As CPGs continue to change their packaging lines to try and cut costs but stabilize runtime, there are a few things to consider when analyzing the cause of machine downtime and how to prevent it.
The below statistics were taken from the Fall 2021 issue of OEM Magazine:
Causes reports by respondents at CPG companies as the most common cause of packaging machine downtime: 26.3% general wear and tear, 21.1% operator error, & 22.1% product changeover.
General wear and tear is pretty self-explanatory. This would depend on how many hours and days per week a facility runs their packaging lines. If they are running 24/7, then the percentage of general replacement parts purchased will be higher than a plant that is only open 8 hours per day, 5 days a week. To lower downtime, each facility should stock at least 1 -3 replacements, at all times, of the following items: Heated Hoses, Glue Applicators, Modules, Nozzles, Tank filters, and In-Line filters. Another way to lower downtime is preventative maintenance. If CPGs were to prioritize preventative maintenance, then their packaging machinery would last longer and lead to less overall downtime. We recommend PM practices that include changing tank and gun filters, as well as maintaining an even level of heated glue in the glue reservoir of the tank. If done on the regular, general wear and tear percentages would go down.
Operator error is also another large concern for CPGs and the cause of most packaging line downtime. That is because Nordson® and other large corporate OEMs are making their melters more technologically advanced. Unfortunately, this increased technology does not come with increased training. While technology can create less human interaction, if the line operators are not trained on how to work the equipment, it can lead to more errors. Also, several of the new systems need to run on a network in order to work, so if there is any network downtime, that will now impact the packaging machinery and shut down the line. Universal Systems has maintained our simple to use systems and provides YouTube videos on how to work our machines, along with error codes and how to navigate the control board.
The final most common cause of packaging line downtime is product changeover. To lower overall costs, many CPGs use the same machines to package multiple types of items, which requires a changeover of parts. This downtime might be harder to avoid, however if the line operators are well versed in the machinery and understand the usage need of the machine in all areas, this can be lowered.
