Robotic Static Table Systems are:
DESCRIPTION The Static table cell is a low cost alternative to a flexible type system. It is used for smaller parts with very long production runs, due to the difficulty in achieving quick job changes.
An inherent problem with this type of cell layout is achieving adequate guarding to the required legislation. To enable the operator into the work envelope of the robot, whilst it is working in close proximity needs careful design, and to be truly effective not only movable solid screens but also light guards are needed. These safety equipment costs can negate the price difference to a much more usable system.
If you can touch the robot arm whilst it is working, it is probably not guarded sufficiently.
