Description

Technical Field

[0001] The present invention relates to the technical field of carpet production management, and particularly 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 with textile threads, then apply dyes on the surface of the formed carpet embryo and put it into a steaming box for printing and coloring. After high-temperature color fixation, the residual dyes and printing auxiliaries on the surface of the printed carpet embryo are removed by water washing. Finally, the water-washed printed carpet embryo is reheated to dry the surface moisture. The reheating can not only dry the moisture but also facilitate further shaping and color fixation of the dyes. Finally, the printed carpet is trimmed and cut to make the carpet we use.

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

[0058] Please refer to Figures 1-2 , the present invention provides a management system for carpet production, including the following modules:

[0064] In this solution, the water analysis module records the historical carpet washing parameters to establish a historical reference database. Then, based on the actual situation of the carpet being washed this time, the closest situation is captured in the historical reference database. By combining the historical data with the estimated data of this carpet washing, the flushing duration and flushing water pressure are obtained, which further facilitates subsequent thorough cleaning of the carpet without damaging the printing on the carpet surface;

[0065] In this solution, the water washing control module performs reciprocating water washing with the nozzle moving on the carpet, thus avoiding the influence on the printing effect caused by long-term concentrated flushing of a certain area of the carpet. The moving speed of the nozzle is purposefully controlled by the flushing water pressure and flushing duration, which further facilitates thorough cleaning of the carpet without damaging the printing on the carpet surface;

[0066] In this solution, the quality inspection module compares the carpet before and after flushing with the carpet reference sample, summarizes the effect of this carpet washing, then fine-tunes the flushing intensity coefficient and flushing duration coefficient according to the comparison result, and incorporates the fine-tuned flushing intensity coefficient and flushing duration coefficient into the database, which further facilitates providing reference for subsequent carpet washing, and further facilitates providing more accurate historical reference data during subsequent carpet washing, and further facilitates thorough cleaning of the carpet without damaging the printing on the carpet surface during subsequent carpet washing;

[0067] It is worth mentioning that the weight values in this solution can be obtained through the analytic hierarchy process, and the preset threshold values in this solution can be obtained through the weight analysis method, which will not be elaborated here.

[0068] Obtain the water demand value of the carpet in the carpet analysis module, specifically:

[0069] Step 1: Take a one-square-meter sample of the carpet, inject 10 liters of water into a container, put the sampled carpet into the water, take out the carpet after 30 minutes, record the remaining water volume in the container, and obtain the water absorption saturation of the carpet by subtracting the remaining water volume from 10 liters;

[0070] Step 2: Use a camera to take pictures of the carpet to be washed, obtain the length, width and thickness of the carpet, and obtain the carpet volume 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, by taking a one-square-meter sample of the carpet to be washed, obtaining the water absorption saturation of the carpet through the immersion test, and then combining the water absorption saturation of the carpet with the volume of the carpet to obtain the detailed water demand value of the carpet, which facilitates intelligent and precise water washing control of the carpet according to the actual situation of the carpet to be washed.

[0073] Obtain the flushing value of the carpet in the carpet analysis module, specifically as follows:

[0074] Step 1: Obtain the dye dosage of the carpet, set a preset threshold for the dye dosage, and obtain the dye residue by subtracting the dye dosage from the preset threshold of the dye dosage;

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

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

[0077] Step 4: Obtain the dye residue, obtain the printing color fixation strength, obtain the printing complexity, and obtain the flushing value of the carpet based on the dye residue, the printing color fixation strength, and the printing complexity;

[0078] The calculation method of the flushing value is specifically as follows:

[0079]

[0080] Among them, Cx represents the flushing value, Ci represents the dye residue, Gs represents the color fixation strength, Fz represents the printing complexity, and 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 dye residue, the printing color fixation strength, and the printing complexity, so as to facilitate adjusting the subsequent water pressure impact strength of the carpet according to the actual situation of the carpet printing, and further facilitate cleaning the carpet fully without damaging the unfixed printing on the carpet surface, and also prevent the carpet from being overly water-absorbed, fluffing, and deforming, which affects the printing effect.

[0082] Obtain the flushing intensity coefficient through the surface temperature and the flushing value of the carpet in the carpet analysis module, specifically as follows:

[0083] Step 1: Obtain the surface temperature of the carpet, set a preset temperature threshold, compare the size relationship between the surface temperature of the carpet and 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 one-minute intervals. 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 specifically as follows:

[0088] In this embodiment, it is determined whether to immediately wash the carpet with water through the temperature of the carpet surface, which is beneficial to avoiding the poor color fixation effect directly due to the too high temperature of the carpet just taken out of the steaming box and directly washing with water, which affects the printing effect of the carpet, and further facilitating the intelligent control of the time interval between carpet baking and washing.

[0089] In the water usage analysis module, the historical flushing intensity reference coefficient and the historical flushing duration reference coefficient are obtained through the water demand value of the carpet in the historical reference database, specifically as follows:

[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, subtract the water demand value of the carpet from all the historical water demand values respectively to obtain multiple water demand differences, and select the two historical water demand values with the smallest water demand differences 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 duration of carpet washing based on historical experience and actual conditions, and further facilitate the full cleaning of the carpet while avoiding damage to the printing.

[0093] In the water usage analysis module, the flushing duration and flushing water pressure are obtained based on the historical flushing intensity reference coefficient, historical flushing duration reference coefficient, flushing intensity coefficient, and flushing duration coefficient, specifically as follows:

[0094] Step 1: Obtain the historical flushing intensity reference coefficient, obtain the flushing intensity coefficient, sum and average the weighted historical flushing intensity reference coefficient and the flushing intensity coefficient to obtain the final flushing intensity coefficient, set the preset threshold of the flushing water pressure, and obtain the flushing water pressure by multiplying the final flushing intensity coefficient by the preset threshold of the flushing water pressure;

[0095] Step 2: Obtain the historical flushing duration reference coefficient, obtain the flushing duration coefficient, perform weighted summation and averaging on the historical flushing duration reference coefficient and the flushing duration coefficient to obtain the final flushing duration coefficient, set the flushing duration preset threshold, and obtain the flushing duration by multiplying the final flushing duration coefficient by the flushing duration preset threshold.

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

[0097] In the water washing control module, the moving speed of the nozzle is adjusted by the flushing intensity coefficient and the flushing duration. Specifically:

[0098] Step 1: Obtain the flushing water pressure, set the water pressure damage degree preset threshold, divide the flushing water pressure by the water pressure damage degree preset threshold. If the quotient result is an integer, the quotient result is used as the nozzle turning times. If the quotient result is a non-integer, take the integer part of the quotient result plus one as the nozzle turning times;

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

[0100] Step 3: Obtain the flushing duration, and obtain the moving speed of the nozzle by dividing the moving distance by the flushing duration.

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

[0102] In the quality inspection module, the water-washed carpet is compared with the carpet before water washing and the carpet reference sample respectively to obtain the printing damage value and the cleaning cleanliness value. Specifically:

[0103] Step 1: Obtain the carpet reference sample, take a photo of the carpet reference sample by the camera to obtain the sample picture, take a photo of the water-washed carpet by the camera to obtain the post-washing picture, obtain the picture of the carpet before water washing and mark it as the pre-washing picture, perform gray-scale processing on the sample picture, the pre-washing picture and the post-washing picture respectively, and mark the low-brightness areas of the gray-scale processed sample picture, pre-washing picture and post-washing picture respectively to obtain the sample low-brightness area, the post-washing low-brightness area and the pre-washing low-brightness area;

[0104] Step 2: Measure the areas of the low-brightness region of the sample, the low-brightness region after washing, and the low-brightness region before washing respectively. Obtain the printing damage value by taking the difference between the area of the low-brightness region of the sample and the area of the low-brightness region after washing, and obtain the cleaning cleanliness value by taking the difference between the area of the low-brightness region before washing and the area of the low-brightness region after washing.

[0105] In this embodiment, by marking the areas of the low-brightness regions in the sample picture after gray-scale processing, the picture before washing, and the picture after washing, and then comparing the sizes of the low-brightness region areas, it is convenient to judge the damage degree of the carpet water-washed printing and the cleaning cleanliness degree, and further convenient to adjust the parameters recorded in the historical reference database subsequently.

[0106] In the quality inspection module, adjust the flushing intensity coefficient and the flushing duration coefficient according to the cleaning cleanliness value and the printing damage value and incorporate them into the historical reference database. Specifically:

[0107] Step 1: Obtain the cleaning cleanliness value, obtain the printing damage value, set the cleaning cleanliness value preset threshold, set the printing damage value preset threshold, take the difference between the cleaning cleanliness value and the cleaning cleanliness value preset threshold to obtain the cleaning cleanliness difference, take the difference between the printing damage value and the printing damage value preset threshold to obtain the printing damage difference, and obtain the modification coefficient by weighted summation of the printing damage difference and the cleaning cleanliness difference;

[0108] Step 2: Set the modification coefficient preset threshold, set the flushing intensity coefficient modification value, set the flushing duration coefficient modification value, compare the size relationship between the modification coefficient and the modification coefficient preset threshold. If the modification coefficient is less than the modification coefficient preset threshold, take the flushing intensity coefficient as the final flushing intensity coefficient and incorporate it into the historical reference database, and take the flushing duration coefficient as the final flushing duration coefficient and incorporate it into the historical reference database. If the modification coefficient is greater than the modification coefficient preset threshold, sum the flushing intensity coefficient and the flushing intensity coefficient modification value as the final flushing intensity coefficient and incorporate it into the historical reference database, and sum the flushing duration coefficient and the flushing duration coefficient modification value as the final flushing duration coefficient and incorporate it into the historical reference database.

[0109] In this embodiment, by summarizing the effect of this carpet water-washing, then fine-tuning the flushing intensity coefficient and the flushing duration coefficient according to the comparison result, and incorporating the fine-tuned flushing intensity coefficient and the flushing duration coefficient into the database, it is convenient to provide a reference for subsequent carpet water-washing, and further convenient to provide more accurate historical reference data during the subsequent carpet water-washing process, and even more convenient to fully clean the carpet without damaging the printing on the carpet surface during the subsequent carpet water-washing process.
