Counting scales are used wherever accurate counting is required, many scales have this function available based on the operator placing a small sample on the weigh pan (5,10,etc) then confirming the quantity, the scale computes the average piece weight (APW) and display the count additional items are then added to meet the packing requirements.
We recommend testing components before buying off internet, we stock a range of machines that we use prior to purchase to ensure you get the correct model..
Scales have a "minimum" weight that they will perform to and should be considered in counting for example ; A 15Kg x 5g scale has a minimum weight of 100g so if you have parts that are approx 5g then you will need a minimum of 20 + items to use as a sample, but if you try and count 1g items you will need 100+ items to use as a sample, so it's important to select a scale that has enough sensitivity and less capacity, we would recommended the scales minimum weight is considered to minimise the amount of sample required, after all counting 100 items is time consuming.
There are many ways to count, but only Counting Scales
offer the best combination of accuracy,
ease of setup, repeatability and cost benefits in the long term to your business,
All Counting Scales use the weight of a sample of parts to create an Average Piece Weight (APW)—the scale shows the count of the pieces on the pan by dividing the weight by the APW in memory.
Choose the Right Counting Scale
• What is the weight of the lightest part?
should equal the minimum APW of the scale and samples to test your scale prior to purchase is encouraged.
• How much do the boxes weigh (parts plus box)?
capacity of the scale should be 1.5 to ×2 the heaviest box, off centree loading can have significant implecations on accuracy
• How big is the largest box you will be using?
can range from 200mm" × 200mm" all the way up to 1200mm' × 1200mm', using platform scales or weigh beams
