[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] like Figure 1-2 As shown, the present application relates to a tobacco seedling foam tray feeding machine and a control method thereof. Figure 1 As shown, the tobacco seedling foam tray supply machine includes: a frame 10; it is the basic frame and supporting structure of the entire equipment, and at the same time, provides an installation basis for all other components, ensuring that the equipment is firmly placed on the working plane and withstands various forces and vibrations during operation; it can provide structural stability, rigidity and installation point effects.

[0023] A carrying platform 20 is horizontally arranged on the top of the frame 10; it serves as a direct installation base for the conveying mechanism 30 and provides a horizontal reference surface to ensure the smooth operation of the conveyor belt or other conveying devices.

[0024] A conveyor mechanism 30 is disposed horizontally on the support platform 20. This horizontal conveying device, typically a belt conveyor, roller conveyor, or chain conveyor, is installed on the support platform 20 and is responsible for conveying individual foam trays horizontally. It transports the foam trays separated by the tray separation mechanism 50 and delivers them in the feed direction (typically away from the stacking bin) to the next workstation.

[0025] A shell 40 is vertically arranged on the top of the frame 10 and located at the end of the feeding direction of the conveying mechanism 30; it can achieve a good protection effect.

[0026] The tray separation mechanism 50 is provided on one side of the shell 40 ; it is a core component capable of realizing automatic tray separation, which separates a foam tray stacked at the bottom from the stack above and releases or pushes it to the conveying mechanism 30 below.

[0027] The width adjustment mechanism 60 is provided on both sides of the frame 10 and is provided on the same side as the tray separation mechanism 50 ; it can achieve a good width adjustment effect, thereby being able to adapt to products of various specifications.

[0028] The tray separation mechanism 50 and the width adjustment mechanism 60 together form a semi-open foam tray stacking bin along the feeding direction. Foam trays are sequentially fed through the conveying mechanism 30 and the tray separation mechanism 50 for automatic tray feeding and separation. This fully automates the process of separating individual foam trays from a stack and delivering them, replacing manual operations, significantly improving production efficiency and reducing labor costs and errors.

[0029] From the above description, it can be seen that this application achieves the following technical effects: In the embodiment of the present application, an automatic tray supply and tray separation method is adopted, and a semi-open foam tray stacking bin is formed along the feeding direction by the tray separation mechanism 50 and the width adjustment mechanism 60, and the foam trays are passed through the tray separation mechanism 50 in sequence to automatically supply and separate the trays, thereby achieving the purpose of automated tray supply operation, thereby realizing the technical effects of improving production efficiency, reducing labor intensity and stabilizing production, and further solving the technical problems that the existing foam tray transportation and tray loading are mainly manual operations with low efficiency and high labor intensity, and there are problems such as stacked foam trays slipping, deformation and inaccurate docking, which seriously affect the stability and continuity of the automated seedling line.

[0030] Furthermore, the frame 10 is also provided with a visual recognition module, and is located above the foam tray stacking bin, for identifying the presence, posture, and boundary alignment status of the foam tray. It can be understood that the detection of the presence of the foam tray: prevents empty bin operation; Posture / boundary alignment: Identify disc tilt and offset (e.g. >5° tilt or edge beyond the guide plate); Real-time feedback: transmit image data to the control module (resolution ≥1280×1024, frame rate 30fps).

[0031] Furthermore, the frame 10 is further provided with a control module, which is electrically connected to the conveying mechanism 30, the tray separation mechanism 50, the width adjustment mechanism 60 and the visual recognition module respectively; The control module sends control signals based on the detection signals detected and fed back by the visual recognition module to control the operations of the conveying mechanism 30, the tray separation mechanism 50 and the width adjustment mechanism 60. It can be understood that precise automatic control effects can be achieved.

[0032] Furthermore, the disc separation mechanism 50 includes a lifting assembly connected to one side of the housing 40, and a limit portion is provided at the output end of the lifting assembly. It can be understood that a good disc separation effect can be achieved.

[0033] Furthermore, the width adjustment mechanism 60 includes a driving component connected to the frame 10 at one end, and a limit plate is provided at the output end of the driving component facing the conveying mechanism 30. It can be understood that a good driving effect can be achieved.

[0034] Furthermore, a safety protection module is provided on the frame 10, and the safety protection module includes: a safety cover provided on the frame 10, an infrared protection component and an emergency stop switch. It can be understood that the safety protection effect can be ensured.

[0035] Furthermore, a height adjustment component for adjusting the levelness of the rack 10 is provided at the bottom of the rack 10. It is understandable that the height adjustment effect of the bottom of the rack 10 can be achieved, thereby ensuring a good leveling effect of the rack 10.

[0036] Furthermore, a push rod mechanism is provided on the side of the frame 10 away from the disc separation mechanism 50, which can achieve a good pushing effect, thereby achieving the effect of assisting the separation of the foam discs.

[0037] Preferably, the push rod mechanism includes: a mounting plate arranged on the frame 10, a cylinder facing the foam plate is horizontally arranged on the mounting plate, and a push rod is arranged at the output end of the cylinder.

[0038] like Figure 2 As shown, the present application also relates to a control method for a tobacco seedling foam tray feeding machine, comprising the tobacco seedling foam tray feeding machine; The following steps are also included: Initialization steps: After the control system is powered on, complete sensor zeroing, parameter loading and current disk and bin status detection; Specifically, various sensors (position sensors, vision modules, photoelectric / laser sensors, etc.) are zeroed and calibrated; Load the current system operating parameters (such as disk model, operating speed, initial value of width adjustment, etc.); Check whether there are foam trays in the current stack and the remaining height; It can ensure that each module of the system is in the initial effective state, prevent operation deviation, and improve the reliability and efficiency of the overall startup.

[0039] Size recognition and adjustment: The visual recognition module collects images of the foam disk, automatically identifies the width, shape and posture of the disk, and controls the automatic width adjustment mechanism 60 to adjust the guide spacing; Specifically, the visual recognition module collects images of foam discs in the disc storage bin, and the recognition content includes: The outer contour edge, corner feature points, and body posture angle of the foam plate; Automatically measure the actual width of the foam tray and identify whether it is a valid tray; Based on the recognition results, the control system drives the automatic width adjustment mechanism (such as sliding guide rails, motor + screw combination mechanism) to automatically adjust the distance between the two sides of the guide structure to adapt it to the current disk width.

[0040] Image recognition utilizes a multi-algorithm fusion strategy combining edge fitting and corner detection, resulting in enhanced robustness and environmental adaptability, ensuring high-precision and real-time recognition of foam disc size and position. It can automatically adapt to different foam disc models, reducing manual intervention and improving system versatility and automatic recognition and adjustment efficiency.

[0041] Disk separation operation: control the lifting assembly to lower the limiter to the specified position to contact the foam disk; Specifically, by controlling the movement of the lifting assembly, the limiting component is gradually lowered from the top to the set height, contacting the top foam plate to form a temporary blockage; Keep the foam tray at the bottom open to ensure that the tray separation mechanism can stably separate the individual trays below. Synchronously detect whether the limiter position is in place and feedback the signal to the control system.

[0042] It can form a reliable tray preparation station, effectively prevent multiple trays from being fed in by mistake or the tray body from tilting, and ensure the stability of the tray feeding process.

[0043] Release: The foam discs that are not in contact with the disc separation mechanism 50 are released in an orderly manner to complete the single disc delivery; Specifically, the control system drives the disc separation mechanism to start, releasing only the current bottom target foam disc: The lower foam disc that is not in contact with the limiting component is released in an orderly manner under the guidance of the disc separation assembly; The upper foam plate is still temporarily supported by the limiting parts and remains stationary.

[0044] Ensure the feeding principle of "only one tray at a time" to avoid feeding errors such as double trays and duplicate trays, and improve the accuracy of tray sorting.

[0045] Conveying and guiding: The conveying mechanism 30 is controlled to start, and the foam plate is conveyed along a predetermined path, while the automatic guiding structure performs alignment correction; Specifically, the separated foam discs are transported via a conveying mechanism, and the process includes: Start the conveying motor / belt to drive the foam tray to move forward along the conveying path of the carrying platform; The automatic guidance structure is started synchronously to perform real-time alignment correction based on the positioning results of the vision module; Realize trajectory correction and posture adjustment of foam trays during transportation.

[0046] It can improve the straightness and positioning accuracy of foam disc transportation, facilitate docking with subsequent sowing, transplanting and other equipment, and enhance the overall system collaboration performance.

[0047] Status judgment: judge whether the foam plate is in place, whether the plate is supplied successfully, and whether the plate is exhausted. If there is any abnormality, the control system will issue an alarm.

[0048] Specifically, the system has status monitoring logic in each key link to make real-time judgments: Whether the foam tray is successfully delivered to the right place; Whether there are any disc supply failures such as chucked discs, crooked discs, etc. Whether the current stack bin is empty or the height of the bin is below the warning line.

[0049] When the system determines that the supply disk is abnormal or about to be exhausted: Start alarm prompts (sound and light alarms, HMI interface pop-up windows); If a spare stacking bin is configured, it can automatically control the switch and continue to supply disks; Synchronously record log data and output it to the control terminal or host computer system.

[0050] Improve the system's intelligent monitoring and fault response capabilities to ensure the safety and stability of continuous tray supply operations.

[0051] Furthermore, the visual recognition module collects the foam disk image, including: Automatically identifying the size of the foam tray uses an image recognition algorithm based on edge fitting and corner detection. The width of the guide mechanism is adjusted in real time based on the results. This ensures accurate image recognition.

[0052] Furthermore, it also includes: The stack height determination step uses a laser / photoelectric sensor installed in the stack bin to monitor the number of remaining foam discs in real time. If the number falls below a preset threshold, the control system issues a refill prompt or automatically switches to a backup stack bin. This allows for real-time height determination.

[0053] Specifically, the laser / photoelectric sensor installed inside the stacking bin detects the height or number of remaining disks in real time: Upload the detection data to the control system in real time; If the detection value is lower than the set threshold, the system will trigger a refill prompt (sound and light / interface prompt); If equipped with a spare stacking bin structure, the switching logic can be automatically started to allow the spare stacking bin to take over the pallet supply process.

[0054] It can avoid machine downtime caused by unexpected exhaustion of foam trays, and improve operation continuity and the intelligent level of tray supply management.

[0055] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
