[0002] On steel bar production lines, straight steel bars are generally used as raw materials to produce steel bar products of various shapes. Because straight steel bars are much longer than their diameter, bundled steel bars often cross each other, affecting feeding efficiency. Furthermore, the steel bars are quite heavy, leading to bending and deformation during the feeding process. Connecting conveyor mechanisms of different heights is difficult, resulting in high equipment costs. The process of grabbing and handling steel bars from the storage rack to the loading rack poses significant safety hazards, resulting in high labor intensity and low work efficiency for workers. Therefore, there is an urgent need for automated equipment for steel bar feeding to improve production efficiency and reduce worker labor intensity. Utility Model Content

[0076] This utility model provides a rebar sorting and feeding device, such as... Figures 1-3 As shown, it includes a leveling device 1, a material taking device 2, a combing device 3, and a material blocking device 4 arranged sequentially along the first direction (X direction), wherein,

[0077] The leveling device 1 includes a first set of chain platforms 11 and a second set of chain platforms 12 arranged sequentially along a first direction. The first set of chain platforms 11 and the second set of chain platforms 12 have an intersecting area along the first direction. The long axis of the reinforcing bar 100 is along a second direction (Y direction), which is perpendicular to the first direction. The reinforcing bar 100 is supported on the first set of chain platforms 11, and the reinforcing bar 100 completes the leveling action during the process of being transported from the first set of chain platforms 11 to the second set of chain platforms 12.

[0078] The material handling device 2 can move along the first direction and the third direction (Z direction). The third direction (Z direction), the second direction (Y direction), and the first direction (X direction) are perpendicular to each other. The material handling device 2 can move up and down along the third direction to grab the steel bar 100 from the second set of chain platforms 12 and clamp the steel bar 100 to drive the steel bar 100 to move along the first direction to the top of the sorting device 3.

[0079] The combing device 3 includes two sets of combing components 31, which are arranged at intervals on both sides of the material taking device 2 along the second direction. The two sets of combing components 31 can move away from the material taking device 2 and comb the steel bar 100, so that the steel bar 100 is completely transferred from the flattening device 1 to the combing device 3.

[0080] The material blocking device 4 is located at the output end of the combing device 3 to receive the combed steel bars 100. The material blocking device 4 can be rotated to close to stop the steel bars 100 or rotated to open to release the steel bars 100 for feeding.

[0081] The rebar sorting and feeding equipment provided by this utility model includes a flattening device 1, a picking device 2, a sorting device 3, and a blocking device 4 arranged sequentially along a first direction on a rebar 100 production line. The picking device 2 is positioned at a high level and can move vertically. Bundles of rebar 100 are first flattened and conveyed by the flattening device 1, solving the problem of overlapping rebar 100 affecting single-bar feeding. The picking device 2 is used to grab the flattened rebar 100 and move it above the sorting device 3. Because the rebar 100 droops at both ends due to gravity during grabbing and moving, i.e., bending deformation, it is necessary to… The steel bars 100 need to be combed before being fed. The two sets of combing components 31 of the combing device 3 move away from the material taking device 2 on both sides below the material taking device 2 to comb the steel bars 100 and correct the bending deformation of the steel bars 100. At this time, the material taking device 2 releases the steel bars 100, so that the steel bars 100 are completely transferred from the flattening device 1 to the combing device 3. The output end of the combing device 3 is automatically controlled by the material blocking device 4 to cut off the steel bars 100 and feed them, thereby realizing the continuous automatic combing and feeding of the steel bars 100. It has the advantages of high automation, low labor intensity, safety and reliability, and high production efficiency.

[0082] In some embodiments, the leveling device 1 further includes a leveling base 13 and a drive shaft. The leveling base 13 is provided with a first support beam 131 and a second support beam 132 spaced apart along a first direction. The drive shaft includes a first drive shaft 14 and a second drive shaft 15, which are spaced apart along the first direction between the first support beam 131 and the second support beam 132. The first drive shaft 14 is located between the second support beam 132 and the second drive shaft 15. The first set of chain platforms 11 includes a plurality of first chain drive assemblies, with both ends of the plurality of first chain drive assemblies rotatably connected to the first support beam 131 and the first drive shaft 14, respectively. The second set of chain platforms 12 includes a plurality of second chain drive assemblies, with both ends of the plurality of second chain drive assemblies rotatably connected to the second support beam 132 and the second drive shaft 15, respectively.

[0083] like Figure 2 and Figure 8 In the illustrated embodiment, the first set of chain platforms 11 includes six first chain drive assemblies spaced apart along a second direction to support and transport the reinforcing bars 100, and the second set of chain platforms 12 includes six second chain drive assemblies spaced apart along a second direction to support and transport the reinforcing bars 100. The first set of chain platforms 11 and the second set of chain platforms 12 form an interlaced area between the first drive shaft 14 and the second drive shaft 15. When the reinforcing bars 100 are transported to this interlaced area, by controlling and adjusting the transport speed of the first set of chain platforms 11 and the second set of chain platforms 12 or changing the transport direction (one transports forward, the other backward), the reinforcing bars 100 are flattened. Figure 5As shown, for ease of design and explanation, the first set of chain platforms 11 and the second set of chain platforms 12 adopt the same structure, differing only in length and placement. Taking the first set of chain platforms 11 as an example, the six first chain drive assemblies have the same structure. Each first chain drive assembly includes a flattening drive component 111 and a first motor sprocket 112 located at the output end of the flattening drive component 111. A first transmission sprocket 113 is fixedly mounted on the first drive shaft 14. The first motor sprocket 112 and the first transmission sprocket 113 are connected by a first transmission chain 114, thereby transmitting the output power of the flattening drive component 111 to the rotation of the first drive shaft 14. Multiple conveying sprockets 115 are paired on the first drive shaft 14 and the first support beam 131. A conveying chain 117 is connected to each pair of conveying sprockets 115, thereby enabling the multiple first chain drive assemblies to rotate synchronously to convey the reinforcing bars 100. It is understood that of the two conveyor sprockets 115, one is fixedly connected to the first drive shaft 14 as the driving sprocket, and the other is rotatably connected to the first support beam 131 as the driven sprocket.

[0084] In some embodiments, the material handling device 2 includes a crossbeam 21, a transverse frame 22, a transverse drive 23, a clamping assembly 24, and a material handling assembly 25, wherein the crossbeam 21 is positioned above the leveling device 1 and the combing device 3 in a third-order direction; so that the material handling device 2 can move from above the leveling device 1 to above the combing device 3 after grabbing and clamping the reinforcing bar 100. The transverse frame 22 is slidably connected to the crossbeam 21, and the sliding direction is along the first direction; the transverse drive 23 is disposed on the crossbeam 21, and the output end of the transverse drive 23 is connected to the transverse frame 22 to drive the transverse frame 22 to slide along the first direction; the clamping assembly 24 includes a clamping drive 241 and a plurality of clamping arms 242, the plurality of clamping arms 242 are arranged in pairs and rotatably connected to the transverse frame 22 respectively, the output end of the clamping drive 241 is connected to the two clamping arms 242 of each pair and can drive the two clamping arms 242 to rotate simultaneously to close or rotate open to clamp or release the steel bar 100; the material picking assembly 25 includes a material picking drive 251 and a material picking element 252, the material picking drive 251 is disposed on the transverse frame 22, the output end of the material picking drive 251 is connected to the material picking element 252, and the material picking drive 251 is used to drive the material picking element 252 to move up and down along the third direction.

[0085] With the above structure, during material handling, the material handling component 25 moves above the leveling device 1. The material handling drive component 251 drives the material handling component 252 to move downwards and contact the reinforcing bar 100, then grabs one reinforcing bar 100 and moves it upwards until the reinforcing bar 100 contacts the clamping component 24. Then, the clamping drive component 241 drives the clamping arm 242 to rotate and close, clamping the reinforcing bar 100. Then, the lateral movement drive component 23 drives the lateral movement frame 22 to move, thereby driving the material handling component 25 and the clamping component on the lateral movement frame 22 to move synchronously, moving the clamping position of the reinforcing bar 100 above the combing device 3, so that the combing device 3 can comb the reinforcing bar 100 and meet the feeding requirements. Preferably, the lateral movement drive component 23, the clamping drive component, and the material handling drive component 251 all adopt linear drive mechanisms, such as cylinders, hydraulic cylinders, or linear motors.

[0086] In some embodiments, the material handling assembly 25 further includes a guide seat 253 and a first guide shaft 254. The output end of the material handling drive 251 is connected to the guide seat 253, and the material handling component 252 is elastically mounted on the guide seat 253. The top end of the first guide shaft 254 is fixedly connected to the transverse frame 22, and the bottom end of the first guide shaft 254 passes through the guide seat 253. The guide seat 253 can move up and down along the first guide shaft 254.

[0087] like Figure 9 and Figure 10 As shown, the function of the first guide shaft 254 is to guide the lifting and lowering movements of the material-picking drive 251 and the guide seat 253. Therefore, the first guide shaft 254 can be a linear bearing. Two first guide shafts 254 are provided, respectively located on both sides of the material-picking drive 251, which helps ensure the stability of the lifting and lowering movements of the guide seat 253. It can be understood that the bottom end of the first guide shaft 254 is fixedly connected to the guide seat 253, and the top end is slidably connected to the body of the material-picking drive 251 or the transverse frame 22, which can also achieve the same guiding effect, such as... Figure 10 The bottom end of the first guide shaft 254 is fixedly connected to the guide seat 253. A guide sleeve 255 is provided on the transverse frame 22. The first guide shaft 254 passes through the guide sleeve 255 to slide and connect to the transverse frame 22. When the material picking drive 251 drives the guide seat 253 to move up and down, the first guide shaft 254 slides in the guide sleeve 255 to achieve guidance.

[0088] In some embodiments, the material picking member 252 includes a material picking rod 2521, a fixed seat 2522, and an elastic member 2523. The top end of the material picking rod 2521 passes through the guide seat 253 and is limited to the top surface of the guide seat 253 by a limiting member 2525. The fixed seat 2522 is connected to the bottom end of the material picking rod 2521, and a magnet 2524 is provided on the fixed seat 2522 for magnetically attracting the steel bar 100. The elastic member 2523 is sleeved on the material picking rod 2521, and the two ends of the elastic member 2523 abut against the guide seat 253 and the fixed seat 2522 respectively. Under the action of the elastic force of the elastic member 2523 and the gravity of the fixed seat 2522, the top end of the material picking rod 2521 is limited to the top surface of the guide seat 253.

[0089] like Figure 9 As shown, in this embodiment, the material-picking component 25 is located inside the transverse frame 22, and the clamping component 24 is located on the side wall of the transverse frame 22. The material-picking component 252 rises after the magnetically attracted steel bar 100, so that the clamping arms 242 on both sides of the transverse frame 22 can clamp the steel bars 100 on both sides. Since the steel bar 100 undergoes a certain bending deformation under the action of gravity, in this embodiment, the transverse frame 22 is designed as a hollow structure, so that the material-picking component 252 can rise to a position higher than the two clamping arms 242 after the magnetically attracted steel bar 100, so that the clamping arms 242 can contact and clamp the steel bar 100. The elastic element 2523 is a spring, sleeved on the picking rod 2521. Two picking rods 2521 are spaced apart. The top of the picking rod 2521 is slidably installed with the guide seat 253. Under the gravity of the steel bar 100, the top of the picking rod 2521 is limited to the top surface of the guide seat 253. When the steel bar 100 is magnetically attracted, the fixing seat 2522 descends to contact the steel bar 100 and is buffered by the elastic element 2523, avoiding damage caused by hard contact magnetic attraction. In some embodiments, the limiting element 2525 can be a nut. An external thread is provided on the top of the picking rod 2521 to connect the nut, so as to adjust the position of the magnet 2524, so that the picking assembly 25 and the clamping assembly 24 can be adjusted to cooperate in the operation.

[0090] In some embodiments, the material handling device 2 further includes a second guide shaft 26, which is fixedly connected to the crossbeam 21, and the transverse frame 22 is slidably connected to the second guide shaft 26. Preferably, the second guide shaft 26 also cooperates with a guide sleeve 255 to achieve sliding guidance. Here, the guide sleeve 255 is disposed on the transverse frame 22, and the second guide shaft 26 is symmetrically arranged on both sides of the transverse drive member 23 for guidance.

[0091] In some embodiments, the combing device 3 further includes a combing frame 32, combing drive members 33, combing transmission mechanisms 34, and third chain transmission components 35. Two combing drive members 33 are provided, spaced apart on the combing frame 32 along a second direction, and respectively located on both sides of the material taking device 2 along the second direction. Two combing transmission mechanisms 34 are provided, each located at the output end of one of the two combing drive members 33. Two third chain transmission components 35 are provided, with both ends rotatably connected to the combing frame 32, and the drive ends of each third chain transmission component 35 are driven and connected to the output ends of the two combing transmission mechanisms 34. Two sets of combing members 31 are fixedly connected to the two third chain transmission components 35. The two combing drive members 33 drive the two third chain transmission components 35 in opposite directions via the two combing transmission mechanisms 34, causing the two sets of combing members 31 to move away from the material taking device 2.

[0092] like Figure 4 As shown, two sets of combing components 31 are symmetrically arranged on the combing frame 32. In this embodiment, each set of combing components 31 includes six combing components 31. The two sets of combing components 31 are driven by the combing drive component 33, the combing transmission mechanism 34, and the third chain transmission assembly 35, respectively. The two sets of combing components 31 on both sides move horizontally from the middle to both sides along the second direction, combing the two sides of the steel bar 100 clamped on the material taking device 2, so that the bent and drooping part of the steel bar 100 can also be completely transferred to the combing device 3. It can be understood that the length of the third chain transmission assembly 35 on both sides must meet the support requirements of the length of the steel bar 100.

[0093] The combing drive component 33 employs a rotary drive mechanism, such as a geared motor, to output rotational motion. The output end of the combing drive component 33 is equipped with a second motor sprocket 331, which is connected to the combing transmission mechanism 34 via a second transmission chain 332. Figure 7 As shown, the combing transmission mechanism 34 includes a second transmission sprocket 341, a combing main shaft 342, and a combing sprocket 343. The second transmission sprocket 341 is connected to the second motor sprocket 331 via a second transmission chain 332, realizing the transmission output of the combing drive component 33. The second transmission sprocket 341 is fixed on the combing main shaft 342, and the combing sprocket 343 is fixed on the combing main shaft 342. The combing main shaft 342 realizes synchronous rotation transmission between the combing sprocket 343 and the second transmission sprocket 341. The combing sprocket 343 is connected to the third chain transmission assembly 35 via a combing chain 344 (e.g., ...). Figure 4 Furthermore, such as Figure 7As shown, the combing spindle 342 is rotatably supported on the combing frame 32 by two bearings (with vertical bearing 345), and the combing sprocket 343 is fixed on the combing spindle 342 between the two bearings. The combing sprocket 343 is isolated and positioned by the shaft diameter on the combing spindle 342 and the spacer 346 set between it and the second transmission sprocket.

[0094] like Figure 6 As shown, the third chain drive assembly 35 includes a first tensioning bracket 351, a first tensioning wheel 352, and a bearing guide rail. The first tensioning bracket 351 is fixed on the carding frame 32. The carding tensioning wheel is rotatably connected to the carding frame 32 via the carding shaft 354. The first tensioning wheel 352 is connected to the carding sprocket 343 (as shown in the image). Figure 4 The carding sprocket 343 is connected to the drive chain to achieve the drive connection. A bearing circular guide rail is located on the outer periphery of the carding sprocket 343 to support the carding component 31 and the reinforcing bar 100. The carding component 31 is connected to the carding chain 344 and slides on the bearing circular guide rail. Preferably, the carding component 31 and the bearing circular guide rail are connected by a bolt-type roller needle bearing 355. Figure 6 As shown, the first tensioning bracket 351 is connected to two connecting rods of the carding frame 32. Bolts are provided on both sides of the first tensioning bracket 351 on the two connecting rods. The position between the first tensioning bracket 351 and the carding frame 32 can be adjusted by adjusting the position of the bolts on the connecting rods.

[0095] In some embodiments, the combing device 3 further includes a combing tensioning component 36, which is mounted on the combing frame 32 in an adjustable position and can tension the third chain drive component 35 in a third direction.

[0096] like Figure 4 As shown, multiple carding tensioning components 36 are provided, and these components are spaced apart along the second direction to adjust the tension of the carding chain 344. Figure 8 As shown, the carding tensioning assembly 36 includes a second tensioning bracket 361 and a second tensioning wheel 362. The second tensioning bracket 361 is adjustablely mounted on the carding frame 32. Specifically, the second tensioning bracket 361 is connected to the carding frame 32 by a long bolt, and multiple nuts are threaded onto the long bolt. The position of the second tensioning bracket 361 is adjusted and locked by bolts on both sides to achieve positional adjustment. The second tensioning wheel 362 is rotatably connected to the second tensioning bracket 361 via a pin 363. The second tensioning wheel 362 drives the carding chain 344 to achieve tension adjustment of the carding chain 344. Preferably, a sleeve 364 is provided between the second tensioning wheel 362 and the pin 363 for isolation and positioning.

[0097] In some embodiments, the combing member 31 includes a connecting portion 311 and a combing portion 312. The connecting portion 311 is fixedly connected to the third chain drive assembly 35. The combing portion 312 is fixedly connected to one end of the connecting portion 311 facing the flattening device 1. The combing portion 312 is provided protruding from the surface of the connecting portion 311 and is able to contact the reinforcing bar 100 to comb the reinforcing bar 100.

[0098] like Figure 8 As shown, the combing component 31 is generally configured as an L-shaped hook structure. The combing part 312 of the combing component 31 is a structure that protrudes from the conveying plane of the combing chain 344, so that the part of the steel bar 100 located above the combing chain 344 can contact the combing part 312 when the material taking device 2 is in a suitable position. The combing parts 312 on both sides move away from each other, and the steel bar 100 is gradually combed onto the combing device 3. That is, the two ends of the steel bar 100 are transferred to the combing device 3 under the action of the combing part 312. It can be understood that the height setting of the combing part 312 takes into account the distance between the steel bar 100 on the material taking device 2 and the combing device 3.

[0099] In some embodiments, the connecting portion 311 is inclined downwards at the end away from the leveling device 1, and the combing frame 32 is provided with an inclined guide portion 321. The connecting portion 311 and the guide portion 321 are sequentially connected to continuously convey the reinforcing bar 100. Figure 8 As shown, the connecting part 311 of the combing component 31 and the conveying plane of the combing chain 344 have a certain inclination angle. When the reinforcing bar 100 is transferred to the combing device 3 under the action of the combing part 312, due to the inclination of the connecting part 311, the reinforcing bar 100 can automatically slide down under its own weight for collection, stopping at the retaining device 4. According to the processing of the combing frame 32 and the setting space of the retaining device 4, in order to ensure the smooth sliding of the reinforcing bar 100, a guide part 321 is provided on the combing frame 32. The guide part 321 is inclined downward to facilitate the further sliding of the reinforcing bar 100. The guide part 321 and the connecting part 311 can have the same inclination angle, or the guide part 321 can have a larger inclination angle so that the reinforcing bar 100 can slide down and be collected at the retaining device 4 more quickly.

[0100] In some embodiments, the combing device 3 further includes a support member 37, which is disposed on the third chain drive assembly 35 and spaced apart from the combing member 31. The support member 37, the combing member 31 and the guide part 321 have the same tilt angle so that the reinforcing bar 100 can slide downward under its own weight.

[0101] Combination Figure 4 and Figure 8Multiple support members 37 are provided and are mounted on two sets of third chain drive assemblies 35 to support and protect the combing chain 344. The main body structure of the support member 37 is the same as that of the connecting part 311 of the combing member 31, and it is inclinedly mounted on the combing chain 344. The difference lies in the bending direction of the two ends of the support member 37. In the combing member 31, the combing part 312 bends the higher end of the connecting part 311 upwards to comb the reinforcing bar 100; both ends of the support member 37 are bent downwards relative to the combing chain 344. The downward bending of the higher end avoids obstructing the reinforcing bar 100, while the downward bending of the lower end facilitates the connection with the guide part 321 to achieve a transition connection.

[0102] In some embodiments, the material blocking device 4 includes a material blocking drive 41, a linkage plate 42, a rotating plate 43, and a receiving arm 44. The material blocking drive 41 is mounted on the carding frame 32. The linkage plate 42 is movably connected to the output end of the material blocking drive 41 and extends along a second direction. Multiple rotating plates 43 are provided, and the multiple rotating plates 43 are spaced apart along the second direction on the linkage plate 42 and rotatably connected to the linkage plate 42. The carding frame 32 is provided with a rotating shaft, and the two ends of the rotating shaft are respectively rotatably connected to the receiving arm 44 and the rotating plate 43. The extension and retraction movement of the material blocking drive 41 can drive the linkage plate 42 to move along the second direction and drive the receiving arm 44 to rotate open or rotate close through the rotating plate 43.

[0103] Applying the steel bar sorting and feeding equipment provided by this utility model, combined with Figures 11-19 The method for sorting and feeding reinforcing bars includes the following steps:

[0104] S1, place the whole bundle of steel bars 100 on the flattening device 1 for unbundling and conveying, and convey multiple steel bars 100 to the bottom of the material taking device 2 and flatten them;

[0105] like Figure 11 As shown, bundles of steel bars 100 can be placed onto the first set of chain platforms 11 of the leveling device 1 via an overhead crane or other lifting equipment, and then broken into smaller bundles. The leveling device 1 is then activated, and the steel bars 100 are conveyed towards the material handling device 2 in the first direction. When a portion of the steel bars 100 have been conveyed to the first set of chain platforms 11, the conveying of steel bars 100 by the first set of chain platforms 11 is stopped, and the second set of chain platforms 12 continues to convey the steel bars 100 towards the material handling device 2, stopping when they reach below the material handling device 2. Figure 12 As shown.

[0106] S2, the material handling device 2 grabs and clamps the steel bar 100 to move the steel bar 100 along the first direction above the combing device 3;

[0107] Specifically:

[0108] After the flattened steel bar 100 is delivered to the designated position, the output end of the material-grabbing drive 251 extends, driving the material-grabbing component 252 to move downwards and grab (magnetically attract) the steel bar 100. Figure 13 As shown;

[0109] The output end of the material handling drive 251 retracts and drives the material handling component 252 to move the reinforcing bar 100 upward until the clamping assembly 24 can clamp the reinforcing bar 100 at a position (which can be pre-designed). Figure 14 .

[0110] The clamping drive unit 241 drives the two clamping arms 242 to move and clamp the steel bar 100, as shown. Figure 15 ;

[0111] When the lateral movement drive 23 is activated, its output end retracts, causing the entire lateral movement frame 22 to move towards the combing device 3. The middle portion of the reinforcing bar 100 that is clamped then reaches above the combing device 3. Figure 16 .

[0112] S3, the two sets of combing components 31 of the combing device 3 move away from the material taking device 2 to comb the steel bar 100 from the middle to both sides, so that the steel bar 100 is completely transferred from the flattening device 1 to the combing device 3.

[0113] If further explanation is needed, when the combing device 3 is in its initial position, such as Figures 11-15 The support member 37 is located on the side closer to the material handling device 2, thereby preventing the reinforcing bar 100 from being blocked during its movement. During the combing process, as... Figure 16 Two sets of combing components 31 move upward from the middle position of the two sets of combing transmission mechanisms 34, and two sets of third chain transmission components 35 have opposite conveying directions, so that the two sets of combing components 31 move from the middle to both sides. After multiple combing components 31 contact the steel bar 100 in sequence, they comb the steel bar 100 to the combing device 3.

[0114] S4, the material handling device 2 releases the steel bar 100, the steel bar 100 falls onto the sorting device 3 and slides to the material blocking device 4 to prepare for feeding;

[0115] like Figure 17 The clamping drive 241 drives the two clamping arms 242 to rotate and open, releasing the reinforcing bar 100 onto the combing device 3. After release, the reinforcing bar 100 slides downward from one side of the combing section 312 along the connecting section 311 under the action of the combing component 31; as the combing component 31 rotates again to below the combing chain 344 (referring to the upper conveying plane of the combing chain 344), the support component 37 rotates to above the combing chain 344, and the reinforcing bar 100 slides from top to bottom, stopping at the stop device 4 when passing the guide section 321. Figure 18 .

[0116] After releasing the reinforcing bar 100, the clamping drive 241 drives the two clamping arms 242 to rotate and partially close, returning to the initial state (e.g., Figure 18 This allows for the next clamping of the reinforcing bar 100. The output end of the transverse drive 23 extends and feeds the entire material handling device 2 above the leveling device 1, resetting it to its initial state to facilitate the handling of the next reinforcing bar 100.

[0117] S5, the material blocking device 4 rotates and opens, and the steel bar 100 slides to the next process under the action of gravity to realize the feeding;

[0118] like Figure 19 When the material blocking device 4 starts, the material blocking drive 41 is activated, and multiple material receiving arms 44 rotate and open synchronously. The steel bar 100 slides down to the next process under its own gravity, thus realizing the feeding of the steel bar 100.

[0119] S6. Repeat steps S2-S5 to complete the loading of the entire bundle of steel bars 100.

[0120] The above-mentioned rebar sorting and feeding method, using the rebar sorting and feeding equipment provided by this utility model, realizes continuous automatic sorting and feeding of rebar 100, effectively reducing the labor intensity of workers on the production line. The rebar 100 feeding process is safe and reliable, and the production efficiency is high.

[0121] In step S1, the flattening process of the multiple reinforcing bars 100 is as follows:

[0122] When the reinforcing bar 100 is conveyed along the first set of chain platforms 11 to the intersection area of ​​the first set of chain platforms 11 and the second set of chain platforms 12, the first set of chain platforms 11 and the second set of chain platforms 12 convey the reinforcing bar 100 forward and backward respectively in the conveying direction until the reinforcing bar 100 is flattened.

[0123] Repeat the action of conveying the steel bars 100 forward and backward on the first set of chain platforms 11 and the second set of chain platforms 12 until the steel bars 100 below the material handling device 2 are flattened.

[0124] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
