In any packaging system, each component should be carefully selected not just to do the job required, but to also integrate with the other components in the system. Think of the entire system as a series of units, with the maximum capacity and efficiency of the complete system based on the maximum capacity of the slowest functioning part.
Most packaging systems will include some form of case erector and sealing system. These case erectors will be rated for the number of cases they can process and seal per hour, with many offering speeds of more than ten cartons per minute or one every six seconds.
Basic Operation
The case erectors are located at the initiation of the boxing line. They will have compartments for storage of the folded cases or cartons as well as a system to push one carton into the system, open up the fold, seal the bottom of the box and propel the formed and sealed carton through to the conveyor where it will go on to be filled and sealed for palleting and shipping.
Considerations
There are several considerations with any type of case erectors under consideration. Choosing a reliable, durable brand name is always important as this ensures a dependable machine.
It is also essential to consider the sizes of cartons the case erector can handle. Most are flexible to handle standard carton sizes, but oversized boxes and cartons may not be suitable for all systems. Check to verify the system allows for warnings for low tape level on the unit as well as provides a visual check on the level of cartons or blanks in the holding compartments.
Floor space may also be a consideration when designing a new packaging system or in working a new case erector into an existing system. Most of the new units have a streamlined design to minimize the amount of space required for operation.
