Abstract
Description
Technical Field
[0001] This invention relates to the field of composite material molding equipment technology, specifically to a storage device and method for SMC sheets. Background Technology
[0002] In the automated production of SMC sheets, stacking and storing the finished sheets is a crucial process. Traditional storage methods often use a swing-type feeding device to stack the sheets in a "Z" shape in the receiving box.
[0003] However, existing oscillating unloading devices have many drawbacks. First, during the oscillating descent, the edges of the sheet are prone to drifting and curling, resulting in wrinkles and uneven stacking, which affects the quality of subsequent automated transportation and molding. Second, for continuous SMC sheets, existing devices lack a precise length control mechanism, making it impossible to achieve automated stacking of fixed length and area. They still rely on manual intervention or subsequent cutting, resulting in low efficiency and unreliable accuracy.
[0004] Therefore, it is essential to design a practical storage device and method for SMC sheets that can be stacked at fixed lengths. Summary of the Invention
[0005] The purpose of this invention is to provide a storage device and method for SMC sheets to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a storage device and method for SMC sheet, comprising a feeding device and a swinging device. The feeding device consists of a conveying mechanism and a frame. The conveying mechanism is Z-shaped for feeding and is bolted to the frame. A discharging device is provided on the right side of the feeding device. One end of the feeding device is connected to the bearing of the swinging device. Servo motors are fixed on both sides of the feeding device. The output shaft of the servo motor is fixedly connected to one end of the swinging device. A cylinder is fixedly connected to the middle of both sides of the swinging device. A U-shaped block is fixedly connected above the cylinder. The cross-section of the U-shaped block is inverted U-shaped. A compensation roller is connected to the bearing at the lower end of the corresponding side of the two sets of U-shaped blocks. The compensation roller is used to compensate for the sheet with uneven thickness and to compress the uneven parts to a standard value.
[0007] According to the above technical solution, the swing device has a bearing connected to several guide rods to guide the SMC sheet to fall. Laser rangefinders are fixedly connected to the inner sides of both sides above the swing device to measure the thickness of the sheet in real time without contact. A drop box is provided below the swing device to collect the falling sheet.
[0008] According to the above technical solution, the lower end of the swing device is bolted to a slide rail, and two sets of sliders are slidably connected on the slide rail. Each set of sliders is fixedly connected to a fixed plate on the other side away from the slide rail. The lower end of the fixed plate is connected to a rotating rod by a bearing. An industrial camera is fixedly connected to both ends of the slide rail for detecting the thickness of the sheet material after passing through the rolling wheel.
[0009] According to the above technical solution, a rolling assembly is connected to the bearing at the lower end of the fixed plate. The rolling assembly includes a guide block one and a guide block two. The top bearings of the guide blocks one and two are connected to the rolling roller one and the rolling roller two. A pressure sensor one is provided at the connection between the guide block one and the rolling roller one, and a pressure sensor two is provided at the connection between the guide block two and the rolling roller two. When the sheet passes through the rolling assembly, it will generate a reverse force on the rolling roller one and the rolling roller two, thereby detecting the tension of the sheet so as to adjust the tension in real time.
[0010] According to the above technical solution, the guide block 1 is internally threaded with a threaded rod 1, and the guide block 2 is internally threaded with a threaded rod 2. The right end of the threaded rod 1 is fixedly connected to the threaded rod 2. The threads of the threaded rod 1 and the threaded rod 2 have opposite directions. The left end of the threaded rod 1 is fixedly connected to the rotating rod. When the threaded rod 1 and the threaded rod 2 rotate, the guide blocks 1 and 2, which are threaded to them, move closer or further away synchronously, and the spacing is adjusted according to the thickness of the sheet.
[0011] According to the above technical solution, a micro motor is fixedly connected to the lower end of the fixed plate on the side away from the rotating rod. The output end of the micro motor is fixedly connected to the rotating rod and is used to control the distance between the first and second rolling rollers. When the micro motor is driven to operate, it drives the rotating rod to rotate, thereby driving the first and second threaded rods to rotate.
[0012] According to the above technical solution, an industrial camera 2 is fixedly connected to the side of the frame facing the feeding box for detecting the length of the sheet falling into the feeding box. A cutting platform is fixedly connected above the conveying mechanism. A fixing block is fixedly connected above the cutting platform. Support columns and support plates 1 are fixedly connected to both ends of the cutting platform. The support columns are set on both sides of the support plates 1. A support plate 2 is fixedly connected above each set of support columns and support plates 1. A cylinder 2 is fixedly connected above the support plate 2. The push rod of the cylinder 2 passes through the support plate 2 and is fixedly connected to a moving table.
[0013] According to the above technical solution, the cross-section of the moving platform is T-shaped. A blade is fixed at the lower end of the moving platform facing the swing device. The length of the blade is slightly less than the length of the moving platform. A sliding rod is bolted to the upper part of the side of the moving platform away from the swing device. A pressure block is fixedly connected below the sliding rod.
[0014] According to the above technical solution, each of the two sets of support plates has a slide rail 2 fixedly connected to one side. Each slide rail 2 has a slider 2 slidably connected to it. The corresponding sides of the two sets of sliders 2 are fixedly connected to the moving table. A drive roller is connected to the two sets of support plates via a bearing. A micro motor 2 is keyed to one end of the drive roller and fixedly connected to one side of the feeding device. A through groove is provided on each of the two sets of support plates, located above the connection between the drive roller and the support plate. A slider 3 is slidably connected inside the groove. A driven roller is connected to the inside of slider 3 via a bearing. A threaded rod 3 is threadedly connected above the groove. A knob is fixedly connected above the threaded rod 3, with anti-slip textures around its surface to increase friction. The lower end of the threaded rod 3 contacts the slider 3. When the knob is rotated clockwise, the threaded rod 3 rotates and moves downward, thus pressing down the slider and fixing the distance between the drive roller and the driven roller, allowing for the crushing of the passing sheet.
[0015] According to the above technical solution, the following operational steps are included: Step 1: Load the material and identify and compensate for its thickness; Step 2: Unloading, checking if the length of the sheet in the unloading box meets the requirements, and making adjustments accordingly; Step 3: Readjust the sheet material that caused the compensation problem; Step 4: Adjust the oscillation speed for sheets that are thinner than normal.
[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: by setting a compensation roller, the present invention can correct the sheet with uneven thickness before the sheet reaches the rolling roller, thereby improving the overall quality of the sheet and making it more neat when stored.

[0018] 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.
[0019] Please see Figure 1-7 The present invention provides a technical solution: a storage device and method for SMC sheet material, including a feeding device 1 and a swinging device 2. The feeding device 1 is composed of a conveying mechanism 42 and a frame 43. The conveying mechanism 42 is Z-shaped for feeding and is bolted to the frame 43. A feeding device 44 is provided on the right side of the feeding device 1. The feeding device 44 is composed of a feeding roll and a driving device, which is prior art and will not be described in detail. One end of the feeding device 1 is connected to the swinging device 2 by a bearing. Servo motors 31 are fixed on both sides of the feeding device 1. The output shaft of the servo motor 31 is fixedly connected to one end of the swinging device 2. A cylinder 4 is fixedly connected in the middle of both sides of the swinging device 2. A U-shaped block 5 is fixedly connected above the cylinder 4. The cross-section of the U-shaped block 5 is inverted U-shaped. A compensation roller 18 is connected to the lower end of the corresponding side of the two sets of U-shaped blocks 5. The compensation roller 18 is used to compensate for the sheet material with uneven thickness and squeeze the uneven parts into a standard value. The swing device 2 is connected to a bearing with several guide rods 3 to guide the SMC sheet to fall. Laser rangefinders 7 are fixedly connected to the inner sides of both sides above the swing device 2 to measure the thickness of the sheet in real time without contact. A drop box 8 is provided below the swing device 2 to collect the falling sheet. The lower end of the swing device 2 is bolted to a slide rail 19. Two sets of sliders 20 are slidably connected to the slide rail 19. Each set of sliders 20 is fixedly connected to a fixed plate 21 on the other side away from the slide rail 19. The lower end of the fixed plate 21 is connected to a rotating rod 23 by a bearing. The two ends of the slide rail 19 are fixedly connected to an industrial camera 6 for detecting the thickness of the sheet material after passing through the rolling wheel. The lower end of the fixed plate 21 is connected to the bearing of the rolling assembly 22. The rolling assembly 22 includes a guide block 1 26 and a guide block 27. The top bearings of the guide block 1 26 and the guide block 27 are connected to the rolling wheel 1 28 and the rolling wheel 29. A pressure sensor 1 is provided at the connection between the guide block 1 26 and the rolling wheel 1 28, and a pressure sensor 2 is provided at the connection between the guide block 27 and the rolling wheel 29. When the sheet passes through the rolling assembly 22, the sheet will generate a reverse force on the rolling wheel 1 28 and the rolling wheel 29, thereby detecting the tension of the sheet so as to adjust the tension in real time. Guide block 1 26 is internally threaded with threaded rod 1 24, and guide block 2 27 is internally threaded with threaded rod 25. The right end of threaded rod 1 24 is fixedly connected to threaded rod 25. The threads of threaded rod 1 24 and threaded rod 25 have opposite directions. The left end of threaded rod 1 24 is fixedly connected to rotating rod 23. When threaded rod 1 24 and threaded rod 25 rotate, guide block 1 26 and guide block 27, which are threaded to them, move closer or further away synchronously, and the spacing is adjusted according to the sheet thickness. A micro motor 30 is fixedly connected to the lower end of the fixed plate 21 on the side away from the rotating rod 23. The output end of the micro motor 30 is fixedly connected to the rotating rod 23 and is used to control the distance between the first rolling wheel 28 and the second rolling wheel 29. When the micro motor 30 is driven to operate, it drives the rotating rod 23 to rotate, thereby driving the threaded rod 24 and the second threaded rod 25 to rotate. An industrial camera 2 41 is fixedly connected to the side of the frame 43 facing the material box 8 for detecting the length of the sheet falling into the material box 8. A cutting platform 9 is fixedly connected above the conveying mechanism 42. A fixing block 45 is fixedly connected above the cutting platform 9. Support columns 10 and support plates 11 are fixedly connected to both ends of the cutting platform 9. The support columns 10 are set on both sides of the support plates 11. A support plate 2 12 is fixedly connected above each set of support columns 10 and support plates 11. A cylinder 2 13 is fixedly connected above the support plate 2 12. The push rod of the cylinder 2 13 passes through the support plate 2 12 and is fixedly connected to a moving table 14. The moving platform 14 has a T-shaped cross section. A blade 15 is fixed to the lower end of the moving platform 14 facing the swing device 2. The length of the blade 15 is slightly less than the length of the moving platform 14. A sliding rod 16 is bolted to the upper side of the moving platform 14 away from the swing device 2. A pressure block 17 is fixedly connected to the lower part of the sliding rod 16. Two sets of support plates 11 are fixedly connected to slide rails 32 on their respective sides. Each set of slide rails 32 is slidably connected to sliders 33. The corresponding sides of the two sets of sliders 33 are fixedly connected to the moving table 14. A drive roller 34 is connected between the two sets of support plates 11 by a bearing. A micro motor 35 is keyed to one end of the drive roller 34. The micro motor 35 is fixedly connected to one side of the feeding device 1. Two sets of support plates 11 are provided with through grooves 36. The grooves 36 are located above the connection between the drive roller 34 and the support plate 11. A slider 37 is slidably connected inside the grooves 36. A driven roller 38 is connected to the bearing inside the slider 37. A threaded rod 39 is threadedly connected above the grooves 36. A knob 40 is fixedly connected above the threaded rod 39. The knob 40 is provided with anti-slip texture to increase friction. The lower end of the threaded rod 39 is in contact with the slider 37. When the knob 40 is rotated clockwise, it drives the threaded rod 39 to rotate and move downward, thereby pressing down the slider 37, thus fixing the distance between the drive roller 34 and the driven roller 38, and crushing the passing sheet.
[0020] Working principle: The SMC sheet is fed from the feeding device 44 onto the loading device 1, and then transported by the conveying mechanism 42 to the swing device 2. The sheet thickness parameters are set, and the driving cylinder 4 operates to automatically adjust the distance between the compensating roller 18 and the guide rod 3. The industrial camera 6 detects the sheet width and automatically adjusts the spacing between the two sets of rolling components 22 on the slide rail 19, ensuring that the overall working range of the rolling components 22 is adapted to the sheet width. Then, based on the sheet thickness, the micro motor 30 is driven. Because the threads of the threaded rods 24 and 25 have opposite directions, the guide blocks 26 and 27 will move synchronously towards or away from each other, thereby precisely adjusting the clamping distance between the rolling rollers 28 and 29, causing them to make slight contact with the sheet surface and generate appropriate pressure, thus smoothing and effectively preventing wrinkles during material drop.
[0021] After a material box 8 finishes collecting material, the knob 40 is manually tightened so that the threaded rod 39 contacts the slider 37 and is pressed down, thereby reducing the distance between the driving roller 34 and the driven roller 38, which has a flattening effect. All devices stop working, and then the cylinder 2 13 is started to move the moving table 14 down, thereby moving the blade 15 down to cut the sheet. At the same time, the pressure block 17 provides an auxiliary force so that the blade 15 can cut the sheet more completely.
[0022] A method for storing SMC sheets includes the following steps: Step 1: Load the material and identify and compensate for its thickness.
[0023] Specifically, the feeding device 44 unwinds the sheet onto the feeding device 1, which then transports it. Before the sheet reaches the rolling assembly 22, the sheet thickness uniformity is checked. The laser range sensor 7 identifies whether the sheet thickness is uniform. If it is uniform, the distance between the rolling roller 1 28 and the rolling roller 29 is adjusted according to the sheet thickness. If it is not uniform, the cylinder 1 4 adjusts the distance between the compensating roller 18 and the guide rod 3, and the compensating roller 18 is used to compensate for it once. Then, the sheet is transported to the rolling assembly 22 for swinging drop. A fixed length A is set according to the length of the drop box 8 to ensure that the length in the drop box 8 is consistent each time. Let the actual drop length be B.
[0024] Step 2: Unloading, checking whether the length of the sheet in unloading box 8 meets the requirements and making adjustments.
[0025] Specifically, after the first swing-and-drop operation, industrial camera 41 scans the length of the sheet material falling into the dropping box 8. If A=B, the swing-and-drop operation continues; if A≠B, consider the possibility of mismatched swing arm amplitude and insufficient or excessive compensation causing inconsistent dropping lengths. First, determine if the mismatched swing arm amplitude is the cause. Industrial camera 41 scans the height from the top of the sheet material in the dropping box 8 to the top of the dropping box 8. If the height is within half the height of the dropping box 8, increase the swing amplitude; if the height exceeds half the height of the dropping box 8, appropriately decrease the swing amplitude, and then repeat the dropping process. When A=B, it is determined that the mismatched swing arm amplitude is the cause.
[0026] Step 3: Make further adjustments to the sheets that caused the compensation problem.
[0027] Specifically, when A≠B, it is determined that the inconsistent length is caused by insufficient or excessive compensation. The sheet is pulled back to its original position, and the laser rangefinder 7 scans the sheet thickness at the rolling assembly 22. If the sheet thickness is still greater than the normal thickness, it is compensated again until the sheet delivered to the rolling assembly 22 is equal to the normal value before being dropped. If the sheet thickness is less than the normal thickness, it means that the gap between the compensation rollers 18 is too small, which has rolled the sheet to a value less than the normal value. The gap between the compensation rollers 18 is increased and the sheet is held for 2 seconds to restore its original thickness before being dropped.
[0028] Step 4: Adjust the oscillation speed for sheets that are thinner than normal.
[0029] Specifically, for sheets that are thinner than normal and will not return to normal thickness, when the laser rangefinder detects a point where the sheet thickness is less than normal, the oscillation speed of the servo motor 31 is appropriately reduced to prevent the sheet from shifting due to excessive speed.
[0030] It should be added that after each feeding is completed, the length of the sheet falling into the feeding box 8 is checked to ensure that the sheet is stacked layer by layer during each feeding, so that the stacked area is the same each time.
