Description

  The present invention is in contact with a fluid having a certain property, such as cleaning and sterilizing operations of fluid handling equipment such as bovine milking machines and food manufacturing apparatuses, and surface treatment / coating operations in the manufacture of workpieces. The present invention relates to a device for automatically determining the progress of work and its quality in a fluid work process in which equipment maintenance and workpiece processing are performed, and more particularly to a fluid work monitoring device that uses a plurality of different fluids.

  In the milking machine, before and after the milking operation, washing is performed by flowing washing water such as water and acidic / alkaline washing liquid through the milking line in a predetermined order or circulating the inside of the bulk cooler. In a normal washing procedure, milk components are first washed away by first rinsing with room temperature water or lukewarm water. Next, the dirt that is difficult to dissolve is removed by sequentially performing decomposition cleaning of fat by circulation cleaning with an alkaline cleaning liquid and removal of inorganic substances by acid. Finally, rinse with water or lukewarm water to wash away the cleaning solution. A sterilization step using a bactericidal solution may be further performed before milking.

For example, in the vacuum piping type milking machine described in Japanese Patent Application Laid-Open No. 9-56288 shown in FIG. The milking unit is suspended at the connection port 84 provided in the milk collection pipe 83 passing above the cleaning tank 80 and the tip of each teat cup 85 is used as the cleaning liquid in the cleaning tank 80. By soaking, a cleaning liquid circulation circuit is formed from the washing tank 80 via the teat cup 85, milk claw 86, milk collection pipe 83, receiver jar 87, and breast feeding pump P. Then, the milk feeding pump P is driven to forcibly circulate the cleaning liquid, and the milk collection pipe 83 and the milking unit are automatically cleaned. At the time of completion of washing or flush washing, the drain valve 88 provided on the discharge side pipe of the breast feeding pump is opened, and the returned water and washing liquid are automatically discharged.
JP-A-9-56288

  In washing a milking machine's bulk cooler, it is known to operate a washing pump to circulate a washing liquid / sterilizing liquid inside a tank and perform automatic washing. For example, as shown in FIG. 8, the system configuration at the time of cleaning the bulk cooler is provided with a cleaning pump P and a cleaning liquid supply device 70 in a drain pipe 91 of the bulk cooler 90, and the bulk cooler passes through the cleaning pipe 92 from the cleaning pump P. A circulation circuit for the cleaning liquid to the nozzle 93 at the top 90 is formed. Then, by driving the cleaning pump P while rotating the distribution blade 94, the cleaning liquid is evenly distributed inside the bulk cooler 90 and automatically cleaned. At the time of completion of washing or flush washing, the drain valve 95 provided on the downstream side of the washing pump is opened, and the returned water and washing liquid are automatically discharged.

  In the manufacture of machine parts and the like, surface treatment and coating may be performed by immersing a workpiece in a predetermined electrolyte solution. In this case as well, a plurality of fluid operations are performed such as cleaning with alkali or acid prior to surface treatment or the like, or cleaning with pure water after processing.

  In determining the quality of a fluid work consisting of multiple processes, it was necessary to determine the quality of the work using judgment criteria according to the process while taking into account the progress of the work. The determination is made based on a process signal received from an external device that controls the fluid operation, such as a milking machine control device, an automatic washing device, or an automatic detergent supply device. Therefore, when additional settings are made for existing control devices and cleaning devices, it is necessary to set the communication interface and rewrite the program, so it is not possible to easily add a pass / fail judgment function for the cleaning process. A new investment was unavoidable. In addition, when the user can select automatic / manual as in the cleaning / sterilization process, there is a problem that it is difficult for the operator to manage the process himself / herself.

In the detergent supply apparatus described in Japanese Patent Application Laid-Open No. 2008-154470, in the detergent supply apparatus configured to individually store each detergent in a tank and sequentially supply the detergent to the milking machine, a water level sensor that determines a necessary amount of the detergent in the detergent tank; A detergent sensor (electrical conductivity sensor, capacitance sensor, etc.) that determines the type of detergent is provided, and the control unit of the detergent supply device stores these outputs in advance at a predetermined timing after the start of each cleaning process. Compared with, the type and amount of the stored detergent and the like are confirmed, and the result is displayed on the display unit. However, this apparatus checks the amount of detergent in the detergent tank and the type of detergent, and does not directly check the cleaning liquid that actually circulates in the piping.
JP 2008-154470 A

  Therefore, according to the present invention, the determination of each process of the fluid work including a plurality of processes can be uniquely determined in a stand-alone state without being based on a process signal from an external device such as a milking machine control device or an automatic cleaning device. It is an object of the present invention to provide a monitoring means such as a rational cleaning and sterilization process that can be easily added to an existing control device or cleaning device.

  The invention according to claim 1 is a fluid work monitoring device for judging the quality of work performed by a fluid that is being executed by another external device, wherein the control part, the recording means, and a predetermined circulation path of the cleaning liquid are provided. And at least one sensor for detecting the state of the fluid provided facing the part, and the recording means includes a type feature of the work process by the fluid executed by the external device in advance and a work process used for pass / fail judgment. A predetermined reference value corresponding to the type is stored, and the control unit compares and observes the output change of all or any of the sensors over time with the type characteristics of the work process, and the result is currently performed. A process type determining means for uniquely determining a type of a work process by a fluid without using a signal from an external device, and a work process in which all or any output of the sensor is used for the quality determination Work process pass / fail judgment means for independently judging pass / fail of the work process without using a signal from an external device depending on whether or not a state satisfying a predetermined reference value according to the type has continued for a certain period of time. The above problem is solved by a fluid work monitoring device characterized by the above.

  As a sensor for detecting the state of the fluid used in the present invention, a water quality (fluid quality) sensor such as a temperature sensor, an electrical conductivity sensor, or a pH sensor can be used, depending on the nature of the work performed on the fluid. Various things can be used in combination. Observing the change in the output of the sensor over time refers to determining the process type while taking into account the transition of the output so far along with the current output of the sensor. Record the order and type characteristics of each work process (threshold value of each sensor output for determining the work process), call a reference value indicating the type characteristics of the work process to be performed next time from the recording means, By repeatedly comparing with the output of the sensor, the type of work process currently being performed is determined and stored in the recording means. Therefore, even in a fluid work consisting of a plurality of processes, the progress of the work process can be determined without using an input from the control device of the work process, and an appropriate type feature can be called to make a pass / fail determination.

  Whether or not the state satisfying the reference value used for pass / fail judgment has continued for a certain period of time is determined by whether or not the state where the sensor output satisfies the reference value is repeated for a certain period of time, or whether the state appears a certain number of times during the measurement period This can be done by judging. The fixed time may be a fixed value or a different value for each process. However, when the value is different, it is preferably stored in the recording means as a part of the reference value.

  In the fluid work monitoring device of the present invention, it is possible to determine by itself what the current process is in consideration of the output of the temperature sensor / fluid quality sensor, and then by integrating the time during which the temperature / fluid quality satisfying the standard is accumulated. Since the quality of the current process is judged, the quality of washing can be determined independently without communication with external equipment such as a milking machine control device, automatic washing device, etc. It is possible to use the automatic monitoring function of fluid work.

  The invention according to claim 2 solves the above problem by the fluid work monitoring device according to claim 1, wherein the work process using the fluid includes a cleaning process. For example, maintenance of food production equipment and cleaning steps before and after surface treatment of machine parts and the like correspond to this. Preferably, the fluid work monitoring device includes one or more water quality (fluid quality) sensors, such as an electrical conductivity sensor and a pH sensor, which output detection signals that vary depending on the types and concentrations of temperature sensors and detergents. For example, the recording means stores reference values for temperature, fluid quality, and duration used for distinction between cleaning processes and quality determination, and the control unit outputs all or any one of the temperature sensor and the fluid quality sensor. Compared with the reference value, the cleaning process self-determination means that self-determines the currently performed cleaning process based on the result, and the state where the output of all or one of the temperature sensor and the fluid quality sensor satisfies the standard has continued for a certain period of time. Whether or not the cleaning process is good is determined depending on whether or not the cleaning process is good. When monitoring the milking machine cleaning device, the liquid temperature is maintained at about 35-50 ° C. in the rinsing / sterilization process and rises to about 60 ° C. in the cleaning process, so it is determined which process is currently in process. By using the determination of the detergent by the fluid quality sensor that is effective for the process together with the process determination based on the liquid temperature, it is possible to determine the progress of the cleaning operation and its quality.

  Preferably, by providing both the electrical conductivity sensor and the pH sensor as the fluid quality sensor, it is possible to more accurately determine the progress and quality of the cleaning process. The electric conductivity is close to 0 in normal water, but increases when the cleaning liquid is mixed, and is effective in distinguishing the rinsing process from the cleaning process. The pH value is 6 to 7 for normal tap water, and increases when an alkaline detergent is mixed, and decreases when an acid is mixed. Therefore, it is effective for determining the type of detergent that has been added. Therefore, by using these sensors together as a fluid quality sensor, it is possible to accurately determine the cleaning process and its quality.

  The invention according to claim 3 is the fluid work monitoring apparatus according to claim 1, wherein the work process using the fluid includes a sterilization process, and the work process using the fluid according to the invention according to claim 4 2. The fluid work monitoring apparatus according to claim 1, wherein the fluid work monitoring apparatus is a process in which a cleaning process and a sterilization process are combined. Preferably, by providing an electrical conductivity sensor and a pH sensor as the fluid quality sensor, it is possible to more accurately determine the progress and quality of the sterilization process. The electric conductivity is close to 0 in normal water, but increases when a sterilizing solution is mixed therein, which is effective in distinguishing between the rinsing process and the sterilizing process. The pH value is 6 to 7 for normal tap water, and increases when an alkaline detergent is mixed, and decreases when an acid is mixed. Therefore, it is effective in determining the type of detergent or sterilizing solution introduced. . Therefore, by using these sensors together as a fluid quality sensor, it is possible to accurately determine whether the sterilization process is being performed and whether it is good or bad.

  The invention according to claim 5 is the fluid work monitoring device according to any one of claims 1 to 4, wherein the sensor is at least one of a temperature sensor, an electrical conductivity sensor, and a pH sensor. Therefore, an optimal configuration can be selected according to the type of process, installation environment, and the like. As described above, when more accurate determination is required, a temperature sensor and at least one fluid quality sensor (electrical conductivity sensor or pH sensor) can be provided, and the temperature sensor, electrical conductivity sensor, pH sensor Three types can be provided.

  According to a sixth aspect of the present invention, the fluid work monitoring apparatus further includes display means and input means. The display means displays a process currently being performed (in the case of a milking machine cleaning operation, acid cleaning, alkali cleaning, rinsing) and a determination of whether the operation is good or bad. Even if the order of the processes and the reference values are different, it is possible to select from a plurality of programs by setting from the input means or to rewrite the reference values stored in the recording means, Even when the control program of the external device is updated, it can be easily handled.

  The fluid work monitoring according to any one of claims 1 to 6, wherein the recording means accumulates and records the results of the quality judgment by the work process quality judgment means. Device. By recording the pass / fail judgment, it is possible to prevent the occurrence of defective products and to easily identify the cause of the occurrence of an abnormal situation. When the electrical conductivity data or the like is recorded in the record, it is possible to obtain a more accurate record by correcting these with reference to the measured liquid temperature.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram of an installation method in the case of installing a monitoring device (fluid operation monitoring device) 1 for use in a washing and sterilization process for milking equipment as an example of a fluid operation monitoring device according to the present invention.

Therefore, these devices will not be affected and will not be affected, and there is no need to set communication interfaces or rewrite programs. Can be easily set separately and independently.

  FIG. 2 is a block diagram showing an example of the control circuit. The apparatus of the present embodiment is a milking machine cleaning / sterilization process monitoring apparatus, and can monitor a plurality of cleaning processes and sterilization processes according to an operator's setting. Two types of fluid quality sensors are provided: an electrical conductivity sensor and a pH sensor. In the control box 100, the microcomputer 101 is connected to a temperature sensor 107, an electrical conductivity sensor 108, and a pH sensor 109 via A / D conversion circuits 104 to 106. The temperature sensor 107 is installed in a pipe through which the cleaning liquid / sterilizing liquid circulates, measures and stores the liquid temperature during cleaning or sterilization, and transmits the analog temperature to the A / D conversion circuit 104. The electrical conductivity sensor 108 and the pH sensor 109 measure and store changes in electrical conductivity, pH, and the like in the pipe during cleaning or sterilization, respectively, and transmit them to the A / D conversion circuits 105 and 106 as analog data. The A / D conversion circuits 104 to 106 convert these data into digital data.

  The control circuit 100 also includes a recording unit 102, a start / stop switch 113 as an input unit, a cleaning / sterilization process setting unit 114, a display device 110 and a communication device 111 as output units, and a 5V built-in power source 112. Yes. The display unit is a liquid crystal display device or the like installed on the front surface of the apparatus, and displays the result of determination of each cleaning or sterilization process and the quality of the cleaning / sterilization result. The communication device 111 can output the determined order of steps and stored data of pass / fail judgment to a personal computer or the like equipped with a wireless function by wireless communication means or the like.

  The microcomputer 101 repeats the signals of the A / D conversion circuits 104 to 106 as a logical block by executing the program, and compares it with the reference value read from the recording means 102 to determine the fluid quality. The elapsed time after the condition is established is integrated by the constitution determining means 101a and an internal timer, and compared with the reference value read from the recording means 102, and the progress of the process is received from the control unit of the automatic cleaning device, etc. The cleaning and sterilization process unique judgment means 101b, which is a process type judgment means independently determined by stand alone, and the cleaning and sterilization process pass / fail judgment means 101c, which is a work process quality judgment means for judging the quality result of the cleaning and sterilization process. have. The recording unit 102 is a non-volatile memory, and stores a pass / fail determination and process determination program, a determination process order, a determination reference value table, a current process, past determination data, and the like. The cleaning process may vary depending on the target to be cleaned (milking machine / bulk cooler), the type of milking machine control device, and the automatic cleaning device. It can be selected and set. The setting contents are recorded in the recording means 102, and each procedure is called to the microcomputer 101 in accordance therewith.

  FIG. 3 is an example of a cleaning / sterilization process pass / fail judgment reference value table stored in the recording means 102. The liquid temperature corresponding to the first rinsing process, the alkali cleaning process, the second rinsing process, the acid rinsing process, and the sterilizing process, Reference values for electrical conductivity, pH, and duration are stored. For example, when the liquid temperature of 35 to 50 ° C., the electrical conductivity of 0 to 2 mS / cm, and the pH of 6 to 7 are continued for 60 seconds in the first rinsing step, it indicates that the rinsing step is judged as good. In the case of this example, the reference value of this table also serves as a reference value for process progress judgment. For example, when a liquid temperature of 35 to 50 ° C., an electric conductivity of 0 to 2 mS / cm, and a pH of 6 to 7 are detected, It is determined that the first rinsing process or the second rinsing process is being executed. Whether it corresponds to the first or second rinsing is determined with reference to the processes up to now. Depending on the washing procedure, it is not always necessary to consider all measured values of the liquid temperature, electrical conductivity, and pH value in the determination of the process. Rinse or sterilization process when the liquid temperature is 35 ° C to 50 ° C, when the temperature is 60 ° C or higher It can also be determined as a cleaning step.

  Next, a specific determination procedure for cleaning / sterilization monitoring will be described with reference to the flowcharts of FIGS. In this embodiment, whether each process set in the recording unit 121 is good or bad is determined. If all the processes are good, the overall determination is good, and the display device displays good cleaning. If there is a defective process, all the defective processes are displayed on the display device. For example, in order to monitor the cleaning / sterilization process according to the table of FIG. 3, first, after the start of monitoring, it is determined as the “first rinsing process” based on all or any combination of liquid temperature, electrical conductivity, and pH value. After the quality determination of the “first rinsing step”, the “alkaline cleaning step” is determined based on all or any combination of the liquid temperature, electrical conductivity, and pH value. After the pass / fail judgment of the “alkaline cleaning process”, the “second rinse process” is determined based on all or any combination of the liquid temperature, electrical conductivity, and pH value. After the quality determination of the “second rinsing step”, the “acid rinsing step” is determined based on all or any combination of the liquid temperature, electrical conductivity, and pH value. Then, after the quality determination of the “acid rinsing process” and the comprehensive determination of all the cleaning processes, the “sterilization process” is determined based on all or any combination of the liquid temperature, electrical conductivity, and pH value.

  The determination procedure in each step will be described in detail. First, the cleaning / sterilization monitoring procedure is started by pressing the start / stop switch 114 (S101), and the measurement of temperature, electrical conductivity, and pH is started by each sensor (S102). . Next, the current process stored in the recording means 102 is checked (S103), and if all the cleaning / sterilization processes are completed, the quality of each process is checked (S104). If all the processes are good, the display device displays that all the process results are good (S106). When there is a defective process, the defective process and the defect content are displayed on the display device (S105).

  When the entire cleaning / sterilization process is not completed, the timer count is started or reset (S107). Then, the determination reference value of the process to be determined next is read from the storage unit, and it is checked whether the measured values of temperature, electrical conductivity, and pH satisfy the determination standard at regular intervals (S108). If the temperature / electrical conductivity / pH measurement value criteria are not satisfied, it is checked whether the value of the timer 124 exceeds a predetermined specified time (S109), and the check of S108 is repeated until it exceeds. If the specified time is exceeded, the process is unknown. When the measurement value criteria for temperature, electrical conductivity, and pH are satisfied in S108, the fact is recorded in the recording means 102, and the cleaning or sterilization process name is displayed on the display device (S110). Also, when the specified time has elapsed in S109, the fact that the determination is impossible is recorded in the recording means 102 and then displayed on the display device.

  Next, the quality of the cleaning / sterilization process that is considered to be in progress is determined. In this embodiment, even if the process cannot be determined, it is determined that the next process is being performed. First, the timer is reset and measurement of the working time is started (S111). Then, the measured values of liquid temperature, electrical conductivity, and pH are integrated at regular intervals (S112). Then, the time from the start of the operation is compared with the time reference value obtained by reading the cleaning / sterilization process time from the recording means 102 (S113), and if it is less than the reference value, S112 is repeated. If the measured value is higher than the reference value, the measured value of the liquid temperature, electrical conductivity, and pH recorded in the memory is read, and this is the product of the reference value of each measured value read from the reference value table and the reference value of the cleaning / sterilization process time. The comparison is made (S114), and the determination result is recorded in the recording unit and displayed on the display device (S115). When the pass / fail determination is completed, the integrated values of temperature, electrical conductivity, and pH and the timer for the cleaning process time are reset (S116), and the next cleaning or sterilization process is determined according to the procedure set in the recording unit. In addition, said apparatus structure and algorithm are examples, and are not restricted to this.

  As described above, in the present embodiment, by using the fluid work monitoring device for monitoring the cleaning and sterilization process of the milking equipment, it is possible to suitably prevent harmful effects such as the growth of bacteria inside the milking equipment due to the poor cleaning and sterilization process. Can do.

  In this case, since the monitoring of the cleaning and sterilization process is independently performed without depending on information from an external device that performs cleaning such as the automatic cleaning device 300 or the automatic detergent supply device 302, the automatic cleaning device 300 is used. It is possible to make a reliable determination even when there is an abnormality such as in the automatic detergent supply apparatus 302 or when the cleaning tank 200 is damaged and the detergent leaks out.

  Moreover, although the said embodiment has shown the example which supplied the washing | cleaning sterilization process monitoring apparatus used for the washing | cleaning sterilization process of milking equipment to the washing tank 200 as a fluid operation | work monitoring apparatus which concerns on this invention, a washing | cleaning / sterilization process setting means By changing the output value of the sensor and the setting of the elapsed time by 114, it can be used as it is for other parts of the milking device such as a bulk cooler or completely different equipment such as a bottling line, etc. It is possible to respond flexibly.

  Moreover, although the said embodiment has shown the example of the washing | cleaning sterilization process monitoring apparatus used for the washing | cleaning sterilization process of milking equipment as a fluid work monitoring apparatus which concerns on this invention, it is not limited only to it, detergent and In addition to the bactericidal agent, it can also be used for monitoring processes in which other fluids such as a surface treatment liquid or a coating liquid are used.
