Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, in particular to an iron core feeding and winding mechanism. Background Art

[0002] The sheet steel feeding structure in the existing iron core production often gets stuck or drawn into the equipment gap due to the weight of the tail end of the material sagging, causing material damage or shutdown failure. Traditional solutions mostly use rigid blocking structures or complex sensors to monitor the tail end position, but rigid blocking can easily cause material bending, and the sensor system is expensive and easily interfered with; in addition, the transition structure design between the buffer trough and the conveying device needs to be improved, and the buffer trough can easily cause the tail end to be retained or friction to aggravate surface scratches. Some equipment attempts to lift the tail end mechanically, but the action is delayed or increases the possibility of additional wear and jamming, and even aggravates material deformation. The above problems restrict the realization of high-speed continuous production, and there is an urgent need for a solution that can take into account flexible transition, lossless conveying and material protection.

[0018] See also Figures 1 to 13 As shown, an iron core feeding and winding mechanism of an embodiment of the present application includes a conveying device 10 and a winding device 30, the conveying device 10 is used to convey a sheet steel material 50, the winding device 30 is arranged at the output side of the conveying device 10, the conveying device 10 and the winding device 30 are also provided with a buffer groove 40, the iron core feeding and winding mechanism also includes a middle material receiving bridge 20, the middle material receiving bridge 20 is arranged between the conveying device 10 and the buffer groove 40, and the middle material receiving bridge 20 has an arc-shaped end surface on one side close to the buffer groove 40; The middle material receiving bridge 20 is provided with: an air storage and steering structure 21, a flexible connection structure 23 and an upward throwing structure 25. The upward throwing structure 25 is rotatably arranged on a side of the middle material receiving bridge 20 away from the winding device 30, and the upward throwing structure 25 is in contact with the steel 50; the air storage and steering structure 21 is connected to the upward throwing structure 25, driving the upward throwing structure 25 to form a horizontal posture and an inclined posture. The horizontal posture is used for continuous transportation of the steel 50, and the inclined posture is used for transportation of the tail end of the steel 50, so as to form an upward throwing action in which the tail end of the steel 50 can be away from the middle material receiving bridge 20 and the buffer tank 40; the flexible connection structure 23 is arranged on the end of the air storage and steering structure 21, and is used to sense the position information of the material at the tail end of the steel 50 and flexibly receive the material at the tail end of the steel 50.

[0019] In the iron core feeding and winding mechanism provided by the present application, the middle material receiving bridge 20 is connected with the buffer groove 40 through the arc-shaped end face, forming a transition section of the conveying path of the steel 50; the upper throwing structure 25 serves as the bearing and guiding surface of the steel 50 in a horizontal posture, and cooperates with the conveying device 10 to maintain the continuous conveying of the steel 50. When the tail end of the steel 50 approaches, the air storage and steering structure 21 drives the upper throwing structure 25 to tilt around its rotating end, and uses the tilt angle to change the motion trajectory of the tail end of the steel 50, so that it detaches from the surface of the middle material receiving bridge 20 and is thrown up to a position away from the buffer groove 40, avoiding the tail end from sagging, getting stuck and being damaged; the flexible connection structure 23 senses the position of the tail end of the steel 50 through mechanical contact, and buffers the impact force of the tail end through its own deformation when the upper throwing structure 25 tilts, thereby ensuring the flexible transition of the tail end of the steel 50 from the conveying device 10 to the upper throwing structure 25. The specific process is as follows: during normal transportation, the upper throwing structure 25 remains horizontal, and the steel 50 passes through the middle material receiving bridge 20 through the conveying device 10 and enters the buffer tank 40; when the tail end of the steel 50 reaches the end of the upper throwing structure 25, the gas storage and steering structure 21 triggers the tilting action, and the upper throwing structure 25 is lifted to form a projectile inclined plane. The tail end is thrown away from the buffer tank 40 area under the action of its own weight inertia and the inclined plane. At the same time, the flexible connection structure 23 fits the tail end through elastic deformation to reduce the bending stress of the material. This structure solves the problem of the tail end of the sheet steel 50 being stuck and damaged due to the drooping of its own weight through dynamic posture switching. The curved end face optimizes the path of the steel 50. The pneumatic steering and flexible connection work together to reduce the risk of material damage and improve the continuity and stability of feeding.

[0020] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 11 and Figure 13 As shown, in some examples, further, the gas storage and steering structure 21 includes: a telescopic rod 211, two gas storage containers 212, an air intake filter assembly 213 and a conveying pipe 214, one end of the telescopic rod 211 can be rotatably connected to the upper throwing structure 25; the other end of the telescopic rod 211 can be rotatably connected to the bridge body of the middle material receiving bridge 20; at least one gas storage container 212 is parallel to the telescopic rod 211, and the gas storage container 212 has a reciprocating piston assembly, and each piston assembly is connected to the telescopic end of the telescopic rod 211; the air intake filter assembly 213 is connected to the gas storage container 212, and is used to filter the air entering the gas storage container 212; one end of the conveying pipe 214 is connected to the gas storage container 212, and the other end is connected to the upper throwing structure 25.

[0021] In the air storage and steering structure 21, the telescopic rod 211 can be set as an electric push rod or a hydraulic rod. The telescopic rod 211 realizes the switching between the horizontal and inclined postures of the upward throwing structure 25 through rotational connections at both ends. The telescopic rod 211 has a telescopic end, and the telescopic end is mechanically connected to the piston assembly through a common connecting seat (please refer to Figure 13 as shown). Its telescopic movement directly drives the piston assembly in the air storage container 212 to reciprocate: when the telescopic rod 211 contracts, the piston compresses the air in the air storage container 212 to form a high-pressure air flow, which is injected into the upward throwing structure 25 through the conveying pipeline 214; when the telescopic rod 211 extends, the piston pulls back to inhale external air to supplement the air pressure in the container and maintain pneumatic continuity. The two air storage containers 212 are designed in parallel to enhance the air pressure stability and ensure sufficient air flow output during the inclined movement of the upward throwing structure 25; the conveying pipeline 214 conveys the compressed air to the air flow ejection unit (such as the exhaust hole group) of the upward throwing structure 25, and uses the air flow thrust to assist the tail end of the steel 50 to break away from the guiding surface and complete the upward throwing, and form an air flow diaphragm between the steel 50 and the middle material receiving bridge 20 to prevent the problem of conveying wear. Therefore, the air storage and steering structure 21 realizes dual drive through mechanical telescoping and pneumatic linkage. The physical displacement of the telescopic rod 211 directly controls the angle of the upward throwing structure 25, and the tail end is thrown out of the buffer groove 40 area under the action of its own gravity inertia and the inclined plane. At the same time, the compressed air provides an additional ejection force, and the two cooperate to improve the tail end throwing effect; finally, the rapid and controllable throwing action of the tail end of the steel 50 is realized, and the risk of material deformation caused by mechanical impact is reduced.

[0022] As Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 12 as shown, in some examples, furthermore, the flexible connection structure 23 includes a flexible metal plate. One end of the flexible metal plate is fixedly connected to the end of the upward throwing structure 25, and the other end of the flexible metal plate can be horizontally movably clamped under the conveying device 10; when the upward throwing structure 25 is in a horizontal state, the flexible metal plate, the steel 50 and the side wall of the conveying device 10 enclose a non-contact area 231. A rotary encoder assembly 232 is arranged on the flexible metal plate. The non-contact area 231 is used to accommodate the rotary encoder assembly 232. The non-contact area 231 provides an avoidance space for the rotary encoder assembly 232 in the horizontal state, and makes the rotary encoder assembly 232 contact the steel during the inclined state with the displacement of the flexible metal plate.

[0023] When the upward throwing structure 25 is in an inclined state, the flexible metal plate connected to one side of the upward throwing structure 25 inclines downward, and the rotary encoder assembly 232 can contact the steel material 50. The rotary encoder assembly 232 is used to obtain the timing when the steel material 50 enters the surface of the upward throwing structure 25 in the inclined state and the timing when the steel material 50 detaches from the flexible metal plate.

[0024] In the flexible connection structure 23, the flexible metal plate forms a dynamic deformation structure through the setting of being fixedly connected to the upward throwing structure 25 at one end and horizontally sliding and clamping the conveying device 10 at the other end: when the upward throwing structure 25 is in a horizontal state, the flexible metal plate, the side wall of the conveying device 10 and the steel material 50 jointly enclose a non-contact area 231, providing an avoidance space for the rotary encoder assembly 232 to avoid friction loss between the steel material 50 and the encoder during normal conveying; when the upward throwing structure 25 inclines, the flexible metal plate inclines downward with the connection end, and the rotary encoder assembly 232 moves out of the non-contact area 231 and contacts the surface of the tail end of the steel material 50. Through the pulse signal generated by the encoder roller moving with the steel material 50, the position where the tail end of the steel material 50 enters the inclined section and the detachment moment are captured in real time, and the signal is fed back to the control system to accurately control the start and stop timing of the upward throwing action.

[0025] The specific process is as follows: when the tail end of the steel material 50 approaches, the flexible metal plate inclines downward with the upward throwing structure 25. When the tail end completely detaches from the conveying device 10, the rotary encoder assembly 232 contacts the surface of the steel material 50 and starts to record the displacement; when the encoder detects that the steel material 50 has displaced through the rotary encoder assembly 232, the pneumatic injection of the upward throwing structure 25 is triggered.

[0026] As Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 12 shown, in some examples, further, the upward throwing structure 25 includes: a guide plate 251, a first exhaust hole group 252, a second exhaust hole group 253 and a control valve 254. The guide plate 251 is rotatably arranged in the middle material receiving bridge 20, and one end of the guide plate 251 close to the winding device 30 is the rotating end; the first exhaust hole group 252 is arranged in an array along the direction perpendicular to the conveying direction of the steel material 50 on the surface of the guide plate 251 and corresponds to the position of the rotating end of the guide plate 251; the second exhaust hole group 253 is arranged on the surface of the guide plate 251 and is located on the side far from the first exhaust hole group 252; the control valve 254 is arranged on the guide plate 251 and is connected to the air pipeline of the second exhaust hole group 253.

[0027] In the upward throwing structure 25, the guide plate 251 is hinged to the middle material receiving bridge 20 through a rotating end, forming a steel material bearing surface with an angle that can be dynamically adjusted. During normal conveying, the guide plate 251 remains horizontal, and the steel material 50 slides smoothly along its surface towards the buffer tank 40. The first exhaust hole group 252 is densely distributed along the rotating end, releasing a small flow of air at the initial stage of the inclination of the guide plate 251, reducing the frictional resistance by evenly blowing the surface of the steel material 50, and avoiding jamming at the tail end due to sudden angle changes. The second exhaust hole group 253 is located at the distal end of the guide plate 251, and the air pressure in the connecting pipeline is adjusted through the control valve 254. When the tail end of the steel material 50 needs to be thrown upward, the control valve 254 is opened to release the high-pressure air flow in the gas storage container 212, which sprays out from the second exhaust hole group 253 to form a strong thrust, driving the tail end to accelerate and break away from the guide plate 251 to complete the upward throwing action.

[0028] During the working process, when the guide plate 251 is in a horizontal state, the first exhaust hole group 252 maintains the basic air flow to assist in conveying. After the encoder detects that the steel material 50 has displaced past the rotary encoder assembly 232, the control valve 254 responds to the signal to open the air flow of the second exhaust hole group 253. By utilizing the synergistic effect of the concentrated jet force at the distal end and the inclination angle of the guide plate 251, the tail end is thrown to a preset position. At the same time, the first exhaust hole group 252 continuously outputs auxiliary air flow to ensure the smooth separation of the steel material 50. Through the partitioned exhaust hole group, the gradient control of the air flow intensity and the action range is realized, which not only reduces the energy consumption during continuous conveying but also can concentrate the air flow kinetic energy during the throwing stage, control the movement trajectory of the tail end, and reduce the deformation risk of the material caused by local stress concentration.

[0029] The tilting action forms a throwing inclined plane through the rotation of the guide plate 251, enabling the tail end of the steel material 50 to naturally obtain an upward initial velocity under the action of the component of gravity. The air storage and turning structure 21 drives the piston to compress air through the telescopic rod 211 during the tilting process, forming a high-pressure air source to provide power for the jet. After tilting, the concentrated jet direction of the second exhaust hole group 253 forms an angle with the movement direction of the steel material 50, converting the air flow kinetic energy into a throwing force and improving the throwing efficiency. The first exhaust hole group 252 releases a small flow of air at the initial stage of tilting, reducing the friction between the steel material 50 and the guide plate 251 through the air floating effect, preventing local stress concentration caused by sudden jetting in the horizontal state, and realizing the reliability of the tail end treatment of the material.

[0030] As Figure 12 shown, in some examples, furthermore, the diameter of the air supply pipeline of the first exhaust hole group 252 is smaller than that of the air supply pipeline of the second exhaust hole group 253.

[0031] In the upward structure 25, the diameter of the air supply pipeline of the first exhaust hole group 252 is smaller than that of the second exhaust hole group 253: the small diameter of the first exhaust hole group 252 limits the air flow rate, so that it continuously outputs a stable small air flow during the conveying stage, and forms an evenly distributed air flow diaphragm between the guide plate 251 and the steel 50, thereby reducing the sliding friction between the steel 50 and the surface of the guide plate 251 through the flotation effect, and avoiding the adhesion of debris; the large diameter design of the second exhaust hole group 253 matches the high-pressure air source of the air storage container 212, and instantly releases a large amount of compressed air when the control valve 254 is opened, forming a concentrated strong thrust, quickly overcoming the inertia of the tail end of the steel 50 and driving it to leave the surface of the guide plate 251.

[0032] like Figure 6 and Figure 7 As shown, in some examples, further, a vertical adsorption and fixing structure 22 is also provided on the middle material receiving bridge 20, which is used to electromagnetically adsorb and fix a section of the steel plate that hangs down to the buffer groove 40; the vertical adsorption and fixing structure 22 includes; a rotating chamber 221, a rotating seat 222, a rotating shaft 223, an electromagnet 224 and a contact power supply seat 225, the rotating chamber 221 is opened on the arc-shaped end face of the middle material receiving bridge 20 close to the buffer groove 40; the rotating seat 222 is rotatably arranged in the rotating chamber 221, and the outer end face of the rotating seat 222 matches the shape of the arc-shaped end face of the middle material receiving bridge 20 close to the buffer groove 40; the rotating shaft 223 is rotatably arranged in the rotating chamber 221 and passes through the upper half of the rotating seat 222; the electromagnet 224 is fixedly arranged in the inner wall of the rotating seat 222 close to the arc-shaped end face; the contact power supply seat 225 is fixedly installed in the inner cavity of the middle material receiving bridge 20.

[0033] The working process of the vertical adsorption and fixation structure 22 is as follows: During normal transportation, the electromagnet 224 is de-energized, and the rotating seat 222 is housed in the rotating cavity 221. When the tail end of the steel material 50 is detected by the blanking monitoring sensor 11, the gas storage and steering structure 21 drives the upward throwing structure 25 to tilt. The tail end slides onto the surface of the inclined guide plate 251 and contacts the rotary encoder assembly 232. The encoder trigger signal energizes the contact power supply seat 225, activating the electromagnet 224 to adsorb and fix the drooping section of the steel material 50 on the middle material receiving bridge 20. At this time, the winding device 30 continuously winds the remaining part in the buffer tank 40. As the remaining amount decreases, the steel material 50 gradually tightens and pulls the rotating seat 222 to rotate outward around the rotating shaft 223. When the remaining amount is completely wound and the steel material 50 has no droop, the rotating seat 222 rotates to a power-off position away from the contact power supply seat 225, and the electromagnet 224 demagnetizes to release the steel material 50. Immediately afterwards, the upward throwing structure 25 ejects high-pressure air through the second exhaust hole group 253 to throw the tail end away from the guide plate 251, so that it avoids the falling path of the buffer tank 40. This process realizes seamless switching from fixation to throwing of the tail end through the precise cooperation of sensing trigger, electromagnetic adsorption and mechanical linkage, preventing the drooping section from interfering with winding and ensuring a clean separation of the throwing action, ultimately solving the problems of tail end jamming and material damage in the traditional structure.

[0034] As Figure 6 and Figure 7 shown, in some examples, furthermore, the contact power supply seat 225 includes a contact power supply end, and another contact power receiving end is arranged in the rotating seat 222. When the rotating seat 222 is in the default state, the contact power supply end is in communication with the contact power receiving end; when the lower end of the rotating seat 222 rotates outward, the contact power supply end is separated from the contact power receiving end.

[0035] In this example, the contact power supply seat 225 realizes power transmission through the physical contact between the contact power supply end and the contact power receiving end in the rotating seat 222: In the default state, the rotating seat 222 is completely housed in the rotating cavity 221, and the two contact points are closely attached to continuously supply power to the electromagnet 224 to maintain adsorption. When the remaining amount of the steel material 50 is wound up and the drooping section is tightened, the pulling force of the steel material 50 drives the rotating seat 222 to rotate outward around the rotating shaft 223, and its lower end gradually separates from the contact power supply end, resulting in the separation of the contact power supply end and the power receiving end of the rotating seat 222 due to relative displacement, and the electromagnet 224 immediately cannot adsorb the steel material 50 to be thrown upward. In this example, the power supply end and the power receiving end adopt a sliding contact or spring pin structure to ensure the contact stability of the rotating seat 222 within the rotation range (default position to the outer rotation limit); the separation action is realized through pure mechanical linkage without additional sensor control, and the power-off response speed is strictly synchronized with the displacement of the rotating seat 222.

[0036] The specific functions include: 1) During the default adsorption stage, the reliable fixation of the steel material 50 is ensured by stable power supply; 2) When externally rotating and separating, the power supply is forcibly cut off to eliminate the interference of residual magnetic force on the ejection action. Through the conduction and separation of physical contact, the start and stop of electromagnetic adsorption are directly bound to the position of the rotating seat 222, simplifying the control logic and ensuring the precise action timing, ultimately realizing the seamless connection between the release and upward ejection actions of the steel material 50.

[0037] As Figure 1 and Figure 2 shown, in some examples, furthermore, a material breakage monitoring sensor 11 is also provided on the conveying device 10, and a control box 24 is also provided on the middle material receiving bridge 20. The signal output ends of the material breakage monitoring sensor 11 and the rotary encoder assembly 232 are connected to the signal input end of the control box 24, and the control end is connected to the driving units of the contact power supply seat 225 and the telescopic rod 211 through electrical signals.

[0038] The material breakage monitoring sensor 11 on the conveying device 10 continuously detects the remaining amount of the steel material 50, and sends a trigger signal to the control box 24 when the tail end of the steel material 50 approaches; sends a contraction signal to the driving unit of the telescopic rod 211 to drive the upward ejection structure 25 to tilt. After the upward ejection structure 25 tilts, the rotary encoder assembly 232 continuously monitors the displacement of the tail end of the steel material 50 and generates a pulse signal to feedback to the control box 24. The control box 24 outputs an energization instruction to the contact power supply seat 225 to activate the electromagnetic iron 224 for adsorption; when the winding device 30 winds the remaining material until the steel material 50 is tightened, the rotary encoder detects the displacement stagnation and can sense that the current winding structure is winding the remaining part. After the winding structure finishes winding the remaining part, the electromagnetic iron 224 loses the adsorption ability for the steel material 50. The rotary encoder detects the movement of the steel material 50 again, and the signal is transmitted to the control box 24 again. At this time, the control box 24 forces the control valve 254 to open instantly to perform the upward ejection action. In this example, the mechanical action and the electrical response are deeply bound, which not only avoids the delay of manual intervention but also improves the system's adaptability, enabling the entire process of tail end processing to be completed automatically and with high precision.

[0039] In some examples, furthermore, the signal output end of the control box 24 is connected to the motor controller of the winding motor in the conveying device 10 (not shown in the figure) for changing the rotation speed of the winding motor.

[0040] The control box 24 is connected to the motor controller of the winding motor through the signal output end to form a dynamic speed regulation closed loop: during normal conveying, the control box 24 sends a constant speed instruction to the motor controller to ensure that the steel material 50 enters the buffer tank 40 at a uniform speed; when the material is ejected, the control box 24 immediately increases the motor speed to ensure that the upward ejection height and power of the material under the action of inertia are sufficient; improving the overall operation efficiency and material utilization rate.

[0041] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
