HIGH SPEED SERVO WALKING BEAM FILLER

The AMT "Walking Beam" System produces over 400 bottles per minute for up to 100 ml fills, and proportionally slower for up to 1 liter fills. System accepts various sizes and shapes of containers with rapid changeover. Fill tolerance can be better than 1% depending upon product, volumes, and production speeds. All movements - nozzle bottom-up and forward-back, feed screw synchronization and peristaltic pump are servo-programmable for smooth operation. The AMT Servo Peristaltic Pump will accept tubing from 1/16" ID to 3/8" ID for a range of fill volumes from a fraction of 1 ml to 1 liter and will allow for optimal compromise between fill volume, production speed and fill tolerance. Typically, 8 to 16 nozzles are used and the pump will accept up to 20 nozzles for higher production speeds. Pump is oriented for easy air purging, convenient replacement of product contact parts, and is ideal for disposable technology. Combine the Walking Beam Filler with Servo-Synchronized Stoppering for a state-of-the-art, high speed, sterile liquid filling and stoppering system.

HIGH PERFORMANCE INLINE LIQUID FILLING APPLICATIONS

Digitally compensated AMT Inline Liquid Fillers are equipped with a servo controlled, digitally compensated AMT Peristaltic Pump and are ideal for precise and sterile operations, especially where frequent immediate changeover to many different products is required. Fill volumes can range from a fraction of 1 ml up to 1 liter with productions up to 120 bottles per minute. From 1 up to 40 nozzles can be configured depending on the application.

The AMT Inline Liquid Filling Machine will accept containers of various shapes and sizes with a minimal number of change parts. Fill precision can be better than 0.2% depending on products and production speeds. Immediate changeover to hundreds of different products is achieved via programmable servo drivers. Production parameters and records are kept in the computer for immediate changeover and easy validation and are available with the touch of a screen. Components such as motors and belts are isolated below the fill area, providing assurance against particulate contamination. Filler can be equipped with its own conveyor or it can operate from the customer's conveyor.

AMT™ Servo Peristaltic Pump

The servo controlled, digitally compensated AMT Peristaltic Pump is freed from the alleged precision shortcomings of peristaltic pumps by digitizing and compensating the flow characteristic (EqualFlow™, US Patent Number 6,393,338). As disclosed in the Patent, the servo-driver varies the rotary stroke accordingly based on a digitized flow characteristic. The long term tubing wear is also computed for automatic compensation. This technique allows for achieving the highest dispensing precision, while maintaining all the benefits associated with using rotary peristaltic pumps, especially unlimited programmable fill volumes and sterile operation with minimal maintenance. The benefits of using AMT Digitally Compensated Peristaltic Pumps greatly outweigh those of ceramic piston or syringe pumps.

Bottom Up Nozzles

From 1 up to 40 nozzles are servo-programmable for top and bottom positions, acceleration, and speed to assure minimal product foaming and splashing. Precision nozzle to nozzle adjustment system is provided. Drip-less operation is obtained via the SuckBack system.

Linear Bottle Transfer

One feed screw for bottle indexing can work with a wide range of bottle sizes. Feed screws are equipped with quick disconnects for changeover to a new range of bottle sizes. Sensors for bottle tracking are incorporated. Feed screws have servo-programmable acceleration for optimum performance. As an alternative, a simplified bottle escapement system with bottle counters is also available.

Servo Changeover

Inline Filler is programmable via three-axis servo system for different products. Parameters and functions are recorded in the computer under preprogrammed production profiles. A desired product profile number is called with a touch of the screen for new production or editing. Nozzles top and bottom positions, fill volumes, calibration, speeds, accelerations and timing are programmed for optimal production.
