16) left end table top is fallen: left end lifting platform motor M1 reverse starting, causes left end lifting platform (17) face along descent direction Y' falls next lifting travel in place；At this point, left end lifting platform low level travel switch XK1, issues a left end lifting platform (17) Switching value output signal in place is fallen, i.e. left end lifting platform motor M1 stops working；

17) lower layer's left upper end pushes:

A) piston rod stretches out: left end push cylinder Q3 piston rod stretches out, and pawls (24a) in left end cylinder driving delivery device (24) It turns left along lower layer direction of advance Z and stretches out a stepping Overstroke, i.e., lower end rack will be located at by (24a) impetus of pawling Flat shape track (40), lower end rack v-shaped track (41) left end 1 consignment trolley (23) push to left end lifting platform (17) Left end platform v-shaped track (36), left end platform are on flat shape track (37)；At this point, magnetic sensible switch CG5 on the left of the cylinder of lower-left end, hair Out one pawl (24a) pneumatically push signal, i.e. right end push cylinder Q3 piston rod have stretched out original position in place；Then, left end Trolley optoelectronic switch GD1 is detected, a left end detection trolley light beam α 1 is issued and blocks signal；

B) piston rod bounces back: left end push cylinder Q3 piston rod retraction, pawls (24a) in left end cylinder driving delivery device (24) Along lower layer direction of retreat Z' turn right retraction one stepping Overstroke；At this point, magnetic sensible switch CG6 on the right side of the cylinder of lower-left end, issues One (24a) pneumatic retraction signal in place of pawling, i.e. left end push cylinder Q3 piston rod have bounced back original position；

18) row after the stepping of lower end: lower end step device motor M4 reverse starting, lower end step device (35) are detached from home state, Wherein lower end stepping collision block (35a), lower end device stepping shift fork (35b) together along lower layer direction of retreat Z' turn right stepping after row one A stepping Overstroke；At this point, travel switch XK8 on the right side of the stepping of lower end, issues the switching value of row in place after a stepping of turning right Output signal, i.e. lower end stepping collision block (35a) have depressed travel switch XK8 on the right side of the stepping of lower end, and lower end step device motor M4 stops working；

19) lower end stepping moves ahead: the starting of lower end step device motor M4 forward direction, stepping collision block in lower end in lower end step device (35) (35a), lower end device stepping shift fork (35b) together along lower layer direction of advance Z turn left stepping move ahead a stepping Overstroke；This When, lower end stepping left side travel switch XK7 issues the switching value output signal that a stepping of turning left moves ahead in place, i.e. lower end walks Travel switch XK7 on the left of the stepping of lower end is depressed into collision block (35a), and lower end step device motor M4 stops working；

20) left end limit is risen: left end goes up and down limiting cylinder Q1 piston rod and stretches out, in left end Pneumatic elevation limit assembly (18) Left end axle sleeve (18a) rises until in place, covering on vehicle band limit pin shaft (23a)；At this point, left end cylinder high position magnetic sensible switch CG2 issues the switching value output signal that a left end axle sleeve (18a) has been raised limit, i.e. left end lifting limiting cylinder Q1 is living Stopper rod stretches out in place；

21) left end table top rises: left end lifting platform motor M1 starts to start, and causes lifting platform (17) table top in left end together with its pop-up Fortune trolley (23) starts to rise a lifting travel in place along ascent direction Y together；At this point, left end lifting platform high position travel switch XK2 issues a left end lifting platform (17) and has risen switching value output signal in place, i.e. left end lifting platform motor M1 stops work Make；

22) terminate this conveying: this after circulation terminates, can be according to need to make two kinds of selections:

A) continue to convey: if needing to continue, be back to " step 3) ", and repeat subsequent step, then can enter subsequent work and recycle；

B) terminate conveying: if needing to terminate, being back to " step 1) ", be threaded to system start stop switch SA1 " to stop " position, that is, close electricity Source terminates transportation work.

2. a kind of automatically controlled process of step-by-step movement bilayer circulation conveying mechanism according to claim 1, it is characterised in that: above-mentioned Automatically controlled signal involved in automatically controlled each step of process, is sequentially sent to PLC technology for its signal by respective automatically controlled circuit Its corresponding control is completed in device (3), the instruction of execution logical operation and sequential control etc. in due course, sequentially processing in real time.
