Linear Weigher

Fast, Accurate And Reliable Approach To Weighing A Huge Range Of Products

One Of The Most Cost-Effective Method For Weighing Bulk Materials To Relieve Labour Intensity And Improve Working Efficiency.
How the Linear Weigher Works:

The Linear Weighers feature fast, precise and accurate dosing. The dual head linear weigher design allows for easy integration with packaging machines to achieve the perfect package weight.The modular construction makes cleaning easy and keeps maintenance to a minimum. Various options are made available to meet specific requirements.

The Linear Weigher is set to a pre-determined target weight, the bulk product is then loaded into the in-feed hopper.
The product enters the weigh pan where the system monitors the weight, assisted by a vibrating mechanism (other methods of dosing available depending upon product such as an auger, belt feeder etc.).
Once 80% of the target weight has been loaded, the system switches to a dribble feed for the final 20%, thus ensuring optimum accuracy (the percentages of fast feed, dribble feed is configurable to specific products to allow greater throughput).
Once weighed, the operator depresses a foot switch or pushes the drop button and the product travels through stainless steel outlet chute. Electronic weighing and supervisory Programmable Logic Control (PLC) monitors the bag weight and controls the bag filling using a fast, then for improved accuracy, a slow feed phase.[/spoiler] [spoiler intro=”The Bags Contents Are Weighed By Gross Weight »”]Bradwood Packaging’s Linear Weigher weighing system uses a specially designed scale to achieve market leading performance. This technology is a key point of difference between our Packers and the competition.

A load cell is used on each weigh bucket, this allows accuracy and speed to be achieved. This process is ideal for small to medium speed packaging applications.

The Linear Weigher is an accurate preweigher designed to fill Confectionery, Frozen Foods, Snack Foods, Nuts & Pulses, Tea & Coffee, Dried Foods, Pet Foods, Dry Baby Foods, Seeds, Grain, Rice, Sesame, Melon seeds, Food additives, Sugar, Salt, Chicken essence, Pesticide, Fertilizer, into open mouth bags, jars, bottles or boxes.
