Machine malfunction due to Cantilever design

In summary, the speaker works for a machine design and manufacturing firm and is currently working on a project to solve a critical problem in an automatic part washing machine. The problem is caused by the orientation of the baskets in a cantilever state, which leads to bending and getting stuck in the sliding track. The speaker is looking for a solution to compensate or guide the fixture to avoid this deflection. They suggest a diagonal brace from the top of the fixture to the far end of the basket tray as a potential solution.

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?
 

1. What is a cantilever design and how does it relate to machine malfunction?

A cantilever design is a structural design in which one end of a beam or element is anchored while the other end is left unsupported. In machines, this design is often used for components that require a fixed point of support, such as levers or arms. However, if the cantilever design is not properly engineered, it can lead to imbalanced forces and cause the machine to malfunction.

2. What are the most common causes of machine malfunction due to cantilever design?

The most common causes of machine malfunction due to cantilever design include inadequate support, uneven weight distribution, and insufficient material strength. In some cases, design flaws or improper installation can also contribute to the malfunction.

3. How can machine malfunction due to cantilever design be prevented?

Proper engineering and design considerations are key to preventing machine malfunction due to cantilever design. This includes ensuring proper weight distribution, selecting appropriate materials, and conducting thorough testing and analysis before installation. Regular maintenance and inspections can also help identify potential issues and prevent malfunction.

4. Can a cantilever design be used in all types of machines?

While cantilever designs can be useful in certain machines, they are not suitable for all applications. The design must be carefully considered and engineered to ensure it can withstand the forces and stresses of the specific machine. In some cases, alternative designs may be more appropriate for optimal performance and safety.

5. Are there any benefits to using a cantilever design in machines?

Yes, there can be benefits to using a cantilever design in machines, such as providing a fixed point of support and reducing the need for additional components or supports. However, proper engineering and design considerations are necessary to ensure the benefits outweigh the risks of potential malfunction.
