Ideas and Options
First issue
Poor access tray and support in the way
Cannot see well
No particular place for tools (and to some extent, a problem is that tools are needed at all)
Storage location for replacement equipment is too far away. Equipment must be carried and lifted into position
Consequence is slow, with considerable strain on operator. Time is critical, since production is typically lost during the changeover period.
Before: Remove from cart, connect to fitting on bench |
Two people, lift. Hold in place to match rigid fitting, fasten with wrench.
Pull necessary components from cart, two or three test units per cart.
One person, no lifting
One test unit per cart, completely set up,
After: Move cart into place | Quick releases |
Quick releases, no tools needed
Quick disconnect hose coupling, quick release pin to secure cart to bench.
One person changeover in one-third the time that previously required two people, i.e. about 80% reduction in time.
Additional examples
Rapid dismantling and reassembly |
Meat processing equipment provides many good ideas for rapid changeovers. Because this equipment must be taken apart for rigorous cleaning several times per day, this industry has developed numerous techniques for doing so rapidly. These techniques can be applied in other settings.
