Description

Technical Field

[0001] This invention relates to the field of steel bar conveying technology, specifically to a prestressed positioning mesh long and short bar adjustment conveyor. Background Technology

[0002] During the manufacturing process of box girders, positioning meshes need to be installed in the reinforcing cage for the prestressed ducts. For example... Figure 11 As shown, the positioning mesh is typically formed by two long ribs and several short ribs arranged crosswise at predetermined intervals and welded together. Due to variations in the diameter and position of the prestressed duct, the long and short ribs have different specifications in terms of length and spacing; some long ribs also require bending treatment (e.g., ...). Figure 12 (As shown). Therefore, the feeding, conveying, and positioning processes of long and short ribs are quite complex in the automated production of positioning mesh.

[0003] In existing technologies, multiple conveying mechanisms are often used to transport long and short ribs separately, and robotic arms or dedicated gripping mechanisms are used to pick up, place, and position the short ribs to achieve their cross-arrangement with the long ribs. While this approach can achieve automated production, it generally suffers from the following problems: First, the robotic arms or gripping mechanisms have complex structures and require sophisticated control systems, resulting in high equipment costs and difficult maintenance. Second, the multi-station gripping and positioning process requires high synchronization control, which can easily affect overall production efficiency and finished product quality due to mismatched cycle times or positioning errors.

[0004] In addition, some existing solutions constrain and position the reinforcing bars by setting up complex positioning structures or guiding mechanisms, but this usually requires coordination at multiple points or repeated positioning processes, which not only increases the complexity of the structure, but also makes it inconvenient to adjust when switching between different specifications of mesh, making it difficult to balance versatility and stability.

[0005] Therefore, how to achieve automatic conveying, posture adjustment and welding positioning of long and short ribs while reducing the need for robotic arms or complex control structures, and improve the overall stability and adaptability of the system, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] This invention provides a prestressed positioning mesh long and short rib adjustment conveyor, including a transverse guiding structure, a longitudinal guiding structure, a longitudinal guiding zone, a switching mechanism, a pushing mechanism, a limiting guide bracket, a displacement conveying mechanism, a second longitudinal limiting component, a first longitudinal limiting component, and a centering component. The transverse guiding structure is used to convey long and short ribs and has a separating port to separate the short ribs; the longitudinal guiding structure is used to guide the short ribs into the welding station; the longitudinal guiding zone is arranged horizontally in parallel and is used to receive the long ribs output from the transverse guiding structure; the switching mechanism is used to guide the sequentially output long ribs into different longitudinal guiding zones, so that the long ribs are arranged in a parallel manner; the pushing mechanism is used to push the long ribs in the longitudinal guiding zone to the welding station; the limiting guide bracket is correspondingly arranged with the longitudinal guiding zone and is located between the welding station and the longitudinal guiding zone, used to guide and limit the long ribs and adjust the spacing between them; the displacement conveying mechanism is used to receive the separated short ribs and switch them from longitudinal conveying state. After being conveyed laterally, it is fed to the longitudinal guiding structure. Longitudinal limiting component 2 and longitudinal limiting component 1 are set on the welding station. Longitudinal limiting component 1 switches between a limiting position and an avoidance position. When it is in the limiting position, it cooperates with longitudinal limiting component 2 to form a longitudinal limiting space for accommodating short ribs. When it is in the avoidance position, it avoids the conveying path of long ribs to release the welded mesh portion. The centering component is used to center and limit the short ribs laterally. After being pushed, the ends of the long ribs pass through longitudinal limiting component 2 and abut against longitudinal limiting component 1 to form a positioning reference. The short ribs are guided by the longitudinal guiding structure and fall into the longitudinal limiting space, completing the longitudinal positioning and spanning the parallel long ribs.

[0007] In one possible implementation, the long ribs output by the transverse guiding structure fall directly into one of the longitudinal guiding zones. The switching mechanism includes a rotating shaft and several transverse stops with receiving grooves. The transverse stops are distributed longitudinally on the rotating shaft and lie horizontally on the longitudinal guiding zone that directly receives the long ribs as the rotating shaft rotates, so as to receive the long ribs. The rotating shaft rotates in the opposite direction to make the long ribs fall into another longitudinal guiding zone.

[0008] In one possible implementation, the longitudinal guiding zone includes a plurality of rollers and a flared limiting guide opening, the rollers being evenly distributed along the longitudinal direction to form a receiving zone, and the limiting guide opening being located on the receiving zone.

[0009] In one possible implementation, the limiting guide bracket includes a frame with at least two limiting slots, which are distributed longitudinally to form limiting points for limiting the long ribs in the lateral direction and guiding the long ribs in the longitudinal direction.

[0010] In one possible implementation, the longitudinal guide structure is provided with a feeding groove wheel, and the feeding groove wheel has several feeding slots evenly distributed in the circumferential direction. The short ribs roll down along the longitudinal guide structure to the feeding groove wheel. As the feeding groove wheel rotates, the short ribs enter the feeding slots and are released when the feeding slots rotate to the other side. Then, they continue to roll down along the longitudinal guide structure into the longitudinal limiting space.

[0011] In one possible implementation, the displacement conveying mechanism includes: a longitudinal conveying section located below the feed inlet for receiving and longitudinally conveying the falling short ribs; a transverse conveying section located at the end of the longitudinal conveying section for transversely conveying the short ribs to the feed end of the longitudinal guide structure; a rotatably mounted clamping head located at the intersection of the extended conveying paths of the transverse and longitudinal conveying sections, which clamps the short ribs on the longitudinal conveying section and rotates them 90 degrees to transfer them to the transverse conveying section, thus completing the posture change of the short ribs; and a pushing head for pushing the short ribs on the transverse conveying section into the longitudinal guide structure.

[0012] In one possible implementation, the clamping head includes a mounting base and symmetrically arranged grippers, the grippers being provided with arcuate grooves.

[0013] In one possible implementation, a bending mechanism is provided between the longitudinal material guiding area and the welding station, which can bend the long ribs on the limiting guide bracket.

[0014] In one possible implementation, the bending mechanism includes a first mold located in the middle and second molds located on both sides, wherein the second molds on both sides bend two long ribs on the parallel limiting guide bracket by closing with the first mold in the middle.

[0015] In one possible implementation, the longitudinal limiter is laterally movable.

[0016] The above-mentioned one or more technical solutions in the embodiments of the present invention have the following technical effects: According to the embodiments of the present invention, a prestressed positioning mesh long and short rib adjustment conveyor achieves automatic diversion of long and short ribs through a transverse guiding structure with a material distribution port, and completes the posture conversion of short ribs through a displacement conveying mechanism; further, combined with a longitudinal guiding structure and longitudinal limiting components one and two, the short ribs directly enter the longitudinal limiting space formed by the longitudinal limiting components one and two under the action of gravity, while simultaneously forming a positioning reference with the end of the long rib, completing the positioning and placement of the long and short ribs. This structure uses gravity guidance and limiting cooperation to replace the traditional gripping and positioning method, and the overall structure is simple and compact, significantly reducing equipment complexity and control difficulty, and enabling stable and reliable fully automated production, while also meeting the production needs of positioning meshes of different specifications within a certain range. It has the advantages of compact structure, high degree of automation, and strong adaptability. Attached Figure Description

[0030] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Please see Figures 1-12 A prestressed positioning mesh length and short rib adjustment conveyor includes a transverse guiding structure 2, a longitudinal guiding structure 7, two transversely parallel longitudinal guiding zones 4, two transversely parallel limiting guide brackets 5, a pushing mechanism 6, a switching mechanism 3, and a displacement conveying mechanism 8. Both the transverse guiding structure 2 and the longitudinal guiding structure 7 are inclined, and the transverse guiding structure 2 is provided with a distributing port 1. It should be noted that in the accompanying drawings of this embodiment, the forward and backward direction indicated by the arrows is the transverse direction, and the left and right direction is the longitudinal direction.

[0032] like Figure 1As shown, the transverse guide structure 2 slopes from back to front and from top to bottom. Both long ribs 100 and short ribs 200 are fed longitudinally, alternating in a cyclical manner with two long ribs 100 followed by several short ribs 200. The number of short ribs 200 is determined by the number of short ribs 200 on a single positioning mesh piece. After feeding, the long ribs 100 and short ribs 200 roll downwards along the transverse guide structure 2. During this process, the short ribs 200 are separated when passing through the separating port 1, while the long ribs 100 continue rolling downwards through the separating port 1. This scheme is simple in structure and facilitates the separation of long ribs 100 and short ribs 200. The automated positioning mesh production line only requires one straightening and cutting device, effectively reducing the floor space and production costs compared to an automated positioning mesh production line using two straightening and cutting devices.

[0033] Combination Figure 1 and Figure 3 As shown, the parallel longitudinal guide zones 4 are located at the lower front end of the transverse guide structure 2. After rolling down the transverse guide structure 2, the long ribs 100 fall directly into the rear longitudinal guide zone 4. A switching mechanism 3 is located between the parallel longitudinal guide zones 4. When one long rib 100 falls into the rear longitudinal guide zone 4, the switching mechanism 3 sends the next long rib 100 into the front longitudinal guide zone 4. At this time, the two long ribs 100 are located in the longitudinal guide zones 4, arranged in a parallel configuration.

[0034] The limiting guide brackets 5 are configured one-to-one with the longitudinal material guiding areas 4, and are located between the welding station and the longitudinal material guiding areas 4. Specifically, two laterally parallel limiting guide brackets 5 are respectively positioned at the left end of their respective longitudinal material guiding areas 4. The rear limiting guide bracket 5 can be moved back and forth for position adjustment, and this adjustment is achieved by a servo motor driving a ball screw. Initially, the distance between the two limiting guide brackets 5 is the same as the distance between the two longitudinal material guiding areas 4. When the two long ribs 100 are located in the longitudinal material guiding areas 4, the pushing mechanism 6 pushes these two long ribs 100 from right to left, causing them to enter their respective limiting guide brackets 5 until the left end of the long rib 100 reaches the welding station, where a welding table 15 is located. At this point, the long rib 100 will have completely left the longitudinal material guiding area 4. Afterwards, the distance between the two parallel long ribs 100 can be adjusted by adjusting the position of the limiting guide brackets 5 in the back-and-forth direction. Position the long rib 100 in the position to be welded.

[0035] The displacement conveyor mechanism 8 is located below the feed inlet 1. For example... Figure 4As shown, the displacement conveying mechanism 8 includes a longitudinal conveying section 81, a transverse conveying section 82, a clamping head 83, and a pushing head 84. The longitudinal conveying section 81 is located below the feed inlet 1, and the short ribs 200 fall directly onto the longitudinal conveying section 81 after being separated from the feed inlet 1. The transverse conveying section 82 is located at the left end of the longitudinal conveying section 81, and the two are perpendicularly distributed. The clamping head 83 is located at the intersection of the extended conveying paths of the transverse conveying section 82 and the longitudinal conveying section 81. The clamping head 83 clamps the short ribs 200 on the longitudinal conveying section 81 and rotates them 90 degrees onto the transverse conveying section 82, and then releases them, allowing the short ribs 200 to fall onto the transverse conveying section 82, thus completing the displacement conveying of the short ribs 200. Both the longitudinal conveying section 81 and the transverse conveying section 82 are conveyor belts, and intermittently arranged limiting baffles are fixedly installed on the frames on both sides of the conveyor belts to prevent the short ribs 200 from falling laterally during conveying. In addition, a material guide section (not shown in the figure) is provided below the material distribution port 1 to guide the falling short ribs 200 and make them fall stably onto the longitudinal conveying section 82.

[0036] The longitudinal guide structure 7 is located to the left of the limiting guide bracket 5 and is opposite to the limiting guide bracket 5, with the welding area located between them. The longitudinal guide structure 7 slopes from left to right and from top to bottom, with its upper left end located to the right of the transverse conveying section 82, and the pusher head 84 located to the left of the transverse conveying section 82. When the short rib 200 is conveyed to the longitudinal guide structure 7 by the transverse conveying section 82, the pusher head 84 pushes it to the right, causing the short rib 200 to fall into the longitudinal guide structure 7 and roll down along the longitudinal guide structure 7 to the welding station. The clamping head 83 includes a mounting base 831 and symmetrically arranged clamps 832, with arc-shaped grooves 833 on the clamps 832. Figure 2 As shown, symmetrical grippers 832 are mounted on mounting base 831, which is rotatably mounted between transverse conveying section 82 and longitudinal conveying section 81.

[0037] The welding station is equipped with a longitudinal limiting component 9, a longitudinal limiting component 10, and a centering component 11. The longitudinal limiting component 9 is located to the left of the longitudinal limiting component 10 (e.g., ...). Figure 4 As shown in the figure, it is connected to the lower port of the longitudinal material guiding structure 7.

[0038] Among them, the longitudinal limiting component 2 10 consists of two limiting posts fixedly installed on the welding table 15 (such as...). Figure 6 As shown), the limiting posts are arranged side by side. The longitudinal limiting component 9 consists of two limiting blocks arranged side by side and moving relative to each other. The two limiting blocks are set to move back and forth (i.e., to move laterally), and switch between the limiting position and the avoidance position by moving in the back and forth direction. The limiting position includes the initial limiting position and the continuous processing limiting position.

[0039] like Figure 6As shown in the upper left view, with the limiting blocks in their initial limiting position, the left ends of the parallel long ribs 100 abut against their respective limiting blocks. That is, when the long ribs 100 are pushed to the welding station by the pushing mechanism 6, the long ribs 100 first pass through the limiting posts until their left ends abut against the limiting blocks, at which point the pushing stops. At this time, the limiting space between the two parallel limiting blocks and the two parallel limiting posts is the longitudinal limiting space.

[0040] When the short rib 200 rolls down the longitudinal guide structure 7 to the welding station, it will directly roll into the longitudinal limiting space, completing the longitudinal positioning, and simultaneously straddle the two parallel long ribs 100. Subsequently, the centering component 11 laterally centers and limits the short rib 200, placing it in a preset relative position with the parallel long ribs 100. Finally, the two can be pressed together and welded using resistance welding equipment. It should be noted that after the long ribs 100 stop pushing, the spacing can be adjusted using the limiting guide bracket 5 to ensure the parallel long ribs 100 are at a preset distance before the short rib 200 rolls down. The centering component 11 is a linear module with two movable push heads. The linear module controls the movement of the two movable push heads to laterally limit the short rib 200, placing it in a preset lateral position relative to the long ribs 100.

[0041] After welding, the two parallel limiting blocks move in opposite directions to avoid the conveying path of the long rib 100, as shown. Figure 6 As shown in the upper right view, at this point, the two limiting blocks are in the clearance position, and the long rib 100 can move to the left so that the mesh portion formed after the short rib 200 is welded to the long rib 100 can move to the left and leave the welding station. When the next welding point of the long rib 100 enters the welding station, the movement stops. Then, the two limiting blocks move relative to each other until they abut against the long rib 100 on the corresponding side, as shown in the upper right view. Figure 6 As shown in the lower center view, the limiting block is currently in the continuous processing limiting position. The limiting block and the parallel limiting posts cooperate to form a longitudinal limiting space to accommodate the next rolling short rib 200 and to complete its longitudinal positioning. Then, the aforementioned lateral centering limiting, welding, and leftward movement of the welded mesh portion continue. The limiting block repeatedly switches between the continuous processing limiting position and the avoidance position until the entire positioning mesh is welded. This process is then repeated to achieve automated production of batch positioning meshes. The movement of the aforementioned limiting block can be driven by a cylinder, and high-precision movement positioning is not required. The initial limiting position only needs to limit the end of the long rib 100. In the continuous processing limiting position, the limiting block moves until it abuts against the corresponding side of the long rib 100.

[0042] When the spacing of the short ribs 200 changes, the leftward shift of the mesh portion after welding can be controlled to adapt. When the spacing of the long ribs 100 changes, the relative and opposite movement distances of the parallel limiting blocks can be controlled to meet the longitudinal positioning of the short ribs 200 and the end limiting requirements of the long ribs 100.

[0043] In summary, this invention enables automated production of positioning mesh without the need for robotic arms or specialized gripping mechanisms, nor complex positioning or guiding mechanisms. It achieves automatic diversion, conveying, and positioning of long ribs 100 and short ribs 200. The entire process is compact and reliably operates in a fully automated, integrated manner, while also meeting the production requirements of positioning mesh of different specifications. Furthermore, only one straightening and cutting device is needed, resulting in a small footprint and a simple control system for the entire automated positioning mesh production system. It can stably, reliably, and efficiently meet the fully automated production needs of mesh of different specifications.

[0044] See Figure 1 , Figure 3 , Figure 7 and Figure 8 The switching mechanism 3 includes a rotating shaft 31 and several horizontal baffles 33 with receiving grooves 32. The rotating shaft 31 is rotatably mounted between parallel longitudinal guide zones 4, and the horizontal baffles 33 are distributed longitudinally on the rotating shaft 31. Figure 7 As shown, when the horizontal stop 33 is in a vertical state, the long rib 100 output by the transverse guiding structure 2 falls directly into the rear longitudinal guiding area 4; when the horizontal stop 33 rotates with the rotating shaft 31 and lies horizontally on the rear longitudinal guiding area 4, as... Figure 8 As shown, the long rib 100 output by the transverse guiding structure 2 will fall into the receiving groove 32 on the transverse stop 33. Then, when the rotating shaft 31 rotates in the opposite direction until the receiving groove 32 is vertical or tilted downward, the long rib 100 will fall into the longitudinal guiding area 4 on the front side under the action of gravity.

[0045] See Figure 2 , Figure 5 and Figure 7 The longitudinal guiding zone 4 includes several rollers 41 and a trumpet-shaped limiting guide opening 42. The rollers 41 are evenly distributed along the longitudinal direction to form a receiving zone, and the limiting guide opening 42 is located on the receiving zone. When the long rib 100 output by the transverse guiding structure 2 falls, it will fall into the receiving zone under the limiting guidance of the limiting guide opening 42.

[0046] See Figure 1 , Figure 5 and Figure 9 A bending mechanism 12 is provided between the longitudinal material guiding area 4 and the welding station. The limiting guide bracket 5 includes a frame 52 with two limiting slots 51. An extension frame 53 is fixedly connected to the left side of the frame 52, and a support block 54 (such as...) is fixedly installed on the extension frame 53. Figure 9As shown), the limiting slots 51 are distributed longitudinally and form two limiting points, limiting the long rib 100 laterally, guiding the long rib 100 longitudinally, and supporting the long rib 100 vertically. The support block 54 supports the long rib 100. The bending mechanism 12 is located between the support block 54 and the frame 52, and the bending mechanism 12 is raised and lowered. When the long rib 100 needs to be bent, the bending mechanism 12 rises to the bending position, at which time the long rib 100 on the limiting guide bracket 5 can be bent directly. When the long rib 100 does not need to be bent, the bending mechanism 12 descends away from the bending position. Figure 9 As shown, the bending mechanism 12 includes a lifting seat 123 with a first mold 121 and a second mold 122. The second mold 122 are symmetrically distributed front and back and are slidably mounted on the lifting seat 123. The first mold 121 is fixedly mounted on the lifting seat 123 and located between the symmetrical second molds 122. The second molds 122 on both sides move towards the middle to close with the first mold 121, thereby bending the two long ribs 100 on the parallel limiting guide bracket 5.

[0047] It should be noted that, in order to facilitate the smooth entry of the long rib 100 into the limiting guide bracket 5, a lifting structure can be installed under the limiting guide bracket 5. After the long rib 100 is initially pushed into the receiving area of ​​the limiting guide bracket 5, the lifting structure controls the limiting guide bracket 5 to rise to the preset position. During this process, the long rib 100 can smoothly enter the limiting slot 51, realizing the support, limiting and guiding of the long rib 100. Then, the long rib 100 continues to be pushed until it is pushed into place.

[0048] See Figure 1 , Figure 4 and Figure 10 The longitudinal material guiding structure 7 is equipped with a feeding groove wheel 13 and a rotating shaft, such as Figure 10 As shown, a number of feeding groove wheels 13 are evenly installed on the rotating shaft from front to back, and a number of feeding grooves 14 are evenly distributed around the circumference of the feeding groove wheels 13 (e.g., ...). Figure 10 As shown), the short rib 200 rolls down along the longitudinal guide structure 7 to the feeding groove wheel 13. The feeding groove wheel 13 rotates with the shaft, and the short rib 200 enters the feeding groove 14 and is released when the feeding groove 14 rotates to the other side. Then it continues to roll down along the longitudinal guide structure 7 into the longitudinal limiting space.
