Paper and plastic cup visual inspection machines

Visual inspection machines for paper and plastic cup quality inspection, covering the rim, the seam, the print and the body in one pass.

What these systems do

A drinking cup fails at the places that touch the customer. The rolled rim can be uneven or cracked, the side seam can be open or misaligned, the print can be skewed or smeared, and the body can carry contamination, deformation or colour drift. On a line running hundreds of cups a minute none of that is visible to an operator.

These systems present cups to a multi-camera station with lighting designed for both absorbent paper stock and glossy plastic. The AI compares each cup against the accepted standard and rejects failures online, with counting and separation of accepted cups so the packing station receives clean product.

Because paper and plastic cups image very differently, the light source is specified per material at design stage rather than adjusted afterwards, which is the difference between a stable false-reject rate and a machine operators switch off.

Questions buyers ask about this family

Paper cups and plastic cups on one machine?

Both are supported by the platform. Tell us which materials you run so the light source is designed for the mix rather than for one of them.

Which defects are covered?

Appearance defects on the rim, seam, printed surface, body and base, including contamination, deformation, colour difference and print faults.

Does it check cup dimensions?

The system inspects appearance. Dimensional checks such as rim diameter can be included when they are visible to the camera, so raise them at the enquiry stage.

How is it fed?

Inline from your forming machine, or offline through a feeding device supplied with the system.

What happens to rejected cups?

They are removed online by pneumatic rejection. Accepted cups are counted and separated for packing.

What do you need to quote a cup system?

Cup samples including defective examples, the materials and sizes in your range, line speed, the smallest defect that matters, and whether the machine is inline or offline.
