The following is a description of the utility model and its predecessors in connection with certain specific embodiments:
the efficiency of the utility model is as follows: the control unit controls the translation mechanism 16 to drive the walking frame 20 to wait below the upper plate (zero state), and after the workpiece on the lower conveying roller conveyed by the previous path is centered, the lifting mechanism 18 is lifted, so that the overturning arm 16 is lifted from a gap between the conveying rollers, and the sucking disc 18 is contacted with the upper plate; the control unit controls the negative pressure generating device to generate negative pressure so as to adsorb the upper plate (timing 1 s); after the lifting mechanism 18 is lifted 20 cm away from the roller conveying surface, the translation mechanism 16 is retracted to drive the upper plate to leave the conveying platform, and the walking distance is about 1.5 meters (3 seconds in time); lifting mechanism 18 is raised to a designated position, translation mechanism 16 is raised (timing 2S, position adjustable), translation mechanism 16 is moved about 0.4 meters, and the upper plate is moved directly above the lower plate (timing 2S); the turnover mechanism 14 turns over, the negative pressure generating device generates positive pressure, the upper plate is loosened (timing 2 s), the plywood is completed, and the mechanism is reset. The single-pass meter 10s, reset 10s and one cycle count time about 20 seconds, and when the upper plate is moved out from the lower conveying roller, the front conveying workpiece can be directly conveyed to the lower conveying platform without waiting, and the upper conveying platform and the front workpiece can be conveyed as is without waiting at all when the upper plate is in the plywood. Wherein, the lower plate can synchronously complete the centering operation, so the time is ignored. Meanwhile, after the upper plate leaves the conveying platform, the next upper plate can be conveyed forwards, so that the waiting time of the upper plate is saved; centering of the lower plate is accomplished synchronously in the above process, and thus, timing is not required.
Efficiency of the previous case: the time of the above steps is about: the upper plate is adsorbed and lifted (timing 1 s); the lower plate is transported to the platform and centered (timing 5 s); the turnover mechanism 14 turns over, the lifting mechanism 18 descends, the negative pressure generating device generates positive pressure, the upper plate is loosened, and the plywood is completed (timing 7 s); after the workpiece after waiting for the plywood leaves the conveying platform, the turnover mechanism descends below the conveying platform surface, the workpiece before conveying can be conveyed to the turnover plywood platform after the turnover mechanism sinks below the conveying surface (consuming 2 s), the waiting time is 30 seconds, and the accumulated time is about 45 seconds.
From this, it can be seen that: in the utility model, the operation of a single plate-turning plate takes 20 seconds, while the original scheme takes 45 seconds and 25 seconds.
In the utility model, when the plywood is finished, the next upper board is already in place, and the next lower board can be in place in the process of repeatedly taking the upper board, namely, no waiting time exists.
In the prior art, the next upper plate needs to be transported after the previous upper plate is completed, i.e. after waiting 15 seconds (timing 5 s), and the accumulated operation time for one cycle is 45 seconds.
That is, in the case of continuous operation, the previous one-plywood operation takes 45 seconds as a whole, whereas the present utility model requires only 20 seconds, thereby greatly improving the production efficiency.
The flow control according to the present utility model is well known in the art and is not innovative and is not shown in detail.
The flow control according to the present utility model is well known in the art and is not innovative and is not shown in detail.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
