[0023] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0024] like Figure 1 As shown, an automatic steel bar cutting device in one embodiment of the present invention includes a frame 1, a cutting table 2, a cutting machine 3, an intermittent feeding mechanism 4, a traction assembly 5 and a blanking assembly 6. The cutting table 2 is horizontally mounted on the frame 1, one end of the cutting table 2 is connected to the discharge port of the intermittent feeding mechanism 4, and a avoidance groove 21 for the cutting knife of the cutting machine 3 to extend into is provided on the cutting table 2; the cutting machine 3 is mounted on the frame 1 and is located on one side of the cutting table 2, the cutting knife of the cutting machine 3 is facing the avoidance groove 21, and the frame 1 is equipped with a device for driving the cutting machine 3 toward the near Or the first drive component 11 moves away from the avoidance groove 21. The first drive component 11 is a screw motor module. The screw motor module belongs to the existing technology and will not be described in detail here. The cutting machine 3 is fixedly mounted on the moving seat of the screw motor module. There are multiple steel bars 101 stacked in the intermittent feeding mechanism 4, and the intermittent feeding mechanism 4 is used to feed the steel bars 101 one by one. The traction component 5 is used to pull the steel bars 101 at the discharge port of the intermittent feeding mechanism 4 to the cutting table 2; the unloading component 6 is used to unload the cut steel bars 101 from the cutting table 2.

[0025] According to the needs of the construction personnel, the intermittent feeding mechanism 4 transports the steel bars 101 out one by one, then the traction assembly 5 pulls the steel bars 101 at the discharge port of the intermittent feeding mechanism 4 to the cutting table 2, then the cutting machine 3 and the first driving assembly 11 are started at the same time, the cutting machine 3 is driven to move towards the position close to the avoidance groove 21 until the cutting knife of the cutting machine 3 completes cutting on the steel bar 101 and resets, and finally the cut steel bar 101 is unloaded from the cutting table 2 by the unloading assembly 6. If the steel bar 101 needs to be cut again, the traction assembly 5 is used to pull the steel bar 101 to the next cutting position for cutting, and the excess part of the single steel bar 101 can also be unloaded from the cutting table 2 by the unloading assembly 6.

[0026] As shown in Figure 2 and Figure 3 , the intermittent feeding mechanism 4 includes a collecting box 41, a feeding cylinder 42, a pair of limiting plates 43 and a first driving member 44. The bottom of the collecting box 41 extends downward and downward. A discharge port 411 is formed in the lower side of the bottom of the collecting box 41, so that the steel bars 101 in the collecting box 41 can freely slide into the discharge port 411. The feeding cylinder 42 extends horizontally and is rotatably installed below the discharge port. The feeding cylinder 42 is provided with a plurality of clamping grooves 421 for clamping a single steel bar 101. One side of the feeding cylinder 42 is provided with a discharge groove 45, and one end of the discharge groove 45 is communicated with the cutting table 2. The first driving member 44 is used to drive the feeding cylinder 42 to rotate. The first driving member 44 is a motor, and the output shaft of the first driving member 44 is connected with the rotating shaft of the feeding cylinder 42 through a belt transmission module. The two limiting plates 43 are arranged on the two sides of the feeding cylinder 42. The limiting plates 43 are arc-shaped plates parallel to the outer side walls of the feeding cylinder 42. The gap between the top portions of the two limiting plates 43 corresponds to the clamping grooves 421 at the top of the feeding cylinder 42. The intermittent feeding mechanism 4 further includes a limiting assembly 7 for limiting the steel bars 101 to enter the clamping grooves 421 one by one from the discharge port 411.

[0027] The steel bars 101 entering the discharge port 411 are limited by the limiting assembly 7 to enter the clamping grooves 421 one by one through the gap between the top portions of the two limiting plates 43. Then the feeding cylinder 42 is driven to rotate by the first driving member 44. When the clamping groove 421 with the steel bar 101 rotates downward, the steel bar 101 falls into the discharge groove 45 and is taken away by the traction assembly 5. The limiting plates 43 limit the steel bars 101 in the clamping grooves 421 before they are rotated downward. This process can stably achieve one-by-one feeding with high efficiency.

[0028] Further, as shown in Figure 3 and Figure 4As shown, the limiting assembly 7 includes a pair of clamping plates 71 and a pair of second driving members 72. The two clamping plates 71 are arranged in a vertical direction and are arranged on the extension path of the discharging port 411. The spacing between the two clamping plates 71 is only for accommodating a single steel bar 101. The two second driving members 72 are respectively used to drive the two clamping plates 71 to move in a horizontal direction. The second driving member 72 is a pneumatic cylinder. The piston rods of the two second driving members 72 are respectively fixedly connected to the two clamping plates 71. Thus, the two clamping plates 71 are first driven to move to a position above the gap between the top portions of the two limiting plates 43, and then the upper clamping plate 71 is driven to move away from the lower clamping plate 71, so that a steel bar 101 falls on the lower clamping plate 71. Then, the upper clamping plate 71 is driven to reset, so that the steel bar 101 is located between the two clamping plates 71. Subsequently, only the lower clamping plate 71 needs to be driven to move away from the position above the gap between the top portions of the two limiting plates 43, so that the steel bar 101 can be smoothly fed into the feeding cylinder 42.

[0029] As shown in Figure 2 and Figure 5 , the bottom of the collecting box 41 and the position close to the discharging port 411 are provided with a dredging assembly 8. The dredging assembly 8 includes a pair of swing rods 81 and a third driving member 82. The two swing rods 81 are respectively located on both sides of the bottom of the collecting box 41. The swing rods 81 are parallel to the bottom of the collecting box 41 and are rotatably installed on the bottom of the collecting box 41. The third driving member 82 is used to drive the end of the swing rod 81 close to the discharging port 411 to be raised. The third driving member 82 is a pneumatic cylinder. The piston rod of the third driving member 82 is hingedly connected to the end of the swing rod 81 away from the discharging port 411. Thus, when the steel bar 101 is blocked at the discharging port 411, the third driving member 82 is started to drive the swing rod 81 to be raised to push the steel bar 101, so as to achieve the purpose of dredging.

[0030] As shown in Figure 1 , Figure 6 , Figure 7 and Figure 8 , the cutting table 2 includes two pairs of baffles 22. The two pairs of baffles 22 are horizontally and oppositely arranged. The two pairs of baffles 22 are correspondingly arranged. The two baffles 22 corresponding to each other are both inclined to each other towards the bottom. Thus, the steel bar 101 can be clamped between the two baffles 22. The gap between the two baffles 22 of the same pair forms an avoiding groove 21.

[0031] The traction assembly 5 comprises a fourth driving member 51, a mounting plate 52, an electric clamp jaw 53 and a second driving assembly 54. The fourth driving member 51 is used to extend the steel bars 101 in the discharge chute 45 out of the intermittent feeding mechanism 4 close to one end of the cutting table 2. The fourth driving member 51 is a pneumatic cylinder. The piston rod of the fourth driving member 51 is opposite to the end of the discharge chute 45 away from the cutting table 2, so that the steel bars 101 in the discharge chute 45 can be extended out of the intermittent feeding mechanism 4 close to one end of the cutting table 2. The mounting plate 52 is slidingly mounted between the two pairs of baffle plates 22 in the extension direction of the cutting table 2. The second driving assembly 54 is used to drive the mounting plate 52 to slide. The second driving assembly 54 is a lead screw motor module, which is a prior art and will not be described here. The electric clamp jaw 53 is fixedly installed on the mounting plate 52, and the clamp jaw of the electric clamp jaw 53 faces the intermittent feeding mechanism 4.

[0032] Therefore, the electric clamp jaw 53 can be driven by the second driving assembly 54 to move to the discharge port of the intermittent feeding mechanism 4. The electric clamp jaw 53 can clamp the end of the steel bars 101 extended out of the intermittent feeding mechanism 4. The electric clamp jaw 53 can be driven by the second driving assembly 54 to move away from the intermittent feeding mechanism 4, so that the steel bars 101 can be pulled onto the cutting table 2, and the automatic feeding is completed.

[0033] Furthermore, as shown in Figure 6 , Figure 7 and Figure 9 , a pair of mounting racks 12 are arranged on the rack 1. The two mounting racks 12 are respectively arranged on the two sides of the avoidance groove 21. A limiting pneumatic cylinder 13 is fixedly installed on the mounting rack 12. The piston rod of the limiting pneumatic cylinder 13 is vertically downwardly arranged. A pressing block 14 is fixedly installed on the piston rod of the limiting pneumatic cylinder 13. The pressing block 14 is located directly above the cutting table 2, so that the steel bars 101 can be limited on the two sides of the avoidance groove 21 before cutting, and the cutting is more smooth.

[0034] As shown in Figure 1 , Figure 6 , Figure 7 and Figure 8 , one of the baffle plates 22 away from the intermittent feeding mechanism 4 is a discharging plate 23. The bottom of the discharging plate 23 is hingedly connected to the rack 1. A discharging assembly 6 comprises a fifth driving member 61, a guide plate 62, a plurality of collecting boxes 63 and a sixth driving member 64. The fifth driving member 61 is used to drive the discharging plate 23 to rotate. The fifth driving member 61 is an electric motor. The fifth driving member 61 is fixedly installed on the rack 1. The rotating shaft of the fifth driving member 61 is fixedly connected to the rotating shaft of the discharging plate 23. A pushing pneumatic cylinder 24 is fixedly installed on the baffle plate 22 opposite to the discharging plate 23. The piston rod of the pushing pneumatic cylinder 24 is opposite to the discharging plate 23. When the fifth driving member 61 drives the discharging plate 23 to rotate away, the steel bars 101 cut out can be pushed away from the cutting table 2 by starting the pushing pneumatic cylinder 24.

[0035] The guide plate 62 is inclined downward from directly below the discharging plate 23 in a direction away from the discharging plate 23; a plurality of collection boxes 63 are arranged in the extension direction of the cutting table 2, one of which is located directly below the lower side of the guide plate 62; a slide rail 65 is arranged at a position directly below each collection box 63, and a sixth driving member 64 is used to push each collection box 63 to move in the arrangement direction, the sixth driving member 64 being a pneumatic cylinder, and the piston rod of the sixth driving member 64 abutting against the outer wall of the collection box 63 at the tail end; after the cut steel bars 101 are pushed out from the discharging plate 23, they slide into the corresponding collection box 63 through the guide plate 62, and when the demand of a construction worker for steel bars 101 is completed, the sixth driving member 64 is started to push the collection box 63 at the tail end, so that the next empty collection box 63 is directly opposite the position directly below the lower side of the guide plate 62, achieving automatic discharging.

[0036] The implementation principle of the automatic steel bar cutting device according to the embodiment of the application is as follows: according to the demand of a construction worker, the second driving member 72 is started to drive the upper clamping plate 71 to move away from the lower clamping plate 71, so that a steel bar 101 falls on the lower clamping plate 71, then the upper clamping plate 71 is driven to reset, so that the steel bar 101 is located between the two clamping plates 71, and then the lower clamping plate 71 is driven to move away from the position directly above the gap between the top of the two limiting plates 43, so that the steel bar 101 falls smoothly into the clamping groove 421 of the feeding cylinder 42; then the first driving member 44 is started to drive the feeding cylinder 42 until the steel bar 101 falls into the discharging groove 45; then the fourth driving member 51 is started to make the steel bar 101 in the discharging groove 45 extend out of the intermittent feeding mechanism 4.

[0037] Then the second driving assembly 54 is used to drive the electric clamping jaw 53 to move to the discharging port of the intermittent feeding mechanism 4, the electric clamping jaw 53 is used to clamp the end of the steel bar 101 extending out of the intermittent feeding mechanism 4, and then the second driving assembly 54 is used to drive the electric clamping jaw 53 to move away from the intermittent feeding mechanism 4, so that the steel bar 101 is pulled into the cutting table 2; then the cutting machine 3 and the first driving assembly 11 are started at the same time to drive the cutting machine 3 to move towards the avoidance groove 21 until the cutter of the cutting machine 3 completes cutting of the steel bar 101.

[0038] When the fifth driving member 61 is started to drive the blanking plate 23 to turn open, the push cylinder 24 is started to push the cut steel bars 101 away from the cutting table 2. After the cut steel bars 101 are pushed out from the blanking plate 23, the cut steel bars 101 slide into the corresponding collecting box 63 through the guide plate 62. When the steel bar demand of one construction worker is completed, the sixth driving member 64 is started to push the tail end collecting box 63, so that the next empty collecting box 63 is opposite to the lower side of the guide plate 62.

[0039] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made according to the structure, shape, and principle of the present application should be covered by the protection scope of the present application.

[0042] Specifically, the construction worker inputs the steel bar demand information in the terminal according to the actual situation in the construction site, for example, inputs 10cmX2, 20cmX1, 30cmX2 in the mobile phone; then sends the information to the terminal of the automatic steel bar cutting device; and then the terminal of the automatic steel bar cutting device sorts the steel bar demand information of different construction workers to form the best cutting sequence information.

[0043] S20: Trigger the cutting instruction according to the cutting sequence information.

[0047] Specifically, the camera at the construction site is used to monitor the collection box in real time, the position of the collection box corresponding to each construction worker is found, and then the position of the collection box is sent to the terminal of the corresponding construction worker in real time. The subsequent construction worker can quickly find the steel bars belonging to himself according to the position of the collection box.

[0048] In an embodiment, as shown in Figure 11 S10 specifically includes the following steps: The following steps are executed in a loop: S11: Obtain first order demand information according to steel demand information.

[0052] In this embodiment, the steel surplus information refers to the length surplus of the steel raw material after the cutting of the last steel bar in the first order demand information.

[0053] Specifically, for example, the length of a steel raw material is 150 cm, and the length information of the steel bar in the first order demand information is 30 cm X 4. The length of the steel raw material is 30 cm, that is, the steel surplus information is 30 cm.

[0054] S13: Obtain remaining demand information, and match the next order demand information according to the steel surplus information and the remaining demand information.

[0055] In this embodiment, the remaining demand information refers to the remaining demand information after the first order demand information.

[0056] Specifically, for example, the steel surplus information is 30 cm, and the next order demand information is matched in the remaining demand information if there is steel length information less than or equal to 30 cm; so that the cutting process is more reasonable, and the waste of steel bars is reduced.

[0057] S14: When all steel demand information is matched to the corresponding order demand information or the steel surplus information is less than any remaining demand information, stop the loop, and form the cutting order information according to the order of the loop demand information.

[0058] Specifically, when all the steel bar demand information is matched to the corresponding sequential demand information or the steel bar surplus information is less than any remaining demand information, it is indicated that the sorting is completed or there is no remaining demand information that can be reasonably connected to the previous sequential demand information, and thus the loop is stopped, and the cutting sequence information is formed according to the order of the loop demand information; if there is demand information after the loop is completed, the sorting is performed again according to S12-S14 to form the next cutting sequence information; if only one demand information is left after the loop is completed, the demand information is directly arranged at the end.

[0059] In an embodiment, as shown in FIG. 13, step S13 specifically includes: Figure 12 S131: If more than one item in the remaining demand information is matched to the steel bar surplus information, the demand issuing time information is obtained.

[0060] Specifically, if more than one item in the remaining demand information is matched to the steel bar surplus information, it is indicated that the length information of the steel bar in multiple remaining demand information all exists in the steel bar with a length less than or equal to the steel bar surplus information; and the corresponding demand issuing time information in each matched remaining demand information is obtained.

[0061] S132: The demand issuing time information is sorted, and the demand information with the earliest time is taken as the next sequential demand information.

[0062] Specifically, the corresponding demand issuing time information in each matched remaining demand information is sorted, and the demand information with the earliest time is taken as the next sequential demand information, so that the sorting is more fair.

[0063] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.​
