Detailed Implementation Plan

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] In existing technologies, most reel-handling equipment requires removing the empty reel before feeding in a new one after the previous reel is consumed. With increasing equipment efficiency and production capacity requirements, the size and weight of the transported reels are increasing, and manual removal of empty reels is no longer feasible. Existing reel-changing devices can only transport one reel at a time. If the existing reel-changing device is used to disassemble and transport the empty reel, manual fine-tuning is often required, significantly reducing the efficiency of new reel replacement. This embodiment provides the following solution:

[0035] like Figures 1 to 3 As shown, a material roll changing device includes a support shaft 1, which has a main body connecting seat 11 connected to the lifting end of a lifting mechanism. The support shaft 1 has a new material roll carrying part 12 and an empty material roll carrying part 13. The new material roll carrying part 12 has a new material roll loading and unloading mechanism 2 that can move laterally, and the new material roll loading and unloading mechanism 2 has a telescopic centering clamping mechanism 3. The main body connecting seat 11 has an empty material roll gripping and unloading mechanism 4 along the direction of the empty material roll carrying part 13, and the empty material roll gripping and unloading mechanism 4 has a laterally movable pushing and picking mechanism 5.

[0036] It should be noted that the lowering mechanism is installed on the lateral moving mechanism. The lateral moving mechanism and the lifting mechanism adjust the up, down, left, and right positions of the bearing shaft 1, so that the new material roll bearing part 12 and the empty material cylinder bearing part 13 of the bearing shaft are aligned with the corresponding docking material shaft 6. When a new material roll needs to be replaced, the empty material cylinder gripping and unloading mechanism 4 moves the pushing and picking mechanism 5 to the appropriate position of the empty material cylinder 8, and the pushing and picking mechanism unloads the empty material cylinder 8 onto the empty material cylinder bearing part 13. After rotating the entire device 180 degrees, the new material roll 7 loaded on the new material roll bearing part 12 is clamped by the centering clamping mechanism 3, and then fed into the docking material shaft 6 by the new material roll loading and unloading mechanism 2.

[0037] In some embodiments, such as Figure 4As shown, the main connecting seat 11 includes a main load-bearing column 111, a bottom mounting plate 112, a lifting point area plate 113, and a side pressure plate 114. The bottom mounting plate 112 is connected to the bottom of the main load-bearing column 111, the lifting point area plate 113 is connected to the top of the main load-bearing column 111, and the side pressure plate 114 is connected to one side of the main load-bearing column 111. The main connecting seat 11 is mounted on the bearing shaft 1 via the main mounting plate 115.

[0038] It should be noted that the main load-bearing column 111 is based on profiles and connects the lifting mechanism and the entire device. High torque resistance ensures the stability of the entire device during use. The bottom mounting plate 112 is bolted to the main mounting plate 115, thereby fixing the load-bearing shaft 1 and bearing the main connection force during the use of the entire device. The lifting point area plate 113 is responsible for connecting the main load-bearing column 111 and the lifting device. This part ensures overall rigidity through welded stiffening plates and a reinforced structure after bolting, and uses an arc surface at the bottom as a connection to distribute internal stress. The side pressure plate 114 is fixed to one side of the main load-bearing column 111 with bolts. This area does not bear any load or connection, but has a wiring channel on the back through which some electrical cables will connect to the control terminal above.

[0039] In some embodiments, such as Figure 5 and Figure 6 As shown, the new material roll loading and unloading mechanism 2 includes a main frame 21. The main frame 21 is provided with a first moving mechanism 22. The first moving mechanism 22 includes a first slider 221 that is connected to a first slide rail 25 and a screw connecting seat 222 that is connected to the screw of the screw drive mechanism 26. First telescopic devices 23 are respectively provided on both sides of the main frame 21. The telescopic end of the first telescopic device 23 is connected to a pusher plate 24, and a centering clamping mechanism 3 is provided on the pusher plate 24.

[0040] It should be noted that the centering clamping mechanism 3 is used to clamp the new material roll, such as... Figure 7 As shown, when the lead screw drive mechanism 26 drives the lead screw to rotate, it drives the new material roll loading and unloading mechanism 2 to move laterally along the first slide rail 25 to perform the material pushing operation. The first telescopic device 23 adopts a square cylinder, such as... Figure 8 As shown, the first telescopic device 23 enables the pusher plate 24 to perform a second short-distance push operation, allowing the new material roll to be fully positioned, thereby improving the accuracy of the new material roll's positioning. Furthermore, when a new material roll needs to be gripped to the new material roll bearing section 12, the pusher plate 24 is moved to its maximum stroke by the screw drive mechanism 26, and then pushed out again by the first telescopic device 23. After the new material roll is clamped by the centering clamping mechanism 3, the pusher plate 24 is retracted by the screw drive mechanism 26 and the first telescopic device 23, placing the new material roll in the new material roll bearing section 12, thus improving the accuracy of gripping the new material roll.

[0041] In some embodiments, the main frame 21 includes side plates 211 connected to both sides of the pusher plate, a first telescopic device 23 is installed on one side of the side plate 211, and a slider seat 212 is connected to the other side of the side plate 211. The slider seats 212 are connected to each other by a connecting plate 213. A first slider 221 is installed on the slider seat 212, and a lead screw connecting seat 222 is installed on the connecting plate 213.

[0042] It should be noted that the slider seat 212 is made of sheet metal welded together, and its overall rigidity and stability are increased through reinforcing ribs and other structures. Specifically, the connecting plate 213 is connected to the slider seat 212 by bolts, and the first slider 221 is installed on the slider seat 212 by bolts.

[0043] In some embodiments, the centering clamping mechanism 3 includes a second telescopic device 31, with clamping arms 32 rotatably connected to both ends of the second telescopic device 31. The clamping arms 32 are rotatably connected to the pusher plate 24, and a clamping block 321 is connected to the clamping end of the clamping arm 32.

[0044] Specifically, the second telescopic device 31 adopts a circular cylinder. When the telescopic end of the circular cylinder extends or retracts, it drives the clamping arm 32 to rotate and swing at the rotation point connected to the pusher plate 24. The clamping arm 32 moves towards the center, thereby clamping the new material roll.

[0045] In some embodiments, the pusher plate 24 is provided with left and right symmetrical rotating columns 244, and the clamping arm 32 is rotatably connected to the rotating columns 244.

[0046] It should be noted that the rotating column 244 separates the clamping arm 32 from the pusher plate 24, thus preventing interference between the clamping arm 32 and the pusher plate 24 during the rotational clamping process and improving the accuracy of clamping new material rolls. Furthermore, the symmetrically arranged rotating columns 244 ensure that the force is evenly distributed on both sides when the new material roll is clamped by the clamping arm 32, achieving a centered clamping function, ensuring that the new material roll bearing part 12 is located in the center of the new material roll.

[0047] In some embodiments, the pusher plate 24 is provided with a limiting block 241 for limiting the clamping arm 32. The limiting block 241 is located on both sides of the clamping arm, thereby limiting the extension and retraction stroke of the second telescopic device 31 and controlling the rotation, swing and floating of the clamping arm 32 within a preset range of activity.

[0048] In some embodiments, the bottom of the pusher plate 24 is provided with an arc-shaped cutout 242 corresponding to the material roll, and the pusher plate 24 is provided with pusher blocks 243 located on both sides and the top of the arc-shaped cutout 242 respectively.

[0049] It should be noted that the pusher block 243 comes into contact with the new roll of material during the pushing process, and plays a role in buffering and wear resistance.

[0050] In some embodiments, such as Figure 9 and Figure 10 As shown, the first slide rails 25 are respectively disposed on both sides of the new material roll carrier 12, and the lead screw drive mechanism 26 is disposed at the bottom of the new material roll carrier 12. A servo motor driver 16 is installed below the empty material cylinder carrier 13. Both the new material roll carrier 12 and the empty material cylinder carrier 13 are provided with guide heads 14, which have a frustum-shaped structure and are equipped with a positioning detection mechanism 141 and a vision positioning mechanism 142. Rollers 15 arranged linearly are provided directly above and diagonally above both sides of the new material roll carrier 12 and the empty material cylinder carrier 13.

[0051] It should be noted that the servo motor driver 16 serves as the control intermediary for all operations related to the entire device. The tapered structure of the inclined surface of the guide head 14 is used for guidance and aiming, assisting in connecting the new material roll carrier 12 or the empty material cylinder carrier 13 to the docking shaft, thereby improving docking accuracy. The positioning detection mechanism 141 is used to ensure complete docking with the docking shaft. Using distance sensor logic control, it ensures complete docking before subsequent operations, such as releasing the material roll or pushing the material, can be performed. The visual positioning mechanism 142, composed of an image acquisition unit and an image analyzer, is used for automated control of the entire device in six directions (front, back, left, right, up, and down) through real-time image acquisition and analysis. This ensures the device is aligned with the center of the docking shaft within a certain range. During the insertion and docking process, fine adjustments can also be made using the guide head 14.

[0052] In some embodiments, distance sensors are installed at both the beginning and end of the first slide rail 25 to detect the moving position of the new material roll loading and unloading mechanism 2, thereby controlling the driving stroke of the lead screw drive mechanism 26 and playing a limiting role.

[0053] In some embodiments, such as Figure 11 and Figure 12 As shown, the empty material cylinder gripping and unloading mechanism 4 includes a cantilever frame 41, which has a channel steel structure. The cantilever frame 41 is connected to the main body connecting seat 11 through the cantilever frame mounting plate 43. The cantilever frame 41 is provided with a second moving mechanism 42 that causes the material pushing and picking mechanism 5 to move twice the stroke. The material pushing and picking mechanism 5 is connected to the moving end of the second moving mechanism 42. The material pushing and picking mechanism 5 is provided with a fixing device 51 for fixing the empty material cylinder.

[0054] In some embodiments, the second moving mechanism 42 includes a linear drive device 421, a moving base 422, a second slide rail 423, a second slider, a third slide rail 425, and a third slider. The linear drive device 421 is mounted on the top of the cantilever frame 41, and the moving base 422 is connected to the drive end of the linear drive device 421. The second slider is connected to the bottom of the cantilever frame 41, the second slide rail 423 is connected to the second slider, the third slide rail 425 is connected to the second slide rail 423, and the third slider is connected to the third slide rail 425. The bottom of the moving base 422 is connected to the third slide rail 425, and the material pushing and picking mechanism 5 is connected to the third slider. A rotatable main synchronous wheel 427 is mounted on one side of the moving base 422, and a synchronous wheel mounting plate 4251 is connected to the end of the third slide rail 425. A rotatable secondary synchronous wheel 428 is mounted on the synchronous wheel mounting plate 4251, and the main synchronous wheel 427 is connected to the secondary synchronous wheel 428 via a synchronous belt 429. The end of the cantilever 41 is connected to a first clamp 411, which is connected to the timing belt 429. The material pushing and picking mechanism 5 is provided with at least one second clamp 52, which is connected to the timing belt 429.

[0055] It should be noted that the linear drive unit 421 uses a linear cylinder, such as Figure 13 and Figure 14 As shown, when the linear cylinder causes the moving seat 422 to move forward laterally, the moving seat 422 drives the second slide rail 423, the third slide rail 425, the main synchronous pulley 427, the auxiliary synchronous pulley 428, and the synchronous belt 429 to move forward together. At this time, the first clamp 411 acts as a fulcrum. After being subjected to the forward force of the synchronous belt 429, the main synchronous pulley 427 and the auxiliary synchronous pulley 428 rotate, driving the synchronous belt 429 to move. Thus, the material pushing and picking mechanism 5 is driven to move by the moving seat 422 and also by the synchronous belt 429, that is, double the stroke, realizing full coverage of the pusher stroke.

[0056] Similarly, when the pushing and picking mechanism 5 finishes pushing the cylinder forward and needs to pick it up, the linear cylinder causes the moving seat 422 to move laterally backward. The moving seat 422 then drives the second slide rail 423, the third slide rail 425, the main synchronous pulley 427, the auxiliary synchronous pulley 428, and the synchronous belt 429 to move backward together. At this time, the first clamp 411 acts as a fulcrum, and under the force of the synchronous belt 429, the main synchronous pulley 427 and the auxiliary synchronous pulley 428 rotate, driving the synchronous belt 429 to move. Thus, the pushing and picking mechanism 5 is moved by the moving seat 422 and simultaneously by the synchronous belt 429, resulting in double the stroke and achieving full coverage of the cylinder picking stroke.

[0057] In some embodiments, the movable seat 422 includes a top sheet metal 4221 and a side sheet metal 4222, the side sheet metal 4222 being connected to both sides of the top sheet metal 4221 respectively, and the side sheet metal 4222 being formed by bending the top sheet metal 4221.

[0058] In some embodiments, the fixing device 51 adopts a lifting cylinder, which pushes out and fixes the empty material cylinder, thereby preventing slippage during the pushing or taking out of the cylinder, making it more stable and reliable.

[0059] In some embodiments, the material pushing and picking mechanism 5 includes a movable frame 53, and a second clamp 52 is connected to one side of the movable frame 53. The number of second clamps 52 is set to two. A fixing device 51 is installed at one end of the movable frame 53, and a pusher block 54 is installed at the other end of the movable frame 53. The pusher block 54 is vertically arranged and plays a role in buffering and wear resistance during the pushing process.

[0060] In summary, the embodiments of this utility model provide a material roll changing device, which sets a new material roll loading and unloading mechanism and an empty material cylinder gripping and unloading mechanism at both ends of the bearing shaft, so that when changing material rolls, the empty material cylinder can be unloaded first by the empty material cylinder gripping and unloading mechanism and then the new material roll loading and unloading mechanism can be used to load the material roll, which greatly improves the efficiency of material roll changing and reduces labor costs.
