Description

Technical Field

[0001] The present invention relates to the technical field of carpet production management, in particular to a management system and a management method for carpet production. Background Art

[0002] The carpet production and processing technology is to first weave a carpet embryo through textile threads, then apply the dye on the surface of the formed carpet embryo and put it into a steamer for printing and coloring. After high-temperature fixing, it is washed with water to remove the residual dye and printing auxiliaries on the surface of the printed carpet embryo. Finally, the washed printed carpet embryo is heated again to dry the surface moisture. The secondary heating can not only dry the moisture but also facilitate further shaping and fixing of the dye. Finally, the printed carpet is trimmed and cut to make the carpet we use.

[0003] In the process of washing the carpet for color fixation, the washing intensity and washing time of the water flow need to be adjusted according to the actual situation of the carpet. Since the carpet print is not completely fixed at this time, if the washing intensity is too high and the washing time is too long, the water flow will not only destroy the formed dye, but also cause the carpet to absorb water excessively, become fuzzy and deform, affecting the printing effect. If the washing intensity is too low and the washing time is too short, the carpet cannot be fully cleaned. In order to perform intelligent washing management of the carpet according to the actual size of the carpet during the carpet production process, we propose a carpet production management system and a management method thereof.

[0056] Figure 2 The present invention is a flowchart of a carpet production management method. DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] See also Figure 1-Figure 2 The present invention provides a management system for carpet production, comprising the following modules:

[0060] The water use analysis module obtains the historical water demand value, historical flushing intensity coefficient and historical flushing time coefficient of carpet washing, establishes a historical reference database based on the historical water demand value, historical flushing intensity coefficient and historical flushing time coefficient of carpet washing, obtains the historical flushing intensity reference coefficient and the historical flushing time reference coefficient in the historical reference database through the water demand value of the carpet, and obtains the flushing time and flushing water pressure based on the historical flushing intensity reference coefficient, the historical flushing time reference coefficient, the flushing intensity coefficient and the flushing time coefficient;

[0061] The water washing control module controls the nozzle to reciprocate and wash the carpet according to the washing time and the washing water pressure, and adjusts the movement speed of the nozzle by the washing water pressure and the washing time;

[0062] The quality inspection module obtains the carpet reference sample, compares the washed carpet with the carpet before washing and the carpet reference sample to obtain the print damage value and the cleaning value, and adjusts the flushing intensity coefficient and the flushing time coefficient according to the cleaning value and the print damage value and incorporates them into the historical reference database.

[0063] In this embodiment, the carpet analysis module is used to combine the surface temperature of the carpet with the flushing value to obtain the flushing intensity coefficient, and then the water demand value of the carpet and the flushing value are combined to obtain the flushing time coefficient, so as to facilitate the estimation and calculation of the flushing time and water pressure of the carpet washing according to the actual situation of the carpet, thereby facilitating the subsequent full cleaning of the carpet without damaging the printing on the surface of the carpet, and also helping to avoid excessive water absorption, hairiness and deformation of the carpet that affect the printing effect;

[0064] In this solution, the water analysis module is used to record the historical washing parameters of the carpet to establish a historical reference database, and then the closest situation is captured in the historical reference database according to the actual situation of the carpet washing this time, and then the historical data is combined with the estimated data of the carpet washing this time to obtain the washing time and washing water pressure, so as to further facilitate the subsequent full cleaning of the carpet without damaging the print on the carpet surface;

[0065] In this solution, the washing control module is used to wash the carpet by moving the nozzle reciprocatingly, so as to avoid long-term concentrated washing of one part of the carpet affecting the printing effect. The moving speed of the nozzle is controlled in a targeted manner by the washing water pressure and the washing time, so as to further facilitate the full cleaning of the carpet without damaging the printing on the carpet surface.

[0066] In this solution, the carpet before and after washing is compared with the carpet reference sample through the quality inspection module, the effect of the carpet washing is summarized, and then the washing intensity coefficient and the washing time coefficient are fine-tuned according to the comparison results, and the fine-tuned washing intensity coefficient and the washing time coefficient are included in the database, so as to provide a reference for the subsequent carpet washing, so as to provide more accurate historical reference data for the subsequent carpet washing process, and further facilitate the subsequent carpet washing process to fully clean the carpet without damaging the print on the carpet surface;

[0067] It is worth mentioning that the weight values ​​in this scheme can be obtained through the hierarchical analysis method, and the values ​​of the preset thresholds in this scheme can be obtained through the weight analysis method, which will not be elaborated here.

[0068] In the carpet analysis module, the water demand value of the carpet is obtained, specifically:

[0069] Step 1: Sample one square meter of carpet, inject ten liters of water into the container and put the sampled carpet into the water. Take out the carpet after thirty minutes, record the remaining water volume in the container, and obtain the water absorption saturation of the carpet by subtracting ten liters of water from the remaining water volume.

[0070] Step 2: Use a camera to shoot the carpet to be washed, obtain the length, width and thickness of the carpet, and obtain the volume of the carpet by multiplying the length, height and thickness of the carpet;

[0071] Step 3: Obtain the water absorption saturation of the carpet, obtain the volume of the carpet, and obtain the water demand value of the carpet by multiplying the water absorption saturation of the carpet by the volume of the carpet.

[0072] In this embodiment, one square meter of the carpet to be washed is sampled, the water absorption saturation of the carpet is obtained through an immersion test, and the water absorption saturation of the carpet is combined with the volume of the carpet to obtain a detailed water demand value, thereby facilitating intelligent and precise water washing control of the carpet according to the actual situation of the carpet to be washed.

[0073] In the carpet analysis module, the flushing value of the carpet is obtained, specifically:

[0074] Step 1: Obtain the dye usage of the carpet, set a preset threshold value of the dye usage, and obtain the residual dye amount by subtracting the dye usage from the preset threshold value of the dye usage;

[0075] Step 2: Obtain the heating time and heating temperature of the carpet after printing, and obtain the color fixation strength of the printing by weighted summation of the heating time and the heating temperature;

[0076] Step 3: Use a camera to shoot the carpet to be washed, obtain the number of colors of carpet printing dyes, obtain the types of carpet printing elements, obtain the density of carpet printing lines, and obtain the complexity of printing by weighted summation of the number of colors, the types of elements, and the line density;

[0077] Step 4: Obtain the residual amount of dye, the fixing strength of printing, and the complexity of printing, and obtain the flushing value of the carpet through the residual amount of dye, the fixing strength of printing, and the complexity of printing;

[0078] The flushing value is calculated as follows:

[0079]

[0080] Among them, Cx represents the flushing value, Ci represents the residual dye, Gs represents the fixation strength, Fz represents the printing complexity, δ1, δ2 and δ3 are all weights, 1>δ1>0, 1>δ2>0, 1>δ3>0.

[0081] In this embodiment, the flushing value of the carpet is obtained by combining the residual dye amount, the print fixation strength and the print complexity, so as to facilitate the adjustment of the subsequent water pressure impact strength of the carpet according to the actual situation of the carpet printing, thereby facilitating the full cleaning of the carpet without damaging the print on the carpet surface that has not been completely fixed, and also without causing the carpet to absorb water excessively, become fuzzy and deform, affecting the printing effect.

[0082] In the carpet analysis module, the flushing intensity coefficient is obtained by the surface temperature and flushing value of the carpet, specifically:

[0083] Step 1: Obtain the surface temperature of the carpet, set a preset temperature threshold, compare the surface temperature of the carpet with the preset temperature threshold, if the surface temperature of the carpet is greater than the preset temperature threshold, stop the operation and wait for the carpet to cool down and obtain the surface temperature of the carpet again at a time interval of one minute, if the surface temperature of the carpet is less than the preset temperature threshold, execute step 2;

[0084] Step 2: Obtain the flushing value of the carpet, and obtain the flushing intensity coefficient through the flushing value of the carpet and the surface temperature of the carpet;

[0085] The calculation method of the flushing intensity coefficient is as follows:

[0086]

[0087] Wherein, Qd represents the flushing intensity coefficient, Cx represents the flushing value, Wd represents the surface temperature of the carpet, Wd≥0, θ1 and θ2 are both weights, 1>θ1>0, 1>θ2>0.

[0088] In this embodiment, whether to immediately wash the carpet is determined by the temperature of the carpet surface, which helps to avoid the carpet just out of the steamer having too high a temperature and poor color fixation effect, which may affect the printing effect of the carpet if washed directly, thereby facilitating intelligent control of the time interval between carpet baking and washing.

[0089] In the water use analysis module, the historical flushing intensity reference coefficient and the historical flushing time reference coefficient are obtained from the historical reference database through the water demand value of the carpet, specifically:

[0090] Step 1: Arrange the historical water demand values ​​in the historical reference database in ascending order, obtain the water demand value of the carpet, and subtract all the historical water demand values ​​from the water demand value of the carpet to obtain multiple water demand difference values, and select the two historical water demand values ​​with the smallest water demand difference values ​​as the water demand reference values;

[0091] Step 2: Capture the corresponding historical flushing intensity coefficient and historical flushing duration coefficient in the historical reference database through the two water demand reference values, sum and average the two historical flushing intensity coefficients to obtain the historical flushing intensity reference coefficient, and sum and average the two historical flushing duration coefficients to obtain the historical flushing duration reference coefficient.

[0092] In this embodiment, by referring to the historical data in the historical reference database, it is convenient to subsequently calculate the flushing water pressure and flushing time of the carpet washing according to historical experience and actual conditions, thereby facilitating sufficient cleaning of the carpet while avoiding damage to the print.

[0093] In the water use analysis module, the flushing time and flushing water pressure are obtained according to the historical flushing intensity reference coefficient, the historical flushing time reference coefficient, the flushing intensity coefficient and the flushing time coefficient, specifically:

[0094] Step 1: Obtain historical flushing intensity reference coefficients, obtain flushing intensity coefficients, weight the historical flushing intensity reference coefficients and the flushing intensity coefficients and average them to obtain final flushing intensity coefficients, set a preset flushing water pressure threshold, and obtain flushing water pressure by multiplying the final flushing intensity coefficient by the preset flushing water pressure threshold;

[0095] Step 2: Obtain the historical flushing time reference coefficient, obtain the flushing time coefficient, assign weights to the historical flushing time reference coefficient and the flushing time coefficient and average them to obtain the final flushing time coefficient, set the flushing time preset threshold, and obtain the flushing time by multiplying the final flushing time coefficient by the flushing time preset threshold.

[0096] In this embodiment, the closest situation is captured in the historical reference database based on the actual situation of the carpet washing this time, and the washing time and washing water pressure are obtained by combining the historical data with the estimated data of the carpet washing this time, so as to facilitate the subsequent full cleaning of the carpet without damaging the print on the carpet surface.

[0097] In the water washing control module, the movement speed of the nozzle is adjusted by the washing intensity coefficient and the washing time, specifically:

[0098] Step 1: Obtain the flushing water pressure, set a preset threshold value of the water pressure damage degree, and calculate the quotient of the flushing water pressure and the preset threshold value of the water pressure damage degree. If the quotient result is an integer, the quotient result is used as the number of nozzle steering times. If the quotient result is a non-integer, the integer part of the quotient result plus one is taken as the number of nozzle steering times;

[0099] Step 2: Obtain the maximum one-way moving distance of the nozzle, obtain the number of turns of the nozzle, and obtain the moving distance by multiplying the number of turns of the nozzle by the maximum one-way moving distance of the nozzle;

[0100] Step 3: Get the flushing time, and obtain the moving speed of the nozzle by dividing the movement time by the flushing time.

[0101] In this embodiment, the carpet is washed in a reciprocating manner by moving the nozzle through the washing control module, so as to avoid long-term concentrated washing of one place on the carpet that affects the printing effect. The movement speed of the nozzle is controlled in a targeted manner by the washing water pressure and washing time, thereby facilitating full cleaning of the carpet without damaging the printing on the carpet surface.

[0102] In the quality inspection module, the washed carpet is compared with the carpet before washing and the carpet reference sample to obtain the print damage value and cleaning cleanliness value, specifically:

[0103] Step 1: obtain a carpet reference sample, take a photo of the carpet reference sample with a camera to obtain a sample image, take a photo of the washed carpet with a camera to obtain a post-wash image, obtain the carpet image before washing and mark it as the pre-wash image, perform grayscale processing on the sample image, the pre-wash image and the post-wash image respectively, and mark the low-brightness areas of the grayscale processed sample image, the pre-wash image and the post-wash image respectively to obtain the sample low-brightness area, the post-wash low-brightness area and the pre-wash low-brightness area;

[0104] Step 2: Measure the areas of the low brightness area of ​​the sample, the low brightness area after washing, and the low brightness area before washing respectively. The print damage value is obtained by subtracting the area of ​​the low brightness area of ​​the sample from the area of ​​the low brightness area after washing. The cleaning value is obtained by subtracting the area of ​​the low brightness area before washing from the area of ​​the low brightness area after washing.

[0105] In this embodiment, by marking the areas of low-brightness regions in the sample image after grayscale processing, the image before washing, and the image after washing, and then comparing the sizes of the low-brightness regions, it is convenient to judge the degree of damage to the carpet printing and the degree of cleanliness of the washing, thereby facilitating the subsequent adjustment of the parameters recorded in the historical reference database.

[0106] In the quality inspection module, the flushing intensity coefficient and flushing time coefficient are adjusted according to the cleaning value and the print damage value and incorporated into the historical reference database, specifically:

[0107] Step 1: obtain a cleaning value, obtain a print damage value, set a preset threshold for the cleaning value, set a preset threshold for the print damage value, subtract the cleaning value from the preset threshold for the cleaning value to obtain a cleaning difference, subtract the print damage value from the preset threshold for the print damage value to obtain a print damage difference, and obtain a modification coefficient by weighted summation of the print damage difference and the cleaning difference;

[0108] Step 2: Set the preset threshold of the modification coefficient, set the modification value of the flushing intensity coefficient, set the modification value of the flushing time coefficient, compare the size relationship between the modification coefficient and the preset threshold of the modification coefficient, if the modification coefficient is less than the preset threshold of the modification coefficient, then the flushing intensity coefficient is included in the historical reference database as the final flushing intensity coefficient, and the flushing time coefficient is included in the historical reference database as the final flushing time coefficient; if the modification coefficient is greater than the preset threshold of the modification coefficient, then the flushing intensity coefficient and the modified value of the flushing intensity coefficient are summed as the final flushing intensity coefficient and included in the historical reference database, and the flushing time coefficient and the modified value of the flushing time coefficient are summed as the final flushing time coefficient and included in the historical reference database.

[0109] In this embodiment, by summarizing the effect of the carpet washing, the rinsing intensity coefficient and the rinsing time coefficient are fine-tuned according to the comparison results, and the fine-tuned rinsing intensity coefficient and the rinsing time coefficient are included in the database, so as to provide a reference for subsequent carpet washing, and thus to provide more accurate historical reference data for the subsequent carpet washing process, and further to facilitate the subsequent carpet washing process to fully clean the carpet without damaging the print on the carpet surface.
