When implementing an order picking system in a warehouse, management should consider using ergonomic workstations. Workers are more comfortable and more productive when their movements reduce strain on the arms, hands, legs, back and neck. Limiting repetition helps to reduce irritation of muscle groups and can improve the pick time for filling orders. Placement and accessibility of items for order picking or for parts picking and assembly is critical in order to achieve quickest pick times.
Ergonomic Placement
When workers are parts picking or order picking from a limited inventory, management can set up an ergonomic workstation to minimize reach and increase comfort. Gravity flow rack shelves should be set at an angle to allow inventory to propel forward against a stop bar. This is done using conveyor rollers on a tilted pick shelf. As the front carton is removed, the items that were behind it slide forward. The worker no longer has to reach further back through the empty space to access the next available item; it is already at the front for the shortest pick. It also prevents back and shoulder injuries by reducing the awkward lift and carry angles to retrieve products that were once on high shelves or too far back to reach safely.
Vision and Reach Angle
The tilt angle makes it easier to see what is on the shelf and improves the employee's ability to know when inventory is running low. Shelves at an ergonomic workstation can be set at the proper height to reduce neck strain from looking at shelving and arm strain from reaching. Bottom shelves can be raised to prevent back strain from reaching below or leg injuries from squatting to retrieve inventory. A footrest is placed at the bottom of the workstation to prevent knee strain.
Speed
Shelving with gravity conveyor rollers can increase pick times up to 50 percent as compared to static shelves. This improves the employee's performance and lowers the amount of time it takes to assemble parts or complete a customer's order.
Loading
Ergonomic workstations with tilted pick shelves can be loaded from the back to eliminate work stoppage while employees are waiting for inventory to be restocked from the front. This also makes it easier for the person loading, who has more flexibility on when they can restock, so long as they fill inventory requests before products run out completely.
Assembly
Workers performing parts assembly may improve their performance with an assembly shelf in front of the workstation. Set at the proper height, it is more ergonomically correct for the back and arms. This also reduces the need to shift items to a side work table, which also reduces the need to twist the back and legs when pivoting to move items from the pick shelf to the assembly table.
