Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging bag manufacturing, and in particular to a bag making method and a bag making system of a bag making device. BACKGROUND

[0002] The bag making device is a key device for manufacturing packaging bags, which can transport raw materials and sequentially complete steps such as sealing, forming, and bag arranging, and finally produce packaging bags meeting requirements. The positions of each bag making component (such as a sealing mechanism, a forming mechanism, and a bag arranging mechanism) on the bag making device need to strictly adapt to the size specifications of target packaging bags to ensure that the produced packaging bags are of consistent specifications. However, the demand for multiple varieties, small batches, and customization of packaging bags is gradually increasing. If multiple sizes of packaging bags are to be manufactured by the same bag making device, after producing a batch of packaging bags, the positions of each bag making component on the bag making device must be re-adjusted to adapt to the production of a new batch of packaging bags. Currently, the adjustment of the positions of bag making components mainly relies on manual operation, and the manual adjustment method greatly depends on the experience of operators and the complexity of the device, thus being extremely inefficient; and during adjustment, size deviations are likely to occur, and the precision is poor. Therefore, the existing bag making device needs to manually adjust the positions of bag making components when producing packaging bags of different specifications, which has the problems of low efficiency and poor precision. SUMMARY

[0003] The present application aims to solve the problem in the prior art that the positions of bag making components need to be manually adjusted when producing packaging bags of different specifications, which is inefficient and has poor adjustment precision. To solve the above problem, an embodiment of the present application discloses a bag making method of a bag making device, which comprises a rack, bag making components arranged on the rack, and a driving adjustment component connected with the bag making components. The bag making method comprises the following steps: powering on the bag making device, and running the bag making components to an initial position; obtaining first specification parameters of a first target product corresponding to an initial production cycle, determining a first target position of the bag making components according to the first specification parameters, and determining a position deviation between the initial position and a reference position of the bag making components; confirming the running state of the driving adjustment component to make the driving adjustment component run in a preset state; controlling the driving adjustment component to drive the bag making components to move from the initial position to the first target position according to the first target position and the position deviation; obtaining second specification parameters of a second target product corresponding to a current production cycle, and controlling the driving adjustment component to drive the bag making components to move from the first target position to a second target position according to the second specification parameters.

[0004] Using the above scheme, the drive adjustment component can precisely control the movement of the bag-making component to the target position based on the acquired product specification parameters and position deviation information. When producing products of different specifications, only the new specification parameters need to be input to automatically complete the position adjustment. Furthermore, during the initial production cycle, the drive adjustment component is controlled jointly based on the position deviation between the initial position and the reference position of the bag-making component and the first target position, which can eliminate mechanical errors generated during equipment installation. By confirming the operating status of the drive adjustment component, the efficiency and accuracy of moving the bag-making component to the target position are improved.

[0005] According to another specific embodiment of the present invention, the bag-making method of the bag-making equipment disclosed in this embodiment of the present invention determines the positional deviation between the initial position and the reference position of the bag-making component, including: defining the reference position of the bag-making component according to the standard installation position of the bag-making equipment when it leaves the factory; directly measuring the distance difference between the initial position and the reference position of the bag-making component using a measuring tool, and using the distance difference as the positional deviation.

[0006] By adopting the above scheme, using the standard installation position as a fixed reference point, and defining the reference position and directly measuring the distance, the position deviation can be accurately quantified.

[0007] According to another specific embodiment of the present invention, the bag-making method of the bag-making equipment disclosed in this embodiment of the present invention determines the positional deviation between the initial position and the reference position of the bag-making component, including: controlling the drive adjustment component to move the bag-making component from the initial position to the trial production position and trial producing a sample bag according to the first specification parameter; obtaining the sample specification parameter of the sample bag and comparing the sample specification parameter with the first specification parameter to obtain the parameter deviation; and determining the positional deviation according to the parameter deviation.

[0008] By adopting the above solution, the deviation between the actual product and the target specifications is obtained through trial production, and the positional deviation of each bag-making component is deduced in reverse, which effectively solves the problem of insufficient precision in manual adjustment.

Furthermore, after controlling the drive adjustment component to move the bag-making component from the initial position to the first target position, the method further includes: determining the first target position as the origin of the bag-making component.

[0010] By adopting the above scheme, the method of correcting positional deviations before movement improves the positioning accuracy and stability of the bag-making components. The method of moving first and then correcting positional deviations, using the intermediate position as a buffer, facilitates real-time monitoring and adjustment, enhancing dynamic adaptability and process controllability. The method of correcting positional deviations while moving shortens the adjustment time of the bag-making components, improving production efficiency. Furthermore, by setting the first target position as the origin, a unified reference standard is established for positional adjustments in subsequent production processes, which is beneficial for improving positional control accuracy during mass production.

[0011] According to another specific embodiment of the present invention, the bag-making method of the bag-making equipment disclosed in this embodiment confirms the operating state of the drive adjustment component so that the drive adjustment component operates in a preset state, including: adjusting the output direction of the drive adjustment component according to a first target position so that the drive adjustment component operates in a target output direction; including: controlling the drive adjustment component to drive the bag-making component to move in the current output direction; determining whether the moving direction of the bag-making component is closer to the direction of the first target position; if so, then taking the current output direction as the target output direction; if not, then taking the direction opposite to the current output direction as the target output direction. Furthermore, the bag-making equipment also includes a sensor; when adjusting the drive adjustment component, the method further includes: verifying whether the sensor's working state is normal.

[0012] By adopting the above solution and adjusting the output direction of the drive adjustment component, the problem of reverse operation that may occur during manual adjustment is effectively solved.

[0038] As described in the background section, current bag-making equipment requires manual adjustment of the operating parameters of each bag-making component when producing packaging bags of different sizes. The main adjustment process is as follows: first, the position of each bag-making component is adjusted one by one by manually adjusting mechanical handles, bolts, and other related parts. After adjustment, trial production is conducted, and sample dimensions are measured to verify the adjustment results. If the sample dimensions do not meet the requirements, the position of the bag-making components is readjusted, and the above steps are repeated until the packaging bag dimensions meet the requirements.

[0039] This adjustment method has several problems: First, it is inefficient, requiring significant time for equipment adjustments each time a product is changed; second, adjustment accuracy is difficult to guarantee, relying entirely on the operator's experience; third, the adjustment process is cumbersome and complex, prone to human error; and finally, producing correctly sized packaging bags may require multiple trial production and adjustment processes, resulting in raw material waste and increased production costs. These problems severely restrict the production efficiency and product quality of bag-making equipment, failing to meet the modern packaging industry's demands for rapid specification changeovers and high-precision production.

[0040] To address the problems of low efficiency and poor accuracy in the manual adjustment of bag-making components during the production of packaging bags of different specifications, this application provides a bag-making method for a bag-making device and a bag-making system applicable to this method. This bag-making method can determine the target position of the bag-making components based on the specifications of the target product to be produced. Therefore, by controlling the drive adjustment components, the bag-making components can be automatically and precisely adjusted to their position, effectively solving the problems of low efficiency and poor accuracy of manual adjustment. Furthermore, in the first production cycle after the bag-making device is powered on, before producing the target product, the position of the bag-making components is controlled based on the positional deviation between the initial position and the reference position, eliminating dimensional deviations caused by mechanical errors during the installation of the bag-making device, further improving product accuracy.

[0041] The bag-making equipment provided in this application includes a frame, a bag-making component mounted on the frame, and a drive and adjustment component connected to the bag-making component. The frame is used to fix and mount the bag-making component and the drive and adjustment component. The bag-making component is used to manufacture packaging bags, including but not limited to components for feeding paper material, components for forming the bag body, components for sealing the bag body, and components for packaging the finished bags. The drive and adjustment component is used to precisely control the positional movement of the bag-making component, and can specifically be a servo motor, cylinder, hydraulic cylinder, etc. In a preferred embodiment, the drive and adjustment component is a servo motor. Servo motors have high positioning accuracy and response speed, and can simultaneously control the speed, position, and thrust of the motor, providing high control accuracy and efficiency for the bag-making component. The output end of the drive and adjustment component can be connected to the bag-making component via a gear rack, transmission belt, or other transmission component, thereby enabling the drive component to drive the transmission component and thus move the bag-making component. The specific structure of the bag-making equipment will be described in detail later.

[0042] The bag-making method and system provided in this application will be described next.

[0043] Example 1:

[0044] This embodiment provides a bag-making method using a bag-making device, referencing... Figure 1 This includes the following steps:

[0045] The bag-making equipment is powered on, and the bag-making components move to their initial positions.

[0046] Obtain the first specification parameters of the first target product corresponding to the initial production cycle, determine the first target position of the bag-making component based on the first specification parameters, and determine the position deviation between the initial position and the reference position of the bag-making component; confirm the operating status of the drive adjustment component so that the drive adjustment component operates in a preset state; control the drive adjustment component to move the bag-making component from the initial position to the first target position based on the first target position and the position deviation.

[0047] Obtain the second specification parameters of the second target product corresponding to the current production cycle, and control the drive adjustment component to move the bag making component from the first target position to the second target position according to the second specification parameters.

[0048] Specifically, the initial position can be the default position after the equipment is started. This default position can be set according to actual needs; it can be the position of each bag-making component when the equipment was last powered on and off, or it can be the zero-point position of each bag-making component. The reference position can be the standard position set at the factory. Position deviation can be determined by instrument measurement, sensor measurement, or comparison parameters after trial production of sample bags. The first and second specification parameters can include dimensional information such as the length, width, and height of the packaging bag. The preset state of the drive adjustment component can include the setting of parameters such as output direction, speed, and acceleration. The operating status of the drive adjustment component can be confirmed by the user's visual observation or by displaying the operating status as text on the bag-making equipment's display. As a preferred embodiment, the drive adjustment component can adopt a closed-loop control method, adjusting its position in real time through feedback signals from sensors or manual input by the operator, thereby improving positioning accuracy.

[0049] The target location is determined based on specifications. Specifically, this can be achieved by pre-storing a mapping table of packaging bag dimensions and the coordinates of each bag-making component. Once the specifications are obtained, the corresponding target location is retrieved by looking up the table. Alternatively, a function expression of packaging bag dimensions versus bag-making component coordinates can be fitted using a large amount of packaging bag size and corresponding component coordinate data. Once the specifications are obtained, they are input into the function expression to calculate the corresponding target location.

[0050] To control the drive adjustment component to move the bag-making component to the target position, it is necessary to pre-store the mapping relationship expression between the movement amount of the bag-making component and the parameters of the drive adjustment component. After the target position is determined, the movement amount of the bag-making component is further calculated based on the target position, and the target parameters of the drive adjustment component are determined according to the mapping relationship expression. The output of the drive adjustment component is then controlled according to the target parameters of the drive adjustment component.

[0051] Furthermore, during the initial production cycle, when the control drive adjustment component moves the bag-making component to the first target position, the influence of position deviation is taken into account. This eliminates mechanical assembly errors during the process of the bag-making component moving to the first target position. During the current production cycle, the bag-making component starts moving from the first target position, avoiding the accumulation of errors and further improving the control accuracy of the bag-making component. Moreover, there is no need to set a separate adjustment step to eliminate mechanical errors, thus improving the control efficiency of the bag-making component.

[0052] Furthermore, before the drive adjustment component moves the bag-making component to the first target position, the operating status of the drive adjustment component is confirmed to ensure that the drive adjustment component can operate in the preset state. This avoids the bag-making component moving in the opposite direction or at a lower operating speed due to an incorrect operating status of the drive adjustment component, which would reduce production efficiency.

[0053] With this process, the drive adjustment component can precisely control the bag-making component to move to the target position based on the acquired product specification parameters and positional deviation information. When producing products of different specifications, only the new specification parameters need to be input to automatically complete the position adjustment of the bag-making component without manual intervention. This achieves automation and precision in the position adjustment of the bag-making component, improving production efficiency and product consistency. Furthermore, during the initial production cycle, the drive adjustment component is controlled based on the positional deviation between the initial position and the reference position of the bag-making component and the first target position. This allows the mechanical errors during equipment installation to be eliminated during the movement of the bag-making component to the first target position. Moreover, by confirming the operating status of the drive adjustment component, the efficiency and accuracy of the bag-making component moving to the target position are improved.

[0054] Furthermore, this embodiment provides two methods for determining positional deviation, including the measurement method and the sample bag comparison method.

[0055] The measurement method includes: defining the reference position of the bag-making component according to the standard installation position of the bag-making equipment when it leaves the factory; directly measuring the distance difference between the initial position and the reference position of the bag-making component using a measuring tool, and using the distance difference as the position deviation.

[0056] Specifically, the measuring tools can be precision measuring devices such as laser rangefinders, vernier calipers, or optical sensors. For example, laser rangefinders calculate distance differences by emitting laser beams and receiving reflected signals, vernier calipers acquire distance differences through mechanical contact measurement, and optical sensors determine positional deviations through image recognition technology. This measurement method uses a standard installation position as a fixed reference point. By defining the reference position and directly measuring the distance, it achieves precise quantification of positional deviations. Furthermore, the combination of factory-preset references and precision measuring tools eliminates human error, thus providing a unified positional basis for subsequent position adjustments. Direct measurement quantifies distance data, improving the accuracy of positional deviations and consequently enhancing the positional control precision of the bag-making components.

[0057] The sample bag comparison method includes: controlling the drive adjustment component to move the bag making component from the initial position to the trial production position and producing a sample bag according to the first specification parameter; obtaining the sample specification parameter of the sample bag and comparing the sample specification parameter with the first specification parameter to obtain the parameter deviation; and determining the position deviation based on the parameter deviation.

[0058] Specifically, the trial production location can be set to the theoretical location corresponding to the first specification parameter, or it can be set to an estimated location corrected based on historical data. The sample specification parameters of the sample bags can be obtained using optical measuring instruments, contact measuring instruments, or manual measuring tools. Parameter deviations can be calculated using absolute value comparison or percentage comparison methods. As a preferred implementation, the number of trial production sample bags can be set to 3-5, and the average value of the sample specification parameters is compared to improve measurement accuracy. The sample bag comparison method obtains the deviation between the actual product and the target specification through trial production, and then deduces the positional deviation of each bag-making component, effectively solving the problem of insufficient precision in manual adjustment.

[0059] Furthermore, in this bag-making method, after determining the positional deviation, it can be eliminated when the bag-making component moves to the first target position. Specifically, the control drive adjustment component moves the bag-making component from the initial position to the first target position in the following three ways:

[0060] The first method involves controlling the drive adjustment component based on the position deviation to move the bag-making component from its initial position to a reference position, and then controlling the drive adjustment component based on the first specification parameters to move the bag-making component from the reference position to the first target position. This method requires correcting the position deviation before movement, which improves the positioning accuracy and stability of the bag-making component.

[0061] The second method involves controlling the drive adjustment component to move the bag-making component from the initial position to the intermediate position based on the first specification parameters. Then, based on the positional deviation, the drive adjustment component is used to move the bag-making component from the intermediate position to the first target position. This method requires moving the component first and then correcting the positional deviation, using the intermediate position as a buffer. This facilitates real-time monitoring and adjustment, enhancing dynamic adaptability and process controllability.

[0062] The third method involves controlling and adjusting the bag-making component based on the first specification parameters and positional deviation to move the bag-making component directly from its initial position to the first target position. This method corrects positional deviations while moving the component, shortening the adjustment time and improving production efficiency.

[0063] Assume the reference position of a bag-making component is (0,0,0), and the initial position is (2,0,0). When producing the target product, the bag-making component theoretically needs to move from 0mm to 10mm, with a measured positional deviation of +2mm. In the first adjustment method, the bag-making component needs to be moved from (2,0,0) to (0,0,0) to eliminate the positional deviation, and then moved from (0,0,0) to (10,0,0). In the second adjustment method, the bag-making component needs to be moved from (0,0,0) to (12,0,0) and then from (12,0,0) to (10, 0,0) to eliminate the deviation. In the third adjustment method, the bag-making component is directly moved from (2,0,0) to (10, 0,0).

[0064] It is important to understand that the position deviation can be determined through a preset deviation conversion formula, which can convert the parameter deviation into the displacement compensation amount of the drive adjustment component.

[0065] Furthermore, in this bag-making method, after the control drive adjustment component moves the bag-making component from the initial position to the first target position, the method further includes defining the first target position as the origin of the bag-making component. This can be achieved by using a confirmation button provided by the bag-making equipment; the confirmation button is pressed after the bag-making component has fully moved to the first target position.

[0066] This process, by setting the first target position as the origin, establishes a unified reference benchmark for position adjustments in subsequent production processes, which helps improve the position control accuracy during mass production.

[0067] Furthermore, in this bag-making method, confirming the operating state of the drive adjustment component to ensure it operates in a preset state includes: adjusting the output direction of the drive adjustment component according to the first target position to ensure it operates in the target output direction. Specifically, this includes: controlling the drive adjustment component to move the bag-making component in the current output direction; and determining whether the moving direction of the bag-making component is closer to the direction of the first target position.

[0068] If so, then the current output direction will be the target output direction.

[0069] If not, then the target output direction is the direction opposite to the current output direction.

[0070] In practical implementation, the output direction of the adjustment drive adjustment component can be adjusted in the following ways: a displacement sensor is used to monitor the movement trajectory of the bag-making component in real time, and the actual movement direction is compared with the preset direction; or a photoelectric switch is used to detect the position change of the bag-making component, and the logic circuit determines whether the movement direction is correct.

[0071] This method effectively solves the problem of reverse operation that may occur during manual adjustment by adjusting the output direction of the drive adjustment component. The direction determination mechanism ensures that the drive adjustment component always operates in the correct direction, avoiding positioning deviations caused by incorrect orientation.

[0072] Furthermore, in this bag-making method, the bag-making equipment also includes sensors. The sensors on the bag-making equipment are used for position detection of the bag-making components or the bag body, etc. Moreover, when adjusting the drive adjustment components, the method also includes verifying whether the sensor's working status is normal.

[0073] Specifically, when verifying the sensor's operational status, a standard test signal can be input to the sensor to check if its output signal meets expectations; alternatively, it can be done through visual observation and experience-based judgment. This step, by verifying the sensor's status while adjusting the drive adjustment component, allows for timely detection of detection anomalies, ensuring the reliability of position control. Controlling the drive adjustment component to move the bag-making component only after confirming the status of both the sensor and the drive adjustment component ensures that the drive adjustment component operates in the correct direction and the sensor operates under standard working conditions, avoiding mechanical errors caused by incorrect drive adjustment component orientation or sensor malfunction.

[0074] Furthermore, in this bag-making method, after the bag-making component moves from the first target position to the second target position, the method further includes: obtaining the third specification parameters of the third target product corresponding to the next production cycle, and controlling the drive adjustment component to move the bag-making component from the second target position to the third target position according to the third specification parameters.

[0075] Specifically, the acquisition of the third specification parameter can be achieved through external input devices, such as a touch screen or a host computer. When producing the third target product corresponding to the next production cycle, the bag-making component is controlled to move directly from the second target position to the third target position without having to return to the initial position before moving again, thus improving the operating efficiency of the bag-making component.

[0076] Next, refer to Figure 2 For example, describe a bag-making device. Figure 2The bag-making equipment shown includes a frame 1, and bag-making components and drive adjustment components 2 mounted on the frame 1. The bag-making equipment includes a feeding station 3 and a forming station 4 sequentially arranged along the length (X) of the frame 1. Correspondingly, the bag-making components include a sheet material conveying component at the feeding station 3, and a forming mold, a bag-body limiting component, and a bag-body sealing component at the forming station 4. The sheet material conveying component is used to convey sheet material and can employ a servo motor-driven conveyor belt mechanism. Preferably, at least one pair of conveyor belts are arranged opposite each other along the width direction of the frame 1. Each conveyor belt is controlled by a servo motor to move along the width direction, enabling the conveying of sheet material of different sizes. The forming mold can move along the height (Z) direction of the frame 1, causing the sheet material to wrap around the outside of the forming mold to form a three-dimensional bag structure. The forming mold includes a front width adjustment plate and a side width adjustment plate arranged opposite each other. The four adjustment plates form a complete rectangular structure, and each plate is controlled by a corresponding servo motor. When the packaging bag specifications change, the servo motor of each adjusting plate will drive the corresponding adjusting plate to a position corresponding to the front width and side width of the packaging bag. The bag body limiting component can use structures such as protrusions or baffles, fixed at the position corresponding to the front of the forming mold and the front of the bag body, used to limit the movement of the front of the bag body relative to the forming mold in the height direction. The bag body limiting component is connected to the servo motor, and when the packaging bag specifications change, the servo motor can drive the bag body limiting component to the corresponding position. The bag sealing component can use a heat sealing mechanism or a glue gun, and the movement range between the sealing blade or glue gun can be adjusted by the servo motor to adapt to different bag types.

[0077] Furthermore, in this bag-making method, the first specification parameters include the front width, side width, and bag height of the first target product; the second specification parameters include the front width, side width, and bag height of the second target product; and the third specification parameters include the front width, side width, and bag height of the third target product.

[0078] In the initial production cycle, controlling the drive adjustment components to move the bag-making components from their initial positions to their first target positions based on the first target positions and position deviations includes: controlling the corresponding drive adjustment components to move the sheet material conveying components, forming molds, bag body limiting components, and bag body sealing components from their respective initial positions to their respective first target positions based on the position deviations of the sheet material conveying components, forming molds, bag body limiting components, and bag body sealing components, as well as the front width, side width, and bag height of the first target product. Furthermore, after moving to the first target positions, the process further includes: the bag-making equipment producing the first target product according to the first target positions.

[0079] In the current production cycle, controlling the drive adjustment components to move the bag-making components from the first target position to the second target position according to the second specification parameters includes: controlling the drive adjustment components corresponding to the sheet material conveying component, forming mold, bag body limiting component, and bag body sealing component to move these components from their respective first target positions to the second target positions according to the front width, side width, and bag height of the second target product. Furthermore, after moving to the second target position, the process also includes: the bag-making equipment producing the second target product according to the second target position.

[0080] In the next production cycle, controlling the drive adjustment components to move the bag-making components from the second target position to the third target position according to the third specification parameters includes: controlling the drive adjustment components corresponding to the sheet material conveying component, forming mold, bag body limiting component, and bag body sealing component to move these components from their respective second target positions to the third target positions according to the front width, side width, and bag height of the third target product. Furthermore, after moving to the third target position, the bag-making equipment also produces the third target product according to the third target position.

[0081] With these steps, the bag-making component includes multiple actuators at the feeding station 3 and the forming station 4. Each actuator has an independent drive adjustment component, enabling multi-dimensional precise adjustment of each bag-making component. Specifically, during the initial production cycle, the drive adjustment components are comprehensively controlled based on product specification parameters and positional deviations, ensuring positioning accuracy when switching between different product specifications. In other words, when producing target products of different specifications, the bag-making equipment can automatically complete the coordinated positioning of all bag-making components without manual intervention; and the position adjustment process of the bag-making components eliminates positional deviations, avoiding errors caused by positional deviations. Furthermore, the bag-making components at each station can be adjusted independently, allowing for precise forming even of complex bag shapes.

[0082] Further, refer to Figure 2The bag-making equipment also includes a bag-removing component located at forming station 4. The bag-removing component is a part in forming station 4 used to remove the formed packaging bag from the mold. Specifically, it can include belts or suction cups located on both sides of the forming mold and the front of the bag. A servo motor controls the belts to rotate in opposite directions, causing the bag to detach from the forming mold under friction; or the suction cups hold the bag and the servo motor moves the bag to detach it from the forming mold. When the bag-removing component moves to the first or second target position, its relative position to the forming mold must be adapted to the bag size of the target product in the current production cycle to ensure the reliability of the bag-removing action. By adding a bag-removing component that can automatically adjust its position, the bag-making equipment can adapt to the production needs of products with different specifications.

[0083] Furthermore, during the initial production cycle, when the sheet material conveying component, forming mold, bag body limiting component, and bag body sealing component move from their respective initial positions to their respective first target positions, the process also includes: the bag-removing component moving from its corresponding initial position to its corresponding first target position. Additionally, after the bag-making equipment produces the first target product according to the first target position, the process also includes: the bag-removing component moving from its first target position to its initial position.

[0084] In the current production cycle, when the sheet material conveying component, forming mold, and bag limiting component move from their respective first target positions to second target positions, the process also includes: controlling the drive adjustment component corresponding to the bag-unloading component to move the bag-unloading component from its initial position to the second target position based on the front width, side width, and bag height of the second target product. Furthermore, after the bag-making equipment produces the second target product according to the second target position, the process also includes: the bag-unloading component moving from the second target position to its initial position.

[0085] In the next production cycle, when the sheet material conveying component, forming mold, bag limiting component, and bag sealing component move from their respective second target positions to the third target positions, the process also includes: controlling the drive adjustment component corresponding to the bag removal component to move the bag removal component from its initial position to the third target position according to the front width, side width, and bag height of the third target product; after the bag making equipment produces the third target product according to the third target position, the process also includes: the bag removal component moving from the third target position to its initial position.

[0086] In other words, in this bag-making method, the bag-unloading component must return to its initial position after completing the unloading action. This design prevents the unloading component from interfering with the bag-making process. Furthermore, in bag-making equipment, the positioning of the unloading component is generally achieved through sensors. Moving the unloading component to its initial position after unloading avoids inaccurate positioning caused by accumulated mechanical errors in the sensors. With this step, the position adjustment of the unloading component is synchronized with other bag-making components and controlled by the drive adjustment component, thus ensuring the accuracy and reliability of the unloading action. This not only avoids the tedious operation of manual unloading or manual adjustment of the unloading component's position, improving the equipment's adaptability to different product specifications, but also ensures the stability of the unloading action by automatically resetting the unloading component after each production cycle, preparing for the next production cycle. This further improves the production efficiency of the bag-making equipment.

[0087] Further, refer to Figure 2 The bag-making equipment also includes a bag opening folding station 5, and the bag-making components include a bag opening support component located at the bag opening folding station 5. At the bag opening folding station 5, the sheet material can be folded inward on both sides along its length to form a bag opening fold. The bag opening support component is a support plate that is movable along the length of the sheet material and is located on the inner side of the corresponding edge of the bag opening folding station 5 in the width direction of the frame 1. It is used to provide stable support for the sheet material along its width direction, so that the fold can be stably folded along the crease line when the packaging bag is folded. The position of the support plate can be adjusted by a servo motor. The support plate can be connected to a linear guide or a rotating mechanism to achieve position adjustment. By adding the bag opening folding station 5 and the corresponding bag opening support component, precise control of the fold width of the packaging bag is achieved.

[0088] Furthermore, in this bag-making method, the first specification parameter also includes the folded edge width of the first target product; the second specification parameter also includes the folded edge width of the second target product; and the third specification parameter also includes the folded edge width of the third target product.

[0089] Furthermore, in the initial production cycle, the method of controlling the drive adjustment component to move the bag-making component from the initial position to the first target position based on the first target position and the position deviation also includes: controlling the corresponding drive adjustment component to move the bag-mouth support component from the corresponding initial position to the first target position based on the position deviation of the bag mouth support component and the folded edge width of the first target product.

[0090] In the current production cycle, the control of the drive adjustment component to move the bag making component from the first target position to the second target position according to the second specification parameters also includes: controlling the drive adjustment component corresponding to the bag opening support component to move the bag opening support component from the corresponding first target position to the corresponding second target position according to the folding width of the second target product.

[0091] In the next production cycle, the drive adjustment component is controlled according to the third specification parameter to move the bag making component from the second target position to the third target position. The control also includes: according to the folding width of the third target product, the drive adjustment component corresponding to the bag opening support component is controlled to move the bag opening support component from the corresponding second target position to the corresponding third target position.

[0092] With this process, the drive adjustment component can automatically adjust the position of the bag opening support component according to the product specifications, avoiding the inefficiency and lack of precision caused by manual adjustment. The position adjustment of the bag opening support component works in conjunction with other components of the bag-making equipment to ensure the synchronization and consistency of the folding process with other bag-making processes. During production, position deviation compensation and target position calculation improve the positioning accuracy of the folding process, enabling the bag-making equipment and method to adapt to the rapid switching production needs of different product specifications.

[0093] Further, refer to Figure 2 The bag-making equipment also includes a handle fixing station 6, and the bag-making components include a support platform and a rope-threading component located at the handle fixing station 6. The support platform is used to support and position the sheet material, and the rope-threading component is used to complete the handle rope-threading process. It includes a gripping component and a fixing component, each connected to a corresponding servo motor to complete the handle rope-threading operation at a predetermined position. The gripping component can move along the height of the frame 1. The sheet material has a handle opening. The gripping component grabs both ends of the handle from below the handle opening to above the opening and releases them. The fixing component reciprocates on the support platform using a roller to fix the handle. By setting the handle fixing station 6, the produced product has a handle, resulting in better performance.

[0094] Furthermore, in this bag-making method, the first specification parameter also includes the center distance of the handle strip of the first target product; the second specification parameter also includes the center distance of the handle strip of the second target product; and the third specification parameter also includes the center distance of the handle strip of the third target product. The center distance of the handle strip refers to the center distance between the fixing points of the handles on both sides of the packaging bag, and this parameter directly affects the accuracy of the handle installation position.

[0095] In the initial production cycle, the drive adjustment component is controlled to move the bag-making component from the initial position to the first target position according to the first target position and the position deviation. It also includes: controlling the corresponding drive adjustment component to move the support platform and the rope threading component from their respective initial positions to the first target positions according to the position deviation of the support platform and the rope threading component and the center distance of the handle strip of the first target product.

[0096] In the current production cycle, the control of the drive adjustment component to move the bag making component from the first target position to the second target position according to the second specification parameters also includes: controlling the corresponding drive adjustment component to move the support table and the rope threading component from their respective first target positions to the second target positions according to the center distance of the handle strip of the second target product.

[0097] In the next production cycle, the drive adjustment component is controlled according to the third specification parameter to move the bag making component from the second target position to the third target position. It also includes: according to the center distance of the handle strip of the third target product, the corresponding drive adjustment component is controlled to move the support table and the rope threading component from their respective second target positions to the third target positions.

[0098] Further, refer to Figure 2 The bag-making equipment also includes a card placement station 7, and the bag-making components also include a mounting base disposed at the card placement station 7. The card placement station 7 is located between the feeding station 3 and the handle fixing station 6, and it can place the card between the folded edge and the bag body, making the installation stability of the handle better. Specifically, the mounting base is provided with a card gripping component and a card feeding component. The card feeding component transports the card to the opening area of ​​the card opening on the sheet material, and the card gripping component grips the card through the card opening and moves it to place the card in a preset position.

[0099] Furthermore, in this bag-making method, during the initial production cycle, the drive adjustment component is controlled to move the bag-making component from the initial position to the first target position based on the first target position and the position deviation. The method also includes: controlling the drive adjustment component corresponding to the mounting seat to move the mounting seat from the corresponding initial position to the first target position based on the position deviation of the mounting seat and the center distance of the handle strip of the first target product.

[0100] In the current production cycle, the control of the drive adjustment component to move the bag making component from the first target position to the second target position according to the second specification parameters also includes: controlling the drive adjustment component corresponding to the mounting seat to move the mounting seat from the corresponding first target position to the corresponding second target position according to the center distance of the handle strip of the second target product.

[0101] In the next production cycle, the drive adjustment component is controlled according to the third specification parameter to move the bag making component from the second target position to the third target position. It also includes: controlling the drive adjustment component corresponding to the mounting seat according to the center distance of the strip of the third target product to move the mounting seat from the corresponding second target position to the corresponding third target position.

[0102] With these steps, the synchronous movement of the support platform and the rope threading component ensures the matching of the rope threading position of the handle with the position of the bag body, while the independent adjustment of the mounting base ensures the accuracy of the head clip installation position.

[0103] Furthermore, in this bag-making method, after obtaining the first specification parameter, the second specification parameter, and the third specification parameter, each step includes: obtaining the mold specification adaptation range of the forming mold, and determining whether the first specification parameter, the second specification parameter, and the third specification parameter exceed the mold specification adaptation range.

[0104] If so, replace the molding die.

[0105] If not, the drive adjustment component controls the current movement of the molding die.

[0106] Specifically, the mold adaptation range of a molding die refers to the range between the minimum and maximum values ​​that the mold can move under the drive and adjustment components. For example, the mold adaptation range of a certain molding die is 100mm to 500mm, but if the corresponding specification parameter of the packaging bag is 600mm, it exceeds the adaptation range of the molding die, and the molding die needs to be replaced.

[0107] After obtaining the first specification parameter, the second specification parameter, and the third specification parameter, the method further includes: obtaining the support specification adaptation range of the bag opening support component, and determining whether the first specification parameter, the second specification parameter, and the third specification parameter exceed the support specification adaptation range.

[0108] If so, replace the bag opening support component.

[0109] If not, the drive adjustment component controls the movement of the current bag opening support component.

[0110] Specifically, the support specification adaptation range refers to the range between the minimum and maximum values ​​that the bag opening support component can move under the drive and adjustment of the component. For example, if a certain support component is adapted to a range of 300mm to 400mm, and the corresponding specification parameter of the packaging bag is 800mm, it exceeds the adaptation range of the bag opening support component, and the bag opening support component needs to be replaced.

[0111] With these steps, the mechanism for judging the compatibility range of mold specifications and support specifications ensures that the equipment can adapt to the needs of products with different specifications, thus avoiding packaging bag production errors caused by hardware incompatibility.

[0112] It should be noted that the bag-making method provided in this application is not limited to the bag-making equipment provided in this embodiment, but is also applicable to other bag-making equipment.

[0113] Next, the bag-making method provided in this embodiment will be described in general, taking the following examples: the first target product has a front width, side width, and bag height of 40*10cm*30cm, a folded edge width of 2cm, and a handle center distance of 10cm; the second target product has a front width, side width, and bag height of 20*5cm*20cm, a folded edge width of 1cm, and a handle center distance of 3cm; and the third target product has a front width, side width, and bag height of 80*10cm*50cm, a folded edge width of 2cm, and a handle center distance of 20cm. Furthermore, the mold specifications of the current forming mold are adapted to a range of (10*5cm*10cm) to (50*20cm*100cm), and the support specifications of the bag opening support component are adapted to a bag height of 10cm to 50cm.

[0114] First, the equipment is powered on, and all bag-making components remain in their current positions.

[0115] Next, the front width, side width, bag height, folded edge width, and handle center distance of the first target product are input. Based on these parameters, the target positions of each bag-making component are determined, and the first target positions of the corresponding drive adjustment components are determined based on the target positions of the bag-making components. It is then determined whether the specifications of the first target product exceed the mold specification adaptation range of the forming mold and the support specification adaptation range of the bag opening support component. If determined, no replacement of the mold or bag opening support component is required.

[0116] Next, the positional deviation of each bag-making component from its corresponding reference position is measured using a vernier caliper. The movement of the bag-making component is controlled by jogging to determine whether the output direction of the drive adjustment component is close to the target position. When the output direction is opposite to the target direction, the output direction of the drive adjustment component is adjusted so that the drive adjustment component moves in the target direction.

[0117] Next, based on the first target position and the position deviation, the control drive adjustment component moves the bag-making component from the initial position to the first target position, and the initial production cycle begins.

[0118] After the first target product is produced, input the front width, side width, bag height, folded edge width, and handle center distance of the second target product. Based on these parameters, determine the target positions of each bag-making component, and further determine the second target positions of each drive adjustment component corresponding to each bag-making component. Determine whether the specifications of the second target product exceed the mold specification adaptation range of the forming mold and the support specification adaptation range of the bag opening support component. If determined correctly, no replacement of the mold or bag opening support component is required.

[0119] Next, the bag-making component is moved from the first target position to the second target position by the control and drive adjustment component according to the second target position, and production of the current production cycle begins.

[0120] After the production of the second target product is completed, the front width, side width, bag height, folded edge width, and handle center distance of the third target product are input. Based on these parameters, the target positions of each bag-making component are determined, and the third target positions of each drive adjustment component corresponding to each bag-making component are further determined. It is then determined whether the specifications of the third target product exceed the mold specification adaptation range of the forming mold and the support specification adaptation range of the bag opening support component. If determined, the forming mold needs to be replaced.

[0121] After the molding die is changed, the control drive adjustment component is used to move the bag making component from the second target position to the third target position according to the third target position, and the production of the next production cycle begins.

[0122] Example 2:

[0123] Based on the above-described bag-making method, this embodiment provides a bag-making system for implementing the bag-making method provided in Embodiment 1.

[0124] The bag-making system includes a bag-making device and a control unit. The control unit is connected to both an external input device and the drive adjustment component of the bag-making device. Specifically, the control unit receives power-on information from the external input device and controls the bag-making component to move to its initial position based on this information. The control unit also receives the specification parameters of the target product from the external input device and controls the drive adjustment component to move the bag-making component from its current position to the target position based on these parameters.

[0125] Specifically, the control device includes, but is not limited to, programmable logic controllers, distributed control systems, numerical control systems, and other devices capable of performing logical operations and outputting instructions. External input devices can be displays directly connected to the bag-making system via wiring harnesses, or Bluetooth-connected mobile phones, tablets, and other devices capable of inputting instruction parameters.

[0126] The bag-making system provided in this embodiment can control the position and motion parameters of the bag-making components through a drive adjustment component. This drive adjustment component moves the bag-making components based on the specifications of the target product, resulting in higher adjustment accuracy of the bag-making components. This ensures that the size of the produced packaging bags is consistent with the target specifications, and that the production process has a higher degree of automation and precision.
