Product Lost: How to manage [PickMaster 3]

PickMaster
1

During the Pick&Place phase the picker doesn’t check by itself If the item in the gripper is present or not. To implemet this feature , until now I used a Trap routine connected to the Vacuum Signal. If I loose the Vacuum signal after a Pick it means that I loose the Item. Unfortunately this approach it doesn’t works always.

Please correct me If I’m wrong, but due to Picker’s Speed , the program pointer works in preprocessing if are not present Stop Point. In this way the robot can make a complete path without stopping point, and can reach easily the production throughput requested.

My question is: Is present, or can be possible, or better, why in the PickMaster we cannot implement this functionality, for istance in the PickWare. A sort of new instruction like

ActCheckSignal diVacOn,MyRoutine;

DeActCheckSignal diVacOn;

In this way, we run use this instruction (AckCheckSignal) before to start the pick&place; after the pick&Place we call the second instruction (DeActCheckSignal). It’ll be the robot at low level, that is in charge of control the signal and stop adn eventually modify the robot path.

Thank you.

Hello Davide,

Here is an example how you use the TriggCheckIO functionality to check if the pick operation was successful.

Hello Roger,

Thank you for your answer; I’ll try your idea.

I’ve already found a solution avoiding that the robot can go inside the Box (I’m use a trap but I define a state, and before to place I check this state), but I’ll try also your suggestion.

Thank, Davide.
