[0052] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict.

[0053] As shown in Figures 1 to 7 The mesh turning device of the embodiment includes a support frame 10, a mesh supporting platform 20, a transverse moving vehicle 30, a transverse moving driving mechanism 40, a lifting component 50, a lifting driving mechanism 60, and a mesh grabbing mechanism 70. The mesh supporting platform 20 is through in the support frame 10. The transverse moving vehicle 30 is movably arranged on the support frame 10 along the transverse direction of the support frame 10. The transverse moving driving mechanism 40 is connected with the transverse moving vehicle 30 to drive the transverse moving vehicle 30 to move transversely. The lifting component 50 is arranged on the transverse moving vehicle 30 in a lifting manner. The lifting driving mechanism 60 is connected with the lifting component 50 to drive the lifting component 50 to lift. The mesh grabbing mechanism 70 is arranged on the lifting component 50 and is used to grab the longitudinal rib 91 of one side of the mesh 90. Under the action of the transverse movement of the transverse moving vehicle 30 and the lifting of the lifting component 50, the mesh grabbing mechanism 70 vertically hangs the mesh 90 and then lowers the mesh 90 in the opposite direction to turn over the mesh 90.

[0054] The mesh overturning device is applied to place the mesh 90 on the mesh supporting platform 20, drive the horizontal moving trolley 30 to move to the left to align with the left side of the mesh 90 by the horizontal moving driving mechanism 40, lower the lifting component 50 by the lifting driving mechanism 60, so that the mesh grabbing mechanism 70 can grab the longitudinal rib 91 on the left side of the mesh 90, lift the mesh 90 by the lifting driving mechanism 60 until the whole mesh is separated from the mesh supporting platform 20, and then stop lifting; continue to drive the horizontal moving trolley 30 to move to the left by the horizontal moving driving mechanism 40, so that the lower end of the whole mesh is lower than the edge 21 on the left side of the mesh supporting platform 20, drive the horizontal moving trolley 30 to move to the right by the horizontal moving driving mechanism 40, and lower the lifting component 50 by the lifting driving mechanism 60, because the right side of the lower end of the mesh 90 is blocked by the edge 21 on the left side of the mesh supporting platform 20, the mesh is gradually laid flat on the mesh supporting platform 20 to the right; finally, the longitudinal rib 91 on the left side of the mesh grabbed by the mesh grabbing mechanism 70 has been transferred to the right side of the mesh supporting platform 20, so that the mesh overturning of 180° is realized. The mesh overturning device grabs the longitudinal rib 91 on the left side of the mesh 90, hangs the mesh from the left side, and then lays down to the right side, the mesh grabbing mechanism 70 can also grab the longitudinal rib 91 on the right side of the mesh 90, hangs the mesh from the right side, and then lays down to the left side, and the mesh overturning can also be realized. The mesh is grabbed by the mesh grabbing mechanism 70 on one side of the mesh, and then the mesh is overturned by the movement of the horizontal moving trolley 30 and the lifting of the lifting component, so that the mesh of different widths and the mesh with a width greater than 3m can be overturned, the mesh offset from the center of symmetry of the mesh supporting platform can be processed, and the selective overturning can be realized, that is, the mesh can be selected to be overturned or not.

[0055] It should be noted that up and down refer to the direction of the arrow in the middle Figure 5 , and left and right refer to the direction of the arrow in the middle. Figure 5

[0056] In the embodiment, the mesh grabbing mechanism 70 comprises a plurality of mesh grabbing assemblies arranged at intervals, each mesh grabbing assembly is movably arranged on the lifting component 50, and the mesh overturning device further comprises a moving driving mechanism 80 connected with the plurality of mesh grabbing assemblies to adjust the interval of the mesh grabbing assemblies. By driving the longitudinal movement of the mesh grabbing assembly, the mesh grabbing assembly can be matched with different horizontal rib intervals, so that the mesh grabbing assembly can avoid the horizontal rib and can adapt to the mesh of different lengths. It should be noted that the longitudinal direction refers to the extension direction of the longitudinal rib 91, and the transverse direction refers to the extension direction of the horizontal rib 92. Figure 5 In the embodiment, the left-right direction refers to the transverse direction.

[0057] In the embodiment, as Figure 7 and Figure 9 ​As shown, the net grabbing assembly is a hook assembly, each hook assembly comprising a hook base 71 movably arranged on the lifting member 50 and a hook 72 having an upper end hinged to the hook base 71 and a lower end having a hook body 721 adapted to hook the outermost longitudinal rib 91 of the net 90. The hook 72 is swingable relative to the hook base 71 so that each of the hooks 72 can hook the longitudinal rib 91, avoiding the case that the hook 72 cannot hook the longitudinal rib 91 due to processing error; the hook assembly has simple structure and does not need to be provided with a driving member, reducing cost. It can be understood that, as an alternative embodiment, the net grabbing assembly can also be a pneumatic gripper or the like.

[0058] Specifically, the number of the hook assemblies is four. It can be understood that the number of the hook assemblies can also be two or three, and is not limited thereto.

[0059] Preferably, in the hooking state, the hook body 721 of the hook 72 is in the hooking position, and in the unhooking state, the hook body 721 of the hook 72 is in the unhooking position. Figure 10 In the embodiment, the hook opening of the hook 72 is arranged towards the left, and it can be understood that the hook opening of the hook 72 can also be arranged towards the right.

[0060] In the embodiment, the hook assembly further comprises a hook locking mechanism arranged on the hook 72, the hook locking mechanism having a closed state of closing the hook opening of the hook body 721 and an open state of opening the hook opening. In the process of turning over, the hook locking mechanism closes the hook opening of the hook body 721, which can prevent the steel bars hooked by the hook 72 from falling off the hook opening during the net turning process, improving the safety in the net turning process.

[0061] In the embodiment, as shown in Figure 9 the hook locking mechanism comprises a hook locking rod 73 and a hook locking driving member 74, one end of the hook locking rod 73 is hinged to the hook body 721, the other end of the hook locking rod 73 is adapted to close or open the hook opening, and the hook locking driving member 74 is hinged to the part between the two ends of the hook locking rod 73 to drive the hook locking rod 73 to swing. The hook locking mechanism has simple structure and is easy to implement. Specifically, the hook locking driving member 74 is a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0062] In the embodiment, as shown in Figure 8As shown in the figure, the moving driving mechanism 80 comprises a moving driving member 81 and a first transmission mechanism 82. The moving driving member 81 is arranged on the hook seat 71, and the first transmission mechanism 82 is connected with the moving driving member 81 and the lifting component 50. The moving driving member 81 drives the hook seat 71 to move longitudinally through the first transmission mechanism 82. Specifically, the moving driving member 81 is an electric motor or a rotary cylinder, and the first transmission mechanism 82 is a gear and rack mechanism or a ball screw. When the first transmission mechanism 82 is the gear and rack mechanism, the gear and rack mechanism comprises a gear and a rack. The rack is fixed on the lifting component, and the gear is connected with the output shaft of the moving driving member 81. When the output shaft of the moving driving member 81 rotates, the gear rotates and moves on the rack, thereby driving the hook seat 71 to move. It can be understood that, as an alternative embodiment, the moving driving mechanism 80 is a linear driving mechanism such as a cylinder, an oil cylinder or an electric cylinder.

[0063] Preferably, a first guide mechanism is arranged between the hook seat 71 and the lifting component 50. The first guide mechanism guides the movement of the hook seat 71, thereby ensuring the movement accuracy. The first guide mechanism is a linear slide rail. It can be understood that, as an alternative embodiment, the first guide mechanism comprises a guide shaft and a guide seat. The guide shaft is fixed on the lifting component, and the guide seat is fixed on the hook seat 71. The guide shaft is arranged in the guide hole of the guide seat.

The grabbing net mechanism 70 is arranged on the hanging beam 52, and the hanging beam 52 is arranged to facilitate the installation of the grabbing net mechanism 70. Specifically, the lifting frame 51 is a frame structure. It can be understood that, as an alternative embodiment, the hanging beam 52 is not arranged, and the grabbing net mechanism 70 is directly installed on the lifting frame 51.

[0065] In the embodiment, as shown in the figure, Figure 2 and Figure 4 the lifting driving mechanism 60 comprises a lifting driving member 61 and a second transmission mechanism 62. The lifting driving member 61 is arranged on the horizontal moving vehicle 30, and the second transmission mechanism 62 is connected with the lifting driving member 61 and the lifting component 50. The lifting driving member 61 drives the lifting component 50 to lift through the second transmission mechanism 62. Specifically, the lifting driving member 61 is an electric motor or a rotary cylinder, and the second transmission mechanism 62 is a gear and rack mechanism or a ball screw. When the second transmission mechanism 62 is the gear and rack mechanism, the rack of the gear and rack mechanism is fixed on the lifting component, and the gear of the gear and rack mechanism is connected with the output shaft of the lifting driving member 61. The lifting driving member 61 is fixed on the horizontal moving vehicle 30. When the output shaft of the lifting driving member 61 rotates, the gear rotates and moves on the rack, thereby driving the lifting component 50 to lift. It can be understood that, as an alternative embodiment, the lifting driving member 61 is a linear driving mechanism such as a cylinder, an oil cylinder or an electric cylinder, or a hoist.

[0066] Preferably, a second guiding mechanism is arranged between the lifting component 50 and the transverse moving trolley 30, which guides the lifting of the lifting component 50 and ensures the movement accuracy. The specific structure of the second guiding mechanism is the same as that of the first guiding mechanism, which will not be described in detail here.

[0067] In the embodiment, as shown in Figure 1 and Figure 2 , the transverse moving driving mechanism 40 comprises a transverse moving driving component 41 arranged on the transverse moving trolley 30 and a third transmission mechanism connected with the transverse moving driving component 41 and the support frame 10, and the transverse moving driving component 41 drives the transverse moving trolley 30 to move transversely through the third transmission mechanism. Specifically, the transverse moving driving component 41 is a motor or a rotary cylinder, and the third transmission mechanism is a gear and rack mechanism or a ball screw, etc. When the third transmission mechanism is a gear and rack mechanism, the rack of the gear and rack mechanism is fixed on the support frame, the gear of the gear and rack mechanism is connected with the output shaft of the transverse moving driving component 41, the output shaft of the transverse moving driving component 41 rotates, and in turn drives the gear to rotate and move on the rack, so as to move the transverse moving trolley 30.

[0068] In the embodiment, a third guiding mechanism is arranged between the support frame 10 and the transverse moving trolley 30, which guides the transverse movement of the transverse moving trolley 30 and ensures the movement accuracy. Specifically, as shown in Figure 3 , the third guiding mechanism comprises a guiding wheel and a guide rail 421, the guiding wheel walks on the guide rail 421, and the guiding wheel is in rolling fit with the guide rail 421 to reduce the abrasion. Preferably, the guiding wheel comprises a top guiding wheel 422 and a side guiding wheel 423, the top guiding wheel 422 is fitted with the top surface of the guide rail 421, and the side guiding surface is fitted with the side surface of the guide rail 421. It can be understood that the third guiding mechanism can also have the same specific structure as the first guiding mechanism, which will not be described in detail here.

[0069] It should be noted that the specific structures of the moving driving mechanism, the lifting driving mechanism and the transverse moving driving mechanism are not limited to the above structures, and any form of driving mechanism can be used as long as it can realize movement.

[0070] In the embodiment, as shown in Figure 1 , the turnover device further comprises a bracket 100 and a towing trolley 110, the bracket 100 is arranged through the support frame 10, the towing trolley 110 is movably arranged on the bracket 100, the net platform 20 is located inside the bracket 100, and the net piece 90 is towed to the net platform 20 by the towing trolley 110. The towing trolley 110 can adopt the structure in the prior art, which will not be described in detail here.

[0071] The present application also provides a net piece turnover method, which comprises the following steps:

[0072] Placing the net 90 on the net supporting platform 20;

[0073] Controlling the horizontal moving driving mechanism 40 to drive the horizontal moving vehicle 30 to move until the net grabbing mechanism 70 moves to one side of the net 90;

[0074] Controlling the net grabbing mechanism 70 to grab the longitudinal rib on one side of the net 90 and hang the net 90 vertically;

[0075] Controlling the horizontal moving driving mechanism 40 to drive the horizontal moving vehicle 30 to move until the net 90 is located on one side of the net supporting platform 20;

[0076] Controlling the lifting driving mechanism 60 to drive the lifting component 50 to descend until the lowermost end of the net 90 is lower than the top surface of the net supporting platform 20;

[0077] Controlling the horizontal moving driving mechanism 40 to drive the horizontal moving vehicle 30 to move to the other side of the net supporting platform 20 while controlling the lifting driving mechanism 60 to drive the lifting component 50 to descend, the lowermost end of the net 90 is blocked by one side of the net supporting platform 20, and the net 90 is gradually laid flat on the net supporting platform 20 to complete the turning of the net 90.

[0078] The above-mentioned net turning method can grab the longitudinal rib 91 on the leftmost side of the net 90, hang the net from the left side and lay it down to the right side, the net grabbing mechanism 70 can also grab the longitudinal rib 91 on the rightmost side of the net 90, hang the net from the right side and lay it down to the left side, and the net turning can also be achieved. By grabbing the longitudinal rib 91 on one side of the net 90 through the net grabbing mechanism 70 and then turning the net through the movement of the horizontal moving vehicle 30 and the lifting of the lifting component, the net of different widths and the net with a width greater than 3m can be turned, the net offset from the center of symmetry relative to the net supporting platform can be processed, and selective turning can be achieved, i.e., turning or not turning can be selected.

[0079] In the embodiment, the net grabbing mechanism 70 includes a plurality of interval arranged net grabbing assemblies, and before the step of controlling the net grabbing mechanism 70 to grab the longitudinal rib on one side of the net 90, it further includes: controlling the moving driving mechanism 80 to drive the net grabbing assemblies to move according to the interval of the transverse rib of the net to adjust the interval of the net grabbing assemblies, so as to match different transverse rib intervals, so that the net grabbing assemblies can avoid the transverse rib and can adapt to nets of different lengths.

[0080] In the embodiment, in the step of controlling the horizontal movement driving mechanism 40 to drive the horizontal movement trolley 30 to move until the net grabbing mechanism 70 moves to one side of the net 90, the horizontal movement driving mechanism 40 is controlled to drive the horizontal movement trolley 30 to move until the hook assembly of the net grabbing mechanism 70 is aligned with the net hole on one side of the net 90; the step of controlling the net grabbing mechanism 70 to grab the longitudinal rib on one side of the net 90 and vertically hang the net 90 includes: controlling the lifting driving mechanism 60 to drive the lifting component 50 to descend until the hook assembly is inserted into the net hole; controlling the horizontal movement driving mechanism 40 to drive the horizontal movement trolley 30 to move until the hook assembly hooks the longitudinal rib towards the hook opening; controlling the lifting driving mechanism 60 to drive the lifting component 50 to ascend until the net 90 is vertically hung. In the step of controlling the net grabbing mechanism 70 to release the longitudinal rib of the net 90, the lifting driving mechanism 60 is controlled to drive the lifting component 50 to descend until the hook assembly is separated from the longitudinal rib. By hooking the longitudinal rib through the hook assembly, the structure of the hook assembly is simple, and no driving component is needed, thereby reducing the cost.

[0081] It can be understood that, as an alternative embodiment, the net grabbing assembly can also adopt a pneumatic gripper or the like. In the step of controlling the horizontal movement driving mechanism 40 to drive the horizontal movement trolley 30 to move until the net grabbing mechanism 70 moves to one side of the net 90, the horizontal movement driving mechanism 40 is controlled to drive the horizontal movement trolley 30 to move until the pneumatic gripper of the net grabbing mechanism 70 is aligned with the longitudinal rib on one side of the net 90; the step of controlling the net grabbing mechanism 70 to grab the longitudinal rib on one side of the net 90 and vertically hang the net 90 includes: controlling the lifting driving mechanism 60 to drive the lifting component 50 to descend until the longitudinal rib is located in the pneumatic gripper; controlling the pneumatic gripper to clamp the longitudinal rib; controlling the lifting driving mechanism 60 to drive the lifting component 50 to ascend until the net 90 is vertically hung.

[0082] In the embodiment, after the step of gradually laying the net 90 on the net supporting platform 20, the method further includes: controlling the lifting driving mechanism 60 to stop driving the lifting component 50; controlling the horizontal movement driving mechanism 40 to drive the horizontal movement trolley 30 to continue moving to the other side of the net supporting platform 20, and after the net 90 is dragged to a preset position, controlling the horizontal movement driving mechanism 40 to stop driving the horizontal movement trolley 30; and controlling the net grabbing mechanism 70 to release the longitudinal rib of the net 90 and reset to the initial position. Dragging the net 90 to the preset position facilitates cooperation with the drag net mechanism and facilitates conveying the turned-over net.

[0083] In the embodiment, after the step of vertically hanging the net 90, the method further includes: controlling the locking mechanism of the hook assembly to close the hook opening of the hook assembly; and before the step of controlling the net grabbing mechanism 70 to release the longitudinal rib of the net 90, the method further includes: controlling the locking mechanism of the hook assembly to open the hook opening of the hook assembly. In the turning process, the locking mechanism closes the hook opening of the hook body 721, which can prevent the steel bar hooked by the hook 72 from falling off from the hook opening in the turning process, thereby improving the safety in the turning process.

[0084] The specific action process of the mesh turning device is described as follows: Figures 10 to 27 The specific action process of the mesh turning device is described as follows:

[0085] 1. The net car 110 drags the mesh 90 to the net supporting platform 20 below the hook assembly, and then completely withdraws from the turning area;

[0086] 2. The horizontal moving vehicle 30 is moved to align the mesh hole right to the leftmost longitudinal rib 91 of the mesh, and the hook assembly is lowered to insert the hook 72 into the mesh hole right to the leftmost longitudinal rib 91; wherein, Figure 10 The mesh hole right to the leftmost longitudinal rib 91 is between the two vertical dashed lines;

[0087] 3. The horizontal moving vehicle 30 is moved to the left by a certain distance, so that the hook 72 is inclined to lean on the leftmost longitudinal rib 91 of the mesh;

[0088] 4. The hook assembly is lifted up, and the hook 72 will automatically hook the leftmost longitudinal rib 91 of the mesh during the lifting process, and the mesh 90 is hung up, until the whole mesh is completely separated from the net supporting platform 20, and then the lifting is stopped;

[0089] 5. After the mesh 90 is completely vertical, the locking mechanism on the hook 72 is closed to prevent the steel bar from falling out of the hook opening of the hook 72 during the subsequent action process;

[0090] 6. The horizontal moving vehicle 30 carries the hook assembly and the hooked mesh to the left to move the vertical surface of the mesh to the left side of the leftmost edge 21 of the net supporting platform 20;

[0091] 7. The hook assembly is lowered so that the lower end of the mesh is lower than the leftmost edge 21 of the net supporting platform 20;

[0092] 8. The horizontal moving vehicle 30 is moved to the right and the hook assembly is lowered at the same time. Since the right side of the lower end of the mesh is blocked by the leftmost edge 21 of the net supporting platform 20, the mesh 90 is gradually laid flat to the right on the net supporting platform 20. Finally, the leftmost longitudinal rib 91 of the mesh 90 hooked by the hook 72 has been transferred to the rightmost side of the net supporting platform 20, thereby realizing the 180° turning of the mesh;

[0093] 9. When the mesh 90 just falls on the net supporting platform 20, the lowering action of the hook assembly is stopped, and at this time the hook 72 is not completely separated from the longitudinal rib 91 hooked by it. The horizontal moving vehicle 30 is further moved to the right, and the mesh is dragged to the right to the designated position by the hook 72, and the horizontal moving vehicle 30 stops moving;

[0094] 10. The locking mechanism on the hook 72 is opened to facilitate unhooking later;

[0095] 11. The hook assembly is lowered until the hook 72 is completely out of the longitudinal bar 91 hooked by it, then the traversing vehicle 30 moves a certain distance to the right, so that the hook 72 moves out of the lower side of the longitudinal bar 91 hooked by it, and finally the hook assembly is lifted to the initial height, waiting for the next turnover cycle.

[0096] By hooking the outermost longitudinal bar 91 of the mesh with multiple hooks and lifting the mesh, and then lowering the mesh in the opposite direction, the offset mesh and mesh of different widths can be adapted.

[0097] It should be noted that in Figures 10 to 27 , the horizontal arrow refers to the moving direction of the traversing vehicle, the vertical arrow refers to the moving direction of the lifting component, and the inclined arrow refers to the moving direction of the locking rod.

[0098] The present application also provides a reinforcing steel bar processing production line, which comprises the mesh turnover device described above. Through the lifting and traversing actions of the lifting component 50 of the mesh turnover device and the traversing vehicle 30, the mesh can be lifted from one side to a vertical state by the hook, and then lowered to the opposite side, thereby completing the turnover of the mesh, i.e. the mesh is lifted from one side to the other side by the hook, thereby realizing the turnover of the mesh. The action is less, the structure is simple, the cost is low, different width meshes can be simultaneously adapted, and offset meshes can be processed.

[0099] In the present embodiment, the reinforcing steel bar processing production line comprises a bar distribution device, a straightening device, a bending device, etc. The straightening device and the bending device can adopt the structure in the prior art, which will not be described in detail here.

The traversing vehicle 30 is installed on the top of the support frame 10 and can be moved horizontally. Through the lifting and horizontal actions of the lifting component 50 and the traversing vehicle 30, the hook assembly can hang and stand the horizontal mesh, and then lower the mesh in the opposite direction, thereby completing the turnover of the mesh. The structure is simple, the cost is low, and different width meshes can be simultaneously adapted.

[0102] 2. The lifting component 50 comprises a lifting frame 51 and a hoisting beam 52. The number of hook assemblies is two or more and is arranged on the hoisting beam 52. The length direction of the hoisting beam 52 is parallel to the extension direction of the longitudinal bar 91 of the reinforcing steel mesh, so that the multiple hook assemblies on the hoisting beam can hook the same longitudinal bar.

[0103] 3. The hook assembly can move in parallel with the length of the beam 52 to adapt to different length of mesh and to avoid the cross rib 92.

[0104] 4. The hook assembly includes the hook 72 and the hook base 71, the hook 72 is hinged on the hook base 71 by the pin 75 and can swing around the hinge point, and multiple hooks 72 can hook the longitudinal rib to avoid the situation that the hook 72 cannot hook the longitudinal rib due to processing error.

[0105] 5. The hook 72 is provided with a locking mechanism to prevent the steel bar hooked by it from falling off the hook opening during the mesh turning process.

[0106] 6. The lateral moving distance of the lateral moving vehicle 30 can adapt to different width of mesh according to the design of the mesh with the maximum width of the steel mesh production line; the mesh turning device can be separated from the mesh conveying channel below it as a whole to let the mesh go in and out freely, and the mesh can be turned or not.

Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be exhausted and the changes or variations derived from them are still within the protection scope of the present application.
