Description

  The present invention relates to a cutting oil remote management system, and in particular, extends the life of the water-soluble cutting oil stored in the coolant tank in a state where the water-soluble cutting oil stock solution and water are mixed, and keeps it in a suitable state. The present invention relates to a remote management system for water-soluble cutting oil. The present invention is widely used in the field of using a water-soluble cutting oil, the field of metal processing, and the industrial field that requires liquid agent spoilage management.

  Conventionally, water-soluble cutting oil has been widely used in the metalworking industry and the like because it is excellent in terms of cooling performance and resistance to ignition. However, the water-soluble cutting oil used by diluting the water-soluble cutting oil stock solution several tens to several hundred times with water will be used for a short period of time due to the decay of the water-soluble cutting oil unless proper management is performed. This will cause the liquid to be replaced, leading to an increase in liquid replacement cost and a reduction in equipment operation rate. Moreover, a suitable state cannot be maintained due to a decrease in the concentration of the water-soluble cutting oil, which leads to shortening of the life of the cutting machine tool or the like and deterioration of product quality. For this reason, water-soluble cutting oil in use at the work site is collected at a predetermined frequency, the concentration is measured with a refractometer or the like, the pH is measured with a pH meter or the like, and produced after culturing in a medium for 24 to 48 hours. After measuring the number of viable bacteria by counting the number of colonies, if there is a problem, appropriate measures were taken to manage the water-soluble cutting oil.

  However, in the conventional method, it is necessary for the liquid manager to collect and measure the liquid from all the coolant tanks in the factory at a certain frequency, and the work efficiency is poor. In addition, since dedicated equipment and an analysis room are required to measure the number of viable bacteria, most of them are requested to make a measurement with a water-soluble cutting oil stock solution manufacturer, and the measurement needs to be cultured for 24 to 48 hours. Real-time measurement was practically difficult. In summer, when the room temperature at the work site is likely to rise, the measurement method was practically meaningless because of the high risk of decay in the few days from the collection of the liquid to the determination of the viable cell count results. For this reason, in the conventional method, rapid liquid management cannot be performed, and problems such as an increase in liquid replacement cost due to liquid decay and a decrease in equipment operation rate have occurred.

  Furthermore, when performing liquid management of water-soluble cutting fluid based on the measurement results of each item, it is the intuition and experience of the liquid manager or the oil manufacturer's manager to determine which liquid should be added and how much can be maintained. There was a place that relied on, and it could not be said that proper liquid management was always performed.

  In view of such a situation, several techniques have been disclosed to cope with the above problem. For example, in Patent Document 1, the pH is measured with a pH meter at a predetermined measurement location, the rust prevention property is evaluated using a chip pack for rust prevention evaluation, the number of viable bacteria is measured with a simple viable count device, and A simple liquid management system for a water-soluble cutting fluid that measures oil concentration using a titration device for oil concentration measurement is disclosed. Also, in Patent Document 2, automatic management of water-soluble cutting oil that optimizes the state of coolant liquid by constantly measuring the pH and concentration of water-soluble cutting oil and automatically automatically supplying water-soluble cutting oil stock and water as appropriate. An apparatus is disclosed.

  However, the simple liquid management system for water-soluble cutting fluid of Patent Document 1 can efficiently measure pH, rust-preventing property, viable cell count, and concentration in one place, but the measurement results are specific. No corresponding method is shown, and the measurement of the number of viable bacteria still requires a culture time of 24 to 48 hours, so it cannot be said that the above problem can be addressed. Moreover, in the automatic management apparatus of the water-soluble cutting oil of patent document 2, after automatically measuring the pH and density | concentration of coolant liquid, water-soluble cutting oil stock solution and water are supplied so that it may become optimal pH and density | concentration. The number of viable bacteria in the coolant is not taken into consideration, and it is highly possible that it is too late due to the growth of anaerobic bacteria at the time when an abnormality in pH is detected.

  In the inventions of the above two patent documents, it is basically necessary to be at a site such as a metal cutting factory, and the state of the water-soluble cutting oil when the liquid manager is off-site, on vacation or abroad. Is difficult to optimize. In other words, monitoring items necessary for liquid management of such water-soluble cutting fluid are monitored in real time and constantly, and the measurement results are confirmed remotely. Therefore, there is a demand for a remote management system for water-soluble cutting oil that can extend the liquid life of the water-soluble cutting oil and maintain a suitable state by remotely performing various treatments.

The water-soluble cutting oil measuring unit 1 and the water-soluble cutting oil control unit 2 and the coolant management software 3 communicate with each other via a cloud server 4 which is one of the external servers in a wired or wireless manner.

  The water-soluble cutting oil measuring unit 1 includes a liquid level measuring unit 6 that measures the water level of the coolant tank 5, a viable cell count measuring unit 7 that measures the viable cell count of the water-soluble cutting oil, and the concentration of the water-soluble cutting oil. It has a concentration measuring unit 8 for measuring, a pH measuring unit 9 for measuring the pH of the water-soluble cutting oil, and a communication unit 10 for transmitting each measurement result monitored in real time and constantly to the cloud server 4.

  The water-soluble cutting oil control unit 2 receives a liquid management instruction from the cloud server 4 and inputs a bactericide 20 and a water-soluble cutting oil stock solution (hereinafter also referred to as a cutting stock solution) 21 based on the liquid management instruction. A control unit 12 that performs control, a sterilizing agent replenishing unit 13 that replenishes the coolant tank 5 with a sterilizing agent 20, and a water-soluble cutting oil stock solution replenishing unit (hereinafter also referred to as a stock solution replenishing unit) that replenishes the coolant tank 5 with the cutting stock solution 21. 14), a water replenishing unit 15 that replenishes the coolant tank 5 with water supplied from the water supply source 19, a disinfectant remaining amount measuring unit 16, and a cutting stock solution remaining amount measuring unit 17.

The water replenishing unit 15 has an electromagnetic on-off valve connected to a water supply source 19 such as a water supply, and the electromagnetic on-off valve opens and closes in response to a charging instruction from the control unit 12.

  For example, if the relationship between the number of viable bacteria and the amount of bactericidal agent is examined in advance, the liquid management amount calculation function of the coolant management software 3 can be used to input the bactericidal agent from the measured value of the viable cell count and the capacity of the coolant tank 5. The amount can be calculated. For example, when the pH falls below a predetermined range, the amount of the water-soluble cutting stock solution 21 that increases the concentration of the water-soluble cutting oil to the upper limit of the predetermined range while calculating the water level of the coolant tank 5 is calculated. The pH can be raised to a predetermined range using the alkalinity of the cutting stock solution 21. In this case, the coolant management software 3 also displays that the concentration of the water-soluble cutting oil reaches the upper limit of the predetermined range.

In the procedure P1 of FIG. 2, initial setting of the upper limit value and the lower limit value of the coolant tank water level A, the viable cell count B, the concentration D, the pH value H, the sterilizing agent remaining amount Ap, and the cutting stock solution remaining amount Ad is performed. Transition. In the procedure P2, the coolant tank water level A is measured by the liquid level measuring unit 6 (FIG. 1), and in the procedure P3, it is determined whether or not the coolant tank water level A exceeds the upper limit value A2. When the coolant tank water level A exceeds the upper limit value A2, water-soluble cutting oil management cannot be performed by adding the liquid agent, and the process proceeds to procedure P4. In the procedure P4, the liquid manager's mobile terminal 22 (FIG. 1) is notified / warned that the tank water level has exceeded the upper limit value, and a measure such as pumping out water-soluble cutting oil is urged.

  When the coolant tank water level A does not exceed the upper limit value A2, the process proceeds from the procedure P3 to the procedure P5. In the procedure P5, the viable cell count B is measured by the viable cell count measuring unit 7 (FIG. 1), and it is determined whether or not the viable cell count B exceeds the upper limit value B2 in the procedure P6. When the viable cell count B exceeds the upper limit B2, since the viable cell count level has been reached at which the decay of the water-soluble cutting oil cannot be suppressed, the process proceeds to procedure P7. In the procedure P7, the mobile terminal 22 (FIG. 1) is notified / warned that the viable cell count exceeds the upper limit value, and prompts a total liquid replacement treatment of the water-soluble cutting oil.

  If the viable cell count B does not exceed the upper limit B2 in the procedure P6, the process proceeds to the procedure P8. In procedure P8, it is determined whether the viable cell count B is between the lower limit value B1 and the upper limit value B2. If the viable count B is between the lower limit value B1 and the upper limit value B2, the process proceeds to procedure P9. In step P9, the amount of the sterilizing agent 20 (FIG. 1) is calculated from the viable count B and the capacity of the coolant tank 5 (FIG. 1). The recommended value of the bactericidal replenishment amount is transmitted, and the procedure proceeds to procedure P11. In procedure P11, it is determined whether the liquid manager approves replenishment of the bactericide 20 (FIG. 1). If the liquid manager does not approve the replenishment of the bactericide 20 (FIG. 1), the process proceeds to step P19. If the liquid manager approves, the process proceeds to step P12. In procedure P12, the mobile terminal 22 (FIG. 1) instructs the sterilizing agent replenishing unit 13 (FIG. 1) to replenish the sterilizing agent 20 (FIG. 1), and the sterilizing agent replenishing unit 13 (FIG. 1) (FIG. 1) is replenished with the bactericide 20 (FIG. 1), and the process proceeds to procedure P13.
