[0039] In order to better explain the present invention and facilitate understanding, the following Figure 1-7 , the utility model is described in detail through specific implementation methods. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is used as a reference.

[0040] Embodiment 1:

[0041] Reference Figure 1-Figure 7The embodiment of the utility model provides a mesh grabbing and delivering device, including a frame, a sliding device 1, a rotating device 2, a lifting device 3 and a grabbing device 4, the sliding device 1 can drive the rotating device 2 to slide along a first direction relative to the frame, the rotating device 2 can drive the lifting device 3 to rotate vertically, the lifting device 3 can drive the grabbing device 4 to rise and fall, and the grabbing device 4 can grab the mesh 5; the grabbing device 4 includes a hanger 41, a plurality of adjustment mechanisms 42 and a plurality of clamping claw assemblies 43, the fixed end of the adjustment mechanism 42 is connected to the hanger 41, and the clamping claw assembly 43 is connected to the movable end of the adjustment mechanism 42; the clamping claw assembly 43 includes a clamping end 431, and the mesh 5 has a plurality of clamping positions A, and the movable end of the adjustment mechanism 42 can slide laterally relative to the hanger 41, thereby adjusting the lateral position of the clamping claw assembly 43 so that the position of the clamping end 431 matches the position of the clamping position A, and the grid of the mesh 5 forms the clamping position A.

[0042] Specifically, the first direction is a horizontal direction extending laterally, and may be a left-right direction.

[0043] In this embodiment, the sliding device 1 can slide along the first direction, thereby driving the rotating device 2 to slide synchronously; the rotating device 2 can rotate longitudinally and drive the lifting device 3 to rotate; the lifting device 3 can drive the grasping device 4 to rise and fall, therefore, the mesh 5 grasped by the grasping device 4 can not only slide along the first direction, but also rotate vertically and linearly, and can also be lifted and lowered, so that the mesh 5 can be flexibly moved to the desired position, and obstacle avoidance can be achieved during the movement, such as avoiding obstacles in the site by moving along the first direction and rotating vertically, and at the same time, the position and direction of the mesh plate 5 can be matched with the position and direction required by the construction station D on the processing line, thereby improving the flexibility of the mesh 5 feeding operation.

[0044] At the same time, since the mesh 5 itself is a grid rotating frame 72 structure and it is not a rigid part in the traditional sense, the utility model makes targeted improvements to the grasping device 4 for grasping it.

[0045] Specifically, the clamping positions A of the mesh 5 can be the four corners on the outside of the mesh 5, and the clamping positions can be separate ribs of the mesh 5. The clamping end 431 includes two clamping blocks that can move closer to or farther from each other.

[0046] There are evenly distributed mesh holes on the mesh 5, and the clamping end 431 of the clamping jaw assembly 43 can specifically clamp the mesh hole positions, so that the two clamping blocks of the clamping jaw assembly 431 can be inserted into the mesh holes and clamped on the tendons of the mesh 5. In addition, the clamping jaw assembly 43 can change the horizontal position under the adjustment of the adjustment mechanism 42, so that the two clamping blocks of the clamping jaw assembly 431 can actively avoid the tendons of the mesh 5 during the process of inserting the mesh holes, and at the same time, each clamping end 431 can maintain a state of evenly clamping the mesh 5, thereby improving the balance of the mesh 5 after being clamped, and preventing the deformation of the mesh 5 from affecting its own quality.

[0047] Specifically, the clamping jaw assembly 43 is an existing automatic clamp, but the vertical projection of the clamping block size needs to be smaller to ensure that it can be inserted into the mesh, and at the same time, when the two clamping blocks are away from each other, they do not interfere with the ribs of the mesh plate.

[0048] In this embodiment, the mesh grabbing and delivering device is supported on a base plate 6, a clearance opening B is provided on the base plate 6, and a construction space C is formed below the base plate 6. The mesh grabbing and delivering device can make the mesh 5 pass through the clearance opening B and then descend to the construction space C.

[0049] Specifically, the substrate 6 can be the second floor of the factory, the sliding device 1 is supported on a gantry, the gantry is supported on the substrate 6, the construction space C below the substrate 6 is a first floor of the factory, and the mesh is connected to the concrete slab production line, so that the mesh grabbing and delivering equipment as the feeding line and the concrete component production line as the circulating processing line 8 can be arranged vertically in a stacked manner to save factory space, improve factory space utilization, and reduce the production cost of concrete slabs.

[0050] In this embodiment, the adjustment mechanism 42 includes a first telescopic driving member 421, a connecting plate 422 and a second telescopic driving member 423; the fixed end of the first telescopic driving member 421 is connected to the hanger 41, the connecting plate 422 is slidably connected to the hanger 41 along the telescopic direction of the second telescopic driving member 423, the connecting plate 422 is drivingly connected to the telescopic end of the first telescopic driving member 421, the fixed end of the second telescopic driving member 423 is connected to the connecting plate 422, and the body of the clamping jaw assembly 43 is drivingly connected to the telescopic end of the second telescopic driving member 423; wherein the telescopic directions of the first telescopic driving member 421 and the second telescopic driving member 423 are both horizontal and cross each other.

[0051] In this embodiment, driven by the first telescopic driving member 421 and the second telescopic driving member 423 , the clamping jaw assembly 43 can achieve sliding in two directions, so that the position of the clamping end 431 can accurately match the clamping position A of the mesh 5 .

[0052] At the same time, even if the parameters such as the form and density of the grid of the mesh 5 change, the clamping end 431 can be adjusted under the action of the adjustment mechanism 42, so that the clamping end 431 can always achieve good matching and reliable clamping with the mesh 5.

[0053] Furthermore, the telescopic directions of the first telescopic driving member 421 and the second telescopic driving member 423 are perpendicular to each other, which enables the grasping device 4 to realize two-axis movement in a plane and also makes the position adjustment of the grasping device 4 more standardized, which is beneficial to improving the adjustment accuracy of the position of the grasping device 4.

[0054] In this embodiment, the sliding device 1 includes a track 11 , a sliding frame 12 slidably connected to the track 11 along a first direction, and a sliding driving member 13 for driving the sliding frame 12 to slide along the track 11 .

[0055] In this embodiment, the rail 11 is supported on the gantry, the rail 11 may be an I-rail, and the sliding frame 12 is slidably connected to the rail 11 via a sliding block.

[0056] Specifically, the sliding drive member 13 includes a motor 131, a gear 132 and a rack 133. The rack 133 is directly or indirectly connected to the track 11 and is consistent with the extension direction of the track 11; the gear 132 is drivingly connected to the torque output end of the motor 131 and meshes with the rack 133. In this way, when the motor 131 is running, the gear 132 will interact with the rack 133, thereby pushing the sliding frame 12 to slide relative to the track 11.

[0057] This embodiment provides one form of the sliding drive member 13. Other drive members that can make the sliding frame 12 slide along the track 11, such as electric telescopic rods, telescopic cylinders and other drive members, are all within the protection scope of the present utility model.

[0058] In this embodiment, the rotating device 2 includes a turntable 21 and a turntable driving member 22 . The fixed end of the turntable driving member 22 is connected to the sliding frame 12 , and the turntable 21 is connected to the rotating end of the turntable driving member 22 .

[0059] Specifically, the rotary drive member 22 may be a rotary cylinder, and the rotary table 21 may be a frame 72 platform, and the rotary cylinder can drive the frame 72 platform to rotate to a limited position. Under the action of the rotary drive member 22, the mesh 5 can rotate along a vertical straight line, thereby further improving the flexibility of the position adjustment of the mesh 5 and the adaptability to the use scenario.

[0060] The lifting device 3 includes a plurality of hoists 31 horizontally distributed on the turntable 21 , and the lifting ends of the hoists 31 are connected to the hanger 41 .

[0061] The lifting end of the hoist 31 is the end of the wire rope. At the same time, multiple groups of hoists 31 are evenly distributed on the turntable 21 to improve the lifting stability of the hanger 41.

[0062] The mesh grabbing and delivering equipment also includes a placement stand 7 for storing the mesh 5 to achieve the positioning of the mesh 5; the placement stand 7 includes a laterally extending placement platform 71, and a frame 72 connected to the outer periphery of the platform and extending vertically, the inner wall of the frame 72 and the placement platform 71 form a placement space with an open top, and the mesh 5 is stacked and placed in the placement space.

[0063] In this embodiment, the mesh 5 is stored in the placement stand 7 and stacked to limit the position of the mesh 5. In this way, after the position of the clamp assembly 43 is adjusted once, the same type of mesh 5 can be grasped, thereby improving the grasping efficiency of the mesh 5.

[0064] There is a clearance fit between the mesh 5 and the inner wall of the frame 72, and the clearance is smaller than the spacing of one mesh hole. For example, the clearance can be controlled to be about 0.5 mm.

[0065] At the same time, a partition 73 is provided between adjacent meshes 5 to separate the adjacent meshes 5, so that the distance between adjacent meshes 5 is greater than the vertical clamping length of the clamping end 431, thereby ensuring that the adjacent meshes 5 always remain in a mutually separated state, avoiding the jaw assembly 43 from mistakenly grabbing multiple stacked meshes 5 when grabbing the mesh 5, thereby improving the reliability of the mesh 5 grabbing operation.

[0066] Specifically, the separator 73 may include two knobs and a connecting rod connecting the knobs. The connecting rod and the knobs are threadedly connected. The two knobs are parallel to each other and coaxial with the connecting rod. The two knobs can be moved closer to or farther away from each other by adjustment, thereby increasing or decreasing the separation distance of the separator 73 for adjacent meshes 5.

[0067] Embodiment 2:

[0068] Reference Figure 7 In addition to providing a concrete slab production line, the embodiment of the utility model includes a mesh grabbing and delivering device as in Example 1, and also includes a circulating processing line 8, which is located in the construction space C. A construction station D is formed on the circulating processing line 8, and the construction station D corresponds to the descending position of the mesh 5 after passing through the make way opening B.

[0069] In this embodiment, the construction station D corresponds to the installation station of the mesh 5, that is, the opening B faces the installation station of the mesh 5, which can improve the production efficiency of the concrete slab.

[0070] The circulation processing line 8 is a vertical stacking circulation processing line, so as to further reduce the horizontal space occupation of the factory building and improve the vertical space utilization rate.

[0071] Embodiment 3:

[0072] The embodiment of the utility model provides a mesh grabbing and placing method, which is applied to the concrete slab production line in the above technical solution, and the method comprises:

[0073] S1: Based on the lifting device 3, the grabbing device 4 is switched to a lifting position away from the mesh 5, and the sliding device 1, the rotating device 2 and the adjusting mechanism 42 are controlled to align the clamping end 431 with the clamping position A;

[0074] S2: Control the lifting device 3 to descend to a grabbing position close to the mesh 5 so that the clamping end 431 clamps the mesh 5;

[0075] S3: Control the grabbing device 4 to switch to the lifting position, and at the same time control the sliding device 1 to drive the rotating device 2 to slide along the first direction relative to the frame until the mesh 5 is aligned with the position of the clearance opening B;

[0076] S4: Control the rotating device 2 to drive the lifting device 3 to rotate until the grabbing device 4 and the mesh 5 can pass through the clearance opening;

[0077] S5: Control the lifting device 3 to drive the grabbing device 4 to descend, so that the grabbing device 4 and the mesh 5 pass through the clearance opening;

[0078] S6: Control the rotating device 2 to rotate so that the direction of the mesh 5 matches the direction of the mesh 5 required by the construction station D;

[0079] S7: Control the lifting device 3 to drive the grabbing device 4 to descend, so that the mesh 5 descends into the construction station D.

[0080] It can be seen that in this method, the mesh 5 and the grabbing device 4 need to match the direction of the make way opening, thereby ensuring that the mesh 5 and the grabbing device 4 do not interfere with the side wall of the material distribution opening, and at the same time, the mesh 5 can match the arrangement direction of the mesh 5 required by the construction station, thereby improving the arrangement flexibility of the concrete production line and making it not restricted by the direction of the mesh 5.

[0081] In this way, the mesh grabbing and delivery equipment and the circulation processing line can be independent of each other, and both will have high layout flexibility to adapt to the actual needs of the factory. For example, the mesh delivery equipment can be used in the actual scenario where the floor beam of the second-floor space in the factory only supports a long-extending opening B along the front opening, and the extension of the opening B to the left and right will destroy the structure of the floor beam itself, while the arrangement direction of the mesh 5 required by the construction station on the circulation processing line in the first-floor construction space C is extended to the left and right.

[0082] When one mesh 5 is placed, the above steps are reversed to reset the grabbing device 4, and then steps S1 to S7 are repeated to place the mesh 5 again.
