4.Parts Presentation:

Naturally, the workcell will require additional components during the average work shift. In a lean workcell, traditional techniques of resupplying workstations

are not useful. With the minimum number of interruptions, each worker can go about his job. Each part should also be delivered from outside the work cell to each workstation. The use of gravity feed conveyers or bins suits the lean workcell's streamlined nature. Parts bins should be filled from at the back (outside the work area of the work cell) so that production can be continued without interruption by the worker. Gravity transports the components to the area of reach of the worker. Bins can be reconfigurable as well. The containers using a key stud in the picture to secure them in place [30]. When reconfiguring the workspace, bins are conveniently stackable and provide the ultimate in flexibility.

While bins are suitable for small parts, larger parts are needed for many assemblies. In bins or boxes, these can be shipped. Again, without entering the workspace, the components should be sent to the workcell. This function is served well by gravity feed conveyors. An additional gravity feed conveyor can be placed in the reverse direction if scrap, or containers must be removed from the cell. Lift assist devices are recommended in instances where pieces are very large. With mechanical, pneumatic, or hydraulic control, heavy parts or boxes of parts can be loaded onto a case lifter and lifted to the correct working height.
