Technical Field

[0001] The invention relates to the technical field of plate production management, in particular to a multi-color quartz stone plate production and feeding system. Background Art

[0002] Quartz slabs are a new type of stone material that is artificially synthesized from more than 80% quartz crystals, resin and other trace elements. It is mainly pressed by special machines under certain physical and chemical conditions. It can be made into large-sized slabs and customized into different specifications and styles according to customer needs. With the development of the stone processing industry, multi-color quartz slabs are favored by the market for their unique decorative effects and durability. At present, in the production process of multi-color quartz stone slabs, various raw materials required are transported to the mixer according to the corresponding weight ratio according to production needs for mixing to achieve feeding. However, in actual use, it is difficult to realize automatic feeding control and accurately evaluate the accuracy of raw material ratio and raw material mixing effect. Moreover, it is impossible to reasonably judge the operation performance of the corresponding mixing process when the raw material mixing effect is good, which is not conducive to ensuring the quality of the produced quartz stone slabs and reducing the difficulty of operation and management. The degree of automation and intelligence is low; In view of the above technical defects, a solution is now proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-color quartz stone slab production feeding system, which solves the problems that the prior art is difficult to realize automatic feeding control and accurately evaluate the accuracy of raw material ratio and raw material mixing effect, and cannot reasonably judge the operating performance of the corresponding stirring and mixing process when the raw material mixing effect is judged to be good, which is not conducive to ensuring the quality of quartz stone slabs and reducing the difficulty of operation and management, and has low automation and intelligence levels.

[0004] To achieve the above object, the present invention provides the following technical solutions: A multi-color quartz slab production and feeding system, comprising a formula entry module, a feeding control module, a raw material input monitoring module, a ratio accuracy analysis module, a raw material mixing evaluation module and a feeding management center; the management personnel determine the raw material formula based on the information of the quartz slab to be produced, input the raw material formula through the formula entry module, and the formula entry module sends the raw material formula to the feeding control module; the feeding control module obtains the raw materials to be transported based on the raw material formula, controls the valve of the corresponding storage bin to open, and transports the corresponding raw materials to the mixer; After the delivery of various raw materials is completed, the raw material input monitoring module sends the delivery amount of various raw materials to the ratio accuracy analysis module, and the ratio accuracy analysis module analyzes the raw material ratio accuracy and generates a ratio high accuracy signal or a ratio low accuracy signal through analysis. When a ratio high accuracy signal is generated, the feed control module starts the mixer, and when a ratio low accuracy signal is generated, the feed management center issues an early warning. When the mixer finishes mixing various raw materials, the raw material mixing evaluation module samples and detects the materials at several positions in the mixer, and evaluates and analyzes the raw material mixing effect based on the detection results. The module generates a mixing effect abnormality signal or a mixing effect excellent signal through analysis, and sends the mixing effect abnormality signal or the mixing effect excellent signal to the feeding management center. When the feeding management center receives the mixing effect abnormality signal, it issues a corresponding warning.

[0005] Furthermore, the specific analysis process of the ingredient accuracy analysis module is as follows: The delivery volume of the corresponding raw material is obtained, the difference between the delivery volume of the corresponding raw material and the corresponding set standard delivery volume is calculated and the absolute value is taken to obtain the delivery deviation value, and the delivery deviation value is numerically compared with the corresponding preset delivery deviation threshold. If the delivery deviation value exceeds the corresponding preset delivery deviation threshold, the corresponding type of raw material is marked as an abnormal delivery raw material; if an abnormal delivery raw material exists, a low ratio precision signal is generated.

[0006] Furthermore, if there is no abnormal input raw material, a set of preset quality impact weight values ​​is set in advance for each raw material, and the ratio of the input deviation value of the corresponding raw material to the corresponding preset input deviation threshold is marked as the input deviation value, and the input deviation value is multiplied by the corresponding preset quality impact weight value to obtain the input abnormal risk value; And the input risk values ​​of all types of raw materials that need to be transported are summed up to calculate the ratio accuracy influence coefficient, and the ratio accuracy influence coefficient is numerically compared with the corresponding preset ratio accuracy influence coefficient threshold. If the ratio accuracy influence coefficient exceeds the corresponding preset ratio accuracy influence coefficient threshold, a low ratio accuracy signal is generated; if the ratio accuracy influence coefficient does not exceed the corresponding preset ratio accuracy influence coefficient threshold, a high ratio accuracy signal is generated.

[0007] Furthermore, the specific analysis process of the raw material mixing effect evaluation and analysis is as follows: Obtain the content percentage data of the corresponding type of raw material at each position, perform variance calculation on the content percentage data of the corresponding type of raw material at each position to obtain a dispersion disorder value, and compare the content percentage data with the corresponding preset content percentage data range. If the content percentage data is not within the corresponding preset content percentage data range, mark the corresponding position as a biased position of the corresponding type of raw material; Obtain the number of biased positions corresponding to the corresponding type of raw materials and calculate the ratio of it to the total number of sampling and detection positions to obtain the bias performance value, and mark the deviation value of the content percentage data of the biased position compared with the corresponding preset content percentage data range as the bias degree value, and mark the maximum bias degree value corresponding to the corresponding type of raw materials as the bias amplitude value; The raw material fusion coefficient is obtained by numerically calculating the dispersion disorder value, the bias performance value and the bias amplitude value, and the raw material fusion coefficient is numerically compared with the corresponding preset raw material fusion coefficient threshold. If the raw material fusion coefficient exceeds the corresponding preset raw material fusion coefficient threshold, the corresponding type of raw material is marked as abnormal fusion raw material; if there is abnormal fusion raw material, a mixed effect abnormal signal is generated; if there is no abnormal fusion raw material, a mixed effect excellent signal is generated.

[0008] Furthermore, the raw material mixing evaluation module is communicatively connected to the mixing operation judgment module. The raw material mixing evaluation module sends a mixing efficiency signal to the mixing operation judgment module. When the mixing operation judgment module receives the mixing efficiency signal, it conducts a comprehensive analysis of the mixing performance of the corresponding mixing process of the mixer, and generates a mixing operation qualified signal or a mixing operation alarm signal through the analysis. The mixing operation qualified signal or the mixing operation alarm signal is sent to the feeding management center. When the feeding management center receives the mixing operation alarm signal, it issues a corresponding early warning.

[0009] Furthermore, the specific analysis process of the mixed performance comprehensive analysis includes: The number of times the mixed monitoring symbol YL-1 is assigned in the corresponding mixing process is obtained and marked as the mixed monitoring abnormal value, and all the mixed monitoring values ​​in the corresponding mixing process are averaged to obtain the mixed monitoring value, and the mixed monitoring value with the largest value in the corresponding mixing process is marked as the mixed abnormal amplitude value; The mixed meter evaluation value is obtained by numerically calculating the mixed monitoring value, the mixed monitoring meter value and the mixed amplitude value, and the mixed meter evaluation value is numerically compared with the corresponding preset mixed meter evaluation threshold value. If the mixed meter evaluation value exceeds the corresponding preset mixed meter evaluation threshold value, a mixed operation alarm signal is generated; if the mixed meter evaluation value does not exceed the corresponding preset mixed meter evaluation threshold value, a mixed operation qualified signal is generated.

[0010] Furthermore, the mixing operation judgment module is communicatively connected to the mixing monitoring and analysis module, and the mixing monitoring and analysis module monitors the mixing process of the mixer in real time, collects the mixing speed and mixing temperature inside the mixer, and marks the deviation value of the mixing speed compared to the set standard speed as the mixing speed control abnormality value, and marks the deviation value of the mixing temperature compared to the set standard temperature as the mixing temperature control abnormality value; The shaking amplitude of the mixer is collected and marked as the stirring shaking amplitude table value, and the mixing monitoring value is obtained by numerically calculating the stirring speed control value, the stirring temperature control value and the stirring shaking amplitude table value. The mixing monitoring value is numerically compared with the preset mixing monitoring threshold. If the mixing monitoring value exceeds the preset mixing monitoring threshold, the mixing monitoring symbol YL-1 is assigned, and the mixing monitoring symbol YL-1 and all mixing monitoring values ​​in the corresponding mixing process are sent to the mixing operation judgment module.

[0011] Furthermore, the material supply management center is communicated with the operation and control management decision module, and the operation and control management decision module is used to set a management cycle of Q1 days. When the number of days reaches Q1, the material supply automatic control performance for the production of quartz stone slabs within the management cycle is evaluated and analyzed, and a material supply operation control qualified signal or a material supply operation control alarm signal is generated through the analysis, and the material supply operation control qualified signal or the material supply operation control alarm signal is sent to the material supply management center. When the material supply management center receives the material supply operation control alarm signal, it will issue a corresponding warning.

[0012] Furthermore, the specific analysis process of the operation control management decision module is as follows: The control delay time of the feeding control module for all storage silo valves within the management cycle is obtained, and the average of all control delay time is calculated to obtain the valve control delay value; the number of times the low-precision signal of the proportion is generated within the management cycle is obtained and the ratio is calculated with the total number of times of proportioning to obtain the proportion error detection value, and the number of mixing processes corresponding to the mixing effect error signal or the mixing operation alarm signal within the management cycle is obtained and the ratio is calculated with the total number of mixing to obtain the mixing operation error detection value; The operation control management decision value is obtained by numerically calculating the valve control delay value, the ingredient abnormality detection value and the mixed operation abnormality detection value, and the operation control management decision value is numerically compared with the preset operation control management decision threshold. If the operation control management decision value exceeds the preset operation control management decision threshold, a material supply operation control alarm signal is generated; if the operation control management decision value does not exceed the preset operation control management decision threshold, a material supply operation control qualified signal is generated.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the raw material formula is sent to the feeding control module through the formula input module. The feeding control module controls the automatic delivery of various types of raw materials based on the raw material formula. After the delivery of various raw materials is completed, the accuracy of the raw material ratio is analyzed. When a high-precision ratio signal is generated, the mixer is started and operated through the feeding control module. At the end of the mixing, the raw material mixing effect is accurately evaluated and a warning is issued in time, which is conducive to ensuring the quality of the produced quartz stone slabs and reducing the difficulty of operation and management. The degree of automation and intelligence is high; 2. In the present invention, the mixing performance of the corresponding mixing process of the mixer is comprehensively analyzed through the mixing operation judgment module, and the cause investigation and analysis are carried out and corresponding improvement measures are taken when the mixing operation alarm signal is generated to ensure the operation safety and mixing effect of the mixer.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings; Figure 1 This is a system block diagram of Embodiment 1 of the present invention; Figure 2 This is a system block diagram of Embodiment 2 and Embodiment 3 of the present invention. DETAILED DESCRIPTION

[0015] 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.

[0016] Embodiment 1: Figure 1 As shown, a multi-color quartz stone slab production and feeding system proposed by the present invention includes a formula entry module, a feeding control module, a raw material input monitoring module, a ratio accuracy analysis module, a raw material mixing evaluation module and a feeding management center; The manager determines the raw material formula based on the information of the quartz slabs to be produced, and inputs the raw material formula (including the required raw materials and quality information of various types of raw materials) through the formula entry module. The formula entry module sends the raw material formula to the feeding control module, and the feeding of quartz slabs of different colors can be completed according to different raw material formulas; The feeding control module obtains the required raw materials based on the raw material formula. The required raw materials include quartz sand (powder), resin, pigment (the corresponding pigment is used according to the required color of the quartz stone slab), curing agent, coupling agent, etc. It controls the valve of the corresponding storage bin to open to release the corresponding raw materials, and transports the corresponding raw materials to the mixer to realize the automatic transportation of various types of raw materials.

[0017] After the delivery of various raw materials is completed, the raw material input monitoring module sends the actual delivery amount of various raw materials to the ratio accuracy analysis module. The ratio accuracy analysis module analyzes the raw material ratio accuracy and generates a high-ratio accuracy signal or a low-ratio accuracy signal through analysis. When a high-ratio accuracy signal is generated, the feed control module starts the mixer and generates a low-ratio accuracy signal. The feed management center issues an early warning to remind the management personnel to take reasonable measures to avoid affecting the quality of the produced quartz stone slabs due to the batching results not meeting the requirements, which significantly reduces the difficulty of management personnel in operation and management. The specific analysis process of the batching accuracy analysis module is as follows: The delivery volume of the corresponding raw material is obtained, the difference between the delivery volume of the corresponding raw material and the corresponding set standard delivery volume is calculated and the absolute value is taken to obtain the delivery deviation value, and the delivery deviation value is numerically compared with the corresponding preset delivery deviation threshold. If the delivery deviation value exceeds the corresponding preset delivery deviation threshold, it indicates that the delivery volume of the corresponding type of raw material is too much or too little, that is, the delivery volume of the corresponding type of raw material does not meet the requirements, then the corresponding type of raw material is marked as abnormal delivery raw material; if there is abnormal delivery raw material, it indicates that the automatic batching effect is poor, which is not conducive to ensuring the quality of the produced quartz stone slabs, and a low-ratio precision signal is generated.

[0018] Furthermore, if there is no heterogeneous raw material, a set of preset quality impact weight values ​​greater than zero is set for each raw material in advance. It should be noted that the greater the adverse effect of the content deviation of the corresponding type of raw material on the quality of the produced quartz stone slab, the greater the value of the preset quality impact weight value that matches it; The ratio of the input deviation value of the corresponding raw material to the corresponding preset input deviation threshold is marked as the input deviation value, and the input deviation value is multiplied by the corresponding preset quality impact weight value to obtain the input risk value; and the input risk values ​​of all types of raw materials to be transported are summed to obtain the ratio accuracy influence coefficient, wherein the larger the value of the ratio accuracy influence coefficient, the worse the automatic batching effect is, and the less conducive it is to ensure the quality of the produced quartz stone slabs; The ratio accuracy influence coefficient is numerically compared with the corresponding preset ratio accuracy influence coefficient threshold. If the ratio accuracy influence coefficient exceeds the corresponding preset ratio accuracy influence coefficient threshold, it indicates that the automatic batching effect is poor, which is not conducive to ensuring the quality of the produced quartz stone slabs, and a low ratio accuracy signal is generated; if the ratio accuracy influence coefficient does not exceed the corresponding preset ratio accuracy influence coefficient threshold, it indicates that the automatic batching effect is good, which is conducive to ensuring the quality of the produced quartz stone slabs, and a high ratio accuracy signal is generated.

[0019] When the mixer finishes mixing various raw materials, the raw material mixing evaluation module samples and tests the materials at several positions in the mixer, and evaluates and analyzes the raw material mixing effect based on the test results. Through analysis, a mixing effect abnormality signal or a mixing effect excellent signal is generated, and the mixing effect abnormality signal or the mixing effect excellent signal is sent to the feeding management center. When the feeding management center receives the mixing effect abnormality signal, it issues a corresponding warning to remind the management personnel to take reasonable disposal measures for the corresponding materials (such as abandoning the mixed materials, etc.), so as to further reduce the adverse effects on the quality of the produced quartz stone slabs; the specific analysis process of the raw material mixing effect evaluation and analysis is as follows: Obtaining the content percentage data of the corresponding type of raw materials at each position, performing variance calculation on the content percentage data of the corresponding type of raw materials at each position to obtain a dispersion disorder value. The larger the dispersion disorder value, the more uneven the distribution of the corresponding type of raw materials; The content percentage data is compared with the corresponding preset content percentage data range. If the content percentage data is not within the corresponding preset content percentage data range, it indicates that the content of the corresponding type of raw material at this position does not meet the requirements, and the corresponding position is marked as a biased position of the corresponding type of raw material; Obtain the number of biased positions corresponding to the corresponding type of raw materials and calculate the ratio of it to the total number of sampling and detection positions to obtain the bias performance value, and mark the deviation value of the content percentage data of the biased position compared with the corresponding preset content percentage data range as the bias degree value, and mark the maximum bias degree value corresponding to the corresponding type of raw materials as the bias amplitude value; The raw material fusion coefficient RX is obtained by numerically calculating the dispersion disorder value YM, the bias performance value SW and the bias amplitude value TF through the formula RX=wq×YM+uy×SW+pk×TF; wherein wq, uy, and pk are preset weight coefficients with values ​​greater than zero, and the larger the value of the raw material fusion coefficient RX, the worse the distribution performance of the corresponding type of raw materials after stirring and mixing; The raw material fusion coefficient RX is numerically compared with the corresponding preset raw material fusion coefficient threshold. If the raw material fusion coefficient RX exceeds the corresponding preset raw material fusion coefficient threshold, it indicates that the distribution performance of the corresponding type of raw materials after stirring and mixing is poor, and the corresponding type of raw materials is marked as abnormal fusion raw materials; If there are abnormal fusion raw materials, it means that the mixing effect is poor, which is not conducive to ensuring the quality of the produced quartz stone slabs, and a mixing effect abnormal signal is generated; if there are no abnormal fusion raw materials, it means that the mixing effect is good, which is conducive to ensuring the quality of the produced quartz stone slabs, and a mixing effect excellent signal is generated.

[0020] Embodiment 2: Figure 2As shown, the difference between this embodiment and the first embodiment is that the raw material mixing evaluation module is communicatively connected to the mixing operation judgment module, the raw material mixing evaluation module sends a mixing efficiency signal to the mixing operation judgment module, and the mixing operation judgment module performs a comprehensive analysis of the mixing performance of the corresponding mixing process of the mixer when receiving the mixing efficiency signal, and generates a mixing operation qualified signal or a mixing operation alarm signal through the analysis; And the qualified mixed operation signal or mixed operation alarm signal is sent to the feeding management center. When the feeding management center receives the mixed operation alarm signal, it issues a corresponding warning to remind the management personnel to conduct cause investigation and analysis and take corresponding improvement measures to ensure the operation safety and mixing effect of the mixer and further reduce the management difficulty of the management personnel; the specific analysis process of the comprehensive analysis of the mixing performance is as follows: The number of times the mixed monitoring symbol YL-1 is assigned in the corresponding mixing process is obtained and marked as the mixed monitoring abnormal value, and all the mixed monitoring values ​​in the corresponding mixing process are averaged to obtain the mixed monitoring value, and the mixed monitoring value with the largest value in the corresponding mixing process is marked as the mixed abnormal amplitude value; The mixed monitoring value FY, the mixed monitoring value WP and the mixed amplitude value XS are numerically calculated by the formula HW=tu×FY+(ng×WP+rq×XS) / 2 to obtain the mixed table evaluation value HW; wherein tu, ng, and rq are preset weight coefficients with values ​​greater than zero, and the larger the value of the mixed table evaluation value HW is, the worse the mixing performance of the corresponding mixing process is overall, and the more abnormal the operation of the mixer is; The mixing table evaluation value HW is numerically compared with the corresponding preset mixing table evaluation threshold. If the mixing table evaluation value HW exceeds the corresponding preset mixing table evaluation threshold, it indicates that the mixing performance of the corresponding mixing process is generally poor and the operation of the mixer is relatively abnormal, then a mixing operation alarm signal is generated; if the mixing table evaluation value HW does not exceed the corresponding preset mixing table evaluation threshold, it indicates that the mixing performance of the corresponding mixing process is generally good and the operation of the mixer is relatively normal, then a mixing operation qualified signal is generated.

[0021] Furthermore, the mixing operation judgment module is communicatively connected to the mixing monitoring and analysis module, which monitors the mixing process of the mixer in real time, collects the stirring speed and stirring temperature inside the mixer, marks the deviation value of the stirring speed compared to the set standard speed as the stirring speed control abnormality value, and marks the deviation value of the stirring temperature compared to the set standard temperature as the stirring temperature control abnormality value; The shaking amplitude of the mixer is collected and marked as the stirring shaking amplitude table value, and the stirring speed control value TW, the stirring temperature control value YF and the stirring shaking amplitude table value HS are numerically calculated by the formula GY=(ew×TW+up×YF+hu×HS) / 3 to obtain the mixing monitoring value GY; wherein ew, up, and hu are preset weight coefficients with values ​​greater than zero, and the larger the value of the mixing monitoring value GY is, the more abnormal the real-time mixing performance of the mixer is in general; The mixing monitoring value GY is numerically compared with the preset mixing monitoring threshold. If the mixing monitoring value GY exceeds the preset mixing monitoring threshold, indicating that the real-time mixing performance of the mixer is generally abnormal, the mixing monitoring symbol YL-1 is assigned, and the mixing monitoring symbol YL-1 and all mixing monitoring values ​​in the corresponding mixing process are sent to the mixing operation judgment module, which can not only monitor the mixing process of the mixer in real time and effectively, but also accurately analyze the abnormal conditions of the mixer, and provide data support for the analysis process of the mixing operation judgment module to ensure the accuracy of its analysis results.

[0022] Embodiment 3: Figure 2 As shown, the difference between this embodiment and the first and second embodiments is that the material supply management center is connected to the operation control management decision module in communication, and the operation control management decision module is used to set the management cycle of days Q1, preferably, Q1=15; when the number of days reaches Q1, the material supply automatic control performance for the production of quartz stone slabs within the management cycle is evaluated and analyzed, and a material supply operation control qualified signal or a material supply operation control alarm signal is generated through analysis; And the qualified signal of material supply and control or the alarm signal of material supply and control are sent to the material supply management center. When the material supply management center receives the alarm signal of material supply and control, it will issue a corresponding warning, which can reasonably analyze and accurately feedback the automatic control performance of material supply for quartz stone slab production during the management cycle, and strengthen the subsequent material supply control supervision when the alarm signal of material supply and control is generated, so as to ensure the safety, stability and efficiency of the subsequent material supply process, and the intelligent degree is high; the specific analysis process of the operation control management decision module is as follows: Obtain the control delay time of the feed control module for all storage silo valves within the management period (i.e., the interval between the time when the feed control module issues a command and the time when the corresponding storage silo valve is opened / closed), and calculate the average of all control delay times to obtain the valve control delay value; And the number of times the low-ratio precision signal is generated within the management cycle is obtained and the ratio is calculated with the total number of times the ingredients are mixed within the management cycle to obtain the ingredient precision error detection value, and the number of mixing processes corresponding to the mixing effect error signal or the mixing operation alarm signal within the management cycle is obtained and the ratio is calculated with the total number of mixing within the management cycle to obtain the mixing operation error detection value; The valve control delay value PX, the batching fine abnormality detection value NW and the mixed operation abnormality detection value GP are numerically calculated by the formula XR=sy×PX+tg×NW+rm×GP to obtain the operation control management decision value XR; wherein, sy, tg, rm are preset weight coefficients with values ​​greater than zero, and the larger the value of the operation control management decision value XR, the worse the overall performance of the automatic control of the material supply for the production of quartz stone slabs during the management cycle; The operation and control management decision value XR is numerically compared with the preset operation and control management decision threshold. If the operation and control management decision value XR exceeds the preset operation and control management decision threshold, it indicates that the automatic feeding control performance for the production of quartz stone slabs during the management cycle is generally poor, and a feeding operation and control alarm signal is generated; if the operation and control management decision value XR does not exceed the preset operation and control management decision threshold, it indicates that the automatic feeding control performance for the production of quartz stone slabs during the management cycle is generally good, and a feeding operation and control qualified signal is generated.

[0023] The working principle of the present invention is as follows: when in use, the raw material formula is sent to the feeding control module through the formula entry module. The feeding control module controls the valve of the corresponding storage bin to open based on the raw material formula to release the corresponding raw materials, thereby realizing the automatic delivery of various types of raw materials. After completing the delivery of various raw materials, the ratio accuracy analysis module analyzes the raw material ratio accuracy. When a high-precision ratio signal is generated, the mixer is started and operated through the feeding control module to avoid affecting the quality of the produced quartz stone slabs due to the batching results not meeting the requirements. When the mixer finishes mixing various raw materials, the raw material mixing evaluation module samples and detects the materials at several positions in the mixer, and evaluates and analyzes the raw material mixing effect based on the detection results. When a mixing effect abnormality signal is generated, reasonable disposal measures are taken for the corresponding materials, thereby further reducing the adverse effects on the quality of the produced quartz stone slabs, significantly reducing the difficulty of operation and management for management personnel, and having a high degree of automation and intelligence.
