Description

Technical Field

[0001] This invention relates to the field of integrated sewing and automatic shuttle changing technology, and more particularly to a method and system integrating sewing and automatic shuttle changing. Background Technology

[0002] Existing automatic shuttle changing technology employs a split control design, consisting of a sewing machine control system, a shuttle changing control system, and a shuttle changing device. In practice, these three systems require collaboration among technical personnel to achieve automatic shuttle changing. Significant differences exist in the control system architecture and motion signal transmission / reception methods between different technology companies, leading to significant development difficulties, long development cycles, and high communication costs when collaborating. Furthermore, there is the issue of shuttle changing data synchronization. Since the independent sewing machine control system and the shuttle changing control system essentially lack data communication capabilities, in actual operation, shuttle changing data may not be updated in a timely manner, or deviations may occur, leading to potential problems during automatic shuttle changing. Summary of the Invention

[0003] To address the technical barriers between sewing and automatic shuttle changing, the present invention aims to provide a method that integrates sewing and automatic shuttle changing.

[0004] The above-mentioned objective of this invention is achieved through the following technical solution:

[0005] A method integrating sewing and automatic shuttle changing includes the following steps:

[0006] Before starting sewing work, determine whether to trigger the automatic shuttle change process based on the working parameters;

[0007] Remove the used bobbin from the sewing machine's rotary hook and place it in the empty bobbin position on the bobbin tray;

[0008] Take a new bobbin from the spare bobbin tray, place the new bobbin into the rotary hook of the sewing machine, and begin the sewing process.

[0009] By adopting the above technical solution, the integrated control of sewing and automatic shuttle changing can be realized, solving the problems of signal delay, signal loss and signal error between sewing action and automatic shuttle changing action, and solving the communication and technical obstacles between the two. The operation is more stable and reliable, and has extremely high application value.

[0010] In a preferred embodiment, the present invention can be further configured as follows:

[0011] Set working parameters, including the maximum sewing thread length of the bobbin or the maximum number of sewing times of the bobbin;

[0012] Based on the aforementioned working parameters, determine whether the remaining sewing bobbin thread meets the required needle and thread length for sewing;

[0013] If the determination is yes, then the automatic shuttle change process will not be triggered;

[0014] If the result is negative, the automatic shuttle switching process is triggered.

[0015] By adopting the above scheme and setting working parameters, the automatic shuttle changing process can be adaptively performed according to the working parameters, improving the flexibility and adaptability of the automatic shuttle changing process. The working parameters can be set to the maximum sewing thread length of the bobbin or the maximum number of sewing times of the bobbin, which can be set according to actual needs, making it quite flexible. Based on the working parameters, it can be determined whether the remaining sewing bobbin thread meets the required needle and thread length for sewing, and can quickly determine whether an automatic shuttle changing process is needed, thus improving the efficiency of automatic shuttle changing.

[0016] In a preferred embodiment, the present invention can be further configured as follows:

[0017] Before triggering the automatic shuttle change process, determine whether the sewing machine is in a stopped state;

[0018] If the sewing machine is determined to be stopped, the automatic shuttle change process is initiated.

[0019] If the sewing machine is determined to be in operation, the process of waiting for the sewing machine to stop will begin.

[0020] By adopting the above technical solution, it is first determined whether the sewing machine is working, so as to avoid the conflict between the sewing process and the automatic shuttle changing process.

[0021] In a preferred embodiment, the present invention can be further configured as follows:

[0022] After removing the used bobbin from the sewing machine's rotary hook, determine whether the bobbin disc is in the empty bobbin position.

[0023] If the bobbin disc is in an empty bobbin position, then the used bobbin is placed in the empty bobbin position of the bobbin disc.

[0024] If the position of the bobbin disc is not an empty bobbin position, then rotate to the next position of the bobbin disc and make the judgment again until the position of the bobbin disc is determined to be an empty bobbin position, and place the used bobbin into the empty bobbin position of the bobbin disc.

[0025] By adopting the above technical solutions, the efficiency of automatic shuttle changing can be improved.

[0026] In a preferred embodiment, the present invention can be further configured as follows:

[0027] Based on the photoelectric sensor, a photoelectric sensing IO signal is emitted to the position of the spindle disk, and the photoelectric sensing IO signal is sensed and received back.

[0028] If the returned photoelectric sensor IO signal is low, then the position of the bobbin disc is determined to be an empty bobbin position.

[0029] If the returned photoelectric sensor IO signal is high, then it is determined that the position of the bobbin is not an empty bobbin position.

[0030] By adopting the above technical solution, the position of the bobbin disk is determined by a photoelectric sensor to determine whether it is an empty bobbin position. The determination accuracy is higher and the response speed is faster, which can effectively improve the efficiency of the automatic shuttle changing process.

[0031] In a preferred embodiment, the present invention can be further configured as follows:

[0032] If it is determined that none of the positions on the bobbin disc are empty bobbin positions, the automatic shuttle changing process is paused and an error is reported.

[0033] By adopting the above technical solutions, the efficiency of the automatic shuttle changing process can be effectively improved and errors can be avoided; error display can provide prompts to operators.

[0034] In a preferred embodiment, the present invention can be further configured as follows:

[0035] Determine if a new bobbin is available at the position of the spare bobbin disc;

[0036] If a new bobbin is available at the location of the spare bobbin disc, the new bobbin is removed and placed into the rotary hook of the bobbin disc.

[0037] If no new bobbin is found at the position of the spare bobbin disc, the process moves to the next position of the spare bobbin disc and checks again until a new bobbin is found at the position of the spare bobbin disc. The new bobbin is then removed and placed into the shuttle of the bobbin disc.

[0038] By adopting the above technical solutions, the efficiency of automatic shuttle changing can be effectively improved.

[0039] In a preferred embodiment, the present invention can be further configured as follows:

[0040] Based on the photoelectric sensor, a photoelectric sensing IO signal is transmitted to the position of the spare shuttle core disk, and the photoelectric sensing IO signal is sensed and received back;

[0041] If the returned photoelectric sensor IO signal is high, it is determined that there is a new bobbin in the spare bobbin tray, and the new bobbin is taken out from the corresponding position and placed into the rotary hook of the sewing machine.

[0042] If the returned photoelectric sensor IO signal is low, it is determined that there is no new bobbin in the spare bobbin disk.

[0043] By adopting the above technical solution, the presence of a new shuttle core in the internal shuttle core disk can be determined by photoelectric sensors, resulting in higher accuracy and faster response speed, which can effectively improve the efficiency of the automatic shuttle changing process.

[0044] In a preferred embodiment, the present invention can be further configured as follows:

[0045] If it is determined that there is no new bobbin in any position of the spare bobbin disc, the automatic bobbin changing process is paused and an error is reported.

[0046] By adopting the above technical solutions, the efficiency of the automatic shuttle changing process can be effectively improved and errors can be avoided; error display can provide prompts to operators.

[0047] In a preferred embodiment, the present invention can be further configured as follows:

[0048] After placing the new bobbin into the rotary hook of the sewing machine, determine whether the new bobbin is placed correctly;

[0049] If it is determined that the new bobbin is correctly placed, the automatic shuttle changing process will proceed normally.

[0050] If it is determined that the new bobbin is not placed correctly, the automatic shuttle changing process is paused and an error is reported.

[0051] By adopting the above technical solutions, the efficiency of automatic shuttle changing can be improved.

[0052] In a preferred embodiment, the present invention can be further configured as follows:

[0053] Based on the photoelectric sensor, the photoelectric sensor transmits photoelectric sensing IO signals to the new shuttle core and senses and receives the returned photoelectric sensing IO signals.

[0054] If the returned photoelectric sensor IO signal is high, then it is determined that the new shuttle core is correctly placed;

[0055] If the returned photoelectric sensor IO signal is low, it is determined that the new bobbin is not placed correctly.

[0056] By adopting the above technical solution, the photoelectric sensor determines whether the new shuttle core is correctly placed, resulting in higher accuracy and faster response, which can effectively improve the efficiency of the automatic shuttle changing process.

[0057] In a preferred embodiment, the present invention can be further configured as follows:

[0058] When the new bobbin is correctly placed, the sewing process is determined based on the working parameters to see if it is complete.

[0059] If it is determined that the sewing process is not completed, then the sewing process continues;

[0060] If it is determined that the sewing process has been completed, a notification will be issued indicating that the sewing process has been completed.

[0061] By adopting the above technical solutions, the efficiency of automatic shuttle changing can be effectively improved.

[0062] The second objective of this invention is to provide an integrated sewing and automatic shuttle changing system.

[0063] The above-mentioned objective 2 of the present invention is achieved through the following technical solution:

[0064] The judgment module is used to determine whether to trigger the automatic shuttle change process based on the working parameters.

[0065] The operation module is used to remove used bobbins from the sewing machine's rotary hook and place them in the empty bobbin position on the bobbin tray, and to remove new bobbins from the spare bobbin tray and place them into the sewing machine's rotary hook.

[0066] The third objective of this invention is to provide a computer-readable storage medium capable of storing corresponding programs.

[0067] The above-mentioned objective three of this invention is achieved through the following technical solution:

[0068] A computer-readable storage medium storing a computer program that can be loaded by a processor and executed any of the above-described sewing and automatic shuttle changing methods.

[0069] In summary, the present invention has at least one of the following beneficial technical effects:

[0070] 1. The integrated control of sewing and automatic shuttle changing solves the problems of signal delay, signal loss and signal error between sewing and automatic shuttle changing actions, and also solves the communication and technical barriers between the two, making the operation more stable and reliable, and has extremely high application value.

[0071] 2. After the automatic shuttle change is completed, the sewing work will start automatically without manual intervention.

[0072] 3. By setting working parameters to control the automatic shuttle changing process, the flexibility and adaptability of automatic shuttle changing are improved, thus increasing the efficiency of automatic shuttle changing.

[0073] 4. The photoelectric sensor is used to determine whether the bobbin tray is empty, whether there is a new bobbin in the spare bobbin tray, and whether the new bobbin is placed correctly. The judgment is more accurate and the response speed is faster, which can effectively improve the efficiency of the automatic shuttle changing process.

[0074] 5. A one-click pause or termination of the automatic shuttle switching process can be added, making operation simpler.

[0075] 6. It can be expanded to include other auxiliary action processes to improve the efficiency of automatic shuttle changing.

[0076] 7. If problems occur during later operation and maintenance, it is possible to quickly determine whether the problem lies in the sewing system or the automatic shuttle changing system, which facilitates repair. Attached Figure Description

[0088] Explanation of the attached diagram labels: 1. Judgment module; 2. Operation module. Detailed Implementation

[0089] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 The present invention will be described in further detail below.

[0090] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0091] This invention provides a method and system for integrating sewing and automatic shuttle changing, comprising: determining whether to trigger the automatic shuttle changing process based on working parameters before starting sewing work; removing the used shuttle from the rotary hook of the sewing machine and placing it in the empty shuttle position of the shuttle disc; taking a new shuttle from the spare shuttle disc, placing the new shuttle in the rotary hook of the sewing machine, and entering the sewing workflow.

[0092] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0093] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0094] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0095] This invention provides a method for integrating sewing and automatic shuttle changing, the main process of which is described below.

[0096] like Figure 1 As shown, an embodiment of the present invention provides a method for integrating sewing and automatic shuttle changing, comprising the following steps:

[0097] Reference Figure 1 Step S100: Before starting the sewing work, determine whether to trigger the automatic shuttle change process based on the working parameters;

[0098] Specifically, such as Figure 2As shown, step S100 specifically includes step S110, setting working parameters;

[0099] Specifically, working parameters for automatic shuttle changing are set, and the triggering conditions for the automatic shuttle changing process are set through the working parameters. The working parameters include the maximum sewing length of the bobbin or the maximum number of sewing times of the bobbin.

[0100] S120. Based on the working parameters, determine whether the remaining sewing thread bobbin meets the required needle and thread length for sewing;

[0101] S130, Automatic shuttle change process is not triggered;

[0102] S140, trigger the automatic shuttle change process.

[0103] Specifically, in step S120, based on the maximum sewing thread length or maximum sewing count of the bobbin in the working parameters, it is determined whether the remaining bobbin thread allowance in the currently used bobbin meets the needle thread length required for this sewing. If it is determined that the remaining bobbin thread meets the needle thread length required for sewing, then proceed to step S130, without triggering the automatic bobbin change process, and start the sewing work at the same time, and save the needle thread length of this sewing to the working parameter "used bobbin thread length"; if it is determined that the remaining bobbin thread does not meet the needle thread length required for sewing, then proceed to step S140, pause the sewing work, and trigger the automatic bobbin change process.

[0104] More, such as Figure 3 As shown, the step of determining whether to trigger the automatic shuttle change process based on working parameters also includes:

[0105] Step S141: Before triggering the automatic shuttle change process, determine whether the sewing machine is in a stopped state;

[0106] Step S142: Start the automatic shuttle changing process;

[0107] Step S143: Enter the waiting process for the sewing machine to stop.

[0108] Specifically, before triggering the automatic shuttle change process, step S141 is entered to determine whether the sewing machine is in a stopped state. If the sewing machine is determined to be in a stopped state, step S142 is entered to start the automatic shuttle change process; if the sewing machine is determined to be in a working state, step S143 is entered to enter the waiting process for the sewing machine to stop. The automatic shuttle change process is then started after the sewing machine enters a stopped state.

[0109] Reference Figure 1 Step S200: Remove the used bobbin from the rotary hook of the sewing machine and place it in the empty bobbin position on the bobbin disc.

[0110] Specifically, such as Figure 4As shown, step S200 specifically includes step S210: after removing the used bobbin from the rotary hook of the sewing machine, determine whether the position of the bobbin disc is the empty bobbin position.

[0111] Step S220: Place the used bobbin into the empty bobbin position on the bobbin disc;

[0112] Step S230: Rotate to the next position of the bobbin disc.

[0113] Specifically, in step S200, after the used bobbin is removed from the sewing machine's rotary hook, it needs to be placed into the empty bobbin position on the bobbin tray. At this time, it is necessary to determine whether the corresponding position on the bobbin tray is an empty bobbin position, that is, whether there is an empty bobbin in that position. If it is determined that the position on the bobbin tray is an empty bobbin position, then proceed to step S220 and place the used bobbin into the empty bobbin position; if it is determined that there are other empty bobsbins in the position on the bobbin tray, that is, it is not an empty bobbin position, then proceed to step S230 and do not place the used bobbin into that position.

[0114] Furthermore, when it is determined that the position of the bobbin disc is not an empty bobbin position, proceed to step S230, rotate the bobbin disc to the next position by the motor, and repeat step S210 to determine whether the position is an empty bobbin position again, until the nearest empty bobbin position of the bobbin disc is found, and the used bobbin is placed in the empty bobbin position of the bobbin disc.

[0115] In one optional implementation of this embodiment, the position of the bobbin disk is determined based on a photoelectric sensor to determine whether it is an empty bobbin position.

[0116] Specifically, such as Figure 5 As shown, the step of determining whether the position of the bobbin disk is an empty bobbin position based on the photoelectric sensor includes step S211: transmitting a photoelectric sensing IO signal to the position of the bobbin disk based on the photoelectric sensor, and sensing and receiving the returned photoelectric sensing IO signal.

[0117] S212. Determine that the position of the bobbin disc is an empty bobbin position;

[0118] S213. Determine that the position of the bobbin disc is not an empty bobbin position.

[0119] Specifically, in step S211, a photoelectric sensing IO signal is emitted to the position of the bobbin based on the photoelectric sensor, and the returned photoelectric sensing IO signal is sensed and received. If the returned photoelectric sensing IO signal is low, then proceed to step S212 to determine that the position of the bobbin is an empty bobbin position; if the returned photoelectric sensing IO signal is high, then proceed to step S213 to determine that the position of the bobbin is not an empty bobbin position.

[0120] It should be noted that when it is determined that all positions on the bobbin disc are not empty bobbin positions, the automatic shuttle changing process is paused and an error is reported.

[0121] Specifically, the maximum number of bobbins a bobbin can hold is limited. This maximum number of bobbins can be set by the working parameters. If the bobbin has rotated one full circle and still has not found an empty bobbin, an error message will be displayed: "Bobbin is full, please replace bobbin". After the bobbin is replaced, the process will proceed to step S210 again.

[0122] Reference Figure 1 Step S300: Take out a new bobbin from the spare bobbin tray, place the new bobbin into the rotary hook of the sewing machine, and start the sewing process.

[0123] Specifically, such as Figure 6 As shown, step S300 specifically includes step S310: determining whether a new bobbin exists at the position of the spare bobbin disc;

[0124] Step S320: Take out the new bobbin and place it into the rotary hook of the bobbin disc;

[0125] Step S330: Rotate to the next position of the spare bobbin disc.

[0126] Specifically, during the bobbin replacement process, step S310 is required to determine whether a new bobbin exists at the corresponding position of the spare bobbin disc. If a new bobbin exists at the corresponding position of the spare bobbin disc, step S320 is required to remove the new bobbin and place it into the shuttle of the bobbin disc. If a new bobbin does not exist at the corresponding position of the spare bobbin disc, step S330 is required to search for a new bobbin.

[0127] Furthermore, when it is determined that there is no new bobbin at the corresponding position of the spare bobbin disc, the process proceeds to step S330, where the spare bobbin disc is rotated to the next position by a motor, and step S310 is repeated to determine whether there is a new bobbin at that position again, until a new bobbin is found. The new bobbin is then removed and placed into the shuttle of the bobbin disc.

[0128] In one optional implementation of this embodiment, the location of the spare bobbin disk is determined based on a photoelectric sensor to determine whether a new bobbin exists.

[0129] Specifically, such as Figure 7 As shown, determining whether a new bobbin exists at the position of the spare bobbin disc based on a photoelectric sensor includes step S311: transmitting a photoelectric sensing IO signal to the position of the spare bobbin disc based on the photoelectric sensor, and sensing and receiving the returned photoelectric sensing IO signal.

[0130] S312. Determine that there is a new bobbin in the spare bobbin tray, take out the new bobbin from the corresponding position, and place the new bobbin into the rotary hook of the sewing machine;

[0131] S313. Determine that there is no new bobbin in the spare bobbin disc.

[0132] Specifically, in step S311, a photoelectric sensor transmits a photoelectric sensing IO signal to the position of the spare bobbin tray based on the photoelectric sensor, and senses and receives the returned photoelectric sensing IO signal. If the returned photoelectric sensing IO signal is high, then proceed to step S312, determine that there is a new bobbin in the spare bobbin tray, take out the new bobbin from the corresponding position, and place the new bobbin into the rotary hook of the sewing machine; if the returned photoelectric sensing IO signal is low, then proceed to step S313, determine that there is no new bobbin in the spare bobbin tray, and then search for the next new bobbin.

[0133] It should be noted that when it is determined that there is no new bobbin in any position of the spare bobbin disc, the automatic bobbin changing process is paused and an error is reported.

[0134] Specifically, the maximum number of bobbins a bobbin can hold is limited. This maximum number of bobbins can be set by the working parameters. If a new bobbin is not found after the spare bobbin rotates once, an error message will be displayed: "The spare bobbin has run out of bobbins. Please replace it with a new spare bobbin!" After the spare bobbin is replaced, the process will proceed to step S310 again.

[0135] In one optional implementation of this embodiment, such as Figure 8 As shown, step S300 specifically includes step S331, after placing the new bobbin into the rotary hook of the sewing machine, determining whether the new bobbin is placed correctly;

[0136] Step S332: Perform the automatic shuttle changing process normally;

[0137] Step S333: Pause the automatic shuttle change process and report an error.

[0138] Specifically, in step S331, after placing the new bobbin into the rotary hook of the sewing machine, it is necessary to determine whether the new bobbin is placed correctly. Only when the new bobbin is placed correctly can the subsequent automatic shuttle change process proceed. If it is determined that the new bobbin is placed correctly, then proceed to step S332 and the automatic shuttle change process proceeds normally; if it is determined that the new bobbin is not placed correctly, then proceed to step S333, pause the automatic shuttle change process, and report an error.

[0139] In one optional implementation of this embodiment, the new bobbin is placed correctly based on a photoelectric sensor.

[0140] Specifically, such as Figure 9As shown, the step of determining whether the new bobbin is correctly placed based on the photoelectric sensor's back photoelectric sensor IO signal includes step S3311: transmitting a photoelectric sensor IO signal to the new bobbin based on the photoelectric sensor, and sensing and receiving the back photoelectric sensor IO signal.

[0141] S3312. Determine that the new bobbin is correctly placed;

[0142] S3313. It is determined that the new bobbin is not placed correctly.

[0143] Specifically, in step S3311, a photoelectric sensing IO signal is emitted to the new bobbin based on the photoelectric sensor, and the returned photoelectric sensing IO signal is sensed and received; if the returned photoelectric sensing IO signal is high level, then proceed to step S3312 to determine that the new bobbin is correctly placed; if the returned photoelectric sensing IO signal is low level, then proceed to step S3313 to determine that the new bobbin is not correctly placed.

[0144] It should be noted that when it is determined that the new bobbin is not placed correctly, an error message "New bobbin error, please check the equipment!" will be displayed. After the new bobbin is replaced, the process will proceed to step S320 again until the new bobbin is placed correctly.

[0145] Furthermore, when the new bobbin is correctly placed, the sewing process is determined based on the working parameters to determine whether it is complete.

[0146] Specifically, such as Figure 10 As shown, when the new bobbin is correctly placed, determining whether the sewing process is completed based on the working parameters includes step S341: when the new bobbin is correctly placed, determining whether the sewing process is completed based on the working parameters;

[0147] Step S342: Continue the sewing process;

[0148] Step S343: Issue a notification that the sewing process is complete.

[0149] Specifically, after the shuttle change is completed, step S341 is entered, and the sewing process is judged based on the working parameters. If the sewing process is not judged to be completed, step S342 is entered to continue the sewing process; if the sewing process is judged to be completed, step S343 is entered, and a prompt "Automatic shuttle change process has been completed!" is issued.

[0150] In an optional implementation of this embodiment, the method further includes a function to pause or terminate the automatic shuttle process with one click.

[0151] In summary, by adopting the above technical solutions, the integrated control of sewing and automatic shuttle changing solves the problems of signal delay, signal loss, and signal errors between sewing and automatic shuttle changing actions, and resolves communication and technical barriers between the two. This results in more stable and reliable operation with high application value. After automatic shuttle changing, sewing work resumes automatically without manual intervention. By setting operating parameters to control the automatic shuttle changing process, the flexibility and adaptability of automatic shuttle changing are improved, thus increasing its efficiency. Photoelectric sensors are used to determine whether the bobbin disc is empty, whether a new bobbin is present in the spare bobbin disc, and whether the new bobbin is correctly placed, resulting in higher accuracy and faster response, effectively improving the efficiency of the automatic shuttle changing process. A one-click pause or termination of the automatic shuttle changing process can be added, simplifying operation. Other auxiliary action processes can be expanded to improve the efficiency of automatic shuttle changing. In later operation and maintenance, if problems occur, it is possible to quickly determine whether the problem originates in the sewing system or the automatic shuttle changing system, facilitating repair.

[0152] Reference Figure 11 This invention provides an integrated sewing and automatic shuttle changing system, corresponding one-to-one with the integrated sewing and automatic shuttle changing method described in the above embodiments. The system includes a judgment module 1 and an operation module 2. Detailed descriptions of each functional module are as follows:

[0153] Module 1 is used to determine whether to trigger the automatic shuttle change process based on the working parameters;

[0154] Operation module 2 is used to remove used bobbins from the rotary hook of the sewing machine and place them in the empty bobbin position of the bobbin tray, and to remove new bobbins from the spare bobbin tray and place them in the rotary hook of the sewing machine.

[0155] This invention also provides a computer-readable medium storing a computer program that can be loaded by a processor and executed by any of the above-described sewing and automatic shuttle changing methods. When executed by the processor, the computer program performs the following steps:

[0156] Step S100: Before starting the sewing work, determine whether to trigger the automatic shuttle change process based on the working parameters;

Claims

1. A method integrating sewing and automatic shuttle changing, characterized in that, Includes the following steps: Before starting sewing, the system determines whether to trigger the automatic shuttle change process based on working parameters. Specific steps include: setting working parameters, which include the maximum thread length that the bobbin can sew or the maximum number of times the bobbin can sew; determining whether the remaining bobbin thread meets the required needle and thread length based on the working parameters; if yes, the automatic shuttle change process is not triggered; if no, the automatic shuttle change process is triggered. The system also includes: before triggering the automatic shuttle change process, determining whether the sewing machine is in a stopped state; if the sewing machine is stopped, the automatic shuttle change process is initiated; if the sewing machine is in a working state, a waiting process for the sewing machine to stop is initiated. The process of removing a used bobbin from the sewing machine's rotary hook and placing it in the empty bobbin position on the bobbin tray involves the following steps: After removing the used bobbin from the sewing machine's rotary hook, determine if the bobbin tray is in an empty bobbin position; if the bobbin tray is in an empty bobbin position, place the used bobbin in that position; if the bobbin tray is not in an empty bobbin position, rotate to the next position on the bobbin tray and repeat the determination until the bobbin tray is determined to be in an empty bobbin position, and then place the used bobbin in that position; the process also includes: if all positions on the bobbin tray are determined to be non-empty bobbin positions, pause the automatic bobbin changing process and report an error. The process involves taking a new bobbin from the spare bobbin tray, placing it into the rotary hook of the sewing machine, and initiating the sewing workflow. Specific steps include: determining if a new bobbin exists at a given position on the spare bobbin tray; if a new bobbin exists at that position, removing it and placing it into the rotary hook; if no new bobbin exists at that position, moving to the next position on the spare bobbin tray and repeating the determination until a new bobbin is found at that position, removing it and placing it into the rotary hook. Further steps include: if no new bobbin exists at any position on the spare bobbin tray, pausing the automatic bobbin change process and issuing an error message. The method further includes: after placing the new bobbin into the rotary hook of the sewing machine, determining whether the new bobbin is correctly placed; if the new bobbin is correctly placed, proceeding with the automatic shuttle change process normally; if the new bobbin is not correctly placed, pausing the automatic shuttle change process and reporting an error.

2. A sewing and automatic shuttle changing integrated system, characterized in that, include: The judgment module determines whether to trigger the automatic shuttle change process based on working parameters before starting sewing. Specific steps include: setting working parameters, including the maximum sewing thread length or the maximum number of sewing passes the bobbin can perform; determining whether the remaining bobbin thread length meets the required sewing thread length based on the working parameters; if yes, the automatic shuttle change process is not triggered; if no, the automatic shuttle change process is triggered. Specific steps also include: determining whether the sewing machine is in a stopped state before triggering the automatic shuttle change process; if the sewing machine is in a stopped state, the automatic shuttle change process is initiated; if the sewing machine is in a working state, a waiting process for the sewing machine to stop is entered. The operation module is used to remove used bobbins from the rotary hook of the sewing machine and place them in the empty bobbin position of the bobbin tray. Specific steps include: after removing the used bobbin from the rotary hook, determining if the bobbin tray is in an empty bobbin position; if the bobbin tray is in an empty bobbin position, placing the used bobbin in that position; if the bobbin tray is not in an empty bobbin position, rotating to the next position of the bobbin tray and re-determining, until the bobbin tray is determined to be in an empty bobbin position, and then placing the used bobbin in that position. Specific steps also include: when all positions on the bobbin tray are determined to be non-empty bobbin positions, pausing the automatic bobbin changing process and reporting an error; taking a new bobbin from the spare bobbin tray, placing the new bobbin in the rotary hook of the sewing machine, and resuming the sewing workflow. The steps include: determining whether a new bobbin exists at the position of the spare bobbin tray; if a new bobbin exists at the position of the spare bobbin tray, removing the new bobbin and placing it into the rotary hook of the sewing machine; if a new bobbin does not exist at the position of the spare bobbin tray, moving to the next position of the spare bobbin tray and determining again, until a new bobbin exists at the position of the spare bobbin tray, removing the new bobbin and placing it into the rotary hook of the sewing machine; the specific steps also include: when it is determined that no new bobbin exists at any position of the spare bobbin tray, pausing the automatic bobbin changing process and reporting an error; the integrated sewing and automatic bobbin changing method also includes: after placing the new bobbin into the rotary hook of the sewing machine, determining whether the new bobbin is correctly placed; if it is determined that the new bobbin is correctly placed, proceeding with the automatic bobbin changing process normally; if it is determined that the new bobbin is not correctly placed, pausing the automatic bobbin changing process and reporting an error.
