Singulating Bunched Product, Then Pulling a Gap

We recently manufactured an in-motion checkweigher for a company with a problem that is becoming more common in food plants.  The customer has an automated process in which several pieces of its products emerge close together from a machine each time it cycles.  In this case, it was an injection machine that makes meat products more moist and tender.  Many other automated processes, such as bag and pouch filling systems, present a similar situation requiring products to be singulated before they can be automatically checkweighed.

Our customized solution to this customer’s need to get product singulated and separated so that only one item at a time was on the live scale section of the in-motion checkweigher was a three-step process.

First, we positioned an incline conveyor at a 90 degree angle to the injection machine.  That step successfully put the product in single file as it travelled away from the injection area. We also attached product guides on the incline conveyor just in case a little extra help is ever needed keeping product in a nearly straight line.

The second step in our solution was to position the incline conveyor slightly above the in-motion checkweigher system.  By requiring the product to drop a short distance onto the checkweigher system, we made sure that each product was positively presented to the checkweigher system.  That drop also started the process of pulling a gap between each steak.

Singulating Conveyor contains individual belts which permit individual product lines to advance while other lines are held back. Once a space opens up, the stopped belts will advance the product. The merging conveyor ensures all products are directed to the center of the belt.

Finally, we set the speed of the belts on the in-motion checkweigher system much higher than the belt speed of the incline conveyor.  That allowed us to complete the gap pulling process, ensuring that only one product at a time is on the live conveyor scale section.
