Parts Diverting - Reverse Control Separation

If an injection molding machine is capable of sending a 'bad shot' signal, bad parts can usually be removed by using either a parts diverter or a reverse control on the under press conveyor.

Reverse Conveyor Control
When a conveyor with reverse control is used to remove parts, a signal from the molding machine is used to signal the under press conveyor to reverse until the parts are removed. Once the parts have exited the conveyor, the conveyor returns to it's original direction.
Pneumatic Parts Diverter
When a diverter is use to remove bad parts, a signal from the molding machine activates a time sequence that is used to control the diverter. This pneumatic chute diverter is fitted onto the end of a conveyor. While this particular unit was developed to remove bad parts, it could also be used to periodically remove parts for inspection or as a two station box-filling system.

How does it work? There are two chutes at the end of the conveyor, an upper chute and a lower chute. Pneumatic cylinders are used to raise or lower the upper chute If the shot is good, the upper chute remains down and the good parts exit through it into a container If the shot is bad, the molding machine sends a signal to the diverter to raise the upper chute. This creates an opening which allows the bad parts to fall into the lower chute, and into another container After a predetermined period of time, the top chute returns to its original position
