Description

Technical Field

[0001] This invention relates to the field of steel mesh processing, and in particular to a square steel mesh transport and stacking device and control method. Background Technology

[0002] In existing technologies, automatic stacking of steel mesh is achieved through a first and second gripper positioned above a transport track. The first gripper moves in both horizontal and vertical directions; the second gripper, in addition to moving in both directions, also needs a flipping function. For stacking stability and space efficiency, adjacent steel meshes are arranged in opposite directions. In a typical process, the second gripper extends downwards to grab the steel mesh on the track, then rises and flips the mesh so that it faces upwards; the first gripper moves above the second gripper, grabs the mesh, and places it in a specific area; during the placement of the next mesh, the first gripper directly grabs the mesh from the pipe and places it in a specific area. Several problems exist with this existing technology: when the steel mesh processing speed is too fast, the flipping and stacking speed is difficult to match; the transport and flipping process of the steel mesh occupies a large amount of space and can easily create safety hazards. Currently, most steel mesh products on the market require a square shape. Summary of the Invention

[0019] The transfer component is controlled to drive the rotating component from the stacking position to the initial position.

[0020] Furthermore, a baffle structure matching the preset position is provided at the end of the transport component along its length.

[0037] Reference Figures 1 to 9 In one embodiment of the present invention, a square steel mesh transport and stacking device, matched with a square steel mesh processing device, includes:

[0038] The transport component 200 is used to transfer the square steel mesh 100 to a preset position, wherein the preset position is a square corresponding to the square steel mesh 100, the center of the preset position is the position center, and the diameter of the reinforcing bar of the square steel mesh 100 is A;

[0039] The rotating assembly 300 includes a first driving part 310, a second driving part 320, and a rotating shaft 330. The first driving part 310 is used to drive the rotating shaft 330 to move in the vertical direction, and the second driving part 320 is used to drive the rotating shaft 330 to rotate in the horizontal direction. The lower end of the rotating shaft 330 is connected to a pick-and-place part 340.

[0040] The transfer component 400 is used to drive the rotating component 300 to move in at least one dimension on the horizontal plane. The transfer component 400 is provided with an initial position corresponding to the preset position and a stacking position corresponding to the square steel mesh 100. When the rotating component 300 is located at the initial position, the projection position of the rotating shaft 330 on the preset position is the rotation center. There is an offset distance between the rotation center and the position center. The offset distance is A and is perpendicular to the side of the preset position.

[0041] A controller is used to control the operation of the transfer component 400 and the rotation component 300.

[0042] In existing technologies, automatic stacking of steel mesh is achieved through a first and second gripper positioned above a transport track. The first gripper moves in both horizontal and vertical directions; the second gripper, in addition to moving in both directions, also needs a flipping function. For stacking stability and space utilization efficiency, adjacent steel meshes are arranged in opposite directions. In a typical process, the second gripper extends downwards to grab the steel mesh on the track, then rises and flips the mesh so that it faces upwards; the first gripper moves above the second gripper, grabs the mesh, and places it in a specific area; during the placement of the next mesh, the first gripper directly grabs the mesh from the pipe and places it in a specific area. Several problems exist with this existing technology: when the steel mesh processing speed is too fast, the flipping and stacking speed is difficult to match; the transport and flipping processes of the steel mesh occupy a large amount of space and can easily create safety hazards.

[0043] Reference Figure 1-3 For a stack of 100 square steel meshes, there are actually only two possible positional states: all upright square steel meshes 100 are aligned, and all reversed square steel meshes 100 are aligned, with a misalignment between adjacent upright and reversed square steel meshes 100. For a uniformly arranged square steel mesh 100, rotating it 90 degrees on a plane achieves the same effect as flipping it over. Combining this with the offset distance between the rotation center and the position center, misalignment is achieved. Figure 1 and 2 In the diagram, the circular marker indicates the center of rotation. Figure 1In the middle, the transfer component 400 moves the first square steel mesh 100 from the preset position to the stacking position (where the dotted line represents the position before transfer); in Figure 2 In the process of stacking, the first square steel mesh 100 is rotated 90 degrees around the rotation center before stacking, thus creating a misalignment (the dotted line represents the area before rotation). During the stacking process, since the second square steel mesh 100 has already formed a misalignment with the first square steel mesh 100, a tight stacking can be achieved (the dotted line represents the area before transfer).

[0044] In this invention, the above-mentioned rotational characteristics simplify and increase the efficiency of the square steel mesh transport and stacking device, while minimizing the vertical space required. During the use of the overall square steel mesh transport and stacking device, the square steel mesh 100 produced by the square steel mesh processing device needs to be automatically transferred to the stacking position to achieve the stacking effect. Specifically, the transfer component 400 only needs to achieve one-dimensional linear movement (from the initial position to the stacking position), which can be achieved through a motor, hydraulic pressure, or pneumatic pressure. The transfer component 400 can be fixed to an external base structure or have a matching support.

[0045] When the square steel mesh 100 is transported to the preset position by the transport component 200, the rotating component 300, in its initial position, drives the rotating shaft 330 downward via the first drive unit 310. At this time, the pick-and-place unit 340 can pick up the square steel mesh 100. Then, the second drive unit 320 can select whether to drive the rotating shaft 330 to rotate 90 degrees according to a pattern, and the transfer component 400 moves the rotating component 300 from the preset position to the stacking position. The first drive unit 310 drives the rotating shaft 330 to move vertically, thereby completing the stacking function. After the pick-and-place unit 340 picks up the square steel mesh 100, the rotation, horizontal movement, and vertical movement can be performed simultaneously, thereby improving the overall operating efficiency. In the above process, the time and position selection for picking and placing can be preset in the controller. If the controller is a PLC type, it can also be done through intelligent recognition. In this case, the controller needs to include structures such as vision sensors to achieve intelligent control. During the transfer of two adjacent square steel meshes 100, the rotating component 300 grips and places the square steel meshes 100 in the same position. By utilizing the characteristic of rotating the square steel meshes 100 at intervals, the staggered placement of adjacent square steel meshes 100 can be achieved. The gripping and placing method of the pick-and-place unit 340 can be clamping or magnetic attraction, etc. The direction of the rotation center deviating from the position center can be any one of the four sides of the preset position. The difference in the direction of deviation will only change the stacking pattern of the square steel meshes 100 at the stacking position.

[0046] Taking the preset time and position for grabbing and placing the square steel mesh 100 as an example, firstly, one of the two adjacent square steel meshes 100 is set to rotate 90 degrees to achieve a stacking effect; after a certain time interval, the square steel mesh 100 reaches the preset position. After the rotating component 300 grabs the square steel mesh 100, the transfer component 400 drives the rotating component 300 from the initial position to the stacking position. The rotating component 300 can be driven back to the initial position after putting down the square steel mesh 100. The rotation operation of the square steel mesh 100 can be carried out synchronously from the initial position to the stacking position.

[0047] It should be noted that when the shape of the steel mesh is no longer required to be square, the rotating component 300 and the transfer component 400 can function as the first gripper described above in the prior art.

[0048] Reference Figure 1-8 In one embodiment, the transport component 200 is provided with a baffle structure 600 matching the preset position at its end along its length, and the rotating component 300 is provided corresponding to the baffle structure 600.

[0049] Through the aforementioned baffle structure 600, the square steel mesh 100 is conveyed to this position by the transport component 200. The square steel mesh 100 is constrained by the baffle structure 600, thus ensuring accurate positioning. At this point, the rotating component 300's gripping position of the square steel mesh 100 is also accurate, improving the accuracy of the transport process. The baffle structure 600 can be one or more baffles corresponding to the transport component 200. Therefore, when the square steel mesh 100 is conveyed to the baffle, its position is defined.

[0050] In one embodiment, a magnetic fixing device is provided corresponding to the baffle structure 600, which is used to attract and fix the square steel mesh 100 located at the baffle structure 600.

[0051] The magnetic fixing device described above can be a permanent magnet or an electromagnet. When it is an electromagnet, the operation of the magnetic fixing device can be coordinated with the rotating component 300 (the electromagnet is de-energized when the rotating component 300 grips); when it is a permanent magnet, the gripping force of the rotating component 300 needs to be greater than the attraction force of the magnetic fixing device. The magnetic fixing device can assist the baffle structure 600 in further limiting the positional changes of the square steel mesh 100, thereby ensuring the accurate operation of the rotating component 300.

[0052] Reference Figure 1-8 In one embodiment, the transport assembly 200 includes a plurality of powered transport rollers 210 arranged in an array.

[0053] In most cases, the power conveyor rollers 210 are made of metal, which reduces the possibility of damage to the square steel mesh 100 during transport. The gaps between the power conveyor rollers 210 can be utilized by the square steel mesh transport stacking device (for example, some auxiliary structures can be set below the power conveyor rollers 210, and the auxiliary structures can extend and retract vertically within the gaps between the power conveyor rollers 210).

[0054] Reference Figure 9 In one embodiment, the square steel mesh transport stacking device further includes a guide device 500 that matches the transport assembly 200. The guide device 500 includes two side guide structures 510 that extend from below the transport assembly 200 to below the transport assembly 200.

[0055] The guide device 500 ensures more accurate positioning of the square steel mesh 100 on the transport assembly 200, which is beneficial for the operation of the rotating assembly 300. Its lower placement saves space and frees up space above the transport assembly 200. In this embodiment, the guide device 500 is fixed to the base of the powered transport roller 210.

[0056] In one embodiment, the dimensions of the two lateral guide structures 510 are adjustable in the width direction of the transport assembly 200.

[0057] The adjustable features of the two side guide structures 510 allow for the adaptation of square steel mesh 100 of different sizes. The width between the side guide structures 510 can be adjusted manually or electrically.

[0058] In one embodiment, the pick-and-place part 340 is a plate-shaped electromagnet.

[0059] Therefore, for square steel meshes 100 of different sizes, there is no need to specifically adjust the pick-and-place section 340, as the plate-shaped electromagnets can all be matched. Specifically, during the operation, when the square steel mesh 100 is rotated to the preset position, the rotating component 300 in the initial position drives the rotating shaft 330 downward through the first drive section 310. At this time, the electromagnet is energized to pick up the square steel mesh 100. After the transfer component 400 moves the rotating component 300 from the preset position to the stacking position, the rotating shaft 330 is driven to move vertically through the first drive section 310. At this time, the electromagnet is de-energized and the square steel mesh 100 is lowered.

[0060] In one embodiment, the offset distance is parallel to the length direction of the transport component 200.

[0061] Generally, the center of the square steel mesh 100 coincides with the center of the transport component 200, meaning that the preset position cannot be moved perpendicular to the length of the transport component 200. If the offset distance were perpendicular to the length of the transport component 200, then for square steel meshes 100 of different sizes, the preset position of the transfer component 400 would need to be adjusted in the direction perpendicular to the length of the transport component 200 to satisfy the offset distance dimension A. However, in this embodiment, the offset distance is parallel to the length of the transport component 200. Therefore, for square steel meshes 100 of different sizes, only the preset position on the transport component 200 needs to be adjusted in the direction parallel to the length of the transport component 200, eliminating the need to adjust the transfer component 400. For example, if the preset position is achieved through some positioning structure (the square steel mesh 100 is restricted when it moves to the positioning structure), then the adjustment of the preset position in the direction parallel to the length of the transport component 200 can be achieved by adjusting the positioning structure.

[0062] The present invention also provides a control method for the above-mentioned square steel mesh transport and stacking device, comprising the following steps:

[0063] Determine whether the square steel mesh 100 has reached the preset position;

[0064] If so, the first drive unit 310 is controlled to drive the rotating shaft 330 toward the square steel mesh 100, and the pick-and-place unit 340 is controlled to grab the square steel mesh 100.

[0065] The transfer component 400 is controlled to drive the rotating component 300 from the initial position to the stacking position, and the second driving unit 320 is controlled to perform a 90-degree rotation operation on the square steel mesh 100 according to a preset rule, wherein the preset rule is to perform a 90-degree rotation operation every other time.

[0066] The first drive unit 310 is controlled to drive the rotating shaft 330 to complete the stacking operation;

[0067] The transfer component 400 is controlled to drive the rotation component 300 from the stacking position to the initial position.

[0068] Through the above control method, a square steel mesh transport and stacking device is realized efficiently and simply. The controller determines whether the square steel mesh 100 has been transported to the preset position by the transport component 200 (the above determination can be sensor-based or time-based, etc.); the rotating component 300, which is in the initial position, is driven by the first drive unit 310 to move the rotating shaft 330 downward, at which time the pick-and-place unit 340 can pick up the square steel mesh 100; then, according to the pattern, the second drive unit 320 can be selected to drive the rotating shaft 330 to rotate 90 degrees; the transfer component 400 moves the rotating component 300 from the preset position to the stacking position; the first drive unit 310 drives the rotating shaft 330 to move in the vertical direction, thereby completing the stacking function.

[0069] In one embodiment, the transport component 200 has a baffle structure 600 at its end along its length that matches the preset position 5. The controller includes an image sensing system, which is used to determine whether the square steel mesh 100 is in motion. The step of determining whether the square steel mesh 100 has reached the preset position includes:

[0070] Acquire the sensing information of the image sensing system;

[0071] The sensor information is used to determine whether the square steel mesh 100 has reached the preset position.

[0072] 0 In this embodiment, an efficient and simple method is provided to determine whether the square steel mesh 100 is

[0073] Reaching the preset position. Specifically, when the square steel mesh 100 is blocked by the baffle structure 600, it means that the preset position has been reached. At this time, the square steel mesh 100 stops moving, and the image sensing system obtains the above state that the square steel mesh 100 stops moving and transmits the sensing information to the controller.

[0074] In summary, the square steel mesh transport and stacking device and control method provided by this invention simplify and improve the efficiency of the square steel mesh transport and stacking device through the rotation 5 characteristic, and also address the issue of vertical space...

[0075] It occupies less space; during the use of the overall square steel mesh transport and stacking device, the square steel mesh 100 produced by the square steel mesh processing device needs to be automatically transferred to the stacking position to achieve the stacking effect.

[0076] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention.

[0077] Any equivalent structural or procedural transformations made using the description and drawings of this invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this invention.
