Super Air Nozzle, Stay Set Hose Assist Plastic Cup Separator

Whether due to static or not, plastic cups always seem to have a tendency to stick together.  You can never pull just one cup off of a stack without using both hands.  This is true not only for the consumer at a picnic, but also for the machines trying to separate the cups during the manufacturing process.

I spoke to one such manufacturer last week.  He has a machine that takes a stack of plastic cups, sends them through a corkscrew style conveyor and separator, which then directs each cup individually onto a rotating indexer for continuing on to the rest of the processing.

The corkscrew conveyor and indexer move at a very high rate of speed.  Sometimes the cups do not properly separate, and the conveyor misses one, thus leaving an empty spot on the indexer and a hole in the rest of the process.  This can create short quantities in the final packaging, among other immediate problems created by the jam-up at the corkscrew itself.

The customer was looking for a series of 4 nozzles equally spaced around the perimeter of the cup stack to provide a quick air blast to boost each cup off the stack and into the conveyor.  Because the corkscrew and indexer is in a rather tight area, a nozzle on the end of a straight, rigid compressed air pipe would not suffice.  Thus, I recommended that he use our Stay Set Hose along with the nozzles selected for the application.  That way, he could bend the hose whichever way was needed, and it would stay in place.

The nozzles I recommended were our model 1103 Mini Super Air Nozzles, as they would provide more than enough airflow and force, and would also be small enough to access the tight space.  Because mounting could end up needing to be adjusted until it was just right, permanent mounting was not desired.  Thus, I also recommended use of our magnetic bases in addition to the nozzles and Stay Set Hoses.  That way, the entire setup would be adjustable, yet would remain in place once set up. 

To make his ordering just that much easier, I was able to provide him with one model number to get all the component parts in the assembly we agreed on.  Model 1103-9456 consists of 2pc of the 1103 nozzle, 2pc of a 6″  Stay Set Hose, and one dual outlet magnetic base, with a manual control valve on each hose.  Model 1103-9462 consists of 2pc of the 1103 nozzle, 2pc of a 12″  Stay Set Hose, and one dual outlet magnetic base, with a manual control valve on each hose.  These two part numbers got him everything he needed for a simple installation that would provide an instant fix to his application problem.
