Specific embodiment
Feature and principle of the invention are described in detail below in conjunction with attached drawing, illustrated embodiment is only used for explaining this hair
It is bright, not limited the scope of protection of the present invention with this.
Idler wheel pipeline divides left and right ends self-movement mode, and the left and right sides of idler wheel is mutually independent control, mutually
It does not interfere, as shown in Figure 3.
When most starting, being simultaneously emitted by left and right sides of idler wheel allows to receive glass signal, and glass infeed end judges according to program
Glass successively is placed in idler wheel two sides, after side receives glass material, allows to receive glass signal-off, glass infeed end
Glass can be placed into another side wheel.
After glass, which is moved to crawl, waits position, there is positioning system to position glass on idler wheel, after the completion of positioning, hair
Respective side allows to grab signal out, and glass flowing end can grab the glass on corresponding idler wheel.
Glass infeed end and glass flowing end be all glass is picked and placed from carrier, therefore carrier replacement during, glass
The case where glass infeed end will appear the case where pause feed, and glass flowing end also will appear pause feeding, therefore be fed and taking
When the case where material suspends, the cache mechanism on idler wheel is needed to cache glass, improves equipment operating efficiency.
Cache mechanism has two positions position A and position B on idler wheel.When in position A, glass can pass through slow
Mechanism is deposited, cache mechanism position when which is glass in normal conveying and release cache mechanism.At this point, cache mechanism
The glass barrier block gone up and down in cache shelf is concordant with idler wheel pipeline plane, as shown in Figure 4.When in position B, glass is buffered
The stopper of mechanism is blocked in cache mechanism, which is the position of cache mechanism when caching glass.At this point, glass barrier block
Position be higher than idler wheel pipeline plane, glass support item is concordant with idler wheel pipeline, as shown in Figure 5.Pass through a following Duan Cheng
Sequence may determine that cache mechanism is in position A or position B.
Judgement on the inside of screen cache :=(REAL_TO_LINT (initial position on the inside of screen cache inner side-caching))
MOD (REAL_TO_LINT (the high inside of cache layer))；
Judgement=0THEN on the inside of IF screen cache
Inside, which is buffered in, passes through position :=TRUE；
It is buffered on the inside of ELSE and passes through position :=FALSE；
END_IF。
As shown in Figure 1, when the case where glass infeed end normal feed and glass flowing end normal feeding, at cache mechanism
In the position A of respective layer, glass can be transported to crawl and wait position, located system determines glass normal through cache mechanism
Behind position, glass flowing end is waited to take glass away.
When the case where glass flowing end suspends when glass infeed end normal feed, judge that crawl waits whether position has glass
Glass waits glass to enter crawl and waits if if crawl waits position not have glass, cache mechanism is in the position A of respective layer
Position.If if crawl waits position to have glass, cache mechanism is in the position B of respective layer, glass is prevented to pass through cache mechanism, behind
The glass come is blocked after entering cache bit, and then cache mechanism rises one layer, and next sheet glass is waited to enter cache mechanism.
When cache mechanism rises, it can judge cache mechanism is currently at how many layer by following one section of program, be set when reaching
After given layer is high, cache mechanism does not continue to rise.
IF InitStc=TRUE THEN
StcANUM:=0；
Clear(StcA)；
StcASize:=SizeOfAry (StcA)；
END_IF；
IF StcAPushStat THEN
StackPush(StcANum,StcA[0],StcASize,StcANum)；
END_IF。
As shown in Fig. 2, glass flowing end situation is judged, if glass flowing end is also temporary when glass infeed end is suspended and is fed
Stop feeding, then the position for maintaining cache mechanism current is constant.If when the normal feeding of glass flowing end, continuing to judge glass crawl etc.
Whether there is glass to position, if there is glass, the position for maintaining cache mechanism current is constant, if without glass, cache mechanism decline
One layer and it is in position A, is that the glass of respective layer in cache mechanism is fallen on mixed wheel, and is transported to crawl waiting by idler wheel
Position.After glass waits position to crawl, being positioned by positioning mechanism for rolling wheel and being issued allows to grab signal accordingly.When crawl etc.
After the glass of position is taken away by glass flowing end, cache mechanism continues one layer of decline, and glass is transported to crawl and waits position, is waited
Glass is taken away by glass flowing end.
When cache mechanism declines, it can judge cache mechanism is currently at how many layer by following one section of program, when reaching layer
It counts to after 0, i.e., cache mechanism reaches the bottom, and caching does not continue to decline, and the glass in cache mechanism is released completely at this time
It discharges into.
IF StcALIFOStat THEN
StackLIFO(StcA[0],StcAOutVal,StcASize,StcANum)；
END_IF。
