OKPack without a cap
The pack has gone through without a closure and must not leave the line.

Cap and closure inspection on every pack
A missing cap, one sitting high or skewed, or a broken tamper seal won't show up in the hourly sample. They show up if you look at every unit. With machine vision we check the closure of every pack at line speed, and any pack that fails is rejected along with its photo.
What it does
Inspects every closure and decides in milliseconds
A HIKROBOT smart camera looks at the closure of every pack and compares it with the recipe for that format. If any measurement falls out of range, the pack is rejected and its image is stored with the exact reason.
- Every pack, not a sample
- Photo of every reject, with time, recipe and reason
- Instant alerts by email, Telegram or WhatsApp to whoever you choose
- One recipe per format: a format changeover means loading another recipe
- IP65 and IP67 enclosures for wet areas
What we detect
The closure faults that reach the customer
These are the closure checks we install most often. If your defect isn't on the list, we'll run a remote feasibility test free of charge, using photos, videos or samples of your packs.
High cap
The cap is on, but it is not fully seated.
Off-centre or skewed cap
Centring and skew measured on every pack, against the threshold in your recipe.
Opening tab and tamper seal
That the tab is there and the tamper-evident seal is intact.
How it's built
Lighting, trigger and rejector, tuned on site
The camera sees, the trigger decides when, the recipe sets the verdict, the rejector acts and the log keeps the record. We tune it on your line, with real product.
- Lighting matters more than the camera: the lighting angle is what makes a badly fitted closure visible.
- A stable trigger: photocell at medium speeds; encoder when the line runs fast.
- Rejection on time: the delay depends on the distance and the conveyor speed.
- Thresholds with permissions: visible to the operator; only the quality manager and maintenance can adjust them, with user login and audit log.
The same inspection can also check the date and batch coding or the label and codes, depending on where they are on the pack. On bottles, the same station can also check the fill level; everything we inspect in this sector is in machine vision for beverages. A real example: code and cap on milk bottles, with the cap checked by deep learning.
FAQ
Answers to the most common questions
Which cap defects can machine vision detect?
Missing cap, high, off-centre or skewed cap, and the opening tab and tamper seal. All on 100% of packs, in line, with a photo of every reject.
Will it work with my packs?
We check first with a remote feasibility test at no cost: you send us photos, videos or samples of your good and bad packs (if a visit to your plant is needed, travel is charged separately). We tell you whether it can be detected in line, with which technique and with what reliability to expect; what cannot be guaranteed, we tell you up front.
What happens to rejected packs?
They are removed from the line, and every reject is stored with its photo, time, recipe and reason, available to quality and for any audit or complaint.
Do I have to stop the line to change format?
No. Each format has its own recipe, and changing over means loading another one, in seconds.

Can your closure defect be detected?
Send us photos of a good pack and a bad one, or real samples. We'll tell you whether it can be detected in-line and with what expected reliability. Whatever we install, we guarantee.
