Description

  The present invention relates to a milk sampling apparatus for sampling milk by a quarter in order to identify a quarter affected by mastitis in a milking machine.

  If a cow is affected by mastitis, the quality of the milk will deteriorate and it will also infect other cows, so it must be detected and treated early. In order to detect mastitis at an early stage, the milk is sampled at an appropriate timing before or during milking, and the color, the number of contained bacteria, the number of somatic cells, etc. are examined. This sampling is preferably performed for each quarter so that the quarter affected by mastitis can be identified. Traditionally, before or during milking, sampling was done by hand squeezing every quarter with the milking equipment removed, but it takes time and is especially troublesome when sampling during milking. Therefore, there is a problem that the sampling work needs to be performed and reattached after completion, which further complicates the work.

  FIG. 3 shows an example of a milking machine that can automatically perform sampling for each quarter. In this milking machine, each of the four teat cups 11 is connected to a dedicated milk tube 12 leading to the milk line M, and each milk tube is provided with a sampling device in which a sampling bottle is connected via an electromagnetic valve for sampling. I was going. The pulsating vacuum pressure is supplied to the teat cup 11 from a pulsator (not shown) and milking is performed, and at the same time, the electromagnetic valve of each sampling unit is opened for a certain period of time to sample the milk every quarter. By collecting the milk from the teat cup directly to the sampling section without collecting it in the milk claw, it is possible to collect milk for each milk separation.

  In the milking machine as shown in FIG. 3, milking and sampling can be performed automatically without removing the milking unit, but in order to provide a dedicated milk tube 12 for each teat cup 11, four milk tubes are routed to the milk line. There was a problem that the operability was bad. Moreover, since the load of the milk tube is applied to each teat, there was a tendency to easily cause a liner slip that causes mastitis. Furthermore, since the automatic detachment device that automatically raises the milk claw and collects the milking unit at the end of milking cannot be used, it is necessary to remove one teat cup at a time, and there is a limit to labor saving.

  Accordingly, an object of the present invention is to provide a milk automatic sampling apparatus with high practicality, which can sample milk for each quarter and can be used in combination with a milk claw or an automatic withdrawal apparatus.

  The invention described in claim 1 of the present application is a milking unit composed of a milk claw and a plurality of teat cups, a milk tube for delivering milk in the milk claw, and a component capable of supplying vacuum pressure to each teat cup individually. A pulsator according to a tuft, a sampling valve having a number equal to or more than that of a teat cup provided with a solenoid valve and a sampling bottle by branching the milk tube, and a control means for controlling the pulsator according to the tuft and the solenoid valve. The vacuum piping type milking machine is characterized in that the means supplies the vacuum pressure to the plurality of teat cups sequentially and opens the corresponding electromagnetic valves in order to individually collect the milk from each milking into a sampling bottle. The above-described problem is solved by a bobbin milk automatic sampling device.

  In other words, a pulsator for each quarter is installed in a general milking unit, and the pulsator for each quarter is individually controlled, and a sampling bottle is attached to the tube from the milking unit via a solenoid valve, By operating the solenoid valve in time with the milk outflow, the milk from each quarter is automatically collected in the sampling bottle.

  Specifically, immediately after the start of milking, only one pulsator is operated and milked for a certain period of time, and sampling is performed by opening the solenoid valve of the corresponding sampling bottle at the timing when the spilled milk flows. Then, when a certain time has elapsed, the pulsator of the next quarter is operated to perform sampling. By performing this operation for all the quarters, it is possible to perform milk sampling for each quarter. When transitioning from one quarter to another, it is preferable to delay the sampling timing so that milk from the previous quarter is still in the milk tube and does not mix. After completion of sampling, it is possible to shift to a normal milking mode and perform milking automatically, or to perform sampling during milking.

The invention according to claim 2 is a milking unit comprising a milk claw and a plurality of teat cups, a milk tube for delivering milk in the milk claw, and a pulsator for each quarter capable of individually supplying a vacuum pressure to each teat cup A milk collecting part in which a branch part is provided in the milk tube and an upper solenoid valve, a milk storage space, a lower solenoid valve, and a milk outlet are provided in order, and the milk bottles are selectively used in a number equal to or more than the number of teat cups. A turntable that can be set under the outlet, and a control means for controlling the pulsator for each of the quarters, each solenoid valve and the turntable, the control means supplies a vacuum pressure to the teat cup by the pulsator for each of the quarters, Rotate the turntable and set the corresponding sampling bottle under the milk outlet, and the milk collection part will follow the following steps:
(1) Open the upper and lower solenoid valves at the same time to discharge the milk in the milk collecting part in reverse flow,
(2) Open the upper solenoid valve, close the lower solenoid valve and store the milk in the milk storage space,
(3) Collecting milk from each divided milk individually in a sampling bottle by closing the upper solenoid valve, opening the lower solenoid valve, and operating the milk stored in the milk storage space as it is discharged from the milk outlet. The above-described problems are solved by the automatic milk sampling apparatus according to quarters.

  That is, by installing a milk collection unit that provides a branch tube to the milk tube and discharging milk, and by selectively setting a sampling bottle at the milk outlet, sampling from a large number of quarters can be performed with only two solenoid valves. Is what you do. Specifically, after the start of milking, the corresponding sampling bottle is set at the milk outlet, only one pulsator of the quarter is operated, milking is performed for a certain period of time, and the milk collecting part is operated at the timing when the spilled milk flows And perform sampling. After the sampling is completed, the next sampling bottle is set at the milk outlet, and the corresponding pulsator is operated to perform sampling sequentially. As in the case of claim 1, it is preferable to delay the sampling timing so that the milk from the previous quarter is not mixed.

  The operation procedure of the milk collecting unit will be described in more detail. First, in order to discharge the milk remaining in the branch pipe, the upper and lower electromagnetic valves are opened and air is introduced from the milk outlet to the milk tube. Reverse the flow and wipe out residual milk. After a predetermined time, the upper electromagnetic valve is opened and the lower electromagnetic valve is closed, and the milk flowing through the milk tube is stored in the milk storage space. Further, after a predetermined time, the upper electromagnetic valve is closed and the lower electromagnetic valve is opened, and the milk is discharged from the milk outlet and collected in a corresponding sampling bottle set below. After completion of sampling, it is possible to shift to a normal milking mode and perform milking automatically, or to perform sampling during milking.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an overall view in the case where the milk sampling apparatus according to the first embodiment of the present invention is applied to a low-line vacuum pipe type milking machine. Milk line M and vacuum line V are part of the milking machine.

  The milking unit 1 includes a milk claw 10 and four teat cups 11 similar to those used in normal milking. A pulsation tube 20 is connected to the connection port on the side surface of each teat cup 11, and is connected to the vacuum line V via an individual pulsator 21 for each quarter. Each pulsator 21 is controlled by the control device 100 and pulsates individually with respect to the pulsation chamber of each teat cup 11 by alternately switching the connection destination of the pulsation tube 20 between the vacuum line V and the atmosphere. Milking can be performed by supplying a vacuum pressure. Moreover, the lower part of each teat cup 11 is connected to the milk claw 10 through a short milk tube, and once squeezed milk is collected into the milk claw. Milk accumulated in the milk claw 10 is conveyed to the milk line M by the milk tube 12. In the middle of the milk tube 12, four sampling units 30 corresponding to each teat cup 11 are provided in series. Each sampling unit 30 includes an electromagnetic valve 31 controlled by the control device 100, an opening 33, and a sampling bottle 32. There is a slight gap between the sampling bottle 32 and the opening 33, and the sampling bottle 32 is sucked by the vacuum pressure in the milk tube 12 to be in close contact therewith. The milk tube 12 is further provided with a milk meter 13 to measure and display the passed milk flow rate and to output it to the control means 100.

  The automatic removal device 24 is a device that is controlled by the control device 100 and automatically recovers the milking unit by pulling up the removal rope bound to the milk claw 10. The control device 100 includes a pulsator control unit 101 for each quarter, an automatic withdrawal control unit 102, a milk amount measurement unit 103, an operation unit 106, a display unit 107, a sampling control unit 108, and a motor control unit 109. In addition, it is a device for controlling the pulsator 21 for each quarter, the automatic detachment device 24 and the sampling unit 30 according to the input from the touch panel.

  The procedure in the case of sampling at the start of milking using the milking machine of a present Example and the effect | action of each part are demonstrated. When an operator attaches the teat cup 21 of the milking unit 1 to each teat in the same manner as in normal milking and instructs the sampling start from the operation unit 106, the individual pulsator control unit 101 of the control device 100 performs the first quartering. The other pulsator 21a is operated to perform milking from the quarter a. Since the other pulsator 21 for each quarter is stopped, only the milk from the quarter a flows into the milk claw 10. When milking is performed for about 20 seconds, the flow of milk reaches the sampling unit 30, so that the sampling control unit 108 opens the electromagnetic valve 31 for about 10 seconds after 20 seconds and collects milk in the sampling bottle 32. When the electromagnetic valve 31 is opened, first, air flows from the gap between the sampling bottle 32 and the opening 33, and the residual milk remaining in the branch pipe is made to flow backward and discharged. When the sampling bottle 32 is sucked upward and comes into close contact with the opening 33, the inflow of air stops, and the milk flows into the sampling bottle 32. Since the waiting time of the sampling unit and the time for opening the electromagnetic valve 31 vary depending on the apparatus and the size of the bottle, etc., they can be appropriately changed by input from the operation unit 106.

  When the collection of milk is completed for the quarter a, the quarter-by-part pulsator control unit 101 stops the quarter-by-part pulsator 21a and activates the next quarter pulsator. Then, after about 20 seconds have passed for the milk remaining in the milk claw 10 and the milk tube 12 remaining in the milk tube 12 to be washed away and replaced by new milk, the next sampling unit 30 Collect milk. The waiting time of 20 seconds can also be changed as appropriate by input from the operation unit. After the sampling for the four quarters is completed in this way, the quarterly pulsator control unit 101 operates the quarterly pulsator 21 for all the quarters to perform a normal operation. When the milk amount measurement unit 103 of the control device determines the end of lactation by input from the milk meter 13, the automatic removal control unit 102 operates the automatic removal device 24 to return the milking unit to the original position and display The end of work is displayed by the unit 107. The operator confirms the completion of the work, removes the four sampling bottles 32, and gives them to a predetermined examination, thereby performing the milk analysis for each quarter and identifying the quarter affected by mastitis. .

  FIG. 2: is a figure which shows the structure of the sampling part 40 at the time of applying the milk sampling apparatus according to Example 2 which concerns on Example 2 of this invention to the vacuum piping type milking machine of a low line, (a) is the sampling part 40. The side view of the whole, (b) is a plan view showing the positional relationship between the turntable and the milk outlet. Since each device other than the sampling unit 40 is the same as that in the first embodiment, the description thereof is omitted.

  The sampling unit 40 of this embodiment is not individually installed for each quarter, but is provided with one device corresponding to all the quarters. The sampling unit 40 includes a milk collecting unit 50 that collects a certain amount of milk from the milk tube 12 and a turntable 60 that distributes the collected milk to a plurality of bottles. The milk collection unit 50 provides a milk storage space 53 in the branch pipe 51 branched from the milk tube 12 via the upper electromagnetic valve 52, and further provides a milk outlet 55 in the lower part of the milk storage space 53 via the lower electromagnetic valve 54. It is a thing. The turntable 60 has a predetermined number of sampling bottles on eight seats provided at intervals of 45 ° around a circular table body 63 coupled to a vertical rotary shaft 62 driven by a piston type rotary actuator 61. 64 so that any sampling bottle 64 can be selectively set under the milk outlet 55. The rotary actuator 61 is controlled by the motor control unit 109 of the control means 100.

  In the separate milk sampling apparatus according to the present embodiment, when the operator attaches the teat cup 21 of the milking unit 1 to each teat and instructs the sampling start from the operation unit 106, the individual pulsator control unit 101 of the control apparatus 100 Operates the first pulsator 21a for each quarter, and performs milking from the quarter a. Since the other pulsator 21 for each quarter is stopped, only the milk from the quarter a flows into the milk claw 10. When milking is performed for about 20 seconds, the milk flow reaches the sampling unit 40, but since the milk collected at the previous sampling may remain in the milk collecting unit 50, the sampling control unit 108 of the control device 100 may First, the upper electromagnetic valve 52 and the lower electromagnetic valve 54 are opened to introduce atmospheric pressure from the milk outlet 55, and the milk in the branch pipe 51 and the milk storage space 53 is caused to flow backward and discharged from the milk tube 12. After about 0.2 seconds, only the lower solenoid valve 54 is closed while the upper solenoid valve 52 is opened, and the milk in the compartment a is stored in the milk storage space 53 from the milk tube 12. After 10 seconds, the upper electromagnetic valve 52 is closed to shut off the milk feeding vacuum pressure in the milk tube 12 and then the lower electromagnetic valve 54 is opened to collect milk in a sampling bottle 64 set below the milk outlet 55. To do. Since the waiting time, the milk discharge time, and the storage time vary depending on the apparatus, the size of the bottle, and the like, the waiting time, the milk discharging time, and the storage time can be appropriately changed by input from the operation unit 106.

  When the collection of milk is completed for the quarter a, the quarter-by-part pulsator control unit 101 stops the quarter-by-part pulsator 21a and activates the next quarter pulsator. Then, after about 20 seconds have passed for the milk remaining in the milk claw 10 and the milk tube 12 remaining in the milk tube 12 to be washed away and replaced by new milk, the next sampling unit 30 Collect milk. The waiting time of 20 seconds can also be changed as appropriate by input from the operation unit. Meanwhile, the motor control unit 109 drives the stepping motor 61 to rotate the turntable 60 by 45 °, and sets the next sampling bottle 64 below the milk outlet 55. After the sampling for four quarters is completed in this way, the quarterly pulsator controller 101 operates the quarterly pulsator 21 for all the quarters to perform normal milking. In the same manner as described above, end processing by the automatic detachment device 24 and end display by the display unit 107 are performed. The worker confirms the completion of the work, removes the four sampling bottles 32 from the turntable main body 64, and performs a predetermined inspection.

  According to the milk sampling apparatus according to the present invention, since the milk sampling and milking work can be automatically performed for each quarter, and the mastitis can be identified, the quality control of the milk and the health management of the cow There is a big effect.
