DETAILED DESCRIPTION OF EMBODIMENTS
[0024] Reference is now made to FIG. 1, which illustrates a teat dip application system 10 installed on teats of a dairy animal in a milking parlor 11, and particularly to FIGS. 2A, 2B and 3A, which illustrate a non-limiting construction of the teat dip application system 10.
[0025] Teat dip application system 10 includes a teat cup 12 for receiving therein a teat 13 (FIG. 1). Teat cup 12 has an opening 15 (FIG. 2A) for inserting therein the teat 13. One or more teat dip inlet ports 14 are provided on teat cup 12. In the illustrated embodiment, there are three teat dip inlet ports 14, spaced equally apart (120), but the invention is not limited to this number of ports and the ports do not have to be equally spaced apart. As seen in the enlarged portion of FIG. 1, the teat dip inlet ports 14 may be connected to fluid lines 16, connected to a source of teat dip solution for cleaning and or sanitizing the teats.
[0026] As seen in FIG. 3A, each teat dip inlet port 14 may terminate in an internal nozzle 18 for spraying the teat dip on the teat. The nozzle 18 may be selected for a particular spray pattern, spray velocity, spray fluid flow rate, etc.
[0027] Teat cup 12 further includes one or more inflatable teat holders/scrubbers 20. In the illustrated embodiment, there is one teat holder/scrubber 20, but the invention can have more than one. Teat holder/scrubber 20 may be constructed of an inflatable bladder, made of an elastomeric material, such as natural rubber, synthetic rubber or other suitable materials. One or more inflation ports 22 are in fluid communication with teat holder/scrubber 20 and via fluid lines 23 (FIG. 1) with a fluid source (not shown), such as but not limited to, air, water, teat dip, saline solution, and the like, for inflating teat holder/scrubber 20. The teat holder/scrubber 20 may be deflated by releasing the pressure of the inflation fluid and draining the inflation fluid. A vacuum source (not shown) may be used to expedite the deflation.
[0028] As seen in FIG. 3A, the inner surface of the teat holders/scrubber 20 may have different textures, such as but not limited to, a multi-pointed texture 24, a multi-ribbed texture 26, or a multi-waved texture 28. The different textures provide different holding strengths (the textures have different levels of coefficients of friction) on the teat and different cleansing and scrubbing patterns. The teat cup 12 may include teat holders/scrubbers 20 with all the same texture, or a combination of teat holders/scrubbers 20 with different textures.
[0029] Teat cup 12 may include a lower portion 32 which may have a robotic arm interface member 34 (FIGS. 2A and 3A) for attaching to a robotic arm 36 (FIG. 1). Teat cup 12 may include a drain port 38 (FIGS. 2A and 3A) on lower portion 32. As seen in FIG. 1, robotic arm 36 may be provided with a drainage system 42 for collecting the used teat dip.
[0030] FIG. 3B illustrates another version, in which the teat holders/scrubber 20 is overlaid (covered) with a covering 30, such as but not limited to, cloth, smooth or roughened, membrane and the like. The covering 30 may be useful for sensitive teats or other applications. The covering 30 remains on the teat holders/scrubber 20 both before and after inflation, as seen in the left side illustrations in FIG. 3B.
[0031] Reference is now made to FIGS. 4A, 4B and 4C and FIGS. 5A, 5B and 5C. which illustrate a method of using the teat dip application system 10, in accordance with a non-limiting embodiment of the present invention.
[0032] In FIGS. 4A and 5A, teat cup 12 has been fitted on teat 13. In FIGS. 4B and 5B, teat dip 40 is introduced via teat dip inlet ports 14 and applied onto teat 13. In FIGS. 4C and 5C, teat holders/scrubbers 20 are inflated against teat 13. The teat cup 12 may now be moved down (or up and down) over teat 13 to gently rub the teat dip over teat 13 to thoroughly cleanse teat 13.
[0033] It is noted in FIG. 4C, that separate teat holders/scrubbers 20 may be provided that extend between adjacent teat dip inlet ports 14. Alternatively, one teat holders/scrubber 20 may include discrete inflatable portions that extend between adjacent teat dip inlet ports 14. As another alternative, one teat holders/scrubber 20 may be placed completely below teat dip inlet ports 14 and completely cover the full circumference of the teat.
