Buffering

from Wikipedia, the free encyclopedia

The buffers is the bearings and Store similar process, (particularly for the goods workpieces ) in a buffer to be kept to a trouble-free operation to ensure. Buffering is a sub-process of the material flow . Buffering is used when the raw parts to be processed arrive at the machine or the workplace at random intervals or when the machining or processing itself is random. The raw parts in the buffer can also continue to work if the supply of raw parts is interrupted for a short time, for example in the event of faults at upstream workstations. In addition, it avoids a production in cycle as with cycle lines . The stock in buffers fluctuates around an average value. On the other hand, stocks in warehouses or storage facilities are either filled suddenly and continuously emptied or continuously filled and suddenly emptied.

Examples of buffering operations

The following examples are given in the specialist literature:

  • Queues in front of service centers, if the processes are random. These can be people at a supermarket checkout or at the post office, mostly workpieces that are in front of machines and wait for further processing or removal.
  • Goods buffer in front of workplaces for order picking .
  • Flow buffer in flow production . The goods lie on a conveyor belt. In front of a workstation they are dammed up by a lock. The worker takes a workpiece from the buffer, processes it and places it on the belt behind the barrier so that it is transported to the next workstation.
  • Circulating buffer: This is a belt that follows a closed course (circular, rectangular).
