Engineering Datum #149
Project Objective:
Design a high speed sorting tipple for lumber which also will keep the tipple outfeed lumber controlled as a horizontal shingled layer (three destinations shown). Operating speed of up to120 boards per minute.
The resulting design included a two stage air cylinder linkage that caused the tipple to decelerate to a cushioned stop in both the up and down cycle. This removed the shock load caused when the cylinder hits the end of its stroke. Addition features include polyurethane round tipple belts for high friction control and geometrical slide shapes that keep the boards under control.
The design works well on conveyor applications routing lumber to another out of line device or conveyor. In an engineered “Z” or “U” flow these tipples and their drop configurations eliminate almost all of the downtime caused by “pick up sticks” situations in other similar systems.
