Description

Technical Field

[0001] This invention belongs to the field of food sampling technology, and in particular relates to a sampling device for food production processes. Background Technology

[0002] In the production and processing of food such as canned yellow peaches, in order to ensure the uniformity of product quality, it is necessary to sample and test the physicochemical indicators such as moisture and sugar content of the peach flesh after pitting and before canning. This ensures the representativeness of the samples, the standardization of the testing, and the traceability of the data. At the same time, as a fragile raw material for fruit and vegetable processing, the sampling process must avoid damaging the outer wall of the peach to prevent affecting the aesthetics of subsequent canning and the freshness of the fruit flesh.

[0003] Existing sampling devices for food production processes have many shortcomings, making it difficult to simultaneously meet the requirements of testing compliance, non-destructive sampling, and intelligent operation. Some traditional sampling equipment uses puncture and cutting methods, which can easily damage the outer wall of peach pieces and cause oxidation and spoilage of the pulp, resulting in the raw materials being unable to be processed normally after sampling and causing material waste. Moreover, the sampling process relies on manual positioning and material turning, which is inefficient, and human operation errors can easily lead to unrepresentative sample selection. In addition, some automated sampling devices lack intelligent sensing and linkage design, are only equipped with basic drive components, and lack precise positioning detection, pressure feedback adjustment, and automatic posture calibration functions, making it impossible to achieve fixed-point sampling of the pulp inside the pitted end of the peach piece, and failing to provide reliable support for precise control of food quality.

[0004] To address these issues, we propose a sampling device for food production processes. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The system utilizes a targeted sampling design on the inner side of the pitted peach piece using installation, collection, and sampling / detection components. This precise extraction of the pitted inner flesh from the peach piece ensures no damage to the outer flesh. After sampling, the peach piece can be directly returned to the production line for further processing, fundamentally avoiding any damage to the product's appearance and quality. This maximizes the preservation of the peach piece's original processing value, meeting the core requirement in food production that "sampling should not affect the quality of the finished product." Furthermore, the system achieves fully automated operation through intelligent linkage between pressure sensors, laser sensors, near-infrared sensors, and various actuators: pressure sensors provide real-time pressure signal feedback, precisely controlling the clamping force of the limit rubber disc on the peach piece to prevent material compression damage or limit failure; and the system analyzes the extension data of the electric telescopic rod corresponding to the pressure sensor. The system automatically assesses the posture of the peach pieces and completes a 180° rotation calibration without manual intervention. Near-infrared sensors quickly detect sample indicators and upload data, achieving a fully automated closed-loop process of "positioning-clamping-posture calibration-sampling-detection-reset," significantly improving sampling efficiency while avoiding human error and ensuring sampling and detection accuracy. A baffle-flipping structure isolates the sample; once the peach piece is in place, the baffle closes to prevent subsequent material from entering, ensuring that only one peach piece is sampled at a time, avoiding interference from multiple pieces. The sampling component only contacts the inner flesh of the pitted end of the peach piece, and all samples fall into the collection shell after sampling, leaving no sample residue on the surface of the execution component, effectively avoiding the risk of cross-contamination. Simultaneously, the pitting process only removes a small amount of flesh sufficient for testing, ensuring detection accuracy while avoiding material waste caused by over-sampling.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The following electrical components are all electrically connected to the external PLC controller.

[0020] Reference Figures 1-9 A sampling device for a food production process includes two mounting plates 1. Each mounting plate 1 has a mounting component 2 on its opposite sidewall. The top sidewall of each mounting plate 1 has a first groove 3. The inner wall of each first groove 3 is fixedly connected to a first electric slide rail 4.

The sidewalls of the second slide plates 23 are fixedly connected to mounting blocks 24. The top sidewalls of the mounting blocks 24 are provided with mounting screw holes 25.

[0022] Specifically, mounting plate 1 provides a stable foundation support for the entire device, precisely positioned on both sides of the conveyor to ensure balanced force distribution across the device. The second groove 21 provides a suitable installation space for the second electric slide rail 22, ensuring a reasonable layout of the drive components. The second electric slide rail 22 drives the second slide plate 23 to move smoothly, causing the mounting block 24 to adjust its position synchronously. This allows for precise alignment of the mounting screw holes 25 with the preset screw holes of conveyors of different specifications, enabling adaptation without modifying the production line, significantly reducing equipment modification costs for enterprises and improving the device's versatility. The mounting block 24, through the mounting screw holes 25 and bolts, firmly fixes the device to the conveyor, completing the overall installation and positioning. This effectively prevents the device from shaking or shifting during continuous sampling operations, ensuring the accuracy and stability of the sampling and detection actions, and meeting the needs of continuous industrial production.

[0023] In this embodiment, the collecting component 6 includes two support rods 61 fixedly connected to the top sidewalls of two first sliding plates 5. The upper ends of the two support rods 61 are fixedly connected to the same support plate 62. A third groove 63 is formed on the bottom sidewall of the support plate 62. A third electric slide rail 64 is fixedly connected to the inner wall of each third groove 63. A third sliding plate 65 is slidably connected to the bottom sidewall of the third electric slide rail 64. A first electric telescopic rod 66 is fixedly connected to the bottom sidewall of the third sliding plate 65. A collecting cylinder 67 is fixedly connected to the telescopic end of the first electric telescopic rod 66. An air pump 68 is fixedly connected to the top sidewall of the collecting cylinder 67. The air inlet of the air pump 68 extends inward through the sidewall of the collecting cylinder 67. Multiple second electric telescopic rods 69 are fixedly connected to the top inner wall of the collecting cylinder 67. The telescopic end of rod 69 is fixedly connected to the same rubber sealing ring 610. The bottom side wall of collecting cylinder 67 is fixedly connected to a fixing ring 611. The two side walls of fixing ring 611 are symmetrically fixedly connected to two guide plates 612. The side walls of guide plates 612 are each provided with a fourth groove 613. The inner wall of the fourth groove 613 is rotatably connected to a rotating rod 614. The top side wall of guide plates 612 is fixedly connected to a first motor 615. The output end of the first motor 615 passes through the side wall of the corresponding guide plate 612 and is fixedly connected to one end of the rotating rod 614. The rod wall of the rotating rod 614 is fixedly connected to a baffle 616. The side wall of one guide plate 612 is fixedly connected to a laser emitter 617, and the side wall of the other guide plate 612 is fixedly connected to a laser receiver 618.

[0024] Specifically, the support rod 61 provides stable support and fixation to the support plate 62, providing a reliable mounting carrier for the remaining components of the collection assembly 6 and ensuring the integrity of the structure; the support plate 62 is precisely installed with the third electric slide rail 64 through the third groove 63, providing a structural basis for adjusting the horizontal position of the collection cylinder 67; the third electric slide rail 64 drives the third sliding plate 65 to move smoothly, causing the collection cylinder 67 to be precisely positioned directly above the conveyor's peach block conveying path, ensuring accurate positioning of the sampling target; the first electric telescopic rod 66 drives the collection cylinder 67 to rise and fall vertically, and can precisely control the guide plate 6 The distance between guide plate 612 and the conveyor belt ensures that guide plate 612 is close to the belt without generating hard friction, thus avoiding belt wear and ensuring the corrective effect of the peach block conveying trajectory. Collection cylinder 67 provides a closed working space for negative pressure adsorption of peach blocks, and integrates components such as air pump 68 and second electric telescopic rod 69, achieving a functional integrated layout. Air pump 68 draws air from the collection cylinder 67 to create a stable negative pressure, which, combined with the sealing effect of rubber sealing ring 610, ensures the firm adsorption of peach blocks, preventing them from falling during transport. The second electric telescopic rod 69 drives the rubber sealing ring... The sealing ring 610 moves downward and fits tightly against the outer wall of the peach block, ensuring the airtightness of the negative pressure environment and improving adsorption stability; the fixing ring 611 firmly connects the collection cylinder 67 and the guide plate 612, strengthening the structural linkage and ensuring that the actions of each component are synchronized; the guide plate 612 forms a dedicated guiding channel for the peach block, accurately correcting the peach block conveying trajectory, and at the same time providing suitable installation positions for components such as the rotating rod 614 and the first motor 615, achieving unity of function and structure; the fourth groove 613 provides rotational installation space for the rotating rod 614, ensuring the flipping of the baffle 616. The operation is smooth; the first motor 615 drives the rotating rod 614 to rotate, which drives the baffle 616 to flip synchronously. After the peach block is in place, the baffle 616 closes quickly to achieve sampling isolation, blocking the entry of subsequent peach blocks and ensuring that only one peach block is sampled at a time, thus ensuring the uniqueness of the sample; the laser emitter 617 and the laser receiver 618 work together to build an intelligent detection link. When the peach block blocks the laser, a signal is triggered in real time to accurately determine that the peach block has arrived at the sampling point, providing a precise triggering basis for subsequent actions, avoiding manual positioning errors, and improving the automation and accuracy of sampling.

[0027] The operating principle of the present invention is now described as follows: First, the workers place the two mounting plates 1 on the top sidewalls of both sides of the conveyor to complete the initial positioning of the device. Then, the second electric slide rail 22 is activated, which drives the corresponding second slide plate 23 to move horizontally, thereby driving the mounting block 24 to move synchronously. When the mounting screw holes 25 on the mounting block 24 are aligned with the pre-set screw holes on the top sidewall of the conveyor, the second electric slide rail 22 is closed. The workers then pass the mounting bolts through the mounting screw holes 25 and screw them into the screw holes of the conveyor to fix the mounting block 24. This completes the installation and positioning of the entire device.

[0028] After the device is installed, the first electric slide rail 4 and the third electric slide rail 64 are activated, which respectively drive the first sliding plate 5 and the third sliding plate 65 to move, so that the collecting cylinder 67 is precisely positioned above the conveyor belt (corresponding to the peach chunk conveying path). Then, the first electric telescopic rod 66 is activated to drive the collecting cylinder 67 to move vertically downward. When the two guide plates 612 below the collecting cylinder 67 are about to contact the surface of the conveyor belt, the first electric telescopic rod 66 is closed to ensure that the guide plates 612 are close to the belt but do not generate hard friction, thus avoiding wear and tear on the belt or peach chunks.

[0029] During the normal transport of peach chunks by the conveyor, when a peach chunk passes through baffle 616, its trajectory is corrected by baffle 616, and it is transported forward along the guide channel formed by the two baffles 616 and the guide plate 612. At this time, the laser emitter 617 is activated, and the laser emitted by it is stably received by the laser receiver 618 on the corresponding side. When the peach chunk passes through the channel between the two guide plates 612, the laser is blocked by the peach chunk, and the laser receiver 618 does not receive the laser signal, thus determining that the peach chunk has completely entered the guide channel and passed the detection point. Subsequently, the two first motors 615 are activated, driving the corresponding rotating rods 614 to rotate, causing the baffles 616 to rotate synchronously until one end of the sidewalls of the two baffles 616 sticks to each other, blocking the subsequent peach chunks from entering the guide channel, ensuring that only one peach chunk is sampled at a time.

[0030] The peach chunks, having passed through guide plate 612, continue moving forward under the drive of the conveyor belt, eventually entering the fixing ring 611 below the collection cylinder 67. At this point, the second electric telescopic rod 69 is activated, pushing the rubber sealing ring 610 vertically downwards, ensuring the bottom sidewall of the rubber sealing ring 610 fits tightly against the outer wall of the semi-circular peach chunk, forming a relatively sealed space. Next, the air pump 68 is activated, continuously extracting air from the collection cylinder 67, using negative pressure suction to firmly fix the peach chunks below the collection cylinder 67. After the suction stabilizes, the first electric telescopic rod 66 is reset, raising the collection cylinder 67 and the adsorbed peach chunks to a safe operating height.

[0031] Then, the third and fourth electric telescopic rods 72 and 74 are activated, causing the U-plate 75 and connecting ring 78 to move horizontally and vertically until the connecting ring 78 is precisely aligned with the bottom of the peach block below the collection cylinder 67. Afterward, the third and fourth electric telescopic rods 72 and 74 are closed. The solenoid valve 79 at the upper end of the connecting ring 78 is opened, and the air pump 68 is simultaneously turned off. The negative pressure suction force disappears, and the peach block falls smoothly into the connecting ring 78 under the influence of gravity.

[0032] The fourth electric slide rail 711 is activated, driving multiple fourth sliding plates 712 to move, ensuring that each fifth electric telescopic rod 713 is precisely aligned with the corresponding limit position on the outer wall of the peach block. The fifth electric telescopic rod 713 is then activated, pushing the mounting cylinder 714 towards the peach block. When the limit rubber disc 718 contacts the outer wall of the peach block, it is compressed and pressure is transmitted to the detection end of the pressure sensor 715 via the mounting rod 717 and spring 716. The pressure sensor 715 converts the real-time pressure signal into an electrical signal and transmits it to the control system. When the detected value reaches a preset threshold, the system automatically controls the corresponding fifth electric telescopic rod 713 to stop moving. Once all pressure sensors 715 have returned a pass signal, all limit rubber discs 718 are tightly fitted to the outer wall of the peach block, completing the stable limit positioning of the peach block. The pressure sensor 715 feedback enables precise control of the limit force, preventing damage to the peach block or limit failure, and ensuring the stability of subsequent testing.

[0033] The control system automatically collects the extension and retraction data of multiple fifth electric telescopic rods 713 on one side of the same fourth electric slide rail 711. It then analyzes the data to determine the peach chunk's posture: if the extension distance increases from top to bottom, it indicates the pitted end of the peach chunk is facing down. In this case, the system first closes the solenoid valve 79 at the upper end of the connecting ring 78, then starts the second motor 77 to drive the round rod 76 to rotate 180°. After rotation, the motor automatically stops, ensuring the pitted end of the peach chunk faces up. The system then reopens the solenoid valve 79 at the upper end of the connecting ring 78 for subsequent sampling. If the extension distance decreases from top to bottom, it indicates the pitted end of the peach chunk is already facing up. The system determines that no posture adjustment is needed and proceeds directly to the next process. This intelligent analysis of the extension and retraction data enables automated calibration of the peach chunk's posture, providing a foundation for accurate sampling.

[0034] The sixth electric telescopic rod 719 and the seventh electric telescopic rod 721 are activated, which moves the detection plate 722 to directly above the connecting ring 78, so that the detection rod 724 and the digging block 728 are precisely close to the pitting end of the yellow peach. Then, multiple third motors 726 are activated simultaneously to drive the detection rod 724 and the connecting rod 727 to rotate, which in turn drives the digging block 728 to rotate, and a suitable amount of fruit pulp sample is dug out from the inside of the pitting end of the yellow peach. Then, the near-infrared sensor 731 is activated to quickly detect the moisture and sugar content of the dug-out fruit pulp sample. The near-infrared sensor 731 converts the detected optical signal into physicochemical index data, which is uploaded to the control system in real time and stored for archiving, so as to realize the traceability of the detection data.

[0035] After the test is completed, the control system issues a command to reset the detection plate 722 and simultaneously drives the digging block 728 to rotate in the opposite direction to reset. The dug fruit pulp sample falls into the collection shell 730 under gravity and is collected for subsequent retesting or sample retention. Then, the system controls the connecting ring 78 to move directly above the conveyor belt, and then opens the solenoid valve 79 at the lower end of the connecting ring 78. At the same time, it controls each fifth electric telescopic rod 713 to reset synchronously, releasing the limit on the yellow peach pieces. The yellow peach pieces fall smoothly into the conveyor belt and continue to move towards the canning device with the production line, completing a single sampling and testing process. Subsequent devices can operate in a cycle according to the above steps under the scheduling of the control system to achieve continuous, non-destructive, and standardized sampling and testing of yellow peach pieces during the transportation process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
