Pneumatic valve for cartesian robot

Click For Summary
SUMMARY

Jake Platt is developing a high-speed X/Y Cartesian robot equipped with a venturi vacuum for picking defective parts from a conveyor. He seeks a pneumatic valve capable of toggling the vacuum on and off, eliminating the need for a Z-axis, and requires a valve compatible with hoses the size of ping-pong balls. Current options found are limited to small diameters (10mm), prompting a request for recommendations on suitable high-speed pneumatic valves. An alternative suggestion was made to create small holes upstream to disrupt the vacuum instead of using a valve.

PREREQUISITES
  • Understanding of pneumatic systems and valves
  • Familiarity with Cartesian robot design principles
  • Knowledge of vacuum technology, specifically venturi systems
  • Experience with high-speed automation applications
NEXT STEPS
  • Research high-speed pneumatic valves suitable for large hose diameters
  • Explore alternative vacuum control methods, such as upstream venting
  • Investigate pneumatic valve suppliers specializing in custom solutions
  • Learn about the integration of pneumatic systems in robotic applications
USEFUL FOR

Engineers and developers involved in robotics, automation specialists, and anyone working on pneumatic systems for high-speed applications.

Hello,

I am trying to build a high-speed X/Y cartesian robot which vacuums up defected parts from a moving conveyor. The end effector of the robot has a venturi vacuum integrated. Because the vacuum is constant, I need a Z-axis to go up/down for the end effector to get the defects otherwise it sucks up everthing. This is very slow. I would rather keep the height constant of the end effector and instead toggle the vacuum on/off using a valve of some kind so I can eliminate the z axis. I can't seem to find what I'm looking for because valves I've found are for small diameters (10mm). I need a valve for hoses about the size of ping-pong balls. Can anyone suggest a source for a pneumatic valve in the size range and that can cycle in very high speeds?

Thank you,
Jake Platt

Interesting. Can you instead just open several small holes in the hose some distance upstream to spoil the vacuum at the end?
 
I misunderstood your point for 2 months. I was re-reading old posts and now i finally get your point. Clever! It never dawned on me to the leave the vacuum intact and just cancel the pressure.
