Description

Technical Field

[0001] This application relates to the field of production line adjustment technology, and in particular to methods, equipment, storage media and products for adjusting production spacing. Background Technology

[0002] Glass production lines require inline roller conveyors to transport glass for further processing, enabling automatic feeding into the tempering furnace. Continuous tempering equipment has stringent requirements for production spacing, necessitating timely adjustments. Currently, adjusting the production spacing of inline conveyor equipment in glass production lines relies on manual operation, making it difficult to adapt to production conditions promptly. This can lead to increased production spacing or discontinuous production, ultimately impacting the quality of the produced glass. Summary of the Invention

[0003] The main objective of this application is to provide a method, device, storage medium, and product for adjusting production spacing, aiming to solve the technical problem of poor production spacing adjustment effect.

[0004] To achieve the above objectives, this application proposes a method for adjusting production spacing, the method comprising: When the glass sheet is conveyed on the tension-variable speed roller conveyor, the photon status of each photon on the tension-variable speed roller conveyor is acquired. The photon status includes a signal state and a no-signal state. When the glass sheet is above the photon, the photon is in a signal state. When the glass sheet is not above the photon, the photon is in a no-signal state. Based on the state of the photoelectric sensor, the transmission control of the tension variable speed roller conveyor, the tension straightening roller conveyor, and the tension transition roller conveyor is performed to adjust the production spacing of the glass sheets.

[0005] In one embodiment, along the transport direction of the glass sheet, the photoelectric eyes are sequentially designated as a first photoelectric eye, a second photoelectric eye, a third photoelectric eye, and a fourth photoelectric eye. The step of controlling the transport of the tension-variable speed roller conveyor, the tension-aligning roller conveyor, and the tension-transition roller conveyor based on the states of the photoelectric eyes includes: Based on the states of the first and second photodetectors, the transmission states of the stretching and straightening roller conveyor and the stretching and transition roller conveyor are controlled. The speed of the tension variable speed roller conveyor is controlled based on the photon states of the first, second, third, and fourth photons.

[0006] In one embodiment, the step of determining the transmission status of the stretching and transition roller conveyor based on the photodetector states of the first and second photodetectors includes: When the first photodetector changes from a no-signal state to a signal state, the tension transition roller conveyor is adjusted to a stop-transmission state. When the first photodetector changes from a signal-enabled state to a signal-free state, the glass sheet on the stretch transition roller conveyor is transferred to the stretch aligning roller conveyor. If the first photodetector is in a no-signal state, when the second photodetector changes from a signal state to a no-signal state, after a preset first delay, the glass sheet on the stretching and straightening roller conveyor is transferred to the stretching and variable speed roller conveyor for subsequent transfer of the glass sheet.

[0007] In one embodiment, the tension-variable speed conveyor is provided with a first sub-tension-variable speed conveyor between the first photoelectric sensor and the second photoelectric sensor, a second sub-tension-variable speed conveyor between the second photoelectric sensor and the third photoelectric sensor, and a third sub-tension-variable speed conveyor between the third photoelectric sensor and the fourth photoelectric sensor. The step of controlling the speed of the tension-variable speed conveyor based on the photoelectric sensor states of the first photoelectric sensor, the second photoelectric sensor, the third photoelectric sensor, and the fourth photoelectric sensor includes: When the first photodetector and the second photodetector are in a no-signal state, the speed of the first sub-pitch variable speed roller is adjusted to the preset line speed. When the first photodetector, the second photodetector, and the third photodetector are in a no-signal state, the speed of the second sub-pitch variable speed roller is adjusted to the connecting line speed; When the first, second, and fourth photodetectors are in a no-signal state, and the third photodetector is in a signal state, the third sub-roller is adjusted to the connecting speed.

[0008] In one embodiment, the production spacing adjustment device is provided with multiple pre-processing lines, and the production spacing of each pre-processing line is the same. The production spacing adjustment method further includes: Obtain the number of glass slides processed on each of the preprocessing lines; If there is a pre-processing line where the number of glass sheets processed exceeds zero for a preset time, then the stretching stage of the pre-processing line is obtained, wherein the stretching stage corresponds to the preset production spacing between each glass sheet on the pre-processing line; If the stretching stage is not the preset maximum stretching stage, then the stretching stage of the preprocessed line is increased step by step until the preprocessed line reaches the maximum stretching stage. If the number of glass slides processed on each of the preprocessing lines is not zero, then the stretching stage of the preprocessing line is obtained. If the stretching stage is not the preset minimum stretching stage, then the stretching stage of the preprocessed line is gradually reduced until the preprocessed line reaches the minimum stretching stage.

[0009] In one embodiment, the preprocessing line of the production spacing adjustment equipment is further provided with a wafer storage platform, and the production spacing adjustment method further includes: Obtain the existing number of wafers stored in the wafer storage station, and calculate the number of wafers required for the wafer storage station based on the existing number of wafers stored and the preset number of wafers stored in the wafer storage station; Determine whether the glass sheet exists on the pretreatment line after the storage stage; If not, the storage stage is controlled to unload the stored glass slides onto the preprocessing line, and the number of replacement slides is increased accordingly. If the number of replacement sheets is greater than zero, the preceding process storage station is controlled to unload the stored glass sheets onto the preprocessing line, and the number of replacement sheets is reduced accordingly, so that the storage station can perform replacement operations. If the number of glass sheets already stored on the storage platform after patching is greater than the preset number of glass sheets, the process returns to the step of determining whether there is a glass sheet on the preprocessing line after the storage platform, until the number of glass sheets already stored on the storage platform is less than the preset number of glass sheets, at which point the patching operation ends, and the storage platform is controlled to continuously unload the stored glass sheets onto the preprocessing line.

[0010] In one embodiment, the production spacing adjustment equipment is further provided with a subsequent furnace unloading processing line, the furnace unloading processing line being provided with a furnace transition roller conveyor where multiple processing lines converge, and the production spacing adjustment method further includes: If the furnace pressing mode is enabled, then obtain the number of remaining wafers in the furnace pressing line. Determine whether the number of remaining pieces in the furnace is greater than zero; If the number of remaining sheets in the furnace is greater than zero, then it is determined whether there are any glass sheets on the transition roller conveyor of the furnace. If so, remove the glass sheet from the current press furnace, control the press furnace transition roller to transfer the glass sheet on the press furnace transition roller to perform the press furnace operation, reduce the number of remaining sheets in the press furnace by the corresponding transfer quantity, and return to the step of determining whether the number of remaining sheets in the press furnace is greater than zero, until the number of remaining sheets in the press furnace is not greater than zero, and end the press furnace operation.

[0011] Furthermore, to achieve the above objectives, this application also proposes a production spacing adjustment device, wherein the production spacing adjustment device is equipped with a pre-processing line, the pre-processing line comprising: A variable-speed pulley conveyor is provided with multiple photocells and multiple sub-variable-speed pulley conveyors. The variable-speed pulley conveyor is used to transport glass sheets to the loading stage. A stretching and straightening roller conveyor, which is connected to the stretching and variable speed roller conveyor, is used to align the glass sheet and transport the glass sheet to the stretching and variable speed roller conveyor. A stretch transition roller conveyor, which is connected to the stretch plate straightening roller conveyor, is used to transfer the glass sheet to the stretch plate straightening roller conveyor.

[0012] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the production spacing adjustment method described above.

[0013] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the production spacing adjustment method described above.

[0014] One or more technical solutions proposed in this application have at least the following technical effects: When the glass sheet is conveyed on the stretching variable speed roller conveyor, this application acquires the photocell status of each photocell on the stretching variable speed roller conveyor. The photocell status includes a signal state and a no-signal state. When the glass sheet is above the photocell, the photocell is in a signal state; when the glass sheet is not above the photocell, the photocell is in a no-signal state. Based on the photocell status, the conveying control of the stretching variable speed roller conveyor, the stretching straightening roller conveyor, and the stretching transition roller conveyor is performed to adjust the production spacing of the glass sheet.

[0015] To address the problem that current glass production lines rely on manual operation for adjusting the production spacing of inline conveyor equipment, making timely adjustments difficult based on production conditions, leading to increased production spacing or discontinuous production, ultimately affecting the quality of the produced glass, this application addresses this issue by acquiring the photocell status of each photocell on the variable-speed tension roller conveyor during the glass sheet's transport. Since the photocell signal status is related to the presence of a glass sheet above the photocell, acquiring the photocell status of each photocell allows determination of the glass sheet's transport status on the variable-speed tension roller conveyor. Therefore, based on the photocell status, this application controls the transport of the variable-speed tension roller conveyor, the tension straightening roller conveyor, and the tension transition roller conveyor. This enables control of the transport spacing between glass sheets based on their transport status on the variable-speed tension roller conveyor, eliminating the need for manual operation and achieving timely automatic control of the glass sheet production spacing, thereby preventing any impact on the quality of the produced glass.

[0019] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0022] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or production spacing adjustment device capable of performing the above functions. The following description uses a production spacing adjustment device as an example to illustrate this embodiment and the subsequent embodiments.

[0023] The research and development background or motivation for this application is as follows: With the development of the photovoltaic glass industry, some details of the connecting equipment in many photovoltaic glass deep processing lines need to be improved. The glass production line, including the connecting roller conveyor (including the storage roller conveyor) after deep processing of glass, needs to transport glass and the tempering furnace automatically feeds the sheets. However, the adjustment of the spacing still relies on manual operation, which has a low degree of automation and is prone to errors. It cannot be adjusted in time according to the production situation. If the connecting process equipment in the front end malfunctions, the insufficient glass supply will frequently lead to an increase in the production spacing or discontinuous production. If the production spacing is not adjusted in time, it will affect the quality of the produced glass, and frequent start-ups and shutdowns will also affect the output and power consumption.

[0024] In addition, the current tempering furnace pressing and unloading of glass sheets in the glass production line relies on manual operation, requiring four people to work together, which occupies a lot of personnel, and the glass unloading method needs to be improved.

[0025] Based on this, embodiments of this application provide a method for adjusting production spacing, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the production spacing adjustment method of this application.

[0026] In this embodiment, the production spacing adjustment method includes steps S10~S20: Step S10: When the glass sheet is conveyed on the tension-variable speed roller conveyor, the photon status of each photon on the tension-variable speed roller conveyor is obtained. The photon status includes a signal state and a no-signal state. When the glass sheet is above the photon, the photon is in a signal state. When the glass sheet is not above the photon, the photon is in a no-signal state. It should be noted that a variable-speed roller conveyor refers to a conveyor section in a production line composed of multiple independently adjustable rollers. The conveyor speed and the spacing between adjacent glass sheets can be adjusted by changing the roller speed. A photoelectric sensor is a photoelectric sensor used to detect the presence of an object. When an object blocks the light path, it generates a change in electrical signal. The photoelectric sensor's status refers to the current output signal state, which is divided into a signal-on state and a signal-off state. A signal-on state means that the photoelectric sensor's light path is blocked by a glass sheet, the sensor detects the object's presence, and outputs a high-level signal or a conducting signal. A signal-off state means that the photoelectric sensor's light path is not blocked, the sensor does not detect an object, and outputs a low-level signal or a disconnected signal.

[0027] Understandably, current control of the glass sheet spacing in tempering production lines relies heavily on manual experience or simple timing control, lacking real-time sensing of the glass sheet's actual position. This leads to an inability to adjust the subsequent conveying rhythm in time when upstream equipment malfunctions or the sheet supply is discontinuous, easily resulting in excessively large or small glass sheet spacing. This affects the stability of the thermal field within the tempering furnace, potentially causing product quality fluctuations or even production interruptions. This embodiment addresses this by arranging multiple photodetectors on the variable-speed roller conveyor to collect real-time status information from each photodetector, accurately determining the glass sheet's position and movement during conveyance, and providing real-time and accurate position feedback for the subsequent automated control system.

[0028] Specifically, in this embodiment, each photocell acts as an independent detection point, and its state change corresponds to the moment when the head or tail of the glass sheet passes through that point. This precise timing information allows the control system to accurately grasp the position and movement trend of each glass sheet, thereby achieving refined timing control. Through this closed-loop mechanism based on physical position feedback, the system can dynamically adapt to changes in production rhythm, avoiding spacing loss due to human judgment delays or errors. This effectively reduces glass spacing fluctuations, ensures continuous furnace feeding, reduces energy consumption and equipment wear caused by frequent start-ups and shutdowns, and ultimately improves product quality and production efficiency.

[0029] Step S20: Based on the state of the photoelectric sensor, the transmission control of the tension variable speed roller conveyor, the tension straightening roller conveyor, and the tension transition roller conveyor is performed to adjust the production spacing of the glass sheets.

[0030] It should be noted that the stretching and aligning roller conveyor refers to the roller conveyor used for positioning and orientation correction of the glass sheets, ensuring that the glass sheets enter the subsequent processes in the correct posture. In this embodiment, the stretching and aligning roller conveyor is used for temporary storage and alignment of the glass sheets before they enter the stretching variable speed roller conveyor. The stretching transition roller conveyor refers to the intermediate conveyor section connecting different functional roller conveyors, used to smoothly transfer the glass sheets and avoid jamming or collisions during the transmission process. In this embodiment, it is used to temporarily store subsequent glass sheets. The production spacing refers to the longitudinal distance maintained between two adjacent glass sheets before entering the tempering furnace. It is a key parameter affecting the thermal stability of the tempering furnace and product quality, and needs to be precisely controlled according to process requirements. The layout of the connecting equipment in this embodiment can be referred to Figure 2 The layout of the tension-variable speed roller conveyor in this embodiment can be referred to Figure 3 .

[0031] It is understood that, based on the acquired photoelectric state information, this embodiment dynamically adjusts the start, stop and speed of the tension-variable speed roller conveyor, the tension-aligning roller conveyor and the tension-transition roller conveyor through the control system to achieve precise control of the glass sheet transmission rhythm.

[0032] In one feasible implementation, along the transport direction of the glass sheet, the photoelectric eyes are sequentially designated as a first photoelectric eye, a second photoelectric eye, a third photoelectric eye, and a fourth photoelectric eye. The specific implementation of controlling the transport of the tension-variable speed roller conveyor, the tension-aligning roller conveyor, and the tension-transition roller conveyor based on the states of the photoelectric eyes can also be: Based on the states of the first and second photodetectors, the transmission states of the stretching and straightening roller conveyor and the stretching transition roller conveyor are controlled. Based on the states of the first, second, third, and fourth photodetectors, the speed of the stretching variable speed roller conveyor is controlled.

[0033] It should be noted that the first, second, third, and fourth photoelectric sensors refer to four photoelectric sensors arranged sequentially along the glass sheet conveying direction on the tension-variable speed roller conveyor. These sensors are used to detect the state of the glass sheet at different positions, and their numbers correspond to spatial order, enabling segmented control. In this embodiment, the glass sheet conveying direction refers to the direction of movement of the glass sheet from the previous process through the tension-adjusting roller conveyor and the tension-variable speed roller conveyor, finally entering the tempering furnace. The logic control flow for adjusting the production spacing in this embodiment can be referred to... Figure 4 .

[0034] Understandably, this implementation method numbers the four photoelectric sensors according to the transmission direction and assigns them specific functions based on their positions. This embodiment utilizes the states of the first and second photoelectric sensors to primarily control the start and stop of the tension-adjusting roller conveyor and the tension-transition roller conveyor, ensuring that the glass sheets enter the variable speed zone in sequence. Simultaneously, by comprehensively considering the states of the first to fourth photoelectric sensors, the speed of the tension-variable speed roller conveyor is finely adjusted, achieving smooth acceleration and synchronization of the glass sheets within the variable speed zone. This modular division of control functions improves the system's response accuracy and stability, effectively avoids collisions or excessive spacing between glass sheets, and enhances the production line's adaptability to abnormal operating conditions.

[0035] Specifically, in this embodiment, the first photodetector is located at the entrance of the tension-variable speed conveyor. Its signal indicates that a glass sheet is entering the variable speed zone. At this time, the system should prevent subsequent glass sheets from entering, so the tension transition roller conveyor is stopped, causing the glass sheet to stop in front of the tension-aligning roller conveyor. When the first photodetector returns to a no-signal state, it indicates that the sheet has fully entered the variable speed zone, and the next sheet can be allowed to enter the tension-aligning roller conveyor for preparation. The second photodetector is located in the middle of the variable speed zone. Its combined state with the first photodetector can be used to determine whether the glass sheet has stabilized and further confirm whether the next sheet can be started. The third and fourth photodetectors are used for speed control. When the head of the glass sheet passes the fourth photodetector, the system starts a delay program, gradually adjusting the speed of the tension-variable speed conveyor to the synchronous speed of the loading platform. When the tail leaves the second photodetector, the start delay for the next sheet is triggered.

[0036] This embodiment achieves phased and refined control of the glass sheet transfer process through the above steps, avoiding control errors caused by misjudgment by a single optical eye. It also improves the robustness of the system through multi-point feedback, making the glass sheet spacing adjustment more stable and precise. It effectively reduces the impact caused by sudden speed changes or asynchronous start-stop, ensuring the continuity of the tempering furnace feed and the stability of the thermal field, thereby improving product quality and production efficiency.

[0037] In one feasible implementation, the specific implementation of the transmission state of the stretching and transition roller conveyor based on the photon states of the first and second photons can also be: When the first photodetector changes from a no-signal state to a signal state, the stretch transition roller is adjusted to a stop transmission state. When the first photodetector changes from a signal state to a no-signal state, the glass sheet on the stretch transition roller is transferred to the stretch alignment roller. If the first photodetector is in a no-signal state, when the second photodetector changes from a signal state to a no-signal state, after a preset first delay, the glass sheet on the stretch alignment roller is transferred to the stretch variable speed roller for subsequent transmission of the glass sheet via the stretch variable speed roller.

[0038] It should be noted that the change from a no-signal state to a signal state indicates that the head of the glass sheet has reached the photon position and begins to block the light path. The change from a signal state to a no-signal state indicates that the tail of the glass sheet has left the photon position and the light path has been restored. The stop transmission state means that the rollers of the tension transition roller conveyor stop rotating, keeping the glass sheet in place and preventing it from moving forward. The preset first delay is a fixed or adjustable time interval set by the system. It is used to delay the start of the next glass sheet entering the tension variable speed roller conveyor after the tail of the previous glass sheet leaves the second photon, so as to ensure a safe distance.

[0039] Understandably, current glass sheet transport control often relies on fixed delays or manual judgment to determine the start-up timing of subsequent glass sheets, which can easily lead to uneven glass spacing or rear-end collisions. This embodiment controls the transport status of the tensioning and transition roller conveyors by accurately identifying the state changes of the first and second photodetectors. This embodiment, by accurately determining the movement stage of the glass sheet through the timing relationship of photodetector state changes, achieves precise start-stop control based on the actual position of the glass sheet, effectively avoiding collisions between glass sheets and improving the automation and safety of the transport process.

[0040] Specifically, when the first photodetector changes from no signal to a signal, it indicates that the head of the current glass pane has just entered the stretching and speed-changing roller conveyor. If subsequent glass panes are not stopped in time, they may overlap or collide in the speed-changing zone. Therefore, the system immediately stops the stretching and transition roller conveyor to ensure that subsequent glass panes remain in a safe position. When the first photodetector returns to no signal, it indicates that the glass pane has fully entered the speed-changing zone and will not obstruct subsequent glass panes from entering the stretching and straightening roller conveyor. The system can then allow the next glass pane to enter the stretching and straightening roller conveyor for positioning, preparing for subsequent acceleration. When the second photodetector changes from a signal to no signal, it indicates that the tail of the previous glass pane has passed the middle of the speed-changing zone. At this time, the system initiates a preset first delay. After this delay, the glass pane on the stretching and straightening roller conveyor is sent into the stretching and speed-changing roller conveyor. This delay ensures that a sufficient physical distance is formed between the two glass panes, avoiding rear-end collisions due to acceleration differences during speed synchronization. Therefore, this embodiment achieves precise control of the glass sheet conveying rhythm through the above-described specific control process. This not only improves control accuracy but also enhances the system's adaptability to different glass sizes and production rhythms, thereby ensuring the continuity and stability of the tempering furnace feed and reducing downtime and scrap rates caused by uncontrolled spacing.

[0041] In one feasible implementation, the tension-variable speed conveyor is provided with a first sub-tension-variable speed conveyor between the first and second photoelectric eyes, a second sub-tension-variable speed conveyor between the second and third photoelectric eyes, and a third sub-tension-variable speed conveyor between the third and fourth photoelectric eyes. A further specific implementation of controlling the speed of the tension-variable speed conveyor based on the photoelectric eye states of the first, second, third, and fourth photoelectric eyes can be: When the first and second photodetectors are in a no-signal state, the speed of the first sub-pitch variable speed roller conveyor is adjusted to the preset connecting speed. When the first, second, and third photodetectors are in a no-signal state, the speed of the second sub-pitch variable speed roller conveyor is adjusted to the connecting speed. When the first, second, and fourth photodetectors are in a no-signal state, and the third photodetector is in a signal state, the third sub-roller conveyor is adjusted to the connecting speed.

[0042] It should be noted that the first sub-pitch variable speed roller conveyor is the segment located between the first and second photocells, responsible for the initial transmission control of the glass sheet. The second sub-pitch variable speed roller conveyor is the segment located between the second and third photocells, responsible for accelerating or maintaining a constant speed in the middle section of the glass sheet. The third sub-pitch variable speed roller conveyor is the segment located between the third and fourth photocells, mainly used for speed matching before the glass sheet approaches the loading table. The line speed refers to the operating speed of downstream equipment such as the loading table or tempering furnace inlet on the production line. It is the target speed that each sub-segment of the pitch variable speed roller conveyor needs to recover when no glass passes through, used to ensure consistent production rhythm and avoid idling and lag.

[0043] Understandably, current methods for adjusting the speed of variable-speed roller conveyors typically employ overall speed regulation or fixed zone control, making it difficult to dynamically adjust the speed of each segment based on the actual distribution of the glass sheets. This results in idle sections maintaining low-speed operation, affecting the rapid follow-up of subsequent glass sheets and causing fluctuations in the furnace entry spacing. This implementation divides the variable-speed roller conveyor into three sub-segments and dynamically controls the speed of each sub-segment based on the combination of photocell status. By dynamically managing the speed of each segment of the variable-speed roller conveyor, the flexibility and accuracy of speed control are improved, ensuring that subsequent glass sheets can be replenished at the fastest speed and maintaining a stable production rate.

[0044] Specifically, when both the first and second photodetectors show no signal, it indicates that there is no glass sheet present in the area between the entrance and the second photodetector. If the system continues to operate at a low speed at this point, the next piece of glass will need to be started at a low speed, affecting the overall production speed. Therefore, the system immediately increases the speed of the first sub-pitch variable speed roller conveyor to the line speed, allowing the next piece of glass to enter directly at high speed, reducing acceleration time and shortening the furnace feeding cycle.

[0045] When the first, second, and third photodetectors all show no signal, it indicates that the glass sheet has completely passed through the second sub-pitch variable speed roller conveyor area. If this section continues to operate at a low speed, it will affect the transmission efficiency of subsequent glass sheets. Therefore, the system restores the second sub-pitch variable speed roller conveyor to its continuous speed, creating conditions for the rapid passage of the next glass sheet and avoiding slowing down the overall cycle time due to the previous section being idle.

[0046] When the first, second, and fourth photodetectors are not transmitting a signal, while the third photodetector is transmitting a signal, it indicates that the glass sheet is currently on the third sub-pitch variable speed roller conveyor (blocking the third photodetector), but has not yet reached the position of the fourth photodetector. At this time, the system determines that this section is about to be cleared, and there is no glass sheet following immediately. Therefore, the third sub-pitch variable speed roller conveyor can be adjusted to the connecting speed in advance, so that it immediately enters a high-speed standby state after the glass sheet passes through, preparing for the insertion of the next glass sheet.

[0047] This embodiment, through the aforementioned speed control method for variable-speed roller conveyors based on multi-eye state combinations, achieves refined perception and response to the operating status of each segment of the variable-speed roller conveyor. Each segment immediately resumes high speed after confirming no glass obstruction, avoiding the wasted production time of waiting at low speeds for entire segments in traditional control methods. This significantly shortens the minimum controllable distance between glass sheets and enhances the production line's adjustment capabilities. Simultaneously, because each segment can quickly return to its connecting speed, the impact of speed fluctuations on the transmission system is reduced, extending equipment lifespan and ensuring the continuity and stability of the glass flow at the tempering furnace inlet, ultimately improving product quality and production efficiency.

[0048] In summary, in this embodiment, when the glass sheet is conveyed on the stretching variable speed roller conveyor, the photoelectric state of each photoelectric sensor on the stretching variable speed roller conveyor is acquired. The photoelectric state includes a signal state and a no-signal state. When the glass sheet is above the photoelectric sensor, the photoelectric sensor is in a signal state; when the glass sheet is not above the photoelectric sensor, the photoelectric sensor is in a no-signal state. Based on the photoelectric state, the conveying control of the stretching variable speed roller conveyor, the stretching straightening roller conveyor, and the stretching transition roller conveyor is performed to adjust the production spacing of the glass sheet.

[0049] To address the problem that current glass production lines rely on manual operation for adjusting the production spacing of inline conveyor equipment, making timely adjustments difficult based on production conditions, leading to increased production spacing or discontinuous production, ultimately affecting glass quality, this embodiment acquires the photocell status of each photocell on the variable-speed pulley conveyor during glass sheet transport. Since the photocell signal status is related to the presence of a glass sheet above the photocell, acquiring the photocell status of each photocell determines the glass sheet's transport status on the variable-speed pulley conveyor. Therefore, this embodiment controls the transport of the variable-speed pulley conveyor, the pull-up pulley conveyor, and the pull-down pulley based on the photocell status. This allows for control of the transport spacing between glass sheets based on their transport status on the variable-speed pulley conveyor, eliminating the need for manual operation and enabling timely automatic control of the glass sheet production spacing, thereby preventing any impact on the quality of the produced glass.

[0050] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 5 The production spacing adjustment equipment is equipped with multiple pre-processing lines, and the production spacing of each pre-processing line is the same. The production spacing adjustment method further includes steps S100~S500: S100, obtain the number of glass slides processed on each of the preprocessing lines; It should be noted that a pretreatment line refers to a production line that performs various processing steps on glass sheets before the tempering process. Typically, multiple pretreatment lines share a single tempering line, serving as a preparatory stage before the glass enters the main furnace. The glass sheet processing quantity refers to the number of glass sheets currently being processed or ready for transport on a particular pretreatment line, reflecting the line's supply capacity and continuity.

[0051] Understandably, current methods for controlling the glass feed spacing in tempering furnaces primarily rely on manual observation or fixed-time operation. When a pretreatment line experiences a malfunction or shutdown leading to an interruption in glass supply, the system cannot detect insufficient supply in advance. Adjustments are often made passively only after a break in the glass flow occurs, resulting in abrupt changes in the feed spacing and causing drastic temperature fluctuations within the tempering furnace, impacting product quality. This step, by acquiring real-time data on the number of glass sheets processed on each pretreatment line and understanding the real-time supply status of each line, provides data support for subsequent automatic spacing decisions.

[0052] S200, if there is a pre-processing line where the number of glass sheets processed exceeds zero for a preset time, then the stretching stage of the pre-processing line is obtained, wherein the stretching stage corresponds to the preset production spacing between each glass sheet on the pre-processing line; It should be noted that "zero glass sheet processing quantity" means that there are currently no glass sheets being processed or waiting to be conveyed on a certain pre-processing line, indicating that the line is in a no-feed state. "Exceeding the preset time" means that the duration of the zero glass sheet processing quantity state exceeds a threshold set by the system, used to distinguish between short-term fluctuations and substantial supply interruptions, avoiding accidental triggering of the stretching operation. The stretching stage refers to multiple graded control levels set by the system to cope with insufficient supply. Each stage corresponds to a different glass entry spacing, used to gradually adjust the production rhythm. The preset production spacing refers to the target spacing value set by the control system for adjacent glass sheets at different stretching stages, which usually increases as the stretching stage increases to adapt to furnace temperature changes. The automatic stretching setting in this embodiment can be referred to... Figure 6 The automatic distance adjustment process can be referred to Figure 7 .

[0053] Understandably, in current methods, when a pretreatment line stops feeding, the system often only makes significant spacing adjustments after the glass flow is completely interrupted. This leads to a sharp drop in heat load and drastic temperature fluctuations within the tempering furnace, affecting glass production instructions. This embodiment determines a substantial feeding interruption when it detects that the number of glass sheets processed on a pretreatment line is zero and the duration exceeds a preset threshold. It then obtains the corresponding tension stage, selecting the initial tension level based on the current feeding situation. This allows the system to choose an appropriate tension scheme based on the degree of interruption, avoiding excessive or insufficient control actions and improving the accuracy and stability of the adjustment.

[0054] Specifically, this embodiment uses a preset time as a judgment criterion to effectively distinguish between instantaneous signal interference and actual material supply interruptions. For example, if the processing quantity of a certain line is zero but only lasts for 5 seconds, it may be a temporary buffer adjustment, and there is no need to start the pull-out interval; however, if it lasts for more than 30 seconds, it indicates that the equipment has stopped and the furnace feeding rhythm must be adjusted. This time filtering mechanism avoids frequent pull-out intervals caused by misjudgments, improving system stability. When a material supply interruption is confirmed, the system does not immediately execute the maximum spacing adjustment, but rather obtains the pull-out interval stage, that is, determines the initial pull-out interval stage based on the current overall material supply situation, and performs pull-out intervals in stages. This embodiment avoids drastic adjustments to the pull-out interval in a single operation, but instead adopts a stepped pull-out interval, allowing the tempering furnace thermal field to gradually adapt to load changes, resulting in smoother temperature fluctuations. This ensures the rationality and stability of the pull-out interval action, effectively reduces the rate of temperature change, ensures stable glass quality, and extends equipment life.

[0055] S300, if the stretching stage is not the preset maximum stretching stage, then the stretching stage of the preprocessed line is increased step by step until the preprocessed line reaches the maximum stretching stage; It should be noted that the preset maximum tension stage refers to the highest tension level set by the system, corresponding to the maximum furnace inlet spacing. The tension stages are increased gradually in a preset order, rather than jumping to the highest stage all at once, to ensure a smooth transition in the control process.

[0056] Understandably, current methods often respond to interruptions in the pretreatment line supply by immediately increasing the spacing or shutting down the machine, leading to a sharp drop in temperature within the tempering furnace and significant temperature fluctuations that impact the quality of the produced glass. This embodiment, when determining that the spacing stage has not reached its maximum value, gradually increases the spacing stage in stages, allowing the tempering furnace sufficient time to adapt to load changes. This avoids drastic temperature fluctuations caused by overly abrupt control actions, improving the stability of the production process and the consistency of product quality.

[0057] S400, if the number of glass sheets processed on each of the preprocessing lines is not zero, then the stretching stage of the preprocessing line is obtained. It should be noted that in current methods, when the pretreatment line resumes feeding, the control system often immediately restores the original furnace entry spacing, causing a large number of glass sheets to enter the tempering furnace in a short period of time. This results in rapid temperature changes in the tempering furnace, affecting the quality of the produced glass. In this embodiment, after determining that the number of glass sheets processed on all pretreatment lines is not zero, it indicates that the feeding has been fully restored. At this point, the normal spacing is not directly restored. Instead, the current tension stage is first obtained, that is, the current tension level of the system is confirmed, providing an initial tension stage for the subsequent gradual reduction of the spacing.

[0058] S500, if the stretching stage is not the preset minimum stretching stage, then the stretching stage of the preprocessed line is gradually reduced until the preprocessed line reaches the minimum stretching stage.

[0059] It should be noted that the preset minimum tension stage refers to the lowest tension level set by the system, which corresponds to the minimum furnace entry distance and represents the normal continuous operation state of the production line.

[0060] It is understandable that, as a high-temperature, closed thermal system, the tempering furnace exhibits significant lag and inertia in its internal temperature distribution and airflow circulation. If the furnace spacing is immediately jumped from its maximum value back to its minimum value after material supply resumes, the furnace temperature will rise rapidly, affecting the quality of the produced glass. Therefore, this embodiment employs a step-by-step reduction method to adjust the spacing during the drawing stage, resulting in a smoother furnace temperature change curve and preventing excessively rapid temperature changes from impacting the quality of the produced glass. Simultaneously, this step-by-step reduction method allows the control system to monitor furnace temperature feedback at each stage. If excessively rapid temperature rise is detected, the drawing stage can be paused or reversed, enhancing the system's adaptability. Therefore, this embodiment, through the aforementioned spacing adjustment, effectively mitigates the impact of resuming production on the tempering furnace, not only improving the glass yield but also reducing equipment wear and energy consumption fluctuations, ultimately achieving a transition from an abnormal state to normal production.

[0061] In one feasible implementation, a wafer storage platform is further provided on the preprocessing line of the production spacing adjustment equipment. The specific implementation of the production spacing adjustment method can also be: The system obtains the existing number of glass sheets stored in the glass storage station, and calculates the number of replacement sheets required by the station based on the existing number of glass sheets and the preset number of glass sheets stored in the station. It then determines whether the glass sheets exist on the preprocessing line following the glass storage station. If not, the system controls the glass storage station to unload the stored glass sheets onto the preprocessing line and increases the number of replacement sheets by the corresponding unloaded quantity. If the number of replacement sheets is greater than zero, the system controls the preceding glass storage station to unload the stored glass sheets onto the preprocessing line and decreases the number of replacement sheets by the corresponding unloaded quantity, allowing the glass storage station to perform replacement operations. If the existing number of glass sheets in the glass storage station after replacement is greater than the preset number of glass sheets, the system returns to the step of determining whether the glass sheets exist on the preprocessing line following the glass storage station, until the existing number of glass sheets in the glass storage station is less than the preset number of glass sheets. At this point, the replacement operation ends, and the system controls the glass storage station to continuously unload the stored glass sheets onto the preprocessing line.

[0062] It should be noted that the glass sheet storage table is a glass sheet temporary storage device arranged on the pretreatment line, which is used to release the stored glass sheets when the feeding is insufficient, or receive and store the excess glass when the feeding is sufficient, playing a buffering and regulating role. The existing number of stored sheets refers to the actual number of glass sheets stored on the current glass sheet storage table, and the preset number of stored sheets refers to the target storage capacity of the glass sheet storage table set by the system, which is used to maintain a reasonable buffering capacity and avoid excessive stacking or vacancy. The number of sheets to be supplemented refers to the number of glass sheets required to make the glass sheet storage table reach the preset number of stored sheets, which is the difference between the preset number of stored sheets and the existing number of stored sheets in this embodiment. Releasing sheets refers to the operation of controlling the glass sheet storage table to release the stored glass sheets and convey them to the downstream pretreatment line. The upstream process glass sheet storage table refers to another storage device located upstream of the current glass sheet storage table, which is used to supply glass sheets to the current glass sheet storage table to form a multi-level buffering structure. The automatic sheet supplementing process of this embodiment can be referred to Figure 8 .

[0063] It can be understood that in the current method, the glass sheet storage table usually uses a fixed logic for sheet supplementing or sheet releasing, lacking the linkage judgment of the upstream and downstream states, which is likely to cause untimely sheet supplementing or excessive sheet supplementing, affecting the continuity and stability of the glass flow. In this embodiment, by dynamically obtaining the existing number of stored sheets of the glass sheet storage table and calculating the number of sheets to be supplemented in combination with the preset number of stored sheets, and at the same time judging whether there are glass sheets on the downstream pretreatment line of the glass sheet storage table: if there is no glass, the glass is preferentially released downward by this glass sheet storage table to maintain the furnace feeding rhythm; if sheet supplementing is required and there is glass resource upstream, the upstream process glass sheet storage table is controlled to supplement sheets to the downstream glass sheet storage table, avoiding material breakage or congestion caused by improper sheet supplementing timing, and improving the adaptive ability and feeding continuity of the system.

[0064] Specifically, in this embodiment, by obtaining the existing number of stored sheets of the glass sheet storage table in real time and calculating the sheet supplementing demand, the system can accurately judge whether sheet supplementing is required and the number of sheets to be supplemented, and judge whether there is glass on the downstream pretreatment line before sheet supplementing, avoiding rear-end collision or congestion when releasing glass. When this glass sheet storage table needs to supplement sheets, it actively controls the upstream process glass sheet storage table to supply, realizing the coordinated scheduling between multi-level glass sheet storage tables. Through the above-mentioned loop judgment and sheet supplementing steps, it is ensured that the stored sheet quantity gradually approaches the preset value and stops sheet supplementing after reaching it to prevent overflow. Finally, in this embodiment, after sheet supplementing is completed, the glass sheet storage table is controlled to continuously release sheets to restore a stable feeding rhythm, thereby effectively reducing the fluctuation of the glass flow into the furnace, ensuring the stable temperature of the tempering furnace, and improving the production continuity and product quality.

[0065] In a feasible embodiment, the production spacing adjustment device is further provided with a subsequent press-furnace sheet-releasing treatment line, and a press-furnace transition roller table where multiple treatment lines converge is arranged on the press-furnace sheet-releasing treatment line. The specific implementation manner of the production spacing adjustment may also be: If the pressing furnace mode is enabled, the number of remaining sheets in the pressing furnace is obtained from the pressing furnace unloading processing line. It is then determined whether the number of remaining sheets is greater than zero. If the number of remaining sheets is greater than zero, it is determined whether there is a glass sheet on the pressing furnace transition roller. If there is, the glass sheet currently in the pressing furnace is removed, and the pressing furnace transition roller is controlled to transfer the glass sheet on the pressing furnace transition roller for pressing operation, thereby reducing the number of remaining sheets in the pressing furnace by the corresponding number of transfers. The process then returns to the step of determining whether the number of remaining sheets in the pressing furnace is greater than zero, until the number of remaining sheets in the pressing furnace is no longer greater than zero, at which point the pressing furnace operation ends.

[0066] It should be noted that in this embodiment, the equipment enters the connecting equipment at the unloading table. The glass state is determined by controlling the convergence of the glass with the transition rollers of the pre-press furnace before the robot arm, and a signal is sent to the robot arm to unload the sheet from the press furnace. The layout of the connecting equipment for unloading the sheet from the press furnace in this embodiment can be referred to... Figure 9 .based on Figure 9 In this embodiment, after passing through the press furnace, the glass is diverted via a vertical roller conveyor, cleaned by a cleaning machine, and finally reunited on the press furnace transition roller conveyor before the robotic arm. The full inspection roller conveyor needs to handle both the glass and the glass itself, and since the glass needs to be diverted and reunited, the judgment roller conveyor is located at the reunification point of the press furnace transition roller conveyor before the robotic arm to avoid misjudgments and missed judgments. The settings of the press furnace unloading program interface in this embodiment can be referred to... Figure 10 The automatic unloading process of the press furnace can be referred to Figure 11 .

[0067] Understandably, the current tempering furnace pressing and unloading process in glass production lines relies on manual operation, requiring four people to work together. This is labor-intensive, inefficient, and prone to errors. This implementation method, after activating the pressing furnace mode, first obtains the remaining number of sheets in the pressing furnace and checks if it is greater than zero. If it is, it indicates that there is still glass to be processed. At this point, it further checks whether there are glass sheets on the pressing furnace transition rollers. If so, it removes the currently invalid pressing furnace command, controls the glass sheet to enter the pressing furnace operation, and reduces the remaining number of sheets accordingly. By repeatedly executing this logic, each sheet is processed until the remaining number is zero. This implementation method, through the above steps, achieves sheet-by-sheet confirmation and orderly release during the pressing process, avoiding glass sheet accumulation or omissions, reducing workload, improving equipment automation, and thus reducing the possibility of errors due to manual operation. Furthermore, this implementation method optimizes the unloading logic through the above steps, reducing the time required to resume production, ensuring the stability of the glass production process, and improving glass quality.

[0068] In summary, this embodiment obtains the number of glass sheets processed on each preprocessing line. If there is a preprocessing line where the number of glass sheets processed exceeds zero for a preset time, then the stretching stage of the preprocessing line is obtained. The stretching stage corresponds to the preset production spacing between each glass sheet on the preprocessing line. If the stretching stage is not the preset maximum stretching stage, then the stretching stage of the preprocessing line is increased step by step until the preprocessing line reaches the maximum stretching stage. If the number of glass sheets processed on each preprocessing line is not zero, then the stretching stage of the preprocessing line is obtained. If the stretching stage is not the preset minimum stretching stage, then the stretching stage of the preprocessing line is decreased step by step until the preprocessing line reaches the minimum stretching stage.

[0069] In current methods, when the pretreatment line supply is interrupted or resumed, the control system often immediately increases the spacing, causing sudden temperature changes in the tempering furnace and affecting glass quality. This embodiment determines whether a supply interruption exists by real-time monitoring of the number of glass sheets processed on each pretreatment line. If a line's processing quantity is zero and continues to time out, the current spacing stage is determined, and the spacing is gradually increased before reaching the maximum stage, thus slowing down the rate of temperature drop in the tempering furnace. When all pretreatment lines have glass, the spacing stage is gradually decreased from the current stage, causing the furnace spacing to gradually shrink and preventing excessively rapid temperature changes in the tempering furnace. Therefore, this embodiment, through the multi-stage spacing of the production spacing described above, significantly improves the system's adaptability to production fluctuations, ensures the stability of the tempering furnace temperature, and thus prevents production fluctuations from affecting glass quality.
