Retro­fit of a rotary machine in China

Task

The goal was to mod­ern­ize one exist­ing plant for the pro­duc­tion of halo­gen bulbs, which is in use in var­i­ous auto­mo­biles. The pro­duc­tion plant con­sist­ing of a sup­ply as well as a dis­charge con­vey­or belt, a rotary machine and var­i­ous qual­i­ty assur­ance units is oper­at­ed in Songzi (Chi­na) and is part of an auto­mat­ed pro­duc­tion line. Because the life­time of the com­po­nents exceed­ed and the con­troller was dis­con­tin­ued, the sys­tem should be brought to the newest state of technology.

Engi­neer­ing and project management

The engi­neer­ing and pro­duc­tion of the com­po­nents was done in Ger­many. All fin­ished parts includ­ing acces­sories for mod­ern­iza­tion were trans­port­ed to Chi­na by air freight. The project man­age­ment in the prepara­to­ry phase was coor­di­nat­ed from Stol­berg and con­tin­ued with the imple­men­ta­tion in China.

Elec­tri­cal modernization

The com­plete machine instal­la­tion includ­ing con­trol cab­i­net group and user inter­faces should be exchanged. An exist­ing vision sys­tem was adapt­ed to the new con­cept and revised. The prod­uct track­ing and oper­a­tional data acqui­si­tion was mod­ern­ized and inte­grat­ed into the new con­trol cab­i­net group.

Mechan­i­cal modernization

Old pneu­mat­ic actu­a­tors were replaced by bus-con­nect­ed valve ter­mi­nals, the pneu­mat­ic instal­la­tion was renewed.
