Automatic Packeting Machine

In many applications of packeting by count,the packets or envelopes are manually handled due to low volume (short runs with changes) or cost restrictions.
Longer product runs may permit using one or more counting systems to operate in conjunction with automatic packaging equipment to increase packaging rate and reduce labor input and therefore cost of packaging.
In the area of testing of new plant varieties, particularly in variety testing of corn, soybeans, cotton, and other crops raised in large volume, millions of paper packets are used annually all of which are manually opened, placed on the discharge chutes of counters, filled by count, removed, and closed.
Similarly, many conventional seed packets are being filled manually by small companies unable to afford expensive high speed filling equipment or where production runs are too short to justify operating this equipment.
The Old Mill Automatic Packeting Machine was developed to fill this need.


The Old Mill Packeting Machine will fill on a count, weight, or volume basis paper envelopes (coin type or seed packet) with seeds or small parts.
Envelopes move from a supply manifold (which may holdup to 400 envelopes)to a filling area for filling, then transferred to a closing area for closing, and are then re-stacked in a filled envelope manifold in the same order that they were stacked in the in-feed manifold.
The process is completely automatic, operating at a rate of up to 20 envelopes per minute although the rate is normally determined by how quickly the filling system can supply the required seeds or parts.
It can be adjusted to handle envelopes as small as 1-1/2 inches X 3 inches up to 4-1/2 inches x 6 inches as well as standard seed envelopes.
Envelopes are closed automatically after filling by stapling or by using the adhesive on the envelope flap (either a pressure or a water activated adhesive can be used).
Operation is by means of air cylinders for various mechanical actions, controlled by long life air valves and an electronic control system.
“Functional Module Construction” allows the operator to remove a malfunctioning module and replace it with a functional unit, thereby simplifying service and reducing machine downtime. This is simplified by a “help diagnostic program” which identifies the malfunction and suggests what correction action should be taken.

The Old Mill Model 850-3 Counting System integrates easily with the Automatic Packeting Machine for filling packets by count with seeds or small machine parts and operating on a completely automatic basis.
A high sensitivity Old Mill Electronic Scale unit is also available for those applications where the accuracy of filling by count is not required and weigh filling can meet the required fill accuracy.
An Old Mill “Smart Eectronic Scale” can also be supplied for seed packeting applications of packaging by count where high counts (500, 1000, 2000, or more) increases the time to fill the package to a very slow packeting rate. This unit includes a seed counter to periodically and automatically determine the count/weight relationship and adjust the scale to maintain the required seed count.
Infeed systems can be combined with the Old Mill Bulk Hopper to feed material to the infeed unit as needed, thereby reducing operator labor and increasing system operating rate and accuracy when a large volume of material is being packeted.
