Description

Technical Field

[0001] This utility model relates to the field of food testing, and in particular to a weight and metal detection device for bagged finished barbecue skewers. Background Technology

[0002] In the manufacturing process of packaged kebabs and similar foods, quality control is of paramount importance. As people's living standards improve, consumers have increasingly stringent requirements for food safety and quality, making food testing a key line of defense for ensuring product quality and protecting consumer health.

[0003] Traditional food testing methods often have many limitations. In terms of weight testing, they rely heavily on manual weighing, which is not only inefficient but also prone to human error. It is difficult to ensure that the weight of each bag of kebabs accurately meets the standard, which may result in consumers buying products that are underweight or overweight, affecting the consumer experience and also hindering companies from accurately controlling costs.

[0004] Traditional methods also face challenges in metal detection. Some simple metal detectors are susceptible to external electromagnetic interference, leading to false positives or false negatives. For example, in complex production environments, there are various electrical appliances and large machinery, whose electromagnetic signals may interfere with the normal operation of metal detectors. This can cause skewers containing tiny metal impurities to fail to be detected in time and enter the market, posing a potential safety risk to consumers. Once such a problem occurs, it will seriously damage the reputation of the enterprise.

[0005] Therefore, there is an urgent need for a food testing device that can collect weight and metal impurities to ensure that food products are qualified before entering the market. Utility Model Content

[0006] To address the issues of existing technologies where weighing and metal detection rely heavily on manual labor and separate testing, this utility model provides a weight and metal detection device for bagged finished barbecue skewers.

[0007] The present invention provides a weight and metal detection device for bagged finished barbecue skewers, which adopts the following technical solution:

[0008] A weight and metal detection device for bagged finished barbecue skewers includes a frame, a weight detection module and a metal detection module arranged in sequence, a conveyor belt assembly passing through the two modules, and a rejection mechanism configured at the output end of the weight detection module and the metal detection module; wherein the metal detection module is located at the end of the conveyor belt assembly in the outlet direction.

[0009] Furthermore, the conveyor belt assembly includes a discharge conveying section, a weighing detection section, and a metal detection section. The weighing detection section is installed inside the frame via a suspension support device. A weighing sensor is installed inside the weighing detection section and is electrically connected to the weight detection module. An electromagnetic shielding shell is provided around the metal detection section. The metal detection module is installed on the front side wall of the electromagnetic shielding shell.

[0010] Furthermore, the rejection mechanism includes a cylinder and a push plate. The cylinder is bolted to the top of the frame and the output end is connected to the push plate. The two push plates correspond to the defective product outlet positions of the weight detection module and the metal detection module, respectively. Infrared positioners are installed on the top of the two cylinders to receive defective product signals from the metal detection module and the weight detection module, locate the arrival of defective products, and start the cylinder.

[0011] Furthermore, a ring-shaped metal detection coil is installed inside the electromagnetic shielding shell; the ring-shaped metal detection coil adopts an orthogonal dual-frequency excitation design, and the operating frequency includes a high frequency band of 50kHz-100kHz and a low frequency band of 5kHz-20kHz. A temperature compensation sensor is configured inside the ring-shaped metal detection coil.

[0012] Furthermore, the output end of the metal detection module is also equipped with a marking device; a bracket is installed on the top of the frame; the marking device is installed on the top of the bracket by bolts, and is used to mark the qualified products when the weight detection module and the metal detection module determine that they are qualified.

[0013] Furthermore, a visual calibration component is also installed on the top of the frame. The visual calibration component consists of a CCD camera and a laser locator set on both sides of the conveyor belt assembly, which form a spatial geometric constraint relationship with the position of the barcode of the bagged meat skewers being tested.

[0014] Furthermore, a qualified product storage box is provided at the discharge end of the conveyor belt assembly; a defective product storage box is provided on the side of the conveyor belt assembly corresponding to the two rejection mechanisms; and several low-temperature holding units are respectively provided inside the qualified product storage box and the defective product storage box.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This utility model integrates a weight detection module, a metal detection module, a rejection mechanism, and a marking device. The bagged barbecue skewers pass through each detection stage in sequence on the conveyor belt, realizing a one-stop detection process from weight detection, metal detection, rejection of defective products, and marking of qualified products. There is no need for manual handling and operation between multiple devices, which greatly improves detection efficiency. It is especially suitable for enterprises with large-scale production and can significantly improve overall production efficiency.

[0017] The rejection mechanism uses an infrared locator to receive the defective product signal from the detection module and locate the defective product. The cylinder is automatically controlled to push the push plate to reject the defective product. The visual calibration component uses a CCD camera and a laser locator to accurately locate and identify the bagged skewers. The entire detection process is highly automated, reducing manual intervention, lowering labor costs, and also reducing detection errors caused by human factors.

[0018] In addition, the electromagnetic shielding shell of the metal detection section creates a stable electromagnetic environment for metal detection, avoiding the influence of external electromagnetic interference on the detection results; the ring metal detection coil adopts an orthogonal dual-frequency excitation design, combining high-frequency and low-frequency operating frequencies, which can comprehensively detect metal foreign objects of different sizes. At the same time, the temperature compensation sensor can compensate for the impact of ambient temperature changes on detection performance in real time, which greatly improves the accuracy and reliability of metal detection, effectively prevents products containing metal impurities from entering the market, and protects consumers' food safety.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in detail below:

[0024] This utility model discloses a weight and metal detection device for bagged finished barbecue skewers, such as... Figure 1-3As shown, a weight and metal detection device for bagged finished barbecue skewers includes a frame 1, a weight detection module 2 and a metal detection module 3 arranged sequentially, a conveyor belt assembly passing through the two modules, and a rejection mechanism configured at the output ends of the weight detection module 2 and the metal detection module 3; wherein the metal detection module 3 is located at the end of the conveyor belt assembly in the outlet direction; in this embodiment, the device is based on a modular design concept, constructing an automated detection system integrating weight detection, metal detection, and defective product rejection functions; by arranging the weight detection module 2 and the metal detection module 3 sequentially and allowing the conveyor belt assembly to pass through them, the bagged barbecue skewers can pass through these two key detection stages in sequence, achieving comprehensive quality control. Control; the metal detection module 3 is located at the end of the conveyor belt assembly in the exit direction. This layout conforms to the logical sequence of the inspection process: weight is detected first, then metal is detected, and finally, the product is determined based on the inspection results to either continue to the qualified product area or be rejected to the defective product area. This integrated design greatly improves inspection efficiency. Compared with the previous decentralized inspection methods, it reduces the time cost of manual handling and operation, and also reduces the probability of inspection errors caused by human factors. Through a reasonable module layout, it can ensure that each inspection link is closely connected, so that the entire inspection process runs smoothly and efficiently. It is suitable for online inspection scenarios in large-scale bagged barbecue production, effectively improving production efficiency and product quality stability.

[0025] like Figure 1-3 As shown, the conveyor belt assembly includes a discharge conveying section 42, a weighing and detection section 4, and a metal detection section 41. The weighing and detection section 4 is mounted inside the frame 1 via a suspension support device 21. A weighing sensor is installed inside the weighing and detection section 4 and is electrically connected to the weight detection module 2. The metal detection section 41 is circumferentially equipped with an electromagnetic shielding shell 31. The metal detection module 3 is installed on the front sidewall of the electromagnetic shielding shell 31. In this embodiment, the conveyor belt assembly is subdivided into the discharge conveying section 42, the weighing and detection section 4, and the metal detection section 41. This segmented design is to adapt to the needs of different detection stages. The weighing and detection section 4 is mounted inside the frame 1 via the suspension support device 21. Inside the frame 1, the use of a suspended support effectively reduces the impact of external vibrations on the weighing sensor, improving weighing accuracy. When bagged skewers are placed in the weighing detection section 4, the weighing sensor can accurately sense their weight and transmit the signal to the weight detection module 2 for judgment. The metal detection section 41 is equipped with an electromagnetic shielding shell 31 around its perimeter, which aims to create a stable electromagnetic environment for metal detection, avoid the influence of external electromagnetic interference on the operation of the metal detection coil, and ensure the accuracy of metal detection. Even tiny metal particles can be effectively detected, reducing the safety hazards that may be caused by metal foreign objects mixed into the product, and enhancing the safety and reliability of product quality.

[0026] like Figure 1-3As shown, the rejection mechanism includes a cylinder 5 and a pusher plate 52. The cylinder 5 is bolted to the top of the frame 1, and the output end is connected to the pusher plate 52. The two pushers 52 correspond to the defective product outlet positions of the weight detection module 2 and the metal detection module 3, respectively. Infrared locators 51 are installed on the top of both cylinders 5, which receive defective product signals from the metal detection module 3 and the weight detection module 2, respectively, and locate the arrival of defective products, and then start the cylinder 5. In this embodiment, when the weight detection module 2 or the metal detection module 3 detects a defective product, it will issue a defective product signal. The infrared locators 51 installed on the top of the two cylinders 5 receive these defective product signals on the one hand, and on the other hand, they activate the rejection mechanism. The system locates the position of defective products on the conveyor belt. When the defective product reaches the corresponding position, the cylinder 5 is activated to push the push plate 52 to remove the defective product from the conveyor belt. This rejection mechanism can quickly and accurately remove unqualified products from the production line, ensuring that qualified products continue to flow normally. Through the dual function of the infrared positioner 51, it can respond to the defective product signal sent by the detection module in a timely manner and accurately grasp the rejection time, avoiding the occurrence of accidental rejection or missed rejection. This effectively improves the accuracy and reliability of defective product rejection, reduces the risk of quality complaints and brand damage that may be caused by defective products mixed with qualified products, and also helps to maintain the continuity and stability of the entire production process.

[0027] like Figure 1-3 As shown, a ring-shaped metal detection coil 32 is installed inside the electromagnetic shielding shell 31. The ring-shaped metal detection coil 32 adopts an orthogonal dual-frequency excitation design, with operating frequencies including a high-frequency band of 50kHz-100kHz and a low-frequency band of 5kHz-20kHz. A temperature compensation sensor 33 is disposed inside the ring-shaped metal detection coil 32. In this embodiment, the ring-shaped metal detection coil 32 adopts an orthogonal dual-frequency excitation design, with operating frequencies including a high-frequency band of 50kHz-100kHz and a low-frequency band of 5kHz-20kHz. The high-frequency signal has strong penetrating power and can quickly detect larger metal foreign objects; the low-frequency signal is more sensitive to smaller metal foreign objects. The combination of the two can achieve comprehensive detection of metal foreign objects of different sizes. The temperature compensation sensor 33 is configured inside module 32 because the performance of the metal detection coil is affected by the ambient temperature. Temperature changes may alter parameters such as the coil's resistance and inductance, thus affecting the accuracy of the detection results. The temperature compensation sensor 33 can monitor ambient temperature changes in real time and make corresponding compensation adjustments, ensuring that the metal detection module 3 can work stably and accurately under different temperature conditions. The orthogonal dual-frequency excitation design broadens the range and accuracy of metal detection, greatly improving product safety. The presence of the temperature compensation sensor 33 enables the equipment to maintain stable metal detection performance in various complex production environments, reducing detection errors caused by environmental factors, further improving the reliability and consistency of detection results, and ensuring the stability of product quality.

[0028] like Figure 1-3 As shown, the output end of the metal detection module 3 is also equipped with a marking device 8; a bracket 7 is installed on the top of the frame 1; the marking device 8 is installed on the top of the bracket 7 by bolts, and is used to mark the qualified products when the weight detection module 2 and the metal detection module 3 determine that they are qualified products; in this embodiment, when both the weight detection module 2 and the metal detection module 3 determine that the product is qualified, the marking device 8 will mark the product with a qualified mark for subsequent differentiation and management; the marking device 8 provides convenience for product quality traceability and management, and consumers or production managers can quickly identify qualified products that have undergone strict testing through the qualified mark. At the same time, it is also convenient to perform statistical and sorting operations on qualified products during the production process, which is conducive to the standardized management of the production process and improves the efficiency and quality control level of the entire production operation;

[0029] like Figure 1-3 As shown, a visual calibration component 6 is also installed on the top of the frame 1. The visual calibration component 6 consists of a CCD camera 61 and a laser locator 62 set on both sides of the conveyor belt assembly, forming a spatial geometric constraint relationship with the position of the barcode of the bagged meat skewers being tested. In this embodiment, the CCD camera 61 can acquire image information of the bagged skewers, while the laser locator 62 assists in determining its precise position on the conveyor belt. Through the cooperation of the two, the barcode of the bagged skewers and its posture on the conveyor belt can be accurately identified, providing accurate spatial positioning reference for the subsequent inspection process and ensuring that the inspection results correspond one-to-one with the specific products. The application of the visual calibration component 6 improves the intelligence and accuracy of the entire inspection system. By accurately locating and identifying the bagged skewers, it avoids inspection errors or data confusion caused by factors such as non-standard product placement. For example, it can accurately correspond to the specific product during weight detection, and can also ensure that the correct product is processed during subsequent operations such as marking, thereby further improving the overall reliability and effectiveness of product quality inspection and reducing errors caused by human operation or product placement problems.

[0030] like Figure 1-3As shown, a qualified product storage box 91 is provided at the discharge end of the conveyor belt assembly; a defective product storage box 9 is provided on the side of the conveyor belt assembly corresponding to the two rejection mechanisms; several low-temperature holding units 92 are respectively provided inside the qualified product storage box 91 and the defective product storage box 9; in this embodiment, the setting of the storage boxes facilitates the centralized management and classification of products. The qualified product storage box 91 can store qualified products in an orderly manner, which is convenient for subsequent packaging, warehousing and other operations; the defective product storage box 9 facilitates the unified analysis and processing of unqualified products; the function of the low-temperature holding unit 92 is to extend the shelf life of bagged barbecue skewers during the temporary storage stage, ensure that the products can still maintain good quality during the short-term waiting for processing, reduce product loss and quality problems caused by improper temporary storage, and improve product utilization and enterprise production efficiency.

[0031] The implementation principle of this utility model embodiment is as follows:

[0032] In this invention, during testing, the bagged finished skewers are first placed at the feed end of the conveyor belt assembly, and the skewers enter different testing stages sequentially along the conveyor belt.

[0033] The bagged skewers enter the weighing and detection section 4. The weighing sensor inside the weighing and detection section 4 senses the weight of the skewers and transmits the weight signal to the weight detection module 2. The weight detection module 2 analyzes and processes the received weight signal and compares the actual weight with the preset standard weight range. If the weight is within the standard range, the skewers continue to move forward with the conveyor belt and enter the metal detection stage. If the weight is not within the standard range, the weight detection module 2 issues a defective product signal. This signal is received by the infrared positioner 51 on the top of the cylinder 5 at the defective product outlet of the corresponding weight detection module 2. The infrared positioner 51 monitors the position of the skewers in real time. When the skewers reach the designated position, the cylinder 5 is activated. The cylinder 5 pushes the push plate 52 to push the skewers that do not meet the weight requirements from the conveyor belt to the corresponding defective product temporary storage box 9.

[0034] After passing the weight test, the bagged skewers enter the metal detection section 41. When the skewers pass through the ring metal detection coil 32, if there are metal impurities in the skewers, the metal detection module 3 will detect an abnormal signal and issue a defective product signal. This signal is received by the infrared positioner 51 on the top of the cylinder 5 at the defective product outlet of the corresponding metal detection module 3. The infrared positioner 51 locates the position of the skewers. When the skewers reach the designated position, the cylinder 5 is activated. The cylinder 5 pushes the push plate 52 to push the skewers containing metal impurities from the conveyor belt to the corresponding defective product temporary storage box 9. If there are no metal impurities in the skewers, the skewers continue to move forward with the conveyor belt to the output end of the metal detection module 3.

[0035] When the bagged kebabs that have passed both weight and metal detection arrive at the output end of the metal detection module 3, the marking device 8 will mark the product with a qualified mark. The qualified kebabs that have been marked continue to be conveyed to the discharge end by the conveyor belt and finally fall into the qualified product storage box 91. Since the qualified product storage box 91 is equipped with a low temperature holding unit 92, the freshness and quality of the kebabs can be maintained.

[0036] Finally, it is necessary to periodically analyze and process the defective products in the defective temporary storage box 9 to find the cause of the defects so as to adjust and improve the production process; when the products in the qualified product temporary storage box 91 reach a certain quantity, subsequent packaging, warehousing and other operations are carried out.
