Description
本發明係有關於一種液體黏度檢測與控制系統及其方法，尤其係指藉由計算一預設時間內氣動式泵浦的運作次數，以判斷液體黏度是否改變而需添加溶劑的系統與方法。The present invention relates to a liquid viscosity detection and control system and its method, in particular to the system and method for judging whether the viscosity of the liquid needs to be added due to the calculation of the operating times of the pneumatic pump within a predetermined time period.
以往判斷液體黏度都是藉由操作人員以人為的方式判斷，例如傳統在印刷機顏料濃度之檢測與控制技術，大多仰賴具有經驗的操作人員以肉眼觀看方式，主觀判斷印刷出來的成品是否顏色太濃或太淡，若印刷成品上的印刷顏色太濃則憑其經驗於顏料桶加入不定量的溶劑作調整，反之則補充顏料。In the past, the viscosity of the liquid was judged by the operator. For example, the traditional detection and control technology of the pigment concentration in the printing machine mostly relies on the experienced operator to judge whether the printed product is too colorful or not. Thick or too light, if the printing color on the printed product is too thick, adjust it by adding a variable amount of solvent to the paint bucket based on your experience, otherwise, add the pigment.
然而，傳統方法須耗費人力長時間檢查印刷出來的成品，一旦成品印刷出來才發現顏料濃度不適當，只能作廢，且由於操作人員的經驗不同，在不同操作人員調整顏料濃度上，常常造成加入溶劑量不固定而需反覆調整等問題，因此傳統方法具有耗費人力與時間以及判斷不一致之缺點。However, the traditional method requires manpower and a long time to check the printed finished product. Once the finished product is printed, it is found that the pigment concentration is not appropriate and has to be discarded. Due to the different experience of the operators, different operators often adjust the pigment concentration. The amount of solvent is not fixed and needs to be adjusted repeatedly. Therefore, the traditional method has the disadvantages of labor and time consumption and inconsistent judgment.
今，發明人即是鑑於上述現之有顏料濃度檢測與控制方式於實際實施使用時仍具有多處缺失，於是藉由其豐富專業知識及多年之實務經驗所輔佐，而加以改善，並據此研創出本發明。Today, in view of the fact that the above-mentioned existing pigment concentration detection and control methods still have many deficiencies in actual implementation and use, the inventor improved them with the help of his rich professional knowledge and years of practical experience, and based on this Research and create the present invention.

In the following embodiments, the present invention is applied to detect the viscosity of the water-based ink used when printing on a printing machine, so as to prevent the water-based ink from being too thick or too light during the printing process, resulting in uneven density of the water-based ink in the printed product. one.
請參閱第一圖~第三圖，本發明之氣動式泵浦(1)係與一印刷機(7)連接，印刷機(7)的水性墨入口端(71)設有一第三管路(72)以連接到氣動式泵浦(1)，此外印刷機(7)的水性墨出口端(73)也設有一第四管路(74)連接到儲液單元(2)，且此實施例中，儲液單元(2)內存放的為供印刷機(7)於印刷時使用的水性墨，即氣動式泵浦(1)、儲液單元(2)以及印刷機(7)形成一迴路，如第二圖與第三圖所示，氣動式泵浦(1)為一氣動式雙隔膜泵浦，其運作時，可將水性墨從儲液單元(2)經過第一管路(13)與第三管路(72)輸入至印刷機(7)；另，氣動式泵浦(1)之一側藉由氣體管路(31)連接於高壓空氣源(3)，高壓空氣源(3)可供應一定壓氣體給氣動式泵浦(1)，以使氣動式泵浦(1)運作；氣動式泵浦(1)運作時，會藉由空氣流量計(12)偵測排氣口(11)所打出的空氣量，並可藉著空氣量的變化計算氣動式泵浦(1)的運作次數；當儲液單元(2)內的水性墨濃度變高時，水性墨較濃稠，在供應固定壓力氣體的條件下，水性墨較不容易由氣動式泵浦(1)打入印刷機(7)，因此在相同的運作時間內，氣動式泵浦(1)的運作次數會下降；反之，若水性墨濃度降低時，水性墨較稀，在供應固定壓力氣體的條件下，水性墨可以較容易地由氣動式雙隔膜泵浦(1)打入印刷機(7)，因此在相同的運作時間內，氣動式泵浦(2)的運作次數會上升。Please refer to the first figure ~ the third figure, the pneumatic pump (1) of the present invention is connected with a printing machine (7), and the water-based ink inlet port (71) of the printing machine (7) is provided with a third pipeline ( 72) to be connected to the pneumatic pump (1), in addition the water-based ink outlet (73) of the printing machine (7) is also provided with a fourth pipeline (74) to be connected to the liquid storage unit (2), and this embodiment Among them, the water-based ink stored in the liquid storage unit (2) is used by the printing machine (7) during printing, that is, the pneumatic pump (1), the liquid storage unit (2) and the printing machine (7) form a circuit , as shown in the second figure and the third figure, the pneumatic pump (1) is a pneumatic double-diaphragm pump. When it is in operation, the water-based ink can be passed from the liquid storage unit (2) through the first pipeline (13 ) and the third pipeline (72) are input to the printing machine (7); in addition, one side of the pneumatic pump (1) is connected to the high-pressure air source (3) through the gas pipeline (31), and the high-pressure air source ( 3) A certain pressure of gas can be supplied to the pneumatic pump (1) to make the pneumatic pump (1) operate; when the pneumatic pump (1) is operating, the exhaust gas will be detected by the air flow meter (12) The amount of air pumped out of the port (11), and the number of operations of the pneumatic pump (1) can be calculated by the change of the air volume; when the concentration of the water-based ink in the liquid storage unit (2) becomes higher, the water-based ink is thicker Thickness, under the condition of supplying fixed pressure gas, water-based ink is less likely to be driven into the printing machine (7) by the pneumatic pump (1), so in the same operation time, the operation times of the pneumatic pump (1) On the contrary, if the concentration of water-based ink decreases, the water-based ink is thinner, and under the condition of supplying a fixed pressure gas, the water-based ink can be easily injected into the printing machine (7) by the pneumatic double-diaphragm pump (1), Therefore, within the same operating time, the operating frequency of the pneumatic pump (2) will increase.
於實際運作時，會先以第一控制裝置(4)、控制高壓空氣源(1)所提供的氣體壓力，以使高壓空氣源(1)經由氣體管路(31)，提供一定壓的空氣給氣動式泵浦(1)，以設定一定時間區間內、氣動式泵浦(1)的運作次數區間值，並將該運作次數區間值定義為最佳運作次數區間值；此時氣動式泵浦(1)便會從儲液單元(2)吸取水性墨，並供墨給印刷機(7)以進行印刷，而印刷後多餘的水性墨可以透過第四管路(74)回輸到儲液單元(2)。In actual operation, the first control device (4) will be used to control the gas pressure provided by the high-pressure air source (1), so that the high-pressure air source (1) can provide a certain pressure of air through the gas pipeline (31). For the pneumatic pump (1), to set the interval value of the number of times of operation of the pneumatic pump (1) within a certain time interval, and define the interval value of the number of times of operation as the best interval value of the number of times of operation; at this time, the pneumatic pump The pump (1) will absorb the water-based ink from the liquid storage unit (2), and supply the ink to the printing machine (7) for printing, and the excess water-based ink after printing can be returned to the storage unit through the fourth pipeline (74). liquid unit (2).
當印刷機(7)印刷一段時間後，儲液單元(2)中裝盛的水性墨，會因為溶劑蒸發而變黏稠，因此氣動式泵浦(1)的運作次數會開始下降，當空氣流量計(12)偵測到的運作次數低於該最佳運作次數區間值時，控制單元(6)便會藉由調整第一控制裝置(4)，以增加高壓空氣源(3)所提供的氣體壓力，直到該氣動式泵浦(1)的運作次數達到該最佳運作次數區間值；而若之後氣動式泵浦(1)的運作次數高於最佳運作次數區間值時，控制單元(6)便可以再藉由調整第一控制裝置(4)，降低高壓空氣源(3)所提供的氣體壓力，直到該氣動式泵浦(1)的運作次數降低該最佳運作次數區間值。After the printing machine (7) prints for a period of time, the water-based ink contained in the liquid storage unit (2) will become viscous due to the evaporation of the solvent, so the operating frequency of the air pump (1) will begin to decrease. When the air flow When the number of operations detected by the meter (12) is lower than the interval value of the optimal number of operations, the control unit (6) will adjust the first control device (4) to increase the high-pressure air source (3) Gas pressure until the number of operations of the pneumatic pump (1) reaches the interval value of the optimal number of operations; and if the number of operations of the pneumatic pump (1) is higher than the interval value of the optimal number of operations, the control unit ( 6) Then by adjusting the first control device (4), the gas pressure provided by the high-pressure air source (3) can be reduced until the number of operations of the pneumatic pump (1) reduces the interval value of the optimum number of operations.
但是，若當高壓空氣源(3)提供的氣體壓力已經增加到一個預訂的閾值之後、仍無法將氣動式泵浦(1)的運作次數提升到該最佳運作次數區間值，控制單元(6)便會藉由第二控制裝置(5)，從一溶劑補充單元中，運輸水性墨的溶劑到儲液單元(2)中，以稀釋水性墨；稀釋時，是以少量補充的方式，補充一定量的溶劑到儲液單元(2)中，再偵測氣動式泵浦(1)的運作次數，若氣動式泵浦(1)的運作次數已提高到最佳運作次數區間值，則不需要再補充溶劑，但是若氣動式泵浦(1)的運作次數仍不能提高到最佳運作次數區間值，控制單元(6)便會藉由第二控制裝置(5)、於儲液單元(2)中補充溶劑，以維持供給印刷機(7)的水性墨濃度，並使印製的成品上的水性墨不會突然變得很濃或很淡。However, if the gas pressure provided by the high-pressure air source (3) has increased to a predetermined threshold, the number of operations of the pneumatic pump (1) still cannot be increased to the optimal number of operations interval value, the control unit (6 ) will use the second control device (5) to transport the solvent of the water-based ink from a solvent replenishment unit to the liquid storage unit (2) to dilute the water-based ink; Put a certain amount of solvent into the liquid storage unit (2), and then detect the operating times of the pneumatic pump (1). The solvent needs to be supplemented again, but if the operating times of the pneumatic pump (1) still cannot be increased to the optimum operating times interval value, the control unit (6) will use the second control device (5), in the liquid storage unit ( 2) to replenish the solvent to maintain the concentration of water-based ink supplied to the printing machine (7), and to make the water-based ink on the printed finished product not suddenly become very thick or very light.
本發明之另一實施例為，可於設置一電連接於控制單元(6)的警示單元(8)，若當高壓空氣源(3)提供的氣體流量壓力已經增加到一個預訂的閾值之後、仍無法將氣動式泵浦(1)的運作次數提升到該最佳運作次數區間值，控制單元(6)便會藉由警示單元(8)，發出聲音或燈光警示，以提醒操作人員需補充溶劑到儲液單元(2)中，以稀釋水性墨；稀釋時，是以人工操作少量補充的方式，補充一定量的溶劑到儲液單元(2)中，再偵測氣動式泵浦(1)的運作次數，若氣動式泵浦(1)的運作次數已提高到最佳運作次數區間值，則不需要再補充溶劑，但是若氣動式泵浦(1)的運作次數仍不能提高到最佳運作次數區間值，控制單元(6)便會再次藉由警示單元(8)，發出聲音或燈光警示，以提醒操作人員需再次於儲液單元(2)中補充溶劑，以維持供給印刷機(7)的水性墨濃度，並使印製的成品上的水性墨不會突然變得很濃或很淡。Another embodiment of the present invention is that a warning unit (8) electrically connected to the control unit (6) can be provided, and if the gas flow pressure provided by the high-pressure air source (3) has increased to a predetermined threshold, If the number of operations of the pneumatic pump (1) still cannot be increased to the optimal interval value of the number of operations, the control unit (6) will issue a sound or light warning through the warning unit (8) to remind the operator that it is necessary to replenish Put the solvent into the liquid storage unit (2) to dilute the water-based ink; when diluting, add a certain amount of solvent to the liquid storage unit (2) by manually operating a small amount of supplement, and then detect the pneumatic pump (1 ), if the number of operations of the pneumatic pump (1) has been increased to the optimum number of operations interval, there is no need to replenish the solvent, but if the number of operations of the pneumatic pump (1) still cannot be increased to the maximum When the optimal number of operations is reached, the control unit (6) will send out a sound or light warning through the warning unit (8) to remind the operator that the solvent needs to be replenished in the liquid storage unit (2) to maintain the supply of the printing machine (7) The concentration of water-based ink, and make the water-based ink on the printed finished product not suddenly become very thick or very light.
另於本發明之實施例中，尚可設置一電連接於控制單元(1)的紀錄單元(9)，以供紀錄本系統運作時之各項參數數據，供作日後本系統運作設定之用。In addition, in the embodiment of the present invention, a recording unit (9) electrically connected to the control unit (1) can also be provided for recording various parameter data during the operation of the system for future operation setting of the system .
由上述之實施說明可知，本發明與現有技術相較之下，本發明具有以下優點:As can be seen from the above description, compared with the prior art, the present invention has the following advantages:
1.本發明僅需在系統開機時調整設定基準值後，就可藉由系統持續檢測與控制一預設時間內之氣動式泵浦的運作次數，判斷是否加入溶劑於儲液單元中調整液體的黏度，因此本系統係藉由較客觀方式持續檢測與控制液體黏度，可避免人為判斷液體黏濃度時因為個人標準不一致而導致液體黏度判定變異性大之缺失。1. The present invention only needs to adjust the set reference value when the system is turned on, and then the system can continuously detect and control the operation times of the pneumatic pump within a preset time, and judge whether to add solvent to the liquid storage unit to adjust the liquid Therefore, this system continuously detects and controls the viscosity of the liquid in a more objective way, which can avoid the lack of large variability in the determination of liquid viscosity due to inconsistent personal standards when judging the viscosity of the liquid manually.
2.本發明於使用時，操作人員無需長時間檢測儲液單元內的液體黏度，因此可達到節省人力與降低成本之功效。2. When the present invention is in use, the operator does not need to check the viscosity of the liquid in the liquid storage unit for a long time, thus saving manpower and reducing costs.
3.本發明於使用前，可於儲液單元中加入各種已知黏度值之液體，再令系統開機運行一段時間，並記錄系統在不同黏度液體運行下之氣體壓力與氣動式泵浦的運作次數作為樣本值，於日後使用本發明時，僅需比對樣本值、便可即時得知當時系統中液體的黏度值。3. Before using the present invention, various liquids with known viscosity values can be added to the liquid storage unit, and then the system is started to run for a period of time, and the gas pressure and the operation of the pneumatic pump under the operation of liquids with different viscosities can be recorded. The number of times is used as a sample value. When the present invention is used in the future, the viscosity value of the liquid in the system at that time can be known in real time only by comparing the sample values.
綜上所述，本發明之液體黏度檢測與控制系統及其方法，的確能藉由上述所揭露之實施例，達到所預期之使用功效，且本發明亦未曾公開於申請前，誠已完全符合專利法之規定與要求。爰依法提出發明專利之申請，懇請惠予審查，並賜准專利，則實感德便。To sum up, the liquid viscosity detection and control system and method of the present invention can indeed achieve the expected use effects through the above disclosed embodiments, and the present invention has not been disclosed before the application, and it is fully in line with The provisions and requirements of the Patent Law. ￠It is really convenient to file an application for a patent for invention according to the law, and ask for the review and approval of the patent.
