The Sectional Flight Conveyor Screws Complete…
The Sectional Flight Conveyor Screws — CEMA Standard No. 300-002 — were added to the configurator, but we went WAY beyond that with the underlying model to align it more closely with an actual detailing methodology — specifically the one we found on the Martin Stock & MTO Screw Conveyor Components online catalog shown below…
Originally the model was structured to accept only standard size designations from the CEMA standard, but the standard excludes the MTO parts that are needed to create the majority of screw conveyors. Standard sizes are 10 and 12 feet (based on the screw diameter), and the shorter sized MTO parts such as the 5 foot section pictures above are needed to create something useable. So… that capability was added to the model, and the model now takes an Overall Length as a main input, then figures out the stock and MTO parts based on that.
Because the CEMA standard only specifies the thickness and bolt pattern for flange units, we also used the information from within the Martin catalog to create the Ball and Babbitt Bearing Flanges for the configurator as can be seen in the image to the right.
Martin Screw Conveyor components conform to CEMA standards where applicable, and these bearings are no exception. Using the drawings and tables in their catalog, we were able to model very good representations of these components, and will use them to show how the model can be connected to an ERP system when we get into the more advanced stages of the tutorial.
In the image below you can see the Sectional Flight Conveyor Screws as well as the Type 226 Hangers and Bearings that suspend them…
You can also see the configurator’s control form (click the image to enlarge) that has now been arranged to have tabs for the Screw, Trough, and the End Plates. There are also controls at the top and bottom which always remain visible. At the top is the Overall Length and a switch that turns of the visibility of the cover so you can see what’s going on inside, and at the bottom is the overall weight of the unit and a button to refresh that figure.
The Sectional Flight Conveyor Screws themselves are a combination of stock and MTO components, and I have added some fail-safes to the model to prevent the MTO section of screw from being too short. Also modeled are:
- 300-0017 Drive Shaft
- 300-0018 End Shaft
- 3009019 Coupling Shaft
…along with various bushings and pipe to hold all of these things together. Below you can see a Coupling Shaft where the Hanger Bearing rides…
I will try to get out a video of the model as it is seen above, but time constraints keep me from doing so until at least mid week. There is actually a lot more to show so stop back and check that out.
After the video post later this week, there will likely only be one more post that wraps up the modeling portion of this tutorial creation. All that is left is the trough saddles, nuts and bolts, and the trough cover clips. That final post will go over all of the model’s features and will delve into the plans for how the tutorial will be structured. Stay tuned… there is some interesting things on the horizon!
