Operators do not have to walk around, totes are delivered to a workstation where order selectors pick items to order totes. This makes the picking process more accurate because the workstation shows the operator what to pick and where to put it. Goods to Man systems, which come in a variety of forms and configurations, boost pick rates so it makes the picking process also much faster.
An example of a Goods to Man principle by Inther
Before any order picking can be performed, the Goods to Man workstation has to be set in order picking mode by a supervisor. When order picking mode is active delivery totes will be diverted to the workstation’s lower level buffer. At the same time storage totes that contain the required SKU’s for the delivery totes are transferred from the shuttle storage to the workstation’s upper level buffer.
At some point both a delivery and storage tote are present at a put and pick position. Now the system will start a pick task that can be performed by the operator. The system will highlight the pick partition of the storage tote and asks the operator to scan a single article (parameter that can be disabled in later stage). After the article verification the system will show the required quantity to pick on the picklight and also activates the putlight at the put partition of the delivery tote. Additional support information regarding the task will be displayed on the monitor. The operator picks the requested quantity from the stock tote partition and puts it into the order tote partition. The operator confirms the task is finished by pressing the picklight confirm button.
After every pick task the system verifies if one or more storage or delivery totes are finished and makes sure they are removed before starting the next task.
