The AMO Screw-Type Packer is a world-class machine. Innovative design and features are far ahead of other manufacturers. |
| The AMO Screw-Type Packer revolutionizes the powder-bagging worksite, which with other machines is a harsh, dust-filled environment for machine operators. Two internal screws combined with small quantities of compressed air are at the heart of the AMO method. This basic structure has been steadily improved over 40 years. The merits are acknowledged all over the world, as shown by the fact that some 4,000 units have been delivered in Japan and abroad. |

Features of the AMO Screw-Type Packer |
 |
Virtually dust-free |
The construction of the AMO Screw-Type Packer is such that the powder
has no direct contact with outside air. It is effectively semi-closed.
Moreover, the use of an expansion nozzle at the end of the nozzle
section seals the connection between nozzle and bag while filling.
The AMO Screw-Type Packer therefore raises almost no dust.
|
|
|
Prevention of contamination |
The semi-closed structure of the Packer essentially prevents unexpected
accidents such as foreign bodies entering the powder from outside.
Furthermore, components coming into contact with powder are designed
to maximum safety specifications to virtually eliminate the possibility
of machine elements dropping into the powder. Please ask us about contamination
prevention measures under HACCAP and ISO9000 series guidelines.

|
Compact & convenient |
The AMO Packer is extremely compact, at about 1.2 m wide, 1.8 m deep
and 1.9 m high. This machine is a flexible solution even in cases where
there is not much space for installation of the Packer and other machinery.
Because the Packer needs only an AC power source and a source of small
amounts of compressed air, it is ideal also for small-scale facilities.
|
|
|
Expanding to automation of bag placement & sealing |
As a total solution manufacturer, AMO designs and makes automated lines
including bag placer and sealing machines. For customers who installed
the AMO Packer and are planning to automate, we will take responsibility
for development of automated production lines.

High fill density with valve bags |
When filling open-top bags, the nature of the system makes it impossible
to raise the fill density. The shape of the filled bag is irregular,
and the lack of uniformity causes problems with packing on standardized
pallets. The AMO Packer uses valve bags and easily achieves a high
fill density. Automated palletization is thus no problem.

 Two
screw conveyors transport powder from the hopper to the nozzle.
Small quantities of compressed air sent to the nozzle force
the powder through the nozzle into the bag. This is the basic
structure of the AMO Screw-Type Packer. The screw conveyors
operate according to electronic quantity data collected by
the load cell. A two-step controller switches the Packer instantaneously
between high-speed and low-speed operation, thereby enabling
both high-speed filling and weighing accuracy. (A machine under
linear control is now being developed.)
The nozzle section has a rubber expansion nozzle which expands to a tight fit
on the inside of the valve while filling. This has the dual merits of stopping
the nozzle from slipping out of the bag, and preventing powder spillage.
The material, pitch and other specifications of the auger screw are selected
and coordinated according to the powder being transported. Furthermore, specific
surface-finishing of screws and cylinders, and other modifications, enable bagging
of powders with special properties, prevent contamination, and so on. |

Each machine is custom-made |
| We custom-build the auger screw and other
components for the AMO Packer. This enables us to provide
customers with machines ideally suited to their specific objectives. |

The Airless Packer range |
| In contrast to the standard AMO Screw-Type
Packer, the Airless Packer uses no air, only the screw, to bag powders.
This machine exercises its strength in filling airtight bags with
powders that have very high fluidity when mixed with air, materials
with extremely low fluidity, materials with adhesive properties,
and other powder types with special properties. |
