The outlet of the release valve 83 is connected to one end of the return tube 93, and the other end of the return tube 93 is stored in the cleaning liquid reservoir through the other tube insertion hole 81 r provided in the lid portion 81 of the cleaning liquid storage tank 12. Insert into tank 12. The drain valve 84 is connected to the middle of the liquid distribution tube 92 located on the upstream side of the release valve 83. On the other hand, one end of a power supply line (electric cable) 82 is connected to the output port of the power supply unit 85d. The power supply line 82 is also connected to all stalls Hp... The vicinity of the cleaning device Ms... Is routed and the other end of the power supply line 82 is connected to the final stage teat cleaning device Ms.

  Next, the nipple cleaning apparatus Ms side will be described. Two connection lines to the brush motor 37 and two connection lines of the operation switch 49 are connected to the inner connection terminal of the connector 38 provided in the cleaning unit U1. The connection line of the operation switch 49 passes through the lower surface of the casing 36 and reaches the inside of the casing 36. And the connector 38 is connected to the 1st connector 65 distribute | arranged to one end surface part in the main body unit Um (upper casing part 61u) via the connection cable 95 (FIG. 8), and the inner side connection terminal of the 1st connector 65 Is directly connected to the second connector 67 disposed on the other end surface portion of the main unit Um (upper casing portion 61u) via a relay line. In addition, the drain port 39 formed integrally with the casing 36 of the cleaning unit U1 is connected to the waste tube connection port 64 of the main unit Um via the waste tube 28. Further, as shown in FIG. 7, the cleaning liquid tubes 27a and 27b are inserted into the waste liquid tube 28, and the outlet ends serving as one ends are connected to the connection ports 35a and 35b provided inside the brush cup section 2 in the cleaning unit U1. Connect to each. On the other hand, the inflow ends, which are the other ends of the respective cleaning liquid tubes 27a and 27b, reach the inside of the lower casing portion 61d through the waste liquid tube connection port 64 of the main unit Um and are connected to the lower end ports of the joint pipes 69a and 69b, respectively. . Thereby, the main unit Um and the cleaning unit U1 are connected by the connection line Us having the waste liquid tube 28 including the cleaning liquid tubes 27a and 27b and the connection cable 95. In this manner, if the cleaning liquid tubes 27a and 27b are inserted into the waste liquid tube 28, even if there are a plurality of cleaning liquid tubes 27a and 27b, the apparent appearance of the single waste liquid tube 28 is sufficient. There is an advantage that appearance can be improved by avoiding complexity.

  On the other hand, in the main body unit Um, two connection lines of the intake fan 17 and a total of four connection lines of the electromagnetic valves 23 a and 23 b are connected to the inner connection terminal of the second connector 67. The upper end of one joint pipe 69a is connected to the outlet 23ao of the electromagnetic valve 23a via a liquid distribution tube, and the inlet 23ai of the electromagnetic valve 23a is connected to a three-way joint 97 (see FIG. 2) Connect to the first connection end. Furthermore, the upper end port of the other joint pipe 69b is connected to the outlet 23bo of the electromagnetic valve 23b via a liquid distribution tube, and the inlet 23bi of the electromagnetic valve 23b is connected to the third side of the three-way joint 97 via the liquid distribution tube. Connect to the two connection ends. The third connection end of the three-way joint 97 is connected to the inner end port of the cleaning liquid tube connection port 66 through the liquid distribution tube. If a Y-shaped tube is used as the liquid distribution tube, the three-way joint 97 is not necessary. In addition, one end of a drainage tube 96 is connected to the drainage part 24, and the other end of the drainage tube 96 faces the drainage channel 202. On the other hand, the second connector 67 disposed on the main unit Um is connected to the control unit Uc via the connection cable 98.

  And control unit Uc ... in each nipple washing | cleaning apparatus Ms ... is each connected to the middle of the power supply line 82 in the shared system part Mc via power supply taking-in line (electric cable) 82s .... In this case, each power supply line 82s... And the power supply line 82 can be connected via a distributor or the like. Thereby, the power supply part 16 which can supply direct-current power with respect to each teat washing apparatus Ms ... from the shared system part Mc is comprised. Further, the outer end ports of the cleaning liquid tube connection ports 66 in the main unit Um are connected to the middle of the cleaning liquid supply line 13 in the shared system section Mc via cleaning liquid intake lines (liquid distribution tubes) 13s. In this case, each of the cleaning liquid intake lines 13s and the cleaning liquid supply line 13 can be connected via a three-way joint or the like. Thus, the cleaning liquid supply unit 14 is configured to circulate the cleaning liquid L accommodated in the cleaning liquid storage tank 12 by the liquid feed pump 11 to the cleaning liquid supply line 13 and return it to the cleaning liquid storage tank 12. The cleaning liquid L can be supplied to Ms.

  As is clear from such a configuration, the function of the shared system unit Mc is excluded from each teat washing apparatus Ms. That is, the functions of the power supply unit 16 and the cleaning liquid supply unit 14 are indispensable functions (components) for each nipple cleaning device Ms... Since each of the nipple cleaning apparatuses Ms... Is provided with the unit 16 and the cleaning liquid supply unit 14, the functions of the power supply unit 16 and the cleaning liquid supply unit 14 in the shared system unit Mc are removed.

  Next, the usage method and operation | movement of the nipple washing | cleaning system 1 which concern on this embodiment are demonstrated based on FIGS. 9-11, referring FIGS.

  When the nipple cleaning system 1 is used, a predetermined amount of the cleaning liquid L is stored in the cleaning liquid storage tank 12, and the main control panel Uo is turned on. As a result, DC power is output to the power supply line 82 and supplied to each power supply line 82s. Further, the cleaning liquid L circulates in the cleaning liquid supply line 13, and the cleaning liquid L is supplied to each of the cleaning liquid intake lines 13s.

  Then, when performing the cleaning operation (wiping operation), the operator holds the cleaning unit U1 by hand, and inserts the nipple Cm of the cow C into the insertion opening 2i of the brush cup portion 2, as shown in FIG. Since the second cleaning brush portion 3b in the cleaning unit U1 is biased upward by the springs 38 ..., when the nipple Cm is not inserted, it is at the highest position shown in FIG. 8, but the nipple Cm is inserted. Then, as shown in FIG.

  On the other hand, the cleaning includes preliminary cleaning and main cleaning. FIG. 9 shows a timing chart of a sequence control pattern used when performing preliminary cleaning and main cleaning. First, pre-cleaning is performed. The preliminary cleaning is performed for the purpose of facilitating removal of dirt in the main cleaning by wetting each teat Cm... With the cleaning liquid L before the main cleaning.

  First, the operator pushes the operation switch 49 while holding the cleaning unit U1 by hand to turn it on. In this case, the liquid feed pump 11, the electromagnetic valves 23a and 23b, the brush motor 37, and the intake fan 17 are turned on in response to the operation switch 49 being turned on. When the liquid feed pump 11 and the electromagnetic valves 23a and 23b are turned on, the cleaning liquid L is supplied to the upper injection unit 5a and the lower injection unit 5b via the two cleaning liquid supply systems 15a and 15b, that is, the cleaning liquid tubes 27a and 27b, respectively. The Then, as shown in FIG. 10, the cleaning liquid L is injected above the cleaning member 22 from the upper injection holes 33 a... And is injected below the cleaning member 22 from the lower injection holes 33 b. Further, power is supplied to the brush motor 37 via the control unit Uc, the connection cable 98, and the connection cable 95, and the brush motor 37 repeats forward rotation and reverse rotation alternately (in the direction of arrow Fpn in FIG. 10). In FIG. 9, Ts indicates the normal rotation (or reverse rotation) time, and Ti indicates a slight stop time of the brush motor 37 between the normal rotation and the reverse rotation. The forward / reverse times can be set to about 0.4 to 0.8 [seconds]. By the rotation of the brush motor 37, the first cleaning brush portion 3a, the second cleaning brush portion 3b, and the cleaning member 22 rotate together, and preliminary cleaning of the teat Cm is performed. Further, since the inside of the waste liquid storage unit 25 and the waste liquid tube 28 is sucked by the intake fan 17 being turned on, the used cleaning liquid L inside the brush cup unit 2, that is, the waste liquid Lr, passes through the waste liquid tube 28. It is collected and temporarily stored in the waste liquid storage unit 25 in the unit Um. At this time, since the inside of the waste liquid storage unit 25 is sucked, the liquid discharge unit 24 is closed by the check valve 24v.

  Then, the operator releases (OFF) pressing of the operation switch 49 at an appropriate time. In FIG. 9, Ta indicates the ON time of the operation switch 49. The preliminary cleaning is intended to wet the nipple Cm with the cleaning liquid L, and therefore, a short time of about several seconds is sufficient as the time Ta. For the time Ta, the maximum time Tam is set, and when this maximum time Tam is exceeded, a control pattern in the main cleaning described later is obtained. When the operation switch 49 is turned off, the liquid feed pump 11, the electromagnetic valves 23a and 23b, and the brush motor 37 are turned off. However, even if the operation switch 49 is turned off, the intake fan 17 is turned off after a time Tb, for example, about several seconds. Thereby, since the intake air inside the waste liquid storage unit 25 is released, the check valve 24v of the drainage unit 24 is opened, and the waste liquid L in the waste liquid storage unit 25 passes through the drainage unit 24 and the drainage tube 96. And drained into the drainage channel 202. In this way, if the waste liquid collecting means 18 is provided with the waste liquid storage section 25 that is connected to the waste liquid tube 28, becomes negative pressure by the intake fan 17, and has the drainage section 24 that discharges the collected waste liquid Lr to the outside. There is an advantage that the waste liquid Lr can be reliably recovered and then reliably disposed at a predetermined disposal place. Thus, the preliminary cleaning of one nipple Cm is completed. The same preliminary cleaning is sequentially performed on the other three teats Cm.

  When the preliminary cleaning is completed, the main cleaning is then performed. Although the basic operation in the main cleaning is the same as that in the preliminary cleaning, the operator can arbitrarily change the time for pressing the operation switch 49 (ON time) in consideration of the degree of contamination of the teat Cm. First, the nipple Cm is inserted into the cleaning unit U1. Then, the operation switch 49 is pressed to turn it ON. When the operation switch 49 is turned on, the liquid feed pump 11, the electromagnetic valves 23a and 23b, the brush motor 37, and the intake fan 17 are turned on. Accordingly, as in the case of the preliminary cleaning, the cleaning liquid L is supplied to the upper injection unit 5a and the lower injection unit 5b via the cleaning liquid tubes 27a and 27b. Then, as shown in FIG. 10, the cleaning liquid L is injected above the cleaning member 22 from the upper injection holes 33 u... And is injected below the cleaning member 22 from the lower injection holes 33 d. Further, the brush motor 37 alternately repeats forward rotation and reverse rotation (in the direction of arrow Fpn in FIG. 10). By the rotation of the brush motor 37, the first cleaning brush portion 3a, the second cleaning brush portion 3b, and the cleaning member 22 are integrally rotated, and main cleaning is performed on the teat Cm.

  In this case, the first cleaning brush portion 3a cleans the peripheral surface portion Cmf of the nipple Cm with the brush-like cleaning brush 3ax. Further, the second cleaning brush portion 3b cleans the boundary surface portion at the tip portion Cms of the nipple Cm with the boundary surface cleaning brush 3bx... And the tip surface portion portion at the tip portion Cms of the nipple Cm with the tip surface cleaning brush 3bc. Wash. At this time, the boundary curved surface cleaning brushes 3bx... Are sheet-like and have an advantage that dust does not easily adhere to them, and the tip surface cleaning brush 3bc uses cylindrical protrusions 43. In particular, there is an advantage that various shapes including a recess at the tip Cms of the nipple Cm can be cleaned. Further, by the rotation of the cleaning member 22, the root portion Cmb in the teat Cm is cleaned by the cleaning unit 22 w (fin-shaped portion 22 wf...), And this cleaning is performed by injection from the upper injection unit 5 a disposed above the cleaning member 22. The cleaning liquid L to be used is used. At this time, since the disc-shaped cleaning member 22 is used, the dust is removed by the cleaning member 22 before being scraped off by the brush of the brush mechanism unit 3 and is quickly flushed by the cleaning liquid L. . That is, the cleaning liquid L used for cleaning the root portion Cmb enters the inside through the gap between the insertion hole 22i of the cleaning member 22 and the nipple Cm by the cleaning water pressure and the suction pressure, and travels through the peripheral surface portion Cmf of the nipple Cm to the tip Cms. Flushed to the side. Further, since the inside of the waste liquid tube 28 is sucked by the intake fan 17, the waste liquid Lr inside the brush cup portion 2 is collected and temporarily stored in the waste liquid storage portion 25 of the main unit Um via the waste liquid tube 28. The

  Then, the operator releases (OFF) pressing of the operation switch 49 at an appropriate time. In FIG. 9, Td indicates the ON time of the operation switch 48. Since the main cleaning is regular cleaning, the time Td is set longer than the time Ta during the preliminary cleaning. In the example, the time Td is about twice the time Ta. Since the time Td exceeds the maximum time Tam, when the maximum time Tam elapses, one electromagnetic valve 23a is automatically turned OFF, and the injection of the cleaning liquid L from the upper injection unit 5a is stopped. Therefore, after the maximum time Tam has elapsed, the substantial cleaning of the root portion Cmb of the nipple Cm is completed, and the cleaning member 22 starts draining and drying by the rotating fin-like portions 22wf.

  When the operation switch 49 is turned OFF, the rotation of the brush motor 37 rotates only in the forward rotation direction (in the direction of arrow Fp in FIG. 10) as shown in FIG. Thereafter, after a preset Te time (for example, about several seconds), the other electromagnetic valve 23b and the brush motor 37 are turned off. Therefore, after the operation switch 49 is turned OFF, the cleaning unit U1 is detached from the teat Cm within this Te time. In this case, since the cleaning member 22 functions as a blower fan by the rotating fin-like portions 22wf ... within the Te time, the cleaning unit U1 is quickly removed from the teat Cm within the Te time. Smooth draining and drying. In particular, in addition to such a fan function, even when the cleaning liquid L is continuously sprayed from the lower spraying portion 5b during the separation, the portion of the peripheral surface portion Cmf of the nipple Cm is larger than the insertion hole 22i of the cleaning member 22 In addition, liquid drainage is performed by the insertion hole 22i, and a portion where the diameter of the peripheral surface portion Cmf of the nipple Cm is smaller than the insertion hole 22i of the cleaning member 22 is a high-speed approach of air from the gap between the insertion hole 22i and the peripheral surface portion Cmf. Rapid liquid draining and drying can be performed by rotating the brush mechanism unit 3 only in the forward rotation direction. FIG. 11 shows a state at the time of separation. When the Tf time (for example, about several seconds) elapses after the Te time has elapsed, the intake fan 17 is automatically turned off. Thus, the main cleaning of one nipple Cm is completed. The same main cleaning is sequentially performed on the other three teats Cm. Thereby, a series of cleaning operations are completed.

  Therefore, according to the teat cleaning system 1 according to this embodiment, the cleaning liquid supply that circulates the cleaning liquid L stored in the cleaning liquid storage tank 12 by the liquid feed pump 11 to the cleaning liquid supply line 13 and returns the cleaning liquid L to the cleaning liquid storage tank 12. A shared system section Mc having at least a section 14 is installed in the barn H, and at least one nipple cleaning device Ms ... excluding the function of the shared system unit Mc is associated with each stall Hp ... in the barn H Since each nipple cleaning device Ms... Is connected to the shared system unit Mc, even when a small nipple cleaning device Ms having portability is installed in a stall Hp. It is possible to improve work efficiency by reducing unnecessary man-hours such as frequent additional work of the cleaning liquid L. Further, at least the liquid feeding pump 11 and the cleaning liquid storage tank 12 are shared by the teat cleaning apparatuses Ms... By the sharing system unit Mc. Therefore, when installing a plurality of teat cleaning devices Ms... For the stall Hp... In the barn H, the cost of the entire system 1 can be reduced by reducing the number of parts, and the installation area can be saved by making the device Ms small and compact. Space can be improved.

  In addition, the nipple cleaning device Ms has cleaning liquid supply means having at least two cleaning liquid supply systems 15a and 15b capable of supplying the cleaning liquid L supplied from the cleaning liquid supply unit 14 to at least two injection units 5a and 5b in the cleaning unit U1. 6, a waste liquid collecting means 18 that can suck and collect the waste liquid Lr discharged from the cleaning unit U <b> 1 by the intake fan 17, and an operation control means 19 that controls the operations of the cleaning liquid supply means 6 and the waste liquid collecting means 18. Therefore, effective and sufficient cleaning (wiping) for the nipple Cm can be performed. Therefore, adhesion of dirt to the teat cup liner is avoided, which can contribute to ensuring hygienic production of milk, preventing milk quality deterioration and mastitis, and eliminating residual dirt. Additional cleaning by work can be made unnecessary or reduced.

  By the way, the illustrated nipple cleaning apparatus Ms includes a main body unit Um, a control unit Uc, and a cleaning unit U1, and is attachable to and detachable from the support frame 51. Therefore, the main body unit Um and the cleaning unit U1 can be removed from the support frame 51, and as shown in FIG. 12, it can be easily changed to a mobile (portable) teat cleaning device Me used alone in a tethered barn. . Although this change is a change in an actual use stage, it means that the teat washing apparatus Ms can be used for two types even in the manufacturing stage. The nipple cleaning apparatus Me shown in FIG. 12 includes a carriage unit 101 that is mounted with a cleaning unit U1 and a main body unit U2 and is movable. The main body U2 includes a cleaning liquid reservoir 102 that stores the cleaning liquid L, and a control unit Uc to which the liquid feed pump 103 is attached. In this case, the cleaning liquid storage unit 102 corresponds to the above-described cleaning liquid tank unit 12, and the liquid feeding pump 103 corresponds to the above-described liquid feeding pump 11. In addition, 105 is a cart body, 106... Is a wheel unit, 107 is a handle unit, and 108 is a support unit that supports the body unit Um and the cleaning unit U1, and is rotatably provided on the upper surface of the cart body 105. .

  Therefore, when using the nipple cleaning device Me, the operator pushes the nipple cleaning device Me by hand, and as shown in FIG. 13, in the cowshed, particularly in the tethered cowshed suitable using the nipple cleaning device Me. Move to any place of use. The operator can hold the cleaning unit U1 by hand and insert the teat Cm of the cow C into the insertion opening 2i of the brush cup unit 2, and can use the same as the teat cleaning device Ms described above. Thus, since the nipple washing | cleaning apparatus Ms in this embodiment comprises a part or all which comprises the said nipple washing | cleaning apparatus Ms so that attachment or detachment is possible with respect to an installation site | part (stall Hp), it is arbitrary in a tethered cowshed etc. It can be easily changed to a teat cleaning device Me that moves and is used alone, and the teat cleaning device Ms can be used as both a barn H and a tethered barn. Such a nipple cleaning device Me can be easily handled even when used for a large number of cows C ... like a tethered cowshed, and is easy to use, more convenient and practical. Can be increased. Moreover, there is an advantage that the work efficiency can be improved by reducing unnecessary man-hours such as frequent addition work of the cleaning liquid L.
