[0012] Preferably, the traveling frame is driven by a first power mechanism, and both the first power mechanism and the second power mechanism are located on the traveling frame.

[0013] The present invention also provides a working method for an automatic steel bar material handling, dispensing and feeding device, comprising the following steps:

[0014] S1, the equipment receives the material loading signal, the traveling frame moves to the designated position in the hopper, the material picking and distributing mechanism descends until the induction trigger plate senses the material, indicating that the material picking position has been reached, the suction mechanism stops descending. If the suction mechanism continues to descend and the induction trigger plate does not sense the material after descending to the limit position, it means that the hopper is empty, the system will automatically alarm and notify the manual replenishment.

[0015] S2, after the material handling and distribution mechanism descends to the material handling position, the material suction mechanism sucks up the material;

[0016] S3, after the material is sucked up, the material picking and distributing mechanism rises to the designated position, the hooking mechanism descends, and the hooking and traveling mechanism moves forward. During the rising process of the material picking and distributing mechanism, the induction trigger plate will always sense that the material picking mechanism has picked up the material. If the material falls off during the rising process, the induction trigger plate will descend and lose its sensing function, the system will alarm, and it will prompt that the material has fallen off and the material will be picked up again.

[0017] S4, after the sensor detects the material, the hooking and walking mechanism stops moving forward, the hooking mechanism rises to hook the material, the suction mechanism stops sucking the material, the excess material is removed, the suction mechanism sucks up the material hooked by the hooking mechanism again, and the material picking and distributing mechanism continues to rise to the designated position.

[0018] S5, the walking material support mechanism at both ends of the material picking and distributing mechanism rotates and extends to the working state, and the walking material support mechanism moves from the middle to both sides to lift the material.

[0019] S6, after the walking material support mechanism passes through the position of the fixed material support mechanism, the corresponding sensor detects that the walking material support mechanism has arrived in place, and the fixed material support mechanism rotates to the working position to support the material.

[0020] S7, after all the fixed material support mechanisms rotate and extend to the working position to support the material, the traveling material support mechanisms at both ends reach the designated material support position, and the traveling frame moves to the material dropping position;

[0021] S8, the hooking mechanism descends first, then the hooking walking mechanism returns to the origin, all fixed material support mechanisms rotate and retract to the waiting position, the suction mechanism stops suctioning, the two-end walking material support mechanisms continue to walk to both ends, the material falls onto the guide frame and rolls down the guide frame to the next station;

[0022] S9, all mechanisms return to the origin, and the entire workflow is repeated for the next material picking, sorting and feeding.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This invention solves the problem of automatic material handling, sorting, and feeding of stirrups on steel bar processing equipment in the field of construction engineering. The equipment has a simple operation process, is highly efficient, stable, and reliable, and can achieve 24-hour production, which greatly improves production efficiency.

[0025] 2. In this invention, the height of the hopper and the guide frame is lower than the height of the traveling frame, ensuring that the traveling frame can smoothly slide over the hopper and the guide frame, thus providing space for autonomous descent to pick up materials and descent to distribute and feed materials.

[0026] 3. When the induction trigger plate in this invention triggers the material and is lifted by the material, the proximity sensor detects the material, indicating that the material picking and distributing mechanism has reached the picking position and the suction mechanism can start to pick up the material; the induction trigger plate can determine whether the suction mechanism has successfully picked up the material throughout the entire working process; when the induction plate detects the material, it can provide feedback that the hooking walking mechanism can stop moving forward and start the hooking mechanism to rise and hook the material; thus, the entire equipment can accurately pick up the material.

[0027] 4. In this invention, there is a height difference between the walking material support mechanism and the fixed material support mechanism to enable the walking material support mechanism to pass smoothly under the fixed material support mechanism. At the same time, both the walking material support mechanism and the fixed material support mechanism can switch between rotating extension and rotating retraction working states by rotating, so as to support and avoid materials. In addition, each fixed material support mechanism can sense the passage of the walking material support mechanism in time through the setting of the sensor and rotate to the working position to support the material in time.

[0028] 5. The working method provided by this invention is simple and easy to operate, highly automated, saves labor costs, and is suitable for mass production. Attached Figure Description

[0036] The following will combine Figure 1-7 The present invention will be described in detail below. The illustrative embodiments and descriptions herein are used to explain the invention, but are not intended to limit the invention.

[0037] An automatic rebar feeding and dispensing device includes a traveling frame 1, a traveling support 3 slidably connected to the traveling frame and driven by a first power mechanism to slide back and forth along the traveling frame, a material picking and dispensing mechanism 5 provided on the traveling support 3, specifically, the material picking and dispensing mechanism is located in the center of the traveling support 3, and traveling material support mechanisms 2 are provided on both sides of the material picking and dispensing mechanism, each of the traveling material support mechanisms is connected to a second power mechanism and is driven by the second power mechanism to slide left and right along the traveling support 3, the traveling support 3 is driven by the first power mechanism, wherein both the first power mechanism and the second power mechanism are located on the traveling support 3, and several fixed material support mechanisms 6 are provided at the bottom of the traveling support 3. A height difference is provided between the moving material support mechanism and the fixed material support mechanism, allowing the moving material support mechanism to slide under the fixed material support mechanism. Both the moving and fixed material support mechanisms can switch between rotating extension and rotating retraction working states by rotating. The moving frame has a hopper 4 and a guide frame 7 arranged sequentially along the material conveying direction. The guide surface at the top of the guide frame is set at an angle from high to low, so that when the material falls onto the guide frame, it will automatically roll down the guide frame to the next station under its own weight. The height of the hopper and the guide frame is lower than the height of the moving frame, which facilitates the unobstructed descent and upward feeding of the material picking and distributing mechanism. The material in this application is steel bars, and the equipment is controlled automatically by a controller.

[0038] The material handling and distribution mechanism includes a main frame 5-5 and a lifting mechanism 5-4 fixed on the traveling frame. The main frame is driven to move vertically up and down by the lifting mechanism. Simultaneously, a suction mechanism 5-2 and a sensor trigger plate 5-13 are located at the bottom of the main frame. A proximity sensor 14 is located at the front end of the main frame facing the conveying direction. Both sides of the main frame are equipped with hooking and traveling mechanisms 5-3, each connected to a hooking mechanism 5-1. The hooking mechanism has a slider 5-6, which is slidably connected to a slide rail 5-7 on the side of the main frame. Each hooking mechanism is driven by the hooking and traveling mechanism to slide back and forth along the material conveying direction. The suction mechanism descends continuously with the main frame. When the induction trigger plate touches the material and is lifted by the material, the proximity sensor detects the material, indicating that the material picking position has been reached. The suction mechanism will stop descending and begin to pick up the material. If the suction mechanism continues to descend and reaches its limit position without the induction trigger plate detecting the material, it means that the hopper is empty and the system will automatically alarm. The induction trigger plate is movably connected to the main frame through a guide column that runs through the main frame. It descends by its own weight and will be lower than the suction mechanism. When it comes into contact with the steel bar, the steel bar will push the induction trigger plate upward. If the material falls off during the upward movement of the suction mechanism, the induction trigger plate will also descend, and the controller will also indicate that the material has fallen off.

[0039] The material hooking mechanism includes a first lifting cylinder 5-8 and a second lifting cylinder 5-9. The second lifting cylinder is slidably connected to the slide rail on the side of the main frame via a slider. At the same time, the second lifting cylinder is connected to the synchronous belt 5-10 of the material hooking walking mechanism. The piston rod at the top of the first lifting cylinder and the second lifting cylinder are connected. The piston rod at the bottom of the first lifting cylinder is connected to a hook 5-11. A sensing plate 5-12 is provided at the front end of the hook. When the piston rod of the second lifting cylinder extends and the piston rod of the first lifting cylinder retracts, the hook of the material hooking mechanism reaches the top origin position. When the piston rod of the second lifting cylinder retracts and the piston rod of the first lifting cylinder extends, the hook of the material hooking mechanism descends to the material hooking position. The material hooking walking mechanism drives the material hooking mechanism to move forward. When the sensing plate senses the material, the forward movement stops. The piston rod of the first lifting cylinder remains extended, and the piston rod of the second lifting cylinder extends, causing the hook of the material hooking mechanism to reach the material hooking position, thereby hooking the material.

[0040] The traveling frame has I-shaped slide rails 8 on both sides of its bottom. Each I-shaped slide rail includes an upper wing plate, a connecting plate, and a lower wing plate arranged from top to bottom. The traveling material support mechanism includes guide wheel mounting brackets 2-10, which are connected to the second power mechanism. Both ends of the guide wheel mounting brackets are equipped with guide wheel devices that slide against the outer side of the corresponding I-shaped slide rail. Each guide wheel device includes a vertical guide wheel and a horizontal guide wheel 2-16. The vertical guide wheel includes an upper vertical guide wheel 2-14 and a lower vertical guide wheel 2-13 arranged from top to bottom. The upper and lower vertical guide wheels are respectively attached to the top and bottom of the lower wing plate of the track, and the horizontal guide wheel is attached to the connecting plate of the track. The vertical and horizontal guide wheels enable the traveling material support mechanism to be limited to the left and right and up and down on the I-shaped guide rails, facilitating the sliding of the traveling material support mechanism on the I-shaped guide rails under the drive of the second power mechanism. A rotating machine is connected to the bottom of the guide wheel mounting bracket. The rotating mechanism mounting bracket 2-9 has a third cylinder 2-8 connected to its bottom. The rotating mechanism mounting bracket has a rotating roller bracket 2-3 and a first rotating connecting plate 2-4 at its top and bottom facing the front end of the hopper, respectively. The piston rod end of the third cylinder is rotatably connected to one end of the first rotating connecting plate via a first rotating shaft. The other end of the first rotating connecting plate is rotatably connected to the end of the rotating roller bracket near the first rotating connecting plate via a second rotating shaft. A material support roller 2-2 is provided on the rotating roller bracket along the material conveying direction. When the piston rod of the third cylinder extends, it drives the material support roller to rotate out and support the material through the linkage of the first rotating connecting plate. When the piston rod of the third cylinder retracts, it drives the material support roller to rotate 90 degrees through the linkage of the first rotating connecting plate to avoid the material.

[0041] The fixed material support mechanism includes a mounting plate 6-1 connected to the bottom of the traveling frame. A fourth cylinder 6-2 is connected to the bottom of the mounting plate. A fisheye connector 6-3 is provided at the piston rod end of the fourth cylinder. A second rotating connecting plate 6-4 is provided between the mounting plate and the fourth cylinder. A rotating material support plate 6-5 is fixedly connected to the front end of the second rotating connecting plate. The fisheye connector is connected to one end of the second rotating connecting plate near the rotating material support plate via a rotating shaft 6-6. The other end of the second rotating connecting plate is connected to the mounting plate shaft. A limiting pin 6-7 is provided on one side of the mounting plate for limiting the rotation position of the rotating material support plate. When the piston rod of the fourth cylinder extends, it drives the rotating material support plate to rotate out and support the material through the linkage of the second rotating connecting plate. The piston rod of the four cylinders retracts, and through the linkage of the second rotating connecting plate, the rotating material support plate rotates 90 degrees to retract and avoid the material. Each fixed material support mechanism has a corresponding sensor 10 set on the traveling frame to sense the passage of the traveling material support mechanism. The front and rear ends of the fourth cylinder are equipped with magnetic switches. The front magnetic switch is used to sense the extension of the fourth cylinder into place, and the rear magnetic switch is used to sense the retraction of the fourth cylinder. When the traveling material support mechanism passes the position of a fixed material support mechanism, the corresponding sensor senses that the traveling material support mechanism has reached the position, and the fixed material support mechanism rotates to the working position to support the material. When the front magnetic switch of the fourth cylinder senses that the cylinder has extended into place, the traveling material support mechanism continues to travel to both sides.

[0042] Based on the automatic rebar feeding and dispensing equipment, its working method is also provided, including the following steps.

[0043] S1, the equipment receives the material loading signal, the traveling frame moves to the designated position in the hopper, the material picking and distributing mechanism descends until the induction trigger plate senses the material, indicating that the material picking position has been reached, the suction mechanism stops descending. If the suction mechanism continues to descend and the induction trigger plate does not sense the material after descending to the limit position, it means that the hopper is empty, the system will automatically alarm and notify the manual replenishment.

[0044] S2, after the material handling and distribution mechanism descends to the material handling position, the material suction mechanism sucks up the material;

[0045] S3, after the material is sucked up, the material picking and distributing mechanism rises to the designated position, the hooking mechanism descends, and the hooking and traveling mechanism moves forward. During the rising process of the material picking and distributing mechanism, the induction trigger plate will always sense that the material picking mechanism has picked up the material. If the material falls off during the rising process, the induction trigger plate will descend and lose its sensing function, the system will alarm, and it will prompt that the material has fallen off and the material will be picked up again.

[0046] S4, after the sensor detects the material, the hooking and walking mechanism stops moving forward, the hooking mechanism rises to hook the material, the suction mechanism stops sucking the material, the excess material is removed, the suction mechanism sucks up the material hooked by the hooking mechanism again, and the material picking and distributing mechanism continues to rise to the designated position.

[0047] S5, the walking material support mechanism at both ends of the material picking and distributing mechanism rotates and extends to the working state, and the walking material support mechanism moves from the middle to both sides to lift the material.

[0048] S6, after the walking material support mechanism passes through the position of the fixed material support mechanism, the corresponding sensor detects that the walking material support mechanism has arrived in place, and the fixed material support mechanism rotates to the working position to support the material.

[0049] S7, after all the fixed material support mechanisms rotate and extend to the working position to support the material, the traveling material support mechanisms at both ends reach the designated material support position, and the traveling frame moves to the material dropping position;

[0050] S8, the hooking mechanism descends first, then the hooking walking mechanism returns to the origin, all fixed material support mechanisms rotate and retract to the waiting position, the suction mechanism stops suctioning, the two-end walking material support mechanisms continue to walk to both ends, the material falls onto the guide frame and rolls down the guide frame to the next station;

[0051] S9, all mechanisms return to the origin, and the entire workflow is repeated for the next material picking, sorting and feeding.

[0052] During implementation, the equipment receives a material loading signal, the traveling frame moves to the designated position in the hopper, and the material handling and distribution mechanism descends until the induction trigger plate senses the material and is lifted by it. The proximity sensor then senses the material, indicating that the material handling position has been reached, and the suction mechanism stops descending. If the suction mechanism continues to descend to its limit position without the induction trigger plate sensing the material, it means the hopper is empty, and the system will automatically alarm to notify manual replenishment. Once the material handling and distribution mechanism reaches the material handling position, the suction mechanism picks up the material. After picking up the material, the material handling and distribution mechanism rises to the designated position, the hooking mechanism descends, and the hooking traveling mechanism moves forward. During the ascent, the induction trigger plate continuously senses that the suction mechanism has picked up the material. If the material falls off during the ascent, the induction trigger plate descends and loses its sensing function, the system alarms, indicating that the material has fallen off, and the material handling needs to be restarted. Once the induction plate senses the material, the hooking traveling mechanism stops moving forward, the hooking mechanism rises to hook the material, the suction mechanism stops picking up the material, and excess material is removed. After rejection, the suction mechanism picks up the material hooked by the hooking mechanism again. The material picking and distributing mechanism continues to rise to the designated position. At this time, the walking material-supporting mechanisms at both ends of the material picking and distributing mechanism rotate and extend to the working state. The walking material-supporting mechanisms move from the middle to both sides to lift up the material. After each walking material-supporting mechanism passes the position of a fixed material-supporting mechanism, the corresponding sensor senses that the walking material-supporting mechanism has arrived at the position. The fixed material-supporting mechanism rotates to the working position to support the material. After all the fixed material-supporting mechanisms rotate and extend to the working position to support the material, the walking material-supporting mechanisms at both ends reach the designated material-supporting position. The walking frame moves to the material-dropping position. The hooking mechanism descends first and then the hooking walking mechanism returns to the origin. All the fixed material-supporting mechanisms rotate and retract to the waiting position. The suction mechanism stops suctioning. The walking material-supporting mechanisms at both ends continue to move to both ends. The material falls to the guide frame and rolls down the guide frame to the next work station. Finally, all mechanisms return to the origin and repeat the entire process to pick up, distribute and feed the material for the next time.

S5, the walking material support mechanism at both ends of the material picking and distributing mechanism rotates and extends to the working state, and the walking material support mechanism moves from the middle to both sides to lift the material. S6, after the walking material support mechanism passes through the position of the fixed material support mechanism, the corresponding sensor detects that the walking material support mechanism has arrived in place, and the fixed material support mechanism rotates to the working position to support the material. S7, after all the fixed material support mechanisms rotate and extend to the working position to support the material, the traveling material support mechanisms at both ends reach the designated material support position, and the traveling frame moves to the material dropping position; S8, the hooking mechanism descends first, then the hooking walking mechanism returns to the origin, all fixed material support mechanisms rotate and retract to the waiting position, the suction mechanism stops suctioning, the two-end walking material support mechanisms continue to walk to both ends, the material falls onto the guide frame and rolls down the guide frame to the next station; S9, all mechanisms return to the origin, and the entire workflow is repeated for the next material picking, sorting and feeding.
