    [0004] TECHNICAL SECTOR
    [0006] The present invention refers to a machine that enables the transport, alignment and inspection of the product, be it fruits and / or vegetables.
    [0008] The object of the invention is to offer a simple configuration integrated by at least one circuit that is provided with a plurality of rotating elements with a modifiable trajectory on which the product to be transported rests and where the rotating elements rotate their 360 rotation, to allow a complete inspection of the fruits and / or vegetables on them housed.
    [0010] BACKGROUND OF THE INVENTION
    [0012] The known transport systems for fruits and vegetables that are widely used in manual inspection benches or in machine vision sorting machines are based on a transport and turning system arranged below the artificial vision systems to facilitate their work. . Once the product to be transported has passed through the inspection area, the transport system continues throughout the entire machine, with its consequent greater weight, price and inadequacy to the individualized exit system that known machines have.
    [0014] In most of the known machines, the transport of the cups, rotating elements, cones or other elements specially adapted to the product to be transported, are coupled to a rigid chain or belt forming links. The aforementioned rigid chain is driven between two axes that, turning, generate its advance.
    [0016] One of the relevant drawbacks of the use of chains in known transport machines resides in the limitation of the degrees of freedom in the design of the circuit to be traversed.
    [0017] Due to all of the above, the applicant of the present patent application detects the need to develop a transport machine for fruits and vegetables that includes a drag element, which is not rigid, allowing a configuration that is easily adaptable to the size and shape of the product. transport.
    [0019] DESCRIPTION OF THE INVENTION
    [0021] The transport machine that is advocated in the present invention allows to solve the aforementioned problems, offering a mechanically simple and very efficient solution for the transport and processing of a product, be it fruits and / or vegetables.
    [0023] Advantageously, the machine has a high versatility to adapt to the size of the product to be transported and its configuration guarantees a minimum transfer height of the product between the inspection area and the exit belt.
    [0025] Specifically, the conveying machine of the invention has two differentiated zones, an alignment zone next to the product inlet and an inspection zone after the alignment zone.
    [0027] Thus, the transport machine is made up of, at least, the following elements:
    [0029] - At least one tow cable.
    [0030] - At least two crowns with notches, the crowns being associated in such a way that a trailing cable is arranged on them, defining at least one circuit through which it moves.
    [0031] - A plurality of rotating elements, where each rotating element is associated with a stud that passes through it to allow the rotation of the rotating element on the stud.
    [0032] - A plurality of connection elements, each connection element being provided with a perforation, a recess and a channel perpendicular to the perforation, so that the connection elements are suspended on the trailing cable through the perforations, each disposing connecting element associated with the channel of a shaft that supports the rotating element.
    [0033] - A machined rail arranged along one side of the circuit and where the machined rail has a clamp shape that is internally provided with projections and a friction strap, so that the recesses of the machined rail run through the projections of the machined rail. connecting elements and on the friction belt the rotating elements rest to generate the rotation on themselves.
    [0035] Advantageously, the assembly made up of the machined rail, the connection element and the stud provide rigidity and guide the movement of the rotating element in the horizontal and vertical axis, preventing the weight of the product from altering the position of the tow cable, making the product path located on the rotating element. In fact, the stud that is inserted in the rotating element constitutes its axis of rotation. Simultaneously, the rotating element rests on the friction belt located on the machined rail so that the friction of the surface of the rotating element with respect to the friction belt causes the rotation of the rotating element on itself.
    [0037] Thus, it should be noted that the point of contact of the rotating element on the friction belt determines the speed of rotation of the rotating element.
    [0039] Thus, the product advances by being supported between the rotating elements of the circuit associated with the trailing cable.
    [0041] The pair of notched crowns rotates defining the transport speed of the rotating elements suspended on the towing cable. Thus, the configuration of the machine of the invention makes it possible to independently modify the transport speed of the rotating elements - defined by the movement of the crowns associated with the towing cable - and the rotation speed of the rotating elements on themselves - defined by the point of contact of the rotating element on the friction belt of the machined rail and the travel speed of the friction belt.
    [0043] On the other hand, in the alignment area of the machine of the present invention, there are at least two moving belts. Each of the aforementioned belts is located facing each other and forming a V, the angle of inclination of the belts can be adjusted according to the needs of the product to be transported.
    [0044] Conveniently, the speed of movement of the belts is less than the transport speed of the rotating elements, that is, the V belts advance at a lower speed than the transport speed of the rotating elements, ensuring that a rotating element is will position a single product at all times.
    [0046] After the alignment zone, the product reaches the inspection zone. Since the products to be transported will be of different colors, it is convenient for the product to stand out from the background and on the rotating elements, for which the present invention recommends the implementation of rotating elements made up of a translucent material, which will be illuminated in the Inspection area by LEDs preferably of selectable color. These LEDs are located on the mechanized rail facing the rotating elements so that the light when penetrating them is refracted, illuminating the rotating element internally, thus allowing the proper selection of the color of the rotating element, facilitating the individualization of the product by the inspection persons or equipment that can be placed on the machine object of the invention.
    [0048] After the inspection zone, the rotating elements that transport the already inspected product vary their trajectory by modifying, within the machined rail, the footprint that guides the connection elements, at the same time that the position of the crowns and the trailing cable decreases. associated with them.
    [0050] Thus, the position of the crowns, the footprint of the machined rail and the trailing cable make it possible for the trajectory of the rotating elements to descend to approach a subsequent conveyor belt - which is not the object of protection - and which is arranged in the exit area of the machine of the invention.
    [0052] That is, the rotating elements are kept in a horizontal position - that is, with the axes of rotation parallel to the ground - during the advance through the alignment zone and the inspection zone of the machine, while in the exit zone of the machine. machine in which the machined rail is no longer present, the position of the rotating elements is modified, descending and where their axis of rotation is no longer horizontally positioned with respect to the ground, so that the transported fruit can be gently guided to a subsequent belt .
    [0053] Optionally, the machine of the invention can have two circuits defined by pairs of notched crowns and two trailing cables. In this embodiment, the two circuits move in the opposite and synchronous direction, leaving the rotating elements of each circuit arranged opposite each other, as will be detailed in the second preferred embodiment.
    [0055] The advantage of the configuration of the machine of the invention resides in the ability to adjust the position in terms of the distance between the pair of crowns that define the circuit or trajectory of the rotating elements suspended in the trailing cable. Likewise, this peculiarity enables the machine of the invention to be adaptable to offer a greater distance between each circuit when it has two circuits, favoring the transport of a greater range of diameters or lengths of product to be transported.
    [0057] Finally, it should be noted that the configuration of the transport machine of the invention facilitates the replacement of the rotating elements with ones of a different size through easy operation. Thus, each rotating element can be removed and replaced by others of a larger or smaller size as appropriate, inserting the appropriate number of rotating elements at the appropriate distance to the product to be transported, in this way the present invention allows increasing the separation between the rotating elements. of a circuit, with which the range of transportable products becomes very wide, being a very competitive solution with respect to other known machines of rigid transport circuits by guided chain.

    [0081] PREFERRED EMBODIMENT OF THE INVENTION
    [0083] Figures 1 and 2 represent the first preferred embodiment of the invention, while Figures 3, 4 and 9 represent the second preferred embodiment of the transport machine object of the present invention.
    [0085] In view of Figures 1 and 3, we can see that in any of the preferred embodiments, the machine is made up of a structure that rests on a support (15).
    [0087] Figures 2 and 4 represent a top view of the machine of the invention in its first and second preferred embodiments, respectively, where the entry area of the fruit and / or vegetables to be transported - product (10) - is identified, the area alignment (8) and inspection area (9).
    [0089] In any of the preferred embodiments of the transport machine for fruits and vegetables of the invention, a plurality of rotating elements (1) and a plurality of connecting elements (4) intervene.
    [0091] As seen in the first preferred embodiment of the invention - Figures 1 and 2 -, the machine is provided with a tow cable (2) and two crowns (3) with notches. Thus, the crowns (3) are associated in such a way that a towing cable (2) is arranged on them, defining a circuit through which said towing cable (2) travels.
    [0093] On the other hand, in the second preferred embodiment of the invention - Figures 3 and 4 -, the machine is provided with two trailing cables (2) and four crowns (3) with notches. In this way, the notched crowns (3) are associated in pairs, so that on each pair of crowns (3) one of the trailing cables (2) is arranged defining a circuit. That is, the second preferred embodiment of the machine of the invention has two circuits associated with two trailing cables (2), respectively, which move in the opposite direction and synchronously, as indicated in figure 3.
    [0095] Advantageously, the second embodiment of the invention makes it possible to modify the distance between the two opposite circuits, whereby the range of transportable products becomes very wide.
    [0097] Figure 5 represents a connection element (4) that intervenes in any of the preferred embodiments of the invention and preferably having a T-shape. Each connecting element (4) is provided with a perforation (4 '), a recess (4'') and a channel (4''') perpendicular to the mentioned perforation (4 ').
    [0099] As can be seen in Figure 6, in any of the preferred embodiments of the invention, the preferred shape presented by the rotating element (1) is a cone. Thus, each rotary element (1), regardless of the external shape adopted, is associated with a stud (5) that passes through it to allow the rotation of the rotary element (1) on the stud (5). Likewise, Figure 5 makes it possible to observe that a trailing cable (2) is inserted through the perforation (4 ') of the connection element (4).
    [0101] From Figures 6 and 7 it can be seen that, in any of the preferred embodiments of the invention, the connection elements (4) are suspended on the trailing cables (2) through the perforations (4 '). Thus, each connecting element (4) is associated with the channel (4 '') of a rotating element (1) by means of the stud (5). Therefore, the machine of the invention is provided with the same number of connection elements (4) as of rotating elements (1).
    [0103] On the other hand, the notch (4 '') of the connection element (4) enables it to be associated with a machined rail. Specifically, the first preferred embodiment of the machine of the invention is provided with a machined rail (6) by presenting only one circuit. This machined rail (6) is arranged along one side of the circuit as seen in Figures 1 and 2.
    [0105] On the other hand, the second preferred embodiment of the invention has machined rails (6) arranged in the two circuits facing each other.
    [0107] Figure 8 shows that in any of the preferred embodiments of the invention, each machined rail (6) has a clamp shape that is internally provided with projections (6 ') and a friction strap (7), so that the notches (4 '') of the connection elements (4) run through the projections (6 ') of each machined rail (6) and the rotating elements (1) rest on the friction belt (7) to generate the rotation about themselves.
    [0108] In both preferred embodiments of the invention, in Figures 2 and 4, the alignment zone (8) of the machine is provided with at least two moving belts (11), each one located opposite each other forming a V and its presence being limited to the alignment zone (8). In both preferred embodiments, the angle of inclination formed by the V belts can be adjusted according to the needs of the product to be transported.
    [0110] To understand the movement provided to the product (10) to be processed through any of the preferred embodiments of the machine of the invention, it should be noted that each pair of crowns (3) moves defining a transport speed of the rotating elements (1 ) suspended on the trailing cables (2) of the circuit. In this way, the speed of movement of the belts (11) is lower than the transport speed of the rotating elements (1) to offer a surface where the product (10) accumulates.
    [0112] Advantageously, in the second preferred embodiment of the invention, the presence of the V-shaped tapes (11) offer a larger surface where the product (10) can be accumulated in order to favor its correct alignment and ordering and then move on to the inspection area (9).
    [0114] Optionally, in any of the preferred embodiments of the invention, the mechanized rail (6) in the inspection area (9) is provided with LEDs (14) which project lighting onto the rotating elements (1) that are optionally integrated by a translucent material. In this way, a contrast is generated between the products (10) and the illuminated translucent rotating element (1), this contrast being even more intense as the rotating elements (1) are made of a translucent material. Advantageously, the presence of complementary vision means - not represented in the figures that accompany the present specification - in the inspection area (9) facilitates the capture and analysis of images to verify the status of the product (10) transported through the machine of the invention.
    [0116] On the other hand, it should be noted that in any of the preferred embodiments of the invention, the friction belt (7) defines a path along the internal surface of the machined rail (6). As seen in figure 8, the friction belt (7) is optionally located on said internal surface of the machined rail (6) in different positions. Specifically, the friction belt (7) is further from the edge (6 '') in the alignment zone (8) and is closer to the edge (6 '') of the machined rail (6) in the inspection zone ( 9). In this way, the change of position of the friction belt (7) along the internal surface of the machined rail (6) modifies the speed of rotation of the rotating element (1), by changing the support point of the belt friction (7) with respect to the surface of the rotating element (1). Thus, the speed of rotation of the rotating element (1) will be lower in the inspection area (9) since the friction belt (7) comes into contact with the rotating element in a larger diameter area, so optionally in In the second preferred embodiment, different paths of the friction belt (7) located inside each machined rail (6) will correspond to different angular speed for each rotating element (1) with respect to its opposite counterpart (1), making it possible in the same point of advancement of the product (10) that the rotating elements (1) rotate at different angular speeds causing the product (10) to additionally rotate on itself.
    [0118] Finally, figure 9 represents in detail the output of the product (10), be it a fruit or a vegetable, in the second preferred embodiment of the invention after processing. This figure shows the two circuits formed by two trailing cables (2) associated with two pairs of crowns (3) with notches and that the processed product (10) runs between the two circuits defined by the set of crowns (3) with notches and the tow cables associated with a plurality of rotating elements (1).
    [0120] Thus, the product (10) comes into contact with the outer surface of the rotating element (1), which is in a continuous rotation and favors the advance and rotation of the product (10) through the alignment zone (8) and the inspection zone (9) until its exit from the machine, as represented in figure 9.
    [0122] Finally, it should be noted that, in any preferred embodiment of the invention, the tow cables (2) are preferably made of steel.
