DETAILED DESCRIPTION

[0086] With reference to the accompanying drawings, a washing device is indicated as a whole by 1, while the washing machine 100 is indicated as a whole by 100.

[0087] It should be noted that for the purposes of the present invention, the term “washing” may be understood also as a “rinsing” process according to the intensity of the jet, to the composition of the washing fluid and to the washing logic.

[0088] In particular, device 1 of the present invention is configured to wash (and/or rinse) objects 50 for stalling laboratory animals, in particular, parts and/or accessories of stalling cages (hereinafter simply objects 50 for descriptive simplicity) having respective surfaces 51 to be washed. The surfaces 51 to be washed here define the surfaces of the objects 50 requiring a particular (washing and/or rinsing) process/treatment to remove the dirt and impurities which accumulated during normal use. Reference in particular is mainly made to the surfaces which, during use of the objects 50, are exposed to direct contact with the laboratory animals and their waste.

[0089] In particular, the following description refers to concave surfaces 51 to be washed, or more simply, concavities 51, to better clarify and highlight the advantages of the invention with respect to the known art, without for this the invention having to lose in generality.

[0090] In particular, the device is configured to thoroughly wash at least the concave surface of such objects 50, that is, that surface portion of the concave object 50, which for simplicity, is indicated as “concavity” 51.

[0091] Device 1 comprises at least one rod 2 extending along a main axis X and connectable to a source of pressurized washing fluid (not shown in the accompanying drawings).

[0092] Device 1 further comprises fluid conveying means connected to said source of pressurized washing fluid and associated with rod 2: such fluid conveying means may be made with any technology or structure of the known type.

[0093] Device 1 then comprises a plurality of nozzles 3 adapted to emit respective jets of said washing fluid, in which the plurality of nozzles 3 is connected to the aforesaid fluid conveying means and therefore, is supported by rod 2.

[0094] In a possible embodiment of the invention, rod 2 is hollow, and this means that the fluid conveying means comprise at least one conduit extending inside the hollow rod 2 itself, and therefore the plurality of nozzles 3 is in fluid communication with such a conduit.

[0095] The term “hollow” indicates the presence of a conduit inside rod 2 (shown in FIG. 2A), which is connectable or connected in fluid communication with the source of pressurized washing fluid.

[0096] Within the spirit of the present invention, the term “axis” may be considered as any ideal progress in space in terms of geometrical development of a structural element and/or in terms of possible roto-translational movement (or in other words, of any trajectory) of such a structural element, without departing from the objects of the invention itself and without limitations to the interpretation of the claims appended herein.

[0097] Each rod 2 has a plurality of nozzles 3 adapted to emit respective jets of the washing fluid.

[0098] Preferably, the jets emitted by the nozzles have a conical shape (that is, the spray is of the conical type) or conical cross section, however the shape of the jet may be selected according to the type of concave object and the type of wash to be performed.

[0099] Preferably, in the embodiment shown in the accompanying drawings, rod 2 has two separate and concentric inner ducts belonging to different manifolds connected to different washing fluids and there may be nozzles 3 on the same rod 2 which alternately dispense a first fluid and a second fluid.

[0100] Device 1 advantageously comprises both translation means 4 of rod 2 and rotation means 5 of rod 2.

[0101] The translation means 4 are configured to translate rod 2 along a translation stroke z extending along a translation axis Z, which is transversal, preferably perpendicular, to the main axis X.

[0102] In other words, rod 2 is translatable along a rectilinear trajectory defined by the translation stroke z (shown in FIG. 2).

[0103] Preferably, the translation means 4 comprise a screw and nut mechanism 4a (shown in FIG. 3), however other known mechanisms which perform the same function may be used.

[0104] The screw is put into rotation by suitable actuation: the type of actuation may be of any kind (electric by means of gear motor, pneumatic, hydraulic) and is not part of this invention given that it is a known system.

[0105] The rotation means 5 are configured to alternately rotate the at least one rod 2 about a rotation axis R parallel to the main axis X inside a rotation angle γ, as indicated in FIG. 2A.

[0106] With particular reference to the embodiments shown in the accompanying drawings, the rotation axis R preferably is coincident with the main axis X; however, according to a possible embodiment not shown in the accompanying drawings, the rotation axis R could be arranged eccentrically with respect to the main axis X.

[0107] Preferably, the rotation angle γ has a value between 0° and 150°, even more preferably, it is equal to 75°.

[0108] In other words, as diagrammatically shown in FIG. 2, each rod 2 may translate in the direction indicated by arrow F1 and rotate in the direction indicated by arrow F2.

[0109] Therefore, the translation means 4 and the rotation means 5 advantageously are selectively operable according to a predetermined logic (that is, predetermined by the user or predetermined following given detections, as is more apparent in the description below) to move the at least one rod 2 inside an operating plane XZ defined by the main axis X and the translation axis Z.

[0110] Thereby, during a use configuration of device 1 in which the jets of washing fluid are emitted from the nozzles 3 and the objects 50 are operatively facing the operating plane XZ with the respective concavities 51 facing the at least one rod 2, the jets of washing fluid can be directly emitted against the concavities 51 to wash them thoroughly.

[0111] In other words, one or more translations and/or rotations of rod 2 may be controlled so that rod 2 is arranged in one or more predetermined positions inside the operating plane XZ so that the emitted jets can strike, that is they are directed, and thoroughly wash each concavity 51 of the objects 50 in a cyclical manner and according to determined washing criteria (wash time, cycle number, jet flow rate, etc.).

[0112] With particular reference to the embodiment of device 1 illustrated in the accompanying drawings, device 1 preferably comprises two parallel rods 2 lying inside the same operating plane XZ, even more preferably, mutually constrained in the translation along the translation stroke z. In other words, the two rods 2 move with a synchronous translation, while they may rotate independently or dependently according to the washing needs.

[0113] Two rods indeed are a balanced solution for meeting both the cost parameters and dimensions of device 1.

[0114] With particular reference to the embodiment of device 1 illustrated in the accompanying drawings, further preferably the operating plane XZ is vertical, the translation axis Z is vertical, and the main axis X is horizontal.

[0115] In other words, the translation of rod 2 is vertical and is carried out from the top downwards and vice versa; however, for example, also the horizontal translation whereby the translation could be carried out from left to right and vice versa, falls within the inventive concept of the invention.

[0116] Preferably, the rotation means 5 comprise an inclination switch 5a configured to reversibly switch the inclination of the at least one rod 2 between a first angular switching position P1 and a second angular switching position P2.

[0117] In particular, as shown in the example in FIG. 2A, the first angular switching position P1 corresponds to a first angle of inclination α of rod 2 (and therefore of the direction of the jet of washing fluid) with respect to a neutral (or middle) plane XY perpendicular to the operating plane XZ, while the second angular switching position P2 corresponds to a second angle of inclination β of the rod with respect to the neutral plane XY, said angular switching positions preferably being opposite to said neutral plane XY.

[0118] In particular, the neutral plane XY preferably is horizontal.

[0119] In particular, the switching between the two angular switching positions P1, P2 may be carried out progressively or instantaneously, and may be dependent or independent on a translation motion along stroke Z, as apparent below.

[0120] Preferably, the first angle of inclination α is between 0° and 75°, and even more preferably it is equal to 50°, while the second angle of inclination β preferably is between 0° and 75°, and even more preferably it is equal to 25°.

[0121] Moreover, the sum between the first angle of inclination α and the second angle of inclination β preferably is equal to the rotation angle γ, whereby the two angular switching positions P1, P2 are the end positions of the arc of rotation/oscillation of rod 2.

[0122] Moreover, the angular switching positions P1, P2 preferably are associated with respective inversion positions of the translation direction, preferably corresponding to mutually opposite ends of the translation stroke z.

[0123] In other words, the switching of the inclination of rod 2 preferably may be carried out at the same time as the inversion of the translation direction, in particular even more preferably, it may be carried out at the stroke end positions of rod 2.

[0124] According to a first embodiment of the rotation means shown in FIGS. 4A and 4B, the inclination switch 5a preferably comprises a flexible element 5b in the form of a chain, arranged parallel to the translation axis Z, and a coupling tooth 5c which is integral with rod 2 and configured to be reversibly coupled between the pins of chain 5b. When rod 2 translates along a first translation stroke z1, for example downwards, rod 2 remains inclined about the main axis X of the second angle of inclination β (that is, it is in the second angular position P2) since, by virtue of the elasticity/flexibility of chain 5, the coupling tooth 5c is shaped so as to pass in sequence between the pins of chain 5 without ever getting blocked. However, when the translation direction is inverted, that is rod 2 is translated along a second translation stroke z2 opposite to the first translation stroke z1, this time upwards, the coupling pin 5c remains coupled between two consecutive pins and induces the rotation of rod 2 until the inclination of rod 2 is switched from the first angular position P1 to the second angular switching position P2.

[0125] That is, rod 2 is rotated about the main axis X by a rotation angle equal to the sum of the first angle of inclination α and the second angle of inclination β.

[0126] In other words, the mechanical coupling described above determines, in the descending stroke, a negative angle of incidence which during the stroke inversion, is transformed into positive by virtue of the flexibility of the element.

[0127] The same effect may be obtained with the second embodiment shown in FIG. 5, in which the inclination switch 5a preferably comprises a fixed coupling notching 5d and a coupling pin 5e which is integral with rod 2, but oscillating, that is, provided with elasticity by means of springs (not shown). Indeed, the coupling pin 5e passes from one slot to another of notching 5d during the translation stroke z1, but when the direction of the translation stroke is inverted, the coupling pin 5e remains wedged inside a slot until the switching of the inclination of rod 2 occurs.

[0128] According to a third embodiment of the rotation means 5 shown in FIGS. 6, 6A and 6B, the rotation means 5 preferably comprise a linear actuator 5f, for example, a pneumatic cylinder, operable to move, along a sliding direction parallel to the translation axis Z: [0129] a pin 5g arranged parallel to the main axis X and inserted inside a coupling eyelet 5h which is integral with rod 2 (detail in FIG. 6A) to rotate rod 2 about the main axis X, or [0130] a pin 5g arranged parallel to the main axis X inside which there is inserted a radial tip 5i of rod 2 (detail in FIG. 6B) to rotate rod 2 about the main axis X.

[0131] Moreover, the linear actuator 5f preferably is mounted on a connection manifold 6 of the two rods 2, whereby it translates together with the two rods 2, but the actuation of the translation of the pins 5g inducing the rotation, preferably synchronous, of the two rods 2, remains independent.

[0132] According to a further aspect of the present invention, a washing machine 100 of objects 50 is provided, comprising: [0133] at least one washing device 1 according to the present invention, [0134] a sealed wash chamber 101 having at least one access door (not shown in the accompanying drawings for illustrative simplicity) and at least one washing wall 102 onto which at least one device 1 is installed, and [0135] at least one support device 110 configured to receive and support a plurality of objects 50 so as to arrange the respective surfaces 51 to be washed, during the use configuration, facing the operating plane XZ.

[0136] In particular, the sealed wash chamber 101 shown in FIGS. 1 and 2 has a substantially parallelepiped shape and has two vertical, parallel washing walls 102 facing and opposite to a front wall transversal to the two wash walls on which the access door is obtained, a rear wall opposite to the front wall, mutually parallel floor 103 and roof 104.

[0137] Preferably, the support device 110 is a movable trolley (it is provided with wheels in the illustrated example) adapted to be reversibly arranged inside the wash chamber 101 through the access door.

[0138] For illustrative simplicity, one upper row of objects 50 (in this case, they are bases of animal stalling cages) alone is arranged on trolley 110 illustrated in FIG. 1, while FIG. 2 illustrates an embodiment of trolley 110 in which there are arranged 7 vertically aligned horizontal rows of objects 50 (with the concavities 51 partially overlapping with respect to the horizontal) for each side of trolley 110.

[0139] Indeed, machine 100 preferably comprises at least two washing devices 1 defining two different, opposite and parallel operating planes XZ (defining the so-called opposite “benches” of machine 100) mounted on opposite washing walls 102 and between which said at least one support device 110 is interposed, or adapted to be interposed, in use. In particular, in the embodiment illustrated, each device 1 comprises two rods 2.

[0140] Moreover, machine 100 preferably comprises a plurality of sensors (not shown) configured to detect operating parameters of the plurality of objects 50, for example: number, type, shape, size, spatial arrangement with respect to the operating plane XZ, degree of surface dirt, and also type of load and/or trolley-support.

[0141] For example, machine 100 may detect the type of load and/or trolley-support by means of RFID, acquisition of bar code or other code.

[0142] Machine 100 further comprises a control and processing unit (not shown) configured to process the predetermined logic of device 1 as a function of the operating parameters detected and selectively control the actuation of the translation means 4 and the rotation means 5, and therefore, control the wash cycle.

[0143] In addition to allowing the complete coverage also in the case of row numbers greater than what is used in the prior art, machine 100 also allows dedicated and intelligent cycles to be carried out: with suitable programming of the control logic, partial washes by rows or by sectors may be obtained, or points of greater insistence of the wash jet towards the dirtiest areas and surfaces to be washed may be provided.

[0144] According to a further aspect of the present invention, a method for washing objects 50 is provided, comprising the steps of: [0145] providing at least one device 1 according to the present invention; [0146] providing a plurality of objects 50 on at least one support device 110 so that they are operatively facing the operating plane; [0147] selectively controlling the actuation of the translation and rotation of the at least one rod 2 according to a predetermined logic for moving the at least one rod 2 inside the operating plane XZ so that it faces the concavities 51 of the objects 50, and [0148] emitting a predetermined amount of jets of washing fluid from the plurality of nozzles 3 directly against the respective concavities 51 of the objects 50 in order to wash them thoroughly.

[0149] Advantageously therefore, as shown in FIG. 2B, the nozzles 3 being able to translate along the translation stroke z2 (upwards in the example shown) and being able to rotate about the main axis X (as shown by arrow F2), they can strike any point of the concavities 51 which are arranged facing the operating plane XZ. For example, FIG. 2B shows a nozzle 3 moved along stroke z2 to be arranged aligned at three partially vertically overlapping objects 50: the directions of the jets of washing fluid clearly indicate how each surface portion of the concavities 51 is reached without leaving “dead areas”, as in the solutions of the known art of FIGS. 0A, 0B. The translation and selective rotation of rod 2 allow the position of nozzle 3 to be adapted to be arranged in the optimal position to strike any point of the concavities 51.

[0150] Preferably, the control and emission steps of the fluid are carried out at the same time.

[0151] Preferably, the control step comprises a sub-step of switching the inclination of the at least one rod from the angular switching position P1 to the second angular switching position P2, and vice versa.

[0152] Preferably, the control step comprises a sub-step of translating the at least one rod 2 along the translation stroke z while inverting the translation direction at respective inversion positions of the translation direction, preferably corresponding to mutually opposite ends of the translation stroke.

[0153] Preferably, the switching of the inclination at the angular switching positions P1, P2 is obtained at the same time as the inversion of the translation at the respective inversion positions of the translation direction.

[0154] In other words, the control step may comprise for example: [0155] a first sub-step of translating the at least one rod 2 along a first translation stroke, preferably until reaching a first end of said translation stroke, [0156] a first sub-step of switching the at least one rod 2 between the first angular switching position P1 and the second angular switching position P2, [0157] a second sub-step of translating the at least one rod 2 along a second translation stroke in direction opposite to the first translation stroke, preferably until reaching a second end of the translation stroke, opposite to the first end, and [0158] a second sub-step of switching the at least one rod 2 between the second angular switching position P2 and the first angular switching position P1.

[0159] These washing modes advantageously allow a uniform wash cycle capable of also washing floor 103 and roof 104 to be carried out in order to avoid residuals of dirt or spatter from being accumulated over time.

[0160] Moreover, the inversion and switching points allow being effective in washing on the lower and upper rows also while limiting the translation stroke to what is needed.

[0161] In the event one rod 2 alone is employed, such a solution allows limiting the overall translation stroke z and, if several rods 2 are employed, operating them without overlapping, rather keeping a given dead area therebetween (which is useful for leaving part of the washing walls 102 of machine 100 free from the translation of the rods 2, which would preclude the mounting/passing of any other device on board the machine).

[0162] Preferably, the control step comprises a sub-step of oscillating the at least one rod 2 about the rotation axis R inside the rotation angle γ, in which the oscillation is preferably progressive until it reaches the first angle of inclination α of rod 2, and is preferably regressive until it reaches the second angle of inclination β of rod 2.

[0163] Preferably, the oscillation sub-step is obtained at the same time as at least one translation sub-step of the at least one rod 2 along the translation stroke z.

[0164] In other words, a possible operating mode is the one of roto-translating rod 2.

[0165] Preferably, the method may provide the simultaneous translation and/or the rotation of two rods 2 lying on the same operating plane XZ.

[0166] Moreover, as shown in the drawings, the respective concavities 51 of the objects 50 preferably are partially overlapping with respect to a neutral direction Y perpendicular to the operating plane XZ, and the concave objects are arranged along rows which are parallel to the operating plane XZ.

[0167] Indeed, by virtue of present invention, also increased load densities may be thoroughly washed, in which the objects 50 have partially overlapping arrangements (as shown in FIGS. 2 and 2B) to optimize the spaces on the support device 110. Similar load configurations cannot be employed with the known washing systems, but the present invention allows the correct management thereof by virtue of the versatility thereof.

[0168] As in the illustrated embodiments, the method preferably comprises a step of providing at least two washing devices 1 defining two different operating planes XZ, which are opposite and parallel to each other, between which a support device 110 is interposed, or adapted to be interposed, in use; said two washing devices 1 being preferably synchronously controllable.

[0169] Preferably, the method advantageously comprises a step of detecting operating parameters of the plurality of objects 50, for example, number, type, shape, size, spatial arrangement with respect to the operating plane XZ, degree of surface dirt, and a successive step of processing the predetermined logic as a function of the detected operating parameters for setting the control step. Thereby, the wash cycle may be completely customized according to the load needs and the detected degree of dirt. Thus, for example, the actuation alone of a given rod 2 may be controlled for a limited translation stroke z or the intensity of the jets may be increased or the wash cycle time may be decreased or the wash cycle and the rinse cycle may be modulated in a different manner.

[0170] By virtue of the present invention, it is apparent how by suitably selecting translation stroke z, distance between the rods 2, rotation angle γ and possible inversion/switching points, a complete coverage of the load may be obtained at the surfaces 51 to be washed, in particular, at the concavities, and at the same time the roof 104 and the bottom 103 of machine 100 itself may be struck, also in the presence of overlapping between the rows of objects 50.

[0171] It is also apparent from the diagrammatic example in FIG. 2A how such a result is possible by combining the two movements alone which allows coverage in otherwise unreachable areas (unless a remarkably high number of fixed jets is used, which would preclude the functionality and washing power of the system).

[0172] Moreover, by suitably configuring support 110, the drinking bottles, which usually are directed by employing dedicated baskets which retain them and present them for washing so as to make them draining, may also be conveniently washed and/or rinsed. Therefore, it is easy to effectively wash, and especially rinse, also the bottles by directly using the system described.

[0173] The washing and/or rinsing which may be obtained with the present invention is completely adaptable to the type of load by virtue of the versatility of device 1 and machine 100: for example, in the case of non-uniform loads or loads with different areas of dirt, a more accurate and dedicated wash may be programed by persisting more with the jets in certain areas of the objects 50. Moreover, half load cycles may be carried out (for example, loading only the upper or lower rows of machine 100), therefore creating targeted cycles which allow saving time and energy, as well as allowing increased flexibility in managing the load to be washed and/or rinsed.

[0174] The present invention reaches the proposed objects while overcoming the drawbacks of the known art and providing the user with a device 1, a machine 100 and a method for washing and/or rinsing which are highly versatile and efficient, capable of optimizing the washing process and making the production process more affordable in terms of energy consumption, detergents used, sizes and investments.

[0175] A single machine 100 having compact sizes allows to effectively process a large number of objects 50 provided with surfaces to be washed of any shape, in particular surfaces that can be defined with the term “sculptured”, and in particular concavities 51, and of different types, by means of at least one device 1, which is structurally simple.
