Hi all,
We have a robot that is placing pumps into shampoo bottles. (HP5, NXC100)
Around the bottle neck, we have a guiding funnel that is opened and closed using a set of pneumatic grippers.
So the sequence goes..
- Funnel is closed around bottle neck
- Robot lowers pump into pump straw into funnel until it enters bottle neck
- Funnel opens up, sending a signal from a sensor to the robot
- Robot lowers the rest of the pump onto the bottle neck when it receives the signal.
Now the problem.
There have been instances of the robot placing the pump whilst the funnel has been closed, breaking the funnel and gripper.
We are considering a range of solutions.
The one I am enquiring about here is:
- How do I latch the movement of the robot to the input signal?
I would like it to move when the signal is on.. stop if it loses the signal.. continue when the signal resumes until it reaches its programmed target position.
Any takers?
Thanks
