    Protection system for a proximity sensor
    The present invention relates to a protection system for a proximity sensor, which avoids or minimizes the risk of breakage of the proximity sensor in case it is accidentally struck.
    Background of the invention
    It is common to use proximity sensors in manufacturing chains, for example cars, and they are used for the detection of objects or signals that are close to the sensor. Its use favors the automation of a productive process. For safety and economic reasons, these proximity sensors must not have physical contact with the element to be detected. This minimizes the risk that proximity sensors are damaged and, therefore, perform incorrect measurements and / or should be replaced.
    However, reality verifies that a large amount of resources are allocated in proximity sensor replacements due to its deterioration due to contact with the element to be detected.
    The contact with said proximity sensors can be for several reasons, such as, for example, modifications of robot programs, adjustment of tools on tables with rectified coves, or modifications in robot manipulators, among others.
    Protection systems are known in the state of the art that seek to avoid these problems. A protection system of this type adds to a body that houses the proximity sensor of adjustable nuts, which serve as fixing means. The body is housed in a hole of a metal or plastic sheet, pressing the nuts said sheet, thus fixing the body to the sheet. In this way, the position or height of the proximity sensor can be adjusted by positioning the said nuts. However, this protection system does not protect the proximity sensor sufficiently, since if something hits it, it is damaged or broken, even if a correct adjustment of its position has been made.
    Therefore, the objective of the present invention is to provide a protection system

    for proximity sensors that avoid or minimize the risks of the proximity sensor being damaged or broken if it is accidentally struck.
    Description of the invention
    With the protection system of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
    The protection system for a proximity sensor according to the present invention comprises a receptacle body and at least one fixing means, where the receptacle body houses the proximity sensor, a proximity sensor head being disposed substantially at one end of the receptacle body, and where the at least one fixing means is arranged at least partially around the receptacle body, in which the receptacle body is movable with respect to at least one fixing means by the action of at least one elastic means comprised between the receptacle body and the at least one fixing means.
    Thanks to the disposition of the elastic means between the receptacle body and the fixing means, the receptacle body can be displaced in the event of an impact, said elastic means absorbing at least part of the energy, avoiding the breakage of the sensor head . Consequently, the receptacle body and the fixing means do not form a rigid and immobile component, but by means of the action of the elastic means a relative movement between them is allowed, minimizing the damages in case of impact or contact with another external element.
    It should be noted that the at least one fixing means allows an installation of the proximity sensor to a machine, robot or tool, which incorporates the proximity sensor.
    Preferably, in its resting position, the elastic means placed between the receptacle body and the at least one fixing means is expanded, so that it tends to separate the receptacle body from the fixing means. It is noted that the position of rest of the system means that situation in which external forces do not act. That is to say, the spring is at least partially compressed between the elements that stop, but no body or component of the protection system of the present invention has a movement between them.

    Thus, if the receptacle body receives a force from the end where the proximity sensor head is located, the elastic means is compressed, absorbing at least part of the applied effort. Advantageously, the elastic means tends to recover its resting position, so that once the effort applied to the receptacle body has ceased, it recovers its initial position. In this way and in a situation of rest of the system, the sensor is always in the working position, where it has been calculated and parameterized to take the optimal proximity measures for the correct operation of the machine, robot or utensil.
    In addition, if desired, on said receptacle body, stops or position adjustment means can be placed, which can be fixed and / or adjustable, as will be explained below.
    Advantageously, a direction of movement of the receptacle body with respect to the at least one fixing means is substantially coincident with the axis of the receptacle body.
    In this way, the proximity sensor head, located at one end of the receptacle body is protected and allows the proximity sensor head to be brought closer to the fixing means, which is the one that houses the shock-sensitive element, in this direction.
    According to a preferred embodiment, the protection system according to the present invention comprises a first position adjustment means arranged at least partially around the receptacle body, where the at least one elastic means is comprised between the first adjustment means of position and the at least one fixing means.
    According to this embodiment, the system comprises a first means of adjusting the position or movable stop and another fixed.
    In the normal position of use or rest, the first position adjustment means and the fixing means are separated from each other by the action of the elastic means. When the elastic medium is compressed, the first position adjustment means and the fixing means are in contact with each other.
    Advantageously, the first position adjustment means is movable with respect to the receptacle body in a direction of travel substantially coincident with the axis of the
    5

    receptacle body, so that it allows adjustment of an elongation of the at least one elastic means. Thus, by means of the correct positioning of the first position adjustment means, the force of the elastic means is adjusted, as well as the stroke of the receptacle body with respect to the fixing means.
    Preferably, the at least one fixing means comprises a housing for a first end of the at least one elastic means. Thanks to the presence of this housing, at least a part of said elastic means is housed in said housing, performing a guiding function, while retaining the elastic medium.
    According to one embodiment, the protection system according to the present invention may also comprise a second position adjustment means arranged at least partially around the receptacle body, where the second position adjustment means is at one end of the at least one means. of fixation opposite to the first means of position adjustment.
    According to this embodiment, the protection system comprises two movable position adjustment means, the position of which can be adjusted along the receptacle body.
    Advantageously, the second position adjustment means is movable with respect to the receptacle body in a direction of travel substantially coincident with the axis of the receptacle body and because, in a rest position, it is in contact with the at least one fixing means, of so that it allows an adjustment of the position of the at least one fixing means.
    Thus, a movement of the receptacle body with respect to said at least one fixing means is limited by the first position adjustment means and the second position adjustment means. Advantageously, it is not only possible to position the sensor in the optimum measurement position, but with the use of the first and second position adjustment means, it is allowed to regulate the displacement allowed to the sensor in case of impact, the absorption capacity on the part of the elastic medium ...
    It is detailed, therefore, that the protection system of the present invention consists of several embodiments. In a first embodiment, the receptacle body and the fixing means have a relative movement among themselves by the action of an elastic means, which is limited by two fixed stops. Each of said fixed stops is included in the
    5

    receptacle body and in the fixing means. Consequent embodiments show the possibility of replacing at least one of the fixed stops with a first position adjustment means and / or a second fixing means, which are an independent part and can be movable with respect to the receptacle body. In a preferred embodiment, the protection system consists of a first position adjustment means and a second position adjustment means, located at both ends of the fixing means and movable along the receptacle body, maximizing the possibilities of regulation and adaptation of the protection system of the present invention.
    Preferably, the receptacle body is a receptacle body and the external surface of the receptacle body, the internal surface of the first position adjustment means and the internal surface of the second position adjustment means are threaded surfaces.
    In this way, a rotation of the first or second position adjustment means causes its linear displacement on the receptacle body. Also, a rotation of the receptacle body causes a linear displacement on the fixing means, thus facilitating manual regulation by an operator.
    Advantageously, the threaded surfaces comprise the same passage and the same average diameter between them.
    According to a preferred embodiment, the first position adjustment means and the second position adjustment means are nuts, and the at least one elastic means is a helical spring, for example, a conical helical spring. Advantageously, the coil spring guarantees a long and short distance retractable. In addition, the nuts that exert the buttress function provide a quick adjustment of the required working length setting.
    In the event that the helical spring is conical, the end of the conical helical spring with a larger diameter is located in the housing of the at least one fixing means.
    Preferably, the proximity sensor is an inductive proximity sensor, which generates a magnetic field and detects the losses of current of said field generated when introduced into the ferrous and non-ferrous detection objects. This type of proximity sensor is especially good for metal plate detection.

    Figure 2 is a sectional side view of the protection system for a proximity sensor according to the present invention.
    Description of a preferred embodiment
    The protection system according to the embodiment represented in the figures comprises a fixing means 1, which in combination with a nut 5 allows the protection system to be fixed, for example, to a sheet of metal or plastic, not represented in the figures.
    The protection system according to the embodiment shown also comprises a receptacle body 3 that houses a proximity sensor 6 provided with a head, this head being located at one end of said receptacle body 3.
    Preferably, the proximity sensor 6 is an inductive proximity sensor, which generates a magnetic field and detects the losses of current of said field generated when introduced into the ferrous and non-ferrous detection objects.
    As can be seen in the figures, said fixing means 1 is arranged around said receptacle body 3 and is longitudinally movable with respect to it by the action of an elastic means 2.

    Said elastic means 2 is preferably a helical spring, for example conical, which at one of its ends 21 is housed in a housing 11 of said fixing means 1, and at its other end 22 contacts a first position adjustment means 41 .
    This first position adjustment means 41, according to a preferred embodiment, is movable along said receptacle body 3, although it could be fixed and form part of the receptacle body itself 3. For example, said first position adjustment means , according to the embodiment shown, is a nut that acts as a stop for said end of the elastic means 2.
    The movement of the first position adjustment means 41 can be carried out in any suitable manner, for example, by means of a thread of said complementary nut with a thread of the external surface of the receptacle body 3.
    In accordance with the embodiment shown, the protection system also comprises a second position adjustment means 42, which can also be movable or fixed. This second position adjustment means 42 is in contact with one of the ends of said fixing means 1, in particular the end that is not in contact with the elastic means 2.
    The characteristics and configuration of this second position adjustment means 42 are substantially the same as those of the first position adjustment means 41, which are not repeated again for simplicity.
    In the normal position of use or rest of the protection system, shown in the figures, the first position adjustment means 41 and the fixing means 1 are separated from one another by the action of the elastic means 2. When the elastic means 2 it is compressed, the first position adjustment means 41 and the fixing means 1 approach and can become in contact with each other. The compression of the elastic means 2 is carried out in the event that the proximity sensor 6 contacts an external element that it is desired to detect, avoiding or minimizing the risk that the head of said proximity sensor 6 is broken, allowing its displacement.
    When the proximity sensor 6 stops contacting said external element, the elastic means 2 causes the protection system to automatically return to its original resting position.
    Said resting position is limited by the position of the second position adjusting means 42 in relation to the receptacle body 3. It will be the stop that marks the resting position of the system, that is, that position in which the components that make up the Protection system of the present invention are not affected by any external force.
    Although reference has been made to a specific embodiment of the invention, it is evident to one skilled in the art that the described protection system is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others. technically equivalent, without departing from the scope of protection defined by the appended claims.
