about a potentially large increase in software development for very complex systems.
There is much hope that vision systems, sensors, microcosm-pressors, and advanced guidance technologies will be fully integrated with other components into CIM networks. In addition, the increased use of CAD and CAE will have a dramatic effect on tin design of material handling systems. An important component to this is the simulation system which can easily and accurately model material handling flow.
By combining advanced computer technology with sophisticated machine controls it will be possible to create automated storage and retrieval systems capable of operating in real-time in speeds never before thought possible. Besides, the traditional functions of storage and retrieval have been expanded to include information tracking, monitoring, and control of both inventories and work-in-process.
This is precisely what today's user of material systems looking for. The user today is looking for automated material handling systems. He wants to ensure that a part can be found when it is needed.
The major future developments are expected to be in the design of unified, flexible systems that fully exploit the capabilities of application software.
For example, the introduction of micro-loaders will extend mini-load AS/RS configurations into progressive assembly applications. In these systems, computer-driven robotics will carry the work to successive work stations where bar coding will determine. when and where the work will go next.
A computer-driven AS/RS of the immediate future will also permit surge accumulation within the system on the factory floor at the point of use. The system will pick, put, or store under computer control, and work status information will be available on demand.
It is quite possible to predict that AS/RS can become integral to flexible manufacturing cells. Interacting with the manufacturing machines, they will download on demand and remove finished work for transport to the next operation.
USE OF AGVs GROWS WITH FMS
As flexible manufacturing systems (FMS) grow in size and complexity, the role of material handling in such systems gain, importance. Increasing demands are placed on the functional capabilities, performance and flexibility of the materials handling systems.
It is possible to say that the emergence of automated guide |
vehicles (AGVs) may solve these new, handling demands, being used as a means of flexible in-plant transport.
It should be stressed that recent trend lies in the historical development of FMS. The initial search for flexibility in manufacturing was on the machine tools. Computerised numerical control (CNC), automatic pallet changing and other technical advances produced the flexible machining centre, capable of unattended machining of a variety of parts with a high rate of machine utilization. The next major step was to link several such machining centres by means of an automated transport system. Such an installation, under the control of a central computer system, is an FMS.
Earlier FMSs have made extensive use of static conveyors and rail guided transfer carts for the transport of workpieces. Whilst these means of transport were adequate for small systems, the full scale FMSs being developed and built, today place greater demands on the functional capabilities of the transport system-demands which can only properly be met by AGVs.
Thus, in a typical FMS raw workpieces are received on wooden pallets and transported to the set-up area, either directly or via intermediate storage. In the set-up area each workpiece is loaded onto a machine pallet, and clamped into position ready for the next machining step. After being taken to the machining area, it goes to a deburnng machine, washing and further to the inspection area. Each machining centre is equipped with a tool magazine containing the tools required for a large number of cutting operations.
Occasionally new tools are required either for new machining programs or to replace worn or broken tools. In this case, the new tools arc selected from a central tool store and loaded into a dispenser which is transported to the machining centre where used tools in the magazine are exchanged with new tools in the dispenser. This material flow described refers to FMSs based on modern CNC machining centres. An FMS may, of course, also incorporate conventional, manually operated machine tools to which workpieces are transported directly on wooden pallets and set up at the machine.
AGVs are designed for transporting a variety of loads at irregular intervals and with varying frequencies to and from a fairly large number of locations. But AGVs may not be suitable for all FMS applications and their applicability is determined mainly by the size and weight of workpieces and their machining cycle times. Small workpieces with machining times of only a few minutes require a more or less continuous form of transport for which conveyors are more suitable than AGVs. Often, however, such small workpieces are set up and machined in groups which are then suitable for transport by AGV. |
