Abstract [sv]

Denna rapport rapporterar ett examenarbete utfört av Ida Almér och Johanna Hed hos företaget EMBA Machinery AB. Företaget tillverkar konverteringsmaskiner för wellpapp. In i konverteringsmaskinerna matas wellpappark och ut kommer rillade, vikta och limmade wellpapplådor. EMBA’s maskiner ä såkallade inlinemaskiner som bestå av flera enheter. Den enhet som examensarbetet adresserar ä enheten uppräkningen. Uppräkningen är den sista enheten i EMBA’s maskiner och den har till uppgift att räna och dela upp wellpapplåorna i buntar.

EMBA ville att föfattarna skulle omkonstruera funktionen som delar upp wellpapplåorna, den såkallade delningsarmen, i den beröda enheten. Omkonstruktionen fö delningsarmen skulle styras via el-servodrift och fungera som ombyggnadssats fö tidigare maskiner.

Beräningar i syfte att undersöa vilka späningar som uppstå vid kritiska punkter i konstruktionen har genomföts. Röelseprofiler har tagits fram och dimensionering av motorer och väellåor har gjorts. Parallellt med detta skapades äen en 3D-modell i CAD. Utifrå CAD-modellen kan föetaget gåvidare med att skapa kompletta ritningsunderlag.

Abstract [en]

This report describes a bachelor degree project conducted at the company EMBA Machinery AB. The company manufactures corrugated cardboard conversion machines. The machines convert cardboard sheets into folded corrugated boxes. EMBA´s machines are so-called internal machines that consist of several devices. The unit involved in the thesis work reported herein was the unit Counter Stacker. The Counter Stacker is the last unit in the EMBA machines, it counts and divides the finished cardboard boxes into bundles.

EMBA wanted the authors to redesign the function that divides the sheets, the divider arm, in the affected unit. The divider arm should be controlled via electric servo operation and also act as a rebuild kit for previously sold machines.

Calculations to investigate the stresses that arise at critical points in the design have been carried out. Motion profiles have been developed and motors and gearboxes have been dimensioned. Parallel to this a 3D-model was created in CAD. Based on the CAD-model, the company can proceed with creating complete drawing documents.
