Series 1500

The electronically (PLC) controlled 1500 series machines evolve from our well proven 500 (A&B) family of volumetric fillers - they are specifically designed for automated multiple head (in-line) filling applications requiring a high degree of versatility. Available in two, four, six or eight head configuration, these units are extremely robust, and suitable for filling most types of container in the range 50ml- 5 litres.

Precision bored metering cylinders up to 1200mm diameter (max 2.6 litre) may be fitted to two and four head machines - these enable efficient filling of containers up to 5 litre capacity with a double stroke, while retaining exceptional accuracy when filling smaller volumes. Product may be handled hot or cold, and volumetric accuracy is usually well within 0.5%. Due to the general compactness of the 1500A series frame, maximum metering cylinder capacity on six and eight head machines is limited to 800ml and 500ml respectively. A wider (1500C) frame is available for larger fills.

A single large pneumatic cylinder drives the metering cylinders via s system of levers and a heavy rocker shaft. Volume adjustment is achieved by controlling the stroke of this cylinder with a contra-piston, using a convenient manual adjustment or (optionally) an electric servo motor. The use of a contra-piston increases energy efficiency as the drive cylinder volume (and hence compressed air consumption) is reduced proportionally when filling smaller containers. An optional micro adjustment is available to provide a degree of individual adjustment to each metering cylinder. A secondary filling speed control may be used to slow down the fill rate as product level rises into the container neck.

All machines are manufactured to strict hygiene standards - wetted parts, manufactured from T316 stainless steel or suitable plastics, may be easily disassembled when in-place cleaning is not applicable. A range of non-drip shut off nozzles enables exceptionally clean filling of most products, with sub surface fill option available for efficient filling of foaming products. A unique (optional) side shift mechanism allows the nozzles to be positioned over a drip tray during container indexing, and also facilitates the use of neck guides for unstable bottles.

Product flow is directed by a large capacity pneumatically actuated rotary valve system flange mounted directly to the metering cylinders, allowing passage of viscous products - and products containing pieces up to 10mm across. Intake ports are connected to a hopper mounted to the rotary valve or, in some cases, directly to bulk supply via a manifold. Shut off nozzles are connected to the delivery ports via a flexible hose, which allows movement for adjustment to accommodate a wide variety of container dimensions - and for vertical and horizontal travel when B/U fill and/or side shift options are used.

The standard pneumatic gating mechanism enables efficient handling of most containers - an optional electrically driven star-wheel gating system is also available, which reduces shock and noise (and hence the risk of chipping or breakage) when handling glass containers.
