[0016] By adding a nozzle angle adjustment component and an angle sensor, the above technical solution enables adaptive adjustment of the high-temperature resistant air-blowing nozzle's spray angle. The AI control unit's pre-stored optimal spray angle parameters, combined with real-time feedback from the angle sensor, allow for precise adjustment of the blowing angle based on the sticking position and mold cavity structure of different sized tableware. This ensures the airflow directly acts on the contact interface between the tableware and the mold cavity, significantly improving the efficiency and success rate of assisted demolding. A micro servo motor drive ensures the accuracy and stability of the angle adjustment. This structure avoids the problem of fixed-angle blowing failing to adapt to different sticking situations, further reducing the scrap rate caused by sticking and increasing the yield. Simultaneously, it reduces the ineffective blowing range, lowers energy consumption, and helps reduce production costs.

Detailed Implementation
[0025] To further understand the structure, features, and other objectives of the present invention, a detailed description is provided below with reference to the accompanying drawings. The embodiments illustrated in these drawings are for illustrative purposes only and are not intended to limit the scope of the invention.
[0026] This embodiment provides an intelligent high-temperature collection, counting, and stacking device for pulp-based environmentally friendly tableware, as shown in Figure 1. It includes an in-mold state monitoring unit 1, an adsorption and transfer unit 2, an air-blowing demolding unit 3, a transfer and counting unit 4, a lifting and limiting stacking unit 5, and an AI control unit 6. This intelligent high-temperature collection, counting, and stacking device is used in the collection, counting, and stacking process during the pulp molding equipment production process. The collection, counting, and stacking process follows the high-temperature setting process. In the high-temperature setting process, the lower setting mold D and the upper setting mold are closed to complete the high-temperature setting. At the end of the high-temperature setting process, the mold is opened, the upper setting mold moves to a set position, and then the collection, counting, and stacking process is started.
[0027] Therefore, the specific installation positions of each unit in this intelligent high-temperature collection, counting, and stacking device are as follows: The in-mold status monitoring unit 1 is mounted above and to the side of the lower mold D during the shaping process, facing the tableware shaping area within the lower mold D. It is used to collect temperature data and tableware status images within the lower mold D, as well as generate tableware status information, ensuring complete collection of tableware status and temperature data within the shaping area. An adjustable-height bracket is preferred for fixing the in-mold status monitoring unit 1. The lifting and limiting stacking unit 5 is mounted on one side of the lower mold D and is used for limiting and counting tableware of different specifications. The lifting and limiting stacking unit 5 can be fixed to the ground on one side of the lower mold D with bolts. The adsorption and transfer unit 2 is mounted at the initial position above the lifting and limiting stacking unit 5 and is used to adsorb and transfer the tableware that has undergone high-temperature shaping treatment within the lower mold D to the lifting and limiting stacking unit 5. The air-blowing demolding unit 3 is installed around the adsorption and transfer unit 2 and is used to assist in demolding when tableware that has undergone high-temperature shaping treatment within the lower mold D sticks to the mold. The transfer counting unit 4 is installed behind the path of the adsorption transfer unit 2 from the shaping lower mold D to the lifting and limiting stacking unit 5. It is used to collect counting data in real time during the transfer of tableware. The detection end of the transfer counting unit 4 faces the middle area of the transfer path to ensure accurate detection of the tableware that passes by. The AI control unit 6 can be integrated into the electrical control cabinet and is mainly used to pre-store the collection, counting and stacking parameters of tableware of different specifications. In this embodiment, the tableware of different specifications includes common sizes of round lunch boxes (such as diameter: 15cm, 12cm, 25cm, etc.) and square lunch boxes (such as side length: 12cm, 15cm, 18cm, etc.). The collection, counting and stacking parameters include the movement path parameters corresponding to different specifications of tableware (such as the horizontal displacement, lifting height and movement speed from the stacking platform to the shaping lower mold, etc.), the blowing execution parameters (such as the blowing pressure and blowing time of tableware of different thicknesses, etc.), the counting threshold (such as 20 pieces per batch), the limiting execution parameters (such as the limiting distance corresponding to different sizes of tableware), and the lifting execution parameters (the height of the stacking platform that drops after each piece of tableware is stacked is equal to the height of the corresponding tableware).
[0028] In this embodiment, the in-mold state monitoring unit 1, adsorption and transfer unit 2, air blowing and demolding unit 3, transfer counting unit 4, lifting and limiting stacking unit 5, and AI control unit 6 work together in an orderly manner to ultimately achieve intelligent and automated control of the entire process of high-temperature collection, counting, and stacking of tableware inside the mold D under shaping. The specific connection relationship and coordination of each unit are shown in Figure 2.
[0029] Specifically, the in-mold status monitoring unit 1 establishes an electrical and signal connection with the AI control unit 6. When the shaping process reaches a preset node, the AI control unit 6 sends a start signal to the in-mold status monitoring unit 1. Upon receiving the start signal, the in-mold status monitoring unit 1 immediately begins to collect real-time temperature data within the shaping mold D and simultaneously captures images of the tableware's state within the shaping mold D. Subsequently, the in-mold status monitoring unit 1 analyzes and processes the collected tableware's state images to generate tableware state information. This tableware state information includes information such as tableware outline, shaping integrity, presence of mold sticking, and precise tableware position. The real-time temperature data and tableware state information are then synchronously fed back to the AI control unit 6. After receiving the data, the AI control unit 6 compares and matches the tableware state information with pre-stored collection, counting, and stacking parameters for tableware of different specifications to generate a personalized parameter combination suitable for the currently produced tableware. This includes the movement path parameters required by the adsorption transfer unit 2, the blowing execution parameters required by the blowing demolding unit 3, the counting threshold required by the transfer counting unit 4, and the limit execution parameters and lifting execution parameters required by the lifting and limiting stacking unit 5.
[0030] During the adsorption and transfer process, the adsorption and transfer unit 2 establishes electrical and signal connections with both the in-mold state monitoring unit 1 and the AI control unit 6. The AI control unit 6 first transmits the generated movement path parameters to the adsorption and transfer unit 2 for parameter preset. After the in-mold state monitoring unit 1 completes data acquisition and determines that the tableware can be transferred, it sends a movement preparation signal to the adsorption and transfer unit 2. Upon receiving the movement preparation signal, the adsorption and transfer unit 2 immediately starts from its initial position and strictly follows the preset movement path parameters to perform the adsorption and transfer action, accurately inserting into the shaping lower mold D to complete the adsorption of the tableware and smoothly removing the tableware.
[0031] To address potential sticking issues, the air-blowing demolding unit 3 establishes electrical and signal connections with both the adsorption transfer unit 2 and the AI control unit 6. The AI control unit 6 transmits the generated air-blowing execution parameters to the air-blowing demolding unit 3 in advance. When the adsorption transfer unit 2 moves into the lower mold D and contacts the tableware, if abnormal adsorption resistance is detected (or the in-mold status monitoring unit has predicted sticking), it sends an air-blowing trigger signal to the air-blowing demolding unit 3. The air-blowing demolding unit 3 then executes the air-blowing action according to the preset air-blowing execution parameters, precisely spraying airflow onto the contact interface between the tableware and the lower mold D to assist demolding and ensure that the tableware smoothly detaches from the mold.
[0032] The linkage control of the counting process is achieved through the electrical and signal connections of the transfer counting unit 4 to the adsorption transfer unit 2 and the AI control unit 6, respectively. The AI control unit 6 transmits the generated counting threshold to the transfer counting unit 4. When the adsorption transfer unit 2 leaves the shaping mold D with the adsorbed tableware and enters the preset transfer path, it sends a counting trigger signal to the transfer counting unit 4. The transfer counting unit 4 then immediately starts the counting action to accurately count the tableware that has passed through the detection area, ensuring the accuracy of the number of tableware stacked in each batch.
[0033] The coordinated control of the stacking process is achieved through the electrical and signal connections between the lifting and limiting stacking unit 5 and the transfer counting unit 4 and the AI control unit 6, respectively. The AI control unit 6 first transmits the generated limit execution parameters and lifting execution parameters to the lifting and limiting stacking unit 5. If it is for the production of new tableware specifications, after receiving the limit adjustment signal sent by the AI control unit 6, the lifting and limiting stacking unit 5 adjusts the spacing of the limit structure according to the limit execution parameters to complete the stacking preparation. In the subsequent stacking process, whenever the transfer counting unit 4 completes a set tableware count, it sends a lifting trigger signal to the lifting and limiting stacking unit 5. The lifting and limiting stacking unit 5 then precisely lowers the corresponding height according to the lifting execution parameters to ensure that the tableware is stacked neatly and stably, thus achieving automated limit stacking.
[0034] In this embodiment, the in-mold state monitoring unit 1 includes a temperature sensor 11, an industrial camera 12, an image processor 13 (such as the AVS-200 / OD from Weizhun Electronics Technology (Shenzhen) Co., Ltd.), an adjustable-focus high-temperature lens 14, a light source compensation module 15 (i.e., a ring-shaped LED light source), and an industrial controller 7. The adjustable-focus high-temperature lens 14 is mounted on the imaging end of the industrial camera 12 to ensure image clarity. The light source compensation module 15 adopts a ring structure, arranged around the periphery of the adjustable-focus high-temperature lens 14, and can accurately supplement light to adapt to the imaging requirements in high-temperature environments. The industrial camera 12 and the image processor 13 are electrically and signal connected, together forming the core image acquisition and processing unit. The industrial camera 12, image processor 13, adjustable-focus high-temperature lens 14, and light source compensation module 15 are integrated into a camera assembly. It is mounted on the side and above the shaping mold D via an adjustable-angle L-shaped bracket. As shown in Figure 1, the entire process is a horizontal operation. The in-mold status monitoring unit 1 is mounted on the front side of the upper parallel bracket, with a height higher than the shaping mold D and facing the shaping mold D. It is positioned on the side and above the shaping mold D. It can also be mounted on the rear side of the upper parallel bracket, or the in-mold status monitoring unit 1 can be installed on both the front and rear sides of the upper parallel bracket. However, it should be noted that the installation height and angle of the in-mold status monitoring unit 1 need to be preset and calibrated by the actual equipment to ensure that the detection end is accurately facing the tableware shaping area inside the shaping mold D and can completely cover the area where the tableware is located. Considering that the mold D operates in a high-temperature environment (180-220℃), in order to ensure the stable operation of each component, a high-temperature resistant protective shell is provided on the temperature sensor 11 and the camera assembly. The shell is made of 304 stainless steel and filled with heat insulation cotton, which can effectively isolate the radiant heat of the mold and keep the working temperature of the internal components below 60℃.
[0035] The intelligent operation of the in-mold status monitoring unit 1 is achieved through the linkage of the industrial controller 7, the AI control unit 6, and the adsorption and transfer unit 2, as shown in Figure 3. Specifically, when the lower mold D in the shaping process completes the shaping of the tableware and opens to the preset position (i.e., the opening distance reaches at least 80% of the maximum opening stroke of the mold), the AI control unit 6 sends a start signal to the industrial controller 7 via industrial Ethernet. The industrial controller 7 establishes electrical and signal connections with the temperature sensor 11, the industrial camera 12, the image processor 13, the adjustable-focus high-temperature lens 14, and the light source compensation module 15. When the industrial controller 7 receives the start signal, it controls the light source compensation module 15 to turn on and adjust the brightness, while simultaneously controlling the adjustable-focus high-temperature lens 14 to adjust the focus to achieve clear imaging; the industrial controller 7 also simultaneously triggers the industrial camera 12 to start shooting, acquiring images of the tableware status inside the lower mold D, and triggers the temperature sensor 11 to collect temperature data in real time.
[0036] The temperature data collected by temperature sensor 11 is directly transmitted to industrial controller 7 to ensure the timeliness of temperature parameters. The tableware status image collected by industrial camera 12 is transmitted to image processor 13, which performs a series of processes such as grayscale conversion, edge extraction, and adhesion recognition to generate tableware status information containing information such as the integrity of tableware shaping, whether there is adhesion (adhesion area, adhesion location), and the precise coordinates of tableware. This tableware status information is then transmitted to industrial controller 7 after processing. After preliminary integration of the received temperature data and tableware status information, industrial controller 7 synchronously feeds back the two types of data to AI control unit 6 via bus, providing accurate basis for subsequent parameter matching.
[0037] Furthermore, the industrial controller 7 establishes an electrical and signal connection with the adsorption-transfer unit 2. Based on the analysis results of the temperature data and the tableware status information (such as the tableware has been shaped and is ready for transfer), the industrial controller 7 sends a movement preparation signal to the adsorption-transfer unit 2, thereby precisely controlling the start-up timing of the adsorption-transfer unit 2 and avoiding damage to the tableware or a decrease in production efficiency due to transfer being too early or too late.
[0038] In this embodiment, as shown in Figures 4 and 5, the adsorption transfer unit 2 includes a vacuum suction cup assembly 21, a high-temperature resistant robotic arm 22, a drive mechanism 23, and an industrial controller 7. The drive mechanism 23 is mounted on a horizontal frame and is typically fixed with high-strength bolts. The high-temperature resistant robotic arm 22 is installed vertically to the horizontal frame. One end of the high-temperature resistant robotic arm 22 is connected to the drive mechanism 23 via a coupling, while the other end is detachably connected to the vacuum suction cup assembly 21. This allows for quick replacement of the appropriate suction cup array for different sizes of pulp tableware, such as round or square, effectively improving the equipment's adaptability to various product specifications. Through this structural arrangement, the drive mechanism 23 drives the high-temperature resistant robotic arm 22 to move the vacuum suction cup assembly 21, completing reciprocating translation and lifting movements between the shaping mold D and the lifting and limiting stacking unit 5.
[0039] To ensure the accuracy of the transfer path and the stability of the suction action, this unit is equipped with a triple-sensor positioning protection mechanism. At the initial position of the vacuum suction cup assembly 21 (directly above the lifting and limiting stacking unit 5), at the end of the slide rail of the drive mechanism 23, an origin sensor 24 is installed. This sensor uses photoelectric detection to calibrate the initial position of the vacuum suction cup assembly 21 in real time, ensuring that each transfer action starts from a unified reference point and avoiding accumulated positioning errors. The drive mechanism 23 also integrates a linear displacement sensor 25, which uses grating ruler detection technology to collect real-time horizontal displacement data of the vacuum suction cup assembly 21. Depending on the size of the tableware, the vacuum suction cup assembly 21 can accurately move to directly above the tableware within the shaping mold D. Simultaneously, the vacuum suction cup assembly 21 is equipped with a pressure sensor 26, embedded in the bottom of the suction cup mounting plate, to collect the suction pressure data after the vacuum suction cup assembly 21 contacts the tableware, preventing tableware deformation due to excessive suction pressure or tableware detachment during transfer due to insufficient pressure.
[0040] In terms of control and linkage, the AI control unit 6 and the in-mold status monitoring unit 1 are electrically and signal-connected to the industrial controller 7, respectively. The industrial controller 7 is electrically and signal-connected to the drive mechanism 23. The AI control unit 6 transmits the generated movement path parameters (including translation distance, movement speed, lifting height, etc.) to the industrial controller 7. When the industrial controller 7 receives the movement preparation signal from the in-mold status monitoring unit 1, it controls the drive mechanism 23 to start the high-temperature resistant robotic arm 22 and the vacuum suction cup assembly 21 from the initial position according to the movement path parameters, and moves them precisely along the preset path towards the shaping lower mold D.
[0041] During the transfer process, the origin sensor 24 and the linear displacement sensor 25 are electrically and signal-connected to the industrial controller 7, respectively. The industrial controller 7 acquires feedback signals from the origin sensor 24 and the linear displacement sensor 25 to control the left and right movement path of the drive mechanism 23. At the initial startup of the equipment and after each transfer, the origin sensor 24 sends an initial position calibration signal of the vacuum suction cup assembly 21 to the industrial controller 7. If the assembly fails to return to its initial position, the industrial controller 7 will immediately trigger an alarm and prohibit subsequent transfer actions to ensure safe equipment operation. The linear displacement sensor 25 synchronously transmits the real-time collected displacement data to the industrial controller 7. By comparing the preset path parameters with the actual displacement data, the industrial controller 7 dynamically adjusts the running speed and stroke of the drive mechanism 23 to ensure that the vacuum suction cup assembly 21 accurately reaches the area directly above the tableware inside the shaping mold D.
[0042] When the vacuum suction cup assembly 21 moves to a position above the tableware inside the lower mold D, the drive mechanism 23 controls the high-temperature resistant robotic arm 22 to slowly lower the suction cup assembly until it contacts the tableware surface. At this point, based on the electrical and signal connection between the pressure sensor 26 and the industrial controller 7, the pressure sensor 26 immediately starts detection, collecting adsorption pressure data in real time and transmitting it to the industrial controller 7. The industrial controller 7 controls the adsorption action of the vacuum suction cup assembly 21 according to the adsorption pressure data to achieve stable adsorption of the tableware. After adsorption stabilizes (e.g., the pressure sensor reports stable pressure for 0.3 seconds), the industrial controller 7 controls the high-temperature resistant robotic arm 22 to rise, and then the drive mechanism 23 drives the suction cup assembly and the adsorbed tableware to move along a preset path to the lifting and limiting stacking unit 5, completing one adsorption transfer cycle.
[0043] To achieve stable adsorption and precise displacement of the target workpiece, the vacuum suction cup assembly 21 in this embodiment includes multiple arrayed vacuum suction cups. To improve the accuracy and flexibility of adsorption control, each vacuum suction cup is equipped with an independent vacuum solenoid valve 211, and each vacuum solenoid valve 211 is electrically and signal-connected to the industrial controller 7. The industrial controller 7 can send independent control signals to each vacuum solenoid valve 211, which responds to the signals and executes corresponding on / off actions, thereby achieving precise control of the adsorption or release state of a single vacuum suction cup. This adapts to the adsorption needs of workpieces of different sizes and shapes, ensuring the stability of the adsorption process.
[0044] To achieve multi-dimensional displacement of the vacuum suction cup assembly 21, in this embodiment, the drive mechanism 23 serves as the displacement drive unit for the vacuum suction cup assembly 21, and consists of a linear module 231 with a slider, a rotary motor 232, and a lifting cylinder 233. As shown in Figure 5, the linear module 231 is fixed on a horizontal frame and has a slider structure that can reciprocate along the extension direction of the module. The rotary motor 232 is mounted on the slider of the linear module 23 and moves synchronously with the slider. The output end of the rotary motor 232 is connected to one end of the high-temperature resistant robotic arm 22. The lifting cylinder 233 is installed in the middle of the high-temperature resistant robotic arm 22, and the other end of the high-temperature resistant robotic arm 22 is connected to the vacuum suction cup assembly 21. The linear module 231 drives the slider and subsequent connected components to move horizontally, allowing the vacuum suction cup assembly 21 to translate left and right within the stroke range of the linear module 231. The rotary motor 232 drives the high-temperature resistant robotic arm 22 to rotate through the rotation of its output end, thereby adjusting the angle of the vacuum suction cup assembly 21. It can also be used to place defective products in other positions through rotation. The lifting cylinder 233 drives the mid-section of the high-temperature resistant robotic arm 22 to rise and fall through the extension and retraction of its piston rod, ultimately achieving the vertical lifting and lowering of the vacuum suction cup assembly 21. Through the coordinated actions of translation, rotation, and lifting, the vacuum suction cup assembly 21 can accurately reach the target working position to complete the adsorption and transfer of the workpiece.
[0045] In this embodiment, as shown in Figure 6, the air-blowing demolding unit 3 includes a high-temperature resistant air nozzle 31, an airflow pressure sensor 32, an electromagnetic control valve 33, and a pressure regulating valve assembly 34. From the perspective of air path connections, the air inlet of the pressure regulating valve assembly 34 is connected to a compressed air source via a high-pressure, high-temperature resistant air pipe, providing a stable air supply for the entire air-blowing demolding unit. The air outlet of the pressure regulating valve assembly 34 is connected to the air inlet of the electromagnetic control valve 33 via a high-pressure, high-temperature resistant air pipe, and the electromagnetic control valve 33 controls the opening and closing of the air path. The air outlet of the electromagnetic control valve 33 is connected to the air inlet of the airflow pressure sensor 32 via a high-pressure, high-temperature resistant air pipe. The airflow pressure sensor 32 is used to monitor the airflow pressure in the air path in real time. Finally, the air outlet of the airflow pressure sensor 32 is sealed to the air inlet of the high-temperature resistant air nozzle 31 via a sealing joint, ensuring the sealing and stability of the airflow transmission. The outlet of the high-temperature resistant air nozzle 31 is directed toward the contact interface between the cutlery and the mold cavity inside the lower mold D during the shaping process, ensuring that the jet airflow can directly act on the separation interface and achieve a highly efficient air-assisted demolding effect.
[0046] In terms of control logic, the airflow pressure sensor 32, the solenoid control valve 33, and the pressure regulating valve assembly 34 are electrically and signal-connected to the industrial controller 7, respectively. The industrial controller 7 is also electrically and signal-connected to the AI control unit 6. The AI control unit 6 generates air blowing execution parameters based on the specifications of the tableware. These parameters include air blowing pressure thresholds and air blowing duration thresholds. After transmitting these parameters to the industrial controller 7, the industrial controller 7 triggers the pressure regulating valve assembly 34 to pre-adjust the pressure, ensuring that the air pressure reaches the preset threshold in advance. Simultaneously, the solenoid control valve 33 switches to a standby ready state, preparing for subsequent air blowing actions. During this process, the real-time pressure data adjusted by the pressure regulating valve assembly 34 is directly transmitted to the industrial controller 7, allowing the industrial controller 7 to monitor the pressure status in real time and ensure the accuracy of pressure adjustment.
[0047] To achieve coordinated operation of air-blowing demolding and adsorption transfer, the industrial controller 7 is also electrically and signal-connected to the adsorption transfer unit 2. After the adsorption transfer unit 2 moves to the demolding position and contacts the tableware surface, it sends an air-blowing trigger signal to the industrial controller 7. Upon receiving this signal, the industrial controller 7 immediately triggers the opening of the electromagnetic control valve 33. At this time, the compressed air, after being stabilized by the pressure regulating valve group 34, flows sequentially through the electromagnetic control valve 33 and the airflow pressure sensor 32, and is finally directionally sprayed through the high-temperature resistant air-blowing nozzle 31 to the contact interface between the tableware and the mold cavity. The impact force of the airflow assists in separating the tableware from the mold cavity, achieving precise linkage between the air-blowing demolding action and the adsorption transfer action. This improves the smoothness and stability of tableware demolding, prevents deformation or damage to the tableware due to uneven force during demolding, and improves operational efficiency.
[0048] To address the varying blowing angle requirements of different sized tableware, the blowing demolding unit 3 is also equipped with a nozzle angle adjustment component 35 and an angle sensor 36 to achieve adaptive adjustment of the spray angle. As shown in Figure 7, the nozzle angle adjustment component 35 consists of a micro servo motor and a transmission gear set. The micro servo motor is fixed to the periphery of the adsorption transfer unit 2. The input end of the transmission gear set is connected to the output shaft of the micro servo motor, and the output end of the transmission gear set is connected to the rotation shaft of the high-temperature resistant blowing nozzle 31, forming a power transmission structure for angle adjustment. The angle sensor 36 is installed at the end of the rotation shaft of the high-temperature resistant blowing nozzle 31. The detection end of the angle sensor 36 is coaxially connected to the rotation shaft of the high-temperature resistant blowing nozzle 31, enabling real-time acquisition of the current spray angle of the high-temperature resistant blowing nozzle 31.
[0049] The angle adjustment of the high-temperature resistant air nozzle 31 is achieved through electrical and signal connections between the micro servo motor and the angle sensor 36, respectively, and the industrial controller 7 is also electrically and signal-connected to the AI control unit 6. The AI control unit 6 pre-stores the optimal spray angle parameters corresponding to different sizes of tableware. The industrial controller 7 receives the optimal spray angle parameters matching the currently used tableware from the AI control unit 6, and simultaneously obtains the current spray angle fed back by the angle sensor 36. Then, the industrial controller 7 compares the difference between the current spray angle and the optimal spray angle, and sends an angle adjustment signal to the micro servo motor based on the difference. This controls the micro servo motor to drive the high-temperature resistant air nozzle 31 to rotate to the optimal spray angle, ultimately achieving adaptive adjustment of the spray angle and ensuring that tableware of different sizes can obtain the best air blowing and demolding effect.
[0050] To achieve accurate counting during the tableware transfer process, ensure the coordinated operation of subsequent lifting and limiting stacking units, and guarantee the orderliness and traceability of the entire production process, in this embodiment, as shown in Figure 8, the transfer counting unit 4 includes a photoelectric sensor 41, an image acquisition module 42, a counting processor 43, and an industrial controller 7. The photoelectric sensor 41 and the image acquisition module 42 are mounted on the rear side of the transfer path of the adsorption transfer unit 2 via an adjustable bracket, facing the detection area of the transfer path. The counting processor 43 is integrated into the image acquisition module 42. The photoelectric sensor 41 is used to detect in real time whether tableware has passed through the transfer path and generate an on / off detection signal, while the image acquisition module 42 is used to acquire images of tableware passing through the transfer path.
[0051] The AI control unit 6 and the adsorption-transfer unit 2 are electrically and signal-connected to the industrial controller 7, respectively. The industrial controller 7 is electrically and signal-connected to the photoelectric sensor 41 and the image acquisition module 42, respectively. Based on this connection, the AI control unit 6 transmits the generated counting threshold to the industrial controller 7. After moving to the transfer position, the adsorption-transfer unit 2 sends a counting trigger signal to the industrial controller 7. The industrial controller 7 then sends a start command to the photoelectric sensor 41 and the image acquisition module 42 according to the counting trigger signal. The photoelectric sensor 41 is electrically and signal-connected to the counting processor 43, and the counting processor 43 is electrically and signal-connected to the image acquisition module 42. When the adsorption-transfer unit 2 moves to the detection area of the transfer path, the photoelectric sensor 41 first detects the tableware and generates an on / off detection signal, which is transmitted to the counting processor 43. After receiving the on / off detection signal, the counting processor 43 triggers the image acquisition module 42 to start the image acquisition action, acquiring images of the currently passing tableware. After the image acquisition module 42 completes image acquisition, it transmits the acquired tableware image to the counting processor 43 in real time. The counting processor 43 analyzes and identifies the received tableware image, confirms the existence of valid tableware, performs a counting accumulation operation, and generates corresponding counting data to realize the counting action. This effectively avoids miscounting and missed counting, and ensures counting accuracy.
[0052] To achieve coordinated control between the counting data and subsequent stacking actions, the counting processor 43 is electrically and signal-connected to the industrial controller 7. The counting processor 43 feeds back the generated counting data to the industrial controller 7 in real time. Upon receiving the counting data, the industrial controller 7 compares it with a counting threshold in real time. When the counting data reaches the threshold, the industrial controller 7 sends a lifting trigger signal to the lifting limit stacking unit 5, triggering the lifting limit stacking unit 5 to execute the corresponding lifting action. This provides the conditions for the accurate stacking of subsequent tableware, achieving automated coordination between transfer counting and stacking actions, and improving overall production efficiency.
[0053] To achieve precise and stable stacking of tableware after transfer, and to adapt to the stacking requirements of tableware of different sizes, ensuring seamless coordination between the stacking stage and the preceding transfer and counting stage, in this embodiment, as shown in Figures 9 and 10, the lifting and limiting stacking unit 5 includes a lifting drive component 51, a limit adjustment component 52, a stacking platform 53, and an industrial controller 7. The lifting drive component 51 is connected to the bottom of the stacking platform 53 via a transmission connection, and can output stable power to drive the stacking platform 53 to rise and fall vertically, thereby adjusting the platform's bearing height to match different stacking layer requirements. The limit adjustment component 52 adopts a symmetrical layout, installed in pairs on both sides of the stacking platform 53, and can adjust the limit range according to the diameter, size, and other specifications of the tableware to accommodate tableware of different sizes, while also preventing tableware from shifting or tipping over during stacking. The stacking platform 53 provides a flat bearing surface for the tableware, and its coordinated action with the lifting drive component and the limit adjustment component constitutes the basic guarantee for stable stacking.
[0054] The lifting and limiting stacking unit 5 establishes a signal interaction system with the AI control unit 6 and the transfer counting unit 4 through the industrial controller 7, ensuring the intelligence and coordination of the stacking action. Specifically, the AI control unit 6 and the transfer counting unit 4 are electrically and signal-connected to the industrial controller 7, respectively. The AI control unit 6 transmits the generated limit execution parameters (including the target distance between the limit components on both sides, buffer stroke, etc.) and lifting execution parameters (including the initial height, single lifting stroke, and height threshold corresponding to the number of stacking layers, etc.) to the industrial controller 7. When the count reaches the counting threshold, the transfer counting unit 4 sends a lifting trigger signal to the industrial controller 7, informing that the current batch of tableware has met the stacking quantity requirements and triggering subsequent stacking adjustment actions.
[0055] To accommodate the stacking needs of different tableware sizes, the industrial controller 7 is electrically and signal-connected to the lifting drive component 51 and the limit adjustment component 52, respectively, enabling precise control of limit and height adjustments. In the limit adjustment phase, upon receiving the limit execution parameters, the industrial controller 7 synchronously responds with the limit adjustment signal and sends a control command to the limit adjustment component 52 based on the target spacing in the parameters. This drives the limit adjustment component to complete the spacing adjustment, forming a limit space that perfectly matches the current tableware size, achieving targeted limit protection for different tableware sizes and ensuring the stability of the stacking process. In the adaptive stacking height adjustment phase, upon receiving the lifting trigger signal from the transfer counting unit 4, the industrial controller 7 controls the lifting drive component 51 to move the stacking platform 53 to the appropriate height according to the lifting execution parameters. This adjustment mechanism ensures that each time new tableware is stacked, it smoothly falls to the preset position, avoiding problems such as tableware collisions and stacking misalignment caused by improper platform height, effectively improving stacking quality.
[0056] To further improve the accuracy of the limit adjustment and the protection effect of the tableware, the limit adjustment component 52 includes an electric push rod 521 and a limit plate 522. The electric push rod 521 is fixed to the side of the stacking platform 53, and the output end of the electric push rod 521 is connected to the limit plate 522. The extension and retraction of the electric push rod 521 can directly drive the limit plate 522 to move horizontally, thereby achieving precise adjustment of the distance between the two limit plates. At the same time, a flexible buffer pad is provided on the inner side of the limit plate 522. This buffer pad can play a buffering and shock-absorbing role when the tableware comes into contact with the limit plate, avoiding hard contact that could cause scratches or damage to the surface of the tableware, and ensuring the integrity of the tableware's appearance. The electric push rod 521 is electrically and signal connected to the industrial controller 7. The industrial controller 7 controls the extension and retraction of the electric push rod 521 according to the lifting execution parameters to adjust the distance between the two limit plates 522 on both sides of the stacking platform 53. By controlling the extension and retraction of the electric push rod, the distance between the two limit plates 522 on both sides is precisely adjusted to ensure that the limiting effect is perfectly adapted to the tableware specifications.
[0057] In this embodiment, the AI control unit 6 serves as the intelligent decision-making core of the entire device. It is configured to include a data storage module, a signal acquisition module, a signal processing module, a drive output module, and a human-machine interaction module. These modules are interconnected via an industrial Ethernet network and an internal bus, forming a complete AI control unit architecture. All modules utilize existing mature industrial control products, ensuring good compatibility and interchangeability. This reduces the device's R&D difficulty and production costs while guaranteeing long-term stable operation in industrial settings.
[0058] The data storage module uses industrial-grade solid-state drives (such as Advantech SQF-S25V4 series). Its core function is the storage and management of various parameters and data, specifically including: First, pre-storing a complete set of collection, counting, and stacking parameters corresponding to different specifications of pulp-based environmentally friendly tableware, covering the movement path parameters of the adsorption and transfer unit 2, the blowing execution parameters (including pressure, duration, etc.) of the blowing and demolding unit 3, the counting threshold of the transfer counting unit 4, the limit execution parameters (including target distance between the limit components on both sides, buffer stroke, etc.) and the lifting execution parameters (including initial height, single lifting stroke, stacking layer height threshold, etc.) of the lifting and limiting stacking unit 5, and pre-storing the optimal spray angle parameters corresponding to different specifications of tableware; Second, storing real-time data during the operation of the device, including the action status data of each unit, sensor feedback data (temperature, pressure, displacement, angle, etc.), and the processing quantity and quality traceability data of each batch of tableware; Third, storing fault diagnosis-related data, including common fault codes, fault triggering conditions, and emergency handling strategies, providing data support for equipment maintenance. In addition, this module supports receiving parameter update data through an external communication interface, which can flexibly adapt to the operational needs of adding new specifications of tableware and improve the versatility of the device.
[0059] The signal acquisition module uses a high-precision analog input / output module (such as the Siemens S7-1200 series) to build the signal transmission link between the AI control unit 6 and various functional units and the industrial controller 7, realizing bidirectional signal interaction: On the one hand, it receives status signals and detection data fed back by each unit through the industrial controller 7, specifically including the temperature data inside the mold D collected by the in-mold status monitoring unit 1 and the generated tableware status information, the origin positioning signal and movement displacement data of the adsorption transfer unit 2, the air pressure data and the current spray angle data of the nozzle of the blowing demolding unit 3, the real-time counting data of the transfer counting unit 4, and the limit adjustment positioning signal and platform lifting status data of the lifting limit stacking unit 5, etc.; On the other hand, it receives manual operation signals (such as start, stop, parameter modification commands, etc.) issued by the human-machine interaction module, providing data input for subsequent parameter processing and command generation.
[0060] The parameter matching and processing module uses a high-performance industrial controller (such as Omron CJ2H-CPU66 / 67-EIP) to achieve three core functions: First, parameter matching and generation: after receiving the tableware status information transmitted by the signal acquisition module, it compares and matches it with the pre-stored collection, counting, and stacking parameters of tableware of different specifications in the data storage module to accurately generate the movement path parameters, air blowing execution parameters, counting threshold, limit execution parameters, and lifting execution parameters suitable for the tableware to be processed. Second, operation status diagnosis: it compares the real-time data fed back by each sensor with the preset threshold to determine whether the operation status of each unit is normal. If abnormal parameters are detected (such as excessive temperature, insufficient pressure, execution unit not in place, excessive angle deviation, etc.), a fault alarm signal is immediately generated and an emergency handling strategy is matched. Third, action sequence coordination: according to the device operation process, it accurately plans the action sequence of each unit, clarifies the triggering conditions and connection order of actions such as in-mold detection, adsorption transfer, air blowing demolding, counting, and stacking, avoids action conflicts, and ensures a smooth and efficient operation process.
[0061] The instruction output module uses a high-reliability digital output module (such as the Schneider TM3 series) to convert the control instructions generated by the parameter matching and processing module into executable electrical signals, which are then precisely sent to the corresponding units via the industrial controller 7: First, a start signal is sent to the in-mold status monitoring unit 1 to trigger temperature acquisition and tableware status image acquisition; second, movement path parameters are sent to the adsorption and transfer unit 2 to guide it in completing the adsorption and transfer action; third, air blowing execution parameters and angle adjustment parameters are sent to the air blowing and demolding unit 3 to control the air blowing action and the adaptive adjustment of the nozzle angle; fourth, a counting threshold is sent to the transfer counting unit 4 to trigger the counting action; fifth, limit execution parameters and lifting execution parameters are sent to the lifting limit stacking unit 5 to control the limit adjustment and platform lifting action; sixth, fault alarm signals are simultaneously sent to the human-machine interaction module to trigger alarm prompts.
[0062] The human-machine interface module consists of an industrial touchscreen, physical operation buttons (start, stop, emergency stop), and indicator lights. It enables operators to interact with the device, specifically including: 1) parameter management, allowing operators to input collection, counting, and stacking parameters for new tableware specifications, modify preset parameter thresholds (such as counting threshold, pressure threshold, temperature threshold, etc.), and view historical parameter data and work records; 2) status monitoring, displaying the device's current operating mode (standby / running / fault), the action status of each unit, the currently processed tableware specifications, real-time counting data, and fault information (including fault location and cause); 3) operation control, supporting operators to manually issue start and stop commands. In emergencies, the emergency stop button can cut off the power to all execution units to ensure the safety of the equipment and personnel. It also supports single-unit action control in the equipment debugging mode, facilitating maintenance and calibration.
[0063] In this embodiment, the intelligent high-temperature collection, counting, and stacking device for environmentally friendly pulp tableware operates as follows: First, the operator starts the entire device through the human-machine interface module of the AI control unit 6. The AI control unit 6 sends initialization signals to the in-mold status monitoring unit 1, the adsorption and transfer unit 2, the air blowing demolding unit 3, the transfer counting unit 4, and the lifting and limiting stacking unit 5. Each unit, without faults, feeds back a ready status signal to the AI control unit 6. Then, the operation cycle begins.
[0064] First, after the shaping process is completed and the lower mold D is opened to the set position, the AI control unit 6 sends a start signal to the industrial controller 7. The industrial controller 7 then triggers the in-mold status monitoring unit 1 to start working: the control light source compensation module 15 is turned on and the brightness is adjusted, the adjustable focus high-temperature lens 14 is adjusted to a clear imaging state, and the industrial camera 12 is triggered to collect the status image of the tableware inside the lower mold D, and the temperature sensor 11 collects the temperature data inside the lower mold D in real time. The temperature data collected by the temperature sensor 11 is directly transmitted to the industrial controller 7, and the tableware status image collected by the industrial camera 12 is transmitted to the image processor 13 for processing to generate tableware status information. This tableware status information is also transmitted to the industrial controller 7, and the industrial controller 7 feeds back the temperature data and tableware status information to the AI control unit 6.
[0065] Then, the AI control unit 6 compares and matches the received tableware status information with the pre-stored collection, counting, and stacking parameters of tableware of different specifications in the data storage module, automatically generating movement path parameters, air blowing execution parameters, counting threshold, limit execution parameters, and lifting execution parameters adapted to the current tableware, and transmits each parameter to the corresponding industrial controller 7. After determining that the transfer conditions are met based on the received temperature data and tableware status information, the industrial controller 7 sends a movement preparation signal to the adsorption transfer unit 2.
[0066] Next, the adsorption transfer unit 2 starts from the initial position above the lifting and limiting stacking unit 5 according to the movement path parameters, moves to directly above the tableware in the lower mold D, and descends to the adsorption height. After the vacuum suction cup assembly 21 contacts the tableware, the pressure sensor 26 on it collects the adsorption pressure data in real time and transmits it to the industrial controller 7. The industrial controller 7 controls the vacuum solenoid valves 211 of each vacuum suction cup to open according to the adsorption pressure data, thus completing the adsorption and fixation of the tableware. If the tableware sticks to the mold, the adsorption transfer unit 2 sends a blowing trigger signal to the industrial controller 7. The industrial controller 7 triggers the opening of the solenoid control valve 33 of the blowing demolding unit 3. At the same time, according to the optimal spray angle parameters issued by the AI control unit 6 and the current angle fed back by the angle sensor 36, the micro servo motor drives the high-temperature resistant blowing nozzle 31 to rotate to the optimal angle. The compressed air is stabilized by the pressure regulating valve group 34 and then sprayed through the high-temperature resistant blowing nozzle 31 to the contact interface between the tableware and the mold cavity to achieve assisted demolding.
[0067] Subsequently, the adsorption and transfer unit 2, carrying the adsorbed and fixed tableware, rises and moves along a preset moving path towards the lifting and limiting stacking unit 5 under the drive mechanism 23. During this process, the linear displacement sensor 25 on the drive mechanism 23 collects the moving displacement data in real time, the origin sensor 24 assists in positioning, and the industrial controller 7 precisely controls the moving path based on this data. When the adsorption and transfer unit 2 moves to the transfer position, it sends a counting trigger signal to the industrial controller 7, and the industrial controller 7 sends a start command to the photoelectric sensor 41 and the image acquisition module 42 of the transfer counting unit 4.
[0068] When the adsorption transfer unit 2 carries the tableware to the detection area of the transfer path, the photoelectric sensor 41 first detects the tableware and generates an on / off detection signal, which is transmitted to the counting processor 43. After receiving the signal, the counting processor 43 triggers the image acquisition module 42 to acquire the tableware image. The image acquisition module 42 transmits the acquired tableware image to the counting processor 43. The counting processor 43 performs counting accumulation based on the tableware image and generates counting data, which is fed back to the AI control unit 6 via the industrial controller 7.
[0069] Afterwards, the adsorption and transfer unit 2 moves to directly above the stacking platform 53 of the lifting and limiting stacking unit 5, descends to the preset stacking height, releases the tableware, and completes the stacking and placement of the tableware. Then, the adsorption and transfer unit 2 returns to its initial position and waits for the next work cycle.
[0070] Throughout the entire operation cycle, the lifting and limiting stacking unit 5 has completed the limit adjustment according to the limit execution parameters issued by the AI control unit 6: After receiving the limit execution parameters, the industrial controller 7 synchronously responds to the limit adjustment signal, controls the extension and retraction of the electric push rod 521 of the limit adjustment component 52, and adjusts the distance between the two limit plates 522 to the target value that is suitable for the current tableware specifications; when the counting data of the transfer counting unit 4 reaches the counting threshold, the industrial controller 7 sends a lifting trigger signal to the lifting and limiting stacking unit 5, and the industrial controller 7 controls the lifting drive component 51 to drive the stacking platform 53 to move to the appropriate height according to the lifting execution parameters, so as to provide accurate positioning for the subsequent stacking and placement of tableware.
[0071] Throughout the process, the AI control unit 6 monitors the operating status of each unit in real time. If abnormal parameters are detected (such as excessive temperature, insufficient pressure, execution unit not in place, excessive angle deviation, etc.), a fault alarm signal is immediately generated. The industrial controller 7 triggers the corresponding unit to stop its operation and displays the fault information through the human-machine interaction module, ensuring safe and stable operation.
[0072] The device described in this application can produce precise, controllable, highly adaptable, efficient and stable technical effects through the coordinated operation of its various units. The specific technical effects and verification descriptions are as follows.

Precise In-Mold Status Perception, Laying a Reliable Foundation for Operation: The in-mold status monitoring unit 1, through the collaborative action of temperature sensor 11 and industrial camera 12, can accurately collect temperature data and tableware status images within the mold D during shaping. The processed tableware status information accurately reflects key states such as the integrity of the shaping and the placement position of the tableware, providing reliable data support for subsequent parameter matching and action control of each unit in the AI control unit 6. This effectively avoids problems such as transfer failure and stacking misalignment caused by unclear tableware status. Actual verification shows that the unit's accuracy in recognizing the shaping status of tableware can reach over 99%, with temperature acquisition error controlled within ±2℃, fully meeting the precise perception requirements in high-temperature environments.
[0074] 2. Targeted solution to mold sticking problem, improving yield: The air-blowing demolding unit 3 addresses the industry pain point of tableware easily sticking to the mold after high-temperature setting. Through precise control of air blowing parameters and adaptive angle adjustment, it can provide directional air blowing to assist demolding of the sticking areas during the adsorption and transfer process, effectively reducing the generation of waste products such as tableware breakage and deformation caused by mold sticking. Mass production verification shows that after adopting this device, the scrap rate caused by mold sticking problem has decreased from 18% to below 3%, and the yield has increased by more than 15%, significantly improving production efficiency.
[0075] 3. Strong adaptive processing capability, adaptable to multi-specification production: The AI control unit 6 can automatically generate various execution parameters adapted to different specifications of tableware by comparing and matching pre-stored parameters with real-time collected data. This eliminates the need for frequent manual adjustments by operators, significantly improving the device's adaptability to environmentally friendly pulp tableware of different diameters and shapes. In practical applications, the device can quickly switch to adapt to multiple tableware specifications within the diameter range of 50-200mm, with a parameter switching response time of ≤0.5s, meeting the needs of flexible production.
[0076] 4. Fully automated operation, increasing capacity and reducing costs: The device achieves fully automated operation from in-mold status detection, tableware adsorption and transfer, mold-assisted demolding, to transfer counting and precise stacking, without requiring manual intervention in any step. Production data verification shows that compared with traditional semi-automated equipment, this device reduces the single tableware processing cycle from 8 seconds to less than 5 seconds, increasing capacity by more than 10%; at the same time, it reduces labor costs associated with manual operation, and combined with a reduction in scrap rate, the overall production cost is reduced by more than 10%.
