    [0004] OBJECT OF THE INVENTION
    [0006] The object of the invention is a fruit sizing device that is placed around it while it is on the tree, from when it has a very small diameter until it is picked. The device measures the data of the diameter or caliber of the fruit and sends it by radio frequency to an external device, allowing the updated data to be known at all times.
    [0008] BACKGROUND OF THE INVENTION
    [0010] Currently, the fruit is collected, selected, treated and classified according to its size, that is, according to its maximum diameter. In most cases, this determination of the characteristics is made once the fruit has been picked, which in many cases entails having to discard some because they have been picked too early, when they have not yet reached the appropriate size, or well too late, when they have a higher caliber than desired.
    [0012] On the other hand, it is of interest to know at all times what is the development of the fruit in different trees, in order to make decisions regarding the management of the trees, in terms of irrigation, fertilization, etc.
    [0014] To try to solve the two previous points, a series of calibration devices have been developed over time that are placed directly on the fruit, usually surrounding it, when it is still on the tree, and since it is very small, thus achieving to know the development of the fruit through its size. However, these devices have a number of disadvantages that are described below.
    [0016] First of all, these devices, which are placed hugging the fruit by its larger diameter, damage the outer skin, which is extremely delicate. In addition, they exert high pressure that can affect the growth of the fruit, deforming it.
    [0017] On the other hand, they are devices of high weight, so that on many occasions the fruit falls to the ground, it is no longer usable, with the economic losses that this entails.
    [0019] Lastly, the devices developed so far are mainly mechanical devices, which are not capable of transmitting the fruit size information in real time to the farmer, so that the farmer cannot use it to his advantage.
    [0021] In fact, when using these devices and if you want to know the size of the fruit, it is necessary to go to look at it in the device itself, something that is extremely uncomfortable in the case that a large number of these devices have been placed in the various trees.
    [0023] DESCRIPTION OF THE INVENTION
    [0025] The device object of the present invention allows solving the problems raised in the background of the invention.
    [0027] In particular, the tree fruit sizing device is a device that, due to its structure, adapts perfectly to the contour of the fruit, from when it has a small diameter of about 20-25 millimeters, until it increases in size and it is time to pickup. This structure makes it possible to precisely determine the size of the fruit, but without damaging the delicate outer skin, much less causing it to become deformed.
    [0029] On the other hand, as the structure of the device is light, it does not cause the fruit to fall, even under adverse weather conditions, rain or wind, as the added weight is very low. Furthermore, the device comprises a protection compartment inside which the necessary electronics are located, so that it is protected against water, dust, or any other external element. In fact, the device is very compact and maintenance-free.
    [0031] Lastly, the device has the important advantage that it has means of communication that allow the information on the size of the fruit to be known and transmitted to an external device at all times. In addition, the reception of the data obtained by at least 3000 or 4000 devices can be coordinated at the same time. In this way, it can be obtained, at real time, tremendously useful information on the state of the fruit, which can be used for decision-making.
    [0033] Specifically, the tree fruit sizing device comprises a lower annular disk, which has an interior compartment and a guide around its perimeter, capable of rotating on itself in one direction. First flexible arms of curved configuration start internally from the lower annular disk, each first flexible arm ending at an inner end, which together with the inner ends of the other first flexible arms define a lower opening destined to house the fruit. Said inner end has a first hole.
    [0035] On the lower annular disk, an upper annular disk is positioned, parallel to the lower annular disk, with the ability to rotate on itself, in the opposite direction to that of the lower annular disk. Second flexible arms depart internally from this second disc, each ending at an inner end, which together with the inner ends of the other second flexible arms define an upper opening destined to house the fruit. Said inner end has a second hole.
    [0037] The upper annular disc has a first fixing element on the face facing the lower annular disc.
    [0039] Both the set formed by the lower annular disk and the first flexible arms, as well as the one formed by the upper annular disk and the second flexible arms have a similar operation to that of the diaphragm of a photographic camera, so that, as the fruit grows, the first flexible arms and the second flexible arms contract, drawing closer and closer to the lower annular disk or the upper annular disk, as appropriate.
    [0041] The device also comprises at least one bolt, attached to the upper annular disk, intended to move through the guide when the upper annular disk rotates with respect to the lower annular disk, keeping the lower annular disk and the upper annular disk together and allowing the movement of one with respect to the other.
    [0043] The device also comprises means for connecting the arms, for connecting the first hole of a first flexible arm and the second hole of a second flexible arm being coincident.
    [0044] In one embodiment, these means of joining the arms can be contact pieces, intended, in addition to joining a first flexible arm with a second flexible arm, to remain in contact with the fruit at all times, without moving with respect to this, and they are the ones that transmit the force to the flexible arms, which leads to the rotation of the annular discs, as the fruit grows. These joints are made through holes built in the ends of the arms (3 and 3 ').
    [0046] Each of these contact pieces adapts independently to the contour of the fruit, ensuring maximum grip, regardless of how irregular its contour is.
    [0048] Alternatively, the means for attaching the arms can be adhesive means, so that each of the first flexible arms is adhered to its corresponding second flexible arm.
    [0050] As the fruit increases its diameter, the first flexible arms and the second flexible arms move closer and closer to the upper ring disc and the lower ring disc, as appropriate. This causes the upper ring disc and the lower ring disc to be forced to rotate on itself.
    [0052] As the first flexible arms and the second flexible arms are arranged in oppositely curved configurations, the rotation of the upper annular disc and the lower annular disc will occur in opposite directions. By measuring the relative displacement that occurs when one annular disk rotates with respect to another, it is possible to determine the growth of the fruit at all times, and therefore its size, which is the data of main interest in this case.
    [0054] Inside the inner compartment, there are second fixing elements, associated with the first fixing elements of the upper annular disk, and they are intended to move through the inner compartment.
    [0055] Inside the interior compartment there is a reading system, with a first reading element, associated with the second fixing elements, and a second reading element, positioned in the interior compartment. In this way, the first reading element is associated with the upper annular disk and the second reading element is associated with the lower annular disk. By rotating one disk with respect to another, the reading system is able to measure the relative displacement of one disk with respect to another.
    [0056] The first reading element can be associated reading pins connected to a plate associated in turn with the second fixing elements. These pins are located in correspondence with the second reading element and are those that measure the displacement of the upper annular disk with respect to the lower annular disk. The second reading element can be a coded arc.
    [0058] Finally, in the interior compartment there are also communication means destined to send the measurement obtained by the reading system to an external device, as well as one or more batteries for powering the device.
    [0060] In an embodiment of the invention, the device may comprise a protection disc, positioned on the inner compartment of the lower annular disc. In this way, the electronic components positioned in the interior compartment are protected.
    [0062] In this embodiment, both the first fixing element associated with the upper annular disc, and the second fixing element associated with the lower annular disc are magnets, associated by a magnetic force. In this way, when the upper annular disk rotates, it drives the magnet of the first fixing element integrally. In turn, this magnet draws the second magnet of the second fixing element through the protection disk. This magnet of the second protection element, associated with the plate and therefore with the first reading element, moves it over the second reading element, as indicated above.

    [0085] PREFERRED EMBODIMENT OF THE INVENTION
    [0087] An embodiment of the present invention is described below with the aid of FIGS. 1 to 9.
    [0089] In figure 1, the fruit-on-tree sizing device is shown, positioned around an apple on the tree.
    [0091] As can be seen in said figure, and in more detail in figure 2, the device comprises a lower annular disk (4) with the ability to rotate on itself, and which has an interior compartment (11) and a guide (12) around its perimeter. The guide (12) can be seen in more detail in figure 6.
    [0093] First flexible arms (5) with a curved configuration start internally from the lower annular disk (4), which end at an inner end, which together with the inner ends of the other first flexible arms (5) define a lower opening (18) destined to house the fruit. Said inner end has a first hole (3).
    [0094] Furthermore, the device comprises an upper annular disk (1), shown in figure 7, parallel to the lower annular disk (4) and capable of rotating on itself in the opposite direction of rotation to the lower annular disk (4). Second flexible arms (2) with a curved configuration start internally from the upper annular disk (1), and which end at an inner end, and which together with the inner ends of the other second flexible arms (2) define an upper opening (19 ) destined to house the fruit. Said inner end has a second hole (3 ').
    [0096] The upper annular disk (1) has first magnets (13) on the face facing the lower annular disk (4).
    [0098] As it appears in Figures 1 and 3, attached to the first holes (3) and to the second holes (3 ') there are contact pieces (10) destined to remain in contact at all times with the fruit that is found housed in the lower opening (18) and the upper opening (19). The contact pieces (10) have a certain mobility with respect to the first flexible arms (5) and the second flexible arms (2), being able to adapt individually to the contour of the fruit, thus avoiding damaging its delicate skin.
    [0100] The device also comprises at least one bolt (14), attached to the upper annular disk (1), and intended to move along the guide (12) when the upper annular disk (1) rotates with respect to the lower annular disk (4), keeping joined to the lower annular disk (4) and to the upper annular disk (1) and allowing the movement of one with respect to the other.
    [0102] Regarding the operation of the device, as the size of the fruit increases and the contact pieces (10) remain in contact with its surface, without moving with respect to it, the first flexible arms (5) and the second flexible arms (2 ) are getting closer and closer to the upper annular disc (1) and the lower annular disc (4) as appropriate.
    [0104] As schematically illustrated in figure 4, the first flexible arms (5) and the second flexible arms (2) behave in a similar way to a diaphragm, and since the contact pieces (10) cannot be moved with respect to the fruit. , the movement is transferred to the upper annular disc (1) and to the lower annular disc (4), forcing them to rotate on themselves. As the first flexible arms (5) and the second flexible arms (2) are positioned in directions Opposite, each of the annular discs rotates on itself in an opposite direction, one clockwise and the other counterclockwise.
    [0106] In order to quantify this relative displacement of the upper annular disk (1) with respect to the lower annular disk (4), the device comprises elements that are positioned in the interior compartment (11) and that are protected by means of a protection disk ( 6) positioned on the interior compartment (11), designed to protect these elements from external damage, such as those caused by rain or dust.
    [0108] The first of these elements is a coded arc (15), which can be seen in Figure 5, located in the interior compartment (11). In addition, second magnets (16) mounted on a plate (20), associated with the first magnets (13) by a magnetic force, the plate (20) being intended to move through the interior compartment (11), on the coded arc (fifteen).
    [0110] Associated with the plate (20) are reading pins (7), located in correspondence with the coded arc (15) that measure the displacement of the upper annular disk (1) with respect to the lower annular disk (4), following a diagram encoder or encoder type. All the above elements are shown in detail in Figures 8 and 9.
    [0112] In order to transmit this measurement, the device comprises communication means (8), also located in the interior compartment (11). These communication means (8) have a radio frequency antenna, designed to transmit said data to an external device.
    [0114] Finally, in order to power the calibration device, it comprises one or more batteries (9), also in the interior compartment (11). These batteries (9) can be charged externally, to facilitate the task, as well as not to have to break the seal of the interior compartment (11).
