Main Features

+ - General machine concept Click to collapse

Integrated ("all-in-one") counting-stacking-packing equipment for maximum process control and operability and for easy and fast installation & start-up.

Available as a standard for the packaging of products in pre-made bags supplied in wickets.

Full servo technology: all operating units driven by servo-motors for maximum flexi- bility in meeting different packaging format requirements and for fast changeovers.

Sturdy design, with all process units easily and quickly accessible through protective LEXAN covers with hinged doors. Stainless steel or surface coatings for all parts in contact with the product. Designed and manufactured in co-operation with Optima Filling and Packaging Machines GmbH.

+ - Product stacking section Click to collapse

Servo-motor driven product collection and re-pitch unit with anti-static and anti-wear flat belts, height adjustment system and product thickness control device.

Two servo-motor driven product twist belts with gap adjustment. Innovative design product infeed system: driven by linear motor, intermittently swinging for continuously feeding the product into the stacking paddle-chain, with the chain motion or still.

Product collection with dual ("top & bottom") paddle-chain for maximum control of collected products, servo-motor driven for high speed operation and with automatic product reject system.

Stack counting and delivery system with double driven "cartesian" unit for a linear stack extraction through still paddle-chain for high speed operation.

+ - Stack handling section Click to collapse

Servo-motor driven stack pre-compression unit with compression force up to 1,5kN.Two-axis servo-motor driven robot pusher to transfer the stack to the bag filling & sealing section. Designed to deliver single stack or dual stack formats.

+ - Bag filling & sealing section Click to collapse

Stack feeding system with servo-motor driven overhead carousel with pushing arms, supported on both machine sides and dual chain guided on cam tracks.

Stack compression unit with two, stainless steal, compression plates with air cushion, each operated by a servo-motor & crank system for maximum compression up to 25 kN.

Over-compression feature for easy compressed stack transport and bag filling. Rapid change over by means of spindles. All compression strokes easily adjustable via control panel screen. Servo-motor driven shuttle to transfer the stack from the main compression into the bag. Stainless steal shuttle plates with air cushion for a no-friction stack transfer.

Rapid change over by means of spindles. Servo-motor driven bag pick-up and opening unit with mechanical clamps for bag opening and holding and with vacuum system to help bag opening. Rapid change over by means of spindle. Servo-motor driven automatic bag wickets conveyor.
Servo-motor driven welding station designed for impulse sealing, with upper and lower welding bars, air-cooled and with individual temperature controllers and with vacuum film holding system for high quality seal execution. Mechanically operated side gussets folding poles. Pneumatically operated trim cut-off knife. Lower welding bar with exhaust slot for trim removal.

+ - Motion and processcontrol systems Click to collapse

Axis control modules, drives for servomotors, circuit switch and contactors, power supply, PLC and machine networking systems contained in off-line cabinets. Human Interface Module ("Touch-screen" Operating Panel) mounted on the machine frame, for centralized management of all machine operation phases.

+ - Safety Click to collapse

Safety features and protective covers comply with European EC Regulations. Machine supplied with Manufacturer's Declaration.
