Overview:
Mechanical Design of Factory Machinery modification. Update four Carbon paper reel wrapping machines to a 2 stage process in order to use an ecological wrapping material. (Single stage wrap with sheet foam no longer compliant with ecological regulations.)
Carbon copy paper reels (up to 2 tonnes each) wrapping machines got upgraded using pneumatics as the primary enabling technology for one factory site of an international paper company.
 
Carbon copy paper reels up to 2 tonnes each need a protective wrapping to prevent carbon copy imprints impregnating several outer layers of each roll. The foam sheet got replaced with a robust ‘crepe paper’ material. 
Work with:
Machine survey. 3D AutoCAD design. Pneumatics specs, symbols, & mechanism design. Logic diagrams for machine control. Organised and trained a colleague in 3D CAD methods for doing the detail drawings.
From top to bottom, the 3 additions comprising the design modification were: The Origa slider arms, the paper gillotine, and the vacuum plate.
Before the upgrade, the sheet foam can be seen near the top centre of the image being despensed from an arched guide plate.
After the upgrade, the origa slide arms and vacuum plate can be seen clearly.
Full 3D CAD data set. Right rear 3/4 of the machine modification.
Full 3D CAD data set. Right front 3/4 of the machine modification.
Full details of this role:
A/ Mechanical Design & Project Engineer for a small special purpose machine company using AutoCAD 11 in 3D and 2D environments.
B/ Responsible for mechanical design, innovation & detailing of a wrapping machine modification, along with surveying the original machines.
C/ 3D design methods done on Autocad, and the modification was operative within 2 hours of installation.
D/ Project completed in time and budget, proving the validity of 3D CAD methods.
E/ Responsible for one member of contract staff, including giving 3D CAD training.
F/ Presented a design review alone in Belgium with the Site Director and department heads for the site, which was part of a multinational paper company.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
