This invention has for its object a spraying rotor for a dish or industrial glassware washing machine, characterized by the fact that it comprises a main arm pivoted along its transverse symmetry axis, provided with a propulsion nozzle, carrying at each of its ends a rotatable injector and by the fact that the assembly of each injector on the main arm comprises a compensating device of the push so that in working the injector revolves freely.
The attached drawing shows schematically and by way of example one embodiment of the rotor and some variants of it.
FIG. I is a partial cross-section of the rotor.
FIG. 2 is a partial view of it seen from above.
FIG. 3 is a plan view, certain parts being broken away showing the central part of an injector.
FIG. 4 is a cross-section taken along line lV--IV of FIG. 1.
FIG. 5 is a partial cross-section of a variant of the pivoting system of an injector on the main arm.
FIG. 6 is a schematic side view of a washing machine for industrial glassware provided with the rotor as well as with an accessory.
FIG. 7 is a plan view of the machine shown in FIG. 6.
The rotor shown, intended to equip a washing machine for industrial glassware comprises a main arm 1 pivoted in a known way on the end of a duct 2 feeding water into the tank of the washing machine. Generally the duct 2 merges into the tank of the machine at the center of its bottom. The bearing of this main arm is such that water coming by the duct 2 is able to penetrate practically without leakage within the main hollow arm 1.
Near each end of the main arm 1 is located an injector 3 pivotely mounted on this main arm 1. This assembly is realized in such a way that the water introduced under pressure into the main arm 1 is able to be introduced in the injector 3 in order to be projected within the tank of the machine by the nozzles 4, 5, disposed in the vicinity of the ends of the injector 3. The nozzles 4 are directed upwardly and obliquely so as to provide the horizontal component of force which drives, through reaction, the injectors in rotation.
It is to be noted that the inclination of the nozzles 4 are such that the injectors 3 is driven in rotation in reverse sense the one from the other.
One of the injectors 3 comprises at one of its ends a nozzle 5 directed vertically upwards as well as a lateral noule 6.
The main arm 1 comprises also noales 7 at each of its ends to drive it in rotation through reaction.
The rotative assembly of each injector 3 on the main arm 1 is as follows:
The injector is fast with a hub 8 fixed on its lower and upper walls 9 and 10. This hub is provided with self-lubricating bearings 11. An axle 12 is fixed on the upper wall 13 of the main arm I and extends upwardly crossing the two bearings 11 of the hub 8 and emerging from the upper bearing 11. A cup 14 is fastened on the upper end of this axle 12 so that its axial and angular position will be fixed with respect to this axle 12. A certain play is provided between the upper bearing 11 and this cup 14 to permit a free rotation of the injector 3.
Holes 15 are provided in the upper wall 13 of the arm 1, disposed around the axle 12, corresponding to holes 16 provided in the lower wall 9 of the injector and located around the hub 8. In this manner water can pass from the arm 1 into the injector 3.
A joint is provided to avoid too heavy water losses between the arm 1 and the injector 3. This joint comprisesa circular flange 17 fast with the lower wall 9 of the injector and surrounding the holes 16 as well as a ring 18 for example of plastic material, located between the injector 3 and the arm 1 around the axle 12. The outside diameter of this ring 18 is slightly less than the internal diameter of the flange 17 but its internal diameter is at least suficient to encircle all the holes 16 and 15. The height of this ring 18 is slightly less than the distance separating the walls confronting each other of the injector 3 and the arm 1 so that this ring will be freely located.
To avoid that in operation the water pressure displaces axially the injector 3 against the cup 14 and causes thus an abnormal wear, the assembly of the injector comprises a thrust compensating device constituted by passages 19 located around the hub 8, provided in the upper wall 10 of the injector. These pasages are disposed within a periphery having a smaller diameter than the cup 14.
A sealing joint between the cup 14 and the injector 3 is constituted by a ring of plastic material 20, similar to the ring 18, located with radial and axial clearance within the space comprised between the upper wall 10 of the injector 3 and the cup 14.
One creates thus in operation a water cushion between the cup and the injector which permits to balance the axial thrust to which this injector is subjected so that it will freely revolve.
A similar compensation device for the thrust due to the water pressure could be mounted on the pivoting axis of the main arm 1. However, in certain embodiments where the water pressure is not to high, comprised between 0.2 and 0.7 atmosphere, the weight of the assembly of the rotor and the reaction of the water jets expelled by the injectors suffices to balance the main arm 1 and a conventional bearing may be used.
In a variant shown in FIG 5, the shafi 12 of the pivoting device of the injector 3 on the main arm 1 is mounted on the lower wall 21 of the arm 1. The tightnem as well as the balance of the injector 3 are realized in the manner described herebefore. This variant has the advantage of a very great passage section for the water from the arm 1 towards the injector, in efiectthis pasage is constituted by a circular passage 22 concentric to the hub 8 provided in the upper wall 13 of the arm I as well as by a similar passage 23 provided in the lower wall 9 of the injector.
It is to be noted that during operation the central arm revolves in the direction of the arrow a, one of the injectors 3 revolves in the same direction according to the arrow 0, whereas the other injector 3 revolves in the opposite sense b.
In this manner one obtains difierent sweeping speeds for the water jets emitted by the difi'erent injectors which increases the washing action and which above all tends to render without importance eventual speed variations of the rotation of the main arm 1 due to pressure variations of the water. It is to be noted that the direction of rotation of the injectors 3 is determined by the direction of inclination of the nozzles 4.
As seen hereabove, due to its vertical nozzle 5, the rotor described is particularly well adapted for the washing of industrial glassware having small necks.
When it is necessary, however, to wash glassware with very narrow necks the performance of this rotor may be increased by the use of an accessory shown in the variant of FIGS. 6 and 7.
In this variant the rotor is provided with a rod 25 connecting the main axle 24 to the vertical noale 5. This rod 25 is simply provided at each of its ends with a hole intended to receive the one the nozzle 5 and the other axle 24. In this way the vertical jet emitted by the nozzle 5 describes in operation a circle of a determined diameter d and it suflices to place the glassware, having a very narrow neck v, so that its opening will be aligned vertically on this diameter d. In effect, in that way it is ensured that the jet emitted by the noule 5 penetrates this glassware.
Furthermore as in this position the injector is locked, its nozle 4 which is oblique counteracts the effect of the noule 7 of the main arm 1 which then revolves more slowly which still enhance the washing action of the jet emitted by the vertical nonle 5.
Finally it is to be noted that in modifying the position of the locked injector for example in varying the length of the rod 25, the slowing down action of the nozzle 4 is modified the lever arm of its action is modified. In modifying the length of the rod 25 or in choosing a rod 25 of a determined length from among a series of rods which are at one's disposition, it is thus possible to vary the speed of rotation of the main arm 1 and thus the efficiency of the jet emitted by the vertical nozzle 5.
It is evident that numerous other variants of the rotor could be provided without departing from the scope of the attached claims. Particularly, the rings 18 and 20 could be provided with a slot or with a groove 26 (FIG. 3), provided in its internal peripheral wall, in order to permit the evacuation of wastes between the ring 18 and the flange 17 or between the ring 20 and the cup 14. In variants, this groove 26 could be replaced by a recessed formation provided in the internal peripheral walls of the cup 14 and of the flange 17.
