Success Story

Retro­fit of a mount­ing automat

Com­par­i­son of the sta­tus before and after car­ried out modernization


The tar­get was the com­plete mod­erni-zation of a stock plant for the pro­duc­tion of seal­ing cov­ers of the dri­ve shaft man­u­fac­tur­ing. The plant arose in the eight­ies. The life­time of all com­po­nents was exceed-ed and it becomes nec­es­sary to update the plant to the best avail­able technology.

Mechan­i­cal modernization

The equip­ment was decon­struct­ed in all sin­gle parts and all wear parts of the plant (jour­nals, con­nec­tors, seal­ing gas­kets, gear rings and guid­ing shafts) were replaced. The exist­ing plant lubri­ca­tion was changed to a semi-flu­id lubri­ca­tion with dis­trib­u­tors. By using new cylin­ders and cor­re­spond­ing valve con­trols the pneu­mat­ic sys­tem was mod­ern­ized all around. A high­er plant dynam­ic was achieved by using ser­vo drives.

Elec­tri­cal modernization

It becomes nec­es­sary to replace the elec­tri­cal plant instal­la­tion includ­ing switch­board cab­i­net and ser­vic­ing lev­el com­plete­ly. All safe­ty func­tions were real­ized by the use of safe­ty con­trol and cor­re­spond­ing dri­ve con­trollers. Via transpon­der tech­nol­o­gy the manip­u­la­tion of mov­able guards was pre­vent­ed. An image pro­cess­ing sys­tem was applied for the qual­i­ty con­trol of dif­fer­ent prod­uct types.

Process opti­miza­tion and visualization

Via visu­al­iza­tion tai­lored to the plant an oper­a­tor guid­ed con­trol as well as an opti­mal process super­vi­sion of all plant con­di­tions were realized.

CE and dokumentation

Based on the new con­for­mi­ty dec­la­ra­tion of the plant it becomes nec­es­sary to pre­pare an exten­sive doc­u­men­ta­tion includ­ing risk eval­u­a­tion accord­ing to appen­dix VII of the EC machin­ery directive.
