Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of data processing, and in particular relates to a quotation method for a clothing order and a sewing machine with a loss detection device. Background Art
[0002] Currently, the general formula for apparel quotes is as follows: Quoted Price = (Quantity per piece of fabric and accessories, including shrinkage and loss, × Fabric Unit Price + Unit Price of secondary processes like printing and embroidery + Garment Processing Fee) × (1 + Profit Margin %). However, market validation shows that quotes based on this formula have a low accuracy rate. Generally speaking, the cost of fabric and accessories, as well as the price of secondary processes like printing and embroidery, are relatively fixed. Therefore, problems often arise with garment processing fees. Garment processing fees refer to the labor costs required to produce a garment, as well as the associated costs associated with this "labor cost," such as factory management and machine maintenance. Many managers lack a deep understanding of these costs, leading to significant cost accounting errors. Even after multiplying these costs by the required high gross profit margin, they still cannot compensate for the losses caused by omissions and miscalculations during the calculation process, resulting in losses. Therefore, the need to effectively calculate garment processing fees is becoming increasingly important. Summary of the Invention
[0003] The purpose of the present invention is to provide a quotation method for clothing orders and a sewing machine with a loss detection device, so that the quotation for clothing orders can be carried out quickly and accurately.
[0004] The present invention provides a method for quoting a clothing order, which is implemented as follows:
[0005] A method for quoting a clothing order comprises the following steps:
[0006] S101, storing the processing fee per cm of garments in different processes;
[0007] S102, splitting the order garments into process steps according to the fabric and difficulty of the ordered garments;
[0008] S103, counting the total sewing length of each type of garment in the order;
[0009] S104. Determine the garment processing fee for a single piece of clothing using the following formula:
[0010] The processing fee per cm of each process multiplied by the total sewing length of each process and summed up;
[0011] S105. Determine the garment processing fee using the following formula:
[0012] Processing fee for a single garment × total number of orders;
[0013] S106. Based on the garment processing fee in step S105, a quotation for the garment order is given.
[0014] In the above-mentioned quotation method for clothing orders, the ordered clothing can be divided into difficult processes, medium processes and simple processes according to the fabric and difficulty.
[0015] In the aforementioned quotation method for a clothing order, the steps for determining the garment processing fee per cm for each process are as follows:
[0016] S201. Determine employee expenses:
[0017] For each process, select two workstations: Employee A and Employee B. One of the two employees has a higher proficiency, while the other has a lower proficiency.
[0018] Record the number of pieces completed by employee A after a period of production and his salary during this period. Divide employee A's salary by the number of pieces completed to obtain the unit price of each piece completed by employee A.
[0019] Similarly, calculate the unit price of one piece completed by employee B;
[0020] The sum of the unit prices of employee A and employee B completing one piece divided by the total length of the process will give the employee cost per cm of sewing in that process.
[0021] S202. Determine the machine maintenance cost:
[0022] Record the machine maintenance expenses incurred by employee A and employee B in step S201;
[0023] Calculate employee A's machine maintenance cost by dividing employee A's number of pieces to obtain employee A's maintenance fee per piece.
[0024] Calculate employee B's machine maintenance cost by dividing employee B's number of pieces.
[0025] Calculate the machine maintenance cost per cm for this process by summing the maintenance cost per unit for employee A and employee B and dividing it by the total length of the process.
[0026] S203. Determine garment processing costs:
[0027] The sum of the employee cost per cm of the corresponding process and the machine maintenance cost per cm of the corresponding process can be used to obtain the garment processing fee per cm of the corresponding process.
[0028] In the above-mentioned quotation method for clothing orders, if there is little change in the personnel in the factory, all employees in each category are directly used for calculation.
[0029] The sewing machine with a wear detection device of the present invention is implemented as follows:
[0030] A sewing machine with a wear detection device, used to assist in deriving the machine maintenance costs incurred by employees A and B in step S201, respectively, comprises a sewing body, a lifting plate hingedly connected in the middle to the sewing machine body, a presser foot lifting assembly that slides up and down on the sewing machine body, a two-stroke electromagnet provided on the sewing machine body, and a lifting and pressing lever hinged in the middle to the sewing machine body, wherein a connecting rod 1 is hinged on the lifting and pressing lever, one end of the lifting plate is hinged to the connecting rod 1, and the other end of the lifting plate abuts against the lifting and pressing assembly for support, and an end of the lifting and pressing lever away from the connecting rod 1 abuts against the core rod of the two-stroke electromagnet, and the core rod has a first stroke and a second stroke, and the displacement of the second stroke is greater than that of the first stroke. The displacement amount, a target area is provided on the sewing machine body, and a detection device is connected to the lifting and sliding movement of the sewing machine body, and the detection device includes an image acquisition module for collecting image data of parts in the target area of the sewing machine body, and a connecting rod 2 is hinged on the sewing machine body, one end of the connecting rod 2 extends into the detection device for support, and the other end of the connecting rod 2 is located on the moving path of the lifting and pressing assembly, when the double-stroke electromagnet drives the core rod to move to the first stroke, the presser foot lifting assembly moves close to the connecting rod 2 and abuts against the connecting rod 2, and a torsion spring 1 is provided on the sewing machine body, and the torsion spring 1 presses the connecting rod 2 so that the end of the connecting rod 2 close to the presser foot lifting assembly has a tendency to rotate downward.
[0031] By adopting the above technical solution, when using the sewing machine, the core rod moves to the first stroke, the core rod lifts one end of the lifting and pressing lever, the lifting and pressing lever rotates, and the lifting and pressing lever and connecting rod 1 cooperate to drive the presser foot lifting and lifting assembly to move upward close to connecting rod 2 and abut against connecting rod 2; when employee A or employee B finishes using the sewing machine, the core rod enters the second stroke, the presser foot lifting and lifting assembly moves upward close to connecting rod 2 and drives one end of connecting rod 2 to rotate upward, and the other end of connecting rod 2 descends, driving the detection device to descend close to the target area. The degree of parts wear in the target area is recorded by the image acquisition module. When employees A and B use the same machine, the degree of wear of the same batch of parts when used by employees A and B can be determined based on the images collected after employees A and B have finished using the machine, which facilitates the calculation of the machine maintenance costs for employees A and B using the same batch of parts.
[0032] Preferably, the detection device also includes a lifting connecting rod that is lifted and slidably connected to the sewing machine body, a control element provided on the image acquisition module and a photoelectric detection element provided on the sewing machine body, the connecting rod 2 extends into the lifting connecting rod support, the photoelectric detection element is located in the target area, the photoelectric detection element is used to detect whether the target area is covered with fabric, and output a corresponding photoelectric signal based on the detection result, the control element receives the photoelectric signal and compares the received photoelectric signal with a preset signal value, when the photoelectric signal is the same as the preset signal, the control element controls the image acquisition module to capture the image.
[0033] By adopting the above technical solution, when the target area is covered with fabric, the photoelectric detection element outputs a covering photoelectric signal, the covering photoelectric signal received by the control element is different from the preset value, and the image acquisition module does not perform image acquisition; when the fabric in the target area is removed, the photoelectric detection element outputs an uncovered photoelectric signal, the uncovered photoelectric signal received by the control element is the same as the preset value, and the control element controls the image acquisition module to capture the image of the target area, which is conducive to ensuring that the parts are not covered by the fabric in the captured image.
[0034] Preferably, a push switch is provided on the sewing machine body, and the push switch controls the power on and off of the image acquisition module. The push switch is located on the moving path of the second connecting rod. When the push switch is pressed, the power of the image acquisition module is connected.
[0035] By adopting the above technical solution, in actual use, when the detection device descends, the connecting rod will press the switch to power on the image acquisition module, ensuring that the image acquisition module captures the target image after approaching the target area.
[0036] Preferably, an LED light is fixed on the image acquisition module for illuminating the target area.
[0037] By adopting the above technical solution and fixing the LED light on the image acquisition module, on the one hand, it is beneficial to ensure sufficient lighting in the target area during the image acquisition process; on the other hand, it is convenient for employees to clearly identify the thread position during the sewing process, thereby improving work efficiency and product quality.
[0038] The advantages of the present invention compared to the prior art are:
[0039] 1. The present invention can accurately calculate the processing fee of a single garment by taking into account the garment processing fee per centimeter of different processes and the total sewing length of each process. Combined with the total number of garments in an order, the total garment processing fee for the order is obtained, and a reasonable quotation for the garment order is then given. This improves the accuracy and efficiency of quotation for garment orders and avoids losses caused by incorrect quotation.
[0040] 2. When employees A and B use the same machine, the wear and tear of parts from the same batch can be determined based on the images collected after use by employees A and B, facilitating the calculation of machine maintenance costs for employees A and B using the same batch of parts.
[0041] 3. The image acquisition module is controlled by the photoelectric detection element and the control element control signal to collect the image of the target area to prevent the situation in which the fabric covers the parts and the degree of wear of the parts is difficult to observe during the image acquisition process.

[0049] The present invention will be further described below with reference to specific embodiments. Figure 1 —6:
[0050] The present invention provides a method for quoting a clothing order. Figure 1-4 , the quotation method includes:
[0051] Step S101, storing the processing fee per cm of garments in different types of processes;
[0052] Step S102: splitting the order garments into different processes according to the fabric and difficulty of the ordered garments;
[0053] Step S103, counting the total sewing length of each type of order garment process;
[0054] Step S104: Determine the garment processing fee for a single piece of clothing using the following formula:
[0055] The processing fee per cm of each process multiplied by the total sewing length of each process and summed up;
[0056] Step S105: Determine the garment processing fee using the following formula:
[0057] Processing fee for a single garment × total number of orders;
[0058] Step S106: Based on the garment processing fee in step S105, a clothing order quotation is given.
[0059] The present invention can accurately calculate the processing fee of a single piece of clothing by using the processing fee per centimeter of clothing in different types of processes and the total sewing length of each type of process. Combined with the total number of pieces in a clothing order, the total processing fee of the order is obtained, and a reasonable clothing order quotation is then given, thereby improving the accuracy and efficiency of clothing order quotations and avoiding losses caused by incorrect price quotations.
[0060] Further, if Figure 1 As shown, after a factory receives a clothing order, the IE or administrator categorizes all processes involved in the order based on factors such as fabric type and process difficulty. These processes can be classified as difficult, medium, or simple. For example, processes made from thicker or more difficult fabrics often require higher employee wages and are more susceptible to damage to machine needles. These processes are classified as difficult. On the other hand, processes made from common fabrics with simpler processing techniques are classified as simple. This is determined by the garment processing factory based on actual conditions. Note: "Difficult" refers to the classification of processes in a clothing order, which may include multiple processes rather than a single, identical one. The same applies to medium and simple processes.
[0061] Furthermore, the garment processing fee per cm for each process is determined as follows:
[0062] Specifically Figure 2 For example, the clothing ordered is divided into three major categories of processes, namely difficult processes, medium processes and simple processes, and two workstations are selected for each category of processes.
[0063] Step S201: Determine employee expenses:
[0064] Select two workstations for each difficult process: Employee A and Employee B.
[0065] Select two workstations from each medium process: Employee C and Employee D.
[0066] Take a simple process and select two workstations: employee E and employee F;
[0067] Employees A, C, and E have high proficiency, while employees B, D, and F have low proficiency. It's important to note that selecting two employees with different proficiency levels can reduce calculation errors caused by proficiency. In a real factory, if there's little variation in personnel, all employees in each category can be used for calculations, which results in higher accuracy.
[0068] Record the number of pieces completed by employee A after a period of production and his salary during this period. Divide employee A's salary by the number of pieces completed to obtain the unit price of a piece completed by employee A when completing the more difficult process.
[0069] Similarly, calculate the price per piece that employee B would pay when completing the more difficult process;
[0070] like Figure 3 As shown, the total length of the more difficult process is the sum of the length processed by employee A in the more difficult process and the length processed by employee B in the same process.
[0071] like Figure 4 As shown, the labor cost per cm for the more difficult process is calculated as follows:
[0072] The employee cost per cm of the more difficult sewing process can be obtained by summing the unit price of each piece completed by employee A and employee B and dividing it by the total length of the more difficult process.
[0073] Similarly, calculate the unit price of one piece when employee C and employee D complete the medium process.
[0074] The employee cost per cm of sewing in the middle process can be obtained by summing the unit price of employees C and D when completing the middle process and dividing it by the total length of the middle process.
[0075] Similarly, calculate the unit price of one piece when employee E and employee F complete the simple process.
[0076] The employee cost per cm of the simple sewing process can be obtained by summing the unit prices of employees E and F when completing a piece and dividing it by the total length of the simple process.
[0077] Step S202: Determine the machine maintenance cost:
[0078] More difficult process: Record the machine maintenance expenses incurred by employee A and employee B in step S201;
[0079] Calculate employee A's machine maintenance cost by dividing employee A's number of pieces to obtain employee A's maintenance fee per piece.
[0080] Calculate employee B's machine maintenance cost by dividing employee B's number of pieces.
[0081] Sum the maintenance cost per unit of employee A and employee B and divide it by the total length of the more difficult process to calculate the machine maintenance cost per centimeter of the more difficult process.
[0082] Similarly, the machine maintenance cost per cm of the medium process is calculated based on the machine maintenance costs incurred by employees C and D in step S201;
[0083] The machine maintenance cost per cm of the simple process is calculated based on the machine maintenance costs incurred by employees E and F in step S201 .
[0084] S203. Determine garment processing costs:
[0085] The sum of the employee cost per cm of the corresponding process and the machine maintenance cost per cm of the corresponding process can be used to obtain the garment processing fee per cm of the corresponding process, that is:
[0086] The processing fee per cm of garment for the more difficult process = the labor cost per cm of the more difficult process + the machine maintenance cost per cm of the more difficult process.
[0087] The processing fee per cm of garment for medium process = the employee cost per cm of medium process + the machine maintenance cost per cm of medium process.
[0088] The processing fee per cm of garment for simple process = the employee cost per cm of simple process + the machine maintenance cost per cm of simple process.
[0089] Through the above method, the factory accumulates the garment processing fees consumed per cm by different types of processes. When the next order comes, the IE or administrator can split the processes of the new order's clothing by type. After counting the total sewing length of each type of process, the garment processing fee per cm of each type of process is used × the total sewing length of each type of process and summed up. After the sum, the garment processing fee of a single piece of clothing in the order can be obtained. The garment processing fee of the order can be calculated by using the single piece garment processing fee × the total number of pieces in the order.
[0090] The present invention discloses a sewing machine with a wear detection device, referring to Figure 5-6 ,
[0091] Sewing machines with wear detection device, see Figure 5, including a sewing machine body 1, a lifting plate 2, a presser foot lifting assembly 3, a double-stroke electromagnet 4 and a lifting and pressing lever 5. The presser foot lifting assembly 3 includes a lifting rod 31 and a presser foot lifting 32. The lifting rod 31 is connected to the sewing machine body 1 by sliding movement. The inner wall of the sewing machine body 1 fits the outer wall of the lifting rod 31 to limit the lifting rod 31. The presser foot lifting 32 is located below the lifting rod 31 and is fixedly connected to the lifting rod 31. The middle part of the lifting plate 2 is hinged to the sewing machine body 1. The hinge axis of the lifting plate 2 is horizontal. The lifting plate 2 is L-shaped. A contact surface 311 is formed on the lifting rod 31. The end of the lifting plate 2 close to the lifting rod 31 extends into the lifting rod 31 and abuts against the abutment surface 311 from below to support the lifting rod 31. The double-stroke electromagnet 4 and the lifting and pressing lever 5 are both located on the side of the lifting plate 2 away from the lifting rod 31. The two-stroke electromagnet 4 is fixed to the sewing machine body 1 via a connecting plate. The middle portion of the lifting and pressing lever 5 is hingedly connected to the sewing machine body 1. The hinge axis of the lifting and pressing lever 5 is located on the side of the two-stroke electromagnet 4 closest to the lifting rod 31. The hinge axis of the lifting and pressing lever 5 is parallel to the hinge axis of the lifting plate 2 and perpendicular to the distribution direction of the two-stroke electromagnet 4 and the lifting rod 31. The lifting and pressing lever 5 is L-shaped. A second torsion spring 51 is fixed to the sewing machine body 1. The second torsion spring 51 is located above the lifting and pressing lever 5. One end of the second torsion spring 51 presses against the lifting and pressing lever 5, causing the end of the lifting and pressing lever 5 closest to the two-stroke electromagnet 4 to rest against the upper end of the core rod 41 of the two-stroke electromagnet 4. The other end of the lifting and pressing lever 5 is hingedly connected to a first connecting rod 52. The opposite ends of the first connecting rod 52 are respectively hinged to the lifting and pressing lever 5 and the lifting plate 2. The first connecting rod 52 is hinged to the end of the lifting plate 2 away from the abutment surface 311.
[0092] During actual use, the double-stroke electromagnet 4 is energized, and one end of the lifting and pressing lever 5 is lifted up by the core rod 41, and the lifting and pressing lever 5, the connecting rod 52 and the lifting plate 2 drive the lifting rod 31 to rise and lift the presser foot 32.
[0093] The double-stroke electromagnet 4 adopts a double-coil design. By switching the power-on state of different coils, the core rod 41 of the double-stroke electromagnet 4 has a first stroke and a second stroke. The double-stroke electromagnet 4 extends and contracts in the vertical direction. The displacement of the second stroke is greater than the displacement of the first stroke. The first stroke and the second stroke are both located above the double-stroke electromagnet 4.
[0094] When the core rod 41 is in the first stroke or the second stroke, the rotation angle of the lifting and pressing lever 5 lifted by the core rod 41 is different. Through the cooperation between the lifting and pressing lever 5, the connecting rod 52 and the lifting plate 2, the lifting rod 31 and the presser foot 32 are driven to rise to different heights.
[0095] A target area 11 is provided on the sewing machine body 1 , and the presser foot lifter 32 , the feed dog and the needle in the sewing machine body 1 are all located in the target area 11 .
[0096] A second connecting rod 12 is hingedly connected to the sewing machine body 1. The middle portion of the second connecting rod 12 is hinged to the sewing machine body 1, and the hinge axis of the second connecting rod 12 is parallel to the hinge axis of the first connecting rod 52. A detection device 6 is connected to the sewing machine body 1 in a lifting and sliding manner. The detection device 6 is used to detect the degree of wear of parts within the target area 11. The detection device 6 and the lifting rod 31 are located on opposite sides of the hinge axis of the second connecting rod 12. The end of the second connecting rod 12 closest to the detection device 6 supports the detection device 6. The end of the second connecting rod 12 away from the detection device 6 is located above the lifting rod 31, and the end of the second connecting rod 12 away from the detection device 6 is located in the movement path of the lifting rod 31. A torsion spring 11 is fixed to the sewing machine body 1. The torsion spring 11 61 presses against the second connecting rod 12, causing the end of the second connecting rod 12 close to the lifting rod 31 to have a tendency to rotate downward.
[0097] When the core rod 41 is in the first stroke, the upper end of the lifting rod 31 abuts the connecting rod 2 12. When the core rod 41 extends to the second stroke, the upper end of the lifting rod 31 abuts the connecting rod 2 12 to rotate the connecting rod 2, so that the detection device 6 moves downward close to the target area 11.
[0098] With this structure, when employee A or B needs to lift the presser foot lifter 32 during garment production, the core rod 41 of the two-stroke electromagnet 4 moves from its starting position to its first stroke. At this point, the detection device 6 remains above the target area 11, minimizing the impact on garment production. When other employees use their sewing machines or need to change fabrics before making garments, the core of the two-stroke electromagnet 4 enters its second stroke, causing the detection device 6 to move closer to the target area 11. This allows the detection device 6 to capture images of parts within the target area 11, facilitating the assessment of repair costs per employee per piece.
[0099] The detection device 6 includes a lifting connecting rod 62, a control element 63, a photoelectric detection element 64 and an image acquisition module 65. The lifting connecting rod 62 is connected to the sewing machine body 1 by lifting and sliding. The image acquisition module 65 is fixedly connected to the lifting connecting rod 62. The image acquisition module 65 is used to capture an image of the target area 11. The degree of wear of the presser foot lifter 32, the feed dog and the needle in the sewing machine body 1 is determined through the image captured by the image acquisition module 65.
[0100] In the embodiment of the present application, the image acquisition module 65 is a high-resolution industrial camera that uses image processing software (such as OpenCV) to analyze images, identify wear dimensions, and measure the dimensions. The detection results are compared with the initial data to calculate the wear amount.
[0101] A photoelectric detection element 64 is mounted on the sewing machine body 1 and is located within the target area 11 and below the presser foot lifter 32. The photoelectric detection element 64 is used to detect whether the target area 11 is covered with fabric and output a covered photoelectric signal and an uncovered photoelectric signal based on the detection result. A control element 63 is mounted on the image acquisition module 65 and is used to receive the covered photoelectric signal and uncovered photoelectric signal emitted by the photoelectric detection element 64. When the control element 63 receives the covered photoelectric signal, the control element 63 controls the image acquisition module 65 to not capture an image; when the control element 63 receives the uncovered signal, the control element 63 controls the image acquisition module 65 to capture an image.
[0102] After detection by the photoelectric detection element 64, the control element 63 controls the image acquisition module 65 to take pictures, so that the state of the parts can be fully seen, which is conducive to reducing the generation of waste images.
[0103] A push switch 66 is mounted on the sewing machine body 1. This switch is located in the rotational path of the second connecting rod 12 near the end of the lifting rod 31 and above the second connecting rod 12. When the core rod 41 is in the second stroke, the second connecting rod 12 depresses the push switch 66. This switch is used to control the power supply to the image acquisition module 65. Pressing the push switch 66 powers the image acquisition module 65 on, while releasing the push switch powers it off. This helps reduce the occurrence of situations where the control element 63 controls the image acquisition module 65 to capture an image before the image acquisition module 65 approaches the target area 11, thereby reducing waste images and lowering energy consumption.
[0104] An LED light is fixed to the image acquisition module 65 for illuminating the target area 11. Fixing the LED light to the image acquisition module 65 not only facilitates sufficient lighting of the target area 11 during the image acquisition process, but also facilitates employees to clearly identify the threading position during the sewing process, thereby improving work efficiency and product quality.
[0105] The staff can judge the percentage of wear incurred by different employees during processing based on the wear status of the parts in the images captured by the image acquisition module, and obtain the machine maintenance costs incurred by employees A and B in step S201 in the above-mentioned quotation method for a clothing order based on the maintenance costs incurred by the batch of parts multiplied by the percentage of wear incurred by the employee when processing the fabric.
[0106] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
