OEE 6 Big losses -The Small Stop
While it is SMALL, it can also be very BIG! 🤪 There we go again …
6 Big OEE losses #4-The Small Stop
Best way to understand Small stop is like traveling on a journey with the destinated place, along the way, you are estimating to reach the destination say in 1 hour, along the road
you bumps into a traffic jam, road blockages, accidents etc. These are the small stops.
In the production process, minor disruptions stop because of waiting for material to run, delay in getting the machine to run back after the disruption, equipment misallignment and jam up. These the are the common small stop that we were looking at.
some advance processes has built in function that detect what is the stop like. That again can rely on the Stack lighting indicator or within the controller like PLC to detect the error code due to the disruption. Why is these small stops is important? as you know when production is running 24 hours daily, all the small stops will be accumulated to then contributing to the big losses. although the name sound small, it is indeed a key contributing factor to the 6 big losses.
While some advance machine is able to detect the stop’s code, some legacy of machine may not be able to have this set of data. So, the small stop in the production are usually neglected and it end up to the big inefficiency in the process.
There are several ways of tracking stop stops. One of them to have a tracking talking to the controller or to sense it at the tower light in the event the machine is experiencing the small stop. But, that doesn’t end there, the best way is still to have a user interface to the operator to tell what has happened usually by disruption error code. All these codes with the accumulated time interval will then be used in the report or analysis to tackle the frequently occurs error code in order to improve or minimize the disruption.
There are several good solution for tracking this, one of them is the stack light tracker, where it records all the status of the lights indicator in a combination and the previoius state and current state of time taken are accumulated. That doesn’t end there, to have a good samll size Axiomtek graphical Operator Terminal with a Adisra Smart view HMI software tool is sufficient to gather all the data you want.
Lastly, in the Industrial IoT solution to Cloud like Insight view of Adisra, the data can be viewed real time on a dashboard with analytical report and to extend the power of AI analytic with Machine learning or rule based action based function, The optimization and efficiency can be brought to maximum.
