Specifically, in the initial state, the telescopic end of the auxiliary cylinder is in the state of minimum telescopic distance, the air pressure in the auxiliary cylinder keeps consistent with the outside, the air pressure in the auxiliary cylinder can change along with the telescopic distance of the telescopic end along with the descending of the mesh clamping device 4, so that tension is generated for the mesh clamping device 4, the tension can also change along with the change of the air pressure along with the difference of the descending height of the mesh clamping device 4, the reset effect is provided for the ascending of the mesh clamping device 4, and the work load of the vertical driving device 5 is reduced.
In addition, in order to prevent the vehicle body 2 from being detached from the horizontal guide rail 32 and the vertical guide rail 52, the present embodiment is provided with a stopper 6 on the frame 1 at a limit position where the vehicle body 2 moves in the horizontal direction. As shown in fig. 1 and 3, the limiting block 6 has an L-shaped structure, i.e. the upper end of the limiting block 6 extends horizontally. During operation, can set up and be net piece clamp position and net piece position of placing respectively at the both ends of horizontal guide rail 32, touch stopper 6 when automobile body 2 reaches this position promptly, can prevent on the one hand that automobile body 2 from breaking away from horizontal guide rail 32, on the other hand can also play the locate function. And when the two positions are located, the section extending from the upper end of the limiting block 6 is located above the horizontal driving shaft 312 and the vertical driving shaft 512 connected with the vehicle body 2, so that the vehicle body 2 can be blocked, and the vehicle body 2 is prevented from being separated from the upper part of the horizontal guide rail 32.
To sum up, according to the mesh placement machine of the embodiment, the meshes which are horizontally stacked together can be automatically clamped, turned over and adjusted, the distance between the two meshes is adjusted, and then the meshes are sent into the fixing device to be produced for the mesh cage, so that the production efficiency of the mesh cage is effectively improved.
Example 2
A mesh placing method adopts the mesh placing machine of the embodiment 1 to perform mesh placing work, and the specific process is as follows.
1. Before starting, the horizontal driving device 3 drives the vehicle body 2 to move above two adjacent meshes, the meshes are horizontally stacked, then, as shown in fig. 10, the vertical driving device 5 works to drive the mesh clamping device 4 to descend to the mesh stacking position, and the overturning clamping hands 422 of the two overturning clamps 42 clamp the meshes respectively.
2. As shown in fig. 11, after the vertical driving device 5 drives the mesh clamping device 4 to rise, the turning mechanism drives the turning clamp 42 to rotate until the mesh is in a vertical state, and in this embodiment, the mesh is turned inward by 90 °. The cylinder I424 is then retracted to bring the inverting clamp 42 to the designated position, in this embodiment two web sheets are brought under the lifting grips 433 on either side of the lifting clamp 431. Then, as shown in fig. 12, the lifting clamp 43 works, lifting clamps 433 at two sides of the lifting clamp seat 431 clamp one mesh respectively, the turning clamp 42 releases the mesh, then the driving cylinder I424 works to return the turning clamp 42 to the initial position, and the turning mechanism controls the turning clamp 42 to turn 90 ° to return to the initial state, so as to complete the transfer of two meshes from the clamp of the turning clamp 42 to the clamp of the lifting clamp 43. It should be noted that, the distance between the two mesh sheets can be controlled by controlling the distance between the lifting grip 433 at two sides of the lifting grip 431, so as to play a role in adjusting the distance between the mesh sheets. If the lifting handles 433 on two sides of the lifting clamp 431 are fixed on two sides of the lifting clamp 431, the distance between two net sheets can be adjusted only by adjusting the width of the lifting clamp 431.
3. As shown in fig. 13, after the horizontal driving device 3 drives the vehicle body 2 to move above the mesh placement area, the lifting mechanism 432 works to control the lifting clamp 43 to descend to the mesh installation area, and the lifting clamp 433 releases the mesh to send the mesh to the mesh placement area. The mesh placement area can be provided with a corresponding fixing mechanism, the fixing mechanism can fix the relative positions of meshes and send the meshes into a mesh cage preparation device, and two meshes are prepared into a mesh cage as shown in fig. 9 by means of welding and the like. The fixing mechanism may have various structures such as a fixing member provided with two clamping grooves, a pair of clamping hands at fixed positions, and the like, and then is fed into the netpen preparation device through a trolley or a guide rail or the like.
In summary, according to the mesh placement method of the present embodiment, the mesh placement machine of embodiment 1 is adopted, so that the meshes stacked horizontally can be efficiently adjusted to be suitable for the mesh cage, and the production efficiency of the mesh cage is improved.
The examples of the present invention are merely for describing the preferred embodiments of the present invention, and are not intended to limit the spirit and scope of the present invention, and those skilled in the art should make various changes and modifications to the technical solution of the present invention without departing from the spirit of the present invention.
