This degree project has been carried out in cooperation with Gedevelop in Helsingborg.

Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.

Because of the density and viscosity changes in the glass, the weight information is

sometimes incorrect given. Glass industry is today addressing the problem by an operator

performing a manual weighing of a few bottles which, in turn, calibrates the camera system.

The project aimed to develop an automated system to control the weighing of glass bottles for

glass industries. This system must be so flexible that it can be easily mounted on plants with

different production equipment around the world.

The project includes design and construction of equipment that meets the requirements

formulated together with Gedevelop. Work has been done both in Halmstad and Helsingborg

and has included both calculations and review of the theory to understand the forces that

influence the design of different construction parts. A prototype was produced that meets the

operating requirements for the design and can be used in testing features. However, the design

does not meet the requirements to be set up at a production line because it does not pass the

temperature appearing in glass industry. This can easily be remedied by further modification

of the design in terms of protection of stainless steel.
