230 Series Auger Packer
19 OF 115
PRINCIPLE OF OPERATION
An auger feed assembly is the main feature of the Model 230 Auger Packer. The auger housing receives
bulk product from a surge bin and supplies a steady stream into the bag utilizing a flighted auger screw.
High-pressure air (80 PSIG), operates the solenoids and cylinders.
Bags are weighed during the filling operation on a unit consisting of bag support frame and filling tube
mounted on the front of a scale beam. Filled bags are discharged automatically when the machine is
equipped with an automatic discharge bag chair arrangement.
All of the operation activity for each bag filling cycle takes place in a matter of seconds. This packing
speed is important, not only to achieve high production rates and bag accuracy, but also for proper
function of the Model 200 Auger Packer
SEQUENCE OF OPERATION
A representative arrangement of the packer is shown below. It serves to amplify the following
description of a typical; TWO PHASE operational sequence for filling a bag. It should be noted, however,
that a variety of constructions are optional for the Model 200. The sequences as drawn shows the
optional timed powered discharge and timed bag sealer.
PHASE ONE
(Bulk and Dribble)
Phase One is the condition the machine is in at the end of a filling cycle or if the Stop (or scale)
pushbutton is pressed. This is what occurs:
Controller reaches final preset target weight.
The motor drive assembly and agitator stop and the auger reverses.
The material from the product surge bin stops flowing into the packer.
The bag clamp releases the bag.
The bag is discharged from the machine (hand or automatic). Since the material is moved by gravity
flow, the supply of material to the machine is continuous.
Various optional features shown on the schematic operate as follows:
The valve sealer deflates at end of filling cycle - this can be timed to ensure material stabilization in the
bag.
