Description

Technical Field

[0001] This invention relates to the field of transformer core production equipment, and more specifically, to an automated stacking equipment for a silicon steel coil and strip shearing machine. Background Technology

[0002] In the manufacturing of power equipment such as transformer cores, silicon steel coils need to be cut into sheets of specific sizes by a shearing machine, and then stacked. To improve production efficiency, the production line often needs to sort the silicon steel sheets onto upper and lower conveyor belts, each corresponding to a stacking station with different models or flow directions. In this process, the diversion device located between the shearing machine and the conveyor belt is particularly crucial, as its function is to quickly and accurately guide the cut silicon steel sheets to a predetermined path.

[0003] Traditional diversion devices typically consist of fixed upper and lower guide plates and a swingable diversion valve plate. By driving the diversion valve plate to flip up or down, it is brought close to the lower or upper guide plate respectively, thus forming channels for guiding different conveyor belts. However, in such devices, the fit clearance between the diversion valve plate and the upper and lower guide plates is usually a fixed value set during mechanical installation. This fixed clearance design reveals significant limitations in actual operation: First, it cannot adapt to silicon steel sheets of different thicknesses, hardnesses, or surface conditions. For thicker sheets, insufficient clearance can easily cause jamming, while for thinner sheets, excessive clearance may lead to unstable diversion, sheet leakage, or mis-diversion. Second, after long-term high-speed operation, the hinged parts inevitably wear down, and the mechanical structure may also undergo slight deformation due to temperature rise or stress. These factors can cause changes in the initially set fixed clearance, resulting in diversion failures. Furthermore, whenever the specifications of the production sheets are changed, it is often necessary to stop the machine and manually adjust the mechanical parts to readjust the clearance, severely restricting the continuity and flexibility of the production line.

[0004] Therefore, how to achieve online, dynamic and precise control of the gap between the diversion channels to adaptively compensate for mechanical wear and thermal deformation and adapt to different product specifications, thereby ensuring the continuous stability and precision of high-speed diversion and realizing subsequent precise stacking, has become a technical problem that urgently needs to be solved in this field.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Silicon steel coils need to be stacked and collected using stacking equipment after being cut by a cross-cutting machine. Since the cross-cutting machine has a fast cutting speed and the same production line needs to cut silicon steel coils into two types, two layers of conveyor belts are usually used for stacking and collecting.

[0040] See Figure 1The shearing machine has two conveyor belts, one upper and one lower, at the rear. Each conveyor belt has a material plate at its rear end, where the cut silicon steel sheets are neatly arranged. Both material plates have identical unloading structures, such as the transport components and ejector structures provided in announcement number CN116986336B. The transport components are installed at the rear ends of both conveyor belts to receive the silicon steel sheets, and the ejector structures on the transport components knock the sheets onto the material plates, ensuring neat stacking of the cut sheets. To better transport the silicon steel sheets via the two conveyor belts, a diversion structure needs to be installed at the front ends of both conveyor belts.

[0041] Example 1, see Figure 2 An automated stacking device for a silicon steel coil and strip shearing machine is provided, including a diversion device 1, an upper conveyor belt 2 and a lower conveyor belt 3. The upper conveyor belt 2 and the lower conveyor belt 3 are arranged in a transverse V-shape. One end of the upper conveyor belt 2 and the lower conveyor belt 3 are connected to the diversion device 1. The diversion device 1 includes a base 101, a diversion valve plate 102, an upper baffle 103 and a lower baffle 104. The base 101 is the main mounting body. The upper baffle 103 and the lower baffle 104 are both installed inside the base 101. The diversion valve plate 102 is rotatably connected to the inner wall of the base 101, and a first adjustment mechanism 105 for driving the diversion valve plate 102 to flip is installed on the outer wall of the base 101.

[0042] See Figure 3 The first adjusting mechanism 105 specifically includes a first telescopic rod 1051, a pull arm 1052, an angle sensor 1053, a valve plate rotating rod 1054, and an upper guide seat 1055. The upper guide seat 1055 is fixed to the base 101. Both ends of the valve plate rotating rod 1054 are rotatably connected to the upper guide seat 1055 via bearings. The diverter valve plate 102 is fixed to the valve plate rotating rod 1054. The cylinder end of the first telescopic rod 1051 is hinged to the base of the base 101, and its piston rod end is drivenly connected to one end of the valve plate rotating rod 1054 via the pull arm 1052. When the first telescopic rod 1051 (which can be an electric push rod or a cylinder) extends or retracts, it drives the valve plate rotating rod 1054 to rotate via the pull arm 1052, thereby driving the diverter valve plate 102 to rotate around its axis. The angle sensors 1053 installed at both ends of the valve plate rotating rod 1054 are used to detect the rotation angle of the diverter valve plate 102 in real time.

[0043] See Figure 4 and Figure 5When the diversion valve plate 102 is driven to flip downwards, an "upper channel" is formed between its plate and the upper baffle 103 above it. The outlet of this channel is connected to the inlet of the upper conveyor belt 2, through which the silicon steel sheets are guided to the upper conveyor belt 2. When the diversion valve plate 102 flips upwards, a "lower channel" is formed between its plate and the lower baffle 104 below it. The outlet of this channel is connected to the inlet of the lower conveyor belt 3, through which the silicon steel sheets are guided to the lower conveyor belt 3. By controlling the extension and retraction of the first telescopic rod 1051, the diversion valve plate 102 can be switched between the two positions, thus completing the dynamic diversion of the silicon steel sheets.

[0044] During the diversion process, the opening size of the upper and lower channels affects the conveying of silicon steel sheets. To ensure the diversion accuracy, this embodiment sets up a closed-loop control system. The closed-loop control system includes a control module and a detection module installed on the side wall of the base 101, which is used to monitor the opening size of the upper and lower channels in real time to ensure that the opening size of the upper and lower channels is within a reasonable range. The detection module adopts a CCD camera.

[0045] Furthermore, the closed-loop control system also includes an angle compensation module. When switching to the upper channel, if the vertical gap between the diversion valve plate 102 and the lower baffle 104 increases, the diversion valve plate 102 needs to be flipped downwards for angle compensation to eliminate the vertical gap between the diversion valve plate 102 and the lower baffle 104 and avoid the silicon steel sheet being missed or misdivided. Similarly, when switching to the lower channel, if the vertical gap between the diversion valve plate 102 and the upper baffle 103 increases, the diversion valve plate 102 needs to be flipped upwards for angle compensation to eliminate the vertical gap between the diversion valve plate 102 and the upper baffle 103.

[0046] It should be noted that the opening size of the upper and lower channels must meet the preset angle to avoid jamming or misdivision due to insufficient opening. The valve plate rotating rod 1054 is used to ensure the flip angle of the diversion valve plate 102. The angle compensation module needs to be activated after the flip angle of the diversion valve plate 102 reaches the preset angle.

[0047] The working process of this embodiment is as follows: When the closed-loop control system switches to the upper channel state, if the detection module detects that the vertical gap between the diversion valve plate 102 and the lower baffle 104 has increased, indicating a risk of leakage, the angle compensation module instructs the first adjustment mechanism 105 to drive the diversion valve plate 102 to slightly rotate downwards to compensate for the vertical gap. Conversely, when switching to the lower channel state, if the vertical gap between the diversion valve plate 102 and the upper baffle 103 is detected to have increased, the diversion valve plate 102 is instructed to slightly rotate upwards to compensate for the vertical gap. This compensation mechanism is activated after the diversion valve plate 102 has rotated to the preset main angle, and is used for fine-tuning compensation to ensure the channel's sealing performance, while avoiding jamming due to excessively small opening.

[0048] Example 2: The angle compensation module in Example 1 can only adjust the diversion valve plate in one direction. When the equipment is worn or deformed due to long-term operation, or when there are errors in the initial installation, it may not be able to completely eliminate all gaps.

[0049] To further improve the elimination of the above errors, please refer to Figure 6 , Figure 7 and Figure 8 In this embodiment, a second adjustment mechanism 106 and a third adjustment mechanism 107 are added to the diversion device 1 in embodiment 1, which are used to independently adjust the position and attitude of the upper baffle 103 and the lower baffle 104, respectively.

[0050] See Figure 6 , Figure 9 The second adjusting mechanism 106 includes an upper fixed seat 1061, an upper lead screw module 1062, and an upper sliding plate 1063. The upper fixed seat 1061 is installed at the top of the base 101. The stationary part of the upper lead screw module 1062 is installed at the bottom of the upper fixed seat 1061. The moving part of the upper lead screw module 1062 is fixedly connected to the top of the upper sliding plate 1063. One end of the upper baffle 103 is hinged to one end of the upper sliding plate 1063. A second telescopic rod 1064 is provided between the upper sliding plate 1063 and the upper baffle 103. One end of the second telescopic rod 1064 is hinged to the upper sliding plate 1063, and the other end... Hinged to the upper baffle 103, the upper baffle 103 can be rotated along the hinge point by the extension and retraction of the second telescopic rod 1064, so as to realize the upward or downward flipping of the upper baffle 103. In order to ensure the stability of the upper baffle 103 during the flipping process, the upper guide plate 1065 is connected to both sides of the upper slide plate 1063. The upper guide plate 1065 is provided with a first arc groove 10651 corresponding to the movement trajectory of the upper baffle 103. A first connecting block 1066 is slidably arranged in the first arc groove 10651. The two ends of the upper surface of the upper baffle 103 are fixedly connected to the first connecting block 1066 by bolts.

[0051] Meanwhile, the upper lead screw module 1062 can drive the upper slide plate 1063 and all its components to move back and forth in the horizontal direction, thereby realizing the adjustment of the overall horizontal position of the upper baffle 103.

[0052] See Figure 6 , Figure 8 , Figure 10The third adjusting mechanism 107 is used to adjust the lower baffle 104. Its structure is symmetrical to that of the second adjusting mechanism 106 and its principle is similar. It mainly includes a lower fixed seat 1071, a lower lead screw module 1072, a lower sliding seat plate 1073, a lower guide plate 1074, a second connecting block 1075, a third telescopic rod 1076, and a lower guide seat 1077. The lower fixed seat 1071 is fixed to the bottom of the base 101. The stationary part of the lower lead screw module 1072 is installed at the top of the lower fixed seat 1071, and the moving part is fixed to the bottom of the lower sliding seat plate 1073. A lower guide seat 1077 is fixed at the inlet of the lower conveyor belt 3. The lower baffle 104 adopts a segmented design, including a core plate 1041 and a sliding sleeve plate 1042. The front end of the core plate 1041 is hinged to the lower guide seat 1077, and its rear end is slidably sleeved within the U-shaped sliding sleeve plate 1042. The two can slide relative to each other to compensate for length changes. The sliding sleeve plate 1042 and the lower sliding seat plate 1073 are connected by a third telescopic rod 1076. The two ends of the third telescopic rod 1076 are hinged to the bottom of the lower sliding seat plate 1073 and the sliding sleeve plate 1042, respectively. Activating the third telescopic rod 1076 can drive the sliding sleeve plate 1042 and the core plate 1041 connected to it to rotate around the hinge point at the front end of the core plate 1041, thereby changing the tilt angle of the lower baffle 104.

[0053] To ensure the structural adaptability of the lower baffle 104 during horizontal displacement, it adopts a segmented design, mainly comprising a core plate 1041 and a sliding sleeve plate 1042. One end of the core plate 1041 is hinged to the lower guide seat 1077, and the other end is slidably inserted into the U-shaped groove of the sliding sleeve plate 1042, forming a retractable sliding fit. Both ends of the sliding sleeve plate 1042 are slidably connected to the second arc groove 10741 provided on the lower guide plate 1074 via second connecting blocks 1075. Thus, when the lower lead screw module 1072 drives the lower slide seat plate 1073 to move horizontally, the sliding sleeve plate 1042 moves accordingly, and the core plate 1041 slides relative to it within the sliding sleeve plate 1042, achieving length compensation, thereby making the lower baffle 104 adjustable in the horizontal direction. Meanwhile, when the third telescopic rod 1076 moves, the core plate 1041 rotates around its hinge point and drives the sliding sleeve plate 1042 to swing synchronously through the sliding connection, thereby realizing the overall tilting angle adjustment of the lower baffle 104. The second arc groove 10741 provides guidance and stable support for the tilting movement of the sliding sleeve plate 1042.

[0054] This embodiment includes the following steps:

[0055] Step 1: The control module activates the first adjustment mechanism 105, the second adjustment mechanism 106 and the third adjustment mechanism 107, so that the diversion valve plate 102, the upper baffle 103 and the lower baffle 104 are reset to their initial positions, and then enters the waiting state.

[0056] Step two: The control module controls the first adjustment mechanism 105 according to the received target flow direction instruction, so that the diversion valve plate 102 is flipped to the corresponding first preset angle, thereby initially establishing a conveying channel connected to the upper conveyor belt 2 or the lower conveyor belt 3.

[0057] Step 3: After the diversion valve plate 102 is positioned, the control module drives the second adjustment mechanism 106 and the third adjustment mechanism 107 to adjust the position and attitude of the upper baffle 103 and the lower baffle 104 respectively.

[0058] The upper slide plate 1063 and the upper baffle 103 connected thereto are driven to move horizontally to a first predetermined position by the upper lead screw module 1062; and the upper baffle 103 is driven to flip around its hinge point to a second predetermined angle by the second telescopic rod 1064.

[0059] Synchronously or sequentially, the lower lead screw module 1072 drives the lower slide plate 1073 to move horizontally, thereby driving the sliding sleeve plate 1042 to move horizontally to the second predetermined position. At this time, the core plate 1041 slides relative to the sliding sleeve plate 1042 for length compensation. The third telescopic rod 1076 drives the core plate 1041 to rotate around its hinge point with the lower guide seat 1077, thereby driving the sliding sleeve plate 1042 to swing synchronously, so that the lower baffle 104 is flipped as a whole to the third preset angle.

[0060] This step creates an optimized conveying channel with both shape and clearance between the upper baffle 103, the lower baffle 104, and the positioned diversion valve plate 102.

[0061] Step four: During the diversion and conveying of silicon steel sheets, the detection module monitors the opening size of the current effective channel in real time and compares it with the preset opening threshold range. If the opening size is determined to be abnormal, the angle compensation module is activated to coordinate and drive the first adjustment mechanism 105, the second adjustment mechanism 106 and the third adjustment mechanism 107 to perform linkage fine adjustment, forming a closed-loop control, so that the channel opening size is restored and stabilized within the preset tolerance range.

[0062] Step 5: After completing the current diversion task, the closed-loop control system maintains the current configuration to prepare to receive the next instruction. If a new instruction for changing the flow direction is received, it returns to Step 2 and re-executes the main channel switching, channel shaping and adjustment, and subsequent dynamic monitoring and compensation processes.

[0063] Through the above-described working method, the second adjusting mechanism 106 and the third adjusting mechanism 107 achieve independent and precise control over the horizontal position and tilting angle of the upper baffle 103 and the lower baffle 104. This method not only performs basic diversion guidance but also actively shapes and dynamically maintains the optimal channel geometry through the coordinated action of multiple mechanisms, thereby effectively improving diversion accuracy and the equipment's adaptability to long-term operating conditions.

[0064] The first preset angle refers to the target angle at which the diversion valve plate 102 needs to be rotated. Its function is to quickly and accurately deflect the diversion valve plate to its theoretical position, initially establishing the main guide for the conveying channel. The first and second predetermined positions refer to the target positions in the horizontal direction that the upper baffle 103 and the lower baffle 104 (via their sliding sleeve 1042) need to move to. The second and third preset angles refer to the target rotation angles that the upper baffle 103 and the lower baffle 104 need to achieve. The purpose of these preset angles and positions is to ensure that a preset, reasonable initial fit clearance is maintained between the upper and lower baffles and the diversion valve plate, avoiding interference and effectively preventing leakage.

[0065] Furthermore, the closed-loop control system, comprised of a control module, a detection module, and an angle compensation module, possesses anomaly detection and multi-level response strategies. The anomaly detection includes at least one of the following scenarios:

[0066] (a) Deviation exceeds standard: The channel opening size value monitored in real time deviates from the target preset value by more than 20%;

[0067] (b) Compensation failure: After the automatic fine-tuning compensation program executed by the angle compensation module driving the corresponding adjustment mechanism is performed twice or more, the monitored channel opening size still cannot be restored to the allowable range;

[0068] (c) Sudden changes: Monitoring data shows that the channel opening size changes at a rate exceeding 1 mm / s per unit time. This often indicates that the mechanical connection may be loose or the component may be abnormal.

[0069] When the closed-loop control system detects the above-mentioned abnormal state, the controller will immediately trigger an audible and visual alarm and display a message on the human-machine interface stating "Manual inspection required." If the alarm continues for a certain period of time (e.g., 5 minutes) without manual confirmation and handling, the closed-loop control system will activate a safety interlock, forcibly suspend the diversion operation, and enter a safe shutdown state to protect the safety of the equipment and products.

[0070] Furthermore, this invention introduces a gap recovery strategy based on collaborative compensation. When long-term operation causes micron-level wear on the rotation shaft of the diversion valve plate 102, and the adjustment mechanism of the upper baffle 103 or lower baffle 104 also has a small reverse gap, adjusting either mechanism alone may not be efficient in eliminating the channel deviation caused by the superposition. At this time, the angle compensation module will coordinate the first adjustment mechanism 105, the second adjustment mechanism 106, and / or the third adjustment mechanism 107 to perform linked fine-tuning. For example, the first adjustment mechanism 105 is instructed to slightly raise the diversion valve plate 102, while the second adjustment mechanism 106 is instructed to move the upper baffle 103 horizontally forward, so that the channel opening size can be quickly and accurately restored to the optimal state through multiple execution units. The closed-loop control system presets physical travel limits for the drive units of each adjustment mechanism (such as the first telescopic rod 1051, the upper lead screw module 1062, the lower lead screw module 1072, etc.). When the cumulative compensation amount approaches its preset limit, the closed-loop control system can determine that the wear of the corresponding mechanical component is nearing the end of its life, thereby triggering a predictive maintenance warning.

[0071] Example 3: To reduce the dependence of the closed-loop control system on the frequency and accuracy of real-time dynamic adjustment, and to enhance stability and leakage prevention under high-speed, continuous operation, this example optimizes the baffle end structure based on Example 1 or 2.

[0072] See Figure 11 and Figure 12 A first inclined surface 10302 is provided at the end of the upper baffle 103, that is, at the end near the diversion valve plate 102. A second inclined surface 10402 is provided at the end of the lower baffle 104, with the first inclined surface 10302 facing downwards and the second inclined surface 10402 facing upwards. At the same time, both ends of the diversion valve plate 102 are machined with inclined surfaces that match the first inclined surface 10302 and the second inclined surface 10402.

[0073] When the diversion valve plate 102 is flipped downwards to its limit position, for example, forming an upper channel, the inclined surface at its end is tightly fitted with the second inclined surface 10402 at the end of the lower baffle 104. When the diversion valve plate 102 is flipped upwards to its limit position to form a lower channel, the inclined surface at its end is tightly fitted with the first inclined surface 10302 at the end of the upper baffle 103. This inclined surface fitting structure forms a mechanical seal, which can effectively prevent the silicon steel sheet from leaking out from the end gap. To achieve a tight fit, the horizontal position of the upper baffle 103 or the lower baffle 104 can be finely adjusted by the corresponding upper screw module 1062 or lower screw module 1072.

[0074] After completing the flipping and positioning of the diversion valve plate 102 and the necessary preliminary channel adjustment, if the current channel is the upper channel, the lower lead screw module 1072 in the third adjustment mechanism 107 is driven to move the lower baffle 104 horizontally forward until the inclined surface at the end of the diversion valve plate 102 is tightly fitted with the second inclined surface 10402 at the end of the lower baffle 104; if the current channel is the lower channel, the upper lead screw module 1062 in the second adjustment mechanism 106 is driven to move the upper baffle 103 horizontally forward until the inclined surface at the end of the diversion valve plate 102 is tightly fitted with the first inclined surface 10302 at the end of the upper baffle 103. In subsequent operation, if loosening of the fit is detected or caused by mechanism retraction, the above steps can be repeated to eliminate the lateral gap again through horizontal movement.

[0075] See Figure 13 and Figure 14 This provides an alternative end structure for the upper baffle 103 and the lower baffle 104. A first stop block 10301 is provided at the end of the upper baffle 103, and its contact surface can be a flat surface or a slightly inclined surface. A second stop block 10401 is provided at the end of the lower baffle 104. The end of the diversion valve plate 102 can be designed accordingly.

[0076] like Figure 14 As shown, when the diversion valve plate 102 is flipped upwards, its end can abut against the lower surface of the first stop block 10301. The presence of the first stop block 10301 is equivalent to adding a contactable boss between the diversion valve plate 102 and the main body of the upper baffle 103, which can compensate for any vertical gap that may exist between them, thereby reducing the frequency of eliminating the vertical gap by simply adjusting the angle of the upper baffle 103. If a lateral gap occurs between the diversion valve plate 102 and the first stop block 10301, the upper lead screw module 1062 can be activated to drive the upper baffle 103 to move horizontally, so that the first stop block 10301 is in close contact with the end of the diversion valve plate 102, eliminating the lateral gap. The cooperation principle of the second stop block 10401 of the lower baffle 104 with the diversion valve plate 102 is similar.

[0077] After the diversion valve plate 102 is flipped and positioned, the adjustment mechanism corresponding to the currently effective channel is driven to perform a combined adjustment. If the current channel is the lower channel, the second telescopic rod 1064 in the second adjustment mechanism 106 is first driven to finely adjust the flip angle of the upper baffle 103 to optimize the vertical clearance; then the upper lead screw module 1062 is driven to move the upper baffle 103 horizontally until the first stop block 10301 at its end is in close contact with the end of the diversion valve plate 102, eliminating the lateral clearance. If the current channel is the upper channel, the third adjustment mechanism 107 is driven to perform a similar combined adjustment to ensure good fit between the end of the diversion valve plate 102 and the area of ​​the second stop block 10401.

[0078] In this structure, the first stop 10301 provides direct vertical clearance compensation, thus appropriately reducing the frequency and accuracy requirements for real-time angle fine-tuning of the second telescopic rod 1064.

[0079] Through any of the above schemes and corresponding methods, Embodiment 3 significantly reduces the absolute dependence of the closed-loop control system on real-time sensor feedback and high-frequency fine-tuning of the actuator on dynamic adjustment, thereby improving the anti-interference capability, stability and leak-proof reliability of the closed-loop control system during high-speed and long-term operation.
