Technical Field

[0001] The present application relates to sewing machine technology, and more particularly to a sewing machine pedal acceleration method, system and medium for automatically adapting a sewing machine pedal acceleration method. Background Art

[0002] In traditional sewing industries, such as clothing, luggage, and automotive interiors, sewing equipment is required in mass production. However, due to the different operating habits and skill levels of each operator, the configuration parameters uniformly distributed for sewing equipment may not fully conform to the operating habits of the operators.

[0003] At present, the acceleration curve of the sewing machine pedal to control the speed is fixed, and the fixed opening matches the corresponding speed. For unskilled workers, the most basic problem of the universal acceleration curve is the control of the accelerator pedal. If you are not proficient in operating the accelerator pedal, you will be sensitive to the acceleration when operating the pedal at the beginning, which will cause problems such as uneven stitches, skewness, and fabric stacking, which will eventually lead to defects in the processed clothing.

[0004] Therefore, in order to ensure the stability of production quality, it is necessary to adaptively adjust the acceleration of the sewing machine pedal according to the operator's proficiency in processing products and sewing machines, so as to help unskilled workers operate sewing machines and reduce the skill requirements of unskilled workers in garment production.

[0033] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0035] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0036] It should be noted that the most basic problem for unskilled workers to operate sewing machines is the control of the accelerator pedal. If the accelerator pedal is not operated skillfully, problems such as uneven stitches, skewness, and fabric stacking will occur, which will lead to reduced clothing quality and unguaranteed production efficiency.

[0037] The following embodiments of the present application provide an automatically adaptive sewing machine pedal acceleration method, system and medium, which can adaptively adjust the sewing machine pedal acceleration according to the operator's proficiency in processing products and sewing machines, so as to help unskilled workers operate sewing machines and reduce the skill requirements of unskilled workers in clothing production. Below, the technical solutions in the embodiments of the present application will be described in detail in conjunction with the drawings in the embodiments of the present application.

[0038] At present, the speed regulator of sewing machines changes the relative position of the magnetic block inside the speed regulator and the electronic components on the circuit board by pulling the lever. The speed regulator lever changes with the pedal opening. The more the pedal is stepped forward, the greater the lever angle offset, and the greater the relative position of the magnetic block and the electronic components. The change in relative position changes the magnetic field strength, and the Hall signal received by the electronic components changes linearly, changing the voltage value output by the speed regulator.

[0039] like Figure 1 As shown, this embodiment provides an automatically adaptive sewing machine pedal acceleration method, including steps S1 to S3.

[0040] Take, for example, obtaining the processing data of a sewing machine pedal for the first three products processed by an operator.

[0041] Step S1, obtaining processing data of the sewing machine pedal corresponding to the first several products processed by the operator.

[0042] Specifically, the processing data is the relative position change value between the magnetic block inside the pedal and the electronic components on the circuit board when the opening degree of the sewing machine pedal changes to the maximum.

[0043] Specifically, the processing data of the first three products are recorded as: L 变1 , L 变2 , L 变3 That is, when the opening of the sewing machine pedal changes the most during the processing of the first product, the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board is L 变1 When processing the second product, the relative position change value of the magnetic block inside the pedal and the electronic components on the circuit board when the opening of the sewing machine pedal changes the most is L 变2 When processing the first product, the relative position change value of the magnetic block inside the pedal and the electronic components on the circuit board when the opening of the sewing machine pedal changes the most is L 变3 .

[0044] Step S2: determining whether the operator is an unskilled worker based on the processing data.

[0045] like Figure 2 As shown, in one embodiment, determining whether the operator is a skilled worker includes steps S21 to S23.

[0046] Step S21, according to the relative position change value, obtaining a fluctuation value of a maximum value-a minimum value of a plurality of relative position change values ​​between the magnetic block and the electronic component, and an average value of a plurality of the relative position change values.

[0047] Specifically, the fluctuation value of the maximum value - minimum value of the relative position change value of the magnetic block and the electronic component of the first three products is recorded as L 波 , for example L 变1 <L 变2 <L 变3 , then L 波 =L 变3 -L 变1 The average value of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board of the first three products is recorded as L 平 ;but

[0048]

[0049] Step S22: Obtain the fluctuation amplitude of the relative position change according to the fluctuation value and the average value.

[0050] The fluctuation range L of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board of the first three products 幅 It is expressed as:

[0051]

[0052] Among them, L 波 is the fluctuation value of the maximum value - minimum value of the relative position change between the magnetic block and the electronic components of the first three products, L 变1 It is the relative position change value of the magnetic block inside the pedal and the electronic components on the circuit board when the opening degree of the sewing machine pedal changes the most when processing the first product.

[0053] Step S23: Compare the fluctuation amplitude with a first preset condition to determine whether the operator is a skilled worker or an unskilled worker.

[0054] The unskilled workers include: first-level unskilled workers and second-level unskilled workers.

[0055] Specifically, when the fluctuation amplitude is greater than a first preset threshold, the operator is a first-level unskilled worker; when the fluctuation amplitude is greater than a second threshold and not greater than the first preset threshold, the operator is a second-level unskilled worker; when the fluctuation amplitude is not greater than the second preset threshold, the operator is a skilled worker.

[0056] In this embodiment, the first preset threshold is set to 30% and the second preset threshold is set to 10%. Then,

[0057] When L 幅 >30%, the operator is a first-level unskilled worker;

[0058] When 10% <L 幅 When the rate is ≤30%, the operator is a Level 2 unskilled worker;

[0059] When L 幅 When ≤10%, the operator is a skilled worker.

[0060] It should be noted that the first preset threshold value and the second preset threshold value are not just 30% and 10%, respectively, and can be modified according to actual processing and production requirements.

[0061] Step S3: If yes, the maximum acceleration of the sewing machine pedal is automatically adjusted according to the processing data to adapt to the operation of the operator.

[0062] Specifically, when the operator is an unskilled worker, according to the processing data of the first three products obtained: L 变1 , L 变2 , L 变3 , obtain the sensitive acceleration of the operator, and use the sensitive acceleration as the maximum acceleration of the sewing machine pedal.

[0063] like Figure 3 As shown, in one embodiment, adjusting the maximum acceleration of the sewing machine pedal includes steps S31 to S32.

[0064] Step S31, obtaining the sensitive acceleration value of the sewing machine operated by the unskilled worker according to the processing data.

[0065] Specifically, the sensitive acceleration value is expressed by the formula:

[0066]

[0067] Among them, a 敏n Expressed as sensitive acceleration value, L 变n is the minimum or middle value of the processing data of the first several processed products, L max It indicates the maximum value of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board when the opening of the sewing machine pedal changes the most within the voltage change range, t n It is represented by the time point corresponding to the minimum value or the middle value in the processing data of the first several processed products. maxIt indicates the maximum voltage value of the pedal when the sewing machine is running, V0 indicates the highest voltage value at which the speed of the motor inside the pedal is stable when the sewing machine is running, and N indicates the corresponding change relationship between the speed of the motor inside the pedal and the voltage value after the voltage value exceeds V0.

[0068] Specifically, when the unskilled worker is a first-level unskilled worker, L 变n is the minimum value of the processing data of the first several processed products, t n It is represented by the time point corresponding to the minimum value of the processing data of the first several processed products obtained; when the unskilled worker is a second-level unskilled worker, L 变n is the median value of the processing data of the first several processed products, t n It is represented by the time point corresponding to the middle value of the processing data of the first several processed products obtained.

[0069] For example, in one embodiment, ignoring the voltage value in the startup phase, the initial voltage of the pedal when the sewing machine is running is 1.5V, the maximum voltage is 4V, and when the voltage variation range is 1.5V-2V, the motor speed inside the pedal is fixed at 300 rpm, then the sensitive acceleration value is expressed by the formula:

[0070]

[0071] Among them, a 敏 Expressed as sensitive acceleration value, L 变 is the minimum or middle value of the processing data of the first three processed products, L max It represents the maximum value of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board when the opening of the sewing machine pedal changes the most within the voltage change range. t represents the time point corresponding to the minimum value or the middle value in the processing data of the first three processed products obtained. The corresponding change relationship between the rotation speed and the voltage value after the voltage value exceeds 2V is (5000-300)÷2=2350r / s·v.

[0072] Step S32: automatically adjusting the acceleration of the sewing machine pedal according to the sensitive acceleration value to be not greater than the sensitive acceleration value, thereby limiting the actual acceleration of the sewing machine operated by the unskilled worker to be not greater than the sensitive acceleration value.

[0073] According to the acquired sensitive acceleration value, the acceleration of the sewing machine pedal is automatically adjusted to be not greater than the sensitive acceleration value, that is, the actual acceleration of the pedal of the sewing machine operated by an unskilled worker is less than or equal to the sensitive acceleration value.

[0074] The maximum acceleration of adjusting the sewing machine pedal is introduced in detail in conjunction with the embodiments.

[0075] For example, the processing data of the first three products obtained: L 变1 , L 变2 , L 变3 , arrange the processing data of the first three products in descending order: L 变1 <L 变2 <L 变3 ; Ignoring the voltage value in the startup phase, the initial voltage of the pedal when the sewing machine is running is 1.5V, and the maximum voltage is 4V. When the voltage changes in the range of 1.5V-2V, the motor speed inside the pedal is fixed at 300 rpm.

[0076] When the unskilled worker is a first-level unskilled worker,

[0077]

[0078] Among them, a 敏1 Indicates the sensitive acceleration value of the first-level unskilled worker, L 变1 is the minimum value of the processing data of the first three processed products, L max It represents the maximum value of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board when the opening of the sewing machine pedal changes the most within the voltage change range, and t1 represents the time point corresponding to the minimum value in the processing data of the first three processed products obtained.

[0079] Then, the acceleration of the sewing machine pedal is automatically adjusted to be no greater than the sensitive acceleration value a 敏1 .

[0080] When the unskilled worker is a Level 2 unskilled worker,

[0081]

[0082] Among them, a 敏2 Indicates the sensitive acceleration value of the first-level unskilled worker, L 变2 is the median value of the processing data of the first three processed products, L max It represents the maximum value of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board when the opening of the sewing machine pedal changes the most within the voltage change range, and t2 represents the time point corresponding to the middle value of the processing data of the first three processed products obtained.

[0083] Then, the acceleration of the sewing machine pedal is automatically adjusted to be no greater than the sensitive acceleration value a 敏2 .

[0084] like Figure 4 As shown, in one embodiment, the automatic adaptive sewing machine pedal acceleration method described in the present application also includes step S4.

[0085] Step S4: after automatically adjusting the maximum acceleration of the sewing machine pedal, if the processing data of the sewing machine operated by the operator meets the second preset condition within a preset time period, the acceleration limit on the sewing machine pedal is cancelled.

[0086] Specifically, the second preset condition includes: the number of times that the theoretical acceleration of the sewing machine pedal operated by the operator is greater than the maximum acceleration of the sewing machine pedal after adjustment is greater than a preset number.

[0087] For example, the preset time period is set to 15 minutes and the preset number of times is set to 5 times. That is, after adjusting the maximum acceleration of the sewing machine pedal, within a certain continuous time period of 15 minutes, if the theoretical acceleration of the sewing machine pedal operated by the operator is greater than the adjusted maximum acceleration of the sewing machine pedal for more than 5 times, the acceleration limit on the sewing machine pedal is cancelled.

[0088] Specifically, the processing data of the first three products processed by the operator after a continuous 15-minute period are obtained again, that is, L 变1 ′, L 变2 ′, L 变3 ',at this time,

[0089]

[0090] Among them, L 幅 ′ represents the fluctuation amplitude of the relative position change between the magnetic block inside the pedal and the electronic components on the circuit board of the first three products processed after a continuous 15-minute period, L 波 ′ is the fluctuation value of the maximum-minimum value of the relative position change between the magnetic block and the electronic components after a continuous 15-minute period, L 变1 ' is the relative position change value of the magnetic block inside the pedal and the electronic components on the circuit board when the opening degree of the sewing machine pedal changes the most when processing the first product after a continuous period of 15 minutes.

[0091] When 10% <L 幅 ′≤20%, take L 变1 ′, L 变2 ′, L 变3 Calculate the maximum value of the sensitive acceleration value a in ′ 敏 ′, and adjust the maximum acceleration of the sewing machine pedal to a 敏 ′.

[0092] When L 幅 When ′≤10%, the acceleration restriction on the sewing machine pedal is cancelled and the acceleration demand is responded normally.

[0093] like Figure 5 As shown, the present application provides an automatically adaptive sewing machine pedal acceleration system, comprising:

[0094] The data acquisition module 10 is used to acquire the processing data of the sewing machine pedal corresponding to the first several products processed by the operator.

[0095] The judging module 20 is used to judge whether the operator is an unskilled worker according to the processing data.

[0096] The adjustment module 30 is used to automatically adjust the maximum acceleration of the sewing machine pedal according to the processing data to adapt to the operation of the operator when the operator is an unskilled worker.

[0098] Specifically, the second preset condition includes: the number of times that the theoretical acceleration of the sewing machine pedal operated by the operator is greater than the maximum acceleration of the sewing machine pedal after adjustment is greater than a preset number.
