[Sticky] SHOSHONE FALLS - Lessons Learned
This is a place to record considerations and concerns for future review. Employees and Installers feel free to comment below.
Verify the function and placement of the pneumatic lines, port connections and labels to the vacuum devices on the EOAT. As configured on Shoshone falls vacuum holder devices 1 and 3 are inline on one side of the tool and 2 and 4 should be inline on the opposite side. The system took some debugging to get proper vacuum and eject operations and the #3 and #4 vacuum grip devices were in swapped positions on the EOAT.
Bell Everman belt drive lubrication: Bell Everman recommends lubrication of the carriage drive belt system. If the lubrication of the belt is insufficient the sound quality of the belt drive system will change and take on a louder buzzing sound when the carriages are in motion. House of Design supplies a bottle of lubricant with each system.
Bell Everman commented that many customers of this drive type use a quality silicone spray lubricant with good results
The appropriate lubrication interval is still under evaluation.
Pick station rail deformation. Shoshone site experienced some rail deformation of the side rails on the assembly conveyor system due to board loss at the #1 pick station. The side rail was displaced closer to the table from repeated board jams on the departure side of the pick station between the center rail and the side rail on the table side. Suggestion sent to the ME team to consider structural improvements to the guide rail and supports to reduce the possibility of displacement or bending of the side rail system.
Infeed conveyor to press conveyor track height mismatch problem.
The conveyor height of the infeed and the press tracks needs to be well matched. If the conveyor is too low it can cause lumber to jam at transition to the press conveyor. Short pieces of lumber may rotate under the carrier #1 and eject from the conveyor, or tilt up.
Shoshone system sustained minor damage from the rotation of short pieces of truss lumber at this transition before the conveyor track heights were matched.
