ABSTRACT:
In a volumetric bagging apparatus for dispensing a predetermined volume of particulate material, such as fertilizer, into a bag position on the apparatus for receipt thereof, a rotating drum fills a clamped empty bag until a magnetic cam comes into controlled magnetic proximity to a first magnetic proximity micro switch. As the magnetic cam passes by the first magnetic micro switch, the then filled bag is released. A second magnetic proximity micro switch may be provided which is positioned after the first magnetic micro switch in the direction of rotation of the drum, with the actuation of the second magnetic proximity micro switch disengaging the drive means for the drum and locking the drum brake, thereby completing the bagging cycle. In this manner, the improved volumetric bagging apparatus is indexed by magnetic actuation. The sequence of operation is initiated by the mounting of an empty bag on a filler spout which produces an actuation signal which releases the drum brake, engages the drum drive and locks the bag securing clamps, the drum rotating around and thereby filling the clamped bag until the magnetic cam comes into the aforementioned controlled magnetic proximity with the first magnetic micro switch. Continuous operation can occur if the next empty bag is in position before the second micro switch is encountered, the drum thereby continuing to rotate, the next bag being secured and the cycle being repeated.
