[0068] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0069] To address the problems in existing rebar cage production technology, this application provides an automated processing line, particularly suitable for the fabrication of rectangular rebar cages, such as... Figures 1-16As shown, the processing production line provided in this application specifically includes a stirrup placement device 1, a single longitudinal bar conveying device 2, a synchronous conveying device 3, and an assembly and welding device 5. The stirrup placement device 1 is used to place the stirrups, fixing the preset spacing and quantity of the stirrups. Then, using an AGV trolley and a stirrup lateral movement mechanism 8, the stirrups and the clamping system are transferred together to the assembly and welding device 5. Lower supports are provided at the stirrup placement device 1 and the assembly and welding device 5 for temporarily placing the clamping system. The single longitudinal bar conveying device 2... Multiple longitudinal reinforcing bars 9 are fed into a synchronous conveying device 3. The synchronous conveying device 3 has positioning rollers 310 corresponding to the reinforcing cage. The synchronous conveying device 3 is directly opposite the assembly and welding device 5, so that multiple longitudinal reinforcing bars 9 can be synchronously conveyed to the assembly and welding device 5 to be assembled with stirrups into a reinforcing cage. The stirrup clamping system and longitudinal reinforcing bars 9 are synchronously driven by external force to pass through the welding robot 6. The welding robot 6 is used for welding to form a finished reinforcing cage. In this application, the stirrup clamping system can be moved by an AGV trolley, and the longitudinal reinforcing bars 9 can be lifted by a gantry crane.

[0070] In the processing production line provided in this application, the single longitudinal rib conveying device 2, the synchronous conveying device 3, and the assembly and welding device 5 are linearly distributed. The single longitudinal rib conveying device 2 is directly opposite the synchronous conveying device 3. The synchronous conveying device 3 and the assembly and welding device 5 are slidably assembled on the same ground rail 7, so that the synchronous conveying device 3 can push the longitudinal rib 9 to the assembly and welding device 5.

[0071] The stirrup placement device 1 includes a clamping system and a transverse centering fixture. The lower part of the clamping system is a square truss, the shape of which is adapted to the steel cage. Multiple stirrup clamping mechanisms 311 are provided on both sides of the clamping system at intervals. The spacing between the stirrup clamping mechanisms 311 in the same row is adapted to the design spacing of the stirrups. The stirrup clamping mechanisms 311 on both sides correspond one-to-one, and the number is adapted to the number of stirrups corresponding to the steel cage. Thus, the stirrups are clamped and positioned by the stirrup clamping mechanisms 311. The transverse centering fixture includes two centering plates 107 distributed on both sides of the clamping system. The length of the centering plate 107 is adapted to the steel cage. The centering plate 107 is located in the middle of the stirrups and is fixed on the drive frame 102. It is driven by the drive frame 102 to move laterally along the steel cage. As the two centering plates 107 are squeezed from both sides of the steel cage, multiple stirrups are aligned with each other. The limit of the squeezing plate makes the stirrups center relative to the clamping system, thereby ensuring the positioning accuracy of the stirrups.

[0072] The single longitudinal reinforcement conveying device 2 includes a wire threading frame 201, a conveying rail 202, and conveying wheels 205. Two wire threading frames 201 are distributed opposite each other, and the height of the wire threading frames 201 is adapted to the height of the synchronous conveying device 3. The two wire threading frames 201 can be slidably assembled along the transverse direction of the reinforcing cage, thereby allowing the position of the wire threading frames 201 to be adjusted and to convey longitudinal reinforcement 9 at different transverse positions. In order to convey longitudinal reinforcement 9 in the longitudinal direction, the conveying rail 202 points towards the synchronous conveying device 3 and is slidably assembled along the longitudinal direction on the inner side of the wire threading frame 201, thereby allowing for transverse and longitudinal position adjustments. Furthermore, the conveying wheels 205 are spaced apart within the conveying rail 202. The conveying rail 202 can be a V-shaped groove, and the conveying wheels 205 are provided at least at the end of the conveying rail 202 away from the synchronous conveying device 3, thereby driving the longitudinal reinforcement 9 to be conveyed to the synchronous conveying device 3. There can be multiple conveying wheels 205, which are evenly distributed within the conveying rail 202.

[0073] The synchronous conveying device 3 includes a pusher car and a longitudinal reinforcement spacing adjustment mechanism. The pusher car is a square truss welded from square steel and has an internal space adapted to the shape of the reinforcing cage. Multiple pusher cars are slidably mounted on a ground rail 7. Specifically, the pusher cars have traveling wheels at their bottom, each connected to a drive motor. This allows for spacing or positional movement according to actual needs, driving multiple longitudinal reinforcements 9 to be synchronously conveyed to the assembly and welding device 5. In this embodiment, the drive motor can be directly connected to the traveling wheels, or a rack can be installed on the ground rail 7, with the drive motor located at the bottom of the pusher car, and the pusher car is driven by gear meshing with the rack.

[0074] Four longitudinal reinforcement spacing adjustment mechanisms are provided around the pusher vehicle. The four longitudinal reinforcement spacing adjustment mechanisms correspond to the four sides of the steel cage, thereby supporting the longitudinal reinforcement 9 on each side of the steel cage. Multiple positioning rollers 310 are slidably mounted on the rail plate 302 of the longitudinal reinforcement spacing adjustment mechanism. The positioning rollers 310 are used to support the longitudinal reinforcement 9. The positioning rollers 310 can adjust the spacing of the longitudinal reinforcement 9 of the steel cage according to actual needs by sliding, thus making it suitable for different models of steel cages.

[0075] In an optional embodiment, the pusher includes a bottom frame 305, an upper frame 303, a left frame 304, and a right frame 301, for mounting four longitudinal rib spacing adjustment mechanisms respectively. The bottom frame 305 and the upper frame 303 are provided with adjustment rails 306 corresponding to the left frame 304 and the right frame 301, so that the spacing between the left frame 304 and the right frame 301 can be adjusted between the bottom frame 305 and the upper frame 303. Specifically, the left frame 304 and the right frame 301 are adjusted independently by a seventh driver, which can be any one of a stepper motor, an electric lead screw, or a cylinder.

[0076] Furthermore, an adjustment plate 307 is provided on the upper frame 303. The adjustment plate 307 is slidably mounted on the upper frame 303 along the longitudinal direction. Its lower end is connected to the corresponding longitudinal reinforcement spacing adjustment mechanism. The edge of the adjustment plate 307 is provided with a rack. The adjustment plate 307 is driven by the stepper motor and gears set on the upper frame 303 to adjust the longitudinal reinforcement spacing mechanism, thereby making it suitable for different types of steel cages.

[0077] In this embodiment, the number of pushers in the synchronous conveying device 3 is 4, and the number of pushers in the assembly and welding device 5 is 4 or 5, wherein one pusher away from the synchronous conveying device 3 is used to pull the steel cage.

[0078] The assembly and welding device 5 includes a pusher cart, a bracket 501, a stirrup straightening mechanism, and a welding robot 6. The pusher cart in the assembly and welding device 5 has the same structure as the pusher cart in the synchronous conveying device 3, and both are equipped with a longitudinal rib spacing adjustment mechanism.

[0079] Similarly, multiple push carts are spaced apart on the ground rail 7, which is a straight rail. The longitudinal rib spacing adjustment mechanism on the push cart of the assembly and welding device 5 is the same as the longitudinal rib 9 spacing of the synchronous conveying device 3, so that the longitudinal rib 9 conveyed by the synchronous conveying device 3 can be received smoothly. Multiple brackets 501 are evenly distributed on the ground rail 7 corresponding to the position of the assembly and welding device 5. The multiple brackets 501 are evenly distributed along the length of the ground rail 7. A lifting mechanism is provided below the bracket 501. The lifting mechanism can be an eighth drive 509, specifically a cylinder or a hydraulic cylinder, to lift the clamping system and position the stirrups. Two corresponding rollers 508 are provided on the bracket 501. Specifically, during the process of placing the clamping system, the push cart moves aside to make room. After the clamping system is laterally moved, the push carts are reset in sequence. During the reset process, when the push cart passes the bracket 501, the bracket 501 retracts. The clamping system continues to remain stable under the support of other brackets 501. In order to perform positioning, a position sensor corresponding to the push cart is provided on the ground rail 7 to automatically control the lifting of the bracket 501.

[0080] Then, the longitudinal reinforcement 9 is pushed into place by the pusher. During the pushing process, the pusher close to the assembly and welding device 5 moves back and forth until the longitudinal reinforcement 9 is pushed. At this time, under the support of the positioning roller 310, the longitudinal reinforcement 9 and the stirrups form a steel cage for subsequent welding. A welding robot 6 is provided on one side of the ground rail 7. First, the steel cage between the first and second pushers away from the synchronous conveying device 3 is welded. Then, the pusher away from the synchronous conveying device 3 pulls the steel cage through the welding robot 6 for welding.

[0081] In this embodiment, a clamping mechanism 311 corresponding to the longitudinal rib 9 is provided on the positioning roller 310, so as to meet the needs of pushing or pulling. During the pulling process, the clamping system moves synchronously to ensure the relative position of the longitudinal rib 9 and the stirrup.

[0082] In an optional embodiment, during the pushing process of the longitudinal reinforcement 9, in order to maintain the stability of the stirrups, a stirrup straightening mechanism is provided on the pushing vehicle. The stirrup straightening mechanism is located above the steel cage and is equipped with multiple clamps for clamping and straightening the stirrups to ensure the stability of the stirrups. A lifting mechanism corresponding to the support beam 502 is provided on the pushing vehicle. The lifting mechanism can be a pneumatic cylinder or a hydraulic cylinder. A fourth slide rail corresponding to the support beam 502 and extending longitudinally is provided on the pushing vehicle. After the longitudinal reinforcement 9 is pushed, the stirrups are released to facilitate traction.

[0083] In an optional embodiment, the longitudinal reinforcement spacing adjustment mechanism includes a rail plate 302, adjusting members 312, a scissor adjuster, and a first driver 309. The rail plate 302 is a rectangular plate and is fixed on the pusher vehicle. The rail plates 302 at the bottom can be horizontally distributed to minimize the bottom gap and improve the stability of the pusher vehicle. Multiple adjusting members 312 are slidably assembled on the rail plate 302. The adjusting members 312 are strip plates, and the rail plate 302 has a track corresponding to the adjusting members 312. The length of the adjusting members 312 is adapted to the width of the rail plate 302. A positioning roller 310 is connected to one side of the rail plate 302 corresponding to the steel cage to support the longitudinal reinforcement 9 of the steel cage. The longitudinal reinforcement spacing adjustment mechanism located on the bottom frame 305 can be connected to the adjusting members 312 and the positioning roller 310 through a support plate. A V-shaped clamping member is provided on the miniature push rod located on the bottom frame 305, and the V-shaped clamping member extends above the corresponding positioning roller 310.

[0084] Two scissor adjusters are distributed parallel to each other along the length of the track plate 302. Each scissor adjuster includes multiple scissor adjustment units 308 that are hinged to each other. Each scissor adjustment unit 308 includes two scissor plates that cross each other in a scissor pattern. The scissor adjustment units 308 of the two scissor adjusters are connected at intervals to divide the multiple adjustment elements 312 into single-array and double-array groups. Specifically, the adjustment elements 312 in the single-array group are connected to a scissor adjustment unit 308 at a relative position of one scissor adjuster, and the adjustment elements 312 in the double-array group are connected to a scissor adjustment unit 308 at a relative position of another scissor adjuster. One of the hinge axes of the scissor adjustment unit 308 is connected to the adjustment element 312. This makes full use of space and reduces the length of the hinge rod of the scissor adjustment unit 308.

[0085] The two first drivers 309 can be stepper motors. The scissor adjustment unit 308 at one end of the scissor adjuster is hinged to the rail plate 302. A rack is connected to one of the hinge axes of any two adjacent scissor adjustment units 308. The first drivers 309 are mounted on the rail plate 302 and are driven by the gear meshing with the rack. The two first drivers 309 drive the two scissor adjusters respectively to adjust the position of the adjustment pieces 312 in the single array and double array respectively. The spacing is adjusted by using the scissor adjusters to adapt to the distribution of longitudinal ribs 9 with different spacing.

[0086] In an optional embodiment, for pushing the longitudinal reinforcement 9, a clamping mechanism 311 corresponding to the longitudinal reinforcement 9 is provided on the longitudinal reinforcement spacing adjustment mechanism. The clamping mechanism 311 can be a miniature push rod provided on the adjusting member 312. The miniature push rod can be any one of an electromagnetic push rod, a pneumatic rod, or a hydraulic cylinder. The driving end of the miniature push rod points to the positioning roller 310, so that it can clamp the longitudinal reinforcement 9 of the steel cage together with the positioning roller 310. During the pushing process of the synchronous conveying device 3, the four pushing cars first move as a whole towards the assembly and welding device 5 until they are in front of the assembly and welding device 5. The longitudinal reinforcement 9 is stacked, and then the pusher of the assembly welding device 5 clamps the longitudinal reinforcement 9. The synchronous conveying device 3 retracts and continuously pushes the longitudinal reinforcement 9 by reciprocating the pusher close to the assembly welding device 5. During the clamping and pushing process of the synchronous conveying device 3, the assembly welding device 5 cancels the clamping of the longitudinal reinforcement 9. During the retraction process of the pusher of the synchronous conveying device 3 releasing the longitudinal reinforcement 9, the assembly welding device 5 clamps the longitudinal reinforcement 9 until the longitudinal reinforcement 9 is completely pushed and the synchronous conveying device 3 resets. At this time, the assembly welding device 5 clamps the longitudinal reinforcement 9 for welding and pulls the steel cage forward as a whole under the clamping of the pusher.

[0087] Alternatively, the synchronous conveying device 3 moves back and forth near the pusher of the assembly and welding device 5 to synchronously push the longitudinal rib 9 to the assembly and welding device 5. During the forward pushing of the longitudinal rib 9, the pusher of the synchronous conveying device 3 clamps the longitudinal rib 9, and the pusher of the assembly and welding device 5 releases the longitudinal rib 9. During the retraction of the pusher of the synchronous conveying device 3 near the assembly and welding device 5, the pusher of the synchronous conveying device 3 releases the longitudinal rib 9, and the pusher of the assembly and welding device 5 clamps the longitudinal rib 9. This reciprocating motion continues until the longitudinal rib 9 is pushed out.

[0088] In one optional embodiment, the cable threader 201 is a vertical frame with a base frame 204 at its bottom. The base frame 204 is welded from square steel, and multiple first slide rails 206 distributed laterally are provided on the base frame 204. Two cable threaders 201 are slidably assembled at both ends of the first slide rails 206, thereby allowing lateral displacement on the base 101. A second driver corresponding to the cable threader 201 is provided on the base frame 204. The second driver can be a stepper motor, a cylinder, or a hydraulic cylinder, without further limitation. Multiple second slide rails 203 are evenly distributed on the threading frame 201 to ensure the smooth movement of the threading frame 201. The conveying rail 202 is slidably mounted on the second slide rails 203. The threading frame 201 is provided with a third driver corresponding to the conveying rail 202. The conveying wheel 205 is set at the bottom of the conveying rail 202. The conveying rail 202 is a V-shaped groove and is driven by a fourth driver. Preferably, there is a conveying wheel 205 at both ends of the conveying rail 202. The fourth driver is preferably a stepper motor. The second driver and the third driver can be stepper motors, cylinders or hydraulic cylinders. No further restrictions are imposed here. The specific installation structure is selected according to the actual structure.

[0089] In an optional embodiment, the stirrup clamping mechanism 311 includes a fixing plate 108 and a clamping plate 109. The fixing plate 108 is a strip plate fixed longitudinally on the clamping system. The two fixing plates 108 are distributed in parallel. A strip-shaped notch corresponding to the stirrup is provided in the middle of the fixing plate 108. The length of the strip-shaped notch is adapted to the length of the fixing plate 108, and the width is slightly larger than the diameter of the stirrup.

[0090] Two clamping plates 109 are provided in the same stirrup clamping mechanism 311. The two clamping plates 109 are hinged between two fixed plates 108. The two fixed plates 108 are located on both sides of the strip-shaped notch and are symmetrically distributed about the strip-shaped notch. On both sides of the clamping plates 109 of the fixed plates 108, there are elastic elements 103 corresponding to the clamping plates 109. The elastic elements 103 can be springs. Under the drive of the springs, the lower ends of the clamping plates 109 have a tendency to clamp each other. Thus, after the stirrup is inserted, the deformation compresses both sides of the stirrup, thereby maintaining the stability of the stirrup.

[0091] In this embodiment, the length of the clamping plate 109 is adapted to the length of the fixing plate 108. The upper end of the clamping plate 109 extends upward beyond the fixing plate 108, and the inner side of the portion of the upper end of the clamping plate 109 extending beyond the fixing plate 108 is provided with an inclined surface to form a V-shaped inlet for the corresponding stirrup, which facilitates the insertion of the stirrup. The spacing between the two clamping plates 109 in the parallel state is adapted to the thickness of the stirrup. In response to the insertion of the stirrup into the strip notch, the two clamping plates 109 are driven to be in a parallel state and clamp the stirrup. In order to reduce the volume of the stirrup clamping mechanism 311, the adjacent sides of the lower half of the two clamping plates 109 are provided with a stepped platform with reduced thickness, so that after the stirrup is removed, the two clamping plates 109 cross in a scissor-like manner through the stepped platform, thereby fully maintaining the angle of the upper V-shaped inlet and ensuring smooth insertion of the stirrup. Preferably, the fixing plate 108 can support more than 3 limbs of the stirrup.

[0092] In an optional embodiment, the clamping system includes a main beam 105 and a crossbeam 104. The main beam 105 is made of square steel, and the two main beams 105 are distributed in parallel for the installation of the stirrup clamping mechanism 311. Multiple crossbeams 104 are evenly distributed between the two main beams 105, thus forming a square planar truss. The crossbeam 104 includes two sleeves that are nested together. Locking bolts are provided on the outer sleeves, so that the width of the clamping system can be adjusted according to actual needs, making it suitable for different types of square steel cages.

[0093] In an optional embodiment, the clamping system is provided with bases 101 on both sides. The bases 101 are trusses welded from square steel. The bases 101 are provided with a plurality of evenly distributed third slide rails 106 pointing towards the clamping system. The drive frame 102 is slidably mounted on the third slide rails 106 and driven by a fifth driver. The fifth driver can be an electromagnetic push rod, a pneumatic cylinder, or a hydraulic cylinder, whichever is selected according to the actual situation. The side of the base 101 closest to the clamping system is provided with guide rollers. The guide rollers support the stirrups to prevent the stirrups from becoming unstable during the centering process. The centering plate 107 is provided with longitudinally extending limiting grooves corresponding to the stirrups. There can be two centering plates 107 on the same side.

[0094] In an optional embodiment, the stirrup straightening mechanism is disposed between two adjacent push carts of the assembly and welding device 5, and includes a support beam 502 and grippers 504. One end of the support beam 502 is connected to the top of one of the push carts and extends along the centerline of the push cart. Two sets of grippers 504 are slidably mounted on the assembly plate 503 via a main shaft 505. The assembly plate 503 is mounted below the support beam 502 via a lifting mechanism. The lifting mechanism includes at least two sixth actuators 507, which can be electromagnetic push rods or cylinders, and can be selected according to actual needs, so as to realize the longitudinal adjustment of the stirrup straightening mechanism. After the longitudinal rib 9 is pushed, the stirrup straightening mechanism releases the stirrup. The number and spacing of the grippers 504 are adapted to the stirrups at the corresponding positions. The grippers 504 on the two main shafts 505 are staggered. The two main shafts 505 are driven by two pull rods 506 to clamp the stirrups. The pull rods 506 can be cylinders or electromagnetic push rods. The mounting plate 503 is provided with mounting plates corresponding to the two main shafts 505 respectively. The main shafts 505 are slidably mounted on the mounting plates.

[0095] Furthermore, the two sets of grippers 504 are linearly distributed, and the first and second main shafts are parallel to each other. The odd-numbered grippers 504 are slidably assembled on the first main shaft and are connected and driven by the first main shaft. The even-numbered grippers 504 are slidably assembled on the second main shaft and are connected and driven by the second main shaft. This allows the odd-numbered grippers 504 and the even-numbered grippers 504 to be driven independently by the two main shafts 505, and their relative movement clamps the stirrups.

[0096] In an optional embodiment, a transverse movement mechanism 8 corresponding to the clamping system is provided on the outer side of the ground rail 7. The transverse movement mechanism 8 has multiple transverse movement rails 801 at different positions corresponding to the assembly and welding device 5. The transverse movement mechanism 8 has a telescopic transverse movement rail 801, which is driven by a stepper motor or a cylinder. The transverse movement rail 801 slides with the transverse movement mechanism 8 through a dovetail groove below, thereby ensuring the support capacity after extension. The transverse movement rail 801 extends or retracts above the ground rail 7 to perform transverse movement of the stirrup clamping system.

[0097] Furthermore, after welding is completed, the pusher pulls the clamping system along the ground rail 7 to the finished steel cage hoisting position. At this time, after the steel cage is hoisted out, the lateral movement mechanism 8 takes out the clamping system and moves it to the stirrup placement device 1 via the AGV trolley. There is a gap between the two bases 101 of the stirrup placement device 1 corresponding to the AGV trolley. The AGV trolley is equipped with a top rod corresponding to the clamping system, so as to place the clamping system in the designated position by lifting or lowering it. There are multiple stirrup buffer area brackets 4 between the stirrup placement device 1 and the ground rail 7 to buffer the clamping system after the stirrups are installed.

[0098] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention shall be within the scope of protection of the pending claims of the present invention.
