the optimum ergonomic position of objects for manual assembly. Horizontal and vertical rotation, tilting, lifting, placement, and movement are the basic manipula- tions,” said Vilcek. “The units can be combined into modular systems for loads from 22 to 1325 lb [10–601 kg] with manual or electrical operation. A rotary mod- ule with media feed-ducts allows for the hydraulic, electrical, or pneumatic opera- tion of devices held by zero-point clamping systems without complex boring.”

With the support of Manfred Parr (middle), Roemheld assembly technology product manager, Thermo Fisher Scientifi c’s Stefan Kämmerer (left) and Felix Pergande (right) designed a line of four similar assembly workstations with two of them suitable for the assembly of the larger incubator models.


“Roemheld’s consultation quality is extremely high,” said Pergande. “They in- tensely and dedicatedly responded to our individual requirements. In addition, their products are very reliable and can be confi gured according to our requirements. We do not have to buy anything ready-made.”


For the new manual assembly workstation, ergonomics were of particular


signifi cance to Kämmerer. The earlier incubator series had been assembled on height-adjustable tables, but the 40-lb (18-kg) units had to be moved manually without any auxiliary equipment. “For this reason, preassembly of the inner containers required a lot of handling and was physically more demanding,” said Kämmerer. “This had to be improved for the production of the new series.”


The inside 28 × 18" (711 × 457-mm) casing which is open to the front for the 42-gal (159-L) incubator is manufactured in Thermo Fisher’s own sheetmetal work- shop. In preassembly, an employee covers all fi ve sides with heater foils, which requires that the container be rotated several times. Apart from this, a sensor and a fi xture have to be mounted. The entire process takes about 45 minutes, and the outside casing and insulation are assembled over it. The site in Langenselbold has about 150 assembly employees, of whom eight are assigned to the manufacture of incubators, in one or two shifts. With the support of Manfred Parr, Roemheld assembly technology product


manager, Kämmerer and Pergande designed a line of four similar assembly work- stations arranged successively. Two of them are suitable for the assembly of the larger incubator models.
