Description

Technical Field

[0001] This invention relates to the field of packaging bag manufacturing technology, and in particular to a bag-making method and system for bag-making equipment. Background Technology

[0002] Bag-making equipment is a key piece of equipment for manufacturing packaging bags. It uses a traction mechanism to transport raw materials to sequentially complete steps such as horizontal sealing, side sealing, and cutting, ultimately producing packaging bags that meet the required specifications. The positions of each bag-making component on the equipment (such as the folding mechanism, horizontal sealing mechanism, side sealing mechanism, and cutting mechanism) must be strictly adapted to the size specifications of the target packaging bag to ensure consistent bag dimensions. However, the demand for diverse, small-batch, and customized packaging bags is gradually increasing. If a new size packaging bag needs to be manufactured using bag-making equipment, the positions of the various bag-making components on the equipment must be readjusted.

[0003] Currently, the adjustment of the bag-making components mainly relies on manual labor. However, manual adjustment is highly dependent on the operator's experience and the complexity of the equipment, resulting in extremely low efficiency. Furthermore, dimensional deviations are prone to occur during adjustment, leading to poor accuracy.

[0004] Therefore, when dealing with the production of packaging bags of different specifications, existing bag-making equipment requires manual adjustment of the position of the bag-making components, resulting in low efficiency and poor precision. Summary of the Invention

[0067] 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.

[0068] This adjustment method has many problems: First, it is inefficient, requiring a significant amount of time for equipment adjustments each time a product is switched; 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, trial production results 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 changes and high-precision production.

[0069] 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 convert the acquired current bag type parameters into the current bag type parameters required for producing the current target product, and determine the current target state that the bag-making components need to achieve to produce the current target product based on the current bag type parameters. Then, a control state adjustment component drives the bag-making components to switch from the current working state to the current target state, thereby automatically controlling the bag-making components to adjust their working state, effectively solving the problems of low efficiency and poor accuracy associated with manual adjustment.

[0070] refer to Figure 1 Taking the bag-making process of a paper bag machine as an example, the bag-making equipment includes a frame 1, a bag-making component mounted on the frame 1, and a status adjustment component connected to the bag-making component. The frame 1 is used to support and fix the bag-making component. (Reference) Figure 1Raw materials are fed from left to right to produce finished paper bags. During the paper bag production process, the paper material fed towards the paper bag machine first passes through bag forming area A for tube forming, side gluing, and side sealing. Then it is conveyed to bottom forming area B for cutting, bottom opening, bottom gluing, and bottom closing. Finally, it is conveyed to forming area C for finished product processing. The bag-making components include... Figure 1 The width adjustment component 2 shown is, in fact, not limited to, the bag-making components. It may also include, for example, a limiting paper stop bar related to the tube forming operation, a surface width adjustment mechanism, a side width adjustment mechanism, etc.; a glue applicator roller and a creasing roller related to side gluing; a pressure roller related to side pressing; a cutter related to cutting; a clamp and side clamp related to bottom opening; a glue applicator roller related to bottom gluing; and a cutting tool related to bottom closing, etc. The state adjustment components include... Figure 1 The diagram shows a second movable support 3 connected to the width adjustment component 2 and used to move the width adjustment component 2. The state adjustment component is not limited to this; it may also include, for example, supports that move the face width adjustment mechanism and the side width adjustment mechanism, rollers that rotate the coating roller, the creasing roller, and the pressing roller, a rotary cam that rotates the cutter, supports that move the clamps, side clamps, and inserts, etc. The state adjustment component is connected to the drive component 4 so that the drive component 4 can change the position or state of the state adjustment component, thereby causing a change in the position or state of the bag-making component to adapt to the production of paper bags of different sizes. The drive component 4 may be directly connected to the state adjustment component to drive a change in the state of the state adjustment component, or it may drive other intermediate mechanisms to achieve a change in the position of the state adjustment component, such as driving a gear to drive a rack to move the support, or driving a lead screw to move the support. The drive component 4 may be implemented using a device capable of providing driving force, such as a servo motor, a cylinder, or a hydraulic cylinder.

[0071] This application uses the paper bag making process of a paper bag machine as an example for illustration only. In fact, bag making equipment is not limited to the paper bag machine exemplified in this application, but can also be other types of bag making equipment. The difference between other types of bag making equipment and paper bag machines lies only in the slight differences in raw materials and the structure of each processing area. For example, replacing paper with non-woven fabric or plastic, or adding a steering and bottom closing mechanism downstream of the large drum in the bag bottom forming area B.

[0072] Next, the bag-making method and bag-making system provided in this embodiment will be described.

[0073] Example 1:

[0074] refer to Figure 2 The bag-making method of the bag-making equipment provided in this embodiment includes the following steps:

[0075] Obtain the current bag type parameters of the current target product corresponding to the current bag making cycle, and determine the current specification parameters of the bag making equipment corresponding to the current target product based on the current bag type parameters;

[0076] The current target state of the bag-making component is determined based on the current specifications and parameters, and the state adjustment component is controlled to switch the bag-making component from the current working state to the current target state.

[0077] Specifically, the current bag-making cycle refers to the production cycle of the current target product; the current bag type parameters refer to parameters related to the size of the current target product; the current specification parameters refer to parameters used to adjust the state of the bag-making components; the current target state refers to the state that the bag-making components need to achieve when producing the target product; and the current working state refers to the current real-time state of the bag-making components. Taking a target product (hereinafter referred to as Type 1 bag) with a height of 300mm, a width of 200mm, and a bottom width of 100mm as an example, the current bag-making cycle is the production cycle of Type 1 bag. The current bag type parameters are related to the height, width, or bottom width of Type 1 bag, such as the side thickness, front width, and front height in the unfolded state, or the length and width in the folded state. The current bag type parameters can be obtained through image recognition, i.e., by acquiring an image of Type 1 bag and determining the current bag type parameters through image recognition and analysis. Alternatively, they can be obtained through manual input, such as the customer directly providing the required packaging bag size parameters. Current specifications, such as width, have a preset mapping relationship with the current bag type parameters. This mapping relationship can be obtained by looking up a table or by calculation. For example, if the width is specified as the front width in the unfolded state, then the width of a bag type can be determined to be 300mm. Determining the working state of the bag-making component includes, but is not limited to, physical parameters such as position, speed, and pressure. The current target state can be, for example, the position of the bag-making component, and there is also a preset mapping relationship between the current target state and the current specifications. This mapping relationship can be obtained by looking up a table or by calculation. For example, if the width is specified as twice the horizontal coordinate of the width adjustment mechanism, then the current target state of the width adjustment mechanism when producing a bag type should be at the coordinate position (150, 0, 0). When the state adjustment component drives the bag-making component to switch states, open-loop control, closed-loop control, or a combination of open-loop and closed-loop control can be used.

[0078] This method involves acquiring current bag type parameters and converting them into current specification parameters. The current target state of the bag-making component is then determined based on these parameters, allowing for automatic adjustment of the component's working state. This effectively solves the problems of low efficiency and poor accuracy associated with manual adjustment. Specifically, the state adjustment component precisely controls the position and motion parameters of the bag-making component, ensuring that the produced packaging bag size matches the target specification. Compared to manual adjustment, this method improves the automation and accuracy of equipment adjustment, and shortens the time required for changing specifications on the bag-making equipment.

[0079] Furthermore, the current bag type parameters include bag width and bag thickness; the current specification parameters include front width and bottom width; the bag-making components include a width adjustment assembly. (Reference) Figure 3 The bag width refers to the width x of the front of the bag when it is unfolded, and the bag thickness refers to the width y of the side of the bag when it is unfolded. The face width refers to the distance between the two sides of the bag, and the bottom width refers to the distance between the two faces of the bag. In the mapping relationship between the current bag type parameters and the current specification parameters provided in this embodiment, the bag width is equal to the face width, and the bag thickness is equal to the bottom width.

[0080] Furthermore, based on the current bag type parameters, the current specification parameters of the bag-making equipment corresponding to the current target product are determined, including:

[0081] The width of the bag is determined based on the width of the bag body of the current target product, and the bottom width is determined based on the thickness of the bag body of the current target product.

[0082] Furthermore, based on the current specification parameters, the current target state of the bag-making component is determined, and the state adjustment component is controlled to switch the bag-making component from the current working state to the current target state, including:

[0083] The current target position of the width adjustment component is determined based on the front width and bottom width, and the state adjustment component is controlled to move the width adjustment component from the current working position to the current target position.

[0084] Further, refer to Figure 4The width adjustment component 2 includes a front width adjustment template 5 and a side width adjustment disc 6. The state adjustment component includes a first movable bracket (not shown in the figure) and a second movable bracket 3. The first movable bracket is fixedly connected to the front width adjustment template 5 and can reciprocate along the width direction of the target product; the second movable bracket 3 is fixedly connected to the side width adjustment disc 6 and can reciprocate along the width direction. Specifically, the front width of the bag is determined by the front width adjustment template 5, and the side width of the bag is jointly determined by the side width adjustment disc 6 and the front width adjustment template 5. The front width adjustment template 5 has a first template and a second template that can move simultaneously. When adjusting the bag width, the front width adjustment template 5 extends into the bag, and the first and second templates expand the paper material towards the outside of the bag to determine the front width of the bag. The side width adjustment disc 6 has a first disc and a second disc that can move simultaneously. The first disc and the second disc extend into the inside of the bag from two sides of the paper material, respectively, and the edge of the disc abuts against the center line of the side of the bag, thereby determining the side width of the bag. The first movable bracket and the width adjustment template 5, as well as the second movable bracket and the side width adjustment plate 6, can be fixed by screwing or welding. The first movable bracket and the second movable bracket 3 are respectively connected to the lead screw, and the lead screw is connected to the output end of the drive component 4. The drive component 4 can drive the lead screw and link the first movable bracket and the second movable bracket 3 to change position, thereby driving the side width adjustment plate 6 and the width adjustment template 5 to move.

[0085] Furthermore, the position information of the width adjustment template 5 and the side width adjustment disc 6 can be monitored in real time by sensors to ensure adjustment accuracy. For example, photoelectric sensors or encoders can be used to detect the position of the width adjustment template 5 and the side width adjustment disc 6, and the detection results can be fed back to the control system. The control system then sends control commands to the drive component 4, which drives the first moving bracket and the second moving bracket 3 to move, thereby realizing closed-loop control to adjust the width of the bag.

[0086] This method automates the adjustment of bag-making components by directly mapping bag width and thickness to front and bottom widths, and then precisely adjusting them via a width adjustment component. In other words, by directly linking bag type parameters to specification parameters, manual calculations and multiple trial-and-error steps are avoided, thus shortening adjustment time. Simultaneously, the use of drive component 4 to drive the state adjustment component to precisely move the width adjustment component ensures adjustment accuracy and avoids dimensional deviations caused by manual operation. This method reduces manual intervention and improves adjustment efficiency and precision.

[0087] Furthermore, the current bag type parameters also include bag height, and the current specification parameters also include the cut length of the bag-making material. Among these, the bag height is... Figure 3The distance z between the bottom and top of the bag. The cutting length is the length of the paper material cut. Furthermore, the bag-making component also includes a cutter assembly and a feed roller located upstream of the cutter assembly. Both the feed roller and the cutter assembly are located at... Figure 1 The bottom forming area B of the bag is shown. A feed roller is used to feed the paper material, and a cutter assembly is used to cut the paper material. More specifically, the cutter assembly includes a rotary cam and a cutter body, the cutter body being detachably fixed to the outer periphery of the rotary cam. One rotation of the rotary cam drives the cutter body to complete one cut. The state adjustment component includes a first rotating shaft coaxially fixedly connected to the rotary cam and a second rotating shaft coaxially fixedly connected to the feed roller. In a preferred embodiment, the output ends of the first and second rotating shafts can be connected to a drive component 4, which drives them to rotate, thereby driving the feed roller and the rotary cam to rotate.

[0088] Furthermore, determining the current specification parameters of the bag-making equipment corresponding to the current target product based on the current bag type parameters also includes:

[0089] The cutting length input for the bag-making equipment when producing the current target product is determined based on the bag height and bag thickness of the current target product.

[0090] Furthermore, based on the current specification parameters, the current target state of the bag-making component is determined, and the state adjustment component is controlled to switch the bag-making component from the current working state to the current target state, including:

[0091] The current target speed of the cutter assembly and / or feed roller is determined based on the cutting length, and the state adjustment component is controlled to drive the cutter assembly and / or feed roller to adjust the speed from the current operating speed to the current target speed.

[0092] Specifically, in this embodiment, when the cutting length changes, the rotational speeds of both the cutter assembly and the feed roller change. For example, when the cutting length decreases, the cutter assembly's change from its current operating speed to the current target speed is an acceleration process, while the feed roller's change from its current operating speed to the current target speed is a deceleration process. By simultaneously controlling both the cutter assembly and the feed roller, the target speed can be reached quickly. In other alternative embodiments, only the rotational speed of the cutter assembly or only the rotational speed of the feed roller can be changed to reduce the number of drive components 4 and related state adjustment components, thereby reducing energy consumption.

[0093] Furthermore, the cutting length is calculated according to the following formula:

[0094]

[0095] in, To cut the long, The height of the bag. For bag thickness, The adjustment coefficient is in the range [0.05, 0.2]. It is directly proportional to the bag thickness. Specifically, the adjustment coefficient... The value of can be obtained by fitting experimental data, for example, when the bag thickness is... When increasing, The cutting length increases linearly, and can be determined using a lookup table or interpolation method. Furthermore, the formula for calculating the cutting length comprehensively considers the bag's height, thickness, and dynamic compensation factors, ensuring the accuracy of the cutting position.

[0096] Furthermore, before determining the current target state of the bag-making component based on the current specification parameters, the process also includes:

[0097] Determine whether the width of the current target product exceeds the width adjustment range of the width adjustment template;

[0098] If so, replace the width adjustment template and adjust it accordingly;

[0099] If not, continue to determine whether the width of the current target product exceeds the width adjustment range of the width adjustment template.

[0100] Specifically, the first template and the second template themselves have a certain width and can move along... Figure 4 The frame moves back and forth in the width direction (i.e., the width direction of the bag). Due to the structural limitations of the width adjustment template 5, the width adjustment template 5 has a width adaptation range, i.e., the width adjustment range. The maximum width threshold is the width at which the distance between the first and second templates is greatest, and the minimum width is the width at which the distance between the first and second templates is smallest. When the product width is less than the minimum value of this width adjustment range, inserting the template into the paper material will damage the paper material, making it impossible to generate a bag with a suitable width; when the product width is greater than the maximum value of this width adjustment range, the template cannot move to the current target position. Therefore, it is necessary to select and replace it with a new template of matching specifications. The width adjustment range can be quickly determined using a preset size comparison table, and the replacement operation can be quickly disassembled and assembled using a modular design.

[0101] Furthermore, after the template is replaced, it needs to be adjusted. This can be done by checking the parameters and retightening the screws or fasteners, or by using a support tube and screws, adjusting the screws to align the support tube lines. In a preferred embodiment, the adjustment is as follows: after replacing the template, the width adjustment template 5 is moved to the zero position where the first and second templates are close to each other, and then the first and second templates are moved to the target position according to the current target state.

[0102] Furthermore, the bag-making component also includes a bag bottom support member. The bag bottom support member is set at... Figure 1On the large drum of the bottom forming area B of the bag, there are filling plates disposed in two clamps. The state adjustment component includes brackets connected to the two clamps respectively. The brackets are connected to the drive component 4 via connecting rods. Under the drive of the drive component 4, the connecting rods drive the brackets, thereby linking the two clamps to move closer or further apart along the circumference of the large drum. When making bags with a smaller bottom width, the clamps move inward, requiring the installation of a smaller filling plate. When making bags with a larger bottom width, the clamps move outward, requiring the installation of a larger filling plate. In a preferred embodiment provided in this example, before determining the current target state of the bag-making component based on the current specification parameters, the following is also included:

[0103] Determine whether the bottom width of the current target product exceeds the bottom width adaptation range of the bag bottom support component;

[0104] If so, replace the bottom support component of the bag;

[0105] If not, then continue to determine whether the bottom width of the current target product exceeds the bottom width adaptation range of the bag bottom support component.

[0106] The bottom width adaptation range refers to the range of packaging bag bottom widths that the bottom support component can accommodate. For bag making machines, the specifications of the bottom support component are two or more fixed specifications. Therefore, determining whether the bottom width corresponding to the current target product exceeds the bottom width adaptation range of the bottom support component can be done by the operator's manual judgment of the dimensions, and the replacement of the bottom support component if the dimensions are incompatible. Of course, to improve the level of automation, the dimensions of the currently assembled bottom support component can also be input in advance, and the control device can determine whether the dimensions of the bottom support component are compatible with the dimensions of the target product, and thus determine whether it exceeds the bottom width adaptation range.

[0107] This approach effectively avoids bag-making quality problems caused by component mismatch by adding a judgment on the compatibility of bag-making components before the current target state is determined.

[0108] Furthermore, after the control state adjustment component switches the bag-making component from the current working state to the current target state, it also includes:

[0109] The bag-making equipment is tested in a jogging manner until a preset time is reached; where the preset time is the time required to produce N current target products, N is 1 to 3, and N is an integer.

[0110] Specifically, inching test runs can be performed intermittently, with each start interval being 0.5-2 seconds and a single run duration of 1-3 seconds. The preset time can be calculated based on the production rhythm of the current target product. For example, if the production cycle of a single product is 5 seconds, and N is 2, then the preset time is 10 seconds. By introducing the inching test run mechanism, after equipment specification switching, controlling the equipment to run for a period of time can detect potential installation problems, verify the stability and performance of the system, and promote the break-in and adaptation between components.

[0111] Furthermore, the bag-making method also includes:

[0112] Determine if the bag-making equipment has a fault alarm;

[0113] If so, determine whether the state adjustment component has switched to the current target state;

[0114] If the current target state is switched, troubleshooting will be performed;

[0115] If the current target state has not been switched, continue to determine whether the state adjustment component has switched to the current target state;

[0116] If not, continue to determine if the bag-making equipment has a fault alarm.

[0117] In other words, after a fault alarm occurs, it is necessary to wait for the specification switch to be completed before troubleshooting. This can avoid the impact of changes in the dynamic operation of the equipment on the troubleshooting results. Furthermore, troubleshooting when the equipment is in a static state will not interfere with the specification switch process, thus ensuring higher safety.

[0118] Specifically, fault alarms, such as servo overload, will be triggered by flashing lights or audible sounds. Troubleshooting only requires addressing the specific faulty component; for example, adjusting only the output of the overloaded servo, without needing to adjust all servos. It should be noted that during specification switching, all bag-making equipment must be switched to the target state before subsequent operations such as production or other maintenance can be performed.

[0119] Furthermore, before obtaining the current bag type parameters of the current target product corresponding to the current bag-making cycle, the process also includes:

[0120] The bag-making equipment is powered on and started to obtain the initial bag type parameters of the initial target product corresponding to the initial cycle, and determines the initial specification parameters of the bag-making equipment corresponding to the initial target product based on the initial bag type parameters;

[0121] The initial target state of the bag-making component is determined based on the initial specification parameters, and the state adjustment component is controlled to switch the bag-making component from the initial zero position to the initial target state.

[0122] Initial bag type parameters include basic dimensional parameters such as bag width, bag thickness, and bag height. Initial specification parameters include equipment operating parameters such as face width, bottom width, and cutting length. The initial target state refers to the working state that the bag-making component needs to achieve in the initial cycle, such as the position of the width adjustment component and the rotation speed of the cutting component. The initial zero position refers to the default or initial position of the bag-making component after the equipment is powered on and started. The state adjustment component moves the bag-making component from the initial zero position to the initial target state through a drive mechanism, such as a servo motor or cylinder.

[0123] In one preferred embodiment, the servo motor calculates the initial target position based on initial specifications and uses a position sensor to provide real-time feedback on the position information of the bag-making component, thus achieving closed-loop control. Furthermore, the initial zero position can be calibrated using a mechanical limit switch or encoder to ensure that the bag-making component is in the accurate position when the equipment starts.

[0124] This process automatically acquires the parameters of the initial target product and completes the initial positioning of the bag-making component upon equipment startup, avoiding the tedious process of manual adjustment. Through the automatic control of the state adjustment component, the bag-making component can quickly and accurately switch from the initial zero position to the initial target state without relying on the operator's experience.

[0125] Furthermore, after the state adjustment component drives the bag-making component to switch from the initial zero position to the initial target state, it also includes:

[0126] Pre-run the bag-making equipment and obtain samples;

[0127] Obtain the actual bag shape parameters of the sample, compare the initial bag shape parameters with the actual bag shape parameters, and obtain the size deviation;

[0128] The size deviation control state adjustment component moves the width adjustment component from the initial target position to the adjustment position.

[0129] Specifically, the width adjustment component can move from the initial target position to the adjustment position automatically, driven by the status adjustment component, or it can be manually adjusted by an operator pressing the control button on the drive component. Furthermore, in this embodiment, after the width adjustment component moves from the initial target position to the adjustment position, no secondary adjustment is required after subsequent specification switching.

[0130] Pre-running the bag-making equipment refers to producing a small number of sample bags during a short period of operation for dimensional measurement. Actual bag parameters are obtained by measuring the samples using instruments such as a ruler to measure bag width and thickness. Dimensional deviations are calculated by comparing the actual bag parameters with the initial bag parameters, specifically representing the differences in each dimensional parameter. The calibration position is the position after fine-tuning based on the dimensional deviations from the initial target position, used to compensate for potential mechanical errors during equipment operation. In a preferred embodiment, the dimensional deviation can be automatically calculated by the control system, generating calibration commands that are sent to the status adjustment component to automatically adjust the position of the width adjustment component. It should be noted that in this embodiment, calibration is only performed after power-on or after the width adjustment component is replaced, to improve equipment efficiency while compensating for mechanical errors. This approach, by adding pre-running and calibration steps during the initial setup phase, achieves precise calibration of the bag-making component position.

[0131] Furthermore, before determining the initial target state of the bag-making components based on the initial specification parameters, the process also includes:

[0132] Determine whether the width of the initial target product exceeds the width adjustment range of the width adjustment component;

[0133] If so, replace the width adjustment component, control the state adjustment component to move the width adjustment component to the initial zero position, and control the state adjustment component to move the width adjustment component to the adjustment position according to the size deviation between the sample and the initial target product.

[0134] If not, then continue to determine whether the width of the initial target product exceeds the width adjustment range of the width adjustment component.

[0135] Specifically, the minimum width threshold of the width adjustment component refers to the range of width values ​​that the component can adjust. If the width of the initial target product exceeds this threshold range, the required width cannot be achieved by adjusting the width adjustment component, and the component must be replaced. After replacement, the width adjustment component is first moved to its initial zero position, which is the reference position of the equipment. Subsequently, a sample is obtained by pre-running the bag-making equipment, and the actual bag shape parameters of the sample are measured and compared with the initial bag shape parameters to obtain the dimensional deviation. Based on this deviation, the control state adjustment component moves the width adjustment component to the adjustment position to compensate for the deviation and ensure that the produced packaging bags meet the requirements. It should be noted that the operation of moving to the initial zero position is only required after the width adjustment component has been replaced or after the equipment is powered on for the first time.

[0136] In a preferred embodiment, the width adjustment component may include a front width adjustment template and a side width adjustment disc, wherein the front width adjustment template is used to adjust the front width of the packaging bag, and the side width adjustment disc and the front width adjustment template are used to comprehensively adjust the side width of the packaging bag. The front width adjustment range can be determined by the structural parameters of the front width adjustment template, such as the minimum adjustable width and the maximum adjustable width of the template. The adjustment position can be calculated based on the proportional relationship of the dimensional deviation; for example, for every 1mm increase in deviation, the adjustment position moves a certain distance accordingly.

[0137] As a preferred implementation, the judgment process can be integrated into the equipment control system for automated execution. Deviation-based calibration ensures adjustment accuracy and reduces the number of repeated trial production runs.

[0138] Furthermore, in a preferred embodiment, the handle portion of the packaging bag can be customized to produce handles of different specifications to accommodate different bag sizes. Specifically, the current bag type parameters also include handle width, handle length, and adhesive handle height; the current specification parameters also include handle end spacing and handle cord length.

[0139] Furthermore, based on the current bag type parameters, the current specification parameters of the bag-making equipment corresponding to the current target product are determined, including:

[0140] The handle end spacing is determined based on the handle width of the current target product, and the handle rope length is determined based on the handle length and adhesive height of the current target product.

[0141] Furthermore, the handle width is equal to the distance between the handle ends, and the handle rope length is determined according to the following formula:

[0142]

[0143] in, The length of the handle rope. The length of the handle. The height of the adhesive handle. This is an adjustment coefficient, ranging from 3 to 6, and is directly proportional to the handle length.

[0144] Specifically, handle width refers to the distance between the two ends of the handle, handle length refers to the length of the handle above the top of the bag, and adhesive handle height refers to the distance between the two ends of the handle and the top of the bag. By establishing the relationship between bag type parameters and equipment specification parameters, these steps enable automated adjustment of handle-related components.

[0145] Furthermore, in a preferred embodiment, the specifications of the bottom overlap of the packaging bag can be switched to produce packaging bags with different overlap specifications to adapt to different load-bearing or other requirements. Specifically, the current bag type parameters also include... Figure 5 The length h of the bottom fold of the bag body is shown; the current specification parameters also include the width w of the bottom flange of the bag body; wherein, the length h of the bottom fold of the bag body is equal to the width w of the bottom flange of the bag body. This method allows for switching the specifications of the folding mechanism, thereby producing packaging bags with different fold lengths.

[0146] It should be noted that the above implementation methods only illustrate the methods of changing the specifications of the bag body, bottom, handle, and bottom overlap of the packaging bag. In the actual bag manufacturing process, only one or two specifications may be changed, for example, only the specifications of the bag body and bottom may be changed, but the specifications of the handle and overlap may not be changed. Alternatively, all of the above may be changed simultaneously. Of course, other size parameters or bag type parameters of the packaging bag may also be changed.

[0147] Next, the bag-making method provided in this embodiment will be described in its entirety, taking the production of three different bag sizes after the bag-making equipment is powered on as an example. Specifically, the first batch of packaging bags has a height of 300mm, a width of 200mm, and a thickness of 100mm; the second batch has a height of 400mm, a width of 210mm, and a thickness of 100mm; and the third batch has a height of 400mm, a width of 300mm, and a thickness of 300mm. Furthermore, the dimensions of the bag bottom support component initially installed on the bag-making equipment are 90mm-110mm, and the dimensions of the width adjustment template are also 90mm-110mm.

[0148] First, the bag-making equipment is powered on and started. It acquires the initial bag type parameters (i.e., the bag width, thickness, and height of the first batch of packaging bags to be produced) for the initial target product corresponding to the initial cycle. Then, based on the initial bag type parameters, it determines the initial specification parameters of the bag-making equipment corresponding to the initial target product (the face width, bottom width, and cutting length to be input to the bag-making equipment are determined based on the bag width, thickness, and height).

[0149] Next, it is determined whether the width of the initial target product exceeds the width adjustment range of the width adjustment component. It is determined that the width of the first batch of packaging bags is 200mm, which does not match the size specification of the width adjustment template of 90mm-110mm. Therefore, the width adjustment component needs to be replaced, specifically the width adjustment template.

[0150] Next, replace the width adjustment template with one of size specifications of 190mm-210mm. The width of the initial target product should be within the width adjustment range of the width adjustment template. Move the width adjustment template to the zero position (the position where the first template and the second template meet) and input the initial specification parameters into the bag making equipment.

[0151] The initial target state of the bag-making component is determined based on the initial specification parameters, and the state adjustment component is controlled to switch the bag-making component from the initial zero position to the initial target state. That is, the servo motor controls the support, rotating shaft and other state adjustment components to move the width adjustment component and other moving components from the initial zero position to the initial target position, and controls the rotating cam and other rotating components to increase the speed from 0 to the initial target speed.

[0152] Next, the bag-making equipment is pre-run to obtain a sample. The bag width, bag thickness, and bag height of the sample are obtained (assuming a bag height of 300mm, a bag width of 202mm, and a bag thickness of 98mm), and compared with the initial bag shape parameters of the target product to obtain the size deviation (bag width deviation +2mm, bag thickness deviation -2mm). Then, based on the size deviation, the width adjustment component is controlled to move from the initial target position to the adjustment position (the first template and the second template are moved inward by 1mm, and the first disc and the second disc are moved inward by 1mm).

[0153] At the same time, it is determined whether the bottom width of the bag bottom support component matches the bottom width of the target product. Through size comparison, the size specification of the bag bottom support component is 90mm-110mm, which matches the bottom width of 100mm.

[0154] Next, the first batch of packaging bags is produced using the calibrated bag-making equipment. After the first batch of packaging bags is completed, the second batch is produced. After the first batch of packaging bags is completed, the equipment is paused (without powering off) and a specification switching operation is performed.

[0155] Obtain the current bag type parameters for the current target product corresponding to the current bag-making cycle, and determine the current specification parameters of the bag-making equipment corresponding to the current target product based on the current bag type parameters. That is, obtain the bag height, bag width, and bag thickness of the second batch of packaging bags, and determine the bottom width, top width, and cutting length based on the bag height, bag width, and bag thickness.

[0156] Next, it is determined whether the width adjustment range of the width adjustment template matches the width of the target product. Since the width adjustment template was changed when the first batch of packaging bags was produced, the size of the width adjustment template is now 190mm-210mm, which matches the width of the second batch of packaging bags. Therefore, there is no need to change the width adjustment template or adjust it.

[0157] At the same time, determine whether the bottom width exceeds the matching range of the bottom width of the bag bottom support component. If the bottom width of 100mm is consistent with the size specification of the bag bottom support component of 90mm-110mm, no replacement is required.

[0158] Then, the width, bottom width, and cutting length are input into the bag-making equipment via the human-machine interface screen.

[0159] The control device of the bag-making equipment can determine the current target state of the bag-making components based on the current specifications and parameters. This means determining the position or rotational speed of each component and controlling the state adjustment component to directly switch the bag-making components from the current working state (i.e., the state after producing the first batch of packaging bags) to the current target state. For example, the width adjustment template moves from (100,0,0) to (105,0,0). After the state switch is completed, the production of the second batch of packaging bags begins.

[0160] After the second batch of packaging bags is produced, the production of the third batch of packaging bags will begin. After the second batch of packaging bags is produced, the equipment will be paused (without powering off) and a specification switching operation will be performed.

[0161] First, obtain the height, width, and thickness of the third batch of packaging bags, and determine the bottom width, front width, and cutting length based on the bag height, width, and thickness.

[0162] Next, it was determined whether the width adjustment range of the width adjustment template matched the width of the target product. The width adjustment template's dimensions were 190mm-210mm, which did not match the 300mm width of the third batch of packaging bags, requiring the template to be replaced. Simultaneously, it was determined whether the bottom width exceeded the adaptability range of the bag bottom support component. The bottom width of 300mm did not match the 90mm-110mm dimensions of the bag bottom support component, requiring the component to be replaced.

[0163] After the replacement is completed, the width adjustment template needs to be returned to the zero position. The width, bottom width, and cutting length are then input into the bag making equipment through the human-machine interface screen on the bag making equipment. The pre-production process is then repeated, and the width adjustment component is fine-tuned based on the size deviation between the sample obtained from the pre-production and the target.

[0164] After fine-tuning, the third batch of packaging bags will be put into formal production. The equipment will be powered down after production is completed.
