Technical Field
[0001] The invention belongs to the technical field of mesh grabbing devices and grabbing methods, and in particular relates to a device for grabbing stacked meshes piece by piece and a method for grabbing meshes using the device. Background Art
[0002] In order to facilitate production and storage on the production line, meshes welded by welding machines are often stacked together to form stacked meshes after welding on the welding production line. In order to reprocess the meshes on the stacked meshes, it is necessary to remove the single meshes from the mesh stack. Currently, there are two main ways to take them: First, manual taking, two workers grab the meshes and remove the top meshes from the mesh stack. This method has the following defects: First, the mesh stack is generally more than two meters high. When taking the upper mesh, you need to use a stool, etc. As the mesh stack is lowered, the mesh at the bottom needs to bend over to take it, which is labor-intensive and inefficient; Second, there are burrs around the mesh, which can easily cause injuries to people. Secondly, mechanical grabbing is adopted, and a grabber or an electromagnet is arranged on the hanger, and the mesh is grabbed by the grabber or the electromagnet. This method has the following defects: the stacked mesh has poor flatness due to various reasons, and some grabbers cannot grab the mesh during grabbing, causing the mesh to fall off or tilt, which will have a certain impact on the quality of the mesh. Due to the different mesh sizes of the mesh, the magnetic force of the electromagnet is not easy to control, which can easily cause two layers of mesh to be sucked at the same time in some positions, and some positions cannot suck any mesh firmly. Summary of the invention
[0003] The first technical problem to be solved by the present invention is to provide a device for grabbing stacked mesh pieces one by one, which has low labor intensity, high production efficiency, simple structure, no damage to the mesh pieces, good mesh flatness, and is suitable for assembly line operation.
[0004] In order to solve the above problems, the technical solution adopted by the stacking mesh piece-by-piece grabbing device of the present invention is: it includes a hanger and a plurality of grabbing mechanisms located below the hanger; the grabbing mechanism includes a hanger located above, a guide sleeve is arranged below the hanger, a lifting rod with a lifting nut on the upper end is arranged in the guide sleeve, the lifting nut is located above the hanger, a grabbing head is arranged below the lifting rod, the grabbing head includes a head fixing seat and a grabbing cylinder located above the head fixing seat, the lower end of the lifting rod is connected to the head fixing seat, a grabbing cover is arranged below the head fixing seat, the top rod of the grabbing cylinder is connected to the grabbing claw through a connecting rod, and the lower end of the grabbing claw extends out from below the grabbing cover; a photosensitive switch is arranged above the hanger, and the photosensitive switch is located on the side of the lifting nut.
[0005] Its additional technical features are: A slide plate groove is arranged on the side of the grab cover, an adjustment slide plate is arranged on the outside of the slide plate groove, and the adjustment slide plate is fixed to the grab cover by an adjustment bolt; The hanger comprises a transverse hanger rod and a plurality of longitudinal hangers, wherein a transverse track is arranged on the transverse hanger rod, and a transverse track slider with a transverse track slot is arranged on each of the longitudinal hangers, wherein the transverse track is clamped in the transverse track slot; a longitudinal track is arranged on the longitudinal hanger rod, and a hanger seat track slider with a longitudinal track slot is arranged on the hanger seat, wherein the longitudinal track is clamped in the longitudinal track slot, and a fastening bolt locked with the hanger seat is arranged on the hanger seat track slider; A wire slot is arranged on the longitudinal suspension rod, and a wire slot card is arranged outside the wire slot.
[0006] The second technical problem to be solved by the present invention is to provide a method for grabbing mesh sheets using the above-mentioned device for grabbing the stacked mesh sheets one by one.
[0007] In order to solve the above problems, the technical solution adopted by the method of grabbing mesh sheets by the above-mentioned stacked mesh sheet grabbing device is as follows: The method comprises the following steps: The first step is to place the stacking mesh piece by piece grabbing device directly above the stacking mesh. The stacking mesh piece-by-piece grabbing device is placed just above the stacking mesh piece by a hoisting device with a lifting motor; In the second step, the stacking mesh piece grabbing device descends one by one, and at the same time, the top rod of the grabbing cylinder pushes down and the gripper is in an open state. The lifting motor rotates, driving the stacking mesh piece-by-piece grabbing device to descend. At the same time, the top rod of the grabbing cylinder pushes down, and the grabbing claw is in an open state; The third step is to slow down the descending speed of the lifting motor and slow down the descending speed of the stacking mesh piece-by-piece grabbing device. During the descending process of the stacking mesh piece grabbing device, the grabbing head of each grabbing mechanism is under the action of its own gravity, the lifting rod is located at the bottom of the guide sleeve, and the lifting nut is located below the photosensitive switch. When the lower end of the grabbing cover of at least one grabbing mechanism contacts the mesh, the horizontal wire or the vertical wire of the mesh is located in the open gripping claw, and the grabbing head of the grabbing mechanism drives the lifting rod to push up, and the lifting nut moves up, triggering the photosensitive switch, and the photosensitive switch transmits the signal to the lifting motor, and the rotation speed of the lifting motor decreases; Step 4: The lifting motor stops rotating, and the stacking mesh piece-by-piece grabbing device stops descending. As the stacking mesh piece grabbing device slowly descends, the grabbing mechanism that first touches the mesh piece is supported by the uppermost mesh piece, and the grabbing head drives the lifting push rod to continue to move up along the guide sleeve, while the grabbing mechanism that does not touch the mesh piece moves down with the hanger of the stacking mesh piece grabbing device, and the lower end of the grabbing cover of the grabbing mechanism gradually touches the mesh piece, and the horizontal wire or the longitudinal wire of the mesh piece is located in the open gripping claw. When the lower ends of the grabbing covers of all the grabbing mechanisms touch the mesh piece, the photosensitive switch transmits a signal to the lifting motor, the lifting motor stops rotating, and the stacking mesh piece grabbing device stops descending; Step 5: Grab the top mesh The top rods of all grabbing cylinders retract and the claws grab the mesh; Step 6: The stacking mesh piece by piece grabbing device rises The lifting motor rotates, driving the stacking mesh piece-by-piece grabbing device to rise, and the first mesh piece located above the stacking mesh piece is grabbed; Step 7: Move the captured mesh to the required position. Lift the mesh to the required position through the lifting device; Step 8: Put down the mesh The top rod of the grabbing cylinder pushes down, the claws release, and the mesh falls from the stacking mesh piece by piece grabbing device; Step 9: Repeat steps 1 to 8 until the entire stack of mesh is grabbed.
[0008] As a further improvement, for a stacking mesh piece-by-piece grabbing device having an adjusting slide disposed on the side of a grabbing cover, a method for grabbing mesh pieces using the stacking mesh piece-by-piece grabbing device comprises the following steps: Before placing the stacking mesh piece-by-piece grabbing device just above the stacking mesh in the first step, first adjust the distance from the lower end of the adjustment slide to the lower edge of the grabbing cover according to the thickness of the junction of the transverse wires and the longitudinal wires of the mesh, so that the distance from the lower edge of the closed space formed after the gripping claws are engaged to the lower edge of the adjustment slide is slightly larger than the thickness of the junction of the transverse wires and the longitudinal wires of the mesh, and then proceed to the subsequent steps.
[0009] Compared with the prior art, the device for grabbing stacked mesh sheets one by one and the method for grabbing mesh sheets using the device provided by the present invention have the following advantages: Firstly, it includes a hanger and a plurality of grabbing mechanisms located below the hanger; the grabbing mechanism includes a hanger located above, a guide sleeve is arranged below the hanger, a lifting rod with a lifting nut at the upper end is arranged in the guide sleeve, the lifting nut is located above the hanger, a grabbing head is arranged below the lifting rod, the grabbing head includes a head fixing seat and a grabbing cylinder located above the head fixing seat, the lower end of the lifting rod is connected to the head fixing seat, a grabbing cover is arranged below the head fixing seat, the top rod of the grabbing cylinder is connected to the grabbing claw through a connecting rod, and the lower end of the grabbing claw extends out from below the grabbing cover; a photosensitive switch is arranged above the hanger, and the photosensitive switch is located on the side of the lifting nut. The piece-by-piece grabbing device for the stacking mesh is placed just above the stacking mesh by a hoisting device with a lifting motor; the lifting motor rotates to drive the piece-by-piece grabbing device for the stacking mesh to descend, and at the same time, the top rod of the grabbing cylinder pushes down, and the gripping claw is in an open state; during the descent process of the piece-by-piece grabbing device for the stacking mesh, the grabbing heads of each grabbing mechanism are under the action of their own gravity, and the lifting rods are located at the bottom of the guide sleeve, and the lifting nut is located below the photosensitive switch. When the lower end of the grabbing cover of at least one grabbing mechanism contacts the mesh, the horizontal or vertical wires of the mesh are located in the open gripping claws, and the grabbing head of the grabbing mechanism drives the lifting rod to push up, and the lifting nut moves up, triggering the photosensitive switch, and the photosensitive switch transmits the signal to the lifting motor, and the rotation speed of the lifting motor decreases; as the piece-by-piece grabbing device for the stacking mesh slowly descends, the grabbing mechanism that first touches the mesh is on the support of the top mesh The lifting and lowering of the mesh, the grabbing head drives the lifting push rod to continue to move up along the guide sleeve, and the grabbing mechanism that has not touched the mesh moves down with the hanger of the stacking mesh piece-by-piece grabbing device, and the lower end of the grabbing cover of the grabbing mechanism gradually contacts the mesh, and the horizontal or vertical wires of the mesh are located in the opened claws. When the lower ends of the grabbing covers of all the grabbing mechanisms contact the mesh, the photosensitive switch transmits a signal to the lifting motor, the lifting motor stops rotating, and the stacking mesh piece-by-piece grabbing device stops descending; the push rods of all grabbing cylinders retract, and the claws grab the mesh; the lifting motor rotates, driving the stacking mesh piece-by-piece grabbing device to rise, and the first mesh piece located above the stacking mesh is grabbed; the mesh is lifted to the required position by the lifting device; the push rod of the grabbing cylinder pushes down, the claws release, and the mesh falls from the stacking mesh piece-by-piece grabbing device; this reciprocating cycle is repeated until the grabbing of the entire stack of mesh is completed. Advantage 1: Before the lower end of the grabbing cover of the stacked mesh grabbing device reaches the mesh or after the grabbed mesh leaves the whole stack of mesh, under the action of its own gravity, each grabbing mechanism is on the same horizontal plane, which ensures the stability of the equipment and the flatness of the mesh; Advantage 2: During the discharge process of the mesh coming down from the production line, the position of each mesh is not precisely aligned, so the junction of the horizontal wire and the longitudinal wire cannot be well aligned, causing the top mesh to be uneven. When the lower end of the grab cover of a grabbing mechanism touches the mesh, the horizontal wire or the longitudinal wire of the mesh is located in the open claw, and the grab head of the grabbing mechanism drives the lifting rod to push up, and the lifting nut moves up, triggering the photosensitive switch, and the photosensitive switch transmits the signal to the lifting motor, and the rotation speed of the lifting motor decreases; as the grabbing device of the stacked mesh slowly descends piece by piece, the grabbing mechanism that touches the mesh first is supported by the top mesh, and the grab head drives the lifting rod to continue to move up along the guide sleeve The grabbing mechanism that does not touch the mesh moves downward with the hanger of the stacking mesh piece-by-piece grabbing device, and the lower end of the grabbing cover of the grabbing mechanism gradually contacts the mesh, and the horizontal or vertical wires of the mesh are located in the opened claws. When the lower ends of the grabbing covers of all the grabbing mechanisms contact the mesh, the photosensitive switch transmits a signal to the lifting motor, the lifting motor stops rotating, and the stacking mesh piece-by-piece grabbing device stops descending; the top rods of all the grabbing cylinders retract, and the claws grab the mesh. In this way, when the mesh is grabbed, the claws of one or some of the stacking mesh piece-by-piece grabbing devices will not fail to grab the mesh, causing the mesh to slip or tilt during the lifting or moving process, and the mesh can be grabbed more firmly.
[0010] Secondly, since a slide groove is provided on the side of the grabbing cover, an adjusting slide is provided on the outside of the slide groove, and the adjusting slide is fixed to the grabbing cover by an adjusting bolt, before placing the stacking mesh piece by piece grabbing device just above the stacking mesh piece, firstly adjust the distance from the lower end of the adjusting slide to the lower edge of the grabbing cover according to the thickness of the junction of the horizontal wires and the longitudinal wires of the mesh piece, so that the distance from the lower edge of the closed space formed after the gripping claw is gripped to the lower edge of the adjusting slide is slightly larger than the thickness of the junction of the horizontal wires and the longitudinal wires of the mesh piece, and then proceed to the subsequent steps, for different For horizontal or vertical wires of different wire diameters, the thickness of the mesh is different, the wire diameter is different, and the grasping depth of the claw is different. By adjusting the adjusting slide up and down, the distance from the lower edge of the closed space formed by the claw after grasping to the lower edge of the adjusting slide is slightly larger than the thickness of the junction of the horizontal and vertical wires of the mesh. In this way, when the wire diameter is larger, the adjusting slide can be adjusted upward, and when the wire diameter is thin, the adjusting slide can be adjusted downward, which is more convenient to use and is not likely to cause the claw to grasp the lower mesh adjacent to the top mesh, nor is it likely to cause the claw to fail to grasp the top mesh.
[0011] Thirdly, since the hanger includes a transverse hanger rod and multiple longitudinal hangers, a transverse rail is arranged on the transverse hanger rod, and a transverse rail slider with a transverse rail slot is arranged on each longitudinal hanger rod, and the transverse rail is clamped in the transverse rail slot; a longitudinal rail is arranged on the longitudinal hanger rod, and a hanger seat rail slider with a longitudinal rail slot is arranged on the hanger, and the longitudinal rail is clamped in the longitudinal rail slot, and a fastening bolt locked with the hanger seat is arranged on the hanger seat rail slider, the position of the hanger seat on the longitudinal hanger rod and the position of the longitudinal hanger rod on the transverse hanger rod can be adjusted according to the longitudinal and warp wire positions of the mesh, and the adjustment is more convenient.
[0012] Fourthly, since a wire groove is provided on the longitudinal suspension rod and a wire groove card is provided on the outside of the wire groove, the gas line of the grabbing cylinder or the control line of the photosensitive switch can be placed in the wire groove and then pressed down with the wire groove card, thereby preventing the gas line of the cylinder or the control line of the photosensitive switch from coming out of the wire groove.

[0016] The stacking mesh piece-by-piece grabbing device is placed just above the stacking mesh piece by piece by a hoisting device with a lifting motor; the lifting motor rotates to drive the stacking mesh piece-by-piece grabbing device to descend, and at the same time, the top rod 11 of the grabbing cylinder 9 pushes down, and the grabbing claws 13 are in an open state; during the descent process of the stacking mesh piece-by-piece grabbing device, the grabbing heads 7 of each grabbing mechanism 2 are under the action of their own gravity, and the lifting rod 6 is located at the bottom of the guide sleeve 4, and the lifting nut 5 is located below the photosensitive switch 14. When the lower end of the grabbing cover 10 of at least one grabbing mechanism 2 contacts the mesh, the horizontal wire or the longitudinal wire of the mesh is located in the opened claw 13, and the grabbing head 7 of the grabbing mechanism 2 drives the lifting rod 6 to push up, and the lifting nut 5 moves up, triggering the corresponding photosensitive switch 14, and the photosensitive switch 14 transmits a signal to the lifting motor, and the rotation speed of the lifting motor decreases; as the stacking mesh piece-by-piece grabbing device slowly descends, the grabbing mechanism 2 that touches the mesh piece first is at the top Under the lifting of the mesh, the grabbing head 7 drives the lifting rod 6 to continue to move up along the guide sleeve 4, and the grabbing mechanism 2 that has not touched the mesh moves down with the hanger 1 of the stacking mesh piece-by-piece grabbing device, and the lower end of the grabbing cover 10 of the grabbing mechanism 2 gradually contacts the mesh, and the horizontal or vertical wires of the mesh are located in the open claws 13. When the lower ends of the grabbing covers 10 of all the grabbing mechanisms 2 contact the mesh, the photosensitive switch 14 transmits a signal to the lifting motor, and the lifting motor stops. The lifting motor rotates, and the stacking mesh piece-by-piece grasping device stops descending; the top rods 11 of all the grasping cylinders 9 retract, and the claws 13 grasp the mesh; the lifting motor rotates, driving the stacking mesh piece-by-piece grasping device to rise, and the first mesh above the stacking mesh is grasped; the mesh is hoisted to the required position through the lifting device; the top rod of the grasping cylinder pushes down, the claws release, and the mesh falls from the stacking mesh piece-by-piece grasping device; this reciprocating cycle is repeated until the whole stack of mesh is grasped.
[0017] Advantage 1: Before the lower end of the grabbing cover of the stacked mesh grabbing device reaches the mesh or after the grabbed mesh leaves the whole stack of mesh, under the action of its own gravity, each grabbing mechanism is on the same horizontal plane, which ensures the stability of the equipment and the flatness of the mesh; Advantage 2: During the discharge process of the mesh coming down from the production line, the position of each mesh is not precisely aligned, so the junction of the horizontal wire and the longitudinal wire cannot be well aligned, causing the top mesh to be uneven. When the lower end of the grabbing cover 10 of a grabbing mechanism 2 touches the mesh, the horizontal wire or the longitudinal wire of the mesh is located in the open claw 13, and the grabbing head 7 of the grabbing mechanism 2 drives the lifting rod 6 to push up, and the lifting nut 5 moves up, triggering the photosensitive switch 14, and the photosensitive switch 14 transmits the signal to the lifting motor, and the rotation speed of the lifting motor decreases; as the stacking mesh pieces are slowly lowered one by one, the grabbing device that touches the mesh first is lifted by the top mesh, and the grabbing head 7 drives the lifting rod 6 to continue The grabbing mechanism 2 moves upward along the guide sleeve 4, and the grabbing mechanism 2 that does not touch the mesh moves downward with the hanger of the stacked mesh piece-by-piece grabbing device. The lower end of the grabbing cover 10 of the grabbing mechanism gradually contacts the mesh, and the horizontal or vertical wires of the mesh are located in the opened claws. When the lower ends of the grabbing covers of all the grabbing mechanisms contact the mesh, the photosensitive switch transmits a signal to the lifting motor, the lifting motor stops rotating, and the stacked mesh piece-by-piece grabbing device stops descending; the top rods of all the grabbing cylinders retract, and the claws grab the mesh. In this way, when the mesh is grabbed, the claws of one or some of the stacked mesh piece-by-piece grabbing devices will not fail to grab the mesh, causing the mesh to slip or tilt during the lifting or moving process, and the mesh can be grabbed more firmly.
[0018] A slide plate groove 15 is provided on the side of the grab cover 10 , and an adjusting slide plate 16 is provided outside the slide plate groove 15 . The adjusting slide plate 16 is fixed to the grab cover 10 via an adjusting bolt 17 .

For transverse wires or longitudinal wires of different wire diameters, the thickness of the mesh piece is different, the wire diameter is different, and the depth of the gripping claws is different. By adjusting the adjusting slide 16 up and down, the distance from the lower edge of the closed space formed after the gripping claws 13 are engaged to the lower edge of the adjusting slide is slightly larger than the thickness of the junction of the transverse wires and the longitudinal wires of the mesh piece.

When the lower ends of the grabbing covers of all the grabbing mechanisms touch the mesh piece, the photosensitive switch transmits a signal to the lifting motor, the lifting motor stops rotating, and the stacking mesh piece grabbing device stops descending; Step 5: Grab the top mesh The top rods of all grabbing cylinders retract and the claws grab the mesh; Step 6: The stacking mesh piece by piece grabbing device rises The lifting motor rotates, driving the stacking mesh piece-by-piece grabbing device to rise, and the first mesh piece located above the stacking mesh piece is grabbed; Step 7: Move the captured mesh to the required position. Lift the mesh to the required position through the lifting device; Step 8: Put down the mesh The top rod of the grabbing cylinder pushes down, the claws release, and the mesh falls from the stacking mesh piece by piece grabbing device; Step 9: Repeat steps 1 to 8 until the entire stack of mesh is grabbed.
6. The method for hanging and grabbing a mesh according to claim 5, characterized in that: The method further comprises the steps of: Before placing the stacking mesh piece-by-piece grabbing device just above the stacking mesh in the first step, first adjust the distance from the lower end of the adjustment slide to the lower edge of the grabbing cover according to the thickness of the junction of the transverse wires and the longitudinal wires of the mesh, so that the distance from the lower edge of the closed space formed after the gripping claws are engaged to the lower edge of the adjustment slide is slightly larger than the thickness of the junction of the transverse wires and the longitudinal wires of the mesh, and then proceed to the subsequent steps.
