Trunkline Box-Filling Conveyor Systems

An excellent way to increase productivity!
There are a number of ways to combine box-filling with a trunkline system. One method is to store and fill the boxes at the press and then move the filled boxes to the trunkline to be removed. Another method is to load the empty boxes onto the trunkline, divert them from the trunkline to the press, fill them at the press and then convey them back to the trunkline to be removed.

Trunkline diverters, divert empty boxes to the press.
This system, shown to the right, diverts empty boxes from a trunkline, fills them at the press and then moves the filled boxes back to the trunkline which transports them to a storage area.

How do Trunkline Automation Systems Work?
Empty boxes, coded with either a bar code or a color code, are loaded onto the trunkline.
1. & 2. A photo eye activates a bar code or color code reader. The reader signals if a suitable empty box is available
3. A pneumatic box pusher diverts the box off of the trunkline
4. The box is moved to the filling position. Parts are filled into the box, by weight, cycle count, part count etc.
5. A sweep arm moves the filled box to a power roller conveyor which moves it back to the trunkline
6. Pop-up sweep tabs push the box back onto the trunkline conveyor which takes it to shipping or storage.
