Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product sorting, in particular to a weighing and sorting device and weighing and sorting equipment. Background Art
[0002] Dynamic checkweighers play a crucial role in weight checking and data management in modern manufacturing. Specifically, through built-in high-precision sensors and advanced algorithms, dynamic checkweighers can rapidly capture product weight information as it passes through at high speeds and compare it with pre-defined weight zones. If a product exceeds or falls below the specified weight range, the system immediately triggers a rejection mechanism, automatically removing the unqualified product from the production line. This process not only enables real-time monitoring of the production process but also significantly improves production efficiency and product quality.
[0003] However, the design and operation of existing rejectors still have some shortcomings. First, many rejectors simply push rejected products onto a conveyor belt. This crude rejection method can easily lead to confusion between rejected and qualified products, especially on high-speed production lines, where this confusion can be more serious. Furthermore, rejected products may roll far away, making subsequent collection and handling more difficult and potentially posing a safety hazard to the production environment.
[0004] More seriously, the vibration and impact generated by the rejector during operation can adversely affect the dynamic checkweigher's weighing sensors, thereby interfering with its weighing accuracy. This interference can cause previously qualified products to be mistakenly judged as unqualified and rejected, not only reducing the product's first-time pass rate but also increasing the difficulty and frequency of self-checks for operators, further reducing production efficiency. Utility Model Content
[0005] In view of this, the purpose of the present invention is to overcome the deficiencies in the related art. The present invention provides a weighing and sorting device and a weighing and sorting equipment.
[0006] The utility model provides the following technical solutions:
[0007] A weighing and sorting device is provided on a weighing and sorting device. The weighing and sorting device comprises a rejecting component and a blocking component.
[0008] The rejection component is arranged on the weighing and sorting equipment, and the conveyor belt of the weighing and sorting equipment has a weighing part and a sorting part. The rejection component is located on the side of the sorting part; the rejection component is used to reject unqualified products on the sorting part from the conveyor belt; the blocking member includes a horizontal plate and a vertical plate, the horizontal plate is arranged above the sorting part, and the vertical plate is arranged on the side of the sorting part away from the rejection component, the upper end of the vertical plate is fixedly connected to the end of the horizontal plate away from the rejection component, and the blocking member is used to limit the movement trajectory of the unqualified products rejected from the conveyor belt by the rejection component.
[0009] As a further improvement of the above technical solution, the rejection component includes an air nozzle, which is arranged on the base of the weighing and sorting equipment, and the air nozzle is externally connected to an air compressor.
[0010] As a further improvement of the above technical solution, a plurality of air holes corresponding to the air nozzles are evenly distributed on the vertical plate.
[0011] As a further improvement of the above technical solution, the weighing and sorting device also includes a windshield, which is installed on the base. The corresponding cover of the windshield is arranged on the outside of the weighing part, and an open groove for transporting products by the conveyor belt is opened on the side of the windshield.
[0012] As a further improvement of the above technical solution, the blocking member and the wind shield are both made of transparent material.
[0013] As a further improvement of the above technical solution, the blocking member and the windshield are made of organic transparent plastic material and are integrally formed by heating and softening the plate-like material.
[0014] As a further improvement of the above technical solution, the position of the open groove away from the conveyor belt is the groove bottom, and the groove bottom is lower than the transverse plate in the vertical direction.
[0015] As a further improvement of the above technical solution, the jetting direction of the air nozzle is parallel to the conveying surface of the conveyor belt, and the jetting direction of the air nozzle is perpendicular to the traveling direction of the conveyor belt transporting the product.
[0016] As a further improvement of the above technical solution, the transverse plate is parallel to the conveying surface of the conveyor belt, and the end surface of the transverse plate close to the air nozzle is perpendicular to the air jet direction of the air nozzle.
[0017] As a further improvement of the above technical solution, side baffles are respectively provided on both sides of the horizontal plate and the vertical plate relative to the jetting direction of the jet nozzle.
[0018] As a further improvement of the above technical solution, a telescopic rod is provided on the horizontal plate, and the telescopic rod is vertically passed through the base. A tightening rod is passed through the base through threaded cooperation, and the tightening rod passes through the base and presses on the side wall of the telescopic rod.
[0019] The present invention further provides a weighing and sorting device, comprising any one of the weighing and sorting devices described above.
[0020] Compared with the related art, the beneficial effects of the present invention are:
[0021] During the installation phase of the weighing and sorting device provided by this utility model, technicians first install the reject assembly on the sorting section of the conveyor belt of the weighing and sorting equipment to ensure that it can respond quickly and accurately perform the rejection task in subsequent operations. Subsequently, the barrier is installed in two parts: a horizontal plate and a vertical plate. The horizontal plate is installed directly above the sorting section, while the vertical plate is installed on the side of the sorting section away from the reject assembly, forming an effective lateral barrier.
[0022] In actual use, products to be weighed are placed on the conveyor belt, either manually or using automated transport equipment. The conveyor belt then uses its steady power to transport each product to the weighing station for precise weight testing. When a product passes the weighing test and its weight meets the preset standard, the system intelligently determines it as qualified. The rejection component remains silent and does not participate in any operations, allowing qualified products to continue moving along the conveyor belt, smoothly passing through the sorting station, and ultimately converging to a designated area for centralized collection or seamlessly connecting to the next production process, ensuring continuity and efficiency in the production process.
[0023] However, if a product is deemed defective due to weight exceeding or falling below the specified range, the intelligent module within the weighing unit immediately activates an emergency response mechanism, rapidly sending a rejection command to the rejection unit. Driven by this command, the rejection unit precisely intervenes, quickly and accurately removing the defective product from the conveyor belt as it passes through the sorting section, preventing it from disrupting subsequent production processes.
[0024] Particularly noteworthy is the crucial role played by the horizontal and vertical plates of the barrier during the rejection of rejected products. They precisely restrict the movement of rejected products, ensuring they land accurately within the pre-set collection area after rejection, effectively preventing scattered, difficult-to-recover products. This design not only significantly improves the efficiency of reject recovery but also significantly reduces the risk of confusion between qualified and rejected products, providing a solid foundation for quality control on the production line.

[0036] Example 1
[0037] Combine Figure 1 、 Figure 2 As shown, this embodiment provides a weighing and sorting device, which is arranged on a weighing and sorting equipment. The weighing and sorting device includes a rejecting component 100 and a blocking component 300.
[0038] The rejection component 100 is arranged on the weighing and sorting equipment. The conveyor belt 210 of the weighing and sorting equipment has a weighing part 211 and a sorting part 212. The rejection component 100 is located on the side of the sorting part 212; the rejection component 100 is used to reject unqualified products on the sorting part 212 from the conveyor belt 210; the blocking member 300 includes a horizontal plate 310 and a vertical plate 320. The horizontal plate 310 is arranged above the sorting part 212, and the vertical plate 320 is arranged on the side of the sorting part 212 away from the rejection component 100. The upper end of the vertical plate 320 is fixedly connected to the end of the horizontal plate 310 away from the rejection component 100. The blocking member 300 is used to limit the movement trajectory of the unqualified products rejected from the conveyor belt 210 by the rejection component 100.
[0039] During the installation phase of the weighing and sorting device provided in this embodiment, technicians first install the reject assembly 100 on the sorting section 212 of the weighing and sorting equipment's conveyor belt 210 to ensure it can quickly respond and accurately perform its rejection tasks during subsequent operations. Subsequently, the barrier 300 is installed in two parts: a horizontal plate 310 and a vertical plate. The horizontal plate 310 is installed directly above the sorting section 212, while the vertical plate is installed on the side of the sorting section 212 away from the reject assembly 100, forming an effective lateral barrier.
[0040] In actual use, products to be weighed are placed on conveyor belt 210, either manually or using automated transport equipment. Conveyor belt 210 then uses its steady power to transport the products one by one to the weighing section 211 for pause and weight testing. When a product passes the weighing test and its weight meets the preset standard, the system intelligently determines it as qualified. At this point, the reject assembly 100 remains silent and does not participate in any operations, allowing qualified products to continue to move along the conveyor belt 210, smoothly passing through the sorting section 212, and ultimately converging to a designated area for centralized collection or seamlessly connecting to the next production process, ensuring a continuous and efficient production process.
[0041] However, if a product is deemed unacceptable due to weight exceeding or falling below a specified range, the intelligent module within the weighing unit 211 immediately activates an emergency response mechanism, quickly sending a rejection instruction to the rejection assembly 100. Driven by this instruction, the rejection assembly 100 quickly intervenes and removes the unacceptable product from the conveyor belt 210 as it passes through the sorting unit 212, quickly and accurately preventing the unacceptable product from interfering with the subsequent production process.
[0042] Furthermore, during the rejection process of unqualified products, the horizontal plate 310 and vertical plate of the blocking member 300 precisely restrict the unqualified products' path of movement, ensuring that they fall accurately into the pre-set collection area after being rejected, effectively preventing unqualified products from being scattered and difficult to recover. This design not only greatly improves the efficiency of unqualified product recovery, but also significantly reduces the risk of confusion between qualified and unqualified products, providing a solid guarantee for quality control on the production line.
[0043] In some specific embodiments, the rejection assembly 100 includes an air nozzle 110, which is disposed on the base 220 of the weighing and sorting equipment and is externally connected to an air compressor. When an unqualified product is detected, the system responds quickly and controls the air nozzle 110 to open. A strong and concentrated high-pressure air can be ejected from the air nozzle, acting on the unqualified product, and effectively removing it from the conveyor belt 210 by the impact force of the airflow. This non-contact rejection method avoids the physical friction that may be caused by traditional mechanical rejection, thereby maximally protecting the integrity of the conveyor belt 210 surface while rejecting unqualified products, preventing additional scratches or damage to the products themselves, and ensuring the integrity of the product appearance and quality. Of course, in other embodiments of the present invention, the rejection assembly 100 can also use structures such as telescopic push rods to reject unqualified products.
[0044] In some specific embodiments, a plurality of air holes 321 corresponding to the air nozzles 110 are evenly distributed on the vertical plate 320. When the air nozzle 110 is started and the high-pressure airflow is ejected, the presence of the air holes 321 enables the vertical plate 320 to face this force in an almost "transparent" manner. The airflow can smoothly pass through these air holes 321 and continue its path of pushing unqualified products, while the vertical plate 320 mainly plays the role of blocking and guiding these products. Such a design avoids the direct obstruction of the airflow by the vertical plate 320 as a whole, reduces the adverse phenomena such as eddies and turbulence that may be generated when the airflow passes through the vertical plate 320, thereby ensuring the effective use of the airflow energy and ensuring that unqualified products can be accurately and efficiently removed.
[0045] As a further improvement to the above technical solution, the weighing and sorting device also includes a windshield 400, which is installed on the base 220 and correspondingly covers the outside of the weighing section 211. The side of the windshield 400 is provided with an open slot 410 for the conveyor belt 210 to transport products. Specifically, the conveyor belt 210 can transport products from the weighing section 211 through the open slot 410 to the sorting section 212. When the air nozzle 110 is activated and generates a high-speed airflow to reject unqualified products, the isolation function of the windshield 400 becomes particularly important. It can effectively isolate the air flow between the weighing section 211 and the sorting section 212, preventing the high-speed airflow from directly impacting or bypassing the weighing section 211, thereby avoiding the negative impact of airflow disturbances on the product weighing results. This measure ensures that the weighing section 211 can maintain its high-precision weighing capability even during the rejection process, thereby ensuring the accuracy and reliability of sorting.
[0046] In some specific embodiments, both the blocking member 300 and the windshield 400 are made of a transparent material. The use of transparent materials ensures that operators can visually observe the product flow within the weighing unit 211 and sorting unit 212. The product weighing process, conveying trajectory, and sorting actions can all be clearly observed without opening the equipment casing or interrupting the production process. This visibility not only enhances transparency during the production process but also helps operators promptly identify and address potential issues, such as product blockages and misalignment, thereby ensuring smooth production line operation.
[0047] Furthermore, the use of transparent materials greatly facilitates equipment adjustment and maintenance. During the commissioning phase, operators can fine-tune various equipment parameters based on observed conditions to achieve optimal operating conditions. During routine maintenance, the transparent material provides a clear view of the equipment's internal structure, allowing maintenance personnel to quickly locate faults and take appropriate remedial measures. This convenience not only reduces equipment downtime, but also lowers maintenance costs and improves overall production efficiency.
[0048] In some specific embodiments, the blocking member 300 and the wind shield 400 are made of organic transparent plastic material, and are formed into one piece by heating and softening the plate-like material, which is easy to process.
[0049] In some specific embodiments, the position of the opening groove 410 away from the conveyor belt 210 is the groove bottom 411, and the groove bottom 411 is lower than the horizontal plate 310 in the vertical direction, thereby reducing the probability of unqualified products entering the weighing part 211 of the conveyor belt 210 from the opening groove 410 during the process of being blown away and rejected, thereby ensuring the normal operation of the weighing part 211.
[0050] In some specific embodiments, the jet direction of the air nozzle 110 is parallel to the conveying surface of the conveyor belt 210, so as to reduce the impact of high-speed airflow on the normal operation of the conveyor belt 210; the jet direction of the air nozzle 110 is perpendicular to the direction of transport of the product by the conveyor belt 210, so as to facilitate the rapid blowing away and removal of unqualified products.
[0051] In some specific embodiments, the transverse plate 310 is parallel to the conveying surface of the conveyor belt 210, which facilitates horizontal guidance of the moving path of unqualified products, and prevents unqualified products from flying too high when being blown away and being inconvenient to collect; the end face of the transverse plate 310 close to the air nozzle 110 is perpendicular to the air jet direction of the air nozzle 110, which facilitates the rapid interception of unqualified products that are blown away and removed from the conveyor belt 210, so that they can fall into the same position for centralized collection and processing.
[0052] In some specific embodiments, the horizontal plate 310 and the vertical plate 320 are respectively provided with side baffles 311 on both sides relative to the jet direction of the air nozzle 110, so as to guide the moving trajectory of the air nozzle 110 when it blows the product away from the position.
[0053] In some specific embodiments, a telescopic rod 312 is provided on the horizontal plate 310, and the telescopic rod 312 is vertically penetrated on the base 220. A tightening rod is penetrated on the base 220 through threaded cooperation, and the tightening rod passes through the base 220 and presses on the side wall of the telescopic rod 312, so as to facilitate the adjustment of the relative height of the blocking member 300 and the conveyor belt 210 and the air nozzle 110 as needed, so as to ensure that this embodiment is applicable to more usage scenarios.
