Fig. 2 is the part producing process flow diagram of a concrete case, and is as shown in Figure 2, and 104SR is bucket-wheel stacker reclaimer wherein, and 102BC is the feed belt that passes bucket-wheel stacker reclaimer, and 101BC is the upper reaches belt of 102BC, and 103BC is the downstream belt of 102BC belt.
Bucket-wheel stacker reclaimer is because of itself being (to comprise cart by a lot of skinny devices; Arm belt; Bucket wheel etc.) device body of forming in order bucket-wheel stacker reclaimer to be participated in the chain control of stock yard flow process, is 3 equipment with bucket-wheel stacker reclaimer according to the different decomposition of working method:
1) has the process end equipment of windrow function;
2) has the process starting point equipment of getting the material function;
3) has the intermediate equipment of straight-through punishment in advance function.
For example, stacker-reclaimer 104SR among Fig. 2 can be broken down into the equipment 104SR1 with windrow function, has equipment 104SR2 that gets the material function and the equipment 104SR3 with straight-through function.
The condition that equipment is controlled automatically in the chain control of flow process is the state through its upstream and downstream equipment, and the upstream and downstream of equipment accurately and reliably in therefore necessary definite each flow process.Be divided into 3 equipment of separating into by the above bucket-wheel stacker reclaimer by working method; For the upstream and downstream of guaranteeing to decompose back equipment correct; We also are correspondingly processed the belt 102BC that passes bucket-wheel stacker reclaimer 104SR; So just avoided 102BC be the upper reaches of stacker-reclaimer also be the fuzzy logic in its downstream, guaranteed the correct reliable of chain program.The upper reaches 102BC1 of 104SR1 when the belt 102BC among Fig. 2 is broken down into windrow; The downstream 102BC2 of 104SR2 when getting material; The upper reaches 102BC3 of 104SR3 when straight-through.The downstream of 104SR3 as can be seen from Figure 2 are 103BC when straight-through.
