Aseptic liquid filling and closing monoblock is ideal for precise and sterile productions, especially where frequent immediate changeover to many different products is required.

 

The AMT Monoblock has a very small footprint and will outperform functions that normally require employment of many separate machines. One AMT Monoblock can perform all of the following functions with minimal, no-tooling change parts and automatic servo height adjustments to different bottle heights:

• Liquid Filling
• Stoppering
• Crimp Sealing
• Screw Capping
• P&A Labeling

The Monoblock is equipped with a servo controlled, digitally compensated AMT Peristaltic Pump (see below) allowing for fill volumes from a fraction of 1 ml to 1 liter with better than 0.2% fill precision and production speeds up to 80 bottles per minute. Many nozzle configurations are available depending on volume and production speed requirements.

Effectively crafted, modular design allows for immediate changeover to different functions and various product sizes and shapes, with a minimal number of change parts. Production parameters and records are kept in the computer for immediate changeover, report generation, and easy validation, and are all accessible via the touch screen HMI. Components such as motors and belts are isolated below the fill area, providing assurance against particulate contamination. The Monoblock can be equipped with its own conveyor or it can operate from the customer's conveyor. Rotary tables, tray-loaders/unloaders, and a P&A Labeling Machine may be added for a total packaging solution.

AMT™ Servo Peristaltic Pump

The AMT Monoblock is equipped with a servo controlled, digitally compensated AMT Peristaltic Pump that 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.

 

Better than 0.2% fill precision is achievable. Volume calibration is immediate from the touch screen and can be performed without stopping production. AMT servo pumps have programmable speed and acceleration for optimum performance. Drip-less operation is obtained via a SuckBack system. Reversible flow and jogging are provided for system purging and priming. The pumps are suitable for CIP (Cleaning In Place). Tubing and bottom up nozzles are the only fluid contact parts. They can be disposable or disassembled in a few minutes for sterilization and reassembled with reduced risk for contamination.

• Disposable Technology
• Sterile - only tubing and nozzle contact the product
• From fraction of 1 ml to 1 liter programmable fill volumes
• Fill precision better than 0.2% based on product and speed
• Over 400 fills per minute production with Servo "Walking Beam" System
• Up to 80 fills per minute monoblock production
• 100 programs for immediate changeover
• SuckBack system for drip-less production
• Jog forward and reverse functions for priming and purging

The AMT™ Monoblock utilizes any combination of the following functions to aseptically and precisely package a variety of shapes and sizes of liquid containers.

Orienting and Feeding

Vibratory bowls orient and supply stoppers, plugs, orifices, screw caps, and aluminum crimp closures. Only a few change parts are used for a wide range of product sizes and shapes. The hopper bowls and tooling are made of 316 stainless steel and are easily removable for sterilization. Servo drivers automatically readjust vibratory bowls for pre-programmed bottle height.

Servo Changeover

Modular exchangeability and the uniquely programmable ServoChange™ dramatically reduces set up time and makes validation easy. Parameters and functions are computer recorded in pre-programmed production profiles. A desired product profile is called up with a touch of the screen for new production or for editing. A practically unlimited number of product profiles can be stored for immediate recall.

 

Rotary bottle indexing star-wheels have quick disconnects and are easily exchanged. The star-wheel servo driver has programmable acceleration for optimum performance. The capping chuck is easily exchangeable with a crimp sealing device. Servo drivers automatically readjust the AMT™ Monoblock and vibratory bowls for pre-programmed bottle heights. Nozzle top and bottom positions, fill volumes, calibration, speeds, accelerations, timing and other parameters are also automatically set by software.
