Sports Drink Cap Check

Posted in Featured, Flaw Detection, Food & Beverage, Inspection, Object Location, Other, Presence/Absence

The Challenge: The machine vision system needs to check that all of the sports bottle caps have been assembled correctly, at a rate of 100 bottles per minute. Defects can include misformed, misaligned or missing caps, and kinks. The solution also needs to cater for multiple variants and needs to be able to suitable for a food grade (wash-down) environment. Our Solution: A turnkey, IP65 machine vision solution was installed to check every bottle ‘on the fly’, at a rates of up to 120 bottles per minute. The vision system checked for cap presence, position, and shape. The system was also integrated to a PLC which operates a reject mechanism, thus providing containment of defective products. Images of any defects are stored on a server with a date and time stamp, they are also displayed to the operator to help...

Bread Inspection

Posted in Colour Inspection, Diffuse Dome Light, Featured, Flaw Detection, Food & Beverage, Inspection, Presence/Absence, Uncategorized

The Challenge: Our customer wanted to be able to check the colour of every loaf to ensure that the ‘bake time’ was correct. The loaves exit the oven in batches of 12 tins.  The customer wanted to introduce a ‘closed loop’ system whereby consistent under or over baking adjusted the conveyor speed through the oven in order to compensate accordingly. Our Solution: A high resolution, colour area scan camera was installed along with diffuse LED lighting. The colour of each loaf in the batch is analysed and based upon statistical trend analysis the control system PLC adjusts the line speed as required. Additionally, individual loafs which fall outside acceptable colour limits are rejected from the line downstream. If more than 5 consecutive loafs are rejected the camera sends an ’emergency’  signal to the PLC so that the operator knows there was a major problem on the...

Barcode Reading

Posted in 1D Barcode Reading, Featured, Food & Beverage, Inspection, OCR (Optical Character Recognition), Part Identification

The Challenge: A printer generates a product label ready for application onto a product. Prior to application, each label needs to be inspected to ensure that the print quality and the information  printed is of suitable quality and correct. The labels index at a rate of 2 per second. Our Solution: A high resolution camera system was employed to read the label information using OCR (optical character recognition) and also to grade the barcode to the ANSI standard. Labels with either incorrect, partially missing data or poorly graded codes are marked by an inkjet marker and removed from the line prior to...

Fish Finger Inspection

Posted in Colour Inspection, Direct Bright Field Illumination, Featured, Food & Beverage, Inspection, Precision Measurement, Presence/Absence

The Challenge: The customer needed to check that every fish finger had the right amount of breadcrumb coating, that it was the right size, and was not deformed in any way.  These travelled down a 600mm wide conveyor at a rate of 100mm/second.  If a predetermined quantity of rejects are detected within a period of time then the system needs to be able to stop the line. Our Solution: A high resolution colour camera was used to inspect the entire width of the conveyor. Each fish finger was measured to ensure it was the right shape and size, and the coating of each was checked by checking the colour of it’s surface. All of the information collected was displayed on a screen on the side of the line and if the “critical” number of defects were  detected the line...

Food Label Reading

Posted in 1D Barcode Reading, Featured, Food & Beverage, Inspection, OCR (Optical Character Recognition), Part Identification, Uncategorized

  The Challenge: Product information is printed directly onto the outer case of food products as they travel down a conveyor at a speed of 10m/min. The information contains a barcode, the product’s weight, best before dates and the price. All of the information needs to be read and checked against the database and weight sensors situated on the line. Information on the product type is contained within the code, which also needs to be checked. All data needs to be logged in a database located on the network for future traceability. Our Solution: A complete turnkey solution was provided to the customer to be able to read, verify and record the information contained in the printed information....

Hot Cross Bun Inspection

Posted in Colour Inspection, Direct Bright Field Illumination, Featured, Flaw Detection, Food & Beverage, Inspection, Lighting, Object Location, Presence/Absence

The Challenge: Each tray of buns needed to be checked to ensure that the “crosses” were present (and in the right place and the right size) and that the bake was right (by checking the colour of the buns). All the information needed to be displayed to the bakery manager, in his office, and to the operator on the line so they could change the settings on the oven if they we’re not correct. This needed to happen at a rate of  6m/min on 600mm wide conveyor. The Solution: All buns were inspected successfully with a colour machine vision system. The camera were connected directly to the factory network so the images and results could be displayed to the bakery manager, and on a large display right next to the production line. Additionally  all the pass/fail images are stored on the network for production analysis at...

Pack Reading

Posted in 2D Datamatrix Reading, Direct Bright Field Illumination, Featured, Food & Beverage, Inspection, Lighting, OCR (Optical Character Recognition), Packaging, Uncategorized

The Challenge: Each pack has a label printed and applied to it and the 2D barcode and expiry date of each code needs to be read as the pack passes down a conveyor at a speed of 8m/min. The 2D code needs to be checked to ensure it contains the expiry date that is also printed on the pack. Information on the production / batch run is also contained within the code, this needs to be logged in a database located on the network for future trace ability. Our Solution: A complete turnkey solution was provided to the customer to be able to read, verify and record the information contained in each label....

Cap Alignment Inspection

Posted in Back Lighting, Colour Inspection, Diffuse Dome Light, Featured, Flaw Detection, Food & Beverage, Inspection, Precision Measurement, Presence/Absence, Uncategorized

The Challenge: After bottles exit the filling line, the lids are screwed on each one at rates of up to 100 bottles per minute. The vision system needed to be able to operate in a wash down environment (ideally at least a IP65 system) and for each bottle the checks it carries out need to include: – that there is a bottle cap present – that the bottle cap has been screwed on properly (ie completely screwed on correctly and not cross threaded) – that the bottle cap has no significant defects in it. The system needs to trigger a reject station and let the operator know that a defect has been detected. Our Solution: A self-contained IP67 rated, stainless steel vision inspection solution to check every bottle cap ‘on the fly’, at a rate of up to 120 bottles...

Cashew Nut Colour Inspection

Posted in Colour Inspection, Diffuse Dome Light, Featured, Food & Beverage, Inspection, Presence/Absence

The Challenge: The customer was having problems with the nut roast time (under / over cooking) and they needed a system to be able to monitor it. The nuts travel through an oven on a conveyor and the roasting can be controlled by either the temperature of the ovens, or the speed of the conveyor (to reduce errors, the bake is controlled by the conveyors only). Initially they wanted the system to run independently of their ovens / conveyors but ultimately they would like to create a closed loop whereby the systems could connect directly to the conveyors, whereby consistent under or over baking adjusted the conveyor speed through the oven in order to compensate accordingly. Our Solution: A high resolution, colour area scan camera was installed along with diffuse LED lighting. The average colour of the roasted nuts is analysed and based...

Tin Can Label Inspection

Posted in Featured, Flaw Detection, Food & Beverage, Inspection, Object Location, Presence/Absence

The Challenge: The cans (which are produced at a rate of one per second) have a label wrapped and glued around their circumference. Potential errors that can occur during this process include the label not being wrapped correctly (skewed, torn or completely missing), a second wrapper trailing behind the can (which should have been wrapped on the following can), or the wrong label being used. The vision system needs to be able to detect all of these defects, log them on the network, and display them to the operator working on the line. Our Solution: A turnkey vision system was created to identify any label defects. This connected to: – a reject station that removed the defects from prodcution – the network where is stored any failed images (with a date, time and production line stamp) – a display...

Sweet Inspection

Posted in Back Lighting, Colour Inspection, Featured, Flaw Detection, Food & Beverage, Inspection, Lighting, Presence/Absence

The Challenge: A sweet manufacturer wanted to check the shape and colour of boiled sweets that they manufacture. They also wanted to check for any inclusions or defects that may have occurred during manufacturing. The sweets are being manufactured at a rate of 8 per second. The machine vision system will need to operate in a wash down environment so its important that the system is at least IP65 (ingress protection rating). Our Solution: A high resolution Stainless Steel, IP67 vision system was mounted directly above a backlight that was integrated into the conveyor system. The vision system inspects the sweets for the shape, colour, chips and inclusions and is connected directly to a reject station which automatically rejects any sweets that don’t pass the...
