[0025] Example

[0026] like Figure 1-Figure 3 As shown, this embodiment includes a feeding mechanism for placing bundled steel bars and dispersing the bundled steel bars, and a taking mechanism arranged at one end of the feeding mechanism and capable of taking out the steel bars one by one. The feeding mechanism includes a feeding base 11, a feeding rack 13 flexibly connected to the feeding base 11 through a spring limiter 12, and a plurality of mounting cross bars 14 equidistantly arranged on the feeding rack 13. A limiting rod 15 is vertically fixed on each mounting cross bar 14, and the limiting rod 15 divides the upper part of the mounting cross bar 14 into two lower hanging bar bins 16 and an upper hanging bar bin 17 located between the lower hanging bar bins 16. The lower hanging bar bins 16 separated and connected on all the mounting cross bars 14 are connected together to correspond to the length of the bundled steel bars to be placed, and the same is true for the upper hanging bar bins 17. An upper reinforcement silo 17 is provided with an upper reinforcement roller 18 fixed to the side of the mounting cross bar 14 close to the material-removing mechanism, and a lower reinforcement roller 19 is provided in the lower reinforcement silo 16, which is fixed to the side of the mounting cross bar 14 away from the material-removing mechanism. The upper reinforcement roller 18 and the lower reinforcement roller 19 both support the reinforcement and reduce the friction of the reinforcement during movement.

[0027] like Figure 1-Figure 3 As shown, a vibration device 10 is provided at the bottom of the feeding rack 13. The vibration device 10 can vibrate the feeding rack 13 relative to the feeding base 11 through different frequencies, and vibrate all the bundled steel bars placed in the silo to a certain extent, so as to achieve the purpose of dispersing the steel bars, and make a small number of steel bars move from the bundled steel bars toward the feeding mechanism until the front ends of these steel bars enter the feeding mechanism. In addition, the feeding rack 13 is arranged at an angle, and the horizontal height of the end of the feeding rack 13 close to the feeding mechanism is lower than that of the end of the feeding rack 13 away from the feeding mechanism. The feeding rack 13 in the inclined state cooperates with the vibration device 10 to accelerate the loosening process of the bundled steel bars. In this embodiment, the angle between the feeding rack 13 and the horizontal plane is 3.5 degrees.

[0028] like Figure 1-Figure 2 , Figure 4-Figure 7As shown, the material taking mechanism includes a material taking base 21, two lower hanging bar material taking troughs 22 separated by a partition 20 and arranged on the material taking base 21, and an upper hanging bar material taking trough 23 located between the lower hanging bar material taking troughs 22, the upper hanging bar material taking trough 23 corresponds to the upper hanging bar material bin 17, and the lower hanging bar material taking troughs 22 on both sides of the upper hanging bar material taking trough 23 correspond to the lower hanging bar material bins 16 on both sides of the upper hanging bar material bin 17. A fixing frame 24 located above the lower hanging bar material taking trough 22 is fixed on the material taking base 21, and a group of lower hanging bar material taking devices 25 corresponding to the two lower hanging bar material taking troughs 22 are arranged on the fixing frame 24, and each lower hanging bar material taking device 25 can be used to grab the steel bars entering its corresponding lower hanging bar material bin 16 and transfer the steel bars. The lower hanging bar picking device 25 includes a transverse driving cylinder 26 fixed on the fixed frame 24, a first lifting cylinder 27 arranged at one end of the transverse driving cylinder 26 and capable of transverse movement under the drive of the transverse driving cylinder 26, and a magnetic gripper 28 arranged at the lower end of the first lifting cylinder 27. The magnetic gripper 28 can move transversely under the drive of the transverse driving cylinder 26 and move vertically under the drive of the first lifting cylinder 27 to achieve the grasping and transfer of the steel bars. The picking base 21 is provided with a mounting platform 29 located at one end of the upper hanging bar picking trough 23 away from the feeding mechanism. The mounting platform 29 is provided with a pair of lower hanging bar clamping wheels 30 corresponding to the lower hanging bar picking device 25. When the magnetic gripper 28 grabs the steel bar, it will transfer the steel bar through the transverse driving cylinder 26 and the first lifting cylinder 27 until the front end of the steel bar enters the corresponding lower hanging bar clamping wheel 30, and then the magnetic gripper 28 releases the steel bar, and the steel bar continues to move forward under the drive of the lower hanging bar clamping wheel 30. A pair of limiting holes 31 are provided at one end of the mounting platform 29 away from the feeding mechanism, and the limiting holes 31 correspond to the positions of the lower hanging bar clamping wheels 30. The steel bars driven by the lower hanging bar clamping wheels 30 will enter the corresponding limiting holes 31 to prepare for subsequent processing.

[0029] like Figure 1-Figure 2 , Figure 4-Figure 7As shown, an upper bar rack 32 is provided in the middle of the fixed frame 24, and an upper bar picking device 33 is provided on the upper bar rack 32, which is located just above the upper bar picking trough 23. The upper bar picking device 33 is used to grab the steel bars entering the upper bar bin 17 and transfer the steel bars. The upper bar picking device 33 includes a second lifting cylinder 34 fixed to one end of the upper bar rack 32 close to the feeding mechanism and located just above the upper bar picking trough 23, and a magnetic gripper 28 provided at the lower end of the second lifting cylinder 34. The magnetic gripper 28 can move vertically under the drive of the second lifting cylinder 34 to achieve the grabbing and lifting height of the steel bars. An upper-hanging-bar clamping wheel 35 corresponding to the upper-hanging-bar taking device 33 is provided at the bottom of the upper-hanging-bar frame 32. When the magnetic claw 28 grabs the steel bar, the steel bar will be transferred through the second lifting cylinder 34 until the front end of the steel bar enters the upper-hanging-bar clamping wheel 35. Then the magnetic claw 28 releases the steel bar, and the steel bar continues to move forward driven by the upper-hanging-bar clamping wheel 35.

[0030] like Figure 1-Figure 3 As shown, the lower rib roller 19 is tilted, and on the same mounting cross bar 14, the lower rib roller 19 is closer to one end of the upper rib roller 18 than the other end. Specifically, when the feeding rack 13 vibrates with the vibration device 10, the steel bars in the lower rib bin 16 will move toward the upper rib roller 18 along with the tilted lower rib roller 19 until they reach the preset corresponding lower rib retrieval trough 22. The middle diameter of the upper rib roller 18 is smaller than the diameters at both ends of the upper rib roller 18, and the middle position of the upper rib roller 18 corresponds to the upper rib retrieval device 33. Specifically, when the feeding rack 13 vibrates with the vibration device 10, the steel bars in the upper rib bin 17 will move to the middle of the upper rib roller 18, that is, the preset corresponding upper rib retrieval trough 23.
