What Is a Collator for Packaging Automation?

A collating system is designed to collect, dispense, and arrange products into groups according to preset quantities and patterns, preparing them for the next stage of the packaging process. It normally includes a buffering conveyor, an accelerating conveyor, a collator, and a side pusher. 

The key component of the collator is a recirculating conveyor with primarily upright dividing plates, which receives products from an accelerating conveyor. Collator is called 集积器 in Chinese, Коллатор in Russian, Sammler in German, 콜레이터 in Korean and 集積機 in Japanese. 

When the leading dividers reach the dispensing station, the side pusher pushes the preset quantity of products onto a transfer station. Rows and layers are accumulated at the transfer station if each group contains more than one row or layer. For products such as small pouches, the collator is equipped with a partition cardboard placer that places a cardboard sheet between each layer to stabilize the stack during accumulation. The completed groups are then pushed onto the loading station once collated.

A collator is a crucial component for a multi-pack bundling or case packing system, as it considers your packing pattern and quantity. As a leading manufacturer of packaging machines in China, Calmus Machinery has developed and manufactured many collators for different products like stand-up pouches (doypacks), instant ramen noodle packets, sanitary napkins and diapers.

Products must be in the same orientation, in a single row with consistent spacing on the conveyor before entering the buffer conveyor of the collating system. If not, they need to be unscrambled by a dedicated machine upstream. For stand-up pouches, Calmus Machinery has the unscrambler which arranges pouches on conveyance into a single file, spaces out consecutive pouches, orients all pouch heads consistently with the help of a vision system, and turns them face-up when required.

A collator is a component of packaging automation, and Calmus Machinery can provide the complete multi-pack bundling and case packing system.
