When the vertical motor 511 is operated, the vertical driving shaft 512 rotates, so that the horizontal gear 513 and the horizontal rack 514 move relatively, the mesh sheet clamping device 4 moves downwards under the action of its own gravity, the vehicle body 2 is forced upwards, and the vehicle body 2 cannot be separated from the horizontal guide rail 32 because the horizontal sliding block 33 is mounted on the horizontal guide rail 32. When the vertical driving shaft 512 rotates in the opposite direction, the vehicle body 2 is forced downward, and the mesh gripping device 4 is lifted up by the support of the frame 1.
However, since the weight of the mesh gripping device 4 is large, the work load of the vertical driving device 5 is large, and therefore, the present embodiment is also equipped with the auxiliary device 7. As shown in fig. 1, the auxiliary device 7 includes an auxiliary bracket and an auxiliary cylinder, the auxiliary bracket is fixedly mounted on the vehicle body 2, the auxiliary cylinder is vertically and fixedly mounted on the auxiliary bracket, and the telescopic end of the auxiliary cylinder is connected with the mounting frame 41, so as to assist the lifting of the mesh sheet clamping device 4. Specifically, under the initial condition, the flexible end of auxiliary cylinder is in the state of minimum flexible distance, atmospheric pressure in the auxiliary cylinder keeps unanimous with the external world, press from both sides the decline of getting device 4 along with the net piece, atmospheric pressure in the auxiliary cylinder can change along with the flexible distance of flexible end, thereby press from both sides device 4 to the net piece and produce a pulling force, and press from both sides the difference of getting device 4 descending height along with the net piece, the pulling force size also can change along with the change of atmospheric pressure, thereby press from both sides the rising of getting device 4 for the net piece and provide the reset action, reduce vertical drive arrangement 5's work load.
In addition, in order to prevent the vehicle body 2 from being detached from the horizontal rail 32 and the vertical rail 52, the present embodiment is provided with a stopper 6 on the frame 1 at the extreme position where the vehicle body 2 moves in the horizontal direction. As shown in fig. 1 and 3, the limiting block 6 is an L-shaped structure, i.e., a section extends horizontally from the upper end of the limiting block 6. During operation, the mesh clamping position and the mesh placing position can be respectively arranged at two ends of the horizontal guide rail 32, when the vehicle body 2 reaches the position, the limiting block 6 is touched, on one hand, the vehicle body 2 can be prevented from being separated from the horizontal guide rail 32, and on the other hand, the positioning function can be achieved. And when the two positions are arranged, a section extending from the upper end of the limit block 6 is positioned 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.
In conclusion, the mesh arranging machine of the embodiment can automatically clamp and turn over the stacked meshes and adjust the distance between the two meshes, and then send the meshes into the fixing device for mesh cage production, so that the production efficiency of the mesh cage is effectively improved.
Example 2
A mesh placing method adopts the mesh placing machine of embodiment 1 to carry out mesh placing work, and the specific process is as follows.
Firstly, before starting, the horizontal driving device 3 drives the vehicle body 2 to move to the position above two adjacent stacks of net sheets, the net sheets are in a flat stacked state, then, as shown in fig. 10, the vertical driving device 5 works to drive the net sheet clamping device 4 to descend to the net sheet stacking position, and the overturning clamping hands 422 of the two overturning clamps 42 clamp the net sheets, so as to clamp one net sheet respectively.
Secondly, as shown in fig. 11, after the vertical driving device 5 drives the mesh sheet clamping device 4 to ascend, the turnover mechanism drives the turnover fixture 42 to rotate until the mesh sheet is in a vertical state, in this embodiment, the mesh sheet is turned inside by 90 °. Then, the cylinder I424 is driven to retract, and the reversing jig 42 is sent to a predetermined position, in this embodiment, two webs are sent to the lower side of the lifting/lowering gripper 433 on both sides of the lifting/lowering holder 431. Next, as shown in fig. 12, the lifting jig 43 is operated, the lifting grippers 433 on both sides of the lifting holder 431 clamp one mesh sheet, the reversing jig 42 releases the mesh sheet, the cylinder I424 is driven to operate, the reversing jig 42 returns to the initial position, the reversing jig 42 is controlled by the reversing mechanism to reverse 90 ° to return to the initial state, and the transfer of the two mesh sheets from the jig of the reversing jig 42 to the jig of the lifting jig 43 is completed. It should be noted that the distance between the two mesh sheets can be controlled by controlling the distance between the lifting handles 433 on the two sides of the lifting holder 431, so as to adjust the distance between the mesh sheets. If the lifting clamping hands 433 on both sides of the lifting clamping base 431 are fixed on both sides of the lifting clamping base 431, the distance between the two net sheets can be adjusted only by adjusting the width of the lifting clamping base 431.
Third, as shown in fig. 13, after the horizontal driving device 3 drives the vehicle body 2 to move above the mesh mounting region, the lifting mechanism 432 operates to control the lifting clamp 43 to descend to the mesh mounting region, and the lifting clamp 433 releases the mesh to send the mesh to the mesh mounting region. The mesh placing area can be provided with a corresponding fixing mechanism, the fixing mechanism can fix the relative positions of the meshes and send the meshes into a mesh cage preparation device, and the two meshes are prepared into a mesh cage shown in fig. 9 in a welding mode and the like. The fixing mechanism can have various structures, such as a fixing part with two clamping grooves, a pair of clamping hands at fixed positions and the like, and then the fixing mechanism is sent into the mesh cage preparation device through a trolley or a guide rail and the like.
In summary, in the mesh sheet placing method of the present embodiment, the mesh sheet placing machine of embodiment 1 can efficiently adjust the mesh sheets stacked in a horizontal manner to a position suitable for the cylinder mould, thereby improving the production efficiency of the cylinder mould.
