Abstract

An egg grading machine is composed of many mechanisms of which functions are to carry eggs to the bucket in that sensors are located to categorize eggs by their weight, to transfer eggs from the basket of packer holder to the mold tray, to feed the mold tray dispenser after egg chairs are filled with eggs. This paper deals with the analysis and new design of packer holder mechanism of which function is transfer eggs vertically from the bucket conveyor to the mold tray dispenser. Egg is fragile to impact so in designing packer holder mechanism it is necessary to estimate moving speed, acceleration and impact when eggs are touched by any links of mechanism and mold tray dispenser. A new packer holder mechanism is proposed in this paper, which use quick return mechanism composed of 6 links with pin and contact joints.
