Beverage can making process: Training videos (Part 6)
This upload completes our series of videos that show how a beverage can is produced. Testing for internal defects and palletizing are both covered in this post. The idea of these videos is to help those who are new to the industry to learn about can making. Videos are courtesy of Ball Packaging Europe.
Part 13: Testing for internal defects
This test is a continuous 100% test of the inside of the can. It is performed by a CCD line scan camera system comprising five cameras.Camera number five monitors the end and the lower section of the can. Cameras one, two, three and four concentrate on the respective internal section of the can allocated to them.
The images from the five cameras are compared with a specified image in the computer system connected downstream. As soon as one of the five camera images does not correspond to the specified data in the computer system, then the can is removed from the can flow via a blow-off station.
Part 14: Palletizing
The palletizing unit assembles the cans in up to 23 layers to a package unit almost three metres high. The palletizing process starts by picking up an empty pallet. Layers of cans and interim layers are pushed on to the pallet until the required number of layers has been reached.
A cover frame made of steel forms the top layer. Plastic strips are wrapped around the package criss-crossing twice in order to make it stable for transport.
