RILE had to realise the following automation solution: six different gear types with different diameters had to be taken from the conveyor belt that is associated with a Pfauter gearing machine and put into the inlet gutter of a Hurth deburring machine. Corresponding to the different six types of gears, the Hurth deburring machine had to be mechanically adjusted to the new types.

Our challenge regarding this project was: Modification according to the different types of gears at minimum material expenditure and time spent.

After a joint preparation of the job specification RILE's task was to design the turnover device and to prepare CAD-drawings. Moreover, we had to realise the automation, what means production and pre-inspection at our premises as well as implementation of the turnover device at ZF.

Procedure:
The existing Siemens S5-control of the Hurth gear deburring machine was used, the SPS-program was adjusted to the machine and the turning device integrated as new part of the production unit. For constructional reasons we decided to use hydraulic operators, as thus the handling device could be integrated in the hydraulic of the Hurth machine in a very inexpensive way. Thus, a new hydraulic or even additional control cabinets could be prevented and considerably costs could be saved.

RILE produced an automation component with a fixed interface for the existing machine, built it up, tested it and equipped it with the corresponding interface at the customer's premises later. As the turnover device, the electric and the program were tested at RILE in advance, a minimum standstill at both machines, the Hurth and the Pfauter, could be achieved.

In order to assure a quick change to the different gears, only interchangeable parts (pick up of the gears) are used as for work-piece changes. The turnover device itself consists of a construction of extruded aluminium sections, two hydraulic linear modules, a hydraulic swing module and a hydraulic gripper with part-specific mounting parts. A protecting fence and a manual operation device round this automation off. Operation manuals, training, assistance and service are not missed at this small automation solution, too.

Conclusion:
Being a service enterprise for automation solutions and rationalisation projects, RILE always tries to prepare existing production units for new tasks and to equip them with the necessary most modern technics at a minimum of expenditure.

Existing installations are newly designed according to our customers' demands. Moreover, this cells are offered as "system solutions" starting with design, electrical planning till production and start-up of the equipment.
