    [0001] AUTOMATIC SYRUP SPRAY DEVICE WITH DETECTION SYSTEM
    [0002]
    [0003]
    [0004]
    [0005] Object of the invention
    [0006] The present invention relates to an automatic syrup spray device with needle position detection system, which allows to know if the device is in closed position or not, so that the control of the manufacturing process of the device is improved. machine where it is equipped, preventing syrup leaks in the aforementioned manufacturing process. The device is applicable in the industry dedicated to food machinery, specifically in the industry dedicated to the production of dragees.
    [0007]
    [0008] Technical problem to solve and background of the invention
    [0009] The manufacture of dragees, is carried out in a drum where the dragees are rotating and at a time of manufacture, by means of spraying devices, a syrup is introduced inside the drum, to provide the dragees with the appearance, texture or flavor exterior that is required according to the type of dragee being manufactured.
    [0010]
    [0011] The usual thing is that the dragee manufacturing machines have a large drum where, by means of several spraying devices, the said syrup is introduced to provide uniformity to the whole quantity of dragees located inside the drum.
    [0012]
    [0013] Likewise, the machines used are automated machines that give the order to open or close the syrup passage inside the drum, so that the opening and closing of the syrup spray devices is automatic.
    [0014]
    [0015] The spraying device has a body, which in turn has a spray nozzle through which the syrup comes out into the drum, and a needle that moves inside the body, so that the needle displacement Open and close the syrup step towards the spray nozzle.
    [0016]
    [0017] During the production process it is also common that when a spray device syrup, should be closed, some type of particle, dirt or other elements (pieces of solid powder that forms the solution of undissolved syrup), remain locked between the tip of the needle and the nozzle, which causes the device Spray does not close properly and there is a drip or unwanted leakage of syrup through the nozzle, when it should be sealed tightly.
    [0018]
    [0019] Since these devices are mounted on automatic dragee manufacturing machines, which do not require the constant presence of the operator, this fact (unwanted or uncontrolled leaks), is not detected, or is too late, with the consequent damage to the process, when syrup falls on product accidentally and unwantedly.
    [0020]
    [0021] In dragee manufacturing machines, several units of these spray devices are normally mounted, depending on the size of the dragee manufacturing machinery.

    [0081]
    [0082] Preferred Embodiment of the Invention
    [0083] As already indicated, and as can be seen in the figures, the object of the invention is an automatic syrup spraying device with a needle closing position detection system (3), which is exposed in a manner detailed throughout this description.
    [0084]
    [0085] The spraying device object of the invention has a valve body (1) comprising an inner housing (2), where a needle (3) is housed, such that the needle (3) has longitudinal movement capacity inside of the interior housing (2).
    [0086]
    [0087] The valve body (1) also comprises a first hole (4) that communicates the outside of the valve body (1) with the inner housing (2) and a second hole (5) that communicates the inner housing (2) with the outside the valve body (1), the first orifice (4) and second orifice (5) being connected to each other through the inner housing (2).
    [0088]
    [0089] At one end of the valve body (1), said valve body (1) comprises a dispersion nozzle (6), this dispersion nozzle (6) is the element through which a syrup is introduced into the interior of the product manufacturing hype.
    [0090]
    [0091] The dispersion nozzle (6) has a tear-shaped machining so that the dosage of the syrup inside the drum is produced in the form of a fan.
    [0092]
    [0093] The first hole (4) is the element through which, in the device object of the invention, the syrup accesses the inner housing (2) and, with the needle (3) in contact with the dispersion nozzle (6), the syrup comes out of the second hole (5) without accessing the inside of the drum.
    [0094] To prevent the syrup from being distributed inside the inner housing (2) instead of flowing into the dispersion nozzle (6) or into the second hole (5) the needle (3) has gaskets (9) located around the same, in contact with the inner wall of the inner housing (2). In other words, the first hole (4), the dispersion nozzle (6) and the second hole (5) form a syrup circulation circuit, since in the machines in which the device object of the invention is installed, the usual it is to place several syrup spray devices in parallel, so that when the syrup does not access the drum through a syrup spray device, it leaves it through a second hole (5) and can access the next syrup spray device to through the first hole (4) of said next syrup spray device, and so on.
    [0095]
    [0096] The inner housing (2) is connected to the outside of the valve body (1) also through a third hole (7) located on one side of the valve body (1) and through a fourth hole (8) located in the end of the valve body (1) opposite the dispersion nozzle (6).
    [0097]
    [0098] Both the third hole (7) and the fourth hole (8) are configured to receive pressurized air. The needle (3) in the area of the inner housing (2) where the third hole (7) and the fourth hole (8) converge has a piston (11) that prevents the third hole (7) and the fourth hole ( 8) communicate with each other, as the needle (3) together with the piston (11) abuts in an inner wall of the inner housing (2) of the valve body (1).
    [0099]
    [0100] The configuration of third hole (7), fourth hole (8) and needle (3) with the piston (11) means that by introducing pressurized air through the third hole (7) the needle moves inside the inner housing (2 ) by opening the syrup passage through the dispersion nozzle (6) and, if pressurized air is introduced through the fourth hole (8), the needle moves inside the inner housing (2) until it contacts the dispersion nozzle ( 6), closing the syrup passage towards said dispersion nozzle (6).
    [0101]
    [0102] There is an intermediate chamber (10) in the valve body (1) that separates the area of the first orifice (4) and second orifice (5), syrup circulation area, from the area of the third orifice (7) and fourth orifice (8) which is the area of circulation of pressurized air. This intermediate chamber (10) also serves to warn if there is any failure in the joints (9) of the first hole (3) and second hole (4), since syrup would appear inside.
    [0103]
    [0104] The needle (3) moves longitudinally in the inner housing (2) with the movement limited to the interior of said interior housing (2). The seals (9) of the device object of the invention have the function of guiding the movement of the needle (3) in the inner housing (2) and causing the needle (3) to move guided inside the inner housing (2) ) without the different holes (4, 5, 7, 8) communicating with each other.
    [0105]
    [0106] In the intermediate chamber (10) of the valve body (1), scraper joints (12) are located, located around the needle (3), whose function is to eliminate any remaining syrup that has been cast into the intermediate chamber (10) from the first hole (4) or second hole (5), since this syrup could end up blocking the movement of the needle (3).
    [0107]
    [0108] Covering the intermediate chamber (10), the device object of the invention has a threaded cover (13) that is easily removable, so that it allows access to the intermediate chamber (10) to detect possible leaks, in case any joint scraper (12) wear.
    [0109]
    [0110] The needle (3) has a tip (14) which is the one that closes or opens the dispersion nozzle (6), making contact with said dispersion nozzle (6), inside the same, as already has been exposed, in the inner housing (2) between the first hole (4) and the second hole (5).
    [0111]
    [0112] Since the tip (14) of the needle (3) is an element subject to wear due to being in contact with the dispersion nozzle (6) and the abrasion to which it is subjected by the syrup particles in contact with the tip ( 14), the tip (14) receives a heat treatment, specifically nitriding at high pressure, to improve its surface hardness.
    [0113]
    [0114] The needle (3) of the device object of the invention has a hole (15) where a first electric cable (16) is connected, said first electric cable (16) is connected to an ohmic resistance converter (17) by the opposite end of the needle connection (3). The ohmic resistance converter (17) transforms the information received from the first electrical cable (16) into an analog signal, such that an automaton (18) processes the analog signal received, generating information on the instantaneous state of the dispersion nozzle ( 6), that is, generating messages of the position of the same closed or open.
    [0115]
    [0116] The ohmic resistance converter (17) is also connected to a second cable electrical (19) that is connected to ground, thus, the ohmic resistance converter (17) is connected to the needle (3) and grounded, and measures the ohmic resistance between the needle (3) (moving part) and the earth (fixed part).
    [0117]
    [0118] When there is no contact between the tip (14) of the needle (3) and the valve body (1), that is to say the dispersion nozzle (6) is introducing syrup inside the drum, the ohmic resistance converter (17 ) gives a certain value, in this case a high value. When the tip (14) of the needle (3) is in contact with the dispersion nozzle (6), that is not between syrup in the drum, the ohmic resistance value is also a determined value, which in this case is a low value, since there is metalmetal contact.
    [0119]
    [0120] There is a third option, which is to be detected with the device object of the invention, and it is one in which the device should be closed, but by some unwanted particle (20) between the dispersion nozzle (6) and the tip (14) of the needle (3), the closure is not complete, in this position the ohmic resistance given by the ohmic resistance converter (17) is different from the two type values (high value and low value) that are established for the open and closed positions, therefore, in this situation the device object of the invention warns that the nozzle can give access to the syrup inside the drum, in an unwanted manner.
    [0121]
    [0122] The piston (11) has the peculiarity that it is non-conductive material, specifically it is Teflon. The material from which the piston (11) is made allows the measurement of the ohmic resistance converter (17) to be made in conditions, that is, if the piston (11) was made of metallic material, the difference in resistance measurement electrical between the open position and the closed position, would be so small that the ohmic resistance converter (17) would not work properly.
    [0123]
    [0124] All the seals (9) of the device object of the invention are made of ethylene propylene diene rubber (EPDM), which offers the following characteristics:
    [0125] - resistance to aging, including weathering or high temperature, ozone and oxidation,
    [0126] - resistance to hot water and water vapor,
    [0127] - resistance to alkalis and even oxidizing acids and in general to all non-hydrocarbon chemical compounds, and
    [0128] - Electrical isolation.
    [0129] What the object of the invention does is to notify if when the needle (3) should be in the closed position, it is not, since if the needle (3) does not close access to the interior of the product manufacturing drum, and the product manufacturing machine is carrying out a drying task of said product that it contains while, due to a failure in the closure, syrup continues to enter, a loss of the manufactured product occurs since the amount of syrup that must be carried during manufacturing does not is fulfilled.
    [0130]
    [0131] The invention should not be limited to the embodiment described herein. Experts in the field can develop other embodiments in view of the description made here. Accordingly, the scope of the invention is defined by the following claims.
