Definitions
- the present invention relates to devices for marking highway, road, airport, port or other areas, using plastic cones known per se.
- Beaconing is currently done by colored plastic cones (orange-red, and reflective strips). They are standardized country by country but have substantially the same characteristics (same dimensions, same types of weight, etc.). They are rigid and weigh about 4.5 kg for a height of 75 cm (for models used in France), with a sole at the foot of the cone, larger than the diameter of the cone at its base, all (rigidity , weight, sole) to ensure good wind resistance. Being plastic, they offer a slight elasticity due to this type of material, but they are not flexible.
- the pose is a relatively tiring operation for the operators, but it still requires to lean out of the vehicle, to deposit at regular intervals on the markings on the ground with a good alignment. This pose is done at slow speed, 7 or 8 km / h approximately.
- the installation is done in front, pickup in reverse: it must always be protected by markup.
- the device according to the invention also operates in the FRONT mode, fitting appropriately and obviously mounting the complete system (including the device according to the invention) on the side or the front of the vehicle.
- AR or rear will designate the rear of the vehicle or a displacement towards the rear of the vehicle; AV or before, the opposite.
- the Applicant has therefore turned to the creation of a device for placing and picking cones safely and facilitating the work of the operator, and making the laying and picking operations significantly faster.
- the main problem is to increase the speed of pickup. All without excluding a pickup at the current low speed, that is to say a device fully compatible with current equipment, personal and work habits.
- the present invention specifically relates to a dynamic percussion device for cone collecting devices.
- the present invention is based on a completely autonomous continuous system for the operation of setting and collecting cones, and not sequentially as most devices of the prior art.
- the present invention therefore relates to a dynamic percussion device adapted to be fixed on standardized cone collecting devices including a roller conveyor or belt disposed in known manner at the rear or along a side wall of the pickup vehicle , and ending at a door side where the operator is.
- This device is fixed, adapt, on the side walls of a cone conveyor.
- it could also be adapted to the rear of the vehicle, or even operate forward, depending on local work habits, the vehicle available, the location of the operation, for example if the approach of the vehicle requires a step forward (as for a mobile shipyard with a buoyage vehicle at the head and deballing at the rear, or airport, port area, any area with fragile materials, etc ... or simply for better visibility of the driver).
- the invention proposes a device for rapid collection and possibly the laying of markers as defined by claim 1.
- the invention also provides a method of collecting markup cones defined by claim 18 using the device of claim 1.
- the invention further provides a method of laying marker cones defined by claim 19 using the device of claim 1 with the striker removed or placed in the up position.
- the invention is based on a device for the quick pick-up and possibly the installation of markers, intended to be positioned on one side, or the rear, or the front of a pick-up vehicle, said device comprising a "medium percussion technique ", for slightly tilting a cone to be gripped and transported, secured to the pickup device, whose collecting vehicle is secured, which creates the movement of the striker and thus the" percussion "against the cone, characterized in that the "technical means of percussion” includes a rear MOBILE cone striker rear AR forward AV and front AV rear AR - AR and AV designating the usual but not limiting direction of the pickup vehicle - said mobility being essentially obtained by a "technical means of guidance" of the striker AR to AV then AV to AR, and the impulse or kinetic energy generated by the percussion of the mobile striker on the cone, said "percussion technique means” being adapted to strike the cone when the pick-up vehicle is running and to be “violently / rapidly” fired forward AV
- these terms define a violent percussion (due to a high speed of the collection vehicle, which is one of the essential objectives of the invention) which therefore generates a pulse / kinetic energy a small part of which serves to tilting the cone without tilting it, the vast majority of said energy being transmitted to the striker (since, being much lighter than the cone, it "resists” less than the cone at said energy) which, being MOBILE from AR to AV (and AV to AR), is “violently” and therefore “quickly” returned to the AV of the vehicle, where a means of damping (not to damage or fatigue the equipment) and especially of return, receiving, absorbs some of its energy and restores so-called “residual” energy to said striker to send it "violently” and thus “quickly” to the AR.
- the hydraulic damper is arranged in such a way that the firing pin also has a natural tendency to fall on the stable side, that is to say downwards, in percussion position. This is useful for low speed percussion where kinetic energy is lower.
- the "guide means" may be arbitrary: in what follows, and on the prototype made, the arm carrying the striker is rotatable about an axis perpendicular to the direction of travel; arranged below the level of percussion for the prototype, one can however consider technical equivalents where the striker (which is generally a horizontal bar also perpendicular to the direction of the march) is articulated above the height of percussion, or is guided by two rails each forming a horizontal U-shaped groove where said striker circulates, with ball bearings to reduce friction.
- said damping / return means may itself give energy to the firing pin, for an even faster return to its initial position: for example, this may be the case of a spring means, which at the same time damps and restores energy to the firing pin, or a jack, or even an active means that stores energy before the firing pin reaches it, and restores it when shock: in particular a spring or cylinder, or a flexible metal blade, "alleged" by a motor (for example auger) or by a slave cylinder, this "pre-tension” forming an energy that is restored when the striker strikes said deflection means (the trigger being by a simple means such as an electrical contact, the tilting of a finger struck by the striker, etc ).
- the essential characteristic is the dynamic return device, because it fulfills two essential functions: 1 / very quickly retract the striker while dosing the tipping energy communicated to the cone, and 2 / return very quickly, by a movement forced, after the passage of the cone, the percussion means to its initial position where it can very quickly hit a new cone.
- This fast dynamic return allows a very high rate of collection, for example 15 to 20 km / h, and even 30 km / h depending on the temperature conditions.
- Said damping / dynamic return device may be passive, for example a spring or a jack that the return to the AV compresses and which expands to return the percussion means to the AR, or active, it is up to for example, a motorized actuator which is armed during the return phase to the firing pin's AR, and which strikes the striker by giving it a strong impulse towards the AR when the firing striker strikes it at the end of its stroke towards the AV .
- the figure 13 represents a view of the AR of a schematic and nonlimiting example of the device according to the invention, ie the conveyor (arrow), its chassis CH, the support 11 secured to the frame, the pivot 7 the arm 3 and the percussion rod 6 integral with the arm 3.
- the percussion means 6 (seen from the side) is in the percussion position. It is seen that it will strike the cone at point A distance d) being easily computable by the skilled person by means of elementary rules of geometry, kinematics, and at most with some routine tests.
- This point A is chosen so that it allows the percussion rod 6 not to be blocked by the cone but on the contrary to be lifted by the conical wall and to pass over the horizontal level of the tip of the cone. The vehicle moves back with an ALPHA speed.
- the cone is on the conveyor, and the arm (3) strikes the damping / return means (8) (schematized here by a piston with a return spring).
- the invention lies essentially in the fact that the energy E is transformed in a very large part, via the return means (8), into a violent force of return RC
- this RC force has resulted in the return of the arm (3) and striker (6) with a high speed v to the initial position where a new cone can be struck.
- the means (8) can be adjustable and be calibrated in particular according to the speed chosen. It will be obvious to those skilled in the art that the higher the desired collection speed is chosen, the more powerful the return means (8) will be (for example, it will be possible to pre-compress the spring, or to calibrate the jack if this is a jack).
- This may be for example another hydraulic damper, a conical rubber stop, disposed at a suitable distance from the axis of rotation according to its stiffness.
- the percussion device (1) of the present invention comprises a dynamic percussion means (3) designed to strike a cone (2) in order to tilt it slightly (it is necessary to raise the sole enough to engage on the conveyor, about 8 to 12 cm) so that the cone can be transported by a conveyor (4).
- dynamic percussion means is meant that this means is movably fixed around an attachment point (7) located in the upper part of the side walls (11) of said conveyor (4) (unlike the prior art where this means of percussion is systematically not mobile).
- Said striking means (3) consists of at least one articulated arm (5) pivotally mounted about an axis of rotation perpendicular to the conveyor, at said attachment point (7), and which comprises a percussion bar-type element (6) at its upper end (parallel to the conveyor), the percussion means forming a substantially arch form.
- Said percussion means (3) is geometrically adapted such that, in retreating, the percussion bar (6) strikes the upper part of the cone at a point (A) remote from the vertex (S) of the cone of a distance (d).
- This distance d is adapted so that when the percussion bar (6) tilts the cone by action / percussion on the point (A), the cone tilts up enough to lift his sole so that it can fall on the conveyor (4).
- the cone (2) and the point (A) are geometrically adapted to push said articulated arm around its point of attachment (7) by strongly forcing it forward (AV) where the articulated arm (5) strikes a first means damping and deflection means (8), which by reaction with the energy transmitted by the articulated arm (5), rapidly returns said arm (and thus the percussion bar) to its initial percussion position, while the cone, which has escaped from the percussion bar, gravitates forward (AV) under said percussion bar and lands with its sole on the conveyor.
- Said first damping and return means (8) is located on the rear face of said side wall (11).
- Said damping and return means is advantageously designed to absorb a large part of the energy transmitted by the percussion means after percussion of the cone.
- Said percussion means may also advantageously consist of at least a second damping means (9), and only damping, located on the front face of said side wall (11), facing said first damping means and return (8), which comes to rest, in the rest position, said percussion means (that is to say before percussion of a cone).
- the cone will be struck by said percussion means (3).
- the cone will use some of the energy for its own tilting and lifting of its sole (10), and will transmit some energy (created by the impact, the speed of the vehicle, etc., basic physical concepts) by means of percussion which, being mobile , will retract or, in a preferred embodiment projecting forwardly in rotation around its attachment point (7) to meet said first damper and return means (8).
- Said first damper and return means (8) will then absorb a portion of the energy, then will restore a portion by means of percussion (3) to return it to its initial rest position which is located on said second damping means (9). The latter will then fully absorb the remaining energy transmitted by the percussion means, so that the latter remains in a static position. Once this static rest position is reached, the device is again operational to strike a new cone.
- the heart of the invention is a moving means of rotation in rotation, with "dissipation and use” of the kinetic energy created by the impact with the cone.
- the device by the interaction of the first damping and deflection means (8), the second damping means (9), and the mobile percussion means (3), allows a very large dissipation of the overflow of energy that could cause multiple bouncing of the percussion means and thus impede the proper functioning of the entire device, while using the residual energy to return said percussion means to its initial position, the damping and the return " dynamic "making it possible to accelerate the rate of collection of cone , without risk of dropping the cone.
- the higher the speed of the vehicle the stronger the retraction pulse of the percussion means (3) and thus the latter retracts faster, preventing the cone from taking a dangerous inclination .
- the speed of the vehicle within reasonable limits, that is to say from 1 to about 30 km / h
- the speed at which the percussion means will come crashing into the cone it will be substantially the same shock between the percussion means and the cone, creating substantially the same energy transfer.
- the articulated arm may be fixed in said position by any known means to the side wall (straps, pins, stops etc.).
- the user will put the cones at regular intervals on the conveyor that has been previously put in the reverse operating position with respect to the operation of collecting cones, that is to say to transport the cone to the road.
- Said percussion device (1) being attached to two side walls (11), themselves connected to the cone conveyor (4).
- Said striking means (3) rests on said second damping means (9), and is in position to strike a cone (2) to tilt it.
- the first damping and deflection means (8) is preferably of hydraulic damping type or any other means capable of absorbing a certain amount of energy and also of restoring a certain amount of energy. part, such as for example a spring / damper couple, etc.
- said second damping means (9) is preferably a rubber stop element sufficiently soft to absorb the kinetic energy that will be transferred to it by the percussion means (3), so as to to avoid any further transfer.
- Said articulated arm (5) is movably fixed around an attachment point (7) allowing rotation around this point of the percussion means (3), after percussion of the cone (2).
- the percussion device (1) comprises two hydraulic dampers and two rubber-like elements arranged on each of the side walls (11) of the conveyor.
- the distance d is between 4 and 6 cm
- the bar (6) and the arm (5) are made of aluminum or stainless steel material and have a diameter of 3 cm.
- Operating modes 1 and 2 are mainly used with the device of the present invention.
- the devices of the prior art systematically tilt the cone completely; this has created in this industry a prejudice against the search for "quick" pickups.
- the geometry will be adapted accordingly, the mass of the striker will be reduced by 30%.
- the mass and the inertia of the striker will be proportionally modified: it is the mass of the cone, its mass distribution, its rigidity which determines, by law of proportionality, the mass of the striker, its mass distribution and the damping values.
- the skilled person will be able to adapt the dimensions of the components so as to maintain an energy distribution identical to that defined above between cone and retraction of the striker.
- the retraction movement of the firing pin can be directed upwards by a rotational movement, upwardly biased by a translation movement, laterally on the side, by a rotational or translational movement, or by deformation of an elastic connection having characteristics close to the means 8 damping / return.
- the striker can also be constituted as indicated in figure 15 of a double pivoting bar with a circular motion by half turn: the percussion of a first cone rotates the double reciprocating firing assembly on a half turn while the cone passes below, the second bar of the firing pin then arrives in percussion position and the assembly is stopped in position by a damping means, the percussion of a second cone producing on the second bar the same effect as on the first, and so on.
- the skilled person will decline this principle with 3 bars or more, or imagine other systems using a controlled energy distribution between cone and striker.
- the invention also covers all the embodiments and all the applications which will be directly accessible to the person skilled in the art upon reading the present application, and of his own knowledge.

Description
La présente invention se rapporte à des dispositifs permettant les balisages autoroutiers, routiers, d'aéroports, de zones portuaires ou autres, en utilisant des cônes plastiques connus en soi.The present invention relates to devices for marking highway, road, airport, port or other areas, using plastic cones known per se.
Le balisage est réalisé actuellement par des cônes en plastique de couleurs (rouge orangée, et bandes réfléchissantes). Ils sont normalisés pays par pays mais possèdent sensiblement les mêmes caractéristiques (mêmes dimensions, mêmes types de poids, etc.). Ils sont rigides et pèsent environ 4,5 kg pour une hauteur de 75 cm (pour les modèles employés en France), avec une semelle au pied du cône, de dimension plus large que le diamètre du cône à sa base, le tout (rigidité, poids, semelle) pour assurer une bonne résistance au vent. Etant en matière plastique, ils offrent une légère élasticité due à ce type de matériau, mais ils ne sont pas flexibles.Beaconing is currently done by colored plastic cones (orange-red, and reflective strips). They are standardized country by country but have substantially the same characteristics (same dimensions, same types of weight, etc.). They are rigid and weigh about 4.5 kg for a height of 75 cm (for models used in France), with a sole at the foot of the cone, larger than the diameter of the cone at its base, all (rigidity , weight, sole) to ensure good wind resistance. Being plastic, they offer a slight elasticity due to this type of material, but they are not flexible.
Jusqu'à présent, ces cônes en matière plastique sont principalement posés et ramassés manuellement par un ou plusieurs opérateurs à partir d'un véhicule (principalement un véhicule dit « utilitaire » équipé de portes latérales). Un balisage classique représente souvent 100 à 300 cônes.Until now, these plastic cones are mainly laid and manually picked up by one or more operators from a vehicle (mainly a "utility" vehicle equipped with side doors). Classic markup often represents 100 to 300 cones.
La pose est une opération relativement peu fatigante pour les opérateurs, mais elle exige tout de même de se pencher en dehors du véhicule, de déposer à intervalle régulier sur les marquages au sol avec un bon alignement. Cette pose se fait à vitesse lente, 7 ou 8 km/h environ.The pose is a relatively tiring operation for the operators, but it still requires to lean out of the vehicle, to deposit at regular intervals on the markings on the ground with a good alignment. This pose is done at slow speed, 7 or 8 km / h approximately.
La récupération des cônes est en revanche beaucoup plus pénible. En effet, il faut que l'opérateur se penche hors du véhicule, attrape « au vol » le cône (sans que celui-ci ne glisse des mains) et l'empile dans la zone de stockage prévue dans le véhicule. Avec la vitesse du véhicule, le poids apparent du cône peut être multiplié par deux ou trois pendant la prise à cause de l'accélération. Cet effort, réalisé à environ 25 cm du plancher du véhicule - le plancher du véhicule étant à environ 50 cm du sol - oblige l'utilisateur à se pencher tout en réalisant un effort en torsion. Cela est pénible et fatigant à la longue. A cela s'ajoute la nécessité de sortir la tête et une partie du corps du camion, proche de la zone de passage des autres véhicules automobiles, ce qui s'avère naturellement dangereux sur autoroutes où les véhicules peuvent rouler à grande allure.Recovery of cones is much more difficult. Indeed, it is necessary that the operator looks out of the vehicle, catches "on the fly" the cone (without it slipping hands) and stacks in the storage area provided in the vehicle. With vehicle speed, the apparent weight of the cone can be multiplied by two or three during setting because of acceleration. This effort, made about 25 cm from the floor of the vehicle - the floor of the vehicle being about 50 cm from the ground - requires the user to bend while achieving a torsional force. This is painful and tiring in the long run. Added to this is the need to remove the head and a part of the body of the truck, close to the passage area of other motor vehicles, which is naturally dangerous on highways where vehicles can drive at great speed.
Pour des raisons de sécurité, la pose se fait en marche avant, le ramassage en marche arrière : il faut toujours être protégé par le balisage. Cependant, le dispositif selon l'invention fonctionne également en marche AVANT, en adaptant de manière appropriée et évidente le montage du système complet (incluant le dispositif selon l'invention) sur le côté ou à l'avant du véhicule. Ces équivalents techniques font partie de l'invention, ainsi que tous autres équivalents techniques.For reasons of safety, the installation is done in front, pickup in reverse: it must always be protected by markup. However, the device according to the invention also operates in the FRONT mode, fitting appropriately and obviously mounting the complete system (including the device according to the invention) on the side or the front of the vehicle. These technical equivalents form part of the invention, as well as any other technical equivalents.
Dans ce qui suit, AR ou arrière désignera l'arrière du véhicule ou un déplacement vers l'arrière du véhicule ; AV ou avant, l'inverse.In the following, AR or rear will designate the rear of the vehicle or a displacement towards the rear of the vehicle; AV or before, the opposite.
L'acuité du problème et le nombre de véhicules de ramassage ont suscité plusieurs inventions dans ce domaine, toutes basées sur des principes différents, mais présentant toutes des inconvénients.The acuity of the problem and the number of collection vehicles have given rise to several inventions in this field, all based on different principles, but all with disadvantages.
Tous les documents et dispositifs connus ont en commun un dispositif venant percuter le cône en partie haute afin de le faire soit légèrement basculer vers l'AR pour qu'il puisse être suffisamment incliné pour être saisi puis transporté (au niveau de la semelle) par un convoyeur, qui va ensuite amener le cône à la hauteur du véhicule (généralement au niveau de sa porte latérale, mais également sur sa face arrière), soit le faire basculer complètement pour qu'il puisse être saisi par un système annexe.All known documents and devices have in common a device that strikes the cone at the top to make it tilt slightly towards the AR so that it can be inclined enough to be grasped and then transported (at the sole) by a conveyor, which will then bring the cone to the height of the vehicle (usually at its side door, but also on its rear face), or toggle it completely so that it can be grasped by a side system.
On connaît notamment le brevet
Le principal inconvénient de ce brevet (ainsi que de tous les brevets présentant un percuteur fixe) est que la percussion risque de faire totalement basculer le cône, et ceci d'autant plus si le véhicule dépasse une certaine vitesse limite ; vitesse limite qui malheureusement se situe bien souvent en dessous de la vitesse limite de fonctionnement du mode manuel.
On connaît le document
De plus, la plupart des dispositifs ne fonctionnent que si le véhicule roule à très faible allure, expliquant de fait qu'ils ne soient pas utilisés, car l'utilisateur préférera utiliser le mode manuel, notamment par gain de temps (même si celui ci présente des inconvénients très sérieux comme indiqués ci-dessus).
Il existe de nombreux autres documents traitant de ce sujet, mais dont les dispositifs sont de nature extrêmement complexe, soit qui nécessitent l'utilisation de cônes spécialement étudiés et réalisés pour fonctionner avec lesdits dispositifs.
Le fait est que de nos jours, sur les routes nous croisons rarement des véhicules équipés de ce genre de dispositifs de ramassage ; ce qui prouve que l'homme du métier privilégie encore très nettement le mode manuel car, malgré les inconvénients listés ci-dessus, il présente moins d'inconvénients que les dispositifs brevetés. En quelque sorte on peut dire que l'homme du métier privilégie la solution la moins mauvaise.We know in particular the
The main disadvantage of this patent (as well as all the patents with a fixed firing pin) is that the percussion may cause the cone to tilt completely, all the more so if the vehicle exceeds a certain limit speed; speed limit which unfortunately is often below the limit speed of operation of the manual mode.
We know the document
In addition, most devices only work if the vehicle is running at a very low speed, explaining that they are not used, because the user will prefer to use the manual mode, especially by saving time (even if this one has very serious disadvantages as indicated above).
There are many other documents dealing with this subject, but whose devices are extremely complex in nature, or that require the use of specially designed cones and made to work with said devices.
The fact is that nowadays, on the roads, we rarely see vehicles equipped with this type of pickup device; which proves that the person skilled in the art still very much favors the manual mode because, despite the disadvantages listed above, it has fewer disadvantages than the devices Patented. In a way, we can say that the person skilled in the art favors the least bad solution.
Cette industrie a considéré comme illusoire les solutions au problème posé, et a abandonné semble-t-il toute recherche innovante en ce domaine.This industry has considered illusory solutions to the problem, and apparently abandoned any innovative research in this area.
Il existe donc, malgré ce fort préjugé, un réel besoin de sécuriser cette opération de balisage tout en la rendant moins pénible et moins dangereuse pour l'opérateur, et surtout plus rapide. Vu le grand nombre de cônes déjà en utilisation, le Demandeur ne pouvait pas se permettre de modifier les caractéristiques des cônes ; et ceci d'autant plus que les cônes sont souvent normalisés.There is therefore, despite this strong prejudice, a real need to secure this tagging operation while making it less painful and less dangerous for the operator, and especially faster. Considering the large number of cones already in use, the Applicant could not afford to modify the characteristics of the cones; and this especially as the cones are often standardized.
L'un des mérites du Demandeur est d'avoir malgré tout recherché une solution efficace et élégante.One of the merits of the Claimant is to have nevertheless sought an effective and elegant solution.
Le Demandeur s'est donc tourné vers la création d'un dispositif permettant de poser et ramasser les cônes en toute sécurité et en facilitant le travail de l'opérateur, et en rendant les opérations de pose et de ramassage nettement plus rapides. Le problème principal posé est d'augmenter la rapidité du ramassage. Le tout sans exclure un ramassage à la faible vitesse actuelle, c'est-à-dire un dispositif totalement compatible avec les matériels, personnels et habitudes de travail actuels.The Applicant has therefore turned to the creation of a device for placing and picking cones safely and facilitating the work of the operator, and making the laying and picking operations significantly faster. The main problem is to increase the speed of pickup. All without excluding a pickup at the current low speed, that is to say a device fully compatible with current equipment, personal and work habits.
La présente invention concerne spécifiquement un dispositif de percussion dynamique pour dispositifs de ramassages de cônes.The present invention specifically relates to a dynamic percussion device for cone collecting devices.
La présente invention est basée sur un système en continu totalement autonome pour l'opération de pose et de ramassage des cônes, et non en séquentiel comme la plupart des dispositifs de l'art antérieur.The present invention is based on a completely autonomous continuous system for the operation of setting and collecting cones, and not sequentially as most devices of the prior art.
La présente invention concerne donc un dispositif de percussion dynamique adapté pour se fixer sur des dispositifs de ramassage de cônes standardisés notamment un convoyeur à rouleaux ou à bande disposé de manière connue à l'arrière ou le long d'une paroi latérale du véhicule de ramassage, et se terminant au niveau d'une porte latérale où se trouve l'opérateur. Ce dispositif vient se fixer, s'adapter, sur des parois latérales d'un convoyeur de cône.
On a vu qu'il pouvait aussi être adapté à l'arrière du véhicule, ou même fonctionner en marche avant, selon les habitudes locales de travail, le véhicule disponible, le lieu de l'opération, par exemple si l'approche du véhicule requiert une marche en avant (comme pour un chantier mobile avec un véhicule de balisage en tête et de débalisage à l'arrière, ou sur aéroport, zone portuaire, toute zone comportant des matériels fragiles, etc... ou simplement pour une meilleure visibilité du conducteur). Il s'agit d'équivalents techniques évidents qui font partie de l'invention sans qu'il soit besoin, ni de les décrire en détail, ni de les revendiquer spécifiquement.
A cet effet, l'invention propose un dispositif pour le ramassage rapide et éventuellement la pose de cônes de balisage tel que définit par la revendication 1.
L'invention propose aussi un procédé de ramassage de cônes de balisage définit par la revendication 18 en utilisant le dispositif de la revendication 1.
L'invention propose en plus un procédé de pose de cônes de balisage définit par la revendication 19 en utilisant le dispositif de la revendication 1 dont le percuteur est retiré ou placé en position haute.The present invention therefore relates to a dynamic percussion device adapted to be fixed on standardized cone collecting devices including a roller conveyor or belt disposed in known manner at the rear or along a side wall of the pickup vehicle , and ending at a door side where the operator is. This device is fixed, adapt, on the side walls of a cone conveyor.
We have seen that it could also be adapted to the rear of the vehicle, or even operate forward, depending on local work habits, the vehicle available, the location of the operation, for example if the approach of the vehicle requires a step forward (as for a mobile shipyard with a buoyage vehicle at the head and deballing at the rear, or airport, port area, any area with fragile materials, etc ... or simply for better visibility of the driver). These are obvious technical equivalents that are part of the invention without the need to either describe them in detail or claim them specifically.
For this purpose, the invention proposes a device for rapid collection and possibly the laying of markers as defined by
The invention also provides a method of collecting markup cones defined by claim 18 using the device of
The invention further provides a method of laying marker cones defined by claim 19 using the device of
L'invention repose sur un dispositif pour le ramassage rapide et éventuellement la pose de cônes de balisage, destiné à être positionné sur un côté, ou l'arrière, ou l'avant d'un véhicule de ramassage, ledit dispositif comportant un « moyen technique de percussion », pour basculer légèrement un cône afin d'être saisi puis transporté, solidaire du dispositif de ramassage, dont le véhicule de ramassage est solidaire, ce qui crée le mouvement du percuteur et donc la « percussion » contre le cône, caractérisé en ce le « moyen technique de percussion » comporte un percuteur de cône MOBILE d'arrière AR en avant AV et d'avant AV en arrière AR - AR et AV désignant le sens habituel mais non limitatif de marche du véhicule ramasseur - ladite mobilité étant essentiellement obtenue par un « moyen technique de guidage » du percuteur AR vers AV puis AV vers AR, et par l'impulsion ou énergie cinétique générées par la percussion du percuteur mobile sur le cône, ledit « moyen technique de percussion » étant adapté pour percuter le cône lorsque le véhicule de ramassage est en marche et pour être renvoyé « violemment/rapidement » vers l'avant AV par l'impulsion ou l'énergie cinétique générées par la percussion, vers un moyen d'amortissement/ renvoi, puis de revenir « violemment/rapidement », grâce à l'énergie cinétique résiduelle restituée par ledit moyen d'amortissement/renvoi, vers sa position de départ pour la percussion d'un nouveau cône, le tout en succession rapide par dissipation de l'énergie cinétique.The invention is based on a device for the quick pick-up and possibly the installation of markers, intended to be positioned on one side, or the rear, or the front of a pick-up vehicle, said device comprising a "medium percussion technique ", for slightly tilting a cone to be gripped and transported, secured to the pickup device, whose collecting vehicle is secured, which creates the movement of the striker and thus the" percussion "against the cone, characterized in that the "technical means of percussion" includes a rear MOBILE cone striker rear AR forward AV and front AV rear AR - AR and AV designating the usual but not limiting direction of the pickup vehicle - said mobility being essentially obtained by a "technical means of guidance" of the striker AR to AV then AV to AR, and the impulse or kinetic energy generated by the percussion of the mobile striker on the cone, said "percussion technique means" being adapted to strike the cone when the pick-up vehicle is running and to be "violently / rapidly" fired forward AV by the impulse or kinetic energy generated by the percussion, to damping / return means, then return "violently / quickly", thanks to the residual kinetic energy restored by said damping / return means, to its starting position for the percussion of a new cone, the whole in rapid succession by dissipation of kinetic energy.
On comprendra qu'il est impossible de définir des termes tels que «violemment» ou «rapidement» car ils sont fonction du véhicule, de sa vitesse, du poids du cône, des habitudes locales de travail etc...It will be understood that it is impossible to define terms such as "violently" or "quickly" because they are a function of the vehicle, its speed, the weight of the cone, local working habits, etc.
Selon l'invention, ces termes définissent une percussion violente (due à une vitesse élevée du véhicule de ramassage, ce qui est l'un des objectifs essentiels de l'invention) qui engendre donc une impulsion/énergie cinétique dont une faible partie sert à incliner le cône sans le faire basculer, la grande majorité de ladite énergie étant transmise au percuteur (car, étant beaucoup plus léger que le cône, il « résiste » moins que le cône à ladite énergie) qui, étant MOBILE d'AR en AV (et d'AV en AR), est « violemment » et donc « rapidement » renvoyé vers l'AV du véhicule, où un moyen d'amortissement (pour ne pas endommager ou fatiguer le matériel) et surtout de renvoi , le réceptionne , absorbe une partie de son énergie et restitue de l'énergie dite « résiduelle » au dit percuteur pour le renvoyer « violemment » et donc « rapidement » vers l'AR.According to the invention, these terms define a violent percussion (due to a high speed of the collection vehicle, which is one of the essential objectives of the invention) which therefore generates a pulse / kinetic energy a small part of which serves to tilting the cone without tilting it, the vast majority of said energy being transmitted to the striker (since, being much lighter than the cone, it "resists" less than the cone at said energy) which, being MOBILE from AR to AV (and AV to AR), is "violently" and therefore "quickly" returned to the AV of the vehicle, where a means of damping (not to damage or fatigue the equipment) and especially of return, receiving, absorbs some of its energy and restores so-called "residual" energy to said striker to send it "violently" and thus "quickly" to the AR.
Pour prendre un exemple non limitatif,
- pour un cône de 4,5 kg,
- un moyen de percussion comportant un bras mobile (3) de longueur 50 cm et une barre transversale de percussion de
diamètre 3 cm, de poids total 800 g - un véhicule reculant ou avançant entre 15 et 20 km/h
- la percussion d'une barre de percussion sur le haut du cône renvoie ladite barre en 1 seconde (temps estimé et fortement variable selon la vitesse véhicule et de nombreux paramètres) vers un moyen d'amortissement/renvoi, notamment, sur le prototype, un amortisseur hydraulique de type vérin,
- lequel est comprimé par l'arrivée du percuteur, absorbe une partie de l'énergie correspondante, et en restitue l'énergie « résiduelle » (moins les frottements et autres effets parasites connus) au dit percuteur
- lequel revient en 1 s (temps estimé et fortement variable selon la vitesse véhicule et de nombreux paramètres) à sa position de départ AR, prêt pour la percussion d'un nouveau cône.
- LE CYCLE EST DONC D'ENVIRON 1s + 1s SOIT ENVIRON 2s.
- for a 4.5 kg cone,
- a percussion means comprising a movable arm (3) of length 50 cm and a percussion transverse bar of
diameter 3 cm, total weight 800 g - a vehicle receding or advancing between 15 and 20 km / h
- the percussion of a percussion bar on the top of the cone returns said bar in 1 second (estimated time and highly variable depending on the vehicle speed and many parameters) to a means of damping / return, in particular, on the prototype, a hydraulic damper type cylinder,
- which is compressed by the arrival of the firing pin, absorbs a portion of the corresponding energy, and restores the "residual" energy (minus friction and other known parasitic effects) to said firing pin
- which returns in 1 s (time estimated and highly variable depending on the vehicle speed and many parameters) to its starting position AR, ready for the percussion of a new cone.
- THE CYCLE IS SO ABOUT 1s + 1s ABOUT 2s.
Enfin, l'amortisseur hydraulique est disposé de manière telle que le percuteur ait aussi naturellement tendance à retomber du coté stable, c'est-à-dire vers le bas, en position de percussion. Ceci est utile pour les percussions à faible vitesse où l'énergie cinétique est plus faible.Finally, the hydraulic damper is arranged in such a way that the firing pin also has a natural tendency to fall on the stable side, that is to say downwards, in percussion position. This is useful for low speed percussion where kinetic energy is lower.
L'homme de métier aura cependant compris que :
- la percussion génère une impulsion / énergie cinétique qui est fonction de la vitesse de percussion, laquelle est fonction de la vitesse de roulement du véhicule de ramassage ;
- cette impulsion/énergie cinétique escamote le percuteur loin du cône, et dans le prototype et l'objet de l'invention, renvoie le percuteur en avant car il est MOBILE ; à vitesse élevée, ce renvoi est « violent » et donc « rapide » ;
- le percuteur ainsi escamoté ou renvoyé est stoppé par un moyen d'amortissement et de renvoi, qui peut être quelconque, lequel amortit le choc et surtout renvoie le percuteur vers sa position initiale grâce à l'énergie cinétique « résiduelle » et/ou à la gravité (si l'escamotage a lieu vers le haut).
- l'homme de métier a déjà compris que pour qu'il existe une énergie cinétique « résiduelle », il convient que l'énergie cinétique créée par la percussion soit supérieure à l'énergie suffisante pour renvoyer le percuteur vers le moyen d'amortissement/renvoi ; dans le cas contraire, il n'y aurait pas de « renvoi » ; l' homme de métier a aussi compris que ladite énergie résiduelle doit être suffisante pour renvoyer « violemment/rapidement » le percuteur vers sa position de départ.
- the percussion generates a pulse / kinetic energy which is a function of the percussion speed, which is a function of the running speed of the pick-up vehicle;
- this impulse / kinetic energy retracts the firing pin far from the cone, and in the prototype and the object of the invention, returns the firing pin forward because it is MOBILE; at high speed, this referral is "violent" and therefore "fast";
- the striker thus retracted or returned is stopped by a damping and return means, which can be arbitrary, which dampens the shock and especially returns the striker to its initial position thanks to the kinetic energy "residual" and / or the gravity (if the retraction takes place upwards).
- the skilled person has already understood that for there to exist a kinetic energy "residual", it is appropriate that the kinetic energy created by the percussion is greater than the energy sufficient to return the striker to the damping means / referral; otherwise, there would be no "referral"; the skilled person also understood that said residual energy must be sufficient to return "violently / quickly" the striker to its starting position.
Le « moyen de guidage « peut être quelconque : dans ce qui suit, et sur le prototype réalisé, le bras portant le percuteur est mobile en rotation autour d'un axe perpendiculaire au sens de la marche ; disposé en dessous du niveau de percussion pour le prototype, on peut cependant envisager des équivalents techniques où le percuteur (qui est généralement une barre horizontale également perpendiculaire au sens de la marche) est articulée au dessus de la hauteur de percussion, ou est guidé par deux rails formant chacun une gorge en U horizontal où circule ledit percuteur, avec des roulements à billes pour réduire les frottements.The "guide means" may be arbitrary: in what follows, and on the prototype made, the arm carrying the striker is rotatable about an axis perpendicular to the direction of travel; arranged below the level of percussion for the prototype, one can however consider technical equivalents where the striker (which is generally a horizontal bar also perpendicular to the direction of the march) is articulated above the height of percussion, or is guided by two rails each forming a horizontal U-shaped groove where said striker circulates, with ball bearings to reduce friction.
Enfin, on comprendra que ledit moyen d'amortissement/renvoi peut lui même conférer de l'énergie au percuteur, pour un renvoi encore plus rapide vers sa position initiale : par exemple, ce peut être le cas d'un moyen à ressort, lequel à la fois amortit et restitue de l'énergie au percuteur, ou un vérin, ou même un moyen actif qui emmagasine de l'énergie avant que le percuteur ne l'atteigne, et la restitue lors du choc : notamment un ressort ou un vérin, ou une lame métallique flexible, « prétendus » par un moteur (par exemple à vis sans fin) ou par un vérin asservi, cette « pré-tension » formant une énergie qui est restituée lorsque le percuteur heurte ledit moyen de renvoi (le déclenchement se faisant par un moyen simple tel que un contact électrique, le basculement d'un doigt heurté par le percuteur, etc...).Finally, it will be understood that said damping / return means may itself give energy to the firing pin, for an even faster return to its initial position: for example, this may be the case of a spring means, which at the same time damps and restores energy to the firing pin, or a jack, or even an active means that stores energy before the firing pin reaches it, and restores it when shock: in particular a spring or cylinder, or a flexible metal blade, "alleged" by a motor (for example auger) or by a slave cylinder, this "pre-tension" forming an energy that is restored when the striker strikes said deflection means (the trigger being by a simple means such as an electrical contact, the tilting of a finger struck by the striker, etc ...).
On optera pour les solutions les plus simples (moins de maintenance et coût moindre) notamment un amortisseur hydraulique de type vérin de renvoi, ce qui est le cas envisagé ci-dessous et sur le prototype.We will opt for the simplest solutions (less maintenance and lower cost) including a hydraulic damper type return cylinder, which is the case envisaged below and on the prototype.
Pour les opérations de pose, il suffit de déposer manuellement le cône sur le convoyeur - dont on aura préalablement inversé le sens de rotation - qui va l'accélérer et le déplacer jusqu'à la surface de la chaussée, le « saut » du cône du convoyeur vers la chaussé ne présentant pas de difficulté particulière.For laying operations, simply place the cone on the conveyor - which will have previously reversed the direction of rotation - which will accelerate it and move it to the surface of the road, the "jump" of the cone from the conveyor to the pavement presenting no particular difficulty.
L'homme de métier comprendra à la lecture de ce qui va suivre que l'invention concerne un moyen général qui consiste en :
- un moyen connu de convoyeur associé à un véhicule de ramassage
- un dispositif selon l'invention dont les moyens sont
- un moyen de percussion du cône en marche AR ou AV
- monté pivotant sur un support solidaire dudit convoyeur
- ledit moyen de percussion étant adapté géométriquement et en cinématique pour percuter le cône en un point A légèrement sous le sommet (d'une distance d) dudit cône, et pour incliner le cône vers l'AR sans le renverser,
- à une vitesse suffisante (marche AR du véhicule) pour que ladite percussion contre le cône soulève ledit moyen de percussion ET simultanément le renvoie fortement vers l'AV, ce double mouvement permettant au cône de se dégager dudit moyen de percussion ET de retomber vers l'AV, où sa semelle tombe sur le bord du convoyeur (puisque dans ce laps de temps le véhicule a reculé),
- ledit renvoi vers l'AV dudit moyen de percussion projetant ledit moyen de percussion sur un dispositif d'amortissement/renvoi adapté pour amortir le choc et pour renvoyer rapidement vers l'AR, de manière dynamique, c'est à dire par dissipation de l'énergie du renvoi vers l'AV, ledit dispositif de percussion qui retrouve ainsi très rapidement sa position de départ où il est à nouveau en mesure de percuter le cône suivant.
- a known conveyor means associated with a pickup vehicle
- a device according to the invention whose means are
- a means of percussion of the cone running AR or AV
- pivotally mounted on a support secured to said conveyor
- said percussion means being geometrically and kinematically adapted to strike the cone at a point A slightly below the apex (by a distance d) of said cone, and to tilt the cone towards the AR without reversing it,
- at a sufficient speed (vehicle reverse) so that said percussion against the cone raises said percussion means AND simultaneously strongly returns it to the AV, this double movement allowing the cone to disengage from said percussion means AND to fall back to the 'AV, where his sole falls on the edge of the conveyor (since in this period of time the vehicle has retreated),
- said reference to the AV said percussion means projecting said striking means on a damping / return device adapted to dampen the shock and to quickly return to the AR, dynamically, that is to say by dissipation of the energy of the return to the AV, the percussion device which so quickly finds his starting position where he is again able to hit the next cone.
On comprendra aisément que la caractéristique essentielle est le dispositif de renvoi dynamique, car il remplit deux fonctions essentielles : 1/ escamoter très rapidement le percuteur tout en dosant l'énergie de basculement communiquée au cône, et 2/ renvoyer très rapidement, par un mouvement forcé, après le passage du cône, le moyen de percussion vers sa position initiale où il peut donc très rapidement percuter un nouveau cône.It will easily be understood that the essential characteristic is the dynamic return device, because it fulfills two essential functions: 1 / very quickly retract the striker while dosing the tipping energy communicated to the cone, and 2 / return very quickly, by a movement forced, after the passage of the cone, the percussion means to its initial position where it can very quickly hit a new cone.
Ce renvoi dynamique rapide permet donc une cadence très élevée de ramassage, par exemple 15 à 20 km/h, et même 30 km/h selon les conditions de température.This fast dynamic return allows a very high rate of collection, for example 15 to 20 km / h, and even 30 km / h depending on the temperature conditions.
On notera que l'invention s'applique aussi, a fortiori, aux faibles vitesses si les opérateurs choisissent de travailler à des vitesses faibles. L'invention est donc totalement polyvalente.Note that the invention also applies, a fortiori, low speeds if operators choose to work at low speeds. The invention is therefore totally versatile.
Ledit dispositif d'amortissement/renvoi dynamique peut être passif, par exemple un ressort ou un vérin que le renvoi vers l'AV comprime et qui se détend pour renvoyer le moyen de percussion vers l'AR, ou bien actif, c'est à dire par exemple un vérin motorisé qui est armé durant la phase de renvoi vers l'AR du percuteur, et qui frappe le percuteur en lui donnant une forte impulsion vers l'AR lorsque ledit percuteur le frappe en bout de sa course vers l'AV.Said damping / dynamic return device may be passive, for example a spring or a jack that the return to the AV compresses and which expands to return the percussion means to the AR, or active, it is up to for example, a motorized actuator which is armed during the return phase to the firing pin's AR, and which strikes the striker by giving it a strong impulse towards the AR when the firing striker strikes it at the end of its stroke towards the AV .

Naturellement, le moyen (8) peut être réglable et être étalonné notamment en fonction de la vitesse choisie. Il sera évident à l'homme de métier que, plus la vitesse de ramassage souhaitée sera choisie élevée, plus le moyen de renvoi (8) devra être puissant (on pourra par exemple pré-comprimer le ressort, ou étalonner le vérin s'il s'agit d'un vérin).Naturally, the means (8) can be adjustable and be calibrated in particular according to the speed chosen. It will be obvious to those skilled in the art that the higher the desired collection speed is chosen, the more powerful the return means (8) will be (for example, it will be possible to pre-compress the spring, or to calibrate the jack if this is a jack).
On peut prévoir subsidiairement un moyen d'amortissement du percuteur dans sa position arrière AR (9) c'est à dire en fait une butée qui l'empêche de « rebondir » vers l'avant et assure la bonne hauteur « d » de percussion et un amortisseur qui permet de le stabiliser dans cette position arrière.In the alternative, it is possible to provide a damping means for the firing pin in its rear position AR (9), that is to say in fact an abutment which prevents it from "bouncing" towards the front and ensures the right height "d" of percussion. and a damper that stabilizes it in this rear position.
Ce peut être par exemple un autre amortisseur hydraulique, une butée caoutchouc conique, disposé à une distance adéquate de l'axe de rotation selon sa raideur.This may be for example another hydraulic damper, a conical rubber stop, disposed at a suitable distance from the axis of rotation according to its stiffness.

Le dispositif de percussion (1) de la présente invention comprend un moyen de percussion (3) dynamique étudié pour venir percuter un cône (2) afin de le faire légèrement basculer (il faut soulever suffisamment la semelle pour qu'elle s'engage sur le convoyeur, soit 8 à 12 cm environ) afin que le cône puisse être transporté par un convoyeur (4). Par « moyen de percussion dynamique » on entend que ce moyen est fixé de manière mobile autour d'un point de fixation (7) situé en partie supérieure des parois latérales (11) dudit convoyeur (4) (contrairement à l'art antérieur où ce moyen de percussion est systématiquement non mobile).The percussion device (1) of the present invention comprises a dynamic percussion means (3) designed to strike a cone (2) in order to tilt it slightly (it is necessary to raise the sole enough to engage on the conveyor, about 8 to 12 cm) so that the cone can be transported by a conveyor (4). By "dynamic percussion means" is meant that this means is movably fixed around an attachment point (7) located in the upper part of the side walls (11) of said conveyor (4) (unlike the prior art where this means of percussion is systematically not mobile).
Ledit moyen de percussion (3) est constitué d'au moins un bras articulé (5) monté pivotant selon un axe de rotation perpendiculaire au convoyeur, au niveau dudit point de fixation (7), et qui comporte un élément de type barre de percussion (6) à son extrémité supérieure (parallèle au convoyeur), le moyen de percussion formant sensiblement une forme d'arceau.Said striking means (3) consists of at least one articulated arm (5) pivotally mounted about an axis of rotation perpendicular to the conveyor, at said attachment point (7), and which comprises a percussion bar-type element (6) at its upper end (parallel to the conveyor), the percussion means forming a substantially arch form.
Ledit moyen de percussion (3) est géométriquement adapté de telle manière qu'en reculant, la barre de percussion (6) heurte la partie supérieure du cône, en un point (A) distant du sommet (S) du cône d'une distance (d). Cette distance d est adaptée pour que lorsque la barre de percussion (6) fait basculer le cône par action/percussion sur le point (A), le cône bascule jusqu'à lever suffisamment sa semelle afin que celle-ci puisse retomber sur le convoyeur (4).Said percussion means (3) is geometrically adapted such that, in retreating, the percussion bar (6) strikes the upper part of the cone at a point (A) remote from the vertex (S) of the cone of a distance (d). This distance d is adapted so that when the percussion bar (6) tilts the cone by action / percussion on the point (A), the cone tilts up enough to lift his sole so that it can fall on the conveyor (4).
Le cône (2) et le point (A) sont géométriquement adaptés pour repousser ledit bras articulé autour de son point de fixation (7) en le renvoyant fortement vers l'avant (AV) où le bras articulé (5) heurte un premier moyen d'amortissement et de renvoi (8), qui par réaction à l'énergie transmise par le bras articulé (5), renvoie rapidement ledit bras (et donc la barre de percussion) vers sa position initiale de percussion, tandis que le cône, qui s'est dégagé de la barre de percussion, bascule par gravité vers l'avant (AV) sous ladite barre de percussion et retombe avec sa semelle sur le convoyeur.The cone (2) and the point (A) are geometrically adapted to push said articulated arm around its point of attachment (7) by strongly forcing it forward (AV) where the articulated arm (5) strikes a first means damping and deflection means (8), which by reaction with the energy transmitted by the articulated arm (5), rapidly returns said arm (and thus the percussion bar) to its initial percussion position, while the cone, which has escaped from the percussion bar, gravitates forward (AV) under said percussion bar and lands with its sole on the conveyor.
Ledit premier moyen d'amortissement et de renvoi (8) est situé sur la face arrière de ladite paroi latérale (11). Ledit moyen d'amortissement et de renvoi est avantageusement étudié pour absorber une grande partie de l'énergie transmise par le moyen de percussion après percussion du cône.Said first damping and return means (8) is located on the rear face of said side wall (11). Said damping and return means is advantageously designed to absorb a large part of the energy transmitted by the percussion means after percussion of the cone.
Ledit moyen de percussion peut être également avantageusement constitué d'au moins un second moyen d'amortissement (9), et uniquement d'amortissement, situé sur la face avant de ladite paroi latérale (11), en face dudit premier moyen d'amortissement et de renvoi (8), sur lequel vient reposer, en position de repos, ledit moyen de percussion (c'est-à-dire avant percussion d'un cône).Said percussion means may also advantageously consist of at least a second damping means (9), and only damping, located on the front face of said side wall (11), facing said first damping means and return (8), which comes to rest, in the rest position, said percussion means (that is to say before percussion of a cone).
En fonctionnement, le cône va être percuté par ledit moyen de percussion (3). Le cône va utiliser une partie de l'énergie pour son propre basculement et soulèvement de sa semelle (10), et va transmettre une certaine énergie (créée par l'impact, la vitesse du véhicule, etc, notions physiques élémentaires) au moyen de percussion qui, étant mobile, va s'escamoter ou, selon un mode préféré se projeter en avant en rotation autour de son point de fixation (7) jusqu'à rencontrer ledit premier moyen amortisseur et de renvoi (8).In operation, the cone will be struck by said percussion means (3). The cone will use some of the energy for its own tilting and lifting of its sole (10), and will transmit some energy (created by the impact, the speed of the vehicle, etc., basic physical concepts) by means of percussion which, being mobile , will retract or, in a preferred embodiment projecting forwardly in rotation around its attachment point (7) to meet said first damper and return means (8).
Ledit premier moyen amortisseur et de renvoi (8) va alors absorber une partie de l'énergie, puis va en restituer une partie au moyen de percussion (3) afin de le renvoyer vers sa position initiale dite de repos qui se situe sur ledit second moyen d'amortissement (9). Ce dernier va alors absorber en totalité le restant d'énergie transmise par le moyen de percussion, afin que ce dernier reste en position statique. Une fois cette position statique de repos atteinte, le dispositif est de nouveau opérationnel pour percuter un nouveau cône.Said first damper and return means (8) will then absorb a portion of the energy, then will restore a portion by means of percussion (3) to return it to its initial rest position which is located on said second damping means (9). The latter will then fully absorb the remaining energy transmitted by the percussion means, so that the latter remains in a static position. Once this static rest position is reached, the device is again operational to strike a new cone.
L'homme du métier a donc compris que le coeur de l'invention est un moyen de percussion mobile en rotation, avec « dissipation et utilisation » de l'énergie cinétique créée par le choc avec le cône.Those skilled in the art have therefore understood that the heart of the invention is a moving means of rotation in rotation, with "dissipation and use" of the kinetic energy created by the impact with the cone.
Le dispositif, de par l'interaction du premier moyen d'amortissement et de renvoi (8), du second moyen d'amortissement (9), et du moyen de percussion mobile (3), permet une très grande dissipation du trop plein d'énergie qui pourrait causer des rebonds multiples du moyen de percussion et donc entraver le bon fonctionnement du l'ensemble du dispositif, tout en utilisant l'énergie résiduelle pour renvoyer ledit moyen de percussion vers sa position initiale, l'amortissement et le renvoi « dynamique » rendant possible une accélération de la cadence de ramassage de cône, sans risque de faire chuter le cône.The device, by the interaction of the first damping and deflection means (8), the second damping means (9), and the mobile percussion means (3), allows a very large dissipation of the overflow of energy that could cause multiple bouncing of the percussion means and thus impede the proper functioning of the entire device, while using the residual energy to return said percussion means to its initial position, the damping and the return " dynamic "making it possible to accelerate the rate of collection of cone , without risk of dropping the cone.
Selon la présente invention, plus la vitesse du véhicule est élevée, plus l'impulsion d'escamotage du moyen de percussion (3) est forte et donc ce dernier s'escamote plus vite, évitant au cône de prendre une inclinaison dangereuse. Pour résumer, quelle que soit la vitesse du véhicule (dans des limites raisonnables, c'est-à-dire de 1 à environ 30 km/h) et donc quelle que soit la vitesse à laquelle le moyen de percussion va venir percuter le cône, on aura sensiblement le même choc entre le moyen de percussion et le cône, créant sensiblement le même transfert d'énergie. Dans les cas, où une trop grande quantité d'énergie serait transférée du cône vers le moyen de percussion lors du choc, celle-ci serait absorbée par ledit premier moyen d'amortissement et de renvoi (8), puis par le second moyen d'amortissement (9).According to the present invention, the higher the speed of the vehicle, the stronger the retraction pulse of the percussion means (3) and thus the latter retracts faster, preventing the cone from taking a dangerous inclination . To summarize, regardless of the speed of the vehicle (within reasonable limits, that is to say from 1 to about 30 km / h) and therefore regardless of the speed at which the percussion means will come crashing into the cone it will be substantially the same shock between the percussion means and the cone, creating substantially the same energy transfer. In cases where too much energy would be transferred from the cone to the percussion means during the shock, it would be absorbed by said first damping and return means (8), then by the second damping means (9).
L'obtention de cet ensemble de propriétés, a priori incompatibles entre elles, est tout à fait surprenant.Obtaining this set of properties, a priori incompatible with each other, is quite surprising.
A l'inverse, lorsque l'utilisateur souhaitera poser des cônes sur la route, il lui suffit de retirer le percuteur de l'équipement ou placer le moyen de percussion (3) en position haute, c'est-à-dire dans une position telle que le cône passe tout simplement dessous le moyen de percussion.Conversely, when the user wishes to put cones on the road, it suffices to remove the striker from the equipment or place the percussion means (3) in the up position, that is to say in a position such that the cone simply passes under the percussion means.
Le bras articulé pourra être fixé dans ladite position par tout moyen connu à la paroi latérale (sangles, goupilles, butées etc).The articulated arm may be fixed in said position by any known means to the side wall (straps, pins, stops etc.).
L'utilisateur posera les cônes à intervalles réguliers sur le convoyeur que l'on a au préalablement mis en position de fonctionnement inverse par rapport au fonctionnement de ramassage de cônes, c'est-à-dire pour transporter le cône vers la route.The user will put the cones at regular intervals on the conveyor that has been previously put in the reverse operating position with respect to the operation of collecting cones, that is to say to transport the cone to the road.

L'invention sera décrite plus spécifiquement dans ce qui suit.The invention will be described more specifically in the following.
Comme cela peut-être observé dans la
- un moyen de percussion (3) composé d'au moins un bras articulé (5) monté pivotant selon un axe de rotation perpendiculaire au convoyeur (4), au niveau dudit point de fixation (7), et qui comporte une barre de percussion (6) à son extrémité supérieure (parallèle au convoyeur)
- un premier moyen d'amortissement et de renvoi (8),
- un second moyen d'amortissement (9).
- percussion means (3) composed of at least one articulated arm (5) pivotally mounted along an axis of rotation perpendicular to the conveyor (4), at said point of rotation. fastener (7), and which has an impact bar (6) at its upper end (parallel to the conveyor)
- first damping and return means (8),
- second damping means (9).
Ledit dispositif de percussion (1) étant fixé à deux parois latérales (11), elles-mêmes connectées au convoyeur de cône (4).
Ledit moyen de percussion (3) repose sur ledit second moyen d'amortissement (9), et est en position pour venir percuter un cône (2) afin de le faire basculer.Said percussion device (1) being attached to two side walls (11), themselves connected to the cone conveyor (4).
Said striking means (3) rests on said second damping means (9), and is in position to strike a cone (2) to tilt it.
Dans ce mode de réalisation préféré, le premier moyen d'amortissement et de renvoi (8) est, de préférence, de type amortisseur hydraulique ou tout autre moyen capable d'absorber une certaine quantité d'énergie et de d'en restituer également une partie, tel que par exemple un couple ressort/amortisseur, etc...In this preferred embodiment, the first damping and deflection means (8) is preferably of hydraulic damping type or any other means capable of absorbing a certain amount of energy and also of restoring a certain amount of energy. part, such as for example a spring / damper couple, etc.
Dans le même mode de réalisation préféré, ledit second moyen d'amortissement (9) est de préférence un élément de type butée en caoutchouc suffisamment mou pour absorber l'énergie cinétique qui va lui être transféré par le moyen de percussion (3), afin d'éviter de nouveau tout transfert ultérieur.In the same preferred embodiment, said second damping means (9) is preferably a rubber stop element sufficiently soft to absorb the kinetic energy that will be transferred to it by the percussion means (3), so as to to avoid any further transfer.
Ledit bras articulé (5) est fixé de manière mobile autour d'un point de fixation (7) permettant la rotation autour de ce point du moyen de percussion (3), après percussion du cône (2).Said articulated arm (5) is movably fixed around an attachment point (7) allowing rotation around this point of the percussion means (3), after percussion of the cone (2).
Selon un autre mode de réalisation, le dispositif de percussion (1) comprend deux amortisseurs hydrauliques et deux éléments de type butée caoutchouc disposés sur chacune des parois latérales (11) du convoyeur.According to another embodiment, the percussion device (1) comprises two hydraulic dampers and two rubber-like elements arranged on each of the side walls (11) of the conveyor.
Dans la
Il est possible d'ajouter à l'élément de percussion (6), une masselotte de réglage (non représentée) de l'inertie du percuteur, en particulier lors de variations de la température extérieure pouvant influencer la rigidité du cône (2).It is possible to add to the percussion element (6), a control weight (not shown) of the inertia of the firing pin, in particular during changes in the external temperature that can influence the rigidity of the cone (2).
Dans un mode de réalisation préféré, le distance d est comprise entre 4 et 6 cm, la barre (6) et le bras (5) sont en matériau de type aluminium ou inox et présentent un diamètre de 3 cm.In a preferred embodiment, the distance d is between 4 and 6 cm, the bar (6) and the arm (5) are made of aluminum or stainless steel material and have a diameter of 3 cm.
Le Demandeur a remarqué trois modes de fonctionnement différents selon les vitesses du véhicules (et donc selon la vitesse de percussion) :
- 1. À vitesse « moyenne » (c'est à dire supérieure aux vitesses de l'art antérieur mais encore assez faibles) : 4 à 10 ou 12 km/h. C'est un mode dynamique où l'on cherche à répartir équitablement l'énergie du choc entre le cône (2) et le moyen de percussion (3). L'énergie du choc reçue par le cône (2) sert à soulever la semelle (12), celle reçue par le moyen de percussion (3) sert à le faire s'escamoter. A noter que ce choc sur le cône (2) crée un moment de rotation du cône autour de l'extrémité de sa semelle (10), moment compensé par l'arrivée de la semelle sur le convoyeur (4) qui crée un moment inverse. Cet équilibre participe à la stabilité du cône sur le convoyeur. Le fonctionnement réside dans l'équilibre des inerties et de la répartition de l'énergie.
- 2. À « haute vitesse » au delà de 12-15 km/h jusqu'à environ 18-20 km/h, selon la température : c'est un mode où les forces d'inertie sont dominantes. La percussion est forte et courbe légèrement la partie haute du cône (2) du fait de son élasticité, cependant, le moyen de percussion (3) s'escamote à très vive allure, limitant ainsi la force de basculement exercée sur le cône. Celui-ci est alors plaqué sur le convoyeur par son inertie, le convoyeur le freine et l'achemine vers le véhicule. Le fonctionnement réside dans les rapports d'inerties, la raideur du cône et de l'adhérence sur le convoyeur.
- 3. À petite vitesse de 1 km/h jusqu'à 4 km/h environ, c'est-à-dire les vitesses de l'art antérieur, c'est un mode « quasi-statique » où les forces de gravité sont dominantes. La masse du moyen de percussion (3) doit équilibrer la résistance du cône (2) au basculement, le début de ce basculement entraînant le moyen de percussion (3) vers le haut par adhérence sur le haut du cône (2), la force du moyen de percussion diminue alors et le cône (2) bascule par le haut. La semelle du cône tombe alors sur le convoyeur disposé à distance adéquate. Le fonctionnement réside dans l'équilibre des masses statiques et la géométrie.
- 1. At "average" speed (that is to say higher than the speeds of the prior art but still quite low): 4 to 10 or 12 km / h. It is a dynamic mode where one seeks to distribute equitably the energy of the shock between the cone (2) and the means of percussion (3). The energy of the shock received by the cone (2) is used to lift the sole (12), that received by the percussion means (3) serves to retract it. Note that this impact on the cone (2) creates a moment of rotation of the cone around the end of its sole (10), offset by the arrival of the sole on the conveyor (4) which creates a reverse moment . This balance contributes to the stability of the cone on the conveyor. The operation lies in the balance of inertia and the distribution of energy.
- 2. At "high speed" above 12-15 km / h to about 18-20 km / h, depending on the temperature: this is a mode where the forces of inertia are dominant. The percussion is strong and slightly bent the upper part of the cone (2) due to its elasticity, however, the percussion means (3) retracts at a very fast pace, thus limiting the tilting force exerted on the cone. This is then pressed onto the conveyor by its inertia, the conveyor slows it down and sends it towards the vehicle. The operation lies in the ratios of inertia, the stiffness of the cone and the adhesion on the conveyor.
- 3. At a low speed of 1 km / h to about 4 km / h, that is to say the speeds of the prior art, it is a "quasi-static" mode where the gravitational forces are dominant. The mass of the percussion means (3) must balance the resistance of the cone (2) to the tilting, the beginning of this tilting causing the percussion means (3) upwards by adherence on the top of the cone (2), the force the percussion means then decreases and the cone (2) tilts from above. The sole of the cone then falls on the conveyor arranged at a suitable distance. The operation lies in the static mass balance and the geometry.
Les modes de fonctionnement 1 et 2 sont principalement utilisés avec le dispositif de la présente invention. Aux vitesses élevées (selon l'invention) mentionnées, les dispositifs de l'art antérieur font systématiquement basculer totalement le cône ; ceci a créé dans cette industrie un préjudice contre la recherche de ramassages « rapides ».
Il a été remarqué que même à faible allure (mode de fonctionnement n° 3), la présente invention est plus performante que les dispositifs de l'art antérieur, en raison de la possibilité pour le percuteur de remonter vers le haut en glissant le long du haut du cône, libérant celui-ci avant d'atteindre une inclinaison dangereuse et irréversible ; bien que ceci n'était pas le problème technique que souhaitait résoudre le Demandeur.It has been noticed that even at a low speed (operating mode No. 3), the present invention is more efficient than the prior art devices, because of the possibility for the striker to climb upwards by sliding along from the top of the cone, releasing it before reaching a dangerous and irreversible inclination; although this was not the technical problem that the Claimant wanted to solve.
Pour des cônes plus petits, par exemple de 50 cm de hauteur, la géométrie sera adaptée en conséquence, la masse du percuteur sera diminuée de 30%. De même, si des cônes bi-matières présentent un rapport masse semelle - masse cône différent, la masse et l'inertie du percuteur seront modifiés proportionnellement : ce sont la masse du cône, sa répartition de masse, sa rigidité qui déterminent, par loi de proportionnalité, la masse du percuteur, sa répartition de masse et les valeurs d'amortissement. L'homme de métier saura adapter les dimensionnements des composants de manière à conserver une répartition d'énergie identique à celle définie plus haut entre cône et escamotage du percuteur.
De même, le mouvement d'escamotage du percuteur peut être dirigé vers le haut par un mouvement de rotation, en biais vers le haut par un mouvement de translation, en latéral sur le coté, par un mouvement de rotation ou de translation, ou par déformation d'une liaison élastique présentant des caractéristiques voisines du moyen 8 d'amortissement/renvoi.
Le percuteur peut aussi être constitué comme indiqué en
L'homme de métier saura décliner ce principe avec 3 barres ou plus, ou imaginer d'autres systèmes utilisant une répartition d'énergie contrôlée entre cône et percuteur.For smaller cones, for example 50 cm in height, the geometry will be adapted accordingly, the mass of the striker will be reduced by 30%. Similarly, if bi-material cones have a different mass-to-mass cone ratio, the mass and the inertia of the striker will be proportionally modified: it is the mass of the cone, its mass distribution, its rigidity which determines, by law of proportionality, the mass of the striker, its mass distribution and the damping values. The skilled person will be able to adapt the dimensions of the components so as to maintain an energy distribution identical to that defined above between cone and retraction of the striker.
Similarly, the retraction movement of the firing pin can be directed upwards by a rotational movement, upwardly biased by a translation movement, laterally on the side, by a rotational or translational movement, or by deformation of an elastic connection having characteristics close to the
The striker can also be constituted as indicated in
The skilled person will decline this principle with 3 bars or more, or imagine other systems using a controlled energy distribution between cone and striker.
L'invention couvre également tous les modes de réalisation et toutes les applications qui seront directement accessibles à l'homme de métier à la lecture de la présente demande, et de ses connaissances propres.The invention also covers all the embodiments and all the applications which will be directly accessible to the person skilled in the art upon reading the present application, and of his own knowledge.

- Device according to any one of Claims 7 to 13, characterised in that the distance d is between 4 and 6 cm, and the bar (6) and the arm (5) are made of an aluminium or stainless steel type material.
- Device according to any one of Claims 7 to 14, characterised in that for smaller cones, for example with a height of 50 cm, the geometry will be adapted accordingly, and the weight of the striker will be reduced by 30%; likewise, if bi-material cones have a different baseplate/cone mass ratio, the mass and the inertia of the striker will be proportionately modified: this will include the mass of the cone, its weight distribution and its rigidity which determine, by the law of proportionality, the mass of the striker, its weight distribution and the damping values.
- Device according to any one of Claims 7 to 15, characterised in that, likewise, the retraction movement of the striker can be upwards by a rotational movement, obliquely upwards by a traversing movement, laterally to the side, by a rotational or traversing movement, or by deformation of a resilient connection having characteristics similar to the damping/return means (8).
- Device according to any one of Claims 7 to 16, characterised in that the striker can also be composed of a double bar pivoting with a circular movement in half turns: the impact of a first cone places the alternate double striker assembly in rotation through a half turn while the cone passes beneath, the second bar of the striker then arrives at the striking position and the assembly is stopped in position by a damping means, the impact of a second cone producing on this second bar the same effect as on the first, and so on.
- Method for collecting marker cones, characterised in that it employs the device for rapidly collecting and optionally placing marker cones according to Claims 1 to 17.
- Method for placing marker cones employing the device according to Claims 1 to 17, characterised in that the striker is removed from the equipment or the striking means (3) is placed in a high position, that is in a position such that the cone simply passes beneath the striking means; the articulated arm can be fixed in said position by any known means to the side wall; and in that the cones are placed at regular intervals on the conveyor that has been placed in the inverse operating position relative to the operation of collecting cones, that is for conveying the cone towards the road.
