ABSTRACT:
BACKGROUND OF INVENTION
This invention relates in general to packaging apparatus and deals more particularly with an improved seed packaging machine for filling and closing preformed seed packets.
Such seed packaging machines of the aforementioned type as have been heretofore available are generally complex mechanisms designed for low speed operation, operate with intermittent motion, and have large numbers of moving parts. Such machines are generally expensive to produce, operate and maintain, are subject to heavy wear, and usually require frequent adjustment, which adds substantially to machine operating cost.
Accordingly, it is the general aim of the present invention to provide an improved seed packet filling and closing machine which may be produced at relatively low cost, and which is designed for continuous high speed, maintenance free operation. It is a further aim of the invention to provide a machine which may be readily adjusted by an operator having ordinary skill to accommodate frequent changes in seed feeding requirements with minimal machine downtime.
SUMMARY OF THE INVENTION
In accordance with the present invention an apparatus is provided for filling and closing preformed seed packets which have front and rear panels connected together along bottom and side edges, an upwardly open mouth and an upwardly extending closure flap connected to an upper edge of one of the panels. The apparatus comprises a supply magazine for containing a quantity of packets, packet feeding means for withdrawing each successive packet from the supply magazine and disposing it in a pick-up position, first conveying means for engaging each successive packet at the pick-up position, gripping an associated lower portion of the packet, and continuously advancing the packet along a predetermined path to and through a packet filling station. A packet opening means mounted in fixed position along the predetermined path opens the packet as the packet advances along the predetermined path to the filling station. Seed dispensing means at the filling station load a predetermined quantity of seed into the packet through the mouth thereof as the packet is advanced along the predetermined path through the filling station. A packet closing means is provided for closing the closure flap as the packet is further advanced along the predetermined path from the packet filling station.
