Every pack weighed, nothing learned
The checkweigher on each line rejects underweight packs, which is what everyone watches. Overweight packs sail through. The machine logs every weight, but the log stays on the machine, or goes to a USB stick once a month, or prints on a roll of paper in the line leader's office.
Meanwhile the filler on one line has been set a little generous since a changeover last month, and every pack carries a bit of free product. Nobody knows, because nobody is looking at the data in a way that shows it.
Why giveaway stays hidden
Target weights and tolerances are set by your technical and quality team, and the checkweigher enforces the lower limit. Giveaway is the other side, and it is an operational and financial measure, not a safety one. It falls between departments.
- Checkweigher data is not exported routinely.
- Different makes of checkweigher store data in different formats.
- Giveaway is reported as a percentage, which nobody feels, rather than product and money.
- Line settings change at changeovers and are not recorded.
- Finance sees yield variances without knowing where they came from.
What it adds up to
Product given away is ingredient cost that never reaches a selling price. On a high-volume line, a small overfill per pack can add up to a large amount over a year, but we will not put a number on yours: the point of the reports is that you see your own figure. It also makes yield conversations with finance guesswork, because nobody can separate giveaway from waste and process loss.
The giveaway reports we build
- We collect weight data from each checkweigher, using the maker's export, network interface or file drop, depending on the model.
- Each pack weight is matched to the product, line, shift and batch running at the time, using your production records.
- The target weight for each product comes from your specification, as set by your technical team.
- Giveaway is calculated as the weight over target, then converted into product quantity and ingredient cost using your recipe costing.
- A dashboard shows giveaway by line, product and shift, with trends over time and changeovers marked.
- Line leaders see a simple live view per line, so a drift can be spotted and corrected during the shift, not a month later.
| View | For |
|---|---|
| Live average over target per line | Line leaders during the shift |
| Giveaway by product and shift | Production managers weekly |
| Giveaway in ingredient cost | Finance and operations |
| Before and after changeovers | Engineering and setup checks |
We do not change target weights or tolerances. Those stay with your technical team.
What you can do with the numbers
Production managers can see which line and shift drift, and whether it follows a changeover or a particular setting. Engineers can check filler setup after maintenance. Finance can separate giveaway from other yield losses. And the conversation moves from a feeling that a line runs heavy to a figure that everyone can see.
It also helps with products that are hard to fill evenly, such as ready meals with pieces, mixed salads or bakery items with natural variation. The data shows which products carry the most spread, which is useful when engineering is deciding where a filler upgrade or a multihead weigher would pay back, and when commercial is deciding whether a pack weight is realistic.
Is this your factory?
- Checkweigher data stays on the machines.
- Giveaway is not reported in money.
- Yield variances are hard to explain at month-end.
- Filler settings after changeovers are not checked against data.
- Line leaders only watch the reject count.
