The second gripper 60 may be individually connected to the drive mechanism. For the sake of compactness and energy saving, in the present embodiment, each second gripping element 60 is connected to two first carriages 31, respectively. The second gripper 60 can be configured to be pivotable as the first gripper 20, it being noted that, when the second gripper 60 is articulated to the first carriage 31, a restoring spring 42 is connected between the second gripper 60 and the first carriage 31 for restoring the second gripper 60 to the clamped state. As a specific embodiment, in this embodiment, the second gripper 60 is fixedly connected to the first slider 31. Because the reinforcing bar net piece 100 that the conveyer belt was transported is the state of bending and indulging muscle 1021 up, when the second snatched piece 60 snatched reinforcing bar net piece 100 from bottom to top, need not to dodge and bend and indulge muscle 1021, after the upset, the second snatches piece 60 under, first snatches piece 20 is last, when snatching the reinforcing bar net piece 100 of waiting to overturn because of the batch, is the reinforcing bar net piece 100 of same specification generally, when first snatching, can dodge the bending and indulging muscle 1021 of reinforcing bar net piece 100 through adjusting the position of reinforcing bar net piece clamping unit on crossbeam 70 for in the follow-up upset process, second snatches piece 60 top-down and also can avoid bending and indulge muscle 1021 when snatching reinforcing bar net piece 100.

After the reinforcing mesh 100 bends the longitudinal bars 102, the reinforcing mesh 100 is output by a conveying belt, the bending of the reinforcing mesh 100 is upward, and the reinforcing mesh 100 needs to oppositely set the bending longitudinal bars 1021 of the two reinforcing meshes 100 in the subsequent process, so that the reinforcing mesh 100 needs to be turned over by 180 degrees, and after the turning over, the bending longitudinal bars 1021 of the reinforcing mesh 100 faces downward. The second grabbing component is arranged, when the grabbed reinforcing steel bar net 100 needs to be overturned for 180 degrees and then put in, the reinforcing steel bar net 100 is firstly grabbed and put on the transition platform, then the second grabbing component is moved to the lower side of the transition platform, the position of the second grabbing component 60 is adjusted according to the specification of the reinforcing steel bar net 100, the second grabbing component 60 is inserted into the grid holes of the reinforcing steel bar net 100 from bottom to top, the first driving mechanism 50 drives the two second grabbing components 60 to expand or retract outwards to clamp the reinforcing steel bar net 100 and then overturn, the first grabbing component is arranged below, the second grabbing component is arranged above, after overturning, the first grabbing component is arranged above, the second grabbing component is arranged below, and therefore, during overturning relay, the reinforcing steel bar net 100 can be directly grabbed without overturning and restoring the reinforcing steel bar net clamping unit to the initial state. The second snatchs the subassembly top-down and inserts in the net hole of second reinforcing bar net piece 100, snatchs reinforcing bar net piece 100 and puts in on the transition platform, moves first snatch the subassembly to the below of transition platform, inserts in the net hole of reinforcing bar net piece 100 from bottom to top by first snatch the subassembly, presss from both sides reinforcing bar net piece 100, overturns again, after the upset, first snatch the subassembly under, second snatch the subassembly is last, first snatch the subassembly and second snatch the subassembly and can reduce the upset action of 180 at each upset relay in-process. When turning an equal amount of reinforcing mesh 100, the number of times of the whole turning of the reinforcing mesh clamping unit including the second grabbing component and not including the second grabbing component is shown in table 1:

table one:

from the first table, it can be obvious that when the reinforcing steel bar net 100 is turned over in batches, the production beat of the reinforcing steel bar net 100 can be greatly saved when the second grabbing component is arranged, the energy consumption is reduced, and the production efficiency of the reinforcing steel bar net 100 is improved.

Example 2

A reinforcing mesh production line comprising the reinforcing mesh clamping device described in embodiment 1.

According to the above description, the present patent application has the following advantages:

1. the first grabbing piece 20 can avoid bending longitudinal bars 1021 of the reinforcing steel bar mesh 100, and grabbing is reliable;

2. the screw rod 51, the nut transmission or the chain wheel and chain transmission are adopted, the grabbing action is without a pneumatic pipeline, static wiring is realized, a drag chain is not required to be arranged, the structure is simple, and the cost is low;

3. the overturning of the reinforcing mesh 100 is realized, the production beat is saved, the production efficiency is improved, and the energy consumption is reduced.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
