インライン検量機 | Food Industry Checkweigher | Inline Weight Inspection for Food Packaging
Food manufacturing is one of the most heavily regulated sectors in the world, and net weight is one of the most frequently audited specifications. A food industry checkweigher replaces manual spot checks with continuous 100% inspection, so every pack leaving your line has been verified against the declared weight.

Manual sampling fails in two ways. First, statistically: if you inspect one pack in fifty, you will miss a fraction of the underfilled units, and those packs reach the retailer. Second, legally: most food safety regimes treat the declared net weight as a legal claim, and a systematic overfill or underfill exposes the manufacturer to penalties and costly product recalls. An inline checkweigher removes both problems — every item is measured, and the result is recorded.

食品工場の衛生設計
A checkweigher sits in the middle of a food production area, so its frame is a food safety surface. Food grade checkweighers use SUS304 stainless steel with seamless welded joints, curved legs that leave no floor-level dirt trap, and quick-release conveyor belts that can be removed for washing. The design should avoid sanitary dead corners where food residue can accumulate, and the control cabinet should be sealed against splash and dust.
包装設備との統合
An inline checkweigher is normally installed after the primary packaging machine and before the cartoning or palletising station. It communicates with the packaging machine to synchronise product spacing, which is what makes accurate high-speed weighing possible. Verification results can be exported over USB or Ethernet so that production records satisfy retailer and third-party audit requirements.
食品検重機の選定
Give your supplier the lightest and heaviest product weight, the widest pack dimensions, the line speed, the required accuracy, and the reject direction. Ask for a dynamic accuracy figure measured at your actual speed rather than a static rated figure — the two differ substantially. If your line handles several pack formats, confirm the recipe count is large enough to avoid repeated reconfiguration during a shift.
よくある質問
Is dynamic accuracy lower than the catalogue specification?
Yes, and this is normal. Catalogue figures are usually measured under ideal laboratory conditions. On a real line, product shape, fill consistency and upstream machine vibration all affect the reading. Any reputable supplier will quote a dynamic figure measured at your speed.
How often does the machine need calibration?
With modern auto zero tracking, routine calibration checks are needed on a shift or monthly basis depending on your compliance regime, not daily. The key requirement is a stable zero, which the software maintains automatically.
Can one machine handle several food products?
Yes. Each product is stored as a recipe containing its target weight, tolerance and reject settings, and operators switch between them from the touchscreen.
