Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and more specifically, to a conveying device for loading and unloading anti-scratch fireproof blanket rolls. Background Technology

[0002] Fire blankets are mostly stored and transported in roll form. The rolls have hollow paper tubes or metal inner tubes inside. Before and after the cutting or packaging process is completed on the production line, conveyor robots are needed to complete the loading and unloading of the fire blanket rolls.

[0003] Existing fire blanket roll material loading and unloading conveying equipment is generally equipped with gantry robots to complete workpiece handling. The robot's gripping and positioning structure mostly uses support components with fixed spacing. The opening and closing stroke of the support components is controlled by a preset program, which has many limitations in actual use.

[0004] Because the width specifications of different batches of fire blanket rolls are not uniform during processing, there are deviations in the tightness of the roll winding and the coaxiality of the inner cylinder. Fixed-stroke clamping structures are difficult to adapt to roll workpieces of various sizes. When the robotic arm grips the roll, the feed rate of the side support components is prone to deviation, resulting in uneven force on the roll and displacement. The workpiece cannot be kept centered after gripping, and it is prone to shaking or slipping during transport, affecting the stability of loading and unloading operations. Conventional clamping methods rely on rigid support plates directly pressing against the inner wall of the roll's inner cylinder for fixation. The rigid components directly squeeze the inner cylinder of the fire blanket, which can easily scratch the cylinder wall or deform it when the force is concentrated. Once the inner cylinder of the roll is damaged, the entire fire blanket will loosen and scatter, causing material loss.

[0005] Existing gantry robots lack a follow-up centering adjustment structure in their gripping mechanisms. After the workpiece is loaded and positioned, the opening and closing actions of the gripping ends are independent, and the supporting structures on both sides cannot guarantee synchronous feeding. Each time the roll material specification is changed, the robot's operating parameters need to be manually recalibrated, making the debugging process cumbersome and taking up production line time. Some gripping structures rely solely on mechanical latches for locking and positioning, resulting in hard contact between the supporting components and the inner wall of the roll material. This makes it difficult to flexibly control the gripping force; insufficient gripping force will cause slippage and loosening, while excessive gripping force can easily damage the substrate.

[0006] In view of this, we propose a scrape-resistant fireproof blanket roll material loading and unloading conveying device. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the design of telescopic components, limiting components, connecting components, and sensing mechanisms, pre-calibrates the position using the sensing mechanism, ensuring precise alignment of the two side support columns with the ends of the fire blanket roll. Simultaneously, a motor-driven gear drives the two side toothed plates to move synchronously and equidistantly towards each other, achieving coordinated feeding of the double-sided clamping structure. Compared to traditional clamping structures with fixed strokes and independent single-sided movements, this device can adaptively adjust the clamping distance according to different widths of fire blanket rolls, effectively compensating for deviations in roll width, winding tightness, and inner cylinder coaxiality between different batches. It ensures automatic centering of the roll throughout the process, eliminating workpiece offset or unstable clamping caused by uneven feeding on both sides, avoiding shaking and slippage during transport, and significantly improving the overall stability of the roll loading and unloading process.

[0019] 2. This invention also incorporates a telescopic component, a connecting component, and a supporting component. Because the device features an airbag structure on the outside of the support plate, the sliding rod compresses the air inside the sliding sleeve, introducing the gas through the air inlet and hose into the airbag, causing it to inflate. This eliminates the traditional method of clamping the inner cylinder of the roll material by directly pressing it against a rigid support plate. The flexible airbag adheres to the inner wall of the support roll material, effectively dispersing the clamping pressure and preventing scratches or deformation of the inner cylinder caused by concentrated compression from rigid components. It also prevents the roll material from loosening due to damage to the inner cylinder, effectively reducing material loss. Furthermore, the inflated airbag increases the contact area, further enhancing the clamping and supporting effect.

[0020] 3. The present invention also designs a drive component. The device adopts a mechanical synchronous structure with gear and toothed plate linkage. The clamping stroke on both sides is always consistent. There is no need for manual calibration and adjustment of the robot parameters when changing different specifications of roll material. This greatly reduces the downtime of equipment debugging, improves the continuous operation efficiency of the production line, and is suitable for the batch loading and unloading production needs of multi-specification fire blanket roll material. The entire centering and clamping action is triggered by mechanical structure linkage, without the need for complex electrical control, thereby reducing the difficulty of using the device.

[0023] like Figures 1 to 10As shown, the present invention relates to a scrape-resistant fireproof blanket roll material loading and unloading conveying device, which includes a frame mechanism 1, a conveying mechanism 2 and a plurality of sensing mechanisms 3, wherein the frame mechanism 1 is connected to the conveying mechanism 2, and the plurality of sensing mechanisms 3 are arranged above the conveying mechanism 2. The conveying mechanism 2 includes a drive assembly 21, an external motor connected to the drive assembly 21, movable components 22 located on both sides of the drive assembly 21, two telescopic components 23 connected to the two movable components 22, a limiting component 24 located within the telescopic components 23, a connecting component 25, and multiple support components 26. The connecting component 25 is located within the telescopic component 23, and the multiple support components 26 are respectively connected to the connecting components 25 on both sides. By designing the telescopic component 23, the limiting component 24, the connecting component 25, and the sensing mechanism 3, the position is pre-calibrated, enabling the support columns 251 on both sides to accurately align with the anti-corrosion system. The fire blanket roll is aligned at both ends, and the gear 212 driven by the external motor drives the toothed plates 222 on both sides to move synchronously and at equal distances towards each other, realizing the linkage feeding of the double-sided clamping structure. Compared with the traditional clamping structure with fixed stroke and independent action on one side, this device can adaptively adjust the clamping distance according to the width of the fire blanket roll, effectively making up for the deviation problems of different batches of roll width, winding tightness and inner cylinder coaxiality. It ensures that the roll is automatically centered and positioned throughout the process, eliminates the workpiece offset and clamping instability caused by uneven feeding on both sides, avoids shaking and slipping during the transfer process, and greatly improves the overall stability of the roll loading and unloading process.

[0024] In an embodiment of the present invention, the frame mechanism 1 includes a truss 11. A first adjustment component 12 is disposed above the truss 11. An installation platform 14 is fixedly connected to one side of the first adjustment component 12. A second adjustment component 13 is fixedly connected above the installation platform 14. The installation platform 14 is slidably connected to the truss 11 via the first adjustment component 12. The two sides of the drive component 21 are slidably connected to two movable components 22 respectively. The two movable components 22 are fixedly connected to two telescopic components 23 respectively. The inner walls of the two telescopic components 23 are fixedly connected to two limiting components 24 respectively. One side of the inner wall of the two telescopic components 23 is fixedly connected to two connecting components 25 respectively. The two connecting components 25 are hinged to multiple support components 26 respectively. The drive component 21 is fixedly connected below the second adjustment component 13. Four sensing mechanisms 3 are fixedly connected to the four corners above the drive component 21 respectively. The sensing mechanism 3 includes a signal acquisition module 31. The output end of the signal acquisition module 31 is connected to a verification module 32 and a working condition alarm respectively. Module 38 is electrically connected, and the output of the verification module 32 is electrically connected to the screening module 33. The screening module 33 is electrically connected to the calculation module 37, the identification module 34, and the working condition alarm module 38. The calculation module 37 is electrically connected to the working condition alarm module 38. The identification module 34 is electrically connected to the judgment module 35 and the working condition alarm module 38. The judgment module 35 is electrically connected to the compensation output module 36 and the working condition alarm module 38. The working condition alarm module 38 is electrically connected to the specification storage module 39. Through the design of the drive component 21, the device adopts a mechanical synchronous structure with gear 212 and toothed plate 222 linkage. The clamping stroke on both sides is always consistent. There is no need for manual calibration and debugging of the robot parameters when changing different specifications of rolls. This greatly reduces the downtime of equipment debugging, improves the continuous operation efficiency of the production line, and is suitable for the batch loading and unloading production needs of multi-specification fire blanket rolls. The entire centering and clamping action is triggered by mechanical structure linkage, without the need for complex electrical control, thus reducing the difficulty of using the device. By designing the telescopic component 23, connecting component 25, and supporting component 26, the device features an airbag 265 structure on the outside of the supporting plate 263. The sliding rod 233 slides and compresses the air inside the sliding sleeve 231, guiding the gas through the air inlet 252 and hose 266 into the airbag 265, causing it to inflate. This eliminates the traditional method of clamping the inner cylinder of the roll material by directly pressing the rigid supporting plate 263 against it. The flexible airbag 265 adheres to the inner wall of the supporting roll material, effectively dispersing the clamping pressure and preventing scratches or deformation of the inner cylinder caused by concentrated compression from rigid components. It also prevents the roll material from loosening due to damage to the inner cylinder, effectively reducing material loss. Furthermore, the inflated airbag 265 increases the contact area, further enhancing the clamping and supporting effect.

[0025] In an embodiment of the present invention, the drive assembly 21 includes a mounting frame 211, within which a gear 212 is rotatably connected. Guide grooves 213 are provided above and below the left and right sides of the mounting frame 211. An external motor is fixedly connected to the rear of the mounting frame 211. The upper part of the mounting frame 211 is fixedly connected to the second adjustment assembly 13. The output end of the external motor is connected to the gear 212 via a transmission connection. The movable assembly 22 includes a side frame 221. A toothed plate 222 and a guide plate 223 are fixedly connected to one side of the side frame 221, and a side plate 224 is fixedly connected to the other side of the side frame 221. Plate 222 meshes with gear 212, and guide plate 223 is slidably connected in guide groove 213. The device adopts a mechanical trigger unfolding structure. The sliding sleeve 231 slides relative to the sliding rod 233 to drive the limiting cylinder 241 to move, thereby releasing the limiting constraint on the support plate 263. This allows the coil spring 264 to drive the rotator 261 and the support plate 263 to automatically unfold outward, achieving multi-point support and fixation of the inner cylinder. This improves the linkage effect of the overall structure of the device and can complete automatic tensioning and positioning without the need for additional drive components. The structure is simple and reliable, reducing equipment manufacturing and subsequent maintenance costs.

[0026] In another embodiment of the present invention, the telescopic component 23 includes a sliding sleeve 231, a sealing plate 232 slidably connected inside the sliding sleeve 231, a sliding rod 233 fixedly connected to one side of the sealing plate 232, a spring 234 fixedly connected to the other side of the sealing plate 232, a push plate 235 fixedly connected to the outside of the sliding rod 233, and the other end of the spring 234 fixedly connected to one side of the inner wall of the sliding sleeve 231. The sliding sleeve 231 is fixedly connected to the side plate 224. The limiting component 24 includes a limiting cylinder 241, a sliding groove 242 is provided on one side of the limiting cylinder 241, and a conical groove 243 is provided on the inner wall of the side of the limiting cylinder 241 where the sliding groove 242 is provided. The limiting cylinder 241 is fixedly connected inside the sliding rod 233. The connecting component 25 includes a support column 251, a plurality of air inlets 252 are provided on the outside of the support column 251, and a through hole 253 is provided inside the support column 251. The through hole 253 is connected to multiple air inlets 252. Multiple mounting slots 254 are provided on the outside of the support column 251. Each mounting slot 254 is equipped with a magnetic plate 255. One end of the support column 251 is fixedly connected to one side of the inner wall of the sliding sleeve 231. The air inlets 252 of the support column 251 are located inside the sliding sleeve 231. By opening a sliding groove 242 on the outside of the limiting cylinder 241, the limiting cylinder 241 can be easily aligned when entering the fire blanket roll, and damage to both sides of the fire blanket roll is avoided due to compression. At the same time, a conical groove 243 and an inclined groove on one side of the support plate 263 are provided to ensure that the limiting cylinder 241 can first be initially reset by pressing the support plate 263 when resetting, and then the inclined groove on one side of the support plate 263 is pressed to ensure that it is fully reset, which improves the stability of the device during use.

[0027] In another embodiment of the present invention, the support assembly 26 includes a plurality of rotators 261, which are respectively disposed at both ends of the support rod 262. Each rotator 261 includes a bearing and a shaft. A coil spring 264 is sleeved on the rotator 261. The support rod 262 is hinged to the support plate 263 through the rotators 261. A plurality of airbags 265 are disposed outside the support plate 263. The inner wall of the support rod 262 is connected to a hose 266. A magnetic patch is disposed outside the hose 266. The rotator at the other end of the support rod 262... 261 is snapped into the mounting slot 254. A slanted groove is provided on one side of the support plate 263. The other end of the flexible hose 266 is connected to the through hole 253. The flexible hose 266 is magnetically attached to the magnetic plate 255 located inside the support column 251 via a magnetic patch. The signal acquisition module 31 is used to acquire and save independent distance data from the four corner measuring points. The verification module 32 is used to verify whether the signals from both end faces are the true end faces of the roll material, filtering out false signals caused by fluffy fibers. The filtering module 33 is used to remove invalid sampling values ​​interfered with by fibers, retaining valid ones. Based on the calculated data, the calculation module 37 is used to calculate the lateral offset and offset direction of the clamping mechanism relative to the fire blanket roll. The identification module 34 is used to identify whether the roll is centered or tilted at the end. The judgment module 35 is used to automatically switch between high-speed coarse alignment and low-speed fine alignment according to the size of the deviation to prevent equipment overshoot. The compensation output module 36 is used to output displacement commands for graded speed adjustment and complete the alignment calibration in a closed loop. The working condition alarm module 38 is used to distinguish three types of faults according to fixed judgment rules and output corresponding alarm information. The specification storage module 39 is used to save multiple sets of product calibration parameters to quickly adapt to different specifications of fire blanket rolls. During the entire process of clamping and positioning, the double-sided toothed plates 222 are fed synchronously and equally. With the coordination of the induction mechanism 3 alignment and the flexible fitting of the airbag 265, the roll is always kept in the center position, effectively eliminating the problems of eccentric clamping and uneven force. This further ensures the accuracy of the fire blanket roll loading, unloading, transfer and docking processes, and improves the smoothness and stability of the overall automated conveying operation. Signal acquisition module 31: Independently acquires real-time distance data from four sets of sensing elements at the four corners, divides them into paired measurement points on the left and paired measurement points on the right, completes the digital conversion of analog signals, retains the independent original sampling values ​​of each measurement point, and provides a basic data source for authenticity verification; Verification module 32: Makes consistency judgment on the data of two measuring points on the same side; only when the difference between the two points on the same side falls within the allowable deviation range of the material is the signal of the end face on that side determined to be valid; it filters out false triggers caused by fluffy filaments or local fiber protrusions on the end face of the fireproof blanket, and eliminates the mispositioning problem caused by flexible materials. This judgment rule does not belong to the general positioning logic of rigid workpieces. Filtering module 33: Discards single-point abnormal values ​​that fail the verification and only uses valid measurement points that pass the verification to participate in subsequent calculations; avoids local fiber interference directly interfering with the overall alignment calculation results; Calculation module 37: Calculate the average distance between the effective measuring points on the left and right sides respectively, calculate the difference between the two sets of averages, and convert the lateral offset of the clamping mechanism relative to the roll material. Recognition module 34: Compare the effective detection data of two points on the same side to identify the special working condition of the roll material being tilted as a whole, and distinguish between two different spatial postures: left and right centering offset or roll material end face tilt. Judgment Module 35: Sets two judgment ranges: coarse positioning threshold and fine positioning threshold; outputs high-speed movement command when the deviation is greater than the coarse positioning threshold, and switches to low-speed micro-motion compensation when the deviation falls into the fine positioning range, adapting to the working conditions of heavy-duty gantry robot with large start-stop inertia, and preventing overshoot and overtravel. Compensation output module 36: Based on the offset direction and the current deviation level, outputs the displacement correction command corresponding to the speed level, and completes the alignment calibration step by step until the deviation meets the qualified accuracy range; Working condition alarm module 38: Differentiated output fault prompts, distinguishing three types of abnormal states: end face fiber interference failure, roll material placement tilt, and sensor signal loss. Different working conditions correspond to independent prompt information, rather than a unified alarm. Specification storage module 39: Stores the allowable deviation values ​​for verification of fire blankets of different thicknesses or roll diameters, as well as two-level positioning thresholds. When changing product specifications, preset parameters can be directly called to complete the quick adaptation.

[0028] Working principle: This embodiment provides a fireproof blanket roll material loading and unloading conveying device. When in use, the end face position of the fireproof blanket roll is first detected by the sensing mechanism 3. Then, the first adjustment component 12 and the second adjustment component 13 are started simultaneously to make lateral fine adjustment to the clamping mechanism so that the two side support columns 251 are precisely aligned with the end face of the roll. The external motor is started, which drives the gear 212 to rotate and simultaneously moves the toothed plates 222 on both sides towards each other. The toothed plates 222 drive the side frame 221 and side plate 224 to move closer together. As the limiting cylinder 241 and support column 251 gradually enter the two ends of the roll, the push plate 235 will contact the two end faces of the roll. As the gear 212 continues to drive the toothed plates 222 on both sides to move, the push plate 235 will gradually push the slide rod 233 to retract into the sliding sleeve 231. At the same time, the retraction action of the slide rod 233 synchronously drives the limiting cylinder 241 to move, so that the support rod 262, which was originally pressed by the limiting cylinder 241, gradually becomes exposed. The coil spring 264 then releases its elasticity to drive the rotator 261 to flip. The support plate 263 unfolds outward and fits against the inner wall of the roll, thus completing the fixation of the fire blanket roll. During the process of sliding rod 233 retracting into sliding sleeve 231, the air inside sliding sleeve 231 is compressed by sealing plate 232 and injected into through hole 253 in support column 251 through air inlet 252. Since through hole 253 is connected to airbag 265 through hose 266, air continuously enters airbag 265, causing it to gradually expand. Airbag 265 fits against the inner wall of roll material and evenly distributes the supporting force. At the same time, since the moving distance of toothed plates 222 on both sides is consistent, support column 251 always stays in the center position of roll material axis, ensuring that roll material does not shift during the fixing process. After use, the external motor is started in reverse. The gear 212 rotates in the opposite direction, causing the toothed plates 222 on both sides to separate synchronously. The side frame 221 and the side plate 224 then move outward. The push plate 235 disengages from the end face of the roll material. The slide rod 233 returns to its original position due to the elastic force of the spring 234. The limiting cylinder 241 first squeezes the support rod 262 through the conical groove 243, causing it to gradually slide into the mounting groove 254. Then, it squeezes the inclined groove on one side of the support plate 263, causing the support plate 263 to overcome the elastic force of the coil spring 264 and gradually retract and re-fit against the outer wall of the limiting cylinder 241. The air in the airbag 265 flows back to the sliding sleeve 231 through the hose 266 and the through hole 253. After the support plate 263 is completely retracted, the limiting cylinder 241 presses the support rod 262 again. The two ends of the roll material lose their support force, and the roll material falls down, completing the unloading step.
