Machine malfunction due to Cantilever design

Click For Summary
SUMMARY

The discussion centers on a critical design flaw in an automatic part washing machine caused by a cantilever design. The machine's basket experiences a deflection of 20-25mm, leading to operational issues as the basket gets stuck on the sliding track. The user seeks solutions to mitigate this deflection, specifically considering the implementation of a diagonal brace from the fixture to the far end of the basket tray as a potential fix. The conversation highlights the need for structural reinforcement in cantilevered designs to enhance functionality.

Hello all!

I work for a machine design & manufacturing firm. We also do machine repairs & refurbishing work.

We currently have taken up a project where-in an we have to solve a critical problem in an automatic part washing machine. The machine is a multi-stage concept, wherein the parts are loaded in a basket & are transferred from one stage to another by a pusher mechanism.

These baskets travel and are located in fixtures, but the orientation is in a cantilever state due to which the far end of the basket bends due to the weight. The deflection is almost 20-25mm due to which the basket, when it begins to slide ahead, hits the sliding track and gets stuck.

Please view attached sketches for knowing the general arrangement of the system.

My requirement is to somehow compensate or guide the fixture so as to avoid the deflection due to the cantilever design.

Hit me up for any more queries! Any help would be appreciated!

Is it safe to say the obvious is disallowed? A diagonal brace from top of fixture to far end of basket tray?
