Friends,
I have a project that may be coming up shortly. The project is based on a dispensing line, the attached pdf. file has a quick sketch of what the equipment will look like. The top solid belt conveyor will carry items for tray loading. Second bottom conveyor will carry plastic trays about 1’ wide 2’ long. The bottom conveyor ( tray feed conveyor) is a chain driven conveyor, meaning instead of a solid belt it has two chains on each side of the conveyor running the whole length of the conveyor.
Once the tray is in a loading position detected by photo switch ( not shown in a sketch and would be at the 1st position) tray would stop and wait for the 1st item to be loaded. Once item has passed the photo eye ( shown on sketch top conveyor) the tray brake pad will release and once the 2nd loading position is detected the brake pads will engage waiting for another item to drop.
The issue I’m having here is that the trays are completely flat on both sides thus eliminating any idea to detect any of the seven positions on the tray. Also the tray feed conveyor is running continually.
I was thinking to place seven photo switches to catch the trays side each switch for every position. Please I’m open to any suggestions. Most likely a micrologix 1500 will be used.
