Description

Technical Field

[0001] This invention belongs to the technical field of steel bar welding equipment, specifically relating to an automatic feeding device for horizontal short steel bars in metal mesh. Background Technology

[0002] Welded steel mesh (also known as steel wire mesh) is a mesh-like material made by resistance welding cold-rolled ribbed or smooth steel bars at all intersections. It is mostly used for reinforcement in concrete structures.

[0003] When used as reinforcement, the structural layout of the building structure must be considered, such as the location of doors, windows, or other reserved openings. The reinforcement needs to be structurally designed to avoid these openings and allow for installation space. The conventional production method is to directly use steel bars of the required length to be distributed in a crisscross pattern and welded into a mesh. Then, the reserved openings are cut into the mesh according to the dimensions and positions. Although this welding method can meet the needs of product production, it involves many steps, and the scrap material from the cutting process generally cannot be directly used in other fields, resulting in material waste and greatly limiting the reduction of the cost of the metal mesh.

[0004] Later, someone proposed to first weld steel bars of the same length (generally called long bars), and then weld steel bars at the reserved opening (generally called short bars). The steel bars along the direction of the metal mesh conveying are called longitudinal bars, and the steel bars perpendicular to the direction of the metal mesh conveying are called transverse bars. Although this welding method reduces the generation of waste material, it still has many problems, such as many welding processes, large area, and cumbersome workpiece turnover. Therefore, it is urgent to improve the existing technology to solve the above problems that restrict production. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic feeding device for horizontal short ribs of metal mesh, so as to reduce the large footprint and numerous processes required for metal mesh welding.

[0006] To achieve the above objectives, embodiments of the present invention provide an automatic feeding device for horizontal short reinforcing bars of metal mesh, used to transport horizontal short reinforcing bars to a welding unit. The welding unit includes a lower welding seat and an upper welding seat that is lifted and disposed above the lower welding seat, comprising: The platform is erected above the upper welding seat; A storage rack is located on the side of the platform. The storage rack has a storage space that runs vertically through the platform. The upper and lower ends of the storage space have a feeding port and a discharging port, respectively. The material feeding unit includes a transfer shaft, a clamping assembly, and a horizontal guide frame. The transfer shaft is rotatably mounted at the lower end of the storage rack and located below the discharge port. There are two sets of clamping assemblies, each set of which is sleeved on the outer periphery of the transfer shaft. The peripheral wall of each clamping assembly has a groove for receiving the transverse short ribs that fall from the discharge port. The clamping assembly can drive the transverse short ribs to swing downward under the rotation of the transfer shaft. The horizontal guide frame is slidably mounted on one side of the lower welding seat to receive the transverse short ribs that fall from the clamping assembly and guide the transverse short ribs to roll down to the top of the longitudinal ribs on the lower welding seat.

[0007] In one possible implementation, the lower end of the storage rack is provided with an outer guide plate surrounding the outer periphery of the transfer shaft. The outer guide plate is used to cooperate with the clamping assembly to form a transition space for the transfer cross rib to limit the movement path of the cross rib.

[0008] In one possible implementation, each set of clamping components includes two clamping rings rotatably sleeved on the transfer shaft. Each clamping ring is locked to the transfer shaft by a locking member. Each clamping ring has a slot on its outer periphery. The two slots can form a through-hole clamping space for clamping the transverse short ribs after the two clamping rings rotate relative to each other.

[0009] One possible implementation also includes: A material platform is slidably disposed on the platform along the axial direction of the transverse short ribs. The material platform is provided with several spaced uprights for supporting the transverse short ribs. A swing frame is oscillating on the platform and located between the material platform and the storage rack; A magnetic strip is provided at the swing end of the swing frame. The magnetic strip can attract the horizontal short ribs on the upright frame and dislodge the horizontal short ribs to the feeding port of the storage rack under the swing action of the swing frame.

[0010] One possible implementation also includes: The telescopic component has a magnetic strip disposed at its telescopic end, which can extend outward relative to the swing frame under the action of the telescopic component. A number of feeding components are provided, spaced apart on the platform and located above the feeding port; The telescopic component can swing above the material feeder under the swing action of the swing frame, causing the horizontal short ribs to extend outward, and can also retract to remove the horizontal short ribs on the magnetic strip through the material feeder.

[0011] One possible implementation also includes: An inclined slide plate is located on one side of the platform and extends obliquely downward to above the feeding port, used to guide the horizontal short ribs through the feeding port; An outer baffle is provided on the storage rack and located on the other side of the feeding port, used to cooperate with the inclined slide to guide the horizontal short rib through the feeding port.

[0012] One possible implementation also includes: A buffer rod is slidably mounted on the storage rack in a direction perpendicular to the axial direction of the transverse short rib. A buffer roller is rotatably located at the outer end of the buffer rod. The buffer roller can extend into the storage space under the sliding action of the buffer rod to receive the short horizontal ribs that enter from the feeding port and fall downwards.

[0013] In one possible implementation, the storage rack includes: The flat frame body has two components, which are spaced apart and arranged parallel to each other, and the two flat frame bodies form the storage space.

[0014] In one possible implementation, the storage space is provided with a straight guide edge and an inclined guide edge; the upper and lower ends of the straight guide edge extend vertically to the feeding port and the discharge port, respectively; the upper and lower ends of the inclined guide edge extend to the feeding port and the discharge port, respectively; the straight guide edge and the inclined guide edge cooperate with each other to guide the horizontal short rib to move to the discharge port.

[0015] In one possible implementation, the inclined guide edge includes a straight section and an inclined section fixedly connected. The lower end of the straight section extends to the discharge port, and the straight section and the straight guide edge are arranged parallel to each other. The inclined section extends obliquely upward in a direction gradually away from the straight guide edge to the feeding port. The inclined section cooperates with the straight guide edge to guide the horizontal short ribs to fall, and the straight section cooperates with the straight guide edge to store the horizontal short ribs.

[0016] The significant technical effects of this invention are as follows: Compared with the prior art, the automatic feeding device for short horizontal ribs of metal mesh provided in this embodiment achieves single-rib feeding through a designed feeding unit. By gradually lowering the short horizontal ribs from top to bottom, the device ensures individual feeding of the short horizontal ribs, avoiding interference with the normal feeding of long horizontal ribs. Simultaneously, it reduces the dispersion of welding processes, enabling the welding of both long and short ribs to be completed on the same welding equipment, simplifying the welding process, improving the effective utilization of workshop space, and increasing welding efficiency. Furthermore, it avoids the punching operation in traditional welding production methods, reducing waste material generation and improving the utilization rate of raw materials.

[0017] Continuous welding with the same welding equipment reduces the need for repositioning of welding reference points. Metal mesh can be formed in one welding operation, reducing the production, transfer, and repositioning of semi-finished products. This greatly improves the space utilization and equipment utilization rate of the production workshop, while also improving the accuracy of welding the position of reinforcing bars and reducing the production of defective products to a certain extent.

[0028] Please see Figures 1-9This illustration shows an automatic feeding device for horizontal short ribs of metal mesh according to an embodiment of the present invention, used to transport horizontal short ribs to welding unit 90. The automatic feeding device includes components such as platform 10, storage rack 20, and unloading unit 30. The unloading unit 30 includes a transfer shaft 31, clamping components 32, and a horizontal guide frame 34. There are two clamping components 32. The lower end of the storage rack 20 is provided with an outer guide plate 33. Each set of clamping components 32 includes two clamping rings 321. The horizontal guide frame 34 has a guide surface 341. The storage rack 20 is placed vertically, and the storage space 204 is generally flat. Furthermore, it extends vertically; the slots 322 on the two clamping rings 321 of the same group partially overlap, and the partially overlapping through area forms a snap-fit ​​space 323. The two sides of the snap-fit ​​space 323 are respectively one side of the two slots 322; the clamping ring 321 is formed by assembling two semi-circular rings together. The two semi-circular rings are connected together by a locking member to fix the relative position between the clamping ring 321 and the transfer shaft 31; by disassembling and assembling the two semi-circular rings, the overlap of the two slots 322 can be adjusted, thereby adjusting the size of the snap-fit ​​space 323 to accommodate horizontal short ribs of different diameters.

[0029] The specific operation process is as follows: One by one, the horizontal short ribs are placed into the storage space 204 through the feeding port at the upper end of the storage rack 20. Using their own weight, the horizontal short ribs fall downwards to the discharge port. They then enter the clamping space 323 formed by the two slots 322, which supports the ribs. The overlap of the two slots 322 can be adjusted to ensure that only one horizontal short rib can be supported in the clamping space 323, achieving single-rib discharge and support. Then, an external force is applied to drive the transfer shaft 31 to rotate. The rotating transfer shaft 31 causes the clamping space 323 and the horizontal short ribs to swing downwards synchronously. Driven by the rotation of the transfer shaft 31, the clamping space 323 carries the horizontal short ribs into and through the transition space 331. With the guidance and limiting effect of the outer guide plate 33, the horizontal short ribs are successfully discharged. The single horizontal short bar is now being transported downwards. As the transport shaft 31 rotates, the horizontal short bar slides out from the transition space 331. At this time, the rotation angle of the transport shaft 31 is greater than 90 degrees and less than 180 degrees. The slid-out horizontal short bar falls downwards onto the guide surface 341, which has slid horizontally below the transport shaft 31. The guide surface 341 includes at least two downward-sloping sections. In this example, the guide surface 341 is divided into two sections. The first section is located below the transport shaft 31 and is used to receive the horizontal short bar falling from the snap-fit ​​space 323. The horizontal short bar rolls diagonally downwards onto the first section to the second section, and then rolls upwards onto the longitudinal bar on the lower welding seat 91 with the help of the guide of the second section. Then, an external force is applied to drive the upper welding seat 92 to slide downwards until the upper welding seat 92 slides down to the preset position to complete the welding of the reinforcing bars (welding of the horizontal and longitudinal bars).

[0030] Then, the transfer shaft 31 rotates in the opposite direction at a certain angle until the clamping space 323 is aligned with the discharge port again to receive the next horizontal short rib; at the same time, considering that the metal mesh is a mixture of horizontal short ribs and horizontal long ribs, after the current required horizontal short ribs are welded, the horizontal guide frame 34 slides away from the upper welding seat 92 to wait for the next horizontal short rib to be fed, and the welding unit 90 feeds and welds the horizontal long ribs (related equipment parts are not included in this solution, so they are not shown).

[0031] In the above process, the rotational driving force of the transfer shaft 31 can be provided by existing equipment that can provide rotational drive; in this example, for example... Figure 1 and Figure 5 As shown, the rotational driving force of the transfer shaft 31 comes from a drive unit 1 mounted on the storage rack 20. Drive unit 1 includes a first transmission sprocket, a second transmission sprocket, a transmission chain, and a telescopic cylinder 1. The first transmission sprocket is coaxially and linked to the transfer shaft 31 via a transmission shaft. The second transmission sprocket is rotatably connected to the storage rack 20. The transmission chain is sleeved around the outer circumference of the first and second transmission chains, achieving a transmission connection. The first telescopic cylinder is located on the side of the storage rack 20, and the outer end of the telescopic rod of the first telescopic cylinder is fixedly connected to the transmission chain. The telescopic operation of the first telescopic cylinder drives the transfer shaft 31 to rotate reciprocally. The telescopic operation is controlled by a solenoid valve, which is electrically connected to an external control console. The external control console can be any existing electrical control device that can receive, collect, store, analyze, and provide judgment results for electrical signals, as well as send execution command signals to the corresponding solenoid valves. The power to drive the upper welding seat 92 to slide downward comes from existing linear drive devices, such as hydraulic cylinders or electric cylinders, which are not shown in the figure. The horizontal sliding drive force of the horizontal guide 34 comes from existing linear drive devices, such as hydraulic cylinders or electric cylinders, which are not shown in the figure.

[0032] Furthermore, a push rod is slidably provided on one side of the horizontal guide frame 34, such as... Figure 1 and Figure 5 As shown, after the horizontal short rib rolls down from the second inclined surface onto the lower welding seat 91, an external force is applied to drive the push rod to slide towards the lower welding seat 91. The external force is selected from existing equipment that can provide linear drive, such as hydraulic cylinders, electric cylinders, etc. The horizontally sliding push rod pushes the horizontal short rib to a preset position, improving the consistency of the horizontal short rib loading position, improving welding quality, avoiding defective welds, and reducing the waste of raw materials.

[0033] Compared with existing technologies, the automatic feeding device for short horizontal ribs of metal mesh provided in this embodiment achieves single feeding of short horizontal ribs through the designed feeding unit 30. By gradually lowering the short horizontal ribs from top to bottom, the device ensures individual feeding of the short horizontal ribs, avoiding mutual interference with the normal feeding of long horizontal ribs. At the same time, it reduces the dispersion of welding processes, enabling the welding of both long and short ribs to be completed on the same welding equipment, simplifying the welding process, improving the effective utilization rate of workshop workspace, and increasing welding efficiency. It also avoids the punching operation in traditional welding production methods, reduces the generation of waste material, and improves the utilization rate of raw materials.

[0034] Continuous welding with the same welding equipment reduces the need for repositioning of welding reference points. Metal mesh can be formed in one welding operation, reducing the production, transfer, and repositioning of semi-finished products. This greatly improves the space utilization and equipment utilization rate of the production workshop, while also improving the accuracy of welding the position of reinforcing bars and reducing the production of defective products to a certain extent.

[0035] Please see Figure 1 and Figure 5 In some embodiments, the automatic feeding device is refined, with several storage racks 20 and feeding units 30. The specific number is adaptively adjusted according to the reserved openings on the metal mesh. Multiple horizontal short ribs are fed synchronously through multiple storage racks 20 and feeding units 30. In this example, there are two storage racks 20 and two feeding units 30, corresponding to a metal mesh with only one reserved opening in the axial direction of the horizontal rib.

[0036] Please see Figure 1 , Figure 5 and Figure 7 In some embodiments, the automatic feeding device is refined by adding a material detection sensor 21 to the storage rack 20. The material detection sensor 21 can be any existing sensor or detector capable of detecting and determining whether there is a workpiece at the target location, such as a photoelectric sensor or photoelectric switch. The material detection sensor 21 is used to confirm whether the material in the storage space 204 needs to be replenished. The material detection sensor 21 is electrically connected to an external control console. The external control console can be any existing electrical control device capable of receiving, collecting, storing, analyzing, providing judgment results, and providing execution command signals. Through the detection of the material detection sensor 21, it is ensured that the horizontal short ribs can be replenished in a timely manner, ensuring the timeliness of material supply and avoiding insufficient material supply to the horizontal short ribs.

[0037] Please see Figures 1-6In some embodiments, the automatic feeding device is refined by adding a material platform 11, a swing frame 12, a magnetic strip 13, a telescopic component, and a material feeding component 14 to the platform 10. In this example, a strong magnet is selected for the magnetic strip 13. During use, the material platform 11 can be adjusted to slide according to the length specifications of the transverse ribs, thereby adjusting its position to accommodate transverse ribs of different lengths. During operation, a large number of transverse ribs can be pre-stored on the uprights 111. The uprights 111 have upward-opening grooves, and there are several uprights 111. In this example, two uprights 111 are selected to support the transverse ribs. The grooves on the uprights 111 have two ends, with the end closer to the storage rack 20 being lower than the other end. The end is positioned to facilitate material retrieval by the magnetic strip 13; an external force is applied to drive the swing frame 12 from its initial position (relative to the platform 10) towards the upright frame 111 and then stop swinging at a pre-set first angle. At this point, the swing frame 12 and the magnetic strip 13 are aligned with the horizontal short rib in the groove. Then, the telescopic component is activated to drive the magnetic strip 13 from its initial position (relative to the swing frame 12) towards the direction away from the swing frame 12 and closer to the horizontal short rib until the magnetic strip 13 comes into contact with the horizontal short rib. The magnetic attraction of the magnetic strip 13 is used to pick up a horizontal short rib. Then, the telescopic component is activated to drive the magnetic strip 13 and a horizontal short rib towards the swing frame 12 until they reach a pre-set position and then stop sliding. At this point, the picking up of the horizontal short rib is completed.

[0038] Then, a force is applied to drive the swing frame 12 to swing towards the feeding port to a preset second angle and then stop swinging. The telescopic component is activated to drive the magnetic suction strip 13 to move away from the swing frame 12 and gradually move towards the feeding port a certain distance before stopping sliding. During the sliding process, the horizontal short rib passes over the material feeding component 14 and moves to above the feeding port. The distance between the swing origin of the swing frame and the horizontal short rib is defined as L1, and the distance between the swing origin of the swing frame and the farthest end of the material feeding plate is defined as L2. At this time, L1 > L2. Then, the swing frame 12 swings towards the upright frame 111 to a preset third angle and then stops swinging. At this time, the horizontal short rib is located diagonally below the material feeding component 14. Then, the telescopic component is activated to drive the magnetic suction strip 13 to slide towards the swing frame 12 with the horizontal short rib. The horizontal short rib gradually approaches the feeding component 14 and presses against the lower surface of the feeding component 14. With the help of the feeding component 14, the horizontal short rib on the magnetic suction strip 13 is unloaded. The unloaded horizontal short rib falls down into the feeding port under its own gravity, completing the feeding operation of the horizontal short rib to the storage rack 20. After the magnetic suction strip 13 separates from the horizontal short rib, the magnetic suction strip 13 continues to slide towards the swing frame until it returns to the preset initial position and stops sliding. At this time, the swing frame 12 swings towards the upright frame 111 to the initial position and stops swinging, waiting for the next feeding operation of the horizontal short rib.

[0039] After the horizontal short rib completes its suction operation, the loading operation of the horizontal short rib can also adopt a second implementation method. For example, a force is applied to drive the swing frame 12 to swing towards the feeding port to a preset fourth angle and then stop swinging. The telescopic component is activated to drive the magnetic suction strip 13 to carry the horizontal short rib away from the swing frame 12 and gradually slide a distance towards the feeding port before stopping sliding. During the sliding process, the horizontal short rib first abuts against the upper surface of the feeding plate. The abutment position is located in the middle of the feeding plate and near the outer end. The feeding plate has a certain toughness and strength; with the help of The sliding action of the magnetic strip 13 causes the horizontal short ribs to press and bend the material feeder downwards until the magnetic strip 13 stops sliding at a preset position. At this time, the horizontal short ribs are located below the material feeder. Then, the telescopic component is activated to drive the magnetic strip 13 back to the initial position. During the sliding back process, the horizontal short ribs press against the lower surface of the material feeder. With the help of the material feeder 14, the horizontal short ribs on the magnetic strip 13 are removed. The removed horizontal short ribs fall downwards into the feeding port under their own gravity, completing the feeding operation of the horizontal short ribs to the storage rack 20.

[0040] In addition, the magnetic strip 13 can also be an electromagnet. During the first feeding operation of the horizontal short rib, when the swing frame 12 swings to the preset second angle, the magnetic strip 13 slides and drives the horizontal short rib to slide above the feeding port. Then, the magnetic strip 13 is de-energized, and the horizontal short rib falls down into the feeding port under its own weight. Then, the swing frame 12 continues to operate according to the first feeding operation, and the structure of the material feeding component 14 is used for detection to prevent the magnetic strip 13 from not separating from the horizontal short rib. When the magnetic strip 13 is an electromagnet and the second feeding operation is carried out, the magnetic strip 13, along with the horizontal short rib, presses against the material feeding component 14 and bends downward until the horizontal short rib is below the material feeding component 14. Then, the magnetic strip 13 is de-energized, and the horizontal short rib falls down into the feeding port under its own weight. The structure of the material feeding component 14 is used for detection to prevent the magnetic strip 13 from not separating from the horizontal short rib.

[0041] During the horizontal short rib suction and feeding process, the swing driving force of the swing frame 12 comes from a device that can provide rotational drive in the prior art, such as a motor. In this example, for example... Figures 1-2 and Figure 5 As shown, a telescopic cylinder 2 is provided between the platform 10 and the swing frame 12. The base of the cylinder is hinged to the platform 10, and the outer end of the cylinder's telescopic rod is hinged to the swing frame 12. The telescopic operation of the telescopic cylinder 2 can drive the swing frame 12 to reciprocate, realizing the material handling and loading operations of the horizontal short ribs. The telescopic cylinder 2 uses a solenoid valve to realize the telescopic operation and control of the telescopic length. The solenoid valve is electrically connected to an external control console. The telescopic component is selected from existing technologies that can provide linear drive, such as a cylinder or an electric cylinder. In this example, for example... Figures 1-2 and Figure 5As shown, a telescopic cylinder three is selected to drive the magnetic strip 13 to perform reciprocating sliding displacement; the telescopic cylinder three uses a solenoid valve to realize telescopic operation and control of telescopic length, and the solenoid valve is electrically connected to an external control console; the external control console can be selected from existing technologies that can at least receive, collect, store, analyze, and give judgment results for electrical signals, and can send execution command signals to the corresponding solenoid valves.

[0042] Please see as follows Figures 1-2 and Figure 5 In some embodiments, the automatic feeding device is further refined by adding a sloping slide 15 between the platform 10 and one side of the feeding port, and an outer baffle 22 on the upper side of the other side of the feeding port on the storage rack 20. The outer baffle 22 and the sloping slide 15 are located on both sides of the feeding port. When the horizontal short rib separates from the magnetic strip 13, it falls downward under its own weight. It will generally fall onto the sloping slide 15 first. With the guidance of the sloping slide 15 and the limiting of the outer baffle 22, the horizontal short rib is guided to roll down to the feeding port and enter the storage space 204. The outer baffle 22 can prevent the falling horizontal short rib from crossing the feeding port and falling to the outside, ensuring the accuracy of the falling position of the horizontal short rib.

[0043] Please see as follows Figures 1-3 , Figure 5 and Figures 7-8 In some embodiments, the automatic feeding device is refined by adding buffer rods 23 and buffer rollers 24. Several buffer rods 23 and buffer rollers 24 are provided, each corresponding to the previous one. The buffer rods 23 extend horizontally and are perpendicular to the axial direction of the transverse ribs. In this example, each storage rack 20 is equipped with two buffer rods 23 and two buffer rollers 24. The storage space 204 extends vertically. When the transverse ribs are fed, an external force is applied to drive the buffer rods 23 to slide horizontally, gradually bringing them closer to the storage space 204 until the buffer rollers 24 at the outer end of the buffer rods 23 extend into the storage space 204. The transverse ribs falling into the storage space 204 first fall onto the buffer rollers 24 for cushioning. The rotating buffer rollers 24 adjust the overall state of the transverse ribs, ensuring they are in a horizontally extending state, preventing the transverse ribs from becoming uneven and stuck in the storage space 204, which could cause subsequent operations to fail. The horizontal sliding driving force of the buffer rod 23 is selected from existing devices that can provide linear drive, such as cylinders and electric cylinders.

[0044] Please see Figures 1-2 , Figure 5 and Figures 7-8In some embodiments, the automatic feeding device is further refined. The storage rack 20 includes two flat frame bodies 201, a straight guide edge 202, and an inclined guide edge 203. The inclined guide edge 203 includes a straight section 2031 and an inclined section 2032 that are fixedly connected. In use, after the magnetic strip 13 separates from the horizontal short rib, the horizontal short rib enters the storage space 204 through the feeding port. The design of the inclined section 2032 makes the length of the feeding port greater than the length of the horizontal short rib, which facilitates the entry of the horizontal short rib and avoids the horizontal short rib getting stuck at the feeding port. The horizontal short rib that enters the storage space 204 is gradually brought to its position by the inclined guide of the inclined section 2032 until the horizontal short rib moves to be laid flat between the straight section 2031 and the straight guide edge 202. At the same time, the distance between the two flat frame bodies 201 is slightly greater than the diameter of the horizontal short rib. When the diameter of the horizontal short rib changes, the straight guide edge 202 and the inclined guide edge 203 of different thicknesses are replaced to adapt to the horizontal short rib of different diameter. In addition, when the inclined section 2032 works in conjunction with the buffer roller 24, the state of the horizontal short rib can be better adjusted, so that the horizontal short rib falls downward in a basically horizontally extended state, preventing jamming. At the same time, by adjusting the spacing between the straight guide edge 202 and the inclined guide edge 203, it can be adapted to horizontal short ribs of different lengths.
