.\u00a0With a small door only one mixhead is at work, with large or two-piece\u00a0doors both mixheads are used so that the mould can close again quickly.\u00a0For each door type, a special foaming programme and the necessary\u00a0curing time is stored in the control system.<\/p>\n

Then the plant moves the mould carrier via a central lift into a free park\u00a0position within the four-storey structure. The lift then fetches a mould carrier\u00a0with a finished, cured door and moves it from the removal station back into\u00a0the production process. Up to ten mould carriers can run in the system\u00a0simultaneously.<\/p>\n

This “car park system” gives BSH the opportunity to run a mixed production\u00a0of different types of doors. No matter how long a door needs to cure, the\u00a0cycle of the plant remains largely the same. An infeed and outfeed station\u00a0for the mould carriers enables the moulds to be changed during production\u00a0without causing an interruption. Therefore each mould carrier is designed\u00a0self sufficiently. It is equipped with a motor to open the mould, a\u00a0compressed air reservoir for the air cushion to execute a parallel stroke\u00a0during opening and closing, and an electric temperature control to provide\u00a0the desired temperature during curing.<\/p>\n

The BSH site in Giengen focuses consistently on the topic of industry 4.0.\u00a0The entire production line is interconnected. This enables, not lastly,\u00a0perfect coordination with the cooling device assembly line, where the\u00a0refrigerator and freezer doors must be made available in a timed manner.\u00a0The devices manufactured by the company are not just for the German and\u00a0European markets; they are also sent from Giengen to the entire world.<\/p>\n
