    [0001] ADJUSTABLE ROLLER CRIBE FOR CLEANING MACHINES AND WASHING MACHINES
    [0002]
    [0003] OBJECT OF THE INVENTION
    [0004]
    [0005] The invention, as expressed in the title of the present specification, refers to an adjustable roller screen for cleaning and washing machines of fruit and vegetable products that provides, to the function for which it is intended, advantages and novelty characteristics, which are described in detail later, which suppose an improvement of the current state of the art.
    [0006]
    [0007] More specifically, the object of the invention focuses on a screening apparatus for cleaning and washing machines of fruit and vegetable products, such as olives and almonds or others, which is distinguished by incorporating a system for regulating the separation between the rollers, thanks which, with a simple maneuver that is done by turning a wheel, can be achieved, quickly and easily, modify the distance between roller and roller to the desired and adapted to the circumstances of the product, taking into account that the distance between rollers of all the tandem will be the same, that is, if the hole first has a certain separation, the last gap and the intermediate holes will all have the same separation.
    [0008]
    [0009] FIELD OF APPLICATION OF THE INVENTION
    [0010]
    [0011] The field of application of the present invention is part of the agricultural sector, specifically in the field of industry dedicated to the manufacture of machines, devices and devices for cleaning and washing of fruit and vegetable products and more specifically focused on screening devices.
    [0012]
    [0013] BACKGROUND OF THE INVENTION
    [0014]
    [0015] Currently, it is used as a screening system for cleaning and washing machines for olives, almonds and other horticultural products, roller screens. These screens are formed by a tandem of rollers separated from each other a certain distance and that they aim to separate the waste product, mainly in the form of land.
    [0016]
    [0017] These screens have a problem when the product to be sifted changes size due to weather conditions or even due to the own variable size of the product itself, depending on the large number of varieties that exist in all these horticultural products.
    [0018]
    [0019] At present, no system has been incorporated into the roller screens used in the different brands of cleaning machines, allowing instantaneous regulation of the separation between rollers. Until now, the only way to vary this separation between rollers is to supply the customer with several frames with different separations, with the complication that this entails, in addition to the cost of labor and time spent making these changes to the frame.
    [0020]
    [0021] The objective of the present invention is therefore to solve said problem by developing an innovative screen with adjustable rollers, in order to be able to adapt the separation between them to the needs of each case immediately, easily and comfortably.
    [0022]
    [0023] On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of no other screen for said type of machines or any similar invention having some technical, structural and constitutive characteristics is unknown. equal or similar to those presented here claimed.
    [0024]
    [0025] EXPLANATION OF THE INVENTION
    [0026]
    [0027] The adjustable roller screen for cleaning and washing machines of horticultural products that the invention proposes is configured, therefore, as a novelty within its field of application, since according to its implementation and in a restrictive manner, the aforementioned objectives are satisfactorily achieved , the details that make it possible and distinguish it conveniently collected in the final claims that accompany the present description.
    [0028]
    [0029] More specifically, what the invention proposes, as pointed out above, is a screening apparatus specifically intended for incorporation as an element member of a cleaning and washing machine for olives, almonds or other horticultural products, presenting the particularity of having a means of regulating the separation between the rollers comprising, allowing, quickly and easily, to modify the distance between same for adapted to the needs and circumstances of the product in each case.
    [0030]
    [0031] To do this, and more specifically, the screen comprises, essentially, a fixed frame, where the axes of a plurality of parallel rollers are housed, at one end, which, instead of holes to receive said axes, as is usual Being conventional in existing screens, it has a longitudinal groove in almost the entire length of the frame that allows the lateral movement of the rollers.
    [0032]
    [0033] Parallel to this fixed frame and on the outside, and at the opposite end of the rollers, are what we will call adjustable frames. These adjustable frames, which have a series of grooves of increasing inclination in which the axes of the rollers are inserted on both sides, move in a single vertical direction thanks to a mechanism to which they are linked and which is actuated by means of a regulating steering wheel. .
    [0034]
    [0035] In particular, said mechanism of vertical movement of the adjustable frames is formed by two bars parallel to each other and to the rollers, which are responsible for transmitting the same movement to the adjustable frame on the right and on the left. These two bars are attached to the adjustable frames at their respective ends by means of a rack coupling to a vertical element which, in turn, slides in respective vertical slots of said frames, and in addition said bars are joined together by a bar perpendicular with respective transmission brackets provided at the ends of the same, existing in it, in addition, a regulation wheel with a worm-type reducer.
    [0036]
    [0037] Thus, the worm-gear reducer associated with the steering wheel has the purpose, on the one hand, to allow the position of the steering wheel (as indicated in drawings) does not prevent the visibility of the opening or closing of the space between rollers, since the described set of bars in which it is installed is located below the set of rollers, and on the other hand multiply the torque and thereby allow, with a light effort of the operator, the screen is regulated.
    [0038]
    [0039] Thanks to the position and design of the increasing inclination grooves of the adjustable frame, which on one side are completely vertical and gradually and regularly go acquiring greater inclination so that the lower end thereof is closer to each other than the upper end, allows the rollers all have the same separation from each other, and this separation varies when the adjustable frames move vertically, to be inserted the ends of the rollers in the described grooves of increasing inclination.
    [0040]
    [0041] In addition, at each end of the roller shaft a bearing has been fitted to fit into these grooves and also allows a smoother movement of the roller shafts.
    [0042]
    [0043] Preferably, a rule is attached to the adjustable frame that is located next to the steering wheel, which serves as an indicator of the opening of the holes between rollers, allowing to know at all times the separation between them.
    [0044]
    [0045] Additionally, to prevent the product from invading the ends where the functional elements of the screen and its mechanisms are located, for example the transmission, the incorporation of means for closing the separation spaces between rollers has been foreseen.
    [0046]
    [0047] More specifically, said closing means are determined by the existence of pieces that we have denominated "faldetas", since they hang as skirts of a profile or skirt frame arranged perpendicularly to both ends of the set of rollers. on each roller, so that, when the roller moves laterally, the skirt of its two ends in turn moves with it, for this the flaps have linear movement in the profiles from which they hang and a width such that they always remain overlapped with the adjoining one, so that there is never a free space between the rollers so you can introduce processed product no matter how small The skirt frame is fixed, but allows and guides the linear displacement of these flaps in line with the rollers.
    [0048]
    [0049] The described adjustable roller screen for cleaning and washing machines for horticultural products represents, then, an innovation of structural and constitutive characteristics unknown until now, reasons that together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is request

    [0065]
    [0066] PREFERRED EMBODIMENT OF THE INVENTION
    [0067]
    [0068] In view of the aforementioned figures, and in accordance with the numbering adopted, one can observe in them an example of non-limiting embodiment of the adjustable roller screen for cleaning and washing machines of horticultural products recommended, which comprises the parts and elements which are indicated and described in detail below.
    [0069]
    [0070] Thus, as seen in said figure 1, the screen (1) in question, comprising of known manner a set of rollers (2) parallel and coplanar, linked by each end to a fixed frame (3) and associated with a motor (19) that makes them rotate, is essentially distinguished, because said fixed frame (3) of each end has a longitudinal groove (4), which covers practically the entire length thereof, where the end of the axis of the rollers (2) is inserted allowing lateral movement of the same, end which, in turn, crossing said slot (4) of the fixed frame (3), is coupled, also at each end of the rollers (2), in an adjustable frame (5), parallel externally to the fixed frame (3), which, through a mechanism that it links it to a hand-actuated control wheel (6), it has a vertical movement with respect to the fixed frame (3) which determines the joint and equidistant separation of all the rollers (2), allowing it to be modified according to the needs of each product.
    [0071]
    [0072] For this, the two adjustable frames (5), associated with the fixed frames (3) by respective vertical slots (12), have a series of grooves of increasing inclination (7), the first being on one side completely vertical and the following , gradually and regularly, they acquire greater inclination, so that at the lower end the slots (7) are less separated than in the upper one, whereby, the vertical movement of the adjustable frames (5) determines the separation or grouping together and equidistant from the rollers (2).
    [0073]
    [0074] For said vertical movement of the adjustable frames (5), the mechanism provided is formed by two parallel bars (8) to each other and to the rollers, located at both ends of the set of rollers (2) and below them, which they are attached to said adjustable frames (5), at their respective ends, by means of a pinion (9) that engages in the rack (10) of a vertical element (11) which, in turn, is coupled to the adjustable frames ( 5). And, in addition, said parallel bars (8) are joined to each other by means of respective transmission brackets (13) provided at the ends with a perpendicular bar (14) to said parallel bars (8) where the adjustment wheel (6) is incorporated and to which they are connected with a reducer of the worm-crown type, so that the drive of the handwheel (6), through the worm gear reducer, determines that the transmission brackets (13) generate the rotation of the parallel bars (8). ) and, these, in turn, the displacement of the vertical elements (11) in the racks (10) with which the vertical movement is transmitted to the adjustable frames (5) to more or less separate the rollers (2).
    [0075]
    [0076] Preferably, as seen in the detail of Figure 2, at each end of the axis of the rollers (2) a bearing (15) has been fitted which fits into the increasing inclination grooves (7) of the adjustable frames (5) having a guide configuration for housing said bearing (15), thereby providing a displacement of the roller shafts (2) smoother.
    [0077]
    [0078] Also preferably, at least the adjustable frame (5) located next to the steering wheel (6), incorporates a rule (16) that acts as an indicator for opening gaps between rollers (2).
    [0079]
    [0080] Additionally, the screen (1) has means for closing the separation spaces between rollers (2) to prevent entry into the functional parts of the same and its mechanisms, for example the transmission, which, preferably, are determined by flaps (17) which, configured, as shown in Figure 6, to adjust to the contour of the roller (2), are incorporated at both ends of each roller (2) hanging from separate profiles (18), arranged perpendicular to both ends of the roller assembly (2) and as a guide, allow the lateral displacement of said flaps (17) when moving with the movement of the rollers (2) when the flywheel (6) is operated to modify the separation between them. .
    [0081]
    [0082] In addition, said flaps (17) have such a width that they always overlap with the adjoining one, so that there is never any free space between the rollers (2).
    [0083]
    [0084] Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages derived therefrom, stating that, within its essentiality, it may be carried out in other forms of realization that differ in detail from that indicated by way of example, and which will also achieve the protection that is sought provided that it is not altered, changed or modified its fundamental principle .
