Abstract
Description
- The present invention relates to a filling nozzle for use in filling a liquid of high viscosity, such as curry roux or like food, into containers in a specified amount in each container.
- Such filling nozzles are already known which comprise a tubular nozzle body having an inlet at an intermediate portion of the height of its peripheral wall for receiving a liquid forced thereinto in a specified amount at a time and a discharge outlet provided by a lower-end opening of the peripheral wall, and a liquid pushing-out rod slidably fitted in the nozzle body so as to open and close the inlet.
- When the nozzle is used for a liquid filling operation, the liquid in the nozzle body is wholly pushed out by the rod to fill a container with the completion of one cycle of filling operation. However, it is likely that the liquid forced out will partly adhere to the rod and remain thereon.
- No problem will arise if the liquid portion remains adhering to the rod until the subsequent filling cycle is started, but the liquid is likely to fall off. When the falling liquid adheres to the surface of the container to be sealed, the container will not be sealed properly. Adhesion of the liquid to the container transport holder or the like is objectionable from the viewpoint of sanitation.
- The main object of the present invention is to provide a nozzle for filling a liquid in specified amounts which comprises a tubular nozzle body having an inlet at an intermediate portion of the height of its peripheral wall for receiving the liquid forced thereinto in the specified amount at a time and a discharge outlet provided by a lower-end opening of the peripheral wall, and a liquid pushing-out rod slidably fitted in the nozzle body so as to open and close the inlet, the nozzle being characterized in that at least a lower end surface included in the entire outer surface of the rod is rendered hydrophobic.
- With the liquid filling nozzle of the present invention, at least the lower end surface of the rod is so treated as to be hydrophobic and therefore will not permit the adhesion of the liquid thereto. If the liquid adheres to the rod and falls off inadvertently, the liquid is likely to adhere to the surface of the container to be sealed to result in imperfect sealing, or is likely to adhere to the container transport holder or the like to entail the problem of impaired sanitation, whereas the present invention has obviated such problems.
-
- FIG. 1 is a view in vertical section of a filling apparatus including a filling nozzle embodying the invention; and
- FIG. 2 is a sectional view showing the lower end portion of the nozzle on an enlarged scale.
- An embodiment of the invention will be described below with reference to the drawings.
- The illustrated filling apparatus comprises a
tank 12 disposed above acontainer conveyor 11 for containing the liquid to be filled, avertical filling pipe 13 connected at its upper end to the bottom wall of thetank 12, ahorizontal check cylinder 17 intersecting an upper portion of thefilling tube 13 at right angles therewith, housing apiston 15 therein and provided with ajacekt 16 for preventing the liquid from solidifying, thepiston 15 having afluid channel 14 extending therethrough, ahorizontal metering cylinder 19 projecting leftward from the lower portion of thefilling pipe 13 and having a piston 18 therein, amovable filling pipe 22 rockably suspended from the lower end of thefilling pipe 13 and provided with ajacket 21 for preventing the liquid from solidifying, and a fillingnozzle 23 attached to the lower end of thefilling pipe 22. - The
filling pipe 13 is provided at its lower end with a horizontal cylindrical member 24 for suspending thefilling pipe 22. The suspending member 24 has acommunication channel 25 which has one end opened leftward for communication with thefilling pipe 13 and the other end opened downward. Ahorizontal rotary tube 26 is fitted in the suspending member 24 so as to cover the downward opening of thechannel 25. Thefilling pipe 22 has an upper end connected to thetube 26. - The
filling nozzle 23 comprises atubular nozzle body 33, and arod 34 for pushing out the liquid to be filled. Thenozzle body 33 has aninlet 31 formed at an intermediate portion of the height of its peripheral wall and connected to the lower end of thefilling pipe 22, and adischarge outlet 32 provided by a lower-end opening of the peripheral wall. Therod 34 is slidably fitted in thenozzle body 33. - Connected by a
yoke 35 to the upper end of thenozzle body 33 is ahydraulic cylinder 36, which has apiston rod 37 extending downward into theyoke 35. The pushing-outrod 34 has an upper end projecting upward beyond thenozzle body 33 and connected to thepiston rod 37. - As shown in greater detail in FIG. 2, the lower end surface of the pushing-out
rod 34 has a projectingtapered face 41 at an outward portion thereof and a recessedconical face 42 at an inward portion thereof. An annularflat face 43 is formed at the boundary between thetapered face 41 and theconical face 42. Thetapered face 41, theconical face 42 and theflat face 43 are all formed with a Teflonlayer 44. - In the state shown in FIG. 1, the
check piston 15 is in its leftward limit position to hold thecheck cylinder 17 open, the metering piston 18 is in its rightward limit position, and the liquid pushing-outrod 34 is in its lower limit position, holding theinlet 31 and thedischarge outlet 32 closed. When the metering piston 18 is moved leftward in this state, the liquid to be filled flows out of thetank 12 into thefilling pipe 13. Upon the metering piston 18 reaching its leftward limit position, thecheck piston 15 is moved rightward to close thecheck cyinder 17, and the pushing-outrod 34 is raised to open theinlet 31 and theoutlet 32. The metering piston 18 is then moved rightward, whereby the liquid in thefilling pipe 13 is forced through theinlet 31 into thenozzle 23, further discharged from theoutlet 32 and filled into a container C as transported to a position below the outlet. If thenozzle 23 is rocked over a predetermined range when the liquid is delivered from thedischarge outlet 32, the liquid fills the container C to a flat level without forming an upwardly bulging shape inside the container C. Upon the metering piston 18 reaching its rightward limit position, the feed of liquid from thefilling pipe 13 is discontinued, where-upon the pushing-outrod 34 is lowered to force out the liquid from thenozzle 23. One cycle of filling operation is completed when therod 34 reaches its lower limit position. - The Teflon
layer 44 is formed by coating the lower end surface of the pushing-outrod 34. Teflon has a hydrophobic property, therefore repels the liquid even if the liquid tends to adhere to the rod end surface and consequently renders the end surface free from the liquid. - Although an unillustrated chromium plating layer is formed over the side surface of the
rod 34 in the above embodiment, this layer may be replaced by a Teflon layer.
Claims (4)
- A nozzle for filling a liquid in specified amounts comprising:
a tubular nozzle body 33 having an inlet 31 at an intermediate portion of the height of its peripheral wall for receiving the liquid forced thereinto in the specified amount at a time and a discharge outlet 32 provided by a lower-end opening of the peripheral wall, and
a liquid pushing-out rod 34 slidably fitted in the nozzle body 33 so as to open and close the inlet 31,
the filling nozzle being characterized in that at least a lower end surface included in the entire outer surface of the rod 34 is rendered hydrophobic. - A nozzle as defined in claim 1 wherein the lower end surface of the rod 34 has a projecting tapered face 41 at an outward portion thereof and a recessed conical face 42 at an inward portion thereof.
- A nozzle as defined in claim 2 wherein the rod 34 is movable upward and downward to a lower limit position where the upper end of the tapered face 41 is at the same level as the lower end face of the nozzle body 33.
