Below are my illustrations of the type of work I have done at Bradmanlake. The work includes concept work through to issuing products to production to on site requirements.
These are typical examples, and I have been integral with the development of all the systems illustrated here.
Concept Illustration.
Here i have used a flow - wrapper and tagged onto it simple feedled to illustrations of how the product is handled. With this sort of system, often one picture is enough, however, some concepts require multiple images to illustrate their operation. Most of what i do is mathematical simulation, to prove a concept through, including timing diagrams, often limiting product handling to gravity. However, an image paints a thousand words and will often be the tool to aid selling, backed by the theory.
2010 - System Development a for USA biscuit manufacturer.
Here, within the design team, we have developed a card feeder and integrated it into a packaging / collation line. My input on this system is the infeed from the card feed, taking the card to the flow wrapper, also the collation mechanism, involving integration with three other designers for integration of units. Product is delivered to us at 70 rows per min, over two legs, With refeed, that equates to over 700 product per leg. The collator phases product into pitches, collates into pairs, then stacks pairs on top of each other. These four products are then placed onto the card which is fed from the side, then into the flow - wrapper. Linear speeds of 70 m/min, not exceeding gravity and continuous motion help to minimise product damage.
Typical System design.
This system date back a few years, however the concept is the same. Porbabiity calculations to determine the system, using basic building blocks to build a solution. Each area has been worked on over the years. The ADS (auto distribution system) has come from a 30 row/min to a rocket at 140 rows/min using servo technology and basic acceleration calculations, again limiting to gravity so the product stays where it should be. This system dates about 5 years.
Through the design teams input and continuous improvement we now have good modular design, increased throughput and a 'open' design, to enhance cleaning.
Typical Assembly Design.
Solid Edge provides fully parrametric modeling, through all levels in the assembly. A concept will often start as a sketch based on timings for the system. The sketch will then form the basis for the model, with parts parametricaly linked to the sketch. If for some reason, things change, the sketch is edited and the associated part will be updated. This is all great for concept work.
Thurther into a design it may be necassary to change things, without wanting to get tied up in the history and associativity a part may have. I now work in a similar manner to the latest Solid Edge releases, where the history of a part is ignored. Using the modify tools, you can now quickly change componenets with confidence. So there are two ways that i will design - fully assosiative, and the quick modify commands, ignoring history, or indeed a combination of both.
Solid Edge proved to be the most efficient tool to use for the products BradmanLake are making. SolidWorks and Autocad are also used, but to a lesser degree.
