Easylink+ automatic coupling stations

Simple, reliable, efficient

To guarantee perfect cleaning of the main arms and prevent contamination, the new Easylink+ series is fitted with a state-of-the-art cleaning system integrated in the bottom inlet. Its new main arms are manufactured with a special hardening treatment for even greater wear resistance.

Even for the largest models with 60 inlets/outlets the floor space requirement is minimal. Easylink+, with its compact, vertical design with moving parts makes it inaccessible, for optimal operator safety. In applications where absence of contamination is critical, an optional slide gate can be installed on every outlet as a barrier against residual granules. To ensure correct selection of the material source, pneumatic fitting positions are encoder-controlled, while the drives are equipped with inverters for fast, precise movements.

An Easylink+ coupling station can control up to 60 sources and 60 destinations, and can be configured to use some or all of the inlets and outlets, with the option of subsequent expansions.

Easylink+ is essential for reliable, complete material traceability.

Integration with Winfactory 4.0 means:

  • maximum materials traceability
  • automatic setting of transport and line cleaning times
  • raw material stock monitoring with automated re-order function
  • remote connection from portable devices

Benefits

  • No contamination thanks to state-of-the-art pipe cleaning procedure
  • High wear resistance
  • Simplified maintenance
  • Completely traceable materials
  • Minimal floor space occupancy and maximum accessibility
  • Outstanding versatility thanks to a wide range of diameters – 40mm, 50mm, 60mm, 76mm – and the large number of possible inlet/outlet combinations

Handlink manual coupling stations

Quick and easy operations

Handlink is a manual coupling station fitted with innovative twist couplers based on a bayonet connection. Its differentiating feature is the absence of a gasket that could get in contact with plastic granules, possibly leading to contamination. Besides, any risk of decreasing the feed system performance due to the loss of vacuum is thus prevented. The new couplers of Handlink, ensure that stainless steel is the only material in contact with the plastic chips.

The connecting procedure is quick and easily performed with only one hand. If required, the basic version with brass threaded couplers and without a tagging system is still available. The Handlink+ incorporates a tagging system based on RFID system that includes a local LED to show the status of the connection immediately.

The tagging system facilitates a preliminary consistency check. If the Easy 3+ feeding system control detects an incorrect connection between source and destination, the feeding cycle will not start, thus avoiding any mistake or risk of contamination. The Handlink+ tagging system also introduces the function of cap recognition.

This additional feature prevents missing feeding cycles due to open material lines. In case there is a missing cap, a specific alarm is triggered and the operator can take the corrective action without any risk of compromising the overall performance of the feeding system. The new tagging system is meant to be fully integrated with the Easy 3 and Easy3+ controls, but special versions can be made for customized feeding system with PLC control.

Benefits

  • one hand connection and operation
  • absence of any sealing in contact with material, avoiding contamination risks or losing vacuum due to sealing wear
  • indication of the correct coupling thanks to RFID tagging system, avoiding mistakes
  • detection of the presence of closing caps

Varyo series vacuum units

Controlled vacuum generation

Varyo, a line of vacuum units for resin conveying, automatically adjusts loading cycle stages to eliminate mechanical stress on the polymer and to cut down electricity consumption.

Central vacuum units are in constant operation, whether on duty or on stand-by. Varyo can start and stop as required, without compromising life expectancy and reliability of the blower/pump or the motor drive. Resin conveyance puts the material under mechanical/physical stress, resulting in the generation of powder. What can be achieved with Varyo is the adequate velocity of conveyance in the pipe. Depending on the distance, elevation and quantity of material to be conveyed, Varyo can be set to generate adequate vacuum to perform the very initial phase of the loading cycle, when the material starts to move, the intermediate phase, when the material must fill up the vacuum receiver and the final phase, when the line must be purged. These phases require different vacuum levels in the line for different periods, depending on the length, elevation and capacity.

Benefits

  • Energy efficient operation
  • Reduction of dust generation
  • Adjustment of vacuum for individual receiver
  • Ordinary maintenance cut by 50%
  • Applicable to any Piovan central resin conveying system (Easy3 or central resin conveying systems with PLC control)
  • Optimized short and long distance material conveyance. Depending on the distance to the storage area, Varyo optimizes all operation parameters, including energy utilization to convey the material

Pureflo receivers

PureFlo eliminates the need for regular maintenance of the vacuum receiver (filter cleaning) and improves the conveying capacity of the whole system.
An airflow generated at negative pressure by a vacuum unit carries plastic granules through the conveying pipes.
Plastic granules are conveyed at a speed of 15 meters/second at the pick-up point and 25 meters/second at the end of the line.
In a conventional technology, plastic granules enter the receiver at the end velocity, i.e. 25 meters/second, and stop by hitting the inner walls of the receiver body.

The innovative and unique design of PureFlo allows plastic granules to dissipate the entire kinetic force picked up during conveyance, through a right angle bend, instead of keeping their end velocity all the way into the receiver body.
Granules fall into the receiver body, with a residual speed of 1 meter/second. The flow is directed to the base of the receiver where the air gradually loses pressure and velocity.

Benefits

Simple

  • No plugged filter problems
  • Simplified accessibility
  • No maintenance
  • Minimized cleaning

Efficient

  • Improved loading capacity
  • No cleaning cycles
  • Abrasion resistant
  • No powder pollution

Cost-effective

  • Minimal installation costs
  • No spare parts
  • Reduced cleaning activities
  • No maintenance downtime

Ryng production monitoring

Universal device for production monitoring

This is an extremely simple system which measures productivity and efficiency of the feeding line.
In order to obtain an instant and precise measurement of the quantity of material transferred from the container to the hopper, enabling operators to take prompt action on the machine’s operating parameters and, above all, to get information on the machine’s effective productivity, Piovan has designed and manufactured a special production monitoring system, called “Ryng”.

Ryng is structured as a component to be inserted between the loading container and the storage hopper with a high-precision weighing device placed inside it.
The system operates on a proprietary software, set according to specific algorithms which “filter” and “interpret” the data it gathers and consequently indicate the actual quantity of transferred material. Ryng in fact measures the quantity of material loaded into the hopper by the container, providing information straight from the field, thus allowing real-time comparisons to be made at any time between the machine’s expected and its actual production.

Moreover, the software is programmed to exclude or minimize any measurement fluctuations that may be caused by the inevitable vibrations felt throughout the feeder system as a result of the machine’s normal operation. In this way, the system achieves high precision measurements (with a maximum error rate of less than 1%).

Benefits

  • Monitoring material consumption in real time
  • Control of the production batches
  • Production volumes statistical data
  • Applicable with any loader device
  • Remote control via Winfactory 4.0 connection

ENERGY EFFICIENCY

Energy efficiency is a concept that in our part of the world became important towards the end of 2008 and the beginning of 2009, at the outset of the world economic crisis. Most business people had, until then, mostly declaratively considered power consumption as a significant element of the total cost analysis. In these considerations, the impact of energy efficiency on the environment pollution had hardly been tackled at all.

Neofyton was among the first companies in Serbia and the region to start actively demonstrating the importance of energy efficiency, both by cutting production costs and therefore increasing profit rates and building awareness of the resource shortage and broader ecological principles.

Energy savings through the use of Neofyton's machines

In comparison with our direct competitors in the field of plastics injection machines, and with the utilization of standard hydraulics with integrated so-called "smart" pumps, our machines consume as much as 50% less energy. The use of servo-hydraulics opens up the potential of savings as high as 70%. We have a very precise power consumption measuring device to prove this.

The company Engel was the first plastics injection machine manufacturer back in 2009, which introduced the power consumption page as a standard component of the control assembly – "Ecograph", where - next to the weight of each product (molded part) in every cycle - total hourly consumption is shown, as well as the specific power consumption per one kilogram of processed plastics (kWh/kg).

ENVIRONMENTAL PROTECTION

The equipment we represent contributes to ENVIRONMENT PROTECTION in several ways.
When it comes to ancillary equipment, above all water chillers by our supplier Eurochille, used for temperature control of both hydraulics and machine servo motors and molds (tools) in which finished products are made, the chiller systems we sell facilitate the use of a new cooling system based on the so-called "adiabatic effect".

In summer, the hydraulics and servo motors of the injection molding machines call for cooling with water at a maximum of 28°C. Using the so-called "free cooling" device with the "adiabatic effect", cooling of process water is performed without cooling compressors (which use freon as the heat exchanger). Heat exchange, i.e. cooling happens exclusively by the use of ventilators, which translates into six- to eightfold savings compared to traditional chillers that use freon-based compressors.

One of our customers has reduced the required cooling energy by 1.400.000 kWh per year, i.e. by about 70.000 EUR, using the "adiabatic" cooling devices. An additional benefit is the elimination of major pollution risks which might arise from emissions of freon into the atmosphere due to tube puncture or breakage.

A similar calculation can be applied to our Engel injection molding machines, as well as to the Piovan granulate dryers.
