The latest and most successful step in the continuous path of innovation

is represented by the new GE PLUS III rotary packer generation

that distinguishes itself in the market for the very compact and modular

design with very high flexibility and expandability thanks to the modular

integration between mechanical parts and electronic control.

Ventomatic was the first manufacturer to develop a

microprocessor-based controller for filling and weighing

units on packers and the first to introduce the electronic

rotary packer in an industry that up until than had

only known packers with mechanical weighing system.

The GE rotary packer familyVentomatic is located nearby the historical town of

Bergamo (North-East of Milan, Italy), where are

concentrated all of its activities, from R&D to production

and assembly.Here our company started the production

of packing equipment in 1957. Since the Ventomatic

has been recognised for its innovative design and

for the originality of the solutions it has proposed to

the industry.

The encoder tracking system significantly simplifies

the packer and offers shorter and easier erection and

tuning and eliminates sources of possible malfunctioning.

The positions for each of the filling operations is quickly

and accurately set on the operator panel, eliminating the

need to physically position externally mounted mechanical

devices on the packer. Specific sequences of the filling

cycle (and their positions) can be set in relation to type

of product, empty bag size, etc.

GEV PLUS III - Vertical shaft impeller

PROCESS: Ventomatic introduced a new philosophy in packing technology with the vertical shaft impeller. The product feed flow

is in the same direction as the impeller shaft, and due to the blade design, the internal turbulence is minimised and the product

is completely centrifuged. The result is an optimal deaeration of the product itself and a minimum kinetic energy dispersion

means high filling performance.

GE PLUS III - Encoder

The sequence of the bag filling operations is defined by the peripheral

location of the bag on the packer during the filling cycle: empty bag

application location, tare location, bag disharge location, etc. During

the rotation and according to its location, the filling unit receives

the relevant commands.These points, on bag location, are normally

determinated by a complicated system of microswitches, solenoid

valves, pneumatic cylinders etc., all mounted on the external

perimeter of the packer.

Ventomatic packers, however, fulfil the same operations with an

encoder mounted on the top of the rotating shaft of the packer. It

continuously tracks the angular position of the packer and, via a field-

bus connection, the information is sent to the filling units that react

accordingly.

GEO PLUS III - Horizontal shaft impeller

PROCESS: The filling device configuration with a horizontal shaft impeller represents the traditional solution for packing powder

products. It is a still valid solution for special types of cement and products with a particle size distribution up to 2 mm. Special

execution is available for particle size up to 5 mm with special lined impeller and guillotine.

GE PLUS III - Modularity and flexibility

A Ventomatic packer is composed of a number of pre-assembled modules, which are prepared and tested before delivering.

These modules are quickly and easily mounted on the central tank of the packer during the erection.The numbered pneumatic

connector plugs and electric rapid connectors avoid the possibility of erection mistakes.

If required and in order to minimise the initial investment, it is possible to put the packer in service with a reduced number of

bag fitting units. In case of future growth in production demand, additional filling units can be easily added on.

GEO PLUS III - VENTODIGIT EWU

Ventomatic has been a pioneer in manufacturing electronic packers since 1980, and with our Ventodigit III, Ventomatic has

achieved the objective of introducing a new all-in-one electronic unit.

The new weighing unit is based on the vast experience gained from our packer installations worldwide. Every filling spout is

controlled by the new electronic weighing unit VENTODIGIT III (EWU/010).

GE PLUS III - Network

All filling units on the rotary packer are connected to a data network CANBUS. Through a the unique Ventomatic Magic Box

device, all the weighing units are also connected to the absolute encoder for tracking their angular position and to the operator

panel. The operator panel, and the remote control system Ventolink III, receive in real time the complete status of each bag

filling unit and also its weighing performance. Furthermore, all filling units can be completely programmed from the operator

panel.

The MAGIC BOX device consists of infra-red optical communication system specially

developed for high speed data communication in heavy industrial environments.

It is 100% dust proof and not sensitive to any kind of vibrations or EMC noise.

Furthermore, there is no mechanical wear.

A real-time monitor and basic production

statistic page of the Ventocheck III is always

available on the operator panel display.

Operator panel

Ventocheck III completes the packing process and improves

the overall control by providing the following main functions:

• Sorting of broken bags, underweight and overweight bags

• Providing overall production data

• Monitoring each bag single filling unit performance on the

packer

• Adjusting automatically the set- point of each filling unit

on the packer (correction “spout-by-spout”)

See “Important Note” below

• Disabling automatically a filling unit in case of malfunction

or mechanical problems

IMPORTANT NOTE:The packer GE-PLUS III is able to achieve the target weight

performance without necessarly using the feedback from

the belt weigher.

GEO PLUS III - VENTOCHECK FEEDBACK

The belt weigher Ventocheck III can be directly connected, without using external master or other additional device, to the packer

operator panel and then to all the filling units on board.

GE PLUS III - OPERATOR PANEL

The achievement of greater flexibility and higher level of

automation requires an operator panel quite different to

the conventional pushbutton desk. The HMI (Human

Machine Interface) presents is an IP65 industrial graphic

terminal designed for industrial use and dusty environments

which thanks to a dynamic mimic of the packing line,

provides a clear and detailed overview and monitoring

of all the main equipment.

All the main operations such as start/stop of the line, change of product and bag size, emptying and cleaning of the

line, are completely automatic and programmable.

The overall feeding and packing process is monitored

with the possibility to adjust/optimise the performance

through specific pages of the HMI (protected by different

password levels) such as adjusting timers, variables and

abilitations of the PLC program.

Furthermore, all alarms and warnings are recorded,

facilitating troubleshooting and supporting preventive

maintenance planning.

The system is composed of three main parts:

• Supervision line module

• Shift setting module

• Statistical and reporting module

SUPERVISORY MODULE:The basic configuration of this module provides a real-time monitor of the status of the packer and the belt weigher including

actual production recipes, current bag weights, alarms and warning signal tracking and recording. Furthermore, the “recipes

management function” allows the remote setting and tuning of all the working parameters of the packer and the belt weigher.

In case other Ventomatic equipment

is installed (such as automatic empty

bag feeder, bag applicators, automatic

truck loaders, palletisers, it is also

possible to add an expansion module

for their monitoring.
