Description

Technical Field

[0001] This utility model relates to the technical field of slipper production equipment, specifically to a device for automatically adjusting the direction of slippers during the conveying process after slipper production and detecting the sole pattern, which is a high-efficiency conveying and detection system that can effectively improve the automation level of slipper production and the efficiency of product quality detection. Background Technology

[0002] In the post-production processing of slippers, conveying and quality inspection are crucial steps. Currently, most slipper manufacturers face the following problems during the conveying process: traditional conveying equipment only has simple transport functions and cannot automatically adjust the direction of the slippers, resulting in slippers being placed haphazardly on the conveyor belt. To ensure that the slippers enter the subsequent assembly or packaging stations in a uniform direction, companies often need to manually adjust the placement of the slippers, which not only increases labor costs but is also inefficient and cannot meet the needs of large-scale industrial production. Furthermore, the accuracy and consistency of manual operation are difficult to guarantee, and improper slipper orientation can easily affect the production efficiency and product quality of subsequent processes.

[0003] Furthermore, existing technologies for inspecting shoe sole patterns have significant shortcomings. Many companies still rely on manual visual inspection, depending on workers' experience and visual observation to determine the quality of the sole pattern. This method is highly susceptible to human error, has low accuracy, and struggles to detect subtle defects such as blurred patterns, missing material, or broken patterns. In addition, manual inspection cannot accurately assess the direction and integrity of the sole's friction pattern, leading to the entry of potentially substandard slippers into the market, damaging the company's brand image and consumer experience. While some machine vision inspection devices exist, they are structurally complex and costly, and most can only inspect sole patterns individually, failing to integrate effectively with the slipper conveying process and lacking a unified solution. Therefore, there is an urgent need to design a device that can automatically adjust the slipper conveying direction and perform efficient and accurate sole pattern inspection to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency conveying and detection system. Through innovative structural design, it can automatically adjust the conveying direction of slippers and accurately detect the sole pattern, thereby improving production efficiency, reducing labor costs, and ensuring product quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The high-efficiency conveying and detection system of this utility model includes a conveying unit, a direction adjustment unit, a shoe sole pattern detection unit, and a control unit.

[0007] The conveying unit adopts a double-row chain conveyor belt structure, with two rows of conveyor belts arranged in parallel and running synchronously for conveying slippers in pairs. Each row of conveyor belts has anti-slip protrusions on its surface to prevent slippers from sliding during conveying and to ensure the stability of the conveying process.

[0008] The orientation adjustment unit is located in the middle of the conveyor unit and includes vision recognition modules mounted on both sides of the conveyor belt and a rotation adjustment mechanism positioned above the conveyor belt. The vision recognition modules employ a combination of an image capture unit and a light source. The image capture unit captures real-time images of the top of the slippers on the conveyor belt and uses an image recognition algorithm to determine the slippers' orientation. When a slipper's orientation is detected to be inconsistent with a preset orientation, the control unit issues a command, activating the rotation adjustment mechanism. The rotation adjustment mechanism includes a rotatable support plate and a rotary motor that drives the support plate to rotate. The support plate 23 achieves multi-directional following rotation through the combination of the universal joint 26 and the rotary linkage of the rotary motor 24. The four corners of the support plate are connected to independent lifting and adjusting air rods. The support plate is placed between the conveyor belts and its surface is in contact with the bottom of the slipper. The rotary motor drives the support plate to rotate, thereby adjusting the slipper to the correct direction. The independent lifting and adjusting air rods adjust the height according to the direction of rotation. The support plate 23 achieves multi-directional following free angle rotation and tilting through the combination of the universal joint 26 and the rotary linkage of the rotary motor 24, so that the slipper slides stably from the support plate onto the subsequent conveyor belt.

[0009] The sole pattern detection unit, located at the end of the conveyor unit, includes a bottom vision inspection component and a defect recognition system. The bottom vision inspection component comprises a high-resolution line scan camera and a strip backlight positioned below the conveyor belt. The high-resolution line scan camera has a resolution of at least 2048 pixels. The camera captures images of the slipper's bottom from above, while the strip backlight provides uniform illumination to highlight the details of the sole pattern. The captured images are transmitted to the defect recognition system, which has a built-in preset sole pattern standard template. Through image comparison and analysis, the system can detect defects such as the integrity of the sole pattern and the consistency of the friction pattern's direction.

[0010] The control unit employs a programmable logic controller (PLC), which is electrically connected to the conveyor unit, the orientation adjustment unit, and the sole pattern detection unit. The PLC receives signals from the vision recognition module and the bottom vision detection component, and controls the rotation adjustment mechanism, the conveyor belt operation, and the processing of detection results according to a preset program. When a defective product is detected, the control unit controls a rejection mechanism located on one side of the conveyor belt to remove the defective slippers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features automated direction adjustment. Through a visual recognition module and a rotation adjustment mechanism, it achieves automatic detection and adjustment of the slipper conveying direction, replacing manual adjustment, greatly improving production efficiency and reducing labor costs.

[0013] This invention provides precise inspection quality. Utilizing a high-resolution line scan camera and advanced image recognition algorithms, it can comprehensively and accurately inspect the texture of shoe soles, effectively identifying subtle texture defects and ensuring that product quality meets standards.

[0014] This utility model adopts an integrated design, integrating slipper conveying, direction adjustment and sole pattern detection functions into the same device. The units cooperate with each other to form a complete automated system, reducing the equipment footprint and improving the continuity of the production process.

[0015] This utility model has a simple structure, low cost, and wide applicability. Compared with existing complex machine vision inspection equipment, the structure of this utility model is simpler, and the components used are all common industrial components, which reduces the manufacturing cost of the equipment and makes it suitable for promotion and application by small and medium-sized enterprises.

[0036] Preferably, the control unit 4 is also connected to a display screen 41, which is used to display the detection results and the operating status of the equipment.

[0037] First embodiment:

[0038] This invention relates to a conveying and sole pattern detection device. The double-row chain conveyor belt 11 of the conveying unit 1 operates at a stable speed. Anti-slip protrusions 12 on the surface of each conveyor belt 11 effectively prevent cotton slippers from sliding during transport. When the slippers are conveyed to the direction adjustment unit 2, the image capture units of the visual recognition modules 21 on both sides capture real-time images of the top of the slippers. During the conveying process, the limiting baffles 13 on both sides of the conveyor belt 11 help limit the movement of the slippers, preventing them from falling off or shifting from the conveyor belt 11. During production, if the image capture unit detects that some slippers are facing the wrong direction, the control unit 4 immediately issues a command, starting the rotary motor 24 of the rotary adjustment mechanism 22, which rotates the support plate 23, quickly adjusting these incorrectly oriented slippers to a uniform direction. The entire adjustment process is rapid and accurate. An independent lifting and adjusting air rod 25 adjusts the slippers according to the rotation direction, causing them to slide from the support plate 23 onto the subsequent conveyor belt 11. The average adjustment time for each pair of slippers is no more than 1 second.

[0039] After orientation adjustment, the slippers continue to be conveyed to the sole pattern detection unit 3. The high-resolution line scan camera 32 and the strip backlight 33 of the bottom vision detection component 31 work together to clearly capture images of the slipper sole's pattern and transmit them to the defect identification system. The system successfully detects slippers with blurred patterns and localized material shortages by comparing them with a preset standard template. The control unit 4 then controls the rejection mechanism 5 to remove these defective slippers from the conveyor belt 11, ensuring that only qualified products enter the subsequent packaging stage. Operators can intuitively monitor the equipment's operating status and processing results by operating the control unit 4 and viewing the display screen 41. Using this device significantly improves production efficiency, reduces labor costs, and effectively guarantees product quality.

[0040] Second embodiment:

[0041] When processing other batches of products, especially those with complex sole patterns requiring higher precision, the device does not require large-scale modifications to the conveying and inspection equipment. During conveying and orientation adjustments, the device operates stably, accurately aligning the rubber slippers to a uniform direction. In the sole pattern inspection stage, the high-resolution line scan camera 32, with its high-definition and accurate imaging capabilities, clearly captures the intricate details of the rubber slippers' sole patterns. The defect identification system, through an optimized image comparison algorithm, rigorously inspects the consistency of the sole friction pattern's direction and the integrity of the pattern. During inspection, if rubber slippers are identified as having incorrect sole friction pattern orientation or broken patterns, the pneumatic pusher 51 of the rejection mechanism 5 removes the problematic products to the waste collection bin 52 for subsequent recycling. This device maintains high efficiency and accurate inspection capabilities during the production of new rubber anti-slip slippers, meeting the diverse production needs of enterprises and providing a reliable guarantee for the production of high-quality slipper products.
