This is a layout for a "SCALE (weighing machine)" that is installed on a stage where the stage is setup as to cover the packaging machine.
It is structured so that after a set weight of the products is weighed, it drops directly down from the scale to the packaging machine.
It is the simplest layout since there is no need for a conveyor between the scale and the packaging machine.
Although the floor space for installation is small, the height requirement is quite significant.
Most of these devices are circular and have multiple weighing hoppers aligned along the circumference. With the mutual combination of the hoppers, the value closest to the desirable weight is calculated and sent out for the products that are optionally entered.
It is very useful in particular to improve the unit weight yield rate of relatively heavy products. (There are also rectangular types and those with hoppers horizontally aligned)
