Description

Technical Field

[0001] This invention relates to the field of column cage reinforcement skeleton forming technology, specifically, to an automated production line for reinforcement cages. Background Technology

[0002] In modern building components, steel cages primarily serve as supports, providing tensile and bending / seismic resistance. They are generally composed of longitudinal bars, stirrups, and tie bars, and are mostly fabricated using on-site manual tying. To improve production efficiency and reduce labor costs, the industry increasingly pursues the use of automated equipment, developing automatic steel cage welding technology, automatic tying guns, and stirrup fixing fixtures. However, these devices cannot automatically feed longitudinal bars or automatically arrange stirrups, still requiring manual intervention and impacting work efficiency.

[0003] In existing technologies, most auxiliary tools for tying rebar cages are used, such as the patent with authorization publication number CN212397951U, which provides a positioning device for tying rebar cages. However, the transfer and tying of longitudinal bars and stirrups still require manual intervention, and the degree of automation is not high.

[0004] Patent application CN114700446A discloses a rebar cage binding and forming production line, including a frame, a longitudinal bar temporary placement frame connected to the frame, a longitudinal bar conveying unit, a rebar cage binding unit, a rebar cage bending unit, a rebar cage unloading unit, a stirrup production unit, a stirrup conveying unit, and a stirrup assembly loading unit for conveying stirrup assemblies to the longitudinal bar conveying unit. The longitudinal bar temporary placement frame, longitudinal bar conveying unit, rebar cage binding unit, rebar cage bending unit, and rebar cage unloading unit are sequentially connected along the longitudinal bar conveying direction. The above-mentioned rebar cage binding and forming production line basically achieves fully automated production. However, in this scheme, the binding position is fixed, and the longitudinal bars are positioned and clamped by the first and last fixing devices, which drive the rebar cage as a whole to move forward, and place and bind the stirrups in sequence. The shape of the rebar cage that can be bound by this scheme is limited by the first and last fixing devices, resulting in poor versatility; in addition, only one set of robotic arms can be used for binding, and the stirrups can only be placed in one position, which limits the efficiency of automatic binding.

Detailed Implementation

[0064] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0065] This invention provides an automated production line for rebar cages, including a longitudinal bar feeding station 1, a stirrup processing station 2, a rebar cage binding station 3, and a discharge station 4. The longitudinal bar feeding station 1 automatically feeds longitudinal bars to the rebar cage binding station 3; the stirrup processing station 2 processes individual stirrups into combined stirrups and places and fixes the stirrups, which include individual stirrups and combined stirrups; the rebar cage binding station 3 automatically binds the intersections of the stirrups and longitudinal bars to form the rebar cage; the discharge station 4 discharges the formed rebar cage; the longitudinal bar feeding station 1, the rebar cage binding station 3, and the discharge station 4 are arranged in a straight line along the longitudinal direction of the rebar cage; the stirrup processing station 2 is connected in series in the production line or arranged offline.

[0066] In some embodiments, the longitudinal rib feeding station 1 includes a raw material bin 111, a longitudinal rib buffer mechanism 11, and a longitudinal rib feeding mechanism 12. The raw material bin 111 is used to store longitudinal ribs. The longitudinal rib buffer mechanism 11 includes a horizontal buffer mechanism 112 and a vertical buffer mechanism 113. The raw material bin 111 is located on one side of the horizontal buffer mechanism 112, and the longitudinal ribs are arranged horizontally in the horizontal buffer mechanism 112. The vertical buffer mechanism 113 is located on the other side of the horizontal buffer mechanism 112, and the longitudinal ribs are arranged vertically in the vertical buffer mechanism 113, that is, multiple longitudinal ribs are arranged alternately from bottom to top. The longitudinal rib feeding mechanism 12 and the horizontal buffer mechanism 112 are respectively located on both sides of the vertical buffer mechanism 113. The longitudinal ribs on the horizontal buffer mechanism 112 and the vertical buffer mechanism 113 are all conveyed by chains. When the longitudinal ribs on the horizontal buffer mechanism 112 are transmitted to the intersection of the horizontal buffer mechanism 112 and the vertical buffer mechanism 113, they are lifted by the vertical buffer mechanism 113 and move upward with the vertical buffer mechanism 113. The top of the vertical buffer mechanism 113 is provided with a guide brace 123. The guide brace 123 has an inclined surface that is inclined towards the longitudinal reinforcement feeding mechanism 12. The longitudinal reinforcement is conveyed to the longitudinal reinforcement feeding mechanism 12 through the inclined surface of the guide brace 123. The longitudinal reinforcement feeding mechanism 12 then feeds the longitudinal reinforcement conveyed by the longitudinal reinforcement buffer mechanism 11 to the steel cage binding station 3.

[0067] In this embodiment of the invention, the horizontal buffer mechanism 112 and the vertical buffer mechanism 113 are arranged with grooves at intervals to hold the reinforcing bars and are driven by a chain. In other embodiments, the horizontal buffer mechanism 112 and the vertical buffer mechanism 113 may also use a belt conveyor to transport the longitudinal reinforcing bars.

[0068] In some embodiments, the longitudinal rib feeding mechanism 12 includes a feeding support frame 124 and a feeding frame 121. The feeding support frame 124 provides support for the longitudinal rib feeding mechanism 12. The feeding frame 121 is above the feeding support frame 124 and can move laterally so that the longitudinal ribs are fed at different positions. Rollers 122 driven by a motor are arranged at intervals below the feeding frame 121. The rotation of the rollers 122 realizes their lateral movement above the support frame, driving the longitudinal ribs to move along the longitudinal rib length direction, thereby driving the longitudinal ribs forward.

[0069] Preferably, the longitudinal rib feeding mechanism 12 is provided with two sets of feeding racks 121, and the two sets of feeding racks 121 operate simultaneously, which can significantly improve work efficiency. In some other embodiments, more feeding racks 121 can be provided, provided that the space arrangement requirements are met.

[0070] In some embodiments, the stirrup processing station 2 includes an electric welding assembly 21, a stirrup hopper 23, and a transfer robot 22. The electric welding assembly 21 welds individual stirrups together to fix the shape of the stirrups and form a combined stirrup. The electric welding assembly 21 can be an electric welding platform or a welding robot. The stirrup hopper 23 is used to store stirrups (including individual stirrups and combined stirrups). The transfer robot 22 is arranged between the electric welding assembly 21 and the stirrup hopper 23. The transfer robot 22 puts the welded combined stirrups into the stirrup hopper 23.

[0071] The rebar tying station 3 is located after the longitudinal bar feeding mechanism 12. In some embodiments, the rebar tying station 3 includes a tying support frame 35, a longitudinal bar threading mechanism 31, a fixing groove 33, a stirrup feeding mechanism 32, and an automatic tying mechanism 34. The tying support frame 35 provides support and a foundation for the rebar tying station 3. The longitudinal bar threading mechanism 31 is connected to the top crossbeam of the tying support frame 35, thereby fixing it above the tying support frame 35. The longitudinal bar threading mechanism 31 is symmetrically arranged on both sides of the rebar tying station 3, so that the longitudinal bars remain in the rebar cage. Binding position; the fixing groove 33 is located at the bottom of the binding support frame 35. The fixing groove 33 is used to fix the steel cage so that the entire steel cage remains stable during the manufacturing process; the stirrup feeding mechanism 32 is located on one side of the binding support frame 35. The stirrup feeding mechanism 32 places the stirrups vertically in the fixing groove 33 as required; the automatic binding mechanism 34 is symmetrically arranged on both sides of the steel cage binding station 3. The automatic binding mechanism 34 is connected to the two vertical columns of the binding support frame 35. The automatic binding mechanism 34 binds and fixes the intersection of the stirrups and longitudinal bars so that the steel cage is formed.

[0072] To fix the position of the stirrups and ensure the stability of the entire rebar cage during fabrication, thus achieving a fixed rebar cage structure, in some embodiments, the fixing groove 33 includes a bottom fixing groove 332. The bottom fixing groove 332 is fixed to sliding mechanisms 333 at both ends. The sliding mechanisms 333 are arranged at the two longitudinal end faces of the binding support frame 35 and are connected to the columns of the binding support frame 35 via slide rails. The bottom fixing groove 332 can move up and down as a whole, following the sliding mechanisms 333. Since the rebar cage binding station 3 is equipped with the fixing groove 33, the stirrups are placed first, then the longitudinal bars are placed, and then binding is performed. During the binding process, the position of the rebar cage remains unchanged, while the automatic binding mechanism 34 moves and feeds, achieving fully automatic binding without manual operation.

[0073] In some embodiments, the stirrup feeding mechanism 32 includes a stirrup feeding slide rail 321, a stirrup box 323, and a stirrup feeding robot 322. The stirrup feeding slide rail 321 is fixed to the ground and arranged on the side of the rebar cage binding station 3. The stirrup box 323 is used to place the stirrups. The stirrup feeding robot 322 is fixed to the stirrup box 323, and the stirrup box 323 and the stirrup feeding robot 322 slide together along the stirrup feeding slide rail 321. When placing the stirrups, the stirrup feeding robot 322 picks up the stirrups in the stirrup box 323 and moves them to the placement position. The stirrups are placed vertically in the fixed groove 33 as required. After the stirrups are placed, the stirrup feeding robot 322 and the stirrup box 323 return to the starting point to pick up the stirrups and wait for the next action. The starting point is a defined point that can be any point within the sliding stroke range of the stirrup feeding slide rail 321. In this embodiment, the starting point is located on the side closer to the stirrup processing station 2.

[0074] In the above embodiment, the stirrup processing station 2 can be connected in series with the rebar cage production line. The transfer robot 22 directly puts the stirrups into the stirrup box 323 of the rebar cage binding station 3. The stirrup hopper 23 is the stirrup box 323. During automatic stirrup feeding, the stirrup box 323 and the stirrup feeding robot 322 move on the side of the binding station, allowing the stirrup processing station 2 to work offline. After the stirrups are centrally processed, they are transferred to the stirrup box 323 of the binding station for a second time.

[0075] In some embodiments, the longitudinal reinforcement threading mechanism 31 includes a sliding mechanism, a longitudinal reinforcement threading bracket 312, and guide rollers 311. The sliding mechanism is fixed to the top longitudinal beam of the binding support frame 35; the longitudinal reinforcement threading bracket 312 moves left and right along the sliding mechanism; the guide rollers 311 are fixed to the end of the longitudinal reinforcement threading bracket 312 and are arranged at intervals along the longitudinal direction; the guide rollers 311 are at the same height as the rollers 122 of the longitudinal reinforcement feeding mechanism 12, and the guide rollers 311 receive the longitudinal reinforcement conveyed by the feeding frame 121, and are provided with end stops 313 at their ends to keep the longitudinal reinforcement at the binding position of the reinforcing cage. Preferably, the longitudinal reinforcement threading mechanism 31 is provided with multiple motive force guide rollers 311, which can extend and retract to position and convey the longitudinal reinforcement.

[0076] Automatic binding mechanisms 34 are symmetrically arranged on both sides of the binding station to bind and fix the intersection of stirrups and longitudinal bars, thus forming the rebar cage. In some embodiments, the automatic binding mechanism 34 includes a binding gun support 344, a lateral fixing groove 343, a binding robot 341, and an automatic binding gun 342. The binding gun support 344 is connected to the binding support frame 35 via a slide rail and can move up and down along the binding support frame 35. The fixing groove 33 is a split structure, including a bottom fixing groove 332 and a lateral fixing groove 343. The lateral fixing groove 343 is located on the binding gun support 344, close to the inner side of the rebar cage binding station 3, and is used to stabilize the rebar cage. Specifically, the binding support frame 35 is provided with a guide mechanism 334, and the lateral fixing groove 343 is fixed... The lateral fixing groove 343 is fixed on the guide mechanism 334 and moves up and down and left and right along the guide mechanism 334; the binding robot 341 is connected to the binding gun bracket 344 through the slide rail mechanism, and at least two binding robots 341 are arranged along the longitudinal direction of the slide rail mechanism; the binding robot 341 can feed along the longitudinal direction of the slide rail mechanism, and can extend laterally and move vertically to adjust its position; the automatic binding gun 342 is fixed to the end of the binding robot 341, and the automatic binding gun 342 can rotate. Preferably, the automatic binding gun 342 has 6 degrees of freedom of translation and rotation, which can cover all binding points of the rebar cage. The automatic binding gun 342 performs binding operations at the binding points.

[0077] In this embodiment of the invention, the height of the longitudinal reinforcement threading mechanism 31 is kept fixed, and the steel cage of the steel cage binding station 3 can be raised and lowered with the fixed groove 33 to raise the steel cage to the height to be threaded with longitudinal reinforcement, so that the longitudinal reinforcement can be sent to different height positions of the steel cage. At the same time, after the longitudinal reinforcement is in place, the longitudinal reinforcement threading mechanism 31 completes the feeding and waits for binding, thereby improving the efficiency of threading longitudinal reinforcement.

[0078] The unloading station 4 is arranged after the binding station. In some embodiments, the unloading station 4 includes a ground rail 42 and an unloading trolley 41. The ground rail 42 is arranged longitudinally along the production line at the center of the rebar cage binding station 3. The unloading trolley 41 moves along the ground rail 42 to the bottom of the formed rebar cage in the rebar cage binding station 3, and drives the formed rebar cage to move along the ground rail 42 to the designated position.

[0079] To further improve the quality of rebar cage binding, after the rebar cage binding station 3 is completed, the unloading trolley 41 enters under the rebar cage at the rebar cage binding station 3, and the fixing groove 33 loosens the rebar cage, allowing the bound rebar cage to fall onto the unloading trolley 41; the unloading trolley 41 carries the rebar cage into the unloading station 4, where a lifting device 43 is installed at the top. The lifting device 43 can be, for example, an electric hoist. The electric hoist at the unloading station 4 lifts the rebar cage, and manual re-binding is performed on any missing binding positions. Finally, the gantry crane takes it away and transports it to the finished product storage yard.

[0080] In some other embodiments, the discharge mechanism may also be a mobile gantry crane, which carries the steel cage into the discharge station 4 and moves it to the designated position.

[0081] The automated production line for rebar cages in the above embodiments of the present invention mainly includes the following processing routes: stirrup assembly and welding, automatic placement and fixing of stirrups according to their positions, automatic feeding of longitudinal bars to the rebar cage processing position, automatic binding by a robotic arm, and automatic receiving of rebar cages by a finished product receiving cart. All bars are placed on the fixed frame, and then the longitudinal bars are threaded into the cage. One longitudinal bar is threaded in and bound, and then other longitudinal bars are threaded in until completion. The position of the rebar cage remains unchanged throughout the entire process. This processing route is applicable to most shapes of rebar cages, such as straight, L-shaped, and T-shaped, and has strong versatility.

[0082] This invention achieves fully automated production of steel cages by automatically releasing stirrups, threading longitudinal bars, tying, and discharging materials, eliminating the need for manual intervention in the entire steel cage production process.

[0083] The automated production line for rebar cages provided by this invention adopts a fully automated method to produce rebar cages. Based on this process route, multiple binding robots can be arranged to further improve the production efficiency of rebar cage forming and realize the factory production of rebar cages.
