Automated handling system promotes fast operation of handling and moving of goods. It minimises interation between the goods and human. In cases of dealing with hazardous prducts, automated handling system will be useful as it reduces empolyee risk and safety. However, introducing this kind of handling system need huge capital investments and space for further develpoment.

1) ASRS ( Automated storage and retrival systems)

ASRS refers to a variety of computer-cotrolled methods for automatically placing and retriving loads from specific storage locations.




























How ASRS works?

Step 1: Bin call by operator using barcode, keyboard or process .








Step 2: Simultaneous traverse and lifting movements to position table in front of selected bin,













Step3: Load pick-up and contour check before transfer.

















Step 4: Simultaneous traverse and lifting movements to bring bin to operator.

Step 5: Part pick-up.

Step 6: Bin return to sight-hole at operator request

Step 7 : Bin deposit. Table back-off. Stand by for new orders.

Step 8: Dynamic location management.


In a more complex automated operations, ASRS software consists of:

a) Monitoring and controlling the complex transportation system moving loads into and out of ASRS equipment, including operations of conveyor systems transfers, pallet, elevators etc and also rejecting those loads which are not able fit into the storages.

b) Visibly identifying loads for quantity, part number and manufacturer and updating the inventory plus.

c) Assigning specific address for each individual load. Locating the goods to specific aisles according to their specifications.

d) It can retrive loads based on either FIFO ( First-In-First-Out) or FILO (First-In-Last-out).

Advantages of ASRS:

-Bringing material to the operator and reducing cycle time by removing wait, movement, and search time.

-Reduces work-in-progress inventory. Better inventory accuracy and better responsiveness in reduction or elimination of “buffer stock” in the overall inventory model. This has the net effect of inventory reduction.

-Dramatically increases operator productivity. The “Part to Picker” model of order fulfillment is 3 to 5 times more productive that having the picker travel to the part to complete the fulfillment .

-Provides real-time inventory control with instant reports. Almost 100% accuracy and real time information about the inventory on hand, achievable commitments can be made to your customer – as opposed to “best efforts promises”.

-Improves product quality and productivity. Real time information, faster response to a need, physical protection, and traceability of material access all contribute to a better process where time can be spent on improving the quality of the process instead of on expediting material to a point of use.



Order Selection Systems:

It is a method of operating the system for retrieving multiple types of items stored in pre-selected storage locations and delivering retrieved items in an orderly sequence to the packing stations in accordance with specific requirements of different orders.



The order selection system consists:
A dispenser
A conveyor

















A dispensing control system;

A sorter;








Stacking devices;
