[0054] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. The embodiments described are only a part of the embodiments of the present invention, rather than 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.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0057] Figure 1 The flow chart of the method of the present invention is as follows:

[0058] In one embodiment of the present invention, the formula uploaded by the R&D department is received through the cloud intranet, and the production department retrieves the formula according to the product demand and obtains the rubber material ratio and data according to the actual output; specifically, the R&D department uploads the production formula information and operation data from the cloud network, and the cloud network stores the formula and operation data in the cloud after receiving the production task. After the production department receives the production task, it logs in to the cloud network to retrieve the production task formula and operation process number information. At the same time, the cloud will calculate the amount of formula rubber according to the production task, and the production department retrieves the material accordingly. At the same time, when the R&D department and the production department operate on the cloud network, the cloud network will record the operation instructions and content, and record the operator and operation time, and register the operator's face or fingerprint when logging in; the glue making and mixing process in the tape production process is completed through this embodiment, and the data of each department is allocated and the operation process is recorded through the cloud, so as to promote the strict implementation of operation specifications between departments, make the operation process reasonable and well-founded, realize standardized production, and review the production process afterwards to stably ensure the quality of glue making.

[0059] In one embodiment of the present invention, the rubber warehouse is located through cloud data, the rubber data in the location warehouse is identified and distinguished, and the distinguished rubber is accurately taken according to the formula information, so as to complete the material taking step in the rubber making process; in conventional rubber storage, the same type of rubber will be centrally stacked and stored, but the batches, components, proportions, models, and sizes of the same type of rubber are all different. Based on the formula information and quantity in the previous embodiment, the stored rubber is accurately identified, and the material taking equipment automatically takes the material in the rubber warehouse. In this way, the rubber is accurately identified, and the rubber is made in full accordance with the rubber making process provided by the R&D department, thereby reducing the quality fluctuations caused by manual experience in rubber making, and prompting the R&D department to implement R&D tasks.

[0060] According to one embodiment of the present invention, the feeding amount is decomposed to feed in sections, and the rubber material is introduced into the reactor in batches after the feeding distribution is completed; thereby, the feeding step in the rubber making process is realized, and the feeding of the reactor is accurately planned according to the rubber making output and the capacity range of the reactor, so as to ensure the same reaction ratio each time, reduce the incomplete utilization rate of the rubber material in the production process, and reduce the fluctuation of the product quality caused by the secondary use of the rubber material. At the same time, accurate feeding reduces the waste caused by excessive production of rubber material, thereby achieving the purpose of accurate feeding in this embodiment.

[0061] In one embodiment of the present invention, the rubber material is heated and stirred in a reactor, and the reaction conditions are monitored. By monitoring the stirring speed and the temperature of the reactor, the rubber liquid is introduced into the glue tank after sufficient reaction. Specifically, the production department executes the glue making according to the process specified by the R&D department, and monitors the execution data and reaction conditions in real time through monitoring data, so as to realize the industrial environment simulation laboratory production process, so that the quality of industrial glue making is consistent with the laboratory production quality, and the reactor can make glue according to the predetermined standard.

[0062] In one embodiment of the present invention, the reactor is self-cleaned after the glue making reaction is completed, and a new glue making instruction is executed after drying. In actual production, it is extremely important to self-clean the reactor and glue tank in time after the reaction production. Timely cleaning can prevent the glue residue from drying and reacting with the subsequent glue making process or changing the concentration, prevent the subsequent production of glue quality fluctuations, save cleaning time and energy consumed during cleaning, and reduce cleaning difficulty and cleaning costs.

[0063] In one embodiment of the present invention, a rubber warehouse is located through cloud data, the rubber data in the warehouse is identified and differentiated, and the differentiated rubber is accurately taken according to the formula information, including:

[0064] First, by retrieving the historical data of rubber entering the warehouse, tracking the rubber positioning coordinate data, and obtaining the actual position coordinates of the rubber, it is convenient for rubber management and data inventory. Specifically, when the rubber is put into the warehouse, the warehouse is divided into n areas, each area represents a type of rubber, and the rubber is stacked according to batches, specifications, and models in a single area. The stacking position and quantity in a single area are divided twice and recorded in the rubber entry data, realizing the synchronous management of rubber making and warehouse management, and is suitable for large-scale fully automated or small-scale manual operation scenarios.

[0065] Then, by identifying the rubber packaging mark image and text data on the actual position coordinates of the rubber, the rubber that meets the production standard model is screened out; specifically, before each rubber is put into storage, the size and thickness of the rubber packaging, the model, name, composition, concentration marks on the packaging, etc. will be scanned and registered. During the scan, the mark surface will be entered, and the image of the mark surface with a 45-degree deflection in multiple directions will be entered. When retrieving, the rubber category will be matched first, and the rubber area will be determined. In addition, the material packaging component concentration batch data will be retrieved according to the material data, and scanned and compared with the actual packaging. When the scan comparison result is consistent with the entered data, the rubber will be picked. This real-time example is suitable for mechanical operations and manual supervision work scenarios.

[0066] After that, the rubber packaging specifications are allocated by output and reactor capacity to obtain the rubber dosage specifications so that the unsealed rubber can be fully utilized. Specifically, the selected rubber is matched according to the scale, output and reactor capacity. Suppose the output is C, and the rubber scale is A1, A2, A3...A n The existence of various scales enables the configuration of rubber materials to be matched and planned according to the inventory rubber materials. In addition, the number of various scales is a1, a2, a3...a n , the rubber scale A1 is the minimum scale, A2 is twice the minimum scale, and the same goes for A n is n times the minimum size;

[0067] a1A1+a2A2+a3A3+......a n A n ≥C,

[0068] C-(a1A1+a2A2+a3A3+......a n A n )≤A X ,

[0069] A X The smallest rubber material in the current library;

[0070] Therefore, the rubber scale is matched according to the target rubber output. Reasonable rubber distribution reduces waste in rubber production, and the scale distribution satisfies single or multiple dumping.

[0071] Finally, the rubber packaging data is monitored through the sampling device, and other rubber mixed in the rubber pile is removed to obtain accurate rubber of various specifications. Specifically, in the final stage of material collection, the rubber is quickly scanned again to identify the text data, picture information and packaging specifications on the rubber packaging, and identified according to the preset rubber requirements. When there is an information mismatch or the specification requirements exceed the rubber quantity, an early warning is issued, the non-compliant rubber is removed, and the rubber that exceeds the specification quantity is placed until the total amount of rubber reaches the demand and production is carried out according to the rubber process.

[0072] In one embodiment of the present invention, the material is fed in sections by decomposing the feeding amount, and the rubber material is introduced into the reactor in batches after the feeding distribution is completed, including:

[0073] First, by comparing the reactor capacity and adhesive output, the feeding is planned according to the reactor capacity to obtain the feeding plan; specifically, the minimum reactor capacity S is set. min and the maximum amount S max , the number of reactors is L. For the convenience of production, the capacity of each reactor is the same. The cost of each reactor is M, and the cost includes the reaction time t0, the reaction power consumption is Q, Q includes the heating power consumption Q1 and the stirring power consumption Q2, and the cleaning consumption W, W includes the cleaning power consumption Q3, the cleaning liquid consumption Y and the cleaning time t1. In order to reduce the reaction cost under the premise of quality, in order to avoid setting the reactor capacity too low, the number of reactor production furnaces L meets

[0074] L=C / S, where (S min +S max ) / 2≤S≤S max ,

[0075] The production cost of the reactor is D, D = M * L,

[0076] Assume the cost coefficient is β, as the content of the reactor varies, M = β*M max

[0077] Where M = d*t0+Q1+Q2+Q3+Y+d*t1,

[0078] d is the production cost per unit time this month,

[0079] When production cost D = D min When the number of reactors is rounded, L = L min

[0080] Then, the total weight of the reactor and the materials is monitored by a weight sensor, and a threshold value is set for the total weight. When the weight threshold value is reached, the feed opening valve is controlled; specifically, the total weight of the reactor and the added materials is monitored, and the threshold value is set to 80% of the standard weight of the reactor. When the threshold monitoring range is reached, the feed opening valve control is opened, and the opening and closing time of the valve is controlled according to the feeding speed;

[0081] Finally, the feeding opening valve is controlled to perform multi-stage throttling control on the rubber material feeding to complete the planned rubber material precise feeding. Specifically, the normal opening and closing of the opening valve is recorded as the minimum feeding unit K. When the feeding end is about to be reached, the weight of the unfed material is monitored, and the opening valve is adjusted multiple times in advance to make the unfed amount an integer multiple of the minimum feeding unit K. Generally, the unfed material is controlled to be less than 16 times of K. Taking the opening and closing of 1S as an example, the end of precise feeding is completed within 16S, thereby controlling the opening valve to open and close the feeding port multiple times to complete precise feeding.

[0082] In one embodiment of the present invention, the rubber material is heated and stirred by a reaction kettle, the reaction conditions are monitored, and the rubber solution is introduced into a rubber tank after sufficient reaction, including:

[0083] First, the reactor and the rubber tank are tested for self-cleaning before the rubber is introduced. After cleaning, the final self-cleaning liquid is retained for data analysis. The data analysis is physical analysis or chemical analysis. Physical analysis is to measure the volume and weight through sensors and register the density. Chemical analysis is liquid component content analysis. Generally, the tail cleaning liquid is tested to see whether the cleaning liquid contains glue or rubber components. This is used as the initial self-cleaning liquid data value. The initial self-cleaning liquid data is retained to compare with the cleaning liquid value after subsequent cleaning, so as to determine whether the cleaning process is qualified.

[0084] Then, the glue making data is retrieved through the cloud network, and the glue is added and stirred according to the glue making data, and the reaction temperature and stirring speed are monitored, and the reaction changes are regulated in time to obtain the output glue liquid;

[0085] Finally, the uniformity and viscosity of the output glue are tested. If the test meets the standard, the glue is introduced into the production glue tank to obtain qualified glue. Specifically, the upper, middle and lower layers of glue in the reactor are randomly selected for density testing. If the density test is consistent or the density difference is 3%, it is considered as the uniformity compliance range. This is used as the uniformity compliance standard. When the uniformity meets the standard, the viscosity is tested. The test method is the viscosity cup method in GB / T2794-2022 "Determination of Adhesive Viscosity". If the test meets the viscosity data range, it is stored or introduced into the glue tank for production; if it does not meet the viscosity test data, the glue is exported and saved, the production steps are checked, the reactor is cleaned and dried, and then the material is fed again for testing and production. After the uniformity meets the standard, the viscosity is tested. If the viscosity is the same, it means that the equipment needs maintenance, and the equipment maintenance frequency and investment are increased. If the viscosity still does not meet the qualified range, feedback is sent to the cloud server, and then the R&D and technical department will test the production parameter process. In addition, each time the glue is made, regardless of whether the product is produced, 3 meters of product glue volume and production data will be retained for sample storage and query.

[0086] In one embodiment of the present invention, the same type of glue is continuously reacted through a reactor, and the reactor is self-cleaned after the reaction is completed, and a new glue making instruction is waited after drying. Specifically, after the self-cleaning process is completed, the self-cleaning data value is detected and compared with the initial self-cleaning liquid data value in the previous embodiment, and the self-cleaning process is completed if the comparison is consistent; if the comparison is inconsistent, the cleaning is continued until the cleaning liquid detection data value does not change for two consecutive times, and the self-cleaning process is completed; wherein, a cleaning liquid collection device is provided at the waste outlet of the reactor, which is used to detect the cleaning liquid data and determine whether the cleaning is complete; in addition, whether the reactor is cleaned is detected by a light detection device, and the reflected light waves in the reactor are collected by the light detection device. In the case of complete cleaning, the light wave deflection curve is a continuous and uniform curve, and there will be no sharp turns. The abnormal light wave deflection curve indicates that there is glue residue on the inner wall of the reactor, which affects the deflection of the light and produces a regular curve inconsistent with the cleaning state, thereby judging that a secondary cleaning is required; the cleaning liquid is selected according to the type of glue making, generally a cleaning agent that can dissolve grease, or a cleaning agent that has a good cleaning effect on water-based substances and does not react adversely with the glue.

[0087] One embodiment of the present invention is a tape glue making monitoring system, the system comprising:

[0088] The batching module is used to receive the formula uploaded by the R&D department through the cloud intranet. The production department retrieves the formula according to product demand and obtains the rubber material ratio and data according to the actual output. Specifically, the R&D department uploads the production formula information and operation data from the cloud network. The cloud network receives the formula and operation data and stores them in the cloud. After receiving the production task, the production department logs in to the cloud network to retrieve the production task formula and operation process information. At the same time, the cloud will calculate the amount of formula rubber according to the production task, and the production department retrieves the material accordingly. At the same time, when the R&D department and the production department operate on the cloud network, the cloud network will record the operation instructions and content, and record the operator and operation time. At the same time, the operator’s face or fingerprint is registered when logging in. The rubber preparation process in the tape production process is completed through this embodiment. By allocating data from various departments and recording the operation process on the cloud, departments are urged to strictly implement operation specifications, and the operation process is reasonable and well-founded, so as to achieve standardized production and stably ensure the quality of rubber production.

[0089] The material fetching module is used to locate the rubber warehouse through cloud data, identify and distinguish the rubber data in the location warehouse, and accurately fetch the differentiated rubber according to the formula information; in conventional rubber storage, the same type of rubber will be centrally stacked and stored, but the batches, ingredients, proportions, models, and sizes of the same type of rubber are all different. Based on the formula information and quantity in the previous embodiment, the stored rubber is accurately identified, and the material fetching equipment automatically fetches the material in the rubber warehouse. In this way, the rubber is accurately identified, and the rubber is made in full accordance with the rubber making process provided by the R&D department, reducing the quality fluctuations caused by manual experience in rubber making, and prompting the R&D department to implement R&D tasks.

[0090] The feeding module is used to feed in sections by decomposing the feeding amount, and introduce the rubber into the reactor in batches after completing the feeding distribution; thereby realizing the feeding steps in the rubber making process, and accurately planning the feeding of the reactor according to the rubber making output and the capacity range of the reactor, so as to ensure the same reaction ratio each time, reduce the incomplete utilization rate of the rubber in the production process, and reduce the fluctuation of the product quality caused by the secondary use of the rubber. At the same time, accurate feeding reduces the waste caused by excessive production of rubber, thereby achieving the purpose of accurate feeding in this embodiment.

[0091] The reaction module is used to heat and stir the rubber material through the reactor, monitor the reaction conditions, and introduce the rubber liquid into the glue tank after sufficient reaction; the production department executes the glue making according to the process specified by the R&D department, and monitors the execution data and reaction conditions in real time through monitoring data, so as to realize the industrial environment simulation laboratory production process, so that the quality of industrial glue making is consistent with the laboratory production quality, and then the reactor can make glue according to the predetermined standard.

[0092] The cleaning module is used to perform self-cleaning of the reactor after the glue making reaction is completed, and execute new glue making instructions after drying. It is extremely important to perform self-cleaning of the reactor and glue tank in time after the reaction production. Timely cleaning can prevent the glue residue from drying and reacting with the subsequent glue making process or changing the concentration, prevent the subsequent production of glue quality fluctuations, save cleaning time and energy consumed during cleaning, and reduce cleaning difficulty and cleaning costs.

[0093] In one embodiment of the present invention, the material taking module comprises:

[0094] The positioning module is used to retrieve the historical data of rubber entering the warehouse, track the rubber positioning coordinate data, and obtain the actual position coordinates of the rubber; it is convenient for rubber management and data inventory; specifically, when the rubber is entering the warehouse, the warehouse is divided into n areas, each area represents a type of rubber, and the rubber in a single area is stacked according to batches, specifications, and models. The stacking position and quantity in a single area are divided twice and recorded in the rubber entry data, realizing the synchronous management of rubber making and warehouse management, and is suitable for large-scale fully automated or small-scale manual operation scenarios.

[0095] The recognition module is used to identify the image and text data of the rubber material packaging mark on the actual position coordinates of the rubber material, and screen out the rubber material that meets the production standard model; before each rubber material is put into storage, the size and thickness of the rubber material packaging, the model, name, composition, concentration mark, etc. on the packaging will be scanned and registered. During the scanning, the mark surface will be entered, and the image of the mark surface with a 45-degree deflection in multiple directions will be entered. When retrieving, the rubber category will be matched first, and the rubber area will be determined. In addition, the material packaging component concentration batch data will be retrieved according to the material data, and scanned and compared with the actual packaging. When the scan comparison result is consistent with the entered data, the rubber material will be picked. This real-time example is suitable for mechanical operations and manual supervision work scenarios.

[0096] The allocation module is used to allocate the rubber packaging specifications according to the output and reactor capacity, obtain the rubber dosage specification arrangement, and make full use of the unsealed rubber; specifically, the selected rubber is matched according to the scale, output and reactor capacity. Suppose the output is C, and the rubber scale is A1, A2, A3...A n The existence of various scales enables the configuration of rubber materials to be matched and planned according to the inventory rubber materials. In addition, the number of various scales is a1, a2, a3...a n , the rubber scale A1 is the minimum scale, A2 is twice the minimum scale, and the same goes for A n is n times the minimum size;

[0097] a1A1+a2A2+a3A3+......a n A n ≥C,

[0098] C-(a1A1+a2A2+a3A3+......a n A n )≤A X ,

[0099] A X The smallest rubber material in the current library;

[0100] Therefore, the rubber scale is matched according to the target rubber output. Reasonable rubber distribution reduces waste in rubber production, and the scale distribution satisfies single or multiple dumping.

[0101] The sampling inspection module is used to sample the allocated rubber packaging, remove other rubber mixed in the rubber pile, and obtain rubber of multiple specifications. In the final stage of material collection, the rubber is quickly scanned again to identify the text data, picture information and packaging specifications on the rubber packaging, and identify according to the preset rubber requirements. When there is an information mismatch or the specification requirements exceed the rubber quantity, an early warning is issued, the non-compliant rubber is removed, and the rubber that exceeds the specification quantity is placed until the total amount of rubber reaches the demand and production is carried out according to the rubber process.

[0102] In one embodiment of the present invention, the feeding module comprises:

[0103] The feeding planning module is used to compare the reactor capacity and adhesive output, plan the feeding according to the reactor capacity, and obtain the feeding plan; set the minimum reactor quantity Smin and the maximum reactor quantity Smax, the number of reactors is L, and for the convenience of production, the capacity of each reactor is the same. The cost of each furnace is M, and the cost includes the reaction time t0, the reaction power consumption is Q, Q includes heating power consumption Q1 and stirring power consumption Q2, and the cleaning consumption W, W includes cleaning power consumption Q3, cleaning liquid consumption Y and cleaning time t1. In order to meet the quality premise and reduce the reaction cost, in order to avoid setting the reactor capacity too low, the number of reactor production furnaces L meets

[0104] L=C / S, where (Smin+Smax) / 2≤S≤Smax,

[0105] The production cost of the reactor is D, D = M * L,

[0106] Assume the cost coefficient is β, as the content of the reactor varies, M = β*Mmax

[0107] Where M = d*t0+Q1+Q2+Q3+Y+d*t1,

[0108] d is the production cost per unit time this month,

[0109] When the production cost D=Dmin, the number of reactors is rounded up, L=Lmin.

[0110] The weight warning module is used to monitor the total weight of the reactor and the materials, set a threshold for the total weight, and control the feed opening valve when the weight threshold is reached; monitor the total weight of the reactor and the added materials, set the threshold to 80% of the standard weight of the reactor, and open the feed opening valve control when the threshold monitoring range is reached, and control the opening and closing time of the valve according to the feeding speed;

[0111] The precise feeding module is used to control the feeding opening valve to perform multi-stage throttling control on the rubber feeding to achieve precise rubber feeding. The normal opening and closing of the opening valve is recorded as the set minimum feeding unit K. When the feeding end is about to be reached, the unfed weight is monitored and the opening valve is adjusted multiple times in advance to make the unfed amount an integer multiple of the minimum feeding unit K. Generally, the unfed amount is controlled below 16 times of K, thereby controlling the opening valve to open and close the feeding port multiple times to complete precise feeding.

[0112] In one embodiment of the present invention, the reaction module comprises:

[0113] The pre-cleaning module is used to perform self-cleaning tests on the reactor and the glue tank before the introduction of the glue material. After cleaning, the final self-cleaning liquid is retained for analysis to obtain the initial self-cleaning liquid data value; the data analysis is physical analysis or chemical analysis. The physical analysis is to measure the volume and weight through sensors and register the density. The chemical analysis is a liquid component content analysis. Generally, the tail cleaning liquid is tested to see whether the cleaning liquid contains glue or glue components. This is used as the initial self-cleaning liquid data value. The initial self-cleaning liquid data is retained for comparison with the cleaning liquid value after subsequent cleaning, so as to determine whether the cleaning process is qualified.

[0114] The heating and stirring module is used to retrieve the glue making data, execute the glue making data to heat and stir the glue, monitor the reaction temperature and stirring speed, and obtain the output glue liquid; retrieve the glue making data through the cloud network, add and stir the glue according to the glue making data, monitor the reaction temperature and stirring speed, and adjust the reaction changes in time to obtain the output glue liquid.

[0115] The glue detection module is used to detect the uniformity and viscosity of the output glue. If the test meets the standard, the glue is introduced into the production glue tank to obtain qualified glue. Randomly extract the glue in the upper, middle and lower layers of the reactor for density testing. If the density test is consistent or the density difference is 3%, it is considered as the uniformity compliance range. This is used as the uniformity compliance standard. If the uniformity meets the standard, the viscosity is tested. The test method is the viscosity cup method in GB / T2794-2022 "Determination of Adhesive Viscosity". If the test meets the viscosity data range, it is stored or introduced into the glue tank for production; if it does not meet the viscosity test data, the glue is exported and saved, the production steps are checked, the reactor is cleaned and dried, and then the material is fed again for testing and production. After the uniformity meets the standard, the viscosity is tested. If the viscosity is the same, it means that the equipment needs maintenance, and the frequency and investment of equipment maintenance are increased. If the viscosity still does not meet the qualified range, feedback is sent to the cloud server, and then the R&D and technical department will test the production parameter process. In addition, each time the glue is made, regardless of whether the product is good or not, 3 meters of product glue volume and production data will be retained for sample storage and query.

[0116] In one embodiment of the present invention, the cleaning module comprises:

[0117] The cleaning comparison module is used to detect the self-cleaning data value and compare it with the initial self-cleaning liquid data value after the self-cleaning process is completed. If the comparison is consistent, the self-cleaning process is completed;

[0118] The cleaning update module is used to continue cleaning when there is inconsistency between the cleaning data before and after, until the cleaning liquid detects that the data value has not changed for two consecutive times, thus completing the self-cleaning process.

[0119] After the self-cleaning process is completed, the self-cleaning data value is detected by the cleaning comparison module and compared with the initial self-cleaning liquid data value in the previous embodiment. If the comparison is consistent, the self-cleaning process is completed; if the comparison is inconsistent, the cleaning is continued by the cleaning update module until the cleaning liquid detection data value does not change for two consecutive times, and the self-cleaning process is completed; wherein, a cleaning liquid collection device is provided at the waste outlet of the reactor, which is used to detect the cleaning liquid data and determine whether the cleaning is complete; in addition, whether the reactor is cleaned is detected by a light detection device, and the reflected light in the reactor is collected by the light detection device. In the case of complete cleaning, the light wave deflection curve is a continuous and uniform curve, and there will be no sudden turns. An abnormal light wave deflection curve indicates that there is glue residue on the inner wall of the reactor, which affects the deflection of the light and produces a regular curve inconsistent with the cleaning state, thereby judging that a secondary cleaning is required; the cleaning liquid is selected according to the type of glue making, generally a cleaning agent that can dissolve grease, or a cleaning agent that has a good cleaning effect on aqueous substances and does not react adversely with the glue. The cleaning module is used to analyze and compare the cleaning liquid before and after the reaction to confirm that there are no impurities in the glue-making environment in the reactor before and after cleaning. At the same time, the auxiliary light detection device detects that there is no residue in the glue, ensuring that there are no impurities in the glue-making environment next time. At the same time, the inspection speed is fast and the cleaning is timely, avoiding the impact of manual entry into the reactor for inspection on human health.

[0120] In this article, when it comes to numerical ranges, unless otherwise specified, the above numerical ranges are considered continuous and include the minimum and maximum values ​​of the range, as well as every value between such minimum and maximum values. Further, when a range refers to an integer, every integer between the minimum and maximum values ​​of the range is included. In addition, when multiple ranges are provided to describe features or characteristics, the ranges can be combined. In other words, unless otherwise specified, all ranges disclosed herein should be understood to include any and all subranges included therein.

[0121] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
